Abstract: Disclosed is an emergency stop device with an attached hand brake system. The emergency stop device with the attached hand brake system comprises: brake units which are equipped on both sides of a car and control the movements of the car by selectively interfering with guide rails; an operation unit which is connected with the brake units and manually grants braking power to the braking units; and an interlocking unit which interlocks the brake units.

Abstract: An elevator may include an elevator car, one or more hoisting ropes, a traction sheave, an overspeed governor, at least one safety gear, a locking mechanism, and guide rails. The car may be suspended by the one or more hoisting ropes. The traction sheave may move the car using the one or more hoisting ropes. The at least one safety gear and locking mechanism may be fitted in conjunction with the car. The overspeed governor may be configured to activate and release, via a linkage, the at least one safety gear during operation of the elevator. The locking mechanism may be configured to activate and release, by operatively acting on the linkage, the at least one safety gear during installation, maintenance, or installation and maintenance of the elevator. When activated, the at least one safety gear may engage one of the guide rails to lock the car in place.

Abstract: An assembly (30) controls the amount of downward movement of a counterweight (24) within an elevator system (20). By limiting the downward movement of the counterweight (24), a desired overhead clearance above an elevator car (22) can be maintained. One example includes at least one safety device (80, 84, 86, 88) on top of the elevator car (22) to provide an indication for when a holding member (34) should allow a stop member of the assembly (30) to move into a position to limit the downward movement of the counterweight (24). In one example, the stop member (32) moves into an employed position by the force of gravity and is manually moveable back into a retracted position when it is not needed. One example includes a guide member (60) that facilitates controlling the position of the stop member (32) when it is in the employed position.

Abstract: A portable elevator climbing system removably attachable to a cantilevered overhang on an adjacent structure, whereby an elevator car travels up and down a plurality of roller chains. The roller chains are engaged with sprockets and guide rollers attached to an axle driven by a motor. The orientation and alignment of the sprockets, guide rollers and roller chains provide for a stable elevator car and for a system free of backlash in both directions. The elevator climbing system includes a dampening assembly to control the rate of decent in the event of transmission, motor or other failure. The elevator climbing system may be controlled so that the start and stop of the motor is coordinated with the release and application of a braking assembly. The efficiency of the elevator climbing system may be varied by adjusting the offset between the sprockets and the guide rollers.

Abstract: A method for creating a temporary safety space within an elevator hoistway by preventing upward or downward movement of a car or counterweight along guide rails. The method includes the steps of providing engagement members on the guide rails and extending support struts from the car or counterweight to either side of a guide blade of the guide rail, whereby upward or downward movement of the car or counterweight along the guide rail is prevented when the extended support struts bear against the engagement members.

Abstract: An elevator escape arrangement includes a hinged window on a car; an escape rope passed by the window; a spring biased linking mechanism interconnected the window and a door; and a drive assembly including a first shaft, a detent block on the first shaft and between two brake bars, a cam-like member engaged with a drive sheave, a pulley on the first shaft with the escape rope run, a first gear on the first shaft, a second gear meshed with the first gear, and a second shaft passed through the second gear and the cam-like member. In case of emergency with the car stuck between two floors, the car and a counterweight balanced, and the brake activated, opening the window will cause the linking mechanism to lock the door, pulling the escape rope will unbalance and move the car, and closing the window will unlock the door for escape therethrough.

Abstract: A load stopping system for mechanically stopping a load in a relatively slow and controlled manner using rotational and frictional forces. The system includes a glide rod, a guide collar that moves longitudinally over the glide rod, two vertically mounted friction rods mounted on opposite sides of the glide rod, a friction collar that moves longitudinally along each friction rod, and a support platform coupled to each friction collar and to the guide collar. The glide rod includes a spiral fluted vane along its entire length upon which the guide collar rides when a force is placed on the support platform. The friction rod and collars use friction to control the movement of the support platform along the direction of travel.

Abstract: A brake assembly for an in-vehicle platform lift including at least one column and at least one flexible drive member. The brake assembly has at least one lever including a brake face that engages the column to brake the platform lift when the flexible drive member goes slack. The brake assembly is biased into the brake position and can be configured to brake the platform lift when the flexible drive member is stationary.

Abstract: The invention provides an elevator having a car movable along guide rails mounted in a shaft. The elevator comprises an inspection control station mounted on top of the car and accessible via a movable control station cover, blocking means for selectively preventing movement of the car into a safety space within the shaft and actuation means for actuating the blocking means. The actuation means is configured for concurrent movement with the control station cover. Accordingly, a temporary safety space is automatically created within the shaft as the maintenance technician opens the control station cover to move the car using the inspection control station.

Abstract: Backup power device for an elevator comprises a brake including a brake controller and a manual brake rod, a damping assembly including a roller at one end of a lever, and a wheel having alternate recesses and risers, an electro-magnetic controller having a control rod, a pulley having a rope run through the manual brake rod and the control rod, an electro-magnetic brake actuator, and a backup power supply. A passenger trapped in the car can pull down the rope in case of the failure of the electro-magnetic controller, the electro-magnetic brake actuator, and the backup power supply as the lever turns to cause the roller to contact the recess or the riser. The lever moves intermittently to cause the manual brake rod to activate the brake controller for braking and releasing a motor shaft again in intervals. Eventually, the passenger can escape.

Abstract: An auxiliary device for displacing a payload receptacle, which stands outside a station, into one of the stations. The auxiliary device includes a temporarily activatable brake release device for releasing the braking device and an auxiliary drive device for displacing the payload receptacle when the brake release device is activated. The brake release device and the auxiliary drive device are arranged in the uppermost region of the elevator shaft and are actuable by way of a crank rod linkage. The crank rod linkage includes a lower actuating end, which can be brought from a rest setting into a working setting. The crank rod linkage is coupled with a rod linkage extension, the vertical effective length of which corresponds with at least the vertical spacing of the walk areas of two adjacent stations.

Abstract: A manual brake release control structure having a linking member cooperates with an escape and protection mechanism for an elevator to protect an emergently braked elevator cab against inertial slip during brake release. By pulling an escape pulling cable outside the cab with a normal force, the braked cab is released to move and rotate a rotary shaft of a driving motor of the elevator. The rotary shaft in rotating causes a cam connected thereto to rotate and thereby reciprocates the linking member up and down that in turn causes an actuating arm and a flexible long member to repeatedly release and depress a braking device of the elevator, so that the cab is intermittently braked and released to move upward or downward at a reduced safety speed.
