Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
A fastener, for reception in a hole in a panel to secure a sealing strip to the panel, comprising a generally U-shaped member of spring metal, the member having a pair of arms which extend substantially parallel away from a bight portion of the member for a first part of their length and then diverge for a second part of their length, the free ends of the arms being formed with outwardly extending ears and with inwardly extending teeth to grip a sealing strip, the first parts of the arms being formed with first outwardly extending projections spaced from the junction between the first and second parts of the arms by a distance substantially equal to the thickness of a panel with which the fastener is to be used, and the second parts of the arms being formed with second outwardly extending projections spaced from the ears of the arms by a distance substantially equal to the thickness of the panel with which the fastener is to be used.
Claim 2
Dependent Claim
169 words
A fastener, for reception in a hole in a panel to secure a sealing strip to the panel, comprising a generally U-shaped member of spring metal, the member having a pair of arms which extend substantially parallel away from a bight portion of the member for a first part of their length and then diverge for a second part of their length, the free ends of the arms being formed with outwardly extending ears and with inwardly extending teeth to grip a sealing strip, the first parts of the arms being formed with first outwardly extending projections spaced from the junction between the first and second parts of the arms by a distance substantially equal to the thickness of a panel with which the fastener is to be used, and the second parts of the arms being formed with second outwardly extending projections spaced from the ears of the arms by a distance substantially equal to the thickness of the panel with which the fastener is to be used.
Claim 3
Dependent Claim
30 words
A fastener as claimed in claim 1, in which the first and second outwardly extending projections are in the form of barbs struck out from the arms of the fastener.
Claim 4
Dependent Claim
41 words
A fastener as claimed in claim 1, in which the first outwardly extending projections are pressed-out portions of the first arm parts, and the second outwardly extending projections are in the form of barbs struck out from the second arm parts.
Claim 5
Dependent Claim
41 words
A fastener as claimed in claim 1, in which one arm carries one tooth and the other arm carries two teeth arranged to pass on either side of the one tooth of the one arm as the arms are closed together.
Claim 6
Dependent Claim
39 words
A fastener as claimed in claim 4, in which the one arm carries two second outwardly extending projections one at each side of the second arm part, and the other arm carries a sIngle, central second outwardly extending projection.
Claim 7
Dependent Claim
19 words
A fastener as claimed in claim 1, in which the ears extend substantially perpendicularly from the second arm parts.
Claim 8
Dependent Claim
23 words
A fastener as claimed in claim 1, in which each ear and the associated second arm part include an angle greater than 90*.
