  In recent years, machine room-less elevators have become mainstream. In such machine room-less elevators, when performing maintenance and inspection of elevator equipment such as brakes, inspection work for checking the state of the equipment from outside the hoistway is increasing in order to ensure the safety of workers. On the other hand, the dedicated cable for maintenance laid from the control panel in the hoistway is housed inside the operation panel case installed in the back of the operation panel plate provided near the landing. A special operation is performed using the cable, or the elevator control circuit is short-circuited and the maintenance terminal is operated. At that time, the inspection operator needs to remove the operation panel plate, connect the maintenance terminal to the maintenance cable inside the operation panel case, and operate the maintenance terminal.

  As such a removal technique, although not intended to remove the elevator hall operating panel, an invention described in Japanese Patent Laid-Open No. 7-124872 (Patent Document 1) is known. An object of the present invention is to make it easy to remove a module when a large number of modules are installed adjacent to each other. The hook of the module removal jig is narrowed and curved to be hooked on the module. The other end is formed as a drawer portion having a large curvature, and the module can be easily pulled out by hooking the hook portion to the opening of the side wall of the module and applying a force in the removal direction. Specifically, it is a flat plate-like member having a thin tip, and has a hook portion with the tip bent at least 90 ° and a drawer portion formed by bending the other end at least 90 ° or more. Has been proposed.

JP 7-124872 A

  An operation panel on the elevator landing side is composed of an operation panel plate facing the front side of the landing and an operation panel case embedded in the building wall. The operation panel plate is held in the operation panel case by a plate spring that cannot be easily opened by elastically deforming a plate-like claw portion provided on the operation panel plate. In such a configuration, in order to carry out the maintenance work of the elevator safely and easily, the maintenance terminal is connected to the maintenance cable stored in the operation panel case on the elevator landing side, or a special operation is performed, or Although the elevator control circuit is short-circuited and the maintenance terminal is operated for other maintenance work, it is necessary to remove the operation panel plate on the landing side.

  As described above, the operation panel plate is elastically held in the operation panel case by the claw portion made of a leaf spring, the thickness of the operation panel plate is several millimeters, and the surface of the operation panel plate is only the thickness. When the elevator maintenance worker performs the work of opening the operation panel plate for maintenance work due to the fact that it does not protrude, a driver is inserted into the slight gap between the operation panel plate and the building wall to pry it open. If the driver is used to pry it open, the edge of the building wall or the operation panel case may be damaged.

  On the other hand, in the above-mentioned known example, the module removal jig is intended to facilitate the removal of the module, but the object to be removed is a module mounted on the base by a snap fit, and the side wall of the module. The side wall of the edge of the opening provided in is hooked so as to be sandwiched and pulled out in a direction parallel to the side wall. For this reason, it is difficult to insert the tip between the building wall and the operation panel in a direction perpendicular to the operation panel surface like the operation panel on the elevator landing side.

  For this reason, the maintenance staff can open the operation panel plate only with the fingertips of the hand, but it is not easy to open the operation panel plate because it can be opened only with the force of the fingertips. In addition, it is assumed that the fingertips are damaged when opening, and it is considered that the wall near the building wall around the operation panel plate portion is soiled.

  Therefore, the problem to be solved by the present invention is to make it possible to easily remove the operation panel plate of the elevator operation panel and to perform maintenance work efficiently.

In order to solve the above problems, the present invention provides an operation panel case installed on a building wall of an elevator hall, the front side of the operation panel case is covered with an operation panel plate, and the operation panel plate is held in the operation panel case An engagement portion is formed in advance on the back side of the edge of the operation panel plate of the elevator operation panel elastically held by the means, and the engagement portion is hooked on the engagement portion; An operation part for applying force in a direction away from the wall surface in a state where the joint part is hooked is hooked on the engaged part of the detaching jig formed integrally with the wire, and the engagement A force is applied to the removal jig in a direction perpendicular to the surface on the front side of the operation panel plate in a state in which the operation panel plate is hooked, and the operation panel plate is released from the holding force of the holding means. take The operation panel plate is removed, and the engaged portion has a plane portion whose angle formed with respect to the end surface of the operation panel plate is θ1 on the back side of the edge of the operation panel plate in advance, The operation portion includes a ring-shaped portion having elasticity formed by winding the wire rod a plurality of times, and the engagement portion is a protrusion formed at the tip of the wire rod protruding outward from one end of the ring-shaped portion.

The structure of the jig and the operation panel is proposed. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a state of a general elevator hall. In the figure, an elevator hall 10 is provided with an opening 1a of a building wall 1 at the front, and an elevator hall door 2 is installed at the back of the opening 1a so as to be openable and closable. On the right building wall 1 in the figure of the opening 1a, an operation panel (elevator operation panel) 3 is provided for a passenger who gets on the elevator to call the elevator.

  2 is a cross-sectional view taken along line AA of the operation panel in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB of the operation panel in FIG. In these drawings, the operation panel 3 includes a case (hereinafter referred to as an operation panel case) 4 and an operation panel plate 31, and a first and second pair of claw portions 34 a and 34 b are provided on the back side of the operation panel plate 31. Is provided. The first and second claw portions 34 a and 34 b are plate-like, and are provided at positions that can be perpendicular to the rear surface of the operation panel plate 31 and along the vertical side wall 4 a of the operation panel case 4. .

  A mounting portion 1a of the operation panel case 4 is opened on the wall surface of the building wall 1 of the platform 10 near the landing door 2, and the operation panel case 4 is mounted on the opened mounting portion 1a. It is fixed.

  As shown in FIG. 3, the platform operating panel plate 31 is inserted between first and second leaf springs 41 a and 41 b extending from the back surface side to the side surface of the operating panel case 4 and the side wall 4 a of the operating panel case 4. Accordingly, the first and second claw portions 34a and 34b are sandwiched between the first and second leaf springs 41a and 41 and the side wall 4a and are fixed in a state of being elastically pressed. The operation panel plate 31 is provided with a display base 32 and operation buttons 33 for displaying the position of the elevator car, and a display cover 35 for protecting the display base 32 is provided on the surface. The display board 32 of the operation panel plate 31 is connected to the operation board cable 51 of the control cable 5 laid from within the hoistway, and the display board 32 and the operation buttons 33 are connected to each other through the connection cable 6. .

  The passenger presses one of the upper and lower buttons on the operation panel 3, calls the elevator to the floor where the passenger is located, and instructs whether the direction he wants to go is up or down. Since FIG. 1 shows the elevator floor on the lowest floor, only the upward direction of the operation button 33 is shown. In addition, a maintenance connector 52 necessary for maintaining the elevator is drawn into the hoistway and mounted in the operation panel case 4 of the operation panel 3 of the lowermost landing.

  FIG. 4 is an enlarged view showing a lower portion of the operation panel plate 31 in the cross section of FIG. As can be seen from the figure, a notch 31 a is provided in the lower center of the operation panel plate 31. This notch 31a is for opening the operation panel plate 31 using a jig 7 to be described later. An operation projection 72 of the jig 7 is inserted into the notch 31a, and a building in the vicinity of the notch 31a. The width and length of the operation panel plate 31 may be provided so that the operation panel plate 31 can be separated from the operation panel case 4 without interfering with the wall 1.

  5 to 7 are for explaining a jig for pulling out the operation panel plate in the present embodiment. 5 is a front view, FIG. 6 is a plan view, and FIG. 7 is an enlarged right side view of FIG.

  As shown in FIGS. 5 and 6, the jig 7 includes an operation protrusion 72, an operation portion 73, and a linear protrusion 74, and is integrally formed by forming a round bar. The operation unit 73 includes a ring-shaped portion 71 that is intended to allow a maintenance worker's finger to enter, with a round bar wound in a coil shape a plurality of times. The operation projection 72 is provided at the tip of a projecting portion 74 that projects radially and linearly outward from a portion where one end of the ring-shaped portion 71 is estimated to be the center of the ring-shaped portion 71. As can be seen from FIG. 5, the front end of the projecting portion 74 is bent in an L shape in front view, and the bent portion can be hooked on the notch 31.

  The round bar is made of copper or a resin material, and is a wire having a diameter of about 3 mm (= φB). The ring-shaped portion 71 has a diameter (φA) of about 30 mm inside diameter. The diameter φA of the ring-shaped portion 71 is set to an inner diameter of about 30 mm so that the maintenance worker's finger can enter. However, the maintenance worker's finger enters, and the ring-shaped portion 71 is hooked and operated. Therefore, it is not limited to the inner diameter. The round bar is wound in a coil shape a plurality of times (2.5 turns in the drawing). This is because the force applied to the finger of the maintenance worker is dispersed when the jig 7 is hooked with a finger and operated by being wound a plurality of times.

  As shown in FIG. 5, the operating protrusion 72 has a height direction dimension (hereinafter referred to as “height dimension”) L1, and a thickness direction dimension (hereinafter referred to as “thickness dimension”) L2. As shown in FIG. 4, the height dimension L1 is set to be equal to or smaller than the dimension La in the vertical direction (insertion direction of the operation projection 72) in the lower cutout view as shown in FIG. As shown in FIG. 4, the thickness dimension L2 is set to be equal to or less than the dimension Lb in the thickness direction of the notch. Thereby, the operation projection 72 of the jig 7 can surely enter the operation panel plate lower notch 31a provided at the lower part of the operation panel plate 31 of FIG.

  As shown in FIG. 6, the operation projection 72 is formed so that the tip of the round bar is flat, and the protrusion 74 is also formed to be flat and wide at the portion connecting to the operation protrusion 72. It is molded so that a round bar shape remains on the part 71 side. In other words, it is formed so as to be gradually flattened from the round bar portion, and then the tip is bent so as to enter the gap between the operation panel plate lower notch 31a and the building wall 1. . This shape is also apparent from the shape of the tip of the operation projection 72 in FIG.

  As can be seen from FIGS. 6 and 7, the dimension in the width direction of the operation projection 72 (hereinafter referred to as “width dimension”) L3 is the dimension in the width direction of the notch 31a below the operation panel plate (in FIG. 4). It is narrower than the direction perpendicular to the paper. Further, the bent distal end 72a of the operation projection 72 has an arc shape with a radius R1 so that the edge is eliminated as much as possible. Thus, when the operation protrusion 72 of the jig 7 is inserted into the operation panel plate lower notch 31a, even when the building wall 1 of the landing is touched, the wall is not damaged.

FIG. 8 is an operation explanation showing a work process when the operation panel plate 31 is removed from the case 4. When removing the operation panel plate 31 from the case 4,
1. First, in the first step, the maintenance worker inserts the finger 8 into the ring-shaped portion 71 of the jig 7.

2. In the second step, the operation protrusion 72 of the jig 7 is inserted inside the notch 31a at the lower part of the operation panel plate (FIG. 8A). At this time, as shown in FIGS. 2 and 3, the operation panel plate 31 is pressed against the side wall 4a of the operation panel case 4 by the first and second leaf springs 41a and 41b, and the first and second leaf springs 41a. , 41b is held in the operation panel case 4 by the elastic force.

3. In the third step, as shown in FIG. 8B, the maintenance worker uses the finger 8 to place the jig 7 in a substantially horizontal direction and in the direction of his / her body (a direction substantially perpendicular to the surface of the operation panel plate 31 : In the direction of arrow D1). As a result, the operation panel plate 31 is pulled out against the elastic force of the first and second leaf springs 41a and 41b, and the operation panel plate 31 can be opened.

  At this time, it is preferable that the portion of the operation projection 72 bent in an L shape is set to an angle along the inclined surface 31b of the operation panel lower notch 31a. For example, when the bending angle θ of the operation projection 72 shown in FIG. 5 is 90 ° or more, when the operation projection 72 is inserted into the operation panel lower notch 31a, the convex portion 75 outside the bent portion is formed. A force may be applied by touching the building wall 1 of the platform. Further, when the bending angle θ is larger than the angle θ1 formed by the inclined surface 31b with respect to the surface of the lower end 31c of the operation panel plate 31, the distal end portion 72a of the operation projection 72 touches the building wall 1 of the landing, and the force May be added. If the convex part 75 touches the building wall 1 or the tip part 72a touches the building wall 1, the possibility of scratching the wall increases, which is not preferable.

Therefore, the bending angle θ of the operation projection 72 is
θ1 ≦ θ <90 °
It is good to select in the range.

  In the present embodiment, the notch 31a is provided in the lower part of the operation panel plate 31, but it may be a groove or a recess into which the operation projection 72 can be engaged instead of the notch 31a.
