Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1-5 has shown one Embodiment of the folding door of this invention. This folding door is installed at the boundary between the road and the site and is used as a gate in front of the garage.
As shown in FIG. 2, the main folding door has a gate-shaped frame composed of an upper frame 1 and left and right frame frames 10a and 10b standing from the ground G, and a folding door 3 is installed in the frame. As shown in phantom lines in FIG. 2, the folding door 3 is folded along the right hook frame 10a so that the opening between the left and right hook frames 10a, 10b can be opened. A lower frame 11 is embedded in the ground G between the bases of the left and right gutter frames 10a, 10b.

  As shown in FIG. 3, the folding door 3 connects the first to sixth panels 2 a, 2 b, 2 c, 2 d, 2 e, and 2 f through the main joint 12 and the sub-joint 13 from the suspension side. The suspension base end 14 is connected to the end of the suspension base, and the end of the door end 15 is connected to the end of the door end. The door rod 15 is provided with a handle 16 at an intermediate portion in the vertical direction. A traveling tool 17 is provided at the upper ends of the main joint 12, the door rod 15 and the hanging rod 14, and the traveling tool 17 is attached to a main rail 18 provided on the lower surface side of the upper frame 1 as shown in FIG. Guided. A guide pin 19 protrudes downward from the lower ends of the main joint 12, the door rod 15 and the suspension rod 14, and the guide pin 19 engages with the lower frame 11 as shown in FIG. doing. Therefore, the main joint 12, the door rod 15 and the suspension rod 14 move along the upper and lower frames 1 and 11 when the folding door 3 is opened and closed. The sub-joint 13 jumps out to the site side when the folding door 3 is folded.

  As shown in FIGS. 1 and 5, the upper frame 1 is provided with a first subrail 4 along the site side of the main rail 18, and further with a second subrail 20 on the site side thereof. A guide plate 5 is provided so as to project to the site side between the suspension side end portions of the first and second sub-rails 4 and 20 and the eaves frame 10a. As shown in FIG. 4, the guide plate 5 is provided with a first panel guide groove 7 and third and subsequent panel guide grooves 8. Each of the guide grooves 7 and 8 is formed to be gently curved in an S shape so as to move away from the main rail 18 toward the site as it goes toward the suspension base side. In the third and subsequent panel guide grooves 8, the door end side ends are continuous with the first subrail 4.

As shown in FIG. 3 (a) and FIG. 4, brackets 21 are provided projecting to the site side at positions close to the suspension bases of the upper portions of the first panel 2a, the third panel 2c, and the fifth panel 2e. The guide roller 6a, 6b, 6c is provided in the bracket 21. In the state where the folding door 3 is closed (expanded), the guide roller 6a of the first panel 2a is engaged with the door end side end position of the guide groove 7 for the first panel of the guide plate 5, and the third The guide rollers 6 b and 6 c of the fifth panels 2 c and 2 e are engaged with the first sub rail 4 of the upper frame 1.
When the folding door 3 is folded by pushing the handle 16 toward the suspension base side, the guide roller 6a of the first panel 2a moves in the guide groove 7 for the first panel of the guide plate 5 toward the suspension base side. Thus, the first panel 2a and the second panel 2b connected to the first panel 2a support the movement of jumping out to the site side. The guide rollers 6b and 6c of the third panel 2c and the fifth panel 2e sequentially move from the first sub-rail 4 of the upper frame 1 to the third and subsequent panel guide grooves 8 of the guide plate 5, and the third and subsequent panel guides. By moving the inside of the groove 8 to the suspension base side, the third and fifth panels 2c and 2e and the fourth and fifth panels 2d and 2f connected to the third and fifth panels 2c and 2e are supported. Since the guide grooves 7 and 8 are formed in an S-shape, the movements of the panels 2a, 2b, 2c, 2d, 2e, and 2f are slow at the beginning and end of movement, and quickly increase in the middle. Move.

  In the state in which the folding door 3 is completely folded, as shown in FIG. 1, the guide roller 6b of the third panel 2c is located at a position shifted by 30 mm toward the site side with respect to the guide roller 6a of the first panel 2a. The guide roller 6c of the 5 panel 2e is at a position shifted by 15 mm toward the road with respect to the guide roller 6b of the third panel 2c. As described above, when the guide roller 6c of the fifth panel 2e is shifted to the road side with respect to the guide roller 6b of the third panel 2c, the locus 26a of the guide roller 6c of the fifth panel 2e bulges to the site side. Since it becomes smaller and approaches the locus 26b of the guide roller 6b of the third panel 2c, the groove width of the third and subsequent panel guide grooves 8 can be reduced. Further, the third and subsequent panel guide grooves 8 are provided in the first sub-rail as the range from the position where the guide roller 6c of the fifth panel 2e is located to the position where the guide roller 6b of the third panel 2c is located is toward the suspension base side. The inclined portion 9 is gently inclined in a direction away from 4. The inclined portion 9 is formed with a substantially constant groove width that is slightly wider than the diameter of the guide roller 6b.

FIG. 6 shows a state in which the folding door 3 is being folded. As described above, the inclined portion 9 having a substantially constant groove width is provided on the suspension base side of the third and subsequent panel guide grooves 8 as described above. By disposing the guide roller 6c of the fifth panel 2e on the road side with respect to the guide roller 6b of the third panel 2c, the groove width of the third and subsequent panel guide grooves 8 is reduced. Since the movement of each panel when the 6 panels 2c, 2d, 2e, and 2f are folded is accurately regulated and rattling of each panel is suppressed, the panels 2a, 2b, 2c, 2d, 2e, and 2f It can be folded quietly and smoothly with reduced impact noise.
Further, since the guide roller 6b of the third panel 2c is guided by the inclined portion 9 of the third and subsequent panel guide grooves 8, the guide roller is connected to the main joint 12 connecting the second panel 2b and the third panel 2c. Since the force which pushes a door is transmitted via 6b, this main joint 12 moves to the suspension side without stagnation, and the panels (the 1st-4th panels 2a, 2b, 2c, 2d) of the suspension base side Before approaching, the guide roller 6c of the panel closer to the door end (fifth panel 2e) enters the third and subsequent panel guide grooves 8, and the door end panel (fifth panel 2e, sixth panel). Since the panel 2f) is bounced out, a part of the force pushing the door is converted into a bounce force, and the force pushing the door is weakened, so that the momentum when the panels on the suspension side come into contact with each other is also weakened. Can be folded more quietly.
FIG. 7 shows a state in the middle of extending the folding door 3, and by reducing the groove width of the third and subsequent panel guide grooves 8, it is quiet and smooth when extending the folding door 3. FIG.

Further, as shown in FIG. 3A, the folding door is provided with a bracket 22 projecting to the site side at a position near the sub-joint 13 at the upper part of the first panel 2a, the third panel 2c, and the fifth panel 2e. Yes, each bracket 22 is provided with anti-flutter rollers 23a, 23b, 23c. The anti-fluttering rollers 23a, 23b, and 23c are engaged with the second sub rail 20 of the upper frame 1 as shown in FIG. Thereby, when the folding door 3 is extended and closed, the vicinity of the sub-joint 13 that is not engaged with the upper and lower frames 1 and 11 is restricted from flapping in the expected direction due to wind or the like.
As shown in FIGS. 1 and 4, the second subrail 20 is provided with a cutout portion 24 obtained by cutting out the side wall on the site side of the suspension side end portion, and when the folding door 3 is folded, the anti-flutter roller 23 a is provided. , 23b and 23c come out from the excision 24 to the site side. Further, an approach guide 25 is provided at the end of the second sub rail 20 on the suspension base side, and when the folding door 3 is extended from the folded state, the anti-fluttering rollers 23a, 23b, 23c are guided by the entrance guide 25. Thus, the second subrail 20 can be surely entered.

  The present invention is not limited to the embodiments described above. The amount of shift in the expected direction of the guide rollers 6a, 6b, 6c of the first, third, and fifth panels in the folded state can be changed as appropriate. The inclined portion 9 of the guide groove 8 for the third and subsequent panels of the guide plate 5 may be provided so as to connect the guide rollers 6b, 6c shifted in the prospective direction, and the shape thereof is linearly inclined. It may be curved or curved. The number of panels of the folding door 3 is not limited to six and may be eight or more connected. When eight panels are connected, the guide roller of the seventh panel is arranged closer to the rail than the guide roller of the fifth panel in the folded state, and the third and subsequent panel guide grooves are in the folded state. The range from the position where the guide roller of the panel is located to the position where the guide roller of the third panel is located is inclined in a direction away from the rail toward the suspension base side. The installation place and use of the folding door are arbitrary.
