Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a folding door device composed of a plurality of units in which a lower rail has a split type closing body. Here, the above-mentioned unit refers to a folding door that moves independently along the rail and is folded.

[0002]

[Prior art]

 When the folding door is folded, the lower rail that guides the lower end of the folding door has an opening in its groove that allows dust on the floor to enter and interfere with the opening and closing of the folding door. However, the presence of open ditch on the floor hinders traffic. It is desirable to cover the groove of the lower rail so that dust will not enter when the folding door is folded and it will not obstruct passage.

By the way, as a related art related to this, there is known a "gap sealing device for an opening frame" according to Japanese Patent Laid-Open No. 3-224986. In this device, the fixed frame (lower rail) part and the closing movable frame (groove cover) are connected by a tilting arm (link), and the blocking movable frame can be moved up and down by turning the tilting arm. In order to use this device, the depth of the lower rail must be 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.

Therefore, in order to solve these conventional problems, the applicant has filed an application for “a groove closing device for the lower rail” on June 22, 1992 (Japanese Patent Application No. 4-49819). This lower rail groove closing device has a closing body that covers the groove and is pivotally attached so that it can be opened and closed.A turning assist tool is projected from the end of the closing body, while the lower end of the door tip frame is attached to the lower end of the door. A rotation control body is provided, and the rotation control body has a guide surface that is inclined at a rake angle, and the tip of the guide surface is formed at a position that does not protrude from the summing surface of the door frame. By providing the rotation assist tool in this way, the rotation control body can be made compact, and even if the closure body has a split type structure, opening and closing of each closure body and opening and closing of the door body can be performed without any trouble. Can be done. However, when the folding door is composed of multiple units, the conventional idea is that when the independent folding door is opened, not only does the lid stand upright, which obstructs passage, but it may damage the closing body. If there is, or if you slide another folding door, the closed body will obstruct the sliding.

[0006]

[Problems to be solved by the present invention]

 In this way, when installing a folding door composed of multiple units in the frontage, there are the above problems. The problems to be solved by the present invention are these problems, and to provide a folding door device in which a split type closing body and each folding door can be smoothly opened and closed.

[0007]

[Means for Solving the Problems]

 The folding door device according to the present invention has a plurality of folding doors (a plurality of units) mounted in the frontage, and a split type closing body is provided in the groove portion of the lower rail. Then, a rotation control body that does not protrude from the tip of the frame is provided at the lower ends of both ends of the folding door. However, the first unit on the suspension side is provided with a rotation control body only at the front end door frame. Here, the rotation control body has a guide surface that is inclined at a rake angle, and the rotation control body abuts against a rotation assisting tool that is provided at the end of the closure body so that the closure body is erected.

As described above, the closing body has the split type structure, and the rotation assisting tool is provided on the closing body so as to project from the end portion. ing. However, in the vicinity of the joint of each unit when the folding door is extended, the closing body located on the hanging side is provided with rotation assisting tools at both ends thereof, and the closing body located on the door end side is equipped with it. No turning aids are provided. Further, it is desirable that the length of the split-type closing body is as large as two panels of the folding door.

[0009]

[Action]

 By the way, in the folding door folded on the suspension base side, if the door end frame is pulled when the front door is extended when closing the frontage, the rotation assisting device is attached to the rotation control body provided on the door end frame. Therefore, the closed body is raised. Here, the closing body, which is arranged near the joint portion of the folding door and has the rotation assisting tool at both ends, simultaneously raises the closing body without the rotation assisting tool on the door end side. On the contrary, when the folding door in the extended state is folded to the hanging side, the first unit on the hanging side is folded and retracts. Close the groove. Also, when moving the second unit to the suspension side, if the closing bodies at the joints with the rotation assisting tools protruding at both ends are erected, each closing of the portion where the first unit is arranged is closed. All the body gets up. The same works for the third and fourth units. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 shows a folding door device composed of two units, where a is a front view and b is a plan view of a closing body attached to a groove portion of a lower rail. The folding door is well-known, and is composed of a plurality of panels 1, 1, ... Which are flexibly connected through joints 2, 2, ..., and suspended on an upper rail 3 through a traveling tool (not shown). The lower end is guided by the lower rail 4. A door end frame 5 is provided at the tip of the folding door of each unit, and a hanging frame 6 is provided at the hanging base side. Further, the closing bodies 7, 7 ... Closing the groove portion of the lower rail 4 have a split type structure and are rotatably attached to the shaft.

FIG. 2 shows a groove closing device of the lower rail in a state where the folding door is folded. In the figure, 7 is a closing body, 8 is a rotation assisting tool, and 9 is a rotation control body. The closing body 7 is attached to the lower rail 4, the groove portion 10 of the lower rail 4 is closed, and the folding door. When is extended, the closing body 7 stands up and opens the groove 10. The closing body 7 is a plate-shaped body having a predetermined width, and can be opened and closed by being attached to the receiver 11 via the hinge 12. Moreover, the receiver 11 can be attached to and removed from the lower rail 4 with screws.

The lower rail 4 is composed of an outer member 13 and an inner member 14. The inner member 14 is put in the outer member 13 having a substantially U-shaped cross section, and both edges 15a and 15b forming an inverted U-shaped cross section are the outer member. The side piece 13 is covered, and the edge 15 and the side piece of the outer member 13 are welded. Further, the above-mentioned receiver 11 is provided with a support 16 having a cushion material adhered on the side of the edge 15b, and is installed in the inner member 14 and screwed. FIG. 2 shows a case where the closing body 7 is collapsed to close the groove portion 10, and the closing body 7 is supported by a support 16 and the tip end of the rotation assisting tool 8 protruding from the end portion is located at the lower end of the door end frame 5. It is in a state of being close to the attached rotation control body 9.

FIG. 3 shows details of the rotation control body 9. Although the rotation control body 9 is not necessarily limited to the shape shown in the figure, it has a guide surface 17 inclined at a rake angle, and the tip of the guide surface 17 has a size that does not protrude from the door end frame 5. . Here, although the guide surface 17 is formed as a flat surface, it may be formed as a curved surface. Further, the rotation control body 9 is attached to the lower end of the door frame 5 by forming a shield plate 19 on the side opposite to the side surface 18, but the shield plate 19 is extended to the lower end of the rotation control body 9. Thus, the guide surface 17 cannot be seen from the shield plate 19 side.

FIG. 4 a is a perspective view showing the groove closing device, but the closing body 7 is closed and the rotation assisting tool 8 is close to the guide surface 17 of the rotation control body 9. Therefore, when the folding door is extended to close the frontage, and the door frame 5 is moved, the tip of the rotation assisting tool 8 comes into contact with the guide surface 17 of the rotation control body 9 and the rotation assisting tool 8 is moved. Is scooped up along the guide surface 17. Therefore, the closing body 7 rotates about the hinge 12, opens the groove portion 10 of the lower rail 4 as shown in FIG. 4b, and the closing body 7 stands up. The rotation control body 9 slides in the groove 10 as a slider to extend the folding door along the rail. The closing bodies 7, 7 ... Having a split structure sequentially open the respective closing bodies 7, 7 ... As the rotation control body 9 moves.

FIG. 5 shows a state in which the closing body 7 stands up and opens the groove portion 10. In this case, the closing body 7 does not stand upright and is leaning against the rotation control body 9, If the rotation control body 9 retracts, it can fall down by its own weight. Also in this, the rotation assisting tool 8 at the end of each closing body 7 is gradually separated from the rotation control body 9 to close the groove 10. The closing body 7, the rotation assisting tool 8, and the rotation control body 9 shown in FIGS. 2 to 5 are merely specific examples, and the present invention is not limited to these embodiments.

By the way, the folding door device of the present invention comprises a plurality of units, and the folding door of each unit can be independently opened and closed, or can be slid while extended. As shown in the schematic view of the two-unit folding door device in FIG. 1, the first unit A is located on the hanging side, the second unit B is located on the door end side, and the door end of the second unit B is located. The lower ends of the frame 5b and the hanging frame 6b, that is, the lower ends of the frames on both sides, are attached with the rotation control bodies 9b and 9b, and the first unit A on one side has the rotation control body 9a only at the lower end of the door frame 5a. Have .. attached to the lower rail 4 project toward the suspension bases as shown in FIG. However, in the vicinity of the joint between the first unit A and the second unit B, the closing body 7a on the first unit side projects the rotation assisting tools 8a and 8b from both sides thereof, and the one of the second unit The rotation assisting tool 8 is not provided on the closing body 7b on the unit side.

Therefore, when both units A and B are pulled toward the hanging side and folded and the door frame 5 is pulled to extend the folding door, the door frame 5b of the second unit B is In response to the movement, each of the closing bodies 7, 7 ... Abuts on the rotation assisting tool 8, 8 ..., and the closing bodies 7, 7 ,. Similarly, when the first unit A is extended, the closing bodies 7, 7 ... Stand up in sequence. However, when the door frame 5b approaches the closing body 7a, if the rotation control body 9 comes into contact with the rotation assisting tool 8a, the closing body 7a stands up and the adjacent closing body 7b also stands up at the same time. Become.

Here, in a state where the door end frame 5b of the second unit B is in contact with the vertical rail of the frame and arranged at a predetermined position, the suspension base frame 6b is disengaged from the rotation assisting tool 8b of the closing body 7a. The closing body 7a falls down. In the state of FIG. 1a in which the first unit A and the second unit B are extended, all the closing bodies 7, 7 ... Stand upright. When the first unit A is folded from this state, the doorframe 5a of the first unit A moves backward to the hanging side, but with the backward movement, the closing body 7a and the other closing bodies 7, 7 ... Fall down.

On the other hand, when the second unit in the extended state is folded, the second unit B is slid to the suspension base side and folded at the suspension base side as it is. Since 6b is also provided with the rotation control body 9b, if it is slightly moved, it contacts the rotation assisting tool 8b to raise the closing body 7a. When the closing body 7a stands up, all the other closing bodies 7, 7 on the suspension base side also stand up, so that the closing body 7a can move along the open groove portion 10 of the lower rail 4 and move. As a result, the closing bodies 7, 7 ... Removed from the door end frame 5b are sequentially collapsed to close the groove portion 10.

The closing body 7 is thus configured as a split type, and the closing bodies 7, 7 ... Open and close the groove portion 10 of the lower rail 4 as the folding door moves. Therefore, it is desirable that the length is twice the width of the panel so that one closing body 7 is collapsed every time two panels of the folding door are folded. Of course, the length may be smaller or larger than this length. Therefore, when only a part of the door end side is opened, one closing body 7 is made to fall by folding the two panels on the suspension side, and if four panels are folded, it will be 2 The closures 7, 7 are designed so that they do not fall over and hinder access. Of course, the part of the opening is not limited to the door frame side, and the same is true at the center. As described above, the folding door device according to the present invention comprises a plurality of units, and the lower rail is provided with the split type closing body, and the following effects can be obtained.
