Abstract: A spring module for furniture includes a conical spring and a plurality of flexible straps. Each flexible strap has a strap-like main body and a first hook at the first end of the main body and a second hook at the second end of the main body. The first hook is configured to be removably hooked on a larger diameter end of the conical spring, and the second hook is configured to be removably hooked on a smaller diameter end of the conical spring. When the first hook and the second hook are hooked on the conical spring, the flexible straps are positioned outside the conical spring.

The plate body, when in use, is rotatably supported between two front leg tubes of the foldable ladder. The front end cap and the rear end cap are respectively connected to the plate body from a front-and-rear direction. A bottom of the plate body comprises a plurality of protruding strips. The plurality of protruding strips are hollow. The plurality of protruding strips are arranged at intervals. The front end cap comprises a plurality of first inserting pins configured to correspond to the plurality of protruding strips, and the rear end cap comprises a plurality of second inserting pins configured to correspond to the plurality of protruding strips. The plurality of first inserting pins and the plurality of second inserting pins are respectively inserted into the plurality of protruding strips.

Abstract: A structure of a spring module group for installing independent springs, the spring module group is configured to be assembled to form a spring mattress, the spring module group includes a connecting base and a plurality of elastic modules assembled on the connecting base, the connecting base includes a plurality of through holes corresponding to the plurality of elastic modules, the connecting base includes one or more buckling grooves configured to limit the plurality of elastic modules from being separated from the connecting base, and the one or more buckling grooves are configured to be releasably buckled to the plurality of elastic modules.

Abstract: A spring assembly for a cushion includes multiple rows of independent flexible material-wrapped spring module groups. Adjacent rows of the multiple rows of the independent flexible material-wrapped spring module groups are detachably connected by a connecting member, and independent springs in the adjacent rows of the multiple rows of the independent flexible material-wrapped spring module groups are springs of a same type or springs of different types. The adjacent rows of the multiple rows of the independent flexible material-wrapped spring module groups have endpoints arranged in an aligned arrangement or in a staggered arrangement. At least one disconnection area is disposed at a joint side of two adjacent springs in the independent flexible material-wrapped spring module groups, and a preset gap is formed between the adjacent rows of the multiple rows of the independent flexible material-wrapped spring module groups connected by the connecting member.

Abstract: One or more springs having at least one positioning ring and an elastic mattress are provided. Each of the one or more springs comprises a spring body having a spiral shape formed by winding, two ends of the spring body are wound to form two end surface rings, the spring body comprises the at least one positioning ring, the at least one positioning ring is a winding ring of the spring body, the at least one positioning ring is substantially parallel to the two end surface rings or is substantially perpendicular to a direction of an elastic force of the spring body, and the at least one positioning ring is at least spaced apart from a stressing end for ¼ of a length of the one or more springs.

Abstract: A spring module for a furniture cushion includes a conical spring and a double-layer flexible sleeve. The double layer flexible sleeve has a frustoconical first outer layer having a first closed top end, a first open bottom end, and a first outwardly extending flange at the first open bottom end. A frustoconical second inner layer inside the frustoconical first outer layer has a second closed top end, an open second bottom end, and a second outwardly extending flange at the open second bottom end of the frustoconical second inner layer. The conical spring is between the first outer layer and the second inner layer. The spring module may be attached to a base having locking structures for locking adjacent spring modules together.

Abstract: A spring module for a spring cushion for furniture. includes a base (20), an end cap (30) and a spring (10) arranged between the base and the end cap. The end cap has a flexible connection portion (33) and is configured to be detachably fixed to the base (20). The flexible connection portion (33) is located radially inside the spring (10). The spring module provides improved stability. The spring cushion has a simple structure and is easy to assemble and disassemble.

Abstract: A composite board has a vacuum molded surface plate (12) and a bottom plate (13). Edges of the surface plate (12) and the bottom plate (13) are fixed into one piece by thermoplastic fixation, and a top wall of each supporting protrusion (135) and a body of the surface plate (12) are fixed into one piece by thermoplastic fixation. The composite board is formed by superimposing at least two layers of boards. A method for manufacturing the composite board provides process guidance for manufacturing the composite board.

Abstract: An elastic cushion and an elastic module unit for furniture. The elastic module unit configured for assembling into an elastic cushion, the elastic module unit comprising a fixed base plate and a plurality of elastic modules disposed on the fixed base plate; wherein a side edge of the fixed base plate is provided with a second connecting structure configured to releasably connect an edge fastening device which releasably connects a pad layer of the elastic cushion with the second connecting structure such that the elastic cushion can be formed as an elastic cushion with fully opened sides by means of the edge fastening device, thereby improving the comfort of the elastic cushion, improving the ventilation of the elastic cushion, meanwhile facilitating assembling and disassembling of the elastic cushion, and effectively reducing the storage space of the elastic cushion.
