RU74110U1 - INFLATABLE SAIL WINDWINDER - Google Patents

Abstract

The utility model relates to multifunctional devices designed to move and rest on the water surface, as well as on the shore of a reservoir. The technical result consists in the development of an inexpensive, safe, convenient to use and transport device that can be used both independently and as a sail for a floating facility (boat, raft, etc.), and also as an awning for relaxing on the shore of a reservoir. An inflatable sail Vetvinder is two arcs 1 (Figure 1), made in the form of inflatable arc cylindrical elements interconnected by at least three jumpers 2, made in the form of inflatable cylinders of smaller diameter. On the outer side of the arcs and extreme jumpers, sail 3 is made of transparent material. At the ends of the arcs made elements (narrowing, expansion, loop, etc.), allowing to securely fasten the ends of the four lines 4, which are in a certain way combined at a certain distance from the sail.

Description

The utility model relates to multifunctional devices designed to move and rest on the water surface, as well as on the shore of a reservoir.

It is known from application No. 9511834 an inflatable liferaft containing a body of two buoyancy chambers made in the form of tubular closed shells and an inflatable bottom between them, an inflatable tubular closed shell occupying a position between the buoyancy chambers on the outside, with the ability to move in a vertical position in both the sides of the bottom, forming racks to maintain the awning, and the awning attached to the tubular closed shell (racks) and the buoyancy chamber, and the buoyancy chambers are made with relative size 1.0 mi <L / B <1.5, 10 <A / F <15, and the weight ratio of the raft to its passenger capacity of not more than 4.0.

The known device is only indirectly related to the claimed device.

Kite and surfing are widely known for moving on the water surface. But these devices can most likely be considered as distant analogues of the proposed device. Known devices are quite expensive, require special skills, are unsafe for use by inexperienced people, not to mention the use of their children or those who can not swim. In addition, they are bulky, inconvenient to transport and require at least two people to set sail. Unlike a kite, for example, the Vetwinder inflatable sail does not slam on the water, but lays on the surface of the water and turns into a life-saving tool, on which you can just lie swaying on the waves, like on a swing, but you can swim. Moreover, it has a low cost, since

It is made of inexpensive material, the product weighs about 700 grams, is convenient for transportation, for example, in a deflated condition it is placed in a standard bag. No prior user training is required and can be used by the age group of 6 to 60 years. In addition, it can be used both independently and as a sail for a floating craft (boat, raft, etc.), and also as an awning for relaxing on the shore of a reservoir.

The inflatable sail Vetwinder is installed on the water surface and takes the form of a visor, ready to receive wind. As soon as the wind appears, Vetwinder opens and pulls any attached cargo (person, boat, raft). The speed of movement depends on the wind speed, the weight of the cargo and the size of the sail. If there is no wind at Vetvinder, you can lie down on a mattress and rest.

Figure 1 presents the inflatable sail Vetwinder, where:

1 - arc, 2 - jumper, 3 - sail, 4 - sling;

Figure 2 shows the use of Vetwinder as an awning when resting on the beach;

Figure 4. Testing a prototype Vetwinder on water.

An inflatable sail Vetvinder is two arcs 1 (Figure 1), made in the form of inflatable arc cylindrical elements interconnected by at least three jumpers 2, made in the form of inflatable cylinders of smaller diameter. On the outer side of the arcs and extreme jumpers, sail 3 is made of transparent material. At the ends of the arcs made elements (narrowing, expansion, loop, etc.), allowing to securely fasten the ends of the four lines 4, which are in a certain way combined at a certain distance from the sail.

Claims (5)

1. An inflatable sail, including two arcs made in the form of inflatable arc cylindrical elements interconnected by at least three jumpers made in the form of inflatable cylinders of smaller diameter, the sail is fixed on the outside of the arcs and extreme jumpers, the elements are made at the ends of the arcs, allowing to fix the ends of the slings, in a certain way united at a certain distance from the sail. 2. An inflatable sail according to claim 1, characterized in that a transparent material is used to manufacture the actual sail. 3. The inflatable sail according to claim 1, characterized in that the elements at the ends of the arcs are made in the form of a narrowing. 4. The inflatable sail according to claim 1, characterized in that the elements at the ends of the arcs are made in the form of an extension. 5. The inflatable sail according to claim 1, characterized in that the elements at the ends of the arcs are made in the form of a loop.
