Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an anti-theft device for an elevator operation panel, which prevents the cover of an operation panel provided in an elevator car or a hall from being stolen.

[0002]

[Prior art]

 Conventionally, an operator panel for registering a car call in a car or an operator panel for registering a hall call simply fixes the insertion metal fittings provided on the back side of the cover of the operator panel with a restraining spring. . As a result, this cover can be easily removed, and this often causes the problem of the cover being stolen.

Therefore, as an antitheft device for a driving panel, for example, there is one disclosed in Japanese Patent Laid-Open No. 62-100382. In this anti-theft device, a rod body for pressing the lever of the micro switch is attached to the back surface of the cover of the driver's panel. When the cover is removed, the rod comes off the lever and the alarm sounds.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, the rod body for pressing the lever of the microswitch has to be attached to the cover, but since this rod body has to be attached in the direction perpendicular to the cover, it is very troublesome and costly. Further, since the rod body and the lever are pressed by the combined work, there is a problem that the work takes a long time.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide an antitheft device for an elevator operation panel which is easy to install and inexpensive.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a switch is provided at the bottom of the driver's panel box, and when the cover of the driver's panel box is removed, the elevator driver's panel is equipped with ringing means for operating the switch to ring an alarm. In the antitheft device, a metal fitting is provided on the back surface of the cover, and the metal fitting and the lever of the switch are connected by a string.

[0007]

[Action]

 Now, if an inexperienced person tries to steal the cover of the driver's panel and removes this cover, the lever of the switch is pulled by the cord, and the alarm device sounds and an alarm can be issued.

Further, according to this configuration, since the lever is configured to be operated by the cord body, the attachment can be made simple and the cost can be reduced.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 3 is a front view of the hall on the first floor. In the figure, 8 is a door, 9 is an indicator provided on the upper part of the door 8, and 10 is a hall call button device provided on the side wall of the door 8, which is also referred to as a hall operation panel here.

FIG. 1 is a cross-sectional view of a hall call button device to which the anti-theft device for a driving panel according to the present invention is applied. In the figure, reference numeral 1 is a cover of a driver's panel, 11 is a push button attached to the cover 1, and 2 are fittings provided at both ends of the cover 1, which are screwed to the cover by screws 3. Reference numeral 4 denotes an operator panel box, which is fitted into a wall 5, and a holding spring 6 is screwed to the operator panel box 4 by screws 7 at upper and lower positions of the operator panel box 4. Then, when the cover 1 is inserted into the driver's panel box 4, the presser spring 6 presses the insertion metal fitting 2 and the cover 1 is fixed to the driver's panel box 4. Reference numerals 20, 30, and 31 are switches, alarms and batteries attached to the bottom of the operation panel box 4, 21 is a lever for activating the switch 20, and when activated, the switch 20 is self-held and a reset button (not shown) is used. It will be canceled. Reference numeral 22 is a metal fitting, which is screwed to the cover 1 by a screw 23, the metal fitting 22 and the lever are connected by a cord 24, and when the cover 1 is pulled out, the cord 24 is pulled and the lever 21 is operated. .

FIG. 2 is an electrical connection diagram of the anti-theft device according to the present invention, in which 20a is a normally open contact of the switch 20, 32b is a normally closed contact of a relay (not shown) which is energized during maintenance operation, and is connected in series with the battery. The contact 20a, the contact 32b, and the alarm device 30 are connected to.

Next, the operation of this embodiment will be described.

Now, assume that an unskilled person tries to steal the cover 1 and pulls out the cover 1. Along with this, the cord 24 is pulled, and when the cord 24 is tensioned, the lever 21 operates and the contact 20a is closed and locked. At this time, since the contact 32b is closed, the alarm device 30 sounds and issues an alarm to prevent the cover from being stolen. The administrator can reset the switch 20 by hearing the alarm sound and restore the original state.

As described above, the present antitheft device has a structure in which the lever 21 of the switch and the metal fitting 22 attached to the cover 1 are simply connected by the cord 24, so that an easy-to-install and inexpensive device is provided. Can be provided.

Although the cord 24 is connected to the metal fitting 22 in the above embodiment, it is not always necessary to connect the metal fitting 22 to the metal fitting 22, and the same effect can be obtained by fixing the cord 24 to the screw 3.

Further, although the above-described embodiment has been described with respect to the cover of the landing button, the same can be applied to the driving panel for registering the car call in the car.

[0018]

[Effect of device]

 As described above, according to the present invention, the switch lever has a simple structure in which it is connected to the metal fitting provided on the back surface of the cover with a cord, so that the installation work is easy and the cost is low. A prevention device can be provided.
