Description

The present invention relates to sports equipment and is intended for effective training of the muscles of the shoulder girdle, press, back and chest, strengthening the joints of the hands and wrists, the development of dexterity, endurance and coordination of movements.

Guides are mandatory elements of almost all open sports grounds for people of any age, as they are considered effective means of increasing the level of a person’s physical condition. The scope of the manuals is extensive: they are used in physical education classes in various secondary and higher educational institutions, kindergartens, military sports towns, etc.

In general, the guides consist of different-sized posts with various stairs placed on them. Guides can be straight, curly and combined.

There are a large number of designs of guides: circular, circular, curved (in the form of a snake, wave or sun) and others. There is a triple (or three-level) guide, which consists of three straight stairs successively placed at a certain height: for lifting a person (ascending), for horizontal movements and for the descent of a person (descending) [1, 2, 3, 4].

These booms are easy to manufacture, but a common drawback when using them is not always a reasonable logical sequence for entering loads on the muscles and joints of a person.

Closest to the proposed invention for technical implementation is the creeper "Cadet" [5]. The prototype is four stairs sequentially connected to each other mounted on vertical posts (supports): horizontal, ascending, descending, horizontal (Fig. 1). When using such a guide, the load on the muscles and joints is introduced in the following sequence: the average intensity load when moving along the first horizontal ladder, then the maximum load when climbing the ascending ladder, then the minimum intensity load when descending the descending ladder, and finally the average again load when moving along the second horizontal ladder. From a medical point of view, this sequence of loads is the most rational.

The disadvantage of the prototype (as well as analogues) is that all the columns have an unchanged height. This, in turn, does not allow changing the angles of inclination of the stairs, i.e. It does not allow you to quickly change the load on the muscles of a person during training.

When it becomes possible to change the height of the supports, the following optimal algorithm for physical training can be implemented: initially, for a physically poorly trained person, the angle of inclination of the ascending ladder must be set to minimum (or zero at all). Further, as he is trained, the angle of inclination of this ladder must be successively increased to some maximum value. Or if at the end of a specific lesson a person is tired, then the angle of inclination of the stairs can again be gradually reduced, etc. All this allows a metered and competent increase in the load on the muscles of a person.

Of course, on the sports ground, you can have several guides with different and constant angles of inclination of the stairs. However, this will require substantial investment and will geographically occupy a large part of the sports field.

The rapid change in the slope of the ladder guides is of great importance during sports training of people, especially - when playing sports for children of young and middle age.

The aim of the invention is to expand the functionality of the guide, which consists in the possibility of a targeted operational change in the angle of inclination of the ascending ladder from zero to some maximum value.

This goal is achieved by the fact that in the Verbovyh guide containing two horizontal ladders installed at its ends on equal supports of constant height, the middle ascending and descending stairs and two central supports are made telescopic, all the stairs are successively connected by six rotary joints, of which the two central ones are supported by telescopic telescopic supports; additional removable crossbars can be installed on telescopic ladder racks m (lowering) of the sliding parts of the telescopic supports is fixed using clamps. All the racks of the stairs and all the vertical supports of the handle can be made of pipes of any (round or rectangular) section, and the crossbars of the stairs, both stationary and removable, are made only round with a diameter convenient for grabbing them with your hands.

The design of the proposed manual and the procedure for its intended use are illustrated in FIG. 2, 3 and 4.

The Verbovs' guide includes (Fig. 2) two horizontal stairs 1 ₁ and 1 ₂ installed at its ends on equal and unchanged vertical supports (for example, let there be eight supports) 2 _1-8 . Two telescopic ladders 3 ₁ and 3 ₂ are located in the middle of the guide (one is ascending to lift a person, and the second is descending to lower it) with retractable racks 4 ₁ and 4 ₂ . These telescopic ladders are connected with each other and with both horizontal ladders using six rotary joints 5 _1-6 . Two central rotary joints rest on the sliding parts 6 ₁ and 6 _{2 of the} two central telescopic supports 7 ₁ and 7 ₂ . On the retractable racks 4 ₁ and 4 _{2, it is} possible to install additional removable rails 8 (when the racks are extended from the stairs) or to remove them (when the retractable racks enter the stairs). The lifting (lowering) of the sliding parts of the supports is fixed using the corresponding clips 9 ₁ and 9 ₂ .

In FIG. 3 a) and b) one of the options for installing removable crossbars on the sliding parts of telescopic ladders is shown, and in FIG. Figure 4 shows a side view of the Verbovy grip when using it.

To use the proposed manual can be as follows.

At the initial stage of training, the retractable parts of the telescopic supports 7 ₁ and 7 ₂ are in the lowest position, i.e. all four stairs are horizontal. A novice athlete learns to move on his hands along these horizontal stairs with minimal loads. After the trainee moves confidently and effortlessly along horizontal stairs, the trainer or the trainee himself can slightly raise the sliding parts of the central telescopic supports and fix in this position with the clamps 9 ₁ and 9 ₂ . In this case, the retractable racks 4 ₁ and 4 _{2 of the} telescopic ladders 3 ₁ and 3 ₂ will be slightly extended. Since there are no crossbars on the sliding parts of the telescopic stairs, additional removable crossbars 8 are installed on them (as shown in Fig. 2).

After that, the athlete begins to train with a small angle of inclination of the ascending ladder. In this case, the load on the muscles and joints of the athlete will be slightly increased when he moves along this ladder. After the trainee confidently and effortlessly moves up the ladder with a small angle of inclination, the trainer or the trainee himself can raise the telescopic supports even further and also lock in this position. On the extended racks of the telescopic ladders, additional removable crossbars are installed 8. After that, the lever is again ready for athlete training, but with a large angle of inclination of the ascending ladder.

Further, the use of the handle is similar up to the maximum angle of inclination of the stairs (Fig. 4).

In FIG. Figure 3 shows a possible simplest option for installing removable crossbars. Each crossbar has two pins that are inserted into the corresponding holes in the telescopic ladder retractable racks. The length of the pins, obviously, will depend on the angle of the stairs: the larger the angle, the longer the pins must be, so that the crossbar does not spontaneously pop out of the hole when the person is on the handle. For reliable mounting, the holes in the uprights can be through, and the length of the pins should be slightly longer than the diameter of the pipe (not shown in Fig. 3). This option to install the crossbars is not only easy to implement, but it also allows you to quickly install (remove) the crossbars in a minimum time. There are other options for installing (removing) removable crossbars.

To raise or lower the sliding parts of the telescopic supports 7 ₁ and 7 _2, you can use various technical devices, such as hydraulic or mechanical. However, they will significantly complicate the design of the handle, increase its cost, complicate its operation and maintenance. The easiest way is to increase the height of the telescopic supports manually (even to a few people) with the subsequent fixation of the sliding parts in the desired position by the known simplest mechanical stopper, which is not considered in the description, due to the simplicity of such fixing.

Thus, the advantages of the proposed Verkhov guides are:

1. Great functionality, which is manifested in the ability to quickly, without much effort, purposefully change the angle of inclination of his ascending ladder from zero to some maximum value, which will allow the athlete to smoothly and metered increase physical activity.

2. The simplicity of technical implementation, operation and maintenance.

3. The possibility of manufacturing from improvised cheap material.

4. Minimum economic costs for its manufacture.

5. The use of detachable swivel joints 5 _1-6 will allow the creation of portable guides, which will further expand their functionality and increase ease of use.

The use of the Verbovs guide will allow everyone to strengthen their physical fitness consistently, without unhealthy overloads.
