Abstract

(57) [Summary] [Purpose] The objective is to improve the visibility of the upper front part of the cab and to improve the drainage of rainwater from the ceiling. [Structure] By adopting curved glass for the cab front glass 2, the positions of the pillars 1 extending from both sides are moved rearward, and the ceiling glass 4 is attached by the adhesive 5 without using the rubber cushion 3. I chose

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the upper front part of the cab structure of a construction vehicle.

[0002]

[Prior Art]

 Conventionally, the glass of the cab is attached with rubber cushions by using the pillars at each corner as shown in Figs. 3 is an overall perspective view, and FIG. 4 is a sectional view taken along line AA of FIG. 3, where a is a front glass, b is a ceiling glass, c is a rubber cushion, and d is a pillar.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional structure has problems such as that the column at the upper front obstructs the view, and the rubber attached to the ceiling glass interferes with the drainage of rainwater, especially during the upward operation of a crane truck. Was there.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned problems, and the upper part of the front of the cab has a curved structure, and the positions of the pillars extending from both sides of the cab are moved rearward to improve the visibility and to mount the Arai glass. Adhesive type with a structure that allows good drainage.

[0005]

[Action]

 Since this invention adopts the above-mentioned configuration, the view above the front surface is good, the operation is easy, and rainwater, dust, dead leaves, etc. do not collect due to the change in the method of mounting the ceiling glass, and drainage is possible. Will be done.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entire cab of a construction vehicle according to the present invention. The pillar 1 is moved rearward by using curved glass for the front glass 2 with a curved structure near both sides of the cab where the pillar 1 is mounted. The front view is good and the work on the front is easy and the work can be performed safely.

FIG. 2 shows a cross section taken along the line AA of FIG. 1, but the curved surface portion of the front glass 2 is fixed to the column 1 via a rubber cushion 3. However, the ceiling glass 4 does not use a rubber cushion but has a structure in which it is fixed to the pillar 1 using an adhesive 5. Therefore, the rainwater that has fallen on the ceiling glass will not be collected and will be drained through the side of the cab.

[0008]

[Effect of the device]

 The present invention is constructed as described above, and the cab has a good view of the front upper part without being obstructed by the pillar, so that safe upward work can be performed.

[Brief description of drawings]

FIG. 1 shows an overall perspective view of a cab according to the present invention.

FIG. 2 shows a cross section taken along the line AA of FIG.

FIG. 3 shows an overall perspective view of a conventional cab.

FIG. 4 shows a cross section taken along the line AA of FIG.
