Description

  The present invention is applied to a free-type suspension door. In a state where the connecting shaft of the runner is supported, the suspension door can be opened and closed while the suspension door is temporarily held at a fixed position, and the suspension door is fully closed. The present invention relates to a bearing stopper with a gap closing mechanism for a sliding door runner that eliminates a gap between the hanging doors by applying an urging force to the central side of the hanging door.

  The conventional folding door is provided with an upper runner that can run along the upper rail at the upper end of the door and the upper end of the door, respectively, and the lower rail at the lower end of the door and the lower end of the door. A lower runner that can run along the rail is provided, and a free type that can be run along the running rail in a state where the entire folding door is bent in a V shape, and the door side of the folding door is moved up and down by a fixed bearing device. There is a fixed type that is fixed and held at the end position of the rail, and only the door end side is movable along the upper and lower rails. In recent years, these intermediate types are shown in Patent Documents 1 and 2 below. In addition, a free type has been proposed that can be changed to a fixed type by a bearing stopper.

  In the case of the free type folding door, the width of the left and right of the opening is set to be slightly larger than the total width when all the hanging door panels are fully closed due to the pivotal movement of the individual folding door panels around the runner axis. Therefore, there is a problem that a gap is generated between adjacent panels at the center of the folding door.

  Therefore, in Patent Document 3 below, a runner catcher for a free folding door is proposed in which the runner is held so that the free type folding door can be changed to a fixed type folding door, and the gap formed between the central folding doors can be removed.

As shown in FIG. 11, this free folding door runner catcher is a free folding door runner catcher that is attached to the side end of the guide rail 60 and engages and captures the runner 52 provided on the upper surface side end of the panel body. The guide frame 50 fixed to the guide rail 60, the pressing block 53 supported by the guide frame 50 so as to be reciprocable along the running direction of the runner 52, and the pressing block 53 is pushed and urged from the guide frame 50. And a catching tool 55 that engages and captures the connecting body 56 provided on the runner 52 is provided at the outer end of the pressing block 53, and the connecting body 56 of the runner 52 is captured by the catching tool 55. In this state, the panel pair receives the spring force of the springs 54 and 54 and is urged to move toward the center of the opening.

  However, in the case of the runner catcher, it comprises a guide frame 50, a pressing block 53 accommodated therein so as to be able to reciprocate, and springs 54, 54 for urging the pressing block 53. There is a problem that the number of parts is large, such as requiring a female screw body and screws for fixing the guide frame 50 to the rail, and the cost cannot be reduced. The pressing block 53 can be reciprocated along the guide frame 50 within a predetermined range. However, when the folding door is opened and closed, the pressing block 53 can freely reciprocate. There were problems such as rattling and unstable opening and closing due to movement. Furthermore, since the engagement force of the catch portion of the runner 52 cannot be adjusted, it is necessary to respond to the needs of the resident, for example, since it is mainly used in a fixed type, so that it should be firmly held so that it cannot be easily pulled out. Or because it is mainly used as a free type, problems such as being unable to respond to requests such as making it possible to easily disengage, or because the engagement and disengagement force is too strong, only women and children can switch easily. There was a problem that there were things that could not be done.

  Therefore, the main problem of the present invention is that it is possible to change a free type folding door to a fixed type folding door, and in the bearing stopper with a gap closing mechanism that can remove the gap of the folding door formed in the center, the structure is simplified, the number of parts The purpose of this is to reduce the cost significantly and to enable stable opening / closing operation without rattling or movement when the panel is opened / closed when the fixed type is used.
