Description

[Detailed Description of the Invention] The present invention relates to a folding saddle to be mounted on a folding bicycle.

Conventionally, saddles used for folding bicycles have been the same as those for ordinary bicycles, or have been made smaller or slimmer. Therefore, since the saddle itself cannot be folded, this has been a cause of poor folding efficiency in folding bicycles, where one of the characteristics is compactness. On the other hand, for this reason, when the saddle itself is made smaller or slimmer, it becomes unstable when riding, and the riding comfort becomes worse. To provide a folding bicycle saddle that has a simple structure, can be folded when not in use, can be easily expanded when in use, and has a satisfactory riding comfort.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. Reference numeral 1 indicates a saddle post, and the lower part is a bicycle frame (not shown).
can be attached to. The upper part of the saddle post 1 is branched into front and rear parts with respect to the direction in which the bicycle travels, and horizontal support shafts 2 and 3 are formed facing each other at the upper end of each branch part. Of these support shafts, a cylinder 4 is rotatably fitted onto the front support shaft 2, and two locking plates 5 and 6 are mounted on the cylinder 4 at a predetermined interval. It is integrally formed. In this case, since the cylinder body 4 is rotatably attached to the front support shaft 2, the locking plates 5, 6
is also rotatable around the support shaft 2. On the other hand, a locking plate 8 integrally formed with the short cylinder 7 is also rotatably attached to the rear support shaft 3, but this locking plate 8 is attached to the front support shaft 3. It is attached to the rear support shaft 3 so as to be located between the two locking plates 5 and 6 attached to the.

Each of these locking plates 5, 6 and 8 has a length that exceeds the distance to the opposing support shaft 2 or 3, and when rotated around each support shaft 2 or 3, each lower surface The rotation is stopped by contacting the opposing support shaft 2 or 3. Therefore, when the locking plates 5, 6, and 8 are rotated and expanded, a triangle connecting the tips of the locking plates 5, 6, and 8 is formed. In this case, it is preferable that the ends of each of the locking plates 5, 6, and 8 are located above the support shafts 2 and 3, as shown in FIG. 1, and in this state, the saddle-shaped leather, A saddle cloth 9 made of cloth or the like can be attached to each tip and stretched, thereby forming a saddle on the upper part of the saddle post 1 as shown in FIG. 4 and making it usable. .

On the other hand, when folding from this state, the saddle cloth 9 is removed and each locking plate 5, 6, and 8 is rotated in the opposite direction. As shown in FIG. 3, the cover 8 can be placed in a substantially vertically hanging state, and can be easily folded. This folding improves the folding ratio of the folding vehicle, making it possible to improve its portability.

In addition, regarding the rotation of the locking plates 5, 6 and 8,
It is also possible to cross each cylinder 3 and 4 with a belt or the like in a figure 8 shape, and as this cross-crossing causes cylinders 3 and 4 to rotate together, each locking plate can be moved individually. This saves you the trouble of rotating it. Further, if a cushion material such as a rubber plate or a spring is attached to the lower surfaces of the locking plates 5, 6 and 8, vibrations can be absorbed and the riding comfort can be improved.

In this way, the present invention has a locking plate rotatably attached to each of the two support shafts attached to the top of the saddle post, making it foldable, so the saddle can be folded when not in use and expanded when in use. can be formed. Therefore, the folding efficiency of the folding bicycle is improved, and the portability of the folding automobile can be further improved.
