Abstract:
A vehicle door articulating and sliding mechanism is provided that includes a swing arm pivotally mounted via a first bracket to a vehicle structure at one end and a sliding assembly comprising a rotating second bracket mounted at an opposite end of the swing arm. The sliding assembly is slidably engaged to a vehicle door. The mechanism also includes a first flexible link at least partially encircling a first sprocket connected to the vehicle structure and a second sprocket fixed to the vehicle door. The mechanism further includes a second flexible link fixed to the vehicle door at one end and fixed to the vehicle structure at the opposite end. The second flexible link at least partially encircles a cam, wherein the first flexible link and cam provide a catch that engages the cam to accelerate movement of the door during opening.
Abstract:
A drive unit for a power operated vehicle closure has a track, a guide moveable along the track, a link attached to the guide at one end and adapted to be attached to the vehicle closure at the opposite end, and a motor assembly for moving the guide along the track. The motor assembly has an electric motor and a speed reducer driven by the electric motor that has a first stage and a second stage. The first stage includes a belt drive and the second stage is a spur gear set. Alternatively the first stage is a worm gear and a mating helical gear. The worm gear preferably has a high lead angle and a high number of leads. The speed of the electric motor is reduced to about 1000 rpm or less in the first stage permitting the use of spur gears in the second stage while retaining quiet operation.
Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
Abstract:
The invention relates to a drive device, particularly for doors, garage doors, etc., comprising a guide device, particularly a rail or guide rail, extending in movement direction of the door. The invention is characterised in that the feed means comprises a first insert body which can be plugged at the ends of the guide rail into this and is provided with a connecting cable and which is held at the guide rail end and constructed in such a manner that it fulfils its function not only at one end of the guide rail, but also at the other end of the guide rail.
Abstract:
A sectional door having a door frame, a door panel comprising sections coupled to another in articulated manner, a weight equalization device coupled to the door panel, and an electrical door drive for opening and closing movements of said door panel. The uppermost section in the closed position of the door panel, is guided on running rails as the header section, wherein said rails extend essentially horizontally up to the door frame, and have a vertical end segment on the frame side. The other sections that follow below the header section are guided in guide rails that have a vertical segment along the door frame, a horizontal segment parallel to the running rail that holds the header section, and an arc that joins the two segments. With this device, the door drive is attached to one of the sections connected below the header section, and has at least one power take-off shaft having an impeller at the end. The driven impeller engages in the guide rail and moves the door panel.
Abstract:
A multi-link connector which is particularly suitable for use with a window operator. The multi-link connector includes a plurality of links (12) joined together by a joining arrangement (11). The links (12) include a base (13) and a pair of oppositely disposed walls (14) so that the links (12) form a generally channel shaped elongate length. The joining arrangement (11) provides a plurality of drive elements (11a) which extend transversely between the walls (14) and are accessible through a gap (16) formed between the walls.

Abstract:
A door driving-mechanism torque transmission (20, 40, or 50) for transmitting torque from a door-driving motor assembly, especially a geared motor (36), to a shaft (33) connected to a door panel (31). A driving component rotates around an axis and can be engaged with the door-driving motor assembly. A driven component rotates around another axis and can be engaged with the shaft. A bearing assembly accommodates both components mounted on separated axes of rotation. There is a coupling connection (2) between both components. The object is to promote smooth operation and decrease frequency of repair. The bearing assembly (4 or 51) is accordingly provided with a driving-component bearing half (5 or 52) that the driving component (1) is mounted on and with, separated therefrom, a driven-component bearing half (6 or 53) that the driven component (3) is mounted on. The bearing halves (5 & 6 or 52 & 53) are connected elastically for the purpose of attenuating torsional vibrations and impacts. The invention also concerns a motorized door-driving mechanism provided with such a torque transmission as well as a door provided therewith.
Abstract:
A multi-strand chain forms a chain drive including at least two chains so that the chain drive may communicate a force when the chain is pushed or pulled. The chains may be separated or disengage so as to be stored compactly. The chains may be engaged to form the chain drive so that the chain drive is substantially rigid and in a linear orientation, and pivotally connected chain links may not substantially rotate relative to each other and may not be deflected substantially from the linear orientation. The chains may be engaged and disengaged by rotating around sprockets which deliver the force to the chain drive. The chain drive may be utilized as a garage door system for raising or moving laterally a garage door or movable barrier with the chain drive in compression.
