Abstract
Abstract A bulb-type sealing gasket formed from linear sealing strips and curvelinear sealing corners connected to one another. The sealing strip is constructed from a planar strip of flexible resilient material having end portions which extends substantially perpendicularly to the plane of the sealing strip. The upper sections of the end portions are configured into mounting flanges and the lower sections are configured into cooperating male and female locking elements so that, when the strip is rolled about its longitudinal axis and the cooperating locking elements are snapped together, a bulb-type sealing strip is formed which has a pair of oppositely extending co-planar flanges for mounting upon a closing member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
A bulb-type, linear sealing strip for securing to the surface of a member adapted to close an opening in a wall structure, said sealing strip: being formed from a generally planar strip of elastomeric, resilient material having opposite end portions which extend substantially at right angles to said planar strip, said end portions each having an upper section extending above said planar strip and a lower section extending below said planar strip; the lower sections being shaped to form cooperating male and female locking elements which, upon being snapped together when the strip is rolled about its longitudinal axis, deform said planar strip into a bulb-type shape; and the upper sections being substantially identical to one another and being shaped to form a pair of flanges for mounting said gasket to the surface of the member, said mounting flanges extending into opposite directions for mounting to the member when said locking elements are snapped together.
Claim 2
Dependent Claim
155 words
A bulb-type, linear sealing strip for securing to the surface of a member adapted to close an opening in a wall structure, said sealing strip: being formed from a generally planar strip of elastomeric, resilient material having opposite end portions which extend substantially at right angles to said planar strip, said end portions each having an upper section extending above said planar strip and a lower section extending below said planar strip; the lower sections being shaped to form cooperating male and female locking elements which, upon being snapped together when the strip is rolled about its longitudinal axis, deform said planar strip into a bulb-type shape; and the upper sections being substantially identical to one another and being shaped to form a pair of flanges for mounting said gasket to the surface of the member, said mounting flanges extending into opposite directions for mounting to the member when said locking elements are snapped together.
Claim 3
Dependent Claim
29 words
A bulb-type linear sealing strip in accordance with claim 1 in which the lower surfaces of said flanges of the snapped-together gasket are co-planar for securing to the member.
Claim 4
Dependent Claim
33 words
A bulb-type linear sealing strip in accordance with claim 2 in which the surface of the snapped-together gasket, which is to be secured to the member, is planar under the cooperating locking elements.
Claim 5
Dependent Claim
20 words
A bulb-type linear sealing strip in accordance with claim 1 in which said locking elements are trapezoidal in cross section.
Claim 6
Dependent Claim
20 words
A bulb-type linear sealing strip in accordance with claim 1 in which said locking lements are bulb-shaped in cross section.
Claim 7
Dependent Claim
20 words
A bulb-type linear sealing strip in accordance with claim 1 in which said locking elements are arrowhead in cross section.
Claim 8
Dependent Claim
21 words
A bulb-type linear sealing strip in accordance with claim 1 in which said locking elements Christmas tree shaped in cross section.
Claim 9
Dependent Claim
144 words
A bulb-type sealing gasket comprising: a plurality of bulb-type linear sealing strips, said sealing being formed from a generally planar strip of elastomeric, resilient material having opposite end portions which extend substantially at right angles to said planar strip, said end portions each having an upper section extending above said planar strip and a lower section extending below said planar strip, the lower sections being shaped to form cooperating male and female locking elements which, upon being snapped together when the strip is rolled about its longitudinal axis, deform said planar strip into a bulb-type shape, and both upper sections being substantially identical to one another and being shaped to form a pair of flanges for mounting said gasket to the surface of the member, said mounting flanges extending into opposite directions for mounting to the member when said locking elements are snapped together.
Claim 10
Dependent Claim
144 words
A bulb-type sealing gasket comprising: a plurality of bulb-type linear sealing strips, said sealing being formed from a generally planar strip of elastomeric, resilient material having opposite end portions which extend substantially at right angles to said planar strip, said end portions each having an upper section extending above said planar strip and a lower section extending below said planar strip, the lower sections being shaped to form cooperating male and female locking elements which, upon being snapped together when the strip is rolled about its longitudinal axis, deform said planar strip into a bulb-type shape, and both upper sections being substantially identical to one another and being shaped to form a pair of flanges for mounting said gasket to the surface of the member, said mounting flanges extending into opposite directions for mounting to the member when said locking elements are snapped together.
Claim 11
Dependent Claim
17 words
A bulb-type sealing gasket in accordance with claim 8 in which the gasket comprises a closed loop.
Claim 12
Dependent Claim
37 words
A bulb-type sealing gasket in accordance with claim 8 in which said gasket comprises four linear sealing strips and four corners, and in which the corners include means for sealingly receiving the end portion of said strips.
