To limit the pivot range, known ortheses used for stretching have limit stop pins which can be inserted into different bores arranged around the pivot axis. A disadvantage of these, however, is that adjustment of the extension and flexion limit stop is possible only in fairly large increments, for example in 15� increments, and the pivot range limits for this reason often cannot be adjusted with sufficient precision.
The housing 12 is shown from the front in FIG. 4A and from the rear in FIG. 4B. The housing 12 has a plane middle wall 35 which is interrupted by a longitudinal slit 36 in the shape of an arc of a circle. The longitudinal slit 36 extends over about 180�. Extending upward and perpendicularly from the middle wall 35 there is a circumferential wall 38 which is interrupted by slits 37 distributed uniformly about the circumference and which thus forms individual fingers. The width of the slits 37 corresponds approximately to the width of the fingers. Moreover, protruding above the middle wall 35 there is a central sleeve portion 39 which serves as a rotation bearing for the click-stop dials 14, 15 shown in FIG. 8. Middle wall 35 and sleeve portion 39 have a central bore 40 running continuously through them.
As can be seen from FIG. 4B, a circumferential wall 41 extends above the rear face of the middle wall 35. The height of the circumferential wall 41 is higher in a first circumferential portion 42 than in a second circumferential portion 43. Situated in the first circumferential portion 42 there are several axially oriented threaded bores 44, allowing the first bar 2, which bears on the first circumferential portion 42, to be screwed tight by means of screws 45 (FIG. 3). The height of the second circumferential portion 43 is reduced compared to the first circumferential portion 42, along a circumferential length of about 200�, so as to create a corresponding free space for the first bar 2 and the push rod 8 which extend radially beyond the second circumferential portion 43. Provided in the second circumferential portion 43 there are also a plurality of radial blocking bores 46 which are spaced apart uniformly in the circumferential direction and into which the blocking pin 34 of the central rotation block 20 can be introduced, by which means the rotation position of the rotation block 20 relative to the housing 12 is blocked. The rotation position of the rotation block 20, and thus that of the coupling point 47 (FIG. 2) of the push rod 8 on the arm 26, can thus be adjusted by means of the rotation block 20, with the blocking pin 34 drawn back, first being turned to the desired rotation position, whereupon the blocking pin 34 is latched in the desired blocking bore 46. This procedure is described in more detail below.
On their outer circumference, the click-stop dials 14, 15 have a relatively fine outer toothing 50, which is shown diagrammatically in FIG. 8. Between the outer circumference and the through-opening 49, a continuous longitudinal slit 51 in the shape of an arc of a circle extends over an angle range of approximately 200�. The two click-stop dials 14, 15 are mounted in such a way that the two longitudinal slits 51 can at least for the most part be made congruent, and these in turn lie over the slit 36 of the housing 12. In this way, a limit stop pin 52 shown in FIG. 3, and which is connected fixedly to the second bar 3 via a base part 53 and screws 54, can extend upward through the longitudinal slits 36, 51 from below and move along these. Since the click-stop dials 14, 15 are blocked via the outer toothings 50 in a rotationally fixed manner relative to the housing 12 and thus relative to the first bar 2, the limit stop pin 52 can move inside the longitudinal slits 36, 51 until it has arrived at the end of the longitudinal slits 51 and either strikes against the limit stop 55 or against the opposite limit stop 56. It is thus evident that the position of the pivot range limits depends on the position of the limit stops 55, 56 relative to the housing 12 and, consequently, to the first bar 2, and that, by independent turning of the click-stop dials 14, 15 relative to the housing 12, the pivot range limits in the flexion direction and extension direction can be adjusted independently of one another.
The cover plate 19 is shown in FIG. 6. As can be seen, the top face bears the indications �Flexion adjustment�, �Stop� and �Extension adjustment�. These indications show in which direction the rotation part 18 has to be turned in order to free the click-stop dial for the flexion limit stop or the click-stop dial for the extension limit stop. In the �Stop� position, both click-stop dials 14, 15 are locked.
In order to adjust the coupling point 47 and thus the dead point of the spring force mechanism, the eccentric part 33 is displaced in the direction of the arrow 91 (FIG. 10) counter to the force of a compression spring 92 (FIG. 3) by means of turning the control knob 11 until the eccentric cylinder portion (81) lies outside the pocket 80. The eccentric part 33 can then be turned through 180� by means of the control knob 11, which is connected to the eccentric part 33 in a rotationally fixed manner via a square part 93, as a result of which the blocking pin 34 moves back into the bore 82 under the force of the compression spring 84, and the opposite end of the blocking pin 34 can emerge from the blocking bore 36. The rotation block 20 can now be rotated farther to another desired blocking bore 46, whereupon the blocking pin 34 is brought back into the locking engagement position by means of turning the eccentric part 33 back.
