Definitions
- the invention is directed to a toy gantry crane, comprising one horizontal cross member with a running rail for a movable winch and beams arranged at the ends of the cross beam.
- portal cranes have a high appeal because they allow to maneuver a vehicle specifically under the horizontal crossmember and to lift loads from the vehicle bed by means of the winch.
- the object of the invention is a toy gantry crane to create a high functionality and on the other hand, a simple construction that is easy to implement in terms of plastics technology has space-saving storage due to easy disassembly allows.
- the running rail and cross members consist of tubes that are connected to one another via connecting elements are releasably connected.
- the connecting elements preferably Have plug sleeves for the two crossmember tubes.
- transversely extending retaining webs are formed between the receiving cheeks, correspondingly in the area of the inside of the receiving cheeks the wall thickness of the pipes spring back, i.e. slot-like recesses train in which the pipes to be fixed engage in such a way that the support bar extends across the center of the tube opening.
- the front of the retaining webs is slightly concave.
- each carrier is advantageously formed by two V-shaped support tubes, wherein each carrier tube can be inserted into a socket of a connecting element is. This also enables easy disassembly, when the support tubes are in the storage condition described above should be brought.
- the support tubes and the cross support tubes are preferably of the same length, so that they form a parallel tube bundle when stored can.
- foot elements attachable, which compensate for the oblique inclination of the support elements and enable a flat and stable support on the floor.
- the invention is also directed to a cable winch, in particular for a Toy gantry crane of the type described above, which is characterized by distinguishes that they have pivoted front and rear pairs of Has rollers which are provided with a concave tread, whose radius of curvature corresponds approximately to that of the cross member tubes.
- a cable winch it can be provided that it has a hand crank that drives a worm with a gear combs, which is in drive connection with a winch drum, the snail between the actual snail body and a end bearing a resilient portion of tapered diameter having. In this way, if the output is blocked, that the snail can bend and so out Engagement with the gear comes in so that damage is avoided become.
- a toy gantry crane 1 shown in the drawing comprises six Pipes that are detachably connected via connecting elements 2 can.
- the cross member tubes 3 are positively in receptacles 5 of the connecting elements 2 inserted.
- a vertical socket 6 in each of which a Carrier tube 7 can be inserted.
- the vertical sleeves 6 are V-shaped to each other, so that the inserted carrier tubes Extend in a V-shape at both ends of the crossmember tubes.
- the lower ends 8 of the support tubes are in a foot part 9 via a Plug sleeve 10 inserted, which ensures a secure stand of the entire arrangement guaranteed.
- the connecting elements 2 face the vertical plug-in sleeves 6 extending cheeks 11, between which there are holding bars 12 extend.
- the holding webs 12 have a concavely curved inwards Face 13 with side undercuts 14 approximately according to the Wall thickness of the support tubes 7, with the retaining cheeks 11 from each other have a distance that is about the outer diameter of the carrier tubes 7 corresponds.
- the movable cable winch 4 has a housing 15 on the underside thereof two pairs of rollers are arranged, each roller 16 a concave Has tread 17 whose radius of curvature is approximately the radius of curvature the carrier pipes 3 corresponds.
- a Guide element 18 snap-on On the underside of the housing 15 of the movable cable winch 4 is a Guide element 18 snap-on, which has a shaft 19 for the rope 20th the winch and the crane hook 21 attached to the end of the rope is.
- a cross member 22 has roller-shaped rollers 23 which are concave Tread 24 with a radius of curvature approximately corresponding to that Have radius of curvature of the cross member tubes 3.
- the rope 20 can be wound on a rope drum 25, which with a Gear 26 is in drive connection.
- the gear 26 is in turn with a perpendicular to the central longitudinal axis of the gear 26 Screw 27, which, like the drum 25, is mounted on the housing 15 is and is driven by a crank handle 28.
- a tapered section 30 in the extension of the screw 27 provided an elastic yielding of the screw 27 downwards made possible if an output blocking occurs. This can disengaged the teeth of gear 26 from the worm and damage is avoided.
