Abstract
A frame for a sports article, especially a frame for a roller skate, including a front upper portion provided to receive the front portion of a boot, and a rear upper portion provided to receive the rear portion of a boot. The front upper portion and the rear upper portion are part of the same planar upper surface. The frame further includes two cylindrical holes provided to receive two fixing elements, the holes extending in the longitudinal plane of the frame and their respective axes being spaced from one another by a value E of between about 164 mm and 170 mm, more particularly equal to about 167 mm. Moreover, a substantially cylindrical cavity centered on the axis of the cylindrical hole is provided in the upper surface. The invention is also directed to a line of boots for a roller skate and to a line of frames therefor.
Claims11
A line of frames for roller skates, said line including at least a shortest frame and a longest frame, each said frame of the line including:
- two parallel vertical flanges between which a plurality of in-line wheels can be positioned;
- a planar front upper surface in the middle of which a first cavity is located, a first cylindrical hole having an axis perpendicular to said front upper surface provided in said first cavity;
- a rear upper surface, coplanar with said front upper surface, in the middle of which a second cavity is located, a second cylindrical hole having an axis parallel to the axis of said first cylindrical hole and spaced therefrom by about 167 millimeters;
- wherein, for each said frame of the line:
- said plurality of in-line wheels are positioned between said two parallel vertical flanges;
- and
- said plurality of in-line wheels includes two central wheels, said two central wheels being spaced apart by the same distance within the line of frames.
A line of roller skates, said line including a first pair of roller skates having a shortest frame and a second pair of roller skates having a longest frame, each said frame of line of roller skates including:
- two parallel vertical flanges between which a plurality of in-line wheels are positioned;
- a planar front upper surface in the middle of which a first cavity is located, a first cylindrical hole having an axis perpendicular to said front upper surface provided in said first cavity;
- a rear upper surface, coplanar with said front upper surface, in the middle of which a second cavity is located, a second cylindrical hole having an axis parallel to the axis of said first cylindrical hole and spaced therefrom by between about 164 millimeters and 170 millimeters
- wherein, for each said frame of said roller skate of said line of roller skates:
- said plurality of in-line wheels is positioned between said two parallel vertical flanges;
- said plurality of in-line wheels includes two central wheels, said two central wheels being spaced apart by the same distance within the line of frames.
A line of frames for roller skates comprising:
- a plurality of at least four sizes of frames, said plurality of frames including a shortest frame and a longest frame;
- each said frame of said plurality of frames including:
- two flanges between which a plurality of in-line wheels can be positioned;
- a front upper surface extending between said two flanges, said front upper surface having a first cavity and a first hole within said first cavity, said first hole having an axis intersecting said front upper surface;
- a rear upper surface extending between said two flanges, said rear upper surface having a second cavity and a second hole within said second cavity, said second hole having an axis intersecting said rear upper surface;
- said axes of said first and second holes being substantially parallel and being spaced apart by a distance that varies within said plurality of frames by no greater than about six millimeters.
A line of roller skates comprising:
- a plurality of at least four sizes of roller skates including a first roller skate having a shortest frame and a second roller skate having a longest frame;
- each said frame of said plurality of at least four roller skates including:
- two flanges between which a plurality of in-line wheels can be positioned;
- a front upper surface extending between said two flanges, said front upper surface having a first hole and a first connector extending through said first hole connecting a boot to said frame, said first hole having an axis intersecting said front upper surface;
- a rear upper surface extending between said two flanges, said rear upper surface having a second hole and a second connector extending through said second hole connecting the boot to said frame, said second hole having an axis intersecting said rear upper surface;
- said axes of said first and second holes being spaced apart by a distance that varies within said plurality of skates by no greater than about six millimeters.
