An unlocking device and a door lock are disclosed. The unlocking device includes a signal generating module configured to generate an unlock signal and a control module. The control module comprises a main control unit communicated with the signal generation module, and a drive unit connected with the mechanical lock body. The main control unit is configured to receive the unlocking signal generated by the signal generating module, and control the drive unit to drive the mechanical lock body to unlock according to the unlocking signal received.

Hinged window drive systems and window assemblies incorporating them provide for a combination of powered or motorized operation in addition to manual operation using a hand crank, with the opportunity for a user to switch between motorized operation and manual operation as needed.

The invention relates to a hinge lock consisting of a first hinge part (1) for fastening to the outside of a door and a second hinge part (2) for fastening on the outside of a door frame, wherein the first hinge part (1) has an actuating device, by means of which the first (1) and the second hinge part (2) can be unlocked and locked with one another. The actuating device interacts with a shaft (16), which is suitable for passing through the door. An inner handle (23) is arranged at the end of the shaft (16) facing away from the actuating device, by means of which the first (1) and the second hinge part (2) can be unlocked and locked with one another. The shaft (16) is surrounded by at least one pipe part (18, 18′).

A side-open left-right-door arbitrary-opening structure of a refrigerator comprises four hinge shafts are fixedly connected at left and right sides of a refrigerator body in pairs respectively, left and right sides of upper and lower end faces of a refrigerator door are all provided with an opening neck, each hinge shaft is correspondingly placed in one opening neck, four hinge shaft stoppers are slidably arranged on the upper and lower end faces of the refrigerator door in pairs respectively, one spring is arranged between two hinge shaft stoppers in each pair, tail ends of the hinge shaft stoppers on the upper and lower end faces of the refrigerator door extend into the opening necks at the corresponding sides, and the hinge shafts at the corresponding sides are positioned in the opening necks.

A dampening system (28) that includes an actuation state and/or a door actuation system that includes a single-use pressurized tank (34). The dampening system or the door actuation system may include a damper (30) and a fluid pressure source (e.g., the single-use pressurized tank (34)) that pressurizes the damper to actuate from a first position to a second position. The pressurization allows the damper to actuate another component, such as a vehicle door (26) that is operably coupled to the damper. A user may shift the damper into the actuation state to actuate the vehicle door open during an emergency, such as when a military vehicle is on its side after an explosion knocks over the vehicle and the vehicle door is too heavy for the user to open without assistance.

A toilet seat lifting handle includes a first tubular structure secured about the hinge assembly of a traditionally configured toilet seat. A second tubular structure handle protrudes at a right angle at a first end of the first tubular structure thereby lifting or lowering the toilet seat lid when actuated.

This compartment of a railway vehicle defines an interior volume and comprises: a cover movable between an open position, in which the cover is offset from the interior volume, and a closed position, in which the cover covers the interior volume and at least partially delimits that interior volume, a bar, a central region of the bar extending out of the interior volume, and a hinge defining the path of the cover between open and closed positions.

The cover is rotatable about an axis of the bar between its open and closed positions, the bar forming a pin of the hinge.

An emergency opening device for an aircraft door provided with an opening mechanism includes an actuation device (2, 5) for actuating the opening mechanism, having: a tubular operating member (2) equipped with a second locking end (4) that includes a radial retaining finger (19); flexible compression device (5); a retaining member (9) for the second locking end (4), the retaining member (9) including a hook (28) which has a stop surface, the retaining member (9) being rotatable about the movement axis of the operating member (2); activation device (31) for the actuation device (2, 5), adapted to cause the retaining member (9) to open.

A storage apparatus which allows the secure storage of items within a cavity defined by a base, side walls and a top. Access can be gained to the cavity to allow the removal of introduction of said items by moving a portion of the apparatus between open and closed positions. Locking means are provided to allow the said portion to be retained in a closed position and at least one part of the apparatus is or is provided with at least one sacrificial element such that if a force is applied thereto in an attempt to break the locking means and gain unauthorised access to the cavity, the sacrificial element will break before a sufficient level of force can be applied to break the locking means and hence prevent the said at least one part being used as a means to exert force to break the locking means and gain unauthorised access and theft of items from the said cavity.

A dump gate system for a fluid hopper in a firefighting aircraft. A gate sealably engages a gate opening in the hopper at a closed position. The gate is hingedly connected about the gate opening, and a drive shaft is supported within the hopper. A crank arm is fixed to the drive shaft and is further coupled to the gate by a connecting link. The crank arm and the connecting link define an over-center geometry while the gate is at the closed position, such that weight of the fluid on the gate induces torque on the drive shaft in a gate-closing direction. An electric motor is selectively coupled to rotate the drive shaft in a gate-opening direction to thereby enable control of the fluid flow from the hopper according to an angular position of the drive shaft.
