Definitions

  • the invention relates to a resilient running and jumping shoe with an upper and a lower sole, which are elastically connected.
  • Trampoline-like jumping sports can be used.
  • Springy running and jumping shoes are known in many embodiments.
  • Various types of springs are used, such as coiled compression springs, tension springs, leaf springs, rubber and foam rubber pads and pneumatic springs.
  • tension springs With a spring travel of several centimeters, the exact guidance of the lower sole, which touches the ground when walking, is a problem.
  • Complex devices are described to ensure that a breakaway to the side or to the front and back is prevented. The guide problem is solved when using wide leaf springs or similar components.
  • the DGM 7701451 describes an embodiment which contains a leaf spring, the front half of which is designed as an outsole and the rear end of which is attached to the rear end of the upper sole.
  • Embodiments also have the disadvantage that only part of the leaf spring can fully develop its spring action because it is partially designed as an outsole.
  • a spring calculation shows that you can quickly exceed the permissible strength values of spring steel if you want to absorb forces with current springs that correspond to a multiple of your body weight.
  • a springy running and jumping shoe contains two spring effects, namely one which absorbs the downward thrust when the heel is put on and converts it into an upward and forward thrust in the course of the fun rolling, and a second that improves the bounce with the toe.
  • a complex device for converting the heel thrust into a forward thrust is described in DOS 3012945. Simpler designs with two springs are described in DE 3017769A1 and in DE 3034126A1.
  • the latter publication also contains an embodiment with two S-shaped leaf springs, one of which is fastened to the front and one to the rear end of the shoe. The two loose ends of the leaf springs form the outsole. At least one of the two springs must be divided into two for reasons of symmetry.
  • the object of the invention is to develop a resilient running and jumping shoe with a spring action in the heel area and a second in the forefoot area with good forward, backward and lateral stability, which resiliently absorbs forces which correspond to a multiple of the body weight with a spring travel of several centimeters.
  • the object is achieved in that the elastic connection between the upper and lower sole of a resilient running and jumping shoe contains a leaf spring of approximately shoe width, one end of which at the front or rear part the upper sole and the other end is attached to the opposite part of the lower sole.
  • the running process with shoes according to the invention is considered.
  • the leaf spring which is flat in the unloaded state, curves in one direction, when it is pushed off with the tip of the foot in the other (FIGS. 2 and 4).
  • the foot executes a rolling movement which is supported by the now S-shaped spring, whereby the curvature caused by the heel pressure and later the curvature caused by the forefoot predominates.
  • the energy stored in the leaf spring by placing the heel is converted into an upward and forward thrust during the rolling process.
  • the springy running and jumping shoes according to the invention significantly improve the efficiency of the running process, easier and faster running and higher and further jumping is possible.
  • the use of leaf springs which take advantage of the full width of the shoe or a little more, provides good forward, backward and lateral stability even with spring travel of several centimeters. It takes only a little practice to achieve safe running and jumping with the shoes according to the invention.
  • An advantage over the prior art is the use of the spring action of leaf springs in two directions instead of the use of two springs. As a result, the spring weight and the required spring space are halved with the same spring action and the same material stress.
  • FIG. 1 The basic structure of a resilient running and jumping shoe according to the invention is outlined in FIG.
  • An essentially rigid upper sole 1 forms the shoe sole of a sports shoe 2 encompassing the foot.
  • ground contact has only an essentially rigid lower sole 3, which is connected to the upper sole 1 via a wide leaf spring 4.
  • the one end of the leaf spring 4 is connected to the front part of the upper sole 1 and the other end of the leaf spring 4 to the rear part of the lower sole 3.
  • the lower sole 3 contains a tread 5, a profiled sole 5, rubber studs, spikes or similar devices for improving the grip on the ground where it touches the ground when running.
  • the width of the leaf spring 4 corresponds to the shoe width, but can also be somewhat larger or smaller.
  • Figure 2 shows how the leaf spring 4 bends when the heel is loaded. With a uniform vertical foot load, the spring 4 bends in an S-shape, as outlined in FIG. 3.
  • Figure 4 shows the conditions when the toe is loaded.
  • the two soles 1 and 3 do not have to be parallel to one another in the unloaded state. By a slight upward adjustment of the upper sole 1, the jump performance can be achieved at the expense of Increase heel thrust, the reverse applies when downward.
  • the leaf spring 4 can in the unloaded state just as shown in Figure 1, or can be curved in an arc or S-shape. The curvature can influence the ratio of heel push to toe push even with parallel soles 1 and 3.
  • the two soles 1 and 3 or one of the two can also be elastic. If, for example, the lower sole 3 is designed as a leaf spring, it will bend towards the leaf spring 4 when the toe is loaded in accordance with FIG. 4. In the case of heel loading, an elastic lower sole 3 has no influence if one starts from a running and jumping shoe according to FIG. 1. The situation is reversed if, as described above, the leaf spring 4 is attached the other way round.
  • the load on the leaf spring 4 in a running and jumping shoe according to example 1 according to the invention is greatest just behind the attachment to the soles 1 and 3.
  • the spring curvature is strongest just behind the attachment to the upper sole 1.
  • the situation can be improved a little by conically designing the springs in terms of thickness or width, the thinnest point then being in the middle between the two fastenings.
  • Such springs are difficult to manufacture and therefore expensive.
  • the leaf springs 4 can be optimally dimensioned in terms of size and weight if support is provided to ensure that a maximum spring curvature specified by the material properties cannot be exceeded.
  • FIG. 1 Such a running and jumping shoe according to the invention is sketched in FIG.
  • the upper sole 1 and the lower sole 3 are formed in an arc shape with their side facing the leaf spring 4, so that the leaf spring 4 can lean against the soles under load.
  • a flat leaf spring 4 made of high-quality hardened spring steel (55 Si 7) 5 mm thick, 90 mm wide and an effective length of 260 mm, a tensile strength of 1200 N / mm is not exceeded when the arcuate sole parts are formed by circular path sections with a radius of 435 mm. These dimensions correspond approximately to the ratios of FIG. 5.
  • a 75 kg athlete equipped with such shoes compresses the springs 4 by approximately 11 mm when both shoes are standing evenly, when a shoe is loaded with the heel or toe with 300 N, that is four times body weight, about 69 mm. At about ten times the body weight, the maximum possible spring travel of 75 mm is reached. These values are favorable for a normal endurance run, the springs have to be reinforced for fast short distance runs and the spring travel has to be increased for long and high jumps.
  • the soles 1 and 3 are not curved in their full width. It is sufficient if the leaf spring 4 can lean against an arched rib on both sides of the shoe.
  • the soles are e.g. Manufactured as an aluminum casting and, in addition to the arched ribs, contain struts and receptacles that promote stability, for fastening the leaf spring 4 and the sports shoe 2 surrounding the foot.
  • the running and jumping shoes according to the invention described in this example have the advantage of greater safety against tipping over those described in example 1.
  • the possibility of twisting the leaf springs, which must be avoided by appropriate foot posture, is greatly reduced by leaning against the arched ribs.
  • curved leaf springs 4 can also be used. The curvature of the soles must then be adjusted accordingly and flat or even negatively curved soles may be required to ensure that the leaf springs are leaned against the permissible tension.
  • the leaf springs 4 can, however, also be constructed in several stages, as it is e.g. is common with vehicle springs. Additional springs of a different type can also be used. It is advantageous e.g. the use of a pneumatic spring 6 in the front and in the rear shoe part, as is shown in Figure 6. If the pneumatic springs 6 are inflatable with the aid of a valve 7, the spring force can be adapted to the intended stress by different filling.
  • FIG. 7 shows an embodiment of a running and jumping shoe according to the invention, in which only the front part of the sports shoe 2 comprising the foot is firmly connected to the sole 1. To make this clear, FIG. 7 shows the shoe when the tip of the foot is loaded as in FIG. 4. The rear shoe part is lifted off the upper sole 1 and the toe joint is bent. The jumping behavior is improved compared to Examples 1 to 3 and corresponds to running with normal sports shoes.
  • the rear part of the shoe touches the upper sole-1, the lifting only begins when the toe is pushed forward. Similar conditions can be found in cross-country skiing, all the devices and measures known there can be adopted here. It is therefore expedient to attach a toe-forming pad 8 in the heel area on the side of the upper sole 1 facing the shoe 2, which ensures good adhesion between the shoe sole and the upper sole 1.
  • the front shoe can also be connected to the leaf spring 4 via a swivel joint which is located in the area of the toe joint or at the tip of the foot.
  • a sensible addition is protection against the contamination of the leaf springs 4 and the arcuate guide ribs.
  • This protection can e.g. can be achieved by a rubber sleeve that connects the edges of the two soles 1 and 3 together.
  • High-quality hardened spring steel is preferred as the material for the leaf springs, but spring bronzes, fiber-reinforced plastics or other spring materials can also be used.
  • the flat leaf spring shape with uniform thickness and width is preferred because it is the cheapest. But there are also other leaf spring shapes, e.g. arcuate or S-shaped curved question. Multiple springs have advantages at high loads.
  • the width of the springs 4 corresponds approximately to the width of the shoe, the length is usually slightly above the length of the shoe. To absorb larger forces, wider springs 4 are useful, longer springs 4 can be realized with longer springs 4. Longer spring travel can also be achieved in that several of the described inventive anchorings are mounted one above the other, so that the running and jumping shoe according to the invention contains two or more leaf springs 4 and one or more midsoles, which can also be reduced to fastening elements which cover the ends of Connect two leaf springs together.
