  The present invention relates to an anti-sway device for an upper suspension door that prevents the upper suspension door from swinging.

  Conventionally, as shown in FIG. 10A, a guide rail 31 formed with a guide groove 30 extending in the opening / closing direction of the sliding door D is fixed to the floor surface F as a swinging stop device for the upper sliding door. A device that guides the lower part of the sliding door D to prevent the sliding door D from shaking is known. Further, as shown in FIG. 10B, a guide groove 40 extending in the opening and closing direction is formed on the lower surface of the sliding door D, and the guide groove 40 is guided by the head of the guide protrusion 41 fixed to the floor surface F. What prevents sliding doors from swinging is known.

  However, in any of these guide devices, since the guide rail 31 and the guide protrusion 41 protrude from the floor surface F, the protruding portion becomes a cause of stumbling of a pedestrian and a wheelchair traffic, and the elderly and disabled persons. The response to was not enough.

  Therefore, as shown in FIG. 10C, a guide rail 50 extending in the moving direction of the sliding door D is embedded in the floor surface F, and the guide protrusion 51 fixed to the lower surface of the sliding door D is guided by the guide rail 50 to slide the sliding door. Although the thing which prevents the runout of D is proposed, the construction which embeds the guide rail 50 in the floor surface F is expensive and troublesome.

  The problem to be solved by the present invention is to provide an anti-sway device for an upper sliding door that is low in height from the floor surface and that can be easily applied to the floor surface.

  In order to solve the above-mentioned problem, a guide groove extending in the opening / closing direction of the sliding door is formed on the lower surface of the upper sliding door that opens and closes the doorway, and is continuously formed in the length direction of the guide groove on the top wall surface of the guide groove. A magnet is provided, a flat support base is fixed to the floor surface facing the lower surface of the sliding door, and a guide member that rises by suction with the magnet and fits in the guide groove is provided on the support base so as to be raised and lowered. The guide member guides the guide groove, and the guide member provides an anti-sway device for an upper sliding door that lies down at a position where the guide member is not attracted by the magnet.

This steadying device becomes more preferable when the following configuration is added.
1) The top wall surface at the end of the guide groove is a slope with a low end, and the magnet is disposed on the slope.
2) In addition to the above 1), the guide member includes a guide plate having one end rotatably connected to the support base and a magnetic plate rotatably connected to the other end of the guide plate.
3) In addition to 1) and 2) above, the guide plate is made of a magnetic material.

  The guide member lies down when it is in a position not attracted by the magnet, and the height from the floor surface is lowered, so that it does not become an obstacle to traffic. Also, the installation on the floor is easy because the support base is simply fixed to the floor.

  FIG. 1 shows an embodiment of the steady rest device of the present invention. This apparatus is attached to the upper suspension sliding door D and the floor surface F to prevent the sliding door D from swinging.

  As shown in FIG. 1, a guide groove 1 extending in the opening / closing direction of the sliding door D is formed on the lower surface of the sliding door D. The top wall surface 2L at one end of the guide groove 1 is inclined, and the terminal end 3L is a low inclined surface. A permanent magnet 5 is embedded in this slope. The formation of the inclined top wall surface 2L and the installation of the permanent magnet 5 are preferably performed by attaching the corner member 4 incorporating the permanent magnet 5 on the slope to the corner of the sliding door D as shown in the figure.

  The top wall surface 2R at the other end of the guide groove 1 is also inclined in the same manner as the top wall surface 2L, and the permanent magnet 5 is embedded in the inclined surface. An intermediate top wall 2M through the top walls 2L and 2R is horizontal, and a permanent magnet 6 extending in the length direction of the guide groove 1 is attached to the top wall 2M.

  A support base 7 is fixed to the floor surface F at a position facing the lower surface of the sliding door D, and a guide member 10 including a guide plate 8 and a magnetic plate 9 is supported on the support base 7 so as to be raised and lowered. . One end of the guide plate 8 is connected to the support base 7 so as to be rotatable about a first hinge shaft 11 which is perpendicular to the horizontal direction of the sliding door D and is horizontal. A magnetic plate 9 is coupled to the other end of the guide plate 8 so as to be rotatable about the second hinge shaft 12. As shown in FIG. 2, the width of the guide plate 8 is smaller than the width of the guide groove 1, and the leading end of the guide plate 8 that rises fits into the guide groove 1.

  The support base 7 has a flat shape in which one end of a metal plate is folded as shown in FIG. 3A, and the first hinge shaft 11 is supported by the folded portion 13. As shown in FIG. 3B, the support base 7 is preferably formed with an opening 14 penetrating vertically so that the guide plate 8 and the magnetic plate 9 can be stored in the opening 14. If it does in this way, the guide plate 8 and the magnetic plate 9 will fall down to the position of the floor surface F, and the height from the floor surface F will become smaller.

  A base cover 15 is attached to the support base 7 as shown in FIG. The base cover 15 is formed so as to cover a portion of the support base 7 excluding the opening 14 and the folded portion 13, and the increase in height from the floor F due to the mounting of the base cover 15 is minimized. Yes. Since the outer edge of the peripheral portion 15A of the base cover 15 is inclined low, the pedestrian's foot is not easily caught, and the wheelchair can be easily passed.

  Next, the operation of this steadying device will be described.

  When the sliding door D is moved, as shown in FIG. 5 (a), the guide plate 8 and the magnetic plate 9 fall down when the permanent magnets 5 and 6 do not reach the installation points of the guide plate 8 and the magnetic plate 9, respectively. However, as shown in FIG. 5B, when the permanent magnets 5 and 6 reach the installation point of the guide plate 8 and the magnetic plate 9, the guide plate 8 and the magnetic plate are attracted by the permanent magnets 5 and 6. 9 gets up.

  At this time, the permanent magnet 5 provided at the end of the guide groove 1 is at a position lower than the permanent magnet 6 provided at the intermediate part of the guide groove 1, so that the attractive force acts more strongly, and the guide plate 8 and the magnetic plate Make sure you get 9 up. When the guide plate 8 and the magnetic plate 9 are raised, the permanent magnet 6 attracts the magnetic plate 9 and holds the guide plate 8 and the magnetic plate 9 in the raised state. At this time, since the entire surface of the magnetic plate 9 is attracted to the permanent magnet 6, the permanent magnet 6 stably holds the guide plate 8 and the magnetic plate 9 in the guide groove 1. The guide plate 8 and the magnetic plate 9 thus raised are held in the guide groove 1 to prevent the sliding door D from swinging.

  When the guide plate 8 and the magnetic plate 9 reach the opposite end of the guide groove 1 as shown in FIG. 6A and further move the sliding door D, as shown in FIGS. 6B and 6C. The guide plate 8 and the magnetic plate 9 are detached from the guide groove 1 and fall down. At this time, since the top wall surface 2R at the end of the guide groove 1 has a slope with a low end 3R, the guide plate 8 and the magnetic plate 9 are forced to fall down.

  If this steady rest device is used, the guide plate 8 and the magnetic plate 9 will fall down when there is no magnet at the installation point of the guide plate 8 and the magnetic plate 9, so that the height from the floor surface F is low, and traffic obstruction Don't be. Moreover, the installation to the floor surface F is easy because it only fixes the support base 7 to the floor surface.

  It is preferable that the guide plate 8 is connected to the support base 7 so that it cannot rise up more than a predetermined angle with respect to the floor surface. If it does in this way, even if it sucks up with a vacuum cleaner, for example, the guide plate 8 will rise only to a predetermined angle, and the inversion of the guide plate 8 can be prevented. This predetermined angle is preferably set to 70 ° or less.

  The magnetic plate 9 is preferably connected to the guide plate 8 so as not to rotate downward by a predetermined angle or more with respect to the guide plate 8. In this way, when the guide plate 8 rises greatly, the tip of the magnetic plate 9 is separated from the floor surface, so that the tip of the magnetic plate 9 is not easily caught on the floor surface, and the guide plate 8 and the magnetic plate 9 are allowed to fall down. Stabilize. This predetermined angle is preferably set to 90 ° or less.

  The magnetic plate 9 is preferably connected to the guide plate 8 so as not to rotate upward by a predetermined angle or more with respect to the guide plate 8. In this way, even when the guide plate 8 and the magnetic plate 9 are lifted up by being sucked up by a vacuum cleaner, the guide plate 8 and the magnetic plate 9 stably fall to the original position due to their own weight. For example, when the guide plate 8 is connected to the support base 7 so as not to rise by 70 ° or more with respect to the floor surface, this predetermined angle is preferably set to 20 ° or less.

  A plurality of guide plates 8 and magnetic plates 9 may be arranged on the support base 7, for example, as shown in FIG. 7, two sets may be arranged side by side in the width direction of the guide groove. When two sets are attached, it can be used for sliding doors arranged in two rows as shown in FIG.

  As shown in FIG. 8A, when a plurality of support bases 7 are arranged along the opening / closing direction of the sliding door D, the support bases 7 may be arranged at an interval T shorter than the length S of the guide groove 1. If it does in this way, as shown in FIG.8 (b) and (c), even if the sliding door D exists in any position, at least 1 guide member is hold | maintained in a guide groove, and the swing of a sliding door is prevented. .

  The guide plate 8 is preferably formed of a magnetic material such as iron. In this way, as shown in FIG. 9, the permanent magnet 5 attracts not only the magnetic plate 9 but also the guide plate 8, so that the guide plate 8 and the magnetic plate 9 rise more reliably.

  The guide plate 8 and the magnetic plate 9 may be replaced with other members as long as they are raised by magnet suction and fit into the guide groove 1. For example, one end of the guide plate 8 and the magnetic plate 9 are rotatably connected to the support base 7. A movable plate incorporating a magnet at the other end may be used.

  As the permanent magnet 5, for example, a known magnet such as a ferrite magnet or a neodymium magnet can be used.

  As the permanent magnet 6, a rubber magnet extending in the length direction of the guide groove 1 or a magnet magnet brought into contact with a magnetic material extending in the length direction of the guide groove 1 can be used. A plurality of permanent magnets arranged side by side in the length direction of the guide groove 1 may be used. In short, what is necessary is just to hold the guide member 10 in the guide groove 1.

  The top wall surface of the end portion of the guide groove 1 is preferably inclined at a low end as in the above embodiment, but may be a horizontal plane without being inclined.
