摘要： A self-closing, sliding door assembly in which a latch arm is pivotally mounted for selective movement into engagement with a counterweight that is connected to a sliding door movable between open and closed limits, the counterweight tending to move the door to the closed limit and the latch arm selectively holding the door in the open limit. The latch arm is weighted to move automatically out of engagement with the counterweight as the counterweight load is removed from the latch arm as the door is moved a further distance in the direction of the open limit, thereby releasing the counterweight to move the door toward the closed limit. More particularly, the latch arm has one end selectively movable under the counterweight while a stop limits rotation of the latch arm so that the latch arm can support the counterweight. The other end of the latch arm is weighted relative to the one end engageable with the counterweight so that the latch arm will pivot automatically under gravity to a position in which the one end is disengaged from the counterweight when the counterweight load is removed from the arm.
