Description

The present invention relates to a device for closing or opening a flap. The flap is, for example, a door or a window. Buildings typically require the installation of building services such as heating pipes, water pipes, electrical wiring, and / or related equipment. Often, it is necessary to maintain access to these installations even when they are concealed, particularly when concealed within the wall or behind paneling. Therefore, at least one access panel, also known as an inspection hatch or access door, is usually installed at various locations within the building. This lockable or operable panel ideally provides easy access to the installations. To make maintenance of the installations as simple and therefore as cost-effective as possible, such flaps should ideally be easy to open and close securely. Ideally, this should also cause no damage to the flap and / or the component into which it is installed. Such a component is, in particular, a building wall, a building ceiling, or a building floor. This is a greater challenge with drywall partitions or suspended ceilings than with solid walls made of masonry or concrete. For the more cost-effective drywall partitions or ceilings, gypsum plasterboard panels are used, which are attached to a substructure made of metal or wood. This substructure is also called a stud wall. Drywall partitions usually only serve a partition function and have little to no load-bearing capacity. The problem is that opening and / or closing the flap can quickly lead to unsightly signs of wear on the flap or the adjacent component(s). An additional problem arises if the flap has to be installed in confined spaces. Depending on the installation situation, providing the largest possible flap opening, which would improve accessibility to the installations, is often not possible. Therefore, the object of the present invention is to provide a device for closing or opening a flap that solves the aforementioned problems. In particular, a device for closing or opening a flap is to be provided that enables reliable and safe closing or opening of the flap with simple handling, in order to minimize damage to the flap and / or the component adjacent to the flap. This problem is solved by a device for closing or opening a flap according to claim 1. The device has a holding body for mounting on a first component and a base body for mounting on a second component, wherein the base body is configured for axially guiding a rotatable locking bolt, wherein the holding body is configured for coupling a coupling module movable with the locking bolt, wherein the locking bolt is configured for rotating the coupling module by a predetermined angle relative to the base body in order to move the coupling module between a first end position in which the coupling module can be locked in the holding body and a second end position in which the coupling module is unlocked from the holding body, and wherein the base body is configured for rotating the locking bolt in the same direction of rotation regardless of whether the coupling module is to be moved to the first end position or to the second end position. The device has a very compact design, resulting in a shallower installation depth than other access panels or doors. This reduces its footprint, which is particularly advantageous in confined spaces. Furthermore, the mounting points for attaching the device to the components are arranged in such a way that installation is very straightforward compared to other access panels or doors. This is particularly advantageous in confined spaces. An additional advantage of the device is its very simple design. This allows for less complex and therefore more cost-effective production. The device is also designed such that the flap can be moved in a defined direction across the component until it can be removed with minimal risk of damaging the component. This design allows the described device to operate the flap very easily and safely for opening or closing it. Such safe and easy handling of the flap, made possible by the device, reduces the risk of damage to all parts of the building. This is particularly advantageous in confined spaces or under challenging installation conditions, such as on ceilings. These advantages apply not only to, but especially to, more delicate drywall partitions, suspended drywall ceilings, or wooden ceilings. All of this contributes to resource conservation. This device offers a highly advantageous solution for easy and, in particular, improved access to installations in buildings that are intended to be concealed or flush-mounted. These installations include pipes or equipment for building services systems such as heating, electrical, ventilation and / or air conditioning, water systems, and the like. As a result, the described device makes access to and / or maintenance of these installations as convenient, ergonomic, and cost-effective as possible. Furthermore, the device also offers a very advantageous solution for good accessibility in storage space if the storage space is to be covered and / or closed with a flap. Furthermore, the device can help to make it possible to use a flap with a larger flap opening than usual, depending on the installation situation. Advantageous further embodiments of the device are specified in the dependent claims. In one embodiment, the retaining body has two spaced-apart retaining arms for positive locking of the coupling module which can be moved with the locking bolt. In one embodiment, the coupling module movable by the locking bolt has two projections and a receiving element, wherein the projections extend transversely to an axis of the locking bolt and optionally have an inclined surface on their side facing the locking bolt, and wherein the receiving element is arranged between the locking bolt and the two projections. In one embodiment, the base body is designed to guide the rotatable locking bolt in the direction of an axis of the base body and / or an axis of the rotating body. In one embodiment, the base body has a first stop up to which the locking bolt can be moved into the base body for the first end position, wherein the base body has a locking position in which the locking bolt can be locked in its first end position, and wherein the base body has a second stop up to which the locking bolt can be moved out of the base body for the second end position. In one embodiment, the device also has a spring which is mounted between the base body and the locking bolt in such a way that, after a compressive force is applied to the device locked in the first end position, the spring drives a movement of the device into the second end position. The base body and the locking bolt can be designed to accommodate the spring. In one embodiment, the base body has a pot-shaped guide module for receiving the locking bolt, wherein the guide module has a guide groove for axially guiding the rotatable locking bolt. The guide groove can have at least one step which causes the locking bolt to rotate in the same direction every time.

Optionally, the locking bolt has at least one adjusting element for the radial movement of the at least one guide element in the direction of the axis of the locking bolt. In one embodiment, the device is designed for the detachable, in particular tool-free, assembly of the first component and the second component. The first component may be a flap, the second component a building part of a building, and the device is designed for mounting on the flap and for mounting on the building part. The flap can be an access panel, a door, or a window. The flap can be made of a flexible material, in particular sheet metal or plastic, and / or a fibrous material, in particular wood and / or bamboo and / or a fiber composite material. Other possible implementations of the invention also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention. The invention is described in more detail below with reference to the accompanying drawing and an exemplary embodiment. The figures show: Fig. 1 a three-dimensional view of a first end position of a device according to an exemplary embodiment, which is designed for closing or opening a flap; Fig. 2 a three-dimensional view of a second end position of the device of Fig. 1; Fig. 3 a three-dimensional view of the device according to the exemplary embodiment in an intermediate position, which is arranged between the first end position shown in Fig. 1 and the second end position shown in Fig. 2; Fig. 4 an exploded view with partial sectional view of the device according to the exemplary embodiment; Fig. 5 a side view of the device of Fig. 1 in its first end position; Fig. 6 a sectional view along a section line KK shown in Fig. 5; Fig. 7 a side view of the device of Fig. 1.5 in an intermediate position traversed between the first end position of Fig. 5 and a second end position of Fig. 9; Fig. 8 a sectional view along a section line NN shown in Fig. 7; Fig. 9 a side view of the device of Fig. 1 in its second end position; and Fig. 10 a sectional view along a section line JJ shown in Fig. 9. Unless otherwise stated, identical or functionally equivalent components in the figures are provided with the same reference numerals. Fig. 1 shows a first component 1 and a second component 2. A device 3 is mounted on the first and second components 1 and 2. The first component 1 and the second component 2 are spaced apart from each other by a gap 5. The device 3 bridges the gap 5. The device 3 can be mounted on the components 1 and 2 to open or close either the first or second component 1 or 2. As shown in Fig. 1, the device 3 has a base body 30 and a holding body 31. The base body 30 is attached to the second component 2 by fasteners 35. Only one of the fasteners 35 is visible in Fig. 1. The holding body 31 is attached to the first component 1 by fasteners 35. In the example shown in Fig. 1, the fasteners 35 are screws. For example, the first component 1 is a flap. The flap could be, for example, a door or a window. In particular, the flap could be an access panel or access door. The second component 2 is, for example, a part of a building. This could be, for instance, a building wall, a building ceiling, a building floor, or a built-in component of the building. For example, the second component 2 is the outer frame of an access panel or access door. In particular, the built-in component of the building could be a built-in cabinet, a piece of furniture, or part of a staircase. Device 3 enables, for example, the first component 1 to be locked or unlocked on the second component 2. Alternatively, device 3 enables the second component 2 to be locked or unlocked on the first component 1. Locking or unlocking 2 is possible without tools. This is described in more detail below. Fig. 1 shows a first end position of the device 3. In the end position of the device 3 shown in Fig. 1, the device 3 is locked. Consequently, in its first end position, the device 3 holds and / or locks the first component 1 to the second component 2. The first component 1 is mounted on the second component 2. Fig. 2 shows a second end position of the device 3. In the end position of the device 3 shown in Fig. 2, the device 3 is unlocked. Consequently, the device 3 no longer locks the first component 1, so that the first component 1 is detached from the base body 30. The first component 1 is no longer held to the base body 30. Instead, the first component 1 is removable from the second component 2. In Fig. 2, the first component 1 has been disassembled from the second component 2. As shown in Fig. 2, the device 3 also has a locking bolt 32. The locking bolt 32 is held in the base body 30. In the position shown in Fig. 2, the locking bolt 32 is moved out of the base body 30. For this purpose, the locking bolt 32 is rotatable out of the base body 30, particularly starting from the first end position of Fig. 1. Furthermore, the locking bolt 32 is rotatable into the base body 30, particularly starting from the second end position of Fig. 2. In Fig. 2, the locking bolt 32 is arranged at least partially between the base body 30 and the retaining body 31. The locking bolt 32 is movable relative to the base body 30. The locking bolt 32 is movable relative to the retaining body 31. Fig. 3 shows an intermediate position of the device 3. In the intermediate position of Fig. 3, the locking bolt 32 is only partially moved out of or into the base body 30, in particular rotated. Fig. 4 shows the structure of the device 3 in more detail. Here, the device 3 is illustrated in an exploded view. The holding body 31 is also shown in more detail. According to Fig. 4, the retaining body 31 has a coupling module 311, openings 312, and a bend 313. The coupling module 311 has a first retaining arm 311A ​​and a second retaining arm 311B, which are spaced apart from each other. The retaining arms 311A ​​and 311B form a U-shaped opening. The retaining body 31 is adapted to the shape of the component 1, in particular the surface of the component 1, to which the retaining body 31 is to be mounted, in the area of ​​its openings 312. In the example shown in Fig. 4, the retaining body 31 is designed in a plate-like shape. The bend 313 on the component 1 (Fig. 3) provides a predetermined clearance 314 for coupling the retaining body 31 with the locking bolt 32, as described in more detail below. Furthermore, in Fig. 4 the base body 30 is shown partially cut away. Accordingly, the device 3 also has a spring 33, which is partially contained in the base body 30 and partially in the locking bolt 32. In the example of Fig. 1, the spring 33 is a coil spring. According to Fig. 4, the base body 30 has a mounting module 301, a connecting module 302 and a guide module 303. In the example of Fig. 4, the base body 30 is designed as a single piece. The mounting module 301 is adapted to the shape of component 2, in particular to the surface of component 2 to which the mounting module 301 is to be mounted. In the example shown in Fig. 4, the mounting module 301 is designed in a plate-like shape. Thus, the mounting module 301 is adapted to the shape of component 2 on its side facing away from the connecting module 302. In the example shown in Fig. 4, an opening 301A is visible in the mounting module 301. However, in the present embodiment, an opening 301A for a fastening element 35 is arranged in the mounting module 301 on both sides of the connecting module 302. Each of the at least two openings 301A is a through-opening. The openings 301A serve to receive at least one fastening element 35, as shown in more detail in Fig. 5. The connecting module 302 connects the mounting module 301 and the guide module 303. The connecting module 302 provides a stable, and in particular torsionally rigid, connection between the mounting module 301 and the guide module 303. The connecting module 302 is arranged on the mounting module 301 such that each of the openings 301A is designed to be accessible for receiving at least one fastening element 35. Each of the openings 301A is accessible, in particular, in the direction of the axis of the fastening element 35. The guide module 303 is designed as a hollow cylinder. The guide module 303 has a cylinder axis 303A. The guide module 303 is designed to be symmetrical about its axis 303A, with the exception of its at least one guide groove 305. In the example shown in Fig. 4, the hollow cylinder of the guide module 303 is closed at one of its ends. The closed design, or cup shape, is advantageous if the interior of the base body 30, more precisely its guide module 303, is to be protected against contamination. In the guide module 303, at least one guide groove 305 is arranged in its inner wall 304. In the example shown in Fig. 4, the at least one guide groove 305 has at least one step 306. The guide groove 305 is a recess or indentation in the inner wall 304 of the guide module 303. The guide groove is a continuous groove. The guide groove is a groove that runs circumferentially in the inner wall 304. The at least one guide groove 305 is arranged helically in the inner wall 304 of the guide module 303. The at least one guide groove 305 is a helical groove. The at least one guide groove 305 has a predetermined pitch to move the locking bolt 32 axially in the guide module 303, more precisely in the direction of the axis 303A. During the movement, a rotation of the locking bolt 32 around its axis 32A is superimposed with a movement in the direction of its axis 32A. The base body 30, in particular its guide module 303, is designed such that the locking bolt 32 is movable back and forth along the axis 303A of the guide module 303. However, the locking bolt 32 is rotatable only in one direction of rotation DR, in particular by a predetermined angle α, as described in more detail below. In Fig. 4, the direction of rotation DR is, by way of example, a clockwise rotation. The axial movement and the rotational movement of the locking bolt 32 are superimposed. The locking bolt 32 can also be referred to as a (screw) bolt. The guide module 303 also has a recess 307 in its inner wall 304. The recess 307 is located at the closed end of the hollow cylinder of the guide module 303. The recess 307 serves to receive and hold the spring 33 in the guide module 303. Furthermore, the guide module 303 has a first stop 308 in the inner wall 304, up to which the locking bolt 32 can be inserted into the guide module 303. The stop 308 is arranged at the recess 307. In particular, the stop 308 is arranged on the outside of the recess 307, as shown in Fig. 4. Specifically, the stop 308 is arranged at least partially annularly around the recess 307, as shown in Fig. 4. And the guide module 303 has a locking position 308A in the inner wall 304, in which the locking bolt 32 is arranged in its first end position (locked). This is described in more detail below. In addition, the guide module 303 has a second stop 309 in the inner wall 304, up to which the locking bolt 32 can be extended from the guide module 303 in the second end position of Fig. 2. As shown in Fig. 4, the locking bolt 32 is designed as a hollow cylinder. The locking bolt 32 has a cylinder axis 32A, a coupling module 321, guide elements 322, at least one adjusting element 323, and a receiving opening 324. With the exception of its coupling module 321, the locking bolt 32 is designed to be symmetrical about its axis 32A. In Fig. 4, only one guide element 322 is visible on the locking bolt 32. However, two guide elements 322 are arranged on the locking bolt 32. The axis 32A of the locking bolt 32 and the axis 303A of the guide module 303 are preferably mounted on top of each other. In the fully assembled device 3, the axes 32A and 303A coincide. The coupling module 321 is arranged at one end of the locking bolt 32. The coupling module 321 closes the hollow cylinder of the locking bolt 32 at this end. In the example shown in Fig. 4, the guide elements 322 are arranged at the other end of the locking bolt 32. In the example shown in Fig. 4, the adjusting elements 323 are designed as slots. The adjusting elements 323 allow movement of the guide elements 322 over the steps 306 in the guide groove 305. Additionally, the adjusting elements 323 can compensate for a difference between the outer diameter of the locking bolt 32 and the inner diameter of the guide module 303, if necessary. The spring 33 is received in the receiving opening 324 of the locking bolt 32. The coupling module 321 is adapted to the shape of the retaining body 31, in particular its coupling module 311. The coupling module 321 projects out from the locking bolt 32 in the direction of the axis 32A. In the example shown in Fig. 4, the coupling module 321 is T-shaped. The coupling module 321 has two projections 321A and a receiving element 321B. The receiving element 321B has a slightly larger dimension in the axial direction of the axis 32A than the retaining arms 311A, 311B of the retaining body 31. This allows the retaining arms 311A, 311B of the retaining body 31 to be received in the receiving element 321B with some play. The projections 321A extend transversely to the axis 32A, in particular at an angle of approximately 90° to the axis 32A, from the locking bolt 32. The projections 321A are arranged offset by approximately 180° on the locking bolt 32. The cantilevers 321A have an inclined surface on their side facing the locking bolt 32. The inclined surface reduces the distance between the respective cantilever 321A and the locking bolt 32 on one side.The inclined surface thus creates a clamping effect between the projection 321A and the respective retaining arm 311A, 311B when the coupling modules 311, 321 are coupled. The inclined surface also prevents the coupling modules 311, 321 from tilting and / or jamming. This allows the coupling modules 311, 321 to be easily separated again when the locking bolt 32 is to be moved back towards the second end position, shown in Fig. 2 or Fig. 4, or to the position shown in Fig. 3. The projections 321A are movable between the retaining arms 311A, 311B of the holding body 31, in particular until the receiving element 321B is positioned between the retaining arms 311A, 311B. Furthermore, the projections 321A of the coupling module 321 are movable relative to the retaining arms 311A, 311B until the projections 321A are positioned below the retaining arms 311A, 311B in the space 314. In this position, the coupling modules 311, 321 are coupled to each other, so that the device 3 is locked. To decouple and thus unlock the device 3, the projections 321A of the coupling module 321 are moved relative to the retaining arms 311A, 311B until the projections 321A are approximately parallel to the retaining arms 311A, 311B. Locking is achieved by turning, or more precisely, screwing, the locking bolt 32. Since there is some play between the projections 321A and the retaining arms 311A, 311B of the retaining body 31, the projections 321A can be moved relatively freely back and forth between the retaining arms 311A, 311B of the retaining body 31 in order to detach the base body 30 with the locking bolt 32 from the retaining body 31 or to mount it on the retaining body 31. In this way, the coupling modules 311 and 321 can be positively coupled to each other, as described in more detail below. To perform the coupling, the locking bolt 32 also has the guide elements 322, which engage in the guide grooves 305 of the guide module 303 when the device 3 is fully assembled. In the example shown in Fig. 4, the guide elements 322 are arranged at one end of the locking bolt 32. The guide elements 322 project transversely, in particular at approximately 90° to the axis 32A, from the locking bolt 32. The guide elements 322 project from the outer wall of the locking bolt 32. The two guide elements 322 are arranged offset by approximately 180° on the locking bolt 32. When the locking bolt 32 is moved into the base body 30, more precisely its guide module 303, the guide elements 322 engage in the guide groove 305 of the base body 30. The guide elements 322 can be guided in the guide grooves 305 of the guide module 303. The guide elements 322 and the shape of the guide grooves 305 of the guide module 303 are adapted to each other. In the example of Fig. 4, the guide elements 322 are cylindrical, in particular designed as round discs or pins. To assemble the device 3, the spring 33 is inserted into the locking bolt 32 via the receiving opening 324. The spring 33 protrudes partially from the locking bolt 32. As shown in Fig. 4, the spring 33 projects from the locking bolt 32 in the direction of the axis 32A. The locking bolt 32 and the spring 33 arranged therein are then inserted into the base body 30. The locking bolt 32 is held in position in the base body 30, particularly in its guide module 303, by the guide elements 322 and the guide groove 305, as well as by the spring 33 in the receiving opening 307. The adjusting elements 323 can narrow in the circumferential direction of the locking bolt 32, so that the guide elements 322 move towards each other in the radial direction of the locking bolt 32. This allows for compensation of different diameters of guide module 303, more precisely its guide groove 305, and diameter of the locking bolt 32.Thus, a clamping fit between guide module 303 and locking bolt 32 can be achieved, particularly partially. Due to the spring force of spring 33, locking bolt 32 is now in the extended end position, as shown in Fig. 2, as well as in Fig. 9 and Fig. 10. This arrangement corresponds to the state when component 1, which is in particular a flap, is unlocked. Therefore, the arrangement shown in Fig. 2, Fig. 9, and Fig. 10 corresponds to the state of the device 3 when the flap or door is open. When component 1, in particular the flap or door, is closed and thus moved from the position shown in Fig. 2, Fig. 9, and Fig. 10 to the position shown in Fig. 5 as the first end position in a side view and in Fig. 6 as section KK, the locking bolt 32 moves further into the base body 30. The guide elements 322 follow the guide groove 305. The shape of the guide groove 305 causes an axial movement and a clockwise rotational movement on the locking bolt 32. Once the locking bolt 32 has moved into the base body 30 up to the first stop 308 (Fig. 6), the guide elements 322 are moved in the guide groove 305 via the steps 306 shown in Fig. 4. The steps 306 shown in Fig. 4 prevent counterclockwise movement, in particular rotation, of the locking bolt 32. By releasing the component 1, in particular the flap or door, the locking bolt 32 is moved a short distance out of the base body 30 due to the spring force of the spring 33. The locking bolt 32 moves away from the first stop 308 (Fig. 4, Fig. 6) into its position shown in Fig. 5 and Fig. 6, namely the locking position 308A. This corresponds to an axial movement of the locking bolt 32. The guide elements 322 then move the locking bolt 32 further into a rotational movement. In the first end position (locking bolt retracted = locking position 308A), the locking bolt 32 is coupled to the retaining body 31. This secures the coupling module 321 to the retaining arms 311A, 311B. In the state shown in Fig. 5 and Fig. 6, the coupling modules 311, 321 are locked. Fig. 6 shows in the sectional view KK that the spring 33 is almost completely compressed between the locking bolt 32 and the guide module 303 of the base body 32 in the first end position. Thus, the spring 33 is tensioned. The spring 33 exerts a force FS on the recess 307 and the locking bolt 32. Furthermore, the coupling module 311 and the coupling module 321 engage with each other. The coupling modules 311 and 321 couple. Here, the coupling module 321 is arranged in the space 314, which is formed between the retaining body 31 and the component 1. The coupling module 321 is thus arranged under part of the retaining body 31. In Fig. 6, only the retaining arm 311A ​​of the coupling module 311 is visible. To move the device 3 from the end position of Fig. 5 or Fig. 6 back to the end position of Fig. 2 or Fig. 9, Fig. 10, a force FD is applied once more to the component 1, in particular the flap or door. For this purpose, the component 1, in particular the flap or door, can be pressed down with the force FD. This exerts the force FD on the locking bolt 32. The compressive force FD opposes the spring force FS. As a result, the locking bolt 32 is pressed a short distance into the base body 30, in particular the guide module 303 (axial movement), and the guide elements 322 slide over one of the steps 306 (Fig. 4). This also sets the locking bolt 32 into a rotational movement. When the pressure force FD is released again, the spring 33 (Fig. 6) with its spring force FS pushes the locking bolt 32 out of the base body 30, the guide elements 322 follow the guide groove 305. The spring 33 thus drives the device 3, which is locked in the first end position, to move into the second end position after the pressure force FD has acted upon it. This allows the device 3 to be operated without tools. As the locking bolt 32 moves to the second end position, an intermediate position is reached, which is shown as an example in Fig. 7 in a side view and in Fig. 8 in a section NN. The section NN of Fig. 8 is executed along the section line NN shown in Fig. 7. The guide elements 322 follow the guide groove 305 to the second end position (locking bolt 32 extended), which is shown in a side view in Fig. 9 and in a section JJ in Fig. 10. The section JJ of Fig. 10 is executed along the section line JJ shown in Fig. 9. Figures 9 and 10 show how the locking bolt 32 is almost completely removed from the guide module 303 of the base body 32 in the second end position. Thus, the spring 33 is more relaxed than in the first end position of Figure 6. In particular, the spring 33 is relaxed, as shown in Figure 4. Furthermore, in the second end position of Figure 10, the coupling module 311 and the coupling module 321 do not engage with each other. The coupling modules 311 and 321 are decoupled. Here, the coupling module 321 is arranged parallel to the coupling module 311. In the example shown in Figure 10, the coupling module 321 is arranged over part of the retaining body 31. Only the retaining arm 311A ​​of the coupling module 311 is visible in Figure 10. The locking bolt 32 was accordingly rotated again by the predetermined angle α until the second end position of Figs. 9 and 10 was reached. In the example shown, the predetermined angle α is approximately 90°. In the second end position according to Figs. 9 and 10, the coupling module 321 can be moved through the opening (Fig. 4) between the retaining arms 311A, 311B in the retaining body 31. The locking bolt 32 is not held by the retaining body 31. The two end positions, locking bolt retracted in Fig. 5 and Fig. 6 respectively, and locking bolt extended in Fig. 9 and Fig. 10 respectively, are arranged approximately 90° apart from each other. The coupling module 321, located at the lower end of the locking bolt 32, is held in the retaining body 31 by the respective rotation, in particular locked (Fig. 5 and Fig. 6 respectively), or can be moved out through the opening between the retaining arms 311A, 311B of the retaining body 31, in particular unlocked (Fig. 9 and Fig. 10 respectively). Due to the described design of the device 3, its locking bolt 32, in particular its coupling module 321, can be rotated from the first end position of the device 3, shown in Fig. 1, to the second end position of the device 3, shown in Fig. 2, in the same direction of rotation DR (Fig. 4) as from the second end position (Fig. 2) to the first end position (Fig. 1), as previously described with reference to Figs. 4, 5, 6, 7, 8, 9 to 10. In the described example, the direction of rotation DR (Fig. 4) is a clockwise rotation. Of course, it is possible for the direction of rotation DR to be a counterclockwise rotation instead of a clockwise rotation. The transition from the end position illustrated in Figs. 9 and 10 to the end position illustrated in Figs. 5 and 6 is carried out as described previously. The locking bolt 32 always continues to rotate clockwise, regardless of whether the locking bolt 32 moves axially upwards or downwards, as described previously. This allows the device 3 to implement a push / latch rotary locking mechanism, which can also be called a push-lock / rotary locking mechanism. The locking bolt 32 is moved into the base body 30 by pressing against the compressive force FS of the spring 33 in the end position of Fig. 1, which is also illustrated in Fig. 5 and Fig. 6. At the same time, the guide elements 322 cause the locking bolt 32 to rotate by guiding it in the groove 305 (helical groove) in the base body 30. Several steps and guide edges, in particular steps 306, in the groove 305 ensure that only one direction of rotation DR ( Fig. 4 ) is possible, whereby the locking bolt 32 rotates in the base body 30 by the predetermined angle α ( Fig. 4 ), in particular about 90°, and can be locked / unlocked in the respective positions. The spring 33 pushes the locking bolt 32 out of the base body 30. The locking bolt 32 is rotated by the predetermined angle α, in particular about 90°, and thus reaches the end position of Fig. 2, which is also illustrated in Fig. 9 and Fig. 10. In the described embodiment, a retaining body 31 with retaining arms 311A, 311B is used, which is attached to the component 1 (flap, in particular a door). The retaining body 31 unlocks the component 1 in the end position of Fig. 2, which is also illustrated in Figs. 9 and 10, thereby allowing the component 1 (flap, in particular a door) to be opened. By closing the component 1 (flap, in particular a door) and thus pressing on the locking bolt 32 again, it is pressed back into the base body 30 and rotated by the predetermined angle α, in particular approximately 90°. The locking bolt 32 is thus again in the end position of Fig. 1, which is also illustrated in Figs. 5 and 6, and can be locked to the retaining body 31. According to a second embodiment, the guide module 303 of the device 3 is designed as a hollow cylinder open at both ends. The openings at the ends of the hollow cylinder can be of different sizes. Such a design is advantageous, for example, if the base body 30 is to be manufactured with minimal material consumption and is therefore to be particularly lightweight and resource-efficient. The recess 307 can be annular in shape so that counter-pressure can be exerted on the spring 33, as described above in relation to the first embodiment.

Furthermore, the device 3 is constructed in the same way as previously described for the first or second embodiment. According to a fourth embodiment, the locking bolt in device 3 is modified as follows. Accordingly, the locking bolt 32 has smaller dimensions or no adjusting elements 323. The adjusting elements 323 can be reduced in the axial direction of the locking bolt 32 and / or in the circumferential direction of the locking bolt 32 if no compensation is required between the outer diameter of the locking bolt 32 and the inner diameter of the guide module 303. Furthermore, the device 3 is constructed in the same way as previously described for the first, second or third embodiment. According to a fifth embodiment, the locking bolt in device 3 has no adjusting elements 323.

The spring 33 does not have to be designed as a coil spring. Instead, the spring 33 can be designed as a leaf spring, as already described previously with regard to the second embodiment. Additionally or alternatively, the spring 33 can have an elastic body that exhibits a change in length when pressure is applied in one direction. In particular, the elastic body is a rubber-elastic body and / or designed as a gas spring. The locking bolt 32 has at least one guide element 322. If present, the at least one adapting element 323 must be designed accordingly. If at least two guide elements 322 are present, the at least two guide elements 322 can be designed differently.
