Description
FIELD OF THE INVENTION
[0001] This invention relates to mobiles, for example mobiles
adapted for installation in a baby care device such as a crib or
playpen.
BACKGROUND OF THE INVENTION
[0002] The ability to recognize differences in the shapes and sizes
of various objects is not innate or inherent but must be acquired.
This is best taught at an early age by play, for the most effective
toy for a child is one which instructs as well as entertains the
player.
[0003] A classic toy serving to teach a child how to distinguish
between objects which differ in shape, color and size, provides a
player with a set of diverse geometric objects and a playing board
having apertures therein. Each aperture in the board has a geometry
which corresponds to only one of the pieces in the set. Hence when
a player seeks to fit a triangular piece into an aperture, by trial
and error he finds the one aperture in the board that will accept
the triangular piece. The child in playing with this toy must take
size into account. Thus if an aperture on the board is a circular
opening with a one inch diameter, it will not accept a circular
disc having a one-and-a-half inch diameter.
[0004] An infant who occupies a crib or a carriage is incapable of
manipulating geometric pieces to play with the above described toy.
However, this infant has powers of observation. Hence if geometric
objects that differ in shape, size and color are collectively
displayed, the infant learns to discern significant features among
these objects. This is particularly true if the collection of
objects is not in a static state and the objects are animated so
that they can each be seen in the round.
[0005] Since the invention relates to a mobile, of prior art
interest are the art mobiles created by Alexander Calder. These can
be seen in major museums of modern art.
[0006] In a Calder mobile, colored sheet metal pieces having
different geometries dangle from an armature that is supported from
a ceiling; the pieces being free to swing. The distribution of the
pieces and their relative weights are such that in a static state
the armature is balanced and the mobile then appears to be a work
of abstract sculpture. But the balance is upset by natural air
currents flowing in the space occupied by the mobile. These
currents impinge on the sheet metal pieces and cause them to sway,
thereby animating the mobile. Calder has also created works in
which the geometric pieces are maintained in fixed positions, this
being referred to as stabiles.
[0007] U.S. Pat. Nos. 3,638,602; 3,927,482; 3,983,647; 5,112,268;
5,620,274; 5,803,786 and 6,068,535 all disclose mobile
configurations which were deemed innovative in their time. This
list does not purport to be exhaustive.
[0008] U.S. Pat. No. 7,025,654 discloses a toy mobile comprising a
spider having a hub drivable by a motor to rotate the spider and
having at least two legs radiating from the hub at an angle thereto
and geometrical objects carried by the spider. Each leg has an end
terminal which in the course of each rotating cycle rises to a
level above the hub and then falls to a level below the hub,
causing the geometrical objects to be animated at least partially
under the influence of gravity.
SUMMARY OF THE INVENTION
[0009] A broad aspect of the invention relates to ways to impart
new types of motion to geometric objects affixed to a mobile. The
term geometric objects as used in the specification and
accompanying claims denotes any shape and pattern including, but
not limited to, planar geometric figures (e.g. circles, ellipses,
rectangles, squares, pentagons, hexagons and heptagons), three
dimensional geometric solids (e.g. spheres, ellipsoids, cubes,
rectangular solids, cones, pyramids, tetraheda, and other polygonal
solids) or figurative shapes (e.g. animals, people,
anthropomorphized objects and caricatures thereof). Optionally,
figurative shapes can be provided as two dimensional or three
dimensional objects. In various exemplary embodiments of the
invention, geometric objects may be colorful or with black and
white patterns or any other desirable pattern. Optionally, a
pattern and/or color scheme is selected in consideration of a
theory of child development. In some exemplary embodiments of the
invention, a mobile is designed to stimulate children of a
particular age. In some exemplary embodiments of the invention, a
motorized mechanism rotates the mobile. The term "motorized
mechanism" includes motors which rely upon an external power source
as well as those which rely on internally stored potential energy.
External power sources include, but are not limited to electric
power sources (e.g. batteries or a wall socket). Potential energy
can be provided, for example, using a coiled spring mechanism (e.g.
wind-up or pull string activated) as is known in the art.
[0010] An aspect of some embodiments of the invention relates to a
mobile having a hub, in which a force of gravity causes rotational
motion of a set of at least two concentric rings of different
diameters, each ring in the set mounted to rotate about its own
diametric axis which is not co-linear with respect to a diametric
rotary axis of at least one other ring in the set. In some
exemplary embodiments of the invention, each ring of a smaller
diameter is mounted to and within an adjacent ring of a larger
diameter, whilst the largest, outermost ring may be carried,
directly or indirectly by the hub so that its rotary axis is tilted
relative to a horizontal plane.
[0011] The term "horizontal plane" as used in this description and
the accompanying claims indicates a plane which is parallel to the
ground.
[0012] Optionally, one or more of the rings in the set rotate back
and forth through a defined arc (e.g. 30, 60, 90, 120 or 180
degrees) with respect to their own axis by alternating direction of
rotation. In some exemplary embodiments of the invention, a
motorized mechanism controls rotation of the hub around an axis
which is inclined with respect to a horizontal plane.
[0013] An aspect of some embodiments of the invention relates to a
mobile in which a force of gravity moves one or more geometric
objects along a track provided on a surface which rotates in a
plane at an angle with respect to the horizontal plane. In some
exemplary embodiments of the invention, the track is an undulating
track. Optionally, the track is provided as a slot in the surface.
In some exemplary embodiments of the invention, a motorized
mechanism controls rotation of the surface.
[0014] An aspect of some embodiments of the invention relates to a
mobile in which a one or more geometric objects are each suspended
from a pair of strings at separate attachment points on the object,
with a first string in the pair being attached to an external
support at a fixed point and a second string in the pair being
movably attached to an external support. External support, as used
here, indicates external to the geometric object. In some exemplary
embodiments of the invention, movably attached includes slidingly
attached. Optionally, the external supports of the first and second
strings are a same support or different supports. In some exemplary
embodiments of the invention, an angle between the external support
and the second string and/or between the second string and the
horizontal plane at the point of movable attachment of the second
string changes as the external support rotates.
[0015] In some exemplary embodiments of the invention, the point of
movable attachment of the second string to its external support
moves along the support in response to gravity as the support
rotates. Optionally, wind and/or a motorized mechanism contribute
to rotation of the external support.
[0016] An aspect of some embodiments of the invention relates to a
mobile including one or more support canopies, rotatable about its
rotary axis, with one or more geometric objects suspended
therefrom, the suspension of at least one such object being by
means of a pair of strings which have separate attachment points
with respect to the object and with respect to the canopy. In some
exemplary embodiments of the invention, a center of gravity of all
items suspended from a single canopy horizontally displaced with
respect to the rotational axis of the canopy. Optionally, the
rotational axis is provided at a geometric center of the
canopy.
[0017] In some exemplary embodiments of the invention, items
suspended from a single canopy include one or more geometric
objects each suspended as described above and a counterweight
suspended from the canopy by at least one additional string.
[0018] In other exemplary embodiments of the invention, items
suspended from a single canopy include one or more geometric
objects each suspended as described above and having a center of
gravity horizontally displaced with respect to the rotational axis
of the canopy.
[0019] In some exemplary embodiments of the invention, differential
loading of the canopy causes influence of gravity to contribute to
rotation of the canopy as the mobile rotates.
[0020] An aspect of some embodiments of the invention relates to a
mobile including a rotational control mechanism adapted to limit
rotation of at least one of the support canopies to a single
direction. In some exemplary embodiments of the invention, the
control mechanism employs a ratchet. Optionally, a resistance force
of the ratchet provides a threshold force. In some exemplary
embodiments of the invention, use of a threshold force causes the
canopy to perform a single rapid rotation through a defined arc
instead of a more gradual rotation. Optionally, the single rapid
rotation causes items dangling from the canopy to sharply move
thereby drawing attention of an infant observer thereto.
[0021] An aspect of some embodiments of the invention relates to a
mobile including at least one geometric object suspended from a
pair of strings which have separate attachment points with respect
to the object and with respect to an external support subject to
rotation, e.g. by a motorized mechanism, in a plane at an angle to
the horizontal plane. Optionally, a center of gravity, of the
object is not on a line between the attachment points of the
strings to the object. The strings attached to the object are a
same or a different length.
[0022] In some exemplary embodiments of the invention, each string
in the pair is fixedly attached to the external support.
[0023] In other exemplary embodiments of the invention, the first
string in the pair is fixedly attached to the external support and
the second string in the pair is movably attached to the
support.
[0024] As used in this specification and the accompanying claims,
the term "string" refers to any attachment means suitable for
flexibly suspending an object from an external support. In various
exemplary embodiments of the invention, a string can include a
thread, an actual string, an elasticized material (e.g. an elastic
band or rubber band), a rigid rod with a pivotal attachment point
at least one end, and a chain.
[0025] As used in this specification and the accompanying claims,
the term "support" should be interpreted in its broadest possible
sense so that it includes any structural element to which one or
more other described or claimed elements and/or objects can be
attached.
[0026] As used in this specification and the accompanying claims,
the term "support canopy" should be interpreted in its broadest
possible sense so that it includes any support adapted to provide
at least three attachment points in a non-linear array.
[0027] In some exemplary embodiments of the invention, there is
provided a mobile, the mobile including:
[0028] (a) a primary attachment point;
[0029] (b) a main support element attached thereto which is subject
to rotational displacement around an axis inclined with respect to
a horizontal plane;
[0030] and
[0031] (c) a set of at least two concentric rings including a main
ring having a primary axis with first and second ends which engage
said main support element so that during the rotational
displacement thereof the first end is sometimes above and sometimes
below the second end; and at least one additional ring having its
own axis whose ends engage the main ring, each of the rings being
rotatable about its corresponding axis.
[0032] As used in this specification and the accompanying claims,
the term "ring" should be interpreted in its broadest possible
sense so that it includes any curve with an axis of rotation.
Although circular rings are depicted and described, this circular
ring configuration is purely illustrative. Other possible ring
configurations include, but are not limited to, elliptical and
polygonal (e.g. hexagonal). In some exemplary embodiments of the
invention, not all rings in a set of concentric rings are
characterized by a same shape.
[0033] Optionally, at least one of the primary axis and the own
axis is a diametric axis of the corresponding ring.
[0034] Optionally, the rotational axis of the at least one
additional ring is not co-linear with respect to that of the main
ring and the rotational motion of one of the rings contributes to

DETAILED DESCRIPTION OF EMBODIMENTS
[0116] Various embodiments of the invention relate to mobiles with
unique mechanisms for imparting motion to one or more geometric
objects attached to one or more supports of the mobile.
[0117] Specifically, some embodiments of the invention can be used
to increase a degree of attractiveness of one or more geometric
objects to a viewer (e.g. an infant). Alternatively or
additionally, various embodiments of the invention use a force of
gravity to alter a spatial and/or a temporal pattern of motion
imparted by a non-gravitational force. Optionally, the
non-gravitational force includes a force supplied by a motor and/or
a force provided by ambient air currents.
[0118] The principles and operation of mobiles according to
exemplary embodiments of the invention may be better understood
with reference to the drawings and accompanying descriptions.
[0119] Before explaining at least one embodiment of the invention
in detail, it is to be understood that the invention is not limited
in its application to the details set forth in the following
description or exemplified by the Examples. The invention is
capable of other embodiments or of being practiced or carried out
in various ways. Also, it is to be understood that the phraseology
and terminology employed herein is for the purpose of description
and should not be regarded as limiting.
[0120] Overview
[0121] Referring concurrently to FIGS. 1, 2, 3, 4, 5 and 6 depicted
exemplary mobiles 100, 200, 300, 400, 500 and 600 share some common
features. Each of the depicted exemplary mobiles is supported by a
pole 26 and a base 20. According to various embodiments of the
invention, base 20 is configured to be attached to a flat surface
such as a vertical support 10 of FIG. 1. Exemplary external
vertical supports include, but are not limited to, bars 10 of a
crib or playpen. In other exemplary embodiments of the invention, a
hook (e.g. installed in a ceiling) replaces base 20 and/or pole
26.
[0122] Depicted exemplary bases 20 optionally include a mirror 22
and/or one or more user input devices generally depicted as buttons
24. Buttons 24 can optionally be employed to activate and/or
control rotation of the mobile and/or presentation of sounds (e.g.
music) and/or visual stimuli (e.g. lights).
[0123] Although pole 26 is depicted as being attached to the mobile
from above, in other exemplary embodiments of the invention, pole
26 is attached to the mobile from below.
[0124] Mobiles according to various embodiments of the invention
can be operated by a drive mechanism adapted to contribute to the
rotational displacement of main support 120. The drive mechanism
(not visible) can be provided in housing 28 and/or 38 and/or 48
and/or base 20.
[0125] Mobiles according to various embodiments of the invention
rotate about a primary attachment point depicted as 110, 210 or 310
in the various figures. In some exemplary embodiments of the
invention, a main support element is rotatable about an axis
passing through the primary attachment point and inclined relative
to a horizontal plane.
[0126] Rotational motion in a plane angled with respect to a
horizontal can be achieved, for example, using the teachings of
U.S. Pat. No. 7,025,654 to Oren et al. One of ordinary skill in the
art will easily be able to adapt the teachings of Oren et al. for
implementation in the context of various embodiments described
hereinbelow.
EXEMPLARY NESTED RINGS EMBODIMENT
[0127] FIG. 1 depicts exemplary mobile 100 including a primary
attachment point 110 and a main support element 120 including
optional fixed ring 150 attached thereto, rotatable about an axis
passing through the primary attachment point and inclined relative
to a horizontal plane The support element 120 with its fixed ring
is subject to rotational displacement around a mobile rotary axis
passing through the primary attachment point 110, which is inclined
to a horizontal plane.
[0128] Depicted exemplary mobile 100 includes a set of concentric
rings 130 and 140 including a main ring 130 and an additional ring
140, each of the rings rotatable about its own axis. In particular,
the main ring 130 has axles 132 and 134 attached to the support
element 120 and collinear with a diametrical axis of ring 130 so
that, upon the rotation of the support element 120, axle 132 is
sometimes above and sometimes below axle 134. The words "above" and
"below" as used with regard to ends 132 and 134 mean that
horizontal planes in which the respective ends reside have the
indicated relationship.
[0129] The additional ring 140 has axles 142-144 attached to main
ring 130 and collinear with a diametrical axis of the ring 140
which is oriented transversely to the diametric axis of the main
ring 130.
In the depicted embodiment, a geometric object 160 (depicted as a
star) is mounted on an axle 162 attached to the additional the ring
140 The additional ring 140 carries an object 160 which is attached
thereto by axle 159-161 at locations spaced from the ends 142 and
144 of the diametrical axis of the ring, and is adapted for
rotation thereabout. Each of the rings 130 and 140 is adapted to
rotate back and forth through a defined arc with respect to its own
axis. In various exemplary embodiments of the invention, the
defined arc can be 30, 60, 90, 120, 180 degrees or lesser or
intermediate or greater angles.
[0130] Optionally, additional objects 152 are suspended from the
fixed ring 150. In the depicted embodiment, additional objects 152
are equally spaced from the fixed ring 150, although in other
embodiments of the invention, objects 152 of different weights can
be spaced at unequal intervals so that their weight is evenly
distributed.
[0131] As main support 120 with the fixed ring 150 rotate about the
mobile rotary axis, gravity causes rotation of rings 130 and/or 140
and/or object 160 about their respective axes, for reasons
described below with reference to FIG. 6.
[0132] Referring now to FIG. 6, exemplary influences on rotational
motion of the various rings is explained. In depicted exemplary
mobile 600, main support 120 including optional fixed ring 150
rotate about a mobile rotary axis B-B passing through attachment
point 110 and inclined at an angle of about 40 degrees with respect
to the horizontal plane. Optionally, alteration of this angle of
inclination influences rotation of rings 140 and/or 130 and/or
object 660 with respect to their respective axes. Optionally,
decreasing the angle of inclination contributes to a reduction in
rotation of rings 140 and/or 130 and/or object 660.
[0133] Alternatively or additionally, axis A-A of ring 130 and axis
C-C of ring 140 are deployed at an angle of less than 90 degrees
with respect to one another. Optionally, the angle between these
axes is about 15 to 45 degrees, optionally about 20 to 30 degrees,
optionally about 25 degrees
[0134] Alternatively or additionally, ring 140 can be weighted at a
point opposite a rotational axis 662 of star 660 as a means of
increasing its tendency to rotate about its axis C-C.
[0135] Alternatively or additionally, an object in the center of
ring 140 (e.g. star 660 of FIG. 6 or star 160 of FIG. 1) is
asymmetrically weighted to encourage rotation of the object about
its axis as optional fixed ring 150 of main support 120
rotates.
[0136] Additional objects 652 are suspended from optional fixed
ring 150 of main support 120 from fixed attachment points 654.
[0137] Alternatively or additionally, additional objects 653 are
suspended from optional fixed ring 150 of main support 120 from
movable attachment points 655. In the depicted exemplary
embodiment, movable attachment points 655 are provided as beads
seated in grooves 657. Optionally, a length of groove 657
contributes to a degree of movability of the attachment.
EXEMPLARY CANOPIES/PAIR OF STRINGS--EMBODIMENT
[0138] Referring now to FIG. 2, an additional exemplary mobile 200
includes a primary attachment point 210 and a main support element
(depicted as arms 220, 222 and 224) attached thereto. As in the
exemplary embodiment of FIG. 1, the main support is subject to
rotational displacement with respect to primary attachment point
210 about an axis passing therethrough at an angle with respect to
a horizontal plane. Optionally, the angle with respect to the
horizontal plane is about 40 degrees. Optionally, main support
depicted as arms 220, 222 and 224 can be replaced by a ring like
structure similar to 150 of FIG. 1.
[0139] In the depicted exemplary embodiment of the invention, three
support canopies 230, 232 and 234 are pictured. In other
embodiments different numbers of support canopies may be provided.
Each of the depicted support canopies 230, 232 and 234 has at least
one geometric object (240, 242 and 244 respectively) suspended
therefrom by at least two strings (e.g. pairs 250 and 260; 252 and
262; and 254 and 264 respectively) fixedly attached to their
respective canopies. In the depicted embodiment, objects 240, 242
and 244 are styled as animal caricatures (monkey, giraffe and
elephant respectively). In other exemplary embodiments of the,
objects 240, 242 and 244 can be styled in accord with other themes
(e.g. ocean creatures, space travel, car race and circus).
[0140] The at least two strings (pairs 250 and 260; 252 and 262;
and 254 and 264) are fixedly attached to geometric objects (240,
242 and 244 respectively) at separate points of attachment on the
object (e.g. 270 and 280; 272 and 282; and 274 and 284
respectively). Optionally, positioning of a center of gravity of
the object with respect to the separate points of attachment
contributes to additional motion of the object suspended from the
strings.
[0141] Mobile 200 includes an optional counterweight (e.g. 290, 292
and 294) suspended from each canopy (230, 232 and 234) by at least
one additional string (291, 293 and 295). The counterweight may
contribute to rotational motion of the canopy as the main support
rotates.
[0142] Optionally, a center of gravity of one or more of objects
240, 242 and 244 is not co-linear with the separate points of
attachment (e.g. 270 and 280; 272 and 282; and 274 and 284
respectively) of the at least two strings on the object (pairs 250
and 260; 252 and 262; and 254 and 264 respectively).
[0143] In some exemplary embodiments of the invention, the at least
two strings are of a same length (e.g. 250 and 260).
[0144] In some exemplary embodiments of the invention, the at least
two strings are of different lengths (e.g. 254 and 264 and/or 252
and 262).
[0145] The support canopies 230, 232 and 234 are rotatably attached
to the main support. Exemplary points of rotational attachment are
depicted as 231, 233 and 235 and define axes of canopy rotation
with respect to the main support element.
[0146] The support canopies 230, 232 and 234 each include a
rotational control mechanism adapted to control rotation of the
support canopy with respect to the main support 220. The mechanism
is installed at points of rotational attachment 231, 233 and 235
and permits rotation in one direction only. Optionally, the
mechanism imposes a rotation threshold which must be overcome for
the corresponding canopy to rotate. The rotational control
mechanism may include a ratchet mechanism. This mechanism can
contribute to a more pronounced rotational motion of the
canopy.
[0147] Optionally, as the main support (e.g. 222) rotates around
attachment point 210 at an angle to the horizontal, object 242
and/or counterweight 292 apply a varying degree and/or direction of
rotational force to rotational attachment point 233 of canopy 232.
In some exemplary embodiments of the invention, gravity contributes
to the variation.
[0148] Referring now to FIG. 5, exemplary mobile 500 is similar to
mobile 200 of FIG. 2 in many ways. Mobile 500 rotates about
attachment point 210 and includes three canopies 230, 232 and 234
which rotate about points 231, 233 and 235 respectively.
[0149] In depicted exemplary mobile 500, geometric objects in the
shape of animals are suspended from the canopies. A horse including
a body 540 connected by a flexible neck 570 to a head 550 is
suspended by a pair of strings 580 from attachment points 560 and
562 of canopy 230. A bird including a body 544 connected by a
flexible neck 570 to a head 554 is suspended by a pair of strings
from attachment points 560 and 562 of canopy 234. A monkey
including a body 542 and a head 552 is connected by a flexible arm
570 to one of a pair of strings 580 connecting the monkey to
attachment points 560 and 562 of canopy 232. Thus, each of the
depicted animals includes a flexible member positioned between the
two strings. The animals are unevenly weighted so that a center of
gravity of the animal does not reside on a rotational axis of the
canopy of the relevant canopy. As a result, gravitational force
acting on the center of gravity of the animal contributes to
rotation of the canopy from which the animal is suspended as the
mobile rotates about 210.
EXEMPLARY MOVABLY ATTACHED STRINGS EMBODIMENT
[0150] FIG. 3 depicts an exemplary mobile 300 according to some
embodiments of the invention. Depicted exemplary mobile 300
includes a primary attachment point 310 and a main support element
320 attached thereto and subject to rotational displacement with
respect to primary attachment point 310 and inclined with respect
to a horizontal plane.
[0151] The mobile 300 includes geometric objects 330, 340 and 350
each suspended from main support element 320 by a first string
(332, 342 and 352) attached to main support 320 at a fixed point
and a second string (334, 344 and 354) movably attached to main
support 320.
[0152] The second string 334, 344, 354 is subject to gravitational
forces and moves back and forth along main support 320 as the main
support rotates with respect to main attachment point 310. This is
achieved by the second strings 334, 344, 354 being slidingly
attached to main support 320, by beads 360. In the depicted
embodiment, beads 360 are fashioned to resemble a center of a
flower 362. Other configurations of bead 360 will suggest
themselves to one of ordinary skill in the art according to a theme
of mobile 300.
[0153] In the depicted exemplary embodiment, first strings 332, 342
and 352 and second strings 334, 344 and 354 are attached to
geometric objects 330, 340 and 350 at separate attachment points on
their respective objects so that a center of gravity of the
geometric object is not between the separate attachment points on
the object. Optionally, a center of gravity of the geometric object
is co-linear with the separate attachment points on the object. In
some exemplary embodiments of the invention, a center of gravity of
the geometric object which is co-linear with the separate
attachment points on the object but not between the attachment
points contributes to a tendency of the object to oscillate along
its long axis with respect to main support 320 as main support 320
rotates.
[0154] In the depicted exemplary embodiments of the invention, main
support 320 includes a continuous piece which surrounds primary
attachment point 310. In particular, the main support 320 is
provided as a closed undulating curve as depicted. In other
exemplary embodiments of the invention, the main support may be
provided as a plurality of separate pieces.
[0155] The mobile 300 further includes geometric objects (370 and
372) adapted to move along a track 374 within main support 320 in
response to its rotational displacement, as will be described
further in more detail. In some exemplary embodiments of the
invention, the track does not lie along a rotational orbit about
the primary attachment point defined by any point on the track.
[0156] FIG. 4 depicts an additional exemplary mobile 400, similar
to mobile 300 of FIG. 3 in many ways. In depicted exemplary mobile
400, primary attachment point 310 and main support 320 are
substantially as described hereinabove. Geometric objects 430, 440
and 450 (depicted here as animal caricatures) are each suspended
from main support element 320 by a single string 460 movably
attached to main support 320 by a sliding bead 360 as described
above. In some exemplary embodiments of the invention, beads 360
are separated from one another by a motion limiting adapted to
limit motion of beads 360 with strings 460 along main support
element 320
[0157] Optionally, the motion limiting element includes at least
one object 482 affixed to main support element 320 and/or points of
attachment 480 of surface 380 supported by main support element
320. Alternatively, the motion limiting element may be in the form
of projections 710 constituting an integral part of the main
support element 320. (FIGS. 3B and 4B). In this case, objects 482
have solely decorative function. There may also be a combination of
objects 482 and 710 in a single mobile.
[0158] Alternatively or additionally, the motion limiting element
includes a slot 657 which limits motion of bead 655 with respect to
support element 120 and/or 150 (FIG. 6).
EXEMPLARY MOTION ALONG A TRACK EMBODIMENT
[0159] Referring again to FIGS. 3 and 4, the main support element
320 includes a surface 380 in which geometric objects 370 and/or
372 move along a track 374 in response to the rotational
displacement of the surface along an axis inclined relative to a
horizontal plane. under the influence of gravity. Although tracks
374 are depicted as somewhat parallel tracks, they can optionally
be provided in other arrangements.
[0160] In the depicted exemplary embodiment, track 374 is formed in
the surface 380 attached to main support 320. In other exemplary
embodiments of the invention, track 374 is directly attached to
main support 320 (e.g. in the form of a wire.). In the depicted
exemplary embodiment, track 374 defines an undulating curve. In the
depicted embodiment, track 374 is provided as a slot in surface
380.
[0161] Exemplary Materials
[0162] Many exemplary embodiments of the invention are designed
and/or configured for deployment in infant cribs and/or playpens.
Optionally, materials for construction of various portions of the
mobile are selected with that use in mind.
[0163] For example, structural elements such as pole 26 and/or base
20 and/or supports 120 and/or 220, 222 and 224 and/or 320 and/or
surface 380 are optionally constructed from high impact plastic
(e.g. polyvinylchloride or polycarbonate) and/or reinforced with
metal. Various suspended objects described hereinabove can be
constructed of plastic and/or fabric as desired. Optionally,
suspended objects are provided as fabric dolls filled with
lightweight materials (e.g. cotton batting) and weighted (e.g. with
high density plastic weights) to achieve a center of gravity in a
desired position relative to the doll and/or a support canopy or
other support element above the doll.
[0164] Exemplary Themes
[0165] In some exemplary embodiments of the invention, objects
and/or supports within a specific mobile are designed and/or
configured to adhere to an overall theme of a mobile.
[0166] Exemplary overall themes include, but are not limited to,
"Ocean in motion" (for example as depicted in FIGS. 1 and/or 6)
and/or "Sweet Island dreams" (for example as depicted in FIGS. 2
and/or 5) and/or "Nature's soothing serenade" (for example as
depicted in FIGS. 3 and/or 4).
[0167] Optionally, geometric items are provided as figures which
are thematically consistent with music played by a music box
provided as part of the mobile.
[0168] It is expected that during the life of this patent many
motor mechanisms and/or rotational control mechanisms will be
developed and the scope of the invention is intended to include all
such new technologies a priori.
[0169] Although the invention has been described in conjunction
with specific embodiments thereof, it is evident that many
alternatives, modifications and variations will be apparent to
those skilled in the art. Accordingly, it is intended to embrace
all such alternatives, modifications and variations that fall
within the spirit and broad scope of the appended claims.
[0170] Specifically, a variety of numerical indicators have been
utilized. It should be understood that these numerical indicators
could vary even further based upon a variety of engineering
principles, materials, intended use and designs incorporated into
the invention. Additionally, components and/or actions ascribed to
exemplary embodiments of the invention and depicted as a single
unit may be divided into subunits. Conversely, components and/or
actions ascribed to exemplary embodiments of the invention and
depicted as sub-units/individual actions may be combined into a
single unit/action with the described/depicted function.
[0171] Alternatively, or additionally, features used to describe a
method can be used to characterize an apparatus and features used
to describe an apparatus can be used to characterize a method.
[0172] It should be further understood that the individual features
described hereinabove can be combined in all possible combinations
and sub-combinations to produce additional embodiments of the
invention. The examples given above are illustrative in nature and
are not intended to limit the scope of the invention which is
defined solely by the following claims. Specifically, the invention
has been described in the context of mobiles for infants but might
also be used for other types of mobiles, for example large scale
Calderian mobiles provided as art installations.
