Description

  This invention includes protective equipment such as dust-proof goggles used in factories and construction sites, sports goggles used in motor sports and skiing, face shields for disaster prevention and heat resistance, dust-proof masks, etc. The present invention relates to a clip for protective equipment for keeping it from falling off a helmet.

  Protective equipment such as dust-proof goggles and disaster- and heat-resistant face shields used in factories and construction sites are detachably attached to a disaster prevention helmet that is usually worn by workers.

  Such protective equipment is usually removed from the disaster prevention helmet worn by the operator, and is used together with the disaster prevention helmet only when performing specific work such as painting work or welding work. And when using such a protector together with a disaster prevention helmet, it is attached to the disaster prevention helmet with a clip for the protector so that the protector does not come off from the disaster prevention helmet.

  By the way, the disaster prevention helmets worn by workers are usually called "MP type", but in order to increase the safety of the helmet, rubber or synthetic resin trim is attached to the lower periphery of the helmet. In order to improve the strength of the helmet and the helmet, a grooved helmet in which a lower peripheral end is folded to form a rib groove is also widely used.

  Conventionally, as a clip for protective equipment suitable for an MP-type helmet, for example, as shown in FIGS. 13 and 14, a plate-like base portion 11 and a longitudinal section U continuous with a bent angle at the base portion 11. The base portion 11 is provided with a locking mechanism 11a for a protector, and the engaging portion 12 is a plate that can be bent by a tightening screw 13 in a curved space 12a. There is one in which the spring 14 is provided so as to extend from the vicinity of the continuous portion of the base portion 11 and the engaging portion 12 (Patent Document 1).

  And as a clip for protective equipment suitable for a grooved helmet, for example, as shown in FIG. 15, the lower end of the plate-like base portion 21 is bent in the horizontal direction to form an overhang portion 22, and this overhang portion It is assumed that a holding portion 24 is formed as a curved portion 23 by bending substantially semicircularly from the edge of 22 to the inner surface side of the base portion 21 and attached along the outer periphery of a rib formed by folding the lower peripheral end of the helmet. There exists such a thing (patent document 2).

  Furthermore, as a clip for protective equipment suitable for a grooved helmet, for example, as shown in FIGS. 16 and 17, it has a substantially U-shaped cross section so as to sandwich a rib L formed on the lower peripheral end of the helmet H. A bent clamping part 31 is formed, and a bent part 32 that fits into a rib groove La formed by the inner wall 31a of the rib L and the outer wall Ha of the helmet H is formed at the inner end 31a of the clamping part 31, and further the helmet H The outer wall Ha of the helmet H is pressed at its tip, and there is an elastic plate formed with an engaging portion 33 that has a space S between the outer wall Ha of the helmet H (Patent Document 3).

  Hereinafter, the form for implementing the clip for protectors of the helmet of this invention is demonstrated in detail based on drawing.

  As shown in FIGS. 1 to 3, the clip for the helmet protector according to the present invention has an insertion space S in which the mounting band B of the protector P is inserted between the plate-shaped main body 1 and the outer wall of the helmet H. A holding part 2 is provided at the lower part of the plate-like main body 1 so as to hold the lower peripheral end of the helmet H. The abutting part is provided at the upper part of the plate-like main body 1 so as to come into contact with the outer wall of the helmet H. 3 is provided.

  The plate-like main body 1 is made of a hard resin plate or a metal plate excellent in creep resistance, fatigue resistance, rigidity, and chemical resistance, and a sandwiching portion 2 provided at the lower portion of the plate-like main body 1 and the plate. It is assumed that a soft resin is attached to the contact portion 3 provided on the upper portion of the main body 1. As such a hard resin plate, for example, a polyacetal plate having a thickness of about 3 mm can be used. As the metal plate, for example, a thin steel plate having a thickness of about 1 mm can be used. Since the plate-like body 1 is made of a hard resin plate rather than a metal plate, it becomes an electrical insulator, so that it is safe for construction work dealing with electricity, and has a fleshy texture. It is preferable because the feeling is improved. In addition, the soft resin can be an elastomer having high elasticity, heat deterioration resistance, weather resistance, low temperature characteristics, electrical insulation, chemical resistance, or a resin having rubber elasticity equivalent to that of an elastomer. It can be about 1 mm.

  The clamping part 2 is formed by bending the lower part of the plate-like main body 1 to have a substantially U-shaped longitudinal section and providing a space Sa for clamping the lower peripheral end of the helmet H, and is inserted above the space Sa. It is assumed that a mouth 2a is provided, and a raised portion 4 that is elastically deformed by contacting the lower peripheral end of the helmet H is provided in the space Sa, and the contacting portion 5 is opposed to the raised portion 4. Is provided. In addition, although it is preferable in terms of performance and design that the longitudinal section of the sandwiching portion 2 is substantially U-shaped, it is limited to a substantially U-shape as long as the lower peripheral end of the helmet H can be sandwiched. There is nothing.

  The abutting portion 3 bends the upper portion of the plate-like main body 1 to have a substantially inverted U-shaped longitudinal section, the outer surface of the tip is a contact surface 3a with the outer wall of the helmet H, and the inner surface of the tip is a protective device P such as goggles. This is the retaining surface 3b of the mounting band B. The abutment portion 3 has a soft resin attached only to the tip, but needless to say, a soft resin may be applied to the whole. The vertical cross section of the abutting portion 3 is also preferably approximately inverted U-shaped in terms of performance and design. However, as long as it can contact the outer wall of the helmet H, it is limited to an approximately inverted U-shape. It will never be done.

  The raised portion 4 is made of a soft resin having a space Sb inside. The raised portion 4 may be formed separately from the soft resin applied to the sandwiching portion 2 and the abutting portion 3, but it is preferable to form the raised portion 4 at a time because the manufacturing can be simplified. This soft resin is made of the same material as that applied to the sandwiching part 2 and the abutting part 3 and has a JIS type A durometer hardness of 25 to 90 degrees. By making the soft resin within this hardness range, the raised portion 4 comes into contact with the lower peripheral end of the helmet H and is easily elastically deformed, while maintaining the elastically deformed state, It is easy to hold the peripheral edge.

  The shape of the raised portion 4 is an arch shape, and both sides are opened to make the space Sb an open space. As this arch shape, as shown in FIGS. 1-3, it is set as a shape where a longitudinal section becomes a semicircle, or it is set as a shape where a longitudinal section becomes a trapezoid as shown in FIG. As shown in 4b, the vertical cross section may have various shapes such as a shape in which two semicircles are connected.

  When the shape of the raised portion 4 is such that the longitudinal section is a semicircle, as shown in FIG. 4c and FIG. 4d, a slit 4a that cuts the raised portion 4 in the horizontal direction is formed. Alternatively, as shown in FIG. 4e, an elastic core material 6 that is more elastic than the raised portion 4 can be embedded along a semicircular arch shape. When the slit 4a is formed in the raised portion 4, adjustment can be performed so that the elasticity of the raised portion 4 is weakened. When the elastic core material 6 is embedded in the raised portion 4, adjustment can be performed so that the elasticity of the raised portion 4 is increased in accordance with the elastic force of the elastic core material 6.

  Furthermore, although the shape of the raised portion 4 is not shown, it can be formed into a dome shape in which both sides of the arch shape are closed and the both sides are not opened.

  In addition, as shown in FIG. 4f, the shape of the raised portion 4 may be such that a plurality of rod-shaped protrusions are provided so that the overall contour shape becomes a dome shape.

  In the helmet protector clip according to the present invention, the holding portion 2 is provided with a communication hole 7 communicating with the space Sb of the raised portion 4. This communication hole 7 makes the open space what the space Sb was a closed space when the raised portion 4 is formed in a dome shape. Further, as will be described later, the communication hole 7 becomes a screw hole for the set screw 8 of the spring band Sp when the protective device P such as goggles is attached to the helmet H using the spring band Sp. When the set screw 8 of the spring band Sp is screwed into the communication hole 7, even if the set screw 8 is too long, the tip of the set screw 8 hits the inner wall of the space Sb of the raised portion 4, and the helmet H The helmet H is not damaged because it does not hit the lower peripheral edge directly.

  The helmet protector clip of the present invention configured as described above is obtained by picking the sandwiching portion 2 or the contact portion 3 with a finger and, as shown in FIG. 5, from the insertion opening 2a of the sandwiching portion 2 of the helmet H. If the lower peripheral end is inserted into the space Sa of the sandwiching portion 2, the raised portion 4 is elastically deformed and can be attached to the helmet H.

  That is, the clip for the protective device of the helmet according to the present invention is a fire-fighting type (with trim) even if the helmet H is an MP-type helmet if the lower peripheral end of the helmet H is inserted into the space Sa of the holding part 2. 6 or 8, the raised portion 4 is elastically deformed to come into contact with the outside of the lower peripheral end of the helmet H, as shown in FIGS. 2 abuts against the inside of the lower peripheral end of the helmet H, and the abutment 3 abuts against the outer wall of the helmet H, and the abutment surface with these helmets H is made of soft resin. Because it is, it can be easily attached without scratching the helmet H.

  Furthermore, the clip for the protective device of the helmet of the present invention is supported on the lower peripheral end and the outer wall of the helmet H at the three points of the contact part 3, the raised part 4 and the contact part 5, Since the contact area between the elastically deformed raised portion 4 and the outside of the lower peripheral end of the helmet H is increased and the frictional force is increased, a stable attachment state can be maintained.

  Therefore, the clip for protective equipment of the helmet of this invention can be used corresponding to various types of helmets having different thicknesses and cross-sectional shapes of the lower peripheral end of the helmet without performing troublesome operations.

  And in such a state, the protector P is mounted | worn with the helmet H to which the clip for protectors of this invention was attached as follows.

  When the protective device P is made of goggles, as shown in FIGS. 9 and 10, the mounting band B is mounted on the lower peripheral portion of the helmet H and is inserted into the insertion space S of the plate-shaped main body 1 to come into contact with the protective gear P. If the hook 3 is hooked on the hooking surface 3b of the portion 3 or simply inserted into the insertion space S of the plate-like main body 1, the vertical movement of the wearing band B is restricted, and the work while wearing the helmet H is restricted. Goggles never fall off.

  When the goggles are attached to the helmet H using the spring band Sp, as shown in FIGS. 11 and 12, a set screw 8 is inserted into a through hole (not shown) provided at the end of the spring band Sp. , And the set screw 8 is screwed into the communication hole 7 of the sandwiching portion 2 so that the goggles will not fall off during the work while wearing the helmet H.

  Further, when the holder P is a face shield, although not shown, the face shield mounting frame is inserted into the communication hole 7 of the holding portion 2 in the same manner as when the goggles are attached to the helmet H using the spring band Sp. If the set screw is screwed in, the face shield will not come off during work while wearing the helmet H.
