2. Background Information
Bicycling is becoming an increasingly more popular form of recreation as well as a means of transportation. Moreover, bicycling has become a very popular competitive sport for both amateurs and professionals. Whether the bicycle is used for recreation, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. Additionally, bicycles are constantly being designed so as to be more ergonomic and user friendly. In particular, various additional accessories and/or improved components have been developed in recent years to assist the rider in operating the various components of the bicycle and/or to make the riding experience more convenient and enjoyable for the rider.
For example, the shifting units of a bicycle are often located at the ends of the handlebar such that the rider can easily perform a shifting operation without significantly changing the position of the rider's hands. However, this positioning of the shifting units makes it difficult to determine the current gear position for the rider. Specifically, the shifting units typically will have some sort of gear position indicator, in which case the rider must look towards the sides (ends) of the handlebar in order to determine the current gear positions. This arrangement is inconvenient for the rider.
Accordingly, gear indicators have been developed which are mounted on a center portion of the bicycle handlebar so that the rider does not have to take his or her eyes off of the road to determine the current gear position. For example, U.S. Pat. No. 6,331,089 discloses such gear indicators. Other accessories and/or components such as bicycle computers and/or lights and the like have also been mounted to the center of the handlebar for the rider's convenience in recent years. These devices are usually clamped onto the bicycle handlebar using a conventional C-shaped clamping member. While all of these devices work relatively well, it can be difficult and/or complicated to install such accessories and/or components on the bicycle, especially on different sized handlebars. Moreover, these typical accessories and/or components can be relatively complicated and expensive to manufacture and assemble, especially when it is desirable to make these devices compatible with different sized handlebars.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved mountable bicycle structure. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
One object of the present invention is to provide a mountable bicycle structure that can be easily and reliably mounted on a tubular member.
Another object of the present invention is to provide a mountable bicycle structure that can be easily and reliably mounted on different sized tubular members such as different sized handlebars, and which can be used to support several different components on the different sized handlebars.
Another object of the present invention is to provide a mountable bicycle structure that can be easily and rigidly secured on a center portion of the handlebar for easy viewing of a component that is coupled thereto.
Another object of the present invention is to provide a mountable bicycle structure that is strong, yet relatively lightweight.
Yet another object of the present invention is to provide a mountable bicycle structure that has a simple structure with relatively few separate parts.
Still another object of the present invention is to provide a mountable bicycle structure that that is relatively simple and inexpensive to manufacture using conventional manufacturing techniques.
The foregoing objects can basically be attained by providing a mountable bicycle structure that includes a component support portion, a tubular clamping portion, a tightening structure and an adapter member. The component support portion is configured and arranged to support a bicycle component. The tubular clamping portion is coupled to the component support portion. The tubular clamping portion has a split ring configuration with an attachment slot, a first end section, a second end section and an inner surface extending between the first and second end sections to define an adjustable inner diameter that extends around a center axis. The tightening structure is coupled to the first and second end sections of the tubular clamping portion to selectively reduce the adjustable inner diameter of the tubular clamping portion. The adapter member has a split ring configuration with an outer surface removably arranged on the inner surface of the tubular clamping portion. The adapter member has a pair of free ends with a split therebetween. The inner surface of the tubular clamping portion and the adapter member are arranged and configured to align the split of the adapter member with the attachment slot.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention 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 of 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.

Because the bicycle 10 is basically conventional, the bicycle 10 will not be discussed and/or illustrated in detail herein, except as related to the present invention. Moreover, it will be apparent to those skilled in the art from this disclosure that various modifications can be made to the bicycle 10 and/or the various components of the bicycle 10 without departing from the scope of the present invention described and illustrated herein.
The display device 13 is actuated by a pair of shifting units 16 and 18 that are mounted at opposite ends of the handlebar 14 in a conventional manner. Specifically, the shifting units 16 and 18 are operatively coupled to gear indicator displays 11a and 11b of the display device 13 via a pair of indicator cables 17 and 19, respectively, such that the display device 13 indicates appropriate gear positions of the drive train in a conventional manner. The shifting units 16 and 18 also have shift cables extending therefrom to control the derailleurs of the drive train of the bicycle 10 in a conventional manner.
The shifting units 16 and 18 are well known in the bicycle art, and are not critical to the present invention. Thus, the shifting units 16 and 18 will not be discussed and/or illustrated in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that different types of shifting units can be used with the display device 13. Similarly, the display device 13 is well known in the bicycle art, except the manner in which the display device 13 is supported on the handlebar 14 by the mounting member 12. For the sake of convenience, the display device 13 and the shifting units 16 and 18 are preferably configured in accordance with U.S. Pat. No. 6,331,089. In other words, for the sake of brevity, the display device 13 and the shifting units 16 and 18 will only be discussed and illustrated herein as needed to understand the present invention.
However, it will be apparent to those skilled in the art that the display device 13 and the shifting units 16 and 18 can be modified as needed and/or desired, as long as the display device 13 and the shifting units 16 and 18 are compatible with each other. For example, the display device 13 and the shifting units 16 and 18 can be modified for a different number of gear shifting positions. The number of gear shifting positions or stages will depend upon the number of gears or sprockets used in the bicycle's transmission. In other words, while the gear indicator displays 11a and 11b and shifting units 16 and 18 are illustrated as three-stage and six-stage units, respectively, it will be apparent to those skilled in the art from this disclosure that additional stages or fewer stages can be provided as needed and/or desired.

Preferably, the component support portion 20, the first tubular clamping portion 22 and the second tubular clamping portion 24 are each constructed of a lightweight, rigid material such as hard plastic, synthetic resin, metallic material or any other material that is well known in the bicycle art. More specifically, the component support portion 20, the first tubular clamping portion 22 and the second tubular clamping portion 24 are preferably integrally formed together as a one-piece, unitary member by casting a lightweight material such as plastic or lightweight metal alloy. In any case, the component support portion 20 is preferably non-movably fixedly coupled with the first and second tubular clamping portions 22 and 24.
One of the adapter members 26 is preferably mounted to each tubular clamping portion 22 and 24 to contact the outside surface of the handlebar 14 when the tubular clamping portion 22 and 24 are clamped onto the handlebar 14. Accordingly, when the fasteners 28 are tightened to non-movably clamp the tubular clamping portions 22 and 24 onto the handlebar 14, the component support portion 20 is preferably non-movably supported on the handlebar 14. In this embodiment, the component support portion 20 is arranged and configured to support the gear indicator displays 11a and 1b of the display device 13 on the handlebar 14. Of course, it will be apparent to those skilled in the art from this disclosure that various other components can be supported in accordance with the present invention, as needed and/or desired. For example, the a cycle computer, lamps and/or the display device 13 can be supported in accordance with the present invention as discussed below with reference to other embodiments of the present invention.
The first and second tubular clamping portions 22 and 24 are substantially identical to each other, except that they are mirror images of each other. Accordingly, only one of the tubular clamping portions 22 and 24 (i.e., the first tubular clamping portion 22) will be discussed in detail herein. However, it should be apparent to those skilled in the art from this disclosure that the descriptions of the first tubular clamping potion 22 also apply to the second tubular clamping portion 24, except as explained and illustrated herein. The tubular clamping portion 22 is basically a substantially C-shaped member that includes a first end section 32, a second (free) end section 34 and a curved section 36 extending around a center axis X between the first and second end sections 32 and 34 to form a split ring configuration with an attachment slot 38. A connecting section 40 extends between the component support portion 20 and the tubular clamping portion 22 (i.e., from both the first end section 32 and the curved section 36 to the component support portion 20).
The first end section 32 preferably includes an unthreaded blind bore 32a and a nut receiving opening 32b. The blind bore 32a is configured to rotatably receive the fastener 28 therein, while the nut receiving opening 32b is configured to non-rotatably receive the nut 30 therein to prevent rotation of the nut 30. The second (free) end section 34 preferably includes an unthreaded through bore 34a and a head receiving recess 34b. The through bore 34a is configured to rotatably receive the fastener 28 therethrough, while the recess 34b is configured to rotatably receive the head of the fastener 28.
Thus, when one of the fasteners 28 is threaded into the nut 30 that is located in the nut receiving opening 32b, the end sections 32 and 34 will move toward each other to decrease the effective inner diameter of the curved section 36 in a relatively conventional manner. In other words, an inner diameter D3 of the curved section 36 is adjustable. Accordingly, each bolt 28 and respective nut 30 form parts of a tightening structure that is coupled to the end sections 32 and 34 to selectively reduce the adjustable inner diameter D3 of the tubular clamping portion 22.
The curved section 36 includes a first projection 37a, a second projection 37b and a curved inner surface 37c extending between the projections 37a and 37b. The projections 37a and 37b project radially inwardly from the curved inner surface 37c. The projections 37a and 37b extend in an axial direction substantially parallel to the center axis X. The curved inner surface 37c is configured to retain one of the adapter members 26 thereon, while the projections 37a and 37b are arranged and configured to contact the ends of the adapter member 26 to prevent circumferential movement of the adapter member 26 about the center axis X. The first projection 37a is arranged at the first end section 32, while the second projection 37b is arranged at the second (free) end section 34.

The curved inner surface 27c is preferably a smooth surface. However, it will be apparent to those skilled in the art from this disclosure that the inner surface 27c could be modified if needed and/or desired. For example, the inner surface 27c could be a segmented inner surface is discussed below with reference to the adapter members 26′. In any case, the inner surface of the adapters is preferably configured and arranged to cooperate with the appropriate handlebar such that the mounting member 12 can be clamped thereto.
In this embodiment, the curved inner surface 27c is configured to continuously contact the outer surface of the handlebar 14 when the respective fastener 28 is tightened. Specifically, the curved outer surface 27d is configured to be removably arranged on (i.e., contact) the curved inner surface 37c of the clamping portion 22 to effectively reduce the adjustable inner diameter D3 of the tubular clamping portion 22 (i.e., to be optimal to be clamped onto the handlebar 14). Preferably, the curved outer surface 27d has a U-shaped configuration as viewed circumferentially to form a circumferential channel or recess that partially receives the curved section 36 to prevent axial movement of the adapter member 26 relative to the tubular clamping portion 22.
The free ends 27a and 27b of the adapter member 26 preferably contact the protrusions 37a and 37b to prevent circumferential movement of the adapter member 26 relative to the tubular clamping portion 22 when the adapter member 26 is mounted thereon. In other words, the adapter member 26 preferably has a circumferential length corresponding to the circumferential length of the curved inner surface 37c of the tubular clamping portion 22. Accordingly, when the adapter member 26 is mounted on the curved inner surface 37c of the tubular clamping portion 22, the split 27e of the adapter member 26 remains aligned with the attachment slot 38.
In other words, the inner surface 37c of the tubular clamping portion 22 and the adapter member 26 are arranged and configured to align the split 27e of the adapter member 26 with the attachment slot 38 and to prevent circumferential movement of the adapter member 26 relative to the inner surface 37c of the tubular clamping portion 22. If the split 27e of the adapter member 26 is misaligned with the attachment slot 38 (i.e., such as can happen in the prior art), the fixing force might not be sufficient as desired for some situations. In other words, if the split 27e of the adapter member 26 is misaligned with the attachment slot 38, the mounting member 12 might not be attached as securely to the handlebar 14 or 14′ as desired.
Preferably, the adapter member 26 and the curved inner surface 37c extend around at least a majority of the handlebar 14 relative to the center axis X. More specifically, the adapter member 26 and the inner surface 37c of the tubular clamping portion 22 preferably extend at least about 270 degrees around the center axis X in a continuous, non-segmented manner. However, it will be apparent to those skilled in the art from this disclosure that various modifications are possible so long as the handlebar 14 can be securely clamped.
The adapter member 26 preferably has a minimum radial thickness T at least slightly larger than a maximum radial height H of the projections 37a and 37b such that the projections 27a and 27b do not normally contact the outer surface of the handlebar 14, as best seen in
As mentioned above, the second tubular clamping portion 24 is identical to the first tubular clamping portion 22, except the second tubular clamping portion 24 is a mirror image of the first tubular clamping portion 22. Accordingly, the second tubular clamping portion 24 is basically a substantially C-shaped member that includes a first end section 42, a second (free) end section 44 and a curved section 46 extending between the first and second end sections 42 and 44 to form a split ring configuration with an attachment slot 48. A connecting section 50 extends between the component support portion 20 and the tubular clamping portion 24 (i.e., from both the first end section 42 and the curved section 46 to the component support portion 20).
As mentioned above, since the parts of the second tubular clamping portion 24 are identical to the parts of the first tubular clamping portion 22, except that they are mirror images of each other, the second tubular clamping portion 24 will not be discussed in further detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the second tubular clamping portion 24 functions in a manner substantially identical to the first tubular clamping portion 22 (i.e., with one of the adapter members 26, one of the fasteners 28 and one of the nuts 30).

The modified adapter members 26′ are identical to the adapter members 26, except that the adapter members 26′ have an increased minimum effective thickness T′ that is larger than the thickness T of the adapter members 26, and the adapter members 26′ include a segmented inner surface 27c′. Accordingly, the adapter members 26′ basically include a pair of free ends 27a′ and 27b′ with inner and outer curved surfaces 27c′ and 27d′ extending between the free ends 27a′ and 27b′ to form a split ring configuration with a split 27e′ arranged between the free ends 27a′ and 27b′. The curved inner surface 27c′ is preferably a segmented, curved surface with a plurality of axially extending grooves 27f formed therein. The grooves 27f allow the adapter members 26′ to curve and/or bend despite the increased thickness T′.
The adapter members 26′ are also functionally identical to the adapter members 26. Thus, the adapter members 26′ will not be discussed in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the adapter members 26′ are identical to the adapter members 26, except as explained and illustrated herein. Moreover, it will be apparent to those skilled in the art from this disclosure that the descriptions of the operation of the adapter members 26 also apply to the adapter members 26′.
In this embodiment, the display device 13, the mounting member 12, the fasteners 28, the nuts 30, and the adapter members 26 and/or 26′ preferably form parts of a mountable bicycle structure in accordance with the present invention. However, it will be apparent to those skilled in the art from this disclosure that various modifications can be made to the mountable bicycle structure without departing from the scope of the present invention. For example, modified components can be coupled to modified mounting members in accordance with the present invention, as discussed below with reference to other embodiments of the present invention.
Of course, it will also be apparent to those skilled in the art from this disclosure that other bicycle components not disclosed herein could be provided with a mating structure to be coupled to the component support portion 20 as needed and/or desired, without departing from the scope of the present invention.
