Description

All-in-one retractable controller that allows integrated control depending on the usage environment {easy extension control box for drawable seats system}

The present invention relates to an all-in-one retractable controller capable of integrated control depending on the usage environment. In particular, in a retractable bleacher system in which the number of dispenser motors used varies depending on the size of the system, a standardized controller box is provided. This relates to an all-in-one retractable controller capable of integrated control according to the usage environment, allowing easy application to retractable bleacher systems of various sizes by using multiple users and interconnecting them.

Generally, theaters, performance halls, gymnasiums, stadiums or auditoriums are equipped with terraced seating for people to sit and watch plays, movies, performances, sports events, etc., and the terraced seating has a plurality of rows of chairs. It is installed according to the heat.

Among these bleachers, retractable bleachers are configured so that bleacher chairs composed of multiple tiers are sequentially deployed or folded to enable efficient use of space in places such as gymnasiums, auditoriums, various performance halls, halls, event halls, etc.

Figures 1A and 1B are examples of photographs showing a folded state and a drawn-out (unfolded) state of a conventional retractable bleacher system, respectively, and Figure 2 is an example photograph of a dispenser motor installed in a conventional retractable bleacher system. As shown in Figures 1 and 2, the conventional retractable bleachers are folded in series in multiple stages and kept in a stowed state in normal times, but only when in use, the chairs in multiple stages are slid out in series in multiple stages by a drawer motor. It unfolds.

Accordingly, the present applicant proposed as prior art 1 a technology for wirelessly controlling the original function of the bleachers, which can secure space for use in normal times and allow a large number of people to sit when in use, using a smartphone application. Technology 2 was proposed as prior art 2, which prevents safety accidents that may occur when withdrawing or storing retractable bleachers by stopping operation when an obstacle in the path of the retractable bleachers is detected.

In addition, an omnidirectional movable bleacher was proposed as the following prior art 3, allowing the multi-stage folded bleacher body to be easily lifted and easily moved in all directions forward, backward, left, right, and left, thereby increasing transportation convenience. A retractable bleacher chair that is easy to use and store is proposed as prior art 4, which can be deployed and used and can be folded and stored to a minimum volume in normal times, greatly increasing space utilization, convenience of use, and ease of storage. A number of inventions related to retractable bleachers have been applied for and registered for patents.

Figure 3 is an example photo to explain the problem of the controller of the conventional retractable bleacher system. As illustrated in Figure 3, according to the conventional retractable bleacher system, the number of dispenser motors used is different depending on the usage environment or size of the retractable bleacher system, so the retractable bleachers are controlled according to the individual retractable bleacher system. The controller had to be manufactured separately to order, but the use of a non-standardized controller had the problem of making it difficult to update the product and incurring high costs.

Moreover, in the case of an IoT-based retractable bleacher system controlled in conjunction with a smartphone, an IoT control unit is added in addition to the existing dispenser motor control unit, so not only does the size of the controller become very large, but the IoT control unit and the motor control unit are manufactured by different companies. In some cases, many problems arise in terms of cost, delivery, etc.
