Description:
BACKGROUND OF THE INVENTION 
     1. Field 
     The present invention relates to systems, apparatuses and methods for assembling items made of fabric or other sheet-based materials such as plastics, fur, artificial fur, canvas, etc. In particular, the invention relates to forming plush replicas of plants, artificial plants, animals, mythical creatures, mascots and the like. 
     2. Related Art 
     Various fuzzy, plush, stuffed and fabric-based items have been created for many decades. One popular item in the early twentieth century was the teddy bear: a soft and stuffed toy sewn with fabric with a thick pile and formed to look like a bear. It was named after U.S. President Theodore “Teddy” Roosevelt, Jr. The teddy bear has been the subject of story, song and film. Further, teddy bears and other plush animals and other forms have become popular gifts for children and adults alike. Teddy bears and other cute creatures are often given to signify love, congratulations or sympathy. These plush creations have become part of the American culture and can be found in many online and brick-and-mortar retail outlets throughout the world. 
     American culture also has come to embrace aspects of the  Cannabis  sub-culture. A significant minority of America celebrates a small genre of films known as stoner films and is responsible for introducing pot paraphernalia and slang into the mainstream lexicography. In the U.S., the  Cannabis  sub-culture has its own celebrities, magazines, holidays and the like. Even in some states,  Cannabis  possession has become legalized. 
     It is at the intersection of the plush toy and  Cannabis  culture that the instant invention has its genesis. Improved systems, apparatuses and methods are described herein for creating and assembling plush items. One item illustrated is a replica of a  Cannabis  plant, an item familiar to those of the  Cannabis  culture. However, the teachings are not so limited, and the teachings from the invention described herein may be used in a variety of arts. 
     SUMMARY 
     Embodiments and techniques described herein include improved systems, apparatuses and methods for creating components of plush items. Illustrated is construction of components of a replica of a  Cannabis  plant and for assembling the components into a finished item. 
     According to a first illustration, a square of plush fabric is folded and stitched to form a plush square with four plush subsections. Each subsection (e.g., nub, bulb or bud) forms the buds emanating from a central stock. Several squares are created. Ornamental strings are attached to the corners of the squares. Three squares are assembled into a triplet. Several triplets are formed. A stem, core or stock is formed by coating a tube or pipe. The tube or pipe may be made of an expanded polypropylene foam or other flexible material. The triplets are assembled onto the core or stock by nesting one triplet inside of another. The triplets are anchored to the core. A finished product includes these and other steps including making aesthetic adjustments as necessary to obtain a final product with desired properties and characteristics.

     DETAILED DESCRIPTION 
     Embodiments and techniques described herein include improved systems, apparatuses and methods for creating components of plush items. Illustrated is construction of components of a replica of a  Cannabis  plant and for assembling the components into a finished item. 
     Briefly, the following is a first illustration of a method of assembly of an illustrative plush item. A square of plush fabric is folded and stitched to form a plush square with four plush subsections. Each subsection (e.g., nub, bulb or bud) forms the buds emanating from a separately created central stock or stem. Several squares are created. Ornamental strings are attached to the corners of the squares. Three squares are assembled into a triplet. Several triplets are formed. The triplets are assembled onto a core or stock by nesting one triplet inside of another and anchoring the triplets to stem. A finished product may include other steps including making aesthetic adjustments as necessary to obtain a final product with desired properties and characteristics. 
     A series of figures are presented and described. The following describes a series of figures that illustrate the process for making a plush item.  FIG. 1  illustrates an overhead view of a piece of cloth according to a first embodiment. Throughout this document, the piece of cloth is generally referenced as item  10 . The piece of cloth is preferably made from an industrially produced fabric but may be formed from hand-made processes such as knitting and the like. With reference to  FIG. 1 , a piece of cloth  10  includes a first generally planar side  1  and a second generally planar side  2 . The piece of cloth  10  also has at least a first edge or dimension  3  and a second edge or dimension  4 . While a square starting shape is shown for the cloth  10 , other starting shapes are possible such as triangles, pentagons, hexagons, etc. The starting shape and subsequent treatment (e.g., folding, stitching and assembly) determine many of the characteristics of the final plush item. With reference to  FIG. 1 , the first side  1  may include a texture  5  or other elements that are distinct from a texture or other elements of the second side  2 . 
     The starting materials for a finished, small plush  cannabis  pillow include six squares of green fabric that are approximately one-foot by one-foot in dimension at the start such as shown in  FIG. 1 . Further, the starting materials include: 24 four-inch lengths of copper-colored embroidery floss, fabric leaves of about two inches in their longest (length) dimension, one 12-inch by 1⅜ inch polyvinyl chloride (PVC) insulator foam piece, green nylon thread, and polyester stuffing. 
     The starting materials for a large plush  cannabis  pillow include 12 squares of green fabric that are approximately one-foot by one-foot in dimension. According to a first illustrative example, the cloth  10  is made of a green fabric having a thick and soft pile. One such fabric is a commercially available minky rose cuddle olive (“MRCO”) fabric that forms a green color reminiscent of a  Cannabis  plant. The MRCO fabric has a thick pile which lends itself to a soft or feathery tactile sensation. The starting materials also include 48 four-inch lengths of copper-colored embroidery floss, and 12 fabric leaves of about two inches in their longest (length) dimension. The starting materials also include one 24-inch by 1⅜ inch polyvinyl chloride (PVC) insulator foam. Green nylon thread is used along with a polyester stuffing used for stuffing certain assembled pieces as described in more detail herein. 
       FIG. 2  illustrates an overhead view of a partially assembled, partially-stitched (inside out) pillowed component made from the piece of cloth  10  shown in  FIG. 1 . With reference to  FIG. 2 , one of the four corners has been left unfolded.  FIG. 2  illustrates how a cloth  10  can be stitched. A back side or second side  2  with a less feathery or unfinished texture  9  is visible. Preferably, each corner is folded toward a center location  11 . Each corner or folded portion includes a part of a first dimension  3  and a part of second dimension  4 . The texture  5  of the first side  1  is visible on the unfolded corner. Starting and ending stitch indicators  6  define the ends of the stitch path  7  that can be taken when stitching together the edges  3 ,  4  of the cloth  10 . Only a single stitch path  7  is shown for sake of simplicity of illustration in  FIG. 2 . Ornamental strings or threads  8  are added to each corner of the square  10 . Any of various kinds of ornamentation can be added during sewing and assembly of the plush item. According to one implementation, a copper-colored embroidery floss is used for the strings  8 . However, white, green or red strings  8  may be used. 
       FIG. 3  illustrates the partially sewn square  15  shown in  FIG. 2  in a first sewing configuration. With reference to  FIG. 3 , a sewing person would match up opposing edges  3  by folding the cloth  10  along a first folding line  7 A and would sew along second edges  4  as indicated by the stitch paths  7 . For example, sewing could start and end at the indicated stitch indicators  6 . In this way, two of the four stitch paths  7  could be easily and rapidly accomplished. The other two of four stitching paths (not shown) could be accomplished by folding the cloth  10  along a second sewing folding line  7 B indicated by the dashed line. Note that stitching is preferably made up to the folding line  7 A, but stitching is avoided near the first edges  3  as indicated by the regions  6 A. These regions  6 A provide a means (as shown and described with relation to other figures herein) for inserting stuffing into the substantially enclosed square  15 . The unfinished texture  9  of the second side is visible on the outside of the second side  2 . According to an illustrative technique, any stitching, when the square  15  is finished, would be folded toward the inside of the finished square  15  and thus the seam sewn along line  7  would be hidden from view. The texture  5  of side  1  is visible for sake of illustration to show that portions of side  1  are folded to the inside of the square  15  shown in  FIG. 3 . 
       FIG. 4  illustrates an overhead view of a fully assembled pillow or square  15  made from the piece of cloth shown in  FIG. 1 . The texture  5  of side  1  is visible over the surface of the square  15 . The texture  5  covers the exterior of the square  15  on the outside sides  1 ,  1 A. Threads  8  have been added to each of the corners. Stitching to attach the threads  8  would be folded inside the square  15  when the square  15  is turned right-side out—as shown in  FIG. 4 . The square  15  has been stuffed with stuffing such as a non-combustible, commercially reasonable stuffing, padding or batting. Such stuffing could be a natural or artificial stuffing. Examples of such stuffing include: foam, filament based stuffing, wool, feathers, polystyrene-based pellets, cloth pieces and beans. Preferably, the stuffing is something soft and at least somewhat resilient. Due to stitching indicated in  FIG. 2  (along paths  7 ), a finished stitching  13  separates the square  15  into four quadrants, nubs, bulbs or buds indicated by roman numerals I, II, III, and IV. The batting is added to each quadrant of the square  15  via openings near the center  11 . After being filled, the openings near the center  11  may be sewn shut as indicated by the stitching points  12 . At this point in time during the assembly process, the square  15  is formed with a substantially linear first side  3  and a substantially linear second side  4 . 
       FIG. 5  illustrates a perspective view of a fully assembled pillow square  15  made from the cloth shown in  FIG. 1 . A distinct texture  5  is visible on the exterior or exposed sides  1 ,  1 A. The quadrants  14  are separated by the finished stitching  13 . The center is visible at an intersection of the quadrants  14 . Threads  8  are attached at the exterior corners of the quadrants  14 . Several of the pillow squares  15  are needed before continuing with further steps in the assembly—shown in  FIGS. 6-9 . 
       FIG. 6  illustrates a partially assembled “triplet” of squares  15  in a first configuration according to a first embodiment. The first configuration is a preliminary configuration in the assembly process. The first embodiment is shown for sake of illustration in forming the components of a finished pillow. Each of the squares  15 A,  15 B and  15 C includes finished stitching  13  that divides each square into four quadrants or buds  14 . The finished stitching  13  may intersect at a middle region  11  of each square  15 . Accordingly, with each assembled triplet, twelve buds  14  are formed and added to a finished pillow. The quadrants  14  are shown as being of substantially equal size and shape but such is not required. Further, each square may be divided into other numbers or shapes of buds. Strings or filaments  8  are visible in the outer corner of each quadrant  14 . 
     With reference to  FIG. 6 , a first square  15 A is attached to a second square  15 B at stitch points  16 . The stitch points  16  may indicate single points of assembly if assembly is accomplished with snaps, rivets, plastic staples, or some other single-point attachment means. Alternatively, stitch points  16  indicate generally an area of bar tacking stitching  17  where stitching can be made to join adjacent squares together and reinforce the fabric at these points of contact. The bar tacking  17  is preferably done over the top or near a portion of the finished stitching  13  which allows for minimal disruption of the shape and other characteristics of the affected quadrants  14 . The first square  15 A is attached or sewn at a first area  16  to a first area  16  of the second square  15 B. The first square  15 A is also attached to a third square  15 C at a region  17 . The second square  15 B is also attached to the third square  15 C at a region  17 . Thus, each square  15  is attached at a point or region to each of its two neighboring squares. For sake of illustration, a gap  18  is shown between adjacent squares  15 B,  15 C before these adjacent squares  15 B,  15 C are connected to each other. 
       FIG. 7  illustrates a partially assembled triplet lying substantially flat and in a second configuration after three connections or bar tackings  17  have been completed between the squares  15 A,  15 B and  15 C. From this configuration, three more connections or bar tackings will be made. Generally herein, a triplet of squares  15  is referred to as assembly  20  where adjacent squares  15  have been attached to each other. With reference to  FIG. 7 , a second set of connections  18  are to be made which connect two squares  15  together. Pairs of squares  15  are again attached to each other at or near a portion of a finished seam  13  so as to facilitate formation of bulbous buds  14 . A first pair of bar tackings  18 A is indicated in the first square  15 A and the second square  15 B with an open circle. A second pair of bar tackings  18 B is indicated in the first square  15 A and the third square  15 C with an open square. A third pair of bar tackings  18 C is indicated in the second square  15 B and the third square  15 C with an open triangle. The center  11  of each square  15 A,  15 B and  15 C serve as points by which to manipulate each square to bend and fold so that appropriate bar tack regions may be mated together and stitched or attached. According to illustrative examples, the squares may be attached at the bar tacking regions  17  by stitching made by a sewing machine, or by snaps, rivets, plastic fasteners, metal fasteners, etc. 
       FIG. 8  illustrates a partially assembled triplet  20  in a third configuration after four connections or bar stitchings have been made between the pillows. The first three connections or bar stitching  17  have been made as illustrated in  FIGS. 6-7 . Further, a first of three connections or bar stitchings  18  have been made—the positions being indicated in  FIG. 7 . With reference to  FIG. 8 , a first bar stitching or connection  18 A has been completed between the first square  15 A and the second square  15 B. Next in time, two remaining bar stitchings  18 B and  18 C are to be made. In total, six bar stitchings  17 ,  18  are to be made in the assembled triplet  20 —shown in  FIG. 9 . The texture  5  is visible on each quadrant or bud  14 . The center  11  of each square  15 A,  15 B and  15 C are visible and may serve as places by which to manipulate each square; that is, to bend and fold the squares  15 A,  15 B and  15 C so that appropriate bar tack or sewing or connecting regions may be mated or connected together. Such connections are preferably made as permanent as possible such as with strong stitching, but may be made with temporary stitching, hook-and-loop fasteners and the like, in other embodiments. 
       FIG. 9  illustrates a fully assembled triplet  20  in a fourth configuration after six connections have been made between the squares. The connections or bar stitchings  17  are indicated. The quadrants, buds or nubs  14  are visible. In this configuration, the buds  14  are more prominent and generally conical in shape. Adjacent buds of a same square  15  are separated by finished stitching  13 . A surface texture  5  is visible on the exterior side  1  of the squares. Assembled triplets  20  are combined into a final product as further described. 
       FIG. 10  illustrates components of a stem  30  according to a first embodiment including a covering and a core. With reference to  FIG. 10 , a stem includes a core  22  that is wrapped in a covering  23  such as a fabric or other material such a green fabric with a pattern and texture reminiscent of a plant stem. For example, the covering  23  may be a green felt, green wool, green polyester, or patterned green-brown spandex. The fabric  23  includes a first edge  24  that runs substantially parallel to an axis defining the core  22 . The covering  23  includes an inner surface  25  and an outer surface  26 . The covering  23  includes a second or lateral side that is of a lateral dimension  28  sufficient to allow for at least one complete covering of the core  22 . The covering  23  is shown as a single piece, but may take the form of multiple pieces assembled or formed to the core. 
       FIG. 11  illustrates a partially assembled stem  30 . The core  22  is wrapped with a covering  23 . The core  22  is shown as a hollow core that forms a void or passage  29  through the center of the stem  30 . When assembled, the covering  23  may be stitched to itself, to the core  22 , or may be attached or assembled with a glue, rivets or other fastener or substance. Preferably, the covering  23  is of a greater length  31  than a length  32  of the core such that excess material that stretches beyond the ends of the core  22  may be wrapped over the ends. The outer surface  26  of the covering  23  is the only thing visible after the stem  30  has been formed. 
       FIG. 12  illustrates a portion of a fully assembled stem  30  according to a first embodiment. With reference to  FIG. 12 , an end of a stem  30  is wrapped in a covering  26 . A void  29  is visible in the end of the stem  30 . An end portion  26 A of the covering has been folded over and tucked into the void  29 . The end portion  26 A may be attached with any fastener or means such as glue, hot glue, staples, stitching, plastic connectors, and the like. 
       FIG. 13  illustrates a first triplet  20 A placed onto a stem  30  according to a first embodiment. With reference to  FIG. 13 , the stem  30  is placed through the first triplet  20 A in a passage formed by the connected squares  15 A,  15 B and  15 C. Each of the squares  15 A,  15 B and  15 C is connected to the other two squares by bar tackings  17  or other means. Ornamental strings  8  are visible on the ends of the quadrants  14 . The first triplet  20  may be placed anywhere along the length of the stem  30 . According to an illustrative implementation, the first triplet  20 A is placed at a proximal end  33  of the stem  30 . The first triplet  20 A is anchored to the stem  30  with one or more tacks, staples, rivets and the like. According to one specific illustrative technique, triplets are attached to a foam stem  30  with an Avery Dennison brand tacking or fastening tool (Fitchburg, Mass.). Such tool attaches two items together with one or more plastic-based fasteners. Each triplet  20  is securely fasten to the stem  30 . Other triplets are added and fastened near or adjacent to the first triplet  20 A on the stem  30  as further described next. 
       FIG. 14  illustrates a second triplet  20 B placed onto the assembly shown in  FIG. 13 . With reference to  FIG. 14 , the stem  30  is placed through the center of the second triplet  20 B in a passage formed by the connected squares  15 A,  15 B and  15 C. The squares  15 A,  15 B and  15 C are connected to each other with bar stitchings  17  generally along a portion of the seams  13  toward the outer edge of each square  15 A,  15 B and  15 C. As shown, the second triplet  20 B is placed onto the distal end  34  of the stem  30  and subsequently slid into place (see  FIGS. 15 ,  17 ). The second triplet  20 B is rotated on the stem  30  through an angle of rotation (not labeled) such that quadrants  14  of the second triplet  20 B nest into recesses between the quadrants  14  of the first triplet  20 A when the second triplet  20 B is pressed up against the first triplet  20 A. That way, the nubs or quadrants  14  of the second triplet  20 B and the nubs or quadrants  14  of the first triplet  20 A blend seamlessly together to provide an appearance of nubs  14  seamlessly emanating from the stem  30  along the length of the stem  30 . Once slid into place, the second triplet  20 B is also anchored or attached to the stem  30  so that the second triplet  20 B does not move after assembly. Following this pattern, further triplets are placed on the stem until a substantial portion of the stem  30  is covered from the proximal end  33  to the distal end  34 . 
       FIG. 15  illustrates the second triplet of  FIG. 14  placed adjacent to the first triplet and placed in its final or assembled position. With reference to  FIG. 15 , the stem  30  is placed through the center of the first triplet  20 A and second triplet  20 B in a passage formed by the connected squares  15 A,  15 B and  15 C of the two triplets  20 A,  20 B. The second triplet  20 B nests into recesses between the quadrants  14  of the first triplet  20 A when the second triplet  20 B is pressed up against the first triplet  20 A along the axis of the stem  30 . That way, the nubs or quadrants  14  of the second triplet  20 B and the nubs or quadrants  14  of the first triplet  20 A blend together to provide an appearance of nubs  14  seamlessly emanating from the stem  30  along the length of the stem  30 . Following this pattern, further triplets are placed on the stem until a substantial portion of the stem  30  is covered from the proximal end  33  to the distal end  34 . 
       FIG. 16  illustrates an artificial  Cannabis  leaf  40  for joining into an assembled set of triplets  20 . With reference to  FIG. 16 , a  Cannabis  leaf  40  includes distinctly shaped fronds  41  emanating from an end of a central stock  42 . Each of the fronds  41  includes regions of jagged edges  43  and a central vein  44  along a central axis of each frond  41 . While  FIG. 16  is shown in black and white, it is to be understood that each leaf  40  is preferably made of a green material that is reminiscent of leaves of an actual  Cannabis  plant in terms of texture, pattern and one or more colors (e.g., hues). The size of each leaf  40  is selected so as to be consistent with the size of a nub or quadrant  14  as illustrated in other figures—not excessively varying from the size of the nubs  14 . 
       FIG. 17  illustrates a completed plush item  45  assembled from components (e.g., triplets  20 , stems  30  and leaves  40 ) according to a first illustrative embodiment of an artificial  Cannabis sativa  plant. With reference to  FIG. 17 , a mostly or completely finished plush item  45  includes a set of triplets  20  assembled onto and fastened to the stem  30 . In a preferred implementation, either the proximal end  33  or the distal end  34  is covered with nubs or quadrants  14  with a triplet mounted substantially proximal to such end so as to obscure the end of the stem  30 . The triplets  20  include nubs  14 . A filament  8  is attached to an end of the nubs  14 . During assembly both triplets  20  and leaves  40  are attached to the stem  30 . Alternatively, the leaves  40  may be attached to the triplets  20 . 
     The leaves  40  may individually be placed at random places between the nubs  14  and fastened to either the nubs  14  or other portion of the squares, or the leaves  40  may be attached directly to the stem  30  or the coating of the stem. Due to size restrictions, a certain number of triplets  20  are capable of being attached to a stem  30  of a certain size. An arbitrary but not excessive number of leaves  40  are added thereto to provide a natural appearance to the plush item  45 . A proximal end  33  and distal end  34  of the stem  30  are visible at ends of the item  45 . In a preferred implementation, either the proximal end  33  or distal end  34  of the stem  30  is not visible when the item  45  is fully assembled. 
       FIG. 18  is a flowchart of steps of a method  50  for forming a plush item (e.g., Teddy Bud) according to a first embodiment of the invention. With reference to  FIG. 18 , one step  52  includes assembling pillow components from cloth. For example, squares (shown completed in  FIG. 5 ) are assembled by folding, stuffing, etc. Another step  54  includes forming squares into sets of squares (e.g., a triplet formed from assembling three pillows together, each pillow having plush buds). An example of a finished triplet is shown on a stem in  FIG. 13 . Another step  56  includes assembling a stem. Yet another step  58  includes forming a plush item (e.g., a finished pillow) by fastening sets of pillows to the stem and fastening artificial leaves to the stem or pillows. One set of pillows is nested up against and into another set of pillows. Thus, one triplet is nested up to and against another triplet so as to provide a substantially continuous set of buds along a length of the stem. 
     Conclusion. In the previous description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of the invention.
