Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application No. 62/349,969 entitled "MESS-FREE SAND PLAY DEVICE,"
filed Jun. 14, 2016, having Attorney Docket Number HALC.246839, the
entire contents of which is hereby incorporated by reference.
SUMMARY
[0002] Aspects of the disclosure are defined by the claims below,
not this summary. A high-level overview of various features are
provided here for that reason, to provide an overview of the
disclosure, and to introduce a selection of concepts that are
further described in the detailed description section below. This
summary is not intended to identify key features or essential
features of the claimed subject matter, nor is it intended to be
used as an aid in isolation to determine the scope of the claimed
subject matter.
[0003] This disclosure describes, among other things, devices and
methods for sand play. In particular, one aspect of the disclosure
is directed to a mess-free sand play device including an apparatus
for containing a predefined amount of loose, granular sand in a
completely sealed container. The apparatus for enclosing loose,
granular sand comprises a tray having a planar base and an
upstanding wall rising from a perimeter of the planar base and a
cover coupled to the tray to seal the loose, granular sand within a
cavity formed by the coupled tray and cover. The cover may be
constructed with a clear window so that the loose, granular sand
and the tray are visible through the clear window. Alternatively,
the entire cover and/or tray may be clear or transparent so that
all internal features of the mess-free sand play device are made
visible from above, and/or other angles of the mess-free sand play
device.
[0004] In a further aspect herein, in addition to the loose,
granular sand, a moveable device or internal stylus is located
within the cavity enclosed by the tray and the cover. The moveable
device or internal stylus is configured to form temporary patterns
in the loose, granular sand when dragged through the loose,
granular sand by an external stylus located outside of the cavity.
In some aspects, the moveable device or internal stylus comprises a
foam tip and a magnet, wherein the foam tip and the magnet may be
secured within a housing. The housing securing the foam tip and the
magnet may include a feature for securing the foam tip in relation
to the magnet, such as a rod fitted through the foam tip to secure
the foam tip to the housing and a magnet housing cavity configured
to enclose one or more magnets within the magnet housing cavity.
The housing may be constructed in multiple parts that can be fitted
together and/or welded together once the foam tip and the one or
more magnets are secured into place, or the housing may be
manufactured in a single piece over the one or more magnets with a
mechanism to secure the foam tip. In some aspects, the moveable
device or internal stylus includes a marking end, such as the foam
tip that generates markings in the loose sand, and a directing end,
such as the magnetic end of the internal stylus that is manipulated
by an external source to provide translation of the internal stylus
inside the cavity and with respect to the tray.
[0005] Further, the magnets of the moveable device or internal
stylus may additionally be enveloped by a soft, non-conducting
material such as an inherently anti-static fabric or a material
treated with an anti-static coating. Alternatively, the one or more
magnets may be covered by, for example, with a looped textile
material such as the one used in a hook-and-loop fastening system.
The moveable device or internal stylus may be configured to stand
in a generally upright position, with the foam tip pointing
downward and in contact with the loose, granular sand, and with the
one or more magnets opposite the foam tip, pointing upward and near
the cover and/or the clear window. As such, the internal stylus may
have a minimum height that corresponds to the height of the cavity,
thus orienting the internal stylus with the marking end adjacent
the tray and the magnetic end adjacent the cover.
[0006] The loose, granular sand may be any moveable and/or
deformable material enclosed within the cavity and responsive to
force applied by the moveable device or internal stylus, such as a
loose material having properties of that from fine to coarse sand.
Additionally, the color of the loose, granular sand may be natural,
white, black, blue, purple, pink, or any other color available. In
accordance with aspects herein, the sand may, for example, be
coarse white sand that reflects at least a portion of light to
which the sand is exposed. In some aspects, the granular sand may
be any particulate and/or granular medium that is moveable by the
internal stylus, and in response to movement by the marking end
(i.e., foam tip) of the internal stylus, may be shifted around on
the surface of the tray. In some aspects, the "markings" on the
tray are generated based on a revealed portion of the tray surface,
such as a blue tray surface that is covered by white sand, once the
white sand is pushed away along a travel path of the internal
stylus, and the revealed blue tray portions become a visible,
"hand-drawn" design.
[0007] In accordance with aspects herein, a lighting component such
as a color light fixture may be provided within the mess-free sand
play device. The lighting component may be strategically placed
above the loose, granular sand to reflect light onto the loose,
granular sand and an interior surface of the tray. As such, a
user's markings within the cavity and into at least a portion of
the loose, granular sand using the internal stylus may provide a
different light pattern than the surrounding sand, thereby
illuminating the remaining sand around the sand drawing. The
lighting component may be configured to cycle through at least one
light color at a time. The lighting component may be configured to
cycle through a particular number of light colors, such as, for
example, three visible light colors, six visible light colors, nine
visible light colors, twelve visible light colors, fifteen visible
light colors, eighteen visible light colors, twenty-four visible
light colors, thirty-six visible light colors, forty eight visible
light colors, one hundred visible light colors, etc. The visible
light colors of the lighting component may be configured to cycle
automatically through a number of color light patterns at a
predefined time interval, or may be configured to cycle manually
via a switch provided on an exterior surface of the mess-free sand
play device. An advantage of having loose, granular white sand in
the mess-free sand play device is that when colored light is shone
on the loose, granular white sand, the white sand is able to
reflect the true color of the colored light, making at least a
portion of the white sand appear to be the color of the light shone
onto it.
[0008] In accordance to further aspects herein, the lighting
component of the mess-free sand play device may be battery operated
and/or electricity operated via an electric plug. At least one
battery may be securely stowed away within the cavity for safety.
The at least one battery required may be disposable or
rechargeable. In the event that the at least one battery is
rechargeable, the at least one battery may be made inaccessible or
accessible with safety precautions. Further, the at least one
battery may be allowed to charge within the mess-free sand play
device when the mess-free sand play device is plugged into an
electrical outlet.
[0009] The quantity of loose, granular sand contained within the
mess-free sand play device may be dependent on the dimensions of
the mess-free sand play device. For example, enough loose, granular
sand to cover an interior surface of the tray at a particular depth
when the loose, granular sand is evenly spread out, without
weighing down the mess-free sand play device, may be provided. For
example, if determined that 0.5 grams of loose, granular sand per
square centimeter (area) of the interior surface of the tray be
provided to achieve good coverage, in the event that the total area
of the interior, planar surface of the tray is measured to be 25
cm.times.15 cm=375 cm.sup.2, this would require approximately 187.5
grams of loose, granular sand. Additionally, it can be appreciated
that the amount of loose, granular sand needed may also be affected
by the loose, granular sand coarseness, and as such, the amount of
loose, granular sand may be determined based on the properties of
the sand and/or the dimensions of the mess-free sand play device.
Another factor that may affect an amount of loose, granular sand
needed may include, for example, a weight limit for the mess-free
sand play device. For example, depending on a target age group, the
dimensions of the mess-free sand play device and the weight
limitations of the mess-free sand play device may be changed.
[0010] Moving on to features that are external to the mess-free
sand play device, the mess-free sand play device may comprise a
magnetic stylus/external stylus configured to engage with the
moveable device or internal stylus that resides within the
mess-free sand play device. As described above, the moveable device
or internal stylus within the mess-free sand play device comprises
a magnetic top. The external magnetic stylus comprises a magnetic
tip configured to interact with the internal stylus for
manipulating a location of the internal stylus within the cavity.
The markings imprinted in the sand by the internal stylus may
therefore be directed by the movement of the external magnetic
stylus manipulating the internal stylus. Based on fluid motion of
the internal stylus within the cavity, multidirectional translation
of the internal stylus may be facilitated by the external magnetic
stylus, thereby "dragging" the internal stylus to one of a number
of locations within the mess free sand play device.
[0011] The magnetic tip of the external magnetic stylus may be
inaccessible to a user, such as by being secured internally to the
external magnetic stylus by one or more mechanisms, for safety and
aesthetics. Additionally, the external magnetic stylus may be made
in any desired shape, such as, for example, an elongated cylinder
like a pen, a sphere like a rounded ball, or a pear-shape having a
tapering end, with the magnet being located at the tapering end.
The pear-shape may be, for example, an ergonomic shape configured
to comfortably fit within the hand and fingers of an operator or
user. In particular, depending on the age of the target user, the
size of the target user, and the target user's motor ability, the
stylus may be made smaller or bigger. For example, the pear-shaped
stylus may be configured to comfortably fit within the hand of an
eighteen month or older toddler, a twenty-four month or older
toddler, a toddler between the ages two and five, etc.
[0012] The mess-free sand play device may further comprise a
magnetic storage base for storage of the magnetic external stylus
when the magnetic external stylus is not in use. In aspects, the
magnets used in the moveable device or internal stylus, the
magnetic external stylus, and the magnetic storage base are
permanent magnets with distinct North and South poles. These
magnets may be made as disks, sheets, or any shape configured to be
safely retained within their intended locations. The magnets may be
made of any type of magnetizable material such as metal. Further,
where one feature of the sand play device may include a magnet
component, the corresponding feature that interacts with such
feature may include a metallic component to which the magnetic
component is attracted. The magnets in accordance with aspects
herein may be strong enough to attract each other through one or
more layers of material, wherein the layers of material may
comprise, for example, fabric, plastic, polycarbonate, tempered
glass, etc. The magnets may be further strong enough to pull each
other even when an air gap is present between them. For example, an
amount of space between the internal stylus and the external stylus
may be impacted by a material thickness, fabric thickness, base
thickness, window thickness, air-gap thickness, and the like,
without interrupting the drawing capabilities inside the sand of
the sand play device.
[0013] As such, the mess-free sand play device, in accordance with
aspects herein, allows for creative sand play and sand doodling by
providing a completely enclosed amount of loose, granular sand and
a moveable device or internal stylus within the enclosure of a
mess-free sand play device, wherein the moveable device or internal
stylus is able to be manipulated via an external magnetic stylus,
and wherein the magnetic stylus is configured to pull the moveable
device or internal stylus at will, within the confinements of the
cavity of the mess-free sand play device.

DETAILED DESCRIPTION
[0024] The subject matter of select embodiments of the invention is
described with specificity herein to meet statutory requirements.
But the description itself is not intended to necessarily limit the
scope of claims. Rather, the claimed subject matter might be
embodied in other ways to include different components, steps, or
combinations thereof similar to the ones described in this
document, in conjunction with other present or future technologies.
Terms should not be interpreted as implying any particular order
among or between various steps herein disclosed unless and except
when the order of individual steps is explicitly described.
[0025] Devices and methods are described herein for mess-free sand
play. In particular, one aspect of the disclosure is directed to a
device including a tray coupled to a cover enclosing a
predetermined amount of non-magnetic loose, granular sand and at
least a moveable device or internal stylus. The moveable device or
internal stylus comprises a closed cell foam tip and a magnetic
top. The moveable device or internal stylus is movable through the
sand via an external stylus comprising a magnetic tip. The magnetic
top of the moveable device or internal stylus and the magnetic tip
of the external stylus are configured to attract each other so that
the moveable device or internal stylus is able to be dragged
through the loose, granular sand within the confines of the
mess-free sand play device. As the moveable device or internal
stylus is moved around through the sand, the moveable device or
internal stylus is configured to leave a track in the sand, behind
its travel path.
[0026] In a further aspect, the mess-free sand play device further
comprises at least one lighting component configured to expose the
enclosed sand to an amount of light, such as a color lighting
component configured to shine a colored light onto the loose,
granular sand so that the loose, granular sand appears illuminated
and/or colored, such as having the appearance of the color of light
shone onto it. In some aspects, the lighting component dispenses
light into the cavity in a particular direction, such as at an
angle towards the surface of the enclosed sand. The lighting
component may be battery operated and/or electricity operated, and
may further be configured to include multiple visible colors. In
accordance with aspects herein, a switch may be provided to
manually and/or automatically cycle through the multiple visible
colors of the lighting component. By illuminating the sand
surrounding a path that is cleared of sand by the internal stylus,
the areas of displaced sand and revealed tray are emphasized
markings surrounded by the lit sand within an enclosed drawing
environment, in aspects of the invention.
[0027] With reference now to the figures, a mess-free sand play
device is described in accordance with aspects herein. Various
aspects are described with respect to the figures in which like
elements are depicted with like reference numerals.
[0028] With reference to FIGS. 1-7, an exemplary mess-free sand
play device 100 is shown. In FIG. 1, the exemplary mess-free sand
play device 100 includes a tray 12 coupled to a cover 14 with a
clear window 16, forming a cavity 94. The tray 12 comprises an
upstanding wall rising from a perimeter of tray 12, the upstanding
wall comprising a wall interior 18 and a wall exterior 44. There is
also optionally provided at least one lighting component 20 located
within the cavity 94 near a top end of the upstanding wall, above
the loose, granular sand level, to reflect light onto the loose,
granular sand 46. The at least one lighting component 20 may be,
for example, an LED lighting component comprising one or more
visible colors. The at least one lighting component 20 may, for
example, comprise three visible colors, six visible colors, ten
visible colors, twelve visible colors, twenty-four visible colors,
or any number of visible colors desired. When more than one
lighting component 20 is provided, each lighting component 20 may
operate simultaneously with the other, shining the same color at
the same time, or simultaneously with the other, shining different
visible colors at the same time to form new visible colors by
virtue of the mixing of the reflection of the shone light visible
colors. The visible colors of the light may be automatically
changed and/or may be manually changed by actuating a switch 40,
also provided on an exterior surface of the mess-free sand play
device 100.
[0029] The mess-free sand play device 100 may further comprise a
moveable device or internal stylus 28. The moveable device or
internal stylus 28 may comprise a foam tip 30 and a magnet encased
within magnet housing 32. As shown in FIG. 1, the moveable device
or internal stylus 28, the loose, granular sand 46, and the
lighting component 20 may all be enclosed within tray 12 and cover
14. Further, although not shown, the moveable device or internal
stylus 28 may further include a magnet 52 (shown in FIGS. 5A-5B and
FIG. 7) within a dock 24 and internal to the cover 14. Furthermore,
the mess-free sand play device 100 may comprise an external stylus
26 with a magnetic tip 42. The external stylus 26 may be optionally
tethered to the mess-free sand play device 100 via tether 22, which
is attached to the mess-free sand play device 100 at a first tether
outlet 36, and which is attached to the external stylus 26 at a
second tether outlet 34. When not in use, the dock 24 is configured
to receive the external stylus 26, and if magnetized, the dock 24
is configured to securely hold the external stylus 26 in place and
guide a user to the storage location by magnetically pulling the
external stylus 26 into the dock 24 when the external stylus 26 is
in the vicinity of the dock 24. Additionally, the mess-free sand
play device 100 may be designed to comprise a carrying handle 38,
which may be ergonomically shaped to be easily carried by, for
example, a small toddler.
[0030] Moving on to FIG. 2A, a perspective view of the mess-free
sand play device 100 of FIG. 1, with the tether 22 removed from
view, includes a mess-free sand play device 100 in a rest/store
position in accordance with aspects herein. As it can be observed
from FIG. 2A, the external stylus 26 is configured to fit within
the dock 24. Further, it can be observed that the moveable device
or internal stylus 28 is configured to remain in a generally
upright position within the cavity 94, with the foam tip 30
pointing downward toward the tray 12 and the magnet within magnet
housing 32 pointing upward toward the clear window 16. As described
above, the magnet inside the magnet housing 32 may be covered by a
soft material such as a woven or non-woven fabric to provide a
buffer between the magnet and the interior surface of clear window
16 and thereby prevent scratching of the interior surface of clear
window 16 as the moveable device or internal stylus 28 is moved
around.
[0031] FIG. 2B shows a perspective view of the mess-free sand play
device 100 of FIG. 2A, in an active/use position in accordance with
aspects herein. As it can be observed in FIG. 2B, the external
stylus 26 magnetically engages with moveable device or internal
stylus 28 and is configured to pull moveable device or internal
stylus 28 through the loose, granular sand 46 within the confines
of the cavity 94. As the moveable device or internal stylus 28 is
moved through the loose, granular sand 46, the foam tip 30 forms a
path 10 in the spread out loose, granular sand 46. In accordance
with aspects herein, the path 10 comprises a path of exposed tray
void of sand. When light is shone onto the path 10, the path of
exposed tray void of sand appears darker in appearance than parts
of the path covered by the loose, granular sand 46. The path 10 may
be easily removed from the sand by gently shaking the mess-free
sand play device 100 to redistribute the loose, granular sand 46.
Once shaken, the mess-free sand play device 100 is reset and again
ready for forming new paths 10 in the loose, granular sand 46. In
accordance with aspects herein, the loose, granular sand 46
comprises a non-magnetic material.
[0032] Moving on to FIG. 3, FIG. 3 is a cross-sectional view along
the plane passing through the line 3-3 in FIG. 2B in accordance
with aspects herein. As it can be clearly observed from FIG. 3,
foam tip 30 of moveable device or internal stylus 28 may not be
perfectly perpendicular to the planar surface of tray 12, but
rather, it is slightly angled, deviating between about 1 and 10
degrees from perpendicular. This slightly angled configuration for
the foam tip 30 may allow the moveable device or internal stylus 28
to easily glide through the loose, granular sand 46 and be less
prone to getting stuck or caught within the cavity 94, thereby
making the process of doodling in the loose, granular sand 46 a
smooth process. Further, the angled configuration of the foam tip
30 allows for the loose, granular sand 46 to fall back into the
path 10 at an inward angle, as the foam tip 30 is pulled through
the loose, granular sand 46, thereby creating the impression of
outlines for the path 10.
[0033] As it can be further observed from FIG. 3, the lighting
component 20 may be located near the top of the mess-free sand play
device 100, such as near the cover 14. This configuration allows,
in some aspects, for the lighting component 20 to be above the
level of the loose, granular sand 46 to reflect light onto the
loose, granular sand 46. As described above, the at least one
lighting component 20 may be battery and/or electricity operated.
For example, lighting component 20 may be powered by battery 80. In
FIG. 3, for example, three lighting components 20 are depicted. The
lighting component 20 is located along an internal perimeter of the
mess-free sand play device 100 in order to prevent obstruction of
the clear window 16. The lighting component 20 may be evenly
distributed on one or more sides, or all sides, of the mess-free
sand play device 100 to allow for a uniform distribution of light
on the surface of the loose, granular sand 46. As further submitted
above, the lighting component 20 may be an LED lighting component
20 configured to change visible colors manually on demand via a
switch 40, or automatically cycle through the different visible
colors when the lighting component 20 is turned on. In a different
aspect, the clear window 16, itself, may comprise a lighting
component 20 configured to change into different visible colors
manually or automatically. It should be understood that the
lighting component 20 may be made available to enhance the play
experience with the mess-free sand play device 100; however, it is
not necessary for its operation.
[0034] FIG. 4 is an exploded view of various components of an
exemplary external stylus 26 in accordance with aspects herein. The
external stylus 26 may take any suitable shape for a comfortable
fit for an intended user's hands. FIG. 4, for example, shows
external stylus 26 having a pear-shaped handle 70. The handle 70 is
configured to securely enclose different components such as a
magnet 58 inside the handle 70. For example, the external stylus 26
may comprise at least a tip housing 62, a magnet 58, a woven or
non-woven fabric covering 60, and a retaining collar 64. In
accordance with aspects herein, the pear-shaped handle 70 may be
formed as a single piece or, in the alternative, in two or more
pieces. This may also be true for the tip housing 62 and the
retaining collar 64. When formed in two or more pieces, once the
pieces are fitted together, the different respective pieces for the
individual components may be glued together and/or heated or
ultrasonically welded together. As an additional added safety
feature, the pear-shaped handle 70 may further comprise one or more
screw anchors 56 to further hold one or more pieces of the
pear-shaped handle 70 together. The pear-shaped handle 70, the tip
housing 62, the magnet 58, the fabric covering 60, and the
retaining collar 64 may be configured to tightly fit together as,
for example, puzzle pieces, as further shown in FIG. 7.
[0035] FIG. 5A is an exploded view of various components of an
exemplary moveable device or internal stylus 28, in accordance with
aspects herein. As described above, moveable device or internal
stylus 28 comprises a foam tip 30. The foam tip 30 may be secured
to a magnet housing 32, the magnet housing 32 comprising at least a
magnet 52 secured within a case 54, woven or non-woven fabric or
textile covering 48, and a retaining collar 50. As can be observed
from FIG. 5A, the foam tip 30 may comprise an opening 98 configured
to fit a rod 96 of case 54, thereby immobilizing the foam tip 30.
The case 54 may further comprise a cavity 72 configured to fit one
or more magnets 52 and an unexposed portion of the foam tip 30. As
such, the internal stylus 28 may generally include a foam tip 30
opposite a magnet 52 within a housing device that maintains the
internal stylus 28 in a generally upright position within the
cavity 94.
[0036] In accordance with aspects herein, the case 54 may be
manufactured from a hard plastic, wood, or metal material, and the
retaining collar 50 may be manufactured from a rubber, plastic,
wood, or metal material. For example, these parts may be
manufactured from a polycarbonate plastic material, or other
material configured to secure a foam feature, a magnetic feature,
and the like. The foam tip 30 may be manufactured from a closed
cell foam material, or any other material configured to disperse
sand along a path within the cavity 94. Further, the magnet 52 may
be a permanent magnet. As shown, the magnet 52 may be disc shaped;
alternatively, the magnet 52 may be square shaped, triangle shaped,
or shaped in any suitable form to fit within cavity 72 of case 54,
depending on the shape of case 54. The foam tip 30 of the moveable
device or internal stylus 28, in accordance with aspects herein,
may comprise a closed cell foam structure having a height that is
less than or equal to a height 96 of the cavity 94 of the exemplary
mess-free sand play device 100, wherein the height 96 of the cavity
94 is measured from an interior surface 97 of the tray 12 to an
interior surface 98 of the cover 14.
[0037] FIG. 5B shows an alternative material for textile covering
48 for moveable device or internal stylus 28. For example, the
textile covering 48 for moveable device or internal stylus 28 may
comprise an uneven surface, such as shown, with a plurality of
loops 90, like the loops 90 shown on FIG. 5B. The uneven surface of
the textile covering 48 may be desirable to prevent sand granules
from becoming trapped between the interior surface of clear window
16 and the top surface 92 of textile covering 48. This is because
if sand granules were to become trapped between top surface 92 and
the interior surface of clear window 16, the trapped sand granules
may potentially scratch the interior surface of clear window 16
when the moveable device or internal stylus 28 is moved across the
clear window 16, thereby causing the mess-free sand play device to
become unsightly, and causing the view through clear window 16 to
be inhibited. With the plurality of loops 90, the moveable device
or internal stylus 28 is allowed to remain compressed against the
clear window 16, while any trapped sand granules are allowed to
fall through the loops 90 and back to tray 12 as the moveable
device or internal stylus 28 is pulled through the loose, granular
sand 46.
[0038] FIG. 6 is a side, perspective view of the external stylus 26
and the moveable device or internal stylus 28 showing their
interaction, in accordance with aspects herein. As seen from FIG.
6, when the magnetic tip 42 of the external stylus 26 and the top
surface 92 of the moveable device or internal stylus 28 are aligned
with each other, the magnet of the magnetic tip 42 is configured to
be attracted to the top surface 92 of moveable device or internal
stylus 28 via the magnet located within magnet housing 32. This
attraction allows for the manipulation of moveable device or
internal stylus 28 via the external stylus 26 when they are
provided as part of the mess-free sand play device 100.
Additionally, as discussed above, all components of external stylus
26 may be glued together, ultrasonically and/or heat bonded, and
for added safety, one or more screws 68 may be provided at one or
more screw anchors 56 to ensure that the external stylus 26 does
not open and fall apart, even in the event that the glued on part,
or heat or ultrasonically welded parts, fail. The one or more screw
anchors 56 may be recessed from the surface of the external stylus
26 so that the screws 68 are hidden from view and not readily
exposed.
[0039] FIG. 7 is a cross-sectional view along the plane passing
through the line 7-7 in FIG. 6 in accordance with aspects herein.
In FIG. 7, it can be readily observed how the different components
of external stylus 26 and the different components of moveable
device or internal stylus 28 are securely fitted together.
