Ratcheted pipe and strap operating drive system for door mechanisms

A ratcheted pipe and strap operating drive system, utilized for positioning of a hinged door mechanism, which hinged door mechanism is immediately adjacent to a correspondingly-dimensioned opening integral to a structure, the ratcheted pipe and strap drive operating system enabling placement of the door mechanism at any point between fully closed upon the opening, or spaced apart from the opening, the system comprising:

• a straight pipe, at least two internally-ratcheted reel assemblies, at least two straps, at least two guide brackets having integral roller pins, at least two L-shaped braces, each having an integral drive shaft collar;
• and
• a plurality of fasteners;
• whereby
• each reel assembly further comprises a lock ring, a spring washer a collar spring, a pipe sleeve collar, a strap reel, said strap reel comprised of a left wall and a right wall, each wall being connected by a hollow core and further, having driven gear teeth on the right wall, a pipe sleeve, and a cylindrical lock gear having driving gear teeth corresponding to the driven gear teeth of the strap reel;
• each of the at least two reel assemblies is rotatingly and symmetrically affixed onto the outer surface of the straight pipe;
• the straight pipe is supported, at each end, within a drive shaft collar of the respective L-shaped brace, the braces further being permanently affixed to the structure proximate the opening of the structure cavity and oriented coaxially to the pipe;
• each of the at least two guide brackets is affixed to the structure, proximate each strap reel and in alignment with, the core of each respective reel assembly;
• each of the straps is attached at the first end of the strap to the core of one of the respective reel assemblies, the free length of each strap being routed between the guide bracket and the roller pin of the guide bracket, and the second end of the strap attached to the exterior surface of the door mechanism;
• whereby
• rotation of the pipe about its linear axis in one direction causes the reel assemblies to simultaneously rotate, thereby causing each of the at least two straps to move the hinged door in a first direction, relative to the opening of the structure and conversely, rotation of the pipe in the opposite direction, causes each reel assembly to rotate and move the hinged mechanism opposite of the first direction.
