The present invention relates to a technology in which a table is formed on an armrest of a chair and enables forward and backward movement and rotation of the table when folding or storing the table. In order to perform such a table rotation and forward and backward movement, the rotation apparatus is configured in the present invention. The rotation device consists of a body and an activator. Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram in which a table 3 is formed on one side of a chair 2 having an armrest 1.

2 is a configuration diagram in which tables 4 and 5 are formed on both sides of a chair having armrests. In the case of configuring both tables, at least one table must be opened so that the user can enter and exit, so that at least one table is provided with a rotation device.

3 to 6 is a configuration diagram of the configuration of the rotation device of the present invention configured to facilitate the user to enter and exit the chair by rotating the table. In the present invention, the rotation device is configured as a body and an activator.

3 is a configuration diagram of a body part in the rotation apparatus. Body portion 6 in the present invention is fixed to the armrest of the chair. The body guide portion 7 is formed on the side of the body portion.

4 is a block diagram of an actor in the rotation apparatus. The activator 8 is guided by the body and performs a slider movement. There is also a table associated with the actor. The actor has a front and rear conveying guide groove 9 formed in the longitudinal direction of the actor and a rotating guide groove 10 formed perpendicular to the longitudinal direction.

5 is an embodiment of a rotation device. The rotation device rotates the table and also moves the table back and forth. The rotation apparatus may also be configured to simultaneously perform rotation and forward and backward movement. 5 is an embodiment of a rotation device. Body portion 11 is connected to the armrest of the chair, the forward and backward movement guide groove 12 and the rotation guide groove 14 is formed in the actor, and the operator is the body guide portion 13 is fixed to the body portion ), The slide movement is limited to the path of the guide groove.

6 shows various embodiments of an actor. In addition to the front and rear conveying guide groove 16 in the operator 15 to form a stop groove 17 to be able to fix the body guide portion to the stop groove. In addition, by forming a guide groove on the curved surface to enable forward and backward movement and rotational movement at the same time can guide the body guide portion to a more smooth movement, the guide groove of this shape is defined as a compound transfer guide groove (18). The rotation angle which can be rotated by the rotation guide groove is normally 90 degrees.

7 is an explanatory diagram illustrating a configuration in which a table is attached to the rotation apparatus. This embodiment is a form in which the body is configured inside the actor. The actors 22 and the table 19 are connected to the rotary pin 20. The rotary pin allows the table to rotate about the longitudinal axis of the rotary pin. Guide activator 24 is formed in the activator, guided by the body guide portion 23 of the body portion 21 is to perform the slid movement.
