Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since rigid plastic has a fixed shape, it does not conform to individual nose shapes, which is inconvenient. In addition, it cannot be worn on masks of various shapes, lacking convenience. Moreover, when wearing a mask, rigid plastic has visual problems such as bulging parts and being conspicuous.

[0005] Furthermore, using double-sided tape to prevent masks from slipping resulted in a decrease in adhesive strength over time. Also, since the tape had to be discarded with each mask change, it was economically disadvantageous. In addition, the adhesive part posed a risk of bacteria and pollen adhering to it, raising hygiene concerns.

[0006] Furthermore, in masks that use a nose wire to prevent glasses from fogging up, a long, narrow piece of material is used that includes the nose and cheeks. However, when the cheeks protrude, for example, due to laughter, the material lifts up from the nose, reducing its fixing strength and widening the gap between the mask and the cheeks, causing glasses to fog up. Moreover, although the long, narrow piece of material has a certain degree of strength, it still flattens over time, making it functionally insufficient. [Means for solving the problem]

[0007] The slip prevention device of this invention solves the respective problems by having a single-unit structure consisting of a plastically deformable metal plate made of thin metal and attachments provided at both ends of one side of the metal plate.

[0008] The metal plate is bendable with the fingertips, but it is made of a metal strong enough that it does not easily recover its shape from the tension applied to the ears by the mask, thus maintaining its shape for a long period of time. Initially, the metal plate is flat, but when attached to the mask, it is adjusted to fit the individual nose shape and bent into a roughly V-shape. When this is placed against the bridge of the nose and the mask is put on, the pressure of the mask is added, and both sides of the metal plate press against the sides of the nose, fixing it in place. As a result, it adheres firmly to the sides of the nose along with the mask, and because it is fixed by pressing only against the nose, it is not affected by the protrusion of the cheeks.

[0009] The mounting device consists of male and female components that interlock to connect with the mask, and the mounting device can be attached by clamping it from both sides of the mask, which is a major feature of the anti-slip device of this invention. [Effects of the Invention]

[0010] The attachment mechanism is snap-on, allowing it to be easily attached to and detached from any shape of mask, and it is reusable. Furthermore, it avoids the risk of bacteria and pollen adhering to the mask, resulting in improved convenience and significant economic and hygienic benefits.

[0011] Furthermore, plastic products have a fixed shape from the outset, making them inconvenient to purchase as they do not accommodate individual sizes. This invention solves this problem because the anti-slip device can be freely adjusted to fit the shape of the nose. Also, because the anti-slip device is made thin, it does not bulge out and stand out compared to thicker plastic devices. In addition, even if the metal plate is made larger to achieve high grip strength, it does not appear visible from the surface of the mask because it conforms to the shape of the nose, which is an advantage.

[0012] Furthermore, the anti-slip device of this invention attaches to the mask and firmly presses against the sides of the nose, thus minimizing the gap that occurs at the upper edge of the mask and preventing glasses from fogging up due to air leakage. In addition, the anti-slip device firmly holds the mask in place against the pulling force from the chin acting on the mask, maintaining stable slip prevention.

[0013] The anti-slip device of this invention pursues a thin and compact design, so that it does not take up much space even when placed in a small item case, and it can be returned to its flat state even after being bent, making it convenient to carry around and thus contributing to improved usability.

(B) is a perspective view of the anti-slip device according to this embodiment in a state where it is bent into a roughly V shape. [Figure 2] This is a side view showing the anti-slip device according to this embodiment attached to a mask and worn on the face. [Figure 3] This is a right side view of the mounting fixture according to this embodiment. [Figure 4]This is a view from below of the misalignment preventer according to this embodiment attached to a mask.

Embodiment for Carrying Out the Invention

[0015] The misalignment preventer 1 of the present invention is realized as a single body structure including a thin metal sheet 2 that plastically deforms and a fixture 3 attached to one surface.

Example

[0016] The metal sheet 2 of this embodiment shown in Fig. 1(A) is formed into a substantially rectangular shape using a thin metal sheet that plastically deforms and is an aluminum sheet with a thickness of 0.3 mm. However, the condition is that the thickness has the minimum strength that does not allow the shape to recover against the tension acting on the mask, and even considering the balance between the material and strength, it is desirable to be formed within the range of 0.2 mm to 0.5 mm. Incidentally, the material is a metal having plasticity.

[0017] The misalignment preventer 1 of the present invention shown in Fig. 1(B) is in a state bent from a flat state (A) to a substantially V shape (B). However, since it is a thin metal sheet, it is easy to bend and can be freely adjusted to individual nose shapes.

[0018] The broken line surrounding the nose shown in Fig. 2 indicates the general range B beside the nose. The misalignment preventer is formed to fit within the range from the root of the nose A1 to the tip of the nose A2 and the range B beside the nose. Therefore, the metal sheet 2 may be, for example, substantially square or substantially elliptical within the above range, and there is no particular limitation on the shape and size. However, it is desirable to be formed by dividing into large, medium, and small sizes and having the average value at each stage.

[0019] Figure 3 is a right side view of the fixture 3. The fixture of the present invention is configured such that a male member 3a and a female member 3b are fitted and joined as a set, and male members are adhesively fixed to both ends of the metal plate 2 (shown in Fig. 1(A)). When attaching to the mask M, the male member is applied to the position corresponding to the bridge of the nose on the back surface of the mask, and by sandwiching the mask and fitting the female member with the male member, it is configured to be attached to the mask.

[0020] In this embodiment, the fixture 3 utilizes a general snap button. Of course, it is not limited to snap buttons, and there is no particular limitation as long as it has a function capable of fitting and joining, and the same applies to the shape and size.

[0021] The fixture 3 of this embodiment is made of plastic, but it may also be made of other materials such as metal or synthetic resin, and there is no particular limitation on the material.

[0022] Figure 4 is a view of the mask M with the displacement prevention device 1 attached as seen from below. As shown in this figure, the displacement prevention device is placed on the nose like a horse's saddle and locked, and the pressure of the mask is also applied. As a single unit, it presses and fixes only the nose, so it is not affected by the swelling of the cheeks and firmly presses down to the lower part of the side of the nose. As a result, the gap C at the upper edge of the mask is blocked as much as possible, and air leakage is suppressed.

[0023] In addition, a sheet may be provided in the area of the surface of the metal plate 2 that contacts the face, or on both surfaces. It is desirable for achieving a buffering effect and a gripping effect. Also, it is desirable that the material of the sheet is formed of a rubber material and / or a synthetic resin material and / or a soft material and / or a soft synthetic resin material.

[0024] The displacement prevention device 1 of the present invention indicates a state where the metal plate 2 and the fixture 3 are integrated. The same applies when adding the sheet described above.

Industrial Applicability

[0025] The anti-slip device of this invention is compact, highly convenient, economically and hygienically useful, and can be produced at low cost, so it is expected to become widely adopted. [Explanation of Symbols]
