Description

【０００１】
【発明の属する技術分野】
本発明は、手持ち式工作機械であって、機械ケーシングと、機械ケーシングに結合された握りと、握りの背面部を覆い、使用者が押圧面として用いる外殻部材とを備えており、しかも、この外殻部材が、少なくとも２つの取り付け箇所で握り又は機械ケーシングと結合されている形式のものに関する。
【０００２】
【従来の技術】
握りを有し、使用者が押圧面として利用する外殻部材を握りの背面部に備えた手持ち式工作機械は、すでに公知である（ドイツ連邦共和国特許出願公開第１９５３８２５２号明細書）。外殻部材は、その外縁に係合突起を有し、この係合突起は握り内の対応する受容みぞへ係合する。加えて、外殻部材は、握りにねじ固定又は緊締されている。いずれにしても、外殻部材と握りとは、遊びなしに結合されている。外殻部材なしで手持ち式工作機械を作動させることは許されていない。なぜなら、外殻部材によってはじめて、握りが、塵埃や水の侵入から護られるからである。この公知形式の場合、手持ち式工作機械の作動時に生じる振動を、効果的に減衰させることはできない。
【０００３】
さらに、ドイツ連邦共和国特許出願公開第４１２４５７４号明細書により公知のハンマドリルの場合、握りが回り継ぎ手を介して機械ケーシングに取り付けられている。回り継ぎ手に加えて、握りは、ばね装置を介して機械ケーシングと結合されている。この結合形式は、しかし、握りと機械ケーシングとの間のばね行程がばね装置を介してしか制限されていないため、ハンマドリルの取り扱いが難しい。
【０００４】
【発明が解決しようとする課題】
作動時の振動が効果的に減衰され、かつ取り扱い性のよい手持ち式工作機械を提供する。
【０００５】
【課題を解決するための手段】
この課題は、次のようにすることにより解決された。すなわち、握りと外殻部材との間に、押圧方向にほぼ遊びのない結合が保証される第１取り付け箇所を設け、また、握りと外殻部材との間に、押圧方向に、運動のための遊びの余地が残されている第２の取り付け箇所を設けるようにし、さらに、機械ケーシングと外殻部材との間に、少なくとも１つの減衰部材を間挿し、この減衰部材が、予圧を受けて、外殻部材を、握りからはなれる方向で機械ケーシングに設けたストッパの方向へ押し付けるようにしたのである。
【０００６】
【発明の効果】
本発明の利点は、効果的な衝撃緩衝が得られると同時に、手持ち式工作機械の良好な取り扱い性が保証され、しかも、外殻部材を取り外しても、手持ち式工作機械が妨げなしに機能し得る点である。
【０００７】
請求項２以下の各項に記載の措置によって、本発明の手持ち式工作機械の別の有利な構成及び改良が可能である。
【０００８】
【発明の実施の形態】
図１には、手持ち式工作機械１０の後方部分が示されている。手持ち式工作機械１０は、機械ケーシング１１を有し、この機械ケーシングには、とりわけ駆動モータ１２が収納されている。公知形式で２つのケーシング外殻から構成されている機械ケーシング１１には、同じく２つの外殻で構成された握り１３が一体形成されている。握り１３内には、スイッチ１４が配置され、駆動モータ１２は、押しボタン１５を介してスイッチ１４を操作することによって制御可能である。握り１３の自由端１８には、給電ケーブル用の補強スリーブ１９が取り付けられている。握り１３は、公知のピストルの握り様の形状を有し、この形状により、使用者は、工具の送り方向に押圧力を作用させることができる。図示の実施例の場合、手持ち式工作機械１０は、打撃穿孔機械、つまりドリルハンマであり、このドリルハンマでは、ドリルの送りがドリル長手方向に行われるため、押圧力は矢印２１の方向に作用させねばならない。
【０００９】
使用者用の押圧面として役立つのは、主として、握り１３の背面部２４のケーシング壁部である。握り１３のこの背面部２４は、外殻部材２５によって被覆されている。外殻部材２５は硬質の基体２６から成り、基体２６は、押圧面の区域に軟質の上張り２７を有している。
【００１０】
外殻部材２５は、取り付け箇所３０，３１で機械ケーシング１１又は握り１３と結合している。第１取り付け箇所３０は、握り１３の自由端１８の区域に設けられている。握り１３と外殻部材２５との間には、スナップ結合部が設けられている。このスナップ結合部は、基体２６に一体形成された、ばね作用を有する舌状部３２から成っている。外殻部材２５の組み付け位置では、係止鉤３３が、握り１３のケーシングに設けられた突出部３４に係止されるようになっている。
【００１１】
第２取り付け箇所３１は、握り１３の機械側端部の、機械ケーシング１１への延長部の区域に設けられている。取り付けには、押圧方向に対して横方向に外殻部材２５から突出しているラグ３６が役立っている。ラグ３６は、対応して横に延びる、機械ケーシング１１の受容開口３７に係合する。ラグ３６は、その場合、機械ケーシング１１の、ラグのストッパとして役立つオーバーハング３８の内側に当て付けられる。
【００１２】
外殻部材２５のこの特別な取り付け形式によって、第１取り付け箇所３０では、外殻部材２５と握り１３との、押圧方向（矢印２１）でのほぼ遊びのない結合が可能になる。第２取り付け箇所３１では、受容開口３７がラグ３６より明らかに広幅なので、押圧方向（矢印２１）に、移動のための明らかな遊びが存在する。他方、外殻部材２５は、その第１取り付け箇所３０を中心として限界内を旋回可能であり、それにより、ラグ３６は、矢印方向２１への押圧時に、オーバーハング３８に向かい合った、機械ケーシング１１のところのストッパに押し付けられ得る。
【００１３】
手持ち式工作機械１０の打撃作用に基づき、作動中に振動が握り１３へ伝えられる。外殻部材２５と機械ケーシング１１との間には使用者に作用する振動を低減するために、減衰部材４０が間挿されている。外殻部材２５には支持面４１が形成されており、この支持面が減衰部材４０に密着している。減衰部材４０は、対応接触面４２により機械ケーシング１１に対して支えられている。減衰部材４０は、緩衝作用を有する材料製、例えば軟質ゴム製である。
【００１４】
図２には、外殻部材２５が、握り１３から取り外して示されている。握り１３は、外殻部材２５なしでも完全に機能でき、手持ち式工作機械の場合に通常の形式で２つのケーシング外殻から構成されている。これら２つのケーシング外殻は、手持ち式工作機械１０のほぼ長手方向平面で分割されている。手持ち式工作機械１０は、図２に示した形式では、握り１３のところに特別な減衰措置が施されていない従来形式の手持ち式工作機械同様の作動が可能である。握り１３の区域には、後方へ向かって開いた、減衰部材４０用の凹部４３と、外殻部材２５に設けられた補剛リブ４５用の切欠き４４と、第２取り付け箇所３１に設けられた受容開口３７と、第１取り付け箇所３０に設けられた突出部３４とが、外部から見える。
【００１５】
握り１３を効果的に緩衝するために、凹部４３内へは減衰部材４０がはめ込まれる。この目的のためには、機械ケーシング１１の双方のケーシング外殻を分離し、それらの間に減衰部材４０を挿入せねばならない。双方のケーシング外殻が継ぎ合わされた後には、減衰部材４０は、縁部４０ａを介して握り１３及び機械ケーシング１１内に形状係合式に保持されることになる。外殻部材２５を取り付けるには、まずラグ３６を受容開口３７へ挿入し、次いで、第１取り付け箇所３０の側の端部を、握り１３に押し付けることによって、舌状部３２が突出部３４のところで弾性的にたわみ、最後に係止鉤３３が突出部３４の背後に係止され得る。これで、外殻部材２５は、工具なしで手持ち式工作機械１０へ付加取り付けされ、矢印４８の方向へ押圧力を加えられていない状態の、図３に示した休止位置を占める。外からは見えないため、破線で示した機械ケーシング１１の輪郭１１ａ，２５ａと外殻部材２５との間には、第２取り付け箇所３１の区域に、遊びｓが存在している。その場合、機械ケーシング１１と外殻部材２５との間には、減衰部材４０が間挿されており、それにより外殻部材２５が、予圧によって握り１３から離れる方向で機械ケーシング１１に設けたストッパ３８の方向へ押し付けられる。このため、遊びは、最大値ｓに制限される。外殻部材２５は、例えば、２つの外殻から成る機械ケーシング１１を開くことで取り外すことが可能である。なぜなら、その場合には、係止鉤３３が、突出部３４のところを横方向に移動可能だからである。しかし、また握りのケーシングに開口を設けて、舌状部３２が、この開口を介して、突出部３４のところで解離する方向で押し返され得るようにすることも考えられる。
【００１６】
図４には、手持ち式工作機械１０が作業状態で示されている。この場合、外殻部材２５へ使用者により押圧力が加えられている。減衰部材４０は、それによって最大で遊びｓだけ弾性変形される。外殻部材２５は、その場合、少なくともそのラグ３６が機械ケーシング１１に接触する。

BACKGROUND OF THE INVENTION
The present invention is a hand-held machine tool, comprising a machine casing, a grip coupled to the machine casing, an outer shell member that covers the back of the grip and is used as a pressing surface by the user, This outer shell member is of the type in which it is connected to a grip or a machine casing at at least two attachment points.
[0002]
[Prior art]
A hand-held machine tool having a grip and an outer shell member used as a pressing surface by a user on the back surface of the grip is already known (German Patent Application Publication No. 19538252). The outer shell member has an engaging projection on its outer edge that engages a corresponding receiving groove in the handle. In addition, the outer shell member is screwed or tightened to the grip. In any case, the outer shell member and the grip are joined without play. It is not permitted to operate a hand-held machine tool without a shell member. This is because the grip is protected from the invasion of dust and water only by the outer shell member. In the case of this known type, the vibration generated when the hand-held machine tool is operated cannot be effectively damped.
[0003]
Furthermore, in the case of the hammer drill known from DE 41 24 574 A1 a grip is attached to the machine casing via a swivel joint. In addition to the swivel joint, the grip is connected to the mechanical casing via a spring device. However, this type of coupling is difficult to handle the hammer drill because the spring travel between the grip and the machine casing is limited only via a spring device.
[0004]
[Problems to be solved by the invention]
Provided is a hand-held machine tool in which vibration during operation is effectively damped and easy to handle.
[0005]
[Means for Solving the Problems]
This problem has been solved as follows. That is, a first attachment portion is provided between the grip and the outer shell member to guarantee a substantially free play in the pressing direction, and the movement is performed in the pressing direction between the grip and the outer shell member. A second mounting portion is provided that leaves room for play, and at least one damping member is interposed between the machine casing and the outer shell member, and the damping member is subjected to preload. the outer shell member is had to so that the pressing in the direction of the setting digit stopper in the machine casing in the direction to become from grip.
[0006]
【The invention's effect】
The advantage of the present invention is that an effective shock buffering can be obtained, and at the same time, good handling of the hand-held machine tool is guaranteed, and even if the outer shell member is removed, the hand-held machine tool functions without interruption. It is a point to get.
[0007]
By means of the measures described in the following claims, further advantageous configurations and improvements of the hand-held machine tool according to the invention are possible.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a rear portion of a hand-held machine tool 10. The hand-held machine tool 10 has a machine casing 11 in which a drive motor 12 is housed. A grip 13 which is also composed of two outer shells is integrally formed in a mechanical casing 11 which is composed of two casing outer shells in a known manner. A switch 14 is disposed in the grip 13, and the drive motor 12 can be controlled by operating the switch 14 via the push button 15. A reinforcing sleeve 19 for a power supply cable is attached to the free end 18 of the grip 13. The grip 13 has a known pistol grip-like shape, which allows the user to apply a pressing force in the feed direction of the tool. In the case of the illustrated embodiment, the hand-held machine tool 10 is an impact drilling machine, that is, a drill hammer. In this drill hammer, the feed of the drill is performed in the longitudinal direction of the drill, so the pressing force must be applied in the direction of the arrow 21. Don't be.
[0009]
It is mainly the casing wall portion of the back portion 24 of the grip 13 that serves as a pressing surface for the user. The back surface 24 of the grip 13 is covered with an outer shell member 25. The outer shell member 25 is composed of a hard base 26, and the base 26 has a soft upper layer 27 in the area of the pressing surface.
[0010]
The outer shell member 25 is coupled to the mechanical casing 11 or the grip 13 at the attachment points 30 and 31. The first attachment point 30 is provided in the area of the free end 18 of the grip 13. A snap coupling portion is provided between the grip 13 and the outer shell member 25. The snap coupling portion is formed of a tongue-like portion 32 having a spring action and formed integrally with the base body 26. At the assembly position of the outer shell member 25, the locking rod 33 is locked to the protrusion 34 provided on the casing of the grip 13.
[0011]
The second attachment location 31 is provided in the area of the extension to the machine casing 11 at the machine side end of the grip 13. For the attachment, a lug 36 protruding from the outer shell member 25 in a direction transverse to the pressing direction is useful. The lug 36 engages a receiving opening 37 in the machine casing 11 correspondingly extending laterally. The lug 36 is then applied to the inside of the machine casing 11 overhang 38 which serves as a lug stopper.
[0012]
This special attachment form of the outer shell member 25 allows the outer shell member 25 and the grip 13 to be joined with almost no play in the pressing direction (arrow 21) at the first attachment point 30. At the second attachment point 31, the receiving opening 37 is clearly wider than the lug 36, so there is a clear play for movement in the pressing direction (arrow 21). On the other hand, the outer shell member 25 is pivotable within limits around its first attachment point 30 so that the lug 36 faces the overhang 38 when pressed in the arrow direction 21. Can be pressed against the stopper.
[0013]
Based on the striking action of the hand-held machine tool 10, vibration is transmitted to the grip 13 during operation. A damping member 40 is interposed between the outer shell member 25 and the mechanical casing 11 in order to reduce vibrations acting on the user. A support surface 41 is formed on the outer shell member 25, and this support surface is in close contact with the damping member 40. The damping member 40 is supported against the mechanical casing 11 by the corresponding contact surface 42. The damping member 40 is made of a material having a buffering action, for example, soft rubber.
[0014]
In FIG. 2, the outer shell member 25 is shown detached from the grip 13. The grip 13 can function completely without the outer shell member 25 and is composed of two casing shells in the usual manner in the case of hand-held machine tools. These two casing shells are divided in a substantially longitudinal plane of the hand-held machine tool 10. In the form shown in FIG. 2, the hand-held machine tool 10 can operate in the same manner as a conventional hand-held machine tool in which no special damping measure is provided at the grip 13. In the area of the grip 13, a recess 43 for the damping member 40, a notch 44 for a stiffening rib 45 provided on the outer shell member 25, and a second attachment location 31 are provided. The receiving opening 37 and the protrusion 34 provided at the first attachment location 30 are visible from the outside.
[0015]
In order to cushion the grip 13 effectively, a damping member 40 is fitted into the recess 43. For this purpose, both casing shells of the mechanical casing 11 must be separated and the damping member 40 inserted between them. After both casing shells are spliced together, the damping member 40 is held in shape engagement in the grip 13 and the machine casing 11 via the edge 40a. In order to attach the outer shell member 25, first, the lug 36 is inserted into the receiving opening 37, and then the end portion on the side of the first attachment location 30 is pressed against the grip 13, so that the tongue-like portion 32 of the projecting portion 34. By the way, it bends elastically, and finally the locking rod 33 can be locked behind the protrusion 34. The outer shell member 25 is now attached to the hand-held machine tool 10 without a tool and occupies the rest position shown in FIG. 3 in a state where no pressing force is applied in the direction of the arrow 48. Since it cannot be seen from the outside, there is a play s in the area of the second attachment location 31 between the outline 11a, 25a of the mechanical casing 11 indicated by the broken line and the outer shell member 25. In that case, a damping member 40 is inserted between the machine casing 11 and the outer shell member 25, so that the outer shell member 25 is provided with a stopper provided on the machine casing 11 in a direction away from the grip 13 due to preload. It is pressed in the direction of 38. For this reason, the play is limited to the maximum value s. The outer shell member 25 can be removed, for example, by opening the mechanical casing 11 composed of two outer shells. This is because in that case, the locking rod 33 can move in the lateral direction at the protruding portion 34. However, it is also conceivable that an opening is provided in the grip casing so that the tongue 32 can be pushed back in the direction of disengagement at the projection 34 through this opening.
[0016]
FIG. 4 shows the hand-held machine tool 10 in the working state. In this case, a pressing force is applied to the outer shell member 25 by the user. The damping member 40 is thereby elastically deformed by a maximum of play s. In this case, at least the lug 36 of the outer shell member 25 contacts the mechanical casing 11.
