Abstract
Abstract A pre-skiing exercise device which permits body and leg movements similar to those performed when turning (Christiania-like) to the right and to the left during a downhill run. The device comprises two support bars (2) in parallel, side-by-side relation and arranged for attachment of ski-boots, either directly or through the respective ski (4). The rear sections of the support bars (2) slidably bear on an inverted V-shaped supporting cross member (6), and at an intermediate position on an articulated bar-supporting device (7), in which each of the bars (2) can rock independently of the other about an associated horizontal axis of inclination (X) transversal thereto, and both bars (2) can simultaneously perform concordant equal angular movements around associated upstanding axes of rotation (Y), which are vertical or preferably inclined rearwardly toward the inverted V rear supporting cross member (6).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
161 words
A pre-skiing exercise device comprising two support bars (2) in parallel, side by side relation, and provided with means (3) for attachment thereto of a ski-boot, said support bars (2) having rear end sections slidably bearing on an inverted V rear supporting cross member (6), and supported at an intermediate position by an articulated bar-supporting device (7) on which each of said bars (2) can rock independently of the other bar about an associated horizontal axis of inclination (X) transversal thereto, both bars being allowed to simultaneously perform coordinated equal angular movements about associated upstanding axes of rotation (Y), said bar-supporting device being pivotally connected by means of a transverse horizontal pivot (11), coinciding with the axis of inclination (X), to a bar-carrying head (10) which is rotatably mounted onto a fixed post (9, 109) coinciding with the axis of rotation (Y), the two bar-carrying heads (10) being interconnected so as to be caused to simultaneously perform coordinated equal rotational movements.
Claim 2
Dependent Claim
161 words
A pre-skiing exercise device comprising two support bars (2) in parallel, side by side relation, and provided with means (3) for attachment thereto of a ski-boot, said support bars (2) having rear end sections slidably bearing on an inverted V rear supporting cross member (6), and supported at an intermediate position by an articulated bar-supporting device (7) on which each of said bars (2) can rock independently of the other bar about an associated horizontal axis of inclination (X) transversal thereto, both bars being allowed to simultaneously perform coordinated equal angular movements about associated upstanding axes of rotation (Y), said bar-supporting device being pivotally connected by means of a transverse horizontal pivot (11), coinciding with the axis of inclination (X), to a bar-carrying head (10) which is rotatably mounted onto a fixed post (9, 109) coinciding with the axis of rotation (Y), the two bar-carrying heads (10) being interconnected so as to be caused to simultaneously perform coordinated equal rotational movements.
Claim 3
Dependent Claim
25 words
Device according to claim 1, wherein the upstanding axes of rotation Y of said support bars (2) are inclined rearwardly toward said cross member (6).
Claim 4
Dependent Claim
14 words
Device according to claim 1, wherein said cross member (6) is adjustable in height.
Claim 5
Dependent Claim
18 words
Device according to claim 1, wherein said cross member is replaceable by other cross members having different configurations.
Claim 6
Dependent Claim
45 words
Device according to claim 1, wherein both bar-carrying heads (10) have eccentric extensions (12) in engagement with opposite ends of a swingable connection lever (13) intermediately fulcrumed about a pivot (14) which is parallel to the axes of rotation (Y) of said bar-carrying heads (10).
Claim 7
Dependent Claim
23 words
Device according to claim 1, wherein both bar-carrying heads (10) are made integral with pulleys (15) interconnected by means of a belt (16).
Claim 8
Dependent Claim
32 words
Device according to claim 1, wherein both bar-carrying heads (2) have at least two radially extending parallel arms (17) pivotally connected through a transverse rod (18), whereby an articulated parallelogram is formed.
Claim 9
Dependent Claim
31 words
Device according to claim 1, comprising abutment stop members (19, 21, 23) for restraining in either direction the angular movement of said support bars (2) about the axes of roation (Y).
Claim 10
Dependent Claim
21 words
Device according to claim 8, wherein said stop abutment members (19) are provided at the ends of said cross member (6).
Claim 11
Dependent Claim

Claim 12
Dependent Claim
39 words
Device according to claim 7, comprising abutment stop members (23) at the ends of a cross bar (20) which is fixed between said two posts (9), and cooperating with said radially extending arms (17) of said bar-carrying heads (10).
Claim 13
Dependent Claim
32 words
Device according to claim 1, wherein, on its end opposite to the inverted V supporting cross member (6), said device is provided with perforated support means (24) for the reception of ski-poles.
Claim 14
Dependent Claim
37 words
Device according to claim 1, wherein on its end opposite to the inverted V supporting cross member (6), said device is provided with perforated support means (24) for the reception of an inverted U-shaped handle bar (25).
