MO C£AM\ I k~ U--I-t %tt-1: Actual Inventors: JOHN BENNETT and HOWARD KENNETH SCHULZE Address for Service: -GOLLASN- &ACOA4 7-Kihg VZ C Invention Titl: PAPER RETAINING MEANS W'lHarn-Street-Adelaide-SA-5000- Details of Associated Provisional Applications: AUSTRALIAN Patent Application No. PK7702 dated 12th August 1991 The following statement is a full description of this invention, including the best method of performing it known to us: i t 2 This invention relates to paper retaining means.

It is known to use two members one of which has a base from which extends two fingers. The two fingers pass through respective apertures within a support sheet and through apertures in papers to be held and subsequently engaged with a clamping member. It is an aim of the invention to provide an improved paper retaining means or at least provide the public with a useful alternative.

According to one aspect of the invention there is provided a paper retaining means including: a base; two fingers having teeth, the two fingers extending from the base and being spaced apart a selected distance; a clamping member having two apertures passing therethrough and being spaced apart the same distance as the selected distance of the respective fingers on the base, each of the apertures providing a passage from an underside face to an upper face of the clamping member for the respective fingers to pass therethrough; and a clip part integral with or attached to the upper face of the clamping member, the clip part having one or more teeth facing the upper face of the clamping member, and the teeth of the clip part being adapted to engage a portion of the teeth of each of the fingers.

o: 25 Alternatively, according to a further aspect of the invention there is provided S: a paper retaining means including: *a base; and two fingers having teeth, the two fingers extending from the base and being spaced apart a selected distance; a clamping member having two apertures passing therethrough and being spaced apart the same distance as the selected distance of the respective fingers on the base, each of the apertures providing a passage from an underside face to an upper face of the clamping member for the respective fingers to pass therethrough; and I 3 two clip parts integral with or attached to the upper face of the clamping member, each of the two clip parts having one or more teeth facing the upper face of the clamping member, and the teeth of each of the two clip parts being adapted to engage a portion of the teeth of a respective finger.

Suitably, the clip part or each of the clip parts include a first section extending perpendicular from the upper face of the clamping member and a cantilevered second section extending at a right angle from the first section to a free end to provide a finger ensnaring area.

The free end of each clip part may be suitably shaped/such that it has a section which extends towards the upper face of the claimping member.

Suitably, each said cantilevered second section is of a shape which inwardly tapers towards its said free end.

The cantilevered second section of one of the clip parts may suitably extend in the opposite direction to that of the cantilevered second section of the other clip part.

Suitably, there are teeth on opposite sides of each of the fingers.

"Alternatively, according to a further form of the invention there is provided a 25 paper retaining means including: a base; two fingers having teeth on opposite sides of each of the two fingers,

IIII

the two fingers extending from the base and being spaced apart a selected distance; 30 a clamping member having two apertures passing therethrough and being spaced apart the same distance as the selected distance of the respective fingers on the base, each of the apertures providing a passage ~from an underside face to an upper face of the clamping member for the respective fingers to pass therethrough; and

I

3a four clip parts integral with or attached to the upper face of the clamping member, two of the four clip parts being oppositely located about one of the apertures and the other two of the four clip parts being located about the other one of the apertures, each of the four clip parts having one or more teeth facing the upper face of the clamping member such that the teeth of each of the four clip parts are adapted to engage a portion of the teeth of a respective finger.

Suitably, each of the respective clip part or parts have two of said teeth facing the upper face of the clamping member.

The invention will be better understood when described with reference to a preferred embodiment which will now be described with the assistance of drawings in which: FIG. 1A is a plan view of a clamped part according to first embodiment, FIG. 1B is a sectional view through A-A' of FIG. 1, FIG 2A is a perspective view according to the first embodiment as shown in FIG. 1,

S.

••go oooo o _o .o FIG. 2B is the base part with attached fingers that is adapted to be used in conjunction with the clamped part as shown in FIGS. 1A and 2A, FIG. 3 is an underneath view of the clamped part as shown in FIGS. 1A and 2A, FIG. 4 is a plan view of a second embodiment, FIG. 5 is the underneath view of the embodiment as shown in FIG. 4, *FIG. 6 is a base part which can be used in conjunction with the second embodiment but only in respect of the outer side clips, 7 is a perspective view of a third embodiment showing specifically 10 the clamp part, and FIG. 8 is a perspective view of a clamp part joined with a base according to a fourth embodiment.

Referring in detail to the drawings there is shown, in FIGS. 1A, 1 B, 2A, 2B and 3, a clamp part 1 which is manufactured by injection moulding from a plastics material such as nylon and has a substantially rectangular shape in plan and is substantially planar in general alignment. The clamp part 1 has apertures 2 and 3 passing fully therethrough the size and location being such that fingers and 5 attached to the base part 6 can pass therethrough.

The base part 6 together with its fingers 4 and 5 is also manufactured by injection moulding from a nylon plastics material and its shape and distance apart of the fingers is such that these are compatible with the location of the apertures 2 and 3. In this way of course the fingers 4 and 5 can pass through appropriated apertures in sheets of paper, card or folders and thereby clamp the papers subsequently thereto.

On a outer side of the respective fingers 4 and 5 are teeth 7 and 8 which are adapted to interengage with teeth located at 9 beneath the right angular part defining a clip part 11.

There are two clip parts shown namely one at 11 and another at 12 each of these defining there beneath a clipping space and there is indicated by reason of the arrow shape shown at 13 in one case and 14 in the other location of the open gap side of the clipping space.

In this first example it will be seen that the clip part 11 and 12 are on the innerside with respect to the apertures 2 and 3 so that the fingers 4 and 5 in order to be capturing the clipping part will have to be bent inward and therefore to some extent cross over one another. A strengthening rib and guide is located on both sides of the base of the clamp part 1 these being shown at 15 and 16.

In the second embodiment, FIG. 4 and FIG. 5, the arrangement is the same so ~*far as a first clipping part shown at 17 and 18 is concerned but there is the addition of an outer clipping part 19 in the one instance and 20 in the other each relevant to aperture 21 in the one case and 22 in the other. In both cases, there is a tapered shape shown at 23 in the one case and 24 in the other to indicate the side that has the open aperture but otherwise the shape underneath is the same defined by a right angle part, interlocking teeth and a step as shown at 25 of FIG 3.

In the case of the third embodiment, FIG. 7, which has a clipped part on the outer side with respect to the apertures. This has the shape as shown in both of the previous embodiments, each of the clip parts being shown at 26 and 27 and having a tapered side at 28 in the one case 29 in the other to illustrate :which way the finger 30 or 31 is to be located beneath the interlocking shape.

The base of FIG. 6 should be used with the outer side clip pars so that the teeth 30 and 31 can engage the clip parts. In a further embodiment (not shown) the teeth can be located on both sides of the fingers so that the base can be used on inner or outer grips.

In FIG. 8 base part 32 is joined in typical fashion with clamp part 33. The parts are the same in each case being manufactured from injection moulded plastic and the plastics material being that which is appropriate to the application but thus far having been found to be nylon.

6 This describes the embodiments from which it can be seen how this allows for an improvement in relation to clipping systems hitherto available.

Throughout this specification the purpose has been to illustrate the invention and not to limit it.
