Apparatus for constructing a snow shelter

A portable apparatus for constructing a shelter of snow or ice for protection of users against the environment, said apparatus comprises:

• a) a slip form, said slip form including:
• 1. a first side having inner and outer surfaces and first and second lateral edges;
• 2. a second side having inner and outer surfaces, said inner surface of said second side being positioned in a parallel and opposing relationship with said inner surface of said first side thereby creating a cavity in between and further having first and second lateral edges corresponding to the first and second lateral edges of the first side;
• and
• 3. a third side having a first edge, a second edge, and a bottom edge, said third side being positioned perpendicular to said first and second sides, said first edge removably connected to the first lateral edge of said first side and said second edge removably connected to the corresponding lateral edge of said second side;
• and
• b) an elongated slip form positioning means having first and second ends, the first end of the positioning means being pivotally connected to an anchor means secured so as to locate the center of the shelter and the second end attached to the outside surface of either the first or second side by a removable swivel means which allows connection and disconnection and pivotal and rotational movement between the slip form positioning means and the slip form.

A portable apparatus for constructing a shelter of snow or ice for protection of users against the environment, said apparatus comprising a slip form positioning means and a slip form for forming insitu building blocks of snow or ice, which building blocks are used to construct the walls of said shelter, said slip form further comprises:

• a) a first side having an inner and outer surface which are vertically oriented and first and second lateral edges;
• b) a second side having an inner and outer surface which are vertically oriented, said inner surface of said second side being positioned in a parallel and opposing relationship with said inner surface of said first side thereby creating a cavity inbetween, and further having lateral edges corresponding to the first and second lateral edges of the first side;
• c) a third side having a first vertical edge, a second vertical edge, and a bottom edge, said third side being positioned perpendicular to said first and second sides, said first vertical edge removably connected to the first lateral edge of said first side and second vertical edge removably connected to the corresponding lateral edge of said second side;
• and
• d) the bottom edge of the third side of the slip form further includes a guide means for guiding the movement of said slip form when it is moved to a new position, said guide means further comprising a ski having a longitudinal axis and a keel, said ski being arranged perpendicular to said third side, said keel being positioned at an angle with the axis of the ski to define an arc through which said slip form can be moved.
