Summary of the Invention
Problems to be Solved by the Invention
[0004] The present inventors considered attaching a handle to the door body via a pedestal in such a fixture. In this case, the pedestal and the handle are arranged side by side in the thickness direction of the door body. Therefore, the side surface of the pedestal and the side surface of the handle are arranged side by side in the thickness direction of the door body.
[0005] However, the present inventors focused on the following problems. That is, when the relative position between the side surface of the pedestal and the side surface of the handle is displaced in the width direction of the door body due to dimensional errors or the like of the fixture, the displacement is likely to be noticeable. As a result, the design property of the fixture deteriorates.
[0006] In the above, the problems have been described by taking the case where the relative position between the side surface of the pedestal and the side surface of the handle is displaced in the width direction of the door body as an example, but the same problems can also occur in other combinations than the combination of the side surface of the pedestal and the side surface of the handle.
[0007] This disclosure is made in view of the above circumstances, and aims to make the deviation less noticeable even when the relative positions of the first end face and the second end face, which are aligned in a predetermined direction, deviate from their original relative positions. [Means for solving the problem]

Mode for Carrying Out the Invention
[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to the following embodiments, and can be appropriately modified and implemented without departing from the spirit of the present disclosure.
[0011] [First Embodiment] As shown in Figure 1, the joinery 100 comprises a door frame 10 and a door body 20. Hereafter, as shown in Figure 2, two directions that are orthogonal to each other in the horizontal plane will be referred to as the "X direction" and the "Y direction". Furthermore, below, one side in the X direction will be referred to as the "X- side" and the opposite side as the "X+ side". Similarly, one side in the Y direction will be referred to as the "Y- side" and the opposite side as the "Y+ side".
[0012] As shown in Figure 1, the door frame 10 comprises a vertical frame 11 on the X-side, an upper frame 12, a vertical frame 13 on the X+ side, and a lower frame 14. The two vertical frames 11 and 13 are spaced apart in the X direction and arranged side by side. Each vertical frame 11 and 13 extends in the vertical direction. The upper frame 12 and the lower frame 14 each extend in the X direction. The upper frame 12 connects the upper ends of the two vertical frames 11 and 13. The lower frame 14 connects the lower ends of the two vertical frames 11 and 13.
[0013] The door body 20 is installed inside the door frame 10. Specifically, one long side of the door body 20 is attached to the vertical frame 13 on the X+ side via hinges or the like, so as to be rotatable on an axis in the vertical direction. The following description will focus on the joinery 100 as seen when the door body 20 is closed.
[0014] As shown in Figure 2, an interior handle 40B, extending vertically, is attached to the interior surface of the door body 20 via two upper and lower bases 30. Similarly, an exterior handle 40A, extending vertically, is attached to the exterior surface of the door body 20 via two upper and lower bases 30. In this embodiment, the bases 30 may be read as "first component." Hereinafter, the interior and exterior handles 40B and 40A will simply be referred to as "handle 40." In this embodiment, the handle 40 may also be read as "second component." In this embodiment, each base 30 and each handle 40 are made of aluminum, but they may be made of other materials.
[0015] Hereinafter, the end face of each base 30 on the side facing the door body 20 will be referred to as the "rear surface of the base 30". The end face of each base 30 opposite to the side facing the door body 20 will be referred to as the "front surface of the base 30". The upper end face of each base 30 will be referred to as the "upper surface of the base 30". The lower end face of each base 30 will be referred to as the "lower surface of the base 30". The end faces on both sides of each base 30 in the X direction will be referred to as the "side surfaces of the base 30s". In this embodiment, "side surfaces of the base 30s" may be read as "first end face".
[0016] In the following description, the end face of the handle 40 that faces the door body 20 will be referred to as the "rear face of the handle 40." The end face of the handle 40 that faces away from the door body 20 will be referred to as the "front face of the handle 40." The upper end face of the handle 40 will be referred to as the "upper face of the handle 40." The lower end face of the handle 40 will be referred to as the "lower face of the handle 40." The end faces on both sides of the handle 40 in the X direction will be referred to as the "side faces of the handle 40s." In this embodiment, "side faces of the handle 40s" may be read as "second end faces."
[0017] As shown in Figures 3 and 6, a curved portion 45 is provided on the rear surface of each handle 40, located between the upper and lower bases 30, projecting toward the door body 20. As shown in Figures 4 and 5, chamfered portions 49 are provided on both sides of the front surface of each handle 40 in the X direction, and on both the upper and lower edges. Chamfered portions 49 are also provided on both sides of the upper and lower surfaces of each handle 40 in the X direction.
[0018] Furthermore, chamfered edges 39 are provided on both sides of the upper surface of each upper base 30 in the X direction. Also, chamfered edges 39 are provided on both sides of the lower surface of each lower base 30 in the X direction.
[0019] Next, the mounting structure of the handles 40B and 40A on both the interior and exterior sides to the door body 20 shown in Figure 7 will be described. Two long bolt holes 21 are provided at the upper end of the X-side end of the door body 20, spaced apart in the vertical direction. The upper ends of the handles 40B and 40A on both the interior and exterior sides are connected to each other by two long bolts 51 that pass through these long bolt holes 21. Similarly, the lower ends of the handles 40B and 40A on both the interior and exterior sides are also connected to each other. More specifically, it is as follows.
[0020] The upper end of the interior handle 40B is provided with two long bolt mounting holes 41b and two short bolt threading holes 42. The two long bolt mounting holes 41b are spaced apart in the vertical direction. The two short bolt threading holes 42 are spaced apart in the vertical direction between the long bolt mounting holes 41b. Each long bolt mounting hole 41b penetrates the interior handle 40B in the Y direction, and an enlarged diameter portion 415 is provided at the front end for housing the head 515 of the long bolt 51. Each short bolt threading hole 42 extends from the rear surface to the front side of the interior handle 40B. The inner circumferential surface of each short bolt threading hole 42 is provided with a female thread.
[0021] The lower end of the handle 40B on the interior side is also provided with two long bolt mounting holes 41b and two short bolt screw holes 42, similar to the case of the upper end described above.
[0022] Each of the four bases 30 is provided with two long bolt through holes 31 and two short bolt mounting holes 32. The two long bolt through holes 31 are spaced apart in the vertical direction. The two short bolt mounting holes 32 are spaced apart in the vertical direction between the long bolt through holes 31. Both the long bolt through holes 31 and the short bolt mounting holes 32 penetrate the base 30 in the Y direction. An enlarged diameter portion 325 is provided at the rear end of each short bolt mounting hole 32 to accommodate the head 525 of the short bolt 52.
[0023] The upper end of the outdoor handle 40A is provided with two long bolt threading holes 41a and two short bolt threading holes 42. The two long bolt threading holes 41a are arranged side by side with a gap between them in the vertical direction. The two short bolt threading holes 42 are arranged side by side in the vertical direction between the long bolt threading holes 41a. Both the long bolt threading holes 41a and the short bolt threading holes 42 extend from the rear surface to the front surface of the outdoor handle 40A. Female threads are provided on the inner circumferential surface of both the long bolt threading holes 41a and the short bolt threading holes 42.
[0024] The lower end of the outdoor handle 40A is also provided with two long bolt screw holes 41a and two short bolt screw holes 42, similar to the case of the upper end described above.
[0025] At the upper end of the indoor handle 40B, two short bolts 52 are screwed into the short bolt threading holes 42 of the indoor handle 40B through the short bolt mounting holes 32 of the base 30. In this way, the base 30 is attached to the rear surface of the upper end of each indoor handle 40B. Similarly, the base 30 is attached to the lower end of the indoor handle 40B, and to the rear surfaces of the upper and lower ends of the outdoor handle 40A.
[0026] Then, at the upper ends of the handles 40B and 40A on both the interior and exterior sides, two long bolts 51 pass from the long bolt mounting hole 41b of the interior handle 40B, through the long bolt through hole 31 of the interior base 30, through the long bolt through hole 21 of the door body 20, and through the long bolt through hole 31 of the exterior base 30, and are screwed into the long bolt threading hole 41a of the exterior handle 40A. In this way, the upper ends of the handles 40B and 40A on both the interior and exterior sides are connected to each other with the door body 20 in between.
[0027] Similarly, the lower ends of the handles 40B and 40A on both the interior and exterior sides are also connected to each other with the door body 20 in between. In this way, each handle 40 is attached to the door body 20 via the upper and lower bases 30. Furthermore, a cap 418 is attached to the front end of each long bolt mounting hole 41b on the interior side handle 40B.
[0028] As shown in Figure 2, the handle side 40s and the base side 30s are located on the same plane in the ideal state where there are no dimensional errors in the joinery 100. Also, the top surface of the upper base 30 and the top surface of the handle 40 are located on the same plane in the same ideal state. Furthermore, the bottom surface of the lower base 30 and the bottom surface of the handle 40 are located on the same plane in the same ideal state.
[0029] A base groove 37 is recessed in the edge of the base side surface 30s on the handle 40 side, i.e., the front edge, extending vertically along the edge and opening towards the handle 40. Note that "base groove 37" may be read as "first groove". In this embodiment, as shown in Figure 9, the base groove 37 is a groove with a chamfered shape on the edge of the base side surface 30s on the handle 40 side.
[0030] The radius of curvature of the base groove 37 is smaller than the length of the equal sides of the isosceles triangle region cut out by each chamfered portion 39, 49 when viewed in the longitudinal direction. Therefore, the width of the base groove 37 in the Y direction is smaller than the width of the chamfered portions 39, 49. Also, the depth of the base groove 37 in the X direction is smaller than the depth of the chamfered portions 39, 49.
[0031] As shown in Figure 2, a handle groove 47 is recessed in the edge of the handle side 40s on the base 30 side, i.e., the rear edge, extending vertically along the edge and opening towards the base 30. Note that "handle groove 47" may be read as "second groove". In this embodiment, as shown in Figure 9, the handle groove 47 is a groove with a chamfered shape on the edge of the handle side 40s on the base 30 side.
[0032] The radius of curvature of the handle groove 47 is smaller than the length of the equal sides of the isosceles triangle region cut out by each chamfered portion 39, 49 when viewed in the longitudinal direction. Therefore, the width of the handle groove 47 in the Y direction is smaller than the width of the chamfered portions 39, 49. Also, the depth of the handle groove 47 in the X direction is smaller than the depth of the chamfered portions 39, 49.
[0033] Hereafter, the configuration in which each base groove 37 and each handle groove 47 are removed from the state of this embodiment shown in Figure 9, as shown in Figure 11, will be referred to as the comparative configuration. Below, the configuration and effects of this embodiment will be summarized in comparison with this comparative configuration.
[0034] In the comparative configuration shown in Figure 11, if the relative positions of the base side 30s and the handle side 40s are shifted in the X direction from their original relative positions due to dimensional errors in the joinery 100, as shown in Figure 12, the shift becomes noticeable, resulting in a decrease in the aesthetic appeal of the area between the base 30 and the handle 40.
[0035] In contrast, according to this embodiment, as shown in Figure 9, a base groove 37 is recessed in the edge of the base side surface 30s on the handle 40 side. And a handle groove 47 is recessed in the edge of the handle side surface 40s on the base side 30 side. As a result, as shown in Figure 10, even if the relative position of the base side surface 30s and the handle side surface 40s is shifted in the X direction from the original relative position, it is less noticeable compared to the comparative form shown in Figure 12. Therefore, a decrease in the aesthetic appeal of the area between the base 30 and the handle 40 can be suppressed.
[0036] As shown in Figure 2, the handle side 40s and the base side 30s are located on the same plane in an ideal state where there are no dimensional errors in the joinery 100. In such a case, the aforementioned X-direction misalignment becomes particularly noticeable, as shown in Figure 12. Therefore, the effect of this embodiment in making the misalignment less noticeable, as shown in Figure 10, can be demonstrated more significantly.
[0037] [Second Embodiment] Next, the second embodiment will be described with reference to Figures 13 and 14. The following embodiments will be described based on the first embodiment, focusing on the differences, and explanations of the same or similar aspects as the first embodiment will be omitted as appropriate.
[0038] This embodiment differs in that, as shown in Figure 13, the base groove 37 is a groove with a chamfered edge on the handle 40 side of the base side 30s. Furthermore, the handle groove 47 differs in that the chamfered edge on the base 30 side of the handle side 40s is also a groove with a chamfered edge.
[0039] In this embodiment as well, as shown in Figure 14, the X-direction displacement of the relative position between the base side surface 30s and the handle side surface 40s can be made less noticeable.
[0040] [Third Embodiment] Next, a third embodiment will be described with reference to Figures 15 and 16. This embodiment differs in that, in the top view shown in Figure 15, that is, in the longitudinal direction of the base groove 37 and the handle groove 47, both the base groove 37 and the handle groove 47 are rectangular in shape. This embodiment also makes it possible to make the X-direction displacement of the relative position between the base side surface 30s and the handle side surface 40s less noticeable, as shown in Figure 16.
[0041] [Fourth Embodiment] Next, a fourth embodiment will be described with reference to Figures 17-19. As shown in Figure 17, the door 100 is further equipped with an authentication device 90 for automatically unlocking.
[0042] The authentication device 90 is mounted on the exterior wall surface at a location on the X-side of the vertical frame 11. As shown in Figure 17, viewed in the Y direction, the authentication device 90 comprises a frame-shaped outer component 70 and an inner component 80 provided inside it. In this embodiment, "outer component 70" may be read as "first component," and "inner component 80" may be read as "second component."
[0043] Hereafter, the Y-side end face of the outer component 70 will be referred to as the "outer component front surface 70f." Note that "outer component front surface 70f" may also be read as "first end face." Similarly, hereafter, the Y-side end face of the inner component 80 will be referred to as the "inner component front surface 80f." Note that "inner component front surface 80f" may also be read as "second end face."
[0044] As shown in Figure 17, an outer groove 77 is recessed in the edge of the outer part front surface 70f on the side of the inner part 80, extending along the edge and opening towards the inner part 80. Note that "outer groove 77" may be read as "first groove". In this embodiment, as shown in Figure 18, the outer groove 77 is a groove with a chamfered shape on the edge of the outer part front surface 70f on the side of the inner part 80.
[0045] As shown in Figure 17, an inner groove 87 is recessed in the edge of the inner component surface 80s on the outer component 70 side, extending along the edge and opening towards the outer component side. Note that "inner groove 87" may be read as "second groove". In this embodiment, as shown in Figure 18, the inner groove 87 is a groove with a chamfered shape on the edge of the inner component surface 80f on the outer component 70 side.
[0046] According to this embodiment, as shown in Figure 19, even if the relative positions of the outer part 70 and the inner part 80 are shifted in the Y direction, the outer groove 77 and the inner groove 87 can make the shift less noticeable.
[0047] [Other embodiments] The above embodiments can be implemented with modifications, for example, as follows.
[0048] In Figure 1, the door body 20 is a swing door that opens and closes on the right long side when viewed from the outside, but it may also be a swing door that opens and closes on the left long side. Furthermore, the door body 20 may also be a sliding door that slides in the X direction.
[0049] The shapes of the base groove 37 and the handle groove 47 shown in Figure 10, etc., may be different. Specifically, for example, the base groove 37 may have the R-shaped surface shown in Figure 10, and the handle groove 47 may have the C-shaped surface shown in Figure 14.
[0050] In the fourth embodiment shown in Figure 18, the outer groove 77 and inner groove 87 may be C-shaped or rectangular instead of R-shaped.
[0051] The base groove 37 and handle groove 47 shown in Figure 10, etc., may be provided only on one side of the base 30s and handle 40s in the X direction, rather than on both sides of the base 30s and handle 40s in the X direction.
[0052] A base groove 37 may also be provided on the edge of the upper base 30 on the handle 40 side of the upper surface shown in Figure 3. Similarly, a handle groove 47 may also be provided on the edge of the handle 40 on the base 30 side of the upper surface. Likewise, a base groove 37 may also be provided on the edge of the lower base 30 on the handle 40 side of the lower surface. Furthermore, a handle groove 47 may also be provided on the edge of the handle 40 on the base 30 side of the lower surface.
[0053] As shown in Figure 7, instead of connecting the upper and lower ends of the handles 40B and 40A on both the interior and exterior sides with long bolts 51, a backing plate may be provided inside the door body 20. Then, the upper and lower ends of the handles 40B and 40A on both the interior and exterior sides may be fixed to the backing plate with bolts or the like.
[0054] The width of the base 30 in the X direction shown in Figure 9 may be slightly smaller than the width of the handle 40 in the X direction. Furthermore, in the ideal state where there are no dimensional errors in the joinery 100, the base side 30s and the handle side 40s may be slightly offset from each other in the X direction.
[0055] The chamfered portions 39 and 49 shown in Figures 4 and 5 may be rounded (R-shaped) instead of rounded (C-shaped). [Explanation of Symbols]
