Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car switch box.

[0002]

2. Description of the Related Art A conventional car top switch box in an elevator is a box type having an opening / closing cover on the front side and is attached to a crosshead. In the switch box, a car raising switch button, a car lowering switch button, a switch for switching between valid and invalid of these switch buttons, a stop switch for preventing the car from running no matter which switch is pressed, and An outlet and the like are stored, and the operation surface of each switch button and each switch is vertical.

[0003]

The above switch box is suitable for preventing water from entering, but it is necessary to open the cover when operating the switch button or the switch for moving the car during maintenance and inspection. Yes, it is annoying. Also,
If you forget to close the cover, the function to prevent water from entering the switch box will be lost. An object of the present invention is to provide a car-top switch box for an elevator, which can prevent opening and closing of a cover before and after using a switch button or the like and can prevent water from entering.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a switch box containing a car raising switch button, a lowering switch button, a switch for enabling / disabling a raising switch button and a lowering switch button, and the like. In an elevator car switch box attached to a crosshead on a car, the switchbox is formed into a box shape having one open surface, and the switchbox is crossheaded so that the open surface faces downward. It is achieved by mounting the switch button and the switch so that the operation surface thereof faces downward.

[0005]

With the above structure, when operating the switch button or the like, if the operator puts his / her hand on the open surface from below the switch box, the oil reaches the operation surface of the switch button or the like.
It is possible to operate switch buttons and the like. Further, the upper surface of the switch button and the like and the sides in four directions are surrounded, and the crosshead faces the open surface, so that water droplets splashing from above or obliquely above do not directly hit the switch button or the like. , Can prevent the invasion of water.

[0006]

EXAMPLES Examples of the present invention will be described below with reference to FIGS. In the drawing, 1 is a car, 2 is a crosshead fixed to the side surface of the car 1, and is composed of a pair of vertical frames 2A and a horizontal frame 2B connected to the upper ends of both vertical frames 2A. A main rope having a section attached thereto, 4 a switch box attached to a horizontal frame 2B of the crosshead 2, 5-9
Is a switch button, switches and outlets housed in the switch box 4, 5 is a car raising switch button, 6 is a car lowering switch button, and 7 is a switch for switching between valid and invalid of the switch buttons 5 and 6 , 8 is a stop switch for preventing the car 1 from running even if the switch buttons 5, 6 and other switches, for example, the switch buttons 5, 6 and other switches are pressed, and 9 is an outlet ing. 10 is each switch button 5-9
Is a display sticker that displays the switch name of the switch box, and is stuck on the surface of the switch box 4. The switch box 4 has a box shape with one surface open.
It is fixed in the concave portion of the horizontal frame 2B having a U-shaped cross section so that the open surface faces downward. Then, a sufficient gap is formed between the lower surface of the switch box 4 and the portion of the horizontal frame 2B designated by the reference numeral 2B1 so that a hand can be inserted. The switch buttons 5 to 9 are arranged and fixed in the switch box 4 such that the operation surface thereof faces downward. For maintenance, inspection, etc., switch 5 etc. for running the car 1
8 is operated under the switch box 4, operate the switch 7 with a finger to activate the switches 5 and 6, and then push the switch button 5 or the switch button 6 with the fingertip to raise the car 1. Or lower it.

As described above, since the switch box 4 is box-shaped and the open surface is downward, water droplets splashing from above or obliquely above hardly enter the switch box 4 and it is possible to eliminate the cover. . Therefore, it is not necessary to open the cover before and after using the switches 5 to 8 and the outlet 9, and no harmful effect due to forgetting to close the cover cannot occur.

[0008]

As described above, according to the present invention, there is provided a switch box for a car in an elevator which can prevent the invasion of water while eliminating the need to open the cover before and after using the switch button or the like. can do.
