Closure assembly

1 . A closure assembly comprising:

a pair of closure members with one designated as an active closure member and the other as a passive closure member; and

an astragal provided as a part connected to the passive closure member or as an integral extension of the passive closure member, wherein upon the passive closure member being reversed in orientation, the position of the astragal relative to the passive closure member remains unchanged to cover a gap between the closure members when the closure assembly is in a closed position;

wherein, a pair of sweep receivers each mounted on at least one of the closure members at both the top and bottom ends and each closure member having substantially the same thickness about its horizontal midline, such that each closure member can be configured as either a right or left closure member by adjusting its orientation.

2 . The closure assembly as claimed in claim 1 , wherein each sweep receiver comprises one or more complementary members configured to couple with a door sweep.

3 . The closure assembly as claimed in claim 2 , wherein the sweep receivers are configured to form a snap-fit connection with the door sweep.

4 . The closure assembly as claimed in claim 2 , wherein the sweep receivers are configured to form a snap-fit connection with the door sweep.

5 . The closure assembly as claimed in claim 1 , wherein at least one end of the astragal comprises a cover receiver, configured to couple with a cover.

6 . The closure assembly as claimed in claim 5 , wherein at least one of the closure members comprises a handle receiver configured to couple with a handle, enabling operation in different orientations.

7 . The closure assembly as claimed in claim 6 , wherein at least one of the closure members comprises one or more strike plate receivers configured to couple with one or more strike plates, enabling operation in different orientations.

8 . The closure assembly as claimed in claim 6 , wherein at least one of the handle receiver and a strike plate receiver is positioned substantially in the middle portion of respective closure members.

9 . The closure assembly as claimed in claim 7 , wherein at least one of the handle receiver and the strike plate receiver is positioned substantially in the middle portion of respective closure members.

10 . The closure assembly as claimed in claim 7 , wherein at least one of the closure members comprises a pair of wind stopper receivers at opposite ends.

11 . The closure assembly as claimed in claim 10 , wherein any one of the cover receiver, the handle receiver, the strike plate receiver and the wind stopper receiver comprises screw threads to ensure secure coupling.

12 . The closure assembly as claimed in claim 1 , further comprising a closure frame, to which the closure members are coupled.

13 . The closure assembly as claimed in claim 12 , wherein each closure member can be configured to be hinged on either the right or left side of the closure frame.

14 . A method for changing an opening orientation of a closure assembly as claimed in claim 13 , wherein the hinged side of each closure member relative to the closure frame is reversed, the method comprising the steps of:

unfastening each closure member from the closure frame;

vertically flipping each closure member, repositioning and fastening each closure member to an opposite side of the closure frame;

removing a top and a bottom wind stoppers from at least one of the closure members, and mounting the wind stoppers to respective opposite ends of the at least one closure member;

removing a strike plate from a strike plate receiver of the passive closure member and reassembling the strike plate to the strike plate receiver in a reversed orientation;

removing a cover from one end of the passive closure member and mounting the cover to the bottom of the passive closure member; and

removing a door sweep from one sweep receiver and mounting the door sweep to the sweep receiver at the bottom of the passive closure member.
