1 Claim. (Cl. 5-264) This invention relates to bed springs and is more particularly directed to improved means for mounting the supports for individual conical helical bed springs.
One of the objects of the invention is to provide a rectangular frame for a bed spring in which the supports for the conical helical springs are disposed at an angle or transversely to the longitudinal axis of the frame so that the weight of the person reposing thereon is more evenly distributed over each of the supporting means.
Another object of the invention is to provide a support for the conical helical springs of a bed spring that will enable more of said springs to be installed within the bed spring frame.
The invention consists in the provision of a rectangular bed spring frame in which the straps or wires to which the conical helical springs are secured, are disposed at an angle less than 90 degrees ortransversely to the longitudinal axis of the frame and in which the unsupported ends of the springs are suitably bound, the supported ends of the springs being further supported by wires passing through the aligned ends of said supported ends and disposed parallel to the sides of the rectangular frame.
In the drawings:
Fig. 1 shows a plan view of my improved bed spring,
Fig. 2 is a sectional view taken along the line 2-2 of Fig. l,
Fig. 3 is an enlarged sectional detail view taken along the line 3-3 of Fig. 2,
Fig. 4 is a detail view showing the mode of mounting the perimeter springs,
Fig. 5 is a sectional view taken along the line 5 5 of Fig. 1,
Fig. 6 is a perspective view of the detail shown in Fig. 3,
Fig. 7 is a perspective view of the form of spring mounting for the perimeter springs,
Fig. 8 is a modified form of spring mounting,
Fig. 9 is another modified form of spring mounting,
Fig. l is a perspective view of the mounting shown in Fig. 8,
Fig. 11 is a invention; and
Fig. 12 is an enlarged side elevational view of the spring mounting shown in Fig. 11.
The bed spring comprises a rectangular frame 1 made up of an angle iron, and substantially midway of the length of the longer sides of the rectangular frame is secured a bar 2 for reinforcing the frame. A plurality of supporting members or straps 3 are supported from the sides of the rectangular frame and transversely or obliquely disposed to the longitudinal axis thereof at an included angle less than 90 degrees. Each strap 3 is twisted at its ends for securement to the sides of the rectangular frame. The straps crossing the reinforcing bar 2 are secured thereto and, at the point of crossing, are twisted so that they may be clamped to the bar. If desired, two short length straps may be substituted for continuous straps. These straps are disposed on their edges between the bars of the rectangular frame and constitute a support for the smaller end of each of the conical helical springs 4. The smaller ends of these springs are disposed in suitable slots cut in the upper edge of straps 3. The large upper ends of the springs are bound by small extension springs 6 tied to the uppermost turn of springs 4. A binding wire 7 is plan view of another modified form of the ICC disposed above and in parallel relation to the rectangular frame and to which the upper turn of each of the springs 4 disposed on the perimeter of the rectangular frame is secured at the point of tangency of each of the springs 4 with the binding wire 7 for the purpose of preventing sagging of the upper edge of the bed spring.
A plurality of wires 8 are disposed parallel to the sides of the rectangular frame and pass through the lowermost turns of the springs and through an aperture 9 in straps 3. The ends of these wires have a hook 10 formed thereon for the purpose of limiting the relative movement of each of the springs 4 and wire 8 with respect to the frame. The springs 4 disposed about the perimeter of the frame 1 may have wire 8 bent to pass under the attened part of straps 3 instead of passing through a perforation, as shown in Figs. 3 and 6.
The several springs 4 secured to straps 3 are so arranged that they form rows parallel to the sides of the rectangular frame. The transverse arrangement of each strap enables more springs to be assembled in the frame as well as providing for more uniform distribution of the load on the straps. The person lying on the bed spring illustrated will have his weight supported by the straps at a plurality of points along the sides of the frame, thus preventing sagging of the springs.
The form of spring mounting shown in Fig. 7 is employed for the perimeter springs in which the ends of the fiat ends of straps 3 have wires 8 looping under the straps and over* the first turn of springs 4, and the lowest turn of coil springs 4 is disposed under wire 8 and over the straps.
A further modification is illustrated in Fig. 9 in which straps 11 are suspended from the frame 1 by means of resilient elements or extension springs 12, each suitably hooked in one of the legs of the angle iron of frame 1, its other end being hooked in strap 11. These straps are disposed vertically between the sides of frame 1, springs 4 being supported on straps 11 by threading the lower ends thereof into suitable apertures cut in straps 11.
Another modified construction is illustrated in Figs. 8 and l0 in which a wire 13 is supported transversely of the frame 1 and in which the lower ends of springs 4 are threaded about an indentation or kink 14 in the wire. The wire 13 has hooks 16 formed on the ends thereof and received in apertures in the frame 1. A binding wire 15 is disposed in the apex of the kink and about the lower turn of springs 4, thereby holding spring 4 in position on the supporting wire 13.
Fig. 11 shows a plan view of a modified bed spring in which a portion of the rectangular frame 17 is shown and is constructed similarly to frame 1 described above. A plurality of straps 18 are disposed transversely across the frame and each strap is suspended from the sides and ends or from the cross bar 19 by resilient elements or extension springs 20, the end loops on each spring being inserted in suitable apertures in straps 18 and in the sides and ends of frame 17.
A plurality of conical helical coil springs 21 are mounted on the straps and each spring is supported on the strap by threading the lowermost turn (Fig. l2) into suitably spaced apertures 22 cut in the straps. The upper or larger end of each spring 21 is connected by extension or tying springs 23.
rl`he threaded support for the lower end of springs 21 constitutes the sole support for the springs. These springs do not depend upon adjacent springs for load support except as they are affected by the tying springs 23. The individual support for each conical spring plus the yield of springs 20, results in greater comfort and more strict conformity of the bed spring to the body contour of the person reposing thereon. The wires 8 shown in Figs. l7 are eliminated in this form of the invention since each spring 21 is individually supported.
What I claim is:
A bed spring comprising a frame having parallel sides and ends, supporting members disposed in spaced relation within said frame and extending in the same direction at substantially similar oblique angles with said sides and ends, rigid means connecting said supporting members and said sides and ends, coil springs distributed in spaced relation within said frame above said supporting members, means securing one end of each coil spring to a supporting member, said securing means penetrating said supporting member, said frame further comprises a reinforcing bar extending across said frame between said sides, and certain of said supporting members being connected by said connecting means to said bar.
