In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a perspective view of a forced fastening helmet according to an embodiment of the present invention, FIG. 2 is a view showing an internal structure of a forced fastening helmet according to an embodiment of the present invention, and FIG. 3 is a cross- FIG. 4 is a view showing a balance part of a forced fastening helmet according to an embodiment of the present invention. FIG.

The forced fastening helmet according to one embodiment of the present invention includes a parent body 100, a buffer material 200, an inner skin, and a balance part 300.

The mother body 100 is made of a hard material so as to protect the head from an external impact caused by a fall or the like, and has a substantially hemispherical shape. The cushioning material 200 is coupled to the inner side of the matrix 100 so as to absorb the impact transmitted from the matrix 100.

The endothelium is wrapped around the crown and head circumference, and is coupled to the inside of the matrix 100 so that the matrix 100 can be worn on the head. (Not shown) provided around the inner periphery of the mother body 100 and in close contact with the wearer's head, and an overhead band (not shown) fixed to the head band and wrapping the top of the wearer's head. .

The balance unit 300 includes a guide body 310 formed along the inner surface of the matrix 100 and a weight 320 slidable along the guide body 310. The guide body 310 includes a guide plate 311 having a plate shape bent along the matrix 100 and a guide wall 312 extending vertically from both corners of the guide plate 311 toward the matrix 100 . A fixed chin strap 331 is fixedly coupled to one end of the guide body 310 and a slit shape is formed in the guide wall 312 facing each other from the center of the guide wall 312 toward the fixed chin strap 331 side And a sliding guide hole 313 extending and penetrating is formed.

The weight 320 is preferably made of a material having a high specific gravity, and may be a metal such as lead as an example. On both sides of the weight 320, a sliding guide hole 321 is formed at a predetermined height and the sliding guide hole 321 is inserted into a corresponding sliding guide hole 313. Therefore, the weight guide 320 can slide along the guide body 310 because the sliding guide hole coupling part 321 can move along the sliding guide hole 313.

A sliding chin strap 330 is coupled to one side of the weight 320 and extends along the inner side of the guide body 310 toward the opposite side of the fixed chin strap 331 of the guide body 310. At this time, the end of the sliding chin strap 330 extends to protrude outward from the guide body 310.

The locking portions 340 are coupled to the end portions of the fixed chin strap 331 and the sliding chin strap 330 so that the locking portions 340 are detachable from each other. Therefore, by fastening the lock portion 340, the chin strap is held close to the wearer's chin so that the mother body 100 is fixed so as not to come off the wearer's head.

FIGS. 5A and 5B are diagrams illustrating weight movement of a forced fastening helmet according to an embodiment of the present invention. Referring to FIG. 5A, the weight 320 is slidingly moved along the guide body 310 by gravity and descends. The descending of the weight 320 is performed by gravity and the sliding chock strap 330 coupled to the weight 320 is pulled by the weight 320 and inserted into the guide body 310. At this time, the sliding chin strap 330 is not completely inserted into the guide body 310, and a portion including the lock portion 340 is exposed to the outside of the guide body 310.

Referring to FIG. 5B, the fastening state of the locking part 340, that is, the state where the wearer fixes the chin strap is shown. When the wearer pulls the sliding chin strap 330, the weight 320 moves along the guide body 310 and is located at the upper center portion. When the lock 340 is fastened, the weight 320 moves the balance chin 300 And is fixed at the upper center portion to complete the hair-knitting.

FIG. 6 is a view showing a state in which a forceps tightening helmet according to an embodiment of the present invention is worn when the chin strap is not attached. Referring to FIGS. 5A and 6, when the chin strap is not locked, the weight 320 descends to one side, and the center of gravity of the helmet is moved to one side. Therefore, the helmet is worn in a state of being tilted at the head of the wearer, so that normal wearing is impossible. That is, when the chin strap is not fastened, it can not be worn. However, referring to FIG. 5B, when the chin strap is tightened, the weight 320 is positioned at the center of the helmet, and the helmet is balanced right and left, so that the helmet can be normally worn.

According to another embodiment of the present invention, a portion of the cushion material 200 is removed, and the height at which the guide body 310 is directly coupled to the matrix 100 and protruded from the matrix 100 can be reduced. Accordingly, a space between the wearer's head and the balance part 300 can be formed with a sufficient space.

According to another embodiment of the present invention, the weight guide 320 can be slidably moved inside the guide body 310 without forming the sliding guide hole 313 and the sliding guide hole 321.

According to still another embodiment of the present invention, the locking part 340 is not constituted, and the fixed chin strap and the sliding chin strap are always connected by the chin strap length adjusting means, so that, in a state in which the length of the chin strap is adjusted to fit the wearer, Can be pulled to wear a safety helmet. In other words, the helmet can be worn without locking the chin strap. Here, the means for adjusting the length of the chin strap is merely a well-known conventional technique, so that further explanation will be omitted.

According to another embodiment of the present invention, the sliding chin strap fastening means can be configured. In a state in which the chin strap is fastened, the sliding chin strap fastener 330 can be fixed to the safety hat using the sliding chin strap fastening means. When the weight 320 is heavy, a tension may be applied to the sliding chin 330 according to the degree of tilting of the helmet in a state wearing the helmet, which may be uncomfortable because pressure is applied to the jaw of the wearer. However, if the sliding chin strap 330 is fixed so as not to be slidably movable, the pressure is not applied and the inconvenience at the time of wearing can be completely prevented. The sliding chin strap fastening means may be a buckle or a fixing clip, but is not limited thereto, and any means capable of fixing the sliding chin strap 330 is possible.

On the other hand, the balance unit 300 and the like can be applied not only to helmets but also to helmets, general hats, and the like, all worn on the head.

When a safety helmet is worn without fixing the chin strap at a factory or a construction site, the safety helmet may peel off during a safety accident, resulting in a head injury. In particular, the helmet is easily peeled off when a worker falls. Therefore, there is a problem that the work process is disrupted due to the loss of life and the rise of the injury, as well as the social loss increases. In order to prevent this, the supervisor supervises the chuck strap to be fixed when the helmet is worn, and the safety education is also strengthened. However, because of the inconvenience or inconvenience, it is often worn without fixing the chin strap of the helmet, and it is impossible to systematically manage all personnel, and many workers are exposed to the risk of accidents.

However, according to the present invention, the safety helmet can be normally worn only when the chin strap is worn and fixed, so that the safety helmet can be prevented from easily peeling off.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various modifications and variations are possible within the scope of the appended claims.
