Underwater vehicle with a lockable flap

Description

[0001] The invention relates to an underwater vehicle with a flap and with a locking device for locking this flap.

[0002] DE 20 2006 004 805 U1 discloses a submarine in which boat components arranged in a space between the pressure hull and the outer skin are reliably protected by a cover, but at the same time easy and quick access is possible.

[0003] DE 10 2007 041 724 A1 discloses a container that can be carried on the outside of a submarine.

[0004] US 3,051,280 A an outward opening aircraft door.

[0005] CN 201 834 177 U discloses a quick-opening and closing fireproof and watertight hatch cover.

[0006] The object of the invention is to provide an underwater vehicle having the features of the preamble of claim 1, in which the locking device locks the associated flap more securely and can be operated more easily than in known underwater vehicles.

[0007] This object is achieved by an underwater vehicle having the features specified in claim 1. Advantageous further developments emerge from the subclaims, the following description, and the drawings.

[0008] The underwater vehicle according to the invention comprises an outer shell, at least one flap and a locking device for each flap.

[0009] Each locking device includes two locking bodies, one actuating element and one transmission means per locking body.

[0010] Each transmission means is mechanically connected to the actuating element and to the associated locking body.

[0011] The outer shell encloses an interior area. The outer shell separates this interior area from an exterior area outside the outer shell. The or each flap is mechanically connected to the outer shell and can be moved back and forth relative to the outer shell between a closed position and an open position.

[0012] When the flap is closed, each locking element and transmission element are located inside. The actuating element for this flap can be accessed from outside when the flap is closed.

[0013] Each locking element can be moved back and forth between a locking position and a release position. The actuating element can be moved relative to the associated flap and thus actuated from the outside. Each transmission element connected to the actuating element transmits a movement of the actuating element to the associated locking element, thereby causing the locking element to move from one position to the other. This resulting movement of several locking elements locks or unlocks the flap.

[0014] The underwater vehicle according to the invention comprises an outer hull and at least one flap. The or each flap is movably embedded in the outer hull and can be opened and closed again. When the flap is open, access to the interior is possible from the outside. For example, with the flap open, it is possible to move objects into an interior chamber or to remove objects from this chamber. When the flap is closed, the flap protects the interior, for example the chamber, from environmental influences. In particular, it is possible for the flap to be designed such that the interior is protected from the ingress of water. Objects in the chamber cannot be washed away. It is also possible for a watertight container to be located in the chamber, at least temporarily, which in turn holds objects.The closed and locked flap prevents this container from floating away, becoming damaged, opening on its own, or being removed without authorization.

[0015] The locking device is capable of locking the associated closed hatch, thus preventing the closed and locked hatch from opening accidentally. Without the locking device, this could happen, particularly if the underwater vehicle rolls back and forth in the water or otherwise moves back and forth relative to the surrounding water, or is subjected to a sudden load. The locked hatch can be unlocked from the outside.

[0016] The or each locking device comprises at least two locking bodies. These locking bodies are spatially spaced from one another. This locks the flap at at least two points, with a gap between these points. Compared to a single locking body per flap, the use of at least two locking bodies further prevents the risk of the closed and locked flap opening unintentionally. Even if one locking body is not in a locking position due to a fault, the or at least one other locking body will still lock the flap. If the closed flap is bent in the opening direction, the resulting gap between the flap and the outer shell is smaller with at least two locking bodies than with just a single locking body.

[0017] According to the solution, each locking body for the flap or a flap is connected to the same actuating element via a transmission means. By actuating this single actuating element, all locking bodies for this flap can be moved into the locked position or into the release position with one move, virtually with a single movement. It is not necessary for a user to operate multiple actuating elements one after the other to lock or unlock the same flap. This design saves time. This design is particularly advantageous when the flap or a flap needs to be locked or unlocked while the underwater vehicle is submerged. This process usually requires a diver to descend to the underwater vehicle and work underwater. Visibility underwater is often significantly poorer than above water or on land, and a diver can only stay underwater for a limited period of time.For both reasons, it is advantageous to have only a single actuator to operate. The diver only needs to locate and operate a single actuator to open the flap or a hatch.

[0018] According to the solution, the actuating element of the or each locking device is accessible from the outside. This means that the locking device can be actuated from the outside. Therefore, it is not necessary for a person, such as a diver, to enter the interior of the underwater vehicle to access the interior, for example, to move objects into or out of the chamber. The underwater vehicle does not necessarily need to have an interior area in which a person can be present.

[0019] According to the solution, each locking body and each transmission means are arranged entirely within the interior. Thus, the outer shell and the closed flap protect the locking bodies and transmission means from environmental influences, in particular from the surrounding water. Furthermore, no locking body or transmission means impairs the hydrodynamic properties of the underwater vehicle when traveling above or below water, which could be the case if a locking body or transmission means were arranged at least partially outside the interior. In particular, no locking body or transmission means can cause turbulence in the water.

[0020] Preferably, the actuation of an actuating element causes the at least two locking bodies of this locking device to be moved simultaneously from one position to the other position.

[0021] According to the invention, the actuating element comprises an actuating rotation axis. This actuating rotation axis extends through the associated flap. A user can rotate this actuating rotation axis from the outside and thereby actuate the transmission means and move the at least two locking bodies connected to this actuating element. The actuating rotation axis of the actuating element is mechanically connected internally to the two transmission means. Each transmission means connected to this actuating element can be guided entirely internally and along the flap. It is not necessary to guide the transmission means along an edge of the flap.

[0022] Preferably, at least one recess is formed in the or each flap. Or at least one handle is attached to the flap. With the aid of this recess or handle, a user, for example a diver, can move the unlocked flap relative to the outer shell and thereby open it. It is not necessary for the user to carry a tool to move the unlocked flap.

[0023] Preferably, the or each flap, when closed, is flush with the outer hull. As a result, the flap does not impair the hydrodynamic properties of the underwater vehicle or its signature, i.e., its detectability in a radar or sonar image. Preferably, the end piece of the actuating element, which still points outwards, is also flush with the outer hull and does not protrude. This design further improves the hydrodynamic properties of the underwater vehicle in the water. Preferably, a recess for an Allen key is recessed into the actuating rotation axis, said recess being accessible from the outside. A user can rotate the actuating rotation axis using a commercially available Allen key, thereby actuating the actuating element and locking or unlocking the flap. No special tool is required for actuation.

[0024] In one embodiment, the locking body or at least one locking body comprises a locking element and a locking body rotation axis. The locking element is fixedly mounted on the locking body rotation axis. The locking body rotation axis is rotatable and mounted from the inside on the associated flap. In the locking position, the locking element engages at least partially under the outer shell, so that the outer shell is located between the locking element and the outer region. In the release position, the locking element does not overlap with the outer shell. The transmission means can move the locking body rotation axis and thus the locking element. It is not necessary for the transmission means to be directly connected to the locking element.

[0025] In one embodiment, the or at least one transmission means comprises two lever arms and a connecting means between these two lever arms. The first lever arm is connected to the actuating element, in the case of a rotatable actuating element, in a rotationally fixed manner to the actuating axis of rotation, and the other lever arm is connected to the locking body axis of rotation. Actuation of the actuating element causes the actuating axis of rotation to be rotated, the first lever arm on the rotated actuating axis of rotation moves the connecting means, and the moved connecting means rotates the locking body axis of rotation. Or the first lever arm connected to the actuating element is moved in another way, moving the connecting means. In both embodiments, movement of the connecting means causes the second lever arm to be moved and the locking element to be rotated from one position to the other position.

[0026] In one embodiment, the connecting means extends along a longitudinal axis and has, for example, the shape of a rod. The length of this connecting means can preferably be adjusted, for example, so that each locking body can be moved with sufficient ease while also securely locking and releasing the flap. The ability to adjust the length makes it easier to adapt the locking device to different environmental conditions, for example, to different water temperatures or desired diving depths.

[0027] According to the invention, an opening is let into the flap or a flap. A user can reach the actuating element through this opening using a suitable tool. In a preferred embodiment, this opening is automatically closed as long as the user does not actuate the actuating element. A spring element tends to move a plunger into a closed position. In this closed position, the plunger closes the opening. The plunger thus prevents water from penetrating through the opening into the interior area enclosed by the outer shell. Preferably, the spring force exerted by the spring element is large enough to allow the plunger to maintain its closed position down to a certain diving depth of the underwater vehicle. Thanks to the spring element, the plunger automatically closes the opening without user intervention being required. Preferably, the spring is supported on the actuating element.

[0028] The plunger can be moved against the spring force of this spring element to release the opening and to allow the actuating element to be moved through the opening. Preferably, the plunger can be moved from the outside against the spring force by inserting a suitable tool through the opening and pressing it against the plunger. This design allows a user, such as a diver, to insert a tool into the opening and first move the plunger from the closed position against the spring force, and then actuate the actuating element without first having to withdraw the tool from the opening.

[0029] According to the invention, this plunger additionally provides a valve. This valve compensates for any pressure difference between the interior and exterior areas, at least when the plunger is moved away from the opening against the spring force. This design, in particular, prevents the pressure difference from causing the unlocked flap to open abruptly when the pressure inside is significantly higher.

[0030] In one embodiment, the actuating element or at least one actuating element is rotatably mounted. Rotation of the actuating element causes each locking body of the associated locking device to be moved from one position to the other. It is also possible for the actuating element or at least one actuating element to be displaceably mounted, and displacement of the actuating element causes the associated locking body to be moved from one position to the other. In one embodiment, each transmission means has a lever arm. The at least two lever arms are connected in a rotationally fixed manner to the rotatable actuating element.

[0031] The design with the plunger can be combined with the design with the rotatably mounted actuating element. Preferably, a user moves the plunger away from the opening by inserting a tool into the opening and then actuates the actuating element by rotating the inserted tool.

[0032] In one embodiment, the rotatably mounted actuating element is connected to the plunger in a rotationally fixed manner. The plunger is mechanically connected to each transmission means of this locking device. Rotation of the actuating element therefore causes the plunger to rotate as well. Each transmission means transmits the rotation of the plunger to the associated locking body. This embodiment enables a particularly compact design, in particular because the axis of rotation of the actuating element can coincide with the axis of rotation of the plunger and because the plunger has two functions: firstly, to seal the opening and secondly, to transmit the rotation of the actuating element to the transmission means. Two different components are therefore not required. In another embodiment, the actuating element can rotate relative to the plunger.

[0033] In one embodiment, the or at least one locking device additionally has a locking unit which is movable between a locking position and a release position.

[0034] This locking unit prevents the actuating element of this locking device from moving unintentionally in the locked position, thus rendering the associated flap unlocked. In particular, this locking unit prevents the actuating element from moving without user intervention in the locked position in such a way that the locking bodies of this locking device are moved into the release position, or that the movement of a locking body or a transmission means causes a movement of the actuating element and thus a movement of each locking body into the release position.

[0035] The design with the locking unit can be combined with the design that provides a plunger and a spring element. In one embodiment of this combination, the same spring element performs two functions simultaneously: Firstly, the spring element holds the plunger in the closed position. Secondly, the spring element holds the locking unit for the actuating element in the locked position. This design enables a particularly compact construction and saves space compared to a design in which two different elements hold the plunger in the closed position and the locking unit in the locked position. When the plunger is moved against the spring force, the locking unit is simultaneously moved into the release position.

[0036] In a further embodiment of the invention, at least two flaps are rotatably embedded in the outer hull. Preferably, each flap can be opened and closed independently of the or any other flap, and locked and unlocked in the closed position. This makes it easier to gain access to the interior from different directions. Optionally, only one flap can be opened, leaving the or any other flap closed and locked, or both or at least two flaps can be opened and unlocked. This makes it possible to create either a smaller opening or a larger opening to the interior. Each flap is assigned a locking device, each having at least two locking bodies, two transmission means, and one actuating element. The underwater vehicle thus comprises a total of at least two actuating elements, at least four locking bodies, and at least four transmission means.

[0037] The vessel with the flap and locking device can be a surface vessel or an underwater vessel and can have its own propulsion or be towed through the water by another vessel. The vessel can be manned or unmanned. The outer hull can also form a pressure hull of the underwater vessel or enclose the pressure hull, with the pressure hull being located in the interior. The outer hull can also enclose only part of the pressure hull. It is also possible for the underwater vessel to be unmanned and not have a pressure hull enclosing an interior area for crew members. If the underwater vessel is in a floating position above water, the flap can be located below or above the waterline.

[0038] The underwater vehicle according to the invention is explained in more detail below using an embodiment shown in the drawings. Fig. 1 in a viewing direction from the outside, the outer shell with both flaps in the closed position; Fig. 2 in a cross-sectional view of the outer shell with the left flap open and the right flap closed; Fig. 3 in a viewing direction from the inside, the outer shell with both flaps in the closed position, the left flap locked and the right flap unlocked; Fig. 4 in a viewing direction from the inside a detailed view of the arrangement of Fig. 3 with the two rear locking claws; Fig. 5 in a viewing direction from the inside, the left flap in the locked position; Fig. 6 in a viewing direction from the inside, the right flap in the unlocked state; Fig. 7in a detailed view from the inside the right central axis of rotation for the right flap; Fig. 8 in a detailed view from the inside and parallel to the plane of the right flap, the right rear locking claw; Fig. 9 in a cross-sectional view approximately parallel to the plane of the right flap, the right central axis of rotation for the right flap.

[0039] In the exemplary embodiment, the invention is used to lock two flaps, wherein these two flaps are rotatably inserted into the outer hull of an underwater vehicle with a pressure hull. When the two flaps are opened, they provide access to a chamber in the interior of the outer hull. Preferably, the pressure hull of the underwater vehicle is arranged in the interior of the outer hull, and this chamber is located between the outer hull and the interior. It is also possible for the outer hull to only surround an upper part of the pressure hull, for example by being placed on top of the pressure hull. When the two flaps are closed, they are flush with the rest of the outer hull of the underwater vehicle.

[0040] In the illustrated embodiment, each flap can be opened and closed independently of the other flap. Furthermore, each closed flap can be moved independently of the other flap into a locked or unlocked state. The flap can only be opened in the unlocked state. Moving the closed flap into the locked state prevents it from accidentally opening on its own. In the illustrated embodiment, both flaps are made of fiberglass-reinforced plastic to keep them lightweight and rotate relatively easily.

[0041] A user can move each door from the locked to the unlocked state and then open the unlocked door to insert or remove at least one object from the chamber. It is desirable that the door can be unlocked and opened even when the underwater vehicle is fully submerged, for example, by a diver.

[0042] Fig. 1 shows the two flaps in the closed position, viewed from the outside. The direction of travel FR of the underwater vehicle is shown in Fig. 1 from bottom to top. A left flap 1.1 and a right flap 1.2 are inserted into the outer shell 2.

[0043] Fig. 2 shows a cross-sectional view of the outer shell with the left flap 1.1 open and the right flap closed. The planes of the two flaps 1.1 and 1.2 are perpendicular to the plane of the drawing of Fig. 2. The direction of travel FR is perpendicular to the plane of the drawing and points away from the observer. In Fig. 2 a chamber K and several objects G.1, G.2, ... can be seen in this chamber K, whereby the flaps 1.1 and 1.2 can close this chamber K. Fig. 3 to Fig. 7 show the two flaps 1.1 and 1.2 in the closed state from the inside. The plane of the two flaps 1.1 and 1.2 lie in the drawing planes of Fig. 3 to Fig. 7 The observer looks from inside the outer shell 2 at the two closed flaps 1.1 and 1.2.

[0044] A reinforcement element 5.1 is mounted on the inside of the left flap 1.1, and a reinforcement element 5.2 is mounted on the inside of the right flap 1.2. The left flap 1.1 can rotate about a rotation axis 15.1 relative to the outer shell 2, and the right flap 1.2 can rotate about a rotation axis 15.2. The left rotation axis 15.1 is mounted on a left cross member 7.1, which is fastened on the inside to the outer shell 2 and extends approximately parallel to the direction of travel FR, and the right rotation axis 15.2 is mounted on a right cross member 7.2. When both flaps 1.1 and 1.2 are closed, the two flaps 1.1 and 1.2 are located between the two rotation axes 15.1 and 15.2. Between the two flaps 1.1 and 1.2, three oval gripping openings 3.1, 3.2, and 3.3 are formed, created by corresponding recesses in the free (inner) edges of the two flaps 1.1 and 1.2. A user can reach into such a gripping opening from the outside to open a closed and unlocked flap 1.1 or 1.2.

[0045] A receiving element 8 is mounted on the inside of the outer shell 2. This element receives the reinforcement element 5.1 when the left flap 1.1 is closed, and the reinforcement element 5.2 when the right flap 1.2 is closed. A front left locking claw 16.1 and a rear left locking claw 6.1 are mounted on the left flap 1.1 near the rotation axis 15.1 - as seen in the direction of travel FR. The front left locking claw 16.1 is held to the flap 1.1 with a bracket 26.1, and the rear left locking claw 6.1 with a bracket 36.1 (see Fig. 1). Fig. 3 The heads of three screws of this bracket 26.1, 36.1 are in Fig. 1 to see the lower ends of these screws in Fig. 3. When the left flap 1.1 is closed, these two locking claws 16.1 and 6.1 engage the receiving element 8. Accordingly, a front right locking claw 16.2 and a rear right locking claw 6.2 are mounted on the right flap 1.2 near the rotation axis 15.2, each with a holder 26.2, 36.2.

[0046] A left central pivot axis 4.1 extends through the left flap 1.1. This left central pivot axis 4.1 is positioned approximately midway between the front end and the rear end of the left flap 1.1—as viewed in the direction of travel FR—close to the free edge of the left flap 1.1 and close to the gripping opening 3.2. Similarly, a right central pivot axis 4.2 extends through the right flap 1.1. A user can externally place a tool onto the left central pivot axis 4.1 and use this tool to rotate the left central pivot axis 4.1 in either direction. Rotating the left central pivot axis 4.1 moves the left flap 1.1 from the locked to the unlocked state, or vice versa, from the unlocked to the locked state. How this is achieved is described below.

[0047] In Fig. 1a hexagonal opening 0.1 can be seen on the outside of the left pivot axis 4.1. A user can place an Allen key onto this opening 0.1 from the outside and press the key down to then rotate the left pivot axis 4.1 relative to the left flap 1.1. This is described in detail below. Similarly, a user can rotate the right pivot axis 4.2 relative to the right flap 1.2 by placing the Allen key onto the opening Ö.2 at the top of the right pivot axis 4.2. The circular surface at the end of the central pivot axes 4.1, 4.2 is flush with the flap 1.1, 1.2. The heads of the screws that fasten the brackets 13.1, 13.2 to the flap 1.1, 1.2 are also flush with the flap 1.1, 1.2.

[0048] Fig. 3shows both flaps 1.1 and 1.2 in the closed state. The viewing direction is that of an observer who is located inside the outer shell 2 and looks vertically upwards at the closed flaps 1.1, 1.2. The left flap 1.1 (in Fig. 3 above) is locked, the right flap 1.2 (in Fig. 3 bottom) is not locked. The left flap 1.1 can be locked using a front left locking claw 19.1 and a rear left locking claw 9.1. Similarly, the right flap 1.2 can be locked using a front right locking claw 19.2 and a rear right locking claw 9.2. When the left flap 1.1 is closed, a front segment of the rear left locking claw 9.1 is located below a counter element 30.1, see. Fig. 4 , and a front segment of the front left locking claw 19.1 below a Fig. 4not shown counter element 40.1. Accordingly, a front segment of the rear right locking claw 9.2 is located below a counter element 30.2 and a front segment of the front right locking claw 19.2 is located below a counter element 40.2. The two counter elements 30.1 and 30.2 are firmly mounted on a reinforcement 29. This reinforcement 29 is mounted inside the outer shell 2, extends perpendicular to the direction of travel FR and is located between the closed flaps 1.1, 1.2 and the counter elements 30.1 and 30.2. The other two counter elements are firmly mounted on a reinforcement 39.

[0049] In Fig. 3 and Fig. 4the left locking claws 19.1 and 9.1 are in a locked position and the right locking claws 19.2 and 9.2 are in a released position. When the two locking claws 19.1 and 9.1 on the left flap 1.1 are in the locked position, the left flap 1.1 is locked. Three edges of the left flap 1.1 are connected to the surrounding outer shell 2, namely one edge by the pivot axis 15.1 and two edges by one locking claw each, 19.1 and 9.1. If these two locking claws 19.1 and 9.1 are in the released position, the left flap 1.1 can be opened. The same applies to the right flap 1.2. The rear left locking claw 9.1 is fixedly mounted on a pivot 11.1. This pivot 11.1 is rotatably mounted on the left flap 1.1 by means of a bracket 14.1. The pivot 11.1 and an approximately triangular plate 17.1 of the bracket 14.1 are attached to the inside of the left flap 1.1.Three screws are passed through the left flap 1.1 and hold the plate 17.1 of the bracket 14.1 to the inside of the left flap 1.1. In . Fig. 1 the three heads of these three screws can be seen, which are also flush with the outer shell 2.

[0050] If the rotation axis 11.1 is rotated in one direction (in Fig. 3 and Fig. 4 If the rotation axis 11.1 is rotated in the opposite direction (clockwise), the rear left locking claw 9.1 is moved from the locked position to the released position when the left flap 1.1 is closed. The same applies to the other three locking claws 19.1, 9.2, and 19.2.

[0051] By rotating the left central pivot axis 4.1 with the aid of a tool, a user transfers the left flap 1.1 from the locked state to the unlocked state or vice versa. This rotation of the central pivot axis 4.1 causes both locking claws 19.1 and 9.1 to be moved simultaneously from the locked position to the release position or simultaneously from the release position to the locked position. One transmission means per locking claw 19.1 and 9.1 synchronously transfers the rotation of the left central pivot axis 4.1 to both left locking claws 19.1 and 9.1. Correspondingly, one transmission means per locking claw 19.2 and 9.2 transfers the rotation of the right central pivot axis 4.2 synchronously to both right locking claws 19.2 and 9.2.

[0052] The transmission means for the rear right locking claw 9.2 is described below with reference to Fig. 3 , Fig. 4 , Fig. 6, Fig. 7 , Fig. 8 and Fig. 9 described. Fig. 7 shows in a detailed view from the inside the right central axis of rotation 4.2 for the right flap 1.2, namely the area A2 of Fig. 6 . Fig. 8 shows the right rear locking claw 9.2 in a detailed view from the inside and parallel to the plane of the right flap 1.2. Fig. 9 shows in a detailed view from the outside and parallel to the plane of the right flap 1.2 the right central axis of rotation 4.2 for the right flap 1.2.

[0053] A right central bracket 13.2 holds the right central pivot axis 4.2 rotatably on the right flap 1.2. Several screws 53.1, 53.2, ... are passed through the right flap, see. Fig. 9 A cross member 18.2 of the central right bracket 13.2 is mounted to the right flap 1.2 using screws 53.1, 53.2, ... Fig. 1 and in Fig. 9 the heads of these screws 53.1, 53.2, ... can be seen.

[0054] The pivot axis 4.2 passes through a sleeve 58.2 of the bracket 13.2 and can be rotated relative to the sleeve 58.2 about its own central axis. This sleeve 58.2 is embedded in the right flap 1.2 and is firmly connected internally to the cross member 18.2. A disk 60.2 is permanently mounted on the pivot axis 4.2. This disk 60.2 is accommodated in a corresponding recess in the cross member 18.2 and allows the pivot axis 4.2 to rotate, but prevents the pivot axis 4.2 from being displaced relative to the cross member 18.2 parallel to the central axis of the pivot axis 4.2.

[0055] In the following, with reference to Fig. 7 and Fig. 9Two different embodiments are described, in which the rotational axis 4.2 is mechanically connected to the rod 10.2. In the first embodiment, two lever arms 32.2 and 42.2 are pivotally connected to two holding elements 62.a and 62.b. These two holding elements 62.a and 62.b are rigidly connected to a plunger 55.2, offset by 180° from each other (see FIG. Fig. 7 and Fig. 9 The punch 55.2 is connected in a rotationally fixed manner to the right central axis of rotation 4.2. In the second embodiment, the two lever arms 32.2 and 42.2 are connected in a rotationally fixed manner to the axis of rotation 4.2. The two holding elements 62.a and 62.b are fixedly connected to the axis of rotation 4.2. The punch 55.2 can not only move linearly relative to the axis of rotation 4.2, but also rotate about the common central axis. Furthermore, the punch 55.2 can move relative to the two holding elements 62.a and 62.b along its own central axis. Fig. 9the stamp 55.2, the holding elements 62.a and 62.b and the lever arm 32.2 can be seen in detail.

[0056] In both embodiments, this lever arm 32.2 is connected to a connecting element 31.2 via a joint 28.2, cf. Fig. 7 and Fig. 9 A screw 61.2 connects the lever arm 32.2 to the joint 28.2 and to the connecting element 32. The connecting element 31.2 is connected to a rod 10.2. In one embodiment, the distance between the connecting element 31.2 and the rod 10.2 can be adjusted using two screws. In one embodiment, the length of the rod 10.2 can be adjusted.

[0057] In addition, Fig. 7 and Fig. 9a stop element 23.2 with a circular plate can be seen. This stop element 23.2 is firmly connected to the cross member 18.2 by means of two screws 59.a, 59.b and prevents any rotation of the rotation axis 4.2 and thus of the lever arm 32.2 relative to the flap 1.2. In one embodiment, this stop element 23.2 also prevents any rotation of the piston 55.2. As shown in Fig. 9 As can be seen, two locking pins 57.a and 57.b are mounted on a locking washer 56.2. This locking washer 56.2 is connected in a rotationally fixed manner to the rotation axis 4.2 and, in one embodiment, also in a rotationally fixed manner to the punch 55.2. These two locking pins 57.a and 57.b engage in the Fig. 9In the situations shown, the two pins 59.a and 59.b engage in the two recesses, neither the rotational axis 4.2 nor the lever arm 32.2 can be rotated relative to the cross member 18.2 and thus relative to the flap 1.2, because the stop element 23.2 prevents this rotation. In one embodiment, the plunger 55.2 cannot be rotated either. The locking washer 56.2, the two locking pins 57.a and 57.b, and the stop element 23.2 with the two recesses thus belong to a locking device for the rotational axis 4.2.

[0058] The punch 55.2 engages from the inside into the hollow interior of the rotation axis 4.2 and can be moved relative to the rotation axis 4.2 along the common central axis. In the first embodiment, the two holding elements 62.a and 62.b can be moved together with the punch 55.2 relative to the rotation axis 4.2. In the second embodiment, the punch 55.2 can be moved linearly relative to the two holding elements 62.a and 62.b. In both embodiments, the stop element 23.2 limits the movement of the punch 55.2 away from the opening Ö.2. A compression spring 54.2 is supported on the rotation axis 4.2 (first embodiment) or on the two holding elements 62.a and 62.b (second embodiment) and strives to move the punch 55.2 away from the stop element 23.2 into the Fig. 9The upper end of the plunger 55.2 thus closes the hexagonal opening Ö.2 in the rotation axis 4.2 and thus prevents water from penetrating from the outside.

[0059] When the piston 55.2 is displaced linearly relative to the rotation axis 4.2 away from the opening Ö.2, the opening Ö.2 is opened. In one embodiment, the piston 55.2 is designed as a valve. When the piston 55.2 is displaced, the valve provided by the piston 55.2 compensates for a pressure difference between the interior area, for example, of the chamber closed by the flap 1.2, and the exterior area outside the flap 1.2. Such a pressure difference can occur, for example, when the underwater vehicle surfaces during a dive and an overpressure has developed in the chamber.

[0060] When the plunger 55.2 is moved away from the opening Ö.2, this movement also causes the plunger 55.2 to move the locking washer 56.2 away from the opening Ö.2. This, in turn, causes the two locking pins 57.a and 57.b to no longer engage in the two recesses of the stop element 23.2, thus placing the locking unit for the rotary axis 4.2 in a release position.

[0061] The rod 10.2 is connected to another connecting element 25.2, see. Fig. 8This connecting element 25.2 is connected to a lever arm 12.2 via a joint 27.2. The lever arm 12.2 is firmly connected to the locking claw 9.2. The lever arm 12.2 and the locking claw 9.2 are rotatably mounted on a pivot 11.2. An approximately triangular plate 17.2 of a bracket 14.2 is non-rotatably mounted to the right-hand flap 1.2 by means of three screws, whereby these three screws pass through the right-hand flap 1.2 (see Fig. Fig. 8 The bracket 14.2 holds the pivot axis 11.2. The pivot axis 11.2 is guided through a sleeve that is firmly connected to the plate 17.2.

[0062] The transmission mechanism for the rear right locking claw 9.2 includes the lever arms 32.2 and 12.2, the connecting elements 31.2 and 25.2, and the rigid rod 10.2. The three other locking claws 19.2, 9.1, and 19.1 have corresponding transmission mechanisms.

[0063] The following is an example and with reference to Fig. 9 Describes how the right flap 1.2 is opened. A user places an Allen key from the outside onto the hexagonal opening Ö.2 in the rotary axis 4.2. First, the locking of the rotary axis 4.2 is released. To do this, the user presses the Allen key, thereby moving the plunger 55.2 against the force of the spring 54.2 toward the stop element 23.2.

[0064] The punch 55.2 is thereby displaced relative to the rotation axis 4.2 along the longitudinal axis of the rotation axis 4.2. Now the Allen key, and no longer the punch 55.2, closes the hexagonal opening Ö.2. The movement of the punch 55.2 causes the locking washer 56.2 with the two pins 57.a and 57.b to also be displaced away from the opening Ö.2 (in Fig. 9downwards) and thus the two pins 57.a and 57.b no longer engage in the two recesses in the stop element 23.2. This releases the locking of the rotation axis 4.2. The disc 60.2 continues to prevent the rotation axis 4.2 from being displaced relative to the cross member 18.2.

[0065] The user now turns the inserted Allen key. This rotates the rotation axis 4.2 relative to the sleeve 58.2 and thus also relative to the cross member 18.2 around its own central axis. In the first embodiment, the punch 55.2 is connected in a rotationally fixed manner to the rotation axis 4.2, and the holding elements 62.a, 62.b are firmly connected to the punch 55.2. The rotationally fixed punch 55.2 is rotated along with the rotation axis 4.2. This also rotates the holding elements 62.a and 62.b and thus the lever arms 32.2 and 42.2 (in Fig. 9(not shown) rotates. In the second embodiment, the rotation axis 4.2 is firmly connected to the two lever arms 32.2 and 42.2. A rotation of the rotation axis 42.2 is transmitted directly to the two lever arms 32.2 and 42.2.

[0066] In both embodiments, this rotation of the lever arms 32.2 and 42.2 is transmitted to the connecting elements 31.2 and 41.2 (in Fig. 9 not shown) and then onto the rods 10.2 and 20.2 (in Fig. 9 not shown) and thus transferred to the associated locking claws 9.2 and 19.2. The rotation unlocks the flap 1.2. The user then removes the Allen key. The compression spring 54.2 moves the plunger 55.2 back into the closing position, which is shown in Fig. 9 The user can rotate and open the unlocked flap 1.2 using the recesses 3.1, 3.2, and 3.3. Later, the user can close and lock the flap 1.2 again using the corresponding method.
