Description

Die Erfindung betrifft Lastaufnahmemittel für Förderzeuge, insbesondere Gabeln für Flurförderzeuge, mit mindestens einer Zinke, die einen Gabelrücken und ein mit diesem verbundenes Gabelblatt aufweist, wobei am dem Gabelrücken abgewandten freien Ende des Gabelblattes ein Klappschuh drehbar gelagert ist.The invention relates to load handling equipment for trucks, especially forks for trucks, with at least one prong, which has a fork back and a fork blade connected thereto, wherein on the fork back facing away from the free end of the fork blade, a folding shoe is rotatably mounted.

Derartige Gabelzinken mit integrierten Klappschuhen bzw. -spitzen dienen dazu, Ladegut vor Beschädigungen zu schützen. Bei einer normalen Benutzung liegt der Klappschuh auf dem Gabelblatt auf, und kann z.B. in die dafür vorgesehenen Öffnungen von Paletten eingefahren werden. Bei einem ungewollten Kontakt der Spitze des Klappschuhs mit dem Ladegut oder der Palette klappt der Klappschuh um. Er wird dabei um ca. 90° verschwenkt und vergrößert dabei die Kontaktfläche der Gabelzinke zum Ladegut. Hierdurch wird die Flächenpressung kleiner und ein Durchbohren bzw. Beschädigen des Ladeguts wird verhindert.Such forks with integrated Klappschuhen or tips are used to protect cargo from damage. In normal use, the flap shoe rests on the fork blade, and may e.g. be retracted in the designated openings of pallets. In the event of unwanted contact of the tip of the folding shoe with the load or the pallet, the folding shoe folds over. It is pivoted about 90 ° and thereby increases the contact surface of the fork to load. As a result, the surface pressure is smaller and drilling through or damaging the cargo is prevented.

Eine derartige Gabelzinke mit integriertem Klappschuh ist durch die WO 2011/048576 A1 bekannt geworden. Der Klappschuh ist hier jedoch so an der Spitze des Gabelblatts befestigt, dass nicht jede ungewollte Berührung der Klappschuhspitze mit dem Ladegut auch zu einem Umlegen des Klappschuhs führt. Kommt es zu Kräften auf den Klappschuh, die nicht exakt in Längsrichtung zum Gabelblatt wirken, besteht die Gefahr, dass der Klappschuh nicht sicher umklappt. Die Spitze des Gabelzinkens kann sich in das Ladegut bohren. Handelt es sich dabei z. B. um mit Treibgas gefüllte Dosen, kann es zu Explosionen und größeren Schäden, auch Personenschäden kommen.Such a fork with integrated folding shoe is through the WO 2011/048576 A1 known. However, the folding shoe is attached to the tip of the fork blade so that not every unwanted contact of the folding shoe tip with the load also leads to a folding of the folding shoe. If there are forces on the folding shoe that do not act exactly in the longitudinal direction of the fork blade, there is a risk that the folding shoe does not fold over safely. The tip of the fork tine can drill into the load. Is it z. As to be filled with propellant gas cans, it can cause explosions and major damage, including personal injury.

Durch die DE 10 2011 121 329 A1 ist eine Staplergabel bekannt geworden, die mit einer Stoßdämpfervorrichtung ausgestattet ist, die in Längsrichtung der Gabelzinken einwirkende mechanische Energie zumindest teilweise in innere Energie umwandelt. Eine Vergrößerung der Fläche der Gabelspitze gegenüber dem Ladegut ist nicht vorgesehen. Nach Umwandlung der mechanischen Energie in innere Energie fährt die Gabelspitze ungewollt in das Ladegut, wodurch es zu hohen wirtschaftlichen Schäden und ggf. zu Umweltschäden und Personengefährdung kommen kann.By the DE 10 2011 121 329 A1 For example, there is known a forklift fork equipped with a shock absorber device which at least partially converts mechanical energy applied in the longitudinal direction of the forks into internal energy. An enlargement of the surface of the fork tip against the load is not provided. After conversion of the mechanical energy into internal energy, the fork tip moves unintentionally into the load, which can lead to high economic damage and possibly environmental damage and personal injury.

Der Erfindung liegt die Aufgabe zugrunde, ein Lastaufnahmemittel für Förderzeuge so weiterzubilden, dass es bei Auftreten von Kräften mit einer Kraftkomponente in Richtung auf das Gabelblatt sicher zum Umklappen des Gabelschuhs kommt, so dass das Ladegut nicht beschädigt werden kann und Schäden, auch Umweltschäden und Personenschäden ausgeschlossen sind.The invention has the object of providing a load handling equipment for vehicles so that it comes safely to fold the fork shoe when forces with a force component in the direction of the fork blade, so that the load can not be damaged and damage, including environmental damage and personal injury excluded are.

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass im Bereich des freien Endes des Gabelblattes mindestens eine sich längs des Gabelblattes erstreckende Längsführung für ein zumindest bereichsweise vom freien Ende des Gabelblattes abstehendes geführtes Element vorgesehen ist, dass der Klappschuh am abstehenden Bereich des geführten Elements drehbar gelagert ist, dass das Gabelblatt und der Gabelschuh mindestens je eine, in zumindest geringfügig unterschiedlichen Ebenen angeordnete Gelenkverbindung aufweist, und dass zwischen der Gelenkverbindung des Gabelblatts und der Gelenkverbindung des Klappschuhs mindestens eine Schubstange angeordnet ist.To solve this problem, it is proposed that in the region of the free end of the fork blade, at least one longitudinal guide extending along the fork blade be provided for a guided element projecting at least partially from the free end of the fork blade, such that the folding shoe is rotatably mounted on the protruding region of the guided element in that the fork blade and the fork shoe have at least one articulated connection arranged in at least slightly different planes, and at least one push rod is arranged between the articulated connection of the fork blade and the articulated connection of the folding shoe.

Auf den Klappschuh einwirkende Kräfte mit einer Komponente in Richtung auf das Gabelblatt bewirken eine Verschiebung des geführten Elements in seiner Führung. Die zwischen Gabelblatt und Gabelschuh angeordnete Schubstange kann diese Längsbewegung jedoch nicht ausführen. Aufgrund der in unterschiedlichen Ebenen angeordneten Gelenkverbindungen bewirkt die Schubstange jedoch, dass der Klappschuh um die Drehlagerung an der Spitze des geführten Elementes zwangsverschwenkt wird, und der Klappschuh aus seiner Ruhestellung in eine Schutzstellung geklappt wird. Durch die zunehmende Wegverkürzung des Drehpunkts zwischen geführtem Element und Klappschuh gegenüber den Befestigungspunkten der Schubstangen an dem Gabelblatt, hebt die Schubstange damit den Klappschuh zu einer drehenden Bewegung an.Forces acting on the flap shoe with a component in the direction of the fork blade cause a displacement of the guided element in his leadership. However, arranged between fork blade and fork shoe push rod can not perform this longitudinal movement. However, due to arranged in different planes articulated joints causes the push rod that the Folding shoe is zwangsverschwenkt about the pivot bearing at the top of the guided element, and the folding shoe is folded from its rest position to a protective position. Due to the increasing shortening of the pivot point between the guided element and the folding shoe with respect to the attachment points of the push rods on the fork blade, the push rod thus lifts the folding shoe to a rotating movement.

Damit vergrößert sich die auf das Ladegut einwirkende Fläche von der Spitze des Klappschuhs mit ihrer kleinen Fläche hin zu dem großen Rücken des Klappschuhs, der nunmehr auf das Ladegut einwirkt. Dadurch kann der Klappschuh nicht mehr ins Ladegut eindringen und hier zu Schäden führen.Thus, the area acting on the load surface increases from the top of the folding shoe with its small area towards the large back of the folding shoe, which now acts on the load. As a result, the folding shoe can no longer penetrate into the load and cause damage here.

Vorteilhaft ist, dass dem geführten Element zumindest ein Federsystem zugeordnet ist, welches das geführte Element vom Gabelrücken weg vorzuspannen vermag.It is advantageous that the guided element is assigned at least one spring system which is able to bias the guided element away from the fork back.

Dieses Federsystem bewirkt einerseits, dass nachdem die Kraft mit mindestens einer Komponente in Richtung auf das Gabelblatt nachlässt, dass der Klappschuh auch wieder zurückgeklappt werden kann. Andererseits bewirkt das Federsystem, dass der Klappschuh in eine Richtung vorgespannt ist. Es kann zu keinem ungewollten Aufstellen des Klappschuhs und ggf. Klappern des Klappschuhs auf dem Gabelblatt während des Befahrens des Förderzeuges auf z. B. unebenem Untergrund kommen.This spring system causes on the one hand, after the force with at least one component in the direction of the fork blade decreases that the folding shoe can also be folded back again. On the other hand, the spring system causes the flap shoe to be biased in one direction. There may be no unwanted installation of the folding shoe and possibly rattling of the folding shoe on the fork blade during the access of the truck on z. B. uneven ground.

Es hat sich bewehrt, als Federsystem eine Druckfeder und/oder eine hydraulische und/oder eine pneumatische Feder vorzusehen.It has been reinforced to provide a compression spring and / or a hydraulic and / or pneumatic spring as the spring system.

Die Federn können leicht zwischen der Längsführung und dem geführten Element angeordnet werden, um die gewünschte Vorspannung zu erzeugen.The springs can be easily placed between the longitudinal guide and the guided element to produce the desired preload.

Bemerkenswert ist, dass es sich bei der Längsführung um eine Flachführung und/oder eine V-Führung und/oder eine Schwalbenschwanzführung und/oder eine Rundführung handelt.It is noteworthy that the longitudinal guide is a flat guide and / or a V-guide and / or a dovetail guide and / or a round guide.

Die Führungen könnten geschützt im Gabelblatt untergebracht sein, so dass nur ein kleiner Bereich des freien Endes des geführten Elements mit seiner Drehachse aus dem Gabelblatt hervorragt. Dadurch sind die Führungen vor Schmutz und eventuellem Verschleiß geschützt.The guides could be housed protected in the fork blade, so that only a small portion of the free end of the guided element protrudes with its axis of rotation of the fork blade. As a result, the guides are protected from dirt and possible wear.

Zum Schutz der Führungen trägt auch bei, wenn der Klappschuh im Querschnitt die Form eines mit seiner Öffnung nach unten weisenden U besitzt und der Klappschuh in seiner Ruhestellung das freie Ende des Gabelblatts im Wesentlichen umgreift.To protect the guides also contributes when the folding shoe in cross-section has the shape of a pointing downwards with its opening U and the folding shoe in its rest position, the free end of the fork blade substantially surrounds.

Bedeutsam ist, dass jedem der beiden Schenkel des U-förmigen Klappschuhs eine Schubstange zugeordnet ist und dass die Schubstangen zusammen mit dem in der Längsführung geführten Element und dem Klappschuh ein Parallelogramm-Getriebe bildet.It is important that each of the two legs of the U-shaped clip shoe is associated with a push rod and that the push rods together with the guided in the longitudinal guide element and the clip shoe forms a parallelogram transmission.

Dadurch ist ein sicheres, verkantungsfreies Aufklappen des Klappschuhs bei Auftreten von Kräften mit Komponenten in Richtung auf das Gabelblatt gewährleistet.This ensures a secure, tilt-free unfolding of the folding shoe when forces with components in the direction of the fork blade occur.

Figur 1 zeigt eine Gabel 1, bestehend aus einem Gabelrücken 2 und einem Gabelblatt 3. Am Gabelrücken sind Gabelhaken 4, 4' vorgesehen, mittels derer die Gabel 1 an einem nicht gezeigtem Gabelträger eines Förderzeuges befestigt werden kann. An der Spitze des Gabelblattes 3 ist ein Klappschuh 6 angeordnet. FIG. 1 shows a fork 1, consisting of a fork back 2 and a fork blade 3. At the fork back fork hooks 4, 4 'are provided by means of which the fork 1 can be attached to a not shown Gabelträger a conveyor. At the top of the fork blade 3, a folding shoe 6 is arranged.

Figur 2 ist die gleiche erfindungsgemäße Gabel 1 entnehmbar, bei der jedoch der Klappschuh 6 aus der Ruhestellung in Figur 1 in die Wirkstellung nach Figur 2 verschwenkt ist. In Figur 2 sind zudem die hintereinander liegenden Schubstangen 7 zu erkennen. FIG. 2 the same inventive fork 1 can be removed, but in which the folding shoe 6 from the rest position in FIG. 1 into the active position FIG. 2 is pivoted. In FIG. 2 are also the successive push rods 7 can be seen.

Figur 3 zeigt nunmehr das Gabelblatt 3 in abgebrochener Darstellung. Im Gabelblatt 3 ist eine Längsführung 8 vorgesehen, in der ein geführtes Element 9 längsbeweglich gelagert ist. An der Spitze 10 des geführten Elements 9 ist der Klappschuh 6 über eine Drehachse 11 drehbar gelagert. Das geführte Element 9 ist über ein Federsystem 12 in Richtung vom Gabelblatt 3 fort vorgespannt. Die Schubstange 7, die einerseits an einem Gelenk 13 am Gabelblatt 3 gelenkig befestigt ist und andererseits über ein zweites Gelenk 14 mit dem Klappschuh 6 gelenkig in Verbindung steht, bewirkt, dass das geführte Element 9 nicht aus der Längsführung 8 herausbewegt werden kann. FIG. 3 now shows the fork blade 3 in a broken view. In the fork blade 3, a longitudinal guide 8 is provided, in which a guided element 9 is mounted longitudinally movable. At the top 10 of the guided element 9, the folding shoe 6 is rotatably supported via a rotation axis 11. The guided element 9 is biased by a spring system 12 in the direction of the fork blade 3 away. The push rod 7, which is articulated on the one hand to a joint 13 on the fork blade 3 and on the other hand articulated via a second joint 14 with the folding shoe 6, causes the guided element 9 can not be moved out of the longitudinal guide 8.

Wesentlich ist, dass das Gelenk 13 unterhalb der Ebene, in der das Gelenk 14 angeordnet ist, positioniert ist, so dass wenn auf die Spitze 5 des Klappschuhs 6 eine Kraftkomponente in Richtung auf das Gabelblatt 3 ausgeübt wird, die das geführte Element 9 in der Längsführung 8 gegen die Kraft des Federsystems 12 längs bewegt, die versetzt gelagerte Schubstange 7 eine Verschwenkbewegung des Klappschuhs 6 hervorruft.It is essential that the joint 13 is positioned below the plane in which the joint 14 is arranged so that when a force component is exerted on the tip 5 of the snap shoe 6 in the direction of the fork blade 3, the guided element 9 in the Longitudinal guide 8 against the force of the spring system 12 moves longitudinally, the staggered thrust rod 7 causes a pivoting movement of the folding shoe 6.

Figur 4 zeigt, wie der Klappschuh 6 schwenkbewegt wurde. Das Federsystem 12 ist zusammengepresst dargestellt. Das geführte Element 9 ist weitestgehend in die Längsführung 8 eingefahren und die Schubstange 7 hat sich aufgestellt. FIG. 4 shows how the folding shoe 6 has been pivoted. The spring system 12 is shown compressed. The guided element 9 is largely retracted into the longitudinal guide 8 and the push rod 7 has been set up.

Dabei bilden die Schubstange 7 bzw. die zwei hintereinander angeordneten Schubstangen 7 und das geführte Element 9 zusammen mit dem Klappschuh ein Parallelogramm-Getriebe, welches stets ein sicheres Aufstellen des Klappschuhs 6 bewirkt.In this case, the push rod 7 and the two successively arranged push rods 7 and the guided element 9 together with the folding shoe a parallelogram gear, which always causes a safe placement of the folding shoe 6.
