[0007] The present invention has invented two preferred embodiments of doorsill structure for in-swinging type door particularly under stress of weather having the effect of shielding the winds and keeping off the water to prevent the water from seeping into the room.

[0008] The first embodiment of doorsill (10) of the invention is depicted as in Figure 1 through 4 which comprises a doorsill base (20) and a rain shielding plate (30), and those two components of doorsill base (20) and rain shielding plate (30) are assembled by using snap-in connecting means to form a complete assembly without using any fastening part.

[0009] In the invention the doorsill base (20) is formed by thermoplastic foam material or thermoplastic material by extruding forming techniques to form an integral structure which has a main-body seat (21) of greater height and a front-plate (22) connected to and extended from the front lower side of the main-body seat (21). Besides, a tenon-slot (26) for tenon connection purpose is formed at the junction position of the main-body seat (21) and the front-plate (22) of the doorsill base (20).

[0010] Further, on the top surface of the main-body seat (21) has a canal-shaped drainage canal (25) with proper depth formed along the longitudinal direction of the top surface of the main-body seat (21).

[0011] And, a protruding rib (23) having the effect similar to a dam-wall is formed on the top surface of the main-body seat (21) with proper height, and positioned with one side serving as the bank of the drainage canal (25) while the other side adjoining the front-plate (22). On the top side of the protruding rib (23) is an inclined rib (24) sloping down to the front-plate (22).

[0012] The purpose of forming the protruding rib (23) and the drainage canal (25) on the top surface of the main-body seat (21) is depicted as in Figure 4 which shows that when the hinged door (40) is closed, the bottom edge of the hinged door (40) is lower than the top edge of the protruding rib (23) of the main-body seat (21), therefore, as for the interior of the room (50), the protruding rib (23) functioned as a protecting wall for keeping off the winds and rainwater that shall effectively prevent the water from seeping into the room (50), meanwhile, the soft packing (45) installed on the hinged door (40) and positioned between the hinged door (40) and the protruding rib (23) are pressed by each other to form a tight contact, and on the top surface of the protruding rib (23) is a inclined rib (24) arranged to incline down to the front plate (22) which has the effect of draining off the rainwater rapidly and the effect of minimizing the seepage of water into the room (50).

[0013] Accordingly, if by any chance there is a gap existed between the contacting surface of the protruding rib (23) and the soft packing (45) through which water seep into the room (50), the water will flow into the drainage canal (25), and will be guided and drained away from the drainage canal (25), especially, another soft packing (46) is tightly pressed against the edge of the bank on another side of the drainage canal (25) which provides further effect of preventing the water from seeping into the room (50).
