Abstract
Abstract Ski with an upper layer, a lower layer, and optionally an intermediate layer. The ski has a central core made of a hard material, especially a hard wood, and has a running surface and laterally extending edge protectors. At least one of the two outer surfaces of the core has one or more recesses for matching damper elements made of an elastic material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A ski comprising: a composite multilayer structure with an upper layer, a lower layer, and at least one core of a hard material arranged between respective layers, and edge protection means along the lateral sides of said structure, said lower layer being formed with a running surface, and at least one damper element of an elastic material recessed in at least one outer surface of said core adjacent a corresponding one of said layers, said edge protection means including lateral walls which are discontinuous to allow mounting of the respective damper element thereat.
Claim 2
Dependent Claim
93 words
A ski comprising: a composite multilayer structure with an upper layer, a lower layer, and at least one core of a hard material arranged between respective layers, and edge protection means along the lateral sides of said structure, said lower layer being formed with a running surface, and at least one damper element of an elastic material recessed in at least one outer surface of said core adjacent a corresponding one of said layers, said edge protection means including lateral walls which are discontinuous to allow mounting of the respective damper element thereat.
Claim 3
Dependent Claim
27 words
The ski according to claim 1 wherein at least two damper elements are positively secured flush with the respective outer surfaces, and are spaced from one another.
Claim 4
Dependent Claim
33 words
The ski according to claim 1 wherein said core is comprised of several parts, and wherein at least one core part has a portion made of the same material as said damper element.
Claim 5
Dependent Claim
19 words
The ski according to claim 3 wherein at least one tip of a core part is a damper element.
Claim 6
Dependent Claim
16 words
The ski according to claim 1 wherein said damper element has an approximately rectangular cross section.
Claim 7
Dependent Claim
16 words
The ski according to claim 1 wherein said damper element has an approximately sectoral cross section.
Claim 8
Dependent Claim
27 words
The ski according to claim 1 wherein said damper element extends at an angle of approximately 70° with respect to the longitudinal central axis of the ski.
Claim 9
Dependent Claim
57 words
The ski according to claim 1 wherein in at least one outer wall of said core at least one aperture is formed which is sectoral when viewed in plan view and a chord thereof is coincidental with the lateral longitudinal edge of said core, said damper element having matching sectoral shape in conformity with said sectoral aperture.
Claim 10
Dependent Claim
13 words
The ski according to claim 8 wherein said damper element is a plate.
Claim 11
Dependent Claim

The ski according to claim 1 wherein at least one portion of said damper element (9,16) has an arcuate profile.
Claim 12
Dependent Claim
21 words
The ski according to claim 10 wherein said arcuate profile of said damper element (9) extends vertically relative to said layers.
Claim 13
Dependent Claim
21 words
The ski according to claim 10 wherein said arcuate profile of said damper element (16) extends parallel relative to said layers.
Claim 14
Dependent Claim
