Abstract

An improved anti-theft locking device permanently and quickly securable to various objects by self-contained concealed fastener means sized to have an interference locking fit with a mounting bore such as the interior of a cycle handlebar or the like. The locking bolt may be secured to one end of a flexible cable normally stored and concealed in the handlebar and the major length of which is withdrawable therefrom when used to lash the cycle to a fixed object. The outer end of the cable is fixed to the locking bolt and this bolt is invertable so that either end is insertable into the locking mechanism depending upon whether or not the cable is in use. A variant embodiment of the invention is readily installed between a door and its casing and may utilize a linkage in lieu of a flexible cable as a part of the anchor subassembly.

A locking device permanently securable to one end of a cycle handle bar and adapted to lock the cycle to a fixed object when not in use comprising, an elongated tubular main body having generally radially disposed strong but flexible protrusions projecting therefrom and having a sharp edge extending transversely of their free outer ends, said protrusions being sized to have a forced telescopic fit with the interior wall of a handle bar upon insertion axially therealong with said sharp edges biting into said wall to positively prevent withdrawal of said lock device, combination lock mechanism on the outer end of said lock device including a locking bolt lockable within the outer end of said main body when either end thereof is inserted into the outer end of said tubular main body, flexible tie means slidably supported axially of said tubular main body and normally storable within a cycle handle bar when not in use, means preventing full withdrawal of said tie means from said lock device, the outer end of said tie means being anchored to said locking bolt, and a seating groove for said tie means along one side of said locking bolt to seat a length of said tie means when said tie means is in use to lock a cycle to a fixed object.

A cycle anti-theft device permanently installable in one end of a cycle handle bar, said device having a tubular main body having means for permanently securing the same to one end of a cycle handle bar and provided at the other end thereof with a combination lock means having a removable locking bolt, flexible tie means extending loosely through said main body and including means at one end preventing full withdrawal of said tie means from said main body and having the other end thereof fixed to said locking bolt, said locking bolt being lockable in assembled position to said locking device when either end is inserted into the outer end of said tubular main body, and seating passage means for said tie means along the exterior of said locking bolt to seat a midlength portion thereof when said tie means is in use to lock a cycle to a fixed object.
