A kit of reusable paint masks for door hinges for use when painting a door and frame comprising two masks, one mask for protecting the door hinge butt plates and the other mask for protecting the pin cylinders. The door hinge butt plate mask is made of a flaccid material having spaced flexible magnetic elements for attachment to magnetically attractable door hinge butt plates by magnetic force. The magnetic elements enable the mask to be readily adjusted for proper registration without requiring removal and reapplication of the mask. A tab is also provided for removal of the mask after completion of the painting. The pin cylinder mask is made of a resilient material of U-shaped transverse cross section with the sides and back engaging the pin cylinder to cover it. Both masks can be manufactured in a variety of standard and specialty sizes.
For use in painting a door supported from a frame by door hinges which comprise magnetically attractive butt plates and hinge pin cylinders, a reusable mask to provide protection against paint being placed on said butt plates and hinge pin cylinders, said mask comprising a sheet having first and second outer external regions each of size and shape which approximates the size and shape of each of said butt plates, said sheet comprising a flaccid intermediate region between said external regions, said intermediate region being of a size and shape so as to be coextensive with the hinge pin cylinder when applied to said hinge, magnetic means extending only over said outer external regions of said sheet for attaching said sheet only to the hinge butt plates by magnetic attraction forces, and means for securing said magnetic means to said outer external regions of said sheet, said magnetic means and said securing means comprising means for attaching said mask to said hinge without restricting angular movement of the door to which said mask is attached.
The reusable paint mask of claim wherein the magnetic bodies are substantially rectangular in shape.
A reusable pin cylinder mask to provide protection against paint being placed on the hinge pin cylinders, said mask being of resilient material and being elongated and of U-shaped transverse cross section, said pin cylinder mask having a back, the length of said back approximating the length of s id pin cylinder and the width of said back approximating the outer diameter of the hinged pin cylinder, said pin cylinder mask having two sides each formed at an acute angle to the back and converging from said back toward each other to engage and cover the hinge pin cylinder, the length of said sides approximating the length of said back and the width of said sides approximating the outer diameter of said hinge pin cylinder, and a top of said pin cylinder mask substantially perpendicular to said back and whose length corresponds to the width of said sides and whose width corresponds to the width of said back.
