Description

[0001] The present invention relates to a bracket for holding an electrical component adapted to be inserted from an open end of a bicycle into the fork stem of the bicycle, to a fork stem assembly comprising the bracket and the fork stem, and to a handlebar stem fixed to the fork stem and comprising the bracket.

[0002] As is known, a frame body (main body) of a bracket for holding an electrical component, such as a power supply for supplying an electric current, is arranged in the fork stem of a bicycle (e.g., JP 2005 - 138827 A). The conventional bracket includes a main body inserted from an upper portion of the fork stem, a stem cap in contact with the lower end of the fork stem, and a screw for screwing into the main body and penetrating the stem cap. The bracket is fixed relative to the fork stem by screwing the screw into the main body via the stem cap.

[0003] WO 2012 / 020 303 A2 discloses an exemplary bicycle frame with a head tube, a fork assembly, and a forked handlebar. A control cable is routed inside, with a cable guide arranged in the head tube, which has a groove in the forked handlebar that can accommodate part of the control cable.

[0004] DE 89 03 580 U1 discloses an exemplary bicycle handlebar, on the holder of which a niche is cut out as a seat for a microcomputer, which is connected to a signal generating device via lines running inside the frame, the fork and the handlebar holder.

[0005] Furthermore, a unit for adjusting the height of a suspension, which is arranged within a fork tube of a bicycle handlebar, is shown, for example, in DE 10 2011 001 517 B4.

[0006] Since there is no gap or only a very narrow gap between the outer peripheral surface of the main body and the inner peripheral surface of the fork stem, in a conventional bracket, for example, a cable connecting a switch on the handlebar and an electrically operated speed change device on a frame component cannot be inserted into the inside of the fork stem.

[0007] Therefore, it is an object of the present invention to enable a cable to be routed through the interior of a fork tube while using a bracket inserted into the fork tube.

[0008] The problem is solved by the subject matter of claims 1, 9, 13, 16, 17, and 19. Preferred embodiments are described in the dependent claims. According to the present invention, a bracket for holding an electrical component is provided, which bracket is adapted to be inserted into the fork tube of a bicycle from a first open end. The bracket comprises a tubular main body having a first end, a second end on the opposite side of the first end, and a receiving space for receiving the electrical component, which is arranged between the first end and the second end.The main body includes a boss portion formed at the first end and disposed at the first open end; and a gap enlarging portion configured and disposed such that a gap between the inner peripheral surface of the steerer tube and the outer peripheral surface of the main body is enlarged at the gap enlarging portion along the axial direction of the main body to be larger than at the other portions.

[0009] In the bracket described above, the gap enlargement part is configured and arranged so that when the bracket is installed in the fork stem, the gap between the inner peripheral surface of the fork stem and the outer peripheral surface of the main body is enlarged at the gap enlargement part along the axis direction of the main body to be larger than at the other parts. Thus, even when the bracket is inserted into the fork stem, a cable can be routed through the space between the gap enlargement part and the inner peripheral surface of the fork stem.

[0010] The attachment part is provided with a first slot that connects to the gap enlargement part. This allows a cable to be easily routed from outside the bracket through the first slot into the gap enlargement part.

[0011] The main body is provided with a second slot at the first end, which communicates with the receiving space, the gap enlargement part, and the first slot. Thus, even if the first end of the main body protrudes from the fork steerer tube at the first open end, a cable can be easily inserted into the gap enlargement part from outside the bracket by connecting the first slot to the gap enlargement part through the second slot.

[0012] Preferably, the electrical component comprises an electrical storage component. This allows the electrical storage component to be housed with an excellent external appearance. Advantageously, the electrical storage component comprises a secondary battery. This allows the rechargeable secondary battery to be housed with an excellent external appearance.

[0013] The receiving space may be arranged eccentrically toward the opposite side of the gap enlarging portion relative to the outer peripheral surface of the main body. In this case, even if a large receiving space is provided for the electrical component, a large gap enlarging portion can be formed.

[0014] Preferably, the gap-enlarging part is in the form of a groove. In this case, even with the gap-enlarging part formed, the bracket can easily engage with the inner peripheral surface of the fork tube. Thus, the bracket can be guided and inserted into the fork tube.

[0015] The main body may be provided with a third slot at the first end that communicates with the receiving space. This allows a cable to be easily inserted from outside the bracket through the third slot, the receiving space, and the second slot into the gap enlargement part.

[0016] Preferably, the attachment part is provided with a fourth slot that communicates with the third slot. Thus, a cable can be easily inserted into the gap enlargement part from outside the holder through the fourth slot, the third slot, the receiving space, and the second slot.

[0017] The third slot may be configured and arranged to be opposite the second slot in the radial direction of the main body, and the fourth slot may be configured and arranged to be aligned with the first slot in the radial direction of the main body. This allows a cable to be easily routed from outside the handlebar to the opposite side of the handlebar.

[0018] Preferably, the main body is provided at the second end with a threaded hole extending in the axial direction. The bracket may further comprise an engagement member engaging with a second open end of the bicycle on the opposite side of the first open end, and a screw to be screwed into the threaded hole and penetrating the engagement member. In this case, when the screw is screwed into the threaded hole, the main body is pulled toward the second open end side, so that a clamping force is exerted on the boss member and the engagement member from the first open end and the second open end, respectively, thereby fixing the main body with respect to the fork stem. Thus, the bracket rotatably holds the fork stem to a part of the bicycle frame serving as a head component.

[0019] The engagement component may be provided with a fifth slot that communicates with the interior of the fork tube. Thus, even with the engagement component present, a cable can be routed through the fifth slot from the interior of the fork tube to the exterior.

[0020] Preferably, the first open end is provided on the handlebar stem, which is attached to the fork tube, and the second open end may be provided on the fork tube. In this case, the main body can be easily inserted into the fork tube from the top of the fork tube.

[0021] The main body may be configured such that the first end is an open end, and the holder may further comprise a plug that is inserted into the main body from the first end to close the receiving space. In this case, if the first end of the main body is an open end for installing the electrical component in the receiving space, the open end may be closed with the plug.

[0022] According to another embodiment of the present invention, a bracket for holding an electrical component is provided, which bracket is adapted to be inserted into the fork stem of a bicycle from a first open end. The bracket includes a tubular main body having a first end, a second end on the opposite side of the first end, and a receiving space for receiving the electrical component, which is arranged between the first end and the second end. The main body includes a boss part formed at the first end and arranged at the first open end; and a gap enlarging part configured and arranged such that a gap between the inner peripheral surface of the fork stem and the outer peripheral surface of the main body is enlarged at the gap enlarging part along the axial direction of the main body to be larger than at the other parts.The main body includes a positioning part engaging with the handlebar stem for positioning the main body in the circumferential direction relative to the fork tube. This allows the movement of the main body in the circumferential direction relative to the handlebar stem to be restricted. Consequently, the movement of the main body in the circumferential direction relative to the fork tube to which the handlebar stem is fixed can be restricted.

[0023] The positioning part engages with a notch provided on the handlebar stem. This allows the notch, through which a cable can pass, to be used for positioning.

[0024] The positioning part can be provided on the attachment part. This allows the main body to be positioned without the need for a separate positioning component on the main body.

[0025] The positioning member may include two projections extending from the first slot or fourth slot. This allows the main body to be positioned using a simple structure.

[0026] According to the present invention, a fork stem assembly is provided, including a fork stem of a bicycle and a bracket for holding an electrical component inserted into the fork stem of the bicycle. A cable guide member for guiding a cable is formed between the inner peripheral surface of the fork stem and the outer peripheral surface of the bracket. In this fork stem assembly, the cable can be inserted into the fork stem via the cable guide member.

[0027] The steerer tube assembly bracket is a bracket as described above, with the cable guide part including the gap enlargement part. In this case, the cable guide part can be enlarged.

[0028] With the present invention, a cable can be easily routed through the interior of a fork tube.

The fork stem 12 is arranged such that its axis is coaxial with the axis X1 of the steering head 4.

[0031] The electrical storage component 20 is an example of an electrical component. The electrical storage component 20 includes at least one (e.g., two) secondary batteries 20a. The secondary battery 20a is provided on its upper part with a control substrate 20b for controlling the charging and discharging of the secondary battery 20a. The secondary battery 20a and the control substrate 20b are electrically connected to each other. The control substrate 20b is provided on its upper part with a connector 20c for electrically connecting a cable 32 to the control substrate 20b.

[0032] The bracket 14 can be inserted into the fork stem 12 from a first open end 8a of the bicycle while holding the secondary battery 20a. In the illustrated embodiment, the first open end 8a is provided on the handlebar stem 8. The handlebar stem 8 is fixed at one end thereof to the upper end of the fork stem 12, for example, with two screws 8c, and at its other end to the handlebar 6. A cable grommet 8b in the form of a slit-shaped notch portion is formed on the first open end 8a of the handlebar stem 8.

[0033] As in the Fig. 3, Fig. 4 and Fig. As shown in Fig. 5, the bracket 14 includes a tubular main body (bracket main body) that can be inserted into the fork stem 12, an engaging member 24, a bolt 26, and a plug 28. A cable guide part 34 for guiding cables 30 and 32 is formed between the inner peripheral surface 12a of the fork stem 12 and the main body 22. The cable 30 is, for example, a wire for connecting a switch (not shown) arranged on the handlebar 6 to a control unit CU, and the cable 32 is, for example, a wire for connecting the electric storage component 20 to the control unit CU. The control unit CU is configured to control an electrically powered switching device (not shown), an electrically powered suspension (not shown), or the like by utilizing the electric power of the electric storage component 20 in response to the command of the switch.

[0034] The main body 22 is a tubular member made of metal, such as aluminum. The main body 22 includes a first end 22a, a second end 22b on the opposite side of the first end 22a, and a receiving space 22c located between the first end 22a and the second end 22b for receiving the secondary battery 20a. The main body 22 is provided with a boss portion 36 to be disposed at the first open end 8a of the handlebar stem 8, and a gap enlarging portion 38 disposed on the outer peripheral surface 22d of the main body 22.

[0035] The first end 22a of the main body 22 is an open end with a circular opening, and the second end 22b is a closed end. At least a portion of the outer peripheral surface 22d of the main body 22 engages the inner peripheral surface 12a of the steerer tube 12. In the illustrated embodiment, the outer peripheral surface 22d engages the inner peripheral surface 12a of the steerer tube 12 on a side where the bracket 14 is inserted, i.e., on the side of the first end 22a.

[0036] As in the Fig. 1 and Fig. As can be seen in Fig. 3, the receiving space 20c is arranged eccentrically toward the opposite side to the gap enlarging part 38. More specifically, the receiving space 22c is configured and arranged to be a tubular space around an axis X2, which is closer to the opposite side to the gap enlarging part 38 than the axis X1. Fig. 3 shows a state in which the plug 28 has been removed.

[0037] As in Fig. As shown in Figure 5, the extension part 36 is formed at the first end 22a of the main body 22 such that the extension part 36 has a larger diameter than the other parts of the main body 22. The extension part 36 is provided with a first slot 36a that communicates with the gap enlarging part 38. If necessary, a spacer 42 can be mounted between the extension part 36 and the first open end 8a of the handlebar stem 8 for adjusting the position of the main body 22. The spacer 42 is C-shaped with a cutout portion.

[0038] The main body 22 is provided at the first end 22a with a second slot 22e that communicates with the receiving space 22c, the gap enlarging part 38, and the first slot 36a. The main body 22 is further provided at the first end 22a with a third slot 22f that communicates with the receiving space 22c. As shown in Fig. 1, the main body 22 is provided at the closed second end 22b with a threaded bore 22g extending along the axis X1.

[0039] The extension part 36 is provided with a fourth slot 36b that communicates with the third slot 22f. The third slot 22f is configured and arranged to oppose the second slot 22e in the radial direction of the main body 22. The fourth slot 36b is configured and arranged to align with the first slot 36a in the radial direction of the main body 22. The cutout portion of the C-shaped spacer 42 is configured and arranged to coincide with the third slot 22f and the fourth slot 36b.

[0040] In the illustrated embodiment, the main body 22 is inserted into the fork stem 12 such that the third slot 22f and the fourth slot 36b communicate with the cable grommet 8b of the handlebar stem 8. In this case, the boss 36 is provided with a positioning part 39 for positioning the main body 22 in a circumferential direction relative to the fork stem 12. The positioning part 39 includes two projections 39a. The two projections 39a extend from the fourth slot 36b toward the cable grommet 8b so as to engage with the cable grommet 8b. Thus, the movement of the main body 22 in the circumferential direction relative to the handlebar stem 8 is restricted. Consequently, the movement of the main body 22 in the circumferential direction relative to the fork stem 12 to which the handlebar stem 8 is fixed is restricted.

[0041] Alternatively, the main body 22 may be inserted into the fork shaft 12 such that the first slot 36a, the second slot 22e, and the gap enlarging member 38 communicate with the cable grommet 8b. In this case, as shown in Fig. 5 with two-dot chain lines, the positioning protrusions 139a are configured and arranged to extend from the first slot 36a. The positioning member may also be configured and arranged to engage with a clamping slot 8d of the handlebar stem 8. Further, the positioning member may be provided at any portion of the main body. For example, the positioning member may be configured and arranged to extend from the outer peripheral surface of the main body.

[0042] The gap enlarging member 38 forms part of the cable guide member 34 and is configured and arranged so that the cables 30 and 32 can be guided between the inner peripheral surface 12a of the steerer tube 12 and the main body 22. As shown in the Fig. 1 and Fig. As shown in Fig. 4, the gap enlarging part 38 is configured and arranged such that the gap between the inner peripheral surface 12a of the steerer tube 12 and the outer peripheral surface 22d of the main body 22 is enlarged at the gap enlarging part 38 along the axial direction of the main body 22 to be larger than at the other parts. In the illustrated embodiment, the gap enlarging part 38 is in the form of a groove formed in the outer peripheral surface 22d of the main body 22 and extending along the axial direction X1. The gap enlarging part 38 is provided at its central portion with an access part 38a that communicates with the receiving space 22c.

[0043] As in the Fig. 1 and Fig. 2, the engagement member 24 is typically a plate-shaped member that engages a second open end 12b of the bicycle, located opposite the first open end 8a. In the illustrated embodiment, the second open end 12b of the bicycle is provided on the fork stem 12. The engagement member 24 is provided with a fifth slot 24a that communicates with the interior of the fork stem 12, a head receiving portion 24b for receiving the head 26a of the bolt 26 threaded into the threaded bore 22g, and a through bore 24c through which a threaded portion 26b of the bolt 26 extends. The main body 22 is pulled toward the second open end 12b side when the screw 26 is screwed into the threaded hole 22g, so that the boss part 36 and the engagement member 24 are projected from the first open end 8a and 8b, respectively.the second open end 12b, a clamping force is exerted, by which the main body 22 is fixed relative to the fork stem 12. Thus, a pressure ring (not shown) arranged between the bearing unit 5a and the handlebar stem 8 is pressed into a non-fixed state by the handlebar stem 8, so that an inner ring of the bearing unit 5a is connected to the fork stem 12, which rotate together as a unit. In other words, the bracket 14 rotatably holds the fork stem 12 to a part of the bicycle frame serving as a head component. The so-called A-head head component is generally well known, and therefore a detailed description is omitted herein.

[0044] The plug 28 is inserted into the main body 22 from the opening of the first end 22a so as to close the receiving space 22c at the first end 22a of the main body 22. The plug 28 can be elastically mounted using an elastomer. Likewise, the plug 28 can be screwed into the receiving space 22c.

[0045] When the wires 30 and 32 are wired by an operator after the steerer tube assembly 10 having the above-described structure is mounted on the bicycle, the operator first leads the wire 30, which has been previously connected to a switch or the like mounted on the handlebar 6, from inside the handlebar 6 into the inside of the stem 8. Then, the wire 30 is led out of the wire grommet 8b of the stem 8 and passed through the fourth slot 36b and the third slot 22f. Subsequently, the wire 30 is passed through the second slot 22e and the first slot 36a to enter the gap enlarging part 38. On the other hand, the wire 32, which is connected to the connector 20c, is passed through the second slot 22e and the first slot 36a to enter the gap enlarging part 38.The operator then guides the cables 30 and 32, which have been passed through the gap enlarging part 38, through the fifth slot 24a so that they are guided along the bicycle frame and thus connected to the control unit CU.

[0046] With the steerer tube assembly 10 with the bracket 14, the cables 30 and 32 can be inserted into the interior of the steerer tube 12 because the cables 30 and 32 can be guided to the cable guide part 34, which includes the gap enlarging part 38, even when the bracket 14 is inserted into the steerer tube 12.

[0047] Although the cable guide member 34 including the gap enlarging member 38 was exemplified in the above-described embodiment as a groove, the present invention is not limited thereto. For example, the main body may be configured to have an outer peripheral surface having a circular cross-section with a partially flat portion when viewed from above along the axial direction, such that the cable guide member is formed between the flat portion and the inner peripheral surface of the steerer tube. Likewise, the cable guide member may be configured such that the outer diameter of the main body is set to have a circular cross-section larger than the inner diameter of the steerer tube to allow the cable to pass therethrough.

[0048] Although the cable guide member 34 is formed by the gap enlarging member 38 in the above-described embodiment, the present invention is not limited thereto. For example, the cable guide member may be formed by disposing an insertion tube through which the cable can be inserted between the outer peripheral surface of the main body and the inner peripheral surface of the steerer tube along the axial direction.

[0049] Although the electrical storage component 20 was cited as an example of the electrical component in the above-described embodiment, the electrical component is not limited to this. For example, the electrical component may be a connecting component for branching / joining the cables.

[0050] Although the secondary battery was cited as an example of the electrical storage component in the above-described embodiment, the present invention is not limited to this. For example, a primary battery or a capacitor with a larger capacity, such as an electric double-layer capacitor or the like, may be used as the electrical storage component.

[0051] Although in the above-described embodiment, a case in which the cable grommet 8b serves as a notch portion that allows the positioning member 39 to engage with the cable grommet 8b is exemplified, the present invention is not limited thereto. For example, the clamping slot 8d (see Fig. 3) of the handlebar stem 8, which is to clamp the fork shaft 12 by tightening the screws 8c, serve as the notch portion.

[0052] Although in the above-described embodiment, the positioning member 39 is arranged opposite the gap enlarging member 38, the present invention is not limited thereto. For example, as shown in Fig. 5 by the two-dot chain lines, a positioning member 139 having projections 139a may be arranged on the same side as the gap enlarging member 38. Preferably, the positioning member 139 includes two projections 139a extending from the first slot 36a to engage the notch portion, i.e., the cable grommet 8b. In this case, the cable guide member 34 is arranged on the side of the cable grommet 8b.
