The present invention provides tablets with interconnection features and a system of multiple tablet assemblies removably interconnected to one another. The tablets may be removably mounted to a vertical surface or positioned on a horizontal surface. Features of the present invention allow a user to remove or move one tablet from the system without disrupting or moving the other tablets.

Disclosed are a method and/or a system of a flippable board. In one aspect, the flippable board includes a track capable of attaching to a surface, a first hinge component and a second hinge component attached to the track, and a frame attached to the first and second hinge components along a first vertical end of the frame. The first and second hinge components allow the frame to rotate between an open position and a closed position. The flippable board further includes an adjustable left magnet and adjustable right magnet attached to the first and/or second hinge component, and at least one metal sleeve attached to a second vertical end of the frame capable of connecting to the left magnet and/or right magnet of a secondary flippable board and/or an adjustable surface magnet in order to secure the flippable board in the open and/or closed position.

A whiteboard assembly having a wall mount assembly and at least one panel assembly. The wall mount assembly being attachable to a wall and including a plurality of wall mount members. The panel assemblies each including a panel member and an attachment assembly. The panel member having a front and back surface and an outer perimeter. The attachment assembly having a plurality of attachment members coupled to the panel member. The panel member attachable through the attachment members to the wall mount assembly. A second panel member having substantially the same structural configuration is attachable to the first panel member through the respective attachment members. Methods of use are likewise disclosed.

A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.

An apparatus for connecting a writing implement to a glassboard, whiteboard or the like that has a housing adapted to be connected to a writing implement. The housing has a side surface with an opening formed therein and a recess extending from the opening into the housing. A magnet is disposed in the recess and has a first pole at the opening. The magnet provides a magnetic field in a direction away from the side surface of the housing. The apparatus enables a side periphery of a writing implement coupled with the apparatus to magnetically couple with the glassboard, whiteboard or the like in a predetermined orientation regardless of the initial orientation of approach of the writing implement.

The invention relates to glass articles suitable for use as writable erasable marker boards. More particularly, disclosed is a strengthened glass article suitable for use as a writable erasable marker boards, wherein the glass sheet exhibits an ion exchanged glass having a front surface and a back surface and exhibiting a thickness of less than 2.0 mm and having a depth of layer (DOL) greater than 20 microns and a surface compressive strength of at least 300 MPa. The strengthened glass article exhibits certain optical properties which render it particularly suitable for use as a writable erasable marker boards electronic including: (1) shadow parallax to thickness ratio of less than 1 measured at a 60 degree incident light angle and for an index of refraction n; and, (2) a haze of less than 50%. Further disclosed is a markerboard with improved magnetic force attributes; sufficient to hold weak magnets in place.

A calendar system including a ring-bound paper calendar having a plurality of paper calendar sheets secured to a ring binding mechanism, the paper calendar configured such that each paper calendar sheet can be exposed by flipping the sheets above it out of the way using the ring binding mechanism, and a transparent dry erase sheet detachably coupled to the calendar, the transparent dry erase sheet configured, when detachably coupled to the paper calendar, such that the dry erase sheet can be placed on top of an exposed paper calendar sheet to permit a user to view the paper calendar sheet below the transparent dry erase sheet, wherein the user may write directly onto the exposed paper calendar sheet in a permanent manner, and write on the transparent dry erase sheet in a semi-permanent manner.

A writing board for mounting to a structure includes a main panel made from transparent material, the main panel having a front writing surface and a rear surface. There is at least one holding device formed in the rear surface for holding a background material. The front writing surface is flat and the entire background material is completely visible through the main panel.

A playboard includes a first ferromagnetic metal plate, a first coating on an outer side of the first ferromagnetic metal plate, a first polyolefin film adhered to the inner side of the first ferromagnetic metal plate, a layer of low density polyethylene on the first polyolefin film adhered to the inner side of the first ferromagnetic metal plate, a second polyolefin film adhered to the layer of low density polyethylene on the first polyolefin film adhered to the inner side of the first ferromagnetic metal plate. The playboard preferably has a mounting means to secure the playboard to a wall. For example, the mounting means may be double sided tape and/or a hook and loop fastener.
