Description

The invention relates to a belt buckle according to the preamble of claim 1.

A belt buckle of this type has a connecting device which comprises a first connecting part which has a first base body and at least one engagement projection which is arranged rigidly on the first base body. The connecting device also includes a second connecting part, which can be attached to the first connecting part in a closing direction and is connected to a belt, which has a second base body with an engagement section rigidly arranged on the second base body, the engagement section running along a direction that is different from the closing direction, for example transversely or can be brought into engagement with the at least one engagement projection of the first connection part in the engagement direction directed obliquely to the closing direction, so that when the first connection part and the second connection part are in a connected position, the engagement section engages with the at least one engagement projection of the first connection part. The first connecting part has a first magnetic device and the second connecting part has a second magnetic device. The first magnetic means and the second magnetic means magnetically attractively cooperate to assist in attaching the first connector and the second connector to each other along the closing direction. In the connection device, one or more engagement projections are rigidly formed on the first main body of the first connection part. The second connection part can be brought into engagement with the at least one rigid engagement projection by bringing an engagement section of the second connection part into engagement with the at least one engagement projection of the first connection part. The first connecting part and the second connecting part are attached to each other along a closing direction, along which magnetic devices of the connecting parts provide a magnetic attraction force, so that the connecting parts are pulled toward one another along the closing direction. In contrast, the engagement portion of the second connection part is brought into engagement with the at least one engagement projection of the first connection part along an engagement direction which is directed transversely to the closing direction. In the connected position, the engagement section is in positive or non-positive engagement with the at least one engagement projection, so that the connecting parts are held together.

In the present case, the fact that the direction of engagement differs from the direction of closure is to be understood to mean that the direction of engagement is directed perpendicularly or at an oblique angle to the direction of closure. The direction of engagement is not necessarily directed exactly perpendicularly to the closing direction, but can extend at an oblique angle to the closing direction. However, the direction of engagement is not directed along the closing direction, in particular not in the opposite direction to the closing direction.

In a locking device known from EP 3 616 553 A1 for detachably connecting two parts, a first connecting part can be attached to a second connecting part in order to connect the connecting parts to one another. A shoelace is arranged on one of the connecting parts, which can be tightened by connecting the connecting parts to one another.

A closure device is known from EP 3 192 388 B1, 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.

In a connection device of the type mentioned, it is generally desirable to enable the connection parts to be connected in a simple, comfortable and haptically pleasant manner for a user. The connection should preferably be made possible in a position-tolerant manner, with imprecise attachment of the connecting parts to one another. In When the connecting parts are in a connected position, a secure, resilient connection should be created.

The object of the present invention is to provide a connecting device in which the connecting parts can be attached to one another in a simple, convenient manner and provide a secure, resilient hold on one another in a connected position.

This object is solved by an object with the features of claim 1.

Accordingly, in the connected position, the second connecting part can be rotated about the closing direction in relation to the first connecting part, with the engagement of the engagement section with the at least one engagement projection remaining in place when rotated. In the connected position, the engagement section is arranged on a first side of the at least one engagement projection, viewed in the closing direction, and the belt can be brought into a position relative to the at least one engagement projection or by twisting the second connecting part relative to the first connecting part, in which the strap extends beyond the at least one engagement projection on a second side opposite the first side.

To connect the connecting parts to one another, the connecting parts are attached to one another in such a way that the engagement section engages with the at least one engagement projection on the base body of the first connecting part, so that an engagement is produced between the connecting parts and the connecting parts are thus connected to one another. In the connected position, the second connection part can be rotated about the closing direction relative to the first connection part. On the one hand, this can allow the connecting parts to be attached to one another with tolerance for angles. In addition, this makes it possible to rotate the second connection part relative to the first connection part when the connection parts are in the connected position. In the event of twisting, the engagement section and the at least one engagement projection retain their engagement. A rotation of the connecting parts about the closing direction relative to one another in the connected position therefore does not lead to the connecting parts being separated from one another.

The pivotability between the connecting parts in the connected position can allow any rotational movement through any angle. But it is also conceivable that the movement of the connecting parts, for example, by stops or The like is limited to a predetermined angle of rotation. The angle of rotation is preferably greater than 10°, more preferably greater than 20°, particularly preferably greater than 45° or even greater than 90°.

Because the at least one engagement projection is formed rigidly and undeformably (when a load is acting as intended) on the first base body of the first connecting part, the engagement projection can reliably absorb and dissipate forces when it engages with the engagement section of the second base body. The at least one engagement projection is preferably formed in one piece with the first base body of the first connecting part, with the first base body being designed to be rigid and non-deformable overall.

In this context, “non-deformable” should be understood to mean a substantially rigid geometry and choice of material for the base body, which means that the base body of the first connecting part with the engagement projection formed on it does not deform under a specified load, i.e. the base body is not designed to be elastic. For example, the main body of the first connection part can be made of metal or a hard plastic material.

Likewise, the main body of the second connecting part with the engagement portion formed thereon is rigid and non-deformable and is made of metal or a hard plastic material, for example.

The attachment of the connecting parts to each other is supported magnetically. For this purpose, the first connecting part has a first magnetic device and the second connecting part has a second magnetic device. In the connected position, the first magnetic device and the second magnetic device interact in a magnetically attractive manner and in particular also support the attachment of the connecting parts to one another. The magnetic devices have a magnetically attractive effect along the closing direction, so that the magnetic devices cause a magnetic attraction force along the closing direction and pull the connecting parts towards one another along the closing direction when they are attached. The magnet devices can each be formed by a permanent magnet, for example. However, it is also possible to design one of the magnet devices with a permanent magnet and the other of the magnet devices with a magnetic armature and thus with a passive-magnetic element. Due to the rotational mobility about the closing direction, a position-tolerant attachment of the connecting parts to one another is possible, in that it is not necessary to attach the connecting parts to one another in an exactly defined rotational position. The connecting parts can thus be attached to one another in a certain angular range or preferably in any rotational position, with the connecting parts preferably aligning themselves to one another under load.

In order to enable rotational mobility in the connected position and position-tolerant attachment to one another, the belt on the second connecting part can be brought into a position in the connected position in relation to the at least one engagement projection or is in a position in which the belt is on one of the engagement sections remote (second) side over the at least one engagement projection is extended away. The belt arranged on the second connection part (fixed or adjustable) can thus be moved over the at least one engagement projection on the first connection part - with or without touching the engagement projection - when the connection parts are in the connected position and are rotated relative to one another. The belt can thus, for example, slide onto the at least one engagement projection and be moved over the engagement projection on the side facing away from the floor surface, so that the engagement of the engagement projection of the first connection part with the engagement section of the second connection part does not impede the mobility of the connection parts relative to one another.

Provision can be made for the belt to always extend beyond the at least one engagement projection, regardless of the rotational position of the connecting parts relative to one another, so that the belt is arranged in relation to the at least one engagement projection in any rotational position of the connecting parts relative to one another such that the at least one engagement projection is below the Belt (with respect to the closing direction) is arranged. The belt is thus (always) in a position in which it extends beyond the at least one engagement projection on the second side facing away from the first side.

However, it can also be provided that the belt does not extend beyond the at least one engagement projection in one rotational position, but extends beyond the at least one engagement projection in another rotational position. The belt can thus be moved relative to the at least one engagement projection and thus extends over the engagement projection or not, depending on the rotational position.

When it is said here that the strap should extend beyond the at least one engagement projection, this means that the strap extends approximately radially away from the second connecting part in the intended manner, starting from the second connecting part, and the section starting from the second connecting part of the strap extends beyond the at least one engagement projection.

Moving over the engagement projection can be done with flexible deformation of the strap. However, it is also conceivable for the belt to be arranged at such a height on the second connecting part that the belt can be moved over the at least one engagement projection without being deformed.

In one embodiment, the second connecting part has a fastening section to which the belt is fastened. In this case, the belt extends freely from an exit point to the fastening section. The strap is fixed to the second connecting part via the fastening section, which can be formed in one piece on the second base body, for example by plastic injection molding. At the point of exit, the strap emerges from the fastening section and extends freely beyond the point of exit, ie outside of the fastening section, to the fastening section.

The exit location corresponds to the location where the strap exits the attachment portion. The belt is fixed to the fastening section. On the other hand, beyond the exit point, ie outside of the fastening section, the belt is free and can be moved towards the fastening section. In this case, the exit point can, for example, extend linearly at the transition between the fastening section and the outer area, corresponding to the width of the belt. In the case of a linear exit point, the exit point can extend in a straight line or in a curved manner.

In this case, the belt is preferably not connected to the base body beyond the point of exit, in particular not to the engagement section, which protrudes radially to the fastening section, for example. The belt can thus be moved freely toward the base body radially outside of the fastening section. This allows the webbing to slide over the engagement portion with the at least one engagement projection to move away the engagement projection without thereby impeding the engagement of the engagement portion with the at least one engagement projection.

In one embodiment, the exit point is spaced radially from an axis of rotation directed along the closing direction, about which axis of rotation the second connecting part can be rotated relative to the first connecting part in the connected position.

The exit point can be arranged radially to the axis of rotation between the axis of rotation and the engagement section. In this case, the exit point, in the case of a linear (straight or curved) extension, can be arranged completely or only partially radially inside the engagement section.

Alternatively, the exit point is arranged radially outside of the engagement section and is therefore radially at a greater distance from the axis of rotation than the engagement section. In this case, the exit point, in the case of a linear (straight line or curved) extension, can be arranged completely or only partially radially outside the engagement section.

The spacing from the axis of rotation can in particular ensure that loading forces introduced into the second connecting part via the belt do not lead to an (unintended) tilting of the second connecting part relative to the first connecting part and thus the connecting parts are safe and reliable in the connected position even under load are held together.

In one embodiment, the strap is arranged on a first side of the fastening section and extends from the fastening section on this first side. A further belt section can be arranged on a second side of the fastening section which faces away from the first side of the fastening section. The first side of the fastening section and the second side of the fastening section face away from one another, in particular diametrically with respect to the axis of rotation. The further belt section can be formed by the belt, which thus extends through the fastening section. However, the further base section can also be formed by another belt which is fastened to the fastening section.

While loading forces can be introduced into the second connecting part via the strap and the strap extends when loaded, starting from the fastening section in the direction of the at least one engagement projection, For example, an actuation section can be made available via the further belt section, on which a user can grip in order to detach the connecting parts from one another. Alternatively, however, a connection to a superordinate assembly can also be established via the additional strap section, so that loading forces can also be introduced into the second connecting part via the additional strap section.

In an operational state, for example, a further belt is arranged on the first connecting part, so that belt forces can act between the belts on the first connecting part and on the second connecting part. Alternatively, the first connection part is arranged on a superordinate assembly, for example a piece of clothing, a bag, a belt or the like. A load direction is directed approximately along the engagement direction, for example, so that when there is a load between the connecting parts, the engagement section is pulled into engagement with the at least one engagement projection.

In the connection device, the load direction, along which a load force acts on the second connection part when the load is applied as intended in a loaded state, can preferably be directed with at least one directional vector component in the direction of engagement. The load direction is thus at least approximately in the direction of engagement or at an angle to the direction of engagement, so that the load direction at least also points in the direction of engagement, namely in a vector decomposition with a directional vector component. In the loaded state, the second connection part is thus (at least also) loaded in the engagement direction relative to the first connection part and thus in the direction of engagement with the at least one engagement projection rigidly formed on the first connection part.

In one embodiment, the first connecting part has a blocking section which is rigidly arranged on the first base body and is designed to interact with the second connecting part in the connected position in order to block the engagement of the engagement section with the at least one engagement projection counter to the engagement direction. In the event of twisting, the engagement of the engagement section with the at least one engagement projection and the blocking of the engagement by the blocking section remain. In the connected position, the second connecting part can be tilted relative to the first connecting part in order to unblock the first connecting part and the second connecting part from one another in the opposite direction to the engagement direction and disengage the to allow at least one engagement portion and the at least one engagement projection.

The connecting parts are to be attached to one another along the closing direction, the attachment of the connecting parts to one another being magnetically assisted by the magnetic devices of the connecting parts. When they are attached, the connecting parts are magnetically drawn towards one another by the magnetic device and are also magnetically held together in the connected position.

When the connection parts are attached, the engagement section of the second connection part comes into engagement with the at least one engagement projection of the first connection part in the engagement direction pointing, for example, perpendicularly or at an angle to the closing direction, so that in the connected position there is a positive or non-positive connection between the connection parts and the connection parts as a result are held together in a resilient manner by the engagement of the engagement section with the at least one engagement projection. The engagement between the engagement section of the second connection part and the at least one engagement projection of the first connection part is secured in the connected position by the blocking section of the first connection part, which is rigidly formed on the first base body of the first connection part, in that the blocking section blocks against the direction of engagement with an associated section of the second connecting part and the engagement section thus cannot be moved counter to the engagement direction towards the at least one engagement projection, at least not without removing the blockage. Due to the blocking effect of the blocking section, the engagement section is thus locked in its engagement with the at least one engagement projection, so that the connecting parts are secured in the connected position relative to one another.

Due to the magnetic effect of the magnetic devices, the connecting parts are held in relation to one another in the connected position in such a way that the connecting parts are blocked by the blocking section of the first connecting part against the direction of engagement. The connecting parts can therefore not be detached from one another by a (pure) displacement movement counter to the direction of engagement.

Rather, is required to release the connecting parts from each other that the connecting parts are tilted to each other to the second connecting part so in a to move through the closing direction and the direction of engagement spanned tilting plane to the first connecting part, that the second connecting part can be moved counter to the direction of engagement to the blocking section. The blocking effect of the blocking section can be canceled by tilting the second connection part relative to the first connection part, so that the second connection part can be moved past the blocking section and the engagement section of the second connection part can thus be disengaged from the at least one engagement projection of the first connection part.

The blocking effect of the blocking section rigidly formed on the first base body of the first connecting part means that the second connecting part cannot be moved linearly counter to the direction of engagement, but can be tilted in a tilting plane spanned by the closing direction and the direction of engagement to separate the connecting parts from one another. The tilting movement can take place around a defined tilting axis. However, the tilting movement can also take place along a curved movement path located in the tilting plane, the second connecting part being tilted relative to the first connecting part as a result of the tilting movement. The tilting movement can be superimposed by a linear movement counter to the engagement direction and/or counter to the closing direction.

It should be noted that the connecting parts can be tilted relative to one another in order to separate the connecting parts. However, the connection between the connecting parts is also not produced in a straight-line closing movement, but by the connecting parts being attached to one another in a tumbling manner with tilting relative to one another and being moved into engagement with one another. When the connection is established, the second connection part can also be tilted relative to the first connection part in order to enable the engagement section of the second connection part to engage with the at least one engagement projection of the first connection part.

In one embodiment, the second connecting part can be lifted off the first connecting part counter to the closing direction for tilting relative to the first connecting part on a side facing away from the at least one engagement projection. In the connected position, the second connection part is in engagement with the at least one engagement projection on the first main body of the first connection part via the engagement section formed rigidly on the second base body, with this engagement taking place in a region of the second connection part that is at the front in relation to the direction of engagement. With a rear with respect to the engagement direction In the connected position, the second connecting part can be lifted off the first connecting part in the opposite direction to the closing direction, in order to tilt the second connecting part relative to the first connecting part and thereby cancel the blocking effect of the blocking section of the first connecting part, so that the second connecting part can move to the The blocking section of the first connecting part is moved and the engagement section can be disengaged from the at least one engagement projection counter to the engagement direction.

In order to make handling easier for a user, the second connection part can have an actuating section, for example, which a user can grip to tilt the second connection part relative to the first connection part. The actuating section can be formed, for example, by a tab in the rear area of the second connecting part, which a user can pull to lift the second connecting part with the rear area from the first connecting part counter to the closing direction. However, the actuating section can also be formed, for example, by a recessed grip or another gripping section on which a user can grip in order in this way to tilt the second connection part relative to the first connection part.

In one embodiment, the second connecting part has a blocking element, which is arranged rigidly on the second base body, for interacting with the blocking section of the first connecting part. For example, the blocking member may be formed on a base portion of the second connecting part forming the engaging portion and may protrude from the base portion along the closing direction. In the connected position, the blocking element interacts with the blocking section of the first connecting part, so that movement of the connecting parts counter to the engagement direction with respect to one another is blocked. However, by tilting the connecting parts relative to one another, the blocking element can be lifted above the blocking section, in order in this way to cancel the blocking and move the connecting parts toward one another while tilting counter to the engagement direction, so that the engagement between the engagement section of the second connection part and the at least one engagement projection of the first Connection part lifted and the connection parts can be separated from each other.

For example, the blocking element can be cylindrical in shape and, viewed in a cross-sectional plane perpendicular to the closing direction, have a circular shape. In the connected position, the blocking element can be rotated about the closing direction to the blocking section, so that the connecting parts can be rotated relative to one another.

In one configuration, the first base body has a recess which is delimited at least in sections by the blocking section. In the connected position, the blocking element lies in the recess, so that the engagement of the engagement section with the at least one engagement projection is blocked counter to the engagement direction. The recess can be formed, for example, as a depression on a bottom surface of the first base body of the first connecting part. The recess is thus formed in the bottom surface. The blocking element is brought into engagement with the recess when the connection parts are placed on one another, so that the second connection part is held on the at least one engagement projection of the first connection part by the engagement.

In one embodiment, the recess is delimited (in a cross-sectional plane perpendicular to the closing direction) by at least one delimiting wall which forms the blocking section and extends along an arc of a circle. The recess can have a circular basic shape, for example, in which the at least one boundary wall extends in an arc along an (imaginary) circle centered on an axis.

For example, the recess is delimited by two arcuate boundary walls, which together form the blocking section and, in the connected position, receive the blocking element of the second connecting part between them and thus block a movement counter to the engagement direction of the second connecting part relative to the first connecting part. The one or more boundary walls are arranged, for example, at right angles to the floor surface and thus provide support surfaces for the blocking element, so that when a load is applied, the blocking element is supported on the boundary walls and is thus blocked relative to the first connecting part.

In one embodiment, the blocking section has a ramp. The ramp is designed to provide a sliding guide for the blocking element counter to the direction of engagement when the second connecting part tilts relative to the first connecting part. When tilting the connecting parts relative to each other For example, a blocking element of the second connecting part can come into contact with the ramp, so that the blocking element can run onto the ramp and can thus be moved over the blocking section. Such a ramp can thus make it easier to separate the connecting parts from one another.

In one configuration, the at least one engagement projection is curved in an arc around the closing direction. If a (single) engagement projection is provided, it thus extends in an arc around the closing direction. If a plurality of 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 lined up along a circumferential direction pointing around the closing direction, so that the engagement projections are lined up along an arcuate line and jointly engage with the engagement portion of the second connecting part when the connecting parts are in the connected position.

The at least one engagement projection extends around the closing direction by an angle less than 180°, preferably less than 150°, to enable the engagement portion to be engaged with the at least one engagement projection in the engagement direction.

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.

The undercut can be formed here by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.

Likewise, the engagement portion of the second connection part preferably forms an undercut with respect to the closing direction. The engagement section is thus undercut with respect to the closing direction, in that the engagement section projects transversely to the closing direction from an associated section of the second connecting part. The undercut can in turn be formed by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.

In one embodiment, the engagement section extends circumferentially around the closing direction. In this case, the engagement section can be arranged, for example, on a pin element and can protrude from the pin element transversely to the closing direction.

For example, the engagement section is rotationally symmetrical with respect to the closing direction. This makes it possible to bring the engagement section into engagement with the at least one engagement projection on the first connection part in any rotational position of the second connection part relative to the first connection part, so that there is an engagement between the engagement section and the at least one engagement projection in any rotational position of the second connection part relative to the first connection part and the connecting parts can thus be twisted relative to one another without the engagement of the engagement portion with the at least one engagement projection being canceled.

In one configuration, the second base body of the second connecting part has a base section.

In one configuration, the base section can form the engagement section, so that the engagement section is shaped for engagement with the at least one engagement projection of the first connecting part on the base section, for example on a peripheral edge section of the base section.

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 in that the base section extends along a first plane and the engagement section extends along a second plane spaced apart from the first plane along the closing direction.

For example, when the engaging portion is spaced apart from the base portion, the engaging portion is formed on a pin member protruding from the base portion along the closing direction. The engagement section protrudes along the engagement direction from the pin section and thus forms an undercut, so that the engagement section with the at least one Engagement projection of the first connecting part can be engaged to produce a positive or non-positive connection.

For example, the engaging portion may be formed circumferentially on the trunnion member. In this way, a mushroom-shaped engagement element can be provided which can be brought into engagement with the at least one engagement projection of the first connecting part in any rotational position in order to connect the connecting parts to one another and to hold them together in the connected position.

If the engagement section is spatially spaced from the base section, the base section can extend further radially to the closing direction than the engagement section and thus project radially beyond the engagement section. The engagement portion is thus in a radially inner position, while an outer edge of the base portion is located radially outside of the engagement portion. In this way, a favorable support of the second connecting part on the first connecting part can be created via the base section when the connecting parts are in their connected position.

In one embodiment, the base section is shaped like a disk, for example. In this case, the base section can have, for example, a circular-cylindrical basic shape with a circular cross-section.

A fastening section can be formed on the base section, for example, via which a belt is connected to the second connecting part.

In one configuration, the base section of the second main body of the second connecting part has an edge section. The first connecting part, on the other hand, has a support section rigidly formed on the first base body, wherein in the connected position the edge section is supported with the support section for load bearing along the engagement direction. The edge section can be formed, for example, in a front area of the base section, in which case--if the base section is configured as circular-cylindrical--the edge section can also run around the circumference of the base section. The support portion is formed in a front portion of the first connecting part with respect to the engaging direction, so that the support portion can provide support for the base portion in the engaging direction. When loading the second connection part relative to the first connection part in the engagement direction, the edge portion is thus against the Pressed support portion and thus supported on the support portion. In the connected position, the base section can thus come into contact with the support section on the first base body of the first connection part via the edge section, so that loading forces can be introduced from the second connection part into the first connection part.

It is conceivable here 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 engagement direction, but only comes into contact with the support section when the connecting parts are loaded relative to one another.

Forces can advantageously be introduced from the second connection part into the first connection part via the support section and the support of the edge section of the base section on the support section. For example, if the connecting device is designed as a belt buckle, the load direction, along which a force acts between the connecting parts when the connecting device is used as intended, can (approximately) be directed along the engagement direction, so that when the load is applied, the engagement section is loaded in the direction of engagement with the at least one engagement projection . The edge section of the base section comes into supporting contact with the support section, so that forces acting in the direction of engagement are dissipated via the contact of the edge section with the support section. The at least one engagement projection is used here in particular for support along the closing direction and thus for securing the hold of the connecting parts on one another, with loading forces in the engagement direction being primarily absorbed and dissipated via the support section.

In one embodiment, the support section and the edge section are each curved in an arc shape in a cross-sectional plane perpendicular to the closing direction. In the case of a circular-cylindrical configuration of the base section, the edge section of the base section runs in a circle 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 supporting abutment with the support section of the first connection part. In one configuration, the support section is spaced apart from the at least one engagement projection, viewed along the closing direction. Viewed along the closing direction, the support section can extend above or below the at least one engagement projection.

Additionally or alternatively, the support section can be spaced apart from the at least one engagement projection, viewed along the engagement direction. The support section is therefore located at a different location than the at least one engagement projection with respect to the engagement direction. In particular, the support section can be positioned in front of the at least one engagement projection in the engagement direction, so that the support section is arranged radially outside of the at least one engagement projection. In this way, favorable support can be created via the support section, in that the base section can come into contact with the support section with a favorable lever arm when loading forces act between the connecting parts.

In one configuration, the support section is formed by a surface section which is directed parallel or at an angle to the closing direction. In this case, the support section is formed rigidly on the first base body of the first connecting part. Under load, the support section on the first connection part comes into contact with the base section of the second connection part, so that load forces acting in the direction of engagement can be absorbed and dissipated in a favorable manner.

In one embodiment, the first connecting part has two engagement projections, which are spaced apart from one another along a transverse direction pointing perpendicularly to the engagement direction and perpendicularly to the closing direction. At least one section of the support section is arranged here, viewed along the transverse direction, between the engagement projections and also along the engagement direction at a distance from the engagement projections. Due to the fact that the engagement projections are spaced apart from one another along the transverse direction extending transversely to the engagement direction and are preferably arranged at the same axial position, viewed along the engagement direction, a load from the engagement section acts on the engagement projections with a directional vector component (also) in the direction of a Spreading of the engagement projections along the transverse direction to one another, which could possibly be disadvantageous for the stability of the connection. For this reason, a support section is additionally provided, which has at least a section (viewed along the transverse direction) between the engagement projections and also along the engaging direction is spaced apart from the engaging projections. At least a portion of the support portion is thus arranged between the engagement projections and in front of the engagement projections in the engagement direction, so that the support portion can support an edge portion of the engagement portion of the second connecting part and thus can absorb a load when loaded in the engagement direction.

Because the support section thus has a supporting effect in the engagement direction, an excessive load is avoided, in particular in the direction of a spreading at the engagement projections when the connection device is under load. The stability of the connection can thus be improved.

In one configuration, 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 perpendicularly to the closing direction. In the connected position, the base surface on the base portion of the second connection part and the bottom surface on the first body of the first connection part face each other.

For example, in the connected position, there may be abutment between the base surface and the bottom surface. When the connecting parts are twisted about the closing direction relative to one another, the base surface and the bottom surface are thus moved in a sliding manner on one another.

However, this is not mandatory. It is also conceivable that in the connected position there is a distance (and therefore no contact) between the base surface and the bottom surface.

In one embodiment, the base section can be tilted relative to the first connecting part about a tilting axis perpendicular to the closing direction and to the engagement direction, in order to tilt the connecting parts relative to one another. The tilting of the connecting parts for separating the connecting parts from one another thus takes place in that the base section is tilted about a tilting axis relative to the first main body of the first connecting part. In this case, the tilting axis can be defined by a contact line between the base section and the first base body. However, it is also conceivable that the tilting axis corresponds to an imaginary line that extends through the base section or outside of the base section and one corresponds to such a line about which the base section is pivoted relative to one another when the connecting parts are tilted.

In one configuration, the first base body has an insertion opening into which a section of the base section can insert when the second connecting part is tilted relative to the first connecting part in the closing direction. The immersion opening can be formed in particular in a front region (with respect to the engagement direction) of the first base body and can be formed, for example, as a depression on the first base body. In particular, a front edge section of the base section can dip into the immersion opening when the connecting parts (when connecting or separating) are tilted relative to one another.

The immersion opening can be shaped, for example, as a depression relative to the bottom surface of the first base body. In this case, the immersion opening adjoins the bottom surface, for example, but is recessed in relation to the bottom surface and is thus set back along the closing direction. The immersion 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 enter with the edge section when the connecting parts are attached to one another to close the connecting device and even if the connecting parts are separated from each other to open the connecting device.

If the engagement section is formed spatially separately 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 an edge of the base section to dip into.

In general, a tilting of the connecting parts relative to one another for establishing the connection and also for separating can be facilitated by a play between the engagement section of the second connection part and the at least one engagement projection of the first connection part. Alternatively, a space for providing play can be created, for example, by a bevel on the engagement section, which allows the engagement section to tilt relative to the at least one engagement projection. In particular, when the engaging portion is formed on a peripheral edge portion of the base portion, the immersion opening is formed, for example, as a recess relative to a bottom surface of the first connecting part and connects to the bottom surface in a region facing the support portion. The immersion opening can be extended between the support section and the bottom surface, for example.

If the engagement section is formed on a pin below the base section and the base section protrudes radially beyond the engagement section, the immersion opening is preferably formed radially outside of the at least one engagement projection on the first base body.

The immersion opening can be designed as a depression or as a through-opening on the first base body.

In one embodiment, the first base body has a form-fitting section against which the base section rests in the connected position of the first connecting part and the second connecting part to counteract tilting of the second connecting part relative to the first connecting part. The form-fitting section is formed in particular in a region of the first base body that is at the front with respect to the direction of engagement and is rigidly configured on the first base body. The base section is supported on the form-fitting section, in particular in the closing direction, so that tilting of the second connecting part relative to the first connecting part is at least made more difficult by the support on the form-fitting section.

When tilting to separate the connecting parts from one another, the second base body is brought out of interaction with the form-fitting section on the first base body by a slight movement counter to the direction of engagement within the scope of play. There can be play between the second connecting part and the blocking section of the first connecting part, which allows a (slight) displacement movement of the second connecting part counter to the direction of engagement, or play between the second connecting part and the at least one engaging projection, which allows a (slight) tilting movement and a subsequent displacement movement of the second connecting part counter to the direction of engagement can be provided. Due to the movement within the framework of the game, the second base body is disengaged from the form-fitting section, for example by the second base body moving away from the, for example, in the manner of a step molded form-fitting section slips. The connecting parts can then be tilted (more) relative to one another, so that the connecting parts can be separated from one another.

The form-fitting section can be formed, for example, by a step on which the base section rests in the connected position. In this case, the form-fitting section can in particular have a surface section which is oriented perpendicularly or at an angle to the closing direction and provides support for the base section.

In another configuration, the positive-locking section can also be formed as an access opening, for example in the form of a notch, on the support section. The form-fitting section provides support on the base section perpendicular to the direction of engagement, namely along the closing direction, so that the connecting parts in the connected position cannot easily tilt unintentionally to one another under load, but are supported via the form-fitting section against (unintentional) tilting.

In one configuration, the form-fitting section is spaced apart from the at least one engagement projection, viewed along the closing direction. In this case, the form-fitting section can extend above or below the at least one engagement projection, viewed along the closing direction.

Additionally or alternatively, the form-fitting section, viewed along the direction of engagement, can be spaced apart from the at least one engagement projection. The form-fitting section is therefore located at a different location than the at least one engagement projection with respect to the engagement direction. In particular, the form-fitting section can be positioned in front of the at least one engagement projection in the engagement direction, so that the form-fitting section is arranged radially outside of the at least one engagement projection. In this way, favorable support can be created via the form-fitting section against tilting of the connecting parts relative to one another, in that the base section can come into contact with the form-fitting section with a favorable lever arm when loading forces act between the connecting parts.

In one embodiment, the at least one engagement projection has a sliding slope, for example, which serves as a guide slope to guide the connecting parts when they are attached to one another in such a way that the connecting parts can be brought into engagement with one another easily, preferably largely automatically. The sliding bevel is preferably designed to guide the second connecting part when it is placed on the first connecting part along the closing direction on the at least one engagement projection in such a way that the second connecting part is offset against the engagement direction with respect to the first connecting part and thereby moves past the at least one engagement projection becomes. After moving past, the second connection part can then be brought into engagement in the engagement direction with the at least one engagement projection of the first connection part. By sliding on the at least one engagement projection, the second connection part is thus guided relative to the first connection part that the second connection part is moved past the at least one engagement projection. If the second connection part has passed the at least one engagement projection with its engagement section, the engagement section can be brought into engagement in the engagement direction with the at least one engagement projection on the first connection part.

In one embodiment, the belt is fixed and not adjustable, but optionally also adjustable on the second connection part.

The first connection part can also be connected to a belt, but can also be arranged on an associated assembly, for example a textile object or another object.

In one embodiment, the first connecting part has two engagement projections which are spaced apart from one another transversely to the closing direction and transversely to the engagement direction such that the belt can be passed between the engagement projections when the first connecting part and the second connecting part are in the connected position. The belt is thus accommodated between the engagement projections, so that the engagement projections on both sides of the belt support the second connection part relative to the first connection part.

In an exemplary embodiment illustrated in FIGS. 1 to 12A-12F, 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.

The connecting parts 2, 3 can generally be attached to one another along a closing direction X, with the connecting parts 2, 3 each having a magnet device 21, 31 in the form of a permanent magnet (or alternatively in the form of a permanent magnet on the one hand and in the form of a magnetic armature on the other) which magnetically attractive interaction and pull the connecting parts 2, 3 towards each other along the closing direction X.

It should be noted that the attachment of the connecting parts 2, 3 can also be possible in a direction deviating from the closing direction X, for example directed obliquely to the closing direction X. The magnetic devices 21, 31 act along the Closing direction X magnetically attractive together and pull the connecting parts 2, 3 along the closing direction X towards each other.

As can be seen from the exploded views according to FIGS. 2A and 2B and the separate views according to FIGS. A webbing receptacle 22 in the form of a web and an adjoining opening, to which a webbing 5 can be attached or is attached, is arranged on the base body 20 . On a side facing away from the receiving opening 23 , the base body 20 forms a fastening opening 25 for receiving the magnetic device 21 .

The receiving opening 23 is formed as a depression on the base body 20 . Inside the receiving opening 23 there is a bottom surface 230 in the form of a flat surface extending perpendicularly to the closing direction X, with which the second connecting part 3 can be brought into planar contact when inserted into the receiving opening 23 to establish a connection of the connecting parts 2, 3.

A recess 231 in the form of a depression is formed in the bottom surface 230, in which--as will be described below--a blocking element 303 on a base section 300 of the second connecting part 3 engages when the connecting parts 2, 3 are in the connected position.

The receiving opening 23 is limited at a front end by a support section 233, which serves as a support and load bearing for the second connecting part 3 in the connected position. A plunge opening 232 is formed between the support portion 233 and the bottom surface 230, which serves to facilitate the making of the connection as well as the separating of the connecting parts 2, 3 by an edge portion 305 of the base portion 300 of the second connecting part 3 when making the connection and can also dip into the immersion opening 232 when the connection is separated, as can be seen, for example, in FIG. 10B and is to be described below.

The immersion opening 232 is formed as a depression relative to the bottom surface 230 and connects to the bottom surface 230 in such a way that the immersion opening 232 is located between the support section 233 and the bottom surface 230 . At the transition between the dip opening 232 and the bottom surface 230 is a beveled transition surface 237, which serves as a guide for the second connecting part 3 for connecting as well as for disconnecting.

Arranged on the rigid base body 20 on two lateral, raised sections 242, 243 are engagement projections 240, 241 which are rigidly formed with the base body 20 and which—when viewed along a height direction H pointing along the closing direction X—are located above the bottom surface 230 and are used for this purpose , to produce a positive or non-positive connection between the connecting parts 2, 3 in the connected position. The engagement projections 240, 241 are spaced from each other along a transverse direction Q . The engagement projections 240, 241 together form an engagement device 24 which enables a positive or non-positive 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 the connected position with an engagement section 341 formed thereon 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 about the connecting parts 2, 3 are held together securely and reliably.

Sliding bevels 244, 245 are formed on the engagement projections 240, 241, which are inclined obliquely to the height direction H and cause the second connecting part 3 to slide off against an engagement direction Y when the connecting parts 2, 3 are attached to one another along the closing direction X.

The recess 231 is delimited laterally by arcuate boundary walls 236 which together form a blocking section of the first connecting part 2 and are aligned perpendicularly to a bottom of the recess 231 and also to the bottom surface 230 . The boundary walls 236 extend in the shape of a circular arc around a central axis B of the recess 231 , which is directed along a normal direction N of the bottom surface 230 .

A ramp 235 is formed between the boundary walls 236, which is arranged at the rear of the support section 233 on the recess 231 and provides a sliding surface to facilitate the sliding of the blocking element 303 into the recess 231 and also the release of the blocking element 303 from the recess 231. The bottom surface 230 extends flat along a plane perpendicular to the normal direction N.

As can be seen from the exploded views according to FIGS. 2A, 2B and the separate views according to FIGS. 5A, 5B and 6A-6C, the second connecting part 3 is firmly connected to a belt 4. The second connecting part 3 has a base body 30 on which the belt 4 is arranged in a fixed and non-adjustable manner in that the belt 4 rests in a belt-webbing receptacle 32 formed between a base section 300 and a fastening section 301 and is thus arranged firmly on the base body 30.

The base body 30 can, for example, be formed in one piece and integrally with the base section 300 and the attachment section 301 by plastic injection molding, with the belt 4 being overmolded in sections and thus being firmly and non-adjustably connected to the base body 30 .

The base section 300 has a circular-cylindrical basic shape and forms a base surface 302 on a side facing the first connection part 2 (when the connection is established), which is flat and, when the second connection part 3 is attached to the first connection part 2, is flat with the bottom surface 230 in the receiving opening 23 comes into contact.

A blocking element 303 , which is circular in cross section and is concentric to the circular-cylindrical base section 300 , protrudes from the base surface 302 and serves to engage in the recess 231 on the bottom surface 230 of the base body 20 of the first connecting part 2 .

A fastening opening 35 is formed within the blocking element 303, which is used to receive the magnet device 31, for example in the form of a permanent magnet, of the second connecting part 3 and within which the magnet device 31 is fastened.

The base section 300 forms an engagement device 34 of the second connection 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 connection part 2 and, when the connection is established, dips under the engagement projections 240, 241, so that a form-fitting or a non-positive connection between the connecting parts 2, 3 is produced. In the exemplary embodiment shown, the engagement section 341 is formed by a peripheral edge of the base section 300, which projects radially in relation to the fastening section 301 and thus forms an undercut, via which the engagement section 341 engages with the engagement projections 240, 241 of the first connecting part 2, which also form undercuts can be brought to connect the connecting parts 2, 3 together.

A connecting process of the connecting device 1 is shown with reference to FIGS. 7A, 7B to 11A-11D.

The attachment of the connecting parts 2, 3 to each other generally takes place along the closing direction X, along which the magnetic devices 21, 31 interact in a magnetically attractive manner and the connecting parts 2, 3 thus attract each other magnetically. The connecting parts 2, 3 can be brought closer to one another by hand, with the magnetic attraction force automatically engaging the connecting parts 2, 3 when they come close to a certain extent, thus causing the connection of the connecting device 1 to be established. An imprecise attachment of the connecting parts 2, 3 to one another is therefore sufficient, with the connection then being established largely automatically.

7A and 7B, the base portion 300 of the main body 30 of the second connecting part 3 comes into contact with the engaging projections 240, 241 from above along the closing direction X, as shown in FIG 8A, 8B. Due to the inclined slide bevels 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 rear edge 304, which can be seen in Fig. 8B, with the bottom surface 230 can come into contact in the receiving opening 23 of the first connecting part 2 and thereby slides in a guided manner along the bottom surface 230 without the blocking element 303 getting caught prematurely.

If the base section 300 has slipped off the engagement projections 240, 241 and the base section 300 has thus passed the engagement projections 240, 241 in the closing direction X, the engagement section 341 formed on the peripheral edge of the base section 300 now slides, supported by the magnetic attraction of the Magnetic devices 21, 31 engage in an engagement direction Y with the engagement projections 240, 241, as can be seen from FIGS. 9A, 9B and 10A, 10B. This movement along (approximately) the direction of engagement Y takes place in a magnetically assisted manner, with a load force (introduced via the belt 4) also being able to assist in engaging.

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 shown in the transition from Fig. 10A, 10B to Fig 11A-11D.

In the connected position shown in FIGS. 11A-11D, the blocking element 303 lies in the recess 231, and the base section 300 with the base surface 302 formed thereon lies flat against the bottom surface 230 within the receiving opening 23 of the first connecting part 2, such as this can be seen in particular from the sectional view according to FIG. 11B.

In the connected position, the base portion 300 faces the support portion 233 with a (front) edge portion 305 and bears against the support portion 233 . If a force is introduced into the second connecting part 3 via the belt 4, this force is absorbed and dissipated by the supporting contact of the base section 300 on the support section 233.

As can be seen from Fig. 11C and 11 D, 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 contact along an arc-shaped support line or surface between the edge section 305 on the base section 300 and the support portion 233.

The support portion 233 is disposed with a central portion viewed along the transverse direction Q between the engaging projections 240, 241 and spaced apart from the engaging projections 240, 241 along the engaging direction Y at the central portion. The support section 233 extends in the cross-sectional plane according to Fig. 11 D in an arc to below the engagement projections 240, 241 and beyond, so that there is a planar support for the base section 300 in the middle between the engagement projections 240, 241 and also directly in the area of the engagement projections 240, 241 is created. In the connected position, the belt 4 on the connecting part 3 is arranged approximately at the height of the engagement projections 240, 241 on the connecting part 2 or below the engagement projections 240, 241. This has the effect that belt forces introduced via the belt 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, in particular along the height direction H .

In the connected position and with 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 when a force is applied via the belt 4 create symmetrical support to the belt 4.

In the connected position, the magnetic devices 21, 31 interact magnetically and thus hold the connecting parts 2, 3 in the connected position.

Due to the engagement of the blocking element 303 in the recess 231, a tangential displacement of the connecting parts 2, 3 against the direction of engagement Y to one another is also blocked. In the connected position, blocking element 303 lies in recess 231 in such a way that blocking element 303 is received between boundary walls 236 that create the blocking section and is in blocking contact with arcuate boundary walls 236, so that blocking element 303, counter to engagement direction Y, does not move towards the

Boundary walls 236 can be moved.

Due to the rotationally symmetrical shape of the blocking element 303 and the circular-cylindrical shape of the base section 300, the connecting part 3 can in the connected position along a circumferential direction U (see Fig. 1) about a rotation axis R within the receiving opening 23 of the connecting part 2 at any angle about a rotation axis R while maintaining the connecting engagement between the connecting parts 2, 3 and also the locking of the blocking element 303 in the recess 231 . This rotatability also allows the connecting parts 2, 3 to be attached to one another in any rotational position, with the connecting parts 2, 3 being aligned with one another when the belt 4 is loaded so that the belt 4 comes to lie between the engagement projections 240, 241 and thus the connecting part 3 is symmetrically supported on the connecting part 2. Due to the twistability, the connecting parts 2, 3 can be attached to one another in a position-tolerant manner, which makes establishing the connection easy and convenient.

As can be seen from Figs. 10A-10C, the base portion 300 dips with a front edge portion 305 when sliding under the engaging projections 240, 241 into the immersion hole 232, which is both the bottom surface 230 and the recess

231 is deepened. By immersing the edge section 305 into the immersion opening 232, the blocking element 303 can slide into the recess 231 and the engagement of the engagement section 341 formed on the base section 300 with the engagement projections 240, 241 can be established. In addition, the angular range of an opening force applied to the actuating section 40 (tab) can be increased and jamming of the edge section 305 during opening can be prevented.

In the connected position, the front edge portion 305 of the base portion 300 then lies on a form-fitting portion in the form of a between the plunge opening

232 and the support portion 233, located at the height of the bottom surface 230 step 234, as can be seen in particular from Fig. 11B. By resting the base section 230 on the step 234, the connecting part 3 is additionally supported against tilting relative to the connecting part 2.

Alternatively, the form-fitting section can also be formed, for example, by a notch or the like on the support section 233, in which the base section 300 engages with the edge section 305 and is thus supported on the support section 233 against tilting, which occurs with a movement of the edge section 305 on the Support section 233 in the closing direction X goes down.

In the connected position according to FIGS. 11A to 11D, the form-fitting section in the form of the step 234 counteracts in particular tilting when the belt 4 is subjected to a load. The second connecting part 3 rests with its base body 30 in the connected position with a first area, formed by the rear area (with respect to the engagement direction Y), on the bottom surface 230 of the base body 20 of the first connecting part 2 . In a second, in the direction of engagement Y In the adjoining area, formed by the area above the immersion 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 . The second base body 30 rests on the step 234 with a third area adjoining the second area in the engagement direction Y, formed by the front edge section 305 of the base section 300, so that in the connected position there is support in the manner of a two-point support is created, with a free space created in between in the area of the immersion opening 232.

In the loaded position, the base section 300 is loaded with the front edge section 305 against the support section 233 and is thus held in contact with the step 234 in a self-reinforcing manner.

If the connecting parts 2, 3 are to be separated from one another, the sequence of movements according to FIGS. 7A, 7B to 11A-11D is essentially reversed. In particular, to separate the connecting parts 2, 3, a user can grip 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 grasping the connecting part 3 lift its rear end off the floor surface 230 and thus tilt the connecting part 3 out of the connected position according to FIGS. 11A-11D in relation to the connecting part 2 in such a way that the base section 300 slides off the step 234 with the front edge section 305 and the blocking element 303 slides out of the recess 231 as shown in Figs. 10A and 10B. In this way, the blockage counter to the direction of engagement Y between the connecting parts 2, 3 is removed, so that the connecting part 3 can be pulled out of engagement from the connecting part 2 counter to the direction of engagement Y and the connecting parts 2, 3 can thus be detached from one another.

In this case, the tilting takes place in a tilting plane which is directed perpendicularly to the bottom surface 230, namely through the closing direction X and the engagement direction Y. The tilting takes place approximately about a tilting axis K (see FIGS. 10A and 10B) in such a way that the connecting part 3 executes a swiveling movement in the tilting plane perpendicular to the tilting axis K and the blocking element 303 is thus lifted out of the recess 231 so that the connecting parts 2, 3 are moved towards one another counter to the direction of engagement Y and can thus be separated from one another. If the connection of the connecting parts 2, 3 is to be released, in particular when the connecting device 1 is unloaded, the connecting parts 2, 3 are tilted relative to one another and, in particular, are also moved relative to one another in the opposite direction to the direction of engagement Y, so that the front edge section 305 (forming the third area) of the base section 300 slides off the step 234 and enters the area of the immersion opening 232, as can be seen in FIG. 10B. The positive-locking section created by the step 234 thus no longer counteracts tilting, so that the connecting parts 2, 3 can be separated from one another comfortably and easily via the actuating section 40 when tilted.

12A to 12F show the connecting device 1 in a twisted 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 a (any) twisted position, and in any rotational position the Engaging portion 341 of the second connecting part 3 can be brought into engagement with the engaging projections 240, 241 of the first connecting part 2. In the connected position, the second connecting part 3 can be rotated 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 with the engagement of the blocking element 303 in the recess 231.

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. In this case, the engagement projections 240, 241 are arranged laterally 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).

If, on the other hand, the second connecting part 3, as can be seen from FIGS. limp deformation of the belt 4, as can be seen in particular from FIGS. 12B and 12D. When twisting, the belt 4 slides (depending on the direction of rotation) onto one of the engagement projections 240, 241 and is deformed as a result, so that the belt 4 can be moved over the respective engagement projection 240, 241. For example, as can be seen from FIG. 1 in conjunction with FIG. 6C , the strap 4 exits the attachment portion 301 above the base portion 300 at an exit line 306 which is curved to conform to the cylindrical shape of the attachment portion 301 . The belt 4 is here beyond the exit line 306, i.e. outside of the fastening section 301, not connected to the base section 300 in the region of the protruding edge section forming the engagement section 341, but can be moved freely relative to the base section 300 and, in particular, can be lifted off the base section 300. which enables the belt 4 to be deformed to slide onto the engagement projection 240, 241 when the connecting part 3 is twisted relative to the connecting part 2 in a smooth manner.

The exit line 306 is offset radially inwards with respect to the front edge section 305 of the base section 300 and is thus spaced radially from the edge section 305 . The belt 4 thus emerges from the fastening section 301 along a line set back in relation to the edge section 305 .

The exit point 306 is radially spaced relative to the axis of rotation R, about which the connecting parts 2, 3 can be rotated relative to one another in the connected position, with the exit point 306 being arranged on a side of the fastening section 301 facing the engagement projections 240, 241 when the connecting device 1 is loaded.

The exit line 306 can be arranged here, viewed along the direction of engagement Y, 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 engagement Y) from the axis of rotation R than the engagement projections 240, 241.

As can be seen from FIG. 11C, in the exemplary embodiment shown, the exit point 306 is arranged at approximately the same axial position along the engagement direction Y as the engagement projections 240, 241.

From the position according to FIGS. 12A to 12F, the connecting part 3 can also be rotated further. In principle, the connecting part 3 can be rotated at any desired angle relative to the connecting part 2 . Under load between the straps 4, 5, the connecting parts 2, 3 move back automatically into the position shown in FIG.

Attaching or detaching the connecting part 3 to or from the connecting part 2 is basically possible in any rotational position.

In the exemplary embodiment according to FIGS. 1 to 12A-12F, the connecting device 1 realizes a belt strap closure via which belts can be connected to one another. In the connected position, a load direction determined by the straps is generally along the direction of engagement Y.

In a further embodiment shown in FIGS. 13 to 22A-22D in the form of a belt buckle, 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 main body 30 of the second closure part 3 into the receiving opening 23 and via a circumferential engaging section 341 with an arcuate engaging projection 240 on a wall section of the receiving opening 23 is engaged.

In the exemplary embodiment shown, a belt 4 is firmly connected to the main body 30 of the connecting part 3 via a fastening section 301 formed on the base section 300 . The belt 4 emerges from the attachment section 301 at an exit location 306 along a straight exit line (see, for example, FIG. 17A in conjunction with FIGS. 18B and 19B) and is not connected to the base section 300 beyond the exit line 306, but is free of the attachment portion 301 extends.

The linearly extended exit location 306 may 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 inside the engagement projection 240, but other areas are radially at a greater distance from the axis of rotation R than the engagement projection 240. It is also conceivable, however, for the exit point 306 to be arranged completely radially inside the engagement projection 240 is. It is also conceivable that the exit point 306 is arranged completely radially outside of the engagement projection 240, ie at a greater radial distance from the axis of rotation R.

ADJUSTED SHEET (RULE 91) ISA/EP The base section 300 has a circular-cylindrical, disc-shaped basic shape and forms a base surface 302 on a side facing the connecting part 2 .

Projecting from the base surface 302 is the spigot element 340 , which has a mushroom shape and carries the engagement section 341 , which extends circumferentially around the closing direction X and implements an engagement device 34 . In the exemplary embodiment shown, the engagement section 341 is thus spatially separated from the base section 300 in that the engagement section 341 is spaced apart from the base section 300 along the closing direction X.

For example, as can be seen from FIG. 180 , in the illustrated embodiment, the exit line 306 is located axially along the engaging direction Y at approximately the same position as the engaging portion 341 .

In the exemplary embodiment shown, an inclined surface 342 in the form of a conical surface is formed on the engagement section 341, with which the engagement section 341 runs onto the engagement projection 240 within the receiving opening 23 when the connection part 3 is placed on the connection part 2, so that the connection part 3 moves counter to the direction of engagement Y is offset from the connector part 2 and the engagement portion 341 is moved past the engagement projection 240 until the engagement portion 341 can be brought into engagement with the engagement portion 240 in the engagement direction Y.

The connecting parts 2, 3 each have a magnetic device 21, 31 (see FIGS. 14A, 14B), which are magnetically attractive opposite one another along the closing direction X and thus support the attachment of the connecting parts 2, 3 in the closing direction X magnetically.

In the illustrated embodiment, the disk-shaped base portion 300 radially overhangs the engagement portion 341 on the trunnion member 340, as can be seen in FIGS. 17A, 17B and 18A, 18B.

When attaching the connecting parts 2, 3 to each other, shown in the sequence according to FIGS Engaging portion 341 with the formed thereon

ADJUSTED SHEET (RULE 91) ISA/EP Sloping surface 342 comes into contact with the engagement projection 240 in the receiving opening 23, as can be seen from Fig. 20B, and is moved past the engagement projection 240 by sliding, as is the case in the transition from Fig. 20A, 20B to Fig. 21A , 21B can be seen.

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 move into the connected position according to Fig. 22A-22D.

In the connected position, the engagement section 341 on the pin element 340 is in engagement with the arcuately curved 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 is in this case a blocking section 238 in the form of a blocking section 238 in the engagement direction Y facing the receiving opening 23 protruding projection element. In this way, the blocking section 238 prevents a tangential movement of the pin element 340 in the receiving opening 23 counter to the engagement direction Y, so that the engagement between the engagement section 341 and the engagement projection 240 is blocked.

In the connected position, the base portion has a peripheral, outer edge portion 305 in abutment with a support portion 233 projecting the engagement projection 240 in the engagement direction Y, as seen in Figure 22B. The support section 233 thus provides support on the base section 300 in the engagement direction Y, so that when there is a load between the connecting parts 2, 3, forces along the load direction corresponding to the engagement direction Y are absorbed and dissipated on the support section 233.

As can also be seen from FIG. 22B, in the area of the support section 233 a form-fitting 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 the connecting parts 2, 3 from becoming unintentionally released under load. As can be seen from Fig. 22B in conjunction with Fig. 21B, the step 234 is followed by a plunge opening 232, which serves to provide a free space into which the base section 300 can be inserted when tilted relative to the connecting part 2 , 3, as can be seen from FIG. 21B.

If the connecting parts 2, 3 are to be separated from one another, 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 can be seen in Fig. 21 B can be seen. The base section 300 dips into the immersion opening 232 with a front area facing the support section 233, which makes it easier to tilt the connecting part 3 relative to the connecting part 2 in order to release the connecting parts 2, 3 from one another.

In the connected position, analogous to the initial example according to FIGS. 1 to 12A-12F, tilting under load is counteracted via the support on the step 234 . A free space is created via the immersion opening 232 in an area adjoining the step 234 counter to the engagement direction Y, into which the base section 300 can enter with its peripheral edge section when the connecting parts 2, 3 are tilted relative to one another to separate the connection.

In the embodiment shown in Figs. 13 to 22A-22D, the engaging portion 341 is formed not on the disc-shaped base portion 300 but on the pin member 340 protruding from the base portion 300 along the closing direction X, so that the engaging portion 341 along the closing direction X from the base portion 300 is spaced and also the peripheral edge portion 305 of the base portion 300 is disposed radially outside of the engaging portion 241.

The engagement portion 341 is thus spatially separated from the base portion 300 . The production of a form fit or force form fit via the engagement section 341 separately from the support of the base section 300 on the support section 233 and the form-fit section 234 is also functional. This can, for example, support the base section 300 for load absorption on the support section 233 and also for counteracting against tilting over the form-fitting section 234 favor by the base portion 300 can provide a comparatively large lever arm compared to the engagement portion 341 for support.

In the embodiment according to FIGS. 13 to 22A-22D, the support section 233 is formed rigidly on the base body 20 of the connecting part 2 by a surface section which extends perpendicularly to a direction radial to the closing direction X and is curved in an arc around the closing direction X, such as this can be seen from FIG. 22B in combination with FIG. 16A. Likewise, the form-fitting section 234 is curved in an arc in the form of the step and thus forms a support for the edge section 305 of the base section 300 .

In contrast, in a modified embodiment shown in FIGS. 23A-23C, an arcuate support section 233 extending obliquely to the closing direction X fulfills the function of the support section 233 and the positive-locking section 234 of the embodiment according to FIGS. 13 to 22A-22D. The obliquely extended support section 233 of the embodiment according to FIGS a movement of the base portion 300 in the front region in the closing direction X.

Otherwise, the exemplary embodiment according to FIGS. 23A-23C is identical to the exemplary embodiment according to FIGS. 13 to 22A-22D, so that reference should also be made to the preceding explanations.

24-50 show exemplary uses of a connecting device 1, as has been described with reference to the exemplary embodiments according to FIGS. 1-23C.

A connecting device 1 can be used, for example, on a bag or backpack, as shown in Figs. 24-31. The connecting device 1 can be used to connect strap ends (FIGS. 24, 27, 28 and 31), to connect straps to a bag body (FIGS. 25, 26 and 30) or to close a lid of a bag or a backpack or to attach an object on the bag or backpack (Fig. 29) are used.

ADJUSTED SHEET (RULE 91) ISA/EP The connecting device 1 can be used as a closure for a shoe (FIGS. 32 and 33), as a closure for pockets on a textile object, for example a jacket or vest (FIGS. 34), or as a closure for a medical bandage (FIGS. 35- 37) serve.

The connecting device 1 can be used as a closure for a fanny pack (FIG. 38) or for a tool belt (FIG. 39).

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).

The connecting device 1 can be used as a fastener for a strap on a musical instrument, for example a guitar (FIG. 41).

The connecting device 1 can be used, for example, to attach a belt to a bicycle, for example to a luggage rack or a basket on a bicycle (FIG. 42).

The connection device 1 can also serve as a closure for a helmet (FIG. 43).

The connecting device 1 can provide a belt buckle for tying up an object, for example a mat (FIG. 44).

The connecting device 1 can also provide a buckle for a belt system for stowing luggage in a vehicle, for example a car (FIG. 45).

The connecting device 1 can be used as a closure for an adjustment system in the interior of a vehicle, for example for a sun blind (FIG. 46).

The connecting device 1 can provide a holder for items on a shelf, for example key fobs on a key shelf (Figure 47).

Connecting devices 1 can serve as a holder for a camera, for example for connecting the camera with straps (Fig. 48). A connecting device 1 can serve as a clasp for a wristwatch (FIG. 49) or a bracelet (FIG. 50).

In all of the applications mentioned, the rotatability of the connecting parts 2, 3 solves important aspects of the requirements of the respective application. Conventional plug-in fasteners, as are often used for such applications, cannot be rotated.

Other applications are conceivable and possible.
