Abstract

A cabin includes: a panel disposed on a side of an operator seat, the panel including: a plurality of cross members extending in a first direction; and a plurality of transverse members intersecting with the plurality of cross members each other and extending in a second direction; a glass panel disposed on a side of the panel; a window frame disposed on the glass panel; a window panel disposed on the window frame, the window panel being configured to move in the first direction or in the second direction; a projecting member disposed on a side of the window panel, the side being an identical side to the operator seat, the projecting member being configured to move together with the window panel; and a guide portion configured to accept insertion of the projecting member and to limit a moving distance of the window panel.

First claim

What is claimed is:

1. A cabin comprising:
a panel disposed on a side of an operator seat arranged in the cabin, the panel including:
a plurality of cross members extending in a first direction;
a plurality of transverse members intersecting with the plurality of cross members and extending in a second direction; and
a frame member configured to connect between end portions of the cross members and between end portions of the transverse members;

a glass panel disposed on a side of the panel, the side being opposite to the operator seat;
a window frame disposed on the glass panel;
a window panel disposed on the window frame, the window panel being configured to move in the first direction or in the second direction;
a projecting member disposed on a side of the window panel, the side being an identical side to the operator seat, the projecting member being configured to move together with the window panel in the first direction or in the second direction; and
a guide portion configured to accept insertion of the projecting member and to limit a moving distance of the window panel,
wherein the glass panel includes a rim forming an opening that is opened and closed by movement of the window panel,
wherein the window frame forms a second opening corresponding to the opening formed by the rim, supports the window panel, and allows the window panel to move,
and wherein the guide portion is constituted of the cross members and the transverse members and is arranged behind the opening and the second opening.

2. The cabin according to claim 1 , wherein
the window frame is disposed on a side of the glass panel, the side being opposed to grilles formed of the plurality of cross members and the plurality of transverse members, and includes:
an upper frame portion forming an upper rim portion of the second opening and extending further backward than the opening and the second opening; and
a lower frame portion forming a lower rim portion of the second opening and extending further backward than the opening and the second opening, and

the window panel closes the opening and the second opening by moving forward in the window frame, and opens the opening and the second opening by moving backward in the window frame.

3. The cabin according to claim 1 , comprising:
a front panel arranged in front of the operator seat; and
a rear panel arranged behind the operator seat,
wherein the panel has:
a front portion located on a side of the front panel; and
a rear portion located on a side of the rear panel,

wherein the opening is arranged on the front portion of the panel,
and wherein
the guide portion is disposed on a position corresponding to the rear portion of the panel.

4. The cabin according to claim 1 , comprising:
a frame member forming an entrance opening, the frame member being disposed forward of the operator seat; and
an operation member disposed on a corner portion between the panel and the frame member forming the entrance opening.

5. A cabin comprising:
a panel disposed on a side of an operator seat arranged in the cabin, the panel including:
a plurality of cross members extending in a first direction;
a plurality of transverse members intersecting with the plurality of cross members and extending in a second direction; and
a frame member configured to connect between end portions of the cross members and between end portions of the transverse members;

a glass panel disposed on a side of the panel, the side being opposite to the operator seat;
a window frame disposed on the glass panel;
a window panel configured to move along the glass panel;
a projecting member disposed on a side of the window panel, the side being an identical side to the operator seat, the projecting member being configured to move together with the window panel; and
a guide portion configured to accept insertion of the projecting member and to limit a moving distance of the window panel,
wherein the glass panel includes a rim forming an opening that is opened and closed by movement of the window panel,
wherein the window frame forms a second opening corresponding to the opening formed by the rim, supports the window panel, and allows the window panel to move,
and wherein the guide portion is constituted of the cross members and the transverse members and is arranged behind the opening and the second opening.

6. The cabin according to claim 5 , wherein
the window frame is disposed on a side of the glass panel, the side being opposed to grilles formed of the plurality of cross members and the plurality of transverse members, and includes:
an upper frame portion forming an upper rim portion of the second opening and extending further backward than the opening and the second opening; and
a lower frame portion forming a lower rim portion of the second opening and extending further backward than the opening and the second opening, and

the window panel closes the opening and the second opening by moving forward in the window frame, and opens the opening and the second opening by moving backward in the window frame.

7. The cabin according to claim 5 , comprising:
a front panel arranged in front of the operator seat; and
a rear panel arranged behind the operator seat,
wherein the panel has:
a front portion located on a side of the front panel; and
a rear portion located on a side of the rear panel,

wherein the opening is arranged on the front portion of the panel,
and wherein
the guide portion is disposed on a position corresponding to the rear portion of the panel.
