Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a corner protection piece for protecting a corner part of an article having corners and/or protecting a person from injury due to a collision with the corner part.

[Conventional technology]

There are countless cornered items around us, including furniture, fixtures, electrical appliances, daily necessities, machinery and equipment, and more. When packaging, transporting, or storing these items, cardboard packaging boxes are generally used, but if they require particularly careful handling, Styrofoam corner protectors are often used in combination. be done. However, this type of foamed resin protective piece is used in a pre-molded state, which is inconvenient for transportation and storage, and due to cost considerations, it cannot be used unless it is mass-produced. In particular, in the case of large furniture, fixtures, mechanical equipment, and other articles that are not suitable for packaging, the corners of the articles need to be more carefully protected. However, until now there has been no flexible protective piece on the market that can be used regardless of the size of the object, and sellers and transporters of the object have no choice but to take the time and effort to purchase a dedicated protective piece. Currently, the protective pieces are manufactured in-house. Incidentally, a corner protector has been proposed in which a cross-shaped crease is added to square corrugated paperboard and one of the four small squares defined by the crease is cut out (Utility Model No. 49-11). (Refer to Publication No. 33079), not only does it require the use of a locking means such as duct tape or adhesive for assembly, but it is also difficult to apply to rounded corners because the material is hard. Therefore, it can be said that the development of corner protection pieces that are easy to handle and versatile is one of the important issues in the field of packaging and packing of articles. The above is a situation seen from the point of view of the person handling the object, but in reality, from the perspective of the person using the object, a person, especially a young child, may head over a corner of furniture, etc. There is always a chance of being hit and injured or of getting clothing caught in the corner and tearing it. Therefore, it is preferable to protect dangerous corners as much as possible to prevent such danger.

[Problem that the idea aims to solve]

The present invention simplifies the wrapping and packaging of goods by developing a corner protection piece that is easy to handle, does not require locking means such as adhesive tape, and is versatile. The purpose is to provide a simple means of protection from harm caused by collisions.

[Means to solve the problem]

(Summary) In order to achieve the above object, the corner protection piece according to the present invention is a square plate-like body made of a flexible cushioning material, and the plate-like body extends in all directions from its center. A corner protection piece characterized by having a cross-shaped fold reaching the center of each side and further comprising the following three types of slits; A first slit extending toward one side of the plate. a second slit extending from the center of the slit to the center of a 1/4 small square adjacent to the slit; Another 1/ separated by a slit
4. A third slit extending parallel to the slit from the center of the small square and reaching the periphery of the small square. Below, we will outline the main points related to the idea. (Basic shape) Referring to Figures 1 and 2 showing the original shape of the protective piece and its usage, the protective piece 1 of the present invention has a plate-shaped cushioning material that is basically square, with its central part ₀ It is divided into four small squares S ₁ to S ₄ by the mutually orthogonal folds 2 and 2', and a first slit 3 is bored along the boundary line between the adjacent small squares S ₁ and S ₂ . Furthermore, it is characteristic that two slits are added in addition to the first slit 3. The upper second slit 6 is formed so as to reach the center p of the small square _S1 from the center of the first slit 3. Further, the third slit 7 is formed in the small square
It is applied parallel to the slit 3 from the center q of the small square S ₂ adjacent to S ₁ and reaching the edge of the small square S ₂ . Therefore, it is laid out somewhat geometrically.
Then, the slit 6 is parallel to the fold line 2, and the slit 7 is parallel to the fold line 2', and their length is 1/2 that of the slit 3. The width of each slit 3, 6 and 7, at least at its entrance, is approximately the same as the thickness of the piece of cushioning material used, and more preferably is wedge-shaped, with the width gradually decreasing towards the back. preferable. (Flexible Cushioning Material) The protective piece of the present invention can be made of existing flexible plate-shaped cushioning materials, such as the above-mentioned laminated foam cushioning material (registered trademark ``Air Cap''), foamed plastic sheet, sponge rubber sheet. Manufactured from materials such as The above "air cap" is an example of a preferable cushioning material that has appropriate flexibility and stretchability in addition to cushioning properties. Corrugated paper is difficult to bend in the direction intersecting the core, so it is not preferred for design purposes. (Other additions) The main protection piece is as follows.

As described in the [Operation] section, since it has its own engaging function, adhesive tape or other auxiliary locking means are unnecessary. However, if desired, apply or adhere adhesive or adhesive tape to one surface and/or back surface of the other of the two 1/4 small squares sandwiching the slit 3, and then cover the adhesive surface with release paper. It can be covered with. Fold the above protective piece 1 in the same direction along the fold lines 2 and 2', and place the half piece _4b1 of the flap 4b on the slit 3 side under the half piece _4a1 of the flap 4a on the fold line 2a side. ; By inserting the half pieces 4b ₂ of the flap 4b on the side far from the slit above the half pieces 4a ₂ of the flap 4a on the side far from the fold 2a, the protective device 5 is in the stable engaged state shown in FIG. is obtained. If the material of the protective piece 1 has a certain degree of elasticity and/or the width or shape of the slit 6 is appropriate, this engaging operation can be performed almost with one touch, and the slits to be engaged can be easily connected to each other. Since they mesh and exert frictional force on each other, there is no risk of disassembly even without using a locking means such as adhesive tape. Moreover, there is no need to remove release paper, which is required when adhesives or double-sided adhesive tapes are used together. In addition, as shown in Figure 3, the slit 6
If an arcuate or diagonal notch 8 is further provided at the entrance, the engagement operation between the flaps 4a and 4b can be carried out even more quickly.

【Example】

Hereinafter, the content of the present invention will be explained in more detail with reference to the accompanying drawings, but the examples are strictly for illustration purposes and do not mean a limitation on the spirit of the invention. Embodiment 1 FIG. 4 shows an example in which the protective piece 1 of the type shown in FIG. 3 is constructed using an "air cap." The width l of the opening edge of the slit 3 is made larger than the thickness m of the material. In this example, as already explained, by engaging the slits 6 and 7, an excellent corner protector is formed. Embodiment 2 FIG. 5 shows an example in which wedge-shaped slits are carved as the slits 6 and 7 in the protective piece 1 made of corrugated paper in the format shown in FIG. 1. The width l of the opening edges of the two slits is also set to be considerably larger than the thickness m of the first slit.

[Effect of the idea]

As explained above, the present invention is easy to handle and
By providing a versatile corner protection piece that does not require auxiliary locking means such as adhesive tape, it can contribute to streamlining packaging and packing operations and improving safety.
