This invention relates generally to a writing board, and more particularly to a mounted flippable writing board.
A writing board may be a board used to temporarily write things down on. Users may decide to mount writing boards on walls. However, users may wish to be able to hide what is written on the writing boards from time to time on a temporary basis. This may require installing additional cabinets and/or structures in order to cover the writing boards mounted to the walls.
Alternatively, free standing writing boards may be used which can be flipped from front to back. However, this may take additional floor space and/or create hazards within a space. Therefore, free standing writing boards may be cumbersome, unsightly and/or dangerous.
Further, users of mounted writing boards may find that the mounted writing boards and/or the open floor space create poor acoustics. The users may need to install additional hardware and/or structures in order to improve the acoustics within the space. Therefore using a mounted writing board with a single surface may be burdensome, cumbersome, and/or costly when additional privacy and/or acoustic structures are needed.

Circle ‘4’ shows, according to some preferred embodiments, that the acoustic panel 300 is visible in the closed position 406. The acoustic panel 300 may provide acoustic benefits, suppressing sound in the room. Further, by having the acoustic panel 300 visible in the closed position 406, the writing board 136 is hidden from view and provides privacy when the user does not want material written on the writing board 136 to be seen. In yet further embodiments, as shown in Circle ‘4’, the track 102 is not visible when the flippable board 100 (e.g., the primary flippable board 400) is in the closed position 406, providing a more pleasing aesthetic.
According to some embodiments, the metal sleeve of a flippable board 100 without an adjacent board on one side (e.g., the secondary flippable board shown in Circle ‘6’) may connect to a surface magnet 134 attached to the surface 104. Circle ‘6’ shows that the surface magnet 134 is located at a specific distance from the secondary flippable board 402 of Circle ‘5’ such that the metal sleeve 126 will align with the surface magnet 134 when the secondary flippable board 402 is rotated into the open position 404, according to some embodiments. In some preferred embodiments, when the metal sleeve 126 connects to the left magnet 114 and/or the surface magnet 134, the connection will hold the flippable board 100 (e.g., the primary flippable board 400 and/or the secondary flippable board 402) in the closed position 406 in a stable condition such that the flippable board 100 will not moving out of position without the user intending such.
Further, in Circle ‘7’ the track 102 is attached to surface 104, according to various embodiments. In Circle ‘8’ the first hinge component 106 and the second hinge component 108 are capable of allowing the frame 110 to rotate between an open position 404 and/or a closed position 406 about an axis along the first vertical end of the frame 112. In Circle ‘9’ the metal sleeve 126 connects to secondary flippable board 402 and/or a surface magnet 134 in order to secure the flippable board 100 in the open position 404 and/or the closed position 406 according to one embodiment.
An example embodiment may now be described. Sofia may be the owner of a new business, So Soft. Sofia may want her employees to use glassboards for collaborating and/or writing down their ideas throughout the work day. Sofia may have ordered two dozen free standing glassboards and two dozen mountable glassboards from Gary Glassboards to use throughout the office. Later, Sofia may realize that clients often come into the office and are able to view sensitive material written on both the free standing glassboards and the mounted boards. Sofia may find it cumbersome to cover the mounted glassboards and/or move the free standing glassboards. Sofia may be able to flip the free standing glassboards to an empty side thereby hiding the material from view. Sofia may look into purchasing cabinets that will hide the mounted glassboards from view when she does not want them to be seen, however, she may find that she cannot bear the additional cost and/or may find the cabinets unsightly.
Further, Sofia may realize that the free standing glassboards interfere with her vision of creating an open workspace environment. While the mounted glassboards may promote the open workspace environment, Sofia may also realize that the open space creates poor acoustic conditions and it is often difficult to hear colleagues when multiple employees are holding conversations at the same time. Sofia may look into purchasing acoustic panels that will help to dilute the sound in the office, however, she may find the installation of the acoustic panels to be too costly, time intensive and/or cumbersome when used in addition to the mounted glassboards.
Thankfully, Sofia may learn that Gary is selling the new flippable boards (as described in

The structures and modules in the figures may be shown as distinct and communicating with only a few specific structures and not others. The structures may be merged with each other, may perform overlapping functions, and may communicate with other structures not shown to be connected in the figures. Accordingly, the specification and/or drawings may be regarded in an illustrative rather than a restrictive sense.
