Description

  The present invention relates to a marked rim and a manufacturing process thereof.

The mark or decoration of the conventional bicycle rim and frame is attached to the bicycle rim or frame by a water transfer method after the frame or rim is manufactured. When a mark or decoration is to be applied, the sticker is immersed in water and softened, and then attached to a target position to remove air and excess water at the position and remove the sticker from the surface of the sticker. The moisture and residual adhesive are removed and finally the location is completely dried by heating the location at low temperature.
However, such a manufacturing process has the drawbacks that the mark is protruded from the surface of the rim, which is complicated and requires a lot of man-hours.

  A main object of the present invention is to provide a rim with a mark, which has a simple structure of a mark and facilitates a manufacturing process, and a manufacturing process thereof.

  The marked rim according to the present invention includes a rim main body having an outer surface, and a mark fitted to the outer surface and having an outer peripheral edge adjacent to the rim main body, the outer peripheral edge not protruding from the outer surface. .

  The marked rim according to the present invention is characterized in that the rim body includes a number of fibers and a bonding material that bonds the number of fibers, and the bonding material covers the number of fibers and has an outer surface.

  The marked rim according to the present invention is characterized in that the outer peripheral edge and the outer surface have the same height and are adjacent to each other.

  The marked rim according to the present invention is characterized in that the mark is exposed from the outer surface.

  The marked rim according to the present invention is characterized in that the colors of the outer surface and the mark are different from each other.

  The production process of the present invention is applied to the marked rim according to any one of claims 1 to 6, wherein a step of preparing a mold having an inner surface of the mold is performed, and the mark is formed on the outer surface of the rim body and the inner surface of the mold. The method includes the steps of: placing the rim body and the mark in the mold so as to be positioned therebetween; and coupling the mark and the rim body.

  The manufacturing process of the present invention is characterized in that the mark is attached to the rim body or the inner surface of the mold.

  The manufacturing process of the present invention is characterized in that the outer peripheral edge of the mark is continuously attached to the inner surface of the mold.

  The manufacturing process of the present invention is characterized in that the mark and the rim main body are joined by heating.

  The marked rim and the manufacturing process thereof according to the present invention have an effect that the structure of the mark is simple and the manufacturing process is easy.

It is a perspective view showing a rim concerning an embodiment of the invention. FIG. 4 is an exploded perspective view illustrating a method for manufacturing the marked rim according to the embodiment of the present invention. It is sectional drawing of FIG. FIG. 5 is an enlarged view showing a part of FIG. 4. FIG. 6 is an enlarged view showing a part of FIG. 5.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Please refer to FIG. 1 to FIG. The marked rim 1 according to the embodiment of the present invention includes a rim main body 10 and a mark 20.

  The rim body 10 has an outer surface 11. The mark 20 is fitted on the outer surface 11 and has an outer peripheral edge 21 adjacent to the rim main body 10. Since the outer peripheral edge 21 does not protrude from the outer surface 11, the rim 1 is flat and has a good appearance, and the mark 20 is hardly subjected to external force, does not deform, and does not fall off.

The rim main body 10 includes a large number of fibers 12 and a bonding material 13 that binds the large number of fibers 12. The binder 13 covers the plurality of fibers 12 and has an outer surface 11. The multiple fibers 12 employ, for example, carbon fiber, glass fiber, or clovir fiber.
For example, the binder 13 is made of a resin, and can be cured by heating to solidify a large number of fibers 12. However, the rim body may be made of a single material, may be made of another composite material, or may be integrally formed.

  The outer peripheral edge 21 and the outer surface 11 have the same height and are adjacent to each other. Thereby, it is possible to avoid that the mark 20 is pulled and deformed or falls off. In the present embodiment, the entire surface of the mark 20 and the outer surface 11 have the same height and are adjacent to each other. The mark 20 is exposed from the outer surface 11. Since the colors of the outer surface 11 and the mark 20 are different from each other, they are easily identified. However, the outer peripheral edge may be lower than the outer surface.

  The manufacturing process of the marked rim 1 according to the present invention includes the steps of preparing the mold 2 having the mold inner surface 2A and the rim so that the mark 20 is located between the outer surface 11 of the rim main body 10 and the mold inner surface 2A. The method includes a step of inserting the main body 10 and the mark 20 into the mold 2 and a step of connecting the mark 20 and the rim main body 10. As a result, the mark 20 can be quickly and easily coupled to the rim main body 10.

In the manufacturing process of the rim 1, the mark 20 may be attached to the rim body 10 or the inner surface 2A of the mold in advance. In the mold 2, it is preferable that the outer peripheral edge 21 of the mark 20 be in continuous contact with the inner surface 2A of the mold. Accordingly, it is possible to prevent the binder 13 from overflowing into the mark 20 and to stabilize the position where the mark 20 is attached. This makes it possible to prevent the mark 20 from being wrinkled or displaced by receiving a force in the mold 2. Specifically, the mark 20 and the rim main body 10 are connected by heating.
In the present embodiment, the large number of fibers 12 are dry carbon yarns wound around the rim main body 10, the marks 20 are attached to the outer surface 11 of the rim main body 10, and the rim main body 10 is put into the mold 2. After that, the bonding material 13 is injected, and the rim main body 10 is solidified and molded by applying heat and pressure, and at the same time, the mark 20 is bonded. Thereby, a finished product can be obtained directly, and it is not necessary to separately attach a label.
Further, the large number of fibers 12 may be, for example, a fiber material previously infiltrated into the binder 13. Thus, when the rim body 10 is heated and molded by the mold 2, the marks 20 can be similarly joined, and the processing process can be simplified.

  In particular, the mark may be a sticker provided with an adhesive layer, or may not be provided with an adhesive layer, and may be affixed to the rim body by the binder. The mark is a mark structure provided on the inner surface of the mold, and is different in roughness and color by being in contact with the outer surface of the rim main body.

  Although various embodiments and modified examples have been described above, the present invention is not limited to these contents. Other embodiments that can be considered within the scope of the technical concept of the present invention are also included in the scope of the present invention.

The marked rim according to the present invention is characterized in that the exposed surface of the mark and the outer surface of the rim main body have the same height and are adjacent to each other.

The outer peripheral edge 21 of the mark 20 and the outer surface 11 have the same height and are adjacent to each other. Thereby, it is possible to avoid that the mark 20 is pulled and deformed or falls off. In this embodiment, the said rim body 10 of the outer surface 11 and the exposed surface of the mark 20, the height is the same, adjacent to each other. The mark 20 is exposed from the outer surface 11. Since the colors of the outer surface 11 and the mark 20 are different from each other, they are easily identified. However, the outer peripheral edge of the mark 20 may be lower than the outer surface 11 of the rim main body 10 .
