Description

Coupling device

The subject tie device of the present invention is more particularly used for connection to a rod that is used to fasten and support a container to be transported on a cargo ship, and that the coupling device is secured to the end of the rod.

Various solutions for coupling devices (locking heads) for fastening and supporting the bars of the container are known in the art. For example, European Patent Publication EP 1424277 proposes a solution with associated knotting means which is a locking head which can be fitted into different sized apertures which are placed in the corner pieces of the corners of the container. In the solution according to the publication, a locking head is fitted into a long groove at the end of the rod, and the locking head is movable in the long groove.

A notice is known from the German Patent No. DE 35 25 322, in which two fixed locking heads for holes of different sizes are assembled into the rod.

A tie rod is known from the German Patent No. DE3501109, the two ends of which comprise a locking head.

There are many weaknesses in conventional technology solutions. One weakness of the prior art solution is that when the bar is placed in a cross to secure the container, the longitudinal adjustment margin is achieved by the slotted hole of the hinge point in the locking head, so that the second rod is further from the container, and nevertheless, the rod They still collide with each other, and the holes also weaken the locking head and, on the other hand, limit the alignment of the rods.

The coupling device according to the invention is characterized by what is stated in the characterizing part of item 1 of the independent patent application.

The coupling device according to the present invention is also characterized by the items described in the second to sixth items of the patent application.

The solution according to the invention currently provided has certain significance with respect to prior art solutions. The coupling device according to the present invention is currently provided by using the solution, and the distance between the rod and the container can be adjusted to be appropriate at different angles using different locking heads (different containers), and thereby avoiding extremely poor rods colliding with each other. .

Compared to the prior art solutions, unlike the prior art mode in which the pivot pin of the support bar is free to move to a random point, in the solution according to the invention, regardless of the user and the loading state The top of the pole is optimally spaced from the corner of the container, which is connected to the corner of the container.

The solution according to the invention is also extremely durable and structurally robust, yet simple and easy to use.

In the following, reference will be made to Figures 1a-3, which are explained in more detail by means of some examples of embodiments of the invention.

Figure 1a shows a perspective view of a prior art solution in which the longitudinal adjustment margin is achieved by the elongated aperture of the hinge point in the locking head such that, as shown in the figure, the other of the rod is in the tightened state, The container is farther away.

Figure 1b correspondingly shows a side view of the solution shown in Figure 1a, and in this figure a hole (long groove) is visible, into which the rod fits so that it can move in the hole.

Figure 1c correspondingly shows a prior art solution in which the locking head is curved and has a slotted bore therein into which the rod is movably fitted.

Figure 2a shows a side view of a solution according to the invention, and shown in the coupling device 1 having at least two locking heads A, B, the locking heads comprising ends 4, 5, and the ends It also includes support surfaces 6, 7 for achieving the tightening function and the supporting function.

The end can be fitted into the hole 10, 12 (see Figure 3) at the corner of the container for fastening and supporting the container, and in this case, the support surfaces 6, 7 and the inner surface of the hole (in the figure) Can't see) contact. According to Figure 2a, the two locking heads A, B can be assembled to the rotating rod 2 (or to the end of the rod) by means of a hinge 8, so that the locking head can be rotated on the end of the rod as indicated by the arrow Select the desired angle range to select the locking head A or B to be used. Figure 2a shows the locking head A for the tightening function and the supporting function.

In the tightening condition in which the locking head A is used, the support surface 6 of the locking head A is separated from the hinge 8 by a horizontal distance A' (or, in other words, the center line of the rod drawn via the hinge, the line is indicated by a broken line) In this case, the support surface 7 of the second locking head B is separated from the same hinge 8 by a horizontal distance B', which is shown in Figure 2b.

Correspondingly, as shown in Figure 2c (2b), the locking head B is used for the fastening function and the supporting function, in which case the support surface 7 is separated from the same hinge 8 (or, in other words, with The horizontal distance is separated by the center line in the direction of the rod drawn by the hinge 8 as B'.

The support surface identified by the symbol 18 can be seen in Figure 2a, which is placed on the corner surface of the container as shown in Figure 3, and correspondingly, when the locking head B is used for fastening When supported, the corresponding support surface placed on the corner surface of the container is identified by the symbol 17 of the container.

The end pieces 4, 5 may comprise curved end faces 14, 15, but such end faces may also be flat. There may be rounded corners 20 between the ends A, B. In Fig. 2a, the surfaces at an angle to the support surfaces 18 and 17 are identified by reference numerals 16 and 19.

In the condition shown in Fig. 3, a tightening condition is shown in which the lower containers 21, 22 (including the corner pieces 21', 22', on which the containers 1 and 13 are placed) are fastened/supported by the rod 2, in which The end is a coupling device 3 according to the solution of the invention. According to the illustration, the coupling device 3 rests on the corner 隅 9' of the container 9 by the surface 18, and the locking head 5 of the coupling device is inside the hole 10, in which case the support surface 6 and the hole are shown in Fig. 2a. The inner surface (not visible in Figure 3) is in contact. Correspondingly, the locking head 4 is fitted into the bore 12 of the container 13, in which case the support surface 17 (not visible in Figure 3) shown in Figure 2a is in contact with the corner 13' of the container 13. According to the illustration, the pole position is at a different distance from the corner of the container (separate from the vertical angle 货 surface of the container), because the locking head A (see Figure 2a) is used in the container 1 and corresponds Ground, the locking head B (see Fig. 2c) is used in the container 13, and therefore, the rods do not collide with each other, because, according to the drawing, the tie rod 2 of the container 13 is closer to the corner surface of the container. / Corner of the container.

It will be apparent to those skilled in the art that the various embodiments of the invention are not limited to the examples described above and, therefore, may vary within the scope of the appended claims.

In the coupling device according to the invention, the locking heads (A, B) can be identical pieces (i.e., integrally formed as a single piece), but a solution is also envisaged in which the locking head (A) B) are different pieces (i.e., formed as separate parts), that is, in this case, they can be rotated independently of each other in an articulated manner.

There may also be three or more locking heads in each of the coupling devices.

Features that may be present in the specification in combination with other features may also be used individually, if necessary.
