Description

The present invention relates to a bicycle handle stopper that locks a front wheel so that it does not move when a hand is released from the handle and a stand is hung.

When you park a bicycle with a heavy object in the front of the bicycle, or when you park with a child using an auxiliary chair for children, the handle will bend if you try to release the handle and hang the stand. So, to prevent falling, hold the handle firmly with one hand, lift the saddle or the rear cargo bed with one hand and hang the stand. Similarly, when carrying luggage or a child on the bicycle in the front of the parked bicycle, the front wheel freely turns to the left and right, and there was a risk of the bicycle falling over due to instability. In addition, if the bicycle was parked with the handle bent, the front wheel could rotate and fall over even when a gust of wind blows or the bicycle is parked on a sloping ground.

For this reason, conventionally, the handle lock device that locks the rotation of the handle and the stand are connected by a wire, and when the stand is raised, the wire is pulled, and the lock lever of the handle lock device is operated to lock the handle. Some lock levers are released when the stand is flipped up (Patent Document 1).

However, in this structure, when a heavy object is parked in the front basket, or when a child is parked with a child auxiliary chair, the saddle or the rear loading platform is lifted before the stand is hung. There is a risk that the front wheels will rotate. Further, this handle lock device has a drawback that it is necessary to process ratchet teeth and stopper teeth on the handle post, and cannot be attached to the bicycle being used later.

For this reason, the inventor provides a lock shaft that protrudes and retracts by operating the knob on the handle post, and attaches a positioning plate having a lock hole to a cage mounting bracket for mounting the front cage above this, and raises the lock shaft. As a result, a bicycle handle stopper (Patent Document 2) has been developed in which the front end of the lock shaft is inserted into the lock hole of the positioning plate to lock the car mounting bracket so that the front wheel does not move.

However, this handle stopper has a problem that the number of parts is large, the processing is complicated, and the manufacturing cost is high. In addition, since the case with the knob operating part is attached to the handle post lower than the handle, it will bend forward each time it is operated, and the positioning plate must be separately attached to the basket mounting bracket, making assembly work cumbersome. there were.
