Claims6
A safety latch means for storage compartments and similar enclosures having an access opening therein comprising:
- a closure;
- biasing means for moving said closure means to the closed position relative to said opening when unattended;
- and automatically engaging safety latching means including at least two extension means disposed generally parallel to each other;
- means for biasing said extension means apart;
- outwardly disposed, beveled in configuration, locking hook means on the outer end of said extension means;
- a latch opening associated with said enclosure for receiving said locking hook ends of said extension means;
- and inwardly projecting flange means disposed adjacent at least a portion of the periphery of said latch opening for interengaging said locking hooks whereby, when the closure means biasingly moves to the closed position, said locking hooks will pass through said latch openings and engage said interior flanges thereby interengagingly locking the same and requiring inward movement of said extensions to disengage said hooks from said flanges, squeezing movement to dispose said extensions substantially adjacent each other to allow said latching hooks to pass through said latch opening, and outward movement to remove said extensions and their associated locking hooks from said opening when said closure is opened to give access to the interior of said enclosure.
