Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door attachment device that is easily attached to a pillar in a building, an industrial vehicle, or the like and is easily attached and detached.

[Prior art]

Generally, in industrial vehicles such as forklift trucks, a driver's seat is provided on the vehicle frame. Further, as shown in FIG. 6, a door 10 is attached to a pillar 2 standing on the vehicle body at the entrance / exit of the driver's seat in order to prevent entry of wind and rain.

That is, the door 10 includes the shaft pins 11 and 1 provided on the upper and lower portions.
Axial holes 310 of the hinges 31 and 32 in which 2 is attached to the column 2,
Attach by inserting into 320. And the door 1
0 is pulled by pulling the pull tab 13 toward the front so that the hinge 3
It rotates around 1, 32 as an axis and is opened and closed.

[Problems to be solved]

However, since the door 10 has a window glass 15 fitted in a body 14 generally made of metal,
The weight of the door 10 itself is quite heavy. Therefore, the door 10
It is quite difficult to attach the to the column 2. That is, when the door 10 has a large shape or the mounting position of the support column 2 is high, the door 10 itself is heavy, so that the shaft pins 11 and 12 and the shaft holes 310 of the hinges 31 and 32, It is difficult to match the axis line with 320. Therefore, attaching the door 10 to the column 2 involves considerable difficulty.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a door attachment device that is easily attached to a pillar in a building, an industrial vehicle, or the like and is easily attached and detached.

[Means for solving problems]

The present invention comprises a shaft pin provided at at least two upper and lower positions of a door, and a hinge which is arranged on a column and rotatably supports each shaft pin, and the lower hinge of the hinges rotates in the vertical direction. The lower hinge of the door is inserted into the hinge with the lower hinge in a substantially horizontal direction, and then the door is erected vertically with the hinge as a fulcrum, and the other axle pin The door mounting device is characterized in that the door is mounted by inserting the key into the corresponding hinge.

In the present invention, the shaft pin is provided at at least two places on the door. For example, the shaft pins can be provided at two or more locations by adding the upper and lower parts around the center of the door, and the vicinity of the center if necessary. In the present invention, the lowermost shaft pin is called the lower shaft pin.

Also, the hinge has a shaft hole corresponding to the length and thickness of the shaft pin. The lowermost hinge at the bottom of the hinges is a substantially T-shaped hollow shaft, and the lower shaft pin is fitted in a vertical shaft hole. Then, a pin for supporting the weight of the door is inserted into the horizontal shaft hole. Further, the lower hinge is attached to the column by a locking tool such as a clamp so as to be rotatable in the vertical direction.

[Action and effect]

In order to mount the door in the present invention, the lower shaft pin of the door is inserted with the lower hinge in a substantially horizontal direction. Then, the door is erected vertically with the horizontal axis of the lower hinge as a fulcrum, and the upper shaft pin of the door is inserted into the shaft hole of the upper hinge to attach the door to the column.

As described above, the door mounting device of the present invention is designed such that the lower shaft pin and the lower hinge are pre-engaged when mounting the door mounting device.
Since the door stands upright, it is easy to install a door with a large weight and shape.

Therefore, according to the present invention, it is possible to provide a door attachment device that is easily attached to a pillar in a building, an industrial vehicle, or the like, and that is easily attached and detached.

〔Example〕

The door mounting device according to this example will be described with reference to FIGS. 1 to 5.

That is, as shown in FIG. 1, the door mounting device of the present embodiment has an upper shaft pin 17 and a lower shaft pin 19 provided at two upper and lower positions on the side surface of the main body 14 of the door 1, and the shaft pin 17 of the column 2. , Upper hinges 4 provided at positions corresponding to 19,
It consists of a lower hinge 5.

The door 1 is attached to the pillar 2 near the entrance / exit of the driver's seat of the forklift truck. And the door 1 has a main body 14
And the window glass 15 attached to the upper center. Further, the main body 14 has, on its side surface, an upper shaft pin 17 suspended from a bracket 16 provided on the upper side, and a lower shaft pin 1 suspended from a bracket 18 provided on the other lower side.
Have 9. Further, the door 1 has a pull tab 13 at a lower portion of the center front thereof. The main body 14 is made of a metal rectangular parallelepiped having a front side surface whose front side A is inclined. The length of the lower shaft pin 19 is approximately twice the length of the upper shaft pin 17.

Next, the upper hinge 4 has a shaft hole 41 in the up-down direction at a substantially central portion, and the mounting plates 42 on both left and right sides of the shaft hole 41 have screw holes 420, respectively.

On the other hand, as shown in FIG. 2, the lower hinge 5 has a T-shape composed of a vertical tubular body 51 and a horizontal tubular body 52. The vertical cylindrical body 51 has a shaft hole 510,
The horizontal tubular body 52 has a shaft hole 520. Then, in the lower hinge 5, the horizontal tubular body 52 is attached to the support column 2 via a locking tool 7 such as a clamp. The locking tool 7
Has a semicircular arc-shaped protrusion 72 at the substantially center thereof.
The cylindrical body 52 is rotatably gripped at 2, and a screw is inserted into the screw hole 71 and fixed to the column 2. Further, a detachable horizontal pin 6 is inserted in the shaft hole 520 of the cylindrical body 52 in the horizontal direction. In addition, in the figure,
Reference numeral 61 is a handle of the horizontal pin.

Since the door 1 of this example is configured as described above, it has the following effects.

That is, the door 1 of this example is attached to the column 2 of the entrance / exit of the forklift truck by the procedure shown in FIGS.

First, as shown in FIG. 3, the upper and lower cylindrical bodies 51 of the lower hinge 5 are placed in a substantially horizontal direction.

Next, the lower shaft pin 19 of the door 1 is inserted into the shaft hole 510 of the cylindrical body 51. After that, as shown in FIG.
The door 1 is erected vertically with the horizontal tubular body 52 of the lower hinge 5 as a pivot.

Next, attach the upper shaft pin 17 of the door 1 to the shaft hole 4 of the upper hinge 4.
Align with 1 axis. Then, as shown in FIG. 5, the handle 61 of the horizontal pin 6 in the lower hinge 5 is pulled out in the C direction.

As a result, the lower shaft pin 19 goes deeper into the cylindrical body 51, and the upper shaft pin 17 moves into the shaft hole 41 of the upper hinge 4.
Fit inside. Therefore, the door 1 is lowered downward, and is left in a normal position.

Therefore, the door 1 can be easily attached to the column 2.

On the other hand, when the door 1 is repaired, or when it is to be removed during a hot summer season, the procedure is the reverse of the above-described installation of the door 1. That is, as shown in FIG. 5, the door 1 is lifted in the D direction and the horizontal pin 6 is fitted into the shaft hole 520. As a result, as shown in FIG.
Comes off the upper hinge 4. Then, as shown in FIG. 3, after the door 1 is tilted in the horizontal direction, the lower shaft pin 19 is pulled out from the shaft hole 510 and the door 1 is removed from the column 2.

Therefore, according to this example, it is possible to provide a door attachment device that is easy to attach to a pillar in an industrial vehicle such as a forklift truck and is easy to attach and detach.

The door attachment device of this example has a horizontal hinge 6 on the lower hinge 5.
The case where the horizontal pin 6 is inserted into the upper hinge 4 is shown.
It is also possible to adopt a configuration in which is inserted.
