  • Patent number: 5799443
    Abstract: A temporarily installed resilient, shock-absorbent cover to protect the vulnerable parts of doors and door frames, as well as the frames of archways and the furniture that passes therethrough during the process of moving is disclosed. The cover includes a hinge side frame cover temporarily secured to the door. The hinge side frame cover shields the face of the door frame, and also shields a portion of the door. A latch side frame cover protects the latch side portion of the door frame. The latch side frame cover has an angular U shape which covers the forward, inner and rear face of the door frame. The cover is held in place by upper and lower retainer clips which are permanently attached thereto. The clips apply pressure to the wall creating friction to hold the cover in position. In archways where no door is present, both sides of the opening are covered with latch side frame covers.
