[0010] Embodiments of the present invention will now be described based on the drawings. As shown in Figures 1 to 3, the fitting of this embodiment is a back door 1. The back door 1 comprises a door frame 10 installed in the back door opening of a building, and a door body 20 placed inside the door frame 10. The door frame 10 is formed in a rectangular frame shape by framing an upper frame 11, a lower frame 12, and left and right vertical frames 13, 14 made of synthetic resin by welding or the like. The door body 20 includes a panel holding frame 20A formed by framing an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24 by welding or the like, and a panel 25 held inside the panel holding frame 20A. The vertical frame 23 is the vertical frame on the hanging end side that is pivotally connected to the door frame 10 by a hinge, and the vertical frame 24 is the vertical frame on the door tip side. The panel 25 is triple glass in this embodiment, but may be multilayer glass or single-pane glass, or even a panel made of a material other than glass such as synthetic resin. A handle 26 is attached to the vertical frame 24.

[0011] The upper frame 21, the lower frame 22, and the vertical frames 23, 24 include a frame body 30 and a pressing edge 38. The frame bodies 30 of each frame have the same cross-sectional shape, and the pressing edges 38 also have the same cross-sectional shape. Therefore, in FIG. 4, the main part of the frame body 30 of the lower frame 22 is shown. The frame body 30 has a cross-sectional shape having a plurality of hollow portions and is composed of an extruded shape made of synthetic resin. As shown in FIG. 4, it includes a first expected surface portion 31, a support protrusion 32, an engagement groove portion 33, a second expected surface portion 34, and a pressing edge attachment groove portion 35. The first expected surface portion 31 is a portion formed along the inner peripheral surface of the framed door body 20, and the surface facing the outer peripheral surface of the panel 25 on the first expected surface portion 31 is the first expected surface 311. The support protrusion 32 is a substantially hollow rectangular protrusion formed by protruding from the indoor side end of the first expected surface portion 31 toward the inner peripheral side (inside the plane direction) of the door body 20. The inner peripheral side (inside the plane direction) of the door body 20 is the direction downward in the upper frame 21, upward in the lower frame 22, and toward the other vertical frames 24, 23 on the opposite side in the vertical frames 23, 24. Two fin-shaped seal pieces 321 that contact the indoor surface of the panel 25 are respectively formed on the support protrusion 32.

[0012] The engagement groove portion 33 includes a first side surface portion 331, a bottom surface portion 332, and a second side surface portion 333, and defines and forms a concave groove that opens to the inner peripheral surface of the door body 20. The first side surface portion 331 extends to the outer peripheral side substantially orthogonal to the prospective direction from the outdoor side end portion of the first prospective surface portion 31. The bottom surface portion 332 extends from the first side surface portion 331 in the outdoor direction. The second side surface portion 333 extends from the bottom surface portion 332 to the inner peripheral side. Note that the second side surface portion 333 is provided so as to be inclined gradually toward the outdoor side from the base end portion connected to the bottom surface portion 332 toward the tip end portion. A locking piece portion 334 protruding toward the first side surface portion 331 side is formed at the tip end portion (inner peripheral side end portion) of the second side surface portion 333. The second prospective surface portion 34 is constituted by the tip end portion of the second side surface portion 333. The inner peripheral surface of the second prospective surface portion 34 is the second prospective surface 341. The second prospective surface 341 is provided on the extension line of the first prospective surface 311 with the concave groove partitioned by the engaging groove portion 33 interposed therebetween. In addition, as shown in FIG. 5, a positioning groove portion 345 for arranging the setting block 40 at a predetermined position in the longitudinal direction of the frame body 30 is formed in the second prospective surface portion 34 and the second side surface portion 333. The positioning groove portion 345 is formed by performing drilling from the second prospective surface 341 of the second prospective surface portion 34. Note that the drilling is also performed on the bottom surface portions 332 and 333 and is communicated with the hollow portion of the frame body 30.

[0013] As shown in FIG. 4, the edge mounting groove portion 35 includes the second side surface portion 333, the bottom surface portion 352, and the outdoor piece portion 353, and defines a concave groove that opens to the inner peripheral surface of the door body 20. The bottom surface portion 352 extends from the bottom surface portion 332 to the outdoor side. The outdoor piece portion 353 protrudes from the outdoor side end portion of the bottom surface portion 352 to the inner peripheral side of the door body 20.

[0014] The trim strip 38 is made of an extruded profile made of synthetic resin. As shown in Figures 2 and 3, the base end of the trim strip 38 is attached to the trim strip mounting groove 35. A fin-shaped sealing piece 381 that contacts the panel 25 is formed on the tip end of the trim strip 38. When the trim strip 38 is attached to the frame body 30, a retaining groove is formed between the support projection 32 and the trim strip 38 to hold the panel 25. The interior surface of the panel 25 is supported by the support projection 32, and the exterior surface of the panel 25 is supported by the trim strip 38. In addition, the sealing pieces 321 and 381 contact the interior and exterior surfaces of the panel 25, ensuring airtightness and watertightness between the panel 25 and the door body 20.

[0015] The door body 20 is fitted with setting blocks 40 that support the panel 25 so that it does not move in the in-plane direction. In the back door 1 of this embodiment, as shown by the dotted lines in Figure 1, the setting blocks 40 are attached to the leading edge side of the upper frame 21, the hinge side of the lower frame 22, and the upper and lower ends of the vertical frames 23 and 24, respectively. As shown in Figures 5 and 6, a set plate 60, described later, is positioned between the setting block 40, which is attached to the door edge side of the upper frame 21 and the upper end side of the vertical frame 24 on the door edge side, and the outer surface of the panel 25. In addition, a panel retaining member 80, described later, is attached to the setting block 40 attached to the vertical frames 23 and 24 with anti-theft screws 90. Figure 6 is an exploded perspective view showing the setting block 40, set plate 60, and panel retaining member 80 attached to the upper end side of the vertical frame 24.

[0016] [Setting Block] The setting block 40 is an injection-molded product made of synthetic resin, and as shown in Figures 7 and 8, it comprises a main body portion 41, two claw portions 42, and a protruding portion 43. The main body 41 is formed in a roughly rectangular plate shape and includes a surface 411 on which the panel 25 and set plate 60 are arranged, a bottom surface 412 that abuts against the first visible surface 311 of the first visible surface 31 of the frame body 30, and a mounting surface 413 to which the panel retaining material 80 is attached. The main body 41 includes an interior surface 414 formed parallel to the mounting surface 413 and facing the support projection 32 of the frame body 30, and two side surfaces 415 perpendicular to the interior surface 414. The main body 41 is equipped with a rib structure in order to ensure strength while reducing the amount of resin material used. For this reason, the surface 411 is roughly flat and has four holes for weight reduction. The bottom surface 412 is composed of the bottom portions of each rib. The mounting surface 413 is the exterior side of the main body 41 and has two screw holes 416 into which security screws 90 are screwed. Recesses 417 are formed between the mounting surface 413 and each claw portion 42. Furthermore, the thickness dimension of the main body 41 may be set to multiple types depending on the type of door or window in which the setting block 40 is to be installed. For example, two types of setting blocks 40 with thickness dimensions of 8 mm and 10 mm for the main body 41 may be prepared and selected according to the type of door or window in question.

[0017] The claw portion 42 is provided in pairs on the left and right sides of the mounting surface 413 and comprises an elastic piece portion 421, a contact surface portion 422, and a hook portion 423. The elastic piece portion 421 extends from the main body portion 41 toward the outside and further extends toward the outer circumference (outward in the in-plane direction). The contact surface portion 422 is the portion that extends from the tip of the elastic piece portion 421 toward the main body portion 41, and its lower surface is formed on the extension of the bottom surface 412. The hook portion 423 extends from the contact surface portion 422 and is shaped to engage with the locking piece portion 334.

[0018] As shown in Figures 4 and 7 and 8, the protruding portion 43 comprises a contact plate portion 431, a plate portion 432, and a guide portion 433. The contact plate portion 431 extends from the bottom surface 412 of the main body portion 41 and is formed in a plate shape along the indoor-outdoor direction. This contact plate portion 431 protrudes from the bottom surface 412 of the main body portion 41 and is configured to contact the second visible surface 341 during the installation of the setting block 40, as will be described later. The plate portion 432 extends from the bottom surface 412 and is provided continuously with the interior surface of the contact plate portion 431. The plate portion 432 is the part that contacts the first side surface 331 of the engagement groove portion 33 when the setting block 40 is attached to the frame body 30. The plate portion 432 is formed in a plate shape that is wider than the contact plate portion 431, and is configured to increase the contact area when it contacts the first side surface 331. In addition, the bottom surface side of the plate portion 432 protrudes from the bottom surface of the contact plate portion 431.

[0019] The guide portion 433 is configured to be positioned in a positioning groove 345 formed in the second side portion 333, and is the part that determines the position of the setting block 40 in the longitudinal direction of the frame body 30. As a result, the setting block 40 is positioned in a predetermined position in the longitudinal direction of the frame body 30. In addition, the guide portion 433 is triangular in side view when viewed from the outside, and the side surfaces 4331 of the guide portion 433 are inclined to move closer to each other from the inner circumference to the outer circumference. Since the width dimension of the guide portion 433 gradually decreases toward the outer circumference, the gap between the guide portion 433 and the positioning groove 345 is configured to gradually increase toward the outer circumference. Therefore, even if rainwater enters the engagement groove 33, this rainwater can be discharged to the trim mounting groove 35 side through the gap between the guide portion 433 and the positioning groove portion 345. In this embodiment, although not shown, through holes are formed in the bottom portion 332 and bottom portion 352 corresponding to the position of the positioning groove portion 345, and rainwater that flows into the positioning groove portion 345 is drained to the outside through the through holes in the bottom portions 332 and 352 and the hollow portion of the frame body 30.

[0020] As shown in FIG. 4, the width dimension between the first side surface portion 331 and the locking piece portion 334 of the frame body 30 is set as W1, and the width dimension between the contact surface that contacts the first side surface portion 331 in the plate portion 432 of the setting block 40 and the engaging portion that engages with the locking piece portion 334 in the hook portion 423 is set as W2. It is designed such that W1 < W2. In this embodiment, the width dimension W2 is set to be 1 mm larger than the width dimension W1. Therefore, when the claw portion 42 and the protruding portion 43 of the setting block 40 are inserted into the engaging groove portion 33 of the frame body 30, the claw portion 42 is elastically deformed, and due to its repulsive force, the plate portion 432 and the claw portion 42 are pressed against the first side surface portion 331 and the locking piece portion 334 with a predetermined force, and the mounting strength of the setting block 40 can be increased.

[0021] [Setting Plate] The setting plate 60 is an injection molded product made of synthetic resin, and is a component that prevents the door from sagging by being inserted into the upper part of the door tip of the door body 20. That is, in the cantilevered door body 20 or shoji supported by the door frame 10 by the vertical frame 23 on the hanging side, if there is a slight gap between the outer peripheral surface on the upper part of the door tip side of the panel 25 and the setting block 40, the door tip side of the door body 20 may sag, and the upper frame 21, lower frame 22, vertical frames 23, 24 may deform like a parallelogram. Therefore, as shown in FIGS. 1 and 5, between the setting block 40 attached to the door tip side of the upper frame 21, which is the upper part of the door tip of the door body 20, and the upper surface of the panel 25, and between the setting block 40 attached to the upper end side of the vertical frame 24 and the side surface of the panel 25, setting plates 60 are respectively arranged. In this embodiment, three setting plates 60 are stacked and arranged between the setting block 40 of the upper frame 21 and the panel 25, and two setting plates 60 are stacked and arranged between the setting block 40 of the vertical frame 24 and the panel 25.

[0022] As shown in FIG. 9, the setting plate 60 includes a flat plate portion 61 and a pair of inclined surface portions 62 extending obliquely from both ends in the longitudinal direction of the flat plate portion 61. As shown in Figure 10, the flat plate portion 61 has an outer surface 611 and an inner surface 612 parallel to the outer surface 611. The outer surface 611 is the surface on the setting block 40 side, that is, the surface on the panel holding frame 20A side when the upper frame 21, lower frame 22, vertical frame 23, 24 side constituting the panel holding frame 20A in the door body 20 is considered the outside and the panel 25 side is considered the inside. In Figures 9 and 10, the outer surface 611 is the lower surface. The inner surface 612 is the surface on the panel 25 side, that is, the inner surface of the panel holding frame 20A, and in Figures 9 and 10, it is the upper surface. Furthermore, the edge where the outer surface 611 and the inclined surface portion 62 intersect is the outer corner portion 6111, and the edge where the inner surface portion 612 and the inclined surface portion 62 intersect is the inner corner portion 6121.

[0023] The longitudinal dimensions of the outer surface 611 and the inner surface 612 are such that the outer surface 611 is slightly longer. Specifically, on the outer surface 611, the longitudinal dimension from one outer corner 6111 to the other outer corner 6111 is longer than the longitudinal dimension from one inner corner 6121 to the other inner corner 6121 on the inner surface 612. As a result, the outer corner 6111 is located outward by a dimension L1 compared to the inner corner 6121. Furthermore, the inclination angle θ of the inclined surface portion 62 relative to the flat plate portion 61 is set to an angle that allows the set plates 60 to be stacked and prevents misalignment between the set plates 60. That is, if the lengthwise dimensions of the flat plate portions 61 are the same, and the inclination angle θ approaches 90°, the set plates 60 will no longer be able to be stacked. On the other hand, if the inclination angle θ approaches 180° and the flat plate portion 61 and the inclined surface portion 62 are arranged in a nearly straight line, when the set plates 60 are stacked, there is a possibility that one set plate 60 will move in the lengthwise direction relative to the other set plate 60 and become misaligned. For this reason, it is preferable to set the inclination angle θ in the range of 130° to 150°. Since the inclined surface portion 62 is inclined from the flat plate portion 61, the thickness dimension T2 of the inclined surface portion 62 is smaller than the thickness dimension T1 of the flat plate portion 61. Furthermore, in this embodiment, when the set plates 60 are stacked, the inclined surfaces 62 do not come into contact with each other, and a small gap is formed. Based on the above conditions, in this embodiment, the longitudinal dimension of the outer surface 611 is set to 64 mm, the longitudinal dimension of the inner surface 612 is set to 63.8 mm, the left and right dimensions L1 are set to 0.1 mm, the thickness dimension T1 of the flat plate portion 61 is set to 1 mm, the thickness dimension T2 of the inclined surface portion 62 is set to 0.7 mm, and the gap dimension L2 between the inclined surface portions 62 is set to 0.06 mm. Note that the specific dimensions of the set plate 60 are not limited to this example and can be set as appropriate based on the above conditions.

[0024] Furthermore, the longitudinal dimension of the outer surface 611 of the flat plate portion 61 is larger than the distance between the pair of side surfaces 415 of the setting block 40. For example, the longitudinal dimension of the outer surface 611 is 64 mm, and the distance between the side surfaces 415 of the setting block 40 is 60 mm. As a result, as shown in Figure 6, when the set plate 60 is placed on top of the surface 411 of the setting block 40, the inclined surface portion 62 is positioned outside the side surfaces 415, so that the inclined surface portion 62 does not interfere with the main body portion 41.

[0025] The two longitudinal sides 613 and 614 of the flat plate portion 61 are inclined to widen outward from the inner surface 612 toward the outer surface 611. As will be described later, the sides 613 and 614 of the flat plate portion 61 become the leading edges when inserting the set plate 60 between the setting block 40 and the panel 25. By making the sides 613 and 614 inclined, insertion can be performed more smoothly compared to when the sides 613 and 614 are perpendicular to the outer surface 611 and inner surface 612. Furthermore, a recess 615 is formed on one of the two sides 613 and 614, side 614. The recess 615 is where the side gate is provided when the set plate 60 is manufactured by injection molding. By providing a side gate in the recess 615, the gate portion can be separated when removing the molded product without having to cut the gate with nippers after injection molding. In this case, even if some resin remains in the gate portion, it will fit inside the recess 615, so it does not cause any problems to leave it as is. Therefore, the manufacturing process can be shortened by eliminating the need for cutting with nippers, and thus manufacturing costs can be reduced. The ends 621 on both sides of the inclined surface portion 62 are inclined such that the width of the inclined surface portion 62 decreases from the base end side, which is continuous with the flat plate portion 61, towards the tip end side. This eliminates the corners that obstruct the flow of resin when filling the mold with synthetic resin material such as polypropylene from the side gate provided in the recess 615, thereby suppressing the occurrence of unfilled areas and improving the molding quality of the set plate 60. Furthermore, since the recess 615 is formed on only one side 614, when inserting the set plate 60 between the setting block 40 and the panel 25, it can be inserted from the side 613 where the recess 615 is not formed, which also allows for smooth insertion of the set plate 60.

[0026] [Panel fastening material] As shown in Figures 5 and 6, each setting block 40 attached to the vertical frames 23 and 24 is fitted with a panel retaining member 80 using anti-theft screws 90. The panel retaining member 80 consists of a stainless steel fixing piece 81 and a cushioning material 85 made of synthetic resin such as ethylene propylene rubber (EPDM) attached to the fixing piece 81. The fixing piece 81 comprises a main body 82 and a locking portion 83. A cushioning material 85 is attached to the main body 82, and an insertion hole 821 is formed therein through which a security screw 90 is inserted. The anti-theft screw 90 is a highly secure screw that cannot be removed with commercially available screwdrivers or wrenches and requires a special tool to install. By screwing this anti-theft screw 90 into the screw hole 416 through the insertion hole 821, the panel retaining material 80 is fixed to the mounting surface 413 of the setting block 40. The locking portion 83 has a hook-shaped tip and is configured to lock onto the locking piece 334 of the engagement groove 33. Although the locking portion 83 is inclined toward the main body portion 41 from the main body portion 82, a recess 417 is formed in the main body portion 41. Therefore, when the panel retaining material 80 is attached to the setting block 40, the locking portion 83 is positioned in the recess 417 and does not interfere with the main body portion 41. As described later, the cushioning material 85 is positioned opposite the panel 25, so that the metal fixing piece 81 does not come into contact with the panel 25 and damage the panel 25.

[0027] [How to install the setting block] Next, the method for attaching the setting block 40 will be explained with reference to Figures 11 to 14. Figures 11 to 14 illustrate the method for attaching the setting block 40 to the lower frame 22. The setting block 40 needs to be positioned by placing its protrusions 43 in the positioning grooves 345 formed in the second visible surface 34 and the second side surface 333. In this case, the worker does not directly attach the protrusions 43 of the setting block 40 to the positioning grooves 345, but rather, as shown in Figures 11 and 12, places the contact plate portion 431 of the protrusions 43 of the setting block 40 against the second visible surface 341 of the second visible surface 34, and places the inner end of the bottom surface 412 of the main body portion 41 against the first visible surface 311, thereby positioning the setting block 40 at an angle to the first visible surface 311. In this case, the hook portion 423 of the claw portion 42 can be positioned slightly away from the locking piece portion 334. Next, the worker moves the setting block 40 by sliding it along the longitudinal direction of the frame body 30 while pressing it against the first and second visible surfaces 311 and 341. At this time, as shown in Figure 12, a part of the bottom surface 412 of the setting block 40 abuts against the first visible surface 311, the contact plate portion 431 of the protruding portion 43 abuts against the second visible surface 341, and the hook portion 423 is not in contact with the locking piece portion 334, so that the setting block 40 can be smoothly slid along the frame body 30.

[0028] As shown in Figures 13 and 14, the setting block 40 is slid while being pressed against the frame body 30, and when the guide portion 433 of the protruding portion 43 moves to the position of the positioning groove 345, the protruding portion 43 is positioned in the positioning groove 345. At this time, since the guide portion 433 of the protruding portion 43 is triangular in side view, when the setting block 40 is slid, the side surface 4331 of the guide portion 433 is guided while contacting the positioning groove 345, so that the guide portion 433 moves to approximately the center of the positioning groove 345, and the setting block 40 can be positioned in the predetermined position. Furthermore, as the setting block 40 is pressed against the frame body 30, the hook portion 423 of the claw portion 42 engages with the locking piece portion 334, the plate portion 432 comes into contact with the first side portion 331, and the bottom surface 412 of the main body portion 41 comes into contact with the first visible surface 311. At this time, the surface of the hook portion 423 on the side of the locking piece portion 334 is inclined, and the surface of the locking piece portion 334 on the side of the hook portion 423 is also inclined. Therefore, when the setting block 40 is pressed against the frame body 30, the inclined surfaces of the hook portion 423 and the locking piece portion 334 come into contact with each other, and the claw portion 42 elastically deforms toward the main body portion 41, allowing the hook portion 423 to smoothly engage with the locking piece portion 334. Here, as shown in Figure 4, the dimension W2 between the hook portion 423 and the plate portion 432 is larger than the dimension W1 between the first side portion 331 and the locking piece portion 334. Therefore, the claw portion 42 elastically deforms toward the first side portion 331, and the stress associated with this elastic deformation is applied toward the locking piece portion 334, biasing the hook portion 423 of the claw portion 42 toward the locking piece portion 334. Also, as the hook portion 423 is biased toward the locking piece portion 334, the plate portion 432 is pressed toward the first side portion 331. As a result, the hook portion 423 of the claw portion 42 and the plate portion 432 of the protruding portion 43 are pressed against the engagement groove portion 33 and fitted, and the setting block 40 is attached to the frame body 30 with a predetermined mounting strength. Using the method described above, the setting blocks 40 are attached to the upper frame 21, lower frame 22, and vertical frames 23 and 24 that constitute the panel holding frame 20A, respectively.

[0029] Next, the panel 25 is assembled into the panel holding frame 20A. This assembly of the panel 25 may be performed at the manufacturing plant of the back door 1 or at the construction site of the back door 1. The setting block 40 is attached to the frame body 30 with a predetermined mounting strength, and the protruding portion 43 is positioned in the positioning groove portion 345, thereby restricting the longitudinal movement of the frame body 30. Furthermore, when the setting block 40 is attached to the frame body 30, the contact surface portion 422 abuts against the second visible surface 341 and the plate portion 432 abuts against the first side portion 331, so that the setting block 40 does not rotate in a direction away from the first visible surface portion 31, starting from the hook portion 423 that engages with the locking piece portion 334. For this reason, the setting block 40 will not come off the frame body 30 even if it is transported to the construction site or moved around in the factory before the panel 25 is assembled. During the installation of panel 25, the outer surface of panel 25 is brought into contact with the surface 411 of the setting block 40 attached to the lower frame 22 and the vertical frame 23 on the hanging side to position it. Next, as shown in Figure 15, set plates 60 are inserted between the setting block 40 attached to the upper edge of the door body 20 and the panel 25 at the top frame 21 and the vertical frame 24 on the door edge side. The required number of set plates 60 are stacked in advance and inserted between the panel 25 and the setting block 40 from the outside in the out-of-plane direction of the door body 20. At this time, one side 613 of the set plate 60 is inserted between the panel 25 and the setting block 40, and it is installed so that the setting block 40 is positioned between the two inclined surfaces 62. Alternatively, the set plates 60 may be inserted one at a time. Next, the panel retaining members 80 are attached to the mounting surfaces 413 of the setting blocks 40 of the vertical frames 23 and 24 using anti-theft screws 90. At this time, the panel retaining members 80 are installed so that the cushioning material 85 of the panel retaining members 80 faces the surface of the panel 25. Next, the trim strip 38 is attached to the trim strip mounting grooves 35 of the upper frame 21, lower frame 22, and vertical frames 23 and 24. With this, the door body 20, in which the panel 25 is held, is completed.

[0030] [Effects of the Embodiment] The setting block 40 can be positioned in the positioning groove 345 formed in the second facing surface 34 by sliding the setting block 40 in the longitudinal direction of the frame body 30 while the setting block 40 has a part of the bottom surface 412 of the main body 41 and the protruding portion 43 in contact with the first facing surface 31 and the second facing surface 34 of the frame body 30. Therefore, the worker can position the protruding portion 43 in the positioning groove 345 by sliding the setting block 40 without having to search for and confirm the positioning groove 345, and the setting block 40 can be easily installed in the correct position, improving the workability of the installation.

[0031] The setting block 40 is mounted with increased strength by elastically deforming the claw portion 42 to engage with the locking piece portion 334 of the engagement groove portion 33 and pressing the plate portion 432 against the first side portion 331. This prevents the setting block 40 from detaching from the panel holding frame 20A and falling during transportation of the door body 20 or during the installation of the panel 25. As a result, the burden on workers installing the panel 25 on the door body 20 at the factory or construction site is reduced, and the ease of installation of the panel 25 is improved. Furthermore, since the mounting strength of the setting block 40 has been increased, there is no need to secure the setting block 40 to the frame body 30 with tape to prevent it from falling. Therefore, there is no need to secure the setting block 40 with tape, nor is there a need to remove the tape from the setting block 40 when assembling the panel 25, which reduces the workload and also reduces the amount of tape that becomes waste after removal.

[0032] Since the setting block 40 is attached by inserting the claw portion 42 and the protruding portion 43 into the engagement groove portion 33 of the frame body 30, the setting block 40 can be attached to any frame body 30 that has an engagement groove portion 33. For this reason, a common setting block 40 can be used for various doors and windows, which can reduce costs.

[0033] Since the claw portion 42 comprises an elastic piece portion 421, a contact surface portion 422, and a hook portion 423, the elastic piece portion 421 of the claw portion 42 can be elastically deformed, allowing the hook portion 423 to be easily engaged with the locking piece portion 334. Furthermore, since the contact surface portion 422 abuts against the second visible surface 341, the setting block 40 can rotate around the engagement portion of the locking piece portion 334 and the hook portion 423, preventing the setting block 40 from coming off. Since the protruding portion 43 has a triangular guide portion 433 in side view, when the setting block 40 is slid, the side portion 4331 can contact the positioning groove portion 345 to guide it, so the setting block 40 can be easily positioned in the predetermined location. In addition, since a gap can be formed between the guide portion 433 and the positioning groove portion 345, rainwater that flows into the engagement groove portion 33 can be drained from the positioning groove portion 345.

[0034] When a portion of the bottom surface 412 of the main body 41 is in contact with the first visible surface 311 and the bottom surface of the protruding portion 43 is in contact with the second visible surface 341, the claw portion 42 is positioned away from the locking piece 334 of the engagement groove portion 33. Therefore, when the setting block 40 is slid, the claw portion 42 does not get caught in the positioning groove portion 345 machined into the second visible surface portion 34, improving the ease of installation and preventing damage to the setting block 40.

[0035] Since the flat plate sections 61 of the set plate 60 can be stacked, one or more set plates 60 can be stacked depending on the gap between the panel 25 and the setting block 40. Therefore, there is no need to prepare multiple types of set plates with different thicknesses, and one type of set plate 60 can be used, thus reducing the manufacturing and management costs of the set plate 60. Furthermore, the operator only needs to check the number of set plates 60 to be stacked and inserted, and does not need to select from multiple types of set plates as appropriate, thus improving the ease of installation of the set plate 60. Furthermore, since the set plate 60 can be easily inserted between the panel 25 and the setting block 40 from the outside in the out-of-plane direction of the door body 20, the ease of installation of the set plate 60 can be improved in this respect as well.

[0036] The set plate 60 has inclined surfaces 62 on both ends of the flat plate portion 61, and the inclined surfaces 62 are positioned with the setting block 40 in between, so that the set plate 60 does not shift relative to the setting block 40. In addition, when multiple set plates 60 are stacked, the inclined surfaces 62 of each set plate 60 are in contact with each other or face each other with a gap between them, so that the set plates 60 do not shift relative to each other. For this reason, when transporting the back door 1 which has a panel holding frame 20A that holds the panel 25, the position of the set plate 60 does not shift, so that the door does not sag.

[0037] Since the set plates 60 are designed so that there is a gap between each inclined surface portion 62 when they are stacked, even if there are dimensional variations in each set plate 60 due to tolerances, etc., the flat plate portions 61 can be brought into contact with each other and stacked securely. Since the sides 613 and 614 of the flat plate portion 61 are inclined surfaces, the set plate 60 can be easily inserted between the panel 25 and the setting block 40.

[0038] [Differentiation] However, the present invention is not limited to the configurations of the embodiments described above. For example, the fixture to which the setting block 40 is attached is not limited to the back door 1, but may also be various types of doors such as front doors, or various types of windows such as sliding windows, casement windows, and fixed windows, and the setting block 40 can be used with various types of fixtures. Furthermore, in the above embodiment, the support projection 32 of the frame body 30 was positioned on the indoor side of the panel 25 and the trim 38 was positioned on the outdoor side of the panel 25. However, it is also possible for the trim 38 to be positioned on the indoor side of the panel 25 and the support projection 32 to be positioned on the outdoor side of the panel 25.

[0039] In the above embodiment, the setting block 40 was attached to the frame body 30 by engaging the claw portion 42 with the locking piece portion 334 and bringing the plate portion 432 into contact with the first side portion 331. However, for example, the setting block 40 may also be attached to the frame body 30 by having the claw portion 42 engage with the locking piece portion 334 while the plate portion 432 is omitted, and bringing the interior surface 414 of the main body portion 41 into contact with and engaging with the support projection portion 32.

[0040] The configuration of the claw portion 42 and the protruding portion 43 is not limited to the above embodiment. For example, the claw portion 42 may be configured without a contact surface portion 422. Also, the guide portion 433 of the protruding portion 43 is not limited to a triangular shape in side view, but may be trapezoidal, as long as it can be positioned in the positioning groove portion 345.

[0041] The set plate 60 may be configured such that the longitudinal dimensions of the outer surface 611 and inner surface 612 of the flat plate portion 61 are the same, and the inclined surfaces 62 come into contact with each other when the set plates 60 are stacked. Alternatively, the side surfaces 613 and 614 of the flat plate portion 61 may be surfaces perpendicular to the outer surface 611 and inner surface 612, rather than inclined surfaces.

[0042] [summary] The setting block of the present invention is a setting block that is attached to a panel holding frame that holds a panel, comprising a first visible surface portion, an engagement groove portion formed continuously with the first visible surface portion and along the longitudinal direction of the first visible surface portion, a second visible surface portion provided on either side of the engagement groove portion on the first visible surface portion, and a positioning groove portion formed at a predetermined location in the longitudinal direction of the second visible surface portion, and comprises a main body portion having a bottom surface that can abut against the first visible surface portion, a claw portion extending from the main body portion and configured to engage with the engagement groove portion, and a projection portion extending from the main body portion and protruding beyond the bottom surface and positioned in the positioning groove portion, wherein when a part of the bottom surface of the main body portion abuts against the first visible surface portion and the projection portion abuts against the second visible surface portion, it is movable along the panel holding frame, and when the projection portion is positioned in the positioning groove portion, the bottom surface of the main body portion abuts against the first visible surface portion and the claw portion engages with the engagement groove portion. According to the present invention, by sliding the setting block with a part of the bottom surface of the main body and the protruding portion in contact with the first and second visible surfaces of the panel holding frame, the protruding portion can be positioned in the positioning groove formed in the second visible surface. Therefore, the operator does not need to search for and confirm the positioning groove; they can position the protruding portion in the positioning groove by sliding the setting block, making it easy to install the setting block in the correct position and improving installation workability.

[0043] In the setting block of the present invention, the engagement groove portion comprises a first side portion continuous with the first visible surface portion, a bottom portion continuous with the first side portion, and a second side portion continuous with the bottom portion, wherein the second side portion has a locking piece portion projecting toward the first side portion, and the projecting portion has a plate portion that abuts toward the first side portion, and when the claw portion is engaged with the engagement groove portion, the claw portion elastically deforms so that the plate portion presses against the first side portion and the claw portion presses against the locking piece portion. According to the present invention, since the claw portion is elastically deformed, the plate portion can be pressed against the first side surface and the claw portion can be pressed against the locking piece, thereby improving the mounting strength of the setting block. As a result, it is possible to prevent the setting block from detaching from the panel holding frame and falling, reducing the burden on the worker and improving the workability of panel installation. In addition, there is no need to fix the setting block with tape to prevent it from falling, which also reduces the workload and reduces the amount of tape that becomes waste when removed. Furthermore, since the setting block is attached by pressing the claw portion and plate portion against the engagement groove portion of the panel holding frame, it can be attached to various panel holding frames that have an engagement groove portion.

[0044] In the setting block of the present invention, it is preferable that the claw portion comprises an elastic piece portion extending from the main body portion, a contact surface portion extending from the elastic piece portion and contacting the second visible surface portion, and a hook portion extending from the contact surface portion and engaging with the locking piece portion. According to the present invention, the elastic piece of the claw can be elastically deformed, allowing the hook to be easily engaged with the locking piece. Furthermore, since the contact surface contacts the second visible surface, the setting block can rotate around the engagement portion of the locking piece and the hook, preventing the setting block from coming off.

[0045] In the setting block of the present invention, it is preferable that the protruding portion includes a guide portion whose side surface facing the positioning groove portion is inclined in a direction that brings them closer together from the opening side to the bottom side of the positioning groove portion. According to the present invention, when the setting block is slid, the side surface of the guide portion can be brought into contact with the positioning groove portion to guide it, so that the setting block can be easily positioned in a predetermined location. Furthermore, since a gap can be formed between the guide portion and the positioning groove portion, rainwater that flows into the engagement groove portion can be drained from the positioning groove portion.

[0046] In the setting block of the present invention, it is preferable that the claw portion is positioned away from the engagement groove portion when a part of the bottom surface of the main body portion is in contact with the first visible surface portion and the protruding portion is in contact with the second visible surface portion. According to the present invention, when the setting block is slid, the claw portion does not get caught in the positioning groove processed on the second visible surface, thereby improving the ease of installation and preventing damage to the setting block.
