BACKGROUND OF THE INVENTION

1. Field of The Invention:
The present invention relates to an elevated screen, and particularly to an elevated screen with flexibility for being capable for being utilized widely and offering an available open space.

2. Description of Related Art:
Presently, a lot of office buildings are located at the downtown area or any business busy area in a city and it causes the costly rent of an office in these office buildings. In order to utilize a limited space of an office sufficiently and keep the personal privacy without being interfered, the interior spacing design is not possible to be apart from the structure of screen. The way of partition for a screen can be designed differently based on the purpose of use thereof. For instance, the partition can be made for providing a personal working space without any interference or a protective obstacle of team discussion. Alternatively, the screen can be performed as spacing for a large conference or an examination room. Usually, the screen can be classified into two categories based on the way of spacing and one of the two categories is the full height of screen and the other category is the half height of screen. The full height of screen provides a partition erecting upward to the ceiling from the floor. Because the full height of screen is unable for the screen to offer opening and mobility, the full height of screen has been declining due to the mode of job being changed. Instead, the half height of screen emphasize an open space is getting popular.
The half height of screen focuses on no obstacle of visual sense and one type thereof is set up on the floor to be associated with several worktables such that an office can be partitioned into several semi-opened space parts. However, this type of screen is sophisticate to be set up and less flexible in changeability. Another type of half height of screen is mounted on a worktable directly and offers more flexibility while in use. But, the worktable type of screen provides a unique height merely so that it is not satisfactory for the user once the adjustable height is needed.

SUMMARY OF THE INVENTION
An object of the present invention is to provide an elevated screen, which is possible to offer high mobility and great humanization for the adjustable height thereof with excellent flexibility while in use.
In order to achieve the preceding object, the present invention comprises a screen base with an inner space, an elevated device being received in the inner space with a controller thereof at the outer surface on the screen base, and a spacing board with a lower end thereof connecting with the elevated device.

Referring to Figs. 3 and 4, the elevated device 20 has a controller, which is a manual crank rod 21 normally, disposed at the outer surface of screen base 10. The spacing board 30 at the lower end thereof connects with the elevating device 20 so as to be moved upward and downward by the elevating device. Besides, the spacing board 30 at the top end thereof is formed as an upper cover 32 to conceal the clearance resulting from the inner space 12 as shown in Fig. 5 such that an outer surface with good looking appearance can be obtained. Meanwhile, the spacing board 30 at both lateral sides thereof is attached a brush strip 72 respectively to enhance the effect of hiding from view and to obstruct the noise entering the screen. In addition, the size and the configuration of the inner space 12 are variable for being able to accommodate with the spacing board 30 providing a specific size and configuration.
Referring to Figs. 3 and 4 again, the elevating device 20 has an upper transverse rod 22 and a lower transverse rod 23 being fixedly attached to a lateral wall of inner space 12. At least a rotating shaft 24 is fixedly attached to the upper and the lower transverse rod 22, 23 respectively and oppositely. The lower transverse rod 23 at an end thereof joins a manual crank handle 21 such that the lower transverse rod 23 can rotate in accordance with the manual crank handle 21 being turned. Besides, at least a slide assembly 25 is vertically arranged between the upper and the lower transverse rods 22, 23 and it is preferably that two parallel slide assemblies 25, 25 are mounted as shown in Figs. 3 and 4. Each slide assembly 25 comprises two flat plates 251 paralleling disposed near a lateral wall of inner space 12, a guide groove 252 being formed at the opposite inner sides of these two flat plates 251 respectively, and a transmission belt 253 extending vertically through a space confined by these two flat plates 251 and enclosing a respective rotating shaft 24 on the upper and the lower transverse rods 22, 23. In addition, a movable bearer piece 254 is inserted into the guide grooves 252 and fixedly attached to the transmission belt 253 so as to be moved upward and downward. When the crank handle 21 is turned manually to rotate the lower transverse rod 23, the transmission belt 253 is actuated to rotate the upper transverse rod 22 via the rotating shafts 24 such that the bearer 254 can move upward and downward freely with the spacer board 30 supported by the bearer 254. In this way, it is possible for the present invention to perform the effect of elevating screen.
The controller of elevating device 20 can be arranged to provide an electric motor 26 instead of the crank handle in addition to the preceding structure. As shown in Fig. 6, the electric motor 26 connects with the lower transverse rod 23 such that the slide assembly 25 can be driven by the lower transverse rod 23 to perform a relative movement. A start switch 261 for the electric motor 26 is disposed at a proper place on the outer surface of scene base 10 so as to be operated handily by an operator.
In addition, the upper cover 32 can be replaced by a wide upper article stand so as to increase a room for placing articles. Furthermore, two protect rubber plates (not shown) can be arranged at the opening of inner space 12 of base 10 to prevent the inner space 12 from being accumulated by the foreign dirt entering from the clearance between the base 10 and the inner space 12 so as to influence the movement of spacing board 30.
Except the preceding embodiment with regard to the screen base, a worktable can be acted as a base for the elevated screen of present invention and it can be provided with a variety of structures depending on different types of worktables. Figs. 7, 8, and 9 illustrate three embodiments related to the worktable respectively. Referring to Fig. 7, the screen base 10 of elevated screen 1 is a worktable and the inner space with spacing board 30 has a shape of "I". Referring to Fig. 8, the inner space 12 with spacer board 30 on the worktable type of screen base 10 is a shape of "T".
