The present invention relates to a switchgear and a switchgear having its operating device, and more particularly to a switchgear configured to be capable of relative movement that requires accurate positioning for a suitable opening and closing operation.

In some types of applications of the electric switchgear, it is necessary to operate the switch to direct the positional relationship of the animal to the animal relative to the stationary object. Therefore, the switch and the operating device are installed to be relative to the movement, the switch or the operating device is carried by the animal body. Other related instruments are installed on the fixture.

A typical use of such switchgear is to detect the position of the elevator car in the hoistway in an elevator device. The elevator system needs this location information to properly control the operation of the car or cars. Examples of such switchgear include (a) a device for generating light beams blocked by the actuating device, (b) a mechanical switch with a cam follower operated by the cam actuating device, and (c) a vane or plate of magnetic material. There is an inductive relay type magnetic switch with an incomplete magnetic circuit completed by a type of actuator, and the magnetic circuit for operating the switch is completed by close proximity of the magnetic switch and the vane, and (d) a permanent magnet actuator. Magnetic switch such as a reed switch that is operated from one position to another position by means of magnetic field. All these devices require precise positioning and alignment of the various elements for proper operation, especially when the switchgear is operated through a flat nonmagnetic cover by means of a flat magnetic plate actuator. Shall be. In this case, the two flat surfaces need to be precisely adjusted for the distance and angle. Thus, this adjustment between the switchgear installed in such a normal elevator car and the magnetic vane installed in the hoistway is very tedious and time consuming.

The main object of the present invention is to provide a switchgear capable of quickly and accurately adjusting the relative position between the electric switchgear and the operating autonomous.

According to this object, the present invention has a first end and a second end in an opening and closing device having an electric switch and its operating device, a spherical ball part at the first end, a screw part starting at the second eye part and the A first rod member having an axial opening extending between both ends and a threaded portion of the first rod member with screws to allow selection of a desired position of the first rod member and to fix the selected position A first access opening of the housing part, having a mounting device including a nut, a housing part defining a groove part having at least first and second access openings, and an adjustable part mounted to pivot along a spherical surface of the spherical bowl part; Is in communication with the axial opening of the first rod member, wherein the adjustable portion is a selected angular position of the pivot on the spherical bowl.

And the switch is operated in response to a predetermined positioning relationship with respect to the actuating device.

Now, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

In summary, the present invention represents an improved switchgear suitable for use that allows the switchgear and actuator to be installed in a relative motion. The switchgear includes a mounting device capable of linear adjustment and angle adjustment, the mounting device forming a completely closed wiring duct for the switch lead. This adjustment can be made without twisting the electrical wiring since linear adjustment and angle adjustment do not require rotation of the switch or parts associated with the housing.

The actuator is equipped with a mounting device for linear and angle adjustment. When the actuator is in the form of a flat vane with a plane, the linear adjustment and the angle adjustment are both made through the access opening provided in the actuator, which can easily be made from the elevator car when the actuator is installed in the elevator hoistway.
