Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a work light device for a freight vehicle, which is used to illuminate a loading platform during nighttime work.

(Prior Art) When loading and unloading cargo at night or in a dark place, it is convenient to have a work light that illuminates the cargo platform.

Conventionally, work lights have been installed on freight vehicles with the irradiation surface of the lamp 1 directed toward the loading platform and exposed on the cab back panel 2, as shown in FIG.

(Problem that the invention attempts to solve) However, the work light installed in this way,
This method has the following problems.

Since the lamp is installed facing toward the cargo bed side, it may be damaged if it hits the cargo.

Turning on and blinking requires going outside the driver's cabin, which is inconvenient.

If you forget to turn off the lamp and continue driving, it will cause trouble to the vehicles behind you.

If a canopy is not attached to the loading platform, there is a risk of electrical leakage due to rain, etc.

The object of the present invention is to provide a work light device that solves these problems. In addition, the Utility Application (1983) applies to devices devised and filed for the same purpose.
There is issue 012997.

(Means for Solving the Invention) As a means for solving the above problems, the present invention provides a hole in a part of the cab back panel, and attaches a rotating panel to the hole through a hinge and a stopper arm. The present invention is characterized in that a lamp is attached to the rotating panel.

(Function) In such a configuration, when the loading platform is illuminated with a lamp, the rotating panel rotatably attached to the cab back panel by a hinge is rotated toward the loading platform, and the stopper arm is used to rotate the rotating panel. All you have to do is maintain this posture. At this time, since the lamp is attached to the rotating panel, it becomes possible to illuminate the loading platform.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. FIG. 4 shows a truck equipped with the present working light device, and the mounting position is above the back window 3. FIG. 1 is a partially enlarged sectional view taken along the - plane of FIG. 4. A recess 2a is formed in the cab back panel 2, and a hole 2c is provided in the bottom surface 2b of the recess. The upper part of the rotating panel 4 is attached to the cab back panel 2 by a hinge 5 so as to cover the recess 2a. One end of a stopper arm 6 made by a so-called pantograph method is attached below the rotating panel 4, and the other end of the stopper arm 6 is attached to the bottom surface 2b of the recess.

A lamp 7 is placed on the side of the rotating panel 4 facing the driver's cabin.
is attached, and a switch 8 having a plunger 8a is attached to the bottom surface 2b of the recess.
The lamp 7 is as shown in Fig. 3, and the lever 7
It is possible to switch between ON, OFF and AUTO in 3 steps using a. Lamp 7 is AUTO
When set to , when the plunger 8a is activated and the switch 8 is turned on or off, the light is turned on or off, respectively.

A magnet 9 is attached to the rotating panel 4, so that the rotating panel 4 is fixed to the bottom surface 2b of the recess when the stopper arm 6 is folded as shown in FIG. Furthermore, the rotating panel 4
There is a weather strip 10 on the periphery for waterproofing.
is attached around the entire circumference, and a handle 11 is attached to the surface facing the loading platform.

In addition, when the rotating panel 4 is rotated and released as shown in Fig. 1, the extension line of the rotating panel 4 is connected to the rear end of the loading platform and forms an angle θ with the horizontal plane. (See Figure 4).

Next, the handling of this work light device constructed as described above will be explained (assuming that the lamp 7 is set to AUTO).

Under normal conditions, the rotary panel 4 is rotated by the action of the magnet 9, as shown in FIG.
is fixed. At this time, the switch 8 is turned off because the plunger 8a is pushed by the rotating panel 4, so the lamp 8 is not lit.

When loading and unloading cargo, the rotating panel 4 is pushed by hand toward the loading platform to set it in the state shown in FIG. 2. Then, the plunger 8a, which had been pressed by the rotating panel 4, is released, the switch 8 is turned on, and the lamp 7 is turned on.

When loading and unloading work is completed, by pinching the center of the stopper arm 6 and lightly pulling it toward you, the rotating panel 4 returns to its original position as shown in FIG. 2, and the lamp 7 turns off. Even if the driver forgets to turn off the lamp 7 at this time, the light from the lamp 7 still enters the driver's cabin, so the driver usually notices this by the time he or she starts the car. Therefore, this work light device has a structure that is effective in preventing forgetting to turn off the lamp. Furthermore, even if you forget to turn off the lamp 7 while driving, the rotating panel 4 is maintained at a constant release angle θ, as described above, and the light from the lamp 7 will not reach behind the loading platform. Therefore, it does not cause trouble to the vehicles behind.

Incidentally, the above-described rotation operation of the rotation panel can be easily performed not only by the driver in the driver's cab but also by an operator in the loading platform by pulling the handle 11 toward the user.

(Effects of the invention) The invention is constructed as described above,
It has the following effects.

By attaching the lamp to the rotating panel,
The lamp can be used both as a work light on the loading platform and as an interior light in the driver's cabin.

Since the lamp is covered by a rotating panel, it will not be damaged by hitting the luggage.

You can easily switch between the loading platform work light and the driver's cabin interior light from within the driver's cabin.
Moreover, if you set the lamp to AUTO,
A structure can be adopted in which the lamp automatically flashes when these are switched.

Even when the lamp is used as a work light, the light enters the driver's cabin, so it is less likely that the driver will forget to turn off the lamp. Furthermore, even if the driver forgets to turn off the lamp, by setting the release angle of the rotating panel to a constant angle, it is possible to prevent the vehicle behind from being a nuisance.

By attaching a member such as a weather strip to the peripheral edge of the rotating panel, effective waterproofing measures can be taken when used as an indoor light. Therefore, electrical leakage due to rain, etc. can be prevented.
