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.
Now that the invention has been described,
