Abstract: A draft blocking apparatus for a door is described. A hinge for attachment to a door is described. A rotating assembly attached to the door permits the rotating assembly to rotate about the hinges, and to rotate relative to the door, the rotating assembly arranged to accommodate a draft blocker. A mechanism to convert motion of the door as the door is closed into motion to lower the draft blocker into a position to contact a floor by rotation about the hinges, in order to block a draft which would otherwise pass under the door when the door is in a closed position.

Abstract: A system for mounting, storing, and quickly changing displays is provided. The use of pins which pass through mounting holes in either the margin of items to be displayed or through mounting holes in tabs attached to an item to be displayed is provided. The pins then anchor into holes in support materials which may be for example, a backing board, for example, a mat board, or for example, an easel. The dynamics of the mounting may be achieved by way of pins attached to the support material.The system also provides for storage of additional items, which are held in place in storage by way of the same system of pins, shanks, mounting holes and anchoring holes and fixed pins.

Abstract: A display system for items, the system featuring easy substitution of a second group of items for a first group of items is provided. A display assembly has a frame, a mat, a retainer for the items, and a backing board. Pins inserted through holes anchor the retainer to either the backing board or the mat. The transparent plate may be made of ultra-violet light absorbing material in order to protect the desired materials from ultraviolet radiation striking the transparent plate. The pins may be formed as part of a pin strip, the pin strip formed by plastic molding, and the pins inserted into holes in the backing board. The pins may be wood dowels or may be aluminum rods. The aluminum rods may have a flat head formed thereon.

Abstract: A display system for a plurality of small items, the system featuring easy substitution of a second group of items for a first group of items, and featuring protection of the items from ultra-violet radiation. A transparent plate is mounted within a frame, the transparent plate transparent to light in the visible wavelength range and absorbent in the ultra-violet wavelength range to protect the items from ultra-violet wavelength radiation; a mat is mounted within the frame, as is a retainer to hold the items. A backing board forms a back support in the frame to hold the transparent plate, the items, the mat, and the retainer. The retainer may be a sheet of transparent material having holes formed therein. Pins inserted through the holes anchor the retainer to either the backing board or the mat.
