Telescopic cup tray for a beverage machine
The present invention concerns a food and beverage preparation machine ( 1 ) comprising a machine body ( 2 ), a fluid system for preparing and dispensing a beverage, a beverage dispensing opening, and a cup tray ( 6 ) attached to the machine body in at least two possible height positions. According to the invention, the machine comprises a pit ( 7 ) with a cylindrical opening located below a dispensing opening, said cylindrical opening comprising at least one guiding pin ( 8 ), and the cup tray comprises a horizontal plate ( 10 ) and a vertical cylinder ( 11 ), the cylinder having a vertical cam groove ( 12 ) adapted to receive said guiding pin in a slidable manner for displacing the cup tray in height, and superimposed horizontal groove branches ( 13 ) extending from the vertical groove, advantageously through lower and upper curved camways defining a cusp-shaped cam path, for fixing the cup tray at predetermined height positions.
1. A food and beverage preparation machine comprising a machine body, a fluid system adapted to mix a fluid with an ingredient for the preparation of a food or beverage product, and a dispensing opening for delivering the food or beverage into a cup or other receptacle, and further comprising a cup tray that can be attached to the machine body in at least two alternative height positions relative to the dispensing opening:
the machine body comprises a pit with a cylindrical opening located below the dispensing opening, the cylindrical opening comprising at least one guiding pin extending inwardly from the pit's opening peripheral edge, and
the cup tray comprises a horizontal plate and a cylinder extending vertically downwardly therefrom, the outer surface of the cylinder having at least one vertical cam groove adapted to receive the guiding pin in a slidable manner for displacing the cup tray in height, and at least two discrete superimposed horizontal groove branches extending from the vertical groove, for fixing the cup tray at predetermined height positions.
2. A machine according to claim 1 , wherein each horizontal groove branch extends horizontally from the vertical cam groove through lower and upper curved camways defining a cusp-shaped cam path.
3. A machine according to claim 1 , wherein the cup tray cylinder is hollow and has one lower end closed, and one upper end opened through the plate, the opening being covered by a removable grid.
4. A machine according to claim 1 , which is a beverage preparation machine adapted for use with at least one ingredient container.
5. A machine according to claim 1 , wherein the ingredient is the group consisting of: roast and ground coffee, powdered or liquid soluble coffee, powdered or liquid soluble dairy ingredient, soluble tea, leaf tea, soup, syrup, powder, liquid and gel nutritional compositions.
6. A machine according to claim 1 , wherein the pit comprises at least one vertical ramp protruding inwardly towards the middle of said pit, adapted to cooperate with at least one corresponding latching pin mounted on a flexible strip of the cylinder, so as to form a latch mechanism for releasably locking the tray in each of its height positions.
7. A machine according to claim 6 , wherein the pit comprises three equidistant ramps and the cylinder comprises three corresponding equidistant flexible strips.
