Description

  The present invention relates to a board used for stand-up paddle surfing (hereinafter sometimes abbreviated as SUP), that is, a stand-up paddle surf board, and more particularly, to the above-described board in which puncture, air leakage, and the like are eliminated.

  SUP is performed using a board that is more stable than a general surfboard used for surfing (hereinafter referred to as a surfboard for SUP). As a marine sport to enjoy on the calm water surface, these days, for young men and women including children, It is gaining popularity.

Conventionally, a SUP surfboard is generally composed of a one-chamber air body manufactured using a water-tight / air-tight three-dimensional structure cloth (Japanese Patent Laid-Open Nos. 11-342447, 2002-337260, etc.). .
In other words, a SUP surfboard having an appearance similar to that of a surfboard is created in one air chamber using a three-dimensional structural cloth, and the air chamber is filled with air.

  In the case of such a configuration, air is filled at a high pressure so as not to bend even if a person gets on, so that the risk of air leakage and puncture increases. Also, even if the SUP is a gentle sport on the surface of the water, such as when there are floats with protrusions, or there are large floats or underwater structures without protrusions, etc. Contact with these sometimes causes cracks and breakage, and if these occur, air leakage and puncture occur, and there is a risk of submergence in a board composed of an air body with only one air chamber.

  In addition, in the case of a SUP board made of three-dimensional structural cloth, the air is drawn out and folded and transported or stored except when in use. This crease part may cause cracks and breakage, resulting in the danger described above.

In addition, in the case of SUP sports, in order to develop a further sense of balance, in recent years, stretching and yoga on the SUP board are frequently performed.
If such a motion is performed on the SUP board, naturally, problems on the surface of the SUP board, such as frequent occurrence of scratches due to friction, occur.

  On the other hand, as a board for surfing, a three-dimensional structure cloth is used and a structure having a two-chamber between the center and its surroundings (EP2808245A1), the front part is made of a hard material, and the rear part is a three-dimensional structure. There are also proposed ones made of a flexible material such as cloth, or ones made of a hard material for the front part and the rear part and made of the flexible material for the central part connecting them (WO2014 / 1991917A1).

However, in a board with two air chambers, if air leakage or puncture occurs in one air chamber, submergence is avoided to some extent because there is another air chamber, but it is difficult to prevent air leakage and puncture itself. is there. In addition, each air chamber is filled with air at a high pressure so as not to bend even if a person gets on it, and thus air leakage and puncture are likely to occur.
In addition, a board made of hard material only in the front part or in the front and rear parts is useful as a board for surfing where the water surface, directly under it, or the wave front is torn or requires high speed. However, in a board for SUP intended for calm marine sports, if the central portion with the highest load is made of flexible, air leakage and puncture are likely to occur.
Moreover, in the case of providing a keel in any of the boards having the two air chambers or the hybrid type of the hard material and the flexible material as described above, the keel is generally installed in the center portion. Therefore, it is provided in the portion of the flexible material, and since there is a role of imparting a drag force and a restoring force to the board, there is a very high possibility that breakage such as a crack will occur in the installation portion of the keel where a great load is applied.

JP 11-342047 A JP 2002-337260 A EP2808245A1 WO2014 / 1991917A1

  In consideration of the above points, the present invention suppresses the occurrence of cracks, breakage, fraying, etc. as much as possible in the SUP board, and even if an air leak or puncture occurs, it does not lead to submersion. Moreover, when it is desired to provide a keel, a fin, or the like, it is an object to provide a SUP board that can not only be easily damaged such as cracks but also facilitate the installation itself.

The board for SUP of the present invention is a stand-up paddle surfboard having a hard part, the central part is made of a hard synthetic resin plate, and the periphery of the central part is an air chamber part made of a water-tight / air-tight three-dimensional structure cloth It is characterized by comprising.
The air chamber part may be located at the front part and the rear part of the central part.
The rigid synthetic resin plate-like body may be a plate-like cylinder that is open in the front-rear direction, and the end of the air chamber is inserted into the plate-like cylinder, so You may comprise the board with which the chamber part was integrated.

According to the SUP board having a hard part of the present invention, there is an air chamber part made of a water-tight / air-tight three-dimensional structure cloth around the hard synthetic resin plate-like body in the center part. If there are multiple chambers, even if an air leak or puncture occurs in one of the air chambers, the rigid synthetic resin plate and other air chambers in the center will maintain buoyancy, resulting in submersion. There is no.
In addition, since a person who performs SUP (hereinafter referred to as a “rider”) generally rides on a hard synthetic resin plate-like body located at the center of the board of the present invention, the rider during the SUP may overload the board. Even if a load is applied, this load is received mainly by a hard synthetic resin plate-like body. For this reason, the shape of the board can be sufficiently maintained without filling the air chamber located around or around the center with high pressure. That is, since it is not necessary to fill the air chamber portion with high pressure, the risk of air leakage and puncture can be reduced. In particular, when stretching and yoga are frequently performed on the board, the above effects are great.
Further, when the keel is provided, it can be molded integrally with the hard synthetic resin plate-like body, so that the keel installation part and its peripheral part are not easily damaged, and the work of the installation itself is facilitated.

In the board of the present invention, since the air chamber portion made of the three-dimensional structure cloth is provided around the hard synthetic resin plate-like body, the weight of the board can be reduced.
Of course, if an air chamber portion made of a three-dimensional structural cloth is provided on both side portions together with the front and rear portions of the hard synthetic resin plate-like body, further weight reduction can be achieved.

  And, when the air chamber portion made of the three-dimensional structure cloth is provided on the front and rear portions of the hard synthetic resin plate-like body, the balance of the board itself can be improved even when it is provided on both sides, It is possible to provide a board that can be easily operated by children as well as men and women of all ages and that is easier to SUP.
