ABSTRACT:
A door latching arrangement is provided for an enclosure that stores energy at each position in a range of opening positions such that if the door is manipulated to permit opening, sufficient energy is available to permit the automatic latching of the door upon closing. The door latching arrangement includes a movable latch arm which in a specific arrangement is carried by the door. The latch arm is biased to engage a projection or hasp of the enclosure when the door is closed. A latch retaining member carried by the door is arranged to interact with the latch arm to prevent the engagement of the latch arm by the hasp. Movement of the latch arm to disengaged the hasp, coupled with the opening of the door to separate the hasp and the latch retaining member, results in the latch retaining member moving to a position to interact with and retain the latch arm. When the door is closed, the hasp conditions the latch retaining member out of interaction with the latch arm, permitting the latch arm to automatically re-engage the hasp. In a specific arrangement, the latch retaining member and the latch arm include a pawl and ratchet combination that is operative upon movement of the latch arm out of engagement with the hasp and as the door is opened to separate the hasp and the latch retaining member.
