Description

  The present invention relates to a cab storage box for a construction machine, and more particularly to a cab storage box that secures the field of view of an operator.

  Conventionally, the cab of this type of construction machine, such as a hydraulic excavator, has a large glass window area to ensure the operator's view, and the front surface is almost entirely from the upper edge to the floor surface. The door on one side has a wide glass window. Further, as shown in FIGS. 6 to 8, the other side surface is provided with a glass window 4 in the lower half in addition to the glass window 3 in the upper half. Alternatively, a single large glass window 5 may be attached.

  Here, when the operator's portable items and optional parts are stored in the cab of this type of construction machine, the storage box 1 having an opening at the top is formed on the inner panel of the cab formed of an opaque material such as metal or resin. 2 is attached. However, as described above, since the glass window occupies a large area in the cab, the inner panel 2 has a limited area, and it is difficult to secure an installation space for the storage box.

In order to solve this problem, the applicant of the present application has proposed a storage box that is directly fitted into a window hole using a rubber seal for attaching a window glass (see Patent Document 1).
JP 2000-247185 A (pages 1 to 3, FIGS. 1 to 4).

  In the invention described in Patent Document 1, the storage box is attached to the window hole on the side surface of the cab. Therefore, even in a construction machine where the area of the inner panel such as metal or resin is limited, the installation space for the storage box in the cab Can be secured.

  However, it was necessary to remove the glass window when installing the storage box, and the installation work was complicated.

  Therefore, even when the space of the inner panel is small, there arises a technical problem to be solved for installing the storage box in the cab without disturbing the view of the glass window, and the present invention solves this problem. For the purpose.

  The present invention has been proposed in order to achieve the above object, and the invention according to claim 1 is a construction machine provided with a storage box having an upper opening inside a cab, inside a glass window. Provided is a cab storage box for a construction machine in which plates are arranged with a constant interval and the side or lower portion of the plate is fixed to an inner panel.

  Since the glass window and the plate are arranged in parallel at a constant interval, this gap portion having an upper opening serves as a storage space.

  The invention according to claim 2 provides a cab storage box for a construction machine, which is provided at a lower position inside the glass window.

  Since the storage box is at the lower position of the glass window, the operator can visually recognize the outside of the glass window through the plate of the storage box from obliquely above.

  According to the first aspect of the present invention, since the plate is arranged inside the glass window with a certain interval, and the side or lower portion of the plate is fixed to the inner panel, this gap portion with the upper portion opened is accommodated. Even when the space of the inner panel is small, it is possible to store the operator's portable items and optional parts.

  According to the second aspect of the present invention, since the storage box is provided at the lower position inside the glass window, the outside of the glass window can be visually recognized without obstructing the view of the operator.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows a hydraulic excavator 10 as an example of a construction machine, and an upper swing body 13 is mounted on a lower traveling body 11 via a swing mechanism 12 so as to be rotatable. The upper swing body 13 is provided with a cab 14 on one front side thereof, and a boom 15 is attached to the front center portion so as to be able to be raised and lowered. Further, an arm 16 is attached to the tip of the boom 15 so as to be rotatable up and down, and a bucket 17 is attached to the tip of the arm 16.

  As shown in FIGS. 1 and 2, a door 18 is detachably mounted on the left side surface of the cab, and an upper glass window 19a is provided in the upper half portion of the door 18, and a lower glass window is provided in the lower half portion thereof. 19b is provided. Console boxes 21 and 22 are arranged on the left and right sides of the driver's seat 20, and operation levers 23 and 24 are attached to the front upper portions of the respective console boxes 21 and 22.

  The front surface of the cab 14 is secured by a large area upper glass window 25 and a foot lower glass window 26 to ensure a wide front view. An upper glass window 27 and a lower glass window 28 are also provided on the right side surface of the cab 14.

  As shown in FIGS. 2 and 3, the lower glass window 28 on the side surface is attached to an opening hole of the inner panel 29 via a rubber seal R, and the inner panel 29 projects to the indoor side of the cab 14. Then, the plate 30 is arranged with a certain distance from the lower glass window 28, and the side portion 30 a and / or the lower portion 30 b of the plate 30 is fixed to the inner panel 29. Since the glass surface of the lower glass window 28 and the plate 30 are arranged in parallel with a certain distance, the gap 31 having an upper opening is a storage space, and a storage box 32 is formed.

  Thus, the operator's portable items and documents can be inserted and stored in the gap 31 of the storage box 32. The plate 30 may be made of a transparent or translucent material, but is not necessarily limited thereto. Even when a plate 30 made of an opaque material is used, the operator can visually recognize the outside of the lower glass window 28 through the plate 30 of the storage box 32 from above as shown by an arrow A in FIG.

  As shown in FIG. 4, there is a case where a single large-area glass window 33 that is not divided vertically is attached to the right side surface of the cab 14 to further improve the visibility. Then, the plate 30 is disposed at a lower position on the inner side of the glass window 33 with a certain distance from the glass window 33, and the side portion 30 a and / or the lower portion 30 b of the plate 30 is fixed to the inner panel 29. Also in this case, since the glass surface of the glass window 33 and the plate 30 are arranged in parallel with a certain distance, the gap portion 31 opened at the top serves as a storage space, and the storage box 32 is configured. Is done.

  Thus, in any of the glass windows of FIGS. 2 to 4, as shown in FIG. 5, the storage box 32 is installed at the lower side of the operator. Operator's portable items and optional parts can be stored without obstructing the field of view.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
