Description




BACKGROUND OF THE INVENTION




FIELD OF THE INVENTION




The invention relates to a device for supporting objects for drying. More particularly, this invention relates to an adjustable device that is designed to allow plates, pots, kitchen utensils and silverware to dry.




SUMMARY OF THE INVENTION




The invention relates to a device for supporting objects for drying. This device contains a catch basin, for receiving water that drips off of these drying objects. Attached to the catch basin is a first adjustable rack that is positioned in a substantially horizontal manner. This first adjustable rack has a front end and a back end wherein the back end is rotatably supported within the catch basin. In addition, there is also a second adjustable rack that is rotatably attached to the catch basin and extends in a substantially upright or vertical position. Both the first adjustable rack and the second adjustable rack are comprised of a series of parallel extending bars that are spaced apart from each other to receive a plate between these parallel extending bars or to allow pots to rest thereon. The bars are spaced far enough apart so that they allow water to drip down through the bars and into the catch basin.




In addition, there is an adjustable support bar that is rotatably attached to the substantially horizontal adjustable rack. This adjustable support bar is for rotatably adjusting the height of the front end of the substantially horizontal adjustable rack. Furthermore, disposed within the catch basin is a series of support strips wherein the support strips are designed to support the adjustable support bar in a particular position to keep the adjustable support bar from rotating or sliding when the support bar is supporting the substantially horizontal adjustable rack. The support bar is also useful in that when it is positioned flat, it extends out from the substantially horizontal rack to support extra large pots or pans.




This device is also designed to prevent any water or other materials from flowing onto a counter top outside of the catch basin. For example, the catch basin contains a series of substantially vertical walls to trap this water within the catch basin. In this way, the water will not flow outside of the catch basin and onto a counter top. However, there are at least two drainage holes disposed within the substantially vertical walls to allow a user to easily pour the water disposed within the catch basin out into a sink. In a second embodiment of the invention, a back wall on the basin is curved in to provide additional lateral support for the device.




The device also contains an adjustable tray attached to the catch basin for supporting a series of utensils. The adjustable tray also comprises a set of adjustable legs rotatably attached to the catch basin, a top plate attached to the adjustable legs wherein this top plate has holes for supporting the silverware and utensils in an upright manner. The top plate is adjustable from a folded up position to a folded down position so that the tray can be stored easily.




One of the benefits of this invention is that it can be folded down into a storage position wherein the rack can then be stored away. To facilitate this feature, there is also a catch block disposed within the catch basin wherein this catch block is designed to receive a top end spacer bar on the second adjustable rack to lock the top end spacer bar in place on the catch block. The catch block also contains a slot that is angled in so that it restricts the movement of the spacer bar in the second adjustable rack once the second adjustable rack is snapped in. This second adjustable rack snaps into place over the first adjustable rack so that it locks both racks in place within the catch basin.




Essentially, this device is unique because the first rack in conjunction with the adjustable support bar is designed to create both a dish drying rack and a pot drying rack. When the substantially horizontal rack is supported above a horizontal position, with the adjustable support bar being supported by one of the support strips, the device is designed to support dishes and small to medium sized pots. When the first or substantially horizontal support rack is raised above its horizontal position, this rack gains clearance above the catch basin to receive plates through its parallel extending bars. In addition, with the substantially horizontal rack in this raised position, it creates an angled surface which forces plates to also extend through the second, opposite angled substantially vertical rack. While the device in this position is primarily designed to receive plates, small to medium sized pots can also be placed on the first or substantially horizontal rack for drying.




This device can be adjusted to form a pot drying rack. This pot drying rack is formed when the first or substantially horizontal rack is extended out in a substantially horizontal manner, wherein the support bar is extended out to a series of support elements. When the support bar is extended out, it forms an additional drying surface at substantially the same elevation as the first rack. Because of this additional surface area for drying, this first rack along with the support bar is designed to receive many pots or pans, of small, medium or large size. Now pots with a larger diameter than the width of the first rack can be placed on this first rack and extend out to be supported by this support bar resting on the support elements.




In addition, the utensil rack can be folded down into a substantially horizontal position at an elevation similar to the elevation of this substantially horizontal rack. With this design, the utensil rack in its folded down position, forms an additional pot drying surface which can receive pots that are either placed directly onto the folded down utensil rack, or pots placed onto the first drying rack but hang over this first drying rack.




When the device is in this position, it is a pot drying rack because when the first rack is in its substantially horizontal position, it can no longer support dishes. This is because this first rack is far closer to the bottom of the support basin thereby cutting off a region to receive the plates as they slide through the parallel extending bars. In addition, when the first rack is in this position, it no longer supplies lateral support to the dishes. This lateral support is required to support dishes because the lateral support results in the first rack pushing the dishes into the second, substantially vertical rack.




This device is also unique because it can be tilted up on its end and allowed to stand on a base so that this device can be placed out of the way. This feature occurs because this device contains a unique base that allows this device to stand on one end and because this device is uniquely balanced along a latitudinal axis which extends substantially horizontal when the device is in use on a counter top but extends substantially vertical when the device is tilted up for storage.




The base, which is coupled to the device can be made from any desired shape, but is designed to allow the device to stand up on an end for storage. This base is in the form of but not limited to: a series of legs, a flat back face on the basin, a separate plate connected to the basin, or any other shape to create a support surface on a counter top.




In addition, the design of this device creates a weight balanced device once it is in its compact form. This weight balance allows the device to be free standing on its base so that this device does not need any additional fixtures or support from an adjacent wall or counter surface. For example, once, all three racks: the first rack, the second rack and the utensil rack have been folded down to compact the device, this device is balanced along its latitudinal axis. Now the device can be folded up on its base to be stowed away on a counter top as a free standing device without any support from adjacent walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIG. 1

refers to a perspective view of the invention wherein there is shown a device


10


for drying plates, pots and silverware. Here, there is a first rack


12


rotatably attached to a catch basin


20


, and a second rack


14


rotatably attached to catch basin


20


. Both first rack


12


, and second rack


14


contain a series of parallel extending bars


11


and


13


respectively that are secured at both ends by first and second spacer bars


12


′,


12


″,


14


′, and


14


″ on first and second racks


12


and


14


respectively. These parallel extending bars


11


and


13


are spaced apart to receive a series of plates


15


or at least one pot


17


and also to allow water to drip off of plates


15


, pots


17


and into catch basin


20


. Water can then be drained from catch basin


20


via a drainage hole


23


positioned on a side wall of catch basin


20


.




As shown in

FIG. 2

, the first rack


12


contains a first end bounded by spacer bar


12


′ that is rotatably mounted within catch basin


20


and a second end bounded by spacer bar


12


″ that extends across catch basin


20


. Attached to the second end of first rack


12


is a support bar


16


for supporting the second end of the first rack


12


at different elevations.




The elevation of the second end of the first rack can be set by setting support bar


16


within one of three different support strips


22


,


24


, and


26


designed to receive support bar


16


. These support strips extend parallel across catch basin


20


so that support bar


16


can rest against each support strip to position the second end


12


″ of first rack


12


at varying heights. The support bar


16


is pushed against each support strip by a gravitational force exerted by first rack


12


. In addition, if there are any plates


15


, or pots


17


placed on first rack


12


, this also exerts an additional gravitational force on support bar


16


to further set support bar


16


against one of the support strips


22


,


24


, or


26


.




The elevation of the second end


12


″ of first rack


12


, narrows the distance between first rack


12


and second rack


14


so that different sized plates or pots can fit snugly between parallel extending bars


11


and


13


on first rack


12


and second rack


14


respectively.




In addition, disposed adjacent to first rack


12


and second rack


14


, is a tray


30


designed to support kitchen utensils and silverware


48


in an upright position. In this case, tray


30


consists of a plate


31


that has a series of holes


32


,


33


, and


34


(

FIG. 1

) that are designed to receive these kitchen utensils (not shown) and silverware


48


within, while supporting these objects in an upright manner.




Plate


31


is supported by a series of supporting arms


35


,


36


,


37


, and a fourth arm (not shown) while this plate


31


is held in place by a support arm


39


designed to fix plate


31


in place. In this way, plate


31


provides a support for holding plate


31


in place which holds kitchen utensils or silverware as they are drying.




Disposed below plate


31


is a series of circular containers or storage bins


42


,


44


, and


46


serving as lateral supports for the silverware


48


or utensils, not shown. These containers are designed to receive the utensils


48


to provide lateral support for utensils allowing them to stand in a substantially vertical manner within plate


31


.




Both tray


30


, first rack


12


, second rack


14


and support bar


16


can be folded down so that device


10


can be collapsed into a substantially flat position using a tab


38


as shown in FIG.


3


. Tab


38


is disposed between holes


32


and


33


and extends down from plate


31


so that a user can simply reach his or her fingers into holes


32


and


33


and grip tab


38


to either raise or lower plate


31


. Plate


31


can be positioned in a lowered position as shown in

FIGS. 2 and 5

.




As shown in

FIG. 4

, when rack


12


is folded down into a substantially flat position, support arm


16


extends out so that it is supported on support ridges


25


that lend support to support arm


16


. In this way, support arm


16


forms a substantially horizontal support that extends out beyond first rack


12


to support especially large pots. At this point, the device turns into a pot drying rack for supporting multiple pots or particularly large pots.




As shown in

FIG. 5

, there is also at least one catch block


50


that is disposed within catch basin


20


, wherein as shown in

FIG. 6

, this catch block


50


contains an elevated first end


52


that is designed to receive spacer bar


14


″ of second rack


14


. This spacer bar


14


″ of second rack


14


fits snugly inside catch block


50


so that the device can be folded down in a compact position as shown in FIG.


5


and then tilted up on back wall


21


of catch basin


20


for storage as shown in

FIGS. 8 and 9

.




In addition, there is a longitudinal axis


48


which extends along the longer side of catch basin and also extends parallel to the axes of rotation of racks


12


and


14


as they are folded up or down. Furthermore, there is also shown latitudinal axis


49


which extends along the shorter of the two sides of catch basin


20


and also serves as a midpoint at which the device is weight balanced.




Thus, once racks


12


,


14


, and


30


are folded down, substantially half of the weight of the device is disposed above a plane extending parallel to latitudinal axis


49


, and substantially half of the weight of the device is disposed below this plane. When device


10


is in its substantially flat position, catch basin


20


can be folded up to be free standing upright on wall


21


of catch basin


20


. In this way, once device


10


has been fully collapsed, device


10


only takes up a minimal amount of counter space.




As shown in

FIG. 7

, there is also a mid range support block


60


that is disposed within the catch basin


20


. This support block


60


contains a series of steps


62


and


64


that are designed to support spacer bars


12


′ and


14


′ in a substantially vertical manner. In that way, spacer bars


12


′ and


14


′ do not bend or bow in a middle region due to the weight of pots or plates placed upon racks


12


and


14


.




As shown in

FIGS. 8 and 9

the catch basin


20


can be folded up in a substantially vertical manner wherein the entire device can be positioned in an upright manner so that it can stand freely on a flat surface. The components of device


10


are positioned within catch basin


20


so that when racks


12


,


14


, and tray


30


are collapsed for storage it forms a balanced device along axis


49


that can be supported upright by wall


21


on catch basin


20


. Thus, when the device is tilted up on its edge, with axis


49


extending substantially vertically, this device can remain free standing because the weight of the device in this collapsed position is balanced on either side of axis


49


.





FIG. 10

is a perspective view of the second embodiment of the invention. There is shown a folded down device


110


that is for drying plates, pots, pans and silverware. There is a first rack


112


, that is rotatably attached to a catch basin


120


. In addition, there is a second rack


114


that is also rotatably attached to catch basin


120


. Catch basin


120


differs from catch basin


20


in the first embodiment in that catch basin


120


has rounded edges, and a curved back wall


121


. Curved back wall


121


is designed to catch and retain water inside catch basin


120


. In addition, curved back wall


121


is designed to add additional lateral support due to its curved design. Back wall


121


is curved, so that it provides additional lateral support because this back wall cannot bend along an edge as with a flat back wall.




Both first rack


112


and second rack


114


contain a series of parallel extending bars


111


and


113


respectively. Parallel extending bars


111


and


113


are spaced apart by first and second spacer bars


112





112





114


′ and


114


″ respectively. As in the first embodiment, these parallel extending bars are spaced apart to receive a series of plates or pots while allowing water to drip into basin


120


.




Spacer bars


112


′ and


114


′ are attached at one end in holes


123


and


125


in catch basin


120


respectively, while being attached at an opposite end to a rack support


128


and to a rim


129


on utensil basket


140


(see FIG.


11


). Support rack


128


and rim


129


are designed to have substantially cylindrical recesses that are designed to receive spacer bars


112


′ and


114


′ on racks


112


and


114


respectively.





FIG. 11

shows an exploded perspective view of the second embodiment of the dish rack. Basin


120


has holes


123


and


125


designed to receive racks


112


and


114


. In addition, drainage hole


127


is also shown adjacent to holes


123


and


125


. Catch block


150


and support block


160


can be coupled to basin


120


via a series of screws. These screws are screwed into a series of bosses


156


. Support block


160


consists of an elevated region


162


and a lower region


164


having a hole for allowing a screw to screw into basin


120


.




In addition, support strips


122


,


124


, and


126


are shown extending parallel to each other within basin


120


. These support strips


122


,


124


, and


126


provide support for support bar


116


which supports rack


112


at an angle. For example, support bar


116


can be set into first support strip


122


for a first elevated state, or set into support strip


124


for a second elevated state, or finally into support strip


126


for a third elevated state.




The utensil rack


130


is also shown. This rack


130


consists of a base


140


, a series of arms


135


and


136


and a top plate


131


. Top plate


131


contains a series of open holes designed to allow a user to place a series of utensils within utensil rack


130


.





FIG. 12

shows a cross-sectional front view of the second embodiment of the invention. As shown in this view, catch block


150


is shown as offset from a center region wherein catch block


150


is shown adjacent to rack


130


. In addition, in this view, spacer bars


112


″ and


114


″ are shown wherein spacer bar


114


″ is shown as stacked on top of spacer bar


112


″. Furthermore, spacer bar


114


″ is shown connected snug inside catch block


150


wherein spacer bar


112


″ is locked inside spacer bar


114


″. With this view, the compact design of the second embodiment of the invention is shown wherein both racks


112


,


114


, and


130


are shown folded inside of basin


120


so that it forms a compact balanced design. Thus, this design allows the second embodiment of the invention to stand up on a back edge as shown in

FIGS. 8 and 9

.





FIG. 13

shows a side view of the second embodiment of the invention. With this view, rack


114


is shown fixed inside block


150


wherein legs


152


are shown wrapping around spacer bar


114


″ to hold spacer bar


114


″ inside. Legs


152


extend at an angled rate up from base


152


and are designed to have a protruding point


152


′ to allow spacer bar


114


″ to snap into block


150


. With this view, longitudinal axis


148


, and latitudinal axis


149


are shown. Longitudinal axis


148


extends along substantially parallel to the axes of rotation of racks


112


, and


114


. Latitudinal axis


149


extends substantially perpendicular to longitudinal axis


148


, wherein latitudinal axis


149


extends parallel to a plane that divides the weight evenly above and below the plane to balance the device sufficiently to allow it to stand up on its end. Thus this weight balance of the device creates a free standing device that can be stowed away on a base end when not in use.





FIG. 14

shows a perspective view of rack


130


which is designed as a utensil rack to hold utensils in an upright manner. As shown in this view, rack support


128


and rim


129


are shown having substantially cylindrical recesses designed to receive spacer bars


112


′ and


114


′. There is also a base


140


that has a flange


142


which extends out of base


140


. When rack


130


is moved from its compact position as shown in

FIG. 13

to its upright position shown in

FIG. 14

, top plate


131


is raised up while legs


135


, and


136


rotate within base


140


. As legs


135


rotate up, a cross plate


135


′ snaps over flange


142


. Once cross plage


135


′ snaps over flange


142


, it locks rack


130


in place securing top plate


131


in place.




Essentially, this device is unique because the first rack


12


,


112


in conjunction with the adjustable support bar


16


,


116


are designed to create both a dish drying rack and a pot drying rack. When the substantially horizontal first rack


12


,


112


is supported above a horizontal position, with the adjustable support bar


16


,


116


being supported by one of the support strips


22


,


24


,


26


,


122


,


124


,


126


, the device is designed to support dishes and small to medium sized pots. When the first or substantially horizontal support rack


12


,


112


is raised above its horizontal position, this rack gains clearance above the catch basin


20


,


120


creating an area to receive plates through its parallel extending bars


11


,


111


. In addition, with the substantially horizontal rack


12


,


112


in this raised position, it creates an angled surface which forces plates to also extend through the second opposite angled, substantially vertical rack. While the device in this position is primarily designed to receive plates, small to medium sized pots can also be placed on the first or substantially horizontal rack for drying.




This device can also be adjusted to form a pot drying rack. This pot drying rack is formed when the first or substantially horizontal rack


12


,


112


is extended out in a substantially horizontal manner, wherein the support bar


16


,


116


is extended out to a series of support elements


25


(See FIG.


5


). When the support bar


16


,


116


it is extended out, it forms an additional drying surface at substantially the same elevation as the first rack. Because of this additional surface area for drying, this first rack along with the support bar is designed to receive many pots or pans, of small, medium or large size. Now pots with a larger diameter than the width of the first rack can be placed on this first rack and extend out to be supported by this support bar resting on the support elements


25


.




In addition, utensil rack


30


,


130


can be folded down into a substantially horizontal position at an elevation similar to the elevation of this substantially horizontal rack


12


,


112


. With this design, the utensil rack


30


,


130


in its folded down position forms an additional pot drying surface which can receive pots that are either placed directly onto the folded down utensil rack or pots placed onto the first drying rack but hang over this first drying rack.




When the device is in this position it is a pot drying rack because when the first rack


12


,


112


is in its substantially horizontal position, it can no longer support dishes. This is because this first rack


12


,


112


is far closer to the bottom of the support basin


20


,


120


thereby cutting off a region to allow the plates to slide through the parallel extending bars. In addition, when the first rack


12


,


112


is in this position, it no longer supplies lateral support to the dishes. This lateral support is required to support dishes because the lateral support results in the first rack


12


,


112


pushing the dishes into the second, substantially vertical rack


14


,


114


keeping the dishes from falling over.




This device is also unique because it can be tilted up on its end and allowed to stand on a base so that this device can be placed out of the way. This feature occurs because this device contains a unique base that allows this device to stand on its end and because this device is uniquely balanced along a latitudinal axis which extends substantially horizontal when the device is in use on a counter-top but extends substantially vertical when the device is tilted up for storage.




The base, which connects to the device can be made from any desired shape, but is designed to allow the device to stand up on an end for storage. This base is in the form of but not limited to: a flat back face


21


, extending along a latitudinal axis


48


, series of legs


121


′ spaced apart by a curved back face


121


extending along a latitudinal axis


148


, a separate plate connected to the basin (not shown), or any other shape to create a support surface on a counter top.




In addition, the design of this device creates a weight balanced device once it is in its compact form. This weight balance allows the device to be free standing on its base so that this device does not need any additional fixtures or support from an adjacent wall or counter surface. For example, once all three racks: the first rack


12


,


112


, second rack
