Description

The invention relates to a vehicle body with a frame and at least one pendulum swingable about a longitudinal axis, which is divided along a first vertical axis and two pivotable about a second and third vertical axis doors which are interconnected and exclusively locked to each other and the closed, pendulable side wall form, wherein the locking of the doors takes place in the areas of the upper end and the lower end of the side wall.

Such a vehicle body is, for example, of the generic type US 2,806,735 A known. The locking of the doors to each other, so that the pendulum tailgate is adjustable, is very expensive. They must be closed by means of a bolt provided at the top and bottom of the door, which must be mechanically operated. Depending on the height of the vehicle body and depending on the height of the operator, the upper bar can not operate without further aids.

The DE 25 27 033 A1 discloses an upper closure device for around the upper and / or lower axis hinged and swinging side walls of commercial vehicles, which can be installed in the interior of the rounds. For this purpose, a control lever is provided, which ends in a cam, which is arranged in a housing open at least on one side. Through the housing a push rod is guided, the end of which is supported by a coil spring against the housing. In the push rod, the cam is mounted and adjustably connected to the upper end of the push rod with a first latch member. On the side wall, a pin is fixed in the longitudinal direction, which is designed as a second locking member and with the other locking member in the locking position, the pin comprises two sides.

A two-axle three-way tipper of a similar construction is marketed, for example, by Brantner under the name "Z 18051 MULTIPLEX". The doors are pivotally mounted on the front and rear side wall. In order to allow the swinging of each door about a longitudinal axis, the upper hinges are gimbaled. The doors are hinged to oscillate or to close the side wall to a vertical central rungs, which is attached to the frame. To facilitate the loading of the trailer, the middle stanchion can be removed when the doors are swung open. To swing the side wall, the stanchion must remain installed as it forms the upper bearing for both swinging doors. The disadvantage of this is that bulk material can get stuck when tilting the vehicle body to the middle rung, which makes it difficult to empty the trailer and requires manual intervention.

The US 2004/0 160 079 A1 discloses the tailgate of a pickup car form multiple parts and to store two doors pivotally mounted in a U-shaped frame that can be swung down together with the doors to release the cargo area.

In the DE 24 29 395 A1 It is proposed that in road trucks with a tiltable structure, the rear side wall with two leaves form each pivotable about a vertical axis, and can be opened individually.

On this basis, the locking of the doors to each other should be simplified and in particular the use of tools for locking the two doors are avoided together.

To solve the problem, a generic vehicle body is characterized in that for locking a central locking mechanism is provided, which consists of an upper, wedge-shaped latch and a lower pin-shaped latch, and the upper latch and the lower latch are connected to each other via a rod.

Form by the exclusively interconnected and interlocked doors the closed, pendulum tailgate can account for the middle Runge. The stability of the closed side wall is achieved only by the lock. In addition, only two upper cardan joints are necessary, which reduces the manufacturing and maintenance costs.

A secure locking of the doors to each other takes place only in the areas of the upper and lower ends of the hull, wherein for locking a central locking mechanism is provided, which consists of an upper wedge-shaped latch and a lower pin formed as a bolt, and the upper latch and the lower Latches are connected to each other via a rod.

When the upper latch is slidably mounted on the rod in an axial direction against the force of a spring, the latch is securely held in its upper locking position. The spring is preferably a compression spring. Also, shocks due to road bumps while driving, transmitted through the side walls of the locking mechanism, can not cause the bolt dissolves, as he, if he wandered down due to the vibration should, by the spring force is pushed back immediately.

The axial displacement of the upper bolt relative to the rod is preferably limited by a stop provided on the rod.

Preferably, the rod via a pivotally mounted on one of the doors lever in the axial direction (vertical direction) is slidably disposed.

If the lever has a handle which is pivotable about a perpendicular to the pivot axis of the lever at a distance to this extending second pivot axis, it is possible to fold the handle on the side wall, so that it does not protrude laterally while driving and thus limits the working area , The rod is preferably arranged in a housing provided on one of the doors and substantially closed, wherein only parts of the upper bolt and the lower bolt protrude from the housing in the axial direction.

If the upper bar cooperates with a substantially rectangular, in particular square trained eyelet on the other door in the cross section, the door is drawn by the wedge shape of the bolt in the upper region, ie in the region of the pendulum axis to the other door and rigidly closed with this. In the lower area, in which the forces acting on the side wall forces are lower, there is a secure locking by the pin, at the same time a centering of the two closed doors is achieved.

With the aid of a drawing, an embodiment of the invention will be described in more detail below.

The vehicle body, which can be mounted on the chassis of a trailer or a truck, consists essentially of the surrounding frame 1 , the crossbar 2 and side members 3 stiffened is formed and the side walls 4 . 5 . 6 . 7 , At least in the longitudinal direction L running long side wall 4 is along a first vertical axis H ₁ divided and forms two doors 4a . 4b off, around a second or third vertical axis H ₂ . H ₃ are arranged pivotally. Accordingly, the ship's side 6 be educated. The ship's side 4 and possibly also the ship's side 6 is about a longitudinal axis L (Pendulum axle) also oscillating stored when the two doors 4a . 4b closed and locked to each other. To the pendulum movement of the side wall 4 and the pivoting movement of the doors 4a . 4b to enable are the upper joints 8th gimbal trained (cf. 7 ).

The doors 4a . 4b are made of rotating profiles 4 ^I . 4 ^II . 4 ^III . 4 ^IV formed and with vertical and horizontal struts 4 ^V . 4 ^VI strengthened.

So that the side wall 4 can oscillate and has sufficient rigidity without having a conventional center post on the frame 1 is arranged at the two doors 4a . 4b could be struck, the doors have to 4a . 4b firmly and be locked rigidly together. This is a locking mechanism 10 provided that from a pole 11 and an upper latch attached thereto 12 and a lower bar 13 stands, with the bars 12 . 13 with eyelets 22 . 23 interact. The bars 12 . 13 the locking mechanism 10 are in one of the doors 4b and the eyelets 22 . 23 in the other door 4a arranged. The upper bar 12 is with the top of the pole 11 screwed. The pole 11 is with a bolt 14 transverse to the axial direction A running provided on the one as a stop 15 Serving disc rests. At the bottom of the bolt 12 is a tab 19 arranged with a bore not designated. With the tab 19 is the cross-sectionally square bar 12 on the pole 11 placed. Between the tab 19 and the stop 15 is a compression spring 16 arranged. The upper end of the bolt 12 is wedge-shaped, with the bevelled surface toward the center of the door 4b has. In the upper profile 4 ^I the door 4a is an eyelet 22 arranged with a square cross-section recess. At the bottom of the profile 4 ^IV is a stop 24 arranged on which a pin-shaped eyelet 23 is provided, which is provided with a through hole whose diameter is slightly larger than the diameter of the pin-shaped lower bolt 13 ,

The bolt 13 can against the force of the compression spring 16 to be moved. A maximum way is however by the stop 15 limited. The compression spring has the task of the wedge-shaped latch 12 always keep in its upper position and prevent it from jarring from its locking and the two doors 4a . 4b can release under tension to each other holding position.

At the bottom of the pole 11 is a tab 17 with a long hole 18 appropriate. Parallel to the pole 11 running is the lower, pin-shaped latch 13 in the flap 17 attached.

The locking mechanism 10 is in profile 4 ^VI in the axial direction A slidably mounted and is of a housing 4 ^VII covered, from the only tab 17 and the wedge-shaped top of the bolt 12 stand out (compare 12 ). For locking the doors 4a . 4b is a lever 30 provided, which is about a first pivot axis S ₁ in the lower profile 4 ^III the door 4b is pivotally mounted and a pin 31 has, in the slot 18 the tab 17 slides.

At the the pin 31 opposite end of the lever 30 is a jack 32 provided in which a handle 33 about a second pivot axis S ₂ hinged is stored.

For closing and locking the doors 4a . 4b these will be around the Hochachsen H ₂ . H ₃ swiveled, until the at the door 4a provided stop 24 to the housing 4 ^VII strikes. The upper bar 12 and the lower bar 13 In this situation, they are aligned with the upper eyelet 22 or the lower eyelet 23 , The handle 33 gets off the lever 30 folded. As 16 clearly shows is by a pivotal movement of the lever 30 in the clockwise direction the ship's side 4 locked. By the pivoting movement of the lever 30 around the pivot axis S ₁ becomes the pin 31 on a circular path upwards and in the slot 18 the tab 7 shifted to the right on the drawing, causing the tab 17 or the rod 11 in the axial direction A is moved upwards. The wedge-shaped top of the top bolt 12 grabs the eyelet 22 and pulls in a further upward movement of the rod 11 the door 4a in the direction of the door 4b and the pin of the lower bolt 13 dives into the hole of the lower eyelet 23 one. Will the lever 30 pivoted counterclockwise, the pin slides 31 in the slot 18 to the left and pulls the tab 17 down, leaving the locking mechanism 10 is unlocked. For reasons of operational safety, the lower portion of the locking mechanism 10 or the lower bar 13 with a cap 34 covered. To center in the eyelet 23 To simplify, the pen can 13 be pointed.

If the two doors 4a . 4b closed and locked together, the side wall can 4 around the longitudinal axis L commute. For the lower locking of the side wall 4 at the frame 1 are at the doors 4a . 4b tabs 40 arranged in the gripper 50 can be swung on one over a lever 52 swiveling in the frame 1 arranged wave 51 are attached.
