Description

DEVICE AND CONSTRUCTION OF A RING BINDER FOR INSERTION OF SHEET MATERIALS.

The present invention relates to a device for a ring binder as it appears in the ingress of the subsequent claim 1.

According to a second aspect of the invention, a construction for fastening of sheet material to the jacket of a ring binder is also described.

A ring binder comprises two plane sides, each of which are interconnected with a common spine and can be swung about this to be adjusted between an open position and a folded position. To insert sheet material, a loop system is arranged on the internal side of the spine (denoted the belly side) which can be adjusted so that the holes in the sheet material can be threaded onto the loop and be taken out again, as is well known. Synonyms for ring binder are "archive binder" or "loose leaf folder".

Existing fastening mechanisms in ring binders lead to empty binders requiring a lot of space during storage and transport, as the upright loop part prevents flat packing of several ring binders, one on top of another. Transport in large boxes of a low weight is less favourable than being able to get a larger number of binders into the same volume. Ring binders, which up until now can not be packed flat, take up a lot of space where there is a need to have a store of binders.

Another problem is that, over time, most loop mechanisms do not connect properly and slant in the opening where sheet material is to be inserted so that the sheet material gets stuck when one thumbs through the binder and the loop parts do not meet correctly when they are clamped together. Reference is made to DE 65113, GB 1452738, GB 203089, WO 2005042270, US 4,730,950 and FR 2308511 which describe prior art as it is defined in the ingress of this description.

It is an aim of the invention to provide a fastening mechanism for fastening of loose sheet material in such a ring binder, and where all the above mentioned disadvantages are eliminated.

Furthermore, it is an aim of the invention to provide a device for a ring binder so that the loop system can be folded flat to reduce the space requirement during storage and transport.

The device according to the invention is characterised in that each of the one leg ends of the loop parts is articulatedly connected to the connecting rod so that each loop part can be individually swung about between a fully raised position and a folded position level with the connecting element, and that the peg units each comprises two pegs mutually spaced apart which together form a U-shape, and which are set up to cooperate with the Pl-formed loop parts so that they together form the two ring loops of the binder for fastening of the sheet material to the binder, as is described in the characteristics in claim 1. The Pl-formed loop parts can be individually articulatedly connected with their respective connecting rod and can be swung about an axis approximately perpendicular to the longitudinal direction of the connecting element so that they can be folded in a position for flat packing, storage and transport.

The one leg parts of the Pl-formed loop and the pegs of the peg units are preferably set up to be glidingly connected so that 1) the loop can glide down to a lowest position in relation to the side of the binder to form an unbroken ring with the U-shaped parts, or 2) be pushed upwards to form an opening in the ring for insertion of sheet material or 3) be released completely for emptying or flat packing of the binder. Furthermore, the Pl-formed loop parts can comprise hollow leg parts set up to be threaded down onto the upwardly protruding pegs. In addition, the one, or both, pegs can comprise a coil spring which is threaded on, to contribute to the loops being lifted off the pegs when the elements shall be taken apart, or a second spring mechanism is arranged in the form of a leaf spring, a coil spring or a lifting and lowering mechanism connected to the connecting rod. Furthermore, the two upwardly extending pegs are fitted to each end of a cross- rod, respectively, to form a U-shaped set of pegs, and the cross-rod of the set of pegs can rotate between a folded position for flat packing, storage and transport and an upright using position to work with the Pl-formed loop part so that they together form the two ring-loops for fastening of the sheet material to the binder.

According to a preferred embodiment, when the two sets of loops are joined with the help of the gliding mechanism, the U-shaped parts can not be swung to the side and the loops can not rotate about a vertical axis as a consequence of the intermediate rod and the axial displacement of the articulated components. Furthermore, according to a preferred embodiment, each end of the connecting rod of the Pl-formed loop parts can comprise a through-bore formed such that when the n-loop parts are swung perpendicularly to the connecting rod, the bore of the n-loop part is level with said through-bore, and a peg can be led upward through said through-bore and further into the leg of the loop. Embodiments appear in the dependent claims 2-8.

Consequently, with the invention a completely new construction for a fastening mechanism is provided such that an empty ring binder can be flat folded at the same time as the mechanism is very stable. With the invention the loops can be folded flat against the binder cover. Furthermore, one achieves a gliding cylinder contact in the mechanism that ensures good anchorage and precision. The loops can be taken apart so that one can, in one movement, empty a ring binder which is full of sheets of paper.

According to another aspect of the invention, a construction of a ring binder for anterior insertion of sheet material is described.

Existing archive binders can have transparent pockets for anterior insertion of paper that can be time consuming and laborious to use. It is often difficult to put paper into and take paper out of such pockets, and the paper format is not suited for printing from a standard printer from a PC. This leads to most binders being left standing with poor or unappealing labelling.

The present invention relates to an external fastening of loose sheet material which is independent of the choice of fastening solution inside the archive binder. Existing binders that are commonly known do not describe constructions for fastening of sheet material to the binder covers. Here flexible means that the sheet material can easily be inserted and removed. This implies a new principle for external insertion of sheet material in an archive binder; for decoration or information about the content of the binder. Synonyms for ring binder which are commonly used are archive binder and loose leaf binders. Reference is made to US 6,305,714, US 4,629,349 and US 5,951 ,189 which describe prior art as is defined in the introduction to this description.

The construction according to the invention is characterised by one or more band- formed fastening bodies which, at a given width, run along the outer sides of the rim edges of the ring binder to form one or more pockets for anchoring of sheet material, said band-formed fastening bodies are subjected to a tensile power when the binder is closed such that the sheet material is held firmly in the pocket. A first band-formed fastening body is preferably arranged along the upper rim of the binder and a second band-formed fastening edge along the lower rim of the binder, with there being a distance between these.

According to a preferred embodiment the fastening body is chosen from flexible materials such as foil or textiles. One or more sheet materials can emboss the outside of the binder such as its front, rear and spine, in that said fastening edges hold said embossments in place. The sheet material can comprise one or more sheets or pockets. The sheet material has preferably a height which is equal to or less than the height of the binder, but greater than the distance between said fastening edges.

The sheet materials are preferably replaceable and be inserted when the binder is open by placing them under said fastening edges. The inwardly facing part of the fastening band against the binder side can have a convex elevation to promote the clamping of the inserted sheet material. The sides of the binder preferably comprise a further number of tightening bands that are arranged across the binder surface at a distance from the edge bands, said band surfaces that face inwards into the side of the binder have a convex elevation to promote the tightening of the sheet material against the side of the binder. The construction according to the invention is characterised by the features that appear in the characteristic in the subsequent claim 9. The preferred embodiments appear in the dependent claims 10-17.

Preferably, a band-formed fastening body is arranged along the upper rim of the binder and a second band-formed fastening edge along the lower rim of the binder, with there being a distance between these. Said fastening body is preferably chosen from flexible materials such as foil or textiles. One or more sheet material can emboss the outside of the binder, such as its front, rear and spine, in that said fastening edges hold said embossments in place. Said sheet material can be acetate sheets which are also termed foils.

Preferably, the sheet material has a height which is equal to or less than the height of the binder, but greater than the distance between said fastening edges. The sheet material is inserted when the binder is open by placing it under said fastening edges.

In the following, the invention shall be described in more detail with reference to the figures, where:

Figure 1 shows a perspective of the Pl-formed loop part, with the loops in upright position in relation to a connecting rod. The loop part shown with the rod is loose, i.e. it does not need to be permanently fitted to the cover of the binder.

Figure 2 shows the same loop body as in figure 1 , where the two loop parts are swung down level with the connecting rod.

Figure 3 shows a receiver unit arranged to the loop body, which comprises two upright pegs fitted to a connecting strip. The figure shows the unit with the pegs upright. The receiver unit is preferably permanently fitted onto the inside of the spine of the binder.

Figure 4 shows the same as figure 2, but where the unit with the peg is folded.

Figure 5 shows the two elements in connection to an opened ring binder. The receiver unit is permanently fitted to the surface of the spine, while the loop part is shown lying loose on top of the one side of the binder. Figure 6 shows the loop part as it is being threaded down onto the upright receiver unit.

Figure 7 shows the loop part almost completely placed over the receiver unit.

Figure 8 shows how the loop part and receiver part are fitted to a ring binder and a stack of sheet material is inserted and fastened with the help of the loop part and the receiver part according to the invention.

Figure 9f shows how fastening edges for foolscap sheets are arranged on the outside and the spine of the binder for easy insertion of sheet material.

Figure 10 shows the binder without inserted sheet material (paper or acetate sheets/foils) and fully opened up and laid down flat. The figure shows how the fastening edges run along the whole length of the binder so that sheet material can be placed on both sides of the spine (i.e. the front or the rear of the binder) according to need, and also on the spine itself.

The figures 11 A, 11B and 11C show enlarged cross sections of details of the cross-shape of the band-formed fastening edge.

Figure 12 illustrates that one can choose to fold sheet material for placing in the binder spine as an alternative to placing the sheet material around the spine and further to the front and/or the rear of the outside of the binder.

Figure 13 shows the situation from figure 9 where the sheet material is inserted and the binder unfolded and placed flat on a base.

Initially, reference is made to figure 1 that shows a perspective of two fl-formed loop parts which are connected to the connecting rod 204 so that they can swing. Each loop comprises two straight, parallel legs 205 and 206 (207-208), respectively, tied together with an arch-formed part 217 and 218, respectively. The leg 205 which is connected to the rod 204 is longer than the leg 206. Together the loops 200 and 202, respectively, make said fl-form. The end of the loop leg 205 is articulatedly connected to the rod 204 so that each loop part 200 and 202, respectively, can individually be rotated 90° between an upright position (figure 1) and a folded position (figure 2) where they are approximately level with the rod 204. The distance between the anchorage points of the loops 200 and 202 to the rod 204 corresponds to the standard distance for ring binders, i.e. the distance between the holes in the sheet material that is inserted into the ring binder.

Each end of the rod 204 is formed with a hinge 215 and 216, respectively, to which the respective loops 200,202 are secured. The loop leg 205 (207) is secured to the hinge joint 215 via the one end of a plate part 210 (211) while the other end makes up a part of the hinge joint 215 (216) itself. When the loops are folded they lie approximately level with the rod 204.

When the loop is upright, the plate 210 lies down into the end of the rod so that the respective hinges define the extreme ends of the rod 204. In such a position, there is a boring (see 219 in figure 2) which runs upwards, through the end plate 212 and 213, respectively, of the rod 204 and up into the inside of the loop part. The loops 200,202 can be made from a hollow pipe which is bent or be of an originally solid material in which a hole is bored.

In this upright position, the leg parts 205,206 and 207,208, respectively, of the two hollow loop parts 200,202 are arranged to be led down onto the upright pair 305,304 and 307,306, respectively, of the peg units 300,302 that can be fitted to the side surface of the ring binder in towards the spine surface.

With reference to figure 3, the peg units comprise two units 300,302 with pairs of pegs 304,305 and 306,307, respectively, mutually spaced apart, which together form a U-shape and which are set up to cooperate with the Pl-formed loop parts so that they together form the ring loops of the binder for fastening of the sheet material to the binder.

The pegs 304/305 and 306/307, respectively, are placed upright at each end of the cross-rod 310 and 311 , respectively, which can independently rotate around a hinged joint 312 and 313, respectively, in a corresponding way to a door hinge which comprises two plate parts (for example, 310/311) that can be rotated where the one plate part (for example 310) is secured to a door frame and the other plate part (311) is fastened to the door. The pair of pegs can thereby be rotated 90° between upright position and folded position.

The two peg units 300 and 302, respectively, are fitted mutually spaced apart to a side of the binder and when they are swung into upright position, the loop elements 200 and 202, respectively, (correspondingly upright in relation to the rod

204) are threaded onto the pegs 304/305 and 306/307, respectively, in one and the same movement, as is illustrated in figure 6. In figures 7 and 8, the units are completely brought together in connection to a ring binder where a number of sheets 50 have been inserted.

In addition, the connecting rod 204 can comprise a locking mechanism 230 (a locking pin or the like) which can move a locking body (not shown) inside the rod 204. By adjusting the locking mechanism 203 to a locking position, the rod 204, and thereby the loop parts 200,202, are forced against the pegs that protrude into the loop legs 205 and 207, respectively. Thereby, the Pl-formed loops can not unintentionally come loose from the U-shaped pegs when they are joined.

With the given construction of rod between the loops, the loops can rotate freely in the articulated mechanism, they can not swing/flip to the side when the legs glide down onto the pegs lying below.

An essential feature of the invention is that the two units on both sides of the rod 204 form respective Pl-formed units which together with the two U-shaped peg units 300/302 form u + o is equal to an O (u + n = O)(can be described as an unO) which fit sheet material with holes.

Figures 4, 5 and 6 show a coil spring 320 led down onto the one peg 305 in the pair of pegs. This spring 320 will be under tension when the loops are threaded down onto the pegs and it will contribute to lift the loop mechanism off when the parts shall be taken apart, for example, to remove and insert new sheet material in the ring binder. This can also be done with the help of leaf springs and an articulated lifting and lowering mechanism.

Figure 5 shows the invention in its storage and transport position where both units are folded flat. In this position, it is clear that a stack of ring binders will take up y

much less space in a transportation box or case than the traditionally constructed ring binders.

In addition, the two U-shaped peg units and the loop unit according to the invention can also be used as completely separate loose parts independently of a ring binder to fit and arrange a stack of sheet material.

Consequently, a solution is provided where the loop mechanism comprises a basic set of U-shaped peg units articulated to be laid flat along the side of the binder, but when in an upright position forms an anchoring point for vertically standing n-formed loops which are, in the basic set, articulatedly connected to a horizontal connecting rod. The Pl-formed loops can, as the U-shaped pegs, be placed flat in position to be flat packed for transport and storage. The axial displacement between the articulated components ensures stability when the U- shaped pegs and the n-formed loops are placed together to form a common ring for insertion of loose sheet material.

In this description the invention is described in connection to ring binders with two loops for fastening of sheet material with two holes. It will be clear that the device can easily be used for binders with four loop units to fasten sheet material with four holes.

Construction for fastening of sheet material.

With reference to the figures 9-13, a ring binder 10 comprises two plane sides 16 and 18, respectively, and a spine 20. With regard to a preferred embodiment, the ring binder is formed with an external edge or pocket 14 that runs along the upper rim 30 and the lower rim section 32, and also over its spine 20. Sheet material 40 of A4 size or other sizes, can be placed in the pocket 14.

An outermost layer of a band-formed foil or textile 12 is folded back to form the pocket/fold 14 before it runs further on the inside of the binder. In this pocket 14 sheet material can be inserted as paper alone, as folded paper if the sheet material is thin and unsteady, or as paper in standard commercially available plastic pockets for fastening inside the binders such as paper in plastic foil or with especially adapted plastic foil covering. Figure 10 illustrates with arrows 15 how the band is easily lifted up for fitting of foil sheets. When the binder is shut, the band 12 is subjected to tensile force that leads to the band being tightened in against the binder surfaces 16,18,20 as is shown in figure 1. This leads to the inserted sheet material also being clamped and held firmly in the pocket 14 between the inside of the band 12 and the plane side surface of the binder. In other words, the fastening edge will lie tightly as a consequence of the tension that arises in the closing of the binder, as can be seen in figure 9.

When the binder is opened completely as shown in the figures 10 and 12-13, the band is sufficiently loose so that the sheet material can be removed and be inserted.

The figures 11A-B-C show, in enlarged detail, a cross section of the lower edge surface 32 of a binder side around which the band is fastened. The band 12 forms a U-shape which is placed around the binder rim 32. An outwardly facing flap 12' forms said pocket 14 when the binder is opened (figure 10). As shown in figure 11 A, a sheet can now be put into the pocket 14. When the binder is closed again, the band 12,12' is tightened and forces the edge of the sheet 14 in towards the side surface 118 of the binder 18 as shown in figure 11 B.

Initially, a band of a given width is used to form a pocket 14 as the inside of the band that faces the binder surface is plane. The band can have a thickness of 1-5 mm and a width of 0.5-4 cm. A width of the order 2-3 cm can be suitable. The bands (122 in figure 9) that run over the middle of the surfaces of the binder can have a width of about 1 cm and can, if necessary, comprise a thinner elastic band.

A cross section of a preferred embodiment of the band that is placed around the upper 30 and lower 32 edge sides of the binder 18 is shown in figure 11C and is shown in said U-shape. In this embodiment the inwardly facing surface of the flap 12' has a small elevation or convex curved form 112 which will promote the inserted sheet material being held in position. The band can be made from a rigid transparent plastic foil so that the embossment (writing/picture) on the sheet material that lies down in the pocket is visible to the user.

According to a preferred embodiment of the invention the inside of the binder can, with reference to the figures 11A-11C, also comprise fitted bands for fastening of sheet material inside the binder, such as loose sheet material which temporarily must be stored inside the binder before one has access to a hole puncher. This is indicated with the pocket 214 in the figures, as the sheet material 40' can be inserted in the same way as on the front. The U-shaped band must, of course, be securely fastened to the binder at the edge marked with 32. The band can be shaped as part of the rest of the covering. On the inside, one does not get said tension effect in the band when the binder is closed, so that the fastening of sheet material on the inside must, in the main be, based on the band being elastic so that it can be pulled out from the binder surface when the sheet material is inserted under the band.

According to yet another preferred embodiment, as is shown in figure 9, the sides of the binder (both the inside and the outside surfaces of the binder) can comprise a further tightening band 122 which is arranged across the binder surface 16 at a distance from the edge bands 12. This band is fastened to the binder side 16 at the rim 123 and at the end edge at 124 of the side of the binder, but lies loose and tightens across the binder surface 16. In this case, it can be an advantage that the band surface which faces the binder surface has the convex arch-shaped described in connection with figure 11c. Several such tightening bands can be set up on a binder surface, mutually spaced apart. This will help the clamping of the sheet material that is placed at the binder surface. Said extra tightening band preferably runs from the front of the binder edge to the rear of the binder edge to give the necessary flexibility to place whole sheet material across the spine. Sheet material in the fastening edges at the top and at the bottom can be covered by a suitable rigid, transparent, plastic foil which is articulated at the edges of the spine and which will succeed in holding the sheet material in place. However, it is of no consequence if tightening bands are used to provide this additional feature.

There are few limitations to what kind of materials the external edges of the ring binders which hold the sheet material should be made from. The material must, of course, be reasonably robust and hard-wearing and be reasonably flexible so that it can be tightened when the binder is closed. Thus, the material can be any material chosen from foil, textiles, plastic, rubber, leather and cardboard. Especially preferred is foil or a rubberised textile with an adapted elasticity. The band-formed material can be of the same or different material to the binders themselves. The binders can be manufactured as a unit, for example, by plastic moulding, or the edges can be manufactured separately from the binders themselves and then stuck on by gluing, welding, laminating or similar method. In addition, the size of the binder can be adjusted to the size of the sheet material one wants to use. Thus, one can manufacture binders for sheet material of all sizes, but it is, of course, most applicable that the binder is adjusted to sheet material of standard sizes, such as the European A4 or A5 sheets, or the American letter or legal standard sizes.

As binders are somewhat taller that the sheet material that is to be placed inside them, the same sheet material which shall be used inside the binders will also fit the outside as long as the two edges are together broader than the extra height of the binders in relation to the sheet material.

All types of sheet material 18 can be used as external inserts in the archive binder, according to the user's wishes. Standard paper can, of course, be used, but also other types of sheet material, for example cardboard, laminated sheets, photographic sheets or plastic sheets are relevant for fastening to the binder.

Sheet material shaped with separate pockets, for example, from transparent plastic, can also be fastened to the binder. Paper sheets of the same or smaller size (which will not fit as inserts) can then be inserted in the plastic pockets, according to what the user would want. Sheet material can also be folded before it is used as external inserts in the archive binder, for example, to get a small strip for use on the back of the binder, as long as the resulting sheet has the required height as described above.

Sheet material can thus be placed anywhere on the outside of the binder. It will often be preferred to place sheet material on one or more of the three outside faces of the binder (front, rear and spine), but alternatively one can let sheet material extend across more than one of the faces, for example, centred on the spine, but with an extension that additionally runs over the front side and rear side.
