Examples of a hinge set for used for mounting a protractible component of a device are described herein. In an example, the hinge set comprises a support hinge and a guide hinge, each having a first end and a second end. The first end of the support hinge is to pivotably couple to the protractible component and the second end of the support hinge is pivotably coupled to a frame of the device. Further, the first end of the guide hinge is to guide the protractile component and the second end of the guide hinge is to pivotably couple to the frame.

A device has at least two components which are movable relative to one another. The first component is equipped with a rotary receptacle and wherein the second component is rotatably received on the rotary receptacle. A third component is coupled to the second component. Two connection units which are movable relative to one another and a controllable braking device are included, wherein the braking device is designed as a controllable rotary brake in order to provide controlled damping of a movement of a door device between a closed position and an open position. The first connection unit is formed on the first component, and the second connection unit is pivotably coupled to the third component. The pivot axis is oriented transversely with respect to an axis of rotation of the second component.

A device for a track- or rail-mounted closure drive assembly can include a lever and cam arrangement configured to drive an engagement member between an engaged position and a disengaged position, the engaged position allowing motor drive of a closure and the disengaged position disconnecting the drive from the motor to the closure; and a rotating body including one or more camming surfaces and one or more peripheral surfaces, the peripheral surfaces including visual indicia to indicate to a user an orientation of the one or more camming surfaces and hence whether the engagement member is in the engaged position or the disengaged position.

The present disclosure illustrates a sectional door driving device including a power assembly, a chassis assembly and a driving assembly. The power assembly includes a motor, a gear set and a control unit, and the power assembly is fastened on a main chassis of the chassis assembly. The driving assembly includes two half-gears respectively in semicircular cylinder shape, and each of the two half-gears has a combination surface which is formed with an engagement assembly, and the two half-gears are engaged by the engagement assemblies thereof to form a circular gear to cover a shaft of a sectional door mechanism. The gear set includes an output gear configured to drive the circular gear and the shaft to rotate. The sectional door driving device can be separated from the shaft easily for repair, and the sectional door driving device can also be installed on the existing sectional door easily.

The invention concerns a damper assembly for a cup hinge having a carrier part and a cylinder-piston unit which comprises a cylinder that is axially displaceable relative to the carrier part and can be reset by means of spring elements, and a piston rod guided in the cylinder and also a cup hinge with such a damper assembly. The carrier element includes an integrated, elastically deformable accommodation web to which the piston rod can be fixed. Furthermore, the carrier element has, at its side opposite the accommodation web, two elastically deformable fixing elements which are arranged spaced from each other, With the present invention, a damper assembly is being developed which can be installed safely and exchangeably into a cup hinge with a small force application and also a cup hinge with such a damper assembly.

Universal rotary actuators (URAs) and door assemblies having the URAs are disclosed. In some embodiments, the URA includes a motor, a worm gear driven by the motor, a worm wheel having teeth that mesh with threads of the worm gear, a pinion gear attached to the worm wheel, drive gear rotatably connected to the pinion gear, an output shaft attached to the drive gear, and a controller assembly disposed between the drive gear and the motor, the controller selectively controlling direction and speed of the motor. In some embodiments, the URA additionally includes a quick release assembly that moves the pinion gear between an engaged position in which the pinion gear is rotatably connected to the drive gear and a disengaged position in which the pinion gear is not rotatably connected to the drive gear.

An image reading apparatus includes a reading unit, a hinge connected to the reading unit, and a cover connected to the hinge. The image reading apparatus further includes a decelerator configured to apply a damping resistance to a particular gear of the hinge, as a planet gear engages with the particular gear during movement of the cover from an open position to a closed position.

The device comprises a main body, fixing means affording the fixing of the leaf to the body, drive means able to drive a body under the effect of motor means, locking means able to move between an active locking position in which they lock the drive means with respect to the body, in the closed position of the leaf, and an inactive unlocking position in which they allow a displacement of the drive means with respect to this body, and partial opening means able to allow a small movement of the fixing means with respect to the drive means, in the displacement direction, from the closed position of the leaf. The device further comprises means for inhibiting the partial opening means, able to immobilize the fixing means with respect to the drive means, at least in translation in said displacement direction, when the locking means are in their inactive position.

A transmission assembly for converting a garage door operator (GDO) from a ceiling mounted configuration to a jackshaft configuration may include an output coupler for operably coupling a drive tube rotatable to alternately open and close a sectional door, a pinion assembly operably coupled to the output coupler via a flexible coupling member, a releasable coupling assembly, a handle, and a cam operated engagement assembly. The releasable coupling assembly may be operably coupled to a motor output shaft of a GDO motor. The releasable coupling assembly may have an engaged state in which rotation of the motor output shaft is transferred to the pinion assembly and a disengaged state in which the rotation of the motor is not transferred to the pinion assembly. The cam operated engagement assembly may be operably coupled to the handle and the releasable coupling assembly to transition the releasable coupling assembly between the engages state and the disengaged state based on a position of the handle.

A vehicle includes a chassis, a door track, a door operatively connected to the door track and adapted to move between a closed position and an open position, and a hinge assembly coupled to the door. The hinge assembly is movably coupled to the door track and includes a first bracket coupled to the door, a second bracket coupled to the first bracket, and a transport assembly coupled to the second bracket and adapted to move along the door track as the door moves between the open and closed positions. The transport assembly includes a coupling member for releasably coupling the second bracket to the transport assembly. Upon movement of the second bracket from the first position to the second position, the door moves to an extended open position with respect to the door track.
