Problems solved by technology

[0010] Therefore, in the existing structure, when an external force acts on the visor and the stress concentrates at the junction of the visor and the cap body and there is a tendency to deform, there is a problem that the visor is easy to break away from the cap body. The metal model for the visor needs to form structures such as locking parts and locking holes, so there is a problem that the structure of the metal model becomes complicated.

Abstract

A helmet (1) with a visor formed by integrally joining the preliminarily injection-molded visor (5) to a cap body (3), wherein an opening end edge part (9) formed on the cap body is joined to the outer side of a joining wall part (17) formed on the visor (5), and the joining wall part (17) is held by the opening end edge part (9) and a tongue-shaped part (31) formed on the inside of the cap body (3). The joined faces of the visor (5) and the cap body (3) are joined to each other by fusing, an intruding engagement part intruded in a through hole (22) formed in the joining wall part (17) is formed at the opening end edge part of the cap body (3), and the joined parts of the visor and the cap body are formed in annular shapes.

Description

technical field [0001] The present invention relates to a helmet with a visor, and more particularly to a thin sheet resin molded product that is pre-injection-molded with a visor and the cap body of the resin injection molded product of the helmet in the injection molding of the cap body. A helmet with a brim that joins together when molded. Background technique [0002] Among the helmets with visors used as safety helmets such as construction sites and civil engineering construction sites, helmets with visors with transparent visors have been proposed in order to expand the upper line of sight (for example, refer to Patent Document 1: Japanese Patent No. 298469). [0003] As shown in FIG. 11 , the helmet with visor 100 disclosed in the above-mentioned Patent Document 1 is a transparent visor 102 integrally joined to the lower front side of a cap body 101 . In order to improve the strength of the joint portion between the cap body 101 and the visor 102, while a plurality o...
