Abstract
Abstract This invention relates to an ice fishing tip-up and more particularly to a means for activating an audible or visual indicator to alert a fisherman when a fish has engaged a hook of the ice fishing tip-up. The device is comprised of a switch which interconnects the audible or visual indicator to a power source. The switch has terminals normally biased toward a closed position whereby a first terminal is in contact with a second terminal. An insulator is placed between the terminals of the switch such that the terminals are not in contact. The insulator is then removed from between the terminals in response to an increase in tension in the fishing line when a fish strikes the hook. The removal of the insulator from between terminals causes the switch to close, thereby activating the audible or visual signal to alert the fisherman.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and fishing line wound on the spool, comprising: an elongated, flexible pole having first and second ends, the pole movable from a first set position to a second alert position in response to an increase in tension in the fishing line; a switch interconnecting the indicator to a power source, the switch having first and second terminals normally biased toward a closed position such that the first terminal is in contact with the second terminal; a flag affixed to the elongated pole for use as an insulator between the terminals of the switch when the pole is in the set position; and means for removing the flag from between the terminals of the switch in response to an increase in tension in the fishing line.
Claim 2
Independent Claim
142 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and fishing line wound on the spool, comprising: an elongated, flexible pole having first and second ends, the pole movable from a first set position to a second alert position in response to an increase in tension in the fishing line; a switch interconnecting the indicator to a power source, the switch having first and second terminals normally biased toward a closed position such that the first terminal is in contact with the second terminal; a flag affixed to the elongated pole for use as an insulator between the terminals of the switch when the pole is in the set position; and means for removing the flag from between the terminals of the switch in response to an increase in tension in the fishing line.
Claim 3
Independent Claim
146 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: a witch interconnecting the indicator to a power source, the switch having first and second terminals normally biased toward a closed position wherein the first terminal is in contact with the second terminal; an elongated flexible pole having first and second ends, the pole movable from a first set position to a second, alert position in response to an increase in tension in the fishing line; a flag affixed to the elongated pole of the tip-up, the flag placed between the first and second terminals of the switch such that the first and second terminals are not in contact; and means for removing the flag from between the terminals in response to an increase in tension in the fishing line.
Claim 4
Independent Claim
146 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: a witch interconnecting the indicator to a power source, the switch having first and second terminals normally biased toward a closed position wherein the first terminal is in contact with the second terminal; an elongated flexible pole having first and second ends, the pole movable from a first set position to a second, alert position in response to an increase in tension in the fishing line; a flag affixed to the elongated pole of the tip-up, the flag placed between the first and second terminals of the switch such that the first and second terminals are not in contact; and means for removing the flag from between the terminals in response to an increase in tension in the fishing line.
Claim 5
Independent Claim
110 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: a switch interconnecting the visual indicator to a power source, the switch having first and second terminals normally biased toward a closed position when the first terminal is in contact with the second terminal; a section of fishing line placed between the first and second terminals of the switch such that the first and second terminals are not in contact; and means for removing the section of fishing line from between the terminals in response to an increase in tension in the fishing line.
Claim 6
Independent Claim
110 words
A device for activating an audible or visual indicator on an ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: a switch interconnecting the visual indicator to a power source, the switch having first and second terminals normally biased toward a closed position when the first terminal is in contact with the second terminal; a section of fishing line placed between the first and second terminals of the switch such that the first and second terminals are not in contact; and means for removing the section of fishing line from between the terminals in response to an increase in tension in the fishing line.
Claim 7
Independent Claim
110 words
A method for activating an audible or visual indicator on the ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: providing a switch to interconnect the audible or visual indicator to a power source, the switch having first and second terminals normally biased toward a closed position such that the first terminal is in contact with the second terminal; inserting a section of fishing line between the terminals of the switch such that the first and second terminals are not in contact; and removing a section of fishing line from between the terminals in response to an increase of tension in the fishing line.
Claim 8
Independent Claim
110 words
A method for activating an audible or visual indicator on the ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: providing a switch to interconnect the audible or visual indicator to a power source, the switch having first and second terminals normally biased toward a closed position such that the first terminal is in contact with the second terminal; inserting a section of fishing line between the terminals of the switch such that the first and second terminals are not in contact; and removing a section of fishing line from between the terminals in response to an increase of tension in the fishing line.
Claim 9
Dependent Claim
14 words
A method of claim 4 wherein the section of fishing line is an insulator.
Claim 10
Independent Claim
150 words
A method for activating an audible or visual indicator on an ice fishing tip-up having a spool and a fishing line wound on the spool, comprising: providing a switch to interconnect the audible or visual indicator to a power source, the switch having first and second terminals normally biased toward a closed position such that the first terminal is in contact with the second terminal; providing an elongated flexible pole having a first and second ends, the pole movable from a first set position to a second alert position in response to an increase in tension in the fishing line; affixing a flag to the elongated pole; placing the flag between the terminals of the switch as an insulator such that the first and second terminals are not in electrical contact; and removing the flag from between the terminals in response to an increase in tension in the fishing line.
