CHAIR.

Specification of Letters Patent.

Application filed August 4, 1916. Serial No. 113,078.

To all whom it may concern:

Be it known that I, WALTER I. KIRK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain'new and useful Improvement in Chairs, of which the following is a. full, clear, concise, and exact description, referencebeing had to the accompanying drawings, forming a part of this specification.

My invention relates to chairs, and especially to collapsible chairs.

Prominent objects of the invention are to provide a simple and practical construction of collapsible chair; to arrange so that the chair when collapsed shall be very thin; to secure firmness when the chair is in position to be occupied; to arrange to permit the chair to be easily engaged and supported when in a collapsed position; to secure simplicity of construction and reduce the cost of manufacture; and to secure the foregoing and other desirable results in a simple and practical manner.

In the accompanying drawings Figure 1 is a view partly in elevation and partly in vertical section of a collapsible chair embodying my present invention;

Fig. 2 is a similar view of the chair in a collapsed condition supported in position upon a vertical wall or structure;

Fig. 3 is a front elevation of the chair in position to be used; and

Fig. 4 is a plan view of the same.

In the drawings there is shown a chair wherein the back 1 is mounted at the upper ends of members 2 which extend downwardly and form the rear legs 3. A cross member 4 extends between the legs 3. The seat 5 is hinged, as by hinges 6-6, tothe members 2, being conveniently secured to a cross member 7 extending between themembers 2 and forming the rear support for the seat 5. The front legs 8 are hinged, as by hinges 9, to the front of the seat 5. Side braces or arms 10 are pivoted at 11 to the sides of the seat 5 and extended upwardly and rearwardly where they engage pins 12 on the outer sides of the members 2, thus forming braces and connections between the seat and the back. Other side members 15,

are pivoted at 16 to the rear legs 3 and have their other ends provided with slots 17 adapted to engage pins 18 on the front legs 8 and thereby form braces for connecting the front and rear legs.

To collapse the chair the members 15 are elevated so as to disengage them from the pins 18 and then the front legs 8 and seat 5 are swung about the hinge connection between the latter and the member 7. This movement is continued until the seat comes into position against the front of the rear legs 3, after which the front legs are swung upwardly to the position of complete collapse shown in Fig. 2. In such completely collapsed condition the seat 5 is substantially against the rear legs 3, the front legs 8 extend up in a substantially vertical manner upside down, in the rear of the seat 5, and the brace members 15 lie in a substantially vertical position between the seat 5 and the front legs 8. The front legs 8 are set farther away from each other than the rear legs 3, as shown in Fig. 3, and the cross member 20 between the lower ends of the legs 8, is so located as to pass down below the lower ends of the rear legs 3 when the seat 5 and legs 8 are being swung down to collapse the chair. Consequently said cross piece 20, when the chair is collapsed, comes into position in the rear of the back members 2, as shown in Fig. 2. Thus the chair when collapsed has all of its members extending substantially parallel to one another in very close arrangement, occupying very little space. Furthermore, the chair in collapsed condition may very advantageously be sup ported in a vertical condition upon a vertical wall or other member, as shown in Fig. 2. In this condition the lower ends of the legs 3 may be mounted in sockets 21. secured to a wall 22, and the cross member 20 may be inserted between two strips 23 arrangedabove and below said member 20. A catch 24 ivoted to the upper member 23, may hold said member 20 against movement out of the space between said members 23.

In another application of mine executed of even date herewith, Serial No. 113,076, trunks for harps or like instruments, filed August 4, 1916, I show a trunk for a harp or like instrument containing a chair such as disclosed herein, said chair being mounted upon one of the flat side walls of said trunk in the manner shown in Fig. 2 herein. In

said other application I am claiming the arrangement of the trunk and chair or equivalent confining and supporting arrangement, whereas in the present application I am claiming the chair construction alone, the same being usable in connection with a harp trunk or otherwise.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.

What I claim is:

A collapsible chair comprising front and rear legs and a seat hinged. to the rear legs so that said seat may swing downwardly with reference to the rear legs, and also hinged to the front legs so that said front legs may swing upwardly toward said seat, the front legs being separated from one another more widely than the rear legs and being connected by a cross member adapted 20 to pass below the lower ends of the rear legs when the seat and front legs are swung downwardly about their hingedconnections with the rear legs.

In witness whereof, I hereunto subscribe 25 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

Washington, D. G.
