Wall feedthrough
View Patent ↗The invention relates to a wall feedthrough having a frame which is divided by at least one intermediate web into at least two chambers, wherein at least one grommet of elastic material is arranged in each of the chambers, and wherein the grommet has at least one passage opening for accommodating an elongated object to be passed through the wall. It is provided according to the invention that two adjacent grommets, having an intermediate web between them, are respectively designed in such a way that they overlap the intermediate web on at least one side of the frame in the longitudinal direction of the elongated objects over the entire height of one side edge of the grommet and make sealing contact with each other.
1. Wall feedthrough having a frame which is divided by at least one intermediate web into at least two chambers, wherein at least one grommet of elastic material of a plurality of grommets of elastic material is arranged in each of the chambers, and wherein each grommet of the plurality of grommets has at least one passage opening for accommodating an elongated object to be guided through a wall,
wherein two adjacent grommets of the plurality of grommets, having an intermediate web between them, are respectively sized and shaped in such a way that they overlap the intermediate web between them on at least one side of the frame in the longitudinal direction of the elongated objects over the height of one side edge of the two adjacent grommets and make a sealing contact with each other.
2. Wall feedthrough according to claim 1 , wherein the two adjacent grommets have corresponding profiles in an area of the sealing contact overlapping the intermediate web.
3. Wall feedthrough according to claim 2 , wherein the corresponding profiles are designed as opposing bevels, steps and/or tongue and groove connection.
4. Wall feedthrough according to claim 2 , wherein the corresponding profiles form a labyrinth seal.
5. Wall feedthrough according to claim 1 , wherein the areas of the two adjacent grommets overlapping the intermediate web lie flat against the intermediate web.
6. Wall feedthrough according to claim 1 , wherein each of the plurality of grommets overlap the frame on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
7. Wall feedthrough according to claim 1 , wherein the frame overlaps each of the plurality of grommets on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
8. Wall feedthrough according to claim 1 , wherein each of the plurality of grommets interact in a form-fitting manner with the intermediate webs and/or the frame.
9. Wall feedthrough according to claim 1 , wherein each of the plurality of grommets are made of elastic material with a hardness of 30 to 70 Shore A.
10. Wall feedthrough according to claim 1 wherein the frame is made of a material with a hardness of at least 80 Shore A.
11. Wall feedthrough according to claim 1 , wherein each passage opening in each of the plurality of grommets is provided with a slot for unfolding the grommet.
12. Wall feedthrough according to claim 3 , wherein the corresponding profiles form a labyrinth seal.
13. Wall feedthrough according to claim 2 , wherein the areas of the two adjacent grommets overlapping the intermediate web lie flat against the intermediate web.
14. Wall feedthrough according to claim 3 , wherein the areas of the two adjacent grommets overlapping the intermediate web lie flat against the intermediate web.
15. Wall feedthrough according to claim 4 , wherein the areas of the two adjacent grommets overlapping the intermediate web lie flat against the intermediate web.
16. Wall feedthrough according to claim 2 , wherein each of the plurality of grommets overlap the frame on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
17. Wall feedthrough according to claim 3 , wherein each of the plurality of grommets overlap the frame on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
18. Wall feedthrough according to claim 4 , wherein each of the plurality of grommets overlap the frame on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
19. Wall feedthrough according to claim 5 , wherein each of the plurality of grommets overlap the frame on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
20. Wall feedthrough according to claim 2 , wherein the frame overlaps each of the plurality of grommets on at least one side of the frame in the longitudinal direction of the elongated objects by a certain distance.
