DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 2 and 3, the system for rising and storing a monitor 20 comprises a box 1 having a space 11 defined therein and a top hole 12 is defined in a top of the box 1. The top hole 12 communicates with the space 11. The box 1 is located beneath a top 10 of a desk and an opening 101 is defined through the top 10. The top hole 12 communicates with the space 11.
A motor 22 is located in the space 11 and a guide rail 21 is located on an inside of the box 1. A base 3 connected with a monitor 20 is located in the space 11 and the monitor 20 drives by the motor 22 along the guide rail 21 so that the monitor 22 can be moved upward through the top hole 12 of the box and the opening 101 of the top 10 of the desk, or be lowered and stored in the box 1.
A link mechanism 5 received in the box 1 and includes a transverse bar 52, two first frames 51 on two opposite insides of the box 1, two first links 53, two plates 56, two second links 55 and two second frames 54. Each first frame 51 has a first slot 511 defined therein and two ends of the transverse bar 52 are movably engaged with the two first slots 511 of the two first frames 51. The base 3 is rested on the transverse bar 52 when the monitor 20 is stored in the box 1. The two first link 53 are on the two opposite insides of the box 1 and each first link 53 has a first end pivotably connected to one of the two ends of the transverse bar 52. A protrusion 531 extends laterally from the first link 53.
The two plates 56 are pivotably connected to two supports 13 on the two opposite insides of the box 1 at two respective mediate portions of the two plates 56, so that the first end and the second end of each plate 56 can be moved up and down about the mediate portion. A second end of each first link 53 is pivotably connected to the first end of the plate 56 corresponding thereto. The two second frames 54 are connected to the two opposite insides of the box 1 and each second frame 54 has a second slot 541 defined therein. Each second slot 541 includes a curved trace 5411. The two second frames 54 are located higher than the first frames 51 in vertical direction relative to a horizontal direction.
The two second links 55 each have a first end pivotably connected to the second end of the plate corresponding thereto and a second end of each second link 55 is movably engaged with the second slot 541 of the second frame 54 corresponding thereto.
A cover 4 removably closes the opening 101 of the top 10 of the desk and has two side portions 41 extending vertically from two ends of the cover 4. The two side portions 41 are pivotably connected to the two respective second ends of the second links 55. Two springs 57 are connected between the protrusions 531 of the two first links 53 and the two supports 13 of the two plates 56 so as to exert an upward force to the transverse bar 52.
As shown in FIG. 4, when the monitor 20 is stored in the box 1, the base 3 is rested on the transverse bar 52 and the first links 53 are located at the lower ends of the first slots 511 in the first frames 51. The first end of each plate 56 is at the low position while the second end of each plate 56 is located at high position, and the second links 55 push the two side portions 41 of the cover 4 to close the top hole 12 of the box 1.
As shown in FIG. 5, when the monitor 20 is driven by the motor 22 to move upward, the base 3 is removed from the transverse bar 52 and the springs 57 pull the first links 53 and the transverse bar 52 upward along the first slots 511. The plates 56 are then pivoted about the two respective mediate portions, so that the second links 55 are moved downward along the second slots 541. The second links 55 pull the side portions 41 of the cover 4 downward vertically. After the cover 4 is received in the box 1, the second links 55 together with the side portions 41 move along the curved trace 5411 and the cover 4 is pivoted an angle. Therefore the top hole 12 is needed to be made the same size as the cover 4.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
