[0006] The problem to be solved by the present invention is to make it possible to securely fix a sling to a support material. [Means for solving the problem]

[0007] The following reference numerals in parentheses refer to Figures 1 and 2.

[0008] In order to solve the above problems, according to claim 1, the sling (20) is a main body (30) having an upper surface that abuts against the lower surface (11) of the support material (10); a dowel (40) fitted into a first dowel hole (12) formed in the lower surface (11) of the support material (10) and a second dowel hole (32) formed in the upper surface of the main body (30); a first support pin (50) that penetrates the dowel (40) and the support material (10) in a direction perpendicular to the axial direction of the dowel (40); a second support pin (60) that penetrates the dowel (40) and the main body (30) in a direction perpendicular to the axial direction of the dowel (40); a connector (90) provided on the main body (30); Equipped with.

[0009] According to claim 1 as described above, the dowel (40) is fitted into the first dowel hole (12), and the first support pin (50) penetrates the dowel (40) and the support material (10) in a direction perpendicular to the axial direction of the dowel (40), thereby preventing the dowel (40) from coming out of the first dowel hole (12). The dowel (40) is fitted into the second dowel hole (32), and the second support pin (60) penetrates the dowel (40) and the main body (30) in a direction perpendicular to the axial direction of the dowel (40), thereby preventing the dowel (40) from coming out of the second dowel hole (32). The dowel 40, the first support pin 50, and the second support pin 60 firmly connect and secure the main body 30 to the support 10. That is, the lifting device 20 is securely fixed to the support 10. Since the cross-sectional loss of the support material (10) is compensated for by the dowel (40) and the first support pin (50), the strength of the support material (10) is less likely to decrease, and the sling (20) is securely fixed to the support material (10). The main body 30 is connected and fixed to the support 10 by fitting the dowels 40 into the first dowel holes 12 and the second dowel holes 32 and passing the first support pins 50 and the second support pins 60 through them, so no bolt tightening work is required to connect and fix the main body 30 to the support 10. Therefore, the main body 30 can be easily fixed to the support 10. The first support pin 50 is less exposed because it penetrates the dowel 40 and the support 10. The second support pin 60 is less exposed because it penetrates the dowel 40 and the main body 30. These features not only improve the design of the sling 20, but also contribute to improved fire resistance and condensation resistance.

[0013] According to claim 3 as described above, 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 material (70), so that the first support pin (50) is supported by the reinforcing material (70). This reduces the adverse effect of the first support pin (50) on the strength of the support material (10).

[0014] According to claim 4, in the sling (20) according to claim 2, The reinforcement (70) has a hole (72), The second support pin (60) protrudes from the side surface (33) of the main body (30) and is inserted into the hole (72) of the reinforcing member (70).

[0015] According to claim 4 as described above, the second support pin (60) protrudes from the side surface (33) of the main body (30) and is inserted into the hole (72) of the reinforcing material (70), so that the second support pin (60) is supported by the reinforcing material (70). This reduces the adverse effect of the second support pin (60) on the strength of the main body (30).

[0016] According to claim 5, the sling (20) according to claim 2, 3 or 4, a second reinforcement (80) fixed to second sides (14 and 34) of the body (30) and the support (10) opposite the sides (13 and 33) of the body (30) and the support (10); Further provided with:

[0017] According to claim 5, the main body 30 and the support 10 are reinforced and protected by the second reinforcing member 80. Since the reinforcing member 70 and the second reinforcing member 80 are located on both sides of the main body 30 and the support 10, the main body 30 and the support 10 are reinforced in a balanced manner from both sides. The second reinforcing member 80 contributes to firmly fixing the sling 20 to the support 10.

[0018] According to claim 6, in the hanging device (20) according to claim 5, The second reinforcement (80) has holes, The first support pin (50) protrudes from the second side (14) of the support (10) and is inserted into the hole in the second reinforcement (80).

[0019] According to claim 6 as described above, the first support pin (50) protrudes from the second side surface (14) of the support material (10) and is inserted into the hole of the second reinforcing material (80), so the first support pin (50) is supported by the second reinforcing material (80). This reduces the adverse effect of the first support pin (50) on the strength of the support material (10).

[0020] According to claim 7, in the hanging device (20) according to claim 5, The reinforcement (70) has holes, The second support pin (60) protrudes from the second side (34) of the body (30) and is inserted into the hole in the second reinforcement (80).

[0021] According to claim 7, the second support pin (60) protrudes from the second side surface (34) of the main body (30) and is inserted into the hole of the second reinforcing member (80), so the second support pin (60) is supported by the second reinforcing member (80). This reduces the adverse effect of the second support pin (60) on the strength of the main body (30). [Effects of the Invention]

[0022] In the present invention, the sling is securely fixed to the support. [Brief explanation of the drawings]

[0023] [Figure 1] FIG. 1 is a side view of the sling. [Figure 2] FIG. 2 is a vertical cross-sectional view taken along line II-II shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0024] Hereinafter, embodiments will be described with reference to the drawings. 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. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples in the drawings.

[0025] <1. Lifting equipment> Fig. 1 is a side view of the sling device, and Fig. 2 is a vertical cross-sectional view taken along line II-II in Fig. 1, viewed in the direction of the arrows.

[0026] The ceiling on which the suspending device 20 is installed is a ceiling installed above a space in a building, such as an inner balcony, an outdoor living room, a living room, a dirt floor, an entrance hall, an entrance porch, a storage room, a washroom, a stairwell, or a corridor. The space below the ceiling is an indoor or outdoor space of the building. The building is a wooden building, a reinforced concrete building, a steel-reinforced concrete building, or a steel-framed building. The building may have a wall structure, a frame structure, or both. A wall structure refers to a building in which the weight of the building itself, the load of the load, and seismic forces are supported by walls. A frame structure refers to a building in which the weight of the building itself, the load of the load, and seismic forces are supported by columns and beams. The building may be constructed using a panel construction method, a frame construction method, a frame panel construction method, a frame wall construction method, or a combination of two or more of these methods. In one example, the building is a wooden building with a wall structure constructed using a wood panel adhesive construction method, which is a type of panel construction method, and the main components of the building, such as the walls, floors, ceilings, and roof, are made of wood panels. The wood panel has a wooden frame formed by assembling four stiles into a rectangular frame, wooden face plates attached to the front and back surfaces of the frame, and wooden auxiliary crosspieces arranged vertically, horizontally, or vertically and horizontally inside the frame. The wood panel may also have a heat insulating material filled inside the rectangular frame.

[0027] The ceiling has a support material 10, a joist 3, an insulating board 4, a ceiling board 5 and a hanging fixture 20.

[0028] The support material 10 is, for example, wood such as a beam, a frame, or a ceiling joist. The beam may be, for example, a main beam, a sub-beam, a flint beam, or a rafter. The term "beam" here includes a girder. The frame may constitute a frame for a wood 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 load, and earthquake forces.

[0029] The joists 3 are suspended from the support members 10 by hanging members and, if necessary, joist supports. The joists 3 are installed horizontally. Heat-insulating boards 4 are laid on the joists 3. Ceiling boards 5 are attached below the joists 3.

[0030] The ceiling board 5 has a hole 5a that passes through the ceiling board 5 from top to bottom. The hole 5a is located directly below the hanger 20.

[0031] The sling 20 is a ceiling-hanging device that is installed on a ceiling. The sling 20 is used to suspend objects such as hammocks, clotheslines, play equipment, projection screens, banners, ropes, or wires. The sling 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 shaped like a rectangular pillar. The main body 30 is made of wood. However, the main body 30 may also be made of a metal material such as stainless steel or an aluminum alloy. The top surface 31 of the main body 30 is in surface contact with the bottom surface 11 of the support 10. The main body 30 hangs down from the bottom surface 11 of the support 10. The width from the side surface 33 of the main body 30 to the opposite side surface 34 is equal to the width from the side surface 13 to the opposite side surface 14 of the support 10. Both side surfaces 33, 34 of the main body 30 are flush with both side surfaces 13, 14 of the support 10, respectively.

[0033] Dowel holes 32 and 12 are formed in 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 the dowel holes 32 and 12. The dowels 40 are made of a metal material such as stainless steel or an aluminum alloy.

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

[0035] The through hole 42 penetrates the upper part of the dowel 40 in a direction perpendicular to the central axis of the dowel 40. Meanwhile, the through hole 35 penetrates in the width direction from the side surface 33 of the main body 30 to the side surface 34 via the dowel hole 32. The through holes 35 and 42 are continuous, and a second support pin 60 made of metal such as stainless steel or aluminum alloy is fitted into these through holes 35, 42. The insertion of the second support pin 60 into the through holes 35, 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, which contribute to preventing the second support pin 60 from coming out of the through holes 35, 42. The main body 30 is fixed to the lifting device 20 by a dowel 40 and support pins 50 and 60 .

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

[0037] A reinforcing plate 70 made of a metal such as stainless steel or aluminum alloy is in 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 with a plurality of screws 79. Two holes 71, 72 are formed in the reinforcing plate 70, and the ends of the support pins 50, 60 are inserted into the holes 71, 72, respectively.

[0038] The holes 71, 72 may not be formed in the reinforcing plate 70, and the ends of the support pins 50, 60 may not protrude from both ends of the through-hole 15, but may abut against the reinforcing plate 70. Such a reinforcing plate 70 contributes to preventing the support pins 50, 60 from coming out.

[0039] A reinforcing plate 80 made of a metal such as stainless steel or aluminum alloy is in 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 with a plurality of screws 89. Two holes are formed in the reinforcing plate 80, and the ends of the support pins 50, 60 are inserted into the two holes, respectively.

[0040] Note that holes may not be formed in the reinforcing plate 80, and the ends of the support pins 50, 60 may not protrude from both ends of the through-hole 35, but may abut against the reinforcing plate 80. Such a reinforcing plate 80 contributes to preventing the support pins 50, 60 from coming out.

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

[0042] The reinforcing plates 70, 80 reinforce the mutual fixation of the suspending tool 20 and the main body 30 by the dowel 40 and the support pins 50, 60. The reinforcing plates 70, 80 prevent the main body 30 from rattling.

[0043] While the reinforcing material is plate-shaped like the reinforcing plates 70 and 80, the reinforcing material may be in the form of a block that is 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. An internal thread 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 overlapping the internal thread 37.

[0045] The connector 90 is a metal ring hook made of stainless steel or aluminum alloy. Instead of a ring hook, the connector 90 may be a metal J-hook, L-hook, C-hook, shackle, clamp, hook, or cross bit. The connector 90 has a male thread 91. The male thread 91 is inserted into the hole 5a of the ceiling board 5 and screwed into the female thread 37. The male thread 91 may be machined to have a locking mechanism.

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

[0047] <2. How to install the lifting device> The dowel 40 is fitted into the dowel hole 12 of the support material 10 and the dowel hole 32 of the main body 30 , and the upper surface 31 of the main body 30 is placed against the lower surface 11 of the support material 10 .

[0048] The first support pin 50 is driven into the through-hole 15 and the through-hole 41 from the side of the support material 10, and 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-hole 35 and the through-hole 42 from the side of the support material 10, and 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 side surfaces 13, 33 of the support material 10 and the main body 30, and the ends of the support pins 50, 60 are inserted into the holes 71, 72 of the reinforcing plate 70, respectively. The reinforcing plate 70 is fastened to the side surface 13 of the support material 10 with a plurality of screws 79. The reinforcing plate 70 is fastened to the side surface 33 of the main body 30 with a plurality of screws 79. The reinforcing plate 80 is placed against the side surfaces 14, 34 of the support material 10 and the main body 30, and the ends of the support pins 50, 60 are inserted into the two holes in the reinforcing plate 80. The reinforcing plate 80 is fastened to the side surface 14 of the support material 10 with a plurality of screws 89. The reinforcing plate 80 is fastened to the side surface 34 of the main body 30 with a plurality of screws 89. The procedure may be changed. For example, after the reinforcing plates 70, 80 are fixed to the support material 10 and the main body 30, the first support pin 50 may be driven into the hole 71, the through hole 15, the through hole 41 of the reinforcing plate 70, and the hole of the reinforcing plate 80, and the second support pin 60 may be driven into the hole 72, the through hole 35, the through hole 42 of the reinforcing plate 70, and the hole of the reinforcing plate 80. Because a hammer or the like used to drive the support pins 50, 60 hits the reinforcing plates 70, 80, damage to the support material 10 due to impact force is prevented.

[0050] Then, the rough frame 3, the heat insulating board 4 and the ceiling board 5 are installed. The male screw 91 of the connector 90 is passed through the hole 5 a 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, 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. The dowel 40, the first support pin 50, and the second support pin 60 firmly connect and secure the main body 30 to the support material 10. In other words, the lifting device 20 is securely fixed to the support material 10.

[0052] (2) Since the cross-sectional loss of the wooden support member 10 is compensated for by the dowel 40 and the first support pin 50, the strength of the support member 10 is less likely to decrease, and the sling 20 is firmly fixed to the support member 10.

[0053] (3) The main body 30 is connected and fixed to the support material 10 by fitting the dowels 40 into the dowel holes 12, 32 and passing the support pins 50, 60 through them, so no bolt tightening work is required to connect and fix the main body 30 to the support material 10. Therefore, the main body 30 can be easily fixed to the support material 10.

[0054] (4) The first support pin 50 is less exposed because it penetrates the dowel 40 and the support material 10. The second support pin 60 is less exposed because it penetrates the dowel 40 and the main body 30. These facts contribute to improving not only the design of the sling device 20 but also its fire resistance and condensation resistance.

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

[0056] (6) Because 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, the first support pin 50 is supported by the reinforcing plate 70. This reduces the adverse effect that the first support pin 50 has on the strength of the support material 10. The same effect can be achieved by inserting the first support pin 50 into the hole of the reinforcing plate 80 on the opposite side.

[0057] (7) Because the second support pin 60 protrudes from the side surface 33 of the main body 30 and is inserted into the hole 72 of the reinforcing plate 70, the second support pin 60 is supported by the reinforcing plate 70. This reduces the adverse effect that the second support pin 60 has on the strength of the main body 30. The same effect can be achieved by inserting the second support pin 60 into the hole of the reinforcing plate 80 on the opposite side.

[0058] (8) The energy used from the production to the disposal and discarding of wood is less than the energy used from the production to the disposal and discarding of metal or concrete materials. Therefore, if the building in which the support material 10 is installed is made of wood, the building will contribute to the realization of a carbon-neutral society by promoting carbon neutrality, which essentially reduces carbon dioxide emissions to zero, and to the achievement of the Sustainable Development Goals (SDGs). If the main body 30 is made of wood, the lifting device 20 will contribute to the realization of a carbon-neutral society and the achievement of the SDGs.

[0059] (9) The above-disclosed embodiments have been made for the purpose of illustration and example only, and are not intended to limit the scope of the present invention, which should be interpreted by the terms of the claims. [Explanation of symbols]
