Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work scaffold for an automatic door suitable for performing maintenance work on an automatic door.

[0002]

2. Description of the Related Art Conventionally, when performing maintenance work on an automatic door, a stepladder is installed in the vicinity of the automatic door, and a maintenance person stands on the stepladder and reaches for a drive unit of the automatic door. Maintenance work such as driving of the vehicle.

[0003]

In the above-mentioned prior art, the maintenance and inspection work of the automatic door must be performed while the maintenance staff is on the stepladder, and the maintenance staff is in an unstable working posture and lacks safety. There was a problem that. Moreover, the width of the automatic door is generally as long as about 2 m. For this reason, it is necessary to repeat the operation of moving the stepladder laterally in a state where the maintenance person gets down from the stepladder and the maintenance person gets on the stepladder again and again, and there is a problem that workability is poor. In addition, there is a problem that a passer who opens and closes the automatic door cannot understand why the stepladder is installed near the automatic door, and the passerby becomes uncomfortable.

An object of the present invention is to provide a work platform for an automatic door which can solve the above problems with a simple structure.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a work platform for an automatic door comprising a tread frame and a pair of ladder-like support legs foldably provided on the tread frame. This is achieved by attaching a slipping material to the upper surface of the tread frame and detachably providing an alerting indicator that alerts the user that the work is being performed in front of the tread frame.

[0006] According to this configuration, the work can be moved laterally on the tread frame, and the workability is improved. Further, the maintenance staff can stand on both sides of the tread frame, and the maintenance staff can perform maintenance and inspection of the automatic door in a stable posture. In addition, the warning sign indicates that the pedestrian is performing maintenance work on the automatic door, and even if a work platform is installed near the automatic door, the pedestrian will not be uncomfortable and safe. Through the automatic door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a work platform for an automatic door is provided with a tread frame 2 and a pair of ladder-like support legs 3 and 4 foldably provided on the tread frame 2. The tread frame 2 has a substantially rectangular shape, and a slip agent 5 is attached to the upper surface thereof. The tread frame 2 is made of aluminum to reduce its weight. Ladder support legs 3, 4
An elastic cap 6 made of rubber or the like is attached to the lower end of the cover. The elastic cap 6 prevents the lower ends of the ladder-like support legs 3 and 4 from directly contacting the floor surface and damaging the floor lower surface. The ladder-shaped support legs 3 and 4 are made of aluminum to reduce the weight. Upper end portions 3A, 4A of the ladder-shaped support legs 3, 4 are foldably attached to side end portions of the tread frame body 2.

At the center of the front of the tread frame 2, FIG. 1 and FIG.
As shown in FIG. 7, the alerting member 7 is provided detachably using an adhesive tape or the like. The alerting body 7 is made of synthetic resin having a well-formed shape. On its surface, a sign 7 consisting of characters and pictures indicating that maintenance and inspection work of the automatic door is being performed.
A is given. The tread frame 2 preferably has a length L1 of about 900 mm along the side of the automatic door in FIG. 1 and a width L2 of about 320 mm. The height L3 (see FIG. 2) of the work platform 1 is approximately 800
mm is preferable. At the outermost periphery of the tread frame 2,
By sticking an elastic material such as rubber, the outermost part does not directly touch the glass etc. of the automatic door,
The glass and the like are prevented from being damaged.

In the above configuration, when performing maintenance and inspection of the automatic door, the work platform 1 is set to the state as shown in FIG. 1, and the display 7A of the alerting member 7 is displayed from the opposite side to the automatic door. Make it visible.

Next, a maintenance worker rides on the tread frame 2 of the work platform 1 with both feet, and performs maintenance and inspection of the automatic door while moving laterally on the tread frame 2. In this case, the maintenance staff can work in a state in which both feet are slightly opened and the hand is extended straight upward toward the drive unit of the automatic door, and it is possible to maintain a stable working posture. So,
Maintenance inspection work can be performed safely and efficiently.

Next, when the maintenance work of the automatic door is completed, as shown in FIG. 3, the ladder-like support legs 3, 4 are folded to transport the work platform 1 in a compact state. Further, it may be stored in a predetermined storage place.
In this case, the work platform 1 is compact, so that it is easy to hold and easy to store.

In the present embodiment, the ladder-like support legs 3, 4
Although the length does not change, it may have a stretchable structure so that the length changes. Further, the tread frame body 2 may have an expandable / contractible structure such that its dimension L1 changes.

[0014]

As described above, according to the present invention, a work scaffold for an automatic door is provided which enables a safe posture and smooth maintenance work of the automatic door.
