Abstract

The foot (2) has a damper unit (1) controlling a dorsal movement relative to ground, where the foot is connected with a joint frame (4) over a foot axle (3) such that a controlled dorsal extension and inflection is enabled. A lateral displacement is carried-out in the joint frame about 6-9 mm for right and left legs. A lower damper retainer (7) is articulately connected with the axle of the joint frame over an adjustable rocker (8). A rear damper eye is adjusted over rubber buffers or carbon leaf (9). An independent claim is also included for a prosthesis.

Description

Nachfolgend wird die Prothese wie folgt beschrieben:

  • 2. Das Einachs-Knöchel-Gelenkfuß nach Anspruch 1 bis 7 bildet eine Knöchel-Gelenkeinheit und dient zum gelenkigen Verbinden des Fußes mit den weiteren Modulen der Beinprothese
  • 3. Die Einachs-Technologie des Gelenkfußes nach Anspruch 1 bis 7 ermöglicht die gesteuerte Dorsal-Extension bis zu 10° aus der Ruhestellung, wenn der Fuß aufrecht zum Boden steht und Flexion bis zu 20° um die Haupt-Achse.
  • 4. Die Steuerung des Fußteils (2) kann durch Gummipuffer, Rotationsdämpfer oder elektronisch aktuiert werden. 2
  • 5. Der Gelenkfuß in Verbindung mit Fußunterteil mit drei Blätter im Vorfußbereich ermöglicht
  • a. flexible Abrollbewegung
  • b. Anpassung an Bodenunebenheiten
  • 6. Die Gelenkgabel (4) bildet stilistisch die Form des physiologischen Unterschenkels ab. 3
  • 7. Der Gelenkrahmen (4) ermöglicht einen Seitenversatz zw. 5 u. 9 mm rechte u. linke Seiten 3
  • 8. Der Dämpfer (1) für die Prothese kann optional eingebaut werden. Mögliche Ausführungen des Dämpfers:
  • a. Karbonblatt
  • b. Gasdämpfer (1)
  • c. Elektrofluiddämpfer
The prosthesis is described below as follows:
  • 1. The single-axis ankle joint foot according to claim 1 to 7 is suitable for exoskeletäre application for loss of the lower limb
  • 2. The single-axis ankle joint foot according to claim 1 to 7 forms an ankle joint unit and serves for articulated connection of the foot with the other modules of the prosthetic leg
  • 3. The Einachs-technology of the joint foot according to claim 1 to 7 allows the controlled dorsal extension up to 10 ° from the rest position when the foot is upright to the ground and flexion up to 20 ° about the main axis.
  • 4. The control of the foot part ( 2 ) can be actuated by rubber buffers, rotary dampers or electronically. 2
  • 5. The articulated foot in conjunction with foot base with three leaves in the forefoot area allows
  • a. flexible rolling movement
  • b. Adaptation to uneven floors
  • 6. The yoke ( 4 ) stylistically depicts the shape of the physiological lower leg. 3
  • 7. The hinged frame ( 4 ) allows a page offset between 5 u. 9 mm right and left left sides 3
  • 8. The damper ( 1 ) for the prosthesis can optionally be installed. Possible versions of the damper:
  • a. carbon leaf
  • b. Gas damper ( 1 )
