Description

Spring pads connected by elastic spacers Technical Field

[0001] The invention discloses a spring pad, which belongs to the technical field of household articles, and in particular relates to a spring pad connected by elastic interlayers. Background Art

[0002] Products in the prior art, such as mattresses and sofa cushions used in bedding, sofas and other products, use too much sponge, latex cotton and other materials. The rebound force can meet the requirements for short-term use, but it is easy to deform, partially collapse and weaken the rebound force after frequent use for a few years. Continuing to use will affect rest and health. Even if it is eliminated, it will cause a waste of resources. On the contrary, mattresses made of harder materials such as coconut palm will lose the soft and comfortable elastic support effect of sofa cushions. Such mattresses and sofa cushions cannot be adjusted in softness, hardness and height, so there is no way to adapt to the special needs of individuals at different times. Even if the sponge, latex cotton, coconut palm and other materials are replaced, the cost is high. In addition, the mask and the edge are made of one body and cannot be disassembled and replaced.

[0014] 1-3: A spring pad connected by elastic interlayers includes a base plate 1, on which a plurality of hard springs 2 are provided, wherein a lifting rod 24 is provided inside the hard spring 2, and a rubber support 25 is provided on the lifting rod 24, and two elastic interlayers 37 are provided above the hard spring 2;

[0015] The elastic barrier 37 includes a barrier 1 42 and a barrier 2 43 provided above the hard spring 2, a soft spring 12 is provided between the barrier 1 42 and the barrier 2 43, the barrier 1 42 includes an elastic spacer 8 and a spacer, the elastic spacer 8 is provided with a plurality of connecting holes 6, a distance limiting rope 7 and a tension spring 9 are provided between two adjacent connecting holes 6, the distance x between two adjacent connecting holes A6 is 38-138mm, and the limited distance y of the distance limiting rope 7 is 2-25mm; the connecting holes 6 A connector A3 is provided inside, and spacers A10 and B11 are provided below and above the elastic spacer net 8 respectively. A slot 4 is provided on both sides of the spacer. The elastic spacer net 8 is fixedly connected to the spacers A10 and B11 through the connector A3. The second partition layer 43 includes a spacer C14 provided above the soft spring 12. A plurality of spacer holes are provided on the spacer C14. An elastic rubber plate 15 is provided above the spacer C14. The spacer C14 and the elastic rubber plate 15 are fixedly connected by a connector B13 provided in the spacer hole.

[0016] Specifically, a surrounding edge is provided around the bottom plate 1, an elastic barrier layer such as an elastic mesh 8 and an elastic rubber plate 15 are fixedly connected to the surrounding edge, a mask is provided above the elastic rubber plate 15, and the mask is connected to the surrounding edge through a hanger. The mask can be removed for cleaning and replacement. The diameter of the connecting hole 6 on the elastic barrier layer is set to 10 mm, and each connecting hole 6 is adjacent to the four connecting holes 6 on the front, rear, left, and right. The distance x between each two adjacent connecting holes 6 is set to 80 mm, and the distance y between each two adjacent connecting holes 6 after being stretched is allowed to increase by 10 mm. The length of the distance limit rope 7 is set to x+y=80+10= 90 mm, the spacer has the function of separating the elastic spacer from the contact with the spring to prevent wear or abnormal noise, and has the function of connecting the two to each other. The spacer A10 also has the function of assisting the hard spring 2 to support the elastic spacer 8. The connection method of the spacer hole 5 can increase the elastic expansion and contraction area of ​​the elastic spacer 8 and improve the elastic expansion and contraction function of the elastic spacer 8. The distance-limiting pull rope 7 set on the elastic spacer 8 can prevent the elastic spacer 8 from being damaged or losing its elastic expansion and contraction function after being stretched excessively. The set tension spring 9 has the function of improving the long-lasting elastic expansion and contraction function of the elastic spacer 8.

This connection method can give full play to the elastic expansion and contraction functions of the elastic spacer 8 and the elastic rubber plate 15. Through the above combination method, the soft spring 12 and the hard spring 12 can be combined in series up and down, and the independent lifting functions of the soft spring 12 and the hard spring 2 can be fully utilized. The hard spring 2 has a hard support effect on the spring pad, and the soft spring 12 can replace the elastic support function of the sponge, and has a soft support effect on the spring pad, which can reduce the use of most sponges and latex cotton.
