US 2008/0185816 A1 · Ski or snowboard with a means for influencing its geometry and a method of producing it

Abstract

The invention relates to a ski (2) or a snowboard in the form of a board-type gliding device (1). By reference to the width (13) of the gliding board body, at least one slot (14) is provided in its middle portion extending in the depth direction—arrow (15)—from the top face (7) of the gliding board body in the direction towards the running surface facing (10) and in its longitudinal direction extending essentially parallel with the longitudinal direction of the gliding board body. This at least one slot (14) is designed to cause a cross-sectional weakening and reduce the stiffness of the gliding board body transversely to its longitudinal direction. At least one geometry-influencing means (19) is also provided with a view to producing a cross-sectional shape or contour of the gliding board body which is variable as a function of load and/or can be manually varied. The at least one slot (14) is then faced with a bridging element (22) which is able to stretch or expand elastically, at least transversely to the longitudinal extension of the slot (14). This bridging element (22) is designed so that it prevents snow from being transferred or getting inside the slot (14) from the running surface facing (10) in the direction towards the top face (7) of the gliding board body.

Dependent claims

Ski or snowboard in the form of a board-type gliding device, with a multi-layered gliding board body comprising at least one strength-imparting top belt, at least one strength-imparting bottom belt,

at least one core disposed in between,
at least one top layer constituting the top face of the gliding board body and at least, one running surface facing constituting the bottom face of the gliding board body,
and, by reference to the width of the gliding board body, at least one slot is provided in its middle portion, which extends in the depth direction from the top face of the gliding board body in the direction towards the running surface facing and in its longitudinal direction essentially parallel with the longitudinal direction of the gliding board body in order to produce a cross-sectional weakening and reduce the stiffness of the gliding board body transversely to its longitudinal direction
and having at least one geometry-influencing means for producing a cross-sectional shape or contour of the gliding board body that is variable as a function of load and/or can be manually varied,
wherein the slot is covered by a bridging element which is elastically stretchable or able to widen at least transversely to the longitudinal extension of the slot and the bridging element is designed so that it prevents snow from passing or getting inside the slot from the running surface facing in the direction towards the top face of the gliding board body.

Method of producing a ski or snowboard in the form of a board-type gliding device, in particular for producing a multi-layered gliding board body with at least one slot extending in the longitudinal direction of the gliding board body, comprising at least the following steps:

introducing at least the following layers or materials into a hot press with at least two pressing moulds:
(i) at least one top layer constituting the top face of the gliding board body,
(ii) at least one layer for forming a strength-imparting top belt,
(iii) at least one curable foamed plastic forming the core of the gliding board body and/or at least one prefabricated core component,
(iv) at least one layer for forming a strength-imparting bottom belt,
(v) at least one running surface forming the bottom face of the gliding board body
(vi) at least one adhesive layer in the form of a hot-melt adhesive and/or poly-urethane foam
activating the heat pressing operation by means of the hot press in order to join the layers introduced into the hot press by adhesive to form the multi-layered gliding board body,
wherein the running surface facing is prepared as follows prior to being introduced into the hot press:
at least one slot is cut which, by reference to the width of the running surface facing is positioned in the middle portion of the running surface facing and extends in the longitudinal direction of the running surface facing;
preparing and providing an elastically stretchable or expandable bridging element with dimensions that are the same as, bigger than or slightly smaller than the slot cut into the running surface facing;
disposing the elastically stretchable or expandable bridging element in the slot or above the slot of the running surface facing.
