Double-walled acrylic door for refrigerated cabinets

Abstract

A door for a refrigerated cabinet is double-walled with two transparent walls ( 2 ). The two transparent walls ( 2 ) are produced from flat plastic panels. The door ( 1 ) includes one or more inserts ( 3, 4 ) which are positioned on the circumference of the two transparent walls ( 2 ) and hold the two transparent walls ( 2 ) parallel to one another at a predefined distance (d) from one another. The door ( 1 ) is designed in such a way that an optimum view without distortion is provided of the products behind the door ( 1 ). The door ( 1 ) is insulating and condensation-free.

         17 . A door for a refrigerated cabinet, wherein the door is double-walled with two transparent walls, wherein
 the two transparent walls are produced from flat plastic panels,   and the door comprises one or more inserts which are positioned on the circumference of the two transparent walls and hold the two transparent walls parallel to one another at a predefined distance from one another,   and wherein the two transparent walls are flat acrylic panels and the two transparent walls and the one or more inserts are joined to one another with an elastic joining material.   
     
     
         18 . The door of  claim 17 , wherein the one or more inserts are transparent. 
     
     
         19 . The door of  claim 17 , wherein the inserts are made from a composite material, a carbon-fibre-based material, an aluminum-based material, or a combination thereof. 
     
     
         20 . The door of  claim 18 , wherein the two transparent walls are flat acrylic panels, and the two transparent walls and the one or more inserts are bonded with an optically transparent material. 
     
     
         21 . The door of  claim 17 , wherein the one or more inserts are extruded profiles. 
     
     
         22 . The door of  claim 17 , wherein the one or more inserts are mounting inserts which are provided with a mounting recess for assembly of a hinge. 
     
     
         23 . The door of  claim 17 , wherein one or more inserts are mounting inserts which are provided with mounting facilities for hinge adapters. 
     
     
         24 . The door of  claim 22 , wherein the mounting inserts are injection moulding pieces. 
     
     
         25 . The door of  claim 17 , wherein the transparent walls are acrylic panels with a thickness of 2-5 mm, for example 3 mm or 4 mm. 
     
     
         26 . The door of  claim 17 , wherein one or both transparent walls are coated with an anti-scratch layer. 
     
     
         27 . The door of  claim 17 , wherein one or both transparent walls are coated with an anti-reflective layer. 
     
     
         28 . The door of  claim 17 , wherein one or both transparent walls are coated with a heat-reflecting layer. 
     
     
         29 . A method for producing a door for a refrigerated cabinet, wherein the door is double-walled with two transparent walls, comprising:
 providing two flat plastic panels with predefined dimensions, providing one or more inserts,   and bonding the one or more inserts on the circumference of the two flat plastic panels with an elastic joining material,   wherein the two flat plastic panels form the two transparent walls of the door which stand parallel to one another at a distance predefined by the one or more inserts.   
     
     
         30 . The method of  claim 29 , wherein the one or more inserts are mounting inserts which are provided with a mounting recess and the method further comprises:
 mounting a hinge or hinge part in the mounting recess.   
     
     
         31 . The method of  claim 29 , wherein the one or more inserts are mounting inserts which are provided with mounting facilities for hinge adapters, and the method further comprises:
 mounting a hinge adapter.   
     
     
         32 . A refrigerated cabinet for displaying sales items, comprising a frame structure and one or more doors according to  claim 17  rotatably positioned in the frame structure. 
     
     
         33 . The door of  claim 19 , wherein the two transparent walls are flat acrylic panels, and the two transparent walls and the one or more inserts are bonded with an optically transparent material. 
     
     
         34 . The door of  claim 23 , wherein the mounting inserts are injection moulding pieces.
