DESCRIPTION:
BRIEF SUMMARY
RELATED APPLICATIONS
This application is based under 35 USC 371 on, and claims the benefit of PCT/EP95/00540, filed Feb. 14, 1995, published as WO95/21663 Aug. 17, 1995.
BACKGROUND OF THE INVENTION
1. Technical Field
The invention relates to a sliding body, in particular a ski or runner, as they are usable with apparatus and vehicles, particularly for snow and ice, but for water sports also.
2. Description of the Related Art
Essential for good sliding properties as well as for directional stability and steering ease or manoeuvrability resp. and also for durability under shock-like and vibrating stresses is the oscillating response of the body or its external parts getting in interaction with the sliding medium. According to usual technique substantially only he oscillating response in very low frequency ranges is taken into consideration. In this way spacious or macroscopic phenomina can be taken into account which, however, left open desires for various optimizations up to now.
Therefore, the task of the invention is the creation of sliding bodies further improved with regard to the aforesaid points. The basic idea of the solution according to the invention here is taking into account medium and higher frequency ranges or characteristic frequencies and above all, the resonance spectra in those ranges.
To the the task as set above the solution according to the invention is defined by the features of the patent claim 1 or of the subordinate claims. The features of the dependent claims present inventively essential integral parts or further developments resp.. The subject matters thereof are practicable each alone, however, with special advantages in the various possible combinations.
The basic idea of the invention consists in the realization of at least one vibration-reactive subdivisional structure with at least one sequence of distinct spatial, superficial or linear region, which present at least one vibration parameter, particularly a local spatial or suberficial mass density, resistance to bending deformation or dampening, which is dimensioned or distributed differently in relation to at least one adjacent region or within the region itself. With advantage there is provided at least one sequence of a plurality of distinct regions with differently dimensioned or distributed vibration parameters. Further an essential feature consists in providing at least one periodic sequence of distinct regions with differently dimensioned or distributed vibration parameters. In particular at least one sequence of distinct regions with differently dimensioned or distributed vibration parameters is considered, which sequence extends along a surface of the sliding body, and which e.g. may comprise at least one sequence of distinct regions extending substantially in the interior of the sliding body and having differently dimensioned or distributed vibration parameters, particularly at least one sequence of distinct regions having differently dimensioned or distributed vibration parameters and extending multidimensionally or in a plurality of spatial or superficial directions.
In further developing the invention at least partially different distance sequences between the distinct regions and/or different vibration parameter variations from region to region are assigned to the different dimensions or spatial or superficial directions resp., in which a sequence of distinct regions with differently dimensioned or distributed vibration parameters extends, in which context particularly said distinct regions with differently dimensioned or distributed vibration parameters are arranged serially or grid-like in at least one area, particularly within a surface section of the sliding body.
The distinct regions of different vibration parameters may be arranged in a distribution in at least one surface section and/or at least one wall section of a cavity of the sliding body or along at least one edge of the sliding body. In a further variation the distinct spatial, superficial or linear regions comprise at least one section with v
