Abstract
Key threaded articles and systems that include key threads having a female lock and male key on a two-dimensional plane and in which the female lock envelops the male key when fully engaged and has a shape that creates lateral resistance to separation from the male key when the female lock fully engages the male key.
Claims29
A key threaded system comprising:
- a first part having a body comprising at least one mating surface upon which at least one key thread is disposed, said key thread comprising a key train comprising a plurality of key profiles forming an outer surface and having a key train length defined between a smallest key profile and a largest key profile;
- and
- a second part having a body comprising at least one mating surface into which at least one key lock is disposed, said key lock comprising a plurality of key lock profiles forming an inner surface having a lock length defined between a smallest lock profile and a largest lock profile;
- wherein said outer surface of said key train of said key thread and said inner surface of said key lock are each shaped and dimensioned to form a key thread set that follows a same key rail around an axis of rotation;
- wherein said outer surface of said key train of said key thread and said inner surface of said key lock are each shaped and dimensioned such that each key profile has a cross section that is progressively larger than an adjacent key profile along said key length from said smallest key profile to said largest key profile and each lock profile has a cross section that is progressively larger than an adjacent lock profile along said lock length from said smallest lock profile to said largest lock profile such that said key train may be moved through said key lock along said key rail without substantial interference until said smallest key profile reaches a tenninus position at said smallest lock profile;
- wherein said key train of said key thread and said key lock are each shaped and dimensioned such that each key profile has substantially the same shape and size as each lock profile at each point along the key rail when said smallest key profile reaches a terminus position at said smallest lock profile such that high surface contact is achieved between said outer surface of said key train of said key thread and said inner surface of said key lock of said first part and said second part when said smallest key profile reaches a terminus position at said smallest lock profile;
- and
- wherein said outer surface of said key train of said key thread and said inner surface of said key lock are each shaped and dimensioned to comprise a hook that resists lateral mechanical forces applied to said first part in a direction perpendicular to said mating surface of said second part.

The key threaded system as claimed in claim 22:
- wherein said at least one mating surface of said body of said first key disk comprise a substantially planar top mating surface and as substantially planar bottom mating surface;
- wherein said key thread is disposed upon said bottom mating surface of said first key disk;
- and
- wherein four key locks are disposed into the top mating surface of said body of said first key disk;
- and
- wherein said inner surface of each of said four key locks disposed into said top mating surface are shaped and dimensioned to follow a same key rail around an axis of rotation and such that said key thread disposed upon said bottom surface of said first part mate with four key locks the top surface of four first key disks to form a single key thread set.
