Description

  The present invention relates to an industrial safety cap, and more particularly to a safety cap that protects a human head in the event of a fall or fall.

  The industrial safety cap defined by Japanese Industrial Standard T811: 2000 includes a hard cap body and a wearing body made of a hammock, a headband, an annulus string, etc. that contacts the human head. Further, in this type of safety cap, an impact absorbing liner is attached to the inner surface of the cap body as a protective pad provided in addition to the wearing body in order to absorb the kinetic energy of the impact from the cap body.

  The shock absorbing liner is generally formed of foamed polystyrene or the like and covers most of the inner surface of the cap body. As a result, even if the wearer falls or falls, the shock absorbing liner can appropriately absorb the impact force at that time to protect the human head, regardless of which side the frontal head or the back of the head receives an impact. (For example, refer patent document 1).

  However, if the shock absorbing liner is provided between the cap body and the wearing body, the gap between the cap body and the human head becomes small, so the air permeability inside the cap body is poor, and the shock absorbing liner Heat dissipation is also hindered. For this reason, there is an inconvenience that heat build-up and stuffiness are generated inside the cap body and comfort at the time of wearing is impaired.

  Therefore, in order to ensure air permeability and heat dissipation, it is conceivable to remove the shock absorbing liner from the inner surface of the cap body.

  However, when the shock absorbing liner is removed, the impact force can be reduced by a hammock when a falling object collides from the position directly above the cap body, but it is received from a direction other than the top of the head when the wearer falls or falls. The impact force can hardly be absorbed, and sufficient safety performance for falling and falling as an industrial safety cap (safety cap for falling and falling protection specified in “Japanese Industrial Standard T811: 2000 Annex 2”) There is an inconvenience that cannot be obtained.

  On the other hand, in the safety cap before the provision of the industrial safety cap according to the Japanese Industrial Standard, the shock absorbing liner is not provided inside the cap body, and the outer peripheral surface of the headband constituting the wearing body (cap body) There is one in which a plurality of cushioning members are provided on a surface facing the surface (see, for example, Patent Document 2).

JP-A-8-311713 Japanese Utility Model Publication No. 33-1240

  However, in an industrial safety cap provided with an impact absorbing liner, the headband is generally located below the impact absorbing liner. For this reason, as shown in Patent Document 2, even if a buffer member is provided on the headband, it is difficult to place the buffer member at a position where it is necessary to absorb the shock. The shock absorption capacity equivalent to the industrial safety hat provided cannot be obtained. Therefore, even when the configuration of the safety cap found in Patent Document 2 is adopted, the shock absorbing liner cannot be removed in order to exert the protection performance at the time of falling or falling, and heat trapping and stuffiness inside the cap body can not be removed. It cannot be resolved.

  In view of the above-described points, an object of the present invention is to provide an industrial safety cap that has a sufficient impact absorbing capability and is less likely to be overheated or stuffy and has high comfort when worn.

  In order to achieve such an object, the present invention provides a hard cap body, a wearing body comprising a hammock and a headband provided inside the cap body and contacting the human head, and the wearing body and the cap body. An industrial safety cap comprising a protective pad positioned between and for absorbing an impact, wherein the protective pad includes an annular base and a shock absorbing structure portion provided on the base and having a predetermined shock absorbing capability. The base is disposed at a position higher than the headband and lower than the top of the hammock.

  According to the present invention, since the protective pad is configured by providing the shock absorbing structure portion on the annular base, the height position of the base can be set to a desired position, thereby absorbing the shock. It is possible to dispose the shock absorbing structure at a position where is necessary.

  Furthermore, since the base is disposed at a position higher than the headband and lower than the top of the hammock, a sufficient gap can be formed between the cap body and the hammock at the top of the head. According to this, the contact between the hammock and the inner surface of the cap body due to the impact load is prevented, and the impact mitigating action of the hammock is fully exhibited, as compared with the case where a conventional shock absorbing liner is provided. It is hard to get hot and stuffy. Therefore, according to the present invention, it is possible to provide an industrial safety cap that has a sufficient shock absorbing capability and high comfort when worn.

  In the present invention, it is preferable that the shock absorbing structure is detachably fixed to the base. According to this, it is possible to dispose the shock absorbing structure portion only at a desired position of the base, and do not provide the shock absorbing structure portion at an unnecessary position so that the space between the cap body and the wearing body is not provided. Breathability can be secured. Furthermore, since the base and the shock absorbing structure are separate, the base and the shock absorbing structure can be formed of an optimum material (synthetic resin material having different properties) that exhibits their respective functions.

  In the present invention, it is preferable that the shock absorbing structure is provided in at least two locations on the front side and the back side of the base. According to this, the shock absorption capability by the shock absorbing structure portion can be imparted to at least two locations on the frontal and occipital sides, and the fall / falling protection performance can be reliably obtained.

  In the present invention, it is preferable that the base is detachably fixed to the hammock. According to this, the structure for attaching the protective pad to the inner surface side of the cap body becomes unnecessary, and an increase in the manufacturing cost of the cap body can be prevented. Further, in the replacement work of the wearing body, the protection pad can be attached to and detached from the cap body together with the wearing body, and the handling thereof becomes extremely easy.

  In the present invention, it is preferable that the circumference of the base is adjustable. According to this, the circumference of the base can be adjusted to match the size of the cap body or hammock (especially the dimensions in the circumferential direction), and the protective pad can be easily attached even if the cap body or hammock size is different Can do. Further, when the shock absorbing structure of the protective pad is arranged at a desired height position in the space between the cap body and the wearing body, the circumferential length of the base can easily correspond to the circumferential length of the space. The shock absorbing ability by the protective pad can be surely exhibited at a necessary position.

Composed. The wearing body 3 is composed of a hammock 4, a headband 5, and a ring string (such as a chin strap) (not shown).

  The hammock 4 is integrally formed by injection molding using a synthetic resin (for example, a polyolefin-based synthetic resin) as a material, and forms a predetermined gap between the human head and the cap body 2 in contact with the human head.

  The headband 5 surrounds the human head and is fixed to the human head. A size adjusting means (not shown) is provided on the rear head side of the headband 5 so that the circumference of the headband 5 can be adjusted according to the size of the human head by the size adjusting means.

  The hammock 4 includes a plurality of (four in this embodiment) leg portions 6 that extend radially from the top of the head, and an annular leg joint portion 7 that integrally connects the upper ends of the leg portions 6. . At the lower end portion of each leg portion 6, there is provided a locking portion 8 that is detachably locked to a locking projection (not shown) provided on the inner surface of the lower end portion of the cap body 2.

  Each leg portion 6 is flat when deployed from the inside of the cap body 2 and is curved to correspond to the human head when assembled inside the cap body 2.

  A protective pad 9 is provided between the cap body 2 and the hammock 4. The protective pad 9 includes an annular base 10 and a plurality (four in this embodiment) of shock absorbing structures 11.

  The base 10 is formed in a band shape with the vertical direction as the width direction, and has a shape that gradually decreases in diameter from the lower end in the width direction toward the upper end. Thereby, it is provided along the outer surface of the leg portion 6 of the hammock 4.

  The shock absorbing structure 11 is a plate that connects a plurality of (six in this embodiment) tubular structure parts 12 disposed with a space allowing air to pass through and the bottoms of the tubular structure parts 12 to each other. And a base 13 having a shape. Each cylindrical structure portion 12 is formed in a polygonal cylindrical shape (in this embodiment, a hexagonal cylindrical shape), and has an ability to absorb an impact force by being crushed in the axial direction. The base 13 is provided integrally with the base 10.

  Moreover, each impact-absorbing structure part 11 is arrange | positioned between each leg part 6 of the hammock 4, as shown in FIG.1 and FIG.2. Thereby, when the protective pad 9 is located between the cap body 2 and the hammock 4, the respective shock absorbing structures 11 are arranged on the front head side, the back head side, the right head side, and the left head side of the cap body 2. It will be in the state arrange | positioned by the part side.

  In particular, the industrial safety cap 1 of the present embodiment has an industrial safety cap defined in Japanese Industrial Standards by disposing the shock absorbing structure 11 having the above-described configuration on the frontal and occipital sides. It is configured to provide sufficient fall / fall protection performance as a safety cap for fall / fall protection in “Japanese Industrial Standard T8131: 2000 Annex 2”.

The shock absorbing structure 11 can be reliably arranged.

  Although not shown, a part of the base 10 may be formed discontinuously, and an adjusting means for adjusting the peripheral length of the base 10 may be interposed at the discontinuous position. According to this, the circumference of the base 10 can be easily adjusted to the size of the cap body 2 and the hammock 4 (particularly the dimension in the circumferential direction), and even if the cap body 2 and the hammock 4 are of different sizes, it is easily protected. A pad 9 can be attached. Further, the outer dimension of the hammock 4 becomes smaller as the height becomes higher (closer to the top of the head), but the base 10 with respect to the leg 6 is adjusted by adjusting the peripheral length of the base 10 by the adjusting means accordingly. The height position of can be easily changed.

  In the present embodiment, the belt-like base 10 is shown, but the shape is not limited to the belt-like shape, and although not shown, the base may be formed by forming a rectangular or round bar-like one in a ring shape.

  In the present embodiment, the protective pad 9 in which the base 10 and the shock absorbing structure 11 are integrally formed is described. However, the present invention is not limited to this, and each shock absorbing structure 11 is attached to the base 10. It may be detachably provided. In this case, although not shown, a connecting means that can be connected to the base 10 and the shock absorbing structure 11 may be provided.

  By providing each of the shock absorbing structure portions 11 detachably with respect to the base 10, the base 10 and the shock absorbing structure portion 11 can be formed of different materials. Thereby, the optimal material (synthetic resin material which has a different property) which exhibits each function for the base 10 and the shock absorption structure part 11 can be selected and formed.

  Further, in the present embodiment, the hammock 4 and the protective pad 9 are detachably connected by locking the locking claw 15 provided on the base 10 to the slit 14 formed in the leg portion 6 of the hammock 4. Although an example has been shown, a connecting means different from the configuration of the locking claw 15 and the slit 14 may be used.
