Title: Swing training device

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Application 63/275,153, filed on Nov. 3, 2021, the entire contents of which is incorporated herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosure herein generally relates to a training device for sports performance, and more particularly, to a training device for improving the swinging technique of a golf player. 
     BACKGROUND 
     In many ball-related sports, such as golf, baseball, and hockey, players often swing a sports implement (e.g. a club, stick, or bat) at high speeds. A player often benefits from swinging the sports implement in a consistent manner, as it allows for increased control in performing the sport. Frequently, both the amount of force applied by the sports implement as well as the consistency in which a player can swing the sports implement are highly dependent on having a desirable swinging form or technique. 
     One aspect of a desirable swinging technique with sports implements, for example a golf club, is for the forearms of the player to stay in close proximity with each other for the duration of the swing. “Shallowing the golf club” refers to a desirable trait of a golf swing, where the rotation of the golf club is maximized horizontally during the downswing. Many amateur or inexperienced golfers tend to swing towards the golf ball in a vertical motion (“chopping”), where the head of the golf club is directly or nearly directly above the handle of the club during the downswing motion. Training a golfer’s forearms to stay close together during the swing may help encourage a shallow swing. 
     Accordingly, a need exists for an improved swing training device for sports training, which provides for precise size adjustment and usability for a wide range of body types. 
     SUMMARY 
     The terms “invention,” “the invention,” “this invention” and “the present invention” used in this patent are intended to refer broadly to all of the subject matter of this patent and the patent claims below. Statements containing these terms should be understood not to limit the subject matter described therein or to limit the meaning or scope of the patent claims below. Embodiments of the invention covered by this patent are defined by the below, not this summary. This summary is a high-level overview of various aspects of the invention and introduces some of the concepts that are further described in the Detailed Description section below. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used in isolation to determine the scope of the claimed subject matter. The subject matter should be understood by reference to appropriate portions of the entire specification of this patent, any or all drawings and each claim. 
     Aspects of the present disclosure are related to a swing training device with adjustable sizing capabilities. In particular, embodiments of the present disclosure provide for a golf swing training device with a body portion having a surface sized and shaped to receive the forearms of a user. The swing training device can be coupled to an appendage of the user, for example the user’s forearm, via a strap or other securing feature. The swing training device can have an first end region that overlaps a second end region to form an overlapping loop, or, in use, a generally hollow, cylindrical shape. The first end region can be coupled to the second end region such that the respective end regions may slide relative to one another upon an application of force by the user’s forearms, thereby altering the diameter of an inner region of the body. The body of the swing training device may be size-adjustable to allow for the body to precisely fit between the forearms of a particular user by allowing the first end region to slide relative to the second end region along a length of a slot in the body. The device may provide tactile feedback via the movement of the first end region relative to the second end region to aid in training the user to maintain their elbows in close proximity to each other during a golf swing. 
     In one aspect, the body of the swing training device has an elongated, curved shape (e.g. a loop, c-shape, or open circle) defining a first end region and second end region at a first end and a second end of the body, respectively. The shape of the body may allow for the end regions to adjustably overlap one another, such that the circumference of the body may decrease, providing size adjustability. As such, when positioned between the forearms of a user, pressure may be applied to the outer surface of the body, causing an increase in the overlap between the end regions. From a side perspective, an outer surface of the body may have a concave shape to conform to the shape of a forearm of a user. The body may be constructed from a flexible or otherwise temporarily deformable material, and thus may be configured to bend or flex. 
     In one aspect, the body may include a receiving slot which extends circumferentially around at least a portion of the body, such as spanning near the second end region of the body. The first end region and second end region of the body may be overlapped, and an attachment member may be inserted through an opening in the first end region and the receiving slot adjacent the second end region, such that the end regions are coupled together. While coupled via the attachment members, the end regions may still move or slide horizontally relative to each other, by the attachment member moving horizontally within the receiving slot along a length of the second end region. The attachment member may be relatively fixed in place relative to the first end region as it passed through the opening in the body adjacent or proximate to the first end region. As such, the diameter of the inner area of the body may be adjusted via movement of the attachment member along the length of the receiving slot. In various embodiments, the attachment member may include a bolt and a fastener. 
     In one aspect, the swing training device may include a comfort member, dimensioned to attach to attach to at least a portion of the outside of the body. The comfort member may provide cushioning or reduce fiction between the body of the swing training device and the forearms of the user. 
     In one aspect, the swing training device may include an arm attachment which couples to the body of the swing training device. For example, the arm attachment may be a strap, belt, an elastic band, a Velcro strap, or similar device to attach the swing training device to the forearm of the user. 
     An embodiment of the present invention relates to a swing training device for practicing a sports swing that include a body having a first end region and a second end region, and a receiving slot extending along a length of the body. At least one attachment member is received within the slot and adapted to couple the first end region and the second end region to define a hollow shape. In some embodiments, the first end region and the second end region are adapted to translate relative to each other to alter the hollow shape itself and/or the area of the hollow shape.

     DETAILED DESCRIPTION 
       FIGS.  1  and  2    illustrate front and rear prospective views, respectively, of an exemplary swing training device  100 , for example a golf swing training device, according to various embodiments of the present disclosure. The swing training device  100  may include a body  102  having, in use, a generally hollow, cylindrical shape defining a first end  106  and a second end  110 . For example, the body  102  may have an open loop shape, such as a c-shape or open circle, though in some aspects the body  102   may form a complete loop. The swing training device  100  may have an interior area  104  which is open (hollow). As shown in  FIGS.  3 - 5   , which depicts the body  102  in a perspective, top, and side view respectively, the body  102  may have a first end region  108  proximate the first end  106  and a second end region  112  proximate the second end  110 . The body  102  may be dimensioned such that the first end  106  is radially distanced from the interior area  104  more than the second end  110  (or vice versa), such that the first end region  108  may overlap on top of the second end region  112  (see, e.g.,  FIGS.  6  and  7   ). For example, when force or pressure is applied to the exterior surface  114  of the body  102 , the first end region  108  may overlap (or further overlap) the second end region  112 , such that the diameter of the interior area  104  of the body  102  decreases. Similarly, when the force or pressure is removed or reduced, the first end region  108  and second end region  112  may move relative to each other such that the diameter of the interior area  104  increases. 
     The exterior surface  114  of the body  102  may be a concave, hyperboloid or hour-glass shape. For example, the concave shape of the exterior surface  114  may provide a surface that conforms to the shape of a forearm or forearms of a user. 
     The body  102  may be constructed from a flexible or otherwise temporarily deformable material, and thus may be configured to bend. In some aspects, the body  102  may be flexible to deform to a generally linear shape, such that the first end region  108  and second end region  112  are planar and opposite each other. For example, providing flexibility may allow for the swing training device  100  to be more compact for storage and shipping purposes. In various embodiments, the body  102  may not be flexible enough to allow the body  102  to deform to a linear shape, such that the body  102  is more rigid for use. 
     The body  102  may further include a receiving slot  116  having a first end  118  and a second end  120  opposite the first end  118 . The receiving slot  116  may extend partially or entirely through the thickness of the body  102 . The receiving slot  116  may extend circumferentially around at least a portion of the body  102 . In various aspects, the receiving slot  116  may extend around between 25% to 75% of the circumference of the body  102 . However, the receiving slot  116  may extend around less or more of the circumference of the body  102 . The first end  118  of the receiving slot  116  may be, but does not have to be, positioned more proximate the second end  110  of the body  102  than the first end  106 . As such, the receiving slot  116  may be circumferentially more proximate the second end  110  than the first end  106 . In various aspects, the receiving slot  116  may extend at a uniform height along the body  102  in that the receiving slot  116  is located a distance from one of the top or bottom edges of the body  102  that is consistent along the length of the receiving slot  116 . However, in other embodiments, such distance may vary along the length of the receiving slot  116 . 
     The body  102  may include an opening  122  proximate to the first end  106 . When the first end region  108  and the second end region  112  are sufficiently overlapped, the opening  122  may align with a portion of the receiving slot  116  such that one or more attachment members may extend through the opening  122  and the receiving slot  116  to couple the first end region  108  and the second end region  112 . The movement of the first end region  108  and the second end region  112  may be limited by the one or more attachment members, for example to retain the end regions  108 ,  112  in an overlapped position. In some aspects, the one or more attachment members may be moveable to various positions within the receiving slot  116  such that the first end region  108  and second end region  112  may be adjustably overlapped with one another, permitting the diameter of the body  102  to vary. Exemplary, non-limiting, attachment members are discussed in detail below. 
     In various aspects, the swing training device  100  may include a comfort member  124 , which may be dimensioned to attach or couple to the exterior surface  114  of the body  102 . The comfort member  124  may wrap partially or entirely around the circumference of the exterior surface  114  of the body  102 . In various aspects, the comfort member  124  may be removable from the body  102 , such as for cleaning or replacement. The comfort member  124  may be made from a foam material, a deformable plastic, fabric, or similar material to provide comfort to the forearms of the user during use. Similarly, the comfort member  124  may be made of a material which reduces friction between the forearms of the user and the body  102  of the swing training device  100 , to prevent or reduce rubbing or chafing of the forearms. 
     In various aspects, the swing training device  100  may include an arm attachment  126  which couples the body  102  of the swing training device  100  to the user. For example, the body  102  may include openings to provide for the arm attachment  126  to loop or otherwise attach to the body  102 . As shown in  FIGS.  9  and  10   , which illustrates the arm attachment  126  in a perspective view and a side view, the arm attachment  126  may be, for example, a strap, belt, an elastic band, a Velcro strap, or similar device. Functionally, the arm attachment  126  may attach to the forearm of a user to removably attach the swing training device  100  to the user. In various embodiments, the swing training device  100  may include a plurality of arm attachments  126  which may attach to the same forearm of a user or may attach to both arms of the user. 
     The arm attachment  126  may receive a forearm of a user. For example, in some aspects the arm attachment  126  may include a belt or Velcro. In such aspects, the belt may be loosened for inserting the arm and then retightened to the desired tightness, such that the swing training device  100  is secured to the arm. The swing training device  100  may be attached to either forearm (or in some aspects, both forearms) of the user. For example, the swing training device may be coupled to the “front forearm” of the user - the arm facing towards the direction they wish to project the ball (generally the non-dominant arm). In such aspects, by only attaching the swing training device  100  to one arm, the user may still retain full function of their arms, such that the user may be able to change clubs, or perform other tasks with their arms, without their arms being bound together by the training device  100 . 
     In some aspects, the swing training device  100  may not include an arm attachment  126 . The body  102  of the swing training device  100  may be placed between the forearms of the user and maintained in position by pressure applied between the forearms. 
       FIGS.  6 - 8    illustrates the assembled swing training device  100  The swing training device  100  may include one or more attachment members  202 . As discussed above, the opening  122  in the body  102  proximal to the first end  106  may be aligned with a portion of the receiving slot  116  such that the one or more attachment members  202  may be inserted through the receiving slot  116  and the opening  122 . The one or more attachment members  202  may include, for example, a bolt  204  which may be inserted through the opening  122  from the exterior surface  114  of the body  102 . The bolt  204  may include a shaft  206  including a threaded portion  208  at the distal end of the shaft  206 , and an unthreaded portion proximal to the head of the bolt  204 . The bolt  204  may be positioned through the opening  122  and through the receiving slot  116 . For example, the threaded portion  208  of the bolt  204  may not extend all the way to the proximal portion of the bolt  204  (near the head), thus the shaft  206  may have a neck portion, near the head of the bolt  204 , which does not have threading. This section may be cylindrical (e.g. a shank) or may otherwise include a stop (e.g. a square neck). For example, the bolt  204  may be a carriage bolt, having a rounded head and square neck. To accommodate these different designs of the bolt  204 , the opening  122  and/or the receiving slot  116  may be sized and shaped appropriately to receive the bolt  204 . For example, the opening  122  may be square for a bolt  204  having a square neck, or the opening  122  may be round to receive a bolt  204  with a cylindrical shank. 
     While discussed herein that the body  102  may include the opening  122 , this feature does not require that the bolt  204  be removable from the body  102 . In various embodiments, the bolt  204  may be permanently attached to (or incorporated in) the first end region  108  of the body  102 , and thus may be incorporated as a component of the body  102 . 
     The one or more attachment members  202  may further include a fastener  220  which may thread on to the distal end of the bolt  204  to retain the bolt within the receiving slot  116 . In some aspects, the fastener  220  may be fully tightened (threaded) on the bolt  204 , and yet the fastener  220  may not fully tighten against the head of the bolt  204 . For example, the unthreaded portion of the shaft  206  of the bolt  204  may inhibit the fastener  220  from contacting the head of the bolt  204 , such that a space is maintained. As such, the unthreaded portion of the shaft  206  may be configured to at least extend through the receiving slot  116  of the second end region  112 , such that the second end region  112  is not fully secured relative to the first end region  108  and may therefore slide relative to the first end region  108  as the attachment member  202  slides within the receiving slot  116 . 
     In various aspects, the location of the bolt  204  and fastener  220  may be reversed, such that the bolt  204  is inserted through the receiving slot  116  and opening  122  towards the exterior surface  114 . Further, while specific features of the bolt  204  and fastener  220  are discussed herein at length, further embodiments are contemplated for alternative attachment members  202  to provide the function of the bolt  204  and faster  220  discussed herein. For example, various attachment devices may be used to hold the first end region  108  over the second end region  112  yet still allow relative sliding between the two regions  108 ,  112  so as to vary the diameter of the body  102 . Various latching mechanisms, fasteners, clips, snaps, hooks, and locking devices are contemplated to perform this function. 
     The one or more attachment members  202  may restrict movement of the first end region  108  and the second end region  112  relative to each other. More specifically, the attachment member  202  may prevent the first end region  108  and the second end region  112  from sliding relative to each other beyond the first end  118  and the second end  120  of the receiving slot  116 . In this way, a maximum and minimum diameter of the body  102  is defined. Said interaction is shown in  FIG.  6    and  FIG.  7   , which depict a perspective view of the swing training device  100  with the attachment member  202  positioned in different locations along the length of the receiving slot  116 . 
     The attachment members  202  may be selected with specific dimensional characteristics to provide the desired friction between the first end region  108  and the second end region  112 . For example, when using the swing training device  100 , it may be desirable to have some friction between the first end region  108  and second end region  112  to provide “resistance.” Thus, when the user is swinging a sports implement (e.g. golf club) with the swing training device  100 , if the forearms of the user separate (i.e. due to poor form) the body  102  of the swing training device  100  does not immediately expand. As such, the resistance provides tactile feedback to the user that they have separated their forearms from contact with the body  102  of the swing training device  100 . Conversely, as discussed below, the user may apply pressure on the exterior surface  114  of the body  102  to conform the size of the body  102  to the spacing between the forearms of the user. As such, it is desirable for the friction to not be so high that a user has difficultly in adjusting such sizing of the body  102 . 
     The swing training device  100  may optionally include one or more pads  210 , which may be attached to either or both of the first end region  108  and/or the second end region  112 . The pads  210  may be interposed between the first end region  108  and the second end region  112 . For example, the pads  210  may be made of a material configured to reduce or limit friction between the first end region  108  and the second end region  112 , such that the first end region  108  and second end region  112  may slide with less force relative to each other. The pads  210  may not be included in the switch training device  100 , for example where the first end region  108  and the second end region  112  slide relative to one another with a sufficiently low frictional resistance. 
       FIGS.  11 A- 11 C  illustrate the swing training device  100  in various use positions as a user  302  swings a golf club  304 . 
       FIG.  11 A  illustrates the position of the swing training device  100  when a swing of a user  302  is at a starting position  306 . In the starting position  306 , the golf club  304  may be positioned facing downwards such that the head  308  of the golf club  304  is stationary near the ground. In various embodiments, the head  308  may be positioned relative to a golf ball, such as to align the swing of the user  302  with the golf ball. Similar orientations may be utilized for various sports, as discussed above. 
     As shown in  FIG.  11 A , in the starting position  306 , the swing training device  100  may be attached to the forearm  310  of the user  302  with the arm attachment  126 . As shown in the figure, the arm attachment  126  attaches the swing training device  100  to one of the forearms  310 , specifically the front (or lead) forearm. In various embodiments, the arm attachment  126  may attach to the back forearm, or to both forearms. As shown in the figure, the comfort member  124  contacts each of the forearms  310  of the user  302 . Specifically, the forearms  310  fit within the concave outer shape of the exterior surface  114  of the body  102 . 
     While positioned between the forearms  310 , the first end region  108  overlaps the second end region  112 , and the first end region  108  and the second end region  112  are coupled together via one or more attachment members  202 . Specifically, a fastener  220  (e.g. a nut) is shown within the interior area  104  of the body, and is attached to the bolt  204  extending through the receiving slot  116 . 
     When pressure is applied by the forearms  310  of the user  302  on the body  102  of the swing training device  100 , the interior area  104  of the body  102  contracts. For example, the body  102  may assume a more elongated cross-sectional shape, such as an oval shape, where a first cross-wise dimension of the interior area  104  (e.g., the height) decreases and a second cross-wise dimension of the interior area  104  (e.g., the width) increases as a result of the pressure on the body  102  by the forearms  310 . Alternatively, the interior area  104  may stay generally circular but the area of the interior area  104  may be reduced when the body  102  is subjected to pressure. 
       FIG.  11 B  shows the user  302  in a backswing position  312  such that the golf club  304  is positioned behind the user  302  and is facing substantially upwards. In the backswing position  312 , the swing training device  100  is maintained between the forearms  310  of the user  302  by the arm attachment  126  and the pressure or force exerted by the user’s forearms  310 . Between the starting position  306  and the backswing position  312 , if the amount of force applied by the forearms  310  of the user  302  on the body  102  increases, the first end region  108  and second end region  112  may overlap further, as the attachment member(s)  202  slide in a first direction within the receiving slot  116 , such that the diameter of the interior area  104  decreases. Conversely, if the force applied on the body  102  is decreased, the first end region  108  and second end region  112  may overlap less, as the attachment members  202  slide in a second direction within the receiving slot  116 , such that the diameter of the interior area  104  increases. As such, the position of the elbows  314  may continue to adjust the amount of overlap between the first end region  108  and the second end region  112  throughout the swing of the golf club  304 . 
       FIG.  11 C  shows the user  302  in a forward swing position  316 , where the golf club  304  is moving forward from the backswing position  312  and downward such that the head  308  of the golf club  304  approaches the ground in front of the user  302 . The body  102  of the swing training device  100  may maintain the same or similar interior area  104  as in the starting position  306  or as in the backswing position  312 . Alternatively, based on the amount of force applied on the body  102  of the swing training device  100  by the user’s forearms  310 , the amount of overlap between the first end region  108  and second end region  112  may change (increase or decrease). As discussed previously, the body  102  of the swing training device  100  may provide “resistance” (at least partially) during the swing of the golf club  304 , such that if pressure if reduced by the forearms  310  on the body  102 , the body  102  may maintain a similar interior area  104  throughout the swing. This process may be continued for repeated swings of the golf club  304 , and then removed from the forearm(s)  310 . 
     While discussed herein that the swing training device  100  includes a first end region  108  and second end region  112  which overlap, it is further contemplated that the body  102  of the swing training device  100  may be a closed loop shape, which is fully connected circumferentially, for example by an end of the device being received in a slot or opening in a second end of the device. As such, the interior area  104  may be adjusted by similarly applying force on the exterior surface  114 , which may cause the exterior surface  114  to deform (such as due to deformable material) to provide an appropriate spacing (sizing) for the swing training device  100  between forearms  310  of the user  302 . 
     While discussed herein that a first end region  108  and a second end region  112  may move relative to one another even while coupled together via attachment members  202 , in some aspects the first end region  108  and second end region  112  may be fixedly positioned relative to one another when coupled together via the attachment members  202 . In such an aspect, the attachment members  202  may not slide within the receiving slot  116 , though the swing training device  100  may still be sized to a particular user  302  based on the selected fixed position of the end regions  108 ,  112 . In such an aspect, the swing training device  100  may still bend or flex in response to an application of force or pressure from a user’s forearms  310  during use, such that the body  102  flexes, bends or otherwise deforms while the end regions  108 ,  112  remain fixedly coupled to one another via the attachment members  202 .
