Abstract

The lock body of a motorcycle disk brake lock has a first side, a second side adjacent to the first side, and an open slot of a predetermined depth and extending into the lock body, which is divided into a first portion and a second portion in which a locking device is disposed. The locking device is provided centrally with a locking bolt. When the locking device is in an unlocking state, the locking bolt is located at a first position. When the locking device is in a locking state, the locking bolt is located at a second position. The first portion is provided with an open end adjacent to the open slot and located in a locking hole coaxial with the locking bolt. The first portion is provided with at least one through hole having one end joining obliquely with the locking hole and having another end located in the side which is not adjacent to the open slot.

Claims

1. An improved motorcycle disk brake lock comprising:

a lock body having a first side, a second side adjacent to said first side, and an open slot of a predetermined length and extending into said lock body such that said open slot is perpendicular to said first side, said lock body being divided by said open slot into a first portion and a second portion; and

a locking means disposed in said second portion and having a locking bolt extending outwards from a center thereof, with said locking bolt being located at a first position at such time when said locking means is in an unlocking state, said locking bolt capable of being caused to move from said first position to a second position so as to seal off an open end of said open slot and to pass through one of a plurality of heat radiating holes of a motorcycle disk brake received in said open slot;

wherein said first portion of said lock body is provided with a locking hole having an open end adjacent to said open slot and coaxial with said locking bolt and said locking hole; and

wherein said first portion of said lock body is provided with at least one through hole having one end joining obliquely with said locking hole and having another end that is located in a side other than a side of said open slot,

wherein dust is pushed out of the locking hole by way of the through hole when said locking bolt is moved into said second position.

2. The improved motorcycle disk brake lock of claim 1 wherein said second portion is wider than said first portion.
