Abstract: The invention relates to an inline roller skate consisting of a boot 10, 11, a removable roller unit 1-5, an interface 12 on the boot and a device for locking and unlocking the roller unit 1-5 to and from the interface 12 on the roller unit 1-5. To enable optimum rolling and, after simple removal of the roller unit, also comfortable walking with the boot, the interface 12, which preferably consists of a harder material than the boot body 10, extends upwards from the boot sole 11 laterally along the boot body 10, and the roller unit 1-5 is provided with a substantially horizontal standing plate 4 and substantially vertical side walls 5 for the reception of the interface 12, so that substantially perpendicular stepping into and out of the roller unit 1-5 is created, and the device for locking and unlocking the roller unit 1-5 to and from the interface 12 engages in the interface 12 outside the area of the boot sole 11.

Abstract: Roller skate comprising the body of a shoe (11) wherein the skater's foot and part of the leg are housed, associated with a support (12) on which the skating elements (13) are mounted, there being included at least a front skating element (13a), a middle skating element (13b) and a rear skating element (13c), the roller skate in that the shoe (11) being constrained to the support (12) at least by means of an articulated oscillation connection (19) and cooperating with the support (12) by means of a guide element (18), the skating elements (13) having a diameter of between 90 and 120 mm and the support (12) including assembly seatings for the skating elements (13) defining a first position where the skating elements (13) are substantially aligned, and a second position of vertical limit where at least the front skating element (13a) is in a raised position with respect to the skating surface (20), by a value at least one sixth of the diameter of the middle skating elements (13b) and in any case not less than 1

Abstract: A liner is disclosed for footwear, in particular for ski boots, climbing boots or the like, with a thermoplastic and a heating arrangement, and a process for adapting such a liner to the shape of the foot of the person using such a liner. In order to achieve optimum adaptation in a simple manner, it is provided that the electric heating arrangement is formed by at least one heatable film 1 which is arranged in the liner and with the aid of which the thermoplastic of the liner can be heated so that it can be adapted to the shape of the foot of the person using the liner. The or each heatable film 1 preferably comprises a flexible plastic layer on which there is arranged at least one resistance layer 2, of which the ends 7, 8 are connected to at least one connecting lead 3, which is routed outward, and at least one plug 4.

Abstract: A binding for snowboards and also to a boot with such a binding. To facilitates stepping in and out, the binding has a binding plate (5) which is provided with lateral holding (retaining) members on both sides of the boot sole in its central longitudinal zone and which is connected to a base plate (6) or the surface of the snowboard, characterised in that the retaining members are formed by side walls (3) diverging from one another conically upwards preferably in the upper portion, and disposed on the binding is a pivotable sprung clamp (1), whose ends or elements connected to the ends extend inwards through substantially horizontal holes (4) in the side walls (3), while a boot can be locked to the binding via the ends (2) of the sprung clamp (1) or elements connected thereto and can be again unlocked by the pivoting of the sprung clamp (1). The interface (12) which extends laterally upwards from the central zone of the boot sole (14) is preferably made of a harder material than the boot body (11).

Abstract: Shock absorber device for roller skates, particularly but not exclusively of the type with aligned wheels, the skates including the body of the shoe (11) wherein the foot and part of the user's leg fit, the shoe (11) being connected to a support (12) on which are mounted the elements (13) which run on the ground, the connection between the shoe (11) and the support (12) being of the articulated type (14), the device comprising an elastic foil element (21,121,221,321) shaped with at least an inverted angle and associated, at least at the ends, respectively with the shoe (11) and the support (12) at a point at a distance from the articulated connection (14).

Abstract: System for the lateral adjustment of the wheel chassis of a skate (14) located between a shoe (11) and a support (12) including a removable constraint made of connection element (16) arranged substantially transverse to the direction of advance of the skate which cooperates with at least one lower extension (17) of the shoe, at least one wing (18) of the support and a spacer element (19). The spacer element comprises at least two distinct lateral portions (19a, 19b) with thicknesses (s1, s2).
