Definitions
- the present invention relates to a head guard structure for a forklift.
- a head guard is mounted to a forklift used to carry, load and unload various loads.
- a head guard is a guard unit for protecting a driver from a fallen load when a load falls due to collapse of loads upon loading or unloading loads at a height.
- the head guard includes a pair of right and left front pillars disposed at the front of a vehicle of a forklift at intervals in the vehicle width direction, a right and left rear pillars disposed at the rear of the vehicle at intervals in the vehicle width direction, and a ceiling disposed over the front pillars and the rear pillars.
- the head guard has high rigidity to protect the driver from fallen loads.
- Patent Document 1 discloses a head guard structure.
- a front cover is fixed by bolts to right and left pillars at the front of a head guard provided for a vehicle body.
- This front cover is formed from transparent resin having strength and durability, such as polycarbonate.
- a ceiling cover having the same configuration is provided to prevent a driver from getting wet when it rains.
- Patent Document 2 discloses a cutout disposed on a roof cover of a head guard to load and unload a battery of a forklift.
- the cutout has a U shape including an opening at a side of a center portion in the vehicle front-rear direction.
- a roof board of the roof cover is formed from a metal plate such as an iron plate, a rigid resin plate including FRP, or the like.
- Document JP S58 221775 describes a overhead guard for a forklift, wherein the front half overhead section is made of crosspieces. Consequently when lifting a mast to perform loading work at high position, the leading edge of fork and load can be confirmed through the gap between the crosspieces to cause no trouble for the work, while the falling material is blocked by a cover plate to protect the driver.
- Document JP S58 221776 describes a head guard structure for a forklift for protecting a driver's head from hurting without sacrifice of the overhead view, by making round the lower end of a strength member of an overhead guard roof.
- a plurality of rectangular rods are extending in the front and back directions of car and arranged with proper interval in the lateral direction between a front member and V-shaped member.
- Patent Document 1 the front and the ceiling are covered by polycarbonate or the like.
- Polycarbonate produces slight scars on its surface due to aging, which reflect light diffusely and considerably detract the visibility.
- Patent Document 2 discloses a cutout for loading and unloading batteries of the vehicle disposed on a roof cover of a head guard. The cutout is closed by a lid.
- the structure becomes complex, and the cost rises due to the increased cost and production workload for the reinforcement members.
- the roof board of the roof cover is formed from a metal plate such as an iron plate and FRP, the roof board is opaque, and the upward view may not be ensured.
- An object is to provide a head guard structure for a forklift that prevents a driver from getting wet directly from rain, whereby it is possible to directly check tips of forks when the forks carrying a load reach the top position.
- the present invention according to the independent claim 1 is provided.
- the strength and rigidity of the ceiling is high, and it is possible to protect the driver from rainwater when it rains. Also, it is possible to maintain the front upward view during operation of the forklift.
- a position of the front flange surface in the vehicle front-rear direction is disposed at least behind a line connecting tips of forks for placing loads and an eye point of a driver through the intervals between the bar members when the tips of the forks reach a top position and the driver is seated at a rightly seated position.
- a rear edge of the top board may include a rear flange surface bended downward, the rear flange surface including opposite ends in the vehicle width direction respectively fixed to the pair of right and left rear pillars.
- the rear flange surface has a similar effect (an effect to improve rigidity in the vehicle width direction) to that of the front lateral frame, it is possible to reduce the cost.
- the top board may include a plurality of elongated grooves formed to have heights varied in a vertical direction over an entire region of the top board in the vehicle width direction.
- the top board includes a reinforcement member extending in the vehicle width direction, disposed on a side of the top board which is adjacent to a driver's seat and at a position facing the driver's seat.
- the reinforcement member is just disposed on the side of the top board adjacent to the driver's seat, which makes it possible to easily improve the rigidity against fallen objects from above the top board.
- the bar members may each have a rectangular cross section in an orthogonal direction to an axis of each bar member, each bar member being disposed so that long sides of the cross section extend in the vertical direction.
- the intervals between the bar members are large as compared to a case in which the long sides of the rectangular cross sections are disposed in the horizontal direction.
- the upward view is enlarged.
- the rigidity in the vertical direction improves and thus the safety improves.
- a head guard structure whereby it is possible to directly check the tips of the forks on which a load is placed, and to prevent the driver from directly rained on when it rains.
