Description

Drawer style seats {Drawer style seats}

The present invention relates to a retractable grandstand that allows a multi-stage grandstand to be sunk in series by a deceleration motor.

Regarding the retractable grandstand, several prior arts such as Utility Model Registration No. 284971 and No. 288950 have been provided.

These prior arts satisfy the basic functions required as a retractable grandstand, but serious problems are exposed in the appearance and horizontal maintenance and support capacity after entry.

In other words, between each visitor stand, the hanger of the guide piece formed opposite to the side of the leg column constituting the visitor stand and the transverse rollers and the longitudinal rollers constituting the guide means remain connected and appear in a straight line. In operation, severe noise is generated between the guide pieces as well as the friction caused by the surface contact with the leg column, and the guide pieces are thin and weak in strength. In the case of severe wear or deformation of the guide piece, the jamming state cannot be maintained, requiring frequent repairs due to departure.

In addition, the guide piece should secure the clearance for sliding contact, and the vertical roller, which also functions as a pusher when the grandstand is unfolded, has a large clearance due to its weak roller axis, which can not be arranged side by side when it is unfolded. It is unsightly, less stable, and has a higher frictional resistance during inlet and outages, which provides another reason why you cannot expect flexible operation.

In addition, each auditorium is configured by simply connecting the upper part of the support column to the rear of the frame through the bracket. When the load of the grandstand is concentrated on the connection part, the supporting force is weak and the frame deflection occurs. If the frame cannot be leveled due to the deflection of the frame or uneven ground due to the lack of support, it is impossible to adjust the horizontal level. There are many problems, such as making you feel difficult and difficult to watch for a long time.

In order to solve the problems as described above, the present invention enables the appearance of the grandstand to be flexible without noise, and the appearance of the audience can be made flexible. Its purpose is to provide a retractable grandstand that can maintain a stable and upright posture at all times and can prevent the frame from sagging due to its strong supporting force at the time of entry.

In order to achieve the above object, the present invention connects the support of each viewing platform with a guide bar and a linear bush so that the guide is linear, and has a height adjusting roller and a guide bracket for supporting the upper frame on each frame. It is possible to adjust and the support and the frame is characterized in that it is configured to have a strong support force when the insertion is supported by the adjustment bolt of the support piece on the inner surface of the support in addition to the bracket on the back of the frame.
