ADJUSTABLE WIDTH KING SIZE BED FRAMES The present invention relates to an adjustable width bed frame and more particularly to an improved adjustable frame construction which includes a center support assembly that is assembled without the use of loose fasteners such as nuts and bolts. Novel center cross rail sections and positioning means therefor are also provided.
BACKGROUND OF THE INVENTION Bed frames which have adjustable length cross rails so that the frame may be adjusted to form different size beds have heretofore relied either on clamps or on nuts and bolts to hold the cross rails together and to main tain the proper spacing between the side rails of the frame. The use of either nuts or bolts or clamps necessitates the use of tools in assemblying the bed frame and, since these components are loose, that is they are not an intregal part of the frame, there is a danger that the components may become separated from the frame during shipment or when the frame is stored. A further disadvantage of the systems which employ clamps is that the width of the frame can be determined only by measurement. Also, if the clamp should become loosened the side rails of the frame may move apart.
In my earlier filed pending application, Ser. No.-
173,107 filed Aug. 19, 1971, for Lock Type Adjustable Width Bed Frame there is disclosed a bed frame in which the cross rails are formed at two sections which are provided with interlocking shouldered rivets and notches so that the frame may be assembled to a desired width without the use of any tools. The notch arrangement assures that the frame is at the proper width without the necessity of measurement. The present invention is directed to an improvement of the frame shown in my earlier application. Particularly, the pres ent invention is directed to a bed frame of larger size than that disclosed in the above-mentioned application. Also, the present invention provides a center support subassembly for the bed frame.
It is the primary object of the present invention to provide an adjustable width bed frame which may be assembled without the use of tools and which has no loose or separate components.
It is also an object of the present invention to provide an adjustable bed frame which includes a center support subassembly with the subassembly being secured to the frame without the use of tools or separate components.
It is a further object of the present invention to provide a bed frame of the Hollywood type which is easily adjustable in width.
The above and other objects of the invention which will become apparent in the following detailed description are achieved by providing an adjustable bed frame which consists, essentially, of a pair of side rails, a pair of cross rail subassemblies, and a center support subassembly. Each of the cross rail subassemblies is comprised of a pairof cross rail sections which are connected to the respective side rails and to a center cross rail section. The center cross rail section is provided with upwardly projecting shouldered rivets and L- shaped notches are provided in the cross rail sections for engaging or receiving the rivets to retain the rail sections as a unit. The center support subassembly consists of a rail which is connected to each of the center sections of the cross rail subassembly, shoulder rivets being provided at each end of the: center rail and arcuate slots being provided in the center cross rail section for receiving these rivets.
For a more complete understanding of the invention and the objects and advantages thereof reference should be had to the following detailed description and the accompanying drawing wherein there is shown a preferred embodiment of the invention.
In the drawing:
FIG.'1 is a perspective view of the bed frame of the present invention;
FIG. 2 is a fragmentary top plan view showing one of the cross rail subassemblies of the frame of FIG. 1;
FIG. 3 is a fragmentary top plan view showing the center support assembly being connected to the cross rail assembly;
FIG. 4 is a fragmentary top plan view showing the center support rail and cross rail assembly in assembled relation;
FIG. 5 is a transverse sectional view taken along the line 5-5 of FIG. 1; and
FIG. 6 is a fragmentary transverse sectional view taken along the line 6-6 of FIG. 4.
The bed frame illustrated in FIG. 1 is designated generally by the reference numeral 10 and is a Hollywood type frame having a pair of side rails 12 and 14, a center support subassembly 16, and a pair of cross rail subassemblies 18. Each of the side rail assemblies 12 and 14 consists of a side rail 20which may be provided with a headboard plate 22 at one end thereof and is provided with a pair of legs 24 near opposite ends of the rail 20. The legs 24 extend downwardly and are formed at their lower ends into sockets 26 for receiving the stems of casters 28. It should be noted that the upper portions of the legs 24 comprise longitudinal flanges.
Each of the cross rails assemblies 18 is formed of a pair of end cross rail sections 30 which are pivotally connected to the respective side rails 20 by rivets 32 or other suitable fasteners and a center cross rail section 34 which joins the two end sections 30. The manner in which the end cross rail sections 30 are joined to the center section 34 can best be seen in FIGS. 2 and 5. As can be seen from FIG. 2, each end cross rail section is provided with a number of L-shaped slots or notches 36-3611 and the center cross rail section is provided at each end with pairs of upwardly projecting rivets 38 and 38a. Each of the notches 36 has an entry portion 40 extending inwardly from the edge of the rail section 30 and an inner notch 42 extending at right angles to the entry portion 40 and toward the center line of the bed frame. It will be noted that the notches are arranged in a pair-like fashion with the notches of each pair being spaced from one another by the same spacing as are the rivets 38 and 38a. Thus, the notches 36 and 36a form one pair, the notches 36b and 36c form a second pair, while the notches 36c and 36d form a third pair. Preferably, the pairs of notches are spaced apart from one another so that standard widths of bed frames can be made by selecting appropriate pairs of notches. For example, the first pair of notches may be spaced apart so that a queen" size bed frame is formed when these notches are used. Similarly, the second and third pair of notches may be spaced apart by the distances necessary to make California king and standard king size bed frames.
As will be seen from FIG. 5, each of the rivets 38 has a shoulder portion 41 and a head 44. The diameter of the shoulder portion of the rivet is slightly less than the width of the slot 38 and the depth of the shoulder 41 is at most slightly greater than the thickness of the flange 30a of the rail section 30. It should be noted that as a result of the fact that the inner portions 42 of the notches are all directed toward the center line of the bed it is necessary to move the side rail assemblies 12 and 14 toward one another to release the rivets 38 from the notches. When a mattress and box spring assembly 56 is positioned on the frame, movement of the side rails 12 and 14 toward one another is prevented so that the frame assembly is effectively locked together.
- The center support assembly 16 may consist of a pair of angles 46 which are joined in back-to-back relation to form a T-shaped member. Legs 56 are provided near the opposite ends of the center support member 16 and these legs are provided with casters 58 which provide additional support for the bed frame. In order to connect the cross rail assemblies 18 and the center support assembly 16, a pair of arcuate slots 48 are provided at the center of the center section 34 of the cross rail assembly. Each of these slots has its center of curvature at the inner end of the opposite slot. A pair of shouldered rivets 50 are provided at each end of the center support rail assembly for engagement with the slots 48 and these rivets 50 are spaced apart by a spacing equal to that of the inner ends of the two slots 48. As is shown in FIG. 6, each rivet has a shoulder 52 and a head 54 with the shoulder being of a diameter slightly less than the width of the slot 48 and of a depth slightly greater than the thickness of the flange portion 34a of the center section 34 of the cross rail assembly. The center support assembly 16 is connected to the cross rail assembly 18 by first positioning one of the rivets 50 in the corresponding slot 48, this being accomplished by movement generally in the direction of the arrow A. The center section 34 is then rotated as indicated by the arrow B to bring the second rivet 50 into. its slot 48. It will be readily apparent when the bed frame is fully assembled the center rail section 16 is firmly retained in place since the two slots 48 converge towards their open ends.
It will be understood that the side rails 20, cross rail sections 30 and 34, and the rail members 46 of the center support assembly may all be formed of angle stock in the conventional manner. Also, other supports may be used in place of the casters 28, if desired.
While only the best known embodiment of the invention has been illustrated and described in detail herein it will be understood that the invention is not limited thereto or thereby. Reference should therefore be had to the appended claims in determiningthe true scope of the invention.
