[0022] In this invention, the suspension device is securely fixed to the support material. [Brief explanation of the drawing]

[0023] [Figure 1] Figure 1 is a side view of the lifting device. [Figure 2] Figure 2 is a vertical cross-sectional view of the plane along the line II-II shown in Figure 1. [Modes for carrying out the invention]

[0024] Embodiments will be described below with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The scope of the present invention is not limited to the examples in the drawings, as the drawings are provided for illustrative purposes only.

[0025] <1. Lifting equipment> Figure 1 is a side view of the lifting device. Figure 2 is a vertical cross-sectional view taken along line II-II shown in Figure 1, viewed in the direction of the arrow.

[0026] The ceiling on which the suspension device 20 is installed is a ceiling installed above a space in the building such as an inner balcony, outdoor living room, living room, earthen floor, entrance hall, entrance porch, storage room, washroom, stairwell, or corridor. The space below the ceiling is the building's indoor or outdoor space. This building is a wooden building, a reinforced concrete building, a steel-reinforced concrete building, or a steel-frame building. The building may have a wall structure, a frame structure, or both. A wall structure is one in which the walls support the load of the building itself, the load of the load of the load, and seismic forces. A frame structure is one in which the columns and beams support the load of the building itself, the load of the load, and seismic forces. The building may be constructed using a panel method, a frame method, a frame-panel method, or a frame wall method, or a combination of two or more of these. In one example, the building is a wooden building with a wall structure constructed using a wood panel adhesive method, which is a type of panel method, and the main components of the building, such as the walls, floors, ceilings, and roof, are wood panels. The wooden panel comprises a wooden frame formed by assembling four frame members into a rectangular frame, wooden facing materials attached to the front and back surfaces of the frame, and wooden auxiliary crossbars arranged vertically, horizontally, or vertically and horizontally inside the frame. The wooden panel may also have insulation material filled inside the rectangular frame.

[0027] The ceiling has support members 10, joists 3, insulation boards 4, ceiling boards 5, and hanging fixtures 20.

[0028] The support material 10 is, for example, a piece of wood such as a beam, frame member, or ceiling joist. The beam may be, for example, a main beam, secondary beam, diagonal beam, or roof beam. Here, "beam" includes girders. The frame member may constitute the frame material of a wooden panel as described above. The support material 10 may also be a structural material. A structural material is a material that bears the load of the building itself, the load of the loaded objects, and seismic forces.

[0029] The ceiling joists 3 are suspended from the support members 10 by hanging members and, if necessary, by joist hangers. The ceiling joists 3 are installed horizontally. The insulation boards 4 are laid on top of the ceiling joists 3. The ceiling boards 5 are attached to the bottom of the ceiling joists 3.

[0030] The ceiling board 5 has a hole 5a that penetrates it vertically. The hole 5a is located directly below the suspension fixture 20.

[0031] The suspension device 20 is a ceiling suspension device installed on the ceiling. The suspension device 20 is used to suspend objects such as hammocks, clotheslines, play equipment, projection screens, banners, ropes, or wires. The suspension device 20 comprises a main body 30, a dowel 40, a first support pin 50, a second support pin 60, two reinforcing plates 70 and 80, and a connector 90. The support pins 50 and 60 are also called drift pins.

[0032] The main body 30 is provided in the shape of a rectangular prism. The main body 30 is made of wood. However, the main body 30 may be made of a metal material such as stainless steel or aluminum alloy. The upper surface 31 of the main body 30 is in surface contact with the lower surface 11 of the support member 10. The main body 30 hangs down from the lower surface 11 of the support member 10. The width of one side 33 of the main body 30 to the opposite side 34 is equal to the width of the support member 10 from one side 13 to the opposite side 14. Both sides 33 and 34 of the main body 30 are flush with both sides 13 and 14 of the support member 10, respectively.

[0033] Dowel holes 32 and 12 are formed on the upper surface 31 of the main body 30 and the lower surface 11 of the support member 10, respectively. Dowels 40 are fitted into dowel holes 32 and 12. Dowels 40 are made of a metal material such as stainless steel or aluminum alloy.

[0034] The through hole 41 penetrates the top of the dowel 40 in a direction perpendicular to the central axis direction of the dowel 40. The central axis direction of the dowel 40 is the direction in which the dowel 40 is inserted into the dowel holes 12 and 32. On the other hand, the through hole 15 penetrates the side surface 13 of the support material 10 through the dowel hole 12 to the side surface 14 in the width direction. The through hole 15 and the through hole 41 are connected in a continuous line, and a metal first support pin 50, such as one made of stainless steel or aluminum alloy, is fitted into these through holes 15 and 41. The insertion of the first support pin 50 into the through holes 15 and 41 prevents the dowel 40 from coming out of the dowel hole 12. The first support pin 50 may have irregularities on its outer surface, and these irregularities may contribute to preventing the first support pin 50 from coming out of the through holes 15 and 41.

[0035] The through-hole 42 penetrates the top of the dowel 40 in a direction perpendicular to the central axis of the dowel 40. On the other hand, the through-hole 35 penetrates the widthwise from the side surface 33 of the main body 30 through the dowel hole 32 to the side surface 34. The through-holes 35 and 42 are connected in a continuous line, and a second support pin 60 made of metal, such as stainless steel or aluminum alloy, is fitted into these through-holes 35 and 42. The insertion of the second support pin 60 into the through-holes 35 and 42 prevents the dowel 40 from coming out of the dowel hole 32. The second support pin 60 may have irregularities on its outer surface, and these irregularities may contribute to preventing the second support pin 60 from coming out of the through-holes 35 and 42. The main body 30 is fixed to the suspension device 20 by dowels 40 and support pins 50 and 60.

[0036] Both ends of the first support pin 50 protrude slightly from both ends of the through hole 15. Both ends of the second support pin 60 protrude slightly from both ends of the through hole 35.

[0037] A metal reinforcing plate 70, such as one made of stainless steel or aluminum alloy, makes surface contact with the side surface 13 of the support material 10 and the side surface 33 of the main body 30. The reinforcing plate 70 is fastened to the side surface 13 of the support material 10 and the side surface 33 of the main body 30 by multiple screws 79. Two holes 71 and 72 are formed in the reinforcing plate 70, and the ends of support pins 50 and 60 are inserted into the holes 71 and 72, respectively.

[0038] Alternatively, holes 71 and 72 may not be formed in the reinforcing plate 70, and the ends of the support pins 50 and 60 may not protrude from both ends of the through-holes 15, but rather the ends of the support pins 50 and 60 may abut against the reinforcing plate 70. Such a reinforcing plate 70 helps prevent the support pins 50 and 60 from coming loose.

[0039] A metal reinforcing plate 80, such as one made of stainless steel or aluminum alloy, makes surface contact with the side surface 14 of the support material 10 and the side surface 34 of the main body 30. The reinforcing plate 80 is fastened to the side surface 14 of the support material 10 and the side surface 34 of the main body 30 by multiple screws 89. Two holes are formed in the reinforcing plate 80, and the ends of support pins 50 and 60 are inserted into the two holes, respectively.

[0040] Alternatively, the reinforcing plate 80 may not have holes, and the ends of the support pins 50 and 60 may not protrude from either end of the through-hole 35, but rather abut against the reinforcing plate 80. Such a reinforcing plate 80 helps prevent the support pins 50 and 60 from coming loose.

[0041] The first support pin 50 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. The second support pin 60 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. Both support pins 50 and 60 may be integrally formed with either the reinforcing plate 70 or the reinforcing plate 80. One of the support pins 50 or 60 may be integrally formed with the reinforcing plate 70, and the other with the reinforcing plate 80.

[0042] The reinforcing plates 70 and 80 reinforce the mutual fixing of the suspension device 20 and the main body 30 by the dowels 40 and support pins 50 and 60. The reinforcing plates 70 and 80 prevent the main body 30 from rattling.

[0043] While the reinforcing material is plate-shaped, as in the reinforcing plates 70 and 80, it may also be block-shaped and sufficiently thicker than the reinforcing plates 70 and 80.

[0044] The lower surface 36 of the main body 30 is abutted against the back of the ceiling board 5. A female screw 37 is formed on the lower surface 36 of the main body 30. A hole 5a is formed in the ceiling board 5 at a position that overlaps with the female screw 37.

[0045] The connector 90 is a metal ring hook, such as one made of stainless steel or aluminum alloy. The connector 90 may also be a metal J-shaped hook, L-shaped hook, C-shaped hook, shackle, clamp, hook, or cross bit, instead of a ring hook. The connector 90 has a male screw 91. The male screw 91 is inserted into a hole 5a in the ceiling board 5 and screwed into a female screw 37. The male screw 91 may be threaded to prevent loosening.

[0046] Furthermore, the number of first support pins 50 may be two or more. In other words, multiple first support pins 50 may penetrate the reinforcing plate 70, support material 10, dowel 40, and reinforcing plate 80 in a direction perpendicular to the central axis direction of the dowel 40. These first support pins 50 may be arranged at intervals in the vertical direction. The number of second support pins 60 may also be two or more. In other words, multiple second support pins 60 may penetrate the reinforcing plate 70, the main body 30, the dowel 40, and the reinforcing plate 80 in a direction perpendicular to the central axis direction of the dowel 40. These second support pins 60 may be arranged at intervals in the vertical direction.

[0047] <2. Installation method of the suspension equipment> The dowel pins 40 are fitted into the dowel holes 12 of the support material 10 and the dowel holes 32 of the main body 30, and the upper surface 31 of the main body 30 is brought into contact with the lower surface 11 of the support material 10.

[0048] The first support pin 50 is driven into the through-holes 15 and 41 from the side of the support material 10, so that the first support pin 50 penetrates the support material 10 and the dowel 40 in the width direction. The second support pin 60 is driven into the through holes 35 and 42 from the side of the support material 10, so that the second support pin 60 penetrates the support material 10 and the dowel 40 in the width direction.

[0049] The reinforcing plate 70 is placed against the sides 13 and 33 of the support material 10 and the main body 30, and the ends of the support pins 50 and 60 are inserted into the holes 71 and 72 of the reinforcing plate 70, respectively. The reinforcing plate 70 is fastened to the side 13 of the support material 10 with multiple screws 79. The reinforcing plate 70 is fastened to the side 33 of the main body 30 with multiple screws 79. The reinforcing plate 80 is placed against the sides 14 and 34 of the support material 10 and the main body 30, and the ends of the support pins 50 and 60 are inserted into the two holes in the reinforcing plate 80, respectively. The reinforcing plate 80 is fastened to the side 14 of the support material 10 with multiple screws 89. The reinforcing plate 80 is fastened to the side 34 of the main body 30 with multiple screws 89. The procedure may be modified. For example, after fixing the reinforcing plates 70 and 80 to the support material 10 and the main body 30, the first support pin 50 may be driven into the hole 71, through hole 15, through hole 41 in the reinforcing plate 70 and the hole in the reinforcing plate 80, and the second support pin 60 may be driven into the hole 72 in the reinforcing plate 70, through hole 35, through hole 42 in the reinforcing plate 70 and the hole in the reinforcing plate 80. Since the hammer or other tool used to drive in the support pins 50 and 60 will hit the reinforcing plates 70 and 80, damage to the support material 10 due to impact force is prevented.

[0050] After that, the joists 3, insulation boards 4, and ceiling boards 5 are installed. The male screw 91 of the connector 90 is passed through the hole 5a of the ceiling board 5 and fastened to the female screw 92.

[0051] <3. Summary> (1) The dowel 40 is fitted into the dowel hole 12 of the support material 10, and the first support pin 50 penetrates the dowel 40 and the support material 10 in a direction perpendicular to the central axis of the dowel 40, thereby preventing the dowel 40 from coming out of the dowel hole 12. Similarly, the second support pin 60 prevents the dowel 40 from coming out of the dowel hole 32 of the main body 30. These dowels 40, the first support pin 50 and the second support pin 60 ensure a strong connection and fixation of the main body 30 to the support material 10. In other words, the hanging device 20 is securely fixed to the support material 10.

[0052] (2) Since the cross-sectional defects of the wooden support member 10 are compensated for by the dowel 40 and the first support pin 50, a decrease in the strength of the support member 10 is unlikely to occur, and the hanger 20 is firmly fixed to the support member 10.

[0053] (3) The connection and fixing of the main body 30 to the support material 10 is achieved by inserting the dowels 40 into the dowel holes 12 and 32 and passing the support pins 50 and 60 through them. Therefore, bolting is not required to connect and fix the main body 30 to the support material 10. Thus, the main body 30 can be easily fixed to the support material 10.

[0054] (4) Since the first support pin 50 penetrates the dowel 40 and the support material 10, the exposure of the first support pin 50 is minimal. Since the second support pin 60 penetrates the dowel 40 and the main body 30, the exposure of the second support pin 60 is minimal. These factors contribute not only to improving the aesthetic design of the hanging device 20, but also to improving its fire resistance and condensation resistance.

[0055] (5) The main body 30 and the support member 10 are reinforced and protected by the reinforcing plates 70 and 80. Since the reinforcing plates 70 and 80 are located on both sides of the main body 30 and the support member 10, the main body 30 and the support member 10 are reinforced in a balanced manner from both sides. The reinforcing plates 70 and 80 contribute to the secure fixing of the suspension device 20 to the support member 10.

[0056] (6) The first support pin 50 protrudes from the side surface 13 of the support material 10 and is inserted into the hole 71 of the reinforcing plate 70, so that the first support pin 50 is supported by the reinforcing plate 70. This reduces the structural adverse effect that the first support pin 50 has on the support material 10. Inserting the first support pin 50 into the hole of the reinforcing plate 80 on the opposite side achieves a similar effect.

[0057] (7) The second support pin 60 protrudes from the side 33 of the main body 30 and is inserted into the hole 72 of the reinforcing plate 70, so that the second support pin 60 is supported by the reinforcing plate 70. This reduces the structural adverse effect that the second support pin 60 has on the main body 30. Inserting the second support pin 60 into the hole of the reinforcing plate 80 on the opposite side achieves a similar effect.

[0058] (8) The energy used from the production to the disposal of wood is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, if the building on which the support material 10 is installed is made of wood, that building contributes to the realization of a decarbonized society by promoting carbon neutrality, which makes carbon dioxide emissions virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).
