Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push button box which can be easily attached to the inside of a panel separating an elevator hall and a hoistway from the outside of the panel.

[0002]

2. Description of the Related Art For example, when a push button for a wheelchair is mounted on a unit type elevator landing, in a conventional mounting method, a push button is mounted on a panel separating an elevator landing (hereinafter referred to as a landing) from a hoistway. After the opening is provided, the push button box is welded to one side of the L-shaped fitting for mounting the push button box in the vertical direction of the opening from the hoistway side to the panel, and the push button box is welded to the other side. Was attached to the back of the panel.

Next, a conventional push button box attached to the back of the panel will be described with reference to the accompanying drawings. FIG. 14 is a vertical sectional view of a conventional push button box. In the figure, reference numeral 9 denotes a panel that separates the landing from the hoistway, and in fact, as shown in FIG. 16, a panel 9 that separates the landing 12 from the intermediate beam 15 provided between the adjacent elevators 13 and 14 in the hoistway 11.

[0006] Reference numeral 6 denotes an L-shaped push button mounting bracket welded from the hoistway 11 side to the vertical direction of a rectangular opening 10 cut out from the panel 9 as shown in FIG. The front of the push button box 2 is the opening 1 of the panel 9.
It is welded in a state of being sandwiched between a pair of push button mounting metal pieces 6 toward zero. Reference numeral 3 denotes a push button plate mounting metal (hereinafter, referred to as a plate mounting metal) fixed by a push button plate mounting metal fixing nut (hereinafter, referred to as a fixing nut) 8 to each of an upper surface and a bottom surface inside the push button box 2. The plate mounting metal 3 is formed by bending a part of the front end surface into an L shape with a predetermined width from the center as shown in FIG. A special nut 5 is inserted through a hole 7a having a diameter of about 5 mm through which a mounting screw (hereinafter, referred to as a plate mounting screw) 7 is passed, and the hole 7a is aligned with the nut portion.
Is attached to it. On the back of the push button plate 1,
A push button unit 4 having a button cover exposed on the surface is fixed.

[0005] Next, a method of mounting a conventional push button box will be described. When attaching the push button box, the operator cuts out the rectangular opening 10 shown in FIG. 15 from the hall 12 side to the panel 9, and then welds the push button mounting metal 6 to the top and bottom surfaces of the push button box 2. A push button plate mounting metal fixing screw (hereinafter, referred to as a fixing screw) 8a protrudes from an upper surface and a bottom surface inside the push button box 2, and the fixing screw 8a is provided in the plate mounting metal 3 in a screw hole. , And tightened with a push button plate mounting metal fixing nut (hereinafter, referred to as a fixing nut) 8, so that the plate mounting metal 3 is mounted on the push button box 2.

[0006] When the respective push-button mounting brackets 6 are welded to the push-button box 2, the operator gets on the basket of the work elevator 14 shown in FIG. 16 and opens the push-button box 2 from the hoistway 11 side. The surface is pressed against the opening 10 and the push button mounting metal 6 is welded to the panel 9. At the time of welding work, a fire prevention sheet is cured around the work space 17 shown in FIG. 16 to prevent fire.

When the welding of the push button box 2 is completed, the worker again goes to the landing and applies the push button plate 1 having the push button portion 4 attached to the opening 10, and through the holes provided above and below the push button plate 1, The plate mounting screw 7 is fastened to the service nut 5 mounted on the bent portion 3a of the plate mounting metal 3. As a result, the push button plate 1 is screwed to the push button box 2 with the panel 9 interposed therebetween.

[0008]

In the conventional push button box, the worker has to mount the box by reciprocating between the hoistway and the landing because of the structure thereof. Doing so has a problem in that the work space is small, so that mounting work becomes difficult and time is required.

[0009] There is a problem in that the work area is hardened by a disaster prevention sheet for fire prevention during welding work, so that it takes time and effort to set up the work.

[0010] Furthermore, since the operator is forced to work by leaning the body on the intermediate beam from the basket of the working elevator, there is a problem that the workability is extremely poor. Also,
Regarding the intermediate beam, there is a case where the beam for mounting the intermediate beam enters along the hoistway on the landing side of the hoistway depending on the site, so that work from the hoistway may not be possible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides a push-button box in which a housing for accommodating a push-button can be mounted from a landing and without fire. The purpose is to:

[0012]

According to a first aspect of the present invention, there is provided a push button box, wherein a tip portion is bent into an L-shape on each of a pair of opposing surfaces of a housing for housing the push button, and screws are screwed. Attach the mounting plate formed by providing the part with the bent part forward,
The case is inserted from the opening formed in the front surface of the panel to the back surface, and a screw is passed through the screw portion of the bent portion from a hole formed in the front surface of the panel, and the case is screwed to the panel. A push button box characterized by the following.
