Coupler system

A drape-and-rod coupler system for connecting elongate, horizontally disposed poles to vertical supports, comprising:

• a top-cap component for attaching to the top of one of the vertical supports, including a body with plural sidewalls and plural cavities, and wherein each cavity is formed by adjacent sidewalls with each cavity having an integral top region that is open, an integral bottom region, and with an elongate channel that terminates above the bottom region and has a width;
• at least one ball-cap curved-surface component for attaching to an end of one of the poles, and including a spherically-shaped ball curved-surface attachment region coupled to a rigid cylindrical neck so that rotation of the ball curved-surface attachment region results in angular movement of the neck, with the ball curved-surface attachment region having a diameter dimension larger than the neck that exceeds the width of the channel but also allows the ball to fit within one of the plural cavities of the top-cap component and retains the curved-surface attachment region within the cavity;
• wherein the at least one ball-cap curved-surface component and the top-cap component are constructed to allow the ball-cap curved-surface component to be received into a corresponding cavity, via the open, top region of the cavity, and to be held in the cavity by the combination of the ball diameter dimension of the curved-surface attachment region larger than the neck, the channel, width and the integral bottom region;
• and
• wherein the top-cap and curved-surface components are constructed from material that is designed to have memory so that the ball curved-surface attachment region returns to the original position after an application of force is removed.
