BACKGROUND OF INVENTION
In Hollywood style metal bed frames, it always is a problem to make these bed frames resistant to bending, and to provide sturdy, effective support legs therefor. These bed frames are made by a number of manufacturers and the pricing of the frames is quite competitive. Primarily, the bed frames are made from metal components, such as angle iron and stampings.
Inasmuch as portions of the bed frames, and especially the legs thereof, normally are quite noticeable in a room, it is quite desirable that the support legs be attractive in design and naturally be free from sharp edges or jagged corners which might injure or damage bed covers coming into contact therewith.
A number of patents have been issued heretofore on various designs of bed frame legs and representative patents in this field include U.S. Pat. Nos. D-179,428; 2,772,424; and 3,114,917.
The general object of the present invention is to provide a strong molded plastic leg for use in bed frames, and which leg is characterized by the provision of a main support column therein, and a pair of horizontal upper support flanges.
Another object of the invention is to provide a bed frame support leg of attractive design, which leg has no sharp corners or jagged edges therein, and which bed frame leg can be readily secured to other frame components to provide an operative structure.
A further object of the invention is to provide a one-piece support leg for a bed frame and wherein the bed frame support leg has a recess extending down thereinto from the upper edge thereof to permit a leg of a cross rail angle to be attached to the support leg from both sides of the angle leg.
Yet another object of the invention is to provide a bed frame support leg with a pair of upper load carrying flanges to engage the side rail and cross rail of a bed frame for adding strength and stability to the frame when in operative assembled position; to control pivotal movement of a cross rail in the frame by a lug on the support leg; and to provide a support leg which completely encompasses the caster stem socket for improved stability in the engagement of the caster stem with its positioning socket.
The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.
Reference now is made to the accompanying drawings, wherein:
FIG. 1 is a fragmentary perspective view showing the bed frame leg and its assembly into a portion of a bed frame;
FIG. 2 is a top plan of the bed frame leg with the bed frame components being shown in phantom;
FIG. 3 is a vertical section taken on line 3--3 of FIG. 2 with the bed frame leg and associated frame components being shown in assembled relationship;
FIG. 4 is a vertical section through a bed frame side rail showing an assembly of the bed frame leg and cross rail connected thereto;
FIG. 5 is a vertical section of the bed frame leg taken on line 5--5 of FIG. 4; and
FIG. 6 is a slightly enlarged horizontal section of the leg taken on line 6--6 of FIG. 4.
When referring to corresponding members shown in the drawings and referred to in the specification, corresponding numerals are used to facilitate comparison therebetween.
Attention now is directed to the details of the structure shown in the accompanying drawings, and a bed frame support leg is indicated as a whole by the numeral 10. This leg 10 is a molded, unitary product which is made from any suitable plastic molding material as is available commercially today. This support leg 10 is primarily designed for use with Hollywood bed frames and a side rail 12 of such a frame is shown in FIG. 1 of the drawings, while a cross rail section or cross rail 14 is also shown in the drawings and the leg 10 is used in operatively assemblying cross rails to the side rails in bed frames of the Hollywood style, as well as to provide mobile support therefor. These Hollywood bed frames are conventional in construction and are of the type as shown, for example, in U.S. Pat. No. 2,772,424. The cross rail 14 is pivotally secured to the side rail 12 as explained hereinafter in more detail. Normally, both the side rail 12 and cross rail 14 are made from conventional metal angles, and with the side rail 12 having a horizontal leg 16 and a vertically extending leg 18. The cross rail 14 normally has a horizontal leg 20 and a vertical leg 22 and the bed frame engages box springs or other bedding members in an operative bed frame.
The support leg 10 has a pair of parallel laterally spaced horizontally directed support flange members 24 and 26 provided thereon with the flange 26 being slightly lower than the flange 24, and with the flange 24 primarily comprising spaced sections or wings 24a and 24b separated by an open upper end 28 of a center vertically extending tubular support section or column 30 formed in the leg. An upwardly protruding locking lug 32 is formed on the upper end 28 of the center support column 30 and is positioned intermediate the sections or wings 24a and 24b of the flange 24. Intersecting vertically extending stiffening gussets 34 are formed in the bore or center portion of the support column 30 intermediate the top and bottom ends thereof for aiding in forming a sturdy, strong load carrying section in the leg 10. Such gussets are, of course, integral with the support column.
The lower flange 26 has a pair of apertures 36 therein for receiving securing means to attach the leg in operative association with the bed frame, and this flange 26 preferably is provided with an arcuate reenforcing center section or brace 38 that smoothly blends into the lower surface of this lower flange 26 and extends downwardly into a vertically extending portion of the leg spaced directly below the center portion of this lower flange 26. Such brace 38 may be hollow as indicated in FIG. 5 to reduce the amount of material required to form the leg without impairing the strength thereof.
The center support column 30 may include a vertically extending reenforcing rib 40 formed on the upper inner surface of this tubular support column while a socket 42, open at the lower end of the support column 30, for a caster stem and/or its positioning means is formed in the leg for receiving and completely encompassing suitable caster stems and caster stem socket positioning means. A conventional caster 44 is shown operatively engaging the lower end of the support leg 10 and having a caster stem (not shown) extending up into the caster socket 42 to position the same in operative engagement with the bed frame.
As clearly shown in the drawings, the flanges 24 and 26 have downwardly extending web means integrally formed therewith on adjacent laterally inner edges thereof and which reenforcing means form a substantially U-shaped section 46 that extends laterally of the bed frame leg and extends vertically downwardly of the bed frame leg a suitable distance so that the vertically extending leg 22 of the cross rail 14 can be received therein. These web portions or reenforcing sections in the support leg have horizontally aligned holes formed therein for receiving rivets or equivalent means 48 that extend through such holes and through holes in the vertical leg 22 of the cross rail 14 to affix the cross rail leg securely to the bed frame support leg. The horizontal flange 20 of the cross rail 14 is supported on the upper surface of this flange 26. The vertical flange or leg 22 is engaged on both sides by opposing surfaces of the U-shaped section 46 which snugly receive the cross rail leg therein to support it fixedly in position.
The support leg 10 is pivotally secured to the side rail 12, as by a rivet 50 or equivalent means that extends through preformed holes formed in the horizontal leg or flange 16 of the side rail, the horizontal flange 20 of the cross rail and through the lower flange 26 and holes formed therein. Usually a spacing washer 52 is carried on the shank of this rivet to aid in providing some spacing of the rails for pivotal action between the cross rail and side rail of the bed frame.
The cross rail 14 is further secured to the support leg 10 by a rivet 54 engaging a laterally inner portion of the support leg and the lower flange 26.
The outer appearance of the center support column 30 in the leg is made more attractive by the provision of vertically extending ribs 56 thereon and by gradually tapering the support column inwardly at its lower end. Likewise, reenforcing webs 58 are provided at laterally spaced lower margins of the reenforcing section 46 and they curve inwardly of the support leg and blend into one wall of the tubular support column.
FIG. 4 shows that when the support leg 10 is engaged with a cross rail and side rail in an operative bed frame, one end of the lug 32 at the upper end of the support leg abuts against the laterally inner edge of the side rail 12 when the cross rail is operatively positioned to extend perpendicular to the side rail.
It will be realized that all of the components and portions of the support leg 10 are of an integral, unitary construction and that the flanges 24 and 26 blend smoothly into the remaining portions of the leg and that the center support column 30 in the leg, as well as the other part of the leg are made of any suitable thickness from a high strength plastic moldable plastic.
The U-shaped reenforcing section 46 in the support leg forms one vertically extending wall 62 which is continuous from edge to edge in the leg whereas a wall 64 forming the opposed portion of this section may be interrupted as indicated at 66 in FIG. 5 of the drawings at the upper end of the support column 30 as a sturdy leg construction is still obtained.
A sturdy attractive leg has been provided by this invention. It is durable and meets the objects of the invention.
While one complete embodiment of the invention has been disclosed herein, it will be appreciated that modification of this particular embodiment of the invention may be resorted to without departing from the scope of the invention.
