BED SPRING I Filed June 11, 1948 Patented Apr. 11, 1950 UNITED STATES PATENT OFFICE BEDSPRING Alfred R. Gyles, Liberty Grove, Md.

Application J une 11, 1948, Serial No. 32,365

7 Claims.

My invention relates to bed springs, and more particularly to a bed spring comprising a pair of vertically-spaced frame members spanned by horizontally-disposed suspension members and including a plurality of individual springs interposed between the frame members and/or the suspension members to resilently support the frame members in verticallywspaced relation. Particularly, the spring according to the invention comprises a flexible mattress-supporting surface which is yieldable at substantially any point, whereby to permit the spring and mattress to conform to the contours of a person resting thereon.

With the foregoing in view, it is an object of my invention to provide an improved bed spring of the class described.

A further object is to provide an improved bed spring which includes a plurality of spaced individual springs connecting upper and lower frame members, said springs being xed to one frame member and slidable on the opposed frame member.

Other objects and advantages reside in the particular structure of the invention, combination and arrangement of the several parts thereof, and will be readily understood by those skilled in the art upon reference to the attached drawing in connection with the following specification, wherein the invention is shown, described and claimed.

In the drawing:

Figure 1 is a fragmentary plan view of a bed spring showing the invention applied thereto;

Figure 2 is an edge elevation thereof;

Figure 3 is an enlarged perspective view showing the individual spring structure;

Figure 4 is a fragmentary elevational view showing a supplemental spring element;

Figure 5 is a View like Figure 4, but taken at right angles thereto and with parts broken away and shown in longitudinal vertical section;

Figure 6 is a horizontal sectional view taken substantially on the plane of the line 6 6 of Figure 5;

Figure 7 is an enlarged fragmentary vertical sectional View showing a detail of the spring element of Figure 3.

Referring specilically to the drawing, wherein like reference characters have been used throughout the several views to designate like parts, I0 designates generally a bed spring according to the invention which comprises an upper rectangular frame Il and a similar lower rectangular `frame I2. Each frame II and I2 is connected together by a plurality of spaced transverse suspension members I3 which are preferably parallel to each other. Likewise, each frame includes a plurality of longitudinally-extending suspension members I4 which are likewise spaced and parallel. The suspension members I3 and I4 cross each other to provide intersections I5. As best seen in Figures 3 and 7, the suspension members I3 and I4 are of channeled Configuration to provide horizontally-disposed webs I6 and vertically-disposed side flanges I'I. As best seen in Figure 7, at each intersection l5, the side iianges Il of one of the suspension members are cut away to provide aligned notches I8 receiving the intersecting suspension member therein with the webs I6 of the intersecting members abutting. Preferably, the formation of the notches I8 is staggered at alternate intersections I5. Thus, at one intersection I5, the notches will be formed in a longitudinal suspension member I4, while at the next intersection of the same longitudinal member I4, the notches will be formed in the transverse suspension member I3. However, in the vertically-aligned intersections I5, and as clearly shown in Figure 3, it is preferred that the notches I8 be not alternated. Thus, in Figure 3, the notches I8 are formed in the longitudinal suspension member I4 in both instances. This structure permits vertical exing at each intersection I5 in both the upper and the lower frame. However, by alternating the notches at alternate intersections, no one set of suspension members is materially weakened and, also, each suspension member is flexible despite its channeled configuration at one 0r more points along its length. Moreover, it is preferred that the abutting web IB at each intersection I5 be iixedly secured together in any suitable manner, as by being spotwelded to each other and/or riveted to each other.

Each intersection I5 of the upper suspension members I3 and i4 has secured to the under side thereof the apex of an inverted V-shaped spring I9. Said spring has a pair of downwardlydiverging legs 2I`, the free ends of which are slidably received in the upwardly-directed channel of a suspension member I4 of the lower frame. Likewise, at each intersection I5 of the lower suspension members there is secured the apex of a substantially V-shaped spring 20. The springs 23 are identical to the springs I9 except for their reversed position and include diverging legs 22, the free ends of which are slidably received in the downwardly-directed channels of the transverse upper suspension members I3. Thus, the springs I9 and 20 are offset to a degree 3U are staggered in adjacent suspension mem-- bers I4 whereby there is a spring 30 between every,-

other pair of adjacent intersections I5. Obviously,

instead of placing the auxiliary springs 3D. on the:

longitudinal suspension members, they could be located on the transverse suspension members I3 or partially on the transverse suspension members and some on the longitudinal frame members. The auxiliary springs 30 lare best seen inl Figures 4, 5 and 6, and comprise an upper sleeve 3| including an upper end interposed between the flanges Il of an upper suspension member I4. and pivotally connected to such flanges by means of a horizontally-disposed pivot 32 spanning such flanges. The sleeves 3| may be rectangular in cross-section, as shown, and opposite sides thereof are provided with longitudinallyextending slots 33. plementary to the sleeve 3|, is slidably received therein. Each plunger 34.includes a lower end extending axially outwardly of the sleeve 3|. Such lower end is pivotally connected between the flanges Il of a lower suspensionmember i4 by means of a pivot 35 spanning such flanges. Each plunger 34 includes a pair of laterally oppositely-directed lugs 36 which are slidable in the slots 33 of the sleeves 3|. A compressive coil spring 3l is interposedbetween the upper end 4of each plunger 34 and the pivots 32 for the sleeves 3|. The upper and lower ends of the sleeves 3| and the plungers 34, respectively, are. ipreferably rounded, as at 38 and 39, and, as= shown, in View of the fact that the pivots 32 and 35 are parallel, limited lateral displacement of the upper frame l and lower frame I2 is permitted by the arrangement.

It follows from the foregoing that each upper and lowerframe includes intersecting suspension members of .channeled configuration, whereby the suspension members are rigid between thev Thus, each suspension member comprises alternate rigid and vertically-flexible por tions, each intersection comprisesa rigid por-- notches I 8.
