JPH05585U - Construction vehicle cabin - Google Patents

Abstract

(57) [Summary] [Purpose] The objective was to reduce the turning radius of cab-turnable vehicles. [Structure] The curved surface structural member 1 was adopted for the rear surface shape of the cab, and the protruding portion at the time of turning was reduced to reduce the turning radius.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to the rear end shape of the cab structure of a construction vehicle.

[0002]

[Prior Art]

 Conventionally, as shown in Fig. 3, the rear end shape of the cab has been a flat shape where the side surface and the rear surface intersect. In the figure, a is a front glass, b is a ceiling glass, c is a pillar, and d is a corner.

[0003]

[Problems to be solved by the device]

 The conventional cab has a problem that the total length of the cab becomes long, and particularly in the case of a cab turning vehicle such as a crane truck, the turning radius becomes large and the performance of the vehicle is deteriorated.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned problems. In addition to providing a sufficient space inside the cab device, a curved surface is formed on the rear surface so that the turning radius can be reduced, and the corner pillars are eliminated to improve visibility. A cab structure that secures a small turning radius is adopted.

[0005]

[Action]

 Since the present invention adopts the above-mentioned configuration, the turning radius at the time of turning can be reduced while ensuring the visibility and space in a vehicle capable of turning in a cab, which enables a cab structure with a small turning ability.

[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. Reference numeral 1 is a curved member, 2 is a front glass, 3 is an entrance / exit door, 4 is a window, 5 is a ventilation hole, and 6 is a ceiling glass. Since the rear plate and the side plate of the cab are joined by the curved member 1, in the top view of the cab shown in FIG. The curved radius 1 allows the radius to be determined by the distance between the centers with a sufficiently small radius.

[0007]

[Effect of the device]

 This invention is made as described above, and by forming the rear surface with a curved surface, the protruding portion at the time of turning is reduced, the cab has a small turning radius, and a structure with excellent operability can be provided. .

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

FIG. 2 shows a top view of the cab of FIG.

FIG. 3 shows a right side view of the cab of FIG.

4 shows a rear view of the cab of FIG.

FIG. 5 shows an overall view of a conventional cab.
