1 to 9, a desk 10 according to an embodiment of the present invention includes a top plate 20, a frame 30, and legs 40.

The upper plate 20 is formed in a flat plate shape, and can be applied in various shapes such as a circular or polygonal shape on a plane.

The frame 30 serves to support the upper plate 20 from the lower side and the legs 40 serve to support the frame 30 against the floor.

In particular, the legs 40 are connected to the frame 30 in a variety of ways, and are not limited to the number.

For convenience, four legs 40 are shown.

In addition, the desk 10 according to the present invention includes a cloaking device 100 provided between neighboring legs 40 on the front side.

The screening apparatus 100 plays a role of adjusting the opening degree of the front side of the desk 10 according to the purpose or use state of a user (seated person) using the desk 10.

The shielding device 100 includes a post-beam 110, a roll-beam 120, a shielding film 130, and a stopping portion 200.

Post beam 110 is connected to frame 30 or to neighboring legs 40. Thus, the post beam 110 is disposed side by side with respect to the frame 30.

By way of example, the post beam 110 is assembled by axially fitting the clip 114, and the clip 114 is resiliently coupled to the frame 30. Of course, the clip 114 can be deformed into various shapes.

In addition, the post beam 110 forms an opening 112 on the circumferential surface along the axial direction. The opening 112 is formed in a roll shape and serves to guide the withdrawal of the curtain 130 provided inside the post beam 110. At this time, the opening 112 may be formed variously.

Of course, the post beam 110 may be applied in various shapes and materials.

In addition, the roll beam 120 is disposed inside the post beam 110. That is, the roll beam 120 is provided inside the post beam 110 while being disposed in parallel with the post beam 110 in the axial direction.

At this time, the roll beam 120 may be rotatably provided with respect to the post beam 110 in various manners. For example, the roll beam 120 may be rotated circumferentially about the post beam 110 with a ball bearing on its circumferential surface, or alternatively, a sleeve 212 may be inserted axially into the roll beam 120, The cap member 220 is rotatably connected to the cap member 220 so that the roll beam 120 can be rotatably installed with respect to the sleeve 212.

Of course, the diameter and the material of the roll beam 120 are not limited, and two sleeves 212 may be provided on both sides of the roll beam 120, respectively.

The shielding film 130 is wound around the roll beam 120 and adjusted in height relative to the floor according to the area exposed to the lower side of the post beam 110 through the opening 112. The degree of covering the front side of the desk 10 is set .

At this time, the curtain 130 is made of a flexible material so as to be wound around the roll beam 120. Of course, the shape of the screening film 130 can be variously applied.

In addition, the curtain 130 can be automatically wound on the roll beam 120. To this end, the sleeve 212 has a torsion spring 214 on its circumferential surface. The torsion spring 214 is connected to the roll member 120 on one side and to the closing member 210 on the other side to prevent rotation. Therefore, when the curtain 130 is pulled and unrolled by the roll beam 120, the roll 130 is wound on the roll beam 120 when the external force is removed, and can return to the initial state.

In particular, due to the arbitrary rotation of the roll beam 120, the curtain 130 may be excessively unwound from the roll beam 120 or may be wound too much on the roll beam 120.

Thus, the shielding film 130 is held by the stopping portion 200 as long as it is drawn outward (downward) of the post beam 110.

Here, the stopping portion 200 includes a closing member 210, a cap member 220, and a pressing operation portion 230.

The closing member 210 is provided inside the post beam 110 so as to be fixed to one side or both side edges of the roll beam 120 in the axial direction. That is, the closing member 210 is disposed on one side or both sides in the axial direction of the roll beam 120, and is installed to prevent rotation in the circumferential direction. At this time, the closing member 210 is restrained and prevented from being rotated by the roll beam 120 in various ways.

For convenience, the finishing members 210 are respectively disposed on both sides in the axial direction of the roll beam 120. Of course, the closure member 210 is applicable in a variety of shapes and materials.

In particular, the sleeve 212 is provided to extend outward from the closing member 210, and both sides of the sleeve 212 are installed so as to extend outward from each of the closing members 210 while being axially inserted into the roll beam 120. At this time, the sleeve 212 is rotatably shaft-inserted into the circumferential rotation-prevented closing member 210.

Further, the cap member 220 is arranged to receive the corresponding closing member 210 therein. The cap members 220 are disposed on both sides in the axial direction of the post beam 110 so as to correspond one-to-one with the closure members 210 provided on both sides of the roll beam 120, respectively.

In addition, the cap member 220 may be constrained to be fixed to the post beam 110. The cap member 220 can be coupled to the post beam 110 in a variety of ways. Of course, the cap member 220 may be fixedly attached to the adjacent legs 40. The cap member 220 is applicable in various shapes and various materials.

In particular, the cap member 220 forms a receiving groove 222 of a polygonal or elliptical shape that is not circular inside. The sleeve 212 is formed in the same shape as the receiving groove 222 and is fitted into the receiving groove 222.

The sleeve 212 is inserted into the receiving groove 222 of the corresponding cap member 220 to support the roll beam 120 and is prevented from rotating in the circumferential direction together with the cap member 220. Of course, the receiving groove 222 may be deformed into various shapes.

Meanwhile, the pressing operation unit 230 functions to prevent the natural rotation of the roll beam 120 by pressing the peripheral surface of the closing member 210 while being supported by the cap member 220.

The pressing operation portion 230 includes a communication hole portion 231, an inclined surface portion 232, a pressing pad 233, and a pressing guide block 235.

The communication hole portion 231 is formed on a part of the circumferential surface of the cap member 220 so as to coincide with the peripheral surface of the closure member 210. At this time, the communication hole portion 231 is formed on the lower circumferential surface of the cap member 220 that has been installed. Of course, the shape and size of the communication hole portion 231 can be variously applied.

The inclined surface portion 232 is protruded from the inner surface of the cap member 220 so as to correspond to one side edge of the communicating hole portion 231 or both the innermost edges of the communicating hole portion 231 along the rotation direction of the roll beam 120. At this time, the inclined surface portion 232 is formed to be upwardly inclined as it is away from the communication hole portion 231. [ For the sake of convenience, the inclined surface portion 232 is formed to protrude from the inner surface of the cap member 220 corresponding to one side edge of the communication hole portion 231. Of course, the inclination of the inclined surface portion 232 is not limited.

Further, the pressure pad 233 is mounted inside the cap member 220 through the communication hole portion 231. [ At this time, the pressing pad 233 may be formed to have a trajectory of the same curvature as that of the cap member 220. Of course, the pressing pad 233 can be applied in various shapes and various materials.

The pressing pad 233 is moved along the peripheral surface of the cap member 220. The pressing pad 233 may include a handle 234 projecting through the communication hole 231 to receive an external force for movement.

The handle 234 can be deformed into various shapes. In particular, the communication hole portion 231 is formed on the circumferential surface of the cap member 220 for exposing the handle 234, and the cap member 220 (not shown) is provided to limit the movement locus of the handle 234 connected to the pressing pad 233. [ As shown in Fig.

As described above, the communication hole portion 231 is formed on the lower circumferential surface of the cap member 220.

The pressing pad 233 is retained in the cap member 220 through the communication hole 231 so that the pressing pad 233 is spaced apart from the closing member 210 due to its own weight when the external force is not applied. Thus, the closing member 210 and the roll beam 120 are allowed to rotate in the circumferential direction, so that the curling film 130 can be unwound or wound.

The pressing guide block 235 protrudes from one side or both side edges of the pressing pad 233 in the moving direction so that the pressing pad 233 is moved along the slanted surface portion 232 when the pressing pad 233 is moved, So as to pressurize the peripheral surface of the member 210.

That is, the pressurizing guide block 235 is moved along the inclined surface portion 232 along the arc locus, and is moved to the side of the closing member 210 to press the peripheral surface of the closing member 210.

Thus, the closing member 210 is prevented from rotating in the circumferential direction by the urging of the pressure-guiding block 235 supported by the inclined surface portion 232. [

Of course, the pressure-guiding block 235 can be deformed into various shapes.

At this time, slippage may occur between the pressing guide block 235 and the inclined surface portion 232, and between the pressing pad 233 and the closing member 210 in close contact with each other. Thereby, the roll beam 120 can be arbitrarily rotated in the circumferential direction.

In order to prevent this, the pressing operation portion 230 may further include a first concave-convex portion 236 and a second concave-convex portion 237.

The first concave-convex portion 236 is formed on the peripheral surface of the closing member 210 and the second concave-convex portion 237 is formed on the surface of the pressing pad 233 on the side of the closing member 210 side.

When the pressure inducing block 235 is moved along the inclined surface portion 232 by an external force and the pressure pad 233 is moved toward the closing member 210 side, the first concave / convex portion 236 and the second concave / 237) are male and female.

Thus, the pressure induction block 235 and the slope portion 232 are prevented from slipping on the contact surface, and the press pad 233 and the closing member 210 are prevented from slipping on the contact surface.

The second concavo-convex portion 237 may be formed at various positions of the pressing pad 233 and may be formed on the pressing pad 233 so as to move eccentrically when the pressing pad 233 moves along the arc locus.

Meanwhile, since the curtain 130 is made of a flexible material, the curtain 130 can be pulled out from the roll beam 120 and then fixed to the legs 40. This is to prevent fluttering of the screening film 130.

Thus, the fixing portion 300 is provided.

Here, the fixation portion 300 includes an edge member 310, a bracket 320, and a pocket 330.

The edge member 310 is fixed to the inner side of the edge portion 130, not the edge portion of the edge portion. At this time, the edge members 310 protrude from both sides of the curtain 130. At this time, the edge member 310 is applicable to various hard materials.

The brackets 320 are fixed at a plurality of positions along the axial direction of the legs 40. The height of the shielding film 130 is adjusted so that the bracket 320 is mounted at the corresponding position of the leg 40 coinciding with the edge member 310. Of course, the bracket 320 can be deformed into various shapes, can be applied in various materials, and can be fixedly installed on the corresponding legs 40 in various ways.

In addition, the pockets 330 are provided in the bracket 320 to receive and fix the edge members 310. At this time, the pockets 330 are arranged to be opened to the bottom side so that the edge members 310 are prevented from being arbitrarily detached from the inside of the pockets 330.

In particular, the pockets 330 may be provided with a plurality of directional brackets 320 for compatibility. The mounting direction of the pocket 330 in which the opening side is downwardly disposed is set to be the same as the setting direction of the pockets 330 according to the position where the bracket 320 is installed in the right leg 40 and the left leg 40 from the front side of the desk 10. do.

Of course, the pocket 330 can be deformed into various shapes.

Therefore, after the user (seated person) pulls the curtain 130 in the initial state to the underside of the post beam 110 by a desired length, the pusher 233 is pushed toward the pressure guide block 235 by pushing the handle 234 (Gear) engagement between the first concave-convex portion 236 and the second concave-convex portion 237.

The elastic membrane 130 is prevented from rotating in the winding direction of the roll beam 120 and is not loosened from the roll beam 120 arbitrarily, although the resilient force for returning the torsion spring 214 to the initial position is applied.

The user then mounts the bracket 320 at the corresponding position of the leg 40 corresponding to the edge member 310 and then fixes the edge member 310 to the pocket 330. [
