BACKGROUND OF THE INVENTION 
     The invention relates to a hinge, preferably for furniture, comprising a hinge arm or a fixed-body hinge section and a pivotable hinge section flexibly connected thereto, whose movement to the closed position is at least damped over part of the closure path by a rotation damper. 
     Hinges of this type are known, for example, from DE 201 04 100 U1. In these known hinges, conventional rotation dampers are used wherein the rotation body damped by a damping fluid is located in a cylindrical housing and on at least one axial pin of the rotation body supported in the covers of the housing there is fixedly positioned a pinion which meshes with a toothed segment of one of the pivotable hinge sections. This known hinge can only be produced with relatively high manufacturing costs because a pinion-toothed segment arrangement is required to transmit the damping force. 
     SUMMARY OF THE INVENTION 
     The object of the invention is thus to provide a hinge of the type specified initially which can be manufactured with a reduced expenditure. 
     This object is solved according to the invention by the rotation damper being an axial damper whose axis forms a hinge axis of the hinge and whose cylinder is fixedly connected to the hinge section pivotably supported on the axis. 
     The damping device of this known hinge can be manufactured with very much lower expenditure because the axis of the axial damper forms a hinge axis of the hinge and the cylinder of the axial damper is fixedly connected to the pivotable hinge section so that the axial damper is integrated in a hinge axis of the hinge and special gearing means to transmit the damping force from the rotation damper to the pivotable hinge section are dispensed with. 
     Rotation dampers in the form of axial dampers suitable for incorporation in the hinge according to the invention are inherently known and are manufactured and distributed in various embodiments. Thus, a detailed description of the design of such known axial dampers is dispensed with here. 
     Double guide hinges can be damped particularly advantageously by axial dampers in the fashion according to the invention by the axis of the axial damper forming the joint pin of one of the four hinges and the end of the guide supported thereon being fixedly connected to the cylinder. 
     In a further development of the invention it is provided that one of the fixed joint pins is formed by the axis of the axial damper and the axis is thereby specified by the legs of a U-shaped hinge arm such that one end of the axis projecting beyond the cylinder has a non-circular or polygonal, e.g. square cross-section and engages in a complementary recess of one leg of the hinge arm and the other end bears a circular disk whose diameter is as large as the diameter of the cylinder which is held in a complementary hole of the other leg. In this embodiment the axial damper can be assembled in a simple fashion by sliding it through the hole until the non-circular or polygonal axial pin is inserted in the complementary recess of one leg and the circular disk is inserted in the corresponding complementary hole of the other legs. In this fashion the axis of the axial damper is held non-rotatably on the hinge arm. 
     According to a preferred embodiment it is provided that one of the pivotable joint pins is formed by the axis of the axial damper and an axial pin is held in a wall of the pivotable hinge section, that the cylinder is connected non-rotatably to an outer end of the guide and the other axial pin is provided with a radial extension with a hole in which the pivotable bolt of the other guide engages. Since the axis of the axial damper is held non-rotatably by the radial extension, the axial pin located at the front during insertion into the pivotable hinge section can be cylindrical. 
     In order that the axial damper can be inserted simply from one side between the walls of the pivotable hinge section supporting it, it is provided in a further development of the invention that the wall of the pivotable hinge section which lies opposite the wall holding the axial pin, is provided with a hole in which the end region of the cylinder of the axial damper is pivoted with clearance. 
     In order to fix the pushed-through axial pin of the axial damper in its recess or hole, this can be provided with a rivet head. 
     The pivotable hinge section or one end of a guide can easily be fixed to the cylinder of the axial damper by providing the cylinder with at least one flattened area for its fixing between the legs of a U-shaped guide or to a pivotable hinge section and providing the legs or the pivotable hinge section with a corresponding complementary recess.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The double guide hinges from  FIGS. 1 and 5  comprise conventional double guide hinges which, however, have the feature that they are fitted with a rotation damper in the form of an axial damper to damp the closure movement of doors or flaps. 
     The double guide hinges shown in the drawings consist of a U-shaped hinge arm  1  made of Zamak or a stamped metal part, which is affixed to a cupboard wall or a body section  2  in a usual fashion. Supported between the legs of the hinge arm  1  are the ends of guides  3 ,  4  of which the guide  3  at both its ends and the guide  4  at its rear end are provided with U-shaped, inclined bearing lugs which are provided with holes. At its outer end the guide  3  is provided with a rolled-up eye  5  which is supported on a bolt  7  held in the hinge cup  6 . On the bearing bolt  8  which is held between the legs of the hinge arm  1  and on which the inner end of the outer guide  3  is supported, there is mounted a double hairpin-shaped curved leaf spring  9  which is supported with its one leg on the web section of the hinge arm  1  and with its other leg on a control curve constructed at the inner end of the inner guide  4 . The outer end of the outer guide  3  is supported on a bolt  10  held in the hinge cup  6 . The hinge cup  6  is fixed as shown in a blind hole of a door or flap  11 . In this respect the double guide hinges shown in the drawing are of known design so that a more detailed description can be dispensed with. 
     In the exemplary embodiment from  FIGS. 1 to 3  the inner end of the inner guide  4  is supported via the lugs  12  bent from it in a U-shaped fashion on an axial damper  13 , which is shown in detail in  FIG. 6  and whose axial pins  15 ,  16  which project beyond the cylinder  14  at both ends, are held in the legs of the hinge arm  1 . The leg  17  of the hinge arm  1  located at the back in  FIG. 1  is provided with a square opening in which the square axial pin  15  of the axial damper  13  matched thereto and inserted therein is held non-rotatably. Adjacent to the square axial pin  15  the axis  18  of the axial damper  13  is provided with an annular step  19  via which the axis  18  is supported on the edge of the square opening in the rear leg  17  of the hinge arm  1 . The cylinder  14  of the axial damper  13  is provided with flattened areas  20  on the opposite sides. The lugs  12  of the inner guide  4  are provided with openings corresponding to the profile of the cylinder  14  so that the axial damper  13  can be slid through these openings such that the inner guide  4  is connected non-rotatably to the cylinder  14 . In order to allow the axial damper  13  to be slid through the lugs  12 , on the right axial pin of the axial damper  13  which can be seen from  FIG. 6  there is placed a circular disk  16  which is held in a complementary hole  22  of the front leg  23  of the hinge arm  1 . The diameter of the disk  16  corresponds to the diameter of the cylinder  14  or is slightly larger than this. In order to fix the axis  18  of the axial damper  13  the end of the square axial pin  15  which passes through the square opening in the leg  17  is provided with a rivet head  24 . 
     In the exemplary embodiment from  FIG. 4  the inner end of the outer guide  3  is supported between the legs of the hinge arm  1  on an axial damper  13  in the fashion described with reference to  FIGS. 1 to 3  and  6 . Since in the exemplary embodiment from  FIG. 4  the closing spring cannot be held on the axis formed by the axial damper, between the legs of the hinge arm  1  there can be arranged an additional bolt  25  on which a spring clip  26  can be mounted. 
     In the exemplary embodiment from  FIG. 5  the outer end of the outer guide  3  is supported between the walls  29 ,  30  of the hinge cup  6  on an axis which is formed by the axial damper  28  which can be seen from  FIG. 7 . The cylinder  14  of the rotation damper  28  is held non-rotatably in the fashion described in openings of the lugs bent in a U shape from the web section of the guide  3 . The right axial pin of the axial damper  28  which can be seen from  FIG. 7  is provided with a radial extension  32  which is provided with a hole  33  into which engages one end of the bearing bolt  34  on which the rolled-up eye  5  of the inner guide  4  is supported on the hinge cup  6 . Since the axis  18  of the axial damper  28  is held non-rotatably by the radial extension  32 , the other axial pin  34  of the axial damper  28  can be constructed as round and inserted in a hole in the wall  30  of the hinge cup  6 . The axial pin  34  is again provided with a rivet head  35  to hold it. 
     In order that the axial damper  28  can be slid from the slide-in side formed by the wall  29  of the hinge cup  6  between the walls of the hinge cup  6  and the lugs of the outer guide  3 , the wall  29  situated opposite the wall  30  of the hinge cup  6  which holds the axial pin  34 , is provided with a hole in which a cylindrical disk-shaped section  34  is held, which is connected non-rotatably to the axis  18 , is constructed integrally with the extension  32  and whose diameter is at least as large as the diameter of the cylinder  14 .

Summary:
The movement of a hinge, preferably for furniture, comprising a hinge arm or a fixed-body hinge section and a pivotable hinge section flexibly connected thereto, is damped by a rotation damper at least damped over part of the closure path to the closed position. In order that the hinge can be manufactured at reduced cost, the rotation damper is an axial damper whose axis forms a hinge axis of the hinge and whose cylinder is fixedly connected to the hinge section which is pivotably supported on the axis.
