従来、一般的な電気掃除機は、掃除機本体と、この掃除機本体に一端が接続されるホースと、ホースの他端に接続される手元操作部と、手元操作部に接続される管と、管の他端に着脱可能に取り付けられる吸込具とを備えて構成されている。
通常、管から吸込具を取り外す場合には、操作者が管と吸込具との両方を手に持ったり、これらを被清掃面に置いた状態でかがんだりして、管の一端に設けられた解除ボタンを押圧操作して管と吸込具との係合を解除し、管から吸込具を取り外していた。
Conventionally, a general electric vacuum cleaner has a vacuum cleaner body, a hose that is connected to the vacuum cleaner body, a hand operating part that is connected to the other end of the hose, and a pipe that is connected to the hand operating part. The suction tool is detachably attached to the other end of the tube.
Usually, when removing the suction tool from the pipe, the operator holds both the pipe and the suction tool in his hand, or bends them while they are placed on the surface to be cleaned. The release button is pressed to release the engagement between the pipe and the suction tool, and the suction tool is removed from the pipe.

一方、このような解除操作を行わずに、管と吸込具との係合を解除するようにした電気掃除機も知られている(例えば、特許文献1参照)。
この電気掃除機では、吸込具を床面に置いた状態で、管を略垂直に立てる操作を行うことで、管と吸込具との係合が解除されるように構成されている(例えば、特許文献1参照)。
On the other hand, a vacuum cleaner that releases the engagement between the pipe and the suction tool without performing such a release operation is also known (for example, see Patent Document 1).
This vacuum cleaner is configured to release the engagement between the pipe and the suction tool by performing an operation of standing the pipe substantially vertically with the suction tool placed on the floor (for example, Patent Document 1).

また、吸込具に操作ペダルを設けて、この操作ペダルを足で踏むことによって、管と吸込具との係合が解除されるようにしたものも知られている(例えば、特許文献2参照)。
このような電気掃除機によれば、前記のように操作者が管と吸込具とを手に持ったり、かがんだりして解除操作を行う必要がなくなり、解除操作が容易である。
In addition, there is also known one in which an operation pedal is provided in the suction tool and the engagement between the pipe and the suction tool is released by stepping on the operation pedal with a foot (for example, see Patent Document 2). .
According to such a vacuum cleaner, as described above, it is not necessary for the operator to perform the release operation by holding the tube and the suction tool or bending over, and the release operation is easy.

凹溝41eと収容室S1とは、後記するように、スライド部材41の係止部41cが第1の位置(図3、図5(a)に示す位置)にあるときに、相互に連通する位置関係となるように設けられている。これによって、基準面F(図4参照)と延長管5(図1参照)の軸心O1とのなす角度θが90度以上となるように、第1の継手20および第2の継手30を起立させると、凹溝41eにある球状部材46が重力によって収容室S1へと転動するようになっている(図7(a)(b)参照)。球状部材46の形状は、球形状に限らず、凹溝41eから収容室S1へ容易に移動可能な形状であれば、楕円形状、円柱形状、角形状であってもよい。   As will be described later, the concave groove 41e and the storage chamber S1 communicate with each other when the locking portion 41c of the slide member 41 is in the first position (the position shown in FIGS. 3 and 5A). It is provided so as to be in a positional relationship. Accordingly, the first joint 20 and the second joint 30 are made so that the angle θ formed by the reference plane F (see FIG. 4) and the axis O1 of the extension pipe 5 (see FIG. 1) is 90 degrees or more. When standing, the spherical member 46 in the concave groove 41e rolls into the accommodation chamber S1 by gravity (see FIGS. 7A and 7B). The shape of the spherical member 46 is not limited to a spherical shape, and may be an elliptical shape, a cylindrical shape, or a square shape as long as it can be easily moved from the concave groove 41e to the storage chamber S1.

また、凹溝41eは、後記するように、スライド部材41の係止部41cが第2の位置(図5(b)参照)にあるときに、収容室S1よりも後方にスライド移動して、カバー部材32の後方に位置するようになっている。
前壁部41b2は、延設部41b1の前部に一体的に設けられており、基体31に設けられた縦壁31a(図3参照)に沿ってスライド移動可能となっている。ここで、縦壁31aの後端部31bは、後方へ向けて下り傾斜状とされており、図5(b)に示すように、スライド部材41の係止部41cが第2の位置にスライド(最後端へスライド)した場合においても、前壁部41b2が、後端部31bに係合するように構成されている。
これによって、スライド部材41のスムーズなスライドが実現されるようになっている。なお、後端部31bには、延設部41b1の前部の傾斜面41fが係合するようになっている(図3参照)。
Further, as will be described later, when the locking portion 41c of the slide member 41 is in the second position (see FIG. 5B), the concave groove 41e slides backward from the storage chamber S1, It is located behind the cover member 32.
The front wall portion 41b2 is provided integrally with the front portion of the extending portion 41b1, and is slidable along a vertical wall 31a (see FIG. 3) provided on the base 31. Here, the rear end portion 31b of the vertical wall 31a is inclined downward toward the rear, and as shown in FIG. 5B, the locking portion 41c of the slide member 41 slides to the second position. Even in the case of (slide to the rear end), the front wall portion 41b2 is configured to engage with the rear end portion 31b.
As a result, smooth sliding of the slide member 41 is realized. In addition, the inclined surface 41f of the front part of the extension part 41b1 engages with the rear-end part 31b (refer FIG. 3).

本実施形態では、後記するように、凹溝41e内から収容室S1内に球状部材46が転動することで(第1の継手20と第2の継手30とを起立させて解除位置に球状部材46を転動させることで)、スライド部材41のロック状態が解除されるようになっており(図7(a)(b)参照)、スライド部材41の後方へのスライドが可能となっている。
一方、図3に示すように、凹溝41e内に球状部材46が位置する場合(保持位置にある場合)には、球状部材46が図5(a)に示す後壁部39bの側壁39cに当接して、スライド部材41の後方へのスライドを邪魔するようになっている。これによって、スライド部材41の後方へのスライドがロック状態とされる。
In the present embodiment, as will be described later, the spherical member 46 rolls from the concave groove 41e into the accommodation chamber S1 (the first joint 20 and the second joint 30 are raised and spherical at the release position. The sliding state of the slide member 41 is released (by rolling the member 46) (see FIGS. 7A and 7B), and the slide member 41 can be slid backward. Yes.
On the other hand, as shown in FIG. 3, when the spherical member 46 is positioned in the concave groove 41e (when in the holding position), the spherical member 46 is placed on the side wall 39c of the rear wall portion 39b shown in FIG. It abuts against the sliding of the slide member 41 to the rear. As a result, the backward sliding of the slide member 41 is brought into a locked state.

前壁部41b2と後壁部39bとの間には、スライド部材41を第2の位置から第1の位置へ向けて付勢する付勢手段としての一対のコイルばね38が縮設されている。   Between the front wall portion 41b2 and the rear wall portion 39b, a pair of coil springs 38 serving as urging means for urging the slide member 41 from the second position toward the first position is contracted. .

カバー部材32の後端部には、延長管5の軸方向(筒状接続部33の軸方向)に延びる一対の電源端子37、37が突設されている。この電源端子37、37は、第2の吸込具6の前端部に設けられた図示しない接続部に対応して設けられており、第2の継手30に対して第2の吸込具6を差し込まれて接続されると、図示しない接続部に電気的に接続されるようになっている。電源端子37、37は、2本ではなく、3本であってもよい。   At the rear end portion of the cover member 32, a pair of power supply terminals 37, 37 extending in the axial direction of the extension pipe 5 (the axial direction of the cylindrical connecting portion 33) are provided. The power supply terminals 37, 37 are provided corresponding to connection portions (not shown) provided at the front end portion of the second suction tool 6, and the second suction tool 6 is inserted into the second joint 30. Once connected, they are electrically connected to a connection portion (not shown). The power supply terminals 37 and 37 may be three instead of two.

枠部材42は、図2、図5(a)に示すように、延長管5(筒状接続部33)の軸方向に沿う一対の第1の面44、44を有するとともに、後端部に切欠部45、45を有する。一対の第1の面44、44間には、スライド部材41の係止部41cが軸方向にスライド可能に配置される。また、切欠部45、45は、第2の吸込具6の係合部材6aの周方向の移動を許容する大きさを有しており、係止部41cが図5(b)に示す第2の位置にあるときに、係合部材6aは、第2の面41dから切欠部45を通ることで係合部40から離脱可能となっている。   As shown in FIGS. 2 and 5A, the frame member 42 has a pair of first surfaces 44, 44 along the axial direction of the extension pipe 5 (cylindrical connecting portion 33), and at the rear end portion. Notches 45 and 45 are provided. Between the pair of first surfaces 44, 44, a locking portion 41c of the slide member 41 is disposed so as to be slidable in the axial direction. The notches 45, 45 have a size that allows the engagement member 6a of the second suction tool 6 to move in the circumferential direction, and the locking portion 41c is the second shown in FIG. 5B. The engaging member 6a can be detached from the engaging portion 40 by passing through the notch 45 from the second surface 41d.

ここで、図3に示すように、第2の吸込具6に設けられたフック状の係合部材6aは、図示しない付勢部材によって、係合部40に向けて突出する側に付勢されており、この付勢によって、スライド部材41の係止部41cの第2の面41dに係止されるようになっている。
なお、係合部材6aは、第2の吸込具6の上面に設けられたボタン6bを押圧操作することによって、前記付勢力に抗して係止状態を解除することが可能である。
Here, as shown in FIG. 3, the hook-shaped engaging member 6 a provided in the second suction tool 6 is urged toward the side protruding toward the engaging portion 40 by an urging member (not shown). By this urging, it is locked to the second surface 41d of the locking portion 41c of the slide member 41.
The engaging member 6a can release the locked state against the urging force by pressing the button 6b provided on the upper surface of the second suction tool 6.

次に、第1の吸込具10の第2の継手30と第2の吸込具6との係脱操作について説明する。
第2の継手30に第2の吸込具6を接続する際には、第2の継手30の筒状接続部33に第2の吸込具6を差し込んで、第2の継手30の係合部40に第2の吸込具6の係合部材6aを係合させる。
このとき、筒状接続部33に第2の吸込具6を差し込んでいくと、係合部材6aが、スライド部材41の係止部41cを乗り越え、付勢力によって係止部41cの第2の面41dに係止される。これによって、第2の継手30に第2の吸込具6を接続することができる。
Next, the engagement / disengagement operation between the second joint 30 of the first suction tool 10 and the second suction tool 6 will be described.
When connecting the second suction tool 6 to the second joint 30, the second suction tool 6 is inserted into the cylindrical connection portion 33 of the second joint 30, and the engaging portion of the second joint 30 is inserted. The engaging member 6 a of the second suction tool 6 is engaged with 40.
At this time, when the second suction tool 6 is inserted into the cylindrical connecting portion 33, the engaging member 6a gets over the locking portion 41c of the slide member 41, and the second surface of the locking portion 41c by the biasing force. It is locked to 41d. Thereby, the second suction tool 6 can be connected to the second joint 30.

ここで、接続時には、係止部41cが第1の位置にあり、凹溝41eと収容室S1は連通しているので、前記のように第1の継手20および第2の継手30を起立させなければ、球状部材46は、重力によって凹溝41e内に位置している。
これによって、図5(a)に示すように、球状部材46が後壁部39bの側壁39cに当接して、スライド部材41の後方へのスライドを邪魔し、スライド部材41は、第1の位置にスライド不能にロックされることとなる。
したがって、使用時に、操作管4(図1参照、以下同じ)を手で把持して延長管5を引いたり押したりする操作を加えても、スライド部材41のロック状態が好適に維持されるようになり、スライド部材41の係止部41cから係合部材6aが外れることがない。
Here, at the time of connection, the locking portion 41c is in the first position, and the concave groove 41e and the storage chamber S1 communicate with each other, so that the first joint 20 and the second joint 30 are raised as described above. Otherwise, the spherical member 46 is located in the concave groove 41e by gravity.
As a result, as shown in FIG. 5A, the spherical member 46 abuts against the side wall 39c of the rear wall portion 39b to obstruct the slide of the slide member 41 to the rear, and the slide member 41 is moved to the first position. It will be locked so that it cannot slide.
Therefore, the locked state of the slide member 41 can be suitably maintained even when an operation of pulling or pushing the extension tube 5 by gripping the operation tube 4 (see FIG. 1, the same applies hereinafter) by hand during use. Thus, the engagement member 6a is not detached from the locking portion 41c of the slide member 41.

次に、第1の吸込具10と第2の吸込具6との接続を解除する場合について説明する。
はじめに、図6(a)(b)、図9(a)に示すように、第1の継手20および第2の継手30を起立させる。そして、図4に示すように、基準面Fと延長管5(図1参照)の軸心O1とのなす角度θが90度以上となるようにすると、図6(a)(b)に示すように、凹溝41e(保持位置)に位置していた球状部材46が、図7(a)(b)に示すように、収容室S1側(解除位置側)に転動する。これによって、球状部材46によるスライド部材41のスライドのロックが解除され、スライド部材41の位置変更が可能となる。
Next, the case where the connection between the first suction tool 10 and the second suction tool 6 is released will be described.
First, as shown in FIGS. 6A, 6B, and 9A, the first joint 20 and the second joint 30 are erected. Then, as shown in FIG. 4, when the angle θ between the reference plane F and the axis O1 of the extension pipe 5 (see FIG. 1) is 90 degrees or more, it is shown in FIGS. 6 (a) and 6 (b). As described above, the spherical member 46 located in the concave groove 41e (holding position) rolls toward the accommodation chamber S1 side (release position side) as shown in FIGS. As a result, the slide member 41 is unlocked by the spherical member 46 and the position of the slide member 41 can be changed.

そして、図9(b)に示すように、操作管4(図1参照)を手で把持しつつ、第1の吸込具10を足で抑える等して延長管5を上方向(矢印A1方向)に引き上げる操作を行うと、図8(a)(b)に示すように、スライド部材41が係合部材6aに引っ張られて上方向(矢印A1方向)にスライド移動し、第2の位置に移動する。   Then, as shown in FIG. 9B, while holding the operation tube 4 (see FIG. 1) by hand, the extension tube 5 is moved upward (in the direction of arrow A1) by holding the first suction tool 10 with a foot. 8), the slide member 41 is pulled by the engagement member 6a and slid upward in the direction of the arrow A1, as shown in FIGS. 8A and 8B. Moving.

この状態で、手で把持している操作管4に、図9(c)に示すような矢印B1方向のひねり操作を加える。そうすると、係止部41cの第2の面41dに当接していた係合部材6aが切欠部45を通じて係合部40から離脱し(図8(a)参照)、係合部40に対する係合部材6aの係合が解除される。
つまり、第1の吸込具10と第2の吸込具6のうち、一方が他方に対して延長管5の軸方向の引っ張り力および延長管5の軸心を基準とした軸心周りのねじり力が作用した場合に、係合部40に対する係合部材6aの係合が解除されることとなる。
In this state, a twisting operation in the direction of arrow B1 as shown in FIG. 9C is applied to the operating tube 4 held by hand. Then, the engaging member 6a that has been in contact with the second surface 41d of the locking part 41c is detached from the engaging part 40 through the notch part 45 (see FIG. 8A), and the engaging member for the engaging part 40 The engagement of 6a is released.
That is, of the first suction tool 10 and the second suction tool 6, one is the tensile force in the axial direction of the extension tube 5 with respect to the other and the twisting force around the axis centered on the axis of the extension tube 5. When is acted, the engagement of the engagement member 6a with the engagement portion 40 is released.

これによって、第1の吸込具10と第2の吸込具6との接続のロックを解除して、これらを容易に取り外すことができる。   Thereby, the lock | rock of the connection of the 1st suction tool 10 and the 2nd suction tool 6 is cancelled | released, and these can be removed easily.

以下では、本実施形態において得られる効果を説明する。
(1)使用者による操作管4への引っ張り操作およびひねり操作に応じて、第1の吸込具10が第2の吸込具6から外れる構成であるので、2つの異なる操作を行ったときにはじめて、第1の吸込具10を第2の吸込具6から切り離すことができる。つまり、引っ張り操作のみ、あるいはひねり操作のみでは、第1の吸込具10が第2の吸込具6から切り離されないので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。
(2)使用者による操作管4への引っ張り操作およびひねり操作に加え、被清掃面と延長管5(筒状接続部33)とのなす角度が略90度以上となる操作に応じて、第1の吸込具10が第2の吸込具6から外れるので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのをより一層確実に防止することができ、使い勝手の良い電気掃除機1が得られる。
(3)使用者による操作管4へのボタン4bの押下操作に応じて、延長管5が操作管4から外れ、使用者による延長管5へのボタン5bの押下操作に応じて、第2の吸込具6が延長管5から外れ、使用者による操作管4への引っ張り操作およびひねり操作以外に、使用者による第2の吸込具6へのボタン押下操作によっても、第2の吸込具6から第1の吸込具10が外れるので、各部を確実に取り外すことが可能であり、使い勝手のよい電気掃除機1が得られる。
(4)第1の吸込具10と第2の吸込具6のうち、一方が他方に対して延長管5の軸方向の引っ張り力および延長管5の軸心を基準とした軸心周りのねじり力が作用した場合にこれらが外れるようになっているので、2つの異なる方向の力が作用した場合にはじめて第2の吸込具6から第1の吸込具10を切り離すことができる。つまり、引っ張り力のみ、あるいはねじり力のみでは、第1の吸込具10が第2の吸込具6から切り離されないので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。
また、例えば、図4に示すように、基準面Fと延長管5(図1参照)の軸心O1とのなす角度θが90度以上となるように第1の継手20および第2の継手30を起立させる方向の力が作用したときに、スライド部材41のロック(接続のロック)を解除することができるので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。
(5)2以上の異なる方向の力は、延長管5の軸方向の力と延長管5の円周方向の力を含むので、力の方向が明確であり、操作が行い易いという利点が得られる。なお、切り離しに必要な力としては、前記のように第2の継手30を起立させる方向の力や、延長管5の軸心を基準とした軸心周りのねじり力を作用させて後に、延長管5を上方に引き抜く力等がある。
(6)ロック手段は、延長管5の軸方向の力が作用した後に、延長管5の円周方向の力が作用した場合に、接続のロックを解除するように構成されているので、接続のロックを解除するにあたって電源端子37の接続の解除を一連の操作の中で確実にしかも簡単に行うことができる。
(7)第1の位置に係合部材6aが位置するときに、電源端子37が第2の吸込具の接続部に接続され、第2の位置に係合部材6aが位置するときに、電源端子37と接続部との接続が解除されるように構成されているので、接続あるいは解除時に、電源端子37が破損するのを好適に阻止することができる。
(8)係合部40と、係合部40に係合可能な係合部材6aと、による簡単な構造で係脱を行うことができるので、組み付けが簡単になりコストの低減を図ることができる。
(9)スライド部材41は、第1の位置と第2の位置との間でスライド可能に設けられているので、スライド部材41のロック(接続のロック)を解除する構造が簡単になり、組み付けも簡単になってコストの低減を図ることができる。
(10)スライド部材41はコイルばね38によって、第2の位置から第1の位置に向けて付勢されているので、接続の解除後は、スライド部材41が第1の位置に自動的に復帰することとなり、接続時の誤動作等が生じにくいという利点が得られる。
(11)回動軸部21aの端部の切込部21bに、垂直位置決め手段9の摺動部材9aが係合するようになっているので、被清掃面に対して第1の継手20および第2の継手30が垂直に立ち上がる状態で保持することができる。したがって、第2の継手30に対する第2の吸込具6や延長管5等の着脱が容易であるという利点が得られる。
(12)基準面Fと延長管5(図1参照)の軸心O1とのなす角度θが90度以上となった場合にロック(接続のロック)を解除する機構(ロック解除機構)として、特許文献1では軸方向に延びるピンDを用いるのに対して、本実施例では、球状部材46を用いるため、ロック解除機構が第2の継手30上で完結しカバー部材22および基体21に形成されないので、カバー部材22と基体21の上面との間の空間部Kを広くできる。よって、空間部Kにハーネスだけでなく制御回路なども設けることができ、制御回路によって制御される複数の発光体(例えば、LED)をカバー部材22に設けることもできる。この複数の発光体は、第1の吸込具10の吸込口10aに形成される回転ブラシにかかる被清掃面からの負荷に応じてまたは掃除機本体2の運転モード(例えば、強、中、弱)に応じて変色(例えば、青、黄、緑)するのが好ましい。使用者による操作管4への引っ張り操作およびひねり操作がなく、被清掃面と延長管5(筒状接続部33)とのなす角度が略90度以上となる操作に応じて、第1の吸込具10が第2の吸込具6から外れる態様でもよい。
Below, the effect acquired in this embodiment is demonstrated.
(1) Since the first suction tool 10 is detached from the second suction tool 6 in response to a pulling operation and a twisting operation on the operation tube 4 by the user, the first time when two different operations are performed. The first suction tool 10 can be separated from the second suction tool 6. That is, since the first suction tool 10 is not separated from the second suction tool 6 only by the pulling operation or the twisting operation, the first suction tool 10 is unexpectedly removed from the second suction tool 6 during cleaning. It is possible to reliably prevent the disconnection, and the user-friendly vacuum cleaner 1 can be obtained.
(2) In addition to the pulling operation and the twisting operation to the operation tube 4 by the user, the operation of the angle between the surface to be cleaned and the extension tube 5 (cylindrical connecting portion 33) becomes approximately 90 degrees or more Since the 1 suction tool 10 comes off from the 2nd suction tool 6, it can prevent more reliably that the 1st suction tool 10 will come off from the 2nd suction tool 6 unexpectedly during cleaning, An easy-to-use vacuum cleaner 1 is obtained.
(3) The extension tube 5 is detached from the operation tube 4 in response to the pressing operation of the button 4b on the operation tube 4 by the user, and the second operation is performed in response to the pressing operation of the button 5b on the extension tube 5 by the user. The suction tool 6 is detached from the extension pipe 5, and in addition to the user's pulling operation and twisting operation on the operation pipe 4, the user can press the second suction tool 6 to press the second suction tool 6. Since the 1st suction tool 10 remove | deviates, it is possible to remove each part reliably and the user-friendly vacuum cleaner 1 is obtained.
(4) One of the first suction tool 10 and the second suction tool 6 is twisted around the axis centered on the basis of the pulling force in the axial direction of the extension pipe 5 and the axis of the extension pipe 5 with respect to the other. Since these are detached when a force is applied, the first suction device 10 can be separated from the second suction device 6 only when forces in two different directions are applied. That is, since the first suction tool 10 is not separated from the second suction tool 6 only by the pulling force or the torsional force, the first suction tool 10 is unexpectedly removed from the second suction tool 6 during cleaning. It is possible to reliably prevent the disconnection, and the user-friendly vacuum cleaner 1 can be obtained.
Further, for example, as shown in FIG. 4, the first joint 20 and the second joint so that the angle θ formed by the reference plane F and the axis O1 of the extension pipe 5 (see FIG. 1) is 90 degrees or more. When the force in the direction to erect 30 is applied, the slide member 41 can be unlocked (connection lock), so that the first suction tool 10 is unexpectedly moved from the second suction tool 6 during cleaning. It is possible to reliably prevent the disconnection, and the user-friendly vacuum cleaner 1 can be obtained.
(5) Since the forces in two or more different directions include the axial force of the extension tube 5 and the circumferential force of the extension tube 5, the advantage is that the direction of the force is clear and the operation is easy. It is done. In addition, as a force required for the separation, the force in the direction in which the second joint 30 is erected as described above or the torsional force around the axis centered on the axis of the extension pipe 5 is applied and then extended. There is a force for pulling the tube 5 upward.
(6) The locking means is configured to release the connection lock when the circumferential force of the extension pipe 5 is applied after the axial force of the extension pipe 5 is applied. In releasing the lock, the connection of the power terminal 37 can be reliably and easily performed in a series of operations.
(7) When the engaging member 6a is located at the first position, the power terminal 37 is connected to the connecting portion of the second suction tool, and when the engaging member 6a is located at the second position, the power source Since the connection between the terminal 37 and the connection portion is released, it is possible to suitably prevent the power supply terminal 37 from being damaged at the time of connection or release.
(8) Since the engagement portion 40 and the engagement member 6a engageable with the engagement portion 40 can be engaged and disengaged with a simple structure, the assembly is simplified and the cost can be reduced. it can.
(9) Since the slide member 41 is slidably provided between the first position and the second position, the structure for releasing the lock (connection lock) of the slide member 41 is simplified and assembled. The cost can also be reduced.
(10) Since the slide member 41 is biased by the coil spring 38 from the second position toward the first position, the slide member 41 automatically returns to the first position after the connection is released. Therefore, there is an advantage that malfunction or the like at the time of connection hardly occurs.
(11) Since the sliding member 9a of the vertical positioning means 9 is engaged with the notch 21b at the end of the rotating shaft 21a, the first joint 20 and the surface to be cleaned are The second joint 30 can be held in a state of rising vertically. Therefore, an advantage that the second suction tool 6 and the extension pipe 5 are easily attached to and detached from the second joint 30 can be obtained.
(12) As a mechanism (lock release mechanism) for releasing the lock (lock of connection) when the angle θ formed by the reference plane F and the axis O1 of the extension pipe 5 (see FIG. 1) is 90 degrees or more, In Patent Document 1, the pin D extending in the axial direction is used, but in this embodiment, since the spherical member 46 is used, the lock release mechanism is completed on the second joint 30 and formed on the cover member 22 and the base body 21. Since this is not done, the space K between the cover member 22 and the upper surface of the base 21 can be widened. Therefore, not only a harness but also a control circuit can be provided in the space K, and a plurality of light emitters (for example, LEDs) controlled by the control circuit can be provided in the cover member 22. The plurality of light emitters are operated according to the load from the surface to be cleaned applied to the rotary brush formed at the suction port 10a of the first suction tool 10 or the operation mode (for example, strong, medium, weak) of the cleaner body 2. ) Is preferably changed (for example, blue, yellow, green). The first suction is performed in response to an operation in which the user does not pull or twist the operation tube 4 and the angle between the surface to be cleaned and the extension tube 5 (cylindrical connecting portion 33) becomes approximately 90 degrees or more. The aspect which the tool 10 remove | deviates from the 2nd suction tool 6 may be sufficient.

なお、図10に示すように、第1の吸込具10に対して、第2の吸込具6だけではなく、延長管5や操作管4を接続することができ、またこれらを、前記と同様の操作を行うことによって切り離すことができる。したがって、清掃中に不意に延長管5や操作管4から第1の吸込具10が外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。また、係合部材6aは、従来のボタン6bの操作による構造をそのまま採用することができ、部品の共通化や組み付け作業の容易化を図ることができ、コストの低減を図ることができる。なお、図中係合部材6aは、係合部材5a、4aと対応しており、ボタン6bは、ボタン5b、4bに対応している。   As shown in FIG. 10, not only the second suction tool 6 but also the extension pipe 5 and the operation pipe 4 can be connected to the first suction tool 10, and these are the same as described above. It can be separated by performing the operation. Therefore, it is possible to reliably prevent the first suction tool 10 from being unexpectedly detached from the extension pipe 5 and the operation pipe 4 during cleaning, and the user-friendly vacuum cleaner 1 can be obtained. In addition, the engaging member 6a can adopt the structure by the operation of the conventional button 6b as it is, so that the parts can be shared and the assembling work can be facilitated, and the cost can be reduced. In the drawing, the engaging member 6a corresponds to the engaging members 5a and 4a, and the button 6b corresponds to the buttons 5b and 4b.

なお、第1の面44、44は、筒状接続部33に凹部を形成することで設けたが、これに限られることはなく、筒状接続部33にリブ等を設けて、その側面等で第1の面44、44を形成してもよい。また、切欠部45は、第1の面44、44の一方にのみ設けても良い。   The first surfaces 44 and 44 are provided by forming a concave portion in the cylindrical connecting portion 33, but the present invention is not limited to this, and a rib or the like is provided in the cylindrical connecting portion 33 so that the side surfaces thereof are provided. The first surfaces 44 and 44 may be formed. Further, the notch 45 may be provided only on one of the first surfaces 44 and 44.

(第2実施形態)
図11(a)(b)に示すように、本実施形態が前記第1実施形態と異なるところは、摺動部材35Aにロック機能を設けた点にある。
摺動部材35Aは、同図に示すように、後部に延びる延設部35bを備え、この延設部35bの後部に収容室S1に出没する解除規制部材35aが一体的に設けられている。
(Second Embodiment)
As shown in FIGS. 11A and 11B, the present embodiment is different from the first embodiment in that a locking function is provided on the sliding member 35A.
As shown in the figure, the sliding member 35A includes an extending portion 35b extending to the rear portion, and a release restricting member 35a that protrudes and retracts into the storage chamber S1 is integrally provided at the rear portion of the extending portion 35b.

解除規制部材35aは、図11(a)に示すように、カバー部材22の側面22aに摺動部材35Aの先端が当接している状態では、図11(b)に示すように、後端部35a1が収容室S1内に突出している。これによって、球状部材46が収容室S1側に転動することが規制されるようになっている。   As shown in FIG. 11 (a), the release regulating member 35a has a rear end portion as shown in FIG. 11 (b) in a state where the tip of the sliding member 35A is in contact with the side surface 22a of the cover member 22. 35a1 protrudes into the storage chamber S1. As a result, the spherical member 46 is restricted from rolling toward the storage chamber S1.

一方、図12(a)(b)に示すように、第1の継手20および第2の継手30Aが起立され、カバー部材22に設けられた凹状部24に摺動部材35Aが係合している状態では、収容室S1内から後端部35a1が没し、球状部材46の収容室S1への転動が可能となる。したがって、起立されると球状部材46は、凹溝41eから収容室S1に転動して、スライド部材41のロックが解除されるようになる。   On the other hand, as shown in FIGS. 12A and 12B, the first joint 20 and the second joint 30 </ b> A are erected, and the sliding member 35 </ b> A is engaged with the concave portion 24 provided in the cover member 22. In this state, the rear end portion 35a1 is sunk from the inside of the storage chamber S1, and the spherical member 46 can roll to the storage chamber S1. Therefore, when standing, the spherical member 46 rolls from the recessed groove 41e to the accommodation chamber S1, and the lock of the slide member 41 is released.

このような構成を備えることによって、図13(a)(b)に示すように、第1の継手20および第2の継手30Aが垂直方向に起立した姿勢を採るときにのみ、接続の解除が可能となる。
これにより、例えば、図14に示すように第1の継手20のみを起立するような姿勢で使用した場合に、矢印A1、B1方向への移動が不可となり、球状部材46の転動が確実に防止されるようになる。したがって、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。
By providing such a configuration, as shown in FIGS. 13 (a) and 13 (b), the connection can be released only when the first joint 20 and the second joint 30A take an upright posture. It becomes possible.
Accordingly, for example, when only the first joint 20 is used as shown in FIG. 14, the movement in the directions of the arrows A1 and B1 becomes impossible, and the rolling of the spherical member 46 is ensured. Will be prevented. Therefore, it is possible to reliably prevent the first suction tool 10 from being accidentally detached from the second suction tool 6 during cleaning, and the user-friendly vacuum cleaner 1 can be obtained.

なお、前記各実施形態において、第1の継手20や第2の継手30等を起立する際には、図15に示すように壁W等を利用して(壁Wに突き当てるようにして)容易に行うことができる。   In each of the above embodiments, when the first joint 20 or the second joint 30 is erected, the wall W or the like is used as shown in FIG. 15 (so as to abut against the wall W). It can be done easily.

(第3実施形態)
本実施形態が前記第1、第2実施形態と異なるところは、被清掃面と延長管5(図1参照、以下同じ)とのなす角度θ(図18(b)参照)が略60度以上となる操作で第1の吸込具10が第2の吸込具6(ともに図1参照、以下同じ)から外れるように構成した点にある。
(Third embodiment)
This embodiment differs from the first and second embodiments in that the angle θ (see FIG. 18B) formed by the surface to be cleaned and the extension pipe 5 (see FIG. 1, the same applies hereinafter) is approximately 60 degrees or more. It is the point which comprised so that the 1st suction tool 10 may remove | deviate from the 2nd suction tool 6 (both refer FIG. 1, and the following is the same) by operation which becomes.

図16に示すように、本実施形態では、ロック手段を構成する移動部材としての球状部材46が、傾斜部(傾斜面)としての前側傾斜部52を有する凹溝50に収容されるように構成されている。本実施形態においても、球状部材46は、凹溝50に収容されて第1の吸込具10と第2の吸込具6(延長管5)との接続のロックを保持する保持位置を採り、また、凹溝50に対応するカバー部材32の内面に形成された収容室S2に転動して、ロックを解除する解除位置を採るように構成されている。   As shown in FIG. 16, in this embodiment, the spherical member 46 as a moving member constituting the locking means is configured to be accommodated in a concave groove 50 having a front inclined portion 52 as an inclined portion (inclined surface). Has been. Also in this embodiment, the spherical member 46 is accommodated in the concave groove 50 and takes a holding position that holds the lock of the connection between the first suction tool 10 and the second suction tool 6 (extension pipe 5). The release position for releasing the lock is configured by rolling into the storage chamber S2 formed on the inner surface of the cover member 32 corresponding to the concave groove 50.

凹溝50は、図17に示すように、スライド部材41のガイド部41bの延設部41b1に、側面視で略すり鉢形状に形成されており、底面部51と、傾斜部としての前側傾斜部52と、後側傾斜部53とを備えてなる。底面部51は、延長管5の軸心O1(図4参照、以下同じ)と平行に設けられており、また、前側傾斜部52は、底面部51との角度θ1が鈍角となるように底面部51から前側へ向けて傾斜するように形成されている。本実施形態では、角度θ1を120度に設定している。
つまり、図示しない被清掃面に対向する第1の吸込具10の吸込口面を基準面Fとしたときに、基準面Fと延長管5の軸心O1(またはこれに平行な線O1’)とのなす角度が60度になると、前側傾斜部52は、基準面Fと平行になるように設定されている(図18(b)参照、)。
なお、前側傾斜部52は、収容室S2へ向けた直線状の傾斜面としたが、これに限られることはなく、前側へ向けて凹状とされた斜面を有するように形成したものでもよく、また、これとは逆に後側へむけて凸状とされた斜面を有するように形成したものでもよい。また、底面部51は、延長管5の軸心O1と必ずしも平行に設ける必要はない。
As shown in FIG. 17, the concave groove 50 is formed in a substantially mortar shape in the extended portion 41 b 1 of the guide portion 41 b of the slide member 41 in a side view, and includes a bottom surface portion 51 and a front inclined portion as an inclined portion. 52 and a rear inclined portion 53. The bottom surface portion 51 is provided in parallel with the axis O1 (see FIG. 4; hereinafter the same) of the extension pipe 5, and the front inclined portion 52 has a bottom surface so that the angle θ1 with the bottom surface portion 51 becomes an obtuse angle. It is formed so as to incline from the portion 51 toward the front side. In the present embodiment, the angle θ1 is set to 120 degrees.
That is, when the suction port surface of the first suction tool 10 that opposes the surface to be cleaned (not shown) is the reference surface F, the reference surface F and the axis O1 of the extension pipe 5 (or a line O1 ′ parallel thereto). When the angle between the front inclined portion 52 and the reference plane F is set to 60 degrees (see FIG. 18B).
The front inclined portion 52 is a linear inclined surface toward the storage chamber S2, but is not limited thereto, and may be formed to have a slope that is concave toward the front side. On the contrary, it may be formed so as to have a slope that is convex toward the rear side. Further, the bottom surface portion 51 is not necessarily provided in parallel with the axis O1 of the extension pipe 5.

このような前側傾斜部52を備えることによって、球状部材46は、前記第1実施形態のところで図4を参照して説明したような、基準面Fと延長管5の軸心O1とのなす角度θが90度以上となる前の段階、すなわち、角度θが60度以上となるようにする操作で、第1の吸込具10が第2の吸込具6(延長管5)から外れるようになっている。   By providing such a front inclined portion 52, the spherical member 46 has an angle formed by the reference plane F and the axis O1 of the extension tube 5 as described with reference to FIG. 4 in the first embodiment. The first suction tool 10 comes out of the second suction tool 6 (extension pipe 5) by the operation before θ becomes 90 degrees or more, that is, the operation for making the angle θ 60 degrees or more. ing.

なお、凹溝50の後側傾斜部53も、底面部51から後側へ向けて鈍角となるように傾斜して形成されている。
また、凹溝50の深さは、球状部材46の直径の2/3以上となるように設定されることが好ましく、さらに、球状部材46の直径の3/4程度に設定されることが好ましい。
Note that the rear inclined portion 53 of the groove 50 is also formed to be inclined so as to have an obtuse angle from the bottom portion 51 toward the rear side.
Further, the depth of the concave groove 50 is preferably set to be 2/3 or more of the diameter of the spherical member 46, and is preferably set to about 3/4 of the diameter of the spherical member 46. .

このような凹溝50に対応する収容室S2には、凹溝50の前側傾斜部52に連続するように戻り用の傾斜部62が形成されている。収容室S2は、天部61と、傾斜部62とを備えて構成され、収容室S2の後側には、球状部材46を凹溝50側と収容室S2側とに振り分けるための振分部材63が配置されている。   In the accommodation chamber S <b> 2 corresponding to the concave groove 50, a return inclined portion 62 is formed so as to be continuous with the front inclined portion 52 of the concave groove 50. The storage chamber S2 includes a top portion 61 and an inclined portion 62, and a sorting member for distributing the spherical member 46 between the concave groove 50 side and the storage chamber S2 side on the rear side of the storage chamber S2. 63 is arranged.

天部61は、凹溝50の底面部51と略平行とされており、図17に二点鎖線で示すように、球状部材46は、この天部61と振分部材63の内面63aとの間に保持されて解除位置を採るように構成されている。
傾斜部62は、前側へ向けて凹状とされた(円弧状とされた)斜面を形成しており、収容室S2内に球状部材46が位置するときに、解除位置側(収容室S2側)から保持位置側(凹溝50側)へ向けて球状部材46が自然に転動するのを補助する(転動し易くする)役割をなす。
The top portion 61 is substantially parallel to the bottom surface portion 51 of the concave groove 50, and as shown by a two-dot chain line in FIG. 17, the spherical member 46 is formed between the top portion 61 and the inner surface 63 a of the sorting member 63. It is comprised so that it may be held between and the release position may be taken.
The inclined portion 62 forms an inclined surface that is concave (arc-shaped) toward the front side, and when the spherical member 46 is located in the storage chamber S2, the release position side (the storage chamber S2 side). It serves to assist the spherical member 46 from rolling naturally toward the holding position side (concave groove 50 side) (to facilitate rolling).

振分部材63は、球状部材46を凹溝50側と収容室S2側とに振り分けるためのくさび形状の突出部63bを有している。突出部63bは、先端部63cが収容室S2側(収容室S2内)に位置しており、先端部63cよりも下側(凹溝50側)には、凹溝50に対向するように傾斜した当接面63dが形成されている。この当接面63dには、球状部材46が当接可能であり、凹溝50内に球状部材46がある状態で延長管5が上方向(矢印A1方向、図18(a)参照)に引き上げ操作された際に、球状部材46が当接面63dに当接してスライド部材41の移動を規制するようになっている。
なお、突出部63bの先端部63cは、凹溝50と収容室S2との境界位置となるように配置してもよく、球状部材46の振り分けが所望の角度θで行われるように形状を変更することもできる。
The distribution member 63 has a wedge-shaped protrusion 63b for distributing the spherical member 46 to the concave groove 50 side and the storage chamber S2 side. The protrusion 63b has a tip 63c positioned on the storage chamber S2 side (inside the storage chamber S2), and is inclined so as to face the groove 50 below the tip 63c (on the groove 50 side). The contact surface 63d is formed. The spherical member 46 can abut on the abutting surface 63d, and the extension pipe 5 is pulled upward (in the direction of arrow A1, see FIG. 18A) with the spherical member 46 in the concave groove 50. When operated, the spherical member 46 comes into contact with the contact surface 63d to restrict the movement of the slide member 41.
Note that the tip 63c of the protrusion 63b may be disposed so as to be a boundary position between the groove 50 and the storage chamber S2, and the shape is changed so that the spherical member 46 is distributed at a desired angle θ. You can also

次に、第1の吸込具10と第2の吸込具6との接続を解除する際の作用について説明する。
はじめに、図18(a)に示すように、基準面F(図示しない被清掃面)と延長管5の軸心O1(ここでは軸心O1に平行な線O1’)とのなす角度θが60度未満となる45度(一般的な使用状態における角度)である状態では、球状部材46が、凹溝50内にあって、底面部51と前側傾斜部52とに跨るようにして位置して保持位置にある。この状態で、延長管5を上方向(矢印A1方向)に引き上げ操作しても、球状部材46が振分部材63の当接面63dに当接することとなるため、スライド部材41のスライドのロックが保持され、スライド部材41の移動が規制される。
Next, the action when releasing the connection between the first suction tool 10 and the second suction tool 6 will be described.
First, as shown in FIG. 18 (a), an angle θ formed by a reference plane F (surface to be cleaned not shown) and the axis O1 of the extension pipe 5 (here, a line O1 ′ parallel to the axis O1) is 60. In a state of 45 degrees (an angle in a general use state) that is less than 50 degrees, the spherical member 46 is located in the concave groove 50 so as to straddle the bottom surface portion 51 and the front inclined portion 52. In the holding position. In this state, even if the extension tube 5 is pulled upward (in the direction of arrow A1), the spherical member 46 comes into contact with the contact surface 63d of the distribution member 63, so that the slide of the slide member 41 is locked. Is held, and the movement of the slide member 41 is restricted.

次に、図18(b)に示すように、基準面Fと延長管5の軸心O1(線O1’)とのなす角度θが一般的な使用状態よりも高くなる60度に持ち上げられると、凹溝50の底面部51が基準面Fと平行になり、球状部材46が保持位置側(凹溝50側)から解除位置側(収容室S2側)に転動(移動)可能となる。
さらに、図18(c)に示すように、基準面Fと延長管5の軸心O1(線O1’)とのなす角度θが60度より大きくなると、球状部材46が解除位置側(収容室S2側)に向けて自然に転動(移動)し、前側傾斜部52側から傾斜部62側に転動する。この状態で、延長管5を上方向(矢印A1方向)に引き上げ操作すると、振分部材63の突出部63bに球状部材46が当接し、球状部材46が弾かれるようにして収容室S2側に移動する(図18(d)参照)。これによって、球状部材46によるスライド部材41のロックが解除され、スライド部材41の位置変更(第1の位置から第2の位置への変更)が可能となる。
なお、基準面Fと延長管5の軸心O1(線O1’)とのなす角度θが60度であるときにも、延長管5を持ち上げるときの勢い等で、球状部材46が解除位置側(収容室S2側)に向けて移動可能であり、スライド部材41の位置変更が可能である。
Next, as shown in FIG. 18B, when the angle θ formed by the reference plane F and the axis O1 (line O1 ′) of the extension pipe 5 is raised to 60 degrees, which is higher than in a general use state. The bottom surface portion 51 of the groove 50 is parallel to the reference surface F, and the spherical member 46 can roll (move) from the holding position side (the groove 50 side) to the release position side (the storage chamber S2 side).
Further, as shown in FIG. 18 (c), when the angle θ formed by the reference plane F and the axis O1 (line O1 ′) of the extension pipe 5 is larger than 60 degrees, the spherical member 46 is moved to the release position side (container chamber). Rolls (moves) naturally toward (S2 side) and rolls from the front inclined portion 52 side to the inclined portion 62 side. In this state, when the extension pipe 5 is pulled up (in the direction of arrow A1), the spherical member 46 comes into contact with the protruding portion 63b of the sorting member 63, and the spherical member 46 is repelled toward the accommodation chamber S2. It moves (see FIG. 18D). Thereby, the lock of the slide member 41 by the spherical member 46 is released, and the position of the slide member 41 can be changed (change from the first position to the second position).
Even when the angle θ between the reference plane F and the axis O1 (line O1 ′) of the extension tube 5 is 60 degrees, the spherical member 46 is moved to the release position side due to the momentum when the extension tube 5 is lifted. It can move toward (accommodating chamber S2 side), and the position of the slide member 41 can be changed.

したがって、第1の吸込具10と第2の吸込具6(延長管5)との接続のロックを解除して、これらを容易に取り外すことができる。   Accordingly, the connection between the first suction tool 10 and the second suction tool 6 (extension pipe 5) is unlocked, and these can be easily removed.

一方、第1の吸込具10から第2の吸込具6(延長管5)が外されると、一対のコイルばね38(図5(a)(b)参照)の付勢力によってスライド部材41が第2の位置から第1の位置へ戻される。これによって、球状部材46が収容室S2側から凹溝50側に転動して戻される。この際、収容室S2に形成された傾斜部62によって、収容室S2側から凹溝50側へ球状部材46がスムーズに転動され、球状部材46が凹溝50内に確実に戻されることとなる。   On the other hand, when the second suction tool 6 (extension pipe 5) is removed from the first suction tool 10, the slide member 41 is moved by the urging force of the pair of coil springs 38 (see FIGS. 5A and 5B). Returned from the second position to the first position. Thereby, the spherical member 46 rolls back from the storage chamber S2 side to the concave groove 50 side. At this time, the spherical member 46 smoothly rolls from the storage chamber S2 side to the concave groove 50 side by the inclined portion 62 formed in the storage chamber S2, and the spherical member 46 is reliably returned to the concave groove 50. Become.

このような構成を備えることによって、基準面Fと延長管5の軸心O1(線O1’)とのなす角度θが60度以上となる操作に応じて、第1の吸込具10が第2の吸込具6から外れるので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止しつつ、清掃時の角度(略45度)から少し持ち上げた角度(60度)で第1の吸込具10が第2の吸込具6から外れるようになり、扱い易さが増して、より一層使い勝手のよい電気掃除機1が得られる。   By providing such a configuration, the first suction tool 10 is in the second state in response to an operation in which the angle θ formed by the reference plane F and the axis O1 (line O1 ′) of the extension pipe 5 is 60 degrees or more. The first suction tool 10 is lifted slightly from the cleaning angle (approximately 45 degrees) while reliably preventing the first suction tool 10 from being accidentally detached from the second suction tool 6 during cleaning. The first suction tool 10 comes off from the second suction tool 6 at an angle (60 degrees), the handling is increased, and the vacuum cleaner 1 that is more convenient to use is obtained.

また、清掃時の角度(略45度)から少し持ち上げた角度(60度)で第1の吸込具10が第2の吸込具6から外れるようになるので、前記実施形態のように、基準面Fと延長管5の軸心O1(線O1’)とのなす角度θが90度以上となる前の段階で取り外し操作を開始することができ、取り外し操作を無理なく行うことができて扱い易い電気掃除機1が得られる。   Further, since the first suction tool 10 comes off from the second suction tool 6 at an angle (60 degrees) slightly lifted from the angle at the time of cleaning (approximately 45 degrees), as in the above embodiment, the reference surface The removal operation can be started before the angle θ formed by F and the axis O1 (line O1 ′) of the extension pipe 5 reaches 90 degrees or more, and the removal operation can be performed without difficulty and is easy to handle. The vacuum cleaner 1 is obtained.

また、振分部材63は、くさび形状の突出部63bを有しているので、先端部63cで球状部材46がうまく弾かれるようになり、振り分けを確実に行うことができる。したがって、扱い易く、より一層使い勝手のよい電気掃除機1が得られる。   Further, since the sorting member 63 has the wedge-shaped protrusion 63b, the spherical member 46 can be repelled well at the tip 63c, and the sorting can be performed reliably. Therefore, the vacuum cleaner 1 that is easy to handle and more convenient to use can be obtained.

(第4実施形態)
本実施形態が前記第1、第2実施形態と異なるところは、係合部40からスライド部材41を排除した点にある。
図19、図20(a)(b)に示すように、第2の継手30Bに形成される係合部40’は、筒状接続部33の上面に形成された四角い凹溝内に、四角い枠部材42が嵌め込まれてなり、凹溝内には、前部側が深く、後部側が浅く形成された段付き状の底面部41a’、41b’が形成されている。そして、底面部41a’、41b’の境界部分には、第2の吸込具6の係合部材6aが係止される係止面43c’(図20(b)を併せて参照)が形成されている。
(Fourth embodiment)
This embodiment is different from the first and second embodiments in that the slide member 41 is excluded from the engaging portion 40.
As shown in FIGS. 19, 20 (a) and 20 (b), the engaging portion 40 ′ formed on the second joint 30 </ b> B is square in the rectangular groove formed on the upper surface of the cylindrical connecting portion 33. A frame member 42 is fitted, and stepped bottom surface portions 41a ′ and 41b ′ are formed in the concave groove. The stepped bottom portions 41a ′ and 41b ′ are formed so that the front side is deep and the rear side is shallow. And in the boundary part of bottom face part 41a ', 41b', locking surface 43c '(refer also FIG.20 (b) is combined) by which the engaging member 6a of the 2nd suction tool 6 is locked is formed. ing.

このような係合部40’では、接続時に、第2の継手30Bに第2の吸込具6を嵌め込んでいくと、係合部材6aが、付勢力によって凹溝内に入り込み、底面部41b’に当接しながら凹溝内を前方へ進む状態となる。そして、さらに第2の継手30Bに第2の吸込具6を嵌め込んでいくと、凹溝内を前方へ進んできた係合部材6aが、接続の終端で底面部41b’から底面部41a’に移動し、係止面43c’に当接するようにして係止される(図20(a)(b)参照)こととなる。これによって、第2の継手30Bに第2の吸込具6を接続することができる(図21(a)参照)。   In such an engaging portion 40 ′, when the second suction tool 6 is fitted into the second joint 30B at the time of connection, the engaging member 6a enters the concave groove by the biasing force, and the bottom surface portion 41b. It will be in a state of moving forward in the groove while contacting '. Then, when the second suction tool 6 is further fitted into the second joint 30B, the engaging member 6a that has advanced forward in the concave groove is changed from the bottom surface portion 41b ′ to the bottom surface portion 41a ′ at the end of the connection. And is locked so as to come into contact with the locking surface 43c ′ (see FIGS. 20A and 20B). Thus, the second suction tool 6 can be connected to the second joint 30B (see FIG. 21A).

また、接続の解除時には、図21(b)に示すように、第2の継手30Bを第2の吸込具6から引き抜く操作を行うと(矢印A1方向の力を作用させると)、係合部材6aは、底面部41a’から係止面43c’を乗り越えて底面部41b’に移動し、底面部41b’に当接しながら凹溝内を後方へ進んで、第2の面42aに当接する(図20(a)(b)参照)。
ここで、第2の吸込具6を、図21(c)に示すように、矢印B1方向にひねると、図20(a)に示すように、切欠部45を通じて係合部材6aが係合部40’から離脱する。これによって、第2の吸込具6から第2の継手30Bを切り離すことができる。
When the connection is released, as shown in FIG. 21B, when the second joint 30B is pulled out from the second suction tool 6 (when a force in the direction of the arrow A1 is applied), the engaging member 6a moves from the bottom surface portion 41a ′ to the bottom surface portion 41b ′ over the locking surface 43c ′, moves backward in the groove while contacting the bottom surface portion 41b ′, and contacts the second surface 42a ( (See FIGS. 20A and 20B).
Here, when the second suction tool 6 is twisted in the direction of the arrow B1 as shown in FIG. 21C, the engaging member 6a is engaged with the engaging portion through the notch 45 as shown in FIG. Leave 40 '. Thus, the second joint 30B can be disconnected from the second suction tool 6.

このような係合部40’を有する電気掃除機1によれば、使用者による操作管4への引っ張り操作およびひねり操作によって、第1の吸込具10を第2の吸込具6から切り離すことができる。つまり、2つの異なる操作を行う(2つの異なる方向の力を作用させる)ことによって、第1の吸込具10が第2の吸込具6から切り離されるので、清掃中に不意に第1の吸込具10が第2の吸込具6から外れてしまうのを確実に防止することができ、使い勝手の良い電気掃除機1が得られる。   According to the vacuum cleaner 1 having such an engaging portion 40 ′, the first suction tool 10 can be separated from the second suction tool 6 by a pulling operation and a twisting operation on the operation tube 4 by the user. it can. That is, since the first suction tool 10 is separated from the second suction tool 6 by performing two different operations (acting forces in two different directions), the first suction tool unexpectedly during cleaning. Thus, it is possible to reliably prevent 10 from being detached from the second suction tool 6 and to obtain a vacuum cleaner 1 that is easy to use.

なお、底面部41a’、41b’を同じ深さに形成して、係止面43c’の代わりに、係合部材6aが係止される溝部を底面部41a’、41b’に形成してもよい。
また、溝部は必ずしも形成する必要はなく、傾斜状(テーパ状)等の底面部としてもよい。
Note that the bottom surface portions 41a 'and 41b' are formed to the same depth, and the groove portions to which the engaging member 6a is locked are formed in the bottom surface portions 41a 'and 41b' instead of the locking surface 43c '. Good.
Further, the groove portion is not necessarily formed, and may be a bottom surface portion such as an inclined shape (tapered shape).

なお、前記各実施形態において、各部の形状等は任意に設定することができ、スライド部材41の円周方向の幅や長さ等も任意に設定することができる。   In each of the above embodiments, the shape and the like of each part can be arbitrarily set, and the width and length of the slide member 41 in the circumferential direction can also be arbitrarily set.

また、前記実施形態において移動部材は、球状部材46にて説明したが、これに限られることはなく、転動可能な円柱状の部材であってもよい。   In the above-described embodiment, the moving member has been described with the spherical member 46. However, the moving member is not limited to this and may be a rollable columnar member.
