Abstract

FIELD: sport.

SUBSTANCE: invention relates to entertainment and may be used as a gymnastic apparatus for skating onto various flat mainly surfaces. Engineering solution consists in that in circular roller consisting of rigid ring with tread with installed inside carriage provided with roller supports, and steering elements for hands made in form of a rigid frame, ring with tread is composed of rim with pneumatic tyre, load-bearing carriage and steering elements are mounted at corners of two adjacent to ring triangular frames connected by three pairs of shafts, on inner of which there are roller supports under rim on outer of which friction rollers are mounted in form of single-cavity hyperboloids under pneumatic tyre, symmetrically to ring on bottom external shafts are mounted additionally support wheels or pulleys with covering tracks. At least one of three friction rollers in form of single-cavity hyperboloids serves as drive rim with pneumatic tyre.

EFFECT: higher manufacturability of ring roller.

Description

The invention relates to entertainment and can be used as a sports equipment for riding on various flat mainly surfaces.

Known ring scooter / cm. author testimonial. No. 1731038 (class A63G 17/00) dated 04/19/1990 /, consisting of a rigid ring with a carriage mounted on its inner surface, equipped with a foot pad and roller bearings in contact with the surface of the rigid ring by means of rollers in the form of a one-cavity hyperboloid, and the steering element for hands, made in the form of two rigid arcs, convex sides outward in a plane perpendicular to the plane of the ring, and connected rigidly with the lower ends to the carriage, and the upper to the roller support.

A disadvantage of the known ring roller is a poor design study of the manufacturability of the manufacture of a ring roller.

The aim of the invention is to increase the manufacturability of the manufacture of a ring roller.

The stated goal is achieved by the fact that in a ring scooter consisting of a rigid ring having a tread with a load carriage mounted inside and equipped with roller bearings, and a steering element for hands made in the form of a rigid frame, the ring with a tread is made in the form of a rim with a pneumatic tire, carrying the carriage and steering elements are mounted in the corners of two triangular frames adjacent to the ring, connected by three pairs of shafts, on the inside of which roller bearings are mounted under the rim, on the outer of which are mounted ovany friction rollers in the form of a hyperboloid of one sheet of tires, symmetrically on the lower outer ring shaft further mounted bearings or pulleys pnevmokolesa covering tracks.

At the same time, at least one of the three friction rollers drives the rim with a pneumatic tire.

The technical solution proposed by the invention is illustrated in the drawing.

The annular roller according to the invention consists of a rigid ring 1 with a tread with a load carriage mounted inside (not shown), equipped with roller bearings 2, and a steering element for hands made in the form of a rigid frame 3. The ring 1 with a tread is made in the form of a rim with a pneumatic tire, the load-bearing carriage and steering elements are mounted in the corners of two triangular frames 3 adjacent to the ring, connected by three pairs of shafts, on the inside of which roller bearings 2 are mounted under the rim, on the external of which are mounted friction rollers 4 in the form of single-cavity hyperboloids for a pneumatic tire are mounted, symmetrically to ring 1 on the lower external shafts additionally mounted supporting pneumatic wheels 5 (as in the drawing) or pulleys with female tracks.

At the same time, at least one of the three friction rollers 4 in the form of single-cavity hyperboloids serves as a drive for the rim with a pneumatic tire.

The load-bearing carriage in the proposed ring roller can be mounted on roller bearings 2 inside the rim with a pneumatic tire (by analogy with the prototype) or on frames 3 adjacent to the ring, which increases the manufacturability and extends the functionality of using ring rollers.

The nodes and assemblies of the proposed ring roller can be made in the form of structurally complete modules that are easily replaceable in operating conditions.

The technical solution proposed by the invention improves the manufacturability of the production of an annular roller, since the roller is assembled from technologically advanced assemblies, including assembling a stepless rim with an air tire of an acceptable size.

Thus, according to the applicant, the proposed technical solution is new, has an inventive step and is industrially applicable.

Claims (2)

1. An annular roller, consisting of a rigid ring having a tread with a load-bearing carriage mounted inside, equipped with roller bearings under the rim, and a steering element for hands made in the form of a rigid frame, characterized in that the ring with the tread is made in the form of a rim with a pneumatic tire, the load-bearing carriage and steering elements are mounted in the corners of two triangular frames adjacent to the ring, connected by three pairs of shafts, on the inner of which roller bearings are mounted under the rim, on the outer of which are mounted Friction rollers in the form of one-sheeted hyperboloids for a pneumatic tire, symmetrically to the ring on the lower external shafts, additionally mounted pneumatic wheel supports or pulleys with covering tracks. 2. The annular roller according to claim 1, characterized in that at least one of the three friction rollers drives the rim with a pneumatic tire.
