  • the head comprises a neck portion which is rigid with the axial end face in question and securing means which includes a securing portion of a cross-section greater than the neck portion.
  • the present invention relates to an assembly kit and, more particularly, to a structural element used in an assembly kit of the type comprising building blocks provided with at least one undercut elongated groove.
  • Building blocks are known from my prior applications which are provided in one or more faces thereof with elongated undercut grooves, that is with grooves which diverge inwardly from the respective face in which they are formed.
  • Such blocks are connected to one another and to auxiliary building elements by means of connecting heads, frequently integral with the blocks or the auxiliary building elements, which are configurated in a manner complementary to the cross-section of the grooves, i.e. which have a relatively narrow neck portion connected to a building block or an auxiliary building element and a wider head portion which is received in one of the grooves of another block with the narrow neck portion extending outwardly beyond the groove.
  • kits utilizing such building blocks can be employed in the construction of many and diverse projects, such as buildings, trucks, and the like the versatility of such kits can be further increased if they are provided with one or more pulleys for ropes which are to be used for motion-trans mitting purposes.
  • a more specific object of the invention is to provide a pulley member which can be utilized in assembly kits of the above-mentioned type.
  • a further object of the invention is to provide such a pulley member which can be rigidly but releasably secured to other building blocks or elements in the assembly kit.
  • Aconcomitant object of the invention is to provide a pulley member of the type described which can be reliably secured to a shaft, or which can have a shaft reliably secured thereto, without axial shifting of one relative to the other or rotational displacement of one relative to the other.
  • one feature of my invention resides in the provision of a pulley member in an assembly kit of the type which comprises building blocks provided with at least one undercut elongated groove.
  • Such pulley member comprises a tubular center portion and radially extending flange portions at opposite ends of the tubular center portion.
  • the radially extending flange portions are provided with oppositely directed axial end faces.
  • At least one of the axial end faces is provided with a connecting head which extends in axial direction beyond this end face and is adapted to be at least partly received in an undercut groove of a building block to which the pulley member is to be secured.

  • FIG. 8 shows a pulley in accordance with the present invention in another embodiment and connected to a building block
  • FIG. 9 is a view showing the embodiment of FIG. 5 connected to a building block and disconnected therefrom;
  • FIG. 10 is a top view of the illustration shown in FIG. 9;
  • FIG. 11 is a partially sectioned view of another embodiment of the invention, showing a compressing means in cooperation with a pulley member as shown in the preceding drawings;
  • FIG. 12 is a view similar to that of FIG. 11 but rotated through 90;
  • FIG. 13 is an axial view through the compressing means shown in FIG. 11;
  • FIG. 14 is a view of the embodiment of FIG. 13 as seen in the direction of the arrow A.
  • FIG. 1 there is shown therein and having at the opposite ends thereof respective a pulley member 1 having a tubular central portion flanges 2 and 3.
  • One of the flanges namely in the illustration flange 3 is provided with a slot 4 which extends over the entire length of the tubular central portion also.
  • Each of the flanges 2, 3 is provided with two diametrically opposite connecting heads 5, 6 and 7, 8 having a configuration as shown in FIG. 2, that is being undercut in the sense that a wider portion located spaced from the respective flange is connected to the same by a narrower neck portion.
  • These connecting heads can be utilized to secure the pulley member 1, which is shown in FIG.
  • FIG. 4 shows by way of an example how a building block 9 is secured to one of the heads, namely the head 7 of the pulley member and it will be seen that the head 7 is engaged in the undercut groove 9a of the building block 9.
  • an additional building block can be connected to the building block 9 by way of similar connecting heads provided on the respective building blocks. This is indicated only for information as it does not form a part of the present invention.
  • a shaft 10 is inserted through the center opening of the pulley member 1 and this is simplified by the provision of the slot 4 which permits resilient deflection of the material of pulley member 1. As shown, slot 4 simultaneously serves for fastening the end of the rope or belt 11 which is connected to the pulley member 1.
  • FIG. 5 shows a modification of the inventive concept.
  • the pulley member shown in FIG. 5 is designated with reference numeral 101 and is provided again with the connecting heads 102, this designation having been utilized to designate all of the connecting heads in this embodiment.
  • Each of the connecting heads in this embodiment is provided with a projection 103 which extends in axial direction of the pulley member 101.
  • the projections 103 have a crosssection which does not exceed the cross-section of the neck portion of the connecting head 102 so that the connecting portions 103 can 'be received in the narrower part of the grooves 105 (see FIG. 8) of building blocks to which the pulley member 101 is to be secured, in the same manner in which the neck portion of the connecting head 102 is normally received in these grooves 105.
  • these portions 103 can be inserted into the grooves 105 transversely of the elongation thereof to hold the pulley member 101 to any other auxiliary element or building block provided with such grooves.
  • the connecting head 102 then abuts the face of the respective building block to which it is to be secured with the shoulders 110 formed at the base of the projection 103.
  • FIGS. 6 and 7 show different views of the embodiment of FIG. 5 for purposes of explanation.
  • FIG. 8 differs from that of FIG. 5 in that the projection 103 is undercut in a T-shape as indicated with reference numeral 111. This serves to provide a better retention of the projection 103 in the respective groove 105 against forces acting in axial direction of the pulley member 101 and tending to remove projection 103 from the groove 105. Of course, this arrangement will not be able to withstand forces of such magnitude as the embodiment of FIGS. l4.
  • FIGS. 4 and 5 illustrate, by way of example, how the embodiment of FIGS. 5-7 can be utilized in constructing certain building elements.
  • the shaft on which the pulley member 101 is mounted is designated with reference numeral 104 whereas the building blocks 107 are shown to be provided with undercut grooves 105.
  • a rotary handle connected to the shaft 104 on a side of the building blocks 107 opposite that on which the pulley member 101 is located, is designated with reference numeral 109 and provided with a peripheral annular groove 108.
  • the pulley member 101 is disengaged from one of the grooves 105, as shown in the full-line position of FIG. 9, that is if it is moved towards the right as indicated by the double-headed arrow a,
  • FIG. 10 shows a top view of the embodiment of FIG. 9 for greater clarity.
  • Reference numerals 2 and 3 again indicate the respective flanges provided on the pulley member
  • reference numeral 4 indicates the axial slot
  • reference numerals 5 and 6 indicate the connecting heads carried by one of the flanges, namely the flange indicated with reference numeral 2.
  • a compressing member 21 is provided of generally annular configuration having a through-going center bore and a larger-diameter portion concentric with the center bore. As shown in FIG.
  • the peripheral wall surrounding the larger-diameter bore tapers inwardly in the direction away from the open end of the member 21; that is, the cross-section of the larger-diameter bore converges in the direction towards the smaller-diameter bore 23 through which the shaft 10 passes.
  • the compressive action can be increased further if the smaller-diameter opening 23 for passage of the shaft 10 is located slightly eccentrically.
  • the member 21 may be provided with a collar 22a at the open end of the largerdiameter bore and this increases frictional engagement with the respective flange and when the member 21 has been placed over such flange and completely encloses the same, snaps into position to prevent undesired removal of the member 21.
  • the outer peripheral face of the member 21 can be knurled, as indicated with reference numeral 24, to provide a better grip.
  • a pulley member comprising a tubular center portion; radially extending flange portions at opposite ends of said tubular center portion and provided with oppositely directed axial end faces; and a one connecting head provided on at least one of said axial end faces and extending in axial direction therebeyond, said connecting head being at least partly received in an undercut groove of a building block to which said pulley member is to be secured and comprising a neck portion rigid with said one axial end face and securing means including a securing portion of a cross-section greater than said neck portion.
  • said securing means further comprising a projection extending from said securing portion in axial direction of said pulley member and away from said axial end face thereof.
