Description

  The present invention relates to a suspension device for a hanging sliding door. More particularly, the present invention relates to a swing-proof device for a hanging type sliding door that can effectively prevent the swinging of the sliding door and that has a flat floor when the sliding door is opened.

  Various sliding doors are used for partitioning large rooms and opening / closing the entrances of rooms. Usually, in the case of a sliding door that slides on the floor, a sill is provided to guide the sliding door along a predetermined direction, or a rail or a groove is provided on a floor board, etc. There is a possibility that it may hinder the crossing of people and carts, which is not preferable from the viewpoint of barrier-free.

  Therefore, in recent years, a hanging type sliding door is used in which the sliding door is suspended from a rail provided in a room or a ceiling of the room, and the sliding door is slid in a state slightly separated from the floor.

  In the suspension type sliding door, since the lower end of the sliding door is not restrained, a swing stopper is required to prevent the sliding door from swinging. However, if the brace remains protruding from the floor, it becomes an obstacle to traffic and the advantage of the hanging type is impaired. Therefore, conventionally, a traveling guide for a suspended door has been proposed in which a guide pin submerged on the floor surface side is pulled up by a magnet provided on the suspended door side so as to be projected and guided. For example, in Patent Document 1, a guide pin is a structure in which a piston-like guide pin moves up and down in a cylindrical outer case.

JP 2001-65228 A

  The suspension type sliding door has a problem that it is easy to swing because the lower end is not constrained and is generally lighter than a sliding door that slides on the floor. Therefore, there is a problem that the user's body easily shakes only by lightly hitting the sliding door. In order to prevent the swinging of the sliding door, it is possible to lock the pin attached to the sliding door in the hole or groove formed in the floor. In this case, it is necessary to form a hole or groove in the floor. In addition, holes or grooves formed in the floor have a problem that dust and dust are likely to collect.

  On the other hand, swinging of the sliding door can be prevented by protruding a pin or protrusion from the floor and inserting the pin or protrusion into the groove formed on the lower end surface of the sliding door. Since the pins and protrusions protrude from the door, it will hinder the passage of people.

  There is a traveling guide of a hanging door that guides traveling by pulling up a guide pin sunk on the floor side with a magnet provided on the hanging door side as in Patent Document 1, but there is no hanging door In order for the pin not to protrude from the floor, a hole longer than the length of the pin must be formed in the floor.

  The present invention has been made to solve such a problem, and can effectively prevent the swinging of the sliding door. When the sliding door is opened, the floor becomes flat and can be easily attached to the floor. An object of the present invention is to provide an anti-rest device for a hanging sliding door.

In a four-ply hanging type sliding door, four door plates S1 to S4 are suspended slidably via a roller or the like with respect to a rail provided on the ceiling of the room or a duck. The steady rest device of the present embodiment is provided on the lower end surface and floor surface of the four door plates S1 to S4.

  As shown in FIGS. 3 to 9, the steady rest device of the present embodiment includes a pedestal 1 fixed to the floor, and a swing plate made of a magnetic body that is swingably attached to the pedestal 1 in the vertical direction. 2 and the rail 3 fixed to the lower edge of each of the door plates S1 to S4 and guiding the engaging portion 6 of the swing plate 2 along the lower edge of each of the door plates S1 to S4, and each of the door plates S1 to S4 An end guide 4 connected to both ends of the rail 3 and the engaging portion 6 of the swinging plate 2 to a position where the engaging portion 6 engages with the rail 3, and fixed to the end guide 4. The magnet 5 is configured to attract the swing plate 2 toward the end guide 4.

  As shown in FIGS. 4 and 5, the pedestal 1 is formed of a thin metal plate having a thickness that does not protrude from the floor surface, for example, a thickness of about 3 mm, and the thickness decreases toward the periphery. Therefore, it can be attached without making a hole in the floor surface, and a smooth flat surface is formed substantially together with the floor surface. As a result, it does not hinder the passage of people and carts.

  The rocking plate 2 is made of a thin plate made of a magnetic material such as iron or steel, and a pair of engaging portions 6 extending in a direction substantially perpendicular to the longitudinal direction of the rocking plate 2 project from the tip portion. Yes. In addition, a pair of rotating shafts 7 that extend in a direction substantially perpendicular to the longitudinal direction of the rocking plate 2 are projected from the base side end of the rocking plate 2. The swing plate 2 is inserted into the substantially rectangular slit 8 of the base 1 from below, and the rotating shaft 7 is inserted into a bearing recess 9 formed on the lower surface side of the base 1. Further, a presser plate 10 is fixed to the lower surface of the pedestal 1 so that the rotating shaft 7 does not fall out of the bearing recess 9. With this configuration, the swing plate 2 is supported so as to be swingable in the vertical direction inside the slit 8 of the base 1. As shown in FIGS. 4 to 5, in the state where the swing plate 2 lies substantially horizontally, a smooth flat surface is formed together with the pedestal 1, so that the passage is not hindered as described above.

  Moreover, in order to absorb the impact at the time of a collision with a floor surface and the rail 3, it is preferable to provide buffer bodies, such as a rubber sheet, for example in the upper surface and lower surface of the front-end | tip part of the rocking plate 2. FIG.

  As shown in FIGS. 1 and 2, the floor-side portions 21 to 28 including the base 1 and the swing plate 2 are engaged with the rail 3 when the door plates S1 to S4 are fully opened or fully closed. It arrange | positions in the vicinity of the pillar P or the center of an entrance so that it may match. For example, as shown in FIG. 2, the swing plate 2 is set so that the tip portion faces the column P or the center of the entrance.

  In addition, although not illustrated, in order to further eliminate the swing of each door plate S1 to S4, between the floor side portions 21 and 22, between the floor side portions 23 and 24, and the floor side portions 25 and 26, Between the floor side portions 27 and 28, a floor side portion having the same configuration may be disposed.

  In the present embodiment, as the movable member, the swing plate attached to the base so as to be swingable in the vertical direction has been described as an example, but the present invention is not limited to this, and the base is not limited to this. Various movable members can be used as long as they are movable in the vertical direction, at least a part thereof is made of a magnetic material, and a distal end portion is provided with an engaging portion projecting in a direction substantially perpendicular to the longitudinal direction of the movable member. The movable member of the aspect can be employed.

  For example, as another movable member, a wire rod or a thin bar made of a magnetic material in which an engaging portion is formed by processing the tip portion into a substantially L shape or T shape instead of a plate-like member. May be. As another movable member, when a part of the pedestal can be embedded in the floor, a plate-like engaging portion made of a magnetic material is fixed to the tip of a cylinder that can be moved up and down in the vertical direction on the pedestal. A vertically movable movable member or the like formed as described above can also be employed as the movable member of the present invention.

  Further, if a part of the movable member such as the swing plate 2 is formed of a magnet, the movable member can be made stronger by the action of the magnetic force of both the magnet 5 on the end guide 4 side and the magnet on the movable member side. It is possible to suck strongly toward the end guide. As a result, the movable member can be reliably guided to the rail via the end guide, and can react even if the gap between the floor and the bottom surface of the door plate becomes wide. In addition, by providing a magnet in the vicinity of the tip of the swing plate 2, a magnetic body can be employed instead of the magnet 5 on the end guide 4 side.

  The rail 3 is embed | buried in the groove | channel G formed in the lower end edge of each doorplate S1-S4 as FIG. The rail 3 is composed of a long hollow body that opens downward, and has a pair of horizontal ribs 11 that extend in the horizontal direction and engage with the pair of engaging portions 6 of the swing plate 2. The distance between the tips of the pair of horizontal ribs 11 is substantially equal to the width of the swing plate 2. The engaging portion 6 of the swing plate 2 guided into the rail 3 by the end guide 4 described later engages with the horizontal rib 11 of the rail 3 and along the lower edge of the door plates S1 to S4 by the rail 3. Guided.

  As shown in FIG. 3, the cross-sectional shape of the rail 3 has a space 3a that can be fitted with a pair of fitting protrusions 12 (see FIGS. 6 to 7) provided on the end guide 4. Therefore, even if the rail 3 is cut at an arbitrary length, the rail 3 can always be connected to the end guide 4. Thereby, the rail 3 and the end guide 4 can be attached in accordance with the width of the door plate. For example, in the case of door plates S1 to S4 shown in FIG. 2, each door plate has two end guides 4 and rails 3, but the length of the two end guides 4 is determined from the width of the door plate. If the rail is cut to the subtracted length and then the end guide 4 is connected to both ends of the rail 3, the total length of the rail 3 and the end guide 4 can be easily adjusted to the width of the door plate. it can. The rail 3 and the end guide 4 are fixed to the inside of the groove at the lower edge of the door plate by a method such as adhesion or fastening with a wood screw.

  As shown in FIGS. 6 to 9, the end guide 4 is formed of a hollow body opened downward, and a magnet 5 is fixed to the upper surface side, and a pair of engagement of the swing plate 2 is disposed on the bottom surface side. A pair of guide ribs 13 extending in the horizontal direction and engaged with the portion 6 are provided. The guide rib 13 is partially formed in the vicinity of the fitting protrusion 12 connected to the rail 3 (see FIGS. 7 and 9), and the width of the guide rib 13 gradually decreases toward the opposite end, The guide ribs 13 are formed in the middle portion of the fitting protrusion 12 so as to disappear. Thereby, after the engaging portion 6 of the swing plate 2 is drawn toward the bottom surface 14 of the end guide 4 by the magnetic force of the magnet 5, the guide rib 13 is smoothly guided while being guided by the inclined surface 13a of the guide rib 13. And then guided to the rail 3.

  Further, as shown in FIGS. 6 and 8, on the upper surface side of the end guide 4, at least one claw for locking the magnet 5 to a predetermined fixing position in the end guide 4, In the form, four claws 15 are formed. A contact surface 15a (see FIG. 8) is formed at the tip of the claw 15 to prevent the magnet from falling off by making surface contact with the magnet 5 locked at a predetermined fixing position. Therefore, for example, if the magnet 5 is fitted to a predetermined fixing position surrounded by the four claws 15 in FIG. Nothing will happen.

  Note that the end guide and the rail are not necessarily separated from each other. When the dimensions of the door plate are fixed in advance, the end guide is integrally formed with the rail so as to match the dimensions of the door plate. Also good.

  For example, a rectangular permanent magnet that has been commercially available can be adopted as the magnet 5. However, in the present invention, various conditions such as the size and performance of the magnet are not particularly limited.

  In the present embodiment, an example in which the magnet 5 is fixed to the end guide 4 is shown, but the present invention is not limited to this, and the magnet is disposed in a position close to the end guide. Then, the movable member can be protruded from the floor near the end guide. Therefore, you may attach to the side edge surface vicinity of a doorplate instead of adhering a magnet to an edge part guide.

  In the anti-seismic device of the present embodiment configured as described above, the swing plate 2 is automatically engaged with the rail 3 using the magnetic force of the magnet 5 when the door plates S1 to S4 are fully opened or fully closed. Can be combined.

  For example, when the door plate S2 shown in FIG. 10A slides toward the floor side portion 22 composed of the base 1 and the swinging plate 2 provided near the entrance center (that is, in the closing direction). When the distance between the end guide 4 and the floor side portion 22 is long, the rocking plate 2 lies horizontally, so that the floor surface is flat.

  Then, as shown in FIG. 10B, when the door plate S <b> 2 advances and the end guide 4 moves to substantially above the floor side portion 22, the magnet 5 of the end guide 4 moves the swing plate 2. Aspirate and protrude.

  Further, as shown in FIG. 10 (c), when the door plate S2 is advanced, the guide rib 13 (see FIGS. 7 and 9) of the end guide 4 is moved to the engaging portion 6 (see FIG. 7) of the swing plate 2. 4-5) is guided to the inside of the rail 3, and when the door plate S2 comes to a predetermined fully closed position in the center of the entrance, the engaging portion 6 of the swing plate 2 is engaged with the rail 3, and the door plate S2 swings. Can be prevented (see FIGS. 1 to 3).

  Although the door plate S2 shown in FIG. 10C is prohibited from swinging by the swing plate 2, the swing plate 2 is slidable inside the rail 3, so that it can slide both forward and backward. . Accordingly, the four door plates S1 to S4 shown in FIGS. 1 and 2 can be moved toward any one of the pillars P beyond the center of the entrance.

  When the engagement between the engaging portion 6 of the swing plate 2 and the rail 3 is released, the engaging portion 6 is moved to the rail 3 and the door plate S2 only by sliding in the forward or backward direction. It can be easily extracted from the end guide 4. At that time, the swinging plate 2 whose attracting force by the magnet 5 has weakened falls again horizontally due to its own weight, and the floor surface becomes almost flat.

Embodiment 2
FIG. 11 is a partial cross-sectional perspective view of the anti-vibration device according to Embodiment 2 of the present invention.
In the second embodiment, the pedestal and the movable member are embedded in the floor surface so that the upper surface of the pedestal is flush with the floor surface. The upper surface of the pedestal is flat, and an arbitrary cross-sectional shape parallel to the upper surface of the pedestal is within the range of the upper surface outline. The pedestal having such a shape is embedded in the floor so that the upper surface is flush with the floor. Since the upper surface of the pedestal is flat, when the upper surface of the pedestal is embedded in the same plane as the floor surface, the floor surface becomes flat. In addition, since any cross-sectional shape parallel to the upper surface of the pedestal is within the range of the upper surface of the pedestal, when embedding the pedestal on the floor surface, a hole having the size of the upper surface of the pedestal may be formed. I don't get angry. Therefore, even if it passes, it does not hinder at all, and even if it temporarily places things on the floor, it does not hinder it.
