toy

The innovation relates to a toy running on a running rail in the form of a figure, in particular a fairy tale figure with a trunk and two legs.

Toys are already known »in which two are in a row arranged shapes each have two legs pivotable between two positions in the running direction. A The thread attached to the toy has a ti.so.hrand hanging Gewioht. When walking, the figures perform a pendulum movement across your walking direction, which means that only one one behind the other is at a time Pair of legs is loaded and swings backwards while the other pair moves forward freely. With this toy Bind, however, there are four swiveling units Legs necessary. ■

In addition, toys are known that run on an inclined running rail '-' * with the toy carrying rollers, from one of which, preferably the front one, is mounted eccentrically on the toy. When walking down through the running rail the toy makes a nodding movement. The disadvantage here is that the toy does not make a striding movement.

The task of the innovation is a toy that has one step movement executes, which according to the new invention is achieved by

.- ■ 2 -

that the front leg is rigid with the torso and the rear leg can be pivoted between two positions in the running direction Trunk is arranged »being in one position! in the the legs are close together, the focus of the Trunk close behind the vertical duroh the point of support of the hind leg - and in the other position, ~ at " the legs are spread "the center of gravity lies between the support points of the legs."

The mode of action and an embodiment is based on figures explained * It aeigen

Fig # 1 is a basic representation of the sequence of movements,

Fig. 2 shows an embodiment. ·

The toy consists of an inclined Lauf.schiene 1 with a U-profile »where the slope is about 5 °» The figure is placed on this rail, which consists of a trunk 2, a forefoot 4 rigidly connected to the trunk and a swiveling rear foot 3 arranged on the torso, which is rotatably mounted at D »consists» The center of gravity S is above the pivot point D * If the toy is placed on the rail 1 * with the legs 3 and 4 standing close together (position AB-) Center of gravity S ₁ just behind the vertical 1 through the support point A _{1 of} the hind leg 3. The trunk with the fore leg thus rotates around the pivot point D and at the same time the hind leg J pivots forward around its support point A ₁ * In fig. 1 this phase of movement is illustrated _{by the position A 1} D _{2 C when the front leg is lifted.} The center of gravity S-, which is located behind the support point A ^, now comes to lie in front of this support point au (position S ₂ ). This causes the torso and the front leg to tilt forward and down (position A ₁ DjB ₂ ) * on impact

of the foreleg in position B ₂ on the rail, due to the kinetic energy of the front leg and torso, rotates forward around point B ₂ , which briefly relieves the load on the hind leg and lifts it off the rail and thereby moves forward from position A- to the Position A ₂ pivots. In the new position A ₂ DJJ ₂ , the center of gravity S. is again behind the support point A ₂ # so that a new step movement is possible. . ^: ;> .

From the above it follows that the center of gravity must lie closely behind the vertical L. At the same time, it must lie within a circle K, which has its center in D ₂ (position A-jDgO) and touches the vertical L. It is most favorable when the center of gravity S lies close behind the vertical L on the circle K, since this is the safest way to perform the dynamically caused tilting movement from the position S to the position S. due to the long lever arm between the center of gravity and the support point B will"

In one embodiment, it has proven to be advantageous if the angle A ₁ D ₁ B _{1 is} approximately 20 ° and the angle A ₁ D ₇ B _{0 is} approximately 45. A tendency .the, track of about 5 was this low · The support surface ^ of legs on the Sohiene should be crowned "The rail with an OB-profile can be straight or" helical.
