Description

[Technical Field]

[0001] The present invention relates to a scaffold for stained glass. [Background technology]

[0002] Many stained glass windows are found in ancient castles and palaces in England and elsewhere, and many have been brought to Japan as a result of the demolition of buildings overseas. Because many of these stained glass windows are of historical value and highly decorative, they are often used in modern Japanese buildings, such as altars in churches. Stained glass windows are decorated by projecting decorations onto the surface using direct lighting or daylight from behind, or by using light reflected from a mirror. Large stained glass windows exceeding 3 meters in height are often installed in halls, churches, etc. When cleaning or repairing such large stained glass windows or replacing lighting, scaffolding for working at height, such as that disclosed in Patent Document 1, is required. Behind the stained glass, a space is provided for illuminating the stained glass with lighting or daylight, and scaffolding is set up in this space when cleaning or repairing the back of the stained glass or replacing lighting.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-59544 Summary of the Invention [Problem to be solved by the invention]

[0004] The space behind the stained glass is extremely narrow. Therefore, the installation and removal of scaffolding in the space behind the stained glass requires careful attention to ensure that the scaffolding components do not come into contact with the stained glass, which takes time and effort. On the other hand, if scaffolding is permanently installed in the space behind the stained glass, shadows of the scaffolding will be cast on the stained glass and in the room when lighting or daylight is shone on the stained glass, which creates the problem of impairing the appearance of the altar and other indoor spaces.

[0005] Therefore, the object of the present invention is to provide a scaffolding for stained glass that can be permanently installed in the space behind the stained glass without casting a shadow on the stained glass or inside the room when lighting or daylight is shone on the stained glass. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objectives, the stained glass scaffolding of the present invention is positioned behind the vertical frames extending in the vertical direction on both sides of the stained glass and is supported by a frame base that supports the vertical frames, and has a guide rail that extends in the front-to-back direction at a predetermined height behind the frame base, and a sliding scaffolding board that can move in the front-to-back direction along the guide rail.

[0007] In the present invention, the sliding scaffolding plate moves back and forth behind the stained glass. Therefore, during normal times when cleaning or repairing the back of the stained glass or replacing lighting is not required, the sliding scaffolding plate is positioned at the rear. When cleaning or repairing the back of the stained glass or replacing lighting is required, the sliding scaffolding plate can be moved forward and positioned near the back of the stained glass. In other words, a permanent scaffold can be used for cleaning or repairing the back of the stained glass or replacing lighting. Conventionally, it was necessary to set up and remove scaffolding every time the back of the stained glass was cleaned or repaired or lighting was replaced. However, by permanently installing the stained glass scaffolding of the present invention, this setup and removal is no longer necessary, making the work easier. By moving the sliding scaffolding board backward, a gap is created between the back of the stained glass and the sliding scaffolding board. Therefore, by moving the sliding scaffolding board backward, the shadow of the sliding scaffolding board is prevented from being cast on the stained glass or the room when lighting or daylight is shone on the stained glass. In other words, by moving the sliding scaffolding board backward during normal times when the back of the stained glass is not being cleaned or repaired, or lighting is not being replaced, the shadow of the sliding scaffolding board is not cast on the stained glass or the room. Therefore, even if scaffolding is permanently installed in the space behind the stained glass, the design of the stained glass is not affected. Because the guide rails are supported by a base frame provided behind the frame on the side of the stained glass, the stained glass scaffolding can be constructed simply.

[0008] The stained glass scaffolding of the present invention may have a beam portion joined to the frame base and extending rearward from the frame base, and the beam portion may support the guide rail.

[0009] With this configuration, the guide rails can be installed in a stable state.

[0010] The stained glass scaffolding of the present invention may have a scaffolding supported by the frame base located behind the vertical frames provided on both sides of each of the multiple stained glass pieces arranged horizontally, and positioned at a predetermined height behind the guide rails.

[0011] With this configuration, scaffolding is placed continuously behind the sliding scaffolding boards that are placed behind each of the multiple stained glass pieces, so that when multiple stained glass pieces are arranged, it is possible to move between the sliding scaffolding boards via the scaffolding.

[0012] In the stained glass scaffolding of the present invention, the guide rail and the sliding scaffolding board may be arranged behind a horizontal frame extending laterally and provided in the middle of the stained glass in the vertical direction.

[0013] With this configuration, even if the shadows of the guide rails and sliding scaffolding boards are reflected on the stained glass when illuminated or exposed to daylight, the shadows of the guide rails and sliding scaffolding boards will be reflected on the horizontal frame of the stained glass, preventing the shadows of the guide rails and sliding scaffolding boards from being reflected on the main body of the stained glass or inside the room. [Effects of the Invention]

[0014] According to the present invention, when the stained glass is illuminated by light or daylight, no shadows are cast on the stained glass or inside the room, and the device can be permanently installed in the space behind the stained glass. [Brief explanation of the drawings]

[0016] (First embodiment) Hereinafter, a scaffold for stained glass according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 9. FIG. As shown in FIG. 1, the stained-glass scaffolding 1 according to this embodiment is installed in a space 11 behind the stained-glass 2 (hereinafter referred to as the rear space 11). A wall 12 is provided at the rear of the rear space 11. The stained-glass 2 is a large, vertically elongated plate, for example, about 3 m in height. In this embodiment, multiple stained-glass pieces 2 are arranged on an arc in a plan view from above and below. The stained-glass scaffolding 1 is used when cleaning, repairing, or replacing lighting (hereinafter referred to as maintenance) the stained-glass 2 at high locations. The stained-glass 2 is plate-shaped. The horizontal direction along the surface of the stained-glass 2 is referred to as the lateral direction. The direction perpendicular to the surface of the stained-glass 2 is referred to as the front-to-rear direction. The stained-glass 2 is designed to be viewed from the front. The space in front of the stained-glass 2 is referred to as the room 13. The stained-glass scaffolding 1 according to this embodiment is equipped with a sliding scaffolding board 6 that moves in the front-to-rear direction. When maintenance is not being performed, the sliding scaffolding board 6 is normally positioned at the rear, away from the stained glass 2, as shown in Figure 1, and when maintenance is being performed, it is positioned at the front, close to the stained glass 2, as shown in Figure 2. In Figure 3 and subsequent figures, the horizontal direction is indicated by arrow X, the front-to-rear direction is indicated by arrow Y, and the height direction is indicated by arrow Z.

[0017] As shown in Figures 1 to 4, the stained glass 2 has a stained-glass main body 21, vertical frames 22, and horizontal frames 23. The stained-glass main body 21 is formed in a plate shape and is decorated with pictures, patterns, and other decorations. In this embodiment, multiple stained-glass main bodies 21 are arranged in the vertical direction. A pair of vertical frames 22 is provided on both sides of each of the multiple stained-glass main bodies 21. The vertical frames 22 are long members that extend in the vertical direction. Each pair of vertical frames 22 is attached to the side edges of each of the multiple stained-glass main bodies 21. The horizontal frames 23 are provided at the top and bottom of each of the multiple stained-glass main bodies 21, and between adjacent stained-glass main bodies 21 in the vertical direction. The horizontal frames 23 are long members that extend in the horizontal direction. The multiple horizontal frames 23 are attached to the upper and lower edges of each of the multiple stained-glass main bodies 21.

[0018] The stained glass 2 is supported by a frame base 3 provided at the rear. The frame base 3 has a frame base column 31 and a frame base beam 32. The frame base column 31 is a long member extending in the vertical direction. The frame base column 31 is a square pipe or the like. The frame base column 31 is fixed to a structural frame such as the floor of the building in which the stained glass 2 is installed. The frame base column 31 may also be fixed to a beam or ceiling of the building in which the stained glass 2 is installed. The frame base column 31 is provided at a distance behind each of the vertical frames 22 of the stained glass 2. The frame base column 31 is provided behind each of a pair of vertical frames 22 for each stained glass 2. In other words, two frame base columns 31 are provided for each stained glass 2. The frame base beam 32 is a long member extending in the front-to-rear direction. The frame base beam 32 connects the uppermost horizontal frame 23 of the stained glass 2 to the frame base column 31.

[0019] As shown in Figures 4 to 7, the stained glass scaffolding 1 has a beam 4, a guide rail 5, a sliding scaffolding board 6, and a scaffolding 7. The beam 4 is a long member that extends rearward from each of the two frame base columns 31, 31 on either side of the stained glass 2. The beam 4 is a square pipe or the like. The guide rail 5 is fixed onto each of the two beams 4, 4. The guide rail 5 is a long member that extends in the front-to-rear direction. The guide rail 5 is approximately the same length as the beam 4. The guide rail 5 is a piece of angle iron or the like with an L-shaped cross section.

[0020] The sliding scaffolding board 6 is placed on two guide rails 5, 5. The sliding scaffolding board 6 is arranged to span over the two guide rails 5, 5. The length dimension in the front-to-rear direction of the guide rails 5 is longer than the length dimension in the front-to-rear direction of the sliding scaffolding board 6. The sliding scaffolding board 6 is movable in the front-to-rear direction along the guide rails 5, 5. The sliding scaffolding board 6 has a plate-shaped scaffolding board portion 61 and casters 62 attached to the scaffolding board portion 61 and running on the guide rails 5. A worker can stand on the scaffolding board portion 61. A stopper 51 is provided at the rear end of the guide rail 5 to prevent the casters 62 from moving backward.

[0021] The beams 4, guide rails 5, and sliding scaffolding planks 6 are provided at approximately the same height as the horizontal frames 23 of the stained glass 2. As shown in Figure 4, in this embodiment, multiple sets of beams 4, guide rails 5, and sliding scaffolding planks 6 are provided at intervals in the vertical direction. Each set of beams 4, guide rails 5, and sliding scaffolding planks 6 is provided at approximately the same height as the horizontal frames 23 of the stained glass 2.

[0022] As shown in Figures 4 to 7, the scaffolding 7 has a scaffolding post 71, a scaffolding beam 72, a scaffolding girder 73, and a scaffolding walkway board 74. The scaffolding post 71 is a long member extending in the vertical direction. The scaffolding post 71 is made of a single pipe or the like. Two scaffolding posts 71 are arranged behind each of the multiple frame base posts 31, spaced apart in the front-to-back direction. The scaffolding beam 72 is a long member extending in the horizontal direction. The scaffolding beam 72 is made of a single pipe or the like. Both horizontal ends of the scaffolding beam 72 are fixed to the scaffolding post 71. Two scaffolding beams 72 are arranged spaced apart in the front-to-back direction. The scaffolding girder 73 is a long member extending in the front-to-back direction. The scaffolding girder 73 is hung on the two scaffolding beams 72. The scaffolding passage plank 74 is a plate-shaped member and is installed with its surface oriented horizontally. The scaffolding passage plank 74 is fixed onto the scaffolding beam 73. A worker can stand on the scaffolding passage plank 74. The scaffolding passage plank 74 is positioned at a height close to the scaffolding board portion 61 of the sliding scaffolding board 6. In this embodiment, as shown in FIGS. 1 and 2, a scaffolding passage plank 741 is also provided between the scaffolding passage planks 74 positioned behind adjacent stained glass windows 2 so that the entire rear space 11 of the multiple stained glass windows 2 can be moved. The scaffolding passage plank 741 is supported by the scaffolding beam 73 positioned behind the adjacent stained glass windows 2. As shown in FIGS. 4 and 6, the front end portion 74a of the scaffolding passage plank 74 is positioned near the rear end portion 4a of the beam portion 4.

[0023] As shown in Figures 1, 8, and 9, the sliding scaffolding board 6 is normally positioned above the rear portion of the guide rail 5. As shown in Figures 2, 6, and 7, the sliding scaffolding board 6 is positioned above the front portion of the guide rail 5 during maintenance. When positioned at the rear, the sliding scaffolding board 6 is positioned at a distance behind the stained glass 2. The distance between the sliding scaffolding board 6 and the stained glass 2 is set so that shadows are not cast on the stained glass 2 or inside the room when lighting or daylight is applied to the space 11 behind the stained glass 2. When positioned at the front, the sliding scaffolding board 6 is positioned immediately behind the stained glass 2. When positioned at the front, workers can stand on the sliding scaffolding board 6 to perform maintenance on the stained glass 2. The scaffolding walkway board 74 and the sliding scaffolding board 6 are designed to allow workers to move back and forth. The stained glass scaffolding 1 may be provided with a stopper or the like for maintaining the sliding scaffolding board 6 in a state where it is positioned at the front side or at the rear side.

[0024] In the stained-glass scaffolding 1 according to this embodiment, the sliding scaffolding board 6 moves back and forth behind the stained-glass piece 2. By moving the sliding scaffolding board 6 forward, it can be positioned close to the back of the stained-glass piece 2, allowing maintenance of the back of the stained-glass piece 2. By moving the sliding scaffolding board 6 backward, a gap is created between the back of the stained-glass piece 2 and the sliding scaffolding board 6. Therefore, by moving the sliding scaffolding board 6 backward, it is possible to prevent the shadow of the sliding scaffolding board 6 from being cast on the stained-glass piece 2 or inside the room when lighting or daylight is shone on the stained-glass piece 2. In other words, by moving the sliding scaffolding board 6 backward under normal circumstances, the shadow of the sliding scaffolding board 6 is not cast on the stained-glass piece 2 or inside the room, so even if scaffolding is permanently installed in the space behind the stained-glass piece 2, the design of the stained-glass piece 2 is not affected. Since the guide rails 5 are supported by the frame base 3 provided behind the vertical frame 22 provided on the side of the stained glass 2, the stained glass scaffolding 1 can be simply configured.

[0025] In the stained glass scaffolding 1 according to this embodiment, the guide rails 5 are supported by beams 4 joined to the frame base 3. With this configuration, the guide rails 5 can be installed in a stable state.

[0026] In the stained glass scaffolding 1 according to this embodiment, the scaffolding 7 is placed at a predetermined height behind the guide rails 5. With this configuration, the scaffolding 7 is placed continuously behind the sliding scaffolding boards 6 that are placed behind each of the multiple stained glass pieces 2, so that when multiple stained glass pieces 2 are arranged, it is possible to move between the sliding scaffolding boards 6 via the scaffolding 7.

[0027] In the stained-glass scaffolding 1 according to this embodiment, the beams 4, guide rails 5, and sliding scaffolding boards 6 are positioned at approximately the same height as the horizontal frames 23 of the stained-glass 2. With this configuration, even if shadows of the beams 4, guide rails 5, and sliding scaffolding boards 6 are cast on the stained-glass 2 when illuminated or exposed to daylight, the shadows are prevented from being cast on the horizontal frames 23 of the stained-glass 2 and onto the stained-glass body 21 or the interior of the room.

[0028] (Second embodiment) Next, a second embodiment will be described. The same or similar members and parts as those in the first embodiment will be denoted by the same reference numerals, and the description will be omitted. Only the configurations different from those in the second embodiment will be described. As shown in Figures 10 and 11, the stained glass scaffolding 1B according to the second embodiment does not have the scaffolding passage boards 74 as in the first embodiment. In the second embodiment, the beams 4B and guide rails 5B extend across the entire fore-and-aft direction of the rear space 11. The beams 4B may be supported not only by the frame base 3 but also by the scaffolding columns 71, scaffolding beams 72, and scaffolding girders 73 as in the first embodiment.

[0029] As shown in Figures 12 and 13, the sliding scaffolding board 6B is normally positioned above the rear portion of the guide rail 5B. As shown in Figures 10 and 11, the sliding scaffolding board 6B is positioned above the front portion of the guide rail 5B when performing maintenance. As shown in Figures 12 and 13, when the sliding scaffolding board 6B is positioned at the rear, it is positioned at a distance behind the stained glass 2. The distance between the sliding scaffolding board 6B and the stained glass 2 is set so that when lighting or daylight is applied to the space 11 behind the stained glass 2, no shadows are cast on the stained glass 2 or inside the room. As shown in Figures 10 and 11, when the sliding scaffolding board 6B is positioned at the front, it is positioned immediately behind the stained glass 2. When the sliding scaffolding board 6B is positioned at the front, a worker can stand on the sliding scaffolding board 6B to perform maintenance on the stained glass 2.

[0030] The stained-glass scaffolding 1B according to the second embodiment described above has the same effect as the stained-glass scaffolding 1 of the first embodiment. If the length of the rear space 11 of the stained glass 2 in the front-to-rear direction is the same, the sliding scaffolding board 6B can be positioned further rearward under normal conditions compared to when the stained-glass scaffolding 1 of the first embodiment is installed.

[0031] The above describes an embodiment of the stained glass scaffolding according to the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the spirit thereof. For example, in the first embodiment described above, the beam portion 4 is supported only by the frame base 3, but it may also be supported in addition to the frame base 3 by pillars erected on the floor of the building in which the stained glass 2 is installed, or by components hanging from the ceiling.

[0032] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the United Nations Summit in September 2015. The stained glass scaffolding 1, 1B according to this embodiment can contribute to the achievement of the 17 goals of the SDGs, for example, goal 12: Responsible Consumption and Production.
