JP4903248B2 - Bicycle saddle positioning device and positioning method thereof - Google Patents

Description

  The present invention relates to a positioning device and a positioning method, and more particularly to a positioning device for a bicycle saddle and a positioning method thereof.

  In recent years, awareness of environmental protection has increased, and with the trend of leisure activities, bicycles have become increasingly popular, and user demands for bicycles have also increased.

  Conventionally available bicycle saddles, whether ordinary bicycles or folding bicycles, can be shortened by lowering the seat post to reduce the storage space of the bicycle. However, when the bicycle stored with the seatpost lowered is used again, it was necessary to adjust the saddle to an appropriate height again. Furthermore, it takes time for the user to perform this adjustment work, and the work of reassembling the stored bicycle is troublesome.

It is a disassembled perspective view which shows the positioning device of the bicycle saddle by one Embodiment of this invention. It is the elements on larger scale of FIG. 1 which shows a state when attaching a fastener to a seat post. It is the elements on larger scale of FIG. 1 which shows a state when the bicycle saddle is positioned. FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. It is sectional drawing which shows the positioning device of the bicycle saddle by other embodiment of this invention. 5 is a flowchart illustrating a method for positioning a bicycle saddle according to another embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

  Please refer to FIG. FIG. 1 is an exploded perspective view showing a positioning device for a bicycle saddle according to an embodiment of the present invention.

  As shown in FIG. 1, the bicycle saddle positioning device of the present embodiment includes a groove portion 100, a locking member 110, a fastener 120, and a positioning portion 130.

  The groove portion 100 has a dovetail shape and is provided on the side so as to extend in the axial direction of the bicycle seat post 101. The seat post 101 is movably fitted into the standing pipe 102 of the bicycle.

  The locking member 110 has a dovetail shape so as to slide only in the axial direction in the groove portion 100. The locking member 110 includes two screw holes 111 and two screw members 112 screwed into the screw holes 111. When the locking member 110 is slid to a predetermined position and the screw member 112 is tightened into the screw hole 111 of the locking member 110, the locking member 110 is positioned at a predetermined position in the groove portion 100. Therefore, when the user uses the bicycle again, the position of the saddle can be determined quickly and easily to the height when the user used the bicycle last time.

  When positioning the seat post 101 at a predetermined position, a fastener 120 externally fitted to the standing pipe 102 for tightly fixing the seat post 101 into the standing pipe 102 is used. The fastener 120 is provided with a positioning portion 130 that protrudes into the groove portion 100. When the locking member 110 is locked at a predetermined position in the groove portion 100, the positioning member 130 prevents the locking member 110 from moving. Therefore, when the user uses the bicycle again, the height when the user uses the bicycle again is used. Saddle position can be adjusted quickly and easily.

  Please refer to FIG. 2 and FIG. FIG. 2 is a partially enlarged view of FIG. 1 showing a state when the fastener is attached to the seat post. FIG. 3 is a partially enlarged view of FIG. 1 showing a state when the bicycle saddle is positioned.

  As shown in FIG. 2, after the locking member 110 is locked to a predetermined position in the groove portion 100 by the screwing member 112, the fastener 120 is loosened, and the seat post 101 is inserted into the standing pipe 102. As a result, the storage space of the bicycle can be reduced, and the seat post 101 when the bicycle is used can be positioned.

  As shown in FIG. 3, when the seat post 101 is pulled up and the locking member 110 locked at a predetermined position comes into contact with the lower portion of the positioning portion 130, the movement is blocked. At this time, the seat post 101 has the same height as the previous use. As described above, when riding a bicycle, the seat post 101 can be positioned and fastened and fixed to a height desired by the user only by using the fastener 120.

Please refer to FIG. 4 is a cross-sectional view taken along line 4-4 of FIG.
When the screw member 112 is screwed into the screw hole 111, the end portion of the screw member 112 protruding from the screw hole 111 is brought into contact with the groove portion 100. As a result, since the locking member 110 is closely locked at a predetermined position of the groove portion 100, when the user uses the bicycle, the position of the seat post 101 can be quickly and easily determined to the height that is always used. Can do.

  Please refer to FIG. FIG. 5 is a cross-sectional view showing a positioning device for a bicycle saddle according to another embodiment of the present invention.

  The locking member 510 is an elastic member that includes a hole 511 and a pressing piece 512. A hole 511 is formed in the locking member 510 so as to be perpendicular to the extending direction of the groove 100. The locking member 510 is pressed and deformed by the pressing piece 512 in contact with the hole 511 and is locked in the groove 100.

  The diameter of the hole 511 is smaller than the pushing piece 512, and gradually decreases from the outside toward the inside. As a result, the locking member 510 is deformed by the pressing piece 512 in contact with the hole 511 and is tightly locked into the groove 100.

  Please refer to FIG. FIG. 6 is a flowchart illustrating a method for positioning a bicycle saddle according to another embodiment of the present invention.

  As shown in FIG. 6, the bicycle saddle positioning method according to the present embodiment includes the following steps 600 to 630.

  Step 600: The locking member arranged on the side of the bicycle seat post is slid in the axial direction of the seat post.

  Step 610: The locking member is positioned at a predetermined position on the side of the seat post according to the desired height of the seat post.

  Step 620: Before lowering the seat post, the height of the seat post that is always used is positioned by the locking member, and then the seat post is put into the vertical pipe of the bicycle.

  Step 630: When the user pulls out the seat post again, the movement of the locking member is prevented by the positioning part of the standing pipe, and the position of the seat post can be determined to a predetermined height. In this way, the position of the seat post can be determined to a predetermined position simply and quickly by adjusting to the height used last time.

  As can be seen from the above, when the user finishes using the bicycle and stores it, the locking member is locked to the height of the seat post that is always used, and then the seat post is inserted into the standing pipe. Fit. When the bicycle is used next time, if the seat post is pulled out to the position where the previous locking member is locked, the locking member is prevented from moving by the positioning portion of the fastener, so the seat post is pulled out to the position used last time. And it can no longer be pulled out. In this manner, the user can quickly and easily determine the position of the seat post to the height when used last time.

  While preferred embodiments of the present invention have been disclosed above, so that those skilled in the art can practice them, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims according to the present invention should be construed broadly including such changes and modifications.

  100: groove portion, 101: seat post, 102: standing pipe, 110: locking member, 111: screw hole, 112: screwing member, 120: fastener, 130: positioning portion, 510: locking member, 511: hole Part, 512: pushing piece.
