Description

  The present invention relates to a walking toy. More specifically, the present invention relates to a walking toy that enables four-legged walking. In this specification, the four-legged walking is used as a term meaning walking other than the two-legged walking, and mainly refers to the four legs of the front bipod and the rear bipod. Includes four or more polypods including two or more dummy legs. Further, in this specification, the walking direction is referred to as the front-rear direction, the horizontal direction orthogonal thereto is referred to as the left-right direction (width direction), and the vertical direction is referred to as the up-down direction.

  Walking toys that allow four-legged walking have existed for some time, and some have a drive source while others do not. For example, a quadruped toy that does not have a drive source is equipped with two pendulum-like legs that swing back and forth in the front and rear, and the body swings back and forth and right and left by its own weight on the slope. There is one that moves while moving the left and right legs alternately in a pendulum shape while moving (Patent Document 1). In this walking toy, a pair of left and right leg portions are arranged in front and rear of the torso, and are supported so as to swing in a pendulum shape in the front-rear direction around a horizontal support shaft orthogonal to the traveling direction. By moving the center of gravity, the left and right legs are alternately advanced while the body is swung back and forth and left and right. In other words, if the toy's torso tilts to the right, the right leg does not move, but the left leg lifts slightly, so it moves forward in its pendulum shape due to its own weight, and if it tilts to the left, the left leg does not move, but the right leg Since the leg is slightly lifted, it moves forward in a pendulum shape by its own weight.

  In addition, as a quadruped walking toy equipped with a drive source, there is one that drives a front bipod and a rear bipod respectively using a drive mechanism that uses a power source such as a spring or a motor (patent) References 2 and 3). For example, in a quadruped walking toy having a front foot and a rear foot that are moved back and forth by swinging in a horizontal plane around a vertical support shaft, a connecting plate having foot portions at both ends is horizontally disposed and the center Is provided with a front foot and a rear foot that are supported by a shaft portion in the vertical direction and are swingable in the front-rear direction in a horizontal plane, while the front foot connection plate and the rear foot connection plate are opposite to each other, for example, on the front foot side A circle that is connected to the right side of the support shaft of the connecting plate and the left side of the support shaft on the rear foot by a connecting rod and is rotated by a drive motor by providing a long long hole in the left-right direction in the middle of the connecting rod. By engaging with the eccentric shaft on the plate, the connecting rod is moved back and forth by the rotation of the disk by the drive motor, and the front and rear legs are alternately swung horizontally in the front-rear direction around the support shaft. Walk with your forefoot and hindfoot in opposite directions in the horizontal plane Line toys have been proposed (Patent Document 2).

  Further, for example, in a quadruped walking toy including a front foot and a rear foot that are moved back and forth by swinging in a vertical plane around a horizontal support shaft, it swings in a pendulum shape in the front-rear direction with respect to the body portion. And a front leg member that moves up and down, and a rear leg member that rotates only in the front-rear direction. The front leg member and the rear leg member are linked by a link so that the first motor rotates in the opposite directions. The first drive mechanism that moves forward by alternately expanding or narrowing the front and rear legs in conjunction with the rear leg, and the back of the rear leg of the rear leg member rotates in a direction that intersects the direction of rotation of the rear leg member. A second drive mechanism that drives the wheels arranged in the opposite directions between the left hind leg part and the right hind leg part via the second motor and the direction changing mechanism, The motor is advanced by alternately expanding and narrowing the front and rear legs. At the same time, the rear part of the body part is alternately swung in the lateral direction (left and right direction) by forward and reverse rotation of the second motor so that the direction of the whole body part can be changed and the course can be changed (Patent Document 3). . In other words, by changing the direction to the left and right by alternately swinging the rear part of the body part in the horizontal direction (left and right direction) while moving forward, a change in the monotonous straight advance operation is made.

Japanese Utility Model Publication No. 36-10638 JP 2009-160238 A JP 2003-205180 A

  However, in the case of the toy described in Patent Document 1 in which the legs are moved alternately in the front-rear direction only by its own weight, and are slightly swung in the front-rear and left-right directions, the movement is monotonous, uninteresting and easy to get bored simply by moving straight forward. There is a problem. In addition, since it is necessary to walk using an inclined surface or tow using a weight, there is a problem that the place of play and play conditions are greatly restricted and the movement is slow. Moreover, if the inclination of the inclined surface is not increased or the weight is not heavy, the extension and back-and-forth movement of the legs will not be performed smoothly, but even if they are too large, they will be out of balance and fall easily, and the plane of the running surface Even when the degree cannot be secured and there is a bend or the like, there is a problem that it easily falls.

  In addition, in the quadruped walking toy described in Patent Document 2 provided with a driving source such as a motor, it is possible to move straight only by moving the front and rear legs symmetrically, and the movement is monotonous and lacks in interest and is easily bored. It will not change. In other words, there is a problem that the change in the movement of the toy is poor just because the walking time is long.

  Further, like the four-legged walking toy described in Patent Document 3, even if the movement can be changed by incorporating a direction changing mechanism, the body is obtained by forward and reverse rotation of the second drive motor that drives the wheels of the rear leg member. The rear part of the body is shaken sideways to change the direction of the torso and change the course, and it only changes direction periodically at a constant rhythm regardless of the intention of the child playing, so the movement of the toy spontaneously Lacks the fun of giving changes to In addition, the first drive mechanism that swings the front leg and the rear leg in opposite directions and in the front-rear direction, the first drive motor that drives the first drive mechanism, and the first wheel that drives the wheels on the sole of the rear leg member 3 are driven. Since the second drive mechanism and the second drive motor are required, the mechanism is complicated and the number of parts is increased, and it can be applied only to a relatively large toy, and can be provided as an inexpensive and simple toy. Can not. Moreover, it is difficult to provide a toy that is extremely small, lightweight, extremely simple in structure and hard to break.

  Furthermore, in any of the above-mentioned toys, the way of playing is simply to enjoy a monotonous straight movement or a walking action with periodic direction changes. Changes in characters, such as the fun of rearranging intended for character growth, transformation, transformation, etc., enjoyment of adding storylines through design changes, etc., and changing the quality of movement accompanying deformation / transformation It is not possible.

  An object of the present invention is to provide a toy capable of walking on four legs with a simple structure that enables downsizing. It is another object of the present invention to provide a walking toy that can be played on a horizontal plane without requiring an inclined surface or a weight, that moves quickly, and that does not fall easily. Furthermore, an object of the present invention is to provide a walking toy having a play element such as a rich change in the movement of the toy and enabling rearrangement.

  In order to achieve this object, the quadruped walking toy according to the first aspect of the present invention is arranged in a direction orthogonal to the traveling direction, and a pair of driving legs that are forcibly extended in the front-rear direction by the driving means. At least a pair of dummy legs swinging like a pendulum in the front-rear direction with its own weight around a horizontal support shaft, and walking by moving the dummy legs back and forth while swinging the body left and right and back and forth by driving the drive legs Like to do.

  Here, in the quadruped walking toy according to the present invention, the torso may be constituted by providing a driving leg with driving means and a dummy leg without a power source in one body, Each may be configured as a separate unit. For example, the fuselage is composed of a combination of a drive unit that incorporates drive means and drive legs, and at least one dummy unit that incorporates dummy legs, and the drive unit and the dummy unit are separable blocks that are independent of each other, The drive unit and the at least one dummy unit are arranged in the front-rear direction and are connected in the front-rear direction. At least one of the units is connected to be rotatable about the connection shaft, and the dummy unit arranged in the front side or It is preferable that the drive unit and the drive unit or the dummy unit arranged on the rear side rotate relative to each other about the connecting shaft so that the other unit is twisted with respect to one unit. Further, when a plurality of dummy units are provided, the dummy units are also connected to each other by a connecting shaft so that either unit can rotate around the connecting shaft.

  Further, in the four-legged toy according to the present invention, the connecting shaft is a unit that rotatably connects the dummy unit or driving unit arranged on the front side and the driving unit or dummy unit arranged on the rear side, or the connecting shaft is It is preferable that the dummy unit or driving unit arranged on the front side and the driving unit or dummy unit arranged on the rear side are connected to be separated from each other.

  In the quadruped toy according to the present invention, it is preferable that the front leg is shorter than the rear leg, or the front leg is longer than the rear leg and tilted forward or backward.

  Furthermore, the quadruped walking toy according to the present invention preferably includes a plurality of pairs of dummy legs.

  In the quadruped toy according to the present invention, the drive leg is preferably supported so as to be swingable in a pendulum shape in the front-rear direction around a horizontal support shaft arranged in a direction orthogonal to the traveling direction. .

  Here, the driving means in the quadruped walking toy according to the present invention is a gear box that uses a torsion coil spring as a power source, and includes a crank mechanism that engages with the driving leg in the front-rear direction, and an output that rotates the crank mechanism. A lever that rotates the drive gear of the gear train that transmits the rotation of the torsion coil spring to the shaft is arranged in the center of the left and right direction of the gear box, a torsion coil spring is arranged between the lever and the gear box, and the lever is pushed down. Thus, it is preferable that the torsion coil spring is twisted and the lever protrudes out of the body of the drive unit and is pushed down to wind up the torsion coil spring.

  In the above-mentioned gear box, one of the gears constituting the gear train is a run-up gear that revolves around the meshing gear closer to the drive gear, and the gear box runs when the torsion coil spring is wound up by operating the lever. It is preferable that the ascending gear be revolved to release the meshing with the gear of the meshing counterpart near the output shaft of the running gear so that the rotation of the gear train is not transmitted to the output shaft.

  According to the walking toy according to claim 1, since the body tries to swing left and right and back and forth by the driving legs that are forcibly extended in the back and forth direction, the dummy legs also move back and forth alternately in a pendulum shape. It is possible to walk on four legs as if the driving leg and the dummy leg are synchronized even though only one of the front leg and the rear leg is driven. Moreover, the dummy leg and the driving leg are completely separated from each other in power and do not have a linkage relationship, and the dummy leg and the driving leg move independently without being linked. There are few things. Further, since the dummy leg and the driving leg are completely separated from each other in power and there is no linkage relationship, the driving unit and the dummy unit can be separated and independent and connected to each other. In addition, since it is only necessary to provide the driving means on either the front leg or the rear leg, the mechanism can be simplified and made compact and the cost can be reduced. Further, since the mechanism can be simplified, it is difficult to break down and malfunction is unlikely to occur.

  According to the walking toy according to the invention described in claim 2, the drive unit and the at least one dummy unit, which are separable blocks independent from each other, are arranged at the front and back and at least the connecting shaft arranged in the front-rear direction. Either one of the units is connected so as to be rotatable about the connecting shaft, and the unit arranged on the front side and the unit arranged on the rear side rotate relative to each other about the connecting shaft. Since the other unit can be twisted, the dummy unit is twisted with respect to the drive unit around the connecting shaft, and the dummy unit is tilted. To do. Due to the inclination of the dummy unit, the part where the dummy leg is in contact with the floor surface contacts only on the right side or the left side of the vertical axis passing through the center of the connecting shaft that connects the front and rear units of the unit, or the degree of contact of either one Since it becomes larger than the other contact degree, it rotates toward the side where the dummy leg is in contact or the side where the contact degree of the dummy leg is large. That is, it rotates and turns in the direction with resistance or the direction with large resistance between the dummy leg and the floor surface. In addition, the degree of turning is proportional to the degree of twist between the front and rear units, so that the magnitude of turning can be adjusted. On the other hand, if the dummy unit and the drive unit are arranged straight without twisting, the toy moves substantially straight. Therefore, the walking direction of the toy can be freely set by changing the inclination of the dummy unit.

  In addition, since the drive unit and at least one dummy unit that are independent from each other are connected to each other by a connecting shaft so as to be separable, a combination of the drive unit and the dummy unit, or a combination of a plurality of dummy units, may be provided between them. The combination in can be changed freely. Thereby, the design of the toy composed of the drive unit and the at least one dummy unit can be changed. For example, a non-existing animal or the like can be created by combining the front half of the toy with a horse and the rear half with a cow. In other words, you can enjoy the rearrangement itself.

  According to the walking toy according to the invention described in claim 3, since the drive unit and the dummy unit, and further, the plurality of dummy units are combined by being directly connected by the connecting shaft, the distance between the dummy leg and the drive leg is narrow. It is an interesting toy because it can easily change the direction of travel due to slight changes in conditions such as floor friction and changes in the friction between legs and feet, and can cause unpredictable movement.

  In addition, according to the walking toy according to the present invention, the dummy unit and the drive unit are completely separated from each other in power and there is no linkage relationship, so that the drive unit and the dummy unit can be separated and connected. . Then, the dummy unit and the driving unit are separated by a long connecting shaft and connected to each other so that the toy of a long animal, for example, a dachshund, is extremely long between the dummy leg and the driving leg, that is, between the front leg and the rear leg. We can offer unique toys with motifs. In other words, the degree of freedom in toy design and play is increased simply by changing the connecting shaft. In addition, as the distance between the dummy unit and the drive unit increases, the straightness during straight advancement increases.

  According to the fifth aspect of the present invention, the front leg is made shorter than the rear leg, or the front leg is made longer than the rear leg so as to tilt forward or backward. Therefore, it is possible to walk faster and more stably than when the front leg and the rear leg have the same length. According to the experiments by the present inventors, the driving leg and the dummy leg can walk even with the same length, but it is faster and more stable to adopt a forward or backward tilting posture with different leg lengths in the front and rear. Turned out to walk. In addition, if the leg of the front unit is set longer than the leg of the rear unit, the toy inevitably takes a backward tilting posture, so that an interesting movement in which the toy moves backward can be realized. For example, in the case of a toy that represents a four-legged human infant or a four-legged non-human animal, you can enjoy an unprecedented interesting movement of a toy by dropping back and moving backwards.

  Further, according to the four-legged walking toy according to claim 6, since it is provided with a plurality of pairs of dummy legs, for example, a multi-legged walking such as a centipede by connecting a large number of units with dummy legs. It is also possible to make toys.

  Further, the walking toy according to the present invention has a difference in movement / running and stability depending on the number of dummy units to be connected and the difference in leg length. Therefore, the walking speed can be made to compete by changing various combinations of the drive unit and the dummy unit.

  According to the four-legged walking toy according to claim 7, the drive leg is supported so as to be swingable in a pendulum shape in the front-rear direction around a horizontal support shaft arranged in a direction orthogonal to the traveling direction. By alternately moving the legs back and forth with a quick movement so that both feet slide without leaving the floor, the connected drive unit and dummy unit try to swing left and right and back and forth. The four-legged walking can be performed as if the driving leg and the dummy leg are synchronized, although only one of the front leg and the rear leg is forcibly swung.

  According to the walking toy according to the eighth aspect of the present invention, the torsion coil spring is wound up simply by pushing down the lever, so that the toy can be operated with one hand while it is placed on the floor. In addition, the winding of the torsion coil spring is completed only by pushing the lever once, so that the winding is faster than winding the manual winding knob many times. And the operation of simply pushing down the lever while the toy is placed on the floor is a simple movement that is possible for an infant, so it becomes a toy that can be played by an infant. In addition, since the work of holding the toy once, winding the spring and then lowering it to the floor is unnecessary, the balance of the posture of the toy is not lost when the hand is released from the toy. In addition, since the center of gravity is originally in the center in the left-right direction and the bias of the center of gravity is small, it is difficult to break the balance of the posture of the toy at the time of walking, and the toy that is easy to play can be realized.

  In addition, the gear box hoisting operation means using a torsion coil spring as a drive source is arranged as a lever at the center in the left-right direction of the body of the drive unit, so the position of the center of gravity in the left-right direction of the walking toy is placed at the center. In addition, the balance of the center of gravity in the left-right direction, which is one of the factors inducing toy fall during walking, can be eliminated, and the balance during walking can be stabilized and difficult to fall. Moreover, since the position of the center of gravity in the left-right direction of the walking toy is arranged at the center, the influence of the center of gravity movement due to twisting between the front and rear units is increased, and the movement of the toy can be greatly changed. Therefore, by adjusting the twist between the front and rear units, various changes can be made to the movement of the toy. Moreover, even if the entire toy is made compact, it can give a variety of movements.

  In addition, compared to using a general spring drive unit, there is no need for a space that can accommodate a mainspring that expands in the radial direction, or a hand-wound knob that is large enough to be turned while picking with a fingertip. It is possible to reduce the size of the gear box as a driving source, and in turn to reduce the size of the toy body incorporating the gear box. Further, the cost is reduced by the torsion coil spring.

  According to the walking toy according to the invention described in claim 9, when the torsion coil spring is wound up by pushing down the lever, one of the gears constituting the gear train of the gear box is detached from the gear train, and the rotation of the gear train is performed. Is not transmitted to the output shaft, so the legs do not flutter and the toy can be operated with one hand while it is placed on the floor. That is, since the torsion coil spring can be wound up by simply pressing the lever while the toy is placed on the floor, the operation is also possible for an infant.

  Hereinafter, the configuration of the present invention will be described in detail based on embodiments shown in the drawings.

  1 to 6 show an embodiment of a quadruped toy according to the present invention. This four-legged toy 1 has a pair of drive legs 6 that are alternately forcedly swung back and forth by a driving means 8 and a horizontal support shaft 9 that is arranged in a direction orthogonal to the traveling direction, and that is its own weight. And at least a pair of dummy legs 10 swinging in a pendulum shape, and the dummy legs 10 are moved back and forth while forcing the drive legs 6 to swing left and right and back and forth to walk. .

  Here, the driving leg 6 having the driving means 8 and the dummy leg 10 having no driving means may be provided in one body, or may be configured as separate units. In the present embodiment, the driving leg 6 and the dummy leg 10 are detachably connected after being incorporated in separate bodies. Specifically, a bipedal driving unit 3 having a pair of driving legs 6 provided with driving means 8 and moving back and forth alternately and a pair of dummy legs 10 moving back and forth alternately without a power source are provided. One toy is composed of at least one dummy unit 4 for foot walking and a connecting shaft 5 that connects these units 3 and 4 in a separable manner.

  In the present embodiment, the drive unit 3 and the dummy unit 4 are separable blocks that are independent from each other, and are arranged at least one of the connecting shafts 5 that are arranged in the front-rear direction and arranged substantially horizontally in the front-rear direction. One unit is connected rotatably about the connecting shaft 5. That is, the unit arranged on the front side (dummy unit 4 or drive unit 3) and the unit arranged on the rear side (drive unit 3 or dummy unit 4) rotate relative to each other around the connecting shaft 5, and The other unit is configured to be twisted with respect to the unit. Therefore, if a twisting force is applied between the front and rear units, the other unit can be rotated with respect to one unit about the connecting shaft 5 and tilted in the left-right direction.

  For example, as shown in FIGS. 2 and 6, the connecting shaft 5 for rotatably connecting the front and rear units, for example, the dummy unit 4 and the drive unit 3 (or the dummy units 4), is connected to each unit 3, 4. A pair of bearings composed of semicircular recesses formed on the edges of the pieces 2a, 2b and 2a ', 2b', which are halved in the left-right direction (width direction) constituting the bodies 2, 2 ', are abutted. A shaft portion that is fitted in the holes 50 and 50 ′ and is rotatably supported, and a circular flange 51 that sandwiches the front and rear bodies 2 and 2 ′. That is, the connecting shafts 5 for connecting the front and rear units 3 and 4 are accommodated on the mutually opposing surfaces or contacting surfaces of the bodies 2 and 2 ′ of the drive unit 3 and the dummy unit 4 arranged in the front and rear. Holes 50, 50 'are provided. The holes 50 and 50 'are formed as bearings composed of semicircular recesses on the mating surfaces of the two pieces 2a and 2b and 2a' and 2b 'divided into two in the left-right direction (width direction). When the two pieces 2a, 2b and 2a ′, 2b ′ are closed, one hole is formed. On the other hand, the connecting shaft 5 is formed with flanges 51 orthogonal to the connecting shaft 5 at both ends, and is provided between the flanges 51 so as to sandwich the holes 50 and 50 ′ of the bodies 2 and 2 ′. Therefore, the gear box 8, the drive leg 6, the dummy leg 10, and the connecting shaft 5 are fitted between the two pieces 2 a, 2 b and 2 a ′, 2 b ′ and fastened with the fastening screw 20. It is provided so that.

  Further, in the case of this embodiment, the drive unit 3 includes a gear box using the torsion coil spring 25 as a power source as the driving means 8 (hereinafter referred to as the gear box 8), and moves back and forth alternately by the gear box 8. It is mainly composed of a pair of drive legs 6 and a body 2 incorporating the gear box 8 and the drive legs 6. The body 2 of the drive unit 3 is composed of, for example, two pieces 2 a and 2 b that are divided into two in the left-right direction (width direction), and a gear is provided between the two pieces 2 a and 2 b that are integrated with the fastening screw 20. The box 8, the drive leg 6, and the flange 51 at one end of the connecting shaft 5 are provided. Further, in the center of the back surface (rear side) of the body 2 of the drive unit 3, the lever 22 of the gear box 8 or the cover 49 covered by the lever 22 protrudes and can be moved vertically. The long groove 44 is formed. Each piece 2a, 2b is provided with a recess 46 for accommodating the gear box 8 and holding it at substantially the center of the body 2, and the pieces 2a, 2b are combined so as to sandwich the gear box 8 therebetween. To fix the gear box 8 to the center of the body 2. Further, since the driving leg 6 swings at the bottom of each piece 2a, 2b, a long groove 45 is formed in the body 2 in the front-rear direction.

  On the other hand, the body 2 ′ of the dummy unit 4 is composed of two pieces 2a ′ and 2b ′ that are divided into two in the left-right direction (width direction), and is connected to the dummy leg 10 between the two pieces 2a ′ and 2b ′. It is provided so as to be integrated with the fastening screw 20 after accommodating the flange 51 of the shaft 5. Here, the dummy leg 10 is accommodated so as to be swingable in the front-rear direction by a horizontal support shaft 9 suspended so as to cross the body 2 '. Specifically, with the cylindrical spacer 12 interposed between the pair of dummy legs 10, the horizontal support shaft 9 is passed through the upper hole 13 and the spacer 12, and the left and right pieces 2a ', 2b' The both ends of the horizontal support shaft 9 are fitted in the bearing holes 52 respectively. Further, a long groove 45 in the front-rear direction for swinging the dummy leg 10 is formed at the bottom of each mating surface of each piece 2a, 2b. When the dummy unit 4 is disposed on the front side as in the present embodiment, the dummy leg 10 is disposed on the relatively front side of the body 2 ′ so that the distance from the drive leg 6 of the rear drive unit 3 is increased. In order to obtain stability, it is preferable to make it as wide as possible. Also, since the dummy leg 10 swings at the bottom of each piece 2a ', 2b', the body 2 has a long groove 45 'formed in the front-rear direction.

  The bodies 2 and 2 ′ that accommodate the drive legs 6 and the dummy legs 10 are portions that become the torso of a walking toy, and are formed of, for example, a plastic injection molded product, for example, an animal that walks on four legs, for example, a human in quadruped Designs based on the motifs of infants and non-human animals, especially beasts, are engraved or printed. In the present embodiment, the body 2 of the drive unit 3 and the body 2 ′ of the dummy unit 4 are separately depicted or printed. In the present embodiment, the position of the dummy unit 4 is arranged so as to be on the front side in the traveling direction, and is irrelevant to the context of the toy design.

  In the present embodiment, the front unit and the rear unit have different body shapes and block shapes. This is not a special technical requirement, but merely a design requirement. That is, the front and rear end portions of the body block of the dummy unit on the front side are inclined corner portions, which are reminiscent of the constriction of the torso of a quadruped animal, or the head side image. The design is not limited to this, and the front and rear unit shapes may be the same or may be completely different depending on the case.

  Further, in the case of this embodiment in which the dummy unit 4 and the drive unit 3 are directly connected by the connecting shaft 5, at least the surfaces of the dummy unit 4 and the drive unit 3 around the connecting shaft 5 that are in contact with each other or the opposing surfaces are connected shafts. When the front unit and the rear unit are rotated relative to each other about the connecting shaft 5, the two units are slidably in contact with each other and are smoothly rotated. Yes. That is, the front unit and the rear unit may be in a relatively rotatable shape in the connected state, and may be, for example, a rectangular block, a non-rectangular block, or a spherical shape or An oval non-polygonal block may be used, and a favorite toy body design can be obtained. For example, when designing insects such as ants and bees, a constriction can be formed between the front unit and the rear unit.

   A gear box 8 using a torsion coil spring 25 as a power source is set at the center of the body 2 of the drive unit 3. As shown in FIGS. 10 to 13, the gear box 8 is disposed between a lever 22 that hooks one end 25 a of a torsion coil spring 25, an output shaft 35 that has a crank mechanism at both ends, and rotates between them. It consists of a transmission gear train for transmission or a constant speed mechanism provided as necessary, and a frame 36 for housing them. In the present embodiment, as shown in FIG. 11, the transmission gear train uses the gear 23 formed on the lever 25 as the first gear (drive gear), the second gear 27, the third gear 28, and the fourth gear 32. And a fifth gear 34 provided on the output shaft 35. Further, the gear box 8 of the present embodiment supports the shaft 29 of the third gear 28 with the long holes 30 and 31, thereby allowing the third gear 28 around the second gear 27 in the range of the long holes 30 and 31. Revolution is possible. Accordingly, when the lever 22 is pushed down and the torsion coil spring 25 is twisted, the rotation of the second gear 27 causes the third gear 28 to be caught in the rotation direction of the second gear and move in the elongated holes 30 and 31. Disconnected from the fourth gear 32. As a result, the rotational movement when the lever 22 is pushed down is interrupted by the third gear 28 and is not transmitted to the fourth gear 32 and the fifth gear 34, so that the output shaft 35 and hence the drive leg 6 do not move. That is, when the lever 22 is pushed down to wind up the torsion coil spring 25, the drive leg 6 does not move, so that the lever 22 can be pushed down while the toy 1 is on the floor. The second gear 27 includes a small gear 27 a that meshes with the drive gear 23 formed on the lever 22, a large gear 27 b that is coaxially disposed, and a shaft 26. The third gear 28 includes a small gear 28 a that meshes with the large gear 27 b of the second gear 27, and a large gear 28 b and a shaft 29 that are arranged coaxially. The fourth gear 32 includes a small gear 32 a that meshes with the large gear 28 b of the third gear 28, and a large gear 32 b and a shaft 33 that are arranged coaxially.

  As shown in FIGS. 11 to 13, the lever 22 has a disk portion 43 in which a drive gear 23 is formed on a part of its peripheral surface at the center of rotation, and a torsion coil spring 25 is provided inside the disk portion 43. A storage space 24 is provided. The lever 22 is rotatably supported between the left and right frames 36 a and 36 b by a shaft 39 that passes through the center of the disk portion 43. The torsion coil spring 25 is accommodated in the internal space 24 of the disk portion 43, is disposed around the shaft 39 that penetrates the space 24, and one end 25 b of the torsion coil spring 25 is accommodated in the internal space 24 that extends to the distal end side of the lever 22. The other end 25 a is provided so as to protrude from an opening 41 provided in the frame 36 outside the internal space 24 and to be brought into contact with an edge 42 of the frame 36 defining the opening 41. Thus, when the lever 22 is pushed down, the torsion coil spring 25 is twisted between the lever 22 and the frame 36. The frame 36 is formed by combining two frames 36a and 36b, and is provided so as to be divided into left and right at the center. The lever 22 is supported so as to be able to swing within a vertically extending range of a vertically long opening 37 formed at a central portion on the rear side of the frame 36 along the mating surfaces of the left and right frames 36a and 36b. The disk portion 43 of the lever 22 is formed with the drive gear 23 at an angle slightly wider than the swing range of the lever 22. In the present embodiment, the lever 22 is provided so that the portion protruding outside the gear box 8 is covered with a cover 49 and protrudes outside the body 2. Thus, care is taken so that the cover 49 looks like the tail of an animal. That is, when the dummy unit 4 and the drive leg unit 3 form an animal, various forms of covers simulating the tail are provided on the lever 22 so as to protrude from the body 2. .

  Crank mechanisms are provided at both ends of the output shaft 35 of the gear box 8 as shown in FIGS. The crank mechanism includes a disc 17 corresponding to a crank arm and a crank pin 18 provided eccentrically from the rotation center of the disc 17. The disc 17 is provided at both ends of an output shaft 35 protruding out of the gear box 8. Are accommodated in a recess 40 formed outside the frame 36 of the gear box 8. The crank pins 18 of the discs 17 arranged on the left and right sides of the gear box 8 are arranged so that their mounting angles are shifted from each other by 180 °, and are engaged with the vertically elongated holes 16 of the both drive legs 6 arranged along the gear box 8. It is provided to match. Accordingly, the left and right drive legs 6 are forcibly swung in opposite directions, that is, alternately in the front-rear direction as the output shaft 35 rotates.

  A pair of drive legs 6 are swingably attached to the outside of the gear box 8 by pins 19 protruding in the left-right direction. That is, the drive leg 6 is supported so as to be swingable in a pendulum shape in the front-rear direction around a pin 19 that is a horizontal support shaft arranged in a direction orthogonal to the traveling direction. The pin 19 is inserted into the hole 14 at the top of the drive leg 6 so that the drive leg 6 is supported so as to be swingable in the front-rear direction. A portion of the drive leg 6 that interferes with the shaft 39 of the lever 22 is provided with an arc-shaped elongated hole 15 that is horizontally long in the front-rear direction, and the shaft 39 and the bearing portion pass through the elongated hole 15. The shaft 39 is provided so as not to interfere. Further, a longitudinal elongated hole 16 is formed in a portion of the drive leg 6 that intersects with the crank pin 18, and the crank pin 18 is fitted into the elongated hole 16 portion so as to be engaged in the front-rear direction. Therefore, when the disc 17 rotates, the crank pin 18 moves in the longitudinal direction in the long hole 16 of the drive leg 6, while the pin 19 serving as a horizontal support shaft disposed in the direction orthogonal to the traveling direction of the drive leg 6. It is driven in the front-rear direction like a pendulum in the front-rear direction.

  The drive leg 6 has a foot 7 at its lower end. In the present embodiment, the drive leg 6 and the foot 7 are integrally formed, but the drive leg 6 and the foot 7 that are independent of each other may be assembled and integrated. For example, a bifurcated connecting portion is formed at the lower end of the drive leg 6, and the connecting portion is inserted into a hole provided in the foot portion 7, and then a shaft passing through the hole passes through the bifurcated connecting portion. In such a manner, they may be connected so as to be swingable and detachable. In this case, only the foot 7 can be easily replaced. By changing the foot 7, the movement of the toy can be easily changed.

  The foot portion 7 is formed in a curved surface in which a surface in contact with the floor surface (hereinafter referred to as the sole of the foot) is gently curved at least in the swinging direction and the front-rear direction, and the floor surface and both foot portions 7 are always in contact with each other. The two drive legs 6 and the foot 7 are provided so that they can stand upright. For example, as shown in FIG. 14, a curved surface having a center of curvature on the vertical axis 47 passing through the center of swinging of the leg (center of the hole 14), that is, the front side and the rear side of the vertical axis 47 are symmetrical. It may be a foot 7 having a curved sole. Further, the soles of the driving legs 6 are also curved in the width direction (left-right direction) so as not to disturb the swinging of the driving unit in the left-right direction. In the case of this embodiment, as shown in FIGS. 15 and 16, it is formed on a curved surface that is symmetrical to the left and right, and further, a grip with the floor surface is required to some extent. It is provided to be a little more than the soles.

  On the other hand, since the dummy leg 10 is simply suspended from the horizontal support shaft 9 and moves back and forth in a pendulum shape, the vertical elongated hole 16 intersecting with the crank pin 18 of the crank mechanism and the shaft 39 of the gear unit as the driving means are used. The oblong arc-shaped long hole 15 for avoiding the interference with the antenna is not required, but it is not necessary to have a separate design. Therefore, in this embodiment, only the drive leg 6 and the leg length are changed to have the same structure. What has been adopted. The same applies to the foot portion 11, and like the foot portion 7 of the drive leg 6, the sole is formed in a curved surface that is gently curved at least in the swinging direction and the front-rear direction. 11 is provided so as to always contact. However, in the case of this embodiment, the curved surface in the width direction of the sole is left and right so that the surface contacting the floor surface is less than the sole of the driving leg 6 as much as possible and that it is easy to leave the floor surface when tilted. It is formed on an asymmetric curved surface. For example, as shown in FIGS. 15 and 16, the foot portion 11 of the dummy leg 10 is a curved surface having a relatively steep rise angle on the outside from the center line passing through the center of the leg when viewed from the front. Is formed asymmetrically so as to be a relatively gentle curved surface. Of course, the shape of the sole of the dummy leg 10, particularly the curved shape in the width direction, is not limited to that shown in FIGS. 15 and 16.

  In the present embodiment, the front leg is the dummy leg 10 and is shorter than the driving leg 6 serving as the rear leg so that the driving unit 3 and the entire toy are tilted forward. However, the present invention is particularly limited to this. It is not a thing. For example, the front leg may be the drive leg 6 and the rear leg may be the dummy leg 10 as shown in FIG. 18C or 18D, or the rear leg may be shorter than the front leg as shown in FIG. The drive unit 3 and the entire toy are tilted backward, or the drive unit 3 is tilted forward or backward by changing the position of connection with the connecting shaft 5 as shown in FIG. 18B or 18C. You may make it do. According to the experiments by the present inventors, the driving leg 6 and the dummy leg 10 can walk with the same length regardless of which is the front leg or the rear leg. I was able to move better (walk fast and stably). That is, the dummy leg 10 may be longer or shorter than the driving leg 6 and may be the same length, but it is preferable that the driving unit 3 is set to tilt forward or backward. In the case where two or more pairs of dummy legs 10 are provided, the relationship between the lengths of the legs is not particularly limited. However, when a plurality of pairs of dummy legs 10 are used, such as a centipede, one by one. It is preferable that the lengths are different, and it is preferable that the lengths be shorter toward the front or rear.

  7 to 9 show another embodiment. The four-legged walking toy 1 according to this embodiment is obtained by connecting a drive unit 3 and at least one dummy unit 4 with a long connecting shaft 5. In the toy of the present invention, there is no drive system connection relationship between the front unit, for example, the dummy unit 4 and the rear unit, for example, the drive unit 3, so the long connecting shaft 5 is separated from the dummy unit 4 and the drive unit 3. Can be connected. The long connecting shaft 5 is provided with a pair of flanges 51 that sandwich the periphery of the bearings on the periphery of the holes 50 and 50 'for fitting the connecting shafts 5 of the respective units at both ends, respectively. Each unit is rotatably connected. Therefore, a twist can be applied between the front unit and the rear unit. Such a connection form is useful when taking a form like a dachshund, for example, in order to form a long trunk part. In this case, the body 2, 2 ′ itself may be decorated with the connecting shaft 5 exposed, but it is not particularly limited, and the body 2, 2 ′ is covered with another exterior. It is also possible to have a desired appearance with the connecting shaft 5 hidden. In the present embodiment in which the dummy unit 4 and the drive unit 3 are separated and connected, the dummy unit 4 and the drive unit 3 are not in direct contact with each other. However, at least the surface sandwiched by the flange of the connecting shaft needs to be a plane orthogonal to the connecting shaft 5.

  According to the walking toy configured as described above, the body 2 tends to swing left and right and back and forth by the drive legs 6 that are alternately extended back and forth, so that the dummy legs 10 are also swung back and forth alternately. The four-legged walking can be performed as if the driving leg 6 and the dummy leg 10 are synchronized, although only one of the front leg and the rear leg is driven. In addition, according to the walking toy of the present invention, the dummy leg 10 and the driving leg 6 are completely separated from each other in a dynamic manner, so that the dummy leg 10 and the driving leg 6 are not linked. Because they exercise independently, they rarely fall out of balance. Further, if the dummy unit 4 and the drive unit 3 are arranged straight without twisting, the toy moves substantially straight. In particular, when the dummy unit 4 and the drive unit 3 are separated and connected by the long connecting shaft 5, the straightness is excellent.

  Here, when the front side is the drive unit 3 and it is tilted forward, it moves forward (see FIG. 18A), and when it is tilted backward, it moves backward (see FIG. 18B). Further, when the rear side is the drive unit 3 and is tilted forward, it moves forward (see FIG. 18C), and when it is tilted backward, it moves backward (see FIG. 18D). That is, the toy of the present invention moves either when the drive unit 3 is forward or backward relative to the traveling direction, and more when the drive unit 3 is tilted. Further, even if the drive unit 3 is on the front side, the drive unit 3 is on the rear side, and the drive unit 3 and thus the toy advances in the tilting direction. Of course, even if the drive unit 3 is not tilted forward or backward, the drive unit 3 moves in the traveling direction indicated by the toy drive unit 3.

  15 or 16, when the dummy unit 4 is twisted with respect to the drive unit 3 and the dummy unit 4 is inclined, the portions 55 where the dummy legs 10 are in contact with the floor surface 54 are the units before and after the unit. Since the contact is made only on the right side or the left side of the vertical shaft 53 passing through the center of the connecting shaft 5 that connects 3 and 4, or the contact degree on one side is larger than the contact degree on the other side, the dummy leg 10 It rotates toward the side where the contact is made or the contact degree of the dummy leg 10 is large. That is, the dummy leg 10 and the floor 54 are rotated and turned in a direction having a resistance or a direction having a large resistance. As a result, the toy 1 moves forward while turning toward the inner side where the dummy unit 4 is inclined. In addition, the degree of turning is proportional to the degree of twist between the front and rear units, so that the magnitude of turning can be adjusted. Therefore, the walking direction of the toy can be freely set by changing the inclination of the dummy unit. Incidentally, even when the dummy unit 4 is greatly inclined and only one leg is in contact with the floor 54, the dummy leg in contact with the floor 54 slips and the dummy leg / foot on the floating side swings. Move. That is, while the dummy leg 10 in contact with the floor 54 is sliding and moving, the floating dummy leg 10 is swaying and moving, so that the driving leg 6 and the dummy leg 10 are synchronized. Looks like he is walking on four legs. Even when the dummy unit 4 is disposed behind the traveling direction and tilted, it turns in the tilting direction.

  In addition, the toy 1 has at least four feet of at least one dummy unit 4 and the drive unit 3 or a pair of feet 7 of the drive leg 6 and their pairs when the toy 1 is tilted or straight, and when turning. Since it walks with three legs with the dummy leg 10 which touches the floor 54 in between, the balance of the toy 1 in the front-back and left-right directions is taken, and it becomes difficult to fall down during walking.

  Furthermore, since the position of the center of gravity of the toy 1 is substantially on the central axis, it is easy to give a change due to the twist between the front and rear units 3 and 4.

  Further, since the dummy unit 4 and the drive unit 3 are only rotatably connected to each other only by the connecting shaft 5, they can be freely exchanged and combined with other toy units. For example, it is possible to play with various animals such as a horse toy unit in the front unit and a cow toy unit in the rear unit. In other words, it is possible to play by changing the shape of the toy by exchanging the units. In addition, two or more dummy units having dummy legs can be connected as necessary, thereby making it possible to produce multipods such as centipedes.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described embodiment, the driving unit 3 including the driving leg 6 and the driving means 8 and the at least one dummy unit 4 including the dummy leg 10 are connected to each other so as to be rotatable. The pair of driving legs 6 and the dummy legs 10 may be provided as a front leg or a rear leg in one body unit 2 ′, and in some cases, a pair of driving legs 6 and a plurality of pairs may be provided. The dummy leg 10 may be provided. In any case, the dummy leg 10 can move back and forth in a pendulum manner as the body 2 ′ is shaken by the drive leg 6. Since it is possible to provide two or more pairs of dummy legs in this way, it is possible to make a multi-legged toy such as a centipede, and more than one dummy leg can be formed with one drive leg. Multi-legged walking can be performed as if synchronized.

  In the above-described embodiment, the gear unit 8 using a torsion spring as a power source has been described as an example of the driving unit of the driving unit 3. However, the present invention is not particularly limited thereto, and a general hairspring spring is not limited thereto. The present invention can be implemented even with a drive unit that rotates a crank pin of a crank mechanism using a gear unit or motor as a power source.

  In the present embodiment, the body 2 and 2 'itself is decorated and used as an exterior. However, the present invention is not particularly limited to this, and the body 2 and 2' may be covered with another exterior to obtain a desired appearance. Is also possible.

  In the above-described embodiment, the front side is the dummy unit 4 and the rear side is the drive unit 3. However, the present invention is not particularly limited to this, and the front side may be the drive unit 3 and the rear side may be the dummy unit 4. Further, the leg of the front unit is made shorter than the leg of the rear unit so that the drive unit 3 is tilted forward. However, the present invention is not particularly limited to this. It may be longer than the leg of the side unit and the drive unit 3 may be tilted backward.

  Further, in the above-described embodiment, the bipedal walking drive unit 3 and the bipedal walking dummy unit 4 are detachably coupled by the coupling shaft 5 in a state where the bipedal walking dummy unit 4 is arranged at the front and rear and rotate around the coupling shaft 5. One toy is configured so as to allow twisting between the units 3 and 4, but this is not particularly limited, and the drive unit 3 and the dummy unit 4 can be separated independently from each other. The blocks may be integrated by connecting in the front-rear direction with the connecting shaft 5. Even in this case, the excitement that the shape of the toy can be changed by exchanging the unit with another unit of the previous or subsequent unit is not impaired at all. In addition, as if the driving leg 6 and the dummy leg 10 are synchronized, the four-legged walking is interesting, the balance is less likely to fall over the balance, and the driving unit 3 and the dummy unit 4 are separated from each other. It is possible to connect, the mechanism can be simplified and made compact, the cost can be reduced, the mechanism can be simplified, so that it is difficult to break down, and further malfunctions are unlikely to occur. It does not impair various effects. Similarly, even if the product lineup that changes the form of toys by changing each unit is not complete, or even if the front and rear units are not separably connected by the connecting shaft 5, Obviously, it does not detract from the various effects.

  Further, the drive leg in the present embodiment is supported so as to swing in a pendulum shape in the front-rear direction around a horizontal support shaft, that is, a pin 19 arranged in a direction orthogonal to the traveling direction, so that both feet are not separated from the floor surface. However, the present invention is not particularly limited to this. In order for the walking doll to move forward while swinging from side to side, it is preferable that the ground contact surface of the sole is small and the leg moves fast. However, it is not necessarily limited to those with a small contact surface on the sole, and even if the sole has a wide contact surface, it may not be a leg that moves back and forth alternately so that the sole slides without leaving the floor. The four legs can be walked while moving the dummy leg back and forth. For example, it is a drive leg that has a foot shape that has a wide contact surface, for example, a U-shaped foot that is arranged so as to mesh with each other from the left and right and moves forward on the same trajectory / straight line alternately However, even when the right foot and the left foot are stepped alternately, the torso swings to the left and right, so that the dummy legs can alternately move in the back-and-forth direction.
