JPH0744491Y2 - Industrial vehicle cabin - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cabin mounted on an industrial vehicle such as a forklift.

[Conventional technology]

As shown in FIG. 6 and FIG. 7, there is known a cabin in which a door 3 is attached to a cabin body 2 mounted on a vehicle body 1 by a hinge 4 so as to be openable and closable. 5 is a counterweight.

[Problems to be solved by the device]

Since the door 3 of the cabin rotates to the side of the vehicle body, when the width of the passage 6 is narrow as shown in FIG. 8, the door 3 interferes with the rack 7 on the side of the passage 6 and cannot be opened or closed sufficiently. .

In order to solve this, the door 3 may be opened and closed along the cabin body 2 so as to be slidable in the front-rear direction, but when the door 3 is slid backward as shown by a dashed line in FIG. Since the rear part of the cabin body 2 projects rearward more than the rear part, the front part and the rear part of the door 3 cannot be supported and the door 3 is cantilevered. Therefore, an excessive force acts and the door 3 comes off. I have something to do.

Then, this invention aims at providing the cabin of the industrial vehicle which was able to solve the above-mentioned subject.

[Means and Actions for Solving the Problems]

At the front of the vehicle body 10, a cabin 13 having a door 12 slidably mounted on the side surface of a cabin body 11 is attached, and a counterweight 14 is provided at the rear of the cabin 13 of the vehicle body 10.
The door 12 is attached movably in the front-rear direction along one side surface of the counterweight 14, and a guide groove 15 facing the front-rear direction is formed on one side surface of the counterweight 14, and the guide groove 15 extends in the front-rear direction. A guide rail 16 having a groove 18 is provided slidably in the front-rear direction, and a support mechanism 17 slidable in the front-rear direction along the groove 18 of the guide rail 16 is connected to the rear portion of the door 12 of an industrial vehicle. cabin.

This allows the support mechanism 17 to slide when the door 12 slides backward.
Slide backward along the groove 18 of the guide rail 16, and when the door 12 is further slid, the guide rail 16 slides backward along the guide groove 15 of the counterweight 14,
The rear portion of 12 can be supported while slidingly guided by counterweight 14.

〔Example〕

As shown in FIG. 1, at the front of the vehicle body 10, the cabin body 11
A cabin 13 having a door 12 is attached to the cabin, and a counterweight 14 is attached to the rear of the cabin 11.

A guide groove 15 extending in the front-rear direction is formed on a side surface 14a of the counterweight 14, and a guide rail 16 is provided in the guide groove 15 so as to be slidable back and forth, and a support mechanism 17 slidable along the guide rail 16 is provided. To the lower rear part of the door 12,
Support mechanism 17, guide rail 1 when sliding back and forth
6, the guide groove 15 can support the lower rear part of the door 12.

The guide groove 15 has a U-shaped cross section which is continuous from the front surface of the counterweight 14 to the rear surface thereof.
Is slidably fitted along the guide groove 15, and a groove portion 18 having an opening on the front surface is formed in the front-rear direction. The support mechanism 17 has the guide roller 20 on the cross member 19 as shown in FIG. Provided,
Further, the link 21 is connected by a vertical pin 22 so as to be rotatable in the horizontal plane direction, and the guide roller 20 thereof is a groove portion of the guide rail 16.
A link 21 is slidably faced, and a link 21 is rotatably connected to a support portion 23 of the door 12 in a horizontal plane direction.

Then, when the door 12 is closed, the guide rail 16 and the support mechanism 17 slide forward as shown in FIG. 4 (a), and when the door 12 is slid backward and opened, as shown in FIG. 4 (b). Since the guide rail 16 slides rearward along the guide groove 15 and the support mechanism 17 slides rearward along the groove 18 of the guide rail 16, the rear portion of the door 12 is supported by the support mechanism 17, the guide rail 1.
6, can be supported while sliding guide by the guide groove 15 of the counterweight 14.

Also, when the door 12 is closed, the guide rail 16
It is safe because it is housed in 15 and does not project backward from the counterweight 14.

Further, since the link 21 rotates in the horizontal direction, when the width of the counterweight 14 is wider than that of the cab 13 as shown in FIG.
The door 12 can be swung outward so as not to interfere with the counterweight 14.

[Effect of device]

When the door 12 is slid backward, the support mechanism 17 slides backward along the groove portion 18 of the guide rail 16, and when the door 12 is further slid, the guide rail 16 slides backward along the guide groove 15 of the counterweight 14. Therefore, the rear portion of the door 12 can be supported while being slidably guided by the counterweight 14.

Further, since the support mechanism 17 is slidably provided in the groove portion 18 of the guide rail 16 provided in the guide groove 15 of the counterweight 14, the guide rail 6 is guided by the guide groove 15 of the counterweight 14.
Since the door 12 can be stroked by the sum of the sliding distance and the sliding distance of the support mechanism 17 with respect to the groove portion 18 of the guide rail 16, it is possible to support the stroke longer than the front-rear width of the counterweight 14, and When the door 12 is closed, the guide rail 16 can be housed in the counterweight 14 so as not to project backward, which is safe.
