DETAILED DESCRIPTION OF THE INVENTION

[0018] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0019] Referring now to FIGS. 1 through 7, the present invention may provide a unitary double-knit fabric adapted to provide intrinsic chambers 20 and passageways 16 for holding and passing, respectively, extrinsic objects 14, 22 therein and therethrough, and a method of making the same. The present invention may include: knitting needles 30, whose size may vary based on desired finished product; two or more lengths of filament 12, such as yarn, to be worked simultaneously with the knitting needles 30 (these filaments 12 can be the same or different colors depending on desired product, but typically are the same type and weight. Type and weight can vary based on the project, but typically match each other); a knitting pattern or schematic, not shown, that will guide creation of the final product (patterns will vary based on desired product); extrinsic object of choice 14, 22 (coin, marble, ball bearing, insulated material, etc.).

[0020] A method of making the present invention may include the following. A user may cast filament onto the knitting needles 30. The number of stitches cast on should be double the number of stitches facing one side of the finished product (Note: facing refers to the side you are looking at a given time. A user would cast on double the number of stitches so that they have the same number on both sides of the fabric). The maker would proceed to turn work. Pass the first filament 12 over second filament 12 at start of each row to create a solid selvage 10 joining the two faces of the fabric. You can change which side a particular filament is facing during the creation of the fabric by passing the first knit filament and second knit filament from one outer side to the other, effectively switching the sides they are on so that the facing filament is reversed. In this context, facing filament refers to which of the two filaments you see on the side of the cloth facing you.

[0021] Knit as pattern dictates. Referring to FIG. 2, use steps (a) passage step and (b) chamber step below as needed throughout this process. [0022] (a) To create the mouth of a passage: Refrain from passing one filament 12 over the other at the start of each row for appropriate number of rows. Do this until the mouth 18 in the selvage is the size needed to pass through desired intrinsic object 14, 22facilitating a hole 18 in the selvage 10 that allows insertion and removal the intrinsic object 14, 22 from the fabric after the article is completed; and/or [0023] (b) To create a pocket or chamber 20: When half way through the last row of a particular color block, slip the desired foreign object between the knitting needles 30, between the two halves of the fabric. Knit as directed by the pattern, closing off the mouth creating a closed pocket 20enabling insertion of the extrinsic object 14, 22 during creation and permanently kept inside the two halves of the fabric.

[0024] The premise of a double-knit fabric is to have a cloth twice as thick as a regular fabric. This is achieved by knitting essentially two cloths at once, often times in two contrasting colors. As desired, the colors can cross back and forth from one side of the fabric to the other. This is done for an aesthetic effect, to have interesting patterns in the cloth, made up of different color blocks. The design on one side is the inverse of the design on the opposite side.

[0025] At the change of one color block to another, a natural barrier occurs by virtue of the strands of filament 12 crossing from one side to the other. Thus, a pocket or chamber 20 is formed on the inside of the fabric, closed in by the barriers of filament 12 and the two sides of the fabric.

[0026] The present invention utilizes those barriers. A knitter working a double-knit project may twist the filaments 12 (or, pass one filament 12 over the other) at the start of each row so as to create a smooth, continuous selvage 10. By not twisting the filaments 12 for a number of rows, a hole or mouth is created in the selvage 10 that could allow an extrinsic object 14, 22 into the cloth. An example of this would be to leave one inch of the edge of a scarf open. From there a user may knit a pattern that looks like a maze, and then introduce a marble as the extrinsic object 14. Then the user or wearer may push the marble 14 through the maze by manually working the marble 14 through the passages 16 afforded by the fabric.

[0027] In addition, one can add in an extrinsic object 14, 22 while knitting the cloth. Then, once the colors are switched again, the extrinsic object 14, 22 will remain in place until the cloth is destroyed. An example of this would be to knit a vest with a checkerboard pattern. As the user knits the pattern, when they come to a row where they want to switch colors to create a new row of squares, the user may slip some insulating material as the extrinsic object 14, 22 in-between the needles 30.

[0028] One could apply this process to any double-knit pattern in the knitting lexicon. However, the inventor has authored patterns that specifically use this pattern. When double knitting, refrain from twisting the filament 12 at the start of a row for approximately and ( to 1 ) inch's worth of cloth, facilitating a hole 18 that can be used to pass an extrinsic object 14, 22 through the fabric. If one does the same on the far end of the cloth, one can pass the extrinsic object 14, 22 all the way through from one end to the othervia a passage way 16as long as the design permits it. In addition, when halfway through the last row of a particular color block, slip the desired extrinsic object 14, 22 between the knitting needles 30, between the two halves of the fabric. Knit as directed by the pattern, closing off the mouth 18 creating a closed pocket 20.

[0029] Knitting needles 30, filament 12, and an idea of the pattern are necessary. The nature of the foreign object to use depends on the knitter's desired outcome for the cloth. You may make chambers, passages, or both, depending on your needs.

[0030] Chambers and passages can be applied wherever you like in the pattern, and in any order, depending on color placement (i.e., you cannot have a passage if the pattern is checkerboard, as each change in color creates a barrier. You would need to leave a path for the foreign object to pass through). By using this process described herein, passages 16, and pockets/chambers 20 can be knit into a double-knit cloth without unsightly seams or extra fabric.

[0031] Additionally, the present invention is generally applicable to making cloth and clothes, but it could also be used to make tools, toys, perhaps even used in the making of fences, electrical wiring, etc., so long as a double knitted technology applies. This process can allow for these and many more applications, some of which have yet to be imagined.

[0032] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
