description

The invention relates to a diving equipment, comprising a compressed air cylinder, which is in communication with a respirator, and an inflatable vest over which buoyancy is ausarierbar by the vest in normal operation with the compressed air cylinder for inflating or with a Auslass for discharging air is connectable , wherein a control device is provided, which via a control valve in response to a surrounding

Water pressure is activated and has a time control unit, which after a defined time and in the absence of a respiratory activity on the breathing apparatus in a

Conveyed emergency operation and controls an emergency valve via a control line, which connects the vest with the compressed air cylinder and thus forces an inflation of the vest.

Modern diving equipment usually includes a buoyancy compensator, also BCD

(Buoyancy Controll device), which serves as a support frame for a compressed air cylinder of diving equipment and with the help of which the diver at any depth by blowing or discharging air exactly regulate his buoyancy and balance.

In general, a plurality of valves are provided in a BCD, which are provided for controlling the blowing or discharging of air into an air bubble of the vest and often also for the initiation of emergency measures. These emergency measures, for example, in the case of falling below a defined amount of compressed air in the

Compressed air cylinder or initiated in the absence of breathing activity of the diver.

WO2007 / 058615 A1 discloses a diving equipment, which is composed of a buoyancy compensator and a compressed air cylinder, as well as a valve arrangement for controlling a compressed air supply from the compressed air cylinder to the buoyancy compensator. About the l BCD is compensated for a buoyancy of a diver by the vest inflated in normal operation either via the compressed air cylinder or compressed air is released from the vest. The valve arrangement in this case comprises a control device, by means of which can be changed over from the normal operation in an emergency operation. For this purpose, a control valve is provided which activates the control device in dependence on an ambient water pressure. The control device has a time control unit, which is composed of a diaphragm valve and delay means. Upon activation of the control device via the control valve, the diaphragm valve is acted upon with compressed air from the compressed air cylinder and forwards the compressed air via a first working line to the delay means. If a breath is now taken by the diver on the breathing apparatus, the compressed air conducted to the diaphragm valve is continued via a second working line to the delay means, the pressure supply via the second working line resetting the

Delay means causes. However, the diver takes over one, through the

Delay means defined period of time no breath from the breathing apparatus, the delay means actuate a control line an emergency valve, which thereby connects the vest with the compressed air cylinder and thus forces their inflation. As a result, the supposedly non-breathing diver is then transported back to the water surface. Based on the above-described prior art, it is now the object of the present invention to provide diving equipment in which functions of the control device can be manually influenced by the diver, whereby this influence should be as easy as possible to be brought about by the diver.

This object is achieved on the basis of the preamble of claim 1 in conjunction with its characterizing features. The following dependent claims give advantageous developments of the invention. According to the invention, diving equipment comprises a compressed air cylinder communicating with a breathing apparatus and an inflatable vest over which buoyancy of a diver can be balanced. For this purpose, the vest may be connected to the compressed air bottle for inflating in normal operation or air is vented from the vest via an outlet. In addition, a control device is provided, which via a Control valve is activated in response to a surrounding water pressure and has a time control unit, said time control unit after an expiry of a defined time and in the absence of a breathing activity of the diver transferred to the breathing apparatus in an emergency operation. In this case, an emergency valve is controlled via a control line, so that the vest connected to the compressed air cylinder and an inflation of the vest is enforced.

For the purposes of the invention, the time control unit is composed in particular of a filler panel, a control volume and an emptying valve, wherein the

Control volume from activation of the control device through the control valve via the filler panel is continuously filled with compressed air from the compressed air cylinder and thereby communicates with a control line of the emergency valve. From reaching a defined pressure in the control volume, this ensures a corresponding actuation of the

Emergency valve, which as described above forces the inflation in the vest. In the case of a breath of the diver on the breathing apparatus, however, the emptying valve is actuated, thereby enabling an emptying of the control volume. Consequently, the

Time control unit reset on each breath by emptying the volume. For the purposes of the invention, an activation of the control device by the control valve by the control valve by the surrounding water pressure in relation to a

Reference pressure, preferably the atmospheric pressure is set and when a pressure threshold is exceeded by the surrounding water pressure, the control volume of

Time control unit is connected to the compressed air cylinder.

The invention now includes the technical teaching that an inflation valve and a drain valve are provided, wherein the inflation valve when manually operated by the diver the vest with the compressed air cylinder and the drain valve with manual control by the diver the vest with the outlet for venting air the vest connects. Over these valves a balancing is thus made by filling or emptying the vest. As a special feature, at least one control valve is additionally provided, via whose respective actuation during the dive the control device and / or the control valve can be influenced. In other words, therefore, at least one additional control valve is provided, via which when actuated by the diver on the

Control valve is acted upon. Alternatively or in addition thereto, the control device is influenced upon actuation of the at least one control valve. Such

Design here has the advantage that the diver thus on the at least one Control valve on the activation of the control device and / or on the

Monitoring function of the control device act and this targeted

Adjust conditions that exist in each dive. In contrast to this, WO2007 / 058615 A1 has an influence on the

Control device or the control valve of the BCD not possible. However, this has the consequence that when the time range is exceeded in the time control unit without making a breath on the breathing apparatus, for example due to intentional stopping of breathing or certain exercises in the dive training, always inflating the vest and a return to the water surface is caused. If the vest inflates once, then this process can reach the

Water surface can not be stopped. Also a manual reset of the

Time recording in the delay means is not possible. According to an advantageous embodiment of the invention, the respective actuation of the at least one control valve is coupled at least at a defined degree with an actuation of the inflation valve and / or with an actuation of the drain valve. This has the advantage that on the usually in the range of a buoyancy control already provided elements in the form of an inflation valve and a drain valve on the

Control device and / or the control valve for activating the control device can be acted without the separate controls must be provided. The diver can thus make an influence on the safety functions of the respective BCD with the valves familiar to him, which simplifies the operation accordingly and an excessive demand of the diver in the individual case due to a large number of

Controls prevented. Furthermore, with a corresponding assignment to the inflation valve and the drain valve, easy control is possible, which can be done intuitively by the serving diver. Finally, the interventions in the safety functions of the vest can possibly also be carried out by a dive partner, since they can be operated easily accessible from the outside and easy to find. Finally, the production cost for forming a diving equipment can be lowered, since separate buttons, which would otherwise have to be provided for resetting the safety functions, can be saved. In a further development of the invention, the drain valve can be actuated via an actuating element, wherein in a first half of a control range of the actuating element an actuating movement of the actuating element coupled only with a displacement of the drain valve and from a second half of the control range, the actuating movement additionally with a displacement of the at least one control valve is. By means of such a configuration can be controlled by the degree of actuation of the actuating element, if only one control of the

Discharge valve for balancing a buoyancy or whether additionally the

Control device is to be influenced in order to perform the aforementioned functions such as resetting and / or cancellation of inflation of the vest. The diver can therefore centrally control the type of actuation of the control element, whether he functions in the

Normal operation or whether it in addition to changes to the

Want to make control.

According to the invention, the at least one control valve is designed as a check valve, which is provided between the emergency valve and the compressed air cylinder and interrupts the connection between the emergency valve and compressed air cylinder in an actuated position. In this case, the blocking valve is preferably coupled to a movement of the drain valve, at least as of a defined degree of actuation of the drain valve. As a result, an initiated in an emergency operation inflation of the vest can thus be canceled by the pressure supply to the emergency valve is interrupted via the check valve. When coupled to the drain valve, the diver can manually perform this break by operating the drain valve since the check valve is coupled to the drain valve at least at a certain degree of actuation of the drain valve. Preferably, the check valve is configured here as a 2/2-way valve, which in a basic position allows a flow of compressed air to the emergency valve and in an actuated position interrupts the connection. Of

Further, the check valve is in coupling with the drain valve in particular mechanically, for example via a corresponding linkage, connected to the drain valve, in the context of the invention, however, a pneumatic, hydraulic or electrical coupling is conceivable.

According to a further embodiment of the invention, this is at least one

Control valve designed as a reset valve to which branches off from the control line of the emergency valve, a working line and the pressure in an actuated position relieves the control line. In particular, this reset valve is then at least from a defined Degree of actuation of the drain valve coupled with a movement of the drain valve.

Advantageously, a timeout procedure in the time control unit is reset by actuation of the reset valve by the pressure relief. So it can by the

Reset valve the time counting in the time control unit, which after the last, on

Respirator is breathed, restarted, the diver can control this restart in case of coupling with the drain valve by operating the drain valve manually. In the case of the design of the time control unit with a volume and a directional control valve, the volume is drained upon actuation of the reset valve, causing the desired reset. The reset valve is in the sense of the invention in particular mechanically coupled to the drain valve, but may as well also be pneumatically, hydraulically, electrically or otherwise connected to the movement of the drain valve. With provision of a reset valve in addition to that in advance

described blocking valve, these two valves can be coupled in particular via a common linkage with the drain valve, so that a control of the drain valve causes at least at a certain degree an actuation of the check valve and the reset valve. Furthermore, the reset valve is preferably designed as a 2/2-way valve.

According to the invention, the at least one control valve is designed as a reset valve, which is placed between the control valve and the compressed air cylinder, wherein the reset valve connects in a basic position a working line of the control valve with the compressed air cylinder and depressurizes the operating line of the control valve in an actuated position.

Preferably, the reset valve is actuated together with the inflation valve at least at a defined degree of actuation, so that in the sequence a supply to

Control valve is depressurized. Such a configuration has the advantage that by providing the reset valve and the pressure-less switching of the supply to the control valve, a monitoring function of the control device can be switched on again after an interruption, the diver can make this switching on when operated with the inflation manually via the inflation valve. A coupling between the inflation valve and the reset valve is in this case again preferably designed mechanically, but can also be provided hydraulically, pneumatically, electrically or in another manner in the context of the invention. Furthermore, the reset valve is configured in particular as a 3/2-way valve, which in a basic position connects an inflow to the control valve with the compressed air cylinder and in an actuated position the inlet to the control valve with a non-pressurized line to the vest. In a further development of the invention, the at least one control valve is formed by a check valve, which is arranged between the control valve and the time control unit. In this case, the check valve can be moved to a blocking position in which a connection between the time control unit and the control valve is interrupted, whereas the check valve, the connection between the time control unit and control valve in a

Basic position manufactures, in which the check valve via a connected to a drain side of the inflation valve control line can be transferred. Such a configuration has the advantage that via the check valve, a temporary interruption of the

Breath monitoring function can be brought about, wherein the monitoring by the time control unit is then activated again from a renewed actuation of the inflation valve. Thus, for example, when making underwater photographs and a usually associated stopping the breath, the monitoring can be selectively switched off to avoid accidental inflation of the vest.

According to the invention, the at least one regulating valve is formed by a bypass valve which can be transferred to an actuating position in which a line branching from a control volume of the time control unit is connected to an additional volume.

On the other hand, the check valve interrupts the connection between the line and the

Additional volume in a normal position, in which the check valve via a with a

Outlet side of the inflation valve connected control line can be transferred. In this way, a time window, after its elapse and no breathing activity of the diver emergency measures are initiated, can be selectively increased by a larger total volume is formed by switching the additional volume to the control volume, resulting in a later reaching a trigger pressure for transfer of the emergency valve in the emergency position ,

According to a further advantageous embodiment of the invention, a pretesting valve is provided with an actuating element, wherein the pretesting valve in an actuated position connects a control line of the control valve with the compressed air cylinder, so that the control valve activates the control device. By providing the pre-check valve, a proper function of the control device can thus already be checked on the water surface prior to a dive. Otherwise it will be through the

Control valve made only one activation of the control device, if one corresponding ambient water pressure is reached. By pressurizing a control line of the control valve, this pressure control is now bridged and thus the time control unit of the control device already at the water surface with the

Compressed air cylinder connected. In the consequence can be checked then whether the

Time control unit of the control device and subsequently the emergency valve for emergency inflation of the vest to work properly. In combination with the provision of an aforementioned reset valve in the region of the inflation valve, this checking function can then be interrupted again by depressurizing an inlet to the control valve through the reset valve. An actuation element of the pretest valve is in this case preferably designed as a pushbutton, but can also be used within the scope of the invention

be realized elsewhere.

It also results in ways to combine individual features, even if they emerge from the claims, the following description of an embodiment or directly from the drawings. The reference of the claims to the drawings by use of reference numerals is not intended to limit the scope of the claims. Further, advantageous embodiments of the invention will become apparent from the following description of a preferred embodiment of the invention, which refers to the figures shown in the drawings. It shows:

From Figure 1 is a block diagram of a diving equipment according to a preferred embodiment of the invention. This diving equipment includes one here

Compressed-air cylinder 1, which supplies compressed air to a breathing apparatus, not shown here, so that a diver can be supplied with breathing air under water. Furthermore, an inflatable vest 2 is provided, which is provided with a - also not shown here - bubble, which can either be inflated by the compressed air cylinder 1 with compressed air or discharged from the air. According to that

Feeding or deflation of air can be compensated for a buoyancy of the diver on the vest 2 by a rise and by discharging air, a drop is represented by supplying a corresponding amount of air.

In a normal operation, the supply and discharge of air into the vest 2 is here controlled by intermediate valves in the form of an inflation valve 3 and a drain valve 4, which can be actuated respectively via an associated actuator 5 and 6 by the diver, said adjusting elements. 5 and 6 in the present case are each designed as push buttons. Both the inflation valve 3 and the drain valve 4 are designed as 2/2-way valves and are biased via an associated spring in the basic position shown here, from which they can be moved by the respective associated actuator 5 and 6 in an operating position. The inflation valve 3 connects in this operating position then the compressed air cylinder 1 with the vest 2, so that the vest 2 is inflated by supplying compressed air. Upon actuation of the actuating element 6 and transfer of the drain valve 4 in the operating position, the vest 2, however, is connected to a mouthpiece 7, via which compressed air from the vest 2 escape into the environment and thus a discharge of compressed air from the vest 2 can be displayed. In this case, however, a manual filling of the vest 2 can be made in an individual case via the mouthpiece 7. By appropriate actuation of the two valves 3 and 4, the diver can balance his buoyancy according to the filling or emptying of the vest 2. Furthermore, the diving equipment according to the invention has a control device 8, by which an absence of a breathing activity of the diver detected on the breathing apparatus and in an emergency operation inflation of the vest 2 can be forced, so that the diver is due to the inflated back to the water surface. For this purpose, the control device has an emergency valve 9, which in the present case is also designed as a 2/2-way valve and in an operating position, the compressed air cylinder 1 connects directly to the vest 2, so that an inflation of the vest 2 takes place. In the present illustrated basic position of the emergency valve 9, this connection is interrupted but, the emergency valve 9 by an associated spring element and by

Pressurization is biased by a control line 10 in this basic position. The control line 10 is in this case by a pressure port 1 1 with the current

supplied surrounding water pressure. Contrary to the spring element and the control line 10, the emergency valve 9 can be moved and held by corresponding pressure in two further control lines 12 and 13 in the operating position, wherein the control line 12 is in communication with a time control unit 14, while the control line 13 to the drain side of the emergency valve 9 and the supply to the vest 2 is connected. To move the emergency valve 9 in the operating position so a pressure in the control line 12 must exceed a pressure in the control line 10 and a pressure caused by the spring element. If the emergency valve 9 is then moved once into the actuating position, it is held by the control line 13 due to the then prevailing pressure in this position.

In the absence of breathing activity of the diver over a defined period of time, the control unit 12 is acted upon by the time control unit 14 with a pressure suitable for opening the emergency valve 9. This time control unit 14 comprises a control volume 15, which is continuously filled from the activation of the control device 8 via a filler panel 16 with pressurized air, wherein the control volume 15 is connected to the control line 12 of the emergency valve 9. From reaching a certain pressure in the

Control volume 15 while an operating pressure for moving the emergency valve 9 is reached in the operating position. Expiration of the control volume 15 is also a

Emptying valve 17 is provided, which is designed as a 2/2-way valve and at

Respiratory activity of the diver and a concomitant pressure drop is moved in the connected to the compressed air cylinder 1 line system from the illustrated basic position into an actuating position. In the operating position, the control volume 15 then emptied. In this case, according to the choice of a suitable volume of the

Control volume 15 and throttling on the filler panel 16 a time range are defined, after its expiry an emergency operation is initiated by the control device 8. However, this time range can be selectively extended by an additional volume 18 is switched to the control volume 15. For this purpose, a line 19 branches off on the outlet side of the control volume 15, which is connectable via an intermediate bypass valve 20 with the additional volume 18. This bypass valve 20 is designed as a 2/2-way valve, wherein in the illustrated basic position of the bypass valve 20, the line 19 is separated from the additional volume 18. The bypass valve 20 can now be selectively moved via an actuating element 21, in the present case in the form of a push button, into an actuating position, in which the line 19 and the additional volume 18 are connected to each other, so that fluid can flow into the additional volume 18. As a result, the volume between the filler panel 16 and the emptying valve 17 increases and thus also the actuating pressure for shifting the emergency valve 9 to the actuating position is reached later. To reset the bypass valve 20, a control line 22 is provided, which is connected to a drain side of the inflation valve 3, so that a transfer of the bypass valve 20 is carried out in the additional volume 18 separating from the line 19 basic position as soon as the inflation valve 3 is actuated.

To activate the control device 8, the timing control unit 14 is preceded by a control valve 23, which activates the control device 8 as a function of the currently surrounding water pressure. For this purpose, the control valve 23 is connected on the one hand via a control line 24 in normal operation with the pressure port 11 and is thus acted upon via this control line 24 with the surrounding water pressure and is connected to another via a different control line 25 with a reference volume 26, in which a Reference pressure, preferably the atmospheric pressure, prevails. The present as a 2/2-way valve designed control valve 23 separates the underlying time control unit 14 in the illustrated basic position of an inlet, the control valve 23 but then in an operating position this inlet with the

Time control unit 14 connects as soon as the surrounding water pressure the pressure in

Reference volume 26 and has exceeded a pressure represented by a spring element of the control valve 23. In normal operation, the supply is with the compressed air cylinder 1 connected. Consequently, therefore, the control device 8 from reaching a defined

Water depth activated by the control valve 23.

However, the activation of the control device 8 and thus the

Respiratory monitoring function of the time control unit 14 are temporarily terminated by the connection between the filler panel 16 of the time control unit 14 and the control valve 23 via a check valve 27 is interrupted. This check valve 27 is arranged between the filler panel 16 and the control valve 23 and in the present case designed as a 2/2-way valve. In the illustrated basic position, the check valve 27 allows a flow of fluid from the control valve 23 to the filler panel 16 as soon as the surrounding water pressure has exceeded the above-described pressure threshold. By means of an actuating element 28 in the form of a push button, however, the check valve 27 can be selectively leads into an actuating position, in which a flow of fluid to the filler panel 16 is prevented and accordingly no monitoring of the breathing activities by the time control unit 14 takes place. A reset of the check valve 27 is performed via a control line 29, which, like the control line 22, is connected to a discharge side of the inflation valve 3. Accordingly, a transfer of the check valve 27 is performed in the control valve 23 and the filler panel 16 connecting the basic position as soon as the inflation valve 3 is actuated.

As a further special feature, the diving equipment also comprises a check valve 30 and reset valves 31 and 32, as well as a pre-check valve 33, the respective function of which will now be described with the aid of the further FIGS. 2 to 5. In the figures 2 to 5 substance flows in the form of compressed air are shown as thick arrows, mechanical couplings as thin arrows and signal flows as dashed arrows.

As can be seen here from Figure 1, the reset valve 31 is mechanically with the

Discharge valve 4 is coupled, so that an actuation of the drain valve 4 via the adjusting element 6 also leads to an actuation of the reset valve 31. However, this mechanical coupling is designed such that this coupling is effective only from a second half of a possible adjustment range of the actuating element 6. About the first half of

Gesamtstellbereichs of the actuating element 6 so only the drain valve 4 is actuated, and then from a second half of the control range then the reset valve 31 is moved with.

In the present case, the reset valve 31 is designed as a 2/2-way valve, wherein an inlet side of the Reset valve 31 branches off from the control line 12 of the emergency valve 9 and a drain side of the reset valve 31 leads to the vest 2. As will now be seen in combination with the functional diagram in Figure 2, can be reset by the reset valve 31 a

Zeitablaufprozedur the time control unit 14 can be achieved by the control line 12 of the emergency valve 9 is depressurized. Because in the operating position of the reset valve 31, this connects the control line 12 with a non-pressurized line to vest 2. By this pressure-less circuit of the control line 12 is thus simultaneously reset the time-out procedure in the time control unit 14, since the control volume 15 is emptied, and subsequently a Monitoring the respiratory activity of the diver restarts.

With a movement of the reset valve 31, a movement of the check valve 30 is also coupled, so that the check valve 30 is moved from a second half of the setting range of the actuating element 6 of the drain valve 4 in an actuating position. The check valve 30 is also designed as a 2/2-way valve and is presently arranged between the emergency valve 9 and the compressed air cylinder 1. In the illustrated basic position, the check valve 30 thereby allows a supply of compressed air, starting from the compressed air cylinder 1 to the emergency valve 9. However, the check valve 30 is now in the

Shifted operating position, the connection between the emergency valve 9 and the compressed air cylinder 1 is interrupted. The diver has so over the check valve 30, the possibility in the event of unwanted inflation of the vest 2 in emergency mode, which may occur, for example, with prolonged stopping of the breath, this unwanted

Inflate by appropriate actuation of the check valve 30 to interrupt. Because in this case an inflow to the emergency valve 9 is prevented, as well as from the

Functional scheme in Figure 3 shows.

FIG. 1 further shows that the further reset valve 32 is mechanically coupled to a movement of the inflation valve 3 when actuated via the adjusting element 5. This reset valve 32 is designed as a 3/2-way valve, which connects in the illustrated basic position, an inlet of the control valve 23 with the compressed air cylinder 1, upon reaching an actuating position by moving over the actuator 5, however, the inlet of the control valve 23 with a non-pressurized line Vest 2 connects. By this pressure-less switching of the supply to the control valve 23, an activation of the control device 8 is reset, since in this case, a branched off from the outlet side of the control valve 23 control line 34 of the control valve 23 is depressurized becomes. As a result, the control device 8 is activated by the control valve 23 only when the pressure applied to the control line 24 is higher than that in FIG

Reference volume 26 prevailing pressure and by the spring element of

Control valve 23 shown pressure. This reset function is also apparent from the functional diagram in FIG.

Finally, as a further special feature, as can be seen in FIG. 1, a pretesting valve 33 is provided, which can be manually transferred via an actuating element 35 from the illustrated basic position into an actuating position. This pre-test valve 33 is designed here as a 3/2-way valve and connects in the basic position the

Pressure port 11 with the control line 24 of the control valve 23. When manually operated on the actuator 35 and upon reaching the operating position is the

Control line 24 of the control valve 23, however, connected to the compressed air cylinder 1, which causes a direct transfer of the control valve 23 in the operating position.

Accordingly, an activation of the control device 8 and this regardless of a surrounding water pressure, so that the pre-check valve 33, a check for proper operation of the control device 8 also above the

Water surface and can be performed independently of the otherwise necessary for activation criteria. As can be seen in combination with the functional diagram of FIG. 5, this preliminary function test can then be carried out after releasing the

Actuator 35 and reset by pressing the reset valve 32 via the actuator 5. Otherwise, the control valve 23 would always be kept in the operating position due to the branching off from its outlet side control line 34.

In the present case, couplings of the check valve 30 and the reset valve 31 with the drain valve 4 and a coupling of the reset valve 32 with the inflation valve 3 are shown mechanically. However, within the meaning of the invention, a hydraulic,

pneumatic or electrical coupling conceivable. Resetting the emergency valve 9, the Bypassventiis 20, the check valve 27 and also the control valve 23 is pneumatically solved in the present case in each case via control lines, but within the scope of the invention this can also mechanically, hydraulically or electrically accomplished according to a detected at another location pressure become. By means of the inventive design of a diving equipment, it is thus possible to easily influence functions of the control device 8 of the diving equipment. In this case, such an operation can also be performed by a dive partner, for example a diving instructor.
