Description

[Detailed description of the invention] Industrial application field This invention can be applied to the corners of desks or pillars where infants may bump into them, or when transporting, packaging, storing, etc. equipment that is sensitive to shocks and vibrations. This relates to corner pads filled with a gel-like material that buffers and dampens vibrations.

Conventional technology Infants and toddlers who are just beginning to crawl or walk are still uncertain about their movements, and may suddenly fall over with a bang. On the other hand, there are many dangerous corners in the room, such as the corners of desks and pillars, and the mother has no time to take her eyes off her.

In the past, there were no versatile pads that could be easily applied to any corner, so even if each household devised appropriate methods such as applying cloth, it was extremely difficult to do so. It was common for things to be left as they were unless there was a danger.

In addition, styrofoam molded to the size of the corners is used for transport packaging for equipment that is sensitive to shock and vibration.

In addition, these devices may be housed in a protective outer case, or
During installation, anti-vibration rubber and insulators are used to prevent shock and vibration from being transmitted.

Problems that the invention aims to solve Conventionally, pads that can be applied to corners have been easily molded on the spot to fit each corner, whether for home use, business use, or other purposes.
There has never been anything that can be pasted on, is convenient for storage when not in use, and has excellent cushioning and anti-vibration properties.

Means for Solving the Problems The present invention has at least three gel-filled cells arranged adjacent to each other by at least two orthogonal adjacent compartments, each gel-filled cell having a circumference of each other on the front and back skins. They are joined and separated by compartment stripes so as to be independent of each other, and a gel-like substance is housed inside, and at least one side of the compartment strips is connected to an adjacent compartment strip with an adjacent gel-filled cell. It is characterized by having an adhesive layer polymerized on one of the front and back outer skins of the gel-filled cell.

Function The gel-filled corner pad of the present invention has gel-like substances housed in gel-filled cells whose peripheries are joined to each other on the front and back outer skins so that they are independent of each other, and which are divided into two orthogonal cells. Since it has at least three gel-filled cells arranged adjacent to each other by adjacent dividing lines, if the gel-filled cells are bent so that the lines of the gel-filled cells are perpendicular to each other at the adjacent dividing lines,
A three-dimensional pad is created that can cover the corner of three orthogonal planes, and is attached to the corner using an inner adhesive layer.

Additionally, if four or more gel-filled cells are arranged side by side, you can freely assign them accordingly, and three or more gel-filled cells can be partially cut out from a large number of gel-filled cells arranged side by side. .

Furthermore, once they are finished with their use, they are in sheet form, so they can be put together in any way they like, such as in a roll, and do not add bulk. Of course, since the gel-filled cells are filled with a gel-like substance, the buffering and vibration-proofing properties of the gel-like substance are also exhibited on the pads attached to the corners.

Embodiment The one shown in FIGS. 1 to 3 is an embodiment of the gel-filled corner pad of the present invention, which consists of the minimum number of three gel-filled cells. In this example, the gel-filled cells are: The synthetic resin film surface is filled with a gel-like substance so that it bulges out.

Reference numeral 10 denotes a dividing line formed by melting and joining the synthetic resin films 1 on the front and back sides, and this dividing line 10 is continuous so as to partition each block on the synthetic resin film, and one side thereof serves as a boundary. , the gel-filled cells 20 within this compartment are arranged adjacent to each other with one of them at the center. In the figure, division muscle 1
11 indicates the adjacent dividing line which is the boundary between 0 and 0. The gel-filled cell 20 is divided by dividing lines 10, and the synthetic resin film 1 within the compartment is bulged and filled with a gel-like substance.

On one side of the synthetic resin film 1, which is the outer skin, an adhesive layer 30, such as a cellophane tape or the like, is wound on at least the surface of the gel-filled cell 20 portion.

Therefore, in order to apply this to the corner of an object, align the two orthogonal adjacent partition lines 11 of this corner pad along the edge of the corner, apply the center gel-filled cell 20 to the corner surface, and then By bending it into a strip 11 and applying another gel-filled cell 20 to the other face of the corner, one corner, especially the apex angle formed by the intersection of three faces in this case, can be formed as shown in Fig. 1. Can be covered.

Also, if you use a device in which three or more gel-filled cells are connected as shown in FIG.
You can also cover the front corners lengthwise. Furthermore, this can be done in the same way by cutting out the large gel-filled corner pad shown in Figure 5 as shown by the dashed line B, or by cutting it out along the chain double dotted line C in the same figure. It is also possible to cover only the part indicated by the chain line A. In this case, the cut can be made only at the adjacent dividing line 11, and since the dividing line is thin, it can be easily cut by hand as well as with scissors.

Therefore, you can freely adjust it to that corner on the spot. However, when not in use, this corner pad is not three-dimensional but sheet-like, so it is not bulky and is convenient for storage.

It is easy to understand that the above embodiments are excellent for preventing danger to infants and young children in the home, but this is not suitable for conventional molded styrofoam or other materials used in transportation packaging for equipment that is sensitive to shocks and vibrations. It is easy to infer that it can be used as a substitute for vibration-proof rubber or insulators that were conventionally used when storing and arranging equipment in a protective outer case.
be understood.

Next, a method for manufacturing the gel-filled corner pad of the above embodiment will be described as an example.

To do this, it is first necessary to obtain a gel-like substance in the form of a thin plate of several millimeters to ten millimeters. To do this, the gel raw materials are kneaded and defoamed by hand, poured onto a glass plate, etc., and spread into a uniform layer with a spatula, or covered with upper and lower films and rolled with rolls, and then heated in a heating furnace. Appropriate measures such as gelation are taken. In addition, as a gel-like substance, JIS K 2530-1976-
Silicone gel with a penetration of about 50 to 200 measured by (50g load) and composite silicone gel made by mixing microscopic hollow spheres are the most suitable because they have excellent buffering and vibration-proofing abilities. Examples of such raw materials include Toray Silicone CF5027 (trade name) manufactured by Toray Silicone Co., Ltd., Filite (registered trademark) manufactured by Nippon Filite Co., Ltd., Expancel (registered trademark) sold by Nippon Filite Co., Ltd., and the like.

Next, a synthetic resin film such as vinyl chloride film, which has good heat weldability, or urethane film, which has inferior heat weldability but does not change much over time, is attached to the obtained thin plate-like gel material. , synthetic resin film, gel-like substance,
It is made of three layers of synthetic resin film.

Incidentally, if the synthetic resin film has weak heat weldability, a so-called hot melt may be superimposed on the synthetic resin film. In addition, in some cases,
Plates of highly thermoplastic polymer foam may be stacked on top of each other.

Thereafter, this layered sheet is pressed with a mold, and at the same time heat is applied to the synthetic resin film from the welding surface of the mold.This method includes high-frequency welding,
Heat press welding, ultrasonic welding, and the like are simple methods.

In addition, the mold in this case is one in which partitioned welding surfaces and adjacent recesses are formed alternately, and a partitioned welding surface is a continuous welding surface surrounding one recessed part, for example, a pattern with a base grain shape. The welding surface, ie, the recessed part, may be a type in which rectangular holes with rounded corners are arranged in an array, or not only in such a rectangular shape, but also in a shape in which triangular or other irregular shapes are arranged in an array. and,
The depth of the hole serving as the recess is preferably made sufficiently deep to provide a space in which the synthetic resin film can be deformed so as not to hinder the formation of the gel-filled cell.
The one shown in FIG. 6 was manufactured from a mold with triangular holes.

At the time of welding, this mold is applied to the synthetic resin film. At this time, if this mold is used on both sides, the welding streaks, which are the partitioning streaks 10, will overlap the gel-filled cells 20 as shown in FIG. If this mold is used only on one side and a flat mold is used on the other side, the weld line will be biased to one side. In this case, the former method is disadvantageous in terms of adhesion to the corner surface, but the corner can be reliably covered. Moreover, according to the latter, although it is disadvantageous in terms of ensuring that the apex of the corner is covered, it is advantageous in terms of adhesion.

However, regardless of the type, after the synthetic resin film is welded, weld lines serving as partition lines are formed. The gel-like substance where this welding streak is formed is divided by the partitioned welding surface of the mold, so
Escapes to adjacent recesses on the front, back, left and right. Since there is a gel-like material that was originally located in the adjacent recess, the gel-like material that escapes from front to back, left and right pushes in the gel-like material that was originally located, and becomes thicker than when it was in the original thin plate shape.
It partially folds in on itself and escapes into the adjacent recess.

On the other hand, the front and back sides of the synthetic resin film on the partitioned welding surface overlap, receive heat locally in a timely manner from an appropriate type of heating means, and are welded on the front and back sides, forming a single leaf-shaped weld line.

At this time, the synthetic resin film corresponding to the adjacent concave portion is stretched by the gel-like substance escaping from the front, back, left, and right sides, and encapsulates the gel-like substance, so that the surface of the synthetic resin film
In particular, the unrestricted side bulges out into a substantially spherical shape, resulting in the formation of a gel-filled cell containing a gel-like substance.

In this way, a plurality of gel-filled cells are formed corresponding to the recesses of the mold.

Then, an adhesive layer is polymerized on one side of the synthetic resin film that is the outer skin of this gel-filled cell. If a gel-filled cell is formed using a synthetic resin film originally coated with an adhesive, the adhesive layer may be polymerized therefrom. Note that it is desirable that a release paper be applied to the adhesive layer.

Further, for example, if each side of the grid-like section welding surface is about 10-odd millimeters, it is optimal for keeping it at home, but it is not limited to this size for commercial use. In addition, transportation packaging,
If a thick one is required for use in storage, etc., a thermoplastic synthetic resin film is first formed into a deep case shape by vacuum forming, and a block of gel-like substance is inserted into this. Thick gel-filled corner pads can be made relatively easily by inserting a gel-filled corner pad, covering it with another synthetic resin film, and welding the edges.

Of course, the gel-filled corner pad of the present invention is not limited to the above-mentioned methods, and may be manufactured by bonding with adhesive or by any suitable method. It's not limited either.

Effects of the invention As stated above, according to the invention, the cushioning and vibration-proofing properties of the material itself are excellent, so it goes without saying that even if an infant, etc. hits a corner, the impact is absorbed by the gel-like material. It absorbs quickly, so cuts and bruises are less likely to occur.

In addition, by bending the gel-filled cells so that the faces of each gel-filled cell are perpendicular to each other at the adjacent partition lines, it is possible to create a three-dimensional pad that can cover corners made of three orthogonal faces or two orthogonal faces. If four or more gel-filled cells are arranged side by side, you can cut them out and place them in any way you like.Furthermore, when you are done using them, you can freely roll them up and store them without adding bulk. It's convenient.
