Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator operation panel, and more particularly to an elevator operation panel with improved attachment of a cover constituting the operation panel.

Generally, as shown in FIGS. 1 and 2, an elevator operation panel is constructed by fixing a case 3 having an opening in the front to a side wall 4 of an elevator structure, for example, a corner, and attaching a cover 1 that closes the opening. It is normally attached to the case 3 with fixing screws 2.

Various button parts and display parts are arranged to face the surface of the cover 1, and an operating device is installed between the cover 1 and the case 3.

Furthermore, the case 3 and the cover 1 are long in the vertical direction,
Depending on the number of floors the elevator stops, the length may be 1 m to 1.8 m, so 4 to 6 fixing screws 2ri are used.

With the above structure, the fixing screws 2 naturally appear on the surface of the cover 1, which reduces the design value of the cover. On the other hand, the cover 1 must be easily removed from the case 3 during maintenance and inspection, but it takes time to remove the 4 to 6 fixing screws, and in reality, it is difficult to remove it easily. .

The present invention has been made in view of the above points, and an object thereof is to provide an elevator operation panel in which the design of the cover is improved and the cover is easily attached and detached.

That is, in order to achieve the above object, the present invention, when closing a case attached to a side wall with a cover, eliminates any fixing parts on the cover surface and engages with the case side on the back side of the cover, This engagement is effected by moving the case in the gravitational direction, and the engagement is released by moving the case in the anti-gravitational direction.

An embodiment of the present invention will be explained below with reference to FIGS. 3 to 9. For example, a vertically long rectangular case 9 is fixed to the side wall 12 of the elevator car. The entire front of this case 12 is open. Also, this case 9
Husband engaging pins IOA and IOB are provided in the upper and lower parts of the case to protrude along the width direction of the case. On the other hand, the engagement pins 10A are provided on the back surface of the cover 5 that closes the opening of the case 9.

Engagement plates 6A and 6B that engage with 10B are provided, respectively. The engagement plates 6A and 6B are attached in the vertical direction and extend in the depth direction of the case 9.

The engagement pin 10 is attached to each retaining plate 6A, 6B.
A retaining groove G that guides and engages A and 10B is formed. The locking groove G includes a guide groove G that guides the engagement pin 10A and IOB in a substantially horizontal direction, and a locking groove G that guides the engagement pin upward and engages with it. The retaining pin is formed to be guided and engaged in a substantially L-shape.

In addition, a stopper 11 extending toward the cover 5 is provided at approximately the midpoint in the vertical direction of the case 9, and a leaf spring 8 is attached to the cover 5 corresponding to this via a mounting seat 7. A part of the free end side of 8 is bent to form a retaining part 8.
A locking device is configured such that the engaging portion 8L is engaged with the lower surface of the stopper 11.

Furthermore, on the surface of the cover 5, parts of the push button 15 and the display 16 are exposed, and on the back side, the push button 15 and the display 16 are partially exposed, and on the back side, there are components of the push button 15 and the display 16, and other parts necessary for operating the elevator. Some of the devices P, , P2 are attached.

Further, the cover 5 below the free end 8a of the leaf spring 8 is provided with an opening 17 for operating a built-in operation operation switch P3, and a shutter 14 for closing this opening. is provided with a lock 13 for opening the shutter 14.

In the operation panel configured as described above, when trying to cover the opening of the case 9 with the cover 5, each retaining plate 6
A, 6B and each binding bin 10A.

Align the corresponding position of 10B. Next, each pin 10A.

Place the guide groove Gt of the retaining groove G on 10B (Fig. 6)
. At this time, in the locking device, as shown by the two-dot chain line in FIG. 8, the retaining portion 8L' of the plate spring 8' abuts against the tip of the stopper 11', thereby elastically deforming the plate spring.

In this state, the cover 5 is attached to the case 9.
When pushed to the side, the entire cover 5 moves under its own weight into an inverted shape opposite to the shape of the engagement groove G, as shown by the arrow C in FIG. 6, and the engagement pin 10A is moved.

10B is received on the engagement groove G2. At the same time, the leaf spring 8' also moves downward, and the engaging portion 8L' is moved to the stopper 11.
It comes off from the tip of the stopper 11 and engages with the lower surface of the tip of the stopper 11 (FIGS. 4, 8, and 9).

With the above operations, fixing of the cover 5 to the opening of the case 9 is completed.

By the way, the cover 5 has various parts p! on its back side. ,
Since the cover 5 is made to have a large self-weight by attaching the cover 5, its fixation will be stable unless an upward force greater than the self-weight is applied to the cover 5. However, the cover 5
Since the total weight of the vehicle is such that it can be lifted by a child, the cover 5 can easily come off due to mischief by a passenger. For this purpose, the locking device is provided, and since this locking device is also located on the back side of the cover 5, it is not easy to release the lock.

In addition, for maintenance inspection, the cover 5 is removed from the case 9.
If you want to remove it from above, first unlock the lock 13 with a special key, lower the shutter 14, and open the opening 17. The free end 8a'f of the leaf spring 8 is pulled forward through the open opening 17 to lock the engaging portion 8L and the stopper 11, and in this state, the cover 5 is lifted. Then, by releasing the free end 8a or 9 of the leaf spring 8 and pulling the cover 5 toward the front, the opening of the case 9 will be opened.

As described above, according to the embodiment of the present invention, there are no fixing parts on the surface of the cover 5 for fixing the cover 5 to the case 9, so the surface is simplified and the design effect is improved. be able to. Moreover, the attachment and detachment of the cover 5 does not require any screws or bolts, and can be easily done in a short time because it is sufficient to simply lift, push, or pull the cover 5. In addition, conventional screws and bolts use countersunk screws so that they are flush with the cover surface, but countersunk screws are difficult to align with the screw holes on the case side, and are difficult to align with the hole in the cover. However, in the embodiment of the present invention, the cover is not fixed with screws, so there is no such drawback.

- By the way, in the above embodiment, the locking device (
The leaf spring 8 and the stopper 11) are installed on the back side of the cup 5 between the upper and lower sides, but the installation location is not particularly limited. For example, it is also possible to provide it at the top or bottom end, thereby eliminating the work of unlocking and lowering the shutter.

Further, the locking device is constituted by a combination of a leaf spring 8 and a stopper 11, but this is also not particularly limited. You may also do so.

As explained above, according to the present invention, since no parts for fixing the cover are provided on the surface of the cover that closes the case, the design effect of the cover surface can be improved, and the cover (-) can be fixed. It does not use screws or bolts, but uses the weight of the hook to hook the hook, making it extremely easy to attach and detach.
