A door component has a controllable rotary damper and two connector units which can be moved relative to one another. One of the two connector units can be connected to a load-bearing construction and the other one can be connected to a movable door device of a vehicle, in order to damp a movement of the door device between a closed position and an open position in a controlled manner. Two mutually engaged spindle units are arranged between the two connector units, one spindle unit being a threaded spindle and the other being a spindle nut. A first spindle unit is fastened rotatably on a coupling rod connected to one of the connector units. A magnetorheological transmission device is arranged between the coupling rod and the first spindle unit, in order to brake a rotational movement of the first spindle unit as required.

A guide system for guiding a door wing, in particular a folding-sliding-door, movably supported relative to a furniture carcass. The guide system includes a guide rail having a longitudinal direction, the longitudinal direction of the guide rail extending substantially parallel to a depth direction of the furniture carcass in a mounted condition on the furniture carcass. A carrier is provided for movably supporting the door wing, and the carrier is displaceably supported at least over a region along the guide rail. An abutment is provided for determining an end position of the carrier in the longitudinal direction of the guide rail, and an adjustment device can adjust a position of the abutment. The abutment can be adjusted by the adjustment device in the longitudinal direction relative to the guide rail.

A furniture hinge includes a first fitting portion and a second fitting portion, the second fitting portion being pivotally connected to the first fitting portion by a hinge axis member. At least one of the fitting portions includes a base plate to be fixed to a furniture part, and an adjusting plate coupled to the hinge axis member, the adjusting plate being displaceably arranged on the base plate. A preferably pivotally mounted adjustment element can adjust a position of the adjusting plate relative to the base plate along a linear guide to adjust a position of the first fitting portion relative to the second fitting portion. A gap is formed between the first fitting portion and the second fitting portion in at least one relative position of the furniture hinge, and the adjustment element can be actuated by introducing a tool into the gap.

According to one aspect of the invention, an assembly is configured to counterbalance components movable relative to one another, the assembly including a mounting bracket configured to be coupled to one of the components; a follower arm pivotally coupled to a follower arm mounting point on the mounting bracket; a follower coupled to a follower mounting point on the follower arm; means for exerting force between a force exerting means mounting point on the mounting bracket and a force exerting means mounting point on the follower arm; and a cam configured to be coupled to another one of the components in such a way that the follower contacts a cam profile of the cam.

A truck is provided that includes a bed section located rear of a cab section. The bed section is bounded on each side by opposing first and second upward-extending sidewalls, respectively. The truck also includes a truck bed cover that sits over the bed section on at least the first and second upward-extending sidewalls, and includes a door portion to create selective accessibility to the bed section of the pickup truck. The door portion is movable with respect to the first and second upward-extending sidewalls between open and closed positions via an automatic bed cover drive assembly that moves the door portion between open and closed positions according to a plurality of velocities within a predetermined variance.

The present disclosure a hinge blade structure comprises two hinge blades, a connection sleeve, a fixed rod, a screw sleeve, a plug, a damping positioning pull rod, and an air cylinder. The damping positioning pull rod and the air cylinder are both disposed in the connection sleeve and disposed between the fixed rod and the plug, the air cylinder is relatively secured to the plug, the damping positioning pull rod is relatively secured to the screw sleeve, the damping positioning pull rod is slidably connected to an inner side of the air cylinder along a length direction of the connection sleeve, the damping positioning pull rod and the air cylinder cooperate to define an air chamber, the air cylinder comprises an air chamber vent through hole and an air inlet, and a resistance force generated between the air chamber and the damping positioning pull rod achieves positioning.

A driving mechanism for sliding a windowed frame guided by an outer frame. The sliding frame is attached to two vertical racks which engage with two pinions. The pinions are connected with a joint axle driven by a couple of engaged bevel gearwheels connected to a crank or to an electric motor. The joint axle with the pinions can be housed in a recess carved at the lower plank of a static window's frame. A compact motorized option in which each pinion is coupled with a gearbox and both gearboxes are driven by a central electric motor also can be housed entirely in the static window's recess. The motorized options also include: a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm.

In one example, a hinge assembly is disclosed, which may include a first bracket, a second bracket, and at least one shaft to pivotally connect the first bracket and the second bracket. Further, the hinge assembly may include a gear unit coupled to the at least one shaft. Furthermore, the hinge assembly may include a sealant disposed around the gear unit to hold a viscous fluid.

A movable barrier opener system having a multiphase brushless DC motor in the drive assembly is provided. The multiphase brushless DC motor may impart motive force to a movable barrier in response to barrier movement instructions from the barrier operator controller to the drive assembly. The barrier operator controller of the movable barrier opener system is configured to detect a back EMF of at least one winding of the multiphase brushless DC motor and determines a position of the movable barrier and/or determines a torque of the multiphase brushless DC motor in response to the detected back EMF. A position sensor and a back EMF sensor module provides actual operating parameters to the controller.
