Patent Application
20170326904
The present invention relates to moveable and interconnectable substrates that allow users to mark thereon or display items therein and, more specifically, to erasable writing tablets with interconnection features.
Dry erase boards are known and typically include a board or substrate that is coated with an enamel, film, ultraviolet cured liquid, liquid varnish, or porcelain finish. Specially designed markers are used to write on the substrate. While the ink of the marker dries on the substrate, the ink does not bond to the substrate surface and the writing can be easily removed with a soft eraser, cloth, finger, etc.
However, improved rewritability performance of other articles with writing surfaces is desired. A persistent challenge with such articles which has not yet been satisfactorily met is that the writing surfaces do not accept writing from a variety of writing instruments, do not erase cleanly and easily, and tend to degrade when ink is erased. A continuing need exists to provide such articles with rewritable surfaces thereon that exhibit improved rewritability.
Other disadvantages of traditional dry erase boards are the inability to easily move writing on the board to another location on the board and the inability to easily apply graphics to or change graphics on the substrate. For example, some dry erase boards are provided with horizontal lines for writing purposes. However a user may not want lines on the board at all times.
Additionally, the use of erasable boards for presentations is generally known. Such boards include chalkboards, such as blackboards and greenboards, and whiteboards. For ease in presenting and storing data, individuals have come to rely on several boards instead of just one board fastened to a wall.
The prior art has presented several options for a user of erasable boards. In U.S. Pat. No. 3,531,898 to Facemire, which is incorporated by reference herein in its entirety, a plurality of display boards is suspended for sliding along a track. In U.S. Pat. No. 3,914,890 to Behlen, Jr., which is incorporated by reference herein in its entirety, a plurality of display panels or signs are mountable within tracks formed in parallel upstanding side posts. In U.S. Pat. No. 4,716,693 to Webster, which is incorporated by reference herein in its entirety, the structure includes details of roller assemblies used for movably supporting a sign or panel along a track. In U.S. Pat. No. 6,139,331 to Owen, which is incorporated by reference herein in its entirety, a board base apparatus provided both storage and display of board panels using slots or tracks.
Each of these prior art storage and display units includes tracks in order to store the erasable boards. However, inserting and removing the boards from the units can be difficult because each board must fit into a narrow track in order to properly hold the board. Additionally, the removable boards can only be used when tracks are present. Thus, the erasable boards are not transportable to locations without the tracks. Further, these units are difficult to work with and are expensive.
In many facilities, providing writing and demonstration tools in the walls of existing rooms may not be feasible due to cost or structural constraints. Thus in order to provide such tools, free-standing whiteboards may be used. These tools may take up space and/or be cumbersome to use and then store.
These and other needs are addressed by the various embodiments and configurations of the present invention. This invention relates to a novel system, device, and method for providing tablets with interconnection and/or mounting features. Embodiments of the present invention relate to a system of multiple tablets and a system for displaying the multiple tablets. More particularly, embodiments of the present invention relate to an erasable writing tablet system that provides for the easy interconnection of the tablets, the quick rearrangement of the tablets without the use of slots or tracks, the easy interchangeability of writing surfaces and designs thereon, and an innovative wall mounting system.
Features of the present invention may be employed in a wide range of uses, including the presentation of analog and digital material. Although the invention generally relates to writing tablets, such as dry erase boards, with interconnection features, the invention and features described herein could easily be implemented on chalk boards, electronic writing tablets, picture frames, clocks, artwork, signs, and other presentation media. The term “tablet” may be used interchangeable with the term “board” herein.
It is thus one aspect of various embodiments of the present invention to provide a system of tablets, such as erasable writing tablets, which can be interconnected with, disconnected from, and rearranged with respect to one another. A user may write on one board, write on another board, and then interconnect the two boards together using the boards' interconnection means. The interconnection means may be magnets, hooks, hook and loop material, straps, clips, buckles, hinges (such as a barrel hinge, living hinge, single continuous hinge, or piano hinge), female and male locking catches, or any interconnection mechanism known in the art. Further, the tablets may be assembled in any configuration on a vertical plane (e.g., wall surface) or a horizontal plane (e.g., table surface).
It is another aspect of embodiments of the present invention to provide a system of tablets that can be interconnected to one another back-to-back and/or side-by-side on either a horizontal surface or a vertical surface. A further aspect includes providing a system of tablets and mounting mechanisms that allow multiple tablets to be interconnected to a vertical wall such that one tablet can be removed from the wall and/or moved to a new position on the wall without removing or moving the other tablets. Thus, if the system includes nine tablets in a square arrangement, the center tablet must be removable and reattachable without removing or moving the other eight tablets.
One aspect of embodiments of the present invention is to provide a tablet system that allows a user to easily and quickly reorganize the tablets with respect to one another such that the user may move around the tablets as he sees fit. Thus, if one aspect or one section of the entire board or presentation makes more sense in a different location, then the user may easily move only the one or more tablets with that section/aspect to a different location relative to the other tablets.
Another aspect of embodiments of the present invention is to promote collaboration among groups by allowing multiple people to contribute small ideas or small parts of a big idea and combine those small ideas into one big idea. Thus, each person may write or draw his/her small part on an individual tablet and then all of the tablets can be combined and arranged to form one big idea or one big picture.
It is another aspect of some embodiments of the present invention to provide a system of tablets that may be easily mounted on a wall and the tablets may be interconnected to one another on the wall. Thus, the tablets may be positioned on a wall or taken off of the wall individually to allow a user to write on one or more of the tablets. Additionally, the tablets may be rearranged on the wall with respect to one another.
In still another aspect of the embodiments of the present invention, a system of erasable writing tablets is provided where the writing tablets are releasably adhered to a wall. Accordingly, the tablets are positioned substantially parallel to the wall, if the wall is flat.
It is one aspect of the embodiments of the present invention to provide tablets that, when interconnected, are properly aligned. Thus, the interconnection means provided on the tablets allow for accurate alignment of the tablets. Additionally, the mounting brackets can have mechanisms to ensure the proper alignment of the mounting brackets.
Another aspect of various embodiments of the present invention is to provide a mounting system, which may be a plurality of mounting assemblies, that is aesthetically pleasing when it is not covered by tablets. Thus, the mounting assemblies can form a design when they are interconnected together. Additionally, one mounting assembly is also aesthetically pleasing when it is mounted alone. Further, the mounting assemblies can be different colors or have different designs on their upper or front surfaces.
One aspect of embodiments of the present invention is to provide a plurality of mounting assemblies, which can interconnect to a plurality of tablets, that is easy to install, can be installed almost anywhere, and is easily movable to different locations.
It is a further aspect of embodiments of the present invention to provide an infinitely expanding system of mounting assemblies and tablets. Accordingly, one mounting assembly can be secured to a surface to interconnect with one tablet, or multiple mounting assemblies can be secured to a surface to interconnect with multiple tablets. Further, the system may start with a few mounting assemblies and tablets and at a later time, more mounting assemblies and tablets can be added to the system.
It is one aspect of embodiments to provide a mounting assembly system comprising a plurality of mounting assemblies that can interconnect to different items. Thus, for example, artwork, clocks, cork boards, pictures, photographs, calendars, white boards, chalkboards, games, signs, and the like, can be hung or fixed to the mounting assemblies. Additionally, multiple tablets or items can interconnect to multiple mounting assemblies or one large item (e.g., a large piece of art) can interconnect to multiple mounting assemblies.
Another aspect of embodiments of the present invention is to provide a tablet with interconnection means to fasten or hold together two tablets back-to-back such that materials and objects can be contained between the two interconnected tablets. Thus, one aspect of embodiments of the present invention is to provide erasable writing tablets with locking mechanisms to secure two or more tablets together for travel. The locking mechanisms may secure multiple tablets together, either back-to-back or stacked one on top of another. The locking mechanism allows the user to unlock the locking mechanism and separate the tablets for presentation and/or use.
It is another aspect of embodiments to provide a tablet with a frame and a tray (i.e., cover, top portion, upper portion, or overmold) that are easily interconnected and detachable from one another such that various trays can be used or various inserts can be inserted between the tray and frame. Thus, different colored frames can be used with an at least partially transparent tray such that the frame can be seen through the tray. Alternatively, frames with different upper surfaces (e.g., different texture, writing surface, design, transparency, etc.) or different designs, such as lines, graphs, charts, calendars, plain, etc.) can be used with the base. Further, the removable tray allows different inserts, such as paper with different designs such as lines, graph paper, tables, clocks, calendars, etc., to be used with the base. The inserts can be seen through the tray as long as the tray is at least partially transparent.
In one embodiment of the present invention, the tablets are dry-erase boards (also known as “markerboards,” “whiteboards,” or “dry-wipe boards”) with a smooth, glossy surface on one side (for example, the upper side) of the board. The upper surface of the tablet can either be clear or colored, for example, white, so a user can mark or write on the board's upper surface. If the upper surface is clear, then either the frame or the insert can be white or another solid color so a user can mark or write on the board's upper surface. Whiteboards operate analogously to chalkboards in that they allow markings to temporarily adhere to the surface of the board. These markings are removed more easily on whiteboards than chalkboards. Dry-erase boards have become rather common in most work environments, classrooms, and the like, due to their less messy and easily erasable writing surfaces. However, unlike a chalkboard, and the need for chalk to make markings on the board, the dry-erase board uses easily erasable markers to make marks on the board. The use of an erasable, non-permanent marker allows the user to make frequent changes and alterations to the written form without the hassle of chalky residue normally accompanying chalkboards. Dry-erase boards may be constructed with a plurality of different materials, but are typically made of porcelain enameled steel which provides greater durability, but is typically heavy and difficult to move.
A standing challenge for dry-erase articles is to find surfaces that can be easily cleaned, resist staining when written on with permanent markers, can be easily erased when written on with conventional dry-erase markers, and are durable. Dry-erase writing that is not removable by a dry eraser is commonly called ghosting. Different surfaces provide different amounts of ghosting. Thus, some embodiments of the present invention include glass, graphene, or porcelain surfaces for the tablet's upper surface, (i.e., the writing surface) because these surfaces are non-porous so they are easily written on with dry-erase markers and then easily erased after a short time. In other embodiments, the tablet's upper surface is a polymer, such as acrylic, abrasion resistant acrylic, or polycarbonate.
According to one embodiment of the present invention, the writing surface of the tablet may include a magnetic re-writable surface or a flexible magnetic dry-erase surface. Thus, the magnetic writing surface could be a large magnet that attaches to and detaches from the tablet base such that users could remove the magnetic writing surface to write on it, then reattach it to the board for presentation purposes.
One embodiment of the present invention includes one writing tablet with a calendar displayed on the re-writable surface. In another embodiment, one writing tablet has a blank writing surface, a grid, or any other preferred writing surface.
Some embodiments of the present invention include a clear window and a panel coupled to the window to define an opening between the clear window and the panel for inserting a document thereto via one side of the clear window. Alternatively, the tablet may have a clear, detachable tray that fits over a frame such that documents and designs can be inserted between the tray and the frame.
In one embodiment of the present invention, the tablet includes a metal reinforced hole for hanging the tablet on a hook or string. The tablet can have other mounting mechanisms to mount or hang the tablet. Some embodiments of the present invention also include handles that can be removably interconnected to any or all of the tablets. The handle can also clampingly secure a wall mounting bracket to the tablet, thereby permitting secure fixation of the tablet on a wall.
Further embodiments of the present invention include a utensil pocket coupled to the back or underside of the tablet. The pocket may be secured to the back of the tablet or may be releasably interconnected to the back of the tablet. Alternatively, the back of the tablet can include two or more straps for storing other items on the underside of the tablet. In some embodiments, the tablet includes spaces or channels to engage clips of various shapes. The shape of the clip will determine what accessories and materials the clips can hold on an underside of the tablet or between two tablets interconnected back-to-back. In various embodiments, the tablets comprise at least one surface with an array of touch fastening elements allowing the backs of the tablets to be removably engageable to one another.
In one embodiment of the present invention, a selectively movable writable surface is provided, including a flat support surface and a re-adherable writing board releasably interconnected thereto. The writing board includes a flexible rectangular board having a substantially blank front surface and a rear surface within an outer boundary. The flexible board is substantially flat in an unflexed configuration and the front surface is a polyethylene terephthalate dry-erase surface.
In various embodiments the tablet assembly comprises a tablet that can interconnect to and detach from a mounting assembly. The tablet comprises a tray with an upper surface, a frame, and an insert. The frame has a brick connection rear surface and a plurality of magnets. The mounting assembly has a mounting bracket, indentions, protuberances, lips, and ferrous metal rivets. The frame interconnects to the mounting assembly via the magnets attracting and interconnecting to the ferrous metal rivets, which align with the magnets. The magnets of the tablet allow the tablet to interconnect to another tablet side-by-side or back-to-back and interconnect to the mounting assembly. Additionally, the tablet can interconnect to any ferrous metal surface.
In one embodiment, the tablets comprise magnets to releasably interconnect two or more tablets to one another back-to-back or side-by-side. In additional embodiments, the sides of the tablets also comprise recesses, slots, or indentations to further align and interconnect multiple tablets to one another side-by-side.
Some embodiments of the tablet include a rewritable surface comprising a coating of hydrophilic silane or a hydrophilic water soluble polymer with hydroxyl groups which is crosslinked or chemically reacted to the surface. In one embodiment, a method of treating a writing surface to impart rewritable properties thereto is provided. The method includes applying a hydrophilic coating composition to the surface to bond to the —OH groups on the surface, where the hydrophilic coating composition includes alkoxysilane groups and/or silanol-functional groups bonded to a zwitterion, anion, cation, carbohydrate, or a hydrophilic polymeric moiety. The hydrophilic coating composition can also contain lithium silicate, sodium silicate, potassium silicate, or combinations thereof. The method further includes drying the hydrophilic coating composition to form a hydrophilic coating including at least a monolayer of the hydrophilic compound bonded to the writing surface through siloxane bonds.
In one embodiment of the present invention, the tablets can have electronic components such that the information written on the tablets can be transferred to a computer or computing device or to a larger screen. Thus, the writing tablets may accept input data through a touch-sensitive surface. In an alternate or additional embodiment, the tablet with electrical components can display images or information on the tablet's upper surface.
In some embodiments, the electronic tablet comprises a processor, memory, an input device (which can be a touch-screen display surface configured to receive touch input), a display to display content, and a power source (which can be a battery). The tablet can further include data storage, software, a user interface, an input device, an output device, a communication network, such as Bluetooth or WiFi, and/or a communication interface for communicating with another tablet or computing device and/or the communication network. The display can include an overlayed electronic skin. The display can include an outer transparent display surface and can be placed in a dark state or in a bright state similar to the display described in U.S. Patent Publication No. 2010/0245221 to Khan, which is incorporated by reference herein in its entirety.
In further embodiments, the processor can include any processor capable of performing instructions encoded in software or firmware. Further, the processor can be provided to execute instructions contained within the memory and/or data storage. The processor can comprise a controller or application specific integrated circuit (ASIC) having or capable of performing instructions encoded in logic circuits. The memory may be used to store programs or data, including data comprising content. As examples, the memory may comprise RAM, SDRAM, or other solid state memory. Alternatively or in addition, data storage may be provided. The data storage may generally include storage for programs and data.
In one embodiment, the tablet further includes an interactive electro-optic display device used in combination with a transparent graphics tablet device providing an electronic writing surface for an integrated display-tablet operation. A person using the tablet or tablet system can hand sketch, write, and draw onto an electronic writing surface, and the system converts this information to electrical signals for display on a viewing screen directly under the transparent graphic tablet.
In another embodiment, the tablets can comprise an elastic sleeve situated between two tablets positioned side-by-side to provide a housing for the flexible circuit connecting the two tablets. The flexible circuit interconnection mechanism may provide pathways for coupling the tablets and include an electrical conductor, an optical path, electromagnetic waveguides, fluidic channels, magnetic couplings, mechanical couplings, and so forth. A magnet can be positioned along the edge and back side of one side of the first tablet to provide a lock for both tablets when interconnected to a second magnet positioned on the edge and back side of the second tablet allowing the two tablets to snap together without extra, bulky hardware, such as mechanical hinges. Sensors can be positioned adjacent to the magnets to determine whether or not the tablets are interconnected and to determine how the tablets are arranged or interconnected to one another, i.e., which side of each tablet is connected to another tablet and where in the system of tablets each tablet is located.
In an alternate embodiment, there is not a physical connection between two tablets. Thus, the tablets can be charged and/or powered through the mounting assemblies. Additionally, the tablets can receive relevant data (e.g., position in a wall system) from the mounting assemblies or the tablets can self-actualize their positions using near field communication (NFC) or other wireless proximity sensors between the tablets.
In one embodiment, the tablets may comprise hinges, mini stands, flaps, hooks, straps, adjustable mounting brackets, or another positioning mechanism that allow one or more tablets to be positioned at an angle relative to a horizontal surface. Thus, the tablet may be positioned at an angle relative to a horizontal surface (e.g., a table top) for ease of viewing, similar to a case or a stand for an electronic reader that positions the reader in an upright position.
In one embodiment, the tablet may comprise a coupling mechanism that allows the rotation of each tablet relative to another tablet such that any angle between 0 degrees and 360 degrees can be achieved. In addition, the coupling mechanism can allow the angle to be maintained by a damping means. For example, two tablets coupled together can therefore be rotated with their positions maintained by the damping means such that the writing surfaces of both tablets face each other, or face outward and away from each other, as well as achieve any position in between.
In another embodiment, one side of the hinging mechanism may comprise a component with a larger outer perimeter that slides over a component with a smaller inner perimeter. A third locking component may also be present to secure the previous two components together, while allowing rotation of the tablets relative to each other. In one embodiment, the hinge may unclip to allow the two tablets to separate completely.

As described in detail below, various embodiments of the present invention include novel writing tablet designs and configurations comprising interconnection features and/or other features. The present invention has significant benefits across a broad spectrum of endeavors. It is the applicant's intent that this specification and the claims appended hereto be accorded a breadth in keeping with the scope and spirit of the invention being disclosed despite what might appear to be limiting language imposed by the requirements of referring to the specific examples disclosed.
In one embodiment, the insert 22 is a thin film and the tablet is digital. Thus, the thin film can be a film similar to the films used in screens of electronic tablets such as Kindles, iPads, etc. The film will enable the tablet 12 to have a low powered display. Accordingly, the tablet 12 can still have a smooth, upper surface for writing and have the thin film behind the tray 24 and writing surface. Therefore, images could be displayed on the tablet 12 and users could write on top of the images. Further, the film enables the tablet 12 to act as a portable black and white electronic reader. Adding electronic components to the tablets 12 enable the system to be used as modular signage. For example, a map could be displayed on the tablets 12, and then the map could change to lines, graphs, directions, etc. at the touch of a button. Further, adding electronic components to the tablets 12 and system can create a smart board if the tablets 12 know where they are positioned within the system. For example, a first tablet 12 would know it was positioned on an upper right corner and a second tablet would know it was positioned on a lower left corner. The tablets 12 must further know if and to where they are moved within the system. Additionally, if electronics are added to the tablets 12, then the tablets 12 will need displays (such as display screens to display digital content), power sources (which can be batteries, for example), processors, memory (which can include data storage), software, electrical circuits, etc. to operate the tablets 12 and system.
The aperture 54 of the frame 24 receives the protuberance 42 of the tray 20 to form a snap-fit interconnection between the tray 20 and the frame 24. The interconnection between the aperture 54 and the protuberance 42 can more clearly be seen in
The frame 24 can be manufactured of any material known in the art, such as plastic, metal, or composite material. In one embodiment, the frame 24 is composed of thermoplastic material, which can be any thermoplastic such as acrylonitrile butadiene styrene (ABS). The frame 24 may be clear, opaque, or colored. In one embodiment, the frame member is black ABS. In another embodiment, the frame member is clear polycarbonate.
The wall 64 has one or more magnets 26 in each side. In the embodiment shown, the wall 64 has two magnets 26A, 26B on each side, where one magnet is a positively oriented magnet 26A and one magnet is a negatively oriented magnet 26B. The magnets 26 alternate positively oriented magnet 26A and negatively oriented magnet 26B around the wall 64 such that the magnets 26 will attract magnets 26 of the opposite polarity on other tablets 12 if two tablets 12 are interconnected back-to-back or side-by-side. Using magnets 26 to interconnect two or more tablets 12 allows the tablets 12 to align properly and easily. Additionally, the tablets 12 are easy to disconnect. The embodiment shown in
The magnets 26A, 26B can be inserted into the frame 24 from the underside of the frame 24 in one embodiment. The magnets 26A, 26B can be glued into the frame 24 or held in the frame 24 through a mechanical fit, such as a tension-fit, snap-fit, or friction-fit. In other embodiments, the magnets 26A, 26B are secured within the frame in any manner known in the art such that the magnets 26A, 26B are positioned proximate to the perimeter of the frame 24 and positioned proximate to the underside of the frame. The position of the magnets 26A, 26B enables two or more tablets 12 to interconnect to one another back-to-back and side-by-side.
The wall 64 has curves on an inner side of the wall, the side proximate to the rear surface 60 of the frame 24. The curves assist a user in gripping the tablet 12 and frame 24. Thus, the curves of the wall 64 may be sized and shaped to fit a user's fingers.
The lower portion 78 of the side of the frame 24 curves inward and the magnet holders 52 protrude at least partially from the side of the frame 24, as can be seen in
The length L1 of the frame 24 is between 200 mm and 400 mm in one embodiment. The length L1 of the frame 24 is between 250 mm and 350 mm in a preferred embodiment. The length L1 of the frame 24 is between 275 mm and 300 mm in a more preferred embodiment. The length L1 of the frame 24 is about 280.0 mm in a most preferred embodiment. The length L2 between two magnets 26 is between 50 mm and 100 mm in one embodiment. The length L2 between two magnets 26 is between 75 mm and 85 mm in a preferred embodiment. The length L2 between two magnets 26 is about 80.0 mm in a more preferred embodiment.
Each rivet 92 is positioned at the end of a leg 108 and is positioned to align with a magnet 26 of the tablet 12. The mounting bracket 90 comprises a first radius R1 and a second radius R2. The second radius R2 is chosen such that when four mounting assemblies 14 are interconnected to one another, the second radius R2 forms a circle (see
The mounting assembly 14 further includes a lip 100 on an end of at least one leg 108 to prevent the tablet 12 from sliding off of the mounting assembly 14 when the mounting assembly 14 is positioned in a substantially vertical position and a user pushes on a corner of the tablet 12 to release the tablet 12 from the mounting assembly 14. Without the lip 100, the tablet 12 would likely slide off of the mounting assembly 14 when the user pushed on a corner of the tablet 12, which would likely cause the tablet 12 to slide into other tablets 12 and possibly knock the other tablets off of the wall or mounting assemblies 14. In one embodiment, each leg 108 has a lip 100 at the end of the leg 108. Further, the lip 100 can be curved-shaped and positioned in a corner of the leg 108 closest to a corner of the tablet 12. The curve of the lip 100 matches the bow or curve of the magnet holder 52 in the frame 24 so that the lip 100 does not hinder the positioning and interconnection of the frame 24. In one embodiment, the lip 100 has a height of between 0.75 mm and 1.75 mm above the upper surface of the mounting bracket 90. In another embodiment, the lip 100 has a height of between about 1.0 mm and 1.5 mm above the upper surface of the mounting bracket 90.
The mounting bracket 90 can be manufactured of any material known in the art, for example, plastic, metal, or composite material. In one embodiment, the mounting bracket 90 is composed of thermoplastic material, which can be any thermoplastic such as acrylonitrile butadiene styrene. The rivet 92 can be a pin, nail, or other ferrous metal item secured within or on the mounting bracket 90 to interconnect to the magnet 26 of the tablet 12. The rivet 92 can be a tension-fixed rivet 92 or it can be glued or adhered to the mounting bracket 90.
The combination of the height of the lip 100 of the mounting bracket 90, the magnet/rivet distances L2, L5, and the strength of the magnets 26 prevent the tablet 12 from falling off of a mounting assembly 14 positioned on a vertical surface, while allowing a user to easily remove the tablet 12 from the vertically mounted mounting assembly 14.
The multiple mounting assemblies 14A-I and tablets 12A-F are interconnected to one another. In the embodiment shown, multiple tablets 12A-F can be interconnected to one another, arranged, and rearranged depending on the user's needs. Accordingly, if one tablet 12 contains information that would make more sense positioned in a different location relative to the other tablets 12, then the one tablet 12 can easily be disconnected, moved, and re-interconnected to a different mounting assembly 14 and the other tablets 12.
The tablets 12A-F are easily detachable from the mounting assemblies 14A-I by pushing on a corner of the tablet 12 because the mounting assemblies 14A-I do not extend to the corners of the tablets 12A-F. Specifically, a user can push on a corner of the tablet 12 to detach the tablet 12 from the mounting assembly 14 without detaching other tablets 12A-F if the tablet 12 is in a system of tablets 12A-F secured to a vertical wall because only the one tablet 12 upon which the user pushed will detach from its mounting assembly 14.
In an alternate embodiment, to allow the tablet 12 to be easily removed from a wall, especially a middle or center tablet in a system of multiple tablets 12, the corners of the tablet 12 may be shorter (i.e., shorter in height) than the sides of the tablet 12. Thus, a portion of the bottom surface 74 of the sides of the tablet 12 may be angled such that the side is the shortest at an edge or end, i.e., a corner. The angled bottom edge allows a user to push on one corner of the tablet 12 and pop the opposite corner of the tablet 12 off of the wall, table, or other surface. Angling the bottom edge of the tablet 12 allows the tablet 12 to rock when a user pushes on one corner of the tablet 12 such that the opposite corner lifts up in an amount equal to the amount that the one corner is pushed downward, if the pivot point is positioned in the exact center of the tablet 12. However, in one embodiment the tablet pivot point is off center, creating a lever by which the corner upon which the user pushes downward travels a shorter distance than the distance the opposite corner lifts upward. In an alternate embodiment, the tablet 12 may be flexible and able to be bent to pull the tablet 12 away from the wall or mounting bracket 14. Alternatively, only the writing surface of the tablet 12 may pop out and the tablet base may stay secured to the wall.
Other clip shapes may be used to hold papers, business cards, folders, phones, electronic tablets, make-up, etc. Thus, when two erasable writing tablets are interconnected back-to-back, accessories and/or materials may be stored in the space between the two erasable writing tablets. Accordingly, the writing tablets are a combination of a writing device and purse-like device by interconnecting two or more tablets together to hold materials between the tablets, such as sheets of paper and pens. In one embodiment, the tablets may have a handle that can be rotated from an underside or interconnected to the tablets to assist in carrying the purse-like combination of tablets. The two tablets may be secured to one another using magnets, hinges, hooks, hook and loop material, straps, clips, buckles, alignment locking mechanisms, or other interconnection mechanisms known in the art. In one embodiment, the erasable writing tablets are equipped with hinges such that they may be foldably interconnected through the hinges and are capable of transforming between a flat system of tablets and a tridimensional system of tablets.
