Gliding board
The present invention relates to a gliding board for cross-country skiing, intended to receive a shoe fastener (F) including an upper face, a lower face and side ridges, characterized in that at least one of the side ridges of the board is provided with a series of notches ( 11 ) whereof each rim ( 11 a ) defines, on the one hand, a transverse stop face ( 12 ) making it possible to stop the board in the backwards direction, and on the other hand, a longitudinal connecting face ( 13 ) between the notches ( 11 ) allowing forward gliding.
1. A gliding board for cross-country skiing intended to receive a shoe fastener, the gliding board comprising:
an upper face,
a lower face, and
side ridges,
wherein at least one of the side ridges of the board is provided with a series of adjacent notches separated by rims,
wherein each notch is defined by
a front side face forming a transverse face that is configured to stop the board in the backwards direction, and
a rear side face forming a longitudinal face configured to allow forward gliding,
wherein the front side face and rear side face are asymmetrical relative to a transverse axis of the board.
2. The gliding board according to claim 1 ,
wherein the transverse face of at least one or the notches is inclined toward the transverse axis and toward the rear of the board with an angle between 0° and 15° relative to said transverse axis.
3. The gliding board according to claim 1 ,
wherein the longitudinal face of at least one of the notches has an angle (α) between 60° and 85° relative to the transverse axis of the board.
4. The gliding board according to claim 1 ,
wherein the transverse face of each notch has an angle of 90° relative to a corresponding longitudinal face.
5. The gliding board according to claim 1 ,
wherein each of the side ridges of the board is provided with a series of said notches, said notches extending over at least part of a zone of the board configured to receive the shoe faster.
6. The gliding board according to claim 1 ,
wherein the rims are vertical.
7. The gliding board according to claim 1 ,
wherein, on each side ridge, the intersections of the rims with the lower face are positioned on a same concave curve.
8. The gliding board according to claim 1 ,
wherein the longitudinal faces between adjacent notches of a same series are beveled toward an inside of the board.
9. The gliding board according to claim 1 ,
wherein the notches have a depth between 2 and 10 mm.
10. The gliding board according to claim 1 ,
wherein the apices of two consecutive rims are spaced apart by at least 20 mm.
11. The gliding board according to claim 1 ,
wherein the notches extend over a height greater than or equal to half the thickness of the side ridge of the board.
12. The gliding board according to claim 1 ,
wherein the series of notches extend over at least 300 mm of the side ridge and wherein the series of notches are centered on a positioning of the shoe faster.
13. The gliding board according to claim 1 ,
wherein the board is made up of a core positioned between the upper and lower faces and wherein the board further comprises a sole plate on the lower face extending from one lateral ridge to the other.
14. The gliding board according to claim 13 ,
wherein the core comprises partially hollowed out zones.
15. The gliding board according to claim 13 ,
wherein the sole plate extends to the side ridges of the board where the series of notches are formed.
16. The gliding board according to claim 13 ,
wherein said lower face is provided with at least one longitudinal slot intended to receive a backstop skin.
17. The gliding board according to claim 13 ,
wherein said lower face is provided with scales.
18. The gliding board according to claim 1 ,
wherein the apices of two consecutive rims are spaced apart by at least 30 mm.
