Abstract
Abstract A compact portable locking device designed primarily to be utilized in conjunction with coats, bicycles, skis and the like is disclosed. The device takes the form of a housing having two or more internal chambers. The housing has an upper hollow engaging cap portion and a lower complementary body portion where the cap portion and body portion together form the internal hollow volume having two or more chambers. One chamber includes the locking mechanism, a receptacle cavity which is accessible within the internal chamber or at a point through the housing, and an active locking element. A flexible securing member having one end permanently affixed to the lock unit within the chamber and the other end of the member having a pin which is adapted to enter the receptacle cavity of the lock unit and to interlock thereon. The second internal chamber is useful as a storage chamber for the flexible securing member when the lock is not in use. The flexible securing member is looped about or through a stationary object, such as a pole, or to a large object, such as a chair, and through the object to be secured and locked. The flexible securing member is preferably, a link chain or flexible metal cable. The lock can be easily opened by a key or a combination at a later time when desired.
