Abstract
Description
- This application is a continuation-in-part of U.S. Ser. No. 09/166,323 filed Oct. 15, 1998 entitled “Raised Platform for Ski Binding” the disclosure of which is incorporated herein by reference.
- The present invention relates to a raised platform for a ski binding, intended to be mounted on a ski by means for binding to the ski and by a longitudinal guide and vertical retention means in its front and rear zones.
- With a view to improving skiability, the current trend is toward the mounting of ski bindings on raised platforms. These platforms are generally fixed to the ski in their front zone or in their rear zone, and guided longitudinally and retained vertically in the opposite zone. This method of connection to the ski making it possible to provide some degree of unclamping of the ski in its central zone, that is to say to allow the ski to retain its flexibility, in other words to flex in the central zone so as to maintain contact with the snow when skiing through hollows or over bumps. So as not to counter the natural dynamics of the ski in flexion and torsion, it has proved preferable to bind the raised platform to the ski in its central zone, and to allow the front and rear zones to move relative to the ski. In an embodiment described in U.S. Pat. No. 5,413 371, the raised platform consists of two high-density foam blocks fixed respectively to two platforms which are mounted “floating” on the ski and are connected by a rigid metal plate, fixed to the ski by screws at its center. The high-density foam parts damp vibrations.
- The object of the present invention is to further improve the unclamping of the ski and to simplify the manufacture of the raised platform.
- To this end, the raised platform according to the invention is one which is made of moldable synthetic material and is narrowed in its central zone so as to be flexible in this zone.
- The narrowing of the synthetic material in the central zone of the raised platform makes it possible to obtain a very high degree of flexibility in this zone and, consequently, virtually complete unclamping of the ski in its central part.
- The narrowing is preferably formed by removing material from the lower face of the platform, so that the narrowing of the central zone forms at least one hollow in the lower face of the platform.
- Also preferably, the raised platform has two narrowed sections, to the front and to the rear of a relatively narrow bearing zone through which the means for binding the platform to the ski pass.
- According to a preferred embodiment of the invention, the hollows are at least partially filled with a flexible and elastic or elastomer material, preventing the entry of snow and the formation of ice, and forming a means for damping vibrations. This flexible and elastic material may be cut out extensively, the essential fact being that it forms bands which adjoin the edges of the raised platform to form a barrier for the snow.
- The appended drawing represents an embodiment of the raised platform according to the invention by way of example.
- FIG. 1 is a side view of the raised platform when mounted on a ski.
- FIG. 2 is a plan view of the raised platform, without the means for connecting it to the ski.
- FIG. 3 is a bottom view of the central zone of the raised platform.
- FIG. 4 is a view in section on IV-IV of FIG. 1.
- FIG. 5 is a view in section on V-V of FIG. 1.
- FIG. 6 is a view in section on VI-VI of FIG. 1.
- FIG. 7 represents a first alternative embodiment in a view similar to FIG. 1.
- FIG. 8 represents a second alternative embodiment in a view similar to FIG. 1.
- FIG. 9 represents a third alternative embodiment in a view similar to FIG. 1.
- FIG. 10 is a partial view of an alternative embodiment having a flexion indicator.
- FIG. 11 is a side, view of a fourth alternative embodiment of the raised platform when mounted on a ski.
- FIG. 12 is a plan view of the raised platform shown in FIG. 11, without the means for connecting it to the ski.
- The raised
platform 1, represented in FIG. 1 on aski 2, essentially consists of a piece of molded synthetic material, for example a polyamide filled with glass fibers. It consists of twosupports central zone 5. This narrowed central zone being itself divided into two narrowed zones located to the front and to the rear of a narrowtransverse band 6 which has the same thickness as the supports 3 and 4 and bears directly on the ski. The raised platform also has, in plan, a transverse width reduction in its central zone, this width reduction further enhancing the flexibility of this zone. The narrowed part forms twohollows hollows elastic material hollows - In this embodiment, the
central band 6 has twoholes 11 for binding the raised platform to the ski by means of twoscrews 12.Rectangular holes 13 which have acountersink 14 and in whichpins 15 fixed to the ski are engaged, pass through thesupports supports platform 1 also has a number ofholes 16 which are intended to accommodate the binding screws of the elements of the ski binding in various positions. - A number of variants may, of course, be made to the embodiment which has been described and represented.
- According to a variant represented in FIG. 7, the
central bearing band 6 is replaced by one ormore struts 17. - In a variant represented in FIG. 8, the flexible and
elastic material supports - According to the variant represented in FIG. 9, the
supports end zones zones zones elastic material material - The
materials - The raised platform could also have a means for displaying its displacement relative to the ski when the ski flexes. An illustrative embodiment of this means is represented in FIG. 10. It consists of an
index 20 located on the platform beside one of theholes 13, and ascale 21 located on thepin 15 which is engaged in this hole. This figure also shows the clearance d between thepin 15 and thehole 13, this allowing the clearance ski to flex. - A further variation is found in FIGS. 11 and 12 which as distinct from prior embodiments has the
center band 6 removed. Thecentral zone 5 is now a solid pieceabsent holes 11 forscrews 12. - Accordingly, there are no fasteners in the
central zone 5 and with the reduced mass by the elementation ofband 6, provides for increased flexibility in thecentral zone 5.
