SPRING-HELD MATTRESS FOUNDATION SUPPORT STRUCTURE Filed July 25, 1962 32 n-3| l3 IO FIG- 2 INVENTOR JEROME A- GROSS United States Patent 3,116,495 SPRING-HELD MATTRESS FOUNDATION SUPPORT STRUCTURE Jerome A. Gross, 6304 S. Rosebury, Clayton, Mo. Filed July 23, 1962., Ser. No. 211,622 4 Claims. (Cl. 207
The present invention relates to bedstead constructions of the type employing angle-like rails to support a box spring or other foundation for a mattress.
Inasmuch as a precise fit between such mattress foundation and the rails which support it is not to be anticipated, and since flexureof rails is likely to occur in use, there is a possibility that such a mattress foundation may be dislodged sideward and fall between the rails. To avoid this possibility, heavy cross-slats have sometimes been placed atop of the rails, to extend crosswise between them. Such slats are undesirable for many reasons, such as the possibility that they may be dislodged, and the fact that they occupy a substantial part of the depth of the rails, holding the foundation so high so as to sacrifice part of the safety which the vertically extending rail flanges would otherwise provide.
A principal purpose of the present invention is to provide a readily attached spring-like clip which will fit closely atop of the horizontal flange of the rail and thus permit the supported foundation to fit well down within the vertical leg of the rail.
Further purposes are to provide a support structure which will furnish rigid support inwardly of the rails, which may be attached to the rail by a simple downward force, and will thereafter hold tenaciously to the rail.
These, and other purposes which will be manifest from the specification which follows, are accomplished in the present invention by afiixing spaced clips along each of such conventional beds rails, the clips being formed of springy sheet metal such as steel, each having a horizontal portion which extends inward of the rail and is there provided with a downward reinforcing flange. Such flange has a detent inwardly of the inner edge of the horizontal rail flange. The clip includes a portion of hairpin-like cross section bridging the vertical flange of the rail and terminating at its outer lower end in a detent which grasps the angular corner of the rail.
A preferred embodiment of the invention is shown in the accompanying drawing in which:
FIGURE 1 is a side view of a support clip embodying the present invention, in place on a bed rail shown in cross section. The dashed lines show its spread open position while being aflixed to the rail.
FIGURE 2 is a left end view of the structure shown in FIGURE 1.
FIGURE 3 is a right end view of the structure shown in FIGURE 1.
FIGURE 4 is a view in flat pattern of the spring clip of FIGURE 1. The dashed lines are bend lines.
The angle-like rail generally designated is one of a pair of conventional steel angles which extend between the head and the foot of a bedstead. Each such rail has a horizontal flange 11 which extends inwardly and terminates in a somewhat rounded inwardly presented edge 12. The rail has a similar vertical flange 13 terminating in a somewhat rounded upwardly presented edge 14. The flanges 11, 13 meet at a juncture having at its inner side a radius 15 and at its outer side a right angular corner 16.
In prior art use, wooden cross slats, not shown, are sometimes laid upon the horizontal flanges 11 to bridge between the pair of rails 10; these raise the mattress foundation substantially within the vertical flanges 13 3,116,495 Patented Jan. 7, 1964 and take away from their principal function which is to avoid sideward dislodgement of such mattress foundation.
The present invention requires only that small part of the height of the vertical flanges 13 as is occupied by a single thickness of sheet metal. Any fairly springy metal may be utilized; while the clip mentioned herein is referred to as being steel, other metals may be substituted.
The steel support clip, formed as shown in FIGURES 1, 2 and 3, includes a horizontal portion 21 which rests atop of the horizontal flange 11 of the rail 10, and extends from the rail radius 15 inwardly well beyond the rail edge 12, where it is divided into two inwardly projecting parts 22. In the embodiment shown, these parts 22 have adjacent downward reinforcing flanges 23, as shown in FIGURE 4, separated by a cut-out 26. This construction permits the unflanged width atop of the flange 11 to be relatively great, to minimize its bending deflectance.
Each reinforcing flange 23 has a side edge presented outwardly with respect to the bedstead, including two principal side edge portions: a detent portion 26, which in the assembled view of FIGURE 1 abuts the edge of the horizontal inner flange, and has the shape of a cutout; and a camming edge 27 leading from the bottom of the flange upwardly and outwardly to the detent portion 26.
FIGURE 4 shows the flat pattern of a sheet metal blank from which the clip 20 is formed. A tang-like portion 30 is an integral part of the horizontal clip portion 21. After blanking, the tang-like portion 30 is formed into a portion of hairpin-like cross section gen erally designated 31 in the other figures. It is narrow, as compared to the horizontal portion 21, which narrowness gives it easy deflectability.
Such hairpin-like portion 31 has an inner leg 32 whose bottom end fits into the radius 15 of the angle 10 and serves as a continuation of the structure provided by the horizontal portion 21. The hairpin-like portion 31 also includes an outer leg 33 which extends downward beyond the right angular corner 16 of the rail 10, where it is provided with an inwardly bent end detent 34, preferably having a lip 35 to facilitate sliding onto the rail flange 13. When attached, the inwardly bent end detent 34 grasps beneath the angular corner 16 as shown in FIGURE 1. The upper ends of the legs 32, 33 are connected by a bridge portion 36 which extends over the upper edge 14 of the vertical flange 13.
After the steel for the spring clip 20 has been cut to the form shown in FIGURE 4, the flanges 23 are bent along the bend lines a, b when the tank 30 is bent into the portion of hairpin-like cross section 31 as described.
To aflix the clip 20 to the rail 10, the portion of hairpin-like cross section 31 is pressed onto the vertical flange 13 of the rail 10; and the camming edge 27 of the reinforcing flange 23 is then pressed downwardly against the inwardly presented rail edge 12. This causes the hairpinlike cross section 31 to spread laterally, as shown in the dashed lines of FIGURE 1. Continued downward force results in seating the rail edge 12 within the detent cutout 26. When so seated, the clip 20 grasps the rail 10 tenaciously, and is not readily dislodged by any force encountered in normal use.
To illustrate the operation of the present invention, the extreme condition may be assumed: That the mattress foundation has shifted inward to exert a concentrated downward force on the inward parts 22 of the clip 20. Such concentrated forces on said inward parts 22 would tend to cause rocking of the clip 20 about its edge 12. The grasp of the inward bending detent 34 against the angular corner 16 resists upward movement of the hairpin-like portion 31. The greater width of the horizontal portion 21 gives it suflicient rigidity as to avoid bending deflection under such set of forces. Hence, even though the clip 20 is made of sheet metal, its unique design gives to it a ruggedness which withstands such loads. Two or three of the clips 20 so aflixed on each bed rail 10 thus gives secure support to a mattress foundation.
Variations in detail will occur to those familiar with the problems of the art. Accordingly, this invention is not to be construed narrowly, but rather as fully cextensive with the claims hereof.
I claim: 1. For use in bedstead construction and the like, a spring-held mattress foundation support structure comprising an angle-like rail having a horizontal flange terminating in an inwardly presented edge, and a vertical flange terminating in an upwardly presented edge, the flanges meeting at a juncture having at its inner side a radius and at its outer side a right angular corner, in combination with a support clip formed of springy sheet metal and havmg a horizontal portion resting atop of the horizontal flange of the rail and extending from the radius of the rail inwardly beyond its inwardly presented edge, the part thereof inwardly of said edge having a downward reinforcing flange, the flange having an outwardly presented side including a detent portion abutting the inner edge of the horizontal flange, the support clip further having a portion of hairpinlike cross section by whose springiness the detent portion is held abutting the inner edge of the horizontal flange, said hairpin-like portion extending over the vertical flange of the rail and fitting adjacent to its outer and inner surfaces and including an inner leg whose bottom end is a continuation of the horizontal clip portion,
an outer leg extending downward beyond the right angular corner of the rail and having an inwardly bent end detent by which the angular corner is grasped,
and a connecting bridge portion between the legs extending over the upper edge of the vertical flange of the rail.
2. A spring-held mattress foundation support structure as defined in claim 1, the detent portion of the reinforcing flange including a cut-out engaging the inner edge of the horizontal rail.
3. A spring-held mattress foundation support structure as defined in claim 1,
the outer side of the reinforcing flange having a camrning edge leading upward and outward to the detent portion,
whereby a downward force on the horizontal portion spreads the hairpin-like portion laterally to seat the inner edge of the horizontal rail against the detent portion of the supporting flange. 4. A spring-held mattress foundation support structure as defined in claim 1,
the horizontal portion of the clip which rests atop of the horizontal rail flange being of a greater width than the portion of hairpin-like cross section,
whereby to minimize the bending deflection of said horizontal portion and thereby utilize the grasp of the end detent against the angular corner to avoid rocking about the inwardly presented edge of the horizontal flange.
