A track system may include a track assembly and a support assembly. A track assembly may include a wheel receptacle. The support assembly may include a support member removable from and adjustably connected to the track assembly. The support member may include a wheel. The wheel may be adjustable to an engaged position in which the wheel engages the wheel receptacle. The wheel may be adjustable to a disengaged position in which the wheel is not engaged with the wheel receptacle.

A track system may include a track, a support assembly, and a flexible member. The support assembly may include a support member removably and adjustably connected to the track. The flexible member may be connected to the support member. The support member may include a pinion. The flexible member may be adjustable to a first flexible member position in which the pinion and the track are not engaged with one another. The flexible member may be adjustable to a second flexible member position in which the pinion and the track are engaged with one another.

A support member may be connectable in a removable and adjustable manner to a track assembly. The support member may include an electrical connector, a contact, and a biasing member. The electrical connector may be adjustable to a first position and a second position. The contact may be connected to the electrical connector and configured to engage a conductor of said track assembly. The contact may be engageable with said conductor when the electrical connector is in the first position. The contact may not be engageable with said conductor when the electrical connector is in the second position. The biasing member may be configured to bias the contact into engagement with said conductor when the electrical connector is in the first position.

A window shade system includes a first bracket coupled to a first pivot and rotatable at least within a first range of angles, a second bracket coupled to a second pivot and rotatable at least within a second range of angles, and first and second gears that each include a circular base rotatable about a central axis. Gear teeth are arranged in a same row and extend outward from the outer region and are evenly spaced from each other along the outer region of the gears. The first and second pivots are arranged relative to each other and relative to the central axes of the first and second gears, respectively, such that for any angle within the first range of angles, the gear tooth of the first gear meshes with the gear tooth of the second gear at a corresponding angle within the second range of angles.
