以下、本発明の実施の形態について、図を参照して説明する。
図１に、本実施の形態におけるオフロード用のリモコン玩具１の外観図を示す。リモコン玩具１は、本発明に係る自動車玩具２と、この自動車玩具２を無線で操作するリモコン３とからなり、平地だけでなく、砂利や土などの非舗装路面で自動車玩具２を走行させて遊ぶことのできる玩具である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an external view of an off-road remote control toy 1 according to the present embodiment. The remote control toy 1 includes a car toy 2 according to the present invention and a remote control 3 for operating the car toy 2 wirelessly, and the car toy 2 is driven not only on a flat ground but also on a non-paved road surface such as gravel or soil. It is a toy that can be played.

図２及び図３に、自動車玩具２からボディ１１を取り外した状態の上面図及び側面図を示す。自動車玩具２は、左右の前輪２０，２０を繋ぐ前輪用車軸２１が軸支される前輪用シャーシ２２と、左右の後輪３０，３０を繋ぐ後輪用車軸３１が軸支される後輪用シャーシ３２とを備える。この前輪用シャーシ２２と後輪用シャーシ３２とは、両側面の２箇所に設けられた連結部４０によって両車軸の中途部で連結されている。なお、この「両車軸の中途部」とは、シャーシの前後方向における前輪用車軸２１と後輪用車軸３１との間の位置を意味している。   2 and 3 are a top view and a side view of the state where the body 11 is removed from the car toy 2. The toy car 2 is for a rear wheel on which a front wheel chassis 22 that supports the front wheel axle 21 that connects the left and right front wheels 20 and 20 and a rear wheel axle 31 that connects the left and right rear wheels 30 and 30 are supported. A chassis 32. The front wheel chassis 22 and the rear wheel chassis 32 are connected to each other in the middle of both axles by connecting portions 40 provided at two locations on both side surfaces. The “middle part of both axles” means a position between the front wheel axle 21 and the rear wheel axle 31 in the longitudinal direction of the chassis.

前輪用シャーシ２２は、前輪用車軸２１と連結部４０との間に収納スペースを有し、この収納スペースには、リモコン３からの無線信号を受信する受信装置５０と、受信した無線信号により各部を制御する制御部５１と、制御部５１からの指令で前輪を操舵するステアリング装置（図示せず）とが配設されている。また、制御部５１と収納スペース底面との間には、電力を供給する電池（図示せず）が収納されている。そして、この前輪用シャーシ２２にはボディ１１が係止されている。   The front wheel chassis 22 has a storage space between the front wheel axle 21 and the connecting portion 40. In this storage space, a receiving device 50 that receives a radio signal from the remote control 3, and each part by the received radio signal. And a steering device (not shown) for steering the front wheels in response to a command from the control unit 51. Further, a battery (not shown) for supplying electric power is stored between the control unit 51 and the bottom surface of the storage space. The body 11 is locked to the front wheel chassis 22.

後輪用シャーシ３２は、後輪用車軸３１を介して後輪３０を駆動するモータ５３を備えている。モータ５３は、前輪用シャーシ２２に配設された制御部５１及び図示しない電池から、連結部４０を介して駆動指令及び電力供給を受ける。   The rear wheel chassis 32 includes a motor 53 that drives the rear wheel 30 via the rear wheel axle 31. The motor 53 receives a drive command and power supply from the control unit 51 disposed in the front wheel chassis 22 and a battery (not shown) via the connection unit 40.

２箇所の連結部４０は、図２に示すように、車幅方向に延在する回動軸４４を中心に回動可能に連結している。この２箇所の連結部４０は互いに車幅方向に離れているので、両シャーシがこの連結部４０で捻れることを抑制し、回動軸４４の回動を安定させる。なお、この回動軸４４は図４に示すように後輪３０寄りの位置でボディ１１の後輪部のフェンダー１２の下方に位置している。 As shown in FIG. 2, the two connecting portions 40 are connected so as to be rotatable about a rotating shaft 44 extending in the vehicle width direction. Since the two connecting portions 40 are separated from each other in the vehicle width direction, the two chassis are prevented from being twisted by the connecting portion 40 and the rotation of the rotating shaft 44 is stabilized. As shown in FIG. 4, the pivot shaft 44 is positioned below the fender 12 in the rear wheel portion of the body 11 at a position near the rear wheel 30.

また、図３に示すように、この連結部４０における前輪用シャーシ２２と後輪用シャーシ３２との回動範囲はＡストッパ面４１，４１及びＢストッパ面４２，４２によって規制される。具体的には、連結部４０の下方寄りの前輪用シャーシ２２側と後輪用シャーシ３２側には、それぞれＡストッパ面４１，４１が形成されている。このＡストッパ面４１，４１は、図３（ａ）に示すように、互いに当接することで連結部４０が路面から離間する方向への回動を制限する。同様に、連結部４０の上方寄りの前輪用シャーシ２２側と後輪用シャーシ３２側には、それぞれＢストッパ面４２，４２が形成されている。このＢストッパ面４２，４２は、図３（ｂ）に示すように、互いに当接することで連結部４０が路面へ接近する方向への回動を制限する。   As shown in FIG. 3, the rotation range of the front wheel chassis 22 and the rear wheel chassis 32 in the connecting portion 40 is restricted by the A stopper surfaces 41 and 41 and the B stopper surfaces 42 and 42. Specifically, A stopper surfaces 41 and 41 are respectively formed on the front wheel chassis 22 side and the rear wheel chassis 32 side near the lower side of the connecting portion 40. As shown in FIG. 3A, the A stopper surfaces 41 and 41 abut against each other to limit the rotation of the connecting portion 40 in the direction away from the road surface. Similarly, B stopper surfaces 42 and 42 are formed on the front wheel chassis 22 side and the rear wheel chassis 32 side near the upper side of the connecting portion 40, respectively. As shown in FIG. 3B, the B stopper surfaces 42 and 42 abut against each other, thereby restricting rotation of the connecting portion 40 in a direction approaching the road surface.

なお、Ａストッパ面４１，４１の当接位置は、両シャーシの傾斜がオフロード用の自動車としての外観を損ねない程度であるように設定され、Ｂストッパ面４２，４２の当接位置は、シャーシ底面が路面と接触しないように設定される。   The contact positions of the A stopper surfaces 41 and 41 are set so that the inclination of both chassis does not impair the appearance as an off-road vehicle, and the contact positions of the B stopper surfaces 42 and 42 are The bottom of the chassis is set so as not to contact the road surface.

連結部４０の一方（図２における下方側，図３における手前側）には、捻りばね４３が配設されている。この捻りばね４３はシャーシの片側において回動軸４４に巻き掛けられ、その一端が前輪用シャーシ２２に他端が後輪用シャーシ３２に係止されている。この捻りばね４３はシャーシの外側に設けられることが好ましい。シャーシの外側に捻りばね４３を設けることとすれば、シャーシ内側に他の部品のためのスペースを確保することができる。
捻りばね４３は、連結部４０が水平路面上で両車軸に対して上方に位置する状態、すなわち、図３（ａ）の状態になるよう当該連結部４０を付勢する付勢手段として機能する。また、捻りばね４３は、自動車玩具２に加わる上下方向への振動を吸収するショックアブソーバとして機能する。したがって、自動車玩具２は複雑なサスペンション装置を備える必要がない。更に、この捻りばね４３は両シャーシが屈曲状態となるように付勢するので、自動車玩具２の全長を短くすることができる。 A torsion spring 43 is disposed on one side of the connecting portion 40 (the lower side in FIG. 2 and the near side in FIG. 3). The torsion spring 43 is wound around the rotation shaft 44 on one side of the chassis, and one end thereof is locked to the front wheel chassis 22 and the other end is locked to the rear wheel chassis 32. The torsion spring 43 is preferably provided outside the chassis. If the torsion spring 43 is provided outside the chassis, a space for other components can be secured inside the chassis.
The torsion spring 43 functions as a biasing means for biasing the connecting portion 40 so that the connecting portion 40 is positioned above the two axles on the horizontal road surface, that is, the state shown in FIG. . Further, the torsion spring 43 functions as a shock absorber that absorbs vertical vibration applied to the automobile toy 2. Therefore, the car toy 2 does not need to have a complicated suspension device. Furthermore, since the torsion spring 43 urges both chassis to be bent, the overall length of the toy car 2 can be shortened.

なお、ボディ１１は前輪用シャーシ２２のみに固定されるため連結部４０の回動を阻害することはない。加えて、ボディ１１の後輪部のフェンダー１２（図４参照）と後輪３０とは、Ｂストッパ面４２，４２が当接する（図３（ｂ））状態においても両者が接触しないようクリアランス設定されるが、捻りばね４３に付勢される通常（図３（ａ））の状態では両シャーシが上方に向かって連結されているので、前輪用シャーシ２２に固定されるボディ１１の後輪側は上方へ持ち上げられ、フェンダー１２と後輪３０とのクリアランスを容易に確保できる。
また、例えば、ボディ１１を前輪用ボディと後輪用ボディとに分割して、シャーシと同様に互いに回動可能に連結しておくなど、この前輪用ボディと後輪用ボディとを、連結部４０の回動を阻害しないよう前輪用シャーシ２２と後輪用シャーシ３２とにそれぞれ固定するようにしてもよい。 Since the body 11 is fixed only to the front wheel chassis 22, the rotation of the connecting portion 40 is not hindered. In addition, the fender 12 (see FIG. 4) at the rear wheel portion of the body 11 and the rear wheel 30 are set so that the B stopper surfaces 42 and 42 are in contact with each other even when the B stopper surfaces 42 and 42 are in contact (FIG. 3B). However, in the normal state (FIG. 3A) urged by the torsion spring 43, both chassis are connected upward, so that the rear wheel side of the body 11 fixed to the front wheel chassis 22 is provided. Is lifted upward, and the clearance between the fender 12 and the rear wheel 30 can be easily secured.
In addition, for example, the body 11 is divided into a front wheel body and a rear wheel body, and the front wheel body and the rear wheel body are connected to each other in the same manner as the chassis. You may make it fix to the front-wheel chassis 22 and the rear-wheel chassis 32 so that rotation of 40 may not be inhibited.

続いて、本実施の形態におけるリモコン玩具１の概略動作を説明する。   Subsequently, a schematic operation of the remote control toy 1 in the present embodiment will be described.

リモコン玩具１は、リモコン３を操作することによって自動車玩具２を思いのままに走行させることができる。まず、リモコン３からは操作に応じた無線信号が発せられ、この無線信号が自動車玩具２の受信装置５０で受信される。そして、その無線信号を受けた制御部５１からの指令により、ステアリングサーボ５２又はモータ５３等が操舵動作又は後輪３０の駆動動作等をすることによって、自動車玩具２をリモコン３の操作通りに走行させることができる。   The remote control toy 1 can drive the automobile toy 2 as desired by operating the remote control 3. First, a radio signal corresponding to the operation is emitted from the remote controller 3, and this radio signal is received by the receiving device 50 of the car toy 2. The steering servo 52 or the motor 53 performs a steering operation or a driving operation of the rear wheel 30 in accordance with a command from the control unit 51 that has received the radio signal, so that the vehicle toy 2 travels as operated by the remote controller 3. Can be made.

続いて、凹凸路面走行時における自動車玩具２の動作を詳細に説明する。   Next, the operation of the automobile toy 2 when traveling on an uneven road will be described in detail.

図４に、凸部を有する路面の走行時における自動車玩具２の側面図を示す。
自動車玩具２が凸部を有する路面を走行する際は、まず、前輪２０が凸部を乗り越える。このとき、捻りばね４３によって両シャーシが屈曲状態に付勢されているため、前輪２０は強いグリップ力で凸部を乗り越えることができる。また、自動車玩具２に上下方向への振動が加わるが、捻りばね４３がショックアブソーバとして働き、この振動を吸収するため、自動車玩具２への衝撃が緩和される。更に、フェンダー１２と後輪３０とのクリアランスは充分に確保できているため、自動車玩具２が上下に振動したときでも、両者が接触することはない。 FIG. 4 shows a side view of the automobile toy 2 when traveling on a road surface having a convex portion.
When the automobile toy 2 travels on a road surface having a convex portion, first, the front wheel 20 gets over the convex portion. At this time, since both the chassis are biased by the torsion spring 43, the front wheel 20 can get over the convex portion with a strong grip force. Moreover, although the vertical vibration is applied to the automobile toy 2, the torsion spring 43 functions as a shock absorber and absorbs this vibration, so that the impact on the automobile toy 2 is reduced. Furthermore, since the clearance between the fender 12 and the rear wheel 30 is sufficiently secured, even when the automobile toy 2 vibrates up and down, they do not contact each other.

次に、図４に示すように、前輪用シャーシ２２と後輪用シャーシ３２とが凸部を跨ぐ。このとき、前輪用シャーシ２２と後輪用シャーシ３２とが、前後輪の車軸間で路面から離間するよう上方に凹部を形成して連結されているので、路面の凸部と両シャーシの腹部とが接触することなく走行できる。   Next, as shown in FIG. 4, the front wheel chassis 22 and the rear wheel chassis 32 straddle the convex portion. At this time, the front wheel chassis 22 and the rear wheel chassis 32 are connected to each other by forming a concave portion on the upper side so as to be separated from the road surface between the front and rear wheel axles. Can travel without touching.

最後に、後輪３０が凸部を乗り越える。このとき、捻りばね４３によって両シャーシが屈曲状態に付勢されているため、後輪２０は強いグリップ力で凸部を乗り越えることができる。また、自動車玩具２に上下方向への振動が加わるが、捻りばね４３がショックアブソーバとして働き、この振動を吸収するため、自動車玩具２への衝撃が緩和される。更に、フェンダー１２と後輪３０とのクリアランスは充分に確保できているため、自動車玩具２が上下に振動したときでも、両者が接触することはない。   Finally, the rear wheel 30 gets over the convex portion. At this time, since both chassis are urged in a bent state by the torsion spring 43, the rear wheel 20 can get over the convex portion with a strong grip force. Moreover, although the vertical vibration is applied to the automobile toy 2, the torsion spring 43 functions as a shock absorber and absorbs this vibration, so that the impact on the automobile toy 2 is reduced. Furthermore, since the clearance between the fender 12 and the rear wheel 30 is sufficiently secured, even when the automobile toy 2 vibrates up and down, they do not contact each other.

以上のように、本発明に係るリモコン玩具１によれば、捻りばね４３が両シャーシを屈曲状態に付勢するので、起伏の大きい路面走行の場合でも前後輪の強いグリップ力が得られる。また、両シャーシは常態で屈曲状態に保持されるため、自動車玩具２の全長を短くすることができる。   As described above, according to the remote-control toy 1 according to the present invention, the torsion springs 43 urge both chassis in a bent state, so that a strong grip force between the front and rear wheels can be obtained even when the road surface has a large undulation. Moreover, since both chassis are normally hold | maintained at a bending state, the full length of the toy car 2 can be shortened.

また、捻りばね４３がショックアブソーバとして働き、自動車玩具２に加わる上下方向の振動を吸収するため、複雑なサスペンション装置を備える必要なく自動車玩具２への衝撃が緩和できる。   Further, since the torsion spring 43 functions as a shock absorber and absorbs the vertical vibration applied to the automobile toy 2, the impact on the automobile toy 2 can be reduced without the need for providing a complicated suspension device.

また、捻りばね４３はシャーシの片側において回動軸４４に巻き掛けられ、その一端が前輪用シャーシ２２に他端が後輪用シャーシ３２に係止されているので、捻りばね４３は１つだけでショックアブソーバとして車体への衝撃を緩和できる。更に、この捻りばね４３はシャーシの外側に設けられているので、シャーシ内側に他の部品のためのスペースを確保することができる。   Further, the torsion spring 43 is wound around the rotating shaft 44 on one side of the chassis, and one end thereof is locked to the front wheel chassis 22 and the other end is locked to the rear wheel chassis 32, so that only one torsion spring 43 is provided. As a shock absorber, the impact on the vehicle body can be reduced. Further, since the torsion spring 43 is provided outside the chassis, a space for other parts can be secured inside the chassis.

また、前輪用シャーシ２２と後輪用シャーシ３２とを連結する２箇所の連結部４０は互いに車幅方向に離れているので、両シャーシがこの連結部４０で捻れることを抑制し、回動軸４４の回動を安定させる。   In addition, since the two connecting portions 40 that connect the front wheel chassis 22 and the rear wheel chassis 32 are separated from each other in the vehicle width direction, the two chassis are prevented from being twisted by the connecting portions 40 and are rotated.
