Abstract: A support system is provided for mounting on a wall at an opening for a window or glass door. The support system is designed to support horizontal blinds or shades with the brackets that are ordinarily used to mount the blinds directly to a wall. The support system has control mechanism to move the blind or blinds laterally away from the window or door to allow access to the window or door. This is easier than raising the blind high enough to allow access. The support slides laterally behind another shade. In another embodiment the support is hinged in the middle and folds together like a bi-fold door to open.
