Abstract
An apparatus having one or two steps at the election of a user. The apparatus is stored under a counter in a space that is normally wasted. When in its single step configuration the apparatus has a generally parallelepiped appearance and includes a transversely disposed front wall, longitudinally extending side walls, a transversely disposed rear wall, and a top wall that provides a first step. A folding line formed in the top wall enables a trailing section of the structure to be rotated until the rear wall lies in a horizontal plane and provides a second step. A transverse rod facilitates rotation of the second step and the transverse rod supports the second step after it has been deployed. The rod has a telescoped construction and permits lowering of the second step when the user exerts an axial force against the rod.
Description




BACKGROUND OF INVENTION




1. Field of the Invention




This invention relates, generally, to auxiliary steps. More particularly, it relates to an auxiliary step means that is storable beneath a cabinet when not in use.




2. Description of the Prior Art




Many kitchen cabinets are positioned at heights that are unreachable by many people. Small step ladder-like platforms can be used to reach high cabinets, but such ladders occupy storage space when not in use and thus add to the clutter of a household.




Inventors have responded to the problem by developing step structures that are stored under or in kitchen counters. Those that are stored in the counters occupy storage space and thus have less value relative to those that are stored under a counter in an otherwise unused space.




Typically, the step structures provide a single step that may help some people reach the cabinets, but for many people a single step is not enough. There are some step structures that provide two steps, but some people do not require a second step.




What is needed, then, is a step structure that provides a single step to those who require just a single step, and that provides a second step when needed by those who require a second step.




However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.




SUMMARY OF INVENTION




The longstanding but heretofore unfulfilled need for an apparatus that brings elevated kitchen cabinets within reach is now met by a new, useful, and nonobvious invention that enables a user to deploy a single step or a double step as needed.




The novel auxiliary step means of this invention is adapted to be stored in a space under a counter. The structure includes a transversely disposed, vertical front wall and a transversely disposed, vertical rear wall positioned in parallel, longitudinally spaced apart relation to the vertical front wall. The vertical rear wall has a transverse extent equal to a transverse extent of the vertical front wall.




A pair of longitudinally extending, transversely spaced apart vertical side walls have leading ends secured to opposite ends of the vertical front wall. A horizontally disposed top wall has a longitudinal extent substantially equal to a longitudinal extent of the vertical side walls and has a transverse extent substantially equal to the common transverse extent of the vertical front and rear walls.




A transversely disposed folding line is formed in the top wall and divides the top wall into a leading section and a trailing section. A rotating means is provided for rotating the trailing section about the folding line until the trailing section is disposed normal to the leading section and the vertical rear wall is disposed in a horizontal plane. A support means is provided for supporting the vertical rear wall in said horizontal plane. The horizontally disposed top wall provides a first step when the auxiliary step means is deployed and the vertical rear wall provides a second step when disposed in said horizontal plane.




A first, longitudinally extending, vertical brace wall has an upper edge secured to a first edge of the trailing section of the top wall and a trailing edge secured to a first edge of the vertical rear wall. A second, longitudinally extending, vertical brace wall has an upper edge secured to a second edge of the trailing section of the top wall and a trailing edge secured to a second edge of the vertical rear wall. The first and second brace walls maintain the vertical rear wall in normal relation to the trailing section of the top wall. The first brace wall has a free leading edge in substantial alignment with an imaginary vertical plane that passes through the folding line and the second brace wall also has a free leading edge in substantial alignment with said imaginary vertical plane.




The rotating means includes an arcuate slot formed in a preselected one of the vertical side walls. The arcuate slot has a lowermost end formed in the preselected vertical side wall at a preselected point therein in substantial alignment with the imaginary vertical plane. The arcuate slot has an uppermost end in open communication with an upper edge of the preselected vertical side wall. A transversely disposed rod has opposite ends that extend through the first and second vertical brace walls at preselected apertures formed in a lower, leading corner of each of the vertical brace walls in substantial alignment with the imaginary vertical plane. The apertures are in axial alignment with the lowermost end of the arcuate slot when the leading and trailing sections of the top wall are in coplanar relation to one another. The rod has a length greater than the transverse extent of the front and rear vertical walls. It therefore extends transversely beyond the preselected vertical side wall a predetermined distance so that a free end thereof is adapted to be engaged by a user. Lifting the free end of the rod rotates the trailing end of the top wall about the folding line.




A gate means is pivotally mounted to a top edge of the preselected vertical side wall. It spans the uppermost end of the arcuate slot when the gate means is in repose and is momentarily pivotally opened when the user lifts the rod to a preselected height above the top edge of the preselected vertical wall. The gates means closes behind the rod so that when the rod is released by the user, the gate means supports the rod and prevents it from re-entering the arcuate slot, thereby maintaining the rear vertical wall in its horizontal, second step-providing position.




The space under the counter is enclosed at least in part by a front skirt and a back skirt. An opening is formed in the front skirt to slideably receive the auxiliary step means. A pair of laterally outwardly extending flanges is secured to the vertical front wall and a first magnet means is secured to a trailing side of said flanges. A second magnet means is secured to the front skirt on opposite sides of the opening formed therein. The first magnet means releasably engages the second magnet means when the auxiliary step means is stored within the space under the counter. A bias means is mounted on a leading side of the back skirt; it is under compression when the auxiliary step means is stored within the space under said counter. The bias means is adapted to exert a force that is slightly insufficient to separate the first and second magnet means from one another when the bias means is in a state of repose. When momentarily compressed and released, the bias means generates a force sufficient to separate the first and second magnet means from one another. A user may momentarily cause compression of the bias means by kicking the front wall.




A primary object of the invention is to provide an apparatus that enables people to reach kitchen cabinets, or the like, that are mounted above kitchen or other counter tops.




Another object is to provide such an apparatus that is storable in an unused space beneath a counter.




Another important object is to provide an apparatus that deploys either one or two steps depending upon the requirements of a user.




Still another object is to provide an apparatus that is easily deployed by a user and just as easily returned to its storage configuration.




These and other important objects, advantages, and features of the invention will become clear as this description proceeds.




The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the description set forth hereinafter and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION




Referring now to

FIG. 1

, it will there be seen that the reference numeral


10


denotes a typical environment within which the novel structure is used.




Although the invention may be used in any room of a house or other structure, it is primarily intended for use in a household kitchen. Kitchen


10


includes a counter


12


having a bottom wall


14


and a normally wasted space


16


therebelow. Front skirt


16




a


and back skirt


16




b


(

FIGS. 8 and 9

) enclose the front and back of said space


16


. Cabinets


18


(

FIG. 1

) are positioned in elevated relation to counter


12


and can be out of reach for many people standing on floor


20


of the kitchen.




Advantageously, novel auxiliary step means


21


is storable within space


16


and is deployable therefrom in drawer-like fashion, there being a suitable opening formed in front skirt


16




a


to accommodate said auxiliary step means. In

FIG. 1

, auxiliary step means


21


is depicted in its deployed, extended configuration.




More particularly, auxiliary step means


21


includes first step


22


and second step


24


that is deployable into the configuration depicted in FIG.


1


. The novel structure forms a hollow parallelepiped structure when second step


24


is in its stored, undeployed configuration, as perhaps best understood from an inspection of FIG.


8


.





FIG. 2

provides a front elevational view of counter


12


, bottom wall


14


of said counter, and of first step


22


and second step


24


when in their respective deployed configurations.




Auxiliary step means


21


includes a transversely disposed, vertical front wall


30


(FIG.


2


), longitudinally extending vertical side walls


32


,


34


, (FIG.


3


), horizontally-disposed top wall


36


and transversely disposed, vertical rear wall


38


. In

FIG. 3

, vertical rear wall


38


is depicted in it deployed configuration where it serves as the tread or support surface for second step


24


. Rear wall


38


is vertically disposed when second step


24


is in its stored configuration as depicted in

FIGS. 7 and 8

.




Arcuate slot


40


is formed in side wall


34


near its trailing end. Slot


40


is in open communication with top edge


42


of side wall


34


.




A gate means


44


is pivotally mounted as at


46


to said side wall


34


and has a position of repose, depicted in

FIG. 3

, where it spans the uppermost end of arcuate slot


40


and rests atop said top edge


42


on the opposite side of said slot


40


relative to pivot point


46


.




A transversely disposed folding line


50


, depicted as a hinge means; is formed in top wall


36


and divides said top wall into leading section


52


and trailing section


54


(see FIG.


7


). The opposed, longitudinally extending edges of leading section


52


are secured to or integrally formed with top edges


41


,


42


of sidewalls


32


,


34


, respectively. Accordingly, leading section


52


of top wall


36


provides the first step


22


of auxiliary step means


21


. The opposed, longitudinally extending edges of trailing section


54


, however, are not secured to said top edges of said side walls. This enables second step


24


to be rotated from its stored configuration (

FIGS. 7 and 8

) into its deployed configuration (all other Figs.).




A pair of brace walls


58


,


60


are positioned at opposite ends of vertical rear wall


38


, in leading relation thereto. Brace wall


58


has a first edge secured to trailing section


54


of top wall


36


, a second edge secured to vertical rear wall


38


, and two unconnected edges


57


,


59


(FIG.


3


). The height of brace wall


58


is substantially equal to that of side walls


32


,


34


and the longitudinal extent of said brace wall is equal to the longitudinal extent of second section


54


of top wall


36


. Brace wall


60


has the same construction as brace wall


58


, having a first edge secured to trailing section


54


, a second edge secured to vertical rear wall


38


, and two unconnected edges denoted


61


and


63


(FIGS.


3


and


7


).




An elongate, transversely disposed rod


70


having two sections


72


,


74


joined by housing


76


extends through apertures formed in brace walls


58


,


60


at their respective lower, leading corners as depicted in

FIGS. 3

,


4


, and


5


. Rod


70


has a telescoping construction and is biased by means contained in housing


76


so that it is fully extended when in repose (FIGS.


3


and


4


). When fully extended, a first end or extension


78


thereof extends through arcuate slot


40


and rests atop the lowermost end of said slot when second step


24


is not deployed, as depicted in FIG.


7


. The length of rod


70


is preselected so that said first end or extension


78


thereof protrudes beyond the plane of side wall


34


(FIGS.


3


and


4


), said extension


78


providing a handle means for rotating second step


24


about hinge


50


. Thus, when first step


22


is deployed into its operable configuration, if a second step is needed the user lifts extension or handle means


78


with the toe of a foot and raises it upwardly so that rod


70


travels along the extent of arcuate slot


40


from its lowermost position (FIG.


7


). Such lifting continues until gate means


44


is pivoted by said rod


70


about pivot point


46


and lifted upwardly as also indicated in

FIG. 7

so that rod


70


can completely exit arcuate slot


40


and travel above top edge


42


of side wall


34


. Gate means


44


is sized such that when rod


70


has completely exited arcuate slot


40


, the gate means falls back under the influence of gravity into its position of repose where it spans the uppermost opening of said arcuate slot, thereby preventing re-entry of rod


70


into slot


40


when said rod is released. The user lowers rod


70


until said rod is supported by said closed gate means as depicted in

FIGS. 1

,


3


,


4


,


6


, and


9


. This positions second step


24


into its operative, deployed configuration as depicted in said Figs. Note that trailing section


54


of top wall


36


is in a vertical plane when second step


24


is deployed and that vertical rear wall


38


is in a horizontal plane and serves as the support surface for the second step


22


as mentioned earlier.




It should also be observed that the lowermost end of arcuate slot


40


is spaced slightly to the trailing side of an imaginary vertical plane that passes through hinge


50


.




To lower second step


24


into its stored configuration so that novel assembly


21


can be stored in storage space


16


as depicted in

FIG. 8

, gate means


44


may be lifted to grant rod


70


access to arcuate slot


40


. Alternatively, the user may press against rod


70


in an axial direction as indicated by single-headed directional arrow


79


in FIG.


4


. When extension


78


of rod part


74


is pressed, it retracts. Simultaneously, rod part


72


also retracts, due to a mechanism, not shown, positioned within housing


76


. Mechanisms that cause two rods to retract axially when only one of them is actively urged to retract are known and form no part of this invention, per se. When extension


78


is fully retracted, it clears gate. means


44


so that second step


24


is no longer supported by rod


70


. Upon being released, the bias means in housing


76


again urges parts


72


and


74


of rod


70


to diverge from one another in opposite axial directions and extension


78


again enters into slot


40


and guides second step


24


into its fully folded, stored configuration.




Depending on the amount of space between kitchen floor


20


and counter bottom wall


14


, first step


22


can be about six inches in height. Thus, when deployed, first step


22


may provide sufficient height to enable a user to reach an upper cabinet


18


when standing thereatop.




Second step


24


is deployed only if first step


22


provides inadequate elevation.




Note spring


90


in

FIGS. 9 and 10

. There are two of such springs; the second spring is behind spring


90


in said Figs. Said springs


90


are compressed by laterally-extending flanges


96


,


98


(

FIGS. 3-5

) when auxiliary step means


21


is in its stored position (see FIG.


8


).




As best depicted in

FIGS. 3 and 10

, another pair of laterally-extending flanges


92


,


94


, are formed in front wall


30


. A first magnet means


92




a


(

FIG. 3

) is secured to flange


92


near its upper end and a second magnet means, not shown, is secured to said flange


92


near its lower end. Similarly, magnet means


94




a


,


94




b


(

FIG. 3

) are secured to flange


94


on the trailing side thereof. As indicated in

FIG. 10

, a first pair of magnet means (not shown) are secured to front skirt


16




a


on a first side of the opening formed in said front skirt and a second pair of magnet means


94




c


,


94




d


are secured to said front skirt


16




a


on a second side of the opening formed in said front skirt to receive auxiliary step means


21


. The term “magnet means” includes a magnet and any suitable ferrous material. Thus, magnets can be attached to flanges


92


,


94


and ferrous material to front skirt


16




a


, or vice versa. Accordingly, a user may simply lightly kick front wall


30


, which may be provided with a suitable kick plate that overlies front wall


30


, thereby momentarily compressing springs


90


. When said springs recover from such momentary compression, their expansion separates the engaged magnet means from one another so that the user may then pull auxiliary step means


21


from storage space


16


in the same way a drawer is opened.




There are numerous mechanisms that can accomplish the above-described locking of second step


24


in its stored and deployed configurations, and all structures equivalent to the structure depicted and described herein are within the contemplation of this invention. The same observation applies to the magnets and spring mechanism and to the other mechanical parts of the invention. For example, hinge


50


may be provided in the form of a living hinge, thereby eliminating hardware


50


.




It will thus be seen that the objects set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.




It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
