Abstract:
An opening and closing apparatus for vehicle lid includes a lower base adapted to be mounted on a body panel of the vehicle and arranged to an opening of an inner space of the vehicle, first and second hinge links rotatably connected to the lower base at each one end of the respective first and second hinge links, an upper base attached to the vehicle lid formed for closing the opening of the inner space and connected to each the other end of the respective first and second hinge links, a motor for providing a drive to the first hinge link, a drive transmitting member provided between the motor and the first hinge link for transmitting the drive from the motor to the first hinge link, a normally section torque transmitting mechanism provided between the drive transmitting member and the first hinge link for transmitting the drive to the first hinge link at a point of force reaction through the normally section torque transmitting mechanism after the drive transmitting member is rotated with a predetermined angle while the vehicle lid in a fully-opened state is under closing operation and a close-start section torque transmitting mechanism provided between the drive transmitting member and the upper base for directly pressing the upper base at a point of force reaction through the close-start section torque transmitting mechanism that a distance from a center point of the rotation of the upper base is longer than a distance of the point of force reaction through the normally section torque transmitting mechanism from the center point of the rotation of the upper base before the drive transmitting member is rotated with the predetermined angle while the vehicle lid in the fully-opened state is under closing operation.
Abstract:
A power-operated system for actuating the rear doors or liftgates of motor vehicles includes a strut assembly having two struts, each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut is connected to a powered rotating arm. To open the door, the rotating arms change the angular orientation of the struts such that they have a substantial mechanical advantage. In this position, the force provided by the struts overcomes the weight bias of the door, thus opening the door. To close the door, the rotating arms change the angular orientation of the struts such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore causing the door to fall closed under its own weight bias. A control system for controlling the power-operated system is also disclosed.
Abstract:
A power liftgate drive assembly automatically moves the liftgate of a vehicle between its open and closed positions. The drive assembly is secured to the vehicle at a position near the top of the liftgate. The drive assembly includes a motor that drives a sector gear between two positions. A guide rod is secured to the sector gear to translate the rotational movement of the sector gear into the pivotal movement of the liftgate. A slot extends through the sector gear that allows the liftgate to be moved manually. A latch locks the guide rod in position with respect to the sector gear for automated movement whereas the latch releases the guide rod to move in the slot for manual operation.
Abstract:
The invention relates to a counter (10) for presenting and/or selling goods. The aim of the invention is to provide a means of displacing a module consisting of a system of joint mechanisms (22) which are associated with a glass pane (21) by means of fixing elements (23) between a closed position (20) in which the inside of the counter (13) is covered and an open position (20′) in which it is exposed. Said joint mechanisms (22) are mounted on the supports (15) of the counter (10) in such a way that they can pivot about a horizontal pin (18). In order to ensure that the modular unit is secure in the open position (20′) the joint mechanism (22) is provided with an extended arm (24) which has the swivel bearing (18) on its lower arm section. During the transition from the closed position (20) to the open position (20′), the center of gravity (27) of the module in relation to the swivel pin (18) moves to the opposite side (27′). In the closed position (20), the pane (21) is subjected to a torque which acts in the closing direction. In the open position (20′), a torque acts on the pane (21) in the opening direction. The pane (2) can no longer fall back out of the open position (20′) into the closed position (20) uncontrollably.
Abstract:
A resistance mechanism suitable for applications such as resistance exercise equipment, cable reels, garage doors and other equipment requiring a resistive force. Resistance packs include circular rims and central hubs connected by deformable spokes. The packs are stacked in pairs with the rims in each pair pinned together and the hubs rotatable relative to one another. Each hub has a spline connection with the hub of the next resistance pack in the adjacent pair. This provides a series arrangement of the resistance packs which allows a long extension of the actuator with the spokes of each pack being deformed only slightly. A spiral pay out pulley for the cord assists in avoiding varying resistance with extension of the cord. The mechanism includes a preload system for applying a preload force to the resistance packs and a visual indicator for indicating the level of the preload force. An alternative construction involves forming the resistance packs in a single base having a pair of the resistance devices housed together. The devices may include arms connected by peripheral portions to provide loops that are looped around walls on the base to avoid a need for a bonded connection of the arms to the rims.
Abstract:
A lifting apparatus for a two-leaf folding flap, whose upper leaf is hinged to a top or partition wall of a cupboard around a horizontal first axle and whose lower leaf is pivotally connected to the upper leaf around a second axle parallel to the first axle, comprises at least one two-armed lever which is pivotally mounted to a side body part around a horizontal pivot axle and whose longer arm is linked to the lower leaf. One end of the compressing spring element is pivotally connected to the body part and the other end is pivotally connected to the lever. To prevent the leaf from coming into contact with the end surfaces of body parts of the cupboard closed by the folding flap, the lever is guided in a longitudinally displaceable manner on its pivot axle and the shorter lever arm is guided in a cam guide fixed to the body via a slide block or a roller.
Abstract:
An actuating arrangement for opening and closing a hinged motor vehicle panel has a fluid drive, a control unit, and a sensor unit. The hinged motor vehicle panel is movable between a starting position and an end position, and the control unit evaluates start signals from the sensor unit and stopping the movement of the motor vehicle panel in an intermediate position. The start signals from the sensor unit correspond to current angles of opening of the hinged motor vehicle panel, and predetermined angles of opening of the hinged motor vehicle panel define certain criteria. It is possible to set at least the angle of opening of the intermediate position via the control unit.
Abstract:
An actuating arrangement and method for opening and closing a hinged motor vehicle panel utilizes a controllable fluid drive and an uncontrolled fluid drive. The hinged motor vehicle panel is driven during opening from a starting position to a predetermined opening angle by the controlled fluid drive and, after reaching the predetermined angle of opening, is driven into its final position exclusively by the uncontrolled fluid drive.
Abstract:
A method for operating a hydraulic closure system for a motor vehicle includes automatic opening and closing, as well as manual closing, of a closure pivotally mounted to an opening frame defining a closure opening in the motor vehicle. The system used in the method includes at least one hydraulic actuator assembly attached at opposite ends thereof to the closure and the opening frame, respectively. A motorized hydraulic pump inputs energy to the actuator to move the closure from the opened position to the closed position, and a biased energy storage system inputs energy to the actuator to move the closure from the closed position to the opened position. In a preferred embodiment, the pump is activated by relatively slow manually generated movement of the closure from the opened position toward the closed position. Also, an obstacle detection mechanism detects obstacles interfering with closing of the closure based on monitored pressure in the system. A level detection and compensation feature adjusts the amount of energy stored in the biased energy storage system for opening the closure based on the detected inclination or declination of the vehicle so that the amount of energy stored is commensurate with the amount required to open the closure.

A display case having a tubular framework with a display window pivotally mounted thereto has a lifting and supporting mechanism for the display window including a strut member having a rod end and a cylinder end. A hinge is pivotally mounted to the cylinder and is adapted to be secured to the display window. A strut body slidably receives a strut member and hinge thereon. A retention arrangement pivotally connects the rod end of the strut and the hinge to the strut body so as to define a strut module which is slidable into and out of the tubular framework of the display case.
