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

FIG. 1 is a plan sectional view showing a structure in which a car room entrance / exit vertical column holder according to the present invention is attached to a vertical column. FIG. 2 is a side sectional view taken along line AA 'in FIG. Further, FIG.
Is a side sectional view taken along line BB 'of FIG. The same components as those in the related art are denoted by the same reference numerals, and the description thereof is omitted.

The fixing bracket 5 is firmly fixed to the car floor 14 by bolts 6. On the other hand, a semicircular holding plate 7 is provided between the fixing bracket 5 and the inner surface of the car room entrance / exit vertical column 2 (hereinafter, referred to as “vertical column 2”). Furthermore,
As shown in FIG. 2, the holding plate 7 has a box-like structure having an upper surface so as to cover a part of the fixing bracket 5 and a spring 10 described later. On the other hand, at both ends of the upright column 2, upright barb portions 9 are provided. The semicircular curved surface portion of the holding plate 7 and the fixing bracket guide 15 of the upright 2, and the two semicircular corners of the holding plate 7 and the upright barb 9 are fixed by fixing screws 8. Further, the holding plate 7
The two corners of the semicircle are fixed to the vertical column barb portion 9 by two fixing screws 8 at one location. Therefore, the holding plate 7 and the upright 2 are securely fixed.

The fixing member 5 and the holding plate 7 are connected by a plurality of elastic members such as springs 10, and both ends of the spring 10 are fixed to the fixing member 5 and the holding plate 7 by screws 12 and screws 13. And attached to. Then, as shown in FIG. 2 and FIG.
Numerals 0 are arranged in three places in the same position on the fixing bracket 5 and the holding plate 7, respectively. Also, on the car room floor 14,
Movement prevention fittings 11 are provided at both corners inside the upright 2 and facing the upright barb 9. Therefore, when an external force is applied to the upright 2, the external force is absorbed by the expansion and contraction of the spring 10, and the movement can be stopped by the movement preventing fitting 11 even if the upright 2 moves. And
The upright 2 can be returned to the original position by the elasticity of the spring 10. Therefore, the holding bracket is not damaged.

In this embodiment, as described above, the holding plate 7 has a semicircular shape, and the side surface of the fixing member 5 facing the curved surface portion of the holding plate 7 is formed by the holding plate 7 and the fixing member 5. It is a curved surface that makes the distances equal. Therefore, if the springs 10 having the same elasticity are connected, the fixing metal 5 and the holding plate 7 maintain uniform elasticity. For this reason, uniform elasticity is maintained in both the fixture 5 and the upright 2, and the external force against the upright 2 can be quickly absorbed, and the upright 2 can be returned to the original position. Therefore, the holding bracket is not damaged. Also, as shown in FIG. 1, when springs 10 are provided at a plurality of positions at equal intervals, the fixing bracket 5 and the upright 2 can maintain uniform elasticity, absorb external force on the upright 2 quickly, and
The upright 2 can be returned to its original position. Therefore, the holding bracket is not damaged.

With the above structure, even if a trolley or the like collides with the vertical column 2 during the transportation of a load, the holding member is not damaged by the expansion and contraction of the spring 10 and the movement preventing bracket 11, and the vertical column 2 and the car door are further connected. Gap does not fluctuate.

The spring 10 only needs to have elasticity, and may be rubber, for example. In the present embodiment, the holding plate 7 has a semicircular shape. However, any shape may be used as long as the distance between the holding plate 7 and the fixture 5 is uniform.
Further, the standing pillar 2 and the fixing bracket 5 may be directly connected by the spring 10 without using the holding plate 7, and in this case, it is preferable to connect the springs having different elasticity in accordance with the interval between them.

[0020]

As described above, according to the cage entry / exit column holding fixture according to the present invention, since the fixing bracket and the side surface of the entry / exit column of the cab are connected by the elastic member, the cab floor is flexible. The standing pillar is fixed. Therefore, even if a force is externally applied to the column, the elastic member can absorb the external force and return the column to its original position without damaging the holding bracket.

Further, since the semicircular holding plate is provided between the fixing bracket and the inner surface of the cab entry / exit column, the distance between the holding plate and the fixing bracket becomes uniform. In addition, since the holding plate is fixed to at least one side of the cab door entrance / exit and the fixing bracket and the holding plate are connected by the elastic member, uniform elasticity of the fixing bracket and the holding plate is maintained. Further, both the fixing bracket and the upright can be kept uniform elasticity.

Further, even if a trolley or the like collides with the vertical column when carrying a load, the gap between the vertical column and the car door does not change due to expansion and contraction of the elastic member. Therefore, it is possible to reduce the work of replacing the holding bracket.
