Abstract: An inline frame for an inline skate, designed to mimic the properties of an ice hockey skate blade on ice. The inline frame includes at least one first connection part intended to be connected to a boot and at least two wheels positioned essentially in the inline frame's longitudinal direction. The unique thing about the inline frame is that it includes an upper chassis section and a lower chassis section which via a coupling element are arranged to be rotatable in the inline frame's longitudinal direction, and that the upper chassis section includes at least one first contact surface and that the lower chassis section includes at least one second contact surface, where at least one of the first contact surface and the second contact surface is curvilinear.

Abstract: A skate boot appliance for absorbing impact force of landing skating maneuvers by disposing a plunger or displacement member in a receptacle in response to an impact force, such that the receptacle is attached to a skate boot bottom and has a counterforce mechanism for resisting displacement below a threshold force, and resiliently deforming in response an impact force greater than the threshold force. The impact force is transferred from a skate blade through the plunger in response to a figure skating maneuver The disclosed plunger has a post and a horizontal displacement portion adapted to be disposed through the receptacle and engage the counterforce mechanism, such as the resilient planer member, in response to the threshold impact force, in which the horizontal displacement portion includes a convex ridge or protrusion for engaging the resilient planar member along an annular surface defined by the convex ridge.

Abstract: An in-line roller skate has a boot for accommodating a person's foot, a frame connected to the boot, and at least two wheels connected to the frame at a mutual distance in the skating direction for rideable support of the boot. The frame has a first frame portion and a second frame portion, wherein at least one wheel is connected to each frame portion and wherein the first frame portion and the second frame portion are mutually movable between a riding position and a braking position.

Abstract: Disclosed is an aesthetic and functional skating boot for roller skates, ice skates or inline skates having a lace-less cowboy boot outward appearance. From the exterior, the skate boot resembles a slip-on cowboy boot, comprising a continuous vamp region connecting to a quarter region that provides stability for the user's ankles or alternatively shrouds an internal lacing structure. A skate wheel or blade frame is affixed to the boot outsole and heel lift, connecting to at least two regions of the boot for support of the frame. Interior ankle support within the boot quarter comprises either increased ankle padding or alternatively an internal tongue and lacing structure, similar to a standard pair of laceable skates. Further disclosed is a rear brake or wheelie bar mounted to the boot in the style of a boot spur. The boot provides a fashionable exterior with adequate ankle support, preserving their functional performance.

Abstract: The invention concerns a braking device (4; 16) for a wheeled sports item (1; 15) to be applied to the foot of a user, for example a roller ski (1) or a roller skate (15), comprising an elongated body (2; 17) associated with two wheels (3a, 3b; 22), wherein the braking device (4; 16) comprises a platform (5; 18) associated with the elongated body (2; 17) defining a supporting surface (5a) for said foot, and means (6; 20) for braking the wheels (3a, 3b; 22). The device (4) comprises also means (7) for connecting the platform (5; 18) to the elongated body (2; 17), which define a rotation axis (Y) orthogonal to the supporting surface (5a), in order to allow a torsion of the foot, and control means (8) sensitive to the torsion of the foot for the operation of the braking means (6; 20).

Abstract: A roller blade having a frame, at least two rolling systems and a braking system. The frame has a plate on which the rolling systems and a foot blocking device are mounted in line. The braking device includes a braking component. The plate has two portions, one of which, a so-called fixed portion, receives the braking component, and the other one, a so-called mobile portion, receives at least one of the rolling systems positioned under the braking component in order to come into contact with the latter and slow it down when the mobile plate moves closer to the fixed portion.

Abstract: The invention relates to a skating sports device, in particular skating boot, comprising an exchangeable blade holder (14), connected to a boot by means of sole and heel plates (4 and 5). An exchangeable blade (1) may be clipped in the exchangeable blade holder (14), which is held under tension in the front and rear region by locking clip buttons (2) which may be operated without tools. A torsion duplex cross (3), formed by torsion and flexion bars (3a and 3b) absorbs the torsion and flexional forces occurring during skating and neutralizes the same.

Abstract: A skateboard comprises a board, two wheel units attached to an underside of the board, and a braking member attached to the underside of the board. The braking member includes at least one metallic braking block that is in contact with ground during braking. The metallic braking block sparks during braking to provide an amusement effect.

Abstract: An in-line roller skate incorporating at least one counter-rotatable braking device and at least one raised braking wheel in the front of the skating wheels. The braking wheel has upward freedom of movement toward the braking device so that the braking wheel is in contact with the braking device when the skate is tilted forward onto the braking wheel. The counter-rotatable braking device resists rotation of the braking wheel in the backward skating direction to provide skid free braking effect against the skating surface in proportion to the weight applied to the braking wheel and allows free rotation of the braking wheel along the skating surface in the forward direction in the event the braking wheel unintentionally contacts the skating surface.

Abstract: A braking device, particularly usable for skates comprising a shoe composed of a quarter which is articulated to a shell associated with a supporting frame for two or more wheels, and comprising at least one traction element which is connected at one end to a tab which protrudes from a braking element which is located in a region which is adjacent to the last wheel and oscillates in contrast with at least one flexible element. In the braking device, the traction element is associated, at its other end, with two levers which operatively interact with the quarter and allow to take up the traction element when the quarter oscillates backward so as to place the braking element in contact with a braking surface.
