• a protective barrier which has at least one carrier, but usually a plurality of spaced-apart carriers.
• the carriers may e.g. be arranged on a mountain slope to be built.
• a safety net is led.
• Each of the carriers is arranged on an associated base plate, with the help of which the carriers are fixed to the ground, using anchors and / or micropiles.
• At least one of the carriers is fixed to its associated bottom plate via a ball joint.
• the ball joint has for this purpose a pan and a guided in this ball, which is secured in position in the pan by means of a retaining device.
• the advantage is first achieved that the carrier relative to the bottom plate by pivoting the ball joint can be tilted and beyond also turned around its vertical axis against the bottom plate.
• This provides the advantage that the carrier can be optimally adapted to the conditions of the site with respect to their orientation.
• This provides the advantage of increasing the efficiency of the energy dissipation in articles impacting the safety net of the protective barrier according to the invention.
• a retaining device provides the advantage that it can be prevented that the ball is moved out of the pan when an object strikes the safety net and accordingly act forces on the carrier or carriers, which could cause such a moving out of the ball from the pan , According to the invention it is possible to attach the ball of the ball joint either on the carrier or the bottom plate and, accordingly, the pan either on the bottom plate or on the carrier.
• the bottom plate can be weight-optimized by the attachment of recesses in the bottom plate itself and / or the pan, if it is attached to the bottom plate.

"Support structure", which is usually formed by a plurality of beams 2 (also: supports), the anchor 53 and 54 in the ground or ground U of a slope H, as shown in FIG Depending on the length of the protective structure 1, a plurality of such carriers are provided, of which the carrier 2 is shown as being representative of all carriers in Fig. 1. If a plurality of carriers 2 are provided, these are selectable Spaced apart from each other on the slope H. Although it is also possible in principle that only such a support 2 is provided, but are usually, as I said, a plurality of mutually spaced carriers 2 are provided.
• the protective enclosure 1 further comprises a net or safety net 3, which is guided in the region of a support head 47 of the carrier 2 shown in FIG. 1 via a carrying cable arrangement 44, it being possible for the carrying cable arrangement 44 to comprise one or two upper carrying cables ,
• a lower suspension cable arrangement 46 is provided, which in turn may comprise one or two lower suspension cables.
• the center cable assembly 45 may include one or more center ropes, as in the example four center ropes.
• the middle cable arrangement 45 or its middle ropes can be guided on the support 2 via guide devices.
• the guide means may be formed here as a shackle, for example.
• the embodiment of the protective barrier 1 according to FIG. 1 illustrates that an upper guy rope or mountain-side retaining rope 49 is provided.
• the upper guy rope 49 holds the column head 47 of the carrier 2 via a fastening device 52 (rock anchor / ground anchor / anchor) in the underground U of the slope H.
• a brake element 51 is also provided in the guy rope 49.
• a bottom plate 4 is provided, on which the visible in Fig. 1 support 2 is mounted. If a plurality of such carrier 2 is provided, each carrier 2 is provided with an associated bottom plate 4 and fixed in the substrate U via this. According to the invention, the carrier 2 is fixed to its associated bottom plate 4 via a ball joint 5, which will be explained in detail below with reference to FIGS. 2 to 6.
• the ball joint 5 has a socket 6, which is fixed in the example case to the bottom plate 4, for example by welding.
• the ball joint 5 further comprises a ball 7, which is connected in the example case via a connecting piece 57 with the carrier 2, which is symbolized in Fig. 2 by its lower end plate.
• the ball 7 is further arranged in a ball receiving space 56 of the pan 6, so that the carrier 2, as shown in Fig. 2, can be pivoted about the center M of the ball 7, as well as about its vertical axis A can be rotated.
• the bottom plate of the carrier 2 is provided with two Abiaufbohrungen 58 and 59, which serve that in the carrier 2 penetrated liquid, if it is a hollow carrier, can run off. Furthermore, Figs. 2 and 3 illustrate that in the bottom plate 4 and in the pan 6, a recess 17 is arranged, which serves to save weight. As shown in FIG. 4, further edge-side recesses 60 and 61 are provided, which also serve to reduce the weight of the bottom plate 4.
• the protective structure 1 according to the invention is further provided with a retaining device 8, the construction of which results in particular from the representation of FIGS. 3, 5 and 6, to which reference is made below.
• the retaining device 8 has two L-shaped retaining fingers or retaining levers which are rotatably supported by pivot pins 11 and 14, respectively.
• the pivot pins 1 1, 14 for this purpose through recesses 25 and 28 and 29 in retaining plates 19, 20 and 21, 22 inserted therethrough and pass through a correspondingly aligned recess in the respective Holding fingers 9 and 10, so that this holding finger, as illustrated in Fig. 5, from an open position (retaining finger 9) in a holding position (retaining finger 10) can be pivoted.
• the holding plates 19 to 22 are each fixed to the bottom plate 4, preferably welded.
• guide surfaces 15 and 16 lie on the ball surface of the ball 7, wherein the guide surfaces 15 and 16 are adapted in their design to the respective spherical surface.
• the pan 6 has at its upper circumference in each case a recess for the engagement of the associated retaining fingers 9 and 10, wherein in these figures, only the recess 30 is visible, which is associated with the retaining finger 9.
• a corresponding opposite recess which is not visible due to the arrangement of the retaining finger 10 in the holding position, but is also provided.
• an arrangement of two trapezoidal plates 35 and 36 is further fixed to the Haiteplatte 4, preferably welded, each having through holes 37 and 38, which are aligned.
• These passage recesses 37 and 38 are provided on the outside of the retaining plate 4 in the region of the trapezoidal plates 36 and 37, ie outside the ground anchor 54, which has the advantage that guided through these fürgangsaus Principle 37 and 38 lower suspension cables do not come into contact with the carrier 2 can.
