Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety fence device which is installed at an entrance / exit of a device such as an escalator when inspecting the device.

[0002]

2. Description of the Related Art Conventionally, a safety fence device has a structure in which a plurality of fence bodies are foldably connected to each other, and is in a folded state at the time of transportation, and when it is installed at the entrance / exit of equipment, It was in a state of being spread out so that no one would enter it.

Further, the place where the safety fence device is stored is generally separated from the entrance / exit of the equipment to be inspected.

[0004]

In the above-mentioned conventional safety fence device, it is necessary to carry the equipment together with tools for inspecting the equipment and carry it from the storage location to the entrance of the equipment. There was a problem.

An object of the present invention is to provide a safety fence device which can reduce the burden on maintenance personnel during transportation of the safety fence device with a simple structure.

[0006]

[Means for Solving the Problems] The above object is to provide a safety fence device which is arranged at the entrance and exit of the equipment when the equipment is inspected, and in which a plurality of fence bodies are foldably connected to each other.
One wheel is provided at a lower corner of any one of the plurality of fences so that the wheel surface thereof projects outward from the lower corner and the surface of the wheel is cleaned. This is achieved by arranging the cleaning body near the wheel.

According to such a construction, in the state where the plurality of fences are folded and the wheels are positioned in the lower part in the anti-moving direction, the plurality of fences are grasped at the upper part and tilted rearward and forward. By pulling to, the floor surface can be smoothly moved by one wheel of the plurality of fences.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a device 1 such as an escalator
A safety fence device 2 is installed at the entrance / exit 1A at the time of inspection. The safety fence device 2 has a structure in which a plurality of fence bodies 3, 4, 5, 6, 7 are foldably connected. One wheel 8 is provided at the lower side corner portion 3A of one of the plurality of fences 3, 4, 5, 6, 7 as shown in FIG.

The wheel 8 is fixed to a support column forming the fence 3 with a mounting bracket 9.

The wheel 8 is provided with a cleaning body 10 made of a rigid brush for cleaning the surface of the wheel 8.

As shown in FIG. 4, the mounting bracket 9 has wheels 8
The support frame 8A and the support 10A of the cleaning body 10 are fixed together by two fasteners 11 and 11A. The support 10A is formed of a spring so that the cleaning body 10 elastically contacts the surface of the wheel 8.

When the fences 3, 4, 5, 6, 7 are spread and the wheels 8 are erected on the floor, a gap G is formed between the wheels 8 and the floor as shown in FIG. Fence body 3
Mounted in the corner of.

As shown in FIG. 4, the wheels 8 are positioned between the fence body 3 and the fence body 5 when the safety fence device 2 is folded.

In order to move the safety fence device 2 having the above configuration from the storage location to the entrance / exit 1A of the equipment 1, the maintenance worker A grasps the folded safety fence device 2 as shown in FIG. By pulling, the safety fence device 2 may be moved on the floor surface B by the wheels 8. Dust adhering to the wheel 8 as the wheel 8 rolls on the floor B is removed by the cleaning body 10.

According to the safety fence device 2 having the above structure, the following advantages can be obtained.

(1) When transporting the safety fence device 2 from the storage location to the entrance / exit 1A of the device 1, the safety fence device 2 is floored by the wheels 8 without lifting the entire folded safety fence device 2 from the floor surface B. Since it is sufficient to move along the surface B, the burden on the maintenance personnel A is reduced.

(2) When the safety fence device 2 is spread and installed, the wheels 8 do not come into contact with the floor surface B, so that the wheels 8 do not interfere with the installation.

(3) Since the wheels 8 are located between the fence 3 and the fence 5 when the safety fence device 2 is folded and transported, the legs of the maintenance personnel A and the entrance / exit 1A of the equipment 1 It is safe because it does not come into contact with the surrounding objects while moving to.

(4) The safety fence device 2 can be moved along the floor surface with one wheel 8, and the structure is simple and the manufacturability is excellent.

(5) While the wheel 8 is moving on the floor B, the dust adhering to the wheel 8 is always removed by the cleaning body 10. Therefore, the dust adhering to the wheel 8 stains the floor B. You can prevent it from getting lost.

(6) If the material of the wheel 8 is elastic, even if the floor B is moved by the wheel 8, the floor B is not damaged.

(7) Generally, two sets of safety fence devices 2 are required, but there are cases where four sets of safety fence devices 2 are required depending on the work. From the storage place including other tools to the equipment 1. The burden on the operator can also be reduced by attaching the wheel 8 to the transportation.

[0024]

As described above, according to the present invention, since the safety fence device is moved on the floor surface by one wheel without lifting, the burden on the maintenance staff can be reduced, and A safety fence device with a simple structure that can remove dust adhering to the surface of the wheels rolling on the floor was obtained.
