Referring to fig. 1 to 7, which show a first embodiment of the present invention, an adjustable five-way mechanism 1 of the present invention includes a five-way pipe 2, an axial portion 4 and a supporting portion 6.
The five-way tube 2 is provided with at least one through hole 3 for connecting a seat tube 900, and the length extending direction of the seat tube 900 is defined as a first direction 10. The shaft-mounting portion 4 is provided with at least one shaft hole 5 and is axially disposed corresponding to the at least one shaft through hole 3, and the at least one shaft hole 5 and the at least one shaft through hole 3 are provided for a day shaft 950 to pass through. The supporting portion 6 is connected to the shaft portion 4 and is adjustably fixed to the bottom bracket 2 at a first position or a second position. Wherein, when the supporting portion 6 is located at the first position or the second position, an axis of the at least one axial through hole 3 and an axis of the at least one axial hole 5 are both located in the first direction 10; the positions of the axis of the axial hole 5 when the supporting portion 6 is located at the first position and the second position are different positions in the first direction 10 (please refer to fig. 3 and 4, the axis 602 of the axial hole 5 is located in the first direction 10 when the supporting portion 6 is located at the first position, and the axis 601 of the axial hole 5 is also located in the first direction 10 when the supporting portion 6 is located at the second position). Thus, the position of the top axle 950 in the first direction 10 can be adjusted to adjust the center of gravity of the pedal during riding the bicycle.
In the present embodiment, the shaft portion 4 is eccentrically connected to the supporting portion 6, and the supporting portion 6 can change the position of the shaft portion 4 relative to the first direction 10 through rotation. The shaft-setting portion 4 is a tube inserted into the at least one shaft-through hole 3, and the tube is provided with the at least one shaft hole 5. The supporting portion 6 is provided with a flange 60 protruding radially, and the flange 60 is located at one end of the pipe and embedded in the bottom bracket 2.

The five-way pipe 2 includes two shaft through holes 3, and the axes of the two shaft through holes 3 are located at different positions in the first direction 10. The two-axis through holes 3 are overlapped and communicated with each other by a minor arc portion, so that the five-way pipe 2 forms a protruding stop portion 30 at the minor arc overlapped portion, which can be blocked against the axial portion 4 to prevent the axial portion 4 from moving directly between the two-axis through holes 3.
The flange 60 is provided with a plurality of through holes 61, the plurality of through holes 61 includes two first through holes 62 and two second through holes 63, the two first through holes 62 are located in a second direction 11, the second direction 11 is perpendicular to the first direction 10, the two second through holes 63 are respectively located on two sides of the first direction 10 and two sides of the second direction 11, and the plurality of fastening members 64 are at least partially inserted through the plurality of through holes 61 to position the flange 60 on the bottom bracket 2. In detail, the two second through holes 63 respectively keep equal distances from the first direction 10, four quadrants are defined by the first and second directions 10 and 11, the two second through holes 63 are respectively located in two quadrants of the diagonal direction, a straight line passing through the origin of the quadrants is defined in any direction, and the shapes of the support part 6 on the left and right sides of the straight line are equal.
The distance from the second through hole 63 to the axis of the shaft hole 5 is different, and the height of the shaft portion 4 is larger when the supporting portion 6 rotates 180 degrees. The maximum vertical height difference of the top axle 950 before and after the adjustment of the adjustable five-way mechanism 1 is preferably not less than 2.5 cm. The supporting portion 6 includes a first ring 65 and a second ring 66 coaxially connected to the axial portion 4, and the second ring 66 is adjacent to the bottom bracket 2 and has a radial dimension larger than that of the first ring 65. The second ring 66 is provided with a protruding ring 67 protruding away from the axial portion 4. In use, the chainring of the bicycle is located on the same side of the second ring 66, and the raised ring 67 of the second ring 66 helps to keep the chainring spaced from the frame of the bicycle.
The first ring 65 is radially necked down at a half of the radial dimension toward the second ring 66 to define a first necked-down portion 650, and the second ring 66 is radially necked down at a two-thirds of the radial dimension toward the first ring 65 to define a second necked-down portion 660, and the inner wall of the bottom bracket 2 has a corresponding necked-down shape (see fig. 5 to 7), so that the first and second rings 65,66 can be more stably positioned (when the first and second rings 65,66 are mounted on the bottom bracket 2, the first and second necked-down portions 650,660 can help to be locked and fixed).
Referring to fig. 8, in the second embodiment, the supporting portion 6a may also have a plurality of axial portions 4a, so that the adjustment can be performed by directly disposing the central axis 950a on one of the axial portions 4a without detaching the supporting portion 6 a.
Referring to fig. 9, in the third embodiment, the plurality of axial portions 4b of the supporting portion 6b may not be connected to each other at all.
In other embodiments, the flange of the supporting portion may be non-embedded in the five-way pipe, such as but not limited to being fixed to the outer wall of the five-way pipe; the five-way pipe can also comprise other numbers of shaft through holes which can be overlapped and communicated with the minor arc part selectively; the shaft part can also be connected with the supporting part without eccentricity; the shaft portion can also be directly the at least one shaft hole; the flange may also be fixed to the five-way pipe in other ways, such as but not limited to using a tenon structure, and the installation position of the through holes is not limited, but the flange may be firmly positioned on the five-way pipe; the radial dimensions of the first and second ring members may also be equal; the first and second ring members may not have the first and second necked-down portions; the position of the first or/and second necking portion is not limited, but can be used for assisting the first or/and second ring body to be stably positioned; the rotation angle of the support portion is not limited, for example, the support portion may be rotated 180 degrees or 90 degrees and then installed on the five-way tube, but only the axis of the shaft hole of the support portion is located in the first direction.
In conclusion, the adjustable five-way mechanism can adjust the height of the center of gravity of the treading to meet the riding requirement, and the whole structure is stable and convenient.
