[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a hook type side shift device applied to a cargo handling vehicle such as a forklift.

[0002]

2. Description of the Related Art Conventionally, as this kind of side shift device, for example, the one shown in FIG. 4 is known. The side shift device 50 basically includes an elevating body 51, a horizontally moving body 52 provided on the front side of the elevating body 51, and a laterally moving cylinder 53 for laterally moving the horizontally moving body 52 with respect to the elevating body 51.
And a hook 54 provided above the elevating body 51 and a hook 55 provided above the horizontal moving body 52 and hooked on the protrusion 54 so as to be able to move laterally. The elevating body 51 is
It comprises left and right lift brackets 56 and upper and lower finger bars 57 provided on the front side thereof. Ridge 5
4 uses the ridge formed on the upper finger bar 57 of the elevating body 51 as it is. Thus, when the lateral cylinder is operated, the lateral body can be laterally moved, that is, side-shifted with respect to the elevating body. However, such a thing can use the ridge of the upper finger bar of the elevating body, but since the ridge and the hook hooked on it are located at the upper position, the disadvantage that the front view is bad is bad. there were.

[0003]

[Problems to be solved by the present invention] The present invention has been made in view of the above-mentioned problems, and has been developed to solve the above problems. In providing the device.

[0004]

The side shift device according to the present invention basically includes an elevating body, a laterally movable body provided on the front side of the elevating body, and a laterally movable body with respect to the elevating body. A horizontal cylinder to be traversed, a downwardly protruding ridge provided in the middle of the traversing body, and a hook body provided in the middle of the lifting and lowering body so that the ridge can be traversed. There is a characteristic.

[0005]

When the horizontal cylinder is operated, the horizontal body is moved laterally with respect to the elevating body. Since the downward projecting ridge is provided at the middle position of the horizontal moving body, and the hook body at which the projecting ridge is hooked so as to be able to traverse is provided at the middle position of the elevating body, the front view is enlarged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional side view showing a side shift device according to a first embodiment of the present invention. Side shift device 1
The main part is composed of a lifting / lowering body 2, a lateral moving body 3, a laterally moving cylinder 4, a ridge 5, and a hook 6, and is applied to a cargo handling vehicle such as a forklift. The elevating body 2 serves as a base of the side shift device 1. In this example, the elevating body 2 is used for a mast device, and includes left and right lift brackets 7 and upper and lower finger bars 8 provided on the front side thereof. Consists of End rollers 9 are pivotally mounted on both lift brackets 7. The horizontal moving body 3 is provided on the front side of the elevating body 2 so as to be able to move laterally. In this example, the horizontal moving body 3 includes upper and lower finger bars 10 and left and right connecting plates 11 provided therebetween. The laterally moving cylinder 4 is for moving the laterally moving body 3 laterally with respect to the vertically moving body 2, and is interposed between the left lift bracket 7 of the vertically moving body 2 and the right connecting plate 11 of the horizontally moving body 3 in this example. ing. The ridge 5 is the horizontal moving body 3
In this example, it is formed below the upper finger bar 10 of the horizontal moving body 3.
The hook 6 is provided at the middle position of the elevating body 2 so that the ridge 5 can be slidably traversed. In this example, the hook body 6 has a substantially J-shaped side surface, and is located on the front side of the upper finger bar 8 of the elevating body 2. And hooked on the ridge 5. A cargo handling device 12 is provided on the front side of the horizontal moving body 3 so as to be able to move laterally. In this example, the cargo handling device 12 is a left and right fork, and is suspended on the finger bar 10 of the horizontal moving body 3 so as to be able to move laterally. Between the ridge 5 and the hook 6, the lower finger bar 8 of the elevating body 2 and the horizontal moving body 3
Between the lower finger bar 10 and the upper and lower
Is interposed. The upper smooth body 13 is a bush in this example, and is provided below the ridge 5. The lower smooth body 13 is a bush in this example, and is provided on the front side of the lower finger bar 8 of the elevating body 2. Next, the operation will be described based on such a configuration. The ridge 5 is hooked on the hook 6 via the upper smooth body 13, and the lower finger bar 10 of the horizontal moving body 3 is engaged with the lower finger bar 8 of the elevating body 2 via the lower smooth body 13. The horizontal moving body 3 is supported by the elevating body 2 so as to be able to move laterally. When the lateral cylinder 4 is operated, the lateral body 3 is laterally moved with respect to the elevating body 2. A downwardly protruding ridge 5 is provided in the middle of the horizontal moving body 3 and a hook 6 on which the ridge 5 is hooked so as to be able to traverse is provided in the middle of the elevating body 2, so that the front view is reduced. It is enlarged. That is, the front view from the viewpoint A is expanded from the conventional two-dot chain line to the solid line of the present invention.

Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the elevating body 2 is composed of left and right lift brackets 7, hooks 6 provided on the front upper portions thereof, and plates 14 provided on the lower front portions of both lift brackets 7, and The first embodiment differs from the first embodiment in that the finger bar 8 is omitted and a bush that is a smooth body 13 is provided on the plate 14. In such a configuration, the front overhang is reduced by the amount of omitting the finger bar 8 as compared with the first embodiment, and the front field of view is enlarged, so that the cost can be reduced. When the front overhang is reduced, the allowable load can be increased and the turning radius can be reduced.

Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment is different from the second embodiment in that the hook 6 is provided between the upper portions of the lift brackets 7 and the plate 14 is provided between the lower portions of the lift brackets 7. In such a case, the front overhang is further reduced and the front view is expanded by the distance between the hook 6 and the plate 14 from the front side of the lift bracket 7 as compared with the second embodiment.

In the above embodiment, the lifting body 2 is used for a mast device. However, the invention is not limited to this. For example, it may be used for a boom device. Cargo handling equipment 12
In the above embodiment, the left and right forks are used. However, the present invention is not limited to this. For example, a ram or bucket may be used. Smooth body 1
Reference numeral 3 is a bush in the above embodiment, but is not limited to this, and may be, for example, a roller.

[0010]

[Effects of the Invention] As described above, according to the present invention,
The following excellent effects can be obtained. (1) Consists of an elevating body, a horizontal moving body, a laterally moving cylinder, a ridge, and a hook. Particularly, a downwardly protruding ridge is provided in the middle of the horizontal moving body, and the ridge can be traversed in the middle of the elevating body. Since the hook is hooked on the front side, the front view can be improved. (2) A downward projecting ridge is provided in the middle of the horizontal
Since the hook is provided at the middle position of the elevating body so that the ridge can be slidably moved, there is no danger of collision with other objects and damage.
