Description

本発明は、四足歩行などの動物の形状を模した歩行玩具に関するものである。   The present invention relates to a walking toy imitating the shape of an animal such as a quadrupedal walking.

今日、犬や馬などの四足動物の玩具が種々提供されている。
そして、これら四足歩行の動物玩具では、前足及び後足を前後に動作させることにより、自然な歩行動作を見せるようにしているものがある。
Today, various quadruped toys such as dogs and horses are provided.
Some of these four-legged animal toys are designed to show a natural walking motion by moving the front and rear legs back and forth.

しかし、前足及び後足を前後動作させる歩行形態では、左右への方向変換を含む歩行動作を行わせるには機構及び制御が複雑となるため、四足歩行玩具では、前足を取り付ける前胴部と後足を取り付ける後胴部とによる胴部構造とし、後胴部に対して前胴部を左右に揺動可能とし、前胴部ひいては前足の前後移動方向を変更させて歩行方向を変化させるようにするものが提案(例えば特許文献1)されている。   However, in the walking mode in which the front and rear legs are moved back and forth, the mechanism and the control are complicated in order to perform the walking movement including the direction change to the left and right. A torso structure with a rear torso to which the rear foot is attached, the front torso can be swung to the left and right with respect to the rear torso, and the walking direction is changed by changing the front torso and thus the front and rear movement direction of the front foot. There is a proposal (for example, Patent Document 1).

また、左右の後足の下端に車輪を設け、後足を前方に移動させるときは車輪の回転を自在とし、後足を後方に移動させるときは車輪の回転を固定して胴部の前進を確保して直進前進を行わせ、左右何れか一方の後ろ足の車輪を常に固定状態とし、後足を前方に移動させるとき、固定された車輪を有する右側又は左側の前進動作に制動を加えることにより、方向変換を行わせるようにするものも提案(例えば特許文献2)   In addition, wheels are provided at the lower ends of the left and right hind legs so that the wheels can rotate freely when moving the hind legs forward, and when moving the hind legs backward, the rotation of the wheels is fixed and the torso is advanced. By making sure that the left and right rear foot wheels are always fixed and moving the rear foot forward, braking is applied to the right or left forward movement with the fixed wheels. Also proposed to change the direction (for example, Patent Document 2)

特開2004―073306号公報JP 2004-073306 A 特開2003―320175号公報Japanese Patent Laid-Open No. 2003-320175

前述の様に、前足及び後足を前後動作させて歩行や走行を行わせる四足歩行玩具は、四本の足を固定足として各足の下端に駆動輪と回転自由な車輪を設けて前進させる歩行玩具に比較して、足を前後させることにより自然な状態の歩行または走行動作を行わせて遊戯者を楽しませることができるも、方向変換を行う際、後胴に対して前胴の向きが変わる、又は足が前後しているのに床に対して足が滑る、などの不自然な動作が生じ、自然な方向変換動作を行わせることが困難であった。   As mentioned above, a quadruped walking toy that walks and runs with its front and rear legs moving back and forth moves forward with four legs as fixed legs and drive wheels and freely rotatable wheels at the bottom of each leg. Compared to a walking toy, it is possible to entertain a player by performing a natural walking or running motion by moving the foot back and forth, but when changing direction, the front torso An unnatural motion such as a change of direction or a foot slipping with respect to the floor even when the foot is moving back and forth has occurred, making it difficult to perform a natural direction changing operation.

本発明は、このような欠点を排除し、比較的単純な構造や操作により自然な直進動作及び方向変換動作を行わせることのできる歩行玩具を提供するものである。   The present invention eliminates such drawbacks and provides a walking toy that can perform natural straight-ahead movement and direction changing movement with a relatively simple structure and operation.

本発明に係る歩行玩具は、左右の前足及び左右の後足とする4本の作動足を有し、左前足の作動を左後足に伝達して前記左後足を作動させるリンクバーと右前足の作動を右後足に伝達して前記右後足を作動させるリンクバーとを有し、前記リンクバーにより前記前足の下端が前方に作動するときに前記後足の下端を後方に作動させ、前記左右の後足は固定揺動軸を中心にその下端を前後に揺動させるものとし、前記左右の前足は伝達回転軸から偏心した偏心軸の回転移動により円運動の作動を行い、前記左前足の前記偏心軸と前記右前足の前記偏心軸は伝達回転軸の回転方向に180度ずれて前記左前足と前記右前足の円運動を半周期異ならせ、前記左右の前足は前記偏心軸の位置よりも上方に縦長の揺動軸穴を有し、前記揺動軸穴に挿入されて上下に移動可能とされる可動揺動軸により前記左右の前足は前後方向の移動が規制されて前記左前足及び前記右前足の下端に円運動を行わせることを特徴とする。   The walking toy according to the present invention has four actuating legs, which are left and right forefoot and left and right hind legs. The link bar and the right front which actuate the left hind leg by transmitting the action of the left forefoot to the left hind leg. A link bar that transmits the action of the foot to the right hind leg to actuate the right hind leg, and when the lower end of the front leg is actuated forward by the link bar, the lower end of the hind leg is actuated backward. The left and right hind legs are rocked back and forth around a fixed rocking shaft, and the left and right front legs perform a circular motion by rotational movement of an eccentric shaft eccentric from the transmission rotation shaft, The eccentric shaft of the left forefoot and the eccentric shaft of the right forefoot are shifted by 180 degrees in the rotational direction of the transmission rotation shaft to make the circular motion of the left forefoot and the right forefoot different from each other by a half cycle. Has a vertically long rocking shaft hole above the position, and inserted into the rocking shaft hole. The right and left front foot by variable rocking shaft which is vertically movable Te is characterized in that to perform circular motion in the lower end of the left front foot and the right forefoot is restricted movement in the longitudinal direction.

また、この歩行玩具は、前記左前足の前記揺動軸穴に挿入される前記可動揺動軸と前記右前足の前記揺動軸穴に挿入される前記可動揺動軸は一本の可動揺動軸とされ、この一本の可動揺動軸の中央を中心に回転可能とされて前記左前足への挿入部分を上昇させるときには前記右前足への挿入部分を降下させ、前記左前足への前記挿入部分を降下せるときには前記右前足への前記挿入部分を上昇させるようにすることもある。   In this walking toy, the movable swing shaft inserted into the swing shaft hole of the left forefoot and the movable swing shaft inserted into the swing shaft hole of the right forefoot are one movable swing shaft. When moving up the insertion part to the left forefoot, the insertion part to the right forefoot is lowered and moved to the left forefoot. When the insertion portion is lowered, the insertion portion to the right forefoot may be raised.

更に、前記揺動軸穴は、下方よりも上方の前後幅を広くすることが好ましい。   Furthermore, it is preferable that the rocking shaft hole has a wider front and rear width than the lower side.

そして、前記リンクバーは、前記偏心軸よりも下方で前記左右の前足に前端が各々接続され、前記固定揺動軸よりも上方で前記左右の後足に後端が各々接続されるものである。   The link bar has a front end connected to the left and right front legs below the eccentric shaft, and a rear end connected to the left and right rear legs above the fixed swing shaft. .

また、前記作動足とする前記前足と前記後足との間、又は前記前足の前方や前記後足の後方に、足形状を模した装飾足を備えることもある。   In addition, a decorative foot imitating a foot shape may be provided between the front foot and the rear foot as the working foot, or in front of the front foot or behind the rear foot.

本発明は、上述の様に、左右の前足及び左右の後足とされる4本の作動足を有し、リンクバーにより前足が前方に移動させるときに後足を後方に揺動させ、前足は左右で180度ずらせて円運動をさせるため、左前足を下げて後方に移動させるとき右前足を上げて前方に移動させ、左前足を上げて前方に移動させるとき右前足を下げて後方に移動させ、自然な歩行動作または足の動きを早くして走行動作を行わせることができる。   As described above, the present invention has four operating feet which are left and right forefoot and left and right rear foot, and when the front foot is moved forward by the link bar, the rear foot is swung backward, Is moved 180 degrees left and right to move the circle, so when lowering the left forefoot and moving backward, the right forefoot is raised and moved forward, and when moving the left forefoot and moved forward, the right forefoot is lowered and moved backward It is possible to move and perform a walking motion with a natural walking motion or fast foot movement.

そして、左右の前足は、前足に円運動を行わせる偏心軸の位置よりも上方に縦長の揺動軸穴を有すると共に、揺動軸穴に挿入されて上下移動可能とされる可動揺動軸を有し、可動揺動軸により前足の円運動に際する前後移動を規制しており、可動揺動軸を上下移動させることにより偏心軸との距離を変化させることができるため、偏心軸と可動揺動軸の距離を変化させて前足下端の前後移動幅、即ち歩行に際しての歩幅を変化させることが可能となり、左右の歩幅に差を生じさせて自然な方向変換を行うことを可能とした歩行玩具とすることができるものである。   The left and right forefoot have a vertically long rocking shaft hole above the position of the eccentric shaft that causes the forefoot to make a circular motion, and is a movable rocking shaft that is inserted into the rocking shaft hole and can move up and down. The front and rear movements of the forefoot in a circular motion are regulated by the movable swing shaft, and the distance from the eccentric shaft can be changed by moving the movable swing shaft up and down. By changing the distance of the movable swing shaft, it is possible to change the front / rear movement width of the lower end of the front foot, that is, the step length during walking, and it is possible to make a natural direction change by causing a difference between the left and right step lengths. It can be used as a walking toy.

また、左右の可動揺動軸を一本の可動揺動軸としてこの一本の可動揺動軸の中央を中心に回転可能とすれば、左右の前足への挿入部分を逆方向に移動させて左前足への挿入部分を上昇させるときに右前足への挿入部分を降下させ且つ左前足への前記挿入部分を降下せるときに右前足への前記挿入部分を上昇させることが容易に可能となり、左前足の下端を小さく前後移動させるとき右前足下端の前後移動を大きく、左前足の下端を大きく前後移動させるとき右前足下端の前後移動を小さくし、方向変換を容易に行うことができる。   In addition, if the left and right movable swing shafts are used as a single movable swing shaft and the center of the single movable swing shaft can be rotated, the insertion part to the left and right forefoot can be moved in the opposite direction. It is possible to easily lower the insertion part to the right forefoot when raising the insertion part to the left forefoot and raise the insertion part to the right forefoot when lowering the insertion part to the left forefoot, When the lower end of the left forefoot is moved back and forth small, the forward and backward movement of the lower end of the right forefoot is increased, and when the lower end of the left forefoot is moved back and forth greatly, the back and forth movement of the lower end of the right forefoot is reduced.

そして、揺動軸穴は上方の前後幅を下方よりも広くすれば、前足の歩幅を小さくするとき、後足の移動に合わせて左右の歩幅の差による無理な力が前足に加わることを防止し、無理なく歩幅変更を行って円滑かつ確実な方向変換を行わせることができる。   If the front and rear width of the swinging shaft hole is wider than the lower side, when the front leg stride is reduced, it is possible to prevent excessive force from being applied to the front leg due to the difference between the left and right stride as the rear leg moves. In addition, it is possible to change the stride without difficulty and perform smooth and reliable direction change.

さらに、リンクバーにより前足の偏心軸よりも下方と後足の固定揺動軸の上方とを接続すれば、前足と後足との前後移動を逆方向とすることが容易に可能となる。   Furthermore, if the link bar connects the lower part of the front foot eccentric shaft and the upper part of the fixed swing shaft of the rear foot, the front and rear movements of the front foot and the rear foot can be easily reversed.

また、前足と後足との間や前足の前方、後足の後方に装飾足を設ければ、四足歩行動物に限ることなく、多足動物などの歩行玩具とし、作動足の動きを早くして多足動物の走行動作をする歩行玩具とすることもできる。   In addition, if a decorative foot is provided between the front foot and the rear foot, in front of the front foot, and behind the rear foot, it is not limited to a quadruped walking animal, and it can be used as a walking toy such as a multi-legged animal. And it can also be set as the walking toy which carries out the movement operation | movement of a multilegged animal.

この歩幅変換具261は、T字形状の本体部263の中央から前方に突出させる揺動回転軸265を本体前板141に貫通させて本体前板141の後方に配置する本体部263を揺動回転軸265を回転中心軸として回転可能とし、この本体部263から棒状の左前足揺動軸267及び右前足揺動軸268を夫々左右に突出させるように有するものである。   The stride conversion tool 261 swings the main body 263 disposed behind the main body front plate 141 by passing through the main body front plate 141 a swing rotation shaft 265 that protrudes forward from the center of the T-shaped main body 263. The rotary shaft 265 is rotatable about a rotation center axis, and a rod-like left forefoot rocking shaft 267 and right forefoot rocking shaft 268 are protruded from the main body 263 to the left and right, respectively.

そして、揺動回転軸265は、本体前板141の略中央にして左前足161及び右前足171の中央に配置され、左前足揺動軸267の先端を左前足161の揺動軸穴165に挿入貫通させ、右前足揺動軸268の先端を右前足171の揺動軸穴175に挿入貫通させるものであって、本体部263から左右に突出した左前足揺動軸267及び右前足揺動軸268を水平としたとき、左前足揺動軸267及び右前足揺動軸268は、左前足161及び右前足171に各々縦長に形成された揺動軸穴165、175の略中央高さに位置して夫々先端を左前足161及び右前足171から外側に突出させるものである。   The swing rotation shaft 265 is disposed at the center of the left front foot 161 and the right front foot 171 so as to be approximately in the center of the main body front plate 141, and the tip of the left front foot swing shaft 267 is inserted into the swing shaft hole 165 of the left front foot 161. Inserts and penetrates the tip of the right forefoot swing shaft 268 into the swing shaft hole 175 of the right forefoot 171. The left forefoot swing shaft 267 protruding right and left from the main body 263 and the right forefoot swing When the shaft 268 is horizontal, the left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 are approximately at the center height of the rocking shaft holes 165 and 175 formed vertically in the left forefoot 161 and the right forefoot 171, respectively. It is located and the front-end | tip protrudes outside from the left front leg 161 and the right front leg 171, respectively.

また、基台本体113の後方端部近傍にはモータ押え153の位置よりも僅かに上方まで伸びる高さの支柱117を有し、本体前板141の上端近傍とこの支柱117の上端により上カバー板151を固定して歩幅変換具261や駆動モータ210の上方を覆い、この上カバー板151には赤外線受信器などの受信器157と、制御基板155と、電源スイッチ156を設けるものである。   Further, in the vicinity of the rear end portion of the base main body 113, there is a support column 117 having a height extending slightly above the position of the motor presser 153, and the upper cover is formed by the vicinity of the upper end of the main body front plate 141 and the upper end of the support column 117. The plate 151 is fixed and covers the step converter 261 and the drive motor 210. The upper cover plate 151 is provided with a receiver 157 such as an infrared receiver, a control board 155, and a power switch 156.

この電源スイッチ156は、基台本体113に収納した電池により当該歩行玩具100を動作可能状態とするものであり、制御基板155は、図示しない送信機からの信号を受信器157で受信することにより、駆動モータ210の正逆回転及び停止と、揺動モータ250の正逆回転及び停止を制御する制御手段としての回路が設けられるものである。   This power switch 156 makes the walking toy 100 operable by a battery stored in the base body 113, and the control board 155 receives a signal from a transmitter (not shown) by a receiver 157. A circuit is provided as a control means for controlling forward / reverse rotation and stop of the drive motor 210 and forward / reverse rotation and stop of the swing motor 250.

従って、歩幅変換具261の左前足揺動軸267及び右前足揺動軸268を水平状態として駆動モータ210を正回転させると、図4及び図5に示すように、偏心用歯車235が半時計方向に回転し、図4(a)に示すように偏心用歯車235の左偏心軸237即ち左前足161の駆動穴163を偏心用歯車235の後方位置から図4(b)に示す偏心用歯車235の上方位置に、更に図5(a)に示す偏心用歯車235の前方位置とした後、図5(b)に示す偏心用歯車235の下方位置を介して図4(a)に示した後方位置に戻すように、駆動穴163ひいては左前足161に円運動をさせるように回転動作を行わせることができる。   Therefore, when the drive motor 210 is rotated forward with the left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 of the stride conversion tool 261 in a horizontal state, the eccentric gear 235 is rotated half-clockwise as shown in FIGS. 4 (a), the left eccentric shaft 237 of the eccentric gear 235, that is, the drive hole 163 of the left front foot 161 is moved from the rear position of the eccentric gear 235 to the eccentric gear shown in FIG. 4 (b). 4A, after the position of the eccentric gear 235 shown in FIG. 5A is set to the front position of the eccentric gear 235 shown in FIG. 5B, the position shown in FIG. In order to return to the rear position, the drive hole 163 and thus the left forefoot 161 can be rotated so as to make a circular motion.

そして、揺動軸穴165は、上下方向に長穴とされると共に図面に示したように略下半部分は左前足揺動軸267の直径に近い前後幅とされ、上半部分は前後幅が上方に向かって順次徐々に広く形成しているも、この揺動軸穴165に挿入される左前足揺動軸267により左前足161の前後動作が規制され、偏心用歯車235の左偏心軸237及び左前足161の駆動穴163が後方から上方を介して前方に移動するとき、この駆動穴163によりも上方に配置された揺動軸穴165により左前足161の前後動作が規制され、左前足161の下端を大きく前方に移動させる。   The swinging shaft hole 165 is an elongated hole in the vertical direction, and as shown in the drawing, the substantially lower half portion has a front-rear width close to the diameter of the left forefoot swinging shaft 267, and the upper half portion has a front-rear width. Are gradually formed wider toward the upper side, but the front and rear movements of the left front foot 161 are restricted by the left front foot swing shaft 267 inserted into the swing shaft hole 165, and the left eccentric shaft of the eccentric gear 235 is When the drive hole 163 of the 237 and the left forefoot 161 moves forward from behind through the upper side, the front and rear movements of the left forefoot 161 are restricted by the swinging shaft hole 165 disposed above the drive hole 163, and the left front The lower end of the foot 161 is moved largely forward.

更に、偏心用歯車235の左偏心軸237及び左前足161の駆動穴163を前方から下方を介して後方に回転移動させるとき、図5(a)、図5(b)、図4(a)に示したように、左前足161の下端を一旦降下させた後に上昇させるようにしつつ、左前足161の上方の前後動作が規制されて左前足161の下端を前方から後方に移動させることができる。   Further, when the left eccentric shaft 237 of the eccentric gear 235 and the drive hole 163 of the left forefoot 161 are rotated and moved rearward from the front through the lower part, FIG. 5 (a), FIG. 5 (b), FIG. As shown in FIG. 4, the lower front end of the left forefoot 161 can be moved from the front to the rear by restricting the front and rear movements of the left front foot 161 while the lower end of the left forefoot 161 is lowered and then raised. .

このとき、右前足171は、偏心用歯車235の左偏心軸237と180度回転位相をずらせた右編軸により、左前足161と同様にその下端を前後動作させると共に、図4(a)に示したように、左前足161の下端が後方のとき、右前足171の下端を左前足161の下端と同一高さの前方位置とし、図4(b)に示したように、左前足161の下端が上方のときは右前足171の下端を下方とし、図5(a)に示したように、左前足161の下端が前方のとき、右前足171の下端を左前足161の下端と同一高さの後方とし、図5(b)に示したように、下端が下方のときは右前足171の下端を上方とするように移動させる。   At this time, the right forefoot 171 is moved back and forth in the same manner as the left forefoot 161 by the right knitting shaft that is 180 degrees out of phase with the left eccentric shaft 237 of the eccentric gear 235, and also shown in FIG. As shown in FIG. 4B, when the lower end of the left forefoot 161 is rearward, the lower end of the right forefoot 171 is set to the front position at the same height as the lower end of the left forefoot 161. When the lower end is upward, the lower end of the right forefoot 171 is set to the lower side. As shown in FIG. 5A, when the lower end of the left forefoot 161 is forward, the lower end of the right forefoot 171 is flush with the lower end of the left forefoot 161. As shown in FIG. 5B, when the lower end is downward, the lower end of the right front foot 171 is moved upward.

そして、左前足161を左後足181に連結リンクバー201で接続し、連結リンクバー201は左前足161の駆動穴163よりも下方の前リンクピン167により前端を左前足161に、左後足181の軸穴183よりも上方の後リンクピン185により後端を左後足181に接続しており、左後足181の軸穴183は基台本体113の左後足軸127に回転可能に支持されているため、左前足161の方が前方のとき、左後足181の下端を後方とし、左前足161の方が後方のとき、左後足181の下端を前方とするように左後足軸127を固定揺動軸として、この左後足軸127を中心に左後足181の下端を揺動させる。   The left forefoot 161 is connected to the left hind foot 181 by a connecting link bar 201. The connecting link bar 201 has a front link pin 167 below the drive hole 163 of the left forefoot 161 and a front end at the left forefoot 161. The rear link pin 185 above the shaft hole 183 of the 181 connects the rear end to the left rear foot 181 so that the shaft hole 183 of the left rear foot 181 can rotate to the left rear foot shaft 127 of the base body 113 When the left forefoot 161 is forward, the lower left of the left rear foot 181 is the rear, and when the left forefoot 161 is rearward, the lower left of the left rear foot 181 is the front. Using the foot shaft 127 as a fixed swing shaft, the lower end of the left rear foot 181 is swung around the left rear foot shaft 127.

尚、右後足191も、連結リンクバー201により、右前足171に接続されているため、同様に、右前足171の下端が前方のとき右後足191の下端を後方とし、右前足171の下端が後方のとき右後足191の下端を前方とするように右後足軸129を固定揺動軸として、この右後足軸129を中心に揺動する。   Since the right rear foot 191 is also connected to the right front foot 171 by the connecting link bar 201, similarly, when the lower end of the right front foot 171 is the front, the lower end of the right rear foot 191 is the rear and the right front foot 171 When the lower end is rearward, the right rear foot shaft 129 is pivoted about the right rear foot shaft 129 with the right rear foot shaft 129 as a fixed swing shaft so that the lower end of the right rear foot 191 is forward.

このように、駆動モータ210を正回転させたとき、左前足161の下端が前方から後方に移動するとき、左偏心軸237及び駆動穴163が偏心用歯車235の回転中心となる伝達回転軸239の位置よりも下方を通り、左前足161の下端が右前足171の下端よりも低い位置となり、左前足161と右後足191により歩行玩具100を支え、左前足161の下端と右後足191の下端の後方移動により玩具を前進させる。   Thus, when the drive motor 210 is rotated forward, when the lower end of the left front foot 161 moves from the front to the rear, the left eccentric shaft 237 and the drive hole 163 serve as the rotation center of the eccentric gear 235, and the transmission rotation shaft 239 The lower end of the left forefoot 161 is lower than the lower end of the right forefoot 171 and the walking toy 100 is supported by the left forefoot 161 and the right rear foot 191. The lower end of the left forefoot 161 and the right rear foot 191 The toy is advanced by the rearward movement of the lower end of the toy.

そして、左前足161の下端が後方から前方に移動するとき、右前足171の下端が前方から後方に移動し、このとき、右前足171の下端は左前足161の下端よりも下方の位置となって前方から後方に移動するため、右前足171と左後足181により当該玩具を支え、当該玩具を前進させることになる。   When the lower end of the left forefoot 161 moves from the rear to the front, the lower end of the right forefoot 171 moves from the front to the rear. At this time, the lower end of the right forefoot 171 is positioned below the lower end of the left forefoot 161. Therefore, the toy is supported by the right forefoot 171 and the left hind foot 181 to advance the toy.

また、左前足161、左後足181、及び、連結リンクバー201による連結機構は、右前足171、右後足191、及び、連結リンクバー201による連結機構と同一構成として対称形状としているため、当該歩行玩具100に直進歩行を行わせることができる。   In addition, since the connection mechanism by the left forefoot 161, the left rear foot 181 and the connection link bar 201 has the same configuration as the connection mechanism by the right front foot 171, the right rear foot 191 and the connection link bar 201, it has a symmetrical shape. The walking toy 100 can be made to go straight ahead.

更に、当該歩行玩具100は、図2に示したように、本体前板141の前方に揺動モータ250及び揺動減速歯車列255を有し、歩幅変換具261の揺動回転軸265を回転可能としており、揺動モータ250を正回転又は逆回転させることにより揺動回転軸265を回転させ、図6に示すように、左前足揺動軸267の先端を下方のA位置とすると共に、右前足揺動軸268の先端を上方とし、又は、左前足揺動軸267の先端を上方のB位置とすると共に、右前足揺動軸268の先端を下方位置とすることができる。   Further, as shown in FIG. 2, the walking toy 100 has a swing motor 250 and a swing reduction gear train 255 in front of the main body front plate 141, and rotates the swing rotation shaft 265 of the stride conversion tool 261. The swinging rotation shaft 265 is rotated by rotating the swinging motor 250 forward or backward, and the tip of the left forefoot swinging shaft 267 is set to the lower A position as shown in FIG. The tip of the right forefoot swing shaft 268 can be set to the upper position, or the tip of the left forefoot swing shaft 267 can be set to the upper B position, and the tip of the right forefoot swing shaft 268 can be set to the lower position.

従って、図7及び図8に示すように、左前足揺動軸267の先端を揺動軸穴165の内部で下方に位置させると、図4及び図5に示した左前足揺動軸267及び右前足揺動軸268を水平とした状態よりも左前足揺動軸267が下方に位置して偏心用歯車235に近接した位置とすることができる。   Accordingly, as shown in FIGS. 7 and 8, when the front end of the left forefoot rocking shaft 267 is positioned downward in the rocking shaft hole 165, the left forefoot rocking shaft 267 shown in FIGS. The left forefoot rocking shaft 267 can be positioned lower than the state in which the right forefoot rocking shaft 268 is horizontal, and can be positioned close to the eccentric gear 235.

このため、偏心用歯車235の左偏心軸237及び左前足161の駆動穴163が図4及び図5と同じ回転運動を行っても、左前足161の前後移動は、駆動穴163の近くで前後移動が規制され、左前足161の下端の前後移動幅が大きくなる。   For this reason, even if the left eccentric shaft 237 of the eccentric gear 235 and the drive hole 163 of the left front foot 161 perform the same rotational movement as in FIGS. The movement is restricted, and the forward / backward movement width of the lower end of the left front foot 161 is increased.

そして、左前足揺動軸267の先端を上方に移動させると、図9及び図10に示したように、左前足161の前後移動を規制する左前足揺動軸267の先端が上方に移動して偏心用歯車235ひいては左偏心軸237の位置から遠くなり、揺動軸穴165の前後移動が規制される位置が左偏心位置から遠く、左前足161の下端の前後移動が小さくなる。   When the tip of the left forefoot swing shaft 267 is moved upward, as shown in FIGS. 9 and 10, the tip of the left forefoot swing shaft 267 for restricting the front and rear movement of the left forefoot 161 is moved upward. Thus, the position of the eccentric gear 235 and the left eccentric shaft 237 is farther, the position where the back and forth movement of the swing shaft hole 165 is restricted is far from the left eccentric position, and the front and rear movement of the lower end of the left forefoot 161 is reduced.

即ち、左前足揺動軸267及び右前足揺動軸268は、左前足161の揺動軸穴165や右前足171の揺動軸穴175への挿入部分を上下移動可能とされ、左前足161や右前足171の円運動に際しての前後移動を左前足161や右前足171の上方で規制し、左前足161や右前足171の下端の前後移動量を変更規制するように左前足161や右前足171の揺動幅を変更させる上下移動可能な可動揺動軸としているものである。   That is, the left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 can move up and down in the portions inserted into the rocking shaft hole 165 of the left forefoot 161 and the rocking shaft hole 175 of the right forefoot 171. The left and right forefoot 161 and right forefoot 171 are restricted to move forward and backward during the circular movement of the right forefoot 171 and above the left forefoot 161 and right forefoot 171 and change the amount of forward and backward movement for the lower end of the left forefoot 161 and right forefoot 171. This is a movable rocking shaft that can move up and down to change the rocking width of 171.

尚、図7及び図8に示したように、左前足161の下端が大きく前後に移動するとき、左後足181の下端も大きく前後に移動し、図9及び図10に示したように、左前足161の下端の前後移動が小さくなるとき、左後足181の下端の前後移動も小さくなり、同様に右前足171の下端が大きく前後移動するとき、右後足191の下端の前後移動も大きく、右前足171の下端の前後移動が小さいとき、右後足191の下端の前後移動も小さくなる。   As shown in FIGS. 7 and 8, when the lower end of the left front foot 161 moves largely back and forth, the lower end of the left rear foot 181 also moves back and forth greatly, as shown in FIGS. When the lower front / rear movement of the lower left forefoot 161 is reduced, the lower front / rear movement of the lower left foot 181 is also reduced. When it is large and the back-and-forth movement of the lower end of the right forefoot 171 is small, the back-and-forth movement of the bottom of the right hind leg 191 is also reduced.

そして、図6に示したように、歩幅変換具261を回転させて左前足揺動軸267の先端を下方のA位置に位置させたとき、右前足揺動軸268の先端は上方に位置しており、左前足161の下端の前後移動幅、即ち左後足181の下端の前後移動幅が大きいとき、右前足171の下端及び右後足191の下端の前後移動幅が小さくなる。   Then, as shown in FIG. 6, when the stride conversion tool 261 is rotated and the tip of the left forefoot swing shaft 267 is positioned at the lower A position, the tip of the right forefoot swing shaft 268 is positioned upward. When the front-rear movement width of the lower end of the left front foot 161, that is, the front-rear movement width of the lower end of the left rear foot 181 is large, the front-rear movement width of the lower end of the right front foot 171 and the lower end of the right rear foot 191 decreases.

また、逆に歩幅変換具261を回転させて左前足揺動軸267の先端を上方のB位置に位置させたとき、右前足揺動軸268の先端は下方に位置しており、左前足161の下端の前後移動幅、即ち左後足181の下端の前後移動幅が小さいとき、右前足171の下端及び右後足191の下端の前後移動幅が大きくなる。   Conversely, when the stride conversion tool 261 is rotated and the tip of the left forefoot rocking shaft 267 is positioned at the upper B position, the tip of the right forefoot rocking shaft 268 is positioned below, and the left forefoot 161 When the front-rear movement width of the lower end of the left rear foot 181 is small, that is, the front-rear movement width of the lower end of the right front foot 171 and the lower end of the right rear foot 191 is larger.

このため、図6に示した左前足揺動軸267の先端を下方のA位置に位置させると、左前足161及び右後足191で歩行玩具100を支えて前進するとき、左前足161の下端の前後動作が大きく右後足191の下端の前後動作が小さくなり、また、右前足171及び左後足181で歩行玩具100を支えて前進するときも、右前足171の下端の前後動作が小さく左後足181の前後動作が大きくなる。   Therefore, when the tip of the left forefoot swing shaft 267 shown in FIG. 6 is positioned at the lower position A, the lower end of the left forefoot 161 is moved forward while supporting the walking toy 100 with the left forefoot 161 and the right rear foot 191. The front / rear motion of the right forefoot 191 is large, and the front / rear motion of the right hind leg 191 is decreased. The front / rear movement of the left hind leg 181 increases.

従って、左前足161及び左後足181による歩行玩具100左側の前進量が右前足171及び右後足191による歩行玩具100右側の前進量よりも大きくなり、歩行玩具100は自然な歩行動作で右側に旋回するように曲進することになる。   Accordingly, the amount of advance on the left side of the walking toy 100 by the left forefoot 161 and the left hind foot 181 is larger than the amount of advance on the right side of the walking toy 100 by the right forefoot 171 and the right hind leg 191. Will turn to turn.

同様に、左前足揺動軸267の先端を上方のB位置に位置させると、左前足161及び右後足191で歩行玩具100を支えて前進するとき、左前足161の下端の前後動作が小さく、右後足191の下端の前後動作が大きく、また、右前足171及び左後足181で歩行玩具100を支えて前進するときは、右前足171の下端の前後動作が大きく、左後足181の前後動作が小さく、左前足161及び左後足181による歩行玩具100左側の前進量が右前足171及び右後足191による歩行玩具100右側の前進量よりも小さくなり、歩行玩具100は自然な歩行動作で左側に旋回するように曲進することになる。   Similarly, when the front end of the left forefoot swing shaft 267 is positioned at the upper B position, when the left forefoot 161 and the right hind leg 191 support the walking toy 100 and moves forward, the front and rear movements of the lower end of the left forefoot 161 are small. When the robot moves forward while supporting the walking toy 100 with the right forefoot 171 and the left hind foot 181, the back and forth movement of the right hind leg 191 is large, and the left hind foot 181 The forward movement of the left toy 100 by the left forefoot 161 and the left hind foot 181 is smaller than the forward movement of the right side of the walking toy 100 by the right forefoot 171 and the right rear foot 191. It turns to turn to the left by walking motion.

尚、左前足161及び右前足171に縦長に設けた揺動軸穴165,175は、下半を左前足揺動軸267や右前足揺動軸268の直径に近くして左前足161及び右前足171の前後移動の規制を強くして左前足161や右前足171の下端を前方に確実に移動させ、揺動軸穴165,175の上方は左前足揺動軸267や右前足揺動軸268の直径よりも大きな前後幅としているため、旋回動作時における前足の前後動作と後足の前後動作の動作幅の相違による連結リンクバー201や前足に等に加わる負荷を吸収しつつ、前足下端の前後移動を歩行玩具100の旋回前進動作に合わせて前足や後足の歩行面の滑りを生じさせることなく自然な歩行を可能としているものである。   Note that the swinging shaft holes 165 and 175 provided vertically on the left forefoot 161 and the right forefoot 171 have the lower half close to the diameters of the left forefoot swing shaft 267 and the right forefoot swing shaft 268, and the left forefoot 161 and the right forefoot 171. The upper and lower movements of the left forefoot 161 and right front foot 171 are securely moved forward, and the upper part of the swing shaft holes 165 and 175 is larger than the diameter of the left forefoot swing shaft 267 and right forefoot swing shaft 268. Therefore, the lower end of the forefoot can be moved back and forth while absorbing the load applied to the connecting link bar 201 and the front foot, etc. In accordance with the turning forward movement of the walking toy 100, natural walking is possible without causing slippage of the walking surface of the forefoot and the rear foot.

また、揺動軸穴165,175における上方の前後幅を左前足揺動軸267や右前足揺動軸268の直径よりも大きくしているため、左前足揺動軸267や右前足揺動軸268が上方に位置するとき、左前足161や右前足171の回転動作に合わせて左前足161や右前足171の上方も前後移動を含む回転運動を行うことが可能となって左前足161や右前足171の下端の前後移動幅が小さくなり、逆の前足は左前足揺動軸267や右前足揺動軸268が揺動軸穴165,175の下方に位置して前足下端の前後移動幅が大きくされ、左前足161の前後移動幅と右前足171の前後移動幅の差が大きくなり、方向変換をより確実に行えることになる。   Further, since the upper front and rear widths of the swing shaft holes 165 and 175 are larger than the diameters of the left forefoot swing shaft 267 and the right forefoot swing shaft 268, the left forefoot swing shaft 267 and the right forefoot swing shaft 268 are When positioned above, the left forefoot 161 and the right forefoot 171 can be rotated and moved forward and backward in accordance with the rotation of the left forefoot 161 and the right forefoot 171. The left and right forefoot swing shaft 267 and the right forefoot swing shaft 268 are positioned below the swing shaft holes 165 and 175 so that the front and rear bottom swing width is increased. The difference between the forward / backward movement width of the foot 161 and the forward / backward movement width of the right front foot 171 increases, and the direction change can be performed more reliably.

そして、上記の説明は前進動作であるも、駆動モータ210を逆回転させることにより、歩行玩具100を後退移動させ、歩幅変換具261を作動させることにより右旋回又は左旋回や直進後退を行わせることができる。   And although the above explanation is a forward movement, the toy 100 is moved backward by rotating the drive motor 210 in the reverse direction, and the right turn or the left turn or the straight forward / backward movement is performed by operating the stride conversion tool 261. Can be made.

このように、本実施の形態における歩行玩具100は、左右の偏心軸237,243により左右の前足161,171に円運動を行わせることにより、前足161,171を持ち上げて前方に移動させ、前足161,171を下して後方に移動させることにより自然な歩行動作を見せることができ、一方の前足を下して後方に移動させるとき、他方の前足を持ち上げており、下した前足と逆側の後ろ足で玩具100を支え、前足161,171の前後動作は後足181,191の前後動作と逆の動きを行うため、玩具100を支える前足と後足の動作が一致して確実に歩行玩具100を前進させることができ、駆動モータ210を逆回転させることにより、歩行玩具100を確実に後退させることができる。   As described above, the walking toy 100 according to the present embodiment causes the left and right front legs 161 and 171 to perform a circular motion with the left and right eccentric shafts 237 and 243, thereby lifting and moving the front legs 161 and 171 forward, lowering the front legs 161 and 171, and It is possible to show a natural walking movement by moving to one side, when lowering one front leg and moving it backward, the other front leg is lifted, supporting the toy 100 with the hind leg on the opposite side of the lowered front leg, The front and rear movements of the front legs 161 and 171 are opposite to the front and rear movements of the rear legs 181 and 191. Therefore, the movements of the front legs and the rear legs that support the toy 100 can be matched and the walking toy 100 can be moved forward reliably. By making the reverse rotation, the walking toy 100 can be reliably retracted.

そして、前足161,171を円運動させる偏心軸237,243の上方に前足161,171の前後移動を規制する上下移動可能な揺動軸267,268を有しているため、偏心軸237,243により円運動をする左右の前足161,171の前後移動を前足161,171の上方で規制して前足161,171の下端を前後移動させるものであるから、上下移動可能な揺動軸267,268を上下させて偏心軸237,243からの距離を変化せると、前足161,171を円運動により上下移動と合わせて前後に移動させる際、前足下端の前後移動量を変化させることができる。   Further, since there are swing shafts 267 and 268 that can move up and down to regulate the front and rear movements of the front legs 161 and 171 above the eccentric shafts 237 and 243 that cause the front legs 161 and 171 to circularly move, the left and right front legs 161 and 171 that perform the circular motion by the eccentric shafts 237 and 243 Since the front and rear movements are restricted above the front legs 161 and 171 and the lower ends of the front legs 161 and 171 are moved back and forth, if the distance from the eccentric shafts 237 and 243 is changed by moving up and down the swing shafts 267 and 268, the front legs 161 and 171 When moving forward and backward along with vertical movement by circular motion, the amount of forward and backward movement of the lower end of the front foot can be changed.

このため、前足161,171の前後移動を規制する上下移動可能な揺動軸267,268を上下移動させることにより、前足161,171ひいては前足161,171に連結リンクバー201で連結された後足181,191の前後移動量を変化させ、左前足161及び左後足181の前後移動幅と右前足171及び右後足191の前後移動幅とに差を生じさせ、左右の前後移動量の差により自然な方向変換を行わせることができる。   For this reason, by moving the swinging shafts 267 and 268 that can move up and down to restrict the front and rear movements of the front legs 161 and 171 up and down, the front legs 161 and 171 and thus the front and rear legs 181 and 191 connected to the front legs 161 and 171 by the connecting link bar 201 are changed. The difference between the front / rear movement width of the left front leg 161 and the left hind leg 181 and the front / rear movement width of the right front leg 171 and the right hind leg 191 is caused, and natural direction change can be performed by the difference of the left / right front / rear movement amount. it can.

更に、左前足揺動軸267と右前足揺動軸268とを一本の可動揺動軸として中央で回転させるようにすれば、左前足揺動軸267を上げるとき右前足揺動軸268を下げ、左前足揺動軸267を下げるとき右前足揺動軸268を上げることができ、左前足161と右前足171との前後移動幅の差を大きくして方向変換歩行を容易且つ確実に行うことができる。   Furthermore, if the left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 are rotated in the center as a single movable rocking shaft, the right forefoot rocking shaft 268 can be When lowering and lowering the left forefoot rocking shaft 267, the right forefoot rocking shaft 268 can be raised, and the difference in the forward and backward movement width between the left forefoot 161 and the right forefoot 171 is increased to make the direction change walking easy and reliable. be able to.

尚、左前足揺動軸267と右前足揺動軸268とを一本の可動揺動軸として左前足161の揺動軸穴165や右前足171の揺動軸穴175に可動揺動軸の端部近傍を挿入する場合に限ることなく、環状のベルトを基台本体113にプーリーを用いて張り渡し、左前足揺動軸267や右前足揺動軸268をベルトから突出させて左前足161の揺動軸穴165や右前足171の揺動軸穴175に挿入し、ベルトの回転により基台本体113の左側でベルトが下降移動するとき基台本体113の右側でベルトが上昇移動するようにして左前足揺動軸267と右前足揺動軸268とを逆方向に移動させることもできる。   The left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 are used as one movable rocking shaft, and the rocking shaft hole 165 of the left forefoot 161 and the rocking shaft hole 175 of the right front foot 171 are connected to the movable rocking shaft. Regardless of the case where the vicinity of the end portion is inserted, an annular belt is stretched around the base body 113 using a pulley, and the left forefoot swing shaft 267 and the right forefoot swing shaft 268 are protruded from the belt so that the left forefoot 161 When the belt moves down on the left side of the base body 113 due to rotation of the belt, the belt moves up on the right side of the base body 113. Thus, the left forefoot rocking shaft 267 and the right forefoot rocking shaft 268 can be moved in the opposite directions.

そして、上述の実施形態は歩行玩具として説明しているも、駆動モータ210の回転を減速して偏心軸237,243を回転させるに際し、減速比を調整して作動足としている前足161,171及び後足181,191の動作を早くすることにより、歩行よりも早い走行動作として歩行玩具100に走行動作を行わせる走行玩具とすることもある。   And although the above-mentioned embodiment has been described as a walking toy, when the eccentric shafts 237 and 243 are rotated by decelerating the rotation of the drive motor 210, the front feet 161 and 171 and the rear feet 181 and 191 that are operating feet are adjusted by adjusting the reduction ratio. By making the operation faster, it may be a traveling toy that causes the walking toy 100 to perform the traveling operation as a traveling operation faster than walking.

また、図に示した歩行玩具100は、四足歩行玩具100であるも、前足や後足よりも僅かに短い中間足を前足と後足の間に設けた多足動物の形状とすることもある。   Further, the walking toy 100 shown in the figure is a quadruped walking toy 100, but it may have a shape of a multi-legged animal in which an intermediate foot slightly shorter than the front foot and the rear foot is provided between the front foot and the rear foot. is there.

この場合も、中間足は前足や後足よりも短く、歩行動作における歩行玩具100の支持は前足と後足で行うものであり、中間足は前足や後足と同様の足形状とした装飾足として設けることにより、種々の多足動物などの歩行動物の形状を模した歩行玩具100または走行玩具とすることができる。   Also in this case, the intermediate foot is shorter than the front foot and the rear foot, and the walking toy 100 is supported by the front foot and the rear foot during the walking motion, and the intermediate foot is a decorative foot having the same foot shape as the front foot and the rear foot. By providing as the walking toy 100 or the traveling toy imitating the shape of a walking animal such as various multi-legged animals.

そして、装飾足は、基台本体113に取り付けるに際し、前足と後足との中間位置に限ることなく、前足よりも前方または後足よりも後方にも配置することにより、多くの中間足などの装飾足を前足と後足に追加することが容易に可能となる。   In addition, when the decorative foot is attached to the base body 113, it is not limited to the middle position between the front foot and the rear foot, but it is also disposed forward of the front foot or rearward of the rear foot. It becomes easy to add decorative feet to the front and rear feet.

更に、この歩行玩具100を支持しない長さとする装飾足としては、下端を前後に揺動可能に基台本体113に取り付け、各装飾足を後足と連結バーを用いて連結することにより、後足の前後動作に合わせて装飾足も前後に移動させて見た目には自然な歩行状態とすることもできる。   Furthermore, as a decorative foot having a length that does not support the walking toy 100, the lower end is attached to the base body 113 so as to be swingable back and forth, and each decorative foot is connected to the rear foot using a connecting bar, thereby The decorative foot can also be moved back and forth in accordance with the back and forth movement of the foot to make it a natural walking state.
