Description

Technical Field

[0001] The present disclosure relates to a guide receiving member and a suspended door.

Background Art

[0002] Conventionally, when a door body suspended by a sliding door rail or the like is opened and closed, a guide device for suppressing the sway of the door body is known.

[0003] For example, the guide device of Patent Document 1 is provided on the floor surface under the track on which the door body travels, and includes a guide protrusion that can project and retract from the floor surface, a running groove provided on the lower end surface of the door body into which the guide protrusion is inserted, and a magnetic attachment means having a magnet. When the door body is opened and closed, when the magnet reaches the guide protrusion, the guide protrusion is attracted by the magnet and protrudes from the floor surface. The protruding guide protrusion engages with the running groove. When the door body is opened and closed in this state, the guide protrusion moves along the running groove. Thereby, the sway of the door body during opening and closing can be suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the magnetic attachment means of Patent Document 1, the adsorption base provided with the magnet is cantilevered in the support case so as to be swingable. Therefore, for example, since the lower end of the adsorption base protrudes below the support case, if an impact is applied to the lower surface of the protruding portion during door body construction, the adsorption base may be damaged or the adsorption base may come off the support case. Therefore, the magnetic attachment means of Patent Document 1 has room for improvement in terms of durability.

[0006] The purpose of this disclosure is to provide a guide support member and door body that constitute a sliding door and are highly durable. [Means for solving the problem]

[0007] The guide receiving member of this disclosure is provided on a sliding door and is a guide receiving member into which a guide pin, which is provided on the floor surface so as to be able to extend and retract from the floor surface, is inserted, and comprises a magnet for attracting the guide pin, a holder member to which the magnet is fixed, a case member that houses the holder member and is fixed to the sliding door, a running groove portion that extends in the opening and closing direction of the sliding door and into which the guide pin is inserted, and three or more legs provided on the lower part of the case member, wherein the holder member and the case member are fixed so as not to be able to move relative to each other, and the vertical position of the lower end of each leg portion is all less than or equal to the vertical position of the lower end of the holder member.

[0008] The door body of this disclosure is a door body that constitutes a sliding door, and comprises a sliding screen, a guide rail, and a guide receiving member of this disclosure. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0010] (First Embodiment) Hereinafter, the guide receiving member 30 of the present embodiment will be described with reference to FIGS. 1 to 9. The guide receiving member 30 is applied to the suspended door 1. The suspended door 1 is an upwardly suspended sliding door. The suspended door 1 is provided, for example, in an opening O provided in a partition wall of a building. As shown in FIG. 1, the suspended door 1 includes, for example, a door body 20 having a shoji 21. The door body 20 is suspended from an upper rail (not shown) provided along the upper edge of the opening O and is opened and closed along the direction in which the upper rail extends. [[ID=A48]]

[0011] In this specification, the "finding direction" is the direction in which the indoor side surface of the shoji 21 attached to the hanging door 1 extends. The "left - right direction" is the horizontal direction in the finding direction, which is the left - right direction when viewing the hanging door 1 from the indoor side. The "opening - closing direction" is the opening - closing direction of the shoji 21. The opening - closing direction is the left - right direction. The "prospective direction" is the indoor - outdoor direction of the hanging door 1. The prospective direction, the opening - closing direction (left - right direction), and the up - down direction are orthogonal to each other.

[0012] Also, a plurality of guide pins 10 are provided on the floor surface G. Each guide pin 10 is provided at a position overlapping the trajectory of the shoji 21 in the up - down direction during opening and closing. The number of guide pins 10 is, for example, two for one shoji 21. Each guide pin 10 is provided at an interval in the left - right direction. The interval between adjacent guide pins 10 is, for example, about 400 mm. Each guide pin 10 can protrude from and retract into the floor surface G. The part of each guide pin 10 that can protrude from and retract into the floor surface G is formed of a magnetic material such as iron. Therefore, each guide pin 10 is pulled out from the floor surface G by magnetic force. The configuration of the guide pin 10 will be described in detail later.

The indoor surface of the indoor visible wall section 33B has an indoor visible surface 35B and an indoor inclined surface 36B.

[0026] The interior facing surface 35B extends from the middle of the interior widening section 34B in the left-right direction to the left end of the interior widening section 34B. The interior facing surface 35B extends approximately parallel to the facing direction. The interior facing surface 35B faces the exterior facing surface 35A in the depth direction.

[0027] The indoor inclined surface 36B is located to the right of the indoor facing surface 35B. It extends from the right end of the indoor widening section 34B to the indoor facing surface 35B. The indoor inclined surface 36B slopes outward as it moves to the left. The indoor inclined surface 36B is inclined such that the magnitude of its slope in the left-right direction gradually decreases as it moves to the left. The indoor inclined surface 36B faces the outdoor inclined surface 36A in the depth direction.

[0028] The first visible wall portion 37 is provided between the outdoor visible wall portion 33A and the indoor visible wall portion 33B. The first visible wall portion 37 is located to the left of the right end of the case member 31. The first visible wall portion 37 extends downward from the left edge of the upper surface portion 32 to the midpoint in the vertical direction between the outdoor visible wall portion 33A and the indoor visible wall portion 33B. The first visible wall portion 37 has a substantially rectangular plate shape with its plate surface extending along the depth direction. When viewed from the right side of the case member 31, its shape is substantially U-shaped, opening downwards.

[0029] The second facade wall section 38 is provided between the exterior facade wall section 33A and the interior facade wall section 33B. The second facade wall section 38 connects the left edge of the exterior facade wall section 33A and the left edge of the interior facade wall section 33B.

The bottom surface of the second magnet M2 is nearly flush with the bottom surface of the first magnet M1. The longitudinal dimension of the second magnet M2 is larger than the longitudinal dimension of the first magnet M1.

[0041] Here, the holder member 51 and the case member 31 are fixed in a manner that prevents relative displacement.

[0042] More specifically, the holder member 51 has a first fixing portion 53 and a second fixing portion 55 that is spaced apart from the first fixing portion 53 in the left-right direction.

[0043] The first fixing parts 53 are provided in pairs in the depth direction. One of the first fixing parts 53 extends upward from the right end of the upper edge of the outer wall portion of the housing portion 52. The other of the first fixing parts 53 extends upward from the right end of the upper edge of the inner wall portion of the housing portion 52. Each of the first fixing parts 53 has a first engaging part 54. Of the first engaging parts 54, the outer first engaging part 54 has a convex shape that protrudes outwards, and the inner first engaging part 54 has a convex shape that protrudes inwards.

[0044] The second fixing parts 55 are provided in pairs in the depth direction. One of the second fixing parts 55 extends to the left from the left edge of the wall on the outdoor side of the housing part 52. The other of the first fixing parts 53 extends to the left from the left edge of the wall on the indoor side of the housing part 52. Each second fixing part 55 has a second engaging part 56. Of the second engaging parts 56, the outdoor side second engaging part 56 has a convex shape that protrudes outwards, and the indoor side second engaging part 56 has a convex shape that protrudes inwards.

[0045] Furthermore, the case member 31 has a first engaged portion 41 that engages with the first engaging portion 54, and a second engaged portion 42 that engages with the second engaging portion 56.

[0046] The first engaging portions 41 are provided in pairs in the depth direction. One of the first engaging portions 41 is provided in a position that overlaps with the first engaging portion 54 in the depth direction on the outdoor-facing wall portion 33A, and the other first engaging portion 41 is provided in a position that overlaps with the first engaging portion 54 in the depth direction on the outdoor-facing wall portion 33A. Each first engaging portion 41 penetrates the case member 31 in the depth direction, for example. The first engaging portion 54 is inserted into each first engaging portion 41. The holder member 51 and the case member 31 are connected by the first engaging portion 54 and the first engaging portions 41.

[0047] The second engaging portions 42 are provided in pairs in the depth direction. One of the second engaging portions 42 is provided in a position that overlaps with the second engaging portion 56 in the depth direction on the outdoor-facing wall portion 33A, and the other second engaging portion 42 is provided in a position that overlaps with the second engaging portion 56 in the depth direction on the outdoor-facing wall portion 33A. Each second engaging portion 42 is located to the left of each first engaging portion 41. Each second engaging portion 42 penetrates the case member 31 in the depth direction, for example. The second engaging portion 56 is inserted into each second engaging portion 42. The holder member 51 and the case member 31 are connected by the second engaging portion 56 and the second engaging portion 42.

[0048] In this case, the connection points between the holder member 51 and the case member 31 are provided in pairs in the depth direction. This suppresses the swinging of the holder member 51 in the depth direction. Multiple connection points between the holder member 51 and the case member 31 are provided at intervals in the visibility direction. This suppresses the swinging of the holder member 51 in the left-right direction. Furthermore, compared to a configuration in which the holder member 51 and the case member 31 are connected by a pair of connection points in the depth direction, the load acting on the connection points between the holder member 51 and the case member 31 can be distributed to more locations. This makes it possible to suppress damage at the connection points between the holder member 51 and the case member 31.

[0049] Furthermore, the second engaging portion 56 is provided on the opposite side of the case member 31 from the first engaging portion 54, with the left-right central portion of the case member 31 in between. The second engaged portion 42 is provided on the opposite side of the case member 31 from the first engaged portion 41, with the left-right central portion of the case member 31 in between. This makes it possible to more reliably suppress the left-right swinging of the holder member 51.

[0050] The first engaged portion 41 and the second engaged portion 42 may each be through holes or non-through holes. The relationship between the protrusions and recesses of the first engaged portion 54 and the first engaged portion 41, and the relationship between the protrusions and recesses of the second engaged portion 56 and the second engaged portion 42 may each be the opposite of the relationship described above. The first engaged portion 54 and the first engaged portion 41, and the second engaged portion 156 and the second engaged portion 42, do not necessarily have to be located on opposite sides of the central part of the case member 131 in the left-right direction.

[0051] Furthermore, when the holder member 51 is attached to the sliding door 21, the lower end of the holder member 51 is located below the lower end of the sliding door 21.

[0052] The guide support member 30 comprises three or more legs 61 provided at the lower part of the case member 31. The vertical position of the lower end of each leg 61 is all below the vertical position of the lower end of the holder member 51, and is substantially the same in detail.

[0053] More specifically, for example, four legs 61 are provided. Each leg 61 surrounds the holder member 51 when viewed in the vertical direction. The legs 61 include an outdoor first leg 62A provided on the lower surface of the outdoor visible wall 33A, with at least a portion of it located to the right of the lower end of the holder member 51; an indoor first leg 62B provided on the lower surface of the indoor visible wall 33B, with at least a portion of it located to the right of the lower end of the holder member 51; an outdoor second leg 63A provided on the lower surface of the outdoor visible wall 33A, with at least a portion located to the left of the lower end of the holder member 51; and an indoor second leg 63B provided on the lower surface of the indoor visible wall 33B, with at least a portion located to the left of the lower end of the holder member 51.

[0054] The outdoor first leg portion 62A extends, for example, from the right end of the outdoor visible wall portion 33A to the middle of the outdoor visible wall portion 33A in the left-right direction. The left end of the outdoor first leg portion 62A is positioned in the left-right direction approximately the same as the lower end of the holder member 51 in the left-right direction. The outdoor first leg portion 62A protrudes further outward than the outdoor visible wall portion 33A. The outdoor end face of the outdoor first leg portion 62A extends further outward than the outdoor visible wall portion 33A, approximately parallel to the outdoor surface of the outdoor visible wall portion 33A. The right end face of the outdoor first leg portion 62A is approximately flush with the indoor surface of the outdoor visible wall portion 33A. The indoor end face of the outdoor first leg portion 62A is approximately flush with the indoor surface of the outdoor visible wall portion 33A. The lower surface of the outdoor first leg portion 62A slopes gently downward from the right end of the outdoor first leg portion 62A toward the left, extends approximately parallel to the horizontal, and then slopes upward toward the left.

[0055] The indoor first leg portion 62B extends, for example, from the right end of the indoor visible wall portion 33B to the middle of the outdoor visible wall portion 33A in the left-right direction. The left end of the indoor first leg portion 62B is positioned in the left-right direction approximately the same as the lower end of the holder member 51 in the left-right direction. The indoor first leg portion 62B protrudes inward from the indoor visible wall portion 33B. The indoor end face of the indoor first leg portion 62B extends inward from the indoor visible wall portion 33B, approximately parallel to the indoor surface of the indoor visible wall portion 33B. The right end face of the indoor first leg portion 62B is approximately flush with the outdoor surface of the indoor visible wall portion 33B. The outdoor end face of the indoor first leg portion 62B is approximately flush with the outdoor surface of the indoor visible wall portion 33B. The lower surface of the first leg portion 62B on the interior side slopes gently downwards from the right end of the first leg portion 62B on the interior side towards the left, extends approximately parallel to the horizontal direction, and then slopes upwards as it moves further to the left.

[0056] The outdoor second leg portion 63A extends, for example, from the middle of the outdoor visible wall portion 33A in the left-right direction to the left end of the outdoor visible wall portion 33A. The left-right position of the right end of the outdoor second leg portion 63A is, for example, approximately the same as the left-right position of the center of the second magnet M2 in the left-right direction. The lower surface of the outdoor second leg portion 63A slopes downward from the right end toward the left, then extends approximately parallel to the horizontal, and then slopes upward further toward the left. The outdoor second leg portion 63A extends further outward than the outdoor visible wall portion 33A. The outdoor second leg portion 63A extends further inward than the outdoor visible wall portion 33A, and more specifically, extends further inward than the outdoor widening portion 34A. The outdoor second leg portion 63A overlaps the outdoor widening portion 34A in the vertical direction. The upper surface of the portion of the outdoor second leg portion 63A that overlaps the internal space of the running groove portion 45 in the vertical direction is inclined upward as it moves to the left.

[0057] The indoor second leg portion 63B extends, for example, from the middle of the indoor visible wall portion 33B in the left-right direction to the left end of the indoor visible wall portion 33B. The left-right position of the right end of the indoor second leg portion 63B is, for example, approximately the same as the left-right position of the center of the second magnet M2 in the left-right direction. The lower surface of the indoor second leg portion 63B slopes downward from the right end of the indoor second leg portion 63B toward the left, then extends approximately parallel to the horizontal direction, and then slopes upward toward the left. The indoor second leg portion 63B extends further inward than the indoor visible wall portion 33B. The indoor second leg portion 63B extends further outward than the indoor visible wall portion 33B, and more specifically, extends further inward than the indoor widening portion 34B. The second leg portion 63B on the interior side overlaps the widened portion 34B on the interior side in the vertical direction. The upper surface of the portion of the second leg portion 63B on the interior side that overlaps the internal space of the running groove portion 45 in the vertical direction is inclined upward as it moves to the left.

[0058] The outdoor second leg portion 63A and the indoor second leg portion 63B are provided in pairs in the direction of the groove width of the running groove portion 45 (i.e., the depth direction), with a gap narrower than the groove width of the running groove portion 45. Note that the outdoor second leg portion 63A and the indoor second leg portion 63B are sometimes collectively referred to as the "second leg portion 63". The second leg portion 63 corresponds to the guide leg portion.

[0059] The space between the outdoor second leg portion 63A and the outdoor second leg portion 63A is referred to as the "gap portion 67". The gap portion 67 overlaps with the guide groove portion 46 in the vertical direction. The center of the gap portion 67 in the depth direction overlaps with the center of the gap portion 67 in the depth direction. The depth dimension of the gap portion 67 is, for example, slightly larger than the minimum depth dimension of the part of the guide pin 10 that is retractable from the floor surface G, and slightly smaller than the maximum depth dimension of the part of the guide pin 10 that is retractable from the floor surface G.

[0060] Furthermore, the indoor surface of the outdoor second leg portion 63A has an outdoor visible surface 64A and an outdoor inclined surface 65A.

[0061] The exterior facing surface 64A extends from the middle of the exterior second leg portion 63A in the left-right direction to the left end of the exterior second leg portion 63A. The exterior facing surface 64A extends approximately parallel to the facing direction.

[0062] The outdoor inclined surface 65A is located to the right of the outdoor visible surface 64A. It extends from the right end of the outdoor second leg portion 63A to the outdoor visible surface 64A. The outdoor inclined surface 65A slopes towards the indoor side as it moves to the left. A portion of the outdoor inclined surface 65A is located on the side (more specifically, the indoor side) that is spaced further away from the center of the guide receiving member 30 in the depth direction than the case member 31.

[0063] The indoor side of the second leg portion 63B has an indoor side facing surface 64B and an indoor side inclined surface 65B.

[0064] The interior facing surface 64B extends from the middle of the interior second leg portion 63B in the left-right direction to the left end of the interior second leg portion 63B. The interior facing surface 64B extends approximately parallel to the facing direction. The interior facing surface 64B faces the exterior facing surface 64A in the depth direction.

[0065] The indoor inclined surface 65B is located to the right of the indoor visible surface 64B. It extends from the right end of the indoor second leg portion 63B to the indoor visible surface 64B. The indoor inclined surface 65B slopes outward as it moves to the left. The indoor inclined surface 65B faces the outdoor inclined surface 65A in the depth direction. A portion of the indoor inclined surface 65B is located on the side (specifically, the indoor side) that is spaced further away from the center of the guide receiving member 30 in the depth direction than the case member 31.

[0066] Of the gap 67, the space sandwiched between the outdoor-facing inclined surface 36A and the indoor-facing inclined surface 36B is defined as the "introduction section 68". The depth dimension of the introduction section 68 decreases as it moves to the left. Of the gap 67, the space sandwiched between the outdoor-facing surface 64A and the indoor-facing surface 35B is defined as the "guide section 69". The depth dimension of the guide section 69 is approximately constant throughout its entire length in the left-right direction. The depth dimension of the guide section 69 is smaller than the depth dimension of the guide section 48 of the guide groove section 46. Note that a portion of the guide section 69 is located on the side of the case member 31 that is further away from the center of the guide receiving member 30 in the depth direction.

[0067] Furthermore, the vertical position of the lower end of the outdoor first leg portion 62A, the vertical position of the lower end of the indoor first leg portion 62B, the vertical position of the lower end of the outdoor second leg portion 63A, and the vertical position of the lower end of the indoor second leg portion 63B are, for example, approximately the same. This allows the door body 20 to be stabilized when it is placed on the floor surface G.

[0068] Furthermore, if we define the direction away from the center of the running groove 45 in the groove width direction as the "outer direction in the groove width direction," the guide receiving member 30 is provided adjacent to the right side of the second leg portion 63, and includes an overhanging portion 71 that extends outward from the running groove 45 in the groove width direction, is below the running groove 45, and is above the lower surface of the adjacent second leg portion 63 in the left-right direction.

[0069] The protruding portion 71 has an outdoor protruding portion 71A and an indoor protruding portion 71B. The outdoor protruding portion 71A and the indoor protruding portion 71B are paired in the visible direction.

[0070] The outdoor overhang portion 71A is provided adjacent to the right side of the outdoor second leg portion 63A, protruding further outward than the outdoor visible wall portion 33A, and extending horizontally below the lower surface of the outdoor visible wall portion 33A and above the lower surface of the outdoor second leg portion 63A. The outdoor overhang portion 71A has a substantially flat plate shape with a plate surface extending horizontally. The outdoor overhang portion 71A is connected to the upper edge of the outdoor visible wall portion 33A. The outdoor overhang portion 71A is formed integrally with, for example, the outdoor visible wall portion 33A. The left end of the outdoor overhang portion 71A is in contact with the outdoor first leg portion 62A. The indoor end face of the outdoor overhang portion 71A is substantially flush with the indoor surface of the outdoor visible wall portion 33A. The outer end face of the outdoor overhang portion 71A extends further outward in the visible direction than the outdoor visible wall portion 33A, and the outer end face of the outdoor overhang portion 71A is substantially flush with the outer end face of the outdoor first leg portion 62A. The right end face of the outdoor overhang portion 71A slopes inward toward the interior as it moves toward the left side.

[0071] The interior overhang 71B is provided adjacent to the right side of the interior second leg portion 63B, protrudes further inward than the interior visible wall portion 33B, and extends horizontally below the lower surface of the interior visible wall portion 33B and above the lower surface of the interior second leg portion 63B. The interior overhang 71B has a substantially flat plate shape with its surface extending horizontally. The interior overhang 71B is connected to the upper edge of the interior visible wall portion 33B. The interior overhang 71B is formed integrally with, for example, the exterior visible wall portion 33A. The right end of the interior overhang 71B is in contact with the interior first leg portion 62B. The exterior end face of the interior overhang 71B is substantially flush with the exterior surface of the interior visible wall portion 33B. The indoor end face of the indoor overhang 71B extends further in the visible direction on the indoor side than the indoor visible wall portion 33B, and the outdoor end face of the indoor overhang 71B is substantially flush with the indoor end face of the indoor first leg portion 62B. The right end face of the outdoor overhang 71A slopes outward towards the left side.

[0072] The outdoor overhang portion 71A is provided at a distance from the outdoor second leg portion 63A in the left-right direction. The distance between the outdoor overhang portion 71A and the outdoor second leg portion 63A is smaller than the diameter of the head 15 of the guide pin 10, which will be described later.

[0073] The interior overhang portion 71B is provided with a gap in the left-right direction from the interior second leg portion 63B. The distance between the interior overhang portion 71B and the exterior second leg portion 63A is smaller than the diameter of the head 15 of the guide pin 10, which will be described later.

[0074] Next, the function of the guide receiving member 30 will be explained with reference to Figures 10 to 14. The guide receiving member 30 has the function of causing the guide pin 10 to protrude from the floor surface G when the door body 20 is opened and closed, and guiding the guide pin 10 into the guide rail 25 through the running groove 45.

[0075] First, let's explain the configuration of the guide pin 10 in more detail. The guide pin 10 is used in combination with a fixing member 11 that is fixed to the floor surface G.

[0076] As shown in Figures 10 and 11, each guide pin 10 includes, for example, a first member 12 held to move vertically relative to a fixing member 11 fixed to the floor surface G, a second member 13 held to move vertically relative to the first member 12, and a case 16.

[0077] The fixing member 11 is a member that houses the guide pin 10. The fixing member 11 has a fixing body portion 11a and a flange portion 11b.

[0078] The fixed main body 11a is, for example, cylindrical in shape extending vertically, and more specifically, substantially cylindrical. The floor surface G is provided with a hole that opens upward. The fixed member 11 is fitted into the hole in the floor surface G.

[0079] The flange portion 11b is provided on the upper part of the fixing member 11. The flange portion 11b protrudes horizontally from the fixing body portion 11a. The flange portion 11b is formed integrally with the fixing body portion 11a, for example. The flange portion 11b is, for example, a substantially disc shape with a surface extending horizontally. The flange portion 11b has a through hole (not shown) that penetrates the flange portion 11b vertically and through which the guide pin 10 can be inserted. The flange portion 11b rests on the floor surface G. The portion of the fixing member 11 below the flange portion 11b is located below the floor surface G. The flange portion 11b is formed relatively thinly. Therefore, the upper surface of the fixing member 11 is generally flush with the floor surface G, and more specifically, it is located slightly above the floor surface G.

[0080] The first member 12 is, for example, a long cylindrical shape extending in the vertical direction, more specifically, a long cylindrical shape. The first member 12 is housed in the case 16. The first member 12 is movable in the vertical direction relative to the case 16.

[0081] The second member 13 has an elongated shape that extends in the vertical direction. The second member 13 has a shaft portion 14 that is inserted through the first member 12 and is movable in the vertical direction, and a head portion 15 formed at the upper end of the shaft portion 14.

[0082] The shaft portion 14 passes through the first member 12. The shaft portion 14 is movable vertically relative to the first member 12. The shaft portion 14 is elongated in the vertical direction, and more specifically, it is elongated and roughly cylindrical. The outer diameter of the shaft portion 14 is smaller than the outer and inner diameters of the first member 12.

[0083] The head portion 15 is provided at the upper end of the shaft portion 14. The head portion 15 is a short columnar shape extending in the vertical direction, and more specifically, it is a short cylindrical shape. In the embodiment shown, the outer diameter of the head portion 15 is larger than the outer diameter of the shaft portion 14 and is approximately the same as the outer diameter of the first member 12, but is not limited to this. The outer diameter of the head portion 15 may be larger than the outer diameter of the first member 12.

[0084] The case 16 is fixed to the fixing member 11. The case 16 has a case fixing portion 16a that is substantially cylindrical and a flange 16b that protrudes outward from the upper end of the case fixing portion 16a. The upper end surface of the flange 16b is substantially flat. The case 16 is substantially T-shaped when viewed horizontally. The upper part of the flange 16b covers the flange portion 11b. The case fixing portion 16a is located inside the fixing member 11. A first member 12 and a second member 13 are housed inside the case fixing portion 16a. The first member 12 is movable vertically relative to the case 16. When the entire first member 12 and the entire second member 13 are housed inside the case 16, the upper end surface of the second member 13 and the upper end surface of the case 16 are substantially flush.

[0085] When fixing the guide pin 10 to the floor surface G, the fixing member 11 is first fitted into a hole formed in the floor surface G and assembled into the floor surface G. The guide pin 10 is then assembled and fixed to this fixing body 11a. More specifically, the fixing body 11a is fitted into a hole formed in the floor surface G. Next, the guide pin 10 is inserted into the fixing member 11, and the guide pin 10 and the fixing member 11 are combined. At this time, the case fixing part 16a is fitted into the fixing body 11a, and the flange 16b covers the entire flange part 11b. As a result, the guide pin 10 is attached to the floor surface G with the flange 16b covering the entire fixing member 11. With this configuration, even if the guide pin 10 is damaged, the damaged guide pin 10 can be easily replaced.

[0086] When the magnetic force of the magnet M is not acting on the guide pin 10, the entire first member 12 is housed in the fixing member 11. The entire shaft portion 14 is housed in the first member 12. The entire head portion 15 is housed in the fixing member 11. The upper end surface of the head portion 15 is substantially flush with the upper surface of the flange portion 11b. The guide pin 10 does not protrude from the fixing member 11 when there is no guide receiving member 30 nearby and the guide is not guided by the guide rail 25. Therefore, with such a guide pin 10, for example, when the sliding door 1 is open, the floor surface G can be made closer to flat.

[0087] Next, the behavior of the guide pin 10 when the door 20 is opened and closed will be explained with reference to Figures 12 to 14.

[0088] As shown in Figure 12, as the door body 20 moves to the right, the right-side guide receiving member 30 and the guide pin 10 overlap vertically. First, the part of the guide receiving member 30 to the right of the magnet M and the guide pin 10 overlap vertically. At this stage, the magnetic force of the magnet M has not yet fully acted on the guide pin 10, so the guide pin 10 does not protrude from the fixing member 11.

[0089] As shown in Figure 13, as the door 20 moves further to the right, the first magnet M1 and the guide pin 10 overlap in the vertical direction. The magnetic force of the first magnet M1 acts on the guide pin 10. The second member 13 is attracted to the first magnet M1 and protrudes from the floor surface G. The upper end of the guide pin 10 is introduced into the running groove 45. The upper end of the guide pin 10 abuts against the lower surface of the holder member 51. The lower surface of the holder member 51 is inclined upward as it moves to the left. Therefore, as the door 20 moves to the right, the second member 13 gradually protrudes. It is desirable that the magnetic force of the first magnet M1 be set to be stronger than that of the second magnet M2. However, it is not limited to this, and the first magnet M1 only needs to have enough magnetic force to attract and hold the head 15 of the guide pin 10 provided on the floor surface G when the door 20 is opened and closed.

[0090] As shown in Figure 14, as the door 20 moves further to the right, the second magnet M2 and the guide pin 10 overlap in the vertical direction. The magnetic force of the second magnet M2 acts on the guide pin 10. The guide pin 10 is attracted to the second magnet M2 and protrudes further from the floor surface G. The upper end of the guide pin 10 comes into contact with the lower surface of the holder member 51. The lower surface of the holder member 51 is inclined upward as it moves to the left. Therefore, as the door 20 moves to the right, the second member 13 gradually protrudes. Although not shown, as the door 20 moves further to the right, the first member 12 is also attracted to the magnet M2 and gradually protrudes from the floor surface G. It is desirable that the magnetic force of the second magnet M2 be set weaker than that of the first magnet M1. However, it is not limited to this, and the second magnet M2 only needs to have enough magnetic force to prevent the guide pin 10 from falling off while the second magnet M2 is moving directly above the guide pin 10.

[0091] The head 15 of the guide pin 10 is pulled up above the second leg portion 63 just before the guide pin 10 overlaps the guide groove portion 46 in the vertical direction. In this state, as the door body 20 moves further to the right, the guide pin 10 is introduced into the guide groove portion 46. An introduction portion 47 is formed at the right end of the guide groove portion 46. This makes it easier to introduce the guide pin 10 into the guide groove portion 46. After that, the guide pin 10 slides along the guide groove portion 46 with the head 15 of the guide pin 10 and the second leg portion 63 engaged. This suppresses the vibration of the door body 20 when it is opened and closed. In addition, the guide pin 10 moves inside the gap portion 67 while sliding against the second leg portion 63. This further suppresses the vibration of the door body 20 when it is opened and closed.

[0092] Furthermore, if the door body 20 swings in the forward direction while the guide pin 10 is protruding, there is a risk that the guide pin 10 will not be introduced into the running groove 45. However, the guide receiving member 30 is provided with an overhanging portion 71. Therefore, if the guide pin 10 protrudes slightly away from the inside of the running groove 45, the upper end of the guide pin 10 will come into contact with the overhanging portion 71. In this state, when the guide pin 10 is attracted by the magnet M, the guide pin 10 is pulled towards the inside of the running groove 45. This ensures that the guide pin 10 is reliably introduced into the running groove 45.

[0093] Furthermore, the second leg portion 63 is provided to protrude outward in the groove width direction from the running groove portion 45. The right end face of the second leg portion 63 is inclined so that it approaches the center of the guide receiving member 30 in the depth direction as it moves to the left. Therefore, as the door body 20 moves to the right, the guide pin 10 that is in contact with the protruding portion 71 comes into contact with the right end face of the second leg portion 63. The guide pin 10 moves along the right end face of the second leg portion 63 and is introduced into the guide groove portion 46. This ensures that the guide pin 10 is reliably introduced into the guide groove portion 46.

[0094] Furthermore, the distance between the protruding portion 71 and the second leg portion 63 is smaller than the maximum diameter of the head 15 of the guide pin 10. This prevents the guide pin 10 from getting stuck between the protruding portion 71 and the second leg portion 63.

[0095] Although not shown in the diagram, as the door 20 moves further to the right, the guide pin 10 is introduced into the guide rail 25 through the guide groove 46. The guide pin 10 slides against the guide rail 25. This suppresses the swaying of the door 20 when it is opened and closed.

[0096] <Effects according to the first embodiment> The guide receiving member 30 and door body 20 of this embodiment provide the following advantages.

[0097] The guide receiving member 30 is provided on the sliding screen 21 that constitutes the sliding door 1, and is a guide receiving member into which a guide pin 10, which is provided on the floor surface G so as to be able to extend and retract from the floor surface G, is inserted. It comprises a magnet M that attracts the guide pin 10, a holder member 51 to which the magnet M is fixed, a case member 31 that houses the holder member 51 and is fixed to the sliding screen 21, a running groove 45 that extends in the opening and closing direction of the sliding door 1 into which the guide pin 10 is inserted, and three or more (specifically four) legs 61 provided on the lower part of the case member 31. The holder member 51 and the case member 31 are fixed so as not to be able to move relative to each other. The vertical position of the lower end of each leg 61 is all below the vertical position of the lower end of the holder member 51.

[0098] In this configuration, the holder member 51 and the case member 31 are fixed so that they cannot be displaced relative to each other. Therefore, compared to a configuration in which the holder member 51 is cantilevered to the case member 31 so as to be able to swing in the left-right direction, it is easier to provide more connection points between the holder member 51 and the case member 31, and to create a more robust configuration. This makes it possible to suppress the occurrence of malfunctions at the connection points between the holder member 51 and the case member 31.

[0099] On the other hand, for example, when hanging the shoji screen 21, it is assumed that the shoji screen 21, which is equipped with a guide receiving member 30, may be temporarily placed on the floor surface G. In this case, if the holder member 51 and the case member 31 are fixed so that they cannot be displaced relative to each other, it is thought that a load will be placed on the holder member 51 when the holder member 51 comes into contact with the floor surface G. However, there are three or more legs 61, and the vertical position of the lower end of each leg 61 is all below the vertical position of the lower end of the holder member 51. This makes it possible to suppress the load placed on the holder member 51 due to contact between the holder member 51 and the floor surface G.

[0100] Therefore, it is possible to provide a guide support member 30 that is a guide support member for a sliding door and has excellent durability.

[0101] Each of the multiple legs 61 has a second leg 63 that is provided in pairs in the direction of the running groove 45's groove width (more specifically, the depth direction) at intervals narrower than the groove width of the running groove 45.

[0102] With this configuration, the swaying of the shoji screen 21 can be effectively suppressed by passing the guide pin 10 through the space between the second legs 63 (i.e., the gap 67).

[0103] The indoor surface of the outdoor second leg portion 63A has an outdoor inclined surface 65A that slopes inward towards the indoor side as it moves from right to left. The outdoor surface of the indoor second leg portion 63B has an indoor inclined surface 65B that slopes inward towards the outdoor side as it moves from right to left.

[0104] With this configuration, the inlet side of the gap 67 can be made wider than the outlet side, making it easier to introduce the guide pin 10 into the gap 67.

[0105] The guide support member 30 is provided adjacent to the right side of the outdoor second leg portion 63A and includes an outdoor overhang portion 71A that extends outward from the running groove portion 45, is below the running groove portion 45 and above the outdoor second leg portion 63A, and an indoor overhang portion 71B that is provided adjacent to the right side of the indoor second leg portion 63B and extends inward from the running groove portion 45, is below the running groove portion 45 and above the indoor second leg portion 63B, and

[0106] If the door body 20 swings in the forward direction while the guide pin 10 is protruding, there is a risk that the guide pin 10 will not be introduced into the running groove 45. However, with this configuration, if the guide pin 10 protrudes slightly away from the inside of the running groove 45, the upper end of the guide pin 10 will come into contact with the protruding portion 71. When the door body 20 moves to the left while the guide pin 10 is in contact with the protruding portion 71, the guide pin 10 will come into contact with the inclined surface 65 and be guided into the gap 67. This ensures that the guide pin 10 is reliably introduced into the running groove 45.

[0107] The outdoor overhang portion 71A is provided at a distance from the outdoor second leg portion 63A. The indoor overhang portion 71B is provided at a distance from the indoor second leg portion.

[0108] For example, if the protruding portion 71 and the second leg portion 63 are in contact, a corner may be formed between the protruding portion 71 and the second leg portion 63, and dust and other debris may accumulate in that corner. In that case, the guide pin 10 may come into contact with the accumulated dust and other debris, and the trajectory of the guide pin 10 may be misaligned. Alternatively, if the dust and other debris adhere to the head of the guide pin 10, it may affect the magnetic attraction of the guide pin 10. However, with this configuration, the formation of a corner between the protruding portion 71 and the second leg portion 63 can be suppressed, thereby suppressing misalignment of the trajectory of the guide pin 10 and preventing insufficient attraction between the magnet M and the guide pin 10. As a result, the guide pin 10 can be guided more reliably into the gap portion 67.

[0109] The door body 20 is a door body that constitutes the sliding door 1, and comprises a sliding screen 21, a guide rail 25 provided at the lower part of the sliding screen 21, and a guide receiving member 30.

[0110] With this configuration, the durability of the guide receiving member 30 portion of the door body 20 can be increased, thus providing a door body 20 that constitutes a sliding door and has excellent durability.

[0111] The lower end of the holder member 51 is located below the lower end of the sliding door 21.

[0112] With this configuration, the magnet M can be brought closer to the floor surface, making it easier to increase the attraction efficiency when the magnet M attracts the guide pin 10. This makes it possible to pull the guide pin 10 out more reliably from the floor surface G and to introduce the guide pin 10 more reliably into the guide receiving member 30. Furthermore, with the guide receiving member 30, the vertical position of the lower end of each leg portion 61 is always below the vertical position of the lower end of the holder member 51. Therefore, even in a configuration where the lower end of the holder member 51 is located below the lower end of the sliding door 21, the lower end of the holder member 51 is protected from collision by each leg portion 61. Thus, it is possible to provide a door body with excellent running stability during opening and closing and excellent durability of the holder member 51.

[0113] Furthermore, since the guide receiving member 30 can function fully with less magnetic force, the cost of magnets can be reduced.

[0114] <Second Embodiment> Next, a second embodiment of this disclosure will be described with reference to Figures 15 to 21. The explanation will focus on the differences from the first embodiment. Components similar to those in the first embodiment may be denoted by the same reference numerals and their description may be omitted.

[0115] As shown in Figures 15 to 21, in the guide receiving member 130 of the second embodiment, the protruding portion 171 constitutes a part of the holder member 151. In other words, in the second embodiment, the holder member 151 has the protruding portion 171. The case member 131 of the guide receiving member 130 does not have a protruding portion.

[0116] The protruding portion 171 has an outdoor protruding portion 171A and an indoor protruding portion 171B.

[0117] The outdoor overhang portion 171A is provided on the lower edge of the housing portion 52 of the holder member 151. The outdoor overhang portion 171A extends outward from the housing portion 52. The outdoor overhang portion 171A extends further outward than the outdoor visible wall portion 33A. The outdoor overhang portion 171A extends in the left-right direction below the lower surface of the outdoor visible wall portion 33A and above the lower surface of the outdoor second leg portion 63A.

[0118] The interior overhang portion 171B is provided on the lower edge of the housing portion 52 of the holder member 151. The interior overhang portion 171B extends inward from the housing portion 52. The interior overhang portion 171B extends further inward than the interior visible wall portion 33B. The interior overhang portion 171B extends in the left-right direction below the lower surface of the interior visible wall portion 33B and above the lower surface of the interior second leg portion 63B.

[0119] Because the protruding portion 171 is formed relatively thinly, it may break if it collides strongly with an object. If the protruding portion 171 constitutes part of the case member 131, then when the protruding portion 171 is damaged, it may be possible to replace the case member 131 with a new one. However, since the case member 131 is fixed to the shoji screen 21, the effort required to replace the case member 131 is considered to be relatively large. With this configuration, if the protruding portion 171 is damaged, the guide receiving member 130 can be repaired by replacing the holder member 151. This makes it easier to repair the guide receiving member 130.

[0120] Furthermore, the lower edge of the case member 131 is provided with a notch 181 that is concave upwards. The left-right position of the notch 181 coincides with the left-right position of the space between the protruding portion 171 and the second leg portion 63. The internal space of the notch 181, when viewed in the depth direction, coincides with the holder member 151 (more specifically, the housing portion 52).

[0121] The notch 181 has an outdoor notch 181A and an indoor notch 181B.

[0122] The outdoor-side notch 181A is provided at the lower edge of the outdoor-side visible wall portion 33A. The outdoor-side notch 181A is formed by cutting out the lower edge of the outdoor-side notch 181A toward the upward. The internal space of the outdoor-side notch 181A is in communication with the space between the outdoor-side overhang portion 171A and the outdoor-side second leg portion 63A.

[0123] The indoor notch 181B is provided at the lower edge of the indoor visible wall portion 33B. The indoor notch 181B is formed by cutting out the lower edge of the indoor notch 181B upwards. The internal space of the indoor notch 181B is in communication with the space between the indoor overhang portion 171B and the indoor second leg portion 63B.

[0124] In the second embodiment, the second engaging portion 156 is provided in the housing portion 52 instead of the second fixing portion 55. In the second embodiment, the second engaged portion 42 is provided near the left-right center of the case member 131. The first engaging portion 54 and the first engaged portion 41 and the second engaging portion 156 and the second engaged portion 42 do not necessarily have to be provided on opposite sides of the left-right center of the case member 131.

Various modifications and changes that do not depart from the gist of this disclosure are included herein.

[0126] The configuration of the connection point between the holder member 51 and the case member 31 is not limited to those of the embodiments described above. For example, one of the holder member 51 and the case member 31 may be provided with a projection extending in the visible direction, and the other may be provided with a slit extending in the visible direction into which the projection is inserted. Such a configuration can also suppress the concentration of load at the connection point between the holder member 51 and the case member 31. Furthermore, the manner in which the holder member 51 and the case member 31 are fixed is not limited to fitting and fixing, but may be, for example, screw fastening.
