Conventional bleachers of this type are equipped with rollers at the bottom.
By arranging the bases of each tier with pillars erected on the top, and arranging them outwards in proportion to the height of the movable floor tables with chairs for each tier, all the movable floor bases are mutually connected. It is connected to and is formed so that it can be moved by expansion and contraction in the front and rear directions. When these seats are in use, they are pulled out one after another starting with the lowest movable platform at the front, and the entire structure is extended into a dais-like structure, thereby allowing a large number of spectators to sit on the chairs on each movable platform. When not in use, contrary to the above, the seats can be stored in the storage recess at the rear by shrinking and storing them sequentially from the frontmost movable platform to the highest movable platform. However, in this case, the chairs on each stage of the movable bed were configured to be folded onto the movable bed.

This idea solves the problems of the conventional technology, and by making it possible to detachably attach a memo stand to the head of each chair's support, the memo stand can be attached when in use, and can be attached when not in use. To provide a memo stand built-in device for an extendable staircase-shaped bleacher chair, which allows the chair to be stored in a state where the chair is removed. The feature of this invention is that the seats for the bleachers are arranged so that they can be raised and lowered on a movable platform that is connected to each other so as to increase in height and expand and contract in the front and rear directions. A storage shaft is inserted into the outer abdomen near the tip of the arm base tube with a hook metal fitting attached to the base end, and a stopper plate is attached to the storage shaft near the tip of the arm base tube with a collar attached to the hook metal fitting. The end portion is fixed to the arm base tube with the intervention of a collar so as to form a hollow space, and the storage shaft is rotatable within a predetermined angle range that does not rotate the bearing plate once. This is due to the shaft fitting.

のメモ台組込装置に構成されている。 An L-shaped bearing plate 12 is fitted into the storage shaft 5 at the hollow K position formed between the arm base tube 3 and the stopper plate 8 under conditions to be described later. As clearly shown in FIG. 5, the bearing plate 12 is provided with a mounting hole 12a near one end of the vertical plate portion 12e, and can be engaged with a portion of the collar 9 of the stopper plate 8 on the other end side edge. In addition, a round bar part 12f is welded to a horizontal plate part 12d arranged at right angles to the vertical plate part 12e, and bearing holes 12b are provided at both ends of the horizontal plate part 12d. . The bearing plate 12 is pivotally fitted into the storage shaft 5 through its mounting hole 12a as shown in FIG. 1. in this case,
The vertical plate portion 12e is shaft-fitted onto the round bar portion 12f. Since the round bar part 12f of the bearing plate 12 is thicker than the hollow part K at this position, unless the round bar part 12f is rotated clockwise around the storage shaft 5 via the front of the storage 5, the upper side It is fitted in such a way that it is impossible to move up. When the bearing plate 12 is rotated clockwise around the storage shaft 5, the horizontal plate portion 12d adjacent to the round bar portion 12f
Since the bearing plate 12 contacts the upper edge of the stopper plate 8, the bearing plate 12 is rotatably fitted to the upper edge of the stopper plate 8 up to the time of this contact, so that the bearing plate 12 can rotate freely within a predetermined angle range that does not rotate once, and as a whole, one set of telescopic stairs is formed. It is configured as a memo stand built-in device for the shape of the bleachers.

柱1の頭部に着脱自在に装着することができる。 When using the bleachers A in an environment that requires a memo stand M, first pull out each movable platform E sequentially from the frontmost side onto the floor surface G in front of it so that the entire structure is tiered. After it is extended, attach the base side hook fitting 4 of the arm base tube 3 to the head of the column 1 of the chair F on the movable floor table 4 of each stage, and attach the pin 6 inserted in the upper part to the front part of the head of the column 1. The recess 4b on the lower end side is engaged with the pin 2b of the socket 2, and in this state, the locking member 7 on the lower end side of the front surface is inserted into the socket 2. By elastically locking onto the bottom hook piece 2c of 2, the memo stand incorporating device with the memo stand M can be detachably attached to the head of the chair support 1.

して使用することができる。 Next time you need to use memo stand M,
Hold the memo board 15 in the state shown in the figure, centering on the storage shaft 5.
When the bearing plate 12 is rotated clockwise when viewed from the seating side, the bearing plate 12, which had been in a hanging state until then, is pivoted so that it can freely rotate within a predetermined angle range that does not rotate once. From the previous hanging state, it will stand up in a handstand shape moving forward. At that time, since the memo base plate 13 is attached to the bearing plate 12 in a hinge shape, the memo base plate 13 and the memo base plate 15 can be held upside down using the pins 14 inserted through the collars 13a on both sides as fulcrums. The memo board 15 descends from the vertical position to the horizontal position on the arm base tube 3, and the horizontal plate part 12d comes into contact with the upper edge of the stopper plate 8, so that the memo board 15 is maintained in a stable horizontal state. Therefore, it can be used as a memo stand M.
また、このメモ台Mの使用が終了して観覧席A

る。 Also, when the use of this memo stand M is finished,
To store the memo board 15, again move it away from the top of the arm base tube 3 and stand it up vertically.
Then, by returning the memo board 15 and the bearing plate 12 to the hanging position via the path opposite to the above, the memo stand M can be removed by removing the hook 4 from the chair support 1. Each chair F from which the memo stand M has been removed is smoothly folded onto its movable floor base E, thereby making it possible to easily and reliably store the bleachers A in the storage recess at the rear.

This idea is based on a hook that is fixed to the head of each chair's column in bleacher seats that are arranged in a movable platform that expands and contracts in the front and rear directions and that are connected to each other so as to increase in height. A storage shaft is inserted into the outer abdomen near the tip of the arm base tube with a metal fitting attached to the base end, and a collar is attached to the storage shaft at the end of the stopper plate near the tip of the arm base tube with a collar attached closer to the hook metal fitting. It is fixed to the arm base tube so as to form a hollow space between the arm and the base tube, and the storage shaft in the hollow position is rotatable within a predetermined angle range that does not rotate the bearing plate once. It is characterized by being shaft-fitted. Therefore, since a memo stand can be detachably attached to the head of each chair's support, the memo stand can be used to expand the range of multi-purpose use of the entire bleachers, not just for viewing. This has the effect of greatly expanding the economic benefits of this type of seating.
