[Problems to be solved by the device]

 The steering wheel operating position of this conventional reach-type forklift vehicle is designed with reference to the driver of average height, and the height of the steering wheel is fixed, so the driver's height is Drivers who are taller or shorter than their height may find it difficult to drive, and in particular, there is a problem that they tend to get tired when driving longer.

The present invention has been made to solve such a problem, and it is a reach type wheel that can move the steering wheel to an optimum height that is easy to operate, regardless of the height of the driver. -For the purpose of providing a steering wheel for a clift car.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the steering handle of a forklift vehicle of the present invention comprises a steering shaft, an outer fitting of the upper end of the steering shaft, a fixed tubular connecting member, and a cylinder. The steering lever is provided with a guide member that is slidably and non-rotatably fitted to the ring-shaped connecting member, and a lock lever having a screw shaft that is screwed into a radial screw through hole formed in the guide member. -Is extended from the guide member.

[0009]

[Action]

 In the steering handle of the reach-type forklift vehicle of the present invention described above, the driver of the forklift can move the steering handle to an optimum height that is easy for him to operate.

[0010]

【Example】

 A steering handle of a reach type forklift vehicle as an embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the connecting member 10 has a flange 10A formed at the lower end thereof and an outer surface provided with a guide (key) 15 extending in the axial direction.

Reference numeral 14 denotes a tubular guide member, and a lower half portion thereof is a guide portion 14a having a thickness slightly thicker than other portions, and a guide groove 14B fitted to the guide 15 is formed on an inner peripheral surface thereof. The guide portion 14a is formed with a radial screw through hole 14A. The guide member 14 is fitted onto the guide 15 at the guide portion 14a, and is fitted onto the connecting member 10 so as to be vertically slidable. The steering lever 12 is fixed to the guide member 14 by externally fitting the lower half portion of the cylindrical head 12A to the guide member 14. Reference numeral 16 is a rock lever having a screw shaft 16A, which is screwed into a screw through hole 14A of the guide member 14 and held by the guide member 14. Others are the same as those in FIGS. 3, 4 and 5.

In this embodiment, when the lock lever 16 is rotated counterclockwise, for example, the screw shaft 16A of the lock lever 16 moves outward in the radial direction of the guide member 14, and the end surface of the screw shaft 16A has a cylindrical shape. Since the guide member 14 can move up and down with respect to the tubular connecting member 10 apart from the connecting member 10, the driver can move the steering lever 12 to an optimum height that is easy for him to operate. .

When the lock lever 16 is rotated in the opposite direction to the above, the screw shaft 16 A of the lock lever 16 moves inward in the radial direction of the guide member 14, and the end surface of the screw shaft 16 A is the outer periphery of the cylindrical connecting member 10. Since the driver presses against the surface, the driver moves the steering lever 12 to an optimum height that is easy for the driver to operate, and then the lock lever 16 is fully rotated to the right to fix the steering lever 12 to this optimum position. can do.

[0015]

[Effect of the device]

 As described in detail above, according to the steering handle of the reach-type forklift vehicle of the present invention, the driver of the forklift can move the steering wheel to the optimum height that is easy for him to operate. As a result, stability is improved.
