Definitions
- the invention is directed to a toy vehicle with one around Swivel-mounted boom, such as Crane boom, the can be swiveled up via a crank drive.
- a toy vehicle can be used especially as a fire engine or crane vehicle be trained, such toy vehicles have always been one particularly popular with children because the extension of a Cantilever or a ladder offers a high play appeal.
- the object of the invention is such To design a toy vehicle so that the gearbox can be swiveled up the boom is easy and effective to operate on the one hand and on the other hand, be accommodated in the smallest possible space can.
- the boom is approximately U-shaped in cross section that on the inside of the U-legs formed opposite cam guide curves are in the two opposite cam lugs of the threaded nut intervention.
- the threaded nut in Longitudinal direction of the threaded spindle to be divided and expandable elastically, so that this allows the thread engagement to be overcome.
- the boom can be extended telescopically an approach is arranged, one driven by a crank Gear engages in a rack of the boom.
- the approach can be as Be formed ladder or for example as a loading shovel.
- the invention provides that the teeth of the gear and the rack are rounded and the distance between the teeth is chosen so that when a force is applied of the boom on the inside of one tooth of the rack a corresponding tooth of the gear a force in the direction of Center of the gear exerted and thus realized a tension becomes.
- a locking mechanism ensures end position stability reached in the extended state.
- An excavator trailer shown in the drawing comprises a chassis 1 with a front and rear pair of wheels 2, 3. On a rear, extending upward extension 4 of the chassis 1 is a boom 5 around a pivot axis 6 pivotally mounted.
- the boom 5 is U-shaped in cross-section, with approaches 7 of the U-side walls cam guide curves 8 by projecting inwards Bridges are formed, which in the drawing towards the bottom right are open.
- a threaded spindle 11 On the chassis 1 is on transverse walls 9, 10 in the same recesses a threaded spindle 11 rotatably supported by a crank 12. On the threaded spindle 11 sits a threaded nut 13, which face each other lying sides cam lugs 14, each in the cam guides 8 intervene.
- the threaded nut 13 can be slotted in the direction of the longitudinal axis 15. Accordingly, when a child presses the boom 5 while playing and thereby exerting a relatively large leverage, the threaded nut can 13 elastically expand and along the thread of the threaded spindle 11 slide along so that damage to parts is avoided.
- an extension 16 which in the exemplary embodiment is an excavator shovel 17 carries, telescopically mounted longitudinally.
- a rack 18 is formed, the from a plurality of recesses and between the recesses 20 trained teeth 21 there.
- a gear 19 is on the boom 5 rotatably supported by a crank, not shown in the drawing, which with its teeth 21 in the recesses 20 of the rack 18th engages so that by turning the gear 19, the approach 16 relatively to the boom 5 is retractable and extendable.
- the distances between the teeth 21 of the rack 18 on the one hand and the teeth 22 the gear 19 on the other hand are selected and the teeth 21, 22 such rounded that when exerting a force in the longitudinal direction over two to each other pushing teeth 21, 22 a force towards the center of rotation of the gear 19 is exerted and thereby blocks the movement will, i.e. there is the effect of a locking gear.
