Description

[Technical Field]

[0001] The present invention relates to a fitting having a shoji screen that moves along a guide portion of the upper frame. [Background technology]

[0002] In fittings equipped with sliding shoji screens, such as sliding doors, the shoji screens are placed in openings in a frame body and move by sliding along the guide sections of the upper and lower frames of the frame body. Furthermore, when an upward force is applied to the shoji screens, they may be displaced upward relative to the guide sections of the lower frame. Therefore, fittings have been known in the past that use a retaining bracket attached to the shoji screen to prevent the screen screens from coming off the frame body (see Patent Document 1).

[0003] In the conventional fittings described in Patent Document 1, the stop fittings are components that prevent the shoji screen from falling off, and when the shoji screen is displaced upward, they come into contact with the rail, which is the guide part of the upper frame. This reduces the amount of vertical movement of the shoji screen, and the shoji screen is held in place in the frame. However, in conventional fittings, the stop fittings are made of metal, and there is a risk of loud noise being generated when the stop fittings come into contact with the rail. It is also necessary to consider damage to the rail due to contact with the stop fittings. [Prior art documents] [Patent documents]

[0009] An embodiment of the fitting of the present invention will be described with reference to the drawings. The fixture of this embodiment is a fixture equipped with a sliding shoji screen that moves by sliding. Below, several embodiments of the fixture will be described using the example of the fixture being a sliding door. The fixture is a bathroom fixture (bathroom sliding door).

[0010] (First embodiment) Fig. 1 is a front view showing the fitting 1 of the first embodiment, and shows the fitting 1 installed in a building 2 as seen from the bathroom side. Fig. 2 is a cross-sectional view showing the fitting 1 of the first embodiment, and Fig. 3 is a vertical cross-sectional view showing the fitting 1 of the first embodiment. As shown in the figure, the fitting 1 is installed at the entrance to the bathroom and is positioned between the bathroom and the changing room. The fitting 1 is a three-panel sliding door and includes three shoji screens 3 and a frame 4 that surrounds the shoji screens 3. The fitting 1 and frame 4 are installed at an opening in the building 2, and the fitting 1 is positioned between the two spaces (bathroom and changing room) of the building 2 that are separated by the shoji screens 3.

[0011] When viewing the fitting 1 installed in the building 2 from the front (see Figure 1), the direction that is up and down is the up-down direction, and the direction that is left and right is the left-right direction. In Figure 1, the up-down direction is the vertical direction, and the left-right direction is the horizontal direction. The thickness direction of the shoji screen 3 is the front-to-back direction (the depth direction of the fitting 1) when viewing the fitting 3 installed in the building 2 from the front, and in Figure 1 it is the horizontal direction that is perpendicular to the left-to-right direction. In this way, the directions related to the fitting 1 are specified by the directions when it is installed in the building 2. Furthermore, the dressing room side and bathroom side of the fitting 1 are the dressing room side and bathroom side when it is installed in the building 2.

[0012] The shoji screen 3 is a sliding door shoji screen (movable shoji screen) that can be opened and closed, and is arranged so that it can move (slide) in the opening 4A of the frame body 4. The shoji screen 3 moves by sliding left and right in the opening 4A of the frame body 4. The opening 4A of the frame body 4 is opened and closed by the movement of the shoji screen 3. The three shoji screens 3 consist of a first shoji screen 3A (changing room side shoji screen) located on the changing room side, a second shoji screen 3B (bathroom side shoji screen) located on the bathroom side, and a third shoji screen 3C (middle shoji screen) located between the first shoji screen 3A and the second shoji screen 3B.

[0013] The shoji screen 3 has a rectangular frame 10 and a rectangular panel 11 fixed to the inside of the frame 10. The frame 10 has four frames 12 to 15 (an upper frame 12, a lower frame 13, and a pair of vertical frames 14, 15) that are fitted together. The upper frame 12 and the lower frame 13 are upper and lower horizontal frames located at the top and bottom of the frame 10, and extend in the left-right direction (horizontal direction) at the top and bottom of the frame 10. The pair of vertical frames 14, 15 (a first vertical frame 14, a second vertical frame 15) are side frames located on the left and right sides of the frame 10, and extend in the up-down direction (vertical direction) at the sides of the frame 10.

[0014] The ends of the upper frame 12, the lower frame 13, and the left and right vertical frames 14, 15 are connected to form a frame of four frames 12 to 15. The panel 11 is a resin panel made of synthetic resin, and is fitted inside the frame body 10. In the first shoji screen 3A and the second shoji screen 3B, of the pair of vertical frames 14, 15, one of the first vertical frame 14 is a door edge frame, and the other, the second vertical frame 15 is a door joint frame. In the third shoji screen 3C, both of the pair of vertical frames 14, 15 are door joint frames.

[0015] Of the three shoji screens 3, two, 3A and 3B, have a door edge portion 3D located at the door edge and an operating unit 16 attached to the door edge portion 3D. The door edge portion 3D of the shoji screens 3A and 3B is a first vertical frame 14 (door edge frame). The operating unit 16 is a handle, and is provided on the door edge portion 3D (first vertical frame 14) of the shoji screens 3A and 3B. The operating unit 16 operates the movement of the shoji screens 3A and 3B. The operating unit 16 is provided on each of the door edge portions 3D on the changing room side and the bathroom side, and protrudes from the door edge portion 3D toward the bathroom side and the changing room side, respectively. A force in the movement direction is applied to the shoji screens 3A and 3B using the operating unit 16, causing the shoji screens 3A and 3B to move.

[0016] The frame body 4 is an opening frame (door frame) that forms the opening 4A, and has four frames 5 to 8 (an upper frame 5, a lower frame 6, and a pair of vertical frames 7, 8) that are fitted together. The four frames 5 to 8 define the rectangular opening 4A of the frame body 4. The upper frame 5 and the lower frame 6 are horizontal frames located at the top and bottom of the frame body 4, and extend in the left-right direction at the top and bottom of the frame body 4. The pair of vertical frames 7, 8 are side frames located on the left and right sides of the frame body 4, and extend in the up-down direction at the sides of the frame body 4. The ends of the upper frame 5, the lower frame 6, and the left and right vertical frames 7, 8 are connected to form a frame of the four frames 5 to 8.

[0017] The upper frame 5 has three guide portions 5A to 5C located above each of the three shoji screens 3. The guide portions 5A to 5C of the upper frame 5 are upper guide portions that extend in the longitudinal direction (left-right direction) of the upper frame 5 and are arranged in parallel with a gap between them. The guide portion 5A located on the changing room side is the first upper guide portion, and the guide portion 5B located on the bathroom side is the second upper guide portion. The guide portion 5C located between the two guide portions 5A, 5B is the third upper guide portion. Here, the guide portions 5A to 5C of the upper frame 5 are guide rails (upper guide rails) that guide the shoji screens 3 above them, and consist of rail-shaped protruding pieces that protrude downward.

[0018] The bottom frame 6 has three guide portions 6A to 6C located below each of the three shoji screens 3. The guide portions 6A to 6C of the bottom frame 6 are lower guide portions that extend in the longitudinal direction (left-right direction) of the bottom frame 6 and are arranged in parallel with a gap between them. The guide portion 6A located on the changing room side is the first lower guide portion, and the guide portion 6B located on the bathroom side is the second lower guide portion. The guide portion 6C located between the two guide portions 6A, 6B is the third lower guide portion. Here, the guide portions 6A to 6C of the bottom frame 6 are guide rails (lower guide rails) that guide the shoji screens 3 below them, and consist of rail-shaped protrusions that protrude upward.

[0019] The three shoji screens 3 are respectively slidably connected to guide portions 5A to 5C of the upper frame 5 and guide portions 6A to 6C of the lower frame 6, which are opposed in the vertical direction. The shoji screens 3 are positioned below the guide portions 5A to 5C of the upper frame 5 and above the guide portions 6A to 6C of the lower frame 6, and are disposed between the guide portions 5A to 5C of the upper frame 5 and the guide portions 6A to 6C of the lower frame 6. The three shoji screens 3 slide on the guide portions 5A to 5C of the upper frame 5 and the guide portions 6A to 6C of the lower frame 6, respectively.

[0020] The guide portions 5A to 5C of the upper frame 5 and the guide portions 6A to 6C of the lower frame 6 are metal guide portions made of metal (for example, aluminum alloy). The shoji screen 3 is connected to the guide portions 5A to 5C of the upper frame 5 from below, placed on the guide portions 6A to 6C of the lower frame 6 from above, and connected to the guide portions 6A to 6C of the lower frame 6 from above. The shoji screen 3 moves (slides) along the guide portions 5A to 5C of the upper frame 5 and the guide portions 6A to 6C of the lower frame 6, and is guided in the longitudinal direction of the upper frame 5 and the lower frame 6 by the guide portions 5A to 5C and 6A to 6C. This allows the shoji screen 3 to move in the longitudinal direction (left and right direction) of the upper frame 5 and the lower frame 6.

[0021] When an upward force is applied, the shoji screen 3 is displaced upward. As a result, the shoji screen 3 is displaced toward the guide portions 5A to 5C of the upper frame 5, and is displaced upward relative to the guide portions 6A to 6C of the lower frame 6. Furthermore, when the shoji screen 3 is displaced upward to a position where it is disengaged from the guide portions 6A to 6C of the lower frame 6, the shoji screen 3 separates from the guide portions 6A to 6C of the lower frame 6, and the shoji screen 3 is disengaged from the guide portions 6A to 6C of the lower frame 6. Therefore, the shoji screen 3 has a removal prevention component. The removal prevention component is attached to the shoji screen 3 and prevents the shoji screen 3 from being disengaged from the guide portions 6A to 6C of the lower frame 6 and the frame body 4.

[0022] The anti-detachment parts are attached to the top of the shoji screen 3. Here, the anti-detachment parts are attached to the top of the vertical frames 14, 15 of the shoji screen 3. Furthermore, the shoji screen 3 is mainly subjected to an upward force from the operating unit 16. Therefore, the anti-detachment parts are provided at least in a location located above the operating unit 16 of the shoji screens 3A, 3B. The anti-detachment parts are attached to the top of the door edge 3D (first vertical frame 14) of the shoji screens 3A, 3B, and are located above the operating unit 16.

[0023] If the operating unit 16 of the shoji screens 3A and 3B is a large handle, the user can operate the shoji screens 3A and 3B by gripping the operating unit 16. For this reason, a large handle is suitable as the operating unit 16, for example, for persons with disabilities or the elderly. However, if a large handle is used, if the user falls while gripping the operating unit 16, the shoji screens 3A and 3B may be lifted along with the operating unit 16, which may lead to unexpected behavior. To prevent such a situation, it is effective to provide a stopper component above the operating unit 16 of the shoji screens 3A and 3B. Furthermore, when the weight of the shoji screen 3 is light or when the vertical dimension of the shoji screen 3 is larger than the horizontal dimension of the shoji screen 3, the shoji screen 3 is prone to tilting, and a stopper component is therefore effective.

[0024] Fig. 4 is a diagram showing a portion of the fitting 1 of the first embodiment including the anti-detachment component 20, and shows a part of the upper frame 5, the upper part of the shoji screen 3, and the anti-detachment component 20 as viewed from one side in the left-right direction. Fig. 4 also shows only one shoji screen 3 (first shoji screen 3A) out of the three shoji screens 3. Fig. 5 is a diagram showing the upper part of the shoji screen 3 and the anti-detachment component 20 of the first embodiment as viewed from the direction of arrow X1 in Fig. 4. Fig. 6 is a cross-sectional view showing the attachment location of the anti-detachment component 20 of the shoji screen 3 of the first embodiment.

[0025] As shown in the figure, the shoji screen 3 has a door roller 17. The door roller 17 is attached to the top of the shoji screen 3 and contacts the lower end of the guide portion 5A (first upper guide portion) of the upper frame 5 from below. The door roller 17 is also guided by the guide portion 5A of the upper frame 5 and moves along the guide portion 5A of the upper frame 5. As a result, the shoji screen 3 moves while being guided in the longitudinal direction (left-right direction) of the guide portion 5A of the upper frame 5.

[0026] The fitting 1 is equipped with a retaining part 20 that is detachably attached to the shoji screen 3. The retaining part 20 is attached to the top of the shoji screen 3 by a screw 21 so that it can move up and down. The screw 21 is screwed into the threaded part of a turn nut 22 and is engaged with it. The turn nut 22 is inserted through an insertion hole 3F formed in the side surface 3E of the shoji screen 3 (door edge 3D), and is attached to the side surface 3E of the shoji screen 3 as the screw 21 is screwed in. The retaining part 20 is attached to the top of the side surface 3E of the shoji screen 3 via the turn nut 22.

[0027] The anti-detachment component 20 is disposed below the guide portion 5A of the upper frame 5, spaced downward from the guide portion 5A (here, the lower end portion of the guide portion 5A) of the upper frame 5. The anti-detachment component 20 is disposed with a gap between it and the guide portion 5A of the upper frame 5 in the vertical direction, and faces the guide portion 5A of the upper frame 5. When the shoji screen 3 is stationary or when the shoji screen 3 moves normally along the guide portion 5A, the anti-detachment component 20 does not come into contact with the guide portion 5A of the upper frame 5. In contrast, when the shoji screen 3 is displaced upward, the anti-detachment component 20 comes into contact with the guide portion 5A of the upper frame 5, stopping the upward displacement of the shoji screen 3.

[0028] The anti-detachment component 20 stops the shoji screen 3 at a position where it will not come off the guide portions 6A to 6C of the bottom frame 6 (a position where it is held by the guide portions 6A to 6C). The shoji screen 3 is also prevented from coming off the guide portions 6A to 6C of the bottom frame 6, and is held by the guide portions 6A to 6C of the bottom frame 6. In this way, the anti-detachment component 20 contacts the guide portion 5A of the top frame 5, thereby restricting the upward displacement of the shoji screen 3 and preventing the shoji screen 3 from coming off the guide portions 6A to 6C of the bottom frame 6 and the frame body 4. The dimension of the gap between the anti-detachment component 20 and the guide portion 5A of the top frame 5 is set to a dimension that can prevent the shoji screen 3 from coming off the frame body 4.

[0029] The anti-detachment component 20 has a base member 30 that serves as the base of the anti-detachment component 20 and a contact member 40 that contacts the guide portion 5A of the upper frame 5. The base member 30 is a metal fixing member (metal member) that is attached to the shoji screen 3 with screws 21 and is detachably fixed to the shoji screen 3. By fixing the base member 30, the anti-detachment component 20 is attached to the shoji screen 3. The base member 30 is arranged along the side portion 3E (see FIG. 6) of the shoji screen 3 and two opposing portions 3G that protrude from the side portion 3E and face each other, and fits snugly between the two opposing portions 3G. This prevents the base member 30 from rotating, and allows the base member 30 and anti-detachment component 20 to be attached with a single screw 21. The base member 30 is arranged downward and spaced apart from the guide portion 5A of the upper frame 5 and protrudes upward toward the guide portion 5A of the upper frame 5.

[0030] The contact member 40 is a mounting member (resin member) made of resin (here, synthetic resin), and is detachably attached to the base member 30. The contact member 40 is attached to an upper portion of the base member 30 that protrudes upward, and protrudes upward from the base member 30 toward the guide portion 5A of the upper frame 5. The contact member 40 is spaced downward from the guide portion 5A of the upper frame 5 and is disposed below the guide portion 5A of the upper frame 5. The contact member 40 is disposed with a gap between it and the guide portion 5A of the upper frame 5 in the vertical direction, and faces the guide portion 5A of the upper frame 5. When the shoji screen 3 is displaced upward, the contact member 40 comes into contact with the guide portion 5A of the upper frame 5 to stop the upward displacement of the shoji screen 3.

[0031] Fig. 7 is a perspective view showing the removal prevention component 20 of the first embodiment, and Fig. 8 is a side view of the removal prevention component 20 of the first embodiment as seen from the direction of arrow X2 in Fig. 7. Fig. 7 omits the illustration of the rounded shapes (R-shapes) provided on the edges and corners of the removal prevention component 20. Figs. 7(A) and 8(A) show the removal prevention component 20 in an exploded state, and Figs. 7(B) and 8(B) show the removal prevention component 20 with the contact member 40 attached to the base member 30.

[0032] As shown in the figure, the base member 30 of the anti-detachment component 20 has a fixed portion 31 that is fixed to the shoji screen 3, and an attached portion 32 to which the contact member 40 is attached. The attached portion 32 of the base member 30 has an attached portion 33 to which the contact member 40 is attached, an engaged hole 34 with which the contact member 40 engages, and an abutted portion 35 with which the contact member 40 abuts. The fixed portion 31 is the lower portion of the base member 30, and the attached portion 32 is the upper portion of the base member 30. The fixed portion 31 has a long hole 36 that extends in the vertical direction.

[0033] The screw 21 is inserted through the elongated hole 36 of the fixing part 31 and attached to the turn nut 22 and the shoji screen 3. The fixing part 31 is attached to the shoji screen 3 by the screw 21. With the screw 21 loosened, the base member 30 and the anti-detachment part 20 are moved up and down, changing the position of the screw 21 in the longitudinal direction (up and down direction) of the elongated hole 36. This adjusts the position of the anti-detachment part 20 in the up and down direction. Thereafter, the screw 21 is tightened to fix the fixing part 31, base member 30, and anti-detachment part 20 to the shoji screen 3.

[0034] The retaining part 20 is attached to the shoji screen 3 by the elongated hole 36 of the fixing part 31 and the screw 21 so that it can move up and down. When placing the shoji screen 3 in the opening 4A of the frame body 4, the retaining part 20 is placed in a lower position, and the shoji screen 3 is inserted into the opening 4A of the frame body 4. After placing the shoji screen 3 in the opening 4A of the frame body 4, the retaining part 20 is moved upward, and the retaining part 20 prevents the shoji screen 3 from coming off. Furthermore, when the positional relationship between the shoji screen 3 and the guide part 5A of the upper frame 5 changes, for example by performing fitting adjustments (roller adjustments) in response to construction errors in the frame body 4 of the fitting 1, the retaining part 20 is moved up and the position of the retaining part 20 in the up and down direction is adjusted.

[0035] The base member 30 has an attached portion 33, an engaged hole 34, and an abutted portion 35 provided in the attached portion 32. The attached portion 32, the attached portion 33, the engaged hole 34, and the abutted portion 35 are formed on the guide portion 5A side (upper side) of the upper frame 5 with respect to the fixed portion 31, and are positioned above the fixed portion 31. The attached portion 33 is a protruding portion of the base member 30, and protrudes upward from the fixed portion 31 toward the guide portion 5A of the upper frame 5. The attached portion 33 is also a receiving portion that receives the contact member 40, and has an insertion portion 37 that protrudes upward at its upper tip (upper end).

[0036] The engaged hole 34 is a hole-shaped engaged portion that penetrates the base member 30, and is provided on the fixed portion 31 side (lower side) of the attached portion 33, and is located between the attached portion 33 and the fixed portion 31. The abutted portions 35 are located in two places on both sides of the attached portion 33 and the engaged hole 34 of the base member 30. The two abutted portions 35 are protruding portions that protrude from the attached portion 33 (here, the lower end portion of the attached portion 33), and are formed with the attached portion 33 and the engaged hole 34 sandwiched between them.

[0037] Contact member 40 of anti-detachment component 20 has a contact portion 41 that contacts guide portion 5A of upper frame 5, and an attachment portion 42 that is attached to attached portion 32 of base member 30. Furthermore, attachment portion 42 of contact member 40 has an attachment portion 43 that is attached to base member 30, an engagement portion 44 that engages with base member 30, and an abutment portion 45 that abuts against base member 30. Contact portion 41 is the upper end of contact member 40, and is formed on the guide portion 5A side (upper side) of upper frame 5 with respect to attachment portion 42, attachment portion 43, engagement portion 44, and abutment portion 45. Furthermore, contact portion 41 protrudes upward from attachment portion 42 and attachment portion 43 toward guide portion 5A of upper frame 5, and is positioned above attachment portion 42 and attachment portion 43.

[0038] The contact portion 41 is a recess formed in the upper end of the contact member 40, and is recessed downward and open upward. The contact member 40 has the recess that is the contact portion 41, and an attachment portion 43, an engagement portion 44, and an abutment portion 45 that are provided in the attachment portion 42. The attachment portion 43 is a receiving portion that can be attached to the attachment portion 33 of the base member 30, and receives and fits into the attachment portion 33 of the base member 30. As a result, the attachment portion 43 is attached to and held in the attachment portion 33. The attachment portion 43 also has a fitting portion 46 that includes an insertion hole 46A, and a clamping portion 47 that is located below the fitting portion 46.

[0039] The insertion hole 46A of the fitting portion 46 is a through-hole that passes through the contact member 40, and the fitting portion 46 is formed in the upper part of the mounting portion 43. The insertion portion 37 of the mounting portion 33 of the base member 30 is inserted into the insertion hole 46A of the fitting portion 46 and moves upward to fit into the fitting portion 46 of the mounting portion 43. The clamping portion 47 of the mounting portion 43 is clamped between the mounting portion 33 of the base member 30 and the shoji screen 3 (here, the upper side surface portion 3E of the shoji screen 3). In this state, the clamping portion 47 of the mounting portion 43 is pressed against the shoji screen 3 by the mounting portion 33 and is held between the mounting portion 33 and the shoji screen 3.

[0040] The abutting portions 45 are located at two locations on both sides of the mounting portion 43 and the engaging portion 44 of the contact member 40. The two abutting portions 45 are protruding portions that protrude from the mounting portion 43 (here, the lower end portion of the mounting portion 43), are formed with the mounting portion 43 and the engaging portion 44 sandwiched between them, and each abuts against the abutted portion 35 of the base member 30. The mounting portion 43 of the contact member 40 is pressed from the opposite side of the shoji screen 3 by the abutted portion 33 of the base member 30 at a location below the fitting portion 46 and the insertion portion 37. Furthermore, the fitting portion 46 of the contact member 40 is pressed from the shoji screen 3 side by the insertion portion 37 of the base member 30, and the abutting portion 45 of the contact member 40 is pressed from the shoji screen 3 side by the abutted portion 35 of the base member 30.

[0041] The contact member 40 has one engaging portion 44. The engaging portion 44 is provided on the lower portion of the contact member 40 and is located below the mounting portion 43. The engaging portion 44 is an elastically deformable protrusion (engaging protrusion) that protrudes downward from the mounting portion 43 and is formed in a hook shape. When attaching the contact member 40 to the base member 30, the contact member 40 is moved downward toward the base member 30, and the mounting portion 43 of the contact member 40 is attached to the mounting portion 33 of the base member 30. At this time, the engaging portion 44 is inserted into the engaging hole 34 of the base member 30 while coming into contact with the base member 30 and elastically deforming. After being inserted into the engaging hole 34, the engaging portion 44 returns to its shape before elastic deformation.

[0042] With the mounting portion 43 of the contact member 40 mounted to the mounted portion 33 of the base member 30, the engaging portion 44 of the contact member 40 is disposed within the engaged hole 34 of the base member 30, fits into the engaged hole 34, and engages with the engaged hole 34. The contact member 40 (mounting portion 42) is attached to the mounted portion 33, the abutted portion 35, and the engaged hole 34 by the mounting of the mounting portion 43 to the mounted portion 33, the abutted portion 35, and the engagement of the engaging portion 44 with the engaged hole 34. As a result, the contact member 40 is attached to the mounted portion 32 of the base member 30 and the base member 30. The engaging portion 44 engaging with the engaged hole 34 prevents the contact member 40 from moving upward relative to the base member 30 and also prevents the contact member 40 from coming off the base member 30.

[0043] The engaging portion 44 of the contact member 40 is a snap that engages with the engaged hole 34 of the base member 30 by snap-fitting, and has a locking portion 48. The locking portion 48 is a protrusion (hook portion) formed on the engaging portion 44. When the engaging portion 44 is engaged with the engaged hole 34, the locking portion 48 of the engaging portion 44 catches on the edge of the engaged hole 34 and is locked to the edge of the engaged hole 34. Here, the locking portion 48 of the engaging portion 44 catches on the upper edge of the engaged hole 34 from below and is locked to the upper edge of the engaged hole 34. The edge of the engaged hole 34 prevents the locking portion 48 from moving upward, and the locking portion 48 and the engaging portion 44 are held in the engaged hole 34.

[0044] 9 to 11 are diagrams showing the procedure for attaching the anti-detachment component 20 of the first embodiment to a shoji screen 3. Similar to FIG. 5, FIGS. 9 and 10 show the upper part of the shoji screen 3 and the anti-detachment component 20. Also, FIG. 9 shows the anti-detachment component 20 before it is attached to the shoji screen 3, and FIG. 10 shows the anti-detachment component 20 after it has been attached to the shoji screen 3. FIG. 11 is a view of the shoji screen 3 and the anti-detachment component 20 as seen from the direction of arrow X3 in FIG. 10, and similar to FIG. 4, shows the upper part of the shoji screen 3 and the anti-detachment component 20.

[0045] As shown in the figure, when attaching the anti-detachment component 20, the turn nut 22 is inserted into the insertion hole 3F of the shoji screen 3 (see FIG. 9). Also, the screw 21 is inserted into the elongated hole 36 of the fixing portion 31 of the base member 30, and the screw 21 is screwed into the threaded portion of the turn nut 22. At this time, the screw 21 is not tightened, and the fixing portion 31 of the base member 30 is temporarily fixed to the shoji screen 3 by the screw 21 so that it can move up and down (see FIGS. 10 and 11). In this way, the anti-detachment component 20 is positioned at a position (lower position) below the position (anti-detachment position) where the anti-detachment component 20 can be attached to the shoji screen 3.

[0046] The shoji screen 3 is inserted into the opening 4A of the frame body 4, and the shoji screen 3 is connected to the guide portion 5A of the upper frame 5 and the guide portion 6A of the lower frame 6. Next, the anti-detachment part 20 is moved upward, and the position of the anti-detachment part 20 in the vertical direction is adjusted to place the anti-detachment part 20 in the anti-detachment position (see Figures 4 and 5). In this state, the screw 21 is tightened to fix the fixing part 31 of the base member 30 to the turn nut 22 and the shoji screen 3. This completes the attachment of the anti-detachment part 20 to the shoji screen 3.

[0047] The contact portion 41 of the contact member 40 is spaced downward from the guide portion 5A of the upper frame 5 and is disposed below the guide portion 5A of the upper frame 5. The contact portion 41 is disposed with a gap between it and the guide portion 5A of the upper frame 5 in the vertical direction and faces the guide portion 5A of the upper frame 5. Here, the guide portion 5A of the upper frame 5 is a guide rail and is disposed inside the contact portion 41, which is a recess of the contact member 40. The contact portion 41 is disposed below the guide portion 5A and is disposed on both sides of the guide portion 5A in the thickness direction of the shoji screen 3 (the projection direction of the upper frame 5), sandwiching the guide portion 5A therebetween.

[0048] When the shoji screen 3 is stationary or when it moves normally along the guide portion 5A, the contact portion 41 of the contact member 40 does not come into contact with the guide portion 5A of the upper frame 5. As the shoji screen 3 moves, the contact portion 41 of the contact member 40 moves along the guide portion 5A with a gap between it and the guide portion 5A. In contrast, when the shoji screen 3 is displaced upward, the contact portion 41 of the contact member 40 comes into contact with the guide portion 5A of the upper frame 5, stopping the upward displacement of the shoji screen 3. Furthermore, when the shoji screen 3 is displaced in the thickness direction, the contact portion 41 of the contact member 40 comes into contact with the guide portion 5A, stopping the displacement of the guide portion 5A in the thickness direction of the shoji screen 3.

[0049] As explained above, in the fitting 1 of the first embodiment, when the shoji screen 3 is displaced upward, the metal base member 30 of the anti-detachment component 20 does not come into contact with the guide portion 5A of the upper frame 5, and only the resin contact member 40 of the anti-detachment component 20 comes into contact with the guide portion 5A. Therefore, compared to when a metal member comes into contact with the guide portion 5A, it is possible to suppress the generation of noise due to contact between the anti-detachment component 20 and the guide portion 5A, and damage to the guide portion 5A. It is also possible to suppress the generation of abnormal noise, including noise (rubbing noise) due to rubbing between the anti-detachment component 20 and the guide portion 5A. Because the base member 30 fixed to the shoji screen 3 is made of metal, the anti-detachment component 20 can also be firmly attached to the shoji screen 3.

[0050] With the fixing portion 31 of the base member 30 fixed to the shoji screen 3, the mounting portion 43 of the contact member 40 is mounted to the mounted portion 33 of the base member 30, and the engaging portion 44 of the contact member 40 engages with the engaged hole 34 of the base member 30. This allows the contact member 40 to be stably held on the base member 30. Furthermore, the clamping portion 47 of the mounting portion 43 of the contact member 40 can be clamped and firmly held between the mounted portion 33 of the base member 30 and the shoji screen 3. The locking portion 48 of the engaging portion 44 is locked onto the edge of the engaged hole 34, allowing the contact member 40 to be easily attached to the base member 30.

[0051] The contact portion 41, which is a recess in the contact member 40, can restrict displacement of the shoji screen 3 in the thickness direction. An upward force is mainly applied to the shoji screen 3 via the operating portion 16. Therefore, by providing the anti-detachment component 20 above the operating portion 16 of the shoji screen 3, it is possible to effectively prevent the shoji screen 3 from displacing upward and from coming off. If the contact member 40 becomes damaged, it can be removed from the base member 30 and easily replaced with a new contact member 40.

[0052] It is possible to attach only one anti-detachment part 20 to the shoji screen 3, or to attach multiple anti-detachment parts 20 to the shoji screen 3. Furthermore, the anti-detachment part 20 may be provided only above the operating part 16 of the shoji screen 3, or may be provided in one or more other locations on the shoji screen 3 in addition to the location above the operating part 16 of the shoji screen 3. The anti-detachment part 20 may not be provided above the operating part 16 of the shoji screen 3, but may be provided in one or more other locations on the shoji screen 3.

[0053] The panel 11 of the shoji screen 3 is not limited to a resin panel made of synthetic resin, and may be another panel (for example, a glass panel). The anti-detachment component 20 may be attached to the shoji screen 3 without using the turn nut 22. In this case, for example, a back plate is provided on the inside of the first vertical stile 14 (see FIG. 6), and the anti-detachment component 20 is attached to the shoji screen 3 by threading a screw 21 into a screw hole in the back plate. Alternatively, depending on the thickness of the side surface portion 3E of the shoji screen 3, the anti-detachment component 20 may be attached to the shoji screen 3 by threading a screw 21 into a screw hole in the side surface portion 3E. The guide portions 5A to 5C of the upper frame 5 and the guide portions 6A to 6C of the lower frame 6 may be guide portions other than guide rails (for example, guide grooves into which the shoji screen 3 is placed).

[0054] The fitting 1 is not limited to a three-panel sliding door and a bathroom sliding door, but may be other fittings (for example, a sliding door other than a three-panel sliding door, a sliding door, or fittings other than those for bathrooms). Furthermore, before the fitting 1 is installed, the anti-detachment parts 20 are attached to the shoji screen 3 in advance, and when the fitting 1 is installed, the shoji screen 3 with the anti-detachment parts 20 is placed in the opening 4A of the frame 4. On the other hand, if the shoji screen 3 of the existing fitting 1 does not have the anti-detachment parts 20, the anti-detachment parts 20 may be attached to the shoji screen 3 to add it.

[0055] Next, other embodiments of the anti-detachment component 20 for the fitting 1 will be described. In the following embodiments, the same matters as in the first embodiment will not be described, and differences from the first embodiment will be mainly described. Furthermore, in the following embodiments, the same names as in the first embodiment will be used for components that correspond to those in the first embodiment.

Fig. 12 omits the illustration of the rounded shapes (R-shapes) provided on the edges and corners of the removal prevention component 20. Figs. 12(A) and 13(A) show the removal prevention component 20 in an exploded state, and Figs. 12(B) and 13(B) show the removal prevention component 20 with the contact member 40 attached to the base member 30.

[0057] As shown in the figure, the abutment portions 35 of the base member 30 are located at two positions on both sides of the engaged hole 34 of the base member 30. The two abutment portions 35 are located between the mounting portion 33 and the fixed portion 31, sandwiching the engaged hole 34 between them. The engaged hole 34 is located between the two abutment portions 35. The contact member 40 has two engaging portions 44 arranged parallel to each other, and the abutment portions 45 of the contact member 40 are the two engaging portions 44. The locking portions 48 of the two engaging portions 44 hook onto the edges of the engaged holes 34 located on both sides in the thickness direction of the shoji screen 3 and are locked to the edges of the engaged holes 34. In this state, the two abutment portions 45 of the contact member 40 abut against the abutment portions 35 of the base member 30 on both sides of the engaged hole 34 of the base member 30.

[0058] (Third embodiment) Fig. 14 is a perspective view showing a removal prevention component 20 of the third embodiment, and Fig. 15 is a side view of the removal prevention component 20 of the third embodiment as seen from the direction of arrow X5 in Fig. 14. Fig. 14 omits the illustration of the rounded shapes (R-shapes) provided on the edges and corners of the removal prevention component 20. Figs. 14(A) and 15(A) show the removal prevention component 20 in an exploded state, and Figs. 14(B) and 15(B) show the removal prevention component 20 with the contact member 40 attached to the base member 30.

[0059] As shown in the figure, the base member 30 does not have an abutment portion 35. Furthermore, the contact member 40 does not have an abutment portion 45, and the fitting portion 46 of the mounting portion 43 does not have an insertion hole 46A. The mounting portion 43 of the contact member 40 is attached to the mounting portion 33 of the base member 30 from the shoji screen 3 side, and the insertion portion 37 of the mounting portion 33 of the base member 30 is fitted into the fitting portion 46 of the mounting portion 43 from the opposite side of the shoji screen 3. Double-sided tape 50 is provided between the mounting portion 43 and the mounting portion 33. The mounting portion 43 of the contact member 40 is adhered to the mounting portion 33 of the base member 30 with the double-sided tape 50, and is attached to the mounting portion 33 of the base member 30. In this way, the contact member 40 is attached to the base member 30.

[0060] The contact member 40 has one engaging portion 44. The engaging portion 44 is a protrusion provided on the lower end of the contact member 40. When the mounting portion 43 of the contact member 40 is mounted to the mounted portion 33 of the base member 30, the engaging portion 44 is inserted into the engaged hole 34 of the base member 30 and engages with the engaged hole 34. The locking portion 48 of the engaging portion 44 gets caught on the upper edge of the engaged hole 34 from below and is locked to the upper edge of the engaged hole 34.

[0061] The contact member 40 can be easily attached to the base member 30 by adhering the attachment portion 43 to the attachment receiving portion 33. The attachment portion 43 of the contact member 40 may be adhered to the attachment receiving portion 33 of the base member 30 with an adhesive other than the double-sided tape 50 (for example, an adhesive). Furthermore, in the anti-detachment components 20 of the first and second embodiments, the attachment portion 43 of the contact member 40 may be adhered to the attachment receiving portion 33 of the base member 30.

[0062] As mentioned above, building materials are A fitting comprising a shoji screen that moves along a guide portion of an upper frame, and a stopper part that is attached to the shoji screen and arranged with a gap between it and the guide portion, The anti-detachment part is a fixture having a metal base member fixed to the shoji screen and a resin contact member attached to the base member that comes into contact with the guide portion when the shoji screen is displaced upward. Therefore, when the anti-detachment parts of the shoji door of the building material come into contact with the guide part of the upper frame, it is possible to suppress the generation of noise caused by contact between the anti-detachment parts and the guide part, and damage to the guide part. In addition, because the base member fixed to the shoji door is made of metal, the anti-detachment parts can be firmly attached to the shoji door.

[0063] The base member has a fixed portion fixed to the shoji screen, and an attached portion and an engaged hole located above the fixed portion, The contact member has an attachment portion that is attached to the attachment portion, and an engagement portion that engages with the engagement hole. Therefore, the contact member can be stably held on the base member.

[0064] The mounting portion has a clamping portion that is clamped between the mounted portion and the shoji screen. Therefore, the clamping portion of the mounting portion of the contact member can be firmly clamped between the mounting portion of the base member and the shoji screen.

[0065] The engaging portion has a locking portion that is locked to the edge of the engaged hole. Therefore, by engaging the engaging portion with the edge of the engaged hole, the contact member can be easily attached to the base member.

[0066] The mounting portion is adhered to the mounting portion. Therefore, the contact member can be easily attached to the base member by adhering the attachment portion to the attachment receiving portion.

[0067] the guide portion is a guide rail, The contact member has a recess that comes into contact with the guide rail when the guide rail is disposed inside and the shoji screen is displaced upward. Therefore, the recess can regulate the displacement of the shoji screen in the thickness direction.
