14 Claims, 8 Drawing Figures tion relates to a Hollywood-type bed I 1 BED FRAME wmr DETACHABLE SIDE RAILS BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a bed frame with detachably connected end and side rails.'ln particular, this invenframe having a rectangular shape.
2. Description of the Prior Art Hollywood-type bed frames having a rectangular shape and detachable side rails are known. These known bed frames have various constructions for attaching the side rails to the end rails and/or to a headboard. While it is generally desirable to have a bed frame with detachable siderails for convenience in assembling and disassembling, it is also necessary that the connection be sufficiently rigid to prevent rocking during use and when the bed is moved from one position to another by exerting a force at, for example, an end thereof. The supporting engagement of the casters or other floor engaging devices with a floor tends to rock the legs on the frame when the bed frame is so moved.
SUMMARY OF THE INVENTION It is an-object of the present invention to provide a bed frame with detachable side rails which has a construction permitting easy assembly and disassembly of the frame while providing a rigid connection between the various rails.
This and other objects are accomplished according to one embodiment of the present invention by providing a bed frame with detachable side rails and having a rectangular shape which includes a pair of longitudinal side rails having spaced end portions and a first transversely extending member provided with at least one keyhole slot and arranged at the end portions, and a pair of longitudinal end rails having spaced end portionsand second transversely extending members providedwith at least one pin and arranged at the rail end portions for mating with slots and connecting the side rails to the end rails.
In this embodiment according to the present invention, the first transversely extending members each is partially formed as a longitudinally extending plate provided with perpendicularly extending and codirectional flanges on the longitudinal edges forming a channel in which the second transversely extending member is received for restricted movement therein. The second transversely extending members each is formed from an L-shaped bracket, with one leg provided with the pin and dimensioned to mate with the channel for preventing a rocking movement between the two members. The two members are arranged for normally lying in a vertical plane.
The side rails may be L-shaped angles, each having the first members connected to the inner surface of a leg thereof and arranged parallel to and spaced from the other leg. The end rails may be T-shapedmembers provided with a stem, and having a leg of the second member connected to the stemand arranged parallel thereto, while the other leg of the L-shaped bracket is arranged perpendicular with respect to the other leg and the stem. The first member has. a pair of longitudinally spaced keyhole slots, and the second member has a pair of mating headed pins.
Another and preferred embodiment of the invention includes a bed frame with side rails detachably and rigidly connected to end rails in which the side rails have a depending bracket at each end thereof and each end of the end rail is provided with a bracket cooperatively associated with the bracket on the side rail for detachable and rigid connection therewith. The detachable connection includes a pair of headed pins on the bracket on the side rail and a pair of keyhole slots on the bracket on the end rail with the pins and slots being vertically oriented and vertically engaged with the two brackets including vertically disposed and engaged flange surfaces to rigidify the connection.
Another feature of the preferred embodiment of the invention is the provision of a detachable clip on the side rails for engaging the lower corners of the bed springs to facilitate the mounting of the clips on the side rails and facilitate shipment of the bed frame in a compact condition inasmuch as the chips may be detached from the side rails during shipment thus reducing the overall size of the bed frame when collapsed and reducing damage to cartons for the bed frames when they are shipped with rigidly mounted clips.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. l and 2 of the drawings show a bed frame 10 having a rectangular shape and a pair of longitudinal side rails 12 with spaced end portions 14. Rails 12 have first transversely extending members 16 which are provided with at least one keyhole slot 18 and arranged at the end portions 14. Frame 10 also has a pair of longitudinal end rails 20 having spaced end portions 21. Rails 20 have second transversely extending members 22 provided with at least one pin 24 arranged at end portions 21 for mating with a slot 18 and rigidly conneeting side rails 12 to end rails 20. Pin 24 is of a conventional design with a head 26 and shank 28. Members 16, 22 are arranged for normally lying in a vertical plane.
FIGS. -7 illustrate a preferred embodiment of the connection between the side rails and end rails and FlG.-8 illustrates a detachable clip mounted on the side rail for retaining the box springs in position on the frame.
In theconstruction illustrated in FIGS. 5-7, the detachable connection interconnects a side rail 70 and an end rail 72both of which are of angle iron construction with the horizontal flange disposed uppermost. A bracket 74 is attached to the side rail 70 and a bracket 76 is attached to the end rail 72 and the brackets 74 and 76 are vertically interlocked with each other. The bracket 74 includes a vertical plate 78 having a pair of outwardly extending attaching lugs 80 at the upper end thereof secured to the vertical flange of the side rail 70 by rivets 82 or by any other suitable construction. As illustrated, the plate 78 is slightly offset in relation to the lugs 80 as at 84. This offset 84 provides a space between the plate 78 and the vertical flange of the side rail 70 as illustrated in FIGS. 6 and 7 and also serves to rigidify the bracket 74.
The lower side edge portion of the plate 78 is provided with a pair of parallel flanges 86 which together with the plate 78 form an inwardly opening vertical channel-shaped stabilizing structure for receiving the bracket 76. Mounted on the plate 78 is a pair of vertically aligned and spaced headed pins 88 which are riveted to the plate 78 in a well known manner.
The bracket 76 includes a vertical plate 90 having a pair of keyhole slots 92 formed therein with the downwardly extending notch 94 defining part of the keyhole slot having side edges which converge slightly towards each other so that when the headed pins 88 are inserted through the keyhole slots and move downwardly, the side edges of the notches 94 will tightly and frictionally grip the shank portion of the headed pin 88 thus rigidly connecting the bracket 76 to the bracket 74. The
FIG. 8 illustrates a right-angular clip 104 having a horizontal flange 106 resting on the top surface of the top flange of the side rail 70 and a vertical flange 108 extending upwardly from the outer edge thereof for engagement with the box springs normally positioned on the bed frame. The inner edge of the flange 106 is provided with a downwardly offset tongue 110. The tongue 110 is generally parallel to the flange 106 and downwardly offset therefrom by an offset portion 112 with the offset portion 112 and the tongue 110 being narrower than the flange 106. The tongue 110 and a portion of the offset portion 112 is inserted downwardly through a slot 114 formed in the top flange of the side rail 70 so that the clip 104 may be assembled by inserting the tongue vertically down through the slot when the flange 106 is substantially vertical after which the clip is rotated downwardly until the flange 106 rests against the top flange of the rail 70 with the vertical flange 108 extending upwardly from a position in alignment with or just outside of the vertical flange of the rail 70 thereby providing clips for engaging the box springs and retaining them in secured position on the frame. This construction also enables the frame to be shipped in a knockdown position with the two end rails and the two side rails detached from each other and compactly nested in relation to each other with the clips 104 and the casters or other floor-engaging elements being provided in a separate container such as a bag or the like which may be inserted into a void area in the package thereby providing not only a compact nested arrangement of the knocked-down frame but also one which can be inserted into a cardboard carton with no sharp projections such as would occur if the clips were permanently attached to the side rails in a manner so that they projected above the horizontal top flange of the side rails.
In both arrangements, the taper of the notches defining the keyhole slots and the orientation of the pins and notches are such that the weight supported by the side rails will facilitate and retain the rigid interconnection. Also, the inwardly opening channel on the bracket on the side rail in each arrangement engages and receives the side edges of the corresponding vertical plate on the bracket on the end'rail thus further providing a rigid connection and preventing fore-and-aft rocking movement of the legs and end rails supported thereby when the bed frame is being pushed or pulled endwise. The two spaced headed pins and keyhole slots together with the plate-to-plate engagement between the bracket plate on the side rail and the bracket plate on ofthe invention.
the end rail and the fact that the thickness of the plate having the keyhole slots therein is substantially the same as the distance between the headed end of the pin and the adjacent plate on which the pins are mounted will'prevent' anylateral rocking movement of the side rails in relation to the end rails thereby providing a rigid connection'in all directions but yet a connection which may be readily released by exerting relative vertical forces on the end and side rails to disengage the vertically interlocked keyhole slot and headed pin connection.
The foregoing is considered as illustrative only of the principles of the invention.
