Abstract: In some embodiments, a canopy structure includes a plurality of support members, each including a first leg and a second leg telescopically slideable within the first leg to infinitely adjust a height of the canopy structure. The canopy structure can include a plurality of eaves including scissor-jack members moveable between an extended position and a collapsed position. The canopy structure can include a plurality of locking members. The locking members can be coupled to the first legs. The locking members can be adjustable between a locked and an unlocked position. The locking members can be configured to apply a radial inward force received by an area of the second legs when the locking members are in the locked position.
