  In both of the conventional tables described in Patent Documents 1 and 2, one end portion of the auxiliary top plate (table top plate or work table) is connected to the side end portion of the top plate in the table (counter or desk). It is attached to the top or bottom surface so that it can be rotated horizontally, and one end of the auxiliary top plate and the side end of the top plate overlap each other, so the effective area on which the top plate or the top top article can be placed Has a problem of becoming smaller.

  In addition, since a step is formed in the mounting portion between the top plate and the auxiliary top plate, not only the article cannot be placed horizontally across both top plates, but also the movement of the article, desk work, etc. It is difficult to use.

Furthermore, since it is necessary to perform processing for component mounting on the top plate of the table so that the auxiliary top plate can be rotated, the top plate can be shared with other tables that do not require the auxiliary top plate. There is also a problem that it cannot be done.

  The present invention has been made in view of the above problems, and a step is produced between the two top plates by allowing the auxiliary top plate to be independently rotated on the side of the main top plate. It is an object of the present invention to provide a table with an auxiliary top plate that can form a continuous wide top plate surface and does not require any processing for attaching the auxiliary top plate to the main top plate.

According to the present invention, the above problem is solved as follows.
(1) The upper ends of the left and right legs are connected to each other by a horizontal connecting rod to form a support frame. With this support frame, the main top plate is moved laterally from the side edge of the main top plate. At the side of the main top plate, the other end portion of the auxiliary top plate having support legs supported by the floor on the bottom surface of one end portion is supported on the side projecting portion of the support frame. Install so that it can rotate horizontally.

(2) In the above item (1), a support member is provided at the upper end of the leg to support and fix the lateral coupling rod so as to be movable in the left-right direction, and the other end of the auxiliary top plate is provided on the upper surface of the support member. Attach the bottom surface to horizontal rotation

(3) In the above item (2), the support member has a vertically divided structure, and the horizontal connecting rod is fixed from above and below by the fastening means.

(4) In the above item (2) or (3), at least two front and rear horizontal connecting rods are provided so as to be parallel to each other, and a support member is fixed to the side end portions of the front and rear horizontal connecting rods.

(5) In any one of the above items (1) to (4), the cross-sectional shape of the lateral connection rod is a hexagon or an octagon.

(6) In any one of the above items (1) to (5), when the auxiliary top plate is rotated to the main top plate side, the side end surfaces facing each other are brought into contact with or close to each other.

(7) In any one of the above items (1) to (6), when the auxiliary top plate is rotated to the main top plate side, the front end surfaces thereof are made to be continuous with each other laterally.

According to the first aspect of the present invention, the auxiliary top plate can be horizontally rotated around the support frame protruding from the side edge on the side of the main top plate. It is possible to easily align with the top surface of the top plate, and it is possible to prevent a step from occurring between the top plates.
Therefore, when the auxiliary top plate is rotated to the main top plate side and a part of the side end surface is brought into contact with the side end surface of the main top plate, a continuous wide top plate surface is formed, and the work area and articles The mounting area can be enlarged.
Moreover, since the auxiliary top plate can be rotated independently, the rotation range becomes large.
Furthermore, since it is not necessary to perform any processing for attaching the auxiliary top plate to the main top plate, the main top plate can be shared with the top plate of other tables.

According to the second aspect of the present invention, the position of the leg and the support member provided at the upper end of the leg can be adjusted with respect to the side end of the horizontal connecting rod. The rotation center position from the side end can be appropriately changed.
Further, since the load on one end side of the auxiliary top plate is always directly supported by the legs, it can withstand a large load.

  According to the third aspect of the present invention, the fixing work between the support member and the lateral coupling rod can be easily performed with the legs attached, and the legs and the support members can be attached only by loosening the fastening means. The position can be adjusted by easily moving in the left-right direction.

  According to the fourth aspect of the invention, since the mounting strength of the support member is increased, the auxiliary top plate attached thereto is also stably supported.

  According to the invention described in claim 5, since the fixing surfaces of the support member are 6 to 8 surfaces, the mounting strength is further increased.

  According to the invention described in claim 6, since the wide top plate surface by the auxiliary top plate is continuously formed on the side along the side end surface of the main top plate, the usability is improved.
