Embodiment Construction

[0020] figure 1 A safety device 1 representing the invention, made of a durable material such as steel, comprises plate-like stop means hinged by pivots 6 at the bottom of the shaft. Fitted on the upper end of the stopper is a crosspiece 5 provided with a support 8 for abutting against a safety buffer attached to the bottom side of the car unit 9 . Safety bumpers can also be installed on safety devices and their function is to dampen shocks. The car unit includes the car and the car frame or just the car. The safety device pivots about its pivot 6 between a normal position and an operative position. The safety device also includes a locking device 7, which locks the safety device 1 in the operating position. The locking device can be opened and closed manually. In addition to the locking means, the safety device also includes a fixing mechanism 20, such as a magnet, for fixing the safety device in the operating position. Magnets grip the elevator rails. The securing mech...

Abstract

Elevator safety dvice (1) for implementing a safety space, said elevator comprising an elevator shaft, a shaft bottom (10), a car unit (9), a counterweight (16), landing doors (11) , a space (14) defined by an outer edge (15) of the car unit and the corresponding wall (13) of the shaft, in which space the counterweight can be moved. The safety device (1) has been arranged on the bottom (10) of the shaft in the space defined by an outer edge of the car unit and the corresponding shaft wall so that it is not in the path of the counterweight and that, in an operation position, the safety device (1) can be brought into the path of the car unit (9).

Description

technical field [0001] The invention relates to an elevator safety device Background technique [0002] When elevators are installed in old buildings, it is often necessary to adopt technical solutions that take up as little space as possible. If the space at the top or bottom of the elevator shaft is to be enlarged, the construction is often either impossible for structural reasons or expensive to carry out. Also, safety spaces required by safety regulations for maintenance purposes must be provided above and below the car. [0003] According to Finnish application 980594, in order to ensure the required safety space, it is known to provide a safety buffer structure at the bottom of the elevator shaft for maintenance purposes. Safety buffers according to this application can be arranged on the path of the elevator car in order to prevent the car from moving downwards beyond a certain distance from the bottom of the shaft and likewise under the counterweight to prevent the...
