Mattress edge protection spring and mattress

[0016] DETAILED DESCRIPTION The following embodiments of the present invention to create described in further detail.

[0017] like Figure 4 The mattress comprises a spring layer 20 shown mounted on a plurality, such as four side walls 20 spring layer figure 1 Edge protector spring 10 shown. Edge protector 10 consists of a spring wire wound integrally formed. Top edge protector spring 10 and the bottom edge of a spring layer 2 are fixed at 20 (see Figure 4 ) Top and bottom side walls. like figure 1 , The top edge guard spring 10 is connected between the edge 21 and the bottom portion 3 connected to elastic, elastic connector portion 3 includes a left and a right elastic connecting portion 31 elastically connecting portion 32. Left elastic portion 31 connecting the left and top edge of the left end of a bottom 2 connected together, the elastic connecting portion 31 left middle right arches. Right elastic portion 32 connected to the right end of the top edge and bottom edge of a right end 2 are connected, the central arch 32 left and right elastic connecting portion. Thus, the left, the presence of the angle between the upper half and the second half of the right and left elastic portions 31, 32 are connected, so that there is resilience between the deformation and the second half of the upper half. 1 when the top edge is pressed downward by compressing the left, 31 and 32, the right upper half is pressed down while the elastic connecting portion is close to half, so that the angle between the two narrow, when the top edge 1 They are no longer being squeezed, the right and left upper half of the elastic connecting portion 31 is no longer being squeezed away from the lower half of it to the initial position, so that the angle between the upper and lower half half returned to The initial angle. Left, right middle dome 31, the elastic connecting portion 33 has two turns around the ring, so the left can be increased, and the deformation between the upper half of the right half of lower connecting portions 31 and 32 elastically resilient. like figure 2 or image 3 , The left, middle and right elastic connecting portions 31, 32 are not located in a top edge and a bottom edge 2 where both 1 and biased towards one side on a plane. Such as Figure 4 In the mounted state, the left, middle and right portions 31, 32 connected to the resilient inner spring bias layer 20. After installing the mattress edge protector spring 10, the fabric covering layer (not shown) on an outer surface of the spring layer 20, thereby assembled into a complete spring mattress. When the person sitting in the spring mattress edge, a top edge 10 of the spring retaining edge is pressed downward by a compression elastic connecting portion 3, since the elastic connector portion 3 toward the inside of the mattress, even when the retaining spring 10 is compressed and the edge projecting deformation, it will only protrude inward mattress, the mattress does not bulge to the outside.

[0018] As described above merely embodiments of the present inventions, it is not defined in this patent scope. Those skilled in the art to make insubstantial changes or replaced on the basis of the present inventions, still fall within the scope of patent protection.
