    专利说明:

    The invention relates to a boom, in particular for a commercial vehicle, - wherein a spar is rotatably connected to a fastening device for a vehicle about a rear fixed axis, - wherein a tool lever is rotatably connected to the spar about a front fixed axis, - wherein a'Umlenkdreieck to a central fixed axis is rotatably connected to the spar, - wherein a rear strut about a first strut pivot axis rotatably connected to the attachment device and about a second strut pivot axis rotatably connected to the Umlenkdreieck - and wherein a front strut about a third strut pivot axis rotatable with the Umlenkdreieck and a fourth strut pivot axis is rotatably connected to the tool lever.
    Such usually designed as a parallel link boom are known for example from EP 1 903 147 A. In general, two such boom side by side and connected to each other mounted on a vehicle and move a fixed to the jib tool. In addition to the most accurate control there are other efforts to improve such boom. On the one hand, the field of view of an operator should be as little as possible restricted, on the other hand, the boom should be able to operate as safely as possible. Both can be accomplished by concealing as many elements of the boom as possible under a fairing. So can be reduced to wear leading pollution of the moving parts of the boom.
    In addition, many moving parts, which otherwise pose a potential risk of injury, are no longer easily accessible. However, in a conventional arrangement of the elements of a parallel link, the fairing takes a great deal
    Part of the field of view of an operator, which on the one hand greatly restricts the ease of use and on the other creates a new security risk, since the operator can no longer overlook their environment.
    A solution to make the boom slimmer, and thus to make the field of view of the operator more free, provides the EP 1 903 147 A. Here, a strut of the cantilever is bent so that the central region of the strut to a large extent further into the spar is put into it. However, this has the disadvantage that the strut, which has created by this form kinks or a curvature, loses stability. This must be compensated by a more massive design of the strut, which makes both the production more expensive, as caused by a higher weight and a higher weight.
    The invention is therefore based on the object to overcome the disadvantages described above and to provide a space-saving, while robust and economical way for boom of the type mentioned.
    This object is achieved according to the invention by a boom of the type mentioned, which is characterized in that - the rear and the central fixed axis span a first plane that the rear strut intersects the first plane, - that the middle and the front fixed axis a second Expand the plane and that the front strut intersects the second plane.
    This non-parallel, but "crosswise" arrangement can save a lot of space, with less bending of the rear strut, and at the same time acting as a fairing and support for the fixed axles This saves space and at the same time eliminates the need for a parallel arrangement In a preferred embodiment, therefore, the struts are disposed substantially within the spar.
    In a preferred embodiment of the invention, the front strut on a tool drive, by which the length of the strut is variable to move the tool lever. Of course, embodiments without a tool drive are conceivable. In this case, the tool is moved as known by the parallel core. In a further preferred embodiment of the invention, a tool link which can be connected to a tool is arranged for moving on the tool lever.
    In order to make the tool lever and the associated tool guide easily accessible, in a further preferred embodiment, the tool lever is arranged substantially half outside and half inside the spar.
    In the prior art, the deflection triangle is arranged in the region of the bend and aligned with the (central) fixed axis to the outside of the bend in cantilevers, which have a kink. In a particularly preferred embodiment of the invention, the crossing is brought about in that the deflection triangle is arranged inversely. Accordingly, in a particularly preferred embodiment of the invention the spar has a kink, the middle fixed axis of the deflection triangle is arranged in the region of the inside of the kink and the second and third strut pivot axis are arranged therefrom.
    Further preferred embodiments of the invention are the subject of the remaining dependent claims.
    Hereinafter, a preferred embodiment of the invention will be described with reference to the drawings. It shows:
    Fig. 1 shows a section through a boom 1 with a tool 2 and
    Fig. 2 shows the boom with the invention schematically representing connecting lines and longitudinal axes.
    The boom 1 shown in Fig. 1 with a tool 2 has a spar 3, which serves both as a carrier for different elements of the boom and as a lining of the boom. The spar 3 is rotatably connected to a fixing device 5 about a rear fixed axis 4. With the fastening device 5, the boom 1 can be attached to a vehicle. Of course, embodiments are also conceivable in which the fastening device 5 is an integral part of the commercial vehicle. At the other end of the spar 3, a tool lever 6 is rotatably connected to the spar 3 about a front fixed axis 7. In a central region of the spar 3, a deflection triangle 8 is arranged. The deflection triangle 8 is rotatably connected to the spar 3 about a central fixed axis 9. A rear strut 11 is rotatably connected to the fastening device 5 about a first strut pivot axis 12 and rotatably connected to the deflection triangle 8 about a second strut pivot axis 13. A front strut 14 is rotatably connected to the deflection triangle 8 about a third strut pivot axis 15 and rotatably connected to the tool lever 6 about a fourth strut pivot axis 16. In the illustrated embodiment, the front strut 14 has a tool drive 17, via which the length of the front strut 14 can be changed. Thus, the position of the tool 2 can be changed via the tool lever 6.
    In the illustrated embodiment, a tool link 18 for this purpose is rotatably connected to the tool lever 6 about a handlebar pivot axis 19. In order to move the spar 3 relative to the vehicle or the fastening device 5, a lifting drive 21 is provided.
    It can be seen that the rear fixed axis 4 in the illustrated
    Orientation of the boom 1 above the first
    Strut pivot axis 12 and the middle fixed axis 9 below the second strut pivot axis 13 is located. This results from the fact that the deflection triangle 8 is arranged inversely in the spar 3 in contrast to the prior art. Although the deflection triangle 8 is, as is common in the prior art, in the region of a bend 22 of the spar 3. However, the central fixed axis of the deflection triangle 8 in the region of an inner side of the bend 22 is arranged.
    The basic, according to the invention, crosswise arrangement of
    Struts with respect to the fixed axes is illustrated in more detail in FIG. 2 o. Of the rear and front strut 11, 14 each symbolized by dotted lines 23, 24 longitudinal axes of the struts 11, 14 are shown. Furthermore, dot-dashed connecting lines 25, 26 between the fixed axes 4, 7, 9 located. This shows a rear dash-dotted
    Connecting line 25 symbolically a spanned by the rear fixed axis 4 and the central fixed axis 9 first level. A front dash-dotted line 26 symbolically shows a spanned by the middle fixed axis 9 and the front fixed axis 7 second plane.
    It can be seen that the rear strut 11 represented by the rear dotted line 23 intersects the first plane, and that the front strut 14, symbolically represented by the front dotted line 24, intersects the second plane.
