LOUIS E. FREY FIG. 3

United States PatentO 3,166,894 SPRING CONSTRUCTION Louis E. Frey, 382 Fairway, Wichita, K2215. Filed Jan. 9, 1962, Ser. No. 165,131 6 Claims. (Cl. -243) This invention relates to foundation means and in a more specific aspect to a spring means for a bed or the like. In a still further specific aspect, the invention relates to spring means for a bed or the like which is constructed to receive and hold thereon a mattress or similar article and wherein the various portions of the spring means are independently compressible in response to a weight placed thereon in use.

Various types of spring means are known including spring means for a bed or the like. In the prior art bed spring constructions, the individual springs are tied together lengthwise and transversely to provide the necessary unitary structure and in many instances a relatively heavy metallic member or tie wire extends around the entire spring unit. The spring means for beds and the like of the prior art are covered or enclosed by suitable fabric cover means and in some instances resilient pads or ele mentsare positioned between the cover means and spring units. In the prior art constructions, the individual springs or portions of the entire bed spring are not individually compressible but a load or weight placed on one portion of the bed spring causes depression of all the surrounding portions thereof and a result improper and uneven support is provided for the supported article or individual and gives rise to a hammock-like effect. In

en base member which is positioned on and supported i by the slats and extendsvtrans'versely relative thereto.

' ports are provided and each of the spring units has one of the pad supports positioned on the top convolution i addition, the prior art spring constructions arenot only inefficient in supporting a single body on a bed or the like but when two or more people are reclining on the bed the center portion of the spring unit is relatively heavily weighted and the edge portions thereof are relatively lightly weighted which tends to cause the individuals on the bed to be urged toward the center portion of the bed. Furthermore, movement by one person on one portion of the bed is easily transmitted through the spring means to the other portion of the bed which is undesirable, particularly where one or both parties are light sleepers.

In accordance with the present invention, foundation means for a bed or the like has been provided which eliminates the deficiencies of the prior art constructions. The foundation means of the invention includes support means. Spring means are provided and carried by the support means. Cover means separately cover each of the spring means.

In a preferred specific embodiment of the invention,

a bed spring is provided which includes a rectangular open wood frame having two spaced and generally parallel side members joined at the ends totwo spaced and generally parallel end members. gated boards are provided and each of the side members has one of the boards secured thereto along the inside lower edge portion thereof and extending substantially the entire length thereof to provide oppositely disposed ledges positioned in mirror image relation. A plurality of slats or support means are provided and extend transversely across the frame in spaced and generally parallel relation with the end portions of the slats resting on and supported by the ledges. The frame includes .a ledge or border portion around the upper edge thereof which extends inwardly and a pad of resilient material is provided and is positioned onthe ledge or border member andis of size to substantially cover'same. A fabric frame cover is provided and is secured to the frame to cover the inner edge of the ledge or border portion, side surface of the side and end members. A plurality of elongated spring units or elements are provided and are positioned. within the frame and preferably extend Two narrow and elonthe pad and the out- A plurality of coil springs are provided and each of the spring units or elements has a plurality of the coil springs secured to the base member and the springs are longitudinally aligned therealong.

coil springs therein. A plurality of elongated pad sup of the coil springs and elongated pads of resilient material are positioned on or secured. to the pad supports. Preferably a stretchable ticking fabric is provided for each of the spring units and the spring units or elements are individually covered and enclosed. The separately covered spring units or elements are individually compressible in use in response to the load placed'on each of the units and compression or depression of one of the units does not cause movement of the adjacent ones thereof. i I

In another preferred specific embodiment of the invention, an open frame is provided which has two spaced side members positioned in generally parallel relation joined at the ends to two spaced end members which are also in generally parallel planes. Ledges means are formed on the side members mirror image relation, preferably by a board orthe like secured to the lower edge portion of the side members and extending substantially the entire length thereof. A plurality of slats or support means extend transversely across the framein spaced and generally parallel relation with the end portions of the slats resting on and supported by the ledgea. The frame includes an outer border or ledge portion of resilient or spring elements which are compressible and wh ch are positioned at the outer periphery of the hen spring unit. The border portion of the spring includes a base. member which is supported by the frame and the provided and is supported by the coil springs and extends entirely around the border portion. A pad of resilient material or the like is positioned on the pad support and extends around the border portion. Cover means encloses and completely surrounds the border portion of the foundation. A plurality of elongated spring units or elements are provided and positioned within the frame and extend from one of theend members to the other of the end members with the spring units being supportedby the slats.
