An ice fish house base has at least two skis, each coupled through at least two pivotal arms to an ice house base. The pivotal arms are pivotal between an elevated position and a lowered minimum position. The lowered position is stable when the ice house base comes into solid contact with the ground, thereby limiting maximum rotation in this ice-house-base-lowered position. In the upward position, a rotational pivotal arm stop prevents the pivotal arms from rotating further, so that the separation between ice house base and skis is just less than maximum...
1. An ice fish house base and expansion lever, comprising: a first ski and a second ski;a first pair of arms pivotally coupled between and to each of said first ski and said ice house base;a second pair of arms pivotally coupled between and to each of said second ski and said ice house base;a link between said first pair of arms and said second pair of arms transmitting a rotary movement of said first pair of arms relative to said ice house base from said first pair of arms to said second pair of arms to thereby cause a rotary movement of said second pai...
