[0008] Title: Vehicle wall with an emergency exit hatch, and armored vehicle with such a vehicle wall

[0009] Description

[0010] The present invention relates to a vehicle body with the features of claim 1. Furthermore, the present invention relates to an armored vehicle with the features of the dependent claim.

[0011] Armored vehicles, especially armored tracked vehicles, are known from the prior art and are typically equipped in such a way as to provide the occupants with protection from gunfire and from mine / IED explosions (Improvised Explosive Device).

[0012] This protection is achieved primarily through armored vehicle walls. This results in a very high overall weight for armored vehicles. This high weight necessitates technical solutions that allow the occupants to exit the vehicle even if it rolls over, for example, due to gunfire or driver error.

[0013] It is known to create such an emergency exit option by equipping a vehicle wall with an emergency exit hatch. A vehicle wall with an emergency exit hatch is known, for example, from the patent applications DE 10 2021 126 174 Al and DE 10 2022 101 040 Al.

[0014] DE 10 2021 126 174 A1 discloses a separate lifting device for an emergency exit hatch. First, the lifting device must be positioned below the emergency exit hatch and attached to the vehicle wall. The emergency exit hatch can then be moved out of the vehicle wall by the lifting device. DE 10 2022 101 040 A1 proposes that the lifting device be designed as a hydraulic cylinder, a spindle lift, or a scissor lift.

[0015] DE 10 2022 101 040 A discloses an emergency exit hatch to which a rack is attached. When the vehicle is upside down, the emergency exit hatch can be pushed outwards over the vehicle floor by a drive wheel mounted inside the vehicle.

[0016] The invention is based on the objective of providing a way to quickly and reliably open an emergency exit hatch in a vehicle wall.

[0017] The invention solves this problem by means of a vehicle wall with the features of claim 1.

[0018] The proposed vehicle body for an armored vehicle has a first side that is associated with, or assigned to, the vehicle's interior. When the vehicle body is used as intended as part of an armored vehicle, the first side therefore faces the vehicle's interior. The side of the vehicle body opposite the first side is referred to below as the second side. When the vehicle body is used as intended as part of an armored vehicle, the second side faces the vehicle's exterior or its surroundings.

[0019] The proposed vehicle hull comprises a hull section in which an escape opening is formed. The proposed vehicle hull also comprises an emergency escape hatch, which can be arranged or is arranged in the escape opening. The hull section and the emergency escape hatch arranged in the escape opening together define the first and second sides of the vehicle hull. The vehicle hull and / or the emergency escape hatch may each be armored.

[0020] The vehicle wall also includes a lifting device located on the first side of the vehicle wall. The lifting device comprises two lifting units pivotally mounted on the wall section on opposite sides of the exit opening. The exit opening is thus located between the two lifting units. Since the lifting device is located on the first side of the vehicle wall, the two lifting units are also located on the first side of the vehicle wall, but on opposite sides of the exit opening. Preferably, the lifting device has two bearing parts attached to the wall section for mounting the lifting units. The bearing parts can, for example, be welded to the wall section. The lifting units are pivotable against the emergency exit hatch located in the exit opening in order to move the emergency exit hatch out of the exit opening.The lifting units allow the emergency exit hatch to be subjected to a compressive force. With a sufficiently high compressive force, the emergency exit hatch is moved out of the exit opening. Preferably, each lifting unit is pivotably mounted about an axis that is aligned parallel to the vehicle wall. The proposed design solves the underlying problem. To move the emergency exit hatch out of the exit opening, the two lifting units simply need to be pivoted sufficiently far towards the emergency exit hatch. Depending on the vehicle's position, the emergency exit hatch can then be pushed (on the second side) onto the surrounding section of the wall.Due to the arrangement of the lifting units (the lifting units are located on opposite sides of the escape opening), they can then be pivoted into a position in which they no longer obstruct the occupants' exit through the opening. A time-consuming, complete disassembly of the lifting units is not required. Likewise, there is no need to install the lifting units before removing the emergency escape hatch.

[0021] Compared to the lifting device proposed here, the gear mechanism from DE 10 2022 101 040 Al is more complex and prone to errors in operation. Furthermore, the gear requires a swivel unit that keeps the gear in position throughout its entire movement.

[0022] During the opening process of the emergency escape hatch, the mechanism pushes against the rack. A high number of gear rotations are required before the emergency escape hatch is finally open. This is particularly time-consuming when operated manually.

[0023] The lifting device from DE 10 2021 126 174 Al must first be positioned under the emergency escape hatch and secured there in a separate step in order to open the emergency escape hatch. Once the emergency escape hatch is open, the lifting device must be removed again. Only then can the occupants exit through the escape opening.

[0024] Within the context of the disclosure, the term "escape opening" refers to an opening in the wall section of the vehicle's body, the opening being dimensioned such that (adult) persons can pass through it. Within the context of the disclosure, the term "emergency escape hatch" refers to a plate-shaped closing element that can be arranged in the escape opening. If the emergency escape hatch is arranged in the escape opening, it closes the escape opening and forms part of the vehicle's body.

[0025] In some embodiments, the exit opening is rectangular. The rectangular exit opening can have two longer longitudinal sides and two shorter transverse sides. Preferably, the lifting units are arranged on the shorter transverse sides.

[0026] In some embodiments, the lifting units each have at least one lifting arm that can be pressed against the emergency exit hatch by pivoting the lifting unit. In particular, the lifting units each have two lifting arms that are non-rotatably connected to a common bearing axis. The bearing axes can be rotatably mounted by the aforementioned bearing components, with the lifting arms being pivoted by rotating the bearing axes.

[0027] Preferably, the vehicle body is armored. In these embodiments, both the body section and the emergency exit hatch each have at least one armor plate.

[0028] Preferably, the vehicle wall is a vehicle floor for an armored vehicle (vehicle floor wall). However, the vehicle wall can also be used elsewhere in an armored vehicle.

[0029] In some preferred embodiments, the lifting units are designed to pivot independently of one another. This reduces the force required to move the emergency escape hatch out of the escape opening. Alternatively, the lifting units can be mechanically linked in such a way that they can only pivot together. This reduces the time required to remove the emergency escape hatch.

[0030] In some preferred embodiments, the lifting units are pivotable into an opening pivot position in which the emergency escape hatch is moved so far out of the escape opening that it can be slid onto the wall section along a direction parallel to the wall section. Thus, the emergency escape hatch can be forcibly moved out of the escape opening by pivoting the lifting units to such an extent that it can be removed by sliding it onto the wall section.

[0031] In some preferred embodiments, each lifting unit is provided with a locking device. The locking devices secure the lifting units at least in the

[0032] The opening pivot position can be locked. The locking connections formed between the locking devices and the lifting units are designed in such a way that they prevent the emergency escape hatch from being lowered back into the escape opening. The locking devices have the advantage of facilitating the removal of the emergency escape hatch. In particular, the lifting units can initially be lowered into the opening by a single person.

[0033] The opening pivot position is brought into which the lifting units are then locked by the locking devices. Because the lifting units are now locked, the same person can slide the emergency exit hatch onto the wall section. Preferably, the locking devices each have at least one locking bolt, more preferably two locking bolts each. The locking bolts can be attached to the aforementioned bearing parts. Preferably, the locking bolts each have a movable locking pin that is pushed towards the associated lifting unit by a spring element. The lifting units each have a counter-locking structure, which is part of the locking device and into which the locking pin engages.

[0034] The opening swivel position can lock into place.

[0035] In some preferred embodiments, the lifting units can be locked in at least one further pivot position by means of the locking devices. This allows for a stepwise movement of the lifting units into the

[0036] The opening pivot position is enabled. For example, the lifting units each have a first pivot position in which they rest against the emergency escape hatch located in the exit opening. Preferably, the lifting units can be locked in at least one intermediate pivot position between the first pivot position and the opening pivot position by means of the locking devices. If the lifting units can pivot independently of each other, both lifting units can first be moved successively into the intermediate pivot position and locked there. Subsequently, both lifting units can be moved successively into the opening pivot position and locked there. Such a stepwise movement of the emergency escape hatch reduces the required force and reliably prevents the emergency escape hatch from jamming.

[0037] The first pivot position and the opening pivot position can be end positions of the lifting units. However, it is preferred that the lifting units can be pivoted beyond the first pivot position and / or beyond the opening pivot position.

[0038] Each lifting unit has an actuating section that can be pressed against the emergency exit hatch. The actuating section is therefore the part of the lifting unit that comes into direct contact with the emergency exit hatch when it is moved.

[0039] In some preferred embodiments, the actuating sections each have a roller arrangement and / or a slider arrangement. This reduces friction between the emergency escape hatch and the actuating sections, thus facilitating the sliding of the emergency escape hatch onto the wall section.

[0040] In some preferred embodiments, each lifting unit is assigned a corresponding holding unit, the holding units being attached to the wall section and limiting any pivoting movement of the assigned lifting unit in a direction away from the emergency exit hatch. The holding units securely hold the lifting units in the area of ​​the emergency exit hatch in the event of a change in the vehicle's position, e.g., during a rollover. Preferably, the holding units are detachably attached to the wall section. If the emergency exit hatch is removed and exposed to the wall section...

[0041] Once pushed on, the holding units can be released.

[0042] The lifting units can then be moved into a pivot position where they do not obstruct the occupants' exit. If necessary, the previously mentioned locking mechanisms must first be released. Preferably, each holding unit has a tension strap. The tension straps can be attached to the wall section on both sides of the exit opening, and in particular, they can be detachably fastened.

[0043] In some preferred embodiments, the lifting device includes a lever tool that can be mechanically coupled to the lifting units, allowing the lifting units to be pivoted by means of the coupled lever tool. The lever tool reduces the force required to move the emergency escape hatch using the lifting units. The lever tool has a coupling structure for connecting to the lifting units. Preferably, the lever tool has a square structure as its coupling structure. The lever tool is thus designed as a square lever tool, in particular as a 3 / 4-inch square lever tool. The square structure can be a square recess or a square projection. The lifting units then have a corresponding counter-coupling structure, designed as a square projection or a square recess, which can be coupled to the coupling structure of the lever tool.

[0044] In some preferred embodiments, the vehicle wall has a fastening device designed to detachably secure the emergency escape hatch located in the exit opening to the wall section. To move the emergency escape hatch out of the exit opening, the fastening provided by the fastening device must first be released.

[0045] In some preferred embodiments, the fastening device includes a fastening unit that can be released from both the first and second sides of the vehicle wall. A fastening unit designed in this way has the advantage of allowing the occupants to be rescued from the outside of the vehicle, i.e., from the second side. Preferably, the fastening unit is arranged in a through-opening of the emergency escape hatch. Preferably, an outwardly facing, e.g., radial, outer surface of the emergency escape hatch has at least one recess. This facilitates the removal of the emergency escape hatch from the second side. For example, a suitable tool, in particular a pry bar, can be inserted into such a recess from the second side to then lever the emergency escape hatch out of the escape opening.There may also be several indentations in the laterally facing, e.g., radial, outer surface of the emergency escape hatch. This facilitates the removal of the emergency escape hatch because several lever tools can be used simultaneously.

[0046] In some preferred embodiments, the fastening unit is provided to have a clamping screw and a clamping sleeve, wherein the clamping screw is screwed into the clamping sleeve.

[0047] In particular, the clamping screw is accessible from the first side and the clamping sleeve from the second side. Alternatively, the clamping sleeve can be accessible from the first side and the clamping screw from the second side. Specifically, the fastening unit can be released using the aforementioned lever tool, which can also be used to pivot the lifting units.

[0048] Preferably, the fastening element accessible from the first side, i.e., the clamping screw or the clamping sleeve, has a counter-coupling structure, in particular a square structure, which can be coupled to the coupling structure of the lever tool.

[0049] In some preferred embodiments, the fastening device includes a releasable locking screw that prevents the clamping screw from rotating. When the locking screw prevents the clamping screw from rotating, the fastening unit can be released by turning the clamping sleeve. The locking screw can protrude through a through-hole in the screw head of the clamping screw, which is arranged eccentrically with respect to the longitudinal center axis of the clamping screw. In particular, the locking screw is screwed into a threaded bore in the mounting plate. Preferably, the locking screw has a counter-coupling structure, especially a square structure, which can be coupled to the coupling structure of the lever tool. Therefore, the lever tool can also be used to release the locking screw.

[0050] In some preferred embodiments, the fastening device is provided with a releasable anti-rotation device that prevents rotation of the clamping sleeve. If the rotation of the clamping sleeve is blocked by the anti-rotation device, the fastening unit can be released by turning the clamping screw. The anti-rotation device can engage radially in a recess on the edge of the clamping sleeve, e.g., an arc-shaped section, and thereby prevent rotation of the clamping sleeve. Preferably, the anti-rotation device has a coupling structure, in particular a square structure, which can be released by a suitable tool.

[0051] In some preferred embodiments, the fastening device includes a mounting plate located on the first side of the vehicle wall and extending, in particular transversely, across the escape opening. Such a mounting plate enables a mechanically robust fastening of the emergency escape hatch to the wall section. Preferably, the mounting plate has a through-opening that aligns with the aforementioned through-opening in the emergency escape hatch, with the fastening unit being located in the through-opening of the emergency escape hatch and in the through-opening of the mounting plate.

[0052] In some preferred embodiments, the wall section has a projection that extends into a recess in the mounting plate. The engagement of the projection with the recess in the mounting plate reliably prevents unwanted movements of the mounting plate, such as displacement of the mounting plate in a plane parallel to the vehicle wall and / or rotation of the mounting plate about an axis perpendicular to the vehicle wall. Consequently, a particularly robust mechanical design of the mounting device can be achieved. Preferably, the projection of the wall section is dam-shaped. Preferably, the recess in the mounting plate is groove-shaped.

[0053] In some preferred embodiments, the fastening device includes at least one fastening strap by which the mounting plate is detachably attached to the wall section. Optionally, the fastening of the strap to the mounting plate and / or the fastening of the strap to the wall section can be detachable. Preferably, the fastening strap is detachably attached to the mounting plate by a ball lock pin. The ball lock pin allows the fastening to be released quickly and without tools. The fastening strap holds the mounting plate to the wall section independently of the emergency escape hatch. Depending on whether the emergency escape hatch is removed from the first side or the second side, this offers various advantages.If the emergency exit hatch is removed from the second side, i.e., from the outside of the vehicle, the advantage is that the mounting plate does not fall uncontrollably after the fastening unit is loosened, but is held in place by the fastening strap. If the emergency exit hatch is removed from the first side, i.e., from the inside of the vehicle, the advantage is that a step-by-step release of the fastening device is possible. In particular, in a first step, the fastening unit, especially the tensioning screw, can be loosened and removed, with the mounting plate initially still being held by the fastening strap. Only then is the fastening strap released from the mounting plate or from the wall section in order to then remove the mounting plate.Preferably, the fastening device has two fastening straps that are attached to the wall section on opposite sides of the exit opening. The two fastening straps are preferably attached to the wall section on opposite longitudinal sides of the exit opening. Both fastening straps are also attached to the mounting plate.

[0054] The aforementioned task is also solved by an armored vehicle with the features of the subordinate claim.

[0055] The armored vehicle has a vehicle wall designed as described above, with an emergency escape hatch, the first side of the vehicle wall facing the vehicle interior. The lifting device is therefore located inside the vehicle. Preferably, the vehicle wall is the vehicle floor (vehicle floor wall).

[0056] The features previously discussed in connection with the vehicle's hull can be used to further develop the armored vehicle.

[0057] The invention is explained in more detail below with reference to the figures, where identical or functionally identical elements are provided with identical reference numerals, possibly only once. The figures show:

[0058] Figure 1 shows an armored vehicle with a vehicle wall that has an emergency exit hatch;

[0059] Figure 2 shows an exploded view of the emergency exit hatch with a lifting device and a fastening device for the vehicle wall;

[0060] Figures 3a-3e show an opening of the emergency exit hatch when the vehicle is upside down, viewed from inside the vehicle; and

[0061] Figures 4a-4d show an opening of the emergency exit hatch when the vehicle is upside down, viewed from the outside of the vehicle.

[0062] Figure 1 shows a bottom view of an armored vehicle 200. The armored vehicle 200 has a vehicle wall 10 (hereinafter referred to as "vehicle wall 10") with an emergency escape hatch 12. In this context, the vehicle wall 10 is a vehicle floor wall 10 of the armored vehicle 200. The vehicle wall 10 has a wall section 14 with an escape opening 16 formed therein. The emergency escape hatch 12 is arranged in the escape opening 16 and closes the escape opening 16. Figure 1 shows a view of the side 18 of the vehicle wall 10 facing the outside of the vehicle. This side 18 is hereinafter referred to as the second side 18 of the vehicle wall 10. A side 20 of the vehicle wall 10, not visible in Figure 1 and facing the inside of the vehicle, is hereinafter referred to as the first side 20 of the vehicle wall 10.

[0063] The escape opening 16 is rectangular in shape. It has two longer longitudinal sides 22 and two shorter transverse sides 24. The emergency escape hatch 12 is also rectangular in shape.

[0064] The following section, with additional reference to Figures 2 and 3a, explains in more detail the construction of the vehicle wall 10 and, in particular, the emergency exit hatch 12. Figure 2 shows an exploded view of the emergency exit hatch 12, a lifting device 26 of the vehicle wall 10, and a fastening device 28 of the vehicle wall 10. Figure 3a shows the emergency exit hatch 12, located in the exit opening 16, as well as the lifting device 26 and the fastening device 28 in their assembled state.

[0065] In the present embodiment, the emergency exit hatch 12 is designed in a stepped configuration. For this purpose, the emergency exit hatch 12 has several armor plates 30. Starting from the first side 20, the size of the armor plates 30 increases towards the second side 18. The emergency exit hatch 12 has a circumferential seal 32 which, when the emergency exit hatch 12 is installed as intended, encloses the smallest of the armor plates 30.

[0066] The fastening device 28 is designed to detachably fasten the emergency escape hatch 12 arranged in the escape opening 16 to the wall section 14.

[0067] The fastening device 28 has a mounting plate 34, which is arranged on the first side 20 of the vehicle wall 10. The mounting plate 34 extends across the exit opening 16, from one longitudinal side 22 of the exit opening 16 to the other longitudinal side 22 of the exit opening 16. The wall section 14 has a dam-shaped projection 36, which in this case extends around the exit opening 16. The dam-shaped projection 36 projects into two groove-shaped recesses 38 of the mounting plate 34. This prevents rotational movements and displacements of the mounting plate 34 relative to the wall section 14.

[0068] The mounting plate 34 is attached to the wall section 14 by two mounting straps 40. The mounting straps 40 are attached to the wall section 14 by a respective eyelet 42 and to the mounting plate 34 by a respective ball lock pin 44. The mounting straps 40 can be released from the mounting plate 34 by removing the ball lock pins 44. In addition to the actual strap element, each mounting strap 40 has a tensioner 41 (see Figure 2).

[0069] The mounting plate 34 and the emergency escape hatch 12 each have a through-opening 46, 48. The mounting device 28 has a fastening unit 50, which is arranged in the through-opening 46 of the mounting plate 34 and in the through-opening 48 of the emergency escape hatch 12 and is designed to fasten the emergency escape hatch 12 to the mounting plate 34. The fastening unit 50 can be released from both the first side 20 of the vehicle wall 10 and the second side 18 of the vehicle wall 10.

[0070] The fastening unit 50 comprises a clamping screw 52 and a clamping sleeve 54. The clamping screw 52 is screwed into the clamping sleeve 54. The clamping screw 52 is accessible from the first side 20, and the clamping sleeve 54 from the second side 18. The clamping screw 52 has a square recess and can be loosened by a tool with a suitably sized square projection. The square recess of the clamping screw 52 is a 3 / 4-inch square recess.

[0071] The clamping sleeve 54 has a square recess and can be loosened by a tool with a suitably dimensioned square projection (see Figure 4b). In this case, the square recess of the clamping sleeve 54 is a 1 / 2-inch square recess. If access to the square recess of the clamping sleeve 54 is not currently required, a plug 56 may be inserted into the square recess (see Figure 4a).

[0072] The fastening device 28 also has a releasable locking screw 58 that prevents the clamping screw 52 from rotating. The locking screw 58 projects through an eccentrically arranged, in this case arc-shaped, through-hole 60 in the screw head 62 of the clamping screw 52. This reliably prevents the clamping screw 52 from rotating. The locking screw 58 is screwed into a threaded bore 64 in the mounting plate 34.

[0073] The locking screw 58 has a square recess and can be loosened by a tool with a suitably sized square projection. In this case, the square recess of the locking screw 58 is a 3 / 4-inch square recess.

[0074] The fastening device 28 also features a releasable anti-rotation device 66, which prevents rotation of the clamping sleeve 54. The anti-rotation device 66 engages radially in a recess 68 on the edge of a base plate 70 of the clamping sleeve 54. This reliably prevents rotation of the clamping sleeve 54. The anti-rotation device 66 is screwed into a threaded bore 72 of the emergency escape hatch 12. The threaded bore 72 is designed as a stepped bore (see Figure 4c).

[0075] The anti-rotation device 66 has a square recess and can be released by a tool with a suitably sized square projection (see Figure 4b). In this case, the square recess of the anti-rotation device 66 is a 1 / 2-inch square recess. If access to the square recess of the anti-rotation device 66 is not currently required, a plug 74 may be inserted into the square recess (see Figure 4a).

[0076] The lifting device 26 has two lifting units 76 arranged on opposite sides of the escape opening 16. In this case, the two lifting units 76 are arranged on opposite sides 24 of the escape opening 16. The lifting units 76 are pivotally mounted on the wall section 14. By pivoting the lifting units 76, the emergency escape hatch 12 can be forcibly moved out of the escape opening 16 when the fastening device 28 is released. Figure 4a shows the lifting units 76 in a pivot position, which is referred to below as the first pivot position. In the first pivot position, actuating sections 78 of the lifting units 76 are in contact with the emergency escape hatch 12, with the emergency escape hatch 12 being located in the escape opening 16.Starting from the first pivot position, the lifting units 76 can be pivoted at least to an opening pivot position in which the emergency escape hatch 12 is moved sufficiently far out of the escape opening 16 that the emergency escape hatch 12 can be slid onto the wall section 14 in a direction parallel to the wall section 14. In this case, the lifting units 76 are pivotally mounted by a different bearing part 80, which is welded to the wall section 14. The construction of one of the lifting units 76A is explained in more detail below. The other lifting unit 76B is constructed identically.

[0077] The lifting unit 76A has two lifting arms 82 which are non-rotatably connected to a common bearing axis 84. The bearing axis 84 is rotatably mounted in the associated bearing part 80. For this purpose, the bearing axis 84 has two sliding bearings 86. The lifting arms 82 are angled.

[0078] The actuating section 78 of the lifting unit 76A is formed by a roller assembly 86. The roller assembly 86 comprises two axles 88, which are rotatably mounted at one end of the lifting arms 82, spaced apart from the bearing axis 84. The roller assembly 86 facilitates the displacement of the emergency escape hatch 12 onto the wall section 14. The axles 88 are held on the lifting arms 82 by fastening units 89.

[0079] The lifting unit 76A is also associated with two locking bolts 90. The locking bolts 90 are designed to lock the lifting unit 76A at least in the opening pivot position. For this purpose, the lifting unit 76A, in particular the bearing axis 84, has a counter-locking structure into which the locking bolts 90 can engage. The locking bolts 90 and the counter-locking structure together form a locking device 104. Locking the lifting unit 76A facilitates the removal of the emergency exit hatch 12, as will be explained in more detail below. In this case, the locking bolts 90 are designed to additionally lock the lifting unit 76A in at least one intermediate pivot position between the first pivot position and the opening pivot position.

[0080] As can be seen in Figure 3a, each lifting unit 76 is assigned a corresponding holding unit 92. The holding units 92 are detachably attached to the wall section 14 and limit a pivoting movement of the assigned lifting unit 76 in a pivoting direction away from the emergency exit hatch 12. In this case, each holding unit 92 has a tension strap 94 for this purpose.

[0081] The following section, with reference to Figures 3a to 3e, explains in more detail how to open the emergency exit hatch 12 from the first side 20, i.e., from inside the vehicle. It is assumed that the vehicle 200 is upside down.

[0082] In a first step (see Figure 3a), the locking screw 58 is loosened. The lever tool 96 shown in Figure 3d can be used for this purpose. The locking screw 58 is not secured in this case and will fall out once completely loosened.

[0083] In a second step (see Figure 3b), the clamping screw 52 is loosened. The lever tool 96 shown in Figure 3d can also be used for this purpose. Because the clamping sleeve 54 is secured by the anti-rotation device 66, the clamping screw 52 can be loosened from the first side 20. When the clamping screw 52 is loosened, the mounting plate 34, together with the clamping screw 52, ​​lowers. After the clamping screw 52 is completely loosened, the mounting plate 34, including the clamping screw 52, ​​falls approximately 15 cm downwards and is caught there by the fastening straps 40. The clamping screw 52 is secured to the mounting plate 34.

[0084] In a third step (see Figure 3c) the mounting plate 34 is released from the mounting straps 40 by removing the ball locking pins 44.

[0085] In a fourth step (see Figure 3d), the emergency exit hatch 12 is moved out of the exit opening 16 by the lifting units 76. The previously mentioned lever tool 96 can be used for this purpose. Each lifting unit 76 has a counter-coupling structure 98 in the area of ​​the bearing axis 84, designed as a square recess, which can be coupled to a square projection of the lever tool 96 (not visible). If the square projection of the lever tool 96 is coupled to the square recess of one of the lifting units 76, this lifting unit 76 can be pivoted by means of the lever tool 96.

[0086] In particular, the lifting units 76 are first moved one after the other into the intermediate pivot position using the lever tool 96 and locked there. Subsequently, the lifting units 76 are moved one after the other into the

[0087] The opening pivot position is brought and locked in place. The emergency exit hatch 12 can then be slid onto the wall section 14.

[0088] In a fifth step (see Figure 3e), the two tension straps 94 are removed. In addition, the locking bolts 90 are released and the lifting units 76 are pivoted so that they do not block the exit opening 16. The occupants can then leave the vehicle 200 through the exit opening 16.

[0089] The emergency exit hatch 12 can also be opened from the first side 20 when the vehicle 200 is in its normal position. The fastening device 28 is released as previously explained. The emergency exit hatch 12 then falls to the ground due to gravity, so that the use of the lifting units 76 is not necessary.

[0090] The following explains, with reference to Figures 4a to 4d, how to open the emergency exit hatch 12 from the second side 18, i.e., from the outside of the vehicle. It is assumed that the vehicle 200 is upside down.

[0091] In a first step (see Figure 4a) plugs 56, 74 are removed.

[0092] In a second step (see Figure 4b), the anti-rotation device 66 is released using a suitable tool. In a third step (see Figure 4c), the clamping sleeve 54 is released using a suitable tool. Because the clamping screw 52 is secured by the locking screw 58, the clamping sleeve 54 can be released from the second side 18. When the clamping sleeve 54 is released, the mounting plate 34, together with the clamping screw 52, ​​lowers inside the vehicle. After the clamping sleeve 54 is completely released, the mounting plate 34, including the clamping screw 52, ​​falls downwards and is caught by the fastening straps 40.

[0093] In a fourth step (see Figure 4d), the emergency escape hatch 12 is, for example, levered out of the escape opening 16 using a mounting iron. The emergency escape hatch 12 has two recesses 102 on its radial outer surface 100, into each of which a mounting iron can be inserted.

[0094] Once the emergency exit hatch 12 has been removed, the mounting plate 34 and the lifting units 76 can be removed from the second side 18, i.e. from the outside of the vehicle, as explained above.

[0095] The emergency exit hatch 12 can also be opened from the second side 18 when the vehicle 200 is in its normal position. The anti-rotation device 66 and the tension sleeve 54 are released as previously explained. The emergency exit hatch 12 then falls to the ground due to gravity.

[0096] Due to the high weight of the emergency exit hatch 12, suitable securing, e.g. using square timbers, should be carried out before opening.
