A latch mechanism (16a, 16b; 50; 60) for latching a door or window panel (14; 61; 65a, 65b) to a frame (12; 62), said door or window panel (14; 61; 65a, 65b) comprising a front surface, a back surface and one or more edge surfaces extending between the front and back surfaces, the latch mechanism (16a, 16b; 50; 60) including: a pair of first members, a first of the pair of first members being located in an upper region of either the door or window panel (14; 61; 65a, 65b) or the frame (12; 62), and a second of the pair of first members being located in a lower region of either the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) and a pair of second members, a first of the pair of second members being located in an upper region of the other of the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) to the first of the pair of first members and a second of the pair of second members being located in a lower region of the other of the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) to the second of the pair of first members, the second members being movable between an unlatched position and a latched position wherein the second members are brought into abutment with, or close proximity to, the respective first members, a controller comprising a handle, said handle being locatable within a recess in the edge surface of the door or window panel (14; 61; 65a, 65b), wherein the second members are adapted to move from the unlatched position to the latched position under a magnetic attraction to the respective first members when the door or window panel (14; 61; 65a, 65b) is brought into a closed condition, and wherein the second members are coupled to the controller via one or more linkage members, said one or more linkage members comprising one or more cables (24a, 24b), wherein actuation of the controller results in moving the second members from the latched position to the unlatched position, and wherein slack is allowed to exist in the one or more linkage members when the second members are in the unlatched position such that, as the first and second members are brought into proximity with one another, the slack in the linkage members is sufficient to allow movement under magnetic attraction of the second members towards the first members into the latched position. a pair of first members, a first of the pair of first members being located in an upper region of either the door or window panel (14; 61; 65a, 65b) or the frame (12; 62), and a second of the pair of first members being located in a lower region of either the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) and a pair of second members, a first of the pair of second members being located in an upper region of the other of the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) to the first of the pair of first members and a second of the pair of second members being located in a lower region of the other of the door or window panel (14; 61; 65a, 65b) or the frame (12; 62) to the second of the pair of first members, the second members being movable between an unlatched position and a latched position wherein the second members are brought into abutment with, or close proximity to, the respective first members, a controller comprising a handle, said handle being locatable within a recess in the edge surface of the door or window panel (14; 61; 65a, 65b), wherein the second members are adapted to move from the unlatched position to the latched position under a magnetic attraction to the respective first members when the door or window panel (14; 61; 65a, 65b) is brought into a closed condition, and wherein the second members are coupled to the controller via one or more linkage members, said one or more linkage members comprising one or more cables (24a, 24b), wherein actuation of the controller results in moving the second members from the latched position to the unlatched position, and wherein slack is allowed to exist in the one or more linkage members when the second members are in the unlatched position such that, as the first and second members are brought into proximity with one another, the slack in the linkage members is sufficient to allow movement under magnetic attraction of the second members towards the first members into the latched position.
