Definitions

  • the invention relates to a hand-held, preferably beating, power tool with a handle and a preferably continuously adjustable switch with actuating rocker, wherein the actuating rocker is detachably lockable in an operating position, wherein the actuating rocker is mounted longitudinally displaceable against a return spring and latched after the longitudinal displacement in the depressed operating position, which latching by a pressure force releasable again and the actuating rocker is releasable by subsequent automatic longitudinal displacement again.
  • a power tool having the features mentioned, is known from DE 36 38 952 A.
  • the storage as well as the releasable locking of the actuating rocker in the power tool described there using a plurality of individual components to form a power-lock device and a shut-off device is very complex, with the releasable locking of the actuation rocker described therein by the function of the turn-off-blocking device described therein is possible.
  • the invention is therefore based on the object, a striking tool with a lockable actuating rocker for an operating switch in such a way that with a simple structure a simple one-handed operation by the Rocker-operated hand is possible and at the same time accidental re-release of the pressed rocker is prevented.
  • the invention provides that the actuating rocker is mounted at the end of the bearing in slots and is provided with a hook which engages latching after the longitudinal displacement in the depressed operating position from behind into a transverse pin of the handle, wherein the latch is formed so that they can only be released by a relatively large - an accidental release on contact with the actuating rocker preventing - compressive force.
  • the inventive arrangement is required to lock the rocker switch only a longitudinal displacement, which is easily accessible by moving the operating hand or index finger of the actuating hand against the not too large restoring force of the return spring to subsequently when releasing to achieve that a rocker spring, against the Rocker for continuous adjustment of the switch position works, the rocker pressed back again, in which case the hook snaps behind the cross pin.
  • the locked operating position thus does not quite correspond to the maximum possible Eindgurwolf sued the rocker and the resulting maximum displacement position of the switch.
  • the rocker switch can be provided with a profiling, in particular a protruding end projection for pulling the rocker into the locking position ,
  • An essential point of the rocker switch according to the invention is its design such that it can not be unlocked accidentally by touching again, but that this a considerable pressure force must be expended.
  • This can be achieved in a further embodiment of the invention simply in that the hook is provided with a voltage applied to the transverse pin pin pressing the rocker, which is set so that in conjunction with the spring strength of the return spring and the strength of the rocker spring the desired pressure force as desired triggering force.
  • a continuously variable switch 4 which is actuated by a schematically indicated switch pin 5, which is adjustable by means of a bearing shaft 6 on one side mounted rocker switch 7.
  • the bearing shaft 6 of the rocker switch 7 is in slots 9 of the shells 1 a and 1 b, which are not visible in the drawings and which lie above or below the recesses 8 of the switch stored, wherein they by a return spring 10 in the in FIG 1 is pulled down position shown pulled.
  • the web 11, together with a stop in the interior of the rocker switch 7 a Ausschwenkbegrenzung this rocker, by which it is held in the relaxed position shown in Fig. 1. In this position to the outside it is biased by the rocker spring 12.
  • a hook 13 is formed on top, which can be moved when pressed inward of the rocker under a handle transversely traversing cross pin 14.
  • a bevel 16 is formed, which is removed in the locking position according to FIGS. 4 and 5 only by fractions of a millimeter from the transverse pin 14, so practically immediately when pressing the transverse pin 14 at this slope 16 takes place.
  • the rocker To re-trigger the rocker switch from the operating position shown in FIGS. 4 and 5, the rocker must first be moved against the action of the return spring 10 back up so that the cross pin can escape under the hook and the hook over the fixed Cross pin slides away. From the inclination of the slope 16 and the force K R of the return spring 10 results in the release force for unlocking the rocker switch.
  • This release force should be relatively high, so that accidental release is prevented by a touch of the rocker switch. This should only be unlocked by a conscious greater release pressure.
