Description

  The present invention relates to a vehicle including a driving cabin, a transparent window plate for enabling a rear side of the driving cabin to be visible, and a movement guide mechanism that supports the transparent window plate in a movable manner.

As described above, when the driving cabin, the transparent window plate for enabling the rear side of the driving cabin to be visible, and the movement guide mechanism that supports the transparent window plate so as to be movable, the driving cabin is provided. It can be conveniently used in view of the rear side of the driving cabin and the ability to ventilate the cabin.
As a vehicle adopting such a structure, a technique shown in the following [1] is conventionally known.
[1] The rear glass of the driving cabin is configured to rotate with a hinge provided at the upper end portion as a fulcrum and to open the lower end side toward the rear side (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2014-159195 (see paragraph “0016”, FIG. 5 and FIG. 9)

In the vehicle having the above-described conventional structure, the rear glass, which is a transparent window plate, can be opened rearward by grasping the operation lever provided on the lower end side thereof. Therefore, it is useful in that it is easy to ventilate the operating cabin or to lean backward from the cabin and look into the lower rear of the cabin where the connected working device or the like is present.
However, in this structure, since the rear glass rotates with the hinge provided at the upper end as a fulcrum, a relatively large empty area for allowing the rear glass to swing is provided on the rear side of the rear glass. It is necessary to secure.
Therefore, in the state where some other object itself or an operation area of another object exists near the rear side of the rear glass, it is difficult to open the rear glass, so there is room for improvement in this respect.

  The present invention can reduce the degree of protrusion to the outside of the driving cabin during the opening and closing operation of the transparent window plate, and can perform the opening and closing operation of the transparent window plate with less risk of being obstructed by the presence of other objects on the rear side of the driving cabin. Is something to try to do.

The vehicle according to the present invention includes a driving cabin, a transparent window plate for allowing a rear side of the driving cabin to be visible, and a movement guide mechanism that supports the transparent window plate so as to be movable. A mechanism includes a guide rail portion provided across a rear surface portion and an upper surface portion of the operation cabin, and a plurality of guided bodies guided by the guide rail portion, and the plurality of guided bodies are A plurality of guided bodies are provided at predetermined intervals in the guide direction of the guide rail portion, and the plurality of guided bodies move while receiving the guide action by the guide rail portion at the plurality of locations in the guide direction. be configured to, the movement guide mechanism, the transparent window plate, and a rear closure position located rear surface portion of the driving cabin, the rear opening which is located on an upper surface of the driver cabin The transparent window plate is erected along the rear surface portion of the operation cabin at the rear closed position, and along the upper surface portion of the operation cabin at the rear open position. It is configured to change the posture in accordance with the slide movement to the lying down posture, and the interval between the guided bodies at the plurality of locations in the guide direction is larger than the length of the transparent window plate in the guide direction. It is in the point set short .

According to the present invention, the transparent window plate is not simply oscillated by using one fixed fulcrum existing at the upper part of the operating cabin as the oscillating fulcrum, but along the rear surface portion and the upper surface portion of the operating cabin. The posture is changed.
That is, the transparent window plate has a standing posture that stands up along the rear surface portion of the driving cabin at the rear closed position and a lying posture that falls down along the upper surface portion of the driving cabin at the rear opening position. The posture is changed as it slides over the upper surface. Therefore, the transparent window plate can be opened and closed with a reduced degree of protrusion to the outside of the operation cabin, compared to the case where the operation is performed with the fixed fulcrum at the upper part of the operation cabin as the oscillating fulcrum. There is an advantage that it is easy to avoid interference with other objects on the rear side of the.

Further, the transparent window plate slides and moves by a moving guide mechanism including a guide rail portion provided over the rear surface portion and the upper surface portion of the operation cabin, and a plurality of guided bodies guided by the guide rail portion. While being opened and closed.
Thus, when the movement guide mechanism includes a plurality of guided bodies, for example, in the case of a structure that includes a single guided body and slides, the transparent guide plate has a single guided body during the sliding movement. Although there is a possibility that the posture is not stable due to shaking with the body as a fulcrum, it is easier to perform an opening / closing operation while keeping the slide movement posture of the transparent guide plate in a stable state as compared with the structure of such a structure.

Furthermore, if the distance between the guided bodies at a plurality of locations in the guide direction is set shorter than the length of the transparent window plate in the same direction, the degree to which the transparent window plate enters the interior space of the driving cabin during the sliding movement is set. Can be reduced.
That is, when one guided body is located on the rear surface portion of the operating cabin and the other guide member is located on the upper surface portion of the operating cabin, the guided bodies at the plurality of locations are guided. Part of the transparent window plate along the line connecting the bodies tends to partially enter the cabin of the driving cabin during the sliding movement, but the spacing between the guided bodies at the multiple locations is narrow Therefore, the degree of entry is relatively small.

  In the present invention, it is preferable that the guided body is provided in a position corresponding to an upper half portion of the transparent window plate in a standing posture at the rear closed position in the transparent window plate.

  By providing this configuration, the transparent window plate is provided with a guided body in the upper half thereof. For example, the transparent window plate is transparent as in the case where the guided body is provided in the lower half portion of the transparent window plate. It is easy to avoid a situation in which the window plate protrudes greatly to the upper side of the operation cabin, and the arrangement range of the guide rail portion can be shortened.
