Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a head guard cover mounted on a head guard of an industrial vehicle such as a forklift.

[0002]

2. Description of the Related Art In an industrial vehicle such as a forklift, a head guard for protecting a driver is provided, and a head guard cover for avoiding rain is mounted on the upper surface of the head guard. However, if only the flat ceiling of the head guard is covered with a seat, rainwater is likely to collect on the seat, and when the vehicle starts or stops, the water collects from the seat all at once and wets the driver.

For this reason, rain gutters are provided in front of and behind the head guard, and a bar material such as urethane foam is attached to the central portion of the head guard cover to form downward inclined surfaces in the front, rear, left, and right directions in the cover, and the head guard's It is known that pipes and ropes are attached to both sides intersecting with the gutter to form a flange for guiding rainwater to the gutter to prevent water from accumulating in the seat (Acts 6)
2-12688).

Further, the head guard cover is entirely or partially formed in the air chamber with a thin and transparent flexible material, and the bulge of the air chamber has an inclination to allow rain water to flow down in a predetermined direction, or the rain water can flow down. There is also an example in which a damming fence is formed (Japanese Utility Model Laid-Open No. 58-85520).

[0005]

However, in the former case, the number of members to be assembled to the seat is increased, which is disadvantageous in terms of cost, and the head guard is fixed with a string while the cover is unfolded. There was a problem that it took time and effort. On the other hand, in the latter case, when the air chamber is inflated, the cover spreads out in a certain shape, so it suffices to mount the cover on the head guard and fix it. It was difficult to give a sufficient angle, and there was a problem that the water accumulation in the sheet could not be eliminated sufficiently.

The present invention aims to solve such problems.

[0007]

According to a first aspect of the present invention, in a head guard cover mounted on the upper surface of a head guard of an industrial vehicle, a soft material such as vinyl is pressure-bonded to the central portion of the head guard parallel to the rain gutter. To the side of the head guard that is connected to the rain gutter, and ridge-shaped air chambers are provided on both sides, and the crimping part of the flexible material excluding these areas forms a downward slope to the head gutter.

In the second invention, the core wire for preventing the slack is put on the inclined surface in the first invention.

In the third invention, the core wire of the inclined surface in the second invention is arranged at a position overlapping the crosspiece of the head guard.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the cover portion that covers the rear half of the head guard is formed of colored vinyl.

[0011]

According to the first aspect of the present invention, since the swelling of the air chamber forms the descending inclined surface of the head guard toward the rain gutter, the rainwater travels along the inclined surface divided into the front and rear with the central air chamber as a boundary. It flows to the rain gutter of the guard. Further, the air chambers on both sides of the head guard that intersect with the rain gutter regulate the downward flow of the rain water to the side, and promote the flow to the rain gutter, so that it is possible to prevent water accumulation on the seat. Therefore, a large amount of accumulated water does not fall at a dash when the vehicle starts, stops, or turns. In this case, the head guard cover spreads in a certain shape when the air chamber is inflated, and is lightweight and easy to handle. Further, since the region excluding the air chamber is formed by pressure bonding, the slack of the inclined surface is small in spite of using a flexible material such as vinyl.

According to the second invention, since the slack of the inclined surface can be suppressed by the core wire, it is possible to effectively prevent the accumulation of water in the sheet.

According to the third aspect of the invention, the core wire is hidden by the vertical crosspiece of the head guard, so that the driver's upward view is not hindered.

According to the fourth aspect of the invention, it is possible to obtain the effect of blocking the sunlight in the rear half of the head guard cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a head guard 1 of a forklift truck, in which columns 2 are erected on the front, rear, left and right sides of a vehicle body, and front and rear columns 2 support vertical beams 4 on a ceiling 3, respectively. The ceiling 3 is formed by connecting the central portions of the vertical beams 4 with the cross rails 5, and arranging the rain gutters 6 each having a groove-shaped cross section that opens upward at each of a front end portion and a rear end portion between the vertical beams 4, A vertical rail 7 is assembled between each rain gutter 6 and the horizontal rail 5.

Both ends of the rain gutter 6 are closed by vertical beams 4,
Rainwater is discharged to the road surface through a tube (not shown). Reference numeral 8 is a cover locking hook of the head guard 1, which is arranged on the inner edge of the rain gutter 6.

The head guard cover used for such a head guard 1 is formed by pressure-bonding vinyl as shown in FIG. 2 so that both sides of the head guard 1 intersect with the rain gutter 6 from the central portion parallel to the rain gutter 6. A ridge-shaped air chamber 11 is provided to the portion, and a vinyl pressure bonding portion 12 excluding these regions forms a downward slope 12a to the rain gutter 6 of the head guard 1.

In order to prevent the slack from being formed on the inclined surface 12a of the cover 10, the core wire 13 is inserted between vinyls in parallel with the inclination direction to form a crimp. The core wire 13 is arranged at a position overlapping the vertical rail 7 of the head guard 1 so as not to hinder the driver's upward vision. Locking holes 14 corresponding to the hooks 8 of the head guard 1 are formed at the front and rear edge portions of the cover 10, and reinforcing core wires 15 are also inserted into these edge portions at the time of pressure forming. Reference numeral 16 is an air inlet of the air chamber, which is provided with a valve for sealing it.

The head guard cover 10 is attached to the head guard 1 by hooking the locking holes 14 on the hooks 8, and as shown in FIG. 3, the swelling of the air chamber 11 causes the descending inclined surface 12a of the head guard 1 to the rain gutter 6 to fall. In order to form (provided by the inclination angle θ), the rainwater flows to the rain gutter 6 of the head guard 1 along the inclined surface 12a divided into the front and rear with the air chamber 11a at the center as a boundary. Further, the air chambers 11b on both sides intersecting with the rain gutter 6 of the head guard 1 restrict the falling of the rain water to the side, and the flow thereof is urged to the rain gutter of the head guard, so that a water pool occurs in the seat. Can be prevented.

As a result, it is possible to solve the problem that a large amount of accumulated water runs off at a dash when the vehicle starts, stops, or turns, and wets the driver. Head guard cover 1
0 is also lightweight in terms of material, and expands to a certain shape when the air chamber 11 is inflated, and can be freely deformed when air is removed, so that it can be easily attached to the head guard 1 and handled.

Further, since the area excluding the air chamber 11 is formed by pressure bonding, the inclined surface 1 can be formed by using a soft material such as vinyl.
The slack of 2a is small, and since the core wire 13 holds the inclined surface uniformly, it is possible to effectively prevent the accumulation of water on the sheet. The head guard cover 10 is made of transparent vinyl, but if the rear half of the head guard cover 10 is made of colored vinyl, the effect of blocking sunlight is obtained.

As another embodiment, in order to suppress the slack of the inclined surface, a region 11c may be added to the air chamber 11 to push the central portion of the inclined surface 12a forward and backward as shown in FIG. Further, the rear half of the head guard cover 10 is not required to have an upward view so much, and therefore, as shown in FIG. 5, a plurality of regions 11c may be added to the air chamber 11 to push the inclined surface 12a in parallel in the front-rear direction. .

[0023]

According to the first invention, in the head guard cover mounted on the upper surface of the head guard of the industrial vehicle,
By forming a flexible material such as vinyl by crimping, an air chamber that is connected like a ridge is provided from the central part parallel to the rain gutter of the head guard to both sides intersecting the rain gutter of the head guard, and the flexible material excluding these areas is Since the head guard rain gutter slope was formed at the crimping part, rainwater is controlled to flow to the side while flowing smoothly to the head guard rain gutter along the slope surface, so there is a pool of water on the seat. It can be effectively prevented from occurring. In addition, the material is also lightweight, and it expands to a certain shape when the air chamber is inflated, and it can be freely deformed by letting out the air, so it can be easily attached to the head guard and the air chamber is excluded. Since the region is pressure-bonded, it is possible to obtain the effect that the slack of the inclined surface is small in spite of using a flexible material such as vinyl.

According to the second aspect of the present invention, since the core wire for preventing the slack is inserted in the inclined surface, the inclined surface can be held, and the accumulation of water on the sheet can be effectively prevented.

According to the third aspect of the invention, since the core wire of the inclined surface is arranged at a position overlapping the crosspiece of the head guard, it cannot be seen from the driver's seat and does not obstruct the upper field of view.

According to the fourth aspect of the present invention, since the cover portion covering the rear half of the head guard is made of colored vinyl, it is possible to obtain the effect of blocking the sunlight on the driver's seat.
