Die vorliegende Erfindung betrifft ein handgeführtes Eintreibgerät der im Oberbegriff von Patentanspruch 1 genannten Art. Derartige handgeführte Eintreibgeräte verfügen über einen versetzbar geführten Eintreibstössel über den Befestigungselemente in einen Untergrund eintreibbar sind.The present invention relates to a hand-held tacker referred to in the preamble of claim 1. Art Such hand-held tackers have a displaceably guided Eintreibstössel on the fasteners are driven into a ground.
Als Antriebsquelle für den Eintreibstössel dient dabei eine mechanische Antriebsfeder, die über einen Spannmechanismus spannbar ist. Von Vorteil ist dabei, dass die mechanische Antriebsfeder kostengünstig ist, wodurch ein derartiges Eintreibgerät preiswert herzustellen ist.The drive source for the drive ram is a mechanical drive spring, which can be tensioned via a clamping mechanism. The advantage here is that the mechanical drive spring is inexpensive, whereby such a tacker is inexpensive to manufacture.
Aus der
Von Nachteil bei dem bekannten Eintreibgerät ist, dass bei einer ungewollten Beschleunigung des Eintreibgerätes, z. B. wenn dieses von einer erhöhten Position in eine relativ niedrigere Position fällt, die Sperreinrichtung unbeabsichtigt in ihre Freigabestellung überführt werden könnte.A disadvantage of the known tacker is that at an unwanted acceleration of the tacker, z. B. if this falls from an elevated position to a relatively lower position, the locking device could be inadvertently transferred to its release position.
Die Aufgabe der vorliegenden Erfindung liegt daher darin, ein Eintreibgerät der vorgenannten Art zu entwickeln, das die vorgenannten Nachteile vermeidet.The object of the present invention is therefore to develop a tacker of the aforementioned type, which avoids the aforementioned disadvantages.
Diese Aufgabe wird erfindungsgemäss durch die in Anspruch 1 genannten Massnahmen gelöst. Demnach ist an dem Eintreibgerät eine vom Auslöseschalter unabhängige mechanische Blockiereinrichtung für die Sperreinrichtung vorgesehen, die zwischen einer Aktivstellung und einer Passivstellung hin und her schaltbar ist, wobei die Sperreinrichtung in der Aktivstellung der mechanischen Blockiereinrichtung in ihrer Sperrstellung arretiert und in der Passivstellung der mechanischen Blockiereinrichtung in ihre Freigabestellung überführbar ist. Durch diese Massnahme kann sichergestellt werden, dass ein unbeabsichtigtes Betätigen der Sperreinrichtung durch Stösse oder andere Fremdeinwirkung nicht auftreten kann. Es ist dadurch ferner sichergestellt, dass durch eine elektronische Fehlfunktion der Steuerelektronik nicht ungewollt ein Setzvorgang ausgelöst werden kann.This object is achieved according to the invention by the measures mentioned in claim 1. Accordingly, an independent of the trigger switch mechanical blocking device for the locking device is provided on the tacker, which is switchable between an active position and a passive position, the locking device locked in the active position of the mechanical locking device in its blocking position and in the passive position of the mechanical locking device in their release order is transferable. By this measure, it can be ensured that an unintentional actuation of the locking device by impacts or other external influences can not occur. It is thereby further ensured that by an electronic malfunction of the control electronics not accidentally a setting process can be triggered.
Vorteilhaft weist die mechanische Blockiereinrichtung wenigstens ein Blockiermittel auf, das mit einem mechanischen Anpressfühler gekoppelt ist, wobei die Sperreinrichtung ein Gegenelement, das über das Blockiermittel blockierbar ist, aufweist. Auf diese Weise kann über die mechanische Blockiereinrichtung abgefragt werden, ob das Eintreibgerät ordnungsgemäss an ein Werkstück angepresst ist. Es wird also ermittelt, ob der Anwender einen Eintreibvorgang vorbereitet und das Eintreibgerät in Setzbereitschaft ist.Advantageously, the mechanical blocking device has at least one blocking means, which is coupled to a mechanical contact pressure sensor, wherein the blocking device has a counter element which can be blocked by the blocking means. In this way it can be queried via the mechanical blocking device, whether the tacker is properly pressed against a workpiece. It is thus determined whether the user prepares a drive-in process and the tacker is ready to set.
Vorteilhaft weist die mechanische Blockiereinrichtung wenigstens ein Blockiermittel auf, das mit einem mechanischen Detektionsmittel für eine Stromquelle gekoppelt ist, wobei die Sperreinrichtung ein Gegenelement, das über das Blockiermittel blockierbar ist, aufweist. Auf diese Weise kann über die mechanische Blockiereinrichtung abgefragt werden, ob eine Stromquelle, wie z. B. ein Akku oder eine Batterie, in der entsprechenden Aufnahme am Eintreibgerät vorhanden ist. Es kann also kein Eintreibvorgang ausgelöst werden, wenn keine Stromquelle in der Aufnahme anwesend ist.Advantageously, the mechanical blocking device has at least one blocking means which is coupled to a mechanical detection means for a current source, wherein the blocking device has a counter element which can be blocked by the blocking means. In this way can be queried via the mechanical blocking device, whether a power source, such. B. a rechargeable battery or a battery, is present in the appropriate recording on Eintreibgerät. So it can not be triggered driving when no power source is present in the recording.
Von Vorteil ist es ebenfalls, wenn die mechanische Blockiereinrichtung so ausgelegt ist, dass sich in der Aktivstellung der mechanischen Blockiereinrichtung wenigstens immer eines der Blockiermittel in einer das zugeordnete Gegenelement blockierenden Stellung befindet. Um die mechanische Blockiereinrichtung in die Passivstellung zu überführen, so dass die Sperreinrichtung über den Auslöseschalter in die Freigabestellung überführbar ist, müssen also alle Blockiermittel in ihre die Sperreinrichtung bzw. die zu dieser gehörenden Gegenelemente nicht blockierende Stellung verfahren worden sein.It is also advantageous if the mechanical blocking device is designed so that at least one of the blocking means is in the active position of the mechanical blocking device in a position blocking the associated counter-element. In order to transfer the mechanical blocking device in the passive position, so that the locking device on the trigger switch can be transferred to the release position, so all blocking agents must have been moved into their blocking device or the counter-elements belonging to this non-blocking position.
Vorteilhaft ist das wenigstens eine Blockiermittel über ein Federelement in Richtung auf seine das zugeordnete Gegenelement blockierende Stellung beaufschlagt, so dass die mechanische Blockiereinrichtung also immer automatisch wieder in ihre Aktivstellung versetzbar ist, z. B. wenn das Eintreibgerät von einem Werkstück abgehoben wird oder wenn die Stromquelle bzw. der Akku aus der Aufnahme entnommen wird.Advantageously, the at least one blocking means is acted upon by a spring element in the direction of its blocking the associated counter-element position, so that the mechanical blocking device is always automatically put back into its active position, z. B. when the tacker is lifted from a workpiece or when the power source or the battery is removed from the recording.
