Thepresent inventionrelates to a bed or couch spring and particularly to a bed or couch spring provided with side strengthening members.

In bed springs heretofore used, attempts have been made to impart extra .rigidity to the side members to prevent excess sagging when someone sat on the edge of the bed. However, none of these attempts have been entirely successful. By constructing a bed spring which embodies the present invention the resulting structure will be one that has extra support applied to theside member-step thatgifvsomeone sits on the edge of the bed it will not sag abnormally. The-added rigidity, however, in no way interferes with .the overall comfort ,in the normal utilization. of the bed spring.

Another object of the present invention is to provide a pair ,of side members and supports therefor that will prevent thelside members from movinginwardly and thereby contracting the total supporting surface available for the mattress. A bed spring embodying the present invention presents a supporting surface that extend the full width of the supporting cross pieces for the bed spring at the head and foot of the bed.

It is another object of the present invention to provide a bed spring that will, in use, have a much greater chance of preventing a surface that will catch a sheet or mattress and cause it to tear, from coming into contact with said sheet or mattress.

One feature of the present invention is the use of a plurality of suspension springs for supporting the side strengthenin members, and the fact that these suspension springs do not all lie in the same horizontal plane. Some of the supporting springs that are secured to the side strengthening member lie in the same horizontal plane as the side strengthening member and others lie in a plane at an angle with the plane side strengthening members. This greatly increases the tension force available to securely hold the side strengthening members in position, and contributes toward the attainment of the objects of the present invention above listed.

These and other objects and advantages of the present invention will be more readily understood from the following description and drawing of one specific embodiment of the present'invention, in which drawing:

Fig. 1 is a plan view of a bed spring embodying the present invention;

Fig. 2 is a side elevation thereof;

Fig. 8 is an enlarged plan view of a corner of a bed spring embodying the present invention;

:The-;-bedsspring:has:theusual; rigid. frameieonsisting of transverse supporting :members :10; at the head anidifoot, and-the.longitudinaliitubular member-ll to which. theztransversezmember It is secured. v

'lIlhezsidezstreng'thenlng members 12 are secured to the -;transverse supporting members :16 by means of ,a plurality of .helical springs. These springs consist of two group he p ings 1-3. which-lie inthe horizontalplane, v andsthe springs l4 which-liein-a plane-at anangle with the horizontal. The, rigid partof the side strengthening member .12 is the angle'iron IS. The angle iron 15 isbent at its ends ,to form the short segments l6 parallel tothe transverse supporting members I0. Rivettedto the ends ofthe shortsegments l6, and connecting both of them, is metal strip IT. The strip I1 is much Wider in the horizontal plane than it is thick in the vertical plane. Thus the strip [1 will be resilient in the vertical plane but not in the horizontal plane.

Located within the side'strengthening member I2 is a resilient supporting structure as is found in many bed springs comprising the cable 3 held under tension by helical springs I9, hooked to the short segments l6, and secured to the angle iron l5 by clips 20, and to the metal strip I1 by the clips 2|; of course a conventional link structure may be used.

As can best be seen in Figs. 3 and 4, the helical supporting springs l3 and M for the side strengthening member l2 are hooked into opening 22 in the transverse supporting bar It and into

openings

23 and 24 in the segment it of the angle iron l5. The openings 23 in the horizontal portion of the angle iron l5 secure the horizontal springs l3 and the opening 24 in the vertical portion of the angle iron 15 support the springs l4.

Since there are a plurality of springs 13 and H3 securing the rigid angle irons l 5 to the transverse supporting bars It, the sides of the bed spring will be greatly strengthened. Moreover, the fact that the springs I4 do not lie in the horizontal plane adds greatly to the amount of force it will take to force the sides of the bed spring downwardly ince they will react to a vertical force primarily by expanding along their longitudinal axis rather than bending, as will springs in the horizontal plane.

The structure as shown in Figs. 3 and 4 is repeated at all four corners of the bed spring. The central portion of the bed spring may comprise the conventional cable structure 25, as shown, or a conventional link structure secured to the supporting bars by helical springs. As best seen in Figs. 3 and 5, the central cable structure 25 is linked to the cable I8 by the clips 2|.

Since the corner 26 is rounded due to the fact that the angle iron 15 is bent at right angles to form the segment 16, no sharp corner is presented that will tear sheets, or a mattress. The conventional angle iron at this point has a very sharp corner that is prone to tear sheets and mattresses.

I claim:

1. A bed spring comprising a rigid frame, two side strengthening parts, each of said side strengthening parts comprising a rigid member having a long portion extending substantially from one end of the spring frame to the other and terminating at each end in a short horizontal portion at right angles to said long portion, a plurality of groups of springs securing each end of said side strengthening parts to the rigid frame, and a bed sprin cable structure interposed between said two side strengthening parts and secured to the rigid frame, said bed spring including a rigid metal strip connecting the ends of the short portions of each side part.

2. A bed spring comprisin a rigid frame, two side strengthening parts, each of said side strengthening parts comprising a rigid member having a long portion extending substantially from one end of the spring frame to the other and terminating at each end in a short horizontal portion at right angles to said long portion, a plurality of groups of springs securing each end of said side strengthening parts to the rigid frame, and a bed spring cable structure interposed between said two side strengthening parts and secured to the rigid frame, said bed spring including a strip connecting the ends of the short portions of each side part, and a second bed spring '4 cable structure secured to the side strengthening parts between the long portion of the rigid member and the strip.

3. A bed spring comprising a rigid frame, two side strengthening parts, each of said side strengthening parts comprising a rigid member having a long portion extending substantially from one end of the spring frame to the other and terminating at each end in a short horizontal portion at right angles to said long portion, a plurality of groups of springs securing each end of said side strengthening parts to the rigid frame, and a bed spring cable structure interposed between said two side strengthenin parts and secured to the rigid frame, said bed spring including a strip connecting the ends of the short portions of each side part, and a, second bed spring cable structure secured to the side strengthening parts between the long portion of the rigid member and the strip, said second bed spring cable structure being linked with the first mentioned bed spring cable structure.
