Description

The present invention relates to an attachment point for coupling with pulling, lifting or lashing means according to the features in the preamble of claim 1.

Attachment points are used to form on a to be lifted or fixed object that has no attachment points per se, such. For example, such an attachment point may be attached to a container or other load to be lifted or moved. Alternatively, an anchorage point can also be mounted on a loading floor of a semi-trailer or a lorry in order to lash down accordingly on these transported loads.

For this purpose, the attachment point has an eyelet into which a lifting, pulling or lashing means can engage in order to transmit a force. Typically, a stop point on an eyelet, wherein in the eyelet head in the manner of a chain link an additional hook eye is hooked for coupling with a stop or lashing.

To connect the attachment point of this is screwed in particular via a positive threaded engagement with the load to be lifted. However, it is also possible to couple attachment points on a load to be lifted, for example, by a cohesive connection.

In the context of the invention, the attachment point, for example, known as a rotatable transport ring, which then extends a threaded bolt of this and is guided by a bore of the load to be lifted. On the opposite side of the anchor point, the threaded bolt is countered with a nut on the load.

So that the load to be lifted can be raised as independently as possible from the receiving side, an attachment point is furthermore designed to be rotatable. Such an attachment point is for example from the DE 10 2006 052 986 A1 known. Other attachment points are through the DE 87 03 807 U1 , the DE 20 2006 006 886 U1 as well as the US 4 088 361 A known.

In a coupled train, - lifting or lashing in an abovementioned attachment point or coupled lifting, - pulling or lashing in the lifting eye may come when lifting the load in an unfavorable position of the aforementioned components to each other to a hooking or but clinging , so that the train, - lifting or lashing does not lift in the pulling direction, the load to be lifted, but can be twisted in itself.

This leads to a weakening of the train, - lifting or lashing itself, and in addition, when lifting the load and faster movements, such as a stopping movement when pivoting the load, there is the danger that by lifting the stop point lifting, - train - Or lashing untwisted in the region of the lifting eye and thus the load is abruptly lowered a few inches. On the one hand, this endangers occupational safety; on the other hand, this can cause considerable damage in the area of the material, for example due to microcracking.

It is therefore an object of the present invention, starting from the state of the art, to provide an attachment point which places itself in a correct working position independently of the pulling direction of a coupled lifting, pulling or lashing means.

The aforementioned object is achieved with an attachment point according to the features of claim 1.

Advantageous embodiments of the present invention are part of the dependent claims.

The attachment point according to the invention for coupling with a train, - lifting, - or lashing means for moving a load, wherein the attachment point has a base body which is coupled to the load to be moved, wherein an upper part is rotatably mounted in the base body and the upper part of an eyelet having, with a suspension member is coupled, is characterized in that the eyelet has a central longitudinal plane, wherein outer side edges of a rear Ösenabschnittes have a greater distance from the central longitudinal plane than side edges of a front Ösenabschnittes, each having a straight line on one side of the central longitudinal plane by both the side edge of the rear Ösenabschnittes runs, as well as through the side edge of a front Ösenabschnittes, so that the two lines intersect at an acute angle, wherein the straight lines are substantially parallel to a substrate on which the attachment point is fixed.

The attachment point according to the invention can be mounted both on a load to be lifted, for example on a container or other object or even on a lifting harness, but it can also be used on a loading floor as a lashing point.

In the context of the invention, the eyelet of the attachment point is in particular captive with a Hook eye coupled, the hook eye in particular has the shape of a chain link. In the context of the invention, however, it is also possible the eye of the attachment point directly, for example, with a hook or a shackle or the like in conjunction with a train, - lifting or lashing means to couple.

Due to the geometric design according to the invention, in particular the eyelet and most preferably the side edges, which may also be designed as side flanks or as side cheeks, it is achieved that the eyelet upon application of the impact point with a force in the pulling direction always rotates such that twisting or but verklanken the respective coupling member is prevented in the eyelet.

In the context of the invention, in particular, the hook eye is so coupled to the eye of the attachment point that the hook eye can not transversely upright when applied to the attachment point with a tensile force and thus tilted within the attachment point such that thereby the abutment point is acted upon by a torque that in turn affects a leverage on the anchor point and this could lead to premature failure of the coupling point of the attachment point with the load to be lifted. Again, when using the hook eye according to the invention by the obliquely extending side edges ensures that even with quergestellter hook eye, thus engaging a ridge of the hook eye in the eye opening when lifting the load, the attachment point rotates so that the hook eye aligned in the pulling direction and a non-twisted and also non-articulated lifting is possible.

In particular, in the context of the invention, the eyelet is captively coupled to the suspension member, wherein preferably the suspension member is formed as a hook eye. The hook eye has the shape of a chain link and is in particular made of a round steel and has two mutually parallel webs, and in each case the ends of the webs connecting arches. The hook eye is preferably carried out by forming the loop through the eyelet and coupled together in a region, wherein the coupling takes place in particular by material-locking joining. In the context of the invention, furthermore, the hook eye is preferably at least partially tempered.

The side edges are at least partially circumferentially formed in the invention at the eyelet, extending towards the eye opening and pointing away from the eyelet opening respectively curved contact surfaces extending from the side edges. In particular, the contact surfaces extending towards the eyelet opening come into positive contact when the load is lifted with the insides of the curves of the hook eyelet. In this case, the curved course of the contact surfaces may be round, in particular circular, but it may also be elliptical or may be formed with a radius varying in the direction of the central longitudinal plane.

In a further preferred embodiment of the present invention, the side edges may extend in a plane, in which case the respective straight line described above also extends on one side of the central longitudinal plane in this plane. The two planes would then intersect at an acute angle. In the context of the invention, however, it is also possible that the side edges have a convex or concave profile with respect to a plane passing through an above-mentioned straight line, in particular in a head region of the eyelet. In particular, the side edges have a curved course oriented towards the central longitudinal plane of the eyelet. Also, by this measure, in turn, ensures that in the stopper according to the invention even with a trailing hook eye when applied in the pulling direction of the train, - lifting or lashing the stop lug in the correct lifting position or lashing, therefore working position turns.

In the context of the invention, the acute angle of the two straight lines, in particular in an angular range of 8 to 45 ° and very particularly preferably from 12 ° to 20 °. In particular, the angle has a range between 12 ° and 16 °. By the above-mentioned angle, it is again ensured that, in particular, the eyelet of the attachment point turns into the correct pulling position from any imaginable position with an attachment point coupled with a pulling, lifting or lashing means. This is also done with a coupling of the lifting, -, -, or lashing with the hook eye, so that moves even with transverse hook eye the stop point in the correct lifting position.

In order to continue in the attachment point according to the invention with an eye and captive coupled to the eye hook eye a rotation of the attachment point is promoted to the correct working position, the diameter of the eye opening has a size that is 1.1 to 3 times greater than the wire diameter the hook eye, in particular, the diameter of the eyelet opening is 1.2 to 1.5 times larger than the wire diameter of the hook eye. The eyelet opening can itself be round, in particular circular, but also elliptical or with a varying radius. In the case of a non-circular diameter is in the context of the invention, in particular an arithmetic mean of the chosen, for example, resulting elliptical diameter.

The rotation of the attachment point in a working position is further preferably improved by the center of the eye having an eccentric offset with a distance to a central cross-sectional plane of the attachment point, the distance in particular having a length corresponding to between 9 and 31% of the wire diameter of the hook eye ,

The middle cross-sectional plane divides the attachment point in the middle and runs orthogonal to the central longitudinal plane.

Further preferably, the distance of the side edges is formed to the central longitudinal plane of the eyelet from a foot portion of the eyelet to a head portion decreasing. For this purpose, it is particularly advantageous if the attachment point is raised at an angle which extends between 10 and 170 ° to the surface of the object coupled to the attachment point. This, in turn, also conducive to ensure that in particular the hook eye rotates with the attachment point in the correct working position.

Further preferably, the upper part of the attachment point is for this purpose rotatably mounted on the main body via roller bearings or via a sliding bearing. In the context of the invention, for example, it is possible to insert the base body and upper part into one another and then to insert balls through an opening in the base body, so that a captive connection between the main body and the upper part is produced by means of roller bearings. Thus, the balls do not emerge from the body, this is in particular closed with a grub screw or a plug.

Further preferably, the attachment point is coupled to the base body via a threaded pin formed on the base body on a load to be moved or a loading floor, in which case in particular the base body is screwed into the object to be coupled and formed on the body turn contact surfaces, for example in the manner of a hexagon are, so that the body is firmly screwed into the object. In the context of the invention, however, it is also possible that the main body itself, for example, has an internal thread, so that it is screwed with a bolt coming from the object to be coupled with the attachment point coming from. Alternatively, a bolt is inserted into the body and then bolted to the object.

Thus, the surfaces of the attachment point, in particular the eyelets and the hook eye are particularly wear-resistant and can be used for several years with daily use, these are in particular hardened and / or tempered. Further preferably, the surfaces of eyelet and hook eye on such a property that they slide particularly well to each other, so that always a proper rotation of the attachment point is made possible in the correct working position. For example, the surfaces may be smoothed or coated. In particular, however, the surfaces and most preferably the entire components are tempered, in particular hardened.

The anchor point 1 has a basic body 2 on, being attached to the main body 2 a shell 3 affiliated, wherein the upper part 3 rotatable to the main body 2 is stored. The top 3 also has an eyelet 4 on, in turn, captive with a hook eye 5 is coupled. In the hook eye 5 For example, a hook of a lifting means can be suspended and then is a load, not shown, or an object with which the attachment point 1 is coupled, liftable by the lifting means. The anchor point 1 according to 1 is shown in a working position such that the hook eye 5 in a pulling direction Z relative to the eyelet 4 is aligned.

In practical application, however, it comes according to 2 and 3 often to a transverse hook eye 5 , The hook eye 5 itself consists of two sheets each 6 , as well as two bars 7 and has the shape of a chain link, in particular a round steel link chain link. It may be that as in 3 clearly shown a footbridge 7 at least partially within the eyelet 4 so that when lifting in the in 3 illustrated pulling direction Z it could come to a tilting, which in turn is a moment M on the main body 2 and in particular a thread extension y of the main body 2 can exercise such that it leads to premature failure of the anchor point 1 can come.

For this purpose, the invention is in 2 clearly shown, along a central longitudinal plane 9 the eyelet 4 a distance A a rear eyelet section 10 formed larger than a distance B a front Ösenabschnittes 11 , Decisive is the distance at a side edge 12 the eyelet 4 measured the outermost with the hook eye 5 part of the eyelet coming into contact with the fitting 4 represents. Becomes a straight line 13 through the distance A the rear eyelet section 10 and the distance B the front eyelet section 11 placed, with the straight line 13 runs substantially parallel to a substrate on which the anchor point 1 is set, so intersect both lines 13 at an angle Ω outside the area of the anchor point 1 ,

The angle Ω is designed in particular as a tapered angle. This will allow the attachment point 1 decisive when applying a force in the pulling direction, regardless of the current situation or position of the hook eye 5 always in the in 1 and 5 shown correct working position is pivoted and therefore not tilted, hooked or verklankt.

In the context of the invention, it is also possible that the side edges 12 in the area of the course of the eyelet 4 have a progressive or declining or convex course. In 2 one is shown to the central longitudinal axis 9 arched course over the eyelet 4 time.

Furthermore, it is shown in accordance with 4 that an eyelet opening 15 the eyelet 4 a diameter D15 which is larger in size than the diameter D5 the hook eye 5 , It has been found that it is particularly advantageous if the diameter D15 1.1 to 3 times larger, and more preferably 1.2 to 1.5 times larger than the diameter D5 the hook eye 5 ,

Further shown in FIG 2 and 4 in that it proves to be advantageous if the midpoint 16 the eyelet opening 15 an eccentric offset e to a middle cross-sectional plane 17 of the anchor point 1 having. In particular, this offset has a length which is between 9 and 31% of the diameter of the hook eye 5 has. Thus comes between the midpoint 16 the eyelet opening 15 arranged hook eye 5 an eccentric offset to the mid-section plane 17 of the anchor point 1 which, in turn, has a positive effect on panning into the correct working position.

Furthermore, the top is 3 relative to the main body 2 rotatable via roller bearings 18 stored what is in 6 is shown. Alternatively, a slide bearing can also be used here. In the cross-sectional view according to 6 It is also good to see that from the side edges 12 out in the direction of the eyelet opening 15 , as well as to the outside each have a contact surface 19 extends, with the contact surfaces 19 are curved, in particular with varying radius. This results in an inner contact surface 20 of the bow 6 the hook eye 5 when applying the anchor point 1 with a force in positive contact. This also promotes the rotation in the direction of the correct working position.

Further shown in FIG 3 that the side edges 12 also in vertical direction V at an acute angle α run inclined to each other. This preferably has an angular range between 1 ° and 40 °.

Furthermore, in 3 the central longitudinal plane 21 drawn through the attachment point running. The angle α is divided so that the left and right sides of the image plane related to the central longitudinal plane 21 each angle α / 2 results, which also supports a rotation of the attachment point in the correct working position.
