Abstract

An attachment for a hair styling apparatus includes an air inlet for receiving airflow from the hair styling apparatus, an air outlet and a duct for conveying air from the air inlet to the air outlet, wherein at least part of an external surface of the duct comprises an arrangement of tactile ribbed protrusions. The ribbed surface provides thermal insulation from the duct which may become warm when heated airflow is received from the hair styling apparatus and also serves as a visual guide to the user as to where they should place their fingers when grasping the attachment.

1 . An attachment for a hair styling apparatus comprising:
 an air inlet for receiving airflow from the hair styling apparatus;   an air outlet; and   a duct for conveying air from the air inlet to the air outlet, wherein at least part of an external surface of the duct comprises an arrangement of tactile protrusions and the tactile protrusions comprise a series of parallel, elongate ribs, each rib having a height, h, and a width, w, and a distance, d, between adjacent ribs.   
     
     
         2 . The attachment of  claim 1 , wherein the air outlet is an elongate slot. 
     
     
         3 . The attachment of  claim 1 , wherein the height, h, of each rib is in the range of 0.5 mm to 2.5 mm. 
     
     
         4 . The attachment of  claim 3 , wherein the height, h, of each rib is in the range of 0.8 mm to 1.2 mm. 
     
     
         5 . The attachment of  claim 1 , wherein the distance, d, between each rib is in the range of 0.5 mm to 2.5 mm. 
     
     
         6 . The attachment of  claim 5 , wherein the distance, d, between each rib is in the range of 1.3 mm to 1.7 mm. 
     
     
         7 . The attachment of  claim 1 , wherein the width, w, of each rib is in the range of 0.5 mm to 2.0 mm. 
     
     
         8 . The attachment of  claim 7 , wherein the width, w, of each rib is in the range of 0.8 mm to 1.2 mm. 
     
     
         9 . The attachment of  claim 1 , further comprising a side wall on each narrow edge of the duct, wherein each side wall extends from an end of the air outlet slot towards the air inlet. 
     
     
         10 . The attachment of  claim 9 , wherein the arrangement of tactile protrusions is disposed on an external surface of the side wall. 
     
     
         11 . The attachment of  claim 1 , wherein the air inlet is circular in shape. 
     
     
         12 . The attachment of  claim 1 , wherein the air inlet comprises at least one slot. 
     
     
         13 . The attachment of  claim 12 , wherein the air inlet comprises an annular slot.
