Description

    The present invention is a bicycle parking front wheel stabilizer that enables locking of a handle for stable parking and bicycle front brake operation.

    A conventional bicycle maintains the safety of traveling by braking the front and rear wheels during traveling, and is parked while standing by a rear arch-type stand or a single foot stand during parking.

    The conventional form of parking has the following problems. In the case of a normal arch-type stand, if the weight exceeds a certain amount when the front luggage bag is loaded, the bicycle loses stability and falls over. Also, when the infant chair is mounted on the front and the child is on it, the hand cannot be released from the handle.

    Next, in the case of a one-leg stand, when parking, the front wheels are directed obliquely and the vehicle body is also inclined obliquely, so that the front wheels are not stable depending on the terrain where the vehicle is parked, and the bicycle falls even with a slight impact. Also, when parked outdoors, it is difficult to fall down because of weak crosswinds. The present invention is intended to solve the above-mentioned drawbacks by locking the handle simultaneously with parking and simultaneously operating the brake to stop the front wheels to enable safe and reliable parking.

    According to the first and second aspects of the present invention, a locked portion that allows the handle to be locked in a straight direction toward a locked device having the locked portion, and a locked portion that can lock the handle at an oblique angle. The locking part having the locking part and the two locking parts, or the locking tool capable of locking the handle only at an oblique angle, is fixed to the lower part of the steering wheel so as to be rotatable. A ballast equipped with a function capable of simultaneously locking the handle and operating the brake is attached to the upper part of the hawk, and the front wheel is directed at either a straight or oblique angle by a lock that moves up and down in conjunction with the starter lever of the ballast. The handle is locked and the brake is operated at the same time to enable safe parking. When the handle is released, the brake is released at the same time, and the problem is solved.

    As described above, the present invention makes it possible to lock the handle straightly or at an oblique angle by one operation of the start lever with a simple operation, and the brake is also actuated simultaneously regardless of the straight angle or the oblique angle. Parking safety can be secured. Therefore, in the case of a bicycle with an arch-type stand, even if a large amount of luggage is loaded on the front luggage cage and a child chair is mounted on the front, an infant is placed on the bicycle and the hand is released from the handle, the bicycle is kept stable and secure parking In the case of a one-leg stand bicycle, the front wheel brake is activated and the front wheel is stopped even if the front wheel is parked at an oblique angle. Since parking can be prevented, stable parking is possible.

    In the present invention, all functions are concentrated on the start lever of the ballast via the connecting rod, so that the brake is activated at the same time as the handle is locked by one operation of the lever, the front wheel stops and the lever is held at the upper stop point. By holding and holding by the plate, reliable and stable parking is maintained, and if the handle lock is not released, the brake is operated and the bicycle cannot start, so the start in the handle lock state cannot occur . To start, if the holding plate is lightly swung to the right, the lever automatically descends to the bottom stop point and the handle lock is released. At the same time, the brake is also released for safe start and the ballast body Is a safe and reliable form as a structure that does not allow accidents due to breakdowns.

    An embodiment will be described below with reference to the accompanying drawings. FIG. 1 is a front view of the ballast, FIG. 2 is a left side view, and FIG. 3 is a right side view, both of which are before the stabilizer operates. That is, in each figure, the starting lever 6 is lowered to the lower stop point and is held at the lower stop point by the holding plate 9, and the locking tool 4 is lowered from the locked portion by the elastic force of the return spring, and the handle 5 is unlocked. It is. Also, the connecting rod 7 linked to the lever 6 stops operating together with the wire pulling lever 8, the ballast wire 14 is loosened, the brake rubber 26 is released from the rim 27, the brake is released, and the handle 5 is completely free. is there. Next, the operation mode of the stabilizer will be described with reference to the drawing. First, in the front view of FIG. 4, the locking lever 4 is interlocked with the start lever 6 ascending to the upper stop point. The handle 5 is locked in the straight direction and the wire pulling lever 8 interlocked with the connecting rod 7 simultaneously interlocked pulls the ballast wire 14 to actuate the front wheel brake 20, and the start lever 6 is The bicycle is locked and held by the holding plate 9 at the stop point, the handle of the bicycle is locked, the brake is also operated, and the front wheels are kept stopped. Next, in the left side view of FIG. 5, the starting lever 6, which has been moved to the right by swinging the holding plate 9, is held by the holding plate 9, and the locking device 4 is covered by the front luggage hook 3. The handle 5 is locked through the locking portion. Next, in the right side view of FIG. 6, the front wheel brake 20 pulled by the ballast wire 14 is activated, the brake rubber 26 presses against the rim 27, and the front wheel is stopped. Also in the plan view of the next FIG. 7, the handle 5 is locked in the straight direction and the bicycle is in a safe and secure parking state. When starting, if the holding plate 9 is swung to the right, the start lever 6 is lowered to the bottom stop point, the handle 5 and the front wheel brake 20 are automatically released simultaneously, and the bicycle can start safely. The above is the embodiment of the bicycle of the arch type stand.

    Next, an embodiment in the case of a single leg stand will be described with reference to the drawings. First, the form before the operation is exactly the same as the case of the arch type stand, and is the same as the above description. Therefore, the drawings and the description when not operating are omitted, and will be described with reference to the drawings from the time of the parking operation. First, in the front view of FIG. 8, if the holding plate 9 is actuated to raise the starting lever 6 to the upper stop point and point to the left of the handle 5, the handle 5 is locked at an oblique angle by the locking tool 4. The ballast wire 14 is pulled by the connecting rod 7 interlocked with the front, the front wheel brake 20 is activated, and the front wheel is stopped. The activation lever 6 is locked and held by the holding plate 9 at the upper stop point, and is in a safe and secure parking state. Next, in the left side view of FIG. 9, the activation lever 6 is held by the holding plate 9 at the upper stop point, and the interlocking locking device 4 penetrates the locked portion of the front luggage hook 3 and handles 5. Is locked. In FIG. 10, the stabilizer wire 14 is pulled, the front wheel brake 20 is operated, the brake rubber 26 presses against the rim 27, and the front wheel is in a stopped state. Next, as shown in the plan view of FIG. 11 or FIG. 12, the locking device 4 passes through the locked portion 2 of the front luggage rack hanging device 3, and the handle 5 is locked at an oblique angle and is in a completely parked state. . The above is the parking state of the bicycle with the one-leg stand, and the operation of the handle 5 and the front wheel brake 20 is the same as that of the first embodiment. I can do it. As described above, the combination of FIG. 8, 9, 10, 11 or the combination of FIG.
