Description

  The present invention relates to an opening / closing member useful for partitioning a space such as a conference room and the like, and a partition unit using the same.

  Partition curtains are widely used to partition various spaces such as conference rooms, banquet halls, and reception rooms. As an opening / closing member for opening / closing such a partition curtain, a magnet disposed on the opposing surfaces of a pair of long opening / closing members is usually used. However, if a magnet is disposed on the opposing surface of the opening / closing member, an attracting sound is generated in which the magnet is magnetically attracted when closed. Therefore, a mounting recess is usually formed along the longitudinal direction on the opposing surfaces of the pair of opening / closing members, and a plurality of magnets and a cushion having elasticity are provided between the magnets in the mounting recess. The materials are arranged alternately. And in order to reduce an adsorption | suction sound, the said cushion material is curving or protruding to the opposing surface side rather than the magnet. As the cushion material, a sheet-like molded body that can be mounted in the mounting recess and is curved or bent on the opposite surface side is generally used. However, such an opening / closing member requires positioning and fixing of a plurality of magnets and a cushioning material mounting operation, and the assembly operation is complicated. Further, since the cushion material is curved or bent to the opposite surface side, the tip of the cushion material first comes into contact with the closing operation, so that the attractive force of the opening / closing member by the magnet is reduced and the magnetic force of the magnet is reduced by the opening / closing member. Cannot be used effectively for opening and closing.

  Japanese Patent Application Laid-Open No. 2000-220355 (Patent Document 1) supports a large number of panels so as to be movable along a hanger rail, and each panel is rotatably connected to each other so that the end of the panel positioned at the head In the partition panel in which the head rod is suspended from the hanger rail via the leading runner, the leading rod is provided with suction means for closely attaching the leading rod to the wall surface. A partition panel is disclosed in which a cover is attached to the tip of the ridge so as to cover the suction means, and the cover can be removed so as to expose the suction means. In this document, the attracting means is constructed by attaching a magnet receiver attached to the wall surface when the magnet is attached to the leading edge and the cover is removed to expose the magnet. It is described to do. This document describes that the cover is a cushion rubber.

  This attracting means is composed of a cushion rubber and a magnet, and the protrusion of the yoke plate formed on the magnet is attracted to a magnet receiver composed of a metal plate. And at the time of closing, the front-end | tip part of cushion rubber bends and it adheres to a wall surface. Therefore, the attracting means has a low magnetic attractability, and it is difficult to suppress a closing sound due to closing. Further, when the panel using the hanger rail as a fulcrum swings, the position of the protrusion of the yoke plate with respect to the magnet receiver shifts. Therefore, in order to accurately position the protrusions of the yoke plate on the magnet receiver, it is necessary to move the panel along the hanger rail without swinging, and the opening / closing operation is complicated and the panel is carefully closed. Need to be moved to. Furthermore, the cover excision and the construction of the suction means are complicated, and the assembling workability of the partition panel is also lowered.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an opening / closing member having a high magnetic attractive property and reduced closing sound due to closing, and a partition unit using the same.

  Another object of the present invention is to provide an opening / closing member that does not cause a displacement due to a closing operation and a partition unit using the same.

  Still another object of the present invention is to provide an opening / closing member that can be easily constructed by a simple assembling operation, and a partition unit using the same.

  As a result of earnest studies to achieve the above-mentioned problems, the present inventor constituted at least one of the pair of magnetic adsorption members as a soft magnet member containing magnetic powder and a soft resin. It has been found that the magnetic attraction can be improved without using the conventional cushioning material, and that the closing sound due to closing can be effectively reduced, and the present invention has been completed. Furthermore, the present inventor makes adjacent magnetic poles (N pole and S pole) adjacent to each other in the width direction of the facing portions of the pair of opening and closing members, and on the opposing surfaces of the pair of opening and closing members, On the other hand, when the magnet member is made to face with the S pole facing the S pole and the N pole with respect to the S pole, the magnetic poles that repel each other and are attracted with different polarities can be used without causing misalignment. It has been found that the pair of members can be closed smoothly.

  That is, the opening / closing member of the present invention includes a pair of opening / closing members provided with a pair of members that can be opposed to each other and a magnetic attracting member that is disposed on the opposing surfaces of the pair of members and that can be magnetically attracted to each other. It is. In the opening / closing member, a first magnet member is disposed with different magnetic poles adjacent to each other in the width direction of one member of the pair of members, and a ferromagnetic member or the first member is disposed on the opposite surface of the other member. A second magnet member is disposed with a magnetic pole opposite to the magnetic pole of the magnet member, and at least the first magnet member of the first and second magnet members is made of a magnetic powder and a soft material. It is comprised with the soft magnet member containing resin.

  The opening / closing member has a first soft magnet member disposed adjacent to different magnetic poles in the width direction of one of the pair of members, and the first soft magnet member is disposed on the opposite surface of the other member. The second soft magnet member may be disposed with the opposite magnetic pole directed to the surface. In such an opening / closing member, even when the axis of at least one member deviates from the axis of the other member due to swinging or the like during the closing operation, the magnet member is disposed with the opposite magnetic pole facing the opposite portion. Therefore, the position shift can be corrected by the magnetic attractive force. The opening / closing member is composed of a long member in which at least one member is slidable and a pair of members can be opposed to each other, and the first and second magnet members are composed of soft magnet members. Each member may be mounted on a mounting portion formed in the longitudinal direction on the opposing surfaces of the pair of members. One member may be slidable with respect to the other member fixed to the fixing portion. The opening / closing member may include a groove-shaped mounting portion extending in the longitudinal direction on the opposing surfaces of the pair of members, and a soft magnet member slidably mounted on the groove-shaped mounting portion. When the opening / closing member is provided and the groove-shaped mounting portion is provided, the opening / closing member can be easily constructed by a simple assembling operation of inserting the magnet member into the groove-shaped mounting portion.

A mounting recess formed in a longitudinal direction on a surface facing the one member and a mounting pole in the longitudinal direction of the mounting recess, and a magnetic pole opposite to the magnetic pole of the first soft magnet member And a second soft magnet member facing each other.

  The opening / closing member may include an operation portion for opening / closing operation on a side portion of at least one member of the pair of members. The operation part includes an extension part extending from a side part of one member and a grip part formed at an end part of the extension part, and the grip part corresponds to the extension part. And may be positioned in the opening direction of the opening and closing direction. With such a gripping portion, in the opening operation of the opening / closing member, a traction force (or pulling force) acts on the opening / closing member from an oblique direction with respect to the facing direction of the magnet member. Although the attractive force of the pair of magnetic attracting members is strong in the opposing direction, it is weak to the pulling force from the oblique direction, and once the sides of the attracting surfaces of the pair of magnet members are opened, the magnetic force The magnetic attracting force of the attracting member is suddenly weakened. Therefore, when such an operation part is provided, the opening and closing member can be easily opened and closed.

  The opening / closing member may include an attachment portion for attaching the partition sheet to at least one member of the pair of members. The attachment portion may be formed on a side portion opposite to the facing surfaces of the pair of members. The opening / closing member may include a positioning portion that can be positioned with respect to the attachment portion of at least one member, and may further include a pressing member for sandwiching the partition sheet at a portion other than the positioning portion. When such a pressing member is provided, the pressing member can be positioned with respect to one member, so that the opening / closing member can be easily assembled while preventing the partition sheet from being displaced. The opening / closing member may constitute a partition member for partitioning the space along the rail.

The partition unit is a partition unit including a pair of support members for sandwiching and supporting the partition sheet in the middle of the partition sheet, and the sandwiching surface capable of sandwiching the partition sheet among the pair of support members. However, you may have an uneven | corrugated surface symmetrical in cross-sectional shape. When such an uneven surface is provided, the opening / closing member can be easily assembled without mistaking the mating member.

  In the present specification, the “pair of members” or the “member” may be referred to as “a pair of opening / closing members”, “opening / closing members”, or “bar-shaped members”. Further, the “soft magnet member” may be referred to as “magnet cushion member”, “rubber magnet member”, or “rubber magnet member (rubber magnet member)”. “Magnet member” is used to mean both “soft magnet member” and “member made of magnets”.

  In the present invention, since at least one of the pair of magnetic attracting members is composed of a soft magnet member including magnetic powder and soft resin, the magnetic attractability can be improved and the closure can be improved. The closing sound can be reduced. Further, different magnetic poles (N pole and S pole) are adjacent to each other in the width direction of the facing portion of the pair of opening / closing members, and on the facing surfaces of the pair of opening / closing members, the opposite magnetic poles (S pole for N pole, When the magnet member is made to face with the N pole facing the S pole, the pair of rod-like members can be smoothly closed without causing a positional shift. Furthermore, since the magnet member having the opposite magnetic pole may be opposed at the opposed portion, the assembling operation of the opening / closing member is simple. In particular, when the opening / closing member is configured by the dovetail-shaped mounting portion and the magnet member slidably mounted on the dovetail-shaped mounting portion, it can be easily constructed by a simple assembly operation.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings as necessary. 1 is a schematic exploded perspective view showing one rod-like member of the opening / closing member of the present invention, FIG. 2 is a schematic sectional perspective view showing the opening / closing member of FIG. 1, and FIG. 3 is an opening / closing member of FIG. It is a schematic sectional drawing which shows.

  In the example shown in FIG. 1, the opening / closing member constitutes an opening / closing member of a curtain-type partition unit for partitioning a space such as a conference room. The opening / closing member includes a pair of long hollow cylindrical rod-shaped members 1a and 1b having a rectangular cross section, and dove-shaped mounting recesses 3a and 3b formed on the opposing surfaces of the rod-shaped members along the longitudinal direction; The first and second soft magnet members 2a and 2b in the form of elongated or strips mounted along the longitudinal direction in the mounting recesses 3a and 3b, and one of the pair of rod-shaped members 1a and 1b. It is attached to the side part of the member 1a, and is formed to extend from an operation part 5a for opening and closing the opening and closing member, and a side part opposite to the facing surface of the pair of rod-like members 1a and 1b, And the attachment parts 9a and 9b for attaching the partition sheets 8a and 8b are provided. The rod-like members 1a and 1b are formed by extrusion molding of aluminum.

  The cross-section of the mounting recesses 3a, 3b has a groove-like shape with the opening side narrowed, improving the mounting properties of the soft magnet members 2a, 2b and preventing the falling off. That is, the mounting recesses 3a and 3b have a substantially U-shaped cross section, a substantially U-shaped recess having a wide back portion, and a step-like extension from the recess at the back to the side, and a wide opening. The part side is comprised by the step-shaped recessed part formed with the substantially U-shaped recessed part narrowed rather than the recessed part of the said back part.

  In order to prevent the soft magnet members 2a and 2b from falling off and being detached from the mounting portion recesses 3a and 3b, the end portions (lower end portions) of the mounting recesses 3a and 3b of the rod-shaped members 1a and 1b are L-shaped. The stopper 4 a is arranged and fixed with screws 21.

  The soft magnet members 2a and 2b have a cross-sectional shape corresponding to the mounting recesses 3a and 3b, and in the mounted state, the opposing portions of the soft magnet members 2a and 2b protrude from the mounting recesses 3a and 3b. That is, both side portions of the soft magnet members 2a and 2b are formed in a step shape thinner than the central portion in the width direction, and can be slidably disposed in the recesses on the opening side of the mounting recesses 3a and 3b. In the mounting state in the mounting recesses 3a and 3b, the opposing surfaces of the soft magnet members 2a and 2b are thicker than the depth of the recesses on the opening side of the mounting recesses 3a and 3b, and protrude from the mounting recesses 3a and 3b so as to face each other. Yes. Therefore, the pair of rod-like members 1a and 1b can enhance the magnetic attractiveness by utilizing the magnetic action of the soft magnet members 2a and 2b, and the soft magnet members 2a and 2b projecting from the mounting recesses 3a and 3b. The closing sound due to closing of the opening / closing member can be reduced or buffered.

  As shown in FIG. 2, the first soft magnet member 2a mounted in the mounting recess 3a of one bar-shaped member (or first bar-shaped member) 1a is adjacent to the width direction and extends in the longitudinal direction. And S poles. The second soft magnet member 2b mounted in the mounting recess 3b of the other rod-shaped member (or second rod-shaped member) 1b makes the opposite magnetic pole face the magnetic pole of the first soft magnet member 2a. ing. That is, the south pole of the second soft magnet member 2b is directed to the north pole of the first soft magnet member 2a, and the second soft magnet member is directed to the south pole of the first soft magnet member 2a. The first and second soft magnet members 2a and 2b are mounted in the mounting recesses 3a and 3b, respectively, with the N pole of 2b facing. Therefore, in the closing operation of the opening / closing member, the second rod-shaped member 1b is displaced with respect to the first rod-shaped member 1a (for example, the axis of the second rod-shaped member 1b is relative to the axis of the first rod-shaped member 1a). Even if the position is shifted, the magnetic action of the N pole and the S pole can be used to close the position at an accurate position without shifting. Although it is difficult to visually distinguish the magnetic poles (N pole and S pole), the N pole and the S pole are illustrated in the soft magnet members 2a and 2b in order to help understanding.

  One of the pair of rod-shaped members 1a, 1b has an operation portion 5a for opening / closing operation on one side. The operating portion 5a includes two extending portions 6a extending in the side direction from the side wall of one rod-shaped member 1a, a connecting portion extending from the extending portion 6a in the opening direction of the opening / closing operation, And a gripping portion 7a for connecting the end portions of the connecting portion. That is, the planar shape of the operation portion 5a is formed in an L shape. Therefore, the gripping part 7a is located at the position in the opening direction of the opening / closing direction with respect to the extending part 6a. A concave groove (or a groove-shaped concave portion) extending in the longitudinal direction is formed on both sides of the pair of rod-like members 1a, 1b, and the base portion 8a of the operation portion 5a slides along the concave groove. Is possible. Therefore, the base portion 8 a of the operation portion 5 a can be positioned in the height direction and attached to the side walls of the members 1 a and 1 b with the screws 22. A base portion of the operation portion 5a is screwed with a screw 22 and attached to one side portion of the rod-shaped member 1a. If such an operation part 5a is formed, even if the soft magnet members 2a and 2b are magnetically strongly attracted, the opening / closing member can be easily opened with a small force.

  As shown in FIG. 3, the gripping portion 7a attached to the side wall of one of the rod-shaped members 1a is located downstream in the opening direction with respect to the extending portion 6a. When pulling in the opening direction of the opening / closing operation, a torsional force acts on the operating portion 5a and one of the rod-shaped members 1a, and among the adsorbing portions of the soft magnet members 2a and 2b, the end opposite to the operating portion 5a is moved. As the fulcrum 18, the attracted soft magnet members 2a and 2b are detached. That is, although the magnetic attractive force of the pair of soft magnet members 2a and 2b is strong in the opposing direction, it is weak against the pulling force (or pulling force) from the oblique direction, and the pair of soft magnet members 2a, 2b, Once the side of the attracting surface 2b is opened, the magnetic attracting force of the soft magnet members 2a and 2b is suddenly weakened. Therefore, the magnetic attractive force by the soft magnet members 2a and 2b can be easily released.

  Further, attachment portions 10a and 10b for attaching the partition sheets 9a and 9b extend to the side portions (side walls in the opening direction of the opening / closing operation) opposite to the opposing surfaces of the pair of rod-like members 1a and 1b. Is formed. That is, the attachment portions 10a and 10b are provided with attachment walls for attaching the partition sheets 9a and 9b, extending in the opening / closing direction, and are formed in a hollow quadrangular cross-section with chamfered or cut off end corner portions. Has been. The partition sheets 9a and 9b are sandwiched between the mounting walls of the mounting portions 10a and 10b and the pressing members 11a and 11b, and the mounting wall and the pressing members 11a and 11b are screwed together with screws 23, thereby a pair of rod-shaped members 1a and 1b. The partition sheets 9a and 9b can be attached to each other, and a partition unit is formed by attaching the partition sheets 9a and 9b to the opening / closing member. The cross-sectional shape of the pressing members 11a and 11b is a U-shape in which both side end portions are bent in an L shape, and the partition sheets 9a and 9b are sandwiched with the front ends of the bent portions facing the partition sheets 9a and 9b. In addition, the partition sheets 9a and 9b are firmly held by screwing.

  Furthermore, the bottoms of the pair of rod-like members 1a and 1b are covered with a cap 12a. The cap 12a has a shape corresponding to the cross-sectional shape of the bottom of the pair of rod-shaped members 1a and 1b, and is a convex insertion that can be inserted into a groove extending in the longitudinal direction of the side portion of the pair of rod-shaped members 1a and 1b. A portion 13a is provided.

  Furthermore, runners 14a are attached to the top portions (upper portions) of the pair of rod-like members 1a and 1b in order to suspend the opening / closing member and move it along the rail. The runner 14a is formed in a U-shape that can be inserted into the hollow portions of the rod-shaped members 1a and 1b, and a hanging portion 15a that can be attached to the upper ends of the rod-shaped members 1a and 1b by screws 24 and nuts 25; A roller portion 16a for rotating and moving along the rail, a ring portion 17a that is swingably attached to the roller portion 16a, and a screw portion for attaching the ring portion to the suspension portion 15a 26.

  In such an opening / closing member and the partition unit, the opening / closing member (the pair of rod-shaped members 1a, 1b) is moved along the rail, and the magnetic attractive force of the pair of soft magnet members 1a, 1b is used to make a pair of rod-shaped members. Without reducing the position of the members 1a and 1b, it is possible to smoothly partition the predetermined space with the partition sheets 8a and 8b while reducing the closing sound at the time of closing. Moreover, the predetermined space can be easily opened by releasing the magnetic attractive force of the pair of soft magnet members 1a and 1b using the operation unit 5a.

  FIG. 4 is a schematic sectional view showing another example of the opening / closing member of the present invention. FIG. 5 is a schematic cross-sectional perspective view showing the opening / closing member of FIG. 4. FIG. 6 is a schematic cross-sectional view showing a pair of support members for supporting the partition sheet in the middle of the partition sheet.

  4 and 5, the other rod-like member 31 is screwed and fixed to the wall surface 34 with a screw 35, and one rod-like member 41 is slidable with respect to this member 31, and the other rod-like member. One bar-like member 41 can be opened and closed with respect to 31. That is, the other rod-shaped member 31 is formed in a plate shape, and has a dovetail-shaped mounting recess 32 formed along the longitudinal direction on the surface facing the one rod-shaped member 41, and the second soft magnet member 2b. A similar second soft magnet member 33 is provided. A shallow concave groove 36 is formed along the longitudinal direction of the rod-shaped member 31 on the back surface opposite to the opposed surface of the rod-shaped member 31 in order to facilitate along the wall surface 34 and increase the tightening force by the screw 35. Has been.

  As with the mounting recess 3a and the first soft magnet member 2a, one rod-shaped member 41 has the first soft magnet member 43 mounted in the mounting recess 42, and the partition sheet 48 is attached to the one rod-shaped member 41. A pressing member 44 is provided for clamping between the two. That is, one rod-like member 41 has a hollow cross-sectional shape, and from one side (the right side in FIG. 5) of the wall surface of the mounting recess 42 to the rear (opposite direction with respect to the facing surface, or The inner side wall is formed as a pressed wall 45 extending in the opening / closing direction). In the pressed wall 45, the bar-like member 41 protrudes laterally (leftward in FIG. 5) away from the wall surface of the mounting recess 42 and extends in the longitudinal direction, and is formed as a protrusion 46 (or ridge). And the clamping part 51 which can clamp the partition sheet | seat 48 is provided in the back side part from the wall surface of the mounting recessed part 42. As shown in FIG. The pressing member 44 has a hollow cross section, and is formed so as to be fitted to and mounted on the opposing wall 50 with respect to the pressed wall 45 and the protruding portion 46 on the opposing wall 50 and extend in the longitudinal direction. A concave portion 47 (or a concave groove) having a U-shaped cross section, and a pressing portion 52 capable of clamping the partition sheet 48 between the pressing portion 51 and a side portion on the rear side from the wall surface of the mounting concave portion 42. Is formed.

  In the opening / closing member having such a structure, by using the protrusion 46 of the rod-shaped member 41 and the recess 47 of the pressing member 44, the pressing member 44 is moved relative to the rod-shaped member 41 while preventing the position shift of the partition sheet 48. Therefore, the opening / closing member can be easily assembled by fixing with the screw 49 in the fitted state. Moreover, the holding | maintenance property of a partition sheet can be improved using the clamping parts 51 and 52. FIG.

  As shown in FIG. 6, the middle portion of the partition sheet 62 may be supported by being sandwiched between a pair of support members 61a and 61b. The sandwiching surfaces of the pair of support members 61a and 61b have curved concavo-convex portions 63 and 64 having symmetrical cross-sectional shapes. That is, a screwing portion 66 for screwing with a screw 65 is formed at the center of the opposing surfaces of the pair of support members 61a and 61b, and the clamping surface is formed symmetrically from the screwing portion. Has been. When sandwiched between the concavo-convex portions 63 and 64, the partition sheet 62 can be prevented from being displaced, and the partition sheet 62 can be firmly held. Furthermore, since the concavo-convex portions 63 and 64 are symmetrical, the opening / closing member can be assembled easily and reliably without causing the pair of support members 61a and 61b to face each other by mistake. Moreover, since the cross-sectional shape is curved, even if the partition sheet is sandwiched, wrinkles are hardly generated and can be prevented from being damaged.

  The pair of opening / closing members can be constituted by a pair of members that can be opposed to each other, and the length of the opening / closing member is not particularly limited, and may be short or long depending on the application. When a space such as a conference room or a banquet room is partitioned, a long member is usually used in many cases. At least one member (one or both members) may be a movable (or slidable) member. In addition, the other member may be a member fixed to a fixed part such as a wall or a pillar in addition to a movable (or slidable) member. The shape of the member may be a rod shape, a columnar shape, a plate shape, or the like. Further, the cross-sectional shape of the member may be a circular shape, an elliptical shape, a polygonal shape [triangular shape, quadrangular shape (square shape, rectangular shape, etc.), pentagonal shape, etc.]. In addition, the member (particularly the movable member) may be solid, but it is advantageous to be hollow in order to reduce the weight. In addition, although the said member may have a hollow part in part, the whole is hollow in many cases. The pair of members may be formed of different materials, or may be formed of the same material. The pair of opening / closing members may be formed of wood, plastic, or the like, and partition members such as a partition curtain may be formed of metal such as aluminum from the viewpoint of strength.

  At least one of the members that can face each other may be slidable, or both members may be slidable. The member slide mechanism includes the rail (guide means such as a hanger rail) and a slide member that can move on the rail (runner member that can roll on the rail and is supported by being suspended from the rail) ) And an attachment member for attaching the slide member to the member. As described above, a swing member such as a ring may be interposed between the slide member and the attachment member. Moreover, the lower part of the member may be slidably supported by the rail. For example, you may attach the runner or roller member which can slide or roll along a rail to the lower part (or lower end surface) of a member.

  The opening / closing member may have a mounting portion for mounting the magnetic attracting member, and this mounting portion can be formed at an appropriate position of the member, but is usually formed at a facing portion of the member. Many.

  The mounting portion is not particularly limited as long as the magnetic attraction member can be mounted. The mounting portion may be formed by a convex portion, a protrusion, or the like, but is often formed by a concave portion. Further, the mounting portion may be a flat surface to which the magnetic attracting member can be attached. Further, the mounting portion may be formed over the entire length along the longitudinal direction (or axial direction) of the pair of rod-shaped members, or may be formed extending in the longitudinal direction leaving both end portions, or partially ( For example, it may be formed discretely along the longitudinal direction). For example, you may form at regular or irregular intervals along the longitudinal direction (or axial direction) of a rod-shaped member. The mounting portion is advantageously a mounting recess extending in the longitudinal direction of the rod-shaped member in order to improve the mounting property of the long or narrow magnetic attraction member. The cross-sectional shape of the mounting part is not particularly limited as long as it can be fixed with a magnetic attracting member, and is a U-shaped cross section, a trapezoidal shape with the opening side widened, a polygonal shape with a narrowed opening side (triangular shape, etc.), etc. It may be a hollow shape in which a magnetic attracting member can be mounted or inserted if necessary. A preferred mounting part is a form in which the magnetic attraction member can be easily mounted by a slide, for example, a groove shape with a narrowed opening side (for example, a cross-sectional circle shape, a cross-sectional elliptical shape, a cross-sectional trapezoidal shape, a cross-section with a narrowed opening side A U-shape, a step-shaped recess whose width is narrower than the recess at the back and the opening side is narrower than the recess at the back, and the like. In particular, it is preferable that the magnet member (particularly the soft magnet member) can be mounted by sliding in a mounting recess extending in the longitudinal direction of the rod-shaped member. Note that the magnetic attraction member may be attached to the attachment portion by a fixing means such as an adhesive or a screw.

  Although not necessarily required as long as the magnetic attracting member is held by the mounting portion, the mounting portion or the opening / closing member has a stopper, a fixing member, or the like falling off to prevent the magnetic attracting member from dropping from the mounting portion. Prevention means may be attached. The drop-off preventing means can be arranged at an appropriate position according to the type and number of magnetic attracting members.

  The opening / closing member does not necessarily include an operation unit (or handle), but preferably includes an operation unit for opening / closing the opening / closing member and the partition unit. This operation part can be formed in at least one (one or both) bar-shaped member among the opening and closing members. The operation unit may be attached to both side walls (or both side surfaces) of the opening / closing member, or may be attached to one side wall (or side surface). In the pair of opening / closing members facing each other, the operation section may be attached to one side wall of one member and the other side wall of the other member. Furthermore, you may attach an operation part to one side wall (or side surface) which adjoins among a pair of opposing opening-and-closing members. In addition, the said operation part can be formed in the suitable place of an opening-and-closing member. Moreover, when attaching the said operation part to the both sides wall of an opening-and-closing member, the attachment position (height) may be the same and may differ.

  The form of the operation part is not particularly limited, and may be a concave part, a convex part, a rod-like body or the like that can be locked by a finger, or a handle-like grip part formed on the side surface of the opening / closing member. Further, the planar shape of the operation portion may be a frame shape extending laterally from the side surface of the opening / closing member, a frame shape bent or curved in the closing direction in the opening / closing operation, and opening in the opening / closing operation. A frame shape bent or curved in the direction may be used, and the shape of the frame-shaped operation unit may be a frame shape such as a U-shape or an arch shape on the side surface. A base portion of the operation portion may be slidably inserted along both mounting portions (such as a concave groove or a groove-shaped concave portion) formed to extend in the longitudinal direction on both side portions of the pair of members. In the form in which the operation unit is slidable or slidable with respect to the mounting unit, the base of the operation unit is inserted by sliding along the mounting unit, positioned in the height direction, and fixed by fixing means such as a screw. Thereby, the said operation part can be attached to the side wall of a rod-shaped member by simple operation.

  The operation part usually includes an extension part extending from a side part of the opening / closing member and a grip part formed at an end part of the extension part. The extending portion may extend laterally from a side portion of the member, and extends in an oblique direction with respect to the lateral side (for example, obliquely with respect to an opening direction (reverse movement direction) of the opening / closing operation). It may be. A preferable operation part includes an extension part extending from a side part of one member and a grip part formed at an end part of the extension part. In the opening / closing direction. That is, the grip portion is curved or bent in the opening direction of the opening / closing direction with respect to the extending portion.

  The pair of members includes a magnetic attracting member on each facing surface (or facing portion). At least one of the pair of magnetic attracting members can be a soft magnet member. The other magnetic attracting member can be composed of a soft magnet member, a member composed of magnets, a ferromagnetic member (a member composed of iron, nickel, cobalt, an alloy thereof, or the like).

  In both of the single-opening method (a method that opens in one direction) and the double-opening method (a method that can be opened and closed in both the left and right directions), at least one of the pair of magnetic attracting members is at least one magnetic attracting member. It may be a soft magnet member, and the other magnetic attracting member may be at least one selected from a soft magnet member, a member composed of magnets, and a ferromagnetic member.

  Further, in general, in a single-opening type member, any of a soft magnet member, a member made of magnets, and a ferromagnetic member may be fixed to a fixing member such as a wall or a column. In the double-opening type member, a magnet member (particularly, a soft magnet member) may be disposed on both rod-like members.

  As a preferable combination of magnetic attracting members, a combination in which at least one magnetic attracting member is a soft magnet member and the other magnetic attracting member is a soft magnet member or a member composed of magnets, can be mentioned. In particular, a combination in which both magnetic attracting members are soft magnet members is preferable.

  The first magnet member disposed on one member is composed of a soft magnet member (magnet cushion member, rubber magnet member, or rubber magnet member (rubber magnet member)) containing magnetic powder and soft resin. Yes.

  Examples of the magnetic powder include transition metal elements and alloys thereof, high permeability ferrite (such as iron-nickel alloy) mainly composed of iron oxide, permanent magnets, powder magnets, and rare earth magnets. These magnetic powders may be used alone or in combination of two or more. Examples of the soft resin include thermoplastic resins [olefin resin, polyester resin, polyamide resin, urethane resin, synthetic rubber (diene rubber, olefin rubber, acrylic rubber, fluorine rubber, urethane rubber, etc.). And thermoplastic elastomer]. These soft resins may be used alone or in combination of two or more.

  In a conventional opening / closing member composed of a magnet member and a cushion member, the cushion member protrudes more forward than the magnet member, so that the magnet member has low adsorptivity and further suppresses closing sound caused by closing. It is also difficult. However, when a soft magnet member is used for at least one of the pair of magnetic attracting members, the magnetic attractability can be improved and the closing sound due to closing can be reduced. Furthermore, such a soft magnet member is easy to process and can improve the mounting property to the mounting portion.

  The soft magnet member is commercially available and can be easily obtained. If at least one of the magnetic attracting members is composed of the soft magnet member, a narrow magnet member can be easily formed, and can be easily mounted along the longitudinal direction of the mounting portion, thereby greatly increasing the assembly workability of the opening / closing member. Can improve.

  The magnetic characteristics such as the residual magnetic flux density and the maximum energy product of the magnetic attracting member can be appropriately selected depending on the application. The residual magnetic flux density can be selected from, for example, about 1 to 20 kG (preferably 2 to 15 kG, more preferably 3 to 10 kG). The maximum energy product can be selected from, for example, about 0.3 to 40 MGOe (preferably 0.4 to 30 MGOe, preferably 0.5 to 20 MGOe).

  The magnetic attraction member may be disposed on the opposing surfaces (or opposing portions) of a pair of members that can oppose each other. In many cases, the magnetic attracting member can be mounted on the mounting portion, and is button-shaped (circular, elliptical, etc.), polygonal (triangular, quadrangular, pentagonal, etc.), elongated or narrow The shape (or long shape or strip shape) may be used.

  The magnetic attraction member may be arranged over the entire length along the longitudinal direction of the opening / closing member, and may be arranged partially (or discretely) and regularly or irregularly in the longitudinal direction of the opening / closing member. You may set up. In the pair of magnetic attracting members, it is sufficient that at least a part of the other magnetic attracting member is opposed to the one magnetic attracting member.

  In many cases, the magnetic attraction member is mounted on a mounting portion (such as the dovetail mounting portion) formed in the longitudinal direction at a portion opposite to the pair of rod-shaped members. Furthermore, the magnet member may be attached to the attachment part in the form of fitting, engagement, etc., but in order to simplify the assembly operation of the opening and closing member, it is slidably attached to the attachment part. It is preferable to do this.

  Note that the magnetic attracting member does not need to protrude from the mounting portion, and the surface of the magnetic attracting member may be positioned substantially on the same surface as the mounting portion or at an internal position relative to the mounting portion. In order to effectively use the magnetic force of the magnetic attracting member, it is preferable that the mounting surface is substantially the same or protrudes.

  Further, the facing surface of one magnetic attracting member may be a flat surface or may have an uneven shape, and the facing surface of one magnetic attracting member faces the other magnetic attracting member. An uneven portion that can be fitted or inserted into the surface may be formed. Furthermore, if necessary, the opposing surface of at least one of the magnetic attracting members may be coated or coated with a resin (soft resin or the like) in order to reduce the attracting sound.

  The first magnet member and the second magnet member may be disposed on the pair of opening / closing members in a form in which different magnetic poles are adjacent to each other in the width direction of the pair of opening / closing members. That is, in the pair of rod-shaped members, the magnetic poles of the respective magnet members may be different in the width direction of the pair of rod-shaped members. Further, the magnet members may be opposed to each other with the opposite magnetic poles facing each other on the opposed surfaces of the pair of rod-shaped members. More specifically, different magnetic poles (N pole and S pole) are adjacent to each other in the width direction of the one rod-shaped member (or the width direction of the mounting recess), and the first magnet member is disposed on the one rod-shaped member. Are arranged, and different magnetic poles (N pole and S pole) are arranged adjacent to each other in the width direction of the other rod-shaped member (or the width direction of the mounting recess), and the second magnet member is arranged on the other rod-shaped member. The first magnet member and the second magnet are arranged with the opposite magnetic poles (the S pole for the N pole and the N pole for the S pole) facing the opposing surfaces of the pair of rod-shaped members. The members may face each other. Therefore, in the closing operation of the opening / closing member, it can be closed while positioning with certainty.

  The magnet member may be a single member, or may be composed of a plurality of magnet members disposed adjacent to or spaced apart from each other in the longitudinal direction and / or the width direction. The number of magnetic poles of the magnet member is not limited to two poles (N pole and S pole), but may be a plurality of poles such as four poles and six poles. In order to improve workability, it is preferable to use a bipolar electrode. In addition, the width of the N pole and the width of the S pole may be different but are usually the same in many cases.

  If necessary, the magnetic attracting member mounted on the mounting part may be positioned and fixed by fixing means (such as fasteners and adhesives), etc. Also good.

  In order to prevent the magnet member from being attached to the mounting portion in the wrong direction, a marker may be attached to the magnet member and / or the opening / closing member or the mounting portion (at least the magnet member). N pole and S pole) and the mounting direction or mounting position. For example, the end of the magnet member may be provided with a marker for indicating an arrangement site for the mounting portion of the opening / closing member, or the end of the magnet member may be provided with a marker for indicating the insertion start portion or the arrangement site of the mounting recess. Also good. You may give a marker to the side part (one side part or both side part corresponding to N pole and S pole) of the edge part of a magnet member. This marker may be attached to both the magnet member and the opening / closing member or the mounting portion. In this case, when the positions and types of the markers match (for example, when a common marker is located at the end), it can be determined that the magnet member has been properly inserted. Furthermore, the markers may be different types of markers (for example, markers of different colors, different characters, etc.) applied to both ends of the magnet member and / or the opening / closing member or the mounting portion. The type of marker is not particularly limited, and may be, for example, marking such as coloring or cutting, or display (character display) of an attachment site or an insertion start portion. For example, in order to display the N pole and S pole of the magnet member, an indication to that effect may be attached to at least one of the N pole and S pole of the magnet member.

  In the opening / closing member, at least one (both or one) of the pair of members is not necessarily required to have an attachment portion for attaching the partition sheet, but is often provided. This attachment part should just be formed in the non-opposing part of the rod-shaped member, and the side part (side wall) adjacent to the opposing surface of the member, the side part opposite to the opposing surface of the member ( You may form in the opening direction in the opening direction side surface or side wall. The attachment portion may be formed extending from the member. The cross-sectional shape in the thickness direction of the mounting portion is semicircular, polygonal (triangle, quadrangle (square, rectangle, trapezoid, etc.), pentagon, etc.), one or more end corners of the polygon are chamfered or It may be a cut shape or the like.

  The opening / closing member may include a pressing member for holding the partition sheet between at least one member of the pair of members. The partition sheet may be sandwiched between positioning portions (particularly, fitting portions), but is usually often sandwiched between portions (or regions) other than the positioning portions (particularly fitting portions). The partition sheet may be sandwiched between the opposing surfaces of the rod-shaped member (attachment portion and the like) and the pressing member, and at least one side portion (particularly both side portions) in the width direction of the rod-shaped member and / or the pressing member. You may provide the clamping part (or convex part) which can clamp a partition sheet | seat. The cross-sectional shape of the holding member may be a non-hollow cross-section (such as a U-shaped cross-section) or a hollow cross-sectional polygonal shape (such as a hollow cross-sectional square (cross-sectional hollow square, cross-sectional hollow rectangular, etc.)). May be. The pressing member may have a positioning portion that can be positioned with respect to at least one member. The form of the positioning portion is not particularly limited. For example, the positioning portion may be a locking or locking portion that can be locked or hooked to a rod-like member (attachment portion or the like). There may be. The positioning portion (particularly, the fitting portion) may be formed at a predetermined interval in the longitudinal direction of the pressing member, and extends in the longitudinal direction in order to be accurately and easily fitted and positioned with the rod-shaped member. May be formed. In particular, when the positioning portion (particularly, the fitting portion) is formed to extend in the longitudinal direction, it can be accurately and easily fitted and positioned with the rod-shaped member. The pressing member may be positioned (particularly fitted) with respect to the rod-shaped member. For example, the pressing member may be positioned (particularly fitted) with the opposing wall of the pressing member with respect to the pressed wall of the rod-shaped member. Usually, positioning (particularly, fitting) is often performed at a predetermined distance from the wall surface of the mounting recess.

  The opening / closing member may constitute a partition member for partitioning the space. In this partition member, the space may be partitioned along rails or guide members. That is, the opening and closing member is useful for forming a partition unit including a partition sheet attached to the attachment portion.

  The partition sheet can be composed of a resin film or sheet (soft resin sheet, etc.), paper, fabric (woven fabric (curtain, etc.), non-woven fabric, etc.), resin-impregnated fabric, plate (wood plate, metal plate, etc.), etc. You may comprise. Further, the partition sheet may be composed of a plurality of sheets and panels connected so as to be bendable, or may be composed of sheets and panels that can be folded (expanded) or stored (shrinked). The thickness of the partition sheet can be selected according to the application, and may be, for example, about 10 μm to 30 mm, preferably about 25 μm to 20 mm, and more preferably about 50 μm to 10 mm.

  The partition sheet may be attached to a rod-like member (attachment portion or the like), and may be attached by being sandwiched between the rod-like member or the attachment portion and the pressing member as described above. Adhesion, welding, screws, etc. It can be attached by various fixing means.

  If necessary, the partition sheet may be supported by a reinforcing support member at an appropriate position (or a plurality of positions) in the opening and closing direction. Usually, the partition sheet is supported by sandwiching the partition sheet in the middle of the partition sheet. There are many. Such a reinforcing support member may be composed of a pair of support members (poles), and the partition sheet may be sandwiched between the pair of support members, and the support member and a pressing member that can be pressed against the support member. The partition sheet may be sandwiched between the support member and the pressing member. The cross-sectional shape of the sandwiching surfaces of the pair of support members or the sandwiching surfaces of the support member and the pressing member may be linear or non-linear (such as irregularities). In particular, the sandwiching surface preferably has a symmetrical uneven surface. The cross-sectional shape of the uneven surface may be U-shaped (curved or wavy), V-shaped, U-shaped, etc., and is usually U-shaped or V-shaped (particularly U-shaped). There are many cases. If the cross-sectional shape of the uneven surface is U-shaped or V-shaped (particularly U-shaped), the partition sheet can be firmly held without being damaged. When the reinforcing support member is used, flapping of the partition sheet can be prevented, so that the opening / closing operation can be performed smoothly. In the case of a fabric or the like, it is also possible to prevent sagging. In particular, if the cross-sectional shape of the sandwiching surfaces of the pair of support members or the sandwiching surfaces of the support member and the pressing member is non-linear (such as a concavo-convex shape), the partition sheet can be firmly fixed and misalignment can be prevented. Furthermore, when the clamping surface has a symmetric uneven surface, it can be easily assembled without being erroneously assembled. The number of the reinforcing support members, the distance between the opening and closing members, the distance between the poles, and the like can be appropriately selected. In addition, you may use various fastening or fixing means, such as a screw, for attachment of each member as needed.

  Since the opening / closing member of the present invention has high magnetic attraction and can reduce the closing sound caused by closing, the space (factory work booth, clean room, warehouse; conference room; hotel room, banquet hall; school classroom, gymnasium) It can be used for partition units (partition curtains, partition panels, etc.) for partitioning theater stages; hospital rooms, operating rooms;
