Description

[Technical field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Generally, sashes in residential building fixtures have drainage holes in the frame on the lower side of the sash to prevent rainwater from accumulating. The larger the drainage hole, the better the drainage. Drainage holes are often provided in the rail part of the sash where the screen door is located, which is the most outdoor side. If drainage holes are provided in the rail part located on the most outdoor side, there are problems such as adverse effects on insect resistance and light leakage from the outdoor side.

[0003] Patent document 1 discloses that by blocking the outer frame member of the wheel mechanism opposite a rectangular cutout opening formed in the bottom rail for draining water, etc., it is possible to prevent light, etc. from entering the room through the cutout opening. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-53266 A Summary of the Invention [Problem to be solved by the invention]

[0005] If drainage holes are provided in the rail section closest to the outdoors, there are problems with adverse effects such as insect resistance and light leakage from the outdoors, so drainage holes are generally designed to have the minimum necessary opening area.

[0006] If the opening area of ​​the drainage hole is made small, depending on the relationship between the opening area and the amount of water accumulated in the frame part below the sash, surface tension may act on the water at the opening of the drainage hole, and drainage may not be proper. Even if rainwater accumulates in the frame part below the sash, the water will drain when the weather dries out due to clear skies, but since it takes time to drain, water will remain accumulated for a long time even after the rain has stopped, causing discomfort to users and hygiene problems.

[0007] One common solution to the discomfort felt by users and hygienic issues is to make the drainage hole larger. However, if the drainage hole is made larger, the parts that make up the rollers must be enlarged to cover the hole, and the exposed parts reduce the design.

[0008] The present disclosure has been made in consideration of the above points, and aims to provide a fixture that can prevent rainwater from accumulating and reduce design quality. [Means for solving the problem]

[0009] A first aspect of the present disclosure is a fixture comprising an opening frame formed by framing an upper frame, a lower frame, and a pair of left and right vertical frames all around, and a sliding door movably arranged on the opening frame, wherein the lower frame has a lower rail portion that guides the movement of the sliding door, the sliding door has a wheel unit including wheels that run along the lower rail portion, the lower rail portion has a water drainage opening that penetrates in a forward direction, and the wheel unit is formed to a size that includes an area that overlaps with the outline of the water drainage opening when facing the water drainage opening in the forward direction, and has a shielding portion that blocks the water drainage opening at a position away from the outdoors in the forward direction, and a guide portion that is positioned on the indoor side in the forward direction relative to the shielding portion and is capable of contacting water located in the water drainage opening to guide the movement of the water.

[0016] The drainage openings 12d are disposed near both the left and right ends of the lower rail portion 12b, respectively, at positions away from the vertical frame 13. The drainage openings 12d are disposed symmetrically on the lower rail portion 12b in the left-right direction. Below, the left drainage opening 12d will be described, and a description of the right drainage opening 12d will be omitted.

[0017] The drainage opening 12d is rectangular and extends in the left-right direction. The drainage opening 12d may be rectangular and extends in the up-down direction, but is preferably extended in the left-right direction from the viewpoint of drainage described later. The drainage opening 12d is disposed in a position lower than the protrusion 12c in the lower rail portion 12b and higher than the bottom wall 12e in the lower frame 12. The drainage opening 12d is an opening for draining rainwater and the like that has accumulated in the space surrounded by the lower rail portion 12a for the shoji screen, the lower rail portion 12b, and the bottom wall 12e. The drainage opening 12d penetrates the lower rail portion 12b in the forward direction.

[0018] The shoji screen 20 is constructed by fitting glass 24 inside a frame body formed by a four-way frame assembly of an upper frame 21, a lower frame 22, and a pair of vertical frames 23 on the left and right. The shoji screen 20 is installed in a set both indoors and outdoors.

The shoji screen lower rail section 12a is inserted into the lower insertion groove 22a formed in the lower frame 22 of the shoji screen 20. The shoji screen roller 25, which is rotatably arranged in the lower insertion groove 22a of the lower frame 22, is placed on the upper surface of the shoji screen lower rail section 12a so as to be rollable. The shoji screen 20 can be opened and closed along the longitudinal direction of the upper frame 11 and the lower frame 12, which is the viewing direction.

[0019] The screen door 30 is a surface material in which a screen 34 is stretched inside a frame assembled on all four sides by a screen door upper frame 31, a screen door lower frame 32, and a pair of left and right screen door vertical frames 33. The screen door 30 is placed on the outdoor side of the outdoor-facing shoji screen 20. The screen door 30 has a wheel unit 50 including a wheel 51. The wheel 51 is freely rotatable around an axis extending in the forward direction.

[0020] The screen door 30 has an upper screen door rail portion 11b inserted into an upper screen door insertion groove 31a formed in an upper screen door frame 31. The screen door 30 has a lower screen door rail portion 12b inserted into a lower screen door insertion groove 32a formed in a lower screen door frame 32. A door roller unit 50 is provided in the lower screen door insertion groove 32a. The screen door 30 has a door roller 51 that runs along the lower rail portion 12b. The screen door 30 has the door roller 51 rollably placed on the upper surface of the protrusion 12c on the lower rail portion 12b. The screen door 30 can be opened and closed in the left-right direction along the protrusion 12c on the lower rail portion 12b.

[0021] The roller units 50 are provided at both left and right ends of the screen door bottom frame 32. The roller units 50 are arranged symmetrically in the left and right directions on the screen door bottom frame 32. Below, the left roller unit 50 will be described, and a description of the right roller unit 50 will be omitted.

[0022] 3 to 5, the door roller unit 50 has a door roller 51, an inner frame 52, a middle frame 53, an outer frame 54, and a torsion coil spring 55. In Fig. 3, the upper screen door frame 31, the lower screen door frame 32, and the pair of left and right screen door vertical frames 33 of the screen door 30 are not shown.

[0023] The door roller 51 is fixed to the inner frame 52 by the rotating shaft 51a so as to be rotatable from the indoor side. The door roller 51 has a rolling surface 51b and a flange 51c. The rolling surface 51b is an outer peripheral surface centered on the rotating shaft 51a. The rolling surface 51b is a surface that rolls on the upper surface of the protrusion 12c of the lower rail portion 12b. The flange 51c extends from the indoor end of the rolling surface 51b to the outside in the radial direction centered on the rotating shaft 51a. When the door roller 51 rolls on the upper surface of the protrusion 12c on the rolling surface 51b, the flange 51c can engage with the lower rail portion 12b from the indoor side, as shown in FIG. 2.

[0024] When the roller unit 50 rolls on the upper surface of the projection 12c on the rolling surface 51b, the guide portion 61 described below provided on the outer frame 54 can engage with the lower rail portion 12b from the outdoor side. In the roller unit 50, when the flange portion 51c and the guide portion 61 are engaged with and guided by the lower rail portion 12b from both sides in the projection direction, the rolling surface 51b can stably roll on the upper surface of the projection 12c.

[0025] The inner frame 52 is disposed at the center side in the left-right direction in the roller unit 50. The inner frame 52 has a protrusion 52a, an engagement groove 52b, an inner frame body 52c, and a protruding wall 52d. The inner frame body 52c and the protruding wall 52d are disposed on the outdoor side of the lower rail portion 12b. The protruding wall 52d protrudes to the left from the inner frame body 52c. The width dimension of the protruding wall 52d in the forward direction is shorter than the width dimension of the inner frame body 52c. The outdoor side surface of the protruding wall 52d is located closer to the indoor side than the outdoor side surface of the inner frame body 52c. The indoor side surface of the protruding wall 52d is located closer to the outdoor side than the indoor side surface of the inner frame body 52c.

[0026] The protrusion 52a is disposed at the lower end of the left end side of the protruding wall 52d. The protrusion 52a protrudes from the protruding wall 52d on both sides in the forward direction. The protrusions 52a are each semicircular columnar when viewed in the forward direction. The torsion coil spring 55 is attached to the outdoor protrusion 52a from the outdoor side. The engagement groove 52b is a groove recessed from the outdoor side to the indoor side of the protruding wall 52d. The engagement groove 52b extends linearly from the right end of the protruding wall 52d in the upper right direction. One spring piece 55a of the torsion coil spring 55 is inserted into the engagement groove 52b from the outdoor side. The other spring piece 55b of the torsion coil spring 55 is located to the left of the protruding wall 52d and extends linearly in the upper left direction.

[0027] The middle frame 53 is disposed on the left side of the inner frame body 52c. The middle frame 53 is disposed on the outdoor side of the lower rail portion 12b. The middle frame 53 has a pair of retaining walls 53a, a connecting wall 53b, and a connecting wall 53c. The pair of retaining walls 53a face each other with a gap in the projection direction. The protruding wall 52d is inserted from the right side into the gap between the pair of retaining walls 53a. The pair of retaining walls 53a retain the protruding wall 52d from the outside in the projection direction. The pair of retaining walls 53a each have an engagement portion 53d and a fitting hole 53e. The engagement portion 53d is provided at the upper end of the retaining wall 53a and is a surface facing the right side. The fitting hole 53e penetrates the pair of retaining walls 53a coaxially in the projection direction. The fitting hole 53e is a circular through hole when viewed in the projection direction. When the protruding wall 52d is inserted into the gap between the pair of holding walls 53a, the protrusion 52a of the inner frame 52 is inserted from the inside into the fitting hole 53e and rotatably fits into the fitting hole 53e. The middle frame 53 with the protrusion 52a inserted into the fitting hole 53e can rotate around the protrusion 52a relative to the protruding wall 52d.

[0028] The connecting wall 53b connects the pair of holding walls 53a at the right end on the upper side. The connecting wall 53c connects the pair of holding walls 53a at the left end. The other spring piece 55b of the torsion coil spring 55 engages with the connecting wall 53c from the right side. The other spring piece 55b engages with the connecting wall 53c from the right side, and the protruding wall 52d with which one spring piece 55a engages is subjected to a circumferential urging force on the side away from the other spring piece 55b with the protruding portion 52a as the center. When the door roller unit 50 is fixed to the screen door 30, the door roller 51 is applied to the inner frame 52 in a direction in which it moves downward with the protruding portion 52a as the center, and presses against the lower rail portion 12b. The connecting wall 53c has a cylindrical portion 53f extending to the left side.

[0029] The connecting wall 53c has a cylindrical portion 53f and a rectangular column portion 53g. The cylindrical portion 53f is cylindrical and extends leftward from an upper position of the connecting wall 53c. An internal thread is formed on the inner peripheral surface of the cylindrical portion 53f. The rectangular column portion 53g is rectangular and extends leftward from a position lower than the cylindrical portion 53f of the connecting wall 53c.

[0030] The outer frame 54 is disposed on the left side of the middle frame 53. The outer frame 54 is disposed on the outdoor side of the lower rail portion 12b. The outer frame 54 has a vertical wall 54a, an engagement wall 54b, and a shielding portion 54c.

[0031] The vertical wall 54a is disposed on the left side of the outer frame 54. The vertical wall 54a has a rectangular column shape extending in the up-down direction. The vertical wall 54a has a through hole 54d, a through hole 54e, and a through hole 54g.

[0032] The through-hole 54d is located on the upper side of the vertical wall 54a. The through-hole 54d penetrates the vertical wall 54a in the left-right direction. As shown in Fig. 3, an attachment screw 56 is inserted into the through-hole 54d from the left side. The door roller unit 50 is fixed to the bottom frame 12 by the attachment screw 56 inserted into the through-hole 54d.

[0033] The cylindrical portion 53f of the middle frame 53 is inserted into the through hole 54e from the right side. The adjustment screw 57 is screwed into the cylindrical portion 53f inserted into the through hole 54e from the left side. The adjustment screw 57 screwed into the cylindrical portion 53f from the left side can protrude to the right side from the connecting wall 53c of the middle frame 53. The tip of the adjustment screw 57 protruding to the right side from the connecting wall 53c is located above the protrusion 52a in the protruding wall 52d and abuts against the side surface facing the left side. The protruding wall 52d rotates around the protrusion 52a depending on the protrusion amount of the adjustment screw 57. The inner frame 52 rotates via the protruding wall 52d, causing the door roller 51 to rotate around the protrusion 52a.

[0034] As the roller 51 rotates around the protrusion 52a, the height of the screen door bottom frame 32 changes at the left-right position where the roller 51 is supported by the lower rail portion 12b. For example, when the roller 51 rotates in a direction including a component facing downward, the screen door bottom frame 32 rises at the left-right position where the roller 51 is supported by the lower rail portion 12b. For example, when the roller 51 rotates in a direction including a component facing upward, the screen door bottom frame 32 descends at the left-right position where the roller 51 is supported by the lower rail portion 12b. By adjusting the amount of screwing in of the adjustment screw 57, it is possible to adjust the height of the screen door bottom frame 32 at the left-right position of the roller 51.

[0035] The through hole 54g has a rectangular shape when viewed in the left-right direction. The rectangular column portion 53g of the inner frame 53 is inserted into the through hole 54g from the right side.

[0036] The engagement wall 54b extends to the right from the vertical wall 54a. The engagement wall 54b has a claw portion 54f at a tip thereof. The claw portion 54f engages with the engagement portion 53d of the inner frame 53 from the right side. By the claw portion 54f engaging with the engagement portion 53d from the right side, the inner frame 53 and the outer frame 54 are integrated in the left-right direction.

[0037] The shielding portion 54c is disposed at a position farther outdoors than the lower rail portion 12b. When the rolling surface 51b of the door roller 51 is supported on the upper surface of the protrusion 12c, the shielding portion 54c is formed to a size including an area overlapping with the outer shape of the water drainage opening 12d when facing the water drainage opening 12d in the forward direction as shown in Fig. 6. The shielding portion 54c is formed to a size that blocks and shields the water drainage opening 12d at a position farther outdoors.

[0038] The shielding portion 54c has a guide portion 61. The guide portion 61 is capable of coming into contact with water located in the drainage opening 12d and guiding the movement of the water. Water that comes into contact with the guide portion 61 flows downward (in the direction of falling). The guide portion 61 has a rib-shaped protrusion 62 that protrudes from the shielding portion 54c toward the indoor side. The protrusion 62 extends in a direction that includes a component facing downward. The protrusion 62 extends in the up-down direction.

[0039] The tip of the projection 62 is located on the indoor side of the shielding portion 54c. The projection 62 can engage with the lower rail portion 12b from the outdoor side when the roller 51 rolls on the upper surface of the projection 12c on the rolling surface 51b. When the roller unit 50 is in a state where the flange 51c and the projection 62 are engaged with and guided by the lower rail portion 12b from both sides in the forward direction, the rolling surface 51b can stably roll on the upper surface of the projection 12c.

[0040] The protrusion 62 has a tapered portion 62a at its tip on the indoor side. The left-right dimension of the tapered portion 62a decreases toward the indoor side. The tapered portion 62a may be an arc shape in which the left-right dimension of the protrusion 62 decreases in a curved manner toward the indoor side, as shown in Fig. 7. The tapered portion 62a may be a triangular shape in which the left-right dimension of the protrusion 62 decreases in a linear manner toward the indoor side, as shown in Fig. 8.

[0041] Because the protrusion 62 has a tapered portion 62a at its indoor tip, the frictional resistance generated when the door roller 51 rolls on the upper surface of the protrusion 12c at the rolling surface 51b and engages with the lower rail portion 12b from the outdoor side can be reduced.

[0042] As shown in FIG. 9, the water W that has accumulated on the indoor side of the lower rail portion 12b reaches the water drain opening 12d, but is stopped by surface tension. The water W that stops at the water drain opening 12d has a shape that bulges out in a cross section like an arc due to surface tension. The water W that stops at the water drain opening 12d protrudes most toward the outdoor side at the vertical center position of the water drain opening 12d. By disposing the protrusion 62 at least at the vertical center position of the water drain opening 12d, the water W that stops at the water drain opening 12d comes into contact with the protrusion 62. By coming into contact with the protrusion 62, the water W located at the water drain opening 12d is drawn into the protrusion 62 and drained from the water drain opening 12d. By extending the protrusion 62 in a direction that includes a component facing downward, the water W drained from the water drain opening 12d is guided by the protrusion 62 and flows downward by its own weight.

[0043] The protrusions 62 are arranged with gaps in the left-right direction, which is the width direction of the protrusions 62. The roller unit 50 of the embodiment has two protrusions 62. By arranging the protrusions 62 with gaps in the left-right direction, for example, if water is present in the gaps between the protrusions 62, the water located between the protrusions 62 can be drawn in when it comes into contact with the water W that stops at the water drainage opening 12d, thereby facilitating water drainage.

[0044] The protrusion 62 is disposed at least from the center position to the bottom end position of the water drainage opening 12d in the vertical direction. The top end position of the protrusion 62 shown in Fig. 9 is the top end position of the water drainage opening 12d. The bottom end position of the protrusion 62 is lower than the bottom end position of the water drainage opening 12d.

[0045] The protrusion 62 is preferably made of a resin material. Since a resin material has self-lubricating properties, by making the protrusion 62 of a resin material, it is possible to reduce frictional resistance when the protrusion 62 engages with and comes into contact with the lower rail portion 12b from the outdoor side.

[0046] In the fitting 1 of the embodiment, the shielding portion 54c blocks and shields the drainage opening 12d at a distant position on the outdoor side in the forward direction, so that the deterioration of the design can be suppressed. In the fitting 1, the guide portion 61 contacts the water W located in the drainage opening 12d and guides the movement of the water W, so that the accumulation of rainwater in the sill 12 can be suppressed.

[0047] [Second embodiment of fittings] A second embodiment of the fitting 1 of the present disclosure will be described with reference to Fig. 10. In Fig. 10, the same elements as those of the first embodiment shown in Figs. 1 to 9 are given the same reference numerals, and the description thereof will be omitted.

[0048] As shown in Fig. 10, the roller unit 50 in the fitting 1 has a roller portion 63 as a guide portion 61 on the shielding portion 54c. The roller portion 63 is provided rotatable about an axis 63a extending in the vertical direction. The roller portion 63 can roll on the lower rail portion 12b from the outdoor side at a vertical position where the outermost periphery of the roller portion 63 overlaps with the drainage opening 12d. The other configurations are the same as those of the first embodiment.

[0049] In the door roller unit 50, when the door roller 51 rolls on the upper surface of the projection 12c on the rolling surface 51b, the roller portion 63 can roll on the lower rail portion 12b from the outdoor side. In the door roller unit 50, in a state in which the flange portion 51c and the roller portion 63 are engaged with and guided by the lower rail portion 12b from both sides in the projection direction, the rolling surface 51b can stably roll on the upper surface of the projection 12c.

[0050] When the screen door 30 moves left and right via the roller unit 50 and the roller portion 63 faces the water drainage opening 12d, the water W remaining at the water drainage opening 12d comes into contact with the roller portion 63. By coming into contact with the roller portion 63, the water W located at the water drainage opening 12d is drawn into the roller portion 63 and drained from the water drainage opening 12d.

[0051] In the embodiment of the fixture 1, in addition to obtaining the same action and effect as the first embodiment, since the roller portion 63 rolls on the lower rail portion 12b from the outdoor side, it is possible to further reduce the frictional resistance when the lower rail portion 12b comes into contact with the screen door 30 from the outdoor side when the screen door 30 is opened or closed.

[0052] Although the preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to the examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.

[0053] For example, in the embodiment of the fitting 1, the upper end of the protrusion 62 is at the same height as the upper end of the water drainage opening 12d, but the present invention is not limited to this configuration. The protrusion 62 may be configured to be disposed in a range including the upper side of the upper end position and the lower side of the lower end position of the water drainage opening 12d.

[0054] By positioning the protrusion 62 in a range including above the upper end position of the water drain opening 12d and below the lower end position, even if the height of the screen door bottom frame 32 at the position of the door roller 51 in the left-right direction changes when the amount of tightening of the adjustment screw 57 is adjusted, the protrusion 62 can draw in the water W located in the water drain opening 12d and drain it from the water drain opening 12d.

[0055] In the embodiment of the fitting 1, the protrusion 62 extends in the vertical direction, but is not limited to this configuration. The protrusion 62 may extend in a diagonal direction toward the left or right as it goes downward, as long as it extends in a direction that includes a component that goes downward.

[0056] In the fitting 1 of the embodiment, a configuration in which a sliding door is used as the screen door 30 has been exemplified, but the present disclosure is not limited to this configuration. For example, the present disclosure can be applied to a fitting 1 that is not provided with a screen door 30. For example, the present disclosure may be applied to a door roller unit including a door roller 25 for the outdoor side door 20 of the door 20 described in the embodiment. [Explanation of symbols]
