DOOR OR HATCH ARRANGEMENT, LOCKING MECHANISM, AND VEHICLE OR BUILDING

Description

[0001] The invention relates firstly to a door or hatch assembly for a vehicle or a building, wherein the door or hatch assembly comprises a leaf pivotably mounted in a frame for closing a frame opening. Furthermore, the invention relates to a locking mechanism for a door or hatch assembly and to a vehicle or a building with such a door or hatch assembly.

[0002] Numerous ship doors and hatch covers for vessels that are reliably closing against pressure waves or are shock-resistant are known from the prior art. DE 34 25 890 C2 discloses a ship door or hatch assembly with a frame and a leaf that is movable within the frame and mechanically lockable to it. An elastic hose connected to a pressure medium source is arranged around one of the opposite narrow sides of the frame and leaf as a dynamic seal. When pressurized, this elastic hose presses between the narrow sides of the frame and the leaf, creating a seal. Upon pressure release, it lifts away from the opposite narrow side to form an annular gap. The leaf is pivotally connected to the frame at one edge by means of two hinges.The locking of the leaf to the frame in the closed state of the door is carried out in the traditional way with the help of a large number of leaf-side latches which can be pivoted by means of a central door handle and which engage with corresponding frame-side locking lugs in the locked state.

[0003] US Patent 10,221,595 B2 discloses a door assembly with a door leaf pivotally mounted in a frame. A bolt is provided for closing the door, which is actuated by a rod-like operating element in the door leaf. In the open position, the bolt is fully retracted into the frame. In the locked position, the operating element projects into the frame, and the bolt projects out of the frame into the door leaf.

[0004] US Patent 4,343,065 A1 discloses a locking system for two parts that are to be locked together. The parts are locked by means of two semicircular locking elements. In the open position, one locking element is located in one of the parts. To lock, the locking elements are pivoted by 90° and then each project halfway into the other part. For pivoting, each locking element has a bore-like receptacle. The object of the invention is to provide an improved door or hatch arrangement for a vehicle, in particular a surface or underwater vehicle, or a building. Furthermore, it is an object of the invention to disclose a locking mechanism for such a door or hatch arrangement, as well as a vehicle or a building with such a door or hatch arrangement.

[0005] The aforementioned problem is solved by providing the door or hatch assembly with at least one multi-part bolt, formed by one sub-body and at least one further sub-body. In an unlocked state, at least one sub-body is positioned in the leaf and the at least one further sub-body in the frame, whereas in a locked state, the sub-bodies are partially located in both the frame and the leaf. This results in smooth operation requiring only minimal actuation force while still providing robust and pressure-wave-resistant or shock-resistant locking of the door or hatch assembly. The door or hatch assembly can be sealed, if necessary, by means of additional sealing elements. In the context of this description, the term "vehicle" refers to land vehicles, watercraft, underwater vehicles, and spacecraft.

[0006] In a technically advantageous embodiment, a first sub-body on the leaf side is designed as a first partial round profile, and a second sub-body on the frame side is designed as a second partial round profile. This allows for the simple manufacture of the sub-bodies from standard semi-finished products. Preferably, two partial round profiles are each designed as mutually symmetrical half-cylinders, which, when placed congruently at their respective flat sides or contact surfaces, form a (solid) cylinder. The sub-bodies can also be designed, for example, as cylinders flattened on both sides with the same or different widths, as hemispheres, or as layers of spheres.

[0007] Preferably, the first sub-body is rotatably mounted about an associated longitudinal axis, and the second sub-body is rotatably mounted about an associated longitudinal axis. This results in a structurally simple and mechanically robust design for the central locking mechanism of the round cylinder, which is preferably formed with two partial round profiles. Preferably, the sub-bodies are mounted at least partially in a form-fit manner.

[0008] In a further advantageous embodiment, a first bearing shell for supporting the first sub-body is positively connected to a first support profile, and the first support profile is arranged in the leaf. A second bearing shell for supporting the second sub-body is positively connected to a second support profile, and the second support profile is arranged in the frame. The bearing shells enable particularly smooth operation. This provides an easily manufactured, durable, and mechanically robust connection between the first bearing shell and the first support profile, which is part of the leaf. The support profile is integrated into the leaf in such a way that, in the unlocked state, a flat contact surface of the semi-circular profile is essentially flush with the leaf frame. Similarly, an easily manufactured, durable, and mechanically robust connection between the second bearing shell and a second support profile is provided.The second support profile is integrated into the sheet in such a way that a flat contact surface of the associated partial round profile is essentially flush with a frame in the locked state.

[0009] According to the invention, one of the sub-bodies can be actively pivoted about the associated longitudinal axis by means of an actuating device, and the other sub-body passively follows the pivoting movement performed by the first sub-body. Consequently, the device engineering effort is reduced if only one sub-body is driven and the other is passively driven by it.

[0010] In a favorable further development, the passive sub-body has at least one guide pin, wherein the guide pin(s) are each slidably received in an associated guide within the respective support profile. The at least one guide pin reliably guides the partial round profile and simultaneously secures it against falling out of the associated bearing shell. The two ends of the guide, particularly in the form of an approximately annular sector-shaped groove, also serve as a stop for the rotational movement of the guide pin within the groove.

[0011] In a technically advantageous embodiment, the active sub-body has at least one drive pin that interacts with the actuating device, wherein the drive pin(s) are each slidably received in the associated guide in the respective support profile. This allows the second partial circular profile to be actively pivoted by preferably approximately 90° about the second longitudinal axis by means of the actuating device. Furthermore, the drive pin serves as a safeguard against the partial circular profile falling out of the associated bearing shell and, in conjunction with the two ends of the annular sector-shaped groove, as a stop or travel limiter against the completed rotational movement.

[0012] Preferably, the second sub-body on the frame side is the active sub-body, which can be actively pivoted about the associated longitudinal axis by means of the actuating device, and the first sub-body on the leaf side is the passive sub-body, which passively follows the pivoting movement performed by the second sub-body. Consequently, the active part of the actuating device is located only within the stationary frame.

[0013] Preferably, a leaf frame has a wedge-shaped first chamfer at least partially at an angle to a perpendicular line of the leaf, and a jamb frame has a second chamfer that is complementary to this, at least partially, wherein the first chamfer of the leaf frame is oriented from an outer surface of the leaf towards an inner surface. Due to the at least partially slightly wedge-shaped complementary design of the leaf frame and jamb frame, the door or hatch assembly can be closed smoothly and without jamming and subsequently locked.

[0014] In a further advantageous embodiment, it is provided that, in the locked state, the leaf frame and the jamb frame abut each other at least partially and essentially without gaps, with the contact surfaces of the partial bodies lying essentially completely outside the plane of contact between the leaf frame and the jamb frame. This enables a reliable and mechanically robust locking of the leaf in the jamb when the door or hatch assembly is closed. Preferably, the adjacent contact surfaces of the partial round profiles are oriented essentially transversely, i.e., at approximately 90° to the leaf frame and the jamb frame, in the locked state.

[0015] Preferably, the bearing shells are made of a friction-reducing material, and the support profiles are preferably made of a high-strength material, such as a steel alloy. This ensures permanently smooth and low-wear operation of the locking device while simultaneously providing high shock resistance to the door or hatch assembly. Suitable friction-reducing materials include, among others, self-lubricating non-ferrous metal alloys such as bronze or similar materials.

[0016] According to one embodiment, several multi-part bolts are provided, which are mechanically interconnected such that when the actuating device is activated, all parts of the bolts are moved. As a result, a secure and mechanically robust locking mechanism is achieved across the entire perimeter of the door or hatch. At the same time, this results in minimal hardware complexity with only one central actuating device.

[0017] Furthermore, the aforementioned problem is solved by a locking mechanism for a door or hatch arrangement, in particular for a vehicle or a building, comprising at least one multi-part bolt formed with a partial body and with at least one further partial body, wherein one partial body is arranged to be located in a leaf of the door or hatch arrangement in an unlocked state and to be located partially in both the leaf and the frame of the door or hatch arrangement in a locked state, and wherein the at least one further partial body is arranged to be located in the frame in an unlocked state and to be located partially in both the frame and the leaf in a locked state.One of the sub-bodies can be actively pivoted about its associated longitudinal axis by means of an actuating device, and the other sub-body passively follows the pivoting movement of the first sub-body. As a result, the door or hatch assembly can be easily locked while simultaneously maintaining high mechanical load-bearing capacity.

[0018] Furthermore, the aforementioned problem is solved by a vehicle or a building with a door or hatch arrangement according to any one of claims 1 to 10 or with a locking mechanism according to claim 12. As a result, a secure and mechanically robust closure of a frame opening of a building or vehicle is ensured.

[0019] A preferred embodiment of the invention is explained in more detail below with reference to schematic figures. The same structural elements are shown in the figures, each with the same reference numerals. Figure 1 shows a perspective front view of a door or hatch arrangement according to the invention with a locking mechanism; Figure 2 shows a perspective rear view of the door or hatch arrangement. Fig. 1 Figure 3 shows an enlarged perspective top view of the locking mechanism of the door or hatch assembly of Fig. 1 in an unlocked state, Figure 4 shows the locking mechanism of Fig. 3 Figure 5 shows a schematic cross-sectional representation of the locking mechanism in the unlocked state, and Figure 6 shows a schematic cross-sectional representation of the locking mechanism in the locked state.

[0020] The Figure 1Figure 1 shows a perspective front view of a door or hatch arrangement according to the invention with a locking mechanism. A door or hatch arrangement 100 for a building, structure, or vehicle (not shown), such as a surface or underwater vessel or the like, comprises, among other things, a leaf 106 pivotably mounted in a fixed frame 102 for closing a frame opening 110.

[0021] The sheet 106 is pivotally connected to the frame 102 by means of a first and a second hinge 112, 114, the hinges 112, 114 being attached to the frame 102, for example, by means of a profiled hinge band 116 with an L-shaped cross-sectional geometry.

[0022] The leaf 106 of the door or hatch assembly 100 has an inner surface 120 and an outer surface 122, wherein any shock or pressure wave 124 originating from an outer space 126 acts on the outer surface 122 of the leaf 106. A preferred closing direction 128 of the leaf 106 extends in the direction of the shock or pressure wave 124 originating from the outer space 126 towards an interior space 130.

[0023] The door or hatch assembly 100 is equipped with a locking mechanism 136, which includes, among other things, a leaf-side first support profile 138 and a frame-side second support profile 140. The first support profile 138 is fastened in a leaf frame 142, while the second support profile 140 is fastened in a frame 144 of the door or hatch assembly 100 in a suitable manner, for example, by welding, screwing, or the like. For this purpose, the second support profile 140 is shown here, by way of example, connected to the frame 102 by means of a fastening tab 146 extending approximately perpendicular to it. The locking mechanism 136 is shown here, by way of example, as being operable by means of an actuating device 148. The actuating device 148 can be operated manually or locally or remotely by means of electric, pneumatic, and / or hydraulic actuators.

[0024] The locking mechanism 136 of the door or hatch assembly 100 further comprises a multi-part bolt 150, which is shown here only as an example in two parts: a leaf-side first part 152 and a further, frame-side part 154. In the unlocked state of the locking mechanism 136 illustrated here, the leaf-side part 152 is positioned in the leaf 106 and the further, frame-side part 154 is positioned in the frame 102. In a locked state (see in particular the following illustrations), the locking mechanism 136 is fully locked. Fig. 4 , 6 The two sub-bodies 152 and 154 are, however, partially located in both the frame 102 and the leaf 106 of the door or hatch assembly 100. The leaf-side sub-body 152 is rotatably or pivotably mounted in the first support profile 138, and the frame-side sub-body 154 is correspondingly rotatably or pivotably mounted in the frame-side support profile 140.

[0025] The leaf-side, first partial body 152 is shown here only by way of example as a first partial round profile 160, and the frame-side, second partial body 154 is shown only by way of example as a second partial round profile 162. In a preferred embodiment of the invention, the first partial round profile 160 is designed as a first half-cylinder 164 and the second partial round profile 162 is designed as a second half-cylinder 166, wherein the half-cylinders 164 and 166 are symmetrical to each other and, when placed against each other at their flat sides or contact surfaces, form a full cylinder. The term "half-cylinder" defines a full cylinder divided in the middle with a semicircular cross-sectional geometry, wherein the term "flat side" defines the planar surface in the longitudinal direction.For example, any rotationally symmetric bodies such as cylinders, ellipsoids, spindles, barrel bodies, cones, spheres or the like, which are divided at least once in the longitudinal direction, either centrally or eccentrically, can form the multi-part bar 150.

[0026] The first sub-body 152 is rotatable or pivotable about an associated longitudinal axis 172 in the support profile 138 and the second sub-body 154 is rotatable about an associated longitudinal axis 174 in the second support profile 140.

[0027] The Figure 2 illustrates a perspective rear view of the door or hatch arrangement of Fig. 1The frame opening 110 of the door or hatch assembly 100 can be closed, if necessary, by pivoting the leaf 106 in the closing direction 128 to separate the outer space 126 from the inner space 130. The leaf 106 is pivotally mounted by the two hinges 112 and 114. The leaf 106 has an outer surface 122 opposite the closing direction 128 and an inner surface 120 facing away from it. The leaf frame 142, which runs essentially perpendicular to the inner surface 120 and the outer surface 122, integrates the leaf-side partial body, or the first partial round profile designed as a half-cylinder, which is concealed here. Similarly, the frame-side partial body 154 is integrated into the frame 144 of the frame 102 by means of the second support profile 140. The second support profile 140 on the frame side is shown here as an example connected to the frame 102 by means of the fastening tab 146.The second sub-body 154 is realized as a second partial round profile 162 and in the form of the second half-cylinder 166. The actuation of the frame-side, second sub-body 154 is effected by means of the actuating device 148.

[0028] The Figure 3 shows an enlarged perspective top view of the locking mechanism of the door or hatch assembly of Fig. 1 in an unlocked state. The door or hatch assembly 100 is shown in the illustration of Fig. 3In the closed state, the leaf 106 completely closes the frame opening 110 of the frame 102 of the door or hatch assembly 100. The leaf 106 has an inner surface 120 and an outer surface 122. Ideally, in the closed state of the door or hatch assembly 100 illustrated here, the leaf frame 142 lies flush against the frame 144, creating an imaginary common contact plane 190. Between the outer surface 122 of the leaf 106 and the frame 102, a circumferential, rebate-like gap 192 remains in the closed state of the door or hatch assembly 100. This gap can, for example, serve as a receiving space for a sealing element (not shown).

[0029] The multi-part bolt 150 of the locking mechanism 136 is constructed with the leaf-side sub-body 152 and the frame-side sub-body 154, wherein the leaf-side sub-body 152 is shown here only as an example of the first half-cylinder 164 and the frame-side sub-body 154 as a half-cylinder 166 symmetrical to the first half-cylinder 164. The first half-cylinder 164 is rotatably mounted in a first bearing shell 198 about its associated longitudinal axis 172, and the second half-cylinder 166 is mounted in a second bearing shell 200 about its associated longitudinal axis 174. The first bearing shell 198 is positively connected to the leaf-side first support profile 138. Similarly, the second bearing shell 200 is fixedly connected to the frame-side second support profile 140. The two half-cylinders 164, 166 are in opposite positions in the closed state of the door or hatch arrangement 100 shown here.

[0030] For the sake of clarity in the drawing, one of the flat sides of the first half-cylinder 164, which is not shown here, forms a contact surface 206. When the door or hatch assembly 100 is closed, this surface preferably rests fully against a flat side of the second half-cylinder 166, which forms another contact surface 208. The contact surfaces 206 and 208, or the flat sides of the half-cylinders 164 and 166 of the locking mechanism 136, lie within the contact plane 190, and the door or hatch assembly 100 can be opened and closed by pivoting the leaf 106 within the frame opening 110. Due to the directly adjacent contact surfaces 206, 208 of the half-cylinders 164, 166, these together form, in the closed state of the door or hatch arrangement 100 - regardless of the locking state - the cylindrical bolt 150 of the locking mechanism 136, which is divided in the middle in the direction of the longitudinal center axes 172, 174.

[0031] In this case, the longitudinal axes 172, 174 of the half-cylinders 164, 166 running in the contact surfaces 206, 208 coincide in an imaginary, common axis of rotation 176 of the bolt 150 of the locking mechanism, which is exemplarily designed in two parts here.

[0032] The bearing shells 198, 200 have an approximately semicircular annular cross-sectional geometry and are made of a friction-reducing or self-lubricating material, such as a non-ferrous metal alloy in the form of bronze or the like. The support profiles 138, 140 are preferably made of a high-strength steel alloy or the like.

[0033] The frame-side second half-cylinder 166 can be actively rotated about its associated longitudinal axis 174 by means of the actuating device 148, whereby the leaf-side first half-cylinder 164 is only passively rotated due to its contact surface 206 being in contact with the contact surface 208 of the second half-cylinder 166, or the first half-cylinder 164 only passively follows the rotational movement of the frame-side second half-cylinder 166, which is actively rotated by means of the actuating device 148.

[0034] The passive, leaf-side first half-cylinder 164 is shown here with two radially outwardly directed guide pins 214, 216, each of which is slidably received in an associated guide 218, 220 of the first support profile 138. The two guides 218, 220 are shown here as pie-slice fanned-out grooves. For the sake of clarity, the unlabeled ends of the guides 218, 220 serve as stops to limit the rotational or pivoting movement of the half-cylinders 164, 166 to approximately a quarter turn or a rotational or pivoting angle of approximately 90°. The same applies to the frame-side second half-cylinder 166, whose guide pins and guides are shown in the illustration. Fig. 3are completely concealed. Due to the guide, the half-cylinders 164, 166 are reliably guided within the bearing shells 198, 200 of the support profiles 138, 140 even when the door or hatch arrangement 100 is open, and are simultaneously secured against falling out.

[0035] The leaf frame 142 has, at least in sections, a wedge-shaped first chamfer 232 extending at an angle α relative to a vertical line 230 of the leaf 106. Correspondingly, the frame 144 has a second chamfer 234 that is complementary to the first chamfer 232, with the first chamfer 232 extending inclined from the outer leaf surface 122 towards the inner leaf surface 120. The wedge-shaped chamfers 232 and 234 are positioned opposite each other on the leaf and frame 142 and 144 to ensure a tight seal. The vertical line 230 is oriented essentially orthogonally to the leaf 106, i.e., to the inner leaf surface 120 and the outer leaf surface 122.Due to the wedge-shaped chamfers 232, 234, the door or hatch assembly 100 opens and closes smoothly and without jamming, while at the same time exhibiting exceptionally high strength against forces acting on the outer surface of the sheet 122, such as pressure or shock waves, etc.

[0036] The Figure 4 shows the locking mechanism of Fig. 3 in the locked position. The leaf 106 of the door or hatch assembly 100 has the inner leaf 120 and the outer leaf 122 and completely closes the frame opening 110 of the frame 102.

[0037] The leaf frame 142 rests at least partially against the frame 144. The leaf frame 142 preferably has the first chamfer 232, which is inclined at an angle α with respect to the vertical 230, where the angle α is on the order of 5°. A chamfer 234, complementary to the chamfer 232, is provided on the frame 144.

[0038] In the locked state, the half-cylinders 164, 166 of the locking mechanism 136 are rotated or pivoted by the actuating device 148 by approximately 90°, e.g., counterclockwise, about their associated longitudinal axes 172, 174 or the common axis of rotation 176, respectively, relative to the contact plane 190 defined by the leaf and frame in the closed state of the door or hatch assembly 100, whereby the flat contact surfaces 206, 208 or flat sides of the half-cylinders 164, 166 abut each other essentially without gaps. As a result, the leaf 106 is reliably locked within the frame 102.During the locking process, the frame-side, second half-cylinder 166 is actively rotated by means of the actuating device 148, whereas the leaf-side half-cylinder 164 adjacent to it only passively follows the approximately quarter turn of the actively driven second half-cylinder 166, i.e. the second half-cylinder 166 takes the first half-cylinder 164 with it every time the locking mechanism is locked and unlocked.

[0039] Starting from the in Fig. 4 The unlocked position, as illustrated, is achieved by rotating the half-cylinders 164, 166 clockwise by approximately 90°, with the door or hatch assembly 100 initially still closed. The synchronous pivoting or rotation of the half-cylinders 164, 166 is only possible when the door or hatch assembly is closed, since only in this case do the contact surfaces 206, 208 of the two half-cylinders 164, 166 rest against each other.

[0040] The Figure 5 Figure 1 shows a schematic cross-sectional view of the locking mechanism in the unlocked state. In the leaf 106 of the door or hatch assembly 100, the first support profile 138 with the first bearing shell 198 attached therein is arranged. The leaf-side sub-body 152 is designed as the first partial round profile 160 in the form of the first half-cylinder 164. The same applies to the second, frame-side sub-body 154, which represents the second partial round profile 162, designed here in the form of the second half-cylinder 166.

[0041] The first bearing shell 198 is designed to receive the first half-cylinder 160 around its associated longitudinal axis 172, which here runs perpendicular to the plane of the drawing. Accordingly, the second support profile 140 is arranged in the frame 102, in which the second bearing shell 200 is attached for the rotatable reception of the second half-cylinder 166.

[0042] The contact surfaces 206, 208, or half-sides of the half-cylinders 164, 166, lie practically gap-free against each other and together form the multi-part bolt 150 of the locking mechanism 136. The leaf frame 142 and the jamb frame 144, in the closed but not yet locked state of the door or hatch assembly 100, also lie against each other and form the contact plane 190. Due to the fact that the contact surfaces 206, 208 of the two half-cylinders 164, 166 lie directly against each other without gaps and at the same time run in the contact plane 190 of the leaf and frame 142, 144, the locking mechanism 136 is in the unlocked state and the door or hatch arrangement 100 can be easily opened and closed again if necessary by pivoting the leaf 106 out of the frame 102.

[0043] The first half-cylinder 164, rotatably mounted in the first bearing shell 198, is guided in the guide 218 by means of the guide pin 214 and simultaneously secured against falling out. Similarly, the second half-cylinder 166, rotatably mounted in the second bearing shell 200, is guided in a guide 242 by means of a guide pin 240 and secured against falling out.

[0044] The guide pin 240 can simultaneously function as a drive pin 248, which, for example, can be connected by means of an associated, unlabeled ball head to a ball socket of an actuator (also not shown) as part of the actuating device according to the specifications of the Figs. 1 to 4 The locking mechanism 136 is actuated by rotating or pivoting the half-cylinders 164, 166. Each half-cylinder 164, 166 can have more than one radially outwardly directed guide pin, each of which runs in associated guides.

[0045] To lock the door or hatch assembly 100, the second half-cylinder 166 is rotated by means of the drive bolt 248 in a circumferential direction U or, for example, counterclockwise by about 90°, that is, approximately a quarter turn about the coinciding longitudinal axes 172, 174, until the two half-cylinders 164, 166 reach the position of Fig. 5 have been engaged and the door or hatch assembly 100 is in its fully locked position. In this case, the actively driven second half-cylinder 166 engages the passive first half-cylinder 164, which is in contact with it, with virtually no play due to the ideally full-surface contact between the two contact surfaces 206, 208, thus making an active, leaf-side drive of the first half-cylinder 164 unnecessary.

[0046] In this process, the at least one guide pin 240 of the second half-cylinder 166 moves within the associated guide 242 from a fourth stop A 4 to a third stop A 3, and the guide pin 214 of the first half-cylinder 164 slides accordingly from a first stop A 1 to a second stop A 2 of the leaf-side guide 218.

[0047] Furthermore, from the Fig. 5 the mutually complementary chamfers 232, 234 of the leaf and frame 142, 144 with the (incline) angle α are evident.

[0048] The Figure 6 illustrates a schematic cross-sectional representation of the locking mechanism in the locked state.

[0049] The adjacent contact surfaces 206, 208 of the half-cylinders 164, 166 extend from their position in the direction of the approximate 90° rotation of the half-cylinders 164, 166 about the longitudinal axes 172, 174 caused by the drive bolt 248. Fig. 5 in the direction of travel U or counterclockwise at approximately right angles to the common contact plane 190 of the leaf and frame 142, 144, whereby in Fig. 6 The fully locked state of the locking mechanism 136 of the door or hatch assembly 100 is reached. In this process, the guide pin 214 of the half-cylinder 164 performs its passive rotational movement.

[0050] Opening the door or hatch assembly 100 in the locked state is practically impossible, even with a high degree of mechanical force. By rotating the two half-cylinders 164, 166 together counterclockwise (i.e., clockwise) by approximately 90° using the drive bolt 248, the unlocked state of the locking mechanism can be restored. Fig. 5 produce.

[0051] To increase the mechanical load-bearing capacity, the door or hatch arrangement 100 can have a plurality of locking mechanisms arranged circumferentially, preferably at uniform intervals from each other, each of which is constructed in the manner of the locking mechanism 136, and which can preferably be actuated simultaneously and from a central location by means of an actuator.

[0052] The invention relates to a door or hatch arrangement 100 for a vehicle or a building, wherein the door or hatch arrangement 100 has a leaf 106 pivotably received in a frame 102 for closing a frame opening 110.According to the invention, the door or hatch assembly 100 has at least one multi-part bolt 150, which is formed with a partial body 152 and at least one further partial body 154, wherein in an unlocked state at least one partial body 152 is positioned in the leaf 106 and the at least one further partial body 154 is positioned in the frame 102, whereas in a locked state the partial bodies 152, 154 are partially located in both the frame 102 and the leaf 106, wherein one of the partial bodies 154 can be actively pivoted about an associated longitudinal axis 172, 174 by means of an actuating device 148, and the other partial body 152 passively follows the pivoting movement performed by the first partial body 154.
