Description

Portable screen device equipped with a folding member to be deployed in four directions {4-way-hanging portable screen device}

The present invention relates to a portable screen device, and more particularly, to a portable screen device deployed in four directions provided with a folding member that is deployed in up, down, left and right to improve the portability and usability of the screen device at the same time.

Generally, the screen device is used to project the image projected by the projector. In many cases, the surface of cloth, paper, resin, etc. is coated with excellent light reflecting efficiency. The image needs to be clearly reflected, faithful reproduction of color, high reflectance, uniform and bright from a wide angle, and appropriate directivity are necessary.

Such screens may be of various types depending on the place where they are installed. However, large screens of fixed type are generally used in large places such as theaters, and are manufactured to be folded in relatively narrow places such as lecture rooms or conference rooms. Portable screen devices are being used.

Conventional portable screen devices are constructed by simply hanging a screen, which is a projection screen, on a wall, or constructing a trivet-shaped pedestal, and spreading the screen over the pedestal.

However, when the portable screen device is used on a wall, it is not easy to store it after use, and when moving the installation place, it is inconvenient to nail the screen to hang the screen, and the screen is stored separately. There was a problem that should not be easy to carry.

In order to solve this problem, the portable screen device has been improved, and FIG. 1 is a block diagram showing a conventional improved portable screen device.

As shown in FIG. 1, the conventional portable screen device S includes a cover 3 having fasteners 3a fastened to both sides of the top and a clip-shaped handle 3b fastened to an outer surface thereof; A lower case (4) having a lid insertion hole (4a) in which the cover is recessed at an upper side thereof, and a stopper (4b) fastened to both sides thereof; A screen membrane (5) wound on the inside of the lower case (4) and connected to the cover (3); It consists of a screen frame (6) provided to support the screen film (5) which is vertically moved inside the screen film (5).

Such a conventional portable screen is vertically rolled up to reduce its volume, but there is a problem in that portability is deteriorated because it cannot be reduced horizontally.

Looking at the operation of the portable screen device provided with a folding member to be deployed in four directions according to the present invention made of the above configuration as follows.

As shown in FIG. 2, the portable screen device having a folding member to be deployed in four directions according to the present invention can reduce the size of the screen device 1, thereby facilitating portability.

Here, the action of reducing the size of the screen device 1 will be described. As shown in FIG. 3, the fixed frame 20 upright formed on both sides of the screen film 10 having a flexible property to facilitate deployment and folding. ) And the upper folding arm 31 coupled to one surface of the fixing frame 20 by the upper hinge arm 31 coupled by a plurality of hinges h folded to the upper and lower sides, respectively, so that the upper folding arm 31 is folded. By moving the fixed frame 20 horizontally, the horizontal area of the screen device 1 together with the screen film 10 connected to the fixed frame 20 is reduced.

On the other hand, the lower folding arm 41 is folded to the upper and lower, respectively, the same as the upper folding arm 31, is connected to the fixed frame 20 of the screen film 10 and the screen device (1) The horizontal area is reduced.

In this case, when the upper folded arm 31 is folded downward, the lower folded arm 41 is folded upward to correspond to the upper folded arm 31 so that the upper folded arm 31 and the lower folded arm 41 do not collide with each other and are not folded. In order to prevent this, as shown in FIG. 5 (a) by crossing the upper folded arm 31 through the folding through-hole 43 formed in the upper surface of the lower folded arm 41, Figure 5 (b) The horizontal area of the screen film 10 and the screen device 1 is reduced.

4, the upper surface of the screen film 10 is connected to an end portion of the lower vertical arm 42 formed perpendicular to the lower folding arm 41, and the lower folding arm 41 is folded. By moving the upper surface of the screen film 10 upwardly or downwardly by movement, the vertical area of the screen device 1 together with the screen film 10 is reduced.

In addition, the lower surface of the screen film 10 is connected to the end of the upper vertical arm 32 formed perpendicular to the upper folding arm 31, the screen film 10 by the folding movement of the upper folding arm 31 By moving the lower surface of the up or down, the vertical area of the screen device 1 together with the screen film 10 is reduced.

As a result, the horizontal and vertical movements can be simultaneously acted only by the horizontal movement of the fixed frame 20, so that the installation work becomes convenient, and the size of the screen device 1 can be easily changed due to the horizontal and vertical movements. You can do it.

And, as shown in Figure 6 by rotating the frame extending member 23 provided in the upper and lower portions of the fixed frame 20 to be the same as the longitudinal direction of the fixed frame 20, the screen device that is developed ( It is formed so as to correspond to the vertical length of 1), and when the screen device (1) is folded by rotating the upright frame extending member 23 at a right angle, the cover receiving portion formed inside the frame extending member ( The upper and lower parts of the screen device 1 are recessed to cover the inside of the 24.

On the other hand, when the screen film 10 is deployed, the edge connecting means 25 formed on one surface of the cover receiving portion 24 is provided with a ring strap (not shown) or nonwoven fabric (not shown) provided on the screen film 10. It is possible to flatten the corners of the developed screen film 10 by connecting to a) or the like.

And, as shown in Figure 7 (a) it is possible to rotate the mounting fixing members 52 provided on both sides of the mounting member 50 to squeeze the screen device (1) deployed horizontally, As shown in FIG. 7B, the mounting fixing member 52 is vertically rotated to cover both sides of the folded screen device 1 to cover the outer surface to improve portability.

In addition, as shown in FIG. 8, the screen device 1 may be installed or mounted on an irregular surface by the support coupling portion 53 formed at the lower portion of the mounting member 50.

As shown in FIG. 9, the audio unit 60 embedded in the fixed frame 20 outputs the audio input from the projector 2 to the screen device 1 so that the image and sound can be simultaneously felt. This can improve the viewing experience.

In addition, as shown in Figure 10 by driving the motor (M) provided in the fixed frame 20 to rotate the chain pulley 72 connected to the motor (M), mounted on the chain pulley 72 The blockchain 71 can be wound or unrolled.

Here, when the block chain 71 is released as shown in the enlarged portion of FIG. 10, the block chain 71 acts to push and push a plurality of block chains 71, and the block chain 71. In the case of winding), a plurality of block chains 71 are spaced in a flexible manner to be wound around the chain pulley 72.

On the other hand, when the block chain 71 is released, the block chain 71 is caused to contact the inner surface of the power guide piece (S) by bending the block chain 71 upward by the rotation radius of the chain pulley 72, The 71 can be applied horizontally without bending.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
