Dual swivel in-line load node lock mechanism
View Patent ↗An in-line node locking mechanism for supporting and locking a node within a rack system such forces applied on a node by the node locking mechanism generate consistent output forces. The in-line node locking mechanism utilizes dual swivel nuts and an in-line loading arrangement that evenly distributes forces along the length of a rail system to create evenly distributed forces and avoid the creation of stress points. An actuating screw causes the node locking mechanism to adjust between unlocked and locked positions. In the unlocked position, the mechanism causes the node to be lowered and move freely along the in-line rail system. In the locked position the mechanism causes the node to securely abut the rack system thereby locking the node within the rack system.
1. A method, comprising:
providing an outer extrusion rail having swivel nut holes proximate one end and at least two sets of dowel pin holes spaced longitudinally along the outer extrusion rail;
providing an inner extrusion rail having swivel nut holes proximate one end and at least two sets of ramps spaced longitudinally along the inner extrusion rail, wherein said sets of ramps are spaced substantially the same distance apart as said sets of dowel pin holes;
disposing a bushing in each of said ramps;
attaching said bushings to said outer extrusion rail by placing a dowel pin through each of said bushings and through each of said sets of dowel pin holes;
disposing a through swivel nut in said swivel nut holes on said outer extrusion rail;
disposing a threaded swivel nut in said swivel nut holes on said inner extrusion rail;
placing a threaded actuating screw through said through swivel nut;
engaging said threaded actuating screw with said threaded swivel nut, wherein adjusting the threaded actuating screw changes the position of said inner extrusion rail with respect to said outer extrusion rail.
