Mask attachment structure with two straps, top and bottom

Abstract

To provide a mask wearing structure with two upper and lower straps that is hard to slip off and can provide stable wearing. [Solution] The mask body is equipped with two straps, an upper strap and a lower strap, both of which are formed as circular bands that cross over in front of the user's ears and wrap around the back of the head. This provides stable support for the mask at two points, top and bottom, and suppresses swaying in the front-to-back and left-to-right directions. Stable retention is possible regardless of the presence or absence of components on the front side, maintaining comfort even when worn for long periods of time. Conventional mask wearing structures, often featuring ear hooks on both sides or a single band, have the problem of slippage in the front-to-back and up-to-down directions. Furthermore, when components such as a blower or sensor unit are attached to the front of the mask, their weight can easily cause the mask to tilt forward and downward, making stable wearing difficult. Even with conventional masks, sufficient retention strength is sometimes lacking, resulting in a lack of comfort when worn for long periods of time.

Description

[Technical Field]

[0001] This invention relates to a strap structure for securely attaching the mask body to the user's head, and is a fitting technology applicable to various masks, including those for medical, sleep, dust protection, disaster prevention, and sports. [Background technology]

[0002] Conventional mask wearing structures typically involve either left and right bands that hang over the ears or a single band that extends toward the top of the head. However, these structures tend to slip back and forth or up and down, making them unstable when worn for long periods of time. Furthermore, when components such as a blower or sensor are mounted on the front of the mask, their weight can easily cause the mask to slip forward and downward. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional mask wearing structures tend to slip forward and backward or up and down, making them unstable when worn for long periods of time. Furthermore, when components are mounted on the front of the mask, the weight of the components can cause the mask to slip forward and downward. The purpose of this device is to prevent these slippages by using two upper and lower straps and a cross structure in front of the ears, thereby achieving a stable fit regardless of whether or not the front components are present. [Means for solving the problem]

[0004] The mask wearing structure of this device has two straps, an upper strap and a lower strap, attached to the mask body. The upper strap passes over the upper side of the mask body and wraps around the back of the head, while the lower strap passes under the mask body and wraps around the back of the head, forming two support points, one above the other. These straps may be configured as a continuous circular band, or their ends may be connected to form a circular band with Velcro, buckles, snaps, sewing, etc. Furthermore, the upper and lower straps are positioned to cross each other in front of the user's ears, thereby suppressing rocking in the front-to-back, up-down, and left-to-right directions and ensuring a stable fit. [Effects of the Invention]

[0005] According to this device, the two-point support structure with two upper and lower straps and the crossing structure of the straps in front of the ears prevent the mask body from shifting in the front-to-back, up-down, and left-to-right directions, ensuring a stable fit. Even if components such as a blower or sensor are installed on the front side of the mask, the weight of these components is not easily affected, and the mask can be maintained in a stable position regardless of whether or not the front side components are installed. Furthermore, the straps wrap around the back of the head to distribute the force, improving comfort even when worn for long periods of time. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0007] In one embodiment of the present invention, two straps, an upper strap and a lower strap, are attached to the mask body. The upper strap passes over the upper side of the mask body and wraps around the back of the head, while the lower strap passes over the lower side of the mask body and wraps around the back of the head. These straps may be formed as a continuous, circular band, or their ends may be connected together by hook-and-loop fasteners, buckles, snaps, sewing, or other fasteners. The upper and lower straps are positioned to cross each other in front of the user's ears when worn. This crossing structure allows the straps to act as fulcrums, preventing the mask body from swinging left and right. Combined with the upper and lower support structures, this prevents the mask from shifting forward and backward and up and down. The upper and lower straps form a loop at the back of the head, so the force of the straps is absorbed by the entire head, reducing localized pressure and maintaining comfort even when worn for long periods of time.The structure of this device is less affected by the weight of components such as a blower or sensor module on the front of the mask, and allows for stable wearing. Furthermore, the structure of the present invention can be applied to a variety of masks, including those for medical, dustproof, sleep, disaster prevention, and sports, regardless of whether they have a front component or not. [Example]

[0008] This section describes an embodiment of a mask wearing mechanism that incorporates the strap structure of the present invention. In this embodiment, the two upper and lower straps of the present invention ensure stable wearing and holding in both cases, regardless of whether the mask has a front component such as a blower or no component on the front side of the mask body. In this embodiment, the mask body is equipped with two straps, an upper strap and a lower strap. The upper strap passes above the mask body and wraps around the back of the head, while the lower strap passes below the mask body and wraps around the back of the head. These straps are configured as annular ring-shaped bands, and when worn on the user's head, they are formed to cross each other in front of the ears, maintaining a gap between them in the vertical direction. This crossing structure makes it difficult for the mask body to move left and right, up and down, or front and back, improving wearing stability. The upper and lower straps also form occipital loops at the back of the head, distributing and supporting the tension from the straps across the entire head. This reduces localized pressure and stress, maintaining comfort even when worn for long periods of time. In particular, when the mask is equipped with front components such as a ventilation system, lighting system, camera, and sensor module on the front side of the mask, the weight of these components tends to concentrate forward. However, the upper and lower two-point support structure of this embodiment stabilizes the weight balance and effectively prevents the mask body from slipping forward and downward. Furthermore, the strap structure of this embodiment is not limited to any particular material or manufacturing method, and the strap may be configured as a one-piece circular band, or the ends may be connected to form a circular shape with hook-and-loop fasteners, buckles, snaps, etc. This allows for flexible configuration changes depending on the intended use and the wearer's head shape, making it applicable to a variety of mask devices, including those for medical use, disaster prevention, dust protection, sports, and comfortable sleep. The wearing structure of this embodiment provides a strong holding force on the user's head regardless of whether or not the front element is included, and in particular, the unique arrangement in which the upper and lower straps cross over in front of the ears suppresses swinging from multiple directions and securely holds the mask body in place. As described above, this embodiment can effectively achieve the effects of the present invention. [Industrial Applicability]

[0009] The mask attachment structure of this invention can be applied to a variety of mask products, including medical masks, sleep masks, dust masks, disaster prevention masks, and sports masks, regardless of whether they have a front-facing component. The attachment structure, which uses two upper and lower straps, prevents slippage in the front-to-back, up-down, and left-to-right directions, ensuring stable attachment. This makes it useful in a wide range of industrial fields, including general households, medical settings, nursing care, construction sites, outdoor activities, and sleep and health-related products. Furthermore, because the strap material and manufacturing method are not limited, it is easy to mass-produce and can be easily incorporated into existing mask manufacturing processes. Therefore, this invention has high industrial applicability.
