Description

  The present invention relates to a bicycle handle lock that allows a handle post to be locked to a vertical cylinder portion of a bicycle, and enables locking operation from the other end surface of a lock case main body with a key hole protruding on one end surface. This eliminates the need for a key lock operation.

In conventional bicycle handle lock locks, as in Patent Documents 1 and 2, the lock case main body has a keyhole of the built-in locking mechanism protruding from one of the left and right or upper and lower end faces of the lock case main body, and from one direction with the keyhole. those to unlock or lock by a key operation is generally used. Also, as in Patent Document 3, a so-called one-key two-lock type bicycle in which two locks, a lock for locking a tire and a handle lock lock, are attached to a bicycle and locked and unlocked with a common key. There is a locking device.

Japanese Unexamined Patent Publication No. 2000-16361 (for example, see page 1 and FIG. 1) Japanese Patent Laid-Open No. 2000-8675 (for example, see page 1 and FIG. 1) JP 2003-82906 A (see, for example, page 1 and FIG. 1)

According to the above-mentioned prior application, all have a common point that a key must be used for locking the handle lock.
Therefore, when there is an emergency or when going to work, it is necessary to take out the key you have and insert the key you inserted into the keyhole and lock it. In the dark, there was an inconvenience in use that it took time to lock the handle lock.

  From the above, the problem to be solved by the present invention is to make it possible to lock a bicycle handle lock lock by an operation close to one touch without using a key, and to save the trouble of locking.

Therefore, in order to solve the above-described problems, the present invention provides a bicycle handle lock lock for locking a handle post to a vertical cylinder portion.
