Description

[Detailed Description of the Invention] The present invention relates to a walking motion device for a doll that allows the doll's legs to move in a natural walking motion.

When a doll walks, it is necessary to lift one leg slightly in order to move it forward, and when this is repeated alternately, the doll's body sways from side to side, making the movement awkward.

This invention solves the above problem, and its purpose is to pivot the operating mechanism to which the left and right legs are attached to the doll's body so that it can swing left and right, and to move the left and right legs back and forth in accordance with the left and right swing. It is an object of the present invention to provide a walking motion device for a doll, which allows natural motions without shaking the body by having a structure that allows walking motions.

That is, in the present invention, the left and right legs 1 and 2, which move back and forth in accordance with the walking motion, are respectively attached to the mutually interlocking back and forth swing shafts 4 and 5 of the movement mechanism 3, and the movement mechanism 3 is installed in the doll body 6 so as to move back and forth. The guide arms 7 and 8 are movably supported on the back and forth swing shafts 4 and 5.
This walking motion device for a doll is characterized in that a tapered cam 9 is provided inside the doll body 6, and the tips of the arms 7 and 8 come into contact with each other to define the swinging motion of the motion mechanism 3.

To explain in more detail with the illustrated embodiments, 1, 2
4 and 5 are the right and left legs, 4 and 5 are front and back swing shafts that are pivoted to the operating mechanism 3, and each leg 1 and 2 is attached to be able to swing in the front and back direction. Fan-shaped leg position fixing plates 10 and 11 are fixed to each end,
Upper small holes 12, 13 and each leg 1, 2 made therein
The standing posture is maintained by the engagement of the projections 14, 15 provided on the projections 14, 15 and the fan-shaped leg position fixing plate 10,
The seat position is achieved by engagement with the lower small holes 10a, 11a of 11. Since the fixed plates 10 and 11 are parallel, the legs 1 and 2 are parallel even in the sitting position, making it stable. 1
6 and 17 are the stops 4a and 5a at each shaft end and each leg 1 and 2.
The spring inserted between the two is shown. Gears 18 and 19 are fixed to the inner ends of the longitudinal swing shafts 4 and 5 and mesh with each other within the operating mechanism 3. The operating mechanism 3 is pivotally supported by the doll body 6 so as to be able to swing from side to side by a shaft 20 extending through the casing 3a, and guide arms 7, 8 is fixed at the base. 7a,
Reference numeral 8a indicates a guide roll attached to the tip of each arm 7, 8 by shafts 7b, 8b. 9 is the operating mechanism 3
The tapered cams 9a and 9b that define the swinging motion of the cams are cam surfaces provided on both sides of the cams, and the guide rolls 7a and 8a move inward at the front by an amount corresponding to the taper of the planar tapered cam 9. Reference numeral 21 denotes a board into which the above operating mechanism 3 and tapered cam 9 are incorporated.

The doll with the above-mentioned structure is held from the back with the hand, and is made to walk by pushing it forward in an upright position.When one leg moves relatively backwards due to this operation, the other leg moves to the main body 6. Move forward without having to tilt. That is, as shown in FIG. 4, when the main body 6 is pushed slightly to the left and forward from the state where the right leg 1 is at the rear, the operating mechanism 3 swings to the right around the shaft 20 (solid line in FIG. 4). In addition, the right leg 1, which is engaged with and interlocked with the retreat of the left leg 2 by the gears 18 and 19, moves forward while slightly rising. During this time, the right leg 1 is separated from the tread surface by the movement mechanism 3 swinging to the right, and as it moves forward, the guide roll 7a retreats on the tapered cam surface 9a.On the other hand, the guide roll 8a on the left leg 2 side is moved from the cam surface. 9b moves forward, and as a result the positions of both rolls 7a and 8a change, the swinging (tilting) direction of the operating mechanism 3 also changes to the left, and this time the right leg 1 touches the ground and the left leg 2 leaves the tread and moves forward. He will be sent to

Therefore, according to the present invention, the operating mechanism 3 to which the left and right legs 1 and 2 are attached is pivotally supported on the main body 6 of the doll so that it can swing from side to side, and both legs 1 and 2 are moved in accordance with the left and right swinging.
Since the robot moves forward and backward in a linked manner, when you hold the main body 6 and push it forward, the movement mechanism 3 tilts and only one of the left or right legs 2, 1 touches the tread, while the other Only one of the legs 1 and 2 is separated from the tread surface and swung forward, and this action is repeated, so that the main body 6 can perform a natural running motion without inclining at all.
