Intumescent material in a continuous pinless hinge

A heat resisting assembly for continuous pinless hinges comprising:

• a bearing cap assembly having a back wall which has an outer side and an inner side, two side walls extending from the opposite ends of the back wall, an intumescent material recess located on the inner side of the back wall which extends essentially the entire length of the inner side, and two intumescent material retention lips, one of which extends inwardly from each of the side walls;
• an intumescent material of the type which expands when heat is applied to it, filling in crevices and retaining resiliency once it hardens;
• means for securing the bearing cap and intumescent material;
• interlocking pivot gears containing at least one bearing;
• and,
• the intumescent material being placed in the intumescent material recess and supported by the intumescent material retention lips of the bearing cap assembly, the bearing cap assembly then being displaced over the interlocking pivot gears and bearings, and being secured into place by the securing means.

A method for making a continuous pinless hinge containing intumescent material comprising the steps of:

• creating a continuous pinless hinge having a door leaf, a frame leaf, an interlocking pivot gear, at least two bearings found at pre-determined locations along the length of the pivot gear, intumescent material, and a bearing cap assembly having means for accepting intumescent material, and at least two set screws;
• placing a strip of the intumescent material into the bearing cap means for accepting intumescent material;
• disposing the bearing cap assembly containing intumescent material over the pivot gears and bearings;
• and,
• securing the bearing cap assembly containing intumescent material to selected bearings with at least two set screws which are placed through strategically placed predrilled bearings, pierce intumescent material and affixed to the bearing cap assembly.
