Description

[Technical field]

[0001] The present invention relates to a partition unit that separates indoors from outdoors or divides an indoor space, and a pair of magnet members used therein. [Background technology]

[0002] Generally, partition units are widely known in which a strip-shaped magnet is provided at the end of a sheet-like or plate-like planar member, and the planar member is fixed in a closed state by the magnet. For example, the opening / closing member described in Patent Document 1 includes a pair of members that can face each other, and magnetically attracting members that are respectively disposed on the opposing surfaces of the pair of members and can be magnetically attracted to each other. In the pair of opening / closing members in Patent Document 1, only two poles, the N pole and the S pole, are adjacent in the width direction of the opposing parts, and further, on the opposing surfaces, the magnet members are opposed with their opposite magnetic poles (the S pole facing the N pole and the N pole facing the S pole) facing each other. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-177863 A Summary of the Invention [Problem to be solved by the invention]

[0004] According to the opening / closing member of Patent Document 1, the pair of members can be closed smoothly without misalignment. However, if the pair of members in the closed state are subjected to vibration or impact, causing the magnetically attracted member in an attracted state to misalign in the width direction, the magnetic poles (north pole against north pole, south pole against south pole) face each other on the opposing surfaces, causing the magnetically attracted members to repel each other and the opening / closing member to easily open.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a partition unit and a pair of magnet members in which the magnet members are not easily separated even if the magnet members are misaligned in the width direction. [Means for solving the problem]

[0006] The invention made to solve the above problem is a partition unit capable of partitioning a space. The partition unit of the invention includes a first magnet member having a strip shape elongated in the vertical direction, and a partition member. The partition member moves along a moving path and can approach or move away from the first magnet member in the thickness direction of the first magnet member. The partition member has a sheet-like or plate-like planar member extending along the moving path, and an end member provided along the edge of the planar member on the first magnet member side. The end member includes an end surface facing the first magnet member, and a strip-like second magnet member arranged on the end surface and connecting the end member to the first magnet member. The first magnet member and the second magnet member each have a strip-like magnetic pole pair of S poles and N poles arranged in 2 pairs of 4 rows in the width direction. The first magnet member and the second magnet member have magnetic poles opposite to the magnetic poles formed on the opposing sides of each other. In the partition unit of the present invention, by forming two pairs of magnetic poles, one south pole and one north pole, in the width direction of the first magnet member and the second magnet member, the magnet members are less likely to separate even if the magnet members are misaligned in the width direction, compared to when only two poles, an north pole and an south pole, are formed in the width direction of each magnet member.

[0007] In the partition unit of the present invention, the dimensions along the width direction of the magnetic poles formed on the ends in the width direction of the first and second magnet members are shorter than the dimensions along the width direction of the magnetic poles formed inside the ends in the width direction. As a result, even if the magnetic members are misaligned in the width direction, the attractive force between the magnetic poles formed on the inside between the magnetic members is stronger than the repulsive force between the magnetic poles formed on the inside between the magnetic members and the magnetic poles formed on the ends, making it more difficult for the magnetic members to separate.

[0008] In the partition unit of the present invention, at least one of the first magnet member and the second magnet member has a groove extending in the vertical direction and having a depth in the thickness direction between the S pole and the N pole of only one of the two magnetic pole pairs, which makes it easy to determine the orientation of each magnet member when arranging the magnet members on the end members.

[0009] The invention made to solve the above problem is a pair of magnet members including a first magnet member having a strip shape elongated in the vertical direction and a second magnet member having a strip shape elongated in the vertical direction and provided on a partition member capable of partitioning a space by moving a sheet-like or plate-like planar member along a moving path. In the pair of magnet members of the invention, the first magnet member and the second magnet member face each other in the thickness direction. The first magnet member and the second magnet member are each formed with a strip-shaped magnetic pole pair of S poles and N poles arranged in 2 pairs of 4 rows in the width direction. In the first magnet member and the second magnet member, magnetic poles opposite to the magnetic poles formed on the opposite sides of each other are formed. In the pair of magnet members of the invention, by forming two pairs of magnetic pole pairs of S poles and N poles in the width direction of the first magnet member and the second magnet member, the magnet members are less likely to separate even if a positional deviation occurs in the width direction of the magnet members compared to a case in which only two poles, N poles and S poles, are formed in the width direction of each magnet member. Effect of the Invention

[0010] According to the present invention, even if the magnet members are misaligned in the width direction, the magnet members are less likely to separate from each other. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments. In the drawings, the same or corresponding parts are designated by the same reference characters and the description will not be repeated.

[0013] [First embodiment] 1 is a schematic perspective view showing a partition system 10 according to a first embodiment of the present invention. The partition system 10 is used to separate indoors from outdoors or to partition an indoor space.

[0014] The partition system 10 includes a partition unit 100 and a rail 30. The partition unit 100 includes a pair of partition members 110 and 120. The rail 30 is an example of a moving path. The rail 30 is fixed to, for example, an indoor ceiling. In this embodiment, the rail 30 has a shape that extends linearly, but the shape of the rail 30 is not particularly limited. For example, the rail 30 may extend while curving. The partition members 110 and 120 are arranged side by side along the rail 30. The partition members 110 and 120 are attached to the rail 30 by hanging them in the up-down direction D1 via, for example, a runner member (not shown) so as to be movable along the rail 30. In the partition system 10, a threshold may be provided as a moving path, and the pair of partition members may move along the threshold.

[0015] FIG. 2 is a diagram showing the structure of a pair of partition members according to the first embodiment of the present invention. FIG. 3 is an enlarged view of the periphery of the magnet members of the pair of partition members. FIG. 3(a) shows the state in which the magnet members are separated from each other (FIG. 2). FIG. 3(b) shows the state in which the magnet members are connected to each other. The partition member 110 has a planar member 111 and an end member 112. The planar member 111 is a sheet-like or plate-like member extending along the rail 30 and the vertical direction D1. Examples of the planar member 111 include a curtain, an accordion curtain, a partition board, and a panel. The end member 112 is a member attached to an edge portion 111a of the planar member 111 on the partition member 120 side.

[0016] The end member 112 has a columnar portion 112a, an attachment portion 112b, and a magnet member M1. The columnar portion 112a is a hollow, substantially rectangular column extending in the vertical direction D1. That is, the columnar portion 112a has four outer peripheral surfaces including an end surface 112c facing the partition member 120. Each of the four outer peripheral surfaces has a long strip shape in the vertical direction D1. The attachment portion 112b is provided to protrude outward from a surface 112d opposite to the end surface 112c among the four outer peripheral surfaces of the columnar portion 112a. The columnar portion 112a and the attachment portion 112b are integrally formed by extruding an aluminum alloy, for example. The edge portion 111a of the planar member 111 is attached to the attachment portion 112b. Specifically, edge 111a of planar member 111 is held by a recess provided in surface 112d of columnar portion 112a and mounting portion 112b, and is fixed to mounting portion 112b by screws or the like.

[0017] The magnet member M1 is disposed on the end surface 112c and has a strip-like shape that is elongated in the vertical direction, the same as the end surface 112c. Hereinafter, the direction of the end surface 112c perpendicular to the vertical direction is also referred to as the width direction D3. For example, the magnet member M1 is a rubber magnet having flexibility. In general, the magnet member M1 is formed by molding rubber kneaded with magnetic powder. In this embodiment, the magnet member M1 is held on the end surface 112c by the mounting claws 113 provided on both sides of the end surface 112c at the four corners of the columnar portion 112a. Furthermore, the magnet member M1 may be attached to the end surface 112c by screws or the like in addition to the mounting claws 113. In this case, if the screws are disposed in the grooves S1 described later, the screw heads are unlikely to be exposed to the outside from the end surface Md2 (FIGS. 3 and 4) of the magnet member M1.

[0018] The partition member 120 has a planar member 121 and an end member 122. The planar member 121 is the same as the planar member 111 except that the attachment direction of the planar member 121 to the rail 30 is opposite to that of the planar member 111, and therefore a description thereof will be omitted.

[0019] The end member 122 is the same as the planar member 121 except that the mounting direction to the rail 30 is opposite to that of the planar member 121. The end member 122 has a columnar portion 122a the same as the columnar portion 112a, a mounting portion 122b, and a magnet member M2. The columnar portion 122a includes a strip-shaped end surface 122c that is long in the vertical direction D1 facing the partition member 110. The mounting portion 122b is provided so as to protrude outward from a surface 122d opposite to the end surface 122c. The edge portion 121a of the planar member 121 is attached to the mounting portion 122b. The magnet member M2 is disposed on the end surface 122c and has a strip-shaped shape that is long in the vertical direction, the same as the end surface 122c.

[0020] As the partition member 110 or the partition member 120 moves along the rail 30, the magnet members M1 and M2 move toward or away from each other while facing each other in the thickness direction D2 of the magnet member M1 and the thickness direction D2 of the magnet member M2. In this embodiment, the magnet members M1 and M2 are an example of a first magnet member or a second magnet member, respectively.

[0021] 4 is a diagram showing the magnet member M1 according to the first embodiment of the present invention. The magnet member M2 is the same as the magnet member M1 except for the magnetic poles formed thereon, so the magnet member M1 will be used as a representative for the explanation.

[0022] The magnet member M1 includes a body portion M11 having a substantially rectangular parallelepiped shape and protrusions M12 protruding in opposite directions from both end faces of the body portion M11 in a width direction D3. In this embodiment, the protrusions M12 are provided over the entirety of the body portion M11 in the up-down direction D1, but the protrusions M12 may be provided only in a portion of the body portion M11 in the up-down direction D1.

[0023] When the magnet member M1 is placed in the space formed by the end face 112c of the end member 122 and the mounting claw 113 (Figure 2), the mounting claw 113 covers the protrusion M12, thereby preventing the magnet member M1 from coming off the end member 122.

[0024] In the main body M11, two pairs of magnetic pole pairs P1 and P2 are formed in the width direction D3. In detail, in the main body M11, four rows of belt-shaped magnetic poles, each of which is an S pole, an N pole, an S pole, and an N pole, are arranged in order from one end of the main body M11 in the width direction D3 to the other end thereof, and extend in the up-down direction D1. In addition, in Figs. 1 to 4, the S pole and the N pole are distinguished by the presence or absence of hatching, but in reality, it is difficult to visually distinguish the S pole and the N pole. In other words, in the magnet member M1, two pairs of four rows of belt-shaped magnetic pole pairs of S poles and N poles are formed in the width direction D3. At this time, the N pole is formed on the protrusion M12 provided on one end face of the main body M11 in the width direction D3 where the N pole is formed, and the S pole is formed on the protrusion M12 provided on the other end face.

[0025] As shown in FIGS. 2 and 3, the magnet members M1 and M2 arranged opposite to each other in the thickness direction D2 in the partition unit 100 form magnetic poles opposite to the magnetic poles formed on the opposing sides.

[0026] For example, in the partition member 110, an end face Md2 (FIGS. 3 and 4) on one side of the magnet member M1 in the thickness direction D2 faces the end face 112c. Therefore, an end face Md1 (FIGS. 3 and 4) on the other side of the magnet member M1 in the thickness direction D2 faces the magnet member M2 arranged in the partition member 120. On the other hand, in the partition member 120, an end face Md2 (FIGS. 3 and 4) on one side of the magnet member M2 in the thickness direction D2 faces the end face 122c.

[0027] Therefore, the other end face Md1 (FIGS. 3 and 4) of the magnet member M2 in the thickness direction D2 faces the magnet member M1 arranged on the partition member 110. At this time, between the magnet members M1 and M2, a magnetic pole opposite to the magnetic poles formed on the opposing sides is formed. For example, an S pole is formed in a portion of the magnet member M2 opposing the portion of the magnet member M1 where an N pole is formed, and an N pole is formed in a portion of the magnet member M2 opposing the portion of the magnet member M1 where an S pole is formed.

[0028] Therefore, the magnet members M1 and M2 in the partition unit 100 are attracted to each other by the four rows of magnetic poles formed in the width direction D3. As a result, when the distance between the partition members 110 and 120 becomes shorter than a predetermined length, the magnet members M1 and M2 are magnetically attracted to each other and connected to each other (FIG. 3(b)). In detail, the magnet members M1 and M2 are attracted to each other by the magnetic poles formed on the end sides in the width direction D3 and the magnetic poles formed inside the end sides in the width direction D3 and connected to each other.

[0029] For example, if the partition member 110 or the partition member 120 suspended from the rail 30 is blown by the wind and subjected to vibrations or impacts, the lower side of the partition member 110 and the partition member 120 is more likely to shift in position in the width direction D3 than the upper side. At this time, since the magnet members M1 and M2 are provided with four rows of magnetic poles, even if the magnet members M1 and M2 shift in position in the width direction D3, they can be attracted by the magnetic poles formed on the end side in the width direction D3 and the magnetic poles formed inside the end in the width direction D3, so the magnet members M1 and M2 are less likely to separate than when only two poles, one row each of N poles and S poles, are formed in the width direction D3 of each magnet member.

[0030] Therefore, when the magnet members M1 and M2 are connected by magnetic attraction force, even if vibration or impact is applied to the partition unit 100, causing the magnet members to shift in position in the width direction D3, the magnet members are less likely to separate.

[0031] As shown in FIG. 4, in magnet member M1 and magnet member M2, the dimension d1 along the width direction D3 of the magnetic pole formed on the end side in the width direction D3 is shorter than the dimension d2 along the width direction D3 of the magnetic pole formed more inward than the end in the width direction D3.

[0032] In this way, by making the dimension d1 on the end side in the width direction D3 shorter than the dimension d2 on the inside in the width direction D3, even if the position of the magnet members is shifted in the width direction D3, the force of attraction between the magnetic poles formed on the inside in the width direction D3 between the magnet members is stronger than the force of repulsion between the magnetic poles formed on the inside in the width direction D3 and the magnetic poles formed on the end side, so that the magnet members are less likely to separate from each other. As an example, if the dimension d1 of the magnetic pole on the end side of the magnet member M1 is set to about 1 / 3 to about half of the dimension d2 of the inner magnetic pole of the magnet member M1, the force of attraction between the magnet members M1 and M2 becomes stronger. In this case, the distance until the same magnetic poles face each other between the magnet members M1 and M2 becomes longer than when the dimension d1 and the dimension d2 are the same, so that the tolerance of the position shift that can maintain the adhesion state can be increased. The dimension of each magnetic pole along the width direction D3 is not particularly limited, and the dimension d1 and the dimension d2 may be the same.

[0033] At least one of the magnet member M1 arranged on the partition member 110 and the magnet member M2 arranged on the partition member 120 has a groove S1 and a groove S2 formed therein.

[0034] The groove S1 is, for example, a triangular groove provided on an end surface Md1 of the magnet member M1, extending in the up-down direction D1 and having a depth in the thickness direction D2. The groove S1 is provided between two pairs of magnetic poles. That is, in the magnet member, four rows of magnetic poles are separated by the groove S1 into two rows in the width direction D3.

[0035] The groove S2 is, for example, a round groove provided on an end surface Md2 of the magnet member M1, extending in the up-down direction D1 and having a depth in the thickness direction D2. The groove S2 is provided only between the S pole and the N pole of one of the two magnetic pole pairs. In other words, the S pole and the N pole of only one of the two magnetic pole pairs in the magnet member are separated in the width direction D3. The provision of the grooves S1 and S2 makes it easier to determine the orientation of the magnet member when it is placed on the end member.

[0036] Furthermore, as shown in FIG. 4, when groove S1 and groove S2 are provided on surfaces facing opposite directions in the thickness direction D2, groove S1 or groove S2 creates a gap between magnet members M1 and M2 that are connected to each other, so that partition members 110 and 120 can be separated from each other with a small force.

[0037] [Second embodiment] 5 is a schematic perspective view showing a partition system 20 according to a second embodiment of the present invention. In the following, the second embodiment will be described in terms of differences from the first embodiment, and descriptions of the same aspects as the first embodiment will be omitted.

[0038] The partition system 20 includes a partition unit 200 and a rail 30. The partition unit 200 includes a partition member 210 and a magnet member M3. The partition member 210 is the same as the partition member 110 or the partition member 120 in the partition system 10 according to the first embodiment, and includes a magnet member M1 or a magnet member M2. The magnet member M3 is the same as the magnet member M1 or the magnet member M2. That is, when the partition member 210 includes the magnet member M1, the magnet member M3 is the magnet member M2. On the other hand, when the partition member 210 includes the magnet member M2, the magnet member M3 is the magnet member M1. That is, in this embodiment, the magnet member M3 is an example of a first magnet member, and the magnet member M1 or the magnet member M2 arranged in the partition member 210 is an example of a second magnet member.

[0039] The magnet member M3 is disposed on a wall surface W located at the end of the rail 30. The magnet member M1 or the magnet member M2 and the magnet member M3 face each other in the thickness direction D2. The partition member 210 on which the magnet member M1 or the magnet member M2 is disposed moves in the thickness direction D2 along the rail 30, approaching or moving away from the magnet member M3. When the distance between the partition member 210 and the wall surface W becomes shorter than a predetermined length, the magnet member M1 or the magnet member M2 and the magnet member M3 are magnetically attracted to each other and connected to each other.

[0040] As described above, the partition system of the present invention is not limited to the above-mentioned embodiment, and can be implemented in various aspects without departing from the gist of the invention. In addition, the components disclosed in the above-mentioned embodiment can be modified as appropriate. For example, some of the components shown in one embodiment may be added to the components of another embodiment, or some of the components shown in one embodiment may be deleted from the embodiment.

[0041] In addition, the drawings are mainly schematic illustrations of each component to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of drawing. In addition, the configurations of each component shown in the above embodiment are merely examples and are not particularly limited, and it goes without saying that various modifications are possible within a range that does not substantially deviate from the effects of the present invention.
