Description

MAGNETIC AND MECHANICAL CLOSURE AND ADJUSTMENT DEVICES AND SYSTEMSBACKGROUND1. Field

[0001] The present disclosure relates to magnetic and mechanical adjustment devices for use with various articles, fit system, and line tensioning systems.2. State of the Art

[0002] How a wearable article opens and closes around the body, how it can be adjusted, as well as how well a device fits the body is highly important in the daily function of humans or even for animals. For example, wearable articles and devices can include, by way of example, garments, shoes, backpacks, sporting gear, wearable protective devices, sporting braces, orthosis, and / or prosthesis. Several factors can be weighed in how appropriate or satisfactory a wearable article or device fits the body, including whether the fit system is put on and taken off, fit with the appropriate amount of tension, and easily adjusted for comfort during use. These factors can be considered determinants in how appropriate or effective the fit of the article or device is on the body and they are directly related to how the article or device is secured or fastened to the body. Generally, the wearable articles or devices are secured to the body by tightening around the body. The mechanisms and associated methods of how articles or devices are secured to the body are hereby referred to as fit systems.

[0003] Fit systems and related devices and methods generally are operably attached to one or more flexible elongate members or tension lines (such as straps, cables, laces, etc.) with one or more attachment points or interfaces to the article or device. The attachment points or interfaces may decrease in distance relative to one another or relative to the fit system, which can be referred to as contraction or shortening. Such contraction can involve decreasing the effective length of the flexible elongate member(s) of the fit system and possibly increasing the amount of tension (or tensile loading) experienced by the flexible elongate member(s) of the fit system. Such contraction can occur when tightening or closing or other movement ofthe article or device with respect to the body. Alternatively, the attachment points or interfaces may increase in distance relative to one another or relative to the fit system, which can be referred to as extension or lengthening. Such extension can involve increasing the effective length of the flexible elongate member(s) of the fit system and possibly decreasing the amount of tension (or tensile loading) experienced by the flexible elongate member(s) of the fit system. Such extension can occur when loosening or other movement of the article or device with respect to the body.

[0004] The determinants of the appropriateness and effectiveness of a fit system may be associated with design elements of the fit system including: the mechanisms and associated methods for contraction and extension, the inherent mechanical advantage of a given fit system, mechanical reli ability of the overall system and toughness of individual components, maximum load and tension, distance between the attachment points or interfaces in the maximum contracted and maximum extended positions, profile height of the fit system, width and length of the fit system, rigidity of the fit system and its components, whether the contraction and extension is incremental or analog in nature, how smooth or abrupt is the contraction and extension, attachment requirements of the fit system, system weight and suspension forces provided by the fit system, flexibility or ability for the fit system to contour around the body, and pressure distribution of the fit system.

[0005] The mechanism / s and associated methods of use weigh heavily on the user experience of the fit system and is the driving factor for many of the other determinants of the fit system. For example, a mechanism may be mechanically effective but may have poor ergonomics. The mechanism may also affect the speed and direction of the contraction and extension. For example, the gear ratio mechanism within a fit system may provide high mechanical advantage, but a slow speed of contraction, which may be ideal for some applications and too slow for others. In other applications, the speeds of contraction and extension may be key for some applications. For example, certain military applications such as a fit system for a military aid pack or backpack may need to have a high speed of contraction and very high speed of extension such that the operator can quickly remove the pack if they need to quickly become mobile to avoid harm. In this application, a high mechanical advantage for contraction or extension may be less important because most userswould have a relatively high level of strength. In still other applications, the direction of pull of the contraction or extension may be important. For example, contracting in a single direction could cause misalignment of a knee joint in an orthosis as the user tightens the brace onto their body. In these cases, a balanced, dual direction fit system would be more appropriate. How easily a fit system performs contraction and extension is paramount in its ability to deliver optimal fit and user experience. Many users of orthopedic devices have compromised strength and / or dexterity so mechanisms and methods that make the fit system easy for them to contract to the desired amount and easily extend for release is a huge need and large benefit.Conversely, if a fit system is so easily engaged for contraction or extension that it is accidentally triggered, that can be a serious functional problem as well. Mechanism and methods drive other factors such as the inherent mechanical advantage of the system and the increments of tightening. Some applications may require small increments of contraction or extension whereas others may be optimized by larger and therefore faster increments of change.

[0006] In addition, some mechanisms and methods of fit systems may allow for an opening or separation between attachment points or interfaces whereas others may be better suited or even require the fit system to remain as a single unit between attachment points or interfaces. Some applications may require that a fit system opens up in order to don and doff the device while others may not. For example, a leg brace may require that users open up the device in order to place their leg into the device whereas protective pants for motorcycle riders may allow for a waist fit system to stay in one piece and loosen only while they pull it up to their waist.

[0007] The inherent mechanical advantage of a fit system is a byproduct of the mechanisms and the methods associated with the fit system. Such fit systems can provide a quantifiable mechanical advantage ratio wfiich is the amount of output force over the amount of input force. The speed or time needed to contract or extend the fit system a given distance is usually inversely correlated with mechanical advantage such that when mechanical advantage is high, speed is low and vice versa. Many applications differ in the mechanical advantage requirement, but most applications have a specific ratio or range of ratios that is optimal for function. If the mechanical advantage is too high or more than required for a given application, it mayunnecessarily sacrifice speed. Mechanical advantage within a fit system directly relates to the maximum tension and load of the system. The maximum tension and load of a fit system is described in detail below.

[0008] The mechanical reliability and toughness of the fit system relates to the materials utilized by parts therein, geometry, dimensions, and manufacturing methods. Specifically, the overall fit system may only be as strong as its weakest link. Some parts can fail and cause catastrophic failure while others may not. Failure of some fit systems could lead to the users getting trapped or stuck in their device or with their device. In other situations, the user may be highly dependent on the device. Failure of a fit system could potentially even contribute to a fatal accident. Reliability is therefore extremely important especially in certain circumstances and applications.

[0009] Maximum tension of a fit system is typically dependent on the maximum tensile loading of the flexible elongate member(s) of the fit system. In many applications, the maximum tensile loading relates directly to the maximum input force multiplied by the mechanical advantage. The input force is most often the manual force of the user but may be the force imposed by another person or an electronic or other automated system. The input force is transferred to the fit system members via the mechanisms within the fit system which may or may not include mechanical advantage. The tensile loading of the flexible elongate member(s) of the fit system can transfer load or force onto the user’s body. Generally, the load is directed into the body or, in other words, towards the center of the body’s long axis or the long axis of a limb but may also be slightly oblique to the direction directly towards the long axis. If such loading forces are directed in an angle that is too oblique to the long axis, they will likely cause the device to shift proximally or distally on the body unless counterbalanced by a geometric feature of the body or other feature. The amount of load transferred onto the body can also be related to other factors. For example, the amount of body exposure from the device seen by the fit system will affect how much of the tension force is transferred directly onto the body or into the device.

[0010] The loading directed into the body can apply pressure to the body.Generally, the pressure distribution applied to the body is dependent on the amount of loading applied by the fit system to the body divided by the surface area of the applied loading. Pressure distribution of the fit system is explained in further detailbelow. In many cases, the fit system can transfer some tension forces onto the device (for example, by the device changing shape or reducing in volume), thereby reducing load applied to the body. The amount of desired load or optimal load delivered onto the body by the fit system may differ per application, as the body changes, during activity changes, within certain movements, in certain positions, and / or over time. Although the optimal loads vary widely per application and other variables, optimal performance is generally seen within a definitive range. The humans and animals generally prefer a similar range of load and associated pressure onto the body and within specific segments of the body. Beyond the level of preference, loads and pressures that are beyond a recommended range may cause a reduction in blood flow and / or other damage, discomfort, or pain. Conversely, if loads and pressures are too low, the device may fall down on the body or be loose on the body which may lead to damage, discomfort, or pain.

[0011] The maximum effective length of the flexible elongate members of the fit system can be referred to as the travel within a fit system. Travel within a fit system may relate to the amount of space available for a flexible elongate member to collect into the fit system or the distance of linear teeth in a ratchet ladder. The available amount of travel within a fit system may limit the amount of load that a fit system can deliver onto the body in that the maximum travel may be reached before the user gets to their desired amount of load onto the body. Travel may also directly affect device sizing in that a fit system with greater travel is likely to accommodate a wider range of body sizes and vice versa. These factors might suggest that fit systems should always include a maximum or large amount of travel. However, while increased travel may be beneficial, it often has a negative or inverse correlation on other determinants of the fit system such as the size, profile, weight, and other factors discussed below.

[0012] The profile height of the fit system is extremely important to product developers and end users. Profile height refers to the distance that the fit system protrudes away from the body or, in other words, how much it sticks out. Developers and end users have a strong preference or requirement for the fit system to have a low-profile for the aesthetic look and finish quality that they demand. Moreover, the profile height also plays a role in function and safety. If a fit system has a large profileheight it will have a higher risk of catching on things or it may make it difficult or impossible to wear clothing over the fit system. Beyond these undesirable attributes, a fit system with a large profile can be a significant risk of injury due to the fact that if the user falls or bumps into something, the bulk of the fit system can be pushed into the body and can cause injury.

[0013] Similar to the profile height, the width and length of a fit system may also be important for applications of use. Width or length can limit applicability in some cases that may have a limited surface area of application. For example, shoes have a limited surface area that is acceptable for a fit system. Fit systems may be limited in their applicability to shoes if their width or length is over 45 mm or even 35 mm in some cases. However, beyond surface area limitations, larger width and length are far more acceptable for most applications fitting the body as compared to profile height.

[0014] In some cases, fit requirements can be very specific and a distance of one millimeter can be the difference between too loose and just right. In these cases, an analog fit system that can adjust in a continuous and controlled manner may be ideal. In other applications, incremental tightening provides the appropriate amount of fidelity while enabling for a wider array of fit system mechanisms. Incremental systems are often faster than analog systems that provide control at a micro level. All incremental systems are not created equal. Some incremental fit systems may offer small increments like 1.5 millimeters whereas others may offer large steps of 6 millimeters. Requirements for the distance between increments are specific per application but in general the range is between 0.5 mm and 8 mm. Regardless of whether a system is incremental or analog, the mechanism or method of use may provide a smooth transition as it is used to adjust fit or it may provide an abrupt experience. In general, the experience is understandably more favorable if it is more controlled and smoother. However, some cases require fast release or removal of a device.

[0015] Proposed adjustment solutions have not adequately solved for ease of use, durability, and / or profile thickness in connecting, closing, securing, fastening, or adjusting articles together. Various adjustment or fastening devices and associated methods have been proposed.

[0016] Many fastening and adjustment devices that have been invented utilize molded or fiber loop and hook systems. A molded fastener example is described in US Patent 7,488,527 (Velcro IP Holdings LLC) and a knit fiber example is described in U. S. Patent 3,539,436 (Velcro Industries BV INT KNITLOCK CORP). These and other molded or fiber loop and hook systems are not adequately durable for many applications. The loops, that are usually less than 1 mm tall and less than 0.25 mm thick, can be broken relatively easily and the hooks, which are also generally less than 1 mm tall and less than 0.25 mm thick, often deform, brake, and / or are obscured by dirt, hair, or other debris. As a result, these fastening systems often wear out quickly and limit the overall lifespan of products they are applied to. These and other molded or fiber loop and hook systems can require the user to push respective hook and loop pairs together with a relatively high force through the length of the fastener in order to get adequate engagement of the fastener. Disengagement can also require relatively high force in order to release the hook and loop systems. Moreover, the hook structure of these fastening devices can inadvertently fasten to and damage the fibers of clothing and other soft goods. Hook and loop prior art can also make an undesirable loud tearing noise when disengaged as the small hooks are pulled from the loop fibers. These aspects combine to provide a user experience that can be lacking in ease and can be otherwise negative.

[0017] Fastening and adjustment devices with alternative structures or methods, compared to the molded or fiber loop and hook systems described above, have been presented. Alternative fastening and adjustment devices that include magnetic attraction and mechanical features are among those described. For example, US Patent Application Publication 20190261712A1 (Fidlock GmbH), describes a fastening device that utilizes magnetic attraction and mechanical retaining features. However, in these and other similar devices, the magnet attraction and mechanical retaining features are stacked on top of one another. As a result, the overall profile thickness is a sum of the thickness of the magnets and the thickness of the mechanical retaining features. As described above, profile thickness is extremely important to many applications, especially those fitting the body. Therefore, the added profile thickness of these and other similar devices limits their efficacy. Moreover, these devices and other similar devices include a structure that is relatively rigid. More specifically, the rigidity of the magnets and mechanical retaining features isexcessively high for applications that require contouring around the body especially at the relatively small radii of the arms and legs.

[0018] Another example of a proposed adjustment device is described in US Patent 4,941,236 (Timex Group USA Inc). This closure and adjustment device includes a strap that is manufactured with magnetic materials and / or magnets that are integrated into the strap. In these and other examples of the prior art, the retaining features are integrated into part of the magnetic attraction strap body. As such, manufacturing can be more expensive, difficult, and time consuming. Moreover, the overall structure of the device may have a larger profile thickness in order to reach a substantial amount of magnetic attraction in combination with the mechanical retaining feature requirements.

[0019] In the prior art such as US Patent Application Publication 20190261712A1 (Fidlock GmbH), mechanical retaining features and magnetic attraction are additive in profile thickness along the z-axis. Prior art such as this example, have increased profile thickness compared to the closure and adjustment device described herein because the magnets and the mechanical retaining features are stacked on top of one another. In other examples such as US Patent Application Publication 20190343239 (Sama SpA), the magnets and the mechanical retaining features are not stacked on top of one another, but the magnetic poles are not configured with the broad magnet surfaces spread out along the length and width of the part such that profile thickness is minimized. In US Patent Application Publication 20190343239 (Sama SpA). the magnetic poles are arranged perpendicular to the thickness, thereby leading to increased relative profile thickness, compared to the closure and adjustment device described herein, in order to have enough surface area for the contacting magnetic poles. Profile thickness is particularly important for wearable articles to avoid unnecessary bulk, to keep from catching the device on objects close to the user’s body, and to provide an improved aesthetic, with a more sleek or less bulky design. SUMMARY

[0020] Magnetic and mechanical closure and adjustment devices are described herein that may be useful in a variety' of applications, including connection between tension lines and products. The closure and adjustment devices in accordance withthis disclosure have relative ease in engagement and disengagement compared to prior art devices. They are also more durable compared to prior art devices while maintaining a low profile thickness and low cost of manufacturing.

[0021] The closure and adjustment device for connecting articles includes a first mating part having a body with an outer surface and an inner surface, a magnet or magnetic material, a mechanical retaining feature, and a feature for attachment to an article. The closure and adjustment device also includes a complementary' mating part including a body with an outer surface and an inner surface, a polar opposite magnet or magnetic material to the magnet or magnetic material of the first mating part with corresponding orientation, location, and surfaces, a complementary mechanical retaining feature to the mechanical retaining feature of the first mating part, and a feature for attachment to an article. The closure and adjustment device include magnetic attraction created by polar opposite magnets or magnetic material in corresponding orientation, locations, and surfaces, which thereby assists engagement of complementary mechanical retaining features, and wherein, when the complementary' pair of mechanical retaining features are engaged, the relative displacement of the mating parts is blocked in one or more directions.

[0022] In accordance with the closure and adjustment devices described herein, the magnets and the complementary' pairs of mechanical retaining features of the first mating part and second mating part have different cross-sectional areas along an x-z plane. This means that the magnets and the complementary pairs of mechanical retaining features are configured so that they are not additive in profile thickness along a z-axis. Separating mechanical features and magnetic attraction into different columns and organized along rows provides a distinct and significant advantage.

[0023] Both the mating parts of the device include a dimension along a x-axis (in embodiments, this can be considered the length, but is not limited to extending along a longest dimension of the mating parts), a dimension along a y-axis (in embodiments, this can be considered the width, but is not limited to extending along a dimension shorter than the length), and a dimension along the z-axis which can be considered the thickness. Columns are aligned with the x-axis and generally are either columns of magnetic material or they are columns of mechanical retaining features. The columns generally alternate between columns of magnetic material and columns of mechanicalretaining features but embodiments with the same type of columns next to one another are possible. Typically, three to five columns are utilized with one or two columns of magnetic material. At least one column of magnetic and mechanical features are required for each of the mating parts. The differences and advantages of these different configurations are discussed further in the description below. Rows are aligned across the y-axis and generally alternate between magnetic and mechanical features with transitional segments between columns that allow the distinct columns to interact without interfering with one another while maintaining strength and a low profile. While any number of columns and row s are possible for both mating parts, typically, the first mating part only has one or two rows while the second mating part has four to twenty rows. In this typical configuration, the first mating part is usually short in length compared to its width and the second mating part is long compared to its width while both mating parts are thinnest along the z-axis w hich can be considered the thickness.

[0024] The first mating part is usually configured at the end of a strap or at the end of an article or piece of article such as at the end of a messenger bag flap, whereas the second mating part is t pically configured along the strap or on the body of an article of application. The single row or each row of the first mating part is configured to selectively engage in a secure fastened position along any of the rows in the second mating part. In this configuration, the devices can be operated to connect and adjust the relative position of an article in that the first mating part can be easily connected and secured to the second mating part at a row that is in an advanced position or at a row' that is in a retracted position. Moreover, the relative position can be adjusted easily by repositioning or ratcheting the first mating part forward to a more advanced row' or by releasing and repositioning the first mating part backward to a more retracted row.

[0025] In accordance with the closure and adjustment devices described herein, the inner and outer surfaces of the mating parts create a mounting body for the columns and rows of mechanical retaining features and the magnetic material, as w ell as the features for attachment to an article, flexible segments or features, and / or other features. The inner and outer surfaces of the mating parts additionally serve as an operable surface for controlling engagement and disengagement.

[0026] In accordance with the closure and adjustment devices described herein, the mechanical retaining geometry or the mating geometry is a compilation of mechanical retaining features, as well as, inner and / or outer surfaces of the mating parts, and / or any other features or geometry that is involved in the mechanical interaction between the first mating part and the second mating part. The primary aspect of mechanical retaining geometry in these closure and adjustment devices are the mechanical retaining features. In accordance with the closure and adjustment device described herein, the complementary pair of mechanical retaining features block relative displacement in one or more directions. Typically, relative displacement is blocked along one or more directions that are in shear or perpendicular to the forces of magnetic attraction, in this configuration the mechanical retaining features block motion in a direction that the magnetic force is weakest while the magnets are able to maximally assist in engagement of the mechanical retaining features. The mechanical retaining features can be virtually any shape and are typically shapes that nest well or appropriately mate into one another and / or exhibit retaining properties that are appropriate for a given application. For example, in some embodiments the mechanical retaining features include one or more wave-shaped mechanical retaining features with overhanging protrusion that allow for incremental ratcheting of relative positions between inverted mating parts moving away from one another in an advancement direction while blocking relative displacement in a retained direction along the x-axis. The incremental ratcheting of relative positions between the mating parts in an advancement direction while blocking relative displacement in a retained direction, is made possible by way of angled, sloped, or wedged mechanical retaining features on one side of the mechanical retaining features to allow for the mating parts to slide past one another in one direction. On the other side of the mechanical retaining features, a steep, substantially vertical, overhanging, or blocking surface is used to block or stop relative displacement until a disengagement force is presented.

[0027] Wave-shaped mechanical retaining features are features with overhanging protrusion to additionally secure, block, or resist rotational or disengagement forces in the x-z plane that may be presented between the mating parts in an engaged position. Mechanical retaining features such as teeth-shaped mechanical retaining features can serve in a similar way when they include an overhanging face or other additionallysecuring protrusion. A rotational force such as catching a strap of a brace worn on the body may be presented onto the mating geometry while in use. In such a situation of an imposed force on the closure and adjustment device, the additional securing feature of an overhanging protrusion, or other further securing feature, can serve to maintain an engaged position of the closure and adjustment device. One or more further securing features may be integrated into the mating geometry of the mating parts and may or may not include structural reinforcement to strengthen the feature / s. In this structuralmanner, the closure and adjustment devices described herein, provide an advantage over the prior art in that the mating parts can incrementally adjust or ratchet past one another and are more durable and have a stronger holding or retaining force against forces that may be presented onto the closure or adjustment devices.

[0028] In accordance with the closure and adjustment device described herein, the force of magnetic attraction may be formed between opposite poles of two magnets (north and south poles) or between a magnet on either the first mating part and the second mating part and a ferrous metal or flexible magnetic material in the other mating part. The magnetic poles are usually oriented such that the magnets or magnetic materials of the first mating part and second mating part are oriented with the N-S pole vertically aligned along the thickness or z-axis, along their thinnest dimension. The magnets and or magnetic materials selected for these devices are magnetized through their thickness which is also their thinnest dimension. In this way, the magnets can have their broad surfaces in contact with one another which allows the magnets to be maximally thin while still producing sufficient magnetic attraction forces to be meaningful in assisting with ease of engagement and adjustment while still keeping a low profile, low device weight, low material usage, and low cost. The cost of integrating magnets into the mating parts may also be reduced by including only one or two magnets in the first mating part or the second mating part while the other mating part includes a ferrous metal and / or flexible magnetic strips of rubberized magnetic material, that may be lower in cost than multiple magnets aligned in a column on the other mating part.

[0029] In accordance with the closure and adjustment device described herein, incorporation of the magnet / s and / or ferrous materials can be over-molded, press-fit, adhesive-set, with a combination thereof, or with other means. The amount of forceand the direction of force between the mating parts can be intentionally varied in different embodiments to match the needs of different applications by way of changing attributes or configurations of the magnetic attraction including the number of magnets and ferrous materials, magnet size or dimensions, magnet material, strength of the magnet field / s, distance between magnets, placement of the magnets, and / or the orientation of the magnet / s. Magnetic force is generally additive between the two mating parts.

[0030] In accordance with the closure and adjustment device described herein, the overall thickness dimension of the device in the z-axis, with the first mating part engaged in the second mating part, is the sum, or substantially close to the sum, of the thickness of the magnets and / or magnetic material in the z-axis. Stated another way, the overall device thickness in the z-axis is defined by the sum, or substantially close to the sum, of the thickness of the magnets and / or magnetic material within the mating parts in the z-axis. What is meant by, “the sum, or substantially close to the sum, of the thickness of the magnets and / or magnetic material” is that the thickness of the magnets added together is essentially the overall thickness of the device because any additional thickness, such as very thin magnet holding features, typically add less than 1.5 mm to the overall device thickness. Thus, the overall thickness is close to or substantially the sum of the thickness of the mating magnetic material.

[0031] In accordance with the closure and adjustment device described herein, a disengaging force is a force that is directed away from normal tension forces and expected oblique forces for the application wherein the force is directed onto the closure and adjustment device by way of the attached article, and / or directly onto the mating parts. A disengaging moment is a rotational force presented between the first mating part and the second mating part that is directed away from the direction of normal tension forces and upward, away from the mechanical retaining feature / s. The direction or directions of force that enable disengagement can be considered to be a degree of freedom. Disengagement can only occur if forces presented between the parts are stronger than the force of magnetic attraction, securing forces from the mechanical retaining geometry, and / or other retaining forces.

[0032] In accordance with the closure and adjustment device described herein, a disengaging force and / or a disengaging moment are required to unfasten or disengagefrom the fastened position. The mating geometry of some embodiments require that a first disengaging force then a disengaging moment are needed to unfasten, while others can be configured to first require a disengaging moment, then a disengaging force. Other embodiments may be disengaged directly with a disengaging moment or force. In some embodiments, a disengaging force by itself will not unfasten the closure and adjustment device because a projection from the mechanical retaining features may block the mating parts from disengagement. In other embodiments, a disengaging force in the appropriate direction can directly disengage the mating parts. In some embodiments, magnetic attraction alone is used to oppose disengagement in the degree of freedom. In this way, magnetic attraction is used to maintain the fastened position while minimally inhibiting the degree of freedom for ease of disengagement. In other embodiments, mechanical and magnetic features can be used to resist disengagement. The closure and adjustment device can be configured to match appropriate disengagement forces and direction requirements to match the needs of different applications.

[0033] Some applications require relatively more security of the fastened position while other applications may value ease of engagement / disengagement not requiring a highly secure fastened position. For example, in an application where the closure and adjustment device are used for a helmet, the closure and adjustment device are configured to first require a disengagement force and then require a disengagement moment so that the helmet does not unintentionally open from forces presented on it during normal use. In an alternative embodiment, the closure and adjustment device for an application on a waist belt is configured to only require a disengagement force because unintentional disengagement forces are not common during normal use so ease of use can be maximized. The relative security of the fastened position and ease of engagement and disengagement is impacted by a number of structural features within the closure and adjustment device described herein, broadly including, the mating geometry and the magnetic attraction between the mating parts. The mating geometry varies widely in shape, size, orientation, the number of mating features, and tolerance between parts. In general, greater security comes at the cost of less ease. These and other features described herein are customizable in that they can be altered to match the needs of the specific application, in this case, to allow for more or less security of the fastened position or greater ease in use per the needs of the specificapplication.

[0034] In accordance with the closure and adjustment device described herein, the device includes one or more features for ease of disengagement. The features for ease of disengagement could be one or more pull tabs or a slot to receive a pull tab which allow the user to pull up on a piece of fabric or webbing in order to disengage the first mating part from the second mating part. Outside walls of the first mating part that are configured to provide a surface that facilitates ease of disengagement may also be provided.

[0035] Ease of engagement, adjustment, and disengagement is particularly useful for wearable articles. For example, in a knee brace or ankle brace the user of the brace typically needs to open and close or engage and disengage multiple straps integrated into the device every time they put the brace on and take it off. Oftentimes, people wearing braces need to adjust the fit throughout the day as well. For people wearing orthopedic articles such as a brace, ease of use can be especially significant and could make the difference between being able to benefit from a medical device or not.

[0036] In accordance with the closure and adjustment device described herein, the device includes a flexible capacity or structural compliance that allows it to conform around a radius that is perpendicular to the profile thickness, such as conforming around an arm or leg of the body. This flexible capacity or structural compliance is enabled in a variety of ways within the devices described herein. In some embodiments, thin and flexible living hinges or joints are provided between rigid rows. In other embodiments, the material used offers enough flexibility within the properties of the material that the only feature that is required for flexibility between rows is a flat and relatively thin geometry. Because the magnets and mating geometry are organized along rows, a segment between the rows along the x-axis allows for compliance or flexibility in the x-z plane. In other embodiments wherein the material used is less compliant, such as a stainless steel sheet metal, recess cuts or other means to increase compliance in the intended areas of conformability between rows may be included to achieve the desired amount of part flexibility. Alternatively, the invention as described could accommodate the curvature need for an application by being premolded or structural compliance could be accomplished by way of including one or more accordion or expandable and contractible sections or segments. Another meansof accommodating curvature, such as conforming around an arm or leg of the body, is that the first mating part may only include only one or two rows that thus do not occupy a large radius of the curvature. This in combination with a structurally compliant second mating part and a compliant article such as a flexible webbing strap will allow the system to effectively accommodate curvature even though the first mating part is not flexible.

[0037] Flexible capacity or structural compliance provides a distinct advantage over the prior art. In some of these embodiments, the structure of this type may be coupled with stitching flange features for attachment to an article. In this configuration, the structure is supported throughout the device, thereby eliminating risk of failure at a thin and flexible living hinge or joint sections. Most prior art that does have flexible capacity or structural compliance is constructed from small loop and hook fibers or features that lack durability and require a large contact surface area. Prior art alternatives to hook and loop fastener devices have not solved for providing flexible capacity’ or structural compliance, durability, and a low profile structure as the closure and adjustment devices described herein do simultaneously solve for those challenges. For applications around the body or other applications with relatively small radii, this flexible capacity or structural compliance enables the disclosed closure and adjustment devices to be more form-fitting, comfortable, and effective compared to rigid or non-compliant devices.

[0038] In accordance with the closure and adjustment device described herein, the first mating part and / or second mating part includes a feature or features for attachment to an article. For example, some embodiments include a stitching flange that is configured to provide a sewable surface for attachment to a webbing strap or other application surface. A sewable surface allows for someone skilled in sewing to stitch the part onto a textile application. Various types of sewing attachments such as bar tacking, zig-zag stitching, straight stitching, flat knitting, seam welding, sonic welding, and other attachment mechanisms may be used. Alternatively, a flange can be used as a moldable surface that is co-molded or overmolded and thereby is directly bonded to an application during the molding process and forms an aesthetic transition between the application and the closure and adjustment device. An alternative metal flange or tab features are used to clamp a sheet metal version onto anapplication. Other features for attachment to an article may include a through hole that is configured to provide an attachment point for a bolt, rivet, or other fastener attachment, adhesive, and / or a pass-through slot or adjustment mechanism operable for an adjustable attachment between the device and an application article.

[0039] In accordance with the closure and adjustment device described herein features for attachment to an article for the first mating part and / or second mating part includes a pair of slots that are configured to enable a webbing strap to pass through, secure within, and allow for adjustability in relative position along the strap, while securely holding position when tension is applied through the strap. This configuration allows for the user to position the second mating part on a strap at the desired location by flexing the second mating part while tension is relieved from the strap and then pushing the strap through both slots, one at a time, then straightening the second mating part at the desired location. When tension is transferred through the strap, the strap naturally crosses the slots at a steep angle as it attempts to take the shortest path between slots. The steep angle and tension in the strap thereby locks the second mating part in position so that it does not shift on the strap when forces are applied by the first mating part or other. The ability for this configuration to easily adjust the location of secure position along a strap without sewing or other means provides versatility and ease with this system that is superior to the prior art.

[0040] Movement between the mating parts that does not disengage the parts but does result in relative motion between the mating parts can be considered to be play or fastened position movement between parts. In some cases, movement between the mating parts can be useful. For example, in applications where a pivoting or partially pivoting strap attachment can assist in accommodating changes in strap angles that can happen during use. In other cases, movement between the mating parts can create a perception of instability or allow for unwanted movement. The amount of movement between parts in the fastened position of the closure and adjustment device and subsequently the amount of movement between the attached articles can also be custom altered in different embodiments by making changes to the mating geometry or clearances between parts to allow for more or less play between mating parts.

[0041] To provide additional benefit, closure and adjustment devices described herein, may also include a visual or tactile feedback system to indicate the relativedisplacement between mating parts. A visual indicator is a feature that the user can see such as a notch or groove in the first mating part that corresponds with notches, grooves, numbers, or other indicators along the x-axis of the second mating part which the user can utilize to better understand the relative position between the first mating part and the second mating part. Tactile feedback systems may be part of the same system or separate wherein notches, grooves, numbers, or other indicators can be felt by the user to better understand the relative position between the first mating part and the second mating part.

[0042] In addition to operating as a closure and adjustment device, it is hereby stated and demonstrated that this device also operates to control and retain the loose end of the strap. In accordance with the closure and adjustment device described herein, the loose end of the strap is controlled and retained with the connection and adjustable system. In this way. a loose and dangly end of the strap is avoided.

[0043] In accordance with the closure and adjustment device described herein, the mating parts can be made in a variety of manufacturing methods and with many different appropriate materials. In some embodiments, injection molded medium-hard to hard plastics between durometer scale Shore A 60 to 90 are used. In other embodiments, medium-soft to medium-hard plastics, between durometer scale Shore A 40 to 70, are used to cast the mating parts along with or without a reinforcing nonferrous sheet metal that is overmolded or strong co-molded non-ferrous plastic reinforcement. In other embodiments, non-ferrous sheet metal or other non-plastic materials are used to form the body and features within the mating parts. In other embodiments, the entire, or most of, the first mating part and second mating part are made from cut and stamped or press-shaped sheet metal. In this embodiment, the magnetic material of the second mating part may be ferrous sheet metal that is integrated with non-ferrous sheet metal along columns and the only magnet in the device is integrated into the single sheet metal row of the first mating part. In other embodiments, the first mating part and second mating part are machined and assembled and / or cut and stamped or press-shaped metal and / or plastic linkage parts assembled into a watch band with the closure and adjustment device described herein integrated into the watchband. It is important for any reinforcement materials or body materials to be made with non-ferrous materials so that it does not interfere with themagnetic fields of the mating magnets or magnetic material. In other embodiments, soft goods, woven yarn, woven materials, fabric, fibers, and / or other textiles are manufactured or used within the device.

[0044] In accordance with the closure and adjustment device described herein, the closure and adjustment device is made available in different lengths, widths, thicknesses, flexibility, strength, and / or other features or attributes to accommodate variable needs for different applications. For example, different webbing strap widths are used for different applications or within the same application. Some applications may require greater flexibility while others can benefit from a more rigid structure. Strength, security, and other requirements vary widely between applications and it is stated and demonstrated herein that the closure and adjustment devices can be designed and constructed in a way that can tailor to the appropriate configuration of the given application.BRIEF DESCRIPTION OF THE DRAWINGS

The article may' include elastic or inelastic materials or a combination of the two and may be applicable for virtually any use.

[0118] Each closure and adjustment device described herein can be part of a fit system or a line tensioning system as described herein. As used herein, a 'Tit system” refers to a closure and adjustment device connected to a wearable article with at least one tension line (flexible elongate members such as straps, cables, wires, etc.) with one or more attachment points or interfaces to the article or device.

[0119] As used herein, a “line tensioning system” refers to a closure and adjustment device connected to a non-wearable article or structure with at least onetension line (flexible elongate members such as straps, cables, wires, etc.) with one or more attachment points or interfaces to the article, device, or structure. Similar to fit systems, the attachment points or interfaces may decrease in distance relative to one another or relative to the line tensioning system, which can be referred to as contraction, retraction, or shortening, or may increase in distance relative to one another or relative to the line tensioning system, which can be referred to as extension, advancement, or lengthening. The closure and adjustment devices used in line tensioning systems may operate in space without being directly mounted to an article or structure.

[0120] As used herein, “connection” between articles by the closure and adjustment device can refer to connection and disconnection between two aspects of the same tension line, between two tension lines, between a tension line and a product, between two different products, between two aspects of the same product, or other possible connection and disconnection scenarios. The closure and adjustment devices used may operate in space without being directly mounted to an article or structure. The features for attachment to an article may also include an attachment mechanism for how the device is attached to the article. The attachment mechanism and / or article may also include a system of maintaining tension within the article during use.

[0121] Figs. 1 to 4B show details of a magnetic and mechanical closure and adjustment device 100 that incorporates magnetic features 15 and 25 as well as mechanical retaining features 17 and 27 that are organized separately along columns 101 and 103, respectively, and rows 102 wherein flexible segments 115 are included between rows 102 to provide a conformable and low-profile means of connection and adjustment. As shown in Figs. 1 to 2D and 4A-4B, magnetic and mechanical closure and adjustment device 100 includes a first mating part 1 including a body 11 with an outer surface 12 and an inner surface 13, magnets 15 with a north pole 16 and a south pole 14 stacked vertically along a z-axis, mechanical retaining features 17, and a feature for attachment to an article in the form of a stitching flange surface 18. As shown in Figs. 1 to 3, complementary mating part 2 includes a body 21 with an outer surface 22 and an inner surface 23, multiple corresponding magnetic or ferrous sheet metal pieces 25, and complementary' mechanical retaining features 27 to themechanical retaining features 17 of first mating part 1, and a feature for attachment to an article in the form of a stitching flange surface 28.

[0122] As shown in Figs. 1-4B, device 100 includes one central column 103 of mechanical retaining features 17 and 27 and two columns 101 of magnetic features 15 and 25 that are positioned adjacent to central column 103 on both sides along the y-axis. As shown in greater detail in Fig. 3 and in cross-section through the x-z plane in Figs. 2B-2D, columns 103 of magnetic features 15 and 25 and column 101 of mechanical retaining features 17 and 27, are separately organized so their profile thicknesses are not aligned vertically or in thickness along the z-axis. As described herein, this configuration provides a distinct advantage over the prior art in that it enables a lower profile device while still providing the benefits of both magnetic attraction and mechanical stability. As seen in Fig. 3, second mating part 2 includes seven rows 102 while Figs. 2B-2D and Figs. 4A-4B shows that first mating part 1 includes one row 102. Fig. 2D shows a cross-section along the x-y plane, through the single row 102 of first mating part 1 and one of the rows 102 of second mating part 2, wherein magnets 15 are engaged with magnetic sheet metal pieces 25 while complementary mechanical retaining features 17 and 27 are engaged in a fastened position that is assisted by the forces of magnetic attraction.

[0123] As shown in Figs. 1-4B, device 100 with mating parts 110 include flexible segments 115 between and at the end of rows 102 which provide flexible or compliant sections between rows and across columns. Flexible segments 115 between rows 102 may be accomplished in different ways, in this embodiment it is accomplished by way of a thinned region of body 11 and body 21 all the way across the x-axis of mating parts 110. These thin sections can be considered a living hinge in that they allow for a hinge type movement in the parts. Flexibility before and after rows 102 provides the ability for closure device 100 to contour around a radius or object that is curved such as a body of a human or animal. Living hinges can sometimes be a failure point, how ever, mating parts 110 are both reinforced with stitches 9 which support and anchor each row 102 and each column 101 and 103.

[0124] As shown in Figs. 1, 2B, and 4A, the sloped back side 32 of the w ave-shaped complementary' mechanical retaining features 17 and 27 facilitates incremental ratcheting of relative positions between mating parts 110 in an advancement direction35 while blocking relative displacement in a retained direction 36 by way of the sloped back side 32 being angled to allow for the mating parts to slide or ratchet past one another in an advancement direction 35 before snapping down into fastened position 6 along one of rows 102, as encouraged by magnetic attraction forces 49. In fastened position 6, matching wave lip protrusions 31 block or stop relative displacement in the retained direction 36, the negative direction along the x-axis in this embodiment, until a disengagement force is presented. In this configuration, magnetic and mechanical closure and adjustment device 100 is adjustable wherein the first mating part 1 single row 102 is enabled to couple with the second mating part 2 in any one of the seven rows 102 that it includes along the x-axis. In addition to blocking relative displacement in the negative direction along the x-axis, mechanical retaining features 17 and 27 additionally block or resist rotational forces and / or lateral forces that may be presented between mating parts 110. As shown in greater detail in Fig. 2D, side walls 29 of mechanical retaining features 27 interfere with lip protrusion 31 of mechanical retaining feature 17 to block rotational forces in the x-z plane, as well as, lateral forces and rotational forces in x-y plane and y-z plane, thereby blocking rotational and lateral movement between mating parts 110. As such, side walls 29 of mechanical retaining features 27 and lip protrusions 31 of mechanical retaining features 17 and 27 provide further securing features of fastened position 6 between first mating part 1 and second mating part 2. Because lip protrusions 31 of mechanical retaining features 17 and 27 are configured to be thin in profile height, in order to support an overall thin profile thickness, reinforcing structure 43 is utilized to provide a strong and durable device in spite of being thin and low-profile. The reinforcing structure 43 of device 100 is made from a non-ferrous sheet metal that is then overmolded with plastic. An additional design feature of device 100 that relates to molding of lip protrusions 31 is that a cavity or hole is incorporated into second mating part 2 under lip protrusions 31 which allows for greater ease in injection molding the part.

[0125] As shown in Figs. 1-4B, device 100 with mating parts 110 include magnets 15 and corresponding magnetic sheet metal pieces 25 to produce magnetic attraction forces 49. Both pairs of magnets 15 and corresponding magnetic or ferrous sheet metal pieces 25 create up to 2.3 lbs. of normal magnetic attraction forces 49 between mating parts 110 for a total of up to 4.6 lbs. This force is considerably highfor only 4 mm of profile thickness for mating parts 110. The ability to provide a relatively high force of attraction while maintaining a thin profile thickness is made possible by utilizing magnets that are relatively wide (along the y-axis) and / or long (along the x-axis) and thin along the z-axis wherein the north pole 16 and south pole 14 are stacked vertically on top of one another through the thickness of magnets 15, as shown in Fig 2C and 4B. In this way, the magnetic force is maximally assistive for engagement of mating parts 110 while disengagement forces only need to oppose the shear magnetic attraction forces 39 which are considerably smaller than normal magnetic attraction forces 49 aligned with polar opposites. A large amount of magnetic assistance facilitates a high level of ease in engagement of mating parts 110 and also helps to avoid accidental disengaging. An additional advantage of device 100 is that the cost of integrating magnets into mating parts 110 is reduced by including only one row 102 in first mating part 1, as well as, the use of corresponding magnetic sheet metal pieces 25 that are made with a lower cost material (a ferrous sheet metal) than many magnets. Magnets or magnetic materials can be selected based on cost, ability to bond or integrate into mating parts 110, and / or a reduced environmental impact. Magnets or magnetic materials can be bonded, overmolded, sonic welded, or otherwise affixed to mating parts 110.

[0126] As described herein, a substantial disengaging force or forces are required to disengage mating parts from the fastened position. As shown in Fig. 2B, wherein magnetic and mechanical closure and adjustment device 100 is in a fastened position 6, a first substantial disengaging force 7 is required in the positive direction along the x-axis, then a second substantial disengaging force 8, directed upward, is required to disengage mating parts 110 from fastened position 6. Two disengaging forces in specific directions are required because lip protrusions 31 and side walls 29 within the mating geometry of mating parts 110 are configured to block motion in other directions when the parts are in a fastened position 6. Alternatively, a substantial disengaging force 7 at the end of the advancement direction 35 or a substantial disengaging force 7 to push first mating part 1 to the end of advancement direction 35 may also disengage mating parts 110. The first substantial disengaging force 7 and second substantial disengaging force 8 are described to be '’substantial'’ because the disengagement forces must be sufficient to overcome tension forces 38, shear magnetic attraction forces 39, and any aspect of the mechanical retaining features thatresists forces in the direction that is opposite of the normal forces or tension forces 38 within the application. In device 100, the only aspect of the mechanical retaining features that resists forces in the direction that is opposite of the normal forces or tension forces 38 is frictional forces in pushing the sloped back side 32 of mechanical retaining features 17 and 27 past one another. Normal tension forces 38 in device 100 would be tension forces within the adjustment strap 3 and / or base strap 4 and are generally directed along a predictable path as shown in Fig. 2B. When forces presented between mating parts 110 are blocked, forces are transferred to the article through the features for attachment to an article 18 and 28. When forces presented on the article are transferred to mating parts 110, forces are transferred from the article to the mating geometry and fastened position 6 is maintained unless a first substantial disengaging force 7 and a second substantial disengaging force 8 is presented.

[0127] Fig. 1 shows stitches 9 that are used to attach first mating part 1 and second mating part 2 to adjustment strap 3 and base strap 4 by stitching through feature for attachment to an article in the form of a stitching flange surface 18 and feature for attachment to an article in the form of a stitching flange surface 28, respectively. Alternatively, mating parts 110 could be stitched to any other type of article as described herein. The stitching flange is typically between 5 and 12 mm wide in order to provide adequate surface area to run a sewing machine support foot on top, and typically surrounds the perimeter around the entire part. In magnetic and mechanical closure and adjustment device 100, features for attachment to stitching flange surfaces 18 and 28 are coupled with a supporting fabric top cover 5 and supporting flange fabric 55, respectively, to provide a sewable surface, further structural support, and / or visually appealing attachment to an article. Fabric top cover 5 and supporting flange fabric 55, by their nature, cover stitching flange surfaces 18 and 28 so it is difficult to clearly point out the stitching flange surfaces 18 and 28 in some of the figures. Stitches 9 run along stitching flange surfaces 18 and 28 so the path of stitches 9 more clearly shows where stitching flange surfaces 18 and 28 are located

[0128] In Figs. 1 to 2D, it is shown that the article of application for magnetic and mechanical closure and adjustment device 100 is adjustment strap 3 and base strap 4 which may form a belt or strap to be the article in itself or may be integrated into anarticle like a bag or orthopedic brace. Adjustment strap 3 and base strap 4 may be part of the same strap length wherein the strap returns on itself and returns upon itself to the adjustment end, or it may be two different straps. If adjustment strap 3 and base strap 4 are part of the same strap, the strap would usually pass through a loop in the article, a chafe, buckle, attached loop, or similar before returning upon itself.

[0129] As shown in the Figs. 1, 2A, and 2D, device 100 includes feedback features 62, wherein, a visual reference is included and can be referenced to confirm engagement, disengagement, and / or to indicate the relative position of the first mating part with respect to the complementary mating part, by way of feedback features 62 protruding laterally past the rest of first mating part 1 body 11. Feedback features 62 also serves as a tactile feedback feature, wherein a user can feel the lateral protrusions of feedback features 62 and complementary mating part 2 in order to reference the relative position of first mating part 1 with respect to the complementary mating part 2.

[0130] Additionally, closure device 100 includes an auditory feedback system or clicking feature, wherein, an audible noise is generated during engagement, disengagement, and / or advancement of first mating part 1 with respect to the complementary mating part 2 by way of first mating part 1 body 11 texture producing an auditory' click against corresponding magnetic sheet metal pieces 25 when arriving to fastened position 6.

[0131] Matting parts 110 of magnetic and mechanical closure and adjustment device 100 are made with injection molded plastics that are medium-hard to hard materials between durometer scale Shore A 60 to 90. As discussed above, the reinforcing structure 43 of mechanical retaining features 17 and 27 is made from cut and shaped non-ferrous sheet metal that is then overmolded within the injection molded plastic.

[0132] As shown in Figs. 2C and 2D, dimensions are provided to demonstrate the scale or size of features described herein. Scale or size may be useful to understand certain aspects of the design, however, it is hereby stated that these dimensions my vary' per the different needs of different applications. By way of example only, in an embodiment mechanical retaining features 17 and 27 are 3 mm and 3.5 mm tall inprofile height along the z-axis, respectfully; mechanical retaining features 17 and 27 are 3 mm and 3.5 mm tall in profile height along the z-axis. respectfully; and mechanical retaining features 17 and 27 are 8 mm long along the x-axis.

[0133] Further to the example, the centrally located mechanical retaining feature 17 column 103 is 6.5 mm wide and row 102 including two magnets 15 and mechanical retaining feature 17, is 26.5 mm wide, as seen in Fig 2D. First mating part body 11 is 42 mm wide, wherein the width outside of the row is a feature for attachment to an article in the form of a stitching flange surface 18 and supporting fabric top cover 5. The first mating part 1 is wide enough to cover the end and sides 38.5 mm or 1.5” wide standard strap wherein the strap end is contained, organized, aesthetically finished, and protected with mating part 1, supporting fabric top cover 5, and stitches 9. The profile thickness of first mating part 1 is 2 mm at the cross-section through magnet 15 shown in Fig. 2C, wherein 1.6 mm of the profile thickness is the thickness of magnet 15 and 0.4 mm is allocated for a thin wall of plastic to help retain the two magnets 15. As shown in Fig 2C, the length of each row along the x-axis is approximately 9 mm and flexible segments 115 between rows 102 are 2 mm long. The profile thickness of complementary mating part 2 is also 2 mm at the crosssection through magnet 15 shown in Fig. 2C, wherein the entire 2 mm thickness is a magnetic sheet metal piece 25 which is bonded and integrated into complementary mating part 2. Therefore, the overall profile thickness of magnetic and mechanical closure and adjustment device 100 is 4 mm, wherein the vast majority (3.6 mm out of 4 mm) is the profile thickness of magnets 15 and magnetic sheet metal pieces 25 used for magnetic attraction with only a minimal thickness for retaining the magnets or magnetic material. Both the first mating part 1 and the complementary mating part 2 have a larger, 3.5 mm profile thickness, with the complementary mechanical retaining features 17 and 27. However, the profile thicknesses of complementary mechanical retaining features 17 and 27 overlap one another in the x-z plane and they are separately aligned from magnetic features 15 and 25 so they do not stack vertically and do not add to the profile thickness of the overall device, as seen in Figs. 2C and 2D. Overlapping mechanical retaining features of the first mating part and second mating part along the x-z plane helps to provide strong and reliable closure and adjustment without adding unnecessary profile thickness.

[0134] The centrally located mechanical retaining feature 27 of second mating part 2 is 10 mm wide. The full row with two corresponding magnetic sheet metal pieces 25 and mechanical retaining feature 27, is 26.5 mm wide, as seen in Fig 2D. Complementary mating part 2 is 36 mm wide, wherein the width outside of the row is a feature for attachment to an article in the form of a stitching flange surface 28. Complementary mating part 2 is an ideal width for a standard 1.5’738.5 mm wide strap. As described herein for first mating part 1 and shown in Fig 2C, the length of each row along the x-axis is approximately 9 mm and flexible segments 115 between rows 102 are 2 mm long.

[0135] Figs. 5-8D show an alternative magnetic and mechanical closure and adjustment device 200 to the magnetic and mechanical closure and adjustment device 100. Specifically, device 200 differs from adjustment device 100 as follows. As shown in Figs. 5-6, magnetic and mechanical closure and adjustment device 200 is configured for and applied to a belt, more specifically, a waist belt 1000. As shown in greater detail in Figs. 7-8D, magnetic and mechanical closure and adjustment device 200 includes one centrally located column 101 of magnetic features with magnet 215 creating magnetic attraction with corresponding magnetic or ferrous sheet metal strip 225, and two columns 103 of mechanical retaining features 217 and complementary mechanical retaining features 227 that are positioned adjacent to central column 103 on both sides along the y-axis. Unlike device 100, device 200 is made primarily from cut and formed sheet metal. Sheet metal mating parts 210 include unique features such as recess cuts between rows 102 to facilitate conformability of second mating part 202, and features for attachment to an article in the form of through-hole features 280 and attachment plates 250 to allow for secure and durable connection to a leather belt material with rivets and / or stitches. Attachment plates 250 provide increased surface area for rivet and / or stitching attachment such that the attachment rivets and / or stitches are less likely to pull through the leather over time. Attachment plate 250 at the outside surface of waist belt 1000 also provides a surface that can be used to display a logo, branding, the user’s name, an image, or other graphic via laser etching or other means. As shown in Fig. 8C, corresponding magnetic or ferrous sheet metal strip 225 is flush with and retained in unison with second mating part 202 via angled perimeter cut 226 that is difficult to see in Fig. 8C due to the cross-section pattern but is further described herein to be an intentional angled cut on secondmating part 202 and a matching angled cut on corresponding magnetic or ferrous sheet metal strip 225 wherein the inside surface is larger and therefore is retained by second mating part 202 being secured onto the leather. Adhesive, press-fitting, notches, and / or other means may also be used to join corresponding magnetic or ferrous sheet metal strip 225 with second mating part 202. As shown in greater detail in Figs. 8B and 8C, magnet 215 is chemically retained within first mating part 201 by way of epoxy 251 and / or other bonding agent. Furthermore, As shown in Fig. 8B, magnet 215 includes scores or recess cuts 252 along the side walls of magnet 215. Scores or recess cuts 252 in the side walls of magnet 215 creates a mechanical retaining feature once epoxy 251 is used to bond the magnet in place which serves to further secure magnet 215 in place.

[0136] As shown in Figs. 5-6 and as described herein, the present invention includes a waist belt 1000 that includes a magnetic and mechanical closure and adjustment device 200 or similar as shown and described herein. Magnetic and mechanical closure and adjustment device 200 is designed to serve well as a closure and adjustment device for a waist belt in that it is low-profile, made with strong and durable materials, is secured to the leather belt in a strong and durable way with integrated features, allows the user to incrementally ratchet the waist belt tighter or easily loosen fit of the waist belt, and is configured such that it can conform around the shape of the user’s w aist while also providing sufficient rigidity to aid in passing the waist belt through belt loops of pants.

[0137] Figs. 9-14B show- an alternative magnetic and mechanical closure and adjustment device 300 to the magnetic and mechanical closure and adjustment device 100 and 200. Specifically, device 300 differs from adjustment device 100 and 200 as follows. As shown in greater detail in Figs. 11A-14B, magnetic and mechanical closure and adjustment device 300 is applied to a strap and forms fit system strap device 2000 including one centrally located column 103 of mechanical retaining features 317 and complementary mechanical retaining features 327, then tw o columns 101 of magnetic features with magnet 315 creating magnetic attraction with corresponding flexible magnetic strip 325 are positioned adjacent to central column 103 on both sides along the y-axis, then two narrower columns 103 of mechanical retaining features 317 and complementary mechanical retaining features 327 arepositioned adjacent to columns 103 on both sides along the y-axis. Therefore, magnetic and mechanical closure and adjustment device 300 includes two columns 101 of magnetic mating features 315 and 325 along with three columns 103 of mechanical retaining features 317 and 317, wherein the outside columns are significantly narrower than the three middle columns thereby demonstrating that not all columns need to be the same width. As shown in Figs. 12A-14B, flexible magnetic strip 325 is mounted under second mating part 302 wherein a flexible bonding material such as urethane is utilized in order to maintain flexibility across the length of second mating part 302. As shown in Figs. 12, 13C, and 14A, mechanical closure and adjustment device 300 utilizes side walls of columns 101 to further secure device 300 against rotational and oblique forces wherein body 311 and magnets 315 of first mating part 301 interferes with and is retained by the side walls of columns 101. As shown in Figs. 12A-14B, mechanical closure and adjustment device 300 also includes one row7102 of first mating part 301 and fifteen rows 102 of second mating part 302. As shown in detail in Figs. 13B and 14B, of mechanical retaining features 317 and 327 have a teeth shaped structure wherein the retaining side of the teeth are overhanging such that mechanical retaining features 317 and 327 are able to block oblique and rotational forces w hile maintaining a low profile and offering smaller increments, of approximately 6 mm. for each increment of tightening or loosening along each row. Flexible segments 115 are formed in device 300 simply by the sections between mechanical retaining features 327 wherein only body 321 and corresponding flexible magnetic strip 325 exist, thereby facilitating compliance along the x-z plane as shown in Figs. 9, 10, and 1 IB. As shown in detail in Figs. 1 IB, 13B.13C, and 14B, mechanical closure and adjustment device 300 includes novel features for attachment to an article. As shown in Figs. 1 IB, 13B, 13C, and 14B, first mating part 301 can be configured with an integrated clamping feature 382 as a feature for attachment to an article wherein a strap or article can be clamped or held. Clamping feature 382 may be made of molded plastic or may be made from sheet metal that is cut, formed, and can be overmolded or otherwise integrated into one or both of the mating parts. As seen in Figs. 11B, 13B, 13C, and 14B, clamping feature 382 can be clamped to a strap to form a strong yet low' profile union with adjustable strap 303. Alternatively, first mating part 301 can also be configured with an integrated adjustable strap 303 that is overmolded directly into first mating part 301. As shownin Figs. 9, 11, 12, 13A. and 14A. first mating part 301 is intentionally wider along the y-axis than second mating part 302, such that, the user can easily identify and pinch first mating part 301 along the sides of body 321 in order to connect, adjust, and / or disconnect first mating part 301 with second mating part 302. As shown in Figs. 9-14B, second mating part 302 includes a strap slot 383 at each end of second mating part 302. Strap slot 383 are utilized as an adjustable feature for attachment to an article wherein base strap 304 is passed over outer surface 322 at the ends and across inner surface 323 between strap slots 383. As shown in Figs. 12-13C, in this configuration base strap 304 can be fed through the two strap slots 383, one at a time to adjust the relative position of second mating part 302 on base strap 304. As shown in Figs. 14A and 14B, once a desired location is established and tension is applied through base strap 304, second mating part 302 is secured in place by way of tension in base strap 304 causing a kinked path that binds or blocks second mating part 302 from shifting along base strap 304 until tension is released. As such strap slots 383 serve as a macro adjustment wherein second mating part 302 can be shifted along base strap 304 to a desired location, then selectable connection between first mating part 301 and second mating part 302 serves as a micro adjustment for the user.

[0138] As demonstrated in Figs. 9,10, and 1 IB, this embodiment demonstrates a means of accommodating curvature, such as conforming around an arm or leg of the body, by the first mating part may only including only one or two rows that thus do not occupy a large radius of the curvature, in combination with, a structurally compliant second mating part and a compliant article of a flexible webbing strap. As shown in Figs. 9,10, and 1 IB, the embodiment effectively accommodates the curvature presented even though the first mating part is not flexible.

[0139] As shown in Figs. 9, 10, and 1 IB of fit system strap device 2000 includes buckle 392, padding 393, and elastic section 398. Buckle 392 offers separate means of connection and disconnection so that adjustment strap 303 and first mating part 301 can be pulled back upon itself for greater leverage and mechanical advantage in adjusting the fit of strap device 2000. Buckle 392 is designed for maximal ease of use and is described separately. Padding 393 is included to provide shock absorption to protect a sensitive area. Elastic section 398 is used to maintain tension within the system to provide a snug and secure fit without causing excess peak pressuresespecially during impact or temporary expansion.

[0140] As shown in Figs. 9-14B and as described herein, the present invention includes a fit system strap device 2000 that includes a magnetic and mechanical closure and adjustment device 300 or similar as shown and described herein and may include buckle 392, padding 393, and / or elastic section 398. The present invention includes a closure and / or adjustment device that includes slots at both ends that allow a strap or article to be adjusted along its length without tension applied then secure the device in place once tension is applied.

[0141] Figs. 15-17C show an alternative magnetic and mechanical closure and adjustment device 400 to the magnetic and mechanical closure and adjustment device 100, 200, and 300. Specifically, device 400 differs from adjustment device 100, 200, and 300 as follows. As shown in greater detail in Figs.l5-17C, magnetic and mechanical closure and adjustment device 400 is applied to messenger bag 3000 that includes angled mechanical retaining features 417 and 427 wherein the angled teeth of mechanical retaining features 417 and 427 converge forward and towards the center such that advancement direction 35 is suggested with an arrow type shape that operates as visual indicator feedback feature 462. Wherein the angled teeth of mechanical retaining features 417 and 427 are configured to assist in aligning the mating parts during engagement to find the fastened position by funneling the first mating part into the fastened position, further assisted by magnetic attraction. As shown in Figs. 16, 17B, 17C, first mating part 401 includes two rows 102. Two rows 102 divides the retaining forces up into two separate teeth, thereby strengthening first mating part 401. However, the spacing between rows 102 of second mating part 402 needs to be consistent in this configuration so that mechanical retaining features 417 and 427 remain aligned.

[0142] As shown in Fig. 15, messenger bag 3000 includes shoulder strap 490. Shoulder strap 490 includes a magnetic and mechanical adjustment device 400’. Magnetic and mechanical adjustment device 400' is optimized for use as a messenger bag shoulder strap in that it is configured for first mating part 401 ’ to selectively ratchet forward in advancement direction 35 or disengage and be slid up and back along the second mating part. As shown in detail in Figs. 18-19C, first mating part 401’ includes wrapping side walls 485’ at both ends along the y-axis that wrap aroundbody 421’ of second mating part 402’. Wrapping side walls 485’ of first mating part 401’ include clearance space between body 411’ and further retaining return segment 494’ along the z-axis such that, if a substantial disengagement force is presented, first mating part 401 ’ is able to shift upwards, away from magnetic attraction and engagement of the mechanical retaining features where it may be ratcheted forward or shifted back while wrapping side walls 485’ block first mating part 401’ from disengaging from being coupled with body 421’ of second mating part 402’. As shown in Figs. 18-19C, end caps 496’ are bonded onto both ends of second mating part 402’. End caps 496’ add 1.25 mm to the profile thickness at both sides of both ends of second mating part 402’ thereby adding 2.5 mm to the total profile thickness of 5 mm at each end of the second mating part 402’, along the x-axis. First mating part 401’ can’t detach or decouple from second mating part 402’ because each end of the second mating part 402’, along the x-axis, is 5 mm which is higher than the profile clearance of 3.75 mm between inner surface 413’ and outside surface 478’ of further retaining return segment 494’ of first mating part 401 ’. As such, magnetic and mechanical adjustment device 400’ is configured for adjustment but not connection / disconnection, as is required for the shoulder strap of a messenger bag. Because end caps 496’ are bonded to second mating part 402', they can be added after first mating part 401’ is assembled onto second mating part 402’. Other means to selectively allow the first mating part to slide along the x-axis of the second mating part while blocking it from decoupling from the second mating part are possible and are hereby included. Torsional and lateral stability provided by wrapping side walls 485’ make it so that funneling mechanical retaining features are not required for magnetic and mechanical adjustment device 400’.

[0143] As shown in Figs. 18-19C, other ways that magnetic and mechanical adjustment device 400’ differs from the devices previously described is that first mating part 401 ’ includes slot 457’ that is configured to serve as a feature for attachment to an article 418’ for adjustment strap 403’. Figs. 18-19C also show base straps 404’ wherein these straps both return back upon themselves as opposed passing all the way through second mating part 402’, along the x-axis. In this configuration, features for attachment to an article 428’ do not allow for second mating part 402’ to be adjusted along a base strap, however, both sides can include adjustable mechanisms of the respective sides.

[0144] As shown in Figs. 18-19C, second mating part 402’ that is made from a flat sheet material or molded plastic, composite, or other material with a flush outer surface 422’. Along with featuring a flat perimeter, the material used for the body of second mating part 402’ is flexible enough to allow?for adequate flexibility and stability for the given application. As shown in detail in Fig. 19B, complementary' mechanical retaining features 427’ are cut or molded to include a sloped back side 432’ in advancement direction 35 and an undercut or overhanging surface or protrusion 431’ in the retained direction 36. As such, mechanical retaining features 417’ of the first mating part 401' with corresponding sloped back side 432’ and overhanging surface or protrusion 431’ is enabled to ratchet past second mating part 402’ in advancement direction 35 while being adequately secured in the retained direction 36. This configuration is low-cost to manufacture and has the advantage of maintaining a flush outer surface 422’ of second mating part 402’ w hich is an advantage for an application such as this messenger shoulder strap 490 such that it avoids raised features that could catch on objects or cause discomfort to the user.

[0145] Shoulder strap 490 includes a 50 mm or 2” wide strap in order to spread out, and therefore lower, carrying forces from the strap on to the user. As such, magnetic and mechanical adjustment device 400’ is configured to accommodate a 50 mm or 2” wide strap. All previous embodiments have demonstrated magnetic and mechanical closure and adjustment devices that are configured to work with a 38 mm / 1.5’' strap or belt. Therefore, magnetic and mechanical adjustment device 400 and magnetic and mechanical adjustment device 400’ provide an example of different sizes across the same application and more variation in sizes and types can be expected across different articles.

[0146] Another aspect that makes magnetic and mechanical adjustment device 400’ ideal for the shoulder strap of a messenger bag is the strength, durability, low-profile, and low-cost construction of first mating part 401 ’ which is made out of 1.25 mm, non-ferrous stainless steel sheet metal. For the purpose of demonstrating the functional attributes of Magnetic and mechanical adjustment device 400’ more so than the aesthetic finish, a cosmetic and protective cover for the first mating part has not been shown but is included herein for appropriate applications. Magnetic and mechanical adjustment device 400’ also includes padding 493, as shown in Fig. 19Cthat provides shock absorption and added comfort for the user when carrying loads with messenger bag 3000.

[0147] As shown in Figs. 15-19C and as described herein, the present invention includes messenger bag 3000 that includes a magnetic and mechanical closure and adjustment device 400 or similar as shown and described herein and may include shoulder strap 490 that incorporates magnetic and mechanical adjustment device 400’ as shown and described herein. The present invention includes an adjustment device as described and demonstrated herein that includes a first mating part and second mating part that include columns of magnetic features and, separately, columns of mechanical retaining features, wherein the first mating part, with one or two rows, is perinatally or substantially coupled with the second mating part and enabled to selectively slide along second mating part, with multiple rows, for adjustment of the relative position between the mating parts, wherein magnetic attraction assists the mating parts to find a fastened position at a selected row and to secure in the selected row' wherein the mechanical retaining features block relative movement in at least one direction.

[0148] Figs. 20-22C show an alternative magnetic and mechanical closure and adjustment device 500 to the magnetic and mechanical closure and adjustment device 100, 200, 300, and 400. Specifically, device 500 differs from adjustment device 100, 200, 300, and 400 as follows. As shown in greater detail in Figs. 20-22C, magnetic and mechanical closure and adjustment device 500 is applied to watch band 4000 that includes mechanical retaining features 517 and 527 that are rectangular shaped. As such, mechanical retaining features 517 and 527 do not enable shifting or ratcheting relatively. This example is provided for applications where incremental adjustment options are desired but ratcheting between rows is not wanted. An alternative wristwatch band that allows for ratcheting adjustment of the strap may be desirable for some applications, and is hereby included, however, shapes of mechanical, retaining features that result in incremental adjustment options has not previously been demonstrated, and is hereby demonstrated. Mechanical retaining features 517 and 527 include clearances to allow for them to easily flex around common radii of wrists. Mechanical closure and adjustment device 500 also includes brakes 566 wherein the entire second mating part 502 is split and repeated upon itself to allow' forconformability between segments and the option of adding more or less segment increments, depending on the size of the wristwatch band or other article.

[0149] Each segment of second mating part 502 is made from injection molded plastics. Without accommodation features such as brakes 566 and clearances between mechanical retaining features, as well as, consistent spacing between, mechanical retaining features 517 and 527 would not be able to conform around a radius and may not function at all.

[0150] As shown in Figs. 21-22C, the first mating part and second mating part 502 of mechanical closure and adjustment device 500 have the same number of mechanical retaining features 517 and 527. As shown in detail in Fig. 22C, complementary mechanical retaining features 517 and 527 include straight wall interferences that block relative motion between first mating part 501 and second mating part 502 in both directions along the x-axis until a substantial disengagement force is directed upwards in the x-z plane in order to separate first mating part 501 from second mating part 502 vertically.

[0151] Mechanical retaining features 517 and 527 that are rectangular shaped are demonstrated and described herein. Alternative embodiments of the fit systems herein may include mechanical retaining features such as the wave-shaped, tooth-shaped, or rectangular-shaped mechanical retaining features that have been shown above or they could be virtually any shape, including but not limited to. circular, triangular, polygon-shaped, button-shaped, or other.

[0152] Magnetic and mechanical closure and adjustment device 500 of Fig. 20 includes only one row 102 of first mating part 501, whereas magnetic and mechanical closure and adjustment device 500 of Figs. 21-22C includes a first mating part 501 with multiple row s 102. This provides an example of how a fit system may be used by the manufacturer or end user in variable ways and many combinations of features and attributes discussed here, and can be combined in different ways to accommodate different designs and preferences.

[0153] Including multiple rows on both parts or rather only on the second mating part may offer additional adjustment options. However, a first mating part with multiple rows 102 may result in rows 102 hanging loosely past one another whereboth sides are in an advanced position. This can lead to a disadvantage of the first mating part or second mating part catching on objects moving near magnetic and mechanical closure and adjustment device 500. Also, multiple rows 102 on both the first mating part and second mating part can cause malalignment of mechanical retaining features as they try to bend around an object. This is caused by the inner surface of the first mating part constricting while the mechanical retaining features of the second mating part are spread apart as they wrap around an object.

[0154] As shown in detail in Fig. 22C, the first mating part of mechanical closure and adjustment device 500 includes subtractive mechanical retaining features while the second mating part includes additive protuberances of mechanical retaining features that spread out when bent around an object such as a leg or an arm. In this configuration the protuberances are spread open w hen bent around a curve as opposed to getting pinched or more compressed if the protuberances were on the first mating part. As shown in detail in Fig. 22. the subtractive shape integrated into the first mating part can be longer along the x-axis in order to accommodate a wider range of radii. The increased length of the subtractive shapes for any first mating part or second mating part can also be utilized as an independent variable to increase the amount of curve that can be accommodated, or used to allow for play or movement between mating parts, or used in combination with a bias or spring towards the advanced direction in the fit system.

[0155] By combining bias such as magnetic attraction created by magnets 515 and 525, with an increased amount of relative displacement allotted between mating parts in the fastened position creates an incorporated shock absorption system 574. An alternative shock absorption system could include bias in the advanced direction in the fit system.

[0156] The example provided by magnetic and mechanical closure and adjustment device 500 demonstrates and describes disadvantages of the mechanical retaining features configuration in this embodiment. Meanwhile, this example demonstrates, by w ay of contrast, a distinct advantage of a first mating part with only one or two rows. That said, mechanical closure and adjustment device 500 is still useful, and possibly ideal, for applications with a predictable range of radii, and in straight or near straight articles.

[0157] Fig. 23 shows a perspective view of a wristwatch wrist band that is an alternative to the wristwatch wrist band of Fig. 20 and includes a magnetic and mechanical closure and adjustment device 600. As shown in Fig. 23, magnetic and mechanical closure and adjustment device 600 is applied to watch band 5000 that includes mechanical retaining features 517 and 527 that are built into a metal linkage system. Other than the construction of the first and second mating parts being integrated into a watch band linkage system. In this embodiment, the mechanical retaining features and magnetic features are integrated into existing watchband systems. In these existing watchband systems, metal joints rotating in the x-z plane around the y-axis allows magnetic and mechanical closure and adjustment device 600 to conform around a wnst circumference. As seen in Fig. 23, magnetic and mechanical closure and adjustment device 600 includes flexible segments 115 that are not aligned across columns 101 and 103. Columns 101 and 103, as well as, rows 102 are organized in this embodiment with staggered flexible segments 115. All previous embodiments have demonstrated flexible segments 115 that run straight across all columns 101 and 103. Magnetic and mechanical closure and adjustment device 600 demonstrates that linkage systems or other flexible segments 115 can be staggered or aligned along rows 102. All other aspects of magnetic and mechanical closure and adjustment device 600 have already been demonstrated herein. The fit systems herein also may include other metal linkage or chain systems.

[0158] As shown in Figs. 20-23, and as described herein, the present invention includes watch band 4000 and watch band 5000 that both include a magnetic and mechanical closure and adjustment device that is shown and described herein. These w atch band devices are hereby included in the present invention.

[0159] Fig. 24 shows a sandal that includes a mechanical and magnetic fit device 120 that improves speed, ease, and durability of prior sandals.

[0160] Fig. 25 shows a child’s shoe that includes a mechanical and magnetic fit device 120 that makes it easier for children to donn and doff their shoes.

[0161] Fig. 26 shows an adult shoe that includes mechanical and magnetic fit devices 120 that make it easier for elderly population to have greater ease taking off their shoes. Fig. 26 includes additional features for ease of use 56 in the form of loopsat the first mating part.
