摘要： A tension member termination device optimized for terminating flat tension members having compressible outer coatings, the device including a wedge and a socket each having cooperating surfaces positioned at a predetermined angle for clamping the tension member therebetween. The angle reliably secures the tension member while avoiding deleterious pressure and stress upon the tension member. The invention also provides a safety clamp for optional use with the tension member termination device.

摘要： 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.

摘要： An elevator machine having an outer wall, a rotatable output shaft with a sheave mounted thereon and a brake assembly for braking the output shaft and sheave. The brake assembly has a base integrally formed with the outer wall adjacent the output shaft. A metal base of the brake assembly is cast or embedded within the outer wall. Alternately, the outer wall forms the base of the brake assembly, The integrally formed base has a groove for housing a magnetic coil of a disc brake assembly. The base also has a plurality of bores for housing the brake springs and a plurality of bores for bolting the disc subassembly to the base. The disk brake assembly is fabricated by casting or imbedding a metallic blank of higher magnetic permeability into the casting of the outer wall to form the base thereof. A bearing assembly counterbore is machined into the outer wall and, without unsecuring the wall segment from the machining operation, the base of the disc brake assembly is machined to form the groove for housing a magnetic coil, a plurality of bores to house the brake springs and a plurality of bolt bores.

摘要： An elevator car includes a car frame and a platform assembly having a composite platform and a support frame. The composite platform includes upper and lower metallic sheets with a oriented strand wood layer therebetween and bonded to the sheets. The support frame includes a perimeter structure and a pair of centrally located stringers. The composite platform is rigidly attached about its outer edges to the perimeter structure and extends unsupported between the centrally located stringers and the perimeter structure. In a particular embodiment, the elevator car includes a door frame extending from the car frame and platform assembly and which is isolated from the cab of the elevator car.

摘要： An elevator car speed governor is mounted on the top of the car assembly, and measures car speed by contacting a fixed element in the hoistway. The fixed element can be a taut cable extending from the top of the hoistway to the pit, or one of the car guide rails, for example. The governor has a centrifugally operated connection with emergency brakes on the car. When overspeed is detected, the connection is actuated to cause the brakes to engage the guide rails and stop the car. The governor can operate at relatively low overspeed rates, and can be used on elevator systems which do not have an overhead machine room, such as hydraulic and linear induction motor elevators.

摘要： An elevator cab is constructed of a thin, somewhat semirigid skeleton. Expanded core plastic panels are attached to the skeleton, thereby forming a very light and rigid cab. These panels are attached by means of releasable hook-like fasteners, thus permitting selective removal of the panels from the skeleton. Due to strategic location of the fasteners on the skeleton, the panels, when attached to the skeleton, create a rigid cab.
