Description

  The present invention relates to a blade-proof / protective neck guard.

  In the present invention, the blade-proof / protective neck guard is used by a security / security worker to protect the neck from a weapon such as a knife, or a sports equipment such as ice hockey or in-line hockey (which can be said to be ice hockey). For example, it is a collective term for protective equipment called so-called neck guard, which is used to protect the neck from collision of the equipment in sports where the pack) may directly hit the body such as a player or referee. is there.

  Conventionally, a blade-proof upper garment and a protective jacket for protecting the body from the blade have been proposed (Patent Documents 1 and 2).

  However, these proposals are for protecting the upper body torso, there is no part for protecting the neck, and the protection for the neck, which is supposed to be a vital point, was originally insufficient.

  On the other hand, as a neck guard for protecting the neck portion from a blade or the like, a sheet-like material composed of a metal rope made of a plurality of metal strands is sewn at a side ground, and the sheet-like material is further connected to a metal rope. It is proposed to use a para-aramid fiber (Patent Document 3).

However, this proposal is still inadequate in terms of blade-proofing and overall configuration, especially in the proposed configuration, when the neck guard hits the chin and the back of the head even when the neck is moved back and forth. The shape is made so that there is no neck guard (Patent Document 3, paragraphs 0029 and 0030, FIG. 3), but in the shape where the neck guard does not hit the jaw or the back of the head, the protection is not fully applied. This means that there is a part, and in the event of an emergency, the success or failure of the protection of that part becomes a problem.

  In view of the above points, the object of the present invention is a blade-proof / protective neck guard that protects and protects the neck from a blade or a competition equipment that collides during sports competitions. The neck guard does not move even when it is turned or moved back and forth, and left and right, and it can maintain a fixed protection state, thus providing a neck guard that can always protect the V-shaped part of the lower jaw. There is.

  The blade-proof / protective neck guard of the present invention that achieves the above-described object has the following configuration (1).

(1) A neck guard that wraps the entire circumference of the neck with a belt and fixes the belt with a hook-and-loop fastener, and the upper edge of the belt is a portion of the neck corresponding to both sides of the neck. The prevention is characterized in that it is formed in a shape that becomes lower than the position, and gradually increases toward both sides of the neck or the highest part of the back of the neck with the lower part of the lower jaw as the lowest part. Blade and protective neck guard.

  In the neck guard of the present invention, more preferably, the neck guard has a specific configuration of any one of the following (2) to (4).

(2) The height difference H between the lowest position P ₁ of the portion corresponding to the lower chin of the belt and the highest position P ₂ of the both sides of the neck or the back of the neck is H = 30 mm to 50 mm. The blade-proof / protective neck guard according to (1) above, wherein

(3) at the lowest portion position P ₁ is a partial edge lines corresponding to the jaw lower part on the band body, above, wherein the width of the band body W ₁ is W ₁ = 80 mm ± 15 mm (1) Or the blade-proof / protective neck guard described in (2).

(4) At the highest position P ₂ where the upper edge line of the band is the both sides of the neck or the back of the neck, the width W ₂ of the band is W ₂ = 75 mm ± 15 mm, and The blade / protective neck guard according to any one of the above (1) to (3), wherein the distance W ₃ between the highest positions P ₂ is W ₃ = 300 mm ± 20 mm.

  According to the blade-proof / protective neck guard of the present invention, even when the neck part is violently turned left and right, back and forth, etc., it hardly follows or moves with the movement of the neck part. An unprotected part that is not guarded even momentarily is almost eliminated, and the neck and its surroundings can be well protected and protected from blades and competition equipment that collides during sports competitions.

  Hereinafter, the blade-proof / protective neck guard of the present invention will be described in more detail.

FIG. 1 is a schematic front model diagram showing one embodiment of the present invention as a model. The blade-proof / protective neck guard 1 of the present invention winds the entire circumference of the neck with a belt, It is fixed by the hook and loop fasteners 5 and 6, and the upper edge line L of the belt body is such that the position of the portion corresponding to the lower jaw 2 is lower than the position of the portions corresponding to both side portions 3 of the neck, and The lower chin 2 is the lowest part P ₁ , and it is formed in a shape that gradually increases toward the highest part P ₂ located on both side parts 3 of the neck or the rear part 4 of the neck. As described above, in the present invention, the upper edge line L of the belt body is set so that the position of the portion corresponding to the lower chin 2 is lower than the position of the portions corresponding to the both side portions 3 of the neck, and There is a big feature in that it is formed so that it is gradually raised toward the highest part of the neck part 2 or the back part 4 of the neck at the lowest part, and if it is formed in a staircase shape without gentle, This will lead to gaps that cannot effectively prevent blade protection and protection, and there will be room for the neck guard to move even when the wearer turns his neck or moves his / her neck back and forth. It is difficult to achieve the intended purpose of the present invention to obtain a neck guard that is stationary and does not move as the neck moves.

In addition, in terms of the height difference of the upper edge line of the band, the height difference H between the lowest position P ₁ and the highest position P ₂ corresponding to the lower part of the chin may be within a range of H = 30 mm to 50 mm. Preferably, it is 30 mm to 40 mm.

In the present invention, “slowly increasing” means that a line (flat line) parallel to the horizontal direction is substantially the length in the upper edge line L from the lowest part P ₁ to the highest part P _2. Say that it has not continued for more than 5cm.

In addition, at the lowest position P ₁ where the upper edge line of the band corresponds to the lower part of the chin, the width W ₁ of the band is preferably W ₁ = 80 mm ± 15 mm.

Further, at the highest position P ₂ where the upper edge line of the belt is on both sides or the back of the neck, the width W _{2 of the} belt is W ₂ = 75 mm ± 15 mm, and The distance W ₃ between the highest position P ₂ is preferably W ₃ = 300 mm ± 20 mm.

  In the present invention, the material constituting the belt body is not particularly limited as long as the blade-proof / protective effect is recognized, and for example, high-strength fiber felt, woven fabric, or knitted fabric can be used. . Other than these, FRP plates (fiber reinforced plastic plates) and metal plates that are soft and flexible to some extent can also be used.

In particular, according to the knowledge of the present inventors, high strength fibers are contained in the band body at a basis weight of 50 to 1000 g / m ² , more preferably, high strength fibers are contained at a basis weight of 250 to 800 g / m ² . It is preferable to use a felt shape and / or a woven fabric or a knitted fabric because the feeling in use is good. Here, the high-strength fibers include, for example, aromatic polyamide fibers, high-strength polyethylene fibers, titanium fibers, poly-para-phenylenebenzobisoxazole fibers, ceramic fibers, and the like, and the high-strength fiber fabrics. Are coated with silicon carbide or the like. In the present invention, the aromatic polyamide fiber is preferably a para-aromatic polyamide fiber from the viewpoint of blade prevention / protective effect.

  The thickness of the belt body is determined substantially corresponding to the magnitude of the specifically required dustproof / protective effect, but in general, the thickness is preferably about several mm to 20 mm, more preferably It is about 5 mm to 15 mm, and most preferably about 5 mm to 10 mm. This thickness is preferably within the above range, generally thicker as much as possible because it can more firmly demonstrate the fixed state of not moving with the movement of the neck and the protective effect is also increased. However, it is also important to keep the thickness so that the wearer feels comfortable (not feeling cramped).

  In addition, the band may have a plurality of layers. In this case, all the layers may be the same material layer, but may have a laminated structure in which different material layers are combined, for example, from an inner core layer and an outer layer. The outer / inner core layer is made of metal or metal fiber, or made of FRP plate or metal plate, and the outer layer is made of fiber (high strength fiber or normal strength fiber) (felt or woven fabric). Alternatively, a knitted fabric or the like may be arranged.
