Title: Watchbands with hook and loop fasteners

Abstract:
A watchband can comfortably secure an electronic device to a wrist of a user. The watchband can include a base having a contact surface opposite an engagement surface, contact loops on the contact surface for contacting a user, and engagement loops on the engagement surface for engaging hooks. The hooks can be provided on the engagement surface, opposite some of the contact loops. The base can include base threads, and the contact loops and engagement loops can be formed by contact threads and engagement threads woven about some of the base threads between the contact surface and the engagement surface. Between adjacent engagement loops, the engagement thread can be more securely attached to the base than is the contact thread between adjacent contact loops.

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. application Ser. No. 15/663,654, filed on Jul. 28, 2017, entitled “WATCHBANDS WITH HOOK AND LOOP FASTENERS,” the disclosure of which is hereby incorporated herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The present description relates generally to securement of wearable devices, and, more particularly, to watchbands with hook and loop fasteners. 
     BACKGROUND 
     Some electronic devices may be removably attached to a user. For example, a wristwatch or fitness/health tracking device can be attached to a user&#39;s wrist by joining free ends of a watchband together. In many cases, watchbands may have limited fit adjustment increments available. For example, some bands have an incrementally user-adjustable size (e.g., a buckling clasp, pin and eyelet, etc.) whereas other bands have a substantially fixed size, adjustable only with specialized tools and/or expertise (e.g., folding clasp, deployment clasp, snap-fit clasp, etc.). Other bands may be elasticated expansion-type bands that stretch to fit around a user&#39;s wrist. The degree of comfort and securement of the electronic device can depend on the function and arrangement of the watchband.

     DETAILED DESCRIPTION 
     The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. 
     An electronic device, such as a wristwatch or fitness/health tracking device, can be attached to a user&#39;s wrist by a watchband. It can be desirable to maintain a secure attachment to the wrist so that the electronic device does not shift excessively or slip off of the user. Securement of the electronic device against the user can also be important to the function of electronic components, such as biometric sensors. Additionally, it can be desirable to maximize the comfort of the user while wearing the electronic device. Often, a secure attachment can apply an undesirable amount of force on the wrist of the user. In many cases, conventional watchbands may catch, pinch, or pull a user&#39;s hair or skin during use if the band is overly tight. In other cases, watchbands may slide along a user&#39;s wrist, turn about a user&#39;s wrist, or may be otherwise uncomfortable or bothersome to a user if the band is overly loose. These problems can be exacerbated during periods of heightened activity, such as while running or playing sports. 
     Furthermore, adjusting the size or fit of conventional watchbands often requires multiple steps, specialized tools, and/or technical expertise. Sizing options available to a user may be insufficient to obtain a proper fit. The fit may be different and/or may be perceived to be different given certain environmental (e.g. temperature, humidity) or biological conditions (e.g., sweat, inflammation). As a result, users of conventional wristwatches and/or fitness/health tracking devices may select a tolerable (although not optimally comfortable) fit, reserving tight bands for fitness/health tracking devices and loose bands for conventional wristwatches. However, some wearable electronic devices may be multi-purpose devices, providing both fitness/health tracking and timekeeping functionality. Accordingly, a user may prefer the fit of a watch to vary with use. For example, a user may prefer a looser fit in a timekeeping mode and a tighter fit in a fitness/health tracking mode. Accordingly, there may be a present need for systems and methods for dynamic adjustment of the fit of wearable electronic devices. 
     Embodiments of the present disclosure provide hook and loop attachment mechanisms. The attachment mechanisms provide secure attachment to a user and also provide enhanced comfort. For example, loops can be woven in a pattern to provide engagement with hooks as well as comfortable contact with the user. The loops can be woven in a manner that forms the loops on a contact side of the watchband for contacting the skin of the user and providing moisture wicking or air ventilation. Embodiments of the present disclosure provide ease of adjustment by a user as well as secure attachment to avoid inadvertent release under external forces. 
     According to some embodiments, for example as shown in  FIG. 1 , a watch  10  includes an electronic device  12  that is worn on a wrist  2  with a watchband  20 . The electronic device  12  can be portable and also attached to other body parts of the user or to other devices, structures, or objects. The watchband  20  can be flexible and encircle at least a portion of the wrist  2  of a user. By securing the electronic device  12  to the person of the user, the watchband  20  provides security and convenience. In some embodiments, the electronic device  12  includes a display  14  and a housing  16  for containing components. According to some embodiments, for example as shown in  FIG. 2 , the watchband  20  extends to an opposite side of the wrist  2  of user from electronic device  12 . The watchband  20  includes an inner portion  22  and an outer portion  24  that overlap and engage each other. 
     According to some embodiments, for example as shown in  FIG. 3 , the watchband  20  is adjustable to fit securely and comfortably onto the wrist  2  by selecting an extent of overlap between the inner portion  22  and the outer portion  24 . For example, the diameter of the watchband  20  is adjustable to be appropriate for a secure and comfortable fit on the wrist  2 . The watchband  20  removably attaches to a portion of the housing  16  of the electronic device  12  with a housing connector  30 . The watchband  20  removably attaches to another portion of the housing  16  of the electronic device  12  with a retaining ring  40 . Accordingly, the watchband is removeable from the electronic device  12  and replaced, thereby permitting a user to switch watchbands as necessary or desired. A portion of the watchband  20  passes through a hole of the retaining ring  40 , such that the length of the inner portion  22  and the length of the outer portion  24  are defined on either side of the retaining ring  40 . 
     A contact surface  26  of the watchband  20  is positionable to contact the wrist  2  of the user. Along the inner portion  22 , the contact surface  26  faces inwardly toward the wrist  2 . Along the outer portion  24 , the contact surface  26  continues as an outwardly facing surface. An engagement surface  28  of the watchband  20  is positionable to contact itself. Along the inner portion  22 , the engagement surface  28  faces outwardly away from the wrist  2 . Along the outer portion  24 , the engagement surface  28  faces inwardly toward the inner portion  22  and opposite the portion of the engagement surface  28  that extends along the inner portion  22 . A hook zone  54  is provided on the engagement surface  28  and along the outer portion  24 . The hook zone  54  is arranged to engage loops of a loop zone  52  on the engagement surface  28  and along the inner portion  22 , as described further herein. The engagement surface  28  can be arranged to avoid contact with the wrist  2  of the user. 
     According to some embodiments, for example as shown in  FIG. 4 , the housing connector  30  and a stopper  50  are located at or near ends of the watchband  20 . The retaining ring  40  is slidably connected to a base  32  of the watchband  20  and provides a connection to the housing  16  of the electronic device  12 . The contact surface  26  extends between the housing connector  30  and the stopper  50 . For example, the contact surface  26  extends to the housing connector  30  and/or the stopper  50 . The contact surface  26  provides loops extending from the base  32  for contacting the wrist  2  along the inner portion  22  and for providing an outwardly facing surface along the outer portion  24 . 
     As shown in  FIG. 4 , the retaining ring  40  can have an engagement end  44  and a hole  42  through which the watchband  20  can extend. The stopper  50  has at least one cross-sectional dimension that is larger than at least one cross-sectional dimension of the hole  42 . For example, the stopper  50  can have a lateral cross-sectional dimension, transverse to a longitudinal axis of the watchband  20 , that is larger than a lateral cross-sectional dimension of the hole  42 . The retaining ring  40  further includes an engagement member for secure engagement with the housing  16  of the electronic device  12 . For example, the engagement member allows the retaining ring  40  to securely engage the housing  16  within a channel thereof. The engagement member can be the same as, similar to, or different from an engagement member of the housing connector  30 . 
     According to some embodiments, for example as shown in  FIG. 5 , the engagement surface  28  extends between the housing connector  30  and the stopper  50 . The engagement surface  28  includes the loop zone  52  and the hook zone  54 . The loop zone  52  can extend closer to the housing connector  30 , and the hook zone  54  can extend closer to the stopper  50 . Along the loop zone  52 , the engagement surface  28  provides loops extending from the base  32  for engagement with hooks of the hook zone  54 . The hook zone  54  can include one or more hook pads  56  attached to the base  32  and for engagement with the loops of the loop zone  52 . 
     As shown in  FIGS. 4 and 5 , the portion of the contact surface  26  having loops can have a greater area than the area of the loop zone  52  of the engagement surface  28 . For example, the contact surface  26  can have loops along an entire length thereof between the housing connector  30  and the stopper  50 . The engagement surface  28  can be divided between the loop zone  52  and the hook zone  54 . 
     According to some embodiments, for example as shown in  FIG. 6 , the watchband  20  slidably extends through the retaining ring  40 . The length of the watchband  20  that extends on either side of the retaining ring  40  can be adjusted as desired by a user for preferred comfort and grip on the wrist  2  of the user. A stopper  50  can be sized and arranged to prevent passage through the retaining ring  40  so that a portion of the watchband  20  remains within at least a portion of the retaining ring  40 . The stopper  50  can include features on an end of the outer portion  24 , along the outer portion  24 , on the engagement surface  28 , and/or on the contact surface  26 . 
     According to some embodiments, for example as shown in  FIGS. 7 and 8 , the stopper  50  is assembled with a spring element to securely engage the base  32  of the watchband  20 . The base  32  can include an engagement section  34  with which one or more portions of a shell  154  can engage. For example, one or more teeth of the shell  154  extend into holes of the engagement section  34 . A bow spring  156  is provided between the shell  154  and an insert  152 . When the insert  152  is placed over the shell  154 , the insert  152  prevents the shell  154  from disengaging from the engagement section  34 . When the bow spring  156 , within the insert  152 , extends to a relaxed position, the bow spring  156  prevents the insert  152  from sliding off of the shell  154 . A cover  150  can be provided (e.g., overmolded) over at least a portion of the insert  152 . 
     According to some embodiments, for example as shown in  FIGS. 9 and 10 , the stopper  50  is assembled with pins to securely engage the base  32  of the watchband  20 . The base  32  can include an engagement section  34  with which one or more pins  166  can engage. For example, one or more pins  166  can extend through holes of the engagement section  34 , through holes of a shell  168 , and/or holes of an insert  162 . The shell  168  can fit within at least a portion of the insert  162 . The pins  166  prevent the engagement section  34  from disengaging longitudinally away from the insert  162  and/or the shell  168 . One of more covers  164  can be provided (e.g., overmolded, adhered, snapped) over at least a portion of the insert  162  and/or the shell  168  to keep the pins  166  from moving out of the insert  162  and/or the shell  168 . 
     According to some embodiments, for example as shown in  FIGS. 11-13 , the stopper  50  is molded onto the base  32 . The stopper  50  can include one or more protrusions  198  that provide a cross-sectional dimension that is greater than a hole  42  of the retaining ring  40 . The base  32  can include an engagement section  34  with which one or more portions of the stopper  50  can engage. As shown in  FIG. 12 , the engagement section  34  can include holes. As shown in  FIG. 13 , the engagement section  34  can include notches. The stopper  50  can be overmolded onto the engagement section  34  of the base  32 , such that a portion of the stopper  50  extends into voids of the engagement section  34  for secure engagement thereof. 
     According to some embodiments, for example as shown in  FIG. 14 , the watchband  20  includes loops  80  above the base  32 . The loops  80  can be formed by loop threads that extend from and return to the base  32 . Each of the loop threads can be woven into the base  32  and extend onto or beyond the contact surface  26  and the engagement surface  28 . The base  32  can be formed from base threads  60  and/or elastic threads  72 . The elastic threads  72  extend longitudinally, for example toward the housing connector  30  and the stopper  50 . The base threads  60  extend transverse to the elastic threads  72  and/or the loop threads. The elastic threads  72  turn and reverse direction at one or more ends of the base  32 . 
     As used herein, a loop is defined by a length of a structure that surrounds a closed space. A loop can be formed by a thread even when the thread does not connect to itself to surround the closed space. For example, a “loop” of thread can extend from a base and return to the base, such that the thread and the base together surround a closed space. 
     Materials selected for the threads can be selected to facilitate the manufacture and use described herein. The threads can include natural and/or synthetic fibers. The threads can include a polymer, copolymer, or polymer blend. The threads can include nylon, polyester, polyurethane, and combinations thereof, including spandex. The threads can include single filaments and/or a bundle of yarn. The elastic threads  72  can be of a material that facilitates stretching. The base threads  60  and the loop threads can be of the same or a similar material. The base threads  60  can have a melting point that is lower than a melting point of the loop threads. 
     According to some embodiments, for example as shown in  FIG. 15 , one or more engagement loop threads are used to form engagement loops  80  on the engagement surface  28 . The engagement loops  80  are formed and arranged to enhance engagement with hooks. For example, the shape, size, number, and distribution of the engagement loops  80  can facilitate ready and secure engagement with hooks. Such features are provided with a weave by which the engagement loops  80  are formed. 
     As shown in  FIG. 15 , first engagement loop threads  82 , second engagement loop threads  84 , and third engagement loop threads  86  are woven into the same base  32 . The first engagement loop threads  82 , the second engagement loop threads  84 , and the third engagement loop threads  86  are separate threads or segments of one or more continuous threads. At least some segments of the engagement loop threads, including the engagement loops  80 , extend in parallel to each other along the base  32 . 
     As shown in  FIG. 15 , a first engagement loop thread  82  forms an engagement loop  80  extending away from the engagement surface  28  of the base  32  and along a longitudinal length. The longitudinal length of the engagement loop  80  corresponds to a number of base threads  60  between the locations at which the engagement loop  80  extends from the base  32 . For example, as shown in  FIG. 15 , the engagement loops  80  extend longitudinally across five base threads  60  (i.e., referring to a combined number of base threads  60  on opposite surfaces of the base  32 ). Other longitudinal lengths and numbers of skipped base threads  60  can apply to characterize the engagement loop  80 , as described further herein. For example, an engagement loop thread can form an engagement loop  80  that extends across 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 base threads  60 . 
     Between each engagement loop  80 , the first engagement loop thread  82  extends alternatingly between and/or beyond opposing surfaces (i.e., the contact surface  26  and the engagement surface  28 ) of the base  32 . At each of the surfaces, the first engagement loop thread  82  extends at least partially about a base thread  60  and turn to reenter the base  32 . The first engagement loop thread  82  turns and returns to the base  32  without forming an engagement loop  80  or extending longitudinally in a manner that skips any base threads  60 . In such an arrangement, the turn of the first engagement loop thread  82  is against the base  32 , rather than elevated away from the base  32  as an engagement loop  80 . The extent of the first engagement loop thread  82  between adjacent engagement loops  80  corresponds to a number of consecutive base threads  60  about which the first engagement loop thread  82  turns. For example, as shown in  FIG. 15 , the first engagement loop thread  82  can turn about seven consecutive base threads  60  between adjacent engagement loops  80 . Other numbers of contacted base threads  60  can apply to characterize the first engagement loop thread  82 , as described further herein. For example, an engagement loop thread can turn about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or more than 14 consecutive base threads  60  between adjacent engagement loops  80 . 
     As shown in  FIG. 15 , different threads are staggered, such that the engagement loops  80  of one thread are formed at different longitudinal locations than the engagement loops  80  of another thread. For example, engagement loops  80  of the first engagement loop thread  82  can be formed at a longitudinal location that is different from the location of the engagement loops  80  formed by the second engagement loop thread  84 . Furthermore, engagement loops  80  of the third engagement loop thread  86  can be formed at a longitudinal location that is different from the location of the engagement loops  80  formed by the first engagement loop thread  82  and the location of the engagement loops  80  formed by the second engagement loop thread  84 . Such an arrangement allows the engagement loops  80  to be distributed farther away from each other, so that greater opportunities for engagement with hooks are provided. Accordingly, the engagement loops  80  of one thread extend across a set of base threads  60  that is different than the set of base threads  60  across which engagement loops  80  of another thread extend. Additionally, the engagement loops  80  of one thread turn about a set of consecutive base threads  60  that is different than the set of consecutive base threads  60  about which another thread turns. 
     According to some embodiments, for example as shown in  FIG. 16 , one or more contact loop threads are used to form contact loops  90  on the contact surface  26 . The contact loops  90  are formed and arranged to enhance contact with the wrist  2  of the user. For example, the shape, size, number, and distribution of the contact loops  90  facilitate comfort, breathability, and moisture wicking capabilities for the user. Such features can be provided with a weave by which the contact loops  90  are formed. 
     As shown in  FIG. 16 , first contact loop threads  92  and second contact loop threads  94  can be woven into the same base  32 . The first contact loop threads  92  and the second contact loop threads  94  can be separate threads or segments of one or more continuous threads. At least some segments of the contact loop threads, including the contact loops  90 , extend in parallel to each other along the base  32 . 
     As shown in  FIG. 16 , a first contact loop thread  92  forms a contact loop  90  extending away from the contact surface  26  of the base  32  and along a longitudinal length. The longitudinal length of the contact loop  90  corresponds to a number of base threads  60  between the locations at which the contact loop  90  extends from the base  32 . For example, as shown in  FIG. 15 , the contact loops  90  extend longitudinally across five base threads  60  (i.e., referring to a combined number of base threads  60  on opposite surfaces of the base  32 ). Other longitudinal lengths and numbers of skipped base threads  60  can apply to characterize the contact loop  90 , as described further herein. For example, a contact loop thread can form a contact loop  90  that extends across 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 base threads  60 . 
     The longitudinal length of one or more of the engagement loops  80  can be the same or different than the longitudinal length of one or more of the contact loops  90 . For example, the lengths can be uniform for both the engagement loops  80  on the engagement surface  28  and the contact loops  90  on the contact surface  26 . Alternatively or in combination, the loops can have different sizes to accommodate the different functions of contacting the user and engaging hooks. 
     Between each contact loop  90 , the first contact loop thread  92  extends alternatingly between and/or beyond opposing surfaces (i.e., the contact surface  26  and the engagement surface  28 ) of the base  32 . At each of the surfaces, the first contact loop thread  92  extends at least partially about a base thread  60  and turn to reenter the base  32 . The first contact loop thread  92  turns and returns to the base  32  without forming a contact loop  90  or extending longitudinally in a manner that skips any base threads  60 . In such an arrangement, the turn of the first contact loop thread  92  is against the base  32 , rather than elevated away from the base  32  as a contact loop  90 . The extent of the first contact loop thread  92  between adjacent contact loops  90  corresponds to a number of consecutive base threads  60  about which the first contact loop thread  92  turns. For example, as shown in  FIG. 16 , the first contact loop thread  92  turn about 3 consecutive base threads  60  between adjacent contact loops  90 . Other numbers of contacted base threads  60  can apply to characterize the first contact loop thread  92 , as described further herein. For example, a contact loop thread can turn about 2, 3, 4, 5, 6, 7, 8, or more than 8 consecutive base threads  60  between adjacent engagement loops  80 . 
     The number of turns between adjacent engagement loops  80  can be the same or different than the number of turns between adjacent contact loops  90 . For example, the number of turns can be different to accommodate the different functions of contacting the user and engaging hooks. The number of turns between adjacent engagement loops  80  can be greater than the number of turns between adjacent contact loops  90 , so that the engagement loops  80  remain more securely fixed throughout multiple hook engagement and disengagement actions. A lower number of turns between adjacent contact loops  90  can also yield a greater density of contact loops  90  in a given area of the base  32 . For example, where the engagement loops  80  and the contact loops  90  have the same or substantially equal lengths, the lower number of turns between adjacent contact loops  90  produces a greater number of contact loops  90  than engagement loops  80  in a given area. The higher density of contact loops  90  provides greater comfort for the user by distributing forces across the greater number of contact loops  90 . 
     As shown in  FIG. 16 , different threads can be staggered, such that the contact loops  90  of one thread are formed at different longitudinal locations than the contact loops  90  of another thread. For example, contact loops  90  of the first contact loop thread  92  can be formed at a longitudinal location that is different from the location of the contact loops  90  formed by the second contact loop thread  94 . Such an arrangement allows the contact loops  90  to be distributed farther away from each other, so that forces and pressure on the wrist  2  of the user is more evenly distributed. Accordingly, one thread can extend across a set of base threads  60  that is different than the set of base threads  60  across which contact loops  90  of another thread extend. Additionally, one thread can turn about a set of consecutive base threads  60  that is different than the set of consecutive base threads  60  about which another thread turns. 
     One or more of the engagement loops  80  and one or more of the contact loops  90  can be segments of a continuous thread. For example, a single thread can extend through the base  32  to form loops on both the engagement surface  28  and the contact surface  26 . By further example, a single thread can form engagement loops  80  on the engagement surface  28  between ends of the base  32 , turn to reverse direction, and form contact loops  90  on the contact surface  26  between the ends of the base. 
     According to some embodiments, the engagement loops  80  and the contact loops  90  are formed and secured by a weaving process. The base  32  can be stretched longitudinally to increase the longitudinal spacing between the base threads  60 . The elastic threads  72 , extending longitudinally, can facilitate the stretching based on elastic properties of the elastic threads  72 . The loop threads can be woven into the base  32  as described herein while the base  32  is in the stretched configuration. When the base  32  returns to a non-stretched or relaxed configuration, the engagement loops  80  and the contact loops  90  become elevated from the base  32  due to the shortening between the locations at which the engagement loops  80  and the contact loops  90  extend from the base  32 . The loop threads and the base  32  can be heated, such that at least the base threads  60  at least partially melt to fuse and bond to the loop threads that contact and turn about the base threads  60 . Thus, a secure engagement between the loop threads and the base threads  60  is achieved. The strength of the bond can be proportionate to the number of turns made by the loop threads about the base threads  60 . 
     The watchband can be made in a variety of colors with visual effects that occur based on the design described herein. At least some of the contact loop threads, the engagement loop threads, the contact base threads, and the engagement base threads can be of different colors that other threads in the watchband  20 . The several threads can be combined to produce custom color combinations as desired. The colors can be selected based on the appearance of certain threads in the weaving patterns described herein. Furthermore, because portions of the threads are elevated away from a surface, the weaving pattern produces different visual effects when viewed at different angles. For example, at some viewing angles, rows of the loops present themselves visually while blocking views of many of the base threads. At these angles, the color selected for the loop threads is relatively more prominent. At other viewing angles, the base threads are viewed more easily. At these angles, the color selected for the base threads is relatively more prominent. As such, the apparent color, pattern, and design changes as the watchband  20  is viewed from different angles. 
     According to some embodiments, for example as shown in  FIG. 17 , a hook pad  56  can include one or more hooks  58  for engagement with loops. The hooks  58  can be distributed across a surface of the hook pad  56 . The number, density, size, and/or shape of the hooks  58  can be consistent or vary across the surface of the hook pad  56 . The perimeter of the hook pad  56  can include one or more curves to reduce sharpness of the edges. 
     According to some embodiments, for example as shown in  FIG. 18 , a hook pad  56  includes a transition from a top surface to a bottom surface that reduces sharp edges. For example, the hook pad  56  can include an edge region  62  along a periphery of the hook pad  56 . The edge region  62  can include one or surface features that provide a transition. For example as shown in  FIG. 18 , the hook pad  56  can include a round bevel. Other shapes and geometries can be provided. For example, the edge region  62  can include one or more chamfers, fillets, scallops, undulations, and/or textures. The edge region  62  reduces sharpness relative to a right angle corner or edge. The transition provided by the edge region  62  provides comfort upon contact with the user and avoid catching on objects. According to some embodiments, the hook pad  56  is formed from a sheet that includes hooks  58 . The hook pad  56  can be cut from the sheet, for example with a die cut. The edge region  62  can be formed by cutting or molding regions of the hook pad  56  to have the desired shape. 
     The number, density, size, and/or shape of the hook pads  56  can be consistent or vary across the surface of the hook zone  54 . The hook pads  56  can be attached to the base  32  by one or more of welding (e.g., laser welding), lamination, adhesion, interweaving, or combinations thereof. 
     According to some embodiments, for example as shown in  FIGS. 19 and 20 , multiple hook pads  56  are provided along a hook zone  54  of a watchband  20 . The hook zone  54  is adjacent to a loop zone  52  of the watchband  20 . The hook zone  54  provides a length of the base  32  without loops extending therefrom. The hook zone  54  can be adjacent to the stopper  50 . Each of the hook pads  56  is longitudinally spaced apart from one or longitudinally adjacent hook pads  56 . The interruptions between hook pads  56  provide greater flexibility than would be provided with a continuous length of one or more hook pads  56 . Accordingly, the hook zone  54  has an overall greater flexibility with the interruptions. One or more hook pads  56  at or near a terminal end of the watchband  20  can provide enhanced engagement. For example, an endmost one of the hook pads  56  can be larger than other hook pads  56  located within the hook zone  54  at greater distances from the stopper  50 . Other features can be provided, such as a different number, density, distribution, size, and/or shape of hooks on one or more hook pads  56  at or near a terminal end of the watchband  20  as compared to the other hook pads  56 . The distinct features of the endmost hook pad  56  can provide stronger engagement near the terminal end of the watchband  20  to resist forces that would disengage the watchband  20  from itself. A greater number of hook pads  56  with small interruptions can also provide flexibility, with a greater surface area of the hook zone  54  being occupied by hook pads  56 . 
     According to some embodiments, for example as shown in  FIGS. 21 and 22 , the stopper  50  includes an engagement element  64 . Alternatively to or in combination with the hook pads  56  on the base  32  along the hook zone  54 , the engagement element  64  of the stopper  50  can include hooks or another feature for engaging another portion of the watchband  20 . The engagement element  64  can be attached to the stopper  50  by one or more of welding (e.g., laser welding), lamination, adhesion, interweaving, or combinations thereof. Hooks of the engagement element  64  can engage to loops of the loop zone  52 . The engagement element  64  of the stopper  50  can be larger than hook pads  56  located within the hook zone  54 . Other features can be provided, such as a different number, density, distribution, size, and/or shape of hooks on the engagement element  64  as compared to the hook pads  56 . The distinct features of the engagement element  64  provide stronger engagement for the stopper  50  to resist forces that would otherwise disengage the stopper  50  from engagement with other portions of the watchband  20 . Alternatively or in combination, the engagement element  64  can include a magnet, a clasp, or another mechanism to releasably engage another portion of the watchband  20 . The engagement element  64  of the stopper  50  advantageously provides engagement near the terminal end of the watchband  20 . This arrangement helps facilitate engagement along a greater extent of the watchband  20 . Furthermore, forces acting on the stopper  50  are resisted to keep the stopper  50  engaged with other portions of the watchband  20 . 
     According to some embodiments, for example as shown in  FIG. 23 , a hook section  66  is positioned at or near a terminal end of the watchband  20 . The stopper  50  can be positioned between the hook zone  54  and the hook section  66 . Both the hook zone  54  and the hook section  66  can include one or more hook pads  56 . Accordingly, the hooks on both the hook zone  54  and the hook section  66  provide engagement with other portions of the watchband  20  (e.g., loops). The hook section  66  advantageously provides engagement near the terminal end of the watchband  20  to resist forces that would disengage the watchband  20  from itself. 
     According to some embodiments, for example as shown in  FIGS. 24 and 25 , a capture band  110  retains the stopper  50  when inserted therein. The capture band  110  stretches and/or deforms elastically to receive the stopper  50  and/or the outer portion  24  of the watchband  20 . As shown in  FIGS. 24 and 25 , a user can insert at least the stopper  50  through a portion of the capture band  110 . The capture band  110  then encompasses a portion of the inner portion  22  and the outer portion  24 . In such an arrangement, the capture band  110  provides additional support to keep the outer portion  24  engaged with and/or in contact with the inner portion  22 . The capture band  110  is slideable along a longitudinal length of the inner portion  22  and/or the outer portion  24 . For example, the capture band  110  can receive the stopper  50  and be adjusted to be near the stopper  50 . The capture band  110  is resilient and sized to press the outer portion  24  and the inner portion  22  together. The user can remove the stopper  50  and the outer portion  24  from the capture band  110  by sliding the capture band  110  relative to the outer portion  24  and the stopper  50 . 
     According to some embodiments, for example as shown in  FIGS. 26-45 , a slideable shield  112  retains the stopper  50  when connected thereto. The slideable shield  112  is adjustable to be aligned with the stopper  50 . For example, as shown in  FIG. 27 , a user can apply the outer portion  24  to the inner portion  22 , bringing the stopper  50  into close proximity with the inner portion  22 . As shown in  FIG. 28 , the slideable shield  112  is slideable along the inner portion  22  to be aligned with the stopper  50 . The slideable shield  112  can be in contact with the stopper  50  and/or extend over at least a portion of the stopper  50 . In such an arrangement, the slideable shield  112  provides additional support to keep the stopper  50  engaged with and/or in contact with the inner portion  22 . Forces that would otherwise pull the stopper away from the inner portion  22  are deflected by the shielding provided by the slideable shield  112 . For example, the stopper  50  and the slideable shield  112  can include a mechanism (e.g., magnets, hook and loop, clasp) that facilitates engagement between the stopper  50  and the slideable shield  112 . The user can remove the stopper  50  from the slideable shield  112  by sliding the slideable shield  112  and the stopper  50  away from each other. 
     According to some embodiments, for example as shown in  FIG. 29 , a slideable receptacle  116  retains the stopper  50  when connected thereto. The slideable receptacle  116  is adjustable to be aligned with the stopper  50 . For example, as shown in  FIG. 29 , a user can apply the outer portion  24  to the inner portion  22 , bringing the stopper  50  into close proximity with the inner portion  22 . The slideable receptacle  116  is slideable along the inner portion  22  to be aligned with the stopper  50 . The slideable receptacle  116  and the stopper  50  can have complementary shapes, so that the stopper  50  fits tightly within the slideable receptacle  116  when pressed therein. For example, the stopper  50  can be slightly oversized with respect to the slideable receptacle  116 . Alternatively or in combination, the slideable receptacle  116  and the stopper  50  can have complementary features, such as a button coupling including a socket and a stud, so that the stopper  50  can snap into place with the slideable receptacle  116  when pressed together. When engaged, the slideable receptacle  116  provides support to keep the stopper  50  engaged therein. The user can remove the stopper  50  from the slideable receptacle  116  by applying a force sufficient to overcome the engagement. 
     According to some embodiments, for example as shown in  FIGS. 30-32 , a cover strap  35  retains the stopper  50  and the outer portion  24  against the inner portion  22 . The cover strap  35  extends from the housing  16  of the electronic device  12 , the housing connector  30 , another structure opposite the retaining ring  40 , and/or another portion of the watchband  20 . The cover strap  35  can include hook pads  36  for engaging loops of the outer portion  24 . For example, as shown in  FIG. 31 , a user can apply the outer portion  24  to the inner portion  22 , bringing the stopper  50  into close proximity with the inner portion  22 . As shown in  FIG. 32 , the cover strap  35  is applied to an outer surface of the outer portion  24 . The cover strap  35  can extend over the stopper  50  and at least a portion of the outer portion  24 . The hook pads  36  of the cover strap  35  can engage loops on an outer surface of the outer portion  24 . In such an arrangement, the cover strap  35  provides additional support to keep the stopper  50  engaged with and/or in contact with the inner portion  22 . Forces that would otherwise pull the stopper away from the inner portion  22  are deflected by the shielding provided by the cover strap  35 . Furthermore, forces that would tend to pull the cover strap  35  away from the outer portion  24  would tend not to pull the stopper  50  away from the inner portion  22 . The user can remove the cover strap  35  from the outer portion  24  by pulling the sufficient force to disengage the hook pads  36  from the loops on the outer surface of the outer portion  24 .
