[0004] In an overhead door, an opening / closing body moves up and down, and the opening / closing body that moves to the upper part is held in a horizontal or inclined state. Therefore, in addition to guide members (guide rails, etc.) that guide the movement of the opening / closing body in the vertical direction, guide members (guide rails, etc.) that guide the movement of the opening / closing body in the depth direction are also provided. The guide member that guides movement in the depth direction is installed so that it is suspended from the ceiling (horizontal rail, frame, etc.) by a suspension member.

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be realized, and are not intended to limit the scope of the present invention.

[0019] <Embodiment 1> FIG. 1 is a perspective view showing an opening and closing device according to a first embodiment of the present invention, as viewed from the indoor side. The opening and closing device 100 of this embodiment is an opening and closing device that opens and closes an opening formed in a wall surface that separates the indoors and outdoors, and more specifically, is an opening and closing device called an overhead door or an over-sliding door. In the following, the vertical direction will be referred to as the "up-down direction," the width direction of the opening as the "width direction," and the direction perpendicular to these (direction from indoors to outdoors) as the "depth direction." In addition, in the width direction, the side that is left when looking from the outdoors toward the indoor side will be referred to as the left side, and the side that is right will be referred to as the right side. The outdoor side in the depth direction will be referred to as the entrance side, and the indoor side will be referred to as the back side.

[0020] The opening and closing device 100 is an opening / closing body 101 in which a plurality of panel bodies are rotatably connected to each other; a guide member 102 that guides the movement of the opening / closing body 101; and a side structure portion 104 which is a support portion for installing the guide member 102 and the like. A plurality of rollers 1011 are provided at both ends in the width direction of the opening / closing body 101, and the guide member 102 is composed of a guide rail that guides the movement of the rollers 1011. The guide rails include vertical rails 1023 (upper and lower guide members that guide the vertical movement of the opening and closing body) erected on both sides of the opening, horizontal rails 1021 that are installed near the ceiling and along the ceiling, and curved rails 1022 that connect the two. The vertical rail 1023 is fixed to the side structural part 104. The horizontal rail 1021 is fixed (welded) to the horizontal rail fixing frame 103, and the entrance side of the horizontal rail fixing frame 103 is fixed to the side structural part 104. The back side of the horizontal rail fixing frame 103 (and the horizontal rail 1021) is suspended and held from the ceiling (beam member, frame, etc.) by the hanging member 12 and the connecting member 11 (see Figure 2). The curved rail 1022 is fixed to both the side structural part 104 and the horizontal rail fixing frame 103. The opening and closing device 100 is also provided with a drive device and its mechanism for driving the opening and closing of the opening and closing body 101, a control device for controlling the opening and closing operation, and the like (not shown). Note that the present invention relates to a hanging member that suspends and holds a depth guide member that guides the movement of the opening / closing body in the depth direction, and a connecting member that connects the depth guide member and the hanging member, and any other configuration of the overhead door can be used, so further explanation will be omitted here. The "depth guide member" refers to a member (and members fixed thereto) that guides the movement of the opening / closing body in the depth direction, and in this embodiment, this corresponds to the horizontal rail 1021, the curved rail 1022, and the horizontal rail fixing frame 103.

[0021] FIG. 2 is a diagram showing a state in which the hanging members are attached to the depth guide members (horizontal rail 1021, curved rail 1022, horizontal rail fixing frame 103). In this embodiment, a hanging member 12 fixed to a ceiling (beam member, skeleton, etc.) is attached via a connecting member 11 near the rear end of the depth guide member. 2 shows the depth guide member on the left side, but the right side has a similar, symmetrical configuration. In the following explanation, the left side member will be described, and the right side, which has a symmetrical structure, will not be described.

[0022] 3 and 4 are diagrams showing the attached state of the hanging member 12 and the connecting member 11 of this embodiment, where Fig. 3(a) is a perspective view seen from the entrance side, Fig. 3(b) is a perspective view seen from the back side, Fig. 4(a) is a side view seen from the inside in the width direction (right side), Fig. 4(b) is a back view seen from the back side, and Fig. 4(c) is a side view seen from the outside in the width direction (left side). Note that Figs. 3 and 4 show the state in which the opening / closing body 101 is opened (the state in which the opening / closing body 101 has moved upward and is in a horizontal position). As shown in each figure, the hanging member 12 is An upper member 121 extending in the width direction and attached to a ceiling portion (a beam member in this embodiment) F; a vertical member 123 that extends in the vertical direction and is attached to the upper member 121 and the connecting member 11; A diagonal brace member 122 that forms a truss structure between the upper member 121 and the vertical member 123; Equipped with The upper member 121, the vertical member 123, and the diagonal member 122 are fastened to one another by bolts (bolts and nuts). Furthermore, the connection member 11 that connects the depth guide member and the hanging member 12 is also fastened to each member by bolts (bolts and nuts). The hanging member 12 (upper member 121) is attached to the beam member F by a one-sided bolt (crostite) OB (which is still a "bolt fastening" method).

[0023] 5A to 5C are diagrams showing the connection member 11, with FIG. 5A being a rear view, FIG. 5B being a side view, and FIG. 5C being a bottom view. The connecting member 11 is a single L-shaped member having a side surface portion 111 and a bottom surface portion 112, and in this embodiment, the thickness of the member is 3.2 mm. A hole 11h2, which is a hole (slot) through which a bolt for fastening the hanging member 12 (vertical member 123) is passed, is formed in the side portion 111 of the connecting member 11, approximately near the center thereof. Furthermore, a hole 11h1, which is a hole through which a drill screw DS is passed for fixing the hanging member 12 (vertical member 123) after the attachment angle has been determined, is formed above the hole 11h2. Here, the hole 11h1 through which the drill screw DS is passed is formed above the hole 11h2, as an example. However, the hole 11h1 through which the drill screw DS is passed may be formed below the hole 11h2, or may be formed both above and below the hole 11h2. Furthermore, the hole 11h1 may not be formed in advance, but may be drilled during construction using a drill screw DS or the like. A hole 11h3, which is a hole (slot) through which a bolt for fastening the depth guide member (the horizontal rail 1021 and the horizontal rail fixing frame 103) is passed, is formed near the bottom of the side surface portion 111 of the connecting member 11. In addition, a hole 11h4, which is a hole (slot) through which a bolt for fastening the depth guide member (the horizontal rail fixing frame 103) is passed, is also formed in the bottom surface portion 112. The horizontal rail fixing frame 103 of this embodiment is formed from an angle bar, and the side portion 111 and bottom portion 112 of the connecting member 11 are in contact with the two surfaces that make up the angle bar, and bolt fastening is performed on each surface. Here, the example is one in which bolts are fastened on both the side surface 111 and the bottom surface 112, but it is also possible to bolt on only one of the surfaces. Also, the example is one in which the connecting member 11 and the depth guide member (horizontal rail fixing frame 103) are in contact on two surfaces, but they may also be in contact on one surface (or may be in contact on three surfaces).

[0024] The holes 11h2 through which the bolts that fasten the hanging member 12 (vertical member 123) are inserted are elongated holes that extend in the vertical direction, which allows adjustment of the vertical position of the bolt fastening to the hanging member 12 (vertical member 123). In other words, the holes 11h2 and the bolts constitute a "vertical adjustment structure that adjusts the vertical attachment position of the hanging member relative to the depth guide member." As can be seen from FIG. 9(c), the bolt fastening allows the attachment angle of the hanging member relative to the depth guide member to be adjusted (angle adjustment by bolting the up / down adjustment structure) using the bolt as an axis. In other words, it is provided with an "angle adjustment structure that adjusts the attachment angle of the hanging member relative to the depth guide member." In this embodiment, a horizontal rail 1021 is used as an example of a member for guiding the opening / closing body to move in the depth direction, but some devices have an inclined rail that inclines and guides the opening / closing body that moves upward. The ability to adjust the angle allows for flexible adaptation to inclined rails, etc. Furthermore, holes 11h3 and 11h4 through which bolts that fasten the depth guide member are inserted are elongated holes that extend in the depth direction, making it possible to adjust the depth direction position of the bolt fastening relative to the depth guide member. In other words, it is provided with a "depth adjustment structure that adjusts the depth direction attachment position of the hanging member relative to the depth guide member."

[0025] 6A to 6C are diagrams showing the upper member 121, with FIG. 6A being a side view, FIG. 6B being a top view, and FIG. 6C being a rear view. The upper member 121 is formed from an angle iron, has a first surface 1211 and a second surface 1212, and has a plate thickness of 3.2 mm in this embodiment. The first surface 1211 (see FIG. 6(c)) has: A hole 1211L3 for bolting the vertical member 123 and a plurality of holes 1211L2 for selectively bolting the diagonal member 122, which are used when attaching to the left depth guide member (for installation on one side in the width direction); Holes 1211R1 (two in this embodiment) for bolting to the beam member F (ceiling part) used when attaching to the right depth guide member (for installation on the other side in the width direction), is formed. The second surface 1212 (see FIG. 6(b)) has: A hole 1212R3 for bolting the vertical member 123 and a plurality of holes 1212R2 for selectively bolting the diagonal member 122, which are used when attaching to the right-side depth guide member (for installation on the other side in the width direction); Holes 1212L1 (two in this embodiment) for bolting to the beam member F (ceiling) used when attaching to the left depth guide member (for installation on one side in the width direction), is formed. The upper member 121 is made of angle iron, which gives it strength, and since the above-mentioned holes are formed on each surface (first surface 1211, second surface 1212) that makes up the angle iron, it can be installed on either the left or right side with just one part. Holes 1211R4 and 1212L4 are holes for passing screws to temporarily fix the upper member 121 to the beam member F (ceiling portion). After temporarily fixing the upper member 121 with temporary fixing screws (drill screws, etc.), the upper member 121 can be attached to the beam member F (ceiling portion) with one-sided bolts OB, which provides excellent workability (construction can be done by one person).

[0026] Holes 1212L1 and 1211R1 through which bolts are passed to fasten to beam member F (ceiling portion) are elongated holes extending in the width direction, which allows adjustment of the widthwise position of the bolt fastening to beam member F (ceiling portion). In other words, holes 1212L1 and 1211R1 and the bolts form a "width adjustment structure that adjusts the widthwise attachment position relative to the ceiling portion." In this example, two elongated holes for bolting the beam member F (ceiling portion) are formed on each of the first surface 1211 and the second surface 1212 of the upper member 121, but the present invention is not limited to this, and one elongated hole may be formed on either surface (or both surfaces), or three or more elongated holes may be formed.

[0027] 7A to 7C are diagrams showing the vertical member 123, with FIG. 7A being a top view, FIG. 7B being a side view, and FIG. 7C being a rear view. The vertical member 123 is formed from an angle iron, has a first surface 1231 and a second surface 1232, and has a plate thickness of 4.5 mm in this embodiment. The first surface 1231 (see FIG. 7(c)) has: A plurality of holes 1231L1 for selectively bolting the upper member 121 formed on one side (left side in FIG. 7(c)) of the longitudinal center of the vertical member 123, which are used when attaching to the left depth guide member (for installation on one side in the width direction), and holes 1231L2 for bolting the diagonal brace member 122 formed on the other side (right side in FIG. 7(c)) of the longitudinal center of the vertical member 123, A plurality of holes 1231R1 for selectively bolting the upper member 121 formed on the other side (the right side in FIG. 7(c)) of the longitudinal center of the vertical member 123, which are used when attaching to the right depth guide member (for installation on the other side in the width direction), and holes 1231R2 for bolting the diagonal brace member 122 formed on one side (the left side in FIG. 7(c)) of the longitudinal center of the vertical member 123, is formed. The second surface 1232 (see FIG. 7(b)) has: A hole 1232L3 for bolting the connecting member 11 formed on the other side (the right side in FIG. 7(b)) of the longitudinal center of the vertical member 123, which is used when attaching to the left depth guide member (for installation on one side in the width direction); A hole 1232R3 for bolting the connecting member 11 formed on one side (the left side in FIG. 7(b)) of the longitudinal center of the vertical member 123, which is used when attaching to the right depth guide member (for installation on the other side in the width direction); is formed. The vertical member 123 is made of angle iron, which gives it strength, and since the above-mentioned holes are formed on each surface (first surface 1231, second surface 1232) that makes up the angle iron, it can be installed on either the left or right side with just one part.

[0028] The formation of a plurality of holes 1231L1, 1231R1 for bolting the upper member 121 makes it possible to adjust the fastening position (height) of the vertical member 123 relative to the upper member 121. As described above, the connecting member 11 can also be used to adjust the mounting position in the vertical direction, but the "multiple holes for selectively bolting the upper member" of the vertical member 123 make it possible to adjust the mounting position in the vertical direction over a wider range. By determining the mounting position relative to the upper member 121 by selecting holes 1231L1 and 1231R1, it is possible to roughly determine the position in the vertical direction (within a wider setting range), and then use the connecting member 11 to determine the position more accurately.

[0029] 8A to 8C are diagrams showing the diagonal brace member 122, with FIG. 8A being a side view, FIG. 8B being a top view, and FIG. 8C being a bottom view. The diagonal brace member 122 is formed from an angle bar, has a first surface 1221 and a second surface 1222, and has a plate thickness of 3.2 mm in this embodiment. The first surface 1221 (see FIG. 8(c)) has: A hole 1221R1 is formed in the right-hand depth guide member to fasten the vertical member 123 with a bolt (for installation on the other side in the width direction). The second surface 1222 (see FIG. 8(b)) has: A hole 1222L1 is formed in the vertical member 123 for bolting, which is used when attaching the vertical member 123 to the left depth guide member (for installation on one side in the width direction). One end of the diagonal brace 122 is connected to the vertical member 123, and the other end is connected to the upper member 121, but the holes for bolting the upper member 121 are not shown because they are formed at the assembly site. From the standpoint of strength, it is desirable to attach the diagonal brace 122 at a 45° angle to the vertical member 123 and the upper member 121, and therefore, to make it easier to adjust the dimensions at the site (the diagonal brace can be adjusted (cut) to the appropriate length at the site), the holes for bolting the upper member 121 are formed at the assembly site. Here, it is explained that holes 1222L1 and 1221R1 are holes for fastening vertical member 123, but holes 1222L1 and 1221R1 may also be holes for fastening upper member 121 (holes for vertical member 123 may be drilled on-site).

[0030] 9A and 9B are diagrams showing the hanging member 12 and the connecting member 11 of this embodiment, where FIGS. 9A and 9B are views similar to FIGS. 3A and 3B, and FIG. 9C is a side view. As explained above, The formation of multiple holes 1231L1 for bolting the upper member 121 allows for adjustment of the vertical position, and the formation of long holes 11h2 in the connecting member 11 that extend in the vertical direction allows for adjustment of the vertical position of the bolt fastening to the hanging member 12 (vertical member 123). At this time, the formation of multiple holes 1211L2 in the upper member 121 for bolting the diagonal brace members 122 also allows for appropriate changes to the attachment positions of the diagonal brace members in accordance with changes in the vertical position. Furthermore, when the connecting member 11 and the vertical member 123 are bolted together, the bolt can be used as an axis to adjust the attachment angle of the hanging member relative to the depth guide member (angle adjustment by bolting the up / down adjustment structure) (see Figure 9(c)). Furthermore, in the connection member 11, the holes 11h3 and 11h4 are elongated holes extending in the depth direction, so that the position in the depth direction where the bolt is fastened to the depth guide member can be adjusted. Additionally, in the upper member 121, the hole 1212L1 is an elongated hole extending in the width direction, so that the position of the bolt fastened to the beam member F (ceiling portion) in the width direction can be adjusted. As can be seen from the above, it is possible to easily fine-tune the positional relationship between the components during construction, thereby enabling accurate positioning of the components.

[0031] When fastening the connecting member 11 and the hanging member 12 (vertical member 123), once the rotation angle around the bolt that fastens them and the height position of both are determined, the two are fixed together by drilling a hole in the vertical member 123 with a drill screw DS and screwing it in. This makes it possible to prevent the angle and height from changing due to loosening of the bolt (nut). Here, the example is one in which a hole 11h2 for passing the drill screw DS through is formed in advance in the connecting member 11, and the drill screw DS is screwed in while drilling a hole in the vertical member 123, but it is also possible to form a hole in the vertical member 123 in advance, and then screw in the drill screw DS while drilling a hole in the connecting member 11. Furthermore, between the connecting member 11 and the depth guide member, or between the upper member 121 and the ceiling, after the installation position has been determined, the position may be fixed using a drill screw (to prevent the position from changing due to loosening of the bolt (nut)).

[0032] As described above, according to the opening and closing device 100 of this embodiment, in the structure in which the guide members are attached by the hanging members, welding is not required, and it is possible to easily and accurately adjust the positions of the members during construction. Furthermore, the connecting member 11, the upper member 121, the diagonal brace member 122, and the vertical member 123 can all be used for both the left and right sides, which allows for a reduction in the number of parts (and therefore a reduction in costs).

[0033] In this embodiment, the hanging member 12 is attached in a direction that fits inside in the width direction, but the hanging member 12 can also be attached in a direction that faces outward in the width direction. In this case, since the "common parts are used on the left and right sides" as explained above, it is possible to accommodate either case without requiring any new parts.

[0034] <Embodiment 2> 10 and 11 are diagrams showing the attached state of the hanging members and connecting members provided in the opening and closing device of embodiment 2, with Fig. 10 being a perspective view, Fig. 11(a) being a side view seen from the inside in the width direction (right side), Fig. 11(b) being a rear view seen from the back side, and Fig. 11(c) being a side view seen from the outside in the width direction (left side). Note that Fig. 11(b) shows the state in which the opening and closing body 101 is opened (the state in which the opening and closing body 101 has moved upward and is in a horizontal position). The opening and closing device of embodiment 2 differs from embodiment 1 in the hanging member 13, but other configurations are the same as embodiment 1, so the explanation of the similar configurations will be simplified or omitted here (the same symbols as embodiment 1 are used for the similar configurations as embodiment 1).

[0035] As shown in the drawings, the hanging member 13 of this embodiment is An upper member 131 attached to a ceiling portion (a beam member in this embodiment) F; a vertical member 132 that extends in the vertical direction and is attached to the upper member 131 and the connecting member 11; Equipped with The upper member 131 and the vertical member 132 are fastened to each other by bolts (bolts and nuts).

[0036] 12A to 12C are diagrams showing the upper member 131, with FIG. 12A being a side view, FIG. 12B being a front view, and FIG. 12C being a bottom view. The upper member 131 is a single L-shaped member having a side portion 1312 and an upper portion 1311, and in this embodiment has a thickness of 4.5 mm (i.e., a thickness thicker than the upper member 121 and connecting member 11 of embodiment 1 (both 3.2 mm)). The upper surface portion 1311 (see FIG. 12(c)) is formed with holes 13111 for bolting to the beam member F (ceiling portion). The side surface 1312 (see FIG. 12(b)) has: A hole 1312L2 (two holes in this embodiment) for bolting the vertical member 132, which is used when attaching to the left depth guide member (for installation on one side in the width direction), A hole 1312R2 (two holes in this embodiment) for bolting the vertical member 132, which is used when attaching to the right depth guide member (for installation on the other side in the width direction), is formed. The holes 13113 are holes for passing screws to temporarily fix the upper member 131 to the beam member F (ceiling portion), and are similar to the holes 1211R4 and 1212L4 of the upper member 121 of the first embodiment.

[0037] The holes 13111 through which the bolts are inserted to fasten the beam member F (ceiling portion) are elongated holes extending in the width direction, which allows the widthwise position of the bolt fastening to the beam member F (ceiling portion) to be adjusted. In other words, the holes 13111 and the bolts form a "width adjustment structure that adjusts the widthwise attachment position relative to the ceiling portion." Here, an example is given in which one elongated hole for bolt fastening is formed in the beam member F (ceiling portion), but the present invention is not limited to this, and two or more elongated holes may be formed.

[0038] 13A, 13B, and 13C are diagrams showing the vertical member 132, with FIG. 13A being a top view, FIG. 13B being a side view, and FIG. 13C being a rear view. The vertical member 132 is formed from an angle member, has a first surface 1321 and a second surface 1322, and has a thickness of 4.5 mm in this embodiment (that is, a thickness thicker than that of the connecting member 11 (3.2 mm)). The first surface 1321 (see FIG. 13(b)) has: a hole 1321L2 for bolting the connecting member 11 formed on one side (the right side in FIG. 13(b)) of the longitudinal center of the vertical member 132, which is used when attaching to the left depth guide member (for installation on one side in the width direction); a hole 1321R2 for bolting the connecting member 11 formed on the other side (left side in FIG. 13(b)) of the longitudinal center of the vertical member 132, which is used when attaching to the right depth guide member (for installation on the other side in the width direction); is formed. The second surface 1322 (see FIG. 13(c)) has: A hole 1322L1 (two holes in this embodiment) for bolting the upper member 131 formed on the other side (left side in FIG. 13(c)) of the longitudinal center of the vertical member 132, which is used when attaching to the left depth guide member (for installation on one side in the width direction); A hole 1322R1 (two holes in this embodiment) for bolting the upper member 131 formed on one side (the right side in FIG. 13(c)) of the longitudinal center of the vertical member 132, which is used when attaching to the right depth guide member (for installation on the other side in the width direction); is formed. The vertical member 132 is made of angle iron, which gives it strength, and since the above-mentioned holes are formed on each surface (first surface 1321, second surface 1322) that makes up the angle iron, it can be installed on either the left or right side with just one part.

[0039] The connecting member 11 is the same as that in embodiment 1, and is provided with a "vertical adjustment structure," an "angle adjustment structure," and a "depth adjustment structure" as in embodiment 1. The connecting member 11 is fastened to the hanging member 13 by bolting.

[0040] The hanging member 12 of embodiment 1 has a truss structure formed by the upper member 121, the diagonal brace member 122, and the vertical member 123, and is therefore strong, but may not be usable in cases where the space (headroom) near the ceiling is small. As can be seen from FIG. 11(b), when the distance to the beam member F (ceiling portion) is short, there is no space to provide bracing (because it would interfere with the opening / closing body 101, etc.). In such a case, the hanging member 13 of the second embodiment has the same function as that of the first embodiment, and can be used even when the space (headroom) near the ceiling is small.

[0041] Hanging member 13 does not have any diagonal bracing members or a truss structure, but instead has a structure in which upper member 131 is a thick member and is fastened to vertical member 132 of the same thickness with two bolts. This gives hanging member 13 the same strength as hanging member 12. Although the upper member 131 and the vertical member 132 are fastened together with two bolts in this example, they may be fastened together with three or more bolts.

[0042] As described above, the opening and closing device of this embodiment can be installed even when the space (headroom) near the ceiling is small, and the same effects as those of the first embodiment can be obtained.

[0043] In the above embodiment, an example is given in which the horizontal rail (and curved rail) is reinforced and fixed using a horizontal rail fixing frame, but the present invention is not limited to this, and it is also possible to have a structure without a horizontal rail fixing frame (a structure in which a connecting member is attached to the horizontal rail).

[0044] In the above embodiment, the hanging member (and connecting member) is provided at one location on the rear side of the depth guide member, but the present invention is not limited to this, and the depth guide member may be attached by multiple hanging members (and connecting members) (such as hanging members (and connecting members) provided at predetermined intervals). Also, the curved rail may be suspended by hanging members (and connecting members).

[0045] In the above embodiment, the connecting member is exemplified as having up / down adjustment function, angle adjustment function, and depth adjustment function, but it may have only one of these functions or any combination of these functions. The connecting member (or the horizontal rail fixing frame) may also be given a widthwise adjustment function. This can be achieved by making the hole 11h4 in the bottom surface 112 of the connecting member 11 an elongated hole extending in the widthwise direction. Alternatively, by providing an elongated hole extending in the widthwise direction in the horizontal rail fixing frame opposite the hole 11h4 in the bottom surface 112 of the connecting member 11, the horizontal rail fixing frame can be given a widthwise adjustment function while maintaining the depth adjustment function of the connecting member 11. In these cases, the hole 11h3 in the side surface 111 of the connecting member 11 is unnecessary (cannot be used), or a fastening method that can accommodate widthwise displacement (such as attaching a spacer or using a separate nut) is required.
