Abstract:
1. A pull-button, locking hinge assembly comprising, in combination: a) a base element comprising: a solid cast geometric first open end comprising an internal recess; a cylindrical length comprising an external side and an internal side; a central longitudinal axis; a cylindrical recess defined by the cylindrical length internal side; a second open end; a plurality of uniform cogs evenly spaced along the cylindrical length internal side from the second open end so that each cog length is disposed equidistant from and parallel to the central longitudinal axis, and the cogs are sized to fit and receive cogs along a pull-button cylindrical body external side; and an annular groove around the cylindrical length external side, the annular groove defining a plane transverse to the central longitudinal axis; b) a pull-button element comprising: a cylindrical body comprising an external side; a central longitudinal axis; an non-actuating end comprising a solid circular external surface; an actuating end comprising an arm; a plurality of cogs evenly spaced along the cylindrical body external side so that each cog length is disposed equidistant from and parallel to the cylindrical body central longitudinal axis; c) a cap element comprising: a solid cast geometric first open end comprising a central opening on the end sized to receive the pull button non-actuating end; a cylindrical length comprising an external side and an internal side; a central longitudinal axis; a cylindrical recess defined by the cylindrical length internal sides; a second open end sized to be press fitted about the base second open end to receive and hold the base second open end; a plurality of uniform cogs evenly spaced along the cylindrical length internal side from the cap element first open end comprising a central opening to receive the pull button non-actuating end so that each cog length is disposed equidistant from and parallel to the central longitudinal axis, and the cogs are sized to fit and receive the cogs along the pull-button cylindrical body external side; and an annular groove around the cap cylindrical length internal side, the annular groove defining a plane transverse to the base central longitudinal axis; d) an O-ring sized to be received within (i) the annular groove around the base cylindrical length external side, and (ii) the annular groove around the cap cylindrical length internal side, the O-ring serving to provide a pivot surface between the base element and the cap element; wherein the pull-button, locking hinge assembly provides a locking feature when the pull-button element actuating end arm is in a disengaged, neutral position and the pull-button element cogs simultaneously engage the base element cogs and the cap element cogs preventing any pivot between the base element and the cap element about the central longitudinal; axis; wherein the pull-button, locking hinge assembly provides a 360 degree pivot feature around the O-ring between the cap element and the base element, the pivot action being along a plane transverse to the central longitudinal axis and about the central longitudinal axis, when the pull-button actuating end arm is engaged and pulled outward from the base element solid cast geometric first open end disengaging the pull-button element cogs from the cap element cogs and unlocking the pull-button, locking hinge assembly; and wherein once the pull-button element actuating end external surface returns to a neutral position by the action of pressing the pull-button element actuating end arm inward from the base element solid cast geometric first open end, the pull-button element cogs re-engage the cap element cogs and lock the pull-button, locking hinge assembly into the adjusted pivoted position between the base element and the cap element about the central longitudinal axis.
