Abstract: The invention relates to a wrap spring for blocking an unwanted rotational movement of a rotary element. The invention further relates to an adjusting device for adjusting the wear of brake pads of a disk brake. An adjusting device comprises a guide sleeve in which a wrap spring is arranged, a grooved ring which encompasses the guide sleeve, wherein the grooved ring is coupled to a closure cap via a torsion spring, and an opening ring encompassing the grooved ring. The invention further relates to a disk brake for a vehicle, in particular for a utility vehicle, wherein the disk brake comprises an adjusting device with a wrap spring.

Abstract: The invention relates to an upholstery spring device (1), especially for upholstery cushions, mattresses, or similar, comprising a plurality of upholstery spring elements (2). The aim of the invention is to create an upholstery spring device (1) which can be used with a great degree of flexibility while being simple and inexpensive to produce. Said aim is achieved by an upholstery spring device (1) comprising a plurality of adjacent upholstery spring elements (2) which are joined to each other by means of a flexible connecting device (5, 120) so as to form a joint unit.

Abstract: A suspension assembly for use in a chair or sofa seat having a top strap secured to a bottom strap forming a pocket into which a rigid frame is inserted. In a first preferred embodiment, the rigid frame biases the straps both together and longitudinally towards the pocket ends. In a second preferred embodiment, the rigid frame biases the straps both open and longitudinally towards the pocket ends. Springs are inserted into the pocket to continually bias the pocket open. The opposing biasing forces of the frame and the springs form a pretensioned suspension assembly that may be installed in seating applications without further stretching of the assembly during installation in a chair or sofa frame.

Abstract: Described is a spring core for a mattress, consisting of a multiplicity of identically shaped spiral springs with in each case two end rings lying diametrically opposite each other, which change to a spring coil part arranged centered between them, whereby the end rings are shaped approximately circular and consist essentially of two assembly legs, one transition leg and one additional leg and are opened on one side, whereby the leg lying opposite the respective open side of the upper or lower end ring is bent radially outward with respect to the longitudinal axis of the spring.

Abstract: A spring seating support system which includes an upper support frame that includes rigid wire grids located between adjacent rows of coil springs. The rigid wire grids are flexibly connected to the top loop of the coil springs located in adjacent rows, and are comprised of latitudinal perimeter wires welded to longitudinal support wires. Latitudinal interior wires welded to the longitudinal support wires may be added for additional strength where the distance between rows of coil springs requires such support.

Abstract: A drop-in spring assembly unit and method of manufacture of furniture. The assembly unit includes a plurality of spring elements coupled together by unique individual grid inserts, a wire base that may be customized to customer specifications and a border wire surrounding the top perimeter of the unit. The grid inserts are assembled prior to assembly of the drop-in unit and are coupled to spring elements by cushion clips.

Abstract: A spring assembly for mattresses, innersprings, and the like. The assembly comprises rows of coils, each row comprising a continuous length of wire formed into a plurality of coils interconnected by Z-shaped wire segments alternately disposed at the top and bottom of the coils. Adjacent rows of coils are connected by a helical wire wound through overlapping Z-shaped wire segments. The overlapping connected segments on opposite sides of each coil are located in a common diametrical plane of the coil so that complete compression of the coil does not result in the coil being pulled laterally, twisted and distorted.

Abstract: A spring clip for interconnecting coil springs with tie wires to maintain the coil springs in spaced lengthwise and crosswise rows in the spring assembly, in which the clip member spans the adjacent chords of the terminal coils of the coil springs and receives the adjacent tie wires and the adjacent portions of the terminal coils of the coil springs in respective inwardly and outwardly facing channels with a tongue for leading the clip member into the assembled relation.
