In addition, since the two fixing tables 21 are fixed to the respective rotating belts, when the movable door 20c moves horizontally, the intermediate movable door 20b of the middle portion is also moved together, and the intermediate movable door 20b The speed-adjusting damper 50 fixedly attached thereto is also moved together with the latching jaw 12 so as to be engaged or disengaged, thereby giving the door 30 a buffering function.

Figs. 8A and 9 show a state in which the door 30 is opened, and Fig. 8B shows a state in which the door 30 is being opened and a state in which the door 30 is closed.

 The parallel damper 50 of the present invention is configured such that the operation of one damper 50 is completed and at the same time the operation of one damper 50 is completed, (50) is started.

When the door 30 is completely closed, the engaging portion 52 of the speed adjusting damper 50 fixed to the intermediate door 30b is caught by the engaging jaw 12, and the handle door 30c starts to be opened, When the intermediate door 30b is opened at any point, the spring 55 is stretched to increase the elastic force, so that even if the handle 30C is strongly opened, the spring 55 of the middle door 30b It will be pulled and slowly opened.

 As a result, even if the door is strongly opened, a slow opening effect is generated, so that a buffering function is imparted and the door is stable.

When the handle door 30c and the middle door 30b are continuously opened, the speed adjusting damper 50 (see FIG. 5) fixed to the middle door 30b is detached from the engaging jaw 12, And the spring 55 is maximally extended. The damper 52 is connected to the damper 52 at the same horizontal position as the damper 52, The rod 54 will be in its maximum extended state.

The speed adjusting damper 50 is displaced from the position of the latching jaw 12 and the speed adjusting damper 50 is moved to the position where the door 30 is opened, as shown in the first diagram (c) The spring 55 and the damper rod 54 are kept at the maximum stretched state and fixed to the upper portion of the door 30b and horizontally moved together.

As shown in the second diagram (d) of FIG. 8 (b), when the door is closed again in the open state of (c) and the door is kept closed, the locking part 52 of the speed adjusting damper 50 is locked 12, and the engaging portion 58, which is inserted into the engaging groove 53, is released from the groove 53.

 When the handle door 30c and the intermediate door 30b are closed together at a certain point in the traveling state, the engaging jaw 12 is provided with the engaging touch portion of the speed adjusting damper 50 of the intermediate door 30b, The engaging jaw 12 is completely engaged with the engaging part 52 while the engaging protrusion 57 touches the engaging groove 53. At the same time, the engaging insertion part 58 inserted and received in the engaging groove 53 is withdrawn, As the spring 55 is loosened, the damper rod 54 gradually falls into the cylinder due to the elastic restoring force.

The middle door 30b is closed even if there is no external force due to the spring force of the spring 55. The handle door 30c connected to the intermediate door 30b is naturally forced The effect that the maximum spring 55 is gradually reduced due to the damping action of the damper rod 54 is generated even if there is no force.

As a result, the middle door 30b and the handle door 30c are gradually closed like an automatic door without an external force or a power unit.
