Description

A combination structure of position indicator box for an elevator}

The present invention relates to a coupling structure of an elevator locator box installed in the doorway of the elevator and the cage for the elevator, and more particularly, to protrude an insertion port having a ball-shaped head on a base plate installed on the wall of the elevator. In addition, by installing a spring-type elastic fastener into which the insertion hole is elastically inserted in the front cover installed in front of the base plate, the base plate and the front cover can be easily and firmly coupled to the base plate and the front surface. It relates to a coupling structure of the position indicator box for an elevator to allow the overall thickness of the cover is thin.

In general, the elevator locator is installed at the doorway and the elevator cage of the elevator to allow the occupant to check the exact position of the elevator cage, and to open and close or move the call button and door to call the staff when the elevator malfunctions. Each pushbutton, such as an operation button for selecting a floor, is installed to call the staff and move the elevator cage to the desired position.

The position indicator for an elevator used as described above includes a base plate fixed to an entrance of an elevator and a wall of an elevator cage, and a front cover coupled to a front surface of the base plate. The coupling type of the front cover includes a general type of coupling using a screw, and there is a type in which the coupling is press-fitted as shown in FIGS. 1 and 2. In the former case, the head of the screw is moved out of the front cover.

Hereinafter, the present invention for achieving the above object will be described in detail with reference to FIGS. 3 and 4.

The coupling structure of the position indicator box for an elevator according to the present invention, as shown in Figure 3, the position display window (5) and the front of the base plate (1) which is fixed to the wall of the door and the elevator cage of the elevator and The front cover 4, which is installed with the push button, is applied to the coupling by the coupling means.

In order to fix the base plate 1 to the entrance of the elevator and the wall of the cage for the elevator, the upper and lower parts of the base plate 1 have a long horizontal screw insertion hole 7 and a vertically long screw insertion hole 7. ) Is penetrated, and a head portion 9 is formed at the front end of the base plate 1 in the form of a ball at the front end thereof, and an outer diameter thereof is reduced at the rear end coupled to the base plate 1. The insertion opening 10 provided with the neck part 8 is fixedly installed so that it may protrude forward.

In addition, a pair of screw rods 11 are welded to the front cover 4 to protrude rearwards on both upper and lower inner surfaces of the front cover 4, and 5 to 10 mm on each of the screw rods 11. An insertion tube 12 having a size is installed to be inserted into the outer side of the screw rod 11, and thus elastically supporting the insertion hole 10 in a state in which the insertion tube 12 is inserted into each screw rod 11 as described above. The fastener 13 is inserted into the upper surface of the insertion tube 12 through both of the threaded rods 11. The elastic fixture 13 has a ring-shaped screw through portion through which the threaded rod 11 is inserted into both sides. (14) is formed, the center portion corresponding between the two threaded through portion 14, the insertion hole insertion portion 15 of the ring shape is inserted into the head portion 9 of the insertion hole 10 having a ball shape elastically It is formed, the elastic fastener 13 is fixed to the front end of each of the screw rod 11, the elastic fastener 13 is inserted It is entered into the nut 16.

The elastic fixture 13 may be formed by bending a wire having elasticity or may be formed by pressing a metal plate having elasticity. At this time, both the screw through portion 14 formed in the elastic fastener 13 and the insertion hole insertion portion 15 of the center formed between the two screw through portion is in communication with each other the head portion 9 of the insertion hole 10 When is inserted elastically when the insertion of the head (9) is completed, it should be retracted elastically.

The working relationship of the present invention having the above configuration will now be described in detail with reference to FIGS. 3 and 4.

In order to install the elevator locator box, the base plate 1 must be installed at the entrance and the wall of the elevator cage in which the elevator locator box will be installed. In this case, the base plate 1 is placed in the horizontal direction at the top and the bottom of the base plate 1. Thus, it is installed as a screw using the long screw insertion hole 7 and the long screw insertion hole 7 in the vertical direction. Each of the screw insertion holes 7 is formed in the shape of a long hole so that the base plate 1 can be easily installed even when the screw installation position is slightly shifted.

After the base plate 1 is installed as described above, the front cover 4 having the elastic fasteners 13 installed above and below the inner side is press-fitted from the front of the base plate 1, and the front cover 4 Since the elastic fastener 13 installed in the above is installed so as to face each other with the insertion hole 10 installed in the base plate 1, the front cover 4 with a slight force in the state facing the base plate 1 When the front cover 4 is pushed in, the head 9 of the insertion hole 10 is inserted into the insertion hole insertion portion 15 of the elastic fixing tool 13 so that the front cover 4 is placed in front of the base plate 1. It will be easy to combine.

As such, the principle that the elastic stopper 13 of the front cover 4 and the insertion hole 10 of the base plate 1 are coupled to each other and supported is an insertion hole inserting portion 15 of the elastic stopper 13 having a predetermined elasticity. When the head 9 of the insertion hole 10 formed in a ball shape is inserted, the insertion hole insertion part 15 is opened by the force pushing the head 9, and the head 9 is inserted first. Since the outer diameter of the neck 8 behind the head 9 is smaller than that of the head 9, the insertion of the head 9 is completed and at the same time, the insertion hole insertion part 15 is retracted by its elastic force. As a result, the insertion hole inserting portion 15 of the elastic fastener 13 is in a state of biting and supporting the neck portion 8 behind the head 9, so that the insertion hole 10 is not separated from the elastic fastener 13. Even if the front cover 4 is firmly coupled to the front of the base plate (1).

As such, the present invention allows the insertion port 10 and the elastic fixing tool 13 formed in the form of a ball to be easily coupled so that the front cover 4 can be easily coupled to the front of the base plate 1 without a separate tool.

In addition, as shown in Figure 4, while supporting both ends of the elastic fixture 13, the insertion tube 12 to maintain a predetermined distance from the front cover 2 can be manufactured as small as about 5 to 10mm Since the overall height (thickness) combined with the plate 1 and the front cover 4 can be lowered, it is possible to provide an elevator locator box with a beautiful appearance. It should be manufactured as small as about 10mm in size, but in industrial case, it can be made as large as about 10 ~ 20mm.

In the description of the present invention, the description of the components such as the position display window 5, the push button pressed to call the elevator and move to the desired position, and the push button switch have been omitted, but these parts are the elevator of the present invention. Note that it is embedded within the locator box.

As described above, the coupling structure of the elevator position indicator box according to the present invention is provided so that an insertion hole having a ball-shaped head is protruded from the base plate fixed to the door of the elevator and the wall of the elevator cage, and the front of the base plate. By installing the spring-type elastic fixture in which the insertion hole is resiliently inserted into the inner side of the front cover to be installed in, the effect of making the base plate and the front cover simple and firm, and the base plate and the front cover are combined By reducing the overall thickness is an effect that can provide an elevator placeholder box with a beautiful appearance.
