Improvements in screen doors
A screen assembly (100) comprising a mesh screen (110) mounted in a surrounding frame assembly which includes a frame member (10) defining a channel (12) having an end wall (18) and opposed side walls (14, 16), the opposed side walls defining first engaging formations (20, 22). The assembly further includes a generally U-shaped seat (30) defining a channel (40) and first (34) and second (32) side arms and sandwiching a marginal edge section of the screen therebetween and the external faces of the first and second side arms define second and third engaging formations (35, 33) respectively. The second engaging formations (33) of the seat engage the first engaging formations (33) of one of the opposed end walls. A wedge element (50) is provided for compressing the U-shaped seat (30) and is disposed between the generally U-shaped seat (30) and one end wall of the channel. The sides of the wedge element (50) define fourth engaging formations engaging with the first engaging formations of the frame member and the third engaging formations of the U-shaped seat and compress the generally U-shaped seat against one side wall of the channel, with the engaged formations inhibiting removal of the screen from the frame. ~vv#-v-i7R iG2 40 N+ NG IbZ 7cv-5 5 40 1 bO lb
