Abstract A safety lock for enclosures having a first lock portion attached to the first of two members to be locked together. This lock portion includes a bolt rotatable for accomplishing a locking function. The bolt has a head of non-conventional shape. A second lock portion is attached to the other of the members to be locked together and is engageable by the bolt. The first lock portion includes a protective wall peripherally surrounding the bolt head and open at its outer end. The surrounding wall defines a socket which is at least as deep as the thickness of the bolt head to prevent side engagement of the bolt head and which is of greater diameter than the bolt head to permit removal of the bolt by a special wrench inserted through the open end of the protective wall. The second lock portion in one embodiment includes a pin having a radial notch intermediate its ends engageable by the bolt to provide a more positive lock. Also, in some embodiments, the pin projects beyond the first lock portion and receives a padlock or the end of the pin may project into a socket member to conceal the end thereof. A further locking feature may employ a spring acting on one of the lock portions with a force great enough to prevent children from opening the lock even though other fastening means of the lock are released.
An enclosure with a double safety lock comprising a. an upright support member, b. an enclosure, c. means supporting said enclosure on said support member, d. said upright support member and enclosure being disposed with portions thereof in vertical overlapping relation, e. an outwardly extending eye member on said enclosure disposed in an overlapping portion of said support member and enclosure, f. a slot in said support member arranged to receive said eye member therethrough, g. said eye member in projecting through said slot being arranged to receive an exterior locking device for providing a first lock connection between said support member and enclosure, h. and a bolt extending through said support member, i. said bolt having head engagement with said support member and threaded engagement with said enclosure to provide a second lock connection between said support member and enclosure, j. the head of said bolt being of non-conventional shape whereby to be capable of rotation only by a special tool and thus nonremovable by unauthorized persons, k. the said support member against which said bolt head is engaged including a protective wall portion peripherally surrounding said bolt head and open at the outer end, l. said wall portion defining a socket which is at least as deep as the thickness of the bolt head to prevent side engagement of the bolt head by unauthorized persons and which is of greater diameter than said bolt head by unauthorized persons and which is of greater diameter than said bolt head to permit removal of the bolt by a special tool inserted through the open end of the protective wall portion.
