Packing strip structure

Claim 2

A packing strip structure adapted to be mounted on a flange comprising a. at least one mounting member having generally parallel side portions, the side portions bearing a plurality of oppositely positioned and inwardly projecting tongues, and wherein the width of the base portion of each tongue is greater than the combined width of the distances from each end of the base to the adjacent side of the member, whereby upon insertion of a flange which passes over and between said tongues, such passage causes the lower ends of the mounting member to move inwardly toward each other, and b. a resilient packing member having an opening adapted to receive said mounting member, the edges of said opening having integral lip portions which encase the ends of the mounting member and bear against a portion of the oppositely positioned inner surfaces thereof.

Claim 3

A packing strip structure adapted to be mounted on a flange comprising a. a generally U-shaped mounting member consisting of a plurality of adjacently positioned interconnected sections, each of such sections being shaped to form a U and having oppositely positioned and inwardly projecting tongues, the tips of the oppositely positioned tongues approaching each other; and wherein the width of the base portion of each tongue is greater than the combined width of the distances from each end of the base to the adjacent side of the section, whereby upon insertion of a flange, which passes over and between said tongues, such passage causes the lower ends of the mounting member to move inwardly toward each other, and b. a resilient packing member having an opening adapted to receive said mounting member, the opposing edges of said opening having integral overlapping lip portions which receive the oppositely positioned ends of said sections.

Claim 4

A packing strip structure adapted to be mounted on a flange comprising a. a generally U-shaped mounting member consisting of a plurality of adjacently positioned interconnected sections, each of such sections being shaped to form a U and having oppositely positioned and inwardly projecting tongues, the tips of the oppositely positioned tongues approaching each other; and wherein the width of the base portion of each tongue is greater than the combined width of the distances from each end of the base to the adjacent side of the section, whereby upon insertion of a flange, which passes over and between said tongues, such passage causes the lower ends of the mounting member to move inwardly toward each other, and b. a resilient packing member having an opening adapted to receive said mounting member, the opposing edges of said opening having integral overlapping lip portions which receive the oppositely positioned ends of said sections.

Claim 5

The packing strip structure of claim 2 wherein said packing member is a foam material.

Claim 6

The packing strip structure of claim 2 wherein the tips of the oppositely positioned tongues are in contiguous relationship.

Claim 7

The packing strip structure of claim 2 wherein two adjacent sections are connected by two spaced apart connecting bands to form a doubly connected pair of sections which, in turn, is joined by a single centrally positioned connecting band to an adjacent doubly connected pair.

Claim 8

The packing strip structure of claim 2 wherein each section is connected by a single connecting band to an adjacent section, every other connecting band being centrally positioned along the length of said mounting member.

Claim 9

The packing strip structure of claim 6 wherein the non-centrally positioned bands are positioned on the same side of the centrally positioned bands in a straight line along the length of said mounting member.

Claim 10

The packing strip structure of claim 6 wherein the non-centrally positioned bands are alternately positioned on opposite sides of said centrally positioned bands.

Claim 11

The packing strip structure of claim 2 wherein each section, prior to shaping, is rectangular and has two inwardly directed angular tongues positioned on opposite sides thereof.

Claim 12

In combination with a flange for a support, a packing strip structure comprising a. a U-shaped mounting member having a plurality of interconnected sections, the sides of said sections being aligned to form oppositely positioned parallel sides of said member, said sides bearing a plurality of oppositely positioned inwardly projecting tongues, the tips of which extend toward each other, and wherein the width of the base portion of each tongue is greater than the combined width of the distances from each end of the base to the adjacent side of the member, whereby upon insertion of a flange which passes over and between said tongues, such passage causes the lower ends of the mounting member to move inwardly toward each other, and b. a resilient packing member having an opening to receive said mounting member, the opposing edges of said opening having integral overlapping lip portions which receive the oppositely positioned ends of said sections; the flange on which the packing strip structure is mounted being resiliently held by said tongues and causing separation of the tips of said tongues and movement of the lower side ends of the mounting member toward each other to an extent corresponding to the extent of separation of said tips, thereby increasing the clamping retention of the packing strip structure to the flange.

Claim 13

In combination with a flange for a support, a packing strip structure comprising a. a U-shaped mounting member having a plurality of interconnected sections, the sides of said sections being aligned to form oppositely positioned parallel sides of said member, said sides bearing a plurality of oppositely positioned inwardly projecting tongues, the tips of which extend toward each other, and wherein the width of the base portion of each tongue is greater than the combined width of the distances from each end of the base to the adjacent side of the member, whereby upon insertion of a flange which passes over and between said tongues, such passage causes the lower ends of the mounting member to move inwardly toward each other, and b. a resilient packing member having an opening to receive said mounting member, the opposing edges of said opening having integral overlapping lip portions which receive the oppositely positioned ends of said sections; the flange on which the packing strip structure is mounted being resiliently held by said tongues and causing separation of the tips of said tongues and movement of the lower side ends of the mounting member toward each other to an extent corresponding to the extent of separation of said tips, thereby increasing the clamping retention of the packing strip structure to the flange.
