JPS6212478A - Production of cover for truck bed - Google Patents

Abstract

PURPOSE:To facilitate production of covers fro many types of beds by sorting truck beds per shape and size, forming raw plates for the bottom plate of the bed, side plates and a wheel cover plates, and cutting them off so as to fit the bed then fixing these plates. CONSTITUTION:To produce a cover for a bed of a certain car type, a raw plate for the bottom plate, raw plates for right/left and front/rear side plates, and a raw plate for a wheel cover plate are formed from molds belonging to this car type, and these raw plates are cut off according to the shape and size of the bed. By fixing together the bottom plate 1a, right/left and front/rear side plates 2a-5a and wheel cover plate 6a thus obtained, a cover 7 for bed is completed. Accordingly, covers for beds of all types of trucks can be easily produced by preparing molds for all sections of all types.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a method of manufacturing a cover for the bed of a truck for transporting heavy goods or other vehicles.

(2) Conventional technology to prevent damage to the truck bed, or to use the x8 store on the island of the island! +The bottom plate, left and right side plates, etc. that match the shape and dimensions of the loading platform for each type of space are integrally molded from engineering plastic.

(3) Problems to be Solved by the Invention At present, there are a wide variety of shapes and sizes of truck beds mounted on trucks. It must be integrally molded to match the shape and dimensions of the cargo bed for each vehicle model.
As a result, many types of molds are required, which increases costs, and the cover has the disadvantage of being expensive.

An object of the present invention is to eliminate this drawback and to provide a method for manufacturing a loading platform that allows the loading platform to be manufactured at low cost using fewer types of molds.

(4) Means for solving the problem In order to achieve this object, the present invention classifies truck beds of various shapes and sizes into similar shapes and sizes, and in each classification, the bottom plate of the truck bed with the largest size is The blank plates for the left and right side plates, front and rear side plates, and wheel cover plates are formed, cut to match the shape and dimensions of the truck bed to which these blank plates are applied, and each plate after cutting is fixed to each other. It is a sign of evening.

(5) When manufacturing a rack for a truck bed of a vehicle type, the base plate for the bottom plate, the base plate for the left and right side plates, etc. are formed using molds for each part of the classification to which the vehicle type belongs. The plates are cut to match the shape and dimensions of the bottom plate, left stone side plate, etc. of the loading platform, and the cut plates are adhered to each other to obtain a cover. Therefore, if molds for each part are prepared for each category, covers for truck beds of all types of vehicles can be manufactured, and since the number of molds to be prepared is limited, manufacturing costs can be reduced.

(6) Embodiment An embodiment of the method for manufacturing a loading platform according to the present invention will be described with reference to the drawings.

First, we investigated the shapes and dimensions of various types of truck beds.
Items with similar shapes and dimensions are classified into several types so that they belong to the same category. And for each classification, the bottom plate of the cargo bed of the largest size among the trucks of the vehicle type belonging to that classification,
Manufacture molds for left and right side plates, front and rear side plates, and wheel cover plates.

When manufacturing truck bed covers for vehicle models that belong to the following categories, the molds for the bottom plate, the left side plate, the right side plate, the front side plate, and the rear side plate belong to that category. Using the mold and the mold for the wheel cover plate, as shown in the first diagram, the base plate for the bottom plate (1), the base plate for the left 1 JIJ plate (2), and the right side plate are made of engineering plastic such as carbon mm reinforced plastic (CFRP). blank plate (3), blank plate for front side plate (4
), blank plate for rear side plate (5) and blank plate for wheel cover plate (6)
(6) is molded.

After that, each of these blank plates (1) to (6) is cut as shown in the second diagram to match the shape and dimensions of the bottom plate, left and right steel plates, and front and rear side plates of the truck bed, and each surplus portion is cut. (1b) to (5C) are removed, and the bottom plate (la), left side plate (2a), right side plate (3a), and front side plate (
4a), rear side plate (5a) and wheel cover plate (6a)
(6a) is obtained. Next, these plates (1a) to (6a) are glued together with an adhesive to form a cargo bed cover (7a) as shown in Figure 3.
) is obtained.

Also, when manufacturing truck bed covers for vehicle models that belong to other classifications, use the mold of that classification to form the base plate for the bottom plate, etc., and then manufacture the loading bed cover using the same procedure as described above. However, if the cover is made of a metal plate such as stainless steel, each side plate etc. should be fixed by welding. Further, the above-mentioned cutting may be performed on the upper protrusion side of the blank plate of each side plate.

(7) Effects of the Invention As described above, according to the present invention, truck beds of various shapes and sizes are classified into similar shapes and sizes, and in each classification, the bottom plate, left and right side plates, and front and rear side plates of the largest size of the truck bed are classified. We prepared molds for wheel cover plates, used these molds to mold the blank plates of these plates, and manufactured covers by adhering each plate of the truck to which these blank plates were applied. By preparing a limited number of molds for each part of the sword bar for each category, covers can be made for any type of truck bed, making it versatile, and moreover, it can be used for a large number of car types as before. It is not necessary to prepare a mold for each truck bed, which has the effect of reducing manufacturing costs.
