CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from Canadian Patent Application No. 2,977.144, titled DETACHABLE T-SHIRT COLLAR, filed on Aug. 23, 2017, filed on behalf of the same inventor and applicant below. The entire content of Canadian Patent Application No. 2,977,144 is incorporated by reference herein in its entirety.

TECHNICAL FIELD

This invention relates to a detachable T-shirt collar for a typical common T-shirt also referenced as a collarless garment where the collar can be attached and reattached very quickly without damaging the T-shirt.

BACKGROUND

In the clothing industry, it is known to have detachable collars for shirts as far back as the 1880's. Since then there have been detachable hoodies, detachable raingear and other detachable accessories, where the attachment tabs or buttons or fasteners were integral with the shirt or the shirt already had a provision for attachment of a collar, similar to what some pastors/clergy wear. In this invention, the detachable T-shirt collar, DTSC, is for a regular T-shirt without any provision for a detachable collar. This invented collar is attached through or close to the stretchable T-shirt collar band at the neck to transform a regular T-shirt, old or new, into a more formal attire.

In the garment manufacturing industry, T-Shirts are made without collars from stretchable fabric and the process of making a T-shirt is becoming highly automated to produce massive volumes of T-shirts worldwide as a distinct type of unisex garment, separate and apart from shirts made with fabrics that do not stretch and do not have a collar and for which prior art exists for collars to suit those types of shirts.

T-shirts started out as undergarments as early as 1898 where the US Navy used them as undergarments but have now become general-use unisex clothing where they are form fitting and slipover the head to be put on or taken off as outer-wear. Current detachable collars do not address the pliable and stretchable nature of T-shirts where if the collars do not stretch, they will trap the user in the T-shirt when attempts to remove the shirt over the head occurs, as the attachment methods can be very strong and not expand sufficiently for the head to pass through easily. As well, current collars that do not stretch require a T-shirt to then have the collar attached or detached only when the T-shirt is being worn. It allows removal of or putting on the T-shirt when the collar is attached and is a safe and major increase in flexibility usage for and by all ages.

T-shirts are a separate genre of shirts where the fabric used in making T-shirts is defined as stretchable where the material expands to be enlarged limier an applied force. It is common for T-shirts to be of different colors where they are used for casual settings and the cost of collarless T-shirts are very cheap in comparison to shirts with collars.

SUMMARY OF THE INVENTION

Sport activities or informal work activities where T-shirts are worn by a variety of age groups can have the T-shirt transformed with a simple collar addition or collar change that is both economical and fashionable. This improvement of a detachable T-shirt collar, DTSC, a device, allows a wider group of persons the choice for fashion upgrade on a limited budget. It maintains the features of the collars being of various fabrics but with the noted improvement of the fastening device concealer) by the exterior face of the detachable T-shirt collar, DTSC, whereupon an additional fold in the collar itself of the DISC further makes the detachable collar integral with the T-shirt and virtually indistinguishable as an add-on to the T-shirt itself.

Known features are maintained where the collar is separately washable, detachable and fashionable and is for males and females in keeping with the unisex nature of T-shirt use. Other maintained features ae the exterior face being articulated to invent new fashion statement designs, independent of the attachment surfaces to the T-shirt neck band, with colors used for specific recognition of a group or company. The “belt loop-type” feature which comprises a vertical elongated strip attached at intervals to the exterior exposed rear face of the collar allows a color choice or a message strip to be inserted separately on the outer surface of the collar. The cloth fabric when stitched in production at the fold lines to the adjacent face of the collar, maintains the shape of the collar when it is attached. The connection uses a mechanical fastening where a pin with an expanded horizontal face that is perpendicular to the pin is used to coordinate with a connecting cover that secures the pin end with friction when it clamps onto the pin end to secure it and where it can be released by pulling apart the two pieces to separate the pair to repeatedly to allow connecting and reconnecting of the matched pair. Magnets connect similarly.

SPECIFICATION—DETAILED DESCRIPTION

The Detachable T-shirt Collar, DTSC, as illustrated in FIGS. 9, 10, 13, and 14 is comprised of fabric material that is made to a length as shown in FIGS. 3, 6 and 17, 20 to provide a gap at the front of the T-shirt dependent on the circumference of the T-shirt's neck band. Part 2 forming the Detachable T-shirt Collar, DTSC, where it is to be folded along the line indicated as part 1, 5 and 13 to have the top portion indicated as part 2 for the exterior face where it is the horizontal feature elongated panel indicated as part 2 throughout and as shown in the figures such as FIGS. 1, 2, 3, 4, 5, 6, 7, 9, 10, 13, 14, and is sized to match the T-shirt neck band.

The collar design is manifest as a 3 fold and 4 fold elongate complete fabrication where i) the collar has multiple folds to form the upper and lower portion and with the upper portion extending to form a fold to be the exterior face of the collar. The upper portion is the exterior face of the Detachable T-shirt Collar, forming a collar leaf, represented by first panel 2 in the illustrations, having its bottom edge in assembly indicated as part 12. The lower portion which starts below part 2 at the fold indicated as part 1, forms an interior face second panel 3. The collar, which may include stitching 7, is manifest as a 2 fold and 3 fold elongated continuity where the innermost portion of the fold is adjacent to the neck of the wearer and separates the connector from the wearer's neck. The innermost upturn fold 4 forms a third panel. The outer fold of the 2 fold lower portion allows the elongated fold to connect to the inner face of the T-shirt neck band which is indicated as part 8 throughout the illustrated figures. The additional fold of the 3 fold lower portion aligns around the neck band of the T-shirt collar and straddles neck band indicated as part 8 and which encircles the T-shirt from front indicated as part 9, to back indicated as part 10. The upper portion straddles the entire assembly over part 8 as a folded portion where it results in being virtually indistinguishable as a detachable attachment. The connectors indicated as part 6, pass through the outer fold 4 of the portion of the 2 fold lower portion and the T-shirt neck band.

In use, the connectors are covered from external view by the upper portion when it is folded over and straddles the T-shirt neck band and by the outermost fold of the lower 3 fold portion. In the mechanical attachment method, the 2-part fasteners are passing through the T-shirt neck band 8 to the DTSC as shown by part 6 on FIGS. 1, 2, 3, 4, 5, 6 and 7 and with the 2-part fastener not coming in contact with the wearer's skin to avoid any reaction with the wearer's skin. Both parts of the 2-part fastener assembly, when straddling the T-shirt neck band, are flat and grip each other for assembly and disassembly by mechanical force applied by the fingers for pulling them apart. The fasteners numbering between 3 and 9 are concealed as shown in FIGS. 1, 4 and 7. The outer face indicated as part 2 has a space between itself and part 8, except when part 11 is the next adjacent surface as indicated in FIG. 7 as is typical of regular shirts with a regular elongated collar. Magnets 6a connect similarly. The head of the fasteners 6 are interposed between the second panel 3 and the third panel 4 and pierces through the neckband 8 to the other panel. The fastener is a connection using a pin with an expanded face that is perpendicular to the pin and is used to coordinate with a connecting cover that secures the pin end with friction when it grips the pin end to secure it and where it can be released to allow connecting and reconnecting of the matched pair.

In drawings which illustrate embodiments of the invention, FIGS. 1, 4, 7 are sectional views that show the attachment relationship of the detachable T-shirt collar to the T-shirt collar band that goes around the neck of the individual. FIGS. 3 and 6 show the flattened strip that is folded to form the sectional views mentioned above to become a 2 fold or 3 fold DTSC type. FIGS. 2 and 5 are a 3D representation of the DTSC types. FIGS. 8 and 9 are the typical front view of a common T-shirt. FIGS. 9, 10, 11, 13, 14 and 15 shows the common T-shirt with the DTSC attached. The belt-loop type feature of the DTSC is not shown on every figure as it would be in part 2 of FIGS. 3 and 6 and the other occurrences of part 2. It is shown on FIG. 3 as part 2a.

Similarly, FIGS. 18 and 21 show sectional views using magnets indicated as part 6a and clips indicated as part 6b to pair the DTSC with the T-shirt collar similarly described as a collarless garment FIGS. 17 and 20 show the flattened strip that is folded to contain the grouped magnets and the clips that dip-on and dip-off to the T-shirt collar. The feature part of the DTSC covers the connection to the T-shirt neck band. FIGS. 16 and 19 are 3D representations of the DTSC.

The Detachable T-shirt Collar similarly described as a collarless garment and is illustrated in FIGS. 9, 10, 13 and 14 is comprised of fabric material that is cut to a length as shown in FIGS. 3 and 6 and FIGS. 17 and 21 to provide a gap at the front of the T-shirt depending on the circumference of the T-shirt's collar band. Part 4 as shown in FIGS. 1, 4 and 7, and 18 and 21, is sized to match the T-shirt collar band. The height of the collar part 3 at the back as shown in FIGS. 1, 4, and 7 varies but is usually about an 25 mm (1″) plus the height of the collar band and can have a tapered increase at the front towards the previously mentioned gap on either side to form the collar end as shown in FIGS. 9, 10, 13, and 14. The 2 piece fasteners are connected through the T-shirt collar band to the DISC as shown by part 6, 6a and 6b on FIGS. 1, 2, 3, 4, 5, 6, 7, and FIGS. 16,17, 18, 19, 20, and 21, with the 2 part pin or connector not coming in contact with the wearer's skin. Both parts of the 2-piece pin assembly are flat and grip each other for assembly and disassembly by separating them apart. When the magnet connector pair in 6a is used as shown on FIGS. 16, 17, and 18 or the clip in 6b is used, as shown on FIGS. 19, 20 and 21, they can be separated and joined together repeatedly. The fasteners joining 3 and 9 are concealed as shown in FIGS. 1, 4, 7, 18 and 21.
