[0011] <Morning glory device 1> The morning glory device 1 of the present invention will be described below with reference to the drawings. As shown in Figure 1, the morning glory device 1 according to one embodiment of the present invention comprises a frame body 2 attached to a vertical pipe 5 of temporary scaffolding 50 by an upper mounting bracket 6, and a diagonal member 3 attached to the vertical pipe 5 by a lower mounting bracket 7 to support the frame body 2 from below. The lower mounting bracket 7 is attached to the vertical pipe 5 below the upper mounting bracket 6. 1 shows a stored state (indicated by a dashed line) in which the frame body 2 and diagonal members 3 are placed along the vertical pipes 5 of the temporary scaffolding 50 in a vertical position, and a used state in which the frame body 2 is tilted diagonally upward from the vertical pipes 5. In the used state, the frame body 2 is held by a hanging member 105 such as a rope.

[0012] As shown in Figure 2(a), the frame body 2 is composed of an upper frame 21, a lower frame 22, and two vertical frames 23, 23 connecting them, and holds a panel 4 within the frame. The panel 4 is stretched within the frame body 2 and has the function of catching falling objects. The lower frame 22 has mounting fixtures 24 at both ends for attaching to the upper mounting bracket 6. Furthermore, as shown in Figure 2(b), the diagonal member 3 has a first mounting fixture 31 at its upper end that is attached to the vertical frame 23 of the frame body 2, and a second mounting fixture 32 at its lower end that is attached to the lower mounting bracket 7. The materials for the frame body 2 and the diagonal members 3 are not particularly limited, but a lightweight and strong material is preferred, for example, a metal such as aluminum or steel.

[0013] Fig. 3 shows the state in which the upper mounting bracket 6 and the lower mounting bracket 7 are attached to the vertical pipe 5 of the temporary scaffolding 50. Fig. 4(a) is an enlarged front view of part A in Fig. 3 (the state in which the upper mounting bracket 6 is attached), and Fig. 4(b) is a cross-sectional view taken along line XX in Fig. 3. Fig. 5(a) is a partial front view showing the upper mounting bracket 6 in Fig. 4(a) excluding the first clamp part 61, and Fig. 5(b) is a plan view thereof.

[0014] 4(a) and (b), the upper mounting bracket 6 includes a first clamp portion 61 attached to the vertical pipe 5, a first U-shaped portion 62 to which the first clamp portion 61 is attached, and a first frame holding portion 63 attached to the top of the first U-shaped portion 62. A plate-shaped first connecting portion 64 is interposed between the first U-shaped portion 62 and the first frame holding portion 63, connecting the first U-shaped portion 62 and the first frame holding portion 63. The connection is made by, for example, welding.

[0015] The first U-shaped portion 62 has a U-shape with abutment portions 621 attached to both ends of a plate-like clamp attachment portion 620. A screw hole 620H is drilled in the center of the clamp attachment portion 620. A bolt 8 is inserted through a screw insertion hole (not shown) provided in the bottom portion 611 of the first clamp portion 61 and threaded into the screw hole 620H to fix the first clamp portion 61 to the clamp attachment portion 620. Therefore, the first clamp portion 61 is detachable and can be easily replaced if it becomes worn. In addition, since the tip of the bolt 8 protrudes from the screw hole 620H, a notch 9 is formed in the first connecting portion 64 at a location adjacent to the screw hole 620H, and the tip of the bolt 8 protrudes into this notch 9.

[0016] The contact portions 621 attached to both ends of the clamp attachment portion 620 are plate-shaped and have trapezoidal recesses 10 at their bottoms (see FIG. 5(b)). As shown in FIGS. 4(a) and (b), when the first clamp portion 61 is attached to the vertical pipe 5, a part of the vertical pipe 5 enters the recess 10 of each contact portion 621 and abuts against the inner surface of the recess 10. At this time, it is sufficient that the recess 10 is in contact with the vertical pipe 5 at either the bottom or both sides, but it is preferable that the recess 10 is in contact with the pipe 5 at both the bottom and both sides. In this way, the abutment portions 621 abut against the vertical pipes 5 above and below the first clamp portion 61, respectively, so that even if the first clamp portion 61 becomes loose due to long-term use, construction vibrations, impacts, etc., or even if the first clamp portion 61 becomes worn due to long-term use, the frame body 2 will not rotate in the vertical direction and tilt. The recess 10 is not limited to a trapezoidal shape, and may be, for example, a triangular shape, a regular square shape, an arc shape, etc. When the recess 10 is arc-shaped, the outer peripheral surface of the vertical pipe 5 may abut almost the entire surface of the arc-shaped recess 10.

[0017] The first frame body holding portion 63 has frame body mounting portions 631, 631 at both ends for mounting one end of the bottom frames 22 of two adjacent frame bodies 2, respectively. These frame body mounting portions 631, 631 are formed by fixing a small U-shaped portion 63b into a large U-shaped portion 63a by welding or the like. The large U-shaped portion 63a and the small U-shaped portion 63b each have a pin insertion hole 12 for inserting a gravity pin 11. The gravity pin 11 is used to mount the bottom frame 22 of the frame body 2 to the frame body mounting portion 631. The mounting method will be described in detail later. The gravity pin 11 is connected to the frame body holding portion 63 by a string material 13 such as a wire to prevent it from being lost (see FIG. 4(b)).

[0018] Next, the lower mounting bracket 7 will be described with reference to Figures 6(a) and 6(b) and Figures 7(a) and 7(b). Figure 6(a) is an enlarged front view of part B in Figure 3 (the mounted state of the lower mounting bracket 7), and Figure 6(b) is a cross-sectional view taken along line YY. Figure 7(a) is a partial front view of the lower mounting bracket 7 in Figure 6(a) excluding the second clamp part 71, and Figure 7(b) is a side view thereof.

[0019] 6(a) and 6(b), the lower mounting bracket 7 includes a second clamp portion 71 attached to the vertical pipe 5, a second U-shaped portion 72 to which the second clamp portion 71 is attached, and a diagonal member holding portion 73 attached to the upper part of the second U-shaped portion 72. A plate-shaped second connecting portion 74 is interposed between the second U-shaped portion 72 and the diagonal member holding portion 73, connecting the second U-shaped portion 72 and the diagonal member holding portion 73. The connection is made by, for example, welding or the like.

[0020] The second U-shaped portion 72 has the same structure and function as the first U-shaped portion 62. Therefore, in the following description, the same members and parts as those of the first U-shaped portion 62 may be designated by the same reference numerals. The second U-shaped portion 72 has a U-shaped shape with abutment portions 721 attached to both ends of a plate-like clamp attachment portion 720. A screw hole 720H ​​is drilled in the center of the clamp attachment portion 720. A bolt 8 is inserted through a screw insertion hole (not shown) provided in the bottom 711 of the second clamp portion 71 and threaded into the screw hole 720H ​​to fix the second clamp portion 71 to the clamp attachment portion 720. Therefore, the second clamp portion 71 is detachable and can be easily replaced if the second clamp portion 71 becomes worn. Further, a notch 9 is formed in the second connecting portion 74 at a location adjacent to the screw hole 720H, and the tip of the bolt 8 projects into this notch 9.

[0021] The contact portions 721 attached to both ends of the clamp attachment portion 720 are plate-shaped and have trapezoidal recesses 10 at their bottoms (FIG. 7(b)). As shown in FIGS. 6(a) and 6(b), when the second clamp portion 71 is attached to the vertical pipe 5, a portion of the vertical pipe 5 enters the recess 10 of each contact portion 621 and abuts against the inner surface of the recess 10. At this time, it is sufficient for the recess 10 to be in contact with the vertical pipe 5 at either the bottom or both sides, but it is preferable for the recess 10 to be in contact with the pipe 5 at both the bottom and both sides of the recess 10. In this way, the contact portions 621 abut against the vertical pipe 5 above and below the first clamp portion 61, respectively, so that the frame body 2 does not rotate up and down and tilt as described above. As mentioned above, the recess 10 is not limited to a trapezoidal shape, but may be, for example, a triangular shape, a square shape, an arc shape, or the like.

[0022] The diagonal member holding portion 73 is attached to the second U-shaped portion 72 via the second connecting portion 74, and has diagonal member mounting portions 731 at both ends to which the lower ends of the diagonal members 3 are attached. As shown in Figure 6(b), the diagonal member holding portion 73 in this embodiment is made of a U-shaped plate material, and has diagonal member mounting portions 731 at both ends. This allows the lower ends of two adjacent diagonal members 3, 3 to be attached. The diagonal member mounting portion 731 is composed of a gravity pin 15, and the rear end of the gravity pin 15 is inserted into the through holes 14 provided at both ends of the diagonal member holding portion 73 and fixed by welding or the like.

[0023] Next, the assembly procedure for the morning glory device 1 of this embodiment will be described. First, as shown in Figure 8, the upper mounting brackets 6 are attached to the adjacent vertical pipes 5, 5 of the temporary scaffolding 50, and both ends of the lower frame 22 are attached to these upper mounting brackets 6. The upper mounting brackets 6 are attached to the vertical pipes 5 using the first clamp parts 61, as described above.

[0024] 9 shows a method for attaching the lower frame 22 to the upper mounting bracket 6. That is, as shown in FIG. 9, the L-shaped mounting fixture 24 attached to the underside of the lower frame 22 is inserted into one of the frame mounting portions 631 of the first frame holding portion 63, and the through-holes (not shown) formed in the mounting fixture 24 are aligned with the pin insertion holes 12, 12 formed in the large U-shaped portion 63a and the small U-shaped portion 63b shown in FIG. 4(b), and the gravity pin 11 is inserted to attach the lower frame 22 to the upper mounting bracket 6. The screws 16 on the end face of the lower frame 22 are removed in advance. In addition, a protrusion 17 made of a square pipe or the like is provided on the upper surface of the lower frame 22 and is used to assemble the frame 2. 9 shows a method for attaching one end of the lower frame 22 (part C in FIG. 8), but the other end is attached in the same manner.

[0025] Figures 10(a) to 10(d) show the steps for assembling the frame body 2. As shown in Figure 10(a), the face material 4 that constitutes the frame body 2 is endless and spans between two support materials 18, 18. The face material 4 is preferably a flexible sheet made by bonding a fiber sheet and a synthetic resin together, and a specific example is a tarpaulin made by bonding vinyl chloride to a polyester fabric.

[0026] The support material 18 is a rod-shaped or cylindrical member, and after the face material 4 is spanned between the two support materials 18, 18 as shown in Figure 10(a), it is removably inserted into the vertical frames 23, 23, respectively, as shown in Figure 10(b). The vertical frame 23 has a lip groove shape and has a hanger mounting fixture 107 for attaching a hanger 105. There are no particular restrictions on the shape of the support material 18, but it is preferably lightweight and strong, and examples of the material include aluminum, steel, FRP (fiber reinforced plastic), etc.

[0027] The installation procedure will be explained below. (I) As shown in FIG. 10(a), first, an endless face member 4 is placed between two support members 18, 18. (II) Next, as shown in Figure 10(b), the support members 18, 18 with the face material 4 attached are inserted into the vertical frames 23, 23, respectively. The support members 18, 18 are inserted into the protruding portions 17, such as square pipes, erected on both ends of the bottom frame 22, and the vertical frame 23 and the bottom frame 22 are fixed with screws 16. The diagonal members 3 may be connected to the vertical frame 23 in advance. (III) Next, as shown in Figure 10(c), the upper frame 21 with the protrusion 17' facing downward, similar to when it was erected on the lower frame 22, is inserted from the top of the support material 18 and fixed from the side with screws 16 to obtain a frame body 2 holding the surface material 4 (Figure 10(d)). The frame body 2 obtained in FIG. 10(d) has the lower frame 22 attached to the vertical pipes 5 of the temporary scaffolding 50 by the upper mounting brackets 6, as shown in FIGS.

[0028] Next, the procedure for attaching the diagonal member 3 to the frame body 2 and the temporary scaffolding 50 will be described. As shown in FIG. 2(b), the diagonal member 3 has a first mounting fixture 31 attached to the vertical frame 23 of the frame body 2 at its upper end, and a second mounting fixture 32 at its lower end. As shown in FIG. 11, the first mounting fixture 31 has a gravity pin 19 fixed at its rear end by welding or the like. A mounting fixture 20 with a through-hole is formed in the vertical frame 23 of the frame body 2, and the diagonal member 3 is attached by inserting the gravity pin 19 into the through-hole.

[0029] The second mounting fixture 32 is made up of a plate material having a through hole 321 protruding from the lower end surface of the diagonal member 3. The lower end of the diagonal member 3 is moved toward the lower mounting bracket 7 attached to the vertical pipe 5 of the temporary scaffolding 50, and the diagonal member mounting portion 731 (gravity pin 15) provided on the diagonal member holding portion 73 of the lower mounting bracket 7 is inserted into the through hole 321, and the lower end of the diagonal member 3 is attached.

[0030] Finally, the hanging material 105 is attached to the hanging material fixture 107 of the vertical frame 23, completing the installation of the frame body 2. When removing the morning glory device 1, the above-mentioned procedure can be carried out in reverse.

[0031] <Balloon device 1´ at corner D> The morning glory device 1 described above is used in the straight section of the temporary scaffolding 50. Hereinafter, with reference to Figures 12, 13A, 13B, 14A, 14B, the morning glory device 1' to be attached to the corner section D of the temporary scaffolding 50 will be described.

[0032] As shown in Figure 12, the morning glory device 1' consists of multiple support members 25, one end of which is fixed to a corner portion D of a temporary scaffolding 50, arranged in a fan shape and protruding diagonally upward from the temporary scaffolding 50, and a face member 41 stretched across each support member 25. The face member 41 should preferably be made of a flexible sheet material similar to the face member 4 described above. This allows the morning glory device 1' at the corner portion D to be folded, making it convenient for storage and transportation. Also, in Figure 12, the part indicated by arrow E indicates the attachment position of the upper end of the diagonal member 3. Components that are the same as those used in the morning glory device 1 described above are given the same reference numerals, and detailed explanations will be omitted.

[0033] Fig. 13A is a plan view showing upper corner mounting bracket 26 used in corner portion D, and Fig. 13B is a perspective view showing upper corner mounting bracket 26 in Fig. 13A without first clamp portion 61. In upper corner mounting bracket 26 shown in Figs. 13A and 13B, first clamp portion 61, first U-shaped portion 62 having clamp mounting portion 620 and abutment portion 621, bolt 8 that secures first clamp portion 61 and screws into threaded hole 620H formed in clamp mounting portion 620, and first connecting portion 64 having notch portion 9 are the same as the components shown in Figs. 4 and 5 described above.

[0034] A first support material holding portion 261 for supporting multiple support materials 25 is joined to the first connecting portion 64. The first support material holding portion 261 has frame body mounting portions 261A, 261B at both ends for respectively mounting one end of the lower frame 22 of the frame body 2 in the straight portion adjacent to the upper corner mounting fitting 26, and further has multiple support material mounting portions 261C protruding between them at predetermined intervals. Pin insertion holes 12 are formed in the frame body mounting portions 261A, 261B and the support material mounting portion 261C, respectively.

[0035] In addition, gravity pins 11 connected by string material 13 are arranged near the frame body mounting portions 261A, 261B, and the mounting fixtures 24 (see Figure 9) of the lower frame 22 are inserted into each frame body mounting portion 261A, 261B, and the gravity pins 11 are inserted into the pin insertion holes 12 to connect them to the frame body 2 of the adjacent straight section. The lower end of the support member 25 is attached to the support member attachment portion 261C. To attach the support member 25, for example, a first attachment tool 31 similar to the first attachment tool 31 attached to the upper end of the diagonal member 3 shown in FIG. 11 is attached to the lower end of the support member 25, and the gravity pin 19 similar to that attached to the first attachment tool 31 is inserted into the pin insertion hole 12 to attach the lower end of the support member 25.

[0036] The corner lower mounting bracket 27 shown in Fig. 14A is used to attach the diagonal member 3 to the corner portion D. Fig. 14A is a plan view showing the corner lower mounting bracket 27 used in the corner portion D, and Fig. 14B is a perspective view showing the corner lower mounting bracket 27 in Fig. 14A without the second clamp portion 71.

[0037] In the corner bottom mounting bracket 27 shown in Figures 14A and 14B, the second clamp portion 71; the second U-shaped portion 72 having the clamp mounting portion 720 and the abutment portion 721; the bolt 8 for fixing the second clamp portion 71 which screws into the screw hole 720H ​​formed in the clamp mounting portion 720; and the second connecting portion 74 having the cutout portion 9 are the same as the components shown in Figures 6 and 7 described above.

[0038] A second diagonal member holding portion 271 for supporting multiple diagonal members 3 is attached to the second connection portion 74. The second diagonal member holding portion 271 has diagonal member mounting portions 271A and 271B at both ends for mounting the lower ends of the diagonal members 3 that support the frame body 2 in the straight section adjacent to the corner lower mounting bracket 27, and further has multiple diagonal member mounting portions 271C protruding at predetermined intervals between them for mounting the lower ends of the diagonal members 3 in the corner portion D. The diagonal member mounting portions 271A, 271B, and 271C each have a pin insertion hole 12. The diagonal member mounting portions 271A, 271B, and 271C are formed by fixing the base ends of gravity pins 15 to the second diagonal member holding portion 271 by welding or the like. The diagonal member mounting portions 271A, 271B, and 271C are mounted in the same manner using a mounting fixture (not shown) similar to the second mounting fixture 32 for mounting the lower end of the diagonal member 3 of the straight section described based on Figure 11.

[0039] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various improvements and modifications are possible within the scope of the present disclosure. For example, instead of flexible sheet materials, metal plates such as aluminum or steel, or panels such as fiber-reinforced plastic plates may be used as the face members 4 and 41. Also, while folding gravity pins 11, 15, and 19 are used in the above embodiments, spring-type gravity pins may also be used. Furthermore, instead of gravity pin 15, other mounting means, such as a pin that can rotatably hold the lower end of diagonal member 3, may be used. [Explanation of symbols]
