Description

• The present invention relates to exercise equipment, and in particular to home exercise equipment, such as, for example, resistance weight machines.
• Many people take part in weight training or aerobic exercise in order to improve fitness, increase strength and improve muscle tone. People may choose to exercise at a public gym or health club, or alternatively may choose to install gym equipment within their own property. Owning home gym equipment may be preferable for many people as it provides the user with the convenience of exercising at home, thereby avoiding the cost, travel and social implications of exercising at a communal gym.
• A disadvantage associated with conventional home gym equipment is its size. For example, a bench press, a rowing machine or a chest press require a large amount of floor space. In order for a personal home gym to comprise a sufficient variety of equipment, it is often required that an entire room in a person's house is dedicated to being a home gym. Even then, the average garage or spare room within a typical home is often not large enough to safely house a wide variety of exercise machines.
• In an attempt to overcome the problem of the large amount of room and floor space required for a home gym comprising a large variety of gym equipment, so-called multi-gyms have become well known in the prior art. Multi-gyms generally provide a variety of weight resistance apparatus in one single machine. However, multi-gyms themselves are large and generally take up a significant amount of floor space and room, typically approximately two to three cubic metres or more. This is at least in part due to the need for a multi-gym to accommodate a weight stack safely, thereby requiring a frame with sufficient spacing between its feet so as to be stable. The spacing between the feet causes conventional multi-gyms to have a large footprint, thereby eating into the available floor space within a room.
• Multi-gyms are commonly designed for a user to move around different pieces of equipment in a circle or circuit, performing different exercises at the different pieces of equipment. This necessitates a circular or curved floor plan, which therefore results in unused space in a typical rectangular room with planar walls.
• Furthermore, whilst it has been proposed that a more limited number of very specific exercises may be performed in a relatively smaller space, the limiting of multi-gyms to a specific few exercises only detracts from its value and appeal to the end user.
• If a multi-gym is intended to accommodate various seated or reclining exercise positions then this typically incurs a significant spatial penalty.
• It is an object of the present invention to provide exercise apparatus that overcomes one or more disadvantage of conventional home gym equipment. It may be considered an additional or alternative aim to provide resistance weight equipment offering a relatively small form factor, whilst providing the opportunity for the user to undertake a variety of different exercises.
• According to a first aspect of the invention there is provided exercise apparatus comprising a weight source operably connected to a plurality of manual actuators by a cable and pulley system comprising a plurality of pulley wheels, a supporting frame for the weight source and pulley wheels, and a cable defining a force path from the weight source over the pulley wheels, wherein the pulley wheels and frame are provided in a common plane with the weight source when the exercise apparatus is not in use, and the manual actuators are connected at fixed spaced locations along the path defined by the cable length and are actuatable in a direction away from the common plane when in use, wherein the frame is supported in an upright orientation for use by a support structure.
• The weight source may thus be actuated by the cable and pulley system in a direction within the common plane during use, e.g. within a vertical plane. This, in combination with the support by a support structure, allows the exercise apparatus to be accommodated in a very small depth, such that it can stand flat against the support structure.
• The support structure may comprise a planar support structure, such as a wall. Additionally or alternatively, the support structure may comprise a generally horizontal support structure, such as a floor or a base. The frame may be attached to the support structure by one or more fasteners, such as bolts or the like.
• The frame may comprise a two-dimensional frame structure. The frame may comprise one or more frame member extending in a direction within the common plane. Typically the frame member comprises or consists of a plurality of frame members, all of which extend in directions within the common plane. The frame may comprise a plurality of angled frame members, e.g. perpendicular frame members. The plurality of frame members may be rigidly/permanently affixed within the planar alignment. The entire frame may be aligned with the common plane, e.g. at least in a storage condition.
• The exercise apparatus including the frame, weight stack and pulley wheel according to the invention may be beneficially thin in profile, e.g. having a depth dimension of less than 500 mm. The depth may be less than 400 mm, 300 mm or even less than 200 mm, e.g. in the region of, or less than, 150 mm or 100 mm. A range of 50-200 mm depth or 80-100 mm is entirely practical using the present invention. Thus the distance by which the exercise equipment protrudes into a room, at least when not in use, from a suitable supporting structure, such as a wall, is beneficially small.
• The invention may allow exercise equipment to be installed in rooms without occupying a detrimental volume of the room, e.g. allowing the room to provide an additional function other than being purely used as an exercise room.
• The weight source may be variable. For example, the weight source may comprise a stack of weights, and a user may select a desired weight from the weight source, e.g. by selecting the number of weights or the height of the stack to be lifted by the cable. Actuation of the manual actuator typically applies tension to the cable in a direction so as to oppose the direction of applied weight by the weight source, i.e. to lift the weight source in use. A common/single weight source may be provided for all the actuators, e.g. connected thereto by a common cable.
• A plurality of types of manual actuator may be provided.
• The weight source may be a common weight source. Each actuator may be individually or collectively connected to the weight source, e.g. in series or parallel. A plurality of manual actuators may be connected at differing lengths/locations along the cable, e.g. at different cable length spacing from the weight source. Different/adjacent manual actuators may be spaced by one or more pulley wheel. This may allow each manual actuator to apply tension to the cable in a different direction or orientation or at a different height from one or more further manual actuator.
• The equipment may comprise three or four or five or more manual actuators and/or pulley wheels. The exercise equipment may comprise a variety of manual actuator types, such as any combination of one or more bar, one or more handle, one or more strap or the like. The manual actuators may be connectable to the pulley system at various locations on the pulley system. Multiple actuators may be attachable to a single/common cable of the pulley system. The manual actuators may be releasably connectable to the cable, e.g. in order that a user may selectively add/remove actuators or change the position of the actuators on the cable.
• The cable may comprise a plurality of manual actuator connection locations or formations along its length. The connection formations may or may not comprise any of eyes, links, clips, loops or the like. The connection locations may allow bifurcation of the cable, i.e. a common cable section connecting to the weight source, for example by providing one or more junction to a branching cable section.
• Any, any combination, or all of the manual actuators may be directly/indirectly attached to a fixed point on the cable
• Any, any combination, or all of the manual actuators may be connected to a branching cable section, e.g. midway along its length or at an end thereof. A branching cable section may be connected to the common cable section at one end and to any of a manual actuator, a location on the frame or a hanging counterweight at an opposing end. A branching cable section may be connected to an anchor/fastener location on the frame at its opposing end, either directly or via an intervening length of connecting cable, chain, cord of the like.
• One or more branching cable section may pass around a corresponding/branching pulley. The manual actuator may be connected upstream or downstream of the pulley in the direction of applied tension. Such a pulley may be advantageous in controlling motion of the branching cable section and/or ensuring that a sufficient length of branching cable is available for a full range of manual actuation. A branching pulley wheel may be off-set, e.g. angularly, from the plurality of pulley wheel, e.g. in order to accommodate for the cable to be pulled in a direction that is out of the common plane of the frame and weight source in use.
• The exercise equipment may comprise a single/common cable or cable portion. Alternatively the exercise equipment may comprise two or more cables or cable portions. The two or more cables may be operably connected to the weight source. A common cable portion may or may not bifurcate into two or more branching/parallel cable sections. The exercise equipment may comprise two or more weight sources and the two or more cables or cable sections may be connected to different weight sources.
• The cable may comprise or consist of a cord. The cable may comprise or consist of a chain.
• The/each pulley wheel typically comprises a wheel mounted to a static support structure via bearings. The at least one pulley wheel may be a conventional pulley wheel. Alternatively where the cable comprises a chain, the at least one pulley wheel may be a sprocket wheel.
• A first pulley wheel may be the first point of contact for the cable that extends from the weight source, thereby being the closest pulley wheel in the force path of the cable from the weight source. A second pulley wheel is spaced from the first pulley wheel and the weight source, such that it is the second pulley wheel in the force path of the cable from the weight source. The second pulley wheel and/or a subsequent pulley wheel may be off-set, e.g. angularly, from the first pulley wheel in use, e.g. in order to accommodate for the cable to be pulled in a direction that is out of the common plane of the frame and weight source in use.
• At least four or five pulleys may be provided for the common cable section. At least two or more pulleys may be provided on the frame for branching cable sections.
• The cable may extend around the first pulley wheel towards a second and/or subsequent pulley wheels so as to define a cable circuit, e.g. an open-ended circuit, follows the force path from the weight stack to an opposing end of the cable. The pulley wheel(s) may comprise one or more cable guide(s).
• A first end of the cable may be attached to the weight source. An opposing end of the cable may be attached to a manual actuator.
• One or more cable guide, e.g. a linear cable guide, may be provided, e.g. separately from the one or more pulley. The cable guide may comprise a runner or slider attached to a point on the cable, e.g. an intermediate portion of the cable spaced from the cable ends, such as on the common cable section and/or a branching cable section. The runner may be attached to, or constrained by, a linear guide, such as a slot or track.
• In any cable guide example, the cable guides may prevent the cable from twisting, jumping or snagging, e.g. during tensioning and release of the cable in use.
• Additionally or alternatively, one or more swivel connector may be provided in the cable and pulley system to prevent twisting of the cable, e.g. part-way along the cable length. Adjacent cable sections may be connected by swivel connectors, e.g. at locations between adjacent pulley wheels. A swivel connector may be provided at the junction between the common cable and one or more branch sections.
• A plurality of the pulley wheel(s) may have an axis of rotation this is substantially perpendicular to the common plane. A pulley wheel that is adjacent a manual actuator may be angularly offset from one or more further pulley wheel in use.
• The at least one pulley wheel may be rotatable around an axis that is in the common plane, in order that the pulley wheel may rotate out of the common plane. The at least one pulley wheel may be rotatable through use of a hinge or swivel. The at least one pulley wheel may be in the common plane in use. Alternatively, the at least one pulley wheel may be rotated around the axis such that the pulley wheel is out of the common plane in use. The pulley wheel being rotatable such that it may be rotated out of the common frame is advantageous as it allows a user to move the manual actuator in use in a direction that is out of the common plane of the frame.
• There may be provided cable guides on the frame, for example hooks, or eyes which may extend at least partially around the cable. The cable guides may provide a location around which the cable may bend when a user pulls on an actuator, thereby providing the location from which the cable, e.g. a branching portion thereof, is pulled out of the common plane of the frame and weights source. The position of the hooks relative to the frame may be variable, in order that a user may pull the cable from different locations of the pulley system to carry out different exercises. Additionally or alternatively, the cable guides may serve to maintain the correct orientation of the cable within the common plane, e.g. adjacent a pulley wheel or part/mid way between spaced pulley wheels.
• The manual actuator may comprise a bar, e.g. having two spaced handle/grip portions, or a single handle, stirrup or a pair of handles/stirrups connected to a common location on the cable. The manual actuator may comprise a liner actuator or a pivoting/rotating actuator. The actuator may comprise a mechanism, such as a lever.
• In use, a user may pull the manual actuator in a direction that is in the common plane or out of the common plane. Pulling the manual actuator may cause the weight source to be lifted in an upwards direction. Releasing the manual actuator may cause the weight source to move vertically downwards to its original position.
• One manual actuator may comprise a rowing action actuator. One manual actuator may comprise a pulldown bar or T-bar.
• The pulley system may comprise one or more counterweight. A counter weight may be located within the frame, e.g. within the common plane and may serve to maintain a desired tension in the cable, e.g. to dampen cable motion. One or more of the multiple manual actuators attached to the single cable of the pulley system may act as counterweights. One of the multiple manual actuators may act as a counterweight when that actuator is attached to the pulley system but that actuator is not in use for a particular exercise being carried out on the exercise equipment. The actuators may therefore comprise a weight source suitable to act as a counter weight. The swivels may or may not act as counterweights. The counterweights may ensure that there is sufficient tension in the cable when the exercise equipment is in use in order that the cable is not loose and does not twist, loop or tangle, either under load or when the load is released and the cable returns to its original position.
• In some embodiments, the pulley system and frame may be fixed. In other embodiments, at least part of the pulley system and/or frame may be movable relative to the remainder of the pulley system and or frame. When the exercise equipment is not in use, for example in a storage condition, the frame and pulley system may be arranged such that the frame, pulley system and weight source are in a common plane. In use, portions of the pulley system and/or frame may rotate or fold out of the common plane of the weight source and the remainder of the pulley system and frame. Only one or more selected portions of the frame and/or pulley system may be rotated or folded out of the plane of the common plane; the remainder of the frame and pulley system may be fixed relative to the support structure. In a usage condition, at rest a majority of the cable and pulley system may remain oriented in the common plane.
• The exercise equipment may comprise a seat that folds out from the frame. The seat may be a sliding seat, for example the seat of a rowing machine. The seat may be fixed or lockable and may be for the user to sit when undertaking certain weight exercises. The seat may comprise one or more leg, e.g. a foldable leg, to support the seat on the ground when in use.
• The exercise equipment may be embedded/mounted within the surface of a wall or affixed against an interior or exterior wall surface of a building. The wall or wall surface may provide a planar support structure.
• The exercise equipment may comprise a cover, for example a blind or removable panel, such that it is hidden from view when not in use.
• In examples of the invention wherein the exercise equipment is mounted in a wall cavity, there may be provided openings in the wall surface wherein actuators may be attached to the pulley system. Alternatively, openings may be provided in a panel that covers the exercise equipment, through which actuators may be attached to the pulley system.
• The exercise equipment may comprise further exercise apparatus that may be attached to the frame, but not part of the pulley system. For example, the exercise equipment may comprise a stepper/treadle that may fold out of the frame. The further exercise apparatus that may be attached to the frame but not form part of the pulley system may comprise a separate weight source. Alternatively, resistance provided in the further exercise apparatus may be elastic or magnetic resistance. One or more gear wheel and a chain may be used to allow force transfer between a pair of levers or other actuators of the further exercise apparatus.
• An embodiment of the invention will be described in further detail below, by way of example only, with reference to the accompanying drawings of which:
• FIG. 1 is a front view of the apparatus in a first configuration according to an example of the invention; and
• FIG. 2 is a front view of the apparatus in a second configuration according to an example of the invention; and
• FIG. 3 shows a front view of a portion of exercise equipment according to an example of the invention, including further constructional detail.
• As shown inFIGS. 1 and 2, the exercise equipment comprises aframe10 and apulley system12. The frame comprises a series of frame members or bars14 which are arranged in the same plane and provide a fixed structure of the exercise equipment. Thebars14 provide support for the frame and also provide a location to whichpulley wheels16 may be attached. In the first configuration, as shown inFIG. 1, the exercise equipment is in its storage arrangement; in the second configuration, as shown inFIG. 2, the exercise equipment is in an arrangement suitable for use.
• InFIG. 1 all the pulleys are mounted in a common plane to theframe10 at least in a storage condition, although one or more pulley may be actuatable away from said plane for use as will be described hereinbelow.
• The frame is generally rectangular in plan, comprising uprights14aandcross members14bextending there-between. In this example one or more intermediate frame members span the uprights and/or cross bars to provide additional support and a mounting location for one or more pulley wheel. The intermediate frame members may compriseuprights14c, cross members.14dand/oroblique members14eas necessary and may extend the full distance between opposing/adjacentouter frame members14a,14bor part-way there-between, e.g. being affixed to one or more further intermediate member.
• The exercise equipment comprises aweight source18 which is made up of a stack ofindividual weights20, i.e. a so-called weight stack. Theweight stack18 may be conventional in form having a central opening, through which a selector member extends. The required weight to provide a desired resistance for a particular exercise may be selected by the user in a conventional manner by inserting a pin at the desired location in the selector member so as to include/exclude the desired number of weights from the weight stack in the force path connected to the cable. Such an arrangement is known in the art and will not be described or shown in detail for brevity.
• However theweights20 are bespoke to the present design, being of reduced depth dimension, the depth of the weights being sufficiently small that they do not protrude at all or to any significant extent beyond the depth of theframe10. The depth of the weights and weight stack as a whole from front to back is preferably less than 150 mm or 120 mm and ideally of 100 mm or lower depth.
• Theweight stack18 is generally centrally aligned within the frame, e.g. to allow positioning of exercise equipment on either side thereof, although this is not essential. Preferably theweight stack18 is within the perimeter of the frame. The weight stack may be constrained between frame uprights orintermediate frame members14c.
• Acable22 forms a circuit around the various pulley wheels that is entirely contained within the frame perimeter.
• Thecable22 is attached to theweight stack18 and extends vertically upwards towards afirst pulley wheel24 which is fixed to abar14dof theframe10. Thecable22 extends around the first pulley wheel towards a second andsubsequent pulley wheels16 that are fixed to the frame in different locations, typically all within a common plane. A path for thecable22 is thereby provided in the common plane of theframe10 and the majority or all of the cable length is held within the plane when at rest.
• The arrangement ofpulley wheels16 on theframe10, and therefore the layout of the cable path, may vary in different embodiments of the invention, i.e. to allow for different exercises or combinations of exercises. However each different exercise orientation will typically require at least one pulley. A multi-gym arrangement of the type shown will thus comprise four, five, six, or more pulley wheels and typically ten or more pulley wheels.
• Acounter weight26 may be provided at one or more location on the pulley system, in order to ensure that sufficient tension is maintained in thecable22. The counter weight may be suspended from the cable by a pulley wheel (e.g. such that its position along the cable is adjustable) or may be suspended between two pulleys in the system. Maintaining sufficient tension in the cable may help to prevent any twisting or looping in the cable and to prevent the cable becoming accidentally hooked onto parts of the equipment or dislodged from the pulley wheels. As an alternative to a counter weight, a spring or other elastic member could be used to maintain tension in thecable22. For example, a sprung loaded arm could carry a pulley wheel to deflect the path of the cable at rest. Tension in thecable22 applied by a user may act against the spring load in use such, i.e. such that upon release of the user-applied tension, the spring will return the cable path to its at-rest, deflected path. This may act in a manner similar to acounter weight26 without requiring a hanging mass.
• At the end of thecable22 there is provided a hand-heldpull bar28, or T-bar, which may hang down from afinal pulley wheel30 in the system and may be pulled generally downwards by a user during exercise. As the pull-bar28 is pulled vertically downwards, thecable22 moves around the path in a first direction and theweight stack18 is lifted. As the pull-bar28 is released, moving vertically upwards, thecable22 moves around the path in a second direction, opposite to the first direction, and theweight stack18 is moved downwards towards its original position.
• Thepulley wheel30, which is at a position in the force path of thecable22 closest to the hand-held pull-bar28, is selectively repositionable, i.e. hinged/rotatable in this example. Thepulley wheel30 may be mounted to a suitable hinged bracket or similar which may be selectively locked at the desired orientation for use.
• As shown inFIG. 2, thepulley wheel30 may be rotated such it is out of plane of theframe10, thereby allowing thecable22 to extend outwards of the plane of theframe10 such that the pull-bar28 is off-set from the plane of theframe10 andweight stack18 in use. This allows a user to sit or stand in front of the exercise equipment and pull down the hand-heldbar28 from above, thereby lifting the weights, as indicated by the arrows inFIG. 2.
• In other examples of the invention, the end of thecable22 and an associated manual actuator could be oppositely oriented, e.g. such that it is required to be raised rather than lowered in use to raise theweight stack18. This could be used for example to allow an exercise akin to a bench press, arm or leg curls, or similar.
• Manual actuators32 may also be attached to thepulley system12 at various locations in the system, i.e. part-way along the length of thecable22. Theactuators32 are connected to thecable22 using suitable connectors.
• Cable guides34 are provided on theframe10 of the equipment at locations according to the positions of themanual actuators32 and/orpulley wheels16. Theguides32 serve to constrain the motion of thecable22 where necessary according to the exercise to be performed, e.g. to prevent unwanted portions of the cable being pulled away from the plane of the frame during exercise. This helps ensure that cable tension is transferred to theweight stack18, rather than just resulting in bowing of the cable, and also ensures the cable is correctly aligned to run smoothly over the pulley wheels.
• Theguides34 may be looped around thecable22 in use and may take the form of hooks or eye formations, preferably having a smooth and/or curved contact surface over which the cable can run in use. This is important as the guides may provide a point of deflection of the cable during actuation by a user. Theguides34 can thus provide a location around which thecable22 may be pulled, in order that the user may carry out a desired exercise by pulling the actuator32 from a desired location.
• The manual actuators may be releasably connectable to the cable, in order that a user may change the position of the actuators on the cable. Similarly, the position relative to the frame at which the guides/hooks34 may constrain the cable may be variable. Theguides34 may clamp onto the frame at desired locations or else may attach to the frame using suitable fasteners, e.g. releasable fasteners, such as bolts, latches or slot and groove formations.
• An actuator that is connected to the pulley system and is not in use for a particular exercise may act as a counterweight for the system, thereby ensuring the cable maintains a required tension. The actuators may therefore be made of a substantially dense/heavy material that they may act as a counterweight.
• The exercise equipment comprises arowing machine36. The rowing machine comprises abench38 withfeet40 and a sliding seat42 (seeFIG. 2) that may slide along thebench38, e.g. along a runner. When the exercise equipment is in a storage configuration, therowing machine36, e.g. thebench38 and/orfeet40, may be folded upright such that it is stored flat within the frame. In use, therowing machine36 may be folded out such that thefeet40 engage with the floor, and a user may sit on the slidingseat42, facing theframe10 of the equipment. Thefeet40 may be hingedly mounted to the bench or runner and may fold down, e.g. may swing down under their own weight, as thebench38 is lowered for use. The feet could be manually actuated and/or locked in position for use as required.
• A hand-held pull-bar44 is attached to thepulley system12 at a position adjacent thebench38, in order that a user may pull the pull-bar44 in a direction perpendicular to the plane of theframe10, whilst sliding on theseat42 along thebench38.
• As with thepull bar28, thepull bar44 is connected to the cable and thus defines a force path to theweight stack18 such that it can be used to raise theweights20 in use.
• Since thepull bar44 andactuators32 are part-way along thecable22, rather than being at its free end. Astop member46, shown inFIG. 1, may be used to resist retraction of the free end of thecable22 beyond a predetermined position. Thestop member46 may depend from the frame and may abut theactuator28 when fully retracted. Thus the tension applied by the user via the intermediate actuators will transfer to a raising force on the weight stack rather than further retraction of the cable end. In other examples, thestop member46 may comprise a guide member or a clamp.
• Whilst the examples ofFIGS. 1 and 2 show only a few types of actuator, the cable may be coupled with a variety of different actuators, including for example a lever or a pair of levers, which may be permanently or selectively coupled to the cable at a suitable point along its length. Thus the system may accommodate a wide variety of reciprocating actuators to cause raising and lowering of theweight stack18. Such actuators could include a bench press, treadle, or cross trainer, in addition to or instead of the linear actuators shown inFIGS. 1 and 2.
• Whilst theend actuator28 in the examples ofFIGS. 1 and 2 has abespoke pulley wheel30 that can be repositioned/reoriented between a flat storage condition and an in-use condition, it will be appreciated that such a feature could be applied to any actuator and/or pulley in the system as required. Any such pulley could be mounted on a frame member that can hinge or swing out of the common plane of the remainder of theframe10 into position for a suitable exercise to be performed.
• Furthermore, whilst thecable22 starts at theweight stack18 and terminates at its free end at thepull bar28, in other examples, thecable22 could terminate at a lower location, e.g. for a lat curl bar or other exercise. Alternatively, the cable could terminate at a connection with the frame.
• Other than the option of a repositionable pulley wheel and/or corresponding frame member, the frame is of a generally rigid construction so as to maintain its planar form. Thus the frame is not self-supporting in use and instead requires attachment to a suitable support structure. For this purpose, theframe10 comprises fixingformations48 mounted to the frame such that the frame can be attached to a suitable support using bolts or other conventional fasteners. In this example the frame is bolted to a wall such that the common plane of the frame is parallel with that of the wall. In this arrangement, the equipment lies flush against a wall and takes up minimal internal room space.
• The frame may be attached to a wall at its four corners or at any suitable locations on the frame structure, typically at multiple locations about the perimeter of the frame and/or intermediate frame members. In some examples, theframe10 may be located within a recess in a wall, such as an alcove or else by removal of a section of an interior wall leaf, such that frame becomes embedded in the wall and does not protrude beyond the wall surface.
• In other examples of the invention, it may be desirable not to attach theframe10 to a wall. In such examples a base could be used to secure the upright orientation of theframe10. A suitable base may comprise one or more legs, typically at least two legs, extending forwardly, e.g. perpendicularly of the plane of theframe10 along the floor. The legs thus prevent toppling of theframe10 in use. Thus the frame may lie parallel with a wall of a room without requiring attachment to the wall. The frame may lie against the wall or spaced therefrom by a small gap, e.g. with one or more suitable spacer member being provided on the frame. Alternatively, the base construction may allow the frame to be positioned as desired within the interior of a room, without occupying the volume of a 3-D frame structure associated with conventional multi-gyms.
• Turning toFIG. 3, there is shown further details of the cable and pulley system features as well as details of cable junctions for connecting manual actuators to thecable22. Thecable22 described above thus comprises a main or common cable length having one ormore connectors52 defining junctions at which one or more branchingcable section54 can be connected.
• The branchingcable section54 passes round adedicated pulley58, i.e. a branching pulley which does not serve as a guide for themain cable section22.
• The branchingcable section54 is connected to theconnector52 at one end and to a suitable location on theframe10 at its other end, e.g. at aframe fixture56, such as an eye or other formation at which the cable can terminate. In this example, the branchingcable section54 is connected to the frame via an intermediateelastic material section59 in order to maintain the desired tension (e.g. to avoid any slack in thebranch section54 in use). In alternative arrangements, the branch section could pass over a pulley and terminate at a hanging weight (i.e. a counterweight), rather than a connection to theframe10 in order to maintain the desired cable tension.
• Themanual actuator60 is connected to the branchingcable section54 instead of thecommon cable section22.
• Whilst the othermanual actuators28,32 are not shown as being connected to branch connectors inFIGS. 1 and 2, it will be appreciated that any, any combination or all of the manual actuators could be connected in this manner. This kind of branching connection allows manual actuators to be easily connected to or removed from the main/common cable22 at various points within the cable circuit. It also allows selective positioning of manual actuators in the circuit at locations that may otherwise be inconvenient due to the locations of the common cable pulleys16. The branching of the cable may also allow a greater range of movement for anactuator32 to suit a particular exercise.
• One such actuator which is desirable to attach to a branching actuator in this manner is the rowingmachine pull bar44. In such an example, a connector currently used for the attachment ofactuator32 inFIG. 3 may additionally or alternatively be used to attach a branch cable which runs around a branch pulley to theactuator44. The branch pulley in this example may be angled so as to guide the branch cable out of the common plane of theframe10, i.e. in a direction out of the page ofFIG. 3. In a prototype of the invention, the branch cable has a clip, such as a carabiner clip or similar such that theactuator44 can be selectively attached to, or removed from, the cable and pulley system. The free end of the branch cable may be attached to the frame or a counter weight in the manner hereinbefore described when the rowing machine is not in use. In other examples, theactuator44 could remain permanently connected.
• According to any aspect of the invention, the cable may comprise a common cable extending from the weight source to an opposing end and a plurality of branching cable sections depending from fixed locations of the common cable, e.g. in a dendritic or tree-like manner.
• Further details of theconnector52 are shown enlarged and comprise first52A and second52B connector sections, joined at apivot62. A first part of themain cable section22A connects to thefirst connector section52A and a second part of themain cable section22B connects to thesecond connector section52B. The respective connector sections may comprise eyelets or other suitable formations for cable attachment. Thebranch cable54 may connect to either the first orsecond connector section52A or52B as required. Regardless of whether a branching cable section is connected or not, the freedom to permit swiveling between the first and second connector sections allows relief of twisting forces in the cable caused by tension and movement of the cable over pulleys in use. As an alternative, a simple ring connector or other non-swiveling connector could be used. However the ability to relieve twisting forces in the cable has been found to be particularly beneficial.
• Also, regardless of whether a branch cable section is used,FIG. 3 shows a further/alternative type ofcable guide64, an elongate guide, which may be used to maintain a desired orientation of thecable22 during actuation. Theguide64 in this example extends in the direction of an intermediate length of thecable22, e.g. between two pulleys in the system. A slider orrunner66 is mounted to theguide64. The cable is attached to therunner66 to thereby constrain motion of the intermediate portion of thecable22 to the direction of theguide64. This has been found to be particularly useful to ensure smooth, snag-free movement of the cable in use. The guide may be used in either of the embodiments ofFIGS. 1 and 2, in conjunction with, or without, one or more branch cable sections and/orconnectors52 as required.
• It has been found that the invention is sufficiently thin as to lend itself to mounting within a wall, i.e. between embedded within a surface of a wall structure. The frame and the moving cable and pulley system may be exposed or covered by rigid or flexible sheet material to conceal the system. One or more openings in the sheet material may allow the cord to pass into the internal space of a room so as to allow actuation by a user within the room. A sheet/cover of wood or plasterboard or the like, may be used for more permanent installations. The invention may be well suited to mounting against or within the wall of a garden room, or similar, construction.
• It will also be appreciated that the frame and exercise equipment could be mounted on an exterior supporting structure or wall if preferred. If mounted on the exterior surface of a building, the cover may protect the apparatus from the elements.
• In other examples of the invention, the rigid frame structure of the invention could be mounted to other planar support structures which may be static or moveable between different modes of operation. For example the frame could be mounted in a generally horizontal condition to the underside of a bed or the like, which could be elevated/raised to an upright configuration in the event that it is desired to use the gym equipment. A lock latch would thus be required to maintain the support structure in an upright configuration when exercising.
• In further examples, as described above, the frame could be mounted to a base structure such that a planar/vertical support structure is not required. Thus the frame could be free-standing. The frame in conjunction with the base could be generally L-shaped in plan or else in the form of an inverted T shape. The frame could comprise one or more legs that are pivotable from the main frame structure, or that have a sliding telescopic structure. The legs could press against an opposing wall or skirting board for support.
• Thus according to various aspects of the invention, the exercise system is characterised by its reduced depth such that it is not self-supporting and requires fixing to a suitable support structure such as the wall of a building, a base or the like, or requires legs to be fixed to the frame for support.
• Other gym equipment could be mounted to the frame, e.g. towards the left hand side of the frame shown inFIGS. 1 and 2, but without connection to thecable22 if desired. In one example a treadle system, e.g. a stepper, is connected to the lower horizontal frame member in that region, which can pivot between a raised storage condition and a lowered usage condition. In the storage condition, the treadle may be flush with the common plane of theframe10. Thus the frame may accommodate other exercise equipment that does not require connection to the cable circuit described herein.
