Description

TECHNICAL FIELD The present invention relates to a screen that is suitably used when partitioning a space in a lounge or office.

Conventionally, a screen in which a plurality of screens are mechanically connected via a joint member is known (for example, see Non-Patent Document 1).

This type of screen system is used in many places because each screen can be arranged in an orderly manner without clutter, but in situations where screens can be attached and detached and arranged freely, it is difficult to insert and detach screens. This is a time-consuming process, and some kind of countermeasure is desired.

One solution to meet these demands is to embed magnets in the side edges of each screen so that they can move freely, and use the magnetic force of those magnets to connect adjacent screens so that they can be inserted and removed. It will be done. However, since this type of screen is used in an environment where it is exposed to the public, there is a problem in that it is relatively difficult to simply attach magnets without spoiling its appearance.

By the way, in the field of toys, toys have been developed in which magnets are buried in the edges of building block-like pieces and the magnetic force of the magnets connects multiple pieces for play. is difficult to apply to screens. That is, in the conventional magnet mounting structure, the piece is constituted by a pair of half members having a concave portion on the joining end surface, and the magnet is placed in the concave portion when the half members are joined. However, the screen is much larger than the toy pieces, and it is unrealistic to make it a half-split structure. Therefore, there is a problem in applying such a magnet mounting structure to a screen.

There is. Each of the frames 3 to 6 is made of a pipe material having a circular cross section, and specifically, is made of an aluminum pipe material which is a non-magnetic material. The right and left frames 3 and 4 are in an upright position, and screw insertion holes 3x, 4x, 3y, and 4y are provided in the hollow area CA side near the upper ends 3a and 4a and the lower ends 3b and 4b, respectively. ing. The upper frame 5 is in a horizontal position, and has hanging parts 51 extending downward at both the right and left ends, and screws are inserted into the hollow area CA side in the vicinity of the lower end 51a of both hanging parts 51. A hole 51x is provided. The lower frame 6 is in a horizontal position, and has upright portions 61 extending upward at both right and left ends, and screws are inserted into the hollow area CA side near the upper end 61a of both upright portions 61. A hole 61x is provided.

Then, as shown in FIGS. 5 to 7, the upper ends 3a and 4a of the right and left frames 3 and 4 and the lower end 51a of the hanging portion 51 of the upper frame 5 are connected by the upper frame connecting member 7A, As shown in FIG. 5, the lower ends 3b and 4b of the right and left frames 3 and 4 and the upper end 61a of the upright portion 61 in the lower frame 6 are connected by a lower frame connecting member 7B. As shown in FIGS. 5 to 7, the lower half of the upper frame connecting member 7A fits into the upper ends of the right and left frames 3 and 4, and the upper half of the upper frame It is a rod-shaped member that fits into the lower end of the hanging portion 51 of the frame 5, and is made of a non-magnetic synthetic resin. A female screw hole 71 corresponding to the screw insertion holes 3x and 4x of the right and left frames 3 and 4 is formed in the lower half of the upper frame connecting member 7A, and a female screw hole 71 is formed in the lower half of the upper frame connecting member 7A. A female screw hole 71 corresponding to the screw insertion hole 51x provided in the hanging portion 51 of the upper frame is formed in the portion. Then, the right and left frames 3, 4 and the upper frame 5 are rigidly connected by screwing the connection screws v into the corresponding female screw holes 71 from the screw insertion holes 3x, 4x, and 51x and tightening them. It is now possible to do so. Note that 73 is a positioning protrusion for positioning the upper frame connecting member 7A to the frames 3 and 4 during assembly.

Here, in this screen S1, the side edge S1a, that is, the outer half of the right and left frames 3 and 4 made of pipe material with a circular cross section, has a convex curved surface that continues smoothly on both the front and back surfaces, It includes a magnet holder 72 made of a non-magnetic material and connecting magnets M1 and M2 held by this magnet holder, and the magnet holder 72 holding the magnets constitutes the side edge S1a of the screen S1. The screen S1 is attached to the right and left frames 3 and 4 while maintaining the convex curved surface of the side edge S1a of the screen S1. The manner in which the magnet holder 72 is attached will be described below.

That is, in this reference example , magnet holders 72 extending into the corresponding right and left frames 3 and 4 are formed at the lower ends of the right and left pairs of upper frame connecting members 7A, respectively. A magnet accommodating chamber 72s that accommodates the reference magnet M1 is formed between the inner surface (more specifically, the inner circumferential surface 721a of the holder main body 721 described later) and the inner circumferential surfaces 3s and 4s of the frame. On the other hand, the lower frame connecting member 7B is obtained by vertically inverting the upper frame connecting member 7A described above, and the same or corresponding parts are given the same reference numerals and the description thereof will be omitted. Therefore, the lower magnet M2 is placed 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 peripheral surfaces 3s and 4s of the frame. A magnet housing chamber 72s that accommodates the magnet is formed.

Here, the mounting structure of the magnets M1 and M2 will be explained in relation to the magnet storage chamber 72s. As shown in FIGS. 4 to 7, this screen S1 is provided with a magnet storage chamber 72s at the edge where another screen S2 is to be connected, and magnets M1 and M2 for connection can be moved freely within the magnet storage chamber 72s. It is housed in At least a part of the inner wall surface (inner peripheral surface 721a of the holder main body 721) of the magnet storage chamber 72s is cylindrical, and the magnets M1 and M2 accommodated in the magnet storage chamber 72s form a cylindrical inner wall surface. It has a prismatic shape that allows two adjacent corners M1a and M2a to be in line contact at the same time. The magnets M1 and M2 of this reference example are quadrangular prism-shaped with four corners, with the part located between a pair of adjacent corners serving as the N pole, and the other adjacent pair being located between the corners. It is magnetized so that the part becomes the south pole. Note that since the lower magnet M2 has exactly the same shape as the basic magnet, the manner in which its corner M2a makes line contact with the inner wall surface of the magnet storage chamber 72s is not shown.

This screen S1 has a plurality of frames connected in a frame shape as described above, that is, right and left frames 3 and 4, an upper frame 5, and a lower frame 6. , 4 is provided with a magnet housing chamber 72s. The screen S1 of this reference example has a pair of right and left frame connecting members 7A that fit inside the butted right and left frames 3 and 4 and the upper frame 5, and these frame connecting members 7A are used. A magnet accommodating chamber 72s for accommodating the basic magnet M1 is formed. Further, this screen S1 has a pair of right and left frame connecting members 7B that fit inside the butted right and left frames 3 and 4 and the lower frame 6, and these frame connecting members 7B are used to A magnet accommodating chamber 72s for accommodating the lower magnet M2 is formed. As mentioned above, the frames 3 to 6 are made of non-magnetic pipe material having a circular cross section, and the inner circumferential surfaces 3s and 4s of the right and left frames 3 and 4 accommodate the magnets. It constitutes a part of the cylindrical inner wall surface of the chamber 72s.

To explain the structure described above from a different perspective, this screen S1 includes a magnet holder 72 made of a non-magnetic material, and connecting magnets M1 and M2 held by this magnet holder 72. , M2 is attached to the edge of the screen body 1. To be more specific, the screen body 1 has a frame structure mainly composed of frames 3 to 6, and a magnet holder 72 is attached to the right and left frames 3 and 4 that constitute the edges of the screen body 1. It is installed together with magnets M1 and M2. That is, 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 a magnet holder 72 is integrally provided with the frame connecting members 7A and 7B. ing. Specifically, the magnet holder 72 includes a partially cylindrical holder body 721 that protrudes from the end faces of the frame connecting members 7A and 7B and is attached to a part of the inner peripheral surface of the frames 3 and 4, and this holder body The end plate part 722 is provided at the protruding end of the frame connecting members 7A and 721 and cooperates with the frame connecting members 7A and 7B to restrict the vertical movement of the magnets M1 and M2. It is molded into. Thus, the magnet storage chamber 72s is formed by forming a part of the inner circumferential surfaces 3s and 4s of the partially arcuate frames 3 and 4 and an inner circumferential surface 721a of the holder main body 721 that faces the inner circumferential surfaces 3s and 4s. The upper and lower ends of the magnet housing chamber 72s are closed by the frame connecting members 7A, 7B and the end plate 722 of the magnet holder 72.

The mounting materials 2A and 2B attached to the screen body 1 described above will be explained as follows. The front covering material 2A stretched on one side of the screen body 1 and the back covering material 2B stretched on the other side are continuous on the outside of the frames 3 to 6 so as to form a bag shape as a whole. There is. That is, the front facing material 2A and the back facing material 2B are knitted, for example, as a bag-like knitted fabric in which the upper edge and both left and right edges are connected, and are placed over the screen body 1 from above to connect the lower edges. Accordingly, it is attached to the outside of the frames 3 to 6. The facing materials 2A and 2B of this reference example are knits made using the thread material 2s, and the poorly transparent portion 2x has a mesh-like structure in which the thread material 2s is woven relatively densely. In addition, the transparent portion 2y has a hole shape in which the thread material 2s does not exist. FIG. 8 shows an enlarged view of only the front facing material 2A existing in area X in FIG. That is, the front facing material 2A has a large number of hole-shaped light-transmitting parts 2y randomly scattered between difficult-to-light-transmitting parts 2x that form a continuous mesh structure. The back surface layer 2B has a configuration similar to the front surface layer 2A, and when viewed from a distance, both give the same impression, but the transparent portion 2y is randomly arranged relative to the poorly transparent portion 2x. Therefore, when the front and back surface layer portions 2A and 2B are precisely compared in detail, they have completely different pattern shapes.

<Other screen S2>
The other screen S2 is of an L-type having an L-shape in plan view, and includes a frame-shaped screen body 1 and a pair of facing materials 2A and 2B arranged on both sides of this screen body 1. It will be done.

The structure of the screen body 1 is that the upper frame 5 and the lower frame 6 are bent at right angles at the center, and that an adjuster 63 which is a grounding body is provided below the lower frame 6 in place of the legs 62. The only difference from the other screen S1 is that the lower frame 6 is bent, and that a weight plate 64 is provided on the bent lower surface side of the lower frame 6. Basically, it is constructed using the same concept as the one screen S1. has been done. The front and back facing materials 2A and 2B are also knitted into a bag shape and placed over the frame body in the same way as in the case of one screen S1, and the lower edges of the front and back facing materials 2A and 2B are connected to each other on the lower frame. It is attached to the frame body by connecting on the bottom side. Therefore, the same reference numerals are given to the parts that are the same as or correspond to those of one screen S1, and the description thereof will be omitted.

Although the grounding bodies of both screens S1 and S2 are of different types, their supporting 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 and M2 is the same). There is. In this reference example , the downward separation distance Z, which is the distance between the basic magnet M1 and the lower magnet M2 in both screens S1 and S2, is also set to be the same.

Also, in this screen S2, the side edges S2a, that is, the outer halves of the right and left frames 3 and 4 made of pipe material with circular cross sections, have smoothly continuous convex curved surfaces on both the front and back surfaces, and are non-contact. It is equipped with a magnet holder 72 made of a magnetic material and connecting magnets M1 and M2 held in this magnet holder, and the magnet holder 71 holding the magnets constitutes the side edge S2a of the screen S2. The screen S2 is attached within the right and left frames 3 and 4 while maintaining the convex curved surface of the side edge S2a of the screen S2. The manner in which the magnet holder 72 is attached is completely the same as that in the screen S1 described above, so the same or corresponding parts are given the same reference numerals and the explanation will be omitted.

<Effects of the first reference example >
With such a configuration, when the frame connecting members 7A, 7B are fitted into the frames 3, 4, the magnet holder 72 to which the magnets M1, M2 are attached can be placed into the frames 3, 4 at the same time. . Therefore, the magnets M1 and M2 can be easily disposed at predetermined positions within the frames 3 and 4 without increasing the number of parts. If the magnets M1, M2 and the magnet holder 72 are housed in the frame, the appearance of the screens S1, S2 will not be impaired. That is, in this reference example , the convex curved shapes of the side edges of the screens S1 and S2, which are formed around the outer half portions of the frames 3 and 4, are maintained as they are. Therefore, the screens S1 and S2 have exactly the same appearance as a screen without magnets.

In this reference example , the case where the frame connecting members 7A, 7B and the magnet holder 72 are manufactured by integral molding with resin was explained, but the frame connecting members and the magnet holder are made into separate bodies and made with screws, adhesive, etc. They may be joined integrally.
<<Second reference example >> (Figures 10 to 11)
A second reference example related to the present invention will be described with reference to FIGS. 10 and 11. Note that parts corresponding to those in the first reference example described above are given the same names and numerals, and detailed explanations are omitted.

As shown in FIG. 10, the screen S3 of this reference example includes a screen body 1 having a frame structure similar to the first reference example , and the screen body 1 forms a side edge S3a of the screen S3. A magnet holder B72 is installed in the right and left frames 3 and 4 together with magnets M1 and M2. In this reference example , the right frame 3 is formed by connecting an upper half 31 and a lower half 32 via a frame connecting member (not shown), etc., and the upper half 31 is connected to the upper frame 5. Further, the lower half portions 32 are each integrally provided with the lower frame 6. Further, the left frame 4 is also formed by connecting an upper half 41 and a lower half 42 via a frame connecting member (not shown), and the upper half 41 is connected to the upper frame 5, and the lower half 42 is connected to the upper frame 5. are provided integrally with the lower frame 6, respectively.

In the first reference example described above, the magnet holder was provided integrally with the frame connecting member, but the screen S2 of this second reference example has frames 3 and 4 as shown in FIG. Holes 3n and 4n are formed at predetermined locations, and a box-shaped magnet holder B72 is fitted into the holes 3n and 4n while holding the magnets M1 and M2. The holes 3n and 4n bored in the frames 3 and 4 are, for example, rectangular and open outward. The magnet holder B72 is box-shaped with a bottom, and has a size and shape that allows it to fit into the holes 3n and 4n of the frames 3 and 4 from the outside. As shown in FIG. 11, the magnet holder B72 has an outer wall B721 curved in a partially arcuate shape with the same diameter as the frames 3 and 4, and when the magnet holder B72 is fitted to the frames 3 and 4, The outer surface of the magnet holder B72, ie, the outer surface B72a of the outer wall B721, is flush with and continuous with the outer peripheral surfaces 3t, 4t of the frames 3, 4. B723 is a retaining protrusion protruding from the outer surface of both side walls B722 of the magnet holder B72. This protrusion B723 is inserted into the frames 3 and 4 using temporary elastic deformation of the member. Although FIG. 11 only shows the mounting structure of the magnet holder B72 holding the basic magnet M1 on the left frame 4, the mounting structure of the magnet holder B72 holding the basic magnet M1 on the right frame 3 is shown in FIG. The structure is symmetrical to that shown in FIG. Furthermore, the mounting structure of the magnet holder B72 holding the lower magnet M2 on the right and left frames 3 is completely the same as the mounting structure of the magnet holder B72 holding the basic magnet M1.

In the case of this reference example as well, the frames 3 to 6 assembled in a frame shape are wrapped with the front and back facing materials 2A and 2B as in the first reference example , so the side edge S3a of the screen S3 is It forms a convex curved surface that continues smoothly on both the front and back surfaces, and even when the magnet holder B72 is attached to the frames 3 and 4, the convex curved shape of the side edge portion S3a is maintained.

With such a configuration, the magnets can be placed in the frames simply by press-fitting the magnet holders holding the magnets M1 and M2 into the holes 3n and 4n provided in the frames 3 and 4. Therefore, the configuration can be simplified and an increase in manufacturing man-hours can be effectively suppressed.

In the case of this second reference example , it is essential that the magnet holder be made of non-magnetic material such as resin, but it is not essential that the frame be made of non-magnetic material such as aluminum. , it can also be applied to frames made of magnetic materials such as iron.

Further, in the examples shown in FIGS. 10 and 11, the magnet has the same square columnar shape as the magnet of the first reference example , but it is not necessarily limited to such a shape.
<< One embodiment of the present invention >> (Figures 12 to 13)
Here, one embodiment of the present invention will be described with reference to FIGS. 12 and 13. Note that parts corresponding to those in the first reference example described above are given the same names and numerals, and detailed explanations are omitted.

As shown in FIG. 12, the screen S4 of this embodiment includes a screen body C1 having a panel structure. That is, the screen body C1 is mainly composed of a panel C2, and a magnet holder C72 made of a non-magnetic material is fitted into a recess C2x formed in an edge C2a of the panel C2 together with magnets M1 and M2. ing. As shown in FIG. 13, for example, the edge C2a of the panel C2 has a convex curved surface with a semicircular arc cross section, and the recess C2x is formed by partially cutting out the edge of the panel C2. . The magnet holder C72 is box-shaped with a bottom and has a cross-sectional shape that matches the cross-sectional shape of the concave portion C2x. Therefore, the outer surface C72a of the peripheral wall C721 of the magnet holder C72 and the outer surface C2b of the edge C2a of the panel C2 are flush and continuous. Therefore, the side edge portion S4a of the screen S4 of this embodiment also forms a convex curved surface that is continuous with the front and back surfaces S4b, S4b, and even when the magnet holder C72 is attached to the panel C2, the side edge portion S4a The convex curved shape of portion S4a is maintained. Although FIG. 13 only shows the mounting structure of the magnet holder C72 holding the basic magnet M1, the mounting structure of the magnet holder C72 holding the lower magnet M1 is completely the same.

With such a configuration, the magnets M1 and M2 can be placed in the panel C2 simply by fitting the magnet holder C72 holding the magnets M1 and M2 into the recess C2x formed in the panel C2. Therefore, the configuration can be simplified and an increase in manufacturing man-hours can be effectively suppressed.

In the examples shown in FIGS. 12 and 13, the magnet has the same square column shape as the magnet of the first reference example , but the magnet is not necessarily limited to this shape.

Furthermore, it goes without saying that the outside of the panel to which the magnet holder is attached may be covered with an exterior material.
<< Third reference example >> (Figure 14)
A third reference example related to the present invention will be described with reference to FIG. 14. Note that parts corresponding to those in the first reference example described above are given the same names and numerals, and detailed explanations are omitted.

The screen S5 of this reference example includes a screen body (not shown) wrapped in a covering material D2, and a magnet holder D72 is fixed to the covering material D2. The magnet holder D72 is, for example, a bag-shaped thing made of non-magnetic cloth or the like, and is configured so that the magnet M1 can be inserted into the magnet holder D72 through an opening D72a formed at the upper end and held therein. It has become. This magnet holder D72 is disposed on the side edge S5a of the screen S5.

With such a configuration, the magnet M1 can be installed simply by sewing the magnet holder D72 to a predetermined location on the facing material D2. Therefore, in addition to being easy to manufacture, it is also possible to change the specification to one that does not have a magnet by simply replacing the covering material D2.

Note that the screen main body may have a frame structure or a panel structure.

Furthermore, the covering material is not limited to one that takes measures against moire as in the first reference example , and can be modified in various ways.

Further, in the example shown in FIG. 14, the magnet has the same square columnar shape as the magnet of the first reference example , but the magnet is not necessarily limited to such a shape.

Note that the present invention is not limited to the embodiments described above.

That is, as long as the magnet holder holding the magnet is attached to the side edge of the screen having a convex curved shape while maintaining the convex curved shape, various modifications may be made without departing from the spirit of the present invention. Even if it is modified, the most important effect of the present invention is to provide a screen in which connecting magnets can be easily and reliably attached to the side edges to be connected without spoiling the appearance. The effect of being able to do this can be obtained.
