Description of the invention: [Technical field to which the invention pertains] - The present invention relates to a bicycle-specific composition and a component, and the negative-acting member of the type includes a composite oyster of an embedded sheet ^ ,. The embedded segment is covered by a layer of exoskeleton fibers. [Prior Art] A number of composite structures are known from the state of the art, which provide an optimum balance: on the one hand, the structure is as light as possible, and on the other hand, the structure is sufficiently strong. : As in the bicycle industry, is it known that most of the crank arms in the composite crank arm are bamboo? The coating is formed and the epoxy resin is molded and cured into a specific shape. In order to provide a secure attachment position for mounting the pedal to the crank arm and for mounting the crank arm itself to a crank axle, a metal insert is provided at the outer end of the crank arm. During manufacture, the metal inlay sheets are overcoated with an outer carbon fiber layer, which is also referred to as an outer bone (four) fiber layer and is joined to the "metal" insert by curing the epoxy resin. The ring is cured. The oxyresin has two first CH 匕 which will harden the outer bone fiber layer, and secondly, the solid (tetra) epoxide (four) will fix the t-way carbon fiber layer to the metal insert. Fixed (threaded) attachment holes are fixed. However, one of the disadvantages of the known composite crank arms is that they are metal inserts, they are known to be compounded.

They are known to have a composite crank arm that is often not strong enough during a fatigue test or for a long normal ride. === Enough (four) force. The fragments of the metal inlays may be released from the outer cladding of the outer layer of the cured exoskeleton carbon fiber. U.S. Patent No. 6,564,675 shows a crank arm for a bicycle. The crank arm includes a metal pedal mounting inlay and a metal wheel. The insert is mounted to each other by a hollow tube. A composite material, such as carbon fiber, is applied to the outer surface of the hollow tube and the two (four) sheets. To further reinforce the assembly, a bond strip is wrapped around the ends of the hollow tube to secure the assembly midsheet. One disadvantage of this known crank arm is that the crank arm is still relatively heavy and fragile. The hollow tube is necessary to reinforce the crank arm, and the hollow tube adds weight to the crank arm, along with the bond strip to help prevent the sheet from loosening out. In addition, although a clad connection is provided between the embedding sheets and the hollow tube, when the load applied by the rider to the pedal is high, the embedded sheets are loosened. The situation may still occur. This situation may occur during periods such as rapid acceleration, steep slopes, and/or competition. [SUMMARY] or at least one light weight and robustness The present invention is directed to overcoming one or more of the above disadvantages, and alternatives are available. DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to providing a load member of 201226253 which can be easily and reliably manufactured. This goal is achieved by a load component as described in claim i. The member includes alternating stacking of at least one of the two embedded segments, an intermediate sheet of fibrous layer extending between the two aged segments. The intermediate laminar fiber has a towel-to-fiber portion which is stacked adjacent to the adjacent outer side of the central fiber-retaining portion adjacent to the embedded segment and secured to the adjacent outer sides on both sides. The intermediate flaky fiber layer additionally has an outer fiber fixing portion protruding from the outer fiber fixing portion to the outside of the segment, so as to form a solid with the other fiber layer, Al u The outer layer of exoskeleton fibers is formed to form at least one of the outer surface of the outer surface, and has sufficient strength to substantially shape/shape the member, and bear the load; ^ a outside the load acting on the outer surface The fiber and the quasi-layer are fixed to at least a portion of the outermost layer of the embedded segment stack and cover the side sills of the outermost sills 4 and the outer layer of the flaky fiber layer Eight very At β which 1, only the back part of the knife is at least the outermost outer side of the knife and covers the most side holes extending through the side of the ice ice 4 side. One attached ' Η wear the outer ... fiber layer, a plurality of stacked embedded a segment and a central fiber fixing portion of the intermediate flaky fiber layer. The exoskeleton fiber layer, the embedded segment, the segment, etc. are alternately stacked to form an ampo layer, a very strong oil And forming one of the fiber layers into the fiber layer material. According to the invention, the two layers of material are encapsulated and layered. The fragments are entangled to some extent; The composite stack of the embedded sheet and the quasi-(3) material is integrated into the light weight component 201226253. One of the fiber layers is permanently fixed and firmly bonded to prevent the stacked assembly from being embedded during the heavy load. The stack of individual encapsulated embedded segments is more securely attached and more capable of carrying the load attached to the other of the stacked individual embedded segments, in particular with a solid single package, as compared to current state of the art structures. The same is true for one of the individual exoskeleton fiber layers of the insert sheet (the solid single insert size being the same as the stack size of the individual encapsulated inserts according to the invention). Even if one of the embedded segments is from The entire or part of the encapsulating fibrous layer material of the segment is detached, and the situation still does not immediately result in forced complete failure. In other cases, other embedded segments remain retained by the The remaining portions of the intermediate fiber layer and the exoskeleton fiber layer are covered and fixed to the remaining portions of the intermediate fiber layer and the exoskeleton fiber layer. The focus is on the embedded segments, which can be easily embedded in each other, so that the embedded The segments are easily fabricated into a variety of shapes and are reliably stacked on top of each other. Preferably, the embedded segments are plate shaped and inexpensive, and are easy to stack. In a particular embodiment, the attachment is in the attachment. The hole has been tapped (4)) a striated line extending through the individual embedded segments. The thread allows the cow to be quickly and easily attached to the load member... and the other object is inserted into the threaded attachment hole The hair stack assembly that assists further integration and maintains the embedded sheets is secured together. Thus the attachment of another item is stepped up to strengthen the member and prevent the embedded segments from coming out of it. In a further embodiment, the embedded segments are between 75 and 1.5 times the pitch. Therefore, it is ensured that the thread can pass through the individual embedded Ηq+ pieces & 2012, and there is a sufficient number of envelope segments in the 冋. • In detail, each of these embedded segments has a thickness of 0.5 to 3 millimeters.

Each of the intermediate flaky fiber layers has a thickness in the range of (M - 1 〇.3 胄m. The ranges appear to be well matched and provide a stable and rigid fixed stack. Therefore, the surrounding of the attachment holes The central segment stacking portions of the embedded segments can be held relatively close to each other while the outer fiber fixing portions of the intermediate fiber layer can be placed close to the other interfiber layers, and The skeletal fiber layer is nearly offset. ^- In the preferred embodiment, 'at least three embedded segments are stacked on top of each other'. At least two intermediate flaky fiber layers are placed between each other. Alternating use with at least four intermediate laminar fibrous layers. In a variant, the embedded segments further comprise an outwardly radially projecting projection of the field slaves in addition to a stack of sheets surrounding the one of the attachment holes Accepting a portion of the tail segment of the portion, the tail segment = abundance portion is made thinner than the central segment stack portion. At the thin end of the board, the ρ portion is 'the intermediate fiber layer material can be Slightly more freely = gathered and formed securely with the embedded segments. The tail piece stacking portions preferably extend in the longitudinal direction of the member and thus help to improve the load member in the longitudinal direction Strength and rigidity. The fiber layer of U and other embedded segments can be fixed to each other in a variety of ways. J. If various types of adhesives are available, preferably these fiber layers (these are in the middle of 201226253 and in the outer layers of the exoskeleton) A curing resin is included (eg, a cured epoxy resin that cures the fibrous layers to each other and to the embedded segments. Further, the cured resin provides rigidity to the various fibrous layers, and thus the entire member Providing rigidity. The fibrous layers may comprise all kinds of fibers, such as carbon fibers, glass fibers, and/or vinyl ester fibers. The embedded segments are preferably sized such that the surface area of the embedded segments is at least The surface area of the contact hole is 8 times the size. This appears to be sufficient for the attachment of the embedded segments to the specific size of the fiber layers. For the same reason, the surface area dimensions of the intermediate W-shaped fibrous layers are made at least 8 times the surface area size of the embedded segments. The preferred embodiment of the present invention is attached. The present invention is also directed to an application (particularly as a crank arm) as a load member for a bicycle component and a method for manufacturing the same. [Embodiment] FIG.

Fiber and / or B-based fiber. . Hei Shu knows for example _ oxy resin. Other types of fibers or resins can also be used. The embedded segments 2 are plate-shaped and are made of a rigid material, particularly a metal such as aluminum. Each segment 2 includes a circular center: a slave stack portion 5 and two tail segment stack portions 6, the two tail segment stack portions extending from the n-segment stack portion 5 in opposite lateral directions. The center segment stacking portion 5 has a constant thickness. The tail piece stacking portion 6 is tapered toward the outside, and thus the tail piece stacking portion 6 is made thinner than the center piece stacking portion 5, and the tail #slice stacking portion 6 is one of the longitudinal rectangular fiber layers The longitudinal direction X extends. In a second step, the layers of alternating fiber layer i and embedded segment 2 are placed in a model in the correct order. In this way, the central segment stack portions 5 are placed on each other in a straight line. Each of the intermediate fiber layers has a portion extending between the centers of the embedded segments 2 and the tail sheets & stack portions 5 and 6. This portion is referred to as the central fiber fixing portion 8 (see Fig. 2). Further, each of the intermediate fiber layers 1 b has a portion laterally larger than the outer side of the embedded segments 2. This portion is referred to as an outer fiber fixing portion 9. After being placed in the mold in the correct order, the stack is heated to a temperature of 201226253 (eg, between 80 ° C and 18 (TC), which is high enough to melt the resin. The molten resin is then distributed throughout the The entire model is filled with all possible gaps. Then, by lowering the temperature, the curing of the resin over time by the resin has the effect of firmly fixing all of the fibrous layers and the embedded segments 2, and at the same time The fibrous layer becomes firm and hard. In particular, the curing of the resin secures the exoskeleton fibrous layers 1a to the outermost layer of embedded segments 2. In addition, the curing of the resin causes the central fibers of the intermediate fibrous layers lb The fixing portion 8 is fixed to the center and the tail piece stacking portions 5 and 6 of the adjacent embedded segments 2 at the upper and lower surfaces. Finally, the resin is cured to make the intermediate fibers '·隹 layer 1 b and the like The outer fiber fixing portions 9 are fixed to each other and to the two exoskeleton fiber layers 1 a. : During the entire curing process, the I # preferably is slightly compressed together in 5 '' The same fiber layer 1 and segment 2 become close to each other in the interior of the model to improve the hardness and strength of the final product.

This is possible except as illustrated. For example, a different number of layers are used as a mixture of fixing members, and the additional adhesive in the 樽 type does not necessarily have to be an embodiment of the attachment hole, and the shape and size of the various components. Instead of using a curable resin, it is also placed in various layers and sheets. The mold is applied to the thread or it must be an embodiment variant. It is also possible to have layers and segments present during the period in which the other layers of the adhesive layer may be used on top of each other. The through hole. It is also possible to connect an object to the attachment hole in another way without using a threaded connection. In another embodiment variant, a plurality of relatively small through holes (perforations) may already be present in the plate-like embedded segments, i.e., before the plate-like embedded segments will be stacked with the fibrous layers. In this manner, after stacking with the individual fibrous layers, the fibrous layer material can not only adhere to the embedded segments, but can even penetrate slightly into the embedded segments. Thus 13 201226253 can create - even better connections between the fibrous layers and the descendant fragments. In addition, it should be noted that the embedded segments are not necessarily flat against the intermediate fiber layers on the entire surface of the intrusion segment. It is also possible to use inlaid segments which comprise a local thickening combined with an intermediate laminar fibrous layer' such intermediate laminar fibrous layers are in the same manner. The p-thickened area has complementary partial incisions. Thus, the plate-like embedded segments of the stack can be partially flattened directly against each other, and the intermediate fiber layer extends between the plate-like embedded segments for the remaining components. For example, the localized thickening of the embedded segments can be provided adjacent to or around the attachment aperture. Thus, according to the present invention, a very strong, rigid and lightweight load member is obtained 'the alternating stacking of the mourning segments individually covered and fixed by the fibrous layer material, even if t is placed at a high load or The same is true in extreme environments.
