DETAILED DESCRIPTION OF THE INVENTION
The following description is provided in relation to several examples which may share common characteristics and features. It is to be understood that one or more features of any one example may be combinable with one or more features of the other examples. In addition, any single feature or combination of features in any of the examples may constitute additional examples.
FIG. 1 is a schematic view of a dishwasher 5 for washing and/or drying crockery items, such as dishes, frying pans, cookie sheets, cutting boards, bowls, pots, etc., and/or glasses and cups, e.g., wineglasses. The dishwasher 5 may include a manually openable door 10 and a compartment 15. The door 10 may be openable to allow access to the compartment 15. The door 10 may form a generally water/air tight seal relative to the compartment 15 when closed. The compartment 15 may include at least one rack 20.
FIG. 2 shows a perspective view of the rack 20. The rack 20 may be any type of rack capable of supporting items that are to be cleaned and/or dried and may be, for example, a wire-type rack. The rack 20 may include side walls 25, which in the case of a wire-type rack, may include one or more horizontally oriented wires 30. In addition, one or more of the side walls 25 (and/or bottom wall) may support one or more stemware holders 35 that securely hold stemware in place within the rack 20. Each of the stemware holders 35 may be permanently or detachably attached to one of the side walls 25 and may include one or more prong units 40 for holding an individual piece of stemware. Each prong unit 40 may be connected to a common central shaft 45.
As illustrated in FIGS. 3 and 4, each prong unit 40 may have a holding side 50 for holding a piece of stemware and a securing side 55 for securing the prong unit 40 to the rack 20. The holding side 50 may include two outer holding prongs 60 and an inner holding prong 65 projecting from the central shaft 45. The outer holding prongs 60 may have an unbent shape and may project from the central shaft 45 along a first plane 70. The inner holding prong 65 may be positioned between the outer holding prongs 60 and may have a bent shape. A base portion 75 of the inner holding prong 65 may connect the inner holding prong 65 to the central shaft 45, while an engaging portion 80 of the inner holding prong 65 may extend from the base portion 75. The engaging portion 80 may extend along a second plane 85 that is offset and parallel to the first plane 70. As illustrated in FIG. 5, when the holding side 50 holds a piece of stemware 87, the shaft of the stemware 87 may be perpendicular to first and second planes 70 and 85.
Referring back to FIGS. 3 and 4, the structure of the securing side 55 may mirror the structure of the holding side 50. Accordingly, the securing side 55 may include two outer securing prongs 90 and an inner securing prong 95 projecting from the central shaft 45 and extending away from the holding side 50. Similar to the outer holding prongs 60, the outer securing prongs 90 may have an unbent shape and may project along a third plane 100. The inner securing prong 95 may be positioned between the outer securing prongs 90 and may have a bent shape. A base portion 105 of the inner securing prong 95 may connect the inner securing prong 95 to the central shaft 45, while an engaging portion 110 of the inner securing prong 95 may extend from the base portion 105. The engaging portion 110 may extend along a fourth plane 115 that is offset and parallel to the third plane 100.
The central shaft 45 may be horizontally oriented and may form a core of the stemware holder 35. A single central shaft 45 may form the core of multiple prong units 40 or the core of only one prong unit 40. In addition, the prongs of the holding side 50 and the prongs of the securing side 55 of a particular prong unit 40 may be attached to the central shaft 45 in a manner to form a fixed angle α. The angle α may range from
45-175 degrees, and in one example may be any angle greater than about 90 at which the stemware holder 35 may securely hold one or more pieces of stemware 87 (e.g., 105, 120, 135, 150 and 165 degrees). As illustrated in FIG. 5, when secured to the side wall 25, the securing portion 55 may be oriented so that the third and fourth planes 100 and 115 are substantially parallel to a direction in which the side wall 25 extends. Due to the orientation of the prongs on the holding side 50 relative to the prongs on the securing side 55, the stemware holder 35 may hold the stemware 87 at an angle β relative to an inner surface of the side wall 25 that faces an interior of the rack 20. In particular, the stemware 87 may form the angle β with a plane 120 that is parallel to the inner surface of the side wall 25. In addition, the angle β may be less than 90 degrees less, and/or less than the angle α. By holding the stemware 87 at the angle β and/or appropriately dimensioning the prong unit 40 relative to the size of the stemware 87 and or the rack 20, contact between the stemware 87 and the bottom of the rack 20 may be avoided. Avoiding contact between the stemware 87 and the bottom of the rack 20 may reduce the likelihood damage to the stemware 87 during the cleaning process. Furthermore, suspending the stemware 87 above the bottom of the rack 20 may reduce the likelihood of or prevent the formation of large water spots during the drying process.
In an alternate configuration, the central shaft 45 may be a hinge 46 (see FIG. 8) that is rotatable around a central longitudinal axis 125. Accordingly, in this configuration, the angle α (as well as the angle β) may be variable. The variable angle α (and angle β) may accommodate stemware of different sizes so that regardless of the size of the stemware 87, the stemware holder 35 may be able to hold the stemware 87 and avoid any contact between the stemware 87 and the bottom surface of the rack 20. In the form of a hinge, the central shaft 45 may be lockable at one or more preset angles within the range of about 45-180 degrees, or about 90 to 180 degrees (e.g., 105, 120, 135, 150 and 165 degrees).
The components of the stemware holder 35 may be made from any material capable of withstanding the conditions inside the dishwasher 5 during cleaning and drying cycles. For example, the components of the stemware holder 35 may be made from the same material as the rack 20. Alternatively, the components of the stemware holder 35 and the rack 20 may be made from different materials. In addition, the holding prongs, securing prongs and the central shaft 45 may be made from the same material, or different materials.
In addition, the stemware holder 35 may be formed integrally to the rack 20 (i.e., the stemware holder 35 may be formed from one piece with the rack 20). Alternatively, the stemware holder 35 may be formed separately from the rack 20 and later permanently or detachably attached to the rack 20. Further, the stemware holder 35 may be retroactively fitted to a conventional dishwasher rack.
As illustrated in FIGS. 2 and 5, the outer securing prongs 90 and the inner securing prong 95 may form a receiving space 130 for receiving the side wall 25 and may operate in concert to secure the stemware holder 35 to the side wall 25. The receiving space 130 may extend in a direction parallel to the plane 100. In addition, a distance d between the outer securing prongs 90 and the engaging portion 110 may substantially correspond to a thickness of the side wall 25 so that the side wall 25 may be tightly received by the receiving space 130, thereby minimizing the movement of the side wall 25 within the stemware holder 35.
When the side wall 25 is received by the stemware holder 35, the base portion 105 of the inner securing prong 95 may contact an upper surface of the side wall 25. Accordingly, the base portion 105 may be the portion of the stemware holder 35 that rests on the side wall 25 when the stemware holder 35 is attached to the side wall 25. However, because the base portion 105 may be offset from the center of mass (the central shaft 45) of the stemware holder 35 and may be offset from the center of mass of the stemware 87 being held by the stemware holder 35, the stemware holder 35 may have a tendency to rotate around the contact point between the upper side of the side wall 25 and the base portion 105. This rotational tendency may cause the outer securing prongs 90 to be forced against the side wall 25. A length of the outer securing prongs 90 may be selected so that the outer securing prongs 90 may use the side wall 25 to resist any rotational movement of the stemware holder 35. For example, when the rack 20 is a wire rack, the length of the outer securing prongs 90 may be selected so that the outer securing prongs 90 may engage at least two horizontal wires 30. In addition, a length of the engaging portion 110 may be sized to prevent the side wall 25 from slipping out of the receiving space 130.
In an alternate embodiment, the securing side 55 of the stemware holder 35 may be omitted and the central shaft 45 may be secured to the side wall 25. In examples omitting the securing side 55, the central 45 may be secured to the side wall 25 via, for example, a weld, an adhesive, mechanical fasteners or any other method or device capable of withstanding the conditions encountered during the cleaning and drying cycles of the dishwasher. Also, instead of being secured to the side wall 25, the central shaft 45 may be a part of the side wall 25. For example, in an embodiment in which the rack 20 is a wire rack, the central shaft 45 may be an uppermost horizontally oriented wire 30 (see FIG. 9). It should be understood that all configurations omitting the securing side 55 may or may not include a hinge as the central shaft 45. In other words, for all configurations without the securing side 55, the angle α (and the angle β) may be fixed or variable.
As illustrated in FIGS. 5-7, the holding side 50 of the stemware holder 35 may receive a base 135 of a piece of stemware 87. The base 135 may be received by a receiving space 140 defined by the outer holding prongs 60 and the inner holding prong 65. The receiving space 140 may extend in a direction parallel to the plane 70. In addition, a distance D between the outer holding prongs 60 and the engaging portion 80 may substantially correspond to a thickness of the base 135 so that the base 135 may be tightly received by the receiving space 140, thereby minimizing the movement of the base 135 within the stemware holder 35.
Upon receiving the stemware 87, the outer holding prongs 60 may support the stemware 87. A distance between the outer holding prongs 60 may be wide enough to allow a stem 145 of the stemware 87 to pass between the outer holding prongs 60. At the same time, the distance between the outer holding prongs 60 may be smaller than a diameter of the base 135 so that the base may not slip between the outer holding prongs 60.
Because the outer holding prongs 65 may support the stemware 87 at the angle β, and because the stemware 87 may be supported so that the stemware 87 does not rest on the bottom of the rack 20, the stemware 87 may have a tendency to rotate around an axis passing through distal ends 150 of the outer holding prongs 65 and may fall off of the outer holding prongs 65. The engaging portion 80 of the inner holding prong 65 may be positioned anywhere between the outer holding prongs 65 that may enable the engaging portion 80 to counteract the rotating tendency of the stemware 87 and retain the stemware 87 within the receiving space 140. For example, the inner holding prong 60 may be positioned at a location corresponding to the stem 145 of the stemware 87. In addition, the base portion 75 of the inner holding prong 65 may form a barrier against which the base 135 of the stemware 87 may rest.
While the technology has been described in connection with what are presently considered to be the most practical and preferred examples, it is to be understood that the technology is not to be limited to the disclosed examples, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the disclosure.
