DE2900681A1 - Wind driven hand held sails - are used for forward movements of ice and roller skaters and are made from pipe frame supporting sails of sail cloth or PVC foils - Google Patents

Abstract

The wind driven hand held sail consists of sail cloth stretched over two main spars as well as transverse rod. The sail is held in the user's hand and is driven forwards by the wind. The cut of the sail and its frame is prod. so that when a change of direction is necessary the position of the sail can be adjusted while the forward movement in the new direction can be continued. The pipe frame and the holding grips are shaped so that both arms are subjected to equal loads, also after a change in the direction of movement. The sail made from light materials such as sail cloth or PVC foil can be attached to the pipe frame without the use of special tools.

Description

Norbert Black

Theenhausener Str. 28 4806 Werther Reinhard Kerker Schelpmilser Weg 60 4800 Bielefeld 1 hand sail driven by wind.

The invention relates to a hand-held sail, which as sports equipment for locomotion through wind, on squares and paths with Roller skates or the like, for moving on ice surfaces with ice skates or the like, for moving on snow surfaces with skis or the like. Is achieved.

In particular, a hand sail for universal use when moving by light or strong wind.

The hand sail is held in place by a tubular frame.

The frame should be designed so that it takes the propulsive forces on brings both arms or transfers them to a shoulder strap. By a special one Section of the sail and a special arrangement of the frame is when the direction of travel is changed just to turn the sail.

The purpose of the invention is to provide an easy-to-use piece of sports equipment for all ages and everyone in different sizes, easy to assemble and versatile in use to construct that for children and adults suitable is.

The state of the art for means of locomotion of the conventional type Wind is on a base with wheels for beach sailors or runners for ice sailors or on a board standing sail, welshes over a mast a fixed resp.

a fixed open bracket between the sail and the underframe. For children to play, these vehicles are practically useless because you Construction is quite complicated. At the same time, these make large and heavy vehicles on busy beaches and ice surfaces represent a not inconsiderable risk of accidents. Also the transport and storage of the devices are a disadvantage.

The discovery has made itself the issue, a hand sail through wind driven, as described at the beginning, to create, which in the structure, in the handling and leadership can be easily mastered even by children. The weight, the packaging as well as the transport should be light, handy and small.

The aforementioned object was achieved according to the invention as described in Claim 1 + 4 described that a specially cut sail (3) with a few simple steps is attached to a tubular frame (la, ib and 2) and is ready for use. With correct The propulsion is generated at the angle of the wind. The simplicity of the sail and frame an inexpensive production is guaranteed.

With the form of training according to claim 2 and 3 one achieves a balanced one Distribution of the propulsive forces to both arms even after a change of direction of travel with sail rotation.

The correct arrangement of the pipes (1a, 1b u. 2), which in a certain Position to the sail area are crucial for easy handling of the hand sail.

With the form of training according to claim 5 is a simplification of different sail sizes to a tubular frame, for tall and heavy people or Reached for small and light people or in weak or strong winds. So a sail can be adapted for different conditions.

With the embodiment of claim 6 is a connection between Body and hand sail, whereby the arms are relieved as the propulsion is brought to the body via the connecting belt. The lanyard should be in can be attached to an open hook in order to quickly disconnect in dangerous situations between the hand sail and the body.

With the embodiment according to claim 7, an optimally shaped one is achieved Sail, which consists of solid material over the entire sail area and one brings very good propulsion effect with a streamlined shape. As a material could you use PVC, GRP, Al or the like. Lightweight materials, which in connection with init a tubular frame or are designed with handles.

With the form of training according to claim 8 and 9, an additional one Relief of the arms through a fixed open connection to the shoe or through a Role of the runner (4a, 4b) supported on the tubular frame of the hand sail to the solid ground.

With the form of training according to claims 10 and 11, there is an improvement the propulsion through special profiling of the sail through pre-formed sail battens or by a headsail, double sail or the like.

The advantages that can be achieved overall with the invention are above all in the fact that the handset, driven by the wind, can be used for many purposes, easy-to-use sports equipment was invented.
