Definitions

  • the present invention relates to a hand-held machine tool, in particular a hand-held oscillation machine tool with an outer housing extending essentially along a longitudinal axis and having a grip area which is provided for grasping around and for guiding the machine tool with a user's hand.
  • Hand-held machine tools are known from the prior art, the housings of which are either firmly screwed to the drive devices of the machine tool or have housings which consist of shell components, mostly half-shells, which are firmly connected to one another.
  • the housings of the machine tools known in the prior art are at least partially in contact with elements of the drive device, which means that, simultaneously with a transfer of the executives from the user to the machine tool and the machining forces from the Machine to the user and structure-borne noise, heat and vibrations are transmitted from the drive devices to the housing, whereby the work safety and the ease of use of such a machine tool is impaired.
  • US 2009/0194306 A1 discloses a machine tool having a housing.
  • a motor and an associated drive mechanism are arranged in the housing, which together form a motor / drive mechanism arrangement.
  • At least one resilient body surrounds part of the motor / drive mechanism assembly to resiliently decouple it from the housing.
  • US 2010/0068977 A1 discloses a sander having a two-part housing.
  • a motor of the grinding device is arranged in a lower housing part.
  • An upper housing part has a handle.
  • a damping element is arranged between the overlapping upper and lower housing parts.
  • DE 10 2005 016 453 A1 discloses a handheld power tool with a motor housing and a housing cover which is attached to the motor housing.
  • the hand-held power tool has an insulating means which rests on the motor housing and the housing cover and is guided by a guide means in the direction of the motor housing and / or the housing cover.
  • U.S. 5,394,039 discloses a motor housing with a vibration damper which is arranged in a recess in the housing part. The linear vibration damper is compressed between the motor and the housing part.
  • the invention is therefore based on the object of providing a hand-guided machine tool with improved ease of use.
  • a hand-guided machine tool can in particular also be a hand-guided oscillation machine tool.
  • a hand-guided machine tool has an outer housing that extends essentially along a longitudinal axis and has a grip area which is provided for grasping around and for guiding the machine tool with one hand of a user.
  • An electrical drive unit which rotates a drive shaft of the machine tool, is accommodated essentially within this outer housing.
  • the axis of rotation of the drive shaft is aligned essentially parallel to a longitudinal axis of the outer housing or can also coincide with this.
  • a tool device which is arranged in an end region of the outer housing, is essentially rigidly coupled to the electric drive unit.
  • the tool device can be arranged directly at a first end of the electric drive unit.
  • the tool device can be arranged on another device, such as a fan device, for example, which is preferably likewise essentially rigidly coupled to the electric drive unit.
  • rigidly coupled means that these devices are mechanically coupled, as a result of which movements, also of a high-frequency type, such as vibrations, for example, are transmitted from one element to the other.
  • a rigid connection can therefore also be implemented in the context of the present invention by means of an integral construction or the like.
  • the outer housing of the handheld machine tool according to the invention has a defined inner contour.
  • the electric drive unit and the tool device essentially rigidly coupled to it have a defined outer contour, the tool device having a defined outer contour at least as far as this is arranged in the area of the outer housing.

  • the outer contour of these drive elements and the inner contour of the outer housing are designed in such a way that they are spaced apart from one another by a predetermined minimum distance.
  • first support devices are provided on the outer contour of the electric drive unit and tool device and a number N of second support devices on the inner contour of the outer housing.
  • the first support devices and the second support devices interact in such a way that they keep the outer contour and the inner contour at this minimum distance from one another.
  • the interaction of the first and second support devices keeps the inner contour and thus the outer housing and in particular the grip area of the hand-held machine tool at a distance from the outer contour and thus at a distance from the electric drive unit and the tool device.
  • the transmission of structure-borne noise, heat and vibrations from these drive elements, which are essentially rigidly coupled to one another, to the housing is thereby reduced, which significantly improves the work safety and the ease of use of the machine tool.
  • the first and second support devices enable one Sufficient transfer of support forces such as managers from the user to the machine tool and the machining forces from the tool to the user.
  • the tool device serves to transmit the drive torque of the electric drive unit to a tool which is preferably arranged on the tool device.

  • the machine tool preferably has a tool holder, the drive axis of which can also be arranged pivoted at an angle with respect to the drive axis of the electric drive element.
  • the tool holder can be arranged at an outer end of the drive axis, but it can also be arranged in an area spaced apart from the end of the tool device.
  • the tool holder can also be arranged in a recess in the area of the drive shaft in the tool device, into which a tool can be inserted.

  • the defined outer contour of the electrical drive device and the tool device is preferably obtained essentially from the shape of these drive elements, which is influenced in particular by their drive function and by requirements for an ergonomic machine tool design.
  • the defined inner contour of the outer housing preferably follows the defined outer contour of the electric drive device, at least in some areas and - as far as the outer housing encloses this - the tool device.
  • the outer contour and the inner contour are at a minimum distance from one another. This avoids direct transfer of structure-borne noise, heat and vibrations, which arise in particular from the drive of the tools and as a result of the machining processes, from the outer contour to the inner contour and thus to the outer housing.
  • the predetermined minimum distance is in particular in a range up to 5 mm, preferably between 1 mm and 3 mm and particularly preferably about 2 mm.
  • the predetermined minimum distance and the air layer thus lying between the outer contour and the inner contour leads not only to mechanical decoupling but also to a further reduction in the heat transferred from the drive unit and the tool device to the housing.
  • a number N of first support devices are arranged on the outer contour of the drive elements and a number N of second support devices are arranged on the inner contour of the outer housing.

  • the inner contour is arranged in the grip area of the outer housing at a minimum distance from the outer contour of the drive elements of the machine tool and can preferably move in this area relative to the outer contour in accordance with the elasticity of the outer housing, which also results in a certain mechanical decoupling of the grip area from the drive elements. This also contributes to the improved ease of use of the machine tool.
  • an edge area is arranged at the front end of the outer housing, which is preferably designed in the direction of the tool unit, but at the same time maintains a minimum distance between the outer housing and the outer contour of the tool device.
  • the edge area is designed in such a way that it preferably serves both as a privacy screen and as a safety device which prevents objects from penetrating from the tool device. Such objects could lead to an impairment of the functionality of the machine tool and in particular to a transmission of vibrations, sound or heat from the drive elements to the outer housing.
