Sports racquets are using a variety of sports including racquetball, pickle ball, tennis, padel, platform tennis, squash, badminton, table tennis and the like. Some sports racquets are equipped with wrist straps that extend about the wrist associated with the hand gripping the racquet. The wrist strap assists in maintaining control over the racquet should a player lose his or her grip of the racquet.
Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements. The figures are not necessarily to scale, and the size of some parts may be exaggerated to more clearly illustrate the example shown. Moreover, the drawings provide examples and/or implementations consistent with the description; however, the description is not limited to the examples and/or implementations provided in the drawings.
Disclosed are example sports racquet and removable wrist strap systems, sports racquets, and removable wrist strap assemblies that facilitate quick and easy connection and disconnection of a wrist strap from a sports racquet. By facilitating quick and easy connection and disconnection of the wrist strap from a sports racquet, the systems, racquets, and wrist strap assemblies permit a player to disconnect the wrist strap when the player no longer wishes to use the wrist strap. The disclosed systems, racquets, and wrist strap assemblies further permit the player to replace or exchange the wrist strap in circumstances such as when the wrist strap has become sweaty during play, such as when the wrist strap has been damaged and needs replacement, or such as when the player desires a different wrist strap having a different size or formed from a different material.
The example systems, racquets and wrist strap assemblies utilize a collar and an insert to releasably connect the wrist strap to the sports racquet. A flexible tether extending from an end a handle of the racquet secures one of the collar and the insert to the racquet. The other of the collar and the insert is connected to the wrist strap. The collar has an interior side opening and a side slot extending from the side opening. The insert is insertable into the interior through the side opening while portions of the wrist strap or flexible tether are insertable into the interior through the side slot. In a reverse fashion, the insert is removable from the interior through the side opening while portions of the wrist strap or flexible tether are removable from the interior through the side slot.
In some implementations, the insert is non-spherically shaped so as to be insertable through the side opening while at a predefined orientation. As a result, the chance of accidental dislodgment of the insert from the collar is reduced. In some implementations, the collar has major dimension along a longitudinal axis and a minor dimension less than the major dimension, wherein the side opening has a first maximum width transverse to the longitudinal axis of the collar and a second maximum width along the longitudinal axis of the collar. The insert has a major dimension along a longitudinal axis and a minor dimension, less than the major dimension, and transverse to the longitudinal axis of the insert. The major dimension of the insert is greater than the second maximum width of the side opening. The minor dimension of the insert is sized for insertion through the side opening when the longitudinal axis of the insert is perpendicular to the longitudinal axis of the collar. In some implementations, the minor dimension of the insert is less than or equal to the first maximum dimension of the side opening. In such implementations, the insert may be inserted into the collar and then rotated within the collar to an orientation in which the insert is locked into or captured within the collar.
In some implementations, the side slot has a maximum width transverse to the longitudinal axis of the collar. In some implementations, the collar is connected to the wrist strap, wherein portions of the flexible tether, connected to the sports racquet, comprise a pair of side-by-side cords and wherein the maximum width of the slot is less than a combined width of the pair of side-by-side cords.
In some implementations, at least portions of the collar are formed from a resiliently flexible polymer, facilitating resilient flexing of those portions of the collar about the side opening during pivoting or rotation of the insert within the collar. Such action provides the player with a tactile and/or audible indication of when the insert has been fully pivoted within the collar to complete the connection or to ready the insert for withdrawal from the collar. Moreover, the resilient flexibility of the collar about the side opening may facilitate a smaller size of the side opening to assist in preventing accidental dislodgment of the insert through the opening.
In some implementations, the handle of the racquet comprises a cavity extending from an end of the handle towards the head of the racquet. The flexible tether is secured to the handle within the cavity, concealing the connection of the flexible tether to the handle. Because the connection of the flexible tether to the handle is concealed, a more robust connection between the flexible tether and the handle may be provided. In some implementations, the handle further comprises an end cap, or butt cap, covering the cavity, wherein the flexible tether extends through the end cap.
In some implementations, the end of the handle comprise at least a partial ring. The flexible tether comprise a continuous cord having a fold or loop between opposite ends that are secured to one of the collar and the insert. The fold or loop is passed through the ring. Said one of the collar and insert is passed through the loop between the loop and the ring.
In some implementations, the flexible tether has an effective length of no greater than 5 mm extending from an end of the handle. For purposes of disclosure, the term “effective length” of the tether refers to the length of the tether from the axial end of the handle, and in some implementations, the end cap, to a proximal end of the insert or the collar, said one of which is directly connected to the flexible tether while the other of which is directly connected to the wrist strap. In some implementations, the flexible tether has an effective length of 2.5 mm beyond the surface of the end cap. As a result, the collar or insert directly connected to the flexible tether provides flexibility yet is sufficiently close to the axial end of the handle to reduce a likelihood of the insert and collar contacting or hitting the player's hand or wrist during play or contacting the butt end of the handle or the end cap during use. Such contact between the insert and collar and the player's hand, wrist or racquet handle might otherwise produce noise or might otherwise be annoying to the player. Moreover, in circumstances where the racquet is used without the wrist strap assembly, the short length of the tether may reduce the degree of possibly annoying dangling of the insert/collar connected directly to the tether.
In some implementations, the insert is directly connected to the flexible tether while the collar is directly connected to the wrist strap. In such implementations, the insert, sometimes referred to as a “pill”, is sized smaller than the collar, having a lesser volume. When the wrist strap is not being used, the insert hangs from an axial end of the handle. In implementations where the insert is directly connected to the flexible tether rather than the collar, the smaller sized insert may be less conspicuous than the collar, may add a lesser amount of weight to the racquet as compared to the collar, and may be less likely to contact and/or catch upon the player during play.
Disclosed is an example sports racquet and removable system. The system may comprise a head, a handle coupled to the head, a flexible tether extending from an end of the handle, a wrist strap, and a wrist strap connector releasably connecting the wrist strap to the flexible tether. The wrist strap connector includes a collar and an insert. The collar is connected to one of the wrist strap and the flexible tether and has an interior having a side opening and a side slot extending from the side opening. The insert is connected to the other of the wrist strap and the flexible tether. The insert is insertable into the interior through the side opening while portions of the wrist strap or the flexible tether are insertable into the interior through the side slot.
Disclosed is a removable wrist strap assembly for a sports racquet having a flexible tether extending from an end of a handle of the sports racquet, the flexible tether being connected to one of a collar and an insert. The wrist strap assembly may comprise a wrist strap forming a loop to receive a person's hand and wrist, and the other of the collar and the insert connected to the loop. The collar has an interior having a side opening and a side slot extending from the side opening and wherein the insert is insertable into the interior through the side opening while portions of the wrist strap or the flexible tether are insertable into the interior through the side slot.
Disclosed is an example sports racquet for use with a wrist strap. The example sports racquet may comprise a head, a handle coupled to the head, a wrist strap connector for releasably connecting to the wrist strap, and a flexible tether having an effective length extending from an end of the handle to the wrist strap connector. Because the effective length is no greater than 5 mm, the wrist strap connector is less likely to bang or rattle about, or constitute a nuisance to the player wearing the wrist strap.
Disclosed is an example sports racquet for use with a wrist strap connected to one of a collar and an insert. The sports racquet may comprise a head, a handle coupled to the head, a flexible tether extending from an end of the handle, and the other of the collar and the insert connected to the flexible tether. The collar has an interior having a side opening and a side slot extending from the side opening and wherein the insert is insertable into the interior through the side opening while portions of the wrist strap or the flexible tether are insertable into the interior through the side slot.
For purposes of this disclosure, the term “coupled” shall mean the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature. The term “operably coupled” shall mean that two members are directly or indirectly joined such that motion may be transmitted from one member to the other member directly or via intermediate members.
For purposes of this disclosure, the phrase “configured to” denotes an actual state of configuration that fundamentally ties the stated function/use to the physical characteristics of the feature proceeding the phrase “configured to”. For purposes of this disclosure, the term “releasably” or “removably” with respect to an attachment or coupling of two structures means that the two structures may be repeatedly connected and disconnected to and from one another without material damage to either of the two structures or their functioning.
Head 30 comprises that portion of racquet 24 configured to strike a projectile used in a sporting activity. Examples of such projectiles include, but are not limited to, balls (e.g., padel balls, platform tennis balls, racquetball balls, tennis balls, pickle balls and the like) and shuttlecocks. In the example illustrated, head 30 has a stringed projectile striking region 47 for striking the projectile. In the example illustrated, head 30 is illustrated as being in the form of a racquetball racquet. In other implementations, the shape and stringing pattern of head 30 may have other configurations such as where racquet 24 is in the form of a tennis racquet or other stringed racquet. In some implementations, head 30 may alternatively have a non-strung projectile striking region 47. In such implementations, racquet 24 may be in the form of a padel paddle (
Handle 34 is directly or indirectly coupled to head 30 and provides a cylindrical or polygonal shaft about which a player's hand may grasp and hold racquet 24. Handle 34 extends in a direction away from head 30, terminating at an axial end 50, or a butt end. In some implementations, handle 34 may have an outer wrap of a leather, synthetic leather, rubber, fabric or other material to facilitate gripping of handle 34. In some implementations, handle 34 may omit such an outer wrap. In some implementations, handle 34 may have an outer texture to facilitate gripping of handle 34. In some implementations, handle 34 is indirectly coupled to head 30 by throat or neck region. Handle 34 may have a variety of different sizes and lengths depending upon the sport for which racquet 24 is configured to be used.
Flexible tether 38 comprises an elongate flexible or bendable cord, band, string or other flexible line extending from axial end 50 of handle 34. In some implementations, flexible tether 38 may be formed from a leather or synthetic leather material. In some implementations, flexible leather 38 may be formed from a rubber, synthetic rubber or polymer material. In some implementation, flexible tether 38 may be formed from a natural or synthetic fiber material. Flexible tether 38 has a first portion 51 proximate to the axial end 50 and a second portion 52 coupled to insert 44. In some implementation, flexible tether 38 may be directly affixed to the axial end 50 at the axial end 50 of handle 34. Such affixation may be by adhesives, welds, fasteners, catches, a loop, a rod, a bar or hook through or about which tether 38 is tied or looped, or the like. In some implementations, first portion 51 may extend beyond axial end 50 towards head 30. For example, in some implementations, first portion 51 is secured to handle 34 at a location within a recess or cavity extending from and into axial end 50 towards head 30.
In the example illustrated, the flexible tether 38 has an effective length of no greater than 5 mm extending from end 50 of the handle 34. In some implementations, flexible tether 38 has an effective length of at least 1 mm and no greater than 5 mm, and nominally 2.5 mm. As a result, flexible tether 38 has sufficient length to facilitate manual positioning and control over the orientation of insert for facilitating the insertion and withdrawal of insert 42 with respect to a collar 48 of removable wrist strap assembly 26-1 or 26-2, yet sufficiently limited in length to reduce a likelihood of the insert 42 and collar 48 contacting or hitting the player's hand or wrist during play or contacting the butt end or axial end 50 of the handle 34 during use. Such contact between the insert 42 and collar 48 and the player's hand, wrist or racquet handle might otherwise produce noise or might otherwise be annoying to the player. In some implementations, the flexible tether 38 has an effective length of 2.5 mm beyond axial end 50. In other implementations, the tether 38 can have an effective length that is greater than 5 mm.
As shown by
Removal wrist strap assemblies 26 are configured to be releasably and interchangeably connected to racquet 24 through the interaction of insert 42 and collar 48 which cooperate to form a connector. Wrist straps 46 comprise loops sized or configured to extend about the wrist and/or hand that is grasping handle 34. Wrist straps 46 may be formed from a sweat absorbent material or a non-sweat absorbent material. Wrist straps 46 may be formed from a fabric material, a rubber material, a synthetic rubber material, a leather material, a synthetic leather material, a polymer or the like. Wrist straps 46 may comprise ropes or cords or may comprise bands.
Wrist strap 46 of the wrist strap assembly 26-1 has a different construction than the construction of wrist strap 46 of wrist strap assembly 26-2. In the example illustrated, wrist strap 46 of wrist strap assemblies 26-1 and 26-2 are differently sized. In the example illustrated, wrist strap 46 of wrist strap assembly 26-1 has a smaller diameter loop as compared to the diameter of the loop formed by wrist strap 46 of wrist strap assembly 26-2. In some implementations, the width or thickness of the different wrist straps 46 of the different wrist strap assemblies 26-126-2 may be different. For example, in implementations where wrist straps 26 comprise a band, one of wrist straps 46 may have a greater band width as compared to the other of wrist straps 46. In some implementations, wrist straps 46 of assemblies 26-1 and 26-2 are formed from different materials having different properties, such as different elasticity properties or different moisture absorbing properties. In other implementations, the wrist strap 46 may have a slip knot or looped structure that readily adjusts to the size of the user's wrist when worn.
Collar 48 and insert 42 form a wrist strap connector. Collars 48 of wrist strap assemblies 26 are similar to one another.
In other implementations where insert 42 is to have other shapes, portion 56 of interior 54 may also have a different shape configured to receive insert 42. In the example illustrated, portion 56 has a shape corresponding to the shape of insert 42. In other implementations, portion 56 of interior 54 may have shapes that do not necessarily correspond to the shape of insert 42, but which are sized to receive insert 42. Tether passage 58 of interior 54 extends from portion 56 to and through an axial end 70 of body 53.
Side slot 62 is in communication with or opens into portion 58 of interior 54. Side slot 62 extends from side opening 60 to and through the axial end 70 of collar 48. Side slot 62 is configured to receive flexible tether 38 such that flexible tether 38 may extend from insert 42 (received within portion 56 of interior) out an axial end 70 of collar 48. In some implementations, side slot 62 has a width W5 greater than a corresponding width of flexible tether 38. In implementations, side slot 62 has a width W5 less than the width W3 and less than the width of flexible tether 38, wherein edge portions of side slot resiliently flex during insertion of tether 38 and/or wherein the diameter or thickness of tether 38 may be temporarily reduced during insertion such as by placing tether 38 in tension or pushing tether 38 through side slot 62.
In such implementations, portions of body 53 along side slot 62 may be resiliently flexible to accommodate the sideways insertion of flexible tether 38 through side slot 62 or the sideways withdrawal of flexible tether 38 through side slot 62. In some implementations, body 53 may be formed from an inflexible mass of material, but wherein regions of body 53 adjacent to side slot 62 are sufficiently thin or otherwise dimensioned so as to be resiliently flexible. In other implementations, the outer perimeter of side slot 62 may be formed from a material different than remaining portions of body 53. In some implementations, the outer edge of side slot 62 may have a resiliently flexible lip formed from a resiliently flexible material that is over molded or otherwise affixed to the remainder of body 53. For example, the outer edge of side slot 62 may be formed from a rubber, a synthetic rubber or other material that may be more resiliently flexible or elastic as compared to remaining portions of body 53.
In some implementations, the width W3 or the width W5 can be sized to receive only one portion of the tether 38. In other words, the tether 38 is typically a looped cord which has two portion extending from the insert or pill 42. In such implementations, the only way for the tether 38 to extend through the side slot 62 is if the tether portions enter the side slot 62 one at a time (one before the other) because the width W3 or W5 is too small to allow both portions of the tether 38 to enter the side slot 62 side by side. Such a configuration further inhibits the inadvertent disconnection or release of the strap assembly 26 from the handle 34.

When the currently connected wrist strap assembly 26-1 is to be disconnected from racquet 24, the reverse process may be carried out. In particular, insert 42 is first rotated about axis 70 in the direction indicated by arrow 78 in
Collar 148 is similar to collar 48 except that side opening 60 is smaller and that portions of collar 148 adjacent to or about side opening 60 are resiliently flexible. In the example illustrated, those portions of body 53 adjacent to side opening 60 are resiliently flexible to flex during insertion of insert 42 into and withdrawal of insert 42 from portion 56 of interior 54. In the example illustrated, body 53, or at least portions of body 53 about side opening 60 are formed from a resiliently flexible material configured to resiliently flex in response to pivoting of insert 42 within interior portion 56. As shown by
In some implementations, body 53 may be formed from an inflexible mass of material, but wherein regions of body 53 adjacent to side opening 60 are sufficiently thin or otherwise dimensioned so as to be resiliently flexible. In other implementations, portion 149 adjacent to side opening 60 may be formed from a material different than remaining portions of body 53. In some implementations, portion 149 may comprise a resiliently flexible lip formed from a resiliently flexible material that is over molded or otherwise affixed to the remainder of body 53. For example, portion 149 may be formed from a rubber, a synthetic rubber or other material that may be more resiliently flexible or elastic as compared to remaining portions of body 53.
Insert 42 and collar 48 facilitate quick and easy disconnection of wrist strap assembly 26-1 from racquet 24. As a result, a player may disconnect the wrist strap assembly 26-1 when the player no longer wishes to use the wrist strap 26-1. The player may also easily and quickly replace or exchange the wrist strap 26-1 in circumstances such as when the wrist strap has become sweaty during play, such as when the wrist strap has been damaged and needs replacement, or such as when the player desires a different wrist strap, such as wrist strap assembly 26-2, having a different size or formed from a different material.
As shown by
Similar to system 20, system 120 facilitates quick and easy disconnection of wrist strap assembly 26-1 from racquet 24. As a result, a player may disconnect the wrist strap assembly 126 when the player no longer wishes to use the wrist strap assembly 126. The player may also easily and quickly replace or exchange the wrist strap assembly 126 in circumstances such as when the wrist strap has become sweaty during play, such as when the wrist strap assembly 126 has been damaged and needs replacement, or such as when the player desires a different wrist strap assembly having a different wrist strap size or a wrist strap formed from a different material.
Head 230 is similar to head 30 described above in that head 230 comprise a widened and enlarged portion of racquet 224 configured for striking a projectile. In contrast to head 30, head 230 comprises a non-strung projectile striking region 246. In some implementations, region 246 is imperforate. In some implementations, region 246 may include perforations or openings. In some implementations, head 230 may be configured as part of a padel paddle, a pickle ball paddle, a platform tennis paddle or other forms of paddles which utilize solid, hollow, celled, or non-strung projectile striking regions. As should be appreciated, the size, shape and exact nature of head 230 may vary depending upon the projectile to be struck and the sport in which racquet or paddle 224 is to be used.
Handle 234 is similar to handle 34 in that handle 234 provides a cylindrical or polygonal shaft about which a player's hand may grasp and hold racquet 224. Handle 234 extends in a direction away from head 30, terminating at an axial end 250, or butt end. In some implementations, handle 234 may have an outer wrap of a leather, synthetic leather, rubber, fabric or other material to facilitate gripping of handle 234. In some implementations, handle 234 may omit such an outer wrap. In some implementations, handle 234 may have an outer texture to facilitate gripping of handle 234. In some implementations, handle 34 is indirectly coupled to head 230 by throat or neck region. Handle 234 may variety of different sizes and lengths depending upon the sport for which racquet 224 is configured to be used.
As shown by
Flexible tether 238 comprises an elongate flexible or bendable cord, band, string or other flexible line having a first portion 251 secured to rod 300 within cavity 300 and a second portion 252 secured to insert 242. In the example illustrated, flexible tether 238 comprises a single line, the opposite ends of which are both affixed to insert 242. In some implementations, those portions of flexible tether 238 between the ends secured to insert 242, form a loop which wraps about rod 302. In some implementations, an entirety of the loop is wrapped about rod 302, wherein insert 242 is then passed through the loop, between rod 302 and the loop to secure flexible tether 238 to rod 302. In yet other implementations, flexible tether 238 may be secured to rod 302 or other structures within cavity 300 in other fashions.
In some implementations, flexible tether 238 may be formed from a leather or synthetic leather material. In some implementations, flexible leather 238 may be formed from a rubber, synthetic rubber or polymer material. In some implementations, flexible tether 38 may be formed from a natural or synthetic fiber material.
In the example illustrated, the flexible tether 238 has an effective length of no greater than 5 mm extending from an end 250 of the handle 234. In some implementations, flexible tether has an effective length of at least 1 mm and no greater than 5 mm, and nominally 2.5 mm. As a result, flexible tether 238 has sufficient length to facilitate manual positioning and control over the orientation of insert 242 for facilitating the insertion and withdrawal of insert 242 with respect to a collar 248 of removal wrist strap assembly 226, yet sufficiently limited in length to reduce a likelihood of the insert 242 and collar 248 contacting or hitting the player's hand or wrist during play or contacting the butt end or axial end 250 of the handle 234 during use. Such contact between the insert 242 and collar 248 and the player's hand, wrist or racquet handle might otherwise produce noise or might otherwise be annoying to the player. In some implementations, the flexible tether 238 has an effective length of 2.5 mm beyond axial end 250. In other implementations, the tether 238 can have a length greater than 5 mm.

As shown by
Collar 248 is connected to end 314 of strap 310.
Collar 248 further comprises side opening 260 and side slot 262. Side opening 260 extends through a side of body 253 and opens into interior 254. In the example illustrated, side opening 260 comprises a circular opening having a diameter equal to or slightly larger than diameter D1 of insert 242 but less than the length L1 of insert 242. Although illustrated as being circular, in other implementations, side opening 260 may have other shapes while limiting the insertion of insert 242 into interior 254 to a predefined orientation or set of orientations.
Side slot 262 extends from side opening 260 to the end 255 of collar 248. Side slot 262 opens into the interior 254. In the example illustrated, side slot 262 is sized to allow flexible tether 238 (shown in
In other implementations, side slot 262 may have other widths. For example, side slot 262 may have a width which may necessitate constriction of each of lines 238-1 and 23-2 during consecutive passage of the lines of flexible tether 238 through side slot 262 (requiring one by one passage of the lines 238-1 and 238-2 through the side slot 262). In some implementations, side slot 262 may have a greater width to allow concurrent side-by-side passage of lines 238-1 and 238-2 through side slot 262. In some implementations, flexible tether 238 may be formed from a single line rather than a pair of lines.
In some implementations, portions of collar 248 adjacent to or about side opening 260, such as portions 261 shown in

To disconnect racquet 224 from removable wrist strap assembly 226, insert 242 is removed from the interior 254 of collar 248. When the currently connected wrist strap assembly 226 is to be disconnected from racquet 224, the reverse process may be carried out. In particular, insert 242 is first rotated so as to pull flexible tether 38 through side slot 262. During such pulling, lines 238-1 and 238-2 of tether 238 are stacked so as to consecutively pass through side slot 262. Pulling of flexible tether 238 through side slot 262 pivots insert 242 from the position shown in
Collar 448 is similar to collar 48 described above except that collar 448 comprises side opening 460 and side slot 462. Side opening 460 is sized smaller than insert 42, but is bordered by resiliently flexible rim 465. Rim 465 extends about side opening 460 and is sufficiently large and sufficiently flexible so as to bend or flex during the insertion of insert 42 into the interior 54 of collar 448 as indicated by arrow 467. Likewise, rim 465 is sufficiently large and sufficiently flexible so as to bend or flex during the withdrawal of insert 42 from the interior 54 of collar 448. As a result, insert 42 may be inserted into interior 54 in a sideways orientation, wherein axis 66 of insert 42 is parallel to axis 68 of collar 448. Upon full insertion of insert 42 into interior 54, rim 465 resiliently returns to its initial shape (shown in
Side slot 462 has a width less than a corresponding with of flexible tether 38. In the example illustrated, side slot 462 is likewise bordered by resiliently flexible edges 467. Edges 467 are resiliently flexible so as to bend during manual insertion of flexible tether 38 through side slot 462 or doing withdrawal of flexible tether 38 through side slot 462. In some implementations, the resilient flexible nature of edges 467 may be achieved by providing edges 467 with a reduced thickness to facilitate such flexing. In other implementations, edges 467 may be formed from a material different than the remaining material of body 53, wherein edges 467 or otherwise affixed to or over molded with respect to the remainder of body 53. Edges 467 facilitate passage of flexible tether 38 into tether passage 58 of interior 54 while assisting in retaining flexible tether 38 within tether passage 58 once inserted.
Collar 558 is similar collar 448 described above except that collar 558 comprises side opening 560 and side slot 562. Side opening 560 and side slot 562 are each sufficiently large for the passage of insert 42 and flexible tether 38, respectively, in a sideways fashion into the interior 54 of collar 558. Each of side opening 460 and side slot 462 have inflexible rims or edges.
As shown by
Outer sleeve 582 comprises overhanging portions 584 that project over side opening 460 and which are sufficiently large and sufficiently flexible so as to bend to allow insert 42 to be inserted in a sideways fashion through side opening 582 as indicated by arrow 567. Likewise, flexible tether 38 may also be moved in a sideways fashion through side slot 584. As a result, insert 42 may be inserted into interior 54 in a sideways orientation, wherein axis 66 of insert 42 is parallel to axis 68 of collar 448. Upon full insertion of insert 42 into interior 54, overhanging portions 582 resiliently return to their initial shape to inhibit inadvertent withdrawal of insert 42 through side opening 582. In the example illustrated, overhanging portions 582 are sufficiently flexible to allow insert 42 to be manually pushed through side opening 582 while flexing overhanging portions 584, yet sufficiently rigid to inhibit insert 42 from accidentally falling through overhanging portions 584.
Collar 648 similar collar 548 described above except that collar 648 omits outer sleeve 580. In addition, collar 648 has an extended interior 654, having a length extending from side opening 560 to the axial end 670 which is sufficiently long for receiving at least a majority, and in some implementations, the entirety of the axial length of insert 42. As a result, insert 42 may be inserted through side opening 560 in the direction indicated by arrow 667. Thereafter, insert 42 may be pulled in the direction indicated by arrow 669 until insert 42 has been moved into an insert holding region 670 below side slot 562. Because forces experienced by system 620 are largely in the direction indicated by arrows 674, insert 42 is unlikely to accidentally move in both a direction opposite to arrow 69 and in a direction opposite to arrow 667.
In the example illustrated, system 620 additionally comprises an extension post 676 coupled between insert 42 and flexible tether 38. Extension post 676 has a lower degree of flexibility as compared to flexible tether 38. Extension post 676 assists in facilitating the withdrawal of insert 42 from the interior 654 of collar 648. In particular, extension post 676 may be manually grassed pushed in a direction opposite arrow 669 until insert 42 is aligned below side opening 560. Thereafter, insert 42 may be lifted through side opening 560 in a direction opposite to that of arrow 667. In some implementations, extension post 676 has a length equal to or greater than the extended length of interior 654 which forms insert holding region 670. This extended length facilitates manual gripping of post 676 to lift insert 42 through side opening 560 and to likewise move extension post 676 through side slot 562. In some implementations, extension post 676 may be omitted, wherein flexible tether 38 is directly connected to insert 42.
As shown by stippling, in some implementations, collar 648 may additionally comprise a resiliently flexible rubber-like lip 678 about the axial opening 680 through which extension post 676 (or tether 38) extends). Lip 678 assist in gripping post 676 to inhibit accidental sliding movement of post 676 and of insert 42 in a direction opposite arrow 669. Lip 678 assists in retaining insert 42 in the insert holding region 670, inhibiting insert 42 from accidentally sliding to the left so as to underlie side opening 560.
Wrist strap connector 742 comprise a member secured to the end of tether 238 and having a passage 754 (shown in broken lines) therethrough. Passage 754 is sufficiently dimensioned or sized such that portions of wrist strap assembly 726 may be threaded or passed through passage 754 to facilitate releasable securement of wrist strap assembly 726 to strap connector 742 and sports racquet 724.
Wrist strap assembly 726 is similar to wrist strap assembly 226 described above except that strap 310 has an end portion secured to or forming part of a flexible loop 748 rather than collar 248. Flexible loop 748 is sufficiently sized and compressible so as to be threadable through passage 754 of wrist strap connector 742. Flexible loop 748 is sufficiently sized such that strap 310 and padding 312 may be passed through loop 748. In some implementations, padding 312 may be omitted, wherein strap 310 itself forms a loop for receiving the hand and wrist of a person or player using system 720. As shown by
Wrist strap assembly 826 is similar to wrist strap assembly 726 described above except that strap 310 omits padding 312 while forming a wrist receiving loop 311 and has an end portion secured to buckle 848 (portions of which are shown in section). Strap 310 and wrist receiving loop 311 are sufficiently thin or small and compressible so as to be capable of being threaded through passage buckle 848. As shown by
Wrist strap assembly 926 is similar to wrist strap assembly 826 described above except that wrist strap assembly 926 comprises snap or lock connector 948 in place of buckle 848. Those remaining components of system 920 which correspond to components of system 820 are numbered similarly.
Connector 948 is secured to an end 960 of cord or strap 310 while releasably gripping an intermediate portion of strap 310 which passes through connector 948. Connector 948 may grip strap 310 at any of a multitude of different locations along the length of strap 310, allowing the distance between the wrist receiving loop 311 and wrist strap connector 742 to be adjustable to suit the player's preferences. In the example illustrated, connector 948 comprises a single hole spring-loaded cord lock.
To disconnect wrist strap assembly 926 from sports racquet 724, piston 976 may be manually depressed to align openings 972 and 978 such that loop 311 may be passed through such openings. Thereafter, loop 311 may be passed through passage 754 to disconnect wrist strap assembly 926 from sports racquet 724.
Sports racquet 724 comprises head 30 or 230, shown in
Wrist strap connector 1042 comprise a first member or portion of a plastic quick side release connector, such as plastic side release buckle. Connector 1042 is secured to tether 238.
Wrist strap assembly 1026 is similar to wrist strap assembly 226 described above except that strap 310 has an end portion secured to a second member or second portion of a plastic quick side release connector 1048, such as a plastic side release buckle. Connectors 1042 and 1048, schematically shown, may comprise a “male” connector or buckle member, the hook end, and a “female” buckle or connector member, the insertion end. Pressing in on the sides of the connector buckle, pressing the two resilient plastic side prongs of the male connector, into the side openings of the female connector of the female connector member causes the side release connector or buckle to release, allowing the wrist strap assembly 1026 to be disconnected from and separated from sports racquet 724.
In some implementations connector 1048 may comprise a buckle that grips cord 310 and that allows cord 3102B slid through the buckle, adjusting a distance between loop 311 and connector 1042 and sports racquet 724. In some limitations, connectors 1042 comprises the male connector of the side release buckle or connector. In some implementations, connector 1042 comprises the female or insert portion of the side release buckle or connector.
Although the present disclosure has been described with reference to example implementations, workers skilled in the art will recognize that changes may be made in form and detail without departing from the scope of the claimed subject matter. For example, although different example implementations may have been described as including features providing benefits, it is contemplated that the described features may be interchanged with one another or alternatively be combined with one another in the described example implementations or in other alternative implementations. Because the technology of the present disclosure is relatively complex, not all changes in the technology are foreseeable. The present disclosure described with reference to the example implementations and set forth in the following claims is manifestly intended to be as broad as possible. For example, unless specifically otherwise noted, the claims reciting a single particular element also encompass a plurality of such particular elements. The terms “first”, “second”, “third” and so on in the claims merely distinguish different elements and, unless otherwise stated, are not to be specifically associated with a particular order or particular numbering of elements in the disclosure.
