[0017] First Embodiment (Figs. 1 to 9) A first embodiment of the present invention will be described with reference to FIGS.

[0018] In this embodiment, the present invention is applied to a screen system SS formed by connecting two screens S1.

[0019] As shown in FIGS. 1 and 2 , this screen system SS comprises two screens S1 and S2, each with magnets M1 and M2 attached to its side edges. The screens S1 and S2 can be connected using the magnetic force of the magnets M1 and M2. Each screen S1 and S2 has a base magnet M1 at a common height H at least on its side edges. The "common height H" refers to the height of the base magnet M1 relative to the floor F, regardless of whether or not each screen S1 and S2 has a grounding body that contacts the floor F, and regardless of the type of grounding body. As will be described later, in this embodiment, the grounding body of one screen S1 is a leg 62, while the grounding body of the other screen S2 is an adjuster 63, and therefore, the types are different. The screens S1 and S2 in this embodiment do not have a magnet above the base magnet M1. Furthermore, both screens S1 and S2 have a lower magnet M2 offset a certain distance Z below the base magnet M1. Below, each of the screens S1 and S2 will be explained.

[0020] <One of the screens S1> One screen, S1, is a straight-type screen that is linear in plan view. As shown in FIGS. 1 to 4, it comprises a frame-shaped screen main body 1 and a pair of mounting materials 2A and 2B arranged on both sides of the screen main body 1. As shown in FIG. 8, each mounting material 2A and 2B comprises a random mixture of light-impermeable portions 2x that do not easily transmit light and light-transmitting portions 2y that do easily transmit light. That is, as shown in FIGS. 3 and 4, the screen main body 1 comprises a hollow area CA inside frames 3 to 6 that are arranged in a frame shape, and both mounting materials 2A and 2B are attached to the frames 3 to 6 so as to cover the hollow area CA. As shown in FIGS. 1 to 4, each mounting material 2A and 2B comprises a region 21 corresponding to the frames 3 to 6 that is composed of the light-impermeable portions 2x, and a region 22 corresponding to the hollow area CA that comprises a random mixture of light-impermeable portions 2x and light-transmitting portions 2y. The specific details will be explained below.

[0021] As shown in FIGS. 1 to 3 and 5 , the screen main body 1 is a frame-like structure including right and left frames 3 and 4, an upper frame 5 connecting the upper ends of the right and left frames 3 and 4, and a lower frame 6 connecting the lower ends of the right and left frames 3 and 4. The lower frame 6 is provided with a pair of right and left legs 62 as grounding members. Each frame 3 to 6 is made of a pipe material with a circular cross section, specifically, an aluminum pipe material, which is a non-magnetic material. The right and left frames 3 and 4 are in an upright position and have screw insertion holes 3x, 4x, 3y, and 4y near the upper ends 3a and 4a and near the lower ends 3b and 4b, respectively, on the hollow area CA side. The upper frame 5 is in a horizontal position and has hanging portions 51 extending downward from both right and left ends. Each hanging portion 51 is provided with a screw insertion hole 51x near the lower ends 51a on the hollow area CA side. The lower frame 6 is in a horizontal position and has upwardly extending upright portions 61 on both the right and left ends, and screw insertion holes 61x are provided on the hollow area CA side near the upper ends 61a of both upright portions 61.

[0022] As shown in FIGS. 5 to 7 , upper ends 3a, 4a of right and left frames 3, 4 are connected to lower end 51a of hanging portion 51 of upper frame 5 by upper frame connecting member 7A, and as shown in FIG. 5 , lower ends 3b, 4b of right and left frames 3, 4 are connected to upper end 61a of upright portion 61 of lower frame 6 by lower frame connecting member 7B. As shown in FIGS. 5 to 7 , upper frame connecting member 7A is rod-shaped and has a lower half that fits into the upper ends of right and left frames 3, 4 and an upper half that fits into the lower end of hanging portion 51 of upper frame 5, and is made of a non-magnetic synthetic resin. Female threaded holes 71 corresponding to screw insertion holes 3x, 4x of right and left frames 3, 4 are formed in the lower half of upper frame connecting member 7A, and female threaded holes 71 corresponding to screw insertion hole 51x provided in hanging portion 51 of the upper frame are formed in the upper half. The right and left frames 3 and 4 are rigidly connected to the upper frame 5 by threading and tightening connecting screws v through the screw insertion holes 3x, 4x, and 51x into the corresponding female screw holes 71. Reference numeral 73 denotes a positioning protrusion for positioning the upper frame connecting members 7A to the frames 3 and 4 during assembly. Magnet holders 72 are formed at the lower ends of the paired right and left upper frame connecting members 7A, extending into the corresponding right and left frames 3 and 4. A magnet accommodating chamber 72a for accommodating a reference magnet M1 is formed between the inner surface of the magnet holder 72 (more specifically, the inner circumferential surface 721a of a holder main body 721, which will be described later) and the inner circumferential surfaces 3s and 4s of the frames. The lower frame connecting member 7B is obtained by vertically inverting the upper frame connecting member 7A described above. The same or corresponding parts are designated by the same reference numerals, and their description will be omitted. Thus, a magnet accommodating chamber 72a for accommodating the lower magnet M2 is formed between the inner surface of the magnet holder 72 of the lower frame connecting member 7B (more specifically, the inner surface 721a of the holder main body 721 described later) and the inner surfaces 3s, 4s of the frame.

[0023] Here, the mounting structure of the magnets M1 and M2 will be described in relation to the magnet accommodating chamber 72a. As shown in FIGS. 4 to 7, the screen S1 has a magnet accommodating chamber 72a at an edge to which another screen S2 is to be connected, and the connecting magnets M1 and M2 are freely accommodated within the magnet accommodating chamber 72a. At least a portion of the inner wall surface of the magnet accommodating chamber 72a (the inner peripheral surface 721a of the holder main body 721) is cylindrical, and the magnets M1 and M2 accommodated in the magnet accommodating chamber 72a are prismatic, allowing two adjacent corners M1a and M2a to simultaneously make line contact with the cylindrical portion of the inner wall surface. The magnets M1 and M2 in this embodiment are rectangular prisms with four corners, and are magnetized so that the portion located between one pair of adjacent corners is the north pole and the portion located between the other pair of adjacent corners is the south pole. Since the lower magnet M2 has the exact same shape as the basic magnet, the manner in which its corner M2a makes line contact with the inner wall surface of the magnet accommodating chamber 72a is not shown.

[0024] As described above, this screen S1 has multiple frames connected in a frame shape, namely, right and left frames 3 and 4, an upper frame 5, and a lower frame 6, and magnet accommodating chambers 72a are provided within the right and left frames 3 and 4. The screen S1 of this embodiment has a pair of right and left frame connecting members 7A that fit within the butted right and left frames 3 and 4 and the upper frame 5, and these frame connecting members 7A are used to form a magnet accommodating chamber 72a for accommodating a basic magnet M1. The screen S1 also has a pair of right and left frame connecting members 7B that fit within the butted right and left frames 3 and 4 and the lower frame 6, and these frame connecting members 7B are used to form a magnet accommodating chamber 72a for accommodating a lower-level magnet M2. As mentioned above, the frames 3 to 6 are made of non-magnetic pipe material having a circular cross section, and the inner surfaces 3s and 4s of the right and left frames 3 and 4 form part of the cylindrical inner wall surface of the magnet storage chamber 72a.

[0025] To explain the above-described structure from a different perspective, the screen S1 includes a magnet holder 72 made of a non-magnetic material and connecting magnets M1 and M2 held by the magnet holder 72, and the magnet holder 72 holding the magnets M1 and M2 is attached to the edge of the screen main body 1. More specifically, the screen main body 1 has a frame structure mainly composed of frames 3 to 6, and the magnet holder 72 is installed together with the magnets M1 and M2 in the right and left frames 3 and 4 that make up the edge of the screen main body 1. In other words, the screen main body 1 has a frame structure in which a plurality of frames 3 to 6 are connected via frame connecting members 7A and 7B, and the magnet holder 72 is provided integrally with the frame connecting members 7A and 7B. Specifically, the magnet holder 72 includes a partially cylindrical holder main body 721 that protrudes from the end faces of the frame connecting members 7A, 7B and abuts against parts of the inner circumferential surfaces of the frames 3, 4, and an end plate 722 that is provided at the protruding end of the holder main body 721 and cooperates with the frame connecting members 7A, 7B to restrict the up and down movement of the magnets M1, M2, and is molded integrally with the frame connecting members 7A, 7B from synthetic resin. Thus, the magnet accommodating chamber 72a is formed between parts of the partially arc-shaped inner circumferential surfaces 3s, 4s of the frames 3, 4 and the inner circumferential surface 721a of the holder main body 721 that faces these inner circumferential surfaces 3s, 4s, and the upper and lower ends of the magnet accommodating chamber 72a are closed by the frame connecting members 7A, 7B and the end plate 722 of the magnet holder 72.

[0026] The mounting materials 2A and 2B attached to the screen main body 1 described above are as follows. The front mounting material 2A, stretched over one side of the screen main body 1, and the rear mounting material 2B, stretched over the other side, are connected outside the frames 3 to 6 to form a bag-like overall structure. That is, the front mounting material 2A and the rear mounting material 2B are knitted into a bag-like knitted fabric, for example, with the top edge and both left and right edges connected. The fabric is then placed over the screen main body 1 and attached to the outside of the frames 3 to 6 by connecting the bottom edges. In this embodiment, the mounting materials 2A and 2B are knitted using a yarn material 2s. The light-impermeable portions 2x have a mesh-like structure in which the yarn material 2s is knitted relatively densely, and the light-transmitting portions 2y have a hole-like structure where the yarn material 2s is not present. Figure 8 shows an enlarged view of only the front mounting material 2A present in region X in Figure 2. That is, the front covering material 2A has a mesh structure in which numerous hole-like light-transmitting portions 2y are randomly scattered among continuous light-impermeable portions 2x. The back surface layer 2B has a similar structure to the front surface layer 2A, and when viewed from a distance, the two give the same impression, but because the light-transmitting portions 2y are randomly arranged relative to the light-impermeable portions 2x, a detailed and accurate comparison of the front and back surface layers 2A and 2B reveals that they have completely different pattern shapes.

[0027] <The other screen S2> The other screen S2 is an L-type screen that is L-shaped in plan view and comprises a frame-shaped screen body 1 and a pair of mounting materials 2A, 2B arranged on both sides of the screen body 1.

[0028] The screen body 1 differs from the first screen S1 only in that the upper frame 5 and the lower frame 6 are bent at a right angle in the middle, that an adjuster 63 serving as a grounding body is provided under the lower frame 6 instead of the legs 62, and that a weight plate 64 is provided on the underside of the bent portion of the lower frame 6. The screen body 1 is basically constructed in the same way as the first screen S1. The front and back facing materials 2A and 2B are also woven into a bag shape, as in the case of the first screen S1, and placed over the frame body. The lower edges of the front and back facing materials 2A and 2B are connected to the underside of the lower frame, thereby attaching them to the frame body. Therefore, parts that are the same as or equivalent to those in the first screen S1 are designated by the same reference numerals, and their explanations will be omitted.

[0029] Although the grounding bodies of these two screens S1 and S2 are of different types, their support heights are the same. That is, at least the height position H of the basic magnet M1 of both screens S1 and S2 is set to be the same (so that the distance between the floor surface F and each magnet M1, M2 is the same). In this embodiment, the downward distance Z, which is the distance between the basic magnet M1 and the lower magnet M2 of both screens S1 and S2, is also set to be the same.

[0030] <Effects of the First Embodiment> With this configuration, the basic magnets M1 of each screen S1, S2 are located at the same height H, so adjacent screens S1, S2 can be connected by bringing the side edges of the screens S1, S2 closer together.The screens can also be separated by pulling them apart with a force that overcomes the magnetic force between the basic magnets M1.

[0031] In addition, in this embodiment, the magnets M2 in the lower rows of each screen S1, S2 are also at a common height position, so the height positions of the magnets M2 in the lower rows are also aligned, and the two screens can be reliably connected by the magnetic forces between the basic magnets M1 and between the magnets M2 in the lower rows.

[0032] <<Reference Example>> (Fig. 10-Fig. 11) As shown in FIG. 10, the screen system SS2 of this reference example includes a medium-height screen BS1, a screen BS2 that is shorter than the medium-height screen BS1, and a screen BS3 that is taller than the medium-height screen BS1.

[0033] These screens BS1 to BS3 have magnets M1 and M3 attached to their side edges, and the screens BS1 to BS3 can be connected together using the magnetic force of the magnets M1 and M3.

[0034] Each of the screens BS1 to BS3 has a basic magnet M1 at a common height position H on its side edge. The common height position H refers to the height position of the basic magnet M1 relative to the floor F, regardless of whether or not each of the screens BS1 to BS3 has a grounding body in contact with the floor F, and regardless of the type of grounding body. In this reference example, it is assumed that each screen is installed directly on the floor F, and the separation distance P between the floor F and the basic magnet M1 is set to be equal for each.

[0035] As shown in Figure 10, the short screen BS2 does not have a magnet above the base magnet M1. In contrast, as shown in the same figure, the medium screen BS1 and the tall screen BS3 each have an upper magnet M3 at a position offset by a certain upper distance Q from the base magnet M1.

[0036] Each of the magnets M1 and M3 may be a square prism rotatable about a vertical axis as described in the first embodiment, or may be in another shape.

[0037] With this configuration, the basic magnets M1 of each screen are located at the same height position H, so adjacent screens BS1 to BS3 can be connected by bringing the side edges of the screens BS1 to BS3 closer together, as shown in Figure 11. Furthermore, the screens BS1 to BS3 can be separated by pulling them apart with a force that overcomes the magnetic force between the basic magnets M1.

[0038] Furthermore, the upper magnets M3 of the medium-height screen BS1 and the tall screen BS3 are arranged above the basic magnet M1 at a fixed upper separation distance Q, so that the height positions of the upper magnets M3 are aligned, and the two screens BS1 and BS3 can be securely connected by the magnetic forces between the basic magnets M1 and between the upper magnets M3.

[0039] <<Second embodiment>> (Figs. 12 and 13) As shown in FIGS. 12 and 13, the screen system SS3 of this embodiment includes a tall screen CS1 and a screen CS2 that is shorter than the screen CS1.

[0040] These screens CS1 and CS2 have magnets M1, M2, M3 attached to their side edges, and the screens CS1 and CS2 can be connected together using the magnetic forces of the magnets M1, M2, M3.

[0041] 12, each of the screens CS1 and CS2 has a basic magnet M1 at a common height position H on its side edge. As in the other embodiments described above, the common height position H refers to the height position of the basic magnet M1 relative to the floor F, regardless of whether or not each of the screens CS1 and CS2 has a grounding body in contact with the floor F, and regardless of the type of grounding body. In the case of this second embodiment, it is assumed that each of the screens CS1 and CS2 is installed directly on the floor F, and the separation distance P between the floor F and the basic magnet M1 is set to be equal.

[0042] The tall screen CS1 has an upper magnet M3 positioned above the basic magnet M1 by a fixed upward distance R, and a lower magnet M2 positioned below the basic magnet M1 by a fixed downward distance T. The left and right pairs of lower magnets M2 are provided at the lower corners where the side edges and the bottom edge of the screen CS1 intersect. The width of the screen CS1 is set so that the distance U between the left and right magnets M2 provided at the lower corners is equal to the aforementioned downward distance T.

[0043] The low screen CS2 has a pair of left and right basic magnets M1 located at the upper corners where the side edges and top edge of the screen CS2 intersect, and a lower magnet M2 located a fixed downward distance T below the basic magnets M1. The pair of left and right lower magnets M2 are located at the lower corners where the side edges and bottom edge of the screen CS2 intersect. The width of the screen CS2 is set so that the distance U between the left and right magnets M2 located at the lower corners is equal to the aforementioned downward distance T.

[0044] Each of the magnets M1, M2, and M3 may be a square prism rotatable about a vertical axis as described in the first embodiment, or may be in another shape.

[0045] With this configuration, the basic magnets M1 of each screen CS1, CS2 are located at the same height H, as shown in Figure 13, so adjacent screens CS1, CS2 can be connected by bringing the side edges of the screens CS1, CS2 closer to each other. Furthermore, the screens CS1, CS2 can be separated by pulling them apart with a force that overcomes the magnetic force between the basic magnets M1.

[0046] Furthermore, according to this second embodiment, other screens CS1 and CS2 can be connected to both sides of the tall screen CS1 that has been laid on its side, simply by aligning the lower magnet M2 provided at one of the lower corners and the upper magnet M3 provided at one of the upper corners at the aforementioned common height position H. Figure 13 shows an example in which a tall screen CS1 of the same structure is connected to the left of the laid-on screen CS1 in a normal upright position, and a short screen CS2 is connected to the right.

[0047] <<Third embodiment>> (Figs. 14 and 15) As shown in FIGS. 14 and 15, the screen system SS4 of this embodiment includes a tall screen DS1 and a screen CS2 that is shorter than the screen DS1.

[0048] These screens DS1 and DS2 have magnets M1A, M1B, M2, and M3 attached to their side edges, and the screens DS1 and DS2 can be connected together using the magnetic forces of the magnets M1A, M1B, M2, and M3.

[0049] 14, each of the screens DS1 and DS2 has a first basic magnet M1A at a common height position H on its side edge. As in the other embodiments described above, the common height position H refers to the height position of the first basic magnet M1A relative to the floor F, regardless of whether or not each of the screens DS1 and DS2 has a grounding body in contact with the floor F, and regardless of the type of grounding body. In the case of this third embodiment, it is assumed that each of the screens DS1 and DS2 is installed directly on the floor F, and the separation distance P between the floor F and the first basic magnet M1A is set to be equal.

[0050] The tall screen DS1 has a lower magnet M2 located a certain downward distance T below the first basic magnet M1A, a second basic magnet M1B located above the first basic magnet M1A by the basic magnet separation distance V, and an upper magnet M3 located an even higher distance W above the second basic magnet M1B. The left and right pairs of lower magnets M2 are located at the lower corners where the side edges and bottom edge of the screen DS1 intersect. The width of the screen DS1 is set so that the separation distance U between the left and right magnets M2 located at the lower corners is equal to the aforementioned downward separation distance T. The aforementioned upper separation distance W is also set equal to the lower separation distance T.

[0051] The low screen DS2 has a pair of left and right basic magnets M1 located at the upper corners where the side edges and top edge of the screen DS2 intersect, and a lower magnet M2 located at a fixed downward distance T below the basic magnets M1. The pair of left and right lower magnets M2 are located at the lower corners where the side edges and bottom edge of the screen DS2 intersect. The width of the screen DS2 is set so that the distance U between the left and right magnets M2 located at the lower corners is equal to the aforementioned downward distance T.

[0052] Each of the magnets M1, M1A, M1B, M2 to M4 may be a square prism rotatable about a vertical axis as described in the first embodiment, or may be in another shape.

[0053] With this configuration, as shown in Figure 15, the first basic magnet M1A of the tall screen DS1 and the basic magnet M1 of the short screen DS2 are at the same height position H, so adjacent screens DS1 and DS2 can be connected by bringing the side edges of the screens DS1 and DS2 closer together.The screens DS1 and DS2 can also be separated by pulling them apart with a force that overcomes the magnetic force between the basic magnets M1A and M1.

[0054] Furthermore, according to this third embodiment, by simply laying a tall screen DS1 on its side and aligning the lower magnet M2 at one of its lower corners and the upper magnet M3 at one of its upper corners at the common height position H, other screens DS1 and DS2 can be connected to both sides of the laid-down tall screen DS1. Figure 15 shows an example in which a tall screen DS1 of the same structure is connected to the left of the laid-down screen DS1 in a normal upright position, and a short screen DS2 is connected to the right. Then, a tall screen DS1 of the same structure is placed on top of the laid-down screen DS1 in the same lay-down position, and a short screen DS2 of the same structure is placed on top of the short screen DS2. In this embodiment, the distance D between the lower magnet M2 of the tall screen DS1 and the edge of the screen DS1 on the side where this lower magnet M2 is installed is set to twice (2D) to be equal to the basic magnet spacing V, and is also set to be equal to the upper spacing W and the spacing U between the left and right magnets M2.Therefore, the height positions of one lower magnet M2 and the other lower magnet M2 of the upper, laid-over screen DS1 are the same as the second basic magnet M1B and upper magnet M3 of the tall screen DS1 in the normal upright position located to the left of them, and these screens DS1 can also be connected suitably.

[0055] <<Other embodiments>> The present invention is not limited to the above-described embodiment.

[0056] For example, all of the screens that make up the screen system may have upper-stage magnets above the base magnets. Even in this case, if all of the upper-stage magnets are positioned at a certain distance above the base magnets, the magnetic force of the upper-stage magnets as well as the base magnets can be used to connect adjacent screens.

[0057] In addition, the height position of the basic magnet may be set at any location, and the upward distance between the basic magnet and the upper magnet, and the downward distance between the basic magnet and the lower magnet may also be set to any value.

[0058] The distance between the left and right magnets at the bottom corners may also be set to any value. However, if the distance between the left and right magnets is set to be equal to the lower distance, another screen with the same structure in a normal upright position can be connected to the side of a screen that has been laid on its side, as in the second and third embodiments described above.

[0059] In addition, various modifications may be made within the scope of the present invention without departing from the spirit of the present invention. [Explanation of symbols]
