An improved keeper lock for a zipper-type slide fastener. The lock includes a barrel assembly of a tubular barrel and an anvil fixed to and projecting readily from the barrel, the anvil adapted to receive the slide fastener when the fastener is moved to its closed position. A key operated lock assembly is telescopically and rotatably received in the barrel for limited axial sliding movement. A keeper arm is fixed to and projects radially from the lock assembly adjacent to a proximal end of it and the lock assembly and keeper arm are capable of both angular rotation and axial movement so that it may assume a fully telescoped locked position with the keeper arm closely overlying the anvil for confining the slide fastener between the keeper arm and the anvil. It may also assume an unlocked position wherein the keeper arm overlies the anvil and is spaced apart therefrom. The improvement includes means to align the keeper arm over the anvil when the keeper arm is in a partially telescoped and unlocked position such that it may assume a fully telescoped locked position with the keeper arm closely overlying the anvil by applying an axial force to the keeper arm. The alignment means includes an upstanding finger arm, a slidable locking bolt which engages a groove in the barrel.

In a keeper lock for a zipper-type slide fastener the lock including a barrel assembly of a tubular barrel and an anvil fixed to and projecting radially from the barrel, the anvil adapted to receive the slide fastener when the fastener is moved to its closed position, a key operated lock assembly telescopically and rotatably received in the barrel for limited acial sliding movement therein and a keeper arm fixed to and projecting radially from the lock assembly adjacent to a proximal end thereof, the lock assembly and keeper arm being capable of both angular rotation and axial movement so that it may assume a fully telescoped locked position wherein the keeper arm closely overlies the anvil for confining the slide fastener between the keeper arm and the anvil, an intermediate partially telescoped and unlocked position wherein the keeper arm overlies the anvil and is spaced apart therefrom, and a partially telescoped and unlocked position wherein the keeper arm is swung to one side so that it assumes a laterally removed position with respect to the anvil so that the slide fastener is accessible for manipulation, a locking bolt carried by the lock assembly and adapted for locking engagement with the barrel when the lock assembly assumes the fully telescoped locked position to maintain the lock assembly in the locked position, a lock cylinder in the lock assembly and movable between locked and unlocked positions, and a key and tumbler mechanism for controlling the operation of the cylinder, the lock cylinder, when in its unlocked position, serving to withdraw the locking bolt from its locking engagement with the barrel, the improvement comprising: alignment means for positioning the keeper arm over the anvil when the keeper arm is in the intermediate partially telescoped and unlocked position so that the keeper arm can assume the fully telescoped and locked position by pushing the keeper arm axially towards the anvil, said alignment means comprising a protruding finger carried by the lock assembly and a receiving groove portion in the barrel, the receiving groove portion adapted to receive in locking relationship the protruding finger when the keeper arm is rotated to a position overlying the anvil, said protruding finger being engaged by spring means for pushing the finger radially outward against the barrel, the finger operatively connected to the key operated lock assembly so that operation of the key and tumbler mechanism causes withdrawal of the finger from engagement with the groove portion in the barrel.
