Definitions

  • the invention relates to a power tool with a motor for driving a tool and with at least one switching element.
  • switches are required to turn the motor on and off, and possibly other control functions. It is customary here to use sufficiently robust switches which are designed for the rated operating voltage and are able to switch the sometimes quite high load currents in the range of up to more than 10 amperes. It understands These switches need to be designed to be robust enough not to fail in the professional sector with long operating times and numerous circuits.
  • angle grinders which are designed as so-called "two-hand angle grinder", customary to form the rear end of the housing as a handle to which an on / off switch is provided, which is operated by a button.
  • the angle grinder is then held with one hand during operation on a stem handle received on the side of the housing and with the other hand on the rear handle with the handle button being actuated. If the back handle is released, the power to the motor is interrupted and possibly initiated a braking of the angle grinder.
  • switches could be provided at as many arbitrary positions as possible within the power tool and could be operated in the simplest possible and energy-saving manner.
  • Such flexibility does not exist in conventional power tools, however, because the switches have a considerable size because of the sufficient dimensions and can be integrated only at certain locations in the housing.
  • safety regulations are also to be observed, which is why, for example, an implementation of the supply line to a power switch by a motor housing is possible only with special protective measures that make such an arrangement considerably more expensive or even impossible.
  • switching elements are provided for controlling the motor, which are located in a signal circuit and are coupled via a power switching element with a load circuit.
  • a power tool with a motor which is equipped with a control element for driving the drive switching element, and which has a securing member, which cooperates with the switching member to ensure a two-handed operation on each of the two handles, an actuation of the switching member can only be done when embracing both handles.
  • at least one of the two securing members is designed as an electrically effective line-shaped sensor which controls the drive via a control logic designed as a low voltage.
  • the invention has for its object to provide a power tool having a further improved ergonomics.
  • the operation of the power tool when gripped with one hand to be simplified.
  • This invention is achieved in a power tool with a motor for driving a tool and at least one switching element which is located in a signal circuit and is coupled via at least one power switching element to a load circuit, that at least two Switching elements are provided which can be actuated via elastic touch surfaces, which are integrated in a housing, and that the touch surfaces are arranged in a handle portion of the housing, that the at least two switching elements are operable when grasping with one hand.
  • the special arrangement of the elastic touch surfaces in the gripping region of a housing enables a plurality of switching elements to be actuated when gripped by one hand in order to be able to actuate certain switching elements when gripping the power tool with one hand,
  • the switching elements are operated only in a signal circuit and thus have only reporting function, resulting from the reduced size significantly greater flexibility in the integration into the housing or in a handle. Since the switching elements only have a signaling function and thus are not subjected to the mains voltage, they can also be operated with low voltage, possibly galvanically decoupled from the load circuit. As already mentioned above, the protective measures for producing the necessary contact security of the power tool are thereby significantly simplified.
  • a plurality of switching elements each lying in signal circuits and are coupled to a load circuit via at least one power switching element, are actuated by elastic touch surfaces, which are integrated into the housing of the power tool.
  • the power switching element ensures electrical isolation of the load circuit from the signal circuit or the signal circuits.
  • the power switching element may, for example, be designed as a relay or as a power semiconductor.
  • a relay or as a power semiconductor.
  • an opto-coupler with power semiconductor components is advantageous.
  • the switching elements used preferably have the smallest possible size and are advantageously designed as a microswitch.
  • a microswitch is understood to mean a switching element whose contact opening width between the different switching states is ⁇ 3 mm.
  • Such a design as a microswitch opens due to the small size of the use of multiple switching elements at different points of the power tool to ensure a particularly ergonomic handling.
  • two, three or even more switching elements may be provided at different locations in the grip area of the power tool, which can be actuated from the outside via elastic touch surfaces when the power tool is gripped.
  • about one or more of the switching elements may be formed in an advantageous embodiment of the invention as a button.
  • a power tool can be realized, which requires a permanent operation, for example by grasping a handle and immediately releases the power supply on release or possibly initiates braking.
  • Such an embodiment is particularly advantageous in power tools with a relatively high hazard potential, such as angle grinders, portable circular saws or the like.
  • a plurality of switching elements may be coupled to a circuit via which the motor is switched on when at least two switching elements are closed.
  • the reliability is increased because it can be achieved that the motor is switched on only when a handle or a housing is taken at a specific point that allows the operation of the various switching elements. Furthermore, it can be provided that switching on the power tool is only possible when the power tool is gripped with two hands at different locations.
  • the power tool has at least one actuating or attachment, which is associated with a switching element for state or position control.
  • actuating or attachment numerous control options for an actuating or attachment are possible. For example, it can be ensured that a switching on of the motor is only possible if an actuating element, for example a clamping lever, is in a predetermined position. Furthermore, it can be ensured that, for example, starting of the motor is only possible if a specific attachment is in a predetermined installation position of the power tool.

  • the power tool has a clamping lever for clamping the tool, which is movable between a clamping position and a release position, wherein the clamping lever is associated with a switching element for controlling the clamping position of the clamping lever.
  • Such an embodiment is particularly advantageous in angle grinders having a clamping lever for tool-free voltage of the tool. So it can be ensured with simple means that the angle grinder can only be put into operation when the clamping lever is in the clamping position and thus the tool is securely clamped.
  • a molded body held on the housing of the power tool is provided on which at least one receptacle is provided for fastening a switching element. It may be about a three-dimensionally shaped plastic part.
  • the assembly can be simplified in particular when a plurality of switching elements to be integrated into the power tool.
  • one or more electrical lines can be accommodated on the molded body, which can be connected to the switching element or the switching elements.
  • suitable receptacles for fastening one or more switching elements can be provided on the molded body.
  • the molded body can cooperate with the housing for shielding at least one switching element or electrical lines accommodated on the molded body from contamination by dust, moisture or the like.
