DETAILED DESCRIPTION OF THE FIGURES

[0049] The mobile stop device 1 shown in FIG. 1 has a weight base 10 and an anchor element 20. The anchor element 20 comprises a central mast 21, on which a stop point 23 for a safety device, in particular for a rope, is formed. At the other end, the anchor element 20 has connecting means 22, by means of which the anchor element 20 is detachably connected to the weight base 10.

[0050] The weight base 10 has a base body 100 with four arms 110 as extension arms. The arms 110 are each designed in a tubular shape for the reception of weights 120 in their end sections, that is, at their free ends. The weights 120 are integrated into the arms 110 in the area of the end sections. This results in an eccentric arrangement of the weights 120 and, consequently, in a particularly favorable mass distribution.

[0051] The base body 100 is mounted on bearing bodies 130 made of an elastomer material that has an anti-slip effect. The bearing bodies 130 are each arranged under the arms 110 at their free ends, so that the load of the weights 120 rests on the bearing bodies 130. The upper sides of the arms 110 have recesses which, together with recesses in the weights 120, form crane lugs 114. The weight base 10 or the mobile stop device 1 can be connected to a 4-strand crane sling in the area of the crane lugs 114. On the upper side, the arms 110 also form lugs 112 that serve as stacking aids. When weight bases 10 are stacked on top of each other, the lugs 112 of the lower weight base 10 engage in corresponding recesses 113 of the weight base 10 located above. This prevents the weight bases 10 from moving relative to one another.

[0052] The arms 110 of the weight base 10 shown in FIG. 1 converge in a central part 150 which has receptions 151 for the connecting means 22 of the anchor element 20 for the releasable connection to the base body 100. The connecting means 22 are in the form of claws which, for the releasable connection to the base body 100, are inserted into the receptions 151 of the center part 150 and are brought into latching engagement with the base body 100 (see FIGS. 2, 10 and 11). The center section 150 also forms four clamping belt receptacles 152, which are each arranged laterally on the center section 150 between two arms 110.

[0053] The weights 120 received in the arms 110 are plate-shaped, wherein a plurality of plate-shaped weights 120 each form a plate pack received in an arm 110. The individual plate-shaped weights 120 are arranged in an upright position. The weights 120 can thus be inserted individually or as a plate pack into the tubular end sections of the arms 110. Insertion preferably takes place from the inside outwards, sinceas can be seen in particular from FIGS. 3 and 4the arms 110 have undersides 111 that run at an angle towards the end or form surfaces 116 that run at an angle. In the present case, the sloping surfaces 116 are formed by angled base plates 115. Each base plate 115 also forms a stop 122 for the plate-shaped weights 120, so that the end position of the weights 120 is predetermined by the stop 122. This facilitates the insertion of bolts 121, by means of which the weights 120 are fixed in the arms 110. Since the weights 120 are held upright in the arms 110, the screw bolts 121 can be arranged transversely in this respect, so that their heads and nuts screwed on at the other end come to rest on the side of the arms 110 in each case.

[0054] The bearing bodies 130 are also arranged in the area of the angled base plates 115. As can be seen in particular from FIG. 5, a plurality of bearing bodies 130 are arranged on the underside 111 of each arm 110. These are each elongated and arranged at an angle to one another. In the area of the inclined surface 116, each arm 110 has three bearing bodies 130. A first bearing body 130 is arranged in each case in the center under the arm 110 and oriented in the longitudinal direction of the arm 110. The central bearing body 130 is flanked by two further bearing bodies 130, which are each arranged at the same angular distance a from the first bearing body 130. The angular distance measured between the longitudinal axes of the bearing bodies 130is 45 in the present case. The three bearing bodies 130 each have a contact surface 131 that is convex in the longitudinal direction of the bearing bodies 130 (see in particular FIGS. 3 and 4). Outside the oblique surface 116, a further bearing body 130 is attached to the floor panel 115, which is aligned transversely to the longitudinal direction of the arm 110 and has a flat contact surface 131 (see in particular FIGS. 3 and 4).

[0055] In the event of a crash, a tensile force F acts on the attachment point 23, causing a tilting moment such that the weight base 10 performs a tilting movement (see FIG. 6). The weight base 10 then rolls over at least one bearing body 130 with a convex contact surface 131. When the ground is damp or wet, this rolling motion causes a displacement effect that prevents the formation of a friction-reducing film of moisture between the bearing body 130 and the ground. This reduces the risk of the weight base 10 slipping on a film of moisture towards the fall edge. The arrangement of the bearing bodies 130 in the area of the sloping surfaces 116 further increases the displacement effect.

[0056] Provided that the weight base 10 does not tilt, it essentially rests on the four bearing bodies 130, whose contact surfaces 131 are flat.

[0057] FIGS. 7 to 9 show the anchor element 20 and its connecting means 22, via which the anchor element 20 is detachably connected to the base body 100. The connecting means 22, which are designed as claws, are inserted into the receptions 151 of the center part 150 and are brought into latching engagement with the base body 100. In this respect, at least one claw is designed to be movable, in particular to be pivotable.

[0058] The undersides 111 of the arms 110 are designed in a stepped manner so that the distance of the base body 100 from the ground is greater further inwards than in the area of the end sections of the arms 110 that receive the weights 120. This free space can be used for the reception of a lifting device 2, as shown in FIG. 10 by way of example. The lifting device 2 can be used to easily move the weight base 10 or the mobile stop device 1.

[0059] The low height of the weight base 10 shown contributes to a low center of gravity, which increases the stability of the weight base 10. However, if the weight base 10 or the mobile stop device 1 is to be used on a thin concrete layer of a prefabricated ceiling 3 with reinforcement 4 (see FIG. 14), the low height of the weight base 10 can be a disadvantage. To remedy this, the weight base 10 can be combined with spacer elements 140, which are attached to the underside 111 of the arms 110, so that the weight base 10 is raised.

[0060] As exemplarily shown in FIG. 11, the spacer elements 140 can be made of rectangular tubes with a short side 141 and a long side 142. For the height adjustment, the spacer elements 140 can then be connected to the arms 110 either via their long side 142 (see FIG. 12) or via their short side 141 (see FIG. 13). This makes it possible to set two different heights. The spacer elements 140 can be fastened with screws, for example, so that the fastening is removable. The sloping surface 116 of the angled base plate 115 preferably serves as the contact surface. If bearing bodies 130 are arranged there, they are dismantled beforehand. The dismantled bearing bodies 130 can then be attached to the spacer elements 140, so that they are indirectly attached to the arms 110 of the weight base 10 via the spacer elements 140. In this way, the displacement effect caused by the bearing bodies 130 can continue to be used.

[0061] Since not only the height of the reinforcement 4 can vary, but also the distance of the lattice girders usually used as reinforcement 4, a position can always be found by changing the angular position of the weight base 10 in relation to the ground, in which the spacer elements 140 can be placed on the thin concrete layer of the prefabricated element ceiling 3 between two lattice girders. FIG. 15 shows a large number of different angular positions at different distances from the reinforcement 4.
