Further, the terms and phrases used herein are not intended to be limiting; but rather, to provide an understandable description of the systems, apparatuses, and methods. While the specification concludes with claims defining the features of the systems, apparatuses, and methods that are regarded as novel, it is believed that the systems, apparatuses, and methods will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward.

(35) In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of embodiments is defined by the appended claims and their equivalents.

(36) Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the systems, apparatuses, and methods will not be described in detail or will be omitted so as not to obscure the relevant details of the systems, apparatuses, and methods.

(37) Before the systems, apparatuses, and methods are disclosed and described, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The terms “comprises,” “comprising,” or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The terms “a” or “an”, as used herein, are defined as one or more than one. The term “plurality,” as used herein, is defined as two or more than two. The term “another,” as used herein, is defined as at least a second or more. The description may use the terms “embodiment” or “embodiments,” which may each refer to one or more of the same or different embodiments.

(38) The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact (e.g., directly coupled). However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other (e.g., indirectly coupled).

(39) For the purposes of the description, a phrase in the form “A/B” or in the form “A and/or B” or in the form “at least one of A and B” means (A), (B), or (A and B), where A and B are variables indicating a particular object or attribute. When used, this phrase is intended to and is hereby defined as a choice of A or B or both A and B, which is similar to the phrase “and/or”. Where more than two variables are present in such a phrase, this phrase is hereby defined as including only one of the variables, any one of the variables, any combination of any of the variables, and all of the variables, for example, a phrase in the form “at least one of A, B, and C” means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

(40) Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The description may use perspective-based descriptions such as up/down, back/front, top/bottom, and proximal/distal. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of disclosed embodiments. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments; however, the order of description should not be construed to imply that these operations are order dependent.

(41) As used herein, the term “about” or “approximately” applies to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure. As used herein, the terms “substantial” and “substantially” means, when comparing various parts to one another, that the parts being compared are equal to or are so close enough in dimension that one skill in the art would consider the same. Substantial and substantially, as used herein, are not limited to a single dimension and specifically include a range of values for those parts being compared. The range of values, both above and below (e.g., “+/−” or greater/lesser or larger/smaller), includes a variance that one skilled in the art would know to be a reasonable tolerance for the parts mentioned.

(42) Herein various embodiments of the systems, apparatuses, and methods are described. In many of the different embodiments, features are similar. Therefore, to avoid redundancy, repetitive description of these similar features may not be made in some circumstances. It shall be understood, however, that description of a first-appearing feature applies to the later described similar feature and each respective description, therefore, is to be incorporated therein without such repetition.

(43) Described now are exemplary embodiments. Referring now to the figures of the drawings in detail and first, particularly to FIG. 1, there is shown a first exemplary embodiment of a line-fastening device 100 for fastening a hydraulic line 1 to a hydraulic component 2. The line-fastening device 100 comprises an extension 110, a separator 120, a fastening portion 130, and a connecting portion 140.

(44) The line-fastening device 100 has a passage, the free cross-section of which substantially corresponds to the free cross-section of the hydraulic line 1 to be fastened.

(45) The connecting portion 140 can comprise a first connecting piece that is introduced into the hydraulic line by a press fit in a way known to a person skilled in the art. The surface of the connecting piece comprises a barb-like surface contour that secures the connecting piece adequately against slipping out of the hydraulic line 1 at conventional working pressures.

(46) The fastening portion 130 comprises an outer wall, the outer wall 133 of which is adapted to the surface 201 of an inner wall of a support 200 of the hydraulic component 2, to which the hydraulic line 1 shall be connected. As a rule, the outer wall 133 has the form of a cylinder sleeve, wherein circumferential grooves are provided. Such fastening portions are known to a person skilled in the field of hydraulic line connections, namely from line-fastening devices for fastening lines to hydraulic bicycle caliper brakes and/or hydraulic bicycle disk brakes which, in contrast to here, have no extension but only the fastening portion 130 and the connecting portion 140.

(47) The extension 110 is connected to the fastening portion 130 through a separator 120, which is made as a predetermined breaking point. The separator 120 of the embodiment shown is made as a tapering, groove, or notch. The extension 110 can be separated from the fastening portion 130 with a suitable tool.

(48) The extension 110 also has a passage that is confined by an inner wall 111 of the extension 110. For filling the hydraulic line 1 and/or the hydraulic actuation device, the hydraulic line 1 and the hydraulic component (master/slave) can be filled at its other end through the extension 110. As soon as the system is filled and bled in a way known to a person skilled in the art, the operator can close and hydraulically seal the extension by introducing a seal 114 into the passage. For this purpose, a ball can be pressed into the passage, e.g., as the seal 114, such that the passage is closed by the press fit between ball and the inner wall 111. So that the seal 114 can be introduced more easily into the passage, a chamfer 112 can be provided at the beginning of the passage.

(49) The hydraulic line can comprise a reinforced or non-reinforced hydraulic line. A person skilled in the art knows the areas of use and will select the suitable hydraulic line.

(50) The hydraulic component 2 can be, e.g., a master device or a slave device of a hydraulic brake or coupling and/or another actuation device of a vehicle with handlebar steering. The hydraulic component 2 can also be an adapter that can be, e.g., part of a handlebar arrangement. Likewise, the hydraulic component 2 can be a connecting device for connecting two hydraulic line portions, such as, e.g., a line-coupling device.

(51) The hydraulic component 2 has a hydraulic line connection that is made as a threaded hole. The support 200 is screwed into the threaded hole and can be, e.g., a retaining screw. The support 200 has an inner wall 201, the form of which corresponds to the outer wall 133 of the fastening portion 130 of the line-fastening device 100.

(52) The outside diameter D.sub.A of the outer wall 113 of the extension 110 is larger than the internal diameter D.sub.I of the inner wall 201 of the support 200, as shown in FIG. 2. It is thus guaranteed that the line-connecting device 100 cannot be fastened by mistake to the support 200 without the extension 110 being cut off at the separator 120 beforehand, such that the fastening portion 130 can be inserted into the support 200.

(53) To fasten the fastening portion 130 in the support 200, a clamp 210 is initially inserted into the hydraulic connection of the hydraulic component 2. Then, the support 200 is pushed onto the line-fastening device 100, which is already connected to the hydraulic line via the connecting portion 140, which engages in the hydraulic line on the inside. Then, the support 200 is inserted into the hydraulic line connection with the line-fastening device, such that the clamp 210 encloses the fastening portion 130. After that, the support 200 is screwed into the hydraulic line connection such that the clamp 210 is compressed and forms a pressure-tight connection, as shown, e.g., in FIG. 19 by the example of an adapter that is arranged in a handlebar pipe 3.

(54) The hydraulic component, to which the hydraulic line connection prefilled with the hydraulic fluid shall be connected via the hydraulic line, also has to be delivered to the user in a prefilled condition so that a complex refilling and venting after the connection is avoided as completely as possible. For this purpose, the hydraulic component is filled with hydraulic fluid and bled in way known to a person skilled in the art. To avoid leakage of hydraulic fluid, the hydraulic component is closed with a sealing device 300 that can be designed as a plug, as shown in FIGS. 10 and 11.

(55) The sealing device 300 has a handle portion 301 that the operator can grip to be able to insert and remove the sealing device 300 into and out of the support 200. In respect of safety, the support 200 can, as with the fastening of the line-fastening device 100 in the support 200, be screwed into the thread of the hydraulic connection, such that the clamp 210 is compressed adequately to ensure safe sealing.

(56) The sealing device 300 has a shaft portion 302, the external diameter of which substantially corresponds to that of the hydraulic line 1 or the line-fastening device 100. A transitional portion 303 connects to the shaft portion 302 and changes into a conical portion 304, which engages in the hydraulic connection in accordance with a Luer cone and produces a sealing effect.

(57) FIGS. 14 and 15 show another exemplary embodiment, which corresponds substantially to the embodiment shown in FIGS. 1 to 13 and described in connection thereto. Therefore, only the differences with respect to the embodiment shown and described therein are described below and shown in FIGS. 14 and 15. Apart from that, reference is made to the description and the drawings of the first exemplary embodiment, wherein the same reference signs designate the same or corresponding components or features.

(58) In the embodiment of FIGS. 14 and 15, the fastening portion 130 has an outer wall 133, which is substantially cylindrical. The outer wall 113 of the extension 110 is octagonal in cross-section, but the outer circle thereof has a diameter that is larger than the diameter of the outer wall 133 of the fastening portion 130, which corresponds to the internal diameter D.sub.I of the support 200. Therefore, the distance D.sub.A of the parallel surfaces of the outer wall 113 corresponds to the internal diameter D.sub.I of the support 200. However, the largest dimension corresponds in cross-section to the outer circle of the octagon and is, thus, larger than the internal diameter D.sub.I of the support 200. Therefore, the extension 110 cannot be introduced into the support 200 and the operator will realize that he has to remove the extension 110 with the seal 114 arranged therein from the line-fastening device 100 to be able to then arrange it in the support 200 without the extension 110.

(59) FIGS. 16 and 17 show a further exemplary embodiment, which corresponds substantially to the exemplary embodiments shown in FIGS. 1 to 13 or 14 and 15 and described in connection therewith. Therefore, only the differences with respect to the embodiments shown and described therein are described below and shown in FIGS. 16 and 17. Apart from that, reference is made to the description and the drawings of the other embodiments, wherein the same reference signs designate the same or corresponding components or features.

(60) In this embodiment, the support 200 has an inner wall that is octagonal in cross-section. The internal diameter D.sub.I (measured from corner to opposite corner), i.e. the outer circle in cross-section, corresponds to the external diameter D.sub.A of the outer wall 113 of the extension 110. Due to the missing flat sections at the extension 110, the extension 110 of this exemplary embodiment cannot be introduced into the support 200 either and the operator realizes that he has to remove the extension 110 with the seal 114 arranged therein from the line-fastening device 100 to be able to then arrange it in the support 200 without extension 110. FIGS. 18 to 25 show a hydraulic line connection device and hydraulic component-fastening device according to an exemplary embodiment. The hydraulic line connection device and hydraulic component-fastening device comprises a hydraulic line connector 10, to which a hydraulic line 1 is fastened, as well as a hydraulic connector 20 and a hydraulic component fastener 30.

(61) The hydraulic line connector 10 is arranged inside a handlebar pipe 3, on which a handle pipe 4 can be provided. The hydraulic line connector 10 has a hydraulic line connection 11, which is connected to the hydraulic connector 20 via a connecting channel 12.

(62) The hydraulic component fastener 30 is arranged on the outside of the handlebar pipe. The master cylinder is attached to the hydraulic component fastener 30.

(63) The hydraulic connector 20 connects the hydraulic component fastener 30 to the hydraulic line connector 10. For this purpose, the hydraulic connector 20 engages in the hydraulic line connector 10, extends through a recess 8 in the handlebar pipe 3 and engages at the hydraulic component fastener 30.

(64) The recess 8 in the handlebar pipe 3 is designed as an oblong hole, such that the hydraulic component fastener 30 can be arranged at the handlebar pipe 3 in a desired setting via a distance that corresponds to the length of the oblong hole minus the dimensions (of the space required) of the hydraulic connector 20.

(65) The hydraulic component fastener 30 comprises a ring support 34, which extends around the handlebar pipe 3. On the side interior with respect to the vehicle, recesses 31 are arranged, in which a safety, e.g., an anti-rotation mechanism 32, can engage to secure the hydraulic component 2 mounted on the hydraulic component fastener 30 in a desired rotational position.

(66) The master cylinder has a pressure chamber 52, at the lower end of which, i.e., the end close to the handlebar pipe 3, a connecting channel 51 is provided, which is connected to the connecting channel 33 in the hydraulic component fastener 30. An equalizing tank 53 is provided on the side of the housing 5.

(67) The connecting channel 33 extends over the entire circumference of the ring support 34, such that the hydraulic component 2 can be mounted in any rotational position, wherein a hydraulic connection is ensured between the connecting channel 51 and the connecting channel 33.

(68) The hydraulic connector 20 comprises a bolt 22, in which a connecting channel 21 is provided. The connecting channel 21 is connected to the connecting channel 33 and a connecting channel 12 in the hydraulic line connector 10.

(69) The head of the bolt 22 is sealed against the hydraulic component fastener 30 by a seal 23, and the lower end of the bolt 22 is sealed against the hydraulic line connector 10 by a seal 24.

(70) The connecting channel 33 is sealed on its both sides by seals 35, 36, which are arranged in grooves that are formed on the surface of the hydraulic component fastener 30.

(71) The hydraulic component 2 has a master housing 5, which is arranged on the hydraulic component fastener 30 by a fastening portion 54, namely by a press fit, so as to allow, on the one hand, rotation about the handlebar and, on the other hand, sealing between the fastening portion 54 and the hydraulic component fastener 30 enclosed by the fastening portion via the seals 35, 36.

(72) Furthermore, a fastening arrangement 40 is provided, by which the axial position of the hydraulic component 2 can be secured on the handlebar. The fastening arrangement 40 comprises a bolt 41, which extends through a conical ring 43 and engages in the hydraulic line connector 10. The hydraulic line connector 10 comprises, on the side in which the bolt engages, a conical surface 44 that corresponds to the conical surface of the conical ring 43. A conical ring 42 is arranged on these conical surfaces. By screwing the bolt 41 into the thread of the hydraulic line connector 10, the conical ring 42 is braced radially outwards, such that the hydraulic line connector 10 is axially fixed in position by the frictional engagement.

(73) For the purpose of assembly, the hydraulic line connector 10 is first connected to the hydraulic line 1 and introduced into the handlebar pipe 3. Then, the hydraulic component fastener 30 is arranged on the outer side of the handlebar pipe 3 and fixed in a desired position by the hydraulic connector 20 by inserting it through the recess 8 in the handlebar pipe 3 and screwing it into the hydraulic line connector 10. The fastening arrangement 40 is tightened before or after this event. Thereafter, the hydraulic component 2 is arranged on the hydraulic component fastener 30 and turned in the desired position. Finally, the rotational position is secured by the anti-rotation mechanism 32 by tightening this mechanism.

(74) FIGS. 26 and 27 show a further exemplary embodiment, which corresponds substantially to the exemplary embodiments shown in FIGS. 18 to 25 and described in connection therewith. Therefore, only the differences with respect to the embodiments shown and described therein are described below and shown in FIGS. 26 and 27. Apart from that, reference is made to the description and the drawings of the other embodiments, wherein the same reference signs designate the same or corresponding components or features.

(75) In the embodiment shown in FIGS. 26 to 27, the recess is designed as a hole, the dimensions of which correspond to the dimensions of the hydraulic connector 20. Therefore, the hydraulic component fastener 30 can only be fastened to the handlebar pipe at a certain suitable position. However, in this embodiment, the fastening arrangement 40, as shown, can be omitted because the axial securement is effected by the hydraulic connector 20 that is arranged in the recess 8 and that prevents a displacement of the hydraulic component 2 in the axial direction. As a result, this embodiment can be formed more easily.

(76) FIGS. 28 to 30 show a further exemplary embodiment, which corresponds substantially to the embodiments of the invention shown in FIGS. 18 to 25 or 26 and 27 and described in connection therewith. Therefore, only the differences with respect to the embodiments shown and described therein are described below and shown in FIGS. 28 to 30. Apart from that, reference is made to the description and the drawings of the other embodiments, wherein the same reference signs designate the same or corresponding components or features.

(77) In the exemplary embodiment, which is shown in FIGS. 28 to 30, the anti-rotation mechanism 32 is arranged on the side of the hydraulic component fastener 30 that is opposite to the pressure chamber 52. Furthermore, a seal 38 is arranged in a region of the connecting channel 33, which extends over about 270° of the circumference. The advantage of this embodiment is that the sealing effect is enhanced when the anti-rotation mechanism 32 is tightened again after the setting of the desired rotational angle of the cylinder.

(78) In this embodiment, the recess can be designed in accordance with the embodiment of FIGS. 26 to 27, and, therefore, the fastening arrangement 40 can be omitted.

(79) FIG. 31 shows a further exemplary embodiment, which corresponds substantially to the exemplary embodiments shown in FIGS. 18 to 25 or 26 and 27 or 28 to 30 and described in connection therewith. Therefore, only the differences with respect to the embodiments shown and described therein are described below and shown in FIG. 31. Apart from that, reference is made to the description and the drawings of the other embodiments, wherein the same reference signs designate the same or corresponding components or features.

(80) In this embodiment, the hydraulic component 2 is pushed onto the hydraulic component fastener 30 until it laterally touches a stop 37. On the side opposite to the stop 37, a clamp ring 60 with an internal thread 61 is then screwed onto an external thread 39 formed on the hydraulic component fastener 30 so as to brace the hydraulic component 2 between the stop 37 and the clamp ring 60.

(81) FIG. 32 shows a further exemplary embodiment, which corresponds substantially to the exemplary embodiments shown in FIGS. 18 to 25 or 26 and 27 or 28 to 30 or 31 and described in connection therewith. Therefore, only the differences with respect to the embodiments shown and described therein are described below and shown in FIG. 32. Apart from that, reference is made to the description and the drawings of the other embodiments, wherein the same reference signs designate the same or corresponding components or features.

(82) In this embodiment, the seals 35 and 36 are made as squeezing seals that are arranged on both sides of the hydraulic component fastener 30. On the right-hand side, the housing 5 has a stop 55, which presses against the right-hand seal 36, which can be received in an optional groove 57, which is formed in the housing 5. On the left-hand side, the housing 5 has an external thread 56 on which a clamp ring 60 can be screwed by an internal thread 61, the clamp ring 60 pressing the left-hand seal 35 against the housing 5 and the hydraulic component fastener 30. When the clamp ring 60 is tightened, the seals 35, 36 are squeezed and expand radially outwards so as to achieve sufficient sealing for the operation of the hydraulic component 2.

(83) For the assembly, the clamp ring 60 with the seal 35 is initially pushed onto the handlebar pipe 3. Then, the hydraulic component fastener 30 is mounted on the handlebar pipe 3. Thereafter, the hydraulic component 2 with the seal 36 is pushed onto the handlebar pipe 3 and arranged on the hydraulic component fastener 30. Then, the clamp ring 60 can be tightened after the desired rotational position was set.

(84) The embodiments of FIGS. 31 and 32 show the hydraulic line connector 10 and the hydraulic line connection 11, in which the line-fastening device 100, as shown, e.g., in FIG. 19 or FIG. 29, can be arranged for connection to the hydraulic line 1.
