Rotating Shelf Adjustment Collar

Abstract

A display fixture includes a central pillar and a merchandise rack disposed along the central pillar and configured to support merchandise. A support member axially supports the merchandise rack along the central pillar. The support member includes a quick-release mechanism. The quick-release mechanism is adjustable between an engaged state, where the support member is not movable along the central pillar to secure a position of the support member and the merchandise rack along the central pillar, and a disengaged state, where the support member is movable along the central pillar for adjusting the position of the support member and the merchandise rack along the central pillar.

         6 . The display fixture of  claim 2 , wherein:
 with the quick-release mechanism adjusted to the engaged state, the axial passage of the clamp plate is not axially aligned with the central pillar and the inner cylindrical surface at least partially engages the central pillar to secure the position of the support member and the merchandise rack along the central pillar; and   with the quick-release mechanism adjusted to the disengaged state, the axial passage of the clamp plate is moved toward axial alignment with the central pillar and the inner cylindrical surface is moved away from engagement with the central pillar for adjusting the position of the support member and the merchandise rack along the central pillar.   
     
     
         7 . The display fixture of  claim 6 , wherein, with the clamp plate adjusted to the engaged state, the axial passage of the clamp plate is angled relative to a longitudinal axis of the central pillar. 
     
     
         8 . The display fixture of  claim 6 , wherein the clamp plate comprises:
 a first clamp plate comprising a first inner cylindrical surface defining a first axial passage of the first clamp plate; and   a second clamp plate comprising a second inner cylindrical surface defining a second axial passage of the second clamp plate.   
     
     
         9 . The display fixture of  claim 8 , wherein:
 with the quick-release mechanism adjusted to the engaged state, the first axial passage of the first clamp plate is not axially aligned with the second axial passage of the second clamp plate; and   with the quick-release mechanism adjusted to the disengaged state, the first axial passage of the first clamp plate and the second axial passage of the second clamp plate are moved toward axial alignment with one another and with the central pillar.   
     
     
         10 . The display fixture of  claim 6 , wherein:
 the biasing member urges a first end portion of the clamp plate axially along the central pillar to bias the quick-release mechanism toward the engaged state; and   with the quick-release mechanism adjusted to the engaged state, a second end portion of the clamp plate opposite the first end portion is movable along the central pillar to adjust the quick-release mechanism toward the disengaged state.   
     
     
         11 . The display fixture of  claim 10 , wherein the second end portion of the clamp plate comprises a grasping portion that is graspable by a user exterior the collar for manually adjusting the quick-release mechanism between the engaged state and the disengaged state. 
     
     
         12 . An adjustable support for a display fixture, the adjustable support comprising:
 a collar defining an axial passageway;   a quick-release mechanism accommodated by the collar, the quick-release mechanism comprising a clamp plate and a biasing member, the clamp plate comprising an inner cylindrical surface defining an axial passage of the clamp plate; and   wherein, with the adjustable support disposed along a central pillar of the display fixture, the central pillar extends through the axial passageway of the collar and the axial passage of the clamp plate, and the clamp plate is adjustable between:
 an engaged state, where the axial passage of the clamp plate is not axially aligned with the central pillar and the inner cylindrical surface at least partially engages the central pillar to secure a position of the adjustable support along the central pillar, and 
 a disengaged state, where the axial passage of the clamp plate is moved toward axial alignment with the central pillar and the inner cylindrical surface is moved away from engagement with the central pillar for adjusting the position of the adjustable support along the central pillar, the biasing member biasing the clamp plate toward the engaged state. 
   
     
     
         13 . The adjustable support of  claim 12 , wherein, with the adjustable support disposed along the central pillar of the display fixture, the adjustable support axially supports a merchandise rack of the display fixture along the central pillar. 
     
     
         14 . The adjustable support of  claim 13 , wherein the collar comprises a bearing surface, the merchandise rack pivotable about the central pillar and along the bearing surface. 
     
     
         15 . The adjustable support of  claim 14 , wherein the bearing surface extends from an upper surface of the collar. 
     
     
         16 . The adjustable support of  claim 14 , wherein the bearing surface is partially recessed into an upper surface of the collar. 
     
     
         17 . The adjustable support of  claim 12 , wherein, with the clamp plate adjusted to the engaged state, the axial passage of the clamp plate is angled relative to a longitudinal axis of the central pillar.

 a first clamp plate comprising a first inner cylindrical surface defining a first axial passage of the first clamp plate; and   a second clamp plate comprising a second inner cylindrical surface defining a second axial passage of the second clamp plate.   
     
     
         19 . The adjustable support of  claim 18 , wherein:
 with the clamp plate adjusted to the engaged state, the first axial passage of the first clamp plate is not axially aligned with the second axial passage of the second clamp plate, and   with the clamp plate adjusted to the disengaged state, the first axial passage of the first clamp plate and the second axial passage of the second clamp plate are moved toward axial alignment with one another and with the central pillar.   
     
     
         20 . The adjustable support of  claim 12 , wherein:
 the biasing member urges a first end portion of the clamp plate axially along the central pillar to bias the clamp plate toward the engaged state; and   with the clamp plate adjusted to the engaged state, a second end portion of the clamp plate opposite the first end portion is movable along the central pillar to adjust the clamp plate toward the disengaged state.   
     
     
         21 . The adjustable support of  claim 20 , wherein the second end portion of the clamp plate comprises a grasping portion that is graspable by a user exterior the collar for manually adjusting the clamp plate between the engaged state and the disengaged state.
