Description

Technical Field

[0001] The present invention relates to a morning glory device installed on a temporary scaffold to receive falling objects at a building construction site or the like.

Background Art

[0002] Conventionally, a morning glory device has been installed on a temporary scaffold at a construction site or the like to receive falling objects such as materials and tools that have fallen from above the temporary scaffold. The morning glory device includes a frame body that projects obliquely upward from the temporary scaffold, and a surface material such as a sheet material or a panel material for receiving falling objects is attached inside the frame body. The lower frame of the frame body is attached to the temporary scaffold. However, if there is a gap between the temporary scaffold and the lower frame of the frame body, even small falling objects may fall onto a road or the like through such a gap. Therefore, conventionally, it has been proposed to attach a shielding plate for closing the gap between the temporary scaffold and the lower frame of the frame body.

[0003] Patent Document 1 describes a morning glory device in which an extension plate (shielding plate) is attached to the lower frame of the frame body via a hinge to close the above gap (paragraphs

[0063] to

[0065] ). Since the extension plate is attached to the lower frame via a hinge, the extension plate can be rotated onto the lower frame during non-use, storage, transportation, etc.

[0004] Patent Document 2 describes a fall prevention device adapted to a morning glory device. This fall prevention device includes a fixing member fixed to the base end portion (corresponding to the above lower frame) of the falling object receiving device, and a shielding member (shielding plate) extending from the fixing member toward the temporary scaffold. The shielding member is pivotally connected to the fixing member by a plurality of hinges so that, during non-use, the shielding member can be rotated toward the fixing member and configured to be overlapped on the fixing member. In Patent Document 2, by making a unit in which the shielding member is overlapped on the fixing member, it is possible to retrofit the morning glory device (paragraph

[0042] ).

Best Mode for Carrying Out the Invention

[0013] Hereinafter, an embodiment of the morning glory device of the present invention will be described based on FIGS. 1 to 5. As shown in FIG. 1, the morning glory device 1 according to an embodiment of the present invention is mainly installed on a temporary scaffold at the site of the construction or repair work of mid-rise buildings such as buildings and condominiums to receive falling objects such as materials and tools. It is fixed at one end to the support column 2 of the temporary scaffold and protrudes obliquely upward, and includes a frame body 5 and a sheet material 10 (surface material) stretched in the frame body 5. The frame body 5 is composed of a vertical frame 51, a lower frame 52, and an upper frame 53.

[0014] As shown in FIG. 1, a plurality of frame bodies 5 to which the sheet material 10 is attached are arranged side by side on the outer surface of the temporary scaffold, and protrude obliquely upward from the temporary scaffold during use. The vertical frame 51, the lower frame 52, and the upper frame 53 forming the frame body 5 have a grooved cross-sectional shape. The vertical frame 51 is provided with a hanging fitting 41 for connecting a hanging material 4 for holding the frame body 5 from above on the upper surface, and support member attachment fittings 33, 34 for attaching a support member 3 for supporting the frame body 5 from below are provided on the lower surface. The frame body 5 is attached to the outer surface of the temporary scaffold by a frame fixing fitting 15. The material of such a frame body 5 is not particularly limited, but a lightweight and strong material is preferable. For example, metals such as aluminum and steel are preferable.

[0015] As shown in FIGS. 2(a) and (b), the frame fixing fitting 15 fixes the frame attachment fitting 17 and two frame rotating fittings 19 sandwiched therebetween by inserting through the respective through holes 20 with pins 18, so that the frame bodies 5 can be rotated in the vertical direction with an appropriate gap between them. The frame fixing bracket 15 that connects the frame 5 to the support column 2 of the temporary scaffolding can be composed of, for example, a clamp 16 installed between adjacent frame 5, 5 and fixed to the support column 2, a U-shaped frame mounting bracket 17 attached to the clamp 16 and having a through hole 20, and a frame rotating bracket 19 that is rotatably connected to the frame holding bracket 17 by a pin 18. This frame rotating bracket 19 is an L-shaped metal plate attached to both ends of the frame 5 and has a through hole 20 on the shorter side through which the pin 18 is inserted. The frame mounting bracket 17 and the frame rotation brackets 19 of two adjacent frames 5, 5 are fixed together with pins 18. At this time, adjacent frames 5, 5 have a predetermined gap (for example, a gap of 29 cm). This gap is to prevent adjacent frames from coming into contact with each other and being damaged during strong winds or the like.

[0016] Returning to Figure 1, the sheet material 10 is stretched within the frame 5 and serves to catch falling objects. The sheet material 10 is stretched between two vertical frames 51, 51. As the sheet material 10, for example, a flexible sheet made by laminating a fiber sheet and a synthetic resin can be used, specifically a tarpaulin made by laminating polyvinyl chloride resin onto polyester fabric. The morning glory apparatus 1 with the sheet material 10 attached has the advantage of being lightweight and easy to install, carry, and store. In Figures 2(a) and 2(b), reference numeral 54 denotes square pipes erected at both ends of the lower frame 52a. A rectangular support member (not shown) covered with sheet material 10 is inserted into the square pipes 54 and attached. Square pipes are also provided on the upper frame 53, and the support member is fixed and held in place by both square pipes. A morning glory apparatus using sheet material 10 as a surface material is described, for example, in Utility Model Registration No. 3194130.

[0017] In this embodiment, a gap shielding plate 6, as shown in Figure 3, is provided to close the gap 11 (see Figure 5) that occurs between the lower frame 52 of the frame body 5 and the outer surface of the temporary scaffolding. The gap shielding plate 6 is a flat plate with approximately the same length as the lower frame 52 and is made of a metal plate such as an aluminum plate or a steel plate. The gap shielding plate 6 is connected to the lower frame 52 by a connecting member 7. The connecting member 7 has one end attached to the gap shielding plate 6 and the other end attached to the lower frame 52, and is flexible and bendable.

[0018] Examples of flexible and bendable connecting material 7 include leather, cloth, rubber, synthetic resin, or composite sheet material made by laminating two or more of these materials. The connecting material 7 has the form of a sheet and, as shown in Figure 3, is arranged across the lower frame 52 and the gap shielding plate 6 and is fixed by fixing members 8 such as rivets. The connecting material 7 may be placed in just one location in the center, for example, but it is preferable that it be placed in multiple locations along the longitudinal direction of the lower frame 52 and the gap shielding plate 6 at appropriate intervals.

[0019] Figure 4(a) is a side view of the gap shielding device shown in Figure 3, in which the gap shielding plate 6 is suspended from the lower frame 52. As described above, the connecting member 7 is flexible and can be bent, so the connecting member 7 can be bent as shown by the arrow in Figure 4(a), allowing the gap shielding plate 6 to rotate freely. Figure 4(b) shows the gap shielding plate 6 rotated to a position facing the side surface 52a of the lower frame 52. In other words, Figure 4(b) shows the stored state of the gap shielding plate 6.

[0020] In the storage state where the gap shielding plate 6 faces the side surface 52a of the lower frame 52, a retaining member 9 is provided on the gap shielding plate 6 for detachably holding the gap shielding plate 6. This retaining member 9 consists of an arc-shaped curved elastic member 91 and a soft material 92 arranged on the outer surface of the elastic member 91, with one end integrally fixed together with the elastic member 91 by a rivet or the like. As the elastic member 91, elastic synthetic resins or rubber materials can be used. As a specific example of the elastic member 91, a member with a semicircular cross-section obtained by cutting a pipe made of polyvinyl chloride resin, rubber, etc. in half axially can be used. If one end of the member in the circumferential direction is fixed to the gap shielding plate 6, the gap shielding plate 6 can be held in place by pressing it against the side surface 52a of the lower frame 52 with a strong elastic force or biasing force, and it can also be easily removed. As the soft material 92, a member similar to the connecting member 7 described above can be used. This soft material 92 reinforces the holding function of the elastic member 91 and should be used as needed.

[0021] Figure 5 is a side view showing the gap shielding device shown in Figure 3 in use. As shown in the figure, in order to close the gap 11 that occurs between the lower frame 52 of the frame 5 and the outer surface 102 of the temporary scaffolding, the retaining member 9 is pushed open from the stored state shown in Figure 4(b), the gap shielding plate 6 is opened, and it is rotated downward so that the tip of the gap shielding plate 6 comes into contact with the outer surface 102 of the temporary scaffolding. This allows the gap shielding plate 6 to prevent objects falling from above from passing through the gap 11, thereby increasing safety. Incidentally, depending on the site, protective frames or soundproofing panels may be attached to the outer surface 102 of the temporary scaffolding, and as a result, the width w of the gap 11 between the lower frame 52 of the frame body 5 and the outer surface 102 of the temporary scaffolding may change. Even in such cases, in this embodiment, the gap shielding plate 6 is rotated downward and its tip is brought into contact with the outer surface 102 of the temporary scaffolding, so the gap 11 can be reliably sealed.

[0022] Next, other embodiments of the present invention will be described with reference to Figures 6 to 8. Note that components identical to those in the previously described embodiments are denoted by the same reference numerals and their descriptions are omitted. Figures 6(a) and 6(b) are front and cross-sectional views of the lower frame 521, respectively, and (c) is a front view of the gap shielding plate 61. Figure 7(a) is a perspective view of the connecting member 71 used in the gap shielding device shown in Figures 6(a) to 6(c), and (b) is a cross-sectional view thereof.

[0023] As shown in Figures 6(a) and (b), the lower frame 521 has a groove-shaped form, and multiple (four in this embodiment) through holes 12 are formed at appropriate intervals on one side surface 521a. On the other hand, the gap shielding plate 61 has holes 13 for rivet fastening formed at the upper part, corresponding to the through holes 12. A retaining member 9 is provided in the center of the gap shielding plate 61.

[0024] The connecting member 71 shown in Figures 7(a) and 7(b) is for connecting the gap shielding plate 61 to the lower frame 521. The connecting member 71 has a roughly T-shape consisting of a horizontal piece 71a and a vertical piece 71b perpendicular to the horizontal piece 71a. The horizontal piece 71a and the vertical piece 71b are integrally formed. As the connecting member 71, metal plates such as aluminum plates and steel plates, or hard materials such as hard synthetic resin plates can be used. Furthermore, the vertical piece 71b of the connecting member 71 may be a straight line parallel to the horizontal piece 71a, but it is preferable that it is bent relative to the horizontal piece 71a. The bending angle θ is preferably 90° or more and less than 180°, and preferably 100° or more and 150° or less.

[0025] To connect the gap shielding plate 61 to the lower frame 521 using the connecting member 71, first insert the vertical piece 71b through the through hole 12 from the inside of the lower frame 521, and attach the lower end of the vertical piece 71b to the gap shielding plate 61. To do this, align the hole 13' formed in the lower end of the vertical piece 71b with the hole 13 provided in the gap shielding plate 61, and insert the rivet 21 (see Figure 8) through these holes 13 and 13' to fix them together. In this state, the horizontal piece 71a will engage with the edge of the through hole 12 in the lower frame 521, thereby preventing the gap shielding plate 61 from falling off the lower frame 521, and allowing the gap shielding plate 61 to rotate vertically relative to the lower frame 521.

[0026] Figure 8(a) is a cross-sectional view showing the stored state of the gap shielding plate 61, and Figure 8(b) is a cross-sectional view showing an example of its use state. The gap shielding plate 61 can be rotated downward from the stored state shown in Figure 8(a) as indicated by the arrow. By rotating the gap shielding plate 61 until its tip contacts the outer surface 102 of the temporary scaffolding (see Figure 5), the gap between the outer surface 102 of the temporary scaffolding and the lower frame 521 can be sealed, thereby increasing safety. The rotatable range of the gap shielding plate 61 is determined by the bending angle θ of the connecting member 71. For example, if the bending angle θ is 90°, it can rotate within a range of 0° to 90° relative to the side surface 521a of the lower frame 521. The rest of the details are the same as in the previously described embodiment, so a detailed explanation will be omitted.

[0027] Next, yet another embodiment of the present invention will be described with reference to Figures 9-10. Note that components identical to those in the previously described embodiments are denoted by the same reference numerals and their descriptions are omitted. Figures 9(a) and (b) are front and cross-sectional views of the lower frame 522, respectively, and (c) is a front view of the gap shielding plate 62. Figure 10(a) is an exploded view of the connecting member 72 used in the gap shielding device shown in Figures 9(a) to (c), and (b) is a plan view showing its assembled state.

[0028] As shown in Figures 9(a) and (b), the lower frame 521 has a groove-shaped form, and multiple (four in this embodiment) through holes 121 are formed at appropriate intervals on one side surface 521a. On the other hand, the gap shielding plate 61 has holes 131 for riveting formed laterally at the upper part, corresponding to the through holes 12. In addition, a retaining member 9 similar to the above is provided in the center of the gap shielding plate 62.

[0029] The connecting member 72 shown in Figures 10(a) and (b) connects the gap shielding plate 61 to the lower frame 521 and has a roughly T-shape, connecting a horizontal piece 72a and a vertical piece 72b perpendicular to the horizontal piece 72a. The horizontal piece 72a is made of a hard material such as a metal plate such as an aluminum plate or steel plate, or a hard synthetic resin plate. The vertical piece 72b is made of a flexible material that can be bent. As the flexible material, for example, leather, cloth, rubber, synthetic resin, or composite sheet material made by laminating two or more of these materials can be used. The connection between the horizontal piece 72a and the vertical piece 72b is not particularly limited, but in this embodiment, the holes 131', 131' provided in the horizontal piece 72a and the vertical piece 72b are aligned, and rivets (not shown) are inserted through the holes 131', 131' to connect them integrally (see Figure 8(b)). The other holes 131 provided in the vertical piece 72b are aligned with the holes 131 provided in the gap shielding plate 61, and rivets (not shown) are inserted through these holes 131 to connect them together.

[0030] In the morning glory apparatus of this embodiment, configured in this manner, the vertical piece 72b of the connecting member 72, which is assembled in a roughly T-shape, is inserted through the through hole 121 from the inside of the lower frame 522, and the horizontal piece 72a is locked to the edge of the through hole 121, similar to the embodiment described above. Next, the other holes 131 provided in the vertical piece 72b are aligned with the holes 131 provided in the gap shielding plate 61, and rivets are inserted to connect them together.

[0031] The gap shielding device in this embodiment incorporates elements from the two embodiments described above. Specifically, the horizontal piece 72a engages with the edge of the through hole 121 in the lower frame 522, preventing the gap shielding plate 62 from falling out of the lower frame 522, and making installation easy. Incidentally, the opening width of the through hole 121 in the lower frame 522 only needs to be large enough for the vertical piece 72b to pass through, and therefore is the same as or slightly larger than the thickness of the vertical piece 72b, and is formed to be smaller than the through hole 12 in the embodiments described above. Furthermore, since the vertical piece 72b is made of a flexible, bendable soft material, the gap shielding plate 62 can be freely rotated in the vertical direction, and regardless of the size of the gap 11 between the outer surface of the temporary scaffolding and the lower frame 522, the gap 11 between the outer surface of the temporary scaffolding and the lower frame 522 can be reliably sealed. The rest of the details are the same as in the previously described embodiment, so a detailed explanation will be omitted.

[0032] Next, another embodiment of the present invention will be described with reference to Figures 11 to 14. Note that components identical to those in the previously described embodiments are denoted by the same reference numerals and their descriptions are omitted. Figure 11 is a side view showing the stored state of the gap shielding plate 63 in this embodiment. Figure 12 shows the connecting member 73 that connects the gap shielding plate 63 and the lower frame 523 shown in Figure 11, where (a) is a side view of the connecting member 73, (b) is a plan view, and (c) is an exploded perspective view of the end.

[0033] As shown in Figure 11, the gap shielding plate 63 is held in a position facing the outer surface of the lower frame 523 when stored, and the retaining material 9 used in the above embodiment is not used, but may be used if necessary. The reason why the retaining material 9 is not used is that the connecting material 73 itself has the function of holding the gap shielding plate 63 in the stored state, etc.

[0034] The connecting member 73 comprises a first support portion 21 attached to the lower side of the lower frame 523 when the gap shielding plate 63 is facing the side of the lower frame 523, a second support portion 22 attached to the surface of the gap shielding plate 63 at a position spaced above the side 523a of the lower frame 523 from the first support portion 21, and a link portion 23 whose ends are pivotally supported by the first support portion 21 and the second support portion 22, respectively. As shown in Figure 12(b), the first support portion 21 and the second support portion 22 have holes 132 formed therein for inserting fasteners such as rivets. One end of the link portion 23 is rotatably connected to the first support portion 21 by a pin 24, as shown in Figure 12(c). The other end of the link portion 23 is similarly rotatably connected to the first support portion 21. The connecting material 73 is made of, for example, an aluminum plate, a steel plate, or the like.

[0035] Next, the operation of deploying the gap shielding plate 63 from the stored state shown in Figure 11 will be explained based on Figures 13(a) and (b). As shown in Figure 13(a), when the gap shielding plate 63 in the stored state is rotated downward using the pivot axis of the first support part 21 as a fulcrum, the gap shielding plate 63 rotates further downward using the pivot axis of the second support part 22 as a fulcrum. As a result, the gap shielding plate 63 can be unfolded downward from the side surface 523a of the lower frame 523, as shown in Figure 13(b). During this unfolding process, the gap shielding plate 63 comes into contact with the outer surface of the temporary scaffolding, thereby sealing the gap that has formed between the lower frame 523 and the outer surface of the temporary scaffolding. To store the gap shielding plate 63, simply rotate it upwards, the opposite of the above. In this embodiment, a retaining material 9 is not required to hold the gap shielding plate 63 in the stored state as in the above embodiment, making it easier to handle.

[0036] Another example of the connecting material in this embodiment is shown in Figure 14. Figure 14(a) is a partial side view of the gap shielding plate 63 in its stored state, Figure 14(b) is a perspective view of the connecting material 74', and Figure 14(c) is a cross-sectional view along line AA. The connecting member 74' includes a first support portion 21' attached to the lower side of the lower frame 523 when the gap shielding plate 63 is facing the side of the lower frame 523, a second support portion 22' attached to the surface of the gap shielding plate 63 at a position spaced above the side surface 523a of the lower frame 523 from the first support portion 21', and a link portion 23' at both ends that are pivotally supported by the first support portion 21' and the second support portion 22', respectively. As shown in Figures 14(b) and (c), the first support portion 21' and the second support portion 22' have holes 132' formed in them for inserting fasteners such as rivets.

[0037] As shown in Figures 14(b) and (c), the first support portion 21' and the second support portion 22' each include a pair of L-shaped members, and can be manufactured by facing the two L-shaped members via a link portion 23' and joining the two L-shaped members with a pin 25. In this way, the first support portion 21' and the second support portion 22' rotatably hold the link portion 23'. Such a connecting member 74' can be used in the same manner as the connecting member 74 described above, and has the advantage of being easy to handle without the need for a retaining member 9.

[0038] Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications and improvements are possible within the scope of the present invention. For example, in the above embodiments, a sheet material 10 was used as a surface material attached to the frame, but instead of the sheet material 10, a panel material made of fiber-reinforced plastic or the like may be used. A morning glory apparatus using such a panel material is described, for example, in Japanese Utility Model Publication No. 7-42843. [Explanation of Symbols]
