Field of the Invention The present invention relates to a table conversion chair in which a large number of chairs are arranged in a conference hall or a classroom, and a back plate of a front row is used as a table top. . 2. Description of the Related Art The present applicant has disclosed that a seat portion and a backrest portion (hereinafter simply referred to as a back plate) of a chair are pivotally mounted between both side supports, and the back plate is rotated by approximately 90 ° from below to thereby provide a backrest. A chair having a table surface as a table surface was proposed (Japanese Utility Model Laid-Open No. 5-29462). In this chair, the height of the backboard is the depth when the table is used, and the lower side of the backboard is the front edge of the table. Therefore, it is convenient for the table user sitting in the back row chair to have the table front edge closer, but in this state, the passage in the hall is lost, and it is difficult for people to move. In addition, it is not possible to satisfy the conditions stipulated in the Fire Service Regulations. SUMMARY OF THE INVENTION [0003] The present invention relates to a method of using a table which is close to a rear row user, and which is required to be evacuated to a distant position when a path between front and rear rows of chairs is used. The present invention provides a table conversion chair capable of maintaining a width, and in particular, a table conversion chair which automatically stays at a fixed position by a standing-up operation or a one-touch operation of a seated person so as to be able to cope with an emergency evacuation. It is. [0004] The chair according to the present invention has a back plate pivotally attached to the upper portion of both sides of the support, and the back plate is rotated and fixed substantially horizontally so that the surface of the back plate is in contact with the table surface. And a pair of parallel slide rails fixedly provided on the back surface of the back plate, and a pair of pivotal support members which slidably fit the respective rails and which are pivotally mounted on the inner sides of the both-side posts. A U-shaped rotating base frame formed by connecting and integrating members between each other by a connecting member having a guide groove in a longitudinal direction, and a guide pin projecting from the other end of a swing lever having one end pivotally attached to the back surface of the back plate. Is inserted into the guide groove, and the other end of a tension spring having one end fixed on the connecting member is stretched and locked to the guide pin. It is located on both sides of the connecting member in the stop position. You. With the above arrangement, the back plate table can be moved back and forth, and the tension of the tension spring acts in the opposite direction at each stop position, so that there is no intermediate stop and the both end stop positions are stably maintained. In the process of moving the table, the tension of the tension spring assists in the respective moving directions, so that the table can be reliably operated only with the starting energy. In the drawings, reference numeral 1 denotes a pillar of a chair, and reference numeral 2 denotes a penetrating member, which supports both side columns 4 and 4. Reference numeral 5 denotes an armrest, and reference numeral 6 denotes a flip-up rotary seat. Reference numeral 7 denotes a back plate on which a cushion body 8 is fixed. Reference numeral 9 denotes a surface of the back plate, and 8a denotes a waist rest fixed between the columns. Reference numeral 11 denotes a pair of parallel slide rails fixedly provided on the back surface 10 of the back plate, and each rail is slidably fitted to the rotation support member 13 to form a slider. A pair of rotation support members 1
Reference numeral 3 denotes a rotating base frame 12 having a pivot 14 pivotally supported on the upper portion of the column protruding therefrom and being connected by a connecting member 15 provided at a position off the center of the pivot. When the table conversion chair of the present invention is used as a chair, the back plate 7 is locked to the columns 4, 4 or the penetrating member 2 as shown in FIG. Reference numeral 3 denotes a lock release pedal, and reference numeral 13a denotes a stopper link. 16 is a guide groove formed in a part of the connecting member in the longitudinal direction, and 17 is a tension spring, one end of which is fixed on the connecting member along the guide groove. 2
Reference numeral 0 denotes a swinging lever, one end of which is pivotally attached to the back surface of the table B. A pin 21 protruding from the free end A is fitted into the guide groove 16 and the other end 19 of the tension spring is engaged with the pin 21. . FIG. 2 shows the use state of the table of the above-mentioned table diversion chair. The turning base frame 12 is pivotally mounted 14 on the upper part of the column 4 and cannot be moved. It moves as shown in FIGS. That is, FIG. 4 is a bottom view of the table in use, and is close to a person sitting in the back row chair of the table row at an interval of N (FIG. 1). In this state, the pivot point B of the swing lever 20 is located closer to the occupant than the position A of the pin 21 in the guide groove 16, and the spring 17
Pulling force acts in the direction of arrow S. When the occupant pushes the front edge 9a of the table forward from this state, the state as shown in FIG. 5 is obtained. As the table advances, the point B of the swing lever 20 also moves and moves beyond the connecting member 15 to the opposite side. Moving. Thereafter, the spring force acts to push the table 9 forward through the swing lever, and stops at a position determined by the lever length and the guide groove. Due to the movable range M, the width of the passage for human movement is expanded as M + N as shown in FIG. To return the table position, it is only necessary to push the outer edge 9b of the table against the spring force.
