Abstract:
This window regulator is constituted by a rail which is obtained in a single piece, by injection of a light-weight metallic alloy, integrating a great many of the window regulator components, like for example: the supports (1) for fastening the window regulator to the door of the vehicle, the support (2) and anchoring elements (6) for the drive motor used in the systems of electric window regulators, the coupling elements (5) of the Bowden system for tensioning the cable (4), necessary in the manually operated systems, the housing (8) for the cable-winding drum, the sliding or diverting elements (3) of the cable (4). Moreover, the rail leaves the mould, with an appropriate curvature for correctly following the window. glass, even though the latter has a very complex shape. Thus, the same rail can be used indistinctly for manual window regulators, electric window regulators and dual rail window regulators.
Abstract:
A folding and spreading system for a half spread folding comprises an upper and a lower guider for making the folding door move in a close or open direction; a first wire guider provided at the depth portion of each door leaf in a predetermined distance from a neighboring first wire guider, and a second wire guider installed coaxially to the first wire guider; a folding motor and a spreading motor provided at both end frames of the folding door, respectively, and having a reel at each rotational shaft of each motor; and a winding wire and a releasing wire extended diagonally through each of the wire guiders of each door leaf, respective end of the wires connected to the wire guider and to the reel of the motor, respectively, in order to fold and spread the adjacent two door leaves around the hinge.
Abstract:
A mechanism and method for operating a track-mounted door is disclosed. The mechanism includes a pair of side drums that are connected by first cables to the bottom of the door. The side drums are coaxially mounted on a shaft for simultaneous rotation with a pair of cable drums. The cable drums are connected to high pressure gas struts by second cables. Each second cable is carried around a shiv wheel that slides along a guide track as the second cable moves. Each shiv wheel is operatively connected to one of the gas struts. As the shiv wheel moves along the guide track toward the cable drum, the gas strut is charged. As the shiv wheel moves away from the cable drum, the gas strut is discharged. A standard electric motor and screw driven lift-arm is used to initiate the opening and closing of the door. The charged gas strut stores sufficient energy to overcome friction and gravity to assist the electric motor and lift-arm to open the door.
Abstract:
A reel drum is rotatably supported on a board, and a tensioner case is detachably mounted to the board in the vicinity of the reel drum. Wires are extended from the reel drum in directions opposite to each other. A pair of tension rollers pressed onto the respective wires and roller holders rotatably supporting the respective tension rollers are attached to the tensioner case to be allowed to move in directions substantially orthogonal to the respective wires when the wires are tensioned. Moreover, the tensioner case is provided with biasing means to bias the roller holders in directions that the tension rollers are pressed onto the respective wires. The biasing means is a torsion spring. A contact portion of each roller holder which a wire end extended portion of the torsion spring is in contact with has an angle shape with a ridge aligned in a direction orthogonal to the wire end extended portion of the torsion spring.
Abstract:
A device (1) for use with a cable-operated door (3), such as garage doors (3) and the like, and a door assembly including the same. 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 opposite braking arm (19) and lever portion (20), the lever portion cooperating with the tensioned cable (3) so that in the event of a loss of tension in the cable (5), the braking arm (19) is urged onto an adjacent rail (7) via biasing means (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 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 first hinge portion position 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 cable tension sensing apparatus is mounted on a wall having a door opening. The jack shaft garage door operator includes a drive unit having an electric motor for driving a jack shaft mounted above a door opening. A pull-up cable drum is connected to the jack shaft and has a multi-strand steel pull-up cable that may be payed out to lower a door or wound up to raise the door. The cable tension sensing apparatus includes a cable guide to retain the cable a substantially fixed distance from the wall and a spring driven cable follower which urges against the cable extending between the drum periphery and the cable guide. An alerting switch is connected to the cable follower and sends a signal indicating loss of cable tension when the cable follower moves beyond a predetermined distance. Additionally, the movement of the cable follower moves a door blocking arrangement to a position to block movement of the door when being raised without use of the motor.
Abstract:
A window regulatoR (10) for operating a window pane of vehicle comprises a base plate (12) having a guide rail (20). A lifter plate (26) is slidably coupled to the guide rail (20) and adapted for supporting the window pane. A motor assembly (32) is secured to the base plate (12) and includes a drive housing and a power motor. A drive shaft, rotatably journaled to the drive housing, has a disc flange supporting a cylindrical shaft and a key shaft spaced from and parallel to the cylindrical shaft. A top and bottom cable (34, 36) drum are supported on the drive shaft, each of the cable drums including a key slot for aligning with and receiving the key shaft therethrough. The lifter plate is secured to the cable (38) between first and second pulleys (22, 24). A pair of compression springs (64) are coupled to the respective cable drums in opposite directions and maintaining tension on the cable.

A opening and closing device 10 for sunroofs of an automobile, which has a pair of rails 17a and 17b, a lid 13 for opening and closing an opening 12, right and left cables 26 engaged to a lid 14 and arranged along the rails 17a and 17b, and a drive mechanism 36 for driving the cables in a reciprocating manner. The cables 26 construct a closed loop arrangement with bypassing the opening 12 of the loof of the automobile. One of the cable 26 coming out of the drive mechanism 36 is arranged to the right-side rails 17b, bridged to the left side lail 17b, reversed at the base end of the left side lail 17a and returned along the same route to the drive mechanism 36.
Abstract:
In the present control method, by measuring the sliding quantity of a sliding door until the sliding door reaches a door-open end DOE after passing a holder check point HCP, a distance Y from the HCP to the DOE is found. A distance Znull from the HCP to the opening speed final decelerating position FDP is found from the relation between the distance Y and a specified distance Z by calculation. By the next door opening operation, when the sliding door has passed the HCP and the sliding quantity from the HCP becomes equal to the distance Znull, the controller 32 judges that the sliding door has reached the final decelerating position FDP, and decelerates the sliding door.
