摘要:
A touch button switch includes a body (10) having a conductive actuator (28) slidable from one end against a surface (62) to actuate a switch (61) on a board (52) which is held in place by hook latches (53) engaging mortises (55) in the circuit board. The surface (62) may provide conduction from the touch pad to electronic motionless switch circuitry (66) so that the touch button is usable either as a tactile switch touch button, as a motionless touch button, or both. Or, the actuator can be blocked from sliding by means of a spacer (68); and the switch (61) may be replaced by a structure (61a) holding an electrically conductive surface (62a), or not: either way, the touch button will then operate only as a motionless touch button. Or, the surface (62) can be disconnected (65) from the circuit (66), or the circuit (66) can be not installed, to operate only as a tactile switch touch button.
摘要:
A steering angle of an elevator sheave on a shaft is adjusted at installation and subsequently during maintenance by one of several embodiments. In one embodiment, a bolt with a jam nut is adjusted to position the shaft precisely. In another embodiment, a tee bracket is anchored to a hoistway wall, and a jack bolt with shims is used to adjust the vertical placement of the long beams that support the elevator car frame and therefore the shaft.

An elevator machine mounting system for use in a machineroom-less elevator system includes a two-piece frame that is anchored to an elevator hoistway. The first frame piece is permanently anchored to the hoistway wall. The frame is anchored at the top of the hoistway and at the floor slab of the top landing. The first frame piece includes top counterweight rail brackets and a portion of the rail bracket for the car and counterweight at the top landing level. The first frame piece also includes a counterweight dead-end hitch and a controller/drive mounting. The second frame piece is fitted to the first frame piece after the elevator machine is mounted to the second frame piece. The second frame piece is adjustable postwise with respect to the first frame and then bolted thereto.

A touch button switch includes a light conducting body (10) having a conductive actuator (28) slidable from one end against a surface (62) to actuate a switch (61) on a board (52) which is held in place by hook laches (53) engaging mortises (55) in the circuit board. The circuit board has LEDs (58) which illuminate the rear edge of the body, which causes the light to be visible at its front surfaces 20, 21.
摘要:
A single support device (30) is adapted to support and secure a machine (34) at least one sheave (38) and a plurality of termination members (44, 46). The single support device (30) is conveniently installed within a hoistway (26) or within a machine room (90). The machine (34) and sheave (38) may be premounted to the support device (30) and the entire assembly can be lowered into position by crane (300).
摘要:
The present invention includes a method and a device for transporting an elevator car drive machine within an elevator hoistway. The drive machine is secured to a movable carriage located in the hoistway and the carriage is moved in a horizontal direction of travel to move the drive machine horizontally within the hoistway.
摘要:
A roller guide assembly for an elevator system includes a plurality of rollers and a damping subassembly. The damping subassembly includes a plurality of dampers and a sound isolation mechanism. The sound isolation mechanism interconnects the dampers and provides sound isolation between the rollers and the elevator car. In a particular embodiment, the sound isolation mechanism includes a friction bar that interconnects the rollers and dampers.
摘要:
An elevator system includes an elevator car with a plurality of roller guide assemblies attached thereto. The roller guide assemblies guide the elevator car vertically within a hoistway along a plurality of guide rails. Each roller guide assembly includes a friction damping subassembly to minimize vibration and lateral movement of the elevator car. The friction damping subassembly includes a grounding bar and a friction damper attaching onto a shaft of each roller in the roller guide assembly. The friction damping subassembly dissipates energy and improves the ride quality of the elevator car.
摘要:
A structural system for elevator assemblies includes a horizontal compression member positioned near the top of the elevator hoistway for reacting to inwardly directed tension loads and moment forces applied to the hoistway wall and connection components resulting from the elevator vertical load. The horizontal compression member includes a rigid member positioned in a compression state between mounting structures for elevator ropes and elevator machine components such that the compression member reacts and counters inwardly directed horizontal forces and resultant moment forces caused by a centralized, downward vertical load.
