Adjustable length clothing system and method of using the same

Abstract

An adjustable hem system and method for altering the length of a pants leg while preserving the hem. The system includes at least one set of fasteners mounted to the interior surface of the pants leg. A first fastener of the set of fasteners is positioned above the hem, and a second fastener of the set of fasteners is positioned closer to the hem. When engaged, the first and second fasteners create an outer fold on the exterior of the pants, allowing the finished hem to remain visible as the terminal edge. Multiple rows of fasteners may be included to enable different length adjustments. The fasteners may be pre-mounted on a flexible panel with an adhesive or provided on a strip with complementary fastener components. The method enables users to quickly adjust pant length without sewing, preserving garment appearance and functionality across various footwear styles.

ADJUSTABLE LENGTH CLOTHING SYSTEM AND METHOD OF USING THE SAMEREFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of provisional patent application Serial No. 63 / 677,036 filed July 30, 2024, titled Convertible Length Pants, the entirety of which is incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] Tailoring pants to accommodate various footwear styles has long been a practical necessity and an aesthetic challenge. One of the most common alterations involves hemming the leg openings to shorten the pants. This is typically done when the original length interferes with the desired look or function of certain shoes, such as sneakers, boots, or heels. However, while traditional hemming techniques allow for a customized fit, they come with limitations, particularly in terms of preserving the natural look and structure of denim.

[0003] When denim is hemmed using conventional stitching methods, it often loses the factory-finished appearance that gives the pants their authentic character. In some cases, tailors try to preserve the original hem by cutting and reattaching it — a process that requires careful work and still doesn’t always yield a seamless result. Furthermore, denim, being a heavy and durable fabric, does not lend itself easily to repeated alterations and does not typically use large hems to allow for lengthening. Removing old stitches to redo a hem or making multiple adjustments over time can compromise the integrity of the fabric and leave visible signs of wear.

[0004] The time and labor involved in traditional hemming methods also pose practical concerns. Visiting a tailor, waiting for alterations, and potentially needing follow-up adjustments consume both time and resources. For individuals who regularly switch between footwear with different heel heights or styles, this process is far from efficient. Further, most individuals do not have the skills or equipment to hem their own.SUMMARY OF THE INVENTION

[0005] Given these limitations, there is a clear desire for innovation — specifically, a more dynamic and user-friendly method of adjusting pant length. In at least one embodiment, a solution involves integrating at least one fastener plurality of rows of male and female snaps pre-installed on the inner surface of the lower pants legs. These coordinated snaps would allow a user to quickly engage or disengage rows depending on the desired pant length. With this system, one could seamlessly switch between a longer or shorter inseam based on the day’s footwear or weather, all without the need for tools, stitching, or trips to the tailor. In essence, this approach reimagines pant hems as adaptable components rather than fixed endpoints. It offers a blend of practicality, efficiency, and style — responding to the needs of the modem wearer who values both form and function.

[0006] While reference to male and female snaps is technically accurate, as male snaps have a protruding configuration and female snaps have a recessed or receiving configuration, the groupings of snaps referenced in the pages below may also be referred to as upper snaps and lower snaps as there is no advantage or mandate that upper snaps be male snaps or that lower snaps be female snaps. In other words, it only matters that an upper row of snaps is opposite in its configuration to the lower row of snaps.

[0007] Accordingly, in some embodiments, a system for converting pants length may involve folding excess fabric and securing the fold to the interior of the pant using snaps. The amount of fabric subtracted from the length of the pant is then folded in half with the crease of the outer fold being placed right above the stitching on the hem. The center line of the outer fold corresponds to the desired reduction in pant length when measured from where the crease of the outer fold should lay on the outside of the pants, usually located 1 / 8 inch above the hemline stitching. When the outer fold is formed, an inner fold is also created. The inner fold can be located by adding the desired length reduction to a predetermined allowance (to account for extra fabric consumed by the fold) and dividing the sum by two. To secure both folds, a row of snaps (male or female) should be placed below the crease of the outer fold but right above the crease of the inner fold. The opposite snap should be placed above the crease of the outer fold. A critical measurement characteristic is that a distance of this second row of snaps to the outer fold should equal a distance of the first row of snaps to the outer fold.

[0008] An embodiment of the present invention includes a plurality of snaps mounted to an interior of a pants leg at a location where the plurality of snaps includes a row of malesnaps (e.g., the upper snaps) and a row of female snaps (e.g., lower snaps). The upper and lower rows may each include male snaps, female snaps, or a combination thereof. A first centerline between the first row of male snaps and the first row of female snaps is positioned at a first distance from a bottom of the pants leg, where the first distance corresponds to a first length reduction of the pants leg. It is understood that the centerline is the outer fold line.

[0009] Therefore, a general object of the present invention is to provide a system and method that enables a user to quickly and easily shorten the length of their pants (Referred to in this application as being adjusted up to but not limited to 6") while still maintaining the original hem line of their pants. In some examples, the length of a pair of pants may be shortened by more than 6” (e.g., up to approximately 10” or more) as needed.

[0010] Another object of the present invention is to provide a system and method for converting (i.e., changing or altering) the length of pants (such as but not limited to denim pants) using a system of fasteners, such as snaps, and / or other suitable fastening devices for fabric (e.g., zippers, hook and loop fasteners, hook and bar fasteners, magnets, etc.). The fasteners may be aligned in multiple rows that are associated for joining together in a predetermined or coordinated manner.

[0011] Still another object of the present invention is to provide a system and method for converting a length of respective legs of pants that involves folding a plurality of upper and lower lines of snaps or alternative fastening devices for fabric in a predetermined and controlled manner.

[0012] Still another object of the present invention is to provide a system and method for converting a length of pants in which the plurality of snaps or alternative fastening devices for fabric are positioned on an interior surface of the pants to be altered.

[0013] Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In an effort to reduce production and inventory costs, some clothing manufacturers produce pants having a single length. Unfortunately, various clothing items, such as pants having a single, fixed length, do not work for all individuals due to individuals having different inseam lengths, different tastes, different footwear, etc. As a result, custom tailoring is often required to obtain a properly fitting pair of pants. Additionally, individuals may purchase multiple pairs of the same pants and have them tailored to different lengths to accommodate different types of shoes. Outside of fashion and appearance, having pants of a proper length is an important safety consideration, as pants that are too long can result in tripping and other accidents. Additionally, pants that are too long tend to drag on the ground, getting wet in bad weather and often resulting in abrasions / holes through the material of the pants. Other clothing items are also commonly tailored to adjust lengths of sleeves, legs, skirt / dress bottoms, etc. as needed to achieve a desired fit.

[0044] Described herein are convertible clothing items, such as adjustable length pants, in which an overall length of the pants can be adjusted without costly (and permanent) tailoring. In an illustrative embodiment, a series of snaps are mounted or added to fabric and then mounted) to each lower leg of the pants, on the inside of the pants. By connecting two rows of snaps and folding the pants material as described herein, the user can shorten the length ofthe pants. In another illustrative embodiment, the interior of each leg of the pants can include a plurality of sets of snaps, and the user can connect different rows of snaps to achieve different overall lengths of the pants legs. In an alternative embodiment, instead of snaps, a different mechanism can be used to convert the length of the pants, such as hook and loop tape, hook and bar, hook and eye, zipper, magnets etc. mounted to the interior legs of the pants, magnets mounted to the interior legs of the pants, covered adhesive mounted to the interior legs of the pants, etc. Additionally, similar fastening systems may additionally or alternatively be utilized to adjust various other clothing regions, such as regions having hemmed sleeves, skirts, shorts, etc.

[0045] In the embodiment of Fig. 1A, a first set of snaps includes a row of upper snaps 100 (which in this case is shown as male snaps 100) and a row of lower snaps 105 (which in this case is shown as female snaps 105) positioned adjacent to an outer fold centerline 110 and an inner fold centerline 115. The rows of upper and lower snaps may each include any suitable type and combination of snap components. For example, a row may include a plurality of male snaps, a plurality of female snaps, or a combination of male and female snaps (e.g., a row of alternating male and female snaps). The outer fold centerline 110 will be the crease of the fold that lays on the external side of the pants 120 with reference character 120 being used to designate a part of the pants, pants leg, or fabric in general). The inner fold center line 115 will be the crease of the fold that lays on the internal side of the pants 120. Specifically, the row of upper snaps is positioned above the outer fold centerline 110 and the row of lower snaps is positioned below the outer fold centerline 110 and above the inner fold center line 115.

[0046] Fig. IB shows the pinching of excess material and the resulting crease that is formed from connecting the row of upper snaps 100 to the row of lower snaps 105 with the centerline of the outer fold 110 making up the center of the crease. Fig. 1C shows the folding of the excess material 120 includes sliding the excess material upwards (i.e., into the pants leg) until the centerline of the outer fold 110 meets the point where the outer fold should lay on the outside of the pants 130. This tucking process results in a second fold, with the centerline of the inner fold 115 making up the center of the crease. The crease of the outer fold should be moved directly adjacent to the point where the crease of the outer fold should lay, or a distance above the hemline such as 1 / 16-inch, 1 / 8-inch, 1 / 4 inch, etc.

[0047] Figures 2-4 illustrate operation of the present invention and, more particularly, identifying fold lines and associated respective snap combinations for hems of different lengths.

[0048] Referring to Fig. 2, the configuration illustrates an adjustable system for shortening pants using strategically placed folds and snap fasteners. Central to this embodiment is the defined target location 200 labeled "H," typically positioned slightly above the hemline stitching 205 of the pants (commonly around 1 / 8 inch above). The precise placement of "H," indicating where the outer fold crease 210 should align after adjustment, is determined at the discretion of the garment maker.

[0049] The outer fold 210, designated as dimension "E" 215 represents the total amount of fabric length to be taken up. Dimension "E" is measured upward from location "H" 200. The inner fold 220, labeled "I" 225, is positioned between location "H" and the outer foldE-F("E") 210, and its location is calculated by the formula: 1 = —

[0050] Here, "F" refers to an allowance that accounts for extra fabric consumed during the folding process, acting as a buffer from the edge inward toward each fold.

[0051] Snaps are used to secure the folds in place, involving a lower snap ("L") 230 positioned above the inner fold 220 but below the outer fold 210, and an upper snap ("U") 235 placed above the outer fold 210. The lower snap "L" must be located at a distance greater than "I" 225 but less than "E" 215. Ideally, this lower snap is positioned as closely as possible to the inner fold 220 without intersecting or interfering with any fold lines. The distance "S" 240 denotes the length between the center of the snaps and the outer fold. Calculations for these dimensions follow the formulas:

[0052] L = E - S

[0053] U= E + S

[0054] So that the upper snap 235 and lower snap 230 are the same distance from the outer fold line 210. When these snaps are engaged and the fabric is folded accordingly, the crease of the outer fold precisely aligns with the designated location 200 "H," thereby shortening the garment in a secure and aesthetically consistent manner.

[0055] Fig. 3 expands upon the principles established in Fig. 2 to illustrate an enhanced embodiment that supports multiple incremental adjustments along the length of the pants, enabling versatile and customizable length options. Each incremental adjustment ischaracterized by three primary measurements: "E," the length of fabric to be taken up at each adjustment; "D," the distance between each subsequent adjustment; and "F," the allowance accounting for the additional fabric consumed by each fold. Each incremental adjustment is defined by the following parameters:

[0056] As with the single adjustment configuration described in Fig. 2, each incremental adjustment incorporates both outer ("E") and inner ("I") fold lines. The inner fold ("I") for each incremental adjustment is similarly calculated relative to the outer fold ("E") and allowance ("F"). Snaps are again employed, with upper snaps ("Un") and lower snaps ("Ln") maintaining the structure and precision of each fold. For each incremental adjustment, the lower snap ("Ln") must be placed above the inner fold ("In") but below the outer fold ("En"). However, due to multiple incremental adjustments, occasionally the fold lines of subsequent adjustments overlap or fall within close proximity to one another. In such cases, insufficient space exists between fold lines, making it impossible to position a snap within the intended area between "I" and "E." As a result, the snap placement shifts above the next fold line to satisfy the positional requirement: In < Ln< En

[0057] In all cases, snaps and folds remain strategically positioned to ensure efficient and aesthetically consistent fabric adjustment at multiple length intervals, despite spatial constraints. While Figs. 2-4 illustrate the complexity of possible fabric adjustments of multiple length intervals, the drawings still have limitations that should be understood, namely, while only 1 pair of snaps is illustrated for each take up, in reality the snaps may be distributed all the way around the pants leg (i.e., forming respective circles). And instead of the take ups being staggard they can all be in the same column (Fig. 3).

[0058] With continued reference to Fig. 3, a second set of snaps L2 300 and U2305 is positioned about a second centerline 310 that also serves as the outer fold. The second center line 310 is positioned E2 inches 315 upward from the designated point H 320. The upper snap 305 is above the outer fold 310 at a distance of S2 325. The lower snap 300 is above the inner fold 330 which is at a distance of I2 335 from H 320 and below the outer fold 310 at a distance of S2 325.

[0059] Similarly, a third set of snaps L3 301 and U3306 is positioned about a third centerline 311 that also sen es as the outer fold. The third center line is positioned E3 inches 316 upward from the designated point H 320. The upper snap 306 is above the outer fold 311at a distance of S3 326. The lower snap 301 is above the inner fold 331 which is at a distance of h 336 from H 320 and below the outer fold 311 at a distance of S3 326.

[0060] Similarly, a fourth set of snaps L4 302 and U4307 is positioned about a fourth centerline 312 that also serves as the outer fold. The fourth center line is positioned E4 inches317 upward from the designated point H 320. The upper snap 307 is above the outer fold 312 at a distance of S4 327. The lower snap 302 is above the inner fold 332 which is at a distance of I4 337 from H 320 and below the outer fold 312 at a distance of S4 327.

[0061] Similarly, a fifth set of snaps Ls 303 and U5 308 is positioned about a fifth centerline 313 that also sen es as the outer fold. The fifth center line is positioned Es inches318 upward from the designated point H 320. The upper snap 308 is above the outer fold 313 at a distance of S5 328. The lower snap 303 is above the inner fold 333 which is at a distance of h 338 from H 320 and below the outer fold 313 at a distance of S5 328.

[0062] Fig. 4 is an interior view of a bottom portion of a pants leg in accordance with an illustrative embodiment. This embodiment includes five sets of snaps that allow for shortening the length of the pants by 1 inch, 2 inches, 3 inches, 4 inches, or 5 inches, depending on which rows of snaps are connected to one another. In alternative embodiments, additional or fewer rows of snaps may be used. As shown, an outer fold is formed in between each adjacent row of snaps, and the adjacent rows of snaps alternate between a row of male snaps and a row of female snaps.

[0063] Still referring to Fig. 4, to shorten the pants leg by 1 inch, a row of upper snaps Ui 400, which in this case are female snaps, is connected to a row of lower snaps Li 405, which are male snaps, and tucking is performed as discussed above. To shorten the pants leg by 2 inches, the row of female snaps lower snaps L2 410 is connected to the row of male upper snaps U2 415, and tucking is performed. To shorten the pants leg by 3 inches, the row of male lower snaps L3 420 is connected to the row of upper female snaps Lb 425, and tucking is performed. To shorten the pants leg by 4 inches, the row of lower female snaps L4430 is connected to the row of upper male snaps U4 435, and tucking is performed. To shorten the pants leg by 5 inches, the row of male lower snaps Ls 440 is connected to the row of female upper snaps 445, and tucking is performed. Additionally, shortening by 2 inches, 3 inches, or 5 inches also results in alignment of other rows of snaps, which can be connected to one another to improve the stability of the shortened pants leg.

[0064] Fig. 4 illustrates an embodiment designed to address situations where incremental adjustments overlap, requiring multiple snaps from different increments to share a common space between fold lines. Due to constraints in space, upper snaps ("Un") from one incremental adjustment and lower snaps ("Ln") from another incremental adjustment may occupy the same horizontal row or alignment. To ensure compatibility, these shared snaps must be of the same type (either both male or both female).

[0065] Even with shared snaps, the essential relationships governing snap placement relative to their corresponding folds remain consistent. Specifically, the distance between each snap ("Un" or "Ln") and its associated outer fold line ("En") must still align with previously established principles. The spacing ("S") remains critical to maintaining proper functionality:

[0066] En + D = En+l

[0067] Un= En + Sn

[0068] Ln= En - Sn

[0070] This configuration accommodates multiple incremental adjustments in pants length effectively, even when faced with complex spatial limitations. In Fig. 4, Ui 400 and L2 410 share the same vertical placement. This arrangement arises because the lower snap Li 405 must be positioned above the first inner fold Ii 450 but below the first outer fold Ei 455 complying with the positional constraint In < Ln < En. For placement of the upper snap Ui 400, the distance relationship can be expressed as Un - En= En- Lnwhich simplifies to Un = 2En- Ln. This formula must also be satisfied so that lower snap Li 405 and upper snap Ui 400 are the same distance from their respective outer fold line Ei 455. For Ui - Ei to equal Ei - Li, Ui 400 is then placed below the third inner fold line L 460.

[0071] Additionally, the second inner fold I2465 is situated between the first outer fold Ei 455 and first inner fold Ii 450. Although it would be ideal to position the lower snap, L2 410 as close as possible to I2 465, the space between the first outer fold Ei 455 and the second inner fold I2465 is insufficient to accommodate a snap without intersecting fold lines. To address this, the lower snap L2 410 is instead placed above the first outer fold Ei 455 but below inner fold I3 460, positioning it as closely as possible to inner fold I2 465 without crossing fold lines. This results in the sequential positioning: I2 < E1 < L2 < I3 < E2. Due tothis arrangement, lower snap L2 410 and upper snap Ui 400, which both reside below inner fold h 460 and above outer fold Ei 455, share a single snap 470, serving both the first and second incremental adjustments.

[0072] Shared snap placement occurs again in Fig. 4 with snaps U2 415 and L5 440. Lower snap L5 440 must comply with the constraint In < Ln< Enwhere lower snap L5 440 is positioned above inner fold line Is 480 and below outer fold E5 485. Based on calculations with specific inputs (where D 490 equals 1 inch, F equals 0.125 inches and Ei 455 equals 1 inch), outer fold Es 485 equals 5 inches from the point where the outer fold should lay, H 495, and inner fold I5 480 equals 2.4375 inches or 2-2 inches when measured from point H 495. Lower snap L5 440 should thus positioned greater than 2.4375 inches but less than 5 inches from point H 495.

[0073] As the lower snap, L5440, should be as close to its respective inner fold line, I5 480, as possible, and the next fold line above inner fold Is 480 is outer fold E3 496, located 3 inches from point H. This results in snap Ls 440 being optimally positioned at 2.75 inches as its greater than inner fold I5 480 at 2.4375 inches and less than outer fold E3 496 at 3 inches. For upper snap U2 415, the placement must satisfy the relationship Un = 2En- Ln. As the center of lower snap L2410 is 1.25 inches from reference point H 495, and outer fold E2 475 is 2 inches from point H 495, U2 415 vertical placement should equal 2.75 inches. As the vertical placement of the upper snap for the two inch-take up U2415 and the lower snap for the five inch take up L5 440 both equal 2.75 inches, they can share a single snap 497. The embodiment maintains structural integrity, ease of use, and aesthetic consistency through strategic snap placements and shared attachment points.

[0074] The snaps used to facilitate length adjustments can be mounted to a snap panel. As used herein, a “snap panel” or “mounting layer” refers to a piece of fabric configured to span the interior width of the pants leg and extend vertically by a distance sufficient to accommodate one or more length take-ups. The snap panel or mounting layer serves as a base to which one or more rows of fasteners, such as snaps, are affixed. It may be formed from a flexible cloth material such as a natural fabric (e.g., cotton, silk, etc.) or a man-made fabric (e.g., polyester, etc.), and can optionally include an adhesive backing. For example, fasteners (e.g., snaps) may be affixed to and / or may protrude from a front side of the snap panel fabric and a heat-activated adhesive film may be applied to the back side of the snap panel fabric, allowing the panel to be thermally bonded to the inside of the pants leg. Alternatively, the snap panel may be attached using other methods such as an adhesive (e.g., glue), a heat-activated adhesive (e.g., iron on adhesive), a blind hem, a sashiko stitch, sewing, tape, etc. The snap panel may also be implemented using an adhesive liner such as a Flexible Adhesive liner from Bemis, a stitchless garment adhesive from Bostik, etc.

[0075] In another embodiment, snap tape, which is a commercially available product consisting of a fabric strip pre-fitted with snap components, may be used in place of a custom snap panel. Each row of snap tape can be attached to the interior of the pants leg using an adhesive, iron on application, stitching, tape etc. In yet another embodiment, the snaps may be applied directly to the pants leg, for instance by grommeting the snap components into the fabric of the pants. However, in such cases, the back side of the snaps may be visible from the exterior of the garment. In another embodiment, each set of snaps (i.e., a row of male snaps and an adjacent row of female snaps) can be mounted to a strip of flexible or semiflexible material that mounts to the interior of the pants leg, with a flexible centerline material between the corresponding snaps (see, e.g., Figs. 10A and 10B).

[0076] Figs. 5A to 5D depict the folding / tucking operation described herein. Specifically, Fig. 5 A is a side view of a pants leg with a set of primary snaps 100, 105 and a set of secondary snaps 102, 112 in accordance with an illustrative embodiment. The secondary snaps located closer to the outer fold 110 are not necessary for the shortening mechanism to work but can help to increase stability of the folds. Fig. 5B depicts the pants leg partially folded such that the male / female primary snaps and the male / female secondary snaps are aligned in accordance with an illustrative embodiment. As shown, the folded edge occurs along the centerline that is positioned in between the row of primary female snaps and the row of primary male snaps. Fig. 5C depicts the pants leg in a shortened configuration with the primary male / female snaps and the secondary male / female snaps connected to one another in accordance with an illustrative embodiment. A secondary centerline 125 is depicted along with a position of the original hem line 115. Fig. 5D depicts an alternative embodiment, in which a hook and bar system 108 is used instead of snaps to maintain the pants leg in a shortened configuration in accordance with an illustrative embodiment.

[0077] Fig. 6 depicts a liner, also referred to as an insert and as a snap panel 70, having rows and columns of snaps, which is attached to the interior of the pants leg using fabric adhesive. The snap panel may include a plurality of slits 80 each being positioned to correspond to a respective centerline or fold line so as to enhance the capability of the fabric to fold about the imaginary longitudinal axis defined by the fold line. These slits 80 act aslines of weakness or perforation, each having a longitudinal that facilitates pivoting and folding along the desired crease, thereby contributing to a smoother folded appearance.

[0078] The slits 80 are placed where the creases of the interior and exterior folds are intended to form, guiding the fabric to naturally fold at this location when upper and lower snaps are connected. In one embodiment, each slit 80 is approximately 0.25 inches in height to accommodate outer and inner fold lines that are positioned closely together. For example, in the configuration shown in Fig. 4 (in which E=1 and D=l, inner fold 2 465 and outer fold 1 455, as well as outer fold 2 475 and inner fold 4 470, are spaced approximately 2 / 32 inches apart. Due to the proximity of these fold lines, a single row of slits 80 (also referred to as cutouts) may accommodate both folds.

[0079] In the embodiment shown in Fig. 6 the cutouts are 1.25 inches wide and are positioned between the columns of snaps. The distance from the center of the snap to the nearest edge of the cutout is 0.625 inches. Columns of snaps next to the side seams may be oriented either perpendicular (90 degrees) to the hem or parallel to the side seams. When the snap columns are perpendicular to the hem, the cutouts are also onented perpendicularly. When the snap columns next to the side seams are parallel to the side seams, so that they are not at a 90-degree angle to the hem, a distance of 0.625 inches between the snap column and cutouts are still maintained. In such configurations, the slits may also be angled to align with the snap orientation.

[0080] It should be understood that a snap panel 70 may be configured with associated pairs of snaps (e.g. male and female) at predetermined distances apart so that pants to which the snap panel is adhered can be adjusted (e.g., taken up) according to any of the predetermined snap patterns. More particularly, Fig. 6 is a detailed view depicting various combinations of rows of snaps that can be connected together to result in shortening a pants leg by 1 inch 600, 2 inches 605, 3 inches 610, 4 inches 615, 5 inches 620, or 6 inches 625, depending on the user’s needs, in accordance with an illustrative embodiment. In alternative embodiments, the system can be designed using smaller / narrower snaps or other connectors that enable shortening of the pants leg in increments other than 1”, such as 1 / 2” increments, %” increments, etc. In other alternative embodiments, fewer or additional rows of snaps may be used.

[0081] In an illustrative embodiment, the proposed system for enabling convertible length pants can be incorporated into the pants legs by the manufacturer. Upon purchase, the pantscan come with detailed instructions informing the purchaser how to adjust the length of the pants. As a result, the user is able to adjust the pants length to a number of different lengths, depending on the number of sets of snaps mounted to the pants legs. The instructions according to a preferred embodiment are illustrated in Fig. 12 and described here. It is understood that the process of changing the length of one’s pants can be accomplished by the wearer themself while actually wearing the pants. First, step 20 indicates that a wearer starts with the pants hanging at their full and current length. The next step 25 is for a wearer to locate the snap panel on the inside of the pants leg and determine how much to shorten pants. The next step 30 is for a user to use the labels next to each snap to connect the snaps that correspond to how much the pants are to be shortened. Then connect any additional snaps between the main snaps and the fold. Step 35 illustrates that once the snaps are secured, a user should flip the hem down and observe that a fold on the outside of the pants should be present. If the wearer does not need to preserve the original hemline, the fold becomes the new bottom of the pants.

[0082] The method for changing the length of the pants may continue at step 40 where a user is instructed to take the folded fabric now evident on the outside of the pants leg and flip it down in the direction of the user’s shoes. If the user chooses to not preserve the original hemline, the fold becomes the new bottom of the pants. If the original hemline look is preferred, the user can continue to the next step. Step 45 reflects the method step of adjusting the hem by pulling it slightly to ensure it sits smoothly and is positioned right above the original stitching. If needed, the user can iron or physically massage the fold to help it lay flat or, as indicated at step 50, use an iron for the same purpose.

[0083] In another embodiment, the proposed system can be installed into the pants after market, by a purchaser or tailor. In such an embodiment, a single set of snaps may be used such that the user can transition between the original length of the pants, and a desired shortened length. Alternatively, multiple sets of snaps can be used as discussed above to provide multiple options for shortening the pants to different lengths.

[0084] With specific reference to Figs. 7A / 7B and Fig. 8, the method of attaching the snap panel 70 to the fabric of the pants 120 using a silicone press pad 90 will now be described in greater detail. The press pad 90 is a tool used to create a flat yet slightly cushioned pressing surface during the heat-based installation of the snap panel. In an illustrative embodiment, the press pad 90 is a sheet of silicone with holes drilled to correspond to the placement of the snaps on the snap panel 70. In Fig. 8 the press pad 90 isplaced beneath the snap panel 70 with adhesive backing 71 so that the snaps can nest into the holes, allowing the fabric surface of the panel to he flat and enabling uniform pressure when heat is applied. This ensures consistent adhesion of the snap panel 70 to the pants leg 120 without interference from the raised snap components.

[0085] Alternative materials that may also serve as effective press pads include rubber, felt, high-temperature textiles, and heat-resistant polymers, provided the material is sufficiently soft to absorb snap height yet firm enough to support consistent pressure. The material should also be capable of withstanding heat from a press or iron without degrading or transferring residue.

[0086] The press pad 90 is preferably, slightly larger than the snap panel 70 itself to avoid unwanted press lines (Fig. 7A). Further, each hole in the pad should include sufficient border 72 around each corresponding snap (Fig. 7B), which facilitates proper alignment of the snap panel while minimizing excess material near the press site. For ease of placement , the hole should be slightly larger than the snap to allow for a margin of error in case the snap is not perfectly placed on the fabric; however the border should still be close enough to avoid creating press lines.to. In a practical example, if using 7.5 mm snaps which is 0.295 inches, a hole of 0.375 provides sufficient tolerance for slight misalignment without impacting adhesion of the snap panel to the pants. As an aid to understanding a preferred assembly of a snap panel, Fig. 9 includes a series of illustrations showing the layered assembly of the components described above.

[0087] As shown in Fig. 9, the snap panel 70 may be constructed with an adhesive backing, such as a heat-activated adhesive film 71. When heat and pressure are applied, the adhesive layer 71 bonds the panel 70 to the inner surface of the pants leg 120. The press pad 90 supports this process by creating a flat surface across the snaps and fabric.

[0088] It is important to note that the press pad 90 is not an adhesive layer and does not remain affixed to the pants. It is a reusable tool employed during the heat bonding process. In alternative embodiments, other pressing aids made of comparable heat-resistant and pressureabsorbing materials may be used in place of the silicone pad.

[0089] To summarize, the snap panel 70 includes rows of male and female snaps that, once attached to the interior surface of the pants leg allow for foldable and adjustable length customization., These snaps are strategically positioned along the lower portion of the pants leg engaged to secure a fold that shortens the pants without permanent alteration. Thisapproach provides a reversible and adjustable hemming solution. In this process, a press pad 90 (typically made of silicone or an alternative suitable material) serves as a pressing aid to ensure that the adhesive layer 71 on the snap panel 70 is evenly bonded around the snap regions.

[0090] In some embodiments, one or more sets fasteners (e.g., a row of male snaps and an adjacent row of female snaps) can be mounted to a strip of flexible or semi-flexible material that mounts to the interior of the pants leg, and the two strips of flexible or semiflexible material can be connected via a thin, flexible material that is semi-transparent positioned at the above-discussed centerlines. As a result of using the flexible material at the centerline, a flat crease can be achieved when the adjacent rows of snaps surrounding (e.g., positioned above and below) the centerline are attached to one another. In one embodiment, the flexible material in between the two rows of snaps can be cloth, such as cotton, polyester, or mesh. In such an embodiment, the two rows of adjacent snaps and the flexible material over the centerline are an interconnected unit that mounts to the interior of the pants leg. This interconnected unit ensures that the male row of snaps is aligned with the female row of snaps to help prevent misaligning the snaps during installation and use. Alternatively, the centerline in between the two rows of adjacent snaps can be formed by the original material that forms the pants leg (e.g., denim) such that a mesh or other flexible material is not used in between the strips of male and female snaps. In another embodiment, instead of mounting the snaps as strips (formed on adhesive, tape, or other material), individual snaps can be secured to the interior of the pants leg to form the rows of male snaps and female snaps.

[0091] An illustrative example of this type of snap system, including a flexible centerline material and adhesive-backed strips, is discussed in connection with Figs. 10A and 10B. Fig. 10A is a rear view of a snap system that includes a set of snaps separated by a mesh material in accordance with an illustrative embodiment. Fig. 10B is a front view of the snap system of Fig. 10A in accordance with an illustrative embodiment. The rear side of the snap system includes a first strip of adhesive material 500 on a fabric 525, a second stnp of adhesive material 505 on the fabric 525, and a strip of mesh material 510 that separates the first strip of fabric 525 from the second strip of fabric 525. The first strip of adhesive material 500 is behind a row of male snaps 515 and the second strip of adhesive material 505 is behind a row of female snaps 520. In an alternative embodiment, the first and second strips of adhesive material 500 / 505 can be a heat-activated iron on adhesive. Alternatively, a non-heat-activated adhesive may be used.

[0092] As shown in Fig. 10B, the strip of mesh material 510 includes a marked centerline 530 for use in mounting the snap system to the pants leg 120, as discussed in more detail below. In the embodiment shows, the centerline 530 is printed or stitched onto the strip of mesh material 510 as a dashed line and acts as a marker for the outer fold discussed earlier. Alternatively, a solid line or other marking may be used to indicate center. In an illustrative embodiment, the centerline 530 is centered between the row of male snaps 515 and the row of female snaps 520. Depending on the embodiment, the row of male snaps 515 and female snaps 520 do not need to be centered on the strip of fabric 525. This off-center configuration makes it easier for a sewing machine to stitch on the outside edges to create a blind hem, as it has more space. With snaps centered on the fabric 525, one cannot blind hem a strip of snaps into the pair of pants because the male snap gets stuck in the feed. Additionally, in alternative embodiments, the strip of mesh material 510 may be replaced by any flexible material that is transparent or translucent such that the centerline on the material can be aligned with markings on the pants leg, as discussed below.

[0093] It is to be understood that Figs. 10A and 10B are example embodiments, and that other configurations of snaps and / or other fasteners may be used to implement the convertible length pants in alternative embodiments. For example, in one embodiment, the snaps can be attached in the form of grommeting, and injection molding can be used to secure the snaps onto a piece of fabric (or other material) that is then attached to the interior of the pants leg using glue, adhesive, stitching, etc. In such an embodiment the rows of snaps may be visible from the exterior of the pants leg.

[0094] In an embodiment shown in Fig. 11 A, alternating male snaps 705 and female snaps 710 may come on a roll 700 with an adhesive backing and may be 0.5 inches apart when measuring from the center of the snap. As shown in Fig. 11B respective strips of alternating snaps may be adhered to pants and by sewing the bottom of the strips into the hem 115 for additional security. During use, the respective strips 715 may be engaged to shorten the pants leg as described previously.

[0095] Although the embodiments described herein utilize rows of snaps to implement the pants adjustment, in alternative embodiments attachment mechanisms other than snaps may be used. In one embodiment, each lower row of snaps can be replaced by a male strip of a hook and loop fastening system or a similar material and each upper row of snaps can be replaced by a female strip of hook and loop fastening system. In another embodiment, hook and bar fasteners, hook and eye fasteners can be used to replace the rows of snaps. In anotherembodiment, zippers can be used to replace the rows of snaps. In another embodiment, each row of snaps can be replaced by rows of magnets and metal strikes such that adjacent magnets in adjacent rows are oriented to be attracted to one another. In another embodiment, strips of adhesive can replace the rows of snaps and can be connected to one another to shorten the length of the pants leg as discussed herein. To prevent the strips of adhesive from sticking to the user’s leg / socks when the system is not in use, the strips of adhesive can be covered by a peel off layer (e.g., parchment paper, waxed paper, etc.) that can be removed when the system is to be used. Once mounted, the system can be used as discussed above with reference to Figs. 1-3.

[0096] Fig. 13A through 14C illustrate an additional modification to the convertible length system that addresses excess fabric created when adjusting the length of a flared pants leg. Fig. 13A is a partial bottom view of a flared pants leg with a take-up, secured by snaps, already applied. With flared pants, the diameter of the pant opening is larger than the circumference of the upper portion of the bottom of the pants. As the upper portion of the pants leg is folded over 110 and moved down to be right above the hem of the pants leg, the hem becomes constrained, creating excess fabric gathering at the original hem line.

[0097] To help alleviate the unwanted fullness at the hem due to the difference in circumference, a hook and bar or flexible wire can be used to secure extra fabric on the interior of the pants leg. For example, consider a pair of flared jeans with a hem circumference of 21 inches. Measuring 3. 125 inches up from the hem, the circumference of the pants is reduced to 18.5 inches. If the user wanted to shorten the pants by 3 inches, they would connect the 3 inch snaps and fold the excess fabric on the exterior of the pants down to 0.125 inches above the hem line 130. This results in a mismatch in circumference as the fold, having a circumference of 18.5 inches, is now right above the hem, with a circumference of 21 inches, leaving 2.5 inches of extra fabric at the hem. In this scenario, the fabric that gathers at the hem can be secured with a hook and bar, as shown in Figure 13A - 13D, neatly tucking the excess fabric inside the pants leg, thus preserving the clean, tailored look of the jeans while achieving the desired length adjustment.

[0098] Another alternative method for concealing the excess fabric with flares is to use flexible wire. Figures 14A illustrate another embodiment in which a flexible wire may be sewn into the hem 800 and / or the side seams 802 of the pants. Adding wire to the hem and side seams allow for the fabric of the pants 120 to be molded and shaped in a manner to conceal the excess fabric as shown in Figure 14B. Once the excess fabric is tucked and foldedvertically on the inside of the pants, the hem can “flip out” instead of curling under, becoming straight and no longer gathered as illustrated in figure 14C.

[0099] In summary, as discussed herein, the majority of pants made for women come in only 1 length. This is done because manufacturers prioritize a wide variety of styles and waste sizes for women over offering a variety of lengths. As pant length can be altered at a local tailor to match a woman’s height, manufacturers expect women to take the initiative and spend additional dollars for their pants to fit correctly. By picking a singular length, women must also commit to wearing a certain type of shoe with those pants as shoe heel height can range from 0.25” to 6.” By using the proposed sy stem of internal snaps, pants can be adjusted to a variety of lengths to accommodate different heights. Snaps are connected together on the inside of the pants to create a fold, thus shortening the pants. If there is an existing hem line, this fold is then placed a distance (e.g., 0.125 inches, 0.5 to 1 centimeter) above the hem line stitching. If there is no hem line, the fold becomes the new bottom of the pants.
