Description

  The present invention relates to an industrial vehicle in which a weight is attached to a vehicle body.

  Conventionally, in an industrial vehicle such as a forklift, a weight is attached to a vehicle body to ensure stability. However, when the weight is attached, there is a problem that the entire length of the vehicle becomes long and the turning radius becomes large. Therefore, as described in Patent Literature 1 and Patent Literature 2, it is considered to suppress an increase in the turning radius while ensuring stability by using a weight having a shape extending upward.

  Further, the weight may be formed of a casting, but in this case, it is difficult to obtain a good appearance, and there is a problem that it takes time and effort for processing and painting. Therefore, for example, as described in Patent Document 3, it is considered to attach a cover to a casting weight. Further, the weight may contain a controller for controlling the vehicle, as described in Patent Document 4, for example.

  Now, as described in Patent Document 3, when the cover is attached using the weight suspension hole, the cover can be attached and detached relatively easily. However, there is a problem that it is somewhat unsuitable for attaching with high accuracy, and the portion covered by the cover is not necessarily attractive because it has corners and plugs that close the suspension holes. For example, as described in Patent Document 4, if the support member is fixed to the weight and the cover is attached to the support member, the cover can be attached with high accuracy and the appearance is also good. it can. However, it takes extra work and labor to fix the support member to the weight.

  Further, in a vehicle in which the head guard is attached to the vehicle body, as described in Patent Document 1 and Patent Document 3, for example, it is described in Patent Document 2 rather than arranging the head guard column on the outside or front side of the weight. As shown in the figure, it is possible to improve the appearance by arranging the support pillars inside the weight. However, if the struts are simply arranged inside, there is a problem that it becomes difficult to attach and remove the struts due to weights and the like.

  An object of the present invention is to easily improve the appearance of a vehicle and to make it easier to attach and remove a head guard.

Further, since the protruding portion is covered with the cover member, the protruding portion can be protected, and a good appearance of the protruding portion can be obtained without any further effort.

Further, in the above configuration, in the case where a head guard provided with a pedestal member standing at the rear of the vehicle body and a ceiling member supported by the pedestal member and covering the upper side of the vehicle body is provided, Is provided with an opening that opens upward in the projecting portion and that is recessed forward, and into which the pedestal member can be inserted, and the cover member covers at least the opening from the front side.
In addition, that the opening is formed in a concave shape forward means that there are portions protruding forward from the back surface (rear surface) of the opening on both sides of the opening, and the opening is left or right. It is that it is not open to the direction.

  In this way, the weight and the storage chamber do not interfere with the attachment and detachment of the pedestal member to the vehicle body, and the pedestal member can be reliably fixed to the vehicle body. In addition, since the pedestal member is disposed inside the weight and the opening of the protruding portion is covered with the cover member, a good appearance can be obtained.

  Further, in the above configuration, the support member is provided so as to be disposed in the opening when the weight is attached to the vehicle body, and the cover member and the leg are attached to the support member in the opening. Each of the column members can be fixed.

  In this way, the cover member and the pedestal member can be securely fixed to the vehicle body, and the cover member and the head guard can be attached and detached without being obstructed by the storage chamber. . Furthermore, the fixing part of the support member and the pedestal member can be hidden by attaching the cover member, and the opening is opened by removing the cover member, so the support member and the pedestal member can be easily fixed. Can be performed or unlocked.

  Still further, in the above configuration, the weight may include a storage chamber in which the device can be stored in at least the protruding portion.

  In this way, the apparatus can be housed in the weight while suppressing an increase in weight. In addition, since the device is stored at a higher position than the case where the weight has a storage chamber but not in the protruding portion, the worker can take the device into and out of the storage chamber in a relatively easy posture. become.

  As described above, according to the present invention, a good appearance can be obtained by carrying out relatively easily without processing the weight for attaching the cover member. Further, in the present invention, the head guard can be obtained while obtaining a good appearance by providing an opening into which the head guard pedestal member can be inserted in the protruding portion of the weight and fixing the pedestal member within the opening. Can be easily attached and detached.
