Definitions

  • the present invention relates to a jumping shoe for facilitating the movement of people on their own. This is made possible by a system of energy storage devices that can be detachably attached to both legs of the person.
  • a jumping shoe is a device with energy storage devices (e.g. springs, magnets, compressed air) which, through compression and deflection of at least one energy storage device, enable the person using this system to jump, step-by-step movement on the ground. It is used for faster locomotion and for jumping.
  • energy storage devices e.g. springs, magnets, compressed air
  • Such jumping and bouncing devices have been known for a long time and are characterized by a wide variety of spring arrangements. They should enable locomotion with jumps, similar to those on a trampoline.
  • jumping device DE 199 34 014 A1 J Scripture, for example, is such a jumping device DE 199 34 014 A1 refer to.
  • This jumping device is distinguished in a special way in that the spring element is designed as a leaf spring which has an arcuate shape. On the concave side of this arch a lever arm mechanism is provided which is rotatably connected to the leaf spring via two separate fastening devices.
  • the jumping device has a base plate, on which a foot can be placed in each case, and which is connected to the one fastening device via at least one pivot bearing and a connecting strut.
  • DE 199 15 813 C1 discloses a recreational and sports device for increasing the jumping power of the legs during the jumping phase by releasing an energy stored during the subsequent jumping phase as a result of the user's own weight of the energy stored during the pushing-off.
  • the device presented is composed of a basic profile with a footplate, which is designed so that the respective shoe, preferably a high-calf boot, can be accommodated in the front area, which means that the entire leisure and sports device is on the calf side of the high-shaft boot is attached to this.
  • the invention is based on the object of providing a device for moving people that is as simple and easy to use as possible.
  • the device should primarily be used as a game or sports device and should be used for physical exercise. It should have a greater stability in use. This should make it possible to use the described jump shoe safely and with the least possible risk without noticeably restricting the natural running and jumping movement.
  • the main features of the invention are set out in the characterizing part of claim 1.
  • the jumping shoe according to the invention includes all the features of claim 1.
  • a jumping shoe is provided with a foot part, which has a flat support plate for a foot or a shoe, a guide connected to the foot part, a connecting element that is mounted longitudinally displaceably along the guide, a first energy storage element that is attached to a displacement of the connecting element along the guide is biased, a bottom part which forms the contact point of the jump shoe with a ground, an elongated connection which is connected to the bottom part via a first bearing shaft and an angle element, a second energy storage element which is connected via a second bearing shaft is connected to the connection element and to a third bearing shaft with the connection, a support body which is connected to the connection element via the second bearing shaft and to the connection via a fourth bearing shaft, the fourth bearing shaft between the third bearing shaft and the first bearing shaft at d he connection is arranged; a deflection element, which is connected to the foot part via a fifth bearing shaft and to the connection and the support body via the fourth bearing shaft, the energy storage device being preloaded around the first bearing shaft when the
  • This structure results in greater stability during use, because the forces acting are absorbed particularly reliably.
  • bearing shafts are connecting elements which enable the components that connect them to rotate relative to one another.
  • energy storage elements are components which are elastically deformed by the forces acting on the energy storage element and thereby provide a restoring force in the starting position.
  • a third energy storage element is provided between the angle element and the connection, for example, which is pretensioned when the connection is pivoted relative to the angle element about the first bearing shaft.
  • the third energy storage element is designed so that a user can keep his balance while standing and the Jump shoe can be brought into its starting position.
  • the energy storage element also contributes to greater stability and a longer service life of the jump shoe.
  • a sixth bearing shaft can be provided between the angle element and the connection, the axis of which runs essentially perpendicular to the axis of the first bearing shaft, a fourth energy storage element being provided which is pretensioned when the connection is pivoted relative to the angle element about the sixth bearing shaft. If the jump shoe is subjected to a step angle under a lateral inclination, the bottom part compensates for the step angle and the third energy storage element absorbs the acting force, the jump shoe rotating around the fourth bearing shaft.
  • the third and fourth energy storage elements can for example be designed as torsion springs or have at least one compression or tension spring.
  • the first and the second energy storage element can each be designed as tension, compression or leaf springs. Suitable and frequently used materials for this are spring steels such as EN 10270-1, EN 10270-2 or EN 10270-3. Other materials such as rubber or plastics are just as possible, as are combinations of the above-mentioned materials.
  • the guide is preferably arranged essentially perpendicular to the support plate.
  • the angle between the support plate and the guide can be adjustable and in particular be from 85 ° to 95 °.
  • the guide is rigidly connected to the foot part, so that a direct transfer of the movement of the shoe 50 and thus the support plate to the elements of the jumping shoe is made possible.
  • the guide is arranged parallel to the user's leg. This has the effect that in the event of a jump, the vertical z-component of the force acts parallel to the guide.
  • lever ratios between the components that are movable relative to one another are the lever ratios between the components that are movable relative to one another. These leverage ratios determine how the acting components are divided along the z-axis. Basically, the ratio of the mentioned lever lengths is equal to the ratio of the forces acting on the first and the second energy storage element.
  • the lever length between the bearing shaft and the first bearing shaft corresponds to the lever length between the bearing shaft and the third bearing shaft.
  • the forces acting on the first energy storage element and the second energy storage element are equal.
  • the lever length between the fourth bearing shaft and the third bearing shaft can be smaller than the lever length between the fourth bearing shaft and the first bearing shaft.
  • the jump shoe becomes more compact, the smaller the lever length between the fourth bearing shaft and the third bearing shaft with the same lever length between the fourth bearing shaft and the first bearing shaft. This also has the effect that the second energy storage element has to absorb a correspondingly larger acting force.
  • the support body can be curved between the second bearing shaft and the fourth bearing shaft. If the support body were straight, it could rest against the support plate, which could impair the spring travel of the jump shoe.
  • the curvature is preferably selected so that the support body can move freely over a defined pivoting range without hitting other elements of the jump shoe.
  • the support body is preferably curved away from the support plate.
  • At least one buckle is provided on the jump shoe, which can be attached to the end of the guide facing away from the foot part. This is used to connect the jumping shoe to a leg of the user.
  • the foot part, the buckle and the guide are designed in such a way that they form a connection for the jumping shoe with one leg.
  • At least one shoe binding can be provided on the jumping shoe, which is fastened to the foot part and can be connected to a shoe located on the foot part.
  • the shoe binding is used to securely fix the shoe on the foot part.
  • the jumping shoe can also include a leg attachment.

  • the jump shoe is preferably used as a jump shoe system with two jump shoes, one jump shoe being provided for each shoe.
  • the jumping shoe 100 has a foot part 9 with a flat support plate for a foot or a shoe.
  • the foot part 9 is firmly connected to a guide 11 on which a connecting element 6 is mounted so as to be longitudinally displaceable.
  • a first energy storage element 7 is provided on the guide 11, which is pretensioned when the connecting element 6 is displaced along the guide 11, here when it moves vertically upward.

  • the bottom part 1 is connected to the foot part 9 or the guide 11 via a lever arrangement consisting of an elongated connection 3, a support body 4, a deflection element 5 and a second energy storage element 8.
  • the elongated connection 3 is pivotably connected to the angle element 2 via a first bearing shaft 12.
  • the energy store 8 is pivotably connected to the connection element 6 via a second bearing shaft 13 and to the connection 3 with a third bearing shaft 14.
  • the support body 4 is pivotably connected to the connecting element 6 via the second bearing shaft 13 and to the connection 3 via a fourth bearing shaft 15, the fourth bearing shaft 15 being arranged between the third bearing shaft 14 and the first bearing shaft 12 at the connection 3.
  • the deflection element 5 is pivotably connected to the foot part 9 via a fifth bearing shaft 16 and to the connection 3 and the support body 4 via the fourth bearing shaft 15.
  • the second energy store 8 is arranged in such a way that it is preloaded around the first bearing shaft 15 when the connection 3 and the supporting body 4 move.
  • the connecting element 6 When the foot part 9 moves relative to the bottom part 1, the connecting element 6 is displaced along the guide 11 and the angle element 2 and the connection 3 are around the first bearing shaft 12, the connection 3, the support body 4 and the deflecting element 5 around the fourth bearing shaft 15 , the connection 3 and the energy store 8 pivoted around the third bearing shaft 14, the support body 4 and the connecting element 6 around the second bearing shaft 13 and the deflecting element 5 and the foot part 9 around the fifth bearing shaft 16 relative to one another.
  • the foot part 9 is designed in such a way that it can accommodate a shoe 50.
  • the shoe sole is preferably aligned parallel to the foot part.
  • the guide 11 is preferably oriented approximately perpendicular (approx. 85 ° -95 °) to the foot part 9. Furthermore, it is rigidly connected to the foot part 9 so that a direct transmission of the movement of the shoe 50 to the elements of the jumping shoe 100 is made possible.
  • the guide 11 is then arranged parallel to the leg 60 of the user. This has the effect that in the event of a jump, the z-component of the force acts parallel to the guide. When the user jumps in place, this is the most important force component.
  • the bottom part 1 is designed in such a way that the user receives support in keeping his balance.
  • the size of the bottom part 1 is in relation to the force that the user needs to balance.
  • the bottom part 1 is preferably made of plastic or a non-rusting metal, encased by a rubber mixture in order to ensure that it adheres to the ground.
  • the energy storage element 8 is connected to the guide 11 in the connecting part via a second bearing shaft 13 and the connecting element 6 rotatably fastened to this bearing shaft 13. As a result of the rotatable fastening, the energy storage element 8 can also absorb force components acting horizontally along the x-axis.

  • a third energy storage element 20 for absorbing force components along the z-axis is provided on the first bearing shaft 12. This additional energy storage element 20 contributes to greater stability and a longer service life of the jump shoe in that the compensation takes place directly on the base part 1.
  • the third energy storage element 20 is designed so that a user can keep his balance while standing and the
  • Jump shoe 100 can be brought into its starting position. These sizes depend on the weight of the user.
  • the third energy storage element 20 provides a force that the jump shoe 100 into the in Figure 1 The middle position shown is applied so that the user is supported in maintaining his balance. The force provided by the third energy storage element 20 is sufficient to bring the jump shoe into its starting position. The jumping shoe 100 would thus stand by itself and would not fall over if the operator places the jumping shoe 100 on the ground without using it.
  • connection 3 then rotates around the bearing shaft 15 and is supported on the foot part 9 via the deflection element 5, which rotates around the fifth bearing shaft 16.
  • the bottom part 1 and the angle element 2 rotate simultaneously about the first bearing shaft 12 in order to change the position of the user in relation to the ground 200 so that the foot part 9 is aligned parallel to the ground 200.
  • the force that occurs is absorbed by an energy storage element 20.
  • the course of the directions of movement of the fifth bearing shaft 16 in the direction of the z-axis is independent of the course of the first bearing shaft 12. If the operator shifts his balance on the foot part 9 forwards or backwards, these move independently of one another. This effect helps the operator to keep his balance when stepping on.
  • the jumping shoe 100 When the jumping shoe 100 is in the compressed position, the first and the second energy storage element 7, 8 are tensioned. As a result, a vertical force, directed upwards in the z direction, acts on the footplate 9 and supports the user in performing a jump.
  • lever ratios between the components that are movable relative to one another are important aspects of the device according to the invention. These leverage ratios determine how the acting components are divided along the z-axis.
  • the distance of the lower edge of the foot part 9 from the upper edge of the connecting element 6 along the guide 9 corresponds to a lever length L1.
  • the distance between the second bearing shaft 13 and the third bearing shaft 14 corresponds to a lever length L2.
  • the length of the connection 3 from the first bearing shaft 12 to the bearing shaft 15 corresponds to a lever length L3.

  • the lever length L5 corresponds to the length of the deflection element 5.
  • the lever length L6 specifies the distance between the front edge of the support plate and the fifth bearing shaft 16.
  • ratio of L3 and L4 is equal to the ratio of the forces F7 and F8 acting on the energy storage element 7 and the energy storage element 8.
  • the jumping shoe 100 becomes more compact the smaller the lever length L4 is while the lever length L3 remains the same. This has the effect that the energy storage element 8 has to absorb a correspondingly larger acting force.
  • the maximum force to be absorbed by the energy storage elements should be at least a factor of 2, preferably 3, greater. In the above example this would be around 800 N or around 1500 N.
  • the energy storage capacity should be a factor of 5, preferably a factor of 10, greater. In the example system this would be approx. 400 J or approx. 800 J.
  • the energy storage devices must be designed in such a way that they can safely absorb and release this energy.
  • the energy storage elements must be constructed correspondingly larger.
  • a sixth bearing shaft 17 is provided on the base part 1, around which the jump shoe 100 can be pivoted about the x-axis relative to the base part 1.
  • the jump shoe 100 also has a fourth energy storage element 21, which is pretensioned when the jump shoe 100 rotates relative to the base part 1 about the x-axis. If the jump shoe 100 is subjected to a lateral inclination with a stepping angle ⁇ > 0, the bottom part 1 compensates for the stepping angle and the energy storage element 21 absorbs the acting force, the jumping shoe 100 rotating around the sixth bearing shaft 17.
  • the jumping shoe 100 further comprises a buckle 10. This can be attached to the end of the guide 11 facing away from the foot part 9 and is used to connect the jumping shoe 100 to a leg 60 of the user.
