DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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.

As used herein to describe the present invention, the following directional terms “front”, “rear”, “forward”, “rearward”, “left”, “right”, “transverse”, “upward” and “downward” as well as any other similar directional terms refer to those directions which are determined on the basis of the rider who sits on a saddle of a bicycle (not shown) with facing a bicycle handlebar 100, for example. Accordingly, these terms, as utilized to describe the present invention should be interpreted relative to the bicycle equipped with the present invention as used in the normal riding position on a level surface.

Referring to FIGS. 1-4E, an operating device 10 that is adapted to be mounted on or attached to the bicycle handlebar 100 is illustrated in accordance with an embodiment of the present invention. The operating device 10 generally includes a fixing member 12 and a housing 14 that includes first and second members 16 and 18. In a preferred embodiment, the fixing member 12 includes a fixing portion 20 and an adjustment portion 22 (FIG. 2). The fixing portion 20 is adapted to be attached to the bicycle handlebar 100. In a preferred embodiment, the fixing portion 20 is formed as a C-shape member and is fixed to the bicycle handlebar 100 by using a fastener member, e.g., a bolt (not shown). Such clamp members are well known in the art and, therefore, other types of clamp members or fixing portions can be used. An open clamp type fixing member comprising two hingedly pivotable parts can be used, for example.

As is shown in FIG. 3, the first and second members 16 and 18 define an adjustment space 24 therebetween that receives at least a portion of the adjustment portion 22. In a preferred embodiment, the adjustment portion 22 is adjustable with respect to the housing 14 (within the adjustment space 24) in at least a first adjustment direction D1 and preferably also in a second adjustment direction D2. The adjustment portion 22 is preferably clamped between the first and second members 16 and 18. To secure the adjustment portion 22 in a desired position, the housing 14 includes at least one third member 26 that secures or fixes the first member 16 and the second member 18 to each other. In a preferred embodiment, the third members 26 are threaded fasteners or bolts that extend from the first member 16 to the second member 18 (or vice versa) and are screwed into the second member 18 so as to clamp the adjustment portion 22 therebetween. In another embodiment, the third member can be a protrusion or protrusions provided one of the first and second members to snap-fit it to the other of the first and second members. Preferably, the third members 26 extend without passing through the adjustment portion 22, which allows the adjustment portion 22 to be adjustable in at least the first adjustment direction D1 without having to remove the third members 26 from the housing 14.

As shown in FIG. 2, in a preferred embodiment, the fixing member 12 includes a neck portion 28 extending between the fixing portion 20 and the adjustment portion 22. In a preferred embodiment, the portion of the neck portion 28 that is immediately adjacent the adjustment portion 22 is thicker than the adjustment space 24. This prevents the neck portion 28 from extending into the adjustment space 24.

As shown in FIGS. 1-4E, in a preferred embodiment, adjustability is provided by complementary protrusions 30 and channels or recesses 32. It will be appreciated by those skilled in the art that the protrusions 30 and recesses 32 can be disposed on the adjustment portion 22 and/or the housing 14. Furthermore, the protrusions 30 and recesses 32 can be formed or positioned on either or both sides of the adjustment portion 32 and on the inside surface of either or both of the first and second members 16 and 18. In the figures, the protrusions 30 are formed on the adjustment portion 22 and the recesses 32 are formed on the first member 16 of the housing 14. However, this is not a limitation on the present invention. Further, in the figures, the number of the protrusions 30 is three and the number of the recesses 32 is five. However, this is not a limitation on the present invention. The recess(es) 32 can be provided in at least the same number as the protrusion(s) 30. However, there are preferably more recesses 32 than protrusions 30 to achieve the adjustability described below. Any number of recesses 32 and protrusions 30 are within the scope of the present invention.

As shown in FIG. 2, the recesses 32 are elongated and extend in a parallel direction with respect to each other such that the recesses 32 allow the protrusion 30 to slide therealong. In its simplest form, a single protrusion 30 can be slidably received in a single recess 32, thereby allowing adjustability in a first adjustment direction D1 parallel to the length of the recess 32.

In a preferred embodiment, the first member 16 includes more recesses 32 than the protrusions 30 of the adjustment portion 22. This allows adjustability in a second adjustment direction D2 that is generally perpendicular to the first adjustment direction D1.

Adjustment of the position of the housing 14 with respect to the fixing member 12 when the fixing portion 20 is fixed to a bicycle handlebar 100 will now be described. FIGS. 4A-4E show the housing 14 (and components thereof) positioned at a plurality of different locations with respect to the fixing member 12.

FIGS. 4A-4B demonstrate adjustment in the first adjustment direction D1. In FIG. 4B it can be seen that the entire housing member 14 has moved in the first adjustment direction D1 (specifically, it has moved to a rider's left) compared to FIG. 4A (as the fixing members 12 are lined up vertically in FIGS. 4A and 4B). This is done by loosening the third members 26, and moving the housing 14 to the left, such that the protrusions 30 slide within the recesses 32 to the desired position, and then retightening the third members 26 to clamp the adjustment portion 22 between the first and second members 16 and 18 within the adjustment space 24.

FIGS. 4C-4D demonstrate adjustment in the second adjustment direction D2. In

FIG. 4D it can be seen that the entire housing member 14 has moved in the second adjustment direction D2 (specifically, it has moved forward with respect to a rider) compared to FIG. 4C (as the fixing members 12 are lined up horizontally in FIGS. 4C and 4D). This is done by loosening the third members 26, moving the first member 16 and the second member 18 with respect to each other so that the protrusions 30 can be displaceable to different recesses 32, moving the housing 14 forwardly with respect to the fixing member 12 so as to align the protrusions 30 with different recesses 32, placing the first and second members 16 and 18 back together, and then retightening the third members 26 to clamp the adjustment portion 22 between the first and second members 16 and 18 within the adjustment space 24.

FIG. 4E shows within a single figure a combination of adjustment in the first adjustment direction D1 and the second adjustment direction D2, which results in diagonal adjustability. Accordingly, it will be appreciated by those of skill in the art that providing adjustability in the two different directions provides a wide range of adjustability from a first position (represented by the adjustment portion 22 that includes the fixing portion 20) to any second position (represented by the adjustment portion labeled 22a).

As is shown in FIGS. 4A-4E, in a preferred embodiment, the first adjustment direction D1 is parallel to an axis Al defined by the bicycle handlebar 100 when the operating device 10 is mounted on a bicycle handlebar 100 and the second adjustment direction D2 is perpendicular to the first adjustment direction D1. However, this is not a limitation on the present invention.

In a preferred embodiment the operating device 10 includes first and second operating members 34a and 34b that are operatively coupled to the housing 14. Preferably, the first and second operating members 34a and 34b are part of an operating unit 36 that is coupled to the first member 16. The operating members 34a and 34b can be used, for example, for shifting gears on a bicycle. In a preferred embodiment, the first and second operating members 34a and 34b are trigger levers that are movable between a rest position and an operating position.

FIG. 5 shows an operating device 10a which is another preferred embodiment of the present invention. In this embodiment, the elongated recesses and protrusions are omitted and are replaced by recesses 38 and protrusions 40. It will be understood that recesses 38 and protrusions 40 do not provide sliding adjustability. Instead, adjustment is provided by removing or loosening the second member 18 and moving the protrusions 40 to a different set of recesses 38. In this embodiment, adjustment can be made in both the first adjustment direction D1 and the second adjustment direction D2 by selectively moving the protrusions 40 into different recesses 38. In its simplest form, a single protrusion 40 and a plurality of recesses 38 are provided and the protrusion 40 can be moved from one recess 38 to another recess 38 to provide adjustability. The recesses 38 and protrusions 40 can be any shape provided a male and female relationship exists between the two.
