Height-adjustable canopy leg

Abstract

In some embodiments, a canopy structure comprises a plurality of support members, each comprising 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 comprise a plurality of eaves comprising scissor-jack members moveable between an extended position and a collapsed position. The canopy structure can comprise 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.

What is claimed is: 
     
         1 . A canopy structure comprising:
 at least one support member, the support member comprising a first leg and a second leg, the second leg telescopically slideable within the first leg to adjust a height of the canopy structure;   an upper frame comprising at least one eave coupled to an upper end of the support member, the eave comprising at least one scissor-jack member moveable between an extended position and a collapsed position; and   a lock coupled to the first leg, wherein the lock is adjustable between a locked and an unlocked position, wherein the lock is configured to apply a retaining force to an outer surface of the second leg when the lock is in the locked position to secure the first and second legs in a desired position relative to one another.   
     
     
         2 . The canopy structure of  claim 1 , wherein the lock is configured to apply a sufficient radially-inward retaining force to support the canopy structure at a fixed height. 
     
     
         3 . The canopy structure of  claim 1 , wherein the area of the second leg receiving the retaining force is distributed about a substantial entirety of a perimeter of the second leg. 
     
     
         4 . The canopy structure of  claim 1 , wherein the lock comprises a body having a portion that surrounds the second leg and the retaining force is created by reducing a perimeter of the portion of the body. 
     
     
         5 . The canopy structure of  claim 1 , wherein the lock is configured to secure the first leg and second leg at any position within a range of available heights. 
     
     
         6 . A canopy structure comprising:
 at least one support member, the support member comprising a first leg and a second leg, the first leg and the second leg telescopically engaged with one another for movement along an adjustment axis to permit adjustment of a height of the support member;   an upper frame comprising at least one eave coupled to an upper end of the support member, the eave comprising at least one scissor-jack member and at least one sliding eave mount moveable along the adjustment axis between an extended position and a collapsed position;   a canopy cover supported by the upper frame; and   a lock movable between a locked position and an unlocked position, wherein a portion of the lock is configured to apply a retaining force to a surface of one of the first leg and the second leg when the lock is in the locked position to retain the first leg and the second leg in a fixed position relative to one another or to retain the sliding eave mount in a fixed position relative to one of the first leg and the second leg, wherein the retaining force is applied to the surface in a direction substantially perpendicular to the adjustment axis.   
     
     
         7 . The canopy structure of  claim 6 , wherein the lock is actuated by a lever. 
     
     
         8 . The canopy structure of  claim 7 , wherein the lock comprises a body that surrounds the support member. 
     
     
         9 . The canopy structure of  claim 8 , wherein a perimeter of a portion of the body is reduced in the locked position to apply the retaining force to the one of the first leg and the second leg. 
     
     
         10 . A canopy structure comprising:
 at least one support member, the support member comprising a first leg and a second leg, the second leg telescopically slideable within the first leg to adjust a height of the canopy structure;   an upper frame comprising at least one eave coupled to an upper end of the support member, the eave comprising at least one scissor-jack member moveable between an extended position and a collapsed position; and   a lock coupled to the first leg, wherein the lock is adjustable between a locked and an unlocked position, wherein the lock comprises a lock body having a first portion surrounding the first leg and a second portion surrounding the second leg, wherein the lock is configured to apply a retaining force to an outer surface of the second leg when the lock is in the locked position to secure the first and second legs in a desired position relative to one another.   
     
     
         11 . The canopy structure of  claim 10 , wherein the lock is actuated by a lever.
