Hard hat trim fixing method

The invention relates to a method for fixing a safety helmet trim, and relates to a production, processing and processing procedure of a safety helmet.

In order to prevent the brim of the safety helmet from cutting people and increase the appearance, rubber or leather side strips are generally fixed on the brim of the helmet;

In the past, most of the edge strips were fixed to the brim of the hat by machine sewing, but this method is only suitable for half-shield or three-quarter-shield helmets. The opening of the face of the full-face helmet cannot be inserted by the machine due to the small space. to do the work.

In view of the above shortcomings, the inventor believes that it is necessary to correct it. Based on his many years of experience in related technologies and product design and manufacturing, and adhering to the excellent design concept, he researched and created the above shortcomings. After continuous efforts, he finally achieved Introduce the fixing method of helmet trim of the present invention, hoping to correct the product structure and improve the excellent efficacy of the product.

The main purpose of the method for fixing the trim of the helmet of the present invention is to provide a process method for applying the trim to the face opening of the full-face helmet.

In order to achieve the purpose of uncovering, the safety helmet trim fixing method of the present invention includes:

1.Providing a set of strips, providing a set of strips, the strip has a U-shaped cross-section, and one of the outer sides of the strip protrudes to form a positioning part;

1.Procedure for providing the exterior decoration layer, providing an exterior decoration layer, one side of the exterior decoration layer is pasted with a double-sided adhesive tape;

A pre-positioning process, using the double-sided adhesive to stick the exterior layer on the outside of the strip body where the positioning part is located, and make one side of the exterior layer abut against the positioning part;

A sewing process, the outer decoration layer is sewn to the outside of the strip body where the positioning part is located, and a seam is generated on the inside of the strip body;

A double-sided tape sticking process, sticking another double-sided tape on the exterior layer;

An isolation process, applying a layer of glue to the seam to cover the seam;

A set of strip fixing procedures, the strip body is placed on the edge of a helmet shell, and the inner side of the strip body is fixed to the safety helmet shell by using glue, wherein the positioning part is located on the outside of the safety helmet shell;

A post-positioning process, the exterior layer is pasted and fixed on the inside of the helmet shell through the double-sided adhesive tape for pre-positioning, and wrinkles are reduced in order to allow the exterior layer to conform to the curvature of the helmet shell , the exterior layer and the double-sided adhesive can be cut out at the bend corresponding to the edge of the safety helmet shell;

A fixing procedure of the outer decoration layer, tearing off the double-sided adhesive sticking part of the outer decoration layer, and then fixing the outer decoration layer on the inner side of the helmet shell with glue.

After carrying out the above steps, trims can be made on the edge of the helmet shell, especially the face opening of the full-face helmet that the machine cannot penetrate, and then solve this long-standing problem. It is obvious that the present invention is a Progressive creation.

[Please refer to the first figure to the tenth figure] The present invention relates to a method for fixing the trim of a safety helmet, which includes the following steps:

A procedure for providing a set of strips (S1), providing a set of strips (1), the set of strips (1) having a strip body (11) with a U-shaped cross section, one of the outer sides of the strip body (11) protruding A positioning part (12) is formed, and the sleeve (1) can be made of but not limited to rubber, plastic or silicon rubber;

1. Provide an outer decoration layer procedure (S2), provide an outer decoration layer (2), one side of the outer decoration layer (2) is pasted with a double-sided adhesive tape (21), the outer decoration layer (2) can be but not limited to cloth , leather or artificial leather material;

A pre-positioning procedure (S3), using the double-sided adhesive (21) to stick the outer decoration layer (2) on the outer side of the strip body (11) where the positioning part (12) is located, and make the outer decoration layer (2) ) one side abuts against the positioning part (12) for pre-positioning;

A sewing procedure (S4), sewing the exterior layer (2) to the outside of the strip body (11) where the positioning part (12) is located, and creating a seam on the inside of the strip body (11) (13);

A double-sided adhesive sticking process (S5), pasting another double-sided adhesive (21) on the exterior layer (2);

An isolation process (S6), applying an adhesive layer (3) on the seam (13) to cover the seam (13), the adhesive layer (3) can be but not limited to super glue;

A strip fixing procedure (S7), the strip body (11) is placed on the edge of a helmet shell (4), and the inner side of the strip body (11) is fixed to the helmet shell ( 4), wherein the positioning part (12) is located outside the helmet shell (4);

A post-positioning procedure (S8), the outer decoration layer (2) is pasted and fixed on the inner side of the safety helmet shell (4) through the double-sided adhesive tape (21) for pre-positioning, and in order to make the outer decoration layer (2) To conform to the curvature of the helmet shell (4) and reduce wrinkles, the outer decoration layer (2) and the double-sided adhesive tape (21) can be cut out at the curved part corresponding to the edge of the helmet shell (4). gap (22), and the outer decoration layer (2) can be pasted along the curvature of the helmet shell (4);

An outer decoration layer fixing procedure (S9), tearing off the double-sided adhesive tape (21) of the outer decoration layer (2) one by one along the length direction of the outer decoration layer (2), and using the glue The outer decoration layer (2) is glued to the inner side of the safety helmet shell (4) until the whole outer decoration layer (2) is glued to complete.

[Please refer to the first picture to the tenth picture] The strip (1) can be made into different sizes to match different helmets, and in the pre-positioning process (S3), one side of the outer layer (2) is attached to the positioning part ( The purpose of 12) is not only for the pre-positioning of the subsequent sewing, the positioning part (12) can also block the edge burrs of the outer decoration layer (2) to make it more beautiful. ) The purpose of applying the adhesive layer (3) is that the adhesive layer (3) can prevent the glue from seeping out from the seam (13) during the strip fixing procedure (S7) and affect the operation, while the strip fixing procedure (S7) It can be carried out when the glue layer (3) is not solidified or solidified;

The glue used in the strip fixing procedure (S7) and the exterior layer fixing procedure (S9) can be quick-drying, and is glued along the length direction of the strip body (11) in the strip fixing procedure (S7). The strip body (11) contacts the inner side of the outer side of the cap shell (4) as shown in the fifth figure;

The purpose of pre-positioning the outer decoration layer (2) through the double-sided adhesive tape (21) as shown in the seventh, eighth, and ninth pictures is to facilitate the operator to adjust the position where it can be pasted neatly, and to determine the gap (22) ) cutting position and cutting size, to avoid the problem of easy mistakes and rework when directly using glue to fix;

In addition, although the tenth figure is applied to a three-quarter helmet as an example, the main purpose of the present invention is to apply it to the face opening edge of a full-face helmet, so as to solve the problem that conventional sewing machines cannot penetrate into the face opening. Problems doing homework.

What is described above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. That is to say, all equivalent changes and modifications made according to the scope of the patent application should still fall within the scope covered by this creation patent.

To sum up, if the invention is novel and progressive, and the invention has not been published in any publication, it shall comply with the provisions of Article 22 of the Patent Law.
