Description

{Prefabricated windsurfing}

The present invention relates to a prefabricated windsurfing, and more particularly, to a prefabricated windsurfing capable of easily disassembling and assembling a windsurfing hull by a prefabricated method and securing safety at the time of navigation of a wad.

In general, windsurfing (board sailing) is a marine leisure sport that takes the wind in the wind while sailing on a board, similar to a yacht, but is known as a more dynamic sport because it can fly or spin.

Windsurfing is a sport in which a mast is set on a constant plate and the wind is blown. It is characterized by moving the mast using a hinge that moves away from the stereotypes of fixing the mast vertically. In other words, yacht and surf are exquisitely combined, and today they are enjoying almost all over the world.

Even with minimal natural conditions to enjoy such windsurfing, there must be a wind of moderate intensity. Therefore, windsurfing can not be enjoyed on weak or rare winds. In order to enjoy windsurfing even in windy conditions, it is necessary to learn the technique of using sails to adjust wind direction.

Small water sports such as small yachts, boats, canoe kayaks, surfing and windsurfing enjoy a wide variety of water sports rather than a particular sport.

According to these characteristics, techniques for enjoying water sports using various small ships more conveniently are being developed.

Prior art relating to a prefabricated boat is disclosed in Korean Patent No. 10-0538706.

The prior art separates the inside and the outside of the hull, divides the inside into three parts by air injection type, and surrounds the outside part. Also, as disclosed in Korean Patent Laid-Open Publication No. 10-2012-0036378, the structure of the boat is divided into three parts and joined to the projections through support bands. These structures are about technologies that split the boat to make it easier to move and store. US Patent No. US2008 / 00041295 A1 (Feb. 21, 2008), a technique of constructing a hull as a frame and assembling it and enclosing the outside with an envelope is also being developed.

The technology of the boat hull which can be separated and assembled can be applied not only in terms of improving the convenience of storage and transportation but also in the structure for a multifunctional multipurpose.

For example, Patent Document 1 below discloses a multi-purpose leisure boat hull structure of a block connection type.

The multi-purpose leisure boat hull structure of the block connection type according to the following Patent Document 1 is a kayak, a boat or a surfing board for leisure purpose. The structure is provided with a connecting portion, a fixing portion, A stern portion including a connecting portion, a fixing portion, and a top plate cut-off portion in a structure corresponding to a rear portion of the ship, and a stern portion connected between the forward portion and the stern portion, A seating portion including a connecting portion for connecting the seat connecting groove and the fore and aft portions so that the seat can be placed, and a fixing portion, a seat having a seat connecting portion 41 fixed to the boarding portion, And a furnace which is a means for pivoting the boat forward and backward, and a fore and aft portion, The tails 20 are connected to each other, a bow section and the stern top plate cut part windsurfing kit of the top plate section having a concave-convex portion is inserted (凹凸) structure of the sail to the fixed plate to be coupled.

In the following Patent Document 2, a 'prefabricated boat' is disclosed.

The prefabricated boats according to the following Patent Document 2 have a body portion composed of a plurality of powders that can be engaged, an enclosure enclosing the exterior of the body portion in a state where the body portion is integrally coupled, And an air tube that bulges when air is injected.

Wherein the outer portion is made of a reinforcing fiber having a shape of a bag provided with an opening for receiving the powders constituting the body portion and subjected to a waterproof coating treatment and is made of reinforcing fibers which are joined at a predetermined position around the opening, And a connecting portion.

The body portion has a convex end face formed by an upward sloping face and a downward sloping face at one side of the powder to be mutually coupled, and a concave end face corresponding to the shape of the convex end face is formed at one side of the other powder to be coupled thereto. A coupling protrusion formed on one of a convex end face or a concave end face formed on one side of the powder to be mutually coupled; And a projection receiving part formed in the other powder to be coupled thereto and accommodating the coupling projection part.

Korean Utility Model Publication No. 20-2013-0007396 (published on December 27, 2013) Korean Patent Publication No. 10-2005-0063252 (published on June 28, 2005) Korean Utility Model Publication No. 20-2011-0010414 (published on November 4, 2011) Korean Utility Model Publication No. 20-2009-0009531 (published on September 23, 2009)

However, in the multi-purpose leisure boat hull structure of the block connection type according to the prior art 1, the forward portion, the stern portion and the boarding portion are separated and combined so that they can be conveniently stored and moved. However, There is a problem that windsurfing using wind can not be carried out and a boat having a long length and a narrow width is frequently rolled up and rolled down frequently, and the passenger can not secure the passenger safely.

In addition, the prefabricated boats according to the prior art 2 have advantages of easy assembling, disassembling, storage and transportation, but can not wind-surf using winds, and have a long and narrow boat, There is a problem that the passenger can safely ride the vehicle safely.
