Description

The field of technology.

The invention relates to wheels of folding bicycles with airless tires.

The level of technology.

Bicycle disc wheels are known, consisting of a hub, a disc with a rim, on which a camera and a tire, or a tubeless tire, are mounted. Recently, airless tires have been used, for example, by Nexo, which do not require air injection and hold the elasticity necessary for a smooth movement of a bicycle due to their internal structure. Most often, disc wheels are mounted on road bikes with a standard wheel size of 26 inches or more, including full-size folding bikes.

Folding bicycles, which have recently become widespread among consumers, due to the possibility of compact storage and transportation, depending on the diameter of the wheels, are divided into three categories:

1. Folding bicycles with wheels with a diameter of less than 16 inches, the main characteristic of which is compactness when using complex folding mechanisms, but due to the small diameter of the wheels on such bicycles it is difficult to ride long distances due to the low speed, the handling is also deteriorated. The result is low driving characteristics and comfort.

2. Folding bicycles with wheels from 16 to 24 inches in diameter with complex folding mechanisms. They are a compromise between the desire of the consumer to get a compact bike and its road qualities. Standard wheels with a diameter of 20 inches are considered as the limit for the effective overcoming of obstacles during city driving, such as curbs, speed bumps, pits and the like.

3. Full-size folding bikes with wheel diameters for standard road bikes (26 inches or more), often with one frame hinge, which folds the frame in half. By obtaining full-sized bicycle wheels, such bikes have unlimited road characteristics, but do not differ in compactness, since the dimensions of a folded bicycle are determined by the diameter of the wheels and the dimensions cannot be reduced without removing the wheels in any way.

The aim of the present invention is to provide a collapsible wheel for a full-size folding bike with a wheel diameter of 26 inches or more, which can be disassembled without removing the wheel from the bike, thereby significantly reducing the dimensions of the bike when folded. Thus, the unlimited road characteristics of the road bike will be complemented by compactness when folded.

Disclosure of the invention.

This goal is achieved by the fact that the cyclic disk wheel, on the rim of which there is an airless bicycle tire, according to the invention, the wheel disk consists of at least two sectors, one of which includes a wheel hub, and the second sector is connected to the first by at least one lock a latch and two or more guide pins.

At the same time, instead of the lock-clamp and guide pins, threaded connections of wheel sectors can be used.

In addition, the airless bicycle tire can also be divided into sectors, each of which is permanently attached to its part of the rim of the wheel sectors.

It is advisable to install a flange sleeve in each end of one of the sectors of the airless bicycle tire, which will include a guide pin installed in each end of the second sector of the airless bicycle tire.

A brief description of the drawings.

FIG. 2. Disassembled wheel variant with sectorless air tire.

FIG. 3. The end faces of the sectors of the airless bicycle tire.

FIG. 4. General view of the folding bike in working condition.

FIG. 5. General view of the folding bike when folded.

FIG. 6. General view of the folding bike when folded with disassembled wheels.

The inventive collapsible wheel (Fig. 1) consists of a sector 1, which includes a wheel hub 2, sector 3, airless bicycle tire 4. Sector 1 is connected to sector 3 by means of a lock-lock 5 and guide pins 6 and 7. Perhaps instead of a lock-lock and guide pins use threaded wheel sectors. In the case of separation of the bicycle airless tire into sectors 8 and 9, each of them is permanently attached to the rims of the sectors of the wheels 1 and 3 (Fig. 2). In order to fix the ends of each sector of the airless tire relative to each other, a flange sleeve 10 is installed in one end, and a guide pin 11 is installed in the response end (Fig. 3).

The implementation of the invention.

A full-size folding bike with a wheel diameter of 26 inches or more with one frame hinge is shown in FIG. 4. Its size L1 (Fig. 5) when folded is determined by the diameter of the wheels and cannot be reduced without removing the wheels in any way, and the removal and subsequent installation of the rear wheel on the bicycle frame requires certain skills, since it involves the removal of the bicycle chain . The inventive collapsible wheel can significantly reduce the dimensions of the bicycle when folded without removing the wheels from the bicycle frame. To do this, the airless bicycle tire is flanged from the rim in the area of sector 3, the locking lock is opened and sector 3 is disconnected from the wheel. Thanks to the use of an airless bicycle tire, there is no need to bleed air during dismantling. If the airless tire is divided into sectors (Fig. 2), then the tire flanging is not needed, since each sector of the tire is permanently attached to its part of the rim of the wheel sector, so sector 3 is disconnected from the wheel together with its sector of the airless tire 9. On rails pins 6, 7 when the bicycle is moving, all the power load transmitted from one sector of the wheel to another is accounted for. So that during the movement of the bicycle, the ends of each sector of the airless tire work together, they are fixed by means of flange bushings 10 and pins 11 installed in each corresponding end. After disconnecting sector 3 from the front and rear wheels, respectively, the size of the full-size folding bike L2 becomes significantly smaller (Fig. 6).

Thus, the creation of a collapsible wheel for a full-size folding bike with a wheel diameter of 26 inches or more, which can be disassembled without removing the wheel from the bike, allows you to combine unlimited road characteristics of a road bike with its compactness when folded.
