Abstract

The invention improves the performance properties of the mat by reducing the rebound of the athlete upon landing. The goal is achieved by introducing an air-permeable layer 7 located between the bottom layer of the elastic-elastic filler 5 and the bottom part of the cover 3. The hollow chambers 6 are connected to the layer 7 by the holes 8. The side walls of the cover 3 have holes 4 for communication with the atmosphere. Above the upper layers of the filler 5 there is a working carpet 1, laminated with foam material 2. When the athlete lands at the initial moment when the loads are small, the mat works like a spring. With increasing load, the air from the chambers 6 begins to escape through the holes 8, the layer 7 and the holes 4 to the atmosphere. The remaining layers continue to work as a spring. By reducing the load, the damping layer recovers much more slowly than other layers of the filler. 1 il.

elastic filler 5 and the bottom of the cover 3. Hollow chamber δ connected with a layer of 7 holes 8. The side walls of the cover 3 have holes 4 for communication with the atmosphere. Above the upper layers of filler 5 is a working carpet 1, laminated with foam 2. When the athlete lands at the initial moment when the loads are low, the mat works like a spring. When the load increases, air from the chambers 6 begins to escape through openings 8, layer 7 and openings 4 into the atmosphere. The remaining layers continue to work like a spring. When the load is reduced, the damping layer is restored much more slowly than other layers of the filler. 1 ill.

The invention relates to sports, in particular to gymnastic apparatus.

The aim of the invention is to improve operational properties by reducing rebound.

The drawing shows a gymnastic mat, cross section.

The gymnastic mat contains a working carpet 1, laminated with foam 2, closed at the bottom and sides with a fabric cover 3 with holes 4 on the side walls for communication with the atmosphere. In the case> 5, layers of elastic resilient filler 5 are placed with the formation of air cavities - hollow chambers 6. Between the lower layer of the filler and the bottom of the case 3 there is a 20 layer of breathable material .. Hollow chambers 6 communicate with layer 7 through there are holes 8 in it.

Mat works as follows. 25 The athlete’s foot effort is transferred to the working carpet 1, which redistributes it to an area larger than the feet foot area, and transfers 2 jq and filler 5 to the foam layer. At the initial time, when the loads are relatively low, the whole system works like a spring . When the load increases, air from the hollow chambers 6 begins to escape through the openings 8 through a layer of breathable material 7, which prevents the openings 8 from being covered with a fabric cover 3, the cover into the atmosphere.

and through the holes the remaining layers of material continue to work like springs. This process occurs up to the maximum implementation of the athlete's feet in the mat. Then the load on the mat is gradually reduced. The layers of the foam material of the 2nd filler 5 return to their initial unstressed state. The damping layer is restored much more slowly when the load is removed and returns to its original state when the mat is completely unloaded (taking into account the free-standing athlete).

Using the proposed mat eliminates the possibility of injury and provides the necessary aesthetics when performing exercises and jumps from the shells.

Claims (1)

Claim A gymnastic mat containing an elastic-elastic filler placed in a cover of several layers with the formation of air cavities between them and a carpet, characterized in that, in order to improve operational properties by reducing rebound, it is equipped with a layer of breathable material located between the bottom of the cover and the lower layer filler, while in the lower layer of the filler and the sides of the cover holes are made for communication of air cavities with the atmosphere.
