BEDFRAME SUPPORT LEG Filed Dec. 5, 1956 INVENTORS. MELVIN E. ROCHE y LESLIE K. JACKSON ATTORNEYS BEDFRAME SUPPORT LEG This invention, relating as indicated to a bedframe support leg, is a continuation-impart of our application Serial No. 462,264, now Patent No. 2,772,424, filed October 14, 1954, entitled Bedframe Support Leg.

This invention relates to bedframes, and more particularly to support legs and bedframe constructions adapted for partial disassembly for transport, which frames are normally made from metal rails of right angle shape in cross section.

A principal object of this invention is to provide an improved and simplified combined brace and supporting leg structure in the vicinity of the intersection of the longitudinal and transverse frame elements.

Another object is to provide an integral brace and leg structure adapted, in combination with a transverse frame element, for co-active interlocking perpendicular 'relationship with a longitudinal frame element at either end of the transverse element to eliminate the need for separate right and left units.

Still another object of the invention is to provide an improved brace and leg structure adapted, in combination with the transverse frame element, to support the frame at a point recessed inwardly from the longitudinal frame element.

A further object of our invention is to provide a bedframe having an inexpensive but sturdy pivotal connection between the longitudinal and transverse frame elements so that these elements may be shipped compactly partially unassembled in longitudinal alignment and still may be readily assembled in locked operative right angle relationship with minimum effort by inexperienced users.

Another object is to provide in an integrally formed brace and leg construction a vertically extending reinforcing rib or channel conformation.

To the accomplishment of the foregoing and related ends, said invention then comprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail a certain illustrative embodiment of the invention, these being indicative, however, of but one of the various ways in which the principles of the invention may be employed.

A principal problem in the structural design of bedframes sometimes referred to as the Hollywood type, i.e., box spring support frames normally used without a footboard and frequently used without a headboard, is the atet ' directed legs hereinabo-ve referred to.

provision of suflicient rigidity in the frame and strength in the leg structure to accept the severe end, oblique and twisting forces to which bedframes are subjected in use. Transportation costs necessitate that frames be as light as possible consistent with strength requirements and that they be capable of being shipped in knockdown condition with the ultimate user having to complete the assembly. has shown that it is highly desirable from a users safety and convenience standpoint to recess the support legs inwardly of the sides and ends of the frame to reduce foot stubbing and tripping accidents when the bed is being made. Location of the support legs inwardly of the frame periphery, together with the use of casters, requires exceptional strength in the frame supporting structure and heretofore it has been difficult to achieve this economically with light gauge angle iron members because of their inability to withstand deformation in the absence of cumbersome bracing arrangements.

To overcome the structural difficulties referred to above and the disadvantages of the prior art in bedframes of this type, we have invented a compact, simple and reliable, integral brace and support structure involving a novel cooperative interaction of longitudinal, transverse and leg elements.

Referring now more particularly to the drawings we have shown in Fig. 1 a bedframe of the Hollywood type in the process of being opened from its closed or shipping condition. The frame comprises a pair of longitudinally extending side rails 3t which have horizontally extending legs 31 and vertically extending legs 32. Shown pivotally attached to the longitudinal side rails are transversely extending cross rails 4%) which are in the process of being brought to an open condition as indicated by the arrows. These cross rails 4% have a horizontally extending upper leg 42 and a vertically depending leg 41. At the end of the frame are shown a pair of end plates 50 to which a headboard, not shown, may be attached. Adjacent the intersection of the transverse and longitudinal rails are shown our new integral brace and leg structure. It will be apparent from Fig. 1 that the cross rails are adapted in the closed condition of the frame to be brought into alignment with the longitudinal rails 30 so that the frame elements can be brought together compactly for shipment. In the fully assembled form (not shown) the rails are secured together, that is, the transverse or cross rails 4% are secured together as by suitable tension clasps or other means to provide for a unitary but transversely adjustable structure.

As indicated in this figure, preferably each of the rail elements 30 and 40 will have horizontally and vertically The vertically extending legs or runners 32 of the longitudinal elements 3% are adapted snugly to contain the edge of a box spring or the like and the horizontally extending legs or portions 31 normally will be the load carrying surfaces of the bed frame. The transverse or cross rails 40 will ordinarily be inverted, i.e., in comparison to the longitudinal rails,

and the horizontal leg 42 is uppermost so that it may act as a load carrying surface. In the form of the invention illustrated transverse rail 40' is pivotally attached to the longitudinal rail 30 by means of a rivet or similar element 48 as shown in Figs. 1 and 4 with the horizontally extending surface 42 of the cross rail 40 being operative beneath the horizontal leg 31 of the longitudinal rail 30 and it may be spaced therefrom as by a washer or the like (not shown).

To the outer surface of the depending leg 41 of the cross rail 40 is secured an integral brace and leg structure generally identified at 10. This leg element comprises a horizontally extending shoulder or flange 11 as more particularly brought out in Figs. 2 and 3, and a web- In addition to these requirements, experience 3 like vertically depending portion having lateral wings 12a and 12b on each side of areentrally disposed channel or rib formation 13. The reinforcing channel portion 13 extends into the horizontally extending flange 11 as at 20 to give additional rigidity to the structure. At the lower end of the channel in the portion generally indicated by the numeral 14 the wings 12a and 12b are brought more closely together as by means of a crimping die to provide a cavity for a caster spindle socket 15.

The brace and leg member is adapted to be secured to a depending leg of the transverse element of the frame through apertures 16a and 16b by means of rivets 47 or by other suitable means such as welding or the like. It is perhaps appropriate here to point out that the attachment of the support leg 10 to the depending leg 41 of the transverse member provides, as may be observed in Fig. 4, a sturdy T-like section. The formation of the T section adjacent the contacting end of the transverse member 40 with the longitudinal rail 30 provides a reactive force against torsional effects on the transverse member resulting from offset loading characteristics of tracking casters. It should also be emphasized that the amount of strength in the combination of the web or wing portions 12a and 12b of the leg to the dependent leg 41 of the transverse member is further increased by the brace of the channel formation intermediate the wings. The generally arcuate shape of the reinforcing channel 13 is apparent from the views shown in Figs. 24 and the depth of the channel will ordinarily be least at the upper end and greatest at the lower end.

In the form of the invention illustrated in the upper surface 11 of the brace and leg structure there is provided a lance-like element cut from the surface, leaving aper ture 1Z5 thercbelow. The lance element 17 is adapted to fit above the horizontally extending leg 31 of the longitudinal rail. When the transverse rail with the leg attached thereto is swung into operative position it will be apparent that the lance is adapted to hold the transverse rail perpendicular to the longitudinal rail. It may also be observed that the portion of the flange 11 forward of the lance, i.e., extending toward the longitudinal rail, will fit beneath and support the surface 31 of the horizontally extending leg 31 of the longitudinal rail 30. The lower surface of the lance will also fit upon and grasp the upper surface 31a of the longitudinal rail.

When the longitudinal and transverse elements are in assembled form and are perpendicular one to the other as is shown in the relationship apparent in Fig. 4, the coactive relationship of the members may be clearly understood. The transverse rail 40 will be pivoted by appropriate means as about a rivet 49 into a position perpendicular to the longitudinal rail 30. As the transverse rail is swung in this position the lance on the brace and leg element fits over the top of the longitudinal rail. Thus the transverse rail is in effect secured to or braced with respect to the longitudinal rail both at the pivot 48 and at the lance area. We found it desirable to space these contacting areas longitudinally along the rail surface 31 for greater rigidity.

In Fig. 4 in the fragmentary view given we have broken away part of the vertically extending leg 32 of the rail 30 to illustrate the pivotal relationship of the transverse element. We have also shown the relationship of the horizontal leg surface 31 positioned under the lance element 17 and over that portion of the horizontally extending shoulder or flange 11 as shown in broken lines.

In Fig. 4 we have also illustrated the relationship of a caster arrangement with the brace and leg element. A caster fork as at 56 has at its lower portion a pin 57 adapted to carry a caster wheel 58. It will be understood that a glide or other lower floor contact means may be substituted for the caster arrangement shown.

We wish it to be-understood that while we have shown the use of a lance struck from the surface 11 of the brace and leg element as an abutment and support means for maintaining the perpendicular relationship illustrated in Fig. 4, other abutment or support means may be substituted without departing from the nature of the invention. For example, rivets projecting downwardly from the surface 31b of the rail 30 could be adapted to fit into a prepared recess cut into an end of the horizontal flange 11. Similarly a lance could be struck from the surface 31b adapted to receive and hold a portion of the leg flange 11. The flange and longitudinal rail may also be detachably secured together as by a nut and bolt or by other suitable means known in the art.

Under certain conditions we may also reverse the operative relationship illustrated in Fig. 4. Thus the flange 11 may be pivotally connected to the leg 31 with the transverse element containing in the leg 42 appropriate means for coactive abutting and/or support relationship with leg 31. It will also be appreciated that with appropriate modifications the flange 11 may carry a lance at the opposite end or at both ends for reversible position in the frame.

In view of the foregoing, it is submitted that the obiects of the invention have been achieved and that a novel frame assembly and support means have been provided having a sturdy reinforced construction lending rigidity to the frame and having an attractive, simple structure and appearance.

Since the invention may be embodied in other specific forms, without departing from the spirit or essential characteristics thereof, the present embodiments are to be considered as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
