Therefore, the outer surface diameter of the opening end of the bowl-shaped portion 206 is gradually narrowed toward the tip, and the outer surface diameter in the middle of the narrowing is the inner side of the opening end of the hand operating portion 12 or the extension tube 13. It preferably corresponds to (coincides with) the surface diameter.

前継手２０２の樽形状部２０８は、後継手２０１の椀形状部２０６及び、椀形状カバー２０４の内側表面を略オフセットした形状であり、椀形状部２０６と椀形状カバー２０４に摺動可能（回動可能）に当接して組み立てられる。椀形状部２０６と椀形状カバー２０４には、それぞれ切り欠き部２０９，２１０があり、前継手２０２は切り欠き部の上端２１１と下端２１２の間を回動できる。前継手２０２と椀形状カバーの間には、回動角度位置を知らしめるノッチ感（クリック感）を発生させるノッチリング２０３を配置している。ノッチリング２０３は、円環形状で内周に回り止め突起２１３を有し、外周にはノッチ感を（クリック感）発生させるノッチ突起２１４（突起）を有し、ノッチ突起２１４は前継手２０２の樽形状部２０８の椀形状カバー２０４が当接する側の底面に設けた回り止め溝２１５に挿入してあり、前継手２０２と一緒に回動するようになっている。ただし、このような構造であるため、後継手２０１と前継手２０２との回動範囲は、３６０度ではなく、所定の範囲に限定される。   The barrel-shaped portion 208 of the front joint 202 has a shape in which the flange-shaped portion 206 of the rear joint 201 and the inner surface of the flange-shaped cover 204 are substantially offset, and can slide on the flange-shaped portion 206 and the flange-shaped cover 204 ( It is assembled in contact with the movable). The hook-shaped portion 206 and the hook-shaped cover 204 have cutout portions 209 and 210, respectively, and the front joint 202 can rotate between the upper end 211 and the lower end 212 of the cutout portion. A notch ring 203 that generates a notch feeling (click feeling) that informs the rotational angle position is disposed between the front joint 202 and the saddle-shaped cover. The notch ring 203 has an annular shape and has a non-rotating protrusion 213 on the inner periphery, and has a notch protrusion 214 (protrusion) that generates a notch feeling (click feeling) on the outer periphery. The barrel-shaped portion 208 is inserted into a rotation-preventing groove 215 provided on the bottom surface of the barrel-shaped portion 204 on the side where it comes into contact, and is rotated together with the front joint 202. However, since it is such a structure, the rotation range of the rear joint 201 and the front joint 202 is limited to a predetermined range, not 360 degrees.

図３に示すように椀形状カバー２０４の内側底面には、ノッチリング２０３の外周のノッチ突起２１４を押し込み、ノッチリング２０３をたわませる略円形リブ２１６があり、この円形リブ２１６にはノッチリング２０３の外周のノッチ突起２１４を押し込まない凹み部２１７が所定の角度に形成されている。これにより後継手２０１と前継手２０２は、椀形状部２０６と樽形状部２０８の中心軸を軸として回動可能で、ノッチリング２０３はノッチ突起２１４が略円形リブ２１６の凹み部２１７内に収まっていて、前継手２０２の回動に際しノッチリング２０３は前継手２０２と一緒に回動し、ノッチ突起２１４は凹み部２１７を乗り上げてリングの半径方向にたわみ、略円形リブ２１６に当接しながら回動先の凹み部２１７へ到達し、たわみが解放されて凹み部２１７に収まり、この収まりによって回動角度位置はある程度固定されるのである。   As shown in FIG. 3, a substantially circular rib 216 that pushes the notch protrusion 214 on the outer periphery of the notch ring 203 and deflects the notch ring 203 is formed on the inner bottom surface of the saddle-shaped cover 204, and the circular rib 216 includes a notch ring. A recess 217 that does not push the notch protrusion 214 on the outer periphery of 203 is formed at a predetermined angle. As a result, the rear joint 201 and the front joint 202 can rotate about the central axes of the bowl-shaped portion 206 and the barrel-shaped portion 208, and the notch ring 203 has the notch projection 214 within the recessed portion 217 of the substantially circular rib 216. When the front joint 202 is rotated, the notch ring 203 rotates together with the front joint 202, and the notch protrusion 214 rides on the recessed portion 217 and bends in the radial direction of the ring and rotates while contacting the substantially circular rib 216. The movement reaches the recess 217 of the moving destination, and the deflection is released and fits in the recess 217, and the rotation angle position is fixed to some extent by this fit.

本実施例においては、ノッチ突起２１４の個数は２個で、凹み部２１７の箇所は２箇所であるが、本構成に限定されるものではない。ノッチリング２０３の設置については、本事例とは逆にノッチリング２０３を挿入する溝２１５を椀形状カバー２０４に、ノッチリング２０３をたわませる円形リブ２１６を前継手２０２に形成してもよい。また、ノッチリング２０３は、後継手２０１と前継手２０２が当接する側にあってもよく、さらに、両側に設けて２個使いとすれば、それぞれのノッチリングに掛かるたわみ力を分散できて、信頼性を向上することができる。ノッチ感を発生させる方法は、本事例の方法に限定されるものではなく、例えばリングの代わりにコイルバネを、ノッチ突起の代わりに鋼球を使用すれば、同様の効果を得られるのである。   In the present embodiment, the number of notch protrusions 214 is two and the number of recesses 217 is two, but the present invention is not limited to this configuration. Concerning the installation of the notch ring 203, the groove 215 for inserting the notch ring 203 may be formed in the saddle-shaped cover 204 and the circular rib 216 for bending the notch ring 203 may be formed in the front joint 202. Further, the notch ring 203 may be on the side where the rear joint 201 and the front joint 202 abut, and further, if two are used on both sides, the bending force applied to each notch ring can be dispersed, Reliability can be improved. The method of generating the notch feeling is not limited to the method of this example. For example, if a coil spring is used instead of the ring and a steel ball is used instead of the notch projection, the same effect can be obtained.

The distal end of the blade body 302 has the narrowest width in the suction tool 100 and is formed so as to be inclined (tapered) from the distal end toward the lower side of the other end. With the connecting pipe 300 connected to the operation unit 12 or the extension pipe 13, the gaps and the like can be cleaned. That is, the tip of the blade body 302 forms a clearance inlet (nozzle). Further, the leading end of the blade body 302 serves as a connection portion with the rotational connection portion 400, and a retaining protrusion 306 is formed at the connection portion when the blade body 302 is connected to the rotational connection portion 400. As in the present embodiment, it is preferable that the user can easily separate the connection tube 300 and the rotation connection portion 200, but the user can easily separate the connection tube 300 and the rotation connection portion 200 from each other. A non-separable connection structure may be used.

As shown in FIGS. 6 and 7, the stopper 303 is biased by an elastic body 307 such as a spring in a direction in which the claw portion 308 fits into a plurality of recessed portions 309 formed on the outer surface of the blade body 302. The expansion / contraction position of the blade body 302 is fixed. While the user presses the stopper 303 with a finger against the bias of the elastic body 307, the claw portion 308 is separated from the recessed portion 309 of the blade body 302, so that the blade body 302 can be freely expanded and contracted. .

It is comprised from the suction inlet formation part 426 which provided the processus | protrusion 425. FIG. The rotation part 408 and the rotation cover 405 of the front joint 402 are assembled so as to be slidable with respect to the rotation base part 407 so as to cover the rotation base part 407 of the rear joint 401. A cylindrical shaft protrusion 427 is provided on both side surfaces of the end of the front joint 402 opposite to the rotating portion 408, and a cylindrical slide protrusion 428 is provided above the shaft protrusion 427.

前継手４０２の回動部４０８と回動カバー４０５には、それぞれ切り欠き部４１０，４１１があり、前継手４０２は切り欠き部の上端部４１２と下端部４１３が後継手４０１に突き当たるまでの間を回動できる。回動ベース部４０７と回動部４０８の接続間には、回動角度位置を知らしめるノッチ感を発生させるノッチリング４０３を配置している。ノッチリング４０３は、ノッチリング２０３と同様な形状であり、回り止め突起４１４とノッチ突起４１５（突起）を有し、後継手４０１の回動ベース部４０７の側面に設けた回り止め溝４１６に挿入してある。   The pivoting portion 408 and the pivoting cover 405 of the front joint 402 have notches 410 and 411, respectively. The front joint 402 is a time until the upper end portion 412 and the lower end portion 413 of the notch portion abut against the rear joint 401. Can be rotated. A notch ring 403 that generates a notch feeling that informs the rotation angle position is arranged between the rotation base portion 407 and the rotation portion 408. The notch ring 403 has the same shape as the notch ring 203, has a non-rotating projection 414 and a notch projection 415 (protrusion), and is inserted into a detent groove 416 provided on the side surface of the rotation base portion 407 of the rear joint 401. It is.

前継手４０２の回動部４０８には、ノッチリング４０３の外周のノッチ突起４１５を押し込みノッチリング４０３をたわませる略円形穴４１７があり、この円形穴４１７にはノッチリング４０３の外周のノッチ突起２１４を押し込まない凹み部４１８が所定の角度に形成されている。また、回動部４０８には爪穴４１９が形成されており、蓋体４０４は爪４２０を嵌め合わせ固定されている。   The rotating portion 408 of the front joint 402 has a substantially circular hole 417 that pushes the notch protrusion 415 on the outer periphery of the notch ring 403 and deflects the notch ring 403, and the circular hole 417 has a notch protrusion on the outer periphery of the notch ring 403. A recess 418 that does not push 214 is formed at a predetermined angle. Further, a claw hole 419 is formed in the rotating portion 408, and the claw 420 is fitted and fixed to the lid 404.

これにより後継手４０１と前継手４０２は、回動ベース部４０７と回動部４０８の中心軸を軸として回動可能で、ノッチリング４０３はノッチ突起４１５が略円形穴４１７の凹み部４１８内に収まっていて、前継手４０２の回動に際し、ノッチ突起４１５は凹み部４１８を乗り上げてリングの半径方向にたわみ、略円形穴４１７に当接しながら回動先の凹み部４１８へ到達し、たわみが解放されて凹み部４１８に収まり、この収まりによって回動角度位置はある程度固定されるのである。   As a result, the rear joint 401 and the front joint 402 can rotate about the central axes of the rotation base portion 407 and the rotation portion 408, and the notch ring 403 has the notch protrusion 415 in the recess 418 of the substantially circular hole 417. When the front joint 402 is rotated, the notch protrusion 415 rides on the recess 418 and bends in the radial direction of the ring, reaches the recess 418 at the rotation destination while contacting the substantially circular hole 417, and the deflection is It is released and fits in the recess 418, and the rotational angle position is fixed to some extent by this fit.

本実施例においては、ノッチ突起４１５の個数は２個で、ノッチする箇所は２箇所であるが、本構成に限定されるものではない。ノッチリング４０３の設置については、本実施例とは逆にノッチリング４０３を挿入する溝４１６を前継手４０２に、ノッチリング４０３をたわませる略円形穴４１７を後継手４０１に形成してもよい。また、ノッチリング４０３は、後継手４０１と回動カバー４０５が当接する側にあってもよく、さらに、両側に設けて２個使いとすれば、それぞれのノッチリングに掛かるたわみ力を分散できて、信頼性を向上することができる。ノッチ感（クリック感）を発生させる方法は、本事例の方法に限定されるものではなく、例えばリングの代わりにコイルバネを、ノッチ突起の代わりに鋼球を使用すれば、同様の効果を得られるのである。ただし、このような構造であるため、後継手４０１と前継手４０２との回動範囲は、３６０度ではなく、所定の範囲に限定される。 回動軸体４２４の左右側面には、軸突起４２６と軸支し前継手４０２と連結する連結穴４２３と、摺動突起４２８を固定し前継手４０２の位置決めをする摺動穴４２９を形成している。摺動穴４２９は、連結穴４２３よりも上側に形成され、側面のそれぞれに２個づつ形成される。軸突起４２７と連結穴４２３にて形成される連結部４３２を軸に、先端部に向かって前継手４０２の上面方向に回動することができ、一方の摺動穴４２９に収まっていた摺動突起４２８は、一方の摺動穴４２９を乗り上げて回動軸体４２４の側面を外側にたわませながら当接し、回動先の他方の摺動穴４２９へ収まることで、前継手４０２に対する回動軸体４２４の回動角度位置は固定されるのである。吸口形成部４２６は、回動軸体４２４に対して３６０度回動可能である。そして、図１９（Ａ）（Ｂ）に示すように、後継手４０１または前継手４０２の軸方向に対して、吸口形成部４２６の長手方向が略９０度になった状態で回動接続部４００を上側から見ると、回動接続部４００は略Ｔ字形状となる。図１９（Ｅ）（Ｆ）に示すように、後継手４０１または前継手４０２の軸方向に対して、吸口形成部４２６の長手方向が略一致した状態で回動接続部４００を上側から見ると、回動接続部４００は略Ｉ字形状となる。特許文献４や非特許文献１と同様に、吸込具１００を延長管１３の側面に取り付けて収納する際には、回動接続部４００は略Ｉ字形状とするのが好ましい。   In the present embodiment, the number of the notch protrusions 415 is two and the number of notches is two, but the present invention is not limited to this configuration. Concerning the installation of the notch ring 403, contrary to the present embodiment, a groove 416 for inserting the notch ring 403 may be formed in the front joint 402, and a substantially circular hole 417 for bending the notch ring 403 may be formed in the rear joint 401. . Further, the notch ring 403 may be provided on the side where the rear joint 401 and the rotation cover 405 are in contact with each other. Further, if two are provided on both sides, the bending force applied to each notch ring can be dispersed. , Reliability can be improved. The method of generating the notch feeling (click feeling) is not limited to the method of this example. For example, if a coil spring is used instead of the ring and a steel ball is used instead of the notch protrusion, the same effect can be obtained. It is. However, because of such a structure, the rotation range of the rear joint 401 and the front joint 402 is limited to a predetermined range, not 360 degrees. On the left and right side surfaces of the rotating shaft body 424, there are formed a connecting hole 423 that pivotally supports the shaft protrusion 426 and connects to the front joint 402, and a sliding hole 429 that fixes the sliding protrusion 428 and positions the front joint 402. ing. The sliding holes 429 are formed above the connecting holes 423 and two are formed on each side surface. A sliding portion that can be rotated in the direction of the upper surface of the front joint 402 toward the tip end with the connecting portion 432 formed by the shaft protrusion 427 and the connecting hole 423 as an axis, and has been accommodated in one sliding hole 429. The protrusion 428 rides on one sliding hole 429 and comes into contact with the side surface of the rotating shaft body 424 while bending outward, and fits into the other sliding hole 429 at the rotation destination, thereby rotating the front joint 402. The rotational angle position of the moving shaft body 424 is fixed. The suction port forming portion 426 can rotate 360 degrees with respect to the rotation shaft body 424. Then, as shown in FIGS. 19A and 19B, the rotation connecting portion 400 is in a state in which the longitudinal direction of the suction port forming portion 426 is approximately 90 degrees with respect to the axial direction of the rear joint 401 or the front joint 402. When viewed from above, the rotation connecting portion 400 is substantially T-shaped. As shown in FIGS. 19 (E) and 19 (F), when the rotational connection portion 400 is viewed from above in a state where the longitudinal direction of the suction port forming portion 426 substantially matches the axial direction of the rear joint 401 or the front joint 402. The rotation connecting portion 400 is substantially I-shaped. As in Patent Document 4 and Non-Patent Document 1, when the suction tool 100 is attached to the side surface of the extension tube 13 and stored, the rotational connection portion 400 is preferably substantially I-shaped.

図１７に示すように、吸口形成部４２６の吸口（開口）の内面は、吸口形成部４２６の長手方向の端部から中央部に向かって傾斜しており、それに伴って、吸口形成部４２６の吸口（開口）の反対側の外面（上面）も、吸口形成部４２６の長手方向の端部から中央部に向かって傾斜しており、横断面では台形をしている。つまり、吸口形成部４２６の長手方向を横から見ると、左右対称である。尚、吸口形成部４２６の短手方向を横から見ても、左右対称である。このように、吸口形成部４２６の吸口（開口）の内面が傾斜しているため、吸口形成部４２６の吸口（開口）から通気穴４３０へ向かう空気の流れの乱れが少なくなる。そして、吸口形成部４２６の上面の吸口形成部４２６の長手方向の中央部かつ吸口形成部４２６の短手方向の中央部に、回動突起４２５が形成される。回動突起４２５の内側に通気穴４３０が形成され、通気可能である。通気穴４３０は略円形状であり、回動突起４２５はその通気穴４３０の周囲に複数形成される。複数の回動突起４２５が形成された円の中心が、回動軸体４２４に対する吸口形成部４２６の回動軸心となる。尚、複数の回動突起４２５が形成された円の中心は、通気穴４３０の中心、回動穴４３３の中心とも一致する。図１８（Ｂ）中の一点破線は、吸口形成部４２６の長手方向の中心線と、吸口形成部４２６の短手方向の中心線を示す。回動軸体４２４に対する吸口形成部４２６の回動軸心は、吸口形成部４２６の長手方向の中央でかつ吸口形成部４２６の短手方向の中央、つまり図１８（Ｂ）に示すように吸口形成部４２６の長手方向の中心線と吸口形成部４２６の短手方向の中心線の交点に位置するのが好ましい。つまり、回動軸体４２４に対する吸口形成部４２６の回動軸心から吸口形成部４２６の長手方向の両端面（端部）への距離は等しくなり、回動軸体４２４に対する吸口形成部４２６の回動軸心から吸口形成部４２６の短手方向の両端面（端部）への距離は等しくなる。またこの場合は、後継手４０１の軸心上または前継手４０２の軸心上または接続管３００の軸心上に、回動軸体４２４に対する吸口形成部４２６の回動軸心が存在することとなる。これによって、使用者が、吸込具１００を手前と奥の往復操作および左右の往復操作の際に、回動接続部４００の動きが安定し、それ故、操作性が向上する。   As shown in FIG. 17, the inner surface of the suction port (opening) of the suction port forming portion 426 is inclined from the end portion in the longitudinal direction of the suction port forming portion 426 toward the center portion. The outer surface (upper surface) on the opposite side of the suction port (opening) is also inclined from the longitudinal end of the suction port forming portion 426 toward the central portion, and has a trapezoidal shape in the cross section. That is, when the longitudinal direction of the suction port forming part 426 is viewed from the side, it is symmetrical. In addition, even if it looks at the transversal direction of the suction inlet formation part 426 from the side, it is left-right symmetric. Thus, since the inner surface of the suction port (opening) of the suction port forming portion 426 is inclined, the disturbance of the air flow from the suction port (opening) of the suction port forming portion 426 toward the vent hole 430 is reduced. Then, a rotation protrusion 425 is formed at the central portion in the longitudinal direction of the suction port forming portion 426 on the upper surface of the suction port forming portion 426 and the central portion in the short side direction of the suction port forming portion 426. A ventilation hole 430 is formed inside the rotation projection 425 so that ventilation is possible. The ventilation hole 430 has a substantially circular shape, and a plurality of rotation protrusions 425 are formed around the ventilation hole 430. The center of the circle formed with the plurality of rotation protrusions 425 becomes the rotation axis of the suction port forming portion 426 with respect to the rotation shaft body 424. Note that the center of the circle formed with the plurality of rotation protrusions 425 coincides with the center of the vent hole 430 and the center of the rotation hole 433. A dashed line in FIG. 18B indicates a center line in the longitudinal direction of the mouthpiece forming portion 426 and a center line in the short direction of the mouthpiece forming portion 426. The rotation axis of the suction port forming portion 426 with respect to the rotation shaft body 424 is the center of the suction port forming portion 426 in the longitudinal direction and the center of the suction port forming portion 426 in the short direction, that is, as shown in FIG. It is preferable to be located at the intersection of the center line in the longitudinal direction of the forming part 426 and the center line in the short direction of the mouthpiece forming part 426. That is, the distance from the rotation axis of the suction port forming portion 426 to the rotation shaft body 424 to both end surfaces (end portions) in the longitudinal direction of the suction port formation portion 426 becomes equal, and the suction port formation portion 426 with respect to the rotation shaft body 424 has the same distance. The distance from the pivot axis to both end surfaces (end portions) in the short direction of the suction port forming portion 426 is equal. In this case, the rotational axis of the suction port forming portion 426 with respect to the rotational shaft body 424 exists on the axial center of the rear joint 401, the axial center of the front joint 402, or the axial center of the connecting pipe 300. Become. Accordingly, when the user performs the reciprocating operation of the suction tool 100 toward the front and the back and the reciprocating operation of the left and right, the movement of the rotary connecting portion 400 is stabilized, and thus the operability is improved.

図１７中の一点破線は、後継手４０１の筒形状部４０６の軸心、前継手４０１の筒形状部４０９の軸心を示す。前継手４０１は、後継手４０１に対して、上側に角度αまで回動可能である。角度αは、５度から１０度程度である。筒形状部４０９の上面と下面とは、略平行であるため、図１７に示すように、前継手４０１が後継手４０１に対して上側に角度αである状態では、筒形状部４０９の上面の形成方向および下面の形成方向も、後継手４０１の軸方向に対して上側に角度αをなす方向となる。回動接続部４００を略Ｉ字形状である状態において、吸口形成部４２６の上面と筒形状部４０９の下面とが対向し、吸口形成部４２６の上面と筒形状部４０９の下面の間隔は、０以上５ｍｍ以下であるのが好ましい。吸口形成部４２６の上面と筒形状部４０９の下面とが略平行であるのが好ましい。この場合は、吸口形成部４２６の上面は、後継手４０１の軸方向に対して上側に角度αをなす方向となる。よって、回動軸体４２４は、筒形状部４０９に対して、軸突起４２７を軸として、吸口形成部４２６の上面が後継手４０１の軸方向に対して上側に角度αをなす方向となるまで、回動するのが好ましい。上記したように、筒形状部４０９に対する回動軸体４２４の回動角度は、連結穴４２３と摺動穴４２９との相互位置関係によって定めることができる。そして、吸口形成部４２６の吸口面と筒形状部４０９の軸方向とが略平行となる場合には、吸口形成部４２６の上面と吸口形成部４２６の吸口面とのなす角度が、角度αとなる。さらに、図１７に示すように、吸口形成部４２６の回動軸体４２４との連結部（通気穴４３０の中心）つまり吸口形成部４２６の長手方向の中心から、吸口形成部４２６の長手方向の端部（端面）までの長さ、つまり吸口形成部４２６の長手方向の長さの１／２は、筒形状部４０９の軸方向の長さ、または筒形状部４０９の吸口形成部４２６との連結部の回動軸（回動穴４３３の中心）から筒形状部４０９の回動部４０８側端部（端面）までの長さ、または前継手４０２の吸口形成部４２６との連結部の回動軸（回動穴４３３の中心）から前継手４０２の後継手４０１との連結部の回動軸（回動部４０８の軸心）との長さと略同等または短いのが好ましい。これによって、連通軸方向から吸口形成部４２６の吸口を近づけることができ、吸口形成部４２６を後方へ配置することで回動接続部４００さらには吸込具１００全長を短くできるため、かさばらずに収納することができ、収納性を向上できる。後継手４０１と前継手４０２間で軸方向に回動するだけでなく、前継手４０２と回動軸体４２４間で軸方向に回動し、さらに、回動軸体４２４と吸口形成部４２６間で、軸方向とは異なる方向に回動するため、収納性が向上する。また、前継手４０１よりも先端側の重心が、前継手４０１の軸心上に近くなるため、収納時の安定性も増す。   A dashed line in FIG. 17 indicates the axis of the cylindrical portion 406 of the rear joint 401 and the axis of the cylindrical portion 409 of the front joint 401. The front joint 401 can be rotated up to an angle α with respect to the rear joint 401. The angle α is about 5 to 10 degrees. Since the upper surface and the lower surface of the tubular portion 409 are substantially parallel, as shown in FIG. 17, when the front joint 401 is at an angle α upward with respect to the rear joint 401, The formation direction and the formation direction of the lower surface are also directions that form an angle α upward with respect to the axial direction of the rear joint 401. In the state where the rotation connecting part 400 is substantially I-shaped, the upper surface of the suction port forming part 426 and the lower surface of the cylindrical part 409 are opposed to each other, and the interval between the upper surface of the suction port forming part 426 and the lower surface of the cylindrical part 409 is It is preferably 0 to 5 mm. It is preferable that the upper surface of the suction port forming portion 426 and the lower surface of the cylindrical portion 409 are substantially parallel. In this case, the upper surface of the suction port forming portion 426 is in a direction that forms an angle α upward with respect to the axial direction of the rear joint 401. Therefore, the rotating shaft body 424 has the axial protrusion 427 as an axis with respect to the cylindrical portion 409 until the upper surface of the suction port forming portion 426 is in a direction that forms an angle α upward with respect to the axial direction of the rear joint 401. It is preferable to rotate. As described above, the rotation angle of the rotation shaft body 424 with respect to the cylindrical portion 409 can be determined by the mutual positional relationship between the connection hole 423 and the slide hole 429. When the suction port surface of the suction port forming portion 426 and the axial direction of the cylindrical portion 409 are substantially parallel, the angle formed between the upper surface of the suction port forming portion 426 and the suction surface of the suction port forming portion 426 is the angle α. Become. Furthermore, as shown in FIG. 17, the longitudinal direction of the suction port forming portion 426 from the connecting portion (the center of the vent hole 430), that is, the longitudinal center of the suction port forming portion 426, of the suction port forming portion 426. The length to the end (end face), that is, ½ of the length in the longitudinal direction of the suction port forming portion 426 is the length in the axial direction of the cylindrical portion 409 or the suction port forming portion 426 of the cylindrical shape portion 409. The length from the rotation axis (center of the rotation hole 433) of the connecting portion to the end portion (end surface) of the cylindrical portion 409 on the rotating portion 408 side, or the rotation of the connecting portion with the inlet forming portion 426 of the front joint 402 It is preferable that the length is substantially equal to or shorter than the length of the connecting shaft between the moving shaft (center of the rotating hole 433) and the rear joint 401 of the front joint 402 (axial center of the rotating portion 408). Accordingly, the suction port of the suction port forming portion 426 can be brought closer from the communication axis direction, and the rotation connecting portion 400 and the suction tool 100 can be shortened in total length by arranging the suction port forming portion 426 rearward, so that it can be stored without being bulky. This can improve storage. It not only rotates in the axial direction between the rear joint 401 and the front joint 402 but also rotates in the axial direction between the front joint 402 and the rotary shaft body 424, and further between the rotary shaft body 424 and the suction port forming portion 426. Thus, since it rotates in a direction different from the axial direction, the storage property is improved. In addition, since the center of gravity on the tip side of the front joint 401 is close to the axis of the front joint 401, the stability during storage is also increased.

図１８（Ｂ）に示すように、吸口形成部４２６には、回動軸体４２４の底面にある回動穴４３３に挿入し吸口形成部４２６を連結する回動突起４２５が設けられ、回動軸方向に回動することができる。回動突起４２５には、ノッチリング２０３とノッチリング４０３と同様に回動角度位置を知らしめるノッチ感を発生させるノッチ突起４３５が形成され、回動軸体４２４の底面の凹み部４３４に収まっている。吸口形成部４２６の回動に際し、ノッチ突起４３５は凹み部４３４を乗り上げて回動穴４３３の半径方向にたわみ、略円形壁４３６に当接しながら略円形壁４３６の終端に到達したわみが解放される。凹み部４３４には次のノッチ突起４３５が収まり、この収まりによって回動角度位置はある程度固定されるのである。また、ノッチ突起４３５は抜け止め用の爪にもなっており、吸口形成部４２６が回動軸体４２４から抜けないようになっている。   As shown in FIG. 18B, the suction port forming portion 426 is provided with a rotation protrusion 425 that is inserted into a rotation hole 433 on the bottom surface of the rotation shaft body 424 and connects the suction port formation portion 426. It can rotate in the axial direction. Like the notch ring 203 and the notch ring 403, the rotation protrusion 425 is formed with a notch protrusion 435 for generating a notch feeling that informs the rotation angle position, and is fitted in the recess 434 on the bottom surface of the rotation shaft body 424. Yes. When the suction port forming portion 426 is rotated, the notch projection 435 rides on the recessed portion 434 and bends in the radial direction of the rotation hole 433, and the deflection reaching the end of the substantially circular wall 436 while being in contact with the substantially circular wall 436 is released. The The next notch protrusion 435 is accommodated in the recess 434, and the rotational angle position is fixed to some extent by this accommodation. The notch protrusion 435 also serves as a retaining claw so that the suction port forming portion 426 does not come off the rotating shaft body 424.

図１９（Ａ）に、回動接続部４００を略Ｔ字形状とした時の吸込具１００の上面図を示し、図１９（Ｂ）に、回動接続部４００を略Ｔ字形状とした時の回動接続部４００の上面図を示し、図１９（Ｃ）に、回動接続部４００を略Ｔ字形状とした時の吸込具１００の上断面図を示し、図１９（Ｄ）に、回動接続部４００を略Ｔ字形状とした時の回動接続部４００の上断面図を示し、図１９（Ｅ）に、回動接続部４００を略Ｉ字形状とした時の吸込具１００の上面図を示し、図１９（Ｆ）に、回動接続部４００を略Ｉ字形状とした時の回動接続部４００の上面図を示し、図１９（Ｇ）に、回動接続部４００を略Ｉ字形状とした時の吸込具１００の上断面図を示し、図１９（Ｈ）に、回動接続部４００を略Ｉ字形状とした時の回動接続部４００の上断面図を示す。図１９（Ｅ）（Ｆ）（Ｇ）（Ｈ）に示すように、吸口形成部４２６の短手方向の幅を、回動ベース部４０７や回動部４０８などで形成される連結部４３１の幅（軸方向に垂直な方向の幅）と略同等または短くする。また、吸口形成部４２６の短手方向の幅を、後継手４０１の幅または前継手４０２の幅と略同等または短くしてもよい。また、吸口形成部４２６の短手方向の幅を、接続管３００の最大幅と略同等または短くしてもよい。尚、接続管３００の最大幅は、接続部３０５に形成される。これによって、吸込具１００を延長管１３の側面に係合して収納する際に、吸口形成部４２６が出っ張って邪魔にならないため、収納性が向上する。さらに、使用者が、吸口形成部４２６の長手方向を、後継手４０１および前継手４０２の軸方向に沿った方向になるように、前継手４０２に対して吸口形成部４２６を回動して、吸口形成部４２６を略Ｉ字形状とすれば、奥まった狭いすき間を掃除することもできる。また、使用者が、吸口形成部４２６の長手方向が、後継手４０１および前継手４０２の軸方向と垂直な方向になるように、前継手４０２に対して吸口形成部４２６を回動して、吸口形成部４２６を略Ｔ字形状に回動させれば、掃除面を幅広にとることができ、使用者の前後方向（手前と奥の往復方向）の掃除面を多く取れるため前後させる回数を減らすことができ、清掃効率を向上することができる。さらに、吸口形成部４２６の長手方向の幅は吸口体１４の長手方向よりも短いため、吸口体１４の入らないすき間を掃除することができる。また、略Ｉ字形状よりも左右方向への摩擦面が少なくなることで抵抗が減り、使用者の手元への負担を減らすことができる。   FIG. 19A shows a top view of the suction tool 100 when the rotation connecting portion 400 has a substantially T shape, and FIG. 19B shows a case where the rotation connecting portion 400 has a substantially T shape. FIG. 19 (C) shows a top sectional view of the suction device 100 when the rotary connecting portion 400 is substantially T-shaped, and FIG. 19 (D) shows a top view of the rotary connecting portion 400 of FIG. An upper cross-sectional view of the rotational connection portion 400 when the rotational connection portion 400 is substantially T-shaped is shown. FIG. 19E shows the suction tool 100 when the rotational connection portion 400 is substantially I-shaped. FIG. 19F shows a top view of the rotation connecting portion 400 when the rotation connecting portion 400 is substantially I-shaped, and FIG. 19G shows the rotation connecting portion 400. FIG. 19H shows a top cross-sectional view of the suction tool 100 when the rotary connection portion 400 is substantially I-shaped. It shows a rear view. As shown in FIGS. 19E, 19F, 19G, and 19H, the width of the suction port forming portion 426 in the short direction of the connecting portion 431 formed by the rotating base portion 407, the rotating portion 408, and the like. It should be approximately the same or shorter than the width (width in the direction perpendicular to the axial direction). Further, the width of the suction port forming portion 426 in the short direction may be substantially equal to or shorter than the width of the rear joint 401 or the width of the front joint 402. Further, the width of the suction port forming portion 426 in the short direction may be substantially equal to or shorter than the maximum width of the connection pipe 300. Note that the maximum width of the connecting pipe 300 is formed in the connecting portion 305. As a result, when the suction tool 100 is engaged with the side surface of the extension pipe 13 and stored, the suction port forming portion 426 protrudes and does not get in the way, so that the storage property is improved. Further, the user rotates the suction port forming part 426 with respect to the front joint 402 so that the longitudinal direction of the suction port forming part 426 is along the axial direction of the rear joint 401 and the front joint 402, If the suction port forming portion 426 is substantially I-shaped, it is possible to clean a narrow gap that is deep inside. Further, the user rotates the suction port forming part 426 with respect to the front joint 402 so that the longitudinal direction of the suction port forming part 426 is perpendicular to the axial direction of the rear joint 401 and the front joint 402, If the suction mouth forming part 426 is rotated in a substantially T shape, the cleaning surface can be widened, and the number of times of back-and-forth can be increased because a large number of cleaning surfaces in the front-rear direction (front and back reciprocating directions) of the user can be taken. This can reduce the cleaning efficiency. Furthermore, since the width | variety of the longitudinal direction of the suction opening formation part 426 is shorter than the longitudinal direction of the suction body 14, the clearance gap which the suction body 14 does not enter can be cleaned. Further, since the friction surface in the left-right direction is smaller than that of the substantially I shape, the resistance is reduced, and the burden on the user's hand can be reduced.

後継手４０１の筒形状部４０６には、接続管３００のブレード体３０２の先端部にある抜け止め突起３０６を受ける穴部４２１がある。筒形状部４０６にブレード体３０２の先端部（接続部）が挿入され、抜け止め突起３０６が抜け止め突起３０６にはめ込まれることによって（ブレード体３０２の先端部の外側表面が筒形状部４０６の内側表面に当接することによって）、接続管３００と回動接続部４００とが接続される。これによって、使用者は、接続管３００と回動接続部４００とを容易に接続、分離することができる。   The tubular portion 406 of the rear joint 401 has a hole portion 421 that receives the retaining protrusion 306 at the tip of the blade body 302 of the connection pipe 300. The distal end portion (connecting portion) of the blade body 302 is inserted into the cylindrical portion 406 and the retaining projection 306 is fitted into the retaining projection 306 (the outer surface of the distal end portion of the blade body 302 is the inner side of the cylindrical portion 406). By abutting the surface), the connecting pipe 300 and the rotational connecting part 400 are connected. As a result, the user can easily connect and disconnect the connecting pipe 300 and the rotary connecting portion 400.

図２０に、吸口形成部４２６の分離時斜視図を示す。吸口形成部４２６の吸口面（開口面）には、本実施例のように、切り口部の端面に刷毛４２２を植毛することもでき、この刷毛４２２により、掃き、拭きといった掃除効果も得られる。刷毛４２２の形成方向は、吸口形成部４２６の吸口面の法線方向であってもよいし、吸口形成部４２６の吸口面の法線方向よりも外側に拡がっていてもよい。また、吸口形成部４２６を刷毛台４３８と吸口部４３７とに分割可能な構造とすることもできる。つまり、刷毛台４３８に複数の係合爪４３９を設け、係合爪４３９を吸口部４３７にはめ込むことによって、係合爪４３９を吸口部４３７に取り付けることができる。これによって、刷毛４２２の劣化、抜けなどあった際は刷毛台４３８だけを取替えることでよく、刷毛部のメンテナンス性をあげることができる。   In FIG. 20, the perspective view at the time of isolation | separation of the suction inlet formation part 426 is shown. The suction surface (opening surface) of the suction port forming portion 426 can also be planted with a brush 422 on the end surface of the cut portion as in this embodiment, and this brush 422 can also provide a cleaning effect such as sweeping and wiping. The direction in which the brush 422 is formed may be the normal direction of the suction surface of the suction port forming portion 426, or may extend outward from the normal direction of the suction surface of the suction port forming portion 426. Further, the suction port forming portion 426 can be structured to be divided into the brush bed 438 and the suction port portion 437. That is, the engaging claw 439 can be attached to the mouthpiece 437 by providing the brush table 438 with a plurality of engaging claws 439 and fitting the engaging claws 439 into the mouthpiece 437. As a result, when the brush 422 is deteriorated or missing, it is only necessary to replace the brush base 438, and the maintenance of the brush portion can be improved.

図２１に、先端側の回動接続部４００を手元操作部１２に接続した時の外観斜視図を示す。回動接続部４００の筒形状部４０６は、外側表面の上側と下側が手元操作部１２の接続部または延長管１３の内側表面に対応した形状、つまりＲ形状を有する係合部４４１を備える。係合部４４１の外側表面の上側と下側は、軸方向で回動ベース部４０７へ向かうに従って徐々に拡がっているのが好ましい。筒形状部４０６の係合部４４１よりも開口側の外形（外側表面の直径）は、係合部４４１の外形（外側表面の直径）よりも小さい。そして、回動接続部４００の筒形状部４０６が、後継手２０１の筒形状部２０５と同様に手元操作部１２の接続部または延長管１３の内側に挿入され、係合部４４１が手元操作部１２の接続部または延長管１３の内側表面に当接し、そして、手元操作部１２または延長管１３に設けられた着脱用クランプの抜け止め用の爪（図示せず）、筒形状部２０５に設けられた凹み部４４０にはめ込まれる。これによって、回動接続部４００と手元操作部１２または延長管１３とが接続される。接続管３００に接続することなく回動接続部４００を吸込具として使用することができるため、軽量で負担なく、机や高さの低い棚など身近な場所を容易に掃除することができる。   FIG. 21 is an external perspective view when the distal end side rotation connecting portion 400 is connected to the hand operating portion 12. The cylindrical shape portion 406 of the rotation connection portion 400 includes an engagement portion 441 having a shape in which the upper side and the lower side of the outer surface correspond to the connection portion of the hand operation portion 12 or the inner surface of the extension tube 13, that is, an R shape. It is preferable that the upper side and the lower side of the outer surface of the engaging portion 441 gradually expand toward the rotation base portion 407 in the axial direction. The outer shape (diameter of the outer surface) on the opening side of the engaging portion 441 of the cylindrical portion 406 is smaller than the outer shape (diameter of the outer surface) of the engaging portion 441. And the cylindrical part 406 of the rotation connection part 400 is inserted in the connection part of the hand operation part 12, or the inner side of the extension pipe 13 like the cylinder shape part 205 of the rear joint 201, and the engaging part 441 is a hand operation part. 12 is in contact with the inner surface of the connecting portion or the extension tube 13, and is provided in the cylindrical portion 205, and a claw (not shown) for retaining the detachable clamp provided in the hand operating portion 12 or the extension tube 13. It fits in the recessed part 440 made. As a result, the rotation connecting part 400 and the hand operating part 12 or the extension pipe 13 are connected. Since the rotation connecting portion 400 can be used as a suction tool without being connected to the connecting pipe 300, it is possible to easily clean a familiar place such as a desk or a low shelf without being burdened with light weight.

図９は接続管３００に回動接続部２００及び回動接続部４００を接続した状態を示す図である。図９では、回動接続部２００が接続管３００に接続された状態で接続管３００を下方に向けるように回動しており、さらに回動接続部４００が接続管３００に接続された状態で回動接続部４００の先端部が下方に向くように回動している。接続管３００の軸心上に対して吸口形成部４２６が下側にくる位置まで回動している。図９に示すように、手元側の回動接続部２００と中間の接続管３００と先端側の回動接続部４００はそれぞれの接続部で接続され、抜け止め突起により容易に外れなくなっている。手元側の回動接続部２００と先端側の回動接続部４００は、それぞれ回動角４５°回動させ、ノッチにより回動位置がある程度固定される。手元操作部１２に延長管１２の一端を接続し、延長管１２の他端に回動接続部２００を接続し、中間の接続管３００を最長に延長すると、図１０に示すように、例えば家具の上面や一般的な冷蔵庫の上面を掃除することができる。手元操作部１２は家具９００より低い位置にあり、これに接続される延長管１３の一端も家具９００より低い位置にあるが、延長管１３は他端（先端）は家具９００の上方に位置している。延長管１３は他端側が上を向くように傾斜した状態となっている。延長管１３の他端に接続される回動接続部２００は、これに接続される接続管３００が家具９００の上面に沿うように、下方に向けて回動している。この回動により、接続管３００は家具９００の上面を沿うような状態となる。さらに接続管３００に接続される回動接続部４００は、前継手４０２の先端部が家具９００の上面に向くように下方に向けて回動し、前継手４０２の先端部に設けられた刷毛４２２が家具９００の上面に接触する。これにより、家具の上面や一般的な冷蔵庫の上面を掃除することが可能となる。本実施例の場合、高さ寸法が１８００ｍｍ、奥行き寸法が６００ｍｍあるような家具９００においても、手元操作部１２を１２００ｍｍ程度の高さまで持ち上げると、家具９００の上面の奥まで容易に掃除を行うことができる。   FIG. 9 is a view showing a state in which the rotation connection unit 200 and the rotation connection unit 400 are connected to the connection pipe 300. In FIG. 9, the rotation connecting portion 200 is rotated so that the connection tube 300 is directed downward while the rotation connection portion 200 is connected to the connection tube 300, and the rotation connection portion 400 is further connected to the connection tube 300. It rotates so that the front-end | tip part of the rotation connection part 400 may face below. The suction port forming portion 426 rotates to a position below the axial center of the connection pipe 300. As shown in FIG. 9, the hand side rotation connecting portion 200, the intermediate connection pipe 300, and the tip end side rotation connecting portion 400 are connected by the respective connection portions and are not easily detached by the retaining protrusion. The rotation connection portion 200 on the hand side and the rotation connection portion 400 on the distal end side are rotated by a rotation angle of 45 °, and the rotation position is fixed to some extent by the notch. When one end of the extension pipe 12 is connected to the hand operation section 12, the rotation connection section 200 is connected to the other end of the extension pipe 12, and the intermediate connection pipe 300 is extended to the longest, as shown in FIG. You can clean the top surface of a refrigerator or the top surface of a typical refrigerator. The hand operating unit 12 is at a lower position than the furniture 900, and one end of the extension pipe 13 connected to the hand operating section 12 is also lower than the furniture 900, but the other end (tip) of the extension pipe 13 is located above the furniture 900. ing. The extension pipe 13 is inclined so that the other end side faces upward. The rotation connection part 200 connected to the other end of the extension pipe 13 is rotated downward so that the connection pipe 300 connected thereto is along the upper surface of the furniture 900. By this rotation, the connecting pipe 300 is brought into a state along the upper surface of the furniture 900. Further, the rotation connecting portion 400 connected to the connecting pipe 300 rotates downward so that the front end portion of the front joint 402 faces the upper surface of the furniture 900, and the brush 422 provided at the front end portion of the front joint 402. Contacts the upper surface of the furniture 900. Thereby, it becomes possible to clean the upper surface of furniture or the upper surface of a general refrigerator. In the case of the present embodiment, even in the furniture 900 having a height dimension of 1800 mm and a depth dimension of 600 mm, when the hand operation unit 12 is lifted to a height of about 1200 mm, the interior of the furniture 900 can be easily cleaned to the back. Can do.

本実施例においては、手元側の回動接続部２００と先端側の回動接続部４００といったように回動接続部を複数設けたことにより、手元操作部１２の高さ位置は高所の被掃除面よりも低い位置にあり、使用者の腕に掛かる負担は小さいのである。また、回動接続部間を伸縮可能としているので、奥行き寸法が短い高所にも対応するのである。ノッチは、ロックに比べロック解除の操作が不要であり、また、無理に力が掛かった場合、ロックではロック箇所が破損する恐れがあるのに対し、ノッチでは回動することで力が集中せず逃げるので破損の恐れは少ない。   In the present embodiment, by providing a plurality of rotation connection parts such as the rotation connection part 200 on the hand side and the rotation connection part 400 on the front end side, the height position of the hand operation part 12 is set at a high position. It is at a position lower than the cleaning surface, and the burden on the user's arm is small. Moreover, since the rotation connection part can be extended and contracted, it corresponds to a high place where the depth dimension is short. The notch requires no unlocking operation compared to the lock, and if the force is excessively applied, the lock part may be damaged by the lock, whereas the notch rotates to concentrate the force. Because it runs away, there is little risk of damage.

ここで、掃除機用の吸込具１００は、手元操作部１２の接続部にも接続可能であるから、延長管１３を接続せずに使用することもできる。また、接続方法は抜け止め突起による方法に限らず、ねじ接続やクランプ接続で構成して、強固な接続としてもよい。   Here, since the suction tool 100 for vacuum cleaners can be connected also to the connection part of the hand operation part 12, it can also be used without connecting the extension pipe | tube 13. FIG. Further, the connection method is not limited to the method using the retaining protrusions, and may be constituted by screw connection or clamp connection to provide a strong connection.

また、図１１に示すように、手元側の回動接続部２００と中間の接続管３００と先端側の回動接続部４００は、分離可能としてもよい。これらは、抜け止め突起で容易に外れないようになってはいるものの接続しないで使用することは可能であり、例えば先端側の回動接続部４００を接続しないようにすれば、先端側の回動接続部４００の幅では入らなかった狭い隙間にも到達することが可能となるし、また、手元側の回動接続部２００に短い吸込み口（図示せず）を接続すれば身近な所の掃除に適するのである。   Further, as shown in FIG. 11, the turning connection portion 200 on the hand side, the intermediate connecting pipe 300, and the turning connection portion 400 on the distal end side may be separable. These can be used without being connected although they are not easily detached by the retaining protrusions. For example, if the rotational connection portion 400 on the distal end side is not connected, the rotation on the distal end side can be performed. It is possible to reach a narrow gap that could not be entered with the width of the dynamic connecting portion 400, and it is also possible to connect a short suction port (not shown) to the rotating connecting portion 200 on the hand side. It is suitable for cleaning.

回動接続部４００は、接続管３００に接続された状態で刷毛４２２が下方側を向くような状態（図１，図９，図１０，図１１）の他に、図１２に示すように、接続管３００に接続された状態で刷毛４２２が上方側を向くような状態となるように、先端側の回動接続部４００を上下（左右）逆にして取り付けることができる。すなわち、回動接続部４００の回動方向が接続管３００に対して異なる方向に回動するように、回動接続部４００が接続管３００に着脱自在となっている。回動接続部４００を接続管３００に対して上下方向（左右方向）を逆に接続することにより、接続管３００に対する回動接続部４００の回動方向を異ならせることができ、掃除できる範囲が広がる。   In addition to the state in which the brush 422 faces downward (FIGS. 1, 9, 10, and 11) while being connected to the connecting pipe 300, the rotary connecting portion 400 is as shown in FIG. The rotation connecting portion 400 on the distal end side can be attached upside down (left and right) so that the brush 422 faces upward when connected to the connecting pipe 300. In other words, the rotation connection unit 400 is detachably attached to the connection tube 300 so that the rotation direction of the rotation connection unit 400 rotates in a different direction with respect to the connection tube 300. By connecting the rotation connecting portion 400 to the connection pipe 300 in the up-down direction (left-right direction), the rotation direction of the rotation connection portion 400 with respect to the connection pipe 300 can be varied, and there is a range that can be cleaned. spread.

本実施例では、接続管３００に接続された状態で刷毛４２２が上方側を向くようにすると、図１３に示すように、例えば天井８００など、掃除面が真下を向いた箇所も掃除することができ、しかも回動接続部間を伸縮可能としているので、家具９００などが邪魔をして延長管１３などが届かない、奥行きのある狭い空間の天井面でも掃除することができる。   In the present embodiment, when the brush 422 faces upward while being connected to the connecting pipe 300, as shown in FIG. 13, for example, a place where the cleaning surface faces directly below, such as the ceiling 800, can be cleaned. In addition, since it is possible to extend and contract between the rotating connection portions, it is possible to clean the ceiling surface of a narrow space with a deep space where the furniture 900 or the like gets in the way and the extension tube 13 does not reach.

手元操作部１２は天井８００より低い位置にあり、これに接続される延長管１３の一端も天井８００より低い位置にあるが、延長管１３は他端（先端）は天井８００の近くに位置している。延長管１３は他端側が上を向くように傾斜した状態となっている。延長管１３の他端に接続される回動接続部２００は、これに接続される接続管３００が天井８００に沿うように、下方に向けて回動している。この回動により、接続管３００は天井８００の下面を沿うような状態となる。さらに接続管３００に接続される回動接続部４００は、前継手４０２の先端部が天井８００を向くように上方に向けて回動し、前継手４０２の先端部に設けられた刷毛４２２が天井８００に接触する。これにより、天井８００を掃除することが可能となる。しかも家具９００の上方に位置する天井８００であっても、家具９００と干渉することなく、家具９００との接触を回避しつつ天井８００の掃除を行うことができる。本実施例の場合、高さ寸法が２２００ｍｍの天井８００においても、手元操作部１２を１４００ｍｍ程度の高さまで持ち上げると、天井８００の清掃を容易に掃除を行うことができる。   The hand operating unit 12 is at a position lower than the ceiling 800, and one end of the extension pipe 13 connected thereto is also at a position lower than the ceiling 800. However, the other end (tip) of the extension pipe 13 is located near the ceiling 800. ing. The extension pipe 13 is inclined so that the other end side faces upward. The rotation connection part 200 connected to the other end of the extension pipe 13 is rotated downward so that the connection pipe 300 connected thereto is along the ceiling 800. By this rotation, the connecting pipe 300 is brought into a state along the lower surface of the ceiling 800. Further, the rotation connecting portion 400 connected to the connecting pipe 300 rotates upward so that the front end portion of the front joint 402 faces the ceiling 800, and the brush 422 provided at the front end portion of the front joint 402 has a ceiling. Contact 800. As a result, the ceiling 800 can be cleaned. Moreover, even if the ceiling 800 is located above the furniture 900, the ceiling 800 can be cleaned while avoiding contact with the furniture 900 without interfering with the furniture 900. In the case of the present embodiment, even in the ceiling 800 having a height of 2200 mm, the ceiling 800 can be easily cleaned by lifting the hand operation unit 12 to a height of about 1400 mm.

また、本実施例では、図１４に示すように机１０００の下など、床面との空間が狭く、延長管１３の入らない奥行きのある隙間でも掃除することができる。この場合、接続管３００に接続される回動接続部２００を、図９，図１０，図１３に示す状態とは上下逆に回動するように取り付ける。図９，図１０，図１３においては、延長管１３に接続された回動接続部２００が、延長管１３に対して接続管３００を下方に回動するように接続している。図１４では、これとは逆に延長管１３に接続された回動接続部２００が、延長管１３に対して接続管３００を上方に回動するよう接続にしている。   Further, in this embodiment, as shown in FIG. 14, the space with the floor surface such as under the desk 1000 is narrow and can be cleaned even in a deep gap where the extension pipe 13 does not enter. In this case, the rotation connection part 200 connected to the connection pipe 300 is attached so as to rotate upside down with respect to the states shown in FIGS. 9, 10, and 13. In FIGS. 9, 10, and 13, the turning connection portion 200 connected to the extension pipe 13 is connected to the extension pipe 13 so as to turn the connection pipe 300 downward. In FIG. 14, conversely, the rotation connecting portion 200 connected to the extension pipe 13 is connected so as to rotate the connection pipe 300 upward with respect to the extension pipe 13.

手元操作部１２は机１０００より高い位置にあり、これに接続される延長管１３の一端も机１０００より高い位置にあるが、延長管１３は他端（先端）は下方の床面１２００近くに位置している。延長管１３は他端側が下を向くように傾斜した状態となっている。延長管１３の他端に接続される回動接続部２００は、これに接続される接続管３００が床面１２００に沿うように、延長管１３の軸方向に対して上方に向けて回動している。この回動により、接続管３００は床面１２００を沿うような状態となる。さらに接続管３００に接続される回動接続部４００は、前継手４０２の先端部が床面１２００を向くように下方に向けて回動し、前継手４０２の先端部に設けられた刷毛４２２が床面１２００に接触する。これにより、床面１２００を掃除することが可能となる。   The hand operating unit 12 is at a position higher than the desk 1000, and one end of the extension pipe 13 connected thereto is also higher than the desk 1000, but the other end (tip) of the extension pipe 13 is near the lower floor surface 1200. positioned. The extension pipe 13 is inclined so that the other end side faces downward. The rotation connecting portion 200 connected to the other end of the extension pipe 13 rotates upward with respect to the axial direction of the extension pipe 13 so that the connection pipe 300 connected thereto is along the floor surface 1200. ing. By this rotation, the connecting pipe 300 is brought into a state along the floor surface 1200. Further, the rotation connecting portion 400 connected to the connecting pipe 300 rotates downward so that the front end portion of the front joint 402 faces the floor surface 1200, and the brush 422 provided at the front end portion of the front joint 402 Contact the floor surface 1200. As a result, the floor surface 1200 can be cleaned.

また、図１２に示すように後継手２０１の筒形状部２０５、または回動接続部４００の筒形状部４０６を凹み部４４０で受ける形状ではなく、テーパ嵌合とすれば、抜け止め用の爪がない延長管や操作ハンドルにも接続することができ、専用の接続部品を必要としないことが可能である。   Further, as shown in FIG. 12, if the cylindrical portion 205 of the rear joint 201 or the cylindrical portion 406 of the rotation connecting portion 400 is not received by the recessed portion 440, but a taper fitting is used, a retaining claw is provided. It is possible to connect to an extension tube or an operation handle that does not have any special connection parts.

テーパ嵌合とした場合には、吸込具１００、または回動接続部４００を手元操作部１２、または延長管１３の他端側に上下逆に取り付けすることができる。この場合でも、上述した本実施例の効果を得ることができる。   In the case of taper fitting, the suction tool 100 or the rotation connecting portion 400 can be attached upside down to the other end side of the hand operating portion 12 or the extension tube 13. Even in this case, the effect of the present embodiment described above can be obtained.

以上のように本実施例によれば吸込具１００に回動連結部を複数設け、回動連結部の間に設けた接続管に対して回動連結部の少なくとも一方を接続管に対して上下逆に取り付け可能にしたので、家具などが邪魔をして延長管などが届かない、奥行きのある狭い空間の天井面でも掃除することができる。また、回動連結部（関節）間を伸縮自在としたので、さまざまな高所の奥行きに対応可能である。さらに、吸込具１００は手元操作部１２、または延長管１３の他端側に上下逆に取り付け可能にしたので、机の下など、床面との空間が狭く、延長管の入らない奥行きのある隙間でも掃除することができる。さらに、吸込具１００の先端の吸口形成部４２６を直接、手元操作部、または延長管の他端側に取り付け可能であり、略Ｔ字形状とすることで前後方向への掃除面を多くとることがで、左右方向へは摩擦面を減らすことができるため手元側への負担を減らすことができる。   As described above, according to the present embodiment, the suction tool 100 is provided with a plurality of rotation connection portions, and at least one of the rotation connection portions is vertically connected to the connection tube with respect to the connection tube provided between the rotation connection portions. On the other hand, because it can be attached, it can be cleaned even in the ceiling surface of a narrow space where the extension tube etc. does not reach because the furniture etc. gets in the way. In addition, since the rotation connecting portion (joint) can be expanded and contracted, it is possible to deal with various heights. Furthermore, since the suction tool 100 can be mounted upside down on the other end of the hand operating portion 12 or the extension pipe 13, the space with the floor surface, such as under a desk, is narrow and there is a depth that the extension pipe does not enter. It can be cleaned even in gaps. Furthermore, the suction port forming part 426 at the tip of the suction tool 100 can be directly attached to the hand operating part or the other end side of the extension pipe, and by taking a substantially T shape, a large cleaning surface in the front-rear direction can be taken. However, since the friction surface can be reduced in the left-right direction, the burden on the hand side can be reduced.
