Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lamp support device, and relates to supporting the lamp of a side marker light installed in a plow such as a snow removal dozer, a two-way dozer, or a wheel loader.

[Conventional technology]

Conventionally, vehicle width lights have been attached to the tops of both ends of plows such as snow removal dozers, and the vehicle width lights have lamps fixed to the tops of both ends of the plow, and these lamps are surrounded by lamp guards that open on the front and rear sides. , which was supposed to protect the lamp.

[Problem that the invention attempts to solve]

In conventional vehicle side lights as described above, when snow, etc., climbs over the top of the plow during snow removal work, the snow, etc. enters the inside of the lamp guard from the front, presses the lamp, and damages the lamp and lamp support. I had a problem causing damage.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a lamp support device that can prevent damage to the lamp.

[Means for solving problems]

The present invention is a lighting device for a construction machinery vehicle, in which one fixed piece 12 of a hinge 11 is fixed to the inside of a lamp guard 7 whose front and rear sides are open, and the other movable piece 1 of the hinge 11 is rotatable.
A lamp 6 is attached to the hinge 11, and an elastic body 16 is attached to the hinge 11 to bias the movable piece 13 in a direction to close the fixed piece 12 of the hinge 11 and to place the lamp 6 inside the lamp guard 7. This is a lamp support device.

[Effect]

In this invention, when the lamp is pressed from the front, it rotates to the rear of the lamp guard via the hinge and retreats, and when the pressure is removed, the lamp is rotated to a predetermined position inside the lamp guard by the elastic body attached to the hinge. It will be restored.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 4 shows a wheel type loader as a construction equipment vehicle, which is attached to the tip of a lift arm 1 that is moved up and down by a lift cylinder (not shown), and is used to move left and right like a slide-angling plow. A plow 2 whose left and right ends are angle-adjustable in the front-rear direction is installed, and side-marker lights 5 as lighting equipment are provided at the upper portions of both ends of the plow 2.

As shown in FIGS. 1 to 3, the side marker light 5 has a lamp 6, and this lamp 6 is installed inside a lamp guard 7, which is fixed to the top of both ends of the plow 2 and has an open front and rear surface. Mounted by a support member 8, the lamp 6 is enclosed within a lamp guard 7.

The lamp 6 includes a lamp body, a light source disposed within the lamp body, and a reflecting mirror disposed opposite to the light source, and a lens is provided on the front surface of the lamp body.

This support member 8 has a hinge 11, which includes one fixed piece 12 and the other movable piece 13.
A hinge shaft 15 is inserted through the cylindrical connecting portions 14, 14, and the fixed piece 12 and the movable piece 13 are connected to each other so as to be rotatable in opening and closing about the connecting portion 14. The upper end of the hinge shaft 15 protrudes from the connecting portion 14, and a spring 16 as an elastic body is fitted onto the hinge shaft 15.
Both ends 17, 17 of the fixed piece 12 and the movable piece 13 are hooked to the outer upper ends of the fixed piece 12 and the movable piece 13, and the fixed piece 1
2 and the movable piece 13 in the direction of closing. Further, the fixing piece 12 has a plurality of fixing holes 18.
is provided, and one end of a lamp stay 21 formed in a substantially L-shape is fixed to the outer side of the movable piece 13. A support hole 22 is formed in the center of the other end of the lamp stay 21, into which a lamp support part 26 protruding from the lower part of the lamp 6 and having a threaded part 25 on the outer periphery is inserted from above. A nut 28 is screwed onto the lamp support portion 26 protruding from the lower surface of the lamp stay 21 via a washer 27 to connect and fix the lamp 6 to the lamp stay 21.

Then, the fixing piece 12 of the hinge 11 is joined to the inside of one side plate 7a of the lamp guard 7, and the fixing hole 18 is inserted through the fixing hole 18 of the fixing piece 12.
A bolt 31 is inserted into a mounting hole 30 provided in the side plate 7a, and a nut 33 is screwed onto the tip of the bolt 31 via a washer 32 to fix the hinge 11 to the lamp guard 7.

When the plow 2 equipped with the vehicle width lights 5 configured in this way is used to remove snow, for example, and snow, etc., climbs over the upper end of the plow 2, the snow, etc. will be pushed into the lamp guard 7 from the front. When the lamp 6 is pressed against the lamp 6, the lamp 6 rotates backward through the lamp stay 21 and the hinge 11 and against the spring 16, and retreats against the pressing force of snow or the like. Further, when the pressure from snow or the like is removed, the lamp 6 is rotated back to a predetermined position within the lamp guard 7 due to the elasticity of the spring 16.

Furthermore, since the support member 8 that supports the lamp 6 has a compact structure consisting of only the hinge 11 and the lamp stay 21, it can be installed later on the general standard lamp guard 7 of the already delivered vehicle. 8
The front visibility is not obstructed by the installation of the .

Further, in the above embodiment, the fixing piece 12 of the hinge 11
Although the hinge 11 and the lamp guard 7 are fixed to each other by bolts 31 and nuts 33, the fixing piece 12 of the hinge 11 may be fixed to the lamp guard 7 by welding.

[Effect of idea]

According to the present invention, the lamp is provided on the lamp guard so that it can be rotated and retracted rearward via the hinge, so that when the lamp is pressed from the front, it is rotated and retracted rearward of the lamp guard via the hinge. When the pressure is removed, the lamp is rotated back to the specified position inside the lamp guard by the elastic body attached to the hinge.
The lamp can be reliably protected, and by fixing the hinge to the general standard lamp guard of the existing vehicle from the rear, the lamp can be supported in a rotatable manner, and the forward visibility can be improved by installing the hinge etc. It does not cause any trouble.
