Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide rail for guiding a folding door or the like and a device for closing a groove portion of the guide rail.

[0002]

[Prior art]

 The folding door is composed of a plurality of panels that can be bent, and is suspended by an upper rail to open and close. A slider provided at the lower end is loosely fitted in the groove of the lower rail. Therefore, the slider slides along the groove along with the opening and closing of the folding door and guides the folding door. Therefore, when the folding door is extended and the frontage is closed, the folding door is located above the groove portion of the lower rail, so that the groove portion is in the closed state, but if it is folded and stored. The groove portion is in an open state.

The presence of such an open groove portion on the floor surface not only hinders the opening and closing of the folding door due to the entry of dust or the like, but the groove portion itself obstructs passage. Therefore, when the folding door is folded, it is desirable that the opening groove portion be closed. As a conventional technique, there is known a "gap sealing device for opening frame" according to Japanese Patent Laid-Open No. 3-224986. In this device, the fixed frame (lower rail) part and the blocking movable frame (groove lid) are connected by a tilting arm (link), and the blocking movable frame can be moved up and down by turning the tilting arm. However, in order to use this device, it is necessary to make the depth of the lower rail deep, so it is easy to be constrained in construction, and because the link mechanism is adopted, the structure itself becomes complicated and the stability of the function and Leave a problem for maintenance.

As another conventional example, there is a "folding shutter" according to Japanese Patent Laid-Open No. 4-85476, but the groove closing device of the folding shutter is a guide at a position opposite to the protruding side of the door unit. The lid plate is rotatably fixed to the rail, and a pressing tool having an inclined contact surface is provided at the lower end of the door body on the moving side. Since the above-mentioned pressing tool is provided so as to project from the lower end assembling surface on the moving side (door end), a space (space) for housing the pressing tool is required when completely closing the door body, and the lower end of the vertical frame. When some parts have to be cut out and are composed of multiple units, the moving sides of each door cannot come into contact with each other because of the pressing tool. Further, since the lid plate is rotated by contact between the pressing tool and the lid plate, smooth rotation cannot be performed unless the inclination angle of the pressing tool is long and long, and as a result, the pressing tool is enlarged. is doing.

On the other hand, in the foldable shutter, the lid plate disposed in the opening of the guide rail is rotatably fixed to the guide rail, and the engaging projection of the lid plate is fitted in the engaging groove formed in the rail. And the arm of the cover plate is fitted to the curved surface of the rail. The guide rail and the cover plate are extruded elongate members, and the guide rail is embedded in the floor surface with the cover plate attached. Dust, sand, and the like enter between the engaging protrusions and between the curved surface and the arm, and as a result, the rotating surface is worn or damaged and cannot function as a joint. Of course, no matter how the joint structure is, the smooth rotation (opening / closing) function of the cover plate deteriorates, and the cover plate itself may be deformed or damaged.

[0006]

[Problems to be solved by the present invention]

 As described above, the conventional guide rail and groove closing device have the above problems. The problems to be solved by the present invention are these problems. The opening / closing function of the lid plate (closing body) is stable, the watertightness and airtightness are high when the door is closed, and the closing body is rotated. (EN) Provided is a guide rail and a groove closing device which can easily perform repairs such as replacement of the closing body when the joint portion freely connected and the closing body main body are damaged.

[0007]

[Means for Solving the Problems]

 The guide rail and groove closing device of the present invention has the following features to solve the above problems. First, the guide rail has a split type structure, and has a rail body and a supporting member. A support member is attached to the groove of the rail body so as to have a detachable structure, and the closing body is rotatably attached to the support member via a hinge. Then, the supporting member and the rail main body, or only the supporting member forms a groove portion in which the slider at the lower end of the door is guided, and the groove portion is closed when the closing body falls down.

On the other hand, although the rotation control body is attached to the lower end of the door end frame of the door, the rotation control body is arranged at the lower end of the door end frame and has a guide surface having a rake angle. , The tip of it is of a size that does not protrude from the summing surface of the door frame. Then, the closing body comes into contact with the rotation control body and rotates to open the groove. However, a rod-shaped rotation assisting tool projects from the end of the closing body, and the rotation assisting tool rotates. Rotate the closing body by hitting the guide surface of the motion control body. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
