Collapsible, erectable canopy shelter with a crank system
A canopy erectable by a single user by use of a crank assembly. The canopy is constructed of an expandable frame including legs, vertical rotating members, and horizontal rotating members. Each leg has a foot on one end. One foot has a stepping portion and each of the remaining feet have a sliding portion. The vertical rotating members are each connected to one leg and are movably connected to each other vertical rotating member at a centerpoint. The horizontal rotating members are each rotatably connected between two different legs at a fixed point on each leg. Each leg also has a movable bracket slidably connected to it and the bracket is rotably connected to each adjacent horizontal rotating member. A crank is affixed to the leg with the first foot; wherein the crank is operably connected to control the position of the movable bracket.
1. A canopy comprising
an expandable frame comprising
a plurality of legs, each leg also having a foot on a distal end, wherein a first foot has a stepping portion and each of the remaining feet have a sliding portion;
a plurality of vertical extensible members, each connected to one leg opposite the foot and are movably connected to each other vertical extensible member at a center point;
a plurality of horizontal extensible members, each horizontal extensible member rotatably connected between two different legs at a fixed point on each leg;
a movable bracket slidably connected to each leg and rotatably connected to each adjacent horizontal extensible member; and
a crank assembly affixed to the leg with the first foot, wherein the crank is operably connected to control the position of one or more of the movable brackets.
