Description

The present invention relates to a helmet for protecting a head from an external impact and a method for manufacturing the helmet.

  In general, at construction sites, workers are required to wear a helmet to protect their heads.

  A helmet used in a work site or the like includes a cap-shaped helmet body for protecting the entire head, and a head holding member assembled to the inner surface of the helmet body. The helmet body is made of a plastic resin material, particularly a high-strength resin material such as ABS resin or fiber reinforced plastic (FRP).

  When a person wears such a helmet, the person's head is held by a belt-like head holding member, and the space formed between the person's head and the inner surface of the helmet body impacts the helmet body. When it is added, it plays a role of buffer so that the head does not hit the inner surface of the helmet body.

The working helmet is usually displayed on the surface of the helmet body with the company name, owner name, safety slogan, and the like. Such a display uses a label with an adhesive on the surface of the helmet main body, and displays or decorates the surface by means such as printing.
By the way, such a display method is poor in durability of the display, and the display is often deteriorated and becomes unreadable by long-term use.

Furthermore, the helmet body has a non-planar shape like a cap, and when displaying with such a label with an adhesive on the surface, the label does not wrinkle along the entire surface of the non-planar cap-shaped surface. It was difficult to stick. Further, even in the printing method, it has been extremely difficult to perform a display having an excellent appearance without causing distortion of figures and characters.
Accordingly, there has been a demand for a helmet that can display durable characters, images, and the like on the surface of the helmet body by simple means.

Recently, it has been recommended to wear a helmet to avoid dangers, such as when a child drives a bicycle. In order for children to wear their own helmets, it is preferable to form images, figures, coloring patterns, etc. that suit the children's preference on the helmet surface, and there is a need for easy and inexpensive means for forming images and the like. Yes.

Utility Model Registration No. 3096392

The present invention was made in order to improve the above-mentioned drawbacks of the prior art, and it is easy to form decorations such as letters, images, figures, and coloring patterns on the surface of a non-planar cap-shaped helmet, especially its entire surface. An object of the present invention is to realize a helmet and a manufacturing method thereof.

  The helmet according to the present invention is a helmet including a helmet body and a head holding member disposed therein, and the inner surface is decorated using at least one of a character, an image, a figure, and a coloring pattern. The cap-shaped film decorating body is attached to the outer surface of the helmet body and fixed by means such as screwing. The cap-shaped film decorative body is formed into a shape substantially the same as the surface of the helmet body, and when the cap-shaped film decorative body is placed on the helmet body, the cap-shaped film decorative body may be in a close contact shape without forming an extra space. desirable.

Moreover, the manufacturing method of the helmet of this invention gives decoration which consists of at least one of a character, an image, a figure, and a coloring pattern on one surface of a transparent plastic film, and the said character, image, figure, coloring pattern, etc. are inner surfaces. Then, it is formed into a cap shape by means such as vacuum forming. A hole is formed in the bottom side portion of the cap-shaped film decorative body at a position corresponding to the opening formed in the bottom side surface of the helmet body, and the hole is placed on the helmet body to decorate the helmet body and the cap-shaped film decoration. It is manufactured by fixing the body with fasteners such as bolts and nuts. When the cap-shaped film decorating body and the helmet main body are fixed with a fixture, it is preferable to fix the head holding member disposed inside the helmet at the same time.

According to the helmet of the present invention, the helmet surface can be provided with a durable and replaceable display by a simple method. In addition, according to the helmet manufacturing method, it is possible to decorate and display the helmet surface with excellent appearance and durability by a simple method.

It is sectional drawing of the helmet of this invention.

(helmet)
FIG. 1 shows an example of the helmet of the present invention.
The helmet shown in the figure is mainly suitable for use at a construction site, and is a cap-shaped helmet body 2 that covers the head, and a hammock 3 and a headband 4 that are attached to the inner surface of the helmet body 2. In the state where a person wears a helmet, the person's head is fitted into the head holding member 7, and a buffer space is provided between the person's head and the inner surface of the helmet body 2. 8 is formed so that the head does not hit the inner surface of the helmet body 2 when an impact is applied to the helmet body 2.

  A collar 9 may be formed integrally with the front portion of the helmet body 2. The helmet body 2 is formed using an ABS resin or an impact-resistant plastic such as FRP.

  The head holding member 7 is a combination of a flexible belt such as plastic and has a shape that can be fitted to the head. This head holding member is a combination of the helmet body 2 and bolts and nuts. It is detachably fixed using such a fixture 5.

  On the outer surface of the helmet body 2, a cap-shaped film decoration body 1 with decoration on the inner surface is placed, and formed on the respective edges of the helmet body 2 and the cap-shaped film decoration body 1. It is fixed with the fixture 5 through the opening.

  This cap-shaped film decorative body can be formed of a thermoplastic transparent film such as polycarbonate.

  It is preferable to cover the edges of the helmet body 2 and the cap-shaped film decorative body 1 with an edge covering member 6 made of a rubber-like material in order to prevent cuts. The edge covering member is a long rod-like member having a concave cross section, and is fitted to protect the end of the helmet body 2 and the end of the cap-shaped film decorative body 1 in the groove.

(Manufacturing method of helmet)
Moreover, the manufacturing method of the helmet of this invention first decorates one surface of a thermoplastic transparent plastic film, such as a character, an image, a figure, a color pattern. These decorations can be performed by a conventionally known method such as screen printing, offset printing, and bubble jet (registered trademark) printing. The ink used for printing is preferably a pigment ink. Characters, images, figures, coloring patterns, etc. can be printed in any shape, but when forming a film, the characters, images, figures, coloring patterns, etc. are distorted because they are transformed from a flat surface into a cap shape. become. In consideration of this distortion, a desired appearance display can be finally obtained by printing characters, images, figures, coloring patterns and the like.

  The transparent plastic film subjected to the decoration is formed into a cap shape by means such as vacuum forming so that the characters, images, figures, coloring patterns, etc. are on the inner surface. The cap shape means a hat shape that approximates a human head.

  In molding the cap-shaped film decorative body, any known method can be adopted as a method for molding the thermoplastic film, but it is particularly preferable to employ the vacuum forming method as described above. The vacuum forming method is to prepare a mold in the shape of a cap-shaped plastic film decorative body, place the plastic film on it, and heat the plastic film while placing the plastic film on the concave and surface of the mold The inside of the space formed by the above is depressurized using an exhaust means such as a vacuum pump. The plastic film is heated, softened, closely contacts the inner surface of the concave portion of the mold to form a cap shape, and a molded body is obtained by cooling this.

  A predetermined number of holes for fixing are formed on the bottom side of the cap-shaped film decorative body at positions corresponding to the openings formed in the bottom side surface of the helmet body by a conventional means.

The cap-shaped film decorative body is placed in close contact with a helmet body created by a well-known method, and the helmet body and the cap-shaped film decorative body are fixed by a fixture. When the cap-shaped film decorating body and the helmet main body are fixed with a fixture, it is preferable to fix the head holding member disposed inside the helmet at the same time.
As a fixing tool in the present embodiment, a combination of a bolt and a nut, or a protruding member having a rod-like protrusion and a receiving tool having a hole fitted to the protrusion can be used.

  It is preferable that the edges of the helmet body and the cap-shaped film decorative body are in contact with each other. When these end portions are sharply shaped, people come into contact and cause cuts. Therefore, these edge portions may be covered with an edge covering member 6 made of a rubber-like material. This is preferable for preventing cuts. The edge covering member is a long rod-like member having a concave cross section, and is adapted to fit and protect the end of the helmet body and the end of the cap-shaped film decorative body in the groove. This rubber-like edge covering member 6 may be fixed to the end of the helmet body and the end of the cap-shaped film decorative body with an adhesive or the like, but in order to make the cap-shaped film decorative body replaceable. Is preferably in a state where it can be easily peeled off.

(Replacement of decorative body)
The cap-shaped film decorative body fixed to the surface of the helmet body can be easily obtained by releasing the locking by the edge covering member covering these edges and the fixing member fixing them. It is possible to detach without destroying the shape. And it can be easily set as the helmet of a different display by using a new cap-shaped film decoration body instead of an old cap-shaped film decoration body.
