Definitions

  • the present invention relates to balancing jackets for diving activities, and in particular to balancing jackets equipped with horseshoe-shaped inflatable bladder, i.e. comprising two parallel arms joined one to the other in a U shape by means of an intermediate bladder portion.
  • the present invention relates to a balancing jacket equipped with horseshoe-shaped bladder, in which said bladder further comprises two inflatable ventral extensions obtained as one piece together with said bladder.
  • jackets having a floating area placed both in the ventral and lateral portions and also on the shoulders. Also known are the so-called “back-mounted” jackets having a front area carrying the harness and an inflatable area which is placed on the back portion. Both types of these jackets are disadvantageous because they lack in stability in water. In particular, "back-mounted" jackets tend to push forward the diver's body with his head down, which can be very dangerous if the diver is tired.
  • the object of the present invention is therefore a balancing jacket for diving activities equipped with a horseshoe-shaped inflatable bladder placed on the back, which envelops the bottle and therefore gives the diver a lower hydrodynamic resistance with respect to the one given by conventional back-mounted jackets extending outside the bottle.
  • said bladder is provided with ventral inflatable extensions obtained as one piece, the user is given an extremely comfortable and safe floating trim (the diver "sits as in an armchair" in the jacket).
  • the jacket according to the invention comprises an inflatable chamber consisting of a base element substantially having a plan C-shape, the central portion of said base element being shaped as a U by applying a textile back element whose shape is complementary to the U, thus obtaining a horseshoe structure with two end portions extending forward substantially as a right angle starting from said horseshoe structure, thus forming the ventral floating chambers.
  • said back element shaping the whole structure is preferably made of a net fabric, so as to further reduce the hydrodynamic resistance of the assembly.
  • Another object of the present invention is a method for manufacturing a jacket as mentioned above.
  • Figure 1 shows a plan view of the element 1 constituting the air chamber of the jacket according to the invention.
  • element 1 has a plan contour substantially shaped as C and consists of two sheets of air-proof fabric, which are joined one to the other along their edges.
  • Said element 1 can be in itself the inflatable air chamber of the jacket, or it can be provided inside - in quite a common way - with a second air-proof bladder (generally a plastic bladder) constituting the air chamber of the jacket.
  • the outer bladder can also be made by sewing together several textile elements also in a non-air-proof way, since the air chamber function is performed by the inner bladder.
  • the base element 1 in Figure 1 is given its final shape, shown in Figure 2, by sewing and/or joining its intermediate edge with a U-shaped piece of fabric 2 constituting the frame shaping the jacket, which thus takes on a horseshoe shape 101 in its back portion, with two enveloping extensions or arms 3, 103 extending forward starting from the horseshoe back, almost as arms of an ideal arm-chair.
  • the piece of fabric 2 consists of a net fabric.
  • the back support 6 Onto the piece of fabric 2 the back support 6 is mounted, which can be stiff or soft, or of any other type.
  • Said back support contains the harness shoulder straps 4, provided on their ends with fast coupling elements cooperating with complementary coupling elements applied onto the ends of two belts fastened to the air chamber elements 3, 103.
  • To the back support 6 it is also possible to fasten the rear back (not shown), to which the bottle 8 ( Figure 4) is hanged, for instance by means of the belt 7.
  • the belts 9 are fastened to the ends of the two ventral extensions 3, 103, thus closing the front portion of the jacket in the area of the diver's belt.
  • Said belts 9 are advantageously provided with Velcro-type or similar connecting elements, though they can also be provided with fast coupling buckles.
  • two pockets 10 which might be used to house ballast lead, can be applied onto the outer side of the ventral extensions 3, 103.
  • the jacket further comprises discharge valves (only one of them being shown, referred to with numeral 11), the inflating valve (not shown) which can be arranged on the front side of one of the ventral extensions 3, 103, and all those other accessory elements required for such a jacket.
  • the jacket according to the invention develops around the air bottle 8 enveloping it almost as in a niche, so as to minimize the hydrodynamic resistance of the assembly.
  • the diver When the diver is floating, he is kept by the jacket in a very comfortable position, as if he were sitting in an armchair. Beyond being comfortable, this position is also quite safe in case the diver should be taken ill, since his whole weight is kept out of water, without risking being pushed with his head under water as could occur with some types of back-mounted jackets.
  • the chamber 1 of the jacket consists of "two sheets or two pieces of fabric” joined one to the other
  • the general expression "two sheets or two pieces of fabric” also includes the fact that said sheets or pieces forming the chamber 1 can also be obtained from two plane fabric elements obtained by joining several lengths of fabric and then by cutting them so as to form the final sheet or piece with the plan contour according to the invention.
  • said lengths will be of air-proof fabric and will be joined one to the other in an air-proof way, whereas in case the chamber 1 contains a second air-proof bladder constituting the air chamber of the jacket, said lengths can be joined one to the other also in a non-air-proof way.
  • the main portion of the horseshoe-shaped inflatable bladder of the jacket according to the invention is disposed in use in the dorsal portion of the user, with the addition of two lateral inflatable extensions. Frontal inflatable portions are absent.
  • the inflatable bladder extends "backwards" from the upper dorsal portion of the back of the jacket, that is it extends toward the air bottle.
  • the inflatable portion extends "forwardly" from the back of the jackets thus causing, when the jacket is completely inflated a pressure against the dorsal zone of the diver.
  • the said drawback is completely obviated by the jacket according to the invention which, as said, is inflated "backwards" with respect of the back of the jacket.
  • a further advantage of the jacket according to the invention resides in the true buoyancy thrust afforded.
  • a portion of their inflatable bladder is above the water surface. It will be evident that the portion of the inflatable bladder which is above the water surface will not contribute to the buoyancy of the diver, so that if a jacket is used with, for instance, a maximum buoyancy of, say, 20 kg, the effective buoyancy will be in the order of 17-18 kg, according to the shape of the jacket.
  • the buoyancy thrust of the jacket will be always completely used.
