Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to improvement of hose bobbins displayed at storefronts and the like.

<Prior art and its problems> Conventionally, this type of hose bobbin has a structure shown in FIG. 4. However, since the connecting edges 2' and 3' of the conventional hose bobbin A' center plate 1' are simply overlapped and fixedly connected, the center core _a1 ' The hose B that is wound around the joint edge 2', 3' has marks of the overlapped step 23 that has occurred between the joint edges 2' and 3', that is, the step 23 that has occurred at a height corresponding to the thickness of the core component plate 1', and the product is damaged. devalue.

In addition, both side plates for both open ends of the center core a ₁ ′
The mounting structure for _A2 ' is such that the tabs 4 cut into both open ends of the center core _A1 ' are bent and attached to the inner surfaces of both side plates A2 _' , and the both side plates _A2 ' are attached to the center core. Since it is attached to A ₁ ′, it is wound around the center core A ₁ ′ and both side plates
Hose B that comes into contact with _A2 ' may also have marks from the step 24 created between the ear piece 4 and the inner surface of both side plates _A2 ', or the hose B may be rubbed and damaged by the corner of the step 24. These problems have caused problems, and there has been a desire for countermeasures among businesses that handle this type of hose bobbin.

Furthermore, in hose manufacturing factories and stores, hose bobbins A' for winding hose B cut to a predetermined length are stacked and stored in several tiers. The side plate _a2 ' of the hose bobbin A' is crushed by the load of the hose bobbins A' stacked in the third and subsequent rows, and as a result, not only the core _a1 ' protrudes as shown in Figure 5, but also
If the side plate _a2 ′ is torn from its deformed base,
Alternatively, the regularly wound hose B may become irregular and may not be able to be pulled out smoothly when being pulled out at a store or the like, resulting in poor handling.

<Problem to be solved by the invention> The technical problem to be solved by the invention is that there is no risk of the hose being damaged due to step marks or being rubbed against it, and moreover, when the hose is stacked in several tiers, the upper tier To provide a hose bobbin that protects and prevents deformation of a hose without worrying about crushing and deformation due to side loads.

<Means for Achieving the Technical Problem> The technical means taken by the present invention to achieve the above-mentioned problem is to roll one of the joining edges of the core component plate, which is wound into a cylindrical shape and serve as the core, to the core component plate. One step is formed lower with a step corresponding to the board thickness, and the other joining edge piece is superimposed on this stepped joining edge piece, and both joining edges are fixedly joined to form a cylindrical center core. A through hole having the same diameter as the outer diameter of the cylinder of the core is opened in both side plates provided with fixing devices at both open ends in the axial direction of the core,
The tabs cut and formed in the open ends of both sides in the axial direction of the core are protruded outside from the through holes of the both side plates, and are bent and attached to the opening outer peripheral surfaces of the through holes, so that the both sides plates are attached to both sides of the core in the axial direction. A fastening device is provided at the open end, and a fold that contracts in the axial direction is provided on at least one of the circumferences near the inner side of the side plates fastened to both sides of the core in the axial direction.

<Function> According to the above-mentioned technical means of the present invention, one of the joining edges of the core constituent plates is lowered by one step with a step corresponding to the thickness of the constituent plates, and the other side is lowered by one step. By overlapping the joining edges and making a fixed connection, the overlapping and fixed joining edges become flush with the spherical surface. In addition, holes with the same diameter as the cylinder diameter (outer diameter) of the core are formed in both side plates, and the ears at the open ends of both sides of the core are made to protrude outside through the holes. By bending and fixing it to the outer circumferential surface of the opening, the inner surfaces of the both side plates at the inner circumferential corners of the core and the both side plates become flat surfaces toward the outer circumferential edges thereof.

Furthermore, when the hose bobbins are stacked in several tiers and stored, the side plates of the first and second tier hose bobbins are pushed downward and crushed by the load of the third and subsequent tier hose bobbins. It moves by the cushioning action of the folds formed on the circumference. That is, the side plates of the first and second stage hose bobbins are prevented from being deformed independently by the parallel movement of the center core due to the cushioning action of the folds.

<Example> An example of the present invention will be described in detail based on the drawings. The hose bobbin A has a center core _A1 made of corrugated paper and fixing devices provided at both open ends of the center core _A1 . The central core _a1 is formed by forming one of the short side joint edges 2 and 3 of the strip-shaped component plate ₁ cut into a desired width and length to be one step lower, and the other side. A cylindrical shape having a desired diameter (outer diameter) is formed by overlapping and fixing the joint edges 3 of the cylinders.

The core component board 1 has one joint edge 2 formed one step lower by a step corresponding to the thickness of the component board 1 with an overlapping width with the other joint edge 3 over the entire length in the edge direction. Stepped joint edge 2. As a result, when the joining edges 3 are overlaid and fastened together, the joining edges 3 are joined on the same spherical surface without creating a step (see FIG. 2).

In addition, 4 in the figure indicates a number of side plates A ₂ formed by cutting into both open ends of the central core A ₁ and provided in a large number in the circumferential direction.
These are ear pieces for fastening.

The above-mentioned side plates _a2 are formed into a disk shape having a desired diameter, and are formed into a donut shape with a through hole 5 having the same diameter as the cylindrical diameter of the center core _a1 opened at its center.

Therefore, to attach the both side plates _A2 to the core _A1 , attach the tabs 4 cut into the open ends of both sides of the core _A1 to the both sides plates.
The protruding tabs 4 are bent and attached to the _outer surface of the opening of the through hole 5 and fixed, and the both side plates _A2 are attached to both open ends of the center core _A1 . A hose bobbin A is formed.

Therefore, in the hose bobbin A of this embodiment, there is no step on the outer circumferential surface of the center core _a1 and the inner surface of both side plates _a2 at the inner corners of the center core _a1 and both side plates _a2 , and the hose bobbin A to be wound is There will be no step marks or damage caused by rubbing.

6 in the figure is a fold formed on at least one circumference of the center core a ₁ near both open ends on which both side plates a ₂ are provided with fixing devices, and this fold 6 is formed in the cylindrical direction of the center core a ₁ . In order to provide a cushioning effect, one to several multi-stepped strips are arranged on the circumference of the center core _A1 on the inside of one of the side plates _A2 .
It is formed by bending into a so-called bellows shape.

Therefore, the side plates _a2 of the hose bobbins A in the first and second tiers, which are stacked in several tiers during storage etc., are pushed downward and crushed by the load of the hose bobbins A in the third and subsequent tiers. The core _a1 also shrinks in the cylindrical direction due to the cushioning action of the folds 6 (see Figure 3).

Therefore, depending on the load of the hose bobbins A in the third and subsequent stages, the side plates of the hose bobbins A in the first and second stages are
The movement in which a ₂ is deformed independently from the fixed base with the core a ₁ is absorbed and prevented by the contraction movement of the core a ₁ parallel to the cylindrical direction due to the cushioning action of the folds 6.

In the above embodiment, the fold line 6 was described in detail as being provided only on the circumference on one side of the open end of the center core _a1 , but the crease 6 was provided on the circumference near both open ends of the center core _a1 . It is also optional to provide one on one side of the open end of the center core _a1 , and several on the other side of the open end in a multi-tiered form. structure).

<Effects of the invention> Since the hose bobbin of the invention is constructed as described above, it exhibits the following effects.

One of the joint edges of the core component plates that configure the core in a cylindrical shape is a stepped joint edge formed one step lower with a step corresponding to the thickness of the component plate,
Since the other joining edge is overlaid on this stepped joining edge and fixedly joined, the joining edges at both ends of the center core component plate are overlapped and fixed on the same spherical surface to form a cylindrical center core. You can.

In addition, through holes with the same diameter as the cylinder diameter (outer diameter) of the core are formed in both side plates, and through these holes, the tabs cut into the openings on both sides of the core and integrally provided are protruded to the outside. Then, the tabs are bent and attached to the outer surfaces of both side plates at the opening periphery of the through hole, so that the both side plates are provided with fastening devices to the core, so that the inner surfaces of the both sides plates at the inner corners of the core and the both sides plates are attached. There are no steps created by the ears, and the surface is flat.

Therefore, it is possible to provide a hose bobbin that ensures the protection of the hose without the risk of reducing the commercial value of the wound hose, which would be damaged due to step marks or rubbing against the wound hose.

A crease is provided on at least one circumference of the inner core near both open ends on which both side plates are fastened, and a cushioning action that acts in the cylindrical direction is given to the inner core, so that it can be stacked in several stages. During storage, etc., the side plates of the first and second hose bobbins are pushed downward and crushed by the load of the third and subsequent hose bobbins, and in parallel, the center core also moves in the cylindrical direction due to the cushioning action of the folds. Shrink.

Therefore, there is no risk that the side plates of the first and second hose bobbins will be crushed and deformed below the base of the attachment to the core, and the cushioning action of the creases will always keep the core core parallel to the cylindrical direction. It is absorbed and protected by a contraction action.

Therefore, the intended purpose was achieved.
