Definitions

  • the invention concerns a toy coupling mechanism incombination with a toy building set with a rod-shaped object and a coupling head, said coupling mechanism being adapted to be used in a toy building set containing various building elements with other types of coupling means, e.g. bushings and ball heads.
  • constructions of this type are not suitable for use in toy building sets, since consideration has been paid to the forces occurring in practice when constructing the cables and when arranging the means used for fixing the cables to the construction in general, while mounting is often difficult and requires the experience of a skilled person.
  • Swedish patent No. 351 369 describes a flexible building element for a toy building set.
  • the building element has a coil spring terminated at each end by a coupling head which can be coupled with the other elements of the toy building set.
  • the coil spring and the coupling heads form an integral part and it is thus not possible to change the coupling heads.
  • the object of the invention is therefore to provide a toy coupling mechanism which is to be used in an existing toy building set for transferring forces between various elements in constructions built with the toy building set, e.g. for transferring pressure, pull and rotation between the individual construction elements or e.g. for stabilizing a static construction built with the toy building set, where such a coupling mechanism must of course be easy to mount and be connectible with various building elements in the toy building set.
  • This object is achieved with a by coupling mechanism in combination with a toy building set as defined in claim 1.
  • This provides a releasable connection between the rod-shaped object and the coupling head, e.g. in the form of a snap action, whereby these two parts can easily be engaged with and disengaged from each other.
  • the secondary coupling means of the coupling head may e.g. comprise a cylindrical eye adapted to receive a cylindrical bushing, or having two axially spaced stop means inside the eye so that a ball head can be received rotatably.
  • the rod-shaped object has a circular cross-section and a constriction spaced from the end to receive the terminal part. Upon interconnection of two parts of the coupling mechanism, this collar will counteract axial movement of the rod-shaped object with respect to the coupling head.
  • the two resilient walls are normally connected by a portion of material extending in the axial direction of the rod-shaped object. When coupled with the coupling head, the rod-shaped object can then be caused to engage said portion of material.
  • the rod-shaped object may be adapted to be passed through a tubular liner or envelope with an internal diameter corresponding to the diameter of the object. This is feasible when the rod-shaped object is formed with a terminal part whose diameter is smaller than or equal to the diameter of the rest of the rod-shaped object.
  • the rod-shaped object may be used as a type of Bowden cable where the travel of the cable with respect to the end point of the liner may be used for displacing parts in a construction built with the toy building set.
  • the cable liner may advantageously be attached in a bushing whose outer diameter corresponds to other parts incorporated in the toy building set, so that the cable lining may be fixed in existing building elements.
  • the rod-shaped object preferably has a terminal part at each end so that a coupling head may be mounted at each end.
  • one end of the rod-shaped object is an integral part of a component incorporated in the toy building set. It may thus be connected directly to the piston rod in a pressure operated cylinder.
  • the rod-shaped object may also be formed with a terminal part having e.g. a four-sided cross-section, so that the coupling mechanism will be able to transfer torsion or rotation between two construction parts.
  • Fig. 1 shows a preferred embodiment of a rod-shaped object 10 for a coupling mechanism according to the invention.
  • the rod-shaped object 10 has a terminal part consisting of a constriction 15 which forms an integral part of the rod-shaped object 10.
  • the constriction 15 is connected to the end 12 and main body of the rod-shaped object 10, respectively, by two frusto-conical parts 13, 14.
  • the rod-shaped object 10 has a maximum diameter corresponding to the diameter of the main body.
  • Fig. 2 shows a coupling head 20 for the coupling mechanism, where the coupling head 20 has two resilient walls 27 adapted to releasably receive and retain the terminal part of the rod-shaped object 10.
  • the coupling head 20 is a flat, oval body with a cylindrical, through-going eye 21 at one end, which is adapted to rotatably receive and retain a cylindrical bushing on another building element incorporated in the toy building set.
  • a circular channel 23 is provided between the two resilient walls 27 in the longitudinal direction of the coupling head 20, said channel serving to receive the terminal part of the rod-shaped object 10.
  • a cavity is formed between the resilient walls 27 on the coupling head 20 and is divided into an inner part 24 and an outer part 22, between which a collar 28 is provided, extending between the cavities 22, 24 transversely to the longitudinal direction of the coupling head 20.
  • the coupling head 20 is typically manufactured by injection moulding of a plastics material, so the coupling head 20 may in certain areas be formed with recesses 25 to reduce the wall thickness and to thereby achieve the best possible product.
  • Fig. 3 shows a coupling head 30 substantially corresponding to the one shown in fig. 2, where a cylindrical eye is adapted to rotatably receive a ball head; the eye therefore has two axially spaced stop means 36 which may e.g. consist of two spaced rings or, as is the case here, parts of two such rings.
  • Two resilient walls 37 form an outer and an inner cavity 32, 34 separated by a collar 38.
  • a rod-shaped object 10, displaced laterally, may be received in a substantially circular channel 23 which forms the rear wall of the cavities 32, 34 formed by the resilient flaps 37.
  • some recesses 35 of reduced thickness may be provided owing to the wall thickness.
  • Figs. 4 and 5 are a lateral view and an end view, respectively, of the coupling head 30 shown in fig. 3. It is seen in fig. 4 how the inner part 34 of the cavity formed by the resilient walls 37 has the shape of the end 12 on the rod-shaped object 10. The width of the cavity 34, i.e. the distance between the two resilient walls 37 in this part, is constant in the entire depth of the cavity. Thus, the end 12 on the rod-shaped object 10 will not meet with any resistance until it reaches the rear wall of the inner part 34 of the cavity. It is seen in fig. 5 how the outer part 32 of the cavity is hopper-shaped so that the resilient walls 37 of the coupling head 30 are forced apart in this area upon mounting of the rod-shaped object 10.
  • the rod-shaped object 10 can only be disengaged when subjected to strong lateral forces.
  • the collar 38 which separates the inner and outer parts 34, 32 of the cavity, is formed with inclined walls which correspond to the frusto-conical part 13 of the rod-shaped object, so that the collar 38 on the resilient walls 37 will yield when the pull in the rod-shaped object 10 in an axial direction exceeds a certain value, and the rod-shaped object 10 will therefore not be destroyed in case of overloading.
  • the coupling head 20 for receiving a bushing is oval, while the coupling head 30 for retaining a ball head is U-shaped. A user can hereby readily distinguish between the two types of coupling heads 20, 30.
  • Fig. 6 shows an application of a coupling mechanism according to the invention, where a coupling head 30 is mounted at one end of a flexible cable 10.
  • the other end of the cable 10 is secured to a piston 61 in a pressure-pull cylinder 60, said cable 10 being passed through an opening in the end plate 62 of the cylinder 60.
  • the cylinder 60 is operated by a pump 63.
  • Two uniform elements 40 and 42, together with the pressure operated cylinder 60, are fixed to a construction built with the toy building set. These two building elements 40, 42 have a circular opening to receive a bushing 41 and 43, respectively.
  • These two bushings 41, 43 retain their respective ends of a tubular envelope 50 with respect to the two building elements 40, 42.
  • the envelope 50 will preferably be flexible and formed with- an inside diameter corresponding to the diameter of the rod-shaped object or the cable 10. Since the cable 10 can easily be separated from the coupling head 30, this can easily be passed through with a tubular envelope 50.
  • the cable 10 is passed through the envelope 50 after the envelope has been attached to the building elements 40, 42 by means of the bushings 41, 43.
  • the travel of the piston 61 in the pressure operated cylinder will thus be transferred through the cable 10 so that the coupling head will perform a corresponding travel with respect to the building element 40. This travel may be used for moving other parts (not shown) of the construction.
  • Fig. 7 shows an example of an application of such a cable construction.
  • the shown construction may e.g. be used for regulating the inclination of a toy helicopter rotor.
  • a power supply and regulation device 104 controls the supply power to an electric motor 100.
  • the electric motor 100 has a drive shaft, which through a connector 105 is connected to the rotor shaft of the helicopter.
  • the shaft is moved through a flat building element 120 with holes to receive shafts and bushings.
  • the shaft 120 is retained vertically with respect to the flat building element 120 by means of positioning rings 122 mounted on each side of the flat building element.
  • the shaft 110 is secured to a cardan ball (not shown), which is engaged with carrier pins on an internal cylinder face on a cross-shaped element 130, so that its rotation is provided by the shaft 110.
  • the cross-shaped element 130 has four radially protruding arms with coupling studs 132 with which helicopter blades may be mounted.
  • a guide ring 140 is rotatably journalled about the tubular part of the cross-shaped element 130, so that the guide ring 140 may be used for regulating the inclination of the element 130 with respect to horizontal.
  • the guide ring 140 has four radially protruding arms with ball heads 145.
  • a coupling head 160 of the second type (30) is secured to one of these ball heads 145.
  • this coupling head 160 is connected with a flexible cable 160 and is passed into a bushing 180 extending through the flat building element 121 as well as an additional element 122 whereby the bushing will be able to retain a flexible envelope 170, whose other end is secured with a bushing 181 to a building element 185.
  • the cable 160 is attached at its other end to a coupling head 155 of the first type (20), which is secured via a bushing 190 to a lever or swing arm 192 which may be pivoted about a stationary pivot shaft 195.
  • the shaft 195, the building element 185, the building elements 120 and 121 and the electric motor 100 are secured to stationary construction parts which are omitted for the sake of clarity.
  • the cable 160 When the swing arm 192 is pivoted about the shaft 195, the cable 160 will be displaced in the envelope 170, and the rotation about the shaft 195 will result in a linear displacement of the coupling head 160 and thereby change the inclination of the cross-shaped element 130.
  • the ball heads 145 of the guide ring 140 When connecting one more of the ball heads 145 of the guide ring 140 with a guide device, it is possible to regulate the inclination of the plane spanned by the cross-shaped element, Altematively, one of the ball heads may be fixed with respect to the flat building element 120, so that the element 130 can now only tilt about an axis.
  • Fig. 8 shows that the coupling mechanism according to the invention may be used for stiffening stationary constructions, which is exemplified by a tail portion of a helicopter built with the elements of the toy building set.
  • the tail portion is composed of long building elements having through openings to receive shafts.
  • the construction consists of five beams 210, 220, 230, 240, 250 which are coupled together with shafts and bushings to form a substantially trapeziform body constituting the tail of the helicopter. Since the individual beams are rotatably connected with each other, the tail portion will not be stable as such, and two stiffening elements 260, 270 are therefore connected between the two substantially parallel beams 210 and 240.
  • These stiffening elements 260, 270 consist of a cable 10 provided at each end with a coupling head 20, which is secured to respective beams 210, 240 by means of bushings or shafts extending through the openings of the beam.
  • Fig. 9 schematically shows how a cable construction of the type shown in fig. 6 may be used for controlling the shape of an otherwise semistatic construction.
  • the construction is formed by four beams 300, 301, 302 and 303 which are rotatably secured to each other through shafts 380, 381, 382 and 383.
  • the beams 301-303 form a trapezium whose shape may be varied by adjusting the angle between two of the beams 300 and 303 forming part of the parallelogram.
  • a Bowden cable comprises a envelope 360 attached to the beam 300 and an inner cable 310 attached to the beam 303 through a coupling head 320 by means of a bushing. The travel of the inner cable 310 in the envelope 360 will thus be able to adjust the angle between the beam 300 and the beam 303.
  • Fig. 10 shows an alternative embodiment of the rod-shaped object where the terminal part is here formed with an end part 12a having a square cross-shaped section.
  • the rod-shaped object 10 otherwise corresponds to the rod-shaped object shown in fig. 1, but owing to the plane faces 12a of the end part. it will be able to transmit rotary movements or torsion if the coupling head is formed with corresponding complementary plane faces.
