BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to artificial plants
or trees, and to an improved artificial tree apparatus that is
easily assembled, disassembled, and transported by any means
including by rail and fork-truck, and which may be of any suitable
size and height from a few centimeters to twenty meters or even
more depending upon a user's desire. More specifically, the present
invention is directed to portable and retractable artificial trees
having separable, modular tree portions mechanically connectable,
controllable and lockable between trunk and branch portions, and
which may be controlled by direct wire control, by remote control
(wireless via Radio Frequency (RF), Infra-Red (IR), BlueTooth.RTM.,
or any other remote control convention), and via one or a series of
process controllers by remote signals sent over an electronic
medium (e.g., control signals sent via an Internet portal from a
distant unit, desk-top, hand-held-PDA-type unit, or otherwise).
[0004] 2. Description of the Related Art
[0005] Artificial trees are well known. Most artificial trees
comprise a multiplicity of separate branches each formed of a
plurality of plastic needles held together by twisting a pair of
wires about them. In other instances, the branches are formed by
twisting a pair of wires about an elongated sheet of plastic
material having a large multiplicity of transverse slits. In still
other artificial trees, the branches are formed by injection
molding of plastic.
[0006] Irrespective of the form of branch, the most common form of
artificial tree comprises a wooden simulated trunk having a
plurality of spaced apart apertures for reception of branches
therein to thereby hold the branches in radially extending relation
to the trunk to form the artificial tree. For purposes of storage,
the branches are removable, requiring the repositioning of the
branches on the trunk each time the tree is reassembled. The
difficulty of this task is, however, somewhat reduced by color
coding the apertures on the trunk with the ends of the
branches.
[0007] To provide a tree which can be stored without occupying an
unduly large amount of space and yet to avoid the need for totally
dismantling the tree and re-assembling for further use, it has been
previously proposed to permanently pivotally affix the artificial
branches of an artificial tree to the trunk thereof to permit
movement of the branches between an outwardly deployed position and
a storage position in which the branches lie close to the trunk and
thereby occupy a comparatively small space. However, such trees
require elaborate assembly techniques, and somewhat complex
structure, thereby rendering both of these prior art patents of
little importance in commercial development of artificial
trees.
[0008] Also known are artificial trees with foldable branches. The
structures disclosed therein, however, require that the trunk be
apertured to permit insertion of either the rear ends of the
branches or of a branch connecting member therein. In addition, the
structure requires some form of bifurcation at the ends of the
branches, which bifurcation requires special tooling not heretofore
employed in the making of artificial trees.
[0009] To avoid the necessity of aperturing the trunk, it has been
suggested to provide a branch holder which may be secured to the
trunk of the tree and to which a branch or branches may be secured
for pivotal movement between an extended position and a collapsed
position. For example, a branch holder for pivotally securing a
single branch to the trunk has been provided. However, the separate
manipulation of branches for deployment and storage is time
consuming and conducive to uneven deployment of the branches.
[0010] Artificial trees constructed of metal and/or plastic have
become more commonly substituted for natural evergreen trees when
decorating homes, offices, and other spaces, both indoors and
outdoors. Such artificial trees generally include multiple tree
sections joined at the trunk and held erect by a floor-based tree
stand. Sometimes, consumers wrap strings of lights about the
artificial tree (e.g., a Christmas tree) to enhance the decorative
quality of the tree display. Some artificial trees are "pre-lit"
trees to ease the burden on consumers of decorating the tree with
strings of lights. Typical pre-lit trees include an artificial tree
with multiple standard light strings distributed about the exterior
of the tree. Wires of the light string are clipped to branch
structures, while plug ends dangle throughout the branches.
[0011] Often, in both non-pre-lit and pre-lit trees, the connection
of light strings spans more than one trunk section. If a particular
trunk section is allowed to spin, the wiring of the light strings
can become twisted. When twisted, light strings are at risk of plug
and end connector damage and are even at risk of breaks. Safety can
therefore be compromised if a trunk section is allowed to spin.
Further, if a particular trunk section is allowed to spin, the tree
can be difficult to decorate, as it can be difficult to arrange
light strings or ornaments on a moving section of tree.
Additionally, trees are often placed in the corners of rooms or up
against walls. Once decorated, it is desirable for the sections of
the tree to remain fixed, as the wall-facing or corner-facing sides
are often left undecorated. It is therefore beneficial for
artificial tree trunk sections to remain fixed in place.
[0012] Similarly, a sloppy fit between trunk sections can create
wobble or unwanted tilt between sections. This can leave the tree
unstable and at risk of toppling if bumped or touched. Also, a
non-vertical section is undesirable from an aesthetic perspective,
as a slanted tree looks visually less impressive than a perfectly
vertical tree. Therefore, it is desirable to have an extremely
tight fit between tree trunk sections which ensures a completely
vertical tree.
[0013] Additionally, as the popularity of both pre-lit and
non-pre-lit artificial trees has grown, so to have the bulk and
complexity of artificial trees. Not only has the number and density
of branches of a typical artificial tree increased, but, for
pre-lit trees, the increase in number and density of branches
likewise increases the number of lights and light strings. As a
result, the weight and bulk of artificial trees has increased, thus
making it difficult to lift and align individual trunk sections
when assembling the tree.
[0014] Further adding to the difficulty of lifting and aligning
individual trunk sections is the advent of the locking trunk
section. Manufacturers have created a number of artificial trees
that have locking trunk sections. These trunks have either a
protrusion or void, respectively, and are insertable in only one
rotational alignment into the corresponding void or protrusion,
respectively, of the receiving trunk portion. Such a design
provides a friction fit such that the two trunk portions cannot
spin relative to one another. However, as mentioned above, because
of the weight and bulk of the artificial trees, it is often
difficult to perfectly align the individual trunk sections.
Consumers must first locate the alignment mark on the receiving
portion, then locate the corresponding alignment mark on the
insertable portion, and finally adjoin the two perfectly in the
identified alignment. Thus, it is desirable for trunk sections to
fit universally in any rotational orientation with the receiving
portion of the receiving trunk to provide a secure, tight fit
between trunk sections.
[0015] Some known inventions have attempted to make artificial
trees more convenient to put together. For example, a simple
artificial tree with one embodiment having multiple tree sections
that join together is known. The tree includes single bulbs at each
end of a branch, with bulb wiring extending from inside a trunk
through hollow branches. A bayonet fitting is used to adjoin the
sections, a top section having a projecting pin, and a bottom
section having an L-shaped bayonet slot. The two sections are
coupled by aligning the projection pin with the bayonet slot and
rotating to interlock the sections, thereby bringing a pair of
spring contacts into alignment with a pair of terminals to make an
electrical connection.
[0016] Another known artificial tree is a pre-lit tree made in
sections which may be folded for easy storage. The individual tree
sections include a threaded male end and a threaded female socket
end. The male end of a tree section is screwed into the female end
of another section. Wiring for the lights passes from the trunk
through holes in branches and connects with individual lights at an
interior of the branch. When the tree is screwed together, an
electrical connection is made.
[0017] In another example of an artificial tree an internal sleeve
sized to receive a tree trunk is utilized. The sleeve is coupled to
a base section and positioned to receive the tree trunk. The sleeve
is provided with longitudinally aligned friction strips that are
spaced apart and tapered in height to increase the amount of
friction presented to an inserted trunk. When the trunk cylinder is
inserted into the sleeve, the friction strips of the sleeve press
against the wall of the trunk to secure the tree.
[0018] One such combination artificial tree-lighting arrangement
includes a generally elongated tree trunk. The combination also
includes a plurality of connecting components mountable on the tree
trunk and a plurality of display components mountable on the
connecting components. Each display component has tree limbs and
lighting cables extending therefrom. The lighting cables are
provided with decorative lights. An electrical circuitry
connectable to an electrical power source is attachable to the
connecting components. The electrical circuitry includes a
connecting component-to-light coupling arrangement for electrically
coupling the connecting components to the decorative lights. The
connecting component-to-light coupling arrangement allows the
display components to rotate relative to the connecting components
about a rotation axis substantially parallel to the trunk
longitudinal axis while maintaining the electrical coupling between
the connecting components and the decorative lights.
[0019] Another such artificial tree includes a plurality of twigs,
a channel element, a number of inserts, and a hook-like member.
Each twig is inserted through an aperture in the insert and the
insert, in turn, is placed in and secured in the channel element.
The hook-like member has a short side used to secure the branch to
an artificial trunk and a long side secured in the channel element.
Optical fibers are associated with the twigs of the panel branch.
Each optical fiber is threaded through an aperture in an insert and
gathered into a bundle. A socket with a light source is provided to
receive the bundle of optical fibers such that the branch is
lighted.
[0020] There also exists an illuminated artificial tree having a
display position and a folded position constructed of an odd number
of upright wire mesh panels hingedly attached at their vertical
inner edges, the panels including a first end panel, a second end
panel and a plurality of intermediate panels between the first and
second end panels. A string of decorative lights are attached in a
plurality of spaced, reversed loops, the string extending from
adjacent the lower edge of the first panel around the intermediate
panels to the second panel, then upwardly along the outer edge of
the second panel, and then back around the outer edges of the
intermediate panels to the first panel, thereby permitting folding
of the tree without removal of the light string.
[0021] Another artificial tree structure with decorative lamps
includes a plurality of hollow tubes or iron wires of various
lengths, in the shape of tree branches, arranged from top to bottom
around the main trunk supported by detachable legs. On each side
sticks are installed a plurality of iron wires to form the shape of
tree branches. The exterior of the hollow tubes or iron wires is
wound by dense tree leaves. The lamps installed in the hollow tubes
or on the iron wires are serially connected to become decorative
lamp strings. The decorative lamp strings are then combined in
parallel connection, running down the main trunk to be connected to
a control box and a power transformer. The structure described
above provides the artificial tree with decorative lamps, using the
control box to produce music and lighting effects of different
luminosity and flashing speeds.
[0022] Still another artificial tree includes a central trunk, a
number of main branches suspended from an upper portion of the
trunk in a downwardly and outwardly inclined orientation, and a
preformed tree top section extending upwardly from the upper
portion of the trunk. Each main branch includes a number of
sub-branch clusters and a bundle of fiber optic conduits which
terminate in the sub-branches. The bundles of fiber optic conduits
are received in an opaque enclosure housing a high intensity light
source, which enclosure is attached to the upper portion of the
trunk. Electric lights are disclosed as an alternative means to
illuminate the tree. The trunk includes upwardly open hook elements
which receive pin elements within the interior of rigid support
members of the main branches. Each sub-branch cluster is pivotally
connected to an associated rigid support member to articulate
between a collapsed position for storage and shipping, and an
extended position for display.
[0023] Yet another artificial tree comprises both an artificial
tree, having a stand and trunk with attachable branches, and
various electrical components. The trunk portion of the tree is
composed of a plurality of coupled sections which are joined
together in a vertical orientation, and each of which has holes for
branches to be inserted. The trunk pieces also have electrical
sockets which are internally connected to the base of the trunk.
The base of the trunk has attached to it another electrical socket
and a master power cable. In use, the tree is assembled as any
standard artificial tree, connecting trunk pieces together, and
inserting into them branches of various sizes. Any conventional
ornament or lighting fixture may be hung on these branches, and
plugged into the trunk for power requirements. A stand at the base
of the trunk provides stability, and internal circuit breakers
provide assurance against fire. A line from the trunk is plugged
into a powered electrical to provide power to the entire tree.
[0024] Also known is an illuminated artificial tree in which a
plurality of branches extend from a trunk of the tree, each branch
being formed by spirally winding a strip assembly of a plurality of
juxtaposed fiber optic elements and simulated pine needles on an
elongated support wire. The fiber optic elements and simulated pine
needles extend around the wire in adjacent relation to provide an
interspersed array of pine needles and fiber optic elements all
along the length of the branch. The fiber optic elements are
illuminated at the base of the tree to provide points of light
substantially all around each branch along its entire length. A
number of branches are assembled along the trunk from the top
down.
[0025] The foregoing generally reflects the current known state of
the art. However, such known trees still require significant
manipulation and handling of the tree sections to securely align
and couple the sections together. Further, such known trees fail to
disclose adequate mechanical coupling and connection devices and
methods that allow for a universal, snug fit that meet the needs of
consumers utilizing artificial trees. It is believed that none of
the above discloses, teaches, suggests, shows, or otherwise renders
obvious, either singly or when considered in combination, the
invention described and claimed herein.
[0026] Accordingly, there is a need for an improved artificial tree
that is automatically or manually easily retractable so as to
minimize or prevent damage due to, for example, wind by improving
the control of the artificial branch limbs and leaf limbs on such
artificial trees. Further, there is also a need to improve the
efficiency of assembly, retraction, storage and portability of
artificial trees.
ASPECTS AND SUMMARY OF THE INVENTION
[0027] The present invention substantially meets the aforementioned
needs of the industry. An apparatus for a portable and retractable
artificial tree, the apparatus comprising a plurality of trunk
members having a generally cylindrical body with an outer wall and
an inner cavity, the trunk members each having an upper portion and
lower portion, wherein the upper portion of a first one of the
trunk members has an outside diameter for interconnecting with the
lower portion of a second one of the trunk members when brought
into juxtaposition with each other; a plurality of branch
assemblies each connected to an opening on the outer wall of at
least one of the trunk members; and a plurality of lever arms
disposed within the inner cavity having upper ends pivotably
attached to the branch assemblies to allow control of the branch
assemblies by movement of the lever arms in vertical paths within
the inner cavity. The tree has an elongated trunk and a series of
branch assemblies spaced upon its trunk mechanically and
electrically interconnected to a base device for retracting,
expanding, or otherwise controlling the branch assemblies.
Optionally, the base controller may retract, expand, reposition or
otherwise control a plurality of secondary branch assemblies (or
leaf or power generation (solar-type) assemblies) positioned along
each of the branch assemblies. The invention also allows for
operational and manipulation control by direct wired control, by
remote control (wireless via Radio Frequency (RF), Infra-Red (IR),
BlueTooth.RTM., or any other remote-control convention), or via one
or a series of process controllers by remote signals sent over an
electronic medium (e.g., control signals sent via an internet
portal from a distant unit, desk-top, hand-held-PDA-type unit, or
otherwise).
[0028] Preferably, the artificial tree branch assembly contains a
plurality of secondary branch assemblies, where the secondary
branch assemblies are either uniformly or non-uniformly spaced
apart from one another upon each of the branch assemblies. Also, in
the expanded state the branch assemblies extend outwardly at an
angle of between about 30 to 90 degrees with respect to the trunk.
When in a narrow state the branch assemblies extend outwardly at an
angle of between about 0 to 30 degrees with respect to the
trunk.
[0029] Another embodiment of the present invention provides a
portable and retractable artificial tree transformable between a
narrow vertical state and an expanded state, wherein the artificial
tree comprises a generally cylindrical rigid trunk having upper and
lower ends, the trunk having an outer wall and an inner cavity; a
base constructed to engage the lower end to support the trunk in a
substantially vertical upright position; a plurality of branch
assemblies interconnected with the trunk through openings in the
outer wall; and a plurality of lever arms disposed within the inner
cavity having upper ends pivotably attached to the branch
assemblies to allow movement of the lever arms in vertical paths
within the cavity and provide movement of the branch assemblies;
wherein each the branch assembly is pivotably attached to at least
one of the plurality of lever arms by extending through a borehole
in the trunk; and whereby controlled sliding movement of the lever
arms causes the branch assemblies to be displaced from the trunk
upwardly angled therefrom to produce an expanded state of the tree,
and opposite controlled movement of the lever arms causes the
branch assemblies to be drawn close to the trunk in substantially
parallel alignment therewith to produce a narrow state of the
tree.
[0030] According to another embodiment of the present invention, a
coupling mechanism like a securing sleeve or securing plug is
provided to assist in joining two sections of artificial tree
trunk. The sleeve or plug is receivable in a lower trunk portion
and subsequently provides an aperture for receiving an upper trunk
portion. The sleeve is made, for example, of plastic or rubberized
material, thus making it more malleable than the metal or other
nonmalleable trunk material. As such, the sleeve is able to form to
the shape of both trunk portions and within any gaps present due to
imperfections in the machining process to provide a more secure fit
than coupling the trunk portions directly. As such, the sleeve
provides a locking mechanism for the connected trunk portions.
Thus, trunk portions are not allowed to spin relative to one
another and remain fixed in place. There is no risk of light string
damage due to twisting of the trunk sections. Additionally, the
tree is easier to decorate, as the sections remain in one secured
configuration. Further, one decorated, the tree is fixed in place.
Also, such a fit provides for a perfectly upright tree. No tilt or
wobble between trunk portions is allowed, thus making for a more
visually appealing and safer tree.
[0031] The present invention relates to an apparatus for a portable
and retractable artificial tree, the apparatus comprising a
plurality of trunk members having a generally cylindrical body with
an outer wall and an inner cavity, the trunk members each having an
upper portion and lower portion, wherein the upper portion of a
first one of the trunk members has an outside diameter for
interconnecting with the lower portion of a second one of the trunk
members when brought into juxtaposition with each other, a
plurality of branch assemblies each connected to an opening on the
outer wall of at least one of the trunk members, and a plurality of
lever arms disposed within the inner cavity having upper ends
pivotably attached to the branch assemblies to allow control of the
branch assemblies by movement of the lever arms in vertical paths
within the inner cavity.
[0032] Also provided is an artificial tree apparatus wherein the
first trunk member upper portion comprises a reduced diameter and a
detent for interconnection with the second trunk lower portion
having a guide slot, wherein at least one of the branch assemblies
further comprises one or more secondary branch assemblies connected
to the lever arms through openings in the one of the branch
assemblies. In addition, the lever arms may control the vertical
movement of the branch assemblies and/or the vertical or lateral
movement of the secondary branch assemblies. The detent on the
upper portion of one of the trunk members is positioned for
alignment with a recess in the lower portion of the second one of
the second trunk member. The lever arms are preferably located in
the inner cavity and are accessed through the outer wall.
[0033] The artificial tree apparatus may further comprise a base
device for maintaining the trunk in a substantially vertical
position, the base device housing a controller for controlling the
branch assemblies using the lever arms. Preferably, a lower most
portion of the trunk is attached to the base device, and an
electrical line may be positioned in the inner cavity, and wherein
the outer wall may include one or more electrical receptacles
connected to the electrical line.
[0034] Also disclosed is a portable and retractable artificial tree
transformable between a narrow vertical state and an expanded
state, wherein the artificial tree comprises a generally
cylindrical rigid trunk having upper and lower ends, the trunk
having an outer wall and an inner cavity; a base constructed to
engage the lower end to support the trunk in a substantially
vertical upright position; a plurality of branch assemblies
interconnected with the trunk through openings in the outer wall;
and a plurality of lever arms disposed within the inner cavity
having upper ends pivotably attached to the branch assemblies to
allow movement of the lever arms in vertical paths within the
cavity and provide movement of the branch assemblies; wherein each
the branch assembly is pivotably attached to at least one of the
plurality of lever arms by extending through a borehole in the
trunk; and whereby controlled sliding movement of the lever arms
causes the branch assemblies to be displaced from the trunk
upwardly angled therefrom to produce an expanded state of the tree,
and opposite controlled movement of the lever arms causes the
branch assemblies to be drawn close to the trunk in substantially
parallel alignment therewith to produce a narrow state of the
tree.
[0035] The artificial tree according to the invention further
includes each branch assembly containing a plurality of secondary
branch assemblies, or leaf assemblies. Preferably, the secondary
branch assemblies are non-uniformly spaced apart from one another
upon each of the branch assemblies, while the branch assemblies are
uniformly spaced upon the trunk. In an expanded state the branch
assemblies extend outwardly at an angle of between about 30 to 90
degrees with respect to the trunk. On the other hand, in a narrow
state the branch assemblies extend outwardly at an angle of between
about 0 to 30 degrees with respect to the trunk.
[0036] The artificial tree according to the invention further
optionally may include any form of tree or leaf type (from conifer,
to deciduous, to palm, etc.) without departing from the scope and
spirit of the present invention, and may also be of any suitable
size, from small (several centimeters--for counter use) to many
meters (even more than twenty-meters (60 feet) or more for use in
large building atriums or for sporting events or entertainment
events.
[0037] The artificial tree according to the invention further
optionally may include in addition to the secondary branches and
foliage, the use of power generation systems that are
interconnected with the operational control systems for the device,
for example, such as the use of solar-cells (crystalline or
amorphous silica, or otherwise) on the `leaf` shapes so that the
proposed artificial tree may generate power sufficient to power
operation of the proposed system. It will be additionally
understood, that the artificial tree according to the invention may
be powered by self-generated power (via solar systems or wind
systems or battery linkages for the same) or by external power (via
a remote power supply or via supplied battery power).
[0038] Optionally, the artificial tree according to the present
invention also provides a universal fit between trunk sections
(i.e., for easy interconnection with other artificial trees).
Consumers do not need to locate any alignment marks between
insertable trunk portions and receivable trunk portions in order to
lock the two portions. In one embodiment of the present invention,
a "blossom" shape allows for as many as six different rotational
configurations for insertion and locking of the insertable trunk
portion to the receivable trunk portion. In another embodiment of
the present invention, a hexagonal shape allows for a similar six
different rotational configurations. In such embodiments, the
consumer can assemble two trunk portions by first resting the
insertable upper portion on top of the receivable lower portion
(with sleeve) and making minor rotations until the insertable upper
portion slides into the receivable lower portion. No visual
alignment is necessary; insertion and locking can be done only on
feel, which can be important when bulky and heavy branches weigh
down each trunk section. In other embodiments, other shapes are
also considered.
[0039] The present invention is directed to an artificial tree
trunk that includes a first trunk portion that may be mechanically
coupled to a second trunk portion via an intermediate securing
sleeve. The first trunk portion is substantially hollow and
generally includes a plurality of branch rings attached to the
outside wall of the trunk and at least one notch located on the end
distal the end secured to a base or stand. The notch and
substantially hollow trunk are able to receive a securing sleeve.
The securing sleeve includes at least one flange of the same shape
as the notch of the first trunk portion such that the sleeve is
insertable and securable to the first trunk portion. The length of
the sleeve is shaped to contour the shape of the second trunk
portion such that the first trunk portion and second trunk portion
make a snug fit and cannot rotate relative to each other. The
second trunk portion is substantially hollow and generally includes
a plurality of branch rings attached to the outside wall of the
trunk. The end of the second trunk portion insertable into the
securing sleeve and first trunk portion is shaped such that, once
inserted, the first trunk portion and second trunk portion make a
secure fit and cannot rotate relative to each other. Each branch
ring on both the first and second trunk portions generally contains
a plurality of veins for receiving individual tree branches. Each
vein contains an aperture for inserting a locking pin to thereby
secure each branch to each vein.
[0040] Optionally, the present invention can include a securing
plug operably couplable to the second trunk portion and a third
trunk portion insertable into the securing plug. In such an
embodiment, the second trunk portion has at least one notch located
on the end distal the end secured to the first trunk portion. The
notch and substantially hollow trunk are able to receive a securing
plug. The securing plug includes at least one flange of the same
shape as the notch of the second trunk portion such that the plug
is insertable and securable to the second trunk portion. The plug
contains an aperture for receiving the third trunk portion. The
third trunk portion generally has branches operably coupled to the
third trunk portion. In another embodiment, the third trunk portion
has a branch ring, square, or any other useful shape that mirrors
the shape of the third trunk portion, with veins and apertures for
securing branches, just as described in the first and second trunk
portions.
[0041] The present invention is not limited to the above-described
embodiments. For example, while the above description recites
first, second, and optionally, third trunk portions, in fact, the
present invention is designed such that it is scalable to both
taller and shorter implementations. In one example, in a room with
20-foot ceilings, a tree having more than three trunk portions may
be desired. Having more trunk portions not only allows the tree to
be built taller, but can aid in assembly and disassembly. In such
an embodiment, a securing sleeve is provided not only at the
junction of the first trunk portion and the second trunk portion,
but also for the second trunk portion and a third trunk portion,
the third trunk portion and a fourth trunk portion, and so on. The
fit provided by the securing sleeves and securing plugs ensures
that the entire tree remains stable and each trunk portion cannot
rotate relative to any other trunk portion. In another example, a
shorter tree having only two trunk portions is considered, whereby
a single securing sleeve at the junction between first and second
trunk portions is needed. Such trees may be useful for rooms with
shorter ceilings, or for placement on tables or stands.
[0042] In another embodiment, the present invention comprises a
locking artificial tree trunk. The tree trunk includes a first
generally cylindrical, hollow trunk portion including an upper end,
the upper end defining a notch; a second generally cylindrical
trunk portion including a body portion, a lower end having an
insertable portion, and an upper end; and a coupling mechanism
including a body portion and an upper portion having a tab, and
defining a channel for receiving the insertable portion of the
lower end of the second trunk portion. The body portion is inserted
substantially into the upper end of the first trunk portion with
the tab of the upper portion aligned with the notch, thereby
preventing rotation of the coupling mechanism within the upper end
of the first trunk portion.
[0043] In another embodiment, the present invention includes an
artificial tree. The tree includes a locking artificial trunk, the
trunk including: a first generally cylindrical, hollow trunk
portion including an upper end, the upper end defining a notch; a
second generally cylindrical trunk portion including a body
portion, a lower end having an insertable portion, and an upper
end; and a coupling mechanism including a body portion and an upper
portion having a tab, and defining a channel for receiving the
insertable portion of the lower end of the second trunk portion.
The sleeve body portion is inserted substantially into the upper
end of the first trunk portion with the tab of the upper portion
aligned with the notch, thereby preventing rotation of the coupling
mechanism within the upper end of the first trunk portion. The tree
also includes a plurality of branch-support rings affixed to the
first and second trunk portions, a plurality of branches connected
to the plurality of branch-support trunk rings, and a base defining
a receiver having an inside diameter larger than an outside
diameter of the lower portion of the first trunk portion such that
the first trunk portion is insertable into the receiver of the
base.
[0044] In yet another embodiment, the present invention comprises a
multi-positional interlocking artificial tree trunk. The tree trunk
includes a first generally cylindrical, hollow trunk portion
including an upper end, a second generally cylindrical trunk
portion including a lower end having an insertable portion, and an
upper end. The trunk also includes a coupling mechanism inserted
substantially into the upper end of the first trunk portion, the
coupling mechanism including a body portion and an upper portion,
and defining a channel for receiving the insertable portion of the
lower end of the second trunk portion. The insertable portion forms
an insertable, non-circular cross-section and the channel defines a
non-circular channel cross-section that is complementary to, and
circumferentially larger than, the insertable cross-section such
that the insertable portion is insertable into the channel to
secure the first trunk portion to the coupling mechanism in one of
a plurality of relative rotational positions, thereby preventing
rotation of the second trunk portion relative to the coupling
mechanism.
[0045] The present invention further provides an artificial tree
apparatus having a plurality of tree trunk segments that couple
together to provide electrical power to receptacles on each of the
segments. The apparatus includes a first trunk segment having a
cylindrical body with an outside wall and an internal cavity. The
first trunk segment has an upper portion and lower portion, the
upper portion having an outside diameter, a raised decent on the
outside wall, and an end face bearing an electrical connector such
as a socket. A second trunk segment also has a cylindrical body
with an outside wall and an internal cavity, and also has an upper
portion and lower portion, this lower portion having an inside
diameter marginally greater than the first trunk segment upper
portion outside diameter so that the first trunk segment upper
portion can slide into and engage the second trunk segment lower
portion. The second trunk segment lower portion has a notch or
guide slot in the outside wall, and a recessed end face bearing an
electrical connector such as a plug. An electrical line is
connected to the first trunk segment electrical connector, such
that when the first trunk segment upper portion is brought into
juxtaposition with the second trunk segment lower portion, the
detent on the first trunk segment upper portion can be brought into
alignment with and slidably engage with the guide slot on the
second trunk segment lower portion to permit connection of the
first trunk segment electrical connector (socket) with the second
trunk segment electrical connector (plug).
[0046] The recessed location of the plug on the second segment
protects the plug prongs, and connection with the corresponding
socket on the first segment is only possible when the detent on the
first segment has been aligned with the guide slot on the second
segment. That is, the plug and socket are positioned within their
respective trunk segments so that not until the detent and guide
slot on the segments are properly aligned are the plug prongs and
the socket holes capable of connection.
[0047] The cylindrical shapes of the corresponding tree trunk
segments facilitates connection of the segments, as juxtaposition
and initial insertion of the first (male) segment into the second
(female) segment can be achieved at any angular position, that is,
the smaller diameter male portion can freely rotate within the
larger diameter female portion when they are first inserted
together. However, by locating the raised detent a short distance
(offset) from the socket on the end face, complete connection of
the plug prongs with the socket is prevented until the two segments
are rotated relative to one another until the guide slot and detent
are properly aligned, ensuring that the plug prongs will then slide
straight into the socket holes.
[0048] The artificial tree apparatus of the present invention thus
provides an improved coupling arrangement for the trunk portions of
an artificial tree in which each section, besides connecting
easily, carries current and any other important electrical
information or commands via the tree column. Each section is thus
electrically contained, meaning that the lighting source (string),
whether it be incandescent or LED plug in strings (AC) or strictly
DC operated LED strings, connects/plugs into its corresponding
section of the column (trunk) of the tree. This design will also
work for unlit trees (where the consumer strings the tree) but is
mostly considered for pre-lit trees.
[0049] Each section of the tree couples with its connecting
partner, thus delivering the current through the column of the tree
from a connector/controller/plug that plugs into an AC socket. This
makes assembly and disassembly much easier for the user. No need to
plug individual strings together or plug strings from one section
of tree to another or run long electrical leaders to other areas of
the tree. To assemble, just couple each section together and turn
it on. Each section of column couples together mechanically and
electrically. To disassemble, just fold up the branches up and
de-couple each section.
[0050] One embodiment of the inventive apparatus includes a DC
motor in the base that allows the tree to rotate. A wireless remote
control allows the user to turn the lights on and off and turn the
rotation motor on and off via the power/controller box (power
transformer/light controller/tree rotation controller box). A
tapered top section perfectly connects with a tree topper socket. A
DC version may be different in that it has DC socket connections in
the column of the tree instead of AC sockets. On this version the
voltage is reduced at the controller box plugged in at the wall so
all voltage beyond that point is low voltage. The controller box
may contain a voice activated light controller, and in the DC
version the user may be able to turn the tree lights on and off via
a special touch sensor ornament (e.g., a metal snowflake) that is
permanently attached to the tree.
[0051] In one embodiment, small DC connector interfaces are placed
on the middle column of the tree (trunk). This enables pre lit
trees that are lit with low voltage LED strings that connect
directly into the middle column of the tree. If one string goes out
the user can easily identify the rogue string, unplug it and
replace it with a working string. Gone are the days of strings all
connected together in a confusing mess. The coupling system between
each section of tree in the DC version may be different than the AC
version. These extra connectors allow for additional information
transfer from the controller/voltage box to the tree; e.g., a touch
activated on/off switch built into the tree, lighting effects,
etc.
[0052] The top section of the middle column may have one or more AC
type plug; this allows the user to plug some already existing low
voltage device, such as an illuminated tree topper into the tree
without having to run an extension cord down to the floor and into
an outlet.
[0053] It is therefore an aspect of the present invention to
provide a new and improved artificial tree.
[0054] It is another aspect of the present invention to provide a
new and improved artificial illuminated tree that is easily
assembled and disassembled.
[0055] A further aspect or feature of the present invention is a
new and improved artificial tree that carries current and any other
important electrical information or commands via the tree
column.
[0056] An even further aspect of the present invention is to
provide a novel artificial tree where the lighting source plugs
into its corresponding section of the column (trunk) of the
tree.
[0057] It is accordingly an aspect of the present invention to
provide an artificial tree which can be easily erected from a
collapsed compact storage state.
[0058] It is a further aspect of this invention to provide an
artificial tree as in the foregoing aspects whose branches are
sufficient in number and distribution to provide a tree having a
full and uniform appearance.
[0059] It is another aspect of the present invention to provide an
artificial tree of the aforesaid nature of rugged and durable
construction amenable to low cost manufacture.
[0060] The above and other beneficial aspects and advantages are
accomplished in accordance with the present invention by an
artificial tree comprising an elongated rigid trunk having upper
and lower extremities, a base adapted to engage the lower extremity
in a manner to support the trunk in a vertically upright
disposition in the erected state of the tree, and a series of
branch assemblies positioned upon the trunk, each assembly
comprising an upper collar slidably disposed upon the trunk, a
number of first lever arms uniformly disposed about the trunk,
having upper extremities pivotably attached to the upper collar in
a manner permitting movement of the arms in vertical paths, the
arms being downwardly angled away from the trunk to lowermost
extremities, a lower collar affixed to the trunk, a second lever
arm associated with each first lever arm in vertically coplanar
relationship, each second lever arm having a lower extremity
pivotably attached to the lower collar in a manner permitting
movement of the arm in a vertical path, the second arms being
upwardly angled away from the trunk to an uppermost extremity which
pivotably engages the associated first lever arm, an elongated
branch element pivotably attached to the lowermost extremity of
each first lever arm and extending between an outermost extremity
and an innermost extremity located below the first lever arm, and a
third lever arm pivotably interconnected to each second lever arm
and the innermost extremity of the associated branch element to
form a parallelogram having pivotal movement at its four apexes,
whereby sliding movement of the upper collar downwardly upon the
trunk toward the lower collar causes the branch elements to be
laterally displaced from the trunk and upwardly angled therefrom to
produce the erected state of the tree, and opposite movement of the
upper collar causes the first, second and third lever arms and
branch elements to be drawn close to the trunk and in substantially
coaxial alignment therewith, producing the storage state of the
tree, the dimensions of each branch assembly of the series being
such that the outermost extremities of the branch elements in the
erected state extend further from the trunk in descending the
members of the series.
[0061] In preferred embodiments of the invention, the trunk is of
circular cylindrical configuration. There is preferably a plurality
of branch assemblies uniformly spaced upon the trunk. Each branch
assembly preferably has numerous secondary branch elements or leaf
elements. The secondary branch elements may have the form and
appearance of the final branches of the tree, or they may merely
constitute the support for imitative tree branch material. In the
erected state, the branch elements extend upwardly at an angle of
between about 30 to 90 degrees with respect to the trunk, while in
the narrow or retracted state the branch elements extend upwardly
at an angle of between about 0 to 30 degrees with respect to the
trunk.
[0062] Other novel features which are characteristic of the
invention, as to organization and method of operation, together
with further objects and advantages thereof will be better
understood from the following description considered in connection
with the accompanying drawings, in which preferred embodiments of
the invention are illustrated by way of example. It is to be

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0081] As required, a detailed illustrative embodiment of the
present invention is disclosed herein. However, techniques,
systems, compositions and operating structures in accordance with
the present invention may be embodied in a wide variety of sizes,
shapes, forms and modes, some of which may be quite different from
those in the disclosed embodiment. Consequently, the specific
structural and functional details disclosed herein are merely
representative, yet in that regard, they are deemed to afford the
best embodiment for purposes of disclosure and to provide a basis
for the claims herein which define the scope of the present
invention.
[0082] Reference will now be made in detail to several embodiments
of the invention that are illustrated in the accompanying drawings.
Wherever possible, same or similar reference numerals are used in
the drawings and the description to refer to the same or like parts
or steps. The drawings are in simplified form and are not to
precise scale. For purposes of convenience and clarity only,
directional terms, such as top, bottom, up, down, over, above,
below, etc., or motional terms, such as forward, back, sideways,
transverse, etc. may be used with respect to the drawings. These
and similar directional terms should not be construed to limit the
scope of the invention in any manner.
[0083] Referring first to FIGS. 1-7 where like reference numerals
refer to like components in the various views, there is illustrated
therein a new and improved artificial tree apparatus 10. Initially,
FIG. 1 shows a front view of the portable and retractable
artificial tree 10 according to the preferred embodiment of the
present invention, illustrating the base housing unit 2, control
mechanism 12, the tree trunk 14 and the branch assemblies 16. While
FIG. 1 shows the artificial tree apparatus 10 of the invention as
assembled but without secondary branch assemblies or leaf
assemblies (see FIGS. 4-5 and 9), as shown, the tree 10 includes a
single tree trunk 14 or may comprise a plurality of tree trunk
segments, each preferably carrying one or more branch supports 22
for connection to artificial branch assemblies 16, and one or more
optional electrical sockets (not shown, see FIG. 8). The lower most
part of tree trunk 14 may also include a fuse and/or fuse box or
holder positioned adjacent tree stand or base unit 2.
[0084] Artificial tree assembly 10 includes a trunk portion 14. In
some embodiments, artificial tree trunk 2 may include a plurality
of trunk portions, such as first and second trunk portions 14a, 14b
shown in FIG. 10, and may be secured by coupling mechanism. When
tree trunk 10 is assembled, as depicted, trunk portion 14 or
portions 14a, 14b are configured along a common vertical axis and
held in a general vertical orientation. To maintain the general
vertical orientation, a lower end of trunk portion 14 is insertable
into an opening 6 in the cover 4 of base or stand portion 2 that
supports the entire tree assembly 10. Such a base 2 preferably
includes a receiver, such as a channel or other opening, as
understood by those skilled-in-the-art, for receiving a bottom
portion of trunk portion 14, the receiver having an inside diameter
equal to or slightly larger than, an outside diameter of the bottom
portion of trunk portion 14. As seen in FIGS. 1-2, base unit 2
further comprises a branch control mechanism 12 preferably
positioned in a secure manner on an underside of the cover 4 of
base unit 2. Control mechanism 12 may be connected to a computer or
other known control device for instructing the control mechanism 12
to move the branch assemblies 16 and/or secondary branch assemblies
26 having leaves 26 thereon.
[0085] As depicted in FIG. 7, shown is a partial cross-sectional
view of the artificial tree 10 in a substantially vertical position
with respect to the base housing unit 2, the branch assemblies 16
extending from the substantially vertical tree trunk 14, and the
secondary branch or leaf assemblies 26 extending from the branch
assemblies 16. Also shown are the lever arms 18, 28, 36 connecting
the branch 16 and leaf 26 assemblies to the control mechanism 12
inside the base unit 2. As seen, preferably, control mechanism 12
controls one or more lever arms 36 positioned coaxial within trunk
14, and which are integrally connected with each of the branch
assemblies 16 to control the lateral, vertical, rotational, and/or
angular movement thereof with respect to the trunk 14. As seen in
FIG. 6, control mechanism 12 (shown earlier) can enable lateral 34
or angular 32 movement of the branch assemblies 16.
[0086] It will be recognized that control mechanism 12 may include
a plurality of operatively dependent components understood by those
of skill in the art but not shown here. Included optionally would
be a mechanical controller system for movement control driven by a
computerized process controller (computer, memory function, input
program and controllers, etc.), an input module (for receiving
wired, wireless (internet, hand held, etc.), and other control
signals) and for driving the mechanical controller system according
to the memory input or the received control signals.
[0087] The trunk portion 14, as depicted, preferably comprises a
generally cylindrical, hollow structure including a lower end, an
upper end, outer wall, and a plurality of branch-support interfaces
22. The lower end of the trunk portion 14 may be tapered or not
tapered for ease of coupling to the cover 4 of the base unit or
stand portion 2. A plurality of branch-support rings or coupling
members 22 may include multiple branch receivers extending
outwardly and away from first trunk portion 14. In some
embodiments, the branch coupling members 22 define a channel for
receiving a primary branch assembly 16. Each branch generally
includes primary branch extension 216 and may also include multiple
secondary branch extensions 26 extending away from branch extension
16. The branch assemblies 16 are preferably connected to trunk
portion 14 at a branch receiver 22 at various locations along the
trunk 14. Primary branch assemblies 16 may be bent or otherwise
formed to define a loop or circular opening such that primary
branch assembly 16 may be secured to branch receiver 22 by way of
threading or a pin extending through branch receiver 22 and
connected to the lever arm 18 or 36 within trunk 14 and connected
to and controlled by mechanism 12. In this way, a branch assembly
16 may be allowed to pivot, extend, retract, or otherwise move with
respect to the trunk 14 to expand or retract the branches of the
tree 10.
[0088] It will also be appreciated, in an alternative embodiment
that branch assemblies 16 may alternatively contain
power-generation means such as solar arrays, optionally in the form
of leaf-shapes that may generate power for the proposed controller
mechanism 12 or for other uses to operate and initiate light
sequences, communication systems (noting on-off, pivoting,
opening/closing, etc.).
[0089] In the embodiment of the invention depicted in FIGS. 4-5,
shown is a side elevation view of the branch assemblies 16 for use
on the artificial tree 10 according to the preferred embodiment of
the present invention. Also shown are secondary branch assemblies
or leaf assemblies 26 extending from a branch assembly which
extends from the tree trunk 14. As seen in FIG. 5, internal lever
arms 28 are provided for controlling the secondary branch assembly
26 and extend coaxially within branch assemblies 16 to interconnect
with leaves 24 or other choice foliage (and optionally solar arrays
if needed) or end covering via secondary branch assemblies 26 at
interface 30. Lever arm 28 within branch assembly 16 is then
connected at one end to central lever arm 18 positioned coaxially
within tree trunk 14, as seen in FIG. 7, which in turn is connected
to control mechanism 12. Such interconnection between the branch
assemblies 16, 26 and the lever arms 18, 28 allows control
mechanism 12 to control the positioning and movement of the various
branch assemblies 16, 26 throughout the tree assembly 10. If the
user desires the tree 10 to be in its fully extended or expanded
state that control mechanism will direct such movement of the
branch assemblies.
[0090] Conversely, the user can direct the control mechanism to
position the tree 10 in its fully retracted state. Such
instructions may be provided manually by a user through, for
example, a wired or wireless interface, including without
limitation, a tablet, a computer, smart phone device, etc., or such
instructions may be provided automatically via a pre-programming of
the alternative process controller (see above) if certain
conditions are met. For example, a sensor (in communication with
the process controller) may be employed on the tree 10 to detect an
increase in wind conditions thereby informing control mechanism 12
to retract certain or all of the branch assemblies 16, 26 so as to
minimize potential damage to the tree 10 due to high winds. Other
weather related conditions, i.e., rain, snow, heat, cold, etc.,
received via the sensor array to a controlling mechanism may also
be used to direct control mechanism 12 to reposition any or all of
the branch assemblies 16, 26. Also, it is disclosed that control
mechanism may be configured to control all branch assemblies 16, 26
as one single unit, or may be configured to control each separate
branch assembly 16, 26 on its own separate and apart from control
of each other branch assembly 16, 26. It is also adaptively
envisioned that the control mechanism and system may be configured
to orient any solar cell array features in a preferred
solar-orientation for optimal energy generation.
[0091] Referring next to FIGS. 8-10, wherein like reference
numerals refer to like components in the various views, there is
illustrated therein a new and improved artificial tree apparatus
100/200. FIG. 8 shows a front elevation view of the artificial tree
assembly 100 positioned on a base unit 102 according to an
alternative embodiment of the present invention, without the branch
assemblies or leaf assemblies installed. FIG. 9 shows a front
elevation view of an artificial tree assembly 200 on a base unit
202 according to yet an alternative embodiment of the present
invention, with some branch assemblies 216 and leaf assemblies 226
installed thereon. While FIG. 8 shows the artificial tree apparatus
100 of this invention as assembled but without branches assemblies,
as shown, the tree 100 includes a single tree trunk 114 or may
comprise a plurality of tree trunk segments 114, each preferably
carrying one or more branch supports 122 for connection to
artificial branches (not shown here), and one or more optional
electrical sockets 106. The lower most part of tree trunk 114 may
also include a fuse and/or fuse box or holder positioned adjacent
tree stand or base unit 102.
[0092] Turning now to FIG. 9, an alternative embodiment of an
artificial tree trunk 200 of the present invention is depicted.
Artificial tree trunk 200 includes first trunk portion 214. In some
embodiments, artificial tree trunk 200 may include a plurality of
trunk portions, such as first and second trunk portions 14a, 14b
shown in FIG. 10, and may be secured by coupling mechanism. When
tree trunk 200 is assembled, as depicted, trunk portion 214 or
portions 14a, 14b are aligned along a common vertical axis and held
in a general vertical orientation. To maintain the general vertical
orientation, a lower end of trunk portion 214 is insertable into a
base or stand portion 202 that supports the entire tree assembly
200. Such a base 202 preferably includes a receiver, such as a
channel or other opening, as understood by those
skilled-in-the-art, for receiving a bottom portion of trunk portion
214, the receiver having an inside diameter equal to or slightly
larger than, an outside diameter of the bottom portion of trunk
portion 214.
[0093] The trunk portion 214 as depicted comprises a generally
cylindrical, hollow structure including a trunk portion body having
a lower end, an upper end, outer wall, and one or more
branch-support interfaces 222. The lower end of the trunk portion
214 may be tapered or not tapered for ease of coupling to an
appropriate base or stand portion 202. A plurality of
branch-support rings 222 include multiple branch receivers
extending outwardly and away from first trunk portion 214. In some
embodiments, the branch receivers define a channel for receiving a
primary branch extension 216 of a branch 224. Each branch 224
generally includes primary branch extension 216 and may also
include multiple secondary branch extensions 226 extending away
from branch extension 216. Branches 224 are connected to trunk
portion 214 at a branch receiver 222 a various locations along the
trunk 214. Primary branch extensions 216 of branches 224 may be
bent or otherwise formed to define a loop or circular opening such
that primary branch extension 216 of branch 224 may be secured to
branch receiver 222 by way of threading or a pin extending through
branch receiver 222 and the loop formed at trunk-end branch 224. In
this way, a branch 224 may be allowed to pivot, extend, retract, or
otherwise move with respect to the trunk 214 to expand or retract
the branches 224 of the tree 200.
[0094] Referring to FIG. 10, shown is a perspective view of an
embodiment of two interconnecting tubular components 14a, 14b for
use as the artificial tree trunk assembly 100/200 in accordance
with an alternative embodiment of the present invention. More
specifically, depicted is the coupling of two trunk segments 14a,
14b. First trunk segment 14a has a generally cylindrical body with
an outer wall 17 and an inner cavity 19. The first trunk segment
14a has an upper end and lower end, the upper end having a first
outside diameter, and the lower end having a second outside
diameter. Similarly, second trunk segment 14b has a generally
cylindrical body with an outer wall 17 and an inner cavity 19. The
second trunk segment 14b has an upper end and lower end, the upper
end having a first outside diameter, and the lower end having a
second outside diameter. Generally, the second outside diameter of
the trunk segments 14a, 14b is narrower than the first outside
diameter of the trunk segments 14a, 14b such that the lower end of
the first trunk segment 14a can slide into and engage with the
upper end of the second trunk segment 14b so as to be position
partially in inner cavity 17 of the second trunk segment 14b. The
upper end of the second trunk segment 14b preferably has a notch or
guide slot 13 in the outside wall 17 for engaging the lower end of
the first trunk segment 14a. Optionally, an electrical line may be
connected to the first trunk segment via electrical connectors (see
FIG. 8), such that when the first trunk segment upper portion 14a
is brought into juxtaposition with the second trunk segment lower
portion 16b, the electrical connectors can be brought into
alignment to permit connection thereof.
[0095] Turning lastly to FIGS. 11-14, shown are illustrations of
the preferred embodiment of the portable and retractable artificial
tree 10 in accordance with the present invention. As shown,
depicted is the tree trunk 14 in a substantially vertical position
with respect to the base housing unit 2 and the branch assemblies
16 extending from the substantially vertical tree trunk 14, each
branch assembly 16 further having secondary branch or leaf
assemblies 26 extending therefrom. As illustrated in FIG. 11, the
branch assemblies 16 may be in a retracted or partially retracted
position, or as seen in FIG. 12, the branch assemblies 16 may be in
an expanded or fully expanded position. Control mechanism 12, as
seen in FIGS. 13-14, is preferably positioned within base unit 2,
optionally positioned on the underside of cover 4 of the base unit
2, such that control mechanism is interconnected with lever arm(s)
18 which extends upward through an opening 6 in cover 4 to extend
longitudinally within and substantially coaxial with tree trunk 14
to further interconnect with branch assemblies 16, as described and
shown herein.
[0096] It should be additionally understood by those of skill in
the art having studied the disclosure herein that the proposed
system may be provided in alternative and adaptive sizes. For
example such trunks and system may be of a relatively small size,
for example several centimeters high, or in a relatively large
size, for example twenty-meters or more in height, all without
departing from the scope and spirit of the present invention. This
allows the present invention to be used for smaller offices, for
homes, for large business-building atriums, for farming and other
commercial uses, all within the scope of the present invention. As
such, it will be recognized that the proposed invention may be
positioned by hand (smaller size), by a user-vehicle such as a
`fork-truck` (for medium sizes), by larger trucks and even rail or
crane delivery (for very large sizes), all within the scope and
spirit of the present invention. It will also be understood, that
the proposed inventive system may be used for an array of user
options, from seasonal displays, to farming, to other industrial
uses, and to uses intended to be substantially permanent (e.g. in
buildings, for road-sound abatement, and for other needs that may
last for many months or years).
[0097] Additionally, it will be recognized that each of the limbs,
leaves, stalks, and arms noted herein may be manipulated for motion
in the directions noted (in/out, up/down, etc.) and at a rate
(speed of motion) that may be controlled according to a computer
processor controller (not shown) that may be liked with and
programmed for operation with the driving devices and power
controls herein. It will be recognized that the computer process
controller will contain all required features and functions to
operate as a controlling processor (memory, capacitors,
input/output ports, receiving and transmitting antenna,
communication ports, stored controlling code, etc.) for such
devices as may be found within those of skill in the art. Such
computer processor controllers may be known to those of skill in
the arts of consumer products manufacture.
[0098] In the claims, means or step-plus-function clauses are
intended to cover the structures described or suggested herein as
performing the recited function and not only structural equivalents
but also equivalent structures. Thus, for example, although a nail,
a screw, and a bolt may not be structural equivalents in that a
nail relies on friction between a wooden part and a cylindrical
surface, a screw's helical surface positively engages the wooden
part, and a bolt's head and nut compress opposite sides of a wooden
part, in the environment of fastening wooden parts, a nail, a
screw, and a bolt may be readily understood by those skilled in the
art as equivalent structures.
[0099] Having described at least one of the preferred embodiments
of the present invention with reference to the accompanying
drawings sufficient to enable one of ordinary skill in the art to
practice the invention, and to provide the best mode of practicing
the invention presently contemplated by the inventor, it is to be
understood that such embodiments are merely exemplary and that the
invention is not limited to those precise embodiments, and that
various changes, modifications, and adaptations may be effected
therein by one skilled in the art without departing from the scope
or spirit of the invention as defined in the appended claims.
Accordingly, the disclosed embodiments are not mutually exclusive
combinations of features; rather, the invention may comprise a
combination of different individual features selected from
different individual embodiments, as understood by persons of
ordinary skill in the art. The scope of the invention, therefore,
shall be defined solely by the appended claims.
[0100] Further, while there is provided herein a full and complete
disclosure of the preferred embodiments of this invention, it is
not desired to limit the invention to the exact construction,
dimensional relationships, and operation shown and described.
Various modifications, alternative constructions, changes and
equivalents will readily occur to those skilled in the art and may
be employed, as suitable, without departing from the true spirit
and scope of the invention. Such changes might involve alternative
materials, components, structural arrangements, sizes, shapes,
forms, functions, operational features or the like, it will be
apparent to those of skill in the art that numerous changes may be
made in such details without departing from the spirit and the
principles of the invention. It should be appreciated that the
present invention is capable of being embodied in other forms
without departing from its essential characteristics.
