Adjustable attachment system

Abstract

An adjustable attachment system is provided for attaching a unit to a base. The adjustable attachment system comprises an embed, a bridging clip and a locking strip. The bridging clip is adapted for receiving an attachment piece, to which the unit may be attached. The embed is positioned in an outward facing surface of the base. The bridging clip is positioned in the embed at a desired in/out position. The position of the bridging clip may be adjusted in two orthogonal directions. The locking strip is inserted between the bridging clip and the embed to fix the bridging clip in place.

1 . An adjustable attachment system comprising: 
 an embed for positioning in a base;    a bridging clip configured for insertion in the embed and adapted for coupling to a unit; and    a locking strip configured for fixing the bridging clip in place in the embed; wherein    the embed and the bridging clip are adapted to engage one another.    
   
   
       2 . The adjustable attachment system of  claim 1 , wherein the embed and the bridging clip are adapted to engage one another via teeth provided on a surface of the embed and teeth provided on a surface of the bridging clip.  
   
   
       3 . The adjustable attachment system of  claim 1 , further comprising end closure arms for positioning along lateral ends of the embed.  
   
   
       4 . The adjustable attachment system of  claim 3 , further comprising end seals for positioning between the end closure arms and the embed. .  
   
   
       5 . The adjustable attachment system of  claim 1 , wherein the embed further comprising upper and lower lips extending along a front face of the embed.  
   
   
       6 . The adjustable attachment system of  claim 1 , wherein the bridging clip comprises an insertion portion and an end portion, the end portion being adapted to receive an attachment piece to which the unit may attached.  
   
   
       7 . The adjustable attachment system of  claim 6 , wherein the insertion portion comprises a planar portion and an angled portion.  
   
   
       8 . The adjustable attachment system of  claim 6 , wherein the end portion comprises a hook portion and an extending portion, the hook portion being adapted to receive the attachment piece.  
   
   
       9 . The adjustable attachment system of  claim 6 , wherein a position of a unit with respect to the attachment system is varied depending on the end portion provided.  
   
   
       10 . The adjustable attachment system of  claim 1 , further comprising an attachment piece configured for attachment to the bridging clip wherein the unit is coupled to the bridging clip via the attachment piece.  
   
   
       11 . The adjustable attachment system of  claim 1 , further comprising fasteners for locking the locking strip in place.  
   
   
       12 . The adjustable attachment system of  claim 1 , wherein a front face of the embed further includes a peel strip.  
   
   
       13 . An adjustable attachment system for attaching a curtainwall unit to a frame, the adjustable attachment system comprising: 
 an embed for positioning in an outward facing surface of the frame;    a bridging clip configured for insertion in the embed;    an attachment piece adapted for coupling the curtainwall unit to the bridging clip; and    a locking strip configured for fixing the bridging clip in place in the embed; wherein    the embed and the bridging clip are adapted to engage one another.    
   
   
       14 . The adjustable attachment system of  claim 13 , wherein the embed and the bridging clip are adapted to engage one another via teeth provided on a surface of the embed and teeth provided on a surface of the bridging clip.  
   
   
       15 . The adjustable attachment system of  claim 13 , wherein a front face of the embed further includes a peel strip.  
   
   
       16 . A curtainwall system comprising the adjustable attachment system of  claim 13 .  
   
   
       17 . A method of attaching a unit to an outward facing surface of a base, the method comprising: 
 positioning an embed in the base;    inserting a bridging clip in the embed;    positioning the bridging clip at a desired position within the embed; and    inserting a locking strip in a space between the bridging clip and the embed.    
   
   
       18 . The method of  claim 17 , further including selecting an end portion for the bridging clip to set the spacing of the unit from the outward facing surface of the base.  
   
   
       19 . The method of  claim 17 , further comprising accessing an interior of the embed by removing a peel strip.  
   
   
       20 . The method of  claim 17 , further comprising engaging the bridging clip in the embed by engaging teeth of the bridging clip with teeth of the embed.  
   
   
       21 . A method of attaching a curtainwall unit to an outward facing surface of a frame, the method comprising: 
 placing an embed in a concrete form;    pouring concrete in the form;    inserting a bridging clip in the embed;    positioning the bridging clip at a desired position within the embed; and    inserting a locking strip in a space between the bridging clip and the embed.
