Definitions

  • the invention relates to a hand-held, motor-driven oscillation device, according to the preamble of claim 1, as it is used in particular as a hand grinder, on the output shaft of which the required tools, such as grinding wheel, cutting disc, saw blades, scraper spatula or the like. can be attached if necessary.
  • Such oscillation devices are known in different embodiments (see, for example, US 2,350,098, US 4,920,702 and DE 94 10 754.8 Ul).
  • a device always consists of an elongated housing in which an electric motor and an oscillation device are arranged in axial succession.
  • an output shaft protrudes from the housing, to which tools can be attached.
  • a corresponding tool is in each case rigidly attached to the output shaft and, when the output shaft is arranged perpendicular to the longitudinal axis of the device, is essentially always aligned parallel to the longitudinal axis of the oscillation, in particular if a grinding wheel or a cutting disc is used.
  • the object of the invention is therefore to provide an oscillation device as mentioned above.
  • Specify genre that enables comfortable, precise and fatigue-free work, even in narrow work areas.
  • the handle housing part to the oscillating head part with the device output shaft is arranged so as to be pivotable in its angular setting.
  • This allows the working angle to be changed, i.e. the tool attached to the output shaft, e.g. the grinding wheel can assume a different angular position with respect to the handle part and thus to the hand of the worker, which enables easier and also unobstructed processing.
  • the oscillation device can be bent in the zone between the motor and the oscillation device, ie between the handle part containing the motor and the oscillation head part, about a transverse pivot axis which is essentially parallel to the working surface and which preferably intersects the longitudinal axis of the device .
  • the oscillating head on which the respective tool, depending on the embodiment, is more or less closely attached via the oscillating device output shaft protruding therefrom, can be pivoted or adjusted in angle to the rest of the grip part in its angular position about a transverse axis.
  • the complex tool oscillation device takes up a much smaller space during work and can also be used in narrow spaces and relatively inaccessible places. Because the working angle, ie the angle between the grinding surface and the grip part of the device, can now be optimally adjusted, it is possible to work more comfortably, more precisely and thus less tired.
  • an element that transmits the rotational movement at an angle e.g. a universal joint is provided.
  • the shaft extending from the universal joint is a telescopic shaft, so that the rotating drive movement from the electric motor, unaffected by the corresponding angle setting of the oscillating head part, can be transmitted to the oscillating device provided in the head part practically unchanged.
  • the two parts in the pivot axis zone are interrupted and possibly spaced apart, the two parts being connected to one another via at least one pair of pivot arms.
  • These pairs of swivel arms can be lateral ears of the respective housing parts, that is to say they can be made in one piece with them, in which case there is only a partial interruption.
  • the respective housing parts can also have a smooth end closure, from each of which one into the housing protrudes wall material embedded, or firmly connected with this swivel arm. This ensures robust and trouble-free pivotability.
  • the adjustment can be carried out very quickly and easily.
  • the two housing parts namely the oscillating head part and the housing of the handle part are spaced apart from one another on the end face and a flexible housing part, e.g. a bellows is arranged.
  • a flexible housing part e.g. a bellows is arranged.
  • a separate handle part is provided which is pivotably attached to the drive housing containing the drive motor and the oscillation device.
  • the power supply can take place via the handle and on this appropriate switch may be provided.
  • the drive housing and the handle part are practically two separate parts which are only pivotally connected to one another via a joint, there is the possibility of making the drive housing smaller and more compact.
  • the motor, oscillator device and output shaft are arranged in axial succession and alignment in this drive housing and in such a way that the common axis is perpendicular to the machining surface, particularly in the case of grinding with the end face of a grinding wheel.
  • the grip part can be connected to the drive housing in two advantageous arrangements.
  • the swivel bearing is always, e.g. consisting of a bracket attached to the drive housing or integrally formed on this and a handle part bearing fork, or vice versa, designed so that a pivotability by at least 90 °, so seen in the working position, for. B. from a position parallel to the work surface of the handle part to a position perpendicular to this is possible.
  • the handle part swivel attachment can be provided on the drive housing jacket, that is to say in a radial orientation.
  • it can also be provided on the upper housing end face axially opposite the device output shaft, that is to say in the axial alignment.
  • the handle part does not simply extend straight in its longitudinal direction. is designed, but has a gradation.
  • This gradation or offset is to be carried out in such a way that, depending on the radial or axial orientation, this gradation practically overlaps the drive housing.
  • the gradation is drawn upward, so that on the one hand there is greater freedom of finger in relation to the machining surface and on the other hand the handle is pulled closer to the drive housing axis in the vertical position, ie 90 ° swivel position, so that it grips well in this position of the vertical handle with the fist and thus safe guiding with even working pressure is possible.
  • the step of the grip part is introduced downwards, so that deeper gripping is possible with a horizontal orientation of the grip part, which enables, for example, a tilt-free, quieter guidance.
  • the vertical arrangement of the entire drive housing over e.g. a grinding wheel the entire weight of the device can rest on the grinding wheel, so that no additional grinding pressure has to be exerted, and even during the work a large part of the device weight does not have to be constantly supported by hand. So an easy and fatigue-free handling is possible.
  • FIG. 4 a top view of the embodiment according to FIG. 3, with radial handle part articulation
  • FIG. 5 a view of an embodiment similar to that in FIG. 3, but with an axial handle part articulation
  • FIG. 6 a view of an exemplary embodiment similar to that in FIG. 5, but with a stepped grip part.
  • the oscillation device according to the invention in the first embodiment consists of essentially the same basic components as known devices.
  • a device housing 1 which comprises an oscillating head part 3 which comprises an (not shown) electric drive motor and which can also be gripped for holding and handling, and an oscillating head part 3 (also not shown) an oscillating device.
  • These two housing parts 2 and 3 are essentially in axially successive gender longitudinal extension arranged, with an output shaft (not shown here) protruding from the side of the oscillating head part 3 (see, however, FIG. 3), on which, for. B. a grinding wheel 4 is fixedly attached via a fastening device with actuating lever 5.
  • a power cable 7 and a switch 6 are provided on the handle part, on the one hand the power supply and on the other hand the switching on and off of the device are realized.
  • a pivoting device is provided between the handle part 2 and the oscillating head part 3, which cannot be seen in FIG. 1, since it is covered by a bellows 8.
  • a locking head 9 is provided, via which, for example, the position locking for pivoting can be released. From Fig. 2 it can be seen how this pivoting device 10 can be constructed.
  • the two housing parts 2, 3 are arranged such that they can be pivoted relative to one another via two lateral pairs of swivel arms 11 about a common swivel axis 12 which is transverse to the longitudinal axis of the device.
  • a universal joint 13 is provided which connects the output shaft 14 from the drive motor to a drive shaft 15 from the oscillation device.
  • the drive shaft 15 is also designed as a telescopic axis, so that length deviations caused by the pivoting are precisely intercepted by the shaft 15.
  • both the drive motor and the oscillation device are introduced into a single drive housing 17 in such a way that this drive housing 17 comes to a stand in a practically vertical / vertical arrangement with respect to the tool, that is to say the grinding wheel 4.
  • the drive housing 17 with the oscillating output shaft 18 extending therefrom and the grinding wheel 4 are arranged in axial succession, so that during the grinding processing the drive housing 17 comes to stand vertically above the grinding wheel 4.
  • a handle part 19 is pivotally attached to the housing 17 by means of a pivoting device 20, wherein it can be seen in particular from FIG. 4 that this pivoting device 20 consists of a bearing block 21 attached to the drive housing 17 and a handle part bearing fork 22.
  • the bearing swivel device 20 is provided in the embodiment shown in FIGS. 3 and 4 in a radial arrangement with respect to the housing 17. It can be seen that the handle part 19 can be brought from the horizontal, that is parallel to the grinding wheel 4 parallel alignment without problems at least into a vertical position, which is obviously significantly space-saving.
  • the pivoting device 20 is arranged above the upper end face of the housing 17, the bearing block 21 being fastened to the end face of the drive housing or being formed in one piece with it. It can be seen that a pivoting movement, that is to say a change in position of the grip part 19 by at least 180 °, is possible and that in the 90 ° arrangement the grip part 19 is aligned with the drive housing 17 and grinding Disc comes to rest.
  • the handle member 19 may have a cranked or stepped configuration.
  • the step 23 of the grip part 19 is guided around the outer, upper corner 24 of the housing 17 in such a way that a correspondingly lowered grip length 25 of the grip part 19 is available in the horizontal orientation.
