Abstract:
Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.

Disclosed is a spring formed from a synthetic resin into one body, including: a plurality of annular members arranged in such a manner as to be coaxial with each other and spaced in parallel to each other; and elastic linkage members for linking the annular members to each other at a plurality of points. In the spring, each of the elastic linkage members is arranged along a virtual cylindrical face formed by the annular members and formed into a lying U-shape curved in the peripheral direction of the annular members; radii of adjacent ones of the annular members are different from each other; and one end portion and the other end portion of each of the elastic linkage members, which portions are respectively linked to the adjacent ones of the annular members, are not overlapped to each other in the axial direction. These springs are locked integrally with a pair of upper and lower network plane members, which members include over the surfaces thereof locking members for locking upper and lower ends of the springs respectively, in such a manner as to be held therebetween, to form a spring assembly for a mattress.
Abstract:
A device for connecting springs together to define a support surface includes four arms each which extend in an outward radial direction from a center of the connecting device, the length of each arm defined by two sides extending in spaced relation to one another. Each arm includes a stiffening portion extending in a widthwise direction between the sides of the arm and extending from an end thereof towards the center of the connecting device only partially along the length of the arm. The straight sides of each arm have identical height dimensions and the stiffening portion has a lesser height than the height of the sides. The sides and the stiffening porting of each arm together define a planar surface of the arm and a finger portion extends from the end of the arm to define with the planar surface a U-shaped recess for gripping a top coil of a coil spring. The four arms define an X-shaped connecting device and further define an X-shaped opening extending through the connecting device which is approximately one-half the size of the X-shaped connecting device. Alternatively, the four arms define a circular opening extending through the connecting device.

Abstract:
A bedding or furniture spring product comprising a plurality of coil springs arranged in linear rows and columns. Each of the coil springs is preloaded by an endless strip of fabric, the strip of fabric encircling the exterior of one of the coil springs. The interior surface of the strip of fabric may be coated with a non-slip material so as to prevent the strip from falling or moving off the coil spring. Alternatively, the coil spring itself may be coated with a non-slip material. The strip of fabric leaves a portion of the end turns of the coil springs uncovered enabling the coil springs to be secured to a wire grid as for example by being wrapped around or clipped or laced to wires of the grid assembly. Alternatively, traditional hand 8-way tie may be used to connect the precompressed coil springs together and to a frame.

An innerspring structure for a mattress comprises a plurality of outer coils extending generally parallel with each other to collectively form top and bottom face surfaces of the innerspring structure. One or more of the outer coils has an inner coil of preferably similar shape positioned generally coaxially with the respective outer coil. In one embodiment, a helical lacing wire wraps together adjacent end turns of the inner and outer coaxially aligned coils to form reinforced coil units in an area of the innerspring structure to increase the firmness of an area of the mattress utilizing the invention. Helical lacing wire connects the coils of the structure together and connects the end turns of peripheral coils to a border wire surrounding the periphery of the structures at the top and bottom face surfaces. In another embodiment of the invention, the structure comprises a row of inner coils and a row of outer coils, each formed from a single continuous piece of wire such that adjacent coils of the row are interconnected by interconnection segments. The rows of coils are positioned together so that the inner coils are coaxial with the outer coils to form reinforced coil unit.

A bedding product comprising a collapsible spring assembly, a pad covering the spring assembly and a fabric covering encasing the padded spring assembly. The spring assembly comprises a plurality of collapsible spring modules connected to a plurality of spaced parallel connecting rods and locking means to hold the assembly in an expanded condition and prevent its collapse. The parallel connecting rods are located between border rods in the top and bottom planes of the assembly. Each of the spring modules comprises four individual wires joined together with helical lacing wire wrapped around a center section of each of the wires. The center sections of the wires define an axis about which each of the wires are capable of rotational movement. Upon the collapse of the assembly, each of the spring modules collapses rotating around the axis of the module. The assembly is held in an expanded condition by a plurality of locking rods, pieces of plastic mesh or other locking means.

An innerspring assembly, such as for use in a mattress, comprises a plurality of coil springs defining upper and lower terminal convolutions and body portions therebetween. Adjacent coil springs are attached together at the body portions thereof with the terminal convolutions being unattached to one another, so that the terminal convolution can move independently of one another.
Abstract:
In the production of a pocket spring assembly, two layers of fabric are secured together along multiple parallel seam zones so as to form a quilt defining a plurality of parallel fabric tubes, the tubes so formed are supported on guides extending longitudinally through the tubes, portions of the quilt are repeatedly drawn from the guides at their one ends and folds formed in each layer of fabric in the drawn off portion are secured to form pockets from the drawn off portions of the quilt, and precompressed coil springs are passed through the guides and released into the pockets between each drawing of the quilt, with their axes perpendicular to both the axes of the fabric tubes and the direction of advancement of the quilt, so that secured folds in the fabric of the tubes in front of and behind the released springs retain them in the pockets. Spaced longitudinal slits are formed in the seam zones, the slits permitting the fabric to envelope the tubes.
Abstract:
A damping body for damping periodically alternating loads uses a shape-memory alloy material to govern the damping. The damping body is sintered from metal grains or is laminated from a plurality of perforated sheet-metal layers. The individual sheet-metal layers are orientated transversely or parallel to the loading direction and are connected to one another over the full surface area. A combination formed from a multiplicity of round pins orientated parallel to the loading direction and having enclosed gussets can also be used as a damping body. A certain hollow-space portion inside the damping body can also be created by drilling, slitting or grooving. The proportion of the open pore or bore volume of the damping body to the total volume is at least 5%, preferably about 15 to 40%. On account of the hollow spaces integrated in the damping body, multiaxial stress states impairing the damping behavior can be effectively avoided or at any rate reduced even in an unfavorably flat or wide configuration of the damping body.
