Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a hanging guide for a folding door that movably hangs the upper ends of both ends of a folding door composed of two doors that are foldably connected by a hinge. It relates to the device.

(Prior Art and Problems Thereof) This type of hanging guide device for a folding door includes a pair of roller units attached to the upper ends of both ends of the folding door, and a guide for movably hanging the folding door via both roller units. Each roller unit consists of rails, and each roller unit has a pair of left and right horizontal shaft rollers pivotally supported by a bearing member rotatable around a vertical support shaft protruding from the door body, and in order to regulate the orientation of the horizontal shaft rollers. Requires vertical axis roller.

However, since both ends of the folding door are suspended by the horizontal axis roller, the horizontal axis roller needs to be arranged as close as possible to both ends of the folding door, and thus the vertical axis roller is located inside the horizontal axis roller. Will be placed in. As a result, when the folding door is folded to bring both roller units closer to each other, the vertical axis rollers of each roller unit come closer to each other. It will limit the folding angle of the door. In other words, the conventional folding guide for a folding door of this type cannot sufficiently reduce the folding angle of the folding door.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
It consists of a pair of roller units and a guide rail that movably hangs both ends of the folding door through both roller units, and each roller unit has a bearing member rotatable around a vertical support shaft protruding from the door body. Together with
Horizontal shaft rollers are respectively supported on both the left and right sides of the bearing member, and when the bearing members of both roller units are brought close to each other, projecting portions are projected from the bearing member, and at the same time, Vertical shaft rollers are respectively supported on the lower side and the upper side of the upper side protruding portion, and the guide rail includes a pair of left and right horizontal shaft rollers for supporting the pair of left and right horizontal axis rollers of each roller unit. A supporting rail portion, a through slit portion that guides the lower vertical shaft roller at an intermediate lower side of both supporting rail portions, and a groove shape that guides the upper vertical shaft roller at an intermediate upper side of both supporting rail portions. A hanging guide device for a folding door, which is provided with a rail portion, is proposed.

(Operation of the device) The pair of left and right horizontal shaft rollers of each roller unit rolls and rolls on the supporting rail portion of the guide rail as the folding door moves. That is, the direction of the bearing member that axially supports the horizontal shaft roller is that the vertical shaft roller that is axially supported by the protrusion is fitted into the through slit portion or groove rail portion of the guide rail. , The length of the guide rail is restricted. Therefore, the horizontal shaft roller can smoothly rotate and roll.

When the folding doors are folded and the two roller units are brought close to each other, the vertical axis rollers of both roller units and the protrusions that support the rollers do not abut each other but overlap vertically without overlapping, so at least one roller Both roller units can be brought sufficiently close to each other to the same state as when the vertical axis roller is not pivotally supported on the unit (hence no protrusion). That is, the folding angle of the folding door can be made very small.
