摘要
A pivotal straight, elbow, T, Y or cross fitting for indoor sewer systems comprises a first portion(10), and a secondportion(20) that is pivotally attached to the first portion (10). One of said portions has a wall (11) defining a socket in the shape of an internally sphericalzone (14), and the other portionhas an end (21) in the shape of a mating 5 externallyspherical zone (24). According to the invention, the internallyspherical zone (14) is cup-shaped and diverges toward an opening facing the externally spherical zone (24) to permit entrythereof into surface contact between the two zones (14, 24). The externallyspherical zone (24) has two diametrically opposed stub shafts (25) arranged to forma hinge axis for the secondportion(20) in a hinge joint, and clamping means 10 (30) are provided for maintaining the two spherical zones (14, 24) clamped against each other.
