Abstract:
An In-line-roller skate having four in-line wheels with four integral independent suspension systems, a removable boot, and a chassis structure supporting multiple brake systems, comprising:(a) a chassis system supporting and interconnecting at least four integral independent suspension systems mounted directly under the chassis structure; a front structure of the chassis supporting a front brake; a bottom-front section of the chassis structure supporting a first integral independent suspension; a bottom-middle section of the chassis structure supporting a second integral independent suspension and the front section of the second integral independent suspension is mounted in an opposite direction such that the second integral independent suspension operates in a forward motion and an opposing direction from the other independent suspension systems; a central bottom section of the chassis structure supporting a third integral independent suspension and the front section of the third integral independent suspension is mounted in an opposite direction such that the third integral independent suspension operates in forward motion and an opposing direction from other independent suspension; a middle-rear section of the chassis structure supporting a fourth integral independent suspension and the front section of the third integral suspension operates in forward motion and an opposing direction from the other independent suspension; a rear section of the chassis structure supporting a fourth integral independent suspension and the front section of the fourth integral independent suspension are mounted in an opposite direction such that the fourth integral independent suspension operates in forward motion and opposite direction from the other independent suspensions; the chassis structure interconnects and supports the removable boot, integral independent systems, and a central rolling-brake system with a plurality of removable fasteners; (b) the integral independent suspension systems comprising; a four wheeled configuration having forks pivotally mounted on axles such that the forks pivot in a forward motion and opposite directions from each other; the integral independent suspension system mounted directly under the chassis structure and attached with plurality of removable fasteners; the integral independent suspension systems supports a front and rear shock absorbers assemblies and rolling devices; said front and rear shock absorber assemblies having a shock absorber main-shaft inside a shock absorber chamber assembly; front shock absorber main-shaft supports a compression shock coils spring; the front shock absorber main-shaft having a rear and side pivotally attached to a middle-shaft disposed around the main-shaft; the front shock absorber main-shaft also having a front side engaged to a shock absorber piston; the shock absorber piston having a front side attached to a shock coils spring adjuster knob; the front shock chamber assembly contains hydraulic-fluid in a main reservoir, and a second double hydraulic-fluid parallel reservoir; the front shock chamber assembly having a front section comprising a rubber brake impact control pad attached to a removable screw and a screw cover device; the middle-shaft interconnects with the rear side of the front shock absorber main-shaft at once end the other end interconnects with a head central-trigger device, the middle-shaft interconnects to the rear of the main-shaft and to the front of the head central-trigger device through the pivot axles of the attached forks; (d) the rear shock absorber assemblies having a rear shock absorber main-shaft inside a shock chamber assembly, and the rear shock absorber main-shaft supports around split torsional shock-coils springs between a central head-trigger, and rear shock absorber main-shaft supports a plurality of ball-bearings in and a plurality of collar-retainers support torsional coils springs and forks-base-cover device; a rear shock absorber main-shaft supports fork pivot axles and ball bearings; the fork pivot axles support forks and wheels; (e) a removable boot with a supporting front and rear build-in anatomical-frame, in which the anatomical-frame supports the boot structure and the rear end of the boot structure supports and articulated boot ankle device; (f) multiple brakes systems supported by the chassis structure; the chassis structure supports a front brake device and a central rolling-brake system in which a central rolling-brake means includes rubberized ball-bearing shaft; said front brake is mounted to the chassis structure front portion, such that the front brake is not related to the front integral independent suspension system, forks or wheels; the front brake acts independently from the central rolling-brake system; the central rolling-brake is mounted under the central longitudinal portion of the chassis; at least two identical front central-brake systems are installed; (g) a main rear brake assembly is supported by the rear integral independent suspension system, said main rear brake assembly including; at least one pair of forks, connected to the front portion of the fourth integral independent suspension system through pivot axles; a rubber device for engaging the rear wheel as the said in-line roller skate superimposes pressure down in a cross position to the lock the rear wheel of an opposite in-line-roller skate; said pivot axles support a coil spring; a plurality of rubber pads under a main rear-brake platform to slow the impact of the main rear-brake fork as it returns to the original position.
