Abstract:
A hookless coupling device for releasable connection to a sports harness includes an elongate body having a connector end for connection with the sports harness, an engagement end, and an elongate aperture extending between the connector end and the engagement end for engaging an engager. The aperture is wider at the connector end than at the engagement end. The sports harness includes a band for surrounding the waist or hips of a person, and the elongate body. A sports device, releasably engagable to the harness, has a spherical engager tethered with a line. The aperture passes the spherical engager though the engagement end and the engager is moved to the connector end. A sports kite includes a canopy, a traction line having a first end tethered to the canopy, and a second end to which the spherical engager is connected.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a coupling device for a sports harness. The invention also relates to a sports harness with engagement and engager means for releasably coupling a sports device to the harness. 
       BACKGROUND TO THE INVENTION 
       [0002]    In wind driven sports such as kiteboarding, windsurfing and sailing a sportsperson wears a harness to which the sports device can be releasably coupled. The harness includes a spreader bar with a downwardly orientated hook. The sports device also includes a loop on a tether, or line, which can be engaged with the hook to releasably couple the sports device to the harness. The pull of the sports device on the hook and harness is generally in an upwards direction and outwards, for example in kiteboarding the kite is often manoeuvred overhead of the rider. The hook must have a downward orientation in order to retain the loop. However, the upwards pull of the sports device can cause rotation of the spreader bar and front of the harness causing discomfort to the sportsperson. 
         [0003]    Wind driven sports utilising a harness coupling arrangement are most frequently performed on water and involve a sports device having a number of lines. An additional disadvantage of the tradition hook and hoop coupling arrangement is the risk of lines unintentionally catching or tangling with the hook and posing a danger to the sportsperson. 
         [0004]    It is an object of the present invention to overcome or at least ameliorate these disadvantages with traditional hook and loop coupling of wind drive sports devices.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0028]    The following description is given by way of example only to illustrate the invention and is not intended to limit the scope of use or functionality of the invention. In particular, the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the accompanying drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used is for the purpose of description and should not be regarded as limiting. 
         [0029]    In the description and claims the term “hookless” means not having or utilising a hook as one element in a coupling means (i.e., a hook and loop as is currently known in wind driven sports such as kiteboarding, windsurfing and sailing). The terms “inwardly”, “towards”, “upwardly” and “away from”, “outwardly”, “up” and “down” are to be interpreted with reference to the in-use, in-situ or operational placement of a device, body or object in relation to a sportsperson using said device or body or object in a normal standing or operating posture. 
         [0030]      FIG. 1  illustrates a general kite surfing set-up in which a rider or kite surfer  4  riding a waters sports board utilises a large transition kite  2  to pull the rider and board across the surface of a body of water. The rider wears a harness  3  to which a traction line  10  of the kite can be releasably coupled. The invention provides a hookless coupling device for releasably securing the kite  2  to the rider&#39;s harness  3 . In its broadest embodiment the hookless coupling device is an elongate body  5  that can be connected at one end  6 ,  11  to a sports harness  3  and has an opposite engagement end  7  to which the sports device  2  releasable couples by way of an engager  8  connected to the sports device traction line  10 . The body  5  has an elongate aperture  9  that preferably extends substantially the length of the body  5  between the harness connector end  6  and the engagement end  7 . The aperture is wider in breadth at the harness connector end  6  to allow the engager  8  to pass through the aperture  9 . The aperture  9  narrows towards the engagement end  7  such that the engager  8  cannot pass though the aperture  9  at the engagement end  7 . In use the elongate body  5  extends upwardly and away from the harness  3  and sportsperson  4  wearing the harness  3 . The engager  8 , which is tethered to the sports device  2  by the traction line  10  (or rope in non-nautical terms), is passed through the wider end  11  of the aperture  9  and moved towards the engagement end  7  where it cannot pass back though the aperture  9  and therefore engages with the engagement end  7  of the body  5  to couple the tethered sports device  2  to the body  5  and the harness  3 . In the most preferred embodiment the engager  8  is a spherical shaped body, or ball, and the body  5  has a semi-circular or cup-shaped socket  12  at the engagement end  7  communicating with the aperture  9  so that when a spherical engager  8  is moved to the engagement end  7  it is received within the socket  12  to pivotally engage the body  5  and engager  8  in the manner of a ball and socket joint. 
         [0031]      FIGS. 2 and 3  illustrate how the engager  8  and hookless coupling device  5  are coupled and uncoupled. To couple the kite  2  the rider  3  moves the engager  8  tethered to the kite line  10  from a low position in an inwardly direction, as indicated by arrow A, and then upwardly in the direction, as indicated by arrow B, so that the engager  8  passes through the wider end  11  of the hookless coupling device slot. The engager once through wider end  11  of the slot is moved upwardly and away from the rider to secure it with the engagement end  7  of the hookless coupling device. Generally in normal use the pull direction of the tethered sports device  2  is upwardly and away from the sportsperson  3  operating the sports device  2 . The pull of the sports device  2  is thus from the wider harness connector end  6  towards the engagement end  7  and assists in moving and holding the engager  8  into the engaged position at the engagement end  7  of the body  5 . In order to uncouple the tethered sports device  2  from the riders harness the rider must move the engager  8  in the opposite direction of the pull, which is inwardly towards the rides body, as indicated by arrow C, and then downwardly, as indicated by arrow D, though the wider end  11  of the aperture  9 . 
         [0032]    In one embodiment the elongate body  5  is connected with the sports harness  3  by way of a spreader bar  13 . The spreader bar  13  is affixed at the connector end  6  of the elongate body  5 . The spreader bar  13  is orthogonal to the elongate body  5  which is affixed at the centre of the bar  13 . At either end of the spreader bar  13  there are buckles or other means  14  for attaching the spreader bar  13  with straps of a sports harness  3  in known manner. In other embodiments the elongate body  5  is connected with the sports harness  3  by means other than a spreader bar. For example, in one alternative embodiment the elongate body  5  may have a buckle at its connector end  6  for attachment directly to a strap of the sports harness  3 . It is preferable, although not essential, that the elongate body  5  be held in a position upwardly and away from the harness  3  when not engaged with the engager  8  of the sports device  2  so that the engager  8  may be easily engaged with the aperture  9  of the elongate body  5  quickly and with one hand. The spreader bar  13  maintains the elongate body  5  in this ready orientation. In an alternative embodiments using for example a buckle and strap to attach the elongate body  5  to the harness  3 , a pocket or strap/flap on the harness or plastic fitting can be used to maintain the elongate body in an upwardly and outwardly orientation. 
         [0033]    In one embodiment, for example shown in  FIGS. 2, 3 and 16 , the elongate body  5  and aperture  9  are formed by a frame of stiff wire bent in a narrow inverted U-shape. The free tail ends  6  of the two legs  15 ,  16  of the U are affixed to the centre section of the spreader bar  13  by welding for example. The two legs  15 ,  16  form two sides of the frame defining opposite elongate edges of the aperture  9 . The top of the U forms a curved end  7  joining the sides at the engagement end of the elongate body. The two legs  15 ,  16  forming two sides of the frame may not be parallel, but diverge towards the tail ends attached to the spreader bar to provide a wider slot  11  at the connector end  6  for the engager  8  to pass through. Alternatively, and perhaps preferably, the two legs  15 ,  16  forming two sides of the frame may have outwardly bent dog-legs to provide a wider slot  11  at the connector end  6  for the engager  8  to pass through. The curved end  7  of the U may also be bent slightly upwardly about an axis transverse to the slot  9 ,  11  at the engagement end  7  to form a semi-circular socket  12  for pivotally receiving a ball shaped engager  8 . 
         [0034]      FIGS. 5 through 7  show an alternative embodiment of the hookless coupling device  5  that may be connected directly to a sports harness  3  by a buckle or other means as aforementioned. In such an embodiment the device  5  has the same configuration as other embodiments from the engagement end  7  to the wider slot  11  at the connector end  6  for the engager  8  to pass through. In this embodiment the connector ends  6  of the body are closed by a transverse leg  17  that closes-the-loop on the elongate slot  9 ,  11 . A strap and buckle or other such coupling means can engage with the transverse leg  17  to secure the hookless coupling device  5  directly to the harness without a spreader bar  13 . Alternatively such a hookless coupling device  5  can also be removably connected with a spreader bar  13  in a flexible manner as illustrated in  FIGS. 8 through 11 .  FIGS. 8 and 9  illustrate a plastic or elastic body  18  for connecting the hookless coupling device  5  with the spreader bar  13 . The connecting body  18  has a first aperture  19  mounded for otherwise formed about the distal transverse leg  17  of the hookless coupling device  5 . A second C-shaped aperture  20  is provide parallel to the first aperture  19  and has an open edge to allow the centre region on the spreader bar  13  to be introduced into the second aperture  20 . A securing cord or spring clip  21  is provided and engageable with a catch  22  for closing the open edge of the second aperture  20  thereby flexibly and releasably connecting the hookless coupling device  5  to the spreader bar. As an alternative arrangement shown in  FIGS. 10 and 11  a webbing strap is used to secure the hookless coupling device  5  to the spreader bar. A webbing loop is secured to or around the distal transverse leg  17  of the hookless coupling device  5  at its first end  23 . The middle  24  of the loop is passed abound the central region of the spreader bar  13  and hookless coupling device  5  passed through the distal end  25  of the webbing loop to secure the loop and hookless coupling device  5  to the spreader bar in a flexible and releasable manner. 
         [0035]    In some situation, such as training for example, it is preferable to secure that ball engager  8  with the hookless coupling device  5  so that it cannot become uncoupled inadvertently.  FIGS. 12 through 16  show an arrangement of the hookless coupling device  5  with a securing gate  30  that can be closed to secure the ball engager  8  with the hookless coupling device  5 . In this embodiment a pair of tabs  29  are attached to respective side legs  15 ,  16  of the body  5  adjacent the narrower at the engagement end  7 . A U-shaped gate  30  is pivotally secured to respective ones of the tabs  29  by its two open ends  27   28 . The shape of the U-shaped gate  30  and position of the tabs  29  is such that the gate  30  follows closely the engagement end  7  of the body, and when moved to the secured position as discussed below, the gate can pass about the ball engager  8  and interfere with the wider end  11  of the slot. In a first, non-securing position, as shown in  FIG. 13 , the gate is positioned to lie against the engagement end  7  of the body  5 . The ball engager  8  can be coupled with the hookless coupling device  5  as aforementioned. TO secure the ball engager with the hookless coupling device  5  the user manually flips, or pivots, the gate  30  to a second position, as shown in  FIG. 14 , such that the gate  30  passes around the ball engager  8  and interferes with the wider end  11  of the slot.  FIG. 15  illustrates that with the gate  30  to a second securing position the ball cannot be moved in the downwardly direction of arrow D through the wider end  11  of the slot as required to uncouple the ball engager  8  and hookless coupling device  5 . The gate  30  interferes with the ball  30  and line  10  preventing the ball  30  from passing though the wider end  11  of the slot. To uncouple the ball engager  8  and hookless coupling device  5  the rider must flip, or pivot, the gate  30  back to a first position, as shown in  FIG. 13 . 
         [0036]    Although the preferred embodiment of the invention is a coupling device, the invention may be embodied as or sold coupled to or in conjunction with one or more of the engager, a spreader bar, a sports harness or a sports kite in part or complete. The preferred embodiment of the coupling device is described or illustrated for use in kite surfing. However, the skilled addressee with appreciate that the coupling device will find equal and equivalent application in other sports requiring a rider or user to be selectively coupled to sports equipment via a body harness. Such alternative examples include but are not limited to wind surfing and sailing trapeze.
