[0001] HINGE DEVICE WITH SWIVEL HINGES AND PRE-TENSIONED CONNECTION ELEMENT

[0002] Description

[0003] Technical field

[0004] Exemplary embodiments according to the present invention include hinge devices with pivotable hinge parts and pre-tensioned connecting elements.

[0005] In particular, exemplary embodiments include a hinged closure with a spring-reinforced locking tongue.

[0006] Background of the invention

[0007] Although there are numerous technical designs for hinges, there remains a need for improved concepts that enable the secure and simple locking of hinged components. Current solutions involve elaborate and complex locking mechanisms, which limit potential applications. Furthermore, such complex structures are usually heavy and often require cumbersome handling, which presents disadvantages.

[0008] The object of the present invention is therefore to provide an improved concept for a hinge device which enables a robust and secure locking mechanism, with low complexity and at the same time simple manufacturability and ease of use of the device.

[0009] The problem solved by the invention is addressed by the subject matter of the independent claim. Further developments of the invention are defined in the dependent claims.

[0010] Summary of the invention

[0011] Exemplary embodiments include a hinge device, e.g., a hinge closure, with a first hinge part having a connecting element, e.g., a first housing part with a locking tongue, and a second hinge part, e.g., a second housing part with a housing edge and optionally a recess adjoining the housing edge or a friction contact surface adjoining the housing edge. Furthermore, the first hinge part and the second hinge part are rotatably connected to one another, e.g., by means of a pivot hinge, wherein the first hinge part and the second hinge part are pivotable between a first position in which the connecting element and the second hinge part are releasably engaged with one another and a second position in which the connecting element and the second hinge part are not engaged with one another. The engagement can, for example, be...This involves a releasable locking mechanism, so that the hinge parts are releasably locked together, e.g. by means of a friction contact or e.g. by hooking or snapping the connecting element into a recess or protrusion of the second hinge part.

[0012] Furthermore, the connecting element is pre-tensioned in a starting position. This starting position can be, for example, a position in which the connecting element is aligned with a housing edge of the second hinge part with respect to the pivoting direction. Alternatively, the starting position can be a position in which the connecting element is aligned with respect to the pivoting direction, engaging an inner surface of the second hinge part; the connecting element can be moved into the starting position from a rest position against a restoring force of the pre-tensioning of the connecting element, for example, by means of an external force. The starting position can, in particular, be a rest position of the pre-tensioned connecting element. The pre-tensioning can be set, for example, in the form of a spring-based pre-tension, e.g., with a restoring force in the radial direction of a circular path of the pivotable bearing.

[0013] The connecting element is further designed to be deflected from its initial position by the second hinge part, e.g., a housing edge of the second hinge part, for example in the form of a rounded or beveled housing edge, when the first hinge part and the second hinge part pivot from the second position to the first position, penetrate into the second hinge part and engage the second hinge part, so that the first hinge part and the second hinge part are blocked from each other, i.e., locked together.

[0014] The inventors recognized that a preload on the connecting element, in conjunction with a design of the connecting element and the second hinge part such that the connecting element is deflected from its initial position when pivoting into the first position, contrary to the preload (i.e., deflected radially inwards) in order to engage with the second hinge part, enables a secure, simple, and easy-to-use locking or latching mechanism. The preload on the locking element ensures robust engagement of the first and second hinge parts by means of the connecting element. At the same time, the geometric design of the connecting element, as well as the first and second hinge parts, ensures that this restoring force has little or no effect on the pivoting or locking action.Rotational movement is hindered, so that by twisting between the first and second hinge parts the connecting element can slide smoothly into the second hinge part in order to achieve the blocking effect there.

[0015] The connecting element can achieve a hold within the second hinge part, for example, by snapping into a recess, a snap into an edge, depression or protrusion, or also, for example, by contact with a friction surface (e.g., with sufficient contact pressure, e.g., by means of preload).

[0016] According to exemplary embodiments, the connecting element is bent according to a pivoting direction, e.g., in the direction of a rotational axis about which the first and second hinge parts can pivot, and thus has, for example, a rounded geometry to facilitate deflection from the initial position. The connecting element is bent, for example, in an area facing away from the connection area between the first hinge part and the connecting element.

[0017] Thus, despite a preload strong enough for secure locking, the hinge remains easy to operate. The connecting element can be slid into the second hinge part with minimal effort.

[0018] According to exemplary embodiments, the connecting element is bent according to the pivoting direction, e.g. rounded or chamfered, so that the connecting element can engage in the second hinge part by means of a relative rotational movement of the hinge parts, i.e. e.g. by pivoting the first hinge part and the second hinge part from the second position to the first position, without additional actuation of the connecting element, so that a corresponding bend of the connecting element is formed for this purpose.

[0019] Simply put, the connecting element is designed so that it can slide into the counterpart "by itself" using the rotational movement. "Without additional actuation" here refers, for example, to no additional force being applied to the connecting element in the radial direction of the pivoting motion (i.e., outside of the force required for the rotational movement). This design allows for particularly easy handling of the hinge. In particular, the hinge can be closed by an operator with just one hand.

[0020] According to exemplary embodiments, the connecting element has a change in cross-section corresponding to a pivoting direction in order to facilitate deflection from the initial position, whereby, for example, the cross-section of the connecting element thins or thickens in the direction of a circular path of a relative rotational movement between the first and second hinge part.

[0021] A simplified engagement or sliding into the second hinge part can therefore be achieved, for example, by bending the geometry of the connecting element and / or by changing the cross-section, for example, by changing the thickness of the material of the locking tongue.

[0022] According to exemplary embodiments, the connecting element and the second hinge part are designed such that, when the first hinge part and the second hinge part are pivoted from the second position to the first position, the connecting element, after being deflected from the initial position, at least partially returns to the direction of the initial position, e.g., in order to exert a predetermined force due to the preload of the connecting element in the direction of the second hinge part, e.g., to block the first and second hinge parts against each other, i.e., to lock them against each other.

[0023] In simple terms, overcoming the second hinge part edge can cause a stronger inward bending of the connecting element, so that after overcoming at least part of the connecting element of a certain area, such as an edge, of the second hinge part, the connecting element is at least partially springed back towards the second hinge part according to the preload.

[0024] This allows for easy operation while simultaneously providing a defined and robust engagement of the first and second hinge parts.

[0025] According to exemplary embodiments, the second hinge part has a locking element. The locking element comprises at least one recess, a protrusion (e.g., on an inner surface of the hinge part), and / or a friction surface, such as a friction contact surface. Furthermore, the connecting element is designed to engage the locking element when the hinge part returns, at least partially, to its initial position, for example, by snapping into a recess or protrusion (e.g., a projection), or by establishing frictional contact to block the first and second hinge parts from each other, i.e., to lock them together.

[0026] The use of a locking element enables particularly secure and robust locking of the hinge components relative to each other. Locking elements in the form of recesses allow for easy actuation of the connecting element to release the engagement (e.g., by pressing on the connecting element through the recess). Friction contact surfaces also simplify the operation of the hinge, as no hooking or unhooking is required to actuate it. Furthermore, a desired force for automatic unlocking of the hinge can be set, for example, as a kind of "weak point," so that the hinge can move into the second position when a defined force is applied, thus overcoming static friction.

[0027] According to exemplary embodiments, the locking element comprises a recess, wherein the connecting element is designed to be deflected from its initial position by a housing edge of the second hinge part when the first hinge part and the second hinge part are pivoted from the second position to the first position, to overcome the housing edge, to penetrate into the second hinge part and to snap into the recess, so that the first hinge part and the second hinge part are locked to each other.

[0028] This allows for a robust and easy-to-use locking mechanism, so that by applying pressure to the locking element, e.g. in the form of a locking tongue, the hinge parts can be unlocked in the area of ​​the recess.

[0029] According to exemplary embodiments, the preload of the connecting element in the first position is dimensioned such that engagement of the connecting element in the recess can be released by applying a force to a region of the connecting element located in the recess, in the direction of a rotation axis of the pivoting direction, of at least 1 N (or, for example, at least a minimum value approaching 0 N, i.e., approximately 0 N), of at least 22 N, or of at least 27 N, or of at least 32 N, or of at least 37 N, or of at least 42 N, or of at least 80 N, or, for example, of a force corresponding to the maximum force that a person can apply to a corresponding area of ​​the connecting element (e.g., also more than 80 N, e.g., +10%). The corresponding force to be applied can be material-specific. For example, depending on the material chosen, the force required may be, for example...Other forces may need to be applied, or, according to exemplary embodiments, a specific material can be selected to achieve a certain desired force. The above examples may refer in particular to a design of the connecting element and / or the first hinge part using carbon fiber reinforced polycarbonate, e.g., from a 3D printing process.

[0030] It was recognized that a suitable unlocking force for the inventive concept allows for a good compromise between the security of the locking mechanism and ease of handling using forces that can be applied by humans.

[0031] According to exemplary embodiments, the second hinge part is flattened, rounded or chamfered at least in a partial area, e.g. on a housing edge, to facilitate the deflection of the connecting element from its initial position.

[0032] For example, the sub-area can also be made of a different material compared to another sub-area of ​​the second hinge part, so that, for example, areas with different frictional properties can be provided. For example, a sub-area on a housing edge of the second hinge part can have a low coefficient of friction to facilitate engagement with the connecting element.

[0033] This allows for a good compromise between secure locking and simple handling and operation.

[0034] According to exemplary embodiments, the first hinge part has at least one discrete spring element to increase or generate a preload on the connecting element. The spring element can, for example, be a compression spring, e.g., a coil spring, or a plurality of springs arranged side by side, e.g., between reinforcing ribs.

[0035] Simply put, exemplary embodiments can therefore have discrete springs on the connecting element, for example in the form of a locking tongue. Spring elements allow for simple implementation and manufacturing-adaptable adjustment (e.g., adapting the hinge device for different applications) of the preload. According to exemplary embodiments, the first hinge part has an inner wall, and the at least one discrete spring element is arranged between the inner wall and the connecting element.

[0036] The inner wall increases the rigidity of the hinge mechanism and enables robust force transmission of the spring force. Furthermore, the design with the intermediate wall simplifies the installation of the spring element.

[0037] According to exemplary embodiments, the inner wall and the connecting element have a pin, a recess, and / or a countersink to fasten or fix the at least one discrete spring element. In particular, the inner wall and the connecting element can have a plurality of pins, recesses, or counters to enclose or fasten the spring element on both sides. This allows for easy assembly and robust anchoring of the spring element.

[0038] According to exemplary embodiments, the first hinge part has a spring travel limiter, e.g. in the form of blocking ribs, to limit a radius of movement of the connecting element and / or a compression of the at least one discrete spring element, e.g. to reduce the possible spring travel to a minimum necessary level.

[0039] The spring travel limiter can be designed, for example, by means of the pins used to attach the spring element, or as a separate element, and in particular also as a monolithic continuation of the first or second hinge part. The spring travel limiter prevents overextension of the connecting element, even under excessive force.

[0040] According to exemplary embodiments, the at least one discrete spring element is arranged in a central area, e.g. in a second third of the length starting from the anchoring of the connecting element in the first hinge part, with respect to a longitudinal axis of the connecting element.

[0041] This allows for a good compromise between ease of assembly, a secure locking or blocking force, and the force required to release the two hinge parts. According to exemplary embodiments, the first hinge part has at least one reinforcing rib connected to the connecting element, e.g., in the form of a locking tongue, to ensure an even distribution of bending forces when the second hinge part engages and / or when the connecting element deflects from its initial position. The reinforcing rib can, for example, be monolithically connected to the connecting element. The reinforcing rib can, for example, be formed as part of the connecting element.

[0042] This improves the stiffness of the connecting element and allows for a better distribution of bending forces, which improves the durability of the device.

[0043] According to exemplary embodiments, the first hinge part has a reinforcing structure arranged in a region of the first hinge part where the connecting element is monolithically connected to the hinge part. At least one reinforcing rib is connected to the reinforcing structure, for example, to enable a uniform distribution of bending forces when the second hinge part engages and a predefined preload of the connecting element.

[0044] The reinforcement structure can, for example, take the form of an inner housing wall that is designed antiparallel (e.g., essentially perpendicular) to the connecting element (e.g., to an outer wall of the connecting element). In simpler terms, the reinforcing ribs and tongue can be supported by the reinforcement structure, i.e., an inner wall.

[0045] This improves the robustness, force distribution and durability of the hinge device.

[0046] According to exemplary embodiments, a connection area between the at least one reinforcing rib and the connecting element has a corner radius, e.g. variable, to enable a uniform distribution of bending forces along a longitudinal axis of the connecting element when the second hinge part engages and / or when the connecting element is deflected from its initial position.

[0047] According to exemplary embodiments, the connecting element is a monolithic component of the first hinge part. For example, the connecting element and the first hinge part can form a monolithic unit. In simpler terms, the connecting element can be, for example, "cast in one piece" (without being limited to casting manufacturing processes) with the first hinge part, i.e., cast in one piece with a housing part of the hinge device. Optionally, the connecting element and the first hinge part can be produced, for example, using a 3D printing process.

[0048] This allows for simple manufacturing and, in particular, keeps the number of individual parts of the device low.

[0049] According to exemplary embodiments, the connecting element comprises a section designed to engage with the second hinge part, wherein this section of the connecting element accounts for at least 20% or at least 30% of the total length of the connecting element. For example, this section of the connecting element has an edge for engaging with the second hinge part and subsequently a geometry rounded according to the pivoting direction. For example, the connecting element, i.e., the locking tongue, can be extended with a radius. The length of this section can be adjusted, for example, depending on the material of the connecting element, particularly with regard to the material's flexibility. For materials with greater flexibility, a shorter length can be used.

[0050] According to exemplary embodiments, the first and second hinge parts are mounted by means of a pivot hinge, wherein the first and second hinge parts are arranged to interlock in a region of the pivot hinge, with, for example, a hinge bushing being formed through both interlocking hinge parts. Furthermore, a height difference and / or a contact force between the first and second hinge parts in the region of the pivot hinge is optionally adjustable in order to dampen the pivoting between the first and second hinge parts.

[0051] A friction effect in the pivot hinge can therefore be adjusted. The friction in the hinge's "thread" can thus be adjusted, for example, increased or decreased. This adjustment can be achieved, for instance, by tightening or loosening a screw on the pivot hinge. Some designs optionally feature a conical hinge guide, whereby the further the hinge is rotated, the greater the friction becomes, thus fixing the elements (e.g., the first and second hinge parts relative to each other) in place (or at least increasing their friction).

[0052] According to exemplary embodiments, the first and second hinge parts are mounted by means of a pivot hinge, wherein the first and second hinge parts each have an inner wall structure, the inner wall structure of the first hinge part, for example, comprising the inner wall for attaching the at least one discrete spring element. The inner wall structures of the first and second hinge parts are aligned with each other in the first position to provide a defined channel between the pivot hinge and the connecting element, i.e., for example, a cross-sectional area that is not occupied by the resilient area of ​​the connecting element or the pivot point of the hinge device.

[0053] The channel can be provided, for example, in the form of a cable duct, a conduit, or a channel for liquids. This allows for the efficient integration of other components, and especially supply lines, such as power cables, despite the hinge's rotatability.

[0054] According to exemplary embodiments, the first and second hinge part each have a membrane, e.g. a sealing membrane, sealing a cross-section of the channel, for example with cable passage through the membrane, in order to seal a channel section at a contact surface between the first and second hinge part in the first position against further sections of the channel in the first and second hinge part, e.g. with regard to dust and / or liquids.

[0055] According to exemplary embodiments, the hinge device has a sealing device on a contact surface between the first and second hinge part in the first position, which is designed to seal the channel along the contact surface in the first position, e.g. with regard to dust and / or liquids.

[0056] The membrane can therefore be, for example, a surface arranged within a cross-sectional area of ​​the first and / or second hinge part, which enables a seal, whereas the sealing device can be an element arranged on edges or edge areas (e.g. housing edges) of the first and / or second hinge part.

[0057] According to exemplary embodiments, the first and second hinge parts each have sealing lips on the contact surface between the first and second hinge parts in the first position, which are designed to interlock in the first position and seal the channel along the contact surface, e.g. with regard to dust and / or liquids.

[0058] Interlocking sealing lips enable easy sealing while allowing the hinge parts to rotate. The sealing lips can also be designed to provide a certain degree of friction to assist in locking the first and second hinge parts. Thus, the sealing lips, together with the connecting element, enable a synergistic locking effect.

[0059] According to exemplary embodiments, the connecting element has a colored marking to indicate that the first position has been reached, and / or the connecting element and the second hinge part are designed to generate an acoustic signal when the first position is reached, e.g., by means of the preload of the connecting element and the choice of material for the connecting element and the second hinge part. Alternatively or additionally, the connecting element and the second hinge part are designed to generate a haptic signal when the first position has been reached.

[0060] The haptic or acoustic feedback can be designed, for example, as a spring-back or snapping sound of the connecting element, such as when it engages in a recess. The acoustic signal can be, for example, a click sound when the connecting element, such as the tongue, engages in the locking mechanism, as well as a raised section of the tongue above the engagement point. The visual feedback can be designed, for example, by marking certain areas of the raised section of the tongue, e.g., red / green. If, for example, green is visible, the hinge, or the connecting element, such as a latch, is locked.

[0061] This allows for safer and easier operation of the hinge device.

[0082] Detailed description of the embodiments according to the figures

[0083] Before exemplary embodiments of the present invention are explained in detail below with reference to the drawings, it should be noted that identical, functionally equivalent or equivalent elements, objects and / or structures in the different figures are provided with the same or similar reference numerals, so that the description of these elements shown in different exemplary embodiments is interchangeable or can be applied to one another.

[0084] Fig. 1 shows a schematic view of a hinge device with optional features according to exemplary embodiments of the invention. Fig. 1 shows a hinge device 100 with a first hinge part 110 with a connecting element 111 and a second hinge part 120, wherein the first hinge part and the second hinge part are rotatably connected to each other. As an example, a connection of the first and second hinge parts by means of a pivot hinge 130 is shown, such that the first and second hinge parts can be pivoted relative to each other, see 131.

[0085] The first hinge part 1 10 and the second hinge part 120 are pivotable 131 between a first position in which the connecting element 11 1 and the second hinge part 120 are detachably engaged with each other (see Fig. 2), and a second position in which the connecting element and the second hinge part are not engaged with each other (shown in Fig. 1) (where arrow 131 shows an exemplary transition from the second to the first position).

[0086] The connecting element 11 1 is pre-tensioned in an initial position and the connecting element 1 11 is designed to be deflected from the initial position by the second hinge part when the first hinge part 110 and the second hinge part 120 are pivoted from the second position to the first position, to penetrate into the second hinge part 120 (so that the connecting element penetrates the second hinge part on an inside side of the second hinge part) and to engage the second hinge part tz, so that the first hinge part and the second hinge part are blocked relative to each other.

[0087] As an optional feature, Fig. 1 shows an embodiment of the engagement by means of a locking element 150 in the form of a recess 122, such that the connecting element snaps into the recess in the second position, thus locking the hinge parts relative to each other. It should be noted that, just like the embodiment of the locking element, the corresponding embodiment of the connecting element in Fig. 1 is to be understood as an optional example to facilitate a simple understanding of the invention. Any edges, radii, and length ratios in Fig. 1 are therefore optional.

[0088] Before discussing further optional configurations of the intervention in the context of Fig. 5, the initial situation of the connecting element 1 11 will first be explained in more detail.

[0089] Fig. 3 shows schematic views (in the -z direction corresponding to Fig. 1) of a region 140 (see Fig. 1) in which, during the transition from the second to the first position, the connecting element 1 11 penetrates into the second hinge part 120 in order to engage it, according to embodiments of the present invention.

[0090] As shown in Fig. 3a), the initial position can optionally be a rest position of the pre-tensioned connecting element 1 11, so that when transitioning from the second to the first position for engagement, a force F must be applied to the connecting element 1 11 to allow it to overcome an outer edge 121 of the second hinge part, so that the connecting element 11 1 can slide into an inner side of the second hinge part 120.

[0091] Alternatively, as shown in Fig. 3b), the initial position can, for example, be an alignment between the second hinge part 120 and the connecting element. Optionally, the edge 121 can be chamfered, for example, to allow the edge to be overcome, for example, without any further applied force F, e.g., solely due to the rotational movement 131.

[0092] As a further alternative example, Fig. 3c) shows an initial position in which the connecting element 111 is less biased towards an outer side of the second hinge part 120 compared to Fig. 3a), so that the connecting element 111 can slide directly into an inner side of the second hinge part when rotated 131. The initial positions shown in Fig. 3b) or 3c) can, for example, be the rest position of the connecting element 111, or with a small force F it could be moved from the rest position (e.g., a rest position corresponding to Fig. 3a)) to the initial position corresponding to Fig. 3b) or Fig. 3c) (e.g., with only slight pressure F on the connecting element 111 when turning it together).

[0093] In particular, due to the bending of the connecting element 111 and the resulting initial or rest position, engagement can only be achieved by means of a rotational movement, despite preload and without additional actuation with a force F.

[0094] It should also be noted again that exemplary embodiments are not limited to the geometry of the connecting element shown in Fig. 1. Changes in the cross-section of the connecting element or rounded geometries as shown in Fig. 1 are merely optional. Fig. 4 shows schematic views corresponding to Fig. 3, in which the connecting element 41 1 (corresponding to element 11 1 in Fig. 1) is designed without bending or cross-sectional changes. The situations in Fig. 4a) and 4b) correspond, for example, to the configurations in Fig. 3a) and 3b). Thus, any combination of initial position and geometry of the connecting element is possible for exemplary embodiments.

[0095] In this sense, it is pointed out once again that the intervention shown in Fig. 1 by means of a recess and the special design of the connecting element is to be understood as optional.

[0096] Fig. 5 shows schematic views of optional embodiments of a corresponding engagement between the first and second hinge parts according to exemplary embodiments. Fig. 5a) shows a schematic side view (left, in the y-direction corresponding to Fig. 1) of a partial area 520 of the second hinge part 120 with recess 122, as well as a schematic cross-sectional view (right, in the -x-direction corresponding to Fig. 1). Fig. 5b shows a schematic side view (left, in the y-direction corresponding to Fig. 1) and a schematic cross-sectional view (right, in the -x-direction corresponding to Fig. 1) of an alternative embodiment of a partial area 520b of a second hinge part, which has a projection 550b on an inner side of the second hinge part into which a correspondingly designed counter-geometry of the connecting element 111, e.g., an edge, can engage or snap.Figure 5c) shows a schematic side view (left, in y-direction according to Fig. 1) and a schematic cross-sectional view (right, in -x-direction according to Fig. 1)) of a further alternative embodiment of a partial area 520c of a second hinge part, which has a friction contact surface 550c on an inner side of the second hinge part in order to establish a frictional connection with the connecting element, which optionally also has a friction contact surface, for blocking the first and second hinge part.

[0097] The planar integration of the friction surface 550c is to be understood as an example; the friction surface 550c can also be designed as a raised or recessed area. The same applies accordingly to the raised area 550b, which can also be designed as a recessed area.

[0098] In other words, Fig. 5 shows different embodiments of the optional blocking element 150, as shown in Fig. 1.

[0099] It should be noted that a locking element 150, according to exemplary embodiments, can also have combinations of recesses, protrusions, depressions, and friction surfaces. For example, a recess 122, as shown in Fig. 1, can be present to simplify the actuation of the connecting element 111, with the actual locking mechanism, such as a friction surface, a protrusion, or a depression for engagement, being arranged in the area of ​​the second hinge part between the recess 122 and the edge 121. Thus, the connecting element 111 can, for example, also be designed without an edge for engagement in the recess 122, or it can have such an edge (see, for example, Fig. 10) as a redundant locking mechanism, for example, in addition to a friction surface in the area of ​​the second hinge part between the recess 122 and the edge 121.The connecting element 1 11 can then have corresponding counter-elements (such as an edge for engagement in a recess, or a counter-friction surface) at the appropriate location (i.e., for blocking in the first position).

[0100] Fig. 6 shows a schematic sectional view of a hinge device, e.g. in the form of a hinge closure, with a spring-reinforced locking tongue in a first position, according to embodiments of the present invention.

[0101] In addition to the elements discussed in the context of Fig. 1, the hinge device 600 has an optional, discrete spring element 610, which enables an increase in the preload of the connecting element 11. Furthermore, the hinge device 600 has an optional inner wall 620, wherein the discrete spring element is attached between the inner wall 620 and the connecting element 11. The hinge device 600 also has inner wall structures and an optional channel, but these are discussed in detail in the context of Fig. 16.

[0102] In general, the pivot point of the hinge 130 can be located on any side of the hinge device, e.g., 100, 600. To ensure that a corresponding optional lock on the opposite side easily engages in the optional locking recess 122, it is optionally extended with the corresponding radius 112. The connecting element 111, for example, in the form of a locking tongue, is reinforced on the reverse side with a spring element 610 or, optionally, several springs. These springs press the locking tongue 111 outwards with a force, e.g., a constant force. Inserting the locking tongue 111 into the locking recess 122 when closing is simplified, among other things, by the fact that the locking tongue has been extended, thus allowing the one or more springs 610 to be compressed more easily. This reduces the force required by the user to close the device.Once the tongue 11 1 is fully inserted and engaged, the springs 610 prevent easy unintentional opening or opening by applying force to the hinge. To open, the locking tongue 1 11 can be pressed, which compresses the springs and allows the hinge to be opened and moved.

[0103] The embodiment of the connecting element 11 1 shown in Fig. 6 with radius-shaped geometry 112 in an area which is designed to engage in the recess 122 and the adjoining edge for creating the locking mechanism thus enables secure blocking with easy release.

[0104] Fig. 7 shows a schematic view of a hinge device 700 in a second position, which, in comparison to the device 600, has several discrete spring elements 610.

[0105] Regarding exemplary embodiments, it should be noted generally that corresponding hinges can be manufactured as assemblies with 3D-printed main parts made of carbon fiber reinforced polycarbonate, and the following explanations refer specifically to this material selection (e.g., regarding parameters such as the force to be applied, the length of the connecting element, and / or the positioning of the springs). However, exemplary embodiments also include alternative designs with other materials; in particular, an alternative printing material for the main parts is possible, for example, with slightly modified geometry or different springs, either without problems or at least without major issues or modifications.

[0106] Fig. 8 shows a schematic exploded view of the hinge device 700 from Fig. 7. A parts list for the device 700 includes, for example, the elements shown: hinge part 1, 110, hinge part 2, 120, threaded insert 810 (e.g., M4x6x4 threaded insert), screw 820 (e.g., DIN 912 M4x35), and discrete spring elements 610, e.g., (compression spring 0.7x7x20 mm (here, 2 pieces)).

[0107] In the context of Figs. 9 and 10, optional details regarding the ratio of the length of the connecting element 111, i.e., the “tongue”, to the radius of the hinge are explained below.

[0108] Fig. 9 shows a schematic view of the hinge device of Fig. 1 with an additional illustration of an exemplary length of the connecting element 11 1 according to exemplary embodiments. The length of the connecting element can be adjusted, in particular depending on the material thickness and the force required to release the engagement.

[0109] As shown in Fig. 9, the connecting element, e.g. the tongue, e.g. the entire spring-loaded area of ​​the locking hook (as an example of the connecting element), can have a length (e.g. between pivot point and outermost edge facing the second hinge part 120) of 77.5 mm in order to provide sufficient clearance (e.g. with regard to force and / or actuation area) for releasing the locking hook with the necessary material thickness.

[0110] Fig. 10 shows a schematic view (in the -z direction corresponding to Fig. 1) of an optional embodiment of the second hinge part and the connecting element in a contact area according to exemplary embodiments. As an example, the connecting element 111 is designed as a locking hook and has an edge 1020 and a region 1030 in which a protrusion or edge of a recess of the second hinge part can engage in the second position (indicated here in Fig. 10 for illustration, even though the connecting element is not yet engaged with the second hinge part 120). The region shown in Fig. 10 can, for example, correspond to region 140 from Fig. 1. As shown, the edge 121 of the second hinge part can optionally be chamfered or flattened to facilitate engagement.

[0111] As shown in Fig. 10, optionally a radius 121 on the latching hook itself can be chosen such that during the folding movement 131, the hook in the counterpart 120, due to its widening geometry (widening from the end 1010 facing the second hinge part to the edge 1020), pushes the entire tongue 11 1 back so far that a latching into the area behind the hook, 1030, can take place.

[0112] Thus, when the connecting element snaps into place, it can at least partially return to its original position and engage the blocking element, in this case the recess or an edge of the recess.

[0113] The connecting element 1 11 can therefore be bent according to a pivoting direction 131 and additionally or alternatively have a change in cross-section, here a thickening starting from the end 1010.

[0114] It should be noted that a suitable design of the connecting element for easily overcoming edge 121 can be achieved from any combination of geometric changes such as cross-sectional changes, flattening, chamfering, bending and rounding.

[0115] For example, an outer surface of the connecting element can be designed such that the outer surface of the connecting element at the end 1010 lies in a radial direction within a circular path parallel to the pivoting movement and a subsequent section of the connecting element in the direction of a connection point with the remaining part of the first hinge part lies in a radial direction outside this circular path parallel to the pivoting movement.

[0116] In other words, the connecting element can become thicker or wider in the radial direction, i.e., away from the axis of rotation (in the plane shown in Fig. 10, e.g., xy-planes according to Fig. 1)-

[0117] The end 1010 can therefore, for example, be located closer to the axis of rotation of the pivoting movement than a subsequent outer surface of the connecting element. Regarding the definition of a spring force range, e.g., of the connecting element, optionally with discrete spring elements, such as elements 610, and also the design of the axis of rotation of the connecting element, e.g., the "tongue" axis of rotation, e.g., with regard to strength, implementation, and any modifications, further aspects will be discussed below according to exemplary embodiments.

[0118] It should be noted that, in general, the spring force can be composed of at least two factors according to the exemplary embodiments:

[0119] • The material in conjunction with the geometry of the resilient (i.e., pre-stressed) area of ​​the first hinge part (where, for example, to achieve a uniformly distributed bending of the resilient area and to prevent overloading due to bending in certain areas of the connecting element, e.g., the tongue, this can optionally have a geometry adapted by one or more, e.g., three, continuous ribs and / or variable corner radii (see Figs. 12, 1250 below) to better distribute the forces over the entire length. By adjusting the wall thickness and varying the radii in the connection area, the tongue / resilient area can be modified)

[0120] • one or more, e.g. two additional spring elements (e.g. compression springs (0.7x7x20mm)) to increase the resistance to releasing the hinge

[0121] For example, a necessary force (e.g., of at least 32N) can thus be set on the intended area (e.g., area 11 10, see Fig. 1 1 below) in order to push back the connecting element (e.g., the locking hook) far enough so that the hinge can be opened.

[0122] Fig. 11 shows a schematic view of the hinge device 100 from Fig. 2 with an additionally highlighted area 1110 for releasing the engagement, according to exemplary embodiments. Area 1110 can, in particular, also have a color highlight to indicate that the second position has been reached, i.e., for example, a secure locking position.

[0123] Fig. 12 shows a schematic view of a partial area of ​​a first hinge part with connecting element from an inside view of the first hinge part, according to exemplary embodiments of the invention. Fig. 12 shows in particular the previously discussed influencing factors for the preload and bending stiffness of the connecting element 111. Fig. 12 shows a sectional view of the first hinge part 110 viewed from inside the hinge part, wherein the hinge part 110 has additional optional features. For one thing, the connecting element 111 optionally has pins 1210, which serve to fasten discrete spring elements. As shown in Fig. 12, the pins 1210 and thus also any discrete spring elements can be arranged in a central area of ​​the connecting element with respect to a longitudinal axis of the connecting element, e.g.,between 50% and 70% of the total length L of the connecting element, starting from a connection point of the connecting element with the first hinge part.

[0124] The fasteners can, for example, be arranged at a transition area of ​​the connecting element between a region located within the first hinge part and a region designed to engage the second hinge part, but still within the region located within the first hinge part, i.e., here shortly before the start of the section highlighted with 1240. This allows for a good compromise between ease of assembly, preload, and ease of release.

[0125] As a further optional feature, the connecting element 1 11 has reinforcing ribs 1 120, shown in Fig. 12 as ribs running along the connecting element 111 to enable a uniform distribution of forces along the connecting element 1 11.

[0126] As a further optional feature, the first hinge part 110 has a reinforcing structure 1230, which serves as the basis for the stable connection of the connecting element 111 with the rest of the first hinge part 110. The reinforcing ribs 1220 and the reinforcing structure 1230 are connected together as an example and form a reinforcement of the anchoring of the connecting element 111 to the rest of the first hinge part 110.

[0127] As a further optional feature, the connecting element 1 11 has a rounded geometry 1250 in the transition areas 1230 between the reinforcing ribs 1220 and an outer wall structure of the connecting element 1 11. Such variable corner radii 1250 also improve the distribution of bending forces on the overall structure of the connecting element 1 11.

[0128] Such corner radii 1250 can also be implemented at the transition from the reinforcing ribs to the reinforcing structure 1230 or from the outer wall structure of the connecting element 111 to the reinforcing structure 1230. As shown in Fig. 12, the connecting element 111 can optionally be a monolithically formed section of the first hinge part 110. The section 1240, which is designed to engage with the second hinge part, can, for example, comprise at least 20%, 25%, 30%, or 35% of the total length L of the connecting element.

[0129] Fig. 13 shows a schematic view of the section of the first hinge part from Fig. 12 with the connecting element, from an outside perspective of the first hinge part, according to exemplary embodiments. In Fig. 13, the central area for the arrangement of the fastenings for discrete spring elements is highlighted again. With an optional overall length of the connecting element 111, as shown, for example, in Fig. 9, the fastenings, i.e., as shown, for example, pins 1210, can be arranged at a distance of 41 mm (e.g., optionally + / - 10 mm) from a connection area between the connecting element 111 and the remaining first hinge part 110. As shown in Fig. 13 and discussed previously, the connecting element 111 can be monolithically connected to the first hinge part 110, i.e., connecting element 111 and first hinge part 110 are a single “inseparable” (e.g., non-destructively inseparable) component made of the same material (e.g.,(manufactured using a common printing process). According to Fig. 13, a corresponding device has, as an example, two mandrels 1220 and thus two discrete spring elements.

[0130] The two spring elements, for example in the form of compression springs, are positioned in the middle of the spring area. This represents a compromise between maximum leverage and ease of assembly. In this position, they cannot be removed by the end user without tools.

[0131] Reference is made here to Fig. 14. Fig. 14 shows a schematic view of a first hinge part with optional inner wall and optional discrete spring elements according to embodiments of the invention. Fig. 14 shows a first hinge part 1 10 with connecting element 11 1 , as well as optional pins 1120 and optional discrete spring elements 610 fastened by means of the pins 1220.

[0132] As a further optional feature, the first hinge part 1 10 has an inner wall 620, which also has pins 1220. It should be noted that corresponding fastenings for the spring elements 610 can also be provided on only one side, i.e., either on the side of the inner wall 620 or on the side of the connecting element 1 11. For a particularly robust fastening of the spring elements 610 tz, they can be fastened on both sides between the inner wall 620 and the connecting element 1 11 by means of the fastenings 1220, as shown in Fig. 14, for example, so that the springs 610 are clamped under guidance by means of the pins 1220.

[0133] As a further optional feature, the first hinge part 1 10 has a spring travel limiter 1420 to restrict the radius of movement of the connecting element 111 and / or the compression of the springs 610. The spring travel limiter can be implemented by means of individual stops as shown in Fig. 14, or alternatively the pins 1220 can also serve as spring travel limiters.

[0134] In summary, the spring elements in Fig. 14 (e.g., in the form of the compression springs shown) are optionally held on both sides by mandrels 1220. In the assembly shown, they can be installed using special tools. If required, the number of springs 610 can be increased by inserting additional mandrels 1220 in the area next to the existing ones, thus allowing the mounting of multiple springs, e.g., compression springs. To prevent overloading of the material due to bending, spring travel limiters 1420 in the form of two locking ribs are incorporated, reducing the possible spring travel 1430 to the minimum necessary level.

[0135] Inventive embodiments of the spring positions, the number of springs, the fastening of the springs, as well as the strength, implementation and modifications of the axis of rotation of the connecting element can therefore be set in consideration of the influences discussed in the context of Figs. 13 and 14.

[0136] In the following, we refer to Fig. 15. Fig. 15 shows a schematic view of a pivot hinge and an interlocking arrangement of a first and second hinge part in the area of ​​the pivot hinge according to exemplary embodiments.

[0137] As shown in Fig. 15, the first and second hinge parts can be mounted by means of a pivot hinge 130, wherein the first and second hinge parts are arranged interlocking in a region of the pivot hinge, and wherein a height difference and / or a contact force between the first and second hinge parts in the region of the pivot hinge can optionally be adjusted to dampen the pivoting between the first and second hinge parts. For example, the screw 820 can be tightened more firmly to achieve a higher contact force and thus friction between the first and second hinge parts. This increases, for example, the friction in the "thread". However, according to alternative embodiments, it is also possible to have a conical hinge guide. That is, the further the hinge is rotated, the greater the friction becomes and the elements are fixed.

[0138] As a concrete example, at the pivot point of the hinge 130, both hinge parts can be connected by a DIN 912 M4x35 screw 820. This is received, for example, in hinge part 1 by an M4x6x4 threaded bushing 810.

[0139] A friction effect is not necessarily intended or required according to the embodiments, but can be generated, as explained, by modifying the height difference between hinge part 1 and hinge part 2. In other words, a corresponding friction effect and its adjustability are optional for exemplary embodiments.

[0140] Reference is made below to Fig. 16. Fig. 16 shows a schematic view of a hinge device 1600 with an optional channel highlighted according to exemplary embodiments. The hinge device shown in Fig. 16 includes the optional pivot hinge 130 for providing pivotability of the first and second hinge parts 110, 120. As further optional features, the first and second hinge parts each include inner wall structures 1610, 1620, which are aligned with each other in the first position, so that a defined channel 1630 is provided. As an optional feature, the inner wall structure 1610 corresponds to the inner wall 620 discussed previously. The inner wall structure 1610 can thus be designed for attaching spring elements and simultaneously for defining a channel 1630. As shown in Fig.However, 16 embodiments are not limited to the use of spring elements; the preload can also be achieved solely by means of the design of the connecting element 1 1.

[0141] In other words, the cross-sectional area, e.g. 1630, which is not occupied by the spring area or the pivot point of the hinge, can be used, for example, for cable or conduit routing.

[0142] Fig. 17 shows a schematic view of the hinge device from Fig. 16 with indicated positions for optional membranes according to exemplary embodiments. Fig. 17 shows exemplary sections 1710 along the channel 1630 in which membranes can optionally be arranged, with which a cross-section of the channel 1630 can be sealed, so that a channel section at a contact surface between the first and second hinge part in the first position (i.e., the area of ​​the channel 1630 between the two membrane positions 1710) is sealed against further sections of the channel in the first and second hinge part.

[0143] As an example, a possible position for a cable 1720 (e.g., also a hose, e.g., a hydraulic connection) is shown, whereby membranes may optionally have cable glands. It should be noted that the positions of the sealing membranes 1710 are to be considered exemplary.

[0144] In summary, the cross-sectional area not occupied by the spring section or the pivot point of the hinge can be used for cable or conduit routing (see, for example, cable 1720) and, if necessary, sealed by a sealing membrane (see, for example, positions 1710), optionally with a cable entry on each side. It should be noted again that the membrane positions shown in Fig. 17 are optional.

[0145] Figures 16 and 17 show, for example, cable duct sections of hinge devices according to exemplary embodiments.

[0146] Fig. 18 shows a schematic view of a hinge device in the first position with an optional sealing device according to exemplary embodiments. The hinge device has a sealing device 1810 on a contact surface between the first and second hinge parts in the first position, which is designed to seal the channel along the contact surface in the first position. As an optional feature, the sealing device has sealing lips 1820, 1830 which interlock in the first position to seal the channel along the contact surface between the first and second hinge parts.

[0147] With further modification of the contact between hinge parts 1 and 2, as shown, for example, in Fig. 18, liquids can optionally also be conveyed through the cable channel. For this purpose, as shown in Fig. 18, sealing lips 1820 and 1830 can be attached to both sides, which interlock when folded and thus seal the area.

[0148] As discussed in the context of the figures above, some embodiments involve a pivot hinge which, compared to conventional solutions, is equipped with a locking tongue that is reinforced with one or more return springs and curved in the area of ​​a locking recess. The curvature of the locking tongue, for example in the form of an extension corresponding to the radius of the pivot hinge, is particularly suitable for compensating for the effect that, when the pivot hinge is closed, the springs push the locking tongue so far outwards that the locking tongue cannot engage within the counterpart, i.e., the second hinge part, but instead protrudes beyond an outer surface of the counterpart.

[0149] The locking mechanism can be designed, for example, to withstand forces of 10-20 kg tensile force, while still allowing a person to release the lock by hand.

[0150] Materials for the first and second hinge parts can include plastics, fiber composites or carbon-reinforced plastics, as well as metallic materials, e.g., also from printing processes.

[0151] According to exemplary embodiments, no springs or between one and three springs can be used to provide sufficient restoring force for reliable locking.

[0152] Exemplary embodiments with an arrangement of the springs in a central area of ​​the connecting element create a good compromise between an arrangement far back in the device, where the spring travel is small, and an arrangement further forward in the device, where the spring might possibly hinder the locking mechanism itself.

[0153] Metals or plastics can be used for the springs. In particular, suitable holders, such as the previously discussed mandrels, can offer advantages in the manufacture of the device, allowing a spring, for example, to be compressed during assembly and inserted into opposing holder mechanisms, whereupon the spring unfolds and thus locks into the holder.

[0154] The swivel hinge can, for example, be a bronze part baked into plastic, such as a bronze bushing into which a screw engages.

[0155] The locking tongue is optionally cast as one piece with the associated housing part to ensure easy manufacturing.

[0156] The influence of environmental factors can be addressed, for example, by selecting the appropriate polymer for the first and second hinge parts or by applying a coating, for example, to prevent the plastic of the first and second hinge parts from hardening due to UV radiation.

[0157] The device can also be used for foldable connectors, allowing them to be folded to minimize their size, for example, during transport. When unfolded, a clicking sound can be heard, and the locking tongue can be color-coded to reliably indicate successful locking. Unlike conventional solutions, this eliminates the need for a special sensor to detect a secure lock.

[0158] A locking mechanism according to the invention can, for example, also provide haptic feedback, e.g. by means of a "rebound" or "snap" when engaging due to the preload.

[0159] As shown in the previously discussed figures, exemplary embodiments can include a central wall, i.e., an inner wall, which can be designed to provide a cable duct within the device. This duct can be made water- and / or dust-proof, for example, by means of sleeves and / or seals. Cables can thus be routed over the pivot hinge. The device can therefore form an infrastructural guidance system or be part thereof.

[0160] The cables can be attached, in particular, essentially loosely or at least movably, within the two hinge parts in order to minimize stress on the cables due to changes in length when the hinge is opened due to a change in radius.

[0161] The simple design of the device, for example without extra locking mechanisms, makes it possible to achieve a low weight of the resulting device.

[0162] All the materials, environmental influences, electrical properties and optical properties listed herein are to be regarded as examples and not as exhaustive.

[0163] Although some aspects have been described in connection with a device, it is understood that these aspects also represent a description of the corresponding process, such as a manufacturing process, so that a block or component of a device can also be understood as a corresponding process step or as a feature of a process step.
