Zip strip seal
The invention provides a seal assembly operable to form a seal between two housing parts. The seal assembly includes a deformable sealing member extending along a first enclosed path. The sealing member defines a channel cross-section perpendicular to the first enclosed path. The seal assembly also includes a strip member extending along a second enclosed path substantially similarly shaped as the first enclosed path. The strip member defines a strip cross-section perpendicular to the second enclosed path. The strip cross-section is substantially similarly shaped as the channel cross-section of the sealing member. The strip member is releasibly inserted in the channel cross-section to seal and substantially fix the two housing parts relative to one another.
1 . A seal assembly operable to form a seal between two housing parts comprising:
a deformable sealing member extending along a first enclosed path and defining a channel cross-section perpendicular to said first enclosed path; and
a strip member extending along a second enclosed path substantially similarly shaped as said first enclosed path and defining a strip cross-section perpendicular to said second enclosed path and substantially similarly shaped as said channel cross-section of said sealing member wherein said strip member is releasibly inserted in said channel cross-section to seal and substantially fix the two housing parts relative to one another.
2 . The seal assembly of claim 1 wherein said sealing member is operable to be positioned between the two housing parts before said strip member is releasibly inserted in said channel cross-section.
3 . The seal assembly of claim 1 wherein said channel cross-section is at least partially v-shaped and said strip cross-section is wedge-shaped.
4 . The seal assembly of claim 1 wherein said channel cross-section is arrow-shaped with a first head portion and a first shaft portion and said strip cross-section is arrow-shaped with a second head portion received in said first head portion and a second shaft portion received in said first shaft portion.
5 . The seal assembly of claim 1 further comprising:
first and second grooves individually defined by the two housing parts and facing one another spaced a distance apart wherein said sealing member being deformably compressed between said strip member and said first groove and being deformably compressed between said strip member and said second groove and wherein said strip member is spaced from said first and second grooves.
6 . The seal assembly of claim 5 wherein said first and second grooves are substantially mirrored with respect to one another about said strip member.
7 . The seal assembly of claim 6 wherein said first and second grooves cooperate to define a hastate cross-section.
8 . The seal assembly of claim 7 wherein a body cross-section of said sealing member perpendicular to said first enclosed path is hastate and sized to be received in said hastate cross-section defined by said first and second grooves
9 . The seal assembly of claim 8 wherein said channel cross-section is arrow-shaped with a first head portion and a first shaft portion and said strip cross-section is arrow-shaped with a second head portion received in said first head portion and a second shaft portion received in said first shaft portion.
10 . A method to form a seal between two housing parts comprising:
defining a channel cross-section with a deformable sealing member extending along a first enclosed path and wherein the channel cross-section is perpendicular to the first enclosed path; and
extending a strip member along a second enclosed path substantially similarly shaped as the first enclosed path and defining a strip cross-section perpendicular to the second enclosed path and substantially similarly shaped as the channel cross-section of the sealing member; and
releasibly inserting the strip member in the channel cross-section to seal and substantially fix the two housing parts relative to one another.
11 . The method of claim 11 further comprising the step of:
aligning first and second grooves individually defined by the two housing parts to face one another a spaced distance apart prior to said releasibly inserting step.
12 . The method of claim 11 further comprising the step of:
releasibly inserting the deformable sealing member between the first and second grooves prior to said step of releasibly inserting step the strip member.
13 . The method of claim 12 wherein said step of releasibly inserting the deformable sealing member is subsequent to said aligning step.
14 . The method of claim 13 wherein said step of releasibly inserting the strip member is further defined as:
compressing the sealing member perpendicular to the first enclosed path between the strip member and the first groove and as well as between the strip member and the second groove.
