Abstract: A toy building set comprising a number of toy building elements and an overload-safe linear actuator having a center axis and with two spindle parts comprising a first spindle part with an internal thread arranged concentrically to the center axis, and a second spindle part with an external thread screwed into the internal thread on the first spindle part, and wherein the thread on the one spindle is at least twice as long as the thread on the second spindle part. One of the spindle parts being provided with a slot extending through the spindle part longitudinally of the thread configured on the spindle part and essentially along the entire thread, it is accomplished that it is easy to adjust the length of the actuator by pulling or pressing the two spindle parts together or away from each other.

Abstract: A toy building set comprising at least one building element (6) having a surface on which at least two coupling N studs (8) are provided that extend from the surface, and wherein those coupling studs are configured in a pattern by which there is a mutually fixed distance between adjacent coupling studs, and wherein the toy building set further comprises a perforator (1), said perforator comprising means for punching material from a sheet element configured from a thin material such as a sheet of eg paper, plastics or fabric, in such a manner that the perforator is capable of punching a hole in the sheet, which hole has such expanse that one or more coupling studs can be introduced into the punched hole.
