Description

  The present invention relates to a bicycle ring lock, which can be unlocked by pressing a seesaw-type button pivotally attached to the lock body, and is automatically locked by an auto-lock plate when the bag is slid to the locked position. The unlocking mechanism can be reset with a push button.

  Conventionally, in this type of bicycle ring lock, the buttons for pressing the PIN code etc. are small and the distance between the buttons is small, so it may be pressed at night or in the dark, women with long nails, gloves in winter, etc. It was inconvenient to unlock the hand using a button.

  Conventionally, in this type of bicycle ring lock, because of the mechanism of the unlocking part, even if the bag is in the locking position, the unlocking part is in the unlocking standby state, so it is necessary to always press one of the buttons after locking. Yes, sometimes I forgot to press the button and was left in the unlocked standby.

  Conventionally, in this type of bicycle ring lock, due to the mechanism of the unlocking part, in order to reset, the button on the back of the lock body is pushed up, the button on the front is returned to its original position, or a reset knob is provided. It was inconvenient to visually check at night and in the dark, such as resetting by rotating multiple times to the mark.

From the above, the problem to be solved by the present invention is that a large button that is not inconvenient for visual confirmation can be used to detect and confirm the number of times the button is depressed, which is an unlocking operation, and automatically when locking. It is another object of the present invention to provide a bicycle ring lock in which the unlocking mechanism is locked and the reset operation can be performed without the need for visual confirmation when unlocking.

  Therefore, in the present invention, the button that pushes down the unlocking mechanism is a single large button, and the button is pivotally attached to the lock body like a seesaw, and for example, three gears are fixed to the lower part of the button. The unlocking mechanism is placed, and one end of the button is pushed down and the top of the gear stopper of the unlocking mechanism is suspended to rotate the gear, and the gear stopper restores its shape and simultaneously locks the gear. Then, by detecting the reaction and confirming the number of depressions, the other gear stoppers are also suspended by the button to bring all the gears to the unlocked position, and finally unlocked by pressing the unlocking button. During locking, when the rod slides in the lock body to the locked position, the protrusion on the outer periphery of the rod engages with the auto-lock plate pivotally supported by the lock body, and one gear of the gear is engaged. To unlock the unlocked position. The 構部 the locked state, at the time of unlocking is in bicycle seesaw button Lock ring can begin reset unlocking operation of the open lock mechanism simply by pressing several times the button reset.

  According to the present invention configured as described above, the position of the seesaw-type button is made as large as possible on the surface of the lock body, so that the position can be easily confirmed, and the push-down operation by the fingertip is facilitated, and the nail is extended. The unlocking operation can be easily performed even with a thick fingertip or glove. Further, since the button is a seesaw type, it is difficult to predict the order of pressing and the number of times of pressing, and this is effective in preventing theft. The auto-lock mechanism avoids the risk of theft due to forgetting to press the button after locking. In addition, because it can be reset by a push button, a bicycle ring lock can be produced that can be unlocked without having to be visually confirmed or bent when it is unlocked at night, in the dark, or in the rain.
