Description

The present invention relates to a connecting device for connecting stop means and / or lashing means according to the features in the preamble of claim 1.

Lashing points for coupling with stop means and / or lashing means, in particular on pallets, containers or frames to be lifted are known from the prior art. For example, is from the DE 100 138 45 A1 a device is known in which a Verbindungselernent is mounted in sliding contact on a socket, wherein the socket consists of two parts, the mutually facing end faces abut against each other. The plain bearing meets in most cases the requirements to be met.

Such known, flat lashing points have the advantages that they have a high level of security against breakage in all directions of load, at the same time very flat design. They can be rotated 360 degrees and the eyelet can be swiveled through 180 degrees.

The known from the prior art flat lashing points are made such that a sleeve is enclosed in a hanger body by forming the hanger body and pivotally mounted. Subsequently, the lashing points are coupled with a screw at its attachment point to be fastened.

A disadvantage of the flat lashing points known from the prior art is that sometimes the individual component components can not be hardened separately from one another by different hardening treatment methods, since they produce one unit after assembly.

From the US Pat. No. 6,068,310 a lashing point is known, which has a hanger body, wherein in a hanger body, a packing is arranged and between the hanger body and the filler body, a pivotable eyelet is arranged. The eyelet is pivotable about a pivot axis, but can not be locked, which is why it is only suboptimal in the application for the respective operator, since it must be held for coupling by hand.

From the EP 1 840 070 A2 as well as from the AT 412 269 B Lashing points are known in which an eyelet is pivotally mounted in a hanger body, wherein for locking the eyelet it is clamped by means of a bow spring within the hanger body. In this case, no bearing bushes are arranged between the stirrup body and a bolt fastening the stirrup body, which is why handling, for example, a turning of the lashing point about the axis of the bolt, is made more difficult. Also, an assembly of provided with the bow spring eyelet and the hanger body is complicated.

Object of the present invention is therefore starting from the prior art to optimize a connection device in their weight and hardness and at the same time to make maintenance friendly and easy to install.

The aforementioned object is achieved with the features of claim 1.

Advantageous developments are the subject of the dependent claims.

The connecting device according to the invention for connecting stop means and / or lashing means has a hanger body and an eyelet. The eyelet is pivotally mounted on the bracket body about a pivot axis and the bracket body is rotatably coupled to a bolt at an attachment point about an axis of rotation. In the hanger body two bushings are used, via which the hanger body is rotatably mounted about the axis of rotation. The pivot axis of the eyelet and the axis of rotation of the hanger body are arranged at an angle to each other, which is preferably 90 degrees. The axis of rotation and the pivot axis are arranged at a distance from one another.

According to the invention, the hanger body is U-shaped in its cross-section. In the hanger body itself, a packing is arranged, wherein between the packing and the in the valley region of the U-shaped configured hanger body, a storage area for the eyelet is formed. The filler is according to the invention removably arranged in the hanger body, so that by removing the filler body, the eyelet from the hanger body is also removed.

The advantage of the invention results from the fact that all component components can be manufactured individually and processed in such a way that they are optimally designed in terms of load technology. Specifically, this means that both the stirrup body and the filler body and the eyelet can be manufactured individually and also cured individually by, for example, a heat treatment and thus each have a specific hardness, tensile strength and tensile strength, which are not influenced by individual production steps of the assembled component ,

Likewise, the production and also the production of the individual components are easy to implement, especially under technological aspects and thus offers enormous cost-saving potential in the production of the attachment point according to the invention.

The connecting devices according to the invention can also be used in the form of lashing points on troughs of truck beds, ship loading areas or the like.

Between the filler and the eye two resilient clamping means are arranged at a distance from one another, with which the pivotable eyelet can be locked in a respective position. The spring-elastic clamping means is, for example, a spring, preferably a helical spring. The elastic tensioning means are arranged between the filling body and the eyelet such that a pressure force is exerted by the filling body on the tensioning means on the eyelet. The eyelet is thus pressed in the valley of the U-shaped configured packing from the inside to the valley area and / or to the storage area. As a result, a friction force between the eyelet and the bearing area, so that the eyelet remains in a respective pivoted position. This provides in the context of the invention, the possibility that the eyelet for the user mechanic is pivotable in a working position and then a stop means, such as a chain, can be suspended.

If the attachment point is not used, the eyelet can be folded down, so that it does not occupy a storage space or working space as a flat attachment point. The resilient tensioning means is preferably arranged in a blind hole in the filling body. This in turn also results in the advantage that the assembly of the connecting device according to the invention is particularly easy. The spring-elastic clamping device is exposed during operation to increased wear or increased stress. Due to the simple disassembly and assembly of the connecting device according to the invention, it is particularly easy to replace by the clamping means. Also, the clamping means may be specially processed in the invention at its ends. For example, it may be flattened or else a protuberance in the form of a sleeve or a rivet have, so that in turn the wear resistance of the clamping means and also the fixability of the eyelet are optimized.

Preferably, the two resilient clamping means are arranged such that they are each arranged at a 90 degree angle to the pivot axis of the eyelet parallel to a distance next to each other. This offers in particular the advantage that the eyelet can not tilt in the storage area or not schlackert. It is therefore always very precisely kept pivotable in the respective working position.

Another advantage is that the filler can not move or twist within the hanger body by the two clamping means.

The filler is particularly advantageously dimensioned such that it rests on the legs of the U-shape of the hanger body at least partially flat. Due to the positive engagement of the filler body gives the hanger body increased rigidity and a snug fit, especially with regard to the attachment to the bolt and on the storage area. In the context of the invention, the filler body is in its thickness, this means the area between the two legs of the U-shaped configured hanger body, always formed at least minimally larger than the diameter of the eyelet in the storage area.

Preferably, the filler is penetrated by the bearing bushes and the bearing bushes and the two clamping means keep the filler fixed in its relative position to the mounting body. As a result, a positive and firm hold of the entire connection device is given by a positive connection. Thus, it is not necessary to produce the assembly of the connection device according to the invention by driving in eyelet or packing with complicated mechanical coupling methods or else by means of a further joining method, for example welding or even gluing or else a forming method. By particularly easy assembly and vice versa by simple disassembly, is the Connection device according to the invention thus complete particularly maintenance and easy to use.

This also results in the advantage that the filler can be removed by removing the bearing bush from the mounting body. In the case of wear or, for example, a wear test of the hanger body, it is thus possible to check by removing the filler body the hanger body.

By removing the filling body from the hanger body, it is thus also possible to remove the eyelet from the hanger body. In the case of a damaged eye or a torn eyelet or even a worn eyelet, it is thus possible to change the eyelet individually by experts. It is thus possible, especially under maintenance-friendly aspects, to renew the connecting devices according to the invention by general overhauls. Thus, it is not necessary to repeat all complex process steps for producing a complete connecting device, but, for example, the use of the connecting device according to the invention is in turn only generated by replacing a worn eyelet.

In a further preferred embodiment variant, the filler has a bearing side on its side oriented toward the eyelet. This is, for example, a likewise U-shaped configuration to understand. That is, the bearing side is formed such that it has a radius which substantially corresponds to the radius of the eyelet in the storage area. In the case of handling the lashing points is thus ensured even under load that the eyelet always remains pivotally mounted in the storage area, in particular on the bearing side of the packing.

In a further advantageous embodiment, a spring washer is incorporated between the bearing bushes. The spring washer engages when screwing a bolt for fastening the receiving device to, for example, a mounting location on a container o. Ä. In the External thread of the bolt. This ensures that the bearing shells can not fall out of the bolt. Also, the spring washer always exerts such a force on the bolt, so that an unwanted loosening of the connection device is avoided.

In another embodiment, the bearing bushes are pressed together in the bracket body. They thus pass through the arranged in the ironing body filler and are pressed together so that none of the components can be solved. At the same time, the two bearing bushes are pressed together in such a way that the hanger body and also the filler body can rotate about the bearing bushes.

In a further preferred embodiment, at least one bearing bush is formed with an internal thread. This results in the possibility that in the internal thread, the external thread of the bolt is screwed. After mounting the connection device, it is thus possible to additionally secure by countermoving the bearing bush with the internal thread. The bearing bush with the internal thread thus assumes a safety function of the bolt with simultaneous storage function for the hanger body and the packing. Particularly preferably, the bearing bush with the internal thread is designed such that it is adjustable via positive tool engagement, for example via an external hexagon.

In a further preferred embodiment of the present invention, a circumferential groove is formed in the opening of the filling body. The groove itself may be bounded on its flanks by the filler body or else on one side by the filler body and on the other side by the ironing body. Furthermore, at least one bearing bush preferably has an outer shoulder. When assembling the connecting device according to the invention this paragraph is at least partially engaged with the previously described groove. The at least partially engagement results from the action of the spring-elastic clamping means. It is thus a tilting of the bearing bushes in the hanger body, so that these only by manual or mechanical action from the Ironing body can be removed and therefore do not fall out during assembly, storage or transport from the hanger body.

Also particularly advantageous may additionally be an insert in the U-shaped valley region of the hanger body. This insert can be formed for example from an insert in the form of a Teflon bearing bush or other metal or plastic-like bearing bush. Again, there is the particular advantage that even under load, the eye is basically pivotally mounted.

In a preferred embodiment of the present invention, the distance (a) between the axis of rotation and the pivot axis preferably corresponds to 0.25 to 4 times the diameter of the bolt provided for fastening the connecting device. In particular, the distance (a) corresponds to 0.5 to 2.5 times and more preferably 1 to 2 times. Especially under aspects of production technology, this results in an optimal distance between pivoting and operability of the connecting device according to the invention by utilizing an optimal lever arm ratio produced by the distance (a).

Furthermore, the distance (b) corresponds to 0.5 to 2.5 times, in particular 1 to 2 times the diameter of the bolt required for fastening the attachment point according to the invention. This always results in an optimal distance proportioning of the two resilient clamping means, taking into account the bolt used in each case.
