The present invention relates to a clip and in particular, stationery clips to be used with paper, card or the like.
Various different clips are well known for holding together a plurality of sheets of paper. Examples include a bull dog clip and the well known basic or common wire paper clip.
Clips have also been proposed for marking a particular page or a particular part of a page. For example, clips in the shape of an arrow can be used to indicate where a signature is needed. Clips are also known which have a tab portion which protrudes beyond the edge of a page or divider to which the clip has been attached. This allows a particular page or section to be easily referenced. The tab is, however, made of plastic and is only possible to be marked with a suitable water proof marker. This is inconvenient for the user if they do not have the required marker to hand.
It has also been proposed to provide clips with advertising across one of the clipping parts (WO02/28217).

Reference is now made to
The clipping part 2 has a first end 4 and a second end 6. Starting from end 4, the wire adopts a V shaped configuration 8. From the end of the V different to end 4, which extends outwardly from the end portion 4 by a small amount, a substantially rectangular portion 10 is defined which surrounds the V and ends with end portion 6 of the wire. The clipping part 2 shown in
In one embodiment, the upper surface 14 comprises paper while the rear surface 16 comprises a plastic material. As shown in
A cut 20 is provided below the V shaped portion 8 of the clip. The cut 20 is positioned so that the wire clip is not exposed by the cut. Accordingly, the cut 20 is spaced from the V shaped portion 8 of the clip 4 by a suitable distance. This cut 20 is provided through both the first layer 14 and the second layer 16. In an alternative embodiment, the cut may only extend through the first layer with the papers held by the clip being between the first and second layers.
The second layer 16 is one embodiment of the present invention is transparent. This means that the clipping part 2 may be visible. In embodiments of the invention, one or both of the layers may be transparent. This can be either the top layer 14 or the back layer 16. Likewise, one or other or both of the layers may be opaque. Again, this can be the top layer 14 or the back layer 16. The material to make the various layers can be selected as appropriate. At least one of the layers comprises a writable material, such as paper or suitably treated plastics.
It should be understood that, if in one embodiment of the invention, the material of the layer may itself be not able to be written on but a further portion is provided on that layer on which the user can write. The layers can comprise any suitable material, such as paper, card, plastic, foil, metal, metal covered plastic or any other suitable combinations thereof. In preferred embodiments of the present invention, one layer, preferably but not necessarily, layer 14 has a portion or itself is of a material on which the user can write with any suitable writing instruments such as a ball point pen, felt tip marker, pencil or the like. It is also possible that the area on which the user is to write be of a plastics material which requires a particular type of marker, such as a waterproof marking pen to write thereon. It should be appreciated that embodiments of the present invention, the user may be able to write on both sides of the clip.
The clip preferable has a portion 22 which extends above the clipping part 2. Thus, when the clip 12 is attached to a sheet of material, the portion 22 will extend from the sheet of paper and thus be visible, this portion 22 thus acts as a marker or indexing portion.
The two layers of material 14 and 16 may be blistered/hot formed about the clipping part 2. The two layers may be stuck to one another by means of an adhesive. The two layers may be stuck together using laminating techniques. Alternatively, the layers may be made of such material that the application of heat and/or pressure causes the two layers to adhere together.
It should be appreciated that the shape of the basic wire paperclip can take any suitable format. For example, the rectangular part of the clip may be replaced a U shaped portion, another V shaped portion or indeed any other suitable shape. The V shaped portion itself maybe U shaped, square, semi circular or any other suitable shape.
In use, the sheet or sheets of paper or card are inserted between the V shaped portion of the clipping part and the rectangular portion 10 of the clipping part. This is by means of the opening 20 provided in the clip 12. The tab portion 22 will protrude from the top of the sheets of paper or the like.
Reference will now be made to
The clip 50 comprises a base 52. The base 52 can take any suitable shape. In the embodiment shown in
The base 52 has an opening 54 which is generally rectangular in shape. This opening 54 can of course can any other suitable shapes such as U shaped, V shaped, square, circular etc. Extending from one side 55 of the opening 54 is a resiliently mounted or sprung tongue 56. The tongue 56 extends from side 55 and out of the plane containing the opening 54. The tongue 56 then slops downwardly into the plane containing opening 54. Thus, when the paper or the like is inserted under the tongue 56, the resiliently mounted tongue 56 will tend to push the paper or the like down into the plane containing opening 54 thus allowing the papers to be retained in place.
The base has a portion 58 extending from side 55 of the opening. Portion 58 is arranged so that when one or more papers are retained in position by the tongue 56, portion 58 will project from the papers. Portion 58 contains will have a writeable surface either from the nature of the upper layer of the material itself or because a writeable portion has been applied to this region. In some embodiments of the present invention, the clip shown in
The tongue 56 can have any suitable shape such as V shaped, U shaped, rectangular or square. The extent by which the tongue rises about the plane of opening 54 will determine how many sheets of paper or thickness of material that can be accommodated under the tongue 56.
a to 3b show a further embodiment of the invention. The user is supplied with clips 70 together with a supply of pre-cut cards 72. The clip 70 is arranged to be attached to the piece of card 72 as will now be described.
The clip can have any suitable structure. In the embodiment shown, the clip 70 has a first clipping part 74 and a second clipping part 76 which are arranged to hold material therebetween. The first and second clipping parts 74 and 76 are each generally in the shape of an “m”. The first and second clipping parts are connected at a first point 78 at the beginning of the “m” and at a second point 80 at the end of the “m”. The middle part 84 of the “m” of the first clipping part is not joined to the middle part 82 of the second clipping part 76. The middle part 84 of the first clip is arranged to define a circular part at the end thereof. The middle part 82 of the second part comprises two separate legs side by side. Thus the ends of the two legs at the bottom of the middle part are not joined together. The lowest points of the two middle parts 82 and 84 may be at the same level. This level is above the level of the base of the “m”s.
The middle part 84 of the first clipping part may be arranged to define an arc above the plane containing the clip. In this embodiment, the top of the first clipping part 74 is lower than the top of the second clipping part 76.
The card 72 has a slot 86 which is arranged to receive the clip.
