TECHNICAL FIELD  
       [0001]    This invention relates to a lasso or lariat handling device and in particular a lasso handling device for holding and supporting a lasso for facilitating the capture of animals such as cattle and the capture of objects such as dock cleats for facilitating the connection of a boat mooring line to a mooring point. The present invention also relates to a rapid release mechanism for fast and accurate release of the lasso from the lasso handling device. 
       BACKGROUND ART  
       [0002]    Capture of animals and objects are often performed by the use of a lasso or lariat. The lasso or lariat comprises a rope with an eyelet at one end and the free end of the rope passes through the eyelet to form a loop. The lasso loop is free to contract in diameter once placed over the animal or object thus facilitating capture. 
         [0003]    There are devices for holding the lasso or lariat when placing the loop of the lasso or lariat over an animal or object to facilitate the capture of the animal or object. These devices used are slow in operation and inaccurate and when used for the capture of animals, failure can result in agitation of the animal resulting in difficulty of further capture. 
         [0004]    Lassoing is also used for purpose of capture of an object such as a dock cleat when mooring a boat where it is important that the boat is moored on the first attempt. Failure to capture the mooring point at the first attempt can result in damage to the boat and/or injury to the personnel attempting the mooring. 
         [0005]    Some devices have been proposed with the aim of overcoming the above disadvantages However in general these devices have not been particularly effective. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention aims to provide a lasso handling device which overcomes or alleviates the above disadvantages or which at least provides an alternative to the known lasso handling devices. Other objects and advantages of the invention will become apparent from the following description. 
         [0007]    The present invention thus provides in one preferred aspect, a lasso handling device for handling lassos of the type comprising an elongated rope having a looped end and a free end, said lasso handling device having first holding means for releasably holding a first portion of said rope within said looped end and second holding means spaced from said first holding means for releasable holding a second portion of said rope within said looped end to hold said looped end open for location over an animal or object. 
         [0008]    The term “rope” as used throughout the specification and claims includes any form of flexible line or rope and typically may comprise a multi-stranded rope such as a synthetic or natural rope having three or more strands or a braided rope. 
         [0009]    Preferably the respective holding means are configured such that the force required to release the rope from the first holding means is greater than the force required to release the rope from the second holding means. Preferably the holding means comprise resilient holding or gripping means and the resilient force applied in use by the first holding means is greater than the resilient force applied in use by the second holding means. 
         [0010]    Preferably the rope has an eyelet at one end and the lasso is defined by passing or threading a free or other end of the rope through the eyelet to form the looped end. The eyelet may be formed by splicing the rope. 
         [0011]    The rope may have an enlarged diameter portion within the looped end adapted to be gripped by the first holding means. The enlarged diameter portion may comprise an enlarged portion at the one end whereby the diameter of the rope is increased by the splicing of the rope to form the eyelet and/or the diameter of the rope may be increased at a selected point by circumscribing the rope at that point by a diameter build up material such as tape or Velcro to form an enlarged portion of the rope. The selected point on the rope at which the buildup material is placed can establish the size of the loop of the lasso defined by the looped end of the rope. 
         [0012]    The lasso handling device may be combined with or incorporated in an elongated tubular pole of wood, metal or other material having a free end and a handle end. The tubular pole can be of the extendable type. A rope gripping means comprising the first means for releasably holding a first portion of the rope may be located adjacent to the free end of the tubular pole. The rope gripping means may comprise a channel shaped clamping member adapted to resiliently grip the rope and suitably the enlarged portion of the rope. The channel shaped clamping member may be detachably secured to the pole. Preferably the channel shaped clamping member is screw engaged with the pole. The channel shaped clamping member may extend longitudinally of the pole and may further be angled to the pole to diverge outwardly there from rearward from the end of the pole. 
         [0013]    Preferably co operable coupling means are provided between the pole and the channel shaped member. The co operable coupling means allow for resistance of lateral movement of the channel shaped member relative to the pole 
         [0014]    The second releasable holding means is suitably spaced from the first releasable holding means longitudinally along the pole. The spacing of the second holding means from the first holding means may be selectively adjustable. Suitably the second holding means is slidable longitudinally of the pole to adjust the spacing from the first holding means. Preferably the second holding means when holding the second portion of the rope is locked or braked against substantial sliding movement along the pole. 
         [0015]    The second holding means may comprise an elongated arm or member adapted to resiliently clamp the rope against the pole. The arm or member may comprise a resilient hook which extends longitudinally of and substantially parallel to the pole and is spaced outwardly therefrom. 
         [0016]    The elongated arm or member is suitably connected to and extends from an adjustable sliding sleeve member. The adjustable sliding sleeve member is located coaxially relative to and circumscribes the pole and is positioned between the channel shaped clamping member and the handle end of the pole and can thus be moved longitudinally along the tubular pole for adjustment of the required size of the loop of the lasso. The resilient hook and the connected adjustable sliding sleeve can be made of either plastic or metal. 
         [0017]    The elongated arm or member is positioned on the tubular pole to face in an inward direction towards the channel shaped clamping member and defines an open mouth with the pole facing towards the channel shaped clamping member for receiving the rope and form a rapid release mechanism allowing a rapid release of the rope and lasso from the lasso handling device. Suitably the arm or member includes an indent to locate the rope. The arm or member may also include an enlarged jaw at its leading end extending towards the pole and forming the arm or member into a hook, the jaw restricting the entrance of the mouth to ensure that the rope when inserted into the mouth and past the jaw can be captured effectively between the member and pole. The resilient force applied by the arm or member may be due to resilience in the member or by a resilient connection of the arm or member to the sleeve member. 
         [0018]    Preferably, when the rope has an eye formed by a splice defining the enlarged portion, the enlarged portion in use is held and supported by the channel shaped clamping member with the eyelet positioned in a rearward direction from the clamping member towards the handle end of the pole. 
         [0019]    The rope of the lasso that passes outwards to the front of the channel shaped clamping member forms is passed through the eye to form a loop of the selected lasso size and the rope within the loop is held transversely to the tubular pole by the resilient hook. 
         [0020]    The rope when held by the resilient hook transversely against the side of the tubular pole functions as a brake and locks the adjustable sleeve member against the tubular pole preventing the adjustable sleeve member moving longitudinally along the tubular pole. The braking function ceases when the rope of the lasso is released from the jaw of hook. 
         [0021]    The rope is reeved into the hook in a manner to facilitate the rapid release of the lasso once the animal or object is caught. 
         [0022]    The rope is transversely held by the hook and from the held position by the hook, the free end of the rope passes through the eyelet opposite the side of the hook that supports the loop of the lasso. As the free end of the rope extends through the eyelet, the eyelet is thus supported adjacent to the hook. The free end of the rope then extends in use towards the handle end of the pole where it is held by the operator. 
         [0023]    A rapid release is facilitated by the contraction of the lasso around the captured animal or captured object and with the free end of the rope held firmly by the operator the rope pivots against the eyelet of the lasso causing a force that rapidly ejects the rope from between the hook and pole. 
         [0024]    The lasso rope diameter contracts around the captured animal or object and the lasso rope continues to be held by the channel shaped clamping member which has a rope holding force greater than that of the hook. 
         [0025]    Thus the channel shaped clamping member of the device may now be adapted to direct the loop defining portion of the lasso whereby the contracting loop may be manipulated to accurately locate around an animal or object 
         [0026]    When the defining portion of the lasso loop is accurately located around the caught animal or object. the operator sharply pulls the pole back and the lasso is released from the channel shaped clamping member when the rope portion of the lasso passes from the large spliced or taped diameter of the rope to a smaller diameter where it thus cannot be held and the lasso is then released around the caught animal or object. 
         [0027]    Many applications can be performed by this invention such as applications for marine rescue, construction rigging and boat mooring.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0044]    Referring to the drawings and firstly to Fig, 1  there is illustrated a lasso handling device  9  according to the present invention which typically comprises a device  9  adapted to handle lasso&#39;s of variable loop size with speed and accuracy, the device  9  including a tubular extended pole  10  which can be adjustable in length. The pole  10  has a free end  11  and a handle end  12 . Mounted on the tubular pole  10  adjacent to the free end  11  is a channel shaped clamping member or line gripper  13 . The clamping member  13  as shown more clearly in  FIG. 3  and  FIGS. 9 to 12  is resilient and comprises an elongated channel shaped member of part circular form in cross section and having a pair of opposite curved side flanges or jaws  14 . Inwardly directed teeth like ribs  15  are provided adjacent the free longitudinal edges of the flanges or jaws  14  and define a restricted entrance  16  into the interior  17  of the channel shaped member  13 . The leading end of the channel shaped member  13  is tapered. 
         [0045]    The channel shaped member  13  is provided with a mounting flange  18  on its topside, that is the side opposite the flanges or jaws  14  with the mounting flange  18  extending longitudinally of the channel shaped clamping member  13  and the mounting flange  18  and includes on one side a shallow recess  19  complimentary to the tube shape of the pole  10 . Spaced apertures  20  are provided in the mounting flange  18  and extend through to the “channel” side of the member  13  to accept screws  21  which may be driven into apertures in the tubular pole  10  to hold the flange  18  to the tubular pole  10 . 
         [0046]    A resilient hook  22  is connected to an adjustable sliding sleeve  23  as shown in  FIGS. 2 and 4  to  8  which circumscribes the tubular pole  10  between the channel shaped member  13  and the handle end  12 , the hook  22  being defined by an elongated member or arm  24  extending from the sleeve  23  and longitudinally of the pole  10  and terminating in an enlarged jaw  25  which extends towards the pole  10  and which defines with the pole  10  a restricted mouth for capturing the rope of the lasso as described below. The resilient hook  22  is shaped to accept ropes of various sizes in an indent section  26  formed in the member  24 . The resilience of the hook  22  is achieved by the length of the arm or member  24  and the resilient hook  22  can be constructed of any resilient material such as plastic or metal. The adjustable sliding sleeve  23  can be constructed of material such as plastic or metal. The resilient hook  22  and the adjustable sleeve  23  are attached and may be formed as a single component such as by an integral moulding or formed as separate joined components. 
         [0047]    The lasso handling device  9  is particularly suited to handling a rope  27  which has a loop  28  to define a lasso, the rope  27  being of the type having an eyelet  29  at one end defined by an end portion  30  of the rope  27  which is looped back on itself and secured such as by means of a splice  31  to a further portion of the rope  27  as shown in FIGS.  13 , 14 , 15 , 16  and  17 . The splice  31  which constitutes a transversely enlarged portion of the rope  27  can be engaged with the channel shaped member  13  by being pressed into the entrance  16  in the member  13  to cause the flanges or jaws  14  to be resiliently deflected and to be received in the interior  17  of the member  13  with the splice  31  being gripped resiliently by the flanges or jaws  14 . In the embodiment illustrated in  FIGS. 1 ,  13  and  14  the splice  31  is positioned to be resiliently gripped by the channel shaped clamping member  13  such that the eyelet  29  is positioned rearwardly of the channel shaped clamping member  13 . 
         [0048]    This configuration allows the free end of the rope  27  to be held by the resilient hook  22  transversely to the tubular pole  10 . For this purpose, the rope  27  is pushed past the jaw  25  of the resilient hook  22  and is held transversely in the indent section  26  formed in the arm  24  of the resilient hook  22 . The rope  27  is held by the arm or member  24  against the tubular pole  10  as shown in  FIG. 8  to form a braking action to prevent the adjustable sliding sleeve  23  moving longitudinally along the tubular pole  10  until the rope  27  is released from the jaw  22 . 
         [0049]    The free end of the rope  27  passes across the indent section  26  of the resilient hook  22  and through the eyelet  29  to form the loop  28 . The free end of the rope  27  passes back to the handle end  12  of the tubular pole  10  and is held by the operator  33 . 
         [0050]    The fast release of the rope  27  from the resilient hook  22  is facilitated by the contraction of the lasso loop  28  around the caught object  34  as shown in  FIGS. 15 and 16 . The free end of the rope  27  held firmly by the operator  33  effectively causes the rope  27  to pivot around the fixed point of the eyelet  29  creating a force exceeding the force required by the resilient hook  22  to hold the rope  27  and the rope is thus forcibly ejected from the resilient hook  22  in the direction D. 
         [0051]    Release of the rope  27  with the splice  31  from the channel shaped clamp  13  is affected by the operator  33  sharply pulling the tubular pole  10  back in the direction A as Illustrated in  FIG. 17 . The channel shaped clamp moves from the large diameter splice  31  to the smaller diameter of the rope  27  which cannot be held leaving the released lasso loop  28  around the caught animal or object  34 . 
         [0052]    Referring to  FIGS. 18 and 19  the lasso size can be adjusted by the movement of the adjustable sleeve  23  in direction B along the pole  10  to lessen the lasso size as illustrated in  FIG. 18  and in direction C to increase the lassos size as illustrated in  FIG. 19 . 
         [0053]      FIG. 19  illustrates an enlarged lasso loop  28  held and supported by the channel shaped clamping member  13  and the resilient hook  22 . The rope  27  held by the channel shaped clamping member  13  has an increased diameter, increased by diameter build up material such as tape or Velcro  35  as illustrated in  FIG. 20 . Release of the rope  27  is similar to that as described above with reference to  FIG. 17  within in this case release of the diameter build material  35  from the channel shaped clamping member  13  being affected by the operator  33  pulling the tubular pole  10  back in the direction A. The channel shaped clamping member  13  moves from the large diameter  35  to the smaller diameter of the rope  27  and cannot be held leaving the released lasso loop  28  around the caught animal or object  34 . 
         [0054]    It will be appreciated that the channel shaped clamping member  13  and the resilient hook  22  may be varied in size to suit various sized lasso ropes  27  with which the lasso handing device  9  is to be used. Furthermore, the clamping member  13  and hook  22  may be of various different configurations and designs. Whilst the resilience of the resilient hook  22  may be due to the inherent resilient in the arm  24  of the hook  22 , the arm  24  alternatively may be relatively rigid and joined to the sleeve member  23  through a resilient connection, for example via a spring loaded pivot or through are resilient plastics connection. 
         [0055]    The use of the term “comprising” or derivatives thereof as used throughout the specification and claims are taken to specify the presence of the stated features, integers and components referred to but not preclude the presence or addition of one or more other feature/s, integer/s, component/s or group thereof. 
         [0056]    Whilst the above has been given by way of illustrative embodiment of the invention, all such variations and modifications thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of the invention as defined in the appended claims.
