However, since small gap still exists between the door panel (61) and the wind shielding block (27), the motion of the sliding door panel (61) shall not be affected by the assembly.
Moreover, when the sliding door panel (61) is in closed condition, the upper wind shielding block (27) can seal up the gap formed on the upper end of the sliding door panel (61) and the upper end of the stationary door panel (62).
As shown in Figure 2 to 5 and Figure 14 to 16, a rain shielding strip (80) is provided along the edge of the inner side of the stationary door panel (62) comprising a L-shaped strip (81) and a soft packing strip (82). The lower end of the rain shielding strip (80) is arranged to touch the top surface (97) of the lower wind shielding block (95), and, when the sliding door panel (61) is in closed condition, the upper end of the rain shielding strip (80) almost touches the upper wind shielding block (27).
Therefore, when the sliding door panel (61) is in closed condition the gap between the sliding door panel (61) and the stationary door panel (62) can be completely sealed up by the upper wind shielding block (27), the lower wind shielding block (95) and the rain shielding strip (80). Particularly, not only the tight contact formed between the soft packing strip (82) of the rain shielding strip (80) and the sliding door panel (61) provides the effect of preventing the water from seeping into the room, but also the L-shaped strip (81) of the rain shielding strip (80) of the stationary door panel (62) and another L-shaped strip (86) of the rain shielding strip (85) of the sliding door panel (61) are arranged to extend across each other to form a structure that can effectively prevent the water from seeping into the room.
Also, on the inner side of the sliding door panel (61) a soft packing strip (87) is provided on the rain shielding strip (85) which has its upper end touching the upper wind shielding block (27), and, when the sliding door panel (61) is in closed condition, the lower end of the rain shielding strip (80) almost touches the top surface (97) of the lower wind shielding block (95), therefore, when the sliding door panel (61) is in closed condition the gap between the sliding door panel (61) and the stationary door panel (62) is completely sealed up by the upper wind shielding block (27), lower wind shielding block (95) and the rain shielding strip (85). Further, since the soft packing strip (87) on the rain shielding strip (85) forms tight contact with the stationary door panel (62), it also provides the effect of preventing the water from seeping into the room.
Besides, on the L-shaped strip (81) a soft gastight strip (88) is further provided to increase the gastight-effect of the rain shielding strip (80) and rain shielding strip (85) which are arranged to across each other.
