More particularly, this invention relates to a filing arrangement, to an accessory for a filing arrangement and to a folder for a filing arrangement. DESCRIPTION OF THE PRIOR ART Swiss Application Number CH-A-98801 discloses a folder having a pair of spiral metal tongues attached to an inner surface of the folder and a metal stirrup attached to an opposing side of the inner surface of the folder. The tongues are provided with sockets for engaging the ends of the stirrup when they are upright, so that pages which have been filed on the tongues can be transferred onto the stirrup. The folder also includes a locking strip for retaining the tongues in a bent-over configuration. DESCRIPTION OF THE INVENTION According to a first aspect of the invention, there is provided a filing arrangement which includes a folder; a pair fo filing prongs which are fixed to the folder to be received through openings defined in sheets to be filed in the folder; a base member which is fastened to an inner surface of the folder; a pair of flexible, elongate elements arranged on, and extending from, the base member, the elongate elements being displaceable between a first position in which the elongate elements extend upwardly from the base member and a second position in which the elongate elements are substantially parallel to the inner surface of the folder; a pair of engaging members, one engaging member being arranged on a free end of each elongate element and being engageable with a free end of each filing prong, the engaging members being configured so that, when the elongate elements are in their first position, one engaging member is releasably engageable with the free end of each filing prong to retain the elongate elements in a configuration in which transfer of the sheets from the filing prongs on to the elongate elements is facilitated. The elongate elements may be arranged on the base member to extend substantially at right angles to a spine of the folder when the elongate elements are in their second position. Instead, the elongate elements may be arranged on the base member to extend substantially parallel to a spine of the folder when the elongate elements are in their second position. The base member, the elongate elements and the engaging members may be of a plastics material. The elongate elements may be arranged on the base member to be pivotal with respect to the base member between the first position and the second position. The base member and the elongate elements may be discrete components. An attachment means may be arranged on the base member and the elongate elements to permit the elongate elements to be releasably attached to the base member. The arrangement may include a retaining means for retaining the elongate elements in their first position and in their second position once the elongate elements have been pivoted into their first or second positions. The retaining means may be configured so that the elongate elements can be retained in either the first position or the second position irrespective of the orientation of the base member on the inner surface of the folder. Instead of being discrete components, the base member and the elongate elements may be of a unitary, one-piece construction. In particular, the base member and the elongate elements may be a one-piece moulding. A living hinge may be defined between each elongate element and the base member so chat the elongate elements are pivotal with respect to the base member. The living hinge may be configured so that the elongate elements are biased into their second position. The arrangement may include a retaining means for retaining the elongate elements in their first position once the elongate elements have been pivoted into their first position. Each engaging member may be a socket-defining component which defines a socket which is dimensioned so that the free end of a prong can be received therein. Each socket-defining component may have a substantially rectangular, external transverse profile. A guide formation may extend from a free end of each socket-defining component. Each socket-defining component may have a substantially rectangular internal transverse profile with internal dimensions complementary to the free end of its associated filing prong. A wall of each socket-defining component may have at least one aperture defined therein. The base member may be adhered to the inner surface of the folder. Instead, the base member may be mechanically fastened to the inner surface of the folder. The base member may be rivetted to the folder. According to a second aspect of the invention, there is provided a filing accessory which includes a base member; a fastening means which is arranged on the base member to permit the base member to be fastened to an inner surface of the folder; a pair of flexible elongate elements arranged on, and extending from, the base member; and a pair of engaging members, one engaging member being arranged on a free end of each elongate element and being releasably engageable with an end of a filing prong. The fastening means may include an adhesive layer arranged on the base member to permit the base member to be adhered to the inner surface of a folder. Instead, the fastening means may include a mechanical fastening arrangement to permit the base member to be mechanically fastened to the folder. According to a third aspect of the invention, there is provided a folder for a filing arrangement, the folder including a front cover; a back cover; a pair of filing prongs extending from an inner surface of one of the covers; and a fastening means arranged on an inner surface of one of the covers for fastening a base member of a filing accessory having a pair of flexible elongate elements arranged on, and extending from, the base member, to the inner surface of said one of the covers, the fastening means and the prongs being positioned relative to each other so chat an engaging member arranged on a free end of each elongate element is releasably engageable with an end of each filing prong to retain the elongate elements in a configuration in which transfer of sheets from the filing prongs on to the elongate elements is facilitated. The prongs may extend from the inner surface of the back cover. The fastening means may be in the form of a layer of adhesive arranged on the inner surface of the front cover so that the base member can be adhered to the inner surface of the front cover. A cover strip may be arranged on the layer of adhesive to be removed by a user prior to use. The invention is now described, by way of example, with reference to the accompanying drawings.

In Figure 1, reference numeral 10 generally indicates a filing arrangement in accordance with the invention. The filing arrangement 10 includes a folder 12. A pair of metal prongs 14, shown in a folded-down position, are fixed to the folder 12, to be received through openings defined in sheets (not shown) to be filed in the folder 12. The arrangement 10 includes a filing accessory 16, also in accordance with the invention. The filing accessory 16 includes a base member or base 18. The accessory 16 also includes a pair of elongate elements, or arms 20 which are interconnected, at one end 22, via a crossmember or bridge 24, to be substantially "U-shaped". The base 18, the bridge 24 and the arms 20 are of a resiliently flexible, plastics material. An opposed end 23 of each arm 20 has a socket-defining component 26 arranged thereon which defines a socket 28 which is dimensioned so that an end (not shown) of one prong 14 is receivable in the socket 28 to be held in the socket 28. In use, the bridge 24 and the arms 20 are pivotally mounted on the base 18. The prongs 14 are attached to an inner surface 54 of a back cover 55 of the folder 12 on one side of a spine 56 of the folder 12. The base 18 is, in use, attached to an inner surface 57 of a front cover 59 of the folder 12 on an opposed side of the spine 56. The base 18 is positioned relative to the prongs 14 so that the arms 20, when connected to the prongs 14, form a smooth, self-supporting arch conducive to the transfer of sheets. The arms 20 are pivotal into a first position in which the arms 20 are oriented at about 90° relative to the inner surface 54. From this position, the arms 20 can be bent so that the ends of the prongs 14 can be received in the sockets 28. Thus, any sheets which are positioned on the prongs 14 can be transferred from the prongs 14 onto the arms 20 to facilitate removal, addition and replacement of sheets while retaining the original sequence of sheets. The arms 20 are pivotal from the first position into a second position, in which they are located adjacent the inner surface 57. A pair of adhesive strips 17 are fixed to the base 18 to permit the base 18 to be adhered to the inner surface 57 of the front cover 59. The base 18 (Figure 4) includes a base plate 19. The plate 19 has a retaining means in the form of a pair of spaced, part-circular clips 30 extending therefrom. Each clip 30 (Figure 6) defines a channel 31 having an internal, part-circular transverse profile which opens operatively upwardly. Each channel 31 is defined by a pair of curved walls 33, which are resiliently displaceable away from each other to permit an article to be urged into the channel 31. The clips 30 are positioned on opposed ends 35 of the place 19 and are coaxial. The bridge 24 has a pair of spaced, spigot pins 36 which are of circular cross section and coaxial and are positioned on a lower side 32 of the bridge 24, to be spaced from each other and from the lower side 32, and to extend towards each other. The clips 30 and the spigot pins 36 are positioned relative to each other so that each pin 36 can be retained in a clip 30. In use, the bridge 24 is urged downwardly so that each pin 36 serves to urge a pair of walls 33 apart to permit the pin 36 to be received in its associated channel 31. It will be appreciated that the orientation of the clips 30 and the pins 36 relative to each other permits pivotal movement of the arms 20 relative to the base 18. The lower side 32 of the bridge 24 defines a pair of faces 40 which are directed towards each other. Each pin 36 extends from one face 40 to define a shoulder 42 between each pin 36 and its associated face 40. The faces 40 are positioned so that, when the pins 36 are in position, each face 40 abuts a complementary face 44 of its associated clip 30. Each face 40 has a wedge shaped projection or tooth formation 46 (Figure 8) extending therefrom. The formation 46 is positioned on each face 40 so that a vertex 48 defined by the formation 46 is parallel to the arms 20 (Figures 9 and 10). Each complementary face 44 of the clips 30 has three wedge-shaped recesses 50 defined therein (Figures 5 and 6). The distance between the faces 40 is substantially equal to that of the faces 44. Thus, when the spigot pins 36 are clipped into the clips 30, each face 40 will bear against a complementary face 44. It will be appreciated that the projections 46 and the recesses 50 will serve to retain the arms 20 in certain positions. A vertex 52.1 of one of the recesses 50.1 on each face 44 is oriented at about 90° to the inner surface 54 of the folder 12, in use. Thus, when the formations 46 are received in the recesses 50.1, the arms 20 will be retained in the first position. Another recess 50.2 on each face 44 has a vertex 52.2 which is positioned so that, when the formations 46 are received within the recesses 50.2, the arms 20 will be held in their second position. A further recess 50.3 on each face 44 is positioned to be diametrically opposed to the recess 50.2 and has a vertex 52.3. Thus, even if, on assembly by a user, the base 18 is rotated through 180°on the front cover 59, the arms 20 can still be retained in their second position. This facilitates adhesive fixing of the base 18 to the cover 59. The arms 20, the bridge 24 and the spigot pins 36 are of a unitary, one-piece moulding. The base 18 is also of a unitary, one-piece moulding. The resilience of the material permits a user to remove the arms 20 from the base 18 by simply pulling the arms 20 away from the base 18. This will cause the pins 36 to act against the walls 33 to displace the walls 33 away from each other, so that the pins 36 can be withdrawn from the channels 31. Each component 26 has a rectangular, external transverse profile. Further, each component 26 has a rectangular, internal transverse profile, with internal dimensions complementary to the end of its associated prong 14. It will be appreciated that this, together with the fact that the components 26 are of a resiliently flexible, plastics material will facilitate gripping of each prong 14 by the components 26. It will be appreciated that the positioning of the accessory 16 relative to the prongs 14 is important. Thus, the accessory 16 can be supplied together with a template (not shown) which can be positioned on the binder of the combination to facilitate optimal positioning of the base 19 on the cover 59. A further example of the socket-defining component 26 is shown in Figure 11. In this example, the component 26 is provided with a guide formation 62 which is defined by a portion 64 of the component 26. It will be appreciated that an end 66 of the component 26 has a pair of opposed longer edges 68 and a pair of opposed shorter edges 70. The portion 64 defining the guide formation 62 has one of the longer edges 68.1 which extends beyond the other longer edge 68.2. Thus, insertion of a prong 14 into each component 26 is facilitated. In Figure 12, reference numeral 72 generally indicates a second embodiment of part of an accessory for a filing arrangement. With reference to Figures 1 to 11, like numerals refer to like parts, unless otherwise specified. Instead of the bridge 24 and the associated components, the base 18 and the arms 20 are of a one-piece moulding. A living hinge 74 is defined at the end 22 of each arm 20 to provide pivotal movement in the directions indicated by the arrow 76. Each living hinge 74 is formed by a region 78 of reduced thickness. Each living hinge 74 is configured so that the arms 20 are biased into their second position. In Figure 13, there is shown the base 18 secured to the front cover 57 of the folder 12 via a pair of rivets 80. The rivets 80 are received through openings 82 defined in the base 18 and in the folder 12. In Figures 14 and 15 , reference numeral 90 generally indicates a third and fourth embodiment, respectively, of a filing accessory, in accordance with the invention. With reference to Figures 1 to 13, like numerals refer to like parts, unless otherwise specified. The arms 20 of the accessory 90 are parallel to the spine 56 of the folder 12 when the accessory 90 is fastened to the folder 12. Thus, the accessory 90 is defined by a moulded length 92 of plastics material. It follows that a plurality of the accessories 90 can be moulded in a side-by-side manner to minimise wastage of mould space. Each arm 20 is connected to the base 18 via a living hinge 74. In Figure 14, each arm 20 has an inner portion 94 which is connected to the base 18. Each inner portion 94 has a flat, rectangular profile so that the inner portion 94 has a pair of opposed, broad sides 96 and a pair of opposed narrow sides 98. Each inner portion 94 is oriented so that, when the arms 20 are in their second position, one of the broad sides 96 of each inner portion is positioned adjacent the inner surface 54 of the folder 12. Each arm 20 has an outer portion 100 which extends from the inner portion 94. Each outer portion 100 has a flat, rectangular profile so that the outer portion 100 has a pair of opposed broad sides 102 and a pair of opposed narrow sides 104. Each outer portion 100 is oriented so that, when the arms 20 are in their second position, one of the narrow sides 104 of each outer portion 100 is positioned adjacent the inner surface 54 of the folder 12. It will be appreciated that bending of the inner portions 94 in a plane at right angles to the spine 56 is inhibited while bending of the outer portions 100 in the same plane is facilitated. It follows that, when the arms 20 are in their first position, movement of the sheets over the inner portions 94 is facilitated. Further, the relative orientations of the inner portions 94 and the outer portions 100 facilitate the correct orientation of the components 26 for insertion of the prongs 14. Instead of the inner and outer portions 94, 100, the accessory 90 can have arms 20 with a circular cross section (Figure 15). This also facilitates correct orientation of the prongs 14. The accessory 90 also includes the retaining means which is in the form of a clipping formation (not shown). The clipping formation is configured to retain the arms 20 of the accessory 90 in their first position. Each socket-defining component 26 has a wall 104. Each wall 104 has a pair of opposed, off-set apertures 106 defined therein. Those skilled in the art of moulding plastics will appreciate that this facilitates moulding of the socket-defining components 26. In Figure 16, reference numeral 110 generally indicates a folder in accordance with a third aspect of the invention, for a filing arrangement. With reference to Figures 1 to 15, like numerals refer to like parts, unless otherwise specified. The folder 110 includes the filing prongs 14 extending from the inner surface 54 of the back cover 55. The folder 110 also includes an adhesive fastener 112 which is positioned on the inner surface 57 of the front cover 59 of the folder 110. The fastener 112 comprises an adhesive layer 118 (Figure 17) which is attached to the inner surface 57 of the front cover 59 on one side 120 of the adhesive layer 118. A cover strip 122 is attached to an opposed side 124 of the adhesive layer 118 to be removed prior to use. In use, a base member of a filing accessory (not shown) having a pair of flexible elongate elements arranged on, and extending from, the base member, is adhered to the side 124 of the adhesive layer 118 once the cover strip has been removed. The fastener 112 is positioned relative to the prongs 14 so that an engaging member arranged on a free end of each elongate element is releasably engageable with an end of each filing prong 14 to retain the elongate elements in a configuration in which transfer of sheets from the filing prongs on to the elongate elements is facilitated. The folder 110 is supplied separately from the accessory. It follows that storage space can be efficiently utilised due to the fact that only the prongs 14 and the fastener 112 are in the folder 110. It will be appreciated that the folder 110, when used with the accessory, will be transformed into a file which can be used in a similar manner as a ring or arch-type binder. Thus, the pages can be transferred from the back cover 55 to the front cover 59 and vice-versa, book-fashion. Furthermore, removal of sheets from the folder 110 (for example, to copy or to telefax) and subsequent re-insertion, while retaining the original sequence of the sheets, is facilitated. The Applicant believes that the invention provides a filing arrangement which combines the filing advantages of a file such as a file having a ring or arch-type mechanism together with the space-saving advantages and low cost of a flat manilla or kraft-type folder. One of the reasons for this is that, when the arms 20 are bent to engage their associated prongs, they define a self-supporting arch along which sheers can be transferred smoothly. This self-supporting arch arises since the base 18 is fixed to the inner surface 57 of the front cover 59. Smooth transfer is further facilitated by the manner in which the components 26 engage the ends of the prongs 14. Once a desired position in a stack of sheets is found, a user simply pulls the components 26 off their respective prongs 14 and removes and/or adds sheets. The fact that the sheets are always either on the prongs 14 or the arms 20, effectively removes the problems associated with alignment of sheets prior to replacing the sheets on the prongs 14. When not in use, the arms 20 can be pivoted into their second position. The dimensions of the arms 20 are such that, when in the second position, the thickness of the folder is determined largely by the thickness of the stack of sheets. It will be appreciated, therefore, that the invention provides a significant advantage with regard to utilisation of storage space, over a standard ring or arch-type mechanism file and the like. The cost of manufacturing the arrangement 10 will be substantially less than the present cost of manufacturing a ring or arch-type mechanism file. Since such files are often not used to their full capacity, excessive cost and inefficient space utilisation result. Thus, the cost of manufacturing the arrangement 10 and the space saving features explained above are particularly advantageous. The fact that the base 18 is secured to the front cover 59 also imparts stability to the arms 20 during transfer of sheets. Control and ease of transfer of sheets as well as retrieval or addition of sheets is facilitated. Where the bridge 24 and the arms 20 are detachable from the base 18, the bridge 24 and the arms 20 can be used with a number of different folders, each supplied with the base 18.
