Abstract
Abstract An ice fishing tip-up including a tube having a sealed end and an open end and a stand for the tube to position it with the sealed end below the surface of the ice and with the open end projecting above the surface of the ice. A visual signal member is mounted inside the tube for movement between a nonsignaling position within the tube and a signaling position outside the tube. The sealed end of the tube is sealed by means of a cap member fitted over the end of the tube. A spring is connected to the signal member to bias it for movement from the nonsignaling to the signaling position. A reel with a fishing line is mounted adjacent the sealed end of the tube. A magnetic coupling is provided between the reel and the end of the signal member which coupling includes a pair of permanent magnets, one of which is mounted on the reel and the other of which is mounted on the end of the signal member. The magnets are movable to a holding position where they will be in alignment with each other on opposite sides of the cap member on the end of the tube. The magnets, when in such holding position, provide a magnetic force greater than the spring biasing force to thereby hold the signal member in its nonsignaling position. When the reel is moved in response to pull on the line by a fish, the reel will be rotated causing the magnets to separate and thereby release the signal member for movement to its signaling position. The vertical position of the reel with respect to the sealed end of the tube can be adjusted to thereby adjust the sensitivity of the magnetic coupling.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
356 words
An ice fishing tip-up, comprising: a stand means for positioning the tip-up on ice; a tube means having a sealed end which is sealed by a sealing means and an open end, said tube means connected to said stand means so that said sealed end is in a position below the surface of the ice when said stand is positioned thereon and said open end is projecting above the surface of the ice, said sealing means including a continuous, imperforate wall of water impervious material extending across the end of said tube means; a visual signal membEr mounted within said tube and movable in both directions between a nonsignaling position within said tube and a signaling position outside of said tube; spring means connected to said signal member to bias said signal member for movement from said nonsignaling position to said signaling position, said spring means exerting a biasing force in a direction of said movement of said signal member when said signal member is in said nonsignaling position; a reel means for accommodating a fishing line; a support means for supporting said reel means adjacent said sealed end of said tube means; a reel mounting means for rotatably mounting said reel means on said support means; magnetic coupling means including a pair of permanent magnets, one of said magnets mounted on said reel means for movement therewith and the other of said magnets mounted on the end of said signal member for movement therewith, said magnets being movable to a holding position wherein they will be in alignment with each other on opposite sides of said imperforate wall, said magnets when in said holding position providing a magnetic force greater than said spring biasing force to thereby hold said signal member in its nonsignaling position, said reel means when rotated causing said magnets to separate to thereby permit said signal member to move from its nonsignaling position to its signaling position under the bias of said spring means, said support means for said reel includes means for vertically adjusting said reel so that the spacing of said magnets when in holding position can be adjusted.
Claim 2
Dependent Claim
356 words
An ice fishing tip-up, comprising: a stand means for positioning the tip-up on ice; a tube means having a sealed end which is sealed by a sealing means and an open end, said tube means connected to said stand means so that said sealed end is in a position below the surface of the ice when said stand is positioned thereon and said open end is projecting above the surface of the ice, said sealing means including a continuous, imperforate wall of water impervious material extending across the end of said tube means; a visual signal membEr mounted within said tube and movable in both directions between a nonsignaling position within said tube and a signaling position outside of said tube; spring means connected to said signal member to bias said signal member for movement from said nonsignaling position to said signaling position, said spring means exerting a biasing force in a direction of said movement of said signal member when said signal member is in said nonsignaling position; a reel means for accommodating a fishing line; a support means for supporting said reel means adjacent said sealed end of said tube means; a reel mounting means for rotatably mounting said reel means on said support means; magnetic coupling means including a pair of permanent magnets, one of said magnets mounted on said reel means for movement therewith and the other of said magnets mounted on the end of said signal member for movement therewith, said magnets being movable to a holding position wherein they will be in alignment with each other on opposite sides of said imperforate wall, said magnets when in said holding position providing a magnetic force greater than said spring biasing force to thereby hold said signal member in its nonsignaling position, said reel means when rotated causing said magnets to separate to thereby permit said signal member to move from its nonsignaling position to its signaling position under the bias of said spring means, said support means for said reel includes means for vertically adjusting said reel so that the spacing of said magnets when in holding position can be adjusted.
Claim 3
Dependent Claim
54 words
The combination according to claim 1 in which said sealing means at the sealed end of said tube means is comprised of a cap member fitted over the end of said tube means with said support means for supporting said reel comprising a depending bracket member which is made integral with said cap member.
Claim 4
Dependent Claim
53 words
The combination according to claim 2 in which said reel support means includes a shaft member on which said reel is rotatably mounted, said bracket member having a vertically extending slot therein in which said shaft is adjustably mounted to facilitate vertical adjustment of said reel means with respect to said tube means.
Claim 5
Dependent Claim
33 words
The combination according to claim 3 in which said shaft member is made of plastic material and includes an integrally molded spacer collar thereon located between said bracket member and said reel means.
Claim 6
Dependent Claim
86 words
The combination according to claim 1 in which said spring means is comprised of a tension spring fastened at one end to the lower end of said signal member and fastened at the other end to a collar member which is slidably mounted on said signal member, said spring means further including a stop member on the inside of said tube means adapted to engage said collar member when said signal member is moved to its nonsignaling position to thereby place said tension spring under tension.
