MULTIPURPOSE INVALID CHAIR Filed Nov. 26, 1962 4 Sheets-Sheet 2 Mair/P R Hubbard INVENTOR.

moi Q W United States Patent 3,213,467 MULTIPURPOSE INVALID CHAIR Mattie P. Hubbard, 205 N. Daugherty St, Eastland, Tex. Filed Nov. 26, 1962, Ser. No. 240,036 2 Claims. (Cl. 4-135) The present invention relates to an improved multipurpose invalid chair expressly designed and constructed to effectually fulfill the needs, preferences and abilities of the sick or aged occupant and which is appropriately adapted for use in a hospital, a nursing home or ones private home.

One objective is to take full advantage of limited available space when, as in the hospital or nursing home, space may be and often is at a premium. As will be hereinafter made clearly apparent the chair herein disclosed and despite the many facilities available therein is nevertheless compact and practical and well serves the purposes for which it is intended.

In order that the patient may enjoy the maximum use of the chair and its readily available facilities the latter are so constructed and arranged that compactness and convenience is ideally achieved. To this end, all of the component parts are systematically and efficiently c0- ordinated for the individual needs of the patient and for optimum comfort and acceptability to the patient.

Another significant factor has to do with the adoption and use of carefully planned easy-to-use appliances which serve to make the patient more independent and effectually geared to his or her needs. Maximum function therefore means being able to embody in a single successful chair construction the ready-to-use needs of the patient, not overlooking, of course, insured safety and practical conveniences for the nurse or other person assisting the patient.

It will also be appreciated that the improved chair is capable of being acceptably used by a guest when it is not needed by the patient. The construction is such that a compressibly resilient upholstered seat cushion is provided, said cushion serving to cover over and conceal a commode opening, seat ring and lid for the latter when not necessary for use by the patient. In this connection it is to be pointed out that the chair also has an upholstered backrest and armrests. Consequently, it constitutes ideal upholstered furniture for the user and, inasmuch as the upholstering material is waterproof (washable plastic material) it contributes further to the usefulness of the chair in that it facilitates washing, cleaning and drying.

Another improvement resides in a highly serviceable invalid or equivalent chair which not only offers restroom service but includes and features a detachably and swingably mounted tray which is such in construction and location that it enables the occupant of the chair to use it as a table when partaking of a meal and which, in addition, is usable as a desk for reading and writing purposes.

A further improvement resides in the adoption and use in a multipurpose invalid-type chair having a rack on the back for a towel or a washcloth. Further, a handlebar is also provided on the back so that the nurse or other attendant may handle and move the chair and occupant from place to place.

Then, too, the cabinet-type base meansof the chair is augmented by the incorporation therein of side cabinets which are shelved or otherwise constructed and provided with doors and which provide practical available space for storage of readily accessible body and face powder, toilet 3,213,467 Patented Oct. 26, 1965 tissue, soap, toothpaste, toothbrush, medicines, and the like.

It is also within the purview of the concept to provide a projectible and retractible slide at the bottom of the base which is so constructed and arranged that it constitutes a highly satisfactory footrest.

In carrying out a preferred embodiment of the unique chair a correspondingly unique frame structure characterized by rigid aluminum or equivalent tubing is utilized with a view toward expediting the manufacture and assembling of the component parts which go to make up the finished chair.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a view in perspective of an invalid chair constructed in accordance with the present invention and showing the featured improvements; namely, the tray, one auxiliary side compartment and the footrest extended to a useful position;

FIGURE 2 is a view also in perspective and similar to FIGURE 1 but observing the opposite or lefthand side thereof (left in relation to FIGURE 1) and which illustrates the footboard retracted, the seat cushion removed and the table-forming tray detached and suspended in an out-of-the-way position on the back of the chair, parts being broken away and other parts appearing in section;

FIGURE 3 is an exploded perspective view with the illustrated parts on an enlarged scale and showing the particular form and construction thereof;

FIGURE 4 is a view on a larger scale (compared to FIGURES 1 and 2) of the chair observing the same in a direction from the back thereof (left to right in FIGURE 2) and wherein parts are broken away for convenience of illustration and other parts are shown in section to emphasize the construction and the availability of the waste jar or receptacle;

FIGURE 5 is a section at right angles to FIGURE 4 with parts appearing in section and elevation taken on the plane of the vertical section line 5-5 of FIGURE 4;

FIGURE 6 is a view in perspective of the light weight skeleton aluminum frame structure which in the finished structure is completely enclosed and concealed;

FIGURE 7 is an enlarged fragmentary detail sectional and elevational view taken on the plane of the line 77 of FIGURE 5;

FIGURE 8 is an enlarged sectional and elevational detail View taken on the plane of theline 88 of FIGURE 1;

FIGURE 9 is an enlarged view in elevation and section and shown in perspective and which serves to show the structural details supporting and retaining the waste jar;

FIGURE 10 is an enlarged detail section taken on the plane of the irregular section line 1010 of FIGURE 4; and

FIGURE 11 is a section on the line 11--11 of FIG- URE 6.

Considering the chair first as a finished ready-to-use article of furniture it will be noted that the base means, construed as a unit, is denoted by thenumeral 14 and is of rectangular hollow box-like form. By using appropriate panels and joining the same together in a unified manner it will be noted that there is a horizontal bottom wall 16 (see FIGS. 4 and 5 in particular) and this has its marginal edges joined with a vertical rear orback wall 18, a verticalfront wall 20, side walls 22 (at the right in FIGURE 1) and 24 (at the left in FIGURE 2). These side walls are provided with suitably enlargedopenings 26 which in conjunction with the built-inwalls 28 define themain commode compartment 30 and the side auxiliary compartments both denoted by thenumeral 32. These side compartments are provided with suitable interior shelves 34 (FIG. 1) and hingedly mountedclosing doors 36. The side compartments or auxiliary compartments serve for convenient storage of small toilet articles and the like, for example, face and body powder, toilet tissue, soap, toothpaste, toothbrush, medicines and so on (not shown). The main commode compartment is accessible by way of a hinged panel or an equivalent openable andclosable door 38 in the manner illustrated in FIG. 5. Suitable spaced guide members 40 (FIGS. 4 and provide supporting tracks for an extensible andretractible panel 42 having a strip ofmolding 44 across the front edge and which functions as a convenient footrest or shelf as shown in full lines in FIG. 1 and in full and dotted lines in FIG. 5

In a plane below the level of the guide tracks orrails 40 andfootrest 42 swivelly mounted fixtures serve to accommodatingly support casters orrollers 46.

Referring now with greater particularity to thetop wall 48, this wall is fixed to the walls therebeneath and constitutes a seat member. As such it constitutes a foundation for the attachable anddetachable seat cushion 58 which fits thereon and covers the top surface thereof in the manner shown best in FIG. 1. This cushion is of appropriate compressibly resilient construction (not detailed) and is covered with waterproof washable upholstering material 52. To assist in holding the cushion in place it is provided on marginal portions withholddown tabs 54 having snap fasteners which are secured to appropriate snap fasteners (not detailed) on the panel orwall 48. When the cushion is removed it serves to uncover and expose component parts of the toilet or commode facilities. An opening 56 (FIG. 5) is provided in the seat board ormember 48 and is encircled or surrounded by a fixedannular member 58 which constitutes a toilet seat, and the central opening of which is normally covered by an appropriate lid orcover 60. The waste jar or receptacle, which is readily insertable and removable in relation to themain compartment 30, is denoted by thenumeral 62 and is provided at its open upper end with a supportingflange 63 which is slidingly suspended on ledge means 64 (FIG. 9) provided therefor in the supporting cleats orrails 66. Thejar 62 may be put in position or removed conveniently by way of the closure panel ordoor 38. It will be note-d in FIG. 9 that on one side wall the jar is provided with a radialoutstanding handle 68 the free end 70 of which may be engaged behind a pivoted retaininglatch 72 whereby to insure that the jar when lined up with the opening 56 will remain in this position until the user desires to have it removed by an attendant.

With reference now to the rearward portion of the base unit or means 14 it will be noted that thenumeral 74 designates, generally speaking, an inclined backrest. The backrest is appropriately padded or otherwise upholstered and has its lower end resting atop the base unit, the upholstery material or covering 76 being waterproof and of appropriate color. With this backrest and seat cushion supported on and in conjunction with base means 14 the overall chair resembles a conventional-type upholstered chair. If desired, horizontal spacedparallel armrests 78 are provided. The armrests are of composite construction and, for example, the waterproof plastic covering is denoted at 80 (FIG. 5), the padding at 82 and the armrest proper is denoted at 84, this being a component of the L-shapedtubular metal unit 86. Thevertical leg 88 is appropriately fixed to the base unit and the rearward end of thearmrest 84 is connected by a clevis H aframe member 134 provided therefor as at 116.

98 to the backrest, more particularly, to the frame means which is embodied in the backrest.

Before describing the specially fabricated aluminum frame means (FIG. 6) other facilities will be set forth. To this end attention is directed to thenumeral 92 which designates an attachable and detachable component part which is convertible in that it serves as a temporary table, also a desk. To accomplish this a U-shaped member 94 (FIG. 5) is provided, said member including abight portion 96 andlimbs 98 which are suitably attached to the bottom of a rim-equipped tray 1110. The tray spans the limbs and is attached to the bight portion in any appropriate manner and it is of a width and length proportional with the parts of the overall chair with which it is cooperable. This tray when in the horizontal position seen, for example, in FIG. 1 is employed, at least primarily so at mealtime. At other times the tray or means 92 can be tilted (FIGURE 5) or to an interven ing position (not shown) to serve as a bookrest or to function as a desk. It should be noted that theside limbs 98 are provided exteriorly with stays. Eachstay 102 is pivoted at 104 and is made of springy metal, the free end thereof being provided with aknob 106 which has a detent which is engageable in a keeper hole provided therefor in the limb when the stay is not being employed for elevating and retaining the tray. When not in use the stays may be swung down and the detent 108 (see FIG. 8) may be engaged in thekeeper hole 110 provided therefore. In other words, these stays serve as props and as a matter of fact they also have the additional function of retainers in the manner illustrated in FIG-URE 8. With reference to this figure it will seen that the tubular limb is fitted telescopically over ashort adapter tube 112 which is pivotally mounted at 114 on In other words the detent in this arrangement extends through thekeeper hole 118 and consequently the sleeve-like limb is fitted over and retained on theadapter 112. When it is desired to bodily detach and store the tray means in an out-of-the-way position this can be done by releasing thedetent 108 by way of the grip orknob 106. It should be noted that FIGURE 2 compared to FIGURE 1 shows the tray means 92 stored in an out-of-the-way position on the back of the chair. This is accomplished by bodily detaching the tray means 92 from theadapter members 112 and then hanging or suspending the tray on hanger hooks 120 which are paired and provided therefor on the rear of the backrest. FIGURE 4 brings out the manner in which the rim of the tray is hung on the hook at the left. It is also desirable to providesafety latches 122 which are so constructed and arranged that they may be engaged with the dependinglimbs 98 in the manner illustrated in FIG. 4. The limbs have keeper holes to accommodate the lateraly directed end portions of therespective latches 122.

The numeral 124 designates a U-shaped handle bar which is connected at its end portions to achannel member 126 fitted over thebight portion 128 of the invertedU-shaped frame member 138 of the interior frame structure illustrated in FIGURE 6. Below this handle (which is used by the attendant to push the chair from place to place) there is a similar but largerU-shaped bar member 131 which constitutes a towel rack and which has itsend portions 132 suitably fastened to the dependingtubular legs 134 of theU-shaped frame member 130. These same legs carry the aforemetnioned tray hanger hooks 120. If desired thehooks 120 may be provided withplastic sleeves 133 which function as protectors and which facilitate ready and retained suspension of thetray 100 when stored. A further facility is offered, for example, the safety belt, one portion of which is denoted at 135 and is anchored in place at 137. This belt may be of any suitable construction and the ends may be appropriately attached to frame components in any practical or desired manner.

As is perhaps evident from the preceding description the base and backrest means can best be utilized if employed in conjunction with the tubular metal (aluminum tubing) frame structure illustrated in FIG. 6. With reference to this figure it will beevident that theaforementioned legs 134 are connected with ahorizontal cross brace 136 spaced above the level of the horizontal seatpanel supporting members 138. Thesemembers 138 in turn are connected to dependingvertical legs 140 which are in turn joined with horizontal reinforcingtubes 142. To be more specific the rearward or lefthand end portion of each horizontal tube is flattened as at 144 (FIG. 3) and this flattened end is provided with abracket 146 which is opposed to and bolted to anear 148 on aplug 150 which is fitted telescopically into the lower end of theleg 134, the latter being bolted in place as denoted at 152 in FIG. 7. The means for connecting the lugs orears 146 and 1 48 together preferably comprises a headed screw-threaded fastener 154 (FIG. 7) which is threaded into a socket provided therefor in a cooperating end portion of arigidifying brace 156. This brace is horizontally disposed and is secured by aclip 158 to theframe member 136, (see FIGURES 4, 5 and 6 in particular). A suitable front orcross member 168 is arranged between the dependingfront legs 140 to substantially complete the frame part of the base unit. It should be noted in FIG- URE 6 that the forward end portions of theframe members 138 are provided withsleeves 170 having dependingfingers 172 which straddle diametrically opposite sides of the upper ends of thelegs 140 and are fastened thereto.v With further reference to the lower end portions of the vertical legs 140 (see FIG. 3) it will be noted that the terminal end is suitably recessed or shaped as at 174 to accommodate aplug 176 which has a screw-threadedsocket 178 to accommodate the screw-threaded headedfastener 180. This type of connecting means is employed in several situations as illustrated, for example, in FIG-URES 7 and 11.

The improved chair is practical and constitutes an aid in caring for the semi-convalescent patient. It offers mobility when walking has become a problem and yet is not as heavy and unwieldy as a wheel-chair. In the adjustable tray the patient has immediately available facilities for eating, writing and reading in the three adjustable positions of the tray.

The comfort of an adjustable footrest is an attractive feature and will mean much to one who must spend long hours in a sitting position. To avoid the possibility of the patient falling from the chair an adjustable seat belt is provided. The belt will also prevent one from leaving the chair when the mentality is impaired.

Sanitary facilities are provided in the removable waste jar stored in the base of the chair in a ready position. The foam rubber cushion is easily removed thus making ready use of the jar underneath. The jar may be removed through door in back of chair base. For added comfort the foam rubber padding in chair back is form fitting deepening from top to bottom of back.

It is believed that a careful consideration of the statement of the invention, the specifically enumerated objectives and description of the details in conjunction with the views of the drawings will enable the reader to obtain a clear and comprehensive understanding of the invention, the features and advantages and the preferred manner of using the same. Accordingly, a more extended description is regarded as unnecessary.
