Method and framework for suspending acoustic absorption medium

Abstract

A quickly erectable framework for supporting a curtain includes at least two standards. Each standard includes a shaft having a capital end and a base end, the base end. A clevis bracket affixed to the capital end of each standard suspends at least one curtain track configured, when the framework is in its erected state, to span horizontally an interspace between the two standards, the track being affixed to each of the capital ends by means of the clevis bracket. A plurality of trolleys is each configured to transit along the track while suspending an edge of a curtain. At least one edge scissor assembly is affixed at opposite ends to span the interspace between the standards. Each scissor assembly includes a plurality of scissor arms hingedly connected to one another.

1 . A quickly erectable framework for supporting a curtain comprising:
 at least two standards, each standard including a shaft having a capital end and a base end, the base end;   one clevis bracket affixed to the capital end of each standard;   at least one curtain track configured, when the framework is in its erected state, to span horizontally an interspace between the two standards, the track being affixed to each of the capital ends by means of the clevis bracket; and   a plurality of trolleys, the trolleys each configured to transit along the track while suspending collectively from the plurality of trolleys an edge of a curtain.   
     
     
         2 . The framework of  claim 1  further comprising
 at least one edge scissor assembly affixed at opposite ends to span the interspace between the standards; each scissor assembly including:
 a plurality of scissor arms hingedly connected to one another, at least two of said scissor arms defining articulating members formed by at least two articulating arm sections that are movable between a folded state when the expandable framework is in the collapsed state and an aligned state when the expandable framework is in the expanded state whereby the two articulating arm sections are generally oriented along parallel axes with respect to one another, each said articulating member having a first outer end pivotally secured to one of said upper and lower mounts of a respective peripherally adjacent said support member. 
 
 
     
     
         3 . The framework of  claim 1 , further comprising:
 a membrane to overdrape the framework thereby forming a tent-like structure.   
     
     
         4 . The framework of  claim 1 , further comprising:
 a transom spanning between one of:
 capital ends of a first and a second standard; 
 a first curtain track and a second curtain track and, the transom adding rigidity to the framework; and 
 a capital end of a standard and a curtain track. 
   
     
     
         5 . The framework of  claim 4 , wherein:
 the transom further provides a fixation for equipment the framework supports.   
     
     
         6 . The framework of  claim 1 , wherein the base of the standard includes a ground engaging device selected from a group consisting of:
 a foot;   an extendable leg;   a spike;   a suction cup;   a glider; and   a caster.   
     
     
         7 . The framework of  claim 1 , wherein the curtain includes acoustic absorption medium. 
     
     
         8 . A method for supporting a curtain from a quickly erectable framework comprising:
 erecting at least two standards, each standard including a shaft having a capital end and a base end, the base end;   affixing one clevis bracket to the capital end of each standard;   affixing to each of the capital ends by means of the clevis bracket at least one curtain track configured, when the framework is in its erected state, to span horizontally an interspace between the two standards; and   suspending a plurality of trolleys on the curtain track, the trolleys each configured to transit along the track while suspending collectively from the plurality of trolleys an edge of a curtain.   
     
     
         9 . The method of  claim 8  further comprising
 affixing at opposite ends to span the interspace between the standards at least one edge scissor assembly; each scissor assembly including:
 a plurality of scissor arms hingedly connected to one another, at least two of said scissor arms defining articulating members formed by at least two articulating arm sections that are movable between a folded state when the expandable framework is in the collapsed state and an aligned state when the expandable framework is in the expanded state whereby the two articulating arm sections are generally oriented along parallel axes with respect to one another, each said articulating member having a first outer end pivotally secured to one of said upper and lower mounts of a respective peripherally adjacent said support member. 
 
 
     
     
         10 . The method of  claim 8 , further comprising:
 overdraping a membrane on the framework thereby forming a tent-like structure.   
     
     
         11 . The method of  claim 8 , further comprising:
 affixing a transom to the framework, the transom adding rigidity to the framework, spanning between one of:
 capital ends of a first and a second standard; 
 a first curtain track and a second curtain track; and 
 a capital end of a standard and a curtain track. 
   
     
     
         12 . The method of  claim 11 , wherein:
 the transom further provides a fixation for equipment the framework supports.   
     
     
         13 . The method of  claim 8 , wherein the base of the standard includes a ground engaging device selected from a group consisting of:
 a foot;   an extendable leg;   a spike;   a suction cup;   a glider; and   a caster.   
     
     
         14 . The method of  claim 7 , wherein the curtain includes acoustic absorption medium.
