Description

Weights for bicycle wheels and bicycle wheels provided with the weights

The invention relates to a weight member, in particular to a weight member mounted on a bicycle wheel.

The counterweights are mounted on the wheels of vehicles such as steam locomotives to correct the problem of external forces acting on the wheels during the manufacturing process or driving, resulting in a central offset or imbalance of center of gravity. Conventional counterweights such as the Republic of China According to the patent M363400, the adhesive layer adheres the weight member to the inner side of the rim, so that the tire can be rotated in a balanced manner, thereby improving the problem of the eccentric structure of the wheel.

However, the above-mentioned weight member is fixed on the rim only by the adhesive method. When the vehicle is running at a high speed, the weight member is often pulled out due to the vibration or centrifugal force of the rim, and the adhesive layer is easy to use under long-term use. Due to the humid or high temperature of the use environment, the adhesive loses the adhesive force to separate the weight member from the rim. It is worth noting that for bicycle users, especially professional cyclists, the weight of the air nozzle on the bicycle wheel will cause eccentricity problems in the overall structure of the rim, and the centrifugal force generated by the eccentric structure under high-speed rotation of the vehicle. It is easy to make the bicycle shake when driving and affect the smoothness and stability of the pedaling. There may even be safety concerns during long-time high-speed driving. Although there are other related researches on weights, most of them are heavy-duty vehicles such as cars or locomotives.

In view of this, in order to provide a solution to the above conventional structure, the eccentricity problem caused by the weight of the bicycle wheel nozzle can be solved. Accordingly, the present invention provides an innovative weight member as described in the detailed description below.

The main object of the present invention is to provide a weight member that can be quickly and easily fixed to a bicycle wheel by a user, and the weight member can be firmly disposed on the wheel to be easily detached.

Another object of the present invention is to provide a weight member that corrects the eccentricity problem caused by the weight of the nozzle of the bicycle wheel.

In order to achieve the above object, the present invention provides a weight member for a bicycle wheel, the weight member being made of a material that can be bent and formed, wherein at least one weight portion extends from opposite ends of the connecting portion. Thereby, the connecting portion can be bent and fixed into a U shape, so that the two weight portions are relatively clamped on both sides of the inner edge of the wheel, so that the weight member can be completely clamped to the wheel and correspondingly The position of the gas nozzle is not easy to fall off, thereby correcting the eccentricity problem generated by the gas nozzle. Moreover, the connecting portion can also be bent into a shape so that the two weight portions can be quickly separated from the wheel, so that the user can adjust the clamping position and repeatedly use the weight member on the other wheels.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to Figure 1, the present invention provides a weight member 1 for mounting on a bicycle wheel having a rim 2, a plurality of spokes 3 and a nozzle 4, the nozzle 4 being attached thereto. On the rim 2, the strips 3 are radially arranged to connect the rim 2, as shown in FIG.

Referring to FIGS. 2 and 3 , the weight member 1 has a connecting portion 10 and two weight portions 11 . The connecting portion 10 is made of a material that can be bent and formed. In the embodiment, the connecting portion 10 is made of a flexible alloy material such as copper, iron, tin or lead, and the connecting portion 10 is made. It can be bent and fixed by the user. In other possible embodiments, the connecting portion 10 is made of a non-metallic material such as synthetic film which can be bent and formed. The two weight portions 11 are respectively connected to opposite ends of the connecting portion 10, and the two weight portions 11 are symmetrical and equal in weight. Preferably, the two weight portions 11 are respectively formed with a marking portion 12, and more specifically, the marking portion 12 protrudes perpendicularly from the plane of the weight portion 11 and forms a predetermined character or pattern. The relevant product information of the weight member 1 is marked or the appearance of the weight member is recognized.

In addition, the weight member 1 can be integrally formed, and the two weight portions 11 are integrally extended from the two ends of the connecting portion 10, thereby having a good connection structure strength, wherein the connecting portion 10 is extended and connected to each of the weights. The middle portion of the side of the weight portion 11 and the upper and lower free ends of the weight portion 11 extend away from each other, so that the weight member has an H shape, as shown in FIG. 2 . Thereby, the weight member 1 can be more evenly distributed on the rim 2, and the elongated extension portion 11 can also have a larger surface area so that the indicator portion 12 can clearly highlight the existing Product information or trademarks are on it to achieve advertising and brand recognition. Furthermore, in the embodiment, the connecting portion 10 and the two weight portions 11 are substantially in the form of a sheet, whereby the connecting portion 10 can be easily bent by the user, and the two weight portions 11 can be flattened. Attached to the bicycle rim 2, as shown in Figure 3. In other possible embodiments, the weight member 1 can be formed with an adhesive layer. In other words, the two weight portions 11 can be formed with an adhesive layer relatively away from the surface of the indicator portion 12, so that the weight member can be The adhesive is attached to the rim 2 of the wheel without being easily shaken.

Referring to FIG. 1 and FIG. 4, the weight member 1 can be bent into a U shape by the connecting portion 10 so that the two weight portions 11 can be close to each other, so that the connecting portion 10 can be clamped to the bicycle wheel. On the rim 2, the two weight portions 11 are respectively abutted against the two sides of the inner edge of the rim 2, so that the weight member 1 is clamped and fixed to the position of the rim 2 corresponding to the nozzle 4. More specifically, the connecting portion 10 can be fixed and shaped corresponding to the transverse contour of the inner edge of the rim 2, so that the connecting portion 10 and the two weight portions 11 are smoothly fitted to clamp the rim. 2, as shown in Figure 4. In addition, when the weight member 1 is clamped to the rim 2, the indicator portion 12 can be exposed on the outer side of the weight member 1, as shown in FIG. Since the general bicycle wheel often uses surface treatment to mark existing product information such as product model or trademark pattern on the rim during the production process, the finished wheel cannot change the existing brand mark on the rim, but only Provided to a specific customer or manufacturer, in contrast, the weight member 1 of the present invention can utilize the indicator portion 12 to provide the bicycle wheel with product information or trademark without marking the specific product information when the rim is produced. In this case, it is only necessary to clamp the weight piece corresponding to the specific brand or product information on the rim 2 before shipment, so that the production of the bicycle wheel can be more flexible and will not increase. The burden of production costs.

In summary, the weight member 1 provided by the present invention can be easily and quickly bent and fixed to the position of the rim 2 corresponding to the air nozzle 4, thereby balancing the whole of the rim 2 Weight, and correcting the eccentricity problem caused by the weight of the nozzle 4; and the centrifugal force generated when the rim 2 rotates can further fit the styling structure formed by bending the connecting portion 10 into the rim On the edge, it is not easy to produce loose phenomenon. In addition, the connecting portion 1 can be repeatedly bent and restored to a flat shape, in addition to adjusting the clamping position of the weight member, and can be sandwiched on other different bicycle rims, thereby achieving the effect of repeated use. It is very convenient to use, it is a proof of progress.
