Three-dimensional puzzle

Clamping device

Electronic spatial logical toy containing movable and/or rotatable

The invention relates to an aircraft structure to make possible take-off and landing on a pilot's feet. The aircraft structure according to the invention can be regarded as a category between kite-shaped aircraft structures and light structures. The gist of the aircraft structure of the invention consists in providing freely supported or outerly reinforced wings (12) adapted to be moved by a pilot (15) actuated mechanism, in their own plane during flight.

Aircraft structure for take-off and landing on a pilot's feet

An array of plate-like elements is retained by endless filaments looped on the elements to form migrating hinges between individual elements and other elements adjoining same. Grooves are formed in the surfaces of each plate, the grooves being in two groups, with the members of each group being mutually parallel, and the grooves of each surface being in overlying registration. The filaments lie within the grooves in a selected pattern, with filaments forming anchor points at plate sides at which the filament wraps around the side of the plate to enter a groove from the other group of grooves on the opposite side of the plate, and hinge points at plate sides where the filament passes from one plate to an abutting plate, proceeding from one surface to the opposite surface in doing so. Manipulation of the resulting array allows two such plates to rotate mutually about an axis defined by hinge points lying on their abutting sides. Further manipulation allows the hinge between such plates to migrate to one of two other sides on such plates.

Logical toy

The invention concerns a shiftable element logical puzzle in the form of a cylindrical body comprised of an assembly of sector shaped cylinder forming elements, said elements forming two identical cylinder halves in the form of upper and lower tiers of six elements each, three of said elements in each tier being identical to each other, but different from the remaining elements, and means joining said elements together to form said cylindrical body and enabling various groupigs of six elements, three from each tier, to rotate relative to the remaining three identical elements about three axes passing through the cylinder body axis but perpendicular thereto.

Shiftable element puzzle

A toy for constructing different geometric shapes has a plurality of hollow prismatic identical toy elements having a triangular base and quadratic faces. The elements are connected at two faces to adjoining elements by spring biased headed pins passing through aligned throughbores in the centers of the two faces to permit relative rotation about axis normal to the two faces. The elements are maintained in any one of a plurality of angular orientations by projections on one of the two faces of each element and depressions in the other face of each toy element.

Toy with turnable elements for forming geometric shapes

A spatial logical toy is formed from a total of eighteen toy elements, out of which two sets of eight identical toy elements two connecting elements are provided. The elements of the two sets have cam members with hollows with spherical convex or concave surfaces in-between. The elements are connected by the aid of the cams and the two remaining centrally positioned substantially identical connecting elements each having a T-shape cross-section and when assembled the toy is in the form of a regular or an irregular solid. Fixation is performed by one single screw passing through bores in the connecting elements. In such a manner the toy elements forming the lateral faces of the spatial logical toy can be rotated along the spatial axes and by yielding several variation possibilities the toy is well suitable for stimulating logical thinking activity.

Spatial logical toy

A spatial logical toy in form of a regular geometrical solid, the toy-elements of which are assembled so that halves of the logical toy taken along any axis can be rotated in any direction of any of the spatial axes of the body in relation to the other half. The toy comprises a total of eight toy-elements, seven of which are identically shaped and are designed in such a way, that the corners are directed to the geometrical center of the body forming the spatial logical toy and are formed as profiles with a spherical surface. In the assembled state, between the profiles a hollow connecting element with a spherical surface on the upper part and having a T-shaped cross section is arranged. At the bottom of the hollow part of the connecting elements is a bore and a threaded pivot enclosed by a spring reaching to the bottom of the recess is passed through the bore and the threaded end of the pivot is screwed into a part of the eight toy-element which is directed to the geometrical center of the solid. The eighth toy-element is formed with a spherical cam and the spatial axes passing through the corner of the eight toy-element is directed to the inside of the body and through the surface center of the body.
