Description

  The present invention relates to a stopper for stopping an outset sliding door, and more particularly to a stopper for an outset sliding door that is used by being mounted on the bottom and floor of the sliding door.

  Outset sliding doors are becoming popular as external sliding doors that can be constructed relatively easily in room renovation and the like. This type of outset sliding door is generally installed at the end of the rail when it is closed or opened because the roller engaged on the upper rail rotates and travels very lightly and vigorously. There was a problem that the sliding doors hit the stoppers vigorously and bounced back, making it easy to open halfway.

Therefore, conventionally, in Patent Document 1 and the like below, a stopper has been proposed in which when the outset sliding door hits the end of the rail, the sliding door is stopped by suppressing rebound.
JP 2002-349125 A

  However, since this type of conventional outset sliding door stopper is usually attached to the upper rail and applied to a roller running on the rail, or stopped against the sliding door support frame, the lower part of the sliding door is There was a problem that the lower part of the sliding door swings in an unstable manner.

  This invention solves the above-mentioned subject, and it aims at providing the stopper for outset sliding doors which can prevent the rebound at the time of a stop of an outset sliding door, and the shake | fluctuation of a lower part.

  In order to achieve the above object, an outset sliding door stopper according to the present invention includes a stopper holder attached to the bottom of the outset sliding door, and a stopper attached on the floor directly below the outset sliding door. A stopper member that can be attracted to the magnet is pivotally supported so that it can be tilted upward from the horizontal position, and the magnet can swing according to the attracting action of the stopper member. It is attached to.

  Here, as in claim 2, the stopper member of the stopper can be disposed so as to be inclined and rotated in a vertical plane along the traveling direction of the outset sliding door.

  According to a third aspect of the present invention, the magnet of the stopper holder is housed in a magnet case, the magnet case is pivotally supported via a swing shaft, and the swing surface of the magnet case is a stopper member. The magnet case and the stopper member can be tilted so that the magnet attracting surface coincides with the attracting surface of the stopper member.

  The stopper for an outset sliding door having the above configuration is used with a stopper holder attached to the bottom of the outset sliding door and a stopper attached to the floor directly below the outset sliding door. When the outset sliding door runs on the rail and the stopper holder at the bottom of the sliding door reaches the stopper, when the sliding door stops by hitting the stopper on the rail, the stopper member of the stopper on the floor is provided at the bottom of the sliding door It is attracted by the magnet of the stopper holder and tilted upward and is attracted to the magnet. Thereby, the upper part and the lower part of the outset sliding door are reliably stopped by the stopper, the rebounding at the time of stopping is prevented, the swing of the lower part of the sliding door is prevented, and the sliding door can be stably stopped. In addition, since the stopper member is pivotally supported so as to be tilted and the magnet is swingably attached, even when the gap between the sliding door and the floor surface changes, the stopper member is caused to follow the magnet and be favorably attracted. be able to.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of an outset sliding door stopper. The stopper for the outset sliding door includes a stopper 1 attached on the floor and a stopper receiving member 2 attached to the bottom of the outset sliding door 3.

  As shown in FIGS. 1, 6, and 7, the stopper 1 includes a mounting plate 11 as a base, and a stopper member 12 made of a metal plate is pivotally supported in a central opening of the mounting plate 11. Formed. As shown in FIG. 7, the mounting plate 11 includes a base plate 11a formed of a metal plate and a synthetic resin cover 11b. The base plate 11a has a rectangular opening 11c at the center. A bearing 11d is provided at the end of the opening 11c.

  A rectangular plate-shaped stopper member 12 is disposed in the opening portion 11c, and the stopper member 12 is rotated upward from the horizontal position by fitting the rotation shaft 13 to the base portion of the bearing portion 11d and the stopper member 12. It is pivotally supported so that it can move and tilt. The stopper member 12 is formed from a steel plate or the like that is attracted to the magnet. The base plate 11a is formed with an attachment hole 11e for fixing on the floor.

  On the other hand, the cover 11b covering the base plate 11a has an opening and a mounting hole similar to those of the base plate, and is fitted on the base plate 11a. The stopper member 12 is rotatable upward from the opening of the cover 11b.

  1, 6, and 7 illustrate the state in which the stopper member 12 is tilted obliquely upward. However, the stopper member 12 is placed in the opening 11 c of the mounting plate 11 by its own weight in a free state. Stored. Therefore, the stopper 1 normally has a flat planar shape. Further, the stopper 1 is formed to be as thin as, for example, about 3 mm. When the stopper 1 is attached on the floor, the protrusion height on the floor is minimized so that it does not become an obstacle on the floor.

  On the other hand, as shown in FIGS. 1 to 4, the stopper receiver 2 is configured by mounting a magnet 24 in a case 21 so as to be swingable. The case 21 is formed of a synthetic resin or the like in a shape having an open bottom surface and a semi-cylindrical curved upper surface. As shown in the cross-sectional view of FIG. 4, a magnet storage chamber 22 is formed inside the case 21 with an opening at the bottom, and a magnet case 23 holding a magnet 24 in the magnet storage chamber 22 can swing. It is stored. In addition, in the case 21, in order to attach the stopper holder 2 to the lower part of the sliding door, an attachment hole 26 is formed in the horizontal direction, and an attachment hole 27 is also formed in the vertical direction perpendicular thereto.

  The magnet 24 is formed in a cylindrical shape by a strong permanent magnet such as neodymium and is housed in a magnet case 23 as shown in FIG. The magnet case 23 has a shaft support portion 23a formed on the upper portion thereof, and a swing shaft 25 is fitted into the shaft support portion 23a in the horizontal direction. Then, both ends of the swing shaft 25 are fitted and inserted into the wall portion of the magnet storage chamber 22 of the case 21 so that the magnet case 23 can swing within a range of about 2 ° to 5 °, for example.

  In addition, as shown in FIG. 4, the magnet case 23 in which the magnet 24 is housed tilts the bottom surface of the magnet 24 backward by an angle θ (for example, about 5 °) from the bottom surface of the case 21 when the magnet case 23 is suspended by its own weight. (Inclined upward toward the rear in the moving direction of the sliding door). The swing surface along the swing direction of the magnet 24 is mounted so as to be the same as the tilt surface along the rotation (tilt) direction of the stopper member 12.

  Then, when the sliding door is stopped, the magnet 24 can swing so that the inclination angle θ of the bottom surface further increases in the above-mentioned angle range (for example, a range of about 5 ° to 10 °) as shown in FIG. it can. Such a swing of the magnet case 23 changes the inclination angle of the attracting surface of the magnet 24, and the attracting surface of the magnet 24 attracts the stopper member 12 even when the gap between the bottom surface and the floor surface of the sliding door varies depending on the construction. It matches the surface.

  The stopper 1 configured in this manner is attached to the floor just below the outset sliding door 3 by means of a mounting screw. As shown in FIGS. 8 and 9, the outset sliding door 3 has a traveling roller 5 attached to the top thereof, and the traveling roller 5 is engaged with an upper rail 4 attached to an upper portion such as a wall portion. Installed as possible.

  The direction of the stopper member 12 is such that the direction in which the stopper member 12 is attracted by the magnet and tilted upward is directed rearward in the moving direction of the outset sliding door 3 as shown in FIGS. Are mounted to tilt in a vertical plane. Since the stopper 1 is formed in a plate shape including the stopper member 12 and has a thickness of, for example, about 3 mm, the stopper 1 can be attached without being an obstacle on the floor.

  On the other hand, as shown in FIGS. 8 and 9, the stopper receiver 2 is attached with an attachment screw or the like so as to be embedded in the bottom of the outset sliding door 3. At this time, the stopper holder 2 is attached so that the swinging direction of the magnet case 23 inside thereof, that is, the attracting surface of the magnet 24 faces the rear of the sliding door moving direction. As a result, the swing surface (vertical surface) of the magnet case 23 coincides with the inclined rotation surface (vertical surface) of the stopper member 12, and the attracting surface of the magnet 24 coincides with the attracting surface of the stopper member 12. The magnet case 23 and the stopper member 12 can be tilted.

  The outset sliding door 3 is attached to the upper rail 4 so as to be able to run, but the gap between the bottom of the sliding door 3 and the floor surface is narrow or wide depending on the installation situation of the upper rail 4 at the construction site. To change. However, the stopper for the outset sliding door can be tilted so that the stopper member 12 on the floor is inclined at an arbitrary upper angle, and the magnet case 23 in the stopper holder 2 is also tilted by the stopper member 12. Therefore, the gap between the bottom of the sliding door and the floor surface can be changed from a relatively narrow gap L1 to a wide gap L2 as shown in FIGS. The stopper member 12 is normally attracted to the attracting surface of the magnet 24.

  When the outset sliding door 3 runs on the upper rail 4 and the stopper holder 2 at the bottom of the sliding door 3 reaches the stopper 1 on the floor, and the sliding door 3 stops by hitting an upper rail stopper (not shown), The stopper member 12 of the stopper 1 is attracted by the magnet 24 of the stopper holder 2 provided at the bottom of the sliding door 3 and tilted upward and is attracted to the magnet 24. Thereby, while the bottom part of the outset sliding door 3 stops, it is hold | maintained on a floor, the rebound at the time of the stop of the outset sliding door 3 is prevented, and the swing of the lower part of the sliding door 3 is also prevented. Therefore, the outset sliding door 3 can be stopped stably and satisfactorily.

  Thus, according to the stopper for the outset sliding door of the present invention, the rebound when the outset sliding door is stopped is prevented, and the swinging of the lower portion of the sliding door is prevented, so that the outset sliding door can be stably stopped. it can. Also, since the magnet case and stopper member can be tilted so that the magnet attracting surface matches the attracting surface of the stopper member, the gap between the sliding door and the floor surface changes depending on the construction status of the outset sliding door However, when stopped, the magnet tilts following the stopper member in response to the change in the gap, and the stopper member can be satisfactorily attracted to hold the sliding door.
