Abstract
A fin plug (10) for installation in a water craft, said fin plug (10) including: a first open cavity (20) adapted to receive a base portion (15) of a water craft fin (50); and, a resilient biasing rod (30) and a protruding member (35) cooperating with the biasing rod, said protruding member being adapted to abut the base portion (15) of said fin (50) when received in said first open cavity (20); wherein said biasing rod and protruding member are adapted to apply a force to the base portion of said fin to inhibit removal of said fin from said first open cavity.
Claims26
A water craft fin to be removably secured to a water craft fin plug having distinct front and rear open cavities and a bridge section therebetween,
- each of the front open cavity and the rear open cavity of the fin plug having a front end, a rear end and opposed side surfaces;
- the front open cavity of the fin plug having a front cavity fin engagement means comprising a protrusion in the front end of the front open cavity and a first recess between the protrusion and a base surface of the front open cavity;
- and
- the rear open cavity of the fin plug having a resiliently protruding ring-shaped member extending into the rear open cavity from a side surface of the rear open cavity;
- the water craft fin comprising:
- a base portion having a front tab and a rear tab adapted to be received in the front open cavity and rear open cavity respectively;
- the front tab includes a nose section at a front portion of the tab which is adapted to be received in the first recess and retained by the front cavity fin engagement means;
- and
- the rear tab includes a side surface at least partially recessed, adapted to at least partially receive the resiliently protruding ring-shaped member of the rear cavity;
- the rear tab includes a beveled or radiused surface starting from a lowermost bottom of the rear tab and extending towards the side surface, wherein the beveled or radiused surface is adapted to engage with the resiliently protruding ring-shaped member before the recess of the side surface engages with the resiliently protruding ring-shaped member when the fin is inserted into the fin plug;
- such that the fin is removably secured to the fin plug by the fin engagement means and the resiliently protruding ring-shaped member.
A water craft fin to be removably secured to a water craft fin plug having distinct front and rear open cavities and a bridge section therebetween,
- each of the front open cavity and the rear open cavity of the fin plug having a front end, a rear end and opposed side surfaces;
- the front open cavity of the fin plug having a front cavity fin engagement means comprising a protrusion in the front end of the front open cavity and a first recess between the protrusion and a base surface of the front open cavity;
- and
- the rear open cavity of the fin plug having a resiliently protruding ring-shaped member extending into the rear open cavity from a side surface of the rear open cavity;
- the water craft fin comprising:
- a base portion having a front tab and a rear tab adapted to be received in the front open cavity and rear open cavity respectively;
- the front tab includes a nose section at a front portion of the tab which is adapted to be received in the first recess and retained by the front cavity fin engagement means;
- and
- the rear tab includes a side surface at least partially recessed, adapted to at least partially receive the resiliently protruding ring-shaped member of the rear cavity;
- the rear tab, between the partially recessed side surface and a lowermost bottom, has a cross-sectional thickness that is thicker towards the side surface compared with the lowermost bottom;
- such that the fin is removably secured to the fin plug by the fin engagement means and the resiliently protruding ring-shaped member.
A water craft fin to be removably secured to a water craft fin plug having distinct front and rear open cavities and a bridge section therebetween,
- each of the front open cavity and the rear open cavity of the fin plug having a front end, a rear end and opposed side surfaces;
- the front open cavity of the fin plug having a front cavity fin engagement means comprising a protrusion in the front end of the front open cavity and a first recess between the protrusion and a base surface of the front open cavity;
- and
- the rear open cavity of the fin plug having a resiliently protruding ring-shaped member extending into the rear open cavity from a side surface of the rear open cavity;
- the water craft fin comprising:
- a base portion having a front tab and a rear tab adapted to be received in the front open cavity and rear open cavity respectively;
- the front tab includes a nose section at a front portion of the tab which is adapted to be received in the first recess and retained by the front cavity fin engagement means;
- and
- the rear tab includes a side surface at least partially recessed, adapted to at least partially receive the resiliently protruding ring-shaped member of the rear cavity;
- a bottom of the rear tab has a beveled or radiused surface adapted to engage with the resiliently protruding ring member before the recessed side surface engages with the resiliently protruding ring-shaped member when the fin is inserted into the fin plug;
- such that the fin is removably secured to the fin plug by the fin engagement means and the resiliently protruding ring-shaped member.
