A seat member has a seat portion, a receiving surface of which comes into contact with a bearing surface of an end turn portion, a mounting shaft portion protruded from the receiving surface of the seat portion, and an enlarged diameter portion formed at the front end of the mounting shaft portion for guiding press-fitting, in a cross section along an axial direction of a coil spring, an outer diameter of the enlarged diameter portion is set larger than an inner diameter of the end turn portion and an axial length of the enlarged diameter portion is set so that at least a maximum diagonal length of the seat member is larger than an inter-element wire distance.

A method for installing a wrap spring includes providing a first sleeve with a first longitudinal axis extending in an axial direction and a lateral surface, and the wrap spring designed to frictionally abut the lateral surface. The wrap spring includes a nominal diameter and a central axis. The method includes applying the wrap spring in a relaxed state to the lateral surface at an angle α between the central axis and the first longitudinal axis, elastically twisting the wrap spring to change the nominal diameter while the wrap spring contacts the lateral surface, reducing the angle α, threading the wrap spring onto the first sleeve, and relaxing the wrap spring to establish frictional contact with the lateral surface.

A furniture fitting includes a mounting device for releasably fastening the furniture fitting to one of two furniture parts, an actuating device which can be connected to the other of the two furniture parts and which is mounted so as to be movable relative to the mounting device, an energy accumulator which has a spring element formed from a wire, an the spring element is designed as a coil spring, and a force transmission mechanism by which energy which can be deposited in the energy accumulator can be transmitted to the actuating device. The wire has, in a cross-section normal to a longitudinal axis of the at least one wire, an outer contour which deviates from a circular shape.

A spring apparatus that has a section that is predominantly horizontal and a section of the spring that is predominantly vertical. The multiple spring assembly design allows for increased surface area, fluid flow, and improved heat transfer properties. The unique design allows the spring to fit in tight spaces and decreases issues when manufacturing complex spring designs and allows for efficient heat and fluid flow inside a tubular.

A coil spring includes a wire rod and an elastic coat provided on the wire rod. The coil spring includes a coil section including a plurality of coil portions. The wire rod includes a round cross-sectional portion, a cross-section varying portion, and a rectangular cross-sectional portion along the longitudinal direction of the wire rod. The cross section of the rectangular cross-sectional portion is substantially square and has a first plane and a second plane. The first plane and the second plane oppose each other in the coil section. The elastic coat is provided on at least one of the first plane and the second plane. The elastic coat is continuous from the round cross-sectional portion to the cross-sectional variation portion and the rectangular cross-sectional portion.

A wire material for a canted coil spring includes a core wire composed of a steel having a pearlite structure, a copper plating layer covering the outer peripheral surface of the core wire, the copper plating layer being composed of copper or a copper alloy, and a hard layer disposed adjacent to the outer periphery of the copper plating layer, the hard layer having a higher hardness than the copper plating layer. The steel constituting the core wire contains 0.5% or more by mass and 1.0% or less by mass carbon, 0.1% or more by mass and 2.5% or less by mass silicon, and 0.3% or more by mass and 0.9% or less by mass manganese, the balance being iron and unavoidable impurities.

Helical compression spring for use in an actuator for opening and closing a door or a tailgate of a car has an outer diameter between 15 and 50 mm and comprises a helically coiled steel wire. The steel wire has a non-circular cross-section with an equivalent diameter d (in mm) of the steel wire is between 1 mm and 12 mm. The cross-section may have at least two opposing parallel sides. The cross-section further has rounded edges, wherein the rounded edges have a radius of curvature ranging from 0.10 mm to 5.0 mm. The microstructure of the steel wire in the helical compression spring is cold deformed pearlite. In comparison with helical compression springs with round cross-sections, the non-round helical compression springs may occupy less space or reach higher breaking loads within the same space.
