Description

[Detailed Description of the Invention] The present invention relates to a head guard for industrial vehicles such as forklifts.

Conventional head guards for industrial vehicles can be broadly classified into two types of configurations. That is, one has a structure in which a canopy frame is fixed to the upper ends of the front pillar and the rear pillar, and lattice members are arranged vertically and horizontally with respect to the canopy frame.
One had a flat top plate attached to the canopy frame.

In such conventional head guards, the former allows you to see upwards from the space between the grid members during cargo handling operations, and has good work efficiency. If this is the case, falling objects may pass between the grid members and hit the driver, making it impossible to function as a head guard. Although it has the function of protecting people, it has the disadvantage that upward visibility is poor and work efficiency is significantly reduced.

However, recently, even if sufficient driver protection function cannot be achieved against small falling objects,
The former type of head guard, which uses a grid member, is often used because it provides good upward visibility and is highly efficient.

The purpose of this invention is to provide an improved head guard for industrial vehicles that eliminates the drawbacks of head guards that use grid members and provides sufficient protection for drivers even from small falling objects. The gist is that a flat top plate is removably disposed on the lower surface of the lattice member so that the space between the lattice members can be closed off with respect to a canopy frame on which the lattice members are arranged.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the figures, 1 is a vehicle body frame supported by front and rear wheels 2 and 3, and 4 and 5 are upwardly supported at the front and rear positions of the vehicle body frame 1. A pair of protruding and fixed left and right front pillars and a rear pillar, 6 a canopy frame fixed to the upper ends of the front pillar and rear pillars 4 and 5, 7 a front and rear end of the canopy frame 6 having a substantially rectangular shape; This is a lattice member consisting of a plate member 7A to which is fixed, and a rod member 7B fixed perpendicularly to the plate member 7A, and the lattice member 7 is arranged vertically and horizontally within the enclosing plane of the canopy frame 6. has been done. The above structure is almost the same as that of a conventional head guard. The main structure of this invention is the canopy frame 6.
A flange portion 6A is formed at the inner lower part of the lattice member 7 on three sides, including the front end and left and right ends excluding the rear end, and is substantially parallel to the lattice member 7, and the top plate 9 is removably attached to the flange portion. be.

That is, with the outer peripheral part of the top plate 9 fitted into the inner groove of the rubber frame 10 which has grooves formed on the inner and outer sides, the outer groove of the rubber frame 10 is formed in the canopy frame 6 from the rear end of the canopy frame 6. flange part 6
The top plate 9 is configured to be able to be attached to the flange portion 6A of the canopy frame 6 by inserting it so as to fit into the top plate A.

With the device of the present invention configured in this way, the top plate can be attached as necessary only when working in a place where there are small falling objects, and this has the effect of further improving worker safety. It is.

Furthermore, since the top plate is placed under the lattice member, even if a relatively large object falls, it will be protected by the lattice member and will not directly damage the top plate. There is.

In addition, if a transparent plastic plate or the like is used as the top plate of the present invention, it is possible to secure an upward view even when the top plate is attached, which has the effect of further improving work efficiency.

In addition, the above-mentioned top plate is fitted into the flange formed on the canopy frame so that it can slide horizontally, so although it has a shape that can sufficiently withstand external forces in the vertical direction, it is difficult to attach and remove it. It also has the effect of being extremely easy to perform.
