Door device

A door device (1) adapted to provide a watertight condition against an external surface, the door device (1) comprising:

• a main support surface (2), defining a main area (2a);
• a main spar (10) adapted to be moved in an activation direction (D) between an inactive position and a watertight position;
• a first main closing element (3) comprising a wedged end (31) with a first closure point (32) located in an acute vertex of said wedged end (31),
• a second main closing element (4) comprising a wedged end (41) with a second closure point (42) located in an acute vertex of said wedged end (41), said first and second closure points (32, 42) defining a closure gap, which is the distance between said first and second closure points (32, 42);
• first connecting elements (5), each having a first end (51) and a second end (52), each first connecting element (5) being hingeably attached in the first end (51) to the main spar (10);
• second connecting elements (6), each having a first end (61) and a second end (62), each second connecting element (6) being hingeably attached in the first end (61) to the second end (52) of one first connecting element (5) and being hingeably attached in the second end (62) to the first main closing element (3);
• third connecting elements (7), each having a first end (71) and a second end (72), each third connecting element (7) being hingeably attached in the first end (71) to the main spar (10);
• fourth connecting elements (8), each having a first end (81) and a second end (82), each fourth connecting element (8) being hingeably attached in the first end (81) to the second end (72) of one third connecting element (7) and being hingeably attached in the second end (82) to the second main closing element (4);
• a plurality of primary guiding elements (91, 92), each one being attached to the main support surface (2), in such a way that
• each one of the second connecting elements (6) is in contact with one of a first group of primary guiding elements (91) which are oriented forming a first primary guiding angle (δ1) with respect to the activation direction (D) in clockwise direction, and
• each one of the fourth connecting elements (8) is in contact with one of a second group of primary guiding elements (92), which are oriented forming a second primary guiding angle (δ2) with respect to the activation direction (D) in counterclockwise direction;
• a transversal element (11) comprising an auxiliary closing wedge (111) with sides, two of the sides forming first and second wedge angles (β1, β2) respectively with respect to the activation direction (D) and other side being the ground side;
• a first secondary guiding element (93), and a second secondary guiding element (94), the secondary guiding elements (93, 94) being adapted to guide the tranversal element (11), the tangent to each point of the first secondary guiding element (93) forming a first secondary guiding angle (α1) with respect to the activation direction (D) in counterclockwise direction and the tangent to each point of the second secondary guiding element (94) forming a second secondary guiding angle (α2) with respect to the activation direction (D) in clockwise direction;
• wherein
• in the inactive position of the main spar (10), the first and second main closing elements (3, 4) are located within the main area (2a);
• along the movement of the main spar (10) between the inactive position and the watertight position, the movement of each second connecting element (6) is limited by one of the first group of primary guiding elements (91) to the direction of said primary guiding element (91) and the movement of each fourth connecting element (8) is limited by one of the second group of primary guiding elements (92) to the direction of said primary guiding element (92), making the first and second main closing elements (3, 4) exit the main area (2a);
• when the main spar (10) is in the watertight position, the closure gap is equal to the length of the ground side of the auxiliary closing wedge (111);
• the secondary guiding elements (93, 94) are adapted to guide the transversal element (11) so that the auxiliary closing wedge (111) exits the main area to abut both the wedged end (31) of the first main closing element (3) which forms a first closing angle with respect to the activation direction (D) which is equal to the first wedge angle (β1), and the wedged end (41) of the second main closing element (4) which forms a second closing angle with respect to the activation direction (D) which is equal to the second wedge angle (β2);
• and
• the first secondary guiding angle (α1) is lower than, or equal to, the first wedge angle (β1) and the second secondary guiding angle (α2) is lower than, or equal to, the second wedge angle (β2).
