INVALID'S CHAIR Filed Aug. 12, 1966 United States Patent 3,363,939 INVALIDS CHAIR Eshcol S. Gross, 3320 /2 N. Delmar Ave., South San Gabriel, Calif. 91777 Filed Aug. 12, 1966, Ser. No. 572,044 Claims. (Cl. 297116) ABSTRACT OF THE DISCLOSURE This chair has arm rests which are pivotally secured to the back of the chair so that they can be rotated into an inoperative position. It also has bridge supporting members at each side of the chair. Each bridge supporting member has a bridge which is normally in a vertical position and which can be moved to a horizontal position when the arm rests are in inoperative position. The back of the chair is pivoted near its lower edge so that it can be rotated into a horizontal position.

This invention relates to furniture, and more particularly, to that piece of furniture known as a chair, and still more particularly, to a chair especially designed for use by invalids.

While there are any number of good invalid chairs on the market, so far as is known, not one of them embodies construction that permits the back to be placed in a horizontal position and the arms to be folded downward in order that the chair can be converted into a gurney for ease in moving a person from a bed to the chair.

It is, therefore, the principal object of this invention to provide an invalids chair of the character herein described, that has both folding back and arms that will permit the chair to be converted into a cot or stretcher.

Another object of this invention is to provide an invalids chair of the character herein described that contains a minimum number of parts of simple construction that will not bind or become inoperative.

Still another object of this invention is to provide an invalids chair of lhe character described that may be constructed of any desired material and/or combinations of material and equipped with wheels and brakes, if it is so desired, without affecting the basic structure of the invention.

Other and further objects and advantages of this invention will come to mind as the reading of the description of its construction proceeds and the appended drawing is examined.

In the drawing:

FIG. 1 is a front view of this invention of an invalids chair.

FIG. 2 is a side view of this invention of an invalids chair with the arms shown in a folded position in dash lines.

IG. 3 is a top view of this invention of an invalids chair.

FIG. 4 is a pictorial view of this invention of an invalids chair with one arm and the back shown in a horizontal position in dash lines.

In the drawing, like parts are indicated throughout the several views by means of like reference numbers.

This invention of an invalids chair comprises four vertically disposed supporting legs 11 which may or may not be provided with supporting wheels. Each leg 11 has its upper end suitably secured to one end of a laterally disposed rail 12. There are obviously two rails, only the front one is shown in the drawing, the rails being in equal and parallel spaced relation to one another A back 13, that is a solid panel, is swingably secured at each side of the chair at the intersection of the upper end of one of the aforesaid legs and one end of one of the Patented Jan. 16, 1968 aforesaid rails 12. This point of attachment of the back to the chair is indicated in the drawing by the reference number 14.

A rectangular member, which I personally call a bridge 15, is located on each side of the chair between two of the aforesaid legs 11, as one can clearly see by looking at the drawing. Here it is also seen in FIGURES l and 4 that the lower edge of each bridge 15 terminates in an upturned inverted U-shaped member 16 that hooks over the top of the longitudinal member which is connected at 7 each end to the upper end of one of the legs 11. Each aforesaid bridge 15 has its U-shaped member 16 normally resting in the bottom of the bridge enclosure 17 except when the bridge is placed in the horizontal position shown in dash lines in FIGURE 4 of the drawing. An arm rest 18, that is L-shaped when viewed from the side, has its front end terminating in a hook 19 while the rear end projects back beyond the aforesaid back 13 of this invention where the arm rest is provided with an opening through which extends one end of the laterally disposed, U-shaped rod 20 which has each outer end inwardly turned and terminating in a recess in a lug 21, or its equivalent. The lug 21 is suitably secured to, or built into, the aforesaid back 13 of the chair. This unique construction permits the aforesaid arm rest 18 to be swung downward out of the way of the rest of the chair when it is so desired to place a person in the chair or to remove him from it. There are obviously two arm rests 18, one on each side of the chair. They are adapted to fit over the top of the upper edge 22 of the aforesaid bridge 15 when the bridge is in a vertical position. Looking at FIG- URE 4 of the drawing again, it will be seen that the aforesaid hook 19 of each arm rest 18 is adapted to engage the front edge 23 of the seat 24, thus firmly holding the arm rest in the normal position shown in the often mentioned FIGURE 4 of the drawing.

This invention of an invalids chair may be equipped with a front bridge panel of similar construction as that of the two side bridges although this feature of the invention is not shown in any of the four views for reasons of clarity.

The way in which this invention can have its bridges 15. extended horizontally and its back let down to a horizontal position is quite clear when one examines FIGURE 4 of the drawing where only one of the bridges 15 is shown in the just mentioned horizontal position. Obviously, the arm rest 18 must be swung back out of the way before the desired bridge can be rotated horizontally. Obviously, the seat 24 must be provided with a recess in each side thereof in order to permit each of the bridges to fit into the normal vertical position between the legs 11 of the chair and to be swung into the previously mentioned horizontal position when it is desired to move a person in and out of the chair from or to a bed.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to make all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention of an invalids chair, what I claim as new and desire to secure by Letters Patent is:

1. An invalids chair of the character described, comprising four vertically disposed legs suitably secured to two laterally disposed spaced and parallel rails supporting a seat; and a back that is normally in a vertical position, the said back being swingably secured at the lower edge and at each side thereof to one of the said rails; and arm rests on each side thereof which arm rests are pivotally mounted to permit movement to an inoperative position; and a solid rectangular bridge that is located directly under each of the said arm rests, each bridge having means for securement to the side of the chair to extend outwardly in a horizontal position when so desired.

2. The invention of claim 1, wherein each of the said arm rests is an L-shaped member having its front end terminating in a hook adapted to hook onto the front edge of the said seat when the said arm rests are in normal position for use.

3. The invention of claim 2, wherein each of the said arm rests extends back beyond the said back of the said chair, the rear end of each arm rest having an opening therethrough, through which extends one end of a laterally disposed U-shaped rod that has its outer end inwardly turned and terminating in a recess in a lug or its equivalent that is suitably secured to, or built into the said back of the said chair.

4. The invention of claim 3, wherein each of the said rectangular bridges, which are normally in a vertical position between the said legs of the said chair, is provided with an integrally formed inverted U-shaped member adapted to hook over the top of a longitudinal member 4: that is connected to the upper end of the said legs when it is desired to place the said bridge in a horizontal position after the arm rests have been swung back out of the way.

5. The invention of claim 4, wherein the said invalids chair is provided with a bridge enclosure on each side thereof in which the lower end of the said bridge rests when in the normal vertical position.
