[0003] Weight base for a mobile anchoring device, mobile anchoring device
[0004] The invention relates to a weight base for a mobile anchorage device for securing a person at risk of falling. Furthermore, the invention relates to a mobile anchorage device with a weight base according to the invention.
[0005] The preferred field of application of the invention is ceiling formwork systems for producing a ceiling or a ceiling section in concrete construction.
[0006] During the construction of a concrete ceiling or ceiling section using a slab formwork system, it may happen that a person has to work on a fall edge. This person must then be secured using a safety device. Safety devices are known that comprise a rope that is attached to the person being secured on one side and to an anchor point on the other. Mobile anchor devices are known to create such an anchor point. These are freely positioned on the work surface and secured in position by a load.
[0007] DE 20 2011 001 953 U1 provides an example of a load-supported anchorage device comprising a central weight base with an anchor point for a safety rope attached to it. The anchor point is fixed by the device's own weight. Limited displacement of the device under load, i.e., in the event of a fall, is permissible or even desirable, as it can cushion the fall. To improve the functional reliability of the load-supported anchorage device in the event of a fall, DE 20 2011 001 953 U1 proposes connecting the anchor point to the weight base via an energy-absorbing element. This element deforms under load, so that at least part of the falling energy or force is absorbed by the energy-absorbing element and converted into deformation energy.
[0008] The operating principle of a load-supported anchorage device is based on friction between the weight base and the surface on which the weight base or anchorage device is installed. However, this friction can be reduced, particularly if the surface is damp or wet. In this case, a film of moisture forms between the weight base and the surface, reducing friction and acting like a lubricating film. Under load, the device then begins to slide, which compromises its functional reliability.
[0009] The present invention is therefore concerned with the task of increasing the functional reliability of a load-supported mobile anchoring device, particularly on damp or wet surfaces.
[0010] To achieve this object, the weight base having the features of claim 1 and the mobile anchoring device having the features of claim 13 are proposed. Advantageous further developments of the invention can be found in the respective subclaims.
[0011] Disclosure of the invention
[0012] The proposed weight base for a mobile anchorage device for securing a person at risk of falling comprises a base body with several arms arranged at an angle to one another and weights as a load. Directly or indirectly attached to the underside of at least one arm is at least one anti-slip bearing body made of an elastomer material, which has a support surface that is inclined or spherical in a tilting direction of the weight base.
[0013] The proposed weight base therefore has at least one bearing body made of an elastomer material. The elastomer material has a damping effect because it is flexible. The elastomer material can be natural rubber, for example. Alternatively, other elastomers, such as IR, BR, SBR, EPM, or EPDM, can be used.
[0014] If, despite the dampening effect, the weight base tilts over the bearing body, for example in the event of a fall, this leads to a type of rolling movement of the bearing body on the ground, as the bearing body has a contact surface that is inclined or convex in the direction of tilt. If the ground is damp or wet, the moisture or wetness present on the ground is displaced by the bearing body during rolling, so that a film of moisture that reduces friction does not form between the bearing body and the ground. This displacement effect significantly reduces the risk of the weight base and the anchor device connected to the weight base sliding towards the edge on damp or wet ground. This increases the functional reliability of the weight base or the mobile anchor device.
[0015] A "convex" contact surface is one that exhibits a convex profile in at least one direction, namely the tilt direction. The contact surface can also be only approximately convex. This is the case, for example, if the contact surface has not just one inclined surface, but several inclined surfaces that are combined in a polygonal pattern to form an approximately convex contact surface. The phrase "contact surface that is inclined or convex in a tilt direction" also includes such configurations.
[0016] Preferably, at least one bearing element made of an elastomer material is arranged under each arm of the base body, so that the weight base only has contact with the ground via the bearing elements. This allows the damping effect to be further optimized.
[0017] Furthermore, it is proposed that not only is at least one bearing body made of an elastomer material arranged under each arm of the base body, but this bearing body also has a contact surface that is inclined or spherical in one tilting direction. The displacement effect previously described in connection with the inclined or spherical contact surface can thus be achieved in different tilting directions.
[0018] Due to the flexibility of the bearing bodies arranged beneath the arms of the base body, the weight base tends to tilt under load in a direction that coincides either with the longitudinal axis of an arm or with the angle bisector between the longitudinal axes of two adjacent arms. The number of arms and the resulting angular distances between the arms thus determine the preferred tilting directions. The contact surface of a bearing body made of elastomer material can be inclined or spherical in one or more tilting directions. The latter is the case, for example, when the contact surface is spherical. The spherical shape allows rolling in all directions. However, the spherical shape has the disadvantage that - due to the only point-like contact between the bearing body and the ground - the adhesion is reduced and the desired displacement effect is not achieved on damp or wet ground.This requires at least linear contact between the bearing body and the ground.
[0019] In a further development of the invention, it is therefore proposed that a plurality of anti-slip bearing bodies made of an elastomer material are directly or indirectly fastened to the underside of at least one arm, the contact surfaces of which are each designed to be inclined or spherical in a different tilting direction. These thus allow a rolling movement in different tilting directions. Preferably, a plurality of such anti-slip bearing bodies made of an elastomer material are directly or indirectly fastened to the underside of each arm. The preferred number of bearing bodies, whose contact surfaces are designed to be inclined or spherical, is three per arm, since there are three preferred tilting directions for a tilting movement over at least one arm, namely in the direction of the longitudinal extent or the longitudinal axis of the arm and in the direction of the two angle bisectors between the longitudinal axis of the arm and the longitudinal axes of the two adjacent arms.In each of these three tilting directions, a rolling movement can then be carried out via the respective bearing body with an inclined or spherical contact surface, which leads to the desired displacement effect on damp or wet ground.
[0020] According to a preferred embodiment of the invention, a plurality of bearing bodies have an elongated shape and are each inclined or spherical in the direction of their longitudinal extension. This configuration of the bearing bodies ensures at least linear contact between the bearing bodies and the ground to achieve the desired displacement effect. Preferably, a plurality of elongated bearing bodies of at least one arm are arranged at an angle to one another. The angular arrangement ensures that, depending on the tilting direction, at least one bearing body has at least linear contact with the ground.
[0021] The angular distance between two bearing bodies arranged at an angle to one another on an arm preferably corresponds to half the angular distance between the longitudinal axis of the arm and the longitudinal axis of the adjacent arm. For three elongated bearing bodies arranged at an angle to one another, the contact surface of the middle bearing body is preferably inclined or spherical in the longitudinal direction of the arm. The contact surfaces of the other two bearing bodies are each inclined or spherical in a different tilting direction.
[0022] If, for example, the base body has four arms that are each arranged at the same angular distance from one another, three elongated bearing bodies are preferably arranged under each arm, each at an angular distance of 45° from one another. The middle bearing body is arranged centrally in relation to the longitudinal axis of the respective arm. If a tilting movement occurs via one arm in the direction of the longitudinal axis of the arm, the middle bearing body rolls on the surface, ensuring at least linear contact. If a tilting movement occurs via two arms, so that the angle bisector between the longitudinal axes of the two arms determines the tilting direction, the bearing bodies of the two arms, which are aligned parallel to the angle bisector, roll on the surface, ensuring at least linear contact with the surface via these two bearing bodies.
[0023] In addition to at least one bearing body with a contact surface that is inclined or spherical in the tilting direction, each arm can also have at least one further bearing body made of elastomer material that has a flat contact surface. The flat contact surface increases the contact of the weight base with the ground, so that the weight of the weight base is distributed more evenly. The further bearing body with a flat contact surface is preferably arranged further inwards in relation to the at least one bearing body with a spherical contact surface. This ensures that during a tilting movement of the weight base, the further bearing body does not hinder the rolling over the bearing body with the spherical contact surface. If the further bearing body with a flat contact surface is elongated, it is preferably aligned transversely to the longitudinal axis of the arm.This measure also helps to ensure that the additional bearing body does not hinder the rolling over the bearing body with a crowned contact surface.
[0024] In a preferred embodiment of the invention, each arm has three bearing bodies made of elastomer material, each with a contact surface that is inclined or spherical in a tilting direction, and a further bearing body made of elastomer material with a flat contact surface, which is preferably arranged centrally in relation to the three other bearing bodies and further inward than them. This arrangement is reminiscent of a "tiger paw" in plan view. In a further development of the invention, it is proposed that the underside of at least one arm forms a plane at the end that runs inclined in a tilting direction for receiving the at least one bearing body. For this purpose, the underside can run inclined over its entire length or be angled at the end to form the incline. The incline is oriented in such a way that the distance of the arm from the ground increases towards its free end.In the area of the slope, at least one bearing body is attached directly or indirectly to the arm, so that in the event of a fall, the slope supports the rolling of the bearing body over the support surface which is inclined or crowned in the tilting direction during a tilting movement over the arm.
[0025] The direct attachment of the bearing bodies to the arms results in a low center of gravity for the weight base, which has a positive effect on its stability. However, a low center of gravity is not always an advantage.
[0026] For example, if the weight base or the mobile anchoring device containing the weight base is to be used in the construction of a prefabricated slab that, prior to completion, only has a thin layer of concrete and supporting steel lattice girders as reinforcement, the weight base is preferably placed over the reinforcement onto the thin layer of concrete. To do this, the center of gravity of the weight base must be raised.
[0027] As a further improvement, it is therefore proposed to install spacers between the arms and the bearing bodies. These spacers allow the weight base to be raised above the substructure, thus preventing the reinforcement from being stressed by the weight base. This advantage is not only important in the construction of prefabricated floor slabs, but also whenever the substructure is uneven.
[0028] Advantageously, the spacers are detachably attached to the arms. They can then be used as needed. If spacers are no longer required, they can be removed, thus restoring the advantage of a low center of gravity of the weight base. The detachable connection can be established using screws or other fastening means, for example. Preferably, the bearing bodies are detachably attached to the arms in the same way, directly or indirectly via the spacers. These can then be removed and reattached to the spacers after the spacers have been attached to the arms.
[0029] Furthermore, it is suggested that the spacers be height-adjustable. For example, spindle feet or telescopic legs can be used as spacers.
[0030] According to a preferred embodiment of the invention, the spacer elements are made of rectangular tubes. These are particularly easy to manufacture and have flat outer surfaces for contact with the arms and for receiving the bearing bodies. Furthermore, the spacer elements are preferably releasably attached to the arms via a short side or a long side. The height of the weight base can be varied depending on whether the spacer elements contact the arms via their short side or their long side.
[0031] Furthermore, in the proposed weight base, the weights are preferably arranged eccentrically, preferably above the bearing bodies. This eccentric arrangement results in a favorable mass distribution, which further improves the stability of the weight base. In the event of a fall, the eccentric arrangement creates a maximally effective ballast lever arm that counteracts the tipping moment. The arrangement of the weights above the bearing bodies ensures maximum contact pressure, which also acts as a slip-resistant barrier.
[0032] The weights serving as "loads" do not necessarily have to be arranged on the arms. In an advantageous embodiment of the invention, the weights are accommodated in the arms. Preferably, the arms of the base body for accommodating the weights are at least partially tubular and / or hollow. The weights can thus be inserted into the arms. This ensures that the weights do not pose a safety hazard, in particular a tripping hazard.
[0033] Moving a weight base usually requires an auxiliary device, such as a lifting device and / or a crane.
[0034] In a further development of the invention, it is therefore proposed that the undersides of the arms be stepped to accommodate a lifting device. This stepped design results in a preferably centrally located free space between the base body and the ground, so that the lifting device can be retracted into this area. Furthermore, it is proposed that the base body form transport aids, for example in the form of crane eyes. The crane eyes can be designed as recesses in the base body, preferably as end-side recesses in the arms of the base body. In this case, each arm of the base body can be connected to a cable so that the mass of the weight base is evenly distributed during transport by crane.
[0035] Alternatively or additionally, it is proposed that the base body form stacking aids, for example in the form of tabs and corresponding recesses. The tabs and recesses are preferably provided on opposite sides of the base body, so that when two base bodies are stacked on top of each other, the tabs of one base body engage in the recesses of the other base body and create a positive connection that prevents any relative movement of the two base bodies.
[0036] The base body of a weight base according to the invention preferably has at least four arms. The stability increases with the number of arms, with four arms being sufficient. Furthermore, the arms are preferably arranged in a common plane and / or at the same angular distance from one another. By arranging the arms in one plane, the weight base can be designed very flat, which promotes a low center of gravity. At the same time, the top of the base body can be designed flat. The equal angular distance between the arms ensures that the tipping tendency is the same across all arms.
[0037] Furthermore, the base body preferably has a central part with receptacles for connecting means of an anchor element, which comprises a mast for attaching a safety device, in particular a rope. The central part or the central part can be designed as a separate part or integrally with the base body. The central arrangement of the anchor element and the mast also contributes to ensuring that the tendency to tip is the same, in particular equally low, in all directions. Furthermore, depending on the design of the connecting means, a detachable connection between the anchor element and the weight base can be established via the receptacles in the central part. The detachable connection has the advantage that, after the anchor element has been removed, several weight bases can be stacked on top of one another, which simplifies the transport and / or storage of the weight base.Furthermore, a mobile anchoring device for a safety device is proposed, which comprises a weight base according to the invention and an anchor element connected to the weight base with a mast for attaching the safety device, in particular a rope. The anchor element is preferably detachably connected to the weight base so that it can be removed if necessary, for example during transport and / or storage of the weight base. The connection is preferably made in the region of a central part of the base body of the weight base so that the anchor element and the mast are arranged centrally with respect to the base body. The arms then form cantilevers, via which the mobile anchoring device can be optimally supported in the event of a fall.If the anchorage device tilts over at least one arm of the weight base on damp or wet ground, the angled or spherical contact surface of the bearing body located under the arm causes a rolling movement, which displaces the moisture present between the weight base and the ground. This displacement effect prevents a film of moisture from forming between the weight base and the ground, which reduces friction and thus grip. Accordingly, the tendency of the mobile anchorage device to slip is reduced.
[0038] Since the mast of the anchor element is typically vertically aligned and positioned centrally above the weight base, a fall quickly leads to a tipping movement of the mobile anchorage device. This tipping movement increases the contact pressure of the at least one bearing body on the ground over which the rolling movement is carried out, thus further increasing the displacement effect.
[0039] The anchor element preferably has mechanical connecting means for detachable connection to the weight base. For example, mechanical connecting means can be provided in the form of claws. The claws are preferably arranged movably so that they can be brought into locking engagement with recesses in the base body of the weight base.
[0040] As already mentioned, the mast is preferably positioned centrally with respect to the weight base. This means that the attachment point is located centrally above the weight base. Alternatively or additionally, it is proposed that the mast be designed as a telescopic tube. This allows the height of the attachment point to be adjusted as needed. This may be necessary, for example, if spacers are arranged on the underside of the base body so that it is raised. At the same time, the center of gravity of the weight base is raised, increasing the tendency to tip over and the tipping moment. This disadvantage can be largely compensated for by reducing the mast height or by lowering the attachment point.

[0057] Detailed description of the drawings
[0058] The mobile anchorage device 1 shown in Figure 1 comprises a weight base 10 and an anchor element 20. The anchor element 20 comprises a central mast 21, on which an attachment 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, via which the anchor element 20 is detachably connected to the weight base 10.
[0059] The weight base 10 comprises a base body 100 with four arms 110 as cantilevers. The arms 110 are each tubular and / or hollow in their end sections, i.e., at their free ends, to accommodate weights 120. 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.
[0060] The base body 100 is mounted on bearing bodies 130 made of an elastomer material, which have an anti-slip effect. The bearing bodies 130 are arranged below the arms 110 at their free ends, so that the load of the weights 120 rests on the bearing bodies 130. On the upper side, the arms 110 have recesses, which, together with recesses in the weights 120, form crane eyes 114. In the area of the crane eyes 114, the weight base 10 or the mobile attachment device 1 can be connected to a 4-leg crane sling. On the upper side, the arms 110 also form lugs.
[0061] 112, which serve as stacking aids. When the weight bases 10 are stacked on top of each other, the tabs 112 of the lower weight base 10 engage in corresponding recesses
[0062] 113 of the weight base 10 located above. Relative movement of the weight bases 10 to one another is thus blocked. The arms 110 of the weight base 10 shown in Figure 1 converge in a central part 150, which has receptacles 151 for the connecting means 22 of the anchor element 20 for releasable connection to the base body 100. The connecting means 22 are in the form of claws that can be inserted into the receptacles 151 and brought into locking engagement with the base body 100 (see Figures 2, 10, and 11). The central part 150 also forms four tensioning strap receptacles 152, each of which is arranged laterally on the central part 150 between two arms 110.
[0063] The weights 120 accommodated in the arms 110 are plate-shaped, with several plate-shaped weights 120 each forming a plate pack accommodated in an arm 110. The individual plate-shaped weights 120 are arranged upright. The weights 120 can thus be inserted individually or as a plate pack into the tubular and / or hollow end sections of the arms 110. Insertion preferably occurs from the inside outward, since—as can be seen in particular from Figures 3, 4, and 5—the arms 110 have undersides 111 that slope toward the end or form sloped surfaces 116. In the present case, the sloped surfaces 116 are each formed by angled base plates 115. Each base plate 115 simultaneously forms a stop 122 for the plate-shaped weights 120, so that the end position of the weights 120 is predetermined via the stop 122.This facilitates the insertion of screw bolts 121, by means of which the weights 120 are fixed in the arms HO. Since the weights 120 are held upright in the arms 110, the screw bolts 121 can be arranged transversely thereto, so that their heads and the nuts screwed on at the other ends each lie laterally on the arms 110.
[0064] The bearing bodies 130 are also arranged in the area of the angled base plates 115. As can be seen in particular from Figures 2, 3, 4, and 5, several 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 centrally below 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, each of which is arranged at the same angular distance a from the first bearing body 130. The angular distance a—measured between the longitudinal axes of the bearing bodies 130—is 45° in this case (see in particular Figure 5). The three bearing bodies 130 each have a contact surface 131 which is spherically shaped in the longitudinal direction of the bearing bodies 130 (see in particular Figure 4).Outside the inclined surface 116, a further bearing body 130' is fastened to the base plate 115, which is aligned transversely to the longitudinal direction of the arm 110 and has a flat contact surface 131' (see in particular Figure 4).
[0065] In the event of a fall, a tensile force F acts on the attachment point 23, causing a tipping moment such that the weight base 10 executes a tipping movement (see Figure 6). The weight base 10 then rolls over at least one bearing body 130 with a spherically shaped contact surface 131, since the contact surface 131 of the bearing body 130 is spherically shaped in the respective tipping direction 133. On a damp or wet surface, this rolling movement achieves a displacement effect that prevents the formation of a moisture film between the bearing body 130 and the surface, which reduces friction. This reduces the risk of the weight base 10 sliding on a moisture film towards the edge of the fall. The arrangement of the bearing bodies 130 in the area of the inclined surfaces 116 further enhances the displacement effect, since a maximum rolling distance is achieved for a given size of the bearing bodies.
[0066] As shown by way of example in Figures 7 and 8, the weight base 10 has preferred tilting directions 133. It tilts either via one arm 110 (Figure 7) or via two arms 110 (Figure 8).
[0067] If it tilts over an arm 110 (Figure 7), it rolls over the centrally arranged bearing body 130 of this arm 110, since the contact surface 131 of the central bearing body 130 is spherically shaped in the longitudinal direction of the arm 110 and thus in the tilting direction 133. The elongated shape of the bearing body 130 ensures at least linear contact between the bearing body 130 and the ground, thus achieving the desired displacement effect. The linear contact is indicated in Figure 7 by a line 132.
[0068] If the weight base 10 tilts over two arms 110 (Figure 8), it rolls over two bearing bodies 130, which are each arranged on the outside of the two arms 110 and each have a spherically shaped contact surface 131 in the tilting direction 133. The elongated shape of the bearing bodies 130 ensures at least linear contact with the ground in this case as well, which is required to achieve the displacement effect. The linear contact is indicated in Figure 8 by lines 132. Due to the elasticity of the bearing bodies, they deform under load. It can therefore be assumed that during rolling, there is not only linear contact, but also planar contact between the respective bearing body(s) and the ground.
[0069] If the weight base 10 does not perform a tilting movement, it rests essentially on the four bearing bodies 130', whose contact surfaces 131' are flat.
[0070] Figure 9 shows the mobile anchorage device 1 in a top view. The anchor element 20 is detachably connected to the weight base 10 via the central part 150 of the base body 100. The detachable connection is established via the connecting means 22, which form claws (see in particular Figure 10). The claws are inserted into the receptacles 151 of the central part 150 and then brought into locking engagement with the base body 100 (see in particular Figure 11). For this purpose, one claw is designed to be movable, in particular pivotable (see in particular Figure 10).
[0071] As can also be seen from Figure 11, the undersides 111 of the arms 110 are stepped, so that further inside, the distance of the base body 100 from the ground is greater than in the area of the end sections of the arms 110 that accommodate the weights 120. This free space can be used - as shown by way of example in Figure 12 - to accommodate a lifting device 2. With the aid of the lifting device 2, the weight base 10 or the mobile anchor device 1 can be easily relocated.
[0072] The illustrated weight base 10 is low in height, so its center of gravity is low. This low center of gravity results in favorable mass distribution, thus ensuring high stability for the weight base 10. To enable the weight base 10 to be used on uneven subfloors and / or during the construction of prefabricated ceilings with a thin concrete layer and steel mesh reinforcements resting on top, the weight base 10 can be combined with spacer elements 140. These are attached to the undersides 111 of the arms 110, raising the weight base 10. The base body 100 then rests above the reinforcement.
[0073] Figure 13 shows an example of a spacer element 140 made from a rectangular tube and having a short side 141 and a long side 142. For height adjustment, the spacer element 140 can be connected to an arm 110 of the base body 100 either via its long side 142 (see Figure 14) or via its short side 141 (see Figure 15). The spacer elements 140 can be attached to the base body 100 using screws, so that the attachment is detachable. The inclined surface 116 of the angled base plate 115 preferably serves as the contact surface. If bearing bodies 130 are arranged there, they are removed beforehand. The removed 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.
