ABSTRACT:

FIELD OF THE INVENTION
This invention relates to an accessory to be used in an automatic dishwasher. More particularly, it relates to a mechanism which will adjustably attach to a portion of a dishwasher rack at one end and adjustably attach to the stem of stemmed glassware at the other end to hold the stemmed glassware in an upright and secure position within the rack of the dishwasher.
BACKGROUND OF THE INVENTION
Automatic dishwashers, especially those designed for home use, accomplish the washing and rinsing of glasses, cups, and the like by spraying pressurized streams of water mixed with a detergent over the glassware. Unlike some commercial dishwashers, which may be designed for a particular item, home dishwashers are used for items as diverse as large pots down to small finger sized glasses used for specialized liqueurs. Consequently, the racks within the dishwasher are designed for broad utility for holding a wide variety of items in a dish rack during the spraying action generated by the dishwasher. However, for the dishwashing action to be effective, the stream of the water must have enough pressure to dislodge dried food particles from the items to be washed. This pressure can upset light items such as crystal glassware and especially such items with a high center of gravity like stemware where a large portion of the weight of the item may be in its base and its stem rather than in the liquid retaining bowl. Consequently, these items tend to get dislodged from their position in the rack of the dishwasher.
If the item is dislodged, it may break. Secondly, if the item is lying on its side, the cup of the stemware may collect a pool of dishwasher water. This pool of water sometimes is dirty. This requires that the stemware be hand washed. Even if the water is not dirty, the stemware must be hand dried. These occurrences decrease the utility of the dishwasher. There is a need for a simple inexpensive device to remedy those deficiencies of a home dishwasher.
A variety of items have been suggested to hold stemware glasses or other unstable items in the appropriate position in the dishwasher while in use. For example, Kauffman, U.S. Pat. No. 3,289,854 discloses a spring-like item to be mounted on an upright rod within a rack of a dishwasher. A glass or similar item is then inserted between the spring-like item and the upright rod in the dishwasher rack. The spring is biased to hold the glassware into a secure position against the upright rod in the dishwasher rack. A similar design is seen in Patera et al., U.S. Pat. No. 4,927,033. The Jacobus et al., U.S. Pat. No. 5,249,590 again uses a spring to provide a biasing pressure against an item to hold it into place. Unlike the Kauffman '854 and Patera '033 patents, in Jacobus et al patent '590 the spring is biased in a downward direction and exerts a downward pressure, rather than a lateral pressure on the item to be held in place.
A slightly different concept is seen in the Mason, U.S. Pat. No. 3,612,285 and the Fiocca et al, U.S. Pat. No. 3,752,322. In both these patents a moveable wire rack assembly folds into place against items to be secured in the top rack of a dishwasher placing an oblique sideways and downward pressure against the items to secure them into place.
A third approach is seen in Peretz, U.S. Pat. No. 4,859,556. There, a free-standing accessory wire rack is secured into position against the bottom rods of the dishwasher. An assembly extends upward a sufficient distance to allow clearance for a stemmed piece of glassware. At the top of the assembly there is a wire mechanism to allow insertion of the stem of the glassware and a downwardly biasing clip to exert pressure against the base of the glassware to hold it into place and suspend it above the bottom support wires in the dishwasher rack. A second embodiment of the Peretz '556 is part of the rack design already present in the dishwasher when purchased, but would otherwise work the same as the first described add-on accessory embodiment.
A very wide variety of general clamping devices are known. These devices have not been used in the application of holding stemware in an upright position in a dishwasher and are far afield from the need this invention is designed to meet. Different types of clamps are widely used to hold together pieces of pipe, wire, cable, and the like. For example, Kramer, U. S. Pat. No. 3,521,332 discloses a double-ended clip that can be used to grip articles in a side-by-side relationship. Wolsh, U. S. Pat. No. 3,228,640 discloses a pipe support clip, which is used to support pipes or conduits to angle iron trusses in buildings that use angle iron trusses to support floors or ceilings. Villacorta, U. S. Pat. No. 4,787,591 discloses a flexible laboratory clamp. This is designed to be used in laboratory applications where a person may have only one hand available to remove or secure an object to the clamp. Virtually every piece of stemmed glassware will have a bowl to hold the liquid and a flat base on which the stemware rests when in use. The specific design parameters of stemmed glassware make it difficult to use a generalized clamp such as disclosed by Villacorta, Wolsh, or Kramer. Insofar as it is possible, it is desirable to hold glassware bowl so that it will directly face the stream of water used in a dishwasher to wash the bowl. The flat base of the stemware means that ordinarily it cannot be secured immediately adjacent to the rack of the dishwasher. Moreover, glassware comes in such a variety of shapes and sizes that provision must be made in a design to not only adjustably fit the different sized stems on glassware, but also to allow variation in the point of attachment along the stem of a glassware to appropriately support glassware in the desirable upright position in the rack of a dishwasher.
Despite the above described patents, none have proven practical in application or are widely adoptable to different designs of dishwashers and dishwasher racks. Consequently, there is still a need for a simple, inexpensive, practical accessory to accomplish the purpose of adjusting to hold different types of stemmed glassware in the correct position during a dishwashing cycle in a home dishwasher.
SUMMARY OF THE INVENTION
The present invention is directed toward a simple one piece accessory designed to support stemmed glassware into an upright position in the rack of a dishwasher. It will work equally well in the top or bottom rack. At one end of the stemware support invention, there is a gripper assembly designed to fit around and grip the stem of glassware. It is designed so that it will grip the stem securely, but not tightly. Stemmed glassware is found in a variety of sizes and shapes ranging from quite small liqueur glasses to quite large beer steins, water goblets, and the like. Thus, the gripper assembly of the stemware support invention adjusts to different diameter stems found in most different types of stemmed glassware.
In a spaced relation from the stemware gripper at the opposite end of the stemware support invention is an attachment device for affixing the stemware support invention to a wire stringer comprising a portion of the rack of a dishwasher. This attachment is designed to easily attach and detach from a wire stringer member of the rack of a dishwasher. It will easily attach to vertical free-standing wire support pieces in the dishwasher or will attach to horizontal wire stringers usually found along the edge of the rack. The attachment to the wire stringer will move up and down on a vertical wire stringer and rotate on a horizontal wire stringer, both movements for vertical adjustment.
When one wishes to affix a stemmed glass in the rack of a dishwasher, one would first find the appropriate space in the rack of the dishwasher, affix the stemware support invention to a wire stringer of the dishwasher rack, then insert the stem of the glassware into the gripper at the opposite end of the stemware support invention from the end which is attached to the dishwasher rack. The stemmed glassware will
