  • Patent number: 4344253
    Abstract: A door edge and hinge guard in the form of a U-shaped member is secured to a door frame longitudinally thereof to protect the edge of an open door and its hinge therein by resiliently deflecting objects such as shopping carts and the like away from contact with the edge of the door and the hinge.

  • Patent number: 4338148
    Abstract: A method of manufacturing a door edge guard of the type particularly suitable for protection of the edge of an automobile door from paint chips. The method is an improvement over the technique of using separate manufacturing procedures to produce a plastic U-shaped inner channel (liner) configured to mate with a U-shaped metal outer channel. The method of the invention comprises the steps of roll-forming a metal element of an edge guard into a U-shaped channel element and bonding a plastic material to at least a portion of the inner surface area of the U-shaped metal element prior to completion of the roll-forming operation. The bonding may take place before roll-forming is begun.

  • Patent number: 4334700
    Abstract: An ornamental and protective vehicle door edge guard comprises a metallic strip of generally U-shaped cross section which is self-retaining on the door. Disposed on either, or both, free longitudinal edges of the metallic strip is a non-metallic strip of generally U-shaped cross section which serves to protect the door paint from being scratched or marred when the edge guard is applied to the door. The non-metallic strip further serves to insulate the metallic strip from the metal of the door.

  • Patent number: 4330022
    Abstract: The device consists of a pair of semicircular, transparent sheets of resilient plastic material, one of the sheets having molded on one surface a series of pegs which are insertable through the mesh of the screening. The other sheet has a corresponding pattern of holes to receive the pegs such that the two semicircular sheets can be secured together with a portion of screening between them in sandwich fashion. The device is used to reinforce and protect the mesh screening adjacent to the handle of a screen door so that bulging or accidental puncturing of the screening is avoided.

  • Patent number: 4316348
    Abstract: An ornamental and protective vehicle door edge guard comprises a metallic strip of generally U-shaped cross section which is self-retaining on the door. A non-metallic insulating strip of generally U-shaped cross section forms an insulating liner between the metallic strip and the door. The non-metallic strip is applied to the door edge by itself before the metallic strip and comprises a longitudinally conformable material which allows it to be readily conformed to the contour of the door edge. The free edges of the non-metallic strip seal between the free edges of the legs of the metallic strip and opposite sides of the door edge.

  • Patent number: 4271633
    Abstract: An ornamental and protective molding for the edges of vehicle doors in which a U-shaped metal strip is formed with beads acting as guides to facilitate installation of the molding on vehicle doors without scratching the painted surfaces with the beads acting as clamping surfaces for retaining the molding on the door. The outer leg of the strip has a single thickness of material and the inner leg a double thickness, and an insulating liner nests within the strip to insulate it from the door edge.

  • Patent number: 4259812
    Abstract: An ornamental and protective molding for the edges of vehicle doors in which a U-shaped metal strip is lined with a nonmetallic material so that the lining strip facilitates insulation of the molding and acts as an insulator and seal to prevent rusting and corrosion.

  • Patent number: 4242848
    Abstract: An edge protecting and reinforcing channel for shelves, boards, and similar plane platelike members. The channel is formed of a single metal strip and as seen in cross section includes an exterior section and two legs perpendicular thereto, and arranged such that with the exterior section extending along an edge of a board, the legs of the channel extend along adjacent portions of the two opposite side surfaces of the board. The free end portions of the legs are formed as inwardly bent edge flaps arranged to be introduced into grooves in the side surfaces of the board. Corner portions joining the exterior section to the legs are bent outwards and thereby form a free space at the inside of such corner portions to loosely cover the corners of the board. The bent flaps at the free edges of the legs of the channel form an acute angle relative to the channel legs.

  • Patent number: 4240225
    Abstract: An integral piece for applying to a sharp corner element such as on a window frame, having a base with a recess in its under surface with flanges or ribs on two contiguous sides. Rising from the base is a rounded boss, symmetrical on a diagonal line from the juncture of the flanges. When applied to the window frame, the flanges fit against the edges of the frame forming the sharp corner, and the boss extends both up from the base and generally toward the corner. The symmetry of the guard enables it to fit either corner of the window frame, i.e., either right or left. The guard is held in place alternatively by an adhesive material, or mechanical means such as a screw.
