Definitions

  • the invention relates to a side handle for a hand-held tool device, such as a drill or chisel device having a handle member on which an operator can take the side handle or the tool device in a comfortable manner.
  • the side handle has a fastening device for releasable or permanent attachment to the hand tool.
  • the grip element and the fastening device are connected via a decoupling device for partially decoupling vibration of the grip element of the fastening device.
  • the gripping element is guided fixed in position relative to the fastening device by the decoupling device, that is to say that the gripping element has a constant orientation in the case of a relative movement with respect to the fastening device.
  • Such a side handle has the advantage that the decoupling takes place in a certain direction, while a relatively stable guidance is ensured relative to the other directions. As a result, despite a greatly reduced vibration on the gripping element, the operator is given a secure feeling during the guidance of the tool device during operation.
  • DE 101 30 548 describes an auxiliary handle for a hand tool machine in which the grip element is guided translationally parallel to a machining direction of the tool device via a bearing unit.
  • the gripping element is connected to a carriage, which is held displaceably in a rail guide against a spring device.
  • the present invention has for its object to avoid the disadvantages mentioned in a side handle and to ensure comfortable handling with low production costs.
  • the object is achieved in that the decoupling device has two spaced oscillating elements, via which the gripping element is respectively connected to the fastening device and which are deflectable parallel to each other.
  • the grip element can be decoupled from the fastening device in a particularly simple constructive manner, wherein the parallel deflectable oscillation elements of the decoupling device simultaneously ensure a positionally fixed guidance of the grip element.
  • the gripping element during a positively guided by the oscillating elements relative movement relative to the fastening device or relative to the power tool on a constant orientation. In this way, a stable guidance of the tool device is made possible with greatly reduced vibration transmission to the grip element.
  • such a decoupling device can be formed very compact, so that it can be easily integrated into the side handle and there are no obstructions during operation, for example by tilting the decoupling device. Overall, a comfortable handling during operation is thus possible with low manufacturing costs of the side handle.
  • the fastening device has a clamping band which defines a receiving axis for the tool device, wherein the oscillating elements are each deflectable perpendicular to the receiving axis.
  • a decoupling can be achieved for a variety of machine tools, such as in particular drilling and chiseling devices, which is particularly accurate in the direction of the main axis of vibration of the power tool. In this way, a particularly good reduction of the vibrations on the grip element can be achieved.
  • the decoupling device can be fixed via fixing means relative to the receiving axis.
  • a direction in which the decoupling device largely decouples the gripping element from the fastening device can be precisely defined by the fixing means and can also be reliably maintained over the duration of the operation.
  • the oscillating elements are formed by opposing walls of a four-sided spring element.
  • both oscillating elements are formed by a single geneinsames spring element, whereby a particularly accurate parallel kinematics when deflecting the vibrating elements can be achieved.
  • the decoupling device is particularly simple and inexpensive to produce in this way.
  • the spring element is formed from a bent leaf spring, which allows a particularly favorable production of the spring element.
  • the leaf spring is formed of spring steel, whereby a particularly stable decoupling device is provided which has approximately constant deformation properties over its lifetime and thus ensures a permanently comfortable vibration reduction on the grip element.
  • the spring element has two ends which form an overlap region between the oscillating elements. Due to the formation of the overlap region, the production of the decoupling device can be effected in a particularly simple manner by merely bending the spring element. The final definition of the two ends of the spring element to each other can be done by fastening the overlap region on the fastening device or on the handle element.
  • Fig. 1 shows a side handle 2, which is attached to an indicated hand-held tool device 4, in the form of a drill or chisel device.
  • the side handle 2 can also be used on an electric lifting saw or a grinder.
  • the side handle 2 essentially has a fastening device 6, which is connected via a decoupling device 8 with a handle element 10.
  • the fastening device 6 has a clamping band 12 which defines a receiving axis A along the central axis of the free passage opening 13 spanned by it a device neck 14 of the tool device 4 in the clamping band 12 is inserted.
  • the clamping band 12 is now clamped for releasably attaching the side handle 2 to the neck of the device 14 via a tensioning device, not shown.
  • the receiving axis A of the fastening device coincides with a working axis of the tool device, along which the tool device performs a striking, lifting or rotational movement.
  • the decoupling device 8 has a spring element 16, which can be seen in particular from FIG. 2, consists of a leaf spring 18 which is bent so that it forms a four-sided, circumferential profile with an overlap region 20 of the two ends 22.
  • the leaf spring 18 is formed of spring steel.
  • the leaf spring 18 can also be made of a resilient plastic.
  • the overlapping area 20 and the opposite end wall 24 of the spring element 16 each have a mounting hole 26a, 26b. Furthermore, a fixing bore 28 is additionally embedded in the end wall 24.
  • the leaf spring 18 has two mutually parallel and opposing walls 30, which are connected via rounded corner regions 31 with the end wall 24 and the overlap region 20.
  • the walls 30 thus act as parallel to each other deflectable vibrating elements.
  • the spring element 16 is screwed by means of a nut 32 to a threaded rod 34 of the fastening device 6, wherein the threaded rod 34, the mounting hole 26 b in the end wall 24 extends through.
  • the threaded rod 34 the threaded rod 34, the mounting hole 26 b in the end wall 24 extends through.
  • the fixing pin 36 and the fixing hole 28 thus act as fixing means, via which the spring element 16 is aligned relative to the fastening device 6, that the walls 30 are aligned exactly perpendicular to the receiving axis A.
  • the walls 30 are arranged in this position in the direction of the receiving axis A exactly behind one another.
  • the handle member 10 is connected via a fastening means 38 with the spring element 16, wherein the fastening means 38 protrudes through the mounting hole 26 a of the overlap region 20 and thus simultaneously defines the two ends 22 to each other.
  • the handle member 10 in operation, be moved relative to the fastening device 6 and the tool device 4.
  • the handle member 10 is forcibly guided by the two acting as vibrating elements walls 30 of the spring element 16, wherein the walls 30 are always aligned parallel to each other during the swinging movement.
  • the handle member 10 is permanently perpendicular to the receiving axis A and is moved to this substantially parallel.
  • the grip element 10 is decoupled as far as possible from vibrations occurring during operation of the tool device 4 in the direction of the receiving axis A, while in the other directions a stable guidance on the grip element 10 is maintained.
