Abstract:
A vertically movable workpiece support device has a ratchet wheel with a larger diameter than the outer diameter of a driving sprocket wheel and is concentrically attached to an end surface of a boss portion in the driving sprocket wheel. A pair of left and right bearing members are provided side by side, on a side on which the free end side of a drive chain is horizontally extended with respect to the driving sprocket wheel, so as to sandwich a horizontally extending path section of the drive chain. A movable pawl is pivotally supported between the pair of left and right bearing members and engages with the ratchet wheel to block the rotation of the ratchet wheel caused by the movement of the drive chain when the workpiece support base is lowered. An actuator switches the movable pawl to a non-action position with respect to the ratchet wheel.
Abstract:
A shelter and associated methodology for operating a shelter that is selectively positionable between an operable raised mode and an idle lowered mode. The shelter has an outer frame with a first upstanding perimeter wall defining an open top. An inner frame has a second upstanding perimeter wall nested within the first upstanding perimeter wall in the lowered mode. Means are provided for raising the inner frame through the outer frame's open top and above the outer frame in the raised mode. The shelter can further include a second inner frame having a third upstanding perimeter wall nested within the second upstanding perimeter wall in the lowered mode. In that case, the means for raising is further configured for raising the second inner frame through the inner frame's open top and above the inner and outer frames in the raised mode.

A storage device for a vehicle is disclosed. In one embodiment, the storage device has an exterior housing, an interior container, and a scissor lift mechanism. The scissor lift mechanism is located within the exterior housing and is operatively connected to the interior container. The scissor lift mechanism has a raised position and a lowered position. The interior container is within the exterior housing when the scissor lift mechanism is in the lowered position. The interior container is at least partially located outside the exterior housing when the scissor lift mechanism is in the raised position. The scissor lift mechanism includes crossed bars that pivot about a bolt or pin in scissor-like fashion to raise or lower the interior container. An actuator pivots the cross bars to the raised position and is oriented and connected to the crossed bars to have an upward vertical force component throughout the raising operation.

Abstract:
A lifter is provided with operating levers, which, against driving forces of actuators that switch the ratchet pawls to unengaged orientations, switch the ratchet pawls to engaged orientations of being engaged with ratchet gears, is provided with a link mechanism, which, when a workpiece support base is being lowered by collapsing motions of a pair of right and left crosslink mechanisms supporting the workpiece support base and a difference arises in movement amounts of movable support shafts at lower end sides of the respective crosslink mechanisms, converts the movement amount difference to an operating force of the operating lever at the larger movement amount side, and is such that by the operating lever at one side being driven by the link mechanism, the operating lever switches the ratchet pawl at the larger movement amount side to the engaged orientation.

Abstract:
The subject invention includes a lift system including a first scissor-type lift assembly and a second scissor-type lift assembly spaced from the first scissor-type lift assembly. The first scissor-type lift assembly includes a first base and a first platform coupled to the first base for movement between elevated and lowered states. The first scissor-type lift assembly includes a first motor operatively mounted to the first base. The second scissor-type lift assembly includes a second base and a second platform coupled to the second base for movement between elevated and lowered states. The second scissor-type lift assembly includes a second motor operatively mounted to the second base. The first and second motors move the first and second platforms between the elevated and lowered states. The lift system includes a controller in communication with the first and second scissor-type lift assemblies to synchronize operation of the first and second motors.
Abstract:
A compensation device of a traction sheave elevator is provided. The elevator includes a compensation rope running from an elevator car to a compensation sheave of the compensation device located in the lowermost part of the elevator shaft around which the compensation rope runs. The compensation sheave is vertically guided with respect to the shaft bottom via a guiding structure, which allows a vertical movement of the axis of the compensation sheave. The guiding structure includes at least one scissor joint arrangement having its lower end adapted to be connected with an elevator shaft bottom and its upper end being connected with the compensation sheave axis. An elevator includes such kind of compensation device. Vertical movement of the axis of a compensation sheave can be obtained with a very low shaft height requirement.
Abstract:
A scissor lift table (1) has a first base element (2) and a second base element (3) and a scissor (4). The scissor (4) has a first scissor part (6) and a second scissor part (7), wherein the first scissor part (6) and the second scissor part (7) are pivotable relative to one another about a scissor axis (5). The first base element (2) and the second base element (3) are connected by the scissor (4) such that a pivoting of the scissor parts (6, 7) relative to one another about the scissor axis (5) causes a change in the distance between the first base element (2) and the second base element (3), wherein the first scissor part (6) is pivotably borne on the first base element (2) using a fixed bearing (10) and the second scissor part (7) is displaceably and pivotably borne on the first base element (2) using a floating bearing (11). The scissor lift table (1) is designed such the first scissor part (6) may be pivotably fixed relative to the first base element (2) about a temporary pivot axis (12) and a mechanical connection (14) between fixed bearing (10) and first base element (2) may be disconnected and the position of the pivot axis is selected such that when the first scissor part (6) is fixed and the mechanical connection (14) is disconnected, reducing the distance between the first base element (2) and second base element (3) causes an increase in the distance between the first base element (2) and the fixed bearing (10).
