Description

Folding chair integrated table {TABLE WITH FOLDING-UP TYPE CHAIR}

The present invention relates to a table in which the chair and the table are integrally formed, and more particularly, the connection between the chair and the table is connected by a rotating folding body, and a buffer is further configured at the bottom of the chair to the inside / outside of the table. The present invention relates to a folding chair-integrated table that not only enables the chair to be rotatable and to increase space utilization in a narrow space, but also allows the chair to be automatically folded into the inside of the table.

In general, tables and chairs provided in a dining room or rest room are separated from each other. Especially, in case of installing in a common rest room or dining room, the chairs are not properly rearranged. There is a lot of inconvenience in moving between chairs.

In addition, if you want to clean the floor in a place such as a dining room or rest room where tables and chairs are arranged, there is a problem in that the cleaning work of the cleaning worker is increased by placing the chair on the table top and cleaning the floor.

In addition, when the chair is not pushed into the table after use, it interferes with the mobility of other users, so that a separate worker pushes the chair into the table and arranges it.

In particular, in the case of a common room restaurant, many users are repeatedly gathered at once. At this time, if a person falls into an unorganized chair or falls down, they are dropping the food they are holding. There is a situation.

On the other hand, in view of such a problem, a chair-integrated type table configured to be pulled out from a lower side of the table has been proposed.

In one example, a table with a folding chair having a backrest, which is registered utility model No. 20-0417322, has been conceived, which can be seen by the claims of the registered publication, one or more vertical supports of the table top. A table having a frame, one or more horizontal frames installed between vertical frames, and a backrest on one side of a seat plate supported by a support, is installed on the table formed by a hinge device and a connecting frame to be inserted into and under the upper plate. In the lower surface of the seat plate, a chair support device for rotatably supporting the seat plate is configured.

In addition, the chair support device is configured by installing a cylindrical rotary support on the upper end of the support for supporting the seat plate, forming a shaft hole in which the rotary support is inserted in the center of the support plate constituting the bottom of the seat plate. .

In the case of a table having a folding chair having a backrest, which is configured as described in Korean Utility Model No. 20-0417322, the chair is rotated in / out of the table by a rotating support of the chair support device so that it can be folded in a rest room or a restaurant. When the user does not use the chair, the chair is organized by rotating and pushing the chair directly to the lower part of the top plate, so that the inconvenience of usability and the unfolded chair when the user does not push the chair The problem that another user trips over still remains.

In addition, as the components connecting the chair and the table are connected by welding, the chair and the table cannot be separated. For example, when one of the chair and the table is to be repaired, the entire table including the chair is opened. There is a problem to be moved, there is a problem that the maintenance work is cumbersome, such as each component to be forcibly disconnected to the welding parts connected to each other by welding again to connect the repaired components.
