Abstract

It should be developed a buoyancy aid, which leads to impact on the body of the learner to no injuries and their buoyancy force is variable. This buoyancy aid with handle for making the body contact and unsinkbar buoyancy body contains a buoyancy body of slightly gewoelbten and self-contained unsinkable segments, of which at least two segments in the surface of a shock-absorbing material and the buoyancy of the buoyancy body of the amount of force and / or the point of application of the force on the body is adjustable.

Title of the invention Floating aid Field of application of the invention

The invention relates to a buoyancy aid, in particular for children, in learning to scarf and to carry out group therapies.

Characteristic of the known technical solutions

Various swimming aids are known, which are held by the swimming learners with his hands. The well-known swimming board is unwieldy and uncomfortable to hold on. There is a risk that when you release the swimming board jumped out of the water and hurt the learner.

To avoid this defect, a buoyancy aid is known with at least one handle for plaguing the same and with at least one buoyant body, each passing through a buoyancy support rod, which protrudes from him at least hand width (DE-OS 2918155) ·

η ι

A disadvantage of this buoyancy aid is that the risk of injury when releasing the buoyancy aid is still given.

A further disadvantage is that the buoyancy of the buoyancy aid is not adjustable according to the conditions of the learning process.

Object of the invention

The object of the invention is a buoyancy aid with a low injury factor and a buoyancy force adjustable according to the conditions of the learner.

Explanation of the essence of the invention

The object of the invention is to develop a buoyancy aid, which leads to injury to the body of the learner to no injuries and their buoyancy force is variably adjustable.

This object is achieved by a buoyancy aid with handle for Herateilen, body contact and unsinkable buoyancy of foamed plastic material, according to the invention the buoyancy body of slightly curved and self-contained unsinkable segments is constructed with a radius of curvature of 250 to 600 mm, of which at least two segments In the area of the surface of a shock-absorbing material with closed-cell structure and the buoyancy of the buoyancy body of the amount of force and / or the point of application of the force on the body by attaching the handle on the shell of the buoyancy aid or on the segments of the buoyancy body is adjustable. Advantageously, the segments of the buoyant body are arranged in a shell.

Advantageously, the handles for making the body contact are attached to the shell.

In certain applications, it is convenient to attach the handles for making the body contact to the segments of the buoyant body.

Exemplary embodiments Example 1

From a polyethylene foam with a density of 0.1 and a closed-cell structure, segments of dimensions 20 χ 40 cm are worked out »The thickness of the segments is 6 mm, the radius of curvature is 450 mm« The segments are inserted into a prepared envelope made of a tear-resistant textile material and the sheath closed · The hull is fitted with cross loops on which the learner can hold on. In this form, the buoyancy aid is used by the learner to train footwork. "At the advanced stage of the learning process, the number of segments that are grouped together as a buoyant body must be reduced according to the skills of the learner.

In cases where it is necessary to increase the buoyant force of the learner's body, segments in the area of the back or the abdomen are attached according to necessity.

Example 2

From a foam of a mixture of 60 % polyethylene and 40 % ethylene-vinyl acetate copolymer having a vinyl acetate content of 5 % and a closed-cell structure, 5-cornered segments with the main dimensions 30 × 50 cm are worked out. The foam has an average density of 0.09 g / cm ^, inside a density of 0.07 g / cm3, in the Randbereicben a density of 1.3 g / cm3, the thickness is 7 mm and the radius of curvature 260 mm · The segments are perforated and at the edges by Eyelets reinforced · The segments are inserted into a cover made of tear-resistant textile material and the cover is closed · Loops are attached to the cover, which hold the learner in place · Segments can form segments in the advanced stage of swimming learning

be removed from the shell. Iat it, however, necessary to lifting up the lifting force dea body of the learner, additional segments can be attached to the body by belts, _t are pulled through the holes in the segments.
