WILLIAM DIEMEB, OF TOLEDO, OHIO, ASSIGNOR TO GENDRON WHEEL COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

\ INVALIDS CHAIR.

Specification of Letters Patent.

Patented Oct. 1, 1912.

To all whom it may concern: Be it known that I, WVILLIAM DIEMER, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful improvements in Invalids Chairs, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to wheel chairsbeing particularly designed for use in sick rooms and in hospitals and it is one of the objects of the invention to obtain a construction which may be folded when not 'in use and which will stand without other support in this folded position;

In the drawings,Figure 1 is a perspec the View of the chair in the position for use; Fig. 2 is a similar view showing the collapsed position; Fig. 3 is a perspective view of a. portion of the seat and back; and Fig. i is a cross section therethrough.

A is a rear frame, B the forward frame, C a horizontal frame, D a seat and E an arm section of a. pivotally connected foldable parallelogram frame. F is a diagonal joint brace rod for holding said frame normally in rectangular position and which extends from the forward frame B to the arm rests, there being preferably one of these braces on each side of the chair.

The frame A- is an inverted U-shaped member having the cross bar A which extends in rear of the chair and constitutes a handle for moving the same. The lower ends of the frame A are bent to extend rearward but are normally held above the floor by rear legs Gr. These rear legs are preferably formed by rearward extensions of the horizontal frame C, being curved downward and provided with casters H for engaging the floor. The forward frame B is also provided with casters H.

Vvhen the chair is to be collapsed the braces F which are provided with rule joint hinges F are broken upward to permit the folding of the frame, which movement will project the rear supporting legs G laterally forward to a point. beyond the center of gravity of the folded structure. The rearwardly extending lower ends A of the frame A will then rest upon. the floor and as they bear in rear of the center of gravity of the folded structure the latter will be afforded a suitable support, so that it stands alone.

. To adapt the chair for use in asick room or hospital it is preferably provided with a' double seat the upper member D being small space and will stand upright without other support.

' What I claim as my invention is:

1. In a chair, the combination with a foldable frame, of supporting legs extending from the horizontal member of said frame normally in rear thereof and projected laterally forward of the center of gravity of said frame in the folded. position, and rearward extensions on the vertical member of said frame normally out of contact with the floor and forming a rear support in the folded position.

2. In a chair, the combination with a fold able parallelogram frame including a vertically extending rear frame member and a horizontal member, of rear supporting legs formed as rearward extensions of said horizontal member adapted in the folded position to project laterally forward of the center of gravity, and rearward extensions on the vertical member of said frame normally out of contact with the floor and in the folded position constituting a rear support.

3. In a chair, the combination with a collapsible parallelogram frame including vertically extending rear member and :1V

horizontally extending member, of rearward and downward extensions of said horizontal member constituting supporting legs and adapted to be projected laterally forward of the center of gravity in the folded position of parts, and downward and rearward extensions of said vertical member normrdl J out of contact with the floor and forming a rear support in the folded position.

4. In a chair, the combination with a collapsible parallelogram frame including rear vertically extending member ofinverted U-shaped form, the upper portion and cross bar forming a handle and the lower the vertical fra'lne together constituting a' ends being extended downward and rearward, a horizontal member forming a portion of said frame having rearward and downward extensions forming rear supporting legs and in the folded position extending forward of the center of gravity, said supporting legs and rearward extenslons of suitable support for t e folded chair. 10 In testimon whereof I afiix my signature in presence 0 two witnesses.
