Description

Headlamp integrated safety helmet

The present invention relates to a new concept technology for safely protecting electric wires while having a simple wiring structure for supplying power to the headlamp as well as being very convenient to use because a headlamp that can be charged in a helmet is integrally provided.

In general, a hard hat is a hat worn by field workers for the purpose of preventing safety accidents at industrial sites such as construction sites, shipyards, and mines, and consists of an inner skin that comes into contact with the wearer's head and a hard outer skin that surrounds them.

However, most of the conventional hard hats do not sufficiently meet the various needs of users other than the function of protecting the wearer's head from external impact.

In particular, when working in a dark field such as at night or in a tunnel where there is no light, since a lighting lamp and a flashing lamp are essential, it is cumbersome as well as inconvenient because it is necessary to separately carry the lighting lamp and the flashing lamp.

For this reason, in the prior art, a headlamp for lighting or a headlamp for flashing was separately purchased for a helmet, and the helmet was wrapped with a rubber band around the outer periphery and used.

However, as the rubber band is stretched due to repeated detachment, there is a problem of detachment from the hard hat, as well as a high cost problem because each must be purchased separately.

However, in the prior art, the wiring structure between the head lamp and the battery is not concise, and the wires are exposed and the wires are broken.

In addition, as the helmet is kept in a state of being worn only by the chin strap, the safety helmet is unexpectedly peeled off, and there is no function to protect the ear or cold weather at all, causing injuries or difficult to withstand the cold.

In addition, the wearer's head is only used for the purpose of protecting the wearer's head from external impact, and there is no function to protect the worker from various pests parasitic in the poor worksite, thereby causing a problem in that the utilization of the helmet is reduced.

As a means for solving the above problems, the present invention operates a headlamp installed through the front of the helmet with the power of a battery charged by itself using a charger provided inside the helmet to conveniently secure a field of view at the job site. In addition, a technology for simplifying the wiring structure by accommodating the various wires connected to the headlamp, the battery and the charger along the wiring path formed on the inner surface of the helmet is devised.

In addition, the present invention seeks a technique to protect the worker from pests in a poor worksite by operating the pest repellent provided inside the hard hat with the power of the battery.

In addition, the present invention seeks a technique for allowing the wearer's ear to be worn by hooking the ear wearers formed on both sides of the head holding band connected to the endothelium integrally installed inside the helmet.

According to the present invention, since the headlamp is provided integrally with the helmet, it provides a very convenient effect as well as secures the wearer's field of vision in a dark work site without the inconvenience of carrying a separate light or flashing light, respectively.

In addition, by accommodating various wires connected to the headlamp, the battery, and the charger along the wiring path formed on the inner surface of the helmet, the wiring structure is very simple, and the wire is safely protected to improve durability.

In addition, the present invention provides an effect of safely protecting the worker from pests in a poor worksite by operating the pest repellent with the power of the battery by having a pest repellent built-in in the repelling box formed on one side of the inner surface of the helmet.

In addition, by wearing the ear hooks formed on both sides of the head holding band on the worker's ear, it not only prevents the helmet from unexpectedly peeling off, but also protects the ear area and provides an effect of protecting from the cold.
