Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is particularly suitable for refrigeration and forklift trucks.
The present invention relates to a dew condensation preventing structure for a head guard of a forklift truck used inside and outside a refrigerator.

(Prior Art) When a forklift truck frequently moves in and out of a refrigerating / refrigerating warehouse, the temperature difference between the outside temperature and the temperature of the forklift truck's vehicle body becomes extremely large when the vehicle goes out of the warehouse. Condensation occurs, especially on the head guard as water droplets that fall on the driver and permeate the driver's head and clothes, causing discomfort, and causing a decrease in alertness, resulting in a work environment. There was a problem of significantly inhibiting

Conventionally, in order to solve this kind of problem, the head guard itself is used as a gutter to let water droplets due to dew condensation flow outside the vehicle body of the forklift truck, or a flat plate such as acrylic resin is diagonally attached to the entire lower surface of the head guard. Water droplets due to dew condensation on the head guard were flowing out of the body of the forklift truck.

(Problems to be solved by the invention) In the conventional technology, in the former case, dew condensation occurs on the gutter itself, so that there is a problem that the dew condensation formed on the lower surface of the gutter also falls on the driver as water droplets. However, since the flat plate is attached to the whole area of the lower surface of the head guard in the latter, even if a transparent flat plate is used for the flat plate, fog due to dew condensation occurs and the upper field of view is impaired, which is dangerous in performing cargo handling work. was there.

(Means for Solving the Problems) In view of the above problems, the present invention is, in the first invention, a head guard of a forklift truck, wherein a frame member and a vertical member of the head guard are formed of resin or rubber. A structure in which a frame body having a substantially U-shaped cross section is engaged from below, a groove body formed of a monoplastic resin is fixed to the lower surface of the frame body, and a discharge pipe protruding downward from the groove body is provided. In the second invention, the above-mentioned problem is solved by making the head guard inclined.

(Operation) To explain the operation of the present invention, the dew formed on each component of the head guard becomes a water drop, and as shown by the arrow in FIG. 2, along the frame, between the arm bending portion and the mounting portion of the groove body. Flows into the groove. Further, although a slight amount of dew condensation occurs on the frame body, the water droplets caused by this also flow into the groove portion between the arm bending portion and the mounting portion of the groove body, as in the above-described action.

Since the groove body is made of a monoplastic resin, it has a very low thermal conductivity and is hardly affected by an external temperature change, so that no condensation occurs. Furthermore, since air bubbles exist solely inside the resin, it does not permeate water, so that the water droplets that flow down to the groove are guided along the slope and discharged to the outside of the forklift truck body through the discharge pipe. You can

(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 8, reference numeral 1 is a well-known forklift truck that can perform cargo handling / traveling operation, and a head guard 2 for protecting a driver from a fall of a load from a high place and the like is provided via left and right columns 3a and 3b. And is fixed to the vehicle body 1.

The head guard 2 can be tilted. For example, FIG. 3 shows the structure of the head guard 2 tilted forward by θ ₁ from the horizontal plane, and FIG. 4 shows the structure of the head guard 2 tilted backward by θ ₂ from the horizontal plane.
Further, although not shown, it can also be tilted in the left-right direction.

As shown in FIG. 7, the head guard 2 forms an outer frame with frame members 2b and 2c, and vertical members 2a are fixed in the outer frame at substantially equal intervals.

In FIGS. 1 and 2, reference numeral 4 denotes a frame body made of resin or rubber and having a substantially U-shaped cross section.
Protrusions 4c and 4c are provided on the surfaces of b and 4b facing each other.

Since the frame body 4 has a cored bar 5 therein,
The shape of the head guard 2 is appropriately deformed (FIG. 1 shows the shape before the deformation and FIG. 2 shows the shape after the deformation), and the projections 4c, 4c are locked to the frame members 2b, 2c and the vertical member 2a of the head guard 2. Can be engaged.

Reference numeral 7 denotes a groove body formed of a single-ply resin, and a mounting portion 7a protruding from the center is fixed to the lower surface of the horizontal portion 4a of the frame body 5.

Since the single-cell resin has bubbles alone, unlike the continuous resin (so-called sponge), it has the property of not permeating water. Further, the groove body 7 is provided with arm curved portions 7b, 7b extending upward and to the left and right of the mounting portion, and the mounting portion 7a and the arm curved portion 7b form a groove portion 7c.
It also prevents water droplets from falling due to dew condensation.

Reference numeral 8 denotes a discharge pipe, which is provided in the groove portion 7c of the groove body 7 and discharges the water droplets flowing down to the groove portion 7c to the outside of the forklift truck 1 body.

When the head guard 2 is tilted, the drain pipe 8 can be formed in the gutter 9 that collects the water drops that have flowed down into the groove portion 7c, and the drain pipe 8 can flow out of the vehicle body of the forklift truck 1.

Further, the shape of the groove body 7 is not limited to this embodiment, and it is possible to form the groove body 7 so as to cover the frame body 5 as shown in FIG.

(Effect of the Invention) Since the present invention employs the above-mentioned configuration, even if dew condensation occurs on the head guard, the water droplets due to the dew condensation do not reach the driver and can be reliably discharged to the outside of the vehicle body.
Therefore, the working environment of the driver can be improved and workability can be improved.

In addition, since it is easy to attach and detach the frame, repair,
There is an effect that exchange can be performed easily.
