Aus der
Der Führungskanal ist entgegen der Setzrichtung von einer setzrichtungsseitigen Stirnseite des Führungselementes begrenzt. Eine entgegen der Setzrichtung weisende Gegenfläche, die Teil eines in dem Auflageelement angeordneten Zwischenstückes ist, bildet eine Begrenzung des Führungskanals in Setzrichtung. Dieses Zwischenstück ist mit Hilfe einer weiteren Schraube in drei unterschiedlichen Stufen entlang des Auflageelementes festlegbar. Die weitere Schraube durchsetzt dabei eine von drei seitlich angeordneten Durchgangsbohrungen des Auflageelementes und ragt in eine weitere Gewindebohrung in dem Auflageelement.The guide channel is limited against the setting direction of a setting direction-side end face of the guide element. A counter surface facing the setting direction, which is part of an intermediate piece arranged in the support element, forms a boundary of the guide channel in the setting direction. This adapter is with Help of another screw in three different stages along the support element can be fixed. The other screw passes through one of three laterally disposed through holes of the support element and protrudes into a further threaded hole in the support element.
Neben der kreisrunden Ausnehmung für das Stellelement und den Durchgangsbohrungen für die mit dem Zwischenstück zusammenwirkende weitere Schraube weist das Auflageelement auch drei im Abstand voneinnander angeordnete seitliche Durchtrittsöffnungen auf, deren lichte Weite grösser ist als jene Querschnittsfläche, die der Streifen des Schraubenmagazins aufweist, an dem einzelne Schrauben lösbar befestigt sind.In addition to the circular recess for the actuator and the through holes for cooperating with the intermediate piece further screw, the support member also has three spaced apart lateral passage openings whose inside diameter is greater than that cross-sectional area, which has the strip of screw magazine on the individual Screws are releasably attached.
Der Durchmesser der Ausnehmung in dem Auflageelement und der Durchmesser der in das Führungselement eindrehbaren Schrauben sind in der Weise aufeinander abgestimmt, dass eine geringfügige Versetzung des Auflageelementes gegenüber dem Führungselement auch dann möglich ist, wenn die, die Ausnehmung durchsetzende Schraube in eine Gewindebohrung des Führungselementes eingedreht ist. Dieses "Spiel" ist notwendig, damit der Streifen des Schraubenmagazins an der Schraubvorrichtung axial festgelegt werden kann, solange wie das Schraubgerät gegen einen Untergrund gedrückt wird.The diameter of the recess in the support element and the diameter of the screwed into the guide element screws are coordinated in such a way that a slight displacement of the support element relative to the guide element is also possible if the, passing through the recess screw into a threaded bore of the guide element is. This "game" is necessary so that the strip of the screw magazine can be fixed axially to the screwing device, as long as the screwdriver is pressed against a substrate.
Die Herstellung der kreisrunden Ausnehmung, der Durchgangsbohrungen und der Durchtrittsöffnungen in dem Auflageelement ist nur mit grossem Aufwand durchführbar. Ausserdem kann eine axiale Verstellung des Auflageelementes gegenüber dem Führungselement, um unterschiedliche Schraubenmagazine, die sich durch die Länge der Schrauben voneinander unterscheiden, nur dann erfolgen, wenn die mit dem Führungelement und dem Zwischenteil zusammenwirkenden Schrauben mit Hilfe eines geeigneten Werkzeuges entfernt werden.The preparation of the circular recess, the through holes and the openings in the support element can be carried out only with great effort. In addition, an axial adjustment of the support element relative to the guide element to different screw magazines, which differ from each other by the length of the screws, only if the cooperating with the guide element and the intermediate part screws are removed by means of a suitable tool.
Der Erfindung liegt die Aufgabe zugrunde, eine einfache und wirtschaftlich herstellbare Schraubvorrichtung für ein Schraubgerät zu schaffen, bei dem das Auflageelement ohne die Zuhilfenahme eines Werkzeuges entlang des Führungselementes versetzbar sowie an dem Führungselement stufenweise festlegbar ist.The invention has for its object to provide a simple and economically producible screw device for a screwdriver, in which the support element without the aid of a tool along the guide element displaceable and on the guide element is gradually fixed.
Die Lösung dieser Aufgabe erfolgt durch eine Schraubvorrichtung für ein Schraubgerät, welche die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist.
Das erfindungsgemässe, mit dem Führungselement in Verbindung bringbare Stellelement ist von einem Anwender schnell und einfach sowie ohne Werkzeug in eine vorgespannte Freigabestellung bringbar, in der das Auflageelement gegenüber dem Führungselement versetzbar ist. Nach der Versetzung des Auflageelementes in die gewünschte Position federt das Stellelement mit Hilfe der Vorspannkraft wieder zurück in seine Ausgangsstellung, in der es wiederum formschlüssig mit dem Auflageelement zusammenwirkt. Das wirtschaftlich fertigbare Stellelement ist einfach im Aufbau, besteht beispielsweise aus Kunststoff und ist spritztechnisch herstellbar.The solution of this object is achieved by a screw device for a screwdriver, which has the features listed in the characterizing portion of
The inventive, with the guide element can be brought into connection actuator is quickly and easily and without tools in a biased release position can be brought by a user, in which the support element relative to the guide element is displaceable. After the displacement of the support element in the desired position, the actuator with the aid of the biasing force springs back into its original position in which it in turn cooperates positively with the support element. The economically manufacturable control element is simple in construction, for example, consists of plastic and can be produced by injection molding.
Vorzugsweise weist das elastische Stellelement wenigstens einen elastischen Arm auf, der in einer sich senkrecht zur Setzrichtung und senkrecht zur Längserstreckung des Führungskanals erstreckenden Ebene schwenkbar ist und eine Verriegelungszunge aufweist, die zur Verbindung des elastischen Stellelementes mit dem Führungselement mit wenigstens einem Anschlag des Führungselementes formschlüssig in Verbindung bringbar ist. Diese formschlüssige Verbindung wirkt sich insbesonders bei der Montage sämtlicher Teile der Schraubvorrichtung positiv aus, da beispielsweise das Führungselement und das Stellelement gemeinsam in einem Arbeitsgang mit dem Gehäuse der Schraubvorrichtung und einer Verbindungshülse des Schraubgerätes in Verbindung gebracht werden können.Preferably, the elastic actuating element has at least one elastic arm, which is pivotable in a direction perpendicular to the setting direction and perpendicular to the longitudinal extent of the guide channel extending plane and having a locking tongue for the connection of the elastic actuating element with the guide element with at least one stop of the guide element in a form-fitting Connection can be brought. This positive connection has a positive effect particularly in the assembly of all parts of the screwing, as for example, the guide element and the actuator can be brought together in one operation with the housing of the screwing and a connecting sleeve of the screwdriving machine in connection.
Um eine gute Zentrierung eines Eindrehwerkzeuges des Schraubgerätes gegenüber Drehmitnahmeflächen an den Köpfen der Schrauben erreichen zu können, ist der Streifen des streifenförmigen Schraubenmagazins beispielsweise während des Eindrehvorganges gegenüber dem Führungselement festgelegt. Diese Festlegung erfolgt beispielsweise durch ein Klemmen des Streifens in dem Führungskanal. Dies wird vorzugsweise dadurch erreicht, indem das mit dem Führungselement in Verbindung stehende Stellelement parallel zur Setzrichtung begrenzt versetzbar ist, damit eine parallel zur Setzrichtung gemessene Höhe des von dem Stellelement und dem Führungselement gebildeten Führungskanals verändert werden kann.In order to achieve a good centering of a screwing the screwdriver against rotational engagement surfaces on the heads of the screws, the strip of the strip-shaped screw magazine is set, for example, during the driving against the guide element. This determination is made for example by a clamping of the strip in the guide channel. This is preferably achieved in that the adjusting element which is connected to the guide element is limitedly displaceable parallel to the setting direction, so that a height, measured parallel to the setting direction, of the guide channel formed by the adjusting element and the guide element can be changed.
Zweckmässigerweise weist der elastische Arm des Stellelementes einen Verbindungssteg auf, der zur axialen Festlegung des Auflageelementes an dem Führungselement formschlüssig in eine der Ausnehmungen des Auflageelementes ragt. Der Verbindungssteg ist an einem, von einem entgegen der Setzrichtung weisenden Endbereich des elastischen Armes angeordnet und verbindet ein Griffelement mit dem elastischen Arm. Eine parallel zur Setzrichtung gemessene Höhe des Verbindungssteges entspricht der in der gleichen Richtung gemessenen lichten Weite der einzelnen Ausnehmungen an dem Auflageelement. Eine sich parallel zur Längserstreckung des Führungskanals erstreckende Länge des Verbindungssteges entspricht im wesentlichen einer in der gleichen Richtung gemessenen Breite der Ausnehmungen. Da der Verbindungssteg ein Teil des elastischen Armes ist, kann dieser ohne die Zuhilfenahme eines Werkzeuges mit einem geringen Kraftaufwand aus der Ausnehmung in eine vorgespannte Freigabestellung ausgerückt werden, indem der elastische Arm in eine Freigabestellung verschwenkt wird.Conveniently, the elastic arm of the actuating element on a connecting web, which is for the axial fixing of the support element to the guide element positively engages in one of the recesses of the support element. The connecting web is arranged on one, of an opposite to the setting direction facing end portion of the elastic arm and connects a handle member with the elastic arm. A measured parallel to the setting direction height of the connecting web corresponds to the measured in the same direction clear width of the individual recesses on the support element. A parallel to the longitudinal extent of the guide channel extending length of the connecting web corresponds substantially to a measured width in the same direction of the recesses. Since the connecting web is a part of the elastic arm, it can be disengaged without the aid of a tool with a small force from the recess in a biased release position by the elastic arm is pivoted to a release position.
Eine besonders gute formschlüssige Verbindung zwischen dem Stellelement und dem Auflageelement wird zweckmässigerweise dadurch erreicht, indem das elastische Stellelement zwei in der gleichen Ebene zueinander schwenkbare elastische Arme aufweist, die entgegen der Setzrichtung von einem Boden des Stellelementes abragen. Beide elastischen Arme und die Ausnehmungen des Auflageelementes sind beispielsweise an einer Seite des Auflageelementes angeordnet, die von einem Träger des Führungselementes abgewandt ist, der seitlich von dem Führungselement abragt. Die zueinander schwenkbaren elastischen Arme können von einem Anwender ohne grossen Kraftaufwand in eine Freigabestellung verschwenkt werden, in der die beiden Verbindungsstege nicht mehr in die Ausnehmungen des Auflageelementes ragen.A particularly good positive connection between the actuator and the support element is conveniently achieved by the elastic actuator has two in the same plane to each other pivotable elastic arms which protrude against the setting direction of a bottom of the actuating element. Both elastic arms and the recesses of the support element are arranged for example on one side of the support element, which faces away from a support of the guide element, which projects laterally from the guide element. The mutually pivotable elastic arms can be pivoted by a user without much effort into a release position in which the two connecting webs no longer protrude into the recesses of the support element.
Damit sich das Stellelement gegenüber dem Auflageelement nicht verkanten kann, wenn das Auflageelement gegenüber dem Stellelement verschoben wird, weist das elastische Stellelement vorteilhafterweise zwei einander gegenüberliegende, sich parallel zur Setzrichtung erstreckende Führungsleisten auf, die formschlüssig in zwei einander gegenüberliegende Führungsnuten auf der Innenseite des Auflageelementes ragen, die sich ebenfalls parallel zur Setzrichtung erstrecken. Die beiden Führungsleisten sind im Bereich des Bodens angeordnet, damit sie auch dann noch formschlüssig in die Führungsnuten ragen können, wenn die beiden Federarme in eine vorgespannte Freigabestellung gedrückt werden.Thus, the actuator relative to the support element can not tilt when the support member is moved relative to the actuator, the elastic actuator advantageously has two opposing, parallel to the setting direction extending guide rails which protrude positively into two opposing guide grooves on the inside of the support element , which also extend parallel to the setting direction. The two guide rails are arranged in the region of the bottom, so that they can still protrude positively into the guide grooves when the two spring arms are pressed into a preloaded release position.
Um eine exakte parallel zur Setzrichtung verlaufende Führung zwischen dem Gehäuse des Schraubgerätes und dem Auflageelement erreichen zu können, weist das Auflageelement vorzugsweise auf einer Aussenseite zwei einander gegenüberliegende, sich parallel zur Setzrichtung erstreckende, erste Führungsbereiche auf, die formschlüssig mit sich parallel zur Setzrichtung erstreckenden, an einer Innenseite des Gehäuses angeordneten, einander zugewandten Führungskanten zusammenwirken.
Eine ebenfalls genaue, parallel zur Setzrichtung verlaufende Führung zwischen dem Auflageelement und dem Führungselement wird dadurch erreicht, indem das Auflageelement zweckmässigerweise auf einer Innenseite zwei einander zugewandte, parallel zur Setzrichtung verlaufende zweite Führungsbereiche aufweist, die formschlüssig mit einer sich parallel zur Setzrichtung erstreckenden, an einer Aussenseite des Führungselementes angeordneten Führungsrippe zusammenwirken.In order to be able to achieve an exact guidance running parallel to the setting direction between the housing of the screwing device and the support element, the support element preferably has on one outer side two first guide regions extending parallel to the setting direction and extending in a form-fitting manner parallel to the setting direction, arranged on an inner side of the housing, cooperating facing guide edges.
A likewise accurate, parallel to the setting direction guide between the support element and the guide element is achieved by the support element expediently on an inner side two facing, parallel to the setting direction extending second guide portions which form-fitting with a parallel to the setting direction extending at one Outside of the guide element arranged guide rib cooperate.
Zweckmässigerweise ragen in den Führungskanal zwei einander gegenüberliegende Führungsstege, wobei ein erster dieser Führungsstege an dem Führungssteg und ein zweiter Führungssteg an dem Stellelement angeordnet ist. Beide Führungsstege erstrecken sich parallel zur Längserstreckung des Führungskanals und liegen in einer Ebene die parallel zur Setzrichtung verläuft. Mit Hilfe dieser beiden Führungsstege dienen der seitlichen Abstützung des zum Schraubenmagazin gehörenden Streifens an dem die Schrauben lösbar angeordnet sind.Expediently project into the guide channel two opposing guide webs, wherein a first of these guide webs is arranged on the guide web and a second guide web on the actuating element. Both guide webs extend parallel to the longitudinal extent of the guide channel and lie in a plane which is parallel to the setting direction. With the help of these two guide webs serve the lateral support of belonging to the screw magazine strip on which the screws are detachably arranged.
