Description

   The present invention relates to a bicycle overturn prevention device that works in conjunction with a brake that avoids the danger of overturning when the bicycle is suddenly braked.

   There may be a habit where the elderly or the elderly must stop suddenly while riding a bicycle. In such a case, it is often the case that a sudden brake is applied and the balance is lost to fall.

    Many elderly and senior citizens were injured when the bicycle fell while driving, and when they were surprised and applied the brakes, they were most likely to fall.

In the event of a habit of having to stop suddenly while the elderly or elderly ride on a bicycle, we investigated a device that does not fall down without breaking the balance even if sudden braking is applied. Neither non-patent literature was found.

  The problem to be solved is a device that uses a brake and at the same time prevents a fall so that it does not fall and get injured in such a situation. This need is linked to development, and there is a need for safe and secure bicycles.

The present invention is designed so that when such an elderly person or an elderly person rides on a bicycle and must stop suddenly while driving, the bicycle will not fall down without breaking the balance even if the brake is applied suddenly. The brake and the fall-preventing device are simultaneously activated by one brake operation to solve the fall-prevention.

  The present invention includes a rectangular substrate portion, a mounting plate portion formed with at least two mounting holes integrally formed on the left and right ends of the substrate portion when viewed from the front, and a pair perpendicular to the left and right ends of the substrate portion when viewed from the front. A rotating part mounting part formed of a rotating body support plate part provided with a formed shaft insertion hole, a three-dimensional stand for preventing overturning, a rotating part formed integrally with the rotating part, and a shaft member on the upper part of the rotating part An upper fitting surface provided with a shaft fitting insertion hole and a wire attachment portion to be fitted, the wire attachment portion and the brake operation portion being connected via a wire, and formed on the back surface of the upper portion of the rotating portion, and the substrate The upper pressing surface so that the inclination angle formed by the fulcrum part that is in sliding contact with the substrate surface of the part, the perpendicular of the three-dimensional stand of the rotating part and the upper pressing surface with the fulcrum part as a base point is an obtuse angle Forming the rotating body support plate portion with the shaft hole and the rotation The rotating body configured by pivotally supported to the shaft hole in the shaft member, a bicycle fall prevention device for a most important feature that the mounting the mounting member to a predetermined position of the bicycle front wheel both Hawk.

  When the driver pulls the brake lever of the bicycle fall prevention device of the present invention, the wire attachment portion of the rotating portion of the present invention is pulled upward simultaneously with the brake, and the rotating portion is centered on the axis of the rotating portion, Since the fulcrum on the back surface contacts the substrate surface of the substrate part and slides in the rotation direction, when the three-dimensional stand for preventing overturning opens to the outside of the wheel and the brake is pulled up to the maximum, the fulcrum on the back surface of the rotating part is Since it slides on the substrate surface of the substrate and moves in the rotation direction, it rotates until the upper pressing surface of the rotating body comes into contact with the substrate surface of the substrate portion, and stops rotating by contacting the substrate surface. Accordingly, since the three-dimensional stand for preventing the fall is appropriately opened and stopped in the outward direction of the bicycle wheel, there is an advantage that the support rod touches the ground at the position and can prevent the instantaneous fall.

  In FIG. 3, 5 indicates a mounting plate portion, 6 indicates a rectangular substrate portion, and 7 indicates a rotating portion mounting portion 8 constituted by a rotating portion support plate portion. A mounting plate portion 5 for attaching the rotating portion mounting portion 8 to each of the left and right ends in front view of the substrate portion is integrally formed. The mounting plate portion 5 is provided with two or more mounting holes 12 on each of the left and right sides. It is desirable that the mounting plate portion 5 has a curved shape that conforms to the outer shape of the bicycle front wheel hawk to which the mounting plate portion 5 is attached, for example, a hawk shape such as a cylindrical shape or an elliptical cylindrical shape. The rotating portion mounting portion 8 is formed with a pair of rotating body support plates that are vertically formed on the left and right ends of the substrate portion 6 when viewed from the front. The rotating portion mounting portion 8 is provided at the center portion so that the shaft hole 15 through which the shaft member 16 is inserted is located below the rotating portion shaft hole.

The rotating part of the present invention is a shaft hole and fixed with a shaft, but is a rotary type bearing in which a rolling member such as a ball bearing is embedded in the shaft hole of the rotating body.

The present invention may be a three-dimensional stand in which a rotating tool is attached to the grounding portion at the tip of the three-dimensional stand.

    The bicycle overturn prevention device of the present invention can be a stand and a rotating body part whose exterior is decoratively designed.

   In this embodiment, the left and right forks holding the front wheel of the bicycle, the tip of the three-dimensional stand for preventing the fall is mounted at a position at least 5 cm away from the ground contact point of the bicycle wheel, The bottle was inserted into the mounting hole of the plate portion, and after passing, it was fastened with a nut to attach the mounting plate portion to the front wheel fork.

A partial cross-sectional view 4 showing a partial cross section of the side surface of the substrate portion of the rotating body portion and the rotating portion mounting portion for explaining the operating principle of the bicycle overturn prevention device of the present invention was created. As can be understood from this figure, the fulcrum, the emphasis, and the power point are shown, and the operation of rotating using the lever principle will be described. That is, when the driver pulls the brake lever 10 in the bicycle fall prevention device of the present invention, an emphasis is added to the wire attachment portion 3 of the rotation portion of the present invention simultaneously with the brake wire 11, and by pulling the wire 4 upward, The priority position on the wire attachment portion 3 of the rotating portion 17 moves in the direction of arrow a in FIG. As a result, the rotating part rotates in contact with and slides on the substrate surface 26 of the substrate part around the axis of the rotating part as a fulcrum on the back surface of the rotating part. The force point at the tip rotates in the direction of arrow b in FIG.
Therefore, the three-dimensional stand 2 is opened to the outside in the direction perpendicular to the wheels, and the upper pressing surface 25 on the upper surface from the fulcrum portion on the rear surface of the rotating portion is made to be a substrate of the substrate by pulling the brake lever fully without leaving a margin. The stand is brought into contact with the surface 26 and stopped at a predetermined position outside the bicycle wheel. The stand opening position 23 in FIG. 2 illustrates one embodiment of the predetermined position in the outward direction of the bicycle wheel. When the brake lever is released, the wire is also released from the tension and relaxed, so that the stand rotates by its own weight and returns to a direction substantially perpendicular to the ground.

When the brake lever is fully pulled, the upper pressing surface above the fulcrum part on the back of the rotating part comes into contact with the board surface 26 of the board and stops the stand 2 at a position where it stands on the outside of the bicycle wheel. Since the stand also touches the ground at that position, there is an advantage that the stand 2 can function like a cane and can prevent an instantaneous fall. Therefore, during operation, when the brake is about to fall using the brake, by operating one brake lever, the brake and the device of the present invention operate simultaneously, the stand stands, and avoids a sudden momentary fall. be able to.

Since the present invention operates only when the brake is used, it follows the front wheel when driving without using the brake. Therefore, there is no trouble in operation during operation, and there is no trouble in operation.
Since the present invention can be mounted on a conventional bicycle, it can be used without any change from the conventional bicycle operation.
When the vehicle is stopped, the present invention can be stored in a predetermined position on both sides of the bicycle front wheel hawk, so that it is stable.
The stand storage position 24 in FIG. 2 illustrates one embodiment of the position where the bicycle wheel is stored.

    The present invention can be used regardless of age or gender, can be used by many bicycle enthusiasts, and can be produced at low cost industrially, and can be attached to not only new cars but also old bicycles as parts.
