1. Field of the Invention
The present disclosure relates to a spring mattress structure, especially a spring mattress structure with springs' bottom ends fixed for steady support.
2. Descriptions of the Related Art
The main structure of a pocket spring mattress is based on a plurality of spring sets fixed with outlines for development of a top bed surface and a bottom bed surface, each of which is covered by a cushion layer and wrapped by an external coating.
For a support purpose, a conventional method to fix and assemble springs depends on adhesion or C-shaped rings with hand tools so that each spring's two end surfaces are steadily positioned and sustain top-down axial compressive force.
However, the method to fix and assemble springs according to either adhesion or C-shaped ring, each of which spends much time, is uneconomic. Accordingly, the present disclosure presents a spring mattress structure which relies on spring-loaded locating pieces to rapidly fix and assemble springs without requirement of any hand tool.
Furthermore, the solutions for some issues such as rapid assembly and lowered overall weight not provided in the patent applications U.S. Ser. No. 12/877,275, U.S. Ser. No. 13/028,324 and U.S. Ser. No. 13/534,228 for adjustable softness of a mattress submitted by the applicant on Sep. 8, 2010, are also presented herein.
The present disclosure presents a plurality of shaft levers which constitute a bottom bed surface and are separated by a regular spacing between any two adjacent shaft levers wherein the spacing corresponds to each spring's hollow space and is freely penetrated by each of minor springs hung in the spring's hollow space.
The present disclosure presents spring-loaded locating pieces which are used to quickly fix and assemble springs and shaft levers without requirement of any hand tool.
The present disclosure of a spring mattress structure comprises a mattress body which develops a top bed surface and a bottom bed surface and accommodates: a plurality of springs, each of which develops two opposite stress surfaces along a stretching direction, that is, a first stress surface and a second stress surface, wherein the first stress surface and the second stress surface on which a first placement end and a second placement end are designed get close to or contact the top bed surface and the bottom bed surface that is based on a plurality of shaft levers regularly arranged and separated by a spacing between any two adjacent shaft levers, respectively; a plurality of spring-loaded locating pieces, each of which comprises a locating part with a first elastic fastener and a second elastic fastener extending from both sides for development of a clamping space in between. The locating part of the spring-loaded locating piece is fixed on a shaft lever and allows the first elastic fastener and the second elastic fastener to face the top bed surface; each spring has the second stress surface's first placement end and second placement end placed on two adjacent shaft levers so that the first placement end of one spring and the second placement end of another spring occupy the clamping space developed by the spring-loaded locating piece's first elastic fastener and second elastic fastener and the first elastic fastener's fastening block (the second elastic fastener's fastening block) clamps a spring coil of one spring (another spring) to fix the springs at two adjacent shaft levers and make each spring's hollow space correspond to a spacing between the adjacent shaft levers.
In a preferred embodiment, the locating part of the spring-loaded locating piece develops a positioning space surrounded by at least four borders.
In a preferred embodiment, the positioning space is sealed.
In a preferred embodiment, the locating part has an opening centrally designed at one border, allowing other two borders near the opening to develop elastic arms to which a shaft lever is directly fastened.
In a preferred embodiment, the spring-loaded locating piece comprises the first elastic fastener as well as the second elastic fastener, both of which obliquely extend to each other and have an individual fastening block at top used to clamp a spring coil of one spring.
In a preferred embodiment, the spring-loaded locating piece is provided with a spacer block between the first elastic fastener and the second elastic fastener to separate any two springs without entanglement.
The abovementioned and other detailed technical content, features and effects of a spring mattress structure are presented in preferred embodiments and accompanying drawings as follows.

In each spring 3, the first placement end 321 and the second placement end 322 of the second stress surface 32 are positioned at two adjacent shaft levers 2 so that the first placement end 321 of one spring 3 and the second placement end 322 of another spring 3 occupy the clamping space 44 developed by the first elastic fastener 42 and the second elastic fastener 43 of the spring-loaded locating piece 4 and are separated by the spacer block 413 without entanglement of any two springs 3. Moreover, each spring 3 will be fixed on two adjacent shaft levers 2 and makes its hollow space 33 correspond to the spacing 21 developed by the two adjacent shaft levers 2 when the fastening block 421 of the first elastic fastener 42 and the fastening block 431 of the second elastic fastener 43 clamp the spring coil of one spring 3 and the spring coil of another spring 3, respectively.
