Abstract
A window or a door comprises a stationary frame and two leaf frames. The leaf frames are mounted for pivoting movement about mutually parallel pivot axes. A first leaf frame is intended for more frequent opening and closing, and a second leaf frame is intended for less opening and closing. The second leaf frame can be locked with respect to the stationary frame by drive rods which move in opposite sense and which engage the stationary frame at the respective ends thereof. The first leaf frame is provided with the vertical height of the first leaf frame. This first drive rod is driven by a first drive mechanism. The first drive rod controls transverse bolts for engagement with the second leaf frame. The transverse bolts driven by the first drive rod are located outside the first drive mechanism.

A locking system for use on a window or a door, this window (10) or this door, respectively, comprising a stationary frame (12) and two leaf frames (14, 16) mounted on this frame (12) so that they pivot about mutually parallel pivot axes (S1, S2), a first leaf frame (14) of these two leaf frames (14, 16) being intended for frequent pivoting movement about a first pivot axis (S1) between an open position and a closed position, a second leaf frame (16) being intended for less frequent pivoting movement about a second pivot axis (S2) between a closed position and an open position, each of the two leaf frames (14, 16) comprising a leaf frame member (14a, 16a) remote from the respective pivot axis (S1, S2), the first leaf frame (14) having a first leaf frame member (14a) and the second leaf frame (16) having a second leaf frame member (16a), said first leaf frame member (14a) and said second leaf frame member (16a) being in the closed position of the respective leaf frames (14, 16) directly opposite each other, i.e. without the interposition of an intermediate member which is rigid with the stationary frame (12), said second frame (16) being, in the region of the second leaf frame member (16a), lockable by second locking means (22a, 22a) with respect to transverse members (12a, 12b) of the stationary frame (12) which extend substantially at right-angles to the first and second leaf frame members (14a, 16a), said first leaf frame (14) being lockable in the region of the first leaf frame member (14a) by first locking means (28, 32, 36, 38) with respect to the second leaf frame member (16a), said second locking means comprising, for being mounted on the second leaf frame member (16a) between the two transverse members (12a, 12b) a second drive unit (18), a second drive rod assembly (46, 48) for being mounted on and parallel with the second leaf frame member (16a) and having two second drive rod elements (22, 24) adapted for movement in opposition to each other and parallel with the second leaf frame member (16a) as a result of actuation of the second drive unit (18), a respective second drive rod end lock element (22a, 24a) being provided at respective ends of both said second drive rod elements (22, 24) for engagement in respective second drive rod end lock element receiver means (12c, 12d) allocated to respective transverse members (12a, 12b), said locking system further comprising a first drive unit (26) for being mounted on the first leaf frame member (14a) between said two transverse members (12a, 12b), said first drive unit (26) being adapted for controlling transverse latch means (28) having at least one transverse latch (28) having at least one transverse latch (28) crossing a leaf frame middle gap and engageable with latch receiving means (30) to be provided on the second leaf frame member (16a), said first drive unit (26) being further adapted to control transverse bolt means (32, 36, 38) which cross the leaf frame middle gap and are engageable with respective transverse bolt receiving means (33, 40, 42) to be provided on the second leaf frame member (16a), a first drive rod assembly (34) being provided for being fastened to said first leaf frame member, (14a), said first drive rod assembly (34) extending over a major part of the length of the first leaf frame member 914a) and being adapted for movement by the first drive unit (26) in a longitudinal direction of the first leaf frame member (14a), said transverse bolt means (32, 36, 38) comprising a plurality of transverse bolts (32, 36, 38), at least a part (36, 38) of said transverse bolts of said plurality of transverse bolts (32, 36, 38) being controlled via said first drive rod assembly (34) and being situated outside said first drive unit (26).
A locking system for use on a window or a door, this window (10) or this door, respectively, comprising a stationary frame (12) and two leaf frames (14, 16) mounted on this frame (12) so that they pivot about mutually parallel pivot axes (S1, S2), a first leaf frame (14) of these two leaf frames (14, 16) being intended for frequent pivoting movement about a first pivot axis (S1) between an open position and a closed position, a second leaf frame (16) being intended for less frequent pivoting movement about a second pivot axis (S2) between a closed position and an open position, each of the two leaf frames (14, 16) comprising a leaf frame member (14a, 16a) remote from the respective pivot axis (S1, S2), the first leaf frame (14) having a first leaf frame member (14a) and the second leaf frame (16) having a second leaf frame member (16a), said first leaf frame member (14a) and said second leaf frame member (16a) being in the closed position of the respective leaf frames (14, 16) directly opposite each other, i.e. without the interposition of an intermediate member which is rigid with the stationary frame (12), said second leaf frame (16) being, in the region of the second leaf frame member (16a), lockable by second locking means (22a, 24a) with respect to transverse members (12a, 12b) of the stationary frame (12) which extend substantially at right-angles to the first and second leaf frame members (14a, 16a) said first leaf frame (14) being lockable in the region of the first leaf frame member (14a) by first locking means (28, 32, 36, 38) with respect to the second leaf frame member (16a), said second locking means comprising, for being mounted on the second leaf frame member (16a) between the two transverse members (12a, 12b), a second drive unit (18) for controlling said second locking means (22a, 24a), said first locking means comprising a first drive unit (26) for being mounted on said first leaf frame member (14a) between said two transverse members (12a, 12b), said first drive unit (26) being adapted for controlling at least one lock member (28, 32, 36, 38) of said first locking means movably mounted on said first leaf frame member (14a) for crossing a leaf frame middle gap and being engaged with lock member receiving means (30, 33, 40, 42) to be provided on the second leaf frame member (16a), said lock member receiving means (30, 33, 40, 42) being controllable by said second drive unit (18) to enter into a condition of inability to receive said at least one lock member (28, 32, 36, 38) in a release position of said second drive unit (18) in which said second leaf frame (16) is unlocked with respect to said transverse members (12a, 12b).
