Abstract

PURPOSE:To assemble a fixing body simultaneously with the forming of a gutter supporter by previously forming the fixing body having a special shape together with a holding plate, and setting the holding plate in a mold for forming the gutter supporter, to form the gutter supporter of synthetic resin. CONSTITUTION:A fixing body A is formed of synthetic resin so as to be one body with plural engaging concave parts 1, a holding plate 2, a supporting hole 3, a fixing plate 4 and fixing holes 5. A forming mold for a gutter supporter B is composed of a base end 7, engaging convex parts 8 and a fitting groove 9. The engaging concave part 1 and the holding plate 2 of the fixing body A are then set in the engaging convex part 8 and the fitting groove 9 in the forming mold, and the gutter supporting body B is formed of the synthetic resin, which is therefore introduced into the supporting hole 3 of the holding plate 2. In this case, the fixing body A and the gutter supporting body B are formed in a separated body, not one body, because of temperature difference between them. Thus the fixing body A can be assembled simultaneously with the forming of the gutter supporting body.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a method for manufacturing a synthetic resin eave gutter support, which eliminates assembly steps and is movable by molding. It relates to the manufacturing method.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, eave gutter supports that are composed of a fixed body and a gutter support have been known. Conventionally, this eaves gutter support has been manufactured separately, and later assembled by rotatably assembling the fixed body and the gutter support.

[Problem to be solved by the invention]

Conventional methods for manufacturing eave gutter supports made of synthetic resin have the problem of requiring assembly man-hours.

In the present invention, when the fixed body is pre-molded and the gutter support is molded, the fixed body is set in the mold, and the fixed body is assembled at the same time as the gutter support is molded. The purpose is to provide a manufacturing method for manufacturing.

[Means to solve the problem]

In order to achieve the above object, the present invention comprises a fixed body in a specific shape, sets it in a mold when molding the gutter support, and simultaneously molds the gutter support with synthetic resin. The company manufactures eave gutter supports.

That is, a plurality of locking protrusions are formed on the upper surface, a holding plate is formed that protrudes upward, and a support hole is formed in the holding plate to form a fixed body, while a circular hole is formed on the bottom surface at the base end of the gutter support. A gutter support is formed by forming an engaging convex portion disposed in an arc shape and a fitting groove into which a retaining plate of the fixed body is fitted, and after integrally molding the fixed body with a synthetic resin. The fixing body is set in the mold for the gutter support, and then the gutter support is molded with synthetic resin, and the support hole of the retaining plate of the fixing body is made conductive with the synthetic resin of the gutter support, and the retaining plate is inserted into the gutter. It is an object of the present invention to provide a method for manufacturing a synthetic resin eaves gutter support tool that is fitted into a fitting groove of a support body and engages an engagement projection and a locking projection.

〔Example] Examples will be described with reference to the drawings.

FIG. 1 shows a fixed body A, in which 1 is a locking convex portion, 2 is a holding plate, 3 is a support hole, 4 is a fixed body, and 5 is a fixing hole. A plurality of locking protrusions l are formed and arranged in a sawtooth shape and a concave arc shape. The retaining plate 2 projects upward and is connected to the gutter support 8. This fixed body A is molded from a thermoplastic synthetic resin such as vinyl chloride resin or polyethylene resin.

FIG. 2 shows the gutter support B. The gutter support body B is formed by forming an engagement convex portion 8 on the lower surface of the base end 7 and a fitting groove 9 at the base end 7 of the gutter support portion 6 . The engagement convex portion 8 is arranged in an arc shape on the base end surface of the gutter support portion 6 . The gutter support part 6 is a part that supports the gutter, and is not limited to a specific structure.

First, the fixed body A is integrally molded from a synthetic resin, and then the molded fixed body A is set in a mold for the gutter support B. 3 and 4 show a synthetic resin eaves gutter support consisting of a fixing body A and a gutter support B. That is, after the fixed body A is set in a mold, the gutter support body B is molded. In this case, the holding plate 2 of the fixed body A is fitted into the fitting groove 9 of the gutter support body B, and the locking protrusion 1 is engaged with the engagement protrusion 8. When molded in this state, the synthetic resin used to mold the gutter support body B is electrically connected to the support hole 3 of the holding plate 2. In this case, it may be thought that the fixed body A and the gutter support B are integrated, but the fixed body A is a molded product that has already been cooled, and the gutter support B
Even when the molten resin used to mold the fixed body A comes into contact with the fixed body A, there is a temperature difference, and the molded body is not an integral molded product, but is a separate body. For this purpose, when an external force is applied to the gutter support B, the gutter support A rotates. In this case, the locking protrusion 1 and the engagement protrusion 8 engage with each other, resulting in a large resistance, but since it is made of synthetic resin, it rotates due to its elasticity. This rotation allows the position of the gutter support section 6 to be adjusted. The resin for molding the gutter support body B may be the same as the resin for molding the fixed body A.

〔Effect of the invention〕

As explained above, in the present invention, the entire device is made of synthetic resin, so there is no risk of rusting, and manufacturing does not require assembling man-hours.
