Definitions

  • An erection kit includes a plurality of building blocks having on the respective surfaces thereof either elongated undercut open-ended grooves at least one of which is provided with a wider portion s0 dimensioned as to receive a coupling head, or undercut coupling heads receivable in these grooves through the open ends or through the wider portion of the respective groove.
  • An electrically conductive contact element for conducting electrical energy between a source and a user device which includes a first portion configurated so as to be receivable in the respective grooves and a section on the first portion which is receivable in the wider portion of such groove to thereby prevent the first portion from being shifted in the groove, and a connected second portion which projects from an open end of the groove when the first portion is received therein.
  • kits are of particular interest to a child if the kit enables the child to produce true-to-life constructions.
  • Particularly movable constructions such as vehicles or the like, stimulate the imagination of children playing with this type of toy.
  • a vehicle that is a user device, is to be capable of moving it must be provided with motive power. This is usually done by providing an electromotor.
  • an object of the present invention to provide, in an erecting kit of the type under d scussion, an electrically conductive contact element for conducting electrical energy between a source and a user device which is considerably simpler and more versatile than what is presently known in this field.
  • the contact element according to the present invention is not to influence, or to influence only to the minimum possible extent, the versatility of connection between the structural elements of the erecting kit.
  • this contact element is to provide reliable electrical contact with the source even. if the spacing between the element and the source changes.
  • an erection kit of the type including a plurality of structural elements each having a plurality of surfaces, at least some of such surfaces of at least some elements being provided with undercut projecting coupling head and at least some surfaces of at least some elements being provided with complementarily undercut open-ended grooves of which at least one on each element so provided includes an insertion aperture having a cross-section so dimensioned as to permit insertion of a coupling head normal to the elongation of the groove, the improvement which consists in the provision of an electrically conductive contact element for conducting electrical energy between a source and a user device.
  • My novel contact element includes a first portion configurated so as to be receivable in the groove having the insertion aperture and this first portion includes a section receivable in this aperture.
  • a connected second portion projects from an open end of the groove when the first portion is received therein.
  • FIG. 1 is a somewhat diagrammatic illustration showing a structural element With the electrically conductive element according to the present invention secured thereto;
  • FIG. 2 is a longitudinal section through the electrically conductive element of the present invention.
  • FIG. 1 illustrates a structural element in form of a building block or the like, which is provided on some of its surfaces with longitudinally extending undercut grooves 2. Adjacent the end face 3 these grooves are pro vided with inserting apertures 4 so dimensioned that an undercut coupling head, configurated complementary to the cross-sectional configuration of the grooves 2, and provided on another building block, can be inserted through these apertures 4- into the grooves 2 so as to connect the (nonillustrated) other building block with the one shown.
  • an undercut coupling head configurated complementary to the cross-sectional configuration of the grooves 2, and provided on another building block
  • the end face 3 is also provided with an undercut groove corresponding to the grooves '2 and having open ends communicating with the inserting apertures 4 of two of the grooves 2, as shown.
  • the novel electrically conductive element 6 is inserted into the groove 5'.
  • This element 6 is shown in detail in FIG. 2 where it will be seen to consist of a contact portion 7 and a securing or mounting portion 8.
  • the latter consists of two sections, identified with reference numerals 9 and 10.
  • the cross-sectional configuration of the section 9 corresponds to the cross-sectional configuration of the undercut grooves 2 and 5, whereas the cross-sectional configuration of the section 10 corresponds to the cross-sectional configuration of the wider portion or inserting apertures 4 provided in th%e grooves.
  • a transverse bore 11 is provided in the section 9 so that a connector, a cable or the like can be secured to the element 6 by insertion into the bore 11.
  • This lbore may extend transversely to the longitudinal axis of the element 6, or it may extend longitudinally of the latter.
  • the portion 8 is provided with a longitudinal bore or recess 12 into which the contact portion 7 is telescoped.
  • An expansion spring 13 is also received in the bore 12 urging the portions 7 and 8 apart to their maximum extended position, a suitable abutment being provided to prevent the portion 7 from completely moving out of the bore 10'.
  • Any electrically conductive material is suitable for the construction of the element 6.
  • the element 6 may be inserted into one of the grooves 2, if desired, rather than into the groove 5. 'In this case it may for instance be used for electrically connecting shafts or axles received in similar grooves provided in a plurality of longitudinally connected ones of the structural elements, whose grooves 2 carrying these shafts or axles are longitudinally aligned with one another.
  • the contact portion 7 of the element 6 projects only beyond one surface, either a lateral surface or an end face of the respective structural element in which it is secured, so that other structural elements may be connected with this one structural element at all others of the surfaces thereof Without interference by the element 6.
  • the telescopic construction illustrated in the drawing is not absolutely necessary and that the portions 7 and *8 could also be of one-piece construction. However, I currently prefer the construction as it is illustrated in the drawing because of its greater versatility.
  • an erection kit of the type including a plurality of structural elements each having a plurality of surfaces, at least some of such surfaces of at least some elements being provided with undercut projecting coupling heads and at least some surfaces of at least some elements being provided with complementarily undercut open-ended grooves of which at least one on each element so provided includes an insertion aperture having a cross-section so dimensioned as to permit insertion of a coupling head normal to the elongation of the groove and registering with said groove to form a passage therewith, the improvernent consisting in the provision of an electrically conductive contact element having means for conducting electrical energy between a source and a user device, including a first portion configurated so as to be receivable in said one groove and having a section of a size receivable in said aperture 'but not in said one groove, and a connected second portion projecting from an open end of said passage when said first portion is received therein.
  • said one portion being telescopically movable with reference to said other portion between a fully projecting position and a partly projecting position; and further comprising biasing means urging said one portion to said fully projecting position.
  • said biasing means comprising an expansion spring received in said other portion and abutting against an inner end of said one portion.
  • both of said portions being. of substantially rod-shaped configuration.
