Abstract

PROBLEM TO BE SOLVED: To secure the burglar preventive effect by obtaining two effects to use a stand and to lock the stand, in which a rod is projected between the spokes of a wheel to stop the rotation automatically when the single leg of the single-legged stand of a bicycle is lowered from the springing-up condition to the ground surface side, and at the same time, the locking is applied to maintain such a condition. SOLUTION: A link structure composed of four rods including a rod 4 and a rod 7 journalled rotatable to two surface 2 and (5) which are bent by making an obtuse angle symmetrically to the installing surface 1 to the body of the installing base of a single-legged stand respectively, and a rod 12 and a rod 8 connecting with the above rods respectively, is formed, and one end of a lock 14 is connected to the connecting point 13 of the rods 12 and 8 furthermore, while one end of a rod 15 inserted in the lock at the other end is installed to the rod 4. The rod 8 is made in the structure having a front end part 9 bent by making an obtuse angle with its main body 8 by making a shaft fulcrum 10 on the rod 7 as the border.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-leg stand having a lock function for preventing theft of a bicycle. 2. Description of the Related Art Conventionally, there are two types of bicycle stands, a two-leg stand and a one-leg stand. To prevent theft during use of the stand, be sure to attach and lock the lock separately. It was necessary to be careful. [0003] When using the one-leg stand by getting off the bicycle, the rod 4 as one leg of the one-leg stand is raised from the state where the rod 4 is flipped up to the ground side. By taking advantage of the fact that the lowering operation locks the bicycle wheel at the same time, it is necessary to save time and effort to lock the bicycle so that there is no danger of forgetting to lock. [0004] Each of the pivots is rotatably mounted on two surfaces 2 and 5 symmetrically forming an obtuse angle α with respect to a mounting surface 1 of the mounting base of the one-leg stand on the vehicle body. A link structure composed of four rods, the rods 4 and 7 and the rods 12 and 8 connected to them, respectively, is configured to move the rod 4 serving as the leg of the single-leg stand from the flipped-up state to the ground side. Due to the passive movement of the connecting fulcrum 13 between the rod 12 and the rod 8 caused by the link operation that occurs when the lock is lowered, the lock is locked by the rod 15 entering the inside of the lock 14. (A) Rod 4 as one leg of one leg stand
In the state in which the rod 4 is flipped up, the rod 4 is pulled toward the rod 7 by the lock lever 18 and the spring 22 and is held in the state shown in FIG. 1. And both are parallel to the ground, so that there is no hindrance to driving the bicycle.
This means that rods 4 and 7 are each
The relationship between the rods 4 and 7 is as shown in FIG. 3 corresponding to FIG. (B) When the rod 4 serving as the leg of the single-leg stand is lowered from the flipped-up state to the ground, the rod 4 is rotatably supported on the surface 2 of the mounting base.
, The rod 4 rotates along the surface 2 inclined at the obtuse angle α toward the ground, and the tip of the rod 4 lands on the ground. At this time, the relationship between the rod 4 and the surface 2 is as shown in FIG. 4 corresponding to FIG. (C) When moved as described in (b) above, the link structure composed of the rod 4, the rod 12, the rod 8, and the rod 7 is operated, and the fulcrum 13 where the rod 12 and the rod 8 are cross-connected is pushed up. The lock 14 whose one end is connected to the fulcrum 13 is simultaneously pushed up. At the other end of the lock, there is a rod 15 which can enter into the inside of the lock, supported by the rod 4, so that when the fulcrum 13 is pushed upward, it moves relatively into the lock 14. Therefore, the locking mechanism can be operated by the rod 15 entering the inside of the lock 14. (D) Since one end of the rod 15 is buffer-attached to the rod 4 by the attachment shaft 16 and the spring 17, the movement of the rod 15 that enters and exits the lock 14 can be smoothed. (E) The rod 8 cross-connected to the rod 12 at the fulcrum 13 is attached rotatably about the fulcrum 10 on the rod 7 and bends at an obtuse angle θ with the body 8 about the fulcrum 10. In the state where the rod 4 is flipped up and attracted to the rod 7 as shown in FIG. 1, the tip 9 of the rod 8 is positioned so as to overlap the rod 7. Rod 4
Is lowered to the side of the ground and its tip moves so as to land, a link mechanism of four rods of rod 4, rod 12, rod 8, and rod 7 is operated, and the rods 12 and 8 cross-connect. The fulcrum 13 is pushed upward, and the tip 9 of the rod 8 is moved from the position overlapping the rod 7 to the rod 7.
Travels to the right in a direction at right angles to it, which protrudes between the spokes of the wheel and stops the rotation of the wheel. Embodiments of the present invention will be described below. (A) The mounting base of the one-leg stand to be mounted on the bicycle body is perpendicular to the ground and fixed to the vehicle body with the surface 1 and the surface 2 bent at a constant obtuse angle α to the surface 1 and the surface 2 Symmetrically, it is made to have a structure composed of three surfaces 5 which are also bent at an obtuse angle α with respect to 1. (B) A rod 4 rotatable about a fulcrum 3 attached to the surface 2 of the mounting base of the single-leg stand and a rod 7 rotatable about a fulcrum 6 attached to the surface 5 of the mounting base are mounted. (C) A rod 12 rotatable about a fulcrum 11 on the rod 4 as an axis and a rod 8 rotatable about a fulcrum 10 on the rod 7 are cross-coupled at a fulcrum 13.
A structure in which the four rods of the rod 12, the rod 8, and the rod 7 perform a link operation is made. (D) The rod 8 described in (12) is formed so as to have a tip 9 that bends at an obtuse angle θ with the main body 8 at a fulcrum 10 on the rod 7. (E) One end of the lock 1-4 is connected to a fulcrum 13 at which the rod 12 and the rod 8 cross each other, and the link operation described in (c) is moved up and down passively. (F) One end of the rod 15 inserted into the lock 14 at the other end thereof is mounted on the rod 4 with a mounting shaft 16 and a spring 17 in a buffered manner, thereby raising and lowering the fulcrum 13 described in (e) above. Rod 1 for movement
5 make and smoothen the movement that changes the degree to which it relatively enters the lock. (G) When the rod 15 is inserted deeply into the lock 14, the lock is constructed so as to be locked, and when unlocked, the rod 4 which is the leg of the single-leg stand is flipped up, and the spokes of the wheels are spoken. At the same time, the distal end portion 9 of the rod 8 protruding therebetween is moved so as to be accommodated in a position overlapping the rod 7, and at the same time, the rod 15 returns from the state of being deeply inserted into the lock to the original state. The operation of dropping off the bicycle and lowering the rod 4, which is the leg of the single leg stand, to the ground side from the state of the bicycle to prevent the wheels of the bicycle from rotating at the same time. Therefore, it is possible to save the trouble of locking and to eliminate the danger of forgetting to lock by this one-time advantage.
