    • A brake mechanism (10) for an elevator (2) is activated in response to an electronic control signal to prevent movement of an elevator car (16) under predetermined conditions. The brake mechanism is preferably a safety mechanism (10) and does not require a governor sheave, a governor rope, or a tension sheave. The safety mechanism in one disclosed example utilizes a solenoid actuator (22b) and an electric motor (40) and gear box assembly (42) to move safety wedges (18) into engagement with a guide rail (20) to stop the elevator car (16). The safety wedges (18) are held in a non-deployed position during normal elevator operation. If there is a power loss or if elevator car speed exceeds a predetermined threshold, an electronic control signal activates the safety mechanism (10) causing the solenoid to release, which causes the safety wedges (18) move in a direction opposite to that of a safety housing (12) mounted for movement with the elevator car (16). Angled surfaces of the safety housing (12) force the safety wedges (18) into engagement with the guide rail (20). The safety mechanism (10) can be selectively reset from a remote location.

    • An exemplary elevator braking device comprises a brake housing. A plurality of rollers are supported by the brake housing. The rollers are arranged to be positioned on opposite sides of a guiderail. The rollers are selectively moveable between a first position in which the rollers are spaced apart a first distance and a second position in which the rollers are spaced apart a second, smaller distance so that the rollers engage and roll along opposite sides of the guiderail. At least one biasing member is supported by the brake housing. The biasing member is associated with at least one of the rollers and biases the associated roller toward the other roller in the second position. A plurality of braking surfaces are supported by the brake housing. At least one braking surface is associated with each of the rollers. Each braking surface engages a periphery of the associated roller that faces the side of the guiderail. Friction between the periphery of the associated roller and the braking surface provides a stopping force.

    • An elevator safety based on having the elevator lift-rod, under the influence of the elevator governor, cause to rotate approximately elliptical cams, called quasi-elliptical cams. The cams are wider in one orientation, just as an ellipse has a major axis, wider than its minor axis. The cams are positioned to push against a brake pad as they rotate so that the major axis of each cam changes orientation with the minor axis. The cams can be shaped to simulate a wedge-type safety, even one using a wedge with multiple ramp angles. With essentially no additional complexity, the cam safety can be designed to operate with a bi-directional governor, one which exerts, usually through an intermediate linkage, force on the lift-rod in either the up or down motion depending on the unintended motion of the elevator.
    • 在电梯调速器的影响下,具有电梯升降杆的电梯安全系统使大致椭圆形的凸轮(称为准椭圆形凸轮)旋转。 凸轮在一个方向上较宽,就像椭圆具有比其短轴宽的长轴。 凸轮被定位成在它们旋转时推靠在制动衬块上,使得每个凸轮的长轴以短轴改变定向。 凸轮可以成形为模拟楔形安全性,甚至可以使用具有多个斜坡角的楔形件。 基本上没有额外的复杂性,凸轮安全性可以被设计成与双向调速器一起操作,双向调速器通常通过中间连杆在上升或下降运动中施加在升降杆上的力,这取决于非常意图的运动 电梯。

    • An overspeed governor comprises a pair of wedge brakes for selectively acting against a brake surface attached to the rotational shaft of an elevator drive. A maintaining apparatus is provided to maintain the wedge brakes in a normal position, out of engagement with the brake surface. A centrifugal actuating apparatus is also provided, attached to the rotational shaft of the elevator drive. If the rotational velocity of the elevator drive exceeds a predetermined limit, the centrifugal actuating apparatus displaces the maintaining apparatus, thereby allowing one of the wedge brakes to engage the brake surface.
