Abstract:
A damper assembly includes a fixed rack gear, a rotary gear damper having a gear engaged with the rack gear, and a tether movable with the damper along the rack gear and connected to the movable object to be controlled by the damper. A biasing element normally urges the damper away from anti-rotation locking members.
Abstract:
A hinge includes a housing. A sliding cam slideably received in the housing defines concave portions and an axial hole. A rotatable cam mating with the sliding cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines an accommodating hole. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fixed at an end of the housing. A shaft received in the housing runs through the axial hole and the spring. An end of the shaft is received in the accommodating hole, and the other end of the shaft passes through the end of the housing. A first stop has a bottom surface whose part extends downward to form a blocking portion, and the rest part of the bottom surface is defined as a revolving platform. A second stop engaging with the rotatable cam has a top surface protruding upward to form a pushing block rotatablely disposed on the revolving platform. And a cap rotatablely receives the first stop and the second stop.
Abstract:
An active break release device driven by a second motor and externally attached to the door controller, which is used for the triggering of automatic brake releasing to close the safety door in unexpected electricity failure condition, in which the door controller have a housing for receiving a first motor, the driving torque of which is transferred through a rotary shaft to a reel for winding the door; a braking device is provided at the outside of said rotary shaft, which includes a braking portion normally located at a brake activating position, and located at a brake releasing position when the first motor is energized, characterized in that the active break release device comprises: at least a brake releasing rod, one end of which activates the braking portion to release braking by leverage action force, while the other end of which extending to the outside of the door controller; at least a second motor, provided externally at the door controller and moved together with the other end of the brake releasing rod; a circuit having a backup power source used to temporarily supply electricity to the second motor in case of unexpected electricity failure condition, so that the braking portion being driven to release braking. In this manner, the braking can be automatically released at the first instant of electricity failure so as to close the safety door.
Abstract:
A latching rack damper assembly configured to dampen movement between two structures includes a rack and a damper housing. The rack includes a toothed track and an integrally formed first latching member. The damper housing is movably secured to the rack and includes a second latching member configured to securely latch to the first latching member.
Abstract:
The invention relates to an actuating device for moving a flap of a piece of furniture, comprising, at least one actuating arm for moving said flap, a base member on which said actuating arm is pivotally arranged, a spring device being able to act upon said actuating arm, wherein an assembly securing device for the vacant actuating arm, which has not yet been fitted with a flap is provided, and said assembly securing device comprises a braking device which limits the opening speed of said vacant actuating arm.
Abstract:
A floating damper assembly operates between first and second associated components. A damper is adjustably mounted in the first component and includes a damper gear engaged with a gear on the second component. The second component defines a guide surface and the damper has a bearing surface engaging the guide surface.
Abstract:
A support device for supporting an upper body of an electronic apparatus is disclosed. The electronic apparatus further comprises a lower body, and the upper body pivotally rotates relative to the lower body. The support device comprises a rotating element disposed on the lower body and having a thread surface, a first gear disposed on the upper body, a second gear meshing with the first gear at one side and meshing with the thread surface of the rotating element at another side, a first resistant torque providing element disposed under the rotating element, and a second resistant torque providing element disposed under the first resistant torque providing element. The first resistant torque providing element and the second resistant torque providing element provide resistant torques in counter directions to gradually dissolve the weight load of the upper body during the opening or closing processes, so as to stably support the upper body of the electronic apparatus.
Abstract:
The invention relates to a hinge comprising a moveable hinge section and a hinge section consisting of a fixed stop section, which are interconnected by at least one joint axis, and comprising a damping device mounted on one of the hinge sections whose translationally or rotatably moveable damping member is acted upon at least in the closure region of the hinge via gear means from the other hinge section. According to the invention for adjustment of the moveable damping member depending on the tilt of the moveable hinge section relative to the at least one joint axis, there is provided at least three moveable gear members are provided, of which one is the damping member itself.
Abstract:
A spindle drive for a movable component includes a threaded spindle which is rotatable about a spindle axis; a spindle nut which engages the threaded spindle; and a transmission element which can be connected to the movable component, the transmission element being fixed against rotation about the spindle axis and being axially drivable by rotation of the spindle nut. An intermediate element, which is fixed against rotation relative to the spindle nut, extends axially with respect to the threaded spindle and is rotatable relative to the threaded spindle. A drive is connected to rotate one of the intermediate element and the threaded spindle; and the other of the intermediate element and the threaded spindle can be fixed against rotation.
Abstract:
This invention relates to an active brake release device attached to the exterior of a door controller, comprising: a first electromagnet, in which a sliding portion can slide to activate a sliding bar when the electromagnet is energized for magnetic excitation; a first and a second actuator, in which the first actuator is located to abut against the break release bar of the door controller, and a sliding pin of the first actuator is yielding biased in the anti-activation direction of the bar; and, the second actuator is limited by a limit means at a fixed position; a second electromagnet, which is used to release the second actuator when it is energized for magnetic excitation; a circuit, which includes a limit-switch and provides instant power to the first electromagnet during the resetting of the device; and a capacitor, which is used to temporarily supply power to the second electromagnet in unexpected electricity failure. Thus, in the instant of unexpected electricity failure, the device will actively release the brake by mechanical force, and shut off the safety door by sliding down with its own weight.
