Description

  The present invention relates to a small-sized walking toy, and more particularly to a switch mechanism for controlling a walking operation of the walking toy.

  The present applicant has proposed and provided a walking toy as a small-sized walking toy, which is entirely reduced in size without incorporating a motor or a reduction gear train (for example, Patent Document 1).

  This walking toy has a movable body in which a flat back plate and a bottom plate are combined in a horizontal direction and a vertical direction so as to have an L-shape when viewed from the side, and a left and right side of the movable body. A plate-shaped swinging plate having a substantially fan shape outside the side plate, and the two plate-shaped swinging plates are arranged in parallel to the left and right sides of the movable body with the fan-shaped arc-shaped portion being downward. The swing plate is swingably attached near the upper end of the swing plate to near the front upper end of the side plate.

  A battery storage portion is formed on a back plate that is a vertical portion behind the movable body, and a permanent magnet is mounted in front of the battery storage portion. The side plates for attaching are extended forward from the back plate, respectively.The front end of the bottom plate resembles the forefoot, and a switch is provided at the front end of the bottom plate, and this switch contacts the mounting surface of the toy. This is a switch that is turned on.

  The swing plates arranged on both sides of the movable body have a connection plate connecting the front edges of the both swing plates, and an electromagnet is provided on the connection plate, and a switch provided at the front end of the bottom plate is turned on. When the electromagnet is energized, it repels the permanent magnet provided on the back plate, and moves the connecting plate forward, and thus the rocking plate forward.

  This rocking plate shall form a hind leg by projecting the lower end of the arc shape behind the forefoot portion of the front end of the bottom plate and lower than the bottom plate, and make the movable body in the air with the forefoot and the hindfoot almost at the same height. When held, the switch is turned off, the electromagnet and the permanent magnet are brought closer by the weight of the electromagnet and the connection plate, and the distance between the front foot formed at the front end of the bottom plate and the rear foot below the rocking plate is greatly separated, When the walking toy is placed on the table in this state, the center of gravity of the entire toy is located between the forefoot and the hindfoot.

  When the switch comes into contact with the walking surface and is turned on, power is supplied to the electromagnet integrated with the rocking plate whose upper end is swingably mounted near the front upper end of the side plate of the movable body. It repels the permanent magnet and moves forward, moves the lower part of the connecting plate and the swinging plate forward with respect to the movable body, and draws the lower end of the swinging plate, which is the rear foot, toward the front foot.

  In this way, when the lower end of the rocking plate as the rear foot moves forward and approaches the front foot, the toy walks on the front foot when the rear foot is forward from the center of gravity of the toy and the center of gravity is behind the rear foot. The switch is turned off and the power to the electromagnet is cut off.

  For this reason, the repulsive force between the electromagnet and the permanent magnet disappears, and the lower end is supported by the swinging plate having the rear foot, and the vicinity of the front upper end of the side plate is attached above the swinging plate, and the center of gravity is shifted from the rear foot position. The movable body, which is also rearward, swings so as to move the lower portion forward, so that the permanent magnet approaches the electromagnet.

  In this way, when the lower part of the movable body moves forward and the center of gravity of the toy is located ahead of the rear foot, the toy tilts forward around the contact position of the rear foot on the walking surface, Bring the forefoot into contact with the walking surface.

  When the forefoot touches the walking surface, the switch is turned on, the permanent magnet energizes the approaching electromagnet to generate a repulsive force, moves the electromagnet forward, and the hindfoot to the forefoot grounded on the walking surface. Is moved closer.

  In this way, when the rear foot is located forward of the center of gravity of the toy, the forefoot is lifted, the center of gravity of the movable body is moved downward, and the center of gravity of the forefoot and the movable body, and furthermore, the center of gravity of the toy is moved forward, and the forefoot is brought into contact with the walking surface. , And walk by pulling the hind legs.

  As described above, this toy has a movable body that supports a small battery such as a button battery and a permanent magnet, an electromagnet positioned in front of the permanent magnet, a connecting plate on which the electromagnet is mounted, and a movable body fixed to both ends of the connecting plate. An extremely small walking toy with a height and width of about 2 cm, which is composed of a rocking member formed of a rocking plate whose upper end is mounted near the front upper end of the side plate outside the side plate. Is what you can do.

  Then, as shown in FIG. 7, the wiring of this walking toy has a contact portion 223 at the lower end, which is in contact with the negative pole, which is the end surface of the battery 155 stored in the battery storage portion of the back plate, and an electromagnet at the upper end. The first conductive wire plate 220 to which the coil lead wire 183 is connected, and the rear end of which is in contact with the peripheral wall of the battery 155, which is the positive pole of the battery 155, and the front end is located above the switch movable body 210 provided near the forefoot position. A second conductor plate 230, a horizontal portion 253 above the switch movable body 210 to which a J-shaped elastic contact rod 255 located below the second conductor plate 230 is attached, and an upper end of a vertical portion 251 rising from the horizontal portion 253. And a third conductive plate 250 to which a coil lead wire 183 is connected.

  The switch movable body 210 is substantially U-shaped, has a recess on the upper surface, is inserted into a through hole provided in the center near the front end of the bottom plate, and has a lower end downward from the lower surface of the bottom plate without falling off from the through hole. Projecting, the vicinity of the front end of the elastic contact rod 255 positioned below the bottom plate or the front end of the second conductive wire plate 230 fixed to the upper surface of the bottom plate is housed in a recess formed in the upper surface, and the bottom plate is inserted into the through hole in the bottom plate. It can be moved up and down.

  When the electromagnet is not energized, for example, when the toy is placed on a walking surface such as a table with the battery 155 removed, when the lower surface of the switch movable body 210 contacts the walking surface, the switch movable body 210 is placed on the bottom plate. , The tip portion 257 of the resilient contact rod 255 fixed to the third conductor plate 250 is pushed up to bring the folded portion 259 into contact with the second conductor plate 230, and the power to the electromagnet is reduced. When the forefoot is lifted from the walking surface and the switch movable body 210 is separated from the walking surface, the switch movable body 210 is lowered by its own weight inside the through hole, and the third conductor plate 250 fixed to the lower surface of the bottom plate is set. The elastic contact rod 255 connected to and fixed to is returned to a normal state by the elastic force of the rod-shaped part 256, lowers the tip part 257, separates the folded part 259 from the second conductor plate 230, and changes the state of energization to the electromagnet. It is to cancel.

  As described above, this small walking toy is formed by forming the J-shaped elastic contact rod 255, which is a thin steel wire having elasticity, with a slight gap between the second conductive wire plate 230 and the second conductive wire plate 230. The elastic contact rod 255 arranged below the 230 and fixed to the third conductor plate 250 is such that when the tip 257 of the elastic contact rod 255 is lifted from below by the switch movable body 210, the rod-shaped portion 256 of the elastic contact rod 255 is curved. When the switch movable body 210 is lowered, the elastic contact rod 255 returns to the normal shape and the second conductive wire plate 230 Is released and the energization of the electromagnet and the interruption of the energization are repeated to cause the walking toy to walk.

  And this walking toy is a walking toy pursuing miniaturization of the whole toy without having a motor, a reduction gear and a power switch, and always walks with the forefoot and hindfoot placed on a flat surface. Therefore, when walking is not performed, it is stored upside down.

JP 2008-048879 A

  As described above, a small walking toy that does not have a power switch and is turned upside down during storage may be a product that consumes batteries in a short time during storage and does not perform walking when used. .

  This is because when the walking toy is stored upside down, the switch movable body pushes down the tip of the resilient contact rod due to the weight of the switch movable body, and the tip of the resilient contact rod comes into contact with the second conductor plate. This is to maintain the energized state of the electromagnet during storage and consume the battery, which is a phenomenon that occurs in a product in which the gap between the second conductive plate and the tip of the elastic contact rod is narrow.

  Products with a narrow gap between the second conductive wire plate and the tip of the elastic contact rod are subject to manufacturing errors of parts, external stress during storage and transfer of parts before assembly, and the like, and due to assembly errors of walking toys. When the walking toy is assembled, the distance between the second conductor plate and the tip of the elastic contact rod varies, and the gap between the second conductor plate and the tip of the elastic contact bar is produced as a narrow product. This is because a case may occur.

  In order to remove such a product from the finished product, it is necessary to adjust the gap. However, the gap between the second conductor plate and the tip of the elastic contact rod caused by a manufacturing error or an assembly error of the parts is not uniform. Adjusting the tip position of the elastic contact rod having elasticity to a predetermined gap by adjusting the position of the elastic contact rod requires a great deal of time and trouble, and has been a difficult task.

  Therefore, in order to solve such a problem, the present invention configures a switch without using an elastic member, and can prevent a careless ON state from being used. Is provided.

  The switch for a walking toy according to the present invention incorporates a battery, an electromagnet, and a permanent magnet, and causes the rear foot to approach the front end from the rear of the toy by the repulsive force of the permanent magnet and the electromagnet. In support of the toy, the front end is lifted from the walking surface, and when the front end is lifted, the switch is turned off to cut off the current to the electromagnet, and the repulsive force between the permanent magnet and the electromagnet is reduced. The front end, which is floated so as to widen the interval between the hind foot and the front end by allowing the permanent magnet and the electromagnet to approach each other by disappearing, is sent forward, and the center of gravity of the toy moves the toy. A walking toy that repeats bringing the front end into contact with the walking surface by turning the switch to the ON state by being forward of the supporting rear foot, and bringing the rear foot closer to the front end again. A swing contact plate to which one coil lead wire of the electromagnet is connected; a conductive wire plate to which a contact portion formed at a front end of the swing contact plate can be contacted from below; A switch movable body that pushes up the vicinity of the front end of the moving contact plate, wherein the switch movable body is vertically movably attached to the front end of the toy and the bottom of the switch movable body is lowered from the lower surface of the toy. The swing contact plate has a rectangular flat plate-shaped main body which is made of metal affected by magnetic force and is long in the front-rear direction, and a vertical portion which rises from the rear end of the main body. The front end of the permanent magnet is positioned below the conductive wire plate and placed on the bottom of the switch movable body, and further, the vertical portion is positioned near the lower part of the magnetic pole surface periphery of the permanent magnet to swing the middle of the main body. The main body as a driving shaft The front end and the rear end can be swung up and down, and the on / off state for performing a walking operation by using magnetic force without using an elastic body is repeated, and the switch is inadvertently turned on and off. It is something that does not become.

  In the walking toy switch, it is preferable that the swing contact plate is housed in a recess formed in a bottom plate of the toy, and the conductive wire plate is attached to an upper surface of the bottom plate of the toy.

  Further, the swing contact plate has a support arm portion extending left and right from a front-rear middle portion of the main body portion having a rectangular shape long in the front-rear direction, and is supported near both left and right ends of the support arm portion. Preferably, the main body is swingable.

  The switch for a walking toy according to the present invention, by swinging the main body of the swing contact plate so as to move the front end of the swing contact plate made of a metal affected by the magnetic force of a rectangular flat plate elongated in the front-back direction up and down. The switch is turned on and off, and the swing contact plate for turning on and off the contact is a flat metal plate. Therefore, the swing contact plate is inadvertently deformed during storage or transfer before assembly. In addition, the manufacturing error of the component hardly occurs, and the interval between the contact portion of the swing contact plate and the conductive wire plate with which the contact portion comes into contact can be easily maintained within a predetermined range.

  In addition, the front end of the main body of the swing contact plate is placed on the bottom of the switch movable body, and the vertical portion is located near the lower part of the peripheral surface of the magnetic pole surface of the permanent magnet. Since the front and rear ends can be swung up and down, the rear end of the swing contact plate is attracted by a permanent magnet to position the front end downward, and when the switch movable body is pushed up, the front end moves upward. The switch is turned on by making contact with the conductive wire plate, and the force required to push up the front end by the switch movable body for turning on the switch is applied to the vertical portion of the swing contact plate and the permanent magnet. The distance can be adjusted so that the switch is not accidentally turned on when the walking toy is turned upside down.

  If the conductor plate is mounted on the upper surface of the bottom plate and the swing contact plate is housed in a recess formed in the bottom plate, the contacts of the swing contact plate are set at a predetermined interval below the conductor plate. Can be easily assembled.

  Furthermore, by forming a support arm extending left and right from the front-rear direction intermediate portion of the main body of the swing contact plate, not only the main body is curved, but also the swing arm is bent. The gap between the contact portion of the plate and the conductive wire plate and the distance between the vertical portion of the swing contact plate and the permanent magnet can be easily adjusted.

Is caused.

  When the switch movable body 210 is pushed up from below by an external force, the switch movable body 210 swings around the contact plate pressing portion 135 so as to slightly increase the distance between the upper end 244 of the vertical portion 243 and the end of the magnetic pole surface of the permanent magnet 151. Then, the contact portion 245 is brought into contact with the switch contact point portion 237 to enable conduction between the second conductor plate 230 and the swing contact plate 240.

  The external force that causes the contact portion 245 to come into contact with the switch contact point portion 237 is a force that is greater than the own weight of the switch movable body 210 and smaller than about a fraction to one-tenth of the total weight of the walking toy 100. The distance between the upper end 244 of the vertical portion 243 and the end of the pole face of the permanent magnet 151 is determined, and the front end of the oscillating contact plate 240 is the number of the total weight of the walking toy 100. The force for attracting the vertical portion 243 by the permanent magnet 151 is determined so that the switch movable body 210 can push up the vertical portion 243 with a force smaller than one-half.

  Therefore, in a state where the forefoot part 149 and the hindfoot part 168 of the walking toy 100 are up and the ear 112 and the back are in contact with a flat surface, the vertical part 243 is attracted by the permanent magnet 151 and the contact part 245 is brought into switch contact. The switch 200 can be turned off by separating from the dot portion 237.

  Also, when the walking toy 100 is lifted substantially horizontally with the forefoot part 149 and the hindfoot part 168 downward, the switch 200 remains off and the electromagnet 180 approaches the permanent magnet 151 without energizing the electromagnet 180. The rear toe portion 168 can be separated from the forefoot portion 149, and when the walking toy 100 is placed substantially horizontally on the walking surface 191 as shown in FIG. The lower end 215 of 210 can contact the walking surface 191.

  Therefore, the weight of the walking toy 100 is added to the switch movable body 210 provided near the front end of the bottom plate 141 which is the position of the forefoot portion 149, the switch 200 is turned on, and the electromagnet 180 is energized, and the electromagnet 180 is permanently energized. A repulsive force with the magnet 151 is generated.

  For this reason, the electromagnet 180 is pushed forward, and the hind foot 168 approaches the fore foot 149 formed at the front end of the walking toy 100, and the contact point of the hind foot 168 with the walking surface 191 is the entire toy. 6B, the front end of the walking toy 100 is lifted so as to separate the forefoot 149 from the walking surface 191 as shown in FIG. 6B.

  For this reason, the switch 200 is turned off, the repulsive force of the electromagnet 180 against the permanent magnet 151 disappears, and the movable body 120 supported on the swing plate 161 by the swing pin 133 becomes the movable body 120 and the outer case 110. Is located behind the line connecting the contact point of the hind foot 168 with the walking surface 191 and the swing pin 133, so that the swing center of the swing pin 133 moves downward and forward. When the center of gravity of the entire toy such as the movable body 120 is located ahead of the contact point, the walking toy 100 is tilted forward to contact the switch movable body 210 with the walking surface 191 as shown in FIG. The switch 200 is turned on.

  In this manner, the walking toy 100 moves forward so as to walk by repeatedly turning the switch 200 on and off, similarly to the conventional walking toy 100.

  In the walking toy 100, the swing contact plate 240 and the second conductor plate 230 constituting the switch 200 are made of a metal plate such as stainless steel, and the second conductor plate 230 is fixed to the upper surface of the bottom plate 141. The swing contact plate 240 in which the contact portion 245 is located below the switch contact point portion 237 of the second conductor plate 230 can swing around the position of the contact plate pressing portion 135 and the auxiliary support protrusion 147 so as to be housed in the contact plate main body. The contact portion 245 is slightly separated from the switch contact point portion 237 by being housed in the contact portion 145 and the contact plate arm storage portion 146 and attracting and lifting the rear end of the swing contact plate 240 by the permanent magnet 151. The switch 200 can be reliably turned on and off.

  Further, since the swing contact plate 240 is a metal plate made of stainless steel or the like as the rectangular flat plate-shaped main body portion 241, the shape holding property is high, the variation for each product is unlikely to occur, and the contact portion 245 and the switch contact point portion This makes it easy to manufacture a product with a constant distance from the 237.

  Furthermore, variations occur due to manufacturing errors and assembly errors, and the contact portion 245 and the switch contact point portion 237 are likely to come into contact with each other. Even if the walking toy 100 is assembled into a product that can be assembled, the distance between the upper end 244 of the vertical portion 243 of the swing contact plate 240 and the permanent magnet 151 is adjusted to make the rear end of the swing contact plate 240 a magnet. It is possible to easily increase the attraction force so that the contact between the contact portion 245 and the switch contact point portion 237 hardly occurs.

  That is, the distance between the permanent magnet 151 and the rear end of the swing contact plate 240 is reduced by slightly moving the permanent magnet 151 downward, or the front and rear ends of the main body 241 of the swing contact plate 240 are pushed upward. The upper end 244 of the vertical portion 243 approaches the permanent magnet 151 in a state where the front end of the main body 241 is in contact with the upper surface of the main body 211 of the switch movable body 210. The entire supporting arm 247 is curved so that the tip of the supporting arm 247 of the moving contact plate 240 is directed downward, so that the position of the supporting arm 247 of the main body 241 is raised, and the front end of the main body 241 is switched to the switch movable body 210. The upper end 244 of the vertical portion 243 is brought close to the permanent magnet 151 while being in contact with the upper surface of the main body 211, and the vertical portion 243 of the swing contact plate 240 is brought close to the permanent magnet 151 by pulling up the rear end of the swing contact plate 240. It can increase the power.

  When bending the main body portion 241 of the swing contact plate 240 or bending the support arm portion 247, setting the long axis direction of a metal plate such as a plate-shaped rectangular stainless steel to a predetermined curved state is an elasticity. It is possible to adjust the bending state to a predetermined bending state very easily and in a short time as compared with the bending adjustment of a steel wire having a contact point 245 of the oscillating contact plate 240 and a switch contact point of the second conductor plate 230. This facilitates adjustment of the force required to make the contact with the portion 237.

  In addition, the position at which the permanent magnet 151 is fixed to the back plate 121 can be easily adjusted by changing the position in a very short time, so that the upper end of the vertical portion between the permanent magnet 151 and the swing contact plate 240 can be adjusted. It is easy to adjust the force required to adjust the distance to the contact 245 of the oscillating contact plate 240 and the switch contact point 237 of the second conductor plate 230 by adjusting the distance to the switch contact point 244. This makes it possible to easily prevent the occurrence of defective products that cause the exhaustion of the battery 155.

  The switch for a walking toy according to the present invention is a switch 200 that makes it easy to assemble the walking toy 100 with the contact interval of the switch within a predetermined range, and a pressing force required to turn on the switch 200. This is a walking toy switch that can be easily adjusted, and can be used as the walking toy 100 without the switch 200 being unnecessarily turned on to waste battery power.
