Description

[0001] The invention relates to a weight base for a mobile anchor device for securing a person at risk of falling. Furthermore, the invention relates to a mobile anchor device with a weight base according to the invention.

[0002] The preferred application area of ​​the invention is ceiling formwork systems for the production of a ceiling or a ceiling section in concrete construction.

[0003] When constructing a concrete slab or slab section using a slab formwork system, it sometimes happens that a person has to work at a fall edge. This person must then be secured with a safety device. Known safety devices include 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 for creating such an anchor point; these are freely positioned on the work surface and secured in place by a weight.

[0004] German patent application DE 20 2011 001 953 U1 describes an exemplary ballast-supported anchor device that has a central weight base with an anchor point for a safety rope to which it is attached. 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 dampen the fall. To improve the functional reliability of the ballast-supported anchor device in the event of a fall, DE 20 2011 001 953 U1 proposes that the anchor point be connected to the weight base via an energy-absorbing element. This element deforms under load, so that at least some of the fall energy is absorbed by the energy-absorbing element and converted into deformation energy.Fener's British patent application GB 2 330 169 A discloses an improved deadweight anchor for use as a safety anchor for supporting workers on flat-roofed buildings in the event of a fall, comprising at least one deformable element connected to at least one weight and at least one attachment point for a user support device. According to Austrian utility model AT 13 023 U1, a ballast-supported anchor device comprising a central weight base, in particular a multi-armed boom, with an attachment point for a safety rope to be attached thereto, proposes connecting the attachment point to the weight base via an energy-absorbing element.European patent EP 3 428 343 B1 also proposes a screen for shielding accidents, with a support structure consisting of one or more support elements having vertical support posts and covered or planked with a sheet of an opaque material and held in feet, wherein each foot has an elongated plate which is provided on its underside, at least in some areas, with a friction-enhancing coating.

[0005] The operating principle of a ballast-mounted lifting device is based on friction between the weight base and the surface on which the weight base or lifting device is mounted. However, this friction can be reduced, particularly when 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 lubricant. Under load, the device then begins to slide, compromising its reliable operation.

[0006] The present invention is therefore concerned with the objective of increasing the functional reliability of a ballast-mounted mobile anchor device, particularly on damp or wet surfaces.

[0007] To solve the problem, the weight base with the features of claim 1 and the mobile stop device with the features of claim 12 are proposed. Advantageous embodiments of the invention can be found in the respective dependent claims. Disclosure of the invention

[0008] The proposed weight base for a mobile anchor device used to secure a person at risk of falling has a base body with several arms arranged at angles to each other, as well as weights as a load. Several anti-slip bearing bodies made of an elastomeric material are attached directly or indirectly to the underside of at least one arm, their contact surfaces being inclined or convex in opposite directions of tilt of the weight base.

[0009] The proposed weight base therefore features several bearing elements made of an elastomeric material. The elastomeric bearing element has a damping effect due to its flexibility. The elastomeric material could be, for example, natural rubber. Alternatively, other elastomers such as IR, BR, SBR, EPM, and EPDM could be used.

[0010] If, despite the damping effect, the weight base tilts over the bearing body, for example in the event of a fall, this results in a kind of rolling motion of the bearing body on the surface, since the bearing body has a contact surface that is angled or convex in the direction of tilting. If the surface is damp or wet, the moisture or wetness present on the surface is displaced by the bearing body during this rolling motion, preventing a film of moisture from forming between the bearing body and the surface, which would reduce friction. This displacement effect significantly reduces the risk of the weight base and the attached anchor device sliding towards the edge of the fall when the surface is damp or wet. This increases the operational reliability of the weight base and the mobile anchor device.

[0011] A contact surface is described as "convex" if it has a convex shape in at least one direction, specifically in the direction of tilting. The contact surface can also be only approximately convex. This is the case, for example, if the contact surface has not just one sloping surface, but several sloping surfaces that are arranged in a polygonal pattern to form an approximately convex contact surface. The phrase "contact surface sloping or convex in one direction of tilting" also includes such configurations.

[0012] Preferably, bearing elements made of an elastomeric material are arranged under each arm of the base body, so that the weight base only makes contact with the surface via the bearing elements. This allows the damping effect to be further optimized.

[0013] Furthermore, it is proposed that not only are several bearing bodies made of an elastomer material arranged under each arm of the base body, but that the base body also has a contact surface that is inclined or convex in one tilting direction. The displacement effect previously described in connection with the inclined or convex contact surface can thus be achieved in different tilting directions.

[0014] Due to the flexibility of the bearing bodies arranged under the arms of the base, the weight base tends to tip under load in a direction that coincides either with a longitudinal axis of one arm or with the bisector of the angle between the longitudinal axes of two adjacent arms. The number of arms and the resulting angular distances between them thus determine the preferred tipping directions.

[0015] The contact surface of a bearing body made of elastomer material can be inclined or convex in one or more tilting directions. The latter is the case, for example, when the contact surface is spherically shaped. The spherical shape allows rolling in all directions. However, the spherical shape has the disadvantage that—due to the only point contact between the bearing body and the substrate—adhesion is reduced, and the desired displacement effect does not occur on damp or wet substrates. For this to be effective, at least line contact between the bearing body and the substrate is required.

[0016] According to the invention, several anti-slip bearing bodies made of an elastomeric material are attached directly or indirectly to the underside of at least one arm, the contact surfaces of which are each inclined or convex in a different tilting direction. These thus allow a rolling movement in different tilting directions. Preferably, several such anti-slip bearing bodies made of an elastomeric material are attached directly or indirectly to the underside of each arm. The preferred number of bearing bodies with an inclined or convex contact surface is three per arm, since there are three preferred tilting directions when tilting over at least one arm: namely, in the direction of the longitudinal extent or longitudinal axis of the arm, and in the direction of the two bisectors of the angle 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 its inclined or convex contact surface, which leads to the desired displacement effect on damp or wet surfaces.

[0017] According to the invention, several bearing bodies have an elongated shape and are each inclined or convex in the direction of their longitudinal extent. In this configuration of the bearing bodies, at least linear contact between the bearing bodies and the substrate is ensured in order to achieve the desired displacement effect. Preferably, several elongated bearing bodies of at least one arm are arranged at an angle to one another. The angled arrangement ensures that, depending on the tilting direction, at least one bearing body has at least linear contact with the substrate.

[0018] The angular distance between two bearing bodies arranged at an angle to each other 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. In the case of three elongated bearing bodies arranged at an angle to each other, the contact surface of the middle bearing body is preferably inclined or convex in the longitudinal direction of the arm. The contact surfaces of the other two bearing bodies are each inclined or convex in a different tilting direction.

[0019] For example, if the base body has four arms, each arranged at the same angular distance from the others, preferably three elongated bearing bodies are arranged under each arm at angular intervals of 45° to each other. The middle bearing body is positioned centrally with respect to the longitudinal axis of the respective arm. If a tilting movement occurs over one arm in the direction of the arm's longitudinal axis, the middle bearing body rolls on the surface, ensuring at least linear contact. If a tilting movement occurs over two arms, such that the bisector of the angle between the longitudinal axes of the two arms determines the tilting direction, the bearing bodies of the two arms, aligned parallel to the bisector, roll on the surface, ensuring at least linear contact with the surface via these two bearing bodies.

[0020] In addition to the bearing bodies with a contact surface that is inclined or convex in the tilting direction, each arm can also have at least one further bearing body made of elastomer material with a flat contact surface. The flat contact surface increases the contact between the weight base and the substrate, thus distributing the weight of the weight base more evenly. The further bearing body with a flat contact surface is preferably positioned further inwards relative to the bearing bodies with convex contact surfaces. This ensures that, in the event of a tilting movement of the weight base, the further bearing body does not impede its rolling motion over the bearing bodies with convex contact surfaces. If the further bearing body with a flat contact surface is elongated, it is preferably oriented transversely to the longitudinal axis of the arm.This measure also helps to ensure that the additional bearing body does not impede rolling over the bearing body with its convexly designed contact surface.

[0021] In a preferred embodiment of the invention, each arm has three bearing bodies made of elastomeric material, each with a contact surface that is inclined or convex in a tilting direction, and a further bearing body made of elastomeric material with a flat contact surface, which is preferably arranged centrally with respect to the other three bearing bodies and further inwards than them. In a top view, this arrangement resembles a "tiger's paw".

[0022] In a further development of the invention, it is proposed that the underside of at least one arm forms a plane at its end, inclined in a tilting direction, to receive the at least one bearing body. For this purpose, the underside can be inclined along its entire length or angled at its end to form the incline. The incline is oriented such that the distance between the arm and the ground increases towards its free end. In the area of ​​the incline, the bearing bodies are attached directly or indirectly to the arm, so that in the event of a fall, the incline assists the bearing body in rolling over the contact surface, which is inclined or convex in the tilting direction.

[0023] Directly attaching 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.

[0024] For example, if the weight base or the mobile support device comprising the weight base is to be used in the production of a precast concrete slab which – before its 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 concrete layer. For this purpose, the center of gravity of the weight base must be raised.

[0025] As a further development measure, it is therefore proposed that spacer elements be arranged between the arms and the bearing bodies. These spacer elements allow the weight base to be raised relative to the substrate, thus preventing the reinforcement from being stressed by the weight base. This advantage is not only relevant in the production of precast concrete slabs, but also whenever the substrate is uneven.

[0026] Advantageously, the spacers are detachably attached to the arms. They can then be inserted as needed. If no spacers are required, they can be removed, thus restoring the advantage of a low center of gravity for the weight base. The detachable connection can be made, for example, using screws or other fasteners. Preferably, the bearing bodies are similarly detachably attached to the arms directly or indirectly via the spacers. They can then be removed and, after the spacers have been attached to the arms, reattached to the spacers.

[0027] Furthermore, it is proposed that the spacers be height-adjustable. For example, spindle feet or telescopic legs can be used as spacers.

[0028] 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, preferably, the spacer elements are detachably attached to the arms via either a short side or a long side. Depending on whether the spacer elements contact the arms via their short side or their long side, the height of the weight base can be varied.

[0029] Furthermore, in the proposed weight base, the weights are preferably arranged eccentrically, ideally 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 provides slip resistance.

[0030] The weights serving as "surcharge" do not necessarily have to be arranged on the arms. In an advantageous embodiment of the invention, the weights are housed within the arms. Preferably, the arms of the base body are designed, at least partially, to be tubular and / or hollow to accommodate the weights. The weights can thus be inserted into the arms. This ensures that the weights do not constitute a safety hazard, in particular not a tripping hazard.

[0031] Moving a weight base usually requires an auxiliary device, such as a lifting device and / or a crane.

[0032] In a further development of the invention, it is therefore proposed that the undersides of the arms be designed with steps to accommodate a lifting device. The stepped design results in a preferably centrally located gap between the base body and the surface, so that the lifting device can be inserted into this area.

[0033] Furthermore, it is proposed that the base body incorporate transport aids, for example in the form of crane lugs. The crane lugs can be designed as recesses in the base body, preferably as end recesses in the arms of the base body. In this case, each arm of the base body can be connected with a rope, so that the mass of the weight base is evenly distributed during transport by crane.

[0034] Alternatively or additionally, it is proposed that the base body incorporates 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, the tabs of one base body engage in the recesses of the other base body, creating a positive fit that prevents relative movement between the two base bodies.

[0035] Preferably, the base body of a weight base according to the invention has at least four arms. The stability increases with the number of arms, with four arms being sufficient. Furthermore, preferably the arms are arranged in a common plane and / or at the same angular distance from one another. Arranging the arms in a single plane allows the weight base to be very flat, which results in a low center of gravity. At the same time, the top surface of the base body can be flat. The equal angular distance between the arms ensures that the tendency to tip is the same across all arms.

[0036] Furthermore, the base preferably has a central section with receptacles for connecting elements of an anchor element, which includes a mast for attaching a safety device, in particular a rope. The central section can be designed as a separate part or integrally with the base. The central arrangement of the anchor element and the mast also contributes to ensuring that the tendency to tip is the same, and in particular equally low, in all directions. Depending on the design of the connecting elements, the receptacles in the central section also allow for a detachable connection between the anchor element and the weight base. This detachable connection has the advantage that, after removing the anchor element, several weight bases can be stacked on top of each other, which simplifies the transport and / or storage of the weight base.

[0037] Furthermore, a mobile anchor device for a safety device is proposed, comprising 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 area of ​​a central section 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 outriggers by which the mobile anchor device can be optimally supported in the event of a fall.If the lifting device tilts on at least one arm of the weight base when placed on damp or wet ground, the angled or convex contact surface of the bearing body located under the arm causes a rolling motion, displacing any 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 would reduce friction and thus adhesion. Consequently, the tendency of the mobile lifting device to slip is reduced.

[0038] Since the mast of the anchor element is typically vertically oriented and positioned centrally above the weight base, a fall quickly leads to a tilting motion of the mobile anchor device. This tilting motion increases the contact pressure of the bearing body on the ground, which is responsible for the rolling motion, thus further increasing the displacement effect.

[0039] Preferably, the anchor element has mechanical connecting means for a detachable connection to the weight base. For example, mechanical connecting means can be in the form of claws. Preferably, the claws are movably arranged so that they can be brought into a latching engagement with recesses in the base body of the weight base.

[0040] As previously mentioned, the mast is preferably positioned centrally with respect to the weight base. This means that the attachment point is located directly above the weight base. Alternatively or additionally, it is proposed that the mast be designed as a telescopic tube. This allows for height adjustment of the attachment point if necessary. This might be necessary, for example, if spacers are attached to the underside of the base, raising it. Simultaneously, this raises the center of gravity of the weight base, increasing the tendency to tip and the tipping moment. This disadvantage can be largely compensated for by reducing the mast height or by lowering the attachment point.

Detailed description of the drawings

[0042] The one in Figure 1The illustrated mobile anchor device 1 has a weight base 10 and an anchor element 20. The anchor element 20 comprises a central mast 21 on which an anchor point 23 for a safety device, in particular for a rope, is formed. At its other end, the anchor element 20 has connecting means 22 by which the anchor element 20 is detachably connected to the weight base 10.

[0043] The weight base 10 has a base body 100 with four arms 110 as outriggers. The arms 110 are designed to accommodate weights 120 in their end sections, i.e., at their free ends, and are each tubular and / or hollow. The weights 120 are integrated into the arms 110 in the region of the end sections. This results in an eccentric arrangement of the weights 120 and consequently in a particularly favorable mass distribution.

[0044] The base body 100 is mounted on bearing bodies 130 made of an elastomeric material, which have a non-slip effect. The bearing bodies 130 are arranged under the arms 110 at their free ends, so that the load of the weights 120 rests on the bearing bodies 130. The arms 110 have recesses on their upper side, which, together with recesses in the weights 120, form crane lifting eyes 114. In the area of ​​the crane lifting eyes 114, the weight base 10 or the mobile lifting device 1 can be connected to a 4-leg sling of a crane. The arms 110 also form tabs 112 on their upper side, which serve as stacking aids. When weight bases 10 are stacked on top of each other, the tabs 112 of the lower weight base 10 engage in corresponding recesses 113 of the weight base 10 above it. In this way, a relative movement of the weight bases 10 to each other is blocked.

[0045] The arms 110 of the in the Figure 1The depicted weight base 10 converges in a central section 150, which has receptacles 151 for the connecting elements 22 of the anchor element 20 for detachable connection with the base body 100. The connecting elements 22 have the form of claws that can be inserted into the receptacles 151 and brought into a snap-fit ​​engagement with the base body 100 (see Figure 2 , 10 and 11 The central section 150 also forms four tension strap receptacles 152, each of which is arranged laterally on the central section 150 between two arms 110.

[0046] The weights 120 accommodated in the arms 110 are plate-shaped, with several plate-shaped weights 120 forming a plate stack accommodated in each arm 110. The individual plate-shaped weights 120 are arranged upright. The weights 120 can thus be inserted individually or as a plate stack into the tubular and / or hollow end sections of the arms 110. Insertion preferably occurs from the inside out, since – as is particularly evident from the Figure 3 , 4 and 5As can be seen, the arms 110 have undersides 111 that slope towards their ends or form sloping surfaces 116. These 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, thus defining the end position of the weights 120. This facilitates the insertion of screw bolts 121, which fix the weights 120 in the arms 110. Since the weights 120 are held upright in the arms 110, the screw bolts 121 can be arranged transversely to them, so that their heads and the nuts screwed onto the other ends lie laterally against the arms 110.

[0047] The bearing bodies 130 are also arranged in the area of ​​the angled base plates 115. As can be seen in particular from the Figure 2, 3 , 4 and 5As can be seen, several bearing bodies 130 are arranged on the underside 111 of each arm 110. These are each elongated and arranged at angles 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 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, each arranged at the same angular distance α from the first bearing body 130. The angular distance α – 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 convex in the longitudinal direction of the bearing bodies 130 (see in particular Figure 4Outside the inclined surface 116, another bearing body 130' is attached to the base plate 115, which is oriented transversely to the longitudinal direction of the arm 110 and has a flat contact surface 131' (see in particular Figure 4 ).

[0048] In the event of a fall, a tensile force F acts at the anchor point 23, causing a tipping moment so that the weight base 10 performs a tipping movement (see Figure 6The weight base 10 then rolls over at least one bearing body 130 with a convexly shaped contact surface 131, since the contact surface 131 of the bearing body 130 is convex in the respective tilting direction 133. On a damp or wet surface, this rolling motion creates a displacement effect that prevents the formation of a moisture film between the bearing body 130 and the surface, which would reduce friction. This reduces the risk of the weight base 10 sliding towards the edge of the fall on a film of moisture. The displacement effect is further enhanced by arranging the bearing bodies 130 in the area of ​​the inclined surfaces 116, as this achieves a maximum rolling distance for a given size of the bearing bodies.

[0049] As exemplified in the Figure 7 and 8 As shown, the weight base 10 has 10 preferred tilting directions 133. It tilts either via an arm 110 ( Figure 7) or over two arms 110 ( Figure 8 ).

[0050] Provided it tips 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 convex 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 substrate, so that the desired displacement effect is achieved. The linear contact is in the Figure 7 indicated by line 132.

[0051] Provided the weight base 10 tips over two arms 110 ( Figure 8), it rolls over two bearing bodies 130, each of which is arranged externally on the two arms 110 and each has a convexly shaped contact surface 131 in the tilting direction 133. The elongated shape of the bearing bodies 130 ensures at least linear contact with the substrate in this case as well, which is necessary to achieve the displacement effect. The linear contact is in the Figure 8 indicated by line 132.

[0052] Due to the elasticity of the bearing bodies, they deform under load. It can therefore be assumed that during rolling, contact between the respective bearing body(s) and the substrate occurs not only linearly, but also over a surface area.

[0053] Provided that 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.

[0054] Figure 9 Figure 1 shows the mobile stop 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 made via the connecting elements 22, which form claws (see in particular Figure 1). Figure 10 The claws are inserted into the receptacles 151 of the middle section 150 and then brought into a locking engagement with the base body 100 (see in particular Figure 11 For this purpose, a claw is designed to be movable, in particular pivotable (see in particular Figure 10 ).

[0055] How further the Figure 11 As can be seen, the undersides 111 of the arms 110 are stepped, so that further inwards the distance between the base body 100 and the substrate is greater than in the area of ​​the end sections of the arms 110 that receive the weights 120. This clearance can be – as exemplified in the Figure 12As shown, it can be used to accommodate a lifting device 2. The weight base 10 or the mobile stop device 1 can be easily repositioned using the lifting device 2.

[0056] The depicted weight base 10 has a low height, resulting in a low center of gravity. This low center of gravity leads to a favorable mass distribution, giving the weight base 10 high stability. To enable the use of the weight base 10 even on uneven surfaces and / or during the production of precast concrete slabs with a thin layer of concrete and steel mesh reinforcement on top, the weight base 10 can be combined with spacer elements 140. These are attached to the undersides 111 of the arms 110, thus raising the weight base 10. The base body 100 then rests above the reinforcement.

[0057] In the Figure 13An example of a spacer element 140 is shown, which is made of a rectangular tube and has a short side 141 and a long side 142. For height adjustment, the spacer element 140 can be adjusted either via its long side 142 (see Figure 14 ) or via its short page 141 (see Figure 15 ) are connected to an arm 110 of the base body 100.

[0058] The spacer elements 140 can be attached to the base body 100 by means of 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, these are removed beforehand. The removed bearing bodies 130 can then be attached to the spacer elements 140, so that the spacer elements 140 are indirectly attached to the arms 110 of the weight base 10. In this way, the displacement effect caused by the bearing bodies 130 can still be utilized. Reference symbol list
