Description

OPENING AND CLOSING DEVICE OF FULL FACE MASK FOR DIVING}

The present invention relates to a closed closed device for a full face mask for diving, and relates to a closed closed device for a full face mask for diving to open and close the nostril of the wearer while the rod-type closed closed device is elevated by the pressure of the wearer.

In general, the diving full face mask is designed to cover all of the wearer's eyes, nose, and mouth, unlike the goggles that cover the eyes and nose. Protects the body's heat loss from cold water temperature.

In addition, the full face mask covers most of the face, so it not only maintains the pressure balance of eyes, nose and mouth when diving, but also protects the face from the contact of fish or seaweed, so the diver can work safely in the water. have.

Such a general diving full face mask is configured as shown in Figure 1, Figure 1 is a perspective view showing a general diving full face mask.

As shown, the diving full face mask 1 has a viewing window 3 at the top to check the outside, and a face mask 2 of rubber material having a nose pocket 4 at the bottom to protect the wearer's nose. It is configured, but the face mask (2) is provided with a regulator (5) for supplying a reduced pressure of the air in the reservoir.

At this time, a strap 6 is provided around the face mask 2 to surround the wearer's head to fix the face mask 2 on the face, and the wearer tightens the strap 6 while pulling the face mask 2. ) Can be adjusted.

On the other hand, both sides of the nose pocket (4) is formed with a finger insertion groove (7) into which the thumb and index finger are inserted so as to hold the nostrils of the nose to shield the nostrils.

The reason for shielding the nostrils by inserting a finger into the finger insertion groove 7 is to solve the tympanic compressive phenomenon in which the tympanic membrane is pushed inward by water pressure when the diver submerges more than 2 m.

More specifically, if tympanic crimp occurs, the eardrum shields the nostrils with a finger, shuts up the mouth, and then blows air into the connector connecting the nostrils and ears.The eardrum is equalized by pressure balance (typically tympanic crimping). The pressure balancing operation to solve this problem is returned to the divers back to the " equalizing "

This tympanic squeezing occurs continuously at a depth of 2m or more due to the nature of the pressure of 1 atm (approximately 1kg) per 10m. In extreme cases, the eardrum may rupture.

Therefore, divers should continuously perform equalizing operation to solve the tympanic crimp when diving more than 2m.

However, the general diving full face mask (1) as shown in the figure is to be inserted into the finger insertion groove (7) recessed internally by a finger, there is a problem that can not be equalized immediately when the tympanic crimp phenomenon occurs. have.

In addition, since the finger insertion grooves 7 should be formed when the face mask 2 is formed, not only the manufacturing of the face mask 2 is very difficult, but also the finger insertion grooves 7 are recessed into the face mask 2. As it is formed and in contact with the wearer's nose, there is also a problem that the wearing feeling is lowered.

The present invention has been devised to solve the conventional problems as described above, provided separately from the face mask and is easily assembled and mounted on the face mask, and when the tympanic crimp occurs during diving, simply press like a button to quickly open and close the wearer's nostrils. It is an object of the present invention to provide a closed device for a full face mask for diving.

And, Figure 8 is an exploded perspective view showing the configuration of the closed closed device shown in Figure 2, Figure 9 is a side cross-sectional view of the closed closed device shown in Figure 2, Figure 10 is a closed The use state side view showing the use state.

In addition, FIG. 11 is a conceptual diagram illustrating a state in which the second lifting bar of the closed closed device shown in FIG. 2 adjusts the coupling height.

As shown in the closed closed device 100 of the full-face diving mask according to the present invention, as shown in Figure 2 has a see-through window 3 and the nose pocket (4) surrounding the nose to check the outside, to supply air The regulator (5) is provided and inserted into a vertical state in the lower face mask (2) of the rubber material for sealing the face of the wearer is assembled.

This closed-closure device 100, that is, the present invention includes a cylindrical housing 50 through which the locking plate 52 protruding in the circumferential direction is inserted through the center of the lower surface of the face mask 2 and caught on the lower surface. do.

At this time, the cylindrical housing 50 is preferably configured to form an insertion hole 2a in the center of the lower surface of the face mask 2 and to insert the cylindrical housing 50 into the insertion hole 2a.

In addition, it is preferable to form an inward protrusion 56 on the upper end of the cylindrical housing 50 so that the stepped portion 74 of the elastic member E and the first elevating rod 70 to be described later is caught. Of course, the inner diameter of the elastic member (E) and step should be formed smaller than the outer diameter of the step (74).

In addition, the present invention is inserted into the outer peripheral surface of the upper end of the cylindrical housing 50 is inserted into the interference fit by the separation preventing means, while the edge 62 is fixed by pressing the face mask (2) on the locking plate (52) Ring 60.

Here, the separation preventing means of the fixing ring 60, for example, to form an elastic protrusion 54 in the circumferential direction on the outer circumferential surface of the cylindrical housing 50, the inner diameter of the fixing ring 60 than the outer diameter of the elastic protrusion 54 To form a small, it was configured so that the fixing ring 60 is caught by the elastic projection 54 by forcing through the fixing ring 60 to the elastic projection (54).

Therefore, the fixing ring 60 penetrates the elastic protrusions 54 while being expanded with self-elasticity as they are fitted to the elastic protrusions 54 by interference fit and permanently under the elastic protrusions 54 while being contracted again after the penetration. Will be caught.

That is, the fixing ring 60 receives resistance from the elastic protrusion 54 when penetrating, but when the fixing ring 60 is pressed with a larger force to overcome this resistance, the fixing ring 60 expands by elastic deformation. While penetrating the elastic protrusion 54, when the penetration is completed is restored to the circular by the elastic restoring force is caught on the lower surface of the elastic protrusion (54).

Of course, the elastic protrusion 54 also contracts slightly while elastically deformed by the pressing force of the fixing ring 60, and is restored to a circular shape again when the fixing ring 60 is completed.

The elastic protrusion 54 has a downward slope by having a shape of upper and lower light, and an inclined surface 64 corresponding to the inclination of the elastic protrusion 54 on the inner circumferential surface of the fixing ring 60. To form, the inclined surface 64 at the time of penetration of the fixing ring 60 was configured to penetrate while sliding the inclination of the elastic projection (54).

Thus, as the fixing ring 60 slides through the elastic protrusion 54, the fixing ring 60 may penetrate the fixing ring 60 with less pressing force.

Meanwhile, the fixing ring 60 penetrates the elastic protrusion 54 and at the same time the face mask 2 of the upper surface of the engaging plate 52 formed on the cylindrical housing 50 as shown in FIG. Pressurizes, thereby the face mask (2) of the rubber material is contracted to the pressed portion.

However, the face mask (2) is supported by the restrained plate 52 is pressed by the opposite side is generated a repulsive force by the self-resilience force to push the fixing ring 60 back to the elastic projection 54, thereby fixing ring 60 is firmly caught on the elastic projection 54 and is permanently fixed on the axis of the cylindrical housing 50.

At this time, if the edge 62 of the fixing ring 60 is formed in a cylindrical shape, it is possible to press the face mask 2 more easily, in this case, the fixing ring 60 by the edge 62 It forms a cap shape.

Here, as shown in Figure 9, the lower surface of the edge 62 of the fixing ring 60 is formed with a wedge wing 65 having a cross-section of the reverse triangle in the circumferential direction, this wedge at the time of fixing the fixing ring 60 It is preferable that the wing 65 is configured to seal the lower surface of the rim 62 while being embedded in the face mask 2 of the upper surface of the engaging plate 52 formed in the cylindrical housing 50.

Then, since the wedge 65 seals along the edge 62 on the face mask 2, airtightness is maintained between the face mask 2 and the fixing ring 60.

Therefore, even if water flows into the insertion hole 2a of the face mask 2, the water does not flow into the outside of the fixing ring 60, that is, inside the face mask 2, by the wedge blade 65.

Again, the present invention is inserted into the cylindrical housing 50, as shown in Figure 8 and 9, a part of the upper end is protruded, the outer diameter of the lower end is formed larger than the upper end has a step (74), the lower portion of the cylindrical housing (50) The packing ring 76 of the rubber material in close contact with the inner circumferential surface thereof is provided, and includes a first elevating rod 70 that is elevated by pressure.

At this time, the outer diameter of the lower end of the first elevating bar 70 is formed larger than the upper end, slightly smaller than the inner diameter of the cylindrical housing 50, between the lower end of the first elevating bar 70 and the inner peripheral surface of the cylindrical housing 50 A gap is formed in the.

However, even if a gap is formed between the first elevating rod 70 and the cylindrical housing 50, the packing ring 76 is in close contact with the inner circumferential surface of the cylindrical housing 50, the interior of the cylindrical housing 50 is hermetic Keep it.

The packing ring 76 is fixed by forming a packing groove (76a) in the lower portion of the step (74) of the first elevating bar (70), it is fixed to fit so as to protrude to the outer peripheral surface of the first elevating bar (70). desirable.

Then, when the first lifting bar 70 is inserted into the cylindrical housing 50, since the protrusion of the packing ring 76 is naturally compressed by the inner circumferential surface of the cylindrical housing 50, it is contracted and inserted into the cylindrical housing 50. Closer contact with the inner circumference.

When the first lifting bar 70 is continuously inserted in all directions of the cylindrical housing 50 while the packing ring 76 is in close contact with the packing ring 76, the stepped jaw 74 is caught by the inward protrusion 56 of the cylindrical housing 50. , Due to this, the first lifting bar 70 cannot be separated from the upper portion of the cylindrical housing 50.

On the other hand, the first elevating bar 70 is configured to be inserted while taking one side of the outer circumferential surface of the cylindrical housing 50 by the rotation preventing means for preventing the rotation to the shaft center, the rotation preventing means is, for example, the first elevating bar 70 Spline groove corresponding to the vertical cutting surface 78 is formed on the inner peripheral surface of the cylindrical housing 50 on the inner peripheral surface of the cylindrical housing 50 to form a vertical cutting surface 78 having a length proportional to the lifting stroke of the first lifting bar 70 on the outer peripheral surface of the upper end of (58) was formed to constrain the rotation of the first elevating bar (70) by engaging the vertical cutting surface (78) and the spline groove (58).

At this time, the vertical cutting surface 78 is formed downward from the upper end of the first lifting bar 70 by the stroke length, as shown in Figure 8, the spline groove 58 is a portion of one side of the inward projection 56 of the cylindrical housing (50) Formed by shielding.

Therefore, the upper end of the first lifting bar 70 and the inward projection 56 of the cylindrical housing 50 take a semicircular shape in plan.

However, the rotation preventing means may be composed of a vertical groove (not shown) facing each other on one side of the upper end of the first lifting bar 70 and the inward projection 56, and a bar key inserted into the vertical groove.

That is, by forming a key groove in the first lifting bar 70 and the inward protrusion 56 and inserting a key in the key groove, the first lifting bar 70 can be prevented from rotating to the shaft center.

The first lifting bar 70 further includes a stopper pin S penetrating an upper end thereof and protruding from both ends thereof to an outer circumferential surface thereof to prevent the upper detachment of the cylindrical housing 50. The upper end of the stopper pin (S) should be formed through the pin hole 70b as shown in FIG.

At this time, the pin hole 70b is formed at a position higher than the upper end of the elastic member E, which will be described later, inserted into the first elevating bar 70, and the inward protrusion of the cylindrical housing 50 that restrains the elastic member E. It should be formed on top of (56).

Therefore, when the stopper pin S is inserted into the pin hole 70b in the protruding state at both ends, the cylindrical housing 50 is constrained at the upper end by the protruding both ends, so that the stopper pin S is not separated from the upper portion of the first lifting bar 70. can not do it.

However, instead of the stopper pin S and the pin hole 70b, a snap ring (not shown) and a snap ring fixing groove (not shown) may be formed in a washer shape.

That is, instead of the pin hole 70b, a snap ring fixing groove, such as a packing groove 76a, is formed therein, and a washer-shaped snap ring is inserted therein in a protruding state, so that the upper circumferential surface of the snap ring with the upper end of the cylindrical housing 50 protruded. It can also be bound to

On the other hand, the first lifting bar 70 further includes a pressing plate 72 protruding in the circumferential direction from the bottom, the user can press the first lifting bar 70 more easily by pressing the pressing plate (72). have.

Again, the present invention is fitted to the outer circumferential surface of the upper end of the first elevating rod 70 to be fixed to the inward projection 56 of the stepped 74 and the cylindrical housing 50, thereby resilient the first elevating rod 70 It includes an elastic member (E) for supporting.

That is, the elastic member E is elastically supporting the first elevating bar 70 while the upper end and the lower end are caught on the stepped 74 and the inward projections 56, and thus the first elevating bar 70 is an elastic member ( It returns to its original position during the elevation by the expansion and contraction of E).

Finally, the present invention is fixed to the upper end of the first elevating rod (70) by being fitted by a coupling means, the upper end is provided with a nose stopper fixing plate 82 having a pair of soft silicon material stopper 90, The second lifting bar 80 includes a second lifting bar 80 that lifts and lifts together when the first lifting bar 70 moves up and down to press the nostrils.

Here, the coupling means of the second elevating rod (80) forms a screw hole (70a) which is horizontally passed through the upper end of the first elevating rod (70), the first elevating rod ( The through hole 80a corresponding to the screw hole 70a of the 70 and the hollow groove 81 into which the upper end of the first elevating rod 70 is inserted are formed, and the first elevating rod in the hollow groove 81 is formed. By inserting the upper end of the 70, and fastening and fastening the fastening member (80b) to the through hole (80a) and the screw hole (70a), the second elevating bar (80) to improve the coupling force with the first elevating bar (70) Configured to maintain or separate.

At this time, it is apparent that the inner diameter of the lower end of the second elevating bar 80 should be larger than the upper diameter of the first elevating bar 70 so that the hollow groove 81 can be formed.

When the inner diameter of the hollow groove 81 is formed to be larger than the upper end of the first elevating bar 70, the outer diameter is naturally formed larger than the diameter of the first elevating bar 70, and thus the elevating of the first elevating bar 70. The outer diameter of the second lifting bar 80 is caught by the inward projection 56 of the cylindrical housing 50 as shown in FIG.

Therefore, the first lifting bar 70 is not separated from the lower portion of the cylindrical housing 50 by the outer diameter and the inward protrusion 56 of the second lifting bar 80.

Of course, the outer diameter of the lower end of the second elevating rod 80 should be larger than the inner diameter of the inwardly projecting protrusion 56, and due to the structure of the rotation preventing means for preventing the rotation of the first elevating rod 70, the second elevating rod 80 The outer diameter of the lower end of the) is inevitably formed larger than the inward projection (56).

Meanwhile, at least one screw hole 70a and the through hole 80a formed in the first elevating bar 70 and the second elevating bar 80 are formed at equal intervals along the axial direction, as shown in FIG. 8. The 70a is formed to have an interval L of 6 to 8mm, and the through hole 80a is preferably formed to have an interval l of 3 to 5mm, and the screw hole 70a and the through hole 80a are formed. The number of is preferably formed, for example, two as shown.

Therefore, to adjust the coupling height of the second elevating rod 80, while lifting the second elevating rod 80 along the axis of the first elevating rod 70, as shown in Figure 11, when the screw hole 70a And the through holes 80a, the fastening members 80b may be fastened.

The reason for limiting the gaps L and l of the screw hole 70a and the through hole 80a to 6 to 8 mm and 3 to 5 mm, respectively, is as follows. When spaced apart, the screw holes 70a become too thin, and as a result, the support force of the first elevating rod 70 supporting the second elevating rod 80 may be lost as the gap between them becomes weak. This is because the part can be broken even with a weak impact.

In addition, when the through hole 80a is formed too far apart, such as the screw hole 70a, the second lifting bar 80 is lifted too much by the gap so that the height of the second lifting bar cannot be precisely adjusted. Because.

The screw hole 70a and the through hole 80a will be described in more detail with reference to FIG. 11. For example, the spacing L and l of the screw hole 70a and the through hole 80a may be 7 mm and 4 mm. Each of the second lifting rods 80 is formed and formed by lifting and fixing the second lifting rods 80 at the first lifting rods 70, as shown in the figures (a) and (b) of FIG. The lifting distance Δ is 3 mm.

Therefore, when the screw hole 70a and the through hole 80a are formed at the intervals L and l as described above, the height of the second lifting bar 80 can be precisely adjusted, and the first lifting bar is also provided. The bearing capacity of 70 can also be satisfied.

On the other hand, the pair of nose stopper 90 of the second elevating rod (80) so as to correspond to the nostril spacing of the wearer, respectively horizontal movement along the nose stopper fixing plate 82 by a horizontal moving means, so as to adjust the space between each other Although the horizontal movement means is formed on both sides of the nose stop fixing plate 82, the guide long hole 82a of which one side is open as shown in Figs. 7 and 8, the elastic shaft 92 is fitted to the guide hole 82a ) Is integrally formed at the lower part of the nose stopper 90, and the elastic shaft 92 is fitted along the guide long hole 82a to move as shown in FIG. 7 to adjust the spacing of the nose stopper 90.

That is, in order to adjust the distance between the nose stopper 90, holding the nose stopper 90, the elastic shaft 92 must be inserted or pulled out again in the guide hole 82a, whereby the nose stopper 90 is the guide hole 82a The distance between each other is adjusted with the guidance of).

On the other hand, the stopper fixing plate 82 is formed so that both sides of the guide hole 82a is formed upward to have a 'V' shape of the alphabet, but formed so that the formed angle (θ) is formed to have an obtuse range, the tip Is formed to have a downward slope to the rear end, the inclination angle (α) is formed to have a range of 5 ° ~ 25 °, so that the stopper 90 fitted in the guide hole 82a is configured to match the nostril angle of the wearer. .

Accordingly, the nose stopper 90 is inclined backward as shown in FIG. 2 by the angle θ and the angle of inclination α, so that the top faces face each other at an angle to each other. It can shield more reliably.

At this time, the angle (θ) is formed within the obtuse range, it is most preferably formed in the range of approximately 110 ° ~ 120 °.

In the closed closed device 100 configured as described above, the diver, that is, the wearer of the face mask 2 when the tympanic compressive phenomenon occurs due to a diving depth of 2 m or more, as shown in FIG. 10, presses the pressing plate 72 of the first lifting bar 70. Press with your thumb.

At this time, the first lifting bar 70 rises while compressing the elastic member E by the pressing force, thereby raising the second lifting bar 80 while shielding the nostril of the wearer with a nose stopper 90.

Then, when the nostrils are shielded, the wearer shuts his mouth and pumps air into the nostrils, thereby inserting compressed air into the connector connecting the nostrils and the ears.

Then, the compressed air is pushed outward by the compressed air, so that pressure equalization, that is, equalizing operation is realized.

When the equalization is completed in this way, the wearer releases the pressing plate 72 of the first lifting bar 70 to release the no-shield shielding state.

At this time, the compressed elastic member E pushes the stepped 74 of the first elevating bar 70 while restoring its own elastic force as the pressing force is released, and thus the first elevating bar 70 is the second elevating bar ( Return to the original position while descending with 80).

If the tympanic compressive phenomenon occurs continuously as the wearer submerges to a deeper depth, the pressing plate 72 may be repeatedly pressed and released to perform an equalizing operation.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea.

Therefore, each component and shape, structure, etc. shown in the embodiments of the present invention can be modified and carried out, and such modifications are naturally belonging to the utility model registration claims of the present invention attached.

The closed face device of the full face mask for diving according to the present invention as described above is not only made separately from the face mask, but also can be easily assembled and mounted on the face mask even if made separately, the face mask for a short time There is an effect that can be easily installed on the image.

And, unlike the conventional way of inserting a finger, the pressurization of the first lifting rod is made of a button type, simply by simply pressing the first lifting rod can open and close the nostrils, the pressing plate of the first lifting rod Since it protrudes easily to the outside of the face mask, it can also quickly cope with the occurrence of tympanic compression.

In addition, since the height of the second lifting bar coupled to the first lifting bar can be freely adjusted, there is also an effect that can be applied regardless of the various nostril height of the wearer, the nose stopper wearer by the angle and the inclination angle of the stopper fixing plate Since the shielding operation is performed while lifting at an angle similar to that of the nostril, that is, similar to the human body structure, there is also an effect of improving the efficiency of the equalizing operation to solve the tympanic crimp phenomenon by shielding the nostril accurately.
