Description

Künstlicher Fuß. Die Erfindung betrifft einen künstlichen Fuß mit in den Fußteil eingeordneter aufblasbarer Gummiblase. Es ist bekannt, Gummiblasen an derjenigen Stelle des künstlichen Fußes anzuordnen, die beim Auftreten den .Stoß empfängt. jedoch sind diese Blasen meist lose eingesetzt und infolgedessen sehr beansprucht. (la sie lediglich zwischen dein (-)beren und unteren Fußteile eingesetzt und eingeklemmt «erden. Die Neuheit bei der Erfindung besteht darin, (laß die Blase innerliall) einer Höhlung eines Vollgunimikörpers liegt, welcher die Forrn des Fußes hat. Durch Aufblasen der Gummiblase wird dieser Vollguntmifußkörper gleichzeitig ausgefüllt und klammert sich inf-)lgedessen mit seinen Randfalzeir in Nuten ein, die aiu unteren Rande des Fußoberteiles angeordnet sind. Es wird also durch das Aufblasen der Gummiblase innerhalb des Gummifußes nicht nur der Gummifuß in seiner Nachgiebigkeit erhöht und eine Regelungsmöglichkeit geschaffen, sondern es wird auch eine gleichzeitige Festhaltung des Fußes am Fußoberteil erreicht. Des Weiteren sind, um die Elastizität des Vollgurnmikörpers in seinem vorderen Teile j e nach Erfordernis des gegebenen Körpergewichtes zu regeln, in bekannter Weise Verstärkungsblattfedern einvulkanisiert, die zur ungefähren Hälfte in dem vorderen Teile des Gummifußes einvulkanisiert sind und mit ihren in das Innere des Oberfußes ragenden Enden unbefestigt gegen verschiedene Anschläge gelegt werden können, so daß eine größere oder geringere Spannung des Vorderfuße., einstellbar ist.Artificial foot. The invention relates to an artificial foot with Inflatable rubber bladder arranged in the foot section. It is known to have rubber bladders to be arranged at the point of the artificial foot that causes the shock when it occurs receives. however, these bubbles are mostly loosely set and, as a result, very large claimed. (Just let them be inserted between your (-) bare feet and lower parts of the foot and jammed «to earth. The novelty of the invention consists in (leave the bladder inside a cavity of a full gun body, which is the shape of the foot Has. By inflating the rubber bladder, this full guntmifoot body becomes at the same time is filled in and clings to grooves with its edge folds, the aiu lower edge of the upper part of the foot are arranged. So it becomes through that Inflate the rubber bladder inside the rubber foot not just the rubber foot in its Resilience increases and a possibility for regulation is created, but it becomes a simultaneous retention of the foot on the upper part of the foot is also achieved. Further are to the elasticity of the solid rubber body in its front parts j e after To regulate the requirement of the given body weight, reinforcement leaf springs in a known manner vulcanized, about half of it in the front part of the rubber foot are vulcanized and unsecured with their ends protruding into the interior of the upper foot can be placed against different stops, so that a larger or smaller Tension of the forefoot., Is adjustable.

Auf der "Zeichnung ist der Erlindungsgegenstand in einem Längsschnitt dargestellt. Der Fußteil ist vom Hacken bis zur Höhe des Ballens zur Aufnahme einer Gurnmiventilblase b hohl. Inmrhalb der Höhlung dieses die Fußform bildenden Vollgunrrciikörpers läßt sich die Gummiblase derart aufblähen, daß die Festklemmung der Falze c des Fußunterteiles in den N uten j des Fußoberteiles begünstigt wird. Der künstliche Fuß ist in an sich bekannter Weise mit Verstärkungsblattfedern ausgestattet. Diese Federn d sind in den vorderen Teil a des die Gummiblase b umschließenden Vollgummikörpers derart einvulkanisiert, daß die aus der Offnung r: über den Gummikörper hinausstehenden Federenden frei in den oberen hohlen Fußteil e hineinragen. In dem Fußoberteil e sind der Querrichtung des Fußes drei Anschlagstäbe h, vorgesehen, auf welchen die freien Federenden unbefzstigt anliegen, und zwar je nach der erforderlichen Spannung im Vorderfuß a auf lern Anschlag i oder 2 oder 3. Durch das am Fersenteil des htrßstückes gelegene Ventil g kann die Gurnrniblase mittels Pumpe nach Bedarf aufgeblasen werden. Der Fuß kann für jede Prothese verwendet werden.In the drawing, the subject of the invention is shown in a longitudinal section. The foot part is hollow from the heel to the height of the ball for receiving a rubber valve bladder b The artificial foot is equipped in a manner known per se with reinforcing leaf springs. These springs d are vulcanized into the front part a of the solid rubber body surrounding the rubber bladder b in such a way that the from the opening r: The spring ends protruding beyond the rubber body protrude freely into the upper hollow foot part e. In the upper foot part e, three stop rods h are provided in the transverse direction of the foot, on which the free spring ends rest without being fastened, depending on the required tension in the forefoot a on the stop i or 2 or 3. The ht The rubber bladder can be inflated as required by means of a pump. The foot can be used for any prosthesis.
