  • a shock absorber an upper and a lower part of the shoe are provided, which are connected vertically displaceably against one another and are supported against one another by spring systems, the upper part and the lower part of the shoe being guided against one another during their vertical displacement movement by interacting molded guide elements.
  • the shock-absorbing ski boot according to the invention dampens the impacts and bumps which occur during skiing and which are caused by uneven terrain.
  • the harmful influence of skiing on the human skeleton, especially on the joints and intervertebral discs, is thus prevented or at least significantly reduced.
  • the flutter of the skis is reduced when driving downhill quickly, which enables safe, fatigue-free and accident-free skiing.
  • the impact forces are absorbed by the spring system according to the invention.
  • the spring force can be adapted to the respective body weight and the driving style of the skier and shoe wearer.
  • the molded-on guide elements ensure that the upper and lower parts of the shoe are guided exactly and plane-parallel to each other during their vertical displacement movement and that the two parts of the boot are prevented from tilting.
  • set screws can be provided, by means of which the spring force of the spring elements, for example if compression springs are used, the pretension of which can be adjusted.
  • the dependent claim 5 has a spring system according to a preferred embodiment of the invention.
  • Subclaim 8 contains a guide system which can be used according to the present invention and is particularly simple and inexpensive to manufacture and consists exclusively of plastic parts. According to a preferred variant of the invention, the upper and lower parts of the shoe are detachably fastened to one another.
  • the shoe shown consists of a lower shoe part 1o and an upper shoe part 2o, wherein the lower shoe part 1o has an integrally formed circumferential guide profile 11 which is provided in a circumferential guide groove 13 formed on the upper part 2o the vertical displacement movement of the two parts is guided against each other.
  • the spring system consists of a plurality of vertically arranged coil springs (compression springs) 16.
  • tension springs 25 arranged in the longitudinal direction are provided, each of which is fastened to two transverse bolts 23a, 23b in the front shoe region or two further transverse bolts 23c, 23d in the rear shoe region .
  • the cross bolts 23a, 23b, 23c, 23d are guided at their ends in rails 12 attached to the lower shoe part 10.
  • Each pair of cross bolts is two pairs of links 22a, 22b in the front area and two pairs of links 22c, 22d assigned in the rear area, which are each arranged in a V arrangement.
  • the vertices of the handlebar pairs are articulated on the shoe upper 2o, the handlebar ends being connected to the cross bolts.
  • Two longitudinally arranged and displaceable linkages are provided, namely a front linkage 26 and a rear linkage 27, of which the front linkage 26 connects two transverse bolts 23a and 23c, while the rear linkage 27 connects the two rear transverse bolts of the respective Cross bolt pairs 23b and 23d interconnected.
  • an adjusting device is provided at least for the central vertical coil springs 16 that are subjected to pressure, by means of which the prestressing of the vertical compression springs can be adjusted in an adjustable manner.
  • the prestressing of the springs is adjusted via a set screw 17, which is guided through the sole of the lower part 10 of the shoe and can be adjusted from the outside, preferably with a steep thread.
  • the bias of the compression springs 16 can thus be adapted to the respective body weight and the driving style of the shoe wearer as well as the nature of the slope.
  • FIGS. 4 and 5 A further variant of a ski boot according to the invention equipped with a shock absorber is shown in FIGS. 4 and 5.
  • the shoe consists of a lower shoe part 1o and an upper shoe part 2o.
  • the lower shoe part 1o in turn has a circumferential guide profile 11 and on the upper shoe part 2o a circumferential guide groove 13 is formed, in which the guide profile 11 of the lower shoe part is guided against one another during the vertical movement of the upper shoe part 2o and the lower shoe part 1o.
  • An edge profile 58 formed on the outside of the upper of the shoe overlaps the guide profile 11 of the bottom part of the shoe.
  • a plurality of vertically arranged coil springs are provided for the spring system, preferably a total of four compression springs 36 arranged in pairs in the front area of the shoe and at least two further compression springs 37 in the middle of the shoe and preferably two further compression springs 38 which are arranged in pairs in the back of the shoe.
  • the compression springs 38 in the heel area can be arranged on a guide cylinder 66 integrally formed on the upper part 20 of the shoe, within which, during the vertical movement, guide cams 67 which are formed on the lower part of the shoe are guided in the manner of a piston.
  • a wedge element 39 is formed on the shoe upper 2o, which, as can be seen from FIG. 5, is approximately U-shaped in cross section.
  • a roller 40 can be rotated in this wedge element 39 stored.
  • the front wedge surface of the wedge element 39 is assigned an inclined surface 42 of a slide 41 which is arranged in the shoe lower part 10 in a horizontally displaceable manner.
  • the roller 4o mounted on the wedge element 39 slides on the two legs 53 of the slide 41, which are wedge-shaped, causing the slide 41 in the direction of arrow 43 in the horizontal direction is moved.
  • a further small wedge element 44 is integrally formed on the upper 2o of the shoe, to which an inclined surface 45 on the slide 41 is assigned. If the carriage 41 now moves forward in the direction of arrow 43, the wedge element 44 can move downward in the direction of the arrow, sliding on the inclined surface 45 of the carriage. From Fig. 5 it can be seen that the slide 41 has a crossbar 46 for stiffening, the two vertical legs of the slide being bent to the right of the crossbar, so that two legs 53 located further inside are formed.
  • the wedge element 39 is approximately U-shaped in section, the two bent leg ends 53 of the carriage lying further inward in the view according to the horizontal sectional view of FIG. 5 than the two U legs 54 of the wedge element 39, so that the roller 4o the wedge surfaces 42 formed on the legs 53 of the carriage can slide.
  • a further slide 5o is provided which, according to the view of FIG. 5, lies within the larger slide 41 and is approximately H-shaped in cross section with two left legs 55 and two right legs 65 and a crosspiece 52 connecting the two parallel legs
  • a further wedge element 47 which is likewise U-shaped in cross-section and its shape, is formed on the shoe upper part 2o in the region of the front end of the slide 41 Legs lie within the slide 41.
  • a roller 48 is rotatably mounted, which rolls on inclined surfaces 49 of the inner slide 5o when the shoe upper 2o moves downward by pressure in the vertical direction.
  • the inner slide 5o is then displaced in the direction of arrow 51 in the horizontal direction and slides backwards when the upper of the shoe moves downward in the lower part of the shoe.
  • the carriage 50 has a wedge-shaped recess in the rear region on the legs 65, so that inclined surfaces 56 are formed on the legs.
  • a further wedge element 57 is formed on the upper part 2o of the shoe, which slides downward on the inclined surface 56 of the legs of the slide 5o during the lowering movement of the upper part, the slide moving horizontally in the direction of arrow 51 to the right.
  • the device described above ensures a plane-parallel displacement and good guidance of the upper and lower parts of the shoe 1o during their vertical displacement movement relative to one another.
  • the lower shoe part 1o and upper shoe part 2o are detachably connected to one another.
  • a plurality of leaf springs 59, 64 which are arranged distributed around the circumference of the upper of the shoe, serve as the fastening device.
  • the leaf springs 59 can be attached to the shoe upper by eyelets 63.
  • the leaf springs 59 are approximately L-shaped in cross-section, a lower bend 6o of the leaf spring engaging under a projection 61 formed on the shoe lower part 1o.
  • the Leaf spring 59 designed so that it is somewhat narrower in the upper region and widens towards the bottom.
  • the vertical leg of the leaf spring is resilient, so that a tool can be passed through the bore 62 in the lower shoe part 1o, with which the leaf spring 59 is pressed backwards, the bend 6o of the leaf spring sliding backwards and thus releasing the lower shoe part 1o.
  • the same procedure is followed with the remaining leaf springs 64 when the lower part of the shoe is released.
