Guide for a liftable sliding leaf
A guide ( 10 ) for a liftable sliding leaf comprises at least two guide bars ( 14, 16 ), a first bar ( 14 ) of which can be connected movably to a support ( 24 ), fixed with respect to the leaf, and a second bar ( 16 ) can be connected integrally to a top part ( 12 ) of the leaf ( 11 ) so that both the bars ( 14, 16 ) are movable in a vertical plane.
1. A guide for liftable sliding leaf, the guide comprises:
at least two guide bars, a first bar of the at least two guide bars being able to be connected movably to a fixed support bar, the liftable sliding leaf being movable with respect to the fixed support bar, and a second bar of the at least two guide bars being able to be connected to a top part of the liftable sliding leaf and being movable integrally with said liftable sliding leaf;
both said first and second bars being liftable in a vertical plane from a first position, in which the liftable sliding leaf rests on the ground and movement thereof is locked, to a lifted position, in which the liftable sliding leaf is free to slide laterally,
wherein the second bar is a rigid member, elongated along the whole top edge of the liftable sliding leaf.
2. The guide according to claim 1 , comprising a lever mechanism or pulling and lifting mechanisms, connected to the first bar and adapted to move said first bar.
3. The guide according to claim 2 , wherein the first bar carries a first magnet and the second bar carries a second magnet, the first and second magnets positioned as a pair of magnets facing each other.
4. The guide according to claim 2 , wherein one guide bar of the first bar or the second bar of the at least two guide bars carries at least one rolling element slidable on the other guide bar of the first bar or the second bar.
5. The guide according to claim 4 , wherein the at least one rolling element, carried by the one guide bar, is slidable on a rail, carried by the other guide bar.
6. The guide according to claim 1 , wherein the first bar carries a first magnet and the second bar carries a second magnet, the first and second magnets positioned as a pair of magnets facing each other.
7. The guide according to claim 1 , wherein one guide bar of the first bar or the second bar of the at least two guide bars carries at least one rolling element slidable on the other guide bar of the first bar or the second bar.
8. The guide according to claim 7 , wherein the at least one rolling element, carried by the one guide bar, is slidable on a rail, carried by the other guide bar.
9. The guide according to claim 1 , wherein the at least two guide bars are substantially mutually complementary, each guide bar having an L-shaped or a C-shaped cross-section, and aligned vertically.
10. The guide according to claim 1 , wherein the first bar carries a first magnet and the second bar carries a second magnet, the first and second magnets positioned as a pair of magnets facing each other, and the second bar carries at least one rolling element slidable on the first bar.
11. A sliding door or window, comprising:
a liftable sliding leaf and
a guide for liftable sliding leaf comprising:
at least two guide bars, a first bar of the at least two guide bars being able to be connected movably to a fixed support bar, the liftable sliding leaf being movable with respect to the fixed support bar, and a second bar of the at least two guide bars being able to be connected to a top part of the liftable sliding leaf and being movable integrally with said liftable sliding leaf;
both said first and second bars being liftable in a vertical plane from a first position, in which the liftable sliding leaf rests on the ground and movement thereof is locked, to a lifted position, in which the liftable sliding leaf is free to slide laterally,
wherein the second bar is a rigid member, elongated along the whole top edge of the liftable sliding leaf, and
wherein said liftable sliding leaf is slidable on said guide and is lockable in said first position.
12. The sliding door or window according to claim 11 , wherein the at least two guide bars and the liftable sliding leaf are mutually aligned in a vertical direction and do not laterally project out of an opening in a wall which is to be closed by the sliding door or window.
