Embodiment Construction

[0034] refer to figure 1 , describing the function of the left-hand side shield. A loaded torsion spring assembly (17) is packaged inside the roller shade unit (19). The loaded torsion spring assembly (17) is used to uniformly retract the fabric (12) into the roller shade unit (19). The top of the vertical beam (14) is provided with a pulley connected to the vertical beam connection point (1), and the pulley cable (6) is connected with the pulley. Then the pulley cable (6) is extended through the frame and connected to the weight (3). A weight (3) is used as a constant load. This load constantly pulls the vertical beam (14), thereby maintaining the vertical beam (14) in the closed position at the center line (4) by the stop. When the vertical beam (14) is pushed away from the center line (4), the weight (3) slides freely upwards inside the roller blind unit (20). When the vertical beam (14) is released, the constant load exerted by the weight (3) pulls the vertical beam (...

Abstract

There is described a horizontally slidable self-closing screen assembly which comprises at least one screen material connected to a roller biasing the screen to an open position, the roller being operably connected to a counterweight and wherein the load provided by the weight is greater than the force provided by the roller biasing the screen. There are also described a housing unit containing the slidable screen assembly and a cabinet fitted with such a housing unit.

Description

technical field [0001] The present invention relates to a new type of roller shade, a new device and related methods. [0002] More particularly, the present invention relates to novel roller blinds and the desire to separate products from consumers at selected times, for example in conjunction with display cases such as refrigerated or refrigerators, tobacco or beverage cabinets and such like cabinets. The new roller blind system. Background technique [0003] There are many reasons why it is desirable to shade merchandise or products, ie, goods displayed in a retail environment, especially if they are to be stored in a refrigerator or freezer. For example, due to increased restrictions on carbon emissions and carbon footprint, the need to provide insulation panels for refrigerators and freezers has also increased. Currently, tens of thousands of supermarket freezers in the UK alone are open, ie without doors or any other form of closure. This results in a huge waste of ...
