Abstract
A binding unit (1) for gliding boards, such as snowboards, is composed of two support plates (2) and (3) which can be independently telescoped along the longitudinal axis of a boot. Each support plate is slidingly guided along this longitudinal axis in a guide element (4 and 5, respectively). Sole-holding shackles (7 and 9) are held laterally. The support plates are form-lockingly held in a position set to the boot length by starting from a central fixing element (6).
Claims18
An adjustable length binding unit for securing a boot to a gliding board comprising:
- forward and rear sole-holding means;
- an opening device associated with at least one of said sole-holding means;
- two independently slidable support plates, oppositely disposed along the longitudinal axis of the binding unit, for holding the forward and rear sole-holding means respectively;
- each of said support plates having an extension which is disposed laterally and runs parallel to the longitudinal axis of the support plate and, in each case, is directed toward the opposite support plate such that said extensions lie next to each other;
- two spaced apart guide elements, one for each of said support plates, for slidably guiding each respective support plate independently of the other said support plate and in direction parallel to said longitudinal axis of the binding unit;
- means for connecting said guide elements to the gliding board comprising a base plate formed on each of said guide elements and removably and adjustably mounted to the gliding board;
- a single fixing element, operable without the aid of tools and centrally disposed along the longitudinal axis of the binding unit, for selectively engaging both of said extensions of said independently slidable support plates simultaneously, whereby engagement of said extensions by said fixing element fixes the position of said extensions along the longitudinal axis of the binding unit and disengagement therefrom allows each of said extensions to be manually, independently, and slidably displaced along the longitudinal axis of the binding unit so that variable heel and toe spans from said fixing element are establishable;
- and means for securing said fixing element to the gliding board.

- forward and rear sole-holding means;
- an opening device associated with at least one of said sole-holding means;
- two independently slidable support plates, oppositely disposed along the longitudinal axis of the binding unit, for holding said forward and rear sole-holding means respectively, each of said support plates having an extension which is disposed laterally and runs parallel to the longitudinal axis of the support plate and, in each case, is directed toward the opposite support plate such that said extensions lie next to each other;
- two spaced apart guide elements, one for each of said support plates, for slidably guiding each respective support plate independently of the other said support plate and in a direction parallel to said longitudinal axis of the binding unit;
- each of said guide elements including a central longitudinal groove-shaped recess having a pair of side walls extending therealong;
- means for connecting said guide elements to the gliding board comprising a base plate formed on each of said guide elements and removably and adjustably mounted to the gliding board;
- a single fixing element, operable without the aid of tools and centrally disposed along the longitudinal axis of the binding unit, for selectively engaging both of said extensions of said independently slidable support plates simultaneously, whereby engagement of said extensions by said fixing element fixes the position of said extensions along the longitudinal axis of the binding unit and disengagement therefrom allows each of said extensions to be manually, independently, and slidably displaced along the longitudinal axis of the binding unit so that variable heel and toe spans from said fixing element are establishable;
- and
- means for securing said fixing element to the gliding board.
- a support plate cover for each of said support plates being detachably mounted thereto;
- a central cover detachably mounted to said fixing element;
- and
- wherein each of said support plates includes, at the end remote from said fixing element, two slider edges disposed parallel to the longitudinal axis of said support plates, said pair of side walls of said groove-shaped recess being slidingly engaged by a corresponding pair of slider edges on the respective support plate.
