Description

  The present invention relates to a saddle capable of efficiently running a bicycle, a saddle mounting member, and a bicycle.

  In general, a bicycle travels by driving a rear wheel by passing a chain between a free wheel of a rear wheel and a chain wheel to which a crank is attached, and rotating the crank with a pedal provided at the tip of the crank. At that time, if the pedaling force can be transmitted to the pedal more efficiently, the bicycle can be driven more easily. However, when pedaling, one foot is lowered, the other leg is raised, and the hips move up and down accordingly, whereas in conventional bicycles, the saddle is against the saddle post. The hips are difficult to move and the movement is restricted. Therefore, there is a problem that it is difficult to sufficiently transmit the force to the pedal.

JP 2005-319930 A

  The present invention has been made based on such a problem, and an object of the present invention is to provide a saddle, a saddle mounting member, and a bicycle that can more efficiently transmit pedaling force to a pedal.

  Patent Document 1 discloses a saddle device that can be operated easily while suppressing a load applied to a passenger's waist by allowing a saddle support pipe that supports the saddle to be slightly swung in a radial direction and a circumferential direction. Are listed. However, the specific configuration is different from the present invention.

  The saddle of the present invention is arranged with respect to a saddle column of a bicycle and has a seat, and the seat is tilted so that the left or right side of the seat can be lowered compared to the other. Rotating means disposed so as to be rotatable with respect to the saddle column is provided.

  The saddle mounting member of the present invention attaches a saddle having a seat to a saddle post, and the saddle is attached to the saddle so that the seat can be inclined and the left or right side of the seat can be lowered compared to the other. Rotating means disposed so as to be rotatable with respect to the support column is provided.

  The bicycle of the present invention includes the saddle of the present invention or the saddle mounting member of the present invention.

  According to the present invention, the seat can be tilted so that the left or right side of the seat can be lowered compared to the other. For example, when pedaling with the right foot, the right side of the seat is lower than the left side. The seat is inclined so that the right hip can be easily moved down. Also, when pedaling with the left foot, the seat tilts so that the left side of the seat is lower than the right side, and the left hip can be easily moved down. Therefore, it is possible to depress the pedal more powerfully, and it is possible to transmit the power to the pedal more efficiently. In addition, since the seat tilts in accordance with the movement of the buttocks, the center of gravity can be easily moved to the left and right while sitting on the seat, and the weight can be applied to the stepped foot side. Therefore, the same effect as standing can be obtained. Furthermore, since the seat moves in accordance with the movement of the buttocks, the friction between the buttocks and the seat can be reduced and the vehicle can travel comfortably.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
The first embodiment of the present invention relates to a saddle and a bicycle having the same. FIG. 1 shows the configuration of a saddle according to the present embodiment, and shows a cross-sectional structure cut in the front-rear direction at the center in the width direction. FIG. 2 shows a cross-sectional structure taken along the line II shown in FIG. The saddle 10 is disposed with respect to a saddle strut (not shown) of the bicycle. For example, a seat 11 and the seat 11 are disposed with respect to a saddle strut (not shown) of the bicycle. The saddle strut mounting portion 12 is provided. The seat 11 has a configuration in which, for example, an elastic body 11B is disposed on a base 11A, and the top is covered with an epithelium 11C. The saddle strut mounting portion 12 is constituted by, for example, a pair of saddle rails 12A. The saddle rail 12A has, for example, a linear portion 12B supported by a clamp (not shown) of a saddle column, and seat support portions 12C for supporting the seat 11 are provided at both ends thereof.

  The saddle 10 can also rotate the seat 11 with respect to the saddle strut mounting portion 12 (that is, the saddle strut) so that the seat 11 can be inclined so that the left or right side of the seat 11 can be lower than the other. Rotating means 13 is provided. The left side or the right side of the seat 11 means the left side or the right side in the width direction when the saddle nose 11D, that is, the narrow portion at the tip of the seat 11 is the front side. The rotation means 13 includes, for example, a rotation support portion 13A that is fixedly disposed on the saddle strut mounting portion 12, and one end portion that is fixedly disposed on the front center portion of the base 11A of the seat 11 and the other end. And a rotating shaft bar 13B that is fixedly disposed at the rear center of the base 11A. For example, at least a part of the rotating shaft bar 13B is disposed so as to be rotatable with respect to the rotation support portion 13A between the both end portions, whereby the seat 11 is moved to a pair of saddle rails 12A, that is, saddle struts. It arrange | positions so that rotation with respect to the attaching part 12 is possible.

  The rotation support portion 13A and the rotation shaft rod 13B are not rotatable, but the rotation support portion 13A and the rotation shaft rod 13B are fixed, and the rotation shaft rod 13B is rotated with respect to the base 11A. Further, the rotation support portion 13A may be provided with a projection corresponding to the rotary shaft 13B, and the rotation support portion 13A is rotated with respect to the base 11A by this projection. You may make it arrange | position so that it is possible.

  The distance between the rotation center line 13C of the rotary shaft 13B and the surface of the seat 11 is such that the distance L1 at the front position where the rotary shaft 13B is disposed with respect to the base 11A is the rotary shaft 13B. Is preferably longer than the distance L2 at the rear position where it is disposed with respect to the base 11A. This is for preventing the slip of the crotch by largely rotating the side of the saddle nose 11D. For example, the intersection angle θ1 between the straight line connecting the surface positions of the seat 11 corresponding to the front and rear positions where the rotary shaft 13B is disposed with respect to the base 11A and the rotation center line 13C is 0 °. Is preferably 30 ° or less and more preferably 10 ° or more and 20 ° or less. In the saddle center 10A in the front-rear direction of the saddle 10, the height H from the rotation center line 13C to the surface of the seat 11 is preferably -20 mm or more and 60 mm or less, and more preferably 0 mm or more and 40 mm or less. This is because if the surface of the seat 11 is too high from the rotation center line 13C, it is difficult to rotate, and if it is too low, a stepping loss occurs and a great effect cannot be obtained. Note that the saddle center 10A refers to a vertical plane passing through the center of the straight portion 12B of the saddle rail 12A in the front-rear direction of the saddle 10 in a state where the front, rear, left and right of the center portion of the seat 11 are horizontal. In addition, when the height H from the rotation center line 13C to the surface of the seat 11 is negative, the surface of the seat 11 is located below the rotation center line 13C. This is a case where the surface is located above the rotation center line 13C.

  The saddle 10 further includes a reference position holding member 14 for holding the seat 11 at the reference position when no force is applied to the seat 11. The reference position is a position where the left and right sides of the seat 11 are horizontal when the saddle 10 is disposed on a saddle column (not shown). For example, when the pair of saddle rails 12A are held at the same height, The left and right sides of the seat 11 are horizontal positions. For example, the reference position holding member 14 returns the seat 11 to the reference position when the left side of the seat 11 is tilted so as to be lower than the right side or when the right side of the seat 11 is tilted so as to be lower than the left side. It has a biasing member 14A such as a spring that biases the spring. The urging member 14A is configured, for example, in a circular arc shape with a part opened, and is disposed with respect to the base 11A. A projecting portion 14C provided so as to project from the rotation support portion 13A in the length direction of the rotating shaft 13B is inserted into the opening portion 14B of the urging member 14A, and the projecting portion 14C is held at the reference position. Is energized. Further, it is preferable that the maximum rotation angle of the base 11A with respect to the protrusion 14C (that is, the maximum rotation angle of the seat 11 with respect to the saddle strut mounting portion 12) θ2 is adjusted from ± 10 ° to ± 20 ° around the reference position. More preferably, the angle is adjusted from ± 13 ° to ± 18 °. For example, it is preferable to provide a stop (not shown) that stops the seat 11 from rotating more than the maximum rotation angle.

  FIG. 3 shows the movement viewed from the rear side of the saddle 10. In this saddle 10, when the right foot is lowered when pedaling with the right foot, the right hip is lowered and the right side of the seat 11 is pushed downward. For example, as shown in FIG. The seat 11 is inclined so that the right side is lower than the left side and the left side is higher than the right side. When the right foot is raised, the force applied to the right side of the seat 11 becomes weaker and the seat 11 returns to the reference position by the reference position holding member 15. Further, when the left foot is lowered when pedaling with the left foot, the left hip is lowered and the left side of the seat 11 is pushed down. For example, as shown in FIG. The seat 11 is inclined so that the right side is higher than the left side. When the left foot is raised, the force applied to the left side of the seat 11 is weakened, and the seat 11 is returned to the reference position by the reference position holding member 15.

  As described above, according to the saddle 10 of the present embodiment, the seat 11 is inclined so that the left or right side of the seat 11 can be lowered as compared with the other. Accordingly, the seat 11 is inclined and the butt can be easily moved downward. Therefore, it is possible to depress the pedal more powerfully, and it is possible to transmit the power to the pedal more efficiently. Moreover, since the seat 11 is inclined according to the movement of the buttocks, the center of gravity can be easily moved to the left and right while sitting on the seat 11, and the weight can be applied to the stepping foot side. Therefore, the same effect as standing can be obtained. Furthermore, since the seat 11 moves in accordance with the movement of the buttocks, the friction between the buttocks and the seat 11 can be reduced and the vehicle can travel comfortably. In addition, since the seat 11 is rotated about the rotation center line 13C, the front and rear, the top and bottom, and the left and right of the seat 11 are fixed, the loss can be eliminated and the stability can be improved. You can step in powerfully.
