Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cab roof of a truck such as a truck or a tractor. More specifically, the present invention relates to a cab roof in which a decorative garnish on a front portion of a roof is configured to be capable of undulating so that the garnish has a function of an air rectifying plate.

[Prior Art] Generally, an air straightening plate on a cab roof is optionally attached later, and its inclination angle is adjusted depending on the load of a truck bed or the height and shape of a trailer.

Conventionally, in this type of air straightening plate, the lower part of the straightening plate is pivotally attached to the front part of the roof, and a stay or hydraulic cylinder rod whose length can be adjusted is installed between the upper inside part of the straightening plate and the rear part of the roof. The tilt angle of the straightening vanes was adjusted by changing the position of the stays fixed by changing the hydraulic pressure or changing the hydraulic pressure (for example, Japanese Utility Model Laid-Open No. 56-150683).

On the other hand, there has been proposed a sun visor which is provided with a sun visor body projecting to the front surface of the windshield so as to be freely displaceable via a support mechanism, and which is provided with an operation knob capable of adjusting the position of the sun visor body from the interior of the vehicle. ). With this operation knob, the sun visor body is located above the windshield to block the sun's rays or located at the front end of the roof so that it can be switched as a deflector.

[Problems to be solved by the invention] However, the former air straightening plate requires a great number of man-hours for mounting on the roof and adjusting the angle of the straightening plate in accordance with the height of the loading platform, etc. There was a problem that the sense of unity with the roof was poor.

Also, in the latter sun visor, the sun visor body is either located above the windshield or at the front end of the roof, and even when there is no need for shading or rectification, it cannot be stowed and protrudes from the vehicle body. Therefore, there is a problem that the air resistance during traveling increases. Further, long holes for making the support mechanism of the sun visor body swingable are formed in the pillars on both sides of the front part of the vehicle body, and these long holes impair the aesthetics of the vehicle and make the vehicle design feel uncomfortable. Furthermore, since the sun visor body that is pivotally attached to the support mechanism does not have a mechanism for adjusting the mounting angle from the inside of the vehicle, when the height of the luggage placed on the roof rack changes, the mounting angle can be manually adjusted outside the vehicle. There was an annoyance that had to be made.

The purpose of the present invention is to make the garnish in the front part of the roof foldable so that the garnish has the function of an air rectifying plate, so that the air flow on the roof during traveling can be achieved without causing any discomfort in the design. (EN) Provided is a cab roof that can be adjusted by a simple operation from the inside of the cab according to the height of a loading platform or the like.

Another object of the present invention is to prevent the garnish from being lowered when not used as an air rectifying plate to increase air resistance during traveling, and not to spoil the aesthetics of the vehicle when the garnish is erected to be used as an air rectifying plate, which is strong. It is to provide a cab roux that is durable against wind pressure.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention will be described with reference to FIG. 1 corresponding to an embodiment.

[Operation] The operation lever 30 is operated from inside the cab to adjust the inclination angle of the garnish 12, and when the inclination angle for improving the air flow on the roof 10 is obtained, the operation lever 30 is locked in the predetermined locking groove 35. To secure the garnish 12 together with the springs 25 and 34.

[Embodiment] Next, an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 to 3, three speed indicators 11 are provided at the front of the cab roof 10 and these indicators 11 are provided.
Covered by garnish 12. The front portion of the cab roof 10 is doubled by a roof panel 13 and a roof rail 14. A drip channel 15 and a recess 16 are formed in the roof panel 13. A lamp housing 17 is attached to the recess 16 by a bracket 18. The housing 17 accommodates the three speed indicators 11 described above. These speed indicator lights 11 are partitioned by a partition plate 19 in the housing 17.

A green and transparent lens 21 is fitted into the opening of the housing 17. The lead wire 22 of the indicator lamp is drawn into the space between the roof panel 13 and the roof rail 14 via a grommet 23 attached to penetrate into the recess 16 and connected to an electric circuit (not shown).

The garnish 12 has a width reaching the left and right ends of the roof 10 and a length reaching the drip channel 15.

The garnish 12 is composed of a transparent portion 12a made of a synthetic resin such as polycarbonate or acrylic that covers the lens 21, and an opaque portion 12b made of a synthetic resin such as dark-colored polypropylene or ABS resin that covers the other portions.
The transparent portion 12a is fitted into the opaque portion 12b.

The front end of the garnish 12 is pivotally attached to the front end of the roof panel 13 via a hinge 24. Garnish 12 on hinge 24
