  • FIG. 10 is a perspective view of a part of the fourth preferred embodiment of the present invention.
    • DETAILED DESCRIPTION OF THE INVENTION
  • As shown in FIG. 1 to FIG. 5, the first preferred embodiment of the present invention provides a desk 10 having a plank member 12 with a slot 14 on a bottom thereof. The slot is open at the bottom and an edge of the plank member 12 and has two sidewalls 16. Two rails 18 are mounted on the sidewalls 16 respectively.
  • A retractable board 20 has a base board 22 and a movable board 24 connected together by hinges 26, such that the movable board 24 is tuned relative to the base board 22. A ratchet device 28 is provided between the base board 22 and the movable board 24, such that the movable board 24 can be fixed at any angle. The base board 22 and the movable board 24 have sliding members 30, 31 on opposite edges respectively to be engaged with the rails 18, such that the base board 22 and the movable board 24 can slide along the rails 18.
  • In a retracted condition, as shown in FIG. 1 and FIG. 3, the movable board 24 is turned 180 degrees relative to the base board 22 and both of the base board 22 and the movable board 24 are received in the slot 14 of the plank member 12. In use, the movable board 24 is drawn out of the slot 14 and disengaged with the rails 18, and the base board 22 has a portion still received in the slot 14 and engaged with the rails 18. Now, the movable board 24 is turned upwards about 90 degrees to an extended condition, and the ratchet will fix the movable board 24 at the extended condition, as shown in FIG. 4.
  • In the retracted condition, the desk 10 of the present invention is as same as the normal desk. In the extended condition, the desk 10 of the present invention has the vertical movable board 24 at an edge of the desk to be used as white board, show board, screen (for projector) and the like.
  • As shown in FIG. 5, a desk 32 of the second preferred embodiment of the preset invention, which is similar to the desk 10 of the first preferred embodiment, except that a movable board 34 is pivoted with two extended boards 36 on opposite edges along a horizontal orientation. In a folding condition, the extended boards 36 are turned inwards and rested on the movable board 36. In an extended condition, the extended boards 36 are turned outwards for 180 degrees, such that we will have the board with greater area on the desk 32.
  • FIG. 6 shows a desk 38 of the third preferred embodiment of the preset invention, which a movable board 40 has an extended board 42 pivoted on a top thereof. In a folding condition, the extended board 42 is turned downwards and rested on the movable board 40. In an extended condition, the extended board 42 are turned upwards for 180 degrees, such that we will have the board with greater area on the desk 38.
  • As shown in FIG. 7 to FIG. 9, the fourth preferred embodiment of the present invention provides a retractable board device 44. The retractable board device 44 has a base 46 and a retractable board 54. The base 46 includes a plate 48, on which two parallel rails 52, and a cover 50 to mask the rails 52. The retractable board 54 has a base board 56 and a movable board 58. The base board 56 and the movable board 58 have sliding members 60, 61 respectively to be engaged with the rails 52, such that the base board 56 and the movable board 58 can slide along the rails 52.
  • The plate 48 of the base 46 is provided with bores 62 to fix the retractable board device 44 of the present invention on a bottom of a plank 66 of a desk 64 by screws. As same as above, the movable board 58 may be drawn out and turned upwards to form a vertical board at an edge of the desk 64.
  • As shown in FIG. 10, the base board 56 has a fixed portion 68 with two holes 70, 72, and the movable board 74 has a hole 74. While the movable board 58 is turned downwards and upwards, the hole 74 of the movable board 74 is aligned with the holes 70, 72 of the base board 56 respectively, such that a pin 76 can be inserted into the holes to fix the movable board 58 in horizontal condition and vertical condition.
