ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an interface device between a ski and the elements for retaining a boot on the ski.
The invention also relates to an assembly for retaining a boot on a ski, the assembly including the interface device as well as to a ski in combination with the interface device.
2. Description of Background and Relevant Information
In accordance with the international patent application published as No. WO 96/35488, an interface device is known which includes an elongated plate on which both the retaining elements are mounted. The plate is raised with respect to the ski. It is connected to the ski in its central portion via two projections whose spacing can be adjusted. In addition, a shock-absorbing element is wedged between each of the ends of the plate and the ski.
Such a device produces a greater concentration of pressure in the central zone of the ski. In addition, since both retaining elements are mounted on the same plate that is separate from the beam of the ski, the ski is freed from the stresses generated by the boot retaining elements.
This interface device provides satisfactory results; indeed, it allows the ski to bend naturally, and the ski follows its trajectory along a normal curve while turning.
SUMMARY OF THE INVENTION
An object of the invention is to propose an interface of the aforementioned type which further improves the natural bending of the ski especially while turning, and which makes the ski's steering smoother when there are alternating wide and narrow turns.
Another object of the invention is to propose an interface device that provides greater freedom to the ski in the area of its sliding surface.
Other objects and advantages of the invention will become apparent from the following description.
The interface device according to the invention includes front and rear platforms having mounting zones for the front and rear retaining elements, such platforms being raised with respect to the surface defined by the upper surface of the ski. The platforms are supported by a cradle whose length is reduced with respect to the volume of the platforms and provided to be affixedly connected to the ski, in that each platform is connected to the cradle via a bearing journal, and both platforms are connected to each other via a non-extensible connection located above the level of the journals.
The assembly for retaining a boot on a ski according to the invention includes a front retaining element and a rear retaining element. The retaining elements are borne by front and rear platforms, the platforms being supported by a cradle, each platform being connected to the cradle about a bearing journal, and the platforms being connected to each other via a nonextensible connection.
The ski according to the invention includes an interface device or a retention assembly such as that previously described.
