Abstract
A bag fastener with a fixing piece includes a locking piece insertable into a fastening body, such that the fastener does not unlock in use. When the unlocking the fastener from a locked condition, the locking piece is released and unlocked from the fastening body. Accordingly it is possible to use the fastener safely because it is not unlocked in use by natural forces, in contrast with known fasteners which are unlocked in use by natural forces acting on the fastener.
Claims5
A lockable fastener comprising:
- a fastening body;
- an insert for mating with said fastening body;
- and
- a locking piece slidably and removably engaged with said fastening body,
- said fastening body including an inlet opening for receiving said insert therein, a pair of longitudinal guide holes formed in an upper surface of said fastening body, a fixing projection upwardly projecting from the upper surface of said fastening body and between the pair of longitudinal guide holes, and a pair of deformable pushing members formed along longitudinal sides of said fastening body and each with a first end fixed adjacent the inlet opening and a second pushing end terminating at a position in lateral correspondence with the pair of longitudinal guide holes and the fixing projection;
- said insert including a pair of longitudinally extending leg members, each having toothed ends for engaging with a portion of the fastening body, and a central supporting member extending parallel to and laterally between the leg members;
- and
- said locking piece including a pair of fixing legs snap fit into the pair of longitudinal guide holes, respectively, and slidable within a longitudinal length of the guide holes, and an upper gripping surface for manually actuating said locking piece,
- wherein positioning of said locking piece at ends of the longitudinal guide holes toward the inlet opening of said fastening body wedges the fixing legs between the longitudinally extending leg members and the central supporting member thereby locking said fastener, and wherein position of said locking piece at ends of the longitudinal guide holes away from the inlet opening of said fastening body releases the fixing legs from between the longitudinally extending leg members and the central supporting member thereby unlocking said fastener.
