Description
0 LOCKING MECHANISM FOR A FOLDER/BINDER Field of the Invention.
The present invention relates to stationery and in particular to binders or folders for containing papers or other documents.
Background Art.
00 Various ring binders are known in the art which have a paper sheet Cfl retaining device attached to a cover member by a plurality of fasteners, such as rivets, o which extend through the cover member and which are deformed, for example, by punching, to securely and permanently fix the paper retaining device to the cover member.
Ring binders are generally folders into which documents are easily inserted and removed from, and which may be stored in erect position in a row of folders when individual folders are vertically positioned in horizontally extending rows.
Document or file folders, manila folders, are well known and are employed for collecting, accumulating, and indexing or segregating a plurality of related documents in a unitary volume. Typical applications for document folders include bundling and indexing legal documents and retail sales records. In retail specialty sales, sales receipts are kept as a record of business transactions for each day for financial reasons and as a record of a customer's instructions concerning an order Many document folders employ paper board stock which is so flexible that the folder does not have sufficient stiffniess to stand vertically without lateral support. In addition to this, many ring binders and similar folders are designed such that the free edges of the folder may be forced together and are retained apart only by the thickness of the documents contained in the folder. This can result in damage to other items contained in the folder if the folders are stacked as the folder covers are forced together.
It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowl[edge in the art in Australia or in any other country.
Summary of the Invention.
The present invention is directed to a locking mechanism for a folder/binder, which may at least partially overcome at least one of the o abovementioned disadvantages or provide the consumer with a useful or commercial choice.
In one form, the invention resides in a locking mechanism for a folderibinder, the folder/binder having front cover, a rear cover and a spine portion, 00 the locking mechanism including a first portion associated with the front cover having at least one tab member and at least one opening and a second o portion associated with the rear cover having at least one tab member and at least one In opening associated therewith, the tab member of the first portion engaging the opening of the second portion and the tab member of the second portion engaging the opening of the first portion to lock the front cover of the folder/binder relative to the rear cover of the folder/binder.
Normally the locking mechanism of the present invention will be used with a document folder or binder used to contain loose papers or the like. The locking mechanism is suitably operable between a closed and an open or free condition when the folder/binder is in the closed condition.
The folder/binder can be manufactured of a variety of materials such but plastic will generally be used for its strength, relatively light weight and easy of manufacture. The preferred plastic may be transparent, partially or substantially opaque or coloured to suit the preference or desires of the user.
Typically, the folder/binder will be at least semi-rigid in order to maintain its shape, particularly when stood on one edge of the front cover, the spine portion and the rear cover as folders generally are stored. The semi-rigid nature of the folder/binder may also help to protect the contents of the folder/binder.
The three portions of what can be considered as the folder binder body portion, namely the front cover, the spine portion and the rear cover, will preferably be separated by fold or hinge lines allowing each of the portions to be folded or rotated about each other portion to which it is attached. The fold or hinge lines will typically be weak enough to allow the folding of the portions but will be strong or durable enough to resist breaking due to the repeated opening and/or closing of the folder/binder.
3 0 The folder/binder will normally be provided with a ring binder mechanism. A typical ring binder mechanism functions to secure half-rings arranged in a row upon carrier rails, which are surrounded by a housing of a spring elastic material. The catrer rails are so introduced into the housing that they can assume two rest positions, one open and one closed. The housing functions as a spring element, 00 which retains the half-rings in their open position or in their closed position.
The ring binder mechanism may be provided with a number of rings, o typically three or four spaced evenly over the height of the folder/binder.
The folder/binder will normally have a front cover. The front cover will normally be a substantially planar sheet member and will generally have dimensions slightly larger that the contents which it is designed to contain. Typically, the folder/binder will be provided in different configurations and sizes to allow for containing different sizes of materials.
There may be a plurality of ring engaging means provided on the front cover to each engage with a ring on the ring binder mechanism. Generally, each ring engaging means will take the form of an opening defined by an edge and a protrusion into the opening so that when the front cover is folded to the closed condition, the opening will align with a ring and the ring will be received at least partially in the opening. The protrusion may then engage with the part of the ring received in the opening to hold the part of the ring in the opening thereby holding the front cover in the closed condition until sufficient force is applied to dislodge the ring from the protrusion, The folder/binder will normally have a rear cover. The rear cover will normally be a substantially planar sheet member and will generally have dimensions slightly larger that the contents which it is designed to contain. Typically, the folder/binder will be -provided in different configurations and sizes to allow for containing different sizes of materials. Typically, the front and rear covers will be equal in size.
The ring binder mechanism discussed above will generally be provided on the rear cover portion adjacent the spine portion. The rings of the ring binder mechanism will generally be oriented to align with the openings of the ring engaging means provided on the front cover.

O
0 The spine portion of the folder/binder will generally link the front cover and the rear cover of the folder binder relative to one another and will generally be separated from each of the front and rear covers by a fold or hinge line. The spine -portion will normally be a planar sheet member, the height of the spine portion being equal to the height of the front and rear covers. The width of the spine portion will 0 normally govern the width of the folder/binder and typically the amount of materia that can be contained in the folder/binder.
oThe spine. portion will preferably be provided with one or more openings to facilitate gripping or moving the folder/binder. The spine portion may also be provided with labelling areas or arrangements to allow the folder/binder to be labelled for identification purposes.
The locking mechanism includes a first portion associated with the front cover having at least one tab member and at least one opening and a second portion associated with the rear cover having at least one tab member and at least one opening. The locking mechanism will typically be used when the folder/binder is in the closed condition (when the front cover is closed). During operation of the locking mechanism, the tab member of the first portion engages the opening of the second portion, and the tab portion of the second portion engages the opening of the first portion to lock the front cover of the folder/binder relative to the rear cover of the folder/binder.
Further, the inter-engagement of the respective tab members and openings preferably results in the locking mechanism providing a substantially rigid edge to the folder/binder on the edge opposed to the spine portion of the folder/binder, making the folder/binder box-like in configuration.
The first portion of the locking mechanism is associated with the front cover and has at least one tab member and at least one opening.
The first portion of the locking mechanism will suitably include a flap portion. Typically, the flap portion will extend over substantially the entire height of the folder/binder. The flap portion will preferably be of equal dimension to the spine portion in both height and width. By providing a flap portion of substantially similar dimensions to the spine portion, when the flap portion is folded into a locking position approximately perpendicular to the front cover, the closed and locked folder/binder 0 may assume a box-like configuration. The flap portion will typically be separated from the front cover by a fold or hinge line.
Typically, the flap portion may have a free edge on the edge opposite the fold or hinge line. Also provided on the free edge may be the at least one tab member. The at least one tab member may be provided as a tongue-like protrusion 00 from the free edge of the flap portion. A tongue-like protrusion will typically be provided approximately centrally along the edge of the flap portion, A single, o centrally located tab portion may be provided or more than one may be provided. If only a single tab member is provided, then it is preferred that the tab be approximately centrally located but it need not be. Preferably any tab members provided on the flap portion may extend from the flap portion in the same plane as the flap portion.
The flap portion is also provided with at least one opening therein.
Preferably, an opening may be provided for each tab member provided on the second portion of the locking mechanism. Each opening will typically extend substantially parallel to the fold or hinge line between the flap portion and the front cover.
Generally each opening will be spaced from the hinge or fold line. Each opening will typically be an elongate slot with the smaller dimension of the slot being slightly greater than the thickness of the tab member to be received therein.
The second portion of the locking mechanism is associated with the rear cover and has at least one tab member and at least one opening.
The second portion of the locking mechanism will suitably also include a flap portion. Typically, the flap portion will not extend over the entire height of the folder/binder, but instead be segmental in shape. The flap portion will preferably be of equal dimension to the spine portion in width but will typically only extend part of the height of the folder/binder. The flap portion will typically be separated from the rear cover by a fold or hinge line.
Typically, the flap portion may have a arcuate free edge on the edge opposite the fold or hinge line.
The at least one tab member may be provided on the flap portion and spaced from the free edge of the flap portion. Typically, a single tab member will be provided approximately centrally on the flap portion. The tab member will generally be formed from a substantially C-shaped incision in the flap member and providing a fold or hinge line between the tab member and the flap portion. Preferably, the fold or 6 ohinge line will be provided adjacent to but spaced from the free edge of the flap portion and the C-shaped incision will extend toward the fold or hinge line between the flap portion and the rear cover. The hinge or fold line of the tab member will typically be spaced from the free edge of the flap portion by a distance similar to the spacing between the opening on the first portion and the front cover.
00 A single, centrally located tab member may be provided or more than one may be provided. If only a single tab member is provided, then it is preferred that o the tab be approximately centrally located but it need not be. Preferably any tab In members provided on the flap portion may be foldable about the fold or hinge line to extend from the flap portion in a plane which is different to that of the flap portion.
Preferably, the tab member may extend in a direction opposed to the direction at which the flap member extends from the rear cover.
The flap portion is also provided with at least one opening associated therewith. Preferably the opening may be in or through the flap portion.
Alternatively, the opening may be provided in or through the rear cover adjacent the fold or hinge line between the flap portion and the rear cover. Preferably, an opening may be provided for each tab member provided on the first portion of the locking mechanism. Each opening will typically extend substantially parallel to the fold or hinge line between the flap portion and the rear cover. Generally the opening will not be spaced from the hinge or fold line, and instead, each opening may be positioned at the fold or hinge line. Each opening will typically be an elongate slot with the smaller dimension of the slot being slightly greater than the thickness of the tab member to be received therein.
The locking mechanism may be moveable between an open and a temporarily locked condition. When in the locked condition, the tab of the first portion is generally inserted into the opening associated with the second portion to form a substantially box-like folder/binder. The tab portion of the second portion is then suitably folded about the hinge or fold line to enter the opening in the first portion to temporarily lock the first and second portions relative to one another.
Suitably, the flap portions are positioned to be one inside the other prior to the locking mechanism being operated to the locked condition.
Preferably, the tab member of the front cover prevents the flap portion from folding towards or away from the spine portion of the folder/binder and the tab 7
