In one embodiment a coupling for mounting a structure to an object is provided. The coupling comprises a pair of flanges releasably attachable to one another with planar surfaces thereof disposable in abutting relation. A plurality of linear slots is defined through one of the pair of flanges, and a plurality of arcuate slots is defined through the other of the pair of flanges. The linear and arcuate slots are arranged, shaped and dimensioned such that the flanges are alignable to overlap the linear and arcuate slots to define a plurality of through-bores for receiving fasteners, and such that they define a range of translational motion within which the flanges can be translated relative to one another and a range of rotational motion within which the flanges can be rotated relative to one another. At least one of the plurality of through-bores is maintained throughout the translational and rotational ranges. |
