Definitions

  • the invention relates to a mobile multi-purpose children's toy according to the preamble of claim 1, which is drivable and steerable from a driver's seat and can also raise and lower loads.
  • a multi-purpose mobile children's toy is known, on the chassis of which there is a lifting mechanism on which a gripper bucket, as is usually used in excavators, hangs.
  • the gripper shovel is actuated via a divided cable drum, on each of which a lifting and a gripper shovel operating cable can be wound up or unwound.
  • the gripper blade By turning a crank which is rigidly connected to the cable drum, the gripper blade can be actuated, i.e. opened and closed and raised and lowered.
  • the two cable drum halves are connected by means of a single-claw coupling, so that it is possible that the operating cable of the gripper shovel is wound up or unwound and the shovel jaws close before opening or before lowering.
  • the effort required to lift, lower or actuate the gripper shovel is determined by the lever arm, which is determined by the distance of the crank from the cable drum shaft, and halved again by using a loose roller on the gripper shovel (DE G 91 01 046.2).
  • the respective rope length of the two ropes is doubled, and a correspondingly large space requirement for the rope drum is required when the entire rope length is wound on the rope drum halves.
  • only a limited power transmission ratio can be realized in this form.
  • the invention begins, which is based on the object of further developing a mobile multi-purpose children's toy with a lifting mechanism on which a gripper shovel hangs, so that a compact design enables lifting, lowering or actuation of the gripper shovel with a force that is favorable for children becomes.
  • crank wheel As an essential component of a planetary gear train, a favorable transmission ratio for actuating the gripper blade can be achieved with very little space requirement.
  • the gear diameter and number of teeth can be adjusted very easily.
  • a loose roller on the gripper blade can be dispensed with, since the required actuating force of the gripper blade can already be sufficiently reduced by the planetary gear mechanism and thus only half the rope length has to be wound or unwound on the rope drum. Of course, this reduces the required cable drum diameter for coiled cables.
  • the opposite case is also possible, in which the web is locked and disengaged and the rotational movement is transmitted from the crank to the sun, planet and ring gear and from there via the clutch to the cable drum.
  • This allows two gear ratios to be implemented in a simple manner with a small space requirement.
  • the two different gear ratios can be used accordingly can be used to use the larger ratio for lifting or lowering the grab bucket and the smaller only for actuating the grab bucket.
  • the web of the epicyclic gear mechanism should run sleeve-like on the common shaft within the cable drum diameter and be connected to the cable drum half facing away from the crank.
  • the ring gear can be connected to the other half of the cable drum outside the inner diameter of the cable drum.
  • the clutches can be dispensed with if the web is rigidly connected to one cable drum half and the ring gear is rigidly connected to the other cable drum half and a locking device is provided on both cable drum halves.
  • a locking device is provided on both cable drum halves.
  • either the cable drum half for actuating the gripper shovel or the cable drum half for lifting or lowering the gripper shovel can be driven.
  • the locking device can be designed so that it either locks one cable drum or the other cable drum, so that only one actuating element is required.
  • a gripper shovel 9 from the driver's seat via a crank 6 by driving a cable drum which is divided into two and with which the lifting and lowering is driven via the crank 6 or the opening and closing of the gripper shovel 9 can be carried out from the driver's seat.
  • a non-rotating gearbox with only one gear ratio is used (Fig. 2).
  • the epicyclic gearbox is enclosed in a housing shape by the crankcase 6.
  • the hub-shaped sun gear 1 which is rigidly connected to the crank 6, drives the rotatably mounted web 2, which is rigidly connected to at least one cable drum half 4 or 4a, via a planetary gear set 8.
  • the ring gear 3 is firmly connected to the vehicle chassis via a fixed locking element 7 and therefore cannot rotate.
  • the translation of the rotary movement takes place via sun gear 1, planet gears 8 and web 2 on the cable drum halves.
  • the hub-shaped sun gear part 1 of the crank 6, a part of the web 2 and the two cable drum halves 4, 4a are rotatably mounted on a common shaft 5 and secured against axial displacement.
  • the children can see how it works of such a gear transmission visually detect and recognize the corresponding functional principle.
  • the functioning of the two-part cable drum can be seen from the illustration according to FIG.
  • the cable drums 20, 21 are driven by the crank 6 and the epicyclic gear connected to it.
  • the crank 6 When the crank 6 is rotated, the cable drum half 20 is first rotated and the gripper blade actuating cable 28 is wound up or unwound before the claw coupling 23, 24 located between the two cable drum halves moves the second cable drum half and the lifting or lowering of the gripper blade takes place after about an almost complete rotation .
  • Ratchets 25, 26 are available for self-locking against unintentional actuation. These ratchets 25, 26 can be used with a suitable design for locking the web 2 or the ring gear 3 in a two-stage design of the epicyclic gear, and thereby both functions can be combined.
