Description

Table with legs {Collapsible table with legs}

The present invention relates to a table provided with a folding leg, and more particularly to a folding leg configured to support the table, of the fixed support and the legs rotated to maintain the folded and unfolded state It relates to a table provided with a folding leg to be fixed to each other in close contact with each other to prevent the legs to rotate arbitrarily to use or store the table more stably.

In general, a table is used to prepare foods and refreshments, or to learn such as reading.

The table is provided with a table leg to support the table to maintain a constant height, the table leg is divided into a fixed type to maintain the vertical state and folded to be easily stored by reducing the volume during storage.

The table equipped with a folding leg to increase the convenience of storage and use in the above has already introduced products consisting of various configurations, among which Utility Model Registration No. 184730 (name: upper leg fixed structure) was disclosed.

Looking at the fixed structure of the conventional upper leg as shown in FIG. 1, the upper and lower legs 110 and the support wood 120 and the fixing block 130 for supporting the upper leg 110 are pivotally installed in the lower part of the upper plate 100. To install, and the fixed plate 140 to maintain the state when folded and unfolded upper leg 110 is to be installed to be rotated.

However, in the conventional fixed structure of the upper leg 110, when the upper leg 110 is folded, the fixing plate 140 of the fixing block 130 having a height to be fixed by pressing the surface corresponding to the upper leg 110, the upper Since the upper leg 110 needs to be installed at the upper end, a hollow 150 for receiving the upper leg 110 folded under the fixing plate 140 is formed.

Since the air hole 150 does not have an element to support the upper leg 110, the fixed plate 140 is easily damaged by supporting only the horizontally applied force of the upper leg 110 on the spread image of the upper leg 110 with a thin plate formed in a thin plate. There was a problem.

Furthermore, the fixing plate 140 is formed with the protrusion 141, and the support neck 120 is formed with the recess groove 121 to fix the fixing plate 140 so as not to move, but this also spreads the upper leg 110 frequently. When the over-folding operation is performed, the protrusion 141 and the recess groove 121 may be worn out due to repeated loads.

In addition, by receiving the external force and the impact applied in the horizontal direction on the top, the projection 141 and the concave groove 121 is easily damaged, or the deformation is made such that the shape is worn, the projection groove ( 121) was not forced to fit, there was a loose, the most fatal problem that can not support the upper leg (110).

That is, a large hole 150 is formed at the lower portion of the upper leg 110, which can support the upper leg 110, and only the fixing plate 140 of the thin plate is supported, and the protrusion 141 is also detached. The biggest problem is that the ability to support the upper leg 110 is lost due to the problem that the fixing plate 140 is not fixed due to looseness due to breakage or wear of the recessed groove 121.

Therefore, the conventional upper leg fixing structure was a necessary configuration as a limitation that can not only be fixed to the fixed plate by mounting a separate ball stopper, but this leads to an increase in the cost of manufacturing the phase, and the problem of increasing the purchase cost evenly will be.

The present invention has been made in order to solve the above problems, install a fixed support having a suitable thickness that can be rotated at right angles to the rotation direction of the leg installed in a folding table below the table, the fixed support The entire surface is fixed in close contact with the legs so that the legs can be firmly fixed by increasing adhesion, thereby preventing the legs from being unfolded or folded arbitrarily without a separate device. It is to provide a table provided with a folding leg excellent in convenience and robustness to remove unnecessary elements.

The present invention is configured as follows to achieve the above object. That is, the upper plate is made of a plate, the boss protrudes on the lower edge, the bracket is fixed to be spaced apart from the boss of the plate to support the legs rotatably, and rotates between the boss of the upper plate and the bracket with a rotating bolt And a fixed support that is secured to be unfolded and folded and rotatably fixed to the lower surface of the upper plate so as to prevent the leg from being folded after being unfolded.

Here, the legs are characterized in that at least three or more are installed on the lower surface of the upper plate.

In addition, the fixed support is formed with a first and a second fixed surface which is in contact with the first and second contact surface of the leg, the first and the first contact surface and the first fixed surface of the folded state is in close contact with each other, the unfolded state The second contact surface and the second fixed surface of the leg is in close contact with each other, characterized in that to prevent the legs from being arbitrarily folded or unfolded.

In addition, the leg has a rotation hole penetrated at one end to penetrate the rotating bolt, and the fixing groove is formed so that the one end is in close contact with the lower surface and the inner surface of the reinforcing member in a state where the rotating bolt is rotated in use. It is characterized by.

In addition, the bracket is characterized in that the rotating bolt is inserted into the counter boring is formed to stop the head of the rotating bolt to prevent exposure.

In addition, the boss is formed along the longitudinal direction of the both sides of the upper plate lower surface and both ends are joined to the end of the reinforcing member, in cooperation with the reinforcing member is characterized in that it is formed throughout the upper plate lower surface edge.

And, the boss is characterized in that the nut is inserted so that one end of the rotating bolt is fastened.

As described above, according to the present invention, even if the legs supporting the table and the fixing support for supporting the legs are different from each other, even if the legs are to be arbitrarily unfolded, the tightly held supports tightly block the legs to move and store the table. There is an easy effect, such a fixed support has the effect that the first and second fixed surfaces are always in close contact with the first and second contact surfaces of the legs in the folded and unfolded state of the legs to further improve the firmness.

In addition, the fixing groove formed on one end of the leg is effective to accommodate the reinforcing member to hold stably.

In addition, the counter boring formed in the bracket is to prevent the external exposure of the rotating bolt has the effect of improving the design effect of the table.

In addition, by using a rotating bolt, if the effect of improving the robustness of the table and the leg is broken, there is an effect that can be easily replaced with a new leg by loosening only the rotating bolt.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2 to 6, the upper plate 10 and the bracket 20 which is installed on the lower surface of the upper plate 10 to support the food or objects largely, and the bracket 20 as shown in the accompanying drawings And a table 1 including a leg 30 rotatably installed and a fixing support 40 rotatably installed to be firmly fixed in a folded or unfolded state.

The top plate 10 is made of a plate body to put food and refreshments or things such as books, the boss 11 is formed to protrude along the longitudinal direction on both sides of the lower surface of the top plate 10.

In addition, the upper plate 10 is protruded along the longitudinal direction of the reinforcing member 12 on the other side edge where the boss 11 is not installed, and the ends of the reinforcing member 12 are connected to both ends of the boss 11. It is desirable to reinforce the top plate 10 more firmly.

Therefore, the reinforcing member 12 and the boss 11 are formed to protrude throughout the lower edge of the upper plate 10 in cooperation with each other, so that the bracket 20 and the fixed support 40 are installed on the lower surface of the upper plate 10. It can prevent exposure to the outside.

The bracket 20 is installed to be spaced apart from the boss 11 installed on the lower surface of the upper plate 10, and is fixed using the inner side of the reinforcing member 12 or the lower portion of the upper plate 10 and the fixing bolt 33. The inside of the counter boring 21 is inserted into the rotating bolt 22 is installed through the head of the rotating bolt 22 is stopped.

Here, the counter boring 21 communicates with the rotation hole 33 formed at one end of the leg 30 and the nut 13 inserted into the inner surface of the boss 11, and the pivot central axis of the leg 30 is rotated. The rotating bolt 22 is inserted into the counter boring 21 to be fastened to the nut 13 and one end.

In addition, the uppermost portion of the bracket 20 may be formed to be the same as the uppermost height of the folded leg, but by forming the uppermost height of the bracket 20 higher than the uppermost portion of the folded leg 30, the leg 30 is in an unfolded state It is desirable to be able to support the external force applied in the bracket 20 direction.

The leg 30 is interposed between the boss 11 and the bracket 20 of the upper plate 10, so that the rotating bolt 22 installed in the bracket 20 can rotate through the rotating hole 33. Is installed.

In addition, the leg 30 is provided with a first contact surface 31 in close contact with the fixed support 40 and a second contact surface 32 in close contact with the unfolded state.

In addition, one end of the leg 30, that is, the shortest end formed with the rotation hole 33 is formed in a flat surface, and when rotated to stand, the shortest part is in close contact with the lower surface of the upper plate 10 so as to vertically load the upper plate 10. It is possible to support, preferably forming a fixing groove 34 cut in a right angle to form a substantially "b" shape, the fixed groove portion 34 is a reinforcing member 12 when the leg 30 is unfolded In close contact with the lower surface 12a and the inner surface 12b), the vertical load transmitted from the upper plate 10 and the horizontal load transmitted from the side are simultaneously supported.

These legs 30 are provided at least three or more at the lower edge portion of the upper plate 10 to support the table 1, preferably the upper plate 10 is made of a square In this case, it is most preferable that four are installed at the corners of the lower surface.

The fixed support 40 is rotatably installed by the lower surface of the upper plate 10 and the hinge 43 in a position not to interfere with the bracket 20, so as to rotate in a direction perpendicular to the rotational direction of the leg 30. Is installed. In other words, when the leg 30 rotates about the Y axis, the fixed support 40 rotates about the X axis.

In addition, the fixing support 40 is formed to maintain a folded state and an unfolded state by forming the first fixing surface 41 and the second fixing surface 42.

The first and second fixing surfaces 41 and 42 have the first contact surface 31 and the first fixing surface 41 in close contact with each other in the state in which the legs 30 are folded. prevent.

Alternatively, the unfolded leg 30 invades the second contact surface 32 of the leg 30 by the thickness of the fixed support 40 erected by the hinge 43, while the second fixed surface 42 is the second contact surface. (32) and firmly in close contact with each other is to make the leg 30 is completely fixed.

The operation of expanding or folding the legs 30 of the table 1 configured as described above is as follows.

First, as shown in FIG. 4 to FIG. 8, in order to straighten the folded leg 30, the fixed support 40 closely contacted through the first contact surface 31 and the first fixing surface 41 of the leg 30. Rotate the legs (30) in the pull out.

Subsequently, the leg 30 is rotated so that the fixing groove 34 formed at one end of the leg 30 accommodates both the lower surface 12a and the inner surface 12b of the reinforcing member 12.

When the legs 30 are unfolded, three directions of the legs 30 are restrained by the boss 11, the reinforcing member 12, and the brackets 20, and only one direction is opened.

The open one direction is to be fixed in close contact with the second contact surface 32 of the leg 30 by the thickness of the second fixing surface 42 when the fixing support 40 is opened using the hinge 43, By closing the open portion by the thickness of the fixing support 40 will be able to restrain the four directions of the leg (30).

In this way, the state where the leg 30 of the table 1 is extended can be maintained, and when the leg 30 is folded in reverse, it progresses in the reverse order of spreading operation.

As described above, when the first and second contact surfaces 31 and 32 and the first and second fixed surfaces 41 and 42 are firmly adhered to each other, the legs 30 and the fixed support pivoted on the table 1 40) can be completely prevented from rotating arbitrarily unless the user rotates for use and storage.
