Definitions

  • the present invention relates to masking devices, and more particularly to a tubular masking device for masking cylindrical members.
  • the painting or coating of parts may involve liquid coating, plating, powder coating or electroplating.
  • the coating may be applied by a variety of methods including brushing, rolling, spraying, dipping, plating, flow-coating, electro- static coating, and submersion in deposition tanks.
  • the liquid, powder or plating material may be applied to wood, fiberglass, or metal surfaces in order to protect and/or strengthen those surfaces.
  • the coating protects the surface of apart by preventing electrical leakage, oxidation, corrosion and decay.
  • Once the coating is applied it is often cured at temperatures between 200-600° Fahrenheit to harden and cross-link the coating on the surface. After the curing process is complete, the cured coating forms a very strong protective layer on the surface that is highly resistant to scratching and chipping.
  • a protective coating is applied to certain areas of a surface but not to other areas of the surface.
  • the areas where the coating is not to be applied must be covered or masked off by a masking device.
  • a masking device is applied to the surface areas to be masked. Once the painting or coating process is complete, the masking device is removed from the surface of the part.
  • cylindrical members such as rods, pipes, or axles need to be masked when the ends of the cylindrical members are painted or coated.
  • the shape of the cylindrical members make them very difficult to mask especially if there are end members attached to the ends of the cylindrical member which are difficult to remove and/or larger than the cylindrical member itself.
  • the present invention provides a tubular-shaped masking device for masking cylindrical members during liquid coating, powder coating, plating or electroplating.
  • the masking device is preferably made from a flexible high temperature resistant plastic or rubber material, such as neoprene or ethylene-propylene-diene terpolymers (EPDM) for easy attachment and removal from the cylindrical members.
  • EPDM ethylene-propylene-diene terpolymers
  • the masking device comprises a tubular-shaped substrate having a top surface and a bottom surface.
  • the substrate includes a first end and a second end, the first end being coiled inside of the second end to form the tubular-shaped masking device.
  • the masking device is placed over the top surface of a cylindrical member by opening and separating the first and second ends of the tubular shaped masking device so that there is an opening large enough to place the masking device over the top surface of the cylindrical member.
  • the masking device is preferably made of a resilient material such that when the masking device is placed over the top surface of a cylindrical member, the first and second ends return to their original shape and position to totally enclose the outside surface area of the cylindrical member.
  • the masking device is easily attached over cylindrical members having end members attached to the ends of the cylindrical member which are difficult to remove and/or larger than the outer surface of the cylindrical member to be masked.
  • the bottom surface of the masking device comes into contact with the outer surface of the cylindrical member.
  • the masking device is removed from the cylindrical member. This is accomplished by separating and opening the first and second end members of the tubular-shaped masking device to form an opening large enough to remove the masking device from the cylindrical member.

Abstract

L'invention porte sur un dispositif (10) de masquage tubulaire destiné à masquer des éléments cylindriques. Ce dispositif de masquage comprend un substrat doté d'une surface supérieure (16) et d'une surface inférieure (18). La surface inférieure est enroulée autour de la surface externe d'un élément cylindrique devant être masqué. Le dispositif de masquage comprend également une première extrémité (12) enroulée à l'intérieur d'une seconde extrémité (14). Ce dispositif (10) est de préférence utilisé pour masquer des éléments cylindriques possédant des éléments terminaux qui sont difficiles à retirer ou plus grands que l'élément cylindrique lui-même. On place le dispositif de masquage tubulaire sur la surface externe d'un élément cylindrique à masquer en ouvrant et en séparant les première et seconde extrémités du dispositif de masquage de façon à créer une ouverture suffisamment grande pour l'adapter autour de la surface externe de l'élément cylindrique.
