An opening-closing member control device includes a motor that opens and closes an opening-closing member of a vehicle, and a control unit configured to stop the motor when determining that a foreign object has been entrapped by the opening-closing member and reverse the motor when a delay time elapses after stopping the motor. When the control unit determines that entrapment has occurred upon operation of a remote operation switch that is separated from the vehicle, the control unit reverses the motor after the delay time that is shorter than when determining that entrapment has occurred upon operation of a vehicle operation switch that is arranged in the vehicle.

A backplate for a door actuator, includes at least two mounting elements, one of the two mounting elements being formed for fastening to a mounting surface, in particular door, casing or wall, and the other mounting element for accommodating the door actuator. The backplate further includes at least one connecting assembly with a bar element mobile disposed at the first mounting element and a thermally activatable trigger element. The bar element is movable from a retaining position to a release position. In the retaining position, the bar element retains the second mounting element and, in the release position, releases the second mounting element. When thermally activated, the trigger element releases a movement of the bar element to the release position and/or, the trigger element moves the bar element to the release position.

A hydraulic door closer capable of reducing oil-pressure therein at high temperature, comprises a housing with an oil chamber, an oil storage cavity, and a piston in the housing of the hydraulic door closer. The oil storage cavity is in communication with the oil chamber; when the oil temperature increases, hydraulic oil in the oil chamber and oil storage cavity generates an increased oil pressure move the piston, whereby volume of the oil storage cavity is enlarged, such that oil from the chamber will flow into the cavity, to reduce the oil pressure of the chamber and cavity. When the oil temperature decreases, the oil pressure in the chamber and cavity is reduced, whereby the storage piston restores its original position, whereby volume of the cavity will be reduced, and the oil in the cavity flows back into the chamber. The pressure in the oil chamber is reduced when the hydraulic oil expands due to increased temperature to prevent failure of the seal and to avoid hydraulic oil leakage.

A door actuator for opening and/or closing a door, comprising includes a fluid housing with an inner compartment, which is filled with fluid, in particular hydraulic oil, a fluid housing opening in the fluid housing for draining the fluid at thermal overload, a thermally activatable valve for opening, which closes the fluid housing opening, and a collecting device which is disposed outside the fluid housing opposite the fluid housing opening, forms a collecting space for the fluid, is open towards the fluid housing opening, and includes at least one drain opening for draining the fluid from the collecting space.

A backplate for a door actuator includes at least one first mounting element and a second mounting element, wherein one of the two mounting elements is formed for fastening to a mounting surface, in particular door, casing or wall, and the other mounting element is formed for receiving the door actuator. The backplate also includes, at least one connecting assembly, which in a retaining position, keeps the two mounting elements together and, in a release position, does not keep the two mounting elements together, and at least one shape memory assembly with a shape memory element made from shape memory material, wherein, upon thermal activation, the shape memory assembly moves the connecting assembly to the release position.

A safe assembly includes a housing having a top wall, a bottom wall, a first side wall, a second side wall, a rear wall and a door. The door having a locking mechanism to releasably lock the door in a closed position. Each of the walls includes an outer panel of steel material defining an exterior of the housing. An inner panel of steel material is spaced from the outer panel and has an exterior face facing the outer panel. The exterior face comprises a highly reflective surface. An insulating material is positioned between and fills a space between the outer and inner panels. A plurality of mating flanges is attached to the walls such that each of the walls includes a mating flange securable to a mating flange on one more adjacently positioned one of the walls to form the completed housing.

A fire protection fastening device for fastening a door actuator, includes a frame with a back side, which is to be oriented to a mounting surface, in particular to a door, casing or wall, wherein a mounting axis is defined vertically to the back side. The frame is formed for arrangement between a door actuator and the mounting surface or is an integral component of the door actuator (102), at least one reaction chamber formed in the frame, wherein the frame delimits the reaction chamber on the entire circumference. The reaction chamber is open on the back side and/or on a front side of the frame opposite the back side. The device further includes a drive element made from thermally intumescent material disposed in the reaction chamber and, when activated, is formed for pushing away the door actuator from the mounting surface.

A sensing edge is made in segments that can be used to determine at which point along the edge an obstruction occurred. Data collected can be used to determine a point in a process that the fault occurred by addressing each segment individually or as a whole. A programmable controller can be operatively coupled to the sensing edge, and can include logic to control the door and/or other equipment using data collected from the sensing edge.
