SUPPORT MEMBER COUPLING METHODS AND APPARATUS

摘要

Embodiments of the inventive technology may be coupler apparatus such as pivot couplers (18) at may couple a non-horizontal item support rail to a rail (20) to a rail support leg (21) and that may enable rotatable motion of a coupled rail about a substantially vertical axis (13); rail may be coupled at an angle other than ninety degrees. Couplers may include compression elements (28) that may establish a cable channel adapted to direct one or more cables in a desired manner, such as to within the interior of a coupled rail at n end of that rail. The coupler apparatus may have an application in support stands such as musical instrument (e.g., drum) support apparatus.
