Abstract

PROBLEM TO BE SOLVED: To provide a saddle rotatably supporting mechanism capable of rotatably supporting the saddle between a tilted position and a riding position relative to the body frame of a bicycle for securing a stable riding condition and a good operability. SOLUTION: A saddle 1 is rotatably supported between the tilted position as shown in the figure (c) and the riding position as shown in the figure (a), and the saddle is provided with a hook member 5 for keeping the saddle in the riding position, and by engaging the hook member 5 with the saddle 1, the rotatable saddle can be stably maintained in the riding position. Further, the hook member 5 is energized in the maintaining position by means of an energizing means.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle rotation support mechanism for a bicycle.

[0002]

2. Description of the Related Art A saddle as a seat device of a bicycle is mounted in a riding position on an upper end of a saddle pipe that can be adjusted in height with respect to a body frame, and the saddle height is appropriately adjusted according to a user's physique. It is used after changing to a different position.

[0003]

When the saddle of a bicycle is configured to be rotatable between a tilted position and a riding position,
At present, it is not possible to secure the saddle in a stable riding state with simple operations. SUMMARY OF THE INVENTION It is an object of the present invention to provide a saddle rotation support mechanism that can secure a saddle in a stable riding state and has good operability.

[0004]

SUMMARY OF THE INVENTION A saddle rotation support mechanism of the present invention holds a saddle rotatably supported between a tilted position and a riding position with respect to a bicycle body frame in a riding position. A hook member is provided. According to the present invention, the rotatable saddle can be stably held at the riding position by engaging the hook member with the saddle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The saddle rotation support mechanism of the present invention
A saddle rotation support mechanism rotatably supporting a saddle of a bicycle between a tilted position and a riding position with respect to a body frame of the bicycle, and a rotatable hook member for holding the saddle in the riding position. It is characterized by having.

According to this structure, the rotatable saddle can be stably held at the riding position by the hook member. FIG. 1 is a perspective view showing a main part of a bicycle provided with a saddle rotation support mechanism of the present invention, FIG. 2 is a front view showing a saddle rotation support mechanism and a lock mechanism, and FIG. 3 is a view for explaining the operation of the lock mechanism. , FIG.
Is a view showing the internal structure of the lock mechanism, FIG. 5A is a perspective view of the bicycle in a normal riding state (a state in which the saddle is in the riding position), and FIG. FIG. 2 is a perspective view of the bicycle in a state in which it is impossible to ride (a state in which the saddle is in a tilted position).

As shown in FIGS. 1 and 2, the saddle 1 is
A locking member 4 at a lower portion of the saddle 1 is rotatably supported by a support portion 3 at an upper end of the saddle support pipe 2, and the entire saddle 1 is supported by the support pipe 2 so as to be tiltable. Saddle 1
When the vehicle is in the state shown in FIG. 2, that is, in the state shown in FIG. 5A, the spring-equipped hook 5 attached to the support member 3 of the saddle support pipe 2 can hold the saddle 1 in the riding position. In the holding state, the rear portion of the locking member 4 of the saddle 1 is locked, and the saddle 1 does not tilt.

When the saddle 1 is changed from the state shown in FIG. 2 to the state shown in FIG. 1, that is, the state shown in FIG. Release the locking of the rear part of the member 4 and tilt the saddle 1 forward. Lock mechanism 6 when saddle 1 is tilted forward
3 will be described with reference to FIGS. FIG. 3A shows the same state as FIG. 2, and FIG.
2 shows a state in which the locking of the rear part of the locking member 4 of the saddle 1 is released (a state in which the hook 5 is at the open position), and FIG. 3C shows a state in which the saddle 1 is tilted forward.

As shown in FIG. 4, the lock mechanism 6 has a moving piece 9 urged by a compression spring 8 inside a casing 7 and is formed on the engaging member 4 of the saddle 1 through an opening 7a of the casing 7. When the locking piece 4a is inserted, the projection 9a of the moving piece 9 protrudes into the locking hole 4b of the locking piece 4a,
The locking piece 4 a is configured to be locked by the moving piece 9.

By the operation of the lock mechanism 6, when the saddle 1 is tilted forward as shown in FIG. 3C, the saddle 1 is locked in this state. In this state, as shown in FIG. 5 (b), it can be seen at a glance that the bicycle cannot be ridden, and the anti-theft effect is great. With the saddle 1 locked, the locking mechanism 6
When the key 10 is pushed in from the key hole 7b of the casing 7, the moving piece 9 is pushed, the projection 9a comes out of the locking hole 4b of the locking piece 4a, and the lock is released. In order to release the lock and allow the rider to ride on the bicycle, the lock may be released and the saddle 1 may be returned to the state shown in FIG.

Although the above-described embodiment is an example in which the saddle is tilted forward, the saddle is tilted by providing a similar lock mechanism when the saddle is tilted backward or left and right. Can be locked in state.

[0012]

As described above, the saddle rotation support mechanism of the present invention is a saddle rotation support mechanism that rotatably supports the bicycle saddle between the tilted position and the riding position with respect to the bicycle body frame. Since the pivotable hook member holds the saddle at the riding position, the pivotable saddle can be held at the riding position by the hook member.
