Definitions

  • Registering apertures are provided in both elements,
  • An elongated connecting member extends through both of the apertures and is tumable therein. It has a head portion which engages the second surface of one of elements and a free end portion provided with projections which are receivable in response to turning of the connecting member in corresponding recesses provided in the inner circumferential surface of the aperture in the other element or in the second surface of the other element. Thereby, the elements are connected against separation but can be turned with reference to one another.
  • the present invention relates generally to toy assembly kits, and more particularly to a connecting arrangement for use in a toy assembly kit. Still more specifically the invention relates to a releasable connecting arrangement for connecting two elements of a toy assembly kit with one another in such a manner that they can be pivoted with reference to each other in a plane common to them.
  • a more particular object of the invention is to provide a connecting arrangement of the type under discussion which is not possessed of these disadvantages.
  • Still a further object of the invention is to provide such a connecting arrangement which is to be not only simple, but also releasable so that the connected elements can readily be separated again whenever this is desired.
  • a concomitant object of the invention is to provide such a connecting arrangement which permits displacement of the connected elements with'reference to one another in a common plane but guarantees that no undesired disconnection will take place in response to such displacement.
  • one feature of the invention resides in a connecting arrangement for use in a toy assembly kit which, briefly stated, comprises a first and a second element which are to be connected, these elements having respective juxtaposed first surfaces, respective second surfaces facing away from one another, and respective registering apertures each extending from the first to the second surface of the element.
  • An elongated connecting member extends through both of the apertures tumable therein and includes a head portion engaging the second surface of the first element and a free end portion arrestingly engaging the second element in a sense preventing unintentional separation of the elements in direction lengthwise of the connecting member.
  • one of the members namely the one in whose aperture the free end portion is not located is capable of pivoting displacement with reference to the other member.
  • a child Using members connected in this manner for erecting a structure, for instance the skeleton of a building, a child will at once realize that to achieve the necessary rigidity of the structure it is imperative to provide cross-braces or the like.
  • the members Despite the pivoting ability imparted to the members connected in this manner with the novel connecting arrangement, the members have no play in direction lengthwise of the pivot axis so that there is no danger of "sagging of the erected structure.
  • the arresting engagement of the free end portion with the other structural element can be accomplished in various ways.
  • brief mating screw threads may be provided on the free end portion and in the aperture of the second structural element, and the arrangement can be such that the screw threads can be engaged and tightened with reference to one another to the maximum possible extent while still permitting movement of the first structural element with reference to the second structural element.
  • a different and preferred possibility is to provide the free end portion with two projections preferably located diametrally opposite one another and to provide the inner circumferential surface bounding the aperture in the second structural element, or the second surface of the second structural element, with corresponding recesses in which the projections will enter when the connecting element is turned.
  • the latter possibility would require that the free end portion actually slightly projects beyond the second end face of the second member with the projections being located at that part of the end portion which is outside the aperture in this second member and projects beyond the second surface.
  • the structural element may be provided at its head portion with either a male or a female connecting portion, for instance an undercut coupling head or an undercut groove which can matingly engage with corresponding connection portions on other structural elements of the kit.
  • the juncture between the intermediate portion of the connecting member which extends between the free end portion and the head portion of the latter may be provided with diametrally oppositely located recesses so that the connecting member can be secured to the structural elements just mentioned and provided with the cooperating connecting portions so that by this means structural elements connected by the connecting member can be secured to other structural elements having the aforementioned connecting portions.
  • the diametrally opposite location of such recesses or cut-outs permits the sliding insertion of the connecting member into an undercut connecting member or into an undercut groove provided on such structural elements because the recesses or cutouts correspond to the undercut configuration of such a groove. If projections are provided on the free end portion as discussed before, they are not of any disadvantage in this connection.
  • the recesses are offset through 90 with reference to the projections and this makes it possible to use the projections visually for orienting the connecting member in proper manner for insertion into an undercut groove. For this purpose it is simply necessary that the projections extend in direction lengthwise of the groove which will then automatically indicate that the recesses are properly located.
  • the second element with which the free end portion and the projections, if there are any, co-operate is provided with an abutment which prevents excessive turning of the connecting member with reference to the second element.
  • This is particularly important if the projections project to such an extent from the free end portion that the apertures in both the first and the second member must be provided with longitudinally extending grooves through which the projections slide as the connecting member is introduced into the aligned apertures. Excessive turning of the connecting member could in such case cause the projections first to wedgingly engage the corresponding surfaces of the second member and then to move beyond the same and enter again into these longitudinal grooves which would evidently destroy the connection. Hence, the abutment.
  • the intermediate portion of the connecting member has a thickening extending from the head portion towards the free end portion and located in the aperture of the first member or element, namely the one closest to the head portion.
  • the length of the thickening should be such that it extends just slightly beyond the aperture towards the second member or element. The purpose of this is to prevent the two connected members or elements from being drawn into such tight frictional engagement-for instance because of improper tolerancesthat pivoting movement of the connecting elements relative to one another is impossible.
  • the free end portion may have a conically tapered tip to facilitate its insertion into the respective apertures.
  • the manner in which the free end portion is releasably connected with thesecond element may vary as already indicated.
  • the connecting member will be turned about its own longitudinal axis for effecting connection or disconnection.
  • the head portion of the connecting member may be provided with a recess capable of accommodating these coupling heads and turning can be very simply effected by inserting such a coupling head of another structural element into this recess and turning the structural element. This avoids the need for a tool and provides the equivalent of a tool in terms of convenience of operation.
  • the first element is of L-shaped cross section or of analogous cross section, then this is not possible any more because the structural element would be impeded either during insertion or during subsequent attempted tuming-by the upstanding arm of the L-shaped cross section, assuming that this arm extends upwardly away from the second element.
  • the height of the head portion correspond to the height of the upstanding arm, or possibly be slightly in excess of such height so that it is again possible to utilize the coupling head of another structural element for turning of the connecting member in the manner just described.
  • the head portion of the connecting member may also be provided with a transverse bore extending transversely of the axis about which the connecting member is to be turned.
  • the bore accepts shafts and this is particularly advantageous if the elements connected with this connecting arrangement comprise at least one L-shaped element of the type just outlined, because the shaft can be reliably joumalled in this manner, a possibility which heretofore was frequently impossible because of the relative thinness of the arms of such Lshaped members.
  • the head portion may be substantially V-shaped analogous to a wing nut, and its lower portion, that is a portion of the head portion located intermediate the intermediate portion and the wingshaped portion may be receivable in a depression provided in the second surface of the first element.
  • the head portion can be particularly readily engaged by the fingers of evena small child so that the connection and turning can be accomplished in a simple, efiortless manner without the use of additional tools or help.
  • FIG. 1 is a fragmentary sectional elevation showing a connecting arrangement according to the present invention
  • FIG. 2 is a view of the embodiment in FIG. 1 as seen in the direction of the arrow II;
  • FIG. 3 illustrates the connecting element according to the present invention in a further embodiment
  • FIG. 4 illustrates an additional embodiment of the invention in a view similar to FIG. 1;
  • FIG. 5 illustrates in partial section and yet another embodiment
  • FIG. 6 is a sectional elevation showing an additional embodiment
  • FIG. 7 is a fragmentary partly sectioned illustration showing still a further embodiment of the invention.
  • reference numeral 1 identifies an elongated connecting member of the arrangement according to the present invention. It is shown in FIGS. 1 and 2 as connecting two structural elements 2 and 3 with one another. These structural elements are provided with aligned apertures. Specifically the structural element 2 is provided with an aper ture 4 of stepped inner cross section (compare FIG. 1) and accommodates in this aperture 4 the head portion 5 and a .partial perspective thickening in form of an intermediate portion 6 of the member 1.
  • a recess or depression 8 is provided in the exposed end face of the head portion 5 and permits the introduction of a suitable means for effecting turning of the member 1 about its longitudinal axis, for instance the insertion of a coupling head of polygonal cross section provided on another structural element of a toy assembly kit in conjunction with which the invention is to be used.
  • the recess 8 can of course also be in form of a slot for use with a screw driver.
  • the thickened intermediate portion 6 extends from the head portion 5 slightly beyond the surface of the element 2 which is juxtaposed with the element 3.
  • the portion 7, that is the free end portion of the member 1 extends into the aperture 11 of the element 3.
  • the arresting portion 9 of the member 1 is provided with two diametrally opposite projections 10. As is clear the portion 9 extends beyond that surface of the element 3 which faces away from the element 2 so that the projections 10 overlie such surface.
  • Recesses l2 (compare FIG. 2) are provided through which the projections 10 pass as the member 1 is first inserted through aperture 4 and then the aperture 11. Thereupon the member 1 is turned about its longitudinal axis and the projections 10 engage the element 3 in looking relationship.
  • an abutment or stop 13 is provided. This is shown in FIG. 2.
  • the portion 9 is provided with a conically tapered tip 14 for facilitating insertion into the apertures 4 and 1 1.
  • the portion 9 is provided with two diametrally opposite undercuts or depressions which correspond in shape to the undercut groove 16 of a structural ele ment 17 which also forms a part of a toy building kit in which the present invention is to be utilized.
  • the projections 10 extend at right angles to the direction of the undercuts l5 and provide for visual alignment in that they simply are aligned with the longitudinal axis of the groove 16 whereby a proper location of the recesses 15 with respect to the undercut groove 16 is achieved.
  • the undercut groove 16- would receive correspondingly configurated undercut male coupling heads provided on others of the building blocks 17, but here the member 1 is used to connect to this building block 17 in the illustrated manner the element 2.
  • the narrow top portion of the groove 16 constitutes an aperture which extends between the top surface of the element 17 and the concave surface surrounding the main portion of the groove 16.
  • the undercuts 15 in the arresting portion 9 of the member 1 shown in FIGS. 3 and 4 provide two projections which are angularly offset with reference to the projections 10 and engage the concave surface surrounding the groove 16 when the member 1 is mounted in a manner as shown in FIG. 3.
  • the head portion 5 is provided with a substantially wingshaped gripping or engaging portion 18 which greatly facilitates ready turning of the member 1 about is longitudinal axis. If the portion 18 is in the way at the outer side of the member 2, then the member 1 is inserted from the inner side through the openings 4 and 11 and the arresting is accomplished again by turning. In this case the portion 9 is accommodated in a depression 19 and does not project beyond the outer side.
  • the element 3 is of L-shaped cross section, as is the element 22 which here has an arm 21 and an upright arm 24 projecting upwardly beyond that surface 20 of the arm 21 which faces away from the element 3 and from which the aperture 4 extends inwardly.
  • the head portion of the member 1 is again identified with reference numeral 5 but here has such a height or length that its free end face is at least located in the plane of the surface 23 on the arm 24 so that the latter will not interfere with turning of the head portion 5.
  • the portion 9 of the member 1 projects beyond the surface 25 of the element 22 through the aperture 11 of the element 3 for effecting locking in the aforementioned manner.
  • Reference numeral 29 identifies a bore extending inwardly from the recess 8 into the head portion 5 and capable of accommodating a shaft. 30 (see FIG. 7).
  • FIG. 7 shows that the member 1 is connected with the building block 27, or rather with the undercut groove 16 thereof, by means of the undercuts or recesses 15 as illustrated.
  • Reference numeral 28 here identifies a projecting male coupling head of undercut configuration such as to mate with grooves analogous to the groove 16 but in other structural elements which are not illustrated.
  • the Configuration of the coupling head 28 corresponds to that of the recess 8 (see FIG. 6) in the free end face of the head portion 5 so that if a coupling head 28 of any structural element provided therewith is inserted into the recess 8, it can serve for effecting turning of the member 1 about its longitudinal axis between a connected and a disconnected position.
  • a shaft 30 will be seen to be releasably accommodated in the bore 29.
  • a connecting arrangement for use in a toy assembly kit comprising a first element having first and second surfaces and a first aperture extending between said surfaces; a pair of additional elements separably connectable interchangeably with said first element and having first surfaces adapted to be placed adjacent to the first surface of said first element, second surfaces, and apertures extending between the respective first and second surfaces of said additional elements and movable interchangeably into register with said first aperture, the configuration of said second surface of one of said additional elements being different from the configuration of the corresponding surface on the other additional element; and a connecting member for separably connecting said first element with a selected one of said additional elements, said connecting member having a first end portion movable into abutment with the second surface of said first element, a median portion insertable into said first aperture, and a second end portion having at least one first projection extending transversely of the longitudinal axis of said connecting member, said first projection having a first engaging surface arranged to engage the second surface of one of said additional elements when the first surface of said one additional element is adjacent to the
