Description

SWEAT ABSORBING PAD FOR SAFETY HELMET AND MANUFACTURINGMETHOD THEREOF

Technical Field

The present invention relates to a sweat absorbing pad for a safety helmet, which is detachably attached to a head fitting band arranged inside the safety helmet in such a way as not only to absorb sweat flowing to the brow of a wearer but also to perform finger- pressure treatment for the head, thereby ensuring hygiene and improving workability of the wearer, and is marked on an inner surface thereof with a safety notice in such a way as to stir up attention of the wearer in safety, and a manufacturing method thereof.

Background Art

Generally, a safety helmet includes a helmet body, a supporting basket, a shock absorbing member, a chin strap and a visor. The helmet body covers the head of a wearer. The supporting basket alleviates shock which is transmitted to the head of the wearer when impact is exerted on the safety helmet, and is composed of diametrically extending head supporting bands, a circumferentially extending head fitting band and a head supporting ring. The shock absorbing member is attached to an inner surface of the helmet body to further alleviate the shock which is transmitted to the head of the wearer. The chin strap prevents the helmet body from being released from the head of the wearer. The visor is integrally formed with the helmet body and is defined with a ventilating hole. The visor performs a shading function. If the wearer works while wearing the safety helmet constructed as mentioned above, sweat comes out due to heat generated in the head upon working. After the sweat passes through the head fitting band of the supporting basket, the sweat flows downward to the face via the brow of the wearer.

At this time, due to the fact that the head fitting band which is closely brought into contact with the brow of the wearer, is simply fitted around the head to prevent the safety helmet from being released from the head of the wearer, the head fitting band does not have a sweat absorbing function.

As a consequence, a worker, that is, the wearer must separately prepare a towel to wipe the sweat flowing downward upon working. Otherwise, the worker must cover the head with a towel before wearing the safety helmet so that the towel is intervened between the head and the head fitting band of the supporting basket after wearing the safety helmet and thereby sweat is absorbed into the towel.

However, in the former case that the towel is additionally used to wipe the sweat, inconvenience is induced to the wearer of the safety helmet, and in the latter case that the towel is laid on the head before wearing the safety helmet, since the head fitting band cannot be stably fitted around the head of the wearer, uncomfortableness is caused upon wearing the safety helmet and, at the worst, the safety helmet can be released from the head.

Disclosure of the Invention Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a sweat absorbing pad for a safety helmet, which is detachably attached to a head fitting band arranged inside the safety helmet, in such a way as to absorb sweat flowing to the brow of a wearer, and a manufacturing method thereof.

Another object of the present invention is to provide a sweat absorbing pad for a safety helmet, in which projections are formed at both ends of the sweat absorbing pad in such a way as to perform finger- pressure treatment for the head of a worker, thereby allowing fatigue of the worker to be easily relieved, and a manufacturing method thereof.

Still another object of the present invention is to provide a sweat absorbing pad for a safety helmet, which is marked on an inner surface thereof exposed to an inside space of the safety helmet with a safety notice, in such a way as to stir up attention of the wearer in safety, and a manufacturing method thereof.

In order to achieve the above objects, according to one aspect of the present invention, there is provided a safety helmet comprising: a sweat absorbing pad detachably attached, by attaching and detaching means, to an inner surface of a head fitting band which constitutes a supporting basket of the safety helmet and which is to be directly brought into contact with the brow of a wearer, with the inner surface exposed to an inside space of the safety helmet, in a manner such that the sweat absorbing pad can absorb sweat flowing to the brow of the wearer. According to another aspect of the present invention, the sweat absorbing pad comprises at least two pad parts which are stacked one up the other.

According to another aspect of the present invention, an intermediate pad part for absorbing sweat, which has a predetermined narrow width, is inserted between the at least two pad parts which are stacked one up the other, in a lengthwise direction of the at least two pad parts.

According to another aspect of the present invention, finger- pressure treatment performing projections are formed at both ends of the sweat absorbing pad. According to another aspect of the present invention, a plurality of embossments are formed on an inner surface of the sweat absorbing pad which inner surface is exposed to the inside space of the safety helmet, and the sweat absorbing pad is marked on the inner surface thereof with a safety notice for stirring up safely attention of the wearer.

Best Mode for Carrying Out the Invention Reference will now be made in greater detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.

The present invention includes, as its essential component elements, a safety helmet 10, a sweat absorbing pad 20 arranged inside the safety helmet 10 to absorb sweat flowing to the brow of a worker, that is, a wearer, and attaching and detaching means 30 for detachably attaching the sweat absorbing pad 20 with respect to the safety helmet 10.

The safety helmet 10 has the same configuration as the conventional safety helmet. That is to say, the safety helmet 10 includes a helmet body 11, a supporting basket 15, a shock absorbing member 16, a chin strap and a visor 17. The helmet body 11 covers the head of the wearer. The supporting basket 15 alleviates shock which is transmitted to the head of the wearer when impact is exerted on the safety helmet 10, and is composed of diametrically extending head supporting bands 12, a circumferentially extending head fitting band 13 and a head supporting ring 14. The shock absorbing member 16 is attached to an inner surface of the helmet body 11 to further alleviate the shock which is transmitted to the head of the wearer. The chin strap prevents the helmet body 11 from being released from the head of the wearer. The visor 17 is integrally formed with the helmet body 11 and is defined with a ventilating hole. The visor 17 performs a shading function.

A portion of the heat fitting band 13 which portion is to be brought into contact with the brow of the wearer, is fixedly surrounded by a brow-contacting fabric band 18 which is defined with a plurality of air venting pores. The sweat absorbing pad 20 is attached to an inner surface of the brow-contacting fabric band 18 which inner surface is exposed to an inside space of the safety helmet 10, by the attaching and detaching means 30. The sweat absorbing pad 20 is made of natural pulp and has a size which allows the sweat absorbing pad 20 to be closely brought into contact with the brow of the wearer along a substantially arcuate path.

In other words, the sweat absorbing pad 20 comprises at least two pad parts which are stacked one up the other so that sweat absorbing force thereof can be enhanced. In this preferred embodiment of the present invention, the sweat absorbing pad 20 comprises three, that is, first through third pad parts 21, 22 and 23.

In this connection, the third pad part 23 has a lengthwise size which is the same as the first and second pad parts 21 and 22, and a width which corresponds to a half of each width of the first and second pad parts 21 and 22. Both surfaces of the third pad part 23 are coated with adhesive layers 24 to be adhesively bonded to the first and second pad parts 21 and 22, respectively.

Due to this, in case that sweat flows to the brow while the worker wears the safety helmet 10, a greater amount of sweat can be absorbed in a lower region than an upper region of the sweat absorbing pad 20, and it is possible to provide cushioning force to the wearer.

The attaching and detaching means 30 comprises an adhesive tape 31 which is attached to an outer surface of the sweat absorbing pad 20 constituted by a stacked combination of the first through third pad parts 21, 22 and 23, that is, an outer surface of the third pad part 23. As in the conventional adhesive tape, the adhesive tape 31 is composed of an adhesive layer and a backing paper which is removably attached to the adhesive layer.

A sweat absorption preventing film 50 is intervened between the third pad part 23 and the adhesive tape 31, and an adhesive layer 24 is coated on an outer surface of the sweat absorption preventing film 50.

The sweat absorption preventing film 50 is made of polyethylene resin in a manner such that the sweat absorption preventing film 50 can allow air to pass therethrough and prevent water leakage therethrough. Due to this, even though sweat which comes out from the head of the wearer, is absorbed into the sweat absorbing pad 20, sweat cannot leak into the adhesive layer 24 which is sandwiched between the brow- contacting fabric band 18 and the sweat absorption preventing film 50.

Here, in place of the adhesive tape 31, the attaching and detaching means 30 can comprise a Velcro-brand hook and loop fastener strip. Further, a cover 25 which is made of all-cotton material, is attached to an inner surface of the first pad part 21 which inner surface is exposed to the inside space of the safety helmet 10. The cover 25 is formed with a safety notice marking portion 26 for stirring up safety attention of the worker. Finger-pressure treatment performing projections 40 are inwardly formed at both ends of the sweat absorbing pad 20.

By the fact that the sweat absorbing pad 20 and the cover 25 are formed with a plurality of integral cushioning embossments, wearing comfortableness is rendered to the wearer of the safety helmet 10.

Each of the finger-pressure treatment performing projections 40 is made of resinous material, elvan, precious stone, magnetic material, and so forth. Each finger-pressure treatment performing projection 40 may be formed to have a predetermined size and of soft material so that the finger-pressure treatment performing projections 40 do not press the head with excessive force while the wearer wears the safety helmet 10.

As described above, the cover 25 is attached to the inner surface of the sweat absorbing pad 20 which inner surface is to be brought into contact with the brow of the wearer, and the cover 25 is formed with the safety notice marking portion 26 for stirring up safety attention of the worker. Also, it is preferred that the cover 25 be made of all-cotton material to render pleasant wearing feeling to the worker of the safety helmet 10. On the safety notice marking portion 26, there is marked a safety notice which is suitable for accomplishing advertising effect, depending upon use of the safety helmet 10.

Hereinafter, a method for manufacturing the sweat absorbing pad for a safety helmet, constructed as mentioned above, will be described in detail with reference to FIG. 4. First, in a pad parts cutting step SI, the pad parts 21, 22 and 23 are cut from pulp material so that each of the pad parts 21, 22 and 23 has predetermined area and length to be capable of being brought into close contact with the inner surface of the head fitting band 13 which constitutes the supporting basket 15 of the safety helmet 10. Then, the first and second pad parts 21 and 22 which are cut in the cutting step SI, are stacked one up the other, and the third, that is, intermediate pad part 23 of the predetermined narrow width is interposed between the first and second pad parts 21 and 22 using adhesive (step S2). Thereafter, the sweat absorption preventing film 50 is bonded to a surface of a resultant pad part combination, the adhesive layer 24 is coated on the sweat absorption preventing film 50, and the backing paper is attached to the adhesive layer 24 (step S3). Thereupon, the cover 25 which is marked with the safety notice for stirring up safety attention of the wearer, is attached to a surface of a resultant structure (step S4). In these ways, manufacturing of the sweat absorbing pad 20 for the safety helmet 10 is completed. The sweat absorbing pad 20 which is manufactured in these ways, can be used in a manner such that, after removing the backing paper which constitutes the adhesive tape 31, the sweat absorbing pad 20 is attached to the inner surface of the brow-contacting fabric band 18 which surrounds the portion of the head fitting band 13 of the safety helmet 10.

Then, as the worker wears the safety helmet 10, safety attention of the worker can be stirred up by the safety notice which is marked on the safety notice marking portion 26 of the cover 25. At the same time, while the worker wears the safety helmet 10, sweat which flows to the brow of the worker, can be absorbed by the sweat absorbing pad 20, and wearing comfortableness is improved by the presence of the plurality of embossments. Moreover, since the finger-pressure treatment performing projections 40 press the vein of the worker, fatigue of the worker can be easily relieved.

Industrial Applicability As a result, the sweat absorbing pad for a safety helmet according to the present invention provides advantages in that, since the sweat absorbing pad made of pulp material is detachably attached to a head fitting band which is arranged inside the safety helmet and in which the head of a wearer is to be fitted, smooth wearing feeling can be rendered to the wearer of the safety helmet, sweat flowing to the brow of the wearer can be rapidly absorbed by the sweat absorbing pad, and the sweat absorbing pad can be changed with new one in a simple manner to allow the wearer to feel fresh wearing feeling.

Also, because projections are formed at both ends of the sweat absorbing pad in such a way as to perform finger-pressure treatment for the head of a worker, fatigue of the worker can be easily relieved upon wearing the safety helmet.

Further, by the fact that the sweat absorbing pad which is attached to the head fitting band of the safety helmet, is marked on an inner surface thereof exposed to an inside space of the safety helmet with a safety notice, safety attention of the wearer can be effectively stirred up.
