Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
200 words
The combination of a tape reel hub and a device for clamping the terminal end portion of a tape within a recess defined within said tape reel hub, comprising: first fastening means mounted upon said tape reel hub; a base member defined upon said device; a pair of legs extending substantially radially inwardly from said base member toward said tape reel hub; second fastening means defined upon said pair of legs of said device for operatively engaging said first fastening means of said tape reel hub; and a bridge member connecting the radially inner ends of said pair of legs, the radial distance defined between said device base member and said bridge member being greater than the effective radial depth of said recess so as to cause circumferential expansion of said clamping device legs and said second fastening means, in response to radial contraction of said clamping device as a result of engagement between said clamping device bridge member and the radially inner portion of said hub defining said recess as said clamping device is radially inserted into said tape reel hub recess, whereby said second fastening means of said device operatively engage said first fastening means of said hub.
Claim 2
Dependent Claim
200 words
The combination of a tape reel hub and a device for clamping the terminal end portion of a tape within a recess defined within said tape reel hub, comprising: first fastening means mounted upon said tape reel hub; a base member defined upon said device; a pair of legs extending substantially radially inwardly from said base member toward said tape reel hub; second fastening means defined upon said pair of legs of said device for operatively engaging said first fastening means of said tape reel hub; and a bridge member connecting the radially inner ends of said pair of legs, the radial distance defined between said device base member and said bridge member being greater than the effective radial depth of said recess so as to cause circumferential expansion of said clamping device legs and said second fastening means, in response to radial contraction of said clamping device as a result of engagement between said clamping device bridge member and the radially inner portion of said hub defining said recess as said clamping device is radially inserted into said tape reel hub recess, whereby said second fastening means of said device operatively engage said first fastening means of said hub.
Claim 3
Dependent Claim
44 words
The combination as set forth in claim 1, further comprising: at least one re-entrant portion defined within said device bridge member; and at least one projection defined within said hub recess for engaging said at least one re-entrant portion of said device bridge member.
Claim 4
Dependent Claim
39 words
The combination as set forth in claim 1, wherein: said first fastening means of said tape reel hub extend circumferentially inwardly toward each other; and said second fastening means of said device extend circumferentially outwardly away from each other.
Claim 5
Dependent Claim
50 words
The combination as set forth in claim 3, wherein: said base member has portions which extend circumferentially outwardly away from each other; said base member portions are radially spaced from said second fastening means; and said first fastening means are interposed between said second fastening means and said base portions.
Claim 6
Dependent Claim
36 words
The combination as set forth in claim 1, wherein: said base member of said device comprises a circumferential portion of said tape reel hub when said device is fully inserted within said tape reel hub recess.
Claim 7
Dependent Claim
17 words
The combination as set forth in claim 1, wherein: said legs are integral with said base member.
Claim 8
Dependent Claim
19 words
The combination as set forth in claim 1, wherein: said bridge member is integral with said pair of legs.
Claim 9
Dependent Claim
24 words
The combination as set forth in claim 1, wherein: said pair of legs, said base member, and said bridge member are integrally formed together.
