Abstract
The invention relates to a sealing cover 1, 1′ made of plastic, especially for sealing an opening in a support 50; 51; 52, with a base body 10; 10′, which merges into a circumferential collar 20, which transitions into an elastic sealing lip positioning itself against one side of a support, with the collar (20) presenting, at its outer circumference, an engaging ring 25; 25′, and with the sealing cover 1; 1′ designed in one single piece consisting of a thermoplastic elastomer and between the engaging ring 25; 25′ and the sealing lip 30; 30′ at least one second engaging ring 28 being arranged at the outer circumference of the collar 20.
Claims29
A sealing cover formed of a thermoplastic elastomer and adapted for sealing an opening in an associated support, the sealing cover comprising:
- a base body which merges with a circumferential collar which transitions into an elastic sealing lip abutting against one side of an associated support, whereby the collar presents, at its outer circumference an engaging ring and between the engaging ring and the sealing lip at the outer circumference of the collar is arranged at least one second engaging ring and further wherein the outer circumference of the collar defines a circumferential groove adjacent said second engaging ring, wherein between the second engaging ring and the sealing lip there is arranged a third engaging ring at the outer circumference of the collar, and wherein the third engaging ring is oriented towards the second engaging ring.
A sealing cover formed of a thermoplastic elastomer and adapted for sealing an opening in an associated support, the sealing cover comprising:
- a base body which merges with a circumferential collar which transitions into an elastic sealing lip abutting against one side of an associated support, whereby the collar presents, at its outer circumference an engaging ring and between the engaging ring and the sealing lip at the outer circumference of the collar is arranged at least one second engaging ring and further wherein the outer circumference of the collar defines a circumferential groove adjacent said second engaging ring, wherein between the second engaging ring and the sealing lip there is arranged a third engaging ring at the outer circumference of the collar, and wherein the third engaging ring is positioned in the groove which is formed by the outer circumference of the collar, and the elastic sealing lip is oriented towards the first engaging ring.
A sealing cover formed of a thermoplastic elastomer and adapted for sealing an opening in an associated support, the sealing cover comprising:
- a base body which merges with a circumferential collar which transitions into an elastic sealing lip abutting against one side of an associated support, whereby the collar presents, at its outer circumference an engaging ring and between the engaging ring and the sealing lip at the outer circumference of the collar is arranged at least one second engaging ring and further wherein the outer circumference of the collar defines a circumferential groove adjacent said second engaging ring, wherein the base body presents several ribs in the region of the sealing lip, and wherein the ribs are positioned diagonally opposite each other and have the shape of a wedge.
A sealing cover formed of a thermoplastic elastomer and adapted for sealing an opening in an associated support, the sealing cover comprising:
- a base body which merges with a circumferential collar which transitions into an elastic sealing lip abutting against one side of an associated support and which presents lattice-like extending ribs in the region of the sealing lip whereby the collar presents, at its outer circumference an engaging ring and between the engaging ring and the sealing lip at the outer circumference of the collar is arranged at least one second engaging ring and further wherein the outer circumference of the collar defines a circumferential groove adjacent said second engaging ring.
A sealing cover for insertion into an opening in an associated support for closing and sealing said opening, the sealing cover comprising:
- a base body having a base body portion and a circumferential collar sized and adapted for insertion into the opening in the associated support, the circumferential collar defining a circumferential groove;
- a peripheral elastic sealing lip formed integrally with said base body and extending radially outwardly of said circumferential collar to engage said associated support about said opening;
- a first peripheral engaging ring extending radially outwardly of said circumferential collar at a location axially spaced from the sealing lip and adapted to engage said panel circumferential about said opening on the side of said associated support opposite said sealing lip;
- and,
- at least one second peripheral engaging ring extending radially outwardly of said circumferential collar at a location between said peripheral elastic sealing lip and said first peripheral engaging ring, the at least one second peripheral engaging ring being selectively positioned in said circumferential groove when the sealing cover is received in said opening of said associated support, wherein the at least one second peripheral engaging ring includes a plurality of second peripheral engaging rings extending radially outwardly of said circumferential collar at locations between said peripheral elastic sealing lip and said first peripheral engaging ring, and wherein:
- at least a first ring of said plurality of second peripheral engaging rings extends radially outwardly of said circumferential collar at a first angle whereby the first ring is oriented towards an underside of said sealing lip;
- and,
- at least a second ring of said plurality of second peripheral engaging rings extends radially outwardly of said circumferential collar at a second angle whereby the second ring is oriented towards said first peripheral engaging ring.
A sealing cover for insertion into an opening in an associated support for closing and sealing said opening, the sealing cover comprising:
- a base body having a base body portion and a circumferential collar sized and adapted for insertion into the opening in the associated support, the circumferential collar defining a circumferential groove;
- a peripheral elastic sealing lip defining a groove and being formed integrally with said base body and extending radially outwardly of said circumferential collar to engage said associated support about said opening;
- a first peripheral engaging ring extending radially outwardly of said circumferential collar at a location axially spaced from the sealing lip and adapted to engage said panel circumferential about said opening on the side of said associated support opposite said sealing lip;
- and,
- at least one second peripheral engaging ring extending radially outwardly of said circumferential collar at a location between said peripheral elastic sealing lip and said first peripheral engaging ring, wherein the at least one second peripheral engaging ring includes a plurality of second peripheral engaging rings extending radially outwardly of said circumferential collar at locations between said peripheral elastic sealing lip and said first peripheral engaging ring, and at least one of said plurality of second peripheral engaging rings are selectively movable into said groove when the sealing cover is received in said opening of said associated support.
A sealing cover adapted for sealing an opening in an associated support, the sealing cover comprising:
- a base body which merges with a circumferential collar which transitions into an elastic sealing lip abutting against one side of the associated support;
- an engaging ring carried on an outer circumference of said collar;
- at least one second engaging ring carried on the outer circumference of said collar and disposed between the engaging ring and the sealing lip;
- and,
- a third engaging ring on the outer circumference of the collar between the second engaging ring and the sealing lip, wherein the third engaging ring is oriented towards the second engaging ring.
