Abstract

A wheel structure includes a main wheel body, a pair of extension sections extending from respective sides of the main wheel body, and a pair of auxiliary sections coaxially extending from the extension sections, respectively. The main wheel body of the wheel has a larger outer diameter than the outer diameters of the auxiliary sections. Both the main wheel body and the auxiliary sections are provided with outer tires made in a different material. The wheel increases contact surfaces with the ground when making turns, so as to prevent overturning.

Description

TITLE: WHEEL STRUCTURE
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to a wheel structure applied to playing or sporting vehicles such as scooters, tricycles, bicycles, skateboards, roller skates, training cycles, hand-pulling suitcases, hand carts, shopping carts, toy carts or balancing wheels, and more particularly to a wheel having two auxiliary sections at respective sides of a main wheel body to increase contact surfaces of the wheel with the ground.
Description of the Prior Art
Most scooters, tricycles or bicycles for children are mounted with wheels (B) to a cart (A), as shown in Figure 8, to facilitate movement of the cart (A). When the cart (A) makes a turn, it is difficult to control turning movement because the wheels (B) are small in size. Sometimes the cart (A) may even turnover if the turn is made too wide.
In order to correct the shortcoming, an egg-shaped wheel (C) was derived, as shown in Figure 9, to provide the stability when making turns.
The egg-shaped wheel (C) has its center surface (C I) in touch with the ground constantly. When the cart (A) is turning, due to the centrifugal force, the cart (A) leans towards one side, and so does the egg-shaped wheel (C). The egg-shaped wheel (C) will lean with its arc surface (C2) to get in touch with the ground, as shown in Figure 10, which provides a stable position to the cart (A). However, if the turning angle is too big, the cart (A) still may encounter the possibility of overturning.
In order to overcome the above-mentioned shortcoming, a wheel (D) mounted with auxiliary wheels (Dl) is derived later, as shown in Figure II, to support the wheel (D) of the cart in turning. However, the auxiliary wheels (Dl) increase the cost of manufacture and assembly, and it easily malfunctions.
SUMMARY OF THE INVENTION
It is the primary objective of the present invention to provide a wheel structure, which provides with more contact surfaces for a cart to get in touch with the ground and more stable to riders.
It is another objective of the present invention to provide a wheel structure, which uses less parts to save time in assembly and has less noise.
It is a further objective of the present invention to provide a wheel structure, which comprises a main wheel body and auxiliary sections formed integrally by blowing molding or injection molding. The wheel is provided with an outer tire formed in an injection or casting method or mounted to the wheel, thus it is cost effectiveness

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in Figure II, a first embodiment of the present invention comprises a wheel (1) having a main wheel body (11) at the center portion for direct contact with the ground. The main wheel body (11) has its two sides extending to form a pair of extension sections (12) to get in touch with the ground when making turns. Each extension section (12) extends outwardly to form an auxiliary section (13). The main wheel body (II) of the wheel (1) has a larger outer diameter than the outer diameters of the auxiliary sections (13) to increase the contact surfaces with the ground when making turns. The auxiliary sections (13) are integral to the main wheel body (11).
To operate the present invention, as shown in Figures 2 and 3, the wheel (1) is pivotally connected to a cart (A). When the cart (A) is rolling in a straight direction, the main wheel body (11) of the wheel (1) remains contact with the ground. When the cart (A) makes a turn, due to the centrifugal force, the wheel (1) will incline with the cart (A), which makes either extension section (12) touch the ground at this moment.
The auxiliary section (13) is also in touch with the ground to increase contact surface between the wheel (1) and the ground to provide a steady riding status when the turning angle is too big.
A second embodiment of the present invention comprises a wheel (1A) as shown in Figure 4. The wheel (IA) has a main wheel body (1 1A) at the center portion, a pair of extension sections (1 2A) extending from respective sides of the main wheel body (1 1A), and a pair of auxiliary sections (13A) coaxially extending from the extension sections (12A), respectively. The main wheel body (1 1A) of the wheel (1A) has a larger outer diameter than the outer diameters of the auxiliary sections (13A).
The extension sections (12A) are spaced from the auxiliary sections (13A).
A third embodiment of the present invention comprises a wheel (IB), as shown in FIG. 5. The wheel (1B) comprises a main wheel body (I 1B) at the center portion to be in touch with the ground when the cart is rolling. The main wheel body (1 1B) has its two sides extending outwardly to forni a pair of extension sections (1 2B) and a pair of auxiliary sections (1 3B) coaxially extending from the extension sections (12B), respectively. The main wheel body (11 IB) of the wheel (1B) has a larger outer diameter than the outer diameters of the auxiliary sections (13B). The extension sections (12B) are spaced from the auxiliary sections (13B).
A fourth embodiment of the present invention comprises a wheel (1 C), as shown in Figure. 6. The wheel (1C) comprises a main wheel body (11 C) at the center portion to get in touch with the ground when the cart is rolling. The main wheel body (II 1C) has its two sides extending outwardly to form a pair of extension sections (12C) and a pair of auxiliary sections (1 3C) coaxially extending from the extension sections (12C), respectively. The main wheel body (1 IC) of the wheel (1C) has a larger outer diameter than the outer diameters of the auxiliary sections (13C). The extension sections (12C) are spaced from the auxiliary sections (13C).
A fifth embodiment of the present invention comprises a wheel (1D), as shown in Figure 7. The wheel (1D) comprises a main wheel body (liD) at the center portion to get in touch with the ground when the cart is rolling. The main wheel body (1 1D) has its two sides extending outwardly to form a pair of extension sections (12D) and a pair of auxiliary sections (13D) coaxial])' extending from the extension sections (12D), respectively. The main wheel body (I 1D) of the wheel (1D) has a larger outer diameter than the outer diameters of the auxiliary sections (13D). The extension sections (12D) are spaced from the auxiliary sections (13D).
Furthermore, the main wheel body (1 1D) is provided with an outer tire (1 IOD) made in a different material. The auxiliary sections (13D) are also provided with outer tires (130D) made in a different material. Both the outer tires (1 1OD) and (130D) may be formed in an injection or casting method or mounted directly to the wheel. Both the outer tires (I I OD) and (I 30D) have larger outer diameters than the outer diameters of the main wheel body (lID) and the auxiliary sections (13D).
