Definitions

  • the invention relates to a handle device for a hand tool according to the preamble of the independent claims.
  • Antivibration handles with an elastic connection to the hammer also cause relative movements between the hammer and the handle itself due to the required rigidity as a side effect. From this, requirements for the interface between a hammer and an anti-vibration handle can be derived:
  • the invention relates to a handle device for a hand tool having an operating mode switching device and a drive device for driving an insert tool in different modes, with at least one spring element and with a machine housing at least limited movably mounted handle unit, which over the at least one spring element relative to the Machine housing is at least partially vibration decoupled and comprises a switch actuator to a commissioning of the drive device, wherein the switch actuator can be switched both mono-stable and bi-stable between two switching positions.
  • the handle device has an intermediate plate, which is provided in the machine housing and which accommodates at least the spring element on one side, and a control means, via which the switch actuator with the Radiogon tenschaltschaltvoriques cooperates such that in certain modes of the switch actuator is not bi-stable can be switched.
  • a control means via which the switch actuator with the Radiogon tenschaltschaltvoriques cooperates such that in certain modes of the switch actuator is not bi-stable can be switched.
  • the switch actuator only has a stable switching position, in which the switch actuator can be switched or in which the switch actuator preferably falls back automatically, while the switch operator in at least one other switching position of a operator must be kept in particular.
  • the term "bi-stable” should be understood in particular to mean that the switch actuator has two stable switching positions into which the switch actuator can be switched
  • Switch actuator is preferably formed as an on-off switch of the power tool.
  • the handle device according to the invention solves the task in a simple to assemble and cost-effective manner. It fulfills all requirements placed on it.
  • control means is designed as a drawstring.
  • the drawstring may preferably be made of a plastic or other material that appears appropriate to a person skilled in the art.
  • the tension band preferably has an at least substantially rectangular cross section with an at least substantially circular-like, in particular circular middle fiber. It is also conceivable for the middle formers to have an at least essentially four- or hexagonal or another cross-section which appears expedient to a person skilled in the art.
  • the middle fiber is preferably provided to serve at least partially as a filling channel, in particular during an injection process, and / or to form an advantageously narrow contact line with the leaf spring.
  • the drawstring may preferably be made of a plastic. As a result, an advantageous cost-effective design can be achieved.
  • the at least one spring element is formed by a leaf spring.
  • the handle device has at least one secondary spring element, which is formed by an elastomeric spring element.
  • the spring element formed by the leaf spring can be advantageously supported in a spring action, and use of the handle device, in particular in larger and more powerful hand tool machines, can be achieved.
  • the secondary spring element is acted upon only after a certain compression travel. It is proposed that the spring stiffness of the spring element formed by the leaf spring is adjusted so that with a compression travel between 2 mm and 10 mm, preferably between 3 mm and 7 mm, more preferably between 4 mm and 5 mm minimum operating pressure points for most important Use cases can be achieved. From this Andruckschwelle the secondary spring element begins to act. The more volume of the
  • Eiastomerfederelements is designed such that at an additional compression of 2 mm to 5 mm, in particular from 3 mm to 4 mm over a minimum operating pressure point beyond the elastomeric spring element is compressed to 70% of its original volume. In a further compression of 1 mm to 2 mm, virtually the entire volume of the Eiastomerfederelements is acted upon, so that the spring stiffness increases relatively quickly. This has the advantage that in a case on the Antivibrati- onshandgriff very much energy can be absorbed, so that the impact-like components are less loaded.
