Description

Folding type table {Folding type table}

The present invention relates to a foldable table which can be folded and unfolded, which can be used outdoors or indoors.

Generally, when eating outdoors or in a tent in an outdoor outing such as a mountain or a field, it is usually inconvenient because the floor is matted on the floor and the food is placed on the matting floor and the waist is bent.

So, there is a table with a chair, but it is made to fit in a car and it is not a size that can be installed in a tent. Inside the tent, you need to sit down and have a meal without the need for a chair, so you need a compact form of table.

Accordingly, a small table such as a patent document 1 (outdoor folding table) in which a meal can be installed in a tent in the form of a meal is invented.

Patent Document 1 discloses a liquid crystal display device comprising first, second, third, and fourth plates arranged in a line; A connecting bracket installed at both ends of the first, second, third and fourth plates and connected to each other through a hinge member so as to be foldable; A fixing bracket installed at both ends of the bottom surface of the first and fourth plates; A support leg rotatably installed on the fixing bracket; And a pair of support bars coupled to the fixing brackets provided on the first and fourth plates so that one ends of the support brackets face each other in a diagonal direction and support the bottom surfaces of the first, A mounting hole is formed in the bottom surface of the free end side; A height adjusting block having a mounting protrusion formed on the mounting hole is formed on a bottom surface of the height adjusting block, and a connection hole is formed on a bottom surface of the height adjusting block.

As described above, Patent Document 1 has the first, second, third, and fourth plates; A hinge member; A connection bracket; A fixing bracket; A support leg; A pair of support bars; And a plurality of height adjustment blocks. Looking at these components in more detail, I point out the problem as follows.

The first, second, third, and fourth plates are provided with a plurality of coupling holes at both ends thereof. The coupling bracket includes coupling protrusions coupled to the coupling holes. So that two connecting brackets adjacent to each other are foldably connected to each other through the hinge member.

The hinge member includes a hinge coupling protrusion protruding from both ends of the connection bracket and a hinge having a pair of coupling holes formed in two adjacent hinge coupling protrusions. The hinge includes first, second, The pair of fastening holes have an appropriate gap in consideration of the thickness of one plate so that they can be folded.

(1) However, in the structures of the first, second, third and fourth plates, the connecting bracket and the hinge member, a connecting bracket is required to fold the first, second, third and fourth plates, The coupling structure of the coupling holes and the coupling protrusions for coupling the first, second, third, and fourth plates is required, and the coupling structure of the hinge coupling protrusion and the coupling hole for coupling the coupling bracket and the hinge, In addition to the hinge, it requires additional components and a coupling structure for folding of the plates 2, 3 and 4, which leads to lowering of assembling workability due to cost increase due to manufacturing cost and complicated coupling structure.

A total of four fixing brackets are provided on the bottom surfaces of the first and fourth plates. The fixing brackets are spaced apart from each other at a predetermined interval and formed with a pair of protrusions. Both ends of the support legs are rotatably coupled to the protrusions. And one end of the support bar is fixed through the restraining pin and restrains the rotation movement of the support bar when necessary.

The supporting leg is formed with a hole to be inserted into the projection of the fixing bracket on both sides of the upper end, and a mounting hole in which the height adjusting block is detachably attached is formed on the bottom surface of the hole so as to further extend the length of the supporting leg, The fixing bracket further includes elastic protrusions which are elastically engaged or disengaged from each other to be elastically held so that the unfolded state is resiliently held, and the fixing bracket further includes a groove into which the elastic protrusions can be elastically inserted.

(2) However, in the structure of the fixing bracket, the supporting leg, and the height adjusting block, the fixing structure of the fixing bracket and the supporting leg requires protrusions and grooves, the structure of the holes and the elastic protrusions in the supporting legs, A mounting hole in the supporting leg and a mounting protrusion in the height adjusting block are required for combining the height adjusting block and the height adjusting block, a plurality of separate height adjusting blocks are required for adjusting the height of the supporting leg, Since the height adjustment block requires a connection hole to connect the upper height adjustment block, the cost increase due to the manufacturing cost and the complex coupling structure deteriorate the assembling workability. In addition, since the height adjustment block connection is simply due to the shape coupling, And the table can be tilted when disengaged during use, and a height adjustment block There is a disadvantage in that it is not possible to adjust the height when the user loses.

The supporting bars are provided across the bottom surfaces of the first, second, third and fourth plates when they are arranged side by side in a row so as to support the unfolded state so that they are not collapsed. A through hole is formed at one end of the fixing bracket to be fixed to one fixing pin of the fixing bracket and a constraining hole is formed at the other side of the fixing bracket so that another fixing pin can be inserted laterally.

Further, the support bar is folded in parallel to the lengths of the first and fourth plates when the support bar is folded, and the pair of support bars are paired with each other so that one ends of the support brackets are opposed to each other diagonally .

Accordingly, the free end of the support bar is rotatable around the through hole, and when the support bar is rotated and the other of the restraint pins is inserted into the restraint hole, the support bar is restrained and restrains rotation of the support bar.

(3) However, in the coupling structure of the constraining hole and the through hole of the support bar and the constraining pin of the fixing bracket, it can be easily disengaged because of the simple shape coupling, and the unfolded table can be folded There is an inconvenience in that it is installed on the bottom of the table and rotates the support bar to support and fold the table.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the technical composition of the present invention will be described in detail with reference to the accompanying drawings.

The folding type table of the present invention comprises an even number of folding plates 10; A plurality of leg frames (20); A pair of folding preventing frames 30; And a height adjuster 40.

The folding plate 10 is an even number, and both ends in the longitudinal direction are opened on both sides of the bottom in the longitudinal direction, and a groove 11 in which the head of the bolt 70 is slidably inserted at both open ends is formed, A hinge groove 12 in which both ends in the longitudinal direction are opened and a hinge 50 is provided is formed on the side surface and a seating groove 13 is formed between the grooves 11 on both sides of the bottom surface.

Here, a plurality of hinges 50 for connecting the folding plates 10 are preferable, and the folding plates 10 are folded in zigzags by the hinges 50. The number of the folding plates 10 is even, There is no.

The leg frame 20 is provided on the bottom surface of the backing plate 10 and is provided with a plurality of brackets 21. The brackets 21 are provided on the upper end of the backing plate 10, Is fastened to the bottom surface of the body by a nut (71), is folded on the bottom surface, enters the seating groove (13) of the bottom surface, and is seated and installed.

In the present invention, the user can arbitrarily change the installation position of the leg frame 20 depending on the situation. That is, when the user loosens the nut 71 and the leg frame 20 is loosened and the head of the bolt 70 is moved from the groove 11 by holding the leg frame 20, 10 so that the leg frame 20 can be moved to an arbitrary position in the longitudinal direction of the uprising plate 10. [

Generally, the leg frames 20 are fixed one by one on the four sides of the table. However, in the case where the number of the folding plates 10 is large, when the leg frame 20 is provided on only the four corners of the table The head of the bolt 70 is inserted into the groove 11 of the folding plate 10 at the central portion or an arbitrary portion of the leg frame 20 in such a case so that the leg frame 20 can not stably support the table. The leg frame 20 is loosely coupled with the bracket 21 and the nut 71 to easily add a plurality of leg frames 20 and then the leg frame 20 is moved to an arbitrary position to tighten the nut 71, The table is supported by the leg frame 20 by means of the four leg frames 20 on the four sides of the folding plate 10 and the plurality of leg frames 20 at the central portion or at arbitrary positions Stable support .

The height adjuster 40 is composed of a support plate 41 having a spiral body and is spirally coupled to the lower end of the leg frame 20 to be elevated and lowered. Accordingly, the height of the table can be adjusted by adjusting the height adjuster 40 to a height suitable for the user, and when the ground plate 10 is used in an outdoor environment where the ground is not flat, the folding plate 10 will be tilted to one side, ), The holding plate 10 can be held horizontally.

In the drawing, the spiral body is shown as a table that is used to sit down while showing the spiral body. However, if the spiral body is long, it can be used as a table that can be used by the user.

Although not shown in the drawings, the height adjusting member 40 may be formed by a telescopic type of a lower frame of a leg frame or a leg frame rather than a supporting plate 41 having a spiral body, It is also preferable to configure it so that it can be used standing up.

The folding preventing frame 30 prevents the opened folding plate 10 from being folded during use. The folding preventing frame 30 has an elastic inlet (not shown) for holding the upper and lower surfaces of the both ends with elasticity by sandwiching both ends in the longitudinal direction of an even- 31).

After the leg frame 20 is vertically folded and folded and the folded sheets 10 are spread out, a table is provided and then both longitudinal ends of the folded sheets 10 are inserted into the elastic inlet 31 of the folding prevention frame 30 When the folding preventing frame 30 is attached to the folding plate 10, the elastic inlet 31 holds the upper and lower portions of both ends of the folding plate 10 in the longitudinal direction with elasticity, so that the expanded folding plate 10 is not folded.

The folding preventing frame 30 is attached to both ends of the expanded folding plate 10 in the longitudinal direction so that the folding preventing frame 30 can be more securely fixed to the length of the folding plate 10 Direction. As shown in the drawing, fasteners 60 having a spiral body are fastened to both ends of the openings of the hinge grooves 12 formed on both sides in the longitudinal direction of the unfolded fastening plate 10, And the body is screwed and fixed to the hinge groove 12.
