A rotation damper for damping movement of a component includes a transmission element couplable to the component such that the transmission element is rotated during movement of the component, and including a rotatingly mounted rotor and also braking device which brakes a rotational movement of the rotor. A coupler couples the transmission element and the rotor for conjoint rotation in a first direction of rotation and decouples the same in a second, opposite direction of rotation. The coupler includes a support element on with an engagement element that is pivotable between an engagement position and a release position. The engagement element has at least one coupling portion, and the transmission element has at least one coupling portion which is in engagement with the at least one coupling portion of the engagement element. The coupling portions are formed in a complementary manner with respect to each other.

A press on shoe cover includes a bottom layer and at least one bistable spring band. The bottom layer is sized to cover at least a bottom of a shoe. The at least one bistable spring band is attached to the bottom layer. The at least one bistable spring band having a stable planar position and a bias coiling position. The stable planar position is configured to hold the bottom layer flat. The bias coiling position is configured to wrap the bottom layer around at least the bottom of the shoe. When the shoe cover lays flat on a surface and the bottom of the shoe is pressed down on the shoe cover, the bistable spring band is configured to move to the bias coiling position thereby wrapping the bottom layer around at least the bottom of the shoe and securing the shoe cover on the bottom of the shoe.

Composite suspension components are disclosed. The components are made from resin containing elongated fibers (8). The arms of the suspension components may receive reinforcement (40) using different devices and methods. A composite torque rod also incorporates a tunable compliance feature.

An article includes a body having at least a holding or resting surface, and a plurality of spaced-apart fine pillars made of a resilient and deformable plastic material and projected from the holding or resting surface of the body. Each of the spaced-apart fine pillars includes a body portion with a bore defining a longitudinal axis, a base end and a free end. The base end of the fine pillar is integrally connected with the holding or resting surface the body. The body portion of the fine pillar extends from the base end along the longitudinal axis to the free end in a predetermined height. The fine pillars can be able to deform elastically when subjected to even a minimum pressure to provide the anti-skidding, shock-absorbing and breathable capacities.

A friction disc producible at low cost is disclosed. A support plate includes a first engaging protrusion, a through-hole, a second engaging protrusion, and a recess. The first engaging protrusion protrudes from a first lateral surface of the support plate to a first side in an axial direction. The through-hole extends inside the first engaging protrusion in the axial direction. The second engaging protrusion protrudes from a second lateral surface of the support plate to a second side in the axial direction. The recess overlaps with the second engaging protrusion as seen in the axial direction. The recess is recessed on the first lateral surface to the second side in the axial direction. A first friction material includes a first engaging recess engaged with the first engaging protrusion. A second friction material includes a second engaging recess engaged with the second engaging protrusion.

This disclosure is directed to an anti-moment machine and a moment resisting device thereof, device. The anti-moment machine has a machine body and at least one pair of moment resisting device. The moment resisting devices are respectively arranged on two sides of the machine body oppositely. Each moment resisting device has a base, a bracket, an elastic arm and a damper. elastic arm is respectively connected to one side of the base and a bottom of the bracket, and an obtuse angle is defined between the base and the bracket. The damper is connected between the base and the bracket. The machine body is applied preload moments and preload lateral forces from the moment resisting device respectively to balance the moment in the machine body and reduce vibrations of the machine body.
