Description

【０００１】
【発明の属する技術分野】
本発明は手で把持することができる小型電気機器、殊に防水型の小型電気機器に関するものである。
【０００２】
【従来の技術】
ヘアカッターや電気かみそりのような小型電気機器では、電源部と駆動部とを直列に並べて筒状のハウジング内に収納した形態としたものが多く、この場合、ハウジングは一般に軸線が直線である筒状のものが用いられている。
【０００３】
しかし、電気かみそりの刃を肌に当てたり、ヘアカッターで髪や髭を切ったりする場合のハウジングの把持を考えると、ハウジングはその軸線が途中で折れ曲がったり曲線を描いたりしたもの、つまりは側面形状がくの字形になっている方が好ましい。
【０００４】
このような小型電気機器の一例が特開２００２−３６９９８１号公報（特許文献１）に示されている。側面形状がくの字形となっているハウジング内に電源部と駆動部とを収納し、更にハウジングの一端から斜め前方に突出するヘッド部を設けられている。
【０００５】
【特許文献１】
特開２００２−３６９９８１号公報
【０００６】
【発明が解決しようとする課題】
ところで、電気機器を防水型とする場合、この種の電気機器では、ハウジングの一端側に刃等の出力部を、他端側に充電器等との接続部を配置した形態となることから、ハウジングを両端が開口する筒状のものとし、一端側から電源部と駆動部とを一体化したモジュールを差し込み、その後、ハウジングの両端を閉じて防水型とするのが部品点数の点や組立の都合上、一般的である。
【０００７】
しかし、このような組立構造を取る場合、ハウジングの軸線の曲がり具合を大きくすると、一端側から電源部２と駆動部とを一体化したモジュールを差し込んで組み付けるということができなくなる。上記特許文献１に示されたものも、本来ならばヘッドとハウジングの下部とがなす角度でハウジングが途中で折れ曲がった形状とすることが理想であるにもかかわらず、上記の制約の点からハウジングの軸線の曲がり具合を小さく設定している。
【０００８】
ハウジングの内寸を上記モジュールよりかなり余裕のあるものとすることで電源部と駆動部とを一体化したモジュールの組み付けが可能となるが、この時にはハウジングの外形状も大きく（太く）なってしまう。つまり、把持しやすいように曲げ角度を大きくしようとすると、ハウジングが太くなってハウジングを握ることが難しくなる。
【０００９】
本発明はこのような点に鑑みなされたものであって、その目的とするところはハウジングが把持しやすい形状である上に、ハウジングが途中で大きく曲がっていることがハウジング内に内蔵する電源部と駆動部との組み付けに制限を与えてしまうことがない小型電気機器を提供するにある。
【００１０】
【課題を解決するための手段】
しかして本発明は、途中で屈曲した筒状のハウジングと、該ハウジングの一端寄りに納められる電源部と、上記ハウジングの他端寄りに納められる駆動部とを備え、相互間の電気的接続及び機械的連結が保たれているとともに筒状ハウジングの一端又は他端開口から筒状ハウジング内に挿入配設される電源部と駆動部とは、筒状ハウジングの屈曲方向において両者のなす角度が可変の状態で上記機械的連結がなされていることに第１の特徴を有している。機械的連結がなされた電源部と駆動部とを筒状で且つ途中で屈曲しているハウジングの一端開口からハウジング内に差し込む時、電源部と駆動部とのなす角度を変化させられるようにしたものである。
【００１１】
上記機械的連結は、電源部と駆動部の一方に設けられた回動軸と、他方に設けられて上記回動軸に回動自在に連結された軸受片とでなされていることが好ましい。
【００１２】
また、電源部と駆動部の少なくとも一方は、ハウジングに設けた係合部と係合して位置決めを行う位置決め部材を備えていてもよい。
【００１３】
また本発明は、途中で屈曲した筒状のハウジングと、該ハウジングの一端開口からハウジング内に挿入配置される電源部と、上記ハウジングの他端開口からハウジング内に挿入配置される駆動部とを備えて、ハウジング内において端面同士が突き合わされる電源部と駆動部は、その突き合わせ部に突き合わせ角度が可変の電気的接続用接触片を備えていることに他の特徴を有している。途中で屈曲した筒状のハウジングの両端開口から電源部と駆動部とを夫々差し込めば、ハウジング内において電源部と駆動部との電気的接続が接触片によってなされるようにしたものである。
【００１４】
【発明の実施の形態】
以下本発明を実施の形態の一例に基づいて詳述すると、図示例の小型電気機器は防水型のヘアカッターで、滑らかな曲面で外面が構成されているハウジング１は、図３に示す主ハウジング１１と、主ハウジング１１に組み合わされるカバー１２と、ヘアカット用の櫛刃状の刃３０を備えたヘッド部３とで構成されている。
【００１５】
また上記ハウジング１内には、二次電池で構成された電源部４と、モータを主体とする駆動部５とが配設されており、駆動部５におけるモータの回転はヘッド部３内において往復動に変換されて上記刃３０の駆動がなされる。
【００１６】
ここで、上記電源部４と駆動部５とは、側面形状がくの字形となっているハウジング１における主ハウジング１１に設けられた筒状部１３内に納められているのであるが、この筒状部１３も中程で屈曲した側面形状がくの字形となっており、筒上部１３の一端側に電源部４が、他端側に駆動部５が納められている。
【００１７】
ここにおいて、電源部４と駆動部５とは電気的に接続する必要があり、この接続をリード線４０で行う場合は、筒状部１３の一端開口から電源部４と駆動部５とを差し込んで組み付けることになるが、上述のように、筒状部１３は屈曲した形状となっている上に、電源部４と駆動部５も上記屈曲角度と同じ角度をなす状態で筒状部１３内に組み込まれることから、電源部４と駆動部５とを筒状部１３の屈曲角度と同じ角度で連結して一体化していた場合、筒状部１３の一端開口側から差し込んで組み込むことは困難であり、これを可能とするには筒状部１３の内径を電源部４や駆動部５の外径よりもかなり大きくして十分な余裕が生じるようにしておかなくてはならず、この時にはハウジング１が太くなってハウジング１が握りにくくなる。
【００１８】
このために電源部４の駆動部５側の端部に回動軸４５を設けるとともに、駆動部５の電源部４側の端部には上記回動軸４５を受ける軸受片５５を設けて、電源部４に対して駆動部５が回動自在となるように、つまりは電源部４と駆動部５との間の屈曲角度が可変となるようにしている。
【００１９】
図５に示すように、主ハウジング１の筒状部１３のヘッド部３側の一端開口から電源部４及び駆動部５を屈曲している筒状部１３内に差し込んで組み付けるにあたり、電源部４と駆動部５とがなす角度を変更しながら差し込むことができるものであり、この場合、電源部４と駆動部５との外寸に対する筒状部１３の内寸の余裕が小さくとも、電源部４と駆動部５とを筒状部１３内に納めることができ、さらに筒状部１３への差し込みが完了した時点で電源部４と駆動部５とがなす角度をさらに調整することで、電源部４及び駆動部５の筒状部１３内の所定位置へのビスなどによる固定を行うことができる。駆動部５に設けた一対の固定部５４は駆動部５を主ハウジング１１にビス止め固定するためのものである。
【００２０】
図６及び図７に示すように、電源部４から係合軸４６を突出させておくとともに、図８に示すように、筒状部１３内に上記係合軸４６を受ける係合溝１６を設けておき、筒状部１３の一端開口から電源部４を差し込んだ時、係合軸４６が係合溝１６に係合して電源部４が位置決めされるようにしてもよい。この場合、主ハウジング１１の筒状部１３内面との間のクリアランスが大きくなっている電源部４の位置決めを係合溝１６に係合した係合軸４６を基準に行うことができるために、電源部４の位置決め固定が容易となる。また、係合軸４６と係合溝１６との係合部と、前記固定部５４による固定とで駆動部５は位置決め固定されることなり、駆動部５のより確実な固定を行うことができる。
【００２１】
図９は電源部４と駆動部５とが回動自在に連結されて屈曲角度が可変となっていることから、筒状部１３の屈曲角度が異なっている他のハウジング１にも組み付けることができることを示している。
【００２２】
図１０及び図１１に他の実施の形態の一例を示す。ここでは電源部４の駆動部５側の端面に板ばね状の接触片４７を設けるとともに、駆動部５の電源部４側の端面に上記接触片４７に接触する接触片５７を突設している。この時、電源部４と駆動部５とがなす角度が少々大きくても両接触片４７，５７間の接続が保たれるように接触片４７，５７の形状を定めている。
【００２３】
そして、本例の場合、ハウジング１の筒状部１３内への電源部４と駆動部５との組み付けは、筒状部１３の一端開口側から駆動部５を差し込み、他端開口側から電源部４を差し込んで、筒状部１３内において電源部４と駆動部５とを突き合わせて上記接触片４７，５７による両者間の電気的接続がなされるようにしている。
【００２４】
この場合、電源部４や駆動部５の組み付け時の向きの変化を考慮しなくてもよいために筒状部１３の内寸を最小にすることができ、この結果、ハウジング１の外形寸法を小さくすることができる。
【００２５】
【発明の効果】
以上のように本発明においては、途中で屈曲した筒状のハウジングと、該ハウジングの一端寄りに納められる電源部と、上記ハウジングの他端寄りに納められる駆動部とを備え、相互間の電気的接続及び機械的連結が保たれているとともに筒状ハウジングの一端又は他端開口から筒状ハウジング内に挿入配設される電源部と駆動部とは、筒状ハウジングの屈曲方向において両者のなす角度が可変の状態で上記機械的連結がなされていることから、機械的連結がなされた電源部と駆動部とを筒状で且つ途中で屈曲しているハウジングの一端開口からハウジング内に差し込む時、電源部と駆動部とのなす角度を変化させることができるものであり、このために途中で屈曲している筒状のハウジングの屈曲角度が大きくても、電源部と駆動部とをハウジングの一端開口側から差し込んで組み付けることができるとともに、電源部や駆動部外寸に対してハウジングの内寸をさほど大きくしなくても組み付けに問題が生じることがないものであり、この結果、ハウジングが把持しやすい屈曲角度及び太さの小型電気機器を提供することができる。
【００２６】
上記機械的連結は、電源部と駆動部の一方に設けられた回動軸と、他方に設けられて上記回動軸に回動自在に連結された軸受片とでなされていることが、組立性及び信頼性の点で好ましい。
【００２７】
また、電源部と駆動部の少なくとも一方は、ハウジングに設けた係合部と係合して位置決めを行う位置決め部材を備えていると、ハウジング内における電源部や駆動部の位置決め固定が容易となる。
【００２８】
また、途中で屈曲した筒状のハウジングと、該ハウジングの一端開口からハウジング内に挿入配置される電源部と、上記ハウジングの他端開口からハウジング内に挿入配置される駆動部とを備えて、ハウジング内において端面同士が突き合わされる電源部と駆動部は、その突き合わせ部に突き合わせ角度が可変の電気的接続用接触片を備えたものにおいては、途中で屈曲した筒状のハウジングの両端開口から電源部と駆動部とを夫々差し込めば、ハウジング内において電源部と駆動部との電気的接続が接触片によってなされるものであり、筒状のハウジングの屈曲角度に関係なく電源部と駆動部とを確実に且つ容易に組み付けることができる上に、ハウジングの内寸と電源部及び駆動部の外寸との差を小さくしても組み付けに問題が生じることがなくて、より細身で握りやすいハウジングとすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a small electric device that can be held by hand, and more particularly to a waterproof small electric device.
[0002]
[Prior art]
Many small electric devices such as hair cutters and electric razors have a configuration in which a power supply unit and a drive unit are arranged in series and housed in a cylindrical housing. In this case, the housing is generally a cylinder whose axis is a straight line. The shape is used.
[0003]
However, considering the gripping of the housing when the blade of an electric razor is applied to the skin or when cutting hair or wrinkles with a hair cutter, the housing is bent or curved in the middle, that is, the side It is preferable that the shape is a square shape.
[0004]
An example of such a small electric device is disclosed in Japanese Patent Laid-Open No. 2002-369981 (Patent Document 1). A power supply unit and a drive unit are housed in a housing whose side surface has a dogleg shape, and a head unit that projects obliquely forward from one end of the housing is provided.
[0005]
[Patent Document 1]
Japanese Patent Laid-Open No. 2002-369981
[Problems to be solved by the invention]
By the way, when the electrical equipment is a waterproof type, in this type of electrical equipment, since the output portion such as a blade is disposed on one end side of the housing, and the connection portion with a charger or the like is disposed on the other end side, The housing has a cylindrical shape with both ends open, and a module that integrates the power supply unit and the drive unit is inserted from one end, and then both ends of the housing are closed to make it waterproof. General for convenience.
[0007]
However, when such an assembly structure is adopted, if the bending of the axis of the housing is increased, it becomes impossible to insert and assemble a module in which the power supply unit 2 and the drive unit are integrated from one end side. Although the one disclosed in Patent Document 1 is also ideal in that the housing is bent in the middle at an angle formed by the head and the lower portion of the housing, the housing is considered in view of the above limitations. The bending degree of the axis is set small.
[0008]
By making the inner dimension of the housing much larger than that of the above module, it is possible to assemble a module that integrates the power supply unit and the drive unit, but at this time the outer shape of the housing also becomes larger (thicker) . That is, if the bending angle is increased so as to be easily gripped, the housing becomes thick and it is difficult to grip the housing.
[0009]
The present invention has been made in view of these points, and the object of the present invention is that the housing has a shape that is easy to grip, and that the housing is bent halfway along the way. The present invention provides a small electric device that does not limit the assembly of the motor and the drive unit.
[0010]
[Means for Solving the Problems]
Thus, the present invention includes a cylindrical housing bent halfway, a power supply unit housed near one end of the housing, and a drive unit housed near the other end of the housing, The mechanical connection is maintained and the angle between the power supply unit and the drive unit inserted into the cylindrical housing from one end or the other end opening of the cylindrical housing is variable in the bending direction of the cylindrical housing. The first feature is that the above-mentioned mechanical connection is made in this state. When the mechanically connected power supply unit and drive unit are inserted into the housing through one end opening of the housing that is bent in the middle of the tube, the angle formed between the power supply unit and the drive unit can be changed. Is.
[0011]
The mechanical connection is preferably made up of a rotation shaft provided on one of the power supply unit and the drive unit, and a bearing piece provided on the other and rotatably connected to the rotation shaft.
[0012]
Further, at least one of the power supply unit and the drive unit may include a positioning member that performs positioning by engaging with an engaging portion provided in the housing.
[0013]
The present invention also includes a cylindrical housing bent halfway, a power supply unit inserted and arranged in the housing from one end opening of the housing, and a drive unit inserted and arranged in the housing from the other end opening of the housing. In addition, the power supply unit and the drive unit, whose end faces are butted in the housing, have another feature in that the butting portion includes a contact piece for electrical connection whose abutting angle is variable. If the power supply unit and the drive unit are respectively inserted from both end openings of the cylindrical housing bent in the middle, the electrical connection between the power supply unit and the drive unit is made by the contact piece in the housing.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on an example of an embodiment. A small electric device in the illustrated example is a waterproof hair cutter, and a housing 1 whose outer surface is configured by a smooth curved surface is a main housing shown in FIG. 11, a cover 12 combined with the main housing 11, and a head portion 3 having a comb-like blade 30 for hair cutting.
[0015]
In the housing 1, a power supply unit 4 composed of a secondary battery and a drive unit 5 mainly composed of a motor are disposed, and the rotation of the motor in the drive unit 5 reciprocates in the head unit 3. The blade 30 is driven after being converted into motion.
[0016]
Here, the power supply unit 4 and the drive unit 5 are housed in a cylindrical part 13 provided in the main housing 11 of the housing 1 whose side shape is a U-shape. The side portion of the portion 13 bent in the middle has a dogleg shape, and the power source portion 4 is housed on one end side of the cylinder upper portion 13 and the drive portion 5 is housed on the other end side.
[0017]
Here, the power supply unit 4 and the drive unit 5 need to be electrically connected. When this connection is made by the lead wire 40, the power supply unit 4 and the drive unit 5 are inserted from one end opening of the cylindrical portion 13. As described above, the cylindrical portion 13 has a bent shape, and the power source portion 4 and the drive portion 5 also have the same angle as the bending angle. Therefore, when the power supply unit 4 and the drive unit 5 are connected and integrated at the same angle as the bending angle of the cylindrical part 13, it is difficult to insert the power source part 4 and the driving part 5 from one end opening side of the cylindrical part 13 and integrate them. In order to make this possible, it is necessary to make the inner diameter of the cylindrical portion 13 considerably larger than the outer diameter of the power source section 4 and the driving section 5 so that a sufficient margin is generated. The housing 1 becomes thick and the housing 1 becomes difficult to grip.
[0018]
For this purpose, a rotation shaft 45 is provided at the end of the power supply unit 4 on the drive unit 5 side, and a bearing piece 55 for receiving the rotation shaft 45 is provided at the end of the drive unit 5 on the power supply unit 4 side. The bend angle between the power supply unit 4 and the drive unit 5 is made variable so that the drive unit 5 can rotate with respect to the power supply unit 4.
[0019]
As shown in FIG. 5, when the power supply unit 4 and the drive unit 5 are inserted into the bent cylindrical part 13 from the one end opening on the head part 3 side of the cylindrical part 13 of the main housing 1 and assembled, And the drive unit 5 can be inserted while changing the angle. In this case, even if the inner dimension of the cylindrical part 13 with respect to the outer dimension of the power supply unit 4 and the drive unit 5 is small, the power supply unit 4 and the drive unit 5 can be accommodated in the cylindrical part 13, and when the insertion into the cylindrical part 13 is completed, the angle formed between the power supply unit 4 and the drive unit 5 is further adjusted, thereby The fixing to a predetermined position in the cylindrical portion 13 of the portion 4 and the driving portion 5 can be performed by screws or the like. A pair of fixing portions 54 provided in the driving portion 5 are for fixing the driving portion 5 to the main housing 11 with screws.
[0020]
As shown in FIGS. 6 and 7, the engaging shaft 46 protrudes from the power supply unit 4, and the engaging groove 16 that receives the engaging shaft 46 is formed in the cylindrical portion 13 as shown in FIG. 8. It may be provided that when the power supply unit 4 is inserted from the one end opening of the cylindrical portion 13, the engaging shaft 46 engages with the engagement groove 16 to position the power supply unit 4. In this case, since the positioning of the power supply unit 4 having a large clearance with the inner surface of the cylindrical portion 13 of the main housing 11 can be performed with reference to the engagement shaft 46 engaged with the engagement groove 16, The positioning and fixing of the power supply unit 4 is facilitated. Further, the drive portion 5 is positioned and fixed by the engagement portion between the engagement shaft 46 and the engagement groove 16 and the fixation by the fixing portion 54, so that the drive portion 5 can be more reliably fixed. .
[0021]
In FIG. 9, since the power supply unit 4 and the drive unit 5 are pivotably connected and the bending angle is variable, the cylindrical unit 13 can be assembled to another housing 1 having a different bending angle. It shows what you can do.
[0022]
An example of another embodiment is shown in FIGS. Here, a leaf spring-like contact piece 47 is provided on the end surface of the power supply unit 4 on the drive unit 5 side, and a contact piece 57 that contacts the contact piece 47 is provided on the end surface of the drive unit 5 on the power supply unit 4 side. Yes. At this time, the shapes of the contact pieces 47 and 57 are determined so that the connection between the contact pieces 47 and 57 is maintained even if the angle formed by the power supply unit 4 and the drive unit 5 is slightly large.
[0023]
In the case of this example, the power supply unit 4 and the drive unit 5 are assembled into the cylindrical part 13 of the housing 1 by inserting the drive part 5 from one end opening side of the cylindrical part 13 and power from the other end opening side. The power supply unit 4 and the drive unit 5 are brought into contact with each other in the cylindrical unit 13 by inserting the unit 4 so that the contact pieces 47 and 57 are electrically connected to each other.
[0024]
In this case, since it is not necessary to consider the change in orientation when the power supply unit 4 and the drive unit 5 are assembled, the inner dimension of the cylindrical part 13 can be minimized, and as a result, the outer dimension of the housing 1 can be reduced. Can be small.

【The invention's effect】
As described above, the present invention includes a cylindrical housing that is bent halfway, a power supply unit that is housed near one end of the housing, and a drive unit that is housed near the other end of the housing. The power supply unit and the drive unit that are inserted and arranged in the cylindrical housing from one end or the other end opening of the cylindrical housing are maintained in the bending direction of the cylindrical housing. When the mechanical connection is made in a state where the angle is variable, the power supply unit and the drive unit that have been mechanically connected are inserted into the housing from one end opening of the housing that is cylindrical and bent in the middle. The angle between the power supply unit and the drive unit can be changed. For this reason, even if the bending angle of the cylindrical housing bent in the middle is large, the power supply unit and the drive unit can be separated from each other. As well as being able to be inserted and assembled from one end opening side of the ging, there is no problem in assembling even if the inner dimension of the housing is not so large with respect to the outer dimension of the power supply part and the driving part. It is possible to provide a small electric device having a bending angle and a thickness that can be easily held by the housing.
