Description

Single - body type table {A table}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table which is applied to a food service station, resting place and cafeteria, and more particularly, So that it is possible to minimize the damage to the floor surface, and more particularly, to a stand-integrated type table capable of securing a supporting force against a seat and realizing stability.

Typically, the dining room or rest area has tables and chairs that allow the user to sample food or rest on objects.

Since such tables and chairs are usually separated from each other, there has been a problem in that after the use of the chair, the problem of clearing the chair and occupying the passage of people are not utilized efficiently.

Accordingly, in recent years, a chair integrated type table has been proposed and used in which a table and a chair are integrally combined to increase the space utilization efficiency.

In Korean Patent Registration No. 10-1104787 (titled table formed integrally with a chair), as described in the publication, in a conventional table, one end of a pair of connection frames is rotatable with a frame under the table And the other end portion of the chair is rotatably connected to the lower portion of the chair, and the chair and the chair are integrally formed by a pneumatic cylinder having a certain elasticity.

Thus, the chair can be automatically moved and fixed accurately inside or outside the table.

On the other hand, in Korean Patent Registration No. 10-1467702 (name: a folding chair integrated type table provided with a connection support), as described in the publication, a table top plate of a rectangular shape, And a side support member for supporting the table top plate, the side support members being connected to both ends of the support frame, A chair frame having a pair of support frames, a table leg coupled to an edge of the horizontal frame and coupled to an intermediate portion of the table leg and a lower end portion of the support frame, and a foldable chair assembly And is assembled and installed in a chair.

Accordingly, the chair assembly rotates to the inside of the table to adjust its position.

In Korean Patent Registration No. 10-1476547 (name: foldable chair integrated type table), as described in the publication, a rectangular top plate, a pair of opposed long side frames and a pair of short side frames, A rectangular horizontal frame for supporting a table top plate, two reinforcing supports to which both ends are coupled at an inner side of the pair of long side frames at positions spaced apart in parallel from each of the short side frames, a horizontal part and a downwardly bent part, A vertical part at each corner of the horizontal frame, a shoulder part, and a wing part, the horizontal part being coupled to at least one of the two reinforcing support rods, the foldable chair assembly being foldably foldably assembled in the downward- Wherein the foldable chair assembly is disposed in the vertical portion on the inner side of the table Wherein the shoulder portion is coupled to an edge of the horizontal frame and the wing portion is curved horizontally at the shoulder portion.

Accordingly, the chair assembly rotates to the inside of the table to adjust its position.

However, in the above-described conventional tables, a conventional chair having a chair leg and a seat plate formed integrally therewith is rotatably coupled to a support for supporting the table with respect to the floor surface, so that when the chair assembly rotates, There is a problem that the chair legs and the floor surface are damaged, and there is a problem that stability is deteriorated due to the floating of the chair when the chair assembly rotates.

In addition, since there are many portions such as table legs and chair legs that are in contact with the bottom surface, there is a problem that it is inconvenient when performing work such as floor cleaning.

Accordingly, the present applicant has proposed Korean Patent Registration No. 10-1542721 (name: an integrated table without a chair support bar) to solve the problems of the conventional table as described above.

As described in Korean Patent Application No. 10-1542721 proposed by the applicant of the present application, the integrated table without the chair support bar has a structure in which the table top plate is supported so as to be supported at the upper end thereof, A connecting frame having both ends connected to one side of the legs by connecting the legs to one side, and a leg which is coupled to the connecting frame at one end and is seated by the user at the other end And a stationary strut having a rotation fixing part for rotatably and axially coupling one end of the counterbore strut, wherein the integrated table is not provided with a chair support bar adapted to support the table top plate coupled to the upper surface thereof against the floor surface; Wherein the leg support is adapted to support the semicircular ring body while having a semicircular shape of the semicircular ring body with respect to a load applied from an upper portion of the leg support by being combined with the semicircular ring body in a vertically symmetrical structure; The connecting frame is configured such that its ends are fixed to connecting pieces for connecting the inner surfaces of the leg supports disposed at positions facing each other.

In other words, as the chair does not have a chair leg and the chair does not have a portion to contact with the floor surface, the chair can be folded and joined together. As a result, contact such as friction with the floor during rotation of the crutch does not occur, In particular, since the left and right coupling legs are connected to the fixing legs connected to the connecting frame connecting the leg supports, the leg support does not flow during rotation, thereby realizing stability.
