Abstract
Description
Die Erfindung bezieht sich auf ein Eintreibgerät mit Befestigungsmittel gemäß Oberbegriff
von Anspruch 1 und 8.The invention relates to a driving tool with fasteners according to the preamble
of
Bei einem Eintreibgerät für Schrauben gemäß DE-19 23 712 A1 sind die Zentrierelemente der Zentriervorrichtung für die Schrauben als Haltebacken ausgebildet, die schwenkbar an einem Lagerkörper angeordnet sind und zum Halten der Schrauben Anlageflächen aufweisen, die senkrecht oder geneigt zur Schwenkebene verlaufen. Solche Zentriervorrichtungen sind auch bei Eintreibgeräten für Nägel, Stifte usw. bekannt, die im Folgenden allgemein als "Befestigungsmittel" bezeichnet werden. In a driving tool for screws according to DE-19 23 712 A1 are the centering elements the centering device for the screws designed as holding jaws are pivotally arranged on a bearing body and for holding the screws Have contact surfaces that are perpendicular or inclined to the swivel plane. Such centering devices are also used for driving tools for nails, pens, etc. known, which are generally referred to below as "fasteners".
Aus der US-3 973 605 ist ein Eintreibgerät für Schrauben bekannt, dessen drei Zentrierelemente schwenkbar gelagert sind und jeweils eine senkrecht zur Schwenkebene verlaufende Anlagefläche für die Schraube sowie eine Anlaufschräge für den Kopf der Schraube aufweisen. Die drei Zentrierelemente werden durch einen O-Ring zur Schraube hin zugestellt.From US-3 973 605 a driving tool for screws is known, the three Centering elements are pivotally mounted and one perpendicular to each Contact surface for the screw and a run-on slope for the head of the screw. The three centering elements are fed towards the screw by an O-ring.
Eintreibgeräte mit einem Zentrierelement, das die Schraube U-förmig von drei Seiten umschließt und radial schwenkbar ist, sind aus der US 3 178 971 und der DE 40 37 547 C1 bekannt. Driving tools with a centering element that makes the screw U-shaped encloses on three sides and is radially pivotable, are from the US 3 178 971 and DE 40 37 547 C1 known.
Bei den bekannten Ausführungsformen der Zentriervorrichtung können die Zentrierelemente nachgeben, wenn auf das Befestigungsmittel eine seitliche Kraft einwirkt. Dies bedeutet, daß das Befestigungsmittel beim Einschrauben oder Einschlagen nicht sicher festgehalten wird und unter Umständen schräg in das Werkstück eindringt. Dies ist beim Zusammenbau von Möbeln besonders nachteilig.In the known embodiments of the centering device, the centering elements can yield if a lateral force acts on the fastener. This means that the fastener when screwing in or driving in is not securely held and possibly at an angle into the workpiece penetrates. This is particularly disadvantageous when assembling furniture.
Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Eintreibgeräts der eingangs genannten Art mit einer Zentriervorrichtung für die Befestigungsmittel, die diese beim Eintreibvorgang sicher festhält und führt.The object of the present invention is therefore to create a driving tool type mentioned with a centering device for the fasteners holds and guides them securely during the driving process.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des unabhängigen
Patentanspruches 1 bzw. 8 gelöst.This object is achieved by the features of the
Bei dieser Anordnung der Anlageflächen für das Befestigungsmittel werden alle Seitenkräfte, die unter Umständen auf dieses einwirken, jeweils senkrecht zur Anlagefläche des Zentrierelements und daher von dessen Lager vollständig aufgenommen. Eine Ausweichbewegung des Zentrierelements beim Eintreibvorgang ist nicht möglich und der Schaft des Befestigungsmittels wird somit sicher geführt. With this arrangement of the contact surfaces for the fastener, everyone Lateral forces that may act on it, perpendicular to each Contact surface of the centering element and therefore of its bearing completely added. An evasive movement of the centering element during the driving process is not possible and the shaft of the fastener is thus safely guided.
Damit ist gewährleistet, daß das Befestigungsmittel immer einwandfrei in der gewünschten Richtung in das Werkstück eingetrieben wird. Die Zentrierelemente bewegen sich erst, wenn z.B. bei der Schraube der gegenüber dem Schaft größere Kopf diese auseinanderdrückt oder wenn bei einem Eintreibgerät für Nägel der Eintreibstößel die Zentrierlemente verschwenkt.This ensures that the fastener is always properly in the desired direction is driven into the workpiece. The centering elements only move when e.g. for the screw the larger one compared to the shank Head pushes them apart or when using a nail driver Driving plunger pivoted the centering.
Die Erfindung lässt sich besonders vorteilhaft bei Schraubgeräten verwenden, bei denen das Motorgehäuse mit der motorgetriebenen Einschraubklinge gegen Wirkung einer Feder verschiebbar gegen einen Lagerkörper für die Zentrierelemente angeordnet ist. Dieser Lagerkörper kann dabei auch als Aufsetzfuß ausgebildet sein.The invention can be used particularly advantageously in screwing devices which the motor housing with the motor-driven screw-in blade against Effect of a spring slidable against a bearing body for the Centering is arranged. This bearing body can also be used as Be placed foot.
Bei einer vorteilhaften Weiterbildung der Erfindung sind die Anlageflächen der Zentrierelemente mit die Anlageflächen überragenden, im Wesentlichen quer zur Eintreibrichtung verlaufenden Rippen versehen, die beim Einschrauben in das Gewinde der Schraube eingreifen. In diesem Fall zieht die Schraube den Lagerkörper gegen die Feder zwischen Lagerkörper und Motorgehäuse, so daß für den Bedienungsmann die Kraft zum Zusammenpressen der Feder entfällt.In an advantageous development of the invention, the contact surfaces are Centering elements with the contact surfaces projecting, essentially transverse to Provide driving ribs running when screwing into the Engage the thread of the screw. In this case, the screw pulls the Bearing body against the spring between the bearing body and the motor housing, so that for the operator has no power to compress the spring.
Beim Anschrauben von Gipskartonplatten auf Holz oder Stahl erfolgt die zwangsläufige Vorschubbewegung der Schraube erst nach Erreichen des Werkstücks aus Holz oder Stahl. Sind die Schrauben in bekannter Weise durch einen Verbindungsgurt aus Kunststoff miteinander verbunden, so erreicht der Schraubenkopf den Verbindungsgurt, bevor die Schraube in das Werkstück aus Holz oder Stahl eingreift. Die erzwungene Vorschubbewegung durch die überstehenden Rippen bewirkt nun, daß die Schraube ohne Aufwendung einer zusätzlichen Kraft aus dem Verbindungsgurt herausgedrückt wird.When screwing plasterboard onto wood or steel, this is done inevitable feed movement of the screw only after reaching the Workpiece made of wood or steel. Are the screws through in a known manner a connecting strap made of plastic connected together, so the Screw head the connecting strap before the screw in the workpiece Engages wood or steel. The forced feed movement by the protruding ribs now causes the screw without using a additional force is pushed out of the connecting belt.
Sind die Anlaufschrägen der beiden Zentrierelemente in Eintreibrichtung hintereinander angeordnet, so wird bei ineinander greifenden Anlagebacken das erste Zentrierelement vor dem zweiten Zentrierelement abgehoben, wobei dieses zum Verschwenken freigegeben wird. Are the chamfers of the two centering elements in the driving direction arranged one behind the other, this is the case with interlocking jaws lifted first centering element in front of the second centering element, this is released for pivoting.
Bei der Verwendung der Erfindung bei Druckluftnaglern ist der Lagerkörper fest mit dem Motorgehäuse, also z.B. einer Zylinder-Kolbeneinheit verbunden und lediglich der Einschlagstößel bewegt sich gegen einen Aufsetzfuß.When using the invention in pneumatic nailers, the bearing body is fixed with the motor housing, e.g. connected to a cylinder-piston unit and only the impact ram moves against a foot.
Die Erfindung ist sowohl bei tragbaren wie auch bei stationären Eintreibgeräten anwendbar.The invention applies to both portable and stationary driving tools applicable.
