Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a technique for installing an auxiliary seat in a small forklift.

[Conventional technology]

Traditionally, forklifts are not equipped with auxiliary seats. However, even on a small forklift, it may be preferable for two crew members to work together on the vehicle.

[Problem that the invention attempts to solve]

If an auxiliary seat is simply added to the engine hood in preparation for two-person work as described above, the weight of the seat will make it difficult to open and close the engine hood, making the opening and closing work risky. Another problem is that the protruding auxiliary seat interferes with the rear pillar of the frame when the engine hood is opened.

The object of the present invention is to enable the addition of seats without affecting the operability when opening and closing the engine hood and without interfering with the rear pillar.

[Means for solving problems]

In the present invention, a pair of brackets are provided on the frame of a forklift at an interval in a substantially horizontal direction, an auxiliary seat is provided on an auxiliary seat stand having an L-shaped cross section, and the auxiliary seat is located at the upper part of the engine hood. The auxiliary seat is equipped with an auxiliary seat, characterized in that the side of the auxiliary seat stand opposite to the auxiliary seat is rotatably supported by the bracket so as to be rotatable around a substantially horizontal axis. The forklift solves the above problems.

[Effect]

When the forklift auxiliary seat of this invention is used as an auxiliary seat, it can be positioned above the engine hood so that two people can work on it, but on the other hand, when servicing the engine compartment, the auxiliary seat can be folded down, completely impairing serviceability. It can be serviced without any problems.

Further, the auxiliary seat of the present invention is provided on an auxiliary seat stand supported by a pair of horizontally spaced brackets, and although the structure is simple, the auxiliary seat is very solid. It's safe.

Furthermore, the auxiliary seat of the present invention can be obtained by attaching the brackets to the frame at approximately horizontal intervals and supporting the auxiliary seat stand. It can also be easily implemented on forklifts.

A long hole 3d is bored in the surface of the auxiliary seat stand 3, and the auxiliary seat 1 is attached so as to be movable back and forth along the long hole 3d, and can be fixed at a desired position by appropriate fixing means. In this way, the auxiliary seat 1
can be slid on the auxiliary seat stand 3 and fixed. This is auxiliary seat 1
This is to adjust according to the physique or sense of the person sitting on the seat.

A hole 3a is bored in the side surface of the auxiliary seat 1, and the hole 3a and the hole 2a of the handrail 2 are fastened together with a bolt 21 (see FIG. 2). The handrail 2 is provided to prevent or protect a person sitting in the auxiliary seat 1 from being thrown off due to centrifugal force when the forklift turns.

Auxiliary seat 1, handrail 2 and auxiliary seat stand 3
is rotatable around a substantially horizontal bar 9 (Fig. 2), and the auxiliary seat 1 is positioned above the engine hood 6 (auxiliary seat position) and removed from the engine hood 6 as shown in Fig. 1. Position (service position)
Furthermore, by removing the bar 9, the auxiliary seat can be removed from the forklift.

In order to fix the auxiliary seat 1 in the auxiliary seat position and the service position, a stopper device is provided on the outside of both brackets 18, respectively.

The stopper device will be explained below. As shown in FIG. 2, a stopper mounting bracket 7 is welded and fixed to the outside of each stand 18 of the auxiliary seat stand 4. As shown in FIG. The pin 23 is connected to the bracket 7.
It is welded and fixed to the end of the machine base.

Stopper mounting bracket 7 and stand 1
Stopper pin mounting holes 7a and 18a pass through the holes 7a and 18a, and the stopper pin 8 is mounted in the holes 7a and 18a. As shown in FIG. 3, the stopper pin 8 consists of a cylindrical head portion and a stopper engaging portion protruding from the head portion, and the stopper engaging portion is divided into two portions 8a and 8c by a partition protrusion 8b. ing. The outer diameter of the partition protrusion 8b is the same as that of the hole 7a, 1.
The outer diameter of the head portion is set slightly smaller than the inner diameter of the hole 8a, and the outer diameter of the head portion is set larger than the inner diameter of the holes 7a and 18a.

A boss attachment part 8d is provided at the tip of the engagement part, and after the stopper pin 8 is installed in the holes 7a and 18a,
Insert the boss 10 with the hole 10b into the boss attachment part 8d, and insert the stop pin 22 into the stop pin holes 10a and 8e.
(Fig. 2) and insert the stopper pin 8 with the stopper mounting bracket 7 and stand 18 in between.
and Boss 10 are integrated.

The outer diameter of the boss 10 is set larger than the inner diameter of the holes 7a, 18a, so that the boss 10 integrated with the stopper pin 8 does not come out of the holes 7a, 18a.

Furthermore, the outer diameter of the head of the stopper pin 8 is made large enough to fit into the stopper pin engagement hole 3b formed in the flange portion of the auxiliary seat stand 3.
