By reference to Fig. 3J it will be seen border springs 6 receive rivets such as indicated that the described inverted U-shaped formation at 8 which are anchored in the horizontal ilange is produced by merely stamping the straps II and ai, of the border frame and serve to rigidly secure the withoutcutting or otherwise material weakening top coils of the border springs 6 to said border the same.

To prevent displacement of the anchoring straps I8, the end portions I9 thereof are bent downwardly and inwardly around the respective outermost ledges I6, as clearly shown in Fig. 2. Such bending of the ends of the straps I8 may easily be accomplished manually and it may be facilitated by providing holes I 9B in the ends of the straps in the zone of bending thereof. The anchoring straps I8 thus not only serve to lock the coil springs to the straps II, but also to prevent spreading thereof.

The straps I I which overlie adjacent marginal portions of adjacent spring rows are resiliently connected together by means of helical springs 20, 20 of suitable length and formed with hooks which may conveniently be engaged with the eyelets or tubular rivets I3, I3.

'Ihe ends of each of the straps II are resiliently connected by means of helicals such as indicated at 2I with the border springs 6 which are aligned with the respective rows, the top coils of such aligned border springs being preferably formed with ears or loops 22 which facilitate the connection of the springs 2I to said border springs 6 and serve to maintain said helicals 2| in predetermined position substantially in axial alignment with the lengths of the marginal straps I I. As indicated, the helicals 2l are provided with hooked ends which engage the ears 22 of the border springs 6 and which engage suitable openings, such as indicated at 23, in the adjacent ends of the straps II.

The cross members I2 of the outermost rows of springs 9 are provided with outwardly projecting end extensions 24 and said extensions are provided with openings indicated at 25. Helical springs 26 provided with hooks at their opposite ends are stretched between the end extensions 24 of the cross straps and adjacent side border springs. Since the cross straps I2 are located intermediate the springs of each row, it is convenient to connect the sides of the outermost rows to the side border springs by means of coil springs 26 arranged in pairs, the springs of each pair being arranged in diverging relation, as shown.

Any suitable form of body support may be provided. Inasrnuch as the present invention is concerned only with the top construction, no bottom structure is illustrated but it will-of course be understood that there is associated with the border frame5 a main supporting base frame which carries suitable cross straps or other means for supporting the lower ends of the coil springs 6 and 9.

The described structure may be advantageously used in combination with inner spring mattresses, especially for the reason that ample top surface area is provided to adequately support the springs of an inner spring mattress. Because of the comparatively small spaces intervening between ad jacent portions of the various straps, it is not possible for the springs of an inner spring mattress to become displaced because of lack of support. Although there is adequate support provided as explained, the bed spring is nevertheless resilient so as to avoid impairment of the` comfort qualities of an inner spring mattress. The straps II being ilexible metal straps, permit localized bending to conform to localized weights applied to the bed spring, and inasmuch as the rows of springs 9 are resiliently supported by means of the connecting helicals 20, 2l and 26, they may shift transversely or longitudinally or in a lateral direction, as may be required, as an incident to localized compression of the mattress. The metal strap elements II, I2 and I8 are of sufficiently strong but quite thin material so as to avoid the addition of an objectionable amount of weight to the bed spring structure. All of the said elements are to be understood as being of suilicient flexibility to permit bending and yielding under the application of localized pressures.

Changes in the described structure may be made without departing from the spirit oi the invention, the scope of which should be determined by reference to the following claims, the same being construed as broadly as possible consistent with the state of the art.
