Abstract: The invention relates to a ground peg (10) which is made from a steel tube (11) and comprises an upper cylindrical section (12), a lower section (16) that tapers towards the bottom to form a tip (14), and an external thread (26) that extends along at least part of the lower section (16) and is formed from a continuous sheet metal strip (28) welded onto an external surface (32) of the ground peg (10) by means of a continuous or regularly interrupted fillet weld (34). The external thread (26) has a nearly constant pitch (S) and slope (a) relative to a longitudinal axis (40) of the ground peg (10) along the entire length of the external thread (26). The invention further relates to a method or producing such a ground peg (10).

Abstract: The invention relates to a floor anchor (10) made of steel pipe. The floor anchor comprises a hollow shaft segment (14) having an external thread (16) at least in segments, and a head segment adjacent to the shaft segment (14) and facing downward in the anchored state in the floor. The head segment (12) is designed as a drill head and comprises elements for removing earth.

Abstract: A game using tokens bearing a number (N>2) of N-valued attributes, by finding, among tokens in each player's possession alone or in combination with those on a common playing field, groups of N tokens whose attributes, suitably permuted, form lines spanning the N-dimensional cube of NN combinations, and to arrange the playing field to consist entirely of such groups and networks thereof.
