DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to the binding of pages into a binder. In particular, the present invention relates to the use of magnets to hold pages together, for example, in a binder or cover. (As used herein, the terms "magnet", "magnetizable material", and "magnetic material" are given their common meanings, which are understood to be as follows. "Magnet" means a body that provides a magnetic field; a body that possess the property of attracting magnetic materials. "Magnetizable material" means a material that can be magnetized (by the magnetic field from another magnet) thereby to become a magnet--for example, iron. "Magnetic material" means a material that is attracted to a magnet, but that does not itself provide a magnetic field.)
As representative of the present invention, FIGS. 1-3 illustrate an apparatus in the form of a binder assembly 10 constructed in accordance with a first embodiment of the invention. The binder assembly 10 is used for displaying sheets of display material 12. The binder assembly 10 includes a binder 20, and a plurality of page assemblies 40 mounted in the binder.
The binder 20 (FIGS. 1-3) includes a cover 22 and a base member 24. The cover 22 is shown as being a one-piece plastic construction including a front cover 26, a back cover 28, and a spine 30 located between the front cover and the back cover. The cover 22 could be made from other materials, and could have a different construction and/or configuration than those shown and described herein.
The cover 22 is scored at 32 between the front cover 26 and the spine 30, and at 34 between the spine 30 and the back cover 20, to provide for predetermined areas of hinging (bending) for opening the cover. An additional score line 36 is provided in the back cover 28, near the spine 30.
The base member 24 is located on a portion 38 of the back cover 28, near the spine 30, between the score lines 34 and 36. The base member 24 extends for substantially the full height of the cover 22, from top to bottom. The base member 24 is a member that is attracted to a magnet. The base member 24 therefore could be a member made of a magnetic material, or could be another magnet. The base member is secured to the cover 22 in a manner described below. It should be understood that the present invention is applicable also to binders that do not include a base member--that is, binder assemblies that include page assemblies magnetically attracted to each other but not to the cover.
FIG. 4 illustrates one type of page assembly 40 that is usable in the present invention. Alternative types of page assemblies are described below. The page assembly 40 includes a magnet portion 42, a hinge portion 44, and a display portion 46.
The page assembly 40 is preferably formed as single unitary one piece. More preferably, the page assembly 40 is formed from a moldable plastic material 48 that has the following characteristics: flexibility, strength to hold the display material 12 over repeated flexings, cost efficiency, and design aesthetics. One suitable material for the page assembly is extruded or molded vinyl.
The magnet portion 42 of the page assembly 40 has a generally rectangular cross-sectional configuration, as can be seen in FIG. 4. The magnet portion 42 has a bar-shaped or strip-shaped configuration extending the length (from top to bottom as viewed in FIG. 1) of the page assembly 40.
The magnet portion 42 has parallel, flat upper and lower major side surfaces 43 and 45, and parallel, flat inner and outer minor side surfaces 47 and 49. The length and width of the magnet portion 42 are similar to the length and width of the base member 24 of the binder 20. In one embodiment, the magnet portion 42 has a dimension of about one-half inch in width, and about one-sixty-fourth inch in thickness. The magnet portion 42 could be wider or narrower, and could be thicker or thinner. The magnet portion 42 is preferably as thin as possible while still providing the needed magnetic strength.
The magnet portion 42 of the page assembly 40 includes a magnet 52 embedded in the plastic body material 48 of the magnet portion 42. The magnet 52 as shown in FIG. 4 is a plurality of magnetic pieces, or particles. The magnet 52 may, as shown in FIG. 5, alternatively be a single magnetic piece, such as a strip magnet. Such a magnet may be purchased from McMaster-Carr company, online at mcmaster.com, "flexible magnetic stripping". The magnet 52, whether in powder form or in solid form, is preferably embedded during the process of forming of the plastic body 48 by molding, for example, by injection molding.
The hinge portion 44 of the page assembly 40 in the illustrated embodiment is formed as a sheet or tab that extends outward from the outer side surface 49 of the magnet portion 42. The hinge portion 44 (FIG. 44) has parallel upper and lower major side surfaces 56 and 58, and in the illustrated embodiment is thinner than the magnet portion 42. Preferably they are the same thickness.
The hinge portion 44 preferably includes a predetermined weakened portion 60 for encouraging hinging of the page assembly 40 at a predetermined location. In the illustrated embodiment, the predetermined weakened portion 60 is formed by a score line that is spaced apart from the magnet portion 42. The width of the hinge portion 44 and the spacing of the score line 60 are selected so that the page assemblies 40 can lie flat or substantially flat on either the front cover 26 or the back cover 28, as described below. The hinge portion could include a predetermined weakened portion formed in another manner. A hinge portion made from fabric would not need a predetermined weakened portion.
The display portion 46 of the page assembly 40 is formed as an outwardly extending (away from the magnet portion 42) continuation of the hinge portion 44 of the page assembly. The display portion 46 is designed to support the display material 12. This can be done in different ways. One embodiment is illustrated in FIG. 4. Other types of display portions may be provided.
In the embodiment illustrated in FIG. 4, the display portion 46 includes two spaced apart layers 64 and 66 that together define a pocket 68 for receiving the display material 12--like a sheet protector. The pocket 68 (FIG. 2) has an open top edge 70, a bottom edge 72, and an outer side edge 74. The pocket 68 may be, for example, sized to accommodate an 8.5.times.11 inch display item, or could be substantially larger, for example up to 16.times.20 inches or more. The display material 12 could be a photograph, for example.
The magnet portion 42 of the page assembly 40 is designed so that the magnetic field provided by the magnet 52 is strong enough to hold the page assembly 40 in position on the binder 20. Specifically, the magnetic field provided by the magnet 52 is strong enough to attract the base member 24 and thereby releasably attach (magnetically) the page assembly 40 to the binder 20. When the magnet portion 42 of the page assembly 40 is placed on or in a position overlying the base member 24, as shown in FIG. 6, the magnet 52 of the page assembly 40 attracts the base member 24. The magnetic attraction is strong enough to clamp, or releasably attach, the magnet portion 42 to the base member 24. As a result, the entire page assembly 40 is releasably attached to the binder 20. The page assembly 40 may be removed from the binder 20 by separating the magnet portion 42 of the page assembly from the binder cover 22, breaking the magnetic attraction that holds the pieces together.
As noted above, the binder 20 is designed to hold or mount a plurality of page assemblies 40 in the binder. Such an arrangement is shown in FIGS. 1-3 and 6. In these drawings, there are shown the binder 20 and the page assembly 40. There are also shown three additional page assemblies 40a, 40b and 40c that are identical or similar to the page assembly 40. The page assemblies 40a-40c are mounted in the binder 20 with their magnet portions 42a-42c disposed in a stacked relationship on the magnet portion 42 of the page assembly 40 and thereby over the base member 24. The magnet portions 42a-42c of the three page assemblies 40a-40c, and the magnet portion 42 of the page assembly 40, all magnetically attract each other and hold the four page assemblies 40, 40a, 40b and 40c together as a group. The magnetic attraction between the magnet portion 42 of the one page assembly 40 and the base member 24, holds the stack of four page assemblies 40-40c in the binder 20. As a result, all four page assemblies 40-40c are releasably attached, or removably maintained, in the binder 20.
When the binder assembly 10 is opened to view some of the display materials 12 in the page assemblies 40, the front cover 26 is laid open (to the left as viewed in FIG. 3). The cover 22 bends at the score line 32 between the front cover 26 and the spine 30 to allow the front cover to lie open or flat on the underlying support surface 70. The cover 22 also bends at the score line 34 between the spine 30 and the back cover 26. In addition, the cover 22 bends at the score line in the back cover 36. The score line 36 is preferably underneath the hinge portions 44-44c of the page assemblies 44. Together these features enable the spine 30 to lift off the support surface 70 between the spine and the back cover 26. The stack of magnet portions 42 tips up off the surface 70. This enables the back cover 28 to lie substantially horizontal for good viewing. The width of the magnet portions 42-42c, the location of the score lines 60-60c, and the locations of the score lines 33, 34 and 36 are all selected together to enable this to occur.
When the page assemblies 40-40c are in the binder 20, they may be flipped or pivoted between front and back to enable viewing of individual page assemblies. As this occurs, the page assemblies 40-40c bend at their hinge portions 44-44c. The magnet portions 42-42c themselves do not flip over, but instead stay in position stacked on the back cover 26.
In one alternative construction, the binder 20 can be made partially or completely from a magnetic material, such as metal. In this case, a separate base member 24 may be unnecessary.
The base member 24 can be mounted to the cover 20 in various ways. In the embodiment shown in FIGS. 1-7, and discussed above, the base member 24 is a magnet or metal strip that is glued or otherwise adhered to the cover 20. The base member 24 may be embedded in (molded with or bonded into) the cover 20, as shown, or surface mounted. In the embodiment shown in FIG. 8, the base member 24 is a metal strip (or magnet) that is riveted or otherwise secured to the cover 20 with fasteners 72, such as rivets.
As noted above, alternative types of page assemblies are usable in the present invention. The alternative types of page assemblies may have a different construction for the magnet portion, for the hinge portion, and/or for the display portion.
One alternative type of page assembly 80 is shown in FIG. 9. The page assembly 80 may be used when it is desired that the display material 12 be open (exposed) on both sides, rather than received in a pocket as with the page assembly 40 (FIG. 4).
This page assembly 80 includes a hinge portion 82, or hinge, that is made from a strong, flexible sheet material, such as the material 48 of the page assembly 40. On a first section 84 of the hinge 82 there is mounted a magnet 86. The magnet 86 may be similar in construction to the strip magnet 52 discussed above with reference to FIG. 5. The magnet 86 is adhered by glue or adhesive 88 to the first section 84 of the hinge 82, rather than being embedded as in FIG. 5.
The hinge 82 has a predetermined weakened portion in the form of a score line 90 for guiding the hinge to bend at that location. On the opposite side of the score line 90 from the magnet 86 is a display portion 92 of the hinge 82. The display portion 92 is a width of the material of the hinge 82 that is wide enough to support the display material 12.
The hinge 82 includes an adhesive 94 that may be covered by a release paper 96. Removal of the release paper 96 enables display material 12 to be adhesively secured to the hinge 82 by movement in a direction as indicated by the arrows 98. This page assembly 80 has the advantage of being small in dimension, easily attached to display material 12, and open in the area of the display material. The hinge 82 could have adhesive on both sides, as an alternative.
Another alternative type of page assembly 100 is shown partially in FIG. 10. In this page assembly 100, the magnet portion includes a magnet 102 that is self-adhered as by molding of the material of the hinge member 106 to a section 104 of the hinge member.
FIG. 11 shows a magnet portion 42e that can be used with any of the page assemblies of the present invention, especially those with an exposed magnet. In the magnet portion 42e (FIG. 11), a magnet 52e is located on one side of the sheet material 110 of the hinge 112. A metal strip 114 made of a magnetic material is located on the other side, with the sheet material 110 of the hinge 112 sandwiched between them. The metal strip 114 serves to provide a more decorative appearance to the one side of the magnet portion 42e of the page assembly. In addition, the metal strip 114 provides a magnetic material to which a magnet portion of an adjacent page assembly can be attracted. Because the metal strip 114 is a magnetic material rather than a magnet itself, it does not have strong poles. Therefore, a magnet portion of an adjacent page assembly can, in some cases, be aligned more precisely with the metal strip 114, as compared to alignment with another magnet.
A binder assembly in accordance with the present invention may optionally include a device to help hold the magnet portions of the page assembly to the binder. As one example, FIG. 12 is a section through the binder assembly 10, taken through the magnet portions 42 in a direction looking toward the spine 30. The top of the binder assembly 10 is to the right as viewed in FIG. 12, and the bottom of the binder assembly is to the left as viewed in FIG. 12.
The binder assembly 10 includes a clip 120. The clip 120 in the illustrated embodiment is a plastic member having a width approximately the same as that of the magnet portions 42, but could be made from metal. The clip 120 has a generally C-shaped configuration as seen in FIG. 12. The clip 120 includes a first end portion 122, a second end portion 124, and a central portion 126 that extends between and interconnects the first and second end portions.
The back cover 26 includes two slots 128 and 130 adjacent the ends of the stack of magnet portions 42. The first end portion 122 of the clip 120 extends through the slot 128 in the back cover 28. A first terminal end portion 132 of the clip 120 clamps against the back cover 28, at a location between the two slots 128 and 130.
The second end portion 124 of the clip 120 is a mirror image of the first end portion 122. The second end portion 124 extends through the other slot 130 in the back cover 28. A second terminal end portion 134 of the clip 120 clamps against the back cover 28, at a location between the two slots 128 and 130.
The clip 120 is made from a resilient material that enables it to be bent along its central portion 126 so that the end portions 122 and 124 may be lifted into the slots 128 and 130. When the clip 120 is installed as shown in FIG. 12, it applies a clamping force (upward and downward as viewed in FIG. 12) that tends to hold the magnet portions 42 of the page assemblies 40 tight against the back cover 28.
FIG. 13 illustrates an alternative clip design. The clip 140 is mounted in a manner not shown on the back cover 142 of a binder 144. The clip 140 has a C-shaped configuration as viewed in cross-section in FIG. 13, including a base 146 and two legs 148 and 150. The clip is preferably made from a resilient material, such as spring steel, so that the legs 148 and 150 clamp on a plurality of page assemblies 40.
FIGS. 14 and 15 illustrate a binder assembly 152 that is a further embodiment of the invention, which includes additional lateral positioning support for page assemblies. Specifically, the binder assembly 152 includes a binder 154 and a plurality of page assemblies 156. The page assemblies 156 are similar to those shown above at 40, with the exception that each one additionally has a slot 158 through its magnet portion 42.
The binder 154 includes a bar 162 that projects upward from the back cover, over the base member 164. The page assemblies 156 fit over the bar 162 which extends through the slots 158. The bar 162 limits movement of the page assemblies 156 relative to the binder 160. This is exemplary of the concept of providing additional lateral positioning support for the page assemblies.
Another example of providing additional lateral positioning support for the page assemblies is shown in FIG. 16. FIG. 16 shows a binder assembly 170 that is similar to the one shown in FIG. 1. Additionally, the binder assembly 170 of FIG. 16 includes a post binding system 172 of a known type. Each one of the magnet portions 42 of the page assemblies 40 has one or more openings for receiving an equal number of posts 176 of a known configuration. The posts 176 limit movement of the page assemblies 40 relative to the cover, thereby providing additional lateral positioning support for the page assemblies.
FIG. 17 illustrates a stack of page assemblies 40 that is usable without a separate binder. Each one of the page assemblies 40 includes a magnet portion 42, a hinge portion 44, and a display portion 46. The upper and lower page assemblies 180 and 182 may be thicker, as shown, to serve as covers. As a result, a binder may not be needed, as the stack of page assemblies 40 forms a functional unit on its own.
From the above description of the invention, those skilled in the art will perceive improvements, changes and modifications in the invention. Such improvements, changes and modifications within the skill of the art are intended to be covered by the appended claims.
