Description

[Technical Field]

[0001] The present invention relates to a glazing mechanism that is installed below the exterior wall of a building. [Background technology]

[0002] A trim mechanism installed below the exterior wall of a building may be configured, for example, by connecting multiple fragmentary members in the width direction of the exterior wall. Each of the multiple fragmentary members may have an inclined portion and a bottom portion, as shown in Patent Document 1. The inclined portion is a portion that faces the lower end of the exterior wall and descends toward the exterior, and the bottom portion is a portion that is located below the inclined portion and extends toward the exterior.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-031116 Summary of the Invention [Problem to be solved by the invention]

[0004] In a barrier mechanism made up of multiple fragments, each of which has an inclined portion and a bottom, a gap is formed between two adjacent fragments, particularly between the inclined portions of the two fragments. Liquid water, such as rainwater, may enter the space (hereinafter also referred to as the hollow portion) between the inclined portion and the bottom through this gap and remain inside the hollow portion. Liquid water in the hollow portion may flow out of the hollow portion after rain, for example, and potentially hit an object or person below the barrier mechanism.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to provide a barrier mechanism that can prevent water from entering the hollow portion. [Means for solving the problem]

[0006] The above problem is solved by the trim mechanism of the present invention, which is arranged below the exterior wall of a building and is composed of a number of fragmentary members lined up in the width direction of the exterior wall, each of the fragmentary members having an inclined portion facing the lower end of the exterior wall and descending toward the outdoors, and a bottom portion located below the inclined portion and extending toward the outdoors, and a gap sealing portion attached to the underside of the inclined portion that seals the gap between the inclined portions of two adjacent fragmentary members. The parting mechanism configured as described above can prevent water from entering the hollow portion because the gap between the inclined portions of two adjacent fragment members (hereinafter referred to as the gap between the inclined portions) is blocked by the gap blocking portion.

[0007] In the above-described parting mechanism, the gap closing portion may be made of a plate material, which can effectively close the gap between the inclined portions.

[0008] In the above-described parting mechanism, it is more preferable that the gap closing portion is made of a plate material whose surface is covered with a waterproof material, in which case the gap between the inclined portions can be closed more effectively. In the above-described configuration, it is more preferable that the water-stopping material is a foam-type water-stopping material, which can more effectively seal the gaps between the inclined portions.

[0009] In addition, in the above-mentioned partition mechanism, a sealant may be filled between the inclined portion and the lower end of the exterior wall, which can prevent liquid water such as rainwater from seeping in between the inclined portion and the lower end of the exterior wall.

[0010] In the above-described parting mechanism, each of the plurality of fragmentary members may further include a hanging portion continuous with the outdoor end of the inclined portion. In such a configuration, the hollow portion is partitioned by the hanging portion, so that water (liquid water) in the hollow portion tends to remain within the hollow portion. In such a situation, the effect of the present invention, which prevents water from entering the hollow portion, is more pronounced.

[0011] In the above-described parting mechanism, it is preferable that the gap closing portion closes the gap from the indoor end to the outdoor end of the gap. With this configuration, the gap between the inclined portions can be sufficiently closed, and water infiltration into the hollow portion can be more reliably prevented.

[0012] In the above-described partitioning mechanism, each of the plurality of fragmentary members may further include a rising portion rising from the upper surface of the bottom portion. In this case, the inclined portion may extend from the rising portion toward the outdoor side. In this configuration, the hollow portion is partitioned by the rising portion, so that water (liquid water) in the hollow portion tends to remain within the hollow portion. In such a situation, the effect of the present invention, which prevents water from entering the hollow portion, is more pronounced.

[0013] In addition, in the above-described parting mechanism, the gap between the bottoms of two adjacent fragments may be open. In such a configuration, water (liquid water) in the hollow portion may fall through the gap between the bottoms of two adjacent fragments and splash onto objects or people directly below. In such a situation, the effect of the present invention, which prevents water from entering the hollow portion, becomes even more significant. [Effects of the Invention]

[0014] According to the parting mechanism of the present invention, it is possible to prevent water such as rainwater from entering the space provided between the inclined portion and the bottom of the parting mechanism. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] <<Regarding a parting mechanism according to one embodiment of the present invention>> Hereinafter, a parting mechanism according to one embodiment of the present invention (hereinafter referred to as this embodiment) will be described with reference to FIGS. The embodiments described below are merely examples for facilitating understanding of the present invention and are not intended to limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit of the present invention. It goes without saying that the present invention also includes equivalents. Furthermore, the materials and shapes of the components used to implement the present invention may be freely set depending on the intended use of the present invention and the state of the art at the time of implementing the present invention.

[0017] In this specification, the terms "orthogonal," "vertical," and "parallel" include the range of error permitted in the technical field to which the present invention pertains. For example, in this specification, "orthogonal," "vertical," and "parallel" mean that the deviation is within a range of less than ±10° from the strict orthogonal, vertical, or parallel state. The deviation from the strict orthogonal or parallel state is preferably 5° or less, and more preferably 3° or less. In addition, in this specification, the meanings of "same," "identical," "match," and "equal" may include a range of error generally accepted in the technical field to which the present invention belongs. In addition, in this specification, the meanings of "all," "any," and "all" include not only 100% but also the range of error generally accepted in the technical field to which the present invention pertains, and may include, for example, 99% or more, 95% or more, or 90% or more.

[0018] In this embodiment, the "building" is assumed to be a residence. In this specification, "residence" includes a detached house and a single dwelling unit in an apartment building. It should be noted that the siding mechanism of the present invention can also be applied to buildings other than residences, such as stores, offices, commercial facilities such as movie theaters and department stores, public facilities such as hospitals and schools, factories, or buildings for various other purposes.

[0019] Furthermore, when describing the position, orientation, and state of each part of the guard mechanism below, unless otherwise specified, we will describe the position, orientation, and state when the guard mechanism is in use, specifically, when the guard mechanism is installed in the correct position.

[0020] The trim mechanism according to this embodiment (hereinafter referred to as trim mechanism 10) has the appearance shown in Fig. 1, and is used in a state where it is placed on the exterior wall of a house, specifically, below the vertical wall 1 that forms the eaves of the house, as shown in Fig. 2. The vertical wall 1 is made up of a multi-layered exterior wall panel 2, and as shown in Fig. 2, a batten (hereinafter referred to as a fixing batten 6) for fixing the trim mechanism 10 is attached to the underside of a frame 3 that forms the indoor end of the exterior wall panel 2. Also, as shown in Fig. 2, a batten (hereinafter referred to as a eaves batten 7) for fixing a soffit board is arranged adjacent to the fixing batten 6 on the indoor side.

[0021] As shown in Fig. 1, the parting mechanism 10 is configured by lining up a plurality of fragmentary members 12 in a row in the width direction of the vertical wall 1 (i.e., the width direction of the outer wall). A gap called a joint portion 36 is formed between two adjacent fragmentary members 12 in the width direction of the vertical wall 1. The allowable range of the width (length) of the joint portion 36 is 2 mm or less. Here, the width direction of the vertical wall 1 is the horizontal direction and is a direction perpendicular to the direction in which the eaves protrude toward the outdoors.

[0022] The basic structure of the parting mechanism 10 and its constituent fragment members 12 is generally the same as that of known parting mechanisms, except that it is equipped with a gap closing portion 40 and a damming portion 42, which will be described later. More specifically, each fragment member 12 is made of a metal plate, and more specifically, is made of aluminum formed into a predetermined shape.

[0023] As shown in Fig. 3, each fragmentary member 12 is made up of two separate members, an upper member 14 and a lower member 16. As shown in Fig. 2, the lower member 16 is fixed to a mounting hardware 18 with a screw. As shown in Fig. 2, the upper member 14 is fixed to the fixing crosspiece 6 via the mounting hardware 18 with a screw.

[0024] The mounting hardware 18 has a generally L-shape when viewed from the side (i.e., when viewed from the width direction of the vertical wall 1), and as can be seen from Fig. 2, its long side 20 extends toward the outdoors. The indoor end of the upper member 14 (more specifically, the bent portion 32 described below) is positioned directly below and overlaps the long side 20, and in this state, it is screwed to the fixing batten 6 together with the long side 20.

[0025] The defining feature of the parting mechanism 10 is the upper member 14, and therefore, in the following description, the upper member 14 and the configuration related to the upper member 14 will be described in more detail. The upper member 14 of each fragmentary member 12 is made of aluminum formed by extrusion or the like to have the shape shown in Fig. 3, specifically to form a hollow portion 44 and an open portion 46, which will be described later. Furthermore, as shown in Figs. 2 to 4, the upper member 14 of each fragmentary member 12 has an inclined portion 22, a hanging portion 24, a bottom portion 26, a rising portion 28, an end-side rising portion 30, a bent portion 32, and a protruding portion 34.

[0026] The inclined portion 22 is located directly below the decorative board 4 located closest to the exterior of the exterior wall panels 2 that form the vertical wall 1, and faces the underside of the decorative board 4 (i.e., the lower end of the vertical wall 1, which is the exterior wall). The inclined portion 22 extends from the vertical center of the rising portion 28 toward the exterior side, and descends as it approaches the exterior side. The inclined portion 22 protrudes toward the exterior side from the outdoor-side end face of the vertical wall 1, i.e., the outer surface of the decorative board 4, and the amount of protrusion (the length of the portion of the inclined portion 22 that protrudes toward the exterior side beyond the decorative board 4) is about several centimeters. The inclined portion 22 is located at a position slightly lower than the underside of the decorative board 4.

[0027] 2, a sealant 48 is filled between the upper surface of the inclined portion 22 and the lower surface of the decorative panel 4 to prevent rainwater and other water from seeping in between the inclined portion 22 and the decorative panel 4. The sealant 48 is a wet filler (a penetration prevention material), such as a known caulking material. However, the sealant is not limited to this, and a dry filler, such as a known gasket, may also be filled between the upper surface of the inclined portion 22 and the lower surface of the decorative panel 4.

[0028] As shown in Figures 1 to 4, hanging portion 24 is continuous with the outdoor-side end of inclined portion 22, and specifically, is a portion that hangs down vertically from the tip (outdoor-side end) of inclined portion 22 in the extension direction. As shown in Figure 2, hanging portion 24 is located at the outdoor-most side of upper member 14, in other words, it forms the outdoor-side end of border mechanism 10. Then, during rainy weather, rainwater that runs down decorative panel 4 of hanging wall 1 and falls onto inclined portion 22 flows along the upper surface of inclined portion 22 to the outdoor side, and then runs down hanging portion 24.

[0029] As shown in Figures 2 and 3, bottom portion 26 is located below inclined portion 22 and is a flat portion extending horizontally toward the outdoor side. Bottom portion 26 forms the base portion of upper member 14, and its outdoor end is joined to hanging portion 24 as shown in Figure 2. Furthermore, as shown in Figure 2, the indoor end of bottom portion 26 is located below fixing crosspiece 6, and more specifically, is located approximately directly below the point where bent portion 32 is screwed to fixing crosspiece 6 via long side portion 20 of mounting hardware 18. From the viewpoint of drainage, the upper surface of the bottom 26 or the bottom 26 itself may be slightly inclined relative to the horizontal direction.

[0030] The rising portion 28 is a portion that rises vertically upward from the upper surface of the bottom portion 26, and the upper end of the rising portion 28 reaches near the lower surface of the decorative board 4 of the exterior wall panel 2 that constitutes the vertical wall 1, as shown in Figure 2. The rising portion 28 is located slightly indoors relative to the outdoor-side end face of the vertical wall 1 (the outer surface of the decorative board 4), and is also located slightly outdoors relative to the rear surface (the indoor-side end face) of the decorative board 4. The rising portion 28 presses down on the above-mentioned sealant 48 from the indoor side, preventing the sealant 48 from protruding indoors.

[0031] 2 and 3, the rising portion 28, together with the bottom portion 26, the inclined portion 22, and the hanging portion 24, encloses a space (hereinafter, referred to as a hollow portion 44) that is substantially trapezoidal in side view. The hollow portion 44 is a space whose side ends (both ends in the width direction of the hanging wall 1) are open. Therefore, the hollow portions 44 of two adjacent fragments 12 communicate with each other.

[0032] As shown in Fig. 2, the end-side rising portion 30 is a portion that rises vertically upward from the upper surface of the bottom portion 26 at the indoor-side end of the bottom portion 26. The end-side rising portion 30 is provided with a drainage hole 38 shown in Fig. 4. The drainage hole 38 is provided at the side end of each fragment member 12 (the end in the width direction of the vertical wall 1), i.e., at a position shifted by several centimeters from the joint portion 36.

[0033] 2 and 3, the end-side rising portion 30, together with the bottom portion 26 and the rising portion 28, forms an open portion 46 that is substantially U-shaped in side view. The open portion 46 is a space whose side ends (ends in the width direction of the vertical wall 1) and upper end are open, and as shown in FIG. 2, the ventilation layer 5 of the exterior wall panel 2 that forms the vertical wall 1 is disposed directly above the open portion 46. Therefore, water (liquid water) that flows through the ventilation layer 5 falls and is then received in the open portion 46. Then, the water that accumulates in the open portion 46 is drained through the drainage holes 38 described above.

[0034] 2 and 3, the bent portion 32 extends horizontally from the upper end of the end-side rising portion 30 toward the indoor side, then bends in a generally L-shape and extends vertically downward. As described above, the bent portion 32 is located directly below the long side portion 20 of the mounting hardware 18, and is screwed to the fixing crosspiece 6 together with the long side portion 20.

[0035] As shown in Figures 2 and 3, the protruding portion 34 extends horizontally from the vertical center toward the indoor side. The amount of extension of the protruding portion 34 is about several centimeters, and the position where the protruding portion 34 is connected to the rising portion 28 is slightly higher than the position where the inclined portion 22 is connected to the rising portion 28. Then, as shown in Figure 2, the tip end (the indoor end) of the protruding portion 34 catches on the tip end (the outdoor end) of the long side portion 20 of the mounting hardware 18, so that the upper member 14 maintains an engaged state with the mounting hardware 18.

[0036] The characteristic configuration of the parting mechanism 10 in this embodiment will be described below. The parting mechanism 10 further includes a gap closing portion 40 shown in Figures 1 and 2 and a blocking portion 42 shown in Figures 2 and 4. The gap closing portion 40 is attached to the lower surface of each of the inclined portions 22 of two adjacent fragment members 12, straddling the joint portion 36 between the two fragment members 12. Specifically, the gap closing portion 40 is affixed to the lower surface of each inclined portion 22. The method of attaching the gap closing part 40 to the underside of the inclined part 22 is not particularly limited, and any method that can suitably attach the gap closing part 40 to the underside of the inclined part 22 can be freely used.

[0037] As described above, in this embodiment, the gap between the inclined portions 22 of two adjacent fragment members 12 (hereinafter referred to as the gap between the inclined portions) is blocked by the gap blocking portion 40. As a result, rainwater or the like is prevented from entering the hollow portion 44 through the gap between the inclined portions and remaining within the hollow portion 44, and it is possible to prevent liquid water within the hollow portion 44 from flowing out of the hollow portion 44 after rain, for example, and hitting objects or people located directly below the hollow portion 44.

[0038] Rainwater or the like that attempts to pass through the gap between the inclined portions hits gap closing portion 40 that closes the gap, and then flows along gap closing portion 40 to the outdoors. The rainwater flows along gap closing portion 40 until it reaches hanging portion 24, and then falls along hanging portion 24.

[0039] Furthermore, in this embodiment, no member equivalent to the gap closing portion 40 is attached to the upper surfaces of the bottoms 26 of two adjacent fragments 12. In other words, the gap between the bottoms 26 of the two fragments 12 (hereinafter, the gap between the bottoms) is open and not closed. In this case, if rainwater or the like infiltrates and remains inside the hollow portion 44, the water inside the hollow portion 44 may flow down through the gap between the bottoms. In such a situation, the effect of this embodiment, that is, the effect of preventing rainwater or the like from infiltrating into the hollow portion 44 by closing the gap between the inclined portions with the gap closing portion 40, becomes even more significant. However, the present invention is not limited to the above configuration, and the gap between the bottoms may also be closed by a member equivalent to the gap closing portion 40.

[0040] In this embodiment, in order to more effectively close the gap between the inclined portions, the gap closing portion 40 is made of a plate, more specifically, made of a plate whose surface is covered with a water-stopping material. The water-stopping material is, for example, a sheet or pad-shaped member, and in this embodiment, a foam-type water-stopping material is used. Examples of foam-type water-stopping materials include: Examples include EPDM (ethylene propylene rubber) foam material, etc. The waterproof material may cover at least the surface facing the lower surface of the inclined portion 22 among the six surfaces of the plate material constituting the gap closing portion 40, and more preferably, may also cover the outdoor-side end face and the indoor-side end face of the plate material.

[0041] Furthermore, the length of the plate material constituting the gap sealing portion 40, particularly the length in the width direction of the vertical wall 1, only needs to be long enough to seal the gap between the inclined portions, and at least be longer than the width of the gap between the inclined portions, i.e., the width of the joint portion 36.

[0042] On the other hand, it is preferable that the length of the board in the direction in which the eaves protrude is the same as the length (extension) of the inclined portion 22 in the same direction. In this case, the gap closing portion 40 closes the gap between the inclined portions from the indoor end to the outdoor end, as shown in Figure 1. With this configuration, the gap between the inclined portions can be more reliably closed by the gap closing portion 40, and therefore the intrusion of rainwater and the like into the hollow portion 44 can be more effectively prevented.

[0043] The damming portion 42 is a plate- or pad-shaped member made of a water-stopping material, particularly a foam-type water-stopping material, and is attached, more specifically, pasted, to the upper surface of the bottom portion 26. The foam-type water-stopping material that constitutes the damming portion 42 can be made of the same type of material as that used for the gap closing portion 40. The method of attaching the damming portion 42 to the upper surface of the bottom portion 26 is not particularly limited, and any method that can suitably attach the damming portion 42 to the upper surface of the bottom portion 26 can be freely used.

[0044] 4, the damming portion 42 is provided in the width direction of the vertical wall 1, from the side end of the upper member 14 to the position where the drainage hole 38 is provided. Furthermore, the damming portion 42 is provided with one end contacting the rising portion 28 and the other end contacting the end-side rising portion 30 in the protruding direction of the eaves. In other words, the damming portion 42 is provided in a continuous state from the indoor-side end of the open portion 46 to the outdoor-side end. Furthermore, as shown in FIG. 4, the damming portion 42 has a slight thickness, and specifically, the thickness corresponds to the distance from the top surface of the bottom portion 26 to the lower end of the drainage hole 38.

[0045] The provision of the damming portion 42 described above prevents rainwater and other liquid water that has accumulated in the open portion 46 from flowing toward the side edge of the upper member 14, and allows the water to be properly discharged through the drain hole 38. This makes it possible to prevent the water in the open portion 46 from flowing down from the joint portion 36 (more specifically, the gap between the bottom portions) and hitting objects or people located directly below the joint portion 36.
