COLLAPSIBLE SUPPORT FRAME FOR A HAMMOCK

Abstract

A collapsible support frame for a hammock (5) comprises a frame body (1) formed from a longitudinal member (2) and three struts at each of the two ends of the longitudinal member (2). Two of the struts serve as foot struts (3) and the third strut serves as a supporting arm (4) with an attachment point (15) for the hammock (5). The three struts at the two ends of the longitudinal member (2) and also the foot struts (3) at the opposite ends of the longitudinal member (2) are connected to one another, in each case, by tension means (12, 20) engaged at the strut ends. The struts can be folded out from an idle position, in which they are folded in against the longitudinal member (2), into a working position in which they are splayed out from the longitudinal member (2), and the attachment point (15) for the hammock (5) on the two supporting arms (4) is provided on one arm of a double-armed pivot lever (13), with the tension means (14) for the two foot struts (3) engaging on the other arm of said pivot lever.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The support frame according to the invention has a frame body 1 which comprises a longitudinal member 2 in the form of a hollow box girder and three struts hinged to each of the two ends of this box girder, namely two foot struts 3 and one strut as a supporting arm 4 for a hammock 5. These struts can be splayed out from an idle position folded in against the longitudinal member 2 and shown in FIG. 4 about hinge axes 6, 7 into a working position splayed away from the longitudinal member 2 as shown in FIG. 1 and can be folded back in the opposite direction into the idle position against the longitudinal member 2. The longitudinal member 2 is provided with receiving grooves 8, 9 for receiving the struts. As can be seen in particular from FIG. 2, the struts forming the supporting arms 4 are arranged offset from one another at the two ends of the longitudinal member 2 in the direction of their hinge axes 7 in order to be able to store them next to one another along the longitudinal member 2 on account of their length in the folded-in state, the minimum length of which thus corresponds to the length of the supporting arms 4. Since the foot struts 3 have a length smaller than half the length of the supporting arms 4, the foot struts 3 hinged at both ends of the longitudinal member 2 can be folded in pairs into a common receiving groove 8, as can be seen in FIG. 4.

[0016] Although the splayed working position of the struts is specified by stops 10, 11, essentially no load moments of the struts are to be transferred via these stops 10, 11. For this reason, the struts are each connected to a tension means 12 at the two ends of the longitudinal member 2, which is preferably guided in the form of an endless loop for tension compensation, although this is not mandatory. While the tension means 12 are merely deflected around the ends of the foot struts 3, they do not engage the supporting arms 4 directly but via double-armed pivot levers 13, which are mounted on the supporting arm ends so as to be freely rotatable about axes 14 parallel to the pivot axes 7. The pivot levers 13 form, with their lever arm opposite the lever arm for the tension means 14, an attachment point 15 for the hammock 5, which can be suspended with the aid of a tension means loop 16 in a hook opening forming the attachment point 15, as can be seen in particular from FIG. 3. Since the pivot lever 13 forms two suspension hooks 18 for the hammock 5, in contrast to only one suspension hook 17 for receiving the tension means 12 connecting the three strut ends, the respective sag of the hammock 5 in the unloaded state can be adjusted by the selection of the respective suspension hook 18. In the loaded state, the pivot levers 13 result in a load compensation which ensures a largely moment-free loading of the struts. To make it easier to hook the tension means 12 or the tension means loop 16 into the hooks 17, 18, the pivot lever 13 can be formed with a handle attachment 19.

[0017] However, the foot struts 3 on each end of the longitudinal member 2 must not only be connected to each other and to the supporting arm 4 by the tension means 12, but must also be braced relative to the foot struts 3 at the opposite ends of the longitudinal member 2. For this purpose, a preferably also endlessly guided tension means 20 is provided, whose sections between the two ends of the longitudinal member 2 are either guided in parallel or extend in a crossed manner.

[0018] The longitudinal member 2, which is designed as a hollow box girder, can advantageously be used as a storage space, in particular for the hammock 5 and the tension means 12, 20. For this purpose, a tubular piece 21 forming the storage space can be provided inside the box girder, which is closed at the end by an openable lid 22. A lid 22 in the form of a flap is indicated by a dashed dot in FIG. 4 in a partially open position.
