Abstract
WRIST BAND
ABSTRACT OF THE DISCLOSURE
An identity band which comprises an elongated strap and a latch which forms a slot through which the strap is pushed to form the band into a loop. The strap has a series of stop surfaces alternating with a series of camming surfaces and within the slot there is a latching element.
As the strap is pushed through the slot to form the loop, the camming surfaces in turn cam the latching element to one side. The stop surfaces are arranged so that, if an attempt is made to pull the strap in the opposite direction through the slot, one of them engages with the latching element to prevent such movement of the strap. In one form the camming and stop surfaces are the surfaces of ratchet-like teeth and in another form the surfaces are the transverse edges of apertures formed in the strap. The latch element is wedge-like and mounted at its thicker end. The band is formed so that it can be written on or can have a label adhered thereto. The written on portion or label can be covered by a transparent plastics sleeve. Alternatively, the sleeve may hold a loose label in place. These arrangements permit material identifying the patient to be carried by the band.

: . .. ~.
...
. .
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 constitu-ting a stop face, and a la.tch portion adjacent one end of the band, the latch portion including a latch portion base and an arch ~ormation 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 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 o-E 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 tn 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 wristband into a loop, engagement between said latchin~ element and any one of said stop faces preventing withdrawal of the strap portion from the slot in the opposite direction.
The strap portion can be channel-shaped and comprise a base and two side flanges, said apertures being in the base.
Preferabl~ the planes in which said transverse walls of the apertures lie interesect t~le planes of the major faces - : . . : :, : ~ . ..: . .
;, ~ . , : . , , ~9~
of said strap portion at angles other than right angles.
Furthermore, each latching element can be a wedge which enters each aperture in turn as the apertures pass through said slot in said one direction, each camming face camming the element out of the aperture in which it has been received while the strap continues to move in said one direction, and the stop ~aces serving to force said element into one of said apertures upon the strap portion being displaced in said opposite direction. ~`
The wristband is pre~erably a one-piece injection moulding and can include a portion having a rough surface, which rough sur~aced portion is desirably between said strap portion and said latch portion and at which region the wristband is wider than elsewhere.
For a better understanding of the present inven-tion, and to show how the same may be carried into effect, reference will now be made, by way of example, to th~
accompanying drawings, in which:
Figure 1 is a pictorial view of an identification band embodying the invention;
Figure 2 is a side elevation of the identification band o~ Figure l;
Figure 3 is a section, to a larger scale, taken on line X-X of Figure l; and Figuxe 4 is a section, also to a larger scale, on the line XI-XI of Figure 2, ~igures 3 and 4 showing the identification band formed into a loop.
39S~
The identification band illustrated includes a strap portion 10, a portion 12 for carrying information, and a latch portion 14 for holding the band in a closed loop. The portion 14 is adjacent one end of the band.
Normally the band is placed around the wrist of the wearer but could encircle an ankle.
The free end of the strap portion 10 is shaped so as to provide a round ended cone 16 which, as will be more fully explained hereinafter, facilitates engagement of the strap portion with the latch portion 14. setween the cone 16 and the portion 12 the strap portion 10 i5 of channel-section having a base 18 and two upstanding side flanges 20. Both ends of each side flange 20 merge with the base 18 by way of ramps 22.
The portion 12 is of flattened xectangular cross-section and the function of this portion will be described in more detail hereinafter. The portion 12 is wider than any other part of the band.
The portion 12 lies between the strap portion 10 and a neck 26 which joins the latch portion 14 to the portion 12.
The base 18 is formed with a series of spaced apertures 56, most of the apertures being equally spaced from one another but there being three apertures 56 .. . : .: . - -:.
~39~
adjacent the portion 12 which are closer together than theremainder.
Each aperture 56 is bounded by laterally spaced, longitudinally extending side walls 58 and transverse walls 60 and 62. The walls 60 and 62 are inclined with respect to the upper and lower faces of the base 18 as can best be seen in Figure 3 and thus intersect the planes of the major faces of the strap portion at angles other than right angles.
The latch portion 14 includes a latch portion base 64 which is somewhat wider than the neck 26 and an arch formation 66 which, together with the base 64, defines a latching slot 68 for receiving the strap portion 10.
The arch formation 66 comprises legs 70 joined by a cross piece 72, a block 74 being provided on the underside of the cross-piece 72.
A centrally disposed, rectangular aperture 76 is provided in the base 64, and a latching element in the form of a flexible wedge 78 protrudes from the centre of that one of the transverse walls of the aperture 76 which is remote from the strap portion 12. The wedge 78 slopes upwardly towards the block 74 and the upper tip of the wedge 78 lies close to the undexside of the block 74.
To secuxe the i~entity band around a wrist or ankle, the band is formed into a loop with the smooth - ' ' ' ~ ' :
:
.
. ' ' " , ' -: :
5~
surface thereof ~the lower surface in Figu~e 2) against the user's skin. This is diagrammatically shown by the chain-dotted line in Figure 3. The cone 16 is pushed through the slot 68 which is bounded by the base 64, the legs 70 and the cross piece 72. As will be clearly seen from Figure 4, the shape of the slot 68 is compatible with the cross-sectional shape of the strap portion 10.
As the strap portion 10 is pushed through the slot 68, the wedge 78 is cammed downwardly away from the block 74 out of the slot 68 and into the aperture 76 to permit free passage of the strap portion 10. ~s the aperture 56 closest to the cone 16 comes into co-operating relationship with the wedge 78, the wedge springs into this aperture. As the strap portion 10 is pulled further through the slot 68, as shown by the arrow X in Figure 3, the wall 62 cams the wedge 78 downwardly out of the aperture 56 into which it has sprung.
When the desired tightness of the band around the wrist or ankle has been achieved, the part of the strap portion 10 which protrudes from the slot 38 and overlies the neck 26 and the portion 12 is cut off. ~ny attempt to loosen the band, by pulling the strap portion in the direction of the arrow ~ in Figure 3, causes engagement between the face 60 of the aperture 56 in which the wedge 78 is entered and the undersurface of -the wedge. The wedge is thus forced upwardly against the block 74 and hence, 1' ' ': , " "
'~ : ` ';` ~, ~995~g again as will clearly be seen fxom Figure 3, the strap portion cannot be removed withou-t destroying the wedge 78 or tearing the strap portion 10. The position shown in Figure 3 is that in which an attempt has been made to pull-back the strap portion 10. The band can only be removed by cutting.
A stop can be pro~ided at 80. This stop is only shown in Figure 2. Once the protruding part of the strap portion has been cut off, the cut end is tucked behind the stop 80 to prevent the band being pulled tighter.
Information concerning the patient is carried on the portion 12. The band illustrated is intended to be injection moulded and one surface of the portion 12, that which faces outwardly, can be rough so as to enable information to be written directly onto ito This can be achieved by sandblasting the respective surface of the mould.
As an alternative to writing on the portion 12, a rectangular label of paper, card or cloth can be secured eg gummed to the portion 12 and a transparent plastics sleeve slipped over the card or paper to protect it. The labels can be provided in reel foxm on a backing sheet, peeled-off and applied to the bands.
Suitable materials ~o~ the one-piece injection-moulded identification band describea are polypropylene and polyethylene. Nylon and rubber are also suitable materials.
