Abstract
A joint device for drain pipes comprises a structural tube made of a rigid material and providing structural integrity to the joint device. The structural tube defines at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network. An annular seal of resilient sealing material is integrally connected to an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device.
Claims19
An assembly comprising:
- a pipe configured to be connected to a drain network;
- a joint device including a structural tube made of a rigid material and providing structural integrity to the joint device, the structural tube defining at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for direct complementary abutment sealing engagement with said pipe, and
- an annular seal of resilient sealing material integrally and inseparably connected to an inner diameter of an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions configured for sealing engagement with a tailpiece slid downwardly into engagement with the joint device, an inner diameter of the bottom portion of the structural tube being larger than an outer diameter of a portion of the tailpiece engaged with the joint device;
- and
- wherein an inner diameter of the pipe is larger than the outer diameter of the portion of the tailpiece, and
- wherein the pipe has a constant outer diameter all along the direct complementary abutment sealing engagement with said joint device.
An assembly comprising:
- a joint device including a structural tube made of a rigid material and providing structural integrity to the joint device, the structural tube defining at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network and an annular seal of resilient sealing material integrally and inseparably connected to an inner diameter of an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device, the bottom portion having a constant inner diameter all along the complementary sealing engagement with the pipe, and
- a tailpiece having an outer diameter sized for penetrating the drain passage and for sealing engagement with the annular seal when slid into engagement with the joint device, an inner diameter of the bottom portion of the structural tube being larger than the outer diameter of the tailpiece, the outer diameter of the tailpiece being smaller than an inner diameter of the pipe of the drain network.
