LOCK FOR KNOCK-DOWN STORAGE RACK

摘要

The locking connector interconnects a shelf supporting beam to an upright of a knock-down storage rack. The locking connector includes a plunger which is connected to the connector and which is slidable between locking and unlocking positions. The plunger, when in the locking position, is within one of a number of openings formed in the upright with resulting locking of the upright to the connector. When the plunger is in the unlocking position, it is outside the opening thus allowing the upright to be separated from the connector. The first embodiment of the locking connector includes a resilient rod which is biased into a groove formed in the shank of the plunger when the plunger is in the locking position. The rod prevents the plunger from moving from the locking position unless a force, opposed to the bias of the rod, is applied to the plunger to cause the rod to withdraw from the groove. The second embodiment of the locking connector includes a housing which surrounds and protects the plunger. The third embodiment includes a guard for protecting the housing when the plunger is in the locking position.
