A power strut includes anisotropic damping device that provides different frictional torque on a rotatable member in response to rotation in opposite rotational directions. The anisotropic damping device includes a shell, the rotatable member, and a torsion spring. The shell includes a through hole, and the rotatable member extends through the through hole and is rotatably connected to the shell. The torsion spring is sleeved on the rotatable member and is in interference fit with the rotatable member, and the torsion spring is provided with a first leg fixedly connected to the shell. The rotatable member may include a shaft sleeve fixed to a rotating shaft, with the torsion spring in interference fit with the shaft sleeve.

A device has at least two components which are movable relative to one another. The first component is equipped with a rotary receptacle and wherein the second component is rotatably received on the rotary receptacle. A third component is coupled to the second component. Two connection units which are movable relative to one another and a controllable braking device are included, wherein the braking device is designed as a controllable rotary brake in order to provide controlled damping of a movement of a door device between a closed position and an open position. The first connection unit is formed on the first component, and the second connection unit is pivotably coupled to the third component. The pivot axis is oriented transversely with respect to an axis of rotation of the second component.

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.
