  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of the walking toy 10. The walking toy 10 according to the present embodiment imitates a dog. Inside the walking toy 10, a drive mechanism 30 for walking the walking toy 10 is provided. The drive mechanism 30 rotates the left and right rotary foot members 31 and 32 that are front legs. The left and right hind legs 11 are provided on the trunk portion of the walking toy 10 so as to be freely slidable. A tongue member 17 projects from the mouth of the walking toy 10, and a tail member 21 projects from the rear end of the trunk. The tongue member 17 and the tail member 21 are swung in accordance with the operations of the left and right rotary foot members 31 and 32.

  Next, the drive mechanism 30 will be described with reference to FIGS. As shown in FIG. 2, the drive mechanism 30 is formed as a housing of the drive mechanism 30 by combining a left side plate 41 and a right side plate 42 with a boss or the like (not shown) at a predetermined interval. A motor 43 serving as a driving source that outputs a rotational driving force is provided on the upper portion of the casing. A battery case 44 serving as a power source for the motor 43 is provided below the motor 43. The motor 43 and the battery case 44 are appropriately fixed to the left side plate 41 and the right side plate 42.

  A worm gear 33 is fixed to the rotating shaft of the motor 43. A worm wheel 34 that meshes with the worm gear 33 is provided below the worm gear 33. The worm wheel 34 is connected to the pinion gear 36 via the clutch means 35. Between the left side plate 41 and the right side plate 42, a support shaft 37 pivotally supported by the left side plate 41 and the right side plate 42 is rotatably provided. The pinion gear 36 is fixed to the support shaft 37. The worm wheel 34 is axially movable with respect to the support shaft 37 and is rotatably supported.

  The clutch means 35 includes a drive source side member 35a fixed to the worm wheel 34, a gear side member 35b fixed to the pinion gear 36, and a coil spring 35c. The drive source side member 35a is movable in the axial direction with respect to the support shaft 37 and is rotatably supported. On the end surface of the drive source side member 35a, a protrusion 35a1 having a triangular cross section is formed in a cross shape in a side view. On the other hand, the gear side member 35 b is fixed to the support shaft 37. On the end surface of the gear side member 35b, a cross-shaped groove 35b1 is formed in correspondence with the protrusion 35a1 to engage with the protrusion 35a1.

  A coil spring 35 c wound around the outer periphery of the support shaft 37 is provided between the worm wheel 34 and the left side plate 41. The drive source side member 35a is urged together with the worm wheel 34 toward the pinion gear 36 by the coil spring 35c. In the steady state, the protrusion 35a1 and the groove 35b1 are engaged, and the drive source side member 35a is pressed against the gear side member 35b by the coil spring 35c. Accordingly, the rotational driving force of the motor 43 is transmitted from the worm wheel 34 to the pinion gear 36 via the clutch means 35.

  On the other hand, if the operation of the left and right rotary foot members 31, 32 is forcibly stopped for some reason and the rotation of the pinion gear 36 is prevented, the projection 35a1 resists the biasing force of the coil spring 35c. Gets over the groove 35b1 and the engagement between the two is released. As a result, the worm wheel 34 and the drive source side member 35a are idled, so that an overload of the motor 43 is prevented.

  In the present embodiment, the clutch means 35 is constituted by the engagement of the projection 35a1 and the groove 35b1, but other clutch means, for example, a clutch means using a friction plate may be used.

  A first gear 38 that meshes with the pinion gear 36 is provided below the pinion gear 36. The first gear 38 is rotatably supported by the right side plate 42. A second gear 39 that meshes with the first gear 38 is provided below the front side of the first gear 38. The second gear 39 is fixed to a walking rotation shaft 45 that is rotatably provided between the left side plate 41 and the right side plate 42.

  Thus, the worm gear 33, the worm wheel 34, the clutch means 35, the pinion gear 36, the support shaft 37, the first gear 38, and the second gear 39 are used to transmit the rotational driving force of the motor 43 serving as a driving source. A transmission part is formed.

  The walking rotation shaft 45 is rotatably supported by the left side plate 41 and the right side plate 42. Note that the walking rotary shaft 45 is supported by the left side plate 41 by supporting the outer periphery of the cam portion 60 by a plate 41a inserted into the cutout portion of the left side plate 41, as shown in FIG. . As shown in FIG. 2, a left rotating foot member 31 and a right rotating foot member 32 are provided at both ends of the walking rotation shaft 45 and outside the left side plate 41 and the right side plate 42, respectively. The left rotating foot member 31 is fixed to the walking rotation shaft 45 via a rotation position adjusting means 50 described later. On the other hand, the right rotation leg member 32 is directly fixed to the walking rotation shaft 45. A left retainer 31a and a right retainer 32a fixed to the walking rotary shaft 45 are provided on the outer sides of the left rotating foot member 31 and the right rotating foot member 32, respectively, so that the left and right rotating foot members 31, 32 are prevented from coming off. Has been.

  As shown in FIGS. 3 and 4, the outer shapes of the left and right rotary foot members 31 and 32 are perpendicular to the disc-shaped base portions 31b and 32b and the axis of the walking rotation shaft 45 from the base portions 31b and 32b. It consists of feet 31c, 31d, 32c, and 32d that protrude in the direction and come into contact with the walking surface. The foot portions 31c and 32c and the foot portions 31d and 32d are formed at two locations facing each other with respect to the axial center of the walking rotation shaft 45. The left and right rotary foot members 31, 32 formed in this way are rotated by the walking rotation shaft 45.

  That is, when the rotational driving force is output from the motor 43 via the motor shaft, the worm gear 33 is rotated. Then, the worm wheel 34 that meshes with the worm gear 33 is rotated. Then, the pinion gear 36 connected coaxially with the worm wheel 34 via the clutch means 35 is rotated. The rotational driving force of the pinion gear 36 is transmitted to a first gear 38 that meshes with the pinion gear 36. The second gear 39 that meshes with the first gear 38 is rotated by the rotation of the first gear 38. When the second gear 39 is rotated, the walking rotary shaft 45 and the left and right rotary foot members 31 and 32 are rotated.

  In addition, the power transmission part and the motor 43 are comprised so that the rotation direction of the rotating shaft 45 for walking and the rotation leg members 31 and 32 on either side may rotate to the direction shown by the arrow of FIG.3 and FIG.4. Accordingly, the walking toy 10 walks with the left and right foot portions 31c and 32c and the foot portions 31d and 32d facing each other alternately contacting the walking surface. And when one leg part 31c, 32c is the state exposed outside from the trunk | drum part of the walking toy 10, the other leg part 31d, 32d is accommodated in the trunk | drum part of the walking toy 10, and is concealed. It becomes a state. Therefore, since it seems that the left and right forefoot always come out one by one from the outside of the walking toy 10, the walking toy 10 can be made without any sense of incongruity.

  Next, the rotational position adjusting means 50 will be described. The rotation position adjusting means 50 is provided inside the left rotation foot member 31 and is formed so as to relatively adjust the rotation positions of the left and right rotation foot members 31 and 32 around the walking rotation axis 45. Specifically, an annular shape in which a plurality of concave and convex portions are continuously formed inward in the vertical direction with respect to the axis of the walking rotation shaft 45 around the rotation shaft 45 for walking inside the left rotation foot member 31. An uneven portion 51 is provided. Twelve concave portions of the annular concavo-convex portion 51 are formed. A substantially disc-shaped engagement member 52 that is fixed to the walking rotary shaft 45 is provided inside the annular uneven portion 51.

  The engaging member 52 is provided with two engaging protrusions 52 a that protrude outward from the outer periphery thereof so as to face the rotating shaft 45 for walking. A hole 52 b is provided on the inner side of each engagement protrusion 52 a in the engagement member 52 so as to repel each engagement protrusion 52 a vertically outward with respect to the axis of the walking rotation shaft 45. Therefore, each engagement protrusion 52 a is engaged with the recess of the annular uneven portion 51. In addition, if the engaging member 52 is formed of a resin material, each of the engaging protrusions 52a is more suitably bulleted by each hole 52b.

  The rotational position of the left rotating foot member 31 relative to the right rotating foot member 32 can be adjusted by the rotational position adjusting means 50 formed in this way. Specifically, the walking rotation shaft 45 is fixed so as to hold the right rotation foot member 32 with one hand. Then, the left rotating foot member 31 is rotated around the walking rotation shaft 45 with the other hand. Then, each engagement protrusion 52a gets over the protrusion of the annular uneven part 51 against the elastic force of each hole 52b and engages with the adjacent recess. And since the 12 recessed parts of the cyclic | annular uneven | corrugated | grooved part 51 are formed, the left rotation leg member 31 can be rotated 30 degree | times at a time.

  Here, FIG. 5 shows a state in which the rotational positions of the left and right rotary foot members 31 and 32 are adjusted. FIG. 5A shows a state in which the left and right rotary foot members 31 and 32 are aligned at their rotational positions without a phase difference. FIG. 5B shows a state in which the engagement between each engaging protrusion 52a and the concave portion of the annular concavo-convex portion 51 is shifted by one from the state of FIG. In this case, the left and right rotary foot members 31 and 32 have a phase difference of 30 degrees. FIG. 5C shows a state shifted from the state of FIG. 5B by two. In this case, the left and right rotary foot members 31, 32 have a phase difference of 90 degrees.

  As shown in FIG. 5A, when the walking toy 10 is walked in a state where the left and right rotating foot members 31 and 32 have their rotational positions aligned with no phase difference, padding is performed with the left and right forefoot aligned. The left and right rotary foot members 31, 32 are rotated. Then, the walking toy 10 walks as if jumping with its forefoot. As shown in FIG. 5B, when the rotation positions of the left and right rotary foot members 31 and 32 are set with a phase difference of 30 degrees, the right side is followed by the foot portion 31c (31d) of the left rotary foot member 31. The foot 32c (32d) of the rotating foot member 32 is grounded to the walking surface. Then, the walking toy 10 operates so as to perform a gallop operation, and turns to the direction of the foot 32c (32d) to be grounded later, that is, to the right.

  If the phase difference is 60 degrees instead of the 30 degree phase difference shown in FIG. 5B, the turning radius can be increased. Further, the phase difference can be changed so that the foot portions 31c and 31d of the left rotating foot member 31 are grounded to the left side following the foot portions 32c and 32d of the right rotating foot member 32.

  Further, as shown in FIG. 5C, when the rotational positions of the left and right rotating foot members 31, 32 are set with a phase difference of 90 degrees, the left and right foot portions 31c, 31d, 32c, 32d are alternately arranged. Grounded on the walking surface. Then, the walking toy 10 will walk while greatly shaking the body from side to side. In this way, the walking toy 10 can change the state of walking.

The rotating cylinder portion 64 is formed in a cylindrical shape, and a fulcrum shaft is inserted through the inside thereof. The fulcrum shaft is formed as a fixed fulcrum 64 a (see FIGS. 3 and 4) that is fixed across the left side plate 41 and the right side plate 42. Therefore, the rotating cylinder part 64 is rotatable around the fixed fulcrum 64a. And the tail member 21 used as a modification member is being fixed to the center part of this rotation cylinder part 64. As shown in FIG.

  A first operating rod 63 that is formed in an elongated shape in the front-rear direction is provided at the end of the rotating cylinder portion 64 on the left side plate 41 side. A first cam follower 63 a is formed at the end of the first operating rod 63. Since the first cam portion 61 protrudes larger from the inner surface of the left rotating foot member 31 than the second cam portion 62, the first cam follower 63 a does not contact the second cam portion 62, and the first cam portion Abuts only 61.

  In this way, as shown in FIG. 4, the first operating rod 63 is provided with the tail member 21 as a modifying member on one end side with the fixed fulcrum 64a in between, and the first cam on the other end side.

A second cam follower 65a is formed at the end of the second operating rod 65 in a pin shape outward. Then, a spring or the like that biases the second operating rod 65 upward is provided so that the second cam follower 65a is brought into contact with the first cam portion 61 and the second cam portion 62 from below. In this way, the second operating rod 65 is provided with the tongue member 17 serving as a modifying member on one end side with the fixed fulcrum 66a interposed therebetween, and the first cam portion 61 and the second cam portion on the other end side. A second cam follower 65a is provided in contact with 62 from below.

  The operation of the tongue member 17 and the tail member 21 is the first through the first cam followers 63a of the first operating rod 63 by the two first cam portions 61 when the left rotating foot member 31 rotates in the direction of the arrow in FIG. The actuating rod 63 is peristally moved. On the other hand, the second cam follower 65a is brought into contact with both the first cam portion 61 and the second cam portion 62, and the second operating rod 65 is caused to swing. That is, the tail member 21 is swung every time the walking rotary shaft 45 rotates 180 degrees. The tongue member 17 is oscillated every time the walking rotary shaft 45 rotates 60 degrees.

  In this way, the tongue member 17 and the tail member 21 that are the modifying members are swung at different timings, so that an infant playing with the walking toy 10 can further enjoy. Further, if the walking toy 10 is placed in a sitting posture with the buttocks and the tail member 21 of the walking toy 10 grounded to the floor and the front legs are floated, the left and right sides of the walking toy 10 are vibrated back and forth while the body is vibrated back and forth. The tongue members 17 can be swung by rotating the rotary foot members 31 and 32. In this case, the walking toy 10 can be played by performing a so-called “chinching operation”.

  Further, as shown in FIG. 4, a power supply extending portion 63 c extending downward from the lower side of the first operating rod 63 is formed on the first operating rod 63 below the curved extending portion 63 b.
