Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a waterproof covering device for the central part of the roof of an L-shaped roof panel of a fully-opening truck.

(Prior Art) As shown in Fig. 2, the structure of a conventional waterproof cover is such that a waterproof cover made of canvas (hereinafter referred to as a waterproof cover) is placed between the reinforcing members 12 and 12 to which the hinges 20 of the left and right roof panels 7 are attached. 14 is attached with rivets 15, etc. According to this structure, the roof surface material 1
3 and the edges of the waterproof cover 14 are fixed to the upper surface of the reinforcing member 12 in a watertight manner. Therefore, the hinge piece 20 of the hinge 20
a and 20b had to be attached to the central support shaft 8 and the side of the reinforcing member 12 by welding. The gap between the central support shaft 8 and the reinforcing member 12 is determined by the size of the hinge, but in any case it is not as wide as the one on the left.
Therefore, welding the hinge pieces 20a and 20b was not easy. As vehicles became larger, the length of the hinges also increased, making it even more difficult. In addition, with such a structure, the waterproof cover and the hinge are in constant contact with each other, so there is a risk of damage to the waterproof cover, and an improvement has been desired.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the prior art, and includes the installation work of the hinge 20 interposed and fixed between the central support shaft 8 and the edge support member 12'. The purpose is to completely separate the waterproof cover 14 and the hinge 20 and prevent the waterproof cover 14 from being damaged due to frictional phenomena.

(Means for solving problems by invention) A front wall installed in front and behind the loading platform floor, a rear door frame,
In the roof retractable freight vehicle in which a pair of L-shaped roof panels pivoted approximately symmetrically at the upper center of the front wall and the rear door frame can be raised and lowered, the front wall and the rear door frame;
Attach a hinge piece for an L-shaped roof panel pivot to each top surface of the central support shaft attached between the tops of the rear door frame and the edge support members of the pair of L-shaped roof panels, and Each of the L-shaped roof panels is rotatable with respect to the central support shaft, and a waterproof cover that covers the central support shaft and the edge of the L-shaped roof panel is attached to the central support shaft and the L-shaped roof panel. It was installed at a distance above the top of the molded roof panel.

(Function) Since the hinge pieces 20a and 20b of the hinge 20 can be fixed to the upper piece 12'a of the edge support member 12' on the top surface of the central support shaft 8, the welding work is facilitated, and Since the waterproof cover 14 and the hinge 20 are separated from each other, it is possible to prevent damage thereto.

(Example) FIG. 1 shows a trailer with an opening/closing roof in which the present invention is implemented. 1 is the loading platform floor, and the front wall 2 is in front and behind it.
However, at the rear, a rear door frame 4 with a rear door 3 is attached to the floor 1.
It is installed perpendicularly to the Reference numeral 5 denotes side fans provided on both sides of the floor 1, which can be opened and closed laterally using hinges 6. Now, the cross section of 7 is L
It is a shaped roof panel. This L-shaped roof panel 7 is attached to both sides of a central support shaft 8 attached between the front wall 2 and the top of the rear door frame 4 by hinges 20 so that it can be opened and closed in the vertical direction. 9 is a hydraulic device that opens and closes the L-shaped roof panel 7.

The L-shaped roof panel 7 is constructed by aligning L-shaped auxiliary aggregates 11 at regular intervals between the L-shaped outer frames 10, 10, and fixing reinforcing members 12 in the right angle direction to these by welding or the like. Furthermore, a surface material 13 such as an aluminum plate is stretched over its outer surface.

The present invention relates to a waterproof cover near the part indicated by the arrow A, that is, the central support shaft 8 of such a trailer with an opening and closing roof. This will be explained in detail with reference to FIGS. 3 and 4.

In FIG. 3, 12' is the L-shaped roof panel 7,
In the improved edge support member No. 7, an L-shaped piece 12'b is integrally provided on the upper piece 12'a of the base, which has a round-shaped cross section, and has a round-shaped cross section as a whole.
Reference numeral 20 denotes a hinge for rotatably connecting the edges of the L-shaped roof panels 7, 7 and the center support shaft 8, and the hinge pieces 20a, 20b connect the top surface of the support member 12' and the center support shaft 8. 8 is fixed to the top surface of each. A waterproof cover 14 is fixed with rivets 17 to the top surface of the flange 16 of the L-shaped piece 12'b of the support member 12'.

FIG. 4 shows the structure of the front and rear ends of the waterproof cover. 18 bends the edge of the waterproof cover at right angles,
This is a fixing plate for fixing the waterproof cover to the end of the flange 16 and the outer frame 10. 19 is a cut in the center of the waterproof cover 14, which allows the L-shaped roof to be opened and closed smoothly.

(Effects) According to the present invention, 1. Since the hinge pieces 20a and 20b of the hinge 20 are attached to the top surfaces of the support shaft 8 and the support member 12',
Its installation became very easy.

2. Since the waterproof cover 14 is spaced apart above the support member 12' and the central support shaft 8, the work of attaching the hinge has become very easy.

3. Since the waterproof cover 14 and the hinge 20 are always separated, damage to the waterproof cover 14 due to friction phenomena can be prevented.
