Abstract
Description
Die Erfindung betrifft ein Lastaufnahmemittel für Förderzeuge, insbesondere Gabelzinke für Flurförderzeuge wie Gabelstapler nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a load handling device for vehicles, especially fork for forklifts such as forklifts according to the preamble of claim 1.
Ein ähnliches Lastaufnahmemittel ist durch die
In der
Um diesen Nachteil auszuschließen, wird weiterhin vorgeschlagen, in der Bohrung des Gabelblattes ein Gewinde vorzusehen, in welches eine Madenschraube eindrehbar ist. Nachteilig ist dabei die umständliche und zeitaufwendige Montage bzw. Demontage der Madenschrauben zu der zusätzlich ein Werkzeug benötigt wird, wobei im rauen Betrieb sowohl der Werkzeugansatz als auch die Gewinde selbst leicht verletzt werden können.To eliminate this disadvantage, it is further proposed to provide a thread in the bore of the fork blade into which a grub screw can be screwed. The disadvantage here is the cumbersome and time-consuming assembly and disassembly of grub screws to the addition of a tool needed In rough operation, both the tool attachment and the threads themselves can be easily injured.
Es wird aber auch schon vorgeschlagen, eine Arretierung vorzusehen, die an der Oberseite der Gabelblattverlängerung oder an den Seiten der Gabelblattverlängerung angeordnete Bohrungen und vertikal bzw. horizontal im Gabelblatt eingelassen mit den Bohrungen zusammenwirkenden Druckstifte aufweisen, die gegen eine Federkraft eindrückbar und wahlweise in zwei Endstellungen arretierbar sind. Sowohl die vertikalen als auch die horizontalen Druckstifte neigen im rauen Betrieb leicht zum Verschmutzen, so dass die Druckstifte in den Bohrungen im Gabelblatt verklemmen und damit ihre Funktion zum Arretieren der Gabelblattverlängerung nicht mehr gewährleistet ist.But it is also proposed to provide a detent, which at the top of the fork blade extension or on the sides of the fork blade extension holes and vertically or horizontally embedded in the fork blade with the holes cooperating pressure pins which can be pressed against a spring force and optionally in two end positions can be locked. Both the vertical and the horizontal pressure pins tend to dirty in rough operation, so that the pressure pins in the holes in the fork blade jam and thus their function to lock the fork blade extension is no longer guaranteed.
Durch die
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Lastaufnahmemittel so weiterzubilden, dass unter Vermeidung der Nachteile der oben geschilderten Arretiervorrichtungen eine kostengünstige, leicht zu bedienende sichere Arretierung einer Gabelblattverlängerung auf einem Gabelblatt möglich ist, ohne dass der Arretierbolzen ungewollt axial beweglich ist.The invention has the object of developing a generic load handling means so that while avoiding the disadvantages of the above Arresting a cost-effective, easy-to-use secure locking a fork blade extension on a fork blade is possible without the locking pin is unintentionally axially movable.
Zur Lösung der Aufgabe wird vorgeschlagen, dass die Bohrung im Gabelblatt eine umlaufende Nut zur Aufnahme von radial aus dem Bolzen heraus bewegbaren Arretiermitteln aufweist, und dass bei in der Nut befindlichen Arretiermitteln diese durch eine lösbare Verriegelung des Bolzens in der Nut zwangsverriegelt sind.To solve the problem it is proposed that the bore in the fork blade has a circumferential groove for receiving radially out of the bolt movable locking means, and that in-groove locking means they are forcibly locked by a releasable locking of the bolt in the groove.
Durch die Zwangsverriegelung ist ein unbeabsichtigtes axiales Verschieben des Bolzens verhindert. Z. B. Steine, die von unten gegen den Bolzen drücken können anders als bei den oben beschriebenen Verriegelungen kein Verschieben des Bolzens bewirken. Der Bolzen bleibt fest in seiner Verriegelungsposition.Due to the positive locking unintentional axial displacement of the bolt is prevented. For example, stones that press against the bolt from below can cause no displacement of the bolt, unlike the latches described above. The bolt remains firmly in its locking position.
Es hat sich bewährt, dass als Betätigungseinrichtung zum Lösen der Verriegelung ein im Bolzen geführter, federbeaufschlagter Entriegelungsbolzen vorgesehen ist, der für eine Entriegelung entgegengesetzt der Entnahmerichtung des Bolzens beaufschlagbar istIt has been proven that a guided in the bolt, spring-loaded unlocking bolt is provided as an actuating device for releasing the lock, which is acted upon for unlocking opposite to the removal direction of the bolt
Sollte eine Entriegelungsbetätigung ungewollt erfolgen, würde damit der Bolzen durch die Entriegelungsbewegung in die Bohrungen hinein, nicht jedoch hinaus verschoben, so dass trotz unbeabsichtigter Betätigung des Entriegelungsbolzens der Bolzen selbst in der Verriegelungsposition verbleiben würde.Should an unlatching operation take place unintentionally, the bolt would thereby be displaced into the holes through the unlocking movement, but not out so that, in spite of unintentional actuation of the unlocking bolt, the bolt would itself remain in the locking position.
Bemerkenswert ist, dass der Bolzen nur bei vollständiger Entriegelung der Arretiermittel in den Bohrungen vertikal beweglich ist. Damit ist eine axiale Bewegung des Bolzens grundsätzlich so lange verhindert, wie nicht der Entriegelungsbolzen vollständig betätigt worden ist. Eine ungewollte teilweise Betätigung des Entriegelungsbolzens würde noch keine Bewegung des Bolzens aus den Bohrungen zulassen.It is noteworthy that the bolt is vertically movable only with complete unlocking of the locking means in the holes. Thus, an axial movement of the bolt is basically prevented as long as not the unlocking pin has been fully actuated. An unwanted partial actuation of the release bolt would not allow movement of the bolt from the holes.
Zweckmäßig ist, dass der Entriegelungsbolzen bei in die Bohrungen eingesetztem Bolzen durch die Feder nur in die Ausgangsstellung zurückgeführt werden kann, wenn sich die Arretiermittel in der Nut in Arretierposition befinden, und dass eine optische Kontrolle für die Position des Entriegelungsbolzens vorgesehen ist.It is expedient that the unlocking bolt can be returned to the bolt inserted into the holes by the spring only in the starting position when the locking means are in the groove in the locking position, and that a visual control is provided for the position of the release bolt.
Ist der Bolzen z. B. vollständig in die Bohrungen eingeführt worden, befindet sich jedoch in der Nut eine Verschmutzung, so können die Arretiermittel nicht in Nut vordringen. Damit kann aber auch der Entriegelungsbolzen durch die Feder nicht in seine Ausgangsstellung zurückkehren. Vorteilhaft ist dabei, wenn im Bereich des Sichtbarwerdens durch farbige Markierungen, z.B. Farbringe so lange signalisiert wird, wie der Entriegelungsbolzen noch nicht in seine Ausgangsstellung zurückgeführt ist.If the bolt z. B. has been completely introduced into the holes, but there is a contamination in the groove, so the locking means can not penetrate into the groove. But so that the unlocking bolt can not return by the spring in its initial position. It is advantageous if, in the region of being visible, colored markings, e.g. Color rings is signaled as long as the release bolt is not returned to its original position.
Eine besonders einfache Handhabung des Bolzens ergibt sich dadurch, dass der Bolzen durch eine Einhandbedienung in die Bohrungen einführbar ist. Durch einfaches Einsetzen des Bolzens in die Bohrung und anschließendes Drücken auf den Entriegelungsbolzen kann der Bolzen vollständig in die Bohrung eingeführt werden. Um dagegen ein ungewolltes Entnehmen des Bolzens aus den Bohrungen zu verhindern, wird vorgeschlagen, dass der Bolzen nur durch eine Zweihandbedienung aus den Bohrungen entnehmbar ist. Mit der einen Hand muss der Entriegelungsbolzen betätigt werden. Mit der zweiten Hand muss entgegen der Entriegelungsbewegung der Bolzen aus der Bohrung herausgeführt werden. Damit sind eine sehr einfache Handhabung beim Einführen und eine größtmögliche Sicherheit beim Entnehmen des Bolzens gewährleistet.A particularly simple handling of the bolt results from the fact that the bolt can be inserted by a one-hand operation in the holes. By simply inserting the bolt into the hole and then pressing on the release bolt, the bolt can be fully inserted into the hole. In order to prevent unwanted removal of the bolt from the holes, it is proposed that the bolt can be removed only by a two-handed operation of the holes. With one hand, the release bolt must be pressed. With the second hand, contrary to the unlocking movement, the bolt must be led out of the bore. This ensures a very easy handling during insertion and maximum safety when removing the bolt.
Bemerkenswert ist, dass der Bolzen stufenförmig ausgebildet ist, und dass der Absatz des Bolzens zur Entlastung der Arretiermittel in axialer Richtung beiträgt Durch den Absatz wird bei einer Druckbewegung auf den Bolzen die Kraft in den Absatz eingeleitet. Eine zusätzliche Belastung der Arretiermittel erfolgt nicht.It is noteworthy that the bolt is step-shaped, and that the shoulder of the bolt contributes to the relief of the locking means in the axial direction. By the paragraph, the force is introduced into the shoulder during a pressure movement on the bolt. An additional burden of locking does not occur.
Ein weiterer Vorteil ergibt sich dadurch, dass der Durchmesser des oberen Bundes des Bolzens in seiner vertikalen Ausdehnung die Materialstärke der Gabelblattverlängerung übersteigt. Durch die beanspruchte Ausgestaltung des oberen Bundes des Bolzens wird erreicht, dass von der Gabelblattverlängerung ausgehende Scherkräfte optimal ins Gabelblatt eingeleitet werden können. Selbst wenn der Bolzen noch nicht vollständig eingerastet sein sollte, könnten durch die Wahl der Größe des Bundes eventuell schon auftretende Scherkräfte noch optimal in das Gabelblatt eingeleitet werden.Another advantage results from the fact that the diameter of the upper collar of the bolt in its vertical extent exceeds the material thickness of the fork blade extension. Due to the claimed design of the upper collar of the bolt is achieved that outgoing from the fork blade extension shear forces can be optimally introduced into the fork blade. Even if the bolt should not be fully engaged, could be introduced optimally in the fork blade by the choice of the size of the federal possibly already occurring shear forces.
Nachahmenswert ist, dass zumindest die Nut in einer Hülse eingearbeitet ist, welche fest mit der Bohrung des Gabelblattes verbunden ist. Durch eine derartig eingesetzte Hülse wird eine optimale Werkstoffkombination zwischen Bolzen und Hülse und insbesondere auch zwischen den Arretiermitteln und der Hülse gewährleistet.It is worthy of imitation that at least the groove is incorporated in a sleeve, which is firmly connected to the bore of the fork blade. By such a sleeve used an optimal combination of materials between the bolt and sleeve and in particular between the locking means and the sleeve is ensured.
