Identity band

Claim 2

Claim 3

An identity band according to claim 1, in which said latching element is in the form of a double wedge comprising a first portion adjacent said one transverse wall and a second portion extending from said first portion, the included angle between the converging faces of the first portion being greater than the included angle between the converging faces of the second portion.

Claim 4

A band according to claim 2, in which said arch formation and one of said major faces of said strap portion are on the side of the band which is directed outwardly when it is formed into a loop and the other major face of said strap portion is directed inwardly in this condition, the included angle between each camming face and said one major face being less than the included angle between each stop face and the other major face.

Claim 5

An identity band capable of being formed into a loop comprising an elongate strap portion having a series of apertures therein, each aperture having two spaced apart transverse walls, one transverse wall of each aperture constituting a camming face and the other transverse wall of each aperture constituting a stop face, and a latch portion adjacent one end of the band, the latch portion including a latch portion base and an arch formation including legs normal to the latch portion base and a cross-piece parallel to and spaced from the latch portion base, said legs, base and cross-piece defining a latching slot for receiving said strap portion, said latch portion base having an aperture therein and there being a displaceable latching element protruding from that one of the transverse walls of this aperture which is remote from said strap portion, said latching element extending into said slot and being in the form of a double wedge comprising a first portion adjacent said one transverse wall and a second portion extending from said first portion, the included angle between the converging faces of the first portion being greater than the included angle between the converging faces of the second portion and the thicker end of the double wedge being adjacent said one transverse wall, and said camming faces serving in turn to deflect said latching element out of said slot and into said aperture in said base while said strap portion is being passed through said slot in one direction to form the band into a loop, engagement between said latching element and any one of said stop faces preventing withdrawal of the strap portion from the slot in the opposite direction, a portion of the band being adapted to receive identification information.

Claim 6

An identity band capable of being formed into a loop comprising an elongate strap portion having a series of apertures therein, each aperture having two spaced apart transverse walls, one transverse wall of each aperture constituting a camming face and the other transverse wall of each aperture constituting a stop face, and a latch portion adjacent one end of the band, the latch portion including a latch portion base and an arch formation including legs normal to the latch portion base and a cross-piece parallel to and spaced from the latch portion base, said legs, base and cross-piece defining a latching slot for receiving said strap portion, said latch portion base having an aperture therein and there being a displaceable latching element protruding from that one of the transverse walls of this aperture which is remote from said strap portion, said latching element extending into said slot and being in the form of a double wedge comprising a first portion adjacent said one transverse wall and a second portion extending from said first portion, the included angle between the converging faces of the first portion being greater than the included angle between the converging faces of the second portion and the thicker end of the double wedge being adjacent said one transverse wall, and said camming faces serving in turn to deflect said latching element out of said slot and into said aperture in said base while said strap portion is being passed through said slot in one direction to form the band into a loop, engagement between said latching element and any one of said stop faces preventing withdrawal of the strap portion from the slot in the opposite direction, a portion of the band being adapted to receive identification information.

Claim 7

An identity band according to claim 4, in which the surface of the latching element facing said cross-piece is planar, the surface facing said aperture in the latch portion base changing direction where said first and second portions merge.

Claim 8

An identity band capable of being formed into a loop comprising an elongate strap portion having opposed major faces and a series of apertures therein, each aperture having two spaced apart transverse walls, one transverse wall of each aperture constituting a camming face and the other transverse wall of each aperture constituting a stop face, the planes in which said transverse walls of the apertures lie being skew to the planes of the major faces of said strap portion and said camming and stop faces being skew to one another, and a latch portion adjacent one end of the band, the latch portion including a latch portion base and an arch formation including legs normal to the latch portion base and a cross-piece parallel to and spaced from the latch portion base, said legs, base and cross-piece defining a latching slot for receiving said strap portion, said latch portion base having an aperture therein and there being a displaceable latching element protruding from that one of the transverse walls of this aperture which is remote from said strap portion, said latching element extending into said slot, and said camming faces serving in turn to deflect said latching element out of said slot and into said aperture in said base while said strap portion is being passed through said slot in one direction to form the band into a loop, engagement between said latching element and any one of said stop faces preventing withdrawal of the strap portion from the slot in the opposite direction, a portion of the band being adapted to receive identification information.

Claim 9

An identity band capable of being formed into a loop comprising an elongate strap portion having opposed major faces and a series of apertures therein, each aperture having two spaced apart transverse walls, one transverse wall of each aperture constituting a camming face and the other transverse wall of each aperture constituting a stop face, the planes in which said transverse walls of the apertures lie being skew to the planes of the major faces of said strap portion and said camming and stop faces being skew to one another, and a latch portion adjacent one end of the band, the latch portion including a latch portion base and an arch formation including legs normal to the latch portion base and a cross-piece parallel to and spaced from the latch portion base, said legs, base and cross-piece defining a latching slot for receiving said strap portion, said latch portion base having an aperture therein and there being a displaceable latching element protruding from that one of the transverse walls of this aperture which is remote from said strap portion, said latching element extending into said slot, and said camming faces serving in turn to deflect said latching element out of said slot and into said aperture in said base while said strap portion is being passed through said slot in one direction to form the band into a loop, engagement between said latching element and any one of said stop faces preventing withdrawal of the strap portion from the slot in the opposite direction, a portion of the band being adapted to receive identification information.

Claim 10
