Disclosed are an electronic lock (100) and a light colour control method for the electronic lock (100). The electronic lock (100) comprises a lock body (1), a lock hook (2), at least two shifting beads (3), a lock shifter (4), a motor (5), a motor actuator (6), and an elastic member (7), wherein the shifting beads (3), the lock shifter (4), the motor (5) and the motor actuator (6) are mounted in the lock body (1), the motor actuator (6) is mounted on the motor (5) and interlinked with the lock shifter (4), the lock hook (2) is mounted on the lock body (1) and is able to move with respect to the lock body (1), the shifting beads (3) cooperate with the lock hook (2) such that the electronic lock (100) is transformable between a locked state and an unlocked state, and the elastic member (7) is mounted in the lock body (1) and exerts an acting force on the shifting beads (3) in opposite directions towards the lock hook (2) so that the shifting beads (3) do not exert any acting force on the lock shifter (4) during a progress of unlocking and locking. In the electronic lock (100), the shifting beads (3) do not exert any acting three on the motor (5) during a progress of unlocking and locking, and the motor (5) is in an unloaded state, thereby lowering demand for power supply and for the voltage and power of the motor (5), reducing energy loss and prolonging the service life of the electronic lock.

A hold-open arrester arrangement has a low power consumption, and therefore a battery lifetime is long in the embodiments of the invention utilizing the battery. The hold-open arrester arrangement has a hold-open arrester arrangement having a hold-open function to hold a door open. The arrangement has also an electric release arrangement. The release arrangement is arranged to release the hold-open function in a fire alarm situation. The hold-open arrester arrangement comprises a sliding block and an arrester unit. The sliding block is connectable with a slide rail in a sliding manner and also pivotable connectable to an arm of a door closer. The arrester unit is connectable to the slide rail and has a body, said electric release arrangement, and said hold-open function with the sliding block.

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 hinge arrangement having a first hinge part and having a second hinge part, which are connected to one another such that they can pivot, a first hinge pin being formed on the first hinge part, on which a first hinge sleeve is pivotably mounted, which forms a first sliding bearing with the first hinge pin, a dimensionally stable support part being connected to the first hinge sleeve. A first axial protrusion is formed on a first axial end face of the first hinge pin, which engages in an arcuate first groove of the first hinge sleeve, wherein a circumferential first side wall of the first groove together with the first axial end face and an inner side of an end cover fixed at the end of the first hinge sleeve delimits a working space which is filled with a damping fluid for damping a relative movement of the first axial protrusion with respect to the first groove.

Provided is a damper device capable of increasing torque of a coil spring without increasing an outer diameter of a case. The damper device includes the case (2), a shaft (3) that is relatively rotatable with respect to the case (2), fluid filled in a damper chamber (5) formed between the case (2) and the shaft (3), a bearing member (4) that forms a partition wall (5a) that closes one end of the damper chamber (5) in an axial direction and is separate from the shaft (3), and a coil spring (9) having one end connected to a side of the case (2) and the other end connected to the shaft (3) or the bearing member (4) to apply torque to the shaft (3) with respect to the case (2). The bearing member (4) is arranged between a winding portion (9a) of the coil spring (9) and the damper chamber.

It is described herein a venting apparatus for an opening in a roof. The venting apparatus for an opening in a roof may comprise a structural frame, an adapter, a mount, a hinge, and a latch. The adapter may comprise a frame adapter section, a lip extending inwardly from a portion of the frame adapter section inner surface, and a protrusion extending upwardly from the lip. The frame adapter section may be configured to fit around an outer surface of the structural frame while the mount may be configured to fit around an outer surface of the protrusion. The latch may be configured to receive a signal from a device when the device detects the presence of smoke within the building to cause the latch to change from a latch closed position to a latch opened position.

A structure for assisting with opening and closing of a lower door includes a lower door having an upper end configured to be rotated open with respect to a bottom surface of a vehicle body, and a rotary unit configured to be fixed to the bottom surface of the vehicle body and configured to rotate in opposite directions to assist with opening and closing of the lower door.

An emergency door closing device that can be installed upon existing doors and hinges to automatically close doors in the response to smoke and fire. The improvements incorporated therein include a hinge cam pivot member that attaches to an existing hinge member of a door and produces a moment force about the existing hinge member allowing a reduced force necessary to pivot the door into a closed position. Further, a novel spring, cam, and lever system is incorporated to activate the moment force to close the door.
