Vacuum Hose Attachment

Abstract

A vacuum appliance having a housing with an attached intake port. A plurality of attachment nodes are axially located about the intake port. An accessory with a plurality of axially located grooves selectively engage the plurality of attachment nodes to establish a locking relationship with the intake port.

1 . A vacuum appliance, comprising:
 a housing;   an intake port fixedly attached to said housing;   a first plurality of attachment nodes radially spaced about said intake port at a proximal end, wherein a distal end of said intake port further comprises an elongated portion adjacent to and axially spaced from said plurality of attachment nodes, said elongated portion having a continuous generally tubular surface having a diameter smaller than said proximal end; and   an accessory having proximal and distal ends, said proximal end comprising a plurality of axially located grooves for selectively engaging said plurality of attachment nodes to establish a locking relationship with said intake port.   
   
   
       2 . The vacuum appliance of  claim 1 , wherein said locking relationship creates a vacuum seal between said accessory and said intake port. 
   
   
       3 . The vacuum appliance of  claim 1 , wherein said distal end of said accessory comprises a tool for transporting debris into the vacuum appliance. 
   
   
       4 . The vacuum appliance of  claim 1 , wherein said distal end of said accessory comprises a second plurality of attachment nodes axially located about said distal end. 
   
   
       5 . The vacuum appliance of  claim 4 , wherein said second plurality of attachment nodes is integrally formed on the exterior of said distal end of said accessory. 
   
   
       6 . The vacuum appliance of  claim 4 , wherein said distal end of said accessory comprises a tool for transporting debris into the vacuum appliance. 
   
   
       7 . The vacuum appliance of  claim 1 , wherein said axially located grooves are open at an end surface of said proximal end. 
   
   
       8 . The vacuum appliance of  claim 7 , wherein said plurality of axially located grooves are spirally configured. 
   
   
       9 . The vacuum appliance of  claim 8 , wherein said spirally configured grooves extend at an angle of about 30 degrees to about 60 degrees. 
   
   
       10 . The vacuum appliance of  claim 9 , wherein said spirally configured grooves assist in breaking said vacuum seal upon removal of said accessory. 
   
   
       11 . The vacuum appliance of  claim 4 , wherein said distal end of said accessory further comprises a second elongated portion adjacent to said second plurality of attachment nodes, said second elongated portion having a generally tubular surface. 
   
   
       12 . The vacuum appliance of  claim 11 , wherein said generally tubular surface of said second elongated portion engages a friction fit accessory. 
   
   
       13 . The vacuum appliance of  claim 1 , wherein said continuous generally tubular surface of said elongated portion is tapered. 
   
   
       14 . A vacuum appliance attachment mechanism, comprising:
 a vacuum appliance;   an intake port attached to said vacuum appliance, said intake port having a proximal end attached to said vacuum appliance, an intermediary portion with a plurality of axially located attachment nodes and an elongated distal end, wherein said elongated distal end has a continuous generally tubular surface adapted to be engaged by standard friction fit accessories; and   a vacuum accessory having a plurality of axially located spiral grooves for receivable attachment to said plurality of axially located attachment nodes of said intermediary portion.   
   
   
       15 . The vacuum appliance attachment mechanism of  claim 14 , wherein said attachment nodes are integrally formed exterior to said intermediary portion. 
   
   
       16 . The vacuum appliance attachment mechanism of  claim 14 , wherein said vacuum accessory transports debris into said vacuum appliance. 
   
   
       17 . The vacuum appliance attachment mechanism of  claim 14 , further comprising a vacuum seal at said attachment of said intake port and said vacuum accessory. 
   
   
       18 . The vacuum appliance attachment mechanism of  claim 14 , wherein said intake port is disposed on a distal end of a hose attached to said vacuum appliance. 
   
   
       19 . The vacuum appliance attachment mechanism of  claim 14 , wherein said intake port is disposed on a housing of said vacuum appliance. 
   
   
       20 . The vacuum appliance attachment mechanism of  claim 14 , wherein said continuous generally tubular surface of said elongated distal end is tapered.
