Description

  The present invention relates to a sliding door device that can be configured compactly, can be easily accommodated with respect to various design conditions, and can smoothly open and close a sliding door body.

  In order to slidably support the sliding door body that opens and closes the opening, the upper rail that extends from the upper part of the opening to one side is attached to the wall, and the runner attached to the upper part of the other sliding door body can be moved to the upper rail Various suspension door support structures that suspend and support the sliding door body by engaging them have been proposed.

  For example, as shown in FIG. 11, the upper rail a having a lip groove shape is fitted and fixed to the lower end surface of the hanging wall portion b, and horizontally from the upper end portion of the support shaft e rising from the upper end portion of the other sliding door body d. The left and right wheels g, g are attached to both ends of the extending support shaft f, and the left and right wheels g, g are slidably engaged with the lip portion of the upper rail a so that the sliding door body d can be slid. Has been proposed (see, for example, Patent Document 1).

  However, the upper rail a requires a space for accommodating the supporting shaft e and the left and right wheels g, g for supporting the sliding door main body d on the inner side thereof, and also needs a supporting strength for supporting the movement of the sliding door main body d. Even if the design is devised, it must be a certain width or more. For this reason, there are cases where it cannot be installed when there are restrictions on the space, such as pillars, bearing walls, or other parts that protrude from the wall surface, or the upper rail a There is a problem that the projection itself protrudes from the wall surface and the accommodation becomes worse and the mounting strength becomes unstable.

  Therefore, as shown in FIG. 12, a single-line upper rail a comprising a mounting piece h, a hanging piece i bent downward from the mounting piece h, and a receiving part j bent in a key shape from the lower end of the hanging piece i. On the other hand, the single-wheel system which supports the sliding door main body d so that sliding is possible by engaging the wheel g of the single wheel axially attached to the angle-shaped base | substrate k fixed to the upper end surface of the sliding door main body d so that driving | running | working is possible. Has been proposed (see, for example, Patent Document 2).

  However, the sliding door body d supported by the single-wheel wheel g tends to sway and become unstable, and is difficult to slide smoothly. As a result, the operability is inferior, and vibration and noise are large when opening and closing. There is a problem of becoming. Furthermore, since the load of the sliding door main body d is supported by a single wheel, the burden on the wheel g is excessive, and trouble is likely to occur and frequent maintenance is required.

  The present invention is based on the use of an upper rail composed of a center web in the center in the width direction and left and right running flanges substantially horizontally on both sides from the lower end of the center web. It is an object to provide a sliding door device that can be mounted with good fit by clearing various constraints in the above.

  In order to achieve the above object, the sliding door device of the present invention includes a sliding door main body that opens and closes an opening, and a closed position that closes the opening and an open position that faces an adjacent wall adjacent to the opening. The sliding door support means has an upper rail that extends horizontally at the upper edge height of the opening, and a runner attached to the upper end of the sliding door body. The upper rail comprises a center web extending vertically at the center in the width direction, and left and right running flanges extending substantially horizontally from the lower end of the center web to both sides. It consists of a pair of side pieces that fold up from both sides and rises and is fixed to the sliding door main body, and is arranged inside both side pieces of the U-shaped base and is rotatably supported by the side pieces. The The left and right wheels of the runner roll on the left and right running flanges of the upper rail so that the sliding door body is supported and guided by the upper rail and moves horizontally. .

  The upper rail includes a straight portion extending parallel to the adjacent wall portion, and a slant portion that gently bends from one end portion of the straight portion and proceeds obliquely on the same horizontal plane as the straight portion, The oblique portion is continuously formed on the same side as the side where the opening portion is located with respect to the adjacent wall portion of the orthogonal portion, and may be bent in an oblique direction toward the inside of the opening portion from the open position. Alternatively, the upper rail may be provided with left and right traveling flanges extending substantially horizontally from the upper and lower ends of the center web on both sides.

  Further, the upper rail is formed by a pair of key-like bodies that are bent in an L-shaped cross section facing the inside on the upper surfaces of the left and right running flanges extending from the upper end of the center web, and are continuous along the longitudinal direction of the upper rail. A mounting recess provided with an inward lip is formed, and a mounting plate inserted in a slidable manner is screwed into the mounting recess so that the upper rail can be mounted to be adjustable in the longitudinal direction. It is also good.

  In the sliding door device of the present invention, the upper rail is composed of a center web extending vertically at the center and left and right running flanges extending substantially horizontally from the lower end of the center web to both sides. Can be formed relatively slim, and as a result, columns, bearing walls, and the like can be arranged, and can be attached to locations where the walls partially protrude, avoiding interference with the convex portions. Therefore, it is hardly influenced by the constraint condition for the mounting space of the upper rail, and can be mounted flexibly corresponding to various accommodations.

  The runner includes a U-shaped base that is fixed to the sliding door body and left and right wheels that are respectively disposed inside both side pieces of the U-shaped base. The left and right wheels are the left and right traveling flanges of the upper rail. The sliding door body is supported and guided by the upper rail by rolling up. Therefore, the load of the sliding door body is evenly supported by the left and right wheels arranged across the center line in the thickness direction of the sliding door body, so even if the door is opened and closed by abrupt push and pull, Can move horizontally. As a result, there is no hindrance to the opening and closing operation of the sliding door body, and vibration and noise due to the opening and closing movement are suppressed, making it easy to use and opening and closing openings in bedrooms, nursing homes, study rooms, etc. that require quietness Can be suitably used.

  The upper rail is supported by the upper rail when the oblique portion of the upper rail is disposed on the same side as the side where the opening is located with respect to the adjacent wall and is bent in an oblique direction from the open position toward the inside of the opening. The moving sliding door body moves horizontally in a small diagonal direction toward the inside of the opening, with horizontal movement in the direction along the adjacent wall and horizontal movement in the opening / removing direction of the opening near the closed position. The sliding door main body is inserted into the opening by a so-called swing-type opening / closing operation, and the opening can be closed without a gap. Further, the sliding door body can be continuously and smoothly moved horizontally between the open position and the closed position, reducing the force required to open and close the sliding door body and reducing noise and vibration due to the opening and closing operation. In addition, the upper rail can be opened and closed by the upper rail with a simple structure that simply provides a slanting section that is continuous in the same cross section at one end, so that the structure and construction can be simplified and trouble in use is reduced. In addition, the maintenance burden can be reduced.

  In addition, from the upper and lower ends of the center web, left and right running flanges extending in a horizontal direction on both sides are provided, and when the upper rail is formed, for example, when two types of runners are selected and used, By forming the running flange that fits the runner up and down, one type of upper rail can also be used. Furthermore, in the upper rail provided with the skewed portion at one end, if the running flange is provided at both the upper and lower ends of the center web, it can be handled by reversing the upper and lower sides and mounting it by turning it upside down. Therefore, one type of upper rail member can also be used, resulting in a reduction in the number of members.

  Further, a mounting recess provided with an inward lip is formed by a pair of key-like bodies continuous along the longitudinal direction of the upper rail, and a mounting plate inserted slidably is screwed into the mounting recess. When the upper rail is attached, the attachment position in the longitudinal direction of the upper rail can be adjusted. Particularly, since the interval between the two upper rails can be easily and precisely set, the installation adjustment of the sliding door body can be performed easily and reliably.

Further, the main wall portion 22 and the wall Wa following the main wall portion 22 can be formed as a continuous integrated structure including the base.

  The edge wall portion 23 includes a substrate portion 26 and an inclined member 27 and is continuously formed on the opening 2 side of the main wall portion 22. The substrate portion 26 is formed to be thinner than the main wall portion 22, and is arranged flush with one surface of the main wall portion 22, and a step portion 28 is formed on the other surface (side facing the sliding door body 3). . In addition, the board | substrate part 26 of this form is what was comprised using the laminated board of 3 layers which pinched | interposed the both sides of MDF (medium density fiber board) with the plywood.

  The inclined member 27 is formed with a curved surface 29 whose surface recedes closer to the opening 2 and is attached to the stepped portion 28. Further, the inclined member 27 of this embodiment is formed in a hollow shape using a curved plate such as a plastic material or a steel plate. However, an artificial wood obtained by mixing and recycling extruded wood powder with polypropylene resin, polyethylene resin, or the like is used. It may also be used to form a solid shape. Alternatively, the edge wall portion 23 may be formed by attaching an edge wall panel in which the substrate portion 26 and the inclined member 27 are integrated in advance to the opening 2 side of the main wall portion 22. Furthermore, various modifications such as using an adjacent wall panel in which the main wall 22 and the edge wall 23 are integrated in advance are possible.

  As shown in FIGS. 3 and 5, the wall Wa has an upper frame member 30 that extends horizontally along the upper edge of the opening 2 and the upper end of the adjacent wall 5 and protrudes in a bowl shape. Provided. Further, a decorative cover 31 is attached to the upper frame member 30 to cover the periphery of the upper frame member 30 and make up. In addition, the horizontal cover 32 is formed on the back surface of the decorative cover 31 of this embodiment, and the decorative cover 31 is attached by fitting the horizontal groove 32 to the upper frame member 30. In addition, frame-shaped decorative vertical frames 33A and 33B are attached to the door contact side and the door bottom side of the opening 2, respectively.

  The sliding door body 3 has a vertically long rectangular plate shape, is substantially the same height as the opening 2, and has a width slightly larger than the opening 2. Further, the sliding door body 3 of this embodiment is a flash in which a decorative board is attached to both sides of a wooden panel frame formed by extending a reinforcing bar on the inside of an outer peripheral frame in which a vertical frame material and a horizontal frame material are framed in a rectangular shape. Constructed using panels.

  As shown in FIGS. 4 and 6, the upper rail 8 has a center web 10 extending in the shape of a wall up and down at the center in the width direction, and left and right sides extending horizontally from the lower end of the center web 10 to both sides in the width direction. Traveling flanges 11 and 11 are provided. The running flange 11 is provided with an edge 46 whose side edge is slightly bent upward. Further, in this embodiment, left and right running flanges 11 and 11 extending horizontally with a small width of the same size as the above are provided on both sides in the width direction from the upper end of the center web 10, so that the upper rail 8 has a vertical cross-section in the vertical and horizontal directions. It is formed in a symmetrical E shape.

  In this embodiment, the upper surface of the running flanges 11 and 11 formed at the upper end of the center web 10 and the lower surface of the running flanges 11 and 11 formed at the lower end of the center web 10 face each other inward and have an L-shaped cross section. A pair of key-like bodies 34A, 34A that are bent along the longitudinal direction of the upper rail 8 are provided, and the opposing key-like bodies 34A, 34A form a mounting recess 34 with an inward lip 34B.

  As shown in FIGS. 2 and 3, two upper rails 8, 8 are arranged along the opening 2 and the adjacent wall 5, and are fixed to the lower surface of the upper frame member 30. In this embodiment, as shown in FIG. 6, a mounting plate 35 having a screw hole 35N is slidably inserted into the mounting recess 34, and a bolt 36 inserted from above into the upper frame member 30 is mounted on the mounting plate 35. The upper rail 8 is attached by being screwed into the screw hole 35N. Therefore, by moving the mounting plate 35 in the longitudinal direction of the upper rail 8, the mounting position facing the length direction of the upper rail 8 can be freely adjusted. In particular, the interval between the two upper rails 8 and 8 can be easily set. Moreover, since it can be performed precisely, the installation adjustment of the sliding door body 3 can be easily and reliably performed.

  The center web 10 is formed to have a height of, for example, about 15 to 50 mm, preferably 20 to 35 mm, and about 27 mm in this embodiment. The left and right running flanges 11 and 11 have a total width of, for example, about 10 to 35 mm, preferably 15 to 35 mm, and in this embodiment, about 18 mm.

  Thus, since the upper rail 8 is composed of the center web 10 and the left and right traveling flanges 11 extending from the upper and lower ends to both sides with a small width, the width can be slim. As a result, even if the wall partially protrudes, such as a pillar or a load bearing wall, it can be attached without interfering with the convex portion. Therefore, since the restriction on the mounting position of the upper rail 8 is reduced, the opening 2 can be arbitrarily arranged on the plane plan, and the sliding door main body 3 can be mounted corresponding to various accommodations.

  Further, as shown in FIGS. 2 and 4, the upper rail 8 of this embodiment includes a straight portion 16 extending in parallel to the surface direction of the adjacent wall portion 5, and an opening portion of the straight portion 16 with respect to the adjacent wall portion 5. The same side (left side in FIG. 2) as the side where 2 is located is continuously formed with a slanted portion 17 that is gently curved and bent. The oblique portion 17 is continuous with the direct portion 16 on the same horizontal plane, and bends in an oblique direction (indicated by an arrow X in FIG. 2) from the open position 6 toward the inside of the opening portion 2.

  As shown in FIGS. 6 and 7, the runner 9 includes a horizontal substrate 12, a U-shaped base 14 composed of a pair of side pieces 13, 13 bent upward from both sides thereof, and each side of the U-shaped base 14. It consists of left and right wheels 15 and 15 that are rotatably supported by the piece 13. In this embodiment, an inward support shaft 39 is provided in a cantilever manner on the side piece 13, and the wheel 15 is pivotally supported on the support shaft 39. Each side piece 13 has two wheels 15 attached thereto, and therefore the runner 9 has a total of four wheels 15.

  In the present embodiment, the U-shaped base 14 is provided with a vertically long and small block-shaped anchor 38 via a vertical axis 37 depending from the center of the substrate 12, and the anchor 38 is fitted to the upper end surface of the sliding door body 3. By doing so, the runner 9 is fixed to the sliding door body 3. The vertical axis 37 is rotatably engaged with the U-shaped base 14, whereby the runner 9 is rotatably attached to the sliding door body 3, and one piece is provided at each end of the sliding door body 3. Is placed.

  Then, as shown in FIG. 5, the left and right wheels 15 and 15 of the runner 9 attached to the upper end of the sliding door body 3 are inserted from the end of the upper rail 8 onto the left and right running flanges 11 and 11, respectively. Then, the wheel 15 rolls on the traveling flange 11 while supporting the load at both ends of the sliding door body 3. As a result, as shown in FIG. 2, the sliding door body 3 is supported and guided by the upper rail 8 between the closed position 4 where the opening 2 is closed and the open position 6 facing the adjacent wall 5. Smooth horizontal movement. In addition, the sliding door body 3 is uniformly supported by a pair of wheels 15, 15 arranged on the left and right with a center line in the thickness direction through which the center of gravity passes. Therefore, even if a sudden force is applied and the door is opened and closed roughly, the sliding door body 3 can smoothly move horizontally. Therefore, it is not only easy to use but also suppresses vibration and noise caused by the opening and closing movement of the sliding door body 3 and can be used favorably in the entrance / exit opening of bedrooms, nursing rooms, study rooms, etc. Furthermore, troubles are reduced and maintenance burden is reduced. Can be reduced.

  As described above, the upper rail 8 of the present embodiment is formed on the same side as the side where the opening 2 is located with respect to the adjacent wall 5, and the skewed portion 17 is bent in an oblique direction from the open position 6 toward the inside of the opening 2. Is done. Therefore, when the sliding door main body 3 that is supported by the upper rail 8 slides and moves to the vicinity of the closed position 4, the movement in the direction of the opening part is added to the movement in the direction along the adjacent wall part 5, and A so-called swing-type opening / closing operation is performed in which the plate moves horizontally in a small diagonal direction (indicated by an arrow X in FIG. 2) toward the inside. As a result, the sliding door body 3 is inserted inside the opening 2 so that the opening 2 can be closed without a gap, and the sliding door body 3 is smoothly moved horizontally between the open position 6 and the closed position 4. In addition, the sliding door body 3 can be opened and closed with a relatively small force, and noise and vibration associated with the opening and closing operation can be reduced. Moreover, since the upper rail 8 has a simple configuration in which one end portion is provided with a skewed portion 17 that is continuous in the same cross section, the construction can be easily performed, troubles are reduced, and maintenance is almost unnecessary.

  Further, as described above, the upper rail 8 of the present embodiment can be used upside down because the left and right traveling flanges 11 and 11 extending from both the upper and lower ends of the center web 10 are formed on both sides. . Therefore, for example, in order to support the sliding door main body 3 having different sizes, when the runners 9 of two kinds of large and small wheels 15 are selected and used, the running flanges 11 suitable for each runner 9 are formed vertically. Thus, one type of upper rail 8 can be reversed and used. Further, as in the present embodiment, in the upper rail 8 provided with the skewed portion 17 at one end, the upper rail 8 whose longitudinal section is formed in a symmetrical shape in the vertical and horizontal directions is mounted upside down, It is possible to deal with either left or right opening, and as a result, the number of members can be reduced. FIGS. 10A and 10B are a perspective view and a cross-sectional view illustrating the corresponding accommodation by attaching the same upper rail 8 in the reverse manner of FIG.

  Furthermore, in this embodiment, as shown in FIG. 2, the curved surface 29 formed on the edge wall portion 23 of the adjacent wall portion 5 eliminates interference between the operating range of the sliding door body 3 and the adjacent wall portion 5, and the sliding door body 3. The horizontal movement between the open position 6 and the closed position 4 is preferable in that the horizontal movement in the small oblique direction toward the inside of the opening 2 is possible near the closed position 4.

  In this embodiment, as shown in FIG. 1, a base board 40 continuous to the lower part of the main wall part 22 of the adjacent wall part 5 is formed, and this base board 40 continues to the lower part of the wall Wa following the main wall part 22. It extends. Further, as shown in FIG. 8, a substantially groove-shaped lower guide rail 41 that opens downward is attached to the skirting board 40. At the lower end of the other sliding door body 3, a lower pivot 43 having a lower roller 42 projecting from the side is provided, and the lower roll 42 engages with the lower guide rail 41 of the skirting board 40. The swinging in the direction perpendicular to the opening / closing direction is prevented and a smooth opening / closing movement is ensured.

  Further, as shown in FIG. 9, a door stop 44 is attached to the decorative vertical frame 33A on the door stop side of this embodiment, and receives the sliding door main body 3 and prevents light leakage. Further, an opening stopper 45 such as a sickle lock or a magnet catch is embedded in the face of the decorative vertical frame 33 facing the sliding door body 3.

  The above description is an example of the embodiment of the present invention. Therefore, the technical scope of the present invention is not limited to this, and various modifications are included in addition to the above-described embodiment.
