Abstract
A refrigerated showcase characterized in that curtains superposed on each other in a plurality of layers so that an air layer or layers may intervene therebetween, are equipped along a front surface of a path of a cold air flow for refrigerating goods within the showcase, across the front opening of the body of the refrigerated showcase. Spacers are provided on the curtains in order to maintain the curtains in spaced relationship.
Claims7
In a refrigerated showcase, having a front opening, in which a cold air flow for refrigerating goods within the showcase is provided along a front surface thereof across the front opening, the improvement comprising:
- a plurality of spaced flexible continuous gas-impermeable curtains having mutually facing surfaces, respectively freely hanging from the showcase along a top edge thereof, each extending across the entire front opening of the showcase so as to prevent fluid communication between the interior of the showcase, including the cold air flow, and the environmental atmosphere exterior to the showcase;
- and
- spacer means, fixed to and movable with one of the curtains at the facing surface thereof for separating the plurality of curtains from each other so as to maintain a continuous air space therebetween.
In a refrigerated showcase having a front opening, in which cold air flow for refrigerating goods within the showcase is provided along a front surface thereof across the front opening, the improvement comprising:
- a plurality of spaced flexible continuous gas-impermeable curtains having mutually facing surfaces, respectively freely suspended from the showcase alone a top edge thereof, each curtain extending across the entire front opening of the showcase so as to prevent fluid communication between the interior of the showcase, including the cold air flow, and the environmental atmosphere exterior of the showcase;
- and
- spacer means, fixed to and movable with at least one of the curtains at the facing surface thereof, for preventing the cold air flow from blowing any of the plurality of curtains into contact with another, so as to maintain a continuous air space between each pair of adjacent ones of the plurality of curtains.
In a refrigerated showcase having a horizontal upper edge and a horizontal lower edge below and horizontally outward displaced with respect to the upper edge, the upper and lower edges defining front opening therebetween in which cold air flow for refrigerating goods within the showcase is provided along a front surface thereof extending inclined to the vertical across the front opening, the improvement comprising:
- a plurality of spaced flexible continuous gas-impermeable curtains, including an outer curtain and an inner curtain, having mutually facing surfaces, respectively connected to the showcase along a top edge thereof, each curtain extending across the entire front opening of the showcase so as to prevent fluid communication between the interior of the showcase, including the cold air flow, and the environmental atmosphere exterior to the showcase, the outer curtain at its bottom end being draped across the lower edge of the showcase, the inner curtain hanging freely behind the outer curtain, whereby the cold air flow is prevented from blowing the inner curtain into contact with the outer curtain, so as to maintain a continuous air space between the inner curtain and the outer curtain.
