Abstract

A door that has a beam and door panel that are secured by molding the door panel to the beam.

Claims (36)

1. An access door, comprising:

a door panel having an outer edge;

a beam attached to said outer edge of the door panel;

an oscillator located entirely within the beam and secured to the beam, said oscillator engages a support pin that is at least partially located in said beam to support the beam; and

a coating on the door panel and on the beam, said coating assists in securing the beam to the door panel.

2. The access door of claim 1 , where the door panel is a frame that is strengthened by the coating.

3. The access door of claim 1 , where the door panel is a solid core door panel.

4. The access door of claim 1 core is made of insulating material.

5. The access door of claim 1 , where the coating is a polymer.

6. The access door of claim 5 , where the polymer is an elastomeric polyurethane.

7. The access door of claim 1 , where the beam is attached to only a portion of the door panel.

8. An access door, comprising:

a door panel having an outer edge;

a beam attached to said outer edge of the door panel;

a pin secured in the beam that has at least one wheel that engages an oscillator, said oscillator is located entirely within the beam and said oscillator is secured to the beam; and

a coating on the door panel and on the beam that assists in securing the beam to the door panel.

9. The access door of claim 8 , where the door panel is a frame that is strengthened by the coating.

10. The access door of claim 8 , where the door panel is a solid core door panel.

11. The access door of claim 8 where the core is made of insulating material.

12. The access door of claim 8 , where the coating is a polymer.

13. The access door of claim 12 , where the polymer is an elastomeric polyurethane.

14. The access door of claim 8 , where the beam is attached to only a portion of the door panel.

15. A method for creating the access door of claim 1 , comprising the steps of:

forming a core with edges and a top panel and a bottom panel;

coupling a beam to the core;

molding the core and beam together with a least at least one coat of a polymer.

16. The method of claim 15 , where molding further includes the step of spraying the polymer on the core and beam such that the core is secured to the beam by the polymer.

17. The method of claim 16 , where spraying further includes the steps of:

spraying the edges of the core; and

spraying the top panel and the bottom panel of the core after the edges of the core have been sprayed.

18. The method of claim 15 , where the core is made of insulating material.

19. The method of claim 15 , where the polymer is an elastomeric polyurethane.

20. The method of claim 15 , further includes the steps of:

placing a window in the core; and

overspraying the window with the polymer in order to secure the window in the core.

21. The method of claim 15 , where the thickness of the polymer is between ⅛″ and ½″ inclusive.
