Gymflextor Training Device

Abstract

The invention relates to gymnastic and exercise equipment and can be used for physical exercises to develop and strengthen body muscles, for carrying out sports events and in leisure activities. Said invention makes it possible to increase the durability of the training device, the elasticity of the surface thereof and to extend the possibilities for modifying the shape of training device as a result of its structure, comprising a pressurized torus-shaped sealed reinforced chamber which is provided with a flush-mounted valve and means for modifying the shape of the chamber. Said reinforced chamber consists of an internal hermetic chamber and multilayer textile reinforcement, located on screw line around hermetic internal chamber, wherein the coils of the textile reinforcement of adjacent layers are oppositely oriented with angle between coils of 30 to 150°, and of an outer sheath made of an elastic cloth.

AI Technical Summary

Benefits of technology

[0009] Construction of the training device made of hermetic inner chamber, non-airtight layers of textile reinforcement and nonhermetic outer sheath increase its operational safety, because in case of defects in the inner shell, air will pass through the layer of reinforcement and outer sheath without causing damage to the user. Besides, if air leakage is not significant, the training device could be used under the condition of periodic inflation through the flush-mounted valve.

[0010] The training device it is repeatedly exposed to bending when in use. Arrangement of reinforcement in coils oriented oppositely in different layers, promotes reduction of residual memory at deformations of the device and helps to return the device to initial state. The number of reinforcement layers should not be less than two, and the upper limit on the number of layers is determined by durability, thickness and density of material of which reinforcement is made. It is experimentally determined that the angle between coils should be in the range of 30 to 150 degrees, providing for the minimal deformations to the shape of the device. Outer sheath made of elastic fabric or porous elastic material reduces mechanical impact of the device on the body of the user, covers layer of armature and can be decorated in manufacturing, which can be important for creation of upbeat mood during exercise.

[0011] Device designed to change the shape of the training device allows it to stay bent for a long time, promoting deformations due to non-uniform stretching of textile armature, which can change the torus shape of the device. In order to avoid such deformations, additional strengthening is stipulated in design of device in the form of strong textile lining hav...

Problems solved by technology

The known device made from reinforced material, has inadequate strength, which is connected with insufficient coherence of elastic material with armature, coursed by difference in physical-mechanical properties of materials.

Under pressure inside the chamber within the limits of 8-10 atmospheres and alternating loads, forming of defects of internal surface of the chamber, ...
