Definitions

  • the invention relates to a ski boot with a lower shell that is open at least in the bend and an adjoining instep part up to the upper edge essentially in the longitudinal center, which is also open at the rear and can be closed here by a pivotable lid, and a cover bridging the opening of the lower shell , which preferably extends into the shaft area of a possible shaft of the ski boot, the cover being designed as a one-piece shield made of elastically flexible material and connected at its front end to the front end of the lower shell.
  • the covers mentioned are as shields with folds, e.g. B. executed in the manner of a bellows to facilitate the bending of the shaft part against the foot part of the shoe with a presentation of the skier or with a pressure of the foot on the front part of the shoe.
  • folds e.g. B. executed in the manner of a bellows to facilitate the bending of the shaft part against the foot part of the shoe with a presentation of the skier or with a pressure of the foot on the front part of the shoe.
  • the fold parts adversely press against one another and bulge the cover and the lower shell sideways, so that on the one hand there is uncomfortable pressure on the foot in the area of the bend and instep and on the other hand the holding effect of the shoe on the foot and thus the desired transfer of forces from the foot to the ski is also unsatisfactory.
  • scale-like elements also include a cuff, which has the disadvantage that when the foot is bent, it extends in the direction of travel the force exerted by the cuff can only be introduced into the cuff, which can result in a lateral bulge, and the foot of the skier in this part of the boot measures the required good grip. Furthermore, the cover pulls the central opening of the shell together, as a result of which the shell does not give the foot a good grip and unpleasant pressure points arise.
  • a ski boot with one that is made up of scales overlapping individual elements existing shield proposed as a cover for the central opening of the lower shell. So that the individual elements can adapt to the movement of the skier's leg, they are connected to one another at least on the instep side in the longitudinal direction of the shoe by a flexible core. According to one embodiment of the known shoe, the lowest shield element is connected to the lower shell. This version has proven to be advantageous in certain cases.
  • a ski boot shell made of plastic has become known, which has on the front a slot that extends to the upper edge of the shell, which is deposited by a tongue made of a material whose Shore hardness corresponds at least to the Shore hardness of the shell .
  • the tongue is held down on the shell in the instep area and articulated to the shell at the front end.
  • EP-A2-0 053 340 discloses a shell part which overlaps a tongue part in the manner of a saddle and is connected to the shell part both pivotably about a horizontal axis and displaceably in the longitudinal direction of the shoe. This construction also did not bring a solution satisfactory in the direction of the objects set by the present invention.
  • the object of the present invention is a ski boot, in which the disadvantages of the known ski boots are avoided and, in terms of production and construction, as simple as possible and thus both cheaper and functionally reliable construction of the cover, the pressure exerted on the front part of the shoe, for example when the skier presents it without any risk of a lateral bulging of the shell over the instep area against the tip of the same and there is no uncomfortable pressure on the bending or instep area of the foot, the force-deflecting effect of the cover should be optimized and the forces occurring when the skier is presented over the instep area of the foot must be guided away without widening the lower shell laterally and applying vertical pressure to the instep area of the foot is to be exercised.
  • an elastically flexible element is provided substantially in the longitudinal center of the cover, which is only longitudinally displaceable at least from the area of the bend, preferably from the shaft area of the cover, to the front end of the cover stored and with its rear end connected to the cover, preferably in the area bridging the opening of the lower shell in the shaft area.
  • the pressure is now introduced into the one-piece shield and passed over the instep area of the foot without the lower shell bulging sideways and reducing the hold of the foot in the shoe or pressure being exerted on the foot.
  • An introduction of the force exerted by the skier's foot over the instep area of the foot and into the tip of the lower shell can be achieved in that the flexible element with its front end is intended to be supported against a stop at the front end of the cover .
  • the connection of the flexible element to the shaft part of the cover causes a thrust in the longitudinal direction of the element, which thus extends forwards over the instep area and further over the supporting area of the cover and its connection to the front end of the lower shell in this is initiated.
  • the support against the stop at the front end of the cover and the resulting reaction forces provide support for the foot and very precise feedback on the presentation or the bending state of the foot to the skier, which is particularly important for the sporty driver or the racer Help is.
  • the elastically flexible element preferably has a higher rigidity than the cover itself, which ensures particularly good and exact power transmission.
  • a strip is used in at least one of the slots, preferably made of material with different elasticity in relation to the element and preferably removable.
  • the front end of the element is provided with lateral shoulders which are intended to rest against rear stops in the cover.
  • the front end of the element is thus limited in its rearward mobility and can build up and transmit a tensile force which counteracts a further displacement of the element towards the rear and thus a further inclination of the shaft part of the shoe towards the rear.
  • the cover is at least in the area above the instep and the bend in the areas where it is covered by the closure devices of the ski boot, less thick and narrower than in the other areas.
  • the element is held above the element in the thicker areas by transverse webs of the cover and lies downward free, and is the element in the thinner areas of transverse webs held below the element and directly above the opening of the lower shell webs of the cover and is exposed upwards.
  • the cover in its front section preferably in the longitudinal direction just behind the connection point with the lower shell of the ski shoe, has a nose which extends in the transverse direction and which Nose engages in a slot extending transversely between the toe part of the lower shell and the possibly overlapping side parts in the instep area of the lower shell.
  • the support force is also distributed over a larger area.
  • FIG. 1 shows the lower shell 1 of the ski boot according to the invention, which also includes a sole 11 in connection with the shaft section 12 which can be pivoted in the longitudinal direction of the boot with respect to the lower shell 1.
  • a cover 13 which can also be pivoted in the longitudinal direction of the shoe is provided. After boarding, d. H. during use of the shoe, this is by means of known locking devices attached to the lower shell 1, the shaft part 12 and / or the lid 13, for example by means of the buckles 5 or one or more shown, from one side of the lower shell 1 to the opposite side running rope (s), closed.
  • a flexion movement of the foot is preferably possible due to the longitudinally pivotable attachment of the shaft part 12 via the connection 14 and also the rear cover 13 (connection not shown).
  • a cover 4 is provided essentially in the longitudinal center of the shoe, the design, arrangement and connection thereof with the remaining parts of the shoe being described below.
  • Fig. 2 is schematically only the lower shell 1 of the ski boot, which has both a substantially longitudinally central opening 2 of the instep and flexion part of the boot, which extends into the shaft area, and an opening 3 on the heel side, which preferably from lid 13 which can be folded away towards the rear or can be opened for easier entry into the shoe, shown.
  • the opening 2 of the lower shell 1 is bridged by a one-piece, shield-like cover 4, which in the example shown is overlapped by the already mentioned locking elements 5, which locking elements 5 connect the two sides of the lower shell 1 and press them together, and after the shoe is closed, the cover 4 additionally fix over the opening 2.
  • an elastically flexible element 8 is connected in the manner of a core, this connection being provided in the flex area of the cover or in the shaft area.
  • this connection is no further fixed connection between cover 4 and element 8, but only a guide is provided in the longitudinal direction of cover 4, so that element 8 is displaceable in the longitudinal direction with respect to cover 4 when the shaft part of cover 4 is opposite Instep part is bent.
  • the element 8 is held and guided in the cover 4 by webs 43 on the upper side of the element 8 or webs 43 on the underside thereof. The webs 43 lie directly on the lower shell 1 and bridge its opening 2.
  • the forward displacement of the element 8 in the cover 4 is limited by a stop 44 at the front end 41 of the cover 4, against which stop 44 the front end 81 of the element 8 comes to rest when the shaft part of the cover 4 bends relative to the instep part.
  • the force leading to turning is introduced via the element 8 over the instep of the foot to the top of the cover 4 and from there via the fixed connection 6 into the front end of the lower shell 1, without perpendicular to the lower shell 1 and the foot to press.
  • a reaction force arises from the abutment on the stop 44, which is again directed onto the foot via the element 8 and its connection 7 with the shaft part of the cover 4.
  • the cover 4 is preferably bent up at the front or, as in the case shown, provided with a shoulder 45 which essentially forms a semicircle which is open towards the rear.
  • Two shoulders 46 facing the longitudinal center of the shoe and the cover 4 are provided so that the front end 81 of the element 8, which is congruent to the semicircular heel 45 and the heels 46, cannot be pulled backwards. This is because the element 8 is not the pressure on its front end 81 when the foot is bent forward can escape laterally, given a better fixation.
  • the element 8 supports the foot-supporting effect of other parts of the shoe, since the element 8 can also transmit tensile forces due to the fixing of the front end 81 and the fixed connection via the screw or rivet 7.
  • the front end 81 of the element 8 is designed to be elastically shock-absorbing, preferably in the form shown by slots running transversely to the longitudinal direction 82, which allow the front end 81 of the element 8 to be pushed together.
  • a single slot in the front end 81 of the element 8 is sufficient, and the number and dimensions of the or each slot 82 can influence the reaction force and damping of the forward movement.
  • a material with preferably different elasticity compared to the material of the element 8 can be inserted or removed in one or more of these slots 82.
  • the cover 4 in the area of these closing elements 5 is preferably both narrower and thinner than in the area between the closing elements 5.
  • FIG. 5 Another advantageous variant of the cover 4 is shown in FIG. 5.
  • an elongated nose 47 is provided which extends transversely to the longitudinal direction of the cover 4 and thus also the ski boot.
  • This lug 47 is preferably located below the first web 42 because of the great stability and strength of the cover 4 there, and it preferably lies with its front against the rear edge of the toe part of the lower shell 1 of the shoe. The force exerted on the cover 4 in the longitudinal direction of the shoe is thus divided between the rivet, screw or the like 6 and the nose 47.
