A skate (10) for receiving a foot of a skater includes a frame (14) holding in-line wheels (16). A rigid base (18) is securely attached to the frame (14). An external heel counter (20) extends upwardly from the base around the heel portion of the skate. An upper (12) having an outer shell of substantially soft pliable material extends upwardly from the base (18). A substantially rigid internal heel counter (34) is disposed beneath the outer shell. The internal heel counter (34) extends around the heel area of the skate (10) above the top of said external heel counter (20). A substantially rigid ankle support cuff (36) is pivotally coupled to the internal heel counter (34) and disposed beneath the outer shell.

An in-line skate is disclosed having a rigid frame (30) with a platform and having a boot (22) with a shell (24). The shell includes a sole (31). Two longitudinal parallel rails extend downwardly from a lower side of the platform (99). A plurality of in-line skate wheels (32) are secured to the frame. An upper side of the platform has first, second and third recesses (94, 96, 98) in toe, heel and intermediate portions of the platform, respectively. A lower side of the sole (31) of the boot has first, second and third projections (80, 82, 84) in toe, heel and intermediate portions of the sole, respectively. The first, second and third projections (80, 82, 84) of the sole matingly engage the first, second and third recesses (94, 96, 98) of the platform, respectively, when the boot (22) is coupled to the frame (30). Fasteners (102, 106) secure the boot to the frame at the first, second and third recesses of the frame. A block (34) is disclosed including top and bottom sides. Sidewalls extend between the top and bottom sides. The block (34) is supported between the longitudinal rails of the frame (30) and is positioned between outer circumferences of two adjacent wheels (32). The block (34) is spaced from each of the two adjacent wheels. A fastener (102) is including for mounting the block (34) to the frame and is entirely contained between planes defined by the longitudinal rails of the frame (30).
摘要:
A tool for removing a wheel assembly from an in-line skate is provided. The in-line skate has a boot portion and a blade frame having opposing apertures and mounted to the boot portion. The wheel assembly has a wheel axle releasably mounted within the apertures ofthe blade frame and a wheel rotatably mounted on the wheel axle. The wheel axle has first and second axle ends end movable toward each other and biased away from each other. The tool comprises a flexible substantially U-shaped member having a main body portion and first and second tip ends contactable with the respective axle ends. A gripping mechanism on the main body portion grips the wheel wherein flexure of the main body portion causes the gripping mechanism to grip the wheel and the first and second tip ends to contact respective axle ends causing the first and second axle ends to move toward each other freeing the first and second axle ends from the apertures. A blade frame for an in-line skate is also provided. The blade frame comprises a mounting wall mounted to the boot portion and a pair of parallel side walls perpendicular to the mounting wall. At least one rib extends along each of the side walls. A recessed portion surrounds each of the apertures with the recessed portion sized to receive a fingertip to depress the first and second axle ends toward each other freeing the first and second axle ends from the apertures.
摘要:
An in-line skate having a generally U-shaped chassis channel and a plurality of wheels of which at least one is steerable is characterised in that a pair of elongate confronting grooves are formed in contronting inner sides of the U-shaped chassis channel and cooperate with corresponding surfaces at the end of each wheel axle such that the axle ends are secured by threaded fasteners insertable through oppositely disposed apertures in the oppositely disposed sides of the U-shaped chassis channel, with the threaded fasteners engaging into the ends of the axle. Also disclosed and claimed are a special wheel assembly, a special axle insert assembly secured within the wheel by labyrinth seal elements, a stopper assembly and a braking system.
摘要:
The invention relates to a brake device structure, in particular for skates with aligned wheels of the type comprising a boot associated to a support frame for the wheels, as well as a lever posterior of a first end which lever is associable to a part of the boot. In the structure the lever is at a second end pivoted to said frame and at an intermediate zone thereof hinged to a rack which commands means for forcing at least one brake element on to a lateral surface of one or more of the wheels. This solution obtains an effective braking operation, while keeping the wheels of both skates firmly in contact with the ground, even should the skate be travelling at a high speed.
摘要:
A roller skate with improved performance including a substantially U-shaped frame (4) supporting in-line wheels (7). The skate comprises dampers (13a,13b) that are adapted to absorb forces applied to the wheels (7) and can be deactivated by tilting the frame.
