Description

[Technical field]

[0001] The present disclosure relates to a guide member, a door roller unit, and a fitting. [Background technology]

[0002] Conventionally, sliding doors are known in which a roller is attached to the bottom frame of the sliding door, and when the sliding door is opened or closed, the roller runs on a rail on the bottom frame of the door fitting, allowing the door to be opened and closed smoothly. For example, the door fitting in Patent Document 1 is configured such that a roller case is attached in a downward groove of the bottom frame, and the roller in the case runs on a rail.

[0003] When installing a sliding door within the frame of a fixture, the position of the rollers is fine-tuned to adjust the position of the sliding door relative to the frame. In addition, the weight of the sliding door is applied to the rollers during use, which can cause the position of the sliding door to shift relative to the rollers. If the sliding door shifts out of position, a gap may appear between the sliding door and the frame, or the sliding door may become sluggish when opening and closing. In this case, the position of the case relative to the bottom frame is readjusted to the appropriate position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-116743 A Summary of the Invention [Problem to be solved by the invention]

[0005] Because the rollers are positioned toward the center and away from the widthwise ends of the bottom frame, it is difficult to adjust the position of the rollers from the outside of the sliding door in the width direction while the sliding door is attached to the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Below, a sliding window will be described as an example of an embodiment of the guide member, the roller unit, and the fitting, with reference to the drawings. The sliding window 100 is installed in an opening in the wall of a building. As shown in FIG. 1, the sliding window 100 comprises a frame 10, an outer screen 30, an inner screen 20, a roller member 5 shown in FIG. 3, and a guide member 1. The outer screen 30 and the inner screen 20 are examples of a screen. The outer screen 30 and the inner screen 20 have a glass panel 50 provided within a frame 40. FIG. 3 shows a cutaway view of the frame 40 around the roller unit 8.

[0012] In the following description, the direction perpendicular to the glass panel 50 of the outer screen 30 and the inner screen 20 is referred to as the inside-outside direction D. Of the directions perpendicular to the inside-outside direction D, the direction along the horizontal direction is referred to as the width direction W, and the vertical direction is referred to as the vertical direction V. As directions perpendicular to the inside-outside direction D, the vertical direction V and the width direction W may be collectively referred to as the surface direction.

[0013] The sliding window 100 has an outer screen 30 and an inner screen 20 installed inside a frame 10 that is installed along the surface direction. The outer screen 30 and the inner screen 20 move in the width direction W within the frame 10 to open and close the opening in the wall.

[0014] 1, the frame body 10 has a rectangular frame shape when viewed from the inside-outside direction D. The frame body 10 has an upper frame 11, a lower frame 12, and a pair of vertical frames 13. The frame body 10 is made of resin, for example. In addition, the frame body 10 may be made of a metal shaped material such as an aluminum alloy, or may be made of an aluminum-resin composite member formed by assembling an aluminum member and a resin member.

[0015] The upper frame 11 and the lower frame 12 extend in the width direction W. Each vertical frame 13 extends in the vertical direction V. Each vertical frame 13 is arranged at both ends of the upper frame 11 and the lower frame 12 in the width direction W. Each vertical frame 13 connects the end of the upper frame 11 in the width direction W to the end of the lower frame 12. An inner shoji 20 and an outer shoji 30 are arranged on the upper frame 11 and the lower frame 12. Hereinafter, the outer shoji 30 and the inner shoji 20 may be collectively referred to as the shoji 20, 30. As shown in Figures 1, 2 and 8, a lower rail 14 is formed on the lower frame 12. The lower rail 14 protrudes upward from the lower frame 12 and extends in the width direction W. Two lower rails 14 are formed at positions separated in the inward and outward directions D. Although not shown, two upper rails are also formed on the upper frame 11. The upper rail protrudes downward from the upper frame 11 and extends in the width direction W.

[0016] The outer screen 30 and the inner screen 20 are arranged within the frame body 10 along the upper rail and lower rail 14. The screens 20, 30 are arranged so as to be movable within the frame body 10 in the width direction W. The outer screen 30 and the inner screen 20 are arranged adjacent to each other in the inward / outward direction D. When the outer screen 30 and the inner screen 20 are closed, the outer screen 30 and the inner screen 20 block the inside of the frame body 10.

[0017] The outer screen 30 and the inner screen 20 have the same configuration. The frame 40 has a rectangular frame shape when viewed from the inside-outside direction D. The frame 40 has an upper frame 41, a lower frame 42, and a pair of vertical frames 43. The frame 40 is made of resin, for example. In addition, the frame 40 may be made of a metal shaped material such as an aluminum alloy, or may be made of an aluminum-resin composite material.

[0018] The upper frame 41 and the lower frame 42 extend in the width direction W. Each vertical frame 43 extends in the vertical direction V. Each vertical frame 43 is disposed at both ends of the upper frame 41 and the lower frame 42 in the width direction W. Each vertical frame 43 connects the end of the upper frame 41 in the width direction W to the end of the lower frame 42 in the width direction W. Of the pair of vertical frames 43, the vertical frame that abuts against the vertical frame 13 when the shoji screens 20, 30 are closed is referred to as the door end frame 431, and the vertical frame located on the opposite side of the door end frame 431 in the width direction W is referred to as the door joint frame 432. When the shoji screens 20, 30 are closed, the door joint frames 432 of the shoji screens 20, 30 are disposed in positions that overlap each other in the width direction W. The door frame 432 is provided with a known locking device 60.

[0019] The glass panel 50 is fitted within the frame 40. As shown in Fig. 8, the glass panel 50 has a double-glazed structure. In the glass panel 50 having the double-glazed structure, two glass plates are arranged apart in the inner / outer direction D. An air layer is formed between the two glass plates. The glass panel may be composed of a single glass plate.

[0020] As shown in FIG. 1 and FIG. 2, the lower end of each vertical frame 43 is inclined at 45 degrees with respect to the vertical direction V. Both ends of the lower frame 42 in the width direction W are inclined at 45 degrees with respect to the width direction W. The lower end of the vertical frame 43 and the end of the lower frame 42 in the width direction W are butted together and welded. The vertical frame 43 is a shaped member having a hollow inside. As shown in FIG. 3, a gap S is formed inside the connecting portion between the lower end of the joint frame 432 and the end of the lower frame 42 in the width direction W. As shown in FIG. 3 and FIG. 8, an opening 44 is formed at the lower end of the side surface 45 along the inside-outside direction D of the joint frame 432. The outside of the frame body 40 and the gap S are connected through the opening 44. As shown in FIG. 7, the lower frame 42 has a wheel hole 421 formed therethrough in the vertical direction V. The roller hole 421 is a hole for attaching the roller unit 8.

[0021] As shown in FIG. 1 to FIG. 3, a cap 70 is attached to the lower end of the side 45 of the joint frame 432. The cap 70 is a member that covers the opening 44. The cap 70 has a substantially flat plate shape. The cap 70 is made of, for example, resin. The cap 70 is arranged along the inward-outward direction D and is detachably attached to the side 45 of the joint frame 432. A rail opening 701 is formed at the lower end of the cap 70. The rail opening 701 is located at the middle of the cap 70 in the inward-outward direction D. The rail opening 701 is an opening formed by cutting out the lower end of the cap 70. The rail opening 701 is a substantially rectangular opening having a size that does not contact the lower rail 14. A screw hole 702 is formed at the upper end of the cap 70. The screw hole 702 penetrates the cap 70 in the thickness direction, i.e., the width direction W. A screw hole (not shown) also penetrates the side surface 45 of the joint frame 432 at a position corresponding to the screw hole 702. The cap 70 is removably attached to the side surface 45 of the joint frame 432 by using a screw 90.

[0022] Fig. 7 is a cross-sectional view taken along line P7-P7 in Fig. 6. As shown in Fig. 7, the roller member 5 has a roller 55 and a housing 7. The roller member 5 is disposed between the shoji screens 20, 30 and the lower rail 14. The roller member 5 is a member that supports the shoji screens 20, 30 so that they can move on the lower rail 14. When the shoji screens 20, 30 move to open or close in the width direction W, the roller 55 rotates on the lower rail 14, allowing the shoji screens 20, 30 to move smoothly in the width direction.

[0023] The door roller 55 is a known wheel that can rotate along the width direction W. The rotation shaft 56 of the door roller 55 is supported by the support member 62. The door roller 55 is supported rotatably relative to the support member 62. The support member 62 is housed in the housing 7. The support member 62 has a support 621 and an abutment wall 622. The support 621 has a plate shape and is arranged parallel to the lower rail 14. The abutment wall 622 extends in the inward / outward direction D from the end of the support 621 in the width direction W. The abutment wall 622 is located at the end of the support 621 on the side of the joint frame 432. The abutment wall 622 is arranged opposite to a first side wall 72 described later. The support 621 is formed with an arc hole 623 penetrating in the inward / outward direction D. The support member 62 and the housing 7 are connected to be relatively movable in the surface direction.

[0024] The housing 7 is a member that covers the door roller 55 from above. The housing 7 has an upper plate 75 and four side walls 71, 72, 73, and 74. The upper plate 75 is disposed above the door roller 55. As shown in FIG. 7, the upper plate 75 has two insertion pieces 751 and 752. The first insertion piece 751 protrudes upward from the upper plate 75 at the middle part in the width direction W. The second insertion piece 752 is located at the end part of the upper plate 75 in the width direction W, and protrudes outward in the width direction W beyond the first side wall 72.

[0025] Of the four side walls 71, 72, 73, and 74, the first side wall 72 is disposed on the side of the joint frame 432, and the second side wall 71 is disposed on the side of the door end frame 431. The third side wall 73 and the fourth side wall 74 are side walls extending parallel to the lower rail 14. The third side wall 73 and the fourth side wall 74 are disposed apart in the inward / outward direction D with the door roller 55 in between. The first side wall 72 is formed with a screw hole 721. As shown in FIG. 6, the third side wall 73 is provided with a locking protrusion 731. The locking protrusion 731 protrudes outward in the inward / outward direction D from the third side wall 73 in the vicinity of the second side wall 71. As shown in FIG. 6, the fourth side wall 74 is also provided with a locking protrusion 741. Each of the locking protrusions 731 and 741 is provided at a position corresponding to a support leg 61 described later. The fourth side wall 74 has a protrusion 742 that protrudes toward the door roller 55 along the inward / outward direction D. The protrusion 742 is inserted into the arc hole 623 of the support body 621.

[0026] The roller member 5 has a position adjustment mechanism 57. The position adjustment mechanism 57 is configured to be able to adjust the relative position between the roller member 5 and the shoji 20, 30. Since the shoji 20, 30 are supported by the roller member 5, the position adjustment mechanism 57 can adjust the inclination of the shoji 20, 30 in the surface direction. The housing 7, the support member 62, and the adjustment screw 91 constitute the position adjustment mechanism 57. The adjustment screw 91 is inserted into the screw hole 721 of the first side wall 72 and screwed into it. The screw head 912 of the adjustment screw 91 protrudes from the first side wall 72 to the outside in the width direction W. The screw tip 911 of the adjustment screw 91 abuts against the abutment wall 622. The support member 62 is connected to the roller 55 via the rotating shaft 56 and is supported by the housing 7 via the adjustment screw 91. The adjustment screw 91 is an example of an adjustment operation part.

[0027] When the adjustment screw 91 is screwed into the contact wall 622, the contact wall 622 is pushed, and the support member 62 moves relative to the housing 7 in the rotational direction. Specifically, when the adjustment screw 91 is screwed in, the support member 62 moves slightly clockwise as shown in FIG. 7. When the adjustment screw 91 is turned in the opposite direction and moves outward in the width direction W, toward the end frame 422, the contact wall 622 follows the screw tip 911, and the support member 62 moves slightly counterclockwise as shown in FIG. 7. Since the protrusion 742 is inserted into the arc hole 623, the protrusion 742 moves along the arc hole 623 when the support member 62 moves relative to the end frame 42. As a result, the inclination of the guide member 1 and the lower frame 42 changes. Depending on the position of the adjustment screw 91 in the width direction W with respect to the first side wall 72, the relative position of the support member 62 and the housing 7 in the surface direction changes. As described in more detail below, the wheel member 5 is attached to the lower frame 42, and the position adjustment mechanism 57 is configured to be able to adjust the inclination of the faces of the screens 20, 30 by changing the relative position between the support member 62 and the housing 7 by rotating the adjustment screw 91.

[0028] The roller unit 8 has a roller member 5 and a guide member 1. The guide member 1 is provided so as to cover the upper side of the housing 7 and both sides in the width direction W. As shown in FIG. 4 and FIG. 5, the guide member 1 has an upper member 2, a guide portion 3, and a support portion 6. The upper member 2 is a portion disposed in close proximity to the upper side of the roller member 5. The upper member 2 has a three-dimensional shape that is long in the width direction W. The upper member 2 has a size that allows it to be inserted into and locked in the roller hole 421. The guide portion 3 is provided so as to extend downward from a first end portion 21 in the width direction W of the upper member 2. The support portion 6 is provided so as to extend downward from a second end portion 22 in the width direction W of the upper member 2. A protrusion 23 that protrudes backward is formed at the center of the second end portion 22 of the upper member 2 in the inward / outward direction D. A locking wall 243 is formed between both ends in the inward / outward direction D of the second end portion 22 of the upper member 2 and the upper end portion of the support portion 6. The locking wall 243 extends downward from the lower surface of the upper member 2 .

[0029] 7, two locking holes 241, 242 are formed in the lower surface 24 of the upper member 2. The first locking hole 241 penetrates in the vertical direction V at the middle part in the width direction W of the upper member 2. The second locking hole 242 is formed between the first locking hole 241 and the guide part 3 in the width direction W. The second locking hole 242 is an opening that penetrates in the width direction W.

[0030] The guide portion 3 protrudes outward in the width direction W beyond the first end 21 of the upper member 2. The guide portion 3 has a guide body 36 and a lower wall 35. The guide body 36 is provided continuous with the lower end of the upper member 2. The guide body 36 has a substantially U-shape when viewed in the width direction W. The lower wall 35 is provided extending downward from the lower end of the guide body 36. A pair of legs 34 are provided adjacent to the lower wall 35 in the width direction W.

[0031] When viewed from the width direction W, a guide hole 33 is formed between the lower end of the upper member 2 and the guide body 36. The guide hole 33 is open so that a tool described later can be inserted. When viewed from the width direction W, an opening edge 331 of the guide hole 33 has a substantially U-shape. The lower part of the guide hole 33 has a curved shape that protrudes downward. The lower end of the guide hole 33 is formed to have a substantially equal size along the lower edge shape of the screw head 912 of the adjustment screw 91, i.e., along the arc shape. When viewed from the width direction W, the guide hole 33 is opened to a size that allows the screw head 912 of the adjustment screw 91 to be exposed. As shown in FIG. 7, the lower end of the guide hole 33 is formed to be substantially parallel to the axis of the adjustment screw 91.

[0032] As shown in Figures 4 to 7, an inclined surface 32 is formed on the guide body 36. The inclined surface 32 is inclined between an end 361 in the width direction W of the guide body 36 and an opening edge 331 of the guide hole 33. The end 361 also has a substantially U-shape. The inclined surface 32 is inclined such that the size of the U-shape decreases from the end 361 to the opening edge 331 of the guide hole 33. The lower wall 35 extends downward from the lower part of the guide body 36.

[0033] The support part 6 is provided to extend downward from an end part of the upper member 2 opposite the guide part 3 in the width direction W. The support part 6 has a pair of support legs 61. The pair of support legs 61 are provided to extend substantially horizontally at positions spaced apart in the inward / outward direction D. The pair of support legs 61 support the housing 7 of the door roller member 5.

[0034] The mounting structure of the door roller unit 8 will be described. As shown in Fig. 7, in the door roller unit 8, the upper part of the door roller member 5 is connected to the guide member 1. The upper member 2 of the guide member 1 is engaged with the bottom frame 42. The door roller member 5 is mounted to the bottom frame 42 via the guide member 1.

[0035] The first insertion piece 751 of the upper plate 75 is inserted into the first locking hole 241 of the lower surface 24 of the upper member 2 of the guide member 1, and the second insertion piece 752 is inserted into the second locking hole 242. The length of the first insertion piece 751 in the inward / outward direction D is slightly smaller than the opening dimension of the first locking hole 241. The length of the second insertion piece 752 in the inward / outward direction D is slightly smaller than the opening dimension of the second locking hole 242. The second end 753 in the width direction W of the upper plate 75 is disposed between the pair of locking walls 243. Therefore, the position of the housing 7 in the inward / outward direction D is regulated by inserting each of the insertion pieces 751 and 752 into each of the locking holes 241 and 242, respectively, and inserting the second end 753 of the upper plate 75 between the pair of locking walls 243.

[0036] As shown in Fig. 7, the second side wall 71 faces the support portion 6. As shown in Fig. 6, the locking projection 731 of the third side wall 73 and the locking projection 741 of the fourth side wall 74 are placed on and supported by the respective support legs 61. The housing 7 is supported by the guide member 1 by inserting the second insertion piece 752 into the second locking hole 242 and supporting the respective locking projections 731, 741 on the respective support legs 61. The abutting wall 622 abuts against a screw tip 911 of an adjustment screw 91 inserted into the first side wall 72. With the above-mentioned configuration, the door roller member 5 is supported by the guide member 1.

[0037] The contact wall 622 and the guide portion 3 are spaced apart in the width direction W. The guide portion 3 and the contact wall 622 are spaced apart to an extent that the adjustment screw 91 can advance and retreat in the width direction W. The guide hole 33 opens on an extension line of the screw head 912 of the adjustment screw 91 in the width direction W. The lower edge 913 of the screw head 912 and the lower end of the guide hole 33 are disposed at approximately the same height.

[0038] The upper member 2 of the guide member 1 is inserted into the wheel hole 421 of the bottom frame 42. The lower surface 231 of the protrusion 23 of the upper member 2 is engaged with the upper surface of the bottom frame 42.

[0039] Next, a method for attaching the door roller member 5 and the guide member 1 will be described. The guide member 1 is attached to the housing 7, and the door roller unit 8 is assembled. The second insertion piece 752 of the door roller member 5 is inserted into the second locking hole 242 of the guide member 1, while the first insertion piece 751 is inserted into the first locking hole 241. After that, the housing 7 is moved inward in the width direction W, and the locking protrusions 731, 741 are placed on the support legs 61. As a result, the door roller member 5 is supported by the guide member 1. The door roller unit 8 may be assembled in advance by assembling the guide member 1 and the door roller member 5 in a factory. The door roller unit 8 is inserted into the door roller hole 421 and fixed to the bottom frame 42.

[0040] After placing the shoji 20, 30 in the frame 10, the inclination of the shoji 20, 30 in the surface direction is adjusted. Specifically, as shown in FIG. 9, a tool such as a driver 200 is inserted from the opening 44, and the adjustment screw 91 is turned. The driver 200 is an example of an operating member. As shown in FIG. 8, when the shoji 20, 30 is attached, the wheel unit 8 is placed at the back side of the opening 44 of the joint frame 432. As shown by the symbol L in FIG. 3, the distance from the opening 44 to the screw head 912 of the adjustment screw 91 is far. The wheel unit 8 is located at the back of the narrow gap between the lower rail 14 and the lower frame 42 of the shoji 20, 30. Therefore, when the driver 200 is inserted into the opening 44 in the width direction W, the screw head 912 cannot be seen, and the tip of the driver 200 cannot be smoothly inserted into a predetermined screw hole. However, since the roller unit 8 includes the guide member 1, the tip of the driver 200 can be smoothly guided to the screw head 912.

[0041] Specifically, the guide hole 33 of the guide member 1 is disposed between the screw head 912 and the opening 44. An opening edge 331 of the guide hole 33 extends substantially parallel to the axis of the adjustment screw 91. Therefore, when the tip of the driver 200 is inserted into the opening 44, it comes into contact with the guide hole 33, and the tip of the driver 200 is smoothly guided toward the screw head 912. The lower end of the guide hole 33 is disposed at a height substantially equal to the lower edge 913 of the screw head 912. Therefore, after the tip of the driver 200 enters the guide hole 33, it is difficult for the driver 200 to enter the gap below the screw head 912, and the driver 200 can be smoothly guided to the screw head 912.

[0042] Since the inclined surface 32 is formed on the guide body 36, the tip of the driver 200 inserted near the end 361 of the guide body 36 is guided along the inclined surface 32 into the guide hole 33. When the tip of the driver 200 reaches the guide hole 33, the tip of the driver 200 is smoothly guided toward the screw head 912 as described above.

[0043] Since a bottom wall 35 is provided below the guide hole 33, the tip of the driver 200 can be prevented from entering below the guide hole 33. An inclined surface 32 is provided below the guide hole 33. Therefore, when the driver 200 is pushed in the width direction W, the tip of the driver 200 comes into contact with the inclined surface 32 and can be smoothly guided to the screw head 912. The guide portion 3 can guide the operating member that rotates the adjustment screw 91 toward the screw head 912.

[0044] Once the driver 200 is engaged with the adjustment screw 91, while checking the inclination of the surface of the screens 20 and 30, the adjustment screw 91 is rotated, and the adjustment screw 91 advances and retreats relative to the abutment wall 622. This changes the angle of the housing 7 relative to the support member 62. As a result, the inclination of the surface of the lower frame 42 to which the housing 7 is connected via the upper member 2 is adjusted.

[0045] After completing the adjustment of the inclination of the screens 20, 30 in the face direction, the opening 44 is covered with the cap 70 and the cap 70 is fixed to the joint frame 432 with the screw 90, thereby completing the adjustment of the screens 20, 30.
