Method for sliding on grass slopes and a board assembly therefor

A board assembly for sliding on grass slopes, comprising in combination,

• a board having;
• essentially, a rectangular shape, with longitudinal and transversal axes of symmetry which intersect at the center of symmetry of said board;
• and an upper surface, a lower surface, a front and rear ends and a pair of lateral ends, said front and rear ends being curvilinear;
• and
• a retaining means including
• a pair of retaining frames, each having, essentially, a rectangular shape with a long axis of symmetry parallel to said transversal axis of symmetry and a short axis of symmetry coinciding with said longitudinal axis of symmetry;
• and
• a pair of parallel short elements parallel to said longitudinal axis of symmetry and a long element parallel to said transversal axis symmetry and proximate to said front and rear end, the former and the latter named elements being firmly secured to said lower surface;
• and
• a removable long element parallel to said long element and disposed near said transversal axis of symmetry and adapted to fit, with its opposite ends, by corner lap joints, in adjoining ends of said short elements, each said removable long element having a side, directed towards said transversal axis of symmetry, which is provided with a central recess;
• a retainer, fixed on the exterior top surface of each short, long and removable long elements, extends inwardly beyond internal edge of each of said named elements and provides a lip, and, thus a rectangular contour, which encompasses an open surface less than interior surface of said retaining frame is formed;
• and
• locking means for fixing in position or dismantling simultaneously said removable long elements.

A board assembly for sliding on grass slopes, comprising, in combination

• a unitary board having essentially a rectangular shape with longitudinal and transversal axis of symmetry, an upper and lower surface, a front and rear end, and a pair of lateral ends, said front and rear ends being curvilinear, the transition between said upper and lower surfaces, along the contour of said unitary board, being rounded;
• a recess starting from said lower surface, having, in bottom view, an essentially rectangular shape and extending, basically over most of the area of said lower surface, the axes of symmetry of said recess coinciding with said longitudinal and transverse axes of said unitary board;
• a rectangular entrance slit in each lateral surface of said pair of lateral ends, starting from said recess and located centrally and parallel to said longitudinal axis of symmetry, said rectangular entrance slit including, at each end, an upper part of a corner lap joint;
• a pair of removable long elements, each of which being adapted to fit with its opposite ends into adjoining ends of opposed rectangular entrance slits and, thus, two cavities adaptable for capturing ice blocks are formed;
• and,
• a retainer is firmly attached on the exterior surface of each zone delimiting each of said cavities, to each side of the latter including said removable long element, said retainers extend inwardly beyond the edges of said cavity, to form a lip;
• and
• a locking device for tightening or slackening simultaneously said opposed removable long elements, said locking device being located between said removable long elements.

A method of sliding on grass slopes, using a board having an upper and lower surface and adaptable to use an ice block, comprises the following steps:

• providing the board,
• attaching to the lower surface of the board at least one ice block;
• putting the board on a grass slope;
• and
• riding the board.
