Abstract:
System for rapid release of a weight usable by a diver, comprising: said weight (2); a housing (3) constrainable to the diver and in which the weight (2) is placed; said housing (3) comprising an extraction opening (30) for extracting the weight (2) from the housing (3); an anchorage (4) and a seat (5) in which the anchorage (4) may be positioned, said seat (5) being constrained to the housing (3); the anchorage (4) is constrained to the weight (2). The anchorage (4) is removable from the seat (5) to allow the removal of the weight (2). The seat (5) has a first inlet/outlet mouth (511) for the anchorage (4) which is at least partly turned not towards the extraction opening (30) for extracting the weight (2) from the housing (3), but in the opposite direction.
Abstract:
A command and control assembly for inflating and deflating a hydrostatic balancing jacket includes a primary supply duct connected to an end of an air chamber of the jacket and provided, at the opposite end, with a hand piece having a mouthpiece device. A connection socket is provided on the hand piece, which is in fluid communication with a secondary supply duct connected to a compressed air tank, and a pneumatic actuation duct actuates a discharge valve of the jacket, which is in fluid communication with the secondary supply duct. Control systems of the delivery from the secondary duct, of the delivery to the pneumatic actuation duct, and of the delivery from the mouthpiece are arranged on the hand piece.
Abstract:
A second pressure-reducing stage for underwater use includes a supply duct of a breathable gas, in which a valve of a pressure reducing device to reduce the pressure of the breathable gas is provided, the valve being interposed between an inlet of the supply duct and a suction/exhalation mouth to suction/exhale the breathable gas; a casing containing a pressure-sensitive device to control the opening/closing of the valve, the supply duct and the suction/exhalation mouth leading into the casing; and a bypass duct for supplying at least part of the flow of the breathable gas from the supply duct, downstream of the valve, directly into the suction/exhalation mouth, the by-pass duct joining the suction/exhalation mouth through an opening having an axis oriented in a direction which converges towards the axis of the suction/exhalation mouth.
Abstract:
A shoulder strap for devices adapted to carry loads, particularly on the back of a user, has a side widening toward the sternal area of the user and an arched shape, the dimensions and shapes being designed so that in worn condition the side widening can rest on the thorax area, below the cervicothoracic imaginary line and above the breast, while the section extending downward beyond the side widening overlaps the side area of the thorax, the breast being positioned in the area next to a concave side edge that bypasses the breast. A buoyancy compensator for diving comprising equipped may be equipped with one or more shoulder straps as described.
Abstract:
Swimming goggles include two eyepieces with a substantially cup-like shape, a bridge element connecting the two eyepieces at the nose, a strap wrap the head, couple the outer ends of each eyepiece and keep the goggles in place when in use, wherein each of the two eyepieces includes at least one polygonal plan shaped flat front lens or wall and a shell wall composed of a set of polygonal plan shaped flat lenses joined to each other, along adjacent contact edges, and with the peripheral edge of the at least one flat front lens or wall to delimit a reduced volume inner chamber, which is completely open towards the rear part of the eyepiece, that is, towards the eye.
Abstract:
A method for for assessing severity of an underwater dive includes calculating a dive severity index by: (a) determining the gas breathed by the diver; (b) measuring the dive time; (c) determining the depth profile of the dive; (d) calculating a dive severity index based on a function of steps (a), (b) and (c); and (e) assessing severity based on the dive severity index calculated in step (d), wherein the steps (a), (b), (c), (d) and (e) are carried out in real time, at each instant of the dive time of the diver, and step (d) is performed according to the formula: DSI=k1*f(GAS)*f(D)*f(T), where: DSI is the dive severity index, k1 is an arbitrary constant, f(GAS) is a function of the inhaled gas, f(D) is a function of the dive depth, and f(T) is a function of the dive time.
Abstract:
A device for reversibly connecting together a first element and a second element designed to be alternately connected and disconnected includes a male element, inserted into a female element to move from a mutually disengaged state to a mutually engaged state, and a slider, for actuation/release of the engaged state, which is slidingly engaged by the male element into the female element. The relative movement of the actuation/release slider and the male element is transferred to first releasable locking members of the male element, which cooperate with corresponding second locking members of the female element to move from a stable locked state to a stable unlocked state of the male element by a movement of the slider in the direction of insertion. Furthermore, the male element includes a handle having the slider at least partially and slidingly housed therein.
Abstract:
A shut-off member of a pressure reducing valve of a pressure regulator device, such as a diaphragm-type first stage for scuba diving, includes an enlarged head connected to a shaft and cooperating with a valve seat that separates a chamber supplied with high pressure gas from a chamber in which gas is at a lower pressure. The enlarged head and an end section of predetermined length of the shaft, connected to the enlarged head, are seamlessly coated with at least one layer of elastomeric material. Such coating of elastomeric material is limited to an end portion of the shaft connected to the enlarged head and the coated shaft portion is entirely contained in the high-pressure chamber in any operating position of the shut-off member.
