Abstract:
For a glide sport article, especially an ice skate with a shoe body that is located on a chassis and that includes a cap-like shoe tip forming the toe area of the shoe body, a shoe body section forming the heel area and an ankle support, lacing on the shoe body section and a tongue located beneath the lacing, the shoe tip can be adjusted in a shoe body direction relative to the shoe body section on the chassis.

Description:
BACKGROUND OF THE INVENTION 
   The invention pertains to a glide sport article, especially an ice skate and in particular to a hockey skate. 
   An object of the invention is to present a glide sport article that is especially suited for children and that enables adjustment and adaptation of the length of the shoe or shoe element to different foot sizes over a relatively large range, however while still fulfilling the requirements exhibited especially by hockey skates, above all with respect to an optimum fit on the foot of the wearer and also optimum protection and sufficient stability. 
   SUMMARY OF THE INVENTION 
   A special feature of the invention is, for example, that the shoe body section that is permanently fastened to the chassis extends over the greater length of the shoe body, or shoe, and forms its sides, the heel area and the support there for the leg area above the ankle and also contains the lacing, while the shoe tip, which is adjustable in the longitudinal direction of the shoe body, or in the longitudinal direction of the chassis, protrudes from the shoe body section only with a much smaller length. 
   A further special feature is that the tongue, located beneath the lacing of the shoe, is connected with the shoe tip and is adjusted with the latter and that the shoe body section, that is permanently connected with the chassis, overlaps the cap-like shoe tip on its outer surface, namely over an area that is greater than the maximum adjusting area of the shoe tip.

   DETAILED DESCRIPTION OF THE INVENTION 
   In the drawing,  1  generally designates a hockey skate consisting of an upper shoe or shoe body  2 , of a chassis  3  connected with the sole  4  of the shoe body  2  and supporting the latter, and of a runner  5  located on the bottom of the chassis  3 . In the depicted embodiment, the chassis  3  is essentially manufactured from plastic as a molded part. The runner  5  is made of steel. 
   The shoe body  2  comprises a shoe tip  2 . 1  and a shoe body section  2 . 2 , as is known in the art. The latter contains the usual lacing  6  on the front of the shoe body  2 , located at the top front of the shoe body section  2 . 2  and with which the shoe can be tied to the foot of the user. In the depicted embodiment, the lacing  6  reaches to the cap-like shoe tip  2 . 1 . Furthermore, the shoe body section  2 . 2  forms the heel area of the shoe  2  with an ankle support. 
   The shoe body section  2 . 2  reaches from the rear or the heel area of the shoe body to the shoe tip  2 . 1 , such that the latter protrudes forward from the shoe body section  2 . 1  with only a very small length in comparison with the overall length of the shoe body  2 . In the depicted embodiment, the length of the shoe body section  2 . 2  is at least 70% of the maximum total length of the shoe body  2 . The cap-like shoe tip  2 . 1  and the shoe body section  2 . 2  are manufactured of materials suitable for shoes for hockey skates. Furthermore, the shoe body section  2 . 2  is provided with a reinforcement on the side, i.e. with an impact guard  7 , which extends above the sole  4  and beneath the lacing  6  from the heel area of the shoe body  2  to the vicinity of the shoe tip  2 . 1 . Beneath the lacing  6  is the usual tongue  8 , which is permanently connected with the cap-like shoe tip  2 . 1 . The latter is overlapped on the outside by the shoe body section  2 . 1  and can be adjusted in stages relative to the shoe body section  2 . 2  on the chassis  3  corresponding to the double arrow A in  FIG. 1 , namely by a pre-defined, maximum adjustment distance for adapting the shoe to different foot sizes. 
   For this purpose, the shoe tip  2 . 1  can move in a guide with part of the sole  4  or with the sole element  4 . 1  on the chassis  3 . The chassis  3  comprises two rail-like ridges or guides  10 , each of which protrudes over one longitudinal side of the chassis and each of which engages in a longitudinal groove  11  on the bottom of the sole element  4 . 1 . For the formation of the grooves  11  the sole element  4 . 1  is provided with a T-shaped grooved recess  12 , which forms the guide grooves  1  with its lateral extensions. 
   On the sole element  4 . 1  there is a toothed strip  13  protruding over the bottom of the sole element and extending in longitudinal direction and therefore in the adjustment direction of the shoe tip  2 . 1  and which has a plurality of teeth  14  on its bottom side. The toothed strip  13  or its teeth  14  act in combination with gear teeth  15  located on a locking element  16 . The latter can move on bearings (double arrow B) in the chassis  3  in an axis that is perpendicular to a plane E, which encloses the longitudinal axis of the skate and is also the middle axis of the chassis  3 , namely against the effect of a pull-back spring  17  from a position ( FIG. 3 ) locking the toothed strip  13  and therefore the shoe tip  2 . 1  into a position ( FIG. 4 ) releasing the toothed strip  13  and therefore the shoe tip  2 . 1 . 
   The locking element  16 , in the depicted embodiment, and the toothed strip  13  are molded parts made of plastic. For guiding the locking element  16 , openings are provided for the locking element  16  in the walls  3 . 1  and  3 . 2  of the chassis  3 , which is designed as a hollow body, namely one opening in the wall  3 . 1  for a peg-like section  16 . 1  of the locking element on which (element) the spring  17  for this section is also located, and one opening  19  for the section  16 . 2  of the locking element. The teeth  15  are also located on the section  16 . 2 . The section  16 . 2  has a non-circular cross section, i.e. in the depicted embodiment an oval cross section, to which the opening  19  is adapted, so that the locking element  16  is held in the chassis  3  so that it is axially movable but unable to twist. On the end that is distant from the section  16 . 1 , the section  16 . 2  forms an actuating or pressure surface  16 . 3 , which protrudes beyond the outer surface of the wall  3 . 2  of the chassis  3  when the spring  17  is released, i.e. when the toothed strip is locked ( FIG. 3 ). In this state, the teeth  15  engage in the toothed strip  13 . Pressing the actuating or pressure surface  16 . 3  causes the locking element  16  to move against the effect of the spring  17  far enough that the teeth  15  disengage from the toothed strip  13 . The opening  18  is closed by a cover  18 . 1 . 
     FIG. 5  again shows, in a simplified schematic depiction, the sole element  4 . 1  in bottom view, together with the sole section or element  4 . 2  that is permanently connected with the shoe body section  2 . 2 , by means of which (sole element) the shoe body  2  or the shoe body section  2 . 2  is permanently connected with the chassis  3 , e.g. by means of rivets or other suitable fastening means. 
   In order to seal the shoe body  2  in the area of the sole  4 , especially against penetration by water, the two sole elements  4 . 1  and  4 . 2  are designed so that these two sole elements overlap at least partially in any adjustment position of the shoe tip  2 . 1 . In the depicted embodiment the overlapping is achieved by the fact that the sole element  4 . 2  comprises a tongue  20 , which engages in a recess  21  of the sole element  4 . 1 , as depicted in  FIG. 5 . 
   The invention was described above based on a sample embodiment. It goes without saying that numerous modifications and variations are possible without abandoning the inventive idea upon which the invention is based.
