In the case of a long shackle lock, the end portions of the lock shackle are inserted into housings in a lock body. When this happens, they act on lock control sleeves pushing them out of a lock influencing position into a lock releasing position. The lock bolts move into the engaged position, i.e. in engagement with engagement surfaces on the end portions. The lock cylinder which controls the lock bolts moves into its basic position. The key can be withdrawn. To undo the lock, the lock cylinder is turned into a lock opening condition by the key which will then have been re-inserted. When this happens, the lock bolts are retracted into a disengaged position. The control sleeves then push the end portions at least partially out of the housings. The control sleeves move into the bolt influencing position. Therefore, the lock bolts remain in the disengaged position until the end portions are again inserted into the housings (FIG. 1). To close the lock, all that is needed is to insert the shackle arm end portions into the housings whereupon the key can be withdrawn at once without having been rotated first. The key can only be withrawn after the end portions have been inserted into the housings until they reach the closed position and have been interlocked.

A shackle lock, especially with a long shackle, comprising a lock body (10) and a locking shackle, the end portions (4) of the shackle arms being adapted to fit into respective shackle arm housings (42) until a locked position is reached (FIG. 1), and being completely seaparable from the lock body (10) by withdrawal of the arm end portions (40) from the housings (42) (FIG. 8), at least one lock bolt (32) being furthermore guided for movement in the lock body (10) and being pretensioned by biassing means (36) in the direction of an engaged position (FIGS. 1 and 2), so that after the arm end portions (40) have been pushed into their locked position inside the arm housings (42), they move into the engaged position (FIGS. 1 and 2), engaging thereby into a bolt engagement surface (48) of at least one arm end portion (40), so preventing withdrawal of this arm end portion (40) from the associated arm housing (42), there being furthermore provided inside the lock body (10) a key-operated bolt withdrawal mechanism (20) which is connected by a gearing (28, 34) to the lock bolt (32) and which can by means of the key be moved against the action of the biassing means (36) from a basic state (FIGS. 1 and 2) corresponding to the engaged position of the lock bolt (32) and in which the key can be inserted and withdrawn, into a lock-opening state (FIG. 9) which necessarily produces a disengaged position of the lock bolt (32), characterised in that there is in the shackle arm housing (42) a bolt control member (46), which, subject to spring pressure (44), bears on the arm end portion (40), so that when the lock bolt (32) is moved out of the engaged position (FIGS. 1 and 2) and into the disengaged position (FIGS. 8 and 9), it causes a displacement of the arm end portion (40) out of the locked position and into the direction of separation from the lock body (10) (FIGS. 8 and 9) and thereby out of a bolt release position (FIGS. 1 and 2) into a bolt influencing position (FIGS. 8 and 9) in which it prevents the return of the lock bolt (32) to its bolt engaged position (FIGS. 1 and 2) (FIGS. 8 and 9).
