Abstract

The present invention is to provide an elevated screen which can be a simple screen or combined with a desk or a table. The elevated screen includes a screen base which sets a inner space in the center, and there is a elevating device in the inner space, and a rotating shaft of the elevating device is set at an outside surface of the screen base to be operated by users, and a bottom of the spacing board is connected to the elevating device in the inner space to be driven up and down by the elevating device, and a top of the spacing board forms a cover, wherein, the inner space of the screen base has various type to match the shape of the spacing board.

Claims

1. An extendable partition screen comprising:

a) an elongated planar base oriented in a vertical direction, the base bounding an inner space with an upper facing opening;

b) upper and lower elongated, spaced apart, transverse rods rotatably located in the inner space;

c) two spaced apart slide assemblies located within the inner space, each slide assembly including;

a transmission belt extending around and driven by rotation of the upper and lower transverse rods; and

a bearer extending from the drive belt, the bearer slidably mounted between spaced apart plates; and

,

d) a spacing board extending substantially across an entire width of the elongated base, the spacing board mounted on the bearers of the slide assemblies whereby rotation of one of the elongated transverse rods moves the spacing board between a retracted position wherein the spacing board is located substantially entirely within the inner space, and an extended position in which the spacing board extends from the base through the upper facing opening.

2. The extendable partition screen of claim 1 further comprising a drive mechanism connected to the lower transverse rod.

3. The extendable partition screen of claim 2 wherein the drive mechanism comprises a manual crank located exteriorly of the base.

4. The extendable partition screen of claim 1 wherein the bearers each have a U-shaped configuration.

5. The extendable partition screen of claim 1 further comprising an upper cover attached to the partition screen so as to cover the upper facing opening when the screen partition is in the retracted position.

6. The extendable partition screen of claim 1 wherein the drive mechanism comprises an electric motor located within the inner space.
