Abstract: A coupling element for releasable retention of an end of an elongate pull element has a cavity to receive said end. The pull element is formed with a constriction and the coupling element with a corresponding cavity. The pull element may be inserted unobstructedly and subsequently be locked by moving a movable portion, e.g. in the form of a hinged portion, into a locking position in which, in combination with the cavity, it establishes releasable locking of the pull element.

Abstract: constructional building set comprising gear boxes which are provided with guide grooves and shaft passages. The guide grooves and the shaft passages are constructed such that transmission elements can be inserted into the guide grooves from the outer side of the gear box in such a manner that the transmission elements are positioned in alignment with the shaft passages in the gear boxes. When the gear box additionally comprises means for releasable geometrical retention of the transmission elements in their position in alignment with the shaft passages after insertion of the transmission elements into the gear box, it is ensured that the shafts can be pulled out of the assembled gear structure without the transmission elements dropping out of the gear structure. This simplifies the mounting operation and makes it easier to use the gear structure as an assembled unit that can be used for different applications.

Abstract: A building set for a toy building comprising a number of building modules (1) which each defines a space, said building modules (1) being so designed that they may be stacked or arranged next to each other as desired for the construction of single- or multi-storey toy buildings, and having means (6,7) for releasably engaging with one or more wall elements (5) in the sides of the building modules (1) irrespectively of the mutual positioning of the building modules (1). Since the columns (3) support girders (4) which define the periphery of the top plane of the building modules, said girders (4) being so arranged that unimpeded access to the building module interior (1) is provided, it is now possible to construct toy buildings with more different plan arrangements compared to the prior art without impeding the access to the building module interiors.

Abstract: A toy element composed of a rolling body having a body surface, with at least four apertures provided in the body surface, and at least two movable members. Each of the members consists of a first and a second oppositely arranged element interconnected by a rigid rod. The first and second elements are aligned with the apertures of the body surface. Each of the members is movable within the rolling body between a first position where the first element is significantly protruding from the rolling body surface while the second element is less protruding from the rolling body surface, and a second position where the second element is substantially protruding from the rolling body surface while the first element is less protruding from the rolling body surface. Each member has a center line, and the center lines of all of the members intersect at a common intersection point.

Abstract: A stacking block system having stacking blocks which have a body part which is provided with coupling knobs with a mutual uniform modular distance on its upper surface and is downwardly provided with coupling means which are complementary with respect to the coupling knobs on the upper side and are adapted to be coupled with the coupling knobs. According to the invention, the blocks are additionally provided with one or more spacers downwardly, which are designed such that when two stacking blocks are stacked on top of each other, the body parts of the stacking blocks will be spaced from each other along their entire periphery. This provides a gripping edge or a gap between two blocks stacked so that it is particularly easy to grip the blocks when a stack of such blocks is to be separated.
