Before the present invention is described in greater detail with reference to the accompanying preferred embodiments, it should be noted herein that like elements are denoted by the same reference
numerals throughout the disclosure.
Referring to Figs. 2 and 3, a respiratory mask 2 of the first preferred embodiment according to this invention includes a mask body 4, a front cover 32, a forehead support unit 3, a hinge unit 5, and an adjustment unit 6.
The mask body 4 includes a mask shell 41, a mask cushion 42 connected to a rear side of the mask shell 41 and adapted to contact a user' s nose and/or mouth, and an air conduit 43 projecting forwardly from the mask shell 41.
The front cover 32 is disposed in front of and is hinged to the mask shell 41, and has a support arm32Oextendingupwardly. The front cover 32 further has a mid hole 322 for extension of the air conduit 43 therethrough and two opposite sides respectively provided with a pair of strap connectors 323.
The forehead support unit 3 has a forehead frame 31 and a forehead pad 33 connected to a rear side of the forehead frame 31.The forehead frame 31 has a T-shaped frame part 311 connected to a top end of the support arm 320 and is provided with a pair of slotted connectors 312 on two opposite sides thereof.
The hinge unit 5 includes a hinge pin 51 mounted to a lower part of the front cover 32 in a transverse direction transverse to a front-to-rear direction of the mask shell 41, two hinge seats 52 projecting from a lower part of the mask shell 41, and two insert holes 53 respectively formed in the hinge seats 52 for insertion of the hinge pin 51 therethrough. By virtue of the hinge unit 5, an upper part of the mask shell 41 can be rotated toward and away from an upper part of the front cover 32 so that the mask body 4 can provide a gas tight seal and a comfortable abutment pressure against the user's nose.
The adjustment unit 6 is connected to and disposed on the front cover 32 and the mask shell 41 above the air conduit 43, and is operable to produce relative movements of the upper parts of the mask shell 41 and the front cover 32 so that relative positions of the mask shell 41 and the front cover 32 can be adjusted.
In this embodiment, the adjustment unit 6 includes a pair of adjustment members 61 which project forwardly from the mask shell 41 to extend through the mid hole 322 of the front cover 32, and which are formed as a pair of resilient members. Each of the adjustment members 61 has four adj usting elements that are formed as four locking holes 611 and that are spaced apart from each other in the front-to-rear direction.
Thefrontcover32furtherhastwotongues62protruding into the mid hole 322 and engageable with a selected one of the locking holes 611 in each of the adjustment members 61.
The adjustment members 61 are movable between a locking position and a non-locking position.
Referring to Fig. 4, at the locking position, one of the locking holes 611 in each of the adjustment members 61 engages one of the tongues 62, thereby locking the mask body 4 against movement. Referring to Fig. 5, at the non-locking position, the adjustment members 61 are pressed toward each other to disengage the tongues 62 from respective ones of the locking holes 611 such that the mask body 4 can be rotated about the hinge pin 51 relative to the front cover 32.
Referring to Fig. 6, in use, head straps 70 are inserted respectively through the slotted connectors 312 and the strap connectors 323 and then extend rearwardly around the user's head 80. Rfter adjusting a suitable pulling force to secure the respiratory mask 2 to the user's head 80, the mask body 4 is adjusted to pivot relative to the front cover 32 through the adjustment unit 6 such that an angle formed therebetween can he adjusted, thereby providing an abutment pressure against the root of the user's nose suitable for the facial dimensions of different users.
For example, referring to Fig.7, the user has a flat nose shape and a relatively high forehead.
Referring to Fig. 8, the user has a straight nose shape and a relatively low forehead. In both cases, the adjustment unit 6 is operated to move the upper part of the mask body 4 toward to the user's head 80, and the adjustment members 61 are locked by engaging the respective tongues 62 at the suitable locking holes 611 so that a suitable abutment pressure is provided against the root of the user's nose. It is noted that the locking holes 611 used in the case of Fig. 8 are nearer to the mask shell 41 compared to the locking holes 611 used in the case of Fig. 7.
It is worth mentioning that the relative positions of the mask shell 41 and the front cover 32 are varied depending on the actual requirements.
Referring to Figs. 9 and 10, the second preferred embodiment of the present invention differs from the first preferred embodiment in that the adjustment member 61 is formed as a single strip member that includes five locking grooves 611' acting as the adjusting elements. The front cover 32 further has an edge part 66 that bounds partially an upper part of the mid hole 322 and that selectively engages one of the locking grooves 611'. The adjustment member 61 is resilient to move downwardly when a force is applied thereon such that the edge part 66is disengaged from the locking grooves 611' to allow the relative movements of the upper parts of the mask shell 41 and the front cover 32. Subsequently, when the mask shell 41 is adjusted to a desired position, the force is released and the adjustment member 61 moves upwardly to engage the edge part 66 in another of the locking grooves 611', therebyonceagainlockingthemaskshell 41 and the front cover 32 against movement.
Referring to Figs. 11 and 12, the third preferred embodiment of the present invention differs from the firstpreferredembodiment inthattheadjustmentunit 6 includes a screw hole 63 provided in the upper part of the front cover 32, a connection member 64 connected toandextendingforwardlyfromthemaskshell4lbehind the front cover 32, and a driving screw 65 engaged threadedly to the screw hole 63. The connectionmember 64 is resilient and has a through hole 641 corresponding in position to the screw hole 63. The driving screw 65 has a screw portion 651, a drive portion 652 extending rearwardly from the driving screw 654 and having a cross-section larger than that of the through hole 641 of the connection member 64, and a middle portion 653 extending between the screw portion 651 and the drive portion 652. The screw portion 651 is engaged threadedly to the screw hole 63, and the middle portion 653 extends through the through hole 641. When the screw portion 651 is rotated in one direction, the drive portion 652 abuts against and pulls the connection member 64 to move forwardly, thereby driving the mask shell 41 to move. Conversely, when the screw portion 651 is rotated in an opposite direction, thedriveportion 652 allows themasksheil 41 to move rearwardly.
ReferringtoFigs. l3andl4, the fourthpreferred embodiment of the present invention differs from the second preferred embodiment in that the front cover 32 has a substantially U-shape. The hinge unit 5 includes two hinge pins 51' extending oppositely from two opposite sides of the mask shell 41 and transverse to the front-to-rear direction, and two insert holes 53 formed respectively in two opposite sides of the front cover 32. The hinge pins 51' extend through the insert holes 53, respectively.
It is worth mentioning that the adjustment unit 6 embodied in the first and third embodiments can also be applied in this embodiment.
By virtue of the hinge unit 5 and the adjustment unit 6, the angle of the mask shell 41 relative to the front cover 32 can be altered so as to provide a comfortable abutment pressure against the root of the user's nose to suit the facial dimensions of different users.
