Abstract:
A tote for dragging a game carcass has first and second identically configured rigid members that are movable toward each other to bring each of two side-by-side recesses defined by one of the members into alignment with a different one of the recesses defined by the other of the members when the members are urged toward engagement. An alignment assisting projection carried by the one member is extensible into an opening defined by the other member. The recesses are preferably substantially semi-circular and sized to close about and grasp small regions of front or rear legs of a game carcass. A flexible tow rope or cable extends through aligned passages of the rigid members and connects with a handle. Pulling the tow rope or cable can help clamp the rigid members together.

     BACKGROUND 
     When hunters shoot relatively heavy four-legged game such as deer, the need to move downed carcasses from one place to another can present a daunting problem. Such game is often taken in a remote area and must be transported to another location where vehicular transportation is available, or where the game is to be dressed. Proposals have been forthcoming for many years for various types of devices intended to assist with the transport of game carcasses from a remote location where game was downed to another location more convenient for vehicular transport or for processing. 
     In many instances, the preferred mode of transport from a remote area is to drag a carcass by use of a game drag device of some sort that is connected to the front or rear legs, or some other body portion of the carcass. The use of a drag device has been preferred over the alternative of simply tying a tow rope or cable to the carcass, for ropes or cables frequently come loose when a carcass becomes mired in wet or muddy ground, or becomes caught or snagged at some other location where retying the rope or cable may present difficulties. 
     One prior proposal of a tote for gripping leg portions of, and for towing a taken game carcass, is shown in the drawings of U.S. Pat. No. 4,243,164 issued Jan. 6, 1981 to Burlison et al, the disclosure of which patent is incorporated herein by reference. 
     SUMMARY 
     The present invention addresses the need to drag a heavy taken game carcass by providing a small, lightweight, preferably pocket sized tote having two rigid members that are designed to be clamped securely toward each other to receive, retain and grip therebetween small leg or ankle regions of a taken game carcass so the carcass can be dragged securely from one location to another by pulling on a handle of a flexible tow rope or cable that extends through aligned passages of the two rigid members which cooperate to form a main body of the tote. 
     In preferred practice, the two rigid members are of identical configuration, and the flexible tow rope or cable connects with the two rigid members in a way that clamps the members toward each other when one pulls on a handle connected to the flexible tow rope or cable. 
     In a preferred manifestation or embodiment of the tote, when the two rigid members are clamped toward each other, the recesses of one member cooperate with the recesses of the other member to receive, to grip therebetween, and to releasably retain relatively small leg or ankle portions of a taken animal carcass, thereby enabling a flexible tow rope or cable connected to the rigid members of the tote to be pulled or towed to drag the carcass from one location to another. 
     As used herein, the term “ankle” refers to a small or narrowed front or rear leg region of diminished size located a short distance above a hoof of a taken game carcass—a leg region that is suitable to be received in and retained by such cooperative recesses as are provided by the two rigid clamp-together members that are described herein as forming the main body of a tote that incorporates features of the present invention. 
     In a preferred manifestation or embodiment of the invention, a flexible tow rope or tow cable extends through aligned passages defined by the two rigid members that form the main body of a tote. An end region of the tow rope or cable is knotted or otherwise provided with an enlargement that cannot move through the aligned passages. If desired, a commercially purchased gripping device may be installed on the tow rope or cable to aid in holding the rigid members in a clamped-together position when towing force applied to the tow rope or cable is relieved. 
     In a preferred manifestation or embodiment of the invention, the flexibility of such portions of the tow rope or cable as may extend between the two rigid members when the members are significantly spaced apart permits the two rigid members to be turned at least a quarter turn relative to each other, which renders it easier to insert narrow ankle portions of the legs of a taken game carcass into the recesses of the rigid members before the rigid members are aligned and clamped together to grip and retain the ankle portions.

     DETAILED DESCRIPTION 
     Referring to  FIGS. 1 and 2 , one preferred form of a tote for use in dragging a taken game carcass from one location to another is indicated generally by the numeral  100 . A main body of the tote  100  includes first and second rigid members  110 ,  120  that are formed from a material selected to be stiff, rigid, strong and resistant to sunlight and inclement weather. 
     Second and third preferred forms of totes that embody features of the present invention are shown in  FIGS. 3-4 and 5-6  that utilize pairs of rigid members  210 ,  220  and  310 ,  320 , respectively. While the rigid members  110 ,  120  and  210 ,  220  and  310 ,  320  may, of course, be constructed of metal, it is preferred that they are formed from injection-molded plastics material that cooperate to provide tote bodies that are relatively light in weight and that can fit in reasonably small spaces such as one&#39;s pocket while still being capable of serving as the bodies of totes that are well suited for use with game carcasses of at least the size of deer without deforming or breaking during rugged use. 
     The rigid members  110 ,  120  of the first embodiment  100  are preferably of similar, if not completely identical, configuration. In preferred practice, the rigid members  110 ,  120  define what will be referred to as top and bottom surfaces  111 ,  121 , respectively, of the body of the first embodiment  100 . The rigid members  110 ,  120  also define surfaces  112 ,  122 , respectively, that face toward each other. The surfaces  112 ,  122  have flat portions  114 ,  124 , respectively, that are intended to extend parallel to each other, and have curved portions  116 ,  126  and  118 ,  128 , respectively, that define recesses  118 ,  128 , respectively, that are of generally U-shape, C-shape, or semi-circular shape. 
     The rigid members  210 ,  220  of the second embodiment  200  are preferably of similar, if not completely identical, configuration. In preferred practice, the rigid members  210 ,  220  define what will be referred to as top and bottom surfaces  211 ,  221 , respectively, of the body of the second embodiment  200 . The rigid members  210 ,  220  also define surfaces  212 ,  222 , respectively, that face toward each other. The surfaces  212 ,  222  have flat portions  214 ,  224 , respectively, that are intended to extend parallel to each other, and have curved portions  216 ,  226  that define recesses  218 ,  228 , respectively, that are of generally U-shape, C-shape, or semi-circular shape. 
     The rigid members  310 ,  320  of the third embodiment  300  are preferably of similar, if not completely identical, configuration. In preferred practice, the rigid members  310 ,  320  define what will be referred to as top and bottom surfaces  311 ,  321 , respectively, of the body of the third embodiment  300 . The rigid members  310 ,  320  also define surfaces  312 ,  322 , respectively, that face toward each other. The surfaces  312 ,  322  have flat portions  314 ,  324 , respectively, that are intended to extend parallel to each other, and have curved portions  316 ,  326  that define recesses  318 ,  328 , respectively, that are of generally U-shape, C-shape, or semi-circular shape. 
     When the rigid members  110 ,  120  of the first embodiment  100  are moved toward each other in directions indicated by arrows  107  in  FIGS. 1 and 2 , the linear surface portions  114 ,  124  may be caused to clampingly engage. As is shown in  FIGS. 1 and 2 , the arrows  107  extend perpendicular to the flat surface portions  114 ,  124  at a time when the flat surface portions  114 ,  124  extend parallel to each other. 
     When the rigid members  210 ,  220  are moved toward each other in directions indicated by arrows  207  in FIGS.  3  and  4 , the flat surface portions  214 ,  224  may be caused to clampingly engage. As depicted in  FIGS. 3 and 4 , the arrows  207  extend perpendicular to the flat surface portions  214 ,  224  at a time when the linear surface portions  214 ,  224  extend parallel to each other. 
     When the rigid members  310 ,  320  are moved toward each other in directions indicated by arrows  307  in  FIGS. 5 and 6 , the flat surface portions  314 ,  324  may be caused to clampingly engage. As is shown in  FIGS. 5 and 6 , the arrows  307  extend perpendicular to the flat surface portions  314 ,  324  at a time when the linear surface portions  314 ,  324  extend parallel to each other. 
     As can best be seen in  FIG. 1 , the identical rigid members  110 ,  120  are each provided with one generally cylindrical projection  105 , and with one generally cylindrical opening  106  sized to receive the projection  105  that extends from the other of the members  110 ,  120 . As the members  110 ,  120  are moved toward and draw near to each other, each of the projections  105  is received in one of the openings  106  to assist in maintaining the members  110 ,  120  in proper alignment with each other as they are clamped together. 
     As can best be seen in  FIG. 3 , the rigid members  210 ,  220  are each connected by threaded fasteners  290  that extend through aligned passages  235  to maintain alignment between the members  210 ,  220 , and to hold the flat surface portions  214 ,  224  in substantially parallel relationship as the members  210 ,  220  are clamped together. The threaded fasteners  290  have enlarged heads  292  at their lower end regions that engage the surface  221 , and have wing nuts  294  that are threaded onto upper end regions of the fasteners  290  which engage the surface  211  and can be tightened to clamp the members  210 ,  220  toward each other. 
     As can best be seen in  FIG. 5 , the rigid members  310 ,  320  are each provided with one generally rectangular projection  305 , and with one generally rectangular opening  306  that is sized to receive the projection  305  that extends from the other of the members  310 ,  320 . As the members  310 ,  320  are moved toward and draw near to each other, each of the projections  305  is received in one of the openings  306  to assist in maintaining the members  310 ,  320  in proper alignment with each other as they are clamped together. 
     The members  110 ,  120  of the first embodiment  100  have centrally located passages  115 ,  125 , respectively, that are shown by hidden lines in  FIG. 1 . A flexible tow rope or cable  160  is threaded loosely through the passages  115 ,  125 . A knot  162  or other enlargement-defining element such as a crimped-on member (not shown) that is too large to enter the passage  125  is provided on a portion of the tow rope or cable  160  that extends beyond the lower surface  121  of the rigid member  120 . 
     The members  210 ,  220  of the second embodiment  200  have centrally located passages  215 ,  225 , respectively that are shown by hidden lines in  FIG. 3 . A flexible tow rope or cable  260  is threaded loosely through the passages  215 ,  225 . A knot  262  or other enlargement-defining element such as a crimped-on member (not shown) that is too large to enter the passage  225  is provided on a portion of the tow rope or cable  260  that extends beyond the lower surface  221  of the rigid member  220 . 
     Referring to  FIG. 5 , the members  310 ,  320  of the third embodiment  300  define two sets of spaced apart yet generally centrally located aligned passages  315 ,  325  and  317 ,  327 , respectively. A flexible tow rope or cable  360  is threaded loosely downwardly through the passages  315 ,  325 , then through a cross-passage  329  that extends transversely between the passages  325 ,  327 , then upwardly through the passages  327 ,  317 . A knot  362  or other form of enlargement such as a crimped-on member (not shown) that is too sizable to enter the passage  317  is provided on an end region of the tow rope or cable  360  that resides in an upper end region of the passage  317  and extends part way into a cross-passage  319  that extends transversely between the passages  315  and  317 . 
     When the two rigid members  110 ,  120  of the first embodiment are sufficiently separated from each other (for example, as is shown in  FIGS. 1 and 2 ) so the generally cylindrical projections  105  do not extend into the generally cylindrical openings  106 , the rigid members  110 ,  120  are free to turn relative to each other about an axis of the aligned passages  115 ,  125  and of the tow rope or cable  160 —which turning capability can assist during efforts to insert narrow ankle or small leg portions of a taken game carcass into the recesses  118 ,  128 . However, when the rigid members  110 ,  120  are clamped toward each other sufficiently to cause the projections  105  to extend into the passages  106 , this will keep the members  110 ,  120  properly aligned as they move progressively toward each other while being clamped together. 
     The rigid members  210 ,  220  of the second tote embodiment  200  shown in  FIGS. 3 and 4  do not have a capability to turn relative to each other about the axis of the aligned passages  215 ,  225  because the rigid members  210 ,  220  are held in alignment by the threaded fasteners  290 . 
     When the two rigid members  310 ,  320  of the third embodiment are sufficiently separated from each other (for example, as shown in  FIGS. 5 and 6 ) that the generally rectangular projections  305  do not extend into the generally rectangular openings  306 , the rigid members  310 ,  320  are free to pivot about a quarter turn relative to each other due to the flexibility of such portions of the tow rope or cable  360  as extend between the separated members  310 ,  320 —which turning capability can assist during efforts to insert narrow ankle or small leg portions of a taken game carcass into the recesses  318 ,  328 . However, when the members  310 ,  320  are clamped toward each other sufficiently to cause the projections  305  to extend into the passages  306 , the insertion of the projections  305  into the openings  306  will keep the rigid members  310 ,  320  properly aligned as they move progressively toward each other while being clamped together. 
     To clamp the members  110 ,  120  of the first embodiment  100  toward each other, and to retain a clamped-together relationship of the members  110 ,  120 , a commercially available clamp assembly  170  preferably is installed on the flexible tow rope or cable  160  at a location above the upper rigid member  110 . By adjusting the position of the clamp assembly  170  along the tow rope or cable  160 , the first and second members  110 ,  120  can be forced to move relatively toward and each other, and can be retained closely together with the generally cylindrical projections  105  extending into the generally cylindrical openings  106  so a clamped-together state of the rigid members  110 ,  120  is maintained that grips and retains narrow ankle or small leg regions of the legs of a deer carcass or the like (not shown in the drawings hereof—however, as is shown in the previously mentioned patent to Burlison et al). 
     In preferred practice, the clamp assembly  170  is a type sold by The Lehigh Group of Macungie, Pa. 18062, product number 7097CL, which has an elongate, generally cylindrical, tubular body  172  into one end region of which extends a tubular plunger  174 . Although the clamp assembly  170  is sold as being primarily intended for use in the tightening of sagging clothesline, the clamp assembly  170  has been found to be usable as an element of the tote  100 . 
     The tubular housing  172  of the clamp assembly  170  encloses three steel balls (not shown) that are arrayed about the flexible tow rope or cable  160  and are pressed radially inwardly to engage and clamp the tow rope or cable  160  under the influence of a spring (not shown, but carried within the housing  172 ) unless a tubular plunger member  174  of the rope clamp assembly  170  is pulled axially outwardly relative to the housing  172  (in a direction as indicated by an arrow  175  in  FIGS. 1 and 2 ) to release the clamping action of the steel balls. 
     To utilize the rope clamp assembly  170  to move the rigid members  110 ,  120  toward each other, the housing  172  is moved along the tow rope or cable  160  into engagement with the upper surface  111  of the rigid member  110 . As the housing  172  of the rope clamp assembly  170  and the knot  162  clamp the rigid members  110 ,  120  therebetween, the members  110 ,  120  are forcibly moved toward each other in the direction of the arrows  107  that are shown in  FIGS. 1 and 2 . 
     To release a clamped-together relationship of the members  110 ,  120 , the tubular plunger member  174  of the rope clamp assembly  170  is pulled axially outwardly relative to the housing  172  in the direction of the arrow  175  shown in  FIGS. 1 and 2  to release the clamping engagement of the clamp assembly  170  on the flexible tow rope or cable  160 . 
     To clamp the rigid members  210 ,  220  of the second embodiment  200  toward each other, and to retain a clamped-together relationship of the members  210 ,  220 , the wing nuts  294  are tightened along the threaded fasteners  290 . To release a clamped-together relationship of the rigid members  210 ,  220 , the wing nuts  294  are loosened. 
     Referring to  FIG. 5 , the tow rope or cable  360  is threaded loosely downwardly through the aligned passages  315 ,  325 , then transversely through the cross-passage  329 , and then upwardly through the aligned passages  327 ,  317 . Pulling upwardly on the flexible tow rope or cable  360  by applying force to a handle  380  connected to an upper end region of the tow rope or cable  360  will tend to cause the upper rigid member  310  to move relatively downwardly toward the lower rigid member  320 , and will tend to cause the lower rigid member  320  to move relatively upwardly toward the upper rigid member  310 . Thus, pulling on the flexible tow rope or cable  360  will cause the rigid members  310 ,  320  to be clamped toward each other. 
     To retain a clamped-together relationship of the rigid members  310 ,  320 , a commercially available clamp assembly  370  may be installed on the tow rope or cable  360 . The clamp assembly  370  is preferably of a type shown in the drawings of U.S. Pat. No. 5,711,072 issued Jan. 27, 1998 to Carpenter, the disclosure of which patent is incorporated herein by reference. 
     Normally, the clamp assembly  370  grips the tow rope or cable  360 . However, when opposite end regions  371 ,  373  of the clamp assembly  370  are pressed toward each other, the clamp assembly  370  releases its grip on the tow rope or cable  360 , thereby permitting the clamp assembly  370  to be moved along the tow rope or cable  360 . For example, the clamp assembly  370  can have its opposite end regions  371 ,  373  pressed toward each other to permit the clamp assembly  370  to be moved downwardly along the tow rope or cable  360  and into engagement with the rigid member  310 , whereupon the end regions  371 ,  373  are released to permit the clamp assembly  370  to grip the tow rope or cable  360  to hold the rigid members  310 ,  320  in a clamped-together relationship that has been created by pulling on the tow rope or cable  360 . 
     To release a clamped-together relationship of the members  310 ,  320 , the opposite end regions  371 ,  373  of the clamp assembly  370  are pressed toward each other which again causes the assembly  370  to release its grip on the tow rope or cable  360  so the clamp assembly  370  can be moved upwardly along the tow rope or cable  360  away from the rigid members  310 ,  320  to release the clamped-together relationship of the members  310 ,  320 . 
     The tow ropes or cables  160 ,  260 ,  360  are preferably of about one-fourth inch in diameter, and preferably have a length of about thirty six inches. The passages  115 ,  125  and  215 ,  225  and  315 ,  325 ,  329 ,  327  and  317  through which the tow ropes or cables  160 ,  260 ,  360  are threaded, respectively, are sized to permit the tow ropes or cables  160 ,  260 ,  360  to move freely therethrough. In preferred practice, the cross-passages  319 ,  329  ( FIG. 5 ) of the third embodiment  300  are preferably somewhat wider than are the uniform diameters of the passages  315 ,  325 ,  317 ,  327 —which permits the knot  362  (best shown in  FIG. 5 ) to be sufficiently large to be unable to enter the passage  317  (or to enter either of the passages  325 ,  327  if the rigid members  310 ,  320  are reversed so that the member  310  is positioned to be the lower of the two rigid members  310 ,  320 , and the member  320  is positioned to be the upper of the members  310 ,  320 , hence the knot  362  is seated in one or the other of the cross-passages  319  or  329 , and needs to be prevented from entering one or the other of the adjacent passages  325 ,  327 ). 
     When the two rigid members  110 ,  120  of the first embodiment  100  are moved relatively toward each other, the substantially U-shaped, C-shaped or semi-circular recesses  118  of the first rigid member  110  align with and are intended to cooperate with the two spaced, substantially U-shaped, C-shaped or semi-circular recesses  128  of the rigid member  120 . If the members  110 ,  120  were to be clamped completely together, the recesses  118 ,  128  would then cooperate to provide a pair of spaced, substantially circular formations (typically of a diameter of about 1.25 inches) that preferably are suitably sized to receive, to grip, and to retain therein narrow ankle or small leg regions of the legs of a deer or other taken animal carcass. 
     The recesses  218 ,  228  of the second embodiment  200  and the recesses  318 ,  328  of the third embodiment  300  are preferably configured and sized substantially as has just been described in conjunction with the recesses  118 ,  128  of the first embodiment  100 . However, if hunters are taking larger four legged game than deer, the rigid members  110 ,  120  and  210 ,  212  and  310 ,  312  can, of course, be provided with somewhat larger radius recesses  118 ,  128  and  218 ,  228  and  318 ,  328 , respectively, that can cooperate to provide larger radius recess formations capable of receiving, gripping and retaining the somewhat larger ankle or leg regions of taken game. Likewise, if the tote  100  is to be used to drag somewhat smaller game carcasses, the recesses  118 ,  128  and  218 ,  228  and  318 ,  328  can be sized somewhat smaller. 
     In  FIGS. 1 and 2 , and in  FIGS. 3 and 4 , commercially purchased handles  180 ,  280  are shown connected to an end region of the flexible tow ropes or cables  160 ,  260 , respectively. In  FIGS. 5 and 6 , a somewhat less costly injection molded handle  380  of open construction is provided. The handle  380  has finger-receiving grip formations  382  (shown in  FIG. 5 ) and has a central opening  384  through which an end region of the flexible tow rope or cable  360  extends and carries a knot  364 . 
     By pulling on one of the handles  180 ,  280 ,  380  and hence on the tow ropes or cables  160 ,  260 ,  360 , the first, second and third tote embodiments  100 ,  200 ,  300 , respectively, can be used to drag a game carcass that has narrow ankle or small leg regions of two of its legs (not shown, but in a manner shown in the previously referenced Burlison et al patent) received in and securely gripped by the recesses  118 ,  128  or  218 ,  228  or  318 ,  328 , respectively. 
     Although not depicted in the drawings, the tote embodiments  100 ,  200 ,  300  may, in fact, be provided with two pairs or sets of the rigid members  110 ,  120  and  210 ,  220  and  310 ,  320 , respectively, at spaced locations along the tow ropes or cables  160 ,  260 ,  360 , respectively, so that, for example, narrow ankle or small leg regions of front legs of a taken game carcass can be inserted in a first set or pair of the rigid members  110 ,  120  or  210 ,  220  or  320 ,  330 , and narrow ankle or small leg regions of rear legs of the taken game carcass can be inserted in a second set or pair of the rigid members  110 ,  120  or  210 ,  220  or  310 ,  320 , respectively. If two sets or pairs of the rigid members  110 ,  120  or  210 ,  220  or  310 ,  320  are deployed on the same tow rope or cable  160 ,  260 ,  360 , respectively, the tow ropes or cables  160 ,  260 ,  360  preferably are longer than a normal length of about 36 inches; separate clamp assemblies  170  are be provided for use with each set or pair of the rigid members  110 ,  120  of the first embodiment  100 ; and separate clamp assemblies  370  are provided for use with each set or pair of the rigid members  310 ,  320  of the third embodiment  300 . 
     Referring to  FIG. 7  in conjunction with  FIGS. 5 and 6 , the identical rigid members  310 ,  320  of the third embodiment  300  can be seen to have a relatively long central region  400  that bridges between two identically curved portions  414 ,  424  that define the substantially U-shaped, C-shaped or semi-circular recesses  318 ,  328 . The generally rectangular alignment projections  305  extend from the central regions  400 , and the mating openings  306  are formed in the central regions  400  at short distances spaced from the projections  305 . Reinforcing formations  440  also bridge between the curved portions  414 ,  424  which define the recesses  318 ,  328 , to ensure that the curved portions  414 ,  424  do not deform or break while in use. 
     As will be apparent from the foregoing description, various alternate forms of totes that utilize pairs rigid members (that resemble the rigid members.  110 ,  120  or  210 ,  220  or  310 ,  320 ) that can be clamped toward each other to receive and grip narrow ankle or small leg regions of at least two legs of a taken game carcass can incorporate the pith and thrust of the present invention without conforming precisely to the configuration of the embodiments  100 ,  200 ,  300  that are described in the specification and depicted in the drawings hereof. 
     Although the invention has been described in a preferred form with particularity, it is understood that the present disclosure of embodiments have been made only by way of example, and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
