A mechanism by which in the event the hook or leader line become snagged, the leader line would be lost but the casting float enclosure separately attached to the fishing line will be retrieved. A separating cage with a portion of the casting float to separate the hook and bait form the operating components of the casing float.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to fishing and in particular, to the process of casting a fishing line with bait on a hook. The present invention also relates to the field of floats which retain a portion of the line above water after the float hits the water. 
     2. Description of the Prior Art 
     The closest prior art of which the present inventor is aware is the present inventor&#39;s own U.S. Pat. No. 3,611,613 issued on Oct. 12, 1971 and entitled “Casting Float For Live Bait” (the “&#39;613 patent”). 
     This &#39;613 patent discloses some of the concepts of the present invention but the present inventor discovered important flaws in his previous invention which impacted the effectiveness of the invention and potential loss of the invention in water. The inventor&#39;s prior invention created a possible intermingling of the hook and bait with a portion of an internal float and also has design defects which sometimes caused the bait to become entangled with the internal portion of the float, thereby significantly reducing the ability of the bait to enter the water to attract fish. 
     In particular, the leader line to which the hook is attached was wrapped around a cylinder within the globe float. As a result, after the float opened by impact of the float on the water, the leader line and hook remained caught within a portion of the float and therefore, the hook and bait thereon was ineffective. In addition, in the previous invention, the fishing line was directly attached to the leader line. The fishing line was heavier and stronger than the leader line. If the hook became tangled in rocks, plants or other objects on a lake bed or sea-floor, the fisherman would pull on the fishing line to extract the hook from where it was entangled or caught. As a result, the leader line which had less strength than the fishing line would break off. Since the leader line was affixed to the casting float, the break-off of the leader line also resulted in the loss of the casting float. 
     There is a significant need for an improved invention which rectifies the above identified problems with the present inventor&#39;s prior invention. 
     SUMMARY OF THE INVENTION 
     The present invention is an improvement over the present inventor&#39;s prior invention protected by U.S. Pat. No. 3,611,613. The feature that the prior invention and present invention have in common is that they are both enclosed in a globe split into two separate halves which are rotatably attached at one location to enable the halves to split to an opened condition being attached to one another only by the rotatable attaching mechanism (such as rings). An improvement in the present invention is that the globe is forced to be partially open during casting to assure that water will run into the float when it hits the water. 
     The shape does not have to be a globe but it is an enclosure that has a float on each of the separate halves of the enclosures. In a preferred embodiment, both halves include a flat float and one of the halves also includes a bulbous float. 
     The two half globe-shaped halves of the enclosure are held together by a dowel affixed to one half of the bulbous float in a second half globe-shaped half which dowel then extends into an opening in a separation member in the first half globe-shaped half which serves to retain the two halves together but also causes the two half globe-shaped halves to be partially opened during casting so the complete globe has an opening at the location where the two halves are adjacent to each other. When the casting float enclosure hits the water after the fishing line is cast, the impact causes the dowel and portion of the bulbous float to which the dowel is attached to become separated from the opening in the separation member so that water runs into the float and the two halves of the enclosure fold open and they then can float in the water which allows the hook and bait to drop into the water. 
     The major negative of prior fishing apparatus which included a hook onto which bait such as a worm, salmon eggs, a piece of fish or any other conventional bait was affixed, which the present inventor&#39;s earlier patent solved, was that after the fisherman attached the bait to a hook, whether the bait was a nightcrawler, salmon eggs, etc., and the fishing line was cast out into the water, the fisherman could not see the end of the attached leader line to which the hook and bait were attached. Because of the force of the casting or when the hook hit the water, many times the bait was released from the hook inadvertently and the bait flew off the hook before it ever hit the water or when it hit the water and consequently the fisherman was unknowingly fishing with a line that had no bait on it. 
     The improvement of the present inventor&#39;s prior patent was that the leader line was wound around a post within the enclosure with the hook and bait inside the enclosure so the enclosure retained the hook and the bait inside the enclosure while the fishing line was flying through the air after being cast from the reel and the enclosure casting float only opened upon impact when the casting float hit the water. Therefore, the fisherman did not run into the problem of the earlier fishing hook and bait arrangements where the bait came loose from the hook. With the present inventor&#39;s prior innovation, the bait and hook were retained in the casting float enclosure and the hook and bait were only released when the casting float enclosure hit the water and opened. 
     The prior invention resolved the problem of the bait inadvertently falling off the hook during casting but it created problems that the prior art did not address. The problems were as follows: 
     (1) Since the leader line was wound around an internal post, when the casting float enclosure opened upon impact with the water, the hook and bait remained in the enclosure; 
     (2) The design of the prior invention required the fishing line to be affixed to the leader line. If the enclosure and/or hook became entangled in some way (to a rock, plant, seaweed, kelp, coral, etc.), to free the line, a force from the rod and reel needed to be exerted. Since the fishing line is much heavier and stronger than the leader line, the leader line would break away. The fisherman therefore not only lost the leader line and attached hook and bait, but also lost the casting float enclosure which was attached to the leader line. 
     The present invention involves the following improvements to address the above described problems with the inventor&#39;s prior invention: 
     (1) One improvement is that the bait and hook to which the bait was attached and a small portion of the leader line attached to the hook, which leader line can be shorter for shallow water (3 to 4 feet) or longer for deeper water (8 to 10 feet) are still in the casting float enclosure but the opposite end of the leader line is attached to an attachment member of the first half globe-shaped half so that a large portion of the leader line extends outside of the casting float enclosure. Therefore, once the casting float enclosure splits open, the hook with the bait and the leader line go outside into the water. 
     (2) The second innovation which is a significant improvement over the earlier patent of the present inventor is that the end of the fishing line away from the reel is separately attached to the attachment member of the first half of the globe-shaped half. Through this novel separation of the fishing line and leader line, if the hook gets entangled in some seaweed or rocks and it is 10 to 50 feet out, the fisherman cannot see it and after a while the fisherman realizes there is a problem. The way to solve the problem is that the fishing line is typically a heavier 8 or 10 pound test line, while the leader line that is attached to the hook may be 4 to 5 pounds. In this way, the leader line is much lighter than the fishing line so if the hook or any part of the leader line is snagged and is stuck, the fisherman would pull on the fishing line through the rod and reel and the leader line would break off from the attachment member on the first globe-shaped half of the casting float and therefore, the leader line would be lost with the hook and bait but the casting float having the fishing line separately attached to the attachment member would be retrieved and not lost. 
     (3) A third ancillary improvement is for a second mating half of the half globe-shaped float to contain a bulbous float where the bulbous float is separated into two halves. A first half of the bulbous float is affixed to a hard material blocking wall so that the open end of the first half of the bulbous float faces toward the separation member when the two halves of the globe-shaped casting float are retained together and partially opened. The second half of the bulbous float has an opening to face the fixed first half of the bulbous float to form a complete bulbous float when the two halves come together. The second half of the bulbous float is attached to a dowel. The first semi globe-shaped half of the casting float includes a hard material horizontal wall with multiple openings, which horizontal wall is attached adjacent the top of the blocking wall and attached to a second hard material wall parallel to the blocking wall to create a complete separation cage between the bulbous float and remaining interior of the second semi globe-shaped half of the casting float. The inclusion of a cage comprised of the blocking wall, the horizontal wall, and the second hard material wall at least partially surrounding the bulbous float prevents the bulbous float half and dowel from coming in contact with the bait. The second semi globe-shaped half of the casting float also contains a small vertical stop member with a v-shaped opening located outside of the second hard material wall and horizontal wall and adjacent an interior surface of the second semi globe-shaped half. The first mating half of the semi globe-shaped half of the casting float contains a vertical separation member having an elongated section terminating in a v-shaped tip matching the v-shaped opening in the stop member and also having a transverse opening extending through the elongated section of the separation member. When the first and second semi-globe halves are brought close to each other, the vertical separation member is inserted into the vertical stop member and the dowel is aligned with the transverse opening in the elongated section of the separation member so that the dowel extends through an aligned opening in the second had wall and into and through the opening in the vertical separation member and retains the two semi globe-shaped halves close to each other. The stop member is configured to receive the tip of the elongated section of the separation member and configured to prevent the casting float from entirely closing by leaving a small gap between the two semi globe-shaped halves so that water can rush into the casting float when it hits the water. 
     It is an object of the present invention to provide a mechanism by which the hook and leader line are released from the casting float enclosure upon its impact with the water so that once the casting float enclosure opens, the leader line with hook and bait go into the water to attract a fish. 
     It is also an object of the present invention to provide a mechanism by which in the event the hook or leader line become snagged, the leader line would be lost but the casting float enclosure separately attached to the fishing line will be retrieved. 
     It is additionally an object of the present invention to provide an improved internal structure in the casting float to prevent the hook and bait from coming in contact with the bulbous float and dowel, and a mechanism by which the two mating semi globe halves are retained together to permit water to enter the casting float when it hits the water.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     Referring to  FIG. 1 , there is illustrated a conventional fishing rod  300  with a reel  310  and spaced apart line rings  312 ,  314  and  316 . A fishing line  200  is wound on reel  310 , extends through line rings  312 ,  314  and  316  and then extends outwardly away from the fishing rod  300 . At the distal end  210  of the fishing line  200 , the fishing line is attached to a line attachment mechanism (to be discussed in detail later on) of the present invention openable casting float  10 . 
     When a fisherman (not shown) engages in casting the fishing line  200 , the line flies through the air and comes down over a body of water  400  which can be a lake, a river, an ocean, etc. 
     Referring to  FIGS. 2 through 5 , the present invention casting float  10  is illustrated in the partially closed position in  FIG. 2 , an interior perspective view of the casting float in  FIG. 3 , an enlarged interior perspective view of the second semi globe-shaped half of the casting float in  FIG. 4 , and an exterior perspective view of the casting float in  FIG. 5 . The casting float  10  comprises a mating first semi globe-shaped half  20  and a mating second semi globe-shaped half  70 . The mating first semi globe-shaped half  20  has a circumferential exterior wall  30  with a top surface  32  and an exterior sidewall  34  and an interior sidewall  36  which surround an interior chamber  37  with an opening  39 . The sidewall  34  ends in a circumferential rim  38  surrounding opening  39 . A separation member  40  has an elongated section  42  with a transverse opening  44  extending through the elongated section  42 . The distal end  45  of elongated section  42  ends in a tip  46  having a given shape such as “v”-shaped as illustrated in  FIG. 5 . At its proximal end  41 , the separation member  40  is attached to a spacer member  48 , which spacer member  48  is attached to interior sidewall  36  so that the separation member  40  is at a given distance “D1” from the interior sidewall  36 . The separation member  40  extends vertically away from top surface  32  and partly away from the circumferential rim  38 . The exterior sidewall  36  also includes a line attachment member  50  extending transversely to and in approximately the same plane as the circumferential rim  38  and having an opening  52  extending therethrough. The interior chamber  37  further comprises a first flotation member  60  which by way of example, is a disc  60 A leaving air pocket  60 B between disc  60 A and top surface  32  and an upper portion of interior sidewall  36 . The first flotation member  60  enables mating first half enclosure  20  to remain buoyant and afloat on the water  400  when the casting float  10  is open. 
     In one embodiment, the line attachment member  50  is between retaining rings  292  and  294  of rotatable connecting mechanism  290  discussed below. 
     The mating second half enclosure  70  has a circumferential wall  72  with a top surface  74 , an exterior sidewall  76  and an interior sidewall  78  which surround an interior chamber  77  with an opening  79 . The exterior sidewall  76  ends in a circumferential rim  80  surrounding the opening  79 . The interior chamber  77  further comprises a second flotation member  90  which by way of example, is a disc  90 A leaving air pocket  90 B between disc  90 A and top surface  74  and an upper portion of interior sidewall  76 . The second flotation member  90  enables mating second semi globe-shaped half  70  to remain buoyant and afloat on the water  400  when the casting float  10  is open. 
     (1) One improvement is that the bait  100  and hook  110  to which the bait  100  is attached and a small portion of the leader line  120  is attached at its distal end  122  to an attaching loop  102  of hook  110 , which leader line  120  can be shorter for shallow water (3 to 4 feet) or longer for deeper water (8 to 10 feet) are still in the casting float enclosure  10  but the opposite proximal end  124  of the leader line  120  is attached through opening  52  of attachment member  50  of the first half semi globe-shaped half  20  so that a large portion of the leader line  120  extends outside of the casting float enclosure  10 . Therefore, once the casting float  10  splits open, the hook  110  with the bait  100  and the leader line  120  go outside into the water. 
     (2) The second innovation which is a significant improvement over the earlier patent of the present inventor is that the distal end  210  of the fishing line  200  away from the fishing rod  300  and reel  310  is separately attached through opening  52  of attachment member  50  of the first half of the globe-shaped half  20 . Through this novel separation of the leader line  120  and fishing line  200 , if the hook  110  gets entangled in some seaweed or rocks and it is 10 to 50 feet out, the fisherman cannot see it and after a while the fishes man realizes there is a problem. The way to solve the problem is that the fishing line  200  is typically a heavier 8 or 10 pound test line, while the leader line  120  that is attached to the hook  110  may be 4 to 5 pounds. In this way, the leader line  120  is much lighter than the fishing line  200  so if the hook  110  or any part of the leader line  120  is snagged and is stuck, the fisherman would pull on the fishing line  200  through the rod  300  and reel  310  and the leader line  120  would break off from the attachment member  50  on the first semi globe-shaped half  20  of the casting float  10  and therefore, the leader line  120  would be lost with the hook  110  and bait  100  but the casting float  10  having the fishing line  200  separately attached to the attachment member  50  would be retrieved and not lost. 
     (3) A third ancillary improvement is for a second mating half  70  of the half globe-shaped float  10  to contain a bulbous float  140  where the bulbous float  140  is separated into two halves. A first half  132  of the bulbous float  140  is affixed to a hard material blocking wall  160  so that the open end  134  of the first half  132  of the bulbous float  140  faces toward the separation member  40  when the two halves  20  and  70  of the globe-shaped casting float  10  are retained together and partially opened. The second half  136  of the bulbous float  140  has an opening  138  to face the fixed first half  132  of the bulbous float  140  to form a complete bulbous float  140  when the two halves  132  and  136  come together. The second half  136  of the bulbous float  140  is attached to a dowel  150 . The second semi-globe-shaped half  70  the casting float  10  includes a hard material horizontal wall  170  with multiple openings  172 A,  172 B,  172 C,  172 D,  172 E,  172 F,  172 G,  172 H,  172 I,  172 J,  172 K and  172 L which horizontal wall  170  is attached adjacent to the top  162  of the blocking wall  160 , and attached at its opposite end to a second hard material wall  160 A which is parallel to first hard material wall  160  to create a complete separation cage  180  between the second half  136  of bulbous float  140  and dowel  150  and the remaining interior  77 A of the second semi globe-shaped half  70  of the casting float  10 . The inclusion of a cage  180  comprised of the blocking walls  160  and  160 A and the horizontal wall  170  at least partially surrounding the second half  136  of bulbous float  140  and dowel  150  attached to the second half  136  at the dowel&#39;s proximal end  152  prevents the bulbous float half  136  and dowel  150  from coming in contact with the bait  100 . The second semi globe-shaped half  70  of the casting float  10  also contains a small vertical stop member  166  with a v-shaped opening  168  located outside of the second hard wall  160 A and horizontal wall  170  and affixed to the interior surface  78  adjacent the exterior surface  76  of the second semi globe-shaped half  70 . The first mating half of the semi globe-shaped half  20  of the casting float  10  contains the vertical separation member  40  having an elongated section  42  terminating in a v-shaped tip  46  matching the v-shaped opening  168  in the stop member  166  and also having a transverse opening  44  extending through the elongated section  42  of the separation member  40 . The second hard wall  160 A also has an aligned opening  160 AA through which the dowel  150  passes. When the first and second semi-globe halves  20  and  70  are brought close to each other, the vertical separation member  40  is inserted into the matching v-shaped top  168  of the vertical stop member  166  and the dowel  150  is aligned with the transverse opening  44  in the elongated section  42  of the separation member  40  so that the distal end  153  of the dowel  150  extends into and through the opening  44  in the vertical separation member  40  and retains the two semi globe-shaped halves  20  and  70  close to each other. The dowel has a proximal end  152 . When the float  10  is on land, it is rotated 90 degrees counterclockwise from the position shown in  FIG. 1  so that the distal end  153  of the dowel  150  will extend into and through the opening  44  in the vertical separation member  40  by gravity and will remain in that condition until the float hits the water. The vertical stop member  166  is configured to receive the tip  46  of the elongated section  42  of the separation member  40  and is sufficiently elevated to prevent the casting float  10  from entirely closing and leaving a small gap  8  between the two semi globe-shaped halves  20  and  70  so that water  400  can rush into the casting float  10  when it hits the water  400 . 
     Referring to  FIG. 5 , a rotatable connecting mechanism  290  rotatably retains mating first half enclosure  20  and mating second half enclosure  70  together. One example of a rotatable connecting mechanism  290  is a first ring  292  extending through opening  31  in circumferential walls  34  and  36  and opening  71  in circumferential walls  76  and  78 . A second ring  294  extends through opening  33  in circumferential walls  34  and  36  and opening  73  in circumferential walls  76  and  78 . 
     In the semi-closed condition, dowel  150  extends through opening  44  in separation member  44  partially enclosing the casting float  10  to retain the casting float  10  in the semi closed condition as illustrated in  FIG. 2 . The rings  292  and  294  rotatably retain the two semi globe-shaped halves together. The cage  180  extends across a portion of the interior chamber  77  of second semi globe-shaped half  70  and partially extends across the interior chamber  77  and leaves an unenclosed section  77 A into which the bait  100  and hook  110  are retained. The cage  180  prevents the bait  100  and hook  110  from coming in contact with the bulbous float half  136  and dowel  150 . When the casting float enclosure  10  hits the water  400 , the impact of the force of hitting the water causes the dowel  150  to move away from opening  44  in the separation member  44 , resulting in water flowing into the float through gap  8  and openings  172 A through  172 L in horizontal wall  170  so that the two semi globe-shaped halves  20  and  70  rotating about rotation means such as rings  292  and  294  separate into the opened condition illustrated in  FIGS. 3 and 5 . The entire casting float  10  and all of its components can be made of material selected from the group consisting of plastic and polyvinyl. The two semi globe-shaped halves  20  and  70  of the casting float  10  are face down in the water as illustrated in  FIG. 5 , with flotation members  60  and  60 A and bulbous float  40  enabling the two halves to float on the water. 
     Although the preferred embodiment has been described in great detail, it can be more broadly defined. For example, the dowel  150  and separation member  40  can be broadly defined as engaging member as described in the more detailed description of the invention at the end of the Summary section of this patent application. Other features can be also be described in more detail and are not limited to the specific terminology used in the patent application. While described as semi globe-shaped members, each of the halves of the casting float can more broadly be described as hemispherical and also while described as semi spherical as well as semi globe-shaped, it will be appreciated that it is within the spirit and scope of the present invention for the first mating half and a second mating half to be any convenient shape and is not restricted to a semi globe-shape or hemispherical. 
     Of course the present invention is not intended to be restricted to any particular form or arrangement, or any specific embodiment, or any specific use, disclosed herein, since the same may be modified in various particulars or relations without departing from the spirit or scope of the claimed invention hereinabove shown and described of which the apparatus or method shown is intended only for illustration and disclosure of an operative embodiment and not to show all of the various forms or modifications in which this invention might be embodied or operated.
