Abstract:
The electrical door driving device mainly contains a shaft having threads with a smaller pitch at the two ends and a larger pitch in the middle. A guiding element is configured on the shaft with a guide pin running vertically through the guiding element and into a groove of the shaft. An end of the shaft is connected to a motor and a leaf is connected to the guiding element by a vertical rod. When the motor engages the shaft to spin, the guiding element, and thereby the leaf, is moved as the guide pin traverses the groove of the shaft. As the threads of the shaft are denser at the ends of the shaft, the leaf moves slower when the door starts to close (or when the door starts to open) and when the door is about fully closed (or when the door is about fully opened).
Abstract:
Movable partitions and movable partition system include a header assembly and a movable partition. The header assembly may comprise an elongated overhead track including a first channel, a second channel, and a central channel between the first and second channels. A plurality of support bracket attachment features may be included with at least one support bracket attachment feature on each of an outer surface of the first channel and an outer surface of the second channel. A support bracket may be coupled to each of the support bracket attachment features. The movable partition may comprise a plurality of panels connected to one another with hinge-like member and may be suspended from the overhead track. Embodiments of overhead tracks and methods of forming header assemblies are also disclosed.
Abstract:
A damper device for retarding pivotal advancement of a hinged wall piece towards a hinging wall piece includes a tubular housing adapted to be mounted on one of the hinged and hinging wall pieces, a resisting seat with a resisting end, a position shifting mechanism disposed to couple the resisting seat to the housing such that the resisting seat is retainingly shiftable relative to the housing to permit movement of the resisting end, and a damper unit which has impacted and abutment ends and which is compressible such that, upon being pushed by an impact force, the impacted end is thrust towards the abutment end so as to acquire a damping force to counteract the impact force. The abutment end is engaged and moved with the resisting end for adjustment of the damping force.
Abstract:
In an embodiment an adjustable window regulator lifter plate assembly is provided. The adjustable window regulator lifter plate assembly includes a base, a window holder and a cross-car orientation adjustment mechanism. The base is configured for movement along a path. The base has an inboard side and an outboard side. The window holder is configured to receive and hold a vehicle window. The window holder is movably connected to the base. The cross-car orientation adjustment mechanism is operable by a cross-car orientation adjustment tool and is operatively connected to the window holder to control the cross-car orientation of the window holder. The cross-car orientation adjustment mechanism includes a cross-car orientation adjustment mechanism tool-receiving member configured to receive the cross-car orientation adjustment tool. The cross-car orientation adjustment mechanism tool-receiving member is accessible from the inboard side of the base.
Abstract:
A device for adjusting a window regulator in a vehicle door, having a profiled base element (110) positionable on a lower section of the vehicle door and provided with a first elongate hole (111b) in its lower side and a second elongate hole (111a) in its upper side. A slider (112) slidingly moves within the base element (110) and includes a hole (113) aligned with the first elongate hole (111b). A screw extends through the hole (113) in the slider and the first elongate hole (111b) aligned therewith. A bolt (116) is fixedly attachable to the window regulator extending through the second elongate hole (111a) and includes a threaded rod engaging the threading of screw (114). The screw (114) can be turned from a first position, in which it does not engage the slider (112), to a second position, in which it engages the slider (112) with the first screw end (114b). The device provides for simple compensation of tolerances in connection with the vehicle door and for the window regulator.
Abstract:
A window regulator includes at least one rail and at least one movable carriage for attachment to a movable window, each movable carriage movably attached to a respective rail for movement along the rail. A driving mechanism is attached to the movable carriage for moving the movable carriage along the rail in a regulated manner. An adjustable stop is attached to the rail, the adjustable stop positioned to engage a portion of the respective movable carriage/window assembly attached to that rail, to prevent further movement of the movable carriage/window assembly in one direction.
Abstract:
A hinge buffer device includes a casing, a slide, a buffer and an adjustment. The casing comprises a first end, a second end, a pair of lugs, a threaded hole, and a sliding trough. The lugs are disposed at two sides of the first end of the casing. The threaded hole is formed at the second end of the casing. The sliding trough is located between the first end and the second end of the casing. The slide comprises a compartment, a pair of sliding sections at respective sides to be engaged with the sliding trough of the casing. The buffer is a cylinder to be mounted in the compartment of the slide. The buffer comprises a piston rod secured to the slide. The adjustment is connected to the slide, and comprises a bolt to be engaged with the threaded hole of the casing.
Abstract:
A shaft such as a worm drive shaft for a movable barrier operator is disclosed. The shaft includes at least two shaft segments having connection ends. The shaft segments include respective connection ends permitting a first connection end to be joined with a second connection end by inserting a portion of at least one of the connection ends within the other connection end along the longitudinal axis of the shaft. The shaft segments may be retained by a resiliently expandable connector such as a snap ring. The connector may expand to permit the joining and then contract to be received within a surface recess on a connection end. The connector may be part of or pre-assembled on a connection end, such as by being positioned within a surface recess thereof. The connector may provide a pre-determined position for joining the first and-second connection ends.
Abstract:
A driving system for a garage door includes a track having an end fixed on an inside of a wall and has an open side that faces upward. A driving assembly is movably received in the track and driven by a motor. The driving assembly includes a connection member to which two ends of a power transferring member are connected. A U-shaped member is movably engaged with the track from an underside of the track and two sides of the U-shaped member are connected to the driving assembly. A link is pivotably connected between the U-shaped member and the garage door. The power transferring member reeves a gear which is rotatably connected to the track and the motor has a driving shaft which is conveniently extended through an opening of the track and engaged with an engaging hole of the gear.
