Abstract
Abstract A tape measure casing comprises a main shell having a central hub with a cylindrical bore opening into an enlarged cylindrical recess in a side wall, and a rotatable side flange including an integral tape drum disposed coaxially about a central cylindrical pivot rotatably received in said bore of the hub. The shell and flange are held together by a clipping button having an enlarged cruciform head rotatably received in said enlarged recess, a square shank keyed in a square bore in the pivot, and elastically deformable hooking projections engaging in a hooking recess in the pivot.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A tape measure casing comprising a shell formed by first and second members defining first and second lateral walls of the casing, one of the first and second members being integral with a tape drum and being rotatably mounted relative to the other of the first and second members, the first member having a central hub integral therewith and means defining a cylindrical first centRal through bore in said hub, said bore opening into an enlarged recess in said first lateral wall, the second member having a central cylindrical pivot integral therewith, said pivot being rotatably received in said first bore of said hub and having an end thereof disposed in the vicinity of said enlarged recess of the first lateral wall, means defining a noncylindrical second central bore in said end of the pivot, means defining at least one hooking recess in said second bore, and a clipping button for holding said first and second members together, said button including a head rotatably received in said enlarged recess in said one wall, a non-cylindrical shank keyed in said second bore, and at least one elastically deformable projection engaged in said at least one hooking recess in said second bore.
Claim 2
Dependent Claim
200 words
A tape measure casing comprising a shell formed by first and second members defining first and second lateral walls of the casing, one of the first and second members being integral with a tape drum and being rotatably mounted relative to the other of the first and second members, the first member having a central hub integral therewith and means defining a cylindrical first centRal through bore in said hub, said bore opening into an enlarged recess in said first lateral wall, the second member having a central cylindrical pivot integral therewith, said pivot being rotatably received in said first bore of said hub and having an end thereof disposed in the vicinity of said enlarged recess of the first lateral wall, means defining a noncylindrical second central bore in said end of the pivot, means defining at least one hooking recess in said second bore, and a clipping button for holding said first and second members together, said button including a head rotatably received in said enlarged recess in said one wall, a non-cylindrical shank keyed in said second bore, and at least one elastically deformable projection engaged in said at least one hooking recess in said second bore.
Claim 3
Dependent Claim
58 words
A tape measure casing according to claim 1, in which said first member forms a main shell of the casing including a peripheral edge wall integral with said first lateral wall and means defining a tape withdrawal aperture in said peripheral edge wall, said second member being in the form of a flange integral with the tape drum.
Claim 4
Dependent Claim
64 words
A tape measure casing according to claim 1, in which said second bore is of square cross-section, said clipping button having a shank of square cross-section slightly smaller than that of said second bore, said shank extending to an end and being split from said end over part of its length to form two elastically deformable tongues each having an outwardly directed hooking projection.
Claim 5
Dependent Claim
47 words
A tape measure casing according to claim 3, in which said square second bore is extended towards said second lateral wall by a cylindrical bore of greater diameter than the edge of the square bore, said hooking recess including a shoulder joining the square and cylindrical bores.
Claim 6
Dependent Claim
29 words
A tape measure casing according to claim 1, in which said hub has a free end including a plurality of elastically deformable tonques elastically gripping and braking said pivot.
Claim 7
Dependent Claim
24 words
A tape measure casing according to calim 2, comprising means defining a plurality of eccentric finger-receiving recesses in the external surface of said flange.
Claim 8
Dependent Claim
24 words
A tape measure casing according to calim 2, comprising means defining a plurality of eccentric finger-receiving recesses in the external surface of said flange.
Claim 9
Dependent Claim
48 words
A tape measure casing according to claim 6, comprising means defining a plurality of openings in said flange bounded by an annular outer edge of the flange and by a plurality of arms extending generally radially to said annular edge, said finger-receiving recesses being disposed in said arms.
Claim 10
Dependent Claim
28 words
A tape measure casing according to claim 1, in which said tape drum includes means defining a slot engaging with a transversally slotted end of a measuring tape.
