1 Claim.

This invention relates to couch beds of the extensible type, and its principal objects are to provide a couch bed having nestable sections and a back-rest, the nestable sections being relatively movable so that they may be conveniently drawn to. extended position either to form twin beds or a double bed readily accessible without removing the back-rest or any of the parts; to provide a couch bed of the aforesaid type whereinl the nest able sections are provided with releasable locking means designed to prevent accidental release when used as a couch; and to pro-Vide a couch bed which is of simple and economical construction, having but few parts, which is eicient in operation and reliable in use, and which can be manufactured and sold at a relatively low cost.

Further objects of the invention will be apparent from a consideration of the following description and accompanying drawing, wherein:

Fig. l is a front elevation of a couch bed constructed in accordance with the present invention;

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged fragmentary section of the locking mechanism at the right hand side of Fig. 2;

Fig. 4 is a fragmentary elevation showing the relationship of certain parts when the outer section is in extended position; and

Fig. 5 is a section on the line 5-5 of Fig. 4.

The particular embodiment chosen for the purpose of illustration comprises a main or movable outer section l and a stationary inner section designated by the numeral 2 (Fig. 2). The main section l comprises a box-like structure having a front wall t and side walls 5 and E, the rear being open so that the main section may be drawn from about the stationary section. The top of the main section may be of usual construction for supporting a pair of mattresses 9 which provide the seat cushion when the structure is used as a couch. The outer face of the front and side walls may be provided with a suitable finish, such as textile fabric, which may be secured to the lower mattress so as to hold it in position and give the appearance of continuity therewith. The ends of the side walls are provided with vertically extending angle irons l@ whose lower ends are provided with casters or rollers H which support the main section for movement from nested position to extended position.

The stationary section 2 may be of conventional construction having longitudinally and transversely extending frame members i4 and l5 which carry the usual spring supporting structure and are connected to legs or uprights I6 spaced inwardly from the transverse members, as shown more clearly in Fig. 5. Pivotally connected to the front ends of the transverse members l5 are hooks 5 i8 (Figs. 2, 4 and 5) normally arranged above the level of cut-out portions or recesses I9 (Figs. 1 and 4) Yin the legs ll) of the main section, the hooks I3 being disposed to project into the openings I9 when the main section is pulled to extended position, thereby limiting its outward movement, as shown in Figs. 4 and 5. The hooks I8 may be swung upwardly so as to disengage the legs ill, thereby permitting the movable section to be pulled away from the stationary section to provide twin beds. If desired resilient guards 20 (Fig. 5) may be provided on the inner face of the side walls 5 and 6 to prevent the transverse members l5 from binding against the side walls when the two sections are being moved to or from extended position.

A back rest designated by the numeral 22 is supported by the inner section, the back rest comprising a U-shaped member having legs 23 and 24 spaced apart a distance corresponding to that between the rear legs I6 of the inner section, and at least one intermediate longitudinal member 25 which is positioned above the upper surface of the top mattress 9, as shown in Figs. l and 2. The lower ends of the legs 23 and 24 are bolted or otherwise secured to the rear legs iB of the inner section and the upper part of the back rest which projects above the cushions 9 may, if desired, be provided with a suitable covering 28.

In order to hold the sections in nested position and overcome any danger of them becoming accidentally displaced when used as a couch, I provide a centrally disposed releasable latch mechanism (Fig. 3) which is designed so as to hold interlocking parts carried by the respective section in engagement when the sections are in nested position. The latch mechanism comprises an L- shaped member 30 having a vertically extending wing 3l which is secured in any suitable manner to the central part of the inner surface of the front wall 4, and a horizontaly extending wing 32 which projects inwardly at approximately the same horizontal level as the upper surface of the front longitudinal frame member I5. The outer end of the wing 32 is curved upwardly and one .side of the lower wing 3l is bent inwardly to provide a bracket 34. A latch member 35 is pivotally secured to the bracket 34 so as to swing about a horizontal axis substantially parallel to the frame member I5, this latch being formed with a recess 36 and a cam-like nose 31, the upper edge of which is disposed below the wing 32 a distance less than the depth of the wing Ia of the frame member I5, as shown in Fig. 3. The wing I5a provides, in effect, a catch or abutment adapted to interlock with the recessed portion of the latch 35 when the sections are in nested position.

The lower end of the latch 35 extends below the lower edge of the front wall 4 and is formed with an enlarged end portion which constitutes a han dle 38 by means of which the latch may be released. A small tension spring 40 (Fig. 3), connected at one end to the latch and at its opposite end to the wing 32, normally holds the latch in catch engaging position and the handle 38 inwardly of the front wall 4, but permits the latch to be swung to a released position wherein the interlocking parts are clear of each other so that the outer section may be moved to extended position.

When the outer section of a couch constructed in accordance with the present invention is moved or pushed from an extended position to nested position, the wing 32 rst engages the upper surface of the longitudinal member I5 and thus holds the parts at al predetermined horizontal level so that when the nose 3l strikes the lower edge or Wing |523 these parts become nterlocked, as shown in Fig. 3. When the sections are in nested position with the latch 35 in engagement with the wing or catch I5a, the back and inner section may be tilted (as indicated by the dot and dash lines of Fig. 3) Without danger of releasing the latch, and hence when the couch is occupied there will be no liability of the latch becoming accidentally released, even though the occupants lean against the baci: rest and subject the section to forces which otherwise would separate them.

When it is desired to move the outer section to Aextended position, it is merely necessary to swing the handle 38 outwardly, using either the hand or toe, and the same movement which releases the latch is eifective to cause initial movement of the outer section toward its extended position. When the outer section has been drawn to fully extended position, the hook I8 operates to limit further outward movement in the manner previously explained, but Where it is desired to form twin beds. the hook I8 may be swung upwardly from the recesses I9 in the legs ID, thus permitting the sections to be completely separated.

While I have shown and described one desirable embodiment of my invention it is to be understood that this disclosure is intended for the purpose of illustration and that various changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described, may be made Without departing from the spirit and scope of the invention as set forth in the appended claim.

I claim:

In a couch bed having inner and outer sections capable of relative movement from a nested to an extended position and a back rest carried by one of the sections, releasable locking means for holding said sections in nested position, comprising a longitudinally extending frame member carried by one of said sections and dening an abutment, an inverted substantially L-shaped member carried by the other of said sections and arranged so that its upper wing extends horizontally and engages the upper edge of said abutment when said sections are in nested relation, a latch pivotally mounted on the lower wing of the inverted substantially L-shaped member and arranged so as to engage and lock the lower edge of said abutment when said sections are in nested relation, and resilient means urging said latch toward locking position.

JACOB C. FELDMAN.
