2 Claims.

Our invention is an improvement in convertible couches of that particular type comprising two sections mounted one upon the other when arranged to form a couch, and in which the uppergnost section is slidable upon the floor for the extension thereof in forming a bed, now. commonly known as studio couches.

In the construction of the conventional type of studio couch the smaller or under section, nested beneath the larger or uppermost section, remains stationary and therefore rests firmly upon the floor while the uppermost section, which provides for the extension of the couch in forming the bed, is provided with rollers or casters for convenience in sliding the same to the different positions. This simple construction has met with the objection that when arranged as a couch the uppermost section, being easily rolled upon the floor, was apt to move forward when a person was seated thereon, and to overcome the free movement of this section means have been provided for either locking both sections together in closed position or for allowing spring depressed front rollers or casters to recede into the lower ends of the legs by the weight of a person seated on the couch, thus more firmly holding said uppermost section in place. However, the devices generally provided for this purpose either add to the expense of manufacture or are not entirely satisfactory in accomplishing what is desired in operation.

The main object of our invention therefore is to provide a simple and inexpensive locking means in the form of a rigid catch plate attached to the framework of one of the sections, preferably the slidable uppermost section, and adapted to cooperate with the framework of the other or stationary section in not only locking both sections together when closed one upon the other but to slightly lift the front end of the uppermost section from contact with the floor, and at the same time effect engagement of the catch in a morepositive manner when a person is seated on the couch, the form of catch plate depending upon the peculiar construction of the couch section to which it is applied, as hereinafter fully set forth.

In the drawings:

Figure 1 is a perspective view of the framework of a studio couch to show the application of the catch plates thereto, the sections being extended.

Fig. 2 is a transverse sectional View with the couch sections closed one upon the other.

Fig. 3 is a perspective view of the preferred form of catch plate in accordance with vention.

Figs. 7, 8, and 9 are views similar to Figs. 4, 5, 10 and 6, illustrating a further modification, and 7 Figs. 10 and 11 are side and bottom plan views of another modification of the combined lifting device and catch.

our in- The framework of the two sections of a studio l5 couch is usually constructed of steel, an example being shown in Fig. 1 of the drawings in which both sections In and II are made up of longitudinal and transverse angle bars l2, l3 riveted together at the corners and supported on legs [4, IS in the form of angle plates, the lower end of the corner posts or legs l5 of the smaller or stationary section II resting directly on the floor while the corner posts or legs Id of the slidable uppermost section In are provided with rollers l6 for easily rolling this section on the floor in converting the piece of furniture from couch to bed and vice versa. These couch frames are usually provided with suitable spring bottoms, but the general construction of the same forms no part of our present invention, it being necessary only that in some instances the longitudinal bars at the front of the frames l0 and ll be angle bars to cooperate with the rigid catch plates hereinafter particularly described, and for convenience in describing the application and operation of said catch plates the angle bars at the front ends of said couch frames are referred to by the numerals l2a and 12b respectively.

In that form of the combination lifting device and catch illustrated in Figs. 1 to 3 it is shaped to provide a body portion or plate I! with a laterally projecting flange 58 at its upper longitudinal edge by which it is attached to the angle bar l2a of the uppermost section of the couch, by means of rivet l9, and the lower edge of the body portion is shaped for effective engagement with the angle bar 12b of the lowermost or stationary section. For this purpose the lower edge of the body portion or plate is provided intermediate its ends with a recess of a length to correspond with the width of the upper member of angle bar IZb and of sufiicient depth to provide an abutment 2| at its inner end while at the other or outer end the plate is narrowed and 55 shaped to form a projection 22 with oppositely inclined edges 23, 24, the forwardly inclined edge 24 being at the end of the plate and comparatively long to serve as the lifting element of the catch. As will be seen the catch plate is in the general form of a hook but of peculiar shape to meet certain requirements; that is to say, it is especially adapted to be rigidly and securely fastened to the inner sides of the angle bar 2a With the flange I8 in intimate engagement with the uppermost member of said angle bar and the inner edge likewise in intimate engagement with the vertical member, and as the catch projects inwardly from the angle bar on the slidable couch section it will ride over the angle bar |2b of the stationary couch section for locking en-.

gagement therewith, at which time the catch is resting on said angle bar |2b with the upper member of the latter confined within the recess 20 to prevent forward or backward movement of thecouch section. to which the catch, is attached. Catches constructed in accordance with our invention are secured to the front angle bar of the uppermost or slidable couch section l6 near the opposite ends thereof, andthefunction of these catches is not to merely lock the sections together but what is more important they operate to slightly lift the forward end of the uppermost section with the rollers ltjat this end off the floor so, that said couch section cannot be moved forward by a person sitting on the same, for the reason that the weight of the occupant augments the normal engagement of the, catch with angle bar |2b. In extending the uppermost of the couch sections it is necessary only to pull it outwardly when the inner inclined edge 23. of the projection or bill 22 ofthe hook-like catch and lifting device will ride over the inner edge of the angle bar |2b of the stationary couch section, and after the projection clears said angle bar the forward end of the slidable couch section will drop to rest on the rollers, and being then sup,- ported on all four rollers it may be easily rolled into bed position, In closing the couch this slidable section is pushed inwardly over the companion section, and the catch plates will auto,- matically ride over the angle bar |2b to lift the front end of the uppermost section and effect a locking engagement with said angle bar in slightly lifted position, in this operation the inner edge or abutment wall 2| striking against the vertical member of the angle bar to limit the in ward movement of the uppermost section. As will be noted the intimate engagement of the 3 inner and upper edges of the catch plate with the vertical and horizontal members of the angle bar to which it issecured will provide contact bearings to strengthen the attachment of the catch, thus requiring only a single rivet to secure it inplace.

The advantages of providing a rigid catch plate and lifting device of the construction and operating in the manner hereinbefore described will be appreciated by the manufacturers and users of studio couches, and it is obvious that the construction or shape of the catch may be modified without materially changing the operation or affecting its advantages. Consequently in Figs. 4 to 9 inclusive we have illustrated two modified forms, in each instance the combined catch and lifting device being rigidly secured to the angle bar-I'Za of the uppermost or slidable couch section and engaging the depending member of the angle bar IZb of the lowermost or stationary-couch section, in this instance the last mentioned angle bar being provided with a vertical slot l2c.

As illustrated in Figs. 4, 5, and 6 the catch and lifting device is shaped to present a hook-like projection 25 with an attaching member 26 at right angles thereto, said attaching member being secured to the vertical member of the angle bar |2a by rivet 21 so that the hook will project horizontally at such level that when the uppermost couch section is closed over the lowermost 10 couch section said hook will enter the slot |2c and support the forward end of couch section Ill with the front rollers slightly off the floor, as hereinbefore described with reference to the preferred form of catch. :80 that the forward end of the uppermost couch section will be slightly lifted when the sections are closed the outer end of the hook 25 of this modified form of catch is likewise beveled forwardly, as at 28corresponding with the inclined edge 24 at the outer end of catch plate |.'|.and to prevent movement of the slidable couch section when the catch is in engagement with the slot in the angle bar |2b said hook is, provided at its lower edge with an arm-- ate recess 2.9.into which the wall at the-lower end of said slot is received. This catch plateis also provided near the inner end of the upper edge of thehook-like portion with an abutment 30 for limiting the inner movement of the slidable couch, section with respect to the stationary 3O couch section, said abutment being incidental to the, reinforcement of the catch at the angle thereof. These catches are also rigidly secured to the angle bar l2a, one near each end thereof, and serve. to support the slidable couch section with the front supporting rollers off the floor, the engagement of the catches being augmented by the weight, of a person sitting on the couch.

Asillustrated in Figs. '7, 8, and 9 the form of combined lifting device and catch is also similar inpconstruction to the preferred form, in this instance adapting the device for attachment to the upper horizontal member of angle bar 2a instead of, thevertical member, for which purpose the billv 3| of the hook is at the lower endof a vertical shankllfrom which itv projects at right angles or horizontally outward, and the attaching member 33 projects at right angles inwardly from the upper end of said shank for attachment to the under side of angle bar |2a by rivet .34. In 5); this form of catch plate the movement of the slidable couch section over the stationary couch section is limited by that part of angle bar |2b aboveslot |2c striking against the shank of the catch, and as in the forms of constructionherein- 55, before described the bill of the hook has a forwardly inclined edge 35 at its outer end for raising the slidable couch section, and an arcuate recess 36 engaged by the lower end wall of slot I20.

As a further illustration of how our improved 0, combined lifting device and catch plate for studio couches. may be modified within the spirit and scope of the invention we have illustrated in Figs. 10 and 11 that form adapted for use in connection with a particular type of studio couch 5: in which the frame of the slidable section is. a little more elaborate to provide round corners, and consequently in this instance there is a wooden facing board or strip 31 attached to the longitudinal and transverse angle bars 38, 39, and a skirt 40 of metal fastened to the lower end of the wooden strip to the inner side of whichthe supporting rollers or casters 4| are attached. This frame construction forms no essential part of this application and consequently is merely to show the application of the proposed catch plate 50 in which one end 42 is bent at the proper angle for attachment to the metal skirt and the outer end provided with a forwardly inclined edge 43 in advance of an arcuate slot 44, the inclined edge serving to lift the front end of the slidable couch section and the arcuate slot of each catch plate engaging a lug 45 projecting outwardly from the front legs of the stationary couch section. In this example of supporting hook or catch plate the outer terminal, immediately beyond the inclined lifting edge, is bent outwardly to form a guide member.

Other modifications may be suggested inthe manufacture of the combined lifting device and catch for that type of couch in which one section is slidable over the other section, and we therefore desire that our patent protection as set forth in the claims be understood to cover obvious modifications which retain the general features of construction and advantages in operation.
