FIELD OF INVENTION [0001] The present disclosure relates to a screen device, and in particular, relates to a screen device capable of combining screens having characteristics of light transmission, opacity, ventilation, or non-ventilation onto a mesh structure.

BACKGROUND OF INVENTION [0002] At home or in the office, in order to achieve the privacy effect of shading or sheltering, a screen device may be disposed onto windows and doors in many buildings without affecting ventilation. However, only one of the opaque screen device and the ventilated screen device may be selected, thereby causing inconvenience in use. In order to improve the aforementioned problems, R.O.C. patent No. 1312026 discloses a folding screen window, wherein a window frame is provided with two foldable curtain modules. Each of the two foldable curtain modules is provided with a movable frame and a foldable curtain. The foldable curtain of each foldable curtain module respectively has the function of ventilation or opaque shading. Therefore, with the aforementioned structural configuration, the user may pull one of the movable frames according to different demands for ventilation or shading, thereby expanding the foldable curtain in the foldable curtain module. The prior art has two different modes of usese of ventilation and shading in the same window frame.

[0003] However, the above prior art can achieve two different functions of ventilation and shading in the same window frame, but still has the following disadvantages.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS [0021] Referring to FIGs. 1 and 2, a screen device according to a first preferred embodiment of the present disclosure is illustrated. The screen device includes a fixing element 1, a pull rod 2, and a mesh structure 3, wherein the fixing element 1 is configured to fix on an inner edge 42 of an outer frame 4. The fixing element 1 is one of a frame and a plate. In the embodiment, the fixing element 1 is a frame. The pull rod 2 is configured to dispose in an opening 41 enclosed by the outer frame 4 and slide therein. The mesh structure 3 is disposed between the fixing element 1 and the pull rod 2. During the sliding process, the pull rod 2 can pull the mesh structure 3 to expand of fold, thereby opening or closing the opening 41 of the outer frame 4. The outer frame 4 is one of a frame of a window or a door and a frame of the screen device.

[0022] Referring to FIGs. 3 and 4, the mesh structure 3 includes at least one first screen 31 and at least one second screen 32. The mesh structure 3 is formed by connecting the first screen 31 with the second screen 32 in series from up to down. In the other embodiment, the first screen 31 is connected with the second screen 32 from left to right, and the disclosure is not limited to the embodiment. In the mesh structure 3, at least one overlapping portion 33 formed between the first screen 31 and the second screen 32, and the first screen 31 and the second screen 32 are connected in series. In the embodiment, a plurality of through holes 311,321 are disposed through the first screen 31 and the second screen 32 and located at the overlapping portion 33. The flexible element 34 passes through the through holes 311, 321. By the arrangement of the through holes 311, 321, the process of connecting the flexible element 34 to the first screen 31 and the second screen 32 can be simple and quick. In the embodiment, the fist screen 31 is one of a transparent film, a light-colored paper, and a light transmissive foldable gauze, which is formed by tightly interwovn and unventilated threads (e.g. fibers or wires). The second screen 32 is one of a non-woven fabric, a plastic, a composite material, a dark paper, a non-transmissive foldable gauze, which is formed by tightly interwoven and unventilated threads (e.g. fibers or wires), and a folded cloth. The mesh structure 3 further includes at least one wire 35. The wire 35 passes through the mesh structure 3 to increase the disassembling resistance of the mesh structure 3, and the smoothness of operation when the mesh structure 3 is pulled by using the pull rod 2. However, the winding method of the wire 35 includes various paths, which are known knowledge, are not the focus of the present disclosure, and are not redundantly described.

[0023] Referring to FIGs. 3 and 4, the flexible element 34 may be replaced by the wire 35. The path of the wire 35 may pass through the through holes 311, 321 disposed on the first screen 31 and the second screen 32. The first screen 31 and the second screen 32 are connected in series by using the wire 35, so that the screen device in this embodiment does not have the problem of the increased number of components caused by the disposition of the flexible element 35. In this embodiment, only one set of wire 35 is required to provide the mesh structure 3 with sufficient anti- disassembling capability, thereby improving the problems caused by the configuration of multiple sets of wires, such as complicated installation and maintenance difficulty. Furthermore, the first screen 31 and the second screen 32 in the embodiment adopt a loosely interwoven foldable gauze and a tightly interwoven foldable gauze, and, therefore, have different functions of ventilation and non-ventilation.

[0024] Referring to FIGs. 1 and 3, when the embodiment is in operation, the mesh structure 3 can be unfolded in the opening 41 of the outer frame 4 by manipulating the pull rod 2. Outdoor sunshine or air enters the room via the first screen 31, and the second screen 32 can be utilized to conceal the interior and achieve privacy. As the described above, in the embodiment, by manipulating the pull rod 2, the desired effect of light transmission and opacity (or ventilation and non-ventilation) can be achieved. Compared with the structure of the two movable frames of the prior art, the embodiment has the substantial benefits of simplifying components and reducing costs. Only one pull rod 2 is arranged in the structure of the embodiment. Regardless of the number of the first screen 31 and/or the second screen 32 connected in series, the mesh structure 3 does not slide down due to the weight of the pull rod 2. In addition, the first screen 31 and the second screen 32 located on the mesh structure 3 can be configured differently according to different needs or occasions in this embodiment. Referring to FIGs. 5 and 6, it is possible to obtain the most effective effects of light transmission, ventilation, shading or even privacy.

[0025] Referring to FIGs. 7 and 8, a screen device according to a second preferred embodiment of the present disclosure is illustrated. The difference from the first preferred embodiment is: the fixing element 1’ is a box, wherein a scroll bar 11 is disposed in the box, and one end of the mesh structure 3’ is wrapped around the scroll bar. The first screen 31' and the second screen 32' of the mesh structure 3' are a flat gauze. An overlapping portion 33’ is formed between the first screen 31’ and the second screen 32’, and overlapping the flexible element 34 in the overlapping portion 33’ is used to connect the first screen 31’ and the second screen 32’ in series. The operation modes of the embodiment and the functions and effects thereof are the same as those of the first preferred embodiment, and thus are not redundantly described.

[0026] The above descriptions are only preferred embodiments of the present invention but are not used to limit the features of the present invention. As long as a reinvention uses technical means or creation principles related to the present invention, the reinvention still falls within the scope of the invention. One skilled in the art, without departing from the spirit and scope of the invention, can make various modifications and variations, so it is reasonable that the range of the scope of the invention is defined by the claims.
