Description

Slide Door {Sliding Door System}

The present invention relates to a slide door opening and closing device for a top vehicle, and in detail, it improves maintaining the inherent bearing capacity of the door panel even if the center sliding rail is deleted, and at the same time, the appearance is beautiful and the door is more stable by deleting the center sliding rail. It relates to a slide door configured to be opened and closed flexibly.

In general, looking at the typical structure of the opening and closing device for opening and closing the slide door for a small top car, such as a courier vehicle or an ambulance illustrated in FIG. 1, the upper and lower sliding rails 51 and 61 of a container body pressed and formed into an upper opening using an iron plate. The sliding door panel 20, which is also formed by pressing steel plate and has rollers 53 and 63 on one side thereof, is installed, and the sliding door panel 20 has an opening / closing shaft member installed on both sides of the front of the door. 131 is configured to be rotatably connected with the upper and lower swing plates (50, 60).

In general, the slide door opening and closing device for a top vehicle having such a structure has a sliding rail 51 having a top open shape, and thus the guide roller 51 having a small diameter that the sliding door panel 20 has is always left from the sliding rail 51. In addition, the sliding rail 51 and the sliding door panel 20 pressed by the steel plate is weak in strength, so it may be easily deformed even by a weak impact or force from the outside. Because of the loss of the door panel 20 causes frequent safety accidents.

In addition, the upper open sliding rail 51 is easily infiltrated with moisture or various foreign matters due to the snow rain, which hinders the sliding operation of the door with the deformation due to the impact from the outside can not expect a flexible sliding operation.
