Description

  The present invention relates to a work floor in which a movable floor is provided on one end of a main body floor portion via a hinge.

Conventionally, a work floor provided with a movable floor via a hinge has been supplied to one end of the main body floor.
In particular, work floors used for work to remove, maintain, and inspect work sites on large wall surfaces must be performed efficiently and in a short time, but work at work sites close to the work floor requires work. The floor hindered work, making it difficult to work and hindering efficiency. Therefore, a work floor with high workability has been desired over the entire wall surface.
As an example, in the work of inspecting the MRF of the telephone line, which is said to be a telephone company's concentrating station, and performing the installation and removal, etc. The floor was desired.

Therefore, as shown in FIG. 7, a work floor is provided in which a movable floor is provided at one end of the work floor via a normal hinge 26 and the work floor can be opened upward.
However, it has the following drawbacks.

(2) Even if it opens until it reverses, if it closes downward due to some momentum, there is a possibility of hitting the worker who was working there and causing a danger.
(3) Since the floor of the movable floor is made of a material that cannot be seen through, the line of sight cannot be seen, and the operator on the movable floor cannot be confirmed when viewed from below as shown in FIG. Since the worker under the movable floor cannot be confirmed from above the floor, there is a possibility of hitting the worker below when the movable floor is closed.
(4) Since the floor surface of the movable floor is made of a material that does not transmit light, the lower portion of the movable floor is dark, so that the brightness is insufficient, and it is necessary to separately provide lighting or the like, which is not preferable in terms of energy saving.

It is made of a translucent plate-like member and is lightweight.

When the strength is sufficient only by the floor plate 3a, it is not necessary to provide the beam set 3b. Usually, the beam set 3b is provided below the floor plate 3a to increase the strength, and the floor plate 3a is fixed.
The beam set 3b may be made of a normal metal such as iron or aluminum, and is preferably made of a synthetic resin such as FRP (fiber reinforced plastics) that is lightweight and slightly transmits light, and is lightweight. . Moreover, it has the advantage which does not receive the influence of electromagnetic waves by using non-metal.

  Since the floor plate 3a and / or the beam assembly 3b are lightweight, when the floor plate 3 is opened upward as shown in FIG. 5, the floor plate 3a and / or the beam assembly 3b can be fixed with a small torque. 3 can be fixed at an open / close position at an arbitrary angle by the friction torque of the torque variable hinge 4.

Further, as shown in FIG. 3, the first fixed piece 5 of the variable torque hinge 4 is attached to one end of the main body floor 2 of the work floor 1 by a fixing means such as a bolt / nut, welding, adhesion or the like. ing.
The second fixed piece 6 of the variable torque hinge 4 is attached to one end portion of the movable floor 3 of the work floor 1 by a fixing means such as a bolt / nut, welding, adhesion or the like.
On the outer peripheral surface of the shaft 7 that engages the first fixed piece 5 and the second fixed piece 6, a friction piece 8 that generates a frictional force in contact with a part or all of the outer peripheral surface of the shaft 7 is provided. It has the pressing piece 9 arrange | positioned.
