Benefits of technology

The present invention provides a door for a refrigerated cabinet that is double-walled with two transparent walls. The two transparent walls are made from flat plastic panels, and the door comprises one or more inserts which hold the two transparent walls parallel to each other at a predefined distance from one another. The two transparent walls and the one or more inserts are joined together with an elastic joining material, which prevents distortion due to uneven temperatures during use. This design is simple and economical, and also provides good insulation. The invention also provides a method for producing a door for a refrigerated cabinet using flat plastic panels and inserts that can be easily attached together.

Problems solved by technology

However, due to the thermoforming, these doors nearly always produce a disturbing visual distortion due to the inconsistent thickness of one or both plastic layers.
In the past, multi-layer plastic doors have also been designed, but these have the disadvantage that they very quickly become warped due to, inter alia, temperature variations.

Embodiment Construction

[0015]The present invention, referred to below as a “door”, is especially suitable for the covering of multi-deck refrigerated cabinets (for example chests) of the type increasingly used in supermarkets for the sake of a higher energy saving. One aspect of the present invention is a refrigerated cabinet for displaying sales items or products, which comprises a frame structure and one or more doors 1 positioned rotatably in the frame structure according to one of the embodiments described below.

[0016]The door 1 will be produced in various lengths, widths and cavity dimensions, wherein, however, the design will be the same for all embodiments. The door 1 has a height of, for example, more than 150 cm, for example 187 cm.

[0017]The door will consist of a number of components as described below, and shown in the attached figures. FIG. 1 shows a simple assembly drawing of a complete, not yet assembled door 1. The door 1 is double-walled with two transparent walls 2, which are made from fl...

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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to double-walled acrylic doors which are used in refrigerated cabinets of supermarkets. It relates above all to (daily) covering of so called multi-deck refrigerated cabinets.PRIOR ART[0002]Various doors have been designed for use in refrigerated cabinets, both single and double-glazed. Doors are also known which are formed from two layers of plastic, wherein one layer is thermoformed in specific moulds. However, due to the thermoforming, these doors nearly always produce a disturbing visual distortion due to the inconsistent thickness of one or both plastic layers. In the past, multi-layer plastic doors have also been designed, but these have the disadvantage that they very quickly become warped due to, inter alia, temperature variations.[0003]The Japanese patent publication JP-2000-105065 discloses a refrigerated compartment with two doors, wherein one door comprises two transparent plastic walls. The walls are kept apart f...
