Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator car operation panel, and particularly to a mechanism for opening and closing a face plate relative to a box.

[Prior art]

FIG. 1 is an exploded perspective view showing an example of a conventional elevator car operation panel. In the figure, 2 indicates a box, and although not shown, a push button switch for indicating a destination and a push button switch for opening/closing a door are housed in this box. 1 is a face plate that covers the opening of the box 2, and a large number of holes are formed on the surface at positions corresponding to the push button switches. An opening/closing mechanism 3 is provided which supports the face plate 1 on the box 2 so as to be openable and closable. This consists of a fixed hinge 4 fixed to the top and bottom of the back side of the face plate 1, a sliding hinge 5 rotatably fitted loosely to each fixed hinge 4 via a pin 4A, and the sliding hinge 5. A holder 6 is slidably held in the front-rear direction between the inner surface of the box 2, a long hole 6A on the holder 6 formed along the sliding direction, and a holder 6 is held between the holder 6 and the long hole 6A. It consists of a retaining pin 6B coupled to the sliding hinge 5. Note that the reference numeral 7 indicates a first fixing metal fitting formed on the back surface of the face plate 1, which is fitted and fixed between the inner surface of the left side wall plate of the box 2 and the second fixing metal fitting 8. It's summery. Reference numeral 9 indicates a hole provided in the face plate 1, and a position corresponding to a push button switch (not shown) for operating the door opening lock mechanism for maintenance and inspection provided in the box 2. The one shown with a sliding door covering the hole 9 is provided with a lockable key 11. 12 is a first fixing plate provided inside the hole 9, and this is a second fixing plate 13 installed inside the box 2.
and are fixed by screws 14.

In the elevator car operation panel described above, the face plate 1 can be opened and closed with respect to the box 2 by the fixed hinge 4 and the sliding hinge 5.
When closed, both the fixing metal fittings 7 and 8 are fitted and fixed, and both the fixing plates 12 and 13 are fixed with the screws 14, and then the sliding door lid 10 is closed and the key 11 is closed.
is applied. At the time of maintenance and inspection, the sliding door type lid 10 is opened using the key 11, contrary to the above description, and then the screw 14 is removed. Then, when the face plate 1 is pulled forward to release both the fixing metal fittings 7 and 8, the sliding hinge 5 is simultaneously pulled out and the fixed hinge 4 is rotationally displaced relative to the sliding hinge 5. . As a result, face plate 1 is box 2
It is slid forward and opened.

However, since a part of the sliding hinge 5 and the retaining pin 6B are exposed inside the box 2, when opening and closing the face plate 1,
When these slide and displace, there is a problem in that they interfere with the wiring inside the box 2, damage the insulation coating, and tend to cause short circuits.

[Summary of the idea]

The present invention has been made with the aim of improving such drawbacks, and by providing a cover on the box that covers the sliding part of the hinge mechanism located inside the box, the hinge mechanism can be moved when the face plate is opened or closed. The present invention proposes an elevator car operation panel that can prevent the sliding parts of the box from interfering with the wiring inside the box.

[Example of idea]

FIG. 2 is an exploded perspective view showing an embodiment of the present invention;
FIG. 3 is a plan view showing details of the hinge mechanism of the same embodiment. The same members as those shown in FIG. 1 are designated by the same reference numerals, and detailed explanation thereof will be omitted. The structure different from that shown in FIG.
It is 0. That is, this opening/closing mechanism 20 includes a hinge mechanism section 21 that supports the face plate 1 on the box 2 so as to be openable and closable and to be slidable in the front and rear directions.
and a cover 22 that covers the sliding portion of the hinge mechanism section 21 located inside the box 2.

For example, the hinge mechanism section 21 is rotatably connected to a first hinge plate 21A fixed to the upper and lower back side of the face plate 1 in two places, and is rotatably connected to the first hinge plate 21A. It is constituted by a second hinge plate 21C in which a guide groove 21B along the direction is formed. The cover 22 has a U-shaped cross section, covers the second hinge plate 21C so as to be slidably and loosely supported, and engages a fixture to be attached to the box 2, such as a fixing screw 22A, in the guide groove 21B. After fitting, it is attached to the box 2 by screwing it together using a nut 22B.

In the elevator car operating panel constructed in this manner, by pulling the face plate 1 toward the box 2 or pushing it backward, the face plate 1 is opened and closed relative to the box 2, and simultaneously moves back and forth. It will be slid in the direction.
When the face plate 1 is slid, the second hinge plate 2 is positioned within the box 2.
Since most of 1C is covered by the cover 22, the problem of unillustrated wiring inside the box 2 interfering with the second hinge plate 21C, damaging the insulation coating, and causing a short circuit is solved. can do.

In particular, the fixing screw 22A is used not only to attach the cover 22 to the box 2, but also to attach it to the guide groove 22.
Since it also has a function of preventing the hinge mechanism section 21 from falling off from the box 2 by engaging with B, it can contribute to a reduction in the number of parts and manufacturing costs.

It should be noted that the above embodiment is merely an example, and it goes without saying that various modifications can be made within the scope of the gist of the present invention. For example, the means for slidably holding one end of the hinge mechanism with respect to the box is not limited to using a cover as in the above embodiment, but the structure shown in FIG. 1 may also be adopted. can. Note that in this case, it is necessary to provide a cover over the holder 6.

[Effect of idea]

As detailed above, in the elevator car operation panel of the present invention, opening of the face plate,
This has excellent effects such as being able to prevent the sliding portion of the hinge mechanism from interfering with the wiring inside the box when the box is closed.
