Description

[Detailed Description of the Invention] The present invention relates to a steering lever for a skid steer type industrial vehicle.

When driving a skid steer type industrial vehicle, both the left and right steering levers must be operated, and when driving forward, the steering lever must be pushed forward. Therefore, when driving forward for a long period of time, the driver's arms become very fatigued, and even if it becomes necessary to operate the accelerator lever when an excessive load is placed on the climbing board, etc. As is well known, since both hands are pushing the steering lever, it is impossible to manually operate the accelerator lever while driving.

The purpose of this invention is to improve the above drawbacks.
To provide a steering lever for a skid steer type industrial vehicle, in which left and right steering levers are provided with foot levers, and the steering lever can be pushed with both feet via the foot levers.
The present invention will be explained in detail below based on the illustrated embodiments.

In the figure, 1 is a vehicle, 2 is a driver's seat, and on both sides of the driver's seat 2 there are lift arms 3 for vertically moving a bucket 4, and a link between the lift arms 3 and the driver's seat is provided. A guard net 5 for protecting the driver from the lift arm 3 is provided between them. The driver's seat 2 has a steering lever that can be tilted in the front-rear direction to drive left and right wheels via a corresponding hydraulic pump and hydraulic motor (none of which are shown) to drive and steer the vehicle. 6 and 7 are erected through long holes in the floor. The steering levers 6 and 7
, the cylindrical support members 8 and 9 protruding forward at approximately right angles to the steering levers 6 and 7 are located at a position where the soles of the feet or knees of the driver can come into contact with the driver when the driver is seated. Support member fixing hole 6a,
6b, 7a, 7b are drilled, and support members 8, 9 are fixed to the holes. Incidentally, the bases of the support members 8 and 9 are provided with threaded portions, which are passed through the support member fixing holes 6a and 7a and fixed with nuts 24. the support member 8,
A groove 10 is provided in the support members 8 and 9 in the axial direction of the bottom thereof, and a plurality of stoppers 11 are provided in the groove 10 at an angle of about 90 degrees toward the vehicle side. Recesses 12 are provided at appropriate positions in the groove 10 toward the inside of the vehicle.

A cylindrical outer tube 1 is provided on the outside of the support members 8 and 9.
3 and 14 are slidably extended and rotated,
A locking piece 15 is fixed to the end of the outer cylinders 13, 14 on the side of the steering levers 6, 7 so as to fit in the groove 10 and the stopper 11. Foot levers 16 and 17 are fixed to the other end surfaces of the outer cylinders 13 and 14 in parallel with the locking piece 15. Therefore, the rotation range of the foot levers 16 and 17 is symmetrical, and the grooves 10 formed in the support members 8 and 9 are set so that the range of rotation of the foot levers 16 and 17 is symmetrical and is approximately 90 degrees above the horizontal position with respect to the driver's seat in the interior direction of the vehicle. , a stopper 11, locking pieces 15 fixed to the outer cylinders 13 and 14, and the like. However, the locking piece 15 is
When in position 2, it is possible to rotate more than 90 degrees. Reference numerals 16a and 17a are foot levers when pressed with the feet 18 and 19. 20 is the accelerator lever,
21 is the brake pedal, 22 is the dump pedal, 2
3 is a lift pedal.

The present invention has the above-mentioned structure, and its operation will be explained next. If an excessive load is expected during the driving process in the work process to be performed, the foot levers 16 and 17 are respectively tilted inward of the vehicle. At this time, it is necessary to appropriately select the stopper 11 and position the stopper 11 so that the locking piece 15 corresponds to the back surface of the legs 18 and 19 in order to determine the length that is most convenient for the driver. When driving, there is no need to operate the brake pedal 21 or the bucket unless in an emergency, and therefore there is no need to press the dump pedal 22 or lift pedal 23, so when operating the accelerator lever 20, Or, to avoid arm fatigue from operating the steering levers 6 and 7 for a long time, use both feet to move the foot lever 1.
6 and 17 can be operated freely.

However, when driving backwards, the steering levers 6 and 7 must be tilted backwards, so they must be operated by hand. At this time, foot lever 1
Since there is a possibility that the foot levers 6 and 17 may interfere with the driver's feet, it is necessary to raise the foot levers 16 and 17. In addition, when the driver gets on or off the driver's seat 2, since the side of the driver's seat 2 is separated by the guard net 5, the bucket seat 4 can be accessed from the front of the vehicle 1.
Since the driver uses the steering wheel as a stepping stone to get on and off the vehicle, the space between the steering levers 6 and 7 becomes a passage, and therefore,
If the foot levers 16 and 17 are left in use, the driver may trip, so it is necessary to raise the foot levers 16 and 17 respectively when getting off the vehicle. When the foot levers 16 and 17 are raised, the locking piece 15 is moved to the stopper 11 of the groove 10.
If it is in the intermediate position, the foot lever 1 can be moved even while driving.
6 and 17 do not fall horizontally. Furthermore, when the vehicle 1 is stopped, simply raising the foot levers 16 and 17 from the horizontal position causes the locking pieces 15 to fit into the corresponding recesses 12, so the foot levers 16 and 17 can be rotated upward by more than 90 degrees from the horizontal position. It moves and stands up with a slight incline toward the side of the vehicle, so it does not easily fall inward.

As described above, the present invention provides the left and right steering levers, which can be tilted forward and backward, with a foot lever that rotates so as to be able to lock approximately parallel to the levers and approximately horizontally between the levers. The foot lever can be installed up and down in stages and can be extended and retracted so that it comes into contact with the driver's foot when the foot lever is tilted forward. When driving forward, the driver can operate the steering lever using the foot levers with the soles of both feet, which frees up both hands and allows the driver to operate the accelerator lever with his/her hands, as well as fixing the steering lever support member. The foot lever can be supported by the knee by changing its position. Furthermore, since the foot lever can be rotated, it does not interfere with the driver's ability to get on and off the vehicle.
