FR2640881A1 - Teaching and safety belts for swimming made from deformable composite materials providing a buoyancy aid - Google Patents

Abstract

The invention relates to a device making it possible to float on water, either in a teaching context or in play, by preventing the problems connected with inflatable objects, particularly premature wear and accidental perforation caused by impact. The invention is decisive in terms of the reduction in installation time. It consists of a polyethylene-foam volume of rectangular base, in which a rigid, deformable, steel core F is embedded. Its rigidity is given by a shape which enables it to adapt itself immediately to the required part of the body by simple coiling. The length depends on the desired use. Definitive safety is achieved by the supply of a rapid coupling heat-welded onto the volume Y.

Description

DESCRIPTION
The present invention relates to educational and safety belts for swimming and nautical activities, in deformable multimaterials allowing buoyancy aid.
During swimming sessions organized in an educational framework, polyethylene foam float blocks are used which are connected to each other in a belt. These are used to help the pupils' flotation. In this framework 1k, b installation time is important. On the other hand, the installation of these belts is made difficult because of the different sizes of the students. The time devoted to this installation is lost on the session itself. Other floatation aid systems exist in the form of 'inflatable objects (bracelets or buoys made of heat-sealed plastic). Here too, the time lost is important with regard to inflation and installation in the body. If we add that these inflatable objects exhibit the defect of early wear due to improper use or too repeated, they can also easily be punctured. by shock or bite (for young children).

 The invention defined below makes it possible to make the time taken to use the foam blocks negligible, but also to make the possibility of puncturing inflatable objects obsolete.

 The device according to the invention is made from a volume of polyethylene foam (Figure 1 - reverse; Figure 2 - place; Figure 3 - by volume), the density of which is approximately k 44, in which a deformable stainless steel core is inserted and embedded (Figure 3 and Figure 4 - nomenclature F).

The characteristic of this steel is NS 21 A from UGINE ACIER.

The foam forms, thus produced, original and adapted to the chosen use, are thus placed directly on the desired part of the body (Figure 5), arms, belt, legs, and bvées by simple tightening See the example of the arm in section in Figure 6
The final attachment is done using a system. rapid trademark "Velcro". This system is heat-welded to the volume defined above (Figure 1, Figure 2, Figure 3, nomenclature Y).

 All this in a fraction of a second The disadvantage of bursting through perforation no longer exists, since the object is full.

 The floating object thus defined, on the other hand, can serve as an aid for perfecting swimming, as a flap board or simply as a nautical object with a fun vocation.

 The scope of the invention is immense.

- Importance of the education system (sports and school) for swimming
- Reduction of the school swimming learning sequences in real time, due to the saturation of the pools.

 - Increase in water safety problems linked to the public's enthusiasm for nautical activities, and consequently, search for the reliability of safety equipment.

 - Finally, this invention is maintenance-free, easily accommodated, easily transportable.

Claims (1)
