ABOUT

The invention relates to sport, in particular, equipment designed to carry out support jumps thereon.

Known gymnastic horse, containing the base on the uprights, mounted on the base of the supporting element with a coating and means of depreciation placed between the base and the supporting element 1.

However, in the well-known gymnastic horse, when the athlete is on the extreme part of his body, the final support surface of the latter lowers and occupies an inclined position, which is unusual for a gymnast, violates the technique of the jump.

The purpose of the invention is to increase user convenience by allowing parallel movement of the support member.

The goal is achieved by the fact that in a gymnastic horse containing a base on racks, a coated supporting element mounted on a base and a damping means placed between the base and a supporting element, the damping means contains two pairs of levers mounted on a common horizontal axis, each of which is scissors and carries rollers at the ends, the lower of which are connected by a spring, while on the base and the inner side of the support element parallel to the longitudinal axis are mounted the guides, and the bases It has side walls with vertical grooves, the axis of the levers being placed in the grooves of the side walls, and the rollers freely mounted in the guides.

The purpose of adjusting the hisstatic elasticity of the cone is that the spring is located under the base and is made in length in two parts connected by a mechanism for regulating its elasticity.

FIG. 1 shows a gymnastic horse, a general view; in fig. 2 shows section A-A in FIG. one.

The gymnastic horse contains a base 1 on the uprights 2 on which the supporting element 3 with the coating 4 is mounted. Between the base 1 and the supporting element 3 is placed a depreciation means containing two pairs of levers 6 installed on a common horizontal axis 5, each of which is made in the form of scissors and 7. bears rolls on the ends. Lower ends of levers

5 6 are connected by a spring 8, which is located under the base 1 and is made of two parts.

On the base 1 and the inner side of the support element 3, the guides 9 are mounted parallel to the longitudinal axis. The base 1 has side walls 10 with vertical grooves I. The axis 5 of the levers 6 is placed in the slots 11, and the rollers 7 are freely mounted in the guides 9. Parts the springs 8 are connected by a mechanism for regulating its elasticity, consisting of two threaded bushings 12 and 13 with a right and left thread and a screw 14 placed between the bushings. To determine the degree of tension of the spring, the shchal 15 and risk ring 16 on the hub 12 serve.

Training with this design con is carried out as follows.

With the push of the gymnast about any part of the support element 3 lever-spring

the mechanism folds, with the upper

and the lower rollers 7 move in the guides 9 and the springs 8 are stretched, and the axis 5 moves in the grooves 11 of the side walls of the base. With the release of the reference

0 of the load element 3, the lever mechanism is returned to its original position by the action of the spring 8.

To increase the tension of the spring (which is equivalent to an increase in the elasticity of the con), it is enough to turn the screw 14, while

This risk 16 on the sleeve 12 will show on the latch 15 the appropriate degree of elasticity.

The use of this design gymnastic con variable elasticity

will reduce the shock load on the hands of the gymnast during the execution of jumps, reduce injuries gymnasts, as well as increase the intensity of training, and the adjustment of elasticity will enable the gymnast to perform basic jumps on the horse of optimal elasticity.

Claims (2)

1. GYMNASTIC HORSE, containing the base on the uprights, mounted on the base of the coated support element and depreciation means, located between the base and the support element, characterized in that, in order to improve ease of use by providing parallel movement of the support element, the depreciation means comprises a common horizontal axis, two pairs of levers, each of which is made in the form of scissors and carries rollers at the ends, the lower of which are connected by a spring, while on the base and internally side support member parallel to the longitudinal axis of the horse, mounted guides, and the base has side walls with vertical grooves, wherein the axis of levers placed in the grooves of the side walls and the rollers are loosely fitted in the guide. 2.
