Description

[Technical Field]

[0001] The present invention relates to a fitting having a sliding screen that moves while being guided by a rail. [Background technology]

[0002] In fittings with sliding shoji screens, the screens are guided by rails to move and open / close. At this time, rollers on the screen roll on the rails, causing the screen to move along the rails. Conventionally, as such fittings, fittings with door rollers that support the screen so that it can move while being guided by the rails are known (see Patent Document 1).

[0003] In the conventional fittings described in Patent Document 1, door rollers have multiple wheels each rotatably supported on an axle, and are installed at two locations on the bottom frame of the shoji screen. The shoji screen moves along the rail, guided by the multiple wheels of the door rollers that roll on the rail. However, in fittings, it is sometimes necessary to adjust the force required to move the shoji screen depending on the weight of the shoji screen and the way in which it is moved. However, conventional fittings do not have a structure for adjusting the force required to move the shoji screen, making it difficult to adjust the force required to move the shoji screen.

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the fitting of the present invention will be described with reference to the drawings. The fittings of this embodiment are fitted with at least one shoji screen that slides in the opening and closing direction, and are installed in an opening of a building. The fittings are also installed between the interior (indoor) and exterior (outdoor) of the building, and the shoji screen closes the opening of the building. Below, two embodiments of the fittings will be explained, taking the case where the fitting is a single sliding window as an example.

[0010] (First embodiment) FIG. 1 is a front view showing the fitting 1 of the first embodiment, showing the fitting 1 installed in a building as viewed from the front. As shown in the figure, the fitting 1 comprises two shoji screens 2 and 3 and a frame 4 surrounding the shoji screens 2 and 3. One of the two shoji screens 2 and 3, shoji screen 2, is a fixed shoji screen that is fixed to the fitting 1, and is arranged on one side in the left-right direction S inside the frame 4, and is fixed to the frame 4. The other of the two shoji screens 2 and 3, shoji screen 3, is a movable shoji screen that moves by sliding, and is arranged inside the frame 4 so that it can move (slide) in the left-right direction S. An opening 4A in the frame 4 is opened and closed by shoji screen 3, which is a single-sliding shoji screen.

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

[0012] One of the shoji screens 2 closes one side of the inside of the frame body 4 in the left-right direction S. The opening 4A of the frame body 4 is a part of the inside of the frame body 4 that is not closed by the shoji screen 2, and is formed inside the frame body 4 (a part of the inside of the frame body 4 on the other side of the inside of the frame body 4 in the left-right direction S) by the frame body 4 and the shoji screen 2. The other shoji screen 3 slides and moves in the left-right direction S inside the frame body 4 between a position (closed position) where it closes (fully closed) the opening 4A of the frame body 4, and a position (open position) where it opens (fully open) the opening 4A of the frame body 4. In the open position, the shoji screen 3 overlaps the shoji screen 2 at a part of the inside of the frame body 4.

[0013] The shoji screen 3 has a rectangular frame 3A and a panel 3B arranged inside the frame 3A. The frame 3A has four frames 3C to 3F (upper frame 3C, lower frame 3D, and a pair of vertical frames 3E and 3F) that are fitted together. The frames 3C to 3F are the frame materials that make up the frame 3A, and are each made of machined wood. The upper frame 3C and lower frame 3D are horizontal frames on the top and bottom of the frame 3A, extending horizontally (left-right direction S) at the top and bottom of the frame 3A. The pair of vertical frames 3E and 3F are side frames located on the left and right sides of the frame 3A, extending vertically (up-down direction R) on the sides of the frame 3A. The ends of the upper frame 3C, the lower frame 3D, and the left and right vertical frames 3E and 3F are connected to form a frame of frames 3C to 3F. Panel 3B is glass (for example, plate glass, double glazing, or laminated glass) that is fitted into frame 3A and held by frame 3A and frames 3C to 3F.

[0014] The frame body 4 is a rectangular opening frame (window frame) and is installed in an opening in a building. The frame body 4 also has four frames 10-13 (an upper frame 10, a lower frame 11, and a pair of vertical frames 12, 13) that are fitted together. The frames 10-13 are frame materials that make up the frame body 4, and are each made of shaped members (extruded shapes) formed by extrusion molding. The upper frame 10 and the lower frame 11 are the upper and lower horizontal frames of the frame body 4, and extend horizontally at the top and bottom of the frame body 4. The pair of vertical frames 12, 13 are side frames located on the left and right sides of the frame body 4, and extend vertically at the sides of the frame body 4. The ends of the upper frame 10, the lower frame 11, and the left and right vertical frames 12, 13 are connected to form the frames 10-13. The opening 4A of the frame body 4 is formed in a square shape by an upper frame 10, a lower frame 11, one of a pair of vertical frames 12, 13, and a shoji screen 2.

[0015] Fig. 2 is a vertical cross-sectional view showing the stile 3D and the bottom frame 11 of the fitting 1 of the first embodiment, showing the stile 3D and the bottom frame 11 cut along a plane including the vertical direction R and the thickness direction T of the shoji screen 3. Fig. 2 also shows a portion of the bottom frame 11 and a simplified view of the structure of the stile 3D. As shown in the figure, the frame body 4 has rails 14 attached to the lower frame 11. The rails 14 protrude upward from the lower frame 11 toward where the shoji screen 3 is located, and extend in the longitudinal direction (left-right direction S) of the lower frame 11. The shoji screen 3 is placed on the rails 14 from above, and moves while being guided by the rails 14. The shoji screen 3 is also guided in the moving direction by the rails 14, and moves along the rails 14 in the longitudinal direction (left-right direction S) of the rails 14.

[0016] The shoji screen 3 has a plurality of rollers 5, 6 (first roller 5, second roller 6) and door rollers 7A, 7B (first door roller 7A, second door roller 7B) on which the rollers 5, 6 are mounted. The rollers 5, 6 are rolling (rotatable) bodies and are placed on a rail 14 from above. The rollers 5, 6 of the shoji screen 3 roll on the rail 14, moving the shoji screen 3 along the rail 14. The rollers 5, 6, while supporting the shoji screen 3, are guided by the rail 14 and roll along the rail 14 in the longitudinal direction of the rail 14. The shoji screen 3 is guided by the rail 14 via the rollers 5, 6 and moves along the rail 14.

[0017] The door rollers 7A and 7B are door roller parts (first door roller part, second door roller part) having rollers 5 and 6, and are attached to the lower frame 3D, which is the lower end of the shoji screen 3. The door rollers 7A and 7B and the rollers 5 and 6 are located above the rail 14 and are arranged on the lower frame 3D facing the rail 14 located below. The shoji screen 3 has two door rollers 7A and 7B, which are supported by the rollers 5 and 6 of each of the two door rollers 7A and 7B so that they can move along the rail 14. Of the two door rollers 7A and 7B (see Figure 1), the first door roller 7A is located on one side in the left-right direction S of the longitudinal center of the lower frame 3D, and the other, the second door roller 7B, is located on the other side in the left-right direction S of the longitudinal center of the lower frame 3D.

[0018] Fig. 3 is an exploded perspective view of the door rollers 7A and 7B of the fitting 1 of the first embodiment, showing the configuration of the door rollers 7A and 7B as seen from diagonally above. The first door roller 7A and the second door roller 7B differ only in the rollers 5 and 6. Therefore, Fig. 3 shows the configuration of the first door roller 7A, and for the configuration of the second door roller 7B, only the second roller 6, which is different from the first roller 5 of the first door roller 7A, is shown. As shown in the figure, door rollers 7A and 7B have a main unit 20 including rollers 5 and 6, a mounting frame 21 that mounts the main unit 20 to the shoji screen 3, and an adjustment unit 22 that adjusts the position of the main unit 20. The adjustment unit 22 is interposed between the main unit 20 and the mounting frame 21, and connects the main unit 20 to the mounting frame 21.

[0019] The main unit 20 has two roller units 30, each including two rollers 5, 6, and a support frame 31 that supports the two roller units 30. The roller unit 30 has a roller frame 32, two rollers 5, 6 arranged inside the roller frame 32, and two shafts 33 that rotatably support each of the rollers 5, 6. The roller frame 32 has a pair of frame walls 34 that face each other and are spaced apart in the thickness direction T of the shoji screen 3. The two rollers 5, 6 are each attached to the shafts 33 and arranged side by side in the left-right direction S between the pair of frame walls 34. The shafts 33 span the pair of frame walls 34 and are attached to the pair of frame walls 34 and the roller frame 32.

[0020] The rollers 5 and 6 of the roller unit 30 are connected to the roller frame 32 by a shaft 33, and rotate to one side and the other side in the circumferential direction around the shaft 33. The support frame 31 has a pair of support walls 35 that face each other and are spaced apart in the thickness direction T of the shoji screen 3. The two roller units 30 are each attached to a support shaft 36 and are arranged side by side in the left-right direction S between the pair of support walls 35. The support shaft 36 spans the pair of support walls 35 and is attached to the pair of support walls 35 and the support frame 31. The roller unit 30 is supported by the support shaft 36 and attached to the support frame 31.

[0021] The adjustment unit 22 has an inner frame 40 that supports the support frame 31, an outer frame 41 that houses the inner frame 40, and two adjustment blocks 42 fixed to both ends of the outer frame 41 in the left-right direction S. The inner frame 40 has a pair of inner wall portions 43 that face each other at a distance in the thickness direction T of the shoji screen 3. The support frame 31 is attached to a connecting shaft 37 and is disposed between the pair of inner wall portions 43. The connecting shaft 37 spans the pair of inner wall portions 43 and is attached to the pair of inner wall portions 43 and the inner frame 40. The support frame 31 and the main unit 20 are supported by the connecting shaft 37 and attached to the inner frame 40.

[0022] The outer frame 41 has a pair of outer wall portions 44 that face each other at a distance in the thickness direction T of the shoji screen 3 and protrude from the inner frame 40 on both sides in the left-right direction S. The pair of inner wall portions 43 of the inner frame 40 have guide portions 45 that are inclined with respect to the left-right direction S, and the pair of outer wall portions 44 of the outer frame 41 have engagement portions 46 that engage with the guide portions 45 so as to be movable in the inclined direction of the guide portions 45. A screw 47 is threadedly engaged with one of the two adjustment blocks 42. The screw 47 is connected to the inner frame 40 and displaces in the left-right direction S as it rotates, moving the inner frame 40 in the left-right direction S. As the inner frame 40 moves, the engagement position of the engagement portion 46 with the guide portions 45 changes in the inclined direction of the guide portions 45, and the inner frame 40 moves in the inclined direction of the guide portions 45. As a result, the inner frame 40, the main unit 20, and the rollers 5 and 6 move in the up-down direction R.

[0023] The mounting frame 21 is a case that opens downward and has a pair of opposing wall portions 50 that face each other at an interval in the thickness direction T of the shoji screen 3, and a fixed portion 51 that is fixed to the shoji screen 3. The adjustment unit 22 is disposed between the pair of opposing wall portions 50 so as to be movable in the thickness direction T of the shoji screen 3, and is attached to the mounting frame 21 by a mounting shaft 52. A coil spring 53 is provided around the mounting shaft 52. The coil spring 53 is sandwiched between one opposing wall portion 50 and the adjustment unit 22, and urges the adjustment unit 22 toward the other opposing wall portion 50. By fixing the fixed portion 51 of the mounting frame 21 to the bottom frame 3D of the shoji screen 3, the mounting frame 21 and door rollers 7A, 7B are attached to the bottom frame 3D and the shoji screen 3, and the multiple rollers 5, 6 of the door rollers 7A, 7B are connected to the bottom frame 3D and the shoji screen 3. The shoji screen 3 moves on the rail 14 together with the rollers 5 and 6 as the rollers 5 and 6 roll on the rail 14 .

[0024] Fig. 4 is a view of door rollers 7A and 7B of the fitting 1 of the first embodiment as seen from one side in the thickness direction T of the shoji screen 3. Fig. 4A shows the first door roller 7A, and Fig. 4B shows the second door roller 7B. Fig. 5 is a cross-sectional view showing the rollers 5 and 6 of the fitting 1 of the first embodiment, showing the rollers 5 and 6 cut along a plane including the axial direction of the rollers 5 and 6. Fig. 5A shows the first roller 5, and Fig. 5B shows the second roller 6.

[0025] As shown in the figure, the multiple rollers 5, 6 of the shoji screen 3 have at least one first roller 5 and at least one second roller 6, each with a different rolling resistance. The rolling resistance of the rollers 5, 6 is the resistance force that occurs in the opposite direction to the direction of travel of the rollers 5, 6 when they roll on the rail 14. The rolling resistance of the second roller 6 rolling on the rail 14 is greater than the rolling resistance of the first roller 5 rolling on the rail 14, and the force required to roll the second roller 6 on the rail 14 is greater than the force required to roll the first roller 5. Therefore, the first roller 5 rolls more easily on the rail 14 than the second roller 6, and the second roller 6 rolls more difficultly on the rail 14 than the first roller 5.

[0026] The shoji screen 3 has a first door roller 7A equipped with only a first roller 5, and a second door roller 7B equipped with only a second roller 6 (see Figure 4). The first door roller 7A has at least one first roller 5, and the second door roller 7B has at least one second roller 6. Here, the first door roller 7A has multiple first rollers 5, and the second door roller 7B has multiple second rollers 6. The first door roller 7A and the second door roller 7B have the same number of rollers 5, 6 (four). The shoji screen 3 has one first door roller 7A and one second door roller 7B, and the multiple rollers 5, 6 of the shoji screen 3 include four first rollers 5 and four second rollers 6. The shoji screen 3 is supported by the first roller 5 of the first door roller 7A and the second roller 6 of the second door roller 7B, which roll on the rail 14, and moves along the rail 14 as the first roller 5 and second roller 6 roll.

[0027] As described above, the rollers 5, 6 provided on the shoji screen 3 include a first roller 5 and a second roller 6 having a greater rolling resistance than the first roller 5. When each of the rollers 5, 6 rolls on the rail 14, the resistance force generated in the direction opposite to the direction of travel of the second roller 6 is greater than the resistance force generated in the direction opposite to the direction of travel of the first roller 5. The rollers 5, 6 also include bearings 5A, 6A attached to the shaft member 33 and wheels 5B, 6B mounted on the bearings 5A, 6A (see FIG. 5). The bearings 5A, 6A are bearings provided around the shaft member 33 and are held by the shaft member 33. The wheels 5B, 6B are ring-shaped members provided around the bearings 5A, 6A and rotatably held by the bearings 5A, 6A. The bearing 5A of the first roller 5 and the bearing 6A of the second roller 6 are different types of bearings, and the rolling resistance of the first roller 5 and the rolling resistance of the second roller 6 rolling on the rail 14 are different from each other.

[0028] In the multiple rollers 5, 6 consisting of two types of rollers 5, 6, the first roller 5 has a rolling bearing 5A, and the second roller 6 has a sliding bearing 6A. The rolling bearing 5A is, for example, a ball bearing or a roller bearing, and in this case, it is a ball bearing with multiple balls built in. The wheel 5B of the first roller 5 is attached to the rolling bearing 5A, rotatably supported by the rolling bearing 5A, and rotates around the rolling bearing 5A. The sliding bearing 6A is, for example, a resin bearing, a sintered bearing, or a multi-layer metal bearing, and in this case, it is a resin bearing made of a synthetic resin containing oil. The wheel 6B of the second roller 6 is attached to the sliding bearing 6A, rotatably supported by the sliding bearing 6A, and rotates around the sliding bearing 6A.

[0029] The first roller 5 and the second roller 6 have markings (identification markings 5C, 6C) to distinguish them from each other (see FIG. 4). The identification markings 5C, 6C are markings for distinguishing the first roller 5 from the second roller 6, and the first roller 5 and the second roller 6 are distinguishable from each other by the identification markings 5C, 6C. The identification marking 5C of the first roller 5 is a marking different from the identification marking 6C of the second roller 6, and is attached to the surface of the first roller 5. The identification marking 6C of the second roller 6 is a marking different from the identification marking 5C of the first roller 5, and is attached to the surface of the second roller 6.

[0030] The identification markings 5C of the first roller 5 and the identification markings 6C of the second roller 6 are, for example, marks, symbols, signs, or colorings that enable the first roller 5 and the second roller 6 to be distinguished from each other, and are different from each other. Here, the identification markings 5C of the first roller 5 and the identification markings 6C of the second roller 6 are different colors (colorings) on their respective surfaces. In Figures 3 and 4, the color of the surface of the second roller 6 (identification marking 6C) is shown by hatching. The surfaces of the wheels 5B of the first roller 5 and the wheels 6B of the second roller 6 are colored different colors from each other, and the first roller 5 and the second roller 6 are distinguished from each other by the identification marks 5C and 6C, which are the colors of the wheels 5B and 6B, respectively.

[0031] The force required to start moving the shoji screen 3 and the force required to move the shoji screen 3 correspond to the rolling resistance of the first rollers 5 in a shoji screen 3 equipped with only multiple first rollers 5, and the force required to move the shoji screen 3 corresponds to the rolling resistance of the second rollers 6 in a shoji screen 3 equipped with only multiple second rollers 6. By including first rollers 5 and second rollers 6 with different rolling resistances in the multiple rollers 5, 6 of a shoji screen 3, compared to a shoji screen 3 equipped with only rollers 5, 6 of the same rolling resistance, the force required to start moving the shoji screen 3 and the force required to move the shoji screen 3 can be easily changed and adjusted. Therefore, the force required to move the shoji screen 3 can be easily adjusted according to the rolling resistance of each of the first rollers 5 and second rollers 6. Furthermore, the force required to move the shoji screen 3 can be adjusted using only multiple rollers 5, 6, which also helps prevent increases in the cost of the fitting 1.

[0032] By using different types of bearings for the bearing 5A of the first roller 5 and the bearing 6A of the second roller 6, the first roller 5 and the second roller 6 can roll smoothly while the rolling resistance of the second roller 6 can be easily made greater than the rolling resistance of the first roller 5. Furthermore, the first door roller 7A has only the first roller 5, and the second door roller 7B has only the second roller 6. Therefore, by providing both the first door roller 7A and the second door roller 7B to the shoji screen 3, it is possible to prevent mistakes in the combination of the rollers 5 and 6 of the shoji screen 3 and to reliably provide the first roller 5 and the second roller 6 to the shoji screen 3. The door rollers provided to the shoji screen 3 can also be consolidated into two door rollers 7A and 7B, the first door roller 7A and the second door roller 7B.

[0033] The identification marks 5C and 6C on the rollers 5 and 6 prevent the first roller 5 and the second roller 6 from being confused, and the first roller 5 and the second roller 6 can be reliably installed on the shoji screen 3. Furthermore, the identification mark 5C on the first roller 5 and the identification mark 6C on the second roller 6 are colors applied to their respective surfaces, and the surfaces of the first roller 5 and the second roller 6 are different colors. Therefore, the first roller 5 and the second roller 6 can be easily distinguished from each other by appearance, and confusion between the first roller 5 and the second roller 6 can be reliably prevented.

[0034] The bearing 5A of the first roller 5 may be a bearing other than a ball bearing, and the bearing 6A of the second roller 6 may be a bearing other than a resin bearing. The rolling resistance of the first roller 5 and the rolling resistance of the second roller 6 may be made different from each other by a method other than using different types of bearings 5A, 6A. For example, the first roller 5 may be provided with a bearing 5A, and the second roller 6 may not be provided with a bearing 6A. In this case, the wheel 6B of the second roller 6 is rotatably mounted on the shaft 33. The frames 3C to 3F of the frame body 3A of the shoji screen 3 are not limited to wooden frames, and may be other frames, such as frames made of shaped members formed by extrusion molding (extruded frames).

[0035] The fitting 1 is not limited to a single sliding window, but may be other fittings with a shoji screen that moves guided by a rail (for example, a double sliding window, a window with three or more shoji screens, or a sliding door). The present invention is not limited to fitting 1 with a rail 14 on the bottom frame 11, but can also be applied to other fittings with a rail that guides the shoji screen (for example, fittings with rails installed on the floor surface, top-hung fittings). In top-hung fittings, the rail is installed on the wall above the top frame or shoji screen, and a door roller and multiple rollers are installed above the shoji screen. The shoji screen is suspended from the rail by the multiple rollers and moves while being guided by the rail.

[0036] (Second embodiment) Next, we will explain the fitting 1 of the second embodiment. For the fitting 1 of the second embodiment, we will omit explanations of the same matters as the fitting 1 of the first embodiment and will mainly explain matters that differ from the fitting 1 of the first embodiment. Furthermore, for the fitting 1 of the second embodiment, the same names and symbols as the fitting 1 of the first embodiment will be used for the components that correspond to the components of the fitting 1 of the first embodiment.

[0037] FIG. 6 is a view of the door rollers 7A and 7B of the fitting 1 of the second embodiment as viewed from one side in the thickness direction T of the shoji screen 3. As shown in the figure, in the fitting 1 of the second embodiment, the shoji screen 3 has multiple door rollers 7A, 7B, each of which is provided with both a first roller 5 and a second roller 6. The door rollers 7A, 7B have at least one first roller 5 and at least one second roller 6. Here, the door rollers 7A, 7B have multiple first rollers 5 and multiple second rollers 6, and also have the same number of first rollers 5 and second rollers 6.

[0038] The shoji screen 3 has two door rollers 7A and 7B, and the first door roller 7A and the second door roller 7B each have two first rollers 5 and two second rollers 6. The first rollers 5 and second rollers 6 are arranged alternately on the first door roller 7A and the second door roller 7B. The shoji screen 3 is supported by the first rollers 5 and second rollers 6 of the door rollers 7A and 7B, which roll on a rail 14, and moves along the rail 14 as the first rollers 5 and second rollers 6 roll. By providing the shoji screen 3 with multiple door rollers 7A and 7B, each of which has a first roller 5 and a second roller 6, it is possible to easily provide both the first rollers 5 and the second rollers 6 on the shoji screen 3.

[0039] FIG. 7 is a view showing another example of door rollers 7A and 7B of the fitting 1 of the second embodiment, as viewed from one side in the thickness direction T of the shoji screen 3. As shown in the figure, the first rollers 5 may be arranged adjacent to each other and the second rollers 6 may be arranged adjacent to each other in each of the first door roller 7A and the second door roller 7B. Alternatively, two adjacent first rollers 5 may be arranged between two second rollers 6, and two adjacent second rollers 6 may be arranged between two first rollers 5.

[0040] As described above, the present embodiment discloses the fittings described in the following (1) to (6).

[0041] (1) A fitting equipped with a sliding screen that moves along a rail, The shoji screen has a plurality of rollers that roll on the rail to move the shoji screen along the rail, The plurality of rollers include a first roller and a second roller having a greater rolling resistance than the first roller.
