摘要
The lip-type seal for the bottom closure of the inlet opening (2) for dagger board housing (3) and dagger board (4), intended for sailboards, exhibits two mounting strips (6) of a hard plastic with a sealing lip (7) of an elastic plastic, countersunk on both sides of the inlet opening into the board hull (1) and terminating with the profile (5) of the underwater hull. The mounting strip (6) is fashioned as a U-profile with an inner (8) and an outer, short leg (9), these legs being joined by a web (10) extending obliquely in correspondence with the profile (5) of the underwater hull. The sealing lip (7) adjoining the mounting web (10) of the mounting strip (6) has a rounded sealing edge (11) passing over into an elastic supporting leg (12) oriented obliquely upwardly, the supporting leg being attached to the outer leg (9) of the mounting strip (6). The mounting strip (6) is pressed or glued, with the inner leg (8), into a corresponding groove (14) in the board hull (1). The sealing lip (7) forms, together with the supporting leg (12) and the outer leg (9) of the mounting strip (6), an elastic hollow-profile strip (18).
