Description

Bicycle wheel {WHEEL FOR BICYCLE}

The present invention relates to a bicycle wheel, and more particularly, to a bicycle wheel having an integrated spoke to enable the balance adjustment.

Conventional bicycle wheels include a central hub supporting a rotating shaft, a plurality of spokes extending radially from the hub, and a rim coupled to an outer end of each spoke.

However, according to such a conventional bicycle wheel, there was a problem in that it was very inconvenient because it was based on a method of checking the balance while adjusting the length of each spoke in order to balance the wheel.

On the other hand, in the case of the disc-shaped spokes are formed integrally with the inner end and the outer end are integrally coupled to the hub and the rim, there is a problem that once the balance is displaced, it is impossible to fit them, so that a new one must be replaced. .

It is an object of the present invention to provide a bicycle wheel that is provided with an integrated spoke and is easy to install as well as to adjust the balance.

In order to achieve the above object, the present invention provides a bicycle wheel, a hub having a pair of fastening disks integrally coupled to both end surfaces of a cylindrical body in which a shaft hole is formed in a circumferential direction at regular intervals. Wow; A circular opening is formed at the center of the shaft hole, and a plurality of coupling holes corresponding to the fastening holes of the one-side fastening disk are formed at regular intervals in the circumferential direction. A first spoke body in which a plurality of spokes are formed at regular intervals and a rim fastening hole is formed at an outer end of each spoke; In the center is formed a circular opening arranged around the axial hole, around the circular opening a plurality of coupling holes corresponding to the fastening holes of the other fastening disk is formed at regular intervals in the circumferential direction, A second spoke body in which a plurality of spokes are formed at regular intervals and a rim fastening hole is formed at an outer end of each spoke; It is provided on the outside and the first and second spoke body, the inner side includes a plurality of spoke fasteners interposed between the outer end of each spoke of the first and second spoke body includes a wheel rim formed at regular intervals in the circumferential direction It provides a bicycle wheel, characterized in that.

Here, the central portion of each spoke of the first and second spoke body may be adjusted to be coupled through the fastening disk and the adjustment bolt.

In addition, the first and second spoke bodies each have a bent portion such that each center portion is inclined inward toward the hub at an end portion forming the opening, and the bent portion is elastically deformed by adjusting the adjusting bolt. It may be provided to enable.

According to the bicycle wheel according to the present invention, the first and the second spoke body is formed in one piece, respectively, is easy to install and coupled to the inner hub and the outer rim, as well as the inner side of each spoke body coupled to the hub side By adjusting the coupling force at the end, such as by adjusting the coupling force to generate an elastic deformation it is possible to easily adjust the balance of the wheel.

1 is a front view of a bicycle wheel according to an embodiment of the present invention,
2 is a partial cross-sectional view showing a coupling state between the hub and the spoke body constituting the bicycle wheel of FIG.

Bicycle wheel 100 according to an embodiment of the present invention, as shown in Figure 1, the center hub 110, the first and second spoke body 120, 130 that is bolted to the hub 110 ), Rim 140 is coupled to the outer end of each spoke body (120, 130), it is configured to include a tube 150 coupled to the outside of the rim (140).

The hub 110 has a cylindrical main body 111 having a shaft hole h formed therein, and a pair of fastening disks 112 having a plurality of fastening holes 112h and 113h circumferentially formed at both ends thereof at regular intervals. 113 is integrally combined.

The first spoke body 120 and the second spoke body 130 are formed in the same symmetrical arrangement with each other, and when the first spoke body 120 is representatively described, the circumference of the shaft hole (h) in the center A circular opening o is formed, and a plurality of engaging holes 120h corresponding to the fastening hole 112h of the fastening disk 112 are circumferentially formed around the circular opening o. It is formed at regular intervals, a plurality of spokes 121 are formed at regular intervals in the circumferential direction and the rim fastening hole 121h is formed at the outer end of each spoke (121).

Rim 140 is provided on the outside of the first and second spoke body (120, 130), the inner end of each spoke (121, 131) of the first and second spoke body (120, 130) A plurality of spoke fastening pieces (not shown) interposed therebetween are formed at regular intervals in the circumferential direction.

At this time, the center of each spoke (121, 131) of the first and second spoke body (120, 130) is adjustablely coupled through the fastening disk 112, 113 and the adjusting bolt 160.

The adjusting bolt 160 is provided with a spring 161 to close each spoke body (120, 130) to the fastening disk (112, 113) in the elastically inward direction.

In addition, the first and second spoke bodies 120 and 130 form the bent portions 122 and 132 such that each of the central parts thereof is inclined inward toward the hub 110 at an end portion forming the opening o. By the adjustment of the adjusting bolt 160, the bent portions 122 and 132 are provided to enable elastic deformation.

Accordingly, the flexures 122 and 132 are elastically deformed by pressing through the adjustment of the adjustment bolt 160, resulting in a unilateral load applied to the engagement with the rim (140 in FIG. 1) coupled to the outer end. Balance adjustment of the bicycle wheel 100 is achieved.

On the other hand, since the bicycle wheel 100 described above is only an embodiment to help understanding of the present invention, the scope of the present invention should not be understood as being limited to the scope of the present invention.

The scope of the invention to the technical scope is defined by the claims and equivalents described below.
