Description

This device is an auxiliary tool for improving the usability of various daily necessities used in daily life, and more specifically, it applies to the body parts that these come into contact with when using earplugs of hygiene masks or modern glasses. The present invention relates to a member that reduces such contact pressure.

For example, when wearing a hygiene mask on the back outer periphery of the ear with the ear straps hung, when wearing glasses, on the upper back outer periphery of the ear with the modern hang, when hanging the handbag It is well known that the contact pressure is applied to the palm of the hand or the pad of the finger that holds the carrying strap.

For items such as sanitary masks and glasses that are attached to the body for use, in order to ensure the attachment, some contact pressure is not applied to the contact part of the body, and the items are stored in the carrying bag. It is unavoidable that a certain amount of contact pressure will be generated depending on the weight of the article, but if excessive contact pressure continues for a long time, it will cause a feeling of wear to deteriorate and cause pain to the body part in contact with them. Therefore, some measure to reduce this excessive contact pressure was necessary.
However, it is difficult to find an auxiliary tool that can effectively reduce excessive contact pressure at low cost.

The present inventor has conducted diligent research as a solution to this problem concerning contact pressure applied to body parts when using various daily necessities such as sanitary masks and glasses, and as a result, it is possible to produce at low cost and effectively reduce contact pressure. We have succeeded in developing a simple and convenient contact pressure reducing tool, and propose it here as the present invention.

A contact pressure reducing device in which a spiral cut that penetrates the front and back is formed from the upper end to the lower end of the peripheral wall of a cylindrical main body made of a soft resin having elasticity, and is wound around the peripheral wall surface of an object. The above-mentioned problem was solved by.

It is used by winding it around the peripheral wall of a string-shaped or columnar object, and when the object is a hygiene mask ear-hook string, the object is modern glasses, or the object is a handbag bag. In the case of a string, the string is wrapped around the object and used. By doing so, this contact pressure reducer will be interposed between the object and the body part such as the ear or hand where the load is applied, so that the contact surface is widened and the contact pressure is greatly increased due to its elasticity. Even if you wear or hang it for a long time, the contact surface will not have any pain or discomfort.

Moreover, the structure is extremely simple, it can be easily manufactured at low cost, and not only can it be easily retrofitted to the earplug strings of hygiene masks, modern glasses, handbags, etc., but it can also be easily removed. It can also be used for multiple objects and has excellent practical value.

In addition, since a spiral cut is formed on the peripheral wall of the main body, it can be easily attached and detached by expanding this cut, and there is no danger of accidentally detaching from the object during mounting, Have credibility.

The enlarged perspective view of one Example of the contact-pressure reduction tool which concerns on this invention. The perspective view of the state which attached the contact-pressure reducing tool which concerns on this invention to the ear hook string of a sanitary mask. The perspective view of the state which attached the contact-pressure reducing tool which concerns on this invention to the modern of glasses. FIG. 3 is a perspective view showing a state in which the contact pressure reducing device according to the present invention is attached to a hand strap of a handbag.

The greatest feature resides in that a spiral cut that penetrates the front and back is formed from the upper end to the lower end of the peripheral wall of the main body of the contact pressure reducing device made of elastic soft resin.

FIG. 1 is a perspective view of an embodiment of the contact pressure reducing device according to the present invention. In the figure, reference numeral 1 denotes a cylindrical main body made of elastic soft resin, and a peripheral wall 2 has a spiral cut 3 extending from the upper end to the lower end of the peripheral wall 2. The material of the main body 1 may be either synthetic material or natural material as long as it is a soft resin having elasticity, but silicone rubber or rubber-based material can be preferably used.

The pitch of the spiral cut 3 may be uniform or non-uniform, but as shown in FIG. 1, the pitch angle Θ ₁ of the cut 3 near the upper end and the lower end is set to be smaller than the pitch angle Θ ₂ of the middle portion. , Θ ₁ <Θ ₂ , and in such a case, the attachment to the object becomes more reliable and the detachment is less likely to occur.

The spiral cut 3 can be easily formed by cutting the peripheral wall 2 of the cylindrical main body 1 with a blade of a cutter, and no special tool or dedicated equipment is required for the formation.

In this embodiment, the object is wound around a string-shaped or columnar object and is used. When the object is the ear hook string 5 of the hygiene mask 4, the ear hook string 5 is used as shown in FIG. Wrap and use. By doing so, when the sanitary mask 4 is worn, the ear straps 5 do not come into direct contact with the rear outer periphery of the wearer's ears, and this contact pressure reducing device is interposed, so that the contact surface is widened. Due to the elasticity of the main body 1, the contact pressure applied to the rear outer periphery of the ear is significantly reduced. Therefore, even if the hygiene mask 4 is worn for a long time, the back outer circumference of the wearer's ear does not cause pain or discomfort.

On the other hand, in the case where the object is the modern 7 of the glasses 9, the object 7 is wrapped around the outer periphery of the modern 7 for use as shown in FIG.
By doing so, when the glasses 9 are worn, the modern 7 does not directly contact the upper, rear, and outer peripheries of the wearer's ears, and this contact pressure reducing tool is interposed, so that the contact surface is widened and the main body 1 Due to the elasticity of, the contact pressure exerted on the upper and rear outer circumference of the ear is significantly reduced. Therefore, even if the glasses 9 are worn for a long time, no pain or discomfort is caused in the rear outer circumference of the ear of the wearer with which the modern 7 is in contact.

Further, when the object is the handbag 8 of the handbag 10, it is wrapped around the outer periphery of the handbag 8 for use as shown in FIG.
By doing so, when the handbag 10 is hung by hand, the handheld cord 8 does not directly contact the palm or the belly of the finger, and this contact pressure reducing tool is interposed, so that the contact surface is widened and the main body 1 Due to the elasticity of, the contact pressure exerted on the palm and the pad of the finger is significantly reduced. Therefore, even if the heavy handbag 10 is hung for a long time, the palm or the belly of the finger does not cause pain or discomfort.

The contact pressure reducing device according to the present invention has the above-mentioned configuration, has a simple structure, can be easily manufactured at low cost, and can be used as ear straps for sanitary masks, modern glasses, and hand straps for carrying bags. Not only can it be easily retrofitted, it can also be easily removed, and it can be reused for multiple objects and has excellent practicality.

In addition, since a spiral cut is formed on the peripheral wall of the main body, by expanding this cut, it can be easily attached and detached, and there is no risk of accidentally detaching from the object during mounting, Has high reliability.
In particular, as shown in FIG. 1, in the case where the pitch of the breaks near the upper end and the lower end of the main body is set smaller than that of the central part, it is hard to come off and has higher reliability.

It can be widely applied not only to hygiene masks, glasses or handbags, but also to everyday items worn on the body or hanging.
