なお、接続管部用付勢部材３４は接続管部３２が自動的にほぼ垂直状態まで起き上がるように付勢するものであればどのようなものでもよく、捻りコイルバネ（捻りバネ）に限定されないが、狭い収納スペースに設けることができ、かつ強い付勢力が得られやすい上で捻りコイルバネが好適である。
また、接続管部用付勢部材３４は接続管部３２が起き上がるように付勢するものであるが、接続管部３２がほぼ垂直状態まで起き上がることに限らず、任意の角度に位置するようにしてもよい。この場合には、捻りコイルバネの付勢力を調整することで接続管部３２を任意の位置に留めることができる。例えば、身長が低い使用者の場合には、延長パイプ２０を吸込口体３０の接続管部３２に挿入する際に、接続管部３２が傾斜している方がほぼ垂直状態から挿入する場合より挿入しやすくなる。 The connecting pipe portion urging member 34 may be any member as long as it automatically urges the connecting tube portion 32 to rise to a substantially vertical state, and is not limited to a torsion coil spring (torsion spring). A torsion coil spring is preferable because it can be provided in a narrow storage space and a strong biasing force can be easily obtained.
Further, the connecting pipe portion urging member 34 urges the connecting pipe portion 32 to rise, but the connecting pipe portion 32 is not necessarily raised to a substantially vertical state, and is positioned at an arbitrary angle. May be. In this case, the connecting pipe portion 32 can be held at an arbitrary position by adjusting the biasing force of the torsion coil spring. For example, in the case of a user with a short height, when the extension pipe 20 is inserted into the connection pipe portion 32 of the suction port body 30, the inclined connection pipe portion 32 is inserted from a substantially vertical state.

In a state where the annular brush portion 22 configured in this manner is connected to the first connection portion 21b of the pipe body 21a, a pair of hole portions 21b 21 (see FIG. 5) communicating with the pair of clip-shaped terminals 21e 2 of the first connection portion 21b. 7), as shown in FIGS. 13A and 13B, the terminal portion cover 22d that is raised is covered from the outside.
Therefore, when cleaning the corners or the like of the floor surface in the extension pipe 30 after removing the suction port body 30 an annular brush 22, it flows air containing dust along the concave surface 22d 1 of the terminal cover 22d pipe for flowing into the main body 21a, a pair of clip-type dust terminal 21e 2 of the first connection portion 21b is prevented from adhering.

さらに、端子部カバー２２ｄの揺動片２２ｄ2が接続管部２２ａの凹曲面との間の隙間を塞いでいるため、この隙間にダストを含む空気が流入してダストが第１接続部２１ｂの一対のクリップ形端子２１ｅ2に付着することもない。
この結果、吸込口体３０を延長パイプ２０に接続したときに、延長パイプ２０側のクリップ形端子２１ｅ2と吸込口体３０側の端子部３２ｄとの接点不良といった故障を防止することができる。さらに、端子部３２ｄに接続管部２２ａが接触したり、端子部３２ｄに手が触れることを防止することができる。 Furthermore, since the swinging piece 22d 2 of the terminal cover 22d is closes the gap between the concave surface of the connecting tube portion 22a, the dust flows into the air containing dust to the gap of the first connecting portion 21b nor does it adhere to the pair of clip-type terminal 21e 2.
As a result, it is possible when connecting the suction port body 30 to the extension pipe 20, to prevent failure such as contact failure between the terminal portion 32d of the extension pipe 20 side clip type terminal 21e 2 and the suction port body 30 side. Furthermore, it is possible to prevent the connecting pipe portion 22a from coming into contact with the terminal portion 32d and the hand from touching the terminal portion 32d.

また、吸込口体３０を延長パイプ２０に接続する際、吸込口体３０の接続管部３２の先端小径部３２ｃ（図２参照）を環状ブラシ部２２に挿入していくと、先端小径部３２ｃが起き上がった端子部カバー２２ｄの凹曲面部２２ｄ1によってパイプ本体２１の第１接続部２１ｂの開口部へ案内される。そして、先端小径部３２ｃが第１接続部２１ｂ内に挿入されていくと、吸込口体３０の一対の端子部３２ｄおよび大径部３２ｂが端子部カバー２２ｄの凹曲面部２２ｄ1を押し、図１４（Ａ）および（Ｂ）に示すように、端子部カバー２２ｄは軸２２ｅを中心に揺動してパイプ本体２１と平行な状態まで倒れる。 Further, when the suction port body 30 is connected to the extension pipe 20, when the tip small diameter portion 32 c (see FIG. 2) of the connection pipe portion 32 of the suction port body 30 is inserted into the annular brush portion 22, the tip small diameter portion 32 c. It is guided into the opening of the first connection portion 21b of the pipe main body 21 from the concave curved surface portion 22 d 1 of got up a terminal cover 22d. When the front-end small-diameter portion 32c is gradually inserted into the first connection portion 21b, a pair of terminal portions 32d and the large diameter portion 32b of the suction port body 30 presses the concave surface portion 22 d 1 of the terminal cover 22 d, FIG. 14 (A) and 14 (B), the terminal cover 22d swings about the shaft 22e and falls to a state parallel to the pipe body 21.

これにより、パイプ本体２１側の一対のクリップ形端子２１ｅ2が外部に露出するため、吸込口体３０側の一対の端子部３２ｄがパイプ本体２１側の一対のクリップ形端子２１ｅ2内に挿入されて電気的に接続すると共に、吸込口体３０側の係止凹部３２ｃ1に延長パイプ２０側のロック機構部２１ｄの係止爪２１ｄ11が係止し、吸込口体３０の延長パイプ２０への接続が完了する。 As a result, the pair of clip-shaped terminals 21e 2 on the pipe body 21 side is exposed to the outside, so that the pair of terminal portions 32d on the suction port body 30 side is inserted into the pair of clip-shaped terminals 21e 2 on the pipe body 21 side. converting mechanism electrically connecting the engaging claw 21d 11 of the extension pipe 20 side of the lock mechanism portion 21d in the engagement recess 32c 1 of the suction port body 30 side is engaged, to extension pipe 20 of the suction port body 30 Connection is complete.

さらに詳しく説明すると、延長パイプ２０のロック機構部２１ｄの自由状態においては、図１１（Ａ）に示すように圧縮バネ２１ｄ2によってロック部材２１ｄ1の押しボタン２１ｄ12が外方へ押し出され、かつ係止爪２１ｄ11が第１接続部２１ｂの内部へ突出している。この状態の延長パイプ２０の第１接続部２１ｂ内に吸込口体３０の接続管部３２の先端小径部３２ｃを差し込むと、先端小径部３２ｃの係止凹部３２ｃ1にロック機構部２１ｄの係止爪２１ｄ11が係止し、延長パイプ２０に抜けないように吸込口体３０が接続され、吸込口体３０の一対の端子部３２ｄが延長パイプ２０の一対のクリップ形端子２１ｅ2内に挿入されて電気的に接続する。 In more detail, in a free state of the lock mechanism portion 21d of the extension pipe 20, the push button 21d 12 of the locking member 21d 1 is pushed outwardly by the compression spring 21d 2 as shown in FIG. 11 (A), and engaging claw 21d 11 protrudes into the interior of the first connecting portion 21b. When inserting the distal end small diameter portion 32c of the connecting tube portion 32 of the suction mouth 30 to the first connection portion 21b of the extension pipe 20 in this state, the locking of the lock mechanism portion 21d in the engagement recess 32c 1 of the front hole portion 32c The suction port body 30 is connected so that the claw 21 d 11 is locked and does not come out of the extension pipe 20, and the pair of terminal portions 32 d of the suction port body 30 are inserted into the pair of clip-shaped terminals 21 e 2 of the extension pipe 20. Connect them electrically.

このとき、吸込口体３０の一対の端子部３２ｄは接続管部３２ｃの裏面側に配置されているため、吸込口体３０と接続した延長パイプ２０のロック機構部２１ｄおよびロック解除操作機構部２１ｆの操作レバー２１ｆ3も裏面側に配置されることになる（図１参照）。
また、延長パイプ２０の他端部の接続管部２１ｃ3は、掃除機本体１０の駆動装置１１の接続管部１１ｅ内に差し込まれて接続され、これにより延長パイプ２０の接続管部２１ｃ3の係止凹部２１ｃ31に駆動装置１１の接続管部１１ｅに設けられた図示しないロック機構部の係止爪が係止してロックし、かつ延長パイプ２０の一対の棒形端子２１ｅ3が駆動装置１１の接続管部１１ｅ内に設けられた図示しない一対のクリップ形端子内に差し込まれて電気的に接続する。なお、駆動装置１１側のロック機構部は、延長パイプ２０側のロック機構部２１ｄと同様に構成されている。 At this time, since the pair of terminal portions 32d of the suction port body 30 are disposed on the back surface side of the connection pipe portion 32c, the lock mechanism portion 21d and the unlocking operation mechanism portion 21f of the extension pipe 20 connected to the suction port body 30. The operation lever 21f 3 is also arranged on the back side (see FIG. 1).
Further, the connecting pipe portion 21c 3 at the other end of the extension pipe 20 is inserted into and connected to the connecting pipe portion 11e of the driving device 11 of the cleaner body 10, and thereby the connecting pipe portion 21c 3 of the extension pipe 20 is connected. lock engagement claw engages the locking mechanism (not shown) provided in the locking recess 21c 31 to the connecting tube portion 11e of the drive unit 11, and a pair of bar-shaped terminal 21e 3 is drive extension pipe 20 11 are inserted into a pair of clip-shaped terminals (not shown) provided in the connecting pipe portion 11e to be electrically connected. Note that the lock mechanism portion on the drive device 11 side is configured in the same manner as the lock mechanism portion 21d on the extension pipe 20 side.

一方、ロック機構部２１ｄのロック部材２１ｄ1の押しボタン２１ｄ12を押すことにより、図１１（Ｂ）に示すように軸部２１ｄ13を中心にロック部材２１ｄ1が揺動し、係止爪２１ｄ11が第１接続部２１ｂ内から外方（矢印Ｃ方向）へ引っ込んで係止爪２１ｄ11が係止凹部３２ｃ1から離脱してロックが解除される。そのため、押しボタン２１ｄ12を押しながら延長パイプ２０と吸込口体３０とを互いに引き離すことにより、延長パイプ２０から吸込口体３０を取り外すことができる。 On the other hand, by pressing the push button 21d 12 of the locking member 21d 1 of the lock mechanism portion 21d, and the locking member 21d 1 about the shaft portion 21d 13 is swung as shown in FIG. 11 (B), the engaging claw 21d 11 engaging claw 21d 11 retracted outwardly (arrow C) the lock disengaged from the engagement recess 32c 1 is released from the first connecting portion 21b. Therefore, by separating the extension pipe 20 and the suction port body 30 together while pressing the push button 21d 12, can be removed suction port body 30 from the extension pipe 20.

さらに、本発明の電気掃除機１によれば、ロック解除操作機構部２１ｆの操作レバー２１ｆ3を矢印Ｂ方向（図１０参照）に引くことによってもロック機構部２１ｄのロックを解除することもできる。
この場合、操作レバー２１ｆ3を指で矢印Ｂ方向に引くと、図１１（Ｂ）に示すようにワイヤー２１ｆ1を介してスライド片２１ｆ2が矢印Ｂ方向に引っ張られ、スライド片２１ｆ2の左右一対の摺接爪２１ｆ21がロック部材２１ｄ1の左右一対の摺接片２１ｄ14の傾斜面に摺接しながら矢印Ｂ方向に移動する。これにより、左右一対の摺接片２１ｄ14と共に係止爪２１ｄ11が軸部２１ｄ13を中心に矢印Ｃ方向に揺動して第１接続部２１ｂ内から外方へ引っ込み、係止爪２１ｄ11が係止凹部３２ｃ1から離脱してロックが解除される。 Furthermore, according to the electric vacuum cleaner 1 of the present invention, it is also possible to unlock the lock mechanism portion 21d by pulling the operating lever 21f 3 of unlocking mechanism portion 21f in the direction of the arrow B (see FIG. 10) .
In this case, when pulling the operating lever 21f 3 in the arrow B direction by a finger, the slide piece 21f 2 via a wire 21f 1 as shown in FIG. 11 (B) is pulled in the direction of arrow B, the left and right slide piece 21f 2 a pair of sliding pawl 21f 21 is moved in the direction of arrow B while sliding on the inclined surfaces of the pair of left and right sliding piece 21d 14 of the locking member 21d 1. Thus, the engaging claw 21d 11 pair of right and left sliding piece 21d 14 is retracted from the first connection portion 21b swings in the direction of arrow C around the shaft portion 21d 13 outward, the engaging claw 21d 11 Is released from the locking recess 32c 1 and the lock is released.

そのため、使用者は立った姿勢で吸込口体３０の吸込口本体３１を踏んで床面Ｆに押さえ付け、操作レバー２１ｆ3を矢印Ｂ方向に引きながら延長パイプ２０を引っ張ることにより、使用者は腰を屈めることなく立ったままの楽な姿勢で延長パイプ２０から吸込口体３０を取り外すことができる。
なお、操作レバー２１ｆ3から指を離すと、付勢部材２１ｆ4によって第１接続部２１ｂの方へ付勢された操作レバー２１ｆ3、ワイヤー２１ｆ1およびスライド片２１ｆ2がロック部材２１ｄ1の軸部２１ｄ13側へスライドし、かつ圧縮バネ２１ｄ2によって付勢されたロック部材２１ｄ1が軸部２１ｄ13を中心に図１１（Ａ）に示す自由状態まで揺動する。 Therefore, the user steps on the suction port body 31 of the suction port body 30 and presses it against the floor surface F in a standing posture, and pulls the extension pipe 20 while pulling the operation lever 21f 3 in the direction of arrow B. The suction port body 30 can be removed from the extension pipe 20 in an easy posture while standing without bending the waist.
