Definitions

  • This invention relates to a device for looseleaf binding of papers and documents.
  • a secondary object of this invention is to provide flexibility of use by permitting the binding of covers as well as pages, so that the covers and not the binding means relate to the content of the assembled document, allowing the use of one looseleaf binding means for a range of documents.
  • Looseleaf binding devices are shown in US-A-3057357 and US-A-3183913.
  • Several embodiments of device are shown in US-A-3057357 but all are either complex integral mouldings or are assembled from separate components utilizing ball-and-socket type joints.
  • the ball-and-socket embodiments avoid the problems of the relatively complex tooling necessary to produce the moulded embodiments, the ball-and-socket arrangements are not well adapted to resisting shock loading as would occur if a sheaf of bound documents is dropped. Under such loading conditions the ball will tend to pop out of the corresponding socket with the resultant failure of the device.
  • the device of US-A-3183913 requires, in addition to two separate spine members, a base member which holds the spine members and controls movement thereof. This additional component adds to the cost and weight of the device. Also, the device illustrated is liable to snap over-centre into its release configuration in the event of shock loading of the type referred to above.
  • the present invention provides a looseleaf binding device of the type referred to in the pre-characterising portion of claim 1 which is characterised in that the interengaging components comprise a plurality of tongue-like projections formed integrally with one of the elongate members and a plurality of apertures defined by the other of the elongate members for receiving the tongue-like projections to secure the elongate members together.
  • the tongue-like projections are each connected to the remainder of the elongate member with which they are formed by means of hinge portions, the hinge portions of the tongue-like projections cooperating to form a hinge which permits articulation of the spine members relative to each other.
  • the tongue-like projections each have a tapered lead-in region and a barb so that the tongue-like projections may readily be inserted into the corresponding apertures until the barbs snap behind the means defining the aperture. With this arrangement, the device may readily be assembled but is highly resistant to accidental disassembly.
  • the locking member may comprise a strip slidable between the first and second extensions to hold the device in the closed configuration, but in a particularly preferred embodiment the locking member comprises a strip pivotably attached to one of the first and second extensions along one longitudinal edge of the strip, the strip being pivotable between a first, free position and a second locking position in which the strip engages with the other of the first and second extensions to hold the device in the closed configuration.
  • the locking member is formed integrally with one of the elongate plastics members forming the spine or, in an alternative embodiment, integrally with the remainder of the device.
  • the strip is provided with a tab for ease of movement between its first and second positions.
  • a recess may be provided on the other of the first and second extensions such that the strip may be positively located in the locking position.
  • the width of the locking member is such that when it is in its use position it somewhat elastically deforms one or both of the extensions and/or the first and/or second finger members so that the free ends of the finger members engage each other with a slight pre-load.
  • the effect of this arrangement is to resist separation of the fingers and, and the same time, resist displacement of the locking strip from its use position.
  • the spine is intended to be suitably sized to contain common sizes and volumes of looseleaf pages, and the number of finger means may be selected to form two or more closed loops as appropriate, depending on the number of holes provided in the pages.
  • the shape and cross-section of the finger means may also be selected as appropriate for any particular application of the device.
  • the binding device comprises a spine 2 which may be manufactured from a semi-flexible plastics material for example polypropylene.
  • the spine 2 incorporates a longitudinal hinge 3 which may be formed by locally narrowing the thickness of the plastics material of the spine.
  • a number of fingers 4 and 4a extend from the spine, on either side of the hinge 3, the fingers being integrally formed with the spine and being suitably sized and spaced to accept pre-punched pages 5, as shown in Figure 2.
  • the device 1 is hingeable between a first, open position, illustrated in Figure 1, in which pre-punched pages 5 can be impaled over fingers 4a, for example, and a second, closed position illustrated in Figure 2, in which the free ends of the fingers 4 and 4a on either side of the hinge are brought together to hold the pages 5 on the closed loops formed by the cooperating fingers 4 and 4a.
  • the free ends 6 of the fingers 4 and 4a may be formed with suitably shaped mating portions to provide positive cooperation between the fingers in the closed position.
  • Two short extensions 7 and 7a are formed one on either side of the hinge 3 in spine 2.
  • the extensions 7 and 7a project rearwardly from the spine, and the inside faces of these extensions are provided with grooves, formed to locate a locking member 8 which may be made of a thin strip of rigid material having a length similar to the spine.
  • the locking member 11 is hingeable connected by a hinge 12 to the extension 7a.
  • the locking member and hinge are formed integrally with the extension 7a.
  • this locking member is in the position shown in broken line when the device is open.
  • the locking member 11 can be pivoted in the direction of arrow 13 to snap into a recess on the interior face of extension 7 to hold the device in the closed position.
  • the Figure 4 embodiment shows a spine which is constructed in two parts 14a and 14b held together by means of the hinge 15.
  • Part 14b is formed with an enlarged edge 16 providing one part of the hinge
  • part 14a is formed with a socket 17 along its edge, the socket 17 being adapted to fit around the enlarged edge 16 to provide the cooperating part of the hinge 15.
  • the locking member 18 is formed integrally with extension 7 but in alternative arrangements the locking member may be formed integrally with extension 7a, or may provided as a separate slidably located locking strip.
  • the locking member 18 is joined to extension 7 by a hinge 19 and is in a position similar to that shown in broken lines when the device is open.
  • the locking member 18 When the device is closed, as shown in Figure 4, the locking member 18 can be pivoted in the direction of arrow 20 to lock between extensions 7 and 7a, and to clip into a recess on the interior face of extension 7a to positively locate the locking strip when the device is closed.
  • one or more tabs 21 may be formed on the locking strip 6 so as to protrude from the outside face of extension 7a via one or more suitable slots provided in the extension 7a.
  • the binding device is formed by two separate plastics mouldings 22, 23.
  • Moulding 22 comprises extension 7, spine portion 14a and fingers 4.
  • Moulding 23 comprises extension 7a, spine portion 14b, fingers 4a and locking member 18.
  • Spine portion 14a has, integrally formed therewith, a plurality of tongue-like projections 24 each of which is connected by an integral hinge 25 to the spine portion 14a.
  • An aperture corresponding to each tongue-like projection 24 is formed to one side of the spine portion 14b by a generally U-shaped bar 26 moulded integrally with the spine portion 14b.
  • Each tongue-like projection 24 has a tapered lead-in region and a barb (as best seen in Figure 6) so that the tongue-like projections 24 may readily be inserted into the corresponding apertures until the barbs on the tongue-like projections snap under the bars 26. Thereafter, removal of the tongue-like projections from apertures will be very difficult.
  • the locking member 18 of the embodiment of Figure 5 is formed in a manner similar to that of the embodiment of Figure 4, and operates in the same manner as that described above with reference to Figure 4.
  • the device In the open position of the locking member, as shown in solid line in Figure 6, the device may be opened.
  • the closed position of the locking member As shown in broken line, the edge of the locking member snaps into a groove 27 provided in the extension 7a to lock the device closed.
  • hinging movement of the two portions of the device is accomplished by the hinged portions 25.
  • the axial shape of the fingers 4 and 4a may be substantially semi-circular to form a circular loop when the device is closed, or the closed loop may be substantially square or rectangular, or may have any other suitable shape.
  • the cross-section of the individual fingers 4 and 4a may be circular to suit generally available paper punching means, or may be rectangular, or any other suitable shape.
  • the locking member should be removed (in the case of a separately formed strip) or released (in the case of an integral strip), and the fingers 4 and 4a of the binder opened by pressing together the extensions 7 and 7a formed on each side of the hinge at the rear of the spine.
  • Pages formed with suitably sized and positioned holes can be impaled over the fingers.
  • the binding device can be closed using pressure on the outer surfaces of the fingers.
  • the binding device is positively locked in the closed position by inserting or positioning the locking member between the two extensions 7 and 7a formed at the rear of the spine so that the strip firmly bridges the gap across the hinge line and places the fingers under a slight preload. Pages are released by again removing or releasing the locking strip and opening the fingers.
