Definitions

  • the present invention regards a ski-boot having an improved structure.
  • the present invention regards a ski-boot that is particularly suitable for use in various sports activities, such as, for example, alpine skiing, ski-mountaineering, telemark, free-ride, etc..
  • a ski-boot generally comprises a shell, at least partially made of plastic material, a sole, fixedly connected to the shell, and a cuff or collar, which extends from above the shell to receive, at least partially, the bottom portion of the user's leg.
  • the skier must be able to bend his legs properly in pre-defined directions, forwards and, especially when curving, laterally with respect to the direction of skiing.
  • Some ski-boots of a known type present particularly flexible structures that enable the user to bend his legs easily.
  • the US patent No. US3945134 describes a ski-boot comprising a collar provided with a plurality of aeration holes, which are uniformly distributed over the entire surface of the collar.
  • the US patent No. US4825566 describes a ski-boot comprising a collar provided with a plurality of vertical slits for facilitating insertion of the user's foot.
  • ski-boots of a known type are provided with means for enabling the user to bend his leg easily, when skiing, only in a certain pre-defined direction.
  • the European patent application No. EP253306 describes a ski-boot comprising a collar provided, at the front with respect to the user's leg, with a plurality of slits, designed to facilitate bending forwards thereof.
  • the European patent application No. EP317798 describes a ski-boot comprising a collar provided, at the front and at the rear with respect to the user's leg, with elastic bellows-like structures, designed to facilitate bending forwards and backwards thereof.
  • the US patent No. US6009639 describes a ski-boot comprising a collar provided, at the rear with respect to the user's leg, with a plurality of parallel corrugations, designed to facilitate bending backwards thereof.
  • Said boots in fact, facilitate bending of the user's leg only forwards or backwards, i.e., according to a pre-defined direction substantially parallel with respect to the direction of skiing.
  • the collar of said boots laterally presents a substantially rigid structure, which enables lateral bending to be performed with some difficulty.
  • the main aim of the present invention is to provide a ski-boot that will enable the drawbacks highlighted previously to be overcome.
  • one of the objects of the present invention is to provide a ski-boot that is able to favour lateral bending of the user's leg during skiing, in particular when curving.
  • Another object of the present invention is to provide a ski-boot that, at the same time, will provide an adequate support for the user's leg and that will enable an effective transmission of the force from the user's leg to the ski to be obtained.
  • Not the least important object of the present invention is to provide a ski-boot that is relatively simple to industrialize, at contained and economically competitive costs.
  • the present invention relates also to a collar for ski-boot, according to the following claim 12.
  • the ski-boot comprises a shell, which is designed to accommodate the user's foot, and a sole, which is fixedly connected to said shell and positioned at the bottom thereof.
  • a collar extends from above the shell so as to receive, at least partially, the bottom portion of the user's leg.
  • the collar comprises a half-shell, designed to support the user's leg at the rear and at the sides, and one or more flaps designed to wrap round and support the user's leg at the front.
  • Said half-shell is provided with at least one flexible side region, positioned at the top of the malleolar area of the user's leg.
  • Said flexible side region is designed to bend in a predefined and reversible way, so as to favour lateral bending of the user's leg when skiing.
  • the ski-boot according to the invention enables the drawbacks of the known art to be overcome.
  • the presence of one or more flexible side regions on the half-shell of the collar makes it easier for the user to bend his leg laterally, in particular when he is curving.
  • the remaining structure of the collar constitutes a rigid frame that enables the user's leg to be supported adequately as well as the forces to be transmitted effectively to the ski.
  • the ski-boot 1 comprises a shell 2, designed to accommodate the user's foot at least partially.
  • the shell 2 is preferably made of plastic material and has a substantially rigid structure.
  • the ski-boot 1 also comprises a sole 3, which is fixedly connected to the shell 2 and positioned underneath it, and a collar 4, which extends from above the shell 2, overlapping it at least partially.
  • the collar 4 is designed to receive, at least partially, the bottom portion of the user's leg 8 and it comprises a half-shell 5, designed to support the user's leg at the rear and at the sides, and one or more flaps 6 designed to wrap round and support the leg 8 at the front.
  • the half-shell 5 is substantially rigid but it comprises at least one flexible side region 50, positioned above the malleolar area 7 of the leg 8. As may further be noted, the side region 50 can extend partially also to one of the flaps 6.
  • the side region 50 is designed to bend in a predefined and reversible way so as to favour lateral bending (arrow 9 of Figure 2) of the leg 8 during skiing.
  • the flexible side region 50 bends (dashed line 13), in a direction 10 substantially parallel with respect to the plane of the resting surface 91 of the user's foot and orthogonal with respect a longitudinal principal axis 12 of the ski-boot 1.
  • the side region 50 bends in a direction opposite with respect to the direction (indicated by the arrow 14) of the force exerted on the top edge 42 of the half-shell 5.
  • the side region 50 preferably comprises one or more lateral cavities (reference numbers 500, 510 and 520) made in the thickness of the wall of the half-shell 5.
  • the presence of the lateral cavities 500 bestows a high degree of flexibility on the flexible side region 50.
  • the decrease in the cross section of the lateral cavities 500 enables accumulation of a certain amount of elastic energy in the flexible side region 50.
  • Said accumulated elastic energy is substantially proportional to the degree of lateral bending of the collar 4.
  • the accumulated elastic energy is released reversibly by the flexible side region 50 and is transmitted, at least partially, to the ground. In this way, there is a significant increase in the thrust that the user can impart on the ski when coming off a curve.
  • the half-shell 5 advantageously comprises also rigid areas 11, for example, the rear bottom area of the collar 4, capable of supporting the leg 8 adequately and transmitting the forces from the leg 8 to the ski effectively.
  • the lateral cavities 500 can be, for example, cavities that pass through the thickness of the wall 501 of the half-shell 5, in an area corresponding to the side region 50 ( Figure 13A).
  • a through cavity 500 can be easily obtained by using known techniques, such as, for example, processes of moulding, perforation, cutting, punching or other methods of selective removal of plastic material.
  • the lateral cavities 500 can be blind cavities made in the thickness of the wall 501 of the half-shell 5 ( Figures 13B-13D).
  • a blind cavity 500 can be advantageously made in an area corresponding to the external surface 502 of the wall 5 or 1 ( Figure 13C).
  • the external surface 502 is, in practice, the surface of the collar 4 that faces the outside of the boot.
  • a blind cavity 500 can be made in an area corresponding to the internal surface 503, i.e., the surface of the collar 4 that faces the user's leg ( Figures 13B and 13D).
  • a blind cavity 500 can be obtained with the known techniques described above for selective removal of plastic material.
  • a blind cavity 500 can be obtained first by providing a through cavity 500 and then associating thereto an addition of material 560 (Figure 13D), so as to close it in an area corresponding to one of the two surfaces 502 or 503.
  • the addition of the material 560 can be made using plastic material or a material, for example metal, completely different from that of the collar 4 and can be associated to the through cavity 500 according to known techniques: for example, it can be glued, riveted, screwed, soldered, or subjected to any other process designed to associate the surfaces of two components to one another.
  • the shape of the lateral cavities 500 can be designed according to the requirements. For example, they can assume a polygonal shape (Figure 3), a circular shape ( Figure 4), or an elliptical shape ( Figures 5-12).
  • cavities 500 An adequate choice of the shape of the cavities 500 enables appropriate modulation of the degree of bending of the side region 50.
  • lateral cavities 500 of an elliptical shape enables considerable increase in the lateral flexibility of the collar 4, whilst lateral cavities 500 having a circular shape bestow a lower degree of flexibility thereon.
  • the half-shell 5 preferably comprises a first flexible side region 51, positioned in an area corresponding to the portion of leg 8 overlying the external malleolar area 71.
  • the first side region 51 comprises one or more first lateral cavities 510.
  • the first side region 51 is positioned in the proximity of a median lateral area of the half-shell 5, which is comprised between a flap 6 of the half-shell 5 and the fixing areas 54 for two engagement elements (not illustrated), which are associated laterally to the half-shell 5.
  • the first side region 51 can comprise a number of first lateral cavities 510 set aligned ( Figures 3-4) and/or parallel ( Figures 7 and 9) to one another.
  • the first side region 51 can comprise just one first lateral cavity 510 ( Figures 5-6 and 8).
  • first side region 51 In the case where it is desired to increase further the flexibility of the collar 4, it is possible to extend the first side region 51 also to one of the external flaps 6 of the collar 4. In this case, one or more of the cavities 510 can be made on a first outer flap 6 ( Figures 3-5).
  • the half-shell 5 can comprise a second flexible side region 52, positioned in an area corresponding to the portion of user's leg overlying the internal malleolar area 72.
  • the second side region 52 comprises one or more second lateral cavities 520, positioned in the proximity of a bottom edge 43 of the half-shell 5 and of the collar 4.
  • the second side region 52 comprises a number of second lateral cavities 520 set aligned ( Figure 10) and/or parallel ( Figure 12) to one another or, alternatively, a single second lateral cavity 520 ( Figure 11).
  • the orientation of the lateral cavities 510 and 520 can vary according to the requirements.
  • the first lateral cavities 510 are advantageously positioned according to an axis 55 ( Figure 3) not orthogonal with respect to the plane of the ski. In this way, each lateral cavity 510 can vary more its own cross section during lateral bending of the leg, thus improving further the flexibility of the side region 51.
  • the lateral cavities 520 are, instead, advantageously oriented so as to follow as close as possible the profile of the bottom edge 43 of the half-shell 5 and/or of the flap 6 of the collar. Is has been found that this favours further lateral bending inwards of the leg 8.
  • the collar 4 of the ski-boot 1 is no longer an element that is substantially undeformable laterally but is able to change its own configuration according to the direction of the forces transmitted between the user and the ski.
  • the ski-boot can favour lateral movements of the user's leg, in particular when he is curving and/or in the presence of a non-uniform ski run.
  • the collar 4 remains laterally rigid in the case of non-lateral bending of the leg, for example. in the case of bending forwards or backwards of the leg or more in general bending of the leg in the direction of skiing. This results in a greater control over the ski during all the phases of skiing and in an improved comfort for the user.
  • the configuration of the ski-boot can be further modulated according to the requirements by varying the positioning, orientation and shape of the lateral cavities 500, 510 and 520. It is hence possible to obtain models of ski-boots having collars with differentiated coefficients of flexibility according to the requirements and capabilities of the user. For example, for a skilled user it is possible to provide a ski-boot with a more flexible collar, which will enable a stronger push to be exerted when curving. For a beginner, it is possible to provide a ski-boot with a more rigid collar, which will ensure a greater control over the ski.
  • the ski-boot according to the present invention does not present any particular aspects of difficulty from the production standpoint. In fact, it can be easily produced by means of the known techniques of moulding of plastic materials. Consequently, it has revealed relatively simple to industrialize, at contained economically competitive costs.
