Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a driver's seat for a forklift.

[Conventional technology]

An exercise seat is known in which side support members are provided on both sides of the operator seat to prevent the operator from jumping out from the operator seat when the forklift overturns.

[Problem that the invention attempts to solve]

In such a driver's seat, the side support members are fixed to the frame of the operator seat, so the side support members may get in the way when the operator gets on and off, or the position of the side support members may vary depending on the size of the operator. The operator may not be able to be held securely due to inadequate support, or the side support members may become a hindrance and become difficult to operate.

Therefore, an object of the present invention is to provide a driver's seat for a forklift that can solve the above problems.

[Means and effects for solving the problem] A side support member is attached to a pair of left and right rear legs of the head guard located on both left and right sides of the operator seat, at a position facing the front of the vehicle body and a position facing the side of the vehicle body. In addition to being rotatably mounted, a ratchet wheel fixed to the center of rotation of the side support member and a ratchet pawl attached to the rear leg act as a locking mechanism that restricts or allows rotation, and is placed on the side when the operator gets on and off. The side support member can be positioned toward the side of the vehicle body so that it does not get in the way, and it can also be rotated to a position that matches the size of the operator's physique.

〔Example〕

As shown in FIG. 1, an operator seat 2 is attached to a vehicle body 1, and a head guard 3 is attached so as to surround the front, rear, left and right sides of the operator seat 2.
4 and a pair of rear legs 5, 5, the pair of rear legs 5, 5 are located at intervals on both left and right sides of the rear part of the operator seat 2, A pair of left and right side support members 7, 7 are respectively attached to the pair of rear legs 5, 5 so as to be rotatable in the left and right direction. In other words, the side support member 7 is a support frame 8 formed by bending a round bar into a rectangular shape as shown in FIG.
A protective pad 9 is attached to one vertical portion 8a of the bracket 1.
0, the bracket 1 is attached so as to be rotatable left and right, and the other vertical portion 8b of the support frame 8 is attached to the rear leg 5.
It is rotatably inserted into the vertical hole 11a of No. 1.

A rotation lock mechanism 12 is attached to the other vertical portion 8b of the support frame 8 and the rear leg 5. The rotation lock mechanism 12 includes a ratchet wheel 13 fixed to the lower part of the other vertical portion 8b, a ratchet pawl 16 supported on the bracket 11 by a vertical pin 14 so as to be rotatable left and right, and provided with an operating lever 15.
It is composed of a spring 17 that rotationally urges the ratchet pawl 16 to engage with the ratchet wheel 13, and the ratchet wheel 13 is moved away from the operator seat 2 by the ratchet pawl 16 as shown in FIG. 3 (in the direction of the arrow). The rotation of the side support member 7 in the direction away from the operator seat 2 is restricted as shown by the arrow in FIG. 17 and rotate in the direction away from the ratchet wheel 13, the side support member 7, that is, the support frame 8 provided with the protective pad 9 can be rotated in the direction away from the operator seat 2, and the side support member 7 can be rotated to a position facing the side of the vehicle body 1.

Therefore, when the operator gets on and off the operator seat 2, the side support member 7 can be rotated to a position facing the side of the vehicle body 1 as described above, so the side support member 7 does not get in the way. .

Furthermore, when the operator's hand is released from the operating lever 15, the ratchet pawl 16 engages with the ratchet wheel 13 by the spring 17, thereby restricting the rotation of the support frame 8 in the direction away from the operator seat 2. Not only can the support frame 8 be held in the forward position of the operator seat 2 to prevent the operator from jumping out from the operator seat 2 in the event of the vehicle overturning, but the support frame 8 can also be rotated together with the protective pad 9 in a direction toward the operator seat 2. 9 can be rotated to a position suitable for the size of the operator's physique, the operator can be surely supported regardless of the size of the physique, and the protective pad 19 does not get in the way.

Note that the support frame 8 is urged by a spring to rotate in a direction away from the operator seat 2, and the ratchet wheel 13 is pressed and held against the ratchet pawl 16.
The protection pad 9 and the support frame 8 may be prevented from swinging, the protection pad 9 may be directly supported on the rear leg 5, or the support frame 8 alone may be used as the side support member 7.

[Effects of the invention] When the vehicle falls over, the side support member 7 prevents the operator from jumping out from the operator seat 2, and the operator can move the operator from the side by holding the operation lever 15 and detaching the ratchet pawl 16 from the ratchet wheel 13. Since the support member 7 can be rotated to the side of the vehicle body, the side support member 7 can be easily rotated to a position toward the side of the vehicle body where it does not get in the way when the operator gets on and off, so that the operator can easily get on and off the vehicle. Moreover, by rotating the side support member 2 in the left-right direction and changing the engagement position between the ratchet wheel 13 and the ratchet pawl 16, the side support member 7 can be placed in a position suitable for the size of the operator's physique. This allows operators of different physiques to reliably prevent the vehicle from falling out when it falls over, and it does not get in the way during operation.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and FIG. 1 is an overall front view, FIG. 2 is a perspective view of the mounting portion of the side support member, and FIG. 3 is a plan view of the ratchet wheel portion. 1 is a vehicle body, 2 is an operator seat, 3 is a head guard, 5 is a rear leg, 7 is a side support member, and 12 is a lock mechanism.

Claims (1)

[Scope of utility model registration request] A pair of left and right rear legs 5, 5 of the head guard 3 are positioned on both left and right sides of the operator seat 2 attached to the vehicle body 1, and a pair of left and right lateral support members 7 are placed on the left and right pair of rear legs 5, 5 at the front of the vehicle body. The side support member 7 is attached so as to be rotatable in the left and right directions, and a ratchet wheel 13 is fixed to the center of rotation of the side support member 7, and the ratchet wheel 13 is engaged with the ratchet wheel 13. In addition, a ratchet pawl 16 equipped with an operating lever 15 is attached to the rear leg 5, and the ratchet pawl 16 is engaged and biased with the ratchet wheel 13 by a spring 17 to form a rotation locking mechanism 12.
