Definitions
- the present invention relates to a door having a curved profile for display refrigerators and the like.
- Double-glazing unit accommodated inside a supporting frame;
- the double-glazing unit in order to avoid fogging of the outer surface owing to the low internal temperatures which can be estimated at approximately -20/25°C, has on the internal surface of the outer pane a conducting coating which allows the flow of current to heat the pane so as to prevent fogging.
- a flat door of the conventional type is currently used on the front part of which a curved pane is applied which has a perimetric screen-printed region in order to conceal the aluminum profile of the flat door on which it is glued.
- openings form at the upper and lower ends and are closed by means of plastic plugs.
- the aim of the present invention is to solve the above-described problem, by providing a door having a curved profile for display refrigerators and the like in which the door can be provided by means of two or three panes coupled to each other, which directly provide the curved shape of the door without requiring the application of an additional pane.
- an object of the present invention is to provide a door which allows to increase the useful capacity of the refrigerator, in view of the fact that the internal shelves can be curved on their outer edge, thus utilizing the cambered shape of the door.
- Another object of the present invention is to provide a door for vertical freezers which is lighter and aesthetically more pleasing, since it is possible to utilize a pane which has a curved shape.
- Still a further object of the present invention is to provide a door which, in addition to giving the greatest assurances of reliability and safety in use, is advantageous from a purely economical point of view.
- a door having a curved profile for display refrigerators and the like which comprises a double/triple glazing unit supported by a frame, characterized in that said double/triple glazing unit is constituted by an inner pane and an outer pane which is curved so that its convexity is directed outward, said outer pane being formed by low-emissivity pyrolytic glass with a coating layer, on the inner face, which is obtained by means of a deposition of metal oxides, said coating layer being affected by a passage of electric current.
- the door having a curved profile for display refrigerators and the like is generally designated by the reference numeral 1 and comprises a double-glazing unit 2 which is supported by a frame 3 for connection to the structure 4 of the display refrigerator; nothing changes conceptually if a triple glazing unit is used.
- the particularity of the invention is constituted by the fact that the double-glazing unit or triple-glazing unit 2 has an inner pane 10 and an outer pane 11 which is curved so that its convexity is directed outward.
- the inner pane 10 is curved in a similar manner, so as to be substantially parallel.
- the particular characteristic is constituted by the fact that the outer pane 11 is a low-emissivity pyrolytic pane such as those normally manufactured by the companies Glaverbel, Pilkington and Saint Gobain; such panes are currently used for the insulation of glazed areas with double-glazing units or triple-glazing units for windows.
- a low-emissivity pyrolytic pane such as those normally manufactured by the companies Glaverbel, Pilkington and Saint Gobain; such panes are currently used for the insulation of glazed areas with double-glazing units or triple-glazing units for windows.
- panes are manufactured with a low-emissivity coating 12 which is sprayed uniformly.
- the coating 12 is arranged on the inner face of the outer pane 11 and is obtained by means of a deposition of metal oxides at high temperatures which has the characteristic that it does not damage during the curving of the pane.
- screen-printed portions 15 are applied at the upper and lower edges and provide the contacts for connection to an electrical power supply which, by utilizing the electrical resistance of the coating 12, provides a flow of current which allows to perform the intended heating of the pane in order to prevent its fogging.
- the electrical power supply at 220 or 110 volts is preferably provided by means of a transformer 20 so as to obtain the power required to heat the pane according to the electrical resistance, which varies according to the dimensions and type of pane used, since the various manufacturers use a coating which has different electrical resistance characteristics.
- the structure has two posts 30 which have a seat 31 for the engagement of a magnetic gasket 32 and which are joined, at their ends, by lower and upper cross-members which are designated by the reference numeral 35 and are connected to the posts by means of L-shaped elements 36.
- the cross-members 35 which run along the chord of the curved outer profile of the door formed by a double-glazing unit 40 which engages seats 41 of the posts 30, couple to a trim profile 42 which supports the magnetic gasket 32.
- an internal plug 50 which is connected to one side of the cross-member and forms a seat 51 for containing a profile 52 which delimits the region that accommodates the insulation 53, which is contained, on the other side, by an outer plug 55 which is fixed to the outer edge of the cross-member and forms an outer seat 56 for the insertion of a flexible flat profile 57 which overlaps the upper edge of the pane.
- the resulting arrangement which can also be used for refrigerators with an internal temperature of 0 to 5°, has a particularly pleasant finish, and the presence of the flexible flat profiles that couple to the pane allows to provide a finishing element which does not have technical sealing functions, thus allowing to have a significant cost reduction.
- the materials employed may be any according to requirements.
