Summary of the Invention

Problem to be Solved by the Invention

[0004] Buildings generally have a foundation, on which columns and other structural elements are constructed, and then walls and other finishes are added. Shutter systems are typically installed after the columns and other structural elements have been erected on the foundation, but before the walls and other finishes are completed (this is called pre-installation). In this case, there is a step between the foundation and the columns, and when installing the shutter system, it is necessary to either cut out a portion of the guide rail using fire, for example, with a cutting machine such as a grinder, or coordinate with the site beforehand to ensure that there is no step between the foundation and the columns only where the guide rail will be installed. Processing using fire poses risks such as fire, as well as potential quality degradation due to the work being done by the worker, including poor finish and even rust. Furthermore, if the building is designed to have no steps from the start, it creates constraints such as the inability to make adjustments or revert (returning to the state before the step was eliminated). In addition, in the case of existing sites, it is practically difficult to cut away the step when replacing the guide rail, as this would weaken the foundation.

[0005] This invention was made in view of the above circumstances, and its purpose is to provide an opening / closing mechanism that can be attached to a building structure without fire, without cutting out a guide rail that rises vertically from the floor surface, even if there is a step between the foundation and the building structure, thereby suppressing a deterioration in quality. Guide rail The objective is to provide. [Means for solving the problem]

[0006] Next, means for solving the above-mentioned problems will be described with reference to drawings corresponding to the embodiments. For opening and closing body according to claim 1 of the present invention Guide rail 11 This is an opening / closing mechanism that is attached to a pair of vertically extending structural members 25 located at both ends in the width direction of the opening 15 of a building, and guides the edges on both sides in the width direction of the opening / closing mechanism 19 that opens and closes the opening 15. Guide rail And, The frame 25 is placed on the foundation 47 with a step 49, where the lower surface of the smaller side of the foundation 47, which rises from the floor surface 23, rests on the foundation 47. ,lower endA fixing frame 51 that rests on the step 49 and is fixed to the inner surface 26 of the opening and to one of the indoor or outdoor surfaces of the building structure 25, a support frame 59 that is attached to a guide rail 57 with the same length, whose lower end reaches the floor surface 23 and is fixed to the fixing frame 51, a foundation opening side fixing member 61 that is fixed to the inner surface 67 of the opening of the foundation 47, and a foundation connecting member 63 that fixes the support frame 59 and the foundation opening side fixing member 61, It is characterized by having the following features.

[0007] For this opening and closing mechanism Guide rail 11 The structural frame 25 then rests on the upper surface 48 of the foundation 47, which rises from the floor surface 23. The structural frame 25 is placed on the foundation 47 with a step 49, as the lower surface of the smaller side of the foundation 47 rests on the upper surface 48. Each guide rail 57 that guides the edges on both sides in the width direction of the opening / closing body 19 is positioned at both ends in the width direction of the opening 15, with its lower end reaching the floor surface 23 and extending vertically. The guide rail 11 for the opening / closing body, which is used to fix the guide rail 57 to the building, includes a fixing frame 51, a support frame 59, a foundation opening side fixing member 61, and a foundation connecting member 63. The fixing frame 51 is fixed to the inner surface 26 of the opening and to one of the indoor or outdoor sides (front 27) of the building structure 25, with a portion of its lower end resting on the upper surface 48 of the foundation 47. In other words, the fixing frame 51 is fixed to the building structure 25 above the step difference 49 between the building structure 25 and the foundation 47. The support frame 59 is attached to the guide rail 57, whose lower end reaches the floor surface 23, with the same length. The support frame 59, like the guide rail 57, stands upright along the foundation 47 and the building structure 25. The support frame 59 above the step 49 is fixed to a fixing frame 51 which is fixed to the building structure 25. As a result, the guide rail 57 above the step 49 is firmly fixed to the building structure 25 via the fixing frame 51 and the support frame 59. On the other hand, the support frame 59 has a foundation connecting member 63 fixed to the portion of the foundation 47 below the step 49 where the fixing frame 51 is absent. A foundation opening side fixing member 61 is fixed to the portion of the foundation 47 corresponding to this foundation connecting member 63. The lower part of the support frame 59 is firmly fixed to the foundation 47 by fastening these foundation connecting members 63 and foundation opening side fixing member 61 together. For this opening and closing mechanism Guide rail 11 As a result, the guide rail 57 can be fixed to the structure 25 by the fixing frame 51 and the support frame 59 without interfering with the foundation 47. Thus, for opening and closing mechanisms Guide rail 11 Therefore, the guide rail 57 and the support frame 59 fixed to the guide rail 57 are attached to the building with nearly identical cross-sections at any point along their longitudinal direction, without being cut out to avoid interference with the foundation 47. As a result, the work of cutting out a portion of the guide rail 57 with fire becomes unnecessary. Furthermore, the guide rail 57 does not suffer a reduction in strength due to the notch provided to avoid the foundation 47. In addition, the complicated construction management required by the building side, which involves coordinating with the site in advance to ensure that there is no step 49 between the foundation 47 and the column only where the guide rail 57 is to be installed, is not necessary. In addition, since no fire processing is performed, fire prevention measures are unnecessary. Furthermore, poor finishes and rust are less likely to occur, resulting in a better appearance and increased durability. Moreover, when replacing guide rails 57 at an existing site, there is no need to cut away the step 49, so new guide rails 57 can be installed without reducing the strength of the foundation 47.

[0008] For opening and closing body according to claim 2 of the present invention Guide rail 11 This is for the opening and closing mechanism described in claim 1. Guide rail And, The upper surface 48 of the foundation 47 protrudes horizontally from one of the faces of the building structure 25. The fixing frame 51 is characterized in that it fixes the guide rail 57 to the structure 25 with a clearance K that is larger than the overhang E of the foundation 47 from one of the surfaces.

[0009] For this opening and closing mechanism Guide rail 11Then, the guide rail 57 is fixed to the structure 25 by the fixing frame 51 and the support frame 59 with a clearance K that is larger than the overhang E of the foundation 47. Therefore, the guide rail 57 can be firmly fixed to the structure 25 in the vertical direction without interfering with the foundation 47. The lower end of the fixing frame 51 rests on the step 49, so it is absent below the step 49. The support frame 59 is fixed to the part of the foundation 47 where the fixing frame 51 is absent below the step 49, and the foundation connecting member 63 is fixed to it. The foundation connecting member 63 is fixed to the foundation opening side fixing member 61 which is fixed to the foundation 47. Therefore, for opening and closing Guide rail 11 As a result, the lower part of the support frame 59, where the fixed frame 51 is absent, is firmly fixed to the foundation 47 by the foundation connecting member 63 and the foundation opening side fixing member 61, thereby supporting the vertical position of the guide rail 57.

[0010] For opening and closing body according to claim 3 of the present invention Guide rail 11 The opening / closing body according to claim 1 or 2 Guide rail And, A cover plate 105 that closes the gap S between the indoor or outdoor side of the foundation 47 and the guide rail 57 is fixed to the foundation 47.

[0011] For this opening and closing mechanism Guide rail 11 Next, a support frame 59 of the same length is attached to and fixed to the guide rail 57. This support frame 59 is fixed to a fixing frame 51 attached to the building structure 25. The fixing frame 51 fixes the support frame 59 and the guide rail 57 to the building structure 25 with a clearance K that is larger than the overhang E of the foundation 47. In other words, a gap S is created between the support frame 59 attached to the guide rail 57 and the foundation 47. This gap S does not occur above the step 49 because the fixing frame 51 and the support frame 59 are fixed together. On the other hand, the fixing frame 51 is absent from the foundation 47 below the step 49, so only the support frame 59 is positioned along the foundation 47. Since the guide rail 57 is spaced apart from the building structure 25 with a clearance K that is larger than the overhang E of the foundation 47, a gap S is created between the guide rail 57 and the building structure 25. For opening and closing mechanism Guide rail 11 This gap S will then be closed by the cover plate 105 which will be fixed to the foundation 47.

[0012] The opening / closing body for opening / closing body according to claim 4 of the present invention Guide rail 11 is the opening / closing body for opening / closing body according to claim 1 or 2 Guide rail , wherein it comprises a housing frame 65 formed of a refractory material, which is detachably fixed to a side surface of the guide rail 57 opposite to the support frame 59 to cover said side surface, and a signal generating device connected to an opening / closing machine 39 that drives opening and closing of said opening / closing body 19 via a signal transmission member inserted into an inner space 111 and facing said opening 15 at a predetermined height position from a floor surface 23 is attached to said housing frame 65, wherein a stepped portion 113 that is recessed inward in a concave shape and to which said signal generating device is attached is formed in a part of said housing frame 65 facing said opening 15.

[0013] In this opening / closing body for opening / closing body Guide rail 11 , the other side surface of the guide rail 57 is covered by the housing frame 65 formed of a refractory material, for example steel, so that compared to a configuration in which a non-refractory material such as aluminum is used for the housing frame 65, the influence of flame and the like on the guide rail 57 can be suppressed during a fire. That is, the guide rail 11 for an opening / closing body can improve strength (fire resistance) when exposed to flame. Furthermore, for the housing frame 65 fixed to cover the other side surface of the guide rail 57, the inner space 111 can be used as an insertion space for the signal transmission member, so that the signal generating device attached to the surface of the housing frame 65 facing the opening 15 (the housing front piece 121) can be connected to the opening / closing machine 39 by easy construction using the space 111 of the housing frame 65. In the housing frame 65, the stepped portion 113 that is recessed inward in a concave shape and to which the signal generating device is attached is formed in a part of the housing front piece 121 facing the opening 15. The stepped portion 113 is formed into a recessed state relative to the housing front piece 121 by bending the housing front piece 121 stepwise toward the space 111. That is, the stepped portion 113 forms a vertical groove recessed along the guide rail 57 between the guide rail 57 and the housing front piece 121. The housing portion 115 is attached by inserting a part of the signal generating device into a notch formed in the groove bottom surface of the stepped portion 113. opening / closing body for opening / closing body Guide rail 11 Since the stepped portion 113 is formed in the housing portion 115 and the cutout portion only needs to be formed in the stepped portion 113, it is no longer necessary to align the cutout portion with the cutout portion formed in the cover 117. This simplifies alignment and facilitates easy installation. In addition, misalignment is eliminated, and the signal generating device can be installed accurately, so there is no risk of impairing design properties. Furthermore, since the cutout portion is provided on the groove bottom surface of the stepped portion 113, the finished structure of the mounting portion is not conspicuous, and the edge of the steel sheet used as the material of the cover 117 is not exposed either, which also enables excellent design properties to be obtained.

[0014] The opening / closing body for opening / closing device according to claim 5 of the present invention Guide rail 11 is the opening / closing body for opening / closing device according to claim 3 Guide rail , wherein there is provided a housing frame 65 which is formed of a refractory material, is detachably fixed to a side surface of the guide rail 57 that is opposite to the support frame 59, covers the side surface, is connected to an opening / closing machine 39 that drives the opening / closing body 19 to open and close via a signal transmission member inserted into the inner space 111, and has a signal generating device facing the opening 15 at a predetermined height position from the floor surface 23 attached thereto, the housing frame 65 is characterized in that a stepped portion recessed inwardly in a concave shape, to which the signal generating device is attached, is formed in a part of the housing frame 65 facing the opening 15.

[0015] In this opening / closing body for opening / closing device Guide rail 11 , the operation is the same as that of claim 4. [Effects of the Invention]

[0016] According to the opening / closing body for opening / closing device according to claim 1 of the present invention Guide rail , even if there is a level difference between the foundation and the frame body, processing such as cutting out the guide rail that stands vertically from the floor surface is unnecessary, and the device can be attached to the frame body without hot work. In addition, since no cutting is performed, deterioration in quality can be suppressed.

[0017] The opening / closing body for opening / closing device according to claim 2 of the present invention Guide railAccording to this, the guide rail can be installed with a clearance larger than the overhang of the foundation, spaced apart from one side of the structure, and the guide rail can be fixed vertically upright from the floor surface while avoiding the foundation without cutting out the guide rail.

[0018] For opening and closing body according to claim 3 of the present invention Guide rail According to this, the gap that arises when a fixed frame is absent on one side of the foundation can be covered by a cover plate installed across the guide rail and the foundation, for opening and closing mechanism Guide rail This can suppress quality degradation in that regard.

[0019] For opening and closing body according to claim 4 of the present invention Guide rail According to this design, the other side of the guide rail is covered by a housing frame made of fire-resistant material. This enhances the fire resistance of the guide rail by covering it with fire-resistant material, and also allows for the insertion of signal transmission members using the internal space, facilitating the attachment of signal generating equipment to the housing frame. Furthermore, the stepped section prevents the edges of the housing frame from being exposed, resulting in a more aesthetically pleasing design.

[0020] For opening and closing body according to claim 5 of the present invention Guide rail According to this, the same effect as claim 4 can be obtained. [Brief explanation of the drawing]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows the opening / closing mechanism according to this embodiment. Guide rail 11 This is a front view of a shutter device 13 equipped with the shutter device. For opening and closing mechanisms according to this embodiment Guide rail 11 This can be suitably used in shutter devices 13 that open and close building openings 15 using an opening / closing mechanism, such as shutter devices 13 installed in garages. The opening / closing mechanism can be a general shutter curtain 19 made of multiple connected steel slats 17, a curtain made of connected panel materials or pipes, or a resin sheet-like curtain. The shutter curtain 19 closes the opening 15 when the base plate 21 sits on the floor surface 23.

[0023] For opening and closing mechanisms Guide rail 11 This refers to a pair of vertically extending structural elements 25 (see Figure 2) positioned at both ends in the width direction of the building's opening 15. Take It can be attached. In this embodiment, the frame 25 is a wooden frame. The wooden frame can be, for example, a column in a wooden frame construction method. The column has a rectangular cross-sectional shape perpendicular to the longitudinal direction. However, the frame 25 is not limited to a column. The frame 25 may be a panel with a core material used in a wooden panel construction method.

[0024] The guide rail 11 for opening and closing is fixed to one of the indoor or outdoor surfaces of the building structure 25. In this embodiment, the one surface is the indoor surface. Hereinafter, the indoor surface will also be referred to as the front surface 27 (see Figure 2). The guide rail 11 for opening and closing is attached to the respective front surfaces 27 of the pair of left and right surfaces of the building structure 25 that sandwich the opening 15. The guide rail 11 for opening and closing guides the edges on both sides in the width direction of the shutter curtain 19 that opens and closes the opening 15.

[0025] In this embodiment, the shutter device 13 is described as being installed in a building such as a house or a garage adjacent to a house. The shutter device 13 is assembled so that a shutter storage section 31 is stretched across a pair of left and right brackets 29 fixed above the opening. The shutter storage section 31 houses a winding shaft 35 that is rotatable around one shaft 33 supported by the bracket 29 and winds up the shutter curtain 19, an opening / closing mechanism 39 that rotates the other shaft head 37 of the winding shaft 35 to rotate the winding shaft 35 in forward and reverse directions, and a control unit 41 that drives and controls the opening / closing mechanism 39. The opening / closing mechanism 39 is connected to the control unit 41 and is also connected to a signal generating device by a signal transmission member, which will be described later.

[0026] The signal generating equipment and signal transmission members are provided in the housing frame 65, described later, which constitutes the guide rail 11 for the opening and closing body. The signal generating equipment includes a manual switching device 43 (see Figure 3) that sends a manual switching signal to the opening and closing mechanism 39, and an obstacle detection sensor 45 (see Figure 3) that sends an electrical opening and closing body stop signal to the control unit 41. The signal transmission members include a wire (not shown) that transmits the manual switching signal from the manual switching device 43 to the opening and closing mechanism 39, and a signal wire (not shown) that transmits an electrical opening and closing body stop signal from the obstacle detection sensor 45 to the control unit 41.

[0027] The opening / closing mechanism 39 drives the winding shaft 35 by adjusting the rotational speed and torque of the electric motor using a gear mechanism. The rotation of the electric motor is transmitted to the winding shaft 35 via a chain and sprocket. The opening / closing mechanism 39 is connected by a signal generating device (manual switching device 43) via a signal transmission member (wire) to allow the shutter curtain 19 to be opened and closed manually by pulling the operating part, thereby cutting the power transmission path between the electric motor and the winding shaft 35. The mechanism for cutting the power transmission path is composed of a clutch mechanism or the like.

[0028] Figure 2 shows the opening / closing mechanism. Guide rail 11 This is a decomposed perspective view of the area. The building's foundation 47 rises from the floor surface 23 at a predetermined height. The foundation 47 is, for example, a strip foundation. The height of the foundation 47 can be approximately 300 to 500 mm. The lower surface of the structural frame 25 rests on the upper surface 48 of the foundation 47. The structural frame 25 is placed on the foundation 47 with a step 49, as the lower surface of a side smaller than the upper surface 48 of the foundation 47 rests on the foundation 47.

[0029] The guide rail 11 for opening and closing includes a fixed frame 51, a structural opening inner surface fitting 53, a structural front fitting 55, a guide rail 57, a support frame 59, a foundation opening side fixing member 61, a foundation connecting member 63, and a housing frame 65.

[0030] The fixing frame 51 has its lower end resting on the upper surface 48 of the foundation 47, extends upward from the step 49, and is fixed to the inner surface 26 of the opening and the front surface 27 of the building structure 25. The fixing frame 51 is made of a fire-resistant material, such as steel. The fixing frame 51 has a front piece 71 and a rear piece 73 of the fixing frame bent at right angles on the side of the opening 15 of the fixing frame body 69 parallel to the front surface 27 of the building structure 25 and on the opposite side, forming a roughly U-shape in plan view perpendicular to the longitudinal direction. A fixing frame engaging piece 75 is formed at the bent tip of the fixing frame rear piece 73, which is bent parallel to the fixing frame rear piece 73 and protrudes toward the fixing frame body 69.

[0031] The structural opening inner surface fitting 53 is an L-shaped fitting. The structural opening inner surface fitting 53 fixes the fixing frame 51 to the inner surface 26 of the opening in the structural frame 25. Multiple structural opening inner surface fittings 53 may be provided along the fixing frame 51 at predetermined pitches as shown in the figure, or they may be long angle members or the like, the same length as the fixing frame 51.

[0032] The structural frame front fitting 55 is an L-shaped fitting. The structural frame front fitting 55 fixes the front 27 to the rear piece 73 of the fixing frame. Multiple structural frame front fittings 55 may be provided along the fixing frame 51 at predetermined pitches as shown in the figure, and they may also be long angle members or the like, the same length as the fixing frame 51.

[0033] Furthermore, these structural opening inner fittings 53 and structural front fittings 55 may each be configured in multiple units at predetermined intervals, or one may consist of multiple units while the other consists of long angle materials.

[0034] The inner surface fitting 53 for the structural opening and the front surface fitting 55 for the structural opening are fixed to the structural frame 25 with coarse thread screws 77. The coarse thread screws 77 are almost the same shape as wood screws and do not require pilot holes. In addition, the inner surface fitting 53 for the structural opening and the front surface fitting 55 for the structural opening are fixed to the fixing frame 51 with self-tapping screws 79. Self-tapping screws 79 are also called drill screws and do not require pilot holes.

[0035] Furthermore, the fixing frame 51 may be designed to integrally include the same shaped parts as the structural opening inner fitting 53 and the structural front fitting 55. In this case, the separate structural opening inner fitting 53 and structural front fitting 55 can be eliminated.

[0036] Figure 3 is a cross-sectional view of AA in Figure 1. The guide rail 57 is covered on one side by a support frame 59. The guide rail 57 is formed from a fire-resistant material such as steel and has a roughly U-shaped cross-section, and also has an aluminum retaining rail section 83 into which a wind-resistant hook 81 (see Figure 1) provided on the shutter curtain 19 engages. The guide rail 57 has a length such that its upper end reaches the shutter storage section 31 and its lower end reaches the floor surface 23. The lower end of the guide rail 57 may be embedded below the floor surface 23. This allows the guide rail 57 to be fixed more securely. In this case, the guide rail 57 is installed before the floor surface is finished.

[0037] The support frame 59 is attached to the guide rail 57, whose lower end reaches the floor surface 23, with the same length, and is fixed to the fixing frame 51. The support frame 59 is made of a fire-resistant material, such as steel. The support frame 59 has a front support frame piece 87 and a rear support frame piece 89 that are bent at right angles on the opening side of the support frame body 85, which is parallel to the front surface 27 of the building structure 25, and on the opposite side, forming a roughly U-shape in plan view perpendicular to the longitudinal direction. At the bent end of the rear support frame piece 89, a support frame engaging piece 91 is formed, which is bent parallel to the support frame body 85 and engages with the fixing frame engaging piece 75.

[0038] The support frame 59 is fixed to one side of a guide rail 57 parallel to the front surface 27 of the building structure 25 by fasteners such as rivets 93. The support frame 59, while attached to the guide rail 57, is fixed to a fixing frame 51 that has been previously fixed to the building structure 25. To fix the support frame 59 to the fixing frame 51, first, the support frame engaging piece 91 is inserted into the inside of the fixing frame engaging piece 75. Next, the guide rail 57, which is integrated with the support frame 59, is rotated around the support frame engaging piece 91 that is engaged with the fixing frame engaging piece 75, so that the front support frame piece 87 is placed on the surface of the front fixing frame piece 71. A self-tapping screw 79 is passed through the surface of the front support frame piece 87 that is placed on the front fixing frame piece 71 to fasten the front support frame piece 87 and the front fixing frame piece 71.

[0039] The support frame 59 can be fixed by inserting the support frame engaging piece 91 into the inside of the fixing frame engaging piece 75 from the opening 15 side, and the fixing work can be completed only from the opening 15 side, thus improving workability.

[0040] For opening and closing mechanisms Guide rail 11 Therefore, the upper surface 48 of the foundation 47 is larger than the lower surface of the structural frame 25. The upper surface 48 of the foundation 47 extends horizontally into the interior from at least the front surface 27 of the structural frame 25 by an overhang E. The fixing frame 51 fixes the guide rail 57 to the structural frame 25 with a clearance K that is larger than the overhang E of the foundation 47 from the front surface 27 of the structural frame 25. In other words, the length of the rear piece 73 of the fixing frame 51 in the direction perpendicular to the front surface 27 is formed by the clearance K.

[0041] Figure 4 is a cross-sectional view of BB in Figure 1. The foundation opening side fixing member 61 is fixed to the inner surface 67 of the opening in the foundation 47 with concrete screws 95. The foundation opening side fixing member 61 is made of a long material with a length approximately the same as the height of the foundation 47, and its cross-sectional shape perpendicular to the longitudinal direction is L-shaped. One end of the L-shaped foundation opening side fixing member 61 becomes the foundation fixing piece 97, and the other end becomes the guide rail opposing piece 99.

[0042] The foundation connecting member 63 fixes the support frame 59 to the foundation opening side fixing member 61. The foundation connecting member 63 is fixed to the front piece 87 of the support frame 59 by self-tapping screws 79. The foundation connecting member 63 is made of a long material with a length approximately the same as the height of the foundation 47, and its cross-sectional shape perpendicular to the longitudinal direction is L-shaped. One side of the L-shaped foundation connecting member 63 becomes the connecting fixing piece 101, and the other side becomes the support frame fixing piece 103.

[0043] The foundation connecting member 63 is fixed to the support frame fixing piece 103 on the back side of the support frame front piece 87 opposite to the opening 15 by a self-tapping screw 79 that penetrates from the support frame front piece 87. In other words, the guide rail 57 can be fixed integrally with the support frame 59 and the foundation connecting member 63 in advance. In this case, the foundation opening side fixing member 61, positioned in a predetermined position, is fixed to the inner surface 67 of the opening of the foundation 47 with concrete screws 95. For opening and closing body Guide rail 11When the support frame 59 of the guide rail 57 is fixed to the fixing frame 51 above the step 49, the connecting fixing piece 101 of the foundation connecting member 63 comes into contact with the guide rail opposing piece 99 of the foundation opening side fixing member 61 parallel to it. As a result, the guide rail 57 is firmly fixed to the inner surface 67 of the opening in the foundation 47 by the self-tapping screws 79 that penetrate from the guide rail opposing piece 99 of the foundation opening side fixing member 61 and fasten to the connecting fixing piece 101, leaving the lower part of the fixing frame 51 absent.

[0044] The fixing of the foundation opening side fixing member 61 and the foundation connecting member 63 can be fastened from the outside side with self-tapping screws 79 to the guide rail opposing piece 99 and the connecting fixing piece 101 that overlap at the opening 15, and the fixing work can be completed only from the opening 15 side, thus improving workability.

[0045] For opening and closing mechanisms Guide rail 11 A cover plate 105 is fixed to the front surface 50 of the foundation 47 with concrete screws 95. The cover plate 105 is made of a long material that is approximately the same length as the height of the foundation 47, and has an L-shaped cross-section perpendicular to the longitudinal direction. One end of the L-shaped cover plate 105 becomes the foundation fixing piece 107, and the other end becomes the closing part 109. By fixing the foundation fixing piece 107 to the front surface 50 of the foundation 47, the cover plate 105 can close the slit-shaped gap S that has formed between the foundation 47 and the guide rail 57 with the closing part 109.

[0046] For opening and closing mechanisms Guide rail 11 The structure includes a housing frame 65, which is made of fire-resistant material and is detachably fixed to the other side of the guide rail 57 opposite to the support frame 59, covering the other side, and is connected to an opening / closing mechanism 39 that drives the opening and closing of the shutter curtain 19 via a signal transmission member inserted into the inner space 111, and a signal generating device facing the opening 15 at a predetermined height from the floor surface 23. The housing frame 65 has a recessed section 113 (see Figure 3) in a part facing the opening 15, where the signal generating device is mounted.

[0047] As shown in Figure 2, for opening and closing mechanism Guide rail 11Next, a housing frame 65 is fixed to the other side of the guide rail 57, which has a support frame 59 fixed to one side. The housing frame 65 is made of a fire-resistant material such as steel and covers the other side of the guide rail 57. A manual switching device 43 is attached to the housing frame 65, which is connected to an opening / closing mechanism 39 via a wire inserted into an internal space 111 and faces the opening 15 at a predetermined height from the floor surface 23. In addition to the manual switching device 43, an obstacle detection sensor 45 (see Figure 3) is also attached to the housing frame 65 at a predetermined height from the floor surface 23 and connected to a control unit 41 by a signal wire (not shown).

[0048] As shown in Figure 3, the housing frame 65 consists of a housing section 115 and a cover 117. The housing section 115 is fixed to the other side of the guide rail 57 by rivets 93, which are fixing means. The housing section 115 opens an inner space 111 along the guide rail 57 through a groove opening 119 on the opposite side of the guide rail 57. The cover 117 covers this groove opening 119 and is detachably fixed to the housing section 115.

[0049] The housing section 115 has a recessed section 113 formed in a part of the front piece 121 of the housing section facing the opening 15, where a signal generating device (manual switching device 43) is mounted. The recessed section 113 has a notch (not shown) for inserting and mounting a part of the manual switching device 43. Note that this notch is formed in the housing section 115 of the housing frame 65, and not in the guide rail 57. For opening and closing body Guide rail 11 Therefore, by making the mounting portion of the manual switching device 43 a stepped portion 113, the manual switching device 43 can be attached only to the housing portion 115 without overlapping the housing portion 115 and the cover 117, eliminating the need for processing such as cutting out notches in the cover 117.

[0050] The cover 117 is provided with a claw portion 123 on the inner cover piece 125 that engages with the groove opening 119 from the inside. The claw portion 123 is formed by bending at an acute angle. The bending angle of the claw portion 123 is, for example, 20 to 80°, preferably 60°. The claw portion 123 having this angle makes the cover 117 easy to install and less likely to fall off. In addition, the acute angle of the claw portion 123 also makes it less likely for the cover 117 to develop looseness. The cover 117 is provided with an L-shaped bent portion 127 on the front cover piece 129 that is fastened to the front receiving piece 121 with fixing screws, and whose bent tip engages with the stepped portion 113. The L-shaped bent portion 127 of the cover 117 allows the edge to be hooked into the stepped portion 113 and directed toward the bottom of the groove, preventing it from being exposed. This makes it possible to neatly finish the edge of the sheet metal material.

[0051] Next, the assembly procedure for the guide rail 11 for the opening and closing mechanism will be explained.

[0052] Figure 5(a) is a plan view showing the fixing status between the structural frame 25 and the fixing frame 51 at the AA section position in Figure 1, and (b) is a plan view showing the fixing status between the foundation 47 and the foundation opening side fixing member 61 and the foundation connecting member 63 at the BB section position in Figure 1. To assemble the guide rail 11 for opening and closing, first, as shown in Figure 5(a), the structural frame opening inner surface fitting 53 is fixed to the inner surface 26 of the opening in the structural frame 25 using coarse thread screws 77. The structural frame front fitting 55 is fixed to the rear piece 73 of the fixing frame 51 using self-tapping screws 79. The structural frame front fitting 55, which is integrally fixed to the fixing frame 51, is fixed to the front surface 27 of the structural frame 25 using coarse thread screws 77. The self-tapping screws 79, which have been passed through the fixing frame body 69 of the fixing frame 51, are fixed to the structural frame opening inner surface fitting 53. This completes the fixing of the fixing frame 51 to the structural frame 25.

[0053] As shown in Figure 5(b), the foundation opening side fixing member 61 is fixed to the inner surface 67 of the opening in the foundation 47 with concrete screws 95. At this time, the foundation connecting member 63 may be fixed to the foundation opening side fixing member 61 in advance with self-tapping screws 79. Alternatively, the foundation connecting member 63 may be fixed to the front piece 87 of the support frame 59 with self-tapping screws 79 before fixing it to the foundation opening side fixing member 61.

[0054] Figure 6 is a plan cross-sectional view showing the fixing of the fixed frame 51 and the support frame 59. The guide rail 57, fixed to the support frame 59, engages the support frame engaging piece 91 of the support frame 59 with the fixing frame engaging piece 75 of the fixing frame 51. Next, the guide rail 57 is rotated clockwise in Figure 6 around the support frame engaging piece 91, and the front piece 87 of the support frame is placed on the surface of the front piece 71 of the fixing frame. A self-tapping screw 79, which has been passed through the front piece 87 of the support frame, is fastened to the front piece 71 of the fixing frame. This completes the fixing of the guide rail 57 to the structure 25. At this time, the housing frame 65 is attached to the guide rail 57 in advance.

[0055] Figure 7 is a plan cross-sectional view showing the fixing of the support frame 59 and the foundation 47. The guide rail 57, with its support frame 59 fixed to the fixing frame 51, has its front support frame piece 87 overlapping the support frame fixing piece 103 of the foundation connecting member 63, which is fixed to the foundation opening side fixing member 61 fixed to the foundation 47. The support frame 59 fastens the support frame fixing piece 103 with a self-tapping screw 79 that penetrates from the front support frame piece 87. As a result, the lower part of the guide rail 57 below the step 49 is fixed to the foundation 47 via the support frame 59, the foundation connecting member 63, and the foundation opening side fixing member 61. If the lower end of the guide rail 57 is to be embedded in the floor, the floor surface 23 is finished after this.

[0056] Furthermore, when the foundation connecting member 63 is pre-fixed to the front piece 87 of the support frame, the fixing of the foundation opening side fixing member 61 to the support frame 59 is completed by fastening the connecting fixing piece 101 of the foundation connecting member 63 to the guide rail opposing piece 99 of the foundation opening side fixing member 61 with a self-tapping screw 79.

[0057] Figure 8 is a plan cross-sectional view showing the fixing status of the cover plate 105 that closes the gap S between the foundation 47 and the guide rail 57. Guide rail 57 is fixed to the structure 25 and foundation 47 for opening and closing mechanism. Guide rail 11 Finally, the cover plate 105 is fixed to the foundation 47. The cover plate 105 is fixed to the front surface 50 of the foundation 47 with concrete screws 95 by fixing the foundation fixing piece 107 to the front surface 50 of the foundation 47, thereby closing the slit-shaped gap S between the foundation 47 and the guide rail 57 with the cover portion 109. This allows the opening and closing mechanism to be closed. Guide rail 11 Complete the assembly.

[0058] Next, I will explain the function of the above-described configuration.

[0059] For opening and closing mechanisms according to this embodiment Guide rail 11 The structural frame 25 then rests on the upper surface 48 of the foundation 47, which rises from the floor surface 23. The structural frame 25 is placed on the foundation 47 with a step 49, as the lower surface of the smaller side of the foundation 47 rests on the upper surface 48.

[0060] Figure 9 is an exploded plan view of the guide rail 11 for the opening and closing mechanism. Each guide rail 57 that guides the edges on both sides in the width direction of the shutter curtain 19 is positioned at both ends in the width direction of the opening 15, with its lower end reaching the floor surface 23 and extending vertically. The opening / closing guide rail 11 for fixing this guide rail 57 to the building has a fixing frame 51, a support frame 59, a foundation opening side fixing member 61, and a foundation connecting member 63 as its main fixing members.

[0061] The fixed frame 51 has a portion of its lower end resting on the step 49 and is fixed to the inner surface 26 of the opening and to one of the indoor or outdoor surfaces (front 27) of the building structure 25. In other words, the fixed frame 51 can be erected with the position of the step 49 as a reference and is fixed to the building structure 25 above the step 49.

[0062] The support frame 59 is attached to the guide rail 57, whose lower end reaches the floor surface 23, with the same length. The support frame 59, like the guide rail 57, stands upright along the foundation 47 and the building structure 25. The support frame 59 above the step 49 is fixed to a fixing frame 51 which is fixed to the building structure 25. As a result, the guide rail 57 above the step 49 is firmly fixed to the building structure 25 via the fixing frame 51 and the support frame 59.

[0063] On the other hand, the support frame 59 has a foundation connecting member 63 fixed to the portion of the foundation 47 below the step 49 where the fixing frame 51 is absent. A foundation opening side fixing member 61 is fixed to the portion of the foundation 47 corresponding to this foundation connecting member 63. The lower part of the support frame 59 is firmly fixed to the foundation 47 by fastening these foundation connecting members 63 and the foundation opening side fixing member 61 together. In other words, the guide rail 57 is fixed to the structure 25 above the step 49 by the support frame 59 and the fixing frame 51, and fixed to the foundation 47 below the step 49 by the support frame 59, the foundation connecting member 63 and the foundation opening side fixing member 61. Guide rail 11 As a result, the guide rail 57 can be fixed to the structure 25 by the fixing frame 51 and the support frame 59 without interfering with the step 49 of the foundation 47.

[0064] Thus, for opening and closing mechanisms Guide rail 11 Therefore, the guide rail 57 and the support frame 59 fixed to the guide rail 57 are attached to the building with nearly identical cross-sections at any point along their longitudinal direction, without needing to be cut out to avoid interference with the foundation 47. This eliminates the need for complicated work such as cutting out a portion of the guide rail 57 with fire.

[0065] Furthermore, the guide rail 57 does not suffer a reduction in strength due to the notch provided to avoid the foundation 47. In addition, the complicated construction management required by the building side, which involves coordinating with the site in advance to ensure that there is no step 49 between the foundation 47 and the column only where the guide rail 57 is to be installed, is not necessary.

[0066] In addition, since no fire processing is performed, fire prevention measures are unnecessary. Furthermore, poor finishes and rust are less likely to occur, resulting in a better appearance and increased durability. Moreover, when replacing guide rails 57 at an existing site, there is no need to cut away the step 49, so new guide rails 57 can be installed without reducing the strength of the foundation 47.

[0067] For this opening and closing mechanism Guide rail 11 Then, the guide rail 57 is fixed to the structure 25 by the fixing frame 51 and the support frame 59 with a clearance K that is larger than the overhang E of the foundation 47. As a result, the guide rail 57 can be firmly fixed vertically to the structure 25 and the foundation 47 without interfering with the foundation 47.

[0068] The lower end of the fixed frame 51 rests on the step 49, so it is absent below the step 49. The support frame 59 has a foundation connecting member 63 fixed to the portion of the foundation 47 where the fixed frame 51 is absent below the step 49. The foundation connecting member 63 is fixed to the foundation opening side fixing member 61 which is fixed to the foundation 47. Therefore, for opening and closing Guide rail 11 As a result, the lower part of the support frame 59, where the fixing frame 51 is absent, is firmly fixed to the foundation 47 by the foundation connecting member 63 and the foundation opening side fixing member 61. Consequently, the guide rail 57 can be installed with a clearance K larger than the overhang E of the foundation 47, spaced apart from one side of the structure 25, and the guide rail 57 can be erected vertically from the floor surface 23 while avoiding the foundation 47 without cutting out the guide rail 57.

[0069] Also, for this opening and closing mechanism Guide rail 11Next, a support frame 59 of the same length is attached to and fixed to the guide rail 57. This support frame 59 is fixed to a fixed frame 51 attached to the structural frame 25. The fixed frame 51 fixes the support frame 59 and the guide rail 57 to the structural frame 25 with a clearance K that is larger than the overhang E of the foundation 47. In other words, a gap S is created between the support frame 59 attached to the guide rail 57 and the foundation 47. This gap S does not occur above the step 49 because the fixed frame 51 and the support frame 59 are fixed together. On the other hand, the fixed frame 51 is absent from the foundation 47 below the step 49, so only the support frame 59 is positioned along the foundation 47. Since the guide rail 57 is spaced away from the structural frame 25 with a clearance K that is larger than the overhang E of the foundation 47, a gap S (S=KE), which is the difference between the clearance K and the overhang E, is created between the guide rail 57 and the foundation 47. For opening and closing mechanisms Guide rail 11 Then, the slit-shaped gap S along the foundation 47 will be blocked by the concealing plate 105 fixed to the foundation 47.

[0070] Furthermore, the privacy panel 105 only needs to be fixed to the foundation 47 and does not need to be fixed to the guide rail 57. However, since it is a privacy screen, it needs to be the same length as the height of the foundation 47. The upright portion of the foundation 47 above the floor surface 23 is about 300 to 500 mm, so the privacy panel 105 will be of a similar length. As a result, the gap S that occurs when the fixing frame 51 is absent on one side of the foundation 47 can be closed by the privacy panel 105 which is installed across the guide rail 57 and the foundation 47, and the opening and closing mechanism Guide rail 11 This can suppress quality degradation in that regard.

[0071] Also, for this opening and closing mechanism Guide rail 11 Therefore, since the other side of the guide rail 57 is covered with a housing frame 65 made of fire-resistant material, such as steel, the effects of flames on the guide rail 57 during a fire can be suppressed compared to a configuration in which a non-fire-resistant material, such as aluminum, is used for the housing frame 65. In other words, the strength (fire resistance) of the opening and closing body guide rail 11 when exposed to flames can be increased.

[0072] Furthermore, the housing frame 65, which covers and fixes the other side of the guide rail 57, has an internal space 111 that can be used as a space for inserting a signal transmission member. Therefore, a signal generating device (manual switching device 43) attached to the surface of the housing frame 65 facing the opening 15 (front piece 121 of the housing section) can be easily connected to the switch 39 using the space 111 of the housing frame 65.

[0073] The housing frame 65 has a recessed section 113 formed in a part of the housing front piece 121 facing the opening 15, where the signal generating equipment is mounted. The recessed section 113 is formed by bending the housing front piece 121 toward the space 111 in a stepped manner, making it recessed compared to the housing front piece 121. In other words, the recessed section 113 forms a vertical groove recessed along the guide rail 57 between the guide rail 57 and the housing front piece 121. The housing 115 is mounted by inserting a part of the signal generating equipment into a notch formed in the bottom surface of the groove of this recessed section 113.

[0074] For opening and closing mechanisms Guide rail 11 Since a stepped section 113 is formed in the housing section 115 and a notch is formed only in the stepped section 113, there is no need to align it with the notch formed in the cover 117. This simplifies alignment and makes installation easy. Furthermore, since there is no misalignment, the signal generating equipment can be accurately mounted, eliminating the risk of compromising the aesthetics. In addition, since a notch is provided on the bottom surface of the groove of the stepped section 113, the finished structure of the mounting part is not conspicuous, and the edges of the steel plate used as a component of the cover 117 are not exposed, resulting in a good aesthetic appearance. As a result, the other side of the guide rail 57 is covered by the housing frame 65 made of fire-resistant material, so the fire resistance of the guide rail 57 can be enhanced by covering it with fire-resistant material, and the signal transmission member can be inserted using the inner space 111, making it easy to mount the signal generating equipment to the housing frame 65. Furthermore, the stepped section 113 prevents the edges of the housing frame 65 from being exposed, thereby achieving a good aesthetic design.

[0075] Therefore, the opening and closing mechanism according to this embodiment Guide rail 11 According to this, even if there is a step 49 between the foundation 47 and the structural frame 25, the guide rail 57 that rises vertically from the floor surface 23 can be attached to the structural frame 25 without cutting or using fire, thereby suppressing a decline in quality.
