Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
172 words
An articulated and steerable snow sled comprising: a. flat boards connected to each other forming said sled; b. a steering mechanism provided on the front board of said flat boards for steering said sled; c. a braking system connected to the rear board of said flat boards for providing the braking of said sled; d. handle elements provided on the lateral sides of each flat board for providing gripping means for the occupants of the sled; e. a cable system connected to said steering mechanism and to the rear edge of said rear board, said cable system running along the lateral sides of said boards and passing through said handle elements, said cable system providing under the movement of said steering mEchanism the horizontal pivoting of said boards with respect to each other; f. resilient members connected to the forward part of each board and to said handle elements respectively in order to provide the re-alignment of the pivoted boards when said steering mechanism is released by the conductor of the sled.
Claim 2
Dependent Claim
172 words
An articulated and steerable snow sled comprising: a. flat boards connected to each other forming said sled; b. a steering mechanism provided on the front board of said flat boards for steering said sled; c. a braking system connected to the rear board of said flat boards for providing the braking of said sled; d. handle elements provided on the lateral sides of each flat board for providing gripping means for the occupants of the sled; e. a cable system connected to said steering mechanism and to the rear edge of said rear board, said cable system running along the lateral sides of said boards and passing through said handle elements, said cable system providing under the movement of said steering mEchanism the horizontal pivoting of said boards with respect to each other; f. resilient members connected to the forward part of each board and to said handle elements respectively in order to provide the re-alignment of the pivoted boards when said steering mechanism is released by the conductor of the sled.
Claim 3
Dependent Claim
17 words
A snow sled according to claim 1, said sled being composed of a plurality of flat boards.
Claim 4
Dependent Claim
21 words
A snow sled according to claim 2, wherein said handle elements are positioned at the rearward part of each flat board.
Claim 5
Dependent Claim
102 words
A snow sled according to claim 2, wherein the forward part of each flat board is provided with a transverse bar, each transverse bar having at least two curved slots, each slot being located at one extremity of said transverse bar, and wherein the rear edge of each board is provided with two pins corresponding to said slots, said pins being inserted inside said slots in such a way as to prevent the vertical separation of two adjacent boards and as to limit the horizontal pivoting of said boards with respect to each other, thus preventing any uncontrollable pivoting of these boards.
Claim 6
Dependent Claim
71 words
A snow sled according to claim 2, wherein each board is provided on its bottom surface resting on the snow with runner elements, said runner elements being formed as a corrugated plate, and wherein each board is further provided with two lateral runners each located under the extreme lateral edge of a board, said runner elements and said lateral runners preventing any undesirable sliding of the sled into right or left.
Claim 7
Dependent Claim
68 words
A snow sled according to claim 2, wherein said braking system comprises two blade elements connected by means of pivots to the rear edge of the rear board, and wherein there is the provision of lever means connected to said blade elements and positioned adjacent said handle elements of said rear board for permitting the manual actuation of the blade elements by the occupant of said rear board.
Claim 8
Dependent Claim
49 words
A snow sled according to claim 2, wherein said resilient members are made of two spring blades, V-shaped, one end of each spring blade being connected to said handle element and the other end of the same spring blade being connected to a pivot connecting two consecutive adjacent boards.
Claim 9
Dependent Claim
32 words
A snow sled according to claim 2, wherein pulleys are provided on the front board of said flat boards and around which said cable passes before being wound around said steering mechanism.
Claim 10
Dependent Claim
31 words
A snow sled according to claim 2, wherein the front board is provided with an outwardly curved forward edge, which curved edge is connected to said steering mechanism through a sleeve.
Claim 11
Dependent Claim
30 words
A snow sled according to claim 2, wherein two of the flat boards connected to each other are provided with folding means, said means providing the folding of the sled.
Claim 12
Dependent Claim
30 words
A snow sled according to claim 2, wherein said handle elements are provided with slots to permit to the hands of the sled occupants to firmly grip said handle elements.
Claim 13
Dependent Claim
34 words
A snow sled according to claim 4, wherein said handle elements and said transverse bars are provided with longitudinal holes to permit to said cable to pass through said holes and be guided thereby.
Claim 14
Dependent Claim
24 words
A snow sled according to claim 7, wherein said pivot connecting two adjacent boards is countersunk into a hole provided on said transverse bar.
Claim 15
Dependent Claim
16 words
A snow sled according to claim 4, wherein said pins are countersunk into said curved slots.
Claim 16
Dependent Claim
25 words
A snow sled according to claim 5, wherein said runner elements and said two lateral runners are located at the rear part of each board.
