Definitions

• the invention relates to a reinforcement device for a ski or snowboard boot.
• Ski or snowboard boots are designed so as to have great rigidity in the longitudinal direction, that is to say from front to back. Most known shoes have this quality. But another problem appeared, it is the fact that by increasing the longitudinal rigidity one also increases the transverse rigidity of the shoes. If great longitudinal rigidity is an advantage, it is not the same for transverse rigidity. Indeed, the ski or snowboard boot must have a certain flexibility in the transverse direction.
• the invention aims to provide a device intended to be introduced into existing shoes in order to increase their longitudinal rigidity while retaining their transverse flexibility.
• the invention also aims to provide a shoe comprising a reinforcement device to increase its longitudinal rigidity while retaining transverse flexibility.
• the reinforcement device in the embodiment shown in the single figure has a relatively low base.
• plane 7 intended to come under the sole of the foot.
• the base 7 can be made so as to have a length equal to the sole of the shoe for which it is intended, that is to say to have a length equal to the sole of the foot.
• the base 7 can also have a shorter length than the sole and it can have openings.
• the base 7 has at its rear end, intended to come under the heel, an element 1 substantially perpendicular to the base 7 or better constituting an acute angle with the base 7. Part 1 is intended to wrap the rear of the leg from the heel to the calf.
• the element 1 is divided into two parts 1a and 1b, by a cut or slit 2, which extends from the heel to its upper part close to the calf.
• the two parts 1a, 1b constituting the element 1, that is to say in the zone where the part 1 is intended to come into contact with the calf comprise a connecting element 3.
• the element of connection is constituted in the embodiment represented by a rectangular plate 3 rigidly fixed on the part 1b, for example by two rivets 4, while it is fixed in a mobile way on the part 1a, for example by a rivet 6 which can move in an oblong vertical opening 5 provided in the plate 3. It is obvious that the plate 3 can be different from a rectangle for example: square, round, oval, etc.
• plate 3 can also be replaced by a vertical slide on only part or the entire height of part 1.
• the device according to the invention is made either of synthetic material or of light metal such as for example aluminum alloys.
• the device according to the invention can be inserted into a ski or snowboard boot and be fixed or not to the latter. It can also be part of the shell or the upper (for flexible snowboard boots) of the boot and be fixed to the latter at the time of its manufacture. It is clear that the present invention is not limited to the single embodiment described above by way of example, but, includes all the variants that a person skilled in the art can conceive in particular with regard to the device authorizing transverse movement.
