[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabin of a construction machine or the like, and more particularly to a cabin having an adhesive glass structure.

[0002]

2. Description of the Related Art FIG.
As shown in (a) and (b), when the glass 22 is attached to the window 21, the glass 22 cannot be attached directly, so that the end is fitted into the groove of the H-shaped rubber 23 or the S-shaped rubber 24. I have to.

[0003]

However, the conventional cabin has the following problems including processing. Poor precision of the sheet metal, rubber, and glass constituting the cabin body may cause rain leakage and the like. The H-shaped rubber and the S-shaped rubber have a poor visibility due to their wide width, and also have a very poor impression in terms of design because the rubber projections appear on the outer surface. Desorption of glass requires specialized techniques, requires great power, and is difficult to automate. In particular, since a cabin for construction equipment has large vibration and impact, as shown in FIG. 6, many reinforcing members 26 such as ribs are welded to the inside of the outer plate 25. Since it comes out and becomes unsightly, it is necessary to finish it with a grinder. The grinder processing takes time and also causes pollution such as dust and noise.

In view of the foregoing, the present invention provides a cabin having an adhesive glass structure that improves visibility and appearance, eliminates grinder finishing, and improves water resistance and productivity. The purpose is to eliminate the disadvantages.

[0005]

According to the present invention, as a means for solving the above problems, the cabin is constituted by a first outer panel for an upper surface, glass for a side surface, and second outer panels for a middle and a lower side. The first outer panel, which is a boundary with the glass, is receded inward to form a glass bonding surface, and the outside of the second outer panel is used as a bonding surface, and the glass surface attached to both bonding surfaces is the first outer panel surface. It is characterized by being the same as.

[0006]

According to the above construction, since the sheet metal portion of the outer panel or the like is not exposed on the outer surface of the cabin, trace finishing by welding is not required, and the cabin manufacturing operation is improved.

1 is a perspective view showing an external appearance of an embodiment of a cabin having an adhesive glass structure according to the present invention, and FIG. 2 is a sectional view of FIG.

As shown in FIGS. 1 and 2, the cabin 1 of the present invention comprises a first outer panel 2 for the upper surface, a glass 3 for the side, and second outer panels 4 and 5 for the middle and lower sides. First outer panel 2 serving as a boundary with glass 3
Of the glass 3 is formed by inwardly retreating the peripheral edge of the second outer panel 4, and the outer surface of the second outer panels 4 and 5 is
As a and 5a, the three surfaces of the glass attached to both the bonding surfaces 2a, 4a and 5a are the same as the first outer panel 2 surface.

That is, the cabin 1 is composed of a first outer panel 2 whose upper portion, which is a roof, is made of sheet metal and the like, and whose side surfaces are made of glass 3 (or transparent acrylic or the like). Since the second outer panels 4 and 5 and the reinforcing member 6 are inside the glass 3,
It is not visible from the outside. That is, FIG.
(A) In the case of the panel surface, the peripheral edge of the upper first outer panel 2 is in contact with the glass 3 surface so as to be attached in contact with the glass 3 surface, and the adhesive surface 2 is recessed by a desired depth.
a is formed. The inside of the bonding surface 2a is reinforced by the inner panel 7. Also, the bonding surface 2a
In the same vertical direction as the second outer panel 4, a second
The outer panel 5 is provided so that the inner surface is reinforced by the reinforcing member 6 and has adhesive surfaces 4a and 5a around the inside of the cabin 1 respectively. Therefore, the glass 3 is bonded to the bonding surfaces 2a, 4a, and 5a via the adhesive 8 and the dam 9. In this case, the bonding is performed between the outer surface of the glass 3 and the first surface.
The outer panel 2 is formed so as to be flush with the vertical plane. Then, the end face of the glass 3 and the first outer panel 2
A mall 10 is attached to the gap between the boundary and the boundary, preventing rainwater from entering the cabin 1 from the boundary, and improving the appearance. The second outer panels 4, 5
The adhesive 8 and the dam 9 are used for attachment to the glass 3 as in the upper part.

Next, in the case of FIG. 2B in which the AA section is a door surface, the door body 11 surrounding the glass 3 is made of sheet metal, and the first outer panel 2 and the second outer panel 5 form a door seal 12. Are connected via Other structures are the same as those in the case of FIG. (C), which is a BB cross section, is the same as the case of (a), and thus the description is omitted. In the case of FIG. 2 (d) having a cross section taken along the line CC, the second outer panel 4 'is curved as shown in FIG. Things are attached. In FIG. 2, the glasses 3, 3 'and the first and second outer panels 2, 4, 4 are shown.
A coating 14 is provided on the adhesive surface to which 4 'and 5 are attached.

FIG. 3 shows that the screws 1 are attached via the sheet 15 without depending on the adhesive when the glass 3 and the outer panels 2 and 5 are attached.
6 shows an embodiment in the case of stopping, and the effect is the same as in the above case. In the figure, 17 indicates a packing, and 18 indicates a seal.

FIG. 4 shows a comparison between the structure using the adhesive glass according to the present invention and the conventional H-shaped rubber and S-shaped rubber, and shows that the visibility according to the present invention is better than the conventional one. Is shown.

[0013]

As described above, in the present invention, the cabin is constituted by the first outer panel for the upper surface, the glass for the side surface, and the second outer panels for the middle and the lower side, and forms a boundary with the glass. The periphery of the first outer panel is receded inward to form a glass bonding surface, and the outside of the second outer panel is used as a bonding surface, and the glass surfaces attached to both bonding surfaces are the same as the first outer panel surface. The outer panel formed of a sheet metal does not appear on the outside, and even if a reinforcing material such as a rib is welded to the back side, it is not necessary to finish the outer surface with a conventional grinder. Also, since the outer surface is a glass surface, the outer surface is glossy, and the appearance is improved by giving a new image to the appearance. Further, the visibility is improved, and the productivity is also improved.
