DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a core material made of a substantially cylindrical long steel pipe. Reference numeral 2 denotes a rubber fitting in which a convex portion 3 is provided in a substantially central portion on the front surface side and an arc shape is formed on the rear surface side, and between the flange portions 4 and 4 provided on the lateral side of the convex portion 3. A plurality of belts 5 whose lengths can be adjusted are attached to the core material 1 at predetermined intervals so as to attach the attachments 2.

Denoted by 6 are fitting grooves formed in the arcuate back surface of the fixture 2 along the axial direction, and rod-shaped temporary magnets 7 are fitted in the fitting grooves 6, respectively. It will be done.
8 is a long hole 9 formed in the convex portion 3 of the fixture 2 in the axial direction.
A notch provided on the front surface of the convex portion 3 so as to communicate with
The notch 8 is set to have a width that allows the end of the film material 10 made of Teflon or the like to be engaged.

Denoted at 11 is a concave groove formed along the axial direction on the upper surface of the convex portion 3 of the fixture 2, and locking portions 12 are provided inwardly on both side surfaces thereof. Reference numeral 13 denotes a rod-shaped locking body fitted and mounted in the groove 11, and the mounting of the locking body 13 allows the end of the film material 10 to be held by the notch 8.

Although this embodiment has the above-mentioned configuration,
Next, a case where the film material 10 is wound around the core material 1 using this will be described.

First, as shown in FIG. 1, the fixture 2 to which a plurality of belts 5 are attached is inserted into the core 1, and the length of each belt 5 is adjusted to fix the fixture 2 to the core 1. At this time, since the magnets 7 ... Are provided on the back surface of the fixture 2, this allows the fixture 2 to be attracted and fixed to a desired position of the core material 1, and thus the careless position can be provided. There is an advantage that it can be used for convenience of fastening work of the belt 5 to the core material 1 such that deviation and drop can be avoided. Also, the fixture 2
Since is made of rubber, it has the flexibility of being widely applicable to the core material 1 having various outer diameters.

Next, after the end portion of the film material 10 is engaged with the notch 8 and the long hole 9 from the side portion of the fixture 2 in the axial direction, the locking body 1 is provided.
When 3 is pressed into the recessed groove 11 of the fixture 2 from above, the locking body 12 is fitted and mounted in the locking portion 12 of the recessed groove 11, whereby the notch 8 is pressed and closed. As a result, the end portion of the film material 10 is firmly and reliably held under pressure. In this state, the film material 10 is wound around the core material 1.

Thus, since the film material 8 can be attached to the core material 1 very easily in this way, a series of winding operations of the film material can be efficiently performed.

Further, since the structure of the fixture 2 and the like is very simple, there is an advantage that it can be manufactured at low cost.

On the other hand, when the film material 10 unwound from the core material 1 in order to stretch the film material 10 is removed from the fixture 2,
By removing the locking body 13 from the recessed groove 11 of the fixture 2 as described above, the sandwiched state of the film material 10 by the notch 8 can be easily released and the film material 10 can be separated from the core material 1.

Because of the ease of such a series of removal work, work at a high place is not complicated and can be performed safely and promptly. Therefore, the film material 10 may be damaged. Therefore, there is a great advantage that a good quality of the film material 10 can be secured.

In the above embodiment, the core material 1 and the mounting tool 2 are constructed separately, and the belt 5 is used to mount the mounting tool 2 on the core material 1. The mounting means is by no means limited to this, and it is of course possible to fix the mounting tool 2 to the core material 1 to integrally configure it.

Further, in this embodiment, since the magnet 7 is provided on the back surface of the fixture 2, there is an advantage that it is greatly useful for the work of attaching the fixture 2 to the core material 1. It does not necessarily have to be provided, and may be provided as needed.

Further, the fixture 2 provided on the core material 1 does not necessarily have to be formed in a long shape as in the above-mentioned embodiment, and the fixture 2 is formed in a relatively short dimension depending on the shape of the film material 10 and the like. However, a plurality of the core members 1 may be attached to the core member 1 at a predetermined interval, which is advantageous in that the removal of the film member 10 becomes easier.

Further, although the fixture 2 is made of rubber in this embodiment, the material is not limited to this, and the notch 8 may have any specific shape. In short, the fixture 2
It suffices that the film member 10 engaged in the notch 8 is attached to the recessed groove 11 so that the film material 10 can be held by the notch 8.

In addition, the core 1, the fixture 2 and the locking body 1 thereof
Designs of concrete shapes such as 3 can be arbitrarily changed within the scope intended by the present invention.

[0024]

As described above, according to the present invention, the notch into which the end portion of the film material is inserted by mounting the locking body in the groove provided in the fitting can sandwich the film material. Therefore, compared to the conventional one in which the binding of the Nanron tape is used as the attachment means for both, the attachment work can be performed very easily, which is a special effect.

Moreover, even in the work of stretching the film material at a high place, if the locking body is removed from the groove of the fixture, the sandwiched state between the notch and the film material is released and the film material is released. Since the core can be separated from the core material, there is a remarkable effect that this series of operations can be performed extremely safely and efficiently.

In addition, due to the ease of the cutting operation, even if the film material is inflated by a gust of wind at a high place, the film material is inconveniently damaged as in the conventional case. There is also the effect that good quality can be maintained.

Further, since the fixture and the like according to the present invention have an extremely simple structure, there is also a practical advantage that they can be manufactured at low cost. (Note) Teflon in the detailed description of the device is a registered trademark.
