Definitions

  • the invention relates to a toy spinning top with the features specified in the preamble of claim 1.
  • Toy spinning tops generally have a base in which a vertical, fixed base axis is held with its lower end.
  • the connection between the pedestal and the pedestal is to be designed to be deductible, on the one hand to prevent the gyroscope from being actuated on the relatively sharp-edged end of its pedestal and thus causing damage to floors or furniture.
  • the exposed end of the standing axis would pose a considerable risk of injury to the children handling such a damaged spinning top.
  • the actual gyroscope body is rotatably mounted on the fixed standing axis.
  • this mounting must ensure that the gyro rotation axis is held in a sufficiently precise vertical position and that the gyro body is effectively supported against its weight and the driving force acting downwards through the action of the swirl rod.
  • two radial and one axial plain bearing are available between the standing axis and the gyro body.
  • a first radial slide bearing is formed by a central, bush-like bearing opening in the tip part of the rotary body, which is preferably made of an injection-moldable or pourable plastic.
  • the standing axis extends vertically upwards through this bearing opening.
  • the second radial plain bearing is centered by another cal, bush-like bearing opening in an attached in the tip part, also preferably made of an injection or castable plastic insert.
  • the upper end of the standing axis lies in this bearing opening.
  • the vertical spacing of the two radial plain bearings ensures that the gyro rotation axis is kept vertical. Since relatively small transverse forces occur between the standing axis and the tip or insert part and the standing axis is held in the bearing openings with corresponding play, the sliding friction forces in these bearings are negligibly small.
  • the lower ring disc can stand still due to the crushing, while the upper one can rotate with the insert part and consequently the tip part.
  • the plain bearing therefore takes place between the two metal ring disks and accordingly has a low sliding friction resistance got up and wear.
  • the said crimping also serves as a trigger protection for the gyro body from the standing axis.
  • a disadvantage of this known construction is its extremely high installation effort.
  • the two washers must be threaded onto the standing axis.
  • assembly of the gyroscope on production machines is difficult because of the difficult handling of the washers.
  • the object of the invention is to simplify and improve the bearing construction of the gyro body on the standing axis with regard to the manufacturing effort and, in particular, to enable automatic production.
  • the axial bearing which has been regularly pursued in the prior art, is completely abandoned by crushing on the standing axis and bearing ring washers sitting thereon and is replaced by a design of the metal bearing elements in the manner of, for example, a tip bearing.
  • One bearing element is itself formed by the upper end face of the standing axis.
  • the other bearing element is realized by a bearing ball arranged on this end face, which sits at the closed inner end of the blind hole-like bearing opening of the insert part which is slipped over the upper end of the standing axis.
  • the subject matter of the invention designed in this way can also be easily assembled by a production machine, since only the ball is inserted into the blind hole-like bearing opening of the prefabricated insert, then the stand axis is inserted and the arrangement thus created is inserted into the tip part. In a final step, the stand can be pushed onto the lower end of the stand axis.
  • Another advantage lies in the reduced sliding friction between the bearing ball and the standing axis compared to the prior art, since there is an essentially point-like metal-metal contact.
  • the insert part with the bearing ball already inserted can be provided as a pre-assembled part for final assembly of the gyro.
  • the mounting of the bearing ball can be done by gluing, melting or - as indicated in the characterizing part of claim 3, it is self-locking with a press fit.
  • the bearing ball can, for example, be introduced into the bearing opening simultaneously with the injection molding or pouring of the insert part.
  • the gyroscope has a base (1) designed as a flat-conical plastic molded part, in the tip of which an insertion opening (2) for the lower end (3) of the base axis (4) is formed.
  • this insertion opening (2) the coaxial to the axis of rotation (5) of the actual (indicated by dashed lines) gyro body (6) standing axis (4) by means of the hat-like spring washer (7) is held trigger-proof and rotation-proof.
  • the foot construction shown is the subject of European Patent No. 197092 (EP patent application 85 904 058.7).
  • the gyroscope body (6) is rotatably mounted on the standing axis (4).
  • it has at its lower end the multi-part bearing structure (8) which is essentially formed by the approximately frustoconical tip part (9) facing the base (1) and the insert part (11) sitting in its hollow interior (10).
  • the standing axis (4) passes through the tip part (9) made of a sprayable plastic vertically upwards via a central, bush-like bearing opening (12). This forms a first radial slide bearing (13). With its upper end (23), the standing axis (4) lies in a central, bush-like bearing opening (14) in the insert part (11), which is designed in the manner of a blind hole and forms a second radial sliding bearing (15) for the axial sliding bearing Spinning top (6)
  • a bearing ball (17) is held on the standing axis (4) at the closed inner end (16) of the bearing opening (14) with a press fit - that is to say self-locking - which is in a point-like metal-metal contact on the upper end face (18) of the standing axis ( 4) sits and thus forms an axial plain bearing (24) for the gyro body.
  • the insert part (11) has in its jacket area an annular oblique flank (19) and a radial annular projection (20) arranged circumferentially on its peripheral edge on the circumferential body side.
  • the insert part (11) is permanently connected to the tip part (9) by ultrasonic welding in these areas.
  • the gyro body (6) is thus supported downwards via the axial slide bearing (24) formed by the bearing ball (17) and the end face (18) of the standing axis (4).
  • a particularly intimate connection between the insert part (11) and the tip part (9) is achieved by the positive engagement of the inclined flank (19) and the ring projection (20) on the inner lateral surface of the tip part (9) and its complementary to the ring projection (20), circumferential ring shoulder (21) achieved.
  • a crimp (22) is attached to the standing axis (4), which protects the tip part (9) and thus the gyroscope body (6) from being pulled off the standing axis (4) .
