Description

TECHNICAL FIELD The present invention relates to a work safety helmet having a disaster prevention surface for covering the face for the purpose of preventing dust and dirt.

2. Description of the Related Art Helmets whose disaster prevention surface is removably attached to a work safety helmet are known. This is a structure that pulls out from the helmet when the disaster prevention surface is needed, and pushes it into the helmet when it is not needed.

Problems to be Solved by the Invention Although the work safety helmet having the above-mentioned configuration does not hinder the taking in and out of the disaster prevention surface, this is easy because the disaster prevention surface is attached to the helmet with a special structure. Can not be removed, if you want to replace the disaster prevention surface for some reason, you need to remove the entire interior from the helmet. This is a troublesome work, takes time, and there is a strong demand for something that can be attached to the disaster prevention surface more easily and quickly.

It is an object of the present invention to provide a work safety helmet that meets this demand, facilitates the putting in and out of the disaster prevention surface, facilitates its attachment, and removes the disaster prevention surface when unnecessary.

The work safety helmet according to the present invention has a lever rotatably and movably attached to the inside of the helmet through pins on both sides of the helmet used for attaching the interior to the helmet. A disaster prevention surface is detachably attached to the mounting plate pivotally attached to the lever by hooks, extends along the front inner surface or side surface of the helmet, and mounting pieces having guard portions at both ends are attached to the pins, and the disaster prevention surface is the helmet. When it is pushed into the inside of the helmet, the guard plate frictionally engages the mounting plate with the inner surface of the helmet to hold the disaster prevention surface in the helmet.

Action With this configuration, if you pull the disaster prevention surface by hand, the disaster prevention surface will be smoothly pulled out from its retracted position along the front inner surface of the helmet by the action of the lever, and if pushed by hand, it will be easily pushed into the helmet. To be The disaster prevention surface can be easily removed from the mounting plate by pulling out the disaster prevention surface fully and removing the hooks.

Examples Referring to the accompanying drawings, as is well known, the helmet 1 is mounted on the inside of the helmet so that the helmet does not directly hit the head when the head is worn, that is, the helmet can be lifted from the head. It has a plastic interior 2. The interior 2 is detachably attached to a pin 3 provided around the helmet by a known method. Of these pins, a pair of left and right pins 3a to which the chin strap 4 is also attached are fitted with a plastic mounting piece 5 extending along the inner front surface or side surface of the helmet. The attachment piece 5 has integral guard portions 6 extending upward at both ends thereof. The front side portion of the interior 2 is attached to the pin 3b provided on the mounting piece 5. On each inside of the helmet, a plastic lever 7 has a slot 8 at one end.
The lever 7 is attached to the pin rotatably and movably by fitting the elongated hole 8 into the pin 3a. An elongated mounting plate 9 is pivotally attached 10 to the other end of the lever 7, and the mounting plate 9 is integrally formed with a protrusion 11 at its rear edge. The disaster prevention surface 12 made of plastic is detachably attached to the mounting plate 9 at each upper part of each side by using the hooks 13, and the disaster prevention surface 12 is attached by the side edges of the disaster prevention surface 12 contacting the protrusions 11 of the mounting plate 9. The position is regulated on the mounting plate 9 so as not to sway back and forth around the hook.
The disaster prevention surface 12 is preferably colorless and transparent, but may be colored and transparent, and may have a size that covers the face or a half size up to the nose position. In the former case, as shown in the figure, it is desirable that the disaster prevention surface 12 be provided with a large number of small holes 14 at the portion facing the mouth to prevent fogging due to breath.

The safety helmet for work according to the present invention is mounted by using the chin strap 4 as usual, but when it is desired to protect the face from dust and dirt during work, the disaster prevention surface 12 is grasped by hand and pulled out. At this time, the lever 7 rotates while moving with respect to the pin 3a on the rear side through the elongated hole 8, and further, the lever 7 and the mounting plate 9 rotate relative to each other, so that the disaster prevention surface 12 is substantially formed. The helmet 1 moves smoothly along the inner surface of the front side. The downward movement of the disaster prevention surface 12 is restricted by the lower edge of the lever 7 hitting the pin 3a on the front side, so that the disaster prevention surface 12 does not fall further down while wearing. When the disaster prevention surface 12 is not required, push the disaster prevention surface 12 upward by hand, and the disaster prevention surface 12 is moved in the opposite direction by the lever 7 between the helmet 1 and the mounting piece 5 by the lever 7. It will be pushed inside. At this time, the mounting plate 9 and the pivot pin of the lever 7 frictionally engage with the inner surface of the helmet 1 and the guard portion 6 of the mounting piece 5, whereby the disaster prevention surface 12 is unintentionally ejected from the retracted position. Never come. Further, since the guard portion 6 covers the lever and the mounting plate, the hair does not get caught on these components during the operation of storing or pulling out the disaster prevention surface.

When you want to replace the disaster prevention surface 12, first pull out the disaster prevention surface 12 fully to bring it closer to the hook 13, remove the hook to remove the disaster prevention surface from the mounting plate, and then remove the disaster prevention surface to be newly used. Attach to the mounting plate with a hook.

According to the present invention, according to the present invention, the lever is rotatably and movably mounted on the helmet, and the disaster prevention surface is detachably attached to the mounting plate pivotally attached to the lever by the hook. Needless to say, it is possible to easily and easily replace the disaster prevention surface without separating and removing the interior or the like.
