[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application No. 63 / 295,395, entitled "Reel Based Closure System," filed on December 30, 2021, the disclosure of which is incorporated by reference herein in its entirety for all purposes as if fully set forth herein.
[0002]
[0002] The present disclosure relates to reel-type closure devices for various articles, such as orthotics, medical devices, shoes, garments, apparel, and the like. Such articles typically include some sort of closure system that allows the article to be placed and closed or fastened around a body part. The closure system is typically used to maintain or secure the article around the body part. For example, a shoe is typically placed over an individual's foot and shoe laces are pulled and tied to close and secure the shoe around the foot. Similarly, an orthotic is typically attached around the body and closed or fastened by a hook-and-loop fastener or similar mechanism.
[0003]
[0003] Traditional closure systems have been improved in an effort to increase the fit and / or comfort of the article around a body part. For example, shoe lacing configurations and / or patterns have been improved in an attempt to increase the fit and / or comfort of wearing a shoe. Traditional closure systems have also been improved in an effort to reduce the time it takes to close and secure an article around a body part. These improvements have resulted in the use of various tension cords, straps, and tightening devices that allow the article to be quickly closed and secured around the wearer's body. Summary of the Invention
[0004]
[0004] The embodiments described herein generally relate to reel-type closure devices and wearable appliances. According to one aspect, the reel-type closure device includes a housing, a spool rotatably disposed within the housing, and a knob that operably couples to the spool such that rotation of the knob also rotates the spool. Additionally, the reel-type closure device includes a pawl component having one or more pawl arms that include a proximal end coupled to the pawl component and a distal end including one or more pawl teeth. The pawl component includes a lip or wall, and the pawl arm includes a protrusion or tab that engages the lip or wall of the pawl component to control radial movement of the pawl arm relative to the pawl component.
[0005]
[0005] The pawl component is generally disc-shaped, although other shapes may be utilized. A lip or wall of the pawl component is generally formed or defined on an outer periphery of the pawl component. A protrusion or tab of the pawl arm is typically formed on a radially inner edge of the pawl arm. In certain cases, the protrusion or tab is located at a distal end of the pawl arm. One or more pawl teeth of the pawl arm are configured to engage the teeth of the reel closure device when the knob is in an engaged position. The one or more pawl teeth are disengaged from the teeth of the reel closure device when the knob is in a disengaged position. The knob is generally axially movable relative to the housing between an engaged position and a disengaged position. A proximal end of the pawl arm is typically fixedly coupled to or attached to the pawl component. The pawl component is typically a separate component from the knob.
[0006] A method of assembling a reel closure device can include obtaining a housing and disposing a spool within the housing such that the spool is rotatable within the housing. The method can include coupling a pawl component to the housing and coupling a knob to the housing such that the knob is operably coupled to the spool. The pawl component can include one or more pawl arms having a proximal end coupled to the pawl component and a distal end including one or more pawl teeth. The pawl component can include a lip or wall and the pawl arm can include a protrusion or tab that engages the lip or wall of the pawl component to control radial movement of the pawl arm relative to the pawl component.
[0007] In some cases, the method may further include disposing a protrusion or tab of the claw arm radially inward of a lip or wall of the claw component such that radially outward movement of the claw arm causes the protrusion or tab of the claw arm to engage the lip or wall of the claw component. The method may further include axially inserting the claw component into a lower end of the knob and / or attaching the reel closure device to the footwear.
[0008] According to another aspect, a spool for a reel-type closure device includes an upper flange, a lower flange, and a central body formed, disposed, or defined between the upper and lower flanges. The central body can be configured such that a tension member can be wound around the central body as the spool rotates in a first direction and unwound from the central body as the spool rotates in a second direction. A channel or recess extends within the central body. The channel or recess can extend through the central body from one side of the central body to an opposite side of the central body. A cross-sectional profile of the central body taken or observed along a plane perpendicular to a central axis of the spool is non-circular or asymmetric. The plane can intersect the central body approximately midway along the central axis of the spool.
[0009] In some cases, the spool includes a single channel or recess. In other cases, the channel or recess may be a first channel or recess and the spool may include a second channel or recess. The first channel or recess and the second channel or recess may be located on either side of a central opening of the spool. The central body of the spool may have an oval profile. The cross-sectional profile of the central body may have a linear portion or segment. In some cases, the linear portion or segment is a first linear portion or segment and the cross-sectional profile may have a second linear portion or segment separate from the first linear portion or segment. The second linear portion or segment may have a shorter length than the first linear portion or segment. A majority of the cross-sectional profile of the central body may be circular. A portion of the cross-sectional profile of the central body adjacent to the channel may have a triangular shape.
[0010]
[0010] A method of assembling a reel closure device may include obtaining a spool having a non-circular or asymmetric shape as described above, and inserting the spool into a housing of the reel closure device such that the spool is rotatable within the housing. The method may further include coupling a tension member to a channel or recess to attach the tension member to the spool. Coupling the tension member to the channel or recess may include inserting the tension member through the channel or recess and tying a knot in the tension member, or attaching a stop component to the tension member and retracting the stop component into the channel or recess. The method may further include attaching the reel closure device to footwear.
[0011] According to another aspect, a reel-type closure device includes a housing, a spool, a knob rotatably coupled to the housing, and a drive component operably coupled to the knob and the spool such that rotation of the knob rotates the spool in a tightening direction. The spool includes a channel about which the tension member is wound as the spool rotates in the tightening direction. Additionally, the spool includes a plurality of teeth configured to engage a plurality of teeth on the drive component. The teeth on the spool and the drive component typically extend axially in opposing directions. The angle of the mating surfaces or faces of each tooth on the spool or the drive component varies along the length of the respective tooth.
[0012]
[0012] The mating surface or face of each tooth of the spool or the drive component may include a first portion or region and a second portion or region. The first portion or region may be angled relative to the second portion or region. For example, the second portion or region may be more perpendicularly oriented relative to a central axis of the reel closure device than the first portion or region. In some cases, the angle of the mating surface or face of each tooth of the spool and the angle of the mating surface or face of each tooth of the drive component vary along the length of the respective teeth such that the teeth of both the spool and the drive component have angles that vary along the length of the respective teeth.
[0013]
[0013] The plurality of teeth of the spool may be disposed on an upper surface of the spool, and the plurality of teeth of the drive component may be disposed on a lower surface of the drive component. The drive component may be axially movable relative to the spool between an engaged position in which the teeth of the drive component engage the teeth of the spool and a disengaged position in which the teeth of the drive component disengage from the teeth of the spool. The reel-type closure device may further include a plurality of pawls configured to engage the teeth of the reel-type closure device to prevent rotation of the spool in an uncoiling direction. Each pawl of the plurality of pawls may include a pawl arm having a proximal end coupled to the drive component and a distal end including one or more pawl teeth.
[0014]
[0014] A method of assembling a reel closure device includes providing a housing, disposing a spool within the housing, operably coupling a drive component to the spool, and coupling a knob to the housing such that rotation of the knob rotates the spool in a tightening direction. As discussed above, the angle of the interlocking surfaces or faces of each tooth on the spool or the drive component may vary along the length of the respective tooth. The method may further include attaching the reel closure device to footwear.
[0015] According to another aspect, a reel-type closure device includes a housing having an inner wall and a plurality of channels or recesses formed or defined in the inner wall, a spool disposed within the housing, and a knob operatively coupled to the spool for rotating the spool in a tightening direction. The spool includes channels about which a tension member is wound as the spool rotates in the tightening direction within the housing. The plurality of channels or recesses formed or defined in the inner wall of the housing extend axially along the inner wall and define surfaces located between adjacent channels. The spool at least momentarily contacts one or more of the defined surfaces as the spool rotates in the tightening direction within the housing.
[0016]
[0016] The housing may have an open lower end. In such a case, each channel or recess may extend to the open lower end of the housing. The housing may include an annular rib formed or defined on an inner wall between the upper and lower portions of the housing. In such a case, each channel or recess may extend to the annular rib. The reel-type closure device may include 4 to 20 channels or recesses. Additionally, the reel-type closure device may include a pawl component including one or more pawls. The pawl component may be configured to prevent rotation of the spool in an uncoiling direction. The reel-type closure device may further include a base disposed axially below the spool and releasably attachable to the lower end of the housing.
[0017] A method of assembling a reel closure device includes providing a housing having an inner wall and a plurality of channels or recesses formed in the inner wall. A spool is disposed within the housing, and a knob is operatively coupled to the housing and the spool such that rotation of the knob rotates the spool in a tightening direction. As described above, the plurality of channels or recesses extend axially along the inner wall of the housing and define surfaces located between adjacent channels. The spool at least momentarily contacts one or more of the defined surfaces as the spool rotates in the tightening direction within the housing. The method may further include attaching the reel closure device to footwear.
[0018] According to another aspect, a strap for use with a reeled closure device includes a proximal end, a distal end, an intermediate portion located between the proximal and distal ends, and a window or elongated channel formed or defined in the intermediate portion of the strap. The window or elongated channel can be positioned over the reeled closure device in a manner that allows the strap to be moved relative to the reeled closure device while the intermediate portion of the strap completely surrounds the reeled closure device.
[0019]
[0019] The window or elongated channel typically has a longitudinal length greater than the length or diameter of the reel-type closure device. The window or elongated channel typically has a transverse width greater than the width or diameter of the reel-type closure device. The strap may be longitudinally movable relative to the reel-type closure device while the intermediate portion of the strap completely encircles the reel-type closure device. The intermediate portion of the strap may be reinforced relative to the proximal and distal ends of the strap. In certain cases, a reinforcing material or layer may be bonded to the intermediate portion of the strap at or near the window or elongated channel. The proximal and / or distal ends of the strap may be formed of an elastic or semi-elastic material. The strap may further comprise a fastening mechanism that allows the strap to be fastened to another strap or other material. Specific examples of fastening mechanisms include hook-and-loop fasteners, clamps, buckles, snaps, magnetic fasteners, and the like, or combinations thereof. The strap may be used to close and / or fasten an article. A specific example of an article that may be particularly suitable for a strap is a brace, such as an ankle brace. The strap may be attached to the bottom end of the ankle brace.
[0020]
[0020] A method of manufacturing a brace includes providing a brace, attaching a reeled closure device to the brace, and coupling a strap to the brace. As described above, the strap includes a proximal end, a distal end, an intermediate portion located between the proximal and distal ends, and a window or elongated channel formed or defined in the intermediate portion of the strap. The window or elongated channel can be positioned over the reeled closure device such that the strap can be moved around the brace and relative to the reeled closure device while the intermediate portion of the strap completely surrounds the reeled closure device.
[0021] In certain cases, the brace is an ankle brace. In such cases, coupling the strap to the brace can include attaching the strap to a lower end of the ankle brace such that a portion of the strap lies below the wearer's foot when the ankle brace is placed around the wearer's foot.

[0024]
[0031] In the accompanying drawings, similar components and / or features may have the same numerical reference designation. Furthermore, various components of the same type may be distinguished by following the reference designation with a letter that distinguishes the similar components and / or features. When only a leading numerical reference designation is used in the specification, the description also applies to any similar components and / or features that have the same leading numerical reference designation regardless of any trailing letters.
[0025]
[0032] The following description provides only exemplary embodiments and is not intended to limit the scope, applicability, or configuration of the present disclosure. Rather, the following description of exemplary embodiments provides those skilled in the art with an enabling description for implementing one or more exemplary embodiments. It will be understood that various changes can be made in the function and arrangement of elements without departing from the spirit and scope of the invention, as set forth in the appended claims.
[0026]
[0033] 1A-5 provide a reel-type closure device (hereinafter closure system or reel-type device / system) that can be used to fasten an article or other item by pulling a string or tension member. The article can be a variety of items including packs (i.e., backpacks, book bags, etc.), apparel (i.e., hats, gloves, belts, etc.), sports apparel (i.e., boots, snowboard boots, ski boots, etc.), medical braces (i.e., back braces, knee braces, wrist braces, ankle braces, etc.), as well as various other items or apparel. Particular embodiments in which the closure system can be used include footwear such as shoes, boots, sandals, etc.
[0027]
[0034] 1A-5, an embodiment of a reel-type closure device 100 is shown that can be used to fasten articles such as shoes, boots, or other footwear. Additionally, the reel-type closure device 100 may be used to fasten other non-footwear articles such as backpacks, helmets, jackets, and the like. The reel-type closure device 100 can be used to fasten essentially anything that is closed and / or fastened via tension members, cords, strings, ropes, and the like. While FIG. 1A shows an assembled view of the reel-type closure device 100, FIG. 1B shows a cross-sectional view of the reel-type closure device, and FIG. 1C shows an exploded perspective view of the reel-type closure device 100. Various internal components are shown in the views of FIG. 1B and FIG. 1C.
[0028]
[0035] The reel closure device 100 includes a housing 110 having an interior region in which various components of the reel closure device 100 are disposed. For example, a spool 120 is disposed in the interior region of the housing 110. The spool 120 is rotatable in a first direction in the interior region of the housing to wind a tension member (not shown) around the spool, and in a second direction in the interior region of the housing 110 to unwind the tension member from around the spool 120. The spool 120 typically includes an annular channel or central cylinder about which the tension member is wound and unwound. A knob 102 is operably coupled to the spool 120 and the housing 110. The knob 102 can be rotated by a user in a tightening direction to wind the tension member around the spool 120 by rotating the spool 120 in a first direction. In some embodiments, the knob can also be rotated by a user in a loosening direction to unwind the tension member from around the spool 120 by rotating the spool 120 in a second direction. The tightening direction is typically the same rotational direction as the first direction (e.g., clockwise), but in some cases the tightening direction may be the opposite direction to the first direction. Similarly, the loosening direction is typically the same rotational direction as the second direction (e.g., counterclockwise), but in some cases the loosening direction may be the opposite direction to the second direction. For convenience in describing the reel-type closure device 100, the spool 120 is described below as being rotatable in the tightening direction to wind up the tension member and in the loosening direction to unwind the tension member. Other components of the reel-type closure device 100 include a pawl disk 140, a seat component 130 (also referred to herein as a base component), and a base member 104.
[0029]
[0036] The housing 110 can be disposed within a base member 104 or bayonet (hereinafter, base member 104) that can be attached to an article. When the housing 110 is coupled to the base member 104, a pair of lanyard ports 112 of the housing 110 are disposed within corresponding openings or windows 106 of the base member 104. By disposing the lanyard ports 112 within the openings 106 of the base member 104, the reel-type closure device 100 can have a more seamless appearance. The lanyard ports 112 provide access to the interior for the tension member, allowing access to the spool of tension member so that the tension member can be wound around and unwound from the spool. Additionally, the housing 110 includes an inner annular ridge 116 that surrounds the interior region of the housing 110 and divides the interior region into an upper portion and a lower portion. In some embodiments, the inner annular ridge 116 functions to prevent components located at the bottom of the housing from moving upwards and to prevent components located at the top of the housing from moving downwards.
[0030]
[0037] The housing 110 further includes recesses or teeth 118 configured to engage one or more teeth of the pawl disk 140. The teeth 118 may be formed on an inner surface of the housing 110 such that the teeth 118 face radially inward, as shown in FIG. 1C. In other cases, the teeth 118 may be formed on a top surface of the housing 110 such that the teeth 118 face axially upward (not shown). In still other cases, the teeth 118 may be formed on a separate component (not shown) that can be coupled to the housing 110. The teeth 118 may face axially or radially as desired on this separate component. The teeth 118 may have a triangular configuration or may be formed from voids or openings similar to the teeth 138 of the base or seat component 130 (hereinafter seat component 130).
[0031]
[0038] The housing 110 includes a coupling feature that allows for a snap-fit coupling between the housing 110 and the knob 102. In one example, the coupling feature of the housing is an annular ridge or ring 114 that extends partially or completely around the top surface of the housing 110. The knob 102 includes one or more radially inwardly projecting tabs 103 that are configured to snap over the housing's annular ridge 114 to attach the knob 102 to the housing 110. The annular ridge 114 has a diameter that is greater than an inner diameter defined by the one or more radially inwardly projecting tabs 103. Thus, when the knob 102 is axially aligned with the housing 110 and the knob 102 is pushed axially downward about the housing 110, the knob 102 flexes or bends radially outward slightly, which allows the knob 102 to move axially downward relative to the housing 110 and position the radially inwardly projecting tabs 103 below the annular ridge 114 as shown in FIG. 1B. The upper end of the annular ridge 114 and the lower end of the one or more radially inwardly projecting tabs 103 are chamfered or angled to aid in the snap-fit connection between the knob 102 and the housing 110 as described herein. The larger diameter of the annular ridge 114 prevents the knob 102 from separating or falling out of the housing 110. The snap-fit connection between the knob 102 and the housing 110 allows for the connection of the reel-type closure device 100 without the use of bolts, screws, rivets, or other similar mechanical fasteners. Further details of the connection between the knob 102 and the housing 110 are provided in U.S. Patent Application No. 16 / 864,849, entitled "Reel Based Closure System," filed May 1, 2020, the entire disclosure of which is incorporated herein by reference.
[0032]
[0039] The seat component 130 is disposed axially below the spool 120 and releasably couples to the lower end of the housing 110. The seat component 130 typically includes a circular base and a central boss or protrusion 132 that projects axially upward from the circular base into an interior region of the housing 110 when the seat component 130 couples to the lower end of the housing 110. The circular base serves as the bottom surface of the housing 110 when the seat component 130 is attached to the housing 110. The circular base coincides with an opening in the lower end of the housing 110 such that the lower end of the housing 110 is completely covered and closed by the circular base when the seat component 130 couples to the housing 110. The central boss 132 is configured to be inserted through an opening in the spool 120. Additionally, the central boss 132 is axially insertable through a central opening 142 in the pawl disk 140. The central boss 132 and the pawl disk 140 are operatively engaged to enable the reel closure device 100 to transition between an engaged state and a disengaged state.
[0033]
[0040] The spool 120 is rotatably positioned about the seat component 130 by inserting a central boss 132 through a central opening of the spool. The spool 120 can spin or rotate about the central boss 132 with negligible friction. The seat component 130 includes a plurality of radially extending fingers 136 configured to locate in corresponding recesses (not shown) in the lower end of the housing 110. The seat component 130 is rotationally locked with respect to the housing 110 by inserting the radially extending fingers 136 into the recesses, thereby preventing relative rotation of the two components. Additionally, the seat component 130 includes a pair of coupling arms 131 disposed on either side of the seat component 130 and coupling the seat component 130 to the housing 110. The coupling arms 131 extend radially from the seat component 130 and releasably engage the lower end of the housing 110 to releasably couple the seat component 130 to the lower end of the housing 110. Coupling arm 131 includes an upwardly curved lip configured to flex, bend or curve around or over the lower edge of housing 110 to secure seat component 130 to the lower end of housing 110. The lower end of housing 110 includes a pair of small channels into which coupling arm 131 may be positioned such that the underside of seat component 130 is aligned with the underside of housing 110 when seat component 130 is coupled with housing 110.
[0034]
[0041] Each upwardly curved lip includes a radially inward facing protrusion designed to be placed into a small recess on the exterior of the housing 110. By placing each protrusion into a corresponding recess, the seat component 130 is secured to the housing 110. The seat component 130 can be removed from the housing 110 by flexing or bending the upwardly curved lips radially outward so that the protrusions clear the housing recesses. At the same time, an axially downward force can be applied to the seat component 130 to move it axially downward relative to the housing 110.
[0035]
[0042] The pawl disk 140 typically includes a plurality of claw arms 145 attached to a central body or base 146 of the pawl disk 140. In the illustrated embodiment, the pawl disk 140 includes three claw arms 145, although in other embodiments, the pawl disk 140 may include more or fewer claw arms 145 as desired (e.g., a single claw arm, two claw arms, four claw arms, etc.). Each claw arm 145 is fixedly attached to the central body 146 at a proximal end of the respective claw arm 145. Additionally, each claw arm 145 includes one or more teeth 144 disposed at a distal end of the respective claw arm 145. The one or more pawl teeth 144 are configured to engage teeth 118 of the housing 110 in a ratchet-like manner to permit unidirectional rotational movement of the pawl disk 140 and spool 120 relative to the housing 110. One or more pawl teeth 144 engage with the housing teeth 118 to lock the rotational position of the pawl disk 140 and spool 120 relative to the knob 102 and housing 110. The rotational position of the spool 120 relative to the housing 110 is locked by engagement of the spool teeth 126 with the pawl disk teeth 147. Each pawl arm 145 functions as a spring member that biases one or more pawl teeth 144 radially outwardly into engagement with the teeth 118 of the housing 110. Additionally, the pawl arms 145 can flex radially outwardly to contact the teeth 118 of the housing 110, which can reinforce the locked engagement of the pawl disk 140 and the housing 110.
[0036]
[0043] The pawl disk 140 may be snap-coupled to the knob 102. To couple the pawl disk 140 to the knob 102, the knob may include one or more axially extending tabs (not shown) that snap-engage with the central body 146 of the pawl disk 140. For example, a distal end of the axially extending tab of the knob may include a lip shaped and sized to be disposed in a recess or pocket in the central body 146 of the pawl disk. To couple the knob 102 and the pawl disk 140, the pawl disk 140 is axially aligned with the knob 102 and then the pawl disk 140 is pressed axially upward into the interior of the knob 102, which causes the axially extending tab of the knob to flex radially outwardly around the body of the pawl disk 140.
[0037]
[0044] The pawl disk 140 operatively engages the spool 120 to prevent rotation of the spool 120 in the loosening direction. A force or load from tension in the tension member acting on the pawl arm 145 is transferred to one or more pawl teeth 144 which prevent rotation of the spool 120 by engaging with teeth 118 on the housing 110. Additionally, the pawl disk 140 operatively engages the knob 102 such that when the knob 102 is rotated in the tightening direction, the pawl disk 140 also rotates in the tightening direction. Rotating the pawl disk 140 in the tightening direction causes the one or more pawl teeth 144 to flex radially inwardly and progressively out of engagement with the teeth 118. The pawl arm 145 urges the one or more pawl teeth 144 to re-engage the teeth 118 when the rotation of the pawl disk 140 stops or when the pawl disk 140 is rotated in the loosening direction by tension in the tension member. The operative engagement of the pawl disc 140 with the spool 120 transfers a rotational force applied to the knob 102 to the spool 120, causing the spool 120 to rotate in a tightening direction within the housing 110. As the spool 120 rotates in the tightening direction, the tension member is wound onto the spool 120.
[0038]
[0045] In some cases, one or more of the pawl teeth 144 may be oriented to engage with the axially oriented teeth 118. In such embodiments, the one or more of the pawl teeth 144 may be axially displaced or moved in response to rotation of the pawl disk 140 in the clamping direction.
[0039]
[0046] The pawl disc 140 operably engages with the central boss 132 in a manner that allows the pawl disc 140 and / or knob 102 to be supported in one of two positions, an engaged position and a disengaged position. In the engaged position, the pawl disc 140 and / or knob 102 are disposed axially downward relative to the housing 110 and spool 120, allowing the knob 102 to be manipulated to tighten the tensioning member as described herein. FIG. 1B shows the pawl disc 140 and knob 102 in the engaged position. In the disengaged position, the pawl disc 140 and / or knob 102 are disposed axially upward relative to the housing 110 and spool 120, allowing the spool 120 to freely rotate in a loosening direction to loosen the tensioning member.
[0040]
[0047] In the disengaged position, the axially oriented teeth 126 of the spool 120 are spaced apart from and do not contact the axially oriented teeth 147 of the pawl disk 140. Because the axially oriented teeth 126 and 147 of the spool 120 and pawl disk 140 are not engaged, the spool 120 can freely spin or rotate in the loosening direction within the housing 110. In the disengaged position, one or more pawl teeth 144 of the pawl disk 140 can disengage from the housing teeth 118, allowing rotation of the knob 102 and / or pawl disk 140 in the loosening direction. In other embodiments, one or more pawl teeth 144 can remain engaged with the housing teeth 118, preventing rotation of the knob 102 and / or pawl disk 140 in the loosening direction.
[0041]
[0048] In some embodiments, axially upward movement of the pawl disk 140 to the disengaged position can be accomplished by pulling the knob 102 axially upward. As the knob 102 is moved axially upward relative to the housing 110, the radially inwardly projecting tab 103 of the knob 102 can contact the annular ridge 114 of the housing. In other embodiments, the knob 102 can remain axially stationary relative to the housing 110 and the spool 120 while the pawl disk 140 is moved axially upward to the disengaged position. In such embodiments, axially upward movement of the pawl disk 140 can be accomplished by rotating the knob 102 in the loosening direction and / or by using a separate release mechanism or button, such as a lever, button, clamp, etc. For example, to move the pawl disk 140 axially upward, the knob 102 and / or the pawl disk 140 can include a cam surface, an inclined or sloped surface, or another mechanism that moves the pawl disk 140 axially upward when the knob 102 is rotated in the loosening direction.
[0042]
[0049] 1B illustrates the engaged position of the reel closure device 100 in which the pawl disk 140 is axially downward relative to the housing 110 and the spool 120. In the engaged position, the axially oriented teeth 126 of the spool engage and directly contact the axially oriented teeth 147 of the pawl disk. The engagement of the axially oriented teeth 126 and 147 of the spool 120 and the pawl disk 140 operably locks the pawl disk 140 and the spool 120 together such that rotation of the pawl disk 140 in a tightening direction rotates the spool 120 in a tightening direction. Additionally, the spool 120 and the pawl disk 140 are operably locked such that rotation of the spool 120 in a loosening direction rotates the pawl disk 140 in a loosening direction. In the engaged position, the pawls 145 of the pawl disk 140 engage the teeth 118 of the housing, locking the rotational position of the pawl disk 140 and the spool 120 relative to the housing 110 as described herein. The knob 102 is also disposed axially downward relative to the housing 110 and the spool 120 in the engaged position.
[0043]
[0050] The central boss 132 supports and maintains the pawl disk 140 and / or knob 102 in engaged and disengaged positions via annular projections or members 134. The annular members 134 have a diameter larger than the diameter of the central opening 142 of the pawl disk, such that the annular members 134 interfere with the pawl disk 140 around the upper end of the central boss 132 and prevent the pawl disk 140 from moving axially upward and downward. Although the annular members 134 prevent the pawl disk 140 from moving axially upward and downward, the annular members 134 do not prevent the pawl disk 140 from moving axially upward and downward because the central boss 132 is capable of displacing or flexing radially inward. Specifically, the central boss 132 is formed of a pair of fingers or protrusions that extend axially upward from the circular base of the seat component 130. The pair of protrusions flex radially inward toward each other as the pawl disk 140 moves axially upward and downward relative to the annular members 134. Specifically, as pawl disk 140 moves axially upward and downward about annular member 134, engagement of annular member 134 with pawl disk central opening 142 causes the pair of protrusions to deflect inwardly. The pair of protrusions resiliently deflect outwardly to resume an undeflected state after pawl disk 140 moves axially upward and downward about annular member 134. In operation, pawl disk central opening 142 is located above or below annular member 134 which supports and maintains pawl disk 140 and / or knob 102 in either an engaged or disengaged position.
[0044]
[0051] The reel-type closure device 100 may include a reinforcing spring (not shown) for strengthening and reinforcing the pair of protrusions of the seat component 130. To reinforce the pair of protrusions, the reinforcing spring is axially inserted into the axially extending gap between the pair of protrusions of the seat component 130. The reinforcing spring is made of a flexible elastic material, such as spring steel or a non-metallic (e.g., PEAK) material. The reinforcing spring assists in the elastic deflection of the pair of protrusions when the pawl disk 140 moves axially upward and downward around the annular member 134. In addition, the reinforcing spring can strengthen the pair of protrusions and prevent the pair of protrusions from plastic deformation due to long-term use of the reel-type closure device 100.
[0045]
[0052] As shown in FIG. 1C, the seat component 130 includes a spool engagement mechanism 138 configured to engage the lower end of the spool 120 as tension in the tension member decreases. Typically, the spool engagement mechanism 138 and the spool 120 do not engage until the tension in the tension member is at or near a tension threshold, such as a nominal or zero amount of tension. The engagement of the lower end of the spool 120 with the spool engagement mechanism 138 prevents rotation of the spool 120 in the uncoiling direction. In other words, the spool 120 is rotatable in the uncoiling direction until the lower end of the spool 120 contacts and engages the spool engagement mechanism 138. After the spool 120 engages the spool engagement mechanism 138, rotation of the spool 120 in the uncoiling direction is prevented.
[0046]
[0053] In one embodiment, the spool 120 includes teeth (not shown) disposed on a bottom surface of the spool 120 and extending axially from the bottom surface of the spool 120. The spool teeth are configured to engage with circumferentially spaced openings formed in a circular base of the seating component. The openings function as spool engagement features 138 (hereinafter openings 138) such that the spool teeth engage the circumferentially spaced openings to prevent rotation of the spool 120 in the uncoiling direction. In other embodiments, the spool engagement features may be teeth formed on the circular base or may be other frictional components such as rubber-like gaskets or materials, wear materials, adhesive materials, etc.
[0047]
[0054] The spool teeth and apertures 138 do not engage until the tension in the tension member is at or near a tension threshold. Until the spool teeth and apertures 138 engage, the spool 120 can rotate in the tightening and loosening directions as described herein to tension and loosen the tension member. After the spool teeth and apertures 138 engage, further rotation of the spool 120 in the loosening direction is prevented or limited. To allow engagement and disengagement of the spool teeth with the apertures 138, the spool 120 is configured to move axially upward and downward relative to the housing 110.
[0048]
[0055] The engagement of the spool teeth 126 with the pawl disk teeth 147 causes the spool 120 to move axially upward as the pawl disk 140 rotates in a tightening direction. The spool teeth 126 and the pawl disk teeth 147 engage when there is some tension in the tension member because the tension attempts to rotate the spool 120 in a loosening direction relative to the pawl disk 140, which causes the spool teeth 126 to slide axially upward against the pawl disk teeth 147 and engage more deeply with the pawl disk teeth 147 due to the tapered / sloped shape of the teeth 126 and 147.
[0049]
[0056] As tension in the tension member decreases, at some point the tension reaches or exceeds a tension threshold, causing the spool 120 to move axially downward relative to the housing 110, and the spool 120 to contact and engage the seating component teeth 138. The frictional engagement of the spool 120 with the seating component teeth 138 prevents or limits further rotational movement of the spool 120 in the loosening direction. Rotation of the spool 120 in the loosening direction is prevented even when the knob 102 is rotated in the loosening direction. The spool 120 remains in the axially downward position until the pawl disc 140 rotates in the tightening direction, causing the spool 120 to move axially upward as previously described.
[0050]
[0057] 2A-2D show the pawl disk 140 in further detail. FIG. 2A shows the lower end of the pawl disk 140 such that the axially oriented teeth 147 can be seen. The pawl arm 145, one or more pawl teeth 144, the central body 146, and the central opening 142 can also be clearly seen. As further shown in FIGS. 2A and 2B, the distal end of the pawl arm 145 includes a clip or tab 148 (hereinafter, clip 148) that extends axially downward from the underside of the pawl arm 145 in generally the same direction as the teeth 147. The clip 148 is located on the opposite side of the distal end of the pawl arm 145 from the one or more teeth 144. The clip 148 is configured to engage with a small lip or wall 149 (hereinafter, wall 149) formed on the outer edge of the central body 146 of the pawl disk 140. The wall 149 can be seen in FIG. 2D.
[0051]
[0058] As shown in FIG. 2D , clips 148 can be disposed on the inner surface of wall 149 in a recess or channel formed in the outer edge of central body 146. Clips 148 are approximately flush with wall 149 and engage the inner surface of wall 149. Engagement of clips 148 with wall 149 prevents clips 148 from moving radially outward of wall 149, thereby inhibiting radially outward movement of each of pawl arms 145. More specifically, each of pawl arms 145 can move radially outward until its respective clip 148 contacts and engages with a respective wall 149 of central body 146. Once clips 148 and walls 149 engage, further radially outward movement of each of pawl arms 145 is prevented. One function of clips 148 and walls 149 can be to maintain pawl arms 145 in an ideal orientation for assembly of pawl disc 140 with knob 102 and housing 110. Another function of clip 148 and wall 149 may be to facilitate re-engagement of one or more teeth 144 of the pawl disc with teeth 118 of the housing as pawl disc 140 moves or transitions between the disengaged and engaged positions.
[0052]
[0059] The clip 148 and wall 149 are positioned such that when the pawl disk 140 is inserted into the housing 110 and in the engaged position, the one or more teeth 144 of the pawl disk engage with the teeth 118 of the housing. In other words, the clip 148 and wall 149 do not impede, hinder or interfere with the engagement of the one or more teeth 144 of the pawl disk with the teeth 118 of the housing during use of the reel closure device 100. In some embodiments, the clip 148 and wall 149 may not engage after the pawl disk 140 is assembled with the housing 110 and knob 102. In other embodiments, the clip 148 and wall 149 may temporarily engage when the pawl disk 140 moves axially upward to the disengaged position described above. In such an embodiment, clips 148 and walls 149 can facilitate re-engagement of one or more teeth 144 of the pawl disk with the housing teeth 118 by restraining radially outward movement of pawl arms 145 upon disengagement of pawl disk 140 from spool 120. Clips 148 and walls 149 can facilitate re-engagement of one or more teeth 144 of the pawl disk with the housing teeth 118 by maintaining pawl arms 145 in a radial orientation relative to central body 146 and housing 110 that allows one or more teeth 144 of the pawl disk to easily slide or move axially into the housing teeth 118.
[0053]
[0060] In some embodiments, the outer surface or edge of clip 148 can have a chamfered or angled orientation (see FIG. 2D) that aids in moving clip 148 radially inward and over wall 149. In such embodiments, the outer surface of wall 149 can have a corresponding chamfered or angled orientation. Clip 148 is typically formed on a tab or nub that extends radially inward from the body of the distal end of each claw arm 145. By locating clip 148 on the radially extending tab or nub, a desired degree of radially outward movement of the distal ends of claw arms 145 can be achieved.
[0054]
[0061] The clip 148 and wall 149 can enable the use of a stronger pawl arm 145 in the reel closure device 100. The stronger pawl arm 145 can be formed by thickening the wall of the pawl arm 145, using a more elastic material, and / or coupling a reinforcing spring or material to the pawl arm 145. The strengthened pawl arm 145 can enable the reel closure device 100 to handle or accept a larger tensile load of the tension member. The clip 148 and wall 149 can prevent the strengthened pawl arm 145 from moving outward or bouncing in a manner that could damage the reel closure device 100, such as the teeth 118 of the housing, and / or prevent re-engagement of one or more teeth 144 of the pawl disc with the teeth 118 of the housing, as the pawl disc 140 moves or transitions to the engaged position. Additionally, the clip 148 and wall 149 may reduce the overall height of the reeling closure device 100 by allowing one or more internal components or mechanisms to be omitted. Reducing the height of the reeling closure device 100 may allow the reeling closure device to be used in a greater variety of applications and / or may reduce undesirable contact between the reeling closure device 100 and external objects.
[0055]
[0062] 3A-3C show the pawl disk teeth 147 and the spool teeth 126 in further detail. FIG. 3A shows the engagement of the pawl disk teeth 147 with the spool teeth 126. The pawl disk teeth 147 and / or the spool teeth 126 extend axially in opposite directions and are designed to facilitate engagement of the teeth as the pawl disk 140 moves or transitions between the disengaged and engaged positions described herein. Easy engagement of the pawl disk teeth 147 with the spool teeth 126 may be important if the knob 102 contacts an external object in a manner that may cause the knob 102 to pivot or tilt to some degree. If the pawl disk teeth 147 and the spool teeth 126 cannot easily engage, such contact may cause the knob 102 to move upwards unintentionally, releasing tension in the tension member. This undesirable action (i.e., unintentional loosening of the tension member) can be significantly reduced if the pawl disk teeth 147 and the spool teeth 126 can easily re-engage.
[0056]
[0063] To facilitate engagement between the pawl disk tooth 147 and the spool tooth 126, the contour or shape of the engaging or mating surface or face of each pawl disk tooth 147 and / or spool tooth 126 may not be linear or straight. Rather, the engaging surface or face of each pawl disk tooth 147 and / or spool tooth 126 may be configured such that the taper / slope or angle of the engaging surface varies as compared to a vertical reference line. In other words, the angle of the mating surface or face of each pawl disk tooth 147 and / or spool tooth 126 varies along the axial length of the respective tooth. More specifically, a distal portion or tip of the engaging surface / face of each pawl disk tooth 147 and / or spool tooth 126 may be more vertically oriented as compared to a proximal portion of the engaging surface / face of each pawl disk tooth 147 and / or spool tooth 126.
[0057]
[0064] 3B illustrates an exemplary tooth 170 having an engaging surface or face 172 that varies in angle along the length of the tooth 170. The tooth 170 may be representative of each of the pawl disk teeth 147 and / or each of the spool teeth 126. As illustrated, the tooth 170 includes a distal portion or section (also referred to herein as a second angled portion) 174 and a proximal portion or section (also referred to herein as a first angled portion) 176. The angle of the distal portion 174 compared to a vertical reference line is different from the angle of the proximal portion 176 compared to the same vertical reference line. More specifically, the distal portion 174 has a more vertical orientation compared to the proximal portion 176. In some embodiments, the angle of the distal portion 174 may be less than 5 degrees, less than 4 degrees, less than 3 degrees, or less than 2 degrees relative to a vertical reference line, while the angle of the proximal portion 176 may be greater than 3 degrees, greater than 4 degrees, greater than 5 degrees, or greater than 6 degrees relative to a vertical reference line. The angle of the distal portion 174 is typically greater than 1 degree, while the angle of the proximal portion 176 is typically less than 15 degrees or 10 degrees. In the illustrated embodiment, the distal portion 174 has an angle of about 2.5 degrees relative to a vertical reference line, while the proximal portion 176 has an angle of about 6 degrees. It should be noted that the values shown in FIG. 3B are for illustrative purposes only and may be changed depending on a given application or as needed. Thus, the illustrated values are in no way intended to limit the scope of the present specification or claims.
[0058]
[0065] The distal portion 174 is typically less in length than the proximal portion 176, and in some embodiments may extend for less than 40% of the length of the tooth 170, less than 35% of the length of the tooth 170, or less than 30% of the length of the tooth 170. The proximal portion 176 may extend along the remaining portion of the length of the tooth 170, if desired. In one embodiment, only the teeth 147 of the pawl disk 140 may have the altered angular configuration as shown in FIG. 3B. Alternatively, in other embodiments, only the teeth 126 of the spool 120 may have the altered angular configuration as shown in FIG. 3B. In other embodiments, both the teeth 147 of the pawl disk 140 and the teeth 126 of the spool 120 may have the altered angular configuration as shown in FIG. 3B.
[0059]
[0066] The latter embodiment, in which both teeth 126 and 147 have a changed angular configuration, may be preferred because the more vertically oriented tip or distal end of each tooth significantly improves re-engagement or re-mating of teeth 126 and 147. The more vertically oriented surface of each tooth 126 and 147 further reduces the force required to move pawl disk 140 axially upward out of engagement with spool 120 and reduces wear on the faces and tips of each tooth 126 and 147. These advantages may allow the size of teeth 126 and 147 to be reduced, thereby reducing the overall size or height of reel closure device 100. The larger angle of the proximal portion of each tooth 126 and 147 facilitates maintaining engagement of pawl disk 140 with spool 120, particularly as tension in the tension member increases. This improved engagement between the pawl disc 140 and the spool 120 minimizes accidental disengagement of the two components which can cause undesirable loosening of the tension member.
[0060]
[0067] 3C illustrates teeth 126 of spool 120 having the varied angle configuration described above. Specifically, each tooth 126 includes a proximal portion, or first angled portion 127a, and a distal portion, or second angled portion 127b, with distal portion 127b having a more vertical orientation than proximal portion 127a compared to a vertical reference line or plane. In some instances, proximal portion 127a may directly abut or contact distal portion 127b, while in other instances, a transition or zone may be formed between proximal portion 127a and distal portion 127b, as illustrated by the shaded area between proximal portion 127a and distal portion 127b in FIG. 3C.
[0061]
[0068] FIG. 4 shows a bottom perspective view of the housing 110. The bottom perspective view shows the interior of the lower portion of the housing 110 located axially below the inner annular ridge 116. As shown, the lower portion of the housing 110 includes a plurality of channels, recesses, or depressions 113 (hereinafter channels 113) formed in the inner surface of the housing wall and extending axially along the housing wall. In some embodiments, the channels 113 may extend from the inner annular ridge 116 to a lower edge or lower surface of the housing 110, which may be open. In other embodiments, the channels 113 may extend along only a portion of the housing 110 and not to the lower edge / lower surface and / or the inner annular ridge 116. In some embodiments, the housing 110 may include between 4 and 20 channels 113, more typically between 5 and 12 channels 113, and most typically between 6 and 10 channels 113. In certain embodiments, the housing 110 may include 8 or 9 channels 113.
[0062]
[0069] The channels 113 define inner extending surfaces 115 located between adjacent channels 113. The inner extending surfaces 115 extend axially along the housing wall and may extend completely or partially from the inner annular ridge 116 to a lower edge or underside of the housing 110, which may be open. By forming the channels 113 on the inner surface of the housing wall, frictional contact between the tension member and the housing 110 is reduced. Specifically, using the channels 113, the tension member (not shown) contacts one or more surfaces 115 of the housing 110 as the spool 120 rotates in a tightening or loosening direction inside the housing. The upper and lower flanges of the spool 120 may also briefly contact one or more surfaces 115 of the housing wall as the spool 120 rotates inside the housing. Because the channel 113 is recessed into the inner wall of the housing 110, the flange of the tension member or spool does not contact material within the channel 113, but instead only contacts material on one or more surfaces 115 of the housing 110. In this manner, contact between the flange of the tension member or spool and the inner wall of the housing 110 is reduced, reducing friction or drag on the flange of the tension member or spool. The reduction in friction or drag increases the tension on the tension member as it is wound around the spool 120, since more of the input energy is transferred directly to the tension member. Similarly, the reduction in friction or drag results in easier unwinding of the tension member from the spool 120 when the tension member is being unwound.
[0063]
[0070] 5 shows a top or bottom cross-sectional view of the spool 120. The spool 120 includes a central cylindrical body 125 about which the tension member is wound and unwound when tightening and loosening the tension member. Additionally, the spool 120 includes a channel or recess 121 that extends or is defined within the spool's central cylindrical body 125. The channel or recess 121 (hereinafter, channel 121) typically extends through the central cylindrical body 125 from one side of the central cylindrical body 125 to the opposite side of the central cylindrical body 125. The channel 121 is disposed on one side of a central opening of the spool 120. Channel 121 is used in attaching the tension member to the spool, as further described in U.S. patent application Ser. No. 62 / 101,283, filed Jan. 8, 2015, entitled "Closure System Components for Enabling Easy Attachment of Lace," the entire disclosure of which is incorporated herein by reference.
[0064]
[0071] The spool 120 generally includes a single channel 121, although in some embodiments, the spool 120 may include additional channels 121 disposed on opposite sides of the central opening. As further shown in FIG. 5, the cylindrical body 125 of the spool 120 is not perfectly cylindrical. Rather, the cylindrical body 125 has a more oval profile when viewed in cross section from a top or bottom view as in FIG. 5. Due to the more oval profile of the cylindrical body 125, the cylindrical body 125 of the spool 120 has an asymmetric shape. This shape reduces wear and / or pressure points on the tension members, thereby reducing failure of the tension members after extended use.

[0073] The embodiments of Figures 6A-12G relate to orthotic braces that can be placed around a limb to support the limb, promote healing, and / or provide support and reinforcement to the limb. In certain embodiments, the brace is a knee brace that can be placed around the leg and configured to support the patella of the knee. The embodiments described herein use a single tightening mechanism to hold the patella in a centered position. For ease of description of the embodiments herein, orthotic braces are generally referred to as knee braces.
[0067]
[0074] In addition to the reel-based closure devices described herein, other tightening mechanisms that may be used include pull cord systems, motorized systems or devices, traditional laces, or any other system capable of pulling a lace or cord. Exemplary embodiments of such devices are further described in U.S. patent application Ser. No. 13 / 098,276, entitled "Reel Based Lacing System," filed Apr. 29, 2011, U.S. patent application Ser. No. 14 / 328,521, entitled "Closure Devices Including Incremental Release Mechanisms and Methods Therefor," filed Jul. 10, 2014, and U.S. patent application Ser. No. 12 / 623,362, entitled "Reel Based Lacing System," filed Nov. 20, 2009, the entire disclosures of which are incorporated herein by reference.
[0068]
[0075] In some embodiments, the knee brace includes a petal configuration that can be positioned around the patella. The petal configuration can include a plurality of wedge-shaped petals that can be tensioned to support the patella and knee joint by pulling the petals into contact with the knee around the patella. FIGS. 6A-6C show a first embodiment of a knee brace 200 that includes a petal configuration. The knee brace 200 has a brace body 202 and a support member 210 that is attached to the brace body 202 by sewing, gluing, insert molding, etc. The support member 210, when attached to the brace body 202, forms or defines an opening 204 that at least partially surrounds the patella. In the illustrated embodiment, the support member 210 is a single annular member that completely surrounds the patella with no breaks or discontinuities in the support member 210. In other embodiments, the support member may be formed from two or more pieces that are positioned on the brace body 202 such that the support member 210 surrounds the patella.
[0069]
[0076] The support member 210 includes a plurality of petals or fingers 212 (hereinafter, petals 212), each of which projects radially inward toward the center of the knee or patella. The petals 212 may be wedge-shaped components and may have padding on the underside of the petals 212 that contact the knee to provide comfort and cushioning to the knee. Small slits or openings may be formed between adjacent petals 212 to allow or assist the plurality of petals 212 to contract inwardly around the knee and patella. The petals 212 may have foam wedge padding on the interior of the petals, which may provide a comfortable focus of pressure around the patella.
[0070]
[0077] A guide member 214 is operably coupled to each of the petals 212. An example of a guide member 214 is shown in FIG. 6B. In the illustrated embodiment, the guide member 214 is disposed on the inside of each petal 212. In other embodiments, the guide member 214 may be disposed on the outside of each petal, or the guide member may be integrated into the petal 212. For example, one or more of the petals 212 may be looped inward to form a channel into which the tension member is inserted or disposed. Each petal 212 may have the same guide member configuration, or the guide members may be disposed differently on each petal 212. For example, one or more petals 212 may have an inwardly directed guide member 214, one or more petals 212 may have one or more outwardly directed guide members 214, and / or one or more petals may have an integrated guide member 214.
[0071]
[0078] The reel closure device 220 is also attached to the brace body 202 adjacent to the support member 210. In some embodiments, the reel closure device 220 is positioned on the brace body 202 such that the reel closure device 220 is located vertically above the support member 210, although the reel closure device 220 may be positioned elsewhere as desired. The reel closure device 220 may be positioned at the horizontal center of the support member 210 or offset from the horizontal center as shown in FIGS. 6A-6C. In some embodiments, the reel closure device 220 may be offset from the horizontal center such that the reel closure device 220 is closer to the inner portion of the leg, which may protect the reel closure device 220 from contact with external objects that may cause undesired damage to the reel closure device 220 and / or undesired opening of the reel closure device 220 and loosening of the tension member.
[0072]
[0079] A tensioning member or string is operably coupled to the reel closure device 220 such that movement of the reel closure device 220 (e.g., rotation of a knob) tensions the tensioning member. As described herein, a tensioning member (not shown) is operably coupled to each guide member 214, such as by inserting the tensioning member through an opening in each guide member, such that pulling the tensioning member causes the petal 212 to contract inwardly around or around the patella. The string path of the tensioning member is shown in FIG. 6C by dashed lines 216. The string path of the tensioning member forms or defines a loop or circle around the patella. Pulling the tensioning member contracts or decreases the diameter of the loop or circle, pulling the petal 212 inwardly toward the center of the knee. This action causes the petal to exert inward and downward pressure on the leg and knee around the patella to support and reinforce the patella. The petals 212 may be positioned to contact the patella and / or the tissue immediately surrounding the patella.
[0073]
[0080] As shown in FIG 6C, the lacing path of the tension member may be positioned such that the tension member crosses itself near the reel closure device 220. In other embodiments, the lacing path may not cross itself along the entire length of the lacing path. Crossing the lacing path as shown in FIG 6C may introduce friction into the lacing system, thereby maintaining the fit and retention of the support member 210 around the patella by inhibiting slippage of the tension member in the guide member 214.
[0074]
[0081] 7A-7C show a second embodiment of a knee brace 240 including a petal configuration. The knee brace 240 has a brace body 242 and a support member 250 attached to the brace body 242 by stitching, gluing, insert molding, etc. In the illustrated embodiment, the support member 250 is a single U-shaped member that partially encircles the patella. The U-shaped support member 250 may be formed from a single continuous member or may be formed from multiple pieces that are placed on and attached to the brace body 242 to form the U-shaped support member 250. In other examples, the support member 250 can completely encircle the patella without any breaks or discontinuities in the support member 250.
[0075]
[0082] The support member 250 partially or completely surrounds the support pad 244 that is placed on the patella. In a particular embodiment, the support pad 244 is a gel donut-shaped pad that surrounds the patella and the lateral and medial sides of the knee. The support member 250 partially or completely surrounds the support pad 244. The support member 250 includes a plurality or set of overlapping petals or fingers (hereinafter, petals) that provide a canopy effect over the support pad 244. The support member 250 may be particularly useful for knee braces that include a donut-shaped support pad 244. Specifically, the support member 250 includes a first set of petals 254 that are disposed at the base of the support pad 244 and a second set of petals 252 that are disposed on the support pad 244. Each of the first set 254 and the second set 252 of petals is configured to allow the tension member 222 to be guided or guided along a path by the respective petal. The first set of petals 254 and the second set of petals 252 may include guides disposed on inner portions of the petals, on outer portions of the petals, and / or integral with each petal as described above. The tension members 222 may be inserted through the guides of each of the petals such that the petals can guide or guide the tension members 222 along the string path.
[0076]
[0083] Each petal of the first set 254 and the second set 252 projects radially inward toward the center of the patella or knee. The petals of the second set 252 project radially inward further than the petals of the first set 254. The first set 254 and the second set 252 of petals exert an inward and downward pressure on the support pad 244, which exerts an inward and downward pressure on the patella and knee. The petals of the first set 254 and the second set 252 may be wedge-shaped components and may have padding under them, if desired. Small slits or openings may be formed between adjacent petals of the first set 254 and the second set 252, which may allow or assist the petals to contract inwardly around the support pad 244.
[0077]
[0084] The reel closure device 220 is also attached to the appliance body 242 adjacent to the support member 250. In some embodiments, the reel closure device 220 is positioned on the appliance body 242 such that the reel closure device 220 is positioned vertically above the support member 250 and between the ends of the U-shaped support member 250. The reel closure device 220 may be positioned elsewhere as desired. The reel closure device 220 may be horizontally centered on the support member 250 as shown.
[0078]
[0085] A tension member 222 is operably coupled to the reel-type closure device 220 such that the tension member is pulled by the action of the reel-type closure device 220 (e.g., rotation of a knob). The tension member 222 is operably coupled to each of the petals such that a continuous path is formed by the tension member 222. Specifically, starting from the reel-type closure device 220, following the string path in a counterclockwise direction, the tension member is led from the reel-type closure device 220 through each of the guides of the second set of petals 252. The tension member 222 is then led from the upper right petal of the second set 252, over the top 258 of the support pad 244, and through each of the guides of the first set of petals 254. The tension member 222 is led from the upper right petal of the first set 254 to the reel-type closure device 220. In this manner, the tension member 222 completely surrounds the support pad 244. Pulling the tension member 222 causes the first set of petals 254 to contract radially inward, creating a generally inward pressure on the support pad 244. Pulling the tension member 222 also causes the second set of petals 252 to contract radially inward, creating an inward pressure and a greater downward pressure on the support pad 244. The support member 250 supports and reinforces the patella. Additionally, the support member 250 allows for dual level adjustment with a single reel closure device 220.
[0079]
[0086] 8A-8D show a third embodiment of a knee brace 300 including a petal configuration. The knee brace 300 includes a brace body 302 and a support member 310 that is attached to the brace body 302 by sewing, gluing, insert molding, etc. In the illustrated embodiment, the support member 310 completely surrounds or encircles the patella, although in other embodiments the support member 310 may only partially surround the patella. The support member 310 may be formed from a single continuous member or may be formed from multiple pieces that are placed on and attached to the brace body 302.
[0080]
[0087] As with the previous embodiment, the support member 310 may partially or completely surround a support pad (not shown) that is placed over the kneecap. The support pad may be a gel donut-like pad or any other padded member that surrounds the kneecap and the lateral and medial sides of the knee. In some cases, the knee brace 300 may not include a support pad, and the support member 310 may more directly engage the patella or other portions of the leg or knee to provide comfort and cushioning to the knee.
[0081]
[0088] The support member 310 includes a plurality of petals or fingers 312 (hereinafter, petals) that provide a canopy effect over the support pad or patella. An opening is formed between adjacent petals 312 that allows or assists the petals 312 to retract inwardly around the support pad or patella. The petals 312 may include internal padding that can comfortably focus pressure around the patella. Each petal 312 is configured to allow the tension member 222 to be guided or guided along a path by the respective petal. The petals 312 include guides disposed on an inner portion of the petal, disposed on an outer portion of the petal, and / or integrated into the respective petal as described above. The tension member 222 is inserted through the respective guide of the petal 312 to allow the tension member 222 to be guided or guided along the lacing path by the petal. When the tension member 222 is tensioned by manipulating the reel closure device 220 (eg, by turning the knob), the petals 312 retract inwardly around the patella or support pad, as previously described.
[0082]
[0089] The reel closure device 220 may be located at the uppermost position or location of the leash path. In such a case, the tension member 222 is immediately led from the reel closure device 220 to adjacent petals 312 located on either side of the reel closure device 220. The tension member 222 may or may not cross itself near the reel closure device 220 depending on whether it is desired to introduce an amount of friction into the system. If the tension member 222 does not cross itself, the petals 312 can more easily accommodate knee movements such as those due to bending and flexing of the leg.
[0083]
[0090] In some embodiments, one or more panels or straps 320 (hereafter panels 320) can be attached to the support member 310. The one or more panels 320 are typically attached to one or more sides of the support member 310 and are operable to introduce a desired force or pressure to the knee or patella. For example, in the illustrated embodiment, the knee brace 300 includes two panels 320 attached to either side of the support member 310. More specifically, a leading edge of each panel 320 is attached to the support member 310 by sewing, gluing, molding, etc. The body of each panel 320 is movable about the knee brace 300. For example, the leading edge of each panel 320 may be the only permanent attachment of the panel 320 to the knee brace 300 and the support member 310. This connection allows the panel 320 to pivot about the leading edge attachment and to be pulled laterally or rearwardly about the knee brace 300.
[0084]
[0091] Additionally, each panel 320 includes a fastener 322 that allows the panel 320 to be attached to the body of the knee brace 300. In the illustrated embodiment, the panel 320 includes a hook-and-loop fastener 322 configured to fasten to a hook-and-loop fastener 324 disposed on the body of the knee brace 300. In other embodiments, the panel 320 may include other fasteners, such as magnetic fasteners, buckles, snaps, clamps, and the like. The panel 320 is designed to be pulled backwards relative to the knee brace 300 and attached to the body of the knee brace. This action exerts a lateral (i.e., circumferential direction around the knee / leg) force on the support member 310, which pulls the support member 310 into greater contact with the patella, thereby increasing support for the patella and knee. When the knee brace 300 includes a pair of panels 320 as shown in FIG. 8C and FIG. 8D, the pair of panels 320 can exert equal, opposing forces or pressures on the patella. The use of panels 320 as shown in Figures 8C and 8D can increase lateral support to the patella as compared to the support provided by only the use of support member 310. The force or pressure applied by the pair of panels 320 shown in Figures 8C and 8D can be directed behind the leg and / or downward around the knee.
[0085]
[0092] It should be noted that while a pair of panels 320 are shown in Figures 8C and 8D as being used, in other examples, the knee brace 300 may include a single panel 320 and / or the panels may be located elsewhere as desired. For example, the knee brace 300 may include a panel that is positioned below the support member 310 and configured to apply a downward force to the support member 310 directed toward the foot. Similarly, the knee brace 300 may include a panel 320 that is positioned above the support member 310 and applies an upward force to the support member 310 directed toward the thigh. In some embodiments, the knee brace may include multiple panels 320 that surround the support member 310 and can be independently operable to apply a force to the support member 310 as desired. In this manner, the force or pressure exerted on the patella and knee may be altered and / or customized as desired.
[0086]
[0093] 9 illustrates a fourth embodiment of a knee brace 400 including a patella or knee support configuration. The knee brace 400 includes a brace body 402 and a number of straps 410 coupled to the brace body 402 and arranged to function similarly to the support members described above. Each strap 410 has a proximal end attached to the brace body 402 by sewing, gluing, insert molding, etc. The straps 410 are arranged such that the distal end of the strap is directed toward the patella or knee. Additionally, the straps 410 are arranged such that the distal end of each strap 410 surrounds the patella in a circular or elliptical manner. Each of the straps 410 may be oriented at an angle relative to an adjacent strap 410.
[0087]
[0094] A lacing guide is formed or attached to the distal end of each strap. The lacing guide is configured to guide or direct the tension member 222 around a path around the patella as described above. For example, the distal end of each strap 410 may be folded back to form a loop into which the tension member 222 is inserted. In other embodiments, a separate guide, such as a plastic guide component, may be attached to the distal end of one or more straps 410. The advantage of forming a loop at the distal end of the strap 410 is that the strap 410 is flexible and can conform to the shape of the leg and knee, thus eliminating or reducing pressure points.
[0088]
[0095] A tension member 222 is inserted through each strap and leads from a reel-type closure device 220 that may be located at the top of the lacing path or elsewhere around the knee brace 300 as desired. Pulling the tension member 222 by operating the reel-type closure device 220 pulls each of the straps 410 inward against the knee, creating an inward and slightly downward pressure on the patella and knee. This pressure may support the patella and / or provide additional cushioning and comfort to the knee. Use of the straps 410 may create a "wrap" force around the knee that begins at the proximal end of each strap 410 and wraps around the knee toward the patella. In some embodiments, one or more or each strap 410 may include a pad or cushion on the inner surface that provides additional comfort and / or pressure at a desired location around the leg and knee. The number and location of the straps 410 may be varied to provide a desired force or pressure on the leg and knee. Similarly, the length and width of the straps 410 can be varied to create a desired force or pressure on the legs and knees.
[0089]
[0096] 10A-10C show a fifth embodiment of a knee brace 500 including a support member 510 for supporting and / or cushioning the patella and knee. The knee brace 500 includes a brace body 502 and a reel-type closure device 220. The reel-type closure device 220 is attached to the brace body 502 and disposed on an outer surface of the brace body 502. The reel-type closure device 220 may be disposed at the top point of the lacing path as described above, or may be disposed elsewhere on the brace body 502 and knee brace 500 as desired.
[0090]
[0097] 10B and 10C, a view of the inside of the knee brace 500 is shown by inverting the knee brace, for example, inside out. In contrast to the previous embodiment, the support member 510 is disposed inside the knee brace 500. Thus, the support member 510 and the reel-type closure device 220 are disposed on opposite surfaces of the knee brace 500. The support member 510 is disposed inside the knee brace 500 and partially or completely surrounds the patella. The reel-type closure device 220 is operatively coupled to a tension member 222 that can be tensioned to support and / or cushion the patella and knee by contracting the support member 510 around the patella. The tension member 222 is guided inside the support member 510 so as not to contact the wearer's skin and not to be visible from the outside of the knee brace 500. The tension member may be coupled to one or more cushioning members or pads 512 (hereinafter pads 512).
[0091]
[0098] In some embodiments, the pad 512 includes or functions as a guide to guide or direct the tension member 222 around the patella. In other embodiments, the tension member 222 can be attached to one or more pieces of the pad 512 such that pulling on the tension member 222 causes the pad 512 to move or slide within the support member 510 and contract around the patella. In certain embodiments, the pad 512 is wedge-shaped and includes two pieces of pad configured to slide over one another. As the wedges slide over one another, the volume of material within the support member 510 increases, thus increasing the downward force on the patella or knee. For example, the pad 512 may include two U-shaped wedges that overlap with one U-shaped wedge piece facing up and one U-shaped wedge piece facing down. As the opposing U-shaped wedge pieces slide over one another, downward pressure is created around the patella and knee.
[0092]
[0099] When the tension member 222 is pulled by the operation of the reel-type closure device 220, the support member 510 contracts inwardly, exerting inward and slightly downward pressure on the patella and knee to support and / or cushion the patella and knee. The knee brace 500 of FIGS. 10A-10C may allow the support member 510 to be placed directly on the knee, without the need to press the outer material layer of the knee brace 500 downward and inward, allowing for more direct force to be applied to the patella. Additionally, the knee brace 500 of FIGS. 10A-10C may provide a more desirable visual appeal, since the support member 510 and tension member 222 are hidden from view.
[0093]
[0100] Further patella support concepts are shown in the appendix of the drawings. Each of these systems includes a reel-type closure device and tensioning members that can operate to provide support and / or cushioning to the patella and knee. The location and orientation of the various components, as well as the operation and function of the support member or patella support component, will be readily apparent upon visual inspection of the various embodiments in the appendix. Applicant reserves the right to describe features of the various embodiments in future applications, and it is recognized that the description of features that are readily apparent upon visual inspection of the embodiments does not constitute new matter.
[0094]
[0101] 11A-11D, an embodiment of an ankle brace 600 that can be worn around the ankle to support and strengthen the ankle is shown. The ankle brace 600 includes a brace body 602 having a lateral side 610 and a medial side 620 designed to be positioned on either side of the wearer's foot. The lateral side 610 and the medial side 620 are typically attached along a rear portion that is positioned behind the wearer's leg and along a lower portion that is positioned below the wearer's foot. The lateral side 610 and the medial side 620 are typically not attached along a front portion, thus allowing the ankle brace 600 to be opened and fitted around the wearer's foot.
[0095]
[0102] Additionally, the ankle brace 600 includes a primary closure system and a secondary closure system designed to close the ankle brace 600 around the foot and secure the ankle brace to the foot in a comfortable, supportive manner. The primary closure system comprises or consists of a reeled closure device 220, a tensioning member 222, and a number of guides that direct or guide the tensioning member 222 around a path along the ankle brace 600. These components function in the manner described herein. The reeled closure device 220 may be located near the top or cuff of the ankle brace as shown in Figures 11A-11D, or may be located elsewhere around the ankle brace 600 as desired.
[0096]
[0103] The secondary closure system consists of one or more straps 604 that may be wrapped and secured by the wearer around the ankle brace 600. While the primary closure system may provide a first type of closure, such as a general closure and fit of the ankle brace 600 around the wearer's lower leg, the secondary closure system provides a second type of closure, such as a secure fit of the ankle brace 600 around the foot.
[0097]
[0104] FIG. 11B shows the strap 604 separated from the brace body 602 so that the lateral side 610 and medial side 620 of the brace body 602 are readily apparent. The lateral side 610 includes a stabilizer (shown in outline) that stabilizes the lateral side 610, more specifically the lateral edge, around the wearer's foot. The stabilizer reduces buckling of the lateral side 610 when the ankle brace 600 is closed and tightened around the foot and when the ankle brace 600 is worn. The stabilizer may include multiple layers of material, such as one or more layers of looped fabric and a woven polymer (TPU) backing. As shown in FIG. 11C, the medial side 620 also includes a stabilizer (shown in outline) that stabilizes the medial side 620 of the brace body 602 around the wearer's foot. In certain embodiments, the medial side 620 includes a pair of stabilizers, as shown in FIG. 11C. The medial 620 stabilizers are separate or independent panels or members that are movable relative to one another to some degree. The use of separate, movable stabilizer members allows for a better fit and harmony to be achieved around the midfoot. The medial 620 stabilizer may include multiple layers of material, such as one or more layers of looped fabric and a woven polymer (TPU) backing.
[0098]
[0105] The lateral 610 and / or medial 620 stabilizers can be shaped to conform to the shape and size of the wearer's foot. The stabilizers provide a generally static support system while providing some degree of conformance or resilience. As shown in FIG. 11D, one or more guides are permanently or removably coupled to the lateral 610 and / or medial 620 stabilizers. The lateral 610 includes an upper guide 612 and a pair of lower guides 614 and 616. The upper guide 612 guides or directs the tension member 222 between the medial upper guide 626 and the middle guide 627, while the lower guides 614 and 616 function in cooperation to guide or direct the tension member 222 between the medial middle guide 627 and the lower guide 628. The use of lower guides 614 and 616 working in concert relieves tension in the tension member 222 when the tension member is directed more than 180 degrees and reduces buckling of the bottom of the lateral side 610 of the brace body 602. Upper guide 626 and middle guide 627 are attached to the upper stabilizer on the medial side 620, while lower guide 628 is attached to the lower stabilizer on the medial side 620.
[0099]
[0106] Pulling the tension member 222 pulls the lateral side 610 and the medial side 620 toward each other, constricting the ankle brace 600 around the wearer's ankle. The straps 604 can then be wrapped around the brace body 602 and secured together according to the wearer's preference. The straps 604 can be secured via hook and loop fasteners, clamps, buckles, snaps, magnetic fasteners, or using any other mechanical fastening means.
[0100]
[0107] 12A-12G show another embodiment of an ankle brace 700 that can fit around the ankle to support and strengthen the ankle. The ankle brace 700 includes a brace body 702 having a lateral side and a medial side designed to be positioned on either side of the wearer's foot. The lateral side and medial side are typically attached along a rear portion that is positioned behind the wearer's leg and along a lower portion that is positioned below the wearer's foot. The lateral side and medial side are typically not attached along a front portion, thus allowing the ankle brace 700 to be opened up and fitted around the wearer's foot.
[0101]
[0108] The ankle brace 700 includes a primary closure system (e.g., a reeled closure device 220, a tensioning member 222, and a guide) and a secondary closure system (e.g., one or more straps) designed to close the ankle brace 700 around the foot and secure the ankle brace to the foot in a comfortable, supportive manner. The reeled closure device 220 may be located near the top or cuff of the ankle brace, or may be located elsewhere around the ankle brace 700 as desired. In certain embodiments, the reeled closure device 220 is located near the lateral midpoint or near the midpoint of the lacing path of the tensioning member 222, as shown in FIG. 12B. Positioning the reeled closure device 220 in this manner can provide a more uniform fit and reduce undesirable deflection or movement of the tensioning member 222 around the lacing path. Positioning the reeled closure device 220 at the midpoint of the lacing path is made possible by using a dial strap 720 as described herein below. The primary closure system can provide a first type of closure, such as overall closure and fit of the ankle brace 700 around the wearer's lower leg, while the secondary closure system provides a second type of closure, such as a secure fit of the ankle brace 700 around the foot.
[0102]
[0109] 12B shows the pair of straps 720 and 730 separated from the brace body 702 so that the exterior and interior of the brace body 702 are more readily apparent. The exterior includes a stabilizer (shown in outline) that stabilizes the exterior, or more specifically the exterior edge, around the wearer's foot. The stabilizer reduces buckling of the exterior when the ankle brace 700 is closed and tightened around the foot and when the ankle brace 700 is worn. The stabilizer may include multiple layers of material, such as one or more layers of looped fabric and a woven polymer (TPU) backing.
[0103]
[0110] As shown in FIG. 12C, the medial side also includes a stabilizer (shown in outline) that stabilizes the medial side of the orthotic body 702 around the wearer's foot. In certain embodiments, the medial side includes a pair of stabilizers, as shown in FIG. 12C. The medial stabilizers are separate or independent panels or members that are movable relative to one another to some extent. The use of separate movable stabilizer members allows for a better fit and harmony to be achieved around the midfoot. The medial stabilizer may include multiple layers of material, such as one or more layers of looped fabric and a woven polymer (TPU) backing.
[0104]
[0111] The lateral and / or medial stabilizers can be shaped to conform to the shape and size of the wearer's foot. The stabilizers provide a generally static support system while providing some degree of conformance or resilience. As shown in FIG. 12B and FIG. 12C, one or more guides are permanently or removably coupled to the lateral and / or medial stabilizers. In the illustrated embodiment, the lateral includes three guides 706, one located above the reel-type closure device 220 and two located below the reel-type closure device 220. The medial includes four guides 710, three upper guides 710 attached to the upper stabilizer and the lowest guide 710 attached to the lower stabilizer. The arrangement of the three lateral guides 706 and four medial guides 710 allows for a uniform and even fit to be achieved.
[0105]
[0112] In some embodiments, the upper stabilizer may be split into an upper portion 712 and a lower portion 714, which may be slightly separated by a groove or channel between the two portions. Splitting the upper guide into an upper portion 712 and a lower portion 714 allows the upper stabilizer to be adjusted to better fit the shape of the wearer's leg. The lower stabilizer 716 is separate from the upper stabilizer and can be moved, shifted, and adjusted independently of the upper stabilizer, allowing for a better fit and fit, especially around the midfoot. The material of the lower stabilizer 716 may be tapered on the underside to reduce pressure on the edges of the panel.
[0106]
[0113] 12D and 12E, in some embodiments, the upper outer guide 706 may be a releasable guide, meaning that the tension member 222 may be removed from the guide 706. The guide 706 includes an open rear end that allows the tension member 222 to be quickly inserted and removed from a channel defined in the guide 706. Moving the tension member 222 in and out of the channel of the guide 706 allows for quick adjustment of the tension of the ankle brace 700 and facilitates removal and placement of the ankle brace 700 around the wearer's foot. FIG. 12D shows the tension member 222 positioned within the channel of the guide 706, while FIG. 12E shows the tension member 222 removed from the guide 706.
[0107]
[0114] The dial strap 720 is shown in FIG. 12F. The dial strap 720 includes a central section or body 722 having a window or elongated channel 724 (hereinafter, elongated channel 724) designed to accommodate the reel-type closure device 220. Specifically, the elongated channel 724 has a width slightly wider than the width of the reel-type closure device 220, thereby allowing the dial strap 720 to be placed over the reel-type closure device 220 with the reel-type closure device 220 positioned within the elongated channel 724 of the dial strap 720. Additionally, the elongated channel 724 has a longitudinal length that allows the dial strap 720 to slide or move longitudinally when the reel-type closure device 220 is positioned within the elongated channel 724. In this manner, the position of the reel-type closure device 220 on the ankle brace 700 does not interfere with the placement and / or closure of the dial strap 720 around the ankle brace 700. Additionally, the use of the elongated channel 724 in the dial strap 720 allows for the reel closure device 220 to be positioned at or near the midpoint of the lacing path without adversely affecting the placement and closure of the dial strap 720 around the ankle brace 700. In some embodiments, the body 722 of the dial strap 720 is reinforced relative to the remainder of the dial strap 720, thereby reducing or preventing breakage of the dial strap 720 at or near the elongated channel 724. A reinforcing material or layer may be bonded to the dial strap 720 at or near the elongated channel 724 to reinforce the body 722.
[0108]
[0115] FIG. 12G illustrates the dial strap 720 wrapped around the ankle brace 700 and mounted or placed over the reel closure device 220, which is located in an elongated channel 724 in the dial strap body 722. FIG. 12G further illustrates that a secondary strap 730 is wrapped around the ankle brace 700 and over the dial strap 720. A distal end 732 of the secondary strap 730 is attached near the top edge or top of the outer side of the ankle brace 700. The distal end 732 of the secondary strap 730 may be placed over the distal end of the dial strap 720 to securely hold the dial strap 720 to the brace body 702 or to reinforce the attachment of the dial strap 720 to the brace body 702. In some cases, the wrapping of the dial strap 720 and secondary strap 730 may be reversed, such that the secondary strap 730 is wrapped around the ankle brace 700 first, and then the dial strap 720 is wrapped over the secondary strap 730.
[0109]
[0116] The secondary strap 730 and / or the dial strap 720 may be formed of an elastic or semi-elastic material, or one or both of the straps may be formed of a non-elastic material. In some embodiments, the dial strap 720 and the secondary strap 730 are opposing ends or portions of the same strap. The dial strap 720 and / or the secondary strap 730 may be coupled to the ankle brace 700 so as to rest on or below the wearer's foot.
[0110]
[0117] Pulling on tension member 222 pulls the lateral and medial sides toward each other, constricting ankle brace 700 around the wearer's ankle. Dial strap 720 and secondary strap 730 can then be wrapped around brace body 702 and secured together according to the wearer's preference. Straps 720 and 730 can be secured via hook-and-loop fasteners, clamps, buckles, snaps, magnetic fasteners, or using any other mechanical fastening means.
