Abstract

The wheel includes a main disk of a solid wheel, two protruding parts protruding from the respective sides of the main disk of the wheel, and two auxiliary parts protruding coaxially from the protruding parts, respectively. The main disk of a solid wheel has an outer diameter larger than the outer diameter of the auxiliary parts. Both the main disk of the wheel and the auxiliary parts are equipped with outer tires made of excellent material. The proposed wheel increases the contact surface with the ground when making a turn and thereby prevents tipping over.

Description

Technical field

This utility model relates to wheels used in vehicles intended for games and sports, such as scooters, three- and two-wheeled bicycles, skateboards, roller skates, exercise bikes, suitcases on wheels, hand trolleys, shopping bags on wheels, toy strollers, and more specifically, to wheels having two auxiliary parts on the respective sides of the main disk of a solid wheel in order to increase the contact surface of the wheel with the ground.

Description of the Prior Art

In most scooters, children's two- and three-wheeled bicycles, wheels B are mounted on trolley A, as shown in Fig. 8, to allow trolley A to move. When trolley A makes a turn, it is difficult to control this turn because wheels B are small. Trolley A can sometimes even roll over if the turn is too sharp.

In order to avoid this drawback, an egg-shaped wheel was developed as shown in FIG. 9, which provides stability when turning. In the ovoid wheel C, the central part of the surface C1 is constantly in contact with the ground. When the trolley A makes a turn, due to the centrifugal force, the trolley A tilts to one side, the same happens with the egg-shaped wheel C. The egg-shaped wheel C is tilted, and its curved surface C2 will be in contact with the ground, as shown in Figure 10, which ensures a stable position of trolley A.

However, if the angle of rotation is too large, then for trolley A there is still the possibility of tipping over.

In order to overcome this drawback, a wheel D was later proposed to which auxiliary wheels D1 were attached, as shown in FIG. 11, which would support the wheel D of the trolley during rotation. However, the auxiliary wheels D1 increase the cost of manufacture and assembly, and also easily break.

ESSENCE OF A USEFUL MODEL

The main goal of this utility model is to create a wheel that would provide a large contact surface of the trolley with the ground and greater stability for users.

Another purpose of this utility model is to create a wheel that uses fewer parts to assemble, which saves assembly time and creates less noise during operation.

Another purpose of this utility model is to create a wheel that includes a main disk of a solid wheel and auxiliary parts made with it in one piece by blow molding or injection molding. The wheel is provided with an outer tire formed by injection or molding, or mounted on the wheel, which is preferable in terms of cost-effectiveness.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS FOR USING THE USEFUL MODEL

As shown in FIG. 1, a first embodiment of this utility model includes a wheel 1 having a main disk 11 of a solid wheel in the middle portion for direct contact with the ground. The sides of the main drive 11 of the solid wheel are spaced apart so as to create two protruding parts 12 that come into contact with the ground when making a turn. Each protruding part 12 extends outward and forms an auxiliary part 13. The main disk 11 of the continuous wheel 1 has an outer diameter larger than the outer diameters of the auxiliary parts 13, so that when making turns the contact surface with the ground increases. Auxiliary parts 13 are performed in one piece with the main disk 11 of the solid wheel.

To use this utility model, as shown in FIG. 2 and FIG. 3, wheel 1 is mounted on the axis of trolley A. When trolley A rolls in

in the rectilinear direction, the main disk 11 of the continuous wheel 1 is in contact with the ground. When the trolley A makes a turn, then, thanks to the centrifugal force, the wheel 1 tilts together with the trolley A, which forces one of the protruders to come into contact with the ground parts 12. The auxiliary part 13 will also be in contact with the ground, which increases the contact surface between the wheel 1 and the ground and will provide stability when rolling in case the rotation angle is too large.

A second embodiment of this utility model includes a wheel 1A as shown in FIG. 4. The wheel 1A has a solid-state main disk HA in the middle part, two protruding parts 12A protruding from the respective sides of the main solid-wheel disk HA, and two auxiliary parts 13A protruding coaxially from the protruding parts 12A, respectively. The main disk ON of the solid wheel 1A has an outer diameter larger than the outer diameters of the auxiliary parts 13A. The protruding parts 12A are located at some distance from the auxiliary parts 13A.

A third embodiment of this utility model includes a wheel 1B, as shown in FIG. 5. Wheel 1B includes a solid-state main disk 11B in the middle portion that is in contact with the ground when the trolley rolls. The sides of the main solid wheel drive 11B are spaced apart so as to create two protruding parts 12B and two auxiliary parts 13B protruding coaxially from the protruding parts 12B, respectively. The main disk 11B of the solid wheel 1B has an outer diameter larger than the outer diameters of the auxiliary parts 13B. The protruding parts 12B are at some distance from the auxiliary parts 13B.

A fourth embodiment of this utility model includes a wheel 1C, as shown in FIG. 6. Wheel 1C includes a solid-state main disk 11C in the middle portion that is in contact with the ground when the trolley rolls. The main drive 11C solid wheels side

the sides are spaced apart in order to create two protruding parts 12C and two auxiliary parts 13C protruding coaxially from the protruding parts 12C, respectively. The main disk 11C of the solid wheel 1C has an outer diameter larger than the outer diameters of the auxiliary parts 13C. The protruding parts 12C are at some distance from the auxiliary parts 13C.

A fifth embodiment of this utility model includes an ID wheel, as shown in FIG. 7. The ID wheel includes a center disk 1 ID of a solid wheel in the middle portion that is in contact with the ground when the trolley rolls. The sides of the main solid disk 11D of the solid wheel are spaced apart so as to create two protruding parts 12D and two auxiliary parts 13D protruding coaxially from the protruding parts 12D, respectively. The main disk 11D of the solid ID wheel has an outer diameter larger than the outer diameters of the auxiliary parts 13D. The protruding parts 12D are at some distance from the auxiliary parts 13D.

In addition, the solid wheel main disk 11D is provided with an outer tire 110D made of excellent material. The auxiliary parts 13D are also provided with outer tires 130D made of excellent material. The outer tires 110D and 130D may be injection or injection molded, or mounted directly on the wheel. The outer tires 110D and 130D have outer diameters larger than the outer diameters of the main solid disk 11D and the auxiliary parts 13D.
