Application March 9, 1949, Serial No. 80,351

1 Claim.

It is further understood that the chair may be equipped with a brake to lock the same against rolling when desired, etc.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a prospective view of an invalid chair embodying the features of my invention.

Figure 2 is a sectional side elevation of th same, the section being indicated by line 2-2 of Figure 3.

Figure 3 is a top plan view of the chair partly in section as indicated by line 3-3 of Figure 2.

Figure 4 a cross sectional view of the same, the section being indicated by line 4-4 of Figure 2.

Figure 5 another cross sectional view of the chair, the section being indicated by line 5-5 of Figure 2; and

Figure 6 is a detail sectional view of the seat corner illustrating a lock mechanism for an arm of said chair, the section being indicated by line 6-6 of Figure 2.

Referring by characters to the drawings, l indicates a tubular rectangular floor frame having mounted on each corner standard caster wheels 2 .2-

The rear stretch of the floor frame has extended upwardly from its side stretches and end a triangular bracket 3, which bracket supports a centrally disposed integral threaded sleeve 4. The sleeve carries a spindle 5 in threaded adjustable connection with the sleeve and the upper end of said spindle has mounted thereon any type of seat 6, the back of which seat, in this instance, has pivoted thereto companion arms 1-! having downturned struts that are confined to the seat frame by pivoted dogs 8-8, and as indicated in dotted lines of Figure 4, one of said arms, for convenience, may carry a narrow writing board I for the convenience of the patient.

The front stretch of the floor frame has vertically extended therefrom a steering tube 9,

which tube is suitably braced by an obliquely disposed U shaped strut It that is connected to the upper portion of the steering tube and the legs thereof are secured to the side stretches of the floor frame I.

The upper end of the steering tube has socketed therein an adjustable handle bar 1 I.

It will be noted that the seat spindle 5 may be adjusted up or down in the sleeve and locked, if desired, in any adjusted position by a hand actuated bolt 4'. v

I may in some instances provide the floor frame with a foot rest, not shown.

From the foregoing description, it is apparent that when the patient desires to remove the arms for the purpose of conveniently entering the seat, they may be swung backwardly upon their pivots by first disconnecting pivoted dogs 8 from the rear portion of the seat frame, and after the patient is comfortably seated, the arms may be swung back into their locked positions.

The patient thus seated with the feet upon the floor may readily move the chair into any desired position and properly steer the same. It is also apparent when the patients desire exercise, they may stand upright upon the floor within the confines of the frame I, and being supported with their hands upon the handle bar I3, may readily walk with the supporting aid of said handle bar.

Thus, the patient equipped with this chair may personally obtain all the conveniences that would ordinarily require the assistance of a nurse. It being understood that this invalid chair is of such proportions that it may readily be manipulated in small quarters if desired.

The outside frame of the chair seat is a little higher to hold the cushion or padding from sliding off the chair.

I claim:

An invalid chair comprising a tubular rectangular floor frame, caster Wheels secured to the frame corners, a threaded sleeve, a supporting bracket for the sleeve having downwardly inclined struts connecting the sides and rear stretches of the frame, a seat having a threaded spindle 3 4 mounted in the sleeve, a vertically positioned REFERENCES CITED steering tube extending upwardly from the from The following references are of record in the stretch of said frame, the same having an obfile of this patent:
