Abstract

FIELD: games; sports.

SUBSTANCE: invention provides higher safety and manufacturability of pneumatic roller, unifies and broadens functional capabilities. Summary of technical solution consists in fact that in pneumatic roller consisting of pneumatic chamber ring, equipped on inner surface with rigid circular guides for seats with roller supports, guide is made in form of looped metal pipe, equipped at level of tube diameter with system of trundles pairs, equally spaced from looped tube lengthwise mirror plane, pneumatic chamber ring is made in form of system of pneumatic chambers with internal diameter comparable with looped tube diameter folded in diameter and locked in pairs by flexures at trundles, roller supports are made in form of single-cavity hyperboloids with working surface under looped tube diameter. Cogs are equipped with replaceable telescopic design bushings, cogs for fixation of bending of each pneumatic chamber on right prevent cogs for fixation of bending of each pneumatic chamber on left or cogs for fixation of bending of each pneumatic chamber on right lag behind cogs for fixation of bending of each pneumatic chamber on left.

EFFECT: invention can be used as a gymnastic apparatus for year-round tobogganing.

Description

The invention relates to entertainment and can be used as a sports equipment for year-round skiing from the mountains.

Known pneumatic scooter / see, for example, w / o “Modeller-constructor”, 2011, No. 11, pp. 2-3 /, consisting of a pneumatic chamber ring provided on the inner surface with rigid ring guides for a chair with roller bearings.

A disadvantage of the known device is the poor design study of the safety of riding and the manufacturability of the manufacture of a pneumatic scooter.

Also known pneumatic scooter / cm. US Pat. No. 2525824 (class A63G 17/00) dated 08/09/2013 /.

With all the advantages of the design scheme, the technology for manufacturing pneumatic scooters can be improved in order to unify and expand functionality.

For the technical solution of the stated purpose, in a pneumatic scooter consisting of a pneumatic chamber ring equipped with rigid ring guides for a chair with roller bearings on the inner surface, the guide is made in the form of a looped metal pipe equipped with a system of pairs of spindles equidistant from the longitudinal plane of symmetry of the looped pipe at the level of the pipe diameter , the pneumatic chamber ring is made in the form of a system of pneumatic chambers with an inner diameter commensurate with the diameter of the looped pipe, folded in diameter and fixed in pairs by kinks on the spindles, the roller bearings are made in the form of single-cavity hyperboloid with a working surface for the diameter of the looped tube, the spindles are equipped with replaceable telescopic sleeves, the bend fixing bobbins of each pneumatic chamber on the right prevent the bending bobbin fixing bobbins of each pneumatic chamber on the left or the bend fixing bobbin on the right lag behind the pin of fixation of the inflection of each pneumatic chamber on the left.

The technical solution proposed by the invention is illustrated in the drawing (general view, with pneumatic chambers through 30 ° on the lugs).

The pneumatic scooter consists of a pneumatic chamber ring equipped with rigid ring guides for a chair with roller bearings on the inner surface, where the guide is made in the form of a looped metal pipe 1, equipped with a system of pairs of spindles 2 equidistant from the longitudinal plane of symmetry of the looped pipe 1, pneumatic chamber ring made in the form of a system of pneumatic chambers 3 with an inner diameter commensurate with the diameter of the looped pipe 1, folded in diameter and fixed in pairs bend at two bobbin and roller supports (Fig. not shown) are made in the form of hyperboloid of one sheet with the work surface under the loopback diameter of the tube 1.

At the same time, the yokes 2 are equipped with telescopic sleeves 4, the yokes 2 of the fixation of the inflection of each air chamber 3 on the right are preempted by the yokes 2 of the fixation of the inflection of each air chamber 3 on the left (as in the drawing) or the yokes 2 of the fixation of the inflection of each air chamber 3 on the right are lagged behind the foreshanks 2 of the fixation of the inflection of each air chamber 3 on the left.

A pneumatic chamber ring, made in the form of a system of pneumatic chambers 3, with an inner diameter commensurate with the diameter of the looped pipe 1, having in the assembly alternating (for example, through 30 °) pairwise bends of the pneumatic chamber 3 with the pin 2 of the fixation of the bend of each pneumatic chamber 3 to the right, the preventive pin 2 of the fixation the inflection of each pneumatic chamber 3 on the left (for example, as shown in the drawing by striping in the longitudinal plane) is obtained with the lug effect, expanding the functionality of the pneumatic scooter. For the manufacture of a pneumatic scooter of the proposed design on a looped pipe 1, it will be required: a) 12 pneumatic chambers 3, alternating in the assembly through 30 °; b) 24 pneumatic chambers 3, alternating in the assembly through 15 °; c) 30 pneumatic chambers 3, alternating in the assembly through 12 °.

The technical solution proposed by the invention improves the safety of skiing (since it eliminates the simultaneous puncture of all pneumatic chambers filled with compressed air or gas, the pneumatic chamber ring) and manufacturability of the pneumatic scooter (since restrictions on the diameter of the pneumatic scooter with standardized components are practically eliminated), unifies and expands the functionality of the pneumatic scooter .

Thus, according to the applicant, the proposed technical solution is new, has an inventive step and is industrially applicable both for its intended purpose and in adjacent areas with a pneumatic-wheeled chassis.
