Description
本発明は、折曲可能なジョイントに関する。 This invention relates to a bendable joint.
この種のジョイントとしては、従来、種々のものが提案されている。 Various types of joints have been proposed in the past.
たとえば特許文献１には、固定側連結部と可動側連結部をヒンジと四節リンク機構を用いて折曲可能に構成したロック機構が開示されている。 For example, Patent Document 1 discloses a locking mechanism in which the fixed-side connecting portion and the movable-side connecting portion are configured to be foldable using a hinge and a four-bar linkage mechanism.
しかしながら、固定側連結部と可動側連結部の一側をヒンジで連結するとともに、四節リンク機構を固定側連結部と可動側連結部と他の二つのリンクで構成するため、固定側連結部と可動側連結部のヒンジの反対側に二つのリンクが位置するため、折曲角度が制限されるという課題がある。 However, because the fixed and movable connecting parts are connected by a hinge on one side, and the four-bar linkage mechanism is composed of the fixed, movable, and two other links, there is a problem in that the bending angle is limited because the two links are located on the opposite side of the hinge between the fixed and movable connecting parts.
しかも、固定側連結部と可動側連結部の連結状態では、ヒンジと二つのリンクで連結するため、強度的に問題がある。 Furthermore, the connection between the fixed and movable connecting parts is structurally problematic because it relies on a hinge and two links.
本発明は、上記事情に基づいてなされたもので、その目的とするところは、折曲角度の制限を可及的に無くすことができ、しかも連結強度を向上させることができるようにしたジョイントを提供することにある。 This invention was made based on the above circumstances, and its objective is to provide a joint that can minimize the limitations on the bending angle and improve the connection strength.
上記課題を解決するために、本発明に係るジョイントは、第１継手部と、この第１継手部に連結可能な第２継手部と、第１継手部と第２継手部とを、第１継手部と第２継手部とが連結する伸展状態から第１継手部と第２継手部とが分離する折曲状態まで、回動可能に支持するヒンジ部とを具備し、第１継手部は、第２継手部に接離可能に設けられたストッパ部材と、このストッパ部材を第２継手部に圧接させて第１継手部と第２継手部とを連結状態に保持するとともにストッパ部材の第２継手部への圧接を解除して第１継手部と第２継手部との連結状態を解除するための操作部材と、を備え、前記第２継手部は、前記第１継手部との連結解除状態を示す連結解除表示部を備えたことを特徴とするものである。 To solve the above problems, the joint according to the present invention comprises a first joint portion, a second joint portion connectable to the first joint portion, and a hinge portion that rotatably supports the first joint portion and the second joint portion from an extended state in which the first joint portion and the second joint portion are connected to a bent state in which the first joint portion and the second joint portion are separated, wherein the first joint portion comprises a stopper member provided to be able to move toward and away from the second joint portion, and an operating member for pressing the stopper member toward the second joint portion to hold the first joint portion and the second joint portion in a connected state and releasing the pressure of the stopper member toward the second joint portion to release the connected state between the first joint portion and the second joint portion, wherein the second joint portion is provided with a connection release indicator portion that indicates the state of disconnection from the first joint portion .
本発明に係るジョイントによれば、折曲角度に制限が無く、しかも強度を可及的に向上させることができる。 According to the joint of the present invention, there are no restrictions on the bending angle, and the strength can be improved as much as possible.
図面は、本開示に係る本発明の特定の実施の形態を示し、発明の不可欠な構成ばかりでなく、選択的及び好ましい実施の形態を含む。
以下、本発明の一実施形態について図面を参照しながら説明する。 The following describes one embodiment of the present invention with reference to the drawings.
図１中、符号１は、本発明の一実施形態に係るジョイント２を用いたドローンを示している。 In Figure 1, reference numeral 1 denotes a drone using joint 2 according to one embodiment of the present invention.
このドローン１は、胴体３を有し、この胴体３から放射状にたとえば４本の筒状のアーム４が延出され、各アーム４の先端にはプロペラ５が取付けられている。 This drone 1 has a body 3, from which, for example, four cylindrical arms 4 extend radially, with a propeller 5 attached to the end of each arm 4.
また、各アーム４は、胴体３の側の基端側アーム部材６と、プロペラ５の側の先端側アーム部材７とに分割して構成され、基端側アーム部材６と先端側アーム部材７はジョイント２によって連結されている。 Furthermore, each arm 4 is divided into a base arm member 6 on the fuselage 3 side and a tip arm member 7 on the propeller 5 side, and the base arm member 6 and the tip arm member 7 are connected by a joint 2.
そして、アーム４は、図２に示すように、ジョイント２によってたとえば水平方向へ折曲げる（折畳む）ことができるようになっている。 Furthermore, as shown in Figure 2, the arm 4 can be bent (folded) horizontally, for example, by the joint 2.
ジョイント２は、図３および図４に示すように、第１継手部８と、この第１継手部８に連結可能な第２継手部９を備え、これら第１継手部８と第２継手部９はヒンジ部１０によって回動可能に支持されている。 As shown in Figures 3 and 4, joint 2 comprises a first joint portion 8 and a second joint portion 9 connectable to the first joint portion 8. These first joint portion 8 and second joint portion 9 are rotatably supported by a hinge portion 10.
そして、第１継手部８と第２継手部９とが対向して連結する伸展状態と、図５および図６に示すように、第１継手部８と第２継手部９とが分離する折曲状態とを呈することができるように構成されている。 Furthermore, the structure is configured to exhibit both an extended state in which the first joint portion 8 and the second joint portion 9 are connected and facing each other, and a bent state in which the first joint portion 8 and the second joint portion 9 are separated, as shown in Figures 5 and 6.
これにより、アーム４は、ジョイント２により伸展したり折曲たりすることが可能となっている。 This allows arm 4 to extend and bend via joint 2.
第１継手部８は、基端側アーム部材６の先端に外嵌する筒状の第１取付部１１を有している。 The first joint portion 8 has a cylindrical first mounting portion 11 that fits onto the tip of the base-end arm member 6.
この第１取付部１１には、基端側から軸方向に沿って切り込んだ第１スリット１２が形成されている。 A first slit 12 is formed in this first mounting portion 11, cut axially from the base end.
この第１スリット１２の両側には、一対の第１締付部１３が径方向外方へ突設されている。 A pair of first clamping portions 13 are provided projecting radially outward from both sides of the first slit 12.
これら第１締付部１３には貫通孔１４が形成されていて、図７および図８に示すように、この貫通孔１４にボルト１５を挿通させナット１６で締め付けることにより第１スリット１２が狭められて第１取付部１１が縮径され、これにより第１取付部１１が基端側アーム部材６に嵌着されるようになっている。 These first fastening portions 13 have through holes 14. As shown in Figures 7 and 8, by inserting a bolt 15 through these through holes 14 and tightening it with a nut 16, the first slit 12 is narrowed, reducing the diameter of the first mounting portion 11. This allows the first mounting portion 11 to be fitted onto the base end arm member 6.
さらに、第１取付部１１の側部には穴１７が形成され、この穴１７にリベット１８を差込んでかしめることにより第１取付部１１が基端側アーム部材６に固定されるようになっている。 Furthermore, a hole 17 is formed in the side of the first mounting portion 11, and the first mounting portion 11 is fixed to the base end arm member 6 by inserting a rivet 18 into this hole 17 and crimping it.
第２継手部９は、先端側アーム部材７の基端に外嵌する筒状の第２取付部２１を有している。 The second joint portion 9 has a cylindrical second mounting portion 21 that fits onto the base end of the tip-side arm member 7.
この第２取付部２１には、先端側から軸方向に沿って切り込んだ第２スリット２２が形成されている。 A second slit 22 is formed in this second mounting portion 21, cut axially from the tip side.
この第２スリット２２の両側には、一対の第２締付部２３が径方向外方へ突設されている。 A pair of second clamping portions 23 are provided projecting radially outward from both sides of the second slit 22.
これら第２締付部２３には貫通孔２４が形成されていて、この貫通孔２４にボルト２５を挿通させナット２６で締め付けることにより第２スリット２２が狭められて第２取付部２１が縮径され、これにより第２取付部２１が先端側アーム部材７に嵌着されるようになっている。 These second fastening portions 23 have through holes 24. By inserting a bolt 25 through these through holes 24 and tightening it with a nut 26, the second slit 22 is narrowed, reducing the diameter of the second mounting portion 21. This allows the second mounting portion 21 to be fitted onto the tip-side arm member 7.
さらに、第２取付部２１の側部には穴２７が形成され、この穴２７にリベット２８を差込んでかしめることにより第２取付部２１が先端側アーム部材７に固定されるようになっている。 Furthermore, a hole 27 is formed on the side of the second mounting portion 21, and the second mounting portion 21 is fixed to the tip-side arm member 7 by inserting a rivet 28 into this hole 27 and crimping it.
また、第２継手部９には、第２取付部２１と反対側に、第２取付部２１より小径の管状の内嵌部３１が形成され、この内嵌部３１と第２取付部２１は連通されている。 Furthermore, the second joint portion 9 has a tubular inner fitting portion 31 with a smaller diameter than the second mounting portion 21, on the side opposite to the second mounting portion 21, and this inner fitting portion 31 and the second mounting portion 21 are in communication.
この内嵌部３１の外周部は、図９～図１２にも示すように、先端側程縮径する略テーパ状に形成され、第２取付部２１の側から順に、大径の第１環状溝３２、中径の第２環状溝（凹部）３３、小径の第３環状溝３４が形成されている。 As shown in Figures 9 to 12, the outer circumference of this inner fitting portion 31 is formed in a substantially tapered shape, becoming smaller in diameter towards the tip. Starting from the side of the second mounting portion 21, a large-diameter first annular groove 32, a medium-diameter second annular groove (recess) 33, and a small-diameter third annular groove 34 are formed in that order.
そして、第１環状溝３２には第１継手部８と第２継手部９との連結状態が解除されていること（第１継手部８と第２継手部９との分離状態）を表示するための弾性を有する大径の第１Ｏリング（連結解除表示部）３５が外嵌され、第３環状溝３４には弾性を有する小径の第２Ｏリング３６が外嵌されている。 Furthermore, a large-diameter, elastic first O-ring (disconnection indicator) 35 is fitted onto the first annular groove 32 to indicate that the connection between the first joint 8 and the second joint 9 has been released (the first joint 8 and the second joint 9 are separated), and a small-diameter, elastic second O-ring 36 is fitted onto the third annular groove 34.
一方、第１継手部８には、第１取付部１１と反対側に、第１取付部１１より小径の管状の外嵌部４１が形成され、この外嵌部４１と第１取付部１１は連通されている。 On the other hand, the first joint portion 8 has a tubular outer fitting portion 41 with a smaller diameter than the first mounting portion 11 formed on the side opposite to the first mounting portion 11, and this outer fitting portion 41 and the first mounting portion 11 are in communication.
この外嵌部４１は第１継手部８と第２継手部９との連結状態では内嵌部３１に外嵌するように構成されている。 This outer fitting portion 41 is configured to fit onto the inner fitting portion 31 when the first joint portion 8 and the second joint portion 9 are connected.
また、この外嵌部４１の内周部は、先端側程拡径する略テーパ状に形成され、第１継手部８と第２継手部９との連結状態では第１Ｏリング３５と第２Ｏリング３６に圧接するように構成されている。 Furthermore, the inner circumference of the outer fitting portion 41 is formed in a substantially tapered shape, increasing in diameter towards the tip, and is configured to press against the first O-ring 35 and the second O-ring 36 when the first joint portion 8 and the second joint portion 9 are connected.
この外嵌部４１の第１Ｏリング３５と第２Ｏリング３６が圧接する部分の間には、複数の貫通穴４２が周方向に間隔を開けて形成され、この貫通穴４２には、たとえばナイロン製などの弾性を有するボール（ストッパ部材）４３が遊嵌（収容）されている。 Between the portion of the outer fitting 41 where the first O-ring 35 and the second O-ring 36 are pressed together, a plurality of through-holes 42 are formed at circumferential intervals. Elastic balls (stopper members) 43, such as those made of nylon, are loosely fitted (housed) in these through-holes 42.
この貫通穴４２は、外嵌部４１の外周側より内周側の方が小径に形成され、ボール４３は、外嵌部４１の外周側から嵌入され、周面の一部が内周側へ突出することができるが、通り抜けできない大きさに形成されている。 This through-hole 42 is formed with a smaller diameter on the inner side than on the outer side of the outer fitting portion 41. The ball 43 is inserted from the outer side of the outer fitting portion 41, and a portion of its circumferential surface can protrude towards the inner side, but it is formed to be too small to pass through completely.
そして、ボール４３は、貫通穴４２から突出した状態では第２環状溝３３内に圧接して内嵌部３１を周囲から押えるように構成されていて、これにより第１継手部８と第２継手部９との連結状態が保持されるようになっている。 Furthermore, the ball 43 is configured to press against the second annular groove 33 when protruding from the through hole 42, thereby pressing the inner fitting portion 31 from the surroundings. This maintains the connection between the first joint portion 8 and the second joint portion 9.
また、この貫通穴４２およびボール４３は、ヒンジ部１０と反対側に多く設けられていて、ヒンジ部１０方向に向けてより強固に押圧できるようになっている。 Furthermore, the through-holes 42 and balls 43 are more frequently provided on the side opposite the hinge portion 10, allowing for stronger pressure in the direction of the hinge portion 10.
さらに、外嵌部４１の外周側には、ボール４３を第２継手部９に当接させて第１継手部８と第２継手部９とを連結状態に保持するとともにボール４３の第２継手部９への当接を解除するための操作部材５０が設けられている。 Furthermore, an operating member 50 is provided on the outer circumference of the outer fitting portion 41 to hold the first joint portion 8 and the second joint portion 9 in a connected state by bringing the ball 43 into contact with the second joint portion 9, and to release the contact of the ball 43 with the second joint portion 9.
この操作部材５０は、第２継手部９に対し接離可能なスライダ（接離部材）５１とこのスライダ５１を付勢する圧縮コイルばね（付勢部材）５２を有している。 This operating member 50 has a slider (connecting/separating member) 51 that can move toward and away from the second joint 9, and a compression coil spring (biasing member) 52 that biases the slider 51.
スライダ５１は、外嵌部４１に軸方向にスライド自在に外嵌される環状に形成されている。 The slider 51 is formed in an annular shape so as to slide freely in the axial direction when fitted onto the outer fitting portion 41.
圧縮コイルばね５２は、スライダ５１と外嵌部４１との間に嵌め込まれ、スライダ５１を第１取付部１１と反対方向へ付勢するように構成されている。 The compression coil spring 52 is fitted between the slider 51 and the outer fitting portion 41, and is configured to bias the slider 51 in the direction opposite to the first mounting portion 11.
また、スライダ５１の内周側には、ボール４３を貫通穴４２から外嵌部４１の内周側へ突出した状態に保持する凸部５３と、スライダ５１を圧縮コイルばね５２の付勢力に抗してスライドさせた状態でボール４３を外嵌部４１の内周側から退避させるための凹部５４が形成されている。 Furthermore, the inner circumference of the slider 51 is formed with a protrusion 53 that holds the ball 43 in a position protruding from the through hole 42 toward the inner circumference of the outer fitting portion 41, and a recess 54 that retracts the ball 43 from the inner circumference of the outer fitting portion 41 when the slider 51 is slid against the biasing force of the compression coil spring 52.
さらに、外嵌部４１の第１取付部１１側には、第４環状溝５５が形成され、この第４環状溝５５には、第１継手部８と第２継手部９とが連結状態であることを表示するための弾性を有する第３Ｏリング（連結表示部）５６が外嵌されている。 Furthermore, a fourth annular groove 55 is formed on the first mounting portion 11 side of the outer fitting portion 41, and an elastic third O-ring (connection indicator portion) 56 is fitted into this fourth annular groove 55 to indicate that the first joint portion 8 and the second joint portion 9 are connected.
この第３Ｏリング５６は、スライダ５１が圧縮コイルばね５２の付勢力に抗してスライドしたときにスライダ５１に覆われ隠れるように構成されている。 This third O-ring 56 is configured to be covered and hidden by the slider 51 when the slider 51 slides against the biasing force of the compression coil spring 52.
また、スライダ５１には径方向外方へ張り出す一対の取手５７が設けられ、片手でスライダ５１の操作が行えるように構成されている。 Furthermore, the slider 51 is provided with a pair of handles 57 that protrude radially outward, allowing the slider 51 to be operated with one hand.
さらに、第２継手部９のヒンジ部１０と反対側には第１継手部８の方向へ突出する嵌合凸部５８が形成されている。 Furthermore, a fitting projection 58 is formed on the side of the second joint portion 9 opposite to the hinge portion 10, projecting toward the first joint portion 8.
一方、第１継手部８には、第１継手部８と第２継手部９との連結状態で嵌合凸部５８が嵌合する嵌合凹部５９が形成されている。 On the other hand, the first joint portion 8 has a fitting recess 59 into which the fitting projection 58 fits when the first joint portion 8 and the second joint portion 9 are connected.
ヒンジ部１０は、第１継手部８に固定される第１ヒンジ片６１と、第２継手部９に固定される第２ヒンジ片６２と、これら第１ヒンジ片６１と第２ヒンジ片６２とを回動自在に連結する軸６３を備えている。 The hinge portion 10 comprises a first hinge piece 61 fixed to the first joint portion 8, a second hinge piece 62 fixed to the second joint portion 9, and a shaft 63 that rotatably connects the first hinge piece 61 and the second hinge piece 62.
この軸６３は、第２継手部９に一対のカラー６４を介して取り付けられている。 This shaft 63 is attached to the second joint 9 via a pair of collars 64.
また、スライダ５１の周面部６５には凸部６６が設けられ、この凸部６６は、第１継手部８と第２継手部９とが分離し連結が解除された状態では第２ヒンジ片６２の周面部（規制部）６７に当接し、スライダ５１を圧縮コイルばね５２の付勢力に抗して変位した状態に保持するようになっている。 Furthermore, a protrusion 66 is provided on the circumferential surface 65 of the slider 51. This protrusion 66 contacts the circumferential surface (restricting portion) 67 of the second hinge piece 62 when the first joint 8 and the second joint 9 are separated and the connection is released, thereby holding the slider 51 in a displaced state against the biasing force of the compression coil spring 52.
さらに、第２ヒンジ片６２の周面部６７には第１継手部８と第２継手部９とが連結された状態で凸部６６が退避することが可能な凹部６８が形成され、この凹部６８に凸部６６が退避することによりスライダ５１がボール４３を押圧する位置まで移動できるようになっている。 Furthermore, a recess 68 is formed on the circumferential surface 67 of the second hinge piece 62, allowing the protrusion 66 to retract while the first joint 8 and the second joint 9 are connected. By retracting the protrusion 66 into this recess 68, the slider 51 can move to the position where it presses against the ball 43.
このような構成において、図１に示すように、ドローン１のアーム４が伸展状態の場合では、ジョイント２は、図３に示すように、第１継手部８と第２継手部９とが連結状態になっている。 In this configuration, as shown in Figure 1, when the arm 4 of the drone 1 is extended, the joint 2 is connected to the first joint portion 8 and the second joint portion 9, as shown in Figure 3.
すなわち、図３および図９に示すように、第１継手部８の外嵌部４１に第２継手部９の内嵌部３１が内嵌し、外嵌部４１の内周面が第１Ｏリング３５と第２Ｏリング３６に圧接する。 That is, as shown in Figures 3 and 9, the inner fitting portion 31 of the second joint portion 9 is fitted into the outer fitting portion 41 of the first joint portion 8, and the inner circumferential surface of the outer fitting portion 41 is pressed against the first O-ring 35 and the second O-ring 36.
また、スライダ５１は、圧縮コイルばね５２の付勢力により第２継手方向へ付勢されていて、凸部６６が第２ヒンジ片６２の凹部６８に退避することによりスライダ５１の凸部５３がボール４３を押圧し、内嵌部３１の第２環状溝３３に圧接させる。 Furthermore, the slider 51 is biased toward the second joint by the biasing force of the compression coil spring 52. As the protrusion 66 retracts into the recess 68 of the second hinge piece 62, the protrusion 53 of the slider 51 presses against the ball 43, causing it to press against the second annular groove 33 of the inner fitting portion 31.
ボール４３は、内嵌部３１の第２環状溝３３を径方向内方に向けて押さえ付ける。 The ball 43 presses the second annular groove 33 of the inner fitting portion 31 radially inward.
これにより、内嵌部３１の外嵌部４１からの抜け止めが行われ、第１継手部８と第２継手部９との連結が強固に行われる。 This prevents the inner fitting portion 31 from coming loose from the outer fitting portion 41, and ensures a strong connection between the first joint portion 8 and the second joint portion 9.
このとき、ボール４３は、ヒンジ部１０の反対側に多く配置されているため、内嵌部３１の押え付けをより効果的に行うことができる。 In this case, since the balls 43 are positioned in large numbers on the opposite side of the hinge portion 10, the inner fitting portion 31 can be pressed more effectively.
また、このとき、第３Ｏリング５６はスライダ５１に覆われておらず露出しているため、第３Ｏリング５６を目視により確認することができ、これにより第１継手部８と第２継手部９とが連結状態であることが判る。 Furthermore, at this time, the third O-ring 56 is not covered by the slider 51 and is exposed, allowing for visual confirmation of the third O-ring 56. This confirms that the first joint 8 and the second joint 9 are connected.
また、このとき、第１Ｏリング３５は目視することができない。 Furthermore, at this time, the first O-ring 35 cannot be seen visually.
このアーム４の伸展状態から、図２に示すように、アーム４を折曲状態にする場合には、一対の取手５７を片手の手指で操作し、スライダ５１を圧縮コイルばね５２に抗してスライドさせると、スライダ５１の凸部５３がボール４３から離れスライダ５１の凹部５４にボール４３が退避する。 To fold the arm 4 from its extended state to the bent state shown in Figure 2, the pair of handles 57 are operated with the fingers of one hand, and the slider 51 is slid against the compression coil spring 52. This causes the convex portion 53 of the slider 51 to separate from the ball 43, and the ball 43 to retract into the concave portion 54 of the slider 51.
これにより、ボール４３の内嵌部３１への圧接が解除され、図５および図１１に示すように、第１継手部８と第２継手部９との連結が解除される。 This releases the pressure contact between the ball 43 and the inner fitting portion 31, and, as shown in Figures 5 and 11, the connection between the first joint portion 8 and the second joint portion 9 is released.
このとき、スライダ５１の凸部６６は第２ヒンジ片６２の凹部６８から離れ、第２ヒンジ片６２の周面部６７に当接するので、スライダ５１は第３Ｏリング５６を覆う状態となり、第３Ｏリング５６を目視により確認することができない。 At this time, the protrusion 66 of the slider 51 separates from the recess 68 of the second hinge piece 62 and contacts the circumferential surface 67 of the second hinge piece 62. Therefore, the slider 51 covers the third O-ring 56, making it impossible to visually confirm the third O-ring 56.
一方、第１Ｏリング３５は露出して目視により確認できるので、第１継手部８と第２継手部９との連結状態が解除されていることが判る。 On the other hand, since the first O-ring 35 is exposed and can be visually inspected, it can be seen that the connection between the first joint 8 and the second joint 9 has been released.
アーム４を折畳状態から伸展状態にする場合は、第１継手部８に対し第２継手部９を回動させ、第２継手部９の内嵌部３１を第１継手部８の外嵌部４１に内嵌するだけで、第１継手部８と第２継手部９とを連結することができる。 To extend the arm 4 from its folded state, the first joint 8 and the second joint 9 are connected simply by rotating the second joint 9 relative to the first joint 8 and fitting the inner fitting portion 31 of the second joint 9 into the outer fitting portion 41 of the first joint 8.
このとき、スライダ５１は、凸部６６が第２ヒンジ片６２の凹部６８に嵌入し、圧縮コイルばね５２の付勢力によりボール４３を押圧する状態に復帰する。 At this point, the slider 51 returns to a state where the protrusion 66 fits into the recess 68 of the second hinge piece 62, and the biasing force of the compression coil spring 52 presses against the ball 43.
以上の構成によれば、第１継手部８と第２継手部９との分離状態（折曲状態）では第１継手部８と第２継手部９とはヒンジ部１０のみで支持されているので、折曲角度の制限を可及的に無くすことができる。 With the above configuration, in the separated state (bent state) of the first joint 8 and the second joint 9, the first joint 8 and the second joint 9 are supported only by the hinge portion 10, thus minimizing the limitations on the bending angle.
しかも、第１継手部８と第２継手部９との連結状態（伸展状態）では、第１継手部８側のボール４３で第２継手部９側の内嵌部３１を押圧して挟持するようにしたので、第１継手部８と第２継手部９との連結強度を向上させることができる。 Furthermore, in the connected state (extended state) of the first joint 8 and the second joint 9, the ball 43 on the first joint 8 side presses against and clamps the inner fitting 31 on the second joint 9 side, thereby improving the connection strength between the first joint 8 and the second joint 9.
さらに、取手５７を片手で操作するだけで第１継手部８と第２継手部９との連結状態を解除でき、また第２継手部９を回動させることにより第１継手部８と第２継手部９とを連結することができるので、ジョイント２の第１継手部８と第２継手部９との連結と分離をワンタッチで行うことができる。 Furthermore, the connection between the first joint 8 and the second joint 9 can be released by simply operating the handle 57 with one hand, and the connection can be re-established by rotating the second joint 9. Therefore, the connection and disconnection of the first joint 8 and the second joint 9 of the joint 2 can be performed with a single touch.
すなわち、アーム４を折曲状態と伸展状態にすることが容易にできる。 In other words, it is easy to switch between the bent and extended states of arm 4.
しかも、連結状態では第３Ｏリング５６が露出し、連結解錠状態では第１Ｏリング３５が露出するので、連結状態か連結解除状態かを容易に把握することができる。 Furthermore, since the third O-ring 56 is exposed when the device is connected and the first O-ring 35 is exposed when the device is unlocked, it is easy to determine whether the device is connected or unlocked.
さらに、第１継手部８と第２継手部９を管状に形成したので、胴体３からプロペラ５の駆動部への配線などを収容することができる。 Furthermore, since the first joint section 8 and the second joint section 9 are formed in a tubular shape, wiring from the fuselage 3 to the propeller 5's drive unit can be accommodated.
