Description

The utility model relates to circus equipment, in particular to auxiliary devices for artists, and can be used for circus performances when performing circus tricks using drum-shaped wheels fixed to the end sections of a two-link working boom.

 A reference boom of a circus acrobatic device is known, containing the main and counterweight links, between which the central support suspension with bearing assemblies is located, the main impeller of the drum form is fixed at the end of the main link, and the counterweight is fixed at the end of the counterweight link (see, for example, RF patent for Utility Model No. 184091 according to IPC A63J 7/00, published on October 15, 2018, as well as https://www.youtube.com/watch?v=ieJt8vj7kKc).

The closest in technical essence is the supporting arrow of a circus acrobatic device containing the main and counterweight links, between which the central supporting suspension with bearing assemblies is located, the main impeller of the drum form is fixed at the end of the main link, and the drum form counterweight is fixed at the end of the counterweight link (see ., RF patent for utility model No. 184091 according to IPC A63J 7/00, published on October 15, 2018).

A disadvantage of the known support boom is the limited number of functional and operational capabilities, since acrobatic stunts can be performed by only one acrobat, since the support boom is made with one impeller, which reduces the entertainment of performances.

The technical result is the expansion of functional and operational capabilities with an expanded range of performed tricks, increasing the entertainment of performances.

The technical result is achieved by the fact that in the supporting boom of a circus acrobatic device containing the main and counterweight links, between which the central supporting suspension for the bearing assemblies is located, the main impeller of the drum shape is fixed at the end of the main link, and the counterweight is fixed at the end of the counterweight, according to the useful the end section of the counterweight link is equipped with an additional drum-shaped impeller, inside of which a counterweight is installed in the form of a protrusion segment vovesnogo link, the main link is provided with additional support for the suspension of bearing assemblies disposed between the central support for bearing the suspension assemblies and the main impeller and the counterweight balancing unit is provided with lateral plates, disposed between the central support and suspension additional impeller. The supporting boom is made of a collapsible design with flange connections. The supporting boom is made with a lattice-frame structure. The link of the counterweight segment is made with a counterweight ring weighting agent.

The essence of the utility model is illustrated by schematic drawings.

In FIG. 1 shows a support boom assembly; in FIG. 2 - supporting boom assembly, designed for experienced artists; in FIG. 3 - supporting boom assembly, designed for small rooms and for training; in FIG. 4 - the main link; in FIG. 5 - counterweight link; in FIG. 6 - a segment of the counterweight link.

The supporting arrow of the circus acrobatic device contains the main 1 and counterweight 2 links, between which the central supporting suspension 3 for bearing assemblies is located. At the end of the main link 1 is fixed to the main impeller 4 of a drum shape.

 The reference boom is equipped with an additional impeller 5 of a drum shape fixed to the end portion of the counterweight link 2.

Inside the additional impeller 5, a counterweight is installed in the form of a segment of a counterweight link 6, at the end of which a counterbalanced ring weighting agent 7 is fixed.

The main link 1 is equipped with an additional support suspension 8 for bearing assemblies located between the central support suspension 3 and the main impeller 4.

The support boom is made of a collapsible design with flange connections 9, 10, 11 and 12. The counterweight link on both sides is provided with side balancing plates 13 located between the central support suspension 3 and the additional impeller 5. The support suspensions are made with support plates for mounting the axles bearing units mounted on both sides on the sides of the boom.

The use of the proposed reference boom is as follows.

In the initial position, the supporting arrow of the circus acrobatic device is disassembled at the prepared stage for performances.

If the platform for performances is adapted for the use of performances of large-sized circus acrobatic devices, then when assembling the support boom all links and segments are used, including the main impeller 4, the additional impeller 5, and also a counterweight in the form of a counterweight link segment 6. This design of the support boom It is used due to the lack of experienced acrobats and a group of acrobats takes part in the performance, each participating in the performance with their own special tricks.

If experienced acrobats participate in the performance, then when assembling the counterweight link 2, the segment of the counterweight link 6 in the additional impeller 5 is not used in the assembly.

Four experienced acrobats can participate in the performance, who perform complex stunts simultaneously on the main impeller 4 and the additional impeller 5.

If the platform for performances located in a room unsuitable for using large-sized circus acrobatic devices or in open areas, then during assembly only the main link 1 and the counterweight segment 6 are connected, interconnected by means of a flange connection 10. This design can be used as in representations, and for training novice artists who want to participate in circus performances.

Acrobatic stunts, as well as in the known analogues, are performed on a freely rotating support arrow, the rotation of which is carried out by moving the acrobat on the surface of the impeller, while changing the speed of rotation to perform the corresponding acrobatic stunts.

The proposed reference arrow of a circus acrobatic device with enhanced functional and operational capabilities allows you to adapt the circus acrobatic device to specific new conditions, which can vary and depend on the state of the artists, as well as on the condition and size of the rooms offered for performances.

The design of the device expands the functional and operational capabilities with an increase in the variety of tricks and increased entertainment performance.

Testing prototypes of the device showed high reliability and safety of the design.
