Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vertically movable headlamp for an industrial vehicle such as a forklift truck. [Prior art] Conventionally, as shown in Figs. 6 and 7. The headlamp 9 of the forklift truck 8 is generally fixedly attached above the front pillar 81.

Therefore, as shown in FIG. 6, when the forklift truck 8 is attempting to handle cargo on the warehouse shelf 70 on which the cargoes 71 to 74 are placed in multiple stages, it is not possible to illuminate from the bottom to the top at once.

That is. Since the headlamp 9 is fixed to the front pillar 8l facing in one direction, for example, when it is possible to illuminate the upper range A-B, it is possible to illuminate the lower range B-C and also the ground plane E. I can't. Furthermore, since the headlamp 9 is mounted above the front pillar 81, even if the illumination angle of the headlamp 9 is changed. The ground surface E may not be sufficiently illuminated.

Also. Japanese Utility Model Application Publication No. 62-52038 proposes a headlamp rotation device that can arbitrarily change the illumination angle. This headlamp rotation device is attached to a bracket 92 fixed to the front pillar 81, as shown in FIG. A headlamp main body 9l is placed in front of it, and an arc-shaped set plate 93 is placed behind it.

Then, attach the shaft 910 attached to the rear of the headlamp body 91. Insert into the rotation hole 930 of the set plate 93. and. Thread the wing nut 94 onto the threaded portion of the shaft 910. Therefore, in the headlamp 9, by moving the shaft 910 up and down. Change the lighting direction of the headlamp 9. After the illumination direction is set at an arbitrary position, the position is fixed with a wing nut 94. [Try to solve III! ! ) However, even with the latter headlamp, the illumination angle can be changed arbitrarily. Like the former headlamp above, it is fixed above the front pillar, so it provides insufficient illumination, especially on the ground. Also. The rotation device is also complicated. Also, for any of the above headlamps. The cord that connects the headlamp to the power source is. Billa -81. It is wired along the head guard 82. As a result, the cord could be accidentally cut during work, or the cord could become an obstacle for workers when getting on and off the machine. That is. There was a problem with the cord storage. The present invention was made in view of these conventional problems, and allows the vertical position of the headlamp to be changed arbitrarily in industrial vehicles such as forklift trunks. The aim is to provide a headlamp with excellent cord storage. [Means for solving the problem] The present invention. This headlamp is attached to a hollow front pillar of an industrial vehicle such as a forklift truck, and the headlamp is attached to the front pillar so that it can move up and down, while a cord connected to a power source can be extended and retracted inside the front pillar. Store it in. In the headlamp of an industrial vehicle, the front pillar is provided with a cord guide hole in the vertical direction, and the cord is connected to the headlamp through the cord guide hole. In the present invention, the headlamp is. Attaches to the front pillar so that it can move up and down. As shown in the example, such an installation method involves moving the slide plate to which the headlamp is attached up and down using the cord guide hole. Alternatively, a sliding frame with a headlamp attached may be moved around the front pillar and moved up and down. The front pillar is a pillar that supports the ceiling of the head guard in the forklift 1/truck, and has various shapes such as a hollow square pillar, a polygonal pillar, and a cylindrical pillar. In addition, the above cord guide hole is attached to the above front pillar.
The cord is installed in the vertical direction, and the tip of the cord stored in the hollow part of the front pillar is large enough to follow the vertical movement of the headlamp. In addition, the above-mentioned cord is made by covering a mild steel wire with an insulating coating material such as rubber, such as a curl wire. It is preferable to use foldable and expandable wire. Then, the cord is stored in the biller, and one end of the cord is inserted through the cord guide hole. 7 Connect electrically to the dramp. [Function] In the present invention, when moving the headlamp up and down, first a fixture is used to fix the headlamp in a predetermined position. For example, loosen the wing nut.

and. 1. Move the soda lamp along the front pillar to the specified position.

Next, fix the headlamp to the pillar using the fixing device mentioned above. On the other hand, the above cord is extendably connected to the above head simp within the pillar. Therefore. When the headlamp moves upward or downward, the tip of the cord moves up and down following the movement of the headlamp through the cord guide hole. [Effect] As above. According to the headlamp of the present invention, the position of the headlamp can be moved up and down depending on the position of the object to be illuminated.

Also. The cord is always stored in the pillar in an expandable and retractable state, so the cord does not get in the way during work or when the driver gets on and off the vehicle.

therefore. According to the present invention, the vertical position of the headlamp can be changed arbitrarily. It is also possible to provide a headlamp with excellent cord storage.
