Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A sealing arrangement for sealing two tubular members of a floor care device, the tubular members being axially movable toward and away from one another and arranged to pass a gaseous medium, the sealing arrangement comprising an elastic ring arranged to be provided on one of said tubular members and having two lips, said lips including radially inner and outer lips located V-shaped and having an end face; and a V-shaped edge arranged to be provided on an end face of the other of said tubular members and cooperating with said radially outer lip of said elastic ring upon movement of the tubular members toward one another.
Claim 2
Dependent Claim
107 words
A sealing arrangement for sealing two tubular members of a floor care device, the tubular members being axially movable toward and away from one another and arranged to pass a gaseous medium, the sealing arrangement comprising an elastic ring arranged to be provided on one of said tubular members and having two lips, said lips including radially inner and outer lips located V-shaped and having an end face; and a V-shaped edge arranged to be provided on an end face of the other of said tubular members and cooperating with said radially outer lip of said elastic ring upon movement of the tubular members toward one another.
Claim 3
Dependent Claim
33 words
An arrangement as defined in claim 1, wherein said elastic ring has a predetermined diameter, said radially outer lip extending radially outwardly beyond a circumference corresponding to the diameter of said elastic ring.
Claim 4
Dependent Claim
39 words

Claim 7
Dependent Claim
21 words
An arrangement as defined in claim 5, wherein said radially inner lip of said elastic ring extends in an axial direction.
Claim 8
Dependent Claim
48 words
An arrangement as defined in claim 1, wherein said elastic ring has a predetermined diameter, said V-shaped edge of the other tubular member being arranged radially outwardly of a circumference corresponding to the diameter of said elastic ring and fittable onto said radially outer lip of the latter.
Claim 9
Dependent Claim
39 words
An arrangement as defined in claim 7, wherein the other tubular member has an end face axially offset from said V-shaped edge, said radially inner lip being arranged to abut against the end face of the other tubular member.
