Abstract:
The invention relates to a drive device (1), essentially including a motor (26) and a gearbox (27, 83) and a control system (123), for the automation of a door, preferably a garage door, with a connection (120) to a force transmitting means (46) revolving within the drive track (4) and driven by means of the motor (26), wherein the gearbox (27, 83) includes a worm (29) and is equipped with two opposing motor connectors (57, 58), to which selectively a motor (26) or (28) or simultaneously both motors (26, 28) can be connected, wherein the motors (26, 28) act upon the common worm (79), the rotational movement thereof being transferred onto a worm wheel (100), which directly or indirectly acts like a gearbox onto the force transmitting means (46).
Abstract:
A window regulator provided in a door of a vehicle to raise and lower a windowpane in the door. The window regulator includes a traveling body that holds the windowpane and travels together with the windowpane, a wire that pulls the traveling body, and a drive mechanism that generates a drive force to wind the wire. The traveling body includes a sub-housing that encloses at least a portion of the drive mechanism. The traveling body includes a recessed groove into which the wire is inserted and which has a depth in a plate thickness direction thereof. The sub-housing is fixed to the traveling body while striding across the recessed groove.
Abstract:
A motor vehicle window lifter is provided with a twistable or bendable guide rail on which a driver to be coupled with a window pane is shiftably mounted and which includes fastening points which are connectable with fastening receptacles of a carrier element. Between the fastening receptacles of the carrier element at least one supporting point is provided. When bracing the fastening points of the guide rail with the fastening receptacles of the carrier element, the guide rail supports on the supporting point and twisting of the initially straight guide rail with a specified degree of twisting and/or bending of the guide rail with a specified bending radius is effected.
Abstract:
In a window regulator, and a method of producing the same, which moves a slider base along a guide rail via wires in accordance with rotation of a drum, includes a fitting portion having a first protrusion and a second protrusion provided on a drum housing which supports the drum, wherein the first protrusion protrudes from an abutting surface of the drum housing with which an end surface of the guide rail can come into contact and wherein the second protrusion protrudes from the abutting surface by a smaller amount of protrusion than that of the first protrusion, and the drum housing and the guide rail are joined by restricting movement of the guide rail in the thickness direction thereof by inserting the guide rail in between the first protrusion and the second protrusion. Workability during manufacturing of the window regulator is thereby improved.
Abstract:
A tilt-up door for a building having an opening including a door frame with vertical track members, cam surfaces extending laterally from the vertical tracks at the upper portion of the tracks and a door sized to span the opening. The door can be pivotally coupled with rollers disposed within the vertical tracks and cam followers extending laterally from the upper portion of the door to contact the cam surfaces. When an upwardly directed motive force acts on the door the cam followers come into engagement with the cam surface to lift the door generally vertically and then rotate the door inwardly as the door is raised into an open raised position.
Abstract:
A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.
Abstract:
A running track device for the displaceable support of at least one first roller carriage and at least one second roller carriage includes a first running track profile with a first roller running track for the displaceable support of the first roller carriage. The running track device further includes an attaching portion for the attachment to a wall above a door opening. A second running track profile is included having a second roller running track for the displaceable support of the second roller carriage and a mounting portion for the attachment of the second running track profile to a counter-mounting portion of the first running track profile.
Abstract:
A folding door with two or more intrinsically rigid folding shutter elements with alternating noncollapsing and collapsing element edges, with at least one guide means which can be raised and lowered on or in one or more guide rail(s), for moving a, in particular the lower, permanently guide rail-adjacent, noncollapsing door element edge, wherein at least one release movement means, which is provided for the initial release movement of the permanently guide rail-adjacent door element edge from the guide rail(s), at the beginning of the opening of the folding door, and for the final advance movement of the permanently guide rail-adjacent door element edge at the end of the closing of the folding door, and an actuation device and method for the same.
Abstract:
An improvement in garage door tracks which includes placing an inwardly pressed hem on the distal ends of the sections of track which surround the gap by which wheels from a garage door are placed into a track chamber. The hems on the distal end provide increased strength and a safer smoother edge. The inward hemming also does not interfere with the roller wheels of the garage door. This further solves the problem of track failure and bulge or crimping and causes less stress on the garage door track. A further innovation is to have strengthening ribs at different locations on the garage door track to provide further strength to the garage door track. A further innovation is to provide strengthening ribs at different locations on the garage door track to provide further strength to the garage door track.
Abstract:
In a sliding door disposed in an opening of a cover surrounding a machine tool,From among two adjacent door panels, at least one of sliding members of the door panel which is located closer to a door frame slides on a door frame guide track, whereas at least one of sliding members of the door panel which is located farther from the door frame slides on the door frame guide track, and at least one of the remaining sliding members slides on the door panel guide track. Thus, guide means can be prevented from projecting vertically.
