referring to fig1 and 2 , the present invention concerns a fishing rig consisting of seven components including : a base 12 , an upright 14 , a triggering device 16 , a fishing rod including a handle portion 18 and a pole portion 20 , a flag with staff 22 and a fitting 24 . the base 12 ( see fig5 ) is a unitary plastic molded member consisting of a longitudinal central member 26 and of a cross member 28 , both of which are reinforced by the presence of opposite oblique side members 30 and 32 , 34 and 36 . the rear of the base displays an upstanding cylindrical hollow portion 38 while the front of the base displays , on the central member 26 , two successive pairs of ears 40 , 42 and 44 , 46 . the bottom face of the central member 26 between the pairs of ears is concave as explained further hereinbelow . members 26 and 28 each have reinforcing ribs 27 and their extremities each have a hole 29 allowing the base to be fixed to the ice surface or other supporting surface . referring to fig3 the upright 14 comprises a vertical portion 48 with a rounded base 50 which is adapted to be received between the two ears 40 and 42 and on the concave lower surface therebetween on the base . the upper portion of the upright 48 is rearwardly oblique and is defined by a pair of spaced side members 52 and 54 defining a yoke . a pair of cross - pins 56 and 57 extends transversely between the two members 52 and 54 . the lower end of the upright has two opposite rounded flanges 58 which are adapted to sit and ride on the upper rounded edges of the ears 40 and 42 . the lower end of the oblique side members 52 and 54 displays a rounded recess 62 at the front thereof . the triggering mechanism 16 is a t - shaped member integrally formed , at its base , with a transverse pivot 66 having two grooved areas which are adapted to be fittingly inserted into the rounded recesses 62 of each member 52 , 54 of the yoke . the opposite extremities of shaft 66 have a semi - spherical surface 66a ; however , as can be seen in fig4 one extremity of this surface has a segmented portion 68 , the function of which will be described hereinafter . the handle portion 18 of the fishing rod includes a hand gripping section 70 , having a hook - like extremity 72 , and a housing 74 which is formed of opposite circular side extensions 75 . a reel 76 is rotatably secured in housing 74 by means of a manual lever 78 which has a rectangular cross - member 79 . openings are provided in both circular side extensions of the housing 74 so that lever 78 may be located on either side ( for left - handed or right - handed fishermen ). portion 18 of the handle also comprises a c - shaped catch 80 defining an open slot 82 in which is positioned the cross - pin 56 of the upright which acts as a fulcrum point when the fishing rod is placed on the upright . the other portion 20 of the fishing rod comprises a standard pole 84 with circular rings 86 through which extends a fishing line 88 , the pole being tight fitted in the extremity of the handle portion 18 . the flag 22 consists of a visual signaling element 90 adjacent its extremity 22a and of a flexible staff 92 . fitting 24 comprises a cylindrical lower portion 94 which is adapted to be snuggly received in the hollow cylindrical extension 38 of the base . it further comprises , at the upper portion , two space side members 96 and 98 between which is adapted to sit the extremity 72 of the fishing rod . one side member 96 includes , on its outer wall , a cylindrical hollow housing 100 to receive the lower end of the flexible staff 92 . fitting 24 thus serves to support the flag as well as the fishing rod when in a tip - up position . the assembly of the fishing rig is accomplished as follows . the upright 14 is positioned vertically with its base 50 inserted between the two supporting ears 40 and 42 of the base . a locking pin 102 ( see fig1 ) is inserted through an appropriate side opening 103 in each ear in registry with hole 51 of the upright ( see fig3 ). the fishing rod is then positioned so that its catch 80 engages the cross pin 56 of the upright ( as shown in fig4 ); with the fishing rod placed in its tip - up position , extremity 72 of the rod is received between the two sides members 96 and 98 of fitting 24 . the lower end of the flag staff is fitted in the cylindrical housing 100 . the flag staff is then flexed and its upper extremity 22a is located to abut the segmented portion 68 of the end surface 66a of pivot 66 . line 88 is then pulled away from the pole and loosely fitted around the head 64 of the t - shaped portion of the triggering device . referring to fig4 whenever a pull is exerted on the line in the direction indicated by arrow 104 , the triggering device 16 pivots about its axis 66 ( as indicated by arrow 105 ). as the semi - spherical surface 66a , rotates , it slides under the staff extremity 22a thus releasing the staff to its normal vertical position ( as indicated by arrow 106 ). also , the line is freed from head 64 . as the pull becomes significant , the fishing rod pivots about axis 56 and adopts the position shown in fig2 with its tip down over hole 110 . in this position , cross - pin 56 now slides in the uppermost extremity of slot 82 of catch 80 . the obliqueness of portion 54 relative to the main vertical portion of the upright 14 provides maximum resistance to the pull in the direction 107 ( in fig2 ). the opposing force is in line with the pulling force of the rod . if the upright were in a vertical position , there would be a tendency for the entire assembly to pivot with the possibility of the rod being unhooked and being pulled into the hole . on the other hand , with the arrangement shown in the drawings where the base is not secured to the ice surface , there is tendency of the assembly to be drawn or to slide on the ice surface to a position adjacent the hole . in cases where an important pull would cause the assembly to reach the position such as shown in fig6 it can be seen that the particular structural supporting configuration of the rod to the upper part of the upright makes it difficult for the fishing rod to be removed from the upright . as shown in fig6 a relatively large hole would be required for the entire fishing rig to be drawn underwater . another feature of the present invention resides in the particular construction of the base 12 , which allows fishing to be carried out in the manner shown in fig7 . this may be preferred in cases where movement of the fishing rod in the water is desired to effect continuous breakage of the thin ice 112 being formed on the surface of the water . still , in cases where there is not sufficient movement of the rod to cause ice breakage , the retrieval of the fishing rod ( as indicated by arrow 152 in fig8 ) by pivoting the upright 14 about pivot 102 will break the thin ice layer . the upright is , in this case , positioned horizontally between the frontmost ears 44 and 46 of the base and is secured therebetween by means of a pin 102 with the opposite arcuate portions 58 resting on the corresponding upper edges of the ears ( see fig9 ). a ball - and - spring arrangement 120 may be used to secure the pin 102 in the assembly of the upright 14 to the base 12 . the base includes an opening 122 rearwardly of ears 44 and 46 so that the lower cylindrical portion 94 of fitting 24 may be received therein ( see fig7 ). in this arrangement , all of the components of the embodiment illustrated in fig1 to 6 are used ; however , an additional member is required . indeed , an elongate extension member 130 formed of two telescopically engaged members 132 and 134 is used . each member has a c - shaped extremity 136 , 138 for respectively engaging the cylindrical portion 140 of the lever 78 and one of the two side arms 142 of the t - shaped triggering device 16 . in this embodiment the engagement of the flag staff extremity 22a with the triggering device 16 is accomplished in the same manner as that described above with respect to fig1 to 6 . a pull on line 88 in the direction of arrow 150 causes the rotation of the lever 78 and , through its telescopic connecting member 130 , the pivotal movement of device 16 which then triggers the release of staff 22 again in the same manner as that described above . as illustrated in fig8 retrieval of the fishing rod is accomplished by simply pivoting the upright 14 about pin 102 in the direction of arrow 152 . although the invention has been described above with respect with two specific forms , it will be evident to a person skilled in the art that it may be modified and refined in various ways . for example , although not described , the base may be constructed in a manner that all of the other components of the rig may be snuggly received thereon . it is therefore wished to have it understood that the present invention should not be limited in scope , except by the terms of the following claims .
a portable knockdown fishing rig which includes a base , a fishing rod support , a flag and staff having its lower end mounted to the base and its upper end adapted , in a flexed condition , to be loosely engaged to a line responsive triggering mechanism also mounted to the support . a pulling force exerted on the fishing line causes the triggering mechanism to release the flag staff thus indicating the catch of a fish . in one embodiment , the upper part of the support is so shaped as to oppose tilting of the entire fishing rig when an important pulling force is exerted .
