Description

Underwater sports equipment and bridge piece

Technical Field

The invention relates to underwater sports equipment, in particular to floating and diving equipment with a breathing function for one mouth and one nose.

Background

As shown in fig. 1A, except for a Full-face mask, i.e., a Full-face snorkel mask, FFSM, most nine existing diving masks 1 cover eyes, noses and mouths only, and generally include a frame 2, two lenses 3 respectively disposed on left and right eyes (or a lens portion integrally formed with the two lenses), and a skirt portion 4 extending rearward. The frame 2 is made of hard material, and the skirt 4 is made of flexible material such as silicone, and not only extends backward along the frame 2, but also is integrally formed in the nose region to form a nose bag 5. When a user wears the diving mask 2, the skirt part 4 can just surround the eyes to the middle part of the person below the nostrils to form a circle, so that the air-tight and water-proof effects of the eyes and the nose are achieved, the breathing work is carried out through the mouth part (M), namely, the mouth part (M) bites the occlusion part 8a (shown in figure 1B) of the mouthpiece 8 of the breathing tube 7, the mouth part (M) can be communicated to the atmosphere through the top part 7a to breathe, and air exhaust and water drainage are carried out through the water drainage valve 7B below the suction tube 7.

The design can only breathe by the mouth (M), and is obviously contrary to the habit that the ordinary people still like breathing by the nose or breathing randomly by the mouth and the nose, so that the pleasure of snorkeling is obviously reduced. In addition, when the nose is sealed in the face mask 1, the face mask 1 is slightly separated from the seal and water enters because the nose is mistakenly used for breathing forcefully, and under the conditions of water drainage skill and hurry and tension without proper mouth spitting, a user often unconsciously adjusts or moves the face mask by hands under water, thus choking water and being very unsafe.

Therefore, designing a mechanism which can block the water from entering the nose and can breathe freely through the mouth and the nose is a great breakthrough in water activities (particularly floating and diving), which is a goal pursued by the industry.

Disclosure of Invention

Based on the existing design, the mask and the breathing tube are two separated parts, the mask is airtight, and the breathing tube can be ventilated, so that the mask and the breathing tube can be in gas communication, and the aim of pursuing free breathing of mouth and nose can be achieved. The invention sets up a hollow air bridge between the proper position above the mouthpiece of the respiratory tube and the position aligning with the nostril of the mask area, has the shortest stroke and the most direct effect of nose ventilation, and can achieve the excellent ventilation effect of the nose without detour.

In the selling process of the product, because only one air bridge part is added, the volume of the package cannot be increased, and the product is not boring like a traditional mask when being displayed and displayed, but becomes a standard board with the functions of a mask with a nose capable of breathing freely, a mask with a nose capable of floating and submerging freely in the air and the like, the traditional mask is obviously jumped off, the eyes are naturally sucked, and the discussion degree and the purchase desire are greatly improved.

The main object of the present invention is an underwater motion equipment, comprising: a mask having a cavity for receiving the eyes and nose of a user, the nose and mouth of the user being water-tight isolated from the outside; a breathing tube, which is provided with a tube body and a mouthpiece extending from the side edge of the tube body, wherein the mouthpiece is provided with an occlusion part for a user to breath when the user is contained in the mouth of the mouthpiece; a bridge member connected between the mask and the breathing tube to place the interior of the breathing tube in fluid communication with the cavity of the mask so that the user's nose can inhale or exhale through the breathing tube.

It is a further object of the present invention to provide a bridge for connecting a mask for underwater exercise to a breathing tube separate from the mask, wherein the interior of the breathing tube is in fluid communication with the outside, and the interior of the mask is in fluid communication with the outside through the bridge and the breathing tube.

Detailed Description

Referring to fig. 2A, an underwater sporting apparatus comprises: a mask 10, a breathing tube 20 and a bridge 30a. The mask 10 has a cavity 11 for receiving the eyes and nose of a user, and when the mask 10 is worn by the user, the nose and mouth of the user are sealed from the outside in a waterproof manner. The mask 10 has a glasses portion 12 and a waterproof skirt portion 13, the waterproof skirt portion 13 extends outward from the glasses portion 12 and defines the cavity 11 together with the glasses portion 12, as shown in fig. 2B. The waterproof skirt 13 extends forward of a nose pocket 131 in a central region of the lens portion 12. A rear peripheral edge 133 of the waterproof skirt 13 is adapted to provide a waterproof fit to the face (F) of the user when the user wears the face shield 10 and tightens the head straps 14 connecting the two sides of the eyewear portion 12 around the user's head. The respiratory tube 20 has a tube body 21 and a mouthpiece 22 extending from the lower side of the tube body 21, the mouthpiece 22 has a mouth-engaging portion 221 for a user to breath in his/her mouth, as shown in fig. 2C. The mouthpiece 22 further has a connecting portion 222 connecting the mouthpiece 221 and the body 21 of the breathing tube 20, so that the mouth of the user can suck fresh air through the top 24 of the breathing tube 20, and discharge a part of dirty air and spit out accumulated water through the drainage valve disposed at the bottom 25 of the breathing tube 20.

Referring to fig. 2A, 2B and 2C, the key point of the present invention is that a first opening 134 is disposed below the nasal cavity 131, a second opening 224 is disposed above the connecting portion 222, and the bridge 30a is connected between the first opening 134 and the second opening 234, such that the interior of the respiratory tube 20 is in fluid communication with the nasal cavity 131 through the bridge 30a. Of course, the positions, numbers and types of the first openings 134 and the second openings 224 may be changed without limitation. Accordingly, because the bridge 30a is connected between the mask 10 and the breathing tube 20, the interior of the breathing tube 20 can be in fluid communication with the cavity 11 of the mask 10, and the nose of the user can inhale or exhale through the breathing tube 20. It should be noted that the bridge 30a may be integrally formed with the mask 10 and the breathing tube 20, or may be partially integrally formed. For example, it is feasible to form the bridge 30a integrally with the nasal pocket 131, or with the connecting portion 222, or with both.

Generally, the nose bag 131 of the mask 10 and the mouthpiece 22 of the breathing tube 20 are both elements that contact the human body, and also have a waterproof property, and therefore, a soft material, such as silicone, is selected for the bridge member 30a connected therebetween, and therefore, a hard material, such as a hard material with shore hardness D65 to D85 (or, but not limited to, a harder soft material with shore hardness a50 to a 95) is suggested, so that the connection between the parts with different hardness can be achieved by using, for example, a barb fitting (hose fitting) method to directly fit the softer material end 27 into the opposing harder material end 31, as shown in fig. 2A, so as to easily achieve the waterproof joint. Of course, the connection of the softer material end to the harder material end is convenient and the material is simple, but it is not necessary to adopt this method, and any other method that can achieve waterproof connection, such as adding a gasket to the two screwed hard material ends, etc., can be used instead.

Fig. 3A and 3B show another type of bridge 30B, preferably the bridge 30B is also made of a hard material and has a circumferential corrugated sidewall 32 to conform to the curved shape required for the waterproof connection between the nasal bag 131 and the connecting portion 222. When the underwater motion device is worn by a user, the mask 10 and the breathing tube 20 can be engaged and cushioned more effectively according to the face shape of the user. Fig. 3C shows a schematic airflow state in which the bridge 30b is installed between the mask 10 and the breathing tube 20, and the airflow discharged from the nose (N) of the user can pass through the bridge 30b and enter the tube body 21 of the breathing tube 20 together with the airflow discharged from the mouth (M). The same applies to the inspiration and is not indicated.

For better cushioning and flexible bending, the distance between the nose bag 131 and the connecting portion 222 can be increased, i.e. another bridge 40 as shown in fig. 4A and 4B, and the corrugated sidewall 43 can be partially disposed on the inner side of the bridge 40, so that the bridge 40 can be bent to follow the face shape. In addition, to form a better abutting relationship between the soft material and the hard material, the bridge 40 may also be made of materials with different hardness, such as hard material with shore (shore) hardness D65 to D85 (or, but not limited to, harder soft material with shore hardness a50 to a95 or above) for the two end regions 43a, 43b, and a softer material for the region with the middle corrugated sidewall 43, which are integrally coated and injection molded. In addition, because the mouthpiece 22 is a component directly contacting human body fluid, the user has a cleaning concern, and the soft mouthpiece 22 is connected to the lower part of the hard type breathing tube 20 by means of barb fitting (hose barb fitting), so that as shown in fig. 4C, the tongue piece 225 can be added to the tail end of the connecting part 222 of the mouthpiece 22, which is more convenient for the user to pull up and detach, clean or store the mouthpiece, and even can be used without exchanging with other people, which is more sanitary.

Of course, the bridge can be divided into several elements according to the same concept, as shown in fig. 5, which includes a main body 53 and an upper joint 53a and a lower joint 53b which are respectively in waterproof connection with two ends of the main body 53, wherein the main body 53 is a flexible and bendable soft material, and the upper joint 53a and the lower joint 53b are inflexible or slightly flexible harder materials. This also provides a soft-hard water-tight joint at each joint.

In concept, when a user wears a conventional mask and breathes through the mouth via a breathing tube, the lens in the mask is less likely to fog because the mask is isolated from the outside air and the nose in the mask does not spit hot air, but if the interior of the mask is communicated with the outside, the nose starts to operate and breathe, and the spitting warm air is more likely to fog the lens in the mask. To solve this problem, it can be reinforced from two places: first, as shown in fig. 6A and 6B, a partition 138 is disposed at the upper edge of the inner side of the nose bag 131, and is disposed to divide the cavity 11 into an upper chamber 11a and a lower chamber 11B, when the user wears the mask, the upper chamber 11a for accommodating the eyes (E) of the user and the lower chamber 11B for accommodating the nose (N) of the user are substantially isolated by gas, so that the hot air generated from the nose bag 131 does not enter the upper chamber 11a to interfere with the lens 17, thereby causing fogging. The second place that can be strengthened is to divide the inlet and outlet gas. In a specific embodiment, referring to fig. 7A and 7B, a partition 55 is disposed inside the upper connector 53a to form two channels, and the two channels are respectively provided with an air inlet check valve 56 and an air outlet check valve 57, so that the air inlet flow and the air outlet flow entering the nasal cavity 131 can be separated. When the nose is breathing, the dirty warm air is exhausted from the exhaust check valve 57 through the bridge 50 to the top 24 and bottom 25 of the snorkel 20 and does not return to the nose bag 131. The nasal bag 131 can only receive clean, cool air from the inlet check valve 56, which naturally reduces the chance of fogging of the lens 17. Of course, the above-mentioned air intake and exhaust branch measures do not need to be provided in the upper joint 53a, and other positions, such as the lower joint 53b, the opening 634 under the main body 53 or the nose bag 131 (as shown in fig. 6A), are also possible.

In addition to the above-mentioned preferred embodiments, the structure and operation of the means for implementing the invention are described in detail, so as to make the scope of the invention more clear, but the claims of the end section should not be limited by the description.
