Definitions

  • the invention relates to a sports device for accelerating gait, with locked natural ankle joints and without mechanical replacement joints.
  • the human gait is extraordinarily complex in its dynamic structures, its analytical examination can convey a number of insights by means of the doctrine of the dynamics of the point cluster.
  • the aim of the present invention is now to create a device which also offers more and a more comfortable mobility for pedestrians in practical use than the known devices which are unusable in practice.
  • the pedestrian should be given the feeling that his legs moved more easily, with less fatigue and less bumps, and he was able to take larger steps with a higher cadence.
  • lever gears act on both lower legs by means of fastening elements and are coupled to one another by means of ropes, springs or levers in such a way that an elastic coupling force lies below the knee joints and at least approximately in the direction of the walking direction, the leg left in the direction from behind accelerated downwards to the top or only to the front, and also the projecting leg forward to the bottom or only to the front hesitates.
  • the invention is based on a number of observations which can be made in the plane in the course of a normal gait cycle.
  • the hip must be lowered before and during the heel touchdown.
  • the center of gravity of the body is also lowered and potential energy is converted, this replacement taking place in the stabilizing muscles of the hip or trunk.
  • This potential energy is converted into heat in the muscles, so it is lost for the movement process, but at the same time these muscles also consume metabolic energy, which is also lost.
  • the same loss principle runs through several sections of the entire walking process. While the foot is put on until it lies flat on the floor, it is loaded with increasing force up to the body weight and prepared for the subsequent support phase. He turns in the upper ankle in the so-called plantar flexion under increasing load.
  • gravity is implemented as work in a way, the force having to be in balance with that of the supporting muscles and being converted into heat in these muscles with simultaneous metabolic losses.
  • This is followed by a movement area that consumes little energy, while the body's center of gravity moves approximately circularly around the ankle joint in the sense of dorsiflexion.
  • Force measurements in human gait have shown that during this phase the supporting force in the leg is less than the body weight.
  • This is followed by the initiation of the living walking force in the sense of active plantar flexion, which is essentially fed by the calf muscles.
  • the heel is already raised again and the ball of the foot exerts a force on the floor that is greater than the body weight and raises the center of gravity back to the original height.
  • the principle of loss of the human gait in the plane is to convert potential and kinetic energy in muscles into heat, which means that it is lost for dynamic movement, and these muscles also have to strain the metabolism for their performance.
  • Fig.l schematically represents an embodiment of the invention and Fig.2 shows on an enlarged scale a hydraulic device according to the invention; 3 shows a further embodiment of the invention with schematically indicated switching means in a representation similar to FIG. 1.
  • a shoe or boot-like support shell 1 serving as a holding device or fastening element is connected by means of the straps 2 to the lower leg and foot of the user. As a result, it transmits the axial forces via its lower part and immobilizes the ankle joint.
  • the support bracket 3 of the step means is guided in an axially movable manner via guides 4, the step surface 3 1 of the step bracket 3 being designed in the form of a circular arc for the purpose of rolling the entire body in the embodiment shown.
  • both legs are coupled to one another via a lever mechanism, which consists of coupling rods 6 and a spring 7.
  • the step length is a measure of the respective spring tension.
  • FIG. 2 shows, for example, a hydropneumatic energy storage system in which a gas is compressed in space 9 in a cylinder 10 which is firmly connected to the support shell 1.
  • a piston 11 is fixedly connected to the support bracket 3 via a piston rod 15 and absorbs its axial forces, which it transmits to the gas 9 via a liquid seal. Below the piston 11 there is a barrier liquid in the space 13, the leakage from the check valve 14 is prevented. As a result, the piston 11 is held in any prestressed position.
  • a number of other switching functions are known in hydropneumatics, which can be used expediently here, e.g. to be able to carry out the holding function in the case of different compression processes of the gas.
  • the piston rod 15 is designed as a tube which is connected on the one hand to the space 13 via the bore 12, on the other hand it is closed off by the switching means designed as a valve 5. B i opening the valve 5 by contact with the ground, the barrier liquid flows from the space 13 via the valve 5 into the interior of the support beam 3, which is connected via an opening 17 to an elastic sealing and expansion vessel 16.
  • a special effect can be achieved if the piston 11 is not designed as a single piston but as part of a differential piston system. Then the energy is dissipated through it over a larger piston area, whereby a greater restoring force is generated with a smaller stroke.
  • the coupling rod 6 is pivotally mounted in the bearing 8 by a limited angle and is coupled to the other leg by a pivotable spring 7 at the other end.
  • Cable pulls can also advantageously be used here, the springs then being able to be located in the interior of the rods 6.
  • the direction of the spring force can be changed by selecting the limit.
  • the spring force can also be used to move the step means 3 upwards, so that a shorter length is present when the leg is subsequently moved forward. Such a shorter length can, however, also be achieved by other means.
  • the tread surface 3 1 is curved. This curvature should be such that the path of the body's center of gravity is at least approximately straight during the support phase. This is achieved when the radius of curvature corresponds to 0.3 to 0.7 times the height of the user.
  • the two coupling rods 6 'forming part of the lever mechanism are connected via two pivotably connected levers 20, the movement of which is limited by a rope 21.
  • the coupling rods 6 1 are designed telescopically and springs 22 engage the extendable parts 6 ′′. If the telescopic mobility is designed in such a way that the extendable parts 6 "can move freely over a fixed distance before the springs 22 engage, the coupling rods can be connected directly by means of a ball and socket joint.
  • FIG. 3 shows that the switching pulse takes place
  • the valve 5 can be removed from the knee joint function via a linkage 23.

Abstract

Dans un appareil d'entraînement pour l'accélération de la marche, avec des articulations de cheville naturelles bloquées et sans articulations de remplacement mécaniques, des mécanismes à levier (6) agissent au moyen d'éléments de fixation (1) sur les deux jambes et sont couplés entre eux au moyen de câbles, ressorts ou leviers (7) de telle manière qu'une force de couplage élastique accélère, au-dessous des articulations du genou, et approximativement dans le plan du sens de la marche, la jambe restée en arrière dans le sens arrière-bas vers l'avant-haut, ou seulement vers l'avant, en ralentissant en même temps la jambe lancée vers l'avant-bas ou seulement vers l'avant.
