Several different training apparatuses are known which are intended for indoor use. However, the majority of these apparatuses are very specialized in that it is only possible to carry out a single exercise on each apparatus. Additionally such apparatuses are often very noisy in operation.

Another disadvantage of the known training apparatuses is that they are usually very heavy and occupy a large space and in certain cases require a special room. Accordingly, such apparatuses cannot be used, for instance, in a room of a house. Further, such apparatuses Possible to Perry Qytmmx matdyfll ffere Q2291"...

cises. Moreover, for each individual exercise a number of intermediate exercises are possible.

The apparatus of the invention makes little noise and is intended for use by any person, e.g. for athletes, handicapped people, people who are convalescing, children and average people, etc.

The apparatus of the invention is small and lightweight and reasonably priced. There are no friction elements, brakes or cog-wheels, etc. Moreover, the apparatus can be folded up when not in use to enable easy storing thereof to be effected.

The apparatus of the present invention is so constructed that it can be utilised by any person without complex instructions being necessary.

According to the present invention, there is provided a training apparatus comprising a framework, two platforms, one end of each platform being pivotally connected to the framework, the platforms being substantially parallel to one anotherand being pivoted at adjacent ends, a supporting member, adjustable in length, being located between the substantially parallel platforms and beingpivotally connected at one end to the framework, a crossbar being detachably fitted at the other end of the supporting member and one or more force-transmitting or tractive means being provided for retaining the supporting member in different desired angular positions, and/or for movably interconnecting the two platforms and/or for connecting via the crossbar to a displaceable device, when the training apparatus is in use.

The appended drawings show schematically some examples of how to make use of the apparatus. It will be apparent from the drawings how the apparatus can be used placed on the floor, as well as how it can be usedhanging up on a wall. The apparatus can also be adjusted and used for walk-and-run training, rowing apparatus, gymnastic apparatus, push and stretch apparatus, swing or playing apparatus for children, besides constituting an excellent body exercising apparatus for both adults and children. However, it is not possible to mention all the different possibilities of the apparatus. Therefore, the description is primarily aimed at explaining the principle of the construction of the apparatus and some examples of how it functions. At all times it is ones own body weight that constitutes the direct resistance in the apparatus.

The apparatus is in principle based on utilizing a balance arrangement. Theperformer can decide for himself how strenuous the exercises are to be and what groups of muscles are to be trained, accordingly from zero effort to a maximum effort can be applied. 'By means of the apparatus of the invention is is possible to train different groups of muscles of the body by utilizing the various different exercises possible.

The invention will be further illustrated, by way of example, with reference to the accompanying drawings, in which:

FIGS. 11 and 12 are enlarged fragmentary views showing constructional details of the apparatus of the invention. 7 I

The apparatus shown in FIG. 1 is built up on a base orframework 1, and is preferably constructed of steel tubes. Twoplatforms 3 are pivotally connected to theframework 1 by axle 2. Theplatforms 3 are movably and adjustably interconnected by means ofadjustable cords 5, a crossbar l0, and a supportingmember 7,8 adjustable in length. The'supportingmember 7,8, is located between theplatforms 3 and is retained in different desired positions by means of adjustable supportingstays 12. Thecrossbar 10 is detachably pivotally connected at 9 to the supportingmember 7,8, viarevolvable bolt 17 in revolvable and rockable manner.

Thecords 5 are removably attached to theplatforms 3 by means of hooks 4 which pass through lugs fixed to the underside ofhandlebars 14. In this manner, the cords or hooks cannot fall out in training. Nevertheless, they may be easily removed when the apparatus is to be disassembled or is to be altered for other exercises. The supportingstays 12 can be fixed in the same manner.

The supportingmember 7,8 is pivotally connected to theframework 1 byaxle 6. Theaxle 6 is rotatably located in theframework 1, and mounted thereon by means of anangle iron 15, fixed to the framework and equipped withlugs 16 that can be bent inwards (shown in detail in FIGS. 11 and 12).

Theframework 1 can be made in two parts (as shown in the drawings) or as a single piece. Thecords 5, and the supportingstays 12, may be made of nylon or chain-cable, etc. and in known manner they can be made adjustable by means of lock-blocks or hooks etc. Theplatforms 3 are each equipped at their free end with ahandlebar 14 for different arm-and body exercises. The supportingmember 7,8, can be adjusted in length and fixed by means of abolt. Thecrossbar 10 can be provided withmovable collars 13 in order to fix thecords 5 thereto or to' act as fastening elements for rolling blocks or castors, according to requirements.

FIG. 2 shows the apparatus of the invention in a collapsed condition when not in use. The crossbar l and part of the supportingmember 8 may be positioned on opposite sides of theframework 1.

FIG. 3 shows the apparatus of the invention being utilized for a body exercise.

The apparatus as shown in FIG. 4 may be used as a rowing apparatus, in which case the supportingmember 8 is equipped with a foot-support 11. Thecollars 13 on thecrossbar 10 are then equipped with apulley arrangement 21 and thecords 20 pass from the operator via thecrossbar 10, to a rolling-seat 18 equipped with wheels. On the back edge thereof, the seat may have an elevated back section, or asuitable belt 19 which is fastened to the seat 18 to act to counteract the forces produced during the exercise. In this way the participant is prevented from sliding on the seat. It is up to the participant how much force he wants to apply in the rowing action since the resistance offered depends on the foot-force applied.

The same cords and crossbar may be used for different exercises, e.g. when the apparatus is hung up on a wall (FIG. in this case with aconnected cord 23.

The seat 18 may also be used for other exercises. It is possible to repose on the seat, and in the traditional way to roll with same forward and back. When the apparatus is used as a gymnastic apparatus, the cords can be freed from contact with the platforms, and be equipped with a crossbar in the same way as when it is used as a swing. When the apparatus is used as a swing, the cords are provided with a seat 24 (FIG. 6). The cords run then through castors, and they are equipped with handle-bars, so that the participant can raise and lower the body.

FIGS. 7,8, 9 and show various forms of exercise possible with the apparatus of the invention.

All cords and stays, as well as the supporting member are adjustable in length. It is possible to rotate the crossbar in the horizontal as well as the vertical direction, and it is removably connected to the supporting member.
