Description

[Technical Field]

[0001] The present invention relates to an eaves gutter hanger that is attached in a suspended and fixed state to a roof. [Background technology]

[0002] Conventional eaves gutter hangers of this type are configured so that the upper part of the hanging bolt is fixed to the peak of the folded-plate roof and the gutter support body is fixed to the lower part of the hanging bolt, and the eaves gutter can be hung and supported by the gutter support body (see, for example, Patent Document 1).

[0003] The eaves gutter hanger of Patent Document 1 prevents the hanging bolts from swaying due to loosening by inserting the hanging bolts into the roof and fastening them with nuts on the top and bottom to clamp the roof. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-37462 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there is a problem in that the suspension bolts swing when the suspended gutter or the gutter support body from which the gutter is suspended swings in the wind, causing the nuts to loosen, which in turn makes the suspension bolts more susceptible to swinging.Because the suspension bolts are attached in the vertical direction, even if the nuts do not loosen, it is difficult to completely prevent the lower parts of the suspension bolts from swinging back and forth and side to side.

[0006] The present invention was proposed in consideration of these circumstances, and its purpose is to provide an eaves gutter hanger and a reinforcing device used therewith that can suppress the shaking of the hanging bolts due to various factors. [Means for solving the problem]

[0007] In order to achieve the above object, the eaves gutter hanger of the present invention is an eaves gutter hanger comprising a gutter support body that suspends and supports an eaves gutter, a hanger bolt that is inserted into a roof and fixed by an upper nut arranged above the roof and a lower nut arranged below the roof, and a reinforcing member, wherein the hanger bolt comprises an upper threaded portion into which the upper nut and the lower nut are threadedly engaged, a lower threaded portion that screws and fixes the gutter support body, and a non-threaded portion arranged between the upper threaded portion and the lower threaded portion, and the upper end of the non-threaded portion serves as a stopper that prevents the lower nut from moving downwards. The reinforcing device comprises an upper plate portion having an upper insertion hole through which the hanging bolt is inserted, a lower plate portion having a lower insertion hole through which the hanging bolt is inserted, and a connecting portion connecting the upper plate portion and the lower plate portion, and the roof and the upper plate portion are sandwiched and fixed between the upper nut and the lower nut with the hanging bolt inserted into the upper insertion hole and the lower insertion hole so that the upper screw portion penetrates the roof when the upper plate portion is in close contact with the underside of the roof and so that the lower end of the upper screw portion is positioned between the upper plate portion and the lower plate portion. [Effects of the Invention]

[0008] Since the present invention has the above-described configuration, it is possible to suppress the swinging of the suspension bolt due to various factors. [Brief explanation of the drawings]

[Figure 8] FIG. 10 is a side view of an eaves gutter hanger according to a fourth embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. First, the basic configuration of the eaves gutter hangers 10, 10A, 10B, and 10C according to the embodiments of the present invention will be described.

[0011] The eaves gutter hangers 10, 10A, 10B, and 10C comprise a gutter support body 40 that suspends and supports the eaves gutter 50, a hanger bolt 20 that is inserted into the roof 1 and fixed by an upper nut 15 arranged above the roof 1 and a lower nut 18 arranged below the roof 1, and reinforcing members 30, 30A, 30B, and 30C.

[0012] The hanging bolt 20 has an upper threaded portion 21 onto which the upper nut 15 and the lower nut 18 are threaded, a lower threaded portion 22 that screws into the gutter support body 40, and a non-threaded portion 23 disposed between the upper threaded portion 21 and the lower threaded portion 22. The upper end 23a of the non-threaded portion 23 serves as a stopper that prevents the lower nut 18 from moving downward.

[0013] The reinforcing members 30, 30A, 30B, and 30C each include an upper plate portion 31 having an upper insertion hole 31a through which the hanging bolt 20 is inserted, a lower plate portion 32 having a lower insertion hole 32a through which the hanging bolt 20 is inserted, and a connecting portion 33 connecting the upper plate portion 31 and the lower plate portion 32.

[0014] With the upper plate portion 31 in close contact with the underside of the roof 1, the upper threaded portion 21 penetrates the roof 1, and the lower end 21a of the upper threaded portion 21 is positioned between the upper plate portion 31 and the lower plate portion 32, and with the suspension bolt 20 inserted through the upper through-hole 31a and the lower through-hole 32a, the roof 1 and the upper plate portion 31 are sandwiched and fixed between the upper nut 15 and the lower nut 18. In the multiple embodiments described below, the upper nut 15 is configured as a helical washer.

[0015] Each of the multiple eaves gutter hangers 10, 10A, 10B, and 10C described below is attached to the top surface 2a of the peak portion 2 of a roof 1 (folded plate roof) in which peak portions 2 and valley portions 3 are alternately connected, as shown in Figure 2(b), for example, and is hung down to suspend and support the eaves gutter 50.

[0016] Next, the eaves gutter hanger 10 according to the first embodiment will be described with reference to Figures 1 to 3. Figure 1 is a partially exploded front view of the eaves gutter hanger 10, Figure 2(a) is a perspective view of a reinforcing member 30 used in the eaves gutter hanger 10 of Figure 1, and Figure 2(b) is a front view of the installed state showing one mode of use of the eaves gutter hanger 10. Figure 3 is a side view of the same.

[0017] This eaves gutter hanger 10 comprises a hanging bolt 20, a washer (upper nut 15), a gasket 16, a lower nut 18, and a reinforcing element 30 (see Figure 1), and further comprises a gutter support body 40 which is fixed to the hanging bolt 20 with two clamping nuts 45, 46 (see Figure 3).

[0018] 1 is a front view of the eaves gutter hanger 1, but the eaves gutter hanger 10 may be attached so that its front faces the front of the eaves edge, or so that it faces the side of the eaves edge. Figures 2(b) and 3 show examples of how the eaves gutter hanger 10 is attached so that its front faces the side of the eaves edge.

[0019] That is, in the illustrated example of this embodiment, the eaves gutter hanger 10 is attached so that the longitudinal direction of the upper plate portion 31 of the reinforcement 30 is aligned with the formation direction of the peak portion 2 (top surface portion 2a) of the roof 1, i.e., the ridge direction (see Figures 2(b) and 6).

[0020] The hanging bolt 20 has an upper threaded portion 21 for screwing the roof 1 with an upper nut 15 and a lower nut 18, a lower threaded portion 22 for fixing the gutter support body 40 with two clamping nuts 45, 46, and a non-threaded portion 23 arranged between the upper threaded portion 21 and the lower threaded portion 22.

[0021] Here, the upper end 23 a of the non-threaded portion 23 acts as a stopper that prevents the lower nut 18 from moving downward beyond the lower end 21 a of the upper threaded portion 21 .

[0022] The reinforcing element 30 used in the eaves gutter hanger 10 is made by bending a strip of metal material. The reinforcing element 30 may also be made from a hard synthetic resin material.

[0023] As shown in Figures 1 and 2(a), the reinforcing element 30 comprises an upper plate portion 31, a lower plate portion 32 that is approximately parallel to the upper plate portion 31, and a connecting portion 33 consisting of a single leg piece 33a that connects one end of the longitudinal direction of the upper plate portion 31 and the lower plate portion 32, and is approximately U-shaped when viewed from the front.

[0024] The distance between the upper plate portion 31 and the lower plate portion 32 need only be large enough to accommodate the lower nut 18. Furthermore, since the reinforcing member 30 also reinforces the suspension bolt 20 as will be described later, it is desirable that the distance be such that the lower plate portion 32 is located approximately in the center of the entire length of the suspension bolt 20.

[0025] The reinforcing element 30 has an upper plate portion 31, a lower plate portion 32 and a connecting portion 33 whose width dimensions are approximately the same, the upper plate portion 31 being slightly longer than the lower plate portion 32, an upper insertion hole 31a being opened in the upper plate portion 31 at approximately the center in the longitudinal direction, and a lower insertion hole 32a being opened in the lower plate portion 32 at approximately the center in the longitudinal direction of the upper plate portion 31 (see Figure 2(a)).

[0026] To attach the hanging bolt 20 and the reinforcing element 30 to the roof, with the lower nut 18 threaded onto the lower end 21a of the upper threaded portion 21 of the hanging bolt 20, the upper plate portion 31 of the reinforcing element 30 is positioned so as to contact the back surface of the roof 1, the upper threaded portion 21 is inserted through the upper plate portion 31 and the roof 1, a gasket 16 is attached to the top of the upper threaded portion 21 that protrudes above the roof 1, and the upper nut 15 is threaded onto the roof so that the roof and the upper plate portion are sandwiched between the upper nut 15 and the lower nut 18. In this way, the hanging bolt 20 and the reinforcing element 30 are fixed to the roof 1.

[0027] In other words, if the lower nut 18 is placed on the lower end 21a of the upper threaded portion 21 of the hanging bolt 20, the upper end 23a of the non-threaded portion 23 acts as a stopper, so the lower nut 18 will not shift downward, and the upper plate portion 31 of the reinforcement 30, the roof 1, and the gasket 16 will be fixed without any gaps between the upper nut 15 and the upper side of the lower nut 18 screwed onto the upper threaded portion 21.

[0028] The boundary between the non-threaded portion 23 and the lower threaded portion 22 of the hanging bolt 20 is located below the lower plate portion 32 of the reinforcing element 30, including in other embodiments described below, but is not limited to this and may also be located between the upper plate portion 31 and the lower plate portion 32.

[0029] As shown in FIG. 3, the gutter support body 40 is fixed to the lower threaded portion 22 of the hanging bolt 20 with two clamping nuts 45 and 46.

[0030] The gutter support body 40 is made by processing a strip plate material and comprises a main body portion 41 for attaching the hanging bolt 20, a front ear hook portion 42, and a rear ear hook portion 43. The main body portion 41 is provided with an insertion hole (long hole) (not shown) through which the hanging bolt 20 is inserted. The front ear hook portion 42 and the rear ear hook portion 43 are each provided with spring pieces 42a, 43a that press the front ear 51 and rear ear 52 of the attached eaves gutter 50 from the inside to make it difficult to come off.

[0031] Since the roof 1 to which the installation is to be performed, as shown in Figure 3, is sloped, the hanging bolt 20 is bent at an appropriate position in the non-threaded portion 23 below the lower plate portion 32, and the lower threaded portion 22 is arranged vertically, so that the eaves gutter 50 is installed without tilting.

[0032] Next, an eaves gutter hanger 10A according to a second embodiment will be described with reference to Figures 4 and 5. Figure 4(a) is a partially omitted front view of the eaves gutter hanger 10A showing the state of attachment to the roof 1, Figure 4(b) is a plan view of the reinforcing member 30A, and Figure 4(c) is a cross-sectional view taken along line AA in Figure 1. Figure 5 is a front view of the attached state showing one mode of use of the eaves gutter hanger 10A.

[0033] The eaves gutter hanger 10A of the second embodiment comprises a hanging bolt 20, a washer (upper nut 15), a gasket 16, a lower nut 18, and a reinforcing element 30A (see Figure 4), and further comprises a gutter support body 40 fixed to the hanging bolt 20 with two clamping nuts 45, 46 (see Figure 5).

[0034] The hanging bolt 20 and the gutter support body 40 have the same configuration and shape as those in Figure 1, and detailed description thereof will be omitted. The positional relationship between the hanging bolt 20 and the reinforcing device 30A is also the same as that in Figure 1. In other words, when the eaves gutter hanger 10A is installed, the boundary between the upper threaded portion 21 and the non-threaded portion 23 is located between the upper plate portion 31 and the lower plate portion 32 of the reinforcing device 30A.

[0035] The reinforcing element 30A used in this embodiment has a hexagonal ring shape when viewed from the front, and includes an upper plate portion 31, a lower plate portion 32 that is substantially parallel to the upper plate portion 31, and a connecting portion 33 consisting of two leg pieces 33a that connect both ends of the longitudinal direction of the upper plate portion 31 and the lower plate portion 32. Each of the leg pieces 33a is bent midway in the vertical direction toward the lower plate portion 32 at an obtuse angle.

[0036] The reinforcing member 30A may be formed into a ring shape by bending a metal strip and welding it, for example. The spacing between the upper plate portion 31 and the lower plate portion 32 is the same as that in the first embodiment.

[0037] The reinforcing element 30A has an upper plate portion 31, a lower plate portion 32 and a connecting portion 33 whose width dimensions are approximately the same, the upper plate portion being slightly longer than the lower plate portion, an upper insertion hole 31a being opened in approximately the longitudinal center of the upper plate portion 31, and a lower insertion hole 32a being opened in approximately the longitudinal center of the upper plate portion 31 in the lower plate portion 32 (see Figures 4(b) and (c)).

[0038] The procedure for attaching the eaves gutter hanger 10A to the roof 1 is the same as that of the first embodiment. In the example of Fig. 4(a), the front of the reinforcement 30A is attached to the front of the eaves edge (see Fig. 4(a) and Fig. 6), but it may also be attached to the side of the eaves edge, as shown by the two-dot chain line in Fig. 5.

[0039] That is, in the illustrated example of this embodiment, the eaves gutter hanger 10A is attached so that the longitudinal direction of the upper plate portion 31 of the reinforcing element 30A is aligned with the width direction of the peak portion 2 (top surface portion 2a) (the longitudinal direction of the eaves gutter 50, a direction parallel to the eaves edge) (see Figures 2(b) and 6). In order to achieve this type of attachment, the longitudinal dimension of the upper plate portion 31 needs to be smaller than the width dimension of the peak portion 2 (top surface portion 2a), but it is desirable that it be longer than two-thirds of the width dimension of the peak portion 2 (top surface portion 2a).

[0040] The two types of eaves gutter hangers 10, 10A shown above are attached to multiple ridges 2 of the roof 1 as shown in Figure 6, and the eaves gutter 50 is suspended and supported by these eaves gutter hangers 10, 10A. Note that in Figure 6, the eaves gutter hanger 10 and reinforcing device 30 in Figure 1 are shown with dashed lines, and the eaves gutter hanger 10A and reinforcing device 30A in Figure 4 are shown with two-dot chain lines.

[0041] As shown in Figures 2(b) and 4(a), the eaves gutter hangers 10, 10A have the upper plate portions 31 of the reinforcing members 30, 30A abutting against the underside of the roof 1 and clamping and fixing them together, which can suppress swinging of the hanging bolts 20 after installation. In addition, the lower plate portions 32 of the reinforcing members 30, 30A are positioned in the middle of the hanging bolts 20, which can also reinforce the hanging bolts 20 themselves.

[0042] Furthermore, because there is no risk of the lower nut 18 of the eaves gutter hanger 10, 10A falling below the lower end 21a of the upper threaded portion 21, loosening of the eaves gutter hanger 10, 10A can be prevented unless loosening of the upper nut 15 occurs. Therefore, shaking due to loosening of the lower nut 18 can also be suppressed.

[0043] When attaching the eaves gutter hanger 10 to a sloped roof 1 as in the example of Figure 3, the eaves gutter 50 and the eaves gutter hanger 10 are prone to swaying in the direction of the ridge of the mountain, so in order to mitigate the swaying, it is desirable to arrange the reinforcement 30 so that the longitudinal direction of the upper plate portion 31 is aligned in the direction of the ridge as shown in Figure 3.

[0044] Furthermore, the two types of gutter hangers 10, 10A mentioned above can be installed in two different ways by changing the orientation of the reinforcing members 30, 30A, so the installation method appropriate for the site can be selected. Also, for example, the gutter hangers 10, 10A can be arranged so that the orientation of the reinforcing members 30, 30A alternates.

[0045] Furthermore, the reinforcing element 30 used in the first embodiment is easy to manufacture and can save materials because the connecting portion 33 is formed by one leg piece 33a and is not ring-shaped. The reinforcing element 30A used in the second embodiment is polygonal ring-shaped, so it is more difficult to manufacture than the first embodiment and may require more material, but the reinforcing element 30A itself can be made stronger.

[0046] Next, an eaves gutter hanger 10B according to a third embodiment will be described with reference to Fig. 7. Fig. 7(a) is a perspective view of a reinforcing element 30B used in the eaves gutter hanger 10B, and Fig. 7(b) is a side view showing the installation mode of the eaves gutter hanger 10B. The reinforcing element 30B used in this eaves gutter hanger 10B can be retrofitted to an already installed hanging bolt 20.

[0047] The eaves gutter hanger 10B of the third embodiment comprises a hanging bolt 20, a washer (upper nut 15), a gasket 16, a lower nut 18, and a reinforcing element 30B (see Figure 7), and further comprises a gutter support body 40 fixed to the hanging bolt 20 with two clamping nuts 45, 46 (see Figure 3).

[0048] The hanging bolt 20 and the gutter support body 40 have the same configuration and shape as those in Figure 1, and detailed description thereof will be omitted. The positional relationship between the hanging bolt 20 and the reinforcing element 30A is also the same as that in Figure 1. In other words, when the eaves gutter hanger 10B is installed, the boundary between the upper threaded portion 21 and the non-threaded portion 23 is located between the upper plate portion 31 and the lower plate portion 32 of the reinforcing element 30B.

[0049] The reinforcing member 30B is generally U-shaped like the reinforcing member 30 in Fig. 2(a), and as shown in Fig. 7(a), comprises an upper plate portion 31, a lower plate portion 32, and a connecting portion 33. The upper through-hole 31a of the upper plate portion 31 and the lower through-hole 32a of the lower plate portion 32 each have a bolt mounting opening 31c, 32c formed on one end face in the width direction of each plate portion.

[0050] The bolt mounting openings 31c, 32c of each insertion hole are widened outward (laterally), and the space between the entrance and exit sides of the mounting round holes 31b, 32b and the bolt mounting openings 31c, 32c is narrowed, making it easy to guide the mounting of the hanging bolt 20 and making it difficult for the hanging bolt 20 to come out once mounted.

[0051] As shown in Figure 7(b), this reinforcing element 30B can be attached to the previously attached and fixed suspension bolt 20. When attaching the reinforcing element 30A, the upper nut 15 and the packing 16 are shifted slightly upward to create an attachment gap S, as shown in the figure.

[0052] Next, an eaves gutter hanger 10C according to a fourth embodiment will be described with reference to the side view of Fig. 8. A reinforcing member 30C used in this eaves gutter hanger 10C is made up of a combination of two members.

[0053] The eaves gutter hanger 10C of the fourth embodiment comprises a hanging bolt 20, a washer (upper nut 15), a gasket 16, a lower nut 18, and a reinforcing element 30C (see Figure 8), and further comprises a gutter support body 40 fixed to the hanging bolt 20 with two clamping nuts 45, 46 (see Figure 3).

[0054] The hanging bolt 20 and the gutter support body 40 have the same configuration and shape as those in Figure 1, and detailed description thereof will be omitted. The positional relationship between the hanging bolt 20 and the reinforcing element 30A is also the same as that in Figure 1. In other words, when the eaves gutter hanger 10C is installed, the boundary between the upper threaded portion 21 and the non-threaded portion 23 is located between the upper plate portion 31 and the lower plate portion 32 of the reinforcing element 30C.

[0055] The reinforcing element 30C is formed by combining and fixing two U-shaped divided members 300 together to form a ring. Each divided member 300 has a bottom piece 301, a pair of upright pieces 302 standing on both ends of the bottom piece 301, and a pair of mounting pieces 303 extending outward from the tips of the upright pieces 302 and generally parallel to the bottom piece 301.

[0056] The reinforcing member 30C is formed by combining two divided members 300 with their mounting pieces 303 butted together and fixed together. The mounting pieces 303 may be fixed together by welding or with bolts, nuts, or the like.

[0057] A round hole is formed approximately in the longitudinal center of the bottom piece 301 of each of the two divided members 300. The bottom piece 301 of the upper divided member constitutes the upper plate 31, the bottom piece 301 of the lower divided member constitutes the lower plate 32, and the two upright pieces 302 connected to extend vertically constitute leg pieces 33a, and these two leg pieces 33a constitute the connecting portion 33.

[0058] By combining two separate members 300 in this manner to form the reinforcing element 30C, the reinforcing element 30C is formed with an upper plate portion 31 having an upper through-hole 31a, a lower plate portion 32 having a lower through-hole 32a, and a connecting portion 33 consisting of two leg pieces 33a.

[0059] This eaves gutter hanger 10C has a reinforcing element 30C made up of two components, making it easy to form a sturdy, annular (square ring-shaped) reinforcing element 30C. In particular, by adjusting the combination of the upper and lower divided components 300 in various ways, it is possible to form a reinforcing element 30C that matches the dimensions of the hanging bolt. For example, it is possible to form a reinforcing element 30C that corresponds to approximately the entire length of the hanging bolt 20.

[0060] Since the roof 1 to which the attachment is to be made as shown in FIG. 8 has a slope, the load on the hanging bolt 20 may be reduced by bending the hanging bolt 20 as in the case of FIG. 3, or the hanging bolt may be reinforced by attaching a reinforcing element 30C corresponding to approximately the entire length of the hanging bolt 20.

[0061] It goes without saying that the eaves gutter hangers 10B and 10C according to the third and fourth embodiments described above have the same effects as the eaves gutter hangers 10 and 10A according to the first and second embodiments.

[0062] It goes without saying that the eaves gutter hangers 10, 10A, 10B, and 10C are not limited to the four examples mentioned above, and can be modified as appropriate in terms of shape and design. In particular, the reinforcing members 30, 30A, 30B, and 30C are not limited to U-shaped or polygonal ring-shaped ones, and may be of various other shapes. [Explanation of symbols]
