Description

[Detailed description of the invention] [Industrial application field] This invention relates to an improvement of a winding plate for winding tape, string, thread, etc.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, a winding plate for winding this type of tape or the like has been made by punching paper or plywood or a molded product of synthetic resin, and the shape of the corner support member of the winding plate is a right angle. As a result, when the wound tape or the like is rewound, there are problems such as creases remaining in the tape or the like or damage to the tape, which impairs subsequent use. Therefore, it is possible to form the corner support member in an arc shape, but in this case, the above problem cannot be solved unless the winding plate itself is made thick and the diameter of the arc is increased. The weight becomes heavier and the cost of materials increases, leading to higher costs. Furthermore, in the case of molded products such as synthetic resins, it is necessary to prepare molds for each type of thickness, which poses problems in terms of workability and cost. In addition, as shown in Fig. 4 and Fig. 5 (see Utility Model Publication No. 11-6165), a cylindrical edge body e with grooves d formed in the vertical direction on both edges of the narrow center of a thin plate-shaped bobbin a. A bobbin winder A that is removably fitted with
is provided. In this bobbin A, in order to prevent the cylindrical edge e from falling off the bobbin a, the width of the groove d of the cylindrical edge e should be made narrower than the thickness of the bobbin a, so that the cylindrical edge e can be moved by the elastic restoring force. It is necessary to have a configuration in which the pincushion a is sandwiched. Here, if the width of the groove d is made wide, the cylindrical edge body e can be easily fitted onto the bobbin winding a, but it is likely to come off easily and there is a risk that it will fall off or be lost during handling. Furthermore, if the width of the groove d is made narrow, it becomes difficult for the pincushion a to fit into the groove d of the cylindrical edge body e, and if an attempt is made to forcefully fit the pincushion a into the groove d, the edge of the pincushion a may be damaged.

This idea was made in view of the above circumstances,
In addition to preventing bends in the tape, etc., the main body of the winding plate and the corner resting member are manufactured separately, and they are combined appropriately and easily, so that a thin winding plate is used, and the weight is reduced. It is an object of the present invention to provide a winding plate that is lightweight, can be manufactured at low cost, and allows corner stopper members with different diameters to be arbitrarily selected to meet various demands.

[Means for Solving the Problems] The winding plate according to the invention is provided with protruding prevention portions at both ends of the left and right edges of the winding plate body for winding tape, string, thread, etc., and the above-mentioned A corner support member, which has an arcuate shape on one side of its outer periphery and a longitudinal fitting groove on the other side, is placed between the slip-off prevention portions on each side edge, and is inserted into the fitting groove in the side edge. A detent is formed near the side edge of the slip-off prevention portion to prevent the corner support member attached to the side edge from returning.

〔Example〕

An embodiment of this invention will be described based on the drawings.
FIG. 1 is a perspective view showing the winding plate of this embodiment, FIG. 2 is an exploded plan view, and FIG. 3 is an exploded front view. This winding plate consists of a winding plate main body 1 and a corner support member 2. The winding plate 1 is made of cardboard, and as shown in the figure, has a substantially rectangular shape with parallel upper and lower sides, and both left and right sides are cut out in the shape of a flat cup to form side edges 3, 3, and both ends of each side edge 3, 3 are cut out in the shape of a flat cup. A slip-off preventing portion 4 is formed in the tape to prevent the wound tape from slipping off. A detent 5 is formed near the side edge 3 of the slip-off preventing portion 4 to prevent the corner support member 2 attached to the side edge 3 from returning (FIG. 2). The corner support member 2 is formed by providing a longitudinal fitting groove 2c in a pipe made of synthetic resin (FIGS. 1 and 3).
Then, the corner support member 2 fits the side edges 3 of the winding plate main body 1 into the fitting grooves 2c, and the left and right side edges 3,
3 (Fig. 1). Further, the corner support member 2 is attached to each side edge portion 3, and its both ends are locked by the detents 5 (FIG. 1).

According to the winding plate of the above embodiment, since the outer periphery of the corner support member 2 is formed in an arc shape, the wound tape etc. will not be damaged and will not be creased even when rewound. Further, since the winding plate main body 1 is made of cardboard, it is light in weight and the material is inexpensive. Moreover, cardboard can be manufactured by punching, making mass production possible and reducing costs. Furthermore, even if cardboard is incinerated after use, it does not pose a pollution problem. Also, when attaching the corner support member 2 to the side edge 3 of the winding plate body 1, the fitting groove 2
C can be fitted with one touch, making assembly easy and workable.Moreover, since both ends of the corner rest member 2 are locked with detents 5, the corner rest member 2 can be attached to the side of the winding plate body 1 without coming off. The edge portion 3 is securely fixed, and there is no fear of separation or falling off, and there is no fear of loss. In addition, the larger the diameter of the corner rest member 2, the less the tape etc. will bend, so corner rest members 2 of various diameters can be prepared and easily changed to one with an appropriate diameter as needed. . In addition, since the outer diameter of the corner support member 2 is larger than the thickness of the winding plate main body 1, when a tape or the like is wrapped, a gap is formed between the tape, etc. and the surface of the winding board main body 1, so that the tape has good air permeability. etc. will not get wet.

In the above embodiment, cardboard was used as the material for the winding plate main body 1, but plywood, plywood, synthetic resin, etc. may also be used. Further, although synthetic resin is used as the material for the corner rest member 2, it may be made of paper or wood. Further, the corner support member 2 may be adhered to the side edge portion 3 of the winding plate main body 1 by adhesive. Further, although the shape of the winding plate main body 1 is also formed into a rectangular shape, it is not limited to this.

"Effects of the invention" The winding plate according to this invention has a pull-out prevention part protrudingly provided at both ends of the left and right edges of the winding plate body for winding tape, string, thread, etc., and at each side edge. is located between the slip-off prevention portion, and a corner support member having an arc shape on one side of its outer periphery and a longitudinal fitting groove on the other side fits the side edge portion into the fitting groove. A detent is formed near the side edge of the slip-off prevention part to prevent the corner support member attached to the side edge from returning, so that the tape or the like does not get bent. First, since a thin winding plate body is used, the weight is light and the cost is low. In addition, since both ends of the corner rest member are locked with detents, the fitted corner rest member is securely fixed to the side edge, and once fitted, the corner rest member will not come off and will not fall off. There is no fear of losing the tape, so
The winding plate for winding strings, threads, etc. can always be kept in good condition, and when attaching the corner support member to the side edge of the winding plate body, the width of the groove into which the corner support member is fitted must be made sufficiently wide. Since it can be widened, it can be fitted into the fitting groove with one touch without damaging the side edges of the winding plate main body, and assembly is easy and workability is also good. Furthermore, since the winding plate body and the corner support member are manufactured separately and then combined, it is possible to easily manufacture products of various sizes and diameters, meeting various demands. In addition, since the outer diameter of the corner support member is larger than the thickness of the winding plate body, a gap is created between the wound tape, etc. and the surface of the winding plate body, so the tape, etc. may be soiled by moisture, etc. do not have. Furthermore, since the slip-off prevention part is formed, there is an effect that the wound tape etc. will not slip off.
