Abstract
Description
[0001] The invention relates to a webbing fastener according to the preamble of claim 1.
[0002] Such a webbing fastener has a connecting device comprising a first connecting part having a first base body and at least one engagement projection rigidly arranged on the first base body. The connecting device also comprises a second connecting part, which can be attached to the first connecting part in a closing direction and is connected to a strap. The second connecting part has a second base body with an engagement section rigidly arranged on the second base body. The engagement section can be brought into engagement with the at least one engagement projection of the first connecting part along an engagement direction different from the closing direction, for example, transverse or oblique to the closing direction, such that in a connected position of the first connecting part and the second connecting part, the engagement section is in engagement with the at least one engagement projection of the first connecting part.The first connecting part has a first magnetic device, and the second connecting part has a second magnetic device. The first and second magnetic devices interact magnetically along the closing direction to assist in the alignment of the first and second connecting parts.
[0003] In the connecting device, one or more engagement projections are rigidly formed on the first base body of the first connecting part. The second connecting part can be engaged with the at least one rigid engagement projection by bringing a section of the second connecting part into engagement with the at least one engagement projection of the first connecting part. The first and second connecting parts are brought together along a closing direction, along which magnetic elements of the connecting parts provide a magnetic attraction force, so that the connecting parts are drawn towards each other along the closing direction. In contrast, the engagement of the section of the second connecting part with the at least one engagement projection of the first connecting part occurs along a direction of engagement that is perpendicular to the closing direction.In the connected position, the engagement section engages with at least one engagement projection in a form-fitting or force-fit manner, so that the connecting parts are held together.
[0004] The fact that the direction of engagement differs from the direction of closing means, in this context, that the direction of engagement is perpendicular or at an oblique angle to the direction of closing. The direction of engagement is not necessarily exactly perpendicular to the direction of closing, but may extend at an oblique angle to it. However, the direction of engagement is not along the direction of closing, and in particular, not opposite to the direction of closing.
[0005] In a locking device known from EP 3 616 553 A1 for the detachable connection of two parts, a first connecting part can be attached to a second connecting part to join the connecting parts together. A shoelace is arranged on one of the connecting parts, which can be tightened by connecting the connecting parts together.
[0006] From EP 3 192 388 B1, a locking device is known in which a first connecting part has a rigid engagement projection and can be connected to a second connecting part. A strap is adjustably arranged on the second connecting part.
[0007] Document WO2019 / 186665A1 discloses a webbing fastener with the features of the preamble of claim 1.
[0008] With a connecting device of the aforementioned type, it is generally desirable to enable the connecting parts to be joined in a simple, convenient, and tactilely pleasing manner for the user. The connection should preferably be tolerant of positional variations, even if the connecting parts are not positioned precisely against each other. A secure and load-bearing connection should be created when the connecting parts are joined.
[0009] The object of the present invention is to provide a connecting device in which the connecting parts can be attached to each other in a simple, convenient manner and provide a secure, resilient hold on each other in a connected position.
[0010] This problem is solved by an object having the features of claim 1.
[0011] Accordingly, the second connecting part is rotatable in the connected position about the closing direction relative to the first connecting part, whereby the engagement of the engagement section with the at least one engagement projection remains in place during rotation. In the connected position, the engagement section, viewed along the closing direction, is arranged on a first side of the at least one engagement projection, and the belt can be brought into a position relative to the at least one engagement projection, or by rotating the second connecting part relative to the first connecting part, in which the belt extends over the at least one engagement projection on a second side facing away from the first side.
[0012] To connect the two parts, they are positioned so that the engagement section engages with at least one engagement projection on the base body of the first part, thus creating an engagement between the two parts and connecting them together. In the connected position, the second part can be rotated relative to the first part in the direction of closure. This allows for angle-tolerant positioning of the parts. Furthermore, it allows the second part to be rotated relative to the first while in the connected position. During rotation, the engagement section and the at least one engagement projection maintain their engagement.A twisting of the connecting parts relative to each other in the connected position around the closing direction therefore does not lead to a separation of the connecting parts from each other.
[0013] The rotational freedom between the connecting parts in the connected position can allow any rotational movement through any angle. However, it is also conceivable that the movement of the connecting parts is limited to a predetermined angle of rotation, for example by stops or the like. This angle of rotation is preferably greater than 10°, more preferably greater than 20°, and particularly preferably greater than 45° or even greater than 90°.
[0014] Because at least one engagement projection is rigidly and indeformably formed (under a load as intended) on the first base body of the first connecting part, the engagement projection can reliably absorb and dissipate forces when engaging with the engagement section of the second base body. The at least one engagement projection is preferably formed integrally with the first base body of the first connecting part, the first base body being entirely rigid and indeformable.
[0015] In this context, "non-deformable" refers to a fundamentally rigid geometry and material selection of the base body, which ensures that the base body of the first connecting part, with its formed engagement projection, does not deform under a specified load; in other words, the base body is not elastic. For example, the base body of the first connecting part can be made of metal or a hard plastic material.
[0016] Similarly, the base body of the second connecting part with the engagement section formed on it is rigid and non-deformable and is made, for example, of metal or a hard plastic material.
[0017] The connection of the connecting parts is magnetically assisted. For this purpose, the first connecting part has a first magnetic element and the second connecting part has a second magnetic element. In the connected position, the first and second magnetic elements attract each other magnetically and, in particular, assist in the connection of the connecting parts. The magnetic elements exert a magnetic attraction along the closing direction, thus creating a magnetic force that pulls the connecting parts together along this direction. The magnetic elements can, for example, each be a permanent magnet.However, it is also possible to design one of the magnetic devices with a permanent magnet and the other with a magnetic armature, and thus with a passive magnetic element.
[0018] Due to the rotational mobility around the closing direction, a position-tolerant connection of the connecting parts is possible, as it is not necessary to align them in a precisely defined rotational position. The connecting parts can therefore be aligned within a certain angular range or, preferably, in any rotational position, with the connecting parts preferably self-aligning under load.
[0019] To allow rotational mobility in the connected position and position-tolerant alignment, the strap on the second connecting part can be moved into a position relative to the at least one engagement projection in the connected position, or it is in a position where the strap extends over the at least one engagement projection on a side facing away from the engagement section (second side). The strap arranged on the second connecting part (fixed or adjustable) can thus be moved over the at least one engagement projection on the first connecting part – with or without contact with the engagement projection – when the connecting parts are in the connected position and rotated relative to each other.The belt can thus, for example, slide onto at least one engagement projection and be moved over the engagement projection on the side facing away from the ground surface, so that the engagement of the engagement projection of the first connecting part with the engagement section of the second connecting part does not impede the movement of the connecting parts relative to each other.
[0020] It can be provided that the belt always extends over the at least one engagement projection, regardless of the rotational position of the connecting parts relative to each other. Thus, in every rotational position of the connecting parts relative to each other, the belt is arranged such that the at least one engagement projection is located below the belt (with reference to the closing direction). The belt is therefore (always) in a position where it extends over the at least one engagement projection on the second side, the side facing away from the first.
[0021] It can also be designed so that the belt does not extend over the engagement projection in one rotational position, but does extend over it in another. The belt can thus be moved relative to the engagement projection and therefore extends over it or not depending on its rotational position.
[0022] When it is stated that the belt should extend over the at least one engagement projection, it is meant that the belt extends approximately radially away from the second connecting part in the intended manner, and that the section of the belt extending from the second connecting part extends over the at least one engagement projection.
[0023] Moving the belt over the engagement projection can occur with flexible deformation of the belt. However, it is also conceivable that the belt is positioned at such a height on the second connecting piece that it can be moved over at least one engagement projection without deformation.
[0024] In one embodiment, the second connecting part has a fastening section to which the strap is attached. The strap extends freely from an exit point to the fastening section. The fastening section, which can be integrally formed on the second base body (e.g., by injection molding), secures the strap to the second connecting part. At the exit point, the strap exits the fastening section and extends freely beyond the exit point, i.e., outside the fastening section, to the fastening section.
[0025] The exit point is the location where the strap emerges from the fastening section. The strap is fixed to the fastening section. Beyond the exit point, i.e., outside the fastening section, the strap is free and movable relative to the fastening section. The exit point can, for example, extend linearly along the transition between the fastening section and the outside, corresponding to the width of the strap. With a linear exit point, it can be straight or curved.
[0026] The belt is preferably not connected to the base body beyond the exit point, and in particular not to the engagement section, which, for example, projects radially towards the fastening section. The belt can thus move freely radially outside the fastening section relative to the base body. This allows the belt to be moved over the engagement projection of the engagement section without hindering its engagement with the at least one engagement projection.
[0027] In one embodiment, the exit point is spaced radially apart from a rotation axis directed along the closing direction, about which the second connecting part can be rotated relative to the first connecting part in the connected position.
[0028] The exit point can be arranged radially to the axis of rotation, between the axis of rotation and the engagement section. In the case of a linear (straight or curved) extension, the exit point can be located completely or only partially radially within the engagement section.
[0029] Alternatively, the exit point is arranged radially outside the engagement section and thus has a greater radial distance to the axis of rotation than the engagement section. In this case, the exit point, with a linear (straight or curved) extension, can be arranged completely or only partially radially outside the engagement section.
[0030] The spacing from the axis of rotation ensures, in particular, that load forces introduced into the second connecting part via the belt do not lead to an (unwanted) tilting of the second connecting part relative to the first connecting part, and thus the connecting parts are held securely and reliably together in the connected position even under load.
[0031] In one embodiment, the strap is arranged on a first side of the mounting section and extends along this first side of the mounting section. A further strap section can be arranged on a second side of the mounting section, opposite the first side. The first and second sides of the mounting section are, in particular, diametrically opposed to each other with respect to the axis of rotation. The further strap section can be formed by the strap itself, which thus extends through the mounting section. Alternatively, the further basic section can also be formed by a different strap attached to the mounting section.
[0032] While load forces can be transferred to the second connecting part via the strap, and the strap extends from the fastening section towards at least one engagement projection when loaded, the further strap section can, for example, provide an actuation section that a user can grasp to separate the connecting parts. Alternatively, a connection to a higher-level assembly can also be established via this further strap section, so that load forces can also be transferred to the second connecting part via this further strap section.
[0033] In an operational state, for example, another strap is attached to the first connecting part, allowing strap forces to act between the straps on the first and second connecting parts. Alternatively, the first connecting part is attached to a higher-level assembly, such as a garment, a bag, a belt, or the like. A load direction is approximately aligned with the direction of engagement, so that when a load is applied between the connecting parts, the engagement section is drawn into contact with at least one engagement projection.
[0034] In the connecting device, the load direction along which a load force acts on the second connecting part under intended loading conditions can preferably be directed at least with a directional vector component in the direction of engagement. The load direction is thus extended at least approximately in the direction of engagement or obliquely to the direction of engagement, such that the load direction also points in the direction of engagement, namely, when the vector decomposition includes a directional vector component. In the loaded state, the second connecting part is therefore (at least also) loaded in the direction of engagement relative to the first connecting part and thus in the direction of engagement with the at least one engagement projection rigidly formed on the first connecting part.
[0035] In one embodiment, the first connecting part has a locking section rigidly arranged on the first base body. This locking section is configured to interact with the second connecting part in the connected position to block the engagement of the engagement section with the at least one engagement projection in the opposite direction of engagement. Upon rotation, the engagement of the engagement section with the at least one engagement projection and the blocking of the engagement by the locking section remain in effect. In the connected position, the second connecting part is tiltable relative to the first connecting part to release the blocking in the opposite direction of engagement and to allow the at least one engagement section and the at least one engagement projection to be disengaged, thus enabling the separation of the first and second connecting parts.
[0036] The connecting parts are to be aligned along the closing direction, with the alignment of the connecting parts being magnetically assisted by the magnetic devices on the connecting parts. During alignment, the connecting parts are magnetically attracted to each other by the magnetic device and are also held magnetically together in the connected position.
[0037] When the connecting parts are attached, the engagement section of the second connecting part comes into engagement with the at least one engagement projection of the first connecting part in the engagement direction, for example perpendicular or oblique to the closing direction, so that in the connected position a positive locking or force-locking connection exists between the connecting parts and the connecting parts are thus held against each other in a load-bearing manner by the engagement of the engagement section with the at least one engagement projection.The engagement between the engagement section of the second connecting part and the at least one engagement projection of the first connecting part is secured in the connected position by the blocking section of the first connecting part, which is rigidly formed on the first base body of the first connecting part. This is achieved by the blocking section interacting with an associated section of the second connecting part in a blocking manner opposite to the direction of engagement, thus preventing the engagement section from moving towards the at least one engagement projection in the opposite direction, or at least not without releasing the blocking mechanism. Due to the blocking effect of the blocking section, the engagement section is therefore locked in its engagement with the at least one engagement projection, thus securing the connecting parts to each other in the connected position.
[0038] The connecting parts are held in the connected position by the magnetic effect of the magnetic devices in such a way that the locking section of the first connecting part blocks them against each other in the direction of engagement. Therefore, the connecting parts cannot be separated by a (pure) sliding movement in the opposite direction of engagement.
[0039] Rather, to separate the connecting parts, it is necessary to tilt them relative to each other in such a way that the second connecting part is moved in a tilting plane defined by the closing and engagement directions relative to the first connecting part, such that the second connecting part can be moved opposite to the engagement direction towards the blocking section. By tilting the second connecting part relative to the first connecting part, the blocking effect of the blocking section can be released, allowing the second connecting part to move over the blocking section and thus disengaging the engagement section of the second connecting part from at least one engagement projection of the first connecting part.
[0040] The blocking action of the rigidly formed blocking section on the first base body of the first connecting part prevents the second connecting part from moving linearly in the opposite direction of engagement. Instead, it causes the connecting parts to tilt in a plane defined by the closing and engagement directions to separate them. This tilting movement can occur about a defined tilting axis. Alternatively, the tilting movement can occur along a curved path within the tilting plane, causing the second connecting part to tilt relative to the first. This tilting movement can be superimposed with a linear movement in the opposite direction of engagement and / or the opposite direction of closing.
[0041] It should be noted that the connecting parts can be tilted relative to each other for separation. However, the connection between the connecting parts is not established by a linear closing motion, but rather by placing the connecting parts together in a wobbling, tilted position and engaging them. During the connection process, the second connecting part can also be tilted relative to the first to allow the engagement section of the second connecting part to engage with at least one engagement projection of the first connecting part.
[0042] In one embodiment, the second connecting part can be tilted relative to the first connecting part on a side facing away from the at least one engagement projection, contrary to the closing direction. In the connected position, the second connecting part engages with the at least one engagement projection on the first base body of the first connecting part via the engagement section rigidly formed on the second base body, with this engagement occurring in a forward region of the second connecting part with respect to the direction of engagement.With a rearward area relative to the direction of engagement, the second connecting part can be lifted from the first connecting part in the connected position opposite to the closing direction, in order to tilt the second connecting part relative to the first connecting part and thereby eliminate the blocking effect of the blocking section of the first connecting part, so that the second connecting part can be moved to the blocking section of the first connecting part and the engagement section can be brought out of engagement from at least one engagement projection opposite to the direction of engagement.
[0043] To facilitate handling for the user, the second connecting piece can, for example, have an actuating section that allows the user to tilt the second connecting piece relative to the first. This actuating section could be, for instance, a tab at the rear of the second connecting piece, which the user can pull to lift the rear of the second connecting piece away from the first, in the opposite direction to the closing direction. Alternatively, the actuating section could be shaped like a recessed grip or other handle, allowing the user to grasp and tilt the second connecting piece relative to the first.
[0044] In one embodiment, the second connecting part has a locking element rigidly attached to the second base body for interaction with the locking section of the first connecting part. The locking element can, for example, be formed on a base section of the second connecting part that forms the engagement section and project from the base section along the closing direction. In the connected position, the locking element interacts with the locking section of the first connecting part, thus preventing movement of the connecting parts relative to each other in the opposite direction of engagement.However, by tilting the connecting parts relative to each other, the blocking element can be lifted over the blocking section in order to release the blockage and move the connecting parts relative to each other in the opposite direction of engagement, so that the engagement between the engagement section of the second connecting part and at least one engagement projection of the first connecting part can be released and the connecting parts can be separated from each other.
[0045] For example, the locking element can be cylindrical and, viewed in a cross-sectional plane perpendicular to the closing direction, have a circular shape. In the connected position, the locking element can be rotated about the closing direction relative to the locking section, thus allowing the connecting parts to rotate relative to each other.
[0046] In one embodiment, the first base body has a recess that is at least partially bounded by the locking section. In the connected position, the locking element rests in the recess, so that the engagement of the engagement section with the at least one engagement projection is blocked in the opposite direction of engagement. The recess can, for example, be formed as a depression on a base surface of the first base body of the first connecting part. The recess is thus formed into the base surface. The locking element engages with the recess when the connecting parts are brought together, so that the engagement holds the second connecting part against the at least one engagement projection of the first connecting part.
[0047] In one embodiment, the recess (in a cross-sectional plane perpendicular to the closing direction) is bounded by at least one boundary wall, which forms the blocking section and extends along a circular arc. The recess can, for example, have a circular basic shape, in which the at least one boundary wall extends in an arc along an (imaginary) circle centered on an axis.
[0048] For example, the recess is bounded by two arc-shaped boundary walls, which together form the blocking section and, in the connected position, accommodate the blocking element of the second connecting part between them, thus preventing movement against the direction of engagement of the second connecting part relative to the first connecting part. The one or more boundary walls are, for example, arranged at a right angle to the base surface, thereby providing support surfaces for the blocking element, so that under load, the blocking element is supported against the boundary walls and thus blocked relative to the first connecting part.
[0049] In one embodiment, the locking section has a ramp. The ramp is designed to provide a sliding guide for the locking element against the direction of engagement when the second connecting part tilts relative to the first. When the connecting parts tilt relative to each other, for example, a locking element of the second connecting part can come into contact with the ramp, allowing the locking element to run onto the ramp and thus move across the locking section. Such a ramp facilitates the separation of the connecting parts.
[0050] In one embodiment, at least one engagement projection is curved in an arc around the closing direction. If a single engagement projection is provided, it extends in an arc around the closing direction. If several engagement projections are provided, each engagement projection can, for example, extend in an arc around the closing direction. Additionally or alternatively, the engagement projections can be arranged along a circumferential direction pointing around the closing direction, so that the engagement projections are arranged along an arc-shaped line and together engage with the engagement section of the second connecting part when the connecting parts are in the connected position.
[0051] The at least one engagement projection extends around the closing direction at an angle of less than 180°, preferably less than 150°, to allow the engagement section to engage with the at least one engagement projection in the direction of engagement.
[0052] The at least one engagement projection preferably forms an undercut with respect to the closing direction. The at least one engagement projection is thus undercut with respect to the closing direction in that the at least one engagement projection projects transversely to the closing direction from an associated section of the first connecting part.
[0053] The undercut can be formed by a surface extending perpendicular or obliquely (at an acute or obtuse angle) to the closing direction.
[0054] Similarly, the engagement section of the second connecting part preferably forms an undercut with respect to the closing direction. The engagement section is thus undercut with respect to the closing direction by projecting transversely to the closing direction from an associated section of the second connecting part.
[0055] The undercut can in turn be formed by a surface extending perpendicular or obliquely (at an acute or obtuse angle) to the closing direction.
[0056] In one embodiment, the engagement section extends circumferentially around the closing direction. The engagement section can, for example, be arranged on a pin element and project from the pin element transversely to the closing direction.
[0057] For example, the engagement section is rotationally symmetrical with respect to the closing direction. This allows the engagement section to engage with the at least one engagement projection on the first connecting part in any rotational position of the second connecting part relative to the first connecting part, so that an engagement exists between the engagement section and the at least one engagement projection in any rotational position of the second connecting part relative to the first connecting part, and the connecting parts can thus be rotated relative to each other without the engagement of the engagement section with the at least one engagement projection being released.
[0058] In one embodiment, the second basic body of the second connecting part has a base section.
[0059] In one embodiment, the base section can form the engagement section, such that the engagement section is shaped to engage with at least one engagement projection of the first connecting part on the base section, for example on a circumferential edge section of the base section.
[0060] In another embodiment, the engagement section is spaced apart from the base section along the closing direction. The engagement section is thus spatially separated from the base section, for example, by the base section extending along a first plane and the engagement section extending along a second plane spaced apart from the first plane along the closing direction.
[0061] If the engagement section is spatially separated from the base section, the engagement section is, for example, formed on a pin element that projects from the base section along the closing direction. The engagement section projects from the pin section along the engagement direction and thus forms an undercut, allowing the engagement section to engage with at least one engagement projection of the first connecting part to create a positive-locking or force-locking connection.
[0062] The engagement section can, for example, be formed entirely on the pin element. In this way, a mushroom-shaped engagement element can be provided which, in any rotational position, can be brought into engagement with at least one engagement projection of the first connecting part in order to connect the connecting parts and hold them together in the connected position.
[0063] If the engagement section is spatially spaced apart from the base section, the base section can extend radially further in the closing direction than the engagement section and thus project radially beyond it. The engagement section is therefore in a radially inner position, while an outer edge of the base section is located radially outside the engagement section. In this way, the base section can provide favorable support for the second connecting part against the first connecting part when the connecting parts are in their connected position.
[0064] In one embodiment, the base section is, for example, disc-shaped. The base section can, for instance, have a circular cylindrical shape with a circular cross-section.
[0065] For example, a fastening section can be formed on the base section, via which a strap is connected to the second connecting part.
[0066] In one embodiment, the base section of the second body of the second connecting part has an edge section. The first connecting part, in contrast, has a support section rigidly formed on the first body, whereby, in the connected position, the edge section is supported by the support section to bear a load along the direction of engagement. The edge section can, for example, be formed in a front region of the base section, and—in the case of a circular cylindrical design of the base section—the edge section can also encircle the base section completely. The support section is formed in a front region of the first connecting part with respect to the direction of engagement, so that the support section can provide support for the base section in the direction of engagement.When the second connecting part is loaded relative to the first connecting part in the direction of engagement, the edge section is pressed against the support section and thus braced against it. Via the edge section, the base section, in the connected position, can thus come into contact with the support section on the first base body of the first connecting part, allowing load forces to be transferred from the second connecting part to the first connecting part.
[0067] It is conceivable that the edge section, in the connected position, is always in contact with the support section in the direction of engagement. Alternatively, it can also be provided that, in an unloaded position, the edge section is not in contact with the support section in the direction of engagement, but only comes into contact with the support section when the connecting parts are loaded relative to each other.
[0068] Forces can be advantageously transferred from the second connecting part to the first connecting part via the support section and the bracing of the edge section of the base section against the support section. For example, when the connecting device is designed as a webbing fastener, the load direction along which a force acts between the connecting parts during intended use of the connecting device can be (approximately) directed along the direction of engagement, so that when loaded, the engagement section is loaded in the direction of engagement with the at least one engagement projection. In this case, the edge section of the base section comes into a supporting position against the support section, so that forces acting in the direction of engagement are transferred via the contact of the edge section against the support section.The at least one engagement projection serves in particular to provide support along the closing direction and thus to ensure that the connecting parts stay in contact with each other, whereby load forces in the engagement direction are primarily absorbed and dissipated via the support section.
[0069] In one embodiment, the support section and the edge section are each curved in an arc-shaped pattern in a cross-sectional plane perpendicular to the closing direction. If the base section is cylindrical, the edge section of the base section curves circularly around the closing direction. The curvature of the support section corresponds to the curvature of the edge section of the base section, so that in the connected position, the base section can come into a supporting position with the support section of the first connecting part.
[0070] In one embodiment, the support section, viewed along the closing direction, is spaced apart from at least one engagement projection. The support section can extend above or below the at least one engagement projection, viewed along the closing direction.
[0071] Additionally or alternatively, the support section, viewed along the direction of engagement, can be spaced apart from the at least one engagement projection. The support section is thus located at a different position than the at least one engagement projection with respect to the direction of engagement. In particular, the support section can be positioned upstream of the at least one engagement projection in the direction of engagement, such that the support section is arranged radially outside the at least one engagement projection. In this way, favorable support can be achieved via the support section, as the base section can come into contact with the support section with a favorable lever arm when load forces act between the connecting parts.
[0072] The support section, in one embodiment, is formed by a surface section that is parallel or inclined to the closing direction. The support section is rigidly attached to the first base body of the first connecting part. Under load, the support section of the first connecting part comes into contact with the base section of the second connecting part, so that load forces acting in the direction of engagement can be absorbed and transferred effectively.
[0073] In one embodiment, the first connecting element has two engagement projections spaced apart from each other along a transverse direction perpendicular to both the engagement direction and the closing direction. At least one section of the support element is arranged between the engagement projections and, furthermore, spaced apart from the engagement projections along the engagement direction. Because the engagement projections are spaced apart from each other along the transverse direction extending perpendicular to the engagement direction, and preferably arranged in the same axial position when viewed along the engagement direction, a load exerted by the engagement element on the engagement projections has a directional vector component (also) in the direction of spreading the engagement projections apart along the transverse direction, which could potentially be detrimental to the stability of the connection.For this reason, an additional support section is provided, which is arranged at least with one section (viewed along the transverse direction) between the engagement projections and also spaced apart from the engagement projections along the direction of engagement. Thus, at least one section of the support section is located between the engagement projections and in front of them in the direction of engagement, so that the support section can support an edge section of the engagement section of the second connecting part and thus absorb a load when loaded in the direction of engagement.
[0074] Because the support section thus acts as a brace in the direction of engagement, excessive stress, particularly in the direction of spreading at the engagement projections under load on the connection device, is avoided. The stability of the connection can therefore be improved.
[0075] In one embodiment, the base section has a base surface and the first base body has a bottom surface. The base surface and the bottom surface each extend perpendicular to the closing direction. In the connected position, the base surface on the base section of the second connecting part and the bottom surface on the first base body of the first connecting part face each other.
[0076] For example, in the connected position, a connection can exist between the base surface and the bottom surface. When the connecting parts are rotated relative to each other in the closing direction, the base surface and the bottom surface slide against each other.
[0077] However, this is not mandatory. It is also conceivable that in the connected position there is a gap (and therefore no connection) between the base surface and the ground surface.
[0078] In one embodiment, the base section can be tilted about a tilting axis perpendicular to both the closing and engagement directions relative to the first connecting part, in order to tilt the connecting parts relative to each other. The tilting of the connecting parts to separate them is thus achieved by tilting the base section about a tilting axis relative to the first base body of the first connecting part. The tilting axis can be defined by a line connecting the base section and the first base body. Alternatively, the tilting axis could correspond to an imaginary line extending through or outside the base section, and to a line about which the base section pivots relative to each other when the connecting parts are tilted.
[0079] In one embodiment, the first base body has an insertion opening into which a section of the base section can immerse when the second connecting part is tilted relative to the first connecting part in the closing direction. The insertion opening can be formed, in particular, in a front region of the first base body (with respect to the direction of engagement) and, for example, be shaped as a recess on the first base body. The base section can immerse into the insertion opening, particularly with a front edge section, when the connecting parts are tilted relative to each other (during connection or separation).
[0080] The insertion opening can, for example, be shaped as a recess relative to the base surface of the first base body. In this case, the insertion opening abuts the base surface but is recessed relative to it and thus set back along the closing direction. The insertion opening can extend, in particular, below the at least one engagement projection and thus provide a space in the area of the at least one engagement projection into which the base section of the second connecting part can insert its edge section, both when the connecting parts are joined to close the connecting device and when they are separated to open it.
[0081] If the engagement section is spatially separated from the base section, the immersion opening can, for example, also be formed as a depression radially outside the at least one engagement projection and create a space for the immersion of an edge of the base section.
[0082] In general, a play between the engagement section of the second connecting part and at least one engagement projection of the first connecting part can facilitate tilting the connecting parts relative to each other for joining and also for disconnecting. Alternatively, a space to provide play can be created, for example, by a chamfer on the engagement section, which allows the engagement section to tilt relative to the at least one engagement projection.
[0083] Particularly when the engagement section is formed on a circumferential edge section of the base section, the insertion opening is, for example, formed as a depression relative to a bottom surface of the first connecting part and adjoins the bottom surface in an area facing the support section. The insertion opening can, for example, extend between the support section and the bottom surface.
[0084] If the engagement section is formed on a pin below the base section and the base section projects radially beyond the engagement section, the immersion opening is preferably formed radially outside the at least one engagement projection on the first base body.
[0085] The immersion opening can be designed as a recess or as a through-opening on the first base body.
[0086] In one embodiment, the first base body has a positive-locking section against which the base section rests in the connected position of the first and second connecting parts to counteract tilting of the second connecting part relative to the first connecting part. The positive-locking section is formed, in particular, in a forward region of the first base body with respect to the direction of engagement and is rigidly attached to the first base body. The base section is supported by the positive-locking section, particularly in the closing direction, so that tilting of the second connecting part relative to the first connecting part is at least hindered by the support on the positive-locking section.
[0087] When tilting to separate the connecting parts, the second base body is disengaged from the positive locking section on the first base body by a slight movement opposite to the direction of engagement within a certain clearance. This clearance can be provided between the second connecting part and the locking section of the first connecting part, allowing a (slight) displacement of the second connecting part against the direction of engagement, or between the second connecting part and at least one engagement projection, allowing a (slight) tilting movement followed by a displacement of the second connecting part against the direction of engagement. Through this movement within the clearance, the second base body disengages from the positive locking section, for example, by sliding off the positive locking section, which may be shaped like a step.The connecting parts can then be tilted (more strongly) towards each other so that they can be separated.
[0088] The positive locking section can, for example, be formed by a step on which the base section rests in the connected position. In particular, the positive locking section can have a surface section oriented perpendicular or obliquely to the closing direction, which provides support for the base section.
[0089] In another embodiment, the positive locking section can also be formed as an engagement opening, for example in the form of a notch, on the support section. The positive locking section provides support on the base section perpendicular to the direction of engagement, namely along the closing direction, so that the connected parts cannot easily and unintentionally tilt towards each other when loaded, but are instead supported against (unintentional) tilting by the positive locking section.
[0090] In one embodiment, the positive locking section, viewed along the closing direction, is spaced apart from at least one engagement projection. The positive locking section can extend above or below the at least one engagement projection, viewed along the closing direction.
[0091] Additionally or alternatively, the positive locking section, viewed along the direction of engagement, can be spaced apart from the at least one engagement projection. The positive locking section is thus located at a different position than the at least one engagement projection with respect to the direction of engagement. In particular, the positive locking section can be positioned upstream of the at least one engagement projection in the direction of engagement, such that the positive locking section is arranged radially outside the at least one engagement projection. In this way, favorable support against tilting of the connecting parts relative to each other can be created via the positive locking section, as the base section can come into contact with the positive locking section with a favorable lever arm when load forces act between the connecting parts.
[0092] In one embodiment, the at least one engagement projection has, for example, a sliding ramp which serves as a guide ramp to guide the connecting parts when they are placed against each other in such a way that the connecting parts can be brought into engagement with each other in an easy, preferably largely automatic manner.
[0093] Preferably, the sliding ramp is designed to guide the second connecting part, when it is attached to the first connecting part along the closing direction, along the at least one engagement projection such that the second connecting part is displaced opposite to the engagement direction of the first connecting part and is thereby moved past the at least one engagement projection. After passing the projection, the second connecting part can then be brought into engagement with the at least one engagement projection of the first connecting part in the engagement direction. By sliding along the at least one engagement projection, the second connecting part is thus guided relative to the first connecting part in such a way that the second connecting part is moved past the at least one engagement projection.Once the second connecting part has passed the at least one engagement projection with its engagement section, the engagement section can be brought into engagement with the at least one engagement projection on the first connecting part in the direction of engagement.
[0094] The strap is fixed and non-adjustable in one design, but may also be adjustable on the second connecting part.
[0095] The first connecting part can also be connected to a strap, but can also be arranged on an associated assembly, for example a textile object or another object.
[0096] In one embodiment, the first connecting part has two engagement projections spaced apart from each other transversely to the closing direction and transversely to the engagement direction such that the belt can be guided between the engagement projections when the first and second connecting parts are connected. The belt is thus received between the engagement projections, so that the engagement projections on both sides of the belt provide support for the second connecting part relative to the first connecting part.
[0097] The following list of possible uses is intended to illustrate the diverse applications of the connecting device, but is not intended to be limiting or, in particular, exhaustive.

[0099] In a Fig. 1 bis 12A-12F In the illustrated embodiment, a connecting device 1 has a first connecting part 2 (so-called female part) and a second connecting part 3 (so-called male part) to be attached to the first connecting part 2.
[0100] The connecting parts 2, 3 can generally be attached to each other along a closing direction X, wherein the connecting parts 2, 3 each have a magnetic device 21, 31 in the form of a permanent magnet (or alternatively on the one hand in the form of a permanent magnet and on the other hand in the form of a magnetic armature) which interact magnetically attractively and attract the connecting parts 2, 3 towards each other along the closing direction X.
[0101] It should be noted that the connecting parts 2, 3 can also be attached in a direction deviating from the closing direction X, for example, at an angle to the closing direction X. The magnetic devices 21, 31 attract each other magnetically along the closing direction X and draw the connecting parts 2, 3 towards each other along the closing direction X.
[0102] As can be seen from the exploded views according to Fig. 2A and 2B as well as the separate views according to Fig. 3A, 3B und 4A-4C As can be seen, the first connecting part 2 has a base body 20 that forms a receiving opening 23 for receiving the second connecting part 3. A webbing receptacle 22 in the form of a bridge and an adjoining opening is arranged on the base body 20, to which a webbing 5 can be attached or is attached. On one side facing away from the receiving opening 23, the base body 20 forms a mounting opening 25 for receiving the magnetic device 21.
[0103] The receiving opening 23 is formed as a recess in the base body 20. Within the receiving opening 23, a base surface 230 is formed in the form of a flat surface extending perpendicular to the closing direction X, with which the second connecting part 3 can be brought into a flat contact when inserted into the receiving opening 23 to establish a connection between the connecting parts 2 and 3.
[0104] A recess 231 in the form of a depression is formed in the base surface 230, into which - as will be described below - in the connected position of the connecting parts 2, 3 a blocking element 303 engages on a base section 300 of the second connecting part 3.
[0105] The receiving opening 23 is bounded at a front end by a support section 233, which serves as a support and load-bearing element for the second connecting part 3 in the connected position. Between the support section 233 and the base surface 230, an immersion opening 232 is formed, which serves to facilitate both the joining and the separation of the connecting parts 2 and 3 by allowing an edge section 305 of the base section 300 of the second connecting part 3 to immerse itself in the immersion opening 232 during both the joining and separation of the connection, as is the case, for example, in Fig. 10B This is evident and will be described below.
[0106] The insertion opening 232 is shaped as a depression relative to the base surface 230 and connects to the base surface 230 in such a way that the insertion opening 232 is located between the support section 233 and the base surface 230. At the transition between the insertion opening 232 and the base surface 230, a chamfered transition surface 237 is formed, which serves as a guide for the second connecting part 3 for making the connection as well as for breaking the connection.
[0107] On the rigidly formed base body 20, engagement projections 240, 241 are rigidly formed with the base body 20 on two lateral, raised sections 242, 243. These projections are located above the base surface 230 when viewed along a vertical direction H pointing along the closing direction X and serve to establish a positive-locking or force-locking connection between the connecting parts 2, 3 in the connected position. The engagement projections 240, 241 are spaced apart from each other along a transverse direction Q. Together, the engagement projections 240, 241 form an engagement device 24, which enables a positive-locking or force-locking engagement with the second connecting part 3.As will be explained below, the base section 300 of the second connecting part 3 is received in a connected position with an engagement section 341 formed on it between the engagement projections 240, 241 and the bottom surface 230 and is also supported at a front edge 305 on the support section 233, so that the connecting parts 2, 3 are held securely and reliably together.
[0108] Sliding ramps 244, 245 are formed on the engagement projections 240, 241, which are inclined obliquely to the vertical direction H and cause the second connecting part 3 to slide against an engagement direction Y when the connecting parts 2, 3 are placed against each other along the closing direction X.
[0109] The recess 231 is laterally bounded by arc-shaped boundary walls 236, which together form a blocking section of the first connecting part 2 and are oriented perpendicular to a base of the recess 231 and also to the base surface 230. The boundary walls 236 extend in a circular arc around a central axis B of the recess 231, which is directed along a normal direction N of the base surface 230.
[0110] Between the boundary walls 236 a ramp 235 is formed, which is located behind the support section 233 at the recess 231 and provides a sliding surface to facilitate the insertion of the locking element 303 into the recess 231 and also the removal of the locking element 303 from the recess 231.
[0111] The floor area 230 extends along a plane perpendicular to the normal direction N.
[0112] The second connecting part 3 is, as can be seen from the exploded views according to Fig. 2A , 2B as well as the separate views according to Fig. 5A, 5B and 6A-6C The second connecting part 3 has a base body 30 on which the strap 4 is fixedly and non-adjustably arranged, by the strap 4 being inserted into a strap receptacle 32 formed between a base section 300 and a fastening section 301 and thereby being fixedly arranged on the base body 30.
[0113] The base body 30 can, for example, be formed in one piece and integrally by plastic injection molding together with the base section 300 and the fastening section 301, wherein the belt 4 is overmolded section by section and is thus firmly and immovably connected to the base body 30.
[0114] The base section 300 has a circular cylindrical shape and forms a base surface 302 on one side facing the first connecting part 2 (when the connection is made), which is flat and, when the second connecting part 3 is attached to the first connecting part 2, comes into contact with the bottom surface 230 in the receiving opening 23.
[0115] From the base surface 302, a blocking element 303, concentric to the circular cylindrical base section 300 and circular in cross-section, projects and serves to engage in the recess 231 on the bottom surface 230 of the base body 20 of the first connecting part 2.
[0116] Within the blocking element 303 a fastening opening 35 is formed, which serves to receive the magnetic device 31, for example in the form of a permanent magnet of the second connecting part 3, and within which the magnetic device 31 is fastened.
[0117] The base section 300 forms an engagement device 34 of the second connecting part 3 with an engagement section 341, which serves to interact with the engagement projections 240, 241 of the engagement device 24 of the first connecting part 2 and dips under the engagement projections 240, 241 when the connection is made, so that a positive locking or force-fit connection is made between the connecting parts 2, 3.
[0118] In the illustrated embodiment, the engagement section 341 is formed by a circumferential edge of the base section 300, which projects radially towards the fastening section 301 and thus forms an undercut, through which the engagement section 341 can engage with the engagement projections 240, 241 of the first connecting part 2, which also form undercuts, in order to connect the connecting parts 2, 3 together.
[0119] Based on Fig. 7A, 7B bis 11A-11D A connection process of the connection device 1 is shown.
[0120] The connecting parts 2, 3 are generally brought together along the closing direction X, along which the magnetic devices 21, 31 interact magnetically, thus attracting the connecting parts 2, 3 towards each other. The connecting parts 2, 3 can be brought close together manually, whereby, beyond a certain point of proximity, the magnetic attraction automatically engages the connecting parts 2, 3, thus establishing the connection of the connecting device 1. Therefore, an imprecise initial positioning of the connecting parts 2, 3 is sufficient, as the connection is then established largely automatically.
[0121] If the connecting parts 2, 3 are brought closer together, as shown from Fig. 7A und 7B As can be seen, the base section 300 of the base body 30 of the second connecting part 3 comes into contact with the engagement projections 240, 241 along the closing direction X from above, as can be seen from Fig. 8A, 8B This is evident. Due to the inclined sliding ramps 244, 245 formed on the engagement projections 240, 241, the base section 300 slides along a sliding direction A on the engagement projections 240, 241, with the base section 300 having a Fig. 8B The rear edge 304 can come into contact with the base surface 230 in the receiving opening 23 of the first connecting part 2 and thus slides in a guided manner along the base surface 230 without the blocking element 303 becoming prematurely engaged.
[0122] If the base section 300 has slid off the engagement projections 240, 241 and has thus passed the engagement projections 240, 241 in the closing direction X, then the engagement section 341 formed on the circumferential edge of the base section 300 now slides, supported by the magnetic attraction of the magnetic devices 21, 31, in an engagement direction Y into engagement with the engagement projections 240, 241, as can be seen from Fig. 9A, 9B and 10A, 10B This movement along (approximately) the direction of engagement Y is magnetically assisted, and an additional load force (introduced via belt 4) can support the engagement.
[0123] When the engagement section 341 moves in the engagement direction Y into engagement with the engagement projections 240, 241, the blocking element 303 slides into the recess 231 in the receiving opening 23 of the first connecting part 2, as is the case in the transition from Fig. 10A, 10B towards Fig. 11A-11D as is evident.
[0124] In the Fig. 11A-11D In the apparent, connected position, the blocking element 303 lies in the recess 231, and the base section 300 with the base surface 302 formed on it lies flush against the bottom surface 230 within the receiving opening 23 of the first connecting part 2, as can be seen in particular from the sectional view according to Fig. 11B as is evident.
[0125] In the connected position, the base section 300 with a (front) edge section 305 faces the support section 233 and rests against the support section 233 in a supporting manner. If a force is introduced into the second connecting part 3 via the belt 4, this force is absorbed and transferred by the supporting contact of the base section 300 against the support section 233.
[0126] As this is shown Fig. 11C und 11D As can be seen, the support section 233 is curved in an arc around the closing direction X, corresponding to the curvature of the circular cylindrical base section 300, so that a structure exists along an arc-shaped support line or surface between the edge section 305 at the base section 300 and the support section 233.
[0127] The support section 233 is arranged with a central section, viewed along the transverse direction Q, between the engagement projections 240, 241 and is spaced at a distance from the engagement projections 240, 241 along the engagement direction Y at the central section. The support section 233 extends in the cross-sectional plane according to Fig. 11D arc-shaped to below the engagement projections 240, 241 and beyond, so that a planar support for the base section 300 is created centrally between the engagement projections 240, 241 and also directly in the area of the engagement projections 240, 241.
[0128] In the connected position, the strap 4 is arranged on the connecting part 3 approximately at the level of the engagement projections 240, 241 on the connecting part 2 or below the engagement projections 240, 241. This ensures that strap forces introduced via the strap 4 cannot tilt the connecting part 3 in the receiving opening 23 or can only generate a small tilting moment, with the engagement projections 240, 241 securing the position of the connecting part 3 on the connecting part 2, particularly along the vertical direction H.
[0129] In the connected position and under load effects between the connecting parts 2, 3, the belt 4 lies between the raised sections 242, 243 and is thus arranged between the engagement projections 240, 241, so that the engagement projections 240, 241 create a support symmetrical to the belt 4 when a force is introduced via the belt 4.
[0130] In the connected position, the magnetic devices 21, 31 attract each other magnetically and thus hold the connecting parts 2, 3 in the connected position.
[0131] Due to the engagement of the locking element 303 in the recess 231, a tangential displacement of the connecting parts 2, 3 relative to each other in the direction of engagement Y is also blocked. In the connected position, the locking element 303 lies in the recess 231 such that it is received between the boundary walls 236 that constitute the locking section and is in a blocking position with the arc-shaped boundary walls 236, so that the locking element 303 cannot be moved towards the boundary walls 236 in the direction of engagement Y.
[0132] Due to the rotationally symmetric shape of the blocking element 303 and the circular cylindrical shape of the base section 300, the connecting part 3 can be moved in the connected position along a circumferential direction U (see Fig. 1 ) about an axis of rotation R within the receiving opening 23 of the connecting part 2 by any angle about an axis of rotation R, while maintaining the connecting engagement between the connecting parts 2, 3 and also the blocking of the blocking element 303 in the recess 231.
[0133] This rotatability also allows the connecting parts 2 and 3 to be attached to each other in any rotational position. When a load is applied via the strap 4, the connecting parts 2 and 3 align themselves relative to each other so that the strap 4 lies between the engagement projections 240 and 241, thus ensuring that connecting part 3 is symmetrically supported against connecting part 2. Due to this rotatability, the connecting parts 2 and 3 can be attached to each other with tolerance in their position, making the connection process simple and convenient.
[0134] As this is shown Fig. 10A-10C As can be seen, the base section 300, with a front edge section 305, dips into the insertion opening 232, which is recessed both towards the base surface 230 and the recess 231, when it slides under the engagement projections 240, 241. The insertion of the edge section 305 into the insertion opening 232 allows the locking element 303 to slide into the recess 231, thus enabling the engagement of the engagement section 341 formed on the base section 300 with the engagement projections 240, 241. This also increases the angular range of an opening force acting on the actuating section 40 (tab) and prevents the edge section 305 from jamming during opening.
[0135] In the connected position, the front edge section 305 of the base section 300 then rests on a form-fitting section in the form of a step 234 formed between the immersion opening 232 and the support section 233 and located at the level of the bottom surface 230, as can be seen in particular from Fig. 11B This is evident. By attaching the base section 230 to the step 234, the connecting part 3 is additionally supported against tipping towards the connecting part 2.
[0136] The positive locking section can alternatively also be formed, for example, by a notch or the like on the support section 233, into which the base section 300 engages with the edge section 305 and is thereby supported on the support section 233 against tilting, which is accompanied by a movement of the edge section 305 on the support section 233 downwards in the closing direction X.
[0137] The positive locking section in the form of step 234 ensures that in the connected position according to Fig. 11A bis 11D In particular, this counteracts tilting under load on the belt 4. Thus, in the connected position, the second connecting part 3, with its base body 30, rests on the bottom surface 230 of the base body 20 of the first connecting part 2 in a first area formed by the rear area (with reference to the direction of engagement Y). In a second area adjoining the direction of engagement Y, formed by the area above the insertion opening 232, the second base body 30 of the second connecting part 3, in contrast, does not rest against the first base body 20 of the first connecting part 2.With a third area adjoining the second area in the direction of engagement Y, formed by the front edge section 305 of the base section 300, the second base body 30 rests on the step 234, so that in the connected position a support in the form of a two-point support is created, with a free space created in between in the area of the immersion opening 232.
[0138] In the loaded position, the base section 300 with the front edge section 305 is loaded against the support section 233 and thus held in a self-reinforcing manner in contact with the step 234.
[0139] If the connecting parts 2 and 3 are to be separated from each other, the movement sequence proceeds as follows: Fig. 7A, 7B bis 11A-11D The process is essentially reversed. In particular, to separate the connecting parts 2, 3, a user can grasp an actuating section in the form of a tab 40 (formed by a protruding section of the belt 4) on a rear side of the connecting part 3 facing away from the engagement projections 240, 241, thereby lifting the connecting part 3 at its rear end from the base surface 230 and thus removing the connecting part 3 from the connected position according to Fig. 11A-11D tilt to the connecting part 2 in such a way that the base section 300 with the front edge section 305 slides off the step 234 and the blocking element 303 is lifted out of the recess 231, as shown from Fig. 10A und 10B This is evident. In this way, the blockage opposite to the direction of engagement Y between the connecting parts 2, 3 is lifted, so that the connecting part 3 can be pulled out of engagement from the connecting part 2 opposite to the direction of engagement Y and the connecting parts 2, 3 can thus be separated from each other.
[0140] The tilting occurs in a tilting plane that is perpendicular to the base surface 230, namely defined by the closing direction X and the engagement direction Y. The tilting occurs approximately about a tilting axis K (see Fig. 10A und 10B ) such that the connecting part 3 performs a pivoting movement in the tilting plane perpendicular to the tilting axis K and thus the blocking element 303 is lifted out of the recess 231, so that the connecting parts 2, 3 can be moved towards each other in the opposite direction of engagement Y and thus separated from each other.
[0141] If, particularly when the connecting device 1 is unloaded, the connection of the connecting parts 2, 3 is to be released, the connecting parts 2, 3 are tilted relative to each other and, in particular, also moved relative to each other against the direction of engagement Y, so that the front edge section 305 of the base section 300 (forming the third area) slides off the step 234 and enters the area of the immersion opening 232, as shown from Fig. 10B This is evident. The positive locking section created by stage 234 no longer counteracts tilting, so that the connecting parts 2, 3 can be conveniently and easily separated from each other via the actuating section 40 in case of tilting.
[0142] Fig. 12A bis 12F The connecting device 1 is shown in a rotated position of the second connecting part 3 relative to the first connecting part 2. The second connecting part 3 can be attached to the first connecting part 2 in any rotated position, and in any rotational position, the engagement section 341 of the second connecting part 3 can be brought into engagement with the engagement projections 240, 241 of the first connecting part 2. In the connected position, the second connecting part 3 is rotatable relative to the first connecting part 2 along the circumferential direction U about the axis of rotation R, while maintaining the engagement of the engagement section 341 with the engagement projections 240, 241 and while the locking element 303 engages in the recess 231.
[0143] Under load, when belt forces act between the belts 4, 5 in the connected position of the connecting device 1, the belt 4 lies between the engagement projections 240, 241, as can be seen from Fig. 1 The engagement projections 240, 241 are arranged laterally to the side of the belt 4, so that the belt 4 extends between the engagement projections 240, 241 (viewed along the transverse direction Q pointing from engagement projection 240 to engagement projection 241).
[0144] In contrast, is the second connecting part 3, as shown in the diagram? Fig. 12A bis 12F As can be seen, the belt 4 is twisted along the circumferential direction U about the axis of rotation R to the first connecting part 2, so that the belt 4 can extend over one of the engagement projections 240, 241, with flexible, bendable deformation of the belt 4, as can be seen in particular from Fig. 12B and 12DThis is evident. When twisted, the belt 4 (depending on the direction of rotation) slides onto one of the engagement projections 240, 241 and is thereby deformed, so that the belt 4 can be moved over the respective engagement projection 240, 241.
[0145] As this is shown Fig. 1 for example, in conjunction with Fig. 6C As can be seen, the strap 4 exits the fastening section 301 above the base section 300 at an exit line 306, which is curved according to the cylindrical shape of the fastening section 301. Beyond the exit line 306, i.e., outside the fastening section 301, the strap 4 is not connected to the base section 300 in the area of the projecting edge section forming the engagement section 341, but can move freely relative to the base section 300 and, in particular, can be lifted off the base section 300. This allows the strap 4 to deform smoothly and slide onto the engagement projection 240, 241 when the connecting part 3 is rotated relative to the connecting part 2.
[0146] The exit line 306 is offset radially inwards relative to the end-face edge section 305 of the base section 300 and is thus radially spaced from the edge section 305. The belt 4 therefore exits the fastening section 301 along a line that is set back relative to the edge section 305.
[0147] The exit point 306 is radially spaced from the axis of rotation R, about which the connecting parts 2, 3 can be rotated relative to each other in the connected position, wherein the exit point 306 is arranged on a side of the fastening section 301 facing the engagement projections 240, 241 when the connecting device 1 is loaded.
[0148] The exit line 306 can, viewed along the direction of action Y, be arranged between the axis of rotation R and an imaginary line extending between the engagement projections 240, 241, or can have a greater distance (along the direction of action Y) to the axis of rotation R than the engagement projections 240, 241.
[0149] As this is shown Fig. 11C As can be seen, in the illustrated embodiment the exit point 306 is arranged at approximately the same axial position along the direction of engagement Y as the engagement projections 240, 241.
[0150] From the position according to Fig. 12A bis 12F Connecting part 3 can also be rotated further. In principle, connecting part 3 can be rotated by any angle relative to connecting part 2.
[0151] Under load between the belts 4, 5, the connecting parts 2, 3 automatically move back into the position according to Fig. 1 .
[0152] Attaching or detaching the connecting part 3 to or from the connecting part 2 is also possible in principle in any rotational position.
[0153] In the embodiment according to Fig. 1 bis 12A-12F The connecting device 1 implements a webbing fastener by which straps can be connected to one another. In the connected position, a load direction determined by the straps is essentially directed along the direction of engagement Y.
[0154] In another, in Fig. 13 bis 22A-22D In the illustrated embodiment in the form of a webbing fastener, a first connecting part 2 has a base body 20 on which a receiving opening 23 is formed. A second connecting part 3 can be attached to the first connecting part 2 by inserting a pin element 340, formed on a base section 300 of a base body 30 of the second fastener part 3, into the receiving opening 23 and engaging it via a circumferential engagement section 341 with an arcuate engagement projection 240 on a wall section of the receiving opening 23.
[0155] In the illustrated embodiment, a strap 4 is firmly connected to the base body 30 of the connecting part 3 via a fastening section 301 formed on the base section 300. The strap 4 exits the fastening section 301 at an exit point 306 along a straight exit line (see, for example, Fig. 17A in conjunction with Fig. 18B and 19B ) and is not connected to the base section 300 beyond the exit line 306, but extends freely from the fortification section 301.
[0156] The straight-line exit point 306 can be located radially between the axis of rotation R and the radial location of the engagement projection 240 (relative to the connected position). It is conceivable that the exit point 306 is partially arranged radially within the engagement projection 240, while other areas have a greater radial distance to the axis of rotation R than the engagement projection 240. It is also conceivable that the exit point 306 is arranged entirely radially within the engagement projection 240. Furthermore, it is conceivable that the exit point 306 is arranged entirely radially outside the engagement projection 240, i.e., at a greater radial distance to the axis of rotation R.
[0157] The base section 300 has a circular cylindrical, disc-shaped basic form and forms a base surface 302 on a side facing the connecting part 2.
[0158] The pin element 340, which has a mushroom shape and carries the engagement section 341 extending around the closing direction X and realizing an engagement device 34, projects from the base surface 302. In the illustrated embodiment, the engagement section 341 is thus spatially separated from the base section 300 by being spaced apart from the base section 300 along the closing direction X.
[0159] How this can be seen, for example, from Fig. 18C As can be seen, in the illustrated embodiment the exit line 306 is arranged axially along the direction of engagement Y at approximately the same position as the engagement section 341.
[0160] In the illustrated embodiment, the engagement section 341 has an inclined surface 342 in the form of a conical surface, with which the engagement section 341 runs onto the engagement projection 240 within the receiving opening 23 when the connecting part 3 is attached to the connecting part 2, so that the connecting part 3 is displaced opposite the engagement direction Y to the connecting part 2 and the engagement section 341 is moved past the engagement projection 240 until the engagement section 341 can be brought into engagement with the engagement section 240 in the engagement direction Y.
[0161] The connecting parts 2, 3 each have a magnetic device 21, 31 (see Fig. 14A, 14B ), which are magnetically attractive to each other along the closing direction X and thus magnetically support the attachment of the connecting parts 2, 3 in the closing direction X.
[0162] In the illustrated embodiment, the disc-shaped base section 300 projects radially beyond the engagement section 341 on the pin element 340, as can be seen from Fig. 17A, 17B and 18A, 18B as is evident.
[0163] When attaching the connecting parts 2, 3 to each other, shown in the sequence according to Fig. 19A, 19B bis 22A-22D , the connecting part 3 is brought close to the connecting part 2 in the closing direction X, whereby the connecting part 3 can perform a wobbling movement such that first the engagement section 341 with the inclined surface 342 formed on it comes into contact with the engagement projection 240 in the receiving opening 23, as shown by Fig. 20B as can be seen, and is moved past the engagement projection 240 by sliding, as is the case in the transition from Fig. 20A, 20B towards Fig. 21A, 21B as is evident.
[0164] If the engagement section 341 has been moved past the engagement projection 240, the engagement section 341 comes into engagement with the engagement projection 240 in the engagement direction Y due to magnetic attraction between the magnetic devices 21, 31, so that the connecting parts 2, 3 are in the connected position according to Fig. 22A-22D arrive.
[0165] In the connected position, the engagement section 341 on the pin element 340 engages with the arcuate engagement projection 240 on the wall of the receiving opening 23. On a side facing away from the engagement projection 240, the engagement section 341 faces a blocking section 238 in the form of a projection element extending into the receiving opening 23 in the engagement direction Y. The blocking section 238 thus prevents tangential movement of the pin element 340 in the receiving opening 23 against the engagement direction Y, so that the engagement between the engagement section 341 and the engagement projection 240 is blocked.
[0166] In the connected position, the base section with a circumferential, outer edge section 305 is in conjunction with a support section 233, which is positioned in front of the engagement projection 240 in the engagement direction Y, as shown from Fig. 22B This is evident. The support section 233 thus creates a support in the direction of action Y at the base section 300, so that when a load is applied between the connecting parts 2, 3, forces are absorbed and transferred along the load direction corresponding to the direction of action Y at the support section 233.
[0167] How this is furthermore Fig. 22B As can be seen, in the area of the support section 233, a positive-locking section 234 is formed in the form of a step, on which the base section 300 rests with the edge section 305 in the closing direction X. The step counteracts tilting of the base section 300 and thus of the connecting part 3 relative to the connecting part 2, in order to prevent unintentional loosening of the connecting parts 2, 3 under load.
[0168] As this is shown Fig. 22B in conjunction with Fig. 21B As can be seen, an immersion opening 232 connects to the stage 234, which serves to provide a free space into which the base section 300 can immerse when tilted relative to the connecting part 2, 3, as can be seen from Fig. 21B as is evident.
[0169] If the connecting parts 2, 3 are to be separated from each other, a user can pull on an actuating section in the form of a tab 40 on the back of the connecting part 3 and thus lift the pin element 340 out of the receiving opening 23 on a side facing away from the engagement projection 240, as shown in Fig. 21B This is evident. The base section 300 dips into the immersion opening 232 with a front area facing the support section 233, which facilitates the tilting of the connecting part 3 relative to the connecting part 2 in order to separate the connecting parts 2, 3 from each other.
[0170] The support at level 234 is applied in the connected position, analogous to the initial example according to Fig. 1 bis 12A-12F , preventing tilting under load. A clearance is created via the immersion opening 232 in an area adjoining the step 234 in the opposite direction of engagement Y, into which the base section 300 with its circumferential edge section can immerse when the connecting parts 2, 3 are tilted relative to each other to separate the connection.
[0171] At the in Fig. 13 bis 22A-22D In the illustrated embodiment, the engagement section 341 is not formed on the disc-shaped base section 300, but on the pin element 340 projecting from the base section 300 along the closing direction X, so that the engagement section 341 is spaced apart from the base section 300 along the closing direction X and, in addition, the circumferential edge section 305 of the base section 300 is arranged radially outside the engagement section 241.
[0172] Spatially, the engagement section 341 is thus separated from the base section 300. Functionally, the creation of a positive or force-fit connection via the engagement section 341 is also separate from the support of the base section 300 on the support section 233 and the positive-fit section 234. This can, for example, facilitate the support of the base section 300 for load bearing on the support section 233 and also counteract tilting via the positive-fit section 234, since the base section 300 can provide a comparatively large lever arm for support compared to the engagement section 341.
[0173] In the exemplary embodiment according to Fig. 13 bis 22A-22D The support section 233 is rigidly formed on the base body 20 of the connecting part 2 by a surface section that extends perpendicular to a direction radial to the closing direction X and is curved in an arc around the closing direction X, as shown by Fig. 22B in conjunction with Fig. 16A This is evident. Likewise, the form-fitting section 234 is curved in the shape of a step and thus forms a support for the edge section 305 of the base section 300.
[0174] In a modified version, in Fig. 23A-23C In the illustrated embodiment, an arc-shaped support section 233 extending obliquely to the closing direction X, on the other hand, jointly fulfills the function of the support section 233 and the positive locking section 234 of the embodiment according to Fig. 13 bis 22A-22D The obliquely extended support section 233 of the embodiment according to Fig. 23A-23C forms a support for an inclined edge section 305 of the base section 300 of the connecting part 3, so that via the support section 233 both a support in the engagement direction Y and a support against tilting, i.e. against a movement of the base section 300 in the front area in the closing direction X, is created.
[0175] Otherwise, the exemplary embodiment is according to Fig. 23A-23C identical to the embodiment according to Fig. 13 bis 22A-22D , so reference should also be made to the preceding explanations.
[0176] Fig. 24-50 show exemplary uses of a connecting device 1, as illustrated by the embodiments according to Fig. 1-23C has been described.
[0177] A connecting device 1 can, for example, be used on a bag or backpack, as shown in Fig. 24-31 shown. The connecting device 1 can be used to connect belt ends ( Fig. 24 ,27 , 28 and 31 ), for connecting straps to a bag body ( Fig. 25, 26 and 30 ) or to close the lid of a bag or backpack or to attach an object to the bag or backpack ( Fig. 29 ) serve.
[0178] The connecting device 1 can be used as a fastener for a shoe ( Fig. 32 and 33 ), as a closure for pockets on a textile item, for example a jacket or vest ( Fig. 34 ), or as a closure for a medical bandage ( Fig. 35-37 ) serve.
[0179] The connecting device 1 can be used as a closure for a waist bag ( Fig. 38 ) or for a tool belt ( Fig. 39 ) serve.
[0180] Likewise, the connecting device 1 can serve as a holder for objects, in particular tools or objects, for example an electronic device, a light or the like, on a belt, in particular a tool belt ( Fig. 40 ).
[0181] The connecting device 1 can serve as a fastener for a strap on a musical instrument, for example a guitar ( Fig. 41 ).
[0182] The connecting device 1 can be used, for example, to attach a strap to a bicycle, for example to a luggage rack or a basket on a bicycle ( Fig. 42 ).
[0183] The connecting device 1 can also be used as a fastener for a helmet ( Fig. 43 ) serve.
[0184] The connecting device 1 can provide a strap closure for tying down an object, for example a mat ( Fig. 44 ).
[0185] Furthermore, the connecting device 1 can provide a closure for a strap system for stowing luggage in a vehicle, for example a car ( Fig. 45 ).
[0186] The connecting device 1 can serve as a closure for an adjustment system in the interior of a vehicle, for example for a sunshade ( Fig. 46 ).
[0187] The connecting device 1 can provide a holder for objects on a shelf, for example for key fobs on a key rack ( Fig. 47 ).

[0189] A connecting device 1 can be used as a clasp for a wristwatch ( Fig. 49 ) or a bracelet ( Fig. 50 ) serve.
[0190] In all the applications mentioned, the rotatability of the connecting parts 2 and 3 resolves important aspects of the requirements of the respective application. Conventional plug connectors, as are frequently used for such applications, are not rotatable.
[0191] Other applications are conceivable and possible.
[0192] The underlying idea of the invention is not limited to the illustrated embodiments, but can also be realized in other ways.
