Description

  The present invention relates to a lateral opening / closing shutter device that does not include a lower guide rail as a mechanical guide member on a floor surface side, and does not include an upper suspension rail as a mechanical guide member on a ceiling surface side. In the floor surface side of the lower part of the shutter device, a row of permanent magnets composed of a plurality of permanent magnet elements is arranged opposite to each other along the sliding locus line of the shutter device. The present invention relates to a lateral opening / closing shutter device in which rows of permanent magnets composed of elements are arranged so as to face each other and are not provided with traveling rollers in the upper and lower sides and does not use a mechanical sliding structure. In the present invention, the term “sliding” does not mean that the shutter device moves with the floor surface or rail mechanically contacting, but the shutter device moves relative to the floor surface. Means.

  Conventionally, a shutter that opens and closes in the horizontal direction, called a horizontal pulling shutter, is known and is shown in FIG. The horizontal opening / closing shutter 200 suspends a shutter body 210 between a suspension upper rail 220 provided on a ceiling CL and a lower rail 230 provided on a floor surface FL, and guides and slides along the lower rail 230. It is something to be made. The upper and lower rails 220 and 230 of the shutter main body 210 are composed of upper and lower rail frame bodies 221 and 231 fixed to a part of the building, and the rail 222 is provided on the hanging upper rail 220. It has been. A shutter main body 210 is suspended from the rail 222 via a travel roller 223. The lower rail frame 231 is a U-shaped frame rail that is provided on the floor and opens upward. The U-shaped lower rail frame 231 includes guide rollers 232 attached to the lower part of the shutter main body 210. Functions as a guide groove. Accordingly, when the shutter main body 210 is operated left and right by hand, the shutter main body 210 suspended from the traveling roller 223 is guided by the guide roller 232 and opened and closed left and right.

  Such a conventional lateral opening / closing shutter requires a lower rail on the floor surface that mechanically slides the shutter device. Therefore, when the shutter device is open, The rail frame body 231 is exposed to a U-shaped groove that is open to the floor surface, so there is a concern that rainwater may accumulate or that dead leaves and dust may enter and adhere to cause contamination and corrosion. . In addition, there is an accident where a woman's high-heeled heel falls and falls. Therefore, it is known that when the shutter is opened, an open / close plate provided with a hinge mechanism is provided in the U-shaped opening groove of the lower rail frame 231 to close it, thereby closing the problem.

  For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 6-323072), the safety of a moving object, a pedestrian, or the like that blocks the lower rail groove and moves back and forth when the lateral shutter is opened, and the rail groove are maintained. In addition, the present invention provides a lower rail groove cover for a laterally-drawing shutter, which can also be applied to a lower rail groove having a non-linear groove. This is because the cover body that loosely fits the lower part of the horizontal shutter consisting of a plurality of panels into the lower rail groove and seals the open surface of the lower rail groove, and the pivoting fulcrum on one side edge of the lower rail groove The cover body can be opened up and down and divided into the required number of cover pieces by cutting the cover body into an inclined shape, and the cover pieces can be undulated in conjunction with the opening and closing operations of the horizontal shutter. It is composed.

  Further, Patent Document 2 (Japanese Patent Laid-Open No. 8-303159) aims to allow the U rail of the lower rail of the horizontal pulling shutter to be freely opened and closed. Depending on the opening and closing, the U rail is turned up and down or back and forth to close or open the U groove. The lower guide rail for the horizontal shutter is composed of a rail base frame having a concave cross section laid and a movable U-shaped rail fitted to the concave portion of the rail base frame. The movable U-shaped rail is provided so as to be mounted upside down in a U shape or an inverted U shape according to the opening / closing travel of the shutter.

Are a predetermined distance from each other on the floor surface FL across the sliding locus line 150 of the lateral opening / closing shutter device 100. They are spaced apart. Accordingly, if the lateral opening / closing shutter device 100 is pushed along the sliding locus line 150, it can be opened and closed with extremely small force. On the other hand, even if the lateral opening / closing shutter device 100 is pushed in the direction orthogonal to the sliding locus line 150, a pair of permanent magnets on the floor side with respect to the permanent magnet rows 141, 141, 141. .., 161, 161, 161..., 161, 161, 161.

  FIG. 5 shows the arrangement configuration of the magnet rows provided on the floor surface along the U-shaped sliding locus line 150. In this arrangement, a pair of permanent magnet rows 151, 151, 151... And 161, 161, 161... Are arranged along a U-shaped sliding locus line 150. The arrangement of magnets in the part 152 or 153 is different. That is, in the curve portion 152, a pair of permanent magnet rows 151, 151, 151..., 161, 161, 161. The rows 151, 151, 151... And 161, 161, 161. As described above, the shutter main body 110 can be arranged on the ceiling side without forming a pair of permanent magnet rows 151, 151, 151..., 161, 161, 161. In order to slide along the suspended upper rail 120, the pair of permanent magnets 151, 151 are arranged from either side of the curved portion 153 where the shutter body 110 is not provided with permanent magnets. 151... And 161, 161, 161. In order to ensure this introduction, although not shown, the entrance / exit side of a pair of permanent magnet rows 151, 151, 151... And 161, 161, 161. May be arranged in a trumpet shape.

  FIG. 6A shows a magnet unit 155 in which a plurality of permanent magnet elements 151 are arranged in close contact with each other. The magnet unit 155 is, for example, a rectangular parallelepiped cylindrical container 156 made of a material that is not attracted by a magnet such as aluminum or synthetic resin, and a plurality of permanent magnet elements 151, 151, 151,.・ Insert. At both ends of the cylindrical container 156, the magnet element 151 is prevented from popping out by lids 157 and 157 that are appropriately secured with screws or the like. In the present invention, the magnet units 155, 155, and 155 are attached to the structure below the floor surface FL with appropriate fixing bands 159, 159, 159, etc., and arranged in a pair of rows ( FIG. 6 (B)). In FIG. 6B, the floor surface FL is disposed on the structure, but is not shown.

  Hereinafter, in the description of FIGS. 7A and 7B, the directional relationship is described according to the direction on the drawing. 7A and 7B show details of the arrangement relationship of the upper and lower permanent magnet elements 141, 151, 161 as a part of the permanent magnet elements in the row of the permanent magnets. In the figure, two rows of permanent magnets are arranged on the floor, and one row of permanent magnets is arranged on the shutter main body 110 that slides along the sliding locus line.

  7A, the magnetic lines of force of the permanent magnet elements 141 (or permanent magnet rows 141, 141, 141...) On the shutter body 110 side are two rows of permanent magnets on the floor surface side. 151, 151, 151... And 161, 161, 161... Slightly overlap in the vertical direction. By arranging the magnetic poles in such a relationship, the permanent magnet elements 141 on the shutter body 110 side (or the permanent magnet rows 141, 141, 141...) Are arranged on the floor surface side in two rows of permanent magnets 151. , 151, 151..., 161, 161, 161... Receive the same strong forces F, F and are prevented from swinging left and right in the direction shown. However, the permanent magnet element 141 (or the permanent magnet rows 141, 141, 141...) On the shutter main body 110 side in the illustrated direction is not prevented from sliding in the vertical direction of the drawing. Thus, if the shutter main body 110 is operated by hand in the illustrated vertical direction, the shutter main body 110 suspended from the traveling roller 123 has the permanent magnet rows 151, 151, 151... And rows 161, 161 on the floor surface. , 161... And is opened and closed in the illustrated vertical direction. The distance between the rows 151, 151, 151 ... of the permanent magnets arranged on the floor surface and the rows 161, 161, 161 ... can be changed by the thickness of the shutter main body 110, but generally 30 It is arranged at a predetermined distance of about ˜50 mm.

  In FIG. 7B, one row of permanent magnets 151, 151, 151... Is arranged on the floor surface, and the shutter main body 110 that slides along the sliding locus line has two rows of permanent magnets. The rows 141a, 141a, 141a,... And 141b, 141b, 141b,. In FIG. 7B, the lines of permanent magnets 141a, 141a, 141a ... and 141b, 141b, 141b ... on the shutter body 110 side are lined with permanent magnets 151 on the floor surface side. , 151, 151... Slightly overlap in the vertical direction. By arranging the magnetic poles in such a relationship, two rows of permanent magnets 141a, 141a, 141a ... and 141b, 141b, 141b ... on the shutter body 110 side are arranged in one row on the floor surface side. From the permanent magnet rows 151, 151, 151,..., Strong forces F, F having the same magnitude are received, and swinging to the left and right in the illustrated direction is prevented. However, the permanent magnet rows 141a, 141a, 141a... And 141b, 141b, 141b... On the shutter main body 110 side in the illustrated direction are not prevented from sliding in the vertical direction of the drawing. Thus, if the shutter body 110 is manually operated in the illustrated vertical direction, the shutter body 110 suspended from the traveling roller 123 is guided along the permanent magnet rows 151, 151, 151. Are opened and closed in the illustrated vertical direction. Such a configuration is appropriate when the shutter main body 110 is thick, and can be configured to be self-supporting and have a low risk of falling if the shutter main body 110 has a sufficient thickness. A configuration in which the upper rail 120 for hanging the ceiling surface is not provided is also possible.

  From this, the arrangement of the opposed permanent magnet rows can be easily arranged in 2 rows for 1 row, 3 rows for 2 rows, 4 rows for 3 rows, etc. I can think of it. In other words, when one permanent magnet row is n, it is desirable to arrange (n + 1) other permanent magnet rows facing each other.

  In the present embodiment, the permanent magnet element 141 provided at the lower end of each strip-shaped shutter unit 101 has an S pole arranged upward and an N pole arranged downward. In the illustrated embodiment, a block-shaped magnet element is used, but instead of this, a plurality of plate-shaped permanent magnets may be bonded together with an adhesive. The permanent magnet element 141 is preferably provided close to the floor surface at a distance of about 2 to 4 mm from the lowest end of each strip shutter unit 101.

  On the other hand, the permanent magnet rows 151, 151, 151..., 161, 161, 161... Are buried about 5 to 10 mm below the floor, and the sliding locus line 150 of the lateral opening / closing shutter device 100 (FIG. 2). They are provided in parallel at a predetermined distance along (B) and FIG. The permanent magnet rows 151, 151, 151..., 161, 161, 161... Embedded in the embodiment shown in FIG. Permanent magnet units composed of a plurality of permanent magnet elements are arranged in a row, but instead of block-like permanent magnet elements, two or more thin magnets are bonded together with an adhesive. It does not matter as a unit configuration. However, it is necessary to arrange the plurality of magnet elements in close contact with each other, and the polarity opposite to the vertical polarity of the permanent magnet 141 provided at the lower end of each strip-shaped shutter unit 101, that is, illustrated in the drawing. In the embodiment, it is necessary to dispose the N pole facing upward and the S pole facing downward.
