DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] (Embodiment) Hereinafter, the morning glory device of the embodiment will be described with reference to the drawings. Fig. 1 is a schematic perspective view of the morning glory device 2 of the present embodiment. The morning glory device 2 shown in Fig. 1 is installed on a temporary scaffold to catch fallen materials, tools, and the like at the construction or repair work site of a mid- to high-rise building such as a building or condominium.

[0009] As shown in FIG. 1, the morning glory device 2 includes a panel unit 4, an outer frame 6, diagonal members 8A and 8B, and hanging members 10A and 10B.

[0010] The panel unit 4 is a main body of the morning glory device 2 that has a function of catching falling objects. As shown in Fig. 1, the panel unit 4 has a roughly flat plate shape and is installed at an angle. The inclination angle α of the panel unit 4 (the inclination angle with respect to the vertical single pipes 18A, 18B) may be adjustable in multiple stages.

[0011] The outer frame 6 is a member that surrounds the periphery of the panel unit 4. The outer frame 6 includes an upper frame 12, a lower frame 14, and a pair of unit rigid frames 16A and 16B. The upper frame 12 is attached to the upper edge of the panel unit 4, the lower frame 14 is attached to the lower edge of the panel unit 4, and the unit rigid frames 16A and 16B are attached to the left and right edges of the panel unit 4, respectively.

[0012] The upper frame 12, the lower frame 14 and the unit stiffeners 16A and 16B are all made of "aluminum profiles" made by extrusion molding using aluminum or an aluminum alloy as the raw material.

[0013] The diagonal members 8A, 8B are a pair of members for supporting the panel unit 4 from below. One end of the diagonal members 8A, 8B is fixed to the vertical single pipes 18A, 18B, and the other end is fixed to the unit rigid frames 16A, 16B, respectively. The hanging members 10A, 10B are a pair of members for suspending the panel unit 4. One end of the hanging members 10A, 10B is fixed to the vertical single pipes 18A, 18B, and the other end is fixed to the upper frame 12, respectively. The other ends of the hanging members 10A, 10B may be fixed to the unit rigid frames 16A, 16B instead of the upper frame 12.

[0014] Next, the panel unit 4 and the outer frame 6 are shown in Figures 2 and 3. Figure 2 is a schematic diagram showing the front side of the panel unit 4 and the outer frame 6, and Figure 3 is a schematic diagram showing the back side of the panel unit 4 and the outer frame 6. In Figures 2 and 3, (a) shows an overall view, and (b) shows a partially enlarged perspective view.

[0015] The surface (first surface) 20 of the panel unit 4 shown in Fig. 2 is a surface for receiving a falling object, and is arranged to face upward in the morning glory device 2. The surface 20 of the panel unit 4 has a crimped wire mesh 22. The crimped wire mesh 22 is a net-like member having elasticity, and has an energy absorbing function when a falling object hits it. The dimensions of the crimped wire mesh 22 are, for example, a wire diameter of 1.6 mm, and the spacing between the meshes is 12 mm.

[0016] 3 is the surface opposite to the front surface 20, and is disposed so as to face downward in the morning glory device 2. The back surface 24 of the panel unit 4, together with the outer frame 6, constitutes the exterior of the morning glory device 2. In this embodiment, the back surface 24 is formed of an aluminum shaped material 26, which extends parallel to the width direction X of the panel unit 4.

[0017] By constructing the rear surface 24 and the outer frame 6 of the panel unit 4 from aluminum shaped materials, the appearance of the morning glory device 2 can be unified with the aluminum shaped materials, improving the design, and further reducing the weight.

[0018] The aluminum profile 26 of this embodiment is configured in a so-called "corrugated" shape. The aluminum profile 26 has a wave-shaped shape in which the position in the thickness direction Y of the panel unit 4 changes continuously along the vertical direction Z. By using the corrugated aluminum profile 26, the strength can be improved, and even if the panel unit 4 is divided into multiple panels in the vertical direction Z as shown in FIG. 3(a), the seams can be made visually less visible, and the panel unit 4 can be made to look seamless. This improves the design of the morning glory device 2.

[0019] 4 and 5 are schematic diagrams showing a plurality of panels 28 that constitute the panel unit 4. Fig. 4 shows the front side of the panel unit 4, and Fig. 5 shows the back side of the panel unit 4.

[0020] As shown in Figures 4 and 5, the panel unit 4 is constructed by connecting a plurality of panels 28 in a row in the vertical direction Z. In this embodiment, one panel unit 4 is constructed by four panels 28. With the plurality of panels 28 connected, the panel unit 4 is surrounded by the outer frame 6 (Figures 2 and 3) described above, thereby constructing the panel unit 4 shown in Figures 1 to 3. A specific assembly method will be described later.

[0021] One panel 28 constituting the panel unit 4 will be described with reference to Figures 6 and 7. Figure 6 is a schematic diagram showing the front side of panel 28, and Figure 7 is a schematic diagram showing the back side of panel 28.

[0022] 6 and 7, in addition to the clamp wire mesh 22 on the front side and the aluminum profile 26 on the back side, the panel 28 has a handle 30 and panel rigid frames 32A and 32B. The handle 30 is a part that allows an operator to hold the panel 28, and the panel rigid frames 32A and 32B are a pair of members that form the left and right frames of the panel 28.

[0023] As shown by the dashed lines in FIGS. 6 and 7, the panel 28 is further divided into a plurality of members along the vertical direction Z.

[0024] Fig. 8 is a vertical cross-sectional view showing a plurality of types of members that constitute the panel 28. Fig. 9 is a vertical cross-sectional view showing the state in which the panel 28 is constituted by combining the members shown in Fig. 8.

[0025] 8, the components that make up the panel 28 are an upper member 34, a middle member 35, and a lower member 36. The upper member 34 (a) is a component that makes up the upper part of the panel 28, the middle member 35 (b) is a component that makes up the central part of the panel 28, and the lower member 36 (c) is a component that makes up the lower part of the panel 28.

[0026] 6 and 7 is formed by connecting the upper member 34, the middle member 35 and the lower member 36 in the vertical direction Z. The upper member 34, the middle member 35 and the lower member 36 are all formed from aluminum moldings.

[0027] The upper member 34 in (a) has a corrugated plate portion 38, an upper connecting portion 40, a lower connecting portion 42, a horizontal connecting portion 44, a net receiving portion 46, and a net supporting portion 48.

[0028] The corrugated plate portion 38 is a corrugated plate-like portion and extends in the vertical direction Z. The upper connecting portion 40 is a portion having a connecting shape provided at the top, and the lower connecting portion 42 is a portion having a connecting shape provided at the bottom. The upper connecting portion 40 has a shape that can be connected to the lower connecting portion 64 of the lower member 36 described later, and the lower connecting portion 42 has a shape that can be connected to the upper connecting portion 52 of the middle member 35. The handle 30 is provided in the area surrounded by the upper connecting portion 40. The horizontal connecting portion 44 is a portion for connecting and fixing the upper member 34 to the above-mentioned vertical panel frames 32A and 32B. The horizontal connecting portion 44 forms a recess for inserting a screw 72 (FIG. 9) described later. The net housing portion 46 is a portion for housing the upper end of the crimped wire mesh 22 (not shown). The net support portion 48 is a portion for supporting the crimped wire mesh 22 whose upper end is housed in the net housing portion 46. The net support portion 48 is a protrusion extending from the back side of the corrugated sheet portion 38 toward the crimped wire mesh 22 .

[0029] Of the upper member 34 having the above-mentioned configuration, the portion excluding the handle 30 is made of an integral aluminum shaped material. Specifically, the corrugated plate portion 38, the upper connecting portion 40, the lower connecting portion 42, the horizontal connecting portion 44, the net housing portion 46, and the net support portion 48 are made of an integral aluminum shaped material. However, without being limited to this case, a portion of the upper member 34 may be made of a separate aluminum shaped material and attached by welding or the like.

[0030] The central member 35 in (b) has a corrugated plate portion 50, an upper connecting portion 52, a lower connecting portion 54, a horizontal connecting portion 56, and a net support portion 58.

[0031] The corrugated plate portion 50 is a corrugated plate-like portion and extends in the vertical direction Z. The upper connecting portion 52 is a portion having a connecting shape provided at the top, and the lower connecting portion 54 is a portion having a connecting shape provided at the bottom. The upper connecting portion 52 has a shape that can be connected to the lower connecting portion 42 of the upper member 34 described above, and the lower connecting portion 54 has a shape that can be connected to the upper connecting portion 62 of the lower member 36 described later. The horizontal connecting portion 56 is a portion for connecting and fixing the middle member 35 to the panel vertical frames 32A and 32B described above, and forms a recess for inserting the screw 74 described later. The net support portion 58 is a protrusion for supporting the crimped wire mesh 22, and extends from the back side of the corrugated plate portion 50 toward the crimped wire mesh 22.

[0032] The central member 35 having the above-mentioned configuration is entirely made of an integral aluminum shaped material. Specifically, the corrugated plate portion 50, the upper connecting portion 52, the lower connecting portion 54, the horizontal connecting portion 56 and the net support portion 58 are made of an integral aluminum shaped material. However, the present invention is not limited to this case, and a part of the central member 35 may be made of a separate aluminum shaped material and attached by welding or the like.

[0033] The lower member 36 in (c) has a corrugated plate portion 60, an upper connecting portion 62, a lower connecting portion 64, a horizontal connecting portion 66, a net receiving portion 68, and a net supporting portion 70.

[0034] The corrugated plate portion 60 is a corrugated plate-like portion and extends in the vertical direction Z. The upper connecting portion 62 is a portion having a connecting shape provided at the top, and the lower connecting portion 64 is a portion having a connecting shape provided at the bottom. The upper connecting portion 62 has a shape that can be connected to the lower connecting portion 54 of the middle member 35 described above, and the lower connecting portion 64 has a shape that can be connected to the upper connecting portion 40 of the upper member 35. The horizontal connecting portion 66 is a portion for connecting and fixing the lower member 36 to the vertical panel frames 32A and 32B, and forms a recess for inserting a screw 76 described later. The net housing portion 68 is a portion for housing the lower end of the crimped wire mesh 22 (not shown). The net support portion 70 is a protrusion for supporting the crimped wire mesh 22 whose lower end is housed in the net housing portion 68.

[0035] The lower member 36 having the above-mentioned configuration is entirely made of an integral aluminum shaped material. Specifically, the corrugated plate portion 60, the upper connecting portion 62, the lower connecting portion 64, the horizontal connecting portion 66, the net housing portion 68 and the net support portion 70 are made of an integral aluminum shaped material. However, the present invention is not limited to this case, and a part of the lower member 36 may be made of a separate aluminum shaped material and attached by welding or the like.

[0036] When connecting the upper member 34 and the middle member 35, the lower connecting portion 42 of the upper member 34 can be inserted in the width direction X toward the internal space of the upper connecting portion 52 of the middle member 35. Similarly, when connecting the middle member 35 and the lower member 36, the lower connecting portion 54 of the middle member 35 can be inserted in the width direction X toward the internal space of the upper connecting portion 62 of the lower member 36. The upper member 34, the middle member 35, and the lower member 36 are all made of aluminum shaped materials that extend uniformly in the width direction X, and therefore can be easily inserted and connected.

[0037] 8, the lower connecting portion 42 of the upper member 34 and the lower connecting portion 54 of the middle member 35 have the same cross-sectional shape. Similarly, the upper connecting portion 52 of the middle member 35 and the upper connecting portion 62 of the lower member 36 have the same cross-sectional shape. Since the upper connecting portion 52 and the lower connecting portion 54 of the middle member 35 have a shape that allows them to be connected to each other, it is possible to connect the middle members 35 to each other. As a result, when connecting the middle members 35 between the upper member 34 and the lower member 36, any number of middle members 35 can be connected to each other and arranged, and the length of the vertical direction Z of the panel 28 can be changed.

[0038] As shown in FIG. 9, in the panel 28 of this embodiment, two middle members 35A and 35B are connected between the upper member 34 and the lower member 36. The upper middle member 35A is connected to the upper member 34, and the lower middle member 35B is connected to the lower member 36. The upper end of the crimped wire netting 22 is disposed in the net receiving portion 46 of the upper member 34, and the lower end of the crimped wire netting 22 is disposed in the net receiving portion 68 of the lower member 36. The crimped wire netting 22 constitutes the surface 20 of the panel 28 while being supported by a plurality of net supporting portions 48, 58, and 70. Screws 72, 74, and 76 are inserted into the horizontal connecting portions 44, 56, and 66, respectively, and are fixed to the panel rigid frames 32A and 32B shown in FIG. 6, FIG. 7, etc.

[0039] 9, the corrugated sheet portions 38, 50, 60 are continuously aligned at the connection points that connect the upper member 34, the middle member 35, and the lower member 36. This makes it difficult to visually recognize the seams between the corrugated sheet portions 38, 50, 60, and allows the panel 28 to appear seamless.

[0040] According to the panel 28 configured as above, when the crimp net 22 receives a falling object, the impact of the fall is transmitted to the upper member 34, the middle member 35, and the lower member 36 via the net support parts 48, 58, 70, etc. Even if the falling object hits a specific point on the crimp net 22, the impact is transmitted to multiple members via the connecting points, so the impact can be dispersed throughout the panel 28. This allows for a high energy absorption function.

[0041] When connecting the panels 28 shown in Fig. 9 in the vertical direction Z, the upper connecting portion 40 of the upper member 34 and the lower connecting portion 64 of the lower member 36 can be connected to each other. Fig. 10 shows the state in which the upper connecting portion 40 of the upper member 34 and the lower connecting portion 64 of the lower member 36 are connected.

[0042] 10, the upper end 78 of the upper connecting part 40 and the lower end 80 of the lower connecting part 64 have a concave-convex shape that fits together. This direct fit using the concave-convex shape allows the upper connecting part 40 of the upper member 34 to be easily connected by simply placing the lower connecting part 64 of the lower member 36 on the upper connecting part 40 of the upper member 34, and also makes it easier to transmit the impact of a falling object.

[0043] As shown in FIG. 10, the handle 30 is disposed in the area surrounded by the upper connecting portion 40 and the lower connecting portion 64, and is covered so that the handle 30 cannot be seen from the outside.

[0044] Returning to Fig. 9, the crimped wire mesh 22 is supported by a plurality of net support parts 48, 58, 70 and fixed at the fixed part A. The fixed part A will be described with reference to Figs. 11 and 12.

[0045] Fig. 11 is a vertical cross-sectional view showing the fixed portion A, and Fig. 12 is an exploded perspective view of the fixed portion A. As shown in Figs. 11 and 12, the fixed portion A is provided with a pressing member 82 and a fixing bolt 84.

[0046] The pressing member 82 is a member for pressing the crimped wire mesh 22. The pressing member 82 has a through hole 86 formed in the center, and has pressing parts 88A and 88B with a U-shaped cross section on both sides of the through hole 86.

[0047] The pressing parts 88A, 88B are pressed in the pressing direction B so as to accommodate the two vertical lines 90A, 90B of the crimped wire mesh 22. The pressing parts 88A, 88B are pressed against the side surface 92 of the upper connecting part 52 of the inner member 35 while accommodating the vertical lines 90A, 90B of the crimped wire mesh 22. In this state, the fixing bolt 84 is inserted into the through hole 86 of the pressing part 82, and further inserted into the through hole 94 of the side surface 92 and screwed together.

[0048] According to the above configuration, the crimp net 22 can be fixed by the fixing parts A to prevent it from falling off. In the example shown in Fig. 9, the fixing parts A are provided at two locations, one above the other, on one panel 28, but similar fixing parts A may also be provided at the connection between the inner members 35A and 35B. Furthermore, the fixing parts A may be provided at multiple locations spaced apart in the width direction X of the panel 28. For example, the fixing parts A may be provided at a total of four locations on one panel 28, two locations spaced apart in the width direction X and two locations spaced apart in the vertical direction Z.

[0049] 6 and 7, the left and right panel frames 32A, 32B of the panel 28 are fixed to the aluminum material 26 via bolts 72, 74, 76 (FIG. 9). The panel frames 32A, 32B fixed to the aluminum material 26 are attached by sliding in the vertical direction Z relative to the unit frames 16A, 16B (FIG. 1) of the outer frame 6 described above.

[0050] 13 and 14 are schematic diagrams showing the panel frames 32A and 32B arranged inside the unit frames 16A and 16B as viewed from above.

[0051] 13, the unit frame 16A is provided with a pair of return portions 96A. The panel frame 32A is provided with a pair of protrusions 98A corresponding to the return portions 96A of the unit frame 16A.

[0052] When the panel frame 32A is inserted into the unit frame 16A in the vertical direction Z, the return portion 96A and the protrusion 98A are inserted in a state where they face each other. The return portion 96A and the protrusion 98A have shapes that are inclined in the same direction when viewed in the vertical direction Z, and act as a retainer for the panel frame 32A.

[0053] The panel frame 32A is further provided with a protrusion 100A in addition to the protrusion 98A. The protrusion 100A is a pair of protrusions protruding in the width direction X. The above-mentioned screws 72, 74, and 76 are disposed between the two protrusions 100A. Providing the protrusion 100A can suppress rattling and rotational deviation of the panel frame 32A when inserting the panel frame 32A into the unit frame 16A, improving the ease of insertion.

[0054] Both the unit rigid frame 16A and the vertical panel frame 32A are made of aluminum material that extends uniformly in the vertical direction Z. Therefore, the return portion 96A, the protruding portion 98A, and the protruding portion 100A also extend uniformly along the vertical direction Z.

[0055] As shown in Fig. 14, the unit frame 16B and the panel frame 32B have a structure symmetrical to the unit frame 16A and the panel frame 32A shown in Fig. 13. The unit frame 16B has a return portion 96B, and the panel frame 32B has protrusions 98B, 100B. The return portion 96B and the protrusions 98B, 100B have cross-sectional shapes symmetrical to the return portion 96A and the protrusions 98A, 100A shown in Fig. 13, and provide similar functions and effects.

[0056] Next, a method of assembling the panel unit 4 by inserting the panel frames 32A, 32B into the unit frames 16A, 16B in the Z direction will be described with reference to FIGS.

[0057] 15 and 16 are schematic diagrams for explaining a method of assembling the panel unit 4 using a plurality of panels 28 and the outer frame 6. FIG.

[0058] As shown in Fig. 15, the unit rigid frames 16A, 16B are fixed to the bottom frame 14 in advance with screws or the like, and the rigid frames 32A, 32B of the panel 28 are inserted into the unit rigid frames 16A, 16B in the vertical direction Z (arrows C, D). As described with reference to Figs. 13 and 14, the return portions 96A, 96B, the protrusions 98A, 98B, and the protrusions 100A, 100B are provided, so that the panel 28 can be inserted while preventing rattling or rotational deviation, facilitating the insertion and installation work.

[0059] In the example shown in Figure 15, two panels 28 have already been installed, a third panel 28 is in the process of being inserted (arrow D), and a fourth panel 28 is about to be inserted (arrow C). Once the third and fourth panels 28 have been inserted, the state shown in Figure 16 is obtained.

[0060] As shown in Fig. 16, once the insertion and installation of the four panels 28 is complete, the upper frame 12 is attached toward the upper end of the topmost panel 28 and the unit frames 16A, 16B (arrow E). The left and right ends of the upper frame 12 are fixed to the upper ends of the unit frames 16A, 16B with screws or the like to form an outer frame 6 that surrounds the four panels 28. The handle 30 of the topmost panel 28 is covered by the upper frame 12, and the panel unit 4 as shown in Figs. 1 to 3 is completed.

[0061] Thereafter, the completed panel unit 4 is attached to the diagonal members 8A, 8B and the hanging members 10A, 10B (FIG. 1) and placed in a predetermined position on the temporary scaffolding, whereby the morning glory device 2 is installed.

[0062] According to the above-mentioned morning glory device 2, by providing the crimp net 22 on the surface 20 of the panel unit 4, it is possible to absorb the impact when a falling object is received, while preventing even sharp falling objects from penetrating and falling. This allows high safety to be realized. Furthermore, by providing the aluminum shaped material 26 on the back surface 24 of the panel unit 4, it is possible to present the appearance of an aluminum shaped material integrated with the outer frame 6, and to improve the design. Furthermore, by dividing the aluminum shaped material 26 in the vertical direction Z and using a corrugated sheet, it is possible to make the joints between the aluminum shaped materials less visible, making it look seamless, while making it easier to disperse the impact when a falling object is received over the entire panel unit 4. This allows high design and safety to be realized, and a high-quality morning glory device 2 to be provided.

[0063] As described above, the morning glory device 2 of this embodiment is a morning glory device that is installed on temporary scaffolding, and comprises a panel unit 4 arranged at an angle and an outer frame 6 that surrounds the periphery of the panel unit 4, and the panel unit 4 has a front surface 20 (first surface) that receives falling objects and a back surface 24 (second surface) opposite the front surface 20, and the back surface 24 and the outer frame 6 are constructed from aluminum moldings.

[0064] According to such a configuration, the appearance of the Morning Glory device 2 can be unified with aluminum moldings to enhance the design, and the weight can be reduced, thereby improving the quality of the Morning Glory device 2.

[0065] Moreover, in the Morning Glory device 2 of this embodiment, the back surface 24 is made of a corrugated aluminum material 26. With such a configuration, the strength and design of the Morning Glory device 2 can be improved.

[0066] Moreover, in the Morning Glory device 2 of this embodiment, the back surface 24 is formed by combining a plurality of corrugated aluminum shaped materials 26. With such a configuration, the corrugated shape makes it difficult to visually recognize the seams between the aluminum shaped materials 26, and the design can be improved even when a plurality of aluminum shaped materials 26 are combined.

[0067] Moreover, in the morning glory device 2 of this embodiment, adjacent corrugated aluminum shapes 26 are directly joined to each other (FIG. 10). With this configuration, the joints between the corrugated aluminum shapes 26 can be made less visible, improving the design.

[0068] Moreover, in the morning glory device 2 of this embodiment, the surface 20 of the panel unit 4 has a crimped wire mesh 22 as a net. With this configuration, by using a net for the surface 20 of the panel unit 4, it is possible to absorb the impact energy when a falling object hits. Furthermore, by using the crimped wire mesh 22, it is possible to prevent falling or penetration when a sharp falling object is received, thereby achieving a high level of safety.

[0069] Moreover, in the morning glory device 2 of this embodiment, a net support part 48 is provided inside the panel unit 4, and the net support part 48 protrudes in a direction from the back surface 24 toward the front surface 20 to support the crimped wire mesh 22. With this configuration, the crimped wire mesh 22 can be supported with a simple structure.

[0070] Furthermore, in the morning glory device 2 of this embodiment, the front surface 20 of the panel unit 4 has net housing parts 46, 68 that respectively house one end and the other end of the crimped wire mesh 22, and the net housing parts 46, 68 are configured integrally with the aluminum profile 26 that configures the back surface 24. With this configuration, the net housing parts 46, 68 can be formed with a simple structure, and manufacturing costs can be reduced.

[0071] Moreover, in the Morning Glory device 2 of this embodiment, a gap is provided between the front surface 20 and the back surface 24 (FIGS. 9, 13, and 14). With this configuration, when a falling object collides with the front surface 20, the impact received by the front surface 20 is easily transmitted to the entire Morning Glory device 2, including the back surface 24.

[0072] Moreover, in the morning glory device 2 of this embodiment, the panel unit 4 has a plurality of panels 28 arranged in a row, the outer frame 6 surrounds the periphery of the plurality of panels 28, and the back surface 24 of each panel 28 is formed of an aluminum shaped material 26. According to this configuration, by forming the panel unit 4 from a plurality of panels 28, the dimensions of the aluminum shaped material 26 of each panel 28 can be reduced, making it less susceptible to manufacturing constraints, while also making it easier to disperse the impact when a falling object is received.

[0073] Moreover, in the morning glory device 2 of this embodiment, the aluminum shaped material 26 constituting the back surface 24 of each panel 28 is formed by combining a plurality of corrugated aluminum shaped materials (upper member 34, middle member 35, lower member 36). With such a configuration, the dimensions of the aluminum shaped material 26 constituting each panel 28 can be reduced to reduce restrictions in manufacturing, while the corrugated shape makes it difficult to visually recognize the seams between the aluminum shaped materials 26, improving design.

[0074] The present invention is not limited to the above-described embodiment, and can be embodied in various other forms. For example, in the embodiment, the panel unit 4 is configured with four panels 28, but the present invention is not limited to this, and any number of panels 28 may be used. In the embodiment, the crimped wire mesh 22 is provided on the surface 20 of the panel unit 4, but any net-like material may be used.

[0075] Although the present invention has been fully described in connection with the preferred embodiment with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art. Such changes and modifications should be understood to be included within the scope of the present invention as defined by the appended claims, unless they deviate therefrom. Also, changes in the combination and order of the elements in the embodiments may be made without departing from the scope and spirit of the present invention. [Industrial Applicability]
