Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a helmet.

[0002]

2. Description of the Related Art A helmet used for riding a motorcycle or the like has an outer shell cap body and an interior covering member provided on the inner surface of the outer shell cap body. In most cases, the outer shell cap body is made of resin, and as the inner body, a sponge single layer, a styrofoam single layer, or a composite layer of these is used properly according to the site.

[0003]

In spite of the fact that the sponge is porous in the interior body, the degree of close contact with the head is high, so heat is likely to accumulate and air permeability is difficult to obtain. It has the drawback that it easily loses its shape. on the other hand,
Styrofoam has the advantage that it can be breathable by providing irregularities and through holes on the surface that contacts the head, and that it does not easily lose its shape, but it has a higher functionality as shock absorbing power. However, there is a problem that the helmet becomes heavy by using styrofoam in a wide range.

From the above, the individual use as individual layers or composite layers has been achieved as described above. However, as an interior body, it is difficult to lose its shape, including the point of wanting to properly reduce the degree of adhesion while maintaining a good fit with the head (that is, to maintain an appropriate cooling and ventilation effect), There are some parts that you want to satisfy in terms of high shock absorption, weight reduction, etc. (for example, the part corresponding to the back of the head).

Therefore, in the past, it was sometimes necessary to sacrifice, for example, weight reduction for such a portion. The present invention has been made in view of the above circumstances, and an object thereof is to provide a helmet capable of satisfying all required functions as an interior body.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the present invention according to claim 1, in the helmet in which the inner jacket is provided on the inner surface of the outer shell cap, a part or the whole area of the inner jacket is formed by the cushioning material, and the cushioning material is It is characterized in that a board material formed by arranging a plurality of rod-like elastic materials formed by winding a thin strip material in a coil spring shape in parallel is formed in a single layer or a plurality of layers.

As described above, since the cushioning material is formed of the board material made of the rod-shaped elastic material, a large number of gaps are formed on the front and back surfaces of the cushioning material due to the winding structure of the rod-shaped elastic material. There is. Of course, this gap penetrates the cushioning material in the thickness direction. Therefore, it goes without saying that an appropriate cooling and ventilation effect can be obtained through this gap and the weight can be reduced.

Moreover, since the rod-shaped elastic material has elasticity in the radial direction, it exhibits a predetermined shape retention (elasticity) strength when a slow load is applied to the cushioning material in the surface direction. On the other hand, when a rapid load (impact) is applied, the rod-like elastic material is easily elastically deformed into a flat shape and, in some cases, plastically deformed. As a cushioning material, these have an epoch-making effect of preventing the shape from being lost when the helmet is repeatedly attached and detached, while exhibiting high shock absorption in an accident or the like.

When the radial deformation of the rod-shaped elastic member is within the elastic limit, there is an advantage that the shock absorbing action can be repeatedly exerted, that is, the helmet can be reused. On the other hand, since the rod-shaped elastic material is expandable and contractible in the axial direction and has flexibility, when the shock-absorbing material is assembled to the outer shell cap body, it should be made to correspond to the three-dimensional curved surface of the outer shell cap body. There is an advantage that it is easy to get familiar with the head.

Further, in the manufacture of the board material, since the thin strip material is wound in the shape of a coil spring and the obtained rod-shaped elastic materials are arranged and adhered, the manufacture of the cushioning material as a whole is simplified and the cost is reduced. There is an advantage that can be achieved. Needless to say, the shock absorbing material can be improved in shock absorption by forming the board material into a multilayer structure.

The cushioning material can be formed by laminating a plurality of board materials having different diameters of the rod-shaped elastic material as a material (claim 2). For example, a small-diameter rod-shaped elastic material is used for the board material facing the outer shell cap, and a large-diameter rod-shaped elastic material is used for the board material facing the head. By doing so, it is possible to absorb the impact from the shell side in a stepwise manner, and it is possible to obtain a reasonable and reliable impact absorbing action.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a helmet 1 which is one of the embodiments of the present invention. The helmet 1 includes an outer shell cap body 2 and an interior body 3 provided on the inner surface thereof. It is configured.

The outer shell cap body 2 is formed of, for example, PP, ABS, another resin material, FRP, or the like, and in this respect, it is substantially the same as the conventional one. Interior body 3
The enclosing member 6 has an enclosing member 6 provided in such a shape as to outline the contour on the inner surface of the outer shell cap body 2, and a cushioning member 7 accommodated inside the enclosing member 6. The enclosure 6 is made of styrene foam, sponge, or the like. The surrounding material 6 may be omitted.

The cushioning material 7 has a plurality of layers (three layers in the drawing) of which the thickness gradually increases from the side facing the outer shell body 2 to the side facing the head. , 10 are laminated. These board materials 8,
As shown in FIG. 3 and FIG. 4, 9 and 10 are formed by arranging and fixing a plurality of rod-shaped elastic members 11 each having a coil spring shape so as to be adjacent to each other in the longitudinal direction. Such a rod-shaped elastic material 11 is made by spirally winding a thin strip material formed of a light metal such as an aluminum-based material, and the fixing method is appropriate such as welding, adhesion, welding or the like.

The rod-like elastic member 11 is the one that is the thinnest and has the smallest winding pitch in the board member 8 on the side facing the outer shell cap body 2, and the board members 9 and 1 on the side facing the head.
About 0, gradually thicker and coarser winding pitch is used. The respective board members 8, 9 and 10 are fixed to each other at the portions of the respective bar-shaped elastic members 11 that abut.

It is to be noted that such board members 8, 9 and 10 are fixed while being bent in accordance with the three-dimensional curved surface of the outer shell cap body 2 from the bar-shaped elastic member 11 in the process of manufacturing the individual board members. The outer shell cap body is used as a separate board material or after laminating the board materials after the stick-shaped elastic members 11 are fixed so as to make each board material into a flat plate state. It is possible to employ any method such as a method of bending according to the two-dimensional three-dimensional curved surface.

Thus, the interior body 3 of the helmet 1 is
Part of it is a board material 8, 9 made of a rod-shaped elastic material 11,
Since the cushioning material 7 formed by 10 is used, in this cushioning material 7, there are many through gaps in the thickness direction due to the winding structure of the rod-shaped elastic material 11, and therefore the interior As a whole, the object 3 can have an appropriate cooling and ventilation effect through this gap and can be reduced in weight.

Moreover, since the rod-shaped elastic material 11 has elasticity in the radial direction, when a slow load is applied to the cushioning material 7 in the surface direction, a predetermined shape-retaining (elasticity) strength is exerted. On the contrary, when a rapid load (impact) is applied, the rod-shaped elastic material 11 easily exhibits elastic deformation or plastic deformation into a flat shape. These are epoch-making effects that, as the interior body 3 (the cushioning material 7), prevent the shape of the helmet 1 from losing its shape when the helmet 1 is repeatedly attached and detached, while exhibiting high shock absorption in the event of an accident. Will be played.

When the radial deformation of the rod-shaped elastic member 11 is within the elastic limit as described above, there is an advantage that the shock absorbing action can be repeatedly exerted, that is, the helmet 1 can be reused. is there. Further, since the rod-shaped elastic material 11 is expandable and contractible in the axial direction and has flexibility, when the cushioning material 7 is assembled to the outer shell cap body 2,
There is an advantage that the outer shell cap body 2 can be easily adapted to the three-dimensional curved surface, and the inner shell 3 as a whole can be easily assembled to the outer shell cap body 2. Further, there is also an advantage that it is easy to form the shape so that it fits well with the head, and a fit feeling without rattling can be obtained.

It is needless to say that the shock absorbing material 7 has a multi-layer structure of the board members 8, 9 and 10 and therefore has a higher shock absorbing property, but as described above, each board member 8, The outer shell cap body 2 due to the difference in wall thickness between 9 and 10.
It can be said that the impact from the side is absorbed in stages.
That is, the rod-shaped elastic material 1 having a small diameter that has a strong elasticity and is hard to be deformed
The board material 8 provided with 1 first absorbs the shock, and then the board material 9 provided with the rod-shaped elastic material 11 of medium and large diameter reabsorbs the shock that is damped to some extent by the board material 8 and finally,
The board material 10 having a large-diameter rod-like elastic material 11 and having high flexibility (deformability) provides a reasonably and surely shock-absorbing action such as performing final shock relaxation to the head. Will be obtained.

The shock absorbing power of the cushioning material 7 can be adjusted by the material, the wall thickness, the width dimension, the winding diameter, the winding pitch, etc. of the thin strip material which is the material of the rod-shaped elastic material 11. . By the way, the present invention is not limited to the above embodiment. For example, as the cushioning material 7, the board materials 8, 9, 1
It is possible to change the order in which 0s are stacked, to make the respective wall thicknesses the same, or to stack the board materials so that the directions of the rod-shaped elastic members 11 intersect.

Further, it is possible to appropriately increase or decrease the number of layers of the board materials to each other, and in some cases, it is possible to form the cushioning material 7 by a single-layer board material 12 as shown in FIG. However, the board material 12 in this case is the rod-like elastic material 11
Since it is necessary to make the diameter of the tape large so as to correspond to the desired thickness as the cushioning material 7, it is possible to increase the elasticity in the thickness direction, shape retention strength, etc. by making the winding pitch finer by that amount. preferable.

The cushioning material 7 is a helmet 1 as shown in FIG.
It may be divided into a head top 7A and a back head 7B. Even in this case, since the cushioning material 7 itself has elasticity along the surface direction, the resistance to strength does not decrease due to the divided structure. Buffer material 7
Is partially used as 7A for the crown portion, 7B for the occipital region shown in FIG. 6, or for other parts, and the interior body 3 is configured by providing styrofoam, sponge or the like on the other parts. Good.

The thin strip material for forming the cushioning material 7 is not limited to light metal, but titanium, resin, paper or cloth impregnated with resin, or the like can be appropriately changed. Although not shown, cushioning material 7
Permeability of porous materials, perforated materials, net materials, etc. to the front and back surfaces (particularly the surface facing the head) and between board materials when multiple layers of board materials 8 are provided. It is also possible to attach a sheet to make the fogging comfort suitable. This is also advantageous in that the cushioning material 7 has a high strength against a slow load or a local load and is prevented from being deformed when the helmet 1 is handled or detached.

[0025]

As is apparent from the above description, claim 1
In the present invention described, a cushioning material is provided in a partial area or the entire area of the interior object provided on the inner surface of the outer shell cap, and the cushioning material is a board material made of a coil spring rod-like elastic material. Since it is formed, the rod-like elastic material not only provides an appropriate cooling and ventilation effect through the through gap in the thickness direction, but also achieves weight reduction, and also exhibits a predetermined shape retention strength for slow loads. The epoch-making effect that the shape collapse is prevented, the high shock absorption property against a rapid load (shock) is exhibited, and it is possible to prepare for an accident or the like is obtained.

Further, since the rod-shaped elastic member is expandable and contractible in the axial direction and has flexibility, it is easy to correspond to a three-dimensional curved surface, and the cushioning member can be easily assembled to the outer shell cap body. There is also an advantage that it is easy to get familiar with the head.
Further, in the manufacture of the board material, the strip material is wound into a coil spring shape, and the obtained rod-shaped elastic materials are simply arranged and bonded, so that the manufacturing of the cushioning material as a whole can be facilitated and the cost can be reduced. There is.

From the above, it is possible to meet all the requirements as an interior body by properly using this cushioning material. When the cushioning material is formed by laminating a plurality of board materials having different diameters of the rod-shaped elastic material as a material (Claim 2), it can be said that the shock from the outer shell cap side is gradually absorbed. You can obtain a shock-absorbing effect that is reasonable and reliable.
