Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention concerns the environment of a kitchen and, more particularly, to a kitchen countertop assembly including multiple planar work surfaces which can be vertically adjusted simultaneously or individually.




2. Discussion of the Prior Art




Although countertop assemblies often found in modern day kitchens provide various vertically offset planar work surfaces, the surfaces are almost invariably fixed at respective, predetermined heights. More specifically, a typical kitchen will include a main countertop work surface and, perhaps, an upper tabletop which is spaced above the main work surface. In the case of a kitchen island, only the main countertop surface is typically provided. In any event, such countertop assemblies are generally fixed at a fairly standard height that is often established by the height of a cabinet base upon which the countertop is supported. Although this countertop height will be fairly standard throughout most residential homes in this country, the height of individuals utilizing the countertops can vary greatly. Therefore, a standard countertop height may not be convenient for shorter individuals, including those in wheelchairs and the like, or rather tall individuals.




Based on the above, there exists a need in the art for a kitchen countertop assembly which can be vertically adjusted to accommodate a wide range of users. More specifically, there exists a need in the art for a versatile countertop assembly incorporating various integrated work surfaces can be vertically adjusted simultaneously or individually in a convenient manner such that the heights of the various work surfaces can be customized to the preference of the user.




SUMMARY OF THE INVENTION




The present invention is directed to a kitchen countertop assembly including multiple, integrated work surfaces which can be vertically adjusted simultaneously or individually in order that the overall countertop assembly can be customized in a convenient manner to suit the particular needs of a user. More specifically, the countertop assembly includes a countertop including a main work surface that is supported above a base in a substantially horizontal plane. Preferably, the main work surface has mounted therein at least one of a sink and a cooktop. Arranged above at least a portion of the main work surface is a tabletop. The tabletop is preferably supported above the main work surface by various vertical legs or pillars which extend through respective openings formed in the countertop. Mounted within the base of the assembly are multiple linear actuators. At least one of the actuators is utilized to selectively, vertically adjust the height of the main work surface and, simultaneously, the height of the tabletop. However, another linear actuator mechanism in the base acts on the support pillars of the tabletop in order to adjust the height of the tabletop relative to the main work surface.




The kitchen countertop assembly also preferably incorporates a table member that can define a small breakfast area or the like. Preferably, the table member projects from and is supported by the base of the overall assembly in a manner which enables the table member to also be vertically adjusted. More specifically, in accordance with the most preferred form of the invention, the table member is vertically repositioned in unison with movement of the main work surface, while also being vertically adjustable relative to the main work surface.




With this overall construction, the various surfaces associated with the kitchen countertop assembly can be conveniently repositioned by a user such that the same countertop assembly can be effectively utilized by a wide range of people having varying height requirements. Preferably, a single control will enable each of the integrated work surfaces to be simultaneously adjusted in height. However, if additional adjustments are desired, the tabletop and/or the table member can be adjusted relative to the main work surface. The integrated work surface arrangement can be advantageously incorporated in an island of a kitchen.




Additional objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment thereof when taken in conjunction with the drawings wherein like reference numerals refer to the corresponding parts in the several views.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




With initial reference to

FIG. 1

, a workstation for a cooking environment that is generally illustrated to take the form of a kitchen island is indicated at


2


. Island


2


includes an overall countertop


6


having a first or main work surface


8


that is preferably provided with a peripheral lip


11


. Also located around first work surface


8


, at a position slightly outwardly and below lip


11


, is railing trim


13


. As shown, countertop


6


also includes a raised platform


16


having a central zone


17


and an associated, intermediate tier


18


. In the embodiment shown, island


2


is provided with a pair of spaced sinks


30


and


31


, as well as a cooking appliance shown in the form of an electric cooktop


34


. For the sake of simplicity of the drawings, a faucet for sinks


30


and


31


, as well as controls for cooktop


34


have not been illustrated. However, cooktop


34


is shown to include multiple, spaced heating elements


35


-


38


. Although the structure and arrangement of cooktop


34


is not considered part of the present invention, cooktop


34


preferably defines a substantially smooth working surface across countertop


6


.




Countertop


6


is shown to be supported by a base


40


having a lowermost section


42


and an upper section


44


that includes an outwardly extending portion


46


. Therefore, upper section


44


, with outwardly extending portion


46


, supports countertop


6


such that first work surface


8


extends in a substantially horizontal plane. At this point, it should be noted that outwardly extending portion


46


need not extend entirely across the longitudinal side of countertop


6


but could simply be constituted by various spaced, cantilevered beams if enhanced leg room or the like is desirable under countertop


6


. In any event, upper section


44


of base


40


is further used to support a table


49


that is adapted to be used in connection with chairs or the like as a small breakfast or other eating area while the portion of countertop


6


located on the opposite side of platform


16


from table


49


would generally be located in the kitchen area. Again, this arrangement is merely presented in accordance with the preferred embodiment of the invention and for the sake of completeness. Island


2


is also shown to include an upper tabletop


51


that is spaced above platform


16


by means of pillars


52


and


53


.




The present invention is particularly directed to the manner in which countertop


6


, table member


49


and tabletop


51


can be selectively, vertically adjusted in unison or relative to each other such that the various work surfaces of island


2


can be placed at varying heights in order to customize the overall assembly to a particular user. More specifically, it is desired in accordance with the present invention to be able to shift countertop


6


vertically to adjust the height of main work surface


8


. At the same time, table


49


and tabletop


51


will shift in unison with countertop


6


. However, the present invention also provides for relative, vertical shifting between table


49


and work surface


8


, as well as between tabletop


51


and work surface


8


of countertop


6


. The preferred structure and arrangement to accomplish these functions in accordance with the present invention will now be particularly described with initial reference to FIG.


2


.




As shown in this figure, island


2


incorporates a first adjusting mechanism


60


which is disposed within base


40


. The first adjusting mechanism


60


is shown to including a pair of spaced linear actuators


62


, each of which includes a cylinder


64


and a piston


66


. Initially, it should be noted that, although two linear actuators


62


are illustrated, a single linear actuator could also be utilized. In addition, although

FIG. 2

illustrates one end of island


2


generally adjacent sink


31


, it should be recognized that a corresponding first adjusting mechanism


60


is provided on an opposing end of island


2


. In any case, as shown, cylinder


64


, at an end opposite piston


66


, is secured to a plate


68


. Plate


68


can either rest on a floor or supporting surface for countertop


6


or be fixedly secured to lowermost section


42


of base


40


. In addition to be slidingly received within cylinder


64


, each piston


66


is also attached to an internal frame member


71


. Internal frame member


71


is secured to upper section


44


of base


40


. In the most preferred form of the invention, each linear actuator


62


of first adjusting mechanism


60


utilizes hydraulic fluid to raise and lower pistons


66


.




As shown in

FIG. 1

, island


2


is provided with a first toggle switch


78


which is used to control first adjusting mechanism


60


for both raising and lowering of each piston


66


. Due to the interconnection of cylinder


64


to lowermost section


42


of base


40


and the connection of piston


66


to upper section


44


of base


40


, the activation of first adjusting mechanism


60


will cause relative vertical shifting between lower and upper sections


42


and


44


and, correspondingly, an adjustment in the height of work surface


8


. The particular range of adjustability accorded by first adjusting mechanism


60


can be readily established by the associated stroke of each linear actuator


62


. However, to be reasonably effective so as to enable island


2


to be adjusted for a fairly wide range of user preferences, an adjustment range in the order of 4-10 inches, and most preferably 6-8 inches is provided. That is, upper section


44


of base


40


can be lowered about lowermost section


42


until upper section


44


almost reaches the support surface for island


2


or work surface


8


can be raised to the position generally illustrated in

FIGS. 1 and 2

.




In further accordance with the present invention, tabletop


51


can be separately adjusted in order to vary the distance between work surface


8


and tabletop


51


. In the most preferred form of the invention, pillars


52


and


53


are vertically shiftable relative to countertop


6


. More specifically, with reference to the right side mounting of tabletop


51


, pillar


53


projects through an elongated opening


80


formed in platform


16


, tier


18


and work surface


8


of countertop


6


. Pillar


53


is supported by a second adjusting mechanism


82


. More specifically, second adjusting mechanism


82


includes one or more linear actuators


84


, each of which is defined by a cylinder


86


and a piston


88


. Each cylinder


86


is shown to be fixed to a cross piece


90


that is secured within base


40


. In the most preferred form of the invention, table


51


is shifted in unison with work surface


8


through first adjusting mechanism


60


. To accomplish this function, cross piece


90


is directly, fixedly secured to either or both of upper section


44


of base


40


and internal frame member


71


. In a manner similar to first adjusting mechanism


60


, linear actuator


84


associated with second adjustment mechanism


82


preferably utilizes hydraulic fluid and the extension and retraction of pistons


88


within cylinders


86


can be controlled through a second toggle switch


93


which is shown adjacent first toggle switch


78


in FIG.


1


. Again, although hydraulic actuators are utilized in accordance with the preferred embodiment, it should be readily apparent that other types of vertical adjustment mechanisms known in the art could be equally employed. For example, pneumatic, electric and the like type mechanisms could be utilized.




In further accordance with the present invention, island


2


incorporates a third adjusting mechanism


95


for use in selectively, vertically adjusting table


49


relative to either of work surface


8


or tabletop


51


. In the most preferred form of the invention as best shown in

FIG. 3

, the third adjusting mechanism


95


preferably includes a plurality of vertically extending rails


97


which are fixedly secured, at laterally spaced intervals, to upper section


44


of base


40


, along with a corresponding number of cantilevered arms


99


upon which table


49


rests. In general, rails


97


and cantilevered arms


99


are of the type commonly found in the art for use in mounting refrigerator shelving or wall shelving. Therefore, although not particularly shown due to the view taken, each rail


97


includes a plurality of vertically spaced slots and each cantilevered arm


99


can be secured to a respective rail at a desired height by extending into a selected set of slots. Actually, third adjusting mechanism


95


can take various forms known in the art without departing from the invention. In fact, arms


99


could be fixedly secured through pistons of additional linear actuators mounted within base


40


and extend through slots formed in upper section


44


such that the vertical adjustment of table


49


could be controlled in a manner directly corresponding to that described above with respect to work surfaces


8


and tabletop


51


. In addition, although rails


97


have been indicated to project along an outer surface of base


40


, rails


97


could be equally embedded in the body of upper section


44


for aesthetic purposes.




With this construction, toggle switch


78


can be utilized to readily raise or lower each of the work surfaces associated with countertop


6


, table


49


and tabletop


51


. In addition, second toggle switch


93


can be utilized to vertically adjust tabletop


51


relative to each of work surface


8


and table


49


. More specifically, tabletop


51


can be shifted from the raised position generally indicated in

FIGS. 1-3

to a lowered position wherein tabletop


51


is set upon platform


16


. Furthermore, table


49


can be vertically adjusted relative to both work surface


8


and table top


51


as desired. Therefore, the overall height of island


2


, as well as the various planar work surfaces associated therewith, can be readily altered to accommodate various users that may range from a person in a wheelchair to a rather tall individual.




Although described with reference to a preferred embodiment of the invention, it should be readily understood that various changes and/or modifications can be made to the invention without departing from the spirit thereof. For instance, although tabletop


51


preferably adjusts in unison with the vertical shifting of work surface


8


, relative shifting could be accomplished through the activation of first adjusting mechanism


60


by simply supporting second adjusting mechanism


82


either on the floor or through lowermost section of base


40


. With such an arrangement, the raising or lowering of work surface


8


would not change the overall height of tabletop


51


, but rather pillars


52


and


53


would simply slide through openings


80


. A similar arrangement could be provided for table


49


if arms


99


project through elongated slots provided in upper section


44


and rails


47


were supported from lowermost section


42


. In any event, in the most preferred embodiment of the invention, table


49


and tabletop


51


shift vertically in unison with work surface


8


of countertop


6


upon the activation of first adjusting mechanism


60


. Regardless, the invention is only intended to be limited by the scope of the following claims.
