CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of copending U.S. application Ser. No. 11/490,687, filed Jul. 21, 2006, which is incorporated herein by reference.


This application is related to U.S. application Ser. No. 11/522,626, filed Sep. 18, 2006 and U.S. application Ser. No. 11/681,636, filed Mar. 2, 2007, both of which are incorporated herein by reference.
BACKGROUND
Media binders are used for holding a wide variety of items, including sheets of physical media, such as loose sheets of paper and the like. A media binder typically includes a cover and a binding mechanism for retaining physical media sheets that are inserted in the media binder. Many different binding mechanisms have been used to secure physical media sheets in such media binders. For example, some media binders include a metal channel that is crimped onto the physical media sheets in order to apply a mechanical holding force that retains the physical media sheets within the media binders. Some other media binders include an adhesive, such as a thermally activatable adhesive or a pressure sensitive adhesive, which bonds the physical media sheets within the binders. In some media binders, a front cover and a back cover are attached to opposite sides of one or more spring clamps that are located in the spine of the binder; the front and back covers can be folded back against the sides of the spring clamps, whereby the front and back covers act as levers and the spine acts as a fulcrum in opening the spring clamps to enable items to be inserted between the clamping surfaces of the spring clamps.
It oftentimes is difficult to achieve aesthetically pleasing binding results with the media binders that currently are available. For example, such media binders typically either require the user to position and register the physical media sheets without any guidance before securing the sheets to the media binder or they require a separate bulky alignment apparatus for positioning and registering the sheets within the media binder. As a result, such media binders typically either do not allow the user to achieve aesthetically pleasing binding results or they require the user to use a cumbersome alignment apparatus. Therefore, what are needed are media binders that provide aesthetically pleasing binding results with an intuitive and easy-to-use binding process.

DETAILED DESCRIPTION
In the following description, like reference numbers are used to identify like elements. Furthermore, the drawings are intended to illustrate major features of exemplary embodiments in a diagrammatic manner. The drawings are not intended to depict every feature of actual embodiments nor relative dimensions of the depicted elements, and are not drawn to scale.
I. Introduction
The embodiments that are described herein provide media binders that provide aesthetically pleasing binding results with an intuitive and easy-to-use binding process. These embodiments include a datum stop that provides a datum stop surface against which a collection of physical media sheets is registerable prior binding the collection within the media binder. The datum stop allows users to position and register the physical media sheet collection prior to binding without requiring a separate cumbersome alignment apparatus. In this way, these embodiments enable users to easily achieve aesthetically pleasing binding results.
II. Overview
FIG. 1 shows a perspective view of a collection 10 of physical media sheets (e.g., sheets of paper and the like) and an exploded view of an embodiment of a media binder 12 for holding the collection 10 of physical media sheets.
The physical media sheet collection 10 is characterized by a front face 14, a back face 16, a spine end 18, a head end 20, a tail end 22, and a fore-edge end 24.
The media binder includes a cover 26, a binding system 28, and a datum stop 30.
The cover 26 includes an inwardly facing side 32 an outwardly facing side 34. The cover 26 also includes a front part 36, a spine part 38, and a back part 40. Each of the front, spine, and back parts 36-40 of the cover 26 typically is formed of multiple material layers, including an outer covering layer and discrete front, spine, and back base layers. The outer covering layer typically is formed of a durable material (e.g., a textile). The central region of the outer covering is attached to the outwardly facing surfaces of the front, spine, and back base layers, whereas the marginal edges of the outer covering layer typically are folded over the side edges of the base layers and attached to the inwardly facing surfaces of the front, spine, and back base layers. The front, spine, and back base layers typically are formed of a rigid planar material (e.g., paperboard or a stiff polymeric material). In some embodiments, the spine base layer is segmented into multiple sections to facilitate bending during opening and closing of the media binder 12. In other embodiments, the cover 26 is formed of one or more layers of flexible material (e.g., plastic).
In some embodiments, the front part 36 of the cover 26 includes an optional window that allows users to see an image on the first front facing one of the physical media sheets of the collection 10 after it is loaded into the media binder 12. Some embodiments include an optional protective sheet that is affixed to the front base layer. In general, the protective sheet may be formed of a wide variety of different materials, including an acetate material, a single or composite polymeric film, or vellum. The protective sheet typically is made of a transparent material in embodiments in which the window is present. A decorative front pastedown sheet typically is attached to the inwardly facing surface of the front base layer over the frontside marginal edges of the outer covering layer and over a folded down edge of the protective sheet (if present). A decorative back pastedown sheet also typically is attached to the inwardly facing surface of the back base layer over the backside marginal edges of the outer covering layer.
The binding system 28 is attached to the inwardly facing side 32 of the cover 26. The binding system 28 is operable to bind the collection 10 of physical media sheets to the cover 26. The binding system 28 may be implemented in a wide variety of different ways, including but not limited to all the ways described in detail below an in U.S. application Ser. No. 11/490,687, filed Jul. 21, 2006, U.S. application Ser. No. 11/522,626, filed Sep. 18, 2006, and U.S. application Ser. No. 11/681,636, filed Mar. 2, 2007. The binding system 28 typically includes at least one component that extends in a spinal direction 41 along the inwardly facing side of the spine part 38 of the cover 26.
The datum stop 30 protrudes away from the inwardly facing side 32 of the cover 26 and includes a datum stop surface 42 against which the collection 10 of physical media sheets is registerable prior to binding the collection 10 to the cover 26. The datum stop 30 typically protrudes in a direction orthogonal to the spinal direction 41. The datum stop surface 42 typically is orthogonal to the inwardly facing side 32 of the cover 26. The datum stop 30 typically is disposed at a distal end of the spine part 38 of the cover 26. The datum stop surface 42 provides an edge against which the head end 20 or the tail end 22 of the collection 10 of physical media sheets may be registered to achieve an aesthetically pleasing binding of the physical media sheets with aligned edges. In some embodiments, a second datum stop is provided at the opposite end of the spine part 38 of the cover 26. The datum stop 30 typically is formed of a rigid material (e.g., a rigid plastic or metal material). In some embodiments, the datum stop 30 is attached to the media binder 12 by a breakable link that allows the user to detach the datum stop 30 from the media binder after the collection 10 of physical medial sheets have been secured to the cover 26.
In some embodiments the datum stop 30 protrudes from a component of the binding system 28. In these embodiments, the datum stop 30 may be a separate and discrete component that is attached to the binding system 28 using, for example, an adhesive or a mechanical attachment mechanism; alternatively, the datum stop 30 may be part of a component of the binding system 28—for example, the datum stop 30 and the binding system component may be integral components of a single stamped metal part or a single molded plastic part. In other embodiments, the datum stop 30 protrudes from a region of the spine part 38 of the cover 26 adjacent the binding system 28.
In other embodiments, the datum stop 30 is an integral component of a datum bar that includes a spacer that extends in the spinal direction 41 along the spine part 38 of the cover 26. The spacer typically has a planar datum surface against which the spine end 18 of the collection 10 of physical media sheets may be registered so that the fore-edge end 24 of the sheets present a clean edge to the user. The datum surface of the spacer also sets the height of the physical media sheet collection 10 above the spine part 38 of the cover 26. In this way, the spacer datum surface limits the insertion depth of physical media sheets into the spine of the media binder and, thereby, reduces the marginal portions of the physical media sheets that otherwise might be obscured by the sheet retention mechanism of the binding system 28. In this regard, the spacer has a thickness that positions the spacer datum surface a desired height above the spine part 38 of the cover 26. In some embodiments, the spacer has tapered side walls as described in U.S. application Ser. No. 11/681,636, filed Mar. 2, 2007.
In some embodiments, the cover 26, the binding system 28, and the datum stop 30 are sold preassembled into the media binder 12. In other embodiments, the cover 26, the binding system 28, and the datum stop 30 are sold as a kit in which one or more of these components must be combined with the other components to form the media binder 12.
III. Exemplary Media Binder System Embodiments
A. Media Binder Systems that Include Trough-Based Cover Binding Systems
Some embodiments of the media binder 12 have cover binding systems that include a trough for receiving the spine end 18 of the collection 10 of physical media sheets and providing a support structure that shapes the spine of the media binder 12.
1. Binding Systems Having Mechanical Sheet Retention Systems
FIG. 2 shows an embodiment 50 of the binding system 28 that includes an elongated body 52. The elongated body 52 includes a front side wall 54, a back side wall 56, and a spinal side wall 58 whose inner surfaces collectively define a trough 60. The elongated body 52 also includes an embodiment 62 of the datum stop 30. In the illustrated embodiment, the elongated body 52 and the datum stop 62 are formed of a single piece of an inelastically deformable material (e.g., a stamped metal piece).
FIG. 3 shows an embodiment 70 of the binding system 28 that includes an elongated body 72. The elongated body 72 includes a front side wall 74, a back side wall 76, and a spinal side wall 78 whose inner surfaces collectively define a trough 80. The binding system 70 also includes a datum bar 82 that includes an embodiment 84 of the datum stop 30 and a spacer 86. The datum stop 84 and the spacer 86 typically are formed of a single piece of material (e.g., metal or plastic). In the illustrated embodiment, the elongated body 72 is formed of a single piece of an inelastically deformable material (e.g., a stamped piece of metal, such as steel). The datum bar 82 and the elongated body 72 are attached to one another using, for example, an adhesive or a mechanical attachment mechanism.
FIG. 4A shows an embodiment 90 of the media binder 12 that includes a binding system 92 of the type shown in FIGS. 2 and 3 that includes an elongated body 94, which is formed of an inelastically deformable material, and a datum stop 95. The binding system 92 is attached to the inwardly facing side of the spine part 38 of the cover 26 using, for example, an adhesive or a mechanical attachment mechanism. The media binder 90 additionally includes a front pastedown sheet 96 and a back pastedown sheet 98, which extend over the trough defined by the elongated body 94 before the collection 10 of physical media sheets is registered against the datum stop 95 and inserted into the trough.
FIG. 4B shows the media binder 90 after terminal sides 100, 102 of the elongated body 94 have been crimped onto outer faces of the collection 10 of physical media sheets. A separate tool (e.g., a binding apparatus of the type described in any of U.S. Pat. Nos. 4,986,713, 5,314,283, and 5,330,229) typically is used to crimp the terminal sides 100, 102 of the elongated body 94. The gripping force that is applied by the terminal sides 100, 102 of the elongated body 94 typically is sufficient to retain the collection 10 of physical media sheets under normal operating conditions.
2. Binding Systems Having Adhesive-Based Sheet Retention Systems
a. Binding Systems Having Adhesive in a Central Area of the Spine Part of the Cover
FIG. 5 shows an embodiment 104 of the binding system 28 that includes an elongated body 106 that defines a trough 108 containing a pressure sensitive adhesive 110 with an overlying backing 112. The elongated body 106 includes a front side wall 114, a back side wall 116, and a spinal side wall 118 whose inner surfaces collectively define the trough 108. The binding system 104 also includes an embodiment 120 of the datum stop 30. In the illustrated embodiment, the elongated body 106 and the datum stop 120 are formed of a single piece of an inelastically deformable material (e.g., a stamped metal piece). In other embodiments, the datum stop 120 is part of a datum bar of the type shown in FIG. 3, in which the datum stop 120 is formed integrally with a spacer from a single piece of material (e.g., metal or plastic). In the illustrated embodiment, the elongated body 106 is formed of a single piece of a rigid material (e.g., a plastic material or a stamped piece of metal, such as aluminum or stainless steel).
In the illustrated embodiment, pressure sensitive adhesive 110 with the overlying backing 112 is affixed to the inner surface of the spinal side wall of the elongated body 106. In other embodiments, pressure sensitive adhesive with overlying backing may be affixed to the inner surfaces of the front and back side walls 114, 116 of the elongated body instead of or in addition to the pressure sensitive adhesive 110 on the spinal side wall 118. As used herein, a “pressure sensitive adhesive” refers to a class of adhesive compositions that are applied with pressure and generally do not undergo a liquid to solid transition in order to hold materials together. Pressure sensitive adhesives may be solvent-free natural or synthetic resins characterized by the rapid wetting of a surface to form an adhesive bond upon contact with the surface under pressure. The backing overlying the pressure sensitive adhesive typically is formed of paper with a non-stick top surface opposite the surface in contact with the pressure sensitive adhesive.
FIG. 6A shows an embodiment 122 of the media binder 12 that includes the binding system 104 shown in FIG. 5. The binding system 104 is attached to the inwardly facing side of the spine part 38 of the cover 26 using, for example, an adhesive or a mechanical attachment mechanism. FIG. 6B shows the media binder 104 as the backing 112 overlying the pressure sensitive adhesive 110 is being removed by a user. FIG. 6C shows the media binder 104 after the backing 112 has been removed and after the collection 10 of physical media sheets has been registered against the datum stop 120 and bound to the cover 26 by the pressure sensitive adhesive 110.
b. Binding Systems Having Adhesive in Adhesive Areas of the Front and Back Parts of the Cover
FIG. 7A shows an embodiment 124 of the collection 10 of physical media sheets being loaded into an embodiment 126 of the media binder 12.
The collection 124 includes front and back end sheets 128, 130. In the illustrated embodiment, each of the front and back end sheets 128, 130 is a physical media sheet (e.g., a paper sheet) that includes a plasticized layer 132, 134 and a tear-line (indicated diagrammatically by the dashed lines 136, 138) that extends in a direction parallel to the spinal direction. In some embodiments, the tear-lines 136, 138 are implemented by tearable perforation lines. In the illustrated embodiment, the collection 124 of physical media sheets, including the end sheets 128, 130, is bound into a book block before it is loaded into the media binder 126. The collection 124 may be bound in a wide variety of different ways, including but not limited to attaching an adhesive binding strip to the spine end 18 of the collection 124 and binding the collection with a mechanical attachment mechanism, such as one or more staples (indicated diagrammatically by the dashed line 139).
The media binder 126 includes pressure sensitive adhesive 140, 142 on front and back adhesive areas 144, 146 of the inwardly facing front and back parts 36, 40 of the cover 26. The tear-lines 136, 138 of the end sheets 128, 130 are spaced from the spine edges of the end sheets 128, 130 by a distance that is at least as far as the distance separating the outer edges 148, 150 of the front and back adhesive areas 144, 146. The media binder 126 also incorporates an embodiment 152 of the binding system 28 of the type shown in FIGS. 2 and 3, which includes an elongated body 154 that defines a trough, and a datum stop 156. In this embodiment, the elongated body 154 and the datum stop 156 may be formed of any type of rigid material, including but not limited to metal and plastic. In addition, the elongated body 154 and the datum stop 156 may be integral parts of a single material piece or they may be discrete parts that are mechanically or adhesively attached to one another.
FIG. 7B shows the media binder 126 after the bound collection 124 of physical media sheets has been registered against the datum stop 156 and then attached to the cover 26 by the pressure sensitive adhesive 140, 142. As shown in FIG. 7B, after the collection 124 is secured to the cover 26, the fore-edge portions of the end sheets 128, 130 may be removed by tearing the ends sheets 128, 130 along the tear-lines 136, 138.
c. Binding Systems Having Adhesive in Side Areas of the Spine Part of the Cover
FIG. 8 shows an embodiment 160 of the media binder 10 in an open state. FIG. 9A shows an enlarged view of a central region 162 of the media binder 160.

The front and back parts 170, 174 of the cover 164 respectively include front and back base layers 176, 178. The front base layer 176 includes a window 179 that allows users to see an image on the first front facing one of the physical media sheets of the collection 10 after it is loaded into the media binder 160. The front and back base layers 176, 178 are attached to an outer covering 180, which is formed of a durable material (e.g., a textile). The central region of the outer covering 180 is attached to the outwardly facing surfaces of the front and back base layers 176, 178; the marginal edges of the outer covering 180 are folded over the side edges of the front and back base layers 176, 178 and attached to the inwardly facing surfaces of the front and back base layers 176, 178. The front and back base layers 176, 178 typically are formed of a rigid planar material (e.g., paperboard or a stiff polymeric material).
In the illustrated embodiment, a binding system 182 is attached to the outer covering 180 in the spine part 172 of the cover 164. The binding system 182 includes an elongated body 183 that has a front side wall 184, a spinal side wall 186, and a back side wall 188 that together define a trough for receiving the collection 10 of physical media sheets. Pressure sensitive adhesive 190, 192 is located on the front side wall 184 and the back side wall 188. The pressure sensitive adhesive 190, 192 is capable of binding front and back faces of the collection 10 of physical media sheets to the elongated body 183. The pressure sensitive adhesive 190, 192 typically is covered by an overlying backing before the collection 10 is loaded into the media binder 160. In some embodiments, the pressure sensitive adhesive is applied to only one of the front side wall 184 and the back side wall 188. The binding system 182 additionally includes a datum stop 194. In this embodiment, the elongated body 183 and the datum stop 194 may be formed of any type of rigid material, including but not limited to metal and plastic. In addition, the elongated body 183 and the datum stop 194 may be integral parts of a single material piece or they may be discrete parts that are mechanically or adhesively attached to one another.
Referring to FIGS. 9A and 9B, the front and back side walls 184, 188 of the elongated body 182 are bendable with respect to the spinal side wall 186 between the open state shown in FIG. 9A, in which the elongated body 182 presents an enlarged opening for receiving the collection 10 of physical media sheets, and the closed state shown in FIG. 9B, in which the elongated body 182 defines the trough around the spine end 18 of the collection 10. In the process of binding the collection 10 of physical media sheets, a user registers the collection against the datum stop 194 and the spinal side wall 186. After removing the backing overlying the pressure sensitive adhesive 190, 192, the user bends the front and back side walls 184, 186 along lines of preferential bending between the spinal side wall 186 and each of the front and back side walls 184, 188 until the pressure sensitive adhesive 190, 192 contacts the front and back faces 14, 16 of the collection. The lines of preferential bending may be implemented by an indentation, a crease, or score line that facilitates bending of the elongated body 182 along the parallel intersections between the spinal side wall 186 and each of the front and back side walls 184, 188.
FIG. 10 shows an embodiment 200 of the media binder 10 in an open state. FIG. 11A shows an enlarged view of a central region 202 of the media binder 200. The media binder 200 includes a cover 204 that has an inwardly facing side 206 an outwardly facing side 208. The cover 200 also includes a front part 210, a spine part 212, and a back part 214. The front and back parts 210, 214 of the cover 204 respectively include front and back base layers 216, 218. The front base layer 216 includes a window 219 that allows users to see an image on the first front facing one of the physical media sheets of the collection 10 after it is loaded into the media binder 200. The front and back base layers 216, 218 are attached to an outer covering 220, which is formed of a durable material (e.g., a textile). The central region of the outer covering 220 is attached to the outwardly facing surfaces of the front and back base layers 216, 218; the marginal edges of the outer covering 220 are folded over the side edges of the front and back base layers 216, 218 and attached to the inwardly facing surfaces of the front and back base layers 216, 218. The front and back base layers 216, 218 typically are formed of a rigid planar material (e.g., paperboard or a stiff polymeric material).
In the illustrated embodiment, a binding system 222 is attached to the outer covering 220 in the spine part 212 of the cover 204. The binding system 222 includes an elongated body 224 that includes a front piece 226 and a back piece 228, which are bendable about a hinge 230. The front piece 226 includes a front side wall 232, a front tail-end datum stop 234, and a front head-end datum stop 236. The back piece 228 includes a spinal side wall 238, a back side wall 240, a back tail-end datum stop 242, and a back head-end datum stop 244. The tail-end datum stops 234, 242 provide datum surfaces for registering the tail end 22 of the physical media sheet collection 10 and the head-end datum stops 236, 244 provide datum surfaces for registering the head end 20 of the physical media sheet collection 10. In this embodiment, the elongated body 224 and the datum stops 234, 236, 242, 244 may be formed of any type of rigid material, including but not limited to metal and plastic. In addition, the elongated body 224 and the datum stops 234, 236, 242, 244 may be integral parts of a single material piece or they may be discrete parts that are mechanically or adhesively attached to one another.
