To raise the cane bolt, the cane bolt is simply rotated so that the pin aligns with and thus passes through the slot, allowing the spring to urge the cane bolt up.

Abstract: A keyless door lock that prevents young children from opening doors. The lock is a bolting mechanism type lock or a latching type lock having no keyed lock access side to it, but rather, a means for locking and unlocking the lock, such as a knob, on one or both sides of the door that when turned, unlocks the door. The lock is positioned within the door at a height that is unreachable by small children. The lock can lock doors internal to the home (e.g., doors to medicine closets, cleaning supply closets, garage doors, doors at the top of stairs) and doors that provide access to the exterior of the home, thus access to leave the home without supervision. Adults and older children, however, are never locked in or out of the room or house as merely the turning of a knob is required for operating the lock.

Abstract: A latch has a bushing which has at least one bushing projection or means for preventing insertion of an unauthorized tool to rotate a latch actuator of the latch. Only a key having an outer key recess which can mate with bushing projection on the bushing permits insertion of the key. The cap subassembly of the latch is provided with projections which are of a size and so positioned as to correspond with the internal recesses of the key so as to allow the cap subassembly to enter into the bore of the key and permit a mating engagement of internal recesses on the key and projections on the cap subassembly. Because cap portion rotates freely on top of the cap subassembly which is the part of the cap driven by the key, the arrangement makes it impossible, or at least very difficult, to rotate the shaft and in turn the pawl by means of a tool which rotates the cap portion.

Abstract: A hatch securing mechanisms has a base attached to a hatchway and a hasp ached to a hatch lid. The base has an apertured retainer and a pinway element, the hasp being held between the retainer and pinway element during closure of the lid. A latch pin translatable in the pinway element has an angled tip which slides against a bevelled surface of the hasp to force the hasp into tighter, locked engagement with the base. The latch pin has a helical groove segment about the pin's axis, and a stud fixed to the pinway element engages the groove segment. The interaction of the stud and groove segment effects translation of the latch pin when the pin is manually rotated. The action of the latch pin also compresses an elastically deformable seal between the door and door frame so that the seal is increasingly effective against explosive blast pressures. The invention includes a lock mechanism for keeping the latch pin in a hasp retaining position unless the pin is manually moved.
