Abstract: A toy building set of the type having elements with projections on one surface for engagement with apertures on a surface of another element is provided with detection elements for receiving light energy reflected from bar code elements. The detection elements and the bar code elements are also provided with at least one of the projections or apertures on a surface thereof to permit those elements to be mechanically coupled to other elements of the building set.

Abstract: A toy construction set may utilize blocks with electrical connections, this block receives electrical power, outputs energy in the electromagnetic spectrum, receives reflected energy and outputs a result to be utilized elsewhere in the toy assembly. Though it has connectors to attach it to other like blocks, it has a bearing shaft to enable an anemometer (FIG. 5) or a tachometer. It may sense bar codes and enable an assembled vehicle to accept trackway commands.

Abstract: A wheel bearing, in particular for toy vehicles, which are usually subjected to strong overloads, is characterized in that, in the vicinity of each end, the wheel axle (10, not shown in FIG. 2) has both a bearing face (14, 15) with a relatively small radius of curvature and a bearing face (12, 13) with a relatively large radius of curvature substantially corresponding to the radius of the axle. The bearings with the small radius of curvature (14, 15) are elastically resilient, the bearing faces with the relatively small radius of curvature being provided in bearing plates (2, 3) which are connected with a vehicle portion (1) via elastic connecting members (4, 5). When the toy vehicle is overloaded, the axle is supported in the large bearings (12, 13) so that the small bearings (14, 15), having a very small friction under normal operating conditions, are not damaged.

Abstract: A toy building block having on one face thereof at least one row of mechanical coupling pins and opposite thereto mechanical counter-coupling tubes for coupling said toy building block to a similar toy building block either with the row of said coupling pins parallel to a corresponding row of coupling pins of said similar block or perpendicular to said corresponding row. The toy building block includes first and second current paths connected to first and second contact areas respectively designed to establish electrical connection with first and second contact areas in a similar block. The first and second contact areas are disposed in first and second angular sectors about adjacent coupling pins. The angular sectors are offset from each other and do not overlap regardless of whether the building block row of coupling pins is parallel or perpendicular to the row of coupling pins of the similar block.

Abstract: In a building element of the special type which in addition to being provided with coupling means for mechanical intercoupling of the building blocks-contains current-carrying components placed in the electrically insulated building block (2). There are provided at least two current-carrying components (3, 4) with respective contact areas which are mutually co-axially positioned. Hereby building blocks (2) of this type can be intercoupled mechanically while establishing electrical connection between the respective current rails (3, 4) in the cooperating building elements, without any risk of short circuiting between the two current-carrying components, no matter how the building blocks are intercoupled mechanically.

Abstract: A wheel is partly closed at one side by a hub cap (1) continuous with the rim (6) and is designed to receive an axle from the opposite side. According to the invention, the hub of the wheel consists of a plurality of ribs (14-17) which serve as bearing faces for the axle and whose geometric, axial elongations clear a plurality of spokes (2-5) forming the connection of the hub cap to the rim (6). This enables injection moulding in one operation with the simultaneous provision of an inside cavity behind the hub cap to receive a radially resilient and projecting bead (11) at the end of the axle.

Abstract: A connecting member comprising an elastically deformable, tubular plug (1) slitted at the ends for interconnecting pairs of building components (9a,9b), which have coupling holes (8a,8b) to receive the ends of the connecting member, has apertures (3) in the plug wall between the slits (2), and the plug wall is formed with lengthwise extending clamping wedges (4) between the apertures (3), said clamping wedges having inclined faces which slope towards the ends of the connecting member and causing the connecting member to be compressed at the center and be expanded at the ends when it is pressed into a pair of co-axial holes in adjacent building components. The connecting member may in particular be formed with an annular flange (5) and end beads (6a,6b) which fit in corresponding annular grooves (7) in a pair of adjacent components (9a,9b).

Abstract: An electrical machines constructional set comprises a base plate for mounting a pair of stator elements and including bearing apertures for a rotor shaft and a plurality of coupling holes for magnets or electro-magnets provided with complementary coupling prongs. A disk-shaped rotor element also has coupling holes, the number and arrangement of the coupling holes in the rotor element being the same as in the stator element so that parts are interchangeable to construct an electrical motor. A pair of circular disk elements made of soft iron having holes complementary to those of the stator and rotor elements are mounted on each end of the shaft to concentrate the magnetic flux provided by the magnetic elements.

Abstract: A track for toy trains is made by detachably connecting a plurality of rail elements having lengthwise extending rail-forming ribs with tie elements provided with connecting members adapted to be clamped into cavities in the bottom of the rails adjacent the ends thereof, so as to provide a sort of snap-locking device, including :in the rails: a lengthwise extending cavity (12) in the bottom of the rails defined by side walls (15) and end walls (16).

Abstract: A connector for converting a reciprocating movement of one element of a toy building set into a rotating movement of another element by means of a swingable connecting rod interconnecting the two elements.The connector comprises a first tubular member pivotally mounted in a bearing housing arranged for reciprocal movement between a pair of guides, and a second tubular member disposed at a right angle relatively to the first tubular member and adapted to receive one end of the connecting rod, the other end of which being swingably mounted on a rotating disc by means of a similar connector.
