Description

FIELD OF THE DISCLOSURE

The present disclosure relates to a mask, and more particularly to an assembled full-face mask.

BACKGROUND OF THE DISCLOSURE

A conventional full-face mask for covering the entire face of a user is integrally formed as a single one-piece structure, which results in a lot of inconvenience for the user. For example, when the user needs to talk on the phone, the conventional full-face mask has to be completely removed.

SUMMARY OF THE DISCLOSURE

In response to the above-referenced technical inadequacy, the present disclosure provides an assembled full-face mask to effectively improve on the issues associated with conventional full-face masks.

In one aspect, the present disclosure provides an assembled full-face mask, which includes a goggle, an outer lens, and a mask shell. The goggle includes a lens frame, a pivotal seat, and a lens. The lens frame is in an annular shape and has a top portion, two lateral portions, a bottom portion, and two pivotal portions that are respectively formed on the two lateral portions. The pivotal seat is disposed on the top portion. The lens is assembled to the lens frame and is arranged in a space that is surroundingly defined by the top portion, the two lateral portions, and the bottom portion. The outer lens includes a sheet and a pivotal frame that is connected to the sheet. The pivotal frame is assembled to the pivotal seat, the sheet covers the lens, and the outer lens is rotatable relative to the goggle along a first axis. The mask shell includes two connection rods and a shell body. The two connection rods are respectively assembled to the two pivotal portions. The shell body is connected to the two connection rods. The mask shell is rotatable relative to the goggle along a second axis that is parallel to and spaced apart from the first axis. When one of the outer lens and the mask shell is rotated relative to the goggle by a first angle, another one of the outer lens and the mask shell is rotatable relative to the goggle by a second angle that is less than the first angle.

In another aspect, the present disclosure provides an assembled full-face mask, which includes a goggle, an outer lens, and a mask shell. The outer lens includes a sheet and a pivotal frame that is connected to the sheet. The pivotal frame is assembled to the goggle, and the outer lens is rotatable relative to the goggle along a first axis. The mask shell includes two connection rods and a shell body. The two connection rods are assembled to the goggle. The shell body is connected to the two connection rods. The mask shell is rotatable relative to the goggle along a second axis that is parallel to and spaced apart from the first axis. When one of the outer lens and the mask shell is rotated relative to the goggle by a first angle, another one of the outer lens and the mask shell is rotatable relative to the goggle by a second angle that is less than the first angle.

Therefore, any one of the outer lens and the mask shell of the assembled full-face mask in the present disclosure can be independently rotatable relative to the goggle by the structural design of the goggle in cooperation with the outer lens and the mask shell, thereby providing convenience in use of the assembled full-face mask.

These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

Referring to FIG. 1 to FIG. 11, an embodiment of the present disclosure provides an assembled full-face mask 100 for substantially covering the entire face of a user. As shown in FIG. 1 to FIG. 3, the assembled full-face mask 100 includes a goggle 1, an outer lens 2 pivotally connected to the goggle 1 along a first axis C1, and a mask shell 3 that is pivotally connected to the goggle 1 along a second axis C2. The first axis C1 is parallel to and spaced apart from the second axis C2, and any one of the outer lens 2 and the mask shell 3 is independently rotatable relative to the goggle 1, thereby providing convenience of using the assembled full-face mask 100.

Moreover, in order to clearly describe the structure of the assembled full-face mask 100, the assembled full-face mask 100 defines a bisecting plane P perpendicular to the first axis C1 and the second axis C2, and the bisecting plane P can be defined by a first direction D1 and a second direction D2 that is perpendicular to the first direction D1. The first direction D1 in the present embodiment is parallel to a forward viewing direction of the goggle 1. In other words, the assembled full-face mask 100 in the present embodiment is a mirror-symmetrical structure with respect to the bisecting plane P.

As shown in FIG. 3 to FIG. 5, the goggle 1 in the present embodiment includes a lens frame 11, a lens 12 fixed to the lens frame 11, and a pivotal seat 13 that is detachably assembled to the lens frame 11, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the goggle 1 can be other structures (e.g., the lens frame 11 and the pivotal seat 13 are integrally formed as a single one-piece structure); or, the goggle 1 can be formed by adding other components.

The lens frame 11 is in an annular shape and includes a top portion 111, two lateral portions 112, a bottom portion 113, two pivotal portions 114 respectively formed on the two lateral portions 112, and two positioning columns 115 that are respectively formed on the two lateral portions 112. The top portion 111 and the two lateral portions 112 are connected to each other so as to jointly form in a substantial U-shape, the bottom portion 113 is in a substantial W-shape, and two distal ends of the bottom portion 113 are respectively connected to the two lateral portions 112. Moreover, the lens 12 is assembled to the lens frame 11, and is arranged in a space that is surroundingly defined by the top portion 111, the two lateral portions 112, and the bottom portion 113.

Specifically, the two pivotal portions 114 are arranged adjacent to the top portion 111, and the two pivotal portions 114 can jointly define the second axis C2, but the present disclosure is not limited thereto. In other words, a distance D113 between the second axis C2 and the bottom portion 113 is at least four times of a distance D111 between the second axis C2 and the top portion 111 (as shown in FIG. 6). The two positioning columns 115 are respectively arranged adjacent to the two pivotal portions 114, and are respectively located under the two pivotal portions 114. In the present embodiment, any one of the two positioning columns 115 is in a cylindrical shape, and a height of any one of the two positioning columns 115 is slightly larger than a height of the pivotal portion 114 adjacent thereto. The two positioning columns 115 are arranged adjacent to the lens 12.

The pivotal seat 13 is disposed on the top portion 111 of the lens frame 11, and is preferably detachably assembled to (e.g., buckled with) a center region of the top portion 111. In the present embodiment, the pivotal seat 13 is integrally formed as a single one-piece structure, and includes a carrier 131 assembled to the top portion 111, two buckling portions 132 connected to the carrier 131, and two limiting cantilevers 133 that are connected to the carrier 131.

The pivotal seat 13 (or the two buckling portions 132) in the present embodiment can define the first axis C1, but the present disclosure is not limited thereto. The carrier 131 of the pivotal seat 13 has a hollow region 134 between the two buckling portions 132, and the two limiting cantilevers 133 are substantially arranged between the two buckling portions 132 and are arranged in the hollow region 134, so that any one of the two limiting cantilevers 133 in the hollow region 134 is elastically swingable toward the top portion 111.

Specifically, as shown in FIG. 6, on the bisecting plane P, the first axis C1 and the second axis C2 are spaced apart from each other along the first direction D1 by a longitudinal distance V. Moreover, a lens projection area defined by orthogonally projecting the lens 12 onto the bisecting plane P has a height H12 in the second direction D2, and the longitudinal distance V is 30% to 40% of the height H12.

As shown in FIG. 7, on the bisecting plane P, the first axis C1 and the second axis C2 are spaced apart from each other along the first direction D1 by a transverse distance H. Moreover, a frame projection area defined by orthogonally projecting the lens frame 11 onto the bisecting plane P has a width W11 in the second direction D2, and the transverse distance H is equal to or less than the width W11.

It should be noted that a quantity of the limiting cantilevers 133 of the pivotal seat 13 is two, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, a quantity of the limiting cantilever 133 of the pivotal seat 13 can be at least one.

As shown in FIG. 3 to FIG. 5, the outer lens 2 in the present embodiment is integrally formed as a single one-piece structure, and includes a sheet 21 and a pivotal frame 22 that is connected to a top edge of the sheet 21. The sheet 21 of the outer lens 2 in the present embodiment is a filter, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the sheet 21 can be a protective sheet having a hardness higher than that of the lens 12.

The pivotal frame 22 is assembled to the pivotal seat 13, so that the outer lens 2 is rotatable relative to the goggle 1 along the first axis C1, and the sheet 21 covers the lens 12. In the present embodiment, the shape of the sheet 21 is substantially identical to the shape of the lens 12, so that the sheet 21 can cover an entirety of the lens 12, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the sheet 21 can cover a portion of the lens 12.

Moreover, the pivotal frame 22 includes a rotation shaft 221 arranged along the first axis C1 and two connection bridges 222 that are connected to the rotation shaft 221 and the sheet 21. A central axis of the rotation shaft 221 is overlapped with the first axis C1. A shaft projection area (as shown in FIG. 7) defined by orthogonally projecting the rotation shaft 221 onto the top portion 111 is preferably located at the center region of the top portion 111. Any one of the two connection bridges 222 in the present embodiment is connected to an end of the rotation shaft 221 and a top edge of the sheet 21 by straddling the carrier 131.

Specifically, the rotation shaft 221 includes two circular segments 2211 and a non-circular segment 2212 that is arranged between the two circular segments 2211. In other words, two ends of any one of the two circular segments 2211 are respectively connected to one of the two connection bridges 222 and the non-circular segment 2212. In the present embodiment, the circular segment 2211 has a circular cross section perpendicular to the first axis C1, and the non-circular segment 2212 has a non-circular cross section (e.g., a polygonal cross section) perpendicular to the first axis C1.

The two circular segments 2211 are rotatably assembled to the pivotal seat 13, and the non-circular segment 2212 abuts against and is retained by the pivotal seat 13 so as to fix the outer lens 2 at different positions when the outer lens 2 is rotated relative to the goggle 1. In the present embodiment, the two circular segments 2211 are respectively buckled into the two buckling portions 132, and the non-circular segment 2212 abuts against and is retained by the two limiting cantilevers 133, so that the two limiting cantilevers 133 are configured to provide a reaction force to the non-circular segment 2212.

As shown in FIG. 3, FIG. 4, and FIG. 8, the mask shell 3 is integrally formed as a single one-piece structure, and includes two connection rods 31 and a shell body 32 that is connected to the two connection rods 31. The two connection rods 31 are respectively assembled to the two pivotal portions 114 (e.g., each of the two connection rods 31 is detachably assembled to the corresponding pivotal portion 114), so that the mask shell 3 is rotatable relative to the goggle 1 along the second axis C2. Specifically, a top edge of the shell body 32 and a bottom edge of the sheet 21 correspond in shape to each other and are spaced apart from each other so as to form an elongated gap G therebetween. Moreover, the top edge of the shell body 32 and the bottom edge of the sheet 21 can contact with an outer surface of the bottom portion 113 of the lens frame 11.

As shown in FIG. 9 and FIG. 10, when one of the outer lens 2 and the mask shell 3 is rotated relative to the goggle 1 by a first angle, another one of the outer lens 2 and the mask shell 3 is rotatable relative to the goggle 1 by a second angle that is less than the first angle. In the present embodiment, a difference between the first angle and the second angle is within a range from 15 degrees to 35 degrees.

For example, when the assembled full-face mask 100 has the difference of 35 degrees and the outer lens 2 is rotated relative to the goggle 1 at 90 degrees (i.e., the first angle), the mask shell 3 can be rotated relative to the goggle 1 by an angle (i.e., the second angle) less than 55 degrees.

In addition, as shown in FIG. 3, FIG. 4, and FIG. 11, the two positioning columns 115 of the assembled full-face mask 100 respectively abut against and are retained by the two connection rods 31 so as to fix the mask shell 3 at different positions when the mask shell 3 is rotated relative to the goggle 1.

Specifically, each of the two connection rods 31 has a plurality of engaging slots 311. Each of the engaging slots 311 is spaced apart from the second axis C2 by a same distance that is equal to a distance between the corresponding positioning column 115 and the second axis C2, so that any one of the two positioning columns 115 can be selectively engaged with one of the engaging slots 311 of the corresponding connection rod 31. In any one of the two connection rods 31 of the present embodiment, the engaging slots 311 jointly define a central angle by taking the second axis C2 as a center of circle, and the central angle is within a range from 45 degrees to 70 degrees.

Beneficial Effects of the Embodiment

In conclusion, any one of the outer lens and the mask shell of the assembled full-face mask in the present disclosure can be independently rotatable relative to the goggle by the structural design of the goggle in cooperation with the outer lens and the mask shell, thereby providing convenience of using the assembled full-face mask.

Moreover, the goggle of the assembled full-face mask of the present disclosure can be in cooperation with the outer lens by detailed structural design thereof (e.g., the non-circular segment abuts against and is retained by the pivotal seat so as to fix the outer lens at different positions when the outer lens is rotated relative to the goggle; or, the non-circular segment abuts against and is retained by the limiting cantilever, so that the limiting cantilever is configured to provide a reaction force to the non-circular segment), thereby further increasing the convenience of using the outer lens of the assembled full-face mask.

In addition, the goggle of the assembled full-face mask of the present disclosure can be in cooperation with the mask shell by detailed structural design thereof (e.g., the two positioning columns respectively abut against and are retained by the two connection rods so as to fix the mask shell at different positions when the mask shell is rotated relative to the goggle; or, any one of the two positioning columns is selectively engaged with one of the engaging slots of the corresponding connection rod), thereby further increasing the convenience of using the mask shell of the assembled full-face mask.
