Abstract
Abstract A band clip includes a rotatably mounted screw which meshes wormwise with a threaded portion of the band. The screw is provided with a frusto-conical portion and the mounting for the screw presents an inclined surface which co-operates with the frusto-conical portion in such a way that, when the band is in an operative condition, co-action between the frusto-conical portion and the inclined surface biases the screw into engagement with the threaded portion of the band.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
In a band clip of the kind which includes a screw rotatably mounted, for threaded engagement with one end portion of the band, in a mounting fixedly associated with the other end portion of the band, the improvement wherein: a. the mounting includes a wall which presents a surface for engagement with the screw, said surface being inclined to the axis of the screw, b. the screw includes a face co-operating with said inclined surface, co-action between said inclined surface and said face of the screw, when the band is in an operative condition with the end portions thereof in overlapping relation, resulting in biasing of the screw towards said one end portion of the band, and c. the screw and the mounting having co-operating means which retain the screw in the mounting and enable tilting of the screw out of said threaded engagement with said one end portion so that relative sliding movement between the end portions of the band can take place.
Claim 2
Dependent Claim
164 words

Claim 3
Dependent Claim
42 words
A band clip according to claim 1 in which the screw is provided with a frusto-conical portion at one end thereof, which portion affords said face of the screw, the generatrix of the frustro-conical portion of the screw being a straight line.
Claim 4
Dependent Claim
37 words
A band clip according to claim 2 in which a spigot projects from the smaller diameter end of the frusto-conical portion of the screw and is received in an opening in the wall presenting said inclined surface.
Claim 5
Dependent Claim
41 words
A band clip according to claim 1 in which the screw is provided with a frusto-conical portion at one end thereof, which portion affords said face of the screw, the generatrix of the frusto-conical portion of the screw being a curve.
Claim 6
Dependent Claim
37 words
A band clip according to claim 4 in which a spigot projects from the smaller diameter end of the frusto-conical portion of the screw and is received in an opening in the wall presenting said inClined surface.
Claim 7
Dependent Claim
35 words
A band clip as claimed in claim 1 in which the mounting is formed integrally from the band and includes a pair of spaced, parallel side walls interconnected by said wall presenting said inclined surface.
Claim 8
Dependent Claim
73 words
A band clip according to claim 1 in which the mounting is constituted by a U-shaped strip of metal comprising a pair of spaced limbs interconnected by a bight portion, said bight portion constituting said wall presenting said inclined surface and said limbs providing side walls of the mounting, the mounting being secured to said other end portion of the band with the limbs thereof extending laterally of a surface of the band.
Claim 9
Dependent Claim
36 words
A band clip according to claim 7 in which the free ends of said limbs straddle said one end portion of the band and are secured in underlying relationship with a further surface of the band.
