Attachment apparatus, system and method

摘要

Provided is an adjustable attachment apparatus, system and method, including in various example embodiments a block adapted to rotatably engage a ball portion of an arm, where the arm may be connected with a base that connects with a helical rotatable member. In various example embodiments the ball portion of the arm may “pop” in and out of the block when compressing fasteners in the block are loosened, and the ball portion of the arm may be locked in place by tightening the compressing fasteners, to position the arm and attached structures in any of a variety of positions. In various example embodiments the block may be rotatably mounted to a surface, and the base may be rotatably mounted to the arm, and the helical rotatable member may be pivotally mounted to the base. A plurality of arms may be connected together using one or more double-ended blocks.

主权项

1. An adjustable attachment apparatus comprising:
a cylindrical block having a longitudinal axis; and an arm having a ball portion defining a convex portion of a sphere; wherein the cylindrical block comprises a bottom portion with two cantilevered sides extending distally from the bottom portion and defining a slot there between, the two cantilevered sides each defining in a distal portion thereof a concave portion adapted to rotatably and lockably engage the ball portion of the arm, and two fasteners each engaging and urging together the two cantilevered sides, the two fasteners located in a plane perpendicular to the longitudinal axis of the block and at least substantially recessed within the cylindrical block; wherein when the two fasteners are loosened the ball portion of the arm can be popped into place in between the two cantilevered sides and rotatably engaged by the concave portions of the two cantilevered sides; and wherein the concave portions of the two cantilevered sides are configured to lockably engage the ball portion of the arm when the two fasteners are tightened.
