Folding device for folding table with built-in cylinder}

The present invention relates to a folding device for a folding table that connects the frame of the folding table and the top plate in a rotatable form, and more specifically, a cylinder for maintaining the rotated or expanded state of the top plate is placed inside the folding device. By being integrally formed, the bottom of the folding table can be kept in a simple state, so there is no deterioration of the aesthetics, and a configuration for storing items such as drawers installed on the bottom of the top plate is designed in various shapes and shapes without interfering with the configuration related to the folding device. Folding device for folding table with an improved cylinder that can be installed as an improved table that improves the aesthetics and functionality of the table and simplifies the configuration of the folding table, thereby reducing manufacturing costs and reducing the process defect rate in the assembly process. It is about.

A conventional folding table has a structure in which the upper plate is coupled to the upper side of the support and the support is connected to the legs. In order to easily stack a plurality of tables, a folding table is disclosed that allows the upper plate to be folded to stand vertically.

As an example of such a folding table, Korean Patent Registration No. 10-1120424 (registration date: February 20, 2012) folding table includes an upper plate, an upper frame supporting a lower portion of the upper plate, and a rotating means at a lower portion of the upper frame. In the folding table comprising a lower frame coupled to, and an intermittent means for controlling the rotation of the upper plate,

The intermittent means includes a lever part provided on the upper frame and an intermittent plate fixed to an upper portion of the lower frame, and the intermittent plate is formed in a disc shape of a predetermined thickness, and the upper plate is horizontally positioned on an outer circumferential surface. A horizontal locking groove for holding the top plate and a vertical locking groove for maintaining the upper plate in a vertical state are formed at predetermined intervals, and the lever part is selectively fitted into the horizontal locking groove and the vertical locking groove of the intermittent plate. The locking protrusion comprises an intermittent block formed on one side and an elastic member interposed in the mounting protrusion formed on the lower surface of the other side of the intermittent block, and the locking protrusion has a flat bottom surface, and the upper surface connected to the bottom surface has a predetermined curvature. It is characterized in that it is provided in the shape of a rounded surface rounded to have a radius.

In particular, among the above configurations, as a configuration for rotating the top plate, the unfolded or folded state of the top plate is maintained through a complex configuration consisting of organically connected components such as a lever and a handle, a lever shaft, a connection bracket, and an intermittent plate. There are features.

However, as described above, it is difficult to assemble a structure consisting of a lever and a handle for rotation and control of the upper plate, a lever shaft, a connection bracket, and an intermittent plate, and all are made of metal, so that they are easily injured due to careless handling of the operator during assembly production. There is a problem that the defect rate of work increases due to the difficulty of over and assembly work.

In addition, there is a problem in that the shape and shape of a drawer or the like for storing items formed under the upper plate are limited by assembling each component for fixing the movement and the moved state of the upper plate.
