A remote-controlling Bowden cable 14 is installed in the power unit 7, apart from an actuating lever 9 actuating a flow passage selecting spool built in an operating part 8. The Bowden cable 14 is supported on a bracket 18 being projectingly installed in a lower side part of the outer post 3a, and simultaneously made to go along a side face of the outer post 3a toward the upper part whereby it is detachably attached to a clamp 19 installing the cable upper side part tight to the post 3a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lifting/lowering operating device for a rear gate lifter disposed at the rear end of a truck deck.

In order to improve the efficiency of cargo handling operations at the rear end of a deck, it is known that a conventional truck is configured with a rear gate lifter in which the rear gate can be raised and lowered.

As shown in FIG. 1, this consists of an outer boss (3a) fixed to the deck 2 on both sides of the rear end of the deck 2, and an inner boss (3b) fitted into the outer boss (3a) so as to be vertically slidable.
A rear gate 4 is rotatably mounted via a hinge member 6 to a lift bracket 5 fitted to the inner post 3'b so as to be vertically slidable, and the rear gate 4 is rotatably mounted on the rear side of the vehicle body 1. The rear gate 4 is raised and lowered by means of a drive transmission means such as a wire or chain (not shown) using a power unit 7 disposed at the rear as a drive source.

A hydraulic device is used for the power unit 7, and an operating lever 9 that operates a spool (not shown) built into an operating portion 8 is rotated upward or downward as shown by an arrow, for example, to operate the rear gate 4 to raise or lower it. It has become. 10 is a mounting bracket for the power unit 7, 11 is an outer mast 3
This is a reinforcing member that straddles the lower end of a and the side of the vehicle body 1.

However, with this conventional structure, when raising and lowering the ladder gate lifter, the operator must either get off the deck 2 to the ground and operate the actuating lever 9, or bend forward on the deck 2 and operate the actuating lever 9. There is always a problem with the lack of convenience. Moreover, when handling unstable cargo, when a worker must ride on the liftgate 2 to support the cargo, it is extremely difficult and dangerous for the worker to operate the actuating lever 9 by himself. there were.

Therefore, as shown in Japanese Utility Model Publication No. 55-83132, a box 2 arranged on the rear side of the vehicle body is provided with a remote control switch that can be housed and pulled out freely, and this remote control switch is used to operate the lifter of the rear gate lifter. It has been proposed to do this, but
In this case as well, when performing remote control using the remote control switch, the worker must first go down to the ground and take out the remote control switch from the box, or the operator may If it becomes necessary to perform a lifting or lowering operation, the operator must descend to the ground again and perform the operation, and the convenience cannot be improved as much as expected. In addition, in order to operate the power unit electrically using a remote control switch, electrical parts such as an electromagnetic actuator are required for the operation section of the power unit, which increases costs and increases the frequency of failures, which is a new problem. will occur.

Purpose of the Invention In view of the above problems, the present invention provides a lift gate lifter that can be easily operated from any position on the ground, on a deck, or on the rear gate, and that is structurally simple and can reduce costs. The purpose is to provide an operating device.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes guide posts erected on both sides of the rear end of the deck, and a rear gate that is guided up and down by the guide posts using a power unit disposed on the side of the vehicle body as a driving source. The power unit has a structure in which an operating lever and a Bowden cable for remotely controlling the operating part are provided in the operating part of the power unit. Examples Hereinafter, embodiments of the present invention will be explained together with drawings and the conventional configuration. The same parts will be described in detail with the same reference numerals.

In the embodiment shown in FIG. 2, a bridge plate 12 in which a step hole 1.2a is formed is used as the reinforcing member 10, and this bridge plate 12 is connected to the rear side of the vehicle body 1 and the guide post. The power unit 7 is installed on the back side of this bridge plate 12.

This power unit 7 is provided with a Bowden cable 14 for remote control in addition to an operating lever 9 that operates a flow path switching spool (not shown) built into the operating section 8. The Bowden cable 14 consists of an inner wire 15 and an outer tube 16 made of a flexible part that slidably covers the inner wire 15. In this embodiment, one end of the inner wire 15 is connected to the casing of the power unit 7. The operating section 8 is remotely controlled by a push-pull operation of a knob 17 provided at the other end of the inner wire 15, which is connected to an extending knob section 13 of a spool (not shown) that projects outward. In addition, this Bowden cable 14 is supported by a bracket 18 protruding from the lower side of the outer boss 3a, and is placed upward along the side surface of the outer boss 3a, with the upper part of the cable fixed to the outer boss 3a. It is detachably attached to the clamp 19.

According to the above embodiment structure, when lifting and lowering the rear gate 4 for cargo handling work, the rear gate 4 is raised and lowered by operating the operating lever 9 when it is on the ground, and when it is on the deck 2, the rear gate 4 is raised and lowered by operating the operating lever 9. Le 14 Outabost 3a
While it is attached to the outer boss 3a, or by removing it from the outer boss 3a, push and pull the knob 17 to install the power unit 7.
The rear gate 4 can be raised and lowered by remotely controlling the operating section 8 of the vehicle.

Furthermore, when handling unstable cargo, if the worker lifts or lowers the liftgate 4 while supporting the cargo on the liftgate 4, the Bowden cable 14 should be used in the same way as when operating on the deck 2. The operating portion 8 can be easily raised and lowered while being attached to the outer post 3a, or by removing it from the outer post 3a and remotely controlling the operating portion 8 using the Bowden cable 14.

Here, the inner wire 15 of the Bowden cable 14
may be connected to an operating lever 9a of the operating section 8 as shown in FIG. In this case, the operating lever 9a is formed in an abbreviated shape, so that even when the operating V-bar 9a is gripped and operated, the inner wire 15 of the Bowden cable 14 does not get in the way. Also, bracket 1
Outer tube 16 extending from 8 toward the actuating lever 9a side
a also serves as a guide for the inner wire 15, and the outer tube 16a itself has rigidity and is difficult to bend, but is swingable at the mounting part of the bracket 18, so that it follows the arcuate trajectory of the operating lever 9a, The inner wire 15 is prevented from buckling.

Therefore, in this embodiment, the operating lever 9a is
On the deck 2 or on the rear gate 4, the operating lever 9a is remotely operated using the Bowden cable 14 to raise and lower the rear gate 4.

In addition, the Bowden cable 14 is fixed to the upper end of the outer boss hb (boss) 3a as shown in FIG.
The knob 17 may be disposed protruding from the upper end of the knob 17 and remotely operated by a bush pull of the knob 17 on the deck 2 or on the rear gate 4.

In this embodiment, since the Bowden cable 14 is protected by the outer post 3a, durability can be improved.

Effects of the Invention As described above, according to the present invention, there are two types of operation: direct operation using the operating lever of the operating section and remote control using the Bowden cable, so the device can be operated in any position on the ground, on the deck, or on the rear gate. However, the operator can easily raise and lower the rear gate without taking an unreasonable posture, further increasing cargo handling efficiency and improving safety. Furthermore, unlike remote control switches, this method does not require any electrical parts, so there is no increase in cost, and it can be easily applied to existing devices, which has great practical effects.
