Description

Technical Field

[0001] The present invention relates to an anchoring point for fixing to an object to be fixed and / or transported, comprising a connecting member for connecting the anchoring point to the object to be fixed and / or transported, the connecting member comprising an eyelet arc segment for connecting a body and a connecting eyelet for connecting an anchoring or strapping member, the connecting eyelet having a smaller radius in the arc segment in which it is hooked into the eyelet arc segment than in the other arc segments thereof, and the connecting eyelet carrying two partitioning elements which are arranged opposite to each other with respect to their longitudinal axes and extend into an inner cavity surrounded by the connecting eyelet. Background Art

[0002] This type of anchor is typically used for lifting objects. The anchor is connected to the object to be lifted or secured with its connecting element, which is usually a bolt. In many cases, this anchor is designed so that, when a lifting device is hooked into the connecting eyelet, the eyelet aligns according to the direction of the tensile force acting on it. In this type of anchor, the body that carries the eyelet arc is designed as an upper part that is rotatable relative to the lower part that carries the connecting element. This characteristic is also required for anchors used for tying objects, even if the anchor is not designed as an anchor swivel with an upper part that is rotatable relative to the lower part.

[0003] Depending on the specific situation, the applied tensile load can also act transversely on this anchoring point. To prevent the connecting eyelet from kinking within the eyelet arc segment of the main body, DE 10 2006 052 986 B4 proposes to hook a smaller radius arc segment of the connecting eyelet into the eyelet arc segment. Due to the smaller radius of this arc segment, two-point support of the arc segment within the eyelet arc segment is essentially avoided, thus enabling a better articulation of the connecting eyelet and the eyelet arc segment. Furthermore, in this known connection point, a partitioning element extends into the interior space enclosed by the connecting eyelet from each side connecting the arc segments. This partitioning element divides the interior space into an area where the eyelet arc segment is arranged and another area where an anchoring or strapping element can be suspended. The clear width between these partitioning elements is dimensioned so that the eyelet arc segment cannot pass through. This ensures that the smaller radius arc segment remains in its articulated position with the eyelet arc segment of the main body. These partitioning elements limit the depth of penetration of the connecting eyelet into the eyelet arc segment.

[0004] This known anchoring point is a considerable improvement in transverse loads compared to earlier anchoring points, but it would be desirable if the connecting eyelet could not kink relative to the eyelet arc even at an unfavourable angular position relative to the eyelet arc. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to propose an anchoring point that is improved in terms of being free of kinks, based on the above-mentioned background technology.

[0006] The solution of the present invention for achieving the above-mentioned purpose is an anchoring point of the same type as described at the beginning of this article, wherein the connecting eyelet is arranged opposite to the separating element with respect to its central fiber and carries on the outside a protruding movement limiting stop for limiting the insertion depth of the connecting eyelet into the eyelet arc segment, together with a separating element protruding on the inside which is also constructed as a movement limiting stop, through which the maximum diameter of the section of the connecting eyelet that carries the movement limiting stop is greater than the clear width of the eyelet arc segment, wherein the contour forming the movement limiting stop is formed so that there is basically only linear contact between the movement limiting stop and the eyelet arc segment in the anchoring device.

[0007] In addition to the separating element extending from the inside of the connecting eyelet, this connection point also features an outwardly extending movement-limiting stop. The movement-limiting stop is positioned opposite the separating element relative to the central fiber of the connecting eyelet and is so positioned that, in conjunction with the separating element, the penetration depth of the connecting eyelet into the eyelet arc is limited. The separating element also serves as a movement-limiting stop. Each pair of movement-limiting stops, comprising the inner-entering movement-limiting stop and the outwardly extending movement-limiting stop, is positioned relative to the connecting eyelet so that the connecting eyelet can be smoothly hinged to the eyelet arc segment that is engaged by the arc segment with the smaller radius. The movement-limiting stops are thus positioned to limit the penetration depth of the connecting eyelet, preventing any straight side segments from intersecting the eyelet arc segment, particularly in a specific length or arrangement, thereby creating a two-point support between the connecting eyelet and the eyelet arc segment. The movement-limiting stop pair is typically located at the end of the side edge, at the end facing the arc segment with the smaller radius.

[0008] Another characteristic of this connection point is that, in the anchoring position, essentially only linear contact occurs between one or both of the movement-limiting stops of the pair and the inner surface of the eyelet arc segment. The eyelet arc segment of this anchoring point is rounded on the inside to provide the desired hinge capacity. Therefore, the plane of the eyelet opening of the eyelet arc segment with the smaller diameter lies within its longitudinal center plane. This measure ensures that the two parts that can move toward each other—the connecting eyelet and the eyelet arc segment—do not become tangled due to the friction fit of the planes. This, combined with the aforementioned measure that only the curved surfaces come into contact during anchoring, allows the connecting eyelet to be easily separated from any lateral position with only minimal pulling force, so that, under minimal pulling force, the connecting eyelet can rest against the eyelet arc segment via the inner side of its arc segment hinged thereon.

[0009] According to a technical solution, the inner side surface of the arc segment of the connecting hole ring that is hung in the eyelet arc segment is rounded until the contour of the motion limiting stop, so that the inner side of the arc segment transitions to the contour of the motion limiting stop in a manner that continues the curved portion.

[0010] According to a particularly advantageous design of this anchoring point, the body and the eyelet arc form the upper part of the anchoring swivel, which is rotatable relative to the lower part carrying the or said connecting element. In this case, the inclination of the connecting eyelet relative to the eyelet arc is oriented not only in the direction of the applied tensile force but also in the circumferential direction. This improves the safety of this anchoring point against the aforementioned forces, particularly transverse forces. The rotatability of the upper part relative to the lower part can be achieved by means of corresponding bearings, such as plain bearings, or by the arrangement of one or more rolling elements therebetween.

[0011] In a weight-optimized embodiment, the cross-sectional area of ​​the respective section of the connecting eyelet in which the movement-limiting stop pair is arranged is no greater (at least not significantly greater) than the cross-sectional area of ​​the adjacent region of the connecting eyelet. This means that, in the region of the respective movement-limiting stop pair, the connecting eyelet has a reduced material thickness, viewed transversely to its extension. In a preferred embodiment, the inwardly projecting separation element is formed as a movement-limiting stop, and the outwardly projecting movement-limiting stop is formed from the connecting eyelet having a generally circular cross-sectional area in a single molding process transverse to the plane of the connecting eyelet. In this case, the connecting eyelet has the same cross-sectional area in this section as the adjacent unmolded section. Preferably, each movement-limiting stop of a movement-limiting stop pair transitions into the outwardly projecting movement-limiting stop via the width of the connecting eyelet section that carries it. The cross-sectional geometry can be the same throughout the connecting segment, with respect to the transition from the inward movement-limiting stop to the outward movement-limiting stop via the cross-sectional area of ​​this section. In this way, the connecting eyelet is not weakened because the connecting segment is only subjected to tension in the direction of its longitudinal extension and, due to the aforementioned measures, the connecting eyelet, optionally together with the rotatable upper part, is easily oriented in tension and not in a direction transverse to the connecting eyelet plane.

[0012] According to one embodiment, the side connecting the arc segments of the connecting eyelet is straight. In another embodiment, the side is S-shaped at least in one section. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Anchor point 1 is used to connect a specific object for transport, i.e., lifting, tying, or the like, depending on the application. Anchor point 1 comprises a lower part 2 and an upper part 3. Upper part 3 is rotatably supported relative to lower part 2. A bolt 4 is connected to the lower part, whose threaded section 5 is used to connect anchor point 1 to the object to be transported by screwing it into a correspondingly provided internally threaded hole in the object. Upper part 3 carries an eyelet segment 6, which, together with a portion of a body 7 of upper part 3, forms an eyelet. A connecting eyelet 8 is hooked into eyelet segment 6. The function of connecting eyelet 8 is to connect a lifting or tying member (such as a hook, rope, belt, or the like) to it. Connecting eyelet 8 is asymmetrical in its longitudinal extension and comprises a first segment 9 with a larger radius and a second segment 10 with a smaller radius. Connecting eyelet 8, with its smaller radius segment 10, hooks into eyelet segment 6 of upper part 3 and can be hinged thereto. In the illustrated embodiment, the sides 11 , 11 . 1 connecting the two arc segments 9 , 10 are straight and inclined to each other, so that the inner cavity I surrounded by the connecting eyelet 8 gradually narrows toward the arc segment 10 .

[0018] Connecting hole ring 8 relative Figure 1 The longitudinal centerline 12 is represented in this figure by its trajectory. Therefore, the two side edges 11 and 11.1 are structurally identical. Side edge 11 is described in detail below. The relevant explanation also applies to side edge 11.1.

[0019] The connecting eyelet 8 has, in principle, a circular cross-sectional geometry in its arc segments 9, 10 and in its sides 11, 11.1. In its region pointing towards the end of the arc segment 10 with the smaller radius, the side 11 carries a separating element 13 projecting inwardly into the interior space I, whose contour pointing towards the arc segment 10 forms a movement-limiting stop 14. The separating element 13, together with the separating element 13.1 of the side 11.1, divides the interior space I of the connecting eyelet 8 into an area where the eyelet arc segment 6 is hinged and an area of ​​greater clear width into which a hook or another lashing element is engaged or connected. Figure 2 For the virtual central longitudinal fiber M shown, a further movement-limiting stop 15 is arranged on the outside opposite the separating element 13, which is provided by a correspondingly shaped projection 16 (see Figure 2 In the embodiment shown, the partition element 13 and the protrusion 16 are provided by the flat portions on both sides of the side 11, see Figure 2sectional view. This flattening of the side 11 is symmetrical with respect to the center plane in the plane of the connecting eyelet 8. Due to this flattening, the cross-sectional area is not reduced compared to the section of the side 11 with a circular cross section. In the region of the flattening forming the two protruding structures, namely the separating element 13 and the projection 16, the cross-sectional area corresponds to the cross-sectional area of ​​the section of the side 11 with a circular cross section.

[0020] The contours of the movement-limiting stops 14, 15 formed by the partition element 13 and the projection 16 are rounded and, in the illustrated embodiment, do not have any straight sections located therebetween, in particular, no sections that play a relevant role in this context. The radius of the concave section of the movement-limiting stop 14 transitions into the radius of the arc segment 10.

[0021] The two movement limiting stops 14, 15 have an elongated S-shaped profile towards the arc segment 10. In the embodiment shown, the partition element 13 projects into the interior 1 by a multiple of the extent to which the projection 16 projects from the adjacent cylindrical side of the side 11.

[0022] Figure 3 The figure shows a cross-section of the anchor point 1 in the area of ​​its eyelet arc 6. As shown, the eyelet arc 6 is rounded on the side facing the eyelet opening. This radius matches the diameter of the arc 10 connecting the eyelet ring 8, so that the two components can be hinged together under normal circumstances. In the figure, the eyelet opening of the eyelet arc 6 is delimited on the bottom side by the upper end of the body 7. On this side of the eyelet opening, its clear width decreases in the direction of the longitudinal center plane 18 of the eyelet arc 6.

[0023] Figure 3 The connecting eyelet 8 is shown in a defined position with the arc 10 hooked into the eyelet arc 6, in which position the connecting eyelet is positioned relative to the eyelet. Figure 1 The position shown is deflected with the maximum permissible deflection amplitude at the anchor point 1. This deflection amplitude is approximately 80°. The deflectability of the side 11 to the maximum permissible penetration depth of the eyelet opening of the eyelet arc segment 6 is limited by the two movement limiting stops 14, 15. Figure 3 In the illustrated stop position, the convex section of the movement-limiting stop 14 contacts the upper curved inner side 17 of the eyelet arc 6, while the movement-limiting stop 15, likewise with its convex outer contour, abuts against the limit of the eyelet opening via the top side of the body 7. This stop-type abutment is circumferential. Due to the abutment of the curved contour, the penetration depth of the side edge 11 into the eyelet opening of the eyelet arc 6 is limited by linear contact.

[0024] If the connection point, i.e. the connection eyelet 8 of the anchor point 1, is subjected to the following Figure 3 The connecting eyelet can be easily pulled out of its Figure 3The position shown is pulled out, so that the inner side of the arc 10 rests against the eyelet arc 6, and the two components can be hinged together under normal circumstances. If a tensile force is applied to the connecting eyelet 8 perpendicular to the drawing plane, acting on the arc 9, the connecting eyelet 8 also easily aligns in the direction of the applied tensile force. When this force is applied, the upper part 3 rotates relative to the lower part 2 until the arc 9 points in the direction of the tensile force. At the same time, the connecting eyelet 8 is pulled into its normal hinged position with the eyelet arc 6.

[0025] The above measures effectively prevent the connecting eyelet 8 from getting kinked in or on the eyelet arc section 6 of the upper part 3.

[0026] In certain applications, it is necessary to apply a tensile force to the anchor point in order to transport it, said tensile force acting transversely to the longitudinal axis of the bolt. This can be achieved without any problems at this connection point, i.e. at the anchor point 1, without the risk of the connecting eyelet 8 getting stuck in this position on the eyelet arc 6.

[0027] Furthermore, the illustrated connection point, or anchor point 1, has an extremely high capacity for bearing transverse forces without the risk of the upper part 3 being torn off from the lower part 2. The present invention achieves this by virtue of the fact that the upper end of the lower part 2 carries a circumferential, radially protruding flange 19. This flange has a perfectly circular outer geometric contour. In the illustrated embodiment, the diameter of flange 19 corresponds to the diameter of the lower abutment flange 20, which is braced with its underside against the surface of the object to be transported. This flange 19 acts as a reinforcing annular body at the upper end of the lower part 2. This allows for the transmission of significant transverse forces to the upper part without the risk of the upper part being torn off from its receiving portion in the lower part or the upper receiving portion being torn apart laterally in the lower part.

[0028] To secure the lower part 2 to the object being transported, its radially outer side has several wrench flats 21. In the illustrated embodiment, these flats are arranged in a hexagonal pattern. The flange 19 radially overhangs the flats 21, providing effective protection not only against tearing of the upper part 3 but also against slipping of the tool (typically an open-end wrench) used to tighten the lower part 2 of the anchor point 1 to the object being transported.

[0029] The present invention is described with reference to one embodiment. A person skilled in the art will recognize numerous other solutions for implementing the present invention without departing from the scope of the present application, which are not listed here.
