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.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

A control apparatus controlling an opening and closing member for a vehicle includes a drive control unit operating an opening and closing member of the vehicle by a motor serving as a drive source, and a catch detection unit detecting a catch of a foreign object caught by the opening and closing member in response to a current value of the motor. The drive control unit includes a motor control signal output unit outputting a motor control signal for supplying a drive power to the motor, and an advance-angle value setting unit setting an advance-angle value for advancing a phase of the motor control signal. The advance-angle value setting unit includes an advance-angle value increase prohibition unit prohibiting increase setting of the advance-angle value in a case where the current value of the motor reaches an advance-angle value increase prohibition current value.

A device and method for automatically closing a tailgate of a motor vehicle having a body and a tailgate closing device, is described. The tailgate closing device comprises first and second closing elements. A suspension strut is situated on a first side of the tailgate and a power strut is situated on a second side of the tailgate opposite the first side. The suspension strut and the power strut are both connected to the tailgate and to the body. The first closing element is situated on the tailgate and the second closing element is situated on the body. The first and second closing elements are designed to engage into each other during the closing of the tailgate to effectuate the closure of the tailgate. The torque acting via the power strut onto the tailgate is reduced during the closing of the tailgate when the distance between the first and second closing elements is less than a threshold value.

A retention assembly may comprise a motor assembly and a self-locking worm drive coupled thereto. A cam may be fixed to a worm gear of the worm drive. The retention assembly may further comprise an actuation shaft including a follower. The actuation shaft may be displaceable over a displacement range via rotation of the cam. The retention assembly may further comprise a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly may further comprise a housing cam included as part of the retention assembly housing and against which the securement member follower may be biased. The securement member may be in an open state when the actuation shaft is in a first position. The securement member may swing outward to a retaining position as the actuation shaft is moved to a second position.

A lifting system for door leaves of furniture that swing about at least one horizontal axis between a closed position and a raised open position, the lifting system comprising a supporting body which can be connected to a fixed portion of the item of furniture, a system of articulated levers which are connected to the supporting body and to a door leaf of the item of furniture, the system of levers comprising a first lever which has an end connected rotatably to the supporting body and a second lever, the first lever and the second lever being mutually articulated at the respective other ends, and elastic actuation means, which are functionally connected to the system of articulated levers in order to generate a rotation torque for the system of levers, and further comprising elastic initial opening means.

A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; one or more biasing components to bias the hinge toward a closed position; and a dampener to slow movement of the first and second leaf assemblies to the closed position, a first portion of the dampener is located within the first insert component and a second portion is configured to at least partially retract within the first insert component when coming into contact with the second leaf assembly during movement, a second portion of the dampener extends and retracts along an axis coplanar with the first panel.

An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

A gate opening apparatus includes an external housing, a main chassis, a motor device, a driving rotor, a plurality of guiding rollers, a transmission chain connecting the driving rotor, the guiding rollers and a door gate, and a gate actuating arrangement. The gate actuating arrangement includes a clutching device supported on the main chassis and connected to the motor device, a limit switch assembly coupled to the clutching device, and a control module. The gate opening apparatus is arranged to operate between a power mode and a manual mode. In the power mode, the clutching device is engaged with the driving rotor for driving a movement thereof by the motor device so as to selectively open and close the door gate. In the manual mode, the clutching device is disengaged from the driving rotor so that the driving rotor is adapted for being rotated manually.
