[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gasket used for a sash or the like, and a flexible long filament material such as a long slide fastener chain, which is wound around and conveyed, and has a length as necessary. The present invention relates to a bobbin made of laminated cardboard that is used when a portion is drawn and used.

[0002]

2. Description of the Related Art A bobbin made of laminated cardboard, specifically corrugated cardboard, is disclosed, for example, in Japanese Utility Model Laid-Open No. 2-4864.
It is known from, for example, Japanese Utility Model Publication No. 2-4865.
When using, the support shaft is inserted into both flanges and the support shaft is supported on the gantry.However, when carrying a bobbin wound with a wire rod, a packing string or band is used between both flanges. It was common to hang it and carry the string or band.

[0003]

However, when the bobbin is lifted by holding the packing cord or band, the cord or band is strained, and even if the filament is rolled up to the full height of the flange, the strained cord is tightened. Or the band bites into the flange, the outer periphery of the flange on which the cord or band is hung is bent inward, and when the filament material is rewound and used, the filament that is pulled out to the bent portion of the flange There was a problem that the material was caught and smooth rewinding was not possible. In addition, the unraveled strings and bands are not only waste, but also expensive to dispose of, which is uneconomical.

SUMMARY OF THE INVENTION The present invention solves the above problems and provides a bobbin which can be lifted easily without hanging a cord or a band and which can ensure the safety of lifting.

[0005]

The solution means of the present invention is a bobbin in which flanges made of laminated cardboard are also provided at both ends of a barrel portion formed of laminated cardboard in a tubular shape, and shaft holes are provided in both flanges. A gripping portion formed by cutting a part of the flange into a tongue shape is provided on both flanges, and the cut surface of the gripping portion is cut to form an uneven edge.

As another solution, in a bobbin in which flanges made of laminated cardboard are also provided at both ends of a cylindrical body made of laminated cardboard and shaft holes are provided in both flanges, both end edges of the body portion Are bonded to both flanges, and a reinforcing piece of laminated cardboard that reinforces the shaft hole is bonded to the inner surface of both flanges, and the outer peripheral edge of both flanges is formed into an uneven edge. It is preferable that a gripping portion formed by cutting a part of the gripper into a tongue shape is provided, and the cut surface of the gripping portion cut out is formed on an uneven edge.

[0007]

[Function] Since the flange is provided with a gripping portion cut in a tongue shape, when the bobbin is transported, the tongue portion of the gripping portion is pushed into the body by a finger so that the tongue piece is positioned inside the flange. Since the insertion portion of the grip portion is formed by being pushed and bent, a finger is put into the insertion portion and lifted. Moreover, since the cut surface of the grip portion is formed on the uneven edge, when the finger is inserted into the insertion port of the grip portion, the uneven edge is touched, but the uneven edge is easily bent by the pressure of inserting the finger. Therefore, even if the finger is rubbed, it can be safely lifted without damaging the finger.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention is a shaft in which a laminated cardboard flange is similarly provided at both ends of a hollow laminated cardboard body portion around which a filament is directly wound, and a support shaft is passed through the center portions of both flanges. A hole is provided, and further, a grip portion formed by cutting a part of the hole into a tongue shape is provided on the flange, and a cut surface of the grip portion cut is formed at an uneven edge.

As another embodiment, in addition to the structure of the above-described form, a joint piece protruding from the body is adhered to the flange to integrally connect the body and the flange, and also to the outer peripheral surface of the flange. Even if the outer peripheral surface of the flange is touched by the hand, it is formed on the uneven edge so as not to damage the hand and enhance the safety.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring specifically to the drawings, as shown in FIGS. 1 and 2, corrugated cardboard is used as laminated cardboard, and a corrugated cardboard formed into a band shape is wound and adhered to form a cylindrical body. 1 is formed, and both ends of the body portion 1 are provided with a number of axial cuts at their ends in the circumferential direction, and the cut portions are bent outward to radially project. The joining piece 2 is provided.

The flange 3 is also made of corrugated cardboard and has a circular shape larger than the diameter of the body 1, and a shaft hole 4 is formed in the center of the flange 3.
A reinforcing piece 5 having a circular hole having the same diameter as that of the shaft hole 4 is bonded to the rear surface of the flange 3 to reinforce the shaft hole 4.

The above-mentioned means for attaching the flange 3 to the body 1 is such that the joint pieces 2 of the body 1 are flanged 3 by an adhesive.
It is integrated by adhering to the surface side having the reinforcing piece 5.

In the above bobbin, a pair of grips 6 is provided on both flanges 3, respectively.
Is a part corresponding to the inner space of the body part 1 of the flange 3, but it should be as close as possible to the shaft hole 4 so that the pair of grips 6 face each other with respect to the shaft hole 4. To be installed.
Further, the structure of the grip portion 6 is such that the flange 3 is cut in a U-shape, and the line cut along the left and right portions is
A notch is formed so as to be parallel to a center line orthogonal to the axis of the body part 1, and further, one end of the notch of the left and right parts closer to the shaft hole 4 is continuously cut to form a tongue shape. Since the tongue-shaped cut is formed in this manner, the uncut portion of the tongue, that is, the portion continuous with the flange 3 is bent toward the inside of the body portion 1 so that the flange 3 is finger-tipped. There is an insertion port 7 into which can be inserted.

Moreover, the cut line formed by cutting as described above is not a straight line but is cut in a zigzag shape so as to form the uneven edge 8. The uneven edge 8 is formed by cutting a large number of ridges in a continuous state, and is also formed with a fine ridge like a blade of a wood saw for woodworking. A large mountain shape like a saw blade that cuts the pillars of a building is not suitable because the waist is strong and the fingers are easily hit and easily damaged.

Although the grip portion 6 is formed by cutting the flange 3 into a U-shape, the shape is not necessarily limited to this shape, and although not shown, the tongue is formed by cutting a part of an ellipse. It may be formed in a piece shape, or may be formed in a tongue shape by cutting with the upper side or the lower side of the trapezoid left.

The outer peripheral edge of the flange 3 also has a grip portion 6
Similarly to the above, it is preferable to provide the uneven edge 8.

Due to the above structure, when the bobbin around which the linear member 9 is wound is lifted, both grips 6 provided on both flanges 3 are lifted by fingers, but when the fingers are hooked, the grips are gripped. By pushing the tongue-shaped portion of 6 that is cut, the tongue-shaped portion is bent into the body 1 as shown in FIG. 3, and the finger may be inserted into the opening 7 thus opened. . Moreover, when the finger is inserted, the edge of the insertion opening 7 is formed on the uneven edge 8, so that even if the finger comes into strong contact, each mountain shape of the uneven edge 8 is a fine mountain shape as described above. It is easy to push and bend, and it can be safely inserted and lifted without being damaged even if it is touched by a finger.

When using the linear member 9 wound on the bobbin, as shown in FIG. 4, the support shaft 10 is inserted into the body 1 through the shaft hole 4, and the support shaft 10 is mounted on a mount (not shown). ) Is used in the same manner as the conventional one, but even if the flange 3 is touched or rubbed by fingers during handling, the flange edge is also provided with the uneven edge 8, so that there is no danger of damage and safety. Is to hold.

[0019]

In the bobbin according to the present invention, since the grips are provided on both flanges, it is not necessary to hang a packing string or band on the flanges as in the conventional case, and the bobbin can be held by the grips. Even if it is lifted, there is no problem such as bending the outer circumference of the flange, and even if it is made of laminated cardboard, the wound linear material can be smoothly rewound.

In addition, since the cut edge for forming the grip portion on the flange is provided with the uneven edge, when the finger touches the uneven edge, the mountain portion of the uneven edge is crushed into a bent state, Since the cut edge is not sharp and rounded, it can be lifted without pain and scratches even if the finger rubs.

Further, the body portion is bonded to the flange through the joining piece, the reinforcing hole made of laminated cardboard of the same quality as the flange is provided in the shaft hole provided in the flange, and the grip portion similar to the above is provided, and the flange is provided. If it is a bobbin that has an uneven edge on the outer peripheral edge of, since no materials other than laminated cardboard are used,
When it is regenerated after use, it is not necessary to select it, and the processing operation becomes easy.

Further, as described above, since the outer peripheral edge of the flange is provided with an uneven edge, even if a finger touches or rubs the outer periphery of the flange during handling, it is not damaged and the handling is performed safely. Like
