Description

【０００１】
【発明の属する技術分野】
本発明は、本体にホース、延長管、吸込具を接続した状態で収納することができる電気掃除機に関し、特にその収納機構に関する。
【０００２】
【従来の技術】
従来、この種の電気掃除機としては図４に示すように、本体１０１に沿って延長管１０２を保持可能とすることにより、本体１０１にホース１０３、延長管１０２及び吸込具１０４を接続したまま、本体１０１をその後面を下にしてコンパクトに収納できるようにした電気掃除機が知られている。
【０００３】
この電気掃除機では、本体１０１の下面部前側に延長管１０２を着脱自在に保持する保持部１０５を設け、延長管１０２に保持部１０５と係合する係止部を設ける構成としていた。すなわち、本体１０１にホース１０３、延長管１０２、吸込具１０４を接続した状態で収納するとき、本体１０１の後面を下にして本体を立て、延長管１０２の係止部を本体１０１の保持部１０５に挿入していた。
【０００４】
【発明が解決しようとする課題】
前記従来の電気掃除機にあっては、本体１０１にホース１０３、延長管１０２、吸込具１０４を接続した状態で収納するとき、本体１０１の後面を下にして本体を立て、延長管１０２の係止部を本体１０１の保持部１０５に挿入していたので、収納状態で本体１０１が底面側に傾いたとき、吸込具１０４が床面にあたり押されて延長管１０２が保持部１０５から外れてしまうという問題があった。
【０００５】
本発明は前記従来の課題を解決するもので、収納状態のとき本体が傾いても収納状態を保持しつづけることができる電気掃除機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
前記従来の課題を解決するために、本発明の電気掃除機は、電動送風機を内蔵した本体と、前記電動送風機に連通し本体に接続するホースと、前記ホースに接続する延長管と、前記延長管に接続する吸込具を具備し、前記本体に前記ホース、前記延長管、および前記吸込具を接続した状態で、本体の後方部を接地させ、かつ前記本体の下面前方に設けた保持部と延長管に設けた係止部とを係合させ収納する電気掃除機において、収納状態のまま傾けた時、前記係止部を前記保持部から外れないように動作する防止手段を設け、前記防止手段は保持部近傍に設けた摺動自在の係合体とし、係止部に前記係合体と係合する被係合部を設け、前記係合体内部に球を内蔵する構成としたもので、収納状態のまま本体が傾いても係止部は保持部から外れないから、収納状態を保持しつづけることができる。
【０００７】
【発明の実施の形態】
請求項１に記載の発明は、電動送風機を内蔵した本体と、前記電動送風機に連通し本体に接続するホースと、前記ホースに接続する延長管と、前記延長管に接続する吸込具を具備し、前記本体に前記ホース、前記延長管、および前記吸込具を接続した状態で、本体の後方部を接地させ、かつ前記本体の下面前方に設けた保持部と延長管に設けた係止部とを係合させ収納する電気掃除機において、収納状態のまま傾けた時、前記係止部を前記保持部から外れないように動作する防止手段を設け、前記防止手段は保持部近傍に設けた摺動自在の係合体とし、係止部に前記係合体と係合する被係合部を設け、前記係合体の内部に球を備える構成としたので、収納状態で本体がその底面側に傾いたとき係合体の内部の球が係止部側に転がり係合体の端部に衝突することで係合体が係止部側に摺動し係止部と係合するから、収納状態で傾いたときのみ係合体は被係合部に係合し係止部は保持部から外れず収納状態を保持しつづけることができる。
【０００８】
請求項２に記載の発明は、請求項１に記載の係合体内部の底面を係止部側に対し、上方へ向かうようにしたもので、収納状態で本体がその底面側に傾いたとき係合体の内部の球が係止部側に転がり係合体の端部に衝突することで係合体が係止部側に摺動し係止部と係合するが、通常の収納状態に戻ったとき係合体内部の球は斜面を転がり、係止部と反対側の端部に衝突することで係合体が係止部と反対側に摺動するから、通常の収納状態では係止部は保持部と着脱自在になり、傾いたときのみ係合体は被係合部に係合し係止部は保持部から外れず収納状態を保持しつづけることができる。
【０００９】
【実施例】
以下本発明の実施例について図面を参照しながら説明する。
【００１０】
（実施例１）
図１は本発明の実施例１における電気掃除機の要部断面図であり、図２は同電気掃除機の外観斜視図である。
【００１１】
まず、電気掃除機の概略構成を図２にて説明する。１は電動送風機を内蔵し、前記電動送風機に連通する集塵室を設けた本体であり、２は集塵室に連通する吸込口に接続するホースであり、３はホース２に接続する延長管であり、４は延長管３に接続する吸込具４である。また、５は本体１の下面前側に設けた保持部であり、６は延長管３に設けた係止部である。そして、本体１にホース２、延長管３および吸込具４を接続した状態で、本体１の後方部１３を接地させ、かつ前記本体１の下面前方に設けた保持部５と延長管３に設けた係止部６とを係合させ、収納する構成となっている。
【００１２】
以下、本実施例の係合構成について図１を用いて説明する。図において、本体１の下面前側に設けた保持部５の溝に延長管３に設けた係止部６が係合するように構成されている。このとき保持部５の溝は２段構成とし、その上段に係止部６はずれ防止手段である略Ｌ字状の固定体７を回動自在に設ける構成としている。
【００１３】
この構成により、収納状態で本体がその底面側に傾いたとき、固定体７が回動しその端部が係止部６の上部に引っかかることで、係止部６を押さえ保持部５から外れなくなるので、収納状態のまま傾いても収納状態を保持しつづけることができる。
【００１４】
（実施例２）
図３は本発明の実施例２における電気掃除機の要部断面図である。なお、前記実施例と同一構成部品については同一符号を付して、その説明を省略する。
【００１５】
図３において、本体１の下面前側に保持部５を構成し、延長管３に係止部６を保持部５に係合するように設けている。保持部５の上部に摺動自在に設けた係止部６はずれ防止手段である係合体８を格納する格納室９を設け、係合体８は摺動するためのローラ１０を備えた構成としている。また、係合体８は中空とし、その内部には重量のある球１１を設けている。さらに、中空の内部底面は係止部６側に向かって水平面から次第に高くなるように傾斜を設けている。すなわち、中空の断面積は係止部側に向かって小さくなっている。また、係止部６には係合体８と対応する位置に係合体８と係合する被係合部１２を設けている。
【００１６】
以上のように構成された電気掃除機について、以下その動作作用を説明する。
【００１７】
収納状態で本体が底面側に傾いたとき球１１が係止部６側に転がり係合体８の端部に衝突することで係合体８が係止部６側に移動する。このとき、係合体８の上部に設けたローラ１０が格納室９の上側に沿って転がりながら摺動し被係合部１２と係合し係止部６は保持部５から外れなくなる。係合体８はローラ１０にガイドされるので係止部６と保持部５との係合は確実に行われる。そして、本体が通常の収納状態、すなわち垂直に戻されると、球１１は斜面を転がりその勢いで係合体８の係止部６と反対方向の端部に衝突することでローラが転がりながら係止部６と反対方向に摺動するので、係合体８は被係合部１２から外れる。このようにして、収納状態のまま傾いても収納状態を保持しつづけることができ、元に戻ると係止部を着脱自在にすることができる。
【００１８】
なお、本実施例では係合体を中空体とし、その中に重い球を入れる構成について説明したが、球を入れなくても係合体８と係止部６とを係合することができる。勿論このときは必ずしも中空とする必要はない。しかし、本実施例のように重い球の衝撃力を利用した方が速く係合状態にすることができ、確実に外れるのを防ぐことができる。
【００１９】
また、係合体８に傾斜を設けているが傾斜を設けなくても係合状態を外すことはできる。ただし、傾斜をつけ球を加速することにより、より速く係合状態を外すことができ利便性が良くなる。
【００２０】
【発明の効果】
以上のように、本発明によれば、収納状態のとき本体が傾いても収納状態を保持しつづけるようにすることができる。

Embodiments of the present invention will be described below with reference to the drawings.
[0010]
Example 1
FIG. 1 is a cross-sectional view of a main part of a vacuum cleaner according to Embodiment 1 of the present invention, and FIG. 2 is an external perspective view of the vacuum cleaner.
[0011]
First, a schematic configuration of the electric vacuum cleaner will be described with reference to FIG. Reference numeral 1 denotes a main body having a built-in electric blower and a dust collecting chamber communicating with the electric blower, 2 a hose connected to a suction port communicating with the dust collecting chamber, and 3 an extension pipe connected to the hose 2 4 is a suction tool 4 connected to the extension pipe 3. Reference numeral 5 denotes a holding portion provided on the front side of the lower surface of the main body 1, and 6 denotes a locking portion provided on the extension pipe 3. Then, with the hose 2, the extension pipe 3 and the suction tool 4 connected to the main body 1, the rear part 13 of the main body 1 is grounded, and the holding part 5 and the extension pipe 3 provided in front of the lower surface of the main body 1 are provided. The engaging portion 6 is engaged and stored.
[0012]
Hereinafter, the engagement configuration of the present embodiment will be described with reference to FIG. In the figure, the engaging portion 6 provided on the extension pipe 3 is engaged with the groove of the holding portion 5 provided on the lower surface front side of the main body 1. At this time, the groove of the holding portion 5 has a two-stage structure, and a substantially L-shaped fixing body 7 which is a means for preventing the locking portion 6 from being displaced is provided on the upper stage so as to be rotatable.
[0013]
With this configuration, when the main body is tilted to the bottom surface side in the storage state, the fixed body 7 is rotated and the end thereof is hooked on the upper portion of the locking portion 6, so that the locking portion 6 is detached from the pressing and holding portion 5. Therefore, the stored state can be maintained even if it is tilted in the stored state.
[0014]
(Example 2)
FIG. 3 is a cross-sectional view of a main part of the electric vacuum cleaner according to the second embodiment of the present invention. Note that the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0015]
In FIG. 3, a holding part 5 is configured on the front side of the lower surface of the main body 1, and a locking part 6 is provided on the extension pipe 3 so as to engage with the holding part 5. A locking portion 6 slidably provided on the upper portion of the holding portion 5 is provided with a storage chamber 9 for storing an engagement body 8 as a slip prevention means, and the engagement body 8 is provided with a roller 10 for sliding. . The engaging body 8 is hollow, and a heavy ball 11 is provided inside the engaging body 8. Further, the hollow inner bottom surface is inclined so as to gradually increase from the horizontal plane toward the locking portion 6 side. That is, the hollow cross-sectional area becomes smaller toward the locking portion side. The engaging portion 6 is provided with an engaged portion 12 that engages with the engaging body 8 at a position corresponding to the engaging body 8.
[0016]
About the vacuum cleaner comprised as mentioned above, the operation | movement effect | action is demonstrated below.
[0017]
When the main body is tilted toward the bottom surface in the stored state, the ball 11 rolls toward the locking portion 6 and collides with the end of the engaging body 8, whereby the engaging body 8 moves to the locking portion 6 side. At this time, the roller 10 provided on the upper portion of the engaging body 8 slides while rolling along the upper side of the storage chamber 9 and engages with the engaged portion 12 so that the locking portion 6 does not come off the holding portion 5. Since the engaging body 8 is guided by the roller 10, the engaging portion 6 and the holding portion 5 are reliably engaged. Then, when the main body is returned to the normal state, that is, when it is returned vertically, the ball 11 rolls on the inclined surface and collides with the end portion of the engaging body 8 opposite to the engaging portion 6 by the momentum so that the roller is locked while rolling. Since it slides in the opposite direction to the part 6, the engaging body 8 is disengaged from the engaged part 12. In this way, it is possible to keep the storage state even if it is tilted in the storage state, and when it returns to the original state, the locking portion can be made detachable.
[0018]
In the present embodiment, the configuration has been described in which the engaging body is a hollow body and a heavy sphere is placed therein. However, the engaging body 8 and the locking portion 6 can be engaged without the sphere. Of course, it is not always necessary to be hollow. However, the use of the impact force of a heavy sphere as in the present embodiment can be brought into an engaged state faster and can be reliably prevented from coming off.
[0019]
Moreover, although the engagement body 8 is provided with an inclination, the engagement state can be removed without providing the inclination. However, by increasing the inclination and accelerating the ball, the engaged state can be released more quickly, and convenience is improved.
[0020]
【The invention's effect】
As described above, according to the present invention, it is possible to keep the storage state even when the main body is tilted in the storage state.
