JPH1120759A - Storable handlebar fitted with antitheft function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a handlebar from being caught by a handlebar of a neighboring bicycle and facilitate storing thereof, by fixing and locking up the handlebar with it put in the same direction as a front wheel at the time of parking by providing a horizontally rotatable revolution body fitted with a fixing function on a stem of a middle part of the handlebar. SOLUTION: A horizontally rotatable revolution body 12 is provided on a stem 1 of a middle part of a handlebar. This revolution body 12 is equipped with a fixing function such as a lock 11 or a safety lock, and the handlebar is thereby fixed and locked up. In such a structure, the handlebar is fixed by the lock 11, the safety lock, or the like present in the revolution body 12 during travel. At the time of parking, the lock 11, the safety lock, or the like present in the revolution body 12 is released and the handlebar is rotated horizontally until it faces to the same direction as a front wheel and then fixed and locked up. Bringing a bicycle into and out of a bicycle parking area is facilitated as the handlebar is not caught by a neighboring bicycle while bicycle parking space can be made smaller, by rotating and storing the handlebar in this way at the time of parking.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle parking and anti-theft function of a bicycle.

[0002]

2. Description of the Related Art In the prior art, a bicycle handle is fixed.

[0003]

Conventionally, when parking a bicycle, it is inconvenient to hook a handle or the like on an adjacent bicycle. Therefore, a technical problem of a bicycle having a structure convenient for storage and having an anti-theft function arises, and an object of the present invention is to solve the problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above object, and has a revolving body with a fixed function which can be rotated in the horizontal direction on a stem at the center of a handle of a bicycle. A structure that can be fixed and locked when the handle is in the same direction as the front wheel, and a revolving body with a fixing function that can be rotated in the vertical direction is provided on a stem at the center of the handle of the bicycle, and the handle is vertically oriented. A bicycle with a structure that can be fixed and locked when needed, and a structure that has one or several foldable joints with a fixing function inside the brake lever of the handlebar and can be folded when parking bicycles is there.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a central portion of a handle is equipped with a rotatable revolving body or is a joint that can be folded.

According to the first aspect of the present invention, there is provided a structure in which a revolving body having a fixing function rotatable in a horizontal direction is provided on a stem at the center of a handle of a bicycle, and the handle can be fixed and locked when the handle is in a front-rear direction.

According to a second aspect of the present invention, there is provided a structure in which a revolving body with a fixing function rotatable in a vertical direction is provided on a stem at the center of a handle of a bicycle, and the handle can be fixed and locked when the handle is up and down.

According to the third and fourth aspects of the present invention, one or several foldable joints having a fixing function are provided inside the brake lever of the handlebar, and the foldable joint can be folded and fixed and locked when the bicycle is parked. Construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 is an explanatory view of a handle portion of a general bicycle, in which a stem (1) and a handlebar (2) are fixed both during running and parking. Also stem (1)
And the head tube (6) are also fixed.

FIGS. 2A and 2B are diagrams of the vehicle according to the first aspect of the present invention during traveling (a) and during bicycle parking (b). During traveling, the steering wheel is fixed by a key (11) on the rotating body (12), a safety lock, or the like. When parking a bicycle, the key (1) on the rotating body (12)
1), safety lock, etc. are released, and the handle is rotated horizontally until it is in the same direction as the front wheel, and FIG.

FIGS. 3A and 3B are diagrams showing the state of traveling (a) and the state of parking (b) according to the second aspect of the present invention. During traveling, the steering wheel is fixed by a key (11) on the rotating body (12), a safety lock, or the like. When parking a bicycle, the key (1) on the rotating body (12)
1) or safety lock is released, and the handle is rotated vertically until it is in the same direction as the front wheel to fix and lock.

FIG. 4 is a front view of the vehicle according to the third aspect of the present invention during traveling (a) and during bicycle parking (b). During traveling, the steering wheel is fixed by a key (11) on the rotating body (12), a safety lock, or the like. When parking a bicycle, the key attached to the stem (1
1) is released, the fixing cover (14) is opened, and the handlebar (2) is bent downward. Further fixed cover (14)
Close and lock securely. In this case, it does not matter in the direction in which the handlebar is bent. Various methods can be considered for fixing and bending the handlebar.

The present invention can be variously improved without departing from the spirit of the present invention, and it is natural that the present invention extends to the modified one.

[0014]

According to the present invention, since the handle and the like are minimized by rotating and storing or folding the handle when parking the bicycle, the handle is not caught by the next bicycle and is convenient for putting in and out of the bicycle parking lot. Bicycle parking space can be reduced. In addition, by locking and locking when rotating or storing, even if stolen, the steering wheel cannot be operated and driving cannot be performed. Therefore, the probability of encountering theft is reduced.
