Disclosure of Invention

However, the conventional protective pad described above is considered to be able to absorb an impact when the impact is applied to the entire outer surface thereof, but has a disadvantage that the impact cannot be sufficiently absorbed when the impact is applied to a part of the outer surface thereof.

Further, although there is a demand for changing the area of the pad abutting on the waist portion in accordance with a difference in the human body or the like, it is not economical to prepare a plurality of protection pads having different sizes in order to satisfy the demand.

Further, in order to improve the wearing feeling, it is preferable that the pad is deformed into a shape along the curved surface of the waist portion when it is in contact with the waist portion.

Accordingly, a primary object of the present invention is to provide a shock absorber for a protective pad, which can protect a protective portion such as a waist portion and a thigh portion well even when an impact is received intensively in a small area, and in addition, a secondary object of the present invention is to provide a shock absorber for a protective pad, which can closely contact the protective portion, can realize air permeability of the contacted protective portion, and can increase or decrease a contact area with the protective portion, and a protective pad and protective clothing using the same.

Detailed Description

Preferred embodiments for carrying out the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a shock absorber for a protective pad according to an embodiment of the present invention,

fig. 2 is an exploded perspective view thereof, fig. 3 is a sectional view taken along the line I-I shown in fig. 1, and fig. 4 is a sectional view taken along the line II-II shown in fig. 3.

A shock absorber (hereinafter, simply referred to as "shock absorber") a for a protective pad according to an embodiment of the present invention is used for a protective pad B described later, and is configured such that a shock dispersing member 2 for dispersing an impact applied from the outside is embedded in a shock absorbing member 1 for absorbing and cushioning the impact.

In the present embodiment, the term "shock absorption and relaxation" refers to low rebound, and absorbs and relaxes a shock received over a large area from among shocks applied from the outside, particularly from the entire outer surface of the shock absorber a.

The term "dispersed impact" refers to a dispersion of an impact which is received from an impact applied from the outside, particularly, in a concentrated manner in a small area on a part of the impact absorber a. In other words, the impact force applied to the unit area is reduced.

The shock absorbing member 1 has a three-layer structure in which cushioning members 4 and 5 having different repulsive forces are bonded to both surfaces of a base material 3, and is formed into a regular hexagonal plate-like body having a size of about 11 (mm) in thickness t, with a dimension W1 between side wall surfaces of 45 (mm), a dimension W2 between opposing top portions of 52 (mm (ミリ), and a thickness t.

The shock absorbing member 1 is not limited to the regular hexagon shown in the present embodiment, and may be formed in a convex polygon, a concave polygon, or an irregular polygon. Further, the shape is not limited to the polygonal shape, and may be a new circle (new Yen shape), an oval shape, or the like.

The base material 3 is formed of an acrylic foam having a thickness of approximately 1 (mm), and has a housing hole 3a formed in the center thereof and circular vent holes 3c … … formed in four sides thereof.

The housing hole 3a is formed by intersecting the grooves 3b having a width W3 of 10 (mm) and a length L1 of 36 (mm) in a cross shape. The impact dispersing member 2, which will be described in detail later, can be positioned by accommodating the impact dispersing member 2 in the accommodating hole 3 a.

The cushion member 4 is formed of a plastic foam such as a highly foamed low resilience urethane foam having air permeability and having a thickness of approximately 7 (mm), and the cushion member 4 is opposed to a protection portion (not shown). In addition, circular vent holes 4a … … are formed at positions of the vent holes 3c … … facing the substrate 3.

The cushion member 5 is formed of a plastic foam such as a polyethylene foam having closed cells with a thickness of approximately 3 (mm), and circular vent holes 5a … … are formed at positions facing the vent holes 3c … … of the base material 3.

The impact dispersion member 2 will be explained. Fig. 5 is an enlarged front view of the impact dispersing member 2, fig. 6 shows details of the coil constituting the impact dispersing member 2, fig. 6(a) is an enlarged front view thereof, and fig. 6(b) is a cross-sectional view taken along the line III-III shown in fig. 6 (a).

As shown in fig. 5, the impact dispersing member 2 is formed by combining metal coils 6 and 6 made of, for example, SUS304 having a wire diameter of about 0.6 (mm), a length of 37 (mm), and a width of about 10 (mm) in a cross shape and joining intersecting portions 6c thereof by, for example, spot welding.

The coil 6 is formed by winding two metal wires 6a and 6b wound in opposite directions in a coil shape while being shifted in position from each other to form a release portion β where they overlap and a gap portion α where they do not overlap, and by pressure-bonding the two metal wires so that the entire coil is flattened.

The "flat overall" means that the coil 6 is flat and flat portions are formed on the metal wires 6a and 6b themselves, and in fig. 6, the flat portions formed on the metal wires 6a and 6b are denoted by 6a 'and 6 b'. In addition, the metal wires 6a and 6b may not have flat portions, and only the coil 6 may be flat.

Specifically, the metal wire material 6a wound in a left coil and the metal wire material 6b wound in a right coil are wound while being shifted in position by the length e1 in the width direction and shifted in position by only the length e2 in the length direction.

In the impact dispersing member 2 having the above-described structure, since the metal wires 6a and 6b wound in different directions are combined, the metal wires 6a and 6b are densely formed with each other, the heat conductivity is improved, and the heat radiation performance is also improved. Further, since the two metal wires 6a and 6b are entangled with each other, the form of the impact dispersion member 2 itself is relatively stable, and the coil 6 is not stretched in relation to strength or the like when it is pressure-bonded.

Further, since the impact dispersing member 2 itself is formed flat, it is easily bent along with the deformation of the base material 3 and the cushioning members 4 and 5. In other words, even when the shock absorbing member 1 is embedded, the shock absorbing member 1 is bent and deformed together with the shock absorbing member, which contributes to improvement of wearing feeling.

Further, since the weight per unit area can be reduced as compared with a flat plate or the like of the same size, the weight can be reduced. Since the gap portion α is formed in the gap between the metal wires 6a and 6b, the gap portion α functions as a ventilation path through which air or the like flows, and heat can be quickly released to the outside.

Next, a protection pad according to an embodiment of the present invention using the above-described shock absorber for a protection pad will be described. Fig. 7 is a front view of the protective pad, and fig. 8 is a sectional view taken along the line IV-IV shown in fig. 7.

The protective pad B according to an embodiment of the present invention is for protecting a portion to be protected such as a waist portion or a thigh portion from an impact applied from the outside, and is configured such that the impact absorbers a for the protective pad, which are formed in polygonal shapes having the same shape and the same size as each other, are arranged close to each other and accommodated in the exterior member 7 so as to have a predetermined area covering the portion to be protected such as a waist portion.

The "protective region" is not limited to the waist and thigh illustrated above, but includes a concept of a shoulder, a wrist, a head, a knee, a chest, or the like.

The protection pad B is formed by using 7 of the above-described shock absorbers a for a protection pad, arranging the side wall surface a ' of the other shock absorber a for a protection pad on the side wall surface a ' of the one shock absorber a for a protection pad so as to face the side wall surface a ' thereof in proximity thereto, housing them in two circular cloths 7a and 7a made of cotton or the like having good air permeability, and sewing them.

The term "close" as used herein includes a state in which the side wall surfaces a 'and a' of the impact absorber a for a protective pad are in contact with each other via the outer bag member 7, while maintaining a required interval therebetween.

The number of the impact absorbers a for a protective pad is not limited to the above 7, and may be increased or decreased so as to have a predetermined area covering a portion to be protected such as a waist portion to be protected.

The seam portion is an outer edge portion between the outer edge portion of the outer bag member 7 and the side wall surface of the protective liner B … … in the vicinity, and these portions are indicated by seam lines 8, 9, and 10.

In addition to the side wall surfaces of the shock absorber a for a protective pad being kept at a required interval from each other, by sewing the side wall surfaces of the shock absorber a … … for a protective pad and the outer edge portion of the shock absorber a … … for a protective pad, the shock absorber a … … for a protective pad can be fixed well to the exterior bag member 7, and the shock absorbers a for a protective pad can be allowed to relatively tilt along the curved surface of the protection portion such as the waist portion where they are in contact with each other. Therefore, the impact absorbers a … … for a protective pad are in close contact with the protection portions, respectively, and the wearing feeling is improved.

In the present embodiment, the description has been given taking as an example a configuration in which the protection pads formed in the polygonal shapes having the same shape and the same size are arranged close to each other so as to cover a predetermined area of the protection portion, but the protection pads having different sizes may be arranged close to each other and densely.

The protective pad B having the above-described structure may be attached to underwear via a so-called hook and loop fastener (registered trademark), but is preferably used in the following manner. Fig. 9 is a front view of the gusset storage pocket, and fig. 10 is an explanatory view showing a state in which the protective clothing in which the protective gusset is stored in the gusset storage pocket is worn.

As shown in fig. 10, a protective garment 10 according to an embodiment of the present invention is configured such that pad receiving portions 11 and 11 for receiving the above-described protective pad B are provided at positions on the back side opposite to the waist (protective region) when worn.

As shown in fig. 9, the gusset receiving pocket 11 is formed in a slightly elongated shape having a size capable of receiving the protective gusset B, and is formed of a mesh having good air permeability, and the outer edge portion is sewn to the back surface of the undergarment 12 in a state where the lower portion of the upper member 11a and the upper portion of the lower member 11B are overlapped by a necessary dimension L2. The upper member 11a and the lower member 11B overlap each other by a required dimension to form a receiving opening for the protective packing B.

As shown in fig. 10, if the protective garment 10 in which the protective pad B is accommodated in the pad accommodating pockets 11, 11 is worn, the protective pad B is just opposite to the waist. The impact absorber a for a protective pad B facing the waist portion is relatively inclined along the curved surface of the waist portion with which it is in contact, and the entire protective pad B is in close contact with the waist portion. This provides a good wearing feeling and also provides a good waist protection.

The present invention is not limited to the above-described embodiments, and can be modified as follows.

In the above-described embodiment, the impact dispersing member has been described as a structure in which the metallic coils are combined in a cross shape and the intersecting portions thereof are joined by spot welding or the like, for example, but the impact dispersing member may be a structure in which the coils are formed in a single body or in a circular shape.
