[0031] FIG. 1 generally depicts the basic architecture of an adjustable writing board in accordance with the one of the disclosed embodiments.

[0032] In one embodiment, an adjustable writing board 100 comprises a planar member 101 having a front face 102, a rear face 103 opposed to the front face, two side edges 104 and 105 slidably engaged with a first station 106 and a second station 107 respectively; a third station 108 slidably engaged with a middle portion of the planar member 101; a remote control panel electrically connected with the first station 106, the second station 107, and the third station 108 to control operations thereof; wherein each of the first station 106, the second station 107, and the third station 108 comprises a slide guiding rail 109 and a wheel roller slidably received in the slide guiding rail.

[0033] When the writing board 100 are in use, at least one of the first station 106, the second station 107, and the third station 108 may be affixed on a wall. For example, the planar member 101 of the writing board 100 may be eight feet in length and four feet in height, which may be either a chalk or white board. Each station may be eight feet in height, vertically installed one foot above the ground. The length and height may be adjusted according to the using situation and by ordinary means.

[0034] When adjusting the position of the writing board 100, at least one of the two side edges 104 and 105 of the planar member 101 are vertically moved along the first station 106 and second station 107, at least one of the two side edges 104 and 105 and the middle portion of the planar member 101 are syncronizedly moved along the first station 106, the second station 107, and the third station 108 at the same level.

[0035] FIG. 2 demonstrates the side view of the adjustable writing board, specifically a locking mechanism 200 having a slide guiding rail 205, a wheel roller 204 slidably received in the slide guiding rail 205, and a plurality of stoppers (201-203), which can retract and contract to block and release the wheel roller 204. Wheel roller 204 rolls up and down inside the slide guide rail 205 until in desired position. The slide guide rail 205 guides the writing board up and down in a fixed position. That is, by manually pushing or pulling the planar member 101 up and down, the wheel roller 204 will also roll up and down inside the slide guide rail 205 until the planar member 101 is in desired position.

[0036] Please also refer to FIG. 8, which demonstrates how a remote control panel connect with the components on adjustable writing board. When the writing board are adjusted by the remote control panel 310 which electrically connected with a first station 304, a second station 305, and a selective third station to control operation, the stopper 201 retracts when under pressure from the wheel roller 204, the stopper 202 contracts when not under pressure from the wheel roller 204. In detail, the remote control panel 310 is connected to a motor (not shown in the figure), which located in/on the adjustable writing board, and the remote control panel 310 will control the motor to drive the wheel roller 204 to move up and down in the slide guiding rail 205. In this embodiment, the remote control panel 310 is located on the planar member 101, but it can also located on the the first station 106 and second station 107.

[0037] Please refer to FIG. 7 demonstrates the side view of the adjustable writing board in another embodiment. FIG. 7 shows the stoppers 203 can also be spring-loaded, and the spring-loaded stopper 203 keeps the writing board in desired position. In other words, because the spring is loaded on each of the stoppers (201-203), the wheel roller 204 cannot overcome the spring's elastic recovery force and move up and down without applying external force. Therefore, the wheel roller 204 will be stuck by the stoppers 203 and cannot adjust the height for the writing board. However, when an external force is applied to the wheel roller 204, such as manually pushing or pulling the planar member 101 up and down or the remote control panel 310 controls the motor to drive the wheel roller 204 to move up and down, the stopper 201 in the moving direction of the roller will be pushed outward, causing the spring on it to be compressed so that the wheel roller 204 can pass through, and when the wheel roller 204 leaves, the stopper 202 returns to its original position through the elastic recovery force of spring.
