Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective member made of corrugated cardboard for packaging furniture or equipment having a step on a top surface, such as a kitchen counter.

[0002]

2. Description of the Related Art Generally, a rising wall is provided on the top surface of a kitchen counter behind a work surface. As a protection member for protecting such a top surface, one shown in FIG. 6 is known. Have been. This protective member is composed of two blocks 5 of different lengths, each of which is made by laminating a large number of cardboard sheets.
By adhering 0 and 51, a tall portion 52 contacting the work surface and a low portion 53 contacting the rising wall are formed.

As shown in FIG. 7, a tall portion 55 and a tall portion 56 are formed in a corrugated tubular body 54 so that a tall portion 5 is formed.
It is also conceivable that a V-shaped reinforcing member 57 is inserted into 5 and a U-shaped reinforcing member 58 is inserted into the lower part 56.

[0004]

However, in the protective member having the above-mentioned laminated structure, it takes a lot of time to bond the corrugated cardboard sheet, and the protective member in which the reinforcing material is provided has a large number of parts and is difficult to assemble. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stepped protection member which is excellent in workability at the time of manufacturing and is easy to assemble.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a stepped cylinder in which a tall portion and a low portion are formed by a pair of side plates, a deck, a high step plate and a low step plate. In a protective member made of a cylindrical body, one end surface of the cylindrical body is covered with an end plate connected to the high step plate, and a folding piece connecting the end plate and each of the side plates is folded in half to form an inner side. Since the low step board is composed of a pair of abutting pieces connected to each side plate, and a bent piece connecting the inner ends of these two abutting pieces is folded in two and bent in the direction of the deck. is there.

[0007] This protective member can be easily manufactured from one corrugated cardboard sheet, can be easily assembled from a flat folded state, and has a cylindrical body which is held by a folded piece and a bent piece. , And have excellent rigidity.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the development board made of corrugated cardboard shown in FIG.
Are provided in a row, and the step direction is directed to the connecting direction. An end plate 3 is continuously provided on one edge of the high step plate 1, and each side plate 2 is provided.
And the end plate 3 are connected by a folding piece 4. Fold piece 4
Are formed with single pieces 4a and 4b via a half-cut ruled line 5 that bisects an angle formed by a ridge line between the side plate 2 and the end plate 3, and a through hole 6 is formed at an intersection between the ruled line 5 and each of the ridge lines. Is provided.

Each of the side plates 2 is formed with an extension 7 projecting from the other end of the high step plate 1, and an inner edge of each extension 7 is provided with a contact piece 8. The two contact pieces 8, 8 are connected by a bent piece 9, and the bent piece 9 is formed with a pair of single pieces 9a, 9b via a half-cut ruled line 10 orthogonal to the edge.

A deck 11 is connected to an outer edge of the one side plate 2 and a flap 12 is connected to an outer edge of the other side plate 2.
3 has an insertion hole 14 formed at the base of the flap 12 by cutting. A sealing piece 15 and a holding piece 16 are sequentially provided at the edge of the deck 11 located on the extension part 7 side, and a notch 17 is provided at the tip of the holding piece 16.

In order to assemble the development board, as shown in FIG. 2, the side plates 2 and 2 and the end plate 3 are erected with respect to the high step plate 1 and at the same time the folding piece 4 is folded in two along the ruled line 5. And fold it inward, and lay the pieces 4a and 4b together. At this time, the folded piece 4 is moved by the repulsive force of the cardboard.
Although it separates from the side plate 2 and the end plate 3, the presence of the through-hole 6 allows the cardboard to be easily bent without hindering the thickness of the cardboard.

Further, while folding the folded piece 9 along the ruled line 10, the corresponding pieces 8, 8 and the single pieces 9a, 9b are sequentially bent inward, and the single pieces 9a, 9b are overlapped. Folded piece 9
With the bending, the pieces 8, 8 approach each other to form the low step board 18.

Then, the flap 12 and the deck 11 are sequentially bent inward, and the insertion piece 13 is inserted into the insertion hole 14 to form a tubular body 19, and the opening end of the tubular body 19 is sealed by the sealing piece 15. At the same time, when the holding pieces 16 are inserted into the cylindrical body 19 and the cut pieces 17 hold the single pieces 9a and 9b,
As shown in FIGS. 3 and 4, a protection member having a tall portion 20 and a low portion 21 is completed.

To package the kitchen counter 22 shown in FIG. 5 using this protective member, a plurality of protective members are arranged in parallel on the top surface 23. At this time, the high step board 1 of the tall part 20 is brought into contact with the work surface 24, and the low step board 18 of the tall part 21 is brought into contact with the rising wall 25. Then, the cardboard sheet 26 is covered from above the protection member, and the front and rear portions thereof are bent downward along the end surface of the protection member.

The protective member is excellent in rigidity because the tubular body 19 is shaped by the folded piece 4 and the bent piece 9, and particularly,
In the tall portion 20, the folding piece 4 provided continuously to the side plate 2 and the end plate 3 exhibits a strong deformation preventing action against an oblique load acting in a direction in which the side plate 2 falls down. Therefore, the articles to be packaged such as the kitchen counter 22 can be reliably protected.

Further, since it can be easily manufactured from one corrugated cardboard sheet, and can be disassembled and folded flat, it can be easily assembled from the state without bulk when stored.

If the single piece 4a of the folding piece 4 is attached to the side plate 2 in advance, the assembly can be performed more quickly.

[0018]

As described above, the protective member according to the present invention can be easily manufactured from one corrugated cardboard sheet.
It can be easily assembled from a flat folded state.

Further, since the cylindrical body is held by the folded piece and the bent piece, it has excellent rigidity, and it is possible to reliably protect a packaged object such as a kitchen counter having a step.
