April 20, 1954 c. B. COLSON TUBULAR BED LEGS FOR COIL SPRING ANGLE RAILS Filed April 27, 1950 v INVENTOR. m 15 60/600 A V III III A I I a": an
Patented Apr. 20, 1954 UNITED STATES PATENT OFFICE TUBULAR BED LEGS FOR COIL SPRING ANGLE RAILS 5 Claims.
The present invention constitutes an improvement upon my presently co-pending application for Letters Patent, entitled Hollywood Bed-leg Clamp, filed June 28, 1948, S. N. 35,603, and has for its prime object, the provision of a non-adjustable, sturdy, yet simple construction adapted to rigidly secure a suitable length of tubular metal to the angle rail of a coil spring bed, thereby forming a so-called Hollywood bed, to the end that those advantages of use, convenience, and economy which attach to the Hollywood bed may be better enjoyed.
An advantage of the present construction over the above referred to co-pending application for patent, resides in the fact that the whole of the leg assembly is formed of metal, the leg portion thereof being slotted to receive the vertical leg of the angle rail of a bed spring, and, which angle rail is fixedly clamped to the bed leg so as form an exceedingly strong union thereof so as to withstand the romping, and in general, the rough usage to which the Hollywood bed generally lends itself.
Other objects of the invention, as well as features and advantages thereof may be noted from a study of the accompanying drawing, the detailed description and the subjoined claims.
In the drawing:
Figure 1 is a utility view showing application of the invention to the angle-rail of a standard form of bed.
Figure 2 is a top-plan view of the device of this invention applied to a fragment of a bed angle-rail; and,
Figure 3 is a mid-sectional elevation taken along line.33 in Figure 2 showing detailed construction of the means used to secure a bed-leg to the angle-rail of a bed spring.
Figure 4 is an elevational view of a fragment of the inner side of an assembled bed-leg structure.
Figure 5 is a top-plan view of a bed-leg per se; while,
Figure 6 is a side-elevational view showing the upper, slotted end of the bed-leg per se.
Figures '7, 8 and 9 are respectively views in plan, side-elevation and end-elevation of the detachable clamping member adapted to secure the angle-rail within the slot in the bed-leg.
As shown in Figure 1 of the drawing, the bedleg I of this invention is adapted to form one of a plural number of like formed supports for a bed spring 2, and when combined with a bed spring, are adapted to substitute for a standard bed-stead.
The bed-legs I are formed of tubular metal cut to an appropriate length, generally 10 inches, and are die cut, or otherwise processed to have a slot 3 in one end of such length as to receive the vertical leg 4a of an angle-rail 4 of the bed spring 2, and of such width as to also accommodate the leg 4a aforementioned, and it is to be noted that the upper corners of the slot 3 are formed with a radius 5 so as to create a shoulder which is adapted to rest against the fillet of the angle-rail, so that in practice the horizontal leg 41b of the angle-rail will lie fiat upon the upper free end of the bed-leg I.
A pressure plate 6 formed of strip metal stock is adapted to lie across the angle-rail .4, and as shown in the drawing is formed with a rectangular front portion 1, while the inner end is formed with fingers 8, 9, and Ill. The central finger 8 is formed with a flanged end 8a which is adapted to rest upon the inner top surface of the leg I, while the fingers 9 and I0 are formed with flanged ends 9a and lim which rest in contact with the inner surface of the leg I.
The pressure plate 6 is also die punched to a provide a slot ll therein, and the metal thus displaced forms a tab I2 which is bent downwardly at right angles to the under-surface of the plate 6, and is adapted to lie against the inner face 40 of the leg 4a of the angle-rail. Thus it will be seen that the pressure plate, as shown in Figures 2, 3 and 4, is centered against drift when in functional position.
The inner side of the leg I is pierced to form a bayonet slot l3 to admit insertion of a bolt I4 to within the leg for upward extension therethrough, and is adapted to be extended through the slot II in the pressure plate to receive a wing-nut I5 as shown in Figures 3 and 4. Attention is directed to the fact that the bolt I4 is deformed to provide a knuckle I6, the medial convex surface of which is in contact with the inner side of the tubular leg I, and is adapted to form a fulcrum point for vertical alignment of the bolt in assembled position so as to hold the head I! thereof in flush contact with the outer face of the leg as illustrated in Figure 3.
The bed-leg and the bed-spring rail are brought into assembly by first slipping the bolt it in war-oily through the bayonet slot it with the shank thereof extending upwardly through the interior of the bed-leg with the bolt head ii in flush contact with the exterior surface of the leg as shown in Figure 3, thereafter, the leg 4a of the rail e is slipped into the slot 3 in the leg and the pressure plate 6 is placed upon the rail 4 with the free end of the bolt is extending through the aperture H in the plate and with the flange 8 upon the inner surface of the leg and with the fingers 9 and Ill in abutment with the inner adjacent surface of the leg. When the plate is thus posititoned, the tab l2 will of necessity rest upon the inner face 40 of the rail 5. The Wing-nut I5 is secured to the threads of the bolt which when tightened securely holds the rail and the leg in detachable union.
It is to be noted, as best illustrated in Figure 3, that the length of the flanged end 8a of the finger 8 is of such length as to cause the plate 6 to lie in a slight degree of angularity across the leg 4b of the rail so that the free corner portions Iic-'6d of the plate rests upon the rail at a point outwardly of the longitudinal center thereof. This construction provides a degree of adjustability in tightening the bolt M in functional position and insures that screw threaded pressure'exerted upon the plate and the rail is constant and that the wing-nut is not apt to back-01f from tightened position.
It is also to be noted that this construction provides against tilting of the plate and that it accommodates slight surface imperfections in the respective adjacent faces of the parts concerned, for the reason that the corners 6c and 6d of the plate and the finger 8 represent triangularly disposed point from which the plate 6 bridges the rail, and that inherent stability against tilting is derived therefrom. It is also to be noted that the triangular disposition of the fingers 9 and l 9 and of the tab 12 with respect to one another, insure against lateral drift or movement of the plate 6 in any direction.
It is submitted that the construction herein shown and described is novel in the art and that it constitutes an advance therein because of its novel simplicity, eificiency, strength and ease of installation and low cost.
Having thus described my invention in its presently preferred form, that which I believe to be new and for which I seek Letter Patent is as follows.
I claim:
1. The combination in a bed-spring having an angle rail base, of a plural number of metallic legs located on said angle rail base for support of said bed-spring in elevated horizontal posim tion, said legs being tubular and having a slot in one of the ends of each thereof receiving a dependent flange on said angle rail so as to form an outer and an inner side thereon, said legs be ing formed with a bayonet slot on their inner sides, a pressure plate for each of said legs, said pressure plates each being in acute angular contact with said angle rail and being formed with a trichotomous flanged inner end, the central fork of which is aligned with and which bears upon the upper end of a corresponding tubular leg and the outer forks of which are in abutting contact with the inner surface of said corresponding tubular leg, each of said pressure plates being formed with an aperture extending therethrough, a tab, said tab being dependent from said plate adjacent said aperture, and being so located upon the pressure plate as to be in abutting contact with an inner face of said angle rail, the flanged outer forks of a single plate and the tab thereon 7 structural elements of the plate resistant to drifting thereof in functional position, and an L-bolt for each leg formed with a knuckle intermediate its right-angle bend and its threaded end so as to form a fulcrum point thereon, each bolt being anchored in a bayonet slot and extending upwardly through a corresponding tubular leg and pressure plate, the knuckle of eachv bolt being adapted to cause the head of said bolt to lie in flush contact across said bayonet slot when a nut is applied to the bolt for pressurizing said plate upon said angle rail.
