Description of the Invention: [Technical Field] The present invention relates to a method for connecting bicycle frame components, in particular to a bicycle frame component of a fiber-reinforced plastic material, such as carbon fiber; further, the present invention relates to an implementation A combination of the above methods. [Prior Art] 〇 Especially in road sports cars or race cars or in other types of bicycle frames ‘have tried to be designed to be lighter and lighter. In addition to the structure, the materials used are decisively important. Therefore, the frame of reinforced fiber plastic, especially carbon fiber, has been developed for several times. Difficulties lie in the connection of individual bicycle frame components 'e.g., the tube of the upper and lower f and the head of the vehicle' or the combination of the upper and the seat tube. The other aspect is the connection between the five-rail down tube and the = tube. - The connection of the bicycle frame components, the f-type uses different "joints". These frame tubes and "joints" are manufactured separately, and then the frame tube is inserted into the thin tube to connect these soap holder tubes. At the beginning. These joints are conventionally constructed by a type of _, which is money _, and the connection between these joints and the two frame elements is achieved by means of an adhesive. In order to be able to assemble the joints and self-trailer frame components, the internal diameter of these joints must be greater than the outer diameter of some bicycle frame components. In order to connect these components, the above components and connectors must be filled with an adhesive. In particular, the last frame tube 2 is inserted into a joint, and the tube and/or the joint must be forced or _ in order to be able to combine. Because of these (four) and/or the area where these 1272205 are in close contact or contact, because the bonding zone is not only adjacent but also

A more convenient way is to laminate the material, in particular at the junction of the two bicycle frame components, to completely wrap the two frame components. In particular, the material stack can be formed by repeatedly winding the frame members to be joined, and the material stack is pushed outwardly relatively thin, and the implementation area is the intersection of the bicycle frame components to be joined. Therefore, a very regular and stable process is produced and the structure of the force is improved. Furthermore, the thickness of the edge region of the material laminate is substantially the same as the thickness of the edge region of the bicycle frame member to be joined. Then, according to the invention, the thus prepared joint zone and the bicycle frame component are individually placed in the pressure chamber, and the optimum sound force applied to the pressure chamber is at least 3 bars (3xl 〇 5 Basca (pascai) )), especially good is at least 4 bar (4xl05 Baska). The material bonding layer is pressed against the bicycle frame components by the pressure generated by the air. Further, the joining medium provided to the material bonding layer or the direction of the filament surface to be joined is extruded and infiltrated into the voids of the fibers or the fibers. As such, the subtractive layer contains the risk of air and further extrudes excess linker. Therefore, it is possible to manufacture a very stable and firm connection, and a further advantage is that the material required for the joint prepared by the pre-manufacture and connected by the adhesive is further required to require no additional __. The result is a reduction in weight. If several layers of material are provided, the layers of these materials are squeezed together to create a very strong fit. According to the method of the present invention, before the pressure is applied, the joint of the two elements is placed in the pressure chamber or surrounded by pressure before 1272205, and the material bonding layer is surrounded by an elastic bushing. . Preferably, the liner is in contact with the layer of fibrous material and is disposed to completely surround the bond zone and the entire stack of materials. Or, the bushing is securely sealed to the joint area on the outside of the bicycle frame member. The benefit of using such a bushing is that when pressure acts in the pressure chamber, as the pressure increases, air does not enter the material layer and the fibers separate the bicycle frame components to be joined. This is especially important for high-strength fibers because they will return to their original position at the bend in the combined state. Good farming, the bushing should be as thin as possible. If desired, the liner may be a metal foil with a thickness of a few microcentimeter (μm). In this case, if necessary, it is sufficient to form a bushing with a metal foil surrounding the bonding material layer. Preferably, the material of these bushings or metal (4) is not combined with the bonding agent (special = grease). Therefore, a set of bushings or coated plastics 1 . Le’s this new look is repeated. In order to achieve this goal, the county is cut so that it can be surrounded by the bushings. The secret side is dense: or _ to seal. Let _ material, (4) be - fresh material fiber combined with the material of the stalker / wrapped in the joint part. In particular, the strip, and the mouth material are at least, and part of the 疋, 4 is the best m is the joint zone of the brake car (four), or can be borrowed by the winding method ==== in the shape, the joint If the material is firmly combined, then the above method can be achieved with %t, t, and right unidirectional fibers, because these fibers can be arranged in the direction of the main force by the arrangement of the bonding materials through 1272205. Improve the connection and connect the bicycle frame components during the month when the bicycle frame components are completely hardened. Therefore, it is possible to promote a better connection between the connecting agent (for example, resin) and the bicycle frame components. After the bonding method is completed, the excess connection is completed. The agent may be removed, provided that a subsequent treatment is required. Further, the invention relates to a bonding device that is adapted to perform the method previously described. To form a pressure chamber to accommodate the bicycles The frame component, which is composed of two (preferably two) air chambers. The two air chambers can be connected by a connector (for example, a clamping device, a locking device and a tension device). The connection is such that the connection faces are substantially sealed. Among these connection faces, a sealing material or a seal can be used, and these connection faces are made up of two recording pieces or a chamber piece and a bicycle frame. In accordance with the present invention, the more the recesses, the bicycle frame members are placed from the recesses, and when the pressure chambers are closed, the recesses are used to establish the bicycle-rotating elements and preferably establish a solid relationship. There is a benefit that the whole is placed in the pressure chamber, only the frame does not have to be clamped by a base, and these joint areas are weakened by a '7, the medium is filled with the pressure chamber. The connection of the holy force makes the pressurized oxygen or the other particularly suitable. An elastic jacket is provided in the pressure chamber to connect the bonded regions of the components and seal the joint. One percent is to be connected according to the method of the present invention, and the knot can be improved by (4) 1272205. Similarly, the opening or recess 16 can be omitted, and the end face contour of the upper tube 12 is aligned with the direction of the seat tube 1 , such that the end surface of the upper tube 12 is in contact with the outer circumference of the seat tube 10. In particular, , the above two The manner of energy connection is an advantageous choice and the generation of strain can be avoided. In the next step, a laminate 18 of fibrous material is used in the bonding zone 2, in other words, at least around the junction 14. This fibrous material stack The layer 18 is preferably constructed of a unidirectional bonding material, and the joints 14 in the bonding zone 2 are preferably wound one or more times. Thus, as shown in the third figure, the fibrous material laminate 18 Preferably, it is wound around the entire circumference of the two bicycle frame members 10, 12. The individual fibers of the fibrous material laminate 18 are preferably such that the fibers cross each other as well, particularly to form a diamond-shaped pattern. In this step, the resin-impregnated bonding material is surrounded by a bushing 22 (refer to the fourth drawing). This bushing 22 is composed of an elastic material such as silicone. This bushing 22 is arranged over the entire bonding zone 2, in particular - over the entire area surrounding the fibrous material stack 18. In order to achieve this, the bushing 22 is composed of a plurality of sections or a τ-shaped elongated hole 24. Since the bushing 22 is elastic, the bushing 22 can be connected from the two bicycle frame components. Install the back of the upper tubes 10, 12 (refer to the fourth figure). For example, in the range of the T-shaped elongated hole 24, it is not covered with the bushing 22, or it is sealed with silicone rubber. Again, a seal can be applied at the edge 26 (representing the transition zone between the liner 22 and the seat tube, upper tubes 1 , 12), which can also be achieved, for example, by silicone. 11 1272205 is to connect the seat tube and the upper tube 10, 12, after the sleeve is sealed and sealed, as shown in the fourth figure, is placed in the pressure chamber 28 (refer to the seventh figure). A preferred embodiment of a pressure chamber 28 comprises two plenum elements 3, 40, which are constructed substantially in a mirrored manner (cf. Fig. 5) (i.e., the pressure chamber 28 is constructed of two upper and lower mirrors). The plenum element 3〇 contains an internal space 32 which is formed by the arrangement of two plenum elements 3, 40 on each other, as seen in the seventh diagram. The space 32 encloses the liner 22 so that a gap is formed between the outside of the liner 22 and the interior of the space 32 which is used to pressurize the gas. In order to accommodate the tubular seat tube, upper tube 1 〇, 12 and circular intersection, this plenum element 30 comprises a semi-circular recess 34. The inner side 36 of these semi-circular recesses 34 has a semi-annular structure corresponding to each of the chamber members. These semi-annular structures are slightly larger than the outer dimensions of the seat tube and the upper tubes 10, 12, when the pressure chamber 28 is closed, the inside of the recess 34 36 encloses the seat tube and the upper tube 10, 12 (refer to the seventh figure). A sealing material or sealant (e.g., silicone) is used between the inner side 36 of the semi-circular recess 34 and the outer side 38 of the bicycle frame members 10,12. After the two bicycle frame member seat tubes to be combined, the upper tubes 1 and 12 are placed in the air chamber member 3G shown in Fig. 5, as shown in Fig. 6, the second air is supplied to the element 4 ( Referring to the seventh figure) placed on the first chamber element plus, the surfaces 42 that are in contact with each other are preferably sealed via a sealing material or a sealant. In order for the two plenum elements 30, 40 to be securely interconnected, there may be connecting elements not shown in the drawings, for example, side-by-side, joint or the like. Therefore, by closing the pressure chamber 28, an outer sealed space 32 is formed inside, for example, the force chamber 28, and two seat tubes, the upper tubes 1 and 12, which are to be formed, are placed in this seal. The empty 12 1272205 is simultaneously surrounded by an elastic bushing 22. The four spaces 32 are overpressured via a pressure connection point. Therefore, by virtue of its elasticity, the lining = skin = shrink and press on the fibrous material laminate 18. Thus, the excess resin and gas material laminate 18 is pressed out, preferably before the secret of this embodiment. This wire 22 has been transferred to the fourth layer 18, particularly in the ''Ό σ region 20'. After a period of time (depending on the material), the two chamber components 3G, 4G are separated again and again. Immediately after the completion of the composition of the material, the material is only slightly pure, and the excess resin inside or outside the tube is removed. Then = ‘for example, grinding, painting and the like. "Can be set up as a simple bracket 48, 50 can be connected to the tube 52 and the wire 54 on the ttl. For example, in order to pressurize the car and add 4fi, the entire frame 46 will put pressure on it. Room 28.
