Hereinafter, a method of operating a door car will be described in more detail with reference to FIGS. 4 to 8.

First, by rotating the height adjustment bolt 30 so that the wheel is seated in a position suitable for the height of the guide rail to move the adjustment nut 60 connected to the height adjustment bolt 30 in the left and right directions. In other words, in order to adjust the position of the wheel cover 40 in which the wheel 50 is installed, a process of moving the control nut 60 seated on the upper portion of the wheel cover 40 in the left and right directions is performed.

More specifically, when the height of the guide rail is high, the wheel should be lowered so that the door-to-door can be stably driven along the guide rail. To this end, the height adjustment bolt 30 is fixed to one side by the adjustment bolt clip 70 in a counterclockwise direction. That is, when the height adjustment bolt 30 is rotated in the counterclockwise direction, the adjustment nut 60 is moved to the left side by the thread formed in the height adjustment bolt 30 as shown in FIGS. 4 and 7. In addition, one end of the wheel cover 40 which is in contact with the lower portion of the adjusting nut 60 is lowered by the adjusting nut 60, and eventually the wheel 50 installed on the wheel cover 40 is lowered. It rests on the rails.

On the contrary, when the height of the guide rail is low, the wheel must be raised so that the door-to-door vehicle can stably run along the guide rail. To this end, the height adjustment bolt 30 is rotated in a clockwise direction. That is, when the height adjustment bolt 30 is rotated in the clockwise direction, the adjustment nut 60 is moved to the right by the thread formed in the height adjustment bolt 30 as shown in FIG. 5. In addition, one end of the wheel cover 40 in contact with the lower portion of the adjustment nut 60 is raised by the adjustment nut 60, and eventually the wheel installed in the wheel cover 40 is also raised. At this time, the rotation direction of the height adjustment bolt 30 may be changed according to the structure of the screw thread formed in the height adjustment bolt (30).

As such, according to the present invention, the wheel cover 40 is formed in a structure in which the wheel nut 40 is separated from the adjustment nut 60, and the wheel cover 40 is not fixed to other components except the fastening pin. Compared with a conventional door car having a structure connected to an adjusting nut, the falling distance of the wheel cover 40 is long. Accordingly, when the wheel 50 is spaced relatively far from the guide rail by a bouncing phenomenon, unlike the conventional doorway in which the wheel is separated from the guide rail, the doorway according to the present invention has a wheel 50 inserted into the guide rail. It has the advantage that it does not deviate from the guide rail by maintaining the state.

However, the door according to the present invention has a long descending distance of the wheel cover 40, the wheel is installed, so even if the user lifts the sliding window according to the user's choice, the wheel cover 40 is maintained in the state inserted into the guide rail to open the sliding window Problems can arise that are difficult to separate from the guide rail.

In order to solve this problem, the present invention includes a catching ring 48 and a catching means 62. Specifically, as shown in FIGS. 6 and 8, the height adjustment bolt 30 is rotated so that the adjustment nut 60 contacts the support 20 or the clip 70 for the adjustment bolt 60. Move). As such, when the adjusting nut 60 is in contact with the support 20 or the clip 70 for the adjusting bolt, the force for pressing the wheel cover 40 downward is released, and the wheel cover 40 is raised. When the wheel cover 40 is raised, the locking ring 48 formed on the wheel cover 40 is seated on the locking means 62 of the adjustment nut 60. Accordingly, the wheel cover 40 is limited by movement of the adjustment nut 60 so that the wheel cover 40 does not lower even if the sliding window is dropped from the guide rail.

In other words, in the door car according to the present invention, even when the door is opened and closed by sliding foreign matter such as stones and dust, the wheel cover 40 and the pressure providing means 80 installed therein automatically adjust the height of the wheel. To prevent it from deviating from the guide rail.

The door to door car that operates so as not to be detached from the sliding window by adjusting the height of the wheel even when the phenomenon of the door is bounced when the door is opened and closed simply corresponds to a known technology, the door car formed by the known technology Since the moving distance of the wheel cover 40 that adjusts the height of the wheel is limited, when a bounce phenomenon that occurs outside the maximum moving distance of the wheel cover 40 occurs, a problem may arise from the guide rail.

However, since the car door according to the present invention does not have a component that restricts the movement of the wheel cover 40 in addition to the fastening pin, the falling distance is improved compared to the conventional car door. Therefore, when using the door-to-door car according to the present invention, since sliding windows are not separated from the guide rail due to the bouncing phenomenon, breakage of the sliding windows due to the separation does not occur and thus the stable use of the sliding windows is possible.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It can be understood that it is possible.
