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 preventing rain is mounted on an upper surface thereof. However, if the flat ceiling of the head guard is merely covered with the seat, rainwater tends to accumulate on the seat, and when the vehicle starts or stops, the accumulated water flows from the seat at once and wets the driver.

[0003] Therefore, rain gutters are provided before and after the head guard, a rod material such as urethane foam is attached to the center of the head guard cover, and a downwardly inclined surface is formed on the cover in four directions of front, rear, left and right. It is known that pipes and ropes are attached to both sides intersecting the rain gutter to form a flange that guides rainwater to the rain gutter, thereby preventing a water pool from being generated in the sheet (Jun.
2-1688 publication).

Further, all or a part of the head guard cover is formed in the air chamber with a thin and transparent flexible material, and the swelling of the air chamber causes the cover surface to have a slope for flowing rainwater in a predetermined direction, or to prevent rainwater from flowing down. There is also an example in which an enclosure for damming is formed (Japanese Utility Model Laid-Open No. 58-85520).

[0005]

However, in the former case, the number of members to be attached to the seat increases, which is disadvantageous in terms of cost, and the head guard is fixed to the head guard with the string while expanding the cover. There was a problem that time was required. In that case, in the latter case, when the air chamber is inflated, the cover spreads in a certain shape, so it is only necessary to fix it by placing it on the head guard. There is a problem that it is difficult to provide a sufficient angle, and the water pool of the sheet cannot be sufficiently eliminated.

An object of the present invention is to solve such a problem.

[0007]

According to a first aspect of the present invention, in a head guard cover mounted on an upper surface of a head guard of an industrial vehicle, a flexible material such as vinyl is crimped to form a central portion parallel to the rain gutter of the head guard. A ridge-shaped air chamber is provided on both sides intersecting the rain gutter of the head guard from above, and a downward slope to the rain gutter of the head guard is formed by a crimping portion of the flexible material excluding these regions.

In the second invention, a slack preventing core wire is inserted into the inclined surface in the first invention.

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

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

[0011]

According to the first aspect of the present invention, the swelling of the air chamber forms a downward slope to the rain gutter of the head guard, so that the rainwater travels along the inclined plane that is divided back and forth with the central air chamber as a boundary. It flows into the guard gutter. In addition, since the air chambers on both sides of the head guard intersecting with the rain gutter regulate the flow of rain water to the side and urge the flow to the rain gutter, it is possible to prevent the accumulation of water in the seat. Therefore, a large amount of accumulated water does not flow down at once when the vehicle starts, stops, or turns. In this case, when the air chamber is inflated, the head guard cover spreads in a certain shape, and is lightweight and easy to handle. In addition, since the area excluding the air chamber is formed by pressure bonding, slackness of the inclined surface is less than that of using a soft material such as vinyl.

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

According to the third aspect of the present invention, the core wire is hidden by the vertical rail of the head guard, so that the driver does not obstruct the upper view.

According to the fourth aspect of the invention, the effect of blocking the solar radiation from the rear half of the head guard cover can be obtained.

[0015]

FIG. 1 shows a head guard 1 of a forklift, in which columns 2 are erected on the front, rear, left and right sides of a vehicle body, and the front and rear columns 2 support vertical beams 4 of a ceiling 3 respectively. The ceiling 3 connects a central part between the vertical beams 4 with a horizontal bar 5, and has a rain gutter 6 having a groove-shaped cross section that opens upward at each of a front end and a rear end between the vertical beams 4. A vertical bar 7 is assembled between each rain gutter 6 and the horizontal bar 5.

The rain gutter 6 is closed at both ends by the longitudinal beams 4,
Rainwater is discharged to the road surface through a tube (not shown). Reference numeral 8 denotes a hook for locking the cover of the head guard 1, and is provided on the inner edge of the rain gutter 6.

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

In order to prevent the slanted surface 12a of the cover 10 from being loosened, a core wire 13 is inserted between vinyls in a direction parallel to the slant direction, and is formed by pressure bonding. The core wire 13 is arranged at a position overlapping the vertical rail 7 of the head guard 1 so as not to obstruct the driver's upward view. Engagement holes 14 corresponding to the hooks 8 of the head guard 1 are formed at the front end side and rear end side edges of the cover 10, and a reinforcing core wire 15 is also inserted into these edges at the time of crimping. Reference numeral 16 denotes an air inlet of an air chamber, which is provided with a valve for sealing the air inlet.

Then, the head guard cover 10 is attached to the head guard 1 by hooking the locking hole 14 to the hook 8, and the swelling of the air chamber 11 causes the downward slope 12a of the head guard 1 to the rain gutter 6 as shown in FIG. (Given by the inclination angle θ), the rainwater flows to the rain gutter 6 of the head guard 1 along the inclined surface 12a that is divided into front and rear portions with the center air chamber 11a as a boundary. In addition, since the air chambers 11b on both sides of the head guard 1 intersecting the rain gutter 6 restrict the rain water from dropping to the side, the flow of the rain water is urged toward the rain gutter of the head guard. Can be prevented.

As a result, even when the vehicle starts, stops, or turns, a large amount of accumulated water flows down at once, and the problem that the driver gets wet can be solved. Head guard cover 1
Numeral 0 is both light in material and lightweight, expands into a certain shape when the air chamber 11 is inflated, and is free to deform when the air is released, so that handling such as mounting to the head guard 1 becomes easy.

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

As another embodiment, in order to suppress the slack of the inclined surface, a region 11c which protrudes the central portion of the inclined surface 12a in the front-rear direction may be added to the air chamber 11 as shown in FIG. Furthermore, since the rear half of the head guard cover 10 does not require much upward view, a plurality of regions 11c that project in parallel with the inclined surface 12a in the front-rear direction may be added to the air chamber 11 as shown in FIG. .

[0023]

According to the first invention, in a head guard cover mounted on an upper surface of a head guard of an industrial vehicle,
By forming a flexible material such as vinyl by crimping, a ridge-shaped air chamber 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 provided. Since the crimping section forms a slope that descends to the rain gutter of the head guard, rainwater is restricted from flowing down to the side and flows smoothly down the slope to the rain gutter of the head guard. This can be effectively prevented. In addition, it is lightweight in material, it expands to a certain shape when the air chamber is inflated, and it is free to deform when bleeding, so it is easy to handle such as mounting to the head guard, and excluding the air chamber Since the region is formed by pressure bonding, there is obtained an effect that the slack of the inclined surface is less than the use of a flexible material such as vinyl.

According to the second aspect of the present invention, since the slack-preventing core wire is inserted into the inclined surface, the inclined surface can be held, and water can be effectively prevented from being formed on the sheet.

According to the third aspect of the present invention, since the core wire of the inclined surface is disposed at a position overlapping the crosspiece of the head guard, it is not seen from the driver's seat and does not hinder the upward view.

According to the fourth aspect of the present invention, since the cover for covering the rear half of the head guard is formed of colored vinyl, an effect of blocking sunlight from entering the driver's seat can be obtained.
