1. Field of the Invention
The present invention relates generally to a device for presentation, and more particularly to a desk with a retractable board and the retractable device.
2. Description of the Related Art
In assembly room, there are a desk a couple of chairs and a white board. People can write on the white board for presentation. The white board usually takes a lot of space that might take the path of walking.
In many companies, there are a couple of assembly rooms bit only have one white board. The white board has to be moved between the rooms that also makes inconvenient.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a desk with a retractable board that take less space of the assembly room.
The secondary objective of the present invention is to provide a retractable board assembly to be mounted on any desk, such that the desk can provide a white board when necessary.
According to the objectives of the primary present invention, a desk of the present invention has a plank member with two parallel rails and a retractable board provided on the rail for movement. The retractable board is moved between a retracted condition and an extended condition. When the retractable board is moved to the retracted condition, the retractable board is located in the desk, and when the retractable board is moved to the extended condition, the retractable board is moved out of the desk and substantially perpendicular to the plank member.
According to the objectives of the secondary present invention, a retractable board device includes a base to be fixed to a desk, on which two rails are mounted. A retractable board is engaged with the rails for movement. The retractable board is moved between a retracted condition and an extended condition. When the retractable board is moved to the retracted condition, the retractable board is located in the base, and when the retractable board is moved to the extended condition, the retractable board is moved out of the base and substantially perpendicular to the base.
10. The retractable board device as defined in claim 9, wherein the base has a plate, on which the rails are provided, and a cover mounted on the plate to mask the rails.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in
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
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
As shown in
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
