    The invention relates to a collapsible support frame for a hammock with a frame body made of straight struts symmetrical to a longitudinal center plane and the struts connecting the struts together, which form plug-in receptacles for the struts.
    In order to obtain a simple collapsible support frame for a hammock, it is known (DE 343 872) to assemble the frame body from two substantially U-shaped frame parts which are symmetrical about a longitudinal center plane and which are connected to one another at their free ends to accommodate the hammock and each for are composed of straight struts. A disadvantage of these known frame bodies is that the struts and the plug connections receiving the struts between the struts of the frame parts are subjected to bending, which necessitates comparatively heavy structures, which contradicts the requirement for a lightweight support frame.
    So that the support frame can be adapted to different support lengths for the hammock, it is also known (DE 24 47 696 A) to assemble the frame body from two frame parts, each of which comprises three struts, which are connected to one another by a knot, spanning a tetrahedron two are designed as foot struts and the third strut running in the plane of symmetry between the two foot struts as a support arm for the hammock. The two frame parts are connected by a longitudinal strut acting on the node pieces, which are composed of two partial struts which are adjustable in relation to one another in order to be able to set different support lengths for the hammock. This one too

    Construction, the node pieces must support the weight and torque loads of the struts, so that welded connections between the struts and the node pieces must be provided.
    The invention is therefore based on the object of designing a collapsible support frame for a hammock in such a way that, despite a light construction, the weight and torque loads that occur can be safely absorbed without impairing the handling of the frame body during assembly or disassembly.
    Starting from a support frame of the type described at the outset, the invention achieves the object in that the frame body comprises two node pieces with plug receptacles for three struts spanning a tetrahedron, two of which act as foot struts and the third strut running in the plane of symmetry between the two foot struts as Support arm for the hammock are designed so that between the two knot pieces on the side facing away from the tetrahedron a longitudinal strut engaging in aligned plug-in receptacles of the knot pieces is provided and that both the struts forming a tetrahedron and the foot struts of the opposing knot pieces are connected to one another by the strut ends attacking traction devices are connected.
    Due to the additional mutual tensioning of the struts starting from a node piece, spanning a tetrahedron with each other and the foot struts of the opposing tetrahedra, the struts are essentially stressed so that the node pieces remain largely free of bending moment loads. This means that the main task of the plug-in receptacles is to form an abutment for pressure support for the struts attacking the node pieces. Since a one-sided clamping of the struts in the plug-in receptacles in the sense of a flexible support is thus eliminated, advantageous conditions are created for plug connections that are not to be secured, because the struts are caused by the tensioning means
    3/11 held in the mating engagement and loaded in the direction of the mating engagement when the hammock is used. Because of the struts used in the sense of pressure rods, these can be made comparatively easily, which benefits the handling of the frame body during assembly and folding, especially since a high degree of accuracy is not required. The additional traction means does not pose any difficulties because the traction means only have to be hooked into connections prepared on the struts.
    So that the height of the hammock support can be kept low despite the longitudinal strut running underneath the hammock, it is advisable to choose the length of the support arms for the hammock at least twice the length of the foot struts. If the longitudinal strut between the two node pieces is formed from two partial struts which can be plugged together, the space required for the folded support frame is reduced, which is then determined not by the longitudinal strut but by the length of the support arms.
    The subject matter of the invention is shown in the drawing, for example. Show it
    1 is a side view of a collapsible support frame for a hammock,
    Fig. 2, this support frame in a front view on a larger scale and
    Fig. 3 shows the support frame in an axonometric diagram.
    The support frame shown has a frame body 1 with two ones
    Knot pieces 2, 3 defining the longitudinal axis of the frame, which are connected to one another by a longitudinal strut 4. For this purpose, the longitudinal strut 4, which can preferably be composed of two partial struts 5, 6, engages in one plug receptacle 7 of the node pieces 2, 3. The node pieces 2, 3 are also provided with plug-in receptacles 8, 9 for three struts, namely two foot struts 10 and a support arm 11, which span a tetrahedron. As nodes 2, 3
    4/11 are preferably spherical bodies which are provided with radial openings for the plug receptacles 7, 8 and 9.
    The support arms 11 for the hammock 12 lie in the plane of symmetry forming a longitudinal center plane of the frame body 1 between the foot struts 10. which run along the rest of the tetrahedron edges, so that the traction means 13 which are respectively suspended between the ends of the foot struts 10 and the support arm 11 prevent the tetrahedra spanned by the foot struts 10 and the support arm 11 from spreading apart. In addition, the foot struts 10 of the opposite node pieces 2, 3 are mutually connected by traction means 14, as can be seen in particular in FIG. 3. The traction means 14 connecting the foot struts 10 of the mutually opposite node pieces 2, 3 can also run crosswise, because it is only the task of these traction means 14 to avoid spreading the foot struts 10 in the direction of the longitudinal axis of the frame.
    Due to the mutual bracing of the foot struts 10 and the support arm 11, the loads which otherwise lead to bending stress on the support arm 11 clamped on one side are absorbed and removed by the traction means 13 by a hammock user, so that the support arm 11, but also the foot struts 10, essentially only as compression rods be used, which is an advantageous requirement for a simple, easy-to-use construction. To fold the frame body 1, first only the traction means 13, 14 need to be removed before the struts are pulled out of the plug-in receptacles 7, 8 and 9 of the node pieces 2, 3 and the longitudinal strut 4 is broken down into the partial struts 5, 6. The dismantled frame body 1 is assembled in the reverse order.
