the collapsible tactile support of the present invention solves the problems in the prior art through the provision of a flexible or collapsible support member incorporated into a suitable attachment means . it is contemplated that the attachment means of the present invention can be easily configured for any joint and / or use , such as a golf trainer , and further that the collapsible support member can be constructed with varying degrees of strength resistance . it is further contemplated that support members of varying resistance will be fully interchangeable in the attachment means , thereby accommodating the specific needs of the individual user . thus , the present invention provides a collapsible joint support that can be universally configured and utilized as needed for a particular joint and sport . in a preferred embodiment , the collapsible joint support is configured as a golf training device . in a particularly preferred embodiment , the present invention provides a collapsible wrist support designed to releasably maintain the leading wrist of a golfer in a coplanar alignment with the back of the forearm during the backswing and follow - through of a golf club . as is evident from a review of the drawings and the detailed description provided below , this preferred embodiment represents a considerable improvement over prior art training aids , including devices such as that described in u . s . pat . no . 5 , 499 , 820 . the &# 39 ; 820 patent , although discussing the need to accommodate some movement in the following wrist during a golf swing , provides a largely ineffective configuration consisting of a substantially rigid brace attached to the wrist via a stretchable , resilient material . unfortunately , the brace is also attached to both the forearm and the index finger with additional , non - resilient straps , creating at best a very limited and awkward up and down movement of the wrist at the substantial expense of comfort . in contrast , the collapsible support of the present invention provides for free movement of the wrist or other joint once a predetermined threshold force or pressure is applied sufficient to collapse the support member . thus , the present invention releasably supports the joint in a corrective manner and provides tactile biofeedback to the user regarding the movement and position of the joint up to the desired threshold level , at which point the wrist or other joint is tactually released for free movement . referring to fig1 the collapsible tactile support of the present invention comprises a collapsible support member ( 10 ) incorporated into a suitable means for positioning ( 20 ) the support member to support a joint . in the preferred embodiment shown in fig1 the means for positioning ( 20 ) comprises at least one measurably adjustable strap ( 22 ) for securing the support member ( 10 ) over the bending point of the wrist or other joint . it is contemplated that the strap ( 22 ) can be advantageously made of nylon with a conventional tightening means such as an adjustable clip , or alternatively a velcro ™ tab and closure mechanism . the strap ( 22 ) may be made measurably adjustable through any number of conventional means , such as suitable markings on the strap ( 22 ), to allow the user to measurably adjust the fit of the support member ( 10 ) and easily refasten at the desired level of tension . it is further contemplated that the strap ( 22 ) may be padded in a conventional fashion for the comfort of the user . in an alternative embodiment , the means for positioning ( 20 ) the collapsible wrist support of the present invention further comprises a thumb retention harness ( 24 ) and / or a finger retention harness ( 26 ) for maintaining the proper positioning of the support member ( 10 ). it is contemplated that both retention harnesses can be advantageously constructed from either a substantially rigid material such as nylon cord , or alternatively a more elastic material such as rubber , and attached to the collapsible wrist support in a variety of ways . in the preferred embodiment shown in fig1 the thumb retention harness ( 24 ) is attached to the strap ( 22 ), while the finger retention harness ( 26 ) is attached to the support member ( 10 ). it is further contemplated that either or both of these additional harnesses can be incorporated into the collapsible support of the present invention to more securely position the support member ( 10 ) on the wrist , as well as to enable its use with a conventional golf glove . as shown in fig1 in one embodiment the collapsible support member ( 10 ) of the present invention further comprises a support strip ( 14 ) enclosed within a cover ( 16 ) comprising , in one embodiment , a fabric material . it is also contemplated that additional padding material ( not shown ) can be interposed between the support strip ( 14 ) and the cover ( 16 ), for the comfort of the user . in an alternative embodiment , a block ( not shown ), such as a soft to semi - rigid elastic material such as rubber , can be placed between the wrist joint and support member ( 10 ) to control the degree of allowed wrist bend . alternatively , the user can measurably adjust the strap ( 22 ) to provide varying degrees of allowed wrist bend prior to engagement of the wrist with the support member ( 10 ). as can readily be recognized , tightening the support member ( 10 ) flush against the wrist will immediately engage the support member and releasably restrain any wrist movement . conversely , loosening the strap or placing the block between the wrist joint and support member distances the support member ( 10 ) from the wrist , thereby allowing a limited amount of wrist movement prior to engagement by the support member ( 10 ). thus , more experienced golfers who prefer a small amount of wrist movement during the backswing and follow - through can measurably adjust the strap ( 22 ) or insert a block to control the amount of wrist movement . in a particularly preferred embodiment described more fully below , the resistive or corrective tension of the support member ( 10 ) is further adjusted by variations in the collapse threshold of the support strip ( 14 ) itself . the support strip ( 14 ) comprises a generally rectangular strip of semi - rigid material such as , for example , spring steel , configured so as to &# 34 ; collapse &# 34 ; or bend at a point anywhere along the strip but always at that portion over the joint , and return to its original configuration when the collapsing pressure is removed . in the preferred embodiment illustrated in fig2 the support strip ( 14 ) is slightly curved around a longitudinal axis , and is approximately 2 - 6 inches in length , 0 . 5 to 1 . 5 inches in width , and 0 . 003 to 0 . 005 inches thick . in a particularly preferred embodiment configured for most users , the support strip ( 14 ) is composed of spring steel with dimensions of 4 inches in length , 0 . 7 inches and slightly curved in width ( 0 . 75 flattened ), and 0 . 004 inches thick . of course , many alternative geometrical configurations and dimensions of the support strip ( 14 ) can easily be made depending upon the particular joint to be supported ( see , e . g ., fig4 & amp ; 5 ) and the level of resistive or corrective support desired . for instance , an increase in the thickness , curvature or length of the support strip ( 14 ) will proportionately increase the &# 34 ; collapse threshold ,&# 34 ; or the level of resistance in the collapsible support member ( 10 ), thereby providing more corrective support for the user and increasing the amount of pressure required to &# 34 ; collapse &# 34 ; or bend the support member ( 10 ). thus , the resistance of the present invention can be varied to accommodate the skill level of the users by providing different support strips . by way of example , therefore , a beginning golfer may wish to select a support strip ( 14 ) having a relatively high resistance to bending ( i . e . a high &# 34 ; collapse threshold &# 34 ;), while a more experienced golfer may desire a support strip ( 14 ) having a much lower resistance ( i . e . a low &# 34 ; collapse threshold &# 34 ;). such alternative embodiments of the support strip ( 14 ) are fully considered to be within the spirit and scope of the present invention . referring now to fig3 in an alternative embodiment the collapsible support member ( 10 ) of the present invention is incorporated into a slip pocket ( 30 ) sewn into a conventional golf glove ( 32 ). in a particularly preferred embodiment , the slip pocket ( 30 ) further incorporates a tightening means ( 34 ) such as a tension - adjustable snap or , alternatively , a built - in strap controlled by a tension - adjustable velcro ™ tab . the slip pocket ( 30 ) is positioned in the glove ( 32 ) such that the collapsible support member ( 10 ) is positioned over the back of the user &# 39 ; s wrist where the hand bends at the forearm . with this embodiment it is contemplated that support strips ( 14 ) of varying resistance levels as described above can easily be removed and replaced in the slip pocket ( 30 ) of the glove ( 32 ), so that a user can adjust the level of corrective support according to his or her own individual wrist strength and skill level . in addition , the tension can be adjusted via tightening means ( 34 ) to allow for limited wrist movement prior to engagement by the support member , as described previously . by way of example , to use a device of this embodiment the user first inserts his or her hand into glove ( 32 ). the user then selects the support strip ( 14 ) providing the desired predetermined support and slides it into pocket ( 30 ), and tightens the glove and support member ( 10 ) to the desired tension against the wrist . when the wrist is maintained at the proper position , the support remains in its original position . if the user attempts to flex his or her wrist , but does not exert enough pressure against the support member ( 10 ) to overcome the collapse threshold , the support member ( 10 ) will aid in maintaining the correct position of the wrist . if the collapse threshold is exceeded by the continuous pressure exerted by the user , the support member ( 10 ) will collapse , delivering a tactile signal to the user to permit them to correct their wrist position . when the user &# 39 ; s wrist is returned to the correct position , the support member ( 10 ) automatically snaps back ( returns ) to its original position supporting the wrist . thus , when used as a golf training aid , this device assists in training the golfer to position the wrist correctly throughout the entire swing ; that is , to keep the wrist flat ( or coplanar ) relative to the back of the forearm during the backswing and downswing , and then subsequently &# 34 ; break &# 34 ; their wrist ( i . e . receive the tactile signal from the present invention ) well after ball contact at the end of the follow - through . it is further contemplated that in an alternative embodiment the collapsible wrist support of the present invention can deliver an audible signal in addition to the tactile signal . another advantageous use of the present invention for golf training purposes is the positioning of the support member ( 10 ) on the inside or outside of a golfer &# 39 ; s ankle , to provide corrective support and tactile biofeedback to prevent the golfer from leaning or &# 34 ; falling &# 34 ; away from the desired direction of the ball flight during the backswing . the golfer &# 39 ; s ankle typically bends outward in response to this leaning motion , which all too often results in either &# 34 ; topping &# 34 ; the ball or hitting the ball &# 34 ; fat &# 34 ;( i . e . striking the ground before striking the ball ), since the club head is substantially displaced behind the ball at the bottom of the downswing . thus , the present invention can also be used to provide corrective support to prevent the bending of the golfer &# 39 ; s ankle ( typically the right ankle on a right - handed golfer and vice versa ), in a manner very similar to the corrective support of the wrist described above . the collapsible tactile support of the present invention may also find advantageous use for the therapeutic support and rehabilitation of injured joints . in one embodiment illustrated in fig4 one support member ( 10 ) is positioned to releasably support a strained middle finger using , for example , velcrot ™ straps as positioning means ( 20 ). fig4 also illustrates an alternative embodiment of the wrist support of the present invention , having two support members ( 10 ) positioned on either side of the wrist again via velcro ™ straps , to provide collapsible support for a strained wrist . as noted previously , the present invention also contemplates using support members ( 10 ) of various dimensions to provide therapeutic support for different joints , such as , for example , the collapsible support member ( 10 ) and positioning means ( 20 ) for the knee joint illustrated in fig5 . the collapsible tactile support of the present invention is particularly useful for therapeutic purposes , since it can provide support for the injured joint while at the same time allowing for rehabilitative movement in the joint without any need to remove the support itself . in fact , the ability of the present invention to return to its original configuration when the collapsing pressure is removed actually aids in the therapeutic movement . thus , an outside force or pressure can be applied ( i . e . by the non - injured hand ) to the injured joint in excess of the collapse threshold of the support member ( 10 ), in order to bend the support member ( 10 ) and allow for rehabilitative movement in the joint itself . then , when the outside force is removed the injured joint is returned to its original supported condition via the return action of the support member ( 10 ). the present invention has been described in terms of the preferred embodiment . one skilled in the art will recognize that it would be possible to construct the elements of the present invention from a variety of materials and to modify the placement of the components in a variety of ways . while the preferred embodiments have been described in detail and shown in the accompanying drawings , it will be evident that various further modifications are possible without departing from the scope of the invention as set forth in the following claims .
the present invention provides a collapsible tactile joint support for therapeutic use or as a training aid for sports . the collapsible tactile joint support of the present invention provides corrective tension for the joint up to a predetermined threshold level that is reached by applying an internal or external force , at which point the joint support bends or collapses thereby releasing the corrective tension and freeing movement in the joint . a collapsible tactile wrist support for use as a golf training aid is also described .
