Abstract:
A drive arrangement (10) has first and second wheels (12, 14) and an endless loop member (16). The path of the member (16) is defined in part by a third wheel (18), between the wheels (12, 14). The wheel (18) is movably mounted so that the length can be changed for the path of the member (16) as it passes around the wheel (18), between the wheels (12, -14). Accordingly, the member (16) can be tightened or slackened around the wheels (12, 14), so that the wheels (12, 14) can be coupled to convey drive from one to the other, through the member (16), or disengaged, so that drive is not conveyed.
Abstract:
A cable tensioner includes two cams mounted to face each other that pivot about a common spindle. A torsion spring is centered on the spindle. The torsion spring includes a first end in abutment with a first cam and a second end in abutment with a second cam. The torsion spring applies a torque onto each of the cams to reduce an angular distance between the cams when a cable exhibits insufficient tension. The cable tensioner is placed in a window regulator mechanism to simultaneously tension a lower cable and an upper cable of the device. Furthermore, the tension of one cable through the cable tensioner is reversible since the tension of each cable is balanced with the tension of the other cable.
Abstract:
A device for adjusting a window regulator in a vehicle door, having a profiled base element (110) positionable on a lower section of the vehicle door and provided with a first elongate hole (111b) in its lower side and a second elongate hole (111a) in its upper side. A slider (112) slidingly moves within the base element (110) and includes a hole (113) aligned with the first elongate hole (111b). A screw extends through the hole (113) in the slider and the first elongate hole (111b) aligned therewith. A bolt (116) is fixedly attachable to the window regulator extending through the second elongate hole (111a) and includes a threaded rod engaging the threading of screw (114). The screw (114) can be turned from a first position, in which it does not engage the slider (112), to a second position, in which it engages the slider (112) with the first screw end (114b). The device provides for simple compensation of tolerances in connection with the vehicle door and for the window regulator.
Abstract:
An automatic opening/closing apparatus for vehicle is downsized, and cost of the automatic opening/closing apparatus is reduced by reducing the number of its components. A driving drum is rotatably accommodated in a main body case of a driving unit, and one ends of cables are connected to a sliding door and the other ends are wound around the driving drum. An electric motor is attached to the main body case, and the driving drum is driven for rotation. A tensioner mechanism applying a predetermined tension to the cables is accommodated in the main body case. A control device, including a control substrate and a substrate case for accommodating the control substrate, is disposed to be overlapped on an axial-directional side of the driving drum to a portion of the main body case for accommodating the tensioner mechanism, whereby an operation of the electric motor is controlled by the control device.
Abstract:
A vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a pluraity of pulleys across which wires are laid are provided at upper and lower sides of a base panel. The glass plate is moved up and down by driving the wires, the glass plate is prevented from moving in a vehicle inward direction when the door is closed. Wire fixing portions are prevented from being damaged by great upward and downward stroke movements of the glass plate. Furthermore, the wires are prevented from slackening when the wires are driven and stopped by a supporting rod along an upward and downward movement locus of the glass plate, and by a contact member which has no contact with the supporting rod. Trumpet-shaped guide portions are located at hole edges of the wire fixing portions, and the circumferential surfaces of a tensioner are V-shaped for eliminating slack in the wires.
Abstract:
An improved hydraulic lifting sectional security door, capable of being installed at an entry space to a room, comprising a pair of profiles (PRF) near to each frame (STP) of the entry space, a series of panels (PNL) articulated together and a device or group (GP) for lifting the panels (PNL), which includes a hydraulic cylinder (CI), to which fixed and mobile lifting pulleys (PL1, PL2, PL3, PL4) are fixed; according to the invention the lifting cables (FA1, FA2) start from stops (FE1, FE2), which are preferably next to the cylinder (CI) and their exit in the direction of the return pulleys (PU1, PU2) takes place in a balanced manner, on the two outer sides of the lifting pulleys (PL1, PL2, PL3, PL4), so as to be able to obtain a reversible container (CAS), which allows the hydraulic cylinder (CI) and the exit of the hydraulic tube (TU) to the right or left of the entry space, according to the user's desires and requirements.

This is realized by providing a supporting rod along an upward and downward movement locus of the glass plate and a contact member which has no contact with the supporting rod, by forming trumpet-shaped guide portions at hole edges of the wire fixing portions, and by V-shaping the circumferential surfaces of a tensioner for eliminating slack of the wires.
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.
