Description

1 2297514 Hammer drill and/or percussion banner havincr a detachable 5
vibration- damped handle, and a vibration-damoed handle arrancement for a hammer drill and/or Percussion hammer.
Prior art
The invention starts from a hammer drill and/or percussion hammer according to the pre- characterizing clause of Claim 1 and f rom a handle arrangement for a hammer drill and/or percussion hammer according to the pre -characterizing clause of Claim 7. A bammer drill and/ or percussion hammer having a vibration- damped handle is already known (DE 31 21 882 C2), which has damping elements for impact damping at a transition between the handle and a machine casing. The configuration of the damping elements requires a special design of the machine casing and the handle, which is out of the question except for new models. The retrofitting of already existing hammer drills and/or percussion hammers, which are not equipped with a vibration-damped handle, with a vibration damping device of this kind is not possible. Moreover, the vibration damping device of the hammer drill and/or percussion hammer cannot be put out of action.
is Advantages of the invention The hand-held power tool according to the invention, which has the characterizing features of Claim 1, and the handle arrangement according to the invention for a haxamer drill and/or percussion hammer which has the characterizing features of Claim 7, have in contrast thereto the advantage that the novel type of vibration damping can not only be used in new appliances but can also be retrofitted in already existing hawmer drills
R. 27642 and/or percussion hammers, which have no vibration damping, with a corresponding vibration -damped handle. For pure drilling operation with a hammer drill the substitution of the vibration-damped handle by an undamped handle can definitely be advantageous in the improvement of accuracy of guidance.

Claims (9)

Through the measures specified in the subclaims advantageous developments and improvements of the hammer drill and/or percussion hammer indicated in Claim 1 and of the handle arrangement for a hammer drill and/or percussion haymmer indicated in Claim 7 are possible. Drawing Two exemplary embodiments of the invention are illustrated in the drawing and explained in greater detail in the following description. Figure 1 shows a harmer drill and/or percussion hammer with the vibrationdamped handle arrangement detached, Figure 2 shows a handle arrangement with the vibration damping device according to a second exemplary embodiment, and Figure 3 shows a handle arrangement without vibration damping. Description of the exemplary embodiments In Figure 1 a hammer drill, which is provided with a machine casing 11, is designated 10. A drive spindle 12 projects from the machine casing 11 and at its end a tool holder 13 is fastened on it. Inside the machine casing 11 is accommodated a schematically indicated drive motor 14, which is supplied with driving energy via a supply lead 1S. In addition, a percussion mechanism 16 is situated inside the machine casing 11 and is able to deliver blows to a tool (not shown in Figure 1) inserted into the tool holder 13. In the case of the example the hammer drill can be operated alternatively purely as a percussion hazmner, as a percussion hammer combined with a superimposed rotational driving movement of the tool, or purely as a drill without a percussion movement. The invention can of course also be applied to a pure percussion hamner. 1. R. 27642 A handle arrangement 20 can be attached to the machine casing 11 on its side 25 rem te from the tool holder 13. The handle arrangement 20 comprises a handle 21, which is approximately U-shaped and is connected by legs 22, 23 to an approximately plate-shaped mounting element 24. The mounting element 24 is shaped to fit the rear side 25 of the bammer drill 10. In addition, screw connection points 26 are provided on the machine casing 11, and serve to screw the mounting element 24 fast to the machine casing 11 by means of fastening screws 27. On the mounting element 24 a sliding switch 28, by means of which the drive motor 14 of the hammer drill 10 can be switched on and off, is arranged, on the side facing the handle 21, between the legs 22 and 23. is In Figure I the handle arrangement 20 is shown separately from the machine casing 11. The attachment of the handle arrangement 20 to the rear side 25 of the machine casing 11 and the corresponding screwing of the fastening screws 27 into the screw connection points 26 enable the handle arrangement 20 to be joined fast to the machine casing 11. The handle arrangement 20 is provided with a vibration damping device 30. in the exemplary embodiment shown in Figure 1 the vibration damping device 30 comprises a damping spring 32, which is arranged in the region of an upper leg 22, and a pivot joint 31 arranged in the region of a bottom leg 23. In this arrangement the top leg 22 is not joined fixedly to the mounting element 24 but is resiliently coupled by means of the damping spring 32. The handle 21 can pivot resiliently, in accordance with its degree of freedom, about the pivot joint 31 relative to the mounting element 24, as indicated in dashed lines in Figure 1. In this way oscillations and vibrations occurring during the percussion operation of the harmer drill 10 are transmitted with damping to the handle 21, so that the operator of the hammer drill 10 is perceptibly relieved. Figure 2 shows a second exemplary embodiment of a handle arrangement, which is given the reference R. 27642 numeral 220. Said handle arrangement likewise has an approximately U-shaped handle 221, which by means of legs 222 and 223 in joined to a mounting element 224 of similar design to the first exemplary embodiment. in the region of the legs 222 and 223 a vibration damping device 230 is provided. Said device is formed by a modified, vibration- damped nature of the material of the handle 221 in the region of its legs 222, 223. In the case of the example the legs 222, 223 are made of a material which is softer than that of the handle 221 and of the mounting element 224. Thus, the legs 222, 223 are for example made of a soft thermoplastic elastomeric synthetic material having a Shore hardness of approximately 40, while the handle 221 and the mounting element 224 are made of a thermoplastic elastomeric synthetic material which is harder in comparison, having a Shore hardness of approximately 100. The two legs 222 and 223 forming the vibration damping device 230 can be produced, integrally together with the handle 221 and the mounting element 224, in a two-component injection moulding process. The relatively soft legs 222, 223 of the handle 221 have the effect that the handle 221 can be moved resiliently, with damping, relative to the mounting element 224. Figure 3 shows a handle arrangement 320 which has no separate vibration damping device. The handle arrange ment 320 likewise comprises an approximately U-shaped handle 321, which is joined by legs 322, 323 to a mounting element 324. The handle arrangement 320 can be attached, similarly to the other two exemplary embodi ments, to the machine casing 11 of the hammer drill 10, as a substitute. The attachment of the handle arrangement 320 to the machine casing 11 is advantageous particularly when the hammer drill 10 is used for pure drilling, in which case accurate guiding of the tool by means of the handle 321 is necessary. On the other hand, existing hammer drills and/or percussion hanymers, which are provided with the handle arrangement 320, can without difficulty be retrofitted with vibration damping. The present invention is not restricted to the R. 27642 exemplary embodiments illustrated. Thus, instead of the vibration damping device described use may also be made of different advantageous vibration damping. It is essential that this device is arranged on a detachable handle part and, together with the latter, forms a simply substitutable handle arrangement.
