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 gate hinge for a preferably wooden post which includes an L-shaped rod threaded on one leg with a metal strap rigidly connected to the threaded leg at about one and one half inches from the elbow of the rod on the threaded leg. The metal strap extends six or so inches form each side of the L-shaped rod with two or more holes near each end of the strap. The L-shaped rod is threaded into the post until the metal strap contacts the post. Then each leg of the metal bracket is bent around the post and screws or lag bolts are threaded through the holes and into the post to help secure the hinge to the post and to provide added support for the gate.

The present invention includes a height raising member body mountable to an upper end of a frame disposed above an entrance of a car that moves up and down through an elevator shaft, in which a rail for guiding a car door in an opening and closing direction and a pulley for use in opening and closing drive of the car door are mounted to the frame. The height raising member body characteristically includes: a base part connectable to the frame; and a supporting part capable of supporting the motor at a position upward away from the base, the motor being configured to drive the pulley via a belt.

A door swing control device comprises a bracket affixed to a door, a pivoting element pivotably affixed to the bracket, and a swinging catch mechanism mounted directly or indirectly to the structure. The pivoting element comprises a finger extending therefrom and is engaged with the bracket to limit a range of movement of the pivoting element relative to the bracket. The finger is engageable with the swinging catch mechanism to limit a range of movement of the pivoting element relative to the swinging catch mechanism and thereby selectively limiting a range of movement of the bracket relative to the swinging catch mechanism. When the finger of the pivoting element is engaged with the swinging catch mechanism, the door is held in the first open position. When the finger of the pivoting element is disengaged from the swinging catch mechanism, the door can swing between the first and second open positions.

An opening device, for a cooling device having a door assembly, includes a mounting base, which can be mounted on provided securing units for a door hinge of the cooling device, and a functional unit having an ejection element, which can be moved out in an electrically controlled manner. The mounting base has contacts and the functional unit has counter contacts. The contacts and the counter contacts contact one another when the functional unit is secured on the mounting base in order to supply the functional unit with current.

A counterbalance system for balancing an overhead door installed against a structure of a vehicle or a house, the door having at least one door panel, the system has a longitude pipe with non-circular section cut; a pair of U-brackets having two side walls with one center hole on each side; a pair of torsion spring assemblies received within the pipe, and the inboard end of the assembly being slidingly engaged within the pipe; a pair of connecting shaft, with inboard side connected with the outboard end of each of the spring assemblies; the shaft passing through the center holes of the U-bracket; the outboard end of each shaft being fixed with the side wall on the outboard end of each of the U-brackets; a pair of drums each having a center hole received by the shaft, and each of the drums located between two side walls of the U-bracket.

A system for managing opening and closing a pocket door includes a spindle, an actuator, and brackets. The spindle extends along a longitudinal axis between first and second ends, and is configured to be coupled to the pocket door. The actuator is coupled to the spindle and is configured to cause the spindle to move axially along the longitudinal axis. The brackets are connected to the spindle at each end and are constrained from longitudinal motion relative to the spindle. The brackets are configured to affix the spindle to the pocket door. A bushing system couples each bracket to the spindle and is configured to dampen impact between the spindle and the brackets. For example, the bushing system may include lobed elements, made of a rubber material, that engage each other to transmit azimuthal forces. In some embodiments, another actuator is included to improve cycle like and redundancy.

A refrigerator includes at least one hinge assembly configured to hinge a door to a cabinet. The at least one hinge assembly includes a mounting block coupled to, and that extends at least partially along, the door. A hinge bracket is coupled to the cabinet. The hinge bracket is coupled to a top panel of the cabinet and includes an upward extending flange that spans a width of the cabinet and that is coplanar with a front panel of the door. A hinge pin is disposed between the mounting block and the hinge bracket and is coupled thereto such that the entirety of the hinge pin is external to the door and is positioned between the door and the hinge bracket.

Provided is an opening/closing body opening/closing device capable of effectively preventing water such as rainwater flowing down from an opening/closing body carried by a carrier plate from adhering to a guide rail. The opening/closing body opening/closing device includes a carrier plate that carries an opening/closing body, and a guide rail that guides movement of the carrier plate in a lifting and lowering direction of the opening/closing body. The carrier plate includes, at an upper end portion, a water holding section that holds water reaching the upper end portion of the carrier plate from above. The water holding section includes a water receiving section that faces upward and receives the reaching water, and an outflow preventing section provided with a preventing surface that faces the water receiving section side and prevents the water from flowing out to the guide rail.

A vehicle door that includes at least a door skin, a carrier component fixed the door skin for separating a wet space from a dry space on the vehicle door, wherein the carrier component has a wet-space side facing the wet space and a dry-space side facing the dry space, a speaker arranged on the carrier component, and a resonance body component connected the carrier component for forming a resonance space for the speaker on the wet-space side of the carrier component. The resonance body component, which together with the carrier component forms the resonance space for the speaker, forms a rail carrier surface on which at least one guide rail is provided for a window regulator of the vehicle door.
