Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
190 words
A sealing device for sealing the gap between the marginal portions defining an opening in a building and an object in said opening, which includes holding means defining an opening and being adapted to be connected to the marginal area of wall means defining a similarly sized opening, and a plurality of closely adjacent flexible elastic strip means supported on edge by said holding means and extending horizontally into the area of said opening thereof, said holding means including frame means for connection to a wall and also including holding members slidably arranged in said frame means, said holding members including means for receiving and clamping therein one end of said strip means, said frame means comprising rail means receiving said holding members, and said rail means defining a single groove having a width equalling approximately twice the width of one of said holding members, said holding members being arranged in said rail means in two adjacent rows, said strip means of one row being held by said holding memberS at an acute angle with regard to the strip means held in the adjacent row by the pertaining holding members.
Claim 2
Dependent Claim
190 words
A sealing device for sealing the gap between the marginal portions defining an opening in a building and an object in said opening, which includes holding means defining an opening and being adapted to be connected to the marginal area of wall means defining a similarly sized opening, and a plurality of closely adjacent flexible elastic strip means supported on edge by said holding means and extending horizontally into the area of said opening thereof, said holding means including frame means for connection to a wall and also including holding members slidably arranged in said frame means, said holding members including means for receiving and clamping therein one end of said strip means, said frame means comprising rail means receiving said holding members, and said rail means defining a single groove having a width equalling approximately twice the width of one of said holding members, said holding members being arranged in said rail means in two adjacent rows, said strip means of one row being held by said holding memberS at an acute angle with regard to the strip means held in the adjacent row by the pertaining holding members.
Claim 3
Dependent Claim
33 words
