This application claims the benefit at least in part of the filing date of pending U.S. patent application Ser. No. 14/171,778, for METHOD AND DEVICE FOR PROVIDING ATTACHMENT POINTS FOR A FOLDER, filed Feb. 4, 2014, the entire disclosure of both of which is hereby incorporated by reference.
The present invention relates to the field of folders such as pocket folders that may be used to store documents or other items and that may be mounted into ringed binders, and more specifically to a device used to maintain secure attachment points of a folder within a ringed binder.
In the past, folders such as pocket folders had holes punched into standard locations with which to attach or mounts the folders into a binder. The locations of the holes on the folder corresponded to standard locations of releasable rings on binder. A folder was mounted to the binder by releasing the binder rings (which could be any appropriate shape such as circular or D-shaped), feeding the holes into the corresponding binder rings, and closing the binder rings. Folders with holes as mounting points typically have a high rate of failure, especially folders made from paper, because pressure on the holes from the rings of the binder causes the material between the holes and the edge of the folder to tear.
A folder with torn attachment points cannot be attached into a three ringed binder and therefore must be repaired or replaced. Available repair devices that are used for lighter weight paper products are not suitable to handle folder repair because the loading capacity against the attachment points are too great to achieve sustained use.
Accordingly, it is desirable to provide a method and apparatus to apply reinforced attachment points to a folder so that it may be securely mounted into a ringed binder.
An improvement in folder design is disclosed in which an attachment device provides primary attachment, reinforcement, or repair of a folder at points which the folder would normally be mounted onto a ringed binder. By utilizing a plurality of this device (typically three) one may extend the useful life of a folder, reduce waste created by replacing damaged folders, and reduce the cost of ownership of folders that experience frequent handling.
In one embodiment, the attachment device has a supporting segment, which may be embedded in an adhesive sheet of material or sandwiched between adhesive sheets of material that may press against the closing mechanism to contain the folder in the binder.
The attachment device may have a layer of material with an inside surface and an outside surface. The layer of material may have a main fold line for folding the inside surface of the layer of material onto itself along the main fold line to form a doubled layer having a folded edge. The layer of material may have a first hole and a second hole arranged such that, when the inside surface of the layer of material is folded onto itself along the main fold line, the first hole is superimposed over the second hole and the superimposed holes define a cut out section in the folded material.
The attachment device may also have a supporting segment extending along at least a portion of the inside surface of the layer of material and passing across the first hole to close the cut out section into an aperture in the folded material when the inside surface of the layer of material is folded onto itself. The aperture in the doubled layer is arranged to receive a closing mechanism of a binder. In certain embodiments, the first hole in the layer of material extends to the second hole such that, when the inside surface of the layer of material is folded onto itself along the main fold line, the cut out section extends to and causes a break in the folded edge. The supporting segment may extend across the first hole at the folded edge of the attachment device.
The attachment device may also have a retaining sheet applied to at least a portion of the inside surface of the layer of material over the supporting segment to embed the supporting segment into the attachment device.
In certain embodiments, the supporting segment is arranged to extend along at least the portion of the inside surface of the layer of material at the main fold line. The supporting segment may be made of metal, plastic, string, cord, mono-filament or other suitable material. It may be of any suitable cross-section (such as circular, oval, or flat). It may be multi- or single stranded, and it may have sufficient rigidity, when the folder is mounted in the binder and the binder's closing mechanism is pressed against the supporting segment, to prevent reliance or minimize reliance on adhesive bond between the attachment device and the folder for holding the supporting segment in place across the folder openings.
In certain embodiments, adhesive may be applied to the outside surface of the layer of material to cause the outside surface to adhere to an inside surface of the folder. The adhesive may be pressure sensitive or it may be any other suitable kind of adhesive. In still further embodiments, a backing sheet may cover and protect the adhesive on the outside surface of the layer of material. The backing sheet may have a release coating on its surface for easy removal of the backing sheet when the outside surface of the attachment device is being adhered to the inside surface of the folder.
In other embodiments, a method is provided for providing attachment points for a folder for use in a binder using an attachment device that has an aperture defined by a hole in the attachment device and a supporting segment extending across the hole along or parallel to at least a portion of an edge of the attachment device. The attachment device may be attached to a folder with an outside surface, an inside surface folded over itself at a folder fold line, and folder openings in both sides of the folded folder near the folder fold line. The folder openings are arranged to superimpose over each other on the folded folder and are further arranged to receive a closing mechanism of the binder.
In the method, the attachment device may be sandwiched within the folded folder, with the attachment device aperture being sandwiched between the folder openings, and with the supporting segment being positioned at or near the folder fold line between the folder fold line and a far edge of the sandwiched attachment aperture and folder openings. The attachment device may be attached to the folded inside surface of the folder with the edge of the attachment device at or near the folder fold line. The edge of the attachment device may be formed by folding the attachment device onto itself along a main fold line on the attachment device. Both sides of the folded folder may be arranged to press against the attachment device to contain the attachment device in the folder, and the supporting segment may be arranged to press against the closing mechanism to contain the folder in the binder.
In further embodiments, the attachment device may be attached to the folded inside surface of the folder by removing a first portion of a backing sheet on an outside surface of the attachment device to expose a first portion of adhesive on the outside surface of the attachment device; and positioning the attachment device so that the main fold line of the attachment device extends along the folder fold line. The first portion of exposed adhesive may be pressed to the folder. A second portion of a backing sheet on the outside surface of the attachment device may be removed to expose a second portion of adhesive on the outside surface of the attachment device. An inside surface of the attachment device may be folded on to itself along the main fold line of the attachment device to form the edge of the attachment device; and the second portion of exposed adhesive may be pressed to the folder.
In other embodiments, a method is provided for attaching a folder into a binder using an attachment device. The attachment device has an aperture that is defined by a hole in the attachment device and a supporting segment extending across the hole along or parallel to at least a portion of an edge of the attachment device. The attachment device may be sandwiched within a folded folder, with the folder having an outside surface, an inside surface folded over itself at a folder fold line, and folder openings in both sides of the folded folder near the folder fold line. The folder openings are arranged to superimpose over each other on the folded folder, and are further arranged to receive a closing mechanism of the binder.
In the method, the attachment device aperture is sandwiched between the folder openings, and the supporting segment is positioned at or near the folder fold line between the folder fold line and a far edge of the sandwiched attachment aperture and folder openings. Further, the attachment device is attached to the folded inside surface of the folder with the edge of the attachment device at the folder fold line; and the closing mechanism of the binder is fed through the attachment device aperture. Both sides of the folded folder are arranged to press against the attachment device to contain the attachment device in the folder, and the supporting segment is arranged to press against the closing mechanism to contain the folder in the binder.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one (several) embodiment(s) of the invention and together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to the present exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same or similar reference numbers will be used throughout the drawings to refer to the same or like parts.
The supporting segment 103 may be located along the main fold line 109. In one embodiment, when the embedded supporting segment 103 formed of a wire, the supporting segment 103 is located one half of the wire's diameter away from the main fold line 109. Further, in one embodiment, the supporting segment may extend the entire length of the attachment device 100. In other embodiments the supporting segment 103 may extend across a portion of the length of the attachment device 100. The supporting segment 103 location may bisect the slotted opening 105 in the direction of narrowest dimension. In other embodiments, the supporting segment 103 may extend across the slotted opening parallel to and near the main fold line 109. The supporting segment 103 may be made formed of metal, plastic, string, cord, mono-filament or other suitable material. For example, it may be a metal wire. It may be of any suitable cross-section (such as circular, oval, or flat). It may be multi- or single stranded, and—it may have sufficient rigidity, when the folder is mounted in the binder and the binder's closing mechanism is pressed against the supporting segment, to prevent reliance or minimize reliance on adhesive bond between the attachment device and the folder for holding the supporting segment in place across the folder openings. The supporting segment is secured to the base tape layer 102 by fastening two portions of an upper tape layer 104a, 104b which are bonded to the base tape layer 102 and supporting segment 103 by an adhesive layer 205b so as to embed the supporting segment 103 into the attachment device 100.

Before applying the device to a folder 400, the intended attachment points may be modified to facilitate mounting of the attachment device. For example, the area surrounding the intended attachment point of the sheet may be modified to remove sheet material that may obstruct the slotted feature of the device. Alternatively, as shown in

The attachment device 100 with a portion of its adhesive layer 203 exposed may be positioned on the folder 400 with the edge 309 of the attachment device 100 at or near the folder fold line 409 so that the main fold line 109 of the attachment device extends along the folder fold line 409, so that the attachment device aperture 305b is sandwiched between the folder openings 405a, 405b, and so that the supporting segment 103 is positioned at or near the folder fold line 409 between the folder fold line 409 and a far edge of the sandwiched attachment aperture 305b and folder openings 405a, 405b.
Once the device 100 is positioned at the appropriate attachment point, the first portion of exposed adhesive 203 may be pressed to the folder 400. The device may then be folded around the main fold line 109 to form the edge 309 of the device 100 along the length of the embedded supporting segment 103. In one embodiment, the folding places the embedded support segment 103 at the edge 309 and in the same plane as the attachment device 100. It is not generally required that the embedded supporting segment 103 be aligned exactly to the edge 309 in order for the device 100 to function properly to provide or reinforce the attachment points of the folder 400.
A second portion of a backing sheet 206 on the outside surface 107b of the attachment device 100 may be removed to expose a second portion of adhesive 203 on the outside surface 107b of the attachment device. An inside surface 107a of the attachment device 100 may be folded to itself along the main fold line 109 of the attachment device to form the edge 309 of the attachment device; and the second portion of exposed adhesive 203 may be pressed to the folder 400. The attachment device 100 is thus secured to both sides of the main fold line of the folder.
Multiple attachment devices 100 may be employed to produce secure attachment points to a folder. The application points may be standard locations that would normally be used to attach a folder to each closing mechanism of a multiple ring binder. The application process is repeated for every attachment point of the folder. As may be viewed in

The various layers of the attachment device 800 include the base layer 802; adhesive layer 803 (which may have the adhesive characteristics and properties of layer 203); and paper backing substrate layer 806 with silicon release coating 807. The supporting segment 813 is sandwiched between the base layer 802 and the base silicon release coating 807, either directly touching the base layer 802 or resting on the adhesive layer 803.
The supporting segment 813 is located along a center fold line and may extend the entire length of the device or only partially across the length of the device 800. The supporting segment 813 bisects a curved slotted opening in the direction of narrowest dimension. The supporting segment 813 is bonded to the base layer 802 by the pressure sensitive adhesive 803 and is covered by the substrate and silicon release layers until the time of application. As with the supporting segment 103 of attachment device 100, the supporting segment 813 may have sufficient rigidity, when the folder is mounted in the binder and the binder's closing mechanism is pressed against the supporting segment, to prevent reliance or minimize reliance on adhesive bond between the attachment device and the folder for holding the supporting segment in place across the folder openings. Application of attachment device 800 to the folder 400 may be performed in the manner described for attachment device 100.
In operation, as with attachment device 100, when the folded folder 400 is mounted into the binder as in
Thus, it can be seen that the devices described will reinforce folder attachment points when inserted into a ringed binder. The devices may be used on a folder where the attachment points have been previously damaged and cannot be retained in a ringed binder. Alternatively, the devices may be used during folder manufacturing as an alternative method for providing attachment points when used in a ringed binder. The devices may be used on a modified folder as a replacement for previous methods of retainment in a ringed binder, and may provide a strong attachment point to a folder as an alternative to existing methods. The described attachment device increases the useful life of a folder because the attachment points are strengthened by the supporting segment which is embedded within the attachment.
One skilled in the art will appreciate that although only one or two of the components identified above is depicted in the Figures, any number of any of these components may be provided. Furthermore, one of ordinary skill in the art will recognize that there may be more than one supporting segment, and that functions provided by one or more components of any of the disclosed systems may be combined or incorporated into another component shown in the Figures.
As one of ordinary skill in the art will appreciate, one or more of units may be optional and may be omitted from implementations in certain embodiments. For example, in order to reduce cost, the user or a manufacturer may choose to reinforce only a portion of a folder's reinforcement points. Thus, giving a folder at least some strong attachment points may be sufficient to retain the folder in the binder and to restrict the folder from turning out of the binder during normal use. Further, for folders having only a portion of its attachments points damaged, in order to reduce cost the user may also apply the device to a portion of the undamaged attachment points in order to provide additional strength to the folder. This insures that a pocket folder would not fall out of the binder if the other un-reinforced attachment points of the folder fail. Thus, the attachment devices described herein may provide additional strength to attachment points of a folder even when only a few of the folder's attachment points are reinforced or repaired.
The foregoing description has been presented for purposes of illustration. It is not exhaustive and does not limit the invention to the precise forms or embodiments disclosed. Modifications and adaptations of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed embodiments. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
