Description

本発明は、作動中に振動を発生する手工具装置、特に、電動ドリルハンマー、チゼル装置、打撃穿孔装置、特に回し引き鋸や片刃鋸のようなモータ駆動鋸装置、または切断装置もしくは特に、面取り装置のような研削装置、などの手工具装置に関するものである。これらの手工具装置は、駆動モータを収納する主ハウジングと、把手ハウジングとを有する。把手ハウジングは、主ハウジングに対し少なくとも１個の空間方向内に制限された範囲において移動可能に保持する。さらに、把手ハウジングには、押しボタンによって操作可能であり、配線によって駆動モータを電気的に接続したモータスイッチを設ける。   The present invention relates to hand tool devices that generate vibrations during operation, in particular electric drill hammers, chisel devices, impact drilling devices, in particular motor driven saw devices such as rotary saws and single-edged saws, or cutting devices or in particular chamfering. The present invention relates to a hand tool device such as a grinding device. These hand tool devices have a main housing that houses a drive motor and a handle housing. The handle housing is held so as to be movable within a range limited to at least one space direction with respect to the main housing. Further, the handle housing is provided with a motor switch that can be operated by a push button and electrically connected to a drive motor by wiring.

把手ハウジングの主ハウジングに対して相対移動できることから、このような手工具装置には防振装置を設けることがある。このような防振装置は、ばね手段、緩衝手段として形成し、前述した双方のハウジング間に作用させる。このようにして、作動中に主ハウジングに生じる振動が把手ハウジングに伝わるのを劇的に減少する。   Such a hand tool device may be provided with an anti-vibration device because it can move relative to the main housing of the handle housing. Such an anti-vibration device is formed as a spring means and a buffer means, and acts between both housings described above. In this way, the vibrations that occur in the main housing during operation are transmitted to the handle housing dramatically.

特許文献１は、工具装置のための、把手ハウジングと主ハウジングとの連結領域において作用する防振装置を記載している。連結領域において、主ハウジングは２個の支持開口部を有し、これら開口部からはそれぞれ摺動可能な連結素子を突出させる。双方の連結素子は、それぞれ、一方の端部を把手ハウジングに、他方の端部をばね力に抗して回動可能な支持装置に、連結する。把手ハウジングは、このようにしてばね力に抗して、主ハウジングに対して摺動可能に保持する。この場合、把手ハウジングには、複数の素線によって主ハウジング内のモータに電気的に接続したスイッチを収納する。配線は、一方の支持開口部を経て案内する。
欧州特許出願公開第１５２９６０２号明細書 Patent Document 1 describes a vibration isolator for a tool device that acts in a connection region between a handle housing and a main housing. In the connection area, the main housing has two support openings from which the slidable connection elements project. Both of the connecting elements are connected to a handle housing at one end and to a support device that can rotate against the spring force at the other end. The handle housing is thus slidably held with respect to the main housing against the spring force. In this case, the handle housing houses a switch electrically connected to the motor in the main housing by a plurality of strands. The wiring is guided through one support opening.
European Patent Application No. 1529602

この従来の工具装置の欠点は、連結領域内の素線は、互いに、またハウジング部に対し、ゆるく固定される点が挙げられる。作動中の振動により発生する、把手ハウジングと主ハウジングとの相対的な運動によって、素線相互の、また素線のハウジングに対する相対的な運動を生ずる。これらの相対的な運動が原因で、素線が引っ掛かって動かなくなる、または素線相互、もしくは素線とハウジングとが擦れ易くなる。この構成では、特にハウジング内に穿孔屑が存在する場合、短期間で配線の損傷を生じ、工具装置の故障につながる恐れがある。   The disadvantage of this conventional tool device is that the strands in the connecting area are loosely fixed to each other and to the housing part. The relative movement between the handle housing and the main housing caused by the vibration during operation causes the movement of the strands relative to each other and of the strands relative to the housing. Because of these relative movements, the strands are caught and become unmovable, or the strands tend to rub against each other or between the strands and the housing. With this configuration, particularly when drilling waste exists in the housing, the wiring may be damaged in a short period of time, which may lead to failure of the tool device.

したがって、本発明の課題は、主ハウジングに対し防振対策を施した、モータスイッチ付きの把手ハウジングを設けた工具装置において、上述の欠点を回避し、配線を損傷から保護するにある。   Accordingly, an object of the present invention is to avoid the above-mentioned drawbacks and protect the wiring from damage in a tool device provided with a handle housing with a motor switch, which is provided with anti-vibration measures for the main housing.

この課題を解決するため本発明は、配線に発泡保護カバーを設けたことを特徴とする。   In order to solve this problem, the present invention is characterized in that a foam protective cover is provided on the wiring.

このような発泡素材の保護カバーにより、摩擦による素線の損傷を効果的に防ぐことが可能となり、さらに保護カバーに剛性を持たせることで、作動中に相対移動する２個のハウジング部分の間に配線が引っ掛かり動かなくなるのを防ぐことができる。   Such a protective cover made of foam material can effectively prevent damage to the strands due to friction, and by providing rigidity to the protective cover, the two cover parts move relatively during operation. It is possible to prevent the wires from getting stuck and moving.

本発明の特に好適な実施の形態においては、配線は、少なくとも２本の平行に配置した素線を有するものとし、これら素線を保護カバー内に埋設し、保護カバーの中で、互いに可能な限り離して固定する。この構成により、素線相互の摩擦、及びこれに由来する損傷を防ぐことができる。さらにはこの構成により、２本以上の素線を同時に扱うことが可能となり、工具装置内での配線の組み付けが極めて簡単となる。   In a particularly preferred embodiment of the present invention, the wiring has at least two parallel-arranged strands, and these strands are embedded in the protective cover and can be mutually connected in the protective cover. Fix as far as possible. With this configuration, it is possible to prevent friction between the strands and damage resulting therefrom. Furthermore, this configuration makes it possible to handle two or more strands at the same time, and the assembly of the wiring in the tool device becomes extremely simple.

この場合、さらに、平行に配置した保護カバー内の素線を互いに離して固定する。この構成により、大きな負荷の下でも、素線相互の摩擦及び、これに由来する素線の損傷を回避できる。   In this case, the strands in the protective cover arranged in parallel are further fixed apart from each other. With this configuration, it is possible to avoid friction between the strands and damage to the strands resulting therefrom even under a large load.

本発明の好適な実施の形態においては、保護カバーに伸張可能な曲折部をすくなくとも１個設ける。伸張可能とは、曲折部の少なくとも一部分において、保護カバーが工具装置のいかなる素子にも触れていないことを意味する。このような伸張可能な曲折部により、配線を組み込んだ状態においても、保護カバーあるいは素線の長い遊びが得られる。これにより、例えば作動中の、把手ハウジングと主ハウジングとの相対的な運動により発生する、接続領域と、電気的もしくは電子的素子との間の距離変化を、より吸収しやすくなる。このようにして、素線もしくは素線の電気的接続が損傷する危険性をより効果的に回避することができる。さらに、この長い遊びによって、当該の接続領域または、他の接続領域もしくは他の素子に対する当該素子も移動でき、例えば、修理や組立の際に、掴みやすくなる。   In a preferred embodiment of the present invention, at least one bendable portion that can be extended is provided in the protective cover. Stretchable means that the protective cover does not touch any element of the tooling device in at least a portion of the bend. Due to such an extendable bent portion, a long play of the protective cover or the strand can be obtained even when the wiring is incorporated. This makes it easier to absorb changes in the distance between the connection area and the electrical or electronic element, for example caused by the relative movement of the handle housing and the main housing during operation. In this way, it is possible to more effectively avoid the risk of damaging the strands or the electrical connection of the strands. Furthermore, this long play allows the connection area or the connection area to be connected to other connection areas or other elements, for example, to facilitate gripping during repair or assembly.

本発明の好適な実施の形態においては、保護カバー内の、配線に接続する電気的、もしくは電子的な少なくとも１個の構成素子を発泡材に埋設する。この構成により、配線と同時に、例えばコンデンサのような、電気的もしくは電子的な構成部品を、作動中に発生する振動や打撃による損傷から効果的に保護することができる。さらに、この構成により、保護カバーの一定の剛性の下で特に簡単な組立構成が実現可能となる。これにより、例えば他の工具装置とは別に生産し、最終組立段階において初めて組み入れることができる。   In a preferred embodiment of the present invention, at least one electrical or electronic component connected to the wiring in the protective cover is embedded in the foam material. With this configuration, at the same time as the wiring, it is possible to effectively protect, for example, electrical or electronic components such as a capacitor from vibrations or damage caused by impact generated during operation. Furthermore, this configuration makes it possible to realize a particularly simple assembly configuration under a certain rigidity of the protective cover. Thereby, for example, it can be produced separately from other tool devices and incorporated for the first time in the final assembly stage.

本発明の好適な実施の形態においては、ハウジングに固定した収容手段に連結できる係止体を保護カバーにより構成する。この構成により、保護カバーは、配線、および必要であれば発泡材で包囲した他の技術的もしくは電子的構成部品と一緒に、迅速かつ確実に工具装置の中に設置できる。この場合、保護カバーは、正確に位置決めすることができ、これにより、ハウジングで発生する相対的な運動を補償する十分な運動の自由度が、摩擦による破損なしに保証される。   In a preferred embodiment of the present invention, the locking body that can be connected to the receiving means fixed to the housing is constituted by a protective cover. With this arrangement, the protective cover can be quickly and reliably installed in the tooling device together with the wiring and, if necessary, other technical or electronic components surrounded by foam. In this case, the protective cover can be accurately positioned, thereby ensuring sufficient freedom of movement to compensate for the relative movement occurring in the housing, without damage due to friction.

本発明の特に好適な実施の形態においては、保護カバーは熱硬化性発泡ポリウレタン製とする。この構成により、より簡単生産製造で、高い耐摩耗性とともに、十分な可撓性が保証される。
以下、図面につき本発明の好適な実施例を説明する。 In a particularly preferred embodiment of the invention, the protective cover is made of a thermosetting foamed polyurethane. This configuration ensures sufficient flexibility with high wear resistance and simpler production.
Preferred embodiments of the present invention will be described below with reference to the drawings.

図１には、２部分構成のハウジング４を有する、チゼル装置の形式の電動手工具装置２を示す。この電動手工具装置２には、ばねとして示した防振装置８を介して主ハウジング１０に取り付けた把手ハウジング６を設ける。この場合、この防振装置８は、ばね弾性手段または緩衝手段、もしくはこれら双方の組み合わせにより構成することができる。どの場合にも、把手ハウジング６は、主ハウジング１０に対して、第１空間方向Ｈに沿って、手工具装置の作動方向Ａに平行に、制限された範囲で移動可能に保持する。さらに、把手ハウジング６は、主ハウジング１０に対して、第１空間方向Ｈに対して直交する方向の一方向もしくは両方向である空間方向にも限定的に移動可能に保持する。   FIG. 1 shows an electric hand tool device 2 in the form of a chisel device having a two-part housing 4. The electric hand tool device 2 is provided with a handle housing 6 attached to the main housing 10 via a vibration isolator 8 shown as a spring. In this case, the vibration isolator 8 can be constituted by a spring elastic means, a buffer means, or a combination of both. In any case, the handle housing 6 is held with respect to the main housing 10 so as to be movable in a limited range along the first space direction H in parallel with the operation direction A of the hand tool device. Furthermore, the handle housing 6 holds the main housing 10 movably in a limited direction in one or both directions perpendicular to the first spatial direction H.

主ハウジング１０内には手工具装置２の駆動モータ１２を収納する。この駆動モータ１２は、調整及び表示電子機器としての電子機器１８のモータスイッチ１６を有し、全体的に参照符号１４で示す配線によって、把手ハウジング６に保持した公衆網電源ケーブル２０及びコンデンサ２２に電気的に接続する。さらに、配線１４には、把手ハウジング６と主ハウジング１０との間の電気的接続を行う接続線束２４を設ける。   A drive motor 12 of the hand tool device 2 is accommodated in the main housing 10. This drive motor 12 has a motor switch 16 of an electronic device 18 as an adjustment and display electronic device, and is connected to a public network power cable 20 and a capacitor 22 held in the handle housing 6 by wiring generally indicated by reference numeral 14. Connect electrically. Further, the wiring 14 is provided with a connecting wire bundle 24 that performs electrical connection between the handle housing 6 and the main housing 10.

図２に示すように、配線１４にはケーブルハーネス２６を設ける。このケーブルハーネス２６は、複数の素線２８によって、駆動モータ１２もしくは駆動モータ１２の（図示しない）パワー電子機器に電気的に接続するモータ接続線３０、モータスイッチ１６に電気的に接続するスイッチ接続線３２、電子機器１８に電気的に接続する電子機器接続線３４、公衆網電源ケーブル２０に電気的に接続する公衆網接続線３６、ならびに、コンデンサ２２を、互いに電気的に接続する。この際、素線２８はその長さの大部分を熱硬化性発泡ポリウレタン製保護カバー３８で覆う。さらに、コンデンサ２２も保護カバー３８内に埋設する。このようにして、素線２８およびコンデンサを、把手ハウジング６との摩擦による破損から保護できる。さらに、保護カバー３８は剛性を有し、この剛性により、組み立ておよび修理におけるケーブルハーネス２６の取り扱いが容易となる。   As shown in FIG. 2, a cable harness 26 is provided in the wiring 14. The cable harness 26 is connected to a drive motor 12 or a power electronic device (not shown) of the drive motor 12 by a plurality of strands 28 and a switch connection electrically connected to the motor switch 16. The line 32, the electronic device connection line 34 electrically connected to the electronic device 18, the public network connection line 36 electrically connected to the public network power cable 20, and the capacitor 22 are electrically connected to each other. At this time, most of the length of the strand 28 is covered with a thermosetting foamed polyurethane protective cover 38. Furthermore, the capacitor 22 is also embedded in the protective cover 38. In this way, the wire 28 and the capacitor can be protected from damage due to friction with the handle housing 6. Furthermore, the protective cover 38 has rigidity, and this rigidity facilitates handling of the cable harness 26 in assembly and repair.

このとき用いる発泡ポリウレタンには、化学変化中発泡に必要な活性剤を添加する。さらには、所定領域を活性剤なしで、またその結果構成をコンパクトにするために、促進剤を個別に添加する方法も考えられる。この構成により、例えば、特に電子機器１８の収納部を保護カバー２８と一体にできる。   An activator necessary for foaming is added to the foamed polyurethane used at this time during chemical change. Furthermore, it is also conceivable to add accelerators individually in order to make certain areas without activators and consequently compact in construction. With this configuration, for example, the storage portion of the electronic device 18 can be integrated with the protective cover 28 in particular.

保護カバー３８は、支持手段４２に固定できる複数個の係止体４０として形成する。図３に示すように、支持手段４２は、例えば把手ハウジング６におけるリブ、または窪みとして形成する。この構成により、ケーブルハーネス２６を、特に簡単に、所定位置に正確に組み付けることができる。   The protective cover 38 is formed as a plurality of locking bodies 40 that can be fixed to the support means 42. As shown in FIG. 3, the support means 42 is formed as a rib or a recess in the handle housing 6, for example. With this configuration, the cable harness 26 can be particularly easily and accurately assembled at a predetermined position.

さらに図２、３に示すように、配線１４、もしくは保護カバー３８に、接続線束２４ならびに公衆網接続線３６に、自由な曲折部４４を設ける。この曲折部４４は、組み込まれた状態でも位置的に自由に伸張可能であり、そのため、配線１４の長さ変動を許容し、牽引力が加わっても素線は衝撃を受けない。   Further, as shown in FIGS. 2 and 3, free bend portions 44 are provided in the connection wire bundle 24 and the public network connection wire 36 in the wiring 14 or the protective cover 38. Even when the bent portion 44 is incorporated, the bent portion 44 can be freely extended in position. Therefore, the length of the wiring 14 is allowed to change, and even if a traction force is applied, the strand is not impacted.

このようにして、作動中に振動が発生するとき、把手ハウジング６の主ハウジング１０に対する相対的な運動を、配線１４から素線２８への負担をほとんどかけることなく、相殺することができる。さらに、この構成により、公衆網電源接続線３６を、ハウジング４の外側面に配置できるようになる。これにより、例えば、公衆網電源ケーブル２０を公衆網電源接続線３６に対して離したり、近づけたりするために、公衆網電源接続線３６を掴むことができるようになる。   In this way, when vibration occurs during operation, the relative movement of the handle housing 6 with respect to the main housing 10 can be offset with little burden on the wire 28 from the wiring 14. Furthermore, with this configuration, the public network power connection line 36 can be disposed on the outer surface of the housing 4. Thereby, for example, the public network power supply connection line 36 can be grasped in order to move the public network power supply cable 20 away from or close to the public network power supply connection line 36.

図４ａは、接続線束２４の横断面を示す。図に示すように、複数の素線２８を互いに平行にして保護カバー３８内に埋設する。保護カバー３８は、一方で、穿孔屑および粉塵の付着から素線２８を保護する。さらに、素線２８は、埋設によって相互に固定される。   FIG. 4 a shows a cross section of the connecting wire bundle 24. As shown in the figure, a plurality of strands 28 are embedded in a protective cover 38 in parallel with each other. The protective cover 38, on the other hand, protects the strands 28 from perforations and dust. Furthermore, the strands 28 are fixed to each other by burying.

代案として、図４ｂに示すように、素線２８を保護カバー２８内で互いに離して組み込むことができる。この構成により、素線２８を傷つけうる穿孔屑および粉塵の付着を防ぐために、素線２８を個別に覆うことができ、とくに、素線２８同士の擦れ合いを防ぐこととなる。   As an alternative, as shown in FIG. 4 b, the strands 28 can be incorporated separately within the protective cover 28. With this configuration, the strands 28 can be individually covered in order to prevent perforation dust and dust that can damage the strands 28, and in particular, rubbing between the strands 28 can be prevented.
