In order to achieve the above object, the present invention and the lower frame of the rectangular shape disposed below; An upper frame disposed at a predetermined interval to face the lower frame via a plurality of coil springs; In the structure of the bed mattress consisting of a multi-layer outer shell surrounding the lower frame and the upper frame, the two longitudinal supports of at least one of the upper frame and the lower frame to support at least a portion of the body firmly At least one crossbar is provided in the width direction of the two longitudinal supports.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 4.

Figure 4 is a schematic perspective view showing a spring sag prevention structure of the bed mattress according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 4 to 8.

Spring sagging prevention structure of the bed mattress according to the present invention is, as shown in Figure 4, the lower frame 6 of the rectangular shape disposed on the bottom; An upper frame 8 disposed at a predetermined interval to face the lower frame 6 via a plurality of coil springs 9; In the structure of the bed mattress consisting of a multilayer envelope (not shown) surrounding the outside of the lower frame 6 and the upper frame 8,

At least one of the two longitudinal supports 8a or 6a of at least one of the upper frame 8 and the lower frame 6 in the width direction of the two longitudinal supports so as to firmly support at least a part of the body. It consists of a structure in which the crossbar 12 is installed.

Here, the at least one crossbar 12 may be arranged in one of a form perpendicular to its two longitudinal supports 8a or 6a, inclined at any angle and superimposed with an X, 12 may be made of plastic as well as a metallic material as long as it has a predetermined elastic force and workability.

Both ends of the crossbar 12 may be welded to the corresponding longitudinal support 8a or 6a, or may be fixed via a clip 10 ', or the crossbars 12 may be integrally formed at both ends thereof, respectively. It may be fixed to the corresponding longitudinal support 8a, or 6a via a hook 13 provided separately (see FIGS. 5-8).

In this case, when both ends of the crossbar are fixed by welding or clip type, both ends of the crossbar 12 are partially bent at a predetermined curvature, and then each free end is parallel to the axis of the corresponding longitudinal support 8a or 6a. It is preferred to be fabricated adjacent (see FIGS. 5 and 6).

Meanwhile, the crossbar 12 and the hook 13 may not only be integrally formed as shown in FIG. 7, but may also be formed separately from each other as shown in FIG. 8. The rear end 13 and the corresponding end of the crossbar 12 are releasably fitted to each other in a male and female form (for example, a coupling hole and a bent end, a screw hole and a corresponding threaded portion), or the hooks are made of plastic, and a crossbar. The metal may be fixed integrally through the insert molding method.

At this time, after the hook 13 is fitted to the longitudinal support 8a or 6a, the front end portion of the hook 13 is not pressed so as to prevent the crossbar 12 from moving along the axis of the longitudinal support. It is possible to limit the movement of the crossbar 12 to a minimum by using a distance between the clip 10 fixed to the pressing support or the longitudinal support (8a, or 6a) by using a.

On the other hand, the cross-sectional diameter of the crossbar 12 can be made larger or smaller according to the preference of the bed user for the upper and lower elasticity of the mattress, and the number of installation of the crossbar 12 is dependent on the preference or physical characteristics of the bed user It may be determined considering the hips, the waist, the back (or the chest), the shoulders, and the like.
