18. The joint according to claim 11, wherein the at least one spacer element comprises a plastic material.

Description

[0018] An embodiment of the present invention will be described in more detail below by means of the accompanying drawings, in which:

[0019] FIG. 1 is a schematic view of a joint according to a first embodiment of the present invention,

[0020] FIG. 2 is a sectional view of the joint from FIG. 1,

[0021] FIG. 3 is a schematic three-dimensional view of an enlarged portion of the joint from FIGS. 1 and 2,

[0022] FIG. 4 shows the joint from FIGS. 1 to 3 in a partly disassembled state, and

[0023] FIG. 5 shows a spacer element according to an embodiment of the present invention in three different views.

[0024] FIG. 1 shows a joint 1 according to a first embodiment of the present invention. Said joint has a first articulated arm 2 and a second articulated arm 4, which are interconnected so as to be pivotable about a pivot axis 6. The first articulated arm 2 has a receiving device 8, on which a further component, for example a rail for an orthopedic device, can be arranged.

[0025] The first articulated arm 2 also has a recess 10 into which the second articulated arm 4 protrudes. By means of the connecting element 12 guided through the two articulated arms 2, 4, the articulated arms 2 and 4 are interconnected.

[0026] In FIG. 1, within the recess 10, a spacer element 14 can be seen between the first articulated arm 2, i.e. the upper wall of the recess 10, and the second articulated arm 4. Said element protrudes out of the recess 10 by means of a stop 16.

[0027] In addition, two receiving bushes 18 are arranged on the first articulated arm 2, into which bushes it is possible to insert a for example resilient stop element which defines the pivot angle about which the second articulated arm 4 is pivotable relative to the first articulated arm 2. By means of adjustment devices 20, the toughness of a stop of this kind can be adjusted.

[0028] FIG. 2 is a sectional view of the joint 1. The first articulated arm 2 and the second articulated arm 4 can be seen, as well as the connecting element 12 guided through the two articulated arms 2, 4. From the left-hand side of the first articulated arm 2 in FIG. 2, a counterpart-connecting element 22 is inserted into the holes provided for that purpose and is screwed to the connecting element 12. This ensures the two articulated arms 2, 4 are fastened to one another. On both sides of the second articulated arm 4 within the recess 10, there is a spacer element 14, said elements abutting an edge of the recess 10 by means of the respective stops 16.

[0029] FIG. 3 is an enlarged illustration in a schematic three-dimensional view. In this figure, the recess 10 into which the second articulated arm 4 is pushed can be clearly seen. It is also possible to see the stop 16 on the connecting element 12, which is also pushed into the recess 10. Said element is located between the first articulated arm 2 and the second articulated arm 4. This means that the second articulated arm 4 is located on one side of the connecting element 12 and at least a part of the first articulated arm 2, in this case specifically an upper wall 24 of the recess 10, is located on the other side. Similarly, on the opposite side of the second articulated arm 4, a lower wall of the recess 10, also belonging to the first articulated arm 2, can of course be located on the side of the spacer element 14 opposite the second articulated arm 4.

[0030] FIG. 3 shows that the connecting element 12 is equipped with a positive-fit element 26, by means of which said element can be operated and handled using a tool.

[0031] FIG. 4 shows the joint 1 in a partly disassembled state. The first articulated arm 2 has a recess 10 into which the second articulated arm 4 is pushed. However, the two spacer elements 14 are not inserted into the recess 10. It can be seen that they have a hole 28 through which the connecting element 12 and, in the embodiment shown, also the counterpart-connecting element 22 can be guided. The counterpart-connecting element 22 has an internal thread designed to correspond to an external thread of the connecting element 12. The positive-fit element 26 is shown again in the connecting element 12.

[0032] The two spacer elements 14 again have the stops 16, which, in the embodiment shown, form an angle with the main surface 30 of each spacer element 14, said angle being 90 in the present case. The stop 16 is formed such that it abuts an edge 32 of the recess 10 when, as shown in FIGS. 1, 2 and 3, the spacer element 14 is pushed into the recess 10 and the connecting element 12 and the counterpart-connecting element 22 are guided through the hole 28. It goes without saying that, for example, a nut for a screw or a similar element is possible instead of a counterpart-connecting element.

[0033] It can be seen in FIG. 4 that the first articulated arm 2 and the second articulated arm 4 each comprise a hole 28, which have to be overlapped in order to assemble the joint 1. Only then can the connecting element 12 be guided through the holes 28 in the first articulated arm 2, the second articulated arm 4 and all the spacer elements 14 provided.

[0034] FIG. 5 shows the spacer element 14 in three different views. It can be seen in each view that the spacer element 14 comprises a main surface 30 in which the hole 28 is arranged. The spacer element 14 further has the stop 16, which bulges out slightly in order to follow the edge 32 of the recess 10. Of course, other geometries are also possible in this case.
