Abstract:
A mounting method and apparatus provides a simple and compact mount for attaching a power or manual window drive mechanism within a door module. The drive mechanism can be removed from a door panel without having to remove the driven mechanism that lowers and raises the window. The drive mechanism is positioned on one side of the panel and the driven mechanism is positioned on an opposite side of the panel from the drive mechanism. A retaining assembly retains the driven and drive mechanisms to the panel such that the drive mechanism can be selectively detached from the panel without detaching the driven mechanism from the panel.
Abstract:
A cable control device (10, 110) in a sectional overhead door (11) having a motor-driven counterbalance system (30) including a spring-loaded drive shaft (31), cable drums (35) carried by the drive shaft, cables (C) attached to and interconnecting the cable drums and the door and forming and releasing cable wraps of the cable on the cable drums upon raising and lowering of the door, and shrouds (10, 110) associated with the cable drums engaging the cable wraps through substantially the circumference of the cable drums to maintain axial alignment of the cable wraps with the cable drums in the event of the development of slack in the cables.
Abstract:
A drive unit, for moving up and down a vehicular window pane, including a drive motor, a worm wheel, a bracket, an elastic body, and a shaft member. The drive motor includes a motor shaft fixed to a worm. The worm wheel is rotated by the driving force of the drive motor rotatably engaged through the worm. The bracket, on which the worm wheel is mounted, includes an engaging portion, bent and raised transmitting leaves pressed by the elastic body, cutout portions, and closure portions closing the respective cutout portions. The elastic body is provided between the worm wheel and the bracket, and is rotated together with the worm. The shaft member engages with the engaging portion of the bracket.
Abstract:
A cable control device (10) for a sectional overhead door (11) having a motor-driven counterbalance system (30) including, a spring-loaded drive shaft (31), cable drums (33) carried by the drive shaft, cables (C) attached to and interconnecting the cable drums and the door and forming and releasing cable wraps on the cable drums upon raising and lowering of the door, and retainers (60) associated with the cable drums engaging a portion of at least one cable wrap to maintain engagement of the cable wrap with the cable drums in the event of the development of slack in the cables.
Abstract:
A window regulator apparatus for moving a window glass in the vertical direction of a vehicle door incorporates a plurality of pulleys rotatably supported on the vehicle door, a drum rotatably supported to the vehicle door, and a cable jointed to the window glass, guided to the pulleys and looped around the drum. The drum includes a first spiral groove which supports one end of the cable and a second spiral groove which supports the other end of the cable. The second spiral groove is formed to spiral in a direction opposite the first spiral groove. The extending points of the cable relative to the first spiral groove and the second spiral groove are defined to gradually change where the cable releases from the drum in the radial direction of the drum by the rotation of the drum.
Abstract:
An actuator assembly for a powered sliding door system for an automotive vehicle. The actuator assembly includes a housing having a cavity and a first cable reel and a second cable reel disposed in the cavity. The first cable reel is operatively connected to one end of a cable and the second cable reel is operatively connected to another end of the cable. The actuator assembly includes a transmission assembly being disposed in the cavity and operatively connected to either the first cable reel or the second cable reel. The actuator assembly includes a motor operatively connected to the transmission assembly for rotating the first cable reel and the second cable reel. The actuator assembly further includes a motor bracket operatively connected to the transmission assembly and enclosing the motor. The motor bracket is adjustable relative to the housing to form either a right-hand assembly, left-hand assembly or intermediate assembly for a right-hand and left-hand sliding door for a powered sliding door system.
Abstract:
A cable drive for a motor-vehicle sliding door has a pair of cable sections of predetermined diameter and each having one end attached to the vehicle and an opposite end, a pin fixed on the vehicle, defining an axis, and having a screwthread of a pitch at least equal to the cable diameter, and a gear having a core threaded onto the pin. A pair of coaxial drums having smooth outer surfaces are axially coupled to but rotatable on the core and are each connected to a respective one of the opposite ends of the cable sections. A spring is engaged between and urges the drums rotationally oppositely to tension the cable sections. Interengaging formations on the gear and on the drums rotationally couple the drums to the gear and a reversible drive motor coupled to the gear simultaneously rotates the gear about the axis, axially displaces the gear on the pin, winds up one of the cable sections on the surface of the respective drum, and unwinds the other of the cable sections from the surface of the respective drum.
Abstract:
A cable drum assembly comprises a cable drum for a cable-driven apparatus such as a cable window lifter, in particular of a motor vehicle, which automatically compensates for cable slackness without deforming the window lift system. The cable drum has the advantage that it only removes the so-called genuine cable slackness present when the window lifter is in the relaxed state. The cable drum has a part for compensating the cable slackness which can be moved in relation to the outer cable drum wall and is disposed in a guide inside the cable drum. The part may be connected with one cable end of the cable loop, and that when a load is placed on the cable drum by the cable, the part is arrested on the cable drum. When the cable drum is unloaded, a spring urges the part so as to take up cable slackness. In other embodiments, the part presses against the outer cable drum wall and irreversibly increased its diameter when it is unloaded or rotates with respect to the cable drum and winds in slack cable when the drum is unloaded.
Abstract:
A power window drive device, including a motor, a worm wheel, a drive drum, and the like, whose manufacturing cost is reduced and which has a reduced size. A rotary shaft, driven by a motor, has a flange extending outward and a spline extending from the flange to the end of the rotary shaft. A drive drum, axially coupled to the rotary shaft, has a shaft hole with a spline and resiliently deformable hook pieces. The hook pieces engage the flange of the rotary shaft, thereby making the rotary shaft immovable in the axial direction. By inserting the end of the rotary shaft into the shaft hole of the drive drum, thereby coupling the splines and making the hook pieces engage the flange of the rotary shaft, the rotary shaft is made immovable with respect to the drive drum in both the axial and the circumferential directions. With this construction, there is no need of separate coupling elements, and the work to assemble the device is simplified.
Abstract:
A power operating system for a vehicle door includes a motor operable to power the door open or closed. When a manual movement of the door a predetermined distance is detected while the motor is inactive, the motor is energized so as to move the door in the direction of the detected movement to complete the manually initiated door movement.
