A permanent magnet 71 is accommodated in the long member 45 in which the permanent magnet 70 is positioned so as to attract the permanent magnet 70, and the permanent magnets 70 and 71 attract each other to make the magnet sheet 2 It is designed to maintain the winding condition stably.
According to the sixth embodiment, the winding device 1 in the non-use state can be magnetically attached to the magnetic member 4 by the permanent magnet 7 provided on the end bar 6 (see FIG. 8a). The permanent magnet 70 can be separated from the outer periphery of the magnet sheet 2 to expand the binding band 49, and the magnet sheet 2 wound as it is on the cylindrical winding tool 43 can be expanded onto the magnetic bonded body 4 (FIG. 8b) reference).
In other words, when the magnet sheet 2 is expanded, it is not necessary to once take off the winding device 1 in the non-use state from the magnetic object 4, and conversely, when making the winding device 1 into the non-use state Also, the magnet sheet 2 can be wound around the cylindrical winding tool 43 while the end bar 6 is magnetically attached to the magnetic attachment body 4.

Next, the winding device 1 of the seventh embodiment shown in FIG. 9 will be described. The binding band 49 of the present embodiment is constituted by a surface fastener, and the base end 49 a of the binding band 49 exceeds the end bar 6. The length of the portion of the binding band 49 which protrudes outward beyond the end bar 6 is fixed to a position where it is protruded to the magnet sheet 2 side, as in the sixth embodiment, the winding device in the non-use state The length of the outer circumference of 1 is set to be less than one turn, so that the projecting portion does not pass between the magnet 4 and the end bar 6.
With such a configuration, when the binding band 49 is wound around the winding device 1 in a non-use state, the leading end polymerizes with the base end 49a in the required range, and the polymerized parts adhere to each other by the surface fastener. It is supposed to
According to the seventh embodiment, as in the sixth embodiment, the winding device 1 in the non-use state can be magnetically attached to the magnetic member 4 by the permanent magnet 7 provided on the end bar 6 (FIG. 9a) Further, the magnetic sheet 2 wound around the cylindrical winding tool 43 can be developed on the magnetic bonded body 4 by further peeling off the tip end of the binding band 49 from its end 49a (FIG. 9b) reference).
In the case of the configuration of the seventh embodiment, since the binding band 49 protrudes to the magnet sheet 2 side more than the end bar 6, when the magnet sheet 2 is in use, a part of the binding band 49 is magnetized with the magnet sheet 2 It will be located between the clothes 4.
For this reason, since there is a possibility that wrinkles may occur in the magnet sheet 2 at the overlapping position of the bundling band 29, for example, the surface of the overlapping area of the bundling band 29 in the magnet sheet 2 is blackened It is desirable to make it unusable as a screen.

In contrast to the sixth and seventh embodiments described above, the binding band 49 of the winding device 1 of the third embodiment shown in FIG. 5B is one turn around the outer periphery of the magnet sheet 2 when the winding device 1 is not used. As described above, the part wound around the end bar 6 is wound so as to pass between the end bar 6 and the magnetic member 4.
As a result, when the magnet sheet 2 wound around the cylindrical winding member 43 is developed on the magnetic object 4, the binding band 49 is allowed to pass between the end bar 6 and the magnetic object 4. If not, the magnet sheet 2 can not be expanded.
In other words, the end bar 6 can not be expanded while being magnetically attached to the magnetic attachment body 4, and conversely, the magnet sheet 2 is wound while the end bar 6 is magnetically attached to the magnetic attachment body 4. I can not do it either.

FIG. 10 shows a stand 80 of the winding device 1. In the sixth and seventh embodiments, the end bar 6 is magnetically attached to the magnetic member 4 to hold the winding device 1. On the other hand, in the present embodiment, the winding device 1 is held by the magnetic attachment 4 using the stand 80.
The erecting tool 80 can be manufactured by cutting out a single iron plate into a required shape and bending it, and a magnetic attachment portion 81 magnetically attached to a magnetic attachment body, and a magnetic attachment portion 81 And a support portion 82 which protrudes forward from and supports the winding device 1.
A permanent magnet 83 is provided on the surface of the magnetic attachment portion 81 on the side of the magnetic attachment 4 so that the stand 1 can be magnetically attached to the magnetic attachment 4.
The support portion 82 is composed of a flat portion 82a formed on the magnetic object 4 side, and a spread portion 82b formed to spread obliquely from the flat portion 82a, and the flat portion 82a and the spread portion 82a are spread. The non-use winding device 1 is accommodated in a space formed between the portion 82b and the portion 82b.
Further, a hook 82c for engaging the overturn preventing member 84 formed of a chain-like member such as a ball chain is formed substantially at the center of the expanded portion 82b.

With such a configuration, when the permanent magnet 7 of the end bar 6 does not have a sufficient magnetic force, it is possible to hold the winding device 1 on the magnetic attachment 4 using the stand 80. It has become.
Specifically, the stand 80 is magnetically attached in advance to the required position of the magnetic object 4, and the winding device 1 in the non-use state in which the magnet sheet 2 is wound up in this state is used as the support portion 82. To accommodate.
At this time, by accommodating the end bar 6 toward the flat portion 82a of the support portion 82, the wound magnet sheet 2 uniformly contacts the spread portion 82b, and the winding device 1 is stably held. Can be held.
Thereafter, the fall prevention member 84 is attached to the hook 82c formed in the two spread parts 82b, so that the winding device 1 in the non-use state can be held so as not to come off.
Here, for example, when the winding device 1 is held on a blackboard or a white board as the magnetized object 4, the winding is performed by a choke receiver provided at the lower part of the blackboard or a marker receiver provided at the lower part of the white board. The removing device 1 may be supported from below.

The hinge connection is not limited to the hinge connection using the magnet sheet 2 described above, the resin hinge using synthetic resin, or the tape 41, and the long members 5, 25, 45, 55, 65 may be used. If it is possible to form a stable cylindrical winding tool 43 by bringing the contact portions at both ends in the circumferential direction of the respective elongated members into contact with each other naturally when assembling in the circumferential direction, a configuration of hinge connection is obtained. It doesn't matter. A hinge may be used as an example of another hinge connection.
In the second to fifth embodiments, although the rubber magnet corresponding to the rubber magnet 8 of the first embodiment is omitted, it is needless to say that a rubber magnet may be provided if necessary.
Furthermore, although two, three or eight long members forming the cylindrical winding member are used in the above embodiment, other members may be used, and the cylindrical members may not necessarily be equally spaced in the axial direction. It does not need to be the structure divided into these, and you may use the elongate member divided | segmented into non-equal intervals. Furthermore, the cylindrical member need not be hollow, and may be solid. Further, in the above embodiment, the cylindrical winding members 3, 23, 43, 53, 63 and the magnet sheet 2 are integrally connected. However, each cylindrical winding tool may be detachably separated from the magnet sheet 2. Even in this case, it is apparent that the above-described effects of the present invention can be obtained when each tubular winding tool is used while attached to the magnet sheet 2.
