Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an uphole line for board sailing. An uphaul line is a rope used to pull up a sail in the event of a fall in board sailing.

When sailing with a board, if you use a long rope, the rope may hang down in the water, reducing sailing effectiveness, or become dangerous as it may wrap around your legs. However, if the sail falls onto the water surface due to an operational error, a 2 to 3 meter rope is required to right the sail.

Therefore, if you have an elastic rope that is as short as 1 m 30 cm to 1 m 50 cm while sailing, and can be extended to 2 m to 3 m when the sail falls on the water surface when it falls and needs to be re-righted, it will contract during sailing and stretch when it falls. Convenient and safe.

Conventional methods use cross ropes or braided ropes with a thickness of about 10 mm to 20 mm, either by processing both ends and tying them to a shock cord, or by inserting rubber cords into the braided ropes to shrink the side threads. has been used. However, if a cross rope or braided rope is used as is, it is dangerous because the rope will hang down into the water surface, so it is not used much at present. The current mainstream line is a cross rope or a braided rope with both ends processed and tied to a shock cord, or an uphole line in which a rubber cord is inserted into the core of the braided rope and the side threads are contracted.
However, while these uphaul lines are elastic and easier to use during sailing and during falls, they do not significantly reduce the force required to right the sail in the event of a fall. Therefore, the current situation is to make and use knots to make it easier to rebuild the sail.

In order to eliminate these drawbacks, the present invention inserts a buoyant body inside the rope that is easy to grip, and changes the tension between the rope itself and the synthetic fiber bundle, and the tension applied to elastic fibers such as rubber or synthetic resin. This is an uphole line that is made stretchy by simultaneously making the string. In addition, because there is a stretchable cushion material between the buoyant body with an easy-to-grip shape and the elastic cylindrical braided body, the buoyant body and the side biased body are integrated, so it is different from conventional braided cords. It is easier to balance the forces needed to right the sail than a rope with a rubber cord inserted into the core, and even women can easily right the sail.
In addition, because synthetic fibers and elastic fibers such as rubber or synthetic resin are woven at the same time, the rope has a soft and voluminous appearance, is less slippery, easier to grip, and has more functionality than conventional products. Excellent in both properties and fashion. In addition, a buoyant body is inserted into the handle, so even if the sail falls down, the uphole line will not sink into the water, and will float on the water surface.
It also has the feature of making it easy to grab the uphole line. The object of the present invention is to provide an uphaul line that can rebuild the sail very efficiently as described above and also provides fashionability.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a simplified diagram of a core material having unevenness and buoyancy. 1 indicates a buoyant body, which is used to float the uphole line of the present invention on the water surface and to make it easier to hold.The shape and material are not particularly limited, but it may be a streamlined body made of synthetic resin or a long egg shape. The crushed shape is good. The fiber bundle 2 is arranged so as to wrap around the buoyant body 1, and the fiber bundle 3 is wound spirally thereon to temporarily fix the buoyant body 1.
The fibers and fiber bundles mentioned in points 2 and 3 are preferably fibers with a non-slip surface, preferably spun yarns such as polypropylene or vinylon. Furthermore, in order to completely fix the buoyant body, parts of the buoyant body are glued with adhesive 4, and 1, 2, and 3 are fixed. The core material having unevenness and buoyancy is constructed as described above.

FIG. 2 shows a simplified diagram of a fiber bundle braided into a cylindrical shape of the side material, 6 is a synthetic fiber bundle, and 7 is an elastic fiber such as rubber or synthetic resin. 6 and 7 are wound on separate bobbins, and the tension applied to each thread can be adjusted to give it elasticity. In addition, when using this string making method, 2 to 3
It is now possible to manufacture elastic ropes that are 4 to 7 times more elastic than rubber strings and shock cords, which can only be about twice as elastic.

FIG. 3 shows an embodiment of the present invention, and is a partially cutaway front view. 1 is a buoyant body, 2 is a fiber bundle, 3 is a spirally wound fiber, and 4 is an adhesive. 5 is a fiber bundle with elasticity, which expands and contracts in accordance with the expansion and contraction of the side material, to improve matching with the core material shown in Figure 2, and to make it easier to hold when gripping the uphole line. It is also used as a cushion material. As for the material, polypropylene, nylon, polyester, etc. processed into a wave shape are suitable, but there is no particular limitation as long as it is a stretchable fiber bundle. 6 is a synthetic fiber bundle, and 7 is an elastic fiber such as rubber or synthetic resin.
