DETAILED DESCRIPTION OF EMBODIMENTS
(23) Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
(24) Referring initially to
(25) As used herein to describe the above embodiment(s), the following directional terms upper, lower, forward, rearward, above, downward, vertical, horizontal, below and transverse as well as any other similar directional terms refer to those directions of a bicycle equipped with the bicycle component control device. Accordingly, these terms, as utilized to describe the bicycle component control device should be interpreted relative to a bicycle equipped with the bicycle component control device as used in the normal riding position on a horizontal surface in an upright position. Finally, terms of degree such as substantially, about and approximately as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed.

(30) The first and second bracket parts 50 and 52 are further configured relative to each other such that a connecting seam 56 is formed on the exterior surface of the bracket 20. In this first embodiment, the connecting seam 56 is formed between the first and second bracket parts 50 and 52 such that the connecting seam 56 separates the bracket 20 along the mounting surface 34, the upper surface 36, the lower surface 38 and the free end 44. However, as will be apparent from the later embodiments, the connecting seam 56 can have other configurations. For the purpose of strength and durability, the connecting seam 56 extends along at least three of mounting surface 34, the upper surface 36, the lower surface 38, the first side surface 40 and the second side surface 42.
(31) In the first illustrated embodiment, the first and second bracket parts 50 and 52 are each made of a rigid, hard plastic material. Preferably, as illustrated, the first and second bracket parts 50 and 52 are formed by injection molding. Thus, the first and second bracket parts 50 and 52 are injection molded parts in the illustrated embodiment. More preferably, each of the first and second bracket parts 50 and 52 is formed using a draw molding machine using two molds or dies such that the first and second bracket parts 50 and 52 are formed without hidden surfaces. The draw direction refers to the direction in which the two molds or dies will separate to release from the bracket part 50 or 52 from the two molds or dies. The draw direction is also called a line of draw. In the context of injection molded parts, the term hidden surface refers to a surface of the injection molded part that cannot be seen while viewing the injection molded part in the draw direction. These hidden surfaces of the injection molded parts are often formed using slides that move into a cavity perpendicular to the draw direction for creating undercuts or overhanging features. Thus, as illustrated, the first and second bracket parts 50 and 52 are injection molded parts that have no hidden surfaces with respect to the draw direction. In this way, the molds or dies can be relatively simple, and the bracket part 50 or 52 can be easily ejected from the molds or dies.
(32) In the illustrated embodiment, the first and second bracket parts 50 and 52 are mirror images of each other, except that the first bracket part 50 has an interior face 60 that has a pair of blind bores 62 for threadedly receiving a pair of fasteners or screws 64, respectively, while the second bracket part 52 has a pair of stepped through bores 66 for receiving the fasteners 64 therethrough. Since the through bores 66 are stepped, the head of the fasteners 64 are recessed from the exterior surface of the second bracket part 52. Thus, the first and second bracket parts 50 and 52 are non-movably fixed to each other by the fasteners 64. Of course, other types of fastening arrangements can be used to non-movably fix the first and second bracket parts 50 and 52 together as needed and/or desired.
(33) In the first illustrated embodiment, the first bracket part 50 has a pair of support portions 70 and 72 that are configured and arranged to contact and support a first side of the bicycle component operating unit 24. Likewise, the second bracket part 52 has a pair of support portions 74 and 76 that are configured and arranged to contact and support a second side of the bicycle component operating unit 24. In the first illustrated embodiment, the support portions 70, 72, 74 and 76 constitute shaft engagement portions of the bracket 20.
(34) In the first illustrated embodiment, the first bracket part 50 has a first pivot hole 80 and the second bracket part 52 has a second pivot hole 82. The first and second pivot holes 80 and 82 receive a pivot pin 84 that defines the pivot axis A1. The pivot pin 84 pivotally supports the operating member 26 to the bracket 20 for movement in a direction B1 (
(35) The clamp 22 is a conventional handlebar clamp that is often used for road style shifters. In the first illustrated embodiment, the clamp 22 is sandwiched between the first and second bracket parts 50 and 52. In particular, the first and second bracket parts 50 and 52 mate together to form the clamp receiving recess 34a, as mentioned above, and a bolt receiving recess 86.
(36) In the first illustrated embodiment, the bicycle component operating unit 24 is a conventional mechanical shifting unit that pulls or releases a shift cable C1 (
(37) It will be apparent from this disclosure that any type of mechanical shifting unit can be used with the bracket 20 by reconfiguring the interior space 54 to match the configuration of the mechanical shifting unit. Thus the bicycle component operating unit 24 will not be discussed in further detail herein.

(42) Here, the bracket 420 includes a first bracket part 450 and a second bracket part 452. The first and second bracket parts 450 and 452 are separate pieces from each other, and mate together to define an interior space 454. The first and second bracket parts 450 and 452 are non-movably fixed to each other by a pair of fasteners or screws 464. The first and second bracket parts 450 and 452 are further configured relative to each other such that a longitudinal connecting seam 456 (i.e., the outline of the interior face 460) is formed on the exterior surface of the bracket 420 as seen in
(43) In this fifth embodiment, the first and second bracket parts 450 and 452 are further configured relative to each other to accommodate and support a hydraulic brake unit 424A and a mechanical shifting unit 424B. The hydraulic brake unit 424A is configured to operate a hydraulic brake device (not shown). The electric control unit 424B is configured to operate a bicycle electric device (not shown). Since the first and second bracket parts 450 and 452 can be configured to accommodate and support any hydraulic brake unit and any mechanical shifting unit, the hydraulic brake unit 424A and the mechanical shifting unit 424B will not be discussed and/or illustrated in detail herein. In other words, although the interior space 454 of the bracket 420 is different, the bracket 420 separates into two pieces in basically the same manner as the bracket 20, discussed above. Thus, each of the hydraulic brake unit 424A and the mechanical shifting unit 424B constitutes a bicycle component operating unit that is disposed in the interior space 454 of the bracket 420.
(44) The hydraulic brake unit 424A includes an operating member or brake lever 426 that protrudes toward outside of the interior space 454 of the bracket 420. The hydraulic brake unit 424A includes a master cylinder MC and a piston member P. The master cylinder MC is disposed inside of the gripping portion 430 of the bracket 420. The piston member P is movably arranged in the master cylinder MC. In particular, the piston member P is moved toward the mounting surface 434 of the bracket 420 in response to operation of the operating member 426. The master cylinder MC of the hydraulic brake unit 424A is located rearward of the pivot axis A1 of the operating member 426 while the bicycle component control device 410 is in an installed position as seen in
(45) Referring now to
(46) Here, the bracket 520 includes a first bracket part 550 and a second bracket part 552. The first and second bracket parts 550 and 552 are separate pieces from each other, and mate together to define an interior space 554. The first and second bracket parts 550 and 552 are non-movably fixed to each other by a pair of fasteners or screws 564. The first and second bracket parts 550 and 552 are further configured relative to each other such that a longitudinal connecting seam 556 (i.e., the outline of the interior face 560) is formed on the exterior surface of the bracket 520 as seen in
(47) In this sixth embodiment, the first and second bracket parts 550 and 552 are further configured relative to each other to accommodate and support a hydraulic brake unit 524A and an electric control unit 524B that can be either an electric shift unit or a non-shifting control unit. The hydraulic brake unit 524A is configured to operate a hydraulic brake device (not shown). The electric control unit 524B is configured to operate a bicycle electric device (ED), Since the first and second bracket parts 550 and 552 can be configured to accommodate and support any hydraulic brake unit and any electric control unit, the hydraulic brake unit 524A and the electric control unit 524B will not be discussed and/or illustrated in detail herein. In other words, although the interior space 554 of the bracket 520 is different, the bracket 520 separates into two pieces in basically the same manner as the bracket 20, discussed above. Thus, each of the hydraulic brake unit 524A and the electric control unit 524B constitutes a bicycle component operating unit that is disposed in the interior space 554 of the bracket 520.
(48) The hydraulic brake unit 524A includes an operating member or brake lever 526 that protrudes toward outside of the interior space 554 of the bracket 520. The hydraulic brake unit 524A includes a master cylinder MC and a piston member P. The master cylinder MC is disposed inside of the gripping portion 530 of the bracket 520. The piston member P is movably arranged in the master cylinder MC. In particular, the piston member P is moved toward the mounting surface 534 of the bracket 520 in response to operation of the operating member 526. The master cylinder MC of the hydraulic brake unit 524A is located rearward of the pivot axis A1 of the operating member 526 while the bicycle component control device 510 is in an installed position as seen in
(49) While only selected embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. For example, the size, shape, location or orientation of the connecting seam can be changed so long as the connecting seam extends along at least three of the mounting surface, the upper surface, the lower surface, the first side surface and the second side surface. For example, in the fifth and sixth embodiments, the bracket parts can be divides such that the connecting seam is similar to any one of the second, third or fourth embodiments. In the case of the fourth embodiment, the connecting seam can separate the bracket along one of the first and second side surfaces, one of the upper and lower surfaces, and the mounting surface as needed and/or desired. Thus, the foregoing descriptions of the embodiments according to the present invention are provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
