ANTHONY SPERL, OF PITTSBURG, PENNSYLVANIA,

GOLLAPSIBLE CHAIR.

To all. whom it may concern:

Be it known that I, ANTHONY SPERL, a citizen of the United States of America, residing at S. S. Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Collapsible Chairs, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to collapsible chairs and has for its object to provide a chair of such class with means in a manner as hereinafter set forth adapted when the back of the chair is thrown forward to release the seat from the legs whereby the chair will collapse upon the floor to enable a person to readily step over the chair when occasion so requires.

Further objects of the invention are to provide a collapsible chair which is simple in its construction and arrangement, strong, durable, eflicient in its use, conveniently collapsed and inexpensive to manufacture.

With the foregoing and other objects in 5 view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawing wherein like reference characters denote corresponding parts throughout the several views, Figure 1 is a perspective view of a collapsible chair in accordance with this invention and with the chair set up, Fig. 2 is a side elevation of the chair with the back swung forward to release the seat from the back and a pair of supporting legs, Fig. 3 is a side elevation of the chair collapsed, and Fig. 4 is a view illustrating in full lines one of the shiftable looking members for the seat frame, a portion of the latter and a portion of the back being shown in dotted lines.

Referring to the drawing by reference characters, the chair comprises two pairs of supporting legs, the legs of one pair being indicated by the reference characters 1, 2 and the legs of the other pair by the reference characters 3, 4. The legs of each pair cross each other and are pivotally connected together by a tie rod 5, the latter also connecting one pair of legs to the other. Piv- Specificatio'n of Letters Patent.

Serial No. 580,809.

otally connected to the upper ends of the legs 1, 3 is the forward end of a seat consisting of a pair of side rails 6 connected together by horizontally extending slats 7. The upper ends of the legs 2, 4 are pivotally connected to the lower end of the back 8 of the chair by a tie rod 9, over which the forked ends 8 of the sides of the back 8 extend and upon which they rest.

Pivotally connected to each of the side rails 6 of the seat, as at 11 is a seat locking member 10 having its forward end formed with an inwardly extending lug 12 adapted to engage the side rail of the seat whereby the movement of the member 10 in one direction will be arrested. The rear end of the member 10 is notched to provide a hook 13 adapted to engage with the tie rod 9 between the lower end of the back and the upper end of the leg 2 or 4. The function of the members 10 is to connect the seat with the back whereby the chair will be maintained in an upright position. WVhen the members 10 are swung clear of the rod 9 the chair will collapse, as is obvious.

Pivotally connected to the back 8, as at let and also to the side rail 6, as at 15 are the side arms of the chair, each consisting of a pair of sections 16 pivotally connected together, as at 17 Attached to the upper of the sections of each of the arms and secured to the hooked end 13 of the member 10 is a flexible coupling 18, whereby the members 10 are connected to the arms of the chair so that when the back 8 is swung forwardly the flexible coupling 18 will elevate the retaining member 10, releasing the seat and causing the chair to collapse the ends 8 disengaging the back from the seat rod 9 and the bottoms of the legs of each pair moving in opposite directions, so thatthe chair assumes the position shown in Fig. 3 so that one can readily step over the chair when occasion so requires.

That I claim is 1. A collapsible chair comprising a seat frame, foldable supporting means pivotally connected at the forward ends thereof to the forward end of said seat, a foldable back, means for pivotally connecting the foldable back to the rear of said supporting means, a pair of retaining members connected to the rear of the seat and engaging the said means for securing the seat in position thereby maintaining the chair in an upright position, arms connecting the back to the seat,

and means carried by the arms and connected to said members for moving them to released position when the back is swung forwardly thereby causing the chair to collapse.

2. A collapsible chair comprising a seat, foldable supporting legs, means for pivotally connecting the forward end .of said seat to said legs, a back, a tie rod for pivotally connecting the back to said supporting legs, sectional arms connecting the back to the seat, retaining members pivotally connected to the rear end of the seat and engaging the said tie rod for securing the seat in position thereby maintaining the chair in an upright position, and flexible coupling members extending from said arms and connected to said members and adapted when the chair back is swung forwardly to shift the arms from engagement with the tie rod thereby releasing the seat and causing the chair to collapse.

In testimony whereof I afliX my signature in the presence of two witnesses.
