Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a wire winding drum for winding various wires such as electric wire tubes and storing them.

[Prior art]

This type of wire winding drum is constructed by joining side plates to both ends of the winding drum by gluing or the like.

For this reason, when forming it, a gluing and drying process is required, making it troublesome to assemble. Furthermore, since the drum-shaped drum is provided to the user in an assembled manner, it is bulky and takes up a large volume when transported, stored, etc., resulting in inconvenience.

The object of the present invention is to provide a wire winding drum that is easy to assemble, can be assembled at any time by the user, does not require storage in a drum shape, and eliminates the drawbacks of conventional structures. It is something to do.

[Means for solving problems]

In the present invention, two parallel horizontal folding curves are formed through the folding margin, inside and outside, and furthermore, a locking claw piece is formed laterally on the side edge of the tip through a vertical folding curve along the side edge. a winding drum formed by winding a paper pattern formed by forming a plurality of connecting pieces formed at appropriate positions on both side edges of a rectangular body, at equal intervals to the folding margins of the connecting pieces, and two pairs of parallel insertion grooves with a width that allows the connection piece to be inserted,
The wire winding drum is composed of two side plates formed at corresponding positions to the connecting piece and having a winding hole bored in the center thereof.

[Effect]

For such a wire winding drum, first,
The paper pattern is wound to form a winding drum, and the connecting piece protruding from the side edge of the winding cylinder is folded by the locking claw piece at the tip of the connecting piece along a vertical folding curve, and then inserted into the insertion groove on the outside of the side plate. Insert it and bend it inward at the inner transverse bending curve,
Next, bend the tip along the outer transverse curve and insert it into the insertion groove inside the side plate. In the inserted state, the locking claw piece is naturally unfolded, and thereby comes into contact with the inner surface of the side plate and is locked so that the connecting piece cannot escape. By performing this operation on each connecting piece, the side plates are connected to both side edges of the winding drum, and the drum is completed.

In the present invention, since the drum is completed through this assembly procedure, the user can easily assemble the drum, and the drum can be stored in a disassembled state.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Here, reference numeral 1 denotes a paper pattern made of cardboard for the winding drum, and four connecting pieces 2 are formed at equal intervals on both side edges of the rectangular body. One of the connecting pieces 2 is formed at the extreme end of the paper pattern 1, and an overlap margin 3 is formed at the other end of the paper pattern 1.

The connecting piece 2 is formed with two parallel horizontal bending curves 4 and 5 in the circumferential direction, with a folding allowance 6 placed therebetween, and furthermore, on both sides of the end 7 at the tip beyond the folding allowance 6, Locking pawl pieces 9, 9 are formed to protrude laterally via vertical folding curves 8, 8 along the side edges. The connecting piece 2
has a tapered shape by making the folding margin 6 trapezoidal.

The paper pattern 1 is wound to form a winding drum x with the connecting pieces 2 arranged at equal intervals.

In order to maintain this rolled state, a locking piece 10 is formed to protrude from one end of the paper pattern 1 as shown in FIG.
may be formed. This locking piece 10
may be provided with laterally protruding claw pieces on both sides thereof in the same way as the above-mentioned locking claw pieces 9, 9.

Incidentally, even if the locking piece 10 and the insertion groove 11 are omitted as shown in FIG. 1, the wound state is maintained when held on the side plate y, which will be described later.

The side plate y is formed of a disk-shaped cardboard as shown in FIG. 1, and a winding hole 21 is bored in the center thereof. Further, a slit-shaped outer insertion groove 22 is formed at the circumferential position of the winding drum x at the same position as the protruding position of the plurality of connecting pieces 2 projecting from the side edge of the winding drum x. Further, an inner insertion groove 23 is formed at a position parallel to the outer insertion groove 22 and spaced apart from the folding margin 6. The outer insertion groove 22 is equal to the width of the inner transverse bending curve 4 and also the inner insertion groove 23.
is set to be approximately equal to or slightly wider than the width of the outer transverse bending curve 5.

Next, the means for connecting the winding drum x and the side plate y will be explained.

First, as shown in FIG. 3A, the locking claw pieces 9, 9 at the tip of the connecting piece 2 protruding from the side edge of the winding drum After inserting the end portion 7 into the insertion groove 22 on the outside of the side plate y. Next, as shown in FIG. 3B, the inner folding line 4 is used to make a mountain fold, and the end portion 7 is bent inward, and then the end 7 is made a mountain fold along the horizontal folding curve 5, and the insertion groove 2 is placed inside the side plate y. Insert into. In the inserted state, the locking claw pieces 9, 9 are naturally unfolded and spread out, so that they come into contact with the inner surface of the side plate y, and the connecting piece 2
is locked in such a way that it cannot be escaped. In this locked state, the folding allowance 6 appears on the outer surface of the side plate y between the insertion grooves 22 and 23. Further, the locking claw pieces 9, 9 are housed in the winding drum x, and there is no problem in winding up the wire tube.

In the embodiment described above, the locking claw pieces 9 are formed on both sides of the end portion 7, but they may be formed only on one side.

By performing this operation on each connecting piece 2, the side plates y, y are connected to both side edges of the winding drum x, thereby completing the wire winding drum z shown in FIG. 3.

[Effect of idea]

As mentioned above, the present invention provides the connection piece 2 of the winding drum x.
Since it is constructed by sequentially inserting the parts into the insertion grooves 22 and 23 of the side plate y, it can be easily and robustly assembled. Furthermore, the ease of assembly allows the user to perform the process. Therefore, it is only necessary to assemble it when necessary, and it can normally be stored with the winding drum x and side plate y. Therefore, it has excellent effects such as being less bulky to store and transport and easier to handle.
