Maneuverable service door for beverage dispensing machines

Abstract

A beverage dispensing machine which defines a service opening through which beverage dispensing equipment is accessible to an operator includes a service door on a housing that is movable between an open position, such that the beverage dispensing equipment is accessible to an operator via the service opening, and a closed position, such that the service door closes the service opening so that the beverage dispensing equipment is inaccessible to the operator. A display panel on the service door displays operational characteristics of the beverage dispensing equipment. When the service door is in the open position the display panel is maneuverable so that the display panel is angled towards the service opening so that an operator can view the display panel while accessing the beverage dispensing equipment via the service opening.

DETAILED DESCRIPTION OF THE DRAWINGS

(14) FIGS. 1-12 depict an example beverage dispensing machine 10 that includes a doors apparatus 35 configured to allow an operator to view a display panel 90 while working on beverage dispensing equipment 12 enclosed by a housing 20. The beverage dispensing equipment 12 (see FIG. 7) is accessible to an operator though a service opening 30 after the door apparatus 35 is maneuvered away from the service opening 30.

(15) The housing 20 houses the beverage dispensing equipment 12 for the beverage dispensing machine 10 and defines the service opening 30 through which the beverage dispensing equipment 12 is accessible to an operator (see FIG. 7). The housing 20 has a left side 22 and a right side 24 that are on opposite sides of the service opening 30.

(16) The door apparatus 35 is coupled to the housing 20 and includes a service door 40 and the display panel 90. The service door 40 is movable between an open position 42 (see FIGS. 7 and 8) wherein the beverage dispensing equipment 12 is accessible to an operator via the service opening 30 and a closed position 44 (see FIGS. 1 and 2) wherein the service door 40 closes the service opening 30 so that the beverage dispensing equipment 12 is inaccessible to the operator. As the service door 40 is moved between the open position 42 and the closed position 44, the service door 40 can move into intermediate positions between the open position 42 and the closed position 44 such as a first intermediate position 101 (see FIGS. 3 and 4) and a second intermediate position 102 (see FIGS. 5 and 6). The service door 40 has a left side 50, a right side 52, an inner side 46 that faces the housing 20 when the service door 40 is in the closed position 44, and an outer side 48 that faces away from the housing 20 when the service door 40 is in the closed position 44 (see FIG. 2). The display panel 90 is coupled to the outer side 48 of the service door 40 and is configured to display an operational characteristic of the beverage dispensing equipment 12 to the operator when the service door 40 is in the closed position or open position. The display panel 90 can display any type of operational characteristic such as operating status, maintenance instructions, and/or the like via any suitable type of device such as a video board, a LCD screen, a touch screen, a graphic picture, and/or the like.

(17) When the service door 40 is in the open position 42 the display panel 90 is maneuverable so that the display panel 90 is angled towards the service opening 30. (see FIG. 7). In this position, the operator can view the display panel 90 while accessing the beverage dispensing equipment 12 via the service opening 30. In some examples, the both the service door 40 and the display panel 90 are maneuverable and/or pivotable so that the display panel 90 is angled towards the service opening 30. The service door 40 pivots about a first pivot axis 56 between the open position 42 and the closed position 44. (see FIGS. 3 and 5) When the service door 40 is in the open position 42 (see FIG. 7), the service door 40 and display panel 90 are pivotable about a second pivot axis 58 so that the display panel 90 is angled towards the service opening 30.

(18) Referring to FIG. 9, the door apparatus 35 includes a pivot arm 70 which couples the service door 40 to the housing 20. (see FIGS. 4 and 6). The pivot arm 70 includes a first end 72 that is coupled to the housing 20 at the first pivot axis 56 and a second end 74 that is coupled the service door 40 at the second pivot axis 58. In some examples, the pivot arm 70 is coupled to the left or right side 22, 24 of the housing 20 so that pivoting of the service door 40 about the first pivot axis 56 from the open position 42 to the closed position 44 completely closes the service opening 30. The pivot arm 70 is coupled to the service door 40 between the left and right sides 50, 52 so that the second pivot axis 58 located between the left and right sides 50, 52.

(19) In the illustrated example, the pivot arm 70 includes an upper support member 76 and a lower support member 78 that each extend between the first and second pivot axes 56, 58. A vertical support plate 80 extends between the upper support member 76 and the lower support member 78, and vertical pivot brackets 82 couple the upper and lower support members 76, 78 to the housing 20 and the service door 40, respectively.

(20) Referring to FIGS. 10-12, a latch 60 latches the service door 40 into the closed position 44. The latch 60 is configured to align the service door 40 with the service opening 30 such that the service door 40 aligns with and closes the service opening 30 despite sag occurring in the pivot arm 70 due to the weight of the door apparatus 35. The latch 60 includes a first camming surface 62 on the service door 40 and a second camming surface 64 on the housing 20 (the second camming surface 64 is depicted in dashed lines; the second camming surface 64 in the example depicted by FIGS. 10-12 is on the inside surface of the housing 20). The first camming surface 62 and second camming surface 64 are curved. When the service door 40 is moved from the open position 42 towards the closed position 44, the first camming surface 62 is cammed upwardly by the second camming surface 64 to squarely align the service door 40 with the service opening 30.

(21) Referring to FIGS. 4, 6, and 8-9, a guide bar 110 pivotally couples the door apparatus 35 to the housing 20. The guide bar 110 is coupled to the inner side 46 of the service door 40 by a first guide bracket 112 at a fourth pivot axis 118 and the housing 20 by a second guide bracket (not shown) at a third pivot axis 116. The guide bar 110 controls the rotation of the service door 40 and the display panel 90 about the first pivot axis 56 and the second pivot axis 58 as the service door 40 and the display panel 90 move between the open position 42 and the closed position 44. The third pivot axis 116 is offset and parallel to the first pivot axis 56 adjacent to the housing 20, and the fourth pivot axis 118 is offset and parallel to second pivot axis 58 along the inner surface 46 of the service door 40. The guide bar 110 can be disconnected the door apparatus 35 and/or the housing 20 to allow the door apparatus 35 to freely rotate.
