Description

Künstlicher Fuß mit Hacken- und Zehenfederung. . Gegenstand der vorliegenden Erfindung bildiet ein. -künstlicher Fuß, bei dem mittels eines Federgehäuses eine ruhige, vom normalen Gang nur wenig unterscheidbare Gangart ermöglicht werden soll.Artificial foot with heel and toe suspension. . Subject of the present Invention imagines one. -Artificial foot, in which by means of a spring housing a quiet gait, which is only slightly distinguishable from normal gait, is to be made possible.

Die Zeichnung stellt ein Ausführungsbeispiel des künstlichen Fußes dar, und; zwar zeigt: Fig. i einen Längsschnitt durch dein. Fuß, Fig. z einen Schnitt diurch die Mitte des Fußgelenkes, Fig. 3 einen Querschnitt durch den Fuß. Der Fuß besteht aus einem oben öffenen Gehäuse a, welches unter dem Einfluß an sich bekannter-Knöchelgelenkfedern e steht und an dessen Boden am Heckenende .eine den Rufstoß der Ferse dämpfende Fersenfeder d und nach vorn hin eine Blattfeder b mit einem die Zehen umgreifenden Federhaken c angebracht ist. Das Gehäuse a ist durch Gelenkbolzen mit dem unteren Holzteil f des Unterschenkels verbunden. Der mittlere Teil des Holzteiles f, in Form einer ovalen Scheibe, dient als Auflagefläche der zwei Gelenkfedern e und von oben her als Auflagefläche der großen Federg (zu.rAbfederung desKörpergewichts). Der obere Schaft des Holzte=iles f dient in seinem zylindrischen Teil zur Führung der großen Feder g, in seinem prismatischen Teil zur Führung des Druckstückes i. An dieses Druckstück i wird das künstliche Bein befestigt. Zur Begrenzung des Druckstückes nach: oben dient eine Scheibe, die an dem pris- matischen Teil des oberen Schaftes des Holztei;les f angeschraubt ist. Filzpolsterung und Lederbezug geben dem Fuß seine natürliche, einem gesunden Fuß entsprechende Form.The drawing shows an embodiment of the artificial foot, and; although: Fig. i shows a longitudinal section through your. Foot, Fig. Z shows a section through the middle of the ankle, Fig. 3 shows a cross section through the foot. The foot consists of a housing a open at the top, which is under the influence of well-known ankle joint springs e and at the bottom of the hedge at the end of the hedge .a heel spring d that dampens the shout of the heel and a leaf spring b with a spring hook c that encompasses the toes towards the front is appropriate. The housing a is connected to the lower wooden part f of the lower leg by means of hinge pins. The middle part of the wooden part f, in the form of an oval disc, serves as a support surface for the two articulated springs e and, from above, as a support surface for the large Federg (for cushioning of the body weight). The upper shaft of the wooden part f is used in its cylindrical part to guide the large spring g, and in its prismatic part to guide the pressure piece i. The artificial leg is attached to this pressure piece i. To limit the pressure piece towards the top, a washer is used which is screwed to the prismatic part of the upper shaft of the wooden part f. Felt padding and leather cover give the foot its natural shape, corresponding to a healthy foot.
