INVENTOR.

ADAM E. GAMON ATTORNEYS United States Patent ABSTRACT OF THE -DISCLOSURE A legless chair having a seat joined to upstanding side and back members from which members depends a skirt the lower end of which flares outwardly and extends below the level of the seat to provide a wide and stable base for supporting the chair on a bed or the like.

This invention relates to a legless chair construction and more particularly to a chair which is especially adapted for use in supporting a patient on a bed in an upright sitting position, although the chair, if desired, may be supported on any one of a number of other kinds of supports.

A person who, for reasons of health or otherwise, must remain in bed over a period of several or more days will suffer a relaxation of his cardiovascular system. Upon sitting up, the blood will flow downwardly by gravity through the relaxed vessels, frequently resulting in faintness. Physicians seek to prevent cardiovascular relaxation by having patients assume an upright position gradually, and frequently have a patient sit on the edge of his bed with his feet and legs dangling without touching the floor. Sitting in such a position becomes uncomfortable rather quickly because of the strain imposed on a patients back. Moreover, older persons have a tendency to fall to one side or the other, or forwardly, not only because they may be more unstable, but because of the faintness which may result from cardiovascular relaxation. If faintness should occur when a patient is sitting on the edge of his bed, a fall quite easily may result. Accordingly, it has been the usual practice heretofore to prop pillows behind and around the patient in an attempt to provide some support, but such a solution is not always effective inasmuch as the pillows are quite yieldable and are subject to sliding.

An object of this invention is to provide a chair which may be used to support a patient in comfort and with safety on the edge of a bed so as to permit the patient to obtain the benefits of sitting in an erect position.

Another object of the invention is to provide a chair of the character referred to and which is strong, light in weight, and inexpensive to manufacture.

A further object of the invention is to provide such a chair as has been described and which is capable of being securely fastened either to a bed or to some other kind of support.

Another object of the invention is to provide a chair which lends itself to removable connection to a wheeled frame, thereby enabling the chair to be used in the same manner as a wheel chair.

Other objects and advantages of the invention will be pointed out specifically or will become apparent from the following description when it is considered in conjunction with the appended claims and the accompanying drawings, in which:

FIGURE 1 is a fragmentary perspective view, partly in section, illustrating a chair constructed in accordance with the invention and secured to a bed;

FIGURE 2 is a fragmentary sectional view of the chair;

FIGURE 3 is a fragmentary, front elevational and partly sectional view of the chair; and

FIGURE 4 is a view similar to FIGURE 1, but illustrating the chair supported on a Wheeled frame.

3,335,434 Patented Aug. 15, 1967 A chair constructed in accordance with the invention preferably is molded from a suitable plastic material such as styrene or the like and comprises a seat member 1 which preferably is formed with a concavo-convex upper surface, as is best illustrated in FIGURE 2, so as to provide a comfortable seat. At its rear edge, the seat merges smoothly with an upwardly and rearwardly inclined back member 2. The side edges of the seat member and the side edges of the back member merge smoothly with upstanding side members 3 and 4. To the upper edges of the side members 3 and 4 are joined outwardly extending, generally horizontal flanges 5 and 6, respectively, which form arm rests having substantially flat surfaces which, adjacent their rear ends, extend upwardly and merge with the side edges of the back member 2. To the outer edges of the flanges 6 is integrally joined a depending flange or skirt having opposite sides 7 and 8 which merge smoothly with a rear portion 9 so as to form an enclosure for the sides and back of the chair. At the lower ends of the skirt portions 7, 8 and 9 are outwardly flared portions 7a, 8a and 9a which terminate in a beaded or reinforced rim 10 lying in a substantially horizontal plane at a level just below the level of the seat 1. The rim 10 thus provides a large area base so as to form a stable support for the chair. To the forward edge of the arm rests 5 and 6 are joined downwardly extending skirt portions 5a and 6a, thereby providing a smooth and unitary construction.

Joined to the forward end of the seat member 1 is a downwardly extending flange 11 which terminates in a reversely turned lip 12, the lower surface of which preferably is located in the, same plane as the terminal edges of the skirt portions. The flange 11 forms a support for the forward edge of the chair seat and minimizes the risk of forward tilting of the chair.

The upper surface of the seat 1 preferably is pebbled or otherwise roughened so as to minimize the risk that a patient may slide out of the seat. If desired, a cushion 14 may be included so as to provide a comfortable seat.

A chair constructed in accordance with the invention is adapted to be fastened on a bed 15 and in such manner as to permit the occupant of the chair to dangle his feet over the edge of the bed. Means for securing the chair to the bed comprises a flexible strap 16 having a buckle 17 at one end and being of such length as to enable the belt to extend completely around the mattress 18 of the bed. Openings 19 and 20 are provided in the chair members 9 and 11, respectively, so as to permit the belt to extend through the chair below the level of the seat 1.

As a further precaution against the possibility of a patients falling out of the chair, the side members 3 and 4 may be provided with openings 21 and 22, respectively, through which the opposite ends of a safety belt 23 (see FIGURE 4) may extend, the central portion of the belt extending around and beneath the seat member 1. The belt 23 may have a buckle 24 at one end by means of which the safety belt may be drawn snugly about the body of the patient.

In many instances it may be desirable to support a tray 25 or the like on the arms of the chair. The tray may comprise a generally flat member 26 of such length as to span the arm rests 5 and 6, as is indicated in FIG- URE 1. To the lower surface of the member 26 may be fixed a pair of mounting arms 27 which are spaced apart a distance corresponding to the spacing between the arm rests and which may be removably accommodated in openings 28 formed in the skirts 5a and 6a. Also fixed to the lower surface of the tray 26 is a pair of spaced apart brackets 29 through each of which slideably extends an anchor pin 30 that is adapted to be accommodated in any one of a plurality of openings 31 provided in the adjacent skirt portion 7 or 8 so as adjustably to secure the tray to the chair.

To facilitate handling of the chair, the skirt portions 7 and 8 are provided with hand openings 32 and a similar opening 33 may be provided in the skirt portion 9.

A chair constructed in accordance with the invention also is adapted to be supported on structures other than beds. For example, the chair may be mounted on a wheeled support 35 comprising a framework formed of generally horizontal frame members 36 on which the lower edges of the chair may rest. The front frame member 36 may be accommodated between the seat 1 and the lip 12, as is indicated in FIGURE 4. Secured to and depending from the upper frame members 36 are uprights 37 at the front of the frame and a similar upright (not shown) at the rear of the frame. Spanning the front uprights 37 is an axle 38 on which is journalled a pair of wheels 39. Swivelly mounted on the rear upright is a rear wheel 40. Suitable braces 41 interconnect the front and rear uprights to provide the requisite rigidity.

When the chair is supported on the wheel frame 35, the chair may be securely anchored thereto by the strap 16.

Preferably, a foot rest 42 is included and comprises a generally U-shaped frame composed of parallel side bars 43 interconnected by a web member 44 which may be accommodated by the lip 12 of the flange 11. Recesses 44a may be provided in the skirts a and 6a at opposite ends of the flange 11 to accommodate the bars 43. A foot board 45 interconnects the opposite ends of the side bars 43. If desired, the side bars 43 may be formed of two telescoping sections so as to provide for vertical adjustment of the footboard 45. The footrest may be supported by the wheeled frame or, if desired, may be suspended from the lip 12 so as to enable the footrest to be used with the chair when the latter is supported on a bed.

The disclosed embodiment is representative of the presently preferred form of the invention, but is intended to be illustrative rather than definitive thereof. The invention is defined in the claims.
