Abstract

PURPOSE: To improve safety by making the conveyance of an indication plate unnecessary and preventing its removal by making arrangement so that the indication plate provided appearingly/disappearingly at a hall floor may be protruded onto the hall floor and its state may be retained by means of lock mechanisms. CONSTITUTION: An indication plate housing box 11a is imbedded at the hall entrance front of an elevator hall floor 11, and an indication plate 12 is housed so as to be able to be taken in and out freely. 'Under inspection' indication is made at the display of the indication plate 12. A pulling out handle 18 is turnably provided at the upper end portion of the indication plate 12, and on both sides of it, turnable indication plate 12 fixation metal fittings 19 are respectively provided. The indication plate 12 fixation metal fittings 19 are made appearable/disapperable from the side parts of the indication plate 12 by means of turning movements, and constitute lock mechanisms 30. The indication plate 12 fixation metal fittings 19 appear/disappear through coupling rods 21 by the operation of operation levers 20. The lock mechanisms 30 are provided one set by one set on the right and left of the indication plate 12. At the time of inspection, the indication plate 12 is projected from the housing box 11a, and the indication plate 12 fixation metal fittings 19 are projected by means of the operation levers 20, and retain the indication plate 12 in a standing up position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator inspection display device which is provided at an elevator hall during inspection and indicates that the elevator is under inspection.

[0002]

2. Description of the Related Art FIG. 10 is a perspective view showing an example of a state of a hall during inspection in a conventional elevator. In the figure, 1 is a three-sided frame provided at the entrance / exit of the hall, 2 is a push-button for registering a hall provided on the wall of the hall, 3 is a door for opening and closing the entrance / exit of the hall, 4 is a magnet or the like on the top of the three-way frame 1. The detachable inspection tag 5 is a safety fence placed on the floor of the hall so as to surround the hall entrance.

In such a conventional elevator, it is necessary for an operator to carry at least one of the inspection tag 4 and the safety fence 5 from the storage location to each landing and install them as shown in the figure during the inspection work. . This alerts the user that the inspection is in progress and alerts the user, and prevents the user from entering the vicinity of the entrance / exit of the hall.

[0004]

However, in the above-described conventional inspection display device, that is, the inspection tag 4 and the safety fence 5, these must be carried from the storage place to each landing each time the work is performed. There was a problem that it took time and effort. Further, since the inspecting tag 4 is attached by a magnet or the like, there is a problem that it may be blown off by a gust of wind or easily removed due to mischief. Further, the safety fence 5 is not easily removed as compared with the tag 4 under inspection, but there is a problem that it takes a very long time to install it at the halls on all floors.

The present invention has been made to solve the above-mentioned problems, and it is easy to carry and is not easily removed, thereby improving safety. It is an object of the present invention to obtain an elevator inspection display device that can be used.

[0006]

According to a first aspect of the present invention, there is provided an elevator inspection display device, which includes a display plate which is provided in a landing floor in front of a landing entrance and exits so that the information can be displayed during the inspection. And a lock mechanism for holding the protruding state of the display plate when used.

An elevator inspection display device according to a second aspect of the present invention includes a display plate stopper member which is provided so as to be retractable from the outer peripheral portion of the display plate and projects when the display plate is used to support the display plate with respect to the landing floor. The lock mechanism is provided on the display board and is connected to the display board stopping member via a connecting means and has an operating lever for retracting the display board stopping member.

[0008]

According to the first aspect of the present invention, during use, that is, at the time of inspection work, the display plate is projected on the floor of the landing and the state is held by the lock mechanism to indicate to the user that the inspection is being performed. , Prevent users from entering the hall entrance.

According to the second aspect of the present invention, by operating the operation lever, the display plate stopping member is retracted from the outer peripheral portion of the display plate through the connecting means to lock / unlock the lock mechanism.

Embodiments of the present invention will be described below with reference to the drawings. Example 1. 1 is a schematic perspective view showing a landing of an elevator using an inspection display device according to Embodiment 1 of the present invention, FIG. 2 is a sectional view of an essential part of FIG. 1, and the same or corresponding parts to those in FIG. Is attached and the description thereof is omitted.

In the figure, 11 is a hall floor, and a display board storage box 11a is embedded in front of the hall entrance / exit of the hall floor 11. Reference numeral 12 is a display plate that is freely inserted into and removed from the display plate storage box 11a, and the surface of the display plate 12 is displayed as "Inspection in progress". Further, 13 is a landing side door shoe provided at the lower end of the landing door 3, 14 is a landing sill, 15 is a car door, 16 is a car side door shoe provided at the lower end of the car door 3, and 17 is a car. It is a threshold.

FIG. 3 is a configuration diagram specifically showing the pulled-out state of the display plate of FIG. In the figure, 18 is a display plate 12.
A pull-out handle rotatably provided at the upper end of the display plate 19 is a display plate stopper fitting, that is, a display plate stopper member, rotatably provided in the display plate 12.
The reference numeral 9 is adapted to be projected and retracted from the side portion of the display plate 12 by rotating.

Reference numeral 20 denotes an operation lever rotatably provided in the display plate 12, and the operation lever 20 is connected to the display plate stopping member 19 via a connecting rod 21 which is a connecting means. The display plate 12 is provided with an opening 12a for operating the operation lever 20. In addition, FIG.
As shown in the enlarged view of FIG.
It is urged by 2 in a direction projecting from the display plate 12. Furthermore, the lock mechanism 30 of the first embodiment includes the display plate stopper member 19, the operation lever 20, the connecting rod 21, and the spring 2.
2, and one set is provided on each side of the display plate 12.

FIG. 4 is a structural view showing a state in which the display plate stopper member 19 of FIG. 3 is retracted, and FIG. 5 is a display plate 12 of FIG.
6 is an enlarged view of a main part of FIG. 1, FIG. 7 is a plan view showing an operation lever 20 of FIG. 6, and FIG. 8 is a plan view showing a display plate stopping member 19 of FIG. .

Next, the operation will be described. Normally, the display board 12 has an upper end portion thereof as shown in FIG.
It is stored in the display board storage box 11a so as to be flush with the floor surface of the display board. When the elevator is inspected, the display handle 12 is pulled out by using the pull-out handle 18. The pull-out handle 18 has a structure in which the grip portion appears by pushing and rotating the end portion thereof.

When the display plate 12 is pulled out to the position of the display plate fixing member 19, as shown in FIG.
Is urged by the spring 22 to project from the side portion of the display plate 12. As a result, even if the pulling handle 18 is released, the display plate 12 is supported on the landing floor 11 by the display plate stopping member 19, and the protruding state of the display plate 12 is maintained.

To store the display board 12 from this state,
The operation lever 20 is pulled upward from the opening 12a and rotated. As a result, the operation lever 20 is connected via the connecting rod 21.
