Definitions

  • the invention relates to a component for construction models, in particular construction toys, according to the preamble of patent claim 1.
  • Components of this type are known, for example, from Swiss Patent No. 362,354, in which a wall is provided on one side with at least one row of coupling pins and on the other side with mating coupling elements for connection to coupling pins of an adjacent component.
  • Swiss Patent No. 455 606 it is also known that at least some of the coupling pins have electrically conductive surfaces or that electrically conductive contact elements are arranged on the side of the wall provided with the counter-coupling elements, which are intended for the mechanical coupling of two components to make electrical contact with the conductive surfaces of the adjacent coupled component.
  • the object of the invention is to provide a component of the type mentioned, the electrical contact means of which can be adapted to the coupling pins or mating coupling elements of each component system, which can also be combined as desired with the contact-free components of the same component system and whose contacting with a similar one The position of the component can be clearly defined.
  • the component has the features stated in the characterizing part of patent claim 1.
  • the surfaces of the coupling pins have electrically insulating and electrically conductive areas, when coupling the component with a further contact element with a contact element parallel to the row of its coupling pins, it can be achieved that in certain relative positions of the two components an electrical connection between the conductive coupling pins one component and the contact element of the other component or the conductive regions of its coupling pin connected to the contact element are produced or not.
  • the electrically conductive regions of the coupling pins are preferably located at least on side surfaces of the coupling pins which are perpendicular to a common plane of the coupling pins, the contact element having a conductive contact surface which extends in the direction of the row of coupling pins and is perpendicular to the common plane mentioned.
  • the electrically conductive areas on the coupling pins extend over an angular range of more than 90 ° and less than 270 ° around the longitudinal axes of the coupling pins and are configured and arranged identically for the coupling pins of the same row. In this way, in the case of two components that are coupled to one another, a positionally clearly defined contact between the two components is achieved, i.e. Contact is made in a certain mutual position, but not in a position rotated by 90 °.
  • the components have two rows of coupling pins lying next to one another in pairs, the conductive surfaces of which lie in one row in an angular range which is rotated by 180 ° with respect to that of the other row, and if the side of the components provided with the counter-coupling elements each has a contact strip for each of the two rows of coupling pins, the contact strips being electrically conductively connected to the conductive surfaces of the assigned rows of coupling pins, so regardless of how the two components are coupled to one another, the same assignment of electrical connections is always obtained, that is achieved a polarity correct connection.
  • Each contact element is preferably designed as an electrically conductive contact rail, which extends along the associated row of coupling pins on the opposite side thereof and is connected to the electrically conductive areas of the coupling pins of this row.
  • a conductive contact rail can be arranged either along two parallel side walls of the hollow body or on both sides and along a center line having the same spacing from two parallel side walls of the hollow body .
  • the toy component shown in FIGS. 1 to 3 has, in a manner known per se, for example, from CH-PS 362 354, a box-shaped hollow body 1 consisting of an electrically insulating plastic material with end walls 2, side walls 3 and a perpendicular to the end and side walls Bottom wall 4.
  • the component On the outside of the bottom wall 4, the component has cylindrical coupling pins 5.
  • counter-coupling elements acting in a clamping manner are formed, which consist of cylindrical tubes 6 projecting from the bottom wall 4 of the hollow body 1.
  • the component has two rows of six coupling pins 5 lying in pairs next to one another and five mating coupling tubes 6.
  • the coupling pins 5 of one component become in the overlapping parts of the two Components each clamped between two mating coupling tubes 6 and a side wall 3 or between a mating coupling tube 6, a side wall 3 and an end wall 2.
  • This fixed, but detachable, mechanical connection type does not need to be discussed any further, since it is sufficiently known.
  • the side surfaces or lateral surfaces of the coupling pins 5 have an electrically conductive surface in the form of a metallic layer 7. 1 and 3, these conductive layers are shown with thick, solid lines, in Fig. 2 with thick, dashed lines, since they are not visible.
  • the conductive layers 7 do not extend over the entire circumference of the coupling pin 5, but only over an angular range of approximately 180 °. This angular range can also be smaller or larger, namely on the one hand up to almost 90 ° and on the other hand up to almost 270 °. It can also be seen from FIG. 1 that an imaginary parting plane between the part provided with the conductive layer 7 and the remaining insulating part 8 of each coupling pin 5 forms an angle of approximately 45 ° with respect to the side walls 3.
  • the conductive layers 7 together with the insulating surface parts 8 form a smooth cylindrical jacket, so that the present coupling pins 5 completely match the shape and dimensions of the normal, fully insulating coupling pins of similar components.
  • FIGS. 1 to 3 an electrically conductive, metallic, strip-shaped strip 9 is arranged along both side walls 3 in the interior of the hollow body, which strip is referred to below as contact strip. 2 and 3, these contact strips 9 are shown with thick, solid lines, in FIG. 1 with thick dashed lines, since they are not visible.
  • Each longitudinal row of coupling pins 5 is accordingly assigned a contact strip 9, which is also electrically conductively connected to all conductive layers 7 of the coupling pins 5 of the row in question.
  • the side walls 3 have a thickness such that, together with the associated contact strip 9 (cf. FIG. 3), they form a wall thickness which is the same as that of the normal, fully insulating side walls of the same components.
  • the conductive layers 7 consist of bent sheet metal pieces, which are electrically and mechanically firmly connected to the associated band-shaped contact strip 9.
  • the conductive layers 7 and the contact strip 9 are preferably produced in one piece by cutting a sheet metal strip, the width of which is equal to the height of the component including the coupling pin 5, at corresponding points to a width corresponding to the height of the coupling pin 5 (FIG. 3). and the incised areas are bent out as shown in FIG. 4 and are stepped away from the remaining part of the sheet metal strip (FIG. 3). This can easily be achieved in one stamping operation.

  • the coupling pins 5 are shown translucently in the overlapping regions of the components 10 and 11. It can be seen that the one contact strip 9 of the component 10 comes into electrical contact with the conductive layer 7 of one of the coupling pins 5 of one row 13 of the component 11, but not with any conductive layer 7 'of a coupling pin 5 of the other row 14.
  • the toy component shown in FIGS. 5 and 6 also has a box-shaped hollow body 1 with end walls 2, side walls 3 and a bottom wall 4. However, the component has only a single row of cylindrical coupling pins 5 (FIG. 5) while in the interior of the hollow body 1 cylindrical pins 15 are formed on the bottom wall 4 as a counter-coupling element (FIG. 6).
  • each coupling pin 5 is composed of a metallic part 16 and an insulating part 17 formed in the bottom wall 4, the parts 16 and 17 being longitudinal a diametrical separation plane inclined at 45 ° to the side walls 3 and thus form a side surface of the coupling pin 5 that is conductive over 180 ° and insulating over 180 °.
  • the metallic parts 16 penetrate the bottom wall 4 (FIG. 6) and are connected to the one leg 18 of a metallic angle rail 19 resting against the bottom wall 4, e.g. soldered.
  • the other leg 20 of the angle rail 19 forms a contact strip extending along the one side wall 3.
  • the contact member consisting of the angular rail 19 with the legs 18 and 20 and the metallic parts 16 of the coupling pins fastened to the leg 18 is shown in FIG. 7.

  • the contact strip 20 of the component 21 comes into electrical contact with the metallic part 16 of the coupling pin 5 of the component 22, on which the component 21 has been placed.
  • FIGS. 10 and 11 a further toy component is shown, the hollow body 1 of which differs from that of FIGS. 1 and 2 in that in the interior of the hollow body two parallel longitudinal walls 24 as mating coupling elements for the coupling pins 5, which are present in two rows, are formed on the inner surface of the bottom wall 4 and the end walls 2.
