Abstract
A high speed door assembly, comprising an actuator cylinder and piston rods, a pressure supply cylinder and fittings, an electrically detonated explosive bolt, a honeycomb structured door, a honeycomb structured decelerator, and a structural steel frame encasing the assembly to close over a 3 foot diameter opening within 50 milliseconds of actuation, to contain hazardous materials and vapors within a test fixture.
Claims20
A high speed door assembly for fast closure of an opening comprising:
- a frame, said frame including two vertical channel members each having an upper and lower end, an upper horizontal channel member, and a lower horizontal channel member with one end of each of said upper and lower horizontal channel members connected to and traversing said vertical channel members at each of said upper and lower ends forming a continuing channel around the inner periphery of said high speed door, and said upper traversing horizontal channel member having an orifice located midway between said two vertical channel members;
- a pressure supply cylinder connected to said frame;
- an actuator cylinder encased in said pressure supply cylinder, said actuator cylinder having a piston encased therein including an upper and lower piston rod extending axially therefrom and said upper piston rod passing through said orifice of said upper traversing horizontal channel member;
- a honeycomb door element having a top and bottom surface area depose din said frame, said top surface area attached to said lower piston rod, and said honeycomb door element being held in a open position over said opening;
- means for deceleration affixed to said lower traversing horizontal channel member, wherein when said honeycomb door element is released said means for deceleration is positioned in such a way that the bottom surface of said honeycomb door element impacts said means for deceleration at a closed position thereby preventing movement of said honeycomb door element beyond a predetermined distance across said opening;
- and
- means for actuation connected to said upper piston rod and affixed to said upper traversing horizontal channel member.
A high speed door assembly as recited in claim wherein said pressure supply cylinder further comprises:
- a spider connected to said pressure supply cylinder and positioned above said actuator cylinder, and said pressure supply cylinder having means for maintaining an internal pressure of at least 800 psi.
A device for quick closure and containment of an opening comprising:
- a frame and said frame is positioned across said opening;
- a pressure supply cylinder connected to said frame;
- an actuation cylinder encased in said pressure supply cylinder;
- a honeycomb door slidably deposed in said frame;
- means for deceleration connected to said frame;
- and
- means for actuation connected to said frame, whereby when said means for activation is engaged said honeycomb door is thrust across said opening providing a quick closure.
