[Technical field]
[0001] The invention relates to a coupling device according to the preamble of claim 1 . [Background technology]
[0002] This type of coupling device comprises a first coupling part having a first base and at least one engagement protrusion firmly attached to the first base. The coupling device further comprises a second coupling part attachable to the first coupling part in a closing direction and having a second base with an engagement part firmly attached to the second base, the engagement part being capable of being brought into engagement with the at least one engagement protrusion of the first coupling part along an engagement direction different from the closing direction such that the engagement part engages with the at least one engagement protrusion of the first coupling part at a coupling position between the first coupling part and the second coupling part. The first coupling part comprises a first magnetic device, and the second coupling part comprises a second magnetic device. The first magnetic device and the second magnetic device interact to be magnetically attracted along the closing direction, thereby assisting the attachment of the first coupling part and the second coupling part to each other.
[0003] In the connecting device, at least one engagement protrusion is firmly formed on the first base of the first connecting part. The second connecting part can be engaged with the at least one engagement protrusion of the first connecting part by engaging the engagement part of the second connecting part with the at least one engagement protrusion of the first connecting part. At this time, the first connecting part and the second connecting part are attached to each other along a closing direction, and the magnetic devices of the connecting parts generate a magnetic attraction force along the closing direction, so that the connecting parts are attracted toward each other along the closing direction. Meanwhile, the engagement part of the second connecting part is engaged with the at least one engagement protrusion of the first connecting part along an engagement direction oriented transversely to the closing direction. In the connecting position, the engagement part engages with the at least one engagement protrusion by form engagement or frictional engagement, so that the connecting parts are held together.
[0004] Here, said engagement direction being different from said closing direction should be understood to mean that said engagement direction is oriented perpendicularly or at an oblique angle to said closing direction, where said engagement direction does not necessarily have to be oriented strictly perpendicular to said closing direction but may extend at an oblique angle to said closing direction, but said engagement direction is not oriented along said closing direction, in particular not against said closing direction.
[0005] In the case of a fastening device known from EP 3 616 553 A1, which comprises two detachable connecting parts, the first connecting part being attached to a second connecting part, which can be connected to one another, one of the connecting parts being provided with a shoe lace, the tension of which can be increased by connecting the connecting parts to one another.
[0006] EP 3 192 388 B1 discloses a fastening device in which a first connecting part has a rigid engaging projection and can be connected to a second connecting part on which a belt or strap is adjustably provided.
[0007] In the case of the mentioned types of connecting devices, it is generally desirable to enable a user-friendly and easy-to-use connection of the connecting parts, preferably with the intention that a positionally generous connection is possible even if the connecting parts are not precisely attached to one another, and that a secure and load-bearing connection is provided at the connecting position of the connecting parts.

[0008] [Patent Document 1] European Patent Application Publication No. 03616553 [Patent Document 2] European Patent No. 03192388 Summary of the Invention [Problem to be solved by the invention]
[0009] The object of the invention is to provide a coupling device in which the coupling parts can be attached to one another simply and easily, and in which they grip each other securely in the coupling position and can be loaded. [Means for solving the problem]
[0010] This object is achieved by the subject matter comprising the features of claim 1.
[0011] According to the document, the first connecting portion has a blocking portion firmly attached to the first base, and the blocking portion is configured to, at the connecting position, block the engagement of the engaging portion with the at least one engaging protrusion from moving in a direction opposite to the engagement direction by interacting with the second connecting portion. At the connecting position, the second connecting portion is rotatable around the closing direction relative to the first connecting portion. During rotation, the engagement of the engaging portion with the at least one engaging protrusion and the blocking of the engagement by the blocking portion are maintained. Here, in order to separate the first connecting portion and the second connecting portion from each other, the second connecting portion is tiltable relative to the first connecting portion so as to release the blocking in the direction opposite to the engagement direction and enable disengagement of the engaging portion with the at least one engaging protrusion.
[0012] The coupling parts are attached to each other along the closing direction, and the attachment of the coupling parts to each other is magnetically assisted by the magnetic devices of the coupling parts, which magnetically attract the coupling parts towards each other and magnetically hold them together in the coupled position during attachment.
[0013] During attachment of the connecting parts, the engagement portion of the second connecting part comes into engagement with the at least one engagement projection of the first connecting part with the engagement direction oriented transversely or obliquely to the closing direction, so that in the connected position there is a form-locking or friction-locking connection between the connecting parts, whereby the connecting parts are held together in a load-bearing manner by the engagement of the engagement portion with the at least one engagement projection.
[0014] At this time, the engagement between the engaging portion of the second connecting portion and the at least one engaging protrusion of the first connecting portion at the connecting position is ensured by the blocking portion of the first connecting portion, which is firmly formed on the first base of the first connecting portion, blockingly interacting with a corresponding portion of the second connecting portion in a direction opposite to the engaging direction, so that the engaging portion cannot move in the direction opposite to the engaging direction by the at least one engaging protrusion unless the blocking is released. In other words, the engaging portion cannot move due to the blocking action of the blocking portion due to the engagement with the at least one engaging protrusion, and the connecting portions are fixed to each other at the connecting position.
[0015] At this time, in the coupled position, the coupling parts are held together by the magnetic action of the magnetic devices in a manner that the blocking portion of the first coupling part prevents the coupling parts from moving together in the direction opposite to the engagement direction, i.e., the coupling parts cannot be separated from each other by a (pure) displacement movement in the direction opposite to the engagement direction.
[0016] On the contrary, to separate the connecting parts from each other, it is necessary to tilt the connecting parts relative to each other and move the second connecting part relative to the first connecting part in a tilting plane spanning the closing direction and the engagement direction, such that the blocking part allows the second connecting part to be moved in the opposite direction to the engagement direction. By tilting the second connecting part relative to the first connecting part, the blocking action of the blocking part can be released, so that the second connecting part can be moved past the blocking part, thereby disengaging the engagement part of the second connecting part from the at least one engagement protrusion of the first connecting part.
[0017] Due to the blocking action of the blocking part firmly attached to the first base of the first connecting part, the second connecting part cannot be moved linearly in the direction opposite to the engagement direction, but rather, in order to separate the connecting parts from each other, the second connecting part needs to be tilted in a tilting plane defined by the closing direction and the engagement direction. In this case, the tilting movement may occur around a predetermined tilting axis. However, the tilting movement may also occur along a curved movement path located in the tilting plane, as a result of which the second connecting part is tilted relative to the first connecting part. In this case, the tilting movement may be combined with a linear movement in the direction opposite to the engagement direction and / or in the direction opposite to the closing direction.
[0018] The connecting parts are tiltable relative to each other to separate them. However, the connection between the connecting parts is not created by a linear closing motion, but rather by tilting the connecting parts relative to each other so that they are attached to each other while swinging and engage with each other. The second connecting part may also be tilted relative to the first connecting part when the connection is created, so that the engaging portion of the second connecting part can be engaged with the at least one engaging protrusion of the first connecting part.
[0019] The second connecting portion is rotatable around the closing direction relative to the first connecting portion at the connecting position. This allows the connecting portions to be attached to each other with a large angular tolerance. This also allows the second connecting portion to be rotated around the first connecting portion even when the connecting portions are at the connecting position. Here, during rotation, the engagement between the engaging portion and the at least one engaging protrusion is maintained. During rotation, the blocking of the engagement by the blocking portion is also maintained. This prevents the connecting portions from being separated from each other even when the connecting portions rotate relative to each other around the closing direction at the connecting position.
[0020] The rotatability between the connecting parts at the connecting position may be such that any desired rotational movement through any desired angle is possible, however it is also conceivable to limit the movement between the connecting parts to a certain rotational angle, for example by means of a stopper, said rotational angle being then preferably greater than 10°, more preferably greater than 20°, very preferably greater than 45° or even greater than 90°.
[0021] The at least one engaging protrusion is formed on the first base of the first connecting portion so as to be strong and undeformable (when a load is applied as intended), so that the engaging protrusion can reliably absorb and release forces when engaging with the engaging portion of the second base. In this case, preferably, the at least one engaging protrusion is integrally formed with the first base of the first connecting portion, which is designed to be generally strong and undeformable.
[0022] In this context, "non-deformable" is intended to be understood to mean that the geometry and material choice of the base are so rigid that the base of the first connecting part on which the engaging projections are formed does not deform under the intended load, i.e. the base is inelastic. For example, the base of the first connecting part may be made of metal or a hard plastic material.
[0023] Similarly, the base of the second connecting portion on which the engaging portion is formed is also strong and undeformable, and for this purpose is made, for example, from metal or a hard plastic material.
[0024] The attachment of the coupling parts to one another is magnetically assisted. For this purpose, the first coupling part comprises a first magnetic device and the second coupling part comprises a second magnetic device. The first and second magnetic devices interact in a magnetically attractive manner in the coupling position and in particular also assist the attachment of the coupling parts to one another. The magnetic devices interact in a magnetically attractive manner along the closing direction, thereby generating a magnetic attraction force along the closing direction, which draws the coupling parts towards one another along the closing direction when attached. Each of the magnetic devices can be formed, for example, by a permanent magnet. However, it is also possible for one of the magnetic devices to be formed by a permanent magnet and the other of the magnetic devices to be formed by a magnetic armature, i.e. a passive magnetic element.
[0025] In one embodiment, the second connecting part can be lifted from the first connecting part in a direction opposite to the closing direction on the side opposite to the at least one engagement protrusion in order to tilt relative to the first connecting part. In the connecting position, the second connecting part is engaged with the at least one engagement protrusion of the first base of the first connecting part by the engagement part firmly formed on the second base, and this engagement is performed in a front area of the second connecting part with respect to the engagement direction. In the connecting position, the second connecting part can be lifted from the first connecting part in a rear area with respect to the engagement direction in a direction opposite to the closing direction, so that the blocking action of the blocking part of the first connecting part can be released by tilting the second connecting part relative to the first connecting part, and the second connecting part can be moved relative to the blocking part of the first connecting part to disengage the engaging part from the at least one engagement protrusion in a direction opposite to the engagement direction.
[0026] For ease of handling by the user, the second connecting part may comprise, for example, an actuating part which can be grasped by the user in order to tilt the second connecting part relative to the first connecting part. The actuating part may, for example, be formed by a tab in the rear region of the second connecting part, by which the user can lift the second connecting part in the rear region from the first connecting part in the direction opposite to the closing direction by pulling the tab. However, the actuating part may also be formed, for example, by a concave grip or another gripping part, by which the user can grasp the second connecting part relative to the first connecting part.
[0027] In one embodiment, the at least one engagement protrusion is curved in an arc shape centered on the closing direction. That is, when one (single) engagement protrusion is provided, the engagement protrusion extends in an arc shape centered on the closing direction. When multiple engagement protrusions are provided, each engagement protrusion may extend in an arc shape centered on the closing direction, for example. In addition to or in addition to this, the engagement protrusions may be arranged adjacent to each other along a circumferential direction oriented around the closing direction. That is, the engagement protrusions are arranged adjacent to each other along an arc-shaped line and jointly engage with the engagement portion of the second connecting portion when the connecting portions are in the connecting position.
[0028] The at least one engagement protrusion extends at an angle of less than 180°, preferably less than 150°, about the closing direction such that the engagement portion can be brought into engagement with the at least one engagement protrusion in the engagement direction.
[0029] Preferably, the at least one engagement protrusion forms an undercut with respect to the closing direction, i.e., the at least one engagement protrusion is protruded from a corresponding portion of the first connecting portion so as to cross the closing direction, and is undercut with respect to the closing direction.
[0030] The undercut may then be formed by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.
[0031] Similarly, preferably, the engaging portion of the second connecting portion forms an undercut with respect to the closing direction, i.e., the engaging portion is undercut with respect to the closing direction by protruding from a corresponding portion of the second connecting portion so as to cross the closing direction.
[0032] The undercut may then also be formed by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.
[0033] In one embodiment, the engagement portion extends in a circumferential direction around the closing direction. In this case, the engagement portion may be provided on a pin element or the like and may protrude from the pin element so as to cross the closing direction.
[0034] For example, the engaging portion is formed rotationally symmetrical with respect to the closing direction, and thus, it is possible to bring the engaging portion into engagement with the at least one engaging protrusion of the first connecting portion at any desired rotation position of the second connecting portion relative to the first connecting portion, and to bring about engagement between the engaging portion and the at least one engaging protrusion at any desired rotation position of the second connecting portion relative to the first connecting portion, so that the connecting portions can be rotated relative to each other without disengaging the engaging portion from the at least one engaging protrusion.
[0035] In one embodiment, the second substrate of the second linking portion comprises a base.
[0036] In this case, in one embodiment, the base may be configured to form the engagement portion such that the engagement portion for engaging with the at least one engagement protrusion of the first connecting portion is formed on the base, for example, on a peripheral edge portion of the base.
[0037] In other embodiments, the engagement portion is spaced apart from the base along the closing direction, i.e., the engagement portion is spatially separated from the base, e.g., by the base extending along a first plane and the engagement portion extending along a second plane spaced apart from the first plane along the closing direction.
[0038] When the engaging portion is spatially separated from the base, the engaging portion is formed, for example, on a pin element protruding from the base along the closing direction, and the engaging portion forms an undercut by protruding from the pin portion along the engaging direction, whereby the engaging portion can be engaged with the at least one engaging protrusion of the first connecting portion to generate a connection by form engagement or frictional engagement.
[0039] The engagement portion may, for example, be formed circumferentially on the pin element, thereby providing a mushroom-shaped engagement element capable of entering into engagement with the at least one engagement projection of the first connecting portion at any desired rotational position to connect the connecting portions together and hold the connecting portions together in the connecting position.
[0040] When the engaging portion is spatially separated from the base, the base may extend radially in the closing direction more than the engaging portion, i.e. may protrude radially beyond the engaging portion. Thus, the engaging portion is located radially inward, whereas the outer edge of the base is located radially outward of the engaging portion. This allows a good support of the second connecting portion by the first connecting portion via the base when the connecting portions are in their connecting positions.
[0041] In one embodiment, the base is, for example, in the form of a disk, in which case the base may, for example, have a cylindrical basic shape with a circular cross section.
[0042] The base may be formed with a fastening portion for connecting, for example, a strap or belt to the second connecting portion.
[0043] In one embodiment, the base of the second base of the second connecting portion includes an edge portion. In contrast, the first connecting portion has a support portion firmly formed on the first base, and in the connecting position, in addition to the engagement between the engagement portion and the at least one engagement protrusion, the edge portion is supported by the support portion, thereby absorbing the load along the engagement direction. The edge portion may be formed, for example, in a front region of the base. In one embodiment in which the base portion is cylindrical, the edge portion may be configured to go around the base in a circumferential direction. The support portion is formed in a front region of the first connecting portion with the engagement direction as a reference. Thereby, the support portion can support the base in the engagement direction. In other words, when the load of the second connecting portion is applied to the first connecting portion in the engagement direction, the edge portion is pressed against the support portion, and the edge portion is supported by the support portion. Thus, in the connecting position, the base is able to come into contact at the edge with the support portion of the first base of the first connecting part so that load forces can be transferred from the second connecting part to the first connecting part.
[0044] It is then conceivable that in the coupling position, the edge is always in contact with the support in the engagement direction. As a variant, in the unloaded position, the edge does not support the support in the engagement direction, but rather comes into contact with the support only when the coupling parts are loading each other.
[0045] Advantageously, the support and the support of the edge of the base by the support allows a force to be transferred from the second connecting part to the first connecting part. For example, in one embodiment in which the connecting device is a webbing fastener, the load direction acting between the connecting parts during intended use of the connecting device may preferably be oriented with a directional vector component at least in the engagement direction. That is, the load direction extends at least approximately in the engagement direction or obliquely to the engagement direction, and therefore at least also in the engagement direction, i.e. with a directional vector component in vector decomposition. Thus, under load, the second connecting part applies a load to the first connecting part in the engagement direction, i.e. in the direction of engagement with the at least one engagement protrusion firmly formed on the first connecting part (at least in combination). Since the edge of the base then comes into supporting contact with the support, the force acting in the engagement direction is guided away by the contact of the edge at the support. At this time, the at least one engaging protrusion provides support particularly along the closing direction, thereby ensuring that the connecting parts grip each other, while the load force in the engaging direction is mainly absorbed and guided away via the support portion.
[0046] In one embodiment, the support and the edge are each curved in an arc in a cross-sectional plane perpendicular to the closing direction. In one embodiment, the base is cylindrical, and the edge of the base orbits in a circle centered on the closing direction. The curvature of the support corresponds to the curvature of the edge of the base, so that the base can come into supporting contact with the support of the first connecting portion at the connecting position.
[0047] In one embodiment, the support portion is spaced apart from the at least one engagement protrusion when viewed along the closing direction, and the support portion may extend above or below the at least one engagement protrusion when viewed along the closing direction.
[0048] Additionally or alternatively, the support portion may be spaced apart from the at least one engagement protrusion when viewed along the engagement direction. That is, the support portion is located at a different position from the at least one engagement protrusion with respect to the engagement direction. Specifically, the support portion may be attached upstream of the at least one engagement protrusion in the engagement direction so as to be located radially outward of the at least one engagement protrusion. This allows the base portion to come into contact with the support portion with a desired leverage when a load force acts between the connecting portions, and the support portion can provide a desired support.
[0049] In one embodiment, the support is formed by a surface oriented parallel or obliquely to the closing direction, the support being rigidly formed on the first base of the first connecting part, such that when a load is applied, the support of the first connecting part comes into contact with the base of the second connecting part, allowing the load force acting in the engagement direction to be absorbed and guided away in a desired manner.
[0050] In one embodiment, the base includes a base surface and the first base includes a bottom surface, the base surface and the bottom surface each extending perpendicular to the closing direction, the base surface of the base of the second connecting portion and the bottom surface of the first base of the first connecting portion facing each other at the connecting position.
[0051] In the coupling position, for example, there may be contact between the base surface and the bottom surface, such that the base surface and the bottom surface are caused to slide against each other when the coupling parts rotate relative to each other around the closing direction.
[0052] However, this is not required: it is also conceivable that there is a distance between the base surface and the bottom surface (i.e., no contact) at the connection location.
[0053] In one embodiment, the base is tiltable with respect to the first connecting portion about a tilt axis perpendicular to the closing direction and the engagement direction in order to tilt the connecting portions relative to each other. That is, the base is tilted with respect to the first base of the first connecting portion about the tilt axis, so that the connecting portions are tilted to separate from each other. In this case, the tilt axis may be determined by a contact line between the base and the first base. However, it is also conceivable that the tilt axis corresponds to a virtual straight line extending within or outside the base, which corresponds to a straight line that is a rotation center of the base when the connecting portions are tilted relative to each other.
[0054] In one embodiment, the first base includes an entrance opening into which a portion of the base can enter when the second connecting portion is tilted relative to the first connecting portion in the closing direction. Specifically, the entrance opening can be formed in a front region of the first base (with respect to the engagement direction) and can be formed, for example, as a recess in the first base. The base can enter the entrance opening, particularly at a front edge, when the connecting portions are tilted relative to each other (during connection or disconnection).
[0055] The entry opening may be formed, for example, as a recess in the bottom surface of the first base. In this case, the entry opening may be in contact with the bottom surface, but is recessed in relation to the bottom surface, and therefore recedes along the closing direction. Specifically, the entry opening may extend below the at least one engaging protrusion, so that a space may be provided in the region of the at least one engaging protrusion into which the base of the second connecting part can enter at its edge when the connecting parts are attached to each other to close the connecting device, or when the connecting parts are separated from each other to open the connecting device.
[0056] However, when the engagement portion is formed spatially separated from the base, the entry opening may be formed, for example, as a recess radially outward of the at least one engagement protrusion to provide space for the edge of the base to enter.
[0057] In general, the play between the engaging portion of the second connecting portion and the at least one engaging protrusion of the first connecting portion allows the connecting portions to be easily connected or disconnected by tilting relative to each other. As a modified example, a space may be provided to provide play and allow the engaging portion to be tilted relative to the at least one engaging protrusion, for example, by an oblique angle or an R portion of the engaging portion.
[0058] In particular, when the engagement portion is formed on the peripheral edge of the base, the entrance opening is formed, for example, as a recess in the bottom surface of the first connecting portion and is in contact with the bottom surface in the region on the support portion side. The entrance opening can be, for example, one that extends between the support portion and the bottom surface.
[0059] When the engagement portion is formed on the pin below the base and the base protrudes radially beyond the engagement portion, preferably the access opening is formed in the first base radially outside the at least one engagement protrusion.
[0060] The access opening may be configured as a recess or as a through opening in the first substrate.
[0061] In one embodiment, the first base includes a form-engaging portion that resists tilting of the second connecting portion relative to the first connecting portion by disposing the base at the connecting position between the first connecting portion and the second connecting portion. Specifically, the form-engaging portion is formed in a front region of the first base with respect to the engagement direction, and is firmly formed on the first base. Since the base is supported by the form-engaging portion, particularly in the closing direction, tilting of the second connecting portion relative to the first connecting portion is at least difficult due to support by the form-engaging portion.
[0062] During tilting to separate the connecting parts from each other, the second base is released from the interaction with the form-engaging part of the first base by a slight movement in the opposite direction to the engagement direction within the range of play. In this case, the play between the second connecting part and the blocking part of the first connecting part may allow a (slight) displacement movement of the second connecting part in the opposite direction to the engagement direction, or the play between the second connecting part and the at least one engagement protrusion may allow a (slight) tilt movement and a subsequent displacement movement of the second connecting part in the opposite direction to the engagement direction. For example, the second base is guided away from the form-engaging part formed in a step or other manner by a movement within the range of play, so that the second base moves out of the effective connection with the form-engaging part. After that, the connecting parts can be tilted relatively (stronger), so that the connecting parts can be separated from each other.
[0063] A depth of the engagement protrusion, measured along the engagement direction, may then be greater than a depth of a support surface provided by the form-engagement portion, measured along the engagement direction, such that a further movement against the engagement direction does not cause the engagement portion of the second connecting part to disengage from the at least one engagement protrusion of the first connecting part unless a third region is first guided away from the form-engagement portion.
[0064] The form-fitting portion may be formed, for example, by a step on which the base is placed at the coupling position. In this case, specifically, the form-fitting portion may have a surface portion oriented perpendicularly or obliquely to the closing direction to support the base.
[0065] In other embodiments, the form-locking portion may be formed in the support portion as an engagement opening, for example in the form of a notch, etc., which supports the base perpendicular to the engagement direction, i.e. along the closing direction, so that in the connected position, when a load is applied, the connecting parts cannot easily tilt undesirably relative to each other, but are instead supported by the form-locking portion against (undesirable) tilting.
[0066] In one embodiment, the form-locking portion is spaced apart from the at least one engagement protrusion when viewed along the closing direction, and may extend above or below the at least one engagement protrusion when viewed along the closing direction.
[0067] Additionally or alternatively, the form-engaging portion may be spaced apart from the at least one engaging protrusion when viewed along the engagement direction. That is, the form-engaging portion is located at a different position from the at least one engaging protrusion with respect to the engagement direction. Specifically, the form-engaging portion may be attached upstream of the at least one engaging protrusion in the engagement direction, that is, located radially outward of the at least one engaging protrusion. This allows the base to come into contact with the form-engaging portion with a desired leverage when a load force acts between the connecting parts, and the form-engaging portion can provide a desired support against the relative tilting of the connecting parts.
[0068] In one embodiment, the second connecting portion has a blocking element that is firmly attached to the second base and interacts with the blocking portion of the first connecting portion. The blocking element may be formed on the base, for example, and may protrude from the base along the closing direction. In the connecting position, the blocking element interacts with the blocking portion of the first connecting portion, thereby blocking the relative movement of the connecting portions in the opposite direction to the engagement direction. However, if the connecting portions are tilted relative to each other, the blocking element is lifted above the blocking portion to release the blocking, and the connecting portions are moved relative to each other by tilting in the opposite direction to the engagement direction to disengage the engagement portion of the second connecting portion from the at least one engagement protrusion of the first connecting portion, thereby enabling the connecting portions to be separated from each other.
[0069] For example, the blocking element may be formed cylindrically and may be circular in a cross-sectional plan view perpendicular to the closing direction, in which the blocking element is rotatable around the closing direction relative to the blocking part at the connecting position, so that the connecting parts can be relatively rotatable, but the blocking of the engagement of the engaging part with the at least one engaging protrusion is maintained during the rotation.
[0070] In one embodiment, the first base includes a recess at least partially defined by the blocking portion. The blocking element is disposed in the recess such that, in the coupling position, the engagement of the engaging portion with the at least one engaging protrusion is blocked from moving in a direction opposite to the engagement direction. The recess may be formed, for example, as a depression in a bottom surface of the first base of the first coupling part. That is, the recess is formed in the bottom surface. When the coupling parts are attached to each other, the blocking element is brought into engagement with the recess, and the second coupling part is held by the at least one engaging protrusion of the first coupling part through the engagement.
[0071] In one embodiment, the recess (in a cross-sectional plane perpendicular to the closing direction) is defined by at least one boundary wall realizing the blocking portion and extending along a circular arc. The recess may, for example, have a circular basic shape along which the at least one boundary wall extends in an arc about a (virtual) circle centered on an axis.
[0072] For example, the recess is defined by two arcuate boundary walls which together form the blocking part and receive the blocking element of the second connecting part between them in the connecting position to block movement of the second connecting part relative to the first connecting part in the direction opposite to the engagement direction, the at least one boundary wall being arranged, for example, perpendicular to the bottom surface, to provide a support surface for the blocking element, so that under load the blocking element is supported by the boundary wall and cannot move relative to the first connecting part.
[0073] In one embodiment, the blocking part has a ramp which is configured to guide the blocking element in a direction opposite to the engagement direction when the second connecting part is tilted relative to the first connecting part. For example, when the connecting parts are tilted relative to each other, the blocking element of the second connecting part can come into contact with the ramp and can be moved over the blocking part by climbing up the ramp. In other words, such a ramp can facilitate the separation of the connecting parts from each other.
[0074] In one embodiment, the at least one engagement protrusion has a sliding ramp, e.g. a guide ramp for guiding the coupling parts when attached to each other so that the coupling parts can be easily, preferably almost automatically, engaged with each other. Preferably, the sliding ramp is configured such that the second coupling part, when attached to the first coupling part, is guided on the at least one engagement protrusion along the closing direction so as to be displaced from the first coupling part in the direction opposite to the engagement direction, so that the second coupling part passes over the at least one engagement protrusion. After the second coupling part passes over, it can be engaged with the at least one engagement protrusion of the first coupling part in the engagement direction. That is, the second coupling part is guided with respect to the first coupling part so as to pass over the at least one engagement protrusion by sliding on the at least one engagement protrusion. When the engagement part of the second coupling part has passed over the at least one engagement protrusion, it can be engaged with the at least one engagement protrusion of the first coupling part in the engagement direction.
[0075] In one embodiment, the webbing fastening comprises a connecting device according to any one of the previous claims, in particular, the second connecting part being capable of being connected with a strap or belt, which strap or belt may be fixedly and non-adjustably (but possibly also adjustable) provided on the second connecting part.
[0076] The first connecting portion may also be connected to a strap or belt, but may also be fixedly attached to a corresponding assembly, for example a textile object or other object.
[0077] In one embodiment, the first connecting part in use of the connecting device on a webbing fastening has two engagement protrusions spaced apart transverse to the closing direction and transverse to the engagement direction such that at the connecting position of the first connecting part and the second connecting part the strap or belt can be guided between the engagement protrusions, i.e. the engagement protrusions provide support of the second connecting part to the first connecting part on both sides of the strap or belt as the strap or belt is received between the engagement protrusions.
[0078] In another application, an object fastening device for fastening an object to an assembly may comprise a coupling device of the described kind, where the object may for example be provided on one of the coupling parts, for example being integrated in said coupling part, whereas the other of said coupling parts is provided on said assembly, i.e. the coupling of said coupling parts allows said object to be fixed to said assembly.

[0082] In one exemplary embodiment shown in Figures 1 to 12A-12F, the connecting device 1 comprises a first connecting part 2 (referred to as the female part) and a second connecting part 3 (referred to as the male part) attached to the first connecting part 2.
[0083] In general, the connecting parts 2, 3 can be attached to each other along a closing direction X and each of the connecting parts 2, 3 comprises a magnetic device 21, 31 in the form of a permanent magnet (or one in the form of a permanent magnet and a second in the form of a magnetic armature) that interacts in a magnetically attractive manner to draw the connecting parts 2, 3 towards each other along the closing direction X.
[0084] It should be noted that the coupling parts 2, 3 may also be attached in a direction offset from the closing direction X, for example obliquely to the closing direction X. The magnetic devices 21, 31 interact magnetically in the closing direction X, drawing the coupling parts 2, 3 towards each other along the closing direction X.
[0085] As can be seen from the exploded views of Figures 2A and 2B and the separated views of Figures 3A and 3B and 4A-4C, the first connecting part 2 has a base body 20 forming a receiving opening 23 for receiving the second connecting part 3. The base body 20 is provided with a webbing receiving portion 22 in the form of a web and an adjacent opening, to which the belt or strap 5 can be or is fastened. Opposite the receiving opening 23, the base body 20 forms a fastening opening 25 for receiving the magnetic device 21.
[0086] The receiving opening 23 is formed as a recess in the base body 20. In the receiving opening 23, a bottom surface 230 in the form of a flat surface extending perpendicular to the closing direction X is formed, and the second connecting part 3 can be inserted into the receiving opening 23 and brought into surface contact with the bottom surface 230 in order to bring about the connection between the connecting parts 2, 3.
[0087] A recess 231 in the form of a depression is formed in the bottom surface 230. As will be described later, in the connecting position of the connecting elements 2, 3, a blocking element 303 of the base 300 of the second connecting part 3 engages in said recess.
[0088] The receiving opening 23 is delimited at its front end by a support portion 233 which supports and absorbs loads of the second connecting part 3 in the connecting position. Between the support portion 233 and the bottom surface 230, an access opening 232 is formed, which, as can be seen for example in Fig. 10B and will be described later, allows an edge 305 of the base 300 of the second connecting part 3 to enter the access opening 232 when the connection is made or even when the connection is separated, thereby facilitating the creation or separation of the connection between the connecting parts 2, 3.
[0089] The access opening 232 is recessed into the bottom surface 230 and borders the bottom surface 230 such that it is located between the support portion 233 and the bottom surface 230. At the transition from the access opening 232 to the bottom surface 230, a beveled transition surface 237 is formed to guide the second connection part 3 when making the connection and when breaking the connection.
[0090] The rigidly formed base 20 is provided with engaging projections 240, 241 rigidly formed with the base 20 at two lateral undulations 242, 243, which are located above the bottom surface 230 as viewed along the vertical direction H oriented along the closing direction X, and which generate a connection between the connecting parts 2, 3 by form-fitting or frictional engagement at the connecting position. The engaging projections 240, 241 are spaced apart from each other along the transverse direction Q. The engaging projections 240, 241 jointly form an engaging device 24 that enables engagement with the second connecting part 3 by form-fitting or frictional engagement. As will be described later, at the connecting position, the base 300 of the second connecting part 3 has an engaging portion 341 formed on the base 300 received between the engaging projections 240, 241 and the bottom surface 230, and an edge portion 305 is supported by the support portion 233. This ensures that the connecting portions 2, 3 are held together securely and reliably.
[0091] The engaging protrusions 240, 241 are formed with sliding inclines 244, 245 which are inclined obliquely in the vertical direction H, and when the connecting parts 2, 3 are attached to each other along the closing direction X, they cause sliding in the opposite direction to the engaging direction Y of the second connecting part 3.
[0092] The recess 231 is laterally delimited by arc-shaped boundary walls 236. The boundary walls 236 together realize a blocking portion of the first connecting part 2 and are oriented perpendicular to the bottom of the recess 231 and also to the bottom surface 230. The boundary walls 236 extend in the form of an arc around a central axis B of the recess 231 oriented along the normal direction N of the bottom surface 230.
[0093] Between the boundary walls 236, a riser ramp 235 is formed. The riser ramp is provided behind the support portion 233 in the recess 231 and provides a sliding surface for facilitating the sliding of the blocking element 303 into and out of the recess 231.
[0094] The bottom surface 230 extends flat along a plane perpendicular to the normal direction N.
[0095] As is apparent from the exploded views of Figures 2A and 2B and the separated views of Figures 5A, 5B and 6A to 6C, the second connecting portion 3 is fixedly connected to the strap or belt 4. The second connecting portion 3 has a base 30 on which the strap or belt 4 is fixedly and non-adjustably mounted by being disposed in a webbing receiving portion 32 formed between a base portion 300 and a fastening portion 301. Thus, the strap or belt 4 is fixedly mounted to the base portion 30.
[0096] The base 30 may be integrally formed as a one-piece piece with the base 300 and fastening portion 301, for example by plastic injection molding, into which the strap or belt 4 is partially insert molded and thus non-adjustably fixedly connected to the base 30.
[0097] The base 300 has a cylindrical basic shape, the side facing the first connecting part 2 (when said connection is generated) forming a flat extending base surface 302. The base surface 302 comes into surface contact with the bottom surface 230 of the receiving opening 23 when the second connecting part 3 is attached to the first connecting part 2.
[0098] From the base surface 302 projects a blocking element 303 of circular cross section concentric with the cylindrical base 300 and engages in a recess 231 in the bottom surface 230 of the base 20 of the first connecting part 2 .
[0099] In the blocking element 303 a fastening opening 35 is formed for receiving a magnetic device 31 of the second connecting part 3, for example in the form of a permanent magnet or the like, in which the magnetic device 31 is fastened.
[0100] The base 300 forms the engagement device 34 of the second connecting part 3, including an engagement portion 341. When the connection is generated, the engagement portion 341 interacts with the engagement projections 240, 241 of the engagement device 24 of the first connecting part 2 and passes under the engagement projections 240, 241, thereby generating a connection between the connecting parts 2, 3 by form-fit or frictional engagement.
[0101] In the illustrated exemplary embodiment, the engagement portion 341 is formed by a peripheral edge of the base 300 that protrudes radially beyond the fastening portion 301 to form an undercut. The undercut allows the engagement portion 341 to enter into engagement with the engagement projections 240, 241 of the first connecting portion 2, which also form an undercut, thereby connecting the connecting portions 2, 3 to each other.
[0102] A connecting method of the connecting device 1 will be described with reference to FIG. 7A and FIG. 7B to FIG. 11A to FIG. 11D.
[0103] The connecting parts 2, 3 are attached to each other substantially along the closing direction X, while the magnetic devices 21, 31 interact magnetically along the same direction, drawing the connecting parts 2, 3 towards each other by magnetic attraction. The connecting parts 2, 3 can then be manually brought closer to each other, but after a certain proximity, the magnetic attraction force automatically draws the connecting parts 2, 3 into engagement and thereby causes the creation of said connection of the connecting device 1. Thus, an inaccurate attachment of the connecting parts 2, 3 to each other is sufficient, after which the connection is created very substantially automatically.
[0104] As is clear from Figures 7A and 7B, when the connecting parts 2, 3 are moved toward each other, the base part 300 of the base body 30 of the second connecting part 3 moves from above along the closing direction X into contact with the engaging projections 240, 241, as is clear from Figures 8A and 8B. At this time, the inclined sliding ramps 244, 245 formed on the engaging projections 240, 241 allow the base part 300 to slide on the engaging projections 240, 241 along the sliding direction A, and as can be seen in Figure 8B, the rear edge 304 of the base part 300 can enter into contact with the bottom surface 230 of the receiving opening 23 of the first connecting part 2. This allows the base part 300 to be guided and slid along the bottom surface 230 without the blocking element engaging too early.
[0105] Once the base 300 has finished sliding along the engagement projections 240, 241, i.e., once the base 300 has passed over the engagement projections 240, 241 in the closing direction X, as is evident from Figures 9A-B and 10A-B, the engagement portions 341 formed on said circumferential edge of the base 300 slide into engagement with the engagement projections 240, 241 in the engagement direction Y, assisted by the magnetic attraction of the magnetic devices 21, 31. This movement (approximately) along the engagement direction Y is magnetically assisted, but the engagement action can also be assisted by a load force (delivered via the strap or belt 4).
[0106] When the engagement portion 341 enters into engagement with the engagement protrusions 240, 241 in the engagement direction Y, the blocking element 303 slides into the recess 231 of the receiving opening 23 of the first connecting part 2, as is evident in the transition from Figures 10A and 10B to Figures 11A-11D.
[0107] In the connection position shown in Figures 11A to 11D, as is particularly clear from the cross-sectional view of Figure 11B, the blocking element 303 is arranged in the recess 231, and the base 300 is arranged in a planar manner on the bottom surface 230 within the accommodating opening 23 of the first connecting part 2 by the base surface 302 formed on the base 300.
[0108] In said connected position, the base 300 is arranged such that it faces and is supported by the support 233 with its (front) edge 305. If a force is transmitted to the second connecting part 3 via the strap or belt 4, this force is absorbed and guided away by the supporting contact of the base 300 at the support 233.
[0109] As is clear from Figures 11C and 11D, at this time, the support portion 233 is curved in an arc shape according to the curvature of the cylindrical base portion 300 around the closing direction X so that contact exists between the edge portion 305 of the base portion 300 and the support portion 233 along an arc-shaped support line or support surface.
[0110] At this time, the support portion 233 is provided so that its central portion is between the engaging protrusions 240, 241 when viewed along the transverse direction Q, and is separated from the engaging protrusions 240, 241 at the central portion along the engaging direction Y. At this time, the support portion 233 extends in an arc shape below the engaging protrusions 240, 241 and beyond the engaging protrusions 240, 241 in the cross-sectional plane of FIG. 11D, so that the base 300 is supported in a planar manner at the center between the engaging protrusions 240, 241 and even directly in the region of the engaging protrusions 240, 241.
[0111] In the connecting position, the strap or belt 4 is located at the connecting part 3 approximately horizontally with or below the engaging protrusions 240, 241 of the connecting part 2. As a result, even if the force of the strap or belt is transmitted through the strap or belt 4, the engaging protrusions 240, 241 fix the position of the connecting part 3 on the connecting part 2, particularly along the vertical direction H, so that the connecting part 3 cannot tilt within the receiving opening 23 or only a small tilting movement can occur.
[0112] When a load acts between the connecting parts 2 and 3 at the connecting position, the strap or belt 4 is disposed between the undulating parts 242 and 243, that is, between the engaging protrusions 240 and 241. Therefore, when a force is transmitted through the strap or belt 4, the engaging protrusions 240 and 241 provide symmetrical support with respect to the strap or belt 4.
[0113] In said coupled position, the magnetic devices 21, 31 interact magnetically in an attractive manner, thereby holding the coupling parts 2, 3 in said coupled position.
[0114] Furthermore, the engagement of the blocking element 303 with the recess 231 prevents the coupling parts 2, 3 from relative tangential displacement in the direction opposite to the engagement direction Y. In the coupling position, the blocking element 303 is disposed in the recess 231 so as to be accommodated between the boundary walls 236 that realize the blocking portion, and is in blocking contact with the arc-shaped boundary walls 236, so that the blocking element 303 cannot be moved in the direction opposite to the engagement direction Y relative to the boundary walls 236.
[0115] Due to the rotationally symmetric shape of the blocking element 303 and the cylindrical shape of the base 300, the connecting part 3 in said connecting position can be rotated along the circumferential direction U (see Figure 1) within the receiving opening 23 of the connecting part 2 at any desired angle around the rotation axis 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.
[0116] This rotatability also allows the connecting parts 2, 3 to be attached to each other in any desired angular position, and when a load is applied via the strap or belt 4, the connecting parts 2, 3 are aligned with each other so that the strap or belt 4 is located between the engagement projections 240, 241, and thus the connecting part 3 is supported symmetrically on the connecting part 2. This rotatability allows the connecting parts 2, 3 to be attached to each other in a positionally generous manner, making the creation of the connection simple and easy.
[0117] 10A to 10C, when the base 300 slides into the entrance opening 232 formed to be concave with respect to both the bottom surface 230 and the recess 231, the front edge 305 passes under the engagement protrusions 240, 241. The edge 305 enters the entrance opening 232, which allows the blocking element 303 to slide into the recess 231 and may cause the engagement portion 341 formed on the base 300 to engage with the engagement protrusions 240, 241. In addition, the angle range of the opening force applied to the operating portion 40 (tab) is expanded, making it possible to prevent the edge 305 from getting stuck during opening.
[0118] 11B, in the connected position, the front edge 305 of the base 300 is placed on a form-engaging portion in the form of a step 234 formed between the entrance opening 232 and the support portion 233, and is arranged horizontally with the bottom surface 230. The contact of the base 230 with the step 234 provides additional support to the connecting portion 3 against tilting relative to the connecting portion 2.
[0119] As a variant, the shape-engaging portion may be formed by, for example, a notch or the like in the support portion 233, in which the base 300 engages with the edge portion 305, thereby supporting the base 300 at the support portion 233 so as to resist tilting associated with movement of the edge portion 305 downward in the closing direction X at the support portion 233.
[0120] In the connection position of Figs. 11A-11D, the form-engagement part in the form of a step 234 resists tilting, especially when a load is applied to the strap or belt 4. That is to say, in the connection position, the second connection part 3 rests with its base 30 on a first area formed by a rear area (with reference to the engagement direction Y) on the bottom surface 230 of the base 20 of the first connection part 2. In contrast, in a second area in contact with the engagement direction Y formed by the upper area of the entrance opening 232, the second base 30 of the second connection part 3 does not abut against the first base 20 of the first connection part 2. The second base 30 rests on the step 234 by a third area formed by the front edge 305 of the base 300 in contact with the second area in the engagement direction Y. Thus, in the connection position, support is provided in the form of a two-point support with a gap in the area of the entrance opening 232 between them.
[0121] In the loaded position, the base 300 bears the load with its forward edge 305 against the support 233 and so remains in contact with the step 234 in a self-reinforcing manner.
[0122] When the connecting parts 2, 3 are separated from each other, the movement sequence of Figures 7A and 7B to Figures 11A-11D proceeds substantially in reverse. In particular, to separate the connecting parts 2, 3, the user can grab an actuation part in the form of a tab 40 (formed by a protruding part of the strap or belt 4) on the rear side of the connecting part 3, opposite the engagement projections 240, 241, and thereby lift the connecting part 3 at its rear end from the bottom surface 230, thereby tilting it out of the connecting position of Figures 11A-11D relative to the connecting part 2. This causes the base 300 to slide at its front edge 305 out of the step 234 and the blocking element 303 to be lifted out of the recess 231, as is clear from Figures 10A and 10B. In this way, the blocking between the connecting parts 2, 3 in the direction opposite to the engagement direction Y is released, allowing the connecting part 3 to be pulled out of engagement from the connecting part 2 in the direction opposite to the engagement direction Y, thereby allowing the connecting parts 2, 3 to be disconnected from each other.
[0123] At this time, the tilting is performed in a tilting plane perpendicular to the bottom surface 230, i.e., spanning the closing direction X and the engagement direction Y. At this time, the tilting occurs approximately about the tilting axis K (see Figs. 10A and 10B), so that the connecting part 3 performs a rotational movement in a tilting plane perpendicular to the tilting axis K, whereby the blocking element 303 is lifted out of the recess 231, and the connecting parts 2, 3 can be relatively moved in the direction opposite to the engagement direction Y and thereby separated from each other.
[0124] In particular, when the connection between the connecting parts 2, 3 is to be released when no load is applied to the connecting device 1, the connecting parts 2, 3 are tilted relatively, particularly in the direction opposite to the engagement direction Y, so that, as is clear from Fig. 10B, the front edge 305 (forming the third region) of the base 300 slides from the step 234 and enters the region of the entry opening 232. This allows the connecting parts 2, 3 to be easily and simply separated from each other when tilted by the actuating part 40, since the form-engagement part formed by the step 234 no longer resists the tilting (thereafter).
[0125] 12A-12F show the coupling device 1 in a position where the second coupling part 3 is rotated relative to the first coupling part 2. Here, the second coupling part 3 can be mounted in (any desired) rotational position relative to the first coupling part 2, and the engagement parts 341 of the second coupling part 3 can be brought into engagement with the engagement projections 240, 241 of the first coupling part 2 in any desired rotational position. The second coupling part 3 in said coupling position is rotatable along the circumferential direction U about the rotation axis R relative to the first coupling part 2, with the engagement of the engagement parts 341 with the engagement projections 240, 241 being maintained and the blocking element 303 engaged with the recess 321.
[0126] When a strap force or belt force acts between the straps or belts 4, 5 at the connecting position of the connecting device 1 under load, the strap or belt 4 is disposed between the engagement projections 240, 241, as is clear from Fig. 1. In this case, the engagement projections 240, 241 are located to the sides of the strap or belt 4, so that the strap or belt 4 extends between the engagement projections 240, 241 (as viewed along the transverse direction Q from the engagement projection 240 to the engagement projection 241).
[0127] 12A to 12F, when the second connecting portion 3 is rotated relative to the first connecting portion 2 along the circumferential direction U about the rotation axis R, as is particularly clear from Figures 12B and 12D, the strap or belt 4 is flexibly deformed to bend and slacken, thereby being able to extend beyond one of the engaging protrusions 240, 241. During rotation, the strap or belt 4 is deformed by sliding onto one of the engaging protrusions 240, 241 (depending on the direction of rotation), and is able to be moved beyond that engaging protrusion 240, 241.
[0128] 1 together with, for example, FIG. 6C, the strap or belt 4 emerges from the fastening part 301 above the base 300 with an exit line 306 that is curved according to the cylindrical shape of the fastening part 301. At this time, beyond the exit line 306, i.e. outside the fastening part 301, the strap or belt 4 is not connected to the base 300 in the region of the protruding edge forming the engagement part 341, but rather can be freely moved relative to the base 300 and in particular lifted from the base 300, so that the strap or belt 4 can be deformed during rotation of the connecting part 3 relative to the connecting part 2 to slide smoothly over the engagement projections 240, 241.
[0129] The exit line 306 is offset radially inwardly relative to an end edge 305 of the base 300 and is therefore radially spaced from said edge 305. The strap or belt 4 therefore emerges from the fastening portion 301 along a line that is set back relative to the edge 305.
[0130] The connecting part 3 can also be rotated much more from the position of Figures 12A to 12F. In principle, the connecting part 3 can be rotated to any desired angle relative to the connecting part 2.
[0131] Under a load between the straps or belts 4,5 the connecting parts 2,3 automatically return to the position of FIG.
[0132] Also, in principle, the attachment and detachment of the connecting part 3 to / from the connecting part 2 can be performed in any desired rotational position.
[0133] In the exemplary embodiment of Figures 1 to 12A-12F, the connecting device 1 provides a webbing fastener by which straps or belts can be connected to each other. The load direction determined by the straps or belts at the connecting position is oriented substantially along the engagement direction Y.
[0134] In another exemplary embodiment shown in Figures 13A and 13B to 20A-20D, the connecting device 1 is configured as an object fastening device and serves to fasten an object to a corresponding assembly, which object can for example be provided on or integrated into the (second) connecting part 3. This allows for example electrical and electronic devices such as communication devices, lights, etc. to be installed on a corresponding assembly, e.g., a helmet or other sports equipment item.
[0135] In the illustrated exemplary embodiment, as is clear from Figures 13A and 13B and Figures 14A to 14C, the (second) connecting portion 3 is formed rotationally symmetrically to form a base 300, which is cylindrically shaped and provided on a base body 30. A base surface 302 is formed on the underside of the base 300, and a blocking element 303 of circular cross section concentric with the base surface 302 protrudes from the base surface 302.
[0136] The storage section, which is raised relative to the base section 300, is formed with a fastening opening 35 for receiving the magnetic device 31.
[0137] The (second) connecting portion 3 in Figures 13A and 13B and 14A to 14C can be attached to the (first) connecting portion 2 shown in Figures 15A and 15B and 16A to 16C. The (first) connecting portion 2 has a base 20 on which a bottom surface 230 is formed, and the bottom surface 230 extends planarly and flatly on the connecting portion 3 side of the base 20 (when the connecting portions 2 and 3 are attached to each other), and when the connecting portions 2 and 3 are connected to each other, a base surface 302 of a base 300 of the connecting portion 3 comes into surface contact with the bottom surface 230.
[0138] As explained with reference to the previous exemplary embodiment, the bottom surface 230 is formed with a recess 231 for accommodating the blocking element 303 of the connecting part 3. Furthermore, the bottom surface 230 is bounded by an access opening 232 which is provided between the bottom surface 230 and a support 233 which is formed in the front region of the base body 20.
[0139] The undulating portions 242, 243 are provided with engagement protrusions 240, 241 that are firmly formed with the base body 20 and positioned above the bottom surface 230 when viewed along the vertical direction H. At the connecting positions of the connecting portions 2, 3, an engagement portion 341 formed by a radially protruding peripheral edge of the base portion 300 of the connecting portion 3 is received between the bottom surface 230 and the engagement protrusions 240, 241.
[0140] The base 20 defines at the rear of the bottom surface 230 a fastening opening 25 in which a magnetic device 21 is provided which magnetically interacts with the magnetic device 31 of the connecting part 3 .
[0141] The operations for connecting the connecting parts 2, 3, shown in Figures 17A and 18B to 20A-20D, proceed in the same manner as described above for the exemplary embodiment of Figures 1 to 12A-12F.
[0142] That is, as is clear from Figures 17A and 17B, the connecting parts 2, 3 are brought closer to each other along a closing direction X oriented along the vertical direction H. At this time, the magnetic devices 21, 31 interact magnetically to attract the connecting parts 2, 3 toward each other along the closing direction X, so that the connecting part 3 rides up onto the engagement protrusions 240, 241 and slides down at the rear ends 246, 247 of the engagement protrusions 240, 241, as is clear from Figures 18A and 18B. At this time, the base 300 comes into contact with the bottom surface 230 at the rear edge 304, and the connecting part 3 slides along the sliding direction A relative to the connecting part 2, so that the base 200 is moved over the engagement protrusions 240, 241 until it can pass the engagement protrusions 240, 241. This causes connecting part 3 to move relative to connecting part 2 into the position of Figures 19A and 19B, keeping the blocking portion above recess 231 and preventing premature interlocking of connecting parts 2,3.
[0143] As the base 300 passes the engagement protrusions 240, 241 along the closing direction X, as can be seen in the transition from Figures 19A and 19B to Figures 20A and 20B, the engagement portions 341 formed on the base 300 slide into engagement with the (rigid) engagement protrusions 240, 241 in the engagement direction Y. In the same process, the blocking element 303 slides into the recess 231 with the magnetic assistance due to the magnetic attraction of the magnetic devices 21, 31.
[0144] 20A to 20D, the base 300 is disposed in a planar manner on the bottom surface 230 of the connecting portion 2 at the base surface 302. The blocking element 303 is disposed in the recess 231. As is clear from FIG. 19B, the front edge 305 of the base 300 contacts the support portion 233 and is placed on the step 234 between the entrance opening 232 and the support portion 233. At this time, the engaging portion 341 formed on the base 300 engages with the engaging protrusions 240, 241, so that the connecting portion 3 is held by form-fitting or frictional engagement with the connecting portion 2, the positions of the connecting portions 2, 3 are fixed by the magnetic devices 21, 31, and the blocking element 303 prevents disengagement in the direction opposite to the engagement direction Y.
[0145] Due to the rotational symmetry of the connecting part 3, it can be rotated on the connecting part 2 in said connecting position.
[0146] Also, due to said rotational symmetry, the connecting part 3 can be arranged on the connecting part 2 in any desired rotational position, allowing simple and easy connection of the connecting parts 2, 3 to each other.
[0147] To separate the connection 2, 3, the connecting part 3 can be tilted relative to the connecting part 2 in a tilting plane spanning the closing direction X and the engagement direction Y, so that the engagement part 341 formed by the edge of the base part 300 enters the entry opening 232, as is also evident from Fig. 19B. This releases said blocking of the blocking element 303 in the recess 231, allowing the connecting parts 2, 3 to be detached from one another.
[0148] In further exemplary embodiments of the form of the webbing fastener shown in Figures 21 to 30A-30D, the first connecting part 2 has a base body 20 in which a receiving opening 23 is formed. The second connecting part 3 can be attached to the first connecting part 2 by inserting a pin element 340 formed on a base part 300 of the base body 30 of the second connecting part 3 into the receiving opening 23 and engaging with an arc-shaped engagement protrusion 240 on a wall part of the receiving opening 23 of the first connecting part 2 via a circumferential engagement part 341.
[0149] In the illustrated exemplary embodiment, the strap or belt 4 is fixedly connected to the base 30 of the connecting part 3 by a fastener 301 formed on the base 300. The base 300 has a cylindrical disk-like basic shape and forms a base surface 302 on the connecting part 2 side.
[0150] A mushroom-shaped pin element 340 carrying an engagement portion 341 protrudes from the base surface 302. The engagement portion 341 extends circumferentially around the closing direction X to realize the engagement device 34. That is, in the illustrated exemplary embodiment, the engagement portion 341 is spaced apart from the base 300 along the closing direction X, and thus is spatially separated from the base 300.
[0151] In the illustrated exemplary embodiment, the engagement portion 341 is formed with a slope 342 in the form of a conical surface. When the connecting part 3 is attached to the connecting part 2, the engagement portion 341 rides up on the engagement protrusion 240 in the receiving opening 23 at the slope 342, so that the connecting part 3 is biased relative to the connecting part 2 in the direction opposite to the engagement direction Y, and the engagement portion 341 moves past the engagement protrusion 240 until it can be brought into engagement with the engagement portion 240 in the engagement direction Y.
[0152] The connecting parts 2, 3 each include a magnetic device 21, 31 (see Figures 22A and 22B) that faces each other so as to be magnetically attracted along the closing direction X, thereby magnetically assisting the attachment of the connecting parts 2, 3 in the closing direction X.
[0153] In the illustrated exemplary embodiment, the disk-shaped base 300 protrudes radially beyond the engagement portion 341 of the pin element 340, as can be seen in Figures 25A, 25B, 26A and 26B.
[0154] When the connecting parts 2, 3 are attached to each other, the connecting part 3 is shown in the order of Figures 27A and 28B through 30A-30D, and first, as is clear from Figure 28B, the engaging part 341 comes into contact with the engaging protrusion 240 in the storage opening 23 by means of the inclined surface 342 formed on the engaging part 341, and then, as is clear from the transition from Figures 28A and 28B to Figures 29A and 29B, the engaging part 341 is moved toward the connecting part 2 in the closing direction X in a state in which it is able to perform a swinging motion in which it slides past the engaging protrusion 240.
[0155] As the engaging portion 340 passes the engaging projection 240, it comes into engagement with the engaging projection 240 in the engaging direction Y due to the magnetic attraction between the magnetic devices 21, 31, thereby moving the connecting portions 2, 3 to the connected position of Figures 30A to 30D.
[0156] In the coupled position, the engagement portion 341 of the pin element 340 engages with the arcuately curved engagement protrusion 240 on the wall of the receiving opening 23. At this time, on the opposite side of the engagement protrusion 240, the engagement portion 341 faces a blocking portion 238 in the form of a protruding element protruding in the engagement direction Y into the receiving opening 23. As a result, the blocking portion 238 blocks tangential movement of the pin element 340 in the receiving opening 23 in the direction opposite to the engagement direction Y, thereby preventing the engagement between the engagement portion 341 and the engagement protrusion 240 from moving.
[0157] 30B, in the connected position, the circumferential outer edge 305 of the base contacts the support part 233 attached to the upstream side of the engagement protrusion 240 in the engagement direction Y. As a result, the support part 233 supports the base 300 in the engagement direction Y, so that when a load is applied between the connecting parts 2, 3, the force along the load direction corresponding to the engagement direction Y is absorbed and guided away by the support part 233.
[0158] As is also clear from Fig. 30B, in the region of the support part 233, a form-engaging part 234 in the form of a step is formed on which the base part 300 rests at its edge 305 in the closing direction X. This step resists the tilting of the base part 300 relative to the connecting part 2, i.e., the tilting of the connecting part 3, so that the connecting parts 2 and 3 are not accidentally separated from each other under a load.
[0159] As is clear from Figure 30B together with Figure 29B, the step 234 is bordered by an entrance opening 232 that provides a gap into which the base 300 can enter when the connecting parts 2, 3 are tilted relative to one another, as is clear from Figure 29B.
[0160] When the connecting parts 2, 3 are to be separated from one another, the user can pull on an actuation part in the form of a tab 40 on the rear side of the connecting part 3, which can lift the pin element 340 out of the receiving opening 240 on the side opposite the engagement projection 240, as is clear from Fig. 29B. The base 300 enters the entry opening 232 in the front area on the support part 233 side, facilitating tilting of the connecting part 3 relative to the connecting part 2, thereby separating the connecting parts 2, 3 from one another.
[0161] 1 to 12A-12F, in the connected position, tilting when a load is applied is resisted by the support of the step 234. Here, the access opening 232 in the area adjacent to the step 234 in the direction opposite to the engagement direction Y is used to provide a gap into which the base 300 can enter at its peripheral edge when the connecting parts 2, 3 are tilted relative to each other to separate the connection.
[0162] In the exemplary embodiment shown in Figures 21 to 30A-30D, the engagement portion 341 is not formed on the disk-shaped base 300, but rather on a pin element 340 that projects from the base 300 in the closing direction X, such that the engagement portion 341 is spaced from the base 300 in the closing direction X and a peripheral edge 305 of the base 300 is located radially outward of the engagement portion 241.
[0163] That is, the engaging portion 341 is spatially separated from the base 300. Moreover, the generation of form-engagement or friction-engagement by the engaging portion 341 is functionally separated from the support of the base 300 by the support portion 233 and the form-engaging portion 234. As a result, for example, not only is load absorption performed by the support of the base 300 by the support portion 233, but the base 300 can provide a relatively large leverage for support purposes compared to the engaging portion 341, so that resistance to tilting can be performed by the form-engaging portion 234.
[0164] 21 to 30A-30D, the support portion 233 is firmly formed on the base 20 of the connecting portion 2 by a surface portion that extends perpendicular to the radial direction with respect to the closing direction X and is curved in an arc centered on the closing direction X, as is clear from Fig. 24A as well as Fig. 30B. The shape engagement portion 234 in the form of a step is also curved in an arc similarly, thereby providing support for the edge portion 305 of the base 300.
[0165] 31A to 31C, an arc-shaped support portion 233 extending obliquely in the closing direction X collectively performs the functions of the support portion 233 and the form-engaging portion 234 in the exemplary embodiment of Fig. 21 to 30A to 30D. The obliquely extending support portion 233 in the exemplary embodiment of Fig. 31A to 31C constitutes a support for the oblique edge portion 305 of the base portion 300 of the connecting portion 3, and is therefore used not only to provide support in the engagement direction Y, but also to provide support against tilting, i.e., against the movement of the base portion 300 in the front region in the closing direction X.
[0166] Other than that, the exemplary embodiment of FIGS. 31A to 31C is the same as the exemplary embodiment of FIGS. 21 to 30A to 30D, so please refer to the previous explanations.
