Equipped balancing jacket

Abstract

An equipped balancing jacket including a back and a first stage reducer connected to the compressed air bottle/bottles. From said first stage reducer project high pressure and low pressure hoses. The high pressure hose is directly connected to a computer and/or a manometer, while the low pressure hose is connected to a dispenser from which project the hoses for different functions. Alternatively, the low pressure hose is connected to the said dispenser through the intermediary of an intermediate dispenser, from which it projects also the hose for the connection to the control device.

Description

BACKGROUND OF THE INVENTION

[0001] In the U.S. Pat. No. 6,287,053 filed on Feb. 23, 1999 and issued on Sep. 11, 2001 to the same Assignee, an equipped balancing jacket is described including a back with a first stage reducer, an high and low pressure dispenser and connection hoses, and where from said dispenser project hoses for different functions. Said jacket includes moreover exhaust valves with pneumatic or mechanical control, a manual emergency control and a mouth inflation device.

SUMMARY OF THE INVENTION

[0002] The present invention has as object some improvements to the device forming the object of the above mentioned prior patent, and in particular it refers to a new simplified circuit for the feeding of air at low and high pressure.

[0003] According to the present invention, it is provided for two embodiment forms, one of them involving the use of an intermediate low pressure dispenser, while in a second embodiment form, said intermediate dispenser is eliminated. In both said embodiment forms of the invention, the high pressure air doesn't pass any more through the intermediate dispenser, as it happened in the above mentioned prior patent, but it is connected directly to the use. Thanks to theses features it is obtained the advantage of an assembly less expensive, less heavy, better contained within the jacket.

BRIEF DESCRIPTION OF THE DRAWINGS

[0004] Further features and advantages of the present invention will be better cleared in the following description of some preferred embodiment forms of the same, shown as a not limitative description in the enclosed drawings where:

[0005] FIG. 1 is a front view of a balancing jacket according to a first embodiment form of the present invention;

[0006] FIG. 2 schematically shows the schema of the connections of the jacket of FIG. 1, and

[0007] FIG. 3 schematically shows the schema of the connections according to an embodiment variation of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0008] With reference to the drawings, and with particular reference at first to FIG. 1 and 2 of the same ones, the shown balancing jacket includes a back 1 and one part of textile material similar to the one of the jackets on the market. In the upper part of the back 1 it is the first stage reducer 101 which is connected to the bottle valve (not shown).

[0009] In the lower part of the back 1 it is the first dispenser 201, which is a low pressure (LP) dispenser.

[0010] In the jacket is contained a second dispenser 3 which conveys the air for the second stage 103 or the emergency second stage 203. On the jacket is visible the upper exhaust valve 204. It has also, as quite usual, a second lower exhaust valve (not shown). Said exhaust valves can be both pneumatically and manually controlled. In the schema of FIG. 2 it can be noticed that the first dispenser 201 is connected also to a control group 4 provided with loading 304 and unloading 404 buttons. From the reducer 101 projects an high pressure line, with a manometer or a computer 5. On the shoulders of the jacket are moreover visible the manual emergency control 6 and the mouth inflation 106. With 7 it is indicated the cap for the air exhaustion from the jacket.

[0011] In FIG. 3 is shown and alternative embodiment to the one shown in FIG. 2. To same numerals correspond same parts. According to this embodiment form, the first stage 201 is eliminated, and the control group 4 is connected through the line 401 to a third outlet of the dispenser 3.

[0012] The operation of the described device is the following:

[0013] With reference to the first embodiment form shown in FIGS. 1 and 2, the air coming from the bottle enters the first stage 101, one part comes out of that having a low pressure (LP), one part passes isobarically (HP). The hose LP passing through the inside of the jacket reaches the first dispenser 201, while the HP hose with the high pressure air goes directly to the pressure detector of the computer or to the manometer 5.

[0014] A part of the low pressure air coming from the dispenser 201 passes through the second dispenser 3, from where project the hoses for the second stage 103 and the emergency second stage 203. Eventually the second dispenser can even be absent, in this case the second stages 103 and 203 are connected directly to the first dispenser 201.

[0015] The other part of low pressure air goes to the control group 4.

[0016] According to the embodiment form of FIG. 3, it is eliminated the dispenser 201, then the LP hose goes directly to the dispenser 3, and from that projects a hose 401 leading to the control group 4.

Claims

1. An equipped balancing jacket comprising a back housing, a first stage reducer connected to at least one compressed air tank, wherein from said first stage reducer project the high pressure and low pressure hoses, the said high pressure hose being directly connected to a computer and/or a manometer, while the said low pressure hose is connected to a dispenser from which project the hoses for different functions.

2. An equipped balancing jacket according to claim 1, in which the said low pressure hose is connected to the said dispenser through the intermediary of an intermediate dispenser, from which it projects also the hose for the connection to a control device.
