Superior usability is provided and the degree of freedom in terms of use is enhanced. A plurality of link members A1 and A2 include at least one of linear edges A12 and A22 at the peripheral edge of a facing surface A10 or A20 that faces in a folded state. At least one of the adjacent link members A1 and A2 is a magnet, and the other is a material attracted by the magnet. A link body A is formed of the link members A1 and A2 that are linked by the attracting force due to the magnetic force of the link members A1 and A2, of which the linear edges A12 and A22 are aligned.

The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions.

A mobile writing board system includes a frame extending from an upper portion to a lower portion; a writing board secured to the frame; a module secured to the lower portion of the frame; and a mobile device secured to the lower portion of the frame. The mobile device includes a housing; and a plurality of wheels configured to move within the housing while in a stationary position and configured to extend outside the housing during transit.

There is provided to a tilt board (1, 51, 61, 101) comprising an activity surface (3) supported by a base (5). The base comprises a front wall (7) and a rear wall (9) that extends downwardly from the activity surface by a greater distance than the front wall. The activity surface (3) comprises an activity surface surround (15) defining an aperture (17) therein and a removable activity surface insert (19) dimensioned for reception in the aperture. A plurality of interchangeable activity surface inserts (19) may be provided. The activity surface inserts (19) are also tilt adjustable relative to the remainder of the tilt board. The tilt board (1, 51, 61, 101) is provided with a circumferential flange so that the tilt board may be inserted into an aperture of a larger work surface such as a table if desired. The tilt board can be used for a range of activities, can lie flat in a larger work surface if desired, and the tilt angle can be adjusted to several angles which is highly advantageous.

A slope adjustable illuminated art and drafting table for drawing, writing, or impromptu sketching on large documents enables efficient access and storage of artistic or drafting supplies. The art and drafting table provides a base supported by a pair of arced legs. A work surface overlays the base. The work surface is illuminated and pivotally adjustable to slope between 0 and 35. A hinged angle adjustment bracket fastens the work surface at the desired slope. The drafting table provides modular lower drawers that are interchangeable between left and right sides of the drafting table; an extendable shelf having a longitudinal lip for retaining marking instruments; and a pair of elongated partitioned lateral trays at the lateral edges of the work surface. The partitioned lateral trays are detachable and have depressions for holding artist instruments, paints, writing instruments, and other materials used by artist and draftsmen.

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.
