DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0008]
FIG. 2 is a perspective view showing an installed state of the elevator maintenance device according to the embodiment of the present invention.
[0009]
An opening 2A is formed in the wall 2 of the hall 1 on the predetermined floor, and a box 4 for accommodating the hall call device 3 is inserted into the wall of the opening 2A. In the steady state, the box 4 is provided with the hall call device 3 having the display unit 3B and the push button 3C. In the maintenance work state, the hall call device 3 is pulled out from the box 4, and this pulled-out state is indicated. The details are held by a hall call device holding device 7 described later. A connector 6 connected to an elevator control device (not shown) is provided in the box 4, and the portable terminal device 5 is connected to the connector 6 via a cable 10.
[0010]
FIG. 1 is an enlarged perspective view showing a main part of FIG.
[0011]
A wiring hole 4B is formed at the back of the box 4, and a wiring cable 11 having one end connected to an elevator control device (not shown) is inserted into the wiring hole 4B. The other end of the wiring cable 11 is It is connected to the display unit 3B and the push button 3C of the hall call device 3. A connector 6 connected to an elevator control device (not shown) is provided. The hall call device holding device 7 described above is composed of a box side holder 8 attached to the box 4 side and a hall call device side holder 9 and is provided in a pair on the upper and lower sides.
[0012]
A spring plate 12 is fixed to the inner lower surface of the box 4 with screws or the like, and the back plate portion 8A of the box side holder 8 is sandwiched by the spring plate 12. A pair of left and right ears 8B is formed on the distal end side of the box side holder 8, and the hall call device side holder 9 is inserted into the ear part 8B. The hall call device side holding tool 9 is fixed to the back side of the hall call device 3 with a fixing means such as a screw (not shown) on the opposite side of the hall call device, and the thickness is gradually reduced in the insertion direction. A tapered portion is formed. By firmly inserting the tapered portion into the ear portion 8B of the box-side holder 8, the hall call device 3 is held in a state protruding from the box 4 by a predetermined length. The upper hall call device holding device 7 has the same configuration.
[0013]
Next, maintenance work performed using the elevator maintenance apparatus described above will be described.
[0014]
First, the worker A pulls out the hall call device 3 attached to the box 4 on the wall 2, provides spring plates 12 on the upper and lower sides of the box 4, and attaches them to the box-side holder 8 locked to the spring plates 12. The hall call device holding device 9 is inserted to complete the hall call device holding device 7, and the hall call device holding device 7 holds the hall call device 3 in a state protruding from the box 4 by a predetermined length.
[0015]
Before and after that, the portable terminal device 5 is connected to the connector 6 provided in the box 4 via the cable 10. Next, the worker A operates the portable terminal device 5 to transmit / receive data to / from an elevator control device (not shown) to perform a predetermined maintenance work.
[0016]
During this maintenance work, even if a passenger who wants to use the elevator comes to the landing 1, the landing call device 3 is attached to the surface side via the holding device 7 for the landing call device. The push button 3C can be operated and the display unit 3B can be confirmed, so that maintenance work does not hinder the elevator user. Further, since the worker A only needs to explain to the user that the elevator can be used when the passenger approaches the landing 1, the maintenance work can be efficiently performed without being interrupted.
[0017]
FIG. 3 is a perspective view of an essential part showing an elevator maintenance apparatus according to another embodiment of the present invention.
[0018]
Usually, brackets 13 are fixed near the upper and lower portions of the box 4, screw holes 14 are formed on the surface side of the brackets 13, and screws 15 provided on the upper and lower portions of the hall call device 3 are screwed into the screw holes 14. In combination, the hall call device 3 is attached to the box 4.
[0019]
In maintenance work, first, the screw 15 is removed to separate the hall call device 3 from the box 4. Next, one hall call device side holding tool 9 constituting the hall call device holding device 7 is attached to the back side of the hall call device 3. The hall call device side holder 9 has an L-shaped bent portion 9B which is bent on the hall call device 3 side, and a screw portion is formed in the bent portion 9B. 3, a hall calling device side holding tool 9 is attached to the rear surface side of 3. The other box-side holder 8 constituting the hall call device holding device 7 is configured by forming an insertion portion between the upper surface of the box 4 and the bracket 13. The hall call device side holding tool 9 has a plate shape having a predetermined length, and when the tip side thereof is inserted into the box side holding tool 8 between the upper surface of the box 4 and the bracket 13 and stabilized, the above-described implementation is performed. Similarly to the case of the embodiment, the hall call device 3 can be held in a state of protruding from the box 4 by a predetermined length.
[0020]
Thus, since the box side holder 8 is configured using existing components, the configuration can be simplified. Moreover, the loss of the screw 15 that is easily lost can be prevented by using it during maintenance work.
[0021]
【The invention's effect】
As described above, the elevator maintenance apparatus according to the present invention is provided with the hall call device holding device that holds the hall call device in a state of protruding a predetermined length from the box when the portable terminal device is connected to the connector. There is no need to put a burden on the cable of the hall call device, the connection between the cable and the base, or damage the surrounding design members, and the elevator can be used almost normally by the temporarily held hall call device. .
