fig1 - 5 inclusive show a preferred embodiment of the invention under one of a number of types of trigger setting . in this respect , the invention comprises an automatic hook setting fish rod holder identified generally at 10 and shown in fig1 as supporting or holding a fishing rod identified generally at 12 having a handle or butt end 14 from which extends a fiberglass or bamboo rod portion 16 whose tip portion 18 extends well beyond the end of fishing rod holder 10 . at the butt end 14 or handle portion of the fishing rod 12 , there is mounted a reel 20 from which a line 22 extends passing through a plurality of guides 19 spaced along the length of the rod portion 16 of the fishing rod and fixed thereto . the automatic hook setting fishing rod holder 10 which may be formed of metal or plastic parts , is preferably formed of a bowed steel rod indicated generally at 24 which may be approximately 3 feet long and formed of steel rod stock , 1 / 4 inch , 5 / 16 inch , or 3 / 8 inch in diameter , as desired . the rod 24 carries near its lower end 30 and just above a triangular sheet metal plate or spade 28 welded to the side of the rod 24 , a fish rod handle or butt end support pipe 26 , which is hollow and which has at its upper end 32 a notch 33 on one side which may receive reel 20 . the triangular plate or spade 28 permits the operator to place his foot on its upper edge 29 and force the pointed tip end into the ground to securely plant the lower end 30 of the support rod 24 into the ground . the support rod 24 is bowed such that its outboard end 35 is almost but not quite parallel to the ground receiving the same . the outboard end 35 of the support rod terminates in a u - shaped fishing rod latch member 34 formed of sheet metal including a u - shaped base 36 terminating in ends or projections 38 and 40 which are bent generally at right angles to base 36 forming a u - shaped recess 42 . one projection 40 of member 34 forms a frictional locking surface 39 while the other right angle projection 38 supports a pin 44 which defines the pivot axis of trigger shown generally at 46 in the form of an elongated metal strip , pivotably mounted intermediate of its ends but close to one end , forming a short length portion 48 which spans recess 42 and frictionally engages the friction surface or face 39 of projection 40 to lock or restrain the trigger 46 from pivoting about the axis of pivot pin 44 . trigger portion 50 carries a pair of upright pins or dowels 52 and 54 fixedly mounted to the upper face of the strip at points remote from pivot axis defined by pin 44 . the pins or dowels 52 and 54 act to define a diversion path for the line 22 away from the fishing rod portion 16 as it extends between guides 19 to each side of member 34 , see fig2 . as may be seen in contrasting fig2 and 4 , the fishing rod holder 10 is set up such that the handle or butt end of the rod 12 is received within the tube or pipe 26 , the outboard portion of the fishing rod is bowed in conformance with bowed configuration of the support rod 24 and a portion of the fishing rod 16 intermediate of the tip end 18 and the butt end 14 is positioned within the recess 42 defined by the u - shaped latch member 34 and the trigger is pivoted to a position where portion 48 straddles recess 42 and is in frictional contact with friction surface 39 defined by the right angle projection 40 . the fishing rod is securely locked in its bowed condition setting up a spring force by the flexed condition of the rod storing energy which , upon release of the trigger , causes the rod to straighten , the amount of movement of the tip end in straightening acting to move the line 22 sufficiently to automatically set the hook ( not shown ) at the outboard end of the line . all of this is accomplished by the fish biting on the bait attached to the hook . as seen in fig2 and 3 , the fish line 22 as it passes from the reel 20 towards the tip end 18 of the fishing rod , is stretched about the tension dowels or pins 52 and 54 , the line 22 being bent to the left as it passes about pin or dowel 54 , and being wrapped clockwise about the outboard dowel or pin 52 prior to passing through the next ring guide 19 outboard of the trigger 46 . the fish biting on the bait or lure causes an increase in tension on line 22 and causes the trigger 46 to rotate clockwise about pivot pin 44 as seen by the arrow 60 , fig3 tending to straighten out and at the same time as further seen in fig4 in sequence , causing the portion 48 of strip 50 to move away from friction surface 39 and open up the recess 42 to release the flexed fishing rod 16 from latch member 34 , the extent of this movement from flexed to straightened or unflexed position as shown by arrow 62 , fig4 being sufficient to automatically hook the fish . the simplified automatic hook setting fishing rod holder of the present invention has great versatility both in terms of the size and length of rod that it holds or supports , and the tension required to trigger the release of the rod from its bowed position to its straightened , hook setting position , the sequence being shown in fig2 and 4 . for instance , reference to fig6 shows that the line 22 which extends from the reel 20 passes clockwise , first about the outer pin or tension dowel 52 and then counterclockwise about the inner pin or dowel 54 prior to further extending along the rod portion 16 captured by guides 19 . as another variation , this provides for a different tension force necessary to release the fishing rod section 16 from that shown in fig2 and 4 . additional different trigger settings may be maintained by simply having line 22 pass clockwise about pin 52 or pin 54 without touching the other . obviously , the force acting through the line 22 on the pin 54 is transmitted by way of the pivot pin 44 to the friction engagement area between the right angle projection 40 and the portion 48 of the trigger 46 . further , while the steel support rod forming the basic element of the automatic hook setting fishing rod holder of the present invention has been stated as preferably being approximately 3 feet long and formed of 1 / 4 inch , 5 / 16 inch or 3 / 8 inch steel rod stock , the dimensions and size of this member may be readily varied . furthermore , while the u - shaped latch member 34 may be cut from a 5 / 8 inch washer whose ends are bent over to form projections 38 and 40 , obviously this member may be formed from other than a metal washer and of different size and of different material . typically , the hook setting trigger 46 is formed of metal strap material and may be 7 inches in length , 1 / 8 inch in thickness and 1 / 2 inch in width . variations may be made without differing from the invention . the dowels 52 and 54 are preferably 3 / 4 inch in length and formed of a 1 / 8 inch diameter material , the pipe 26 may be formed on 1 inch pipe stock cut to a 4 inch length and mounted approximately 8 inches up from the bottom by welding the same to the side of the steel rod 24 . the spade or plate 28 may be formed of triangular steel plate 1 / 8 inch in thickness in triangular form having a horizontal edge 5 / 8 inch in width and inclined edges leading therefrom and intersecting approximately 4 inches in length ; preferably the triangular spade plate is welded to rod 24 about 3 inches up from the bottom of the rod from the terminal end 30 of the rod . while the invention has been particularly shown and described with reference to a preferred embodiment thereof , it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention .
a bowed steel support rod has one end inserted in the ground and the other extending upwardly therefrom . a fishing rod has its butt end fixed to the support rod near the point of insertion in the ground and an intermediate portion is captured within a u - shaped opening of a latch member fixed to the outboard end of the rod and held thereby by a pivotable trigger which overlies the open end of the u - shaped latch member and is frictionally maintained in position . the tension of the fishing line acts on the trigger to pivot the trigger upon the fish striking the lure on the end of the line and rotates the trigger to release the bowed fishing rod which flexes to automatically set the hook .
