DETAILED DESCRIPTION OF THE INVENTION
The detailed description and technical contents of the present invention will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention.
As shown in FIG. 3 and FIG. 4, a control module 1 of the first preferred embodiment of the present invention is mounted on a handlebar 2 of a bicycle. The control module 1 is connected to a brake module (not shown) through a wire 3. The control module 1 includes a base 10, a grip 15, a control bar 20, and a bolt 25.
The base 10 has a hole 11, a gap 12 communicated with the hole 11, and two bores 13 at opposite sides of the gap 12. The hole 11 has a first section 111 and a second section 112. The second section 112 is bigger than the first section 111. The base 10 is fitted to the handlebar 2 and a sidewall of the first section 111 touches the handlebar 2.
The grip 15 is fitted to the handlebar 2. The grip 15 has an opening 17 at an end 16 proximal to the base 10, and two protrusions 18 at opposite sides of the opening 17. The protrusions 18 are projected from the end 16 of the grip 17 and received in the second section 112 of the hole 11 of the base 10. The grip 15 further has a flange 19 surrounding the opening 17 to be against the base 10.
The control bar 20 is pivoted on the base 10 to be operated by rider to control the brake module through the wire 3.
The bolt 25 is inserted into the bores 13 of the base 10 to engage a nut 26. As shown in FIG. 5, both the base 10 and the grip 15 are fitted to the handlebar 2, and the protrusions 18 are received in the second section 112 of the hole 11 of the base 10 and the flange 19 touches the base 10. The base 10 and the grip 15 are fixed to the handlebar 2 at the same time by tightening the bolt 25.
FIG. 6 and FIG. 7 show a control module 4 of the second preferred embodiment of the present invention, which is mounted on the handlebar 2 to control the brake module through the wire 3. The control module 4 has a base 30, a grip 35, a control bar 36, and a bolt 37 wherein the grip 35, the control bar 36, and the bolt 37 are the same as above.
The base 30 has a body 31 and a pressing member 32. The pressing member 32 has an end pivoted on the body 31 so that a hole 33 is formed between the body 31 and the pressing member 32, and a gap 34 is formed between a free end of the pressing member 32 and the body 31. The hole 33, the same as above, has a first second 331 and a second section 332. The second section 332 is bigger than the first second 331. The handlebar 2 engages the first section 331 of the base 30. The bolt 37 is inserted into bores at opposite sides of the gap 34 to engage a nut. The same as above the grip 35 and the base 30 are firmly fixed to the handlebar 2 by tightening the bolt 37.
FIG. 8 and FIG. 9 show a control module 5 of the third preferred embodiment of the present invention, which is mounted on the handlebar 2 to control the brake module through the wire 3. The control module 5 has a base 40, a grip 45, a control bar 46, and two bolts 47 wherein the grip 45, the control bar 46, and the bolts 47 are the same as above. The base 40 has a body 41 and a pressing member 42. The pressing member 42 respectively has a bore 421 at opposite ends, and the body 41 has two threaded bores (not shown). The body 41 and the pressing member 42 are fixed together while the bolts 47 are inserted into the bore 421 of the pressing member 42 and screwed into the threaded bores of the body 41. The same as above, the body 41 and the pressing member 42 form a hole 43. The hole 43 has a first section 431 and a second section 432, and the second section 432 is bigger than the first section 431. The base 40 is fitted to the handlebar 2, and a sidewall of the first section 431 touches the handlebar 2. The grip 45 has a portion receive in the second section 432 of the base 40. The same as above the grip 45 and the base 40 are firmly fixed to the handlebar 2 by tightening the bolts 47.
The control module may be used to control a hydraulic brake also so that the control bar is connected to a hose, in which fluid flows to activate the brake.
FIG. 10 and FIG. 11 show a control module 6 of the fourth preferred embodiment of the present invention, which is mounted on the handlebar 2 to control a derailleur module (not shown) through the wire 3. The control module 6 has a base 50, a grip 55, two control bars 60, and a bolt 65.
The base 50 has a hole 51 and a gap 52. The gap 52 is communicated with the hole 51. The hole 51 has a first section 511 and a second section 512, which is bigger than the first section 511. The base 50 is fitted to the handlebar 2, and a sidewall of the first section 511 touches the handlebar 2.
The grip 55 is fitted to the handlebar 2. The grip 55 has an opening 57 at an end 56 proximal to the base 50 and two protrusions 58 at opposite sides of the opening 57. The protrusions 58 are received in the second section 512 of the hole 51 of the base 50. The grip 55 further has a flange 59 surrounding the opening 57 to be against the base 50.
The control bars 60 respectively are pivoted on the base 50 to control the derailleur module (not shown) through the wire 3.
The bolt 65 is inserted into bores on the base 50. The same as above, the base 50 and the grip 55 are fixed to the handlebar 2 at the same time by tightening the bolt 65.
FIG. 12 and FIG. 13 show a control module 8 of the fifth preferred embodiment of the present invention, which is similar to the above embodiments, except that a base 75 includes a body 751 and two pressing members 752. The body 751 has a hole 753, and the hole 753 has a first section 753a and a second section 753b. The body 751 further has a through hole 754. The through hole 754 is above the hole 753 and is perpendicular to the hole 753. The through hole 754 is communicated with the hole 753 at the second section 753b. The pressing members 752 are received in the through hole 754, and a bolt 76 is inserted into one pressing member 752 and screwed into another pressing member 752.
As shown in FIG. 14, except that the first section 753a is pressed on the handlebar (not shown) and the second section 753b is pressed on the grip 80, the pressing members 752 move inward and enter the hole 753 to press the grip 80 while the bolt 76 is tightened so that the grip 80 is firmly fixed to the body 751.
The conventional grip may be incorporated in the present invention. As shown in FIG. 15 and FIG. 16, the control module has the base 10, the control bar 20, the bolt 25, and a conventional grip 70 (without the protrusion), wherein the base 10, the control bar 20, and the bolt 25 are the same as the first preferred embodiment. The base 10 is fitted to the handlebar 2, and a sidewall of the first section 111 touches the handlebar 2. The conventional grip 70 has a portion received in the second section 112 of the hole 11 of the base 10. The same as above, the base 10 and the grip 70 are fixed to the handlebar 2 by tightening the bolt 25. Except for the first preferred embodiment, the conventional grip 70 may be incorporated in the base of the second, the third, the fourth, or the fifth preferred embodiment also.
The present invention provides an end of the grip to engage the base so that the grip still has a large area to be held by a rider. It will not interfere with operation of the bicycle when the rider holds the grip to provide the rider an easy and safe way to ride the bicycle.
The description above is a few preferred embodiments of the present invention, and the equivalence of the present invention is still in the scope of claim construction of the present invention.
