Description

[Technical Field]

[0001] The present invention relates to a hinge mounting structure that supports a shoji screen on a frame so that it can be opened and closed freely. [Background technology]

[0002] The hinges that support the shoji screens must be installed to accommodate construction errors in the frame to which they are attached, so they are installed so that their position can be adjusted. For example, a back plate is fixed to the outer periphery of the projection piece of the vertical frame with a shoulder screw and a positioning screw, one of the slats that make up the hinge is abutted against the inner periphery of the projection piece, and a screw inserted into a long hole in the projection piece is threaded into the back plate to attach the hinge to the vertical frame (see, for example, Patent Document 1). The shoulder screw that attaches the back plate is inserted into a long hole in the projection piece, and the position of the hinge can be adjusted by removing the positioning screw and loosening the screw that secures the slat to the back plate.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A hinge mounting structure according to an embodiment of the present invention will now be described with reference to the drawings. As an example of the hinge mounting structure according to this embodiment, we will explain an example in which the mounting structure of a hinge 3 that supports a shoji screen 4 so that it can be opened and closed freely on a frame 2 fixed to the building structure as shown in Figure 1 is used in a bathroom fixture 1 as shown in Figure 2.

[0010] Figure 2 shows bathroom fitting 1 as seen from the dressing room side, with frame body 2 being a rectangular framework made up of a pair of vertical frames 20 spaced apart in the left-right direction and a pair of horizontal frames 21 respectively positioned between the upper and lower ends of the pair of vertical frames 20. A vertical frame 22 is provided approximately in the center of the pair of horizontal frames 21, and a face plate 23 is fitted to the right side of vertical frame 22 to form a wall, with a shoji screen 4 provided to the left of vertical frame 22 so that it can be opened and closed. Each of vertical frames 20, horizontal frames 21, and vertical frame 22 is an extruded member with its longitudinal direction as the extrusion direction.

[0011] As shown in Figure 3, the shoji screen 4 is attached to the left vertical frame 20 via hinges 3. The left vertical frame 20 has a vertical frame projection wall portion 20a that is plate-shaped and forms a projection surface facing the inside of the frame body 2, a facing wall portion 20b that faces the left side of the vertical frame projection wall portion 20a with a gap between them, a bathroom-side connecting wall portion 20c that connects the bathroom-side ends of the vertical frame projection wall portion 20a and the facing wall portion 20b, and a central connecting wall portion 20d that extends leftward from approximately the center in the projection direction of the vertical frame projection wall portion 20a and connects to the end of the facing wall portion 20b on the changing room side, and has a hollow portion 20e that has a rectangular shape in horizontal cross section that is long in the projection direction and penetrates in the vertical direction.

[0012] The vertical frame projection wall portion 20a extends further toward the dressing room side than the central connecting wall portion 20d, and at the end of the vertical frame projection wall portion 20a on the dressing room side, it has an inner peripheral extension piece 20f that extends toward the inner periphery of the frame body 2 to form a sighting surface, and an outer peripheral extension piece 20g that extends toward the outer periphery of the frame body 2 to form a sighting surface. Also, on the inner periphery of the frame body 2, there is provided an inner peripheral facing piece 20h that extends toward the inner periphery from the vertical frame projection wall portion 20a and faces the inner periphery extending piece 20f with a gap on the bathroom side, and an outer peripheral facing piece 20i that extends toward the outer periphery from the vertical frame projection wall portion 20a and faces the outer periphery extending piece 20g with a gap on the bathroom side.

[0013] A water-stopping member 5 is provided at the tip of the inner peripheral facing piece 20h, which abuts against the shoji screen 4 when it is closed on the bathroom side. A cover member 7 is fitted between the inner peripheral extension piece 20f and the inner peripheral facing piece 20h, and is configured to cover the screws 8 that enter the vertical frame projection wall portion 20a between the inner peripheral extension piece 20f and the inner peripheral facing piece 20h from the inner peripheral side and secure the vertical frame 20 to the frame.

[0014] As shown in Figure 1, the longitudinal ends of the horizontal frame 21 are abutted against and joined to the vertical frame projection wall portion 20a of the vertical frame 20. The horizontal frame 21 has a horizontal frame projection wall portion 21a that forms a projection surface and is substantially plate-shaped, and screws that pass through the vertical frame projection wall portion 20a from the outer periphery of the frame body 2 are screwed into threaded portions 21b that are formed along the longitudinal direction on the outer periphery of the horizontal frame projection wall portion 21a, joining the vertical frame 20 and the horizontal frame 21. Then, a shoji screen 4 is arranged inside the frame body 2 formed by the vertical frame projection wall portion 20a and the horizontal frame projection wall portion 21a.

[0015] As shown in Figure 1, the hinge 3 in this embodiment is a so-called pivot hinge in which a shoji-side hinge member 30 attached to the upper and lower ends of the shoji 4 and a frame-side hinge member 31 attached to the frame 2 are rotatably engaged by a pin 32. The shoji-side hinge member 30 is screwed to the upper surface 40a of the upper frame 40 of the shoji 4, and as shown in Figure 4, has a pin insertion hole 30b that penetrates vertically and through which a pin 32 is inserted.

[0016] As shown in Figures 3 and 4, the frame-side hinge member 31 of the first embodiment is attached by clamping the vertical frame projection wall portion 20a between the frame-side hinge member 31 and the back plate 9 when a fixing screw 10 is screwed into a back plate 9 provided on the outer periphery of the vertical frame projection wall portion 20a and tightened. For this reason, the vertical frame projection wall portion 20a of the vertical frame 20 has a fixing screw 10 inserted therethrough and a fixing screw insertion elongated hole 20j that is long in the projection direction. In the first embodiment, the fixing screw insertion elongated hole 20j corresponds to the second elongated hole.

[0017] The frame body side hinge member 31 has a hinge main body 31b provided with a frame hinge side insertion hole 31a through which the pin 32 is inserted, and a frame body abutment portion 31c extending from the hinge main body 31b toward the dressing room side and abutting against the vertical frame projection wall portion 20a of the vertical frame 20. The frame body abutment portion 31c is substantially plate-shaped and is arranged on the outer periphery of the hinge main body 31b, and the hinge main body 31b and the frame body abutment portion 31c have a flat frame body abutment surface 31d that faces the vertical frame projection wall portion 20a. In addition, the frame body abutment portion 31c has a fixing screw insertion hole 31e through which a fixing screw 10 is inserted to attach the frame body side hinge member 31 to the vertical frame 20.

[0018] The back panel 9 has a flat back panel main body 9a that abuts against the outer peripheral surface of the vertical frame recessed wall portion 20a, and a back panel extension piece 9b that extends outward from the bathroom-side end of the back panel main body 9a. Near the upper end of the back panel main body 9a, a shoulder screw insertion hole 9c is provided through which a shoulder screw 11 is inserted to attach the back panel main body 9a to the upper end of the vertical frame recessed wall portion 20a. The shoulder screw insertion hole 9c has a vertical width slightly wider than the diameter of the shoulder portion 11a of the shoulder screw 11 and is an elongated hole that is elongated in the recessed direction. The length L1 of the shoulder portion 11a of the shoulder screw 11 is slightly longer than the thickness t1 of the back panel 9. In other words, when the shoulder screw 11 is tightened, the distance L1 between the head 11b of the shoulder screw 11 and the outer peripheral surface of the vertical frame recessed wall portion 20a is slightly wider than the thickness t1 of the back panel 9. In the first embodiment, the stepped screw insertion hole 9c corresponds to the first elongated hole.

[0019] For this reason, even when the stepped screw 11 is inserted through the stepped screw insertion hole 9c and screwed into the threaded hole 20k of the vertical frame recessed wall portion 20a and tightened, the back plate 9 is not fixed by the stepped screw 11 and can move in the recessed direction within the length of the stepped screw insertion hole 9c. Here, the stepped screw 11 corresponds to a holding screw that holds the back plate 9 in a state where the distance between the head 11b and the vertical frame recessed wall portion 20a is wider than the thickness of the back plate 9 in which the stepped screw insertion hole 9c as the first elongated hole is provided.

[0020] With the back plate 9 attached with shoulder screws 11, the bathroom-side portion is positioned within the hollow portion 20e of the vertical frame 20. For this reason, a notch 20l is provided in the central connecting wall portion 20d of the vertical frame 20 so that the back plate 9 can be positioned both inside and outside the hollow portion 20e, as shown in Figure 5. In addition, the back plate extension piece 9b of the back plate 9 is positioned within the hollow portion 20e, and the tip of the back plate extension piece 9b faces the opposing wall portion 20b of the vertical frame 20 with a slight gap between them, for example, a gap that prevents contact when no external force is applied.

[0021] Below the stepped screw insertion hole 9c in the back panel main body 9a, there is provided a fixing screw threading hole 9d into which the fixing screw 10 inserted through the fixing screw insertion hole 31e of the frame-side hinge member 31 and the fixing screw insertion elongated hole 20j of the vertical frame projection wall portion 20a is threaded. The fixing screw threading hole 9d is positioned so that the fixing screw 10 can be threaded into the fixing screw threading hole 9d when the frame is attached to the vertical frame projection wall portion 20a with the stepped screw 11. Therefore, as shown in FIG. 6 , the position in the vertical frame projection wall portion 20a where the stepped screw 11 is threaded and the position where the fixing screw 10 is inserted are spaced apart in the vertical direction and are separated by the horizontal frame projection wall portion 21a of the upper horizontal frame 21 joined to the vertical frame 20. In other words, the fixing screw 10 that secures the frame-side hinge member 31 is located on the inner periphery of the frame body 2, and the stepped screw 11 that attaches the back panel 9 is located on the outer periphery of the frame body 2. In the first embodiment, the horizontal frame 21 is located on the inner periphery of the projection surface and corresponds to a partition section that separates the portion of the projection wall where the shoulder screw is inserted from the portion where the fixing screw is inserted.

[0022] The frame body side hinge member 31 is abutted against the inner peripheral surface of the vertical frame projection wall portion 20a when the back plate 9 is attached to the vertical frame projection wall portion 20a by a shoulder screw 11 so that it can be moved in the projection direction, and is attached to the vertical frame projection wall portion 20a by inserting a fixing screw 10 through the fixing screw insertion hole 31e and the fixing screw insertion long hole 20j and screwing it into the fixing screw threading hole 9d of the back plate 9 and tightening it.

[0023] At this time, when the fixing screw 10 inserted through the fixing screw insertion hole 31e and the fixing screw insertion elongated hole 20j is screwed into the fixing screw threading hole 9d of the back plate 9, the back plate 9 is pressed in the direction away from the vertical frame projected wall portion 20a by the fixing screw 10, but the tip of the back plate extension piece 9b abuts against the facing wall portion 20b of the vertical frame 20, thereby restricting movement of the back plate 9 in the direction away from the vertical frame projected wall portion 20a. Here, the back plate extension piece 9b of the back plate 9 and the facing wall portion 20b of the vertical frame 20 engage with each other and correspond to a restricting portion that restricts movement of the back plate in the direction away from the projected wall portion.

[0024] In addition, the back plate 9 can be moved in the projection direction together with the frame-side hinge member 31 by loosening the fixing screws 10. Therefore, by loosening the fixing screws 10, it is possible to adjust the position of the frame-side hinge member 31 in the projection direction.

[0025] According to the mounting structure of the hinge 3 of the first embodiment, the back plate 9 has a stepped screw 11 having a step 11a longer than the thickness t1 of the back plate 9 inserted into the stepped screw insertion hole 9c of the back plate main body 9a, and is screwed into the frame body projecting wall portion 20a, and a fixing screw 10 which is inserted into the fixing screw insertion long hole 20j of the frame body projecting wall portion 20a and fixes the frame body side hinge member 31 is tightened into the back plate 9, clamping and fixing the frame body projecting wall portion 20a between the back plate 9 and the frame body side hinge member 31.

[0026] Therefore, by loosening the fixing screws 10, the frame-side hinge member 31 can be moved together with the back plate 9 in the projection direction within the range of the stepped screw insertion holes 9c and the elongated fixing screw insertion holes 20j. With this configuration, the position of the frame-side hinge member 31 in the projection direction can be adjusted simply by loosening the fixing screws 10 that secure the frame-side hinge member 31 from the inner periphery of the frame 2. At this time, even if the fixing screws 10 are accidentally removed, the back plate 9 is held in a movable state by the stepped screws 11 to the frame projection wall portion 20a. Therefore, the back plate 9 will not accidentally fall off, resulting in excellent workability.

[0027] Furthermore, the portion of the frame body recessed wall portion 20a through which the shoulder screws 11 are inserted and the portion through which the fixing screws 10 are inserted are separated by the upper horizontal frame 21, whose ends abut against the frame body recessed wall portion 20a and are joined to the vertical frame 20, so the shoulder screws 11 are concealed by the horizontal frame 21 and are not visible from the inner peripheral side of the frame body 2. For this reason, the number of visible screws is small, resulting in excellent design. In the first embodiment, an example was described in which the frame body side hinge member 31 is attached to the vertical frame 20 and the shoulder screws 11 are concealed by the horizontal frame, but this is not limiting, and a configuration in which a hinge is attached to the horizontal frame and the shoulder screws are concealed by the vertical frame is also acceptable, for example.

[0028] Furthermore, before the frame-side hinge member 31 is fixed by the fixing screws 10, the back plate 9 is movably attached to the frame-side wall portion 20a only by the shoulder screws 11, so when the fixing screws 10 are screwed into the fixing screw threading holes 9d of the back plate 9, the fixing screws 10 press the back plate 9 outward. At this time, in the hinge mounting structure of the first embodiment, the back plate extension piece 9b of the back plate 9 abuts against the facing wall portion 20b of the vertical frame 20, so movement of the back plate 9 in the direction away from the frame-side wall portion 20a is restricted. This makes it possible to easily screw the fixing screws 10 into the back plate 9.

[0029] More specifically, the hinge 3, which needs to be adjusted in its position in the projection direction at the construction site, is attached by inserting the shoulder screw 11 into the shoulder screw insertion hole 9c of the back plate 9 and screwing it into the frame projection wall portion 20a, so that the hinge 3 can move together with the back plate 9 when the fixing screw 10 that fixes the frame side hinge member 31 is loosened. Therefore, even when the shoulder screw 11 is tightened, the back plate 9 is not fixed.

[0030] In addition to the fixing screws 10 that fix the frame-side hinge member 31 and the back plate 9, shoulder screws 11 are also used to movably attach the back plate 9, which results in a large number of screws, and since it would be unsightly to the design if all of the screws were visible, the shoulder screws 11 are positioned only on the outer periphery of the frame-side wall portion 20a, relative to the abutment position of the horizontal frame 21. In other words, only the upper end of the back plate 9, which is distant from the position of the fixing screws 10 that fix the frame-side hinge member 31, is attached loosely by the shoulder screws 11.

[0031] For this reason, when the fixing screw 10 is screwed into the back plate, the back plate extension piece 9b of the back plate 9 pressed by the fixing screw 10 comes into contact with the facing wall portion 20b of the vertical frame 20. Therefore, even if the back plate 9 is attached loosely to the frame body front wall portion 20a, it will not move in the direction away from the frame body front wall portion 20a, so it will be possible to easily screw the fixing screw 10 into the back plate 9. This provides excellent workability.

[0032] Next, a description will be given of a hinge mounting structure of the second embodiment. The hinge mounting structure of the second embodiment differs from that of the first embodiment in the mounting structure of the frame body side hinge member 31. In the second embodiment, the back plate 12 for attaching the frame-side hinge member 31 is formed long in the projection direction. As shown in Figures 7 to 9, the back plate 12 in the second embodiment is arranged on the outer periphery of the frame-side projection wall portion 20a, extending from the hollow portion 20e to the changing room side beyond the outer periphery facing piece 20i. For this reason, the central connecting wall portion 20d and the outer periphery facing piece 20i that form the hollow portion 20e are cut out at the location where the back plate 12 is to be placed.

[0033] The back plate 12 has a flat back plate main body 12a that abuts against the outer peripheral surface of the vertical frame projection wall portion 20a, and a back plate extension piece 12b that extends outward from the bathroom-side end of the back plate main body 12a. A stepped screw engagement portion 12c is provided near the dressing room-side end of the back plate main body 12a, into which a stepped screw 11 that penetrates the vertical frame projection wall portion 20a from the inner peripheral side is screwed in order to attach the back plate main body 12a to the vertical frame projection wall portion 20a. The vertical frame projection wall portion 20a has a stepped screw insertion elongated hole 20m that is elongated in the projection direction and into which the stepped screw 11 is inserted.

[0034] The elongated stepped screw insertion hole 20m is provided between the inner peripheral extension piece 20f and the inner peripheral opposing piece 20h of the vertical frame recessed wall portion 20a. The elongated stepped screw insertion hole 20m also has a vertical width slightly wider than the diameter of the step portion 11a of the stepped screw 11, and is a long hole that is long in the recessed direction. The length L2 of the step portion 11a of the stepped screw 11 is formed slightly longer than the thickness t2 of the back plate 12. In the second embodiment, the elongated stepped screw insertion hole 20m corresponds to the first elongated hole.

[0035] Therefore, even when shoulder screws 11 are inserted from the inner periphery into elongated shoulder screw insertion holes 20m and screwed into stepped screw engagement portions 12c of back plate 12, back plate 12 can move in the forward direction within the range of the length of elongated shoulder screw insertion holes 20m. When back plate 12 is attached with shoulder screws 11, its lower end is supported by the notch in inner periphery extension piece 20f or inner periphery facing piece 20h, and it is positioned approximately horizontally. Back plate extension piece 12b on the bathroom side is positioned within hollow portion 20e, and the tip of back plate extension piece 12b faces facing wall portion 20b of vertical frame 20 with a slight gap between them, for example, a gap large enough to prevent contact when no external force is applied.

[0036] On the bathroom side of the stepped screw engagement portion 12c of the back panel main body portion 12a, there is provided a fixing screw engagement hole 12d into which a fixing screw 10 inserted through the fixing screw insertion hole 31e of the frame body side hinge member 31 and the fixing screw insertion elongated hole 20j, which serves as a second elongated hole, of the vertical frame projection wall portion 20a is threaded. The fixing screw engagement hole 12d is positioned so that the fixing screw 10 can be threaded into it when the vertical frame projection wall portion 20a is attached with the stepped screw 11. For this reason, the position in the vertical frame projection wall portion 20a where the stepped screw 11 is inserted and the position where the fixing screw 10 is inserted are spaced apart in the projection direction and are separated by an inner peripheral opposing piece 20h provided on the vertical frame 20. That is, the fixing screws 10 that fix the frame-side hinge members 31 are located on the bathroom side of the inner peripheral facing piece 20h in the vertical frame projection wall portion 20a, and the shoulder screws 11 that attach the back panel 12 are located on the undressing room side of the inner peripheral facing piece 20h. In the second embodiment, the inner peripheral facing piece 20h is located on the inner peripheral side of the projection surface and corresponds to a partition that separates the area in the projection wall portion where the shoulder screws are inserted from the area where the fixing screws are inserted.

[0037] Then, with the back plate 12 attached to the vertical frame projection wall portion 20a by the shoulder screws 11 so as to be movable in the projection direction, the frame body-side hinge member 31 abuts against the projection surface on the inner periphery of the vertical frame projection wall portion 20a, and is attached to the vertical frame projection wall portion 20a by inserting fixing screws 10 through the fixing screw insertion holes 31e and the fixing screw insertion elongated holes 20j and screwing them into the fixing screw threading holes 12d of the back plate 12 and tightening them. At this time, when the fixing screws 10 inserted through the fixing screw insertion holes 31e and the fixing screw insertion elongated holes 20j are screwed into the fixing screw threading holes 12d of the back plate 12, the back plate 12 is pressed in a direction away from the vertical frame projection wall portion 20a by the fixing screws 10, but the tip of the back plate extension piece 12b abuts against the facing wall portion 20b of the vertical frame 20, restricting movement of the back plate 12 in a direction away from the vertical frame projection wall portion 20a. In the second embodiment, the back plate extension piece 12b of the back plate 12 and the facing wall portion 20b of the vertical frame 20 engage with each other and correspond to a restricting portion that restricts movement of the back plate in a direction away from the projecting wall portion.

[0038] In addition, the back plate 12 can be moved in the projection direction together with the frame-side hinge member 31 by loosening the fixing screws 10. Therefore, by loosening the fixing screws 10, it is possible to adjust the position of the frame-side hinge member 31 in the projection direction.

[0039] According to the mounting structure of the hinge 3 of the second embodiment, the back plate 12 is fixed by clamping the frame body front wall portion 20a between the back plate 12 and the frame body side hinge member 31, with the shoulder screws 11 inserted into the long shoulder screw insertion holes 20m being screwed into the shoulder screw engagement portions 12c and the fixing screws 10 inserted into the long fixing screw insertion holes 20j being tightened into the back plate 12. Therefore, by loosening the fixing screws 10, the frame body side hinge member 31 can be moved together with the back plate 12 in the front direction within the range of the long shoulder screw insertion holes 20m and the long fixing screw insertion holes 20j.

[0040] With this configuration, the position of the frame-side hinge member 31 in the projection direction can be adjusted simply by loosening the fixing screw 10 that fixes the frame-side hinge member 31 from the inner periphery of the frame 2. Even if the fixing screw 10 is accidentally removed, the back plate 12 is held in a movable state on the frame-side projection wall 20a by the shoulder screw 11 and the notch in the inner periphery extension piece 20f or the inner periphery facing piece 20h. This prevents the back plate 12 from accidentally falling off, resulting in excellent workability.

[0041] Furthermore, since the portion of the frame body recessed wall portion 20a through which the shoulder screws 11 are inserted and the portion through which the fixing screws 10 are inserted are separated by an inner peripheral facing piece 20h provided on the frame body recessed wall portion 20a, the inner peripheral facing piece 20h makes it difficult to see the shoulder screws 11. As a result, the number of screws that are visible is reduced, resulting in excellent design. Furthermore, in the second embodiment, cover members 7 that conceal the screws 8 that secure the vertical frame 20 to the frame frame are attached to the inner peripheral extension pieces 20f and the inner peripheral facing pieces 20h provided on both sides in the recessed direction of the shoulder screw insertion slots 20m through which the shoulder screws 11 are inserted. This ensures that the shoulder screws 11 are concealed, further improving design.

[0042] Furthermore, before the frame body side hinge member 31 is fixed by the fixing screw 10, the back plate 12 is placed on the notch of the inner peripheral extension piece 20f or the inner peripheral opposing piece 20h, and is movably attached to the frame body front wall portion 20a by only the shoulder screw 11. Even if the fixing screw 10 presses the back plate 12 toward the outer periphery, the back plate extension piece 12b of the back plate 12 abuts against the opposing wall portion 20b of the vertical frame 20, so that movement of the back plate 12 away from the frame body front wall portion 20a is restricted, and the fixing screw 10 can be easily screwed into the back plate 12.

[0043] In the above embodiment, an example has been described in which shoulder screw 11 is used as a holding screw, but this is not limiting. For example, a screw having a collar inserted therethrough that has a length equivalent to the shoulder of the shoulder screw may be used, as long as it is inserted into the first elongated hole and screwed into the other of the recessed wall portion and the back plate, and can hold the back plate in a state in which the distance between the head of the screw and the other of the recessed wall portion and the back plate is wider than the thickness of the portion in which the first elongated hole is provided.

[0044] In the above embodiment, a pivot hinge has been described as an example, but the present invention is not limited to this, and any hinge that rotatably attaches a shoji screen, including a door body, to a frame, such as a flat hinge, may be used. Also, in the above embodiment, an example has been described in which the hinge mounting structure of the present invention is applied to a bathroom fixture, but the applicable fixture is not limited to bathroom fixtures, and may be any fixture in which a shoji screen is attached to a frame via a hinge.

[0045] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. The present embodiment includes at least the following aspects of the invention.

[0046] Aspect 1: A hinge mounting structure in which a shoji screen is supported on a frame body so as to be able to be opened and closed freely, and a hinge that abuts from the inner periphery of the frame body to a projection wall portion that forms a projection surface in the frame body is mounted together with a back plate that is arranged on the outer periphery of the projection wall portion by a fixing screw, wherein one of the projection wall portion and the back plate has a first elongated hole along the projection direction, and the projection wall portion has a second elongated hole along the projection direction, and a holding screw that is inserted into the first elongated hole and holds the back plate is attached to one of the projection wall portion and the back plate. The back plate is held in a state in which the distance between the head of the retaining screw and the other of the projected wall portion and the back plate is wider than the thickness of the portion where the first long hole is provided, and the fixing screw inserted into the second long hole is tightened into the back plate to clamp and fix the projected wall portion between the hinge and the retaining screw, and the projected wall portion is separated by a partition portion into the portion where the retaining screw is inserted and the portion where the fixing screw is inserted.This is a hinge mounting structure characterized by the above.

[0047] According to the hinge mounting structure of the first aspect, the back plate is held in place by a retaining screw inserted through the first elongated hole and threaded into the other of the recessed wall portion and the back plate, with the distance between the head of the retaining screw and the other of the recessed wall portion and the back plate being wider than the thickness of the portion where the first elongated hole is provided. A fixing screw inserted through the second elongated hole of the recessed wall portion is fastened to the back plate, clamping the recessed wall portion between the retaining screw and the hinge. Therefore, the back plate is not fixed by the retaining screw. By loosening the fixing screw, the hinge and the back plate can be moved in the recessed direction within the range of the first and second elongated holes. Therefore, the position of the hinge in the recessed direction can be adjusted simply by loosening the fixing screw that secures the hinge from the inner periphery of the frame. Even if the fixing screw is accidentally removed, the back plate is still held in place by the retaining screw in a movable state on the recessed wall portion. This prevents the back plate from accidentally falling off, resulting in excellent workability.

[0048] In addition, the area of ​​the visible wall where the shoulder screws are inserted and the area where the fixing screws are inserted are separated by a partition located on the inner periphery of the visible surface, so the retaining screws are hidden by the partition and are difficult to see. As a result, the number of visible screws is reduced, resulting in excellent design.

[0049] Aspect 2: A hinge mounting structure as described in Aspect 1, characterized in that the frame body is formed by joining a vertical frame and a horizontal frame, the hinge is fixed to one of the vertical frame and the horizontal frame, and the partition portion is the other of the vertical frame and the horizontal frame.

[0050] According to the hinge mounting structure of aspect 2, the area where the fixing screw is inserted in one of the vertical and horizontal frames to which the hinge is fixed is separated from the area where the retaining screw that movably holds the back plate is inserted by the other of the vertical and horizontal frames, so the retaining screw is not visible at all from the inner periphery of the frame body to which the hinge is attached. Therefore, the number of visible screws is reduced, resulting in excellent design.

[0051] Aspect 3: A hinge mounting structure according to Aspect 1, characterized in that the partition portion is a portion provided on the frame body and protrudes inward from the visible surface to form a visible surface.

[0052] According to the hinge mounting structure of aspect 3, the area where the fixing screw is inserted in one of the vertical and horizontal frames to which the hinge is fixed is separated by an area where the retaining screw that movably holds the back plate is inserted and an area that is provided on the frame body and protrudes inward from the visible surface to form the visible surface, so the retaining screw is difficult to see from the inner periphery side of the frame body to which the hinge is attached. Therefore, the number of easily visible screws is small, resulting in excellent design.

[0053] Aspect 4: The hinge mounting structure according to Aspect 3, further comprising a cover member that is engaged with the partition portion and covers the retaining screw.

[0054] According to the hinge mounting structure of aspect 4, even if the portion of one of the vertical and horizontal frames to which the hinge is fixed, through which the fixing screw is inserted, and the portion through which the shoulder screw for attaching the back plate is inserted, are separated by a portion provided on the frame body that protrudes inward from the visible surface to form a visible surface, the retaining screw is concealed by the cover member that engages with the partition. Therefore, the retaining screw that movably holds the back plate by the cover member is completely invisible, resulting in excellent design.

[0055] Aspect 5: A hinge mounting structure according to any one of aspects 1 to 4, characterized in that the frame body and the back plate are provided with a regulating portion that engages with each other and regulates movement of the back plate in a direction away from the projecting wall portion.

[0056] If the back plate is movably held in the recessed wall portion by only a retaining screw at a position separated from the portion where the hinge's fixing screw is inserted, the fixing screw presses the back plate toward the outer periphery when the fixing screw is screwed into the back plate, causing it to move away from the recessed wall portion, making it difficult to screw the fixing screw into the back plate. According to the hinge mounting structure of the fifth aspect, the frame and back plate are provided with a restricting portion, which restricts the back plate from moving away from the recessed wall portion. This makes it possible to easily screw the fixing screw into the back plate. This results in excellent workability. [Explanation of symbols]
