Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a lift screen, and, particularly to a lift screen used in an office.




2. Description of Related Art




Due to the expensive rent of an office of an office building in a city, how to use a limited office space effectively and to keep personal privacy off being bothered by way of a screen is a vital subject worth us to care. The Chinese Utility Model Application No. 00238270.9 filed by the present inventor discloses a lift screen as shown in

FIG. 1

provides a lift mechanism (not shown) disposed in a interaction


2


of a screen base


1


and a partition board


3


with an upper cover


4


is provided on a support of a lift mechanism. When a manual handle bar


5


is turned, the lift mechanism can actuate the partition board


3


to move upward or downward. Hence, the prior art is a screen being operated easily with high mobility and the screen can be associated with a worktable as a counter in a bank or for ordinary business purpose. Besides, a mirror or a monitor can be used instead of the partition board such that the lift screen becomes a dressing table or a display for an electronic product. However, the prior art is not so compact and so handy and it is worth us to make an improvement.




SUMMARY OF THE INVENTION




An object of the present invention is to provide a lift screen, which is possible to be set up into multiple forms with multiple functions so as to offer a high mobility and more flexibility while in use and to be set up into a form with a worktable, so as to satisfy various needs and desired arrangements.




In order to reach the preceding object, the lift screen of the present invention comprises: an upright post, being hollow body; a lift mechanism, being disposed in the upright post; and a partition board, providing at least a slide plate at a facial side thereof, and a lower side thereof connecting with the lift mechanism.




The preceding lift screen further has a plurality of guiding catch grooves provided at the periphery of the upright post with the slide plate being inserted into one of the guiding catch grooves in a way of slide fit with the guiding catch groove, and an elongated trunking plate at both ends thereof providing a retaining pin or an arched retaining pin respectively being inserted into another one of the guiding catch grooves.




The preceding lift screen further has the respective guiding catch groove providing a top fitting hole.




The preceding lift screen further has the respective guiding catch groove providing a plurality of post fitting holes.




The preceding lift screen further has the arched retaining pin provides a first, a second and a third plane; the first plane is a arched plane with a retaining pin, the second and the third planes are flat and perpendicular to each other; and the third plane may provide a joint to fit with a recess at an end of the trunking plate.




The preceding lift screen further has a base being provided and the base is a worktable.




The preceding lift screen further has the partition board at an upper side thereof providing an upper cover.




The preceding lift screen further has the upright post at a periphery thereof provides a plurality of guiding catch grooves and each one of the guiding catch grooves has a top engaging hole and a lower post engaging hole; and an elongated trunking plate at both ends thereof provides a retaining pin and an arched retaining pin respectively to engage with the top fitting hole and the lower post fitting hole respectively.




The preceding lift screen further has the arched retaining pin providing a first, a second and a third plane; the first plane is a arched plane with a retaining pin, the second and the third planes are flat and perpendicular to each other; and the third plane may provide a joining hinge part to fit with a recess at an end of the trunking plate.




As the foregoing, a main feature of the present invention resides in that a light and compact lift screen with multiple functions is offered so that the lift screen can be flexibly adjusted according to different needs of the user. In addition, the present invention can be set up to constitute different arrangements for different purposes such as a personal office desk, a private conference room partition, a partition for a project research room or a test room so that the present invention can give the user a more flexible use and a more private meeting space with an environment for convenient communication need.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 2 and 3

, a lift screen according to the present invention comprises at least an upright post


10


, a lift mechanism


20


and a partition board


30


. The upright post further comprises a hollow body


12


and the lift mechanism


20


is disposed in the hollow body


12


.




Referring to

FIG. 3

again, the partition board


30


provides at least a slide plate


31


and the slide plate


31


at the lower side thereof connects with a threaded support bush


24


of the lift mechanism


20


. The threaded support bush


24


engages with a screw rod


22


so that the slide plate


31


can move upward and downward as soon as the lift mechanism


20


is in operation. The lift mechanism


20


comprises a motor


21


with a shaft thereof connecting with the screw rod


22


and the screw rod


22


at an upper end thereof movably fits with a bearing


23


, which is fixedly attached to the top of the hollow body


12


of the upright post


10


. As soon as the motor


21


starts to run and rotates the screw rod


22


, the threaded support bush


24


may move up and down freely together with the slide plate


31


and the partition board


30


to perform the lift function thereof. Further, the partition board


30


at upper side thereof provides an upper cover


32


as shown in

FIG. 7

to hide a clearance at an inner side of the table part


50


or the upper cover


32


acts as an article stand for the space available for placing article being increased.




Referring to

FIG. 4

, the upright post


10


provides a plurality of vertical guiding catch grooves


11


, which are made from aluminum extrusion or the like for the slide plate


31


with the partition board


30


being possible to slide along one of the guiding catch grooves


11


smoothly without sway as shown in FIG.


2


. The respective guiding catch grooves


11


at the top thereof has a key shaped top fitting hole


111


and at a plurality of square post fitting holes


112


below the top fitting hole


111


for a cylindrical retaining pin and an arched retaining pin


411


attached to an end of a respective elongated trunking plate


40


can be retained on the upright post


10


to pin down the upright post


10


and the upright post


10


can be connected to another upright post


10


firmly via trunking plates


40


. Further, accessories such as a table part


50


, an insert hanging hole string


42


, a pedal and a wire passing flute, and a large sized partition plate or a plurality of partition pieces can be hung at the box hole


112


.




The structure can be used not only for the preceding lift screen but also for the upright post in a conventional screen. Referring to

FIGS. 5 and 6

, top views related to the application of the upright post and the arched retaining pins are illustrated. The slide plate


31


and the retaining pins


41


or the arched retaining pin


411


in conjunction with the partition plate


30


and the trunking plates


40


can be arranged as a horizontal positioning or a vertical positioning such that the lift screen can be assembled fast and flexibly to obtain an optimum effect. The arched retaining pin


411


has a first plane


4111


, a second plane


4112


and a third plane


4113


, wherein, the first plane


4111


is an arched plane with a retaining pin with the second plane


4112


and the third plane


4113


being flat and perpendicular to each other. The third plane


4113


may provide a joint


4114


to fit with an engaging recess


401


in an end of the trunking plate


40


as shown in FIG.


4


.




Besides, an example for using the lift screen of the present invention is illustrated in FIG.


7


. The trunking plate


40


is fastened to the table part


50


and the bottom of the table part


50


at two lateral sides thereof provides a leg


51


respectively so as to form a worktable.




While the invention has been described with reference to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined in the appended claims.
