Abstract: The invention relates to a push button panel for an elevator. The push button panel includes a front panel and push button areas provided on the front surface of the front panel. The front panel is made of a material having a high degree of rigidity. At least in the regions of the push button areas, the back surface of the front panel is provided with elements sensitive to pressure changes. The sensor element is connected by at least one signal conductor to the data transmission system of the elevator. The sensor element preferably consists of a film which, when subjected to mechanical work, produces an electric signal.

Abstract: The invention relates to a compensation system in an elevator comprising an elevator car (2), a counterweight (3), a set of elevator suspension ropes (11) on which the elevator car (2) and the counterweight (3) are suspended, a traction sheave (5) whose motion is transmitted via the suspension ropes (11) to the elevator car (2) and to the counterweight (3), and a set of compensating ropes (4) and at least one diverting pulley (15) belonging to the suspension rope system (11) and at least one buffer arrangement (9) for the counterweight (3). The suspension ratio of the compensating rope (4) is the same as that of the suspension ropes (11), or multiplied by a coefficient. The rope suspension ratio on the side of the elevator car (2) is the same as or different than on the side of the counterweight (3). For the compensation of the elongation of the suspension and compensating ropes (11 and 4) of the elevator, a buffer (23) below the counterweight (3) has a provision for vertical adjustment.

Abstract: Guide seat for an elevator car, which supports a guide moving along a guide rail (6). The guide seat comprises a fixing part by which the guide seat is attached to the car structure (2), and a base plate (12,26,33) on which a guide structure is mounted. To pass the forces between the guide rail (6) and the elevator car (1), the guide seat is provided with at least one insulator (17,30,32) made of an elastic material, such as rubber. The insulator is placed between the fixing part and the base plate.

Abstract: A safety gear e.g. for an elevator car or counterweight, comprises at least one wedge chamber (8) and at least one working wedge (9) acting on an elevator guide rail (30) and activated by a transmission element. For each working wedge (9), the safety gear has at least one counter wedge (10) moving along guide surfaces (14 and 39) provided in the wedge chamber (8). The counter wedge (10) of a working wedge (9) is on the same side of the guide rail as the working wedge (9) in question.

Abstract: Traction sheave elevator has a drive machine (1) and, coupled with it, a traction sheave (3) provided with a rope groove (2), the hoisting rope (4) running over the traction sheave, an elevator car (6) and its counterweight (7) suspended on the hoisting rope and moving in an elevator shaft (6). The elevator uses at least two diverting pulleys (8,9) which causes the hoisting rope going to the traction sheave (3) and the hoisting rope coming from the traction sheave (3) to run crosswise with respect to each other. The diverting pulleys and the traction sheave are placed so that the planes of rotation of the diverting pulleys (8,9) lie on different sides of the plane of rotation of the traction sheave (3).

Abstract: A toe guard for an elevator is disclosed, at least part of which consists of a structure penetrable to air flow, thus diminishing the tendency of the toe guard to increase the air flow in the space between the front wall of the elevator car and the shaft wall.

Abstract: A safety gear for an elevator, in which the safety gear housing is mounted on the frame using transverse bars or the like. To prevent accidental gripping of the wedges when the elevator car moves laterally, the safety gear housing is allowed to move laterally along the bars. The safety gear is provided with guiding means placed on either side of the guide rail so that the clearance between them and the guide rail is smaller than the clearance between the wedge and the guide rail. Thus, when the lateral displacements of the frame of the elevator car relative to the guide rail exceeds the distance between the guiding means and the guide rail, the safety gear housing is moved laterally and a minimum distance between the wedge and the guide rail is maintained, said minimum distance being at least equal to the difference between said clearances.

Abstract: An arrester device, e.g. for an elevator cage or counterweight, has a wedge housing, an active wedge acting on one side of an elevator guide and activated by a separate transmission member, such as a rope, and a counterwedge acting on the elevator guide from the opposite side. The movements of the wedge and the counter wedge are directed to pass along inclined guide surfaces, the distance between the top margins of the guide surfaces being equal to or larger than the distance between their lower margins. The angle of inclination of the guide surfaces equals the wedge angles of the wedge and the counterwedge, respectively. Furthermore, the wedge housing comprises a force member, such as a spring, which exerts on the counterwedge a force substantially parallel to the respective guide surface.

Abstract: A torque-responsive brake, in particular for elevators, comprises two or more brakes arcs, brake shoes pivotally connected to the brake arcs and having attached brake linings and a brake actuating mechanism for pressing the brake linings against a drum. With prior art brakes, the starting of the elevator was not smooth enough or, alternatively, the types of apparatus by which smooth starting has been achieved were too complicated and expensive. By the present invention these drawbacks have been overcome in that, for pivotally attaching each brake shoe to its brake arc, a pivot shaft extends through the respective brake shoe and is connected to one end of a torque-responsive member, the opposite end of which is fixed to the respective brake arc.

Abstract: A traction sheave in particular for a lift moving machinery, by which the torque is transmitted from the machinery shaft to the ropes supporting the lift cage. The problem in lift traction sheaves of prior art with rigid construction is their objectionably strong tangential vibration, due to the machinery. In the invention this problem has been solved in that the outer rim of the traction sheave is connected to a flange on a hub by the aid of at least one elastic element, and that the outer rim is rotatably carried on the hub.
