摘要： An apparatus for preventing a motor rolling door from falling includes a wedge shaped sliding plate located at one side of a driven sprocket, which is biased away from the driven sprocket by means of two actuating rods forced by two springs. Two rollers at the outer ends of two actuating rods push against the inner surfaces of the upper and lower stringers of the drive chain to keep the sliding plate away from the driven sprocket. When the drive chain is broken, the two actuating rods extend outward due to the action of the springs, and bias the wedge sliding plate toward the driven sprocket to engage with the driven sprocket, so that the rolling door is prevented from falling by its own weight.

摘要： A door assembly for pivotally securing a door to an animal enclosure or other enclosure. The door assembly comprises a pivot pin assembly integrally formed with the door and a hinge secured to the enclosure adjacent the opening. The pivot pin assembly preferably comprises a vertically oriented pivot pin integrally formed with upper and lower horizontal support members extending from upper and lower ends of the pivot pin across a portion of the door. The pivot pin is fitted within a hinge barrel formed within the hinge in a manner to permit the pivot pin to rotate within the barrel such that the door may be pivoted from an open to a closed position.
