A flexible spring element is made of a fibre-reinforced plastics composite material, a functional layer made of a fibre-reinforced plastics composite material being located on each of two mutually opposite sides of a central plane of the flexible spring element. At least one matrix material discharge layer extending parallel to the two functional layers and in a longitudinal direction is arranged in at least one longitudinal portion and has at least a fraction of discharge layer fibres which are oriented differently from the longitudinal direction of the flexible spring element. Within at least one curved portion of the flexible spring element a first volume fraction of flexible spring fibres in the functional layers is smaller, preferably smaller by several % than a second volume fraction of flexible spring fibres in the functional layers within the at least one longitudinal portion.

The invention relates to a vibration damper, comprising: a housing, which has a first housing element and a second housing element; a first pin element for connecting to a first plate part; a second pin element for connecting to a second plate part; a first damping insert between the first pin element and the second pin element; a second damping insert between the first pin element and the first housing element; and a third damping insert between the second pin element and the second housing element.

An improved shock isolating mounting comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween. In one arrangement, the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

Collapsible discs move towards or away from each other in embodiments of the disclosed technology by changing the angle of flanges which connect the two discs together. The flanges connect to each respective disc by way of one a fixed connection to one disc and a slidable connection to the other. The flanges slide into portals in the bottom disc and then extend along and into a hollow space therein the bottom disc. The flanges have a tip or multiple tips which is/are wider than a rest of an elongated length thereof which frictionally holds the flanges, and therefore, the discs in places until the discs are rotated causing the flanges to be pulled out from or pushed into the portals. This, in turn, causes the discs to move closer together or become further apart in embodiments of the disclosed technology.

A spring configured to compress, expand, and provide a force is provided that includes a first ring, a second ring, a third ring, a first plurality of rolling elements arranged between the first and second rings, and a second plurality of rolling elements arranged between the first and third rings. When the spring is compressed, the first ring is configured to be elastically deformed in tension in a radially outwardly direction, and the second and third rings are configured to be elastically deformed in compression in a radially inwardly direction.

A device, kit, and method for the treatment of anatomical joint dysfunctions, and more particularly, to a spring hinge comprising: a primary coil spring having a helical structure with a central cavity, wherein the primary coil spring forms a plurality of spirals layered against one another when the primary coil spring is in an unexpanded state; wherein the primary coil spring comprises surfaces that are configured to nest against each other to resist translational or shearing movement between adjoining spiral layers.

A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.
