DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, an optical fiber connection work table 1 is detachably provided on a riding bucket 2 of a bucket truck (not shown) for working at a high place. A pair of hooks 3,3 engaging with the rim, pressing portions 4,4 extending downward from the hooks 3,3 to contact the wall surface of the riding bucket 2, and extending horizontally between the pressing portions 4,4; And a table section 5 provided out.

As shown in FIG. 1 and FIG.
Are formed by bending the upper end of a vertically long metal plate into a U-shape, and are arranged apart from each other in the horizontal direction.

The holding portions 4, 4 are formed of metal plates extending below the hooks 3, 3, respectively, and have bent portions 7, 7 formed at their lower ends toward the wall surface 6 of the riding bucket 2. . In the middle of each holding part 4, 4,
Two holes (not shown) for passing the bolts 8 are formed vertically apart.

The table portion 5 has a fixed portion 10 fixed between the holding portions 4 and 4 via bolts 8 and nuts 9, and an extending portion formed to extend horizontally from the upper end of the fixed portion 10. And an outlet 11.

The fixing portion 10 and the extension portion 11 are each formed by bending a single metal plate into an L-shape, and near the four corners of the fixing portion 10 are overlapped with the holes of the holding portions 4, 4. A hole (not shown) through which the bolt 8 penetrates is formed.

The extension portion 11 has a flange portion 12 formed by bending the extension end upward so that a tool or the like placed on the extension portion 11 is not dropped from the extension end side. .

Next, the operation will be described.

When the work table 1 for connecting optical fibers is mounted on the riding bucket 2 of the bucket truck for working at height, the hooks 3 of the work table 1 for connecting optical fibers are hooked on the upper edge of the riding bucket 2; The protruding end of the bent portion 7 is brought into contact with the wall surface 6 of the riding bucket 2.

By doing so, the work table 1 for optical fiber connection work is fixed to the riding bucket 2 with the extending portion 11 of the table section 5 extending horizontally from near the upper edge of the riding bucket 2. , Can be easily attached to the riding bucket 2.

Then, an optical fiber fusion splicer (not shown) is placed on the extension portion 11, and connection of the optical fiber is started. At this time, the weight of the optical fiber fusion splicer is
The hooks 3, 3 hooked on the upper edge of the riding bucket 2 are dispersed and supported by a force for pulling the hooks 3, 3 downward and a force for pressing the bent portions 7, 7 of the pressing portions 4, 4 against the wall surface 6 of the riding bucket 2. Therefore, the optical fiber connection work table 1 does not tilt or fall.

Further, since the optical fiber fusion splicer is located near the upper edge of the riding bucket 2, an optical cable (not shown) having a short extra length can be easily connected.

Since the work table 1 for optical fiber connection work does not have a leg or the like below the extension portion 11, the inside of the riding bucket 2 can be widely used.

When the work table 1 for connecting optical fibers is removed from the riding bucket 2, the work table 1 for connecting optical fibers can be removed from the riding bucket 2 only by lifting the work table 1 upward.

Next, another embodiment will be described.

As shown in FIGS. 3 and 4, the work table 20 for connecting optical fibers has a pair of hooks 22, 22 engaged with the upper edge of the riding bucket 21, and extends downward from the hooks 22, 22.

In the connection operation of the optical fiber, cutting debris comes out because the coating is peeled off or the end of the optical fiber core wire is cut off. Since it is dropped and stored in the drawer 32 from the many holes 40 formed in the work plate 31, the riding bucket 21
It can be prevented from scattering inside or on the road, and can be easily cleaned after the work is completed.

When screws or nuts or the like to be temporarily stored are generated by disassembling the connecting device during the optical fiber connecting operation, the screws and nuts are placed on the tray 41 so that the holes in the working plate 31 are removed. It can be prevented from falling from 40 and getting together with the cutting waste in the drawer 32.

Since the optical fiber fusion splicer 47 is located near the upper edge of the riding bucket 21, an optical cable having a short length can be easily connected. 20 does not have a leg or the like below the extension, so that the inside of the bucket is not narrowed.

When the optical fiber connection operation is completed, the optical fiber fusion splicer 47 is lowered from the drawer 32, the stopper 44 of the drawer 32 is removed from the frame 30, the drawer 32 is pulled out of the frame 30, and the drawer 32 is pulled out. Discard the cuttings inside.

Then, the drawer 32 is returned into the frame 30 again, and the work table 20 for optical fiber connection work is lifted upward and removed from the riding bucket 21.

When the optical fiber fusion splicer 47 is not used, a single work plate having a large number of holes 40 is used for the frame 3.
The upper opening 29 may be closed, and may be used for other height work other than the optical fiber connection.
