Abstract:
A door window system is provided. In at least one embodiment, the door window system includes a core module, window track, a window track glass guide operatively engaged with the window track to be guided along the profile of the window track, a bracket integrally formed on the core module, and a pulley attached to the bracket wherein the pulley is in communication with a cable that is attached to the window track glass guide.
Abstract:
Gear unit and motor-driven gear unit for cable window lift system of motor vehicles, comprising drive and gear mechanism which cooperates with the drive and is coupled to rotatably mounted cable drum for winding/unwinding a cable of the system. Diameter of the cable drum of the gear unit ranges from about 22 mm to about 30 mm, preferably from about 24 mm to about 28 mm; gear ratio of the gear mechanism ranges from about 1:38 to about 1:55, preferably from about 1:42 to about 1:51. The cable drum has, on its end face, claws which engage in corresponding recesses on the end face of a worm wheel. Electric motors having maximum driving torque of only about 5.7 Nm can be used. The gear unit size can be reduced by about 40-50%, and it can be standardized for both electric and manual cable window lift systems for front or rear vehicle doors.
Abstract:
A brake device (1) is for use with a cable-operated door (3), such as garage doors (3) and the like. The device (1) is intended to reduce the risk of the door (3) falling, or at the very least slow down its descent, in the event of a failure in the counterbalancing mechanism of the door (3), which is generally represented by a loss of tension in a given tensioned cable (5) operating the door (3). The brake device (1) includes a support bracket (9), and a guiding assembly (15) and a braking assembly (17) mounted onto the support bracket (9). The braking assembly includes a swivel component (18) having a braking arm (19) and a lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of the loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via a biasing spring (21) for anchoring a knife (45) of the braking arm (19) into the rail (7) and stopping, or at the very least, slowing down the descent of the door (3), with respect to the rail (7).
Abstract:
A garage door cable drum is disclosed for a sectional overhead door of a type having a substantially non-linear lift-weight to lift-height characteristic. The drum includes a generally spiral cable groove having a variable minor radius. The groove minor radius at any intermediate point along the groove is sized to provide a lift-cable moment arm that yields a corresponding cable lift force that is slightly less than an instantaneous lift weight of the garage door at any intermediate door elevation.
Abstract:
A modular drive assembly for a sliding door, comprising: a guide track having a hinge slidably received therein; a pair of pulleys disposed on either end of the guide track; a pair of cables each having an end that is secured to the hinge and the other end is secured to a cable drum of a motor drive unit mounted to the guide track, the motor drive unit being configured to rotate the cable drum, wherein the cable drum is also capable of freely rotating within the motor drive unit when the motor drive unit is not rotating the cable drum, wherein rotation of the cable drum causes the hinge to move in the guide track as one of the cables wraps onto the cable drum while the other one of the cables wraps off of the cable drum.
Abstract:
The present disclosure relates to an emergency release for a garage door drive with a sliding latch, wherein the sliding latch is linearly movable by turning a rotary knob.
Abstract:
A sliding door drive assembly for a motor vehicle having a sliding door includes a transmission operatively connected to a motor for transmitting a rotating force to an output shaft. A cable drum is fixedly secured to the output shaft and rotates therewith. First and second cables are wound about the cable drum in opposite directions. The first cable extends from the cable drum forward along the sliding door. The second cable extends from the cable drum rearward along the sliding door. Support guides extend tangentially out from the cable drum to guide the first and second cables outwardly and away from the cable drum along a path minimizing frictional forces. Front and rear pulley assemblies are mounted to the motor vehicle and are operatively coupled to the first and second cables between the sliding door drive assembly and the sliding door for tensioning the first and second cables.
Abstract:
A hinge assembly for coupling a sliding door of a vehicle to a drive unit for sliding the sliding door from an open position to a closed position, the drive unit causing the hinge assembly to slide within a guide track as the door moves between the open position and the closed position, the hinge assembly comprising: a first hinge portion; a second hinge portion, the first hinge portion being pivotally secured to the second hinge portion; a cable attachment being secured to the second hinge portion; and a guide surface disposed on a surface of the first hinge portion, the guide surface being configured to make contact with a portion of a cable having an end secured to the cable attachment when the second hinge portion is in a first orientation with respect to the position of the first hinge portion and the cable no longer makes contact with the guide surface as the second hinge portion moves from the first orientation to a second orientation with respect to the first hinge portion.
Abstract:
A door apparatus includes a door having a hole and configured to be slidable with respect to a vehicle body, a member configured to open and close the hole, a first detector configured to detect a position of the member relative to the hole to determine an openness of the hole, a second detector configured to detect a position of the door relative to the body, and a unit configured to be activated to project from one to another of the body and the door, so as to abut on the another such that the door is stopped from sliding in an opening direction, when the openness is greater than a threshold, and the position is between a full-closed position and a midway position.
Abstract:
An actuating mechanism for moving a vehicle body panel, such as tailgate, between an open and closed position includes a motor having a drive cable coupled to a rod and cylinder assembly to drive the tailgate between the open and closed positions. A mechanical control including a spring and pulley assembly is coupled to the drive cable to allow acceleration during opening or closing movement of the vehicle panel in response to a user input force.
