Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a wing type hood that covers a truck bed.

[0002]

[Prior Art]

 As a kind of hood that covers the truck bed, both side wall plates of the hood rotate around an axis provided on the roof parallel to the running direction of the vehicle and jump upwards, which is convenient for loading and unloading the cargo bed. The ones that are used are often used. This type of hood is called a wing type because the opening and closing of its side wall is similar to opening and closing the wings of a bird, and its side wall is also called a wing.

As shown in FIGS. 3, 4 and 5, which show a conventional example, the usage of this wing type hood is supported by the gate-shaped frame columns 10 and 11 and the central beam 12 provided in the front and rear portions of the luggage carrier. In addition, the vertical side wall 2 of the wing 1 does not cover the entire side surface of the cargo bed 20, but covers the side wall of the cargo bed in combination with the tilt 3, which has a certain height that rises by a hinge.

[0004]

[Problems to be solved by the device]

 In the conventional wing type hood described above, when loading and unloading a load, the door 4 at the rear of the hood is opened and a predetermined latch is removed, and the hydraulic operation button is pressed to activate the hydraulic cylinder 5 to move the front and rear portions of the wing 1. Push up on the back side and flip up wing 1 as shown by the arrow in Figure 4. After that, further remove the latch of the tilt 3 and hang it downward as shown in FIGS. 4 and 5. Thus, the platform is released and the loading and unloading is free.

By the way, such large trucks are often bulky or heavy, and are generally loaded and unloaded by mechanical force such as forklift trucks. In other words, there is often only one driver to operate the wings and tilt. The wing operation is hydraulic with buttons, so there is no problem, but Aori has a comparable weight and opening and closing work by one person requires a considerable amount of effort.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and according to the present invention, the above-mentioned tilt is separated from the cargo bed and hung at the tip of the wing. The reason why the wing was not extended by the amount of flapping was to limit the width of the wing that was flipped up to the left and right. The present invention further folds the wing with the wing flipped up (hereinafter referred to as the lower wing) so that it can be folded to the lower side of the wing so as not to obstruct the passage for loading and unloading the load. And a device for pulling the wire that has been laid to the side.

[0007]

[Action]

 Separate the lower wing from the platform and activate the hydraulic cylinder to push the wing to the left and right side of the vehicle. Since the lower wing is rotatably attached to the tip of the wing, the lower wing is lifted up at the same time as the wing is opened, and as the wing opens, it is pulled by the wire and folded inside the wing.

[0008]

【Example】

 FIG. 1 shows an essential part of the present invention, in which only one side of the wing is seen from the rear of the truck bed, and the same configuration actually appears symmetrically.

In FIG. 1, a lower wing 3 is attached to a lower end portion of a side wall 2 of a wing 1 rotatably attached to a central beam 12 by a hinge 6. A wire retainer 30 for connecting the wire 35 is provided at a portion near the rear edge of the lower wing 3. The wire 35 whose one end is fixed to the wire retainer 30 is a gate frame pillar via a pulley 31 provided near the ceiling of the wing on the back side of the side wall 2 and a pulley 32 provided near the side wall 2 on the back side of the ceiling. The other end is fixed to a predetermined position 33 of the horizontal beam 21. Therefore, the entire wire is moored under tension.

Next, the operation when the wing 1 is operated from the closed state of the wing to the open state of the wing 1 shown by the chain line will be described. First, 3'indicates a state in which the lower wing 3 is pushed up when the wire 35 is not present and is hung from the lower end of the side wall 2 of the wing 1 by the hinge 6. Due to this sagging, the spread width of the wing I when it is in the open state is the same as in the conventional example, and obstacles such as utility poles and street trees can be avoided when loading and unloading work on narrow roads. .

The state of the lower wing 3 ′ shown by the dotted line shows a case where the lower wing is closed by the wire 35. As described above, since the length of the wire 35 is tensely stretched from the connecting point of the wire stay 30 to the mooring point 33 in the state where the wings are closed as described above, the length of the pulley 31 from the wire stay 30 is , B is the length from the pulley 31 to the pulley 32, and C is the length from the pulley 32 to the mooring point 33, which are represented by A + B + C.

The length relationship between the points involved in the wire after the wing has been opened will be described. When the length between the wire stay 30 and the hinge 60 is a, the length of the wire between the points 30 'and 31' after the movement is A- (2 × a), the total length of the wire is A + B. Since + C is the same as B between point 31 'and 32', it is necessary to set the distance between point 32 'and mooring point 33 to C + 2a. Here, the fact that the dimensions of points 31 and 32 before and after the movement are constant indicates that the dimension can be zero, that is, one pulley can be used.

The above-described structure is provided in the front and rear portions of the wing 1 along the gate-shaped frame columns 10 and 11, respectively, one pair on each side. As for wiring, as described above, two pulleys shown in Fig. 1 may be used or only one pulley may be used. However, in the case of one, the intimate contact of the lower wing to the inside tends to be somewhat lost. However, the same effect as when two or more than two is obtained. If desired, a pulley can be installed between points 30 'and 31' in FIG. 1 to increase the inward closeness of the side wall 2'of the lower wing 3 '.

FIG. 2 is a partial view of an essential part showing a second embodiment of the present invention. In this embodiment, the wire pulling device of the first embodiment uses the difference in stroke between guide points of the wire, but instead of using the 90-degree rotation of the wing shaft support, the wire 35 A winding wheel 37 having the other end fixed is used. In this case, the rack wheel 36 and the driven gear train that rotate together with the wing shaft support are set so that the outer peripheral rotation stroke of the hoisting wheel 37 becomes 2a. Further, the hoisting wheel 37 can be driven by a piston structure using a hydraulic cylinder.

In FIG. 1, reference numeral 22 is a wing holder into which the lower end of the lower wing 3 is fitted when the wing 1 is closed, and the upper opening is opened outward to facilitate fitting. Have. The wing receivers 22 are provided at a plurality of places as required. Further, this wing holder may be slidably attached downward, and may have a structure in which after the lower wing hangs, it is lifted and clamped and fixed to the side of the bed.

[0016]

【effect】

 Since the present invention is configured as described above, firstly, the conventional tilt is rotatably attached to the tip of the wing, and the wing is hydraulically lifted and simultaneously lifted up. Can be omitted.

Secondly, as the wing 1 is opened, the lower wing is pulled by the wire and folded inside the side wall of the wing, so that the degree of opening of the side surface of the bed is increased, and there is no obstacle particularly at the upper side.

Thirdly, although a structure for attaching a tilt has been conventionally provided at the edge of the cargo bed side, the present invention allows the lower wing to be pressed from the outside, so that the width of the cargo bed can be widened.
