Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a gate panel for a truck bed, and more particularly to a gate panel made of synthetic resin.

[Prior Art] As a gate panel such as a side gate panel or a tail gate panel of a truck carrier, one integrally molded with a synthetic resin is used. In addition, in this type of gate panel, a metal top rail for reinforcement is generally provided along the upper end of the gate panel.

The top rail is attached to a panel body that has been molded in advance. 3 and 4 show a typical example of a top rail mounting structure in a conventional synthetic resin loading platform gate, in which a molded synthetic resin panel main body 1 has a recess having a U-shaped cross section along its upper end. With 11
The wall surface of the recess 11 has protrusions 12 at predetermined intervals, and the top rail 2 made of metal is fitted into the recess 11.
Holes 20 are formed in the top rail 2 at positions corresponding to the protrusions at predetermined intervals, and the protrusions 12 are formed in the holes 20.
The top rail 2 is fixed in the recess 11 by inserting the through hole and caulking the protruding end of the protrusion 12. The top rail 2 may be bolted to the recess 11. Then, the recess 11 is closed by the cover member 3, and the cover member 3 is fixed to the panel body 1 or the top rail 2 by screwing or the like, whereby the top rail 2 is attached.

[Problems to be Solved by the Present Invention] However, in the cargo bed gate having the above-described top rail mounting structure, peeling may occur partially between the upper edge of the cover member 3 and the end surface of the panel body 1 joined thereto. is there. Further, when the luggage carrier vibrates, a squeak noise may be generated between the panel body 1 and the top rail 2 in contact therewith.
Further, there is a problem that it takes a lot of time to attach the top rail 2 to the panel body 1.

Therefore, an object of the present invention is to provide a cargo carrier gate panel which does not cause the above-mentioned peeling and squeaking noise and requires a small number of manufacturing steps.

[Means for Solving the Problems] In the gate panel of the present invention, a panel body and a top rail embedded along the upper end of the panel body are integrally formed at the same time.

And this gate panel, for example, set the top rail in the cavity of the mold for molding the gate panel,
It is obtained by molding a synthetic resin.

[Effect] In the gate panel of the present invention, the resin material of the panel body wraps around the top rail and is crimped together, so that the two are integrated and do not move relative to vibrations. No sound is produced. Also, since both are integrally molded, the number of manufacturing steps is small.

[Embodiment] In the embodiment shown in FIGS. 1 and 2, the panel body 1 made of synthetic resin is hollow as a whole, and has reinforcing ribs 13 connecting the front and rear wall surfaces thereof. . In addition, a reinforcing top rail 2 made of metal is embedded along the upper end in the panel body 1.

The top rail 2 has a spectacle-like cross-section and has closed cross-sections at the top and bottom, and is formed by superposing and welding two bent metal plates at both ends and the central part.

Holes 20 are formed in the central overlapping portion at predetermined intervals in the longitudinal direction of the top rail. Extension portions 22 and 23 are formed at the edges of one metal plate from the overlapping portions at both ends.

The top rail 2 and the panel body 1 are held by the resin wrapped around by setting the top rail 2 in a molding die and blow molding the panel body 1. As a result, at the upper end of the gate panel, the upper and lower surfaces of the top rail 2 and the side surface outside the vehicle are integrated with the synthetic resin material of the panel body 1. Particularly, in the central portion of the side surface of the inside of the top rail 2 on the inside of the vehicle, the resin material is wound around the hole 20 toward the back side to strengthen the coupling, and the extension portions 22 and 23 are provided.
May be strengthened to form a bond. Then, the target gate panel is obtained by closing the upper vehicle inner surface of the panel body 1 in which the top rail 2 is embedded with the cover member 3. The cover member 3 can be fixed by, for example, thermocompression bonding the upper and lower edges thereof to the edge of the panel body 1.

In the gate panel of the present invention, the panel body 1 is
Since the synthetic resin material is integrated on the entire joint surface with the top rail 2, it does not come off from the top rail 2. Further, even if vibration is applied to the luggage carrier while the vehicle is running, the panel body 1 and the top rail 2 are integrated and do not vibrate relative to each other, so that no squeak or friction noise is generated between them. And,
The number of manufacturing steps can be reduced as compared with the conventional case where the top rail 2 is attached to the panel body 1 afterwards.
