Definitions
- the present invention relates to a vehicle body, in particular for trucks, according to the preamble of claim 1.
- the DE 39 41 084 C2 discloses a spring break protection for gate shafts of sectional doors, in which a blocking plate is connected to a door shaft, which has distributed receiving bores for a locking pin.
- the locking pin is mounted radially displaceable to the door shaft in a holding plate and, when triggered, can engage in the radial blind bores of the locking wheel in order to stop the door shaft.
- Such a spring break protection can be used in sectional doors for garages, but is not suitable for a vehicle body, for example in trucks.
- the problem with vehicle bodies is that they are exposed to the weather and become contaminated, so that blind holes can easily become blocked.
- the EP 803 626 A1 discloses a lifting device for a vertically movable gate, with a driven reel which is coupled to a motor via an intermediate element.
- the intermediate member is attached to a fixed bracket of the reel-up with a certain rotational play and a pawl is arranged near the reel-up in order to be able to pivot into a certain position, in which it interacts with a stop of the reel-up if the intermediate member interacts due to a failure the gate retention device rotates.
- the vehicle body according to the invention comprises a sectional door, in which a spring breakage protection is provided on a spring shaft, which has a pinion connected to the spring shaft and a pivotable pretensioned locking lever which can be brought into engagement with the pinion to lock a rotary movement of the spring, one end of which Spring is held on an adapter which is pivotally held on a holder and keeps the locking lever disengaged from the pinion in a position biased by the spring and releases the locking lever when the spring breaks so that it can be brought into engagement with the pinion.
- the spring shaft and the sectional door can be fixed mechanically reliably in the event of a spring break, since the adapter can be pivoted from a position in which the locking lever is blocked in order to bring the locking lever into engagement with the pinion, so that a tension spring, the locking lever reliably ensures that the spring shaft is fixed.
- This mechanical solution can reliably fix the sectional door even when there is considerable vibration during operation, even if the components are exposed to weather conditions and contamination during operation.
- the spring break protection can be designed in a particularly compact design.
- the adapter has an opening in which the pinion is received.
- the pinion and the adapter viewed in the longitudinal direction of the spring shaft, can be arranged essentially in the same plane.
- the adapter has two arc-shaped elongated holes, into each of which a bolt is inserted for mounting the adapter. The adapter can then be rotated from a first position, in which the locking lever is locked, into a release position, in which the locking lever engages with the pinion.
- a holder can be of an angular design, with a first section of the holder being fixed to an upper panel of the vehicle body.
- the holder is arranged in a central region of the spring shaft and has a bushing for the spring shaft.
- the pinion has an opening for the passage of the spring shaft, so that the pinion and possibly the adapter are held captively on the spring shaft.
- the locking lever is arranged in a receptacle between the adapter and a section of the holder.
- the locking lever can be rotatably mounted on an axis on the section of the holder and biased towards the pinion by a tension spring be.
- the spring break protection can be preassembled on the holder.
- the spring shaft is preferably connected on opposite sides to a cable drum for pulling up the panels of the sectional door.
- the spring shaft can preferably still be rotated in one direction in order to pull up the panels.
- the spring shaft is locked in the opposite direction by the locking lever.
- a vehicle body not shown, for example in the case of a truck, comprises a loading space which is closed at the rear by a sectional door 1.
- the remaining components of the vehicle body, the side walls, the ceiling and the floor have been omitted here for the sake of simplicity.
- the sectional door 1 comprises a plurality of panels 2 which are pivotably mounted on one another and which are guided on opposite sides via running parts 3.
- each barrel part 3 is provided with a bearing into which an axis 4 with a roller 5 is inserted.
- the rollers 5 of the running parts 3 serve to guide the panels 2 along a guide which has a vertical guide rail 6 and a horizontal guide rail 70 which are connected to one another via an arcuate section 8.
- the guidance of the vertical guide rail 6 and the upper horizontal guide rail 70 is shown, in which the rollers 5 of the running parts 3 are guided.
- the panels 2 of the sectional door can be moved from a vertical position, in which an opening is closed, to a horizontal position in the upper region of the vehicle body in order to expose a loading opening.
- a spring shaft 7 is mounted on an upper rigid panel 12, which is connected to a cable drum 15 on opposite sides.
- a rope 40 is wound onto the rope drum 15 ( Figure 2 ), which is fixed to the bottom panel 2 via a cable anchor plate 41, so that the sectional door can be pulled up by rotating the cable drum 15.
- a spring 10 is provided on the spring shaft 7, wherein a plurality of springs 10 can also be provided distributed over the length of the spring shaft 7.
- the spring 10 is designed as a torsion spring and is arranged in a central region of the spring shaft 7. One end of the spring 10 is fixed to a holder 11 which is fixed to the panel 12. The opposite end of the spring 10 is fixed to a spring break device 13 which is arranged on a holder 14.
- the spring shaft 7 is fixed adjacent to the cable drums 15 via bearings 9 on the uppermost panel 12.
- the spring break safety device 13 is shown.
- the spring break safety device 13 is held on an angular holder 14 which is fixed to the uppermost panel 12 with a first section 24.
- an adapter 21 is pivotally mounted, in which a pinion 16 is received.
- the pinion 16 is non-rotatably connected to the spring shaft 7 and has on its outer circumference a plurality of teeth 17 which are oriented at an angle to the radial and can be brought into engagement with a pawl 19 of a locking lever 18.
- the locking lever 18 is rotatably mounted on the protruding section 25 and is biased towards the pinion 16 via a spring (not shown).
- a bushing 26 for the spring shaft 7 is formed on the projecting section 25 of the holder 14, so that the spring shaft is passed through an opening 27 and the bushing 26.
- the adapter 21 has an opening 28 in which the pinion 16 is inserted.
- arcuate elongated holes 22 are recessed into which a bolt 33 for inserting the adapter 21 in a pivotable manner is inserted.
- One end of the spring 10 is fixed to the adapter 21 so that it is in a locking position in which the locking lever 18 is held out of engagement by the pinion 16. If the spring 10 breaks, no more force is exerted on the adapter 21, so that it can pivot relative to the holder 14, so that the locking lever 18 engages with the pinion 16 by the force of a tension spring, so that the pinion 16 is locked against rotation in a first direction, but can be rotated in an opposite second direction. This prevents the panels 2 of the sectional door 1 from falling off, while the panels 2 can be raised in the opposite direction by rotating the spring shaft 7.
- the locking lever 18 then latches on the teeth 17 of the pinion 16.
- the spring break safety device 13 is shown in detail.
- the pinion 16 is received in the opening 28 of the adapter 21 and has means for the rotationally fixed fixing of the spring shaft 7, in particular by means of screws or bolts.
- the adapter 21 has a receptacle for the locking lever 18 adjacent to the opening 28.
- a side wall of the receptacle forms a stop 29 which acts in the locking position on the locking lever 18 in order to keep it out of engagement with the pinion 16 in a position.
- the locking lever 18 is received between a portion 25 of the holder 14 and the adapter 21 protected.
- the bolts 33 are sleeve-shaped and are fixed to the section 25 by means of screws 23. As a result, the adapter 21 can be pivoted along the bolts 33 via the arcuate elongated holes 22.
- the locking lever 18 is rotatably mounted on the section 25 of the holder 14, for which purpose an opening 34 is formed in the locking lever 18, into which sleeves 20 and 31 are inserted, which are penetrated by a screw 30 which extends into an opening 32 of the section 25 is inserted.
- the locking lever 18 can thus be pivoted about the axis formed by the sleeves 20 and 31 and is biased to the pinion 16 by a spring, not shown here.
- a portion of the locking lever 18 lies against the stop 29 of the adapter in the unlocked position, and when the adapter 21 is pivoted, the locking lever 18 is pivoted toward the pinion, so that the locking pawl 19 comes into engagement with the teeth 17.
- only one spring 10 is arranged along the spring shaft 7. It is also possible to position a plurality of springs 10 along the spring shaft 7, in which case a spring break device 13 according to FIGS Figures 5 and 6 can be provided.

Description
Die vorliegende Erfindung betrifft einen Fahrzeugaufbau, insbesondere fĂ¼r LKWs, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a vehicle body, in particular for trucks, according to the preamble of claim 1.
Die

Die
Es ist daher Aufgabe der vorliegenden Erfindung, einen Fahrzeugaufbau mit einem Sektionaltor zu schaffen, bei dem eine zuverlässig und kompakt aufgebaute Federbruchsicherung vorgesehen ist.It is therefore an object of the present invention to provide a vehicle body with a sectional door in which a reliable and compact spring break device is provided.
Diese Aufgabe wird mit einem Fahrzeugaufbau mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a vehicle body with the features of claim 1.
Der erfindungsgemĂ¤ĂŸe Fahrzeugaufbau umfasst ein Sektionaltor, bei dem an einer Federwelle eine Federbruchsicherung vorgesehen ist, die ein mit der Federwelle verbundenes Ritzel und einen verschwenkbaren vorgespannten Sperrhebel aufweist, der zum Sperren einer Drehbewegung der Feder in Eingriff mit dem Ritzel bringbar ist, wobei ein Ende der Feder an einem Adapter gehalten ist, der verschwenkbar an einem Halter gehalten ist und in einer durch die Feder vorgespannten Position den Sperrhebel auĂŸer Eingriff von dem Ritzel hält und bei einem Bruch der Feder den Sperrhebel freigibt, damit dieser in Eingriff mit dem Ritzel bringbar ist. Dadurch kann eine mechanisch zuverlässige Festsetzung der Federwelle und des Sektionaltores bei einem Bruch der Feder erfolgen, da der Adapter von einer Position, in der der Sperrhebel blockiert ist, verschwenkt werden kann, um den Sperrhebel in Eingriff mit dem Ritzel zu bringen, so dass aufgrund einer Spannfeder der Sperrhebel zuverlässig fĂ¼r ein Festsetzen der Federwelle sorgt. Diese mechanische Lösung kann auch bei erheblichen Vibrationen während eines Fahrbetriebes zuverlässig das Sektionaltor festsetzen, auch wenn im Betrieb die Bauteile WitterungseinflĂ¼ssen und einer Verschmutzung ausgesetzt sind. Zudem kann die Federbruchsicherung in besonders kompakter Bauweise ausgebildet sein.The vehicle body according to the invention comprises a sectional door, in which a spring breakage protection is provided on a spring shaft, which has a pinion connected to the spring shaft and a pivotable pretensioned locking lever which can be brought into engagement with the pinion to lock a rotary movement of the spring, one end of which Spring is held on an adapter which is pivotally held on a holder and keeps the locking lever disengaged from the pinion in a position biased by the spring and releases the locking lever when the spring breaks so that it can be brought into engagement with the pinion. This allows the spring shaft and the sectional door to be fixed mechanically reliably in the event of a spring break, since the adapter can be pivoted from a position in which the locking lever is blocked in order to bring the locking lever into engagement with the pinion, so that a tension spring, the locking lever reliably ensures that the spring shaft is fixed. This mechanical solution can reliably fix the sectional door even when there is considerable vibration during operation, even if the components are exposed to weather conditions and contamination during operation. In addition, the spring break protection can be designed in a particularly compact design.
ErfindungsgemĂ¤ĂŸ weist der Adapter eine Ă–ffnung auf, in der das Ritzel aufgenommen ist. Dadurch können das Ritzel und der Adapter in Längsrichtung der Federwelle gesehen im Wesentlichen in der gleichen Ebene angeordnet sein. FĂ¼r eine zuverlässige Lagerung des Adapters weist dieser zwei bogenförmige Langlöcher auf, in die zur Lagerung des Adapters jeweils ein Bolzen eingefĂ¼gt ist. Dann kann der Adapter von einer ersten Position, in der der Sperrhebel blockiert ist, in eine Freigabeposition gedreht werden, in der der Sperrhebel in Eingriff mit dem Ritzel gelangt.According to the invention, the adapter has an opening in which the pinion is received. As a result, the pinion and the adapter, viewed in the longitudinal direction of the spring shaft, can be arranged essentially in the same plane. For a reliable mounting of the adapter, it has two arc-shaped elongated holes, into each of which a bolt is inserted for mounting the adapter. The adapter can then be rotated from a first position, in which the locking lever is locked, into a release position, in which the locking lever engages with the pinion.
FĂ¼r eine einfache Fixierung der Federbruchsicherung kann ein Halter winkelförmig ausgebildet sein, wobei ein erster Abschnitt des Halters an einem oberen Paneel des Fahrzeugaufbaus festgelegt ist.For a simple fixation of the spring break protection, a holder can be of an angular design, with a first section of the holder being fixed to an upper panel of the vehicle body.
Der Halter ist in einem mittleren Bereich der Federwelle angeordnet sein und weist an eine DurchfĂ¼hrung fĂ¼r die Federwelle auf. Dadurch kann eine Federwelle mit nur einer einzigen Federbruchsicherung festgelegt werden, auch wenn an beiden Enden der Federwelle durch Seiltrommeln Torsionskräfte aufgebracht werden.The holder is arranged in a central region of the spring shaft and has a bushing for the spring shaft. As a result, a spring shaft can be fixed with only a single spring break protection, even if torsional forces are applied to both ends of the spring shaft by cable drums.
In einer weiteren Ausgestaltung der Erfindung weist das Ritzel eine Ă–ffnung zur DurchfĂ¼hrung der Federwelle auf, so dass das Ritzel und gegebenenfalls der Adapter unverlierbar an der Federwelle gehalten sind.In a further embodiment of the invention, the pinion has an opening for the passage of the spring shaft, so that the pinion and possibly the adapter are held captively on the spring shaft.
FĂ¼r einen besonders kompakten Aufbau ist der Sperrhebel in einer Aufnahme zwischen dem Adapter und einem Abschnitt des Halters angeordnet. Der Sperrhebel kann dabei an einer Achse an dem Abschnitt des Halters drehbar gelagert sein und durch eine Spannfeder zu dem Ritzel hin vorgespannt sein. Dadurch kann die Federbruchsicherung an dem Halter vormontiert werden.For a particularly compact construction, the locking lever is arranged in a receptacle between the adapter and a section of the holder. The locking lever can be rotatably mounted on an axis on the section of the holder and biased towards the pinion by a tension spring be. As a result, the spring break protection can be preassembled on the holder.
Vorzugsweise ist die Federwelle an gegenĂ¼berliegenden Seiten mit einer Seiltrommel zum Hochziehen der Paneele des Sektionaltores verbunden. Bei einem Eingriff des Sperrhebels in das Ritzel kann vorzugsweise die Federwelle in eine Richtung noch gedreht werden, um die Paneele hochzuziehen. In die gegenĂ¼berliegende Richtung ist die Federwelle durch den Sperrhebel gesperrt.The spring shaft is preferably connected on opposite sides to a cable drum for pulling up the panels of the sectional door. When the locking lever engages in the pinion, the spring shaft can preferably still be rotated in one direction in order to pull up the panels. The spring shaft is locked in the opposite direction by the locking lever.

Ein nicht näher dargestellter Fahrzeugaufbau, beispielsweise bei einem LKW, umfasst einen Laderaum, der rĂ¼ckseitig durch ein Sektionaltor 1 verschlossen ist. Die Ă¼brigen Bestandteile des Fahrzeugaufbaus, die Seitenwände, die Decke sowie der Boden sind hier zur vereinfachten Darstellung weggelassen worden.A vehicle body, not shown, for example in the case of a truck, comprises a loading space which is closed at the rear by a sectional door 1. The remaining components of the vehicle body, the side walls, the ceiling and the floor have been omitted here for the sake of simplicity.
Das Sektionaltor 1 umfasst mehrere verschwenkbar aneinander gelagerte Paneele 2, die an gegenĂ¼berliegenden Seiten Ă¼ber Laufteile 3 gefĂ¼hrt sind. Wie der
Zum Bewegen der Paneele 2 ist an einem oberen starren Paneel 12 eine Federwelle 7 montiert, die an gegenĂ¼berliegenden Seiten mit einer Seiltrommel 15 verbunden ist. Auf die Seiltrommel 15 ist ein Seil 40 aufgewickelt (
Um das Hochziehen des Sektionaltores mechanisch zu unterstĂ¼tzen, ist an der Federwelle 7 eine Feder 10 vorgesehen, wobei Ă¼ber die Länge der Federwelle 7 verteilt auch mehrere Federn 10 vorgesehen werden können. Die Feder 10 ist als Torsionsfeder ausgebildet und in einem mittleren Bereich der Federwelle 7 angeordnet. Dabei ist ein Ende der Feder 10 an einem Halter 11 festgelegt, der an dem Paneel 12 fixiert ist. Das gegenĂ¼berliegende Ende der Feder 10 ist an einer Federbruchsicherung 13 fixiert, die an einem Halter 14 angeordnet ist. Die Federwelle 7 ist benachbart zu den Seiltrommeln 15 Ă¼ber Lager 9 an dem obersten Paneel 12 fixiert.In order to mechanically support the lifting of the sectional door, a
In den
An dem hervorstehenden Abschnitt 25 des Halters 14 ist eine DurchfĂ¼hrung 26 fĂ¼r die Federwelle 7 ausgebildet, so dass die Federwelle durch eine Ă–ffnung 27 und die DurchfĂ¼hrung 26 durchgefĂ¼hrt ist.A
Der Adapter 21 weist eine Ă–ffnung 28 auf, in der das Ritzel 16 eingefĂ¼gt ist. An gegenĂ¼berliegenden Seiten des Adapters 21 sind bogenförmige Langlöcher 22 ausgespart, in die ein Bolzen 33 zur verschwenkbaren Lagerung des Adapters 21 eingefĂ¼gt sind. Ein Ende der Feder 10 ist an dem Adapter 21 festgelegt, so dass dieser sich in einer Sperrposition befindet, in der der Sperrhebel 18 auĂŸer Eingriff von dem Ritzel 16 gehalten ist. Falls die Feder 10 bricht, wird keine Kraft mehr auf den Adapter 21 ausgeĂ¼bt, so dass dieser relativ zu dem Halter 14 verschwenken kann, so dass der Sperrhebel 18 durch die Kraft einer Spannfeder in Eingriff mit dem Ritzel 16 gelangt, so dass das Ritzel 16 gegen eine Drehung in eine erste Richtung gesperrt ist, aber in eine gegenĂ¼berliegenden zweite Richtung gedreht werden kann. Dadurch wird ein Herabfallen der Paneele 2 des Sektionaltores 1 vermieden, während in die gegenĂ¼berliegende Richtung ein Anheben der Paneele 2 durch Drehen der Federwelle 7 möglich ist. Der Sperrhebel 18 verrastet dann jeweils an den Zähnen 17 des Ritzels 16.The

Die Bolzen 33 sind hĂ¼lsenförmig ausgebildet und werden an dem Abschnitt 25 Ă¼ber Schrauben 23 fixiert. Dadurch kann der Adapter 21 Ă¼ber die bogenförmigen Langlöcher 22 entlang der Bolzen 33 verschwenkt werden.The
Der Sperrhebel 18 ist drehbar an dem Abschnitt 25 des Halters 14 gelagert, wobei hierfĂ¼r eine Ă–ffnung 34 in dem Sperrhebel 18 ausgebildet ist, in die HĂ¼lsen 20 und 31 eingefĂ¼gt sind, die von einer Schraube 30 durchgriffen werden, die in eine Ă–ffnung 32 des Abschnittes 25 eingefĂ¼gt ist. Der Sperrhebel 18 kann somit um die durch die HĂ¼lsen 20 und 31 gebildete Achse verschwenkt werden und wird Ă¼ber eine hier nicht dargestellte Feder zu dem Ritzel 16 vorgespannt. Ein Abschnitt des Sperrhebels 18 liegt in der entsperrten Position an dem Anschlag 29 des Adapters an, und bei einem Verschwenken des Adapters 21 wird der Sperrhebel 18 zu dem Ritzel hin verschwenkt, so dass die Sperrklinke 19 in Eingriff mit den Zähnen 17 gelangt.The locking
In dem dargestellten AusfĂ¼hrungsbeispiel ist nur eine Feder 10 entlang der Federwelle 7 angeordnet. Es ist auch möglich, mehrere Federn 10 entlang der Federwelle 7 zu positionieren, wobei dann an jeder Feder 10 eine Federbruchsicherung 13 gemĂ¤ĂŸ den
