1, the expandable table according to the first embodiment of the present invention includes a panel module 100 and a frame module 200. [

The panel module 100 includes a base panel 110 and a base panel 110 that are rotatably coupled to one side of the base panel 110 and have an area corresponding to the base panel 110 and are stacked on the base panel 110 And an expansion panel 120 extending in a direction extending in a plane of the base panel 110. [

In the present embodiment, the panel module 100 includes at least one hinge member 130 at one side so as to expand while being rotated by coupling the basic panel 110 and the expansion panel 120, 120 are rotated and rest on the second sub-frame 220 to be described later.

2, the panel module 100 may be provided with a slip prevention function for preventing slippage between the basic panel 110 and the expansion panel 120 on either one of the basic panel 110 and the expansion panel 120. In addition, And a handle groove 121 is formed in a side surface of the extension panel 120 opposite to the rotation axis of the panel module 100.

The frame module 200 includes a first sub-frame 210 for supporting and coupling the basic panel 110, and a second sub-frame 210 coupled to the first sub-frame 210 so as to be extended in a sliding manner in a lateral direction, At least one of the first sub-frame 210 and the second sub-frame 220 may include at least one of a second sub-frame 220 on which the extension panel 120 is mounted and a first sub-frame 210 and a second sub-frame 220, And a support frame 230 supporting the first sub-frame 210 and the second sub-frame 220 at a predetermined height from the ground.

3, the first sub-frame 210 includes two support frames 230 to support the basic panel 110, and the second sub-frame 220 supports another Frame 230 and extends through the rail 240 in the transverse direction with respect to the first sub-frame 210. [

The support frame 230 supports the frame module 200 at a predetermined height on the ground so as to be suitable for the use of the table, and may be formed in various lengths depending on the application.

The auxiliary support frame 250 shown in FIGS. 2 and 3 will be described below.

As the second sub-frame 220 is slid and expanded as described above, when the expansion panel 120 is rotated and unfolded, the area of the entire table is increased, the overall support becomes unstable, a large load is applied to the central portion of the panel module, A load is applied to the rail 240.

At this time, in the embodiment of the present invention, the auxiliary support frame 250 is formed at the center of the panel module 100 in a state in which the expansion panel 120 is unfolded, at the same height as another support frame 240.

More specifically, the auxiliary support frame 250 in the present embodiment is provided in the first sub-frame 210 in a folding manner and can be selectively used when the table is extended.

Further, the auxiliary support frame 250 is formed with a protrusion 251 so as to be longer than the conventional support frame 230. This works as an element that helps expand the frame module 200, and a detailed description will be given later.

In this embodiment, the auxiliary support frame 250 is positioned at a central portion when the table of the present invention is expanded. However, the auxiliary support frame 250 may be applied in various forms and positions.

Hereinafter, the process of extending the frame module 200 will be described.

4 is a perspective view and a cross-sectional view illustrating a configuration in which a second subframe is accommodated in a first subframe of an expandable table according to the first embodiment of the present invention.

As shown in FIGS. 3 and 4A, the second sub-frame 220 is at least partly accommodated in a receiving space formed inside the first sub-frame 210, The sub-frame supporting the panel module 100 is extended so as to extend in the lateral direction.

In this embodiment, the first sub-frame 210 and the second sub-frame 220 are connected with a rail 240 having an extendable length and are extended and extended along the extension of the rail 240 .

More specifically, the rail 240 includes a base rail 241 fixedly coupled to the first sub-frame 210 and a movable rail 242 fixedly coupled to the second sub-frame 220, The sliding extension of the second sub-frame 220 is possible as the movable rail 242 slides on the rail 241.

At this time, the support frame 230 provided in the second sub-frame 220 is not accommodated when the second sub-frame 220 is accommodated in the first sub-frame 210, 210 and the support frame 230 to support the second sub-frame 220 and the panel module 100.

When the first sub-frame 210 and the second sub-frame 220 are coupled through the rails 240, the first sub-frame 210 having an open upper surface is coupled with the moving rail 242 The upper portion of the second sub-frame 220 is connected to the lower portion of the second sub-frame 220 such that the height of the upper portion of the second sub-frame 220 is the same, Frame and the sub-frame.

Also, as shown in FIGS. 3 and 4 (b), a configuration in which the third sub-frame 260 and the fourth sub-frame 270 are directly slid without the rail 240 is also applicable.

The overall configuration of the third sub-frame 260 and the fourth sub-frame 270 is substantially the same as that of the first sub-frame 210 and the second sub-frame 220 described above. The details of the third sub frame 260 and the fourth sub frame 270 are not described because they are the same in configuration of the panel module 100 and the support frame 230 and the auxiliary support frame 250, Only the binding relationship will be described.

The third sub-frame 260 has a generally rectangular parallelepiped shape and forms a groove corresponding to the shape of a cross section of the fourth sub-frame 270 described later.

Further, as shown in Fig. 3, a stopper coupling hole 261, which is opened so that the stopper 271 described later can be engaged, is formed.

Inside the third sub-frame 260, a sliding groove through which the head of the stopper 271 bolt 271b can pass is formed in the longitudinal direction inside the surface on which the stopper coupling hole 261 is formed, Turn off the stopper (271).

The fourth sub-frame 270 is formed in the shape of a long rectangular parallelepiped as a whole and forms a projection in the longitudinal direction. At this time, the fourth sub-frame 270 may include a stopper 271 for preventing the third sub-frame 260 from completely falling off at the time of expansion.

The stopper 271 is composed of a socket 271a inserted in the fourth sub frame 270 and a bolt 272b inserted and fixed in the socket 271a and the fourth sub frame 270 is connected to the support frame 230 And is provided at a position corresponding to the stopper coupling hole 261 on the opposite side to which it is engaged.

Like the combination of the first sub-frame 210 and the second sub-frame 220, the height of each top surface is the same after the third sub-frame 260 and the fourth sub-frame 270 are combined.

Next, the expansion of the panel module 100 will be described.

Fig. 5 is a view showing a configuration of the hinge member of Fig. 1;

1, 2 and 5, the panel module 100 includes a main panel 110 mounted on the first sub-frame 210 and at least one side rotatable with the main panel 110 And an expansion panel 120 that is stacked on top of the basic panel 110 or extended in a direction extending on the surface of the basic panel 110. [

The main panel 110 and the extended panel 120 are coupled to each other through the hinge member 130. The extended panel 120 is rotated about the hinge member 130 to rotate the panel module 100, The whole is unfolded. 5, the hinge member 130 includes a first coupling portion fixedly coupled to the basic panel 110, a second coupling portion fixedly coupled to the expansion panel 120, And a rotation part 133 rotatably coupled to the first and second engagement parts 131 and 132.

More specifically, the hinge member 130 is fixed to the base panel 110 and the extension panel 120 by first and second engaging portions 131 and 132, respectively, Since the rotation part 133 formed with the length d2 which is twice the thickness d1 of the first and second coupling parts 131 and 132 is provided on the side of the extension panel 120 when the expansion panel 120 is folded or unfolded, Is not formed.

The operation state and function of the first embodiment according to the present invention constructed through the above-described configuration are as follows.

6 is a diagram illustrating an expansion process of an extended table according to the first embodiment of the present invention.

As shown in FIG. 6, the expandable table according to the present invention can be very easily expanded compared to the existing technology as the frame module 200 slides and the panel module 100 is unfolded.

At this time, since the panel module 100 transmits the load A to the support frame 230 through the first sub frame 210 and the second sub frame 220, It is difficult to subtract.

Therefore, the auxiliary support frame 250 is formed with the protrusion 251 so that the auxiliary support frame 250 has a relatively longer length than the support frame 230.

First, when the auxiliary support frame 250 is first developed, the load supported by the support frame 230 supporting the second sub-frame 220 is reduced, and the user can easily pull out the second sub-frame 220.

The second subframe 220 to which the rail 240 is applied slides within the first subframe 210 by the rail 240 and the inner side of the third subframe 260 in the case of the fourth subframe 270. [ So as to slide.

The protrusions of the fourth sub-frame 270 help to more organically connect with the third sub-frame 260, and it is possible to prevent the wood from being twisted when it is made of wood.

The stopper 271 of the fourth sub-frame 270 is easily detachable through the stopper coupling hole 261 formed on the third sub-frame 260. The stopper 271 guides the sliding movement along the sliding groove formed in the third sub-frame 260 so that the termination is clogged. The stopper 271 has an effect of preventing detachment of the fourth sub-frame 270 because the end is closed.

This configuration is excellent in terms of maintenance and maintenance since the structure can be simply disassembled by removing only the bolt 271b of the stopper 271 through the stopper coupling hole 261 without disassembling the structure when the product is defective.

In addition, the panel module 100 preferably has a lateral area that is relatively equal to or larger than that of the frame module 200.

When the support frame 230 is coupled with the first sub-frame 210 and the second sub-frame 220 in the same manner as the sliding frame module 200, It is formed symmetrically and has structural stability and aesthetic excellence.

As described above, since the upper portion of the second sub-frame is equal to the upper height of the first sub-frame before and after expansion, the extension panel 120 can be more stably mounted on the second sub-frame 220.

Further, when the table of the present invention is expanded and used, the stability of the table can be improved by reducing the load burden on the subframe through utilization of the auxiliary support frame 250 described above.

In addition, through the structure of the three-part structure of the hinge member 130 described above, the table of the present invention can prevent inconvenience in use without protruding back and forth, and can have an aesthetic excellence.
