17 Claims. (Cl. '-310) This invention relates to beds and sofas and in particular is directed to the provision of improvements in supporting means for a bedspring whereby the same may be readily adapted for use as a bed or a sofa.

I have conceived of a means whereby a bedspring of suitable sturdiness may be readily, easily and cheaply provided with a set of improved supports of relatively simple construction, said supports being easily aflixed or removed, so that a structure can be made available with minimum expense which affords either seating or sleeping accommodations.

Accordingly, it is among the objects of this invention to rovide improved supports for bedsprings characterized by relative simplicity of construction, the supports being readily atfixable to the frames of a bedspring so as to convert the bedspring into a structure that may be used both as a seat and as a bed.

Further objects and advantages will become apparent from the following more detailed description of my invention taken in connection with the accompanying drawings wherein:

Fig. 11 is a cross sectional view showing another form of the invention shown in Fig. 10.

In its fundamental aspects, the primary object of my Patented Get. 30, 1956 invention is achieved by a demountable support for a bedspring which comprises a channel-like member having a bottom and side adapted to receive the rail of a bedspring frame, said channel member having means extending therefrom adapted for engagement by a clamping member, a leg depending from said channel to maintain said rail in elevated position, a clamping member mounted over said rail, the clamping member having means adapted to engage the correlated means on the channel and tightening means whereby the rail and leg are clamped in rigid assembled relationship.

Referring now to the drawings, and particularly with reference to Fig. 1, the numeral 20 designates a tubular rail such as commonly used for the type of flat-spring bedspring frames. The rail 20 is received in channel member 22 comprising bottom 24 and walls 26. The leg 28, affixed to the bottom of the channel, maintains the bedspring in elevated position when the device is assembled. Member 22 is provided with oppositely disposed flanges 30 which extend outwardly from side walls 26.

Clamping member 32 consists of a substantially C- shaped piece having generally fiat side 34 fairing into lateral ends 36, the latter being provided with inwardly disposed flanges 38. As can be seen from the drawings, when clamping member 32 is mounted over rail 2%, flanges 38 engage flanges 30 of the channel piece 22. By tightening set screws 49, which extend through threaded bores in wall 36, the rail 20, channel member 22, leg 28, and member 32 are clamped into rigid assembled relationship.

U-shaped member 50 may be advantageously used in conjunction with my device as a centering means for bedspring rails of tubular or circular shape. With such rails it is of importance that set screws 40 clamp down upon the midpoint of the tubular rail. If the set screws strike the rail off-center, there is a likelihood that the rail will slip away from the screws when under pressure thereby causing leg 28 to incline and buckle. When U-shaped member 50 is used in conjunction with my device to center tubular rails, the said member is nested within channel piece 22, as shown in Fig. 2, to receive tubular rail it prior to clamping. In this instance, ribs 52, projecting from U-shaped member 50, provided the member with a gripping surface and help take up clearances which may exist between the rail and the channel piece 22.

By forming the bottom 24 of channel piece 22 with a recess 56 therein, I provide a means whereby the leg 28 may be aflixed to bottom 24 by means of nuts 53 and 69, the latter being received in the recess so as not to interfere with the resting of the rail on the bottom for rigid clamping. As can be seen from the drawings, especially Fig. 1, the rail, when positioned for clamping, overrides nut 64) and the threaded end of leg 28, which are retained in recess 56 and do not project above the top surface 2 of the channel.

In Fig. 3, the structure is shown in assembled relationship with an angular rail. In this case, the U-shaped piece 50 is set in channel piece 22 to provide a rest for the horizontal web 44 of the angular rail. In Fig. 4, a wooden block 46 is shown as the rest or support for web 44 instead of piece 50. In lieu of piece 50 or block 4-6, the channel piece 22 may be provided, as shown in Fig. 6 with one or more vertical disposed and adjustably positionable set screws or bolts 48 to provide support for horizontal web 44.

If the horizontal web 44 of an. angular rail 42 is, as seen in 'Fig. 7, wide enough to rest on one of the flanges 30 of 22 when the vertical web lies along the opposite vertical wall of 22, a separate support for the horizontal web 44 may be dispensed with.

As shown in Fig. 5, the side of the rail, instead of the top thereof, may be the part to which the structure of this invention is clamped. In this modification leg 28 depends from a side 26' of channel piece 22' instead of from the bottom of the channel piece as in the prior forms. The side 26' may have a recess 56 akin to 56.

The structure shown in Pig. 8 is akin to that of Fi 2 except for the cross section of the rail 20' which, in this case is oval.

As shown in Fig. 9, the embodiment of the invention comprises a channel piece 23, having a bottom 25 and walls 27. The bottom is provided with a recess 57. Walls 27 terminate in outwardly extending flanges 31. A tubular rail 20, is centered and pinned by projections 59 punched up from bottom 25 when clamping member 32 is placed in operative position akin to that position in Figs. 1 and 2.

As shown in Fig. 10, channel piece 70 has a bottom 72 which is recessed as at 74. A wooden leg 76 may be secured to the underside of the recess 74 by means of hanger bolt 78. v Hanger bolt 78 is secured to the leg 76 by the wood screw section 80 thereof. The externally disposed portion of hanger bolt 78 is provided with machine screw threads as at 82 so that the leg can be secured to the channel piece by engagement with the threads of orifice 84, and, if desired, further by locknut 86. Orifice 84 may, if desired, be left unthreaded, in which case, nut 86 cfifectuates the holding of the leg to the channel.

As shown in Fig. 11 channel piece 90 has a bottom 92 which is recessed as at 94, the recess having a centrally disposed downwardly extending tubular extension 96. Wooden leg 98 is secured to piece 90 by means of hanger bolt 100. The hanger bolt is secured to the wooden leg by means of the wood screw section 102 thereof. The upper face of leg 98 is recessed to receive 96. The latter may be threaded internally as shown, to receive the machine screw threaded portion 106 of hanger bolt 100. Nut 108 may be used to lock the hanger bolt in position.

It will be understood that the terms horizontal and vertical as used herein have reference to directions with respect to the normal position of a bedspring when in use.

It will be apparent from the foregoing description of this invention that the device basically comprises a channel piece which serves to receive the rail of a bedspring frame, the channel piece having longitudinally extending flanges; a leg either permanently (by welding or peening or other suitable means) affixed, or demountably aflixable to the channel piece, also optionally means for centering and/ or positioning the rail when received in the channel, a C-shaped member that completes coverage or engirdling of the rail and has means for engaging the flanges of the channel piece, and means to tighten the rail when received in the channel, the cover member and channel into clamped rigid assembled relationship.

It will be further evident that the channel piece can readily accommodate legs of any length and any shape or dimension of wood or steel with a threaded bolt inserted, thereby allowing for a wide variety of heights, as well as a wide variety of uses.

It will be understood that the foregoing description of the invention and the embodiments illustrated are merely illustrative of the principles thereof. Accordingly, the appended claims are to be construed as defining the invention within the full spirit and scope thereof.
