Abstract

PURPOSE:To reliably cushion and fix illuminating shades by using a simple corner protecting member made of corrugated board, reduce the production cost and enhance suitability of recycling a packaging material. CONSTITUTION:A corner protecting member 1 is a square-cylindrical cushioning member made by punching the cardboard of corrugated board and the like. A cut hole 30 connected to three adjacent faces 20 to 22 among four faces 20 to 23 constituting the outer circumference of a square cylinder is provided at the central part of the cylinder 5 to form six parted faces (20 to 22) and one continuous face 23. By this method, the square cylinder 5 is made foldable. Further, a tongue piece projecting from the continuous face in parallel therewith is provided at the central part of the continuous face 23 so as to be connected to the face, and flat surface parts 25, 26, whose top ends are projected from the square cylinder 5 when the tongue piece is folded at right angles with the continuous face 23, are provided on both sides of the tongue piece. respectively, so as to be connected to the piece. Thus, the appearance is good as the corner protecting member 1.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner protector for preventing a luminaire shade from moving and being damaged in a packaging box.

2. Description of the Related Art In a conventional packaging structure, in order to place and cushion a lighting shade, cushions such as styrofoam are placed at symmetrical corners of a lower packing 2'as shown in FIG.
The fixing member 40 is adhered to prevent the movement of the luminaire shade.

Since the above-mentioned conventional method is a method of adhering the cushioning / fixing member 40, the adhering work is complicated, and the packing 2'is bulky for transporting.
The efficiency of storage decreases and the cost increases. Also, cardboard 2'and Styrofoam 4 when discarding packing 2 '
Separation of 0 is not easy and is not suitable for recycling. An object of the present invention is to secure cushioning and fixing by using a simple corner protector made of corrugated cardboard, reduce cost, and improve recyclability of packing material.

[Means for Solving the Problems] The above object is to make a cut hole in three adjacent surfaces of a corrugated cardboard rectangular tube formed in accordance with a gap between a lighting equipment shade and a packaging box, and bend the remaining one surface as a continuous surface. It is possible. Further, a tongue piece that projects in parallel from the continuous surface is continuously provided over the bent portion of the rectangular tube, and a flat surface part that can be bent at right angles to the continuous surface on both sides of the tongue piece and that sufficiently projects from the rectangular tube is provided. It is achieved by arranging them in series.

The protective device of the present invention has a structure in which a square tube having a protruding tongue piece and a flat surface portion is bent from the central portion, so that the square tube portion of the protective tool when attached to a corner of a lighting equipment shade. Intervenes in the gap between the lighting equipment shade and the packaging box
In addition to performing the fixing function, the tongue protruding from the continuous surface across the bent portion of the protector is caught in the corner portion of the lower packing and the packaging box, so that the protector does not move laterally. In addition, the flat part that bends at a right angle from the continuous surface of the square tube part of the protective equipment and protrudes sufficiently is sandwiched between the lighting equipment shade and the lower packing, preventing the protective equipment from moving upward. it can.

Embodiments of the present invention will be described below with reference to FIGS. 1 is a development view of a corner protector according to the present invention, FIG. 2 is an assembled perspective view of the protector, FIG. 3 is a perspective view seen from a surface opposite to FIG. 2, and FIG. FIG. 5 is an exploded perspective view of the package, and FIG. 5 is a partial sectional view of the package. As shown in FIG. 1, the corner protector 1 is formed by punching a sheet of paperboard such as a corrugated board, and is formed by folding curves 10, 11, 12 that are parallel to the longitudinal direction.
The rectangular cylindrical portion in which the continuous surface 23 and the divided surfaces 20, 21 and 22 are formed and when bent along a folding curve, the divided surface 20 overlaps on the inside and the continuous surface 23 and the divided surfaces 21 and 23 form the outer periphery. It is 5. Here, the size of the rectangular tube portion 5 is set in the lateral direction composed of the dividing surfaces 20 and 22 in accordance with the space of the lighting equipment shade A and the packaging box 4 shown in FIG. The vertical direction constituted by 21 is set to be larger than the range where bending work can be easily performed. Next, as shown in FIGS. 2 and 3, the corner protector 1 has an angle at which the rectangular tube portion 5 can be bent at a substantially right angle as shown in FIGS.
A notch hole 30 extending over 22 is provided. Furthermore, continuous surface 2
A tongue piece 24 projecting in parallel with the continuous surface is continuously provided at the center of 3, and the tongue piece is divided to connect the notch hole 30 to fold curve 1.
5 is applied, and the folding curve 1 is on both the left and right sides.
Flat portions 25 and 26, which can be bent by 3 and 14, and are longer than the dividing surfaces 20 and 22, are continuously provided, and the tip corners thereof are cut into a shape that abuts when the rectangular tubular portion 5 is bent. There is. The corner protector 1 configured as above is shown in FIG.
Assembled as shown in FIG. 3 and using the rectangular tubular portion 5 by bending it at a substantially right angle along the folding curve 24, as shown in FIG. 4 and FIG.
First, the lower packing 2 having a rising portion around the bottom of the packaging box 4 is arranged, the protector 1 is inserted along a part of the corner of the packaging box 4, and the tongue piece 24 is attached to the packaging box 4 and the lower packing 2. Since it is fitted in between, the square tube portion 5 is securely held. Next, if the lighting equipment shade A is placed inside the rectangular tube portion 5, the flat parts 25 and 26 are sandwiched between the lighting equipment shade and the lower packing, and the corner protector may be displaced upward. No, the package is completed by finally covering it with the upper packing. As described above, even though the corner protector has a simple structure, the corner protector has a sufficient cushioning / fixing function, and the protector itself can be reliably fixed and prevented from moving. Further, even when the decoration a of the lighting equipment shade is made of a relatively soft material such as wood, the angle of the cut hole 30 is changed to secure a space at the corner portion where the divided surfaces of the rectangular tube come into contact with each other. By doing so, a sufficient protection effect can be exerted even against damage to the decorative corner portion due to transportation impact or the like.

According to the present invention, as the corner protector, a corrugated cardboard or the like is punched and formed into a rectangular tube shape, and the corner protector is bent from the center. Since it protects and protects the movement of the protector itself, it can be manufactured at a relatively low cost and the efficiency of transportation and storage is improved. Further, since the material is paper and no adhesion is required, there is an effect that it can be easily recycled.
