Definitions

  • the invention relates to a shoe, in particular a sports shoe, wherein the sole and at least one resilient component encloses.
  • Sports shoes with a resilient sole are known and are supposed to absorb vibrations and strong shock loads in the area of the heel bone and the Achilles tendon due to the resilience of the sole, and thus have a protective effect on the joints.
  • the object of the present invention is to provide a shoe In particular to create sports shoes that can be easily adjusted and adjusted to the weight of the user to allow optimal adjustment of the shoe suspension and cushioning to the weight of the wearer and the career hardness.
  • this object is achieved in that the sole encloses an externally adjustable, mechanical spring part.
  • This spring part is advantageously arranged in the area of the heel and incorporated into the wedge present here between the outsole and the insole.
  • the mechanical adjustment of the spring part makes it possible in a simple manner to preload this spring part more or less and thus to adapt the shoe suspension to the weight of the user and the track hardness. This setting can be made very sensitively, especially if the spring part is infinitely adjustable.
  • the spring part itself is formed either as a one-piece elastomer-elastic component or a plurality of elastomer spring elements.
  • Elastomer-elastic should be understood here and in the following to be rubber-elastic, but without the spring part having to be made of rubber. It may as well consist of plastic or other elastic materials.
  • This spring part or the elastomer spring elements can either consist of a foamed or full, elastic material. In the case of the elastomer spring elements in particular, it is advantageous in terms of features if they are provided with foamed or molded cavities.
  • the damping properties can be influenced.
  • These foamed elements are preferably provided with a closed outer skin, which not only protects the surface against wear, but also a ge know additional resilient or damping enclosed gas is achieved.
  • a very simple mechanical adjustment of the spring part is obtained in that at least one tie rod arranged essentially in a plane parallel to the outsole is provided in the spring element.
  • Each tie rod is preferably in operative connection with at least one abutment in order to ensure a safe and easy adjustment as well to ensure a good fixation of the spring parts in the shoe.
  • a loss of shoe mobility is avoided in a simple manner in that the tie rod is formed by a flexible component or that the tie rod (s) consist of a cable pull.
  • tie rod is connected at its inner end to a thrust washer via a thread, since this ensures a uniform transmission of the pretensioning force to the spring elements.
  • a central web formed by the chambers can run either in the longitudinal direction or in the transverse direction of the shoe. If the web runs in the longitudinal direction, the possibility is created to compensate for foot defects by different spring hardness of the chambers.
  • the web separating the chambers is arranged in the region of the heel bone and is itself designed as a spring element and is penetrated by the tie rod and forms an abutment for the elastomer spring elements.
  • the chambers in which the spring part is accommodated can feature boundary surfaces which either have an acute angle for the elastomer spring elements. This also results in a change in the spring rate, which has a progressive or degressive character depending on the direction of taper.
  • This can be formed, for example, by a sliding film or by a powdered lubricant such as talc.
  • a particularly favorable design of the sports shoe is obtained in that the spring part is combined with the chambers and the adjusting device to form a structural unit.
  • This unit forms part of the insole, which is interchangeably connected to the shoe.
  • Knöpf16 offers, followed a Abdecksohle around the F LAE surface of the insole or in the Einknöpfriv can be attached.
  • the tie rod is connected to an adjusting key which is adapted to the contour of the sole in the rest position and which, according to the invention, is displaceable in the adjusting position for adjusting the spring preload.
  • a lock for the setting key is provided both in the rest position and in the setting position.
  • the spring part is connected to a marking, the position of which relative to the sole is a measure of the prestressing of the spring part.
  • the sole has a window through which the marking is visible.
  • the amount of the bias of the spring part is visibly displayed from the outside, so that the bias of both shoes can be adjusted evenly.
  • the window can be formed by a transparent or transparent insert in the tread of the sole. In the case of transparent sole material, a reduction in the sole thickness in the area of the window is often sufficient in order to be able to recognize the setting of the spring part sufficiently clearly.
  • this overall sole consists of a profiled outsole 1 and an insole 2 and is wedge-shaped in accordance with the shape of the foot.
  • This wedge essentially formed by the insole 2 is recessed in the area of the heel in such a way that two chambers 7 are formed, in which a multi-part spring part 4 is arranged.
  • the spring part 4 comprises two units, consisting of elastomer spring elements 5, tie rods 6, thrust washers 13 and nuts 20.
  • the elastomer spring elements 5 are arranged between two pressure disks 13 in each chamber 7.
  • the tie rod 6 passes through these parts and is supported on both sides in the insole 2 in a front bearing 9 and a rear bearing 10.
  • the tie rod 6 is provided at its shoe inner end with a thread 21, in which the nut 20, which is connected non-rotatably to the pressure disk 13, engages.
  • the pressure plates 13 are preferably positively connected to the adjacent elastomer spring elements 5, for example by protrusions on the pressure plate 13 engaging in corresponding recesses in the spring elements 5.
  • each tie rod 6 protrudes with its adjusting head 11 and thus lies against a support bearing 12.
  • the chambers 7 accommodating the spring part 4 are closed and the prestressing of the spring elements 5 can be done via the two adjusting heads 11 the tie rod 6 can be continuously adjusted separately.
  • the adjustment heads 11 are provided with corresponding surfaces for an adjustment tool.
  • the spring elements 5 are supported on the abutment 13 on the left in the figure and the nut 20 on the tie rod 6, this force being absorbed by the support bearing 12.
  • the other side of the spring elements 5 is supported via the thrust washer 13 on the abutment 3 formed by the chamber 7.
  • the spring tension of the spring elements 5 can be changed by rotating the adjusting head 11 firmly connected to the tie rod 6, about 40 revolutions of the adjusting head 11 being required between the lowest and the highest spring rate.
  • This rotary movement of the tie rod 6 causes an axial displacement of the thread 21 and the nut 20 Thrust washer 13 and thus a change in the spring rate for the spring elements 5. Due to the separate adjustment of the two in the chambers 7 arranged spring units a different spring hardness on the inside and the outside of the shoe can be achieved, thus producing F ußschreib can be compensated.
  • the spring part 4 is constructed from spring elements 5, it is readily possible to use different spring elements 5 with regard to the spring hardness. Adapting the spring properties to the weight of the person using the shoe is easily possible in this way.
  • the arrangement of the spring part 4 directly in the area of the heel bone is particularly favorable.
  • the tie rods 6 can for example be made of glass fiber reinforced plastic material in this embodiment or consist of another resilient material. It is also conceivable to replace these tie rods with a cable pull.
  • the recesses arranged in the wedge-shaped section of the insole 2 form a front chamber 14 and a rear chamber 15 for the spring part 4. Between these chambers 14 and 15 there is a crosspiece 16 which itself is designed as a spring element and is penetrated by the tie rod 6. In addition, this crossbar 16 acts as an abutment 3 for the spring elements 5 abutting the crossbar 16.
  • These spring elements 5 differ from those shown in FIGS. 1 and 2 essentially in that they have special cavities inside which are filled with gas .
  • the tie rod 6 also differs from the one already described, because in addition to the threaded section 21 provided with a right-hand thread, it carries a further threaded section 22 with a left-hand thread.
  • a bushing is provided as the front bearing 9, while the rear pivot bearing is axially ver on the tie rod sliding adjustment key 17 is formed.
  • the adjusting key 17 is non-rotatably connected to the tie rod 6, in that the tie rod 6 has a square at this end, for example, and the adjusting key has a corresponding inner square. 3, 4 and 5, the adjusting key 17 is shown in the rest position, the collar of the adjusting key 17 engaging in a lock 18. To change the spring rate, the adjusting key 17 is pulled out of this position and then engages with the collar in a lock 19. Now the spring rate of the spring elements 5 can be changed by turning the adjusting key 17 and thus the tie rod 6.
  • a clockwise rotation is carried out, the thrust washers 13 connected to the adjacent spring elements 5 and the nuts 20 being axially displaced.
  • the B-e motion of the right and left thrust washer is in opposite directions, since the thread 21 is a right-hand thread 22 and a left hand thread.
  • Appropriate stops for the axially movable parts are arranged on the tie rod 6 for the hardest and softest setting of the spring rate.
  • the bushing 9 serves the softest setting as a stop, while the threaded end forms the stop for the hardest setting.
  • the profiled outsole 1 is only glued to the underside of the insole 2 after the spring part has been installed in the insole 2. It is readily possible to connect the structural unit consisting of the spring part 4, the chambers 14 and 15 and the adjusting device to the shoe in an interchangeable manner. For this purpose, this structural unit is connected, for example by buttoning, to the inner sole 2 and a corresponding cover sole is attached over the connection point or over the entire sole area.
  • the boundary surfaces of the chambers 7 corresponding to FIGS. 1 and 2 or the chambers -14 and 15 according to FIGS. 3 and 4 can run parallel to one another or at an acute angle to one another in order to additionally achieve a progressive or degressive change in the spring rate.
  • the embodiment according to FIGS. 3 and 4 also allows a very sensitive stepless adjustment of the spring rate, since about 40 turns of the key are possible in order to move from the hardest to the softest setting.
  • the spring force changes of the individual chambers can also be varied by a corresponding pitch of the threads 21 and 22.
  • the spring part is preferably arranged in the wedge of the insole 2 in such a way that the support is provided in the area of the center of the heel.
  • the pressure plates 13 on both sides have a small height in relation to the spring elements 5, approximately one third of the height of these elements 5.
  • elastomer spring elements of uniform design are used.
  • the embodiment shown in FIGS. 6, 7 and 8 is an outsole in which the setting or preload of the spring element arranged between the outsole and the insole is visible from the outside.
  • the outsole 1 has a window 25 which is formed by a transparent or translucent insert or, in the case of a somewhat translucent outsole, by a section of thinner sole thickness.
  • the elastomeric or rubber-elastic spring element 27, which can be preloaded by the tie rod 6, is formed in one piece and is provided with cavities and depressions on the surface which improve the elasticity and damping properties.
  • the spring element 27 is supported in the heel area on a curved thrust washer 28 which is adapted to the rear outsole contour.
  • the thrust washer 28 is in turn rotatably supported on the tie rod 6 in a manner not shown. Due to its curved shape and the support directly on the tie rod 6, the thrust washer 28 can be arranged very close to the heel end of the sole, which creates space for the spring element 28 in the heel area.
  • the front thrust washer 29 screwed onto a thread of the pull rod 6 moves in the direction of the rear thrust washer 28, whereby a compensating body 26, which is preferably made of a foam, can expand accordingly and thus no cavity is created in the area of the thrust washer 29.
  • the side of the compensating body 26 opposite the pressure plate 29 is supported on a third pressure plate bent opposite to the pressure plate 28, which in turn is rotatably supported on the pull rod 6. None of the three thrust washers are thus supported on the adjacent surfaces of the sole chamber, so that the sole is not exposed to any stress.
  • the compensating body 26 and the spring element 27 have strikingly different colors.
  • the compensating body 26 is colored white or yellow and the spring element 27 is colored black or red.
  • the elements 26 and / or 27 can also be designed to be fluorescent, thereby ensuring the safety of the runner in the dark Si serving g nalwirkun g is obtained.
  • the essence of the L sole shown in FIGS. 2 to 8 consists in the transparent or translucent window, which enables a visible display of the prestress of the spring element 27. A comparison of the two shoes thus enables a uniform setting of the spring element preload of both shoes.
  • the window 25 can be of any shape and formed by an insert or a translucent portion of the outsole.
  • a triangular window is shown in FIG. 6, which widens in the direction of greater pretension. 6a shows a diamond-shaped window 25a. While the triangular or wedge-shaped window makes it easier to assess the size of the spring preload, the diamond-shaped window allows an easier comparison of the preload of the two shoes, since the center of the diamond visually highlights a medium setting.
