[0010] Hereinafter, embodiments of a surface grille mounting structure including a bracket structure of the present disclosure will be described with reference to the accompanying drawings. Note that the surface grille mounting structure including a bracket structure of the present disclosure is not limited to the configurations described in the following embodiments.

[0011] (Embodiment) 1 to 3 are perspective views of a building 2 provided with a surface grille mounting structure including a bracket structure according to an embodiment.

[0012] The building 2 shown in Figures 1 to 3 is a building such as a house, and is equipped with ALC panels 4 as exterior walls. As shown in Figures 1 to 3, an opening 6 is provided in the ALC panel 4, and a grille 8 is attached to the outdoor side of the opening 6. Figures 1 and 3 show the grille 8 in a closed position, and Figure 2 shows the grille 8 in an open position.

[0013] As shown in FIG. 3, the opening 6 is provided with L-shaped angles 10 and 12 .

[0014] The L-shaped angles 10, 12 are metal reinforcing members for reinforcing the strength of the ALC panel 4. The L-shaped angles 10, 12 include a pair of L-shaped angles 10 extending vertically and a pair of L-shaped angles 12 extending horizontally.

[0015] The above-mentioned grille 8 is attached to a pair of L-shaped angles 10 extending vertically via bracket structures 14 and 15.

[0016] The bracket structures 14 and 15 are used to attach the grille 8 to the L-shaped angle 10. Each of the bracket structures 14 and 15 is formed by combining a plurality of brackets.

[0017] Bracket structure 14 is provided above opening 6 and attaches the upper part of grille 8 to L-shaped angle 10. Bracket structure 15 is provided below opening 6 and attaches the lower part of grille 8 to L-shaped angle 10. Bracket structure 14 is also referred to as the "upper bracket structure 14," and bracket structure 15 is also referred to as the "lower bracket structure 15."

[0018] The structure for fixing the grille 8 to the L-shaped angle 10, including the bracket structures 14 and 15, is referred to as the "grating attachment structure."

[0019] FIG. 4 is a longitudinal sectional view schematically showing the peripheral structure of the surface grating 8, and FIG. 5 is a transverse sectional view schematically showing the peripheral structure of the surface grating 8. As shown in FIG.

[0020] 4, the upper bracket structure 14 includes a base bracket 19 and a pivot bracket 20. The lower bracket structure 15 includes a base bracket 19 and a fixed bracket 22.

[0021] The base bracket 19 is a bracket for fixing the bracket structures 14, 15 to the L-shaped angle 10. The base bracket 19 is common to both the upper bracket structure 14 and the lower bracket structure 15, and has the same structure.

[0022] The pivoting bracket 20 is a bracket that pivotally connects the upper part of the surface grille 8 to the base bracket 19. The pivoting bracket 20 is rotatable around a rotation axis (rotation axis Ax1 shown in FIG. 11) that extends horizontally. The fixed bracket 22 is a bracket that fixedly connects the lower part of the surface grille 8 to the base bracket 19. The fixation of the surface grille 8 by the fixed bracket 22 can be released by working from inside the room.

[0023] When the surface grille 8 is released from the fixed bracket 22, it can rotate about the rotating bracket 20 between the closed position shown in FIG. 1 and the open position shown in FIG.

[0024] As shown in Figures 4 and 5, a sash frame 18 (not shown in Figures 1 to 3) is attached to the opening 6. The sash frame 18 is a frame member for holding a window (not shown).

[0025] The mounting order is as follows: first, the bracket structures 14, 15 are mounted to the opening 6, then the sash frame 18 is mounted to the opening 6, and then the grille 8 is mounted to the bracket structures 14, 15.

[0026] A closing material 24 is further attached to the grille 8. The closing material 24 is a member for sealing the gap between the grille 8 and the ALC panel 4. As shown in Figs. 1 and 2, in this embodiment, one closing material 24 is provided on each of the left and right ends of the grille 8 (two in total).

[0027] As shown in FIG. 4, the closing member 24 is attached to the vertical side 28 of the grille 8 on the indoor side by a fixing member 26 made of a screw or plate material.

[0028] (About base brackets) Next, the base bracket 19 will be described with reference to FIGS. 6 to 8 and 9A to 9C.

[0029] 6 and 7 are perspective views showing the structure around the base bracket 19, and FIG. 8 is a perspective view showing the base bracket 19 in an exploded state.

[0030] As shown in FIGS. 6 to 8, the base bracket 19 includes a first bracket 30, a second bracket 32, and a fixing member .

[0031] The first bracket 30 is fixed to the first portion 10A of the L-shaped angle member 10 on the indoor side. The second bracket 32 ​​is fixed to the second portion 10B of the L-shaped angle member 10 on the outdoor side. Both brackets 30 and 32 are made by bending a metal plate. The fixing member 34 is a member that fixes the first bracket 30 and the second bracket 32 ​​to each other.

[0032] As shown in FIG. 8, the first bracket 30 has a first main body portion 36, a first insertion portion 37, and a bent portion 38.

[0033] The first main body portion 36 is a portion that is arranged along the first portion 10A of the L-shaped angle member 10. The first insertion portion 37 is a portion that is inserted into the gap between the first portion 10A of the L-shaped angle member 10 and the first surface 4A of the ALC panel 4. In this embodiment, the first insertion portion 37 is a pair of claws formed by folding back the first end of the first main body portion 36 in opposite directions. The bent portion 38 is a portion that is formed by folding back the second end of the first main body portion 36, and is bent approximately 90 degrees in a direction away from the first portion 10A.

[0034] The second bracket 32 ​​has a second main body portion 40, a second insertion portion 42, and a fixing portion 44.

[0035] The second main body portion 40 is a portion that is arranged along the second portion 10B of the L-shaped angle member 10. The second insertion portion 42 is a portion that is inserted into the gap between the second portion 10B of the L-shaped angle member 10 and the second surface 4B of the ALC panel 4. In this embodiment, the second insertion portion 42 is a pair of claws that are formed by folding back the first end of the second main body portion 40 in opposite directions. The fixed portion 44 is a portion that is fixed to the swivel bracket 20 or the fixed bracket 22. In this embodiment, the fixed portion 44 is a portion that extends from the first end of the second main body portion 40.

[0036] The fixing portion 44 protrudes in a predetermined direction (arrow A1) from the main body portion 40 and is an extension of a portion in the width direction (arrow A2) that intersects with the protruding direction of the main body portion 40. The second insertion portions 42 are portions of the main body portion 40 where the remaining portion in the width direction is folded back in the opposite direction, and are located at both ends in the width direction.

[0037] The bent portion 38 of the first bracket 30 has a plurality of screw holes 39. The main body portion 40 of the second bracket 32 ​​has a plurality of elongated holes 46 corresponding to the screw holes 39. In this embodiment, three screw holes 39 and three elongated holes 46 are provided.

[0038] The fixing members 34 in this embodiment are screws that are inserted through the elongated holes 46 and screwed into the screw holes 39. This allows the first bracket 30 and the second bracket 32 ​​to be fixed to each other.

[0039] 9A to 9C are cross-sectional views illustrating a method for fixing base bracket 19. FIG.

[0040] 9A, the first insertion portion 37 of the first bracket 30 is inserted into the gap between the first portion 10A of the L-shaped angle 10 and the first surface 4A of the ALC panel 4 (arrow B1). Similarly, the second insertion portion 42 of the second bracket 32 ​​is inserted into the gap between the second portion 10B of the L-shaped angle 10 and the second surface 4B of the ALC panel 4 (arrow B2).

[0041] A tool such as a hammer may be used to insert the insertion portions 37, 42. By inserting the insertion portions 37, 42 into the gaps using a tool such as a hammer, the insertion portions 37, 42 can be inserted all the way.

[0042] 9B, the bent portion 38 of the first bracket 30 and the end of the main body portion 40 of the second bracket 32 ​​face each other, and the screw hole 39 of the bent portion 38 overlaps with the elongated hole 46 of the main body portion 40. In this state, the screw portion of the fixing member 34 is inserted into the elongated hole 46 of the main body portion 40 and screwed into the screw hole 39 of the bent portion 38.

[0043] 9C, by tightening the fixing member 34, the first insertion portion 37 of the first bracket 30 and the second insertion portion 42 of the second bracket 32 ​​are each inserted toward the back of the L-shaped angle bracket 10 (arrows B3 and B4). This allows the first bracket 30 and the second bracket 32, which are hooked onto the L-shaped angle bracket 10, to be fixed to each other.

[0044] According to the above-described configuration and method, the base bracket 19 can be easily fixed to the L-shaped angle 10 without having to process the L-shaped angle 10 itself, as is the case with conventional methods such as welding. This improves the workability when installing the grille 8 using the L-shaped angle 10.

[0045] (Rotating bracket, fixed bracket) Next, the rotating bracket 20 and the fixed bracket 22 will be described with reference to FIGS.

[0046] 10 and 11 are perspective views showing the surrounding structure of the rotating bracket 20 and the fixed bracket 22. FIG.

[0047] As shown in FIGS. 10 and 11, the pivot bracket 20 has two plate portions 56 and 58.

[0048] The plate portion 56 is the portion that is fixed to the fixing portion 44 of the base bracket 19 described above. The plate portion 57 is provided with an elongated hole 60, through which a fixing member 90 such as a screw shown in Fig. 4 is inserted. In this embodiment, the elongated hole 60 extends vertically.

[0049] Plate portion 58 is the portion that is fixed to vertical side 28 of grille 8, and a back plate 59 shown in Figure 11 is connected to it. Back plate 59 is placed in opening 51 in vertical side 28 shown in Figure 10, and back plate 59 and plate portion 58 are slid up and down along vertical groove 52 that is narrower than opening 51, and then the screw connected to back plate 59 is tightened. This allows swivel bracket 20 to be fixed to vertical side 28 of grille 8.

[0050] The fixed bracket 22 has two plate portions 62 and 64 .

[0051] The plate portion 62 is the portion that is fixed to the fixing portion 44 of the base bracket 19 described above, and has an elongated hole 65 for inserting a fixing member 92 such as a screw shown in Fig. 4. In this embodiment, the elongated hole 65 extends horizontally.

[0052] The plate portion 64 is a portion that is fixed to the vertical side 28 of the surface grille 8. The plate portion 64 is fixed to the vertical side 28 of the surface grille 8 by a slide bracket 66.

[0053] The slide bracket 66 is a bracket for detachably attaching the plate portion 64 of the fixed bracket 22 to the vertical side 28 of the surface grille 8. The slide bracket 66 is provided so as to be slidable in the vertical direction (arrow A3) in the vertical groove 52 of the vertical side 28 of the surface grille 8.

[0054] (About the slide bracket) The slide bracket 66 will be described with reference to FIGS. 12 to 15 and 16A to 18B.

[0055] 12 and 13 are perspective views of the slide bracket 66, and FIGS. 14 and 15 are exploded perspective views of the slide bracket 66. FIG.

[0056] As shown in FIGS. 12 to 15, the slide bracket 66 has a first slide plate 70, a second slide plate 72, a first connecting member 74, a second connecting member 76, and a liner 78.

[0057] The first sliding plate 70 is a plate-like member that is arranged inside the vertical grooves 52 of the surface grille 8 shown in Figures 10 and 11. The second sliding plate 72 is a plate-like member that is arranged outside the vertical grooves 52 of the surface grille 8. As shown in Figures 14 and 15, the first sliding plate 70 has a plurality of screw holes 80, and the second sliding plate 72 has a plurality of through holes 82. The first sliding plate 70 and the second sliding plate 72 are connected by two connecting members 74, 76.

[0058] The connecting members 74, 76 are each a member that connects the first sliding plate 70 and the second sliding plate 72 in an adjustable manner so that the distance between them is adjusted. In this embodiment, the connecting members 74, 76 are each a screw that is inserted into a through-hole 82 in the second sliding plate 72 and threaded into a screw hole 80 in the first sliding plate 70. The connecting members 74, 76 are each a different type of screw, with the first connecting member 74 being a thumbscrew for manual use and the second connecting member 76 being a screw for use with tools.

[0059] In the assembled state shown in Figures 12 and 13, by rotating the connecting members 74, 76, the position at which the connecting members 74, 76 screw into the first slide plate 70 can be changed, and the distance between the first slide plate 70 and the second slide plate 72 can be adjusted.

[0060] The liner 78 is a plate-like member disposed between the first sliding plate 70 and the second sliding plate 72. Providing the liner 78 ensures that the distance between the first sliding plate 70 and the second sliding plate 72 is equal to or greater than a predetermined distance. A through hole 84 is formed in the liner 78, and the first connecting member 74 is inserted through the through hole 84.

[0061] 16A to 18B are respectively a perspective view and a vertical cross-sectional view for explaining a method for fixing the surface grille 8 with the slide bracket 66. Figures 16A, 17A, and 18A are perspective views, and Figures 16B, 17B, and 18B are vertical cross-sectional views.

[0062] 16A and 16B, the surface grille 8 is in an open position, and the vertical side 28 of the surface grille 8 is separated from the fixed bracket 22. The slide bracket 66 is temporarily fixed to the vertical side 28 of the surface grille 8. As shown in FIG. 16B, with the first slide plate 70 of the slide bracket 66 positioned inside the vertical groove 52 of the vertical side 28 and the second slide plate 72 positioned outside the vertical groove 52, the connecting members 74, 76 are tightened to sandwich the vertical side 28 between the two slide plates 70, 72, and the slide bracket 66 is temporarily fixed to the vertical side 28. The position at which the slide bracket 66 is temporarily fixed is below the position at which the fixed bracket 22 contacts or faces it.

[0063] 16A and 16B, the worker holds the lower part of the surface grille 8 and rotates it in the direction (arrow A4) that brings the vertical side 28 of the surface grille 8 closer to the fixed bracket 22. This results in the state shown in FIGS. 17A and 17B.

[0064] 17A and 17B, the plate portion 64 of the fixed bracket 22 faces and contacts the vertical sides 28 and vertical grooves 52 of the surface grille 8. In this state, the fastening by the connecting members 74, 76 is loosened to release the temporary fixation of the slide bracket 66, and the slide bracket 66 is moved upward (arrow A5). This results in the state shown in FIGS. 18A and 18B.

[0065] 18A and 18B, the plate portion 64 of the fixed bracket 22 is disposed between the vertical side 28 of the surface grille 8 and the second sliding plate 72 of the sliding bracket 66. A liner 78 is provided on the sliding bracket 66, allowing the sliding bracket 66 to move smoothly.

[0066] In this state, by tightening the connecting members 74, 76, the plate portion 64 of the fixed bracket 22 is sandwiched between the vertical side 28 and the second sliding plate 72, fixing the plate portion 64. This fixes the surface grille 8 having the sliding bracket 66 and the fixed bracket 22 having the plate portion 64 to each other, and the surface grille 8 can be fixed in the closed position.

[0067] 16A to 18B can be released by reversing the procedure shown in Figures 16A to 18B. That is, from the state shown in Figures 18A and 18B, the fastening of the connecting members 74, 76 is loosened to release the fastening by the slide bracket 66, and then the slide bracket 66 is slid downward. After moving the slide bracket 66 downward, one of the connecting members 74, 76 is fastened temporarily to the vertical side 28. By releasing the fastening by the slide bracket 66, the surface grille 8 can be moved from the closed position to the open position.

[0068] According to the above configuration and method, the surface grille 8 and the fixed bracket 22 are releasably fixed to each other using the slide bracket 66 arranged in the vertical groove 52 of the surface grille 8. In particular, because it is sufficient to fix the plate portion 64 of the fixed bracket 22 by sandwiching it between the vertical side 28 and the second slide plate 72, high precision is not required in aligning the surface grille 8 and the fixed bracket 22 compared to the conventional method of aligning the through holes of the two brackets. As a result, even an inexperienced worker can easily perform the operations of fixing and releasing the surface grille 8, improving the workability involved in installing the surface grille 8.

[0069] (Action / Effect 1: Base bracket) As described above, the bracket structures 14, 15 of this embodiment are bracket structures for attaching a grille 8 to an L-shaped angle 10 provided in an opening 6 of an ALC panel 4, and include a first bracket 30 inserted into the gap between the first part 10A on the indoor side of the L-shaped angle 10 and the first surface 4A of the ALC panel 4, a second bracket 32 ​​inserted into the gap between the second part 10B on the outdoor side of the L-shaped angle 10 and the second surface 4B of the ALC panel 4, a fixing member 34 (first fixing member) that fixes the first bracket 30 and the second bracket 32 ​​to each other, a rotating bracket 20 or a fixed bracket 22 (third bracket) that is attached to the grille 8, and fixing members 90, 92 (second fixing members) that fix the second bracket 32 ​​and the rotating bracket 20 or the fixed bracket 22 to each other.

[0070] With this configuration, the first bracket 30 and the second bracket 32 ​​are fixed integrally to the L-shaped angle 10, and then the rotating bracket 20 or the fixed bracket 22 is fixed to the second bracket 32, thereby making it possible to fix the surface grille 8 to the L-shaped angle 10. This method makes it easier to attach the surface grille 8 than by methods that require processing of the L-shaped angle 10 itself, such as welding, and improves the workability involved in attaching the surface grille 8.

[0071] In bracket structures 14 and 15 of the present embodiment, first bracket 30 has a plate-like first main body portion 36 arranged along the surface of first portion 10A and a first insertion portion 37 folded back from first main body portion 36 and inserted into the gap, second bracket 32 ​​has a plate-like second main body portion 40 arranged along the surface of second portion 10B and a second insertion portion 42 folded back from second main body portion 40 and inserted into the gap, and fixing member 34 (first fixing member) fixes first main body portion 36 and second main body portion 40 to each other. This configuration makes it easier to firmly fix the two brackets to each other.

[0072] In bracket structures 14, 15 of the present embodiment, first main body portion 36 has a bent portion 38 bent in a direction away from first portion 10A, and fixing member 34 (first fixing member) fixes bent portion 38 of first main body portion 36 to a portion of second main body portion 40 extending toward the interior of the room. This configuration reduces the amount by which first bracket 30 and second bracket 32 ​​penetrate inside opening 6 of ALC panel 4, ensuring space for arranging other components such as sash frame 18 after surface grille 8 is installed.

[0073] In the bracket structures 14 and 15 of the present embodiment, the bent portion 38 has a screw hole 39, and the second main body portion 40 has an elongated hole 46 that faces the screw hole 39. This configuration makes it easy to align the first bracket 30 and the second bracket 32. Furthermore, since the screw fastening work can be performed from the inside of the room, workability is also improved.

[0074] In bracket structures 14 and 15 of the present embodiment, second bracket 32 ​​has a fixing portion 44 that protrudes from second main body portion 40 toward the exterior side and is fixed to rotating bracket 20 or fixed bracket 22 (third bracket). With this configuration, by fixing second bracket 32 ​​and third bracket to each other at a position further exterior than second main body portion 40, a large space can be secured for the fixing work, improving workability.

[0075] In the bracket structures 14 and 15 of the present embodiment, the fixing portion 44 of the second main body portion 40 is a portion extending in the width direction perpendicular to the protruding direction, and the second insertion portion 42 is a portion obtained by folding back the remaining portion in the width direction. With this configuration, the length of the second main body portion 40 in the width direction can be effectively utilized to provide the fixing portion 44 and the second insertion portion 42.

[0076] (Action / Effect 2: Slide bracket) As described above, the surface grille mounting structure of this embodiment comprises the bracket structures 14, 15 provided at the opening 6 of the building 2, and the slide bracket 66 connected to the bracket structures 14, 15 and slidable along the vertical grooves 52 of the vertical sides 28 provided on the indoor side of the surface grille 8 in the surface grille 8 that is rotatable between an open position and a closed position. The bracket structure 15 has a plate portion 64 that faces the vertical grooves 52 of the surface grille 8 in the closed position, and the slide bracket 66 slides along the vertical grooves 52 of the vertical sides 28 provided on the indoor side of the surface grille 8. The grille 8 is provided with a first sliding plate 70 arranged on the inside, a second sliding plate 72 arranged on the outside of the vertical groove 52, and connecting members 74, 76 that connect the first sliding plate 70 and the second sliding plate 72 in a variable manner. With the plate portion 64 sandwiched between the vertical side 28 of the grille 8 and the second sliding plate 72 of the slide bracket 66, the connecting members 74, 76 are used to narrow the gap between the first sliding plate 70 and the second sliding plate 72, thereby sandwiching the plate portion 64 and fixing the grille 8 in the closed position.

[0077] According to this configuration, the grille 8 can be easily attached to the opening 6 of the building 2, and the workability involved in attaching the grille 8 can be improved.

[0078] In the surface grille mounting structure of this embodiment, the connecting members 74, 76 widen the gap between the first sliding plate 70 and the second sliding plate 72, thereby opening the plate portion 64 and sliding the slide bracket 66, thereby releasing the fixed surface grille 8. With this configuration, the fixed surface grille 8 can be easily released.

[0079] In the surface grille mounting structure of this embodiment, the first sliding plate 70 has a screw hole 80, the second sliding plate 72 has a through hole 82, and the connecting members 74, 76 are screws that thread into the screw hole 80 through the through hole 82. With this configuration, the distance between the first sliding plate 70 and the second sliding plate 72 can be easily adjusted.

[0080] In the surface grille mounting structure of this embodiment, the connecting members 74, 76 include a first connecting member 74 and a second connecting member 76 that are provided at different positions in the vertical direction along which the vertical sides 28 extend. With this configuration, the surface grille 8 can be firmly fixed by providing two types of connecting members, and it is also possible to temporarily fix the surface grille 8 using one of the connecting members.

[0081] In the surface grille mounting structure of this embodiment, the first connecting member 74 is a manual thumbscrew, and the second connecting member 76 is a tool screw. With this configuration, the thumbscrew can be used to easily fasten the grille, while the tool screw can be used to prevent the grille from being easily released from the outside, thereby improving security.

[0082] In the surface grille mounting structure of this embodiment, the second sliding plate 72 is longer than the first sliding plate 70. With this configuration, the second sliding plate 72 only needs to have the length necessary to sandwich the plate portion 64, while the first sliding plate 70 only needs to have the length necessary to maintain integration with the second sliding plate 72, which allows the size and weight of the sliding bracket 66 to be kept low and improves the operability of the sliding bracket 66.

[0083] In the surface grille mounting structure of this embodiment, the slide bracket 66 further includes a liner 78 for ensuring a gap between the vertical side 28 and the second slide plate 72. With this configuration, it is possible to ensure a space for arranging the plate portion 64.
