Abstract

PROBLEM TO BE SOLVED: To provide the subject protection cap capable of preventing or reducing danger through being temporarily worn outside a helmet at a worksite highly dangerous due to objects coming flying or falling. SOLUTION: This protection cap is so designed as to have an inner surface profile nearly compliant with the outside profile of the headgear 1a of a helmet 1 to be worn and be formed so as to cover the helmet 1 with a lightweight cushioning material such as of expanded polystyrene. This protection cap may bear a brim or visor corresponding to that of the headgear 1a.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet crown protector for protecting the outside of a helmet such as an industrial safety hat.

[0002]

2. Description of the Related Art In general, an industrial safety helmet worn at a work site such as a construction site or a factory protects a wearer's head from danger caused by flying or falling objects, or prevents or reduces the danger caused by falling. In particular,
It is required by JIS and the like that the cap (shell) should have sufficient penetration resistance and shock absorption.

[0003]

However, although the conventional helmet is required to ensure the safety as described above, it is unfortunate that the helmet has an unfortunate case such as a fatal accident due to a flying object, especially at a construction site. Has occurred, and countermeasures have been requested.

SUMMARY OF THE INVENTION The present invention has been made in order to respond to the above-mentioned conventional demands, and an object thereof is to provide a method for mounting the above-mentioned conventional helmet on a work site where there is a high risk of flying or falling objects. An object of the present invention is to provide a helmet crown protector that can be temporarily worn to prevent and reduce danger.

[0005]

The helmet crown protector of the present invention has an inner surface shape substantially similar to the outer shape of the cap of the helmet to be crowned, and is made of a lightweight cushioning material such as styrene foam. Characterized by being formed into a cap so as to cover the cap. Further, the helmet crown protector of the present invention may be formed with a flange or an eave corresponding to the flange or eave of the cap of the helmet to be crowned.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 (A), 1 is a helmet, and 2 is a helmet crown protector to be crowned on the helmet 1. The helmet 1 is shown in FIG.
As shown in the figure, a cap body 1a made of a hard material, a hammock 1b, a headband 1c, a string 1d, etc., and a wearing body for holding the cap body 1a on the head, and the cap body 1
a, a shock-absorbing liner 1e for mitigating an impact transmitted to the wearer's head when an impact is applied to a, a chin string 1f for preventing the cap 1a from falling off the head, and a lower end of the cap 1a 1 g of flange that protrudes integrally over the entire circumference,
It is composed of

A helmet equipped with the protective body of the present invention is
The helmet 1 is not limited to the helmet 1 of the above embodiment, and may be any conventionally known helmet. In particular, the cap body 1a may have any shape not only with or without ribs but also over the entire outer surface shape. Further, a helmet having a structure without the shock absorbing liner 1e, the flange 1g, etc.
A helmet structure having an eave instead of g may be used.

The helmet crown protector 2 is formed from a lightweight cushioning material such as styrene foam. The inner surface shape of the helmet crown protective body 2 is formed into a shape substantially following the outer shape of the cap body 1a of the helmet 1. However, even if the cap body 1a has relatively small irregularities or undulations such as ribs, it is not necessary to accurately follow the irregularities or undulations.

The thickness of the helmet crown protector 2 can be appropriately selected depending on the required shock absorbing performance and the type of cushioning material, but is preferably, for example, 25 to 35 mm. Further, the thickness is not necessarily required to be uniform over the whole, and may be changed according to the protection purpose, the strength performance of the helmet, etc., for example, by making the top of the head somewhat thicker. Furthermore, the surface shape may be devised for design reasons irrespective of the performance, and as a result, the thickness may change.

A flange 2a is integrally and continuously formed on the lower outer peripheral portion of the helmet crown protection body 2 of the above embodiment, but the helmet to be crowned has no flange or eaves. Regardless, the flange 2a can be omitted.

As shown in FIG. 2, a recess 2 having an appropriate shape and size is provided inside the helmet crown protector 2.
One or a plurality of b may be formed. The helmet crown protective body 2 provided with the concave portion 2b may be broken or damaged by a fallen object or the like, and the impact force exerted on the helmet 1 may be weakened.

FIG. 3 shows still another embodiment of the helmet crown protector of the present invention. On the outer surface of the helmet crown protector 2, a hard synthetic resin, such as polystyrene, is used. A protective sheet 2c molded and processed to a thickness of about 6 mm is integrally covered with the protective sheet 2c for the helmet.
To protect. As a method for covering the protective sheet 2c, it is preferable to integrally mold the helmet crown protective body 2 and the protective sheet 2c, but they may be integrated by an appropriate adhesive.

[0013]

As described above, the protective body for a helmet according to the present invention has an inner surface shape substantially similar to the outer surface shape of the cap body of the helmet to be crowned, so that the protective body and the helmet cap body absorb shock. The synergistic effect of the function effectively absorbs the impact force on the protective body. 2) Since the helmet crown protector of the present invention is made of a lightweight material such as styrofoam, the wearer does not feel any particular burden even if the helmet is crowned outside the helmet. 3) Since the protective sheet is integrally coated on the outer surface, it is not only glossy and good-looking, but also less likely to be stained or scratched, and is expected to have a waterproof effect, and a helmet crown made of styrene foam or the like. Even if the protective body is deteriorated, the protective body is missing or the strength is improved, so that damage due to a falling object at the time of impact is small, and printing or sticking of a company name or name can be performed.
