Description

Technical Field

[0001] The present invention relates to a diving regulator and a gas cylinder including a diving regulator. More specifically, the present invention relates to a diving regulator having a pressure gauge in the field of view and a gas cylinder including a regulator, wherein the pressure gauge is provided on an ergonomic connector. Background Art

[0002] Portable breathing devices are used in emergency situations as well as in recreational diving. The number of equipment required for SCUBA (Self-Contained Underwater Breathing Apparatus) diving, as well as the necessary training and costs, are a major obstacle for many people. Additionally, the transportation, cleaning, maintenance, as well as the volume and weight during the use of the equipment are inconvenient or unpleasant burdens for many people.

[0003] U.S. Patent 4,996,982 to Submersible Systems Inc. discloses a short and compact pressure cylinder with a SCUBA-type regulator attached to the top. The device is easy to operate and is automatically activated by pulling the cylinder out of its quick-release holster in one motion. Pulling the cylinder out of the holster serves to simultaneously remove the mouthpiece cover and open the supply valve in the regulator, allowing air to be supplied to the regulator valve.

[0004] There are many compact SCUBA devices available, including those mounted on a strap and secured to the body, handheld, or held in the user's mouth. It is difficult to know the remaining capacity of these compact SCUBA devices during continuous use.

[0005] There is still a need for a convenient, safe, and portable diving device.

[0006] Any reference in this specification to any prior art is not, and should not be taken as, an admission or any form of implication that the prior art forms part of the common general knowledge. Summary of the Invention

For example, the relative sizes of some elements in the drawings may be distorted to facilitate better understanding of the embodiments of the present invention. Specific Embodiments

[0042] Embodiments of the present invention relate to a diving regulator having a pressure gauge in the field of view and a gas cylinder including the diving regulator.

[0043] The present invention has significant advantages because it provides a diving regulator having a pressure gauge in the user's field of view. Conveniently, the diving regulator can be easily mounted on the gas cylinder, such that the pressure gauge remains in the user's field of view during use due to the pressure gauge being provided on the ergonomic connector.

[0044] The present invention is at least partially based on the inventors' unexpected discovery that a pressure gauge can be positioned in the user's field of view. This has the significant advantage of improving safety since there is no need for the user to use their hands to position and manipulate the pressure gauge into their field of view. Additionally, since the pressure gauge is permanently in the field of view, it always serves as a reminder, so the user does not need to constantly think about checking the remaining breathing gas pressure.

[0045] Prior to the inventors' invention, no regulator, gas cylinder, or breathing device was provided with a pressure gauge in the field of view. The inventors' discovery provides for the first time a safe, convenient, lightweight, and portable diving device that can be used as a primary air source and not just in emergency situations.

[0046] To date, compact SCUBA devices have specifically used pressure gauges mounted on one side of a gas cylinder or a diving regulator, where the gauges are out of sight. Since such conventional devices always position the pressure gauge out of sight or cannot be seen during continuous use of the device, such devices are not suitable for use as a primary air source.

[0047] Due to the innovation of setting the pressure gauge within the inventor's field of vision, this new safety measure means that smaller gas cylinders can be safely used as the primary air source. Previously, such smaller cylinders were limited to secondary air sources, which were only suitable for emergency situations such as when the primary air source fails or other emergency situations when the primary air source is unavailable.

[0048] As used herein, the term "ergonomics" means the coordination of the design of equipment, systems, and physical working conditions with the abilities and requirements of the user. Regarding the ergonomic connector of the present invention, this means that the size of the ergonomic connector is designed to position the pressure gauge within the user's field of vision such that its design is coordinated with the requirement of being easily observable by the user during use in a manner that does not require manipulation of the device relative to the user's body. It can be observed with just a glance.

[0049] Figure 1 An embodiment of a diving regulator 100 including a pressure gauge 200 according to the present invention is shown. In Figure 1 , the diving regulator 100 is shown mounted on a conventional gas cylinder 300 including a container 310. The diving regulator can be conveniently removed and reattached to the gas cylinder 300 or other gas cylinders. The combination of the diving regulator 100 and the gas cylinder 300 provides a breathing apparatus suitable for use underwater for diving.

[0050] As Figure 1 shown, when the gas cylinder 300 is held by the user's mouth, the pressure gauge 200 is positioned such that it is within the user's field of vision.

[0051] The pressure gauge 200 is positioned within the field of vision by being provided on an ergonomic connector 202. As Figure 2 best shown in Figure 2 , the pressure gauge 200 is provided at one end of the ergonomic connector 202. Figure 2In the illustrated embodiment, to achieve such positioning, the pressure gauge 200 includes a bend 204 that is bent at an angle to position the gauge 200 within the field of view. The bend is shown between the adjuster portion 206 and the gauge portion 208 of the ergonomic connector 202. The bend 204 causes the gauge portion 208 to extend in different directions (sideways and upward) in two dimensions to the adjuster portion 206. The side shown in this embodiment is the left side of the user. In other embodiments, the side can be the right side of the user. Although in the illustrated embodiment the two dimensions are sideways and upward, in other embodiments the two dimensional directions can be sideways and downward.

[0052] Those skilled in the art will readily understand, in accordance with the teachings herein, that the phrase "positioning the pressure gauge within the field of view" means positioning the pressure gauge, or at least the display, such that it is within the field of view of the user.

[0053] In Figure 2 In the illustrated embodiment, the angle of the bend is approximately 120°. In other embodiments, the bend can include an angle of 80° to 160°; 90 to 150°; 100° to 140°; or the angle can be 80°; 81°; 82°; 83°; 84°; 85°; 86°; 87°; 88°; 89°; 90°; 91°; 92°; 93°; 94°; 95°; 96°; 97°; 98°; 99°; 100°; 101°; 102°; 103°; 104°; 105°; 106°; 107°; 108°; 109°; 110°; 111°; 112°; 113°; 114°; 115°; 116°; 117°; 118°; 119°; 120°; 121°; 122°; 123°; 124°; 125°; 126°; 127°; 128°; 129°; 130°; 131°; 132°; 133°; 134°; 135°; 136°; 137°; 138°; 139 or 140°. In a particular embodiment, the angle of the bend is 120°

[0054] As Figure 2 As shown, the ergonomic connector 202 is sized such that the pressure gauge 200 is positioned within the field of view of the user and is positioned on top of and to one side of the adjuster 100.

[0055] Turning to Figure 3, the pressure gauge 200 includes a display 230. The display includes a scale 232 and a pointer 234. The scale 232 includes a series of pressure values with markings indicating the values. The pointer 234 points to the value on the scale 232 to indicate the pressure, which is the real-time pressure in the gas cylinder 300. Although not shown, the pressure gauge 200 may include a lens for magnifying the scale or a part thereof.

[0056] Figure 4 and 5 The ergonomic connector 202 before being bent to add the bent portion 204 is shown. According to the teachings herein, a person skilled in the art can easily select a suitable method for adding the bent portion 204 or manufacturing the ergonomic connector 202 with the bent portion 204.

[0057] As Figure 5 shown, the ergonomic connector 202 is provided with airtight attachments at both its diving regulator end and its pressure gauge end. The airtight attachment at the diving regulator end includes a plug 210 for airtightly attaching to the regulator block 104 and a regulator seal 212 for airtight sealing with the regulator block 104. The regulator seal 212 may include a gasket such as an O-ring. The ergonomic connector 202 further includes a regulator connector 214 attached to the regulator block 104. The regulator connector 214 may include a thickened area. The ergonomic connector 202 includes a tube 216, and the tube 216 includes an air passage 218 in fluid communication with the regulator block 104 and thus also in fluid communication with the gas cylinder 300. The ergonomic connector 202 further includes a gauge connector 220 for attaching to the pressure gauge. The gauge connector 220 includes a seal 222 in the form of a gasket shown as an O-ring. The tube 216 may be made of stainless steel.

[0058] The ergonomic connector 202 permanently and fixedly positions the pressure gauge 200 within the user's field of view.

[0059] Figure 5 and Figure 6 The ergonomic connector 202 before being bent to add the bent portion 204 is shown. In the illustrated embodiment, the ergonomic connector 202 has a length of 7 cm. Figure 5 Only a part of the length of the ergonomic connector 202 is shown, and this part of the length is visible outside the connection device 214 connected to the diving regulator 100 and outside the connection device 220 connected to the pressure gauge 200 respectively. In the illustrated embodiment, the exposed length of the regulator portion 206 is about 1.5 cm, and the exposed length of the gauge portion 208 is about 2.5 cm.

[0060] In accordance with the teachings herein, one skilled in the art can easily select the size of the ergonomic connector 202 such that it positions or sets the pressure gauge 200 or at least the display 230 within the user's field of view. In this regard, the absolute and relative sizes of the diving regulator 100 and the pressure gauge 200 or at least the display 230 may need to be considered. Suitable lengths for the ergonomic connector 200 can include from 2 cm to 20 cm; from 3 cm to 15 cm; or from 5 cm to 10 cm. For example, the length can include 2 cm; 3 cm; 4 cm; 5 cm; 6 cm; 7 cm; 8 cm; 9 cm; 10 cm; 11 cm; 12 cm; 13 cm; 14 cm; 15 cm; 16 cm; 17 cm; 18 cm; 19 cm or 20 cm. The exposed length of the regulator portion 206 can be from 0.5 cm to 5.0 cm; from 1.0 cm to 4.0 cm; or from 1.25 cm to 1.75 cm. The exposed length of the gauge portion 208 can be from 1.0 cm to 6.0 cm; from 1.5 cm to 5.5 cm; or from 2.0 cm to 3.0 cm.

[0061] The pressure gauge 200 also includes a measurement channel 224 in fluid communication with the air passage 218 for determining pressure. The determined pressure is then displayed on the display 230.
