Abstract

PURPOSE:To ease impact on goods and to obtain a favorable view. CONSTITUTION:A head guard 14 is fixed rearward on a guard provided at an upper end of a mast 10 of a forklift 1. A support 16 is fixed to the head guard 14 over the mast 10 so that the head guard 14 is tilted integrally with the mast 10. When the mast 10 is tilted rearward, a force acts so that a goods having dropped on the head guard 14 slides on the head guard 14 toward the rear, and an impact received by the head guard 14 can be eased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift,
Specifically, it relates to a head guard provided at the upper part of the driver's seat of a forklift.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, the upper end of a mast 53 for raising and lowering a fork 52 is tiltably supported at the front of a forklift 51. Pillars 55a and 55b are provided on both front and rear sides of the driver's seat 54 of the forklift 51, and support head guards 56 provided on the upper part of the driver's seat 54. The head guard 56 protects a worker sitting in the driver's seat 54 and working against falling objects.

In the battery type, a recess 57 is formed in the head guard 56 in the vehicle width direction of the forklift 51. The concave portion 57 allows the hoist to pass through when the battery (not shown) mounted on the forklift 51 is unloaded.

[0004]

However, when a worker sitting in the driver's seat 54 and working to check the rear, he or she does not just check the position directly behind, but rather checks the direction directly behind the pillar 55b. It will be. Therefore, there is a problem that the pillar 55b is obstructive and the rearward confirmation cannot be performed accurately.

Further, when the mast 53 is tilted rearward while the fork 52 carrying a load is at a high position, the load on the fork 52 may collapse and fall onto the head guard 56. Therefore, the head guard 56 must be strong enough to withstand the impact of falling loads.

Further, in the battery type forklift, it is necessary to form a recess 57 for passing the hoist, and a special head guard 56 must be prepared,
There is a problem that its manufacturing is troublesome.

It is an object of the present invention to provide a forklift which can surely confirm the rear side, facilitates the design of the head guard, and can mount a common head guard even if the vehicle type is different.

[0008]

In order to solve the above problems, the present invention provides a forklift in which a mast for raising and lowering a fork can be tilted, and the fork can be tilted by tilting the mast. The main point is that a head guard is provided above the driver's seat.

[0009]

The function of the present invention is that the mast of the forklift is provided with the head guard disposed above the driver's seat, so that the pillar supporting the head guard is eliminated and the rear view is improved. When the mast is tilted forward, the head guard is also tilted forward, which increases the space between the head guard and the driver's seat. or,
When the mast is tilted backwards, the head guard also tilts backwards,
In this state, the obstacle that falls on the head guard slides backward.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a battery type forklift will be described below with reference to FIGS.

As shown in FIG. 1, a forklift 1 is provided with drive wheels 2 and steered wheels 3 at the front and rear. A driver's seat 4 is provided above the forklift 1, and a seat 5 for an operator to sit on is provided. In front of the driver's seat 4, a panel 6 is provided for performing a cargo handling operation of the forklift 1.

A steering wheel 7 is provided on the panel 6,
By operating the steering wheel 7, the steering angle of the steered wheels 3 can be changed. A lift lever 8 and a tilt lever 9 for performing a cargo handling operation are provided on the right side of the steering wheel 7.
Etc. are provided.

A mast 10 is provided at the front of the forklift 1. A fork 11 is supported on the mast 10 so as to be able to move up and down, and a load loaded on the fork 11 is moved up and down by a lift cylinder (not shown).
Tilt cylinders 12 provided on the main body of the forklift 1 are attached to the left and right of the mast 10. The tilt cylinder 12 operates by operating the tilt lever 9, and based on this operation, the upper end of the mast 10 tilts back and forth.

A guard 13 is fixed to the upper end of the mast 10. The guard 13 is provided with a head guard 14 that covers the upper side of the driver's seat 4. Further, a reinforcing support 16 is obliquely provided between the head guard 14 and the mast 10.

Further, when the tilt lever 9 is operated while the fork 11 is slightly elevated and the upper end of the mast 10 is tilted to the front side by the tilt cylinder 12, the head guard 14 is also indicated by a chain double-dashed line in FIG. Tilt forward as shown. Therefore, the space between the seat 5 of the driver's seat 4 and the head guard 14 can be increased. At this time, the hoist for loading and unloading the battery is the head guard 14
It does not interfere with.

When the tilt lever 9 is operated and the mast 10 is tilted rearward by the tilt cylinder 12, the head guard 14 is also tilted rearward as shown by the chain double-dashed line in FIG. Therefore, for example, when the load carried by the fork 11 collapses toward the driver's seat, the head guard 14
Receives the load. At this time, since the head guard 14 is tilted to the rear side, the load slides down to the rear side of the forklift 1.

Next, the operation of the forklift thus constructed will be described. When moving a load on the forklift 1, a worker loads the load on the fork 11. Then, the operator operates the tilt lever 9 to slightly tilt the mast 10 rearward. Further, the operator operates the lift lever 8 to raise the fork 11. Then, the worker runs the forklift 1 to move the luggage to an arbitrary place.

When a load loaded on the fork 11 collapses, the mast 10 is inclined rearward, so that the load falls on the head guard 14. At this time, the head guard 14 is tilted rearward together with the mast 10. Therefore, a backward force is exerted on the luggage dropped on the head guard 14, sliding on the head guard 14 and dropping behind the forklift 1. Therefore, the impact applied to the head guard 14 can be mitigated.

Further, when the forklift 1 is going to travel backward, the operator looks back and moves the forklift 1 backward while looking at the left or right 45 degrees behind the forklift 1. At this time, unlike the conventional case, since there is no pillar 55b that supports the head guard 14, it is possible to surely confirm the rear side, and the forklift 1 can be safely
Can be run backwards.

Further, the fork 11 is raised to a predetermined height, and the mast 10 is tilted forward to the most inclined position. At this time, the head guard 14 tilts integrally with the mast 10. Then, the distance between the head guard 14 and the driver's seat 4 increases. Therefore, the head guard 14 does not interfere with the hoist and the battery can be loaded and unloaded. As a result, it is not necessary to provide a cutout for passing the hoist in the head guard 14, and the unified head guard 14 can be attached to the forklift 1 even if the vehicle types of the forklift 1 are different.

In the forklift 1 of this embodiment,
Mast 1 for moving head guard 14 up and down fork 11
The head guard 14 is tilted integrally with the mast 10. Therefore, even if an obstacle falls on the upper surface of the head guard 14 while the head guard 14 is tilted, the impact can be mitigated, and the design of the head guard 14 can be facilitated.

The present invention is not limited to the above-mentioned embodiments, but may be made as follows without departing from the spirit of the present invention. In the above embodiment, the battery type forklift 1 is applied, but the present invention may be applied to the forklift 1 using an engine or the like.

[0023]

As described in detail above, according to the forklift of the present invention, the mast of the forklift is provided with the head guard disposed above the driver's seat, so that the pillar supporting the head guard is eliminated and the rear field of view is eliminated. Can be improved and rearward confirmation can be reliably performed. or,
When the head guard is tilted backward, even if an obstacle falls on the head guard, the impact can be mitigated, which is an excellent effect.
