Abstract
Roller skate comprising a chassis (2) equipped with rollers (3) and a boot (1) attached removably to the chassis at four points by catching and locking. Catching and locking are achieved automatically and simultaneously at all of the attachment points using a common element (8) subject to the action of an elastic means (16). Unlocking is achieved using a lever (19) articulated to the rear of the chassis and which can be used as a handle when putting the chassis on.
Claims32
A roller skate comprising a chassis (2) having a front and rear equipped with rollers (3) and a boot (1) attached removably to the chassis at four points defining a quadrilateral, by catching and locking so as to provide a stable connection between the boot and the chassis, locking being achieved automatically when the chassis is put on, wherein automatic catching and automatic locking are achieved by respective locking portions of a catching and locking element (8;
- 35;
- 40;
- 61, 62) located at all of the four points, the catching and locking element subject to the action of at least one elastic means (16;
- 54;
- 71) for maintaining a locked position, and wherein the skate comprises an unlocking means which includes an unlocking lever (19) articulated to the rear of the chassis and acting on the catching and locking element against the action of said elastic means so as to free the boot.
A roller skate comprising a chassis (2) having a front and rear equipped with rollers (3) and a boot (1) attached removably to the chassis at four points defining a quadrilateral, by catching and locking so as to provide a stable connection between the boot and the chassis, locking being achieved automatically when the chassis is put on, wherein automatic catching and automatic locking are achieved at all of the four points using at least one catching and locking element (8;
- 35;
- 40;
- 61, 62) subject to the action of at least one elastic means (16;
- 54;
- 71) of maintaining a locked position, said chassis has at the four points V-shaped notches (4 to 7) having respective bottoms in which horizontal bars or tenons (24a, 25a;
- 33, 34;
- 36a;
- 37a, 37b) of the boot can engage and wherein the catching and locking element has nibs (11, 12;
- 45, 46;
- 64) which engage over the bars or tenons so as to maintain the bars or tenons without play in the bottom of the V-shaped notches and wherein the skate comprises an unlocking means which includes an unlocking lever (19) articulated to the rear of the chassis and acting on the catching and locking element against the action of said elastic means so as to free the boot.
A roller skate comprising a chassis (2) having a front and rear equipped with rollers (3) and a boot (1) attached removably to the chassis at four points defining a quadrilateral, by catching and locking so as to provide a stable connection between the boot and the chassis, locking being achieved automatically when the chassis is put on, wherein automatic catching and automatic locking are achieved at all of the four points using at least one catching and locking element (8;
- 35;
- 40;
- 61, 62) subject to the action of at least one elastic means (16;
- 54;
- 71) of maintaining a locked position, said catching and locking element (8) is articulated at an intermediate point about a horizontal axle (9) transverse to the chassis which passes through a slot (15) in the catching and locking element, and wherein the skate comprises an unlocking means which includes an unlocking lever (19) articulated to the rear of the chassis and acting on the catching and locking element against the action of said elastic means so as to free the boot and wherein the unlocking lever (19) acts directly on the catching and locking element and wherein when the boot is not present, the unlocking lever (19) is maintained in an approximately vertical position by the catching and locking element (8;
- 35).
