Zippers are used to merge two material or article halves to one another through subsets of teeth that are secured with the teeth facing away from the edge surface of the fabric. For example, a zipper may be used to merge to halves of a garment, a bag, luggage, a pocket, sporting goods, camping gear (e.g. tents and sleeping bags), and so forth.
The present description will be understood more fully from the detailed description given below and from the accompanying drawings of various embodiments of the present embodiment, which is not to be taken to limit the present embodiment to the specific embodiments but are for explanation and understanding.
The disclosed single-finger zippers will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
Throughout the following detailed description, a variety of single-finger zipper examples are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same as or similar to the specific portrayal of a related feature in any given figure or example.
A zipper is a device used to bind or connect the edges of an opening of fabric or other flexible material. For example, the zipper may be used to connect edges of a garment, a bag, a clothing article (e.g., jackets and jeans), a piece of luggage, sporting goods, camping gear (e.g. tents and sleeping bags), and so forth. Conventional zippers include a slider that locks subsets of teeth in parallel. Each tooth in the subset of teeth faces away from the edge of a halve of the material. A conventional zipper is operated by a user using one hand to hold the edges of the halve of the material together and a second hand to pull the slider one direction to connect the teeth or another direction to disconnect the teeth.
The user operates the conventional zipper using two hands due to an outward-oriented shear force of the halves of the material when the material is pulled taut. For example, the teeth of a conventional zipper extend outwardly from the edges of the halves of the material so that the teeth face toward each other and allow the edges of the material halves to be fastened together along the edges of the material halves. The conventional zipper requiring two hands to operate the zipper may make it difficult for a user to operate the zipper in a variety of circumstances and environments. In one example, when a user is hunting, climbing, engaged in sports, carrying an object, or otherwise has one of his/her hands engaged and unavailable, the user may not be able to operate the conventional zipper. In another example, when the hands of a user lack dexterity, the user may not have the ability to operate the conventional zipper with two hands.
Implementations of the disclosure address the above-mentioned deficiencies and other deficiencies by providing a method, system, device, and/or apparatus to interlock or connect to edges of a material together with a single finger or hand. The method, system, device, and/or apparatus may include a zipper with a slider configured to vertically interlock teeth of the zipper. An advantage of the single-finger zipper may be to enable a user to move the slider of a zipper with a single finger by applying pressure to a top surface of the slider and sliding the slider in a first direction to disconnect the teeth of the zipper and the halves of the material and in a second direction to connect the teeth and the halves of the material.
The chain 107 may be a continuous piece that is formed when teeth 106 connected to both halves of the single-finger zipper 102 are interconnected. The teeth 106 may be individual elements that make up the chain 107. The slider 104 may be a device that moves up and down the chain 107 to open or close the single-finger zipper 102. The tab may be integrated into the slider 104 and a user may hold and/or apply pressure to move the slider 104 in different directions, such as left and right or up and down. The tape 109 may be a fabric part of the single-finger zipper 102. The tape ends may be the fabric part of the single-finger zipper 102 that extend beyond the teeth at the top and/or bottom of the chain. The stop may be an apparatus affixed to the top end of a single-finger zipper 102 to prevent the slider from coming off the chain. The bottom stop or the bridge stop may be an apparatus device affixed to the bottom end of the single-finger zipper 102 to prevent further movement of each half of the single-finger zipper 102 from separating. The pin may be an apparatus used on a separating zipper type (such as a zipper on a coat or jacket), to allow the joining of the two single-finger zipper 102 halves. The box may be an apparatus used on the separating zipper type to correctly align the pin and begin the joining of the single-finger zipper 102 halves. The sealer may be a material fused to each halve of the zipper tape to connect the teeth to the halves of the material and reinforce the single-finger zipper 102.
The slider 104 may be configured to vertically interlock the teeth 106 of the single-finger zipper 102. In one example, a first subset of teeth 106a may be connected to a first portion of the article 100 and a second subset of teeth 106b may be connected to a second portion of the article 100. The first subset of teeth 106a may be configured to point downward and the second subset of teeth 106b may be configured to point upward, relative to each other, such that the first subset of teeth 106a and the second subset of teeth 106b are oriented at 90 degree angles relative to the edges of the halves of the article 100 such that the first subset of teeth 106a and the second subset of teeth 106b may vertically interconnect along a z-axis. The vertical interconnection of the first subset of teeth 106a and the second subset of teeth 106b may reduce or eliminate strain shear stresses and tensions of the halves of the article 100 along the x-axis and y-axis and allow a first halve of the article 100 to overlay a complementing a second halve of the article 100.
When the first subset of teeth vertically interlocks with the second subset of teeth, the teeth of the zipper may interlock such that at least a portion of the halves of the article 100 superpose on top of each other or overlap each other. In one example, the slider 104 may be configured to only contest the linear stresses and resistances native to the subset of teeth 106a and 106b and not the outward shearing forces from the conventional zipper configurations.
In one example, the teeth of the single-finger zipper 102 may include a first subset of teeth 106a and a second subset of teeth 106b. A tooth 106 of the first subset of teeth 106a and/or the second subset of teeth 106b may include a lower body 214 with a channel 216 extending along a horizontal plane partially into the lower body 214. The tooth 106 may include a cavity 218 at an end of the channel 216 location along the horizontal plane at a middle portion of the tooth 206.
In one embodiment, a tooth 106 of the first subset of teeth 106a may be connected to a top portion of the article 212a by an end of the top portion of the article 212a being inserted through the channel 216 into the cavity 218. In one example, the end of the top portion of the article 212a may be bunched up or compacted into the cavity 218 such that the tooth 106 may be secured to the end of the top portion of the article 212a. In another example, when the end of the top portion of the article 212a has been inserted into the cavity 218, the channel 216 may be clamped or compressed onto the end of the top portion of the article 212a. In another embodiment, a tooth 106 of the second subset of teeth 106b may be connected to a bottom portion of the article 212b by an end of the bottom portion of the article 212b being inserted through the channel 216 into the cavity 218. In one example, the end of the bottom portion of the article 212b may be bunched up or compacted into the cavity 218 such that the tooth 106 may be secured to the end of the bottom portion of the article 212b. In another example, when the end of the bottom portion of the article 212b has been inserted into the cavity 218, the channel 216 may be clamped or compressed onto the end of the bottom portion of the article 212b. The top portion of the article 212a and/or the bottom portion of the article 212b may correspond to the edges of a pocket, ‘the fly’ of pants, a closure, and so forth.
In another embodiment, lower body 214 may include a basal structure for the tooth 106. The basal structure may aid in securing the tooth or the single-finger zipper 102 to the article 212a or 212b. In one embodiment, the lower body 214 may be a single body formed through plastic injection molding directly to the material, such as a fabric article or a textile article. In another embodiment, the lower body 214 may include two separate jaws that may be punched together or secured together through snap fits where a fastener retains the platform to the material. The fastener may be epoxy, a hook, a snap, and so forth. In another embodiment, the lower body 214 may include a longitudinal dimension equivalent to the tooth. In another embodiment, the fastener may be a grip with the channel 216 and the cavity 218 that allows the article 212a or 212b to be passed through the channel 216 and the cavity 218 that is centered on one of the distal surfaces of the lower body 214 and formed of a rectilinear profile. For example, the channel 216 and the cavity 218 provide a top jaw and a bottom jaw of the lower body 214 where an opposing distal end of the lower body 214 may unify the top jaw and bottom jaw.
In one embodiment, the first subset of teeth 106a may be arranged in a linear, equidistant manner on a single pleat, a platform, or an edge of the material or article 212a and the second subset of teeth 106b may be secured to a corresponding second pleat, a platform, or an edge of the material or article 212b. The second subset of teeth 106b may be linearly equidistant between subsequent teeth and oriented so that the first subset of teeth 106a and the second subset of teeth 106b may engage in an alternating arrangement. In one embodiment, the first subset of teeth 106a may overlay the second subset of teeth 106b.
In one embodiment, when the material or the article 100 (as in
In one example, to interconnect the teeth 106 of the first subset of teeth 106a and the second subset of teeth 106b, the slider 104 may be slid forward such that the first subset of teeth 106a may be inserted through the top opening 222a and the second subset of the teeth 106b may be inserted through the bottom opening 222b. As the teeth 106 of the first subset of teeth 106a and the second subset of teeth 106b are inserted through the top opening 222a and the bottom opening 222b, respectively, the top opening 222a and the bottom opening 222b may be directed toward each other at a middle portion or slider cavity of the slider 104 at an angle to vertically interconnect the teeth 106, as discussed above. When the teeth 106 are interconnected together, the teeth 106 may then exit out a back opening 224 of the slider 104. To disconnect the teeth 106 from each other, the slider may be slid backward so that the first subset of teeth 106a and the second subset of teeth 106b move from the back opening 224 to the top opening 222a and the bottom opening 222b, respectively, and are disconnected by the divider 220 angling the teeth 106 at the reverse angle.
In one example, the upper body 330 may include a notch 332 (also referred to as a grip slot) extending downwardly into a top surface of the upper body 330, such as at a horizontal center of the upper body 330. In another example, the neck 326 may include a protrusion 328 extending from a first side and/or a second side of the neck 326. The notch 332 may correspond to the protrusion 328, such as both the notch 332 and the protrusion 328 be located along a center portion of the tooth 106. When a tooth 106 of a first subset of teeth 106a is interconnected with a tooth 106 of a second subset of teeth 106b, the protrusion 328 may be inserted into the notch 332. In another example, the notch 332 may be located on the top surface near the longitudinal center of the tooth 106 and horizontally coincident with the protrusion 328. The notch 332 may span the lateral distance of the individual tooth and may form a rectilinear depression therein that runs between the major dimensions of an ovular body of the tooth 106.
In one embodiment, one or more of the teeth of the first subset of teeth 106a and/or the second subset of teeth 106b may be the same size as the teeth of a conventional zipper. In another embodiment, one or more of the teeth of the first subset of teeth 106a and/or the second subset of teeth 106b may be wider than the teeth of the conventional zipper tooth to accentuate the notch 332 and protrusion 328 to arrest translational motion of the tooth 106 when the single-finger zipper 102 is in a closed position.
The notch 332 of a first tooth 106 may engage with protrusion(s) 328 of second tooth 106 to arrest any translation motion when the single-finger zipper 102 is in the closed position, preventing the closure from being pulled open. The necks 326 of the first and second teeth 106 may be in a mirrored arrangement to allow the alternating teeth 106 of the second subset of teeth 106b of teeth to engage with the first subset of teeth 106a. The protrusion 328 of a tooth 106 may extend from a top surface of a tooth 106 on an interior bottom of the neck 326 that engages with the notch when the single-finger zipper 102 is in a closed position to arrest translational movement. In one embodiment, each neck 326 of a tooth 106 may include a protrusion 328 to provide a translational retaining mechanism between clustered teeth 106 in an alternating arrangement.
In another embodiment, the single-finger zipper 102 may be configured to eliminate shearing forces exerted on the edges of the halves of the material and the interlocking subsets of teeth 106 and 106b of the single-finger zipper 102. For example, by elongating the longitudinal dimension of the subsets of teeth 106a and 106b to accommodate for the notch 332 and/or a protrusion 328, the teeth 106 may be prevented from moving translationally. Elongating the longitudinal dimension of the subsets of teeth 106a and 106b with the notch 332 and/or the protrusion 328 may securely retain the subsets of teeth 106a and 106b as they interlock together at 90-degree angles or approximately 90-degree angles relative to the edges of the halves of the article 100. The approximate 90-degree angle may range from a 45-degree angle to a 135-degree angle.
As discussed above, the slider 104 may slide along the teeth 106 of the zipper 102 to merge and/or divide the first subset of teeth 106a and the second subset of teeth 106b in
In one example, the slider 104 may include a base portion 434 located at a vertical bottom of the slider 104 and a middle portion 440 located a vertical middle of the slider 104. The slider 104 may also include a first pleat aperture 436 at a first side of the slider 104 between the middle portion 440 and a top portion 441 of the slider and a second pleat aperture 437 at a second side of the slider 104 between the base portion 434 and the middle portion 440. The first pleat aperture 436 may be a space or a slit to allow a first or portion of the article 212a (in
In one embodiment, the first pleat aperture 436 and/or the second pleat aperture 437 may follow a curvature of an obtuse-angled surface of the exterior of the slider 104 to bend and spread the first subset of teeth 106a and the second subset of teeth 106b, respectively, allowing the first subset of teeth 106a and the second subset of teeth 106b to disengage from one another when opening and interlock to one another when closing the zipper 102. In another embodiment, a curvature of the first pleat aperture 436 may be a mirrored congruency with a curvature of the second pleat aperture 437. In one example, the slider 104 may include a rear opening 438 to provide an opening for the interlocked first and second subsets of teeth 106a and 106b to exit once the first and second subsets of teeth 106a and 106b are interconnected. In another example, the rear opening 438 may provide an opening for the interlocked first and second subsets of teeth 106a and 106b to enter the slider 104 that have already been interconnected to disengage or disconnect the first and second subsets of teeth 106a and 106b.
The slider 104 may include a top portion or platform 441. An exterior surface of the top platform may include finger holder with a flat portion 442, a first angled portion 444, and a second angled portion 446. In one example, the flat portion 442 may be located at a middle section of the top portion 441 along a horizontal plane and between the first angled portion 444 and the second angled portion 446. The first angled portion 444 may extend forward and upward at a first angle relative to the horizontal plane of the flat portion 442. In one embodiment, the first angle may be between 1 degree and 89 degrees. In another embodiment, the first angle may be between 30 degrees and 60 degrees. The second angled portion 446 may extend rearward and upward at a second angle relative to the horizontal plane of the flat portion 442. In one embodiment, the second angle may be between 1 degree and 89 degrees. In another embodiment, the second angle may be between 30 degrees and 60 degrees. In another embodiment, the first angle may be the same as the second angle.
In another embodiment, the flat portion 442, the first angled portion 444, and the second angled portion 446 may form a concave structure configured to receive a finger of a user. For example, the concave structure may have a U-shape that approximately fix a convex curvature of a tip of a finger of the user. In another embodiment, the first angled portion 444 and/or the second angled portion 446 may be flanges located on the topmost, obtuse-angled surface of the slider 104. The flanges may extend outward in the horizontal direction to provide protection to the underside surface of the material. In another embodiment, the concave structure may provide a first degree of retention when pressed by the finger of the user to allow translation along the teeth 106 of the zipper 102 in
In one embodiment, the first angled portion 444 and/or the second angled portion 446 may have smooth surfaces. In another embodiment, the first angled portion 444 and/or the second angled portion 446 may have ridged surfaces or raised surfaces. In another embodiment, the top surface of the slider 104 and/or the ridges may include a friction coating that provides a defined amount of friction that retains the slider 104 to the pressed finger of the user as the user operates the slider 104 to connect and/or disconnect the teeth 106. The friction coating may increase a grippability of the slider 104 by the user. For example, the friction coating may increase the grippability of the slider 104 for the user to operate the slider 104 with a single finger.
In another embodiment, the interior of the slider 104 may include a hollow cavity that is shelled out from the exterior. The walls of the slider 104 may have a uniform in thickness throughout. The interior of the slider 104 may interlock and unlock the first subset of teeth 106a and the second subset of teeth 106b in the open space therein. For example, the hollow cavity may be an open hollow space at an interior of the slider 104 where the first subset of teeth 106a and the second subset of teeth 106b may engage or disengage when the slider 104 is moved linearly along the first subset of teeth 106a and the second subset of teeth 106b as the zipper 102 is opened or closed. The rear opening 438 of the slider 104 may be located at the rear of the slider 104 and provide an opening to the hollow cavity. The rear opening 438 may allow the interlocking first subset of teeth 106a and the second subset of teeth 106b to enter and exit the slider 104 as the zipper 102 is opened or closed, respectively.
The teeth divider 450 may guide the first subset of teeth 106a and the second subset of teeth 106b of
