Description

The invention relates to sports equipment, gymnastic and athletic equipment, toys, massagers and can be used for physical exercises to develop and strengthen various muscles of the body, combined with simultaneous massage, for sports competitions as an athletic and gymnastic projectile and for entertainment.

The purpose of the invention is to create an inexpensive, universally available universal sports simulator, an athletic and gymnastic apparatus, a toy, a massager, and a more effective hoop in one subject.

There are a huge number of sports simulators designed to develop and strengthen the muscles of the human body.

Known trainers are expanders for strengthening the muscles of the arms, chest and back, working to compress the spring or working body, known trainers-expanders working on stretching the spring or elastic element (We 2123369, VI 2111036, 8I 1797493).

Known simulators to strengthen the hands, creating a load during the torsion of any handles (8I 1516131).

Known universal and combined simulators designed to strengthen and develop a large part of the muscles of the human body, which are bulky, complex, expensive machines, equipped with a huge number of devices to adjust to various exercises (VI 20508881, VI 2105582).

Known gymnastic and massage hoops designed to strengthen the spine and massage the body of a person, creating a load during rotation around the body, as well as being the subject of children's entertainment (8I 18014458, И8Л 40529882, 8И 14073770).

Known massagers and massage tools designed to massage various parts of the body, by physical exposure to an elastic object of various shapes.

There are various objects for throwing - rings, disks, nuclei, etc. (VI 2033829, Egaise 2468389).

Famous sports equipment and toy ball. The ball has an ideal geometric shape of the ball. There are also other sports equipment with an ideal geometric shape of the ball - the core, bowling balls. The ball differs in that it is made of thin elastic material, it has increased pressure inside, and because of this it has a high springiness. It is because of this property that the ball, like a sports equipment and a toy, has received the widest distribution in the world in comparison with any other object. On the application of the ball built the most popular game sports: football, basketball, volleyball, tennis, golf, etc.

But there is a second ideal geometric form - the torus. As well as a ball, a torus has non-inflatable analogues of sports equipment - these are different types of hoops, gymnastics, children’s and massage, throwing rings, etc. All these shells are significantly higher in their properties than non-inflatable ball analogues: cores, bowling balls, etc.

There are toroid-shaped objects made of elastic material, fitted with a valve for increasing pressure - these are automobile and bicycle chambers, inflatable rescue vehicles, as well as children's circles for learning to swim. But as a universal simulator, a sports projectile, a hoop, these items are not used and cannot be used as an analogue.

Also known gymnastic hoop, used as a sports apparatus for practicing rhythmic gymnastics and for rotation at the waist.

The closest in form and content of the present invention is the playing ring for the German patent 24 41 24 998 A1, АВВ 19/00, dated 07.27.91. The game ring has a diameter greater than the diameter of the swimming circle (approximately more than 80 cm, up to 130 cm), made of a soft plastic hose (for example, PVC), having a cross section of 10 to 20 cm, equipped with a nipple for inflating and descending air. Children can run through a rolling ring, catch a player’s partner without danger of injury, play in a space bounded by a playing ring.

Gym properties above game ring does not imply. Soft PVC hose is not designed for high pressure, to provide the necessary rigidity, a large cross section in excess of 10 cm is placed in the ring, which is inconvenient for brushing.

To increase the effect on the waist when rotating around the torso, as well as giving the hoop universal training properties, we offer an inflatable hoop-top made of elastic material, equipped with durable and flexible reinforcement, having a toroidal sealed cavity, equipped with a valve that does not protrude pressure; at the same time, the top shell has a cross-section diameter of 3-8 cm and is capable of withstanding numerous bends and deformations, including impact ones, at a pressure of at least 3 atm.

Since the inflatable hoop - top is proposed to be used as a universal simulator, and the effort when doing the exercises is mainly applied with the hands directly to the top itself, it should have a cross section that is convenient for reaching the child’s or adult’s hand. Convenient diameter ranges from 3 to 8 cm.

The force of compression or bending of the inflatable hoop is created due to the air pressure in the cavity, the higher the pressure, the greater the force. The minimum effort at which children and physically weak women can engage in an inflatable hoop is 1.5-2 atm., But at least a two-fold safety margin is necessary, that is, an inflatable hoop-top must withstand a pressure of at least 3 atm.

Since the pressure is over 3 atm. is rather high, for comparison, in an inflatable circle the pressure does not exceed 0.5 atm., in a rubber ball 0.7-1 atm., the pressure must be maintained not due to the strength of the material, but due to durable reinforcement, in order for the inflatable the hoop was safe and could not explode. Therefore, the material from which the inflatable hoop-top is made must necessarily have flexible and durable fittings.

FIG. 1 - inflatable hoop - top, slit;

FIG. 2-7 - various types of exercises with top.

FIG. 1: the inflatable hoop-top contains a tubular sheath 1, closed in a ring of large diameter and made of durable elastic reinforced material, forming a sealed toroidal cavity 2 into which increased pressure is pumped through valve 3.

FIG. 2: when compressing a top 1 made of elastic material and containing increased pressure, top 1 tends to return to its original position and again take on a round shape. The arrows indicate the effort that must be applied by hand in order to squeeze the top into the shape of the eight.

FIG. 3: The arrows indicate the force to stretch the top into an ellipse.

FIG. 4: top 1 rests on any part of the human body 4: abdomen, chest, back from the buttocks to the shoulder blades, shoulders, neck, legs, and the force of the hands, shown by arrows, is brought into the depicted position. This exercise is combined with an effective massage of the corresponding part of the body with an elastic object.

FIG. 5: the top 1 is overtightened by a belt 5 up to the figure of eight and hands can be applied to it, shown by arrows, by twisting in different directions.

FIG. 6: the top 1, tightened by a belt 5, is pressed down by some part of the body 4 and is bent by the force of the arms.

FIG. 7: Top 1, strapped by a belt 5, is bent by the force of arms or legs. It will be easy to develop a wider range of exercises and get a load and massage effect on almost all parts of the human body.

The inflatable hoop-top corresponds to the purpose: a universal simulator and a massager.

The top, made of elastic material and containing increased pressure in the cavity, has a very high springiness. You can throw it, hit it on the ground, throw it on a peg, shoot down targets and so on. The top can be twisted around the waist, like a regular hoop and perform various gymnastic exercises with it. Tops can be compressed to measure strength.

When the inflatable hoop rotates around the torso, the elastic ring bends under the impact of shocks imparted to it by the body, and thus absorbs some of the energy that is expended on the rotation. Because of this, a person who rotates an inflatable hoop spends much more energy on maintaining rotation in comparison with a regular hard hoop and thus gets a more effective effect on the waist.

The inflatable hoop-top corresponds to its purpose: athletic, gymnastic equipment and toys.
