| 摘要 |
This door joint comprises a fixing element (1) covering a projecting part (2) of a door-frame (3) and two tubular elements (6 and 8) made of a material deformed in an elastic manner, whereby one tubular element (6) adjoins the other tubular element (8) and said fixing element (1), said tubular elements (6 and 8) are to be interposed between door-frame (3) and associated door (7) in its closed position in order to ensure the tightness of the assembly. According to the invention, the two tubular elements (6 and 8) communicate through at least one orifice (9) or through a continuous passage, whereby the compression of one of the tubular elements (6) between the door and the door-frame results in the deformation of said latter element and in an inflation of the second tubular element (8) between said door and said door-frame.
