Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

A complex spring unit (10) comprises at least a first spring portion (12) and a second spring portion (14), which first and second spring portions are integrally formed, wherein the first spring portion is arranged in use to be placed under compression, and the second spring portion is arranged in use to be placed under tension, during compression of the complex spring unit.

A high tension coil spring structure for a bed mattress includes spring bodies and exposed wiring portions which absorb an external load. Diameter-increasing portions (A) are formed on at least one of upper and/or lower end wiring portions (14, 14) of body wiring portions (12), and provide spaces in which upper and/or lower exposure start wiring portions (16-5, 16-5) move upward and downward. Rigid support ends (18) are formed on at least one of the body wiring portions (12) and upper and lower exposed wiring portions (16, 16), and absorb a compressive load. The diameter-increasing portions and the rigid ends of the coil spring structure fundamentally prevent noise caused by friction between the exposed wiring portions and surrounding wiring portions when the exposed wiring portions are compressed and significantly increase the elasticity of the exposed wiring portions.

The invention relates to the field of beds or seats. In particular, the invention relates to a flexible element (10) stiffness that is adjustable stiffness along a compression axis (Z), the element including a compression spring (50). In order to enable the stiffness of the stiffness element (10) to be adjusted, it further comprises both a mechanism (150) coupled to the compression spring (50) so as to be actuated by compression of the compression spring (50) along the compression axis (Z) to move in a direction other than the direction of the compression axis (Z), and also an adjustment device for selectively restricting or releasing the movement of the mechanism (150). The invention also provides a unit (200) comprising a plurality of such flexible elements (10), and a method of adjusting the stiffness of the flexible element (10).

Cushions include a chassis core having a rigid or semi-rigid base sheet; and a plurality of paired flat springs coupled to the rigid or semi-rigid base sheet, wherein each paired flat spring comprises a lower flat spring including a first terminal end, a second terminal end, and a flexible arcuate member extending from the first terminal end to the second terminal end, and an upper flat spring including a first terminal end, a second terminal end, and a flexible arcuate member extending from the first terminal end to the second terminal end, wherein the first and second terminal ends of the upper flat spring are fixedly attached to respective first and second terminal ends of the lower flat spring such that the upper flat spring is inverted relative to the lower flat spring. Also disclosed are processes for manufacturing the core chassis.

An elastic module unit for a pad or furniture may include a fixed bottom plate and a plurality of elastic modules disposed on the fixed bottom plate, the fixed bottom plate including splicing sides arranged opposite to each other and end sides arranged opposite to each other. Each of the end sides includes a plurality of connectors having a rotary detent member and/or an engagement member. The rotary detent member is configured to swing about a pivot axis so that it releasably engages an engagement member of an adjacent elastic module unit. The engagement member is configured to releasably engage a rotary engagement member of an adjacent elastic module unit.

An apparatus for assembling a bedding foundation having spring modules and a frame includes a support configured to receive the frame, a bridge disposed over the support, and staplers movably coupled to the bridge and positioned over the support, each stapler configured to staple a spring module to the frame. The apparatus also includes cameras coupled to the bridge and positioned over the support. Each stapler is operatively associated with one of the cameras and each camera is positioned to provide a field of view toward the support. The apparatus also includes a driver configured to move the frame relative to the support and a controller in communication with the cameras and the driver, the controller configured to receive vision guidance signals from one of the cameras to direct movement of the driver and of the stapler operatively associated with the one of the cameras.

The present invention provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the conical spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present invention further relates to a spring cushion having the spring module.
