Abstract

(57) [Summary] [Purpose] To provide an inexpensive cab for construction machinery with a good appearance. In an operator's cab of a construction machine substantially entirely formed by a curved line, both sides of a roof 1a of a driver's cab body 1 are formed by curved bulging portions 1b matching the overall curve, and a central portion of the roof 1a Is a flat surface, and a flat transparent plate 4 is fitted to the skylight 3 opened in the flat surface,
Since inexpensive flat glass can be used for the skylight 3, the price can be reduced, and since it is not necessary to separately provide the raining lip 1c that spoils the appearance, the appearance of the entire cab body 1 is improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cab of a construction machine such as a crane truck.

[0002]

[Prior art]

 Conventional construction machines such as mobile cranes are provided with skylights fitted with transparent plates on the roof of the cab in order to facilitate work in high places by working machines. In recent years, in order to improve the appearance of construction machinery, many curves have been incorporated into the cab design, and a curved surface as shown in Fig. 1 is also used for the roof b of the cab a.

[0003]

[Problems to be solved by the device]

 Therefore, in the conventional driver's cab a, the curved glass d fitted to the curved surface of the roof b is fitted to the skylight c opened to the roof b, which causes a problem of increased cost. Rained lips e, which serve as rain catches, are provided on both sides of the roof b in a straight line. However, the rained lips e do not match the curve of the roof b and the like, which may cause the appearance of the cab a to deteriorate. ing. The present invention has been made in view of such circumstances, and an object thereof is to provide a cab of a construction machine having a good appearance at low cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is to construct a driver's cab of a construction machine that is almost entirely formed by a curve, and forms both sides of the roof of the operator's cab main body with curved bulging parts that match the entire curve. The central part of the roof is formed into a flat surface, and a flat transparent plate is fitted to the skylight that opens in this flat surface.

[0005]

[Action]

 With the above-mentioned configuration, inexpensive flat glass can be used for the skylight, so that the cost can be reduced, and since the bulging portions on both sides of the roof double as the rain lips, it is not necessary to provide the rain lips that impair the appearance of the entire cab body.

[0006]

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. 3 is a plan view of the operator's cab, FIG. 4 is a side view of the roof portion, FIG. 5 is a perspective view of the roof portion, and FIG. 6 is a sectional view taken along line BB of FIG. In these figures, 1 is a driver's cab body of a construction machine such as a crane truck, which is formed into a rounded box-like shape. A front window 2 is provided on the front side and an openable / closable door 5 is provided on the side surface. Has been.

The roof 1a of the cab main body 1 is formed in a curved shape on the front side and the rear side as shown in FIG. 4, and the roof 1a continuing to these curves is almost entirely flat. A rectangular skylight 3 is opened on the flat roof 1a. A transparent plate 4 made of flat glass is fitted on the skylight 3 so as to be flush with the roof 1a.

On the other hand, on both sides of the roof 1a, bulging portions 1b are formed as shown in FIG. 5 so that the roof 1a looks like a curve when the roof 1a is viewed from the side. These bulging portions 1b are formed in a curve that is continuous with the curves of the front and rear sides of the roof 1a so that there is no discomfort, and the rain that has fallen on the roof 1a is in front of and behind the roof 1a. It also functions as a rain lip 1c that prevents the flow toward both sides of the cab main body 1 by flowing out in the direction.

The operation will be described below. The cab body 1 configured as described above is adapted to be used by being mounted on the vehicle body of a construction vehicle such as a crane vehicle, and it can be used by using a working machine such as a crane. When performing work at a high place, the work state can be seen clearly from the skylight 3, which enables safe and efficient work at a high place.

Even if it rains during work, raindrops that have fallen on the roof 1a are discharged in the front-rear direction of the roof 1a by the bulging portions 1b that also function as rain drip 1c on both sides of the roof 1a. Since it does not drip to both sides, when getting on and off the driver's cab main body 1, it is less likely to get wet with raindrops drip from the roof 1a.

[0011]

[Effect of device]

 As described in detail above, this invention forms both sides of the roof of the driver's cab main body with curved bulging parts according to the curve of the entire driver's cab main body, and the central part of the roof is a flat surface with a skylight on this flat surface. Since it is opened, inexpensive flat glass can be used for the transparent plate that fits into the skylight, and the cost can be reduced. In addition, the appearance of the roof viewed from the side of the driver's cab body matches the curve of the entire driver's cab, and the bulging part also functions as a rain lip, so it is necessary to provide a separate rain lip to create a strange feeling. This makes it possible to further improve the overall appearance of the cab.
