Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to a bicycle rim. More specifically, Shuming is about a lightweight bicycle rim with sufficient strength: preferably = containing the upper (radially outer) metal portion and the lower (radially inner) non-metallic portion of the lightweight composite rim. [Prior Art] r' V.., / Since the two-wheels are usually redesigned to be rugged and lightweight in design, the two are: aerodynamic and designed to be easy to manufacture and assemble. Two: 1": Many different types of bicycles purchased on the market. Two-edge U-deck wheels have a hub, a plurality of spokes and a ring. Two wheels = one part of the frame of the bicycle for relative rotation. The inner end of the special wheel is coupled to the rim. The rim is used to connect to the wheels. The outer end of the ring H 1 field has an outer portion for an aeration wheel θα on the upper branch. So far, it has gone awry; However, it is not easy to achieve these two features with the light and strong enough wheel. For example, if the rigidity of the %-shaped side wall of the tax-reducing edge is insufficient, then / in order to be light or if the force of the inner tube of the tire of the annular side wall J (four) the outer part of the side wall may be attributed to from a "" It is expected that a non-metallic material that is rigid when all or at least a portion of the side wall is made of a metal material and a Wang 丨 to V # 分 resin material (such as, in view of the above, it is obvious that There is a need for this technology to improve the rim of the present invention. The present invention solves the problem of 129246.doc 200909242. This is the love of the art i R #一八他八' needs to be familiar with the technology This situation will become apparent from this disclosure. [Invention] The goal is to provide a rim for a bicycle wheel that is relatively strong and still relatively lightweight. - a bicycle rim to achieve the above goal, = from: D: the rim includes a metal outer portion and - fixedly attached to the gold: a portion of the non-metallic inner portion. The metal outer portion includes a a metal-shaped side wall and a metal annular wall extending between the 5 荨 metal annular side walls, wherein the metal annular wall includes a thickened central portion and is laterally positioned relative to the central portion (thinner/minus Thin side portion. In the y = embodiment, the central portion of the thickening is aligned with the central plane p of the rim, in particular such that the central plane p of the rim passes through the added portion. In a preferred embodiment, The metal annular wall is curved radially inwardly. In the preferred embodiment, the central portion of the thickening forms a concave first continuous curved surface with the side portions. In the preferred embodiment, the center of the thickening a second surface that is convex with the sides. In a preferred embodiment, the thickness of the metal annular wall is progressively and/or continuously from the core end region of the side portions toward the thickened central portion. In a preferred embodiment, the I-ring wall (specifically, the central portion of the thickening) is at least partially surrounded by the non-metallic inner portion (embedded in the non-metal I29246.doc 200909242 internal portion). Good example The non-metallic inner portion includes a thickened region positioned in a generally v-shaped configuration. In a preferred embodiment, the non-metallic inner portion includes a non-metallic annular shape: the non-metallic annular outer wall has a radial An outwardly facing surface that is concave and fixedly attached to the outer portion of the metal. In a preferred embodiment, the 'non-metallic inner portion further includes one and a plurality of spoke attachment openings. Forming - generally ... 袠 ... and - for a non-metallic ring to take a generally rectangular hollow profile. 22: In the embodiment, the non-metallic annular inner wall is thicker than the non-metallic and / non-metallic annular outer wall. Or in the embodiment, The lateral outer region of the non-metallic annular outer wall and /; eight: ring: the radially outer region of the shaped sidewall is thicker than the intermediate portion of the non-metallic annular sidewall.

According to a preferred embodiment, one of the above features may be included in the bicycle rim. Where appropriate, the above features may be combined in any way. The present invention, as well as the accompanying drawings, will be apparent from the accompanying drawings. [Embodiment] Reference is now made to the accompanying drawings which form a part of this original disclosure. .f ' ο The selected embodiments of the present invention will now be described with reference to the drawings. It will be apparent to those skilled in the art that the present invention is intended to be illustrative only and not to limit the scope of the invention as defined by the scope of the appended claims DESCRIPTION OF THE PREFERRED EMBODIMENTS Figure 1 shows an enlarged cross-sectional view of a composite rim i of a front wheel in accordance with a first embodiment of the present invention. Although only the rim 1 of the front wheel is illustrated herein, the present invention can be applied to the front and rear wheels in the same manner. The rim 丨 is a so-called complex I rim 'which basically comprises two parts 'that is, 'the metal outer part 2 and the non-metallic inner part 3 which is integrally combined with the metal outer part 2 3 ^ metal outer part 129246.doc -11 - 200909242 points 2 constructed from any suitable metallic material, such as aluminum, town or titanium. The non-metallic inner portion 3 is constructed from any suitable non-metallic material well known in the art, such as a fiber reinforced plastic/resin material. The metal outer portion 2 basically comprises a metal annular wall 5 and a pair of metal annular side walls 4 adapted to mount a tire having a tube (or a tire without a tube) thereon. Each metal annular side wall 4 forms a factory annular braking surface 4a at its outer surface to engage a conventional rim brake and forms an annular rib W at its (radially outer) free end for use in a conventional manner Hold the bead of the tire. The metal annular side wall 4 further includes an outer portion, the inner portion (four) being intermediate portion 4e between the outer portion 4b and the inner portion 4c. The thickness u of the rotating portion 4b is larger than the thickness t2 of the inner portion. The preferred embodiment of the towel shown in Fig.!, the thickness of μ#(4), and the thickness of the inner portion 4e is 14_. As shown in Fig. 1, the metal The annular wall 5 extends between the metal annular side walls 4 and is fixedly coupled to the metal annular side wall 4 at a portion 4e between the metal ring (4) 4. The pair of metal annular side walls 4 and the metal annular wall 5 form a substantially meandering transverse direction. The metal annular wall 5 has a thickened central portion at the intermediate portion, which is called a thickened portion, and the middle portion of the central portion 5a is contained in a central plane p of the rim and has (4) Having the second thickness t4 of the reduced thickness - the opposite side portion 5b. Specifically, the thickened central portion 5a and the center plane p of the central edge of the rim pass through the thickened center adjacent to the eighth s λ ambulance wheel #5a. The second thickness is reduced by 44 degrees t3. In the preferred embodiment shown in Figure 1, the first-dryness t3 is 1.4 mm and the second thickness 〇_. 129246.doc -12· 200909242 As shown in the article, the metal ring is made to bend inward and bend inward. In contrast to 5b, the thickened central portion knife 21 has a smaller radius with respect to the central rim axis (not shown). The thickening of the r 4 points 5a forms a first continuous (gradual) curvature with the side portion 5b. The surface 6a of the coin is concave. The first surface 6a faces radially outward. The other thickened central portion 5a and the side portion 5b form a second surface 讣. The first surface 6b is convex. The second surface 6b faces radially inwardly. In the illustrated embodiment, by the two lateral sides of the central portion 5a of the thickened f (i.e., the thickened central portion & and the side portion 5b) Forming a class, a knife step 5d, the thickness of the metal annular wall 5 is gradually increased from the lateral end region 5 of the side portion 5b toward the C toward the thickened central portion 5a.
