Further, the folding door device 1 includes a suspension member 22 at the end of the door 10 disposed on the left side of FIG. The suspension member 22 is engaged with the vertical frame 6.

  FIG. 2 is a horizontal sectional view of the folding door device 1 when the door bodies 10, 10,... Are folded. In FIG. 2, the upper side of the paper is the indoor side, and the lower side of the paper is the outdoor side. In FIG. 2, some symbols are omitted for easy viewing. As described above, the folding door device 1 is arranged such that the doors 10, 10,... Are folded to the vertical frame 6 side when the folding door device 1 is opened. At this time, the doors 10, 10,... As a result, the opening is large when opened, and the opening can be used effectively. As can be seen from FIG. 2, the adjacent doors 10 and 10 are connected to each other by hinges 20 at their ends. The hinge 20 and the end portion of the door body 10 are rotatably connected to each other by connecting portions 16, 16, 16,... Around the end portion. Then, one end moves along the upper horizontal frame 3 and the lower horizontal frame 4 (see FIG. 1), and the other end moves so as to protrude indoors. The hinges 20, 20,... That move along the upper horizontal frame 3 and the lower horizontal frame 4 are provided with an upper shaft 30, wheels 32, 32, and the like as moving means, as will be described later (see FIG. 3). By such an operation, the doors 10, 10,... Are folded.

  FIG. 3 is a longitudinal sectional view of the folding door device 1 in a posture in which the door bodies 10, 10,. In FIG. 3, the right side of the drawing is the indoor side, and the left side of the drawing is the outdoor side. The folding door device 1 includes an upper shaft 30, a wheel shaft 31, and wheels 32 and 32 as moving means at the upper end of the hinge 20 that moves along the upper horizontal frame 3 and the lower horizontal frame 4. Specifically, the upper shaft 30 extends vertically from the upper end portion of the hinge 20 toward the inside of the upper horizontal frame 3. The wheel shaft 31 is provided at the upper end of the upper shaft 30 in parallel to the indoor / outdoor direction, and the wheels 32 and 32 are rotatably provided at both ends of the wheel shaft 31 with the wheel shaft 31 as an axis. Further, the lower end portion of the hinge 20 has a lower shaft 35 extending vertically toward the inside of the lower horizontal frame 4 and a wheel 36 having the lower shaft 35 as a rotation axis. The upper shaft 30, the wheel shaft 31, the wheels 32 and 32, the lower shaft 35, and the wheel 36 are the upper horizontal frame 3 and the lower horizontal among the hinges 20, 20,... Provided in the folding door device 1 as described above. Each of the hinges 20, 20,... Moving along the frame 4 is provided.

  The upper horizontal frame 3 includes a rail member 25 that is hollow and has a lower side opened in a cross section, and door guides 26 and 27 that are attached to the lower end of the rail member 25 along the longitudinal direction of the rail member 25. Have. The rail member 25 has rails 25a and 25a, which are pieces extending from the side walls inside and outside the room toward the inside of the rail member 25 in the cross section. The rails 25a and 25a can be moved by rolling the wheels 32 and 32 on the upper surfaces of the rails 25a and 25a. The door guides 26 and 27 extend downward from the lower end of the rail member 25 to a height position slightly below the upper end of the door 10 in the cross section. Furthermore, the door guides 26 and 27 have pieces 26a and 27a extending from the lower ends of the door guides 26 and 27 toward the door 10 side. The pieces 26a and 27a are formed so that the distance between the opposing ends is slightly larger than the thickness of the door body 10, thereby preventing the door body 10 from moving greatly in the indoor and outdoor directions, so-called door body. Ten “flapping” can be suppressed.

  The lower horizontal frame 4 is a member that is hollow and has an open upper side in the cross section. The lower horizontal frame 4 has side walls 4a and 4a standing in parallel and having a predetermined interval on the inner side in the cross section. The wheel 36 can roll between the side walls 4a, 4a.

  Furthermore, the member with which the folding door apparatus 1 is provided is demonstrated. 4 shows the folding door device 1 including the door body guides 26 and 27, the resistance members 40 and 40 attached to the door body guide 27, and the frame side member 61 of the door body steady rest 60 (see FIG. 13) from above. FIG. The upper side of the paper is the indoor side and the lower side of the paper is the outdoor side. Thus, the door guide 27 on the outdoor side of the door guides 26 and 27 is arranged so as to be passed between the vertical frames 5 and 6. On the other hand, the indoor door guide 26 extends substantially parallel to the door guide 27 from the vertical frame 5, but is provided so as not to reach the vertical frame 6. This is because the doors 10, 10,... Are protruded and folded indoors at the portion where the door guide 26 is not disposed, so that it is not appropriate to restrain the doors 10, 10,. .

  Further, two resistance members 40, 40 are attached to the side end portion of the door guide 27 close to the vertical frame 6 so as to be aligned in the longitudinal direction of the door guide 27 and directed toward the indoor side. The resistance member 40 will be described in detail later. The door steady rest 60 will also be described in detail later.

  FIG. 5 is a longitudinal sectional view of the folding door device 1 at a portion where the resistance member 40 is provided, and is a view showing an upper end portion thereof. In FIG. 5, the right side of the drawing is the indoor side, and the left side of the drawing is the outdoor side. Since the resistance member 40 is provided, the indoor door guide 26 is not arranged. As can be seen from FIG. 5, the resistance member 40 extends from the door guide 27 toward the indoor side, and is disposed so that the end on the indoor side is on the movement path of the upper shaft 30. The relationship between the upper shaft 30 and the resistance member 40 will be described in detail later.

  Next, the resistance member 40 will be described. 6A and 6B are perspective views of the resistance member 40, in which FIG. 6A is viewed from the diagonally lower side on the indoor side and FIG. 6B is viewed from the diagonally upper side on the indoor side. The resistance member 40 includes a base 41 that is a flat plate arranged vertically, a support piece 42 that is a flat plate extending from the upper end surface of the base 41 in a direction perpendicular to the base 41, and a lower side of the support piece 42. Arm 44. The base 41 is provided with holes 41a and 41b penetrating in the thickness direction, and is attached to the upper horizontal frame 3 by a fixing member through the holes 41a and 41b. The support piece 42 has a cutout portion 42 a that is partially cut out at the base 41 side end of the support piece 42. The arm 44 is a member having a shape that becomes narrower as the distance from the base 41 increases in the horizontal cross section. A thick portion of the arm 44 is disposed immediately below the support piece 42 and is attached to the support piece 42 by a rotation shaft 43 whose axial direction is the vertical direction. On the other hand, the tip on the narrow side of the arm 44 is disposed so as to protrude from the support piece 42. Therefore, the arm 44 can be rotated about the rotation shaft 43.

  Further, the resistance member 40 will be described. FIG. 7A is a plan view and FIG. 7B is a side view of the resistance member 40. 7 (a) and 7 (b), the members are shown through appropriately. The resistance member 40 has a winding spring 45. The winding spring 45 is indicated by hatching. A portion around which the winding spring 45 is wound is wound around the rotation shaft 43. One of the two ends of the winding spring 45 extends toward the base 41, and its tip is bent upward. The bent end portion is disposed in contact with the side wall of the cutout portion 42 a of the support piece 42. The other end of the winding spring 45 is disposed inside a groove 44 a provided in the thickness direction of the arm 44. Here, since the notch 42a has a predetermined width (vertical direction in FIG. 7A), the end of the winding spring 45 on the base 41 side has the width of the notch 42a. Can move in a range of directions. On the other hand, the end portion on the arm 44 side of the winding spring 45 is formed so that the width of the groove 44a is substantially the same as the wire diameter of the winding spring 45, so that the end portion cannot move only by the end portion.

  As shown in FIG. 7A, the arm 44 has one side (surface) 44b parallel to the direction perpendicular to the base 41 (parallel to the left-right direction on the paper surface) and the other side ( The surface) 44c is attached so as to have a predetermined angle (“A” in FIG. 7A) with respect to the perpendicular direction.

  Next, the operation of the resistance member 40 and the characteristics at that time will be described. FIG. 8A shows a scene in which a force for pushing the surface 44b of the arm 44 (force in the direction of a straight arrow in FIG. 8A) is applied to the arm 44 of the resistance member 40. FIG. FIG. 8B shows a scene where a force pressing the surface 44c of the arm 44 (force in the direction of the straight arrow in FIG. 8B) is applied to the arm 44 of the resistance member 40.

  When a force is applied as shown in FIG. 8A, the end of the winding spring 45 on the base 41 side is brought into contact with one side surface of the notch 42a, and the winding spring 45 is urged, so that the arm 44 Produces a force in the opposite direction to the force applied to the arm 44. Therefore, in such a case, a large force resisting the applied force is generated. On the other hand, when a force is applied as shown in FIG. 8B, the end of the winding spring 45 on the base 41 side follows the rotation of the arm 44 so that the inside of the notch 42a is within the notch 42a. Move until it contacts the other side. At this time, since the winding spring 45 is not biased, the arm 44 does not generate a resistance force that repels the applied force.

  The folding door device 1 includes the resistance member 40 having such a configuration and operation characteristics. Next, arrangement | positioning to the folding door apparatus 1 of this resistance member 40 is demonstrated. FIG. 9 is an enlarged view schematically showing the positional relationship between the resistance members 40, 40 and the doors 10, 10,... In a posture in which the doors 10, 10,. It is the figure which looked at the folding door apparatus 1 from the top. Therefore, in FIG. 9, the upper side of the paper is the indoor side and the lower side of the paper is the outdoor side. Two resistance members 40, 40 in the present embodiment are provided, and are arranged side by side on the door guide 27 with a predetermined interval toward the indoor side. More specifically, one resistance member 40 is disposed on the door tip side of the upper shaft 30 provided in the hinge 20 closest to the door tip member 21 in a folded posture of the door bodies 10, 10. The other resistance member 40 is provided on the door end side of the upper shaft 30 provided on the most vertical frame 6 side. And the indoor side front-end | tip of the arms 44 and 44 of the resistance members 40 and 40 is arrange | positioned on the track | orbit of a movement of the upper shaft 30, 30, ....

  Further, as can be seen from FIGS. 9 and 5, the resistance members 40, 40 are arranged so as not to protrude on the inside and outside of the upper horizontal frame 3, and are housed inside the upper horizontal frame 3. Thereby, there is no member which protrudes from the upper horizontal frame 3, and the folding door apparatus 1 which has the outstanding design property can be provided.

  In the present embodiment, two resistance members are provided, but it is not always necessary that there are two resistance members. Three or more doors may be provided depending on the number of doors used.

  Next, the relationship between the doors 10, 10,... And the resistance members 40, 40 when the doors 10, 10,. FIG. 10 is a diagram illustrating, in order, the process of developing the doors 10, 10,... FIG. 11 is a diagram illustrating the operation of the resistance member 40 disposed on the door-end side in order. (A) to (d) in FIG. 11 correspond to (a) to (d) in FIG. 10 and 11, the upper side of the paper is the indoor side, and the lower side of the paper is the outdoor side.

  In the postures shown in FIGS. 10A and 11A, the doors 10, 10,... Are folded. At this time, the upper shaft 30 is disposed in contact with the surface 44 b of the arm 44 of the resistance member 40 on the vertical frame 6 side of the resistance member 40. From this posture, the door tip member 21 is moved along the door guide 27 in the direction in which the doors 10, 10,... Are deployed as shown in FIG. In this case, the upper shaft 30 in contact with the resistance member 40 also tries to move in the direction of deployment following the movement. However, as shown in FIG. 11 (b), the resistance member 40 is in the state shown in FIG. 8 (a), so that the upper shaft 30 is latched by receiving resistance and its movement is restricted. Thereby, only the two door bodies 10 and 10 which exist in the door tip side rather than this hooked upper axis | shaft 30 expand | deploy appropriately. If the door end member 21 is further moved in the direction of deployment from this state, the deployment force then becomes a force for moving the upper shaft 30 that is hung by the resistance member 40 and restricted in movement. And this force becomes larger than the resistance force by the urging | biasing of the arm 44, and the upper axis | shaft 30 moves to the direction of expansion | deployment like FIG.11 (c). When the closing of the folding door device 1 is further continued, the upper shaft 30 is detached from the resistance member 40 and returns to the posture shown in FIG. And the operation | movement of Fig.11 (a)-FIG.11 (d) is repeated about the upper axis | shaft 30 which moved next. Thereby, it expand | deploys in order from the door-end side and can close the folding door apparatus 1 appropriately.

  On the other hand, folding of the doors 10, 10,... Is performed in the following order. 12 corresponds to FIG. 11 when the doors 10, 10,... Are folded, and the order in which the doors 10, 10,... Are folded is shown in FIGS. It is. When the doors 10, 10,... Are folded, the upper shaft 30 is first brought into contact with the surface 44c of the arm 44 as shown in FIG. Even if the folding is continued, the arm 44 rotates as shown in FIG. 12B, so that the state described with reference to FIG. 8B is obtained, and almost no resistance is generated when the upper shaft 30 moves. When the opening is further continued from the state of FIG. 12B, the winding spring 45 is slightly biased and resistance is generated when the arm 44 is rotated, but the surface 44c has a predetermined inclination as described above. Therefore, the resistance can be kept small. When the upper shaft 30 is detached from the arm 44, the posture shown in FIG. Further, even if it does not return completely, at least the posture shown in FIG. 12B is maintained. Therefore, the next upper shaft 30 associated with the folding of the doors 10, 10,... Is brought into contact with the surface 44c, and the above operation is repeated with respect to the next upper shaft 30.

  By the relationship between the resistance member 40 and the upper shaft 30 as described above, it is possible to provide the folding door device 1 capable of folding and unfolding the appropriate door bodies 10, 10,. Regardless of how many resistance members are provided, each of the resistance members causes the doors 10, 10,.

  Next, the door steady rest 60 will be described. FIG. 13A is a longitudinal section of the folding door device 1 at a portion where the door body steady rest 60 is installed. FIG. 13B is a plan view of a portion where the door steady rest 60 is disposed in a posture in which the doors 10, 10,. The door body steady rest 60 includes a frame side member 61 attached to the upper horizontal frame 3 and a hinge side member 62 attached to the upper part of the hinge 20. One folding door device 60 is provided in the folding door device 1. However, the number is not necessarily one, and two or more may be provided.

  FIG. 14 shows a perspective view of the frame side member 61. The frame-side member 61 is a member having a trapezoidal shape in both a horizontal section and a vertical section, and has surfaces 61a and 61a as trapezoidal slopes in the horizontal section and a surface 61b as an upper base. A surface 61c is provided as a trapezoidal slope in the longitudinal section.

  FIG. 15 is a perspective view of the hinge side member 62. The hinge-side member 62 includes a contact portion 63, a vertical movement shaft 64 that is a shaft extending vertically downward from the lower surface of the contact portion 63, a cylindrical body 65 into which the vertical movement shaft 64 is inserted, and the cylindrical body. And a fixing portion 66 for fixing 65 to the hinge 20. The contact portion 63 is a part having a pentagonal horizontal cross section and a trapezoidal vertical cross section, and has 63a and 63a as slopes in the pentagon and 63c as slopes in the trapezoid. The vertical movement shaft 64 is inserted so as to be inserted into the cylindrical body 65 and is provided so as to move up and down. At this time, the vertical movement shaft is inserted into the cylinder together with an unillustrated elastic member, and is urged upward when the vertical movement shaft 64 is moved downward.

  The door steady rest 60 having such a configuration is arranged as shown in FIG. That is, the frame side member 61 is attached to the lower surface of the rail member 25 of the upper horizontal frame 3 in a portion where the door guide 26 is not provided. At this time, the surface 61c is directed downward, and the surfaces 61a and 61b are directed to the door guide 27 side. The hinge side member 62 is attached to the upper part of one of the hinges 20 that protrudes indoors in the folded posture of the doors 10, 10,. Then, with the deployed posture of the doors 10, 10,..., The frame side member 61 and the hinge side member 62 are arranged in the indoor / outdoor direction (the vertical direction in FIG. 12B) as shown in FIG. It arrange | positions so that it may become a positional relationship.

  Next, the operation of the door steady rest 60 will be described. FIG. 16 is a schematic plan view sequentially illustrating the operation of the door steady rest 60 when the doors 10, 10,... Are deployed from the folded posture. As shown in FIG. 16A, the hinge side member 62 attached to the hinge 20 approaches the frame side member 61 during the development process. When the unfolding operation is further continued, the surface 61a of the frame side member 61 and the surface 63a of the contact portion 63 of the hinge side member 62 come into contact with each other as shown in FIG. The contact portion 63 moves along the surface 61a of the frame side member 61 and reaches the surface 61b as shown in FIG. As a result, the contact portion 63, that is, the hinge side member 62, the hinge 20 to which the hinge side member 62 is attached, and the connecting portion of the doors 10 and 10 to which the hinge 20 is attached are restricted from moving indoors and outdoors. The so-called “rattle” of the door bodies 10, 10,... Is prevented.

  FIG. 17 shows a case where the frame side member 61 and the hinge side member 62 are not properly in contact with each other as shown in FIG. It is the figure of the vertical direction which showed typically the procedure which makes the frame side member 61 and the hinge side member 62 contact appropriately, and is set as the attitude | position shown in FIG.
