AI Technical Summary
Existing connection devices fail to provide a simple, comfortable, and secure method for connecting parts while allowing for position-tolerant assembly and resilient hold in a connected position, often leading to unwanted tilting or separation.
A connection device with a first connecting part featuring a rigid section and a second connecting part with a magnetic device, where the second part is designed to interfere with the first part along a specific intervention direction, creating a secure and resilient connection through a shaped form that supports the second base body, allowing for easy adjustment and separation.
The connection device enables secure, resilient, and comfortable assembly and disassembly by using magnetic attraction and a shaped form to maintain the connection, preventing unwanted tilting and ensuring a safe hold without loading the parts excessively.
Description
[0001] The invention relates to a connecting device according to the preamble of claim 1.
[0002] Such a connecting device comprises a first connecting part having a first base body and at least one engagement projection rigidly arranged on the first base body. The connecting device further comprises a second connecting part which can be attached to the first connecting part in a closing direction and which has a second base body with an engagement portion rigidly arranged on the second base body, wherein the engagement portion can be brought into engagement with the at least one engagement projection of the first connecting part along an engagement direction different from the closing direction, such that when the first connecting part and the second connecting part are in a connected position, the engagement portion engages with the at least one engagement projection of the first connecting part. The first connecting part has a first magnetic device, and the second connecting part has a second magnetic device.The first magnetic device and the second magnetic device cooperate in a magnetically attractive manner to assist in the attachment of the first connecting part and the second connecting part to one another along the closing direction.
[0003] In the connecting device, one or more engagement projections are rigidly formed on the first base body of the first connecting part. The second connecting part can be engaged with the at least one rigid engagement projection by bringing an engagement portion of the second connecting part into engagement with the at least one engagement projection of the first connecting part. The first connecting part and the second connecting part are attached to one another along a closing direction, along which magnetic devices of the connecting parts provide a magnetic attraction force, so that the connecting parts are drawn towards one another along the closing direction. In contrast, the engagement of the engagement portion of the second connecting part with the at least one engagement projection of the first connecting part takes place along an engagement direction that is directed transversely to the closing direction.In the connected position, the engagement portion engages with the at least one engagement projection in a form-fitting or force-fitting manner, so that the connecting parts are held together.
[0004] The fact that the engagement direction is different from the closing direction is to be understood in this case to mean that the engagement direction is directed perpendicular or at an oblique angle to the closing direction. The engagement direction is not necessarily directed exactly perpendicular to the closing direction, but can extend at an oblique angle to the closing direction. However, the engagement direction is not directed along the closing direction, and in particular not opposite to the closing direction. In a closure device known from EP 3 616 553 A1 for releasably 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 and can be tightened by connecting the connecting parts to one another.
[0005] EP 3 192 388 B1 discloses a closure device 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.
[0006] From WO 2014 / 090926 A1 a closure device for detachably connecting two parts is known,
[0007] In a connecting device of the type mentioned, it is generally desirable to enable the connecting parts to be connected in a simple, comfortable, and tactile manner for the user. The connection should preferably be position-tolerant, allowing for imprecise positioning of the connecting parts. When the connecting parts are connected, a secure, resilient connection should be created.
[0008] 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, comfortable manner and in a connected position provide a secure, resilient hold on one another.
[0009] This object is achieved by an article having the features of claim 1.
[0010] Accordingly, the first base body has a form-fitting section against which the second base body 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, wherein the second base body rests against the first base body in a first region in the connected position, and does not rest against the first base body in a second region adjoining the first region in the engagement direction, so that a free space is formed between the first base body and the second base body when viewed along the closing direction, and a third region adjoining or spaced from the second region in the engagement direction is supported on the form-fitting section.
[0011] The first base body has a form-fitting section against which the second base body 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 front region of the first base body with respect to the engagement direction and is rigidly formed on the first base body. The second base body is supported on the form-fitting section, in particular against movement in the closing direction, such 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.
[0012] In the connecting device, a load direction along which a load force acts on the second connecting part during intended loading in a loaded state can preferably be directed with at least one directional vector component in the engagement direction. In the loaded state, the second connecting part is thus loaded in the engagement direction relative to the first connecting part and thus in the direction of engagement with the at least one engagement projection rigidly formed on the first connecting part.
[0013] Due to such a load, a torque can act on the second connecting part, which loads the second connecting part in the direction of tilting in a transverse direction perpendicular to the closing direction and the engagement direction. To counteract such tilting, the form-fitting section is formed on the first base body, which provides support for the second base body, particularly in a front area, so that the second base body is supported against tilting, particularly in the transverse direction, and thus a load cannot lead to an unintentional separation of the connecting parts from one another.
[0014] The form-fitting section and the support created thereby ensure that the connecting parts are held together securely, reliably and resiliently in the connected position, without load forces being able to cause the connecting parts to become detached from one another.
[0015] In the connected position, the second base body rests against the first base body in a first region. For example, the second base body can rest with a base surface against a bottom surface of the first base body, so that in the first region there is a flat contact between the second base body and the first base body. In a second region adjoining the first region in the engagement direction, the second base body, on the other hand, does not rest against the first base body, so that, viewed along the closing direction, a free space is formed between the first base body and the second base body. A third region adjoins this second region or is spaced from the second region along the engagement direction. This third region of the second base body is supported on the form-fitting section of the first base body.
[0016] This provides support for the second base body on the first base body in the manner of a two-point support with a free space created between them (it being noted that a support can also exist in more than two areas). The third area can be formed, in particular, in a front area of the second base body in the engagement direction, so that the third area can provide support, in particular, to prevent tilting in a transverse direction perpendicular to the closing direction and the engagement direction. In contrast, the first area can be formed, with respect to the engagement direction, in a rear area of the second base body.
[0017] The free space created between the second region of the second base body and the first base body can, in particular, enable the connecting parts to be easily attached to one another and separated from one another. For example, when separating the connecting parts from one another, it may be necessary or advantageous to first move the second connecting part a (small) distance counter to the direction of engagement with the first connecting part and then to tilt it transversely to the first connecting part. During tilting, for example, the second and / or third region can move into the free space, thereby enabling a tilting movement of the second connecting part relative to the first connecting part in a haptically pleasant and comfortable manner for a user.
[0018] In other words, in the connected position the second connecting part is fixed to the first connecting part, particularly under load, with restrictions on the degrees of freedom. When opened, the connecting parts are moved (for example within the scope of play) against the direction of engagement or by slight tilting towards one another, so that the second connecting part slides off the form-fitting section and the restrictions on the degrees of freedom are reduced. This enables the connecting parts to tilt towards one another. By immersing themselves in the free space during opening, after an initial movement, a (stronger) tilting or pivoting movement of the connecting parts towards one another is enabled, which enables a haptically pleasant and comfortable separation of the connecting parts from one another for the user.
[0019] Because the at least one engagement projection is formed rigidly and non-deformably (under a properly acting load) on the first base body of the first connecting part, the engagement projection can reliably absorb and dissipate forces when engaging with the engagement section of the second base body. The at least one engagement projection is preferably formed integrally with the first base body of the first connecting part, with the first base body being designed to be rigid and non-deformable overall.
[0020] In this context, "non-deformable" refers to a substantially rigid geometry and material selection of the base body, which ensures that the base body of the first connecting part, with the engagement projection formed thereon, does not deform under a specified load; thus, the base body is not elastic. For example, the base body of the first connecting part can be made of metal or a hard plastic material.
[0021] Likewise, the base body of the second connecting part with the engagement section formed thereon is rigid and non-deformable and is made, for example, of metal or a hard plastic material.
[0022] The joining of the connecting parts to one another is magnetically assisted. 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 assist the joining of the connecting parts to one another. The magnetic devices act magnetically attractively along the closing direction, so that the magnetic devices exert a magnetic attraction force along the closing direction and pull the connecting parts toward one another during joining along the closing direction. The magnetic devices can, for example, each be formed by a permanent magnet.However, it is also possible to design one of the magnetic devices with a permanent magnet and the other of the magnetic devices with a magnetic armature and thus with a passive magnetic element.
[0023] In one embodiment, the second base body is designed to move the second and / or third region closer to the first base body in the closing direction, reducing the free space, when the first connecting part and the second connecting part tilt relative to one another, for example, when the connecting parts are separated from one another. For example, during such a tilting, the third region of the second base body can move into the free space, with the third region disengaging from the form-fitting section, thus enabling the connecting parts to tilt relative to one another.
[0024] In one embodiment, the first base body has an insertion opening into which the third region of the second base body can insert when the second connecting part is tilted relative to the first connecting part in the closing direction. The insertion opening can be formed, in particular, in a front region of the first base body (with respect to the engagement direction) and can be shaped, for example, as a recess on the first base body. The second base body can insert into the insertion opening, in particular with a front edge section forming the third region, when the connecting parts are tilted relative to one another (during connection or separation).
[0025] The insertion opening can, for example, be shaped as a recess relative to a base surface of the first base body. In this case, the insertion opening adjoins the base surface, for example, but is recessed relative to the base surface and thus set back along the closing direction. In the connected position, the second base body is in contact with the base surface, for example, via its first region.The immersion opening can extend in particular below the at least one engagement projection and thus provide a space in the region of the at least one engagement projection, from which the second region of the second base body is spaced in the connected position to create the free space (with respect to the closing direction) and into which the third region of the second connecting part can immerse when the connecting parts are placed against one another to close the connecting device and also when the connecting parts are separated from one another to open the connecting device.
[0026] In general, a play between the engagement section of the second connecting part and the at least one engagement projection of the first connecting part can facilitate tilting of the connecting parts relative to one another for establishing the connection and also for separating them. Tilting is also facilitated by the free space between the second region of the second base body and the first base body, in that the third region of the second base body, after a previous slight actuation counter to the engagement direction and subsequent tilting actuation, can slide off the form-fitting section and enter the free space.
[0027] The immersion opening can be designed as a recess or as a through-opening on the first base body.
[0028] The form-fitting section can be formed, for example, by a step on which the second base body rests in the connected position. The form-fitting section can, in particular, have a surface section directed perpendicularly or obliquely to the closing direction, which provides support for the second base body.
[0029] In another embodiment, the form-fitting section can also be shaped as an engagement opening, for example, in the form of a notch. The form-fitting section provides support on the first base body perpendicular to the engagement direction, namely along the closing direction, so that the connecting parts in the connected position cannot easily tilt toward each other under load, but are supported against (unintentional) tilting by the form-fitting section.
[0030] In one embodiment, the form-fitting section is spaced apart from the at least one engagement projection, viewed along the closing direction. The form-fitting section can extend above or below the at least one engagement projection, viewed along the closing direction.
[0031] Additionally or alternatively, the form-fitting section can be spaced from the at least one engagement projection, viewed along the engagement direction. The form-fitting section is thus 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 upstream of the at least one engagement projection in the engagement direction. The form-fitting section can be arranged radially outside the at least one engagement projection, particularly in an advantageous rotatable design. In this way, favorable support can be created via the form-fitting section to prevent the connecting parts from tilting relative to one another, in that the second base body can come into contact with the form-fitting section with a favorable lever arm when loading forces act between the connecting parts.
[0032] In one embodiment, the first base body has a support section rigidly formed on the first base body, wherein in the connected position the second base body is supported by the support section for load absorption along the engagement direction. The second base body can, for example, form an edge section which, when loaded in the engagement direction, comes into supporting contact with the support section. The edge section can, for example, be formed in a front region of the second base body, wherein the edge section can also run circumferentially around the second base body. The support section is formed in a front region of the first connecting part with respect to the engagement direction, such that the support section can provide support for the second base body in the engagement direction.When the second connecting part is loaded relative to the first connecting part in the engagement direction, the edge section is pressed against the support section and thus supported on the support section. In the connected position, the second base body can thus come into contact with the support section on the first base body of the first connecting part via the edge section, so that loading forces can be transferred from the second connecting part to the first connecting part.
[0033] It is conceivable that the edge section always engages the support section in the direction of engagement in the connected position. Alternatively, it can also be provided that in an unloaded position, the edge section does not engage the support section in the direction of engagement, but only comes into contact with the support section when the connecting parts are loaded relative to each other.
[0034] Via the support section and the support of the edge section of the second base body on the support section, forces can advantageously be introduced from the second connecting part into the first connecting part. For example, when the connecting device is designed as a belt fastener, a load direction along which a force acts between the connecting parts when the connecting device is used as intended can be directed along the engagement direction, so that when loaded, the engagement section is loaded in the direction of engagement with the at least one engagement projection. In this case, the edge section of the second base body comes into supporting contact with the support section, so that forces acting in the engagement direction are diverted via the contact of the edge section with the support section.The at least one engagement projection serves in particular for support along the closing direction and thus for ensuring that the connecting parts are held together, whereby loading forces in the engagement direction are primarily absorbed and diverted via the support section.
[0035] In one embodiment, the support section is curved in an arcuate manner in a cross-sectional plane perpendicular to the closing direction. The edge section can also be curved accordingly, with the arcuate shape of the edge section advantageously complementing the arcuate shape of the support section, thus allowing the edge section to come into planar contact with the support section.
[0036] In one embodiment, the support section is spaced apart from the at least one engagement projection, viewed along the closing direction. The support section can extend above or below the at least one engagement projection, viewed along the closing direction.
[0037] 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 thus 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 upstream of the at least one engagement projection in the engagement direction, such that the support section is arranged radially outside the at least one engagement projection. In this way, favorable support can be created via the support section in that the second base body can come into contact with the support section with a favorable lever arm when loading forces act between the connecting parts.
[0038] In one embodiment, the support section is formed by a surface section that is parallel or oblique to the closing direction. The support section is rigidly formed on the first base body of the first connecting part. Under load, the support section on the first connecting part comes into contact with the second base body of the second connecting part, so that load forces acting in the engagement direction can be effectively absorbed and dissipated.
[0039] In one embodiment, the second connecting part can be rotated about the closing direction relative to the first connecting part in the connected position. This can, on the one hand, enable the connecting parts to be placed against one another in an angularly tolerant manner. It is also possible to rotate the second connecting part relative to the first connecting part when the connecting parts are in the connected position. Upon rotation, the engagement section and the at least one engagement projection retain their engagement. In addition, the engagement is blocked by a blocking section of the first base body (described below) even during rotation. Rotating the connecting parts about the closing direction relative to one another in the connected position therefore does not lead to the connecting parts becoming separated from one another.
[0040] The rotatability between the connecting parts in the connected position can enable any rotational movement through any angle. However, it is also conceivable that the movement of the connecting parts is limited to a predetermined angle of rotation, for example, by stops or the like. The angle of rotation is preferably greater than 10°, more preferably greater than 20°, particularly preferably greater than 45° or even greater than 90°.
[0041] In one embodiment, the first connecting part has a blocking section rigidly arranged on the first base body, which is designed to cooperate 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 connected position, the second connecting part is rotatable relative to the first connecting part about the closing direction. Upon rotation, the engagement of the engagement section with the at least one engagement projection and the blocking of the engagement by the blocking section remain intact. The second connecting part is tiltable relative to the first connecting part in order to release the blocking counter to the engagement direction in order to separate the first connecting part and the second connecting part from one another and to enable the engagement section and the at least one engagement projection to be disengaged.
[0042] The connecting parts are to be joined together along the closing direction, with the joining of the connecting parts being magnetically assisted by the magnetic devices of the connecting parts. During the joining process, the connecting parts are magnetically attracted to each other by the magnetic device and are also magnetically held together in the connected position.
[0043] When the connecting parts are attached, the engagement section of the second connecting part engages with the at least one engagement projection of the first connecting part in the engagement direction pointing transversely or obliquely to the closing direction, so that in the connected position there is a positive or force-locking connection between the connecting parts and the connecting parts are thus held against one another in a load-bearing manner by the engagement of the engagement section with the at least one engagement projection.
[0044] The engagement between the engagement portion of the second connecting part and the at least one engagement projection of the first connecting part is secured in the connected position by the blocking portion of the first connecting part, which is rigidly formed on the first base body of the first connecting part. The blocking portion cooperates with an associated portion of the second connecting part in a blocking manner counter to the engagement direction, and the engagement portion thus cannot be moved counter to the engagement direction toward the at least one engagement projection, at least not without removing the blocking. Due to the blocking effect of the blocking portion, the engagement portion is thus locked in its engagement with the at least one engagement projection, so that the connecting parts are secured relative to one another in the connected position.
[0045] The connecting parts are held in the connected position by the magnetic effect of the magnetic devices, such that the connecting parts are locked against each other by the blocking section of the first connecting part, counter to the direction of engagement. The connecting parts cannot be separated from each other by a (pure) sliding movement counter to the direction of engagement.
[0046] Rather, to release the connecting parts from one another, it is necessary for the connecting parts to be tilted relative to one another in order to move the second connecting part in a tilting plane spanned by the closing direction and the engagement direction relative to the first connecting part such that the second connecting part can be moved toward the blocking portion opposite to the engagement direction. By tilting the second connecting part relative to the first connecting part, the blocking effect of the blocking portion can be canceled, so that the second connecting part can be moved over the blocking portion and thus the engagement portion of the second connecting part can be disengaged from the at least one engagement projection of the first connecting part.
[0047] The blocking effect of the blocking section rigidly arranged on the first base body of the first connecting part ensures that the second connecting part cannot be moved linearly against the engagement direction, but must be tilted in a tilting plane spanned by the closing direction and the engagement direction in order to separate the connecting parts from one another. The tilting movement can occur about a defined tilting axis. However, the tilting movement can also occur along a curved path of movement located in the tilting plane, whereby the second connecting part is tilted relative to the first connecting part as a result of the tilting movement. The tilting movement can be superimposed by a linear movement against the engagement direction and / or against the closing direction.
[0048] It should be noted that the connecting parts can be tilted relative to one another to separate them. However, the connection between the connecting parts is not established in a linear closing movement, but rather by the connecting parts being placed against one another in a wobbling manner while tilted relative to one another and moved into engagement. During the establishment of the connection, the second connecting part can also tilt relative to the first connecting part to enable the engagement portion of the second connecting part to engage the at least one engagement projection of the first connecting part.
[0049] When tilting to separate the connecting parts from one another, the second base body and its third region are disengaged from the form-locking section on the first base body by a slight movement counter to the direction of engagement within the scope of a play. In this case, a play can be provided between the second connecting part and the blocking section of the first connecting part, which allows a (slight) sliding movement of the second connecting part counter to the direction of engagement, or a play can be provided between the second connecting part and the at least one engagement projection, which allows a (slight) tilting movement and a subsequent sliding movement of the second connecting part counter to the direction of engagement.Due to the movement within the play, the third area is released from the positive-locking section, for example, by the third area sliding off the positive-locking section, which is shaped like a step. The connecting parts can then be tilted (more strongly) towards each other, allowing them to be separated.
[0050] The depth of the engagement projection measured along the engagement direction can be greater than the depth of the support surface created by the form-fitting section measured along the engagement direction, so that the third region initially slides off the form-fitting section and only then, upon further movement counter to the engagement direction, does the engagement section of the second connecting part disengage from the at least one engagement projection on the first connecting part.
[0051] In one embodiment, the second connecting part has a blocking element rigidly arranged on the second base body for interacting with the blocking section of the first connecting part. The blocking element is formed on the second base body and protrudes, for example, along the closing direction from a base surface of the second base body. 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 direction of engagement with each other is blocked.However, by tilting the connecting parts relative to each other, the blocking element can be lifted above the blocking section in order to remove the blocking and to move the connecting parts relative to each other while tilting in the opposite direction to the engagement direction, so that the engagement between the engagement section of the second connecting part and the at least one engagement projection of the first connecting part can be removed and the connecting parts can be separated from each other.
[0052] In the connected position, the blocking element is preferably rotatable relative to the blocking section in the closing direction, whereby upon rotation, the blocking of the engagement of the engagement section with the at least one engagement projection remains intact. For example, the blocking element can be circularly cylindrical for this purpose.
[0053] In one embodiment, the first base body has a recess that is at least partially delimited 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, for example, be formed as a depression on a bottom surface of the first base body of the first connecting part. The recess is thus formed into the bottom surface. The blocking element is brought into engagement with the recess when the connecting parts are placed against one another, so that the engagement holds the second connecting part on the at least one engagement projection of the first connecting part.
[0054] In one embodiment, the recess is delimited (in a cross-sectional plane perpendicular to the closing direction) by at least one boundary wall forming the blocking section, which wall extends along a circular arc. The recess can, for example, have a circular basic shape, in which the at least one boundary wall extends in an arc along an (imaginary) circle centered on an axis.
[0055] For example, the recess is defined by two arcuate boundary walls, which together form the blocking section and, in the connected position, accommodate the blocking element of the second connecting part between them, thus blocking 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 a right angle to the base surface and thus provide support surfaces for the blocking element, so that when loaded, the blocking element is supported on the boundary walls and thus blocked relative to the first connecting part.
[0056] In one embodiment, the blocking section has a run-up slope. The run-up slope is designed to provide a sliding guide for the blocking element counter to the engagement direction when the second connecting part tilts relative to the first connecting part. When the connecting parts tilt relative to one another, for example, a blocking element of the second connecting part can come into contact with the run-up slope, so that the blocking element can run onto the run-up slope and thus be moved over the blocking section. Such a run-up slope can thus facilitate the separation of the connecting parts from one another.
[0057] In one embodiment, the second connecting part can be lifted off the first connecting part on a side facing away from the at least one engagement projection, counter to the closing direction, for tilting relative to the first connecting part. In the connected position, the second connecting part engages with the at least one engagement projection on the first base body of the first connecting part via the engagement portion rigidly formed on the second base body. This engagement occurs in a front region of the second connecting part—as seen in the engagement direction.With a rear region with respect to the engagement direction, the second connecting part can be lifted off the first connecting part in the connected position counter 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 be moved to the blocking section of the first connecting part and the engagement section can be brought out of engagement from the at least one engagement projection counter to the engagement direction.
[0058] To make handling easier for a user, the second connecting part can, for example, have an actuating section which a user can grip to tilt the second connecting part relative to the first connecting part. The actuating section can, for example, be formed 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 away from the first connecting part in the opposite direction to the closing direction. However, the actuating section can also be formed, for example, by a recessed grip or another grip section which a user can grip to tilt the second connecting part relative to the first connecting part.
[0059] In one embodiment, 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 multiple engagement projections are provided, each engagement projection can, for example, extend in an arc around the closing direction. Additionally or alternatively, the engagement projections can be arranged in a row along a circumferential direction pointing around the closing direction, so that the engagement projections are arranged in a row 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.
[0060] The at least one engagement projection extends around the closing direction by an angle of less than 180°, preferably less than 150°, in order to enable the engagement portion to be brought into engagement with the at least one engagement projection in the engagement direction.
[0061] 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 protrudes transversely to the closing direction from an associated portion of the first connecting part.
[0062] The undercut can be formed by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.
[0063] Likewise, the engagement portion of the second connecting part preferably forms an undercut with respect to the closing direction. The engagement portion is thus undercut with respect to the closing direction in that the engagement portion protrudes transversely to the closing direction from an associated portion of the second connecting part.
[0064] The undercut can in turn be formed by a surface extending perpendicularly or obliquely (at an acute or obtuse angle) to the closing direction.
[0065] In one embodiment, the engagement portion extends circumferentially along the closing direction. The engagement portion can, for example, be arranged on a pin element and protrude from the pin element transversely to the closing direction.
[0066] For example, the engagement portion is rotationally symmetrical with respect to the closing direction. This allows the engagement portion to be brought into engagement with the at least one engagement projection on the first connecting part in any rotational position of the second connecting part relative to the first connecting part, so that an engagement between the engagement portion and the at least one engagement projection exists in any rotational position of the second connecting part relative to the first connecting part, and the connecting parts can thus be rotated relative to one another without the engagement of the engagement portion with the at least one engagement projection being canceled.
[0067] In one embodiment, the second main body of the second connecting part has a base section.
[0068] In one embodiment, the base portion can form the engagement portion, so that the engagement portion is shaped for engagement with the at least one engagement projection of the first connecting part on the base portion, for example on a circumferential edge portion of the base portion.
[0069] In another embodiment, the engagement portion is spaced apart from the base portion along the closing direction. The engagement portion is thus spatially separated from the base portion, for example, by the base portion extending along a first plane and the engagement portion extending along a second plane spaced apart from the first plane along the closing direction.
[0070] If the engagement portion is spatially spaced from the base portion, the engagement portion is formed, for example, on a pin element that protrudes from the base portion along the closing direction. The engagement portion protrudes from the pin portion along the engagement direction and thus forms an undercut, so that the engagement portion can be engaged with the at least one engagement projection of the first connecting part to establish a positive or non-positive connection.
[0071] The engagement portion can, for example, be formed circumferentially on the pin element. In this way, a mushroom-shaped engagement element can be provided that 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 hold them together in the connected position.
[0072] If the engagement portion is spatially spaced from the base portion, the base portion can extend radially further in the closing direction than the engagement portion and thus project radially beyond the engagement portion. The engagement portion is thus located in a radially inner position, while an outer edge of the base portion is arranged radially outside the engagement portion. In this way, favorable support of the second connecting part on the first connecting part can be created via the base portion when the connecting parts are in their connected position.
[0073] In one embodiment, the base section is, for example, disc-shaped. The base section can, for example, have a circular-cylindrical basic shape with a circular cross-section.
[0074] For example, a fastening section can be formed on the base section, via which a belt is connected to the second connecting part.
[0075] In one embodiment, the base section has a base surface, and the first main body has a bottom surface. The base surface and the bottom surface each extend perpendicular to the closing direction. In the connected position, the base surface on the base section of the second connecting part and the bottom surface on the first main body of the first connecting part face each other.
[0076] For example, in the connected position, there may be contact between the base surface and the bottom surface. When the connecting parts are rotated relative to each other in the closing direction, the base surface and the bottom surface slide against each other.
[0077] However, this is not mandatory. It is also conceivable that in the connected position there is a gap (and thus no contact) between the base surface and the floor surface.
[0078] In one embodiment, the base section can be tilted about a tilt axis perpendicular to the closing direction and the engagement direction relative to the first connecting part in order to tilt the connecting parts relative to one another. The tilting of the connecting parts to separate the connecting parts from one another thus occurs in that the base section is tilted about a tilt axis relative to the first base body of the first connecting part. The tilt axis can be defined by a contact line between the base section and the first base body. However, it is also conceivable that the tilt axis corresponds to an imaginary line that extends through the base section or outside the base section and corresponds to a line about which the base section is pivoted relative to one another when the connecting parts are tilted.
[0079] In one embodiment, the at least one engagement projection has, for example, a sliding bevel that serves as a guide bevel to guide the connecting parts when they are placed against one another so that the connecting parts can be brought into engagement with one another in an easy, preferably largely automatic manner. The sliding bevel is preferably designed to guide the second connecting part, when it is placed against the first connecting part, along the closing direction along the at least one engagement projection such that the second connecting part is offset from the first connecting part counter to the engagement direction and is thereby moved past the at least one engagement projection. After moving past, the second connecting part can then be brought into engagement with the at least one engagement projection of the first connecting part in the engagement direction.By sliding on the at least one engagement projection, the second connecting part is guided relative to the first connecting part such that the second connecting part is moved past the at least one engagement projection. Once the second connecting part has passed the at least one engagement projection with its engagement portion, the engagement portion can be brought into engagement with the at least one engagement projection on the first connecting part in the engagement direction.
[0080] In one embodiment, a belt fastener comprises a connecting device of the type described above. In particular, the second connecting part can be connected to a belt, whereby the belt can be arranged on the second connecting part in a fixed and non-adjustable manner, but can also be adjustable if necessary.
[0081] The first connecting part can also be connected to a belt, but can also be fixedly arranged on an associated assembly, for example a textile article or another article.
[0082] In one embodiment, when the connecting device is used on a belt strap fastener, the first connecting part has two engagement projections that are spaced apart transversely to the closing direction and transversely to the engagement direction such that the belt can be guided between the engagement projections when the first connecting part and the second connecting part are in the connected position. The belt is thus received between the engagement projections, so that the engagement projections on both sides of the belt provide support for the second connecting part relative to the first connecting part.
[0083] In another application, an object fastening device for fastening an object to an assembly may comprise a connecting device of the type described. The object may, for example, be arranged on one of the connecting parts, for example, integrated into the connecting part. The other of the connecting parts, in contrast, is arranged on the assembly, so that the object can be secured to the assembly by connecting the connecting parts.
[0084] The possible uses listed below are intended to illustrate the wide range of applications of the connecting device, but are not intended to be limiting or exhaustive. The connecting device can be used for: Helmet fasteners Horse halters, removable (breast) pouches, bags, backpacks for roll-tops, for closing with (elastic) webbing Jacket fasteners (e.g. on the sleeve, lapel, button placket, or tying up shirt sleeves) Roller blinds in mobile homes, privacy screens Caravan covers Awnings, tarpaulins, camping tents, tent guy ropes Fastening or closing luggage bags or saddle bags (bike, motorbike) Luggage and load securing, or securing bicycles / strollers in and on vehicles Public transport Sorting and securing system for tradespeople in vehicles Strap closure, restraint systems and closure devices for carrying equipment Chest belts, hip belts, shoulder straps Removable handles or carrying straps on bags Sun protection that can be opened up, e.g.on strollers Movable and removable or openable connection of backpack carrying straps Suspension for coat hangers Furniture, for example for attaching seating elements Sleeping bags, sleeping mats, yoga mats (to roll up and fasten) Towel holder Key holder Belts Craftsman's belt with tool for hanging on Removable carrying straps, e.g. on tools and gardening equipment, handles for bags and electrical devices Gloves, shoes, golf bags (to close or attach to one another) Mosquito repellent in a stroller or tent A luggage strap, for example for attaching things in a bicycle basket for components and accessories on the bicycle (speedometer, light, computer, electronic devices, etc.).

[0086] In a Fig. 1 bis 12A-12F In the embodiment shown, 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.
[0087] The connecting parts 2, 3 can generally be attached to one another along a closing direction X, wherein the connecting parts 2, 3 each have a magnetic device 21, 31 in the form of a permanent magnet (or alternatively in the form of a permanent magnet on the one hand and in the form of a magnetic armature on the other hand), which interact in a magnetically attractive manner and attract the connecting parts 2, 3 towards one another along the closing direction X.
[0088] It should be noted that the attachment of the connecting parts 2, 3 may 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 interact in a magnetically attractive manner along the closing direction X and pull the connecting parts 2, 3 toward each other along the closing direction X.
[0089] As can be seen from the exploded views according to Fig. 2A and 2B and the separate views according to Fig. 3A, 3B und 4A-4C As can be seen, the first connecting part 2 has a base body 20, which forms a receiving opening 23 for receiving the second connecting part 3. Arranged on the base body 20 is a strap receptacle 22 in the form of a web and an adjoining opening, to which a strap 5 can be or is attached. 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.
[0090] The receiving opening 23 is formed as a recess on the base body 20. Within the receiving opening 23, a bottom surface 230 is formed in the form of a flat surface extending perpendicular to the closing direction X, with which the second connecting part 3 can be brought into flat contact when inserted into the receiving opening 23 to establish a connection between the connecting parts 2, 3.
[0091] A recess 231 in the form of a depression is formed in the bottom surface 230, into which - as will be described below - a blocking element 303 engages on a base section 300 of the second connecting part 3 when the connecting parts 2, 3 are in the connected position.
[0092] The receiving opening 23 is delimited at a front end by a support section 233, which serves as support and load-bearing for the second connecting part 3 in the connected position. Between the support section 233 and the bottom surface 230, an insertion opening 232 is formed, which serves to facilitate the establishment of the connection as well as the separation of the connecting parts 2, 3, in that an edge section 305 of the base section 300 of the second connecting part 3 can be immersed in the insertion opening 232 when establishing the connection and also when separating the connection, as is shown, for example, in Fig. 10B is evident and will be described below.
[0093] The immersion opening 232 is shaped as a recess relative to the bottom surface 230 and adjoins the bottom surface 230 such that the immersion opening 232 is located between the support section 233 and the bottom surface 230. At the transition between the immersion opening 232 and the bottom surface 230, a beveled transition surface 237 is formed, which serves as a guide for the second connecting part 3 for establishing the connection as well as for separating the connection.
[0094] On the rigidly constructed base body 20, two lateral, raised sections 242, 243 are arranged engaging projections 240, 241 rigidly formed with the base body 20. These projections—viewed along a height direction H pointing along the closing direction X—are located above the bottom surface 230 and serve to establish a positive or non-positive connection between the connecting parts 2, 3 in the connected position. The engaging projections 240, 241 are spaced apart from one another along a transverse direction Q. The engaging 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 portion 300 of the second connecting part 3 is received in the connected position with an engagement portion 341 formed thereon between the engagement projections 240, 241 and the bottom surface 230 and is also supported on a front edge 305 on the support portion 233, so that the connecting parts 2, 3 are held together securely and reliably.
[0095] 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 against an engagement direction Y when the connecting parts 2, 3 are placed against one another along the closing direction X.
[0096] The recess 231 is laterally delimited by arcuate boundary walls 236, which together form a blocking section of the first connecting part 2 and are oriented perpendicular to a bottom of the recess 231 and also to the bottom surface 230. The boundary walls 236 extend in a circular arc around a central axis B of the recess 231, which is directed along a normal direction N of the bottom surface 230.
[0097] Between the boundary walls 236, a ramp 235 is formed, which is arranged rearward of the support section 233 at 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.
[0098] The floor surface 230 extends flat along a plane perpendicular to the normal direction N.
[0099] The second connecting part 3 is, as can be seen from the exploded views according to Fig. 2A , 2B and the separate views according to Fig. 5A, 5B and 6A-6C can be seen, firmly connected to a belt 4. The second connecting part 3 has a base body 30 on which the belt 4 is arranged fixedly and non-adjustably, in that the belt 4 lies in a belt webbing receptacle 32 formed between a base section 300 and a fastening section 301 and is thereby firmly arranged on the base body 30.
[0100] The base body 30 can, for example, be formed in one piece and integrally with the base section 300 and the fastening section 301 by plastic injection molding, wherein the belt 4 is overmolded in sections and is thus firmly and non-adjustably connected to the base body 30.
[0101] The base section 300 has a circular-cylindrical basic shape and forms a base surface 302 on a side facing the first connecting part 2 (when the connection is made), which base surface is flat and, when the second connecting part 3 is attached to the first connecting part 2, comes into contact with the bottom surface 230 in the receiving opening 23.
[0102] A blocking element 303, which is concentric with the circular-cylindrical base section 300 and has a circular cross-section, projects 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.
[0103] Within the blocking element 303, a fastening opening 35 is formed, which serves to receive the magnetic device 31, for example in the form of a permanent magnet of the second connecting part 3, and within which the magnetic device 31 is fastened.
[0104] The base section 300 forms an engagement device 34 of the second connecting part 3 with an engagement section 341, which serves to interact with the engagement projections 240, 241 of the engagement device 24 of the first connecting part 2 and, when the connection is established, dips below the engagement projections 240, 241, so that a positive or non-positive connection is established between the connecting parts 2, 3.
[0105] In the illustrated embodiment, the engagement portion 341 is formed by a circumferential edge of the base portion 300, which protrudes radially relative to the fastening portion 301 and thus forms an undercut, via which the engagement portion 341 can be brought into engagement with the engagement projections 240, 241 of the first connecting part 2, which also form undercuts, in order to connect the connecting parts 2, 3 to one another.
[0106] Based on Fig. 7A, 7B bis 11A-11D a connecting process of the connecting device 1 is shown.
[0107] The joining of the connecting parts 2, 3 generally occurs along the closing direction X, along which the magnetic devices 21, 31 interact in a magnetically attractive manner, thus magnetically attracting the connecting parts 2, 3 toward each other. The connecting parts 2, 3 can be manually brought closer together, whereby, from a certain proximity, the magnetic attraction force automatically draws the connecting parts 2, 3 into engagement, thus establishing the connection of the connecting device 1. Imprecise joining of the connecting parts 2, 3 is therefore sufficient, with the connection then being established largely automatically.
[0108] If the connecting parts 2, 3 are brought closer together, as can be seen from Fig. 7A und 7B As can be seen, the base section 300 of the base body 30 of the second connecting part 3 comes into contact with the engagement projections 240, 241 from above along the closing direction X, as can be seen from Fig. 8A, 8B Due to the inclined sliding slopes 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, wherein the base section 300 is provided with a Fig. 8B visible rear edge 304 can come into contact with the bottom surface 230 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 becoming caught prematurely.
[0109] If the base section 300 has slid on 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, in an engagement direction Y into engagement with the engagement projections 240, 241, as can be seen from Fig. 9A, 9B and 10A, 10B This movement along (approximately) the engagement direction Y occurs in a magnetically assisted manner, whereby a load force (introduced via the belt 4) can additionally assist the engagement.
[0110] When the engagement portion 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 in the transition from Fig. 10A, 10B towards Fig. 11A-11D is evident.
[0111] In the Fig. 11A-11E In the connected position shown, the blocking element 303 lies in the recess 231, and the base section 300 lies with the base surface 302 formed thereon flat against the bottom surface 230 within the receiving opening 23 of the first connecting part 2, as can be seen in particular from the sectional view according to Fig. 11B is evident.
[0112] In the connected position, the base section 300 faces the support section 233 with a (front) edge section 305 and bears against the support section 233 in a supporting manner. If a force is introduced into the second connecting part 3 via the belt 4, this force is absorbed and dissipated by the supporting contact of the base section 300 with the support section 233.
[0113] How this Fig. 11C und 11D As can be seen, the support section 233 is curved in an arc around the closing direction X, corresponding to the curvature of the circular cylindrical base section 300, so that there is a contact along an arc-shaped support line or surface between the edge section 305 on the base section 300 and the support section 233.
[0114] The support section 233 is arranged with a central section, viewed along the transverse direction Q, between the engagement projections 240, 241 and is spaced apart from the engagement projections 240, 241 at the central section along the engagement direction Y. The support section 233 extends in the cross-sectional plane according to Fig. 11D arched to below the engagement projections 240, 241 and beyond, so that a planar support for the base section 300 is created centrally between the engagement projections 240, 241 and also directly in the area of the engagement projections 240, 241.
[0115] In the connected position, the belt 4 is arranged on the connecting part 3 approximately at the height of the engagement projections 240, 241 on the connecting part 2 or below the engagement projections 240, 241. This ensures that belt forces introduced via the belt 4 cannot tilt the connecting part 3 in the receiving opening 23 or can only generate a slight tilting moment, wherein the engagement projections 240, 241 secure the position of the connecting part 3 on the connecting part 2, in particular along the height direction H.
[0116] In the connected position and when loads are applied between the connecting parts 2, 3, the belt 4 lies between the raised sections 242, 243 and is thus arranged between the engagement projections 240, 241, so that the engagement projections 240, 241 create a support symmetrical to the belt 4 when a force is introduced via the belt 4.
[0117] In the connected position, the magnetic devices 21, 31 interact in a magnetically attractive manner and thus hold the connecting parts 2, 3 in the connected position.
[0118] Due to the engagement of the blocking element 303 in the recess 231, a tangential displacement of the connecting parts 2, 3 relative to one another is also blocked counter to the engagement direction Y. In the connected position, the blocking element 303 lies in the recess 231 such that the blocking element 303 is received between the boundary walls 236 forming the blocking section and is in blocking contact with the arcuate boundary walls 236, so that the blocking element 303 cannot be moved counter to the engagement direction Y relative to the boundary walls 236.
[0119] 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 be moved in the connected position along a circumferential direction U (see Fig. 1 ) can be rotated by any angle about a rotation axis R within the receiving opening 23 of the connecting part 2, while maintaining the connecting engagement between the connecting parts 2, 3 and also the blocking of the blocking element 303 in the recess 231.
[0120] This rotatability also allows the connecting parts 2, 3 to be attached to one another in any rotational position, whereby when loaded via the belt 4, the connecting parts 2, 3 align themselves with one another such that the belt 4 lies between the engagement projections 240, 241 and thus the connecting part 3 is supported symmetrically on the connecting part 2. Due to the rotatability, the connecting parts 2, 3 can be attached to one another in a positionally tolerant manner, which makes establishing the connection simple and convenient.
[0121] How this Fig. 10A-10C As can be seen, the base section 300, with a front edge section 305, slides beneath the engagement projections 240, 241 into the insertion opening 232, which is recessed both relative to the bottom surface 230 and to the recess 231. By inserting the edge section 305 into the insertion 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. Furthermore, 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.
[0122] In the connected position, the front edge section 305 of the base section 300 then rests on a form-fitting section in the form of a step 234 formed between the immersion opening 232 and the support section 233 and located at the level of the bottom surface 230, as can be seen in particular from Fig. 11B can be seen. By placing the base section 230 on the steps 234, the connecting part 3 is additionally supported against tilting relative to the connecting part 2.
[0123] Alternatively, the form-fitting section can also be formed, for example, by a notch or the like on the support section 233, into which the base section 300 engages with the edge section 305 and is thereby supported on the support section 233 against tilting, which is accompanied by a movement of the edge section 305 on the support section 233 downwards in the closing direction X.
[0124] The form-fitting section in the form of step 234 ensures that the connected position is Fig. 11A bis 11E in particular, counteracts tilting when a load is applied to the belt 4. Thus, the second connecting part 3 with its base body 30 in the connected position rests with a first area 300A, formed by the (with respect to the engagement direction Y) rear section and the blocking element 303, on the bottom surface 230 of the base body 20 of the first connecting part 2 and in the recess 231 (see Fig. 11E ). In a second region 300B, which adjoins the engagement direction Y and is formed by the section above the insertion opening 232, the second base body 30 of the second connecting part 3, in contrast, does not rest against the first base body 20 of the first connecting part 2. With a third region 300C, which adjoins the second region 300B in the engagement direction Y and is formed by the front edge section 305 of the base section 300, the second base body 30 rests on the step 234, so that in the connected position, a support in the manner of a two-point support is created, with a free space created between them in the region of the insertion opening 232.
[0125] In the loaded position, the base section 300 is loaded with the front edge section 305 against the support section 233 and thus held in a self-reinforcing manner in contact with the step 234.
[0126] If the connecting parts 2, 3 are to be separated from each other, the movement sequence runs according to Fig. 7A, 7B bis 11A-11D In particular, to separate the connecting parts 2, 3, a user can engage an actuating portion in the form of a tab 40 (formed by a projecting portion of the strap 4) on a rear side of the connecting part 3 facing away from the engagement projections 240, 241, thereby lifting the connecting part 3 at its rear end from the base surface 230 and thus removing the connecting part 3 from the connected position according to Fig. 11A-11D tilt towards the connecting part 2 in such a way that the base section 300 with the front edge section 305 slides off the step 234 and the blocking element 303 is lifted out of the recess 231, as can be seen from Fig. 10A und 10B is visible. In this way, the blocking counter to the engagement direction Y between the connecting parts 2, 3 is lifted, so that the connecting part 3 can be pulled out of engagement from the connecting part 2 counter to the engagement direction Y and the connecting parts 2, 3 can thus be released from one another.
[0127] The tilting takes place in a tilting plane that is perpendicular to the base surface 230, namely spanned by the closing direction X and the engagement direction Y. The tilting takes place approximately around a tilting axis K (see Fig. 10A und 10B ) such that the connecting part 3 executes a pivoting movement in the tilting plane perpendicular to the tilting axis K and thus the blocking element 303 is lifted out of the recess 231, so that the connecting parts 2, 3 can be moved towards each other opposite to the engagement direction Y and thus separated from each other.
[0128] If, in particular when the connecting device 1 is not under load, the connection of the connecting parts 2, 3 is to be released, the connecting parts 2, 3 are tilted relative to one another and in particular also moved relative to one another opposite to the engagement direction Y, so that the front edge section 305 of the base section 300 (forming the third region 300C) slides off the step 234 and dips into the region of the insertion opening 232, as can be seen from Fig. 10B The form-fitting section created by the step 234 therefore no longer counteracts tilting, so that the connecting parts 2, 3 can be separated from one another conveniently and easily via the actuating section 40 when tilting.
[0129] Fig. 12A bis 12F show the connecting device 1 in a rotated position of the second connecting part 3 relative to the first connecting part 2. The second connecting part 3 can be attached to the first connecting part 2 in any (arbitrary) rotated position, and in any rotational position, the engagement portion 341 of the second connecting part 3 can be engaged with the engagement projections 240, 241 of the first connecting part 2. In the connected position, the second connecting part 3 is rotatable relative to the first connecting part 2 along a circumferential direction U about the rotation axis R while maintaining the engagement of the engagement portion 341 with the engagement projections 240, 241 and with engagement of the blocking element 303 in the recess 231.
[0130] Under load, when in the connected position of the connecting device 1 belt forces act between the belts 4, 5, the belt 4 lies between the engagement projections 240, 241, as can be seen from Fig. 1 can be seen. The engagement projections 240, 241 are in this case 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).
[0131] If, on the other hand, the second connecting part 3 is, as can be seen Fig. 12A bis 12F visible, twisted along the circumferential direction U about the rotation axis R to the first connecting part 2, the belt 4 can extend over one of the engagement projections 240, 241, with flexible, pliable deformation of the belt 4, as can be seen in particular from Fig. 12B and 12Dis visible. During rotation, the belt 4 slides (depending on the direction of rotation) onto one of the engagement projections 240, 241 and is thereby deformed, so that the belt 4 can be moved over the respective engagement projection 240, 241.
[0132] How this Fig. 1 for example in conjunction with Fig. 6C As can be seen, the belt 4 emerges from the fastening section 301 above the base section 300 at an exit line 306, which is curved according to the cylindrical shape of the fastening section 301. Beyond the exit line 306, i.e. outside the fastening section 301, the belt 4 is not connected to the base section 300 in the region of the protruding edge section forming the engagement section 341, but can be freely moved relative to the base section 300 and, in particular, lifted off the base section 300, which enables the deformation of the belt 4 to slide onto the engagement projection 240, 241 when the connecting part 3 is rotated relative to the connecting part 2 in a smooth manner.
[0133] The exit line 306 is offset radially inward relative to the front edge portion 305 of the base portion 300 and thus radially spaced from the edge portion 305. The belt 4 thus exits the fastening portion 301 along a line offset relative to the edge portion 305.
[0134] From the position according to Fig. 12A bis 12F The connecting part 3 can also be rotated further. In principle, the connecting part 3 can be rotated by any angle relative to the connecting part 2.
[0135] Under load between the belts 4, 5, the connecting parts 2, 3 move automatically back to the position according to Fig. 1 .
[0136] The connection or detachment of the connecting part 3 to or from the connecting part 2 is also generally possible in any rotational position.
[0137] In the embodiment according to Fig. 1 bis 12A-12F The connecting device 1 implements a strap fastener, via which straps can be connected to one another. In the connected position, a load direction determined by the straps is directed essentially along the engagement direction Y.
[0138] In another, in Fig. 13A, 13B bis 20A-20D In the illustrated embodiment, the connecting device 1 is designed as an object fastening device and serves to fasten an object to an associated assembly. The object can, for example, be arranged on a (second) connecting part 3 or integrated into the connecting part 3. In this way, for example, an electrical or electronic device, for example a communications device, a light, or the like, can be arranged on an associated assembly, for example a helmet or other sports equipment.
[0139] In the illustrated embodiment, the (second) connecting part 3 is rotationally symmetrical and forms a base section 300 arranged on a base body 30, which is circularly cylindrical in shape, as can be seen from Fig. 13A, 13B and 14A-14C can be seen. On an underside of the base portion 300, a base surface 302 is formed, from which a blocking element 303 protrudes, which is circular in cross-section and concentric with the base surface 302.
[0140] A fastening opening 35 for receiving a magnetic device 31 is formed on a housing section raised relative to the base section 300.
[0141] The (second) connecting part 3 according to Fig. 13A, 13B und 14A-14C can be sent to a Fig. 15A, 15B and 16A-16C shown (first) connecting part 2 can be attached, which has a base body 20 on which a bottom surface 230 is formed, which extends flatly and evenly on a side of the base body 20 facing the connecting part 3 (when the connecting parts 2, 3 are attached to one another) and with which the base surface 302 comes into flat contact with the base section 300 of the connecting part 3 when the connecting parts 2, 3 are connected to one another.
[0142] As explained with reference to the previously described embodiment, a recess 231 is formed in the bottom surface 230, which serves to receive the blocking element 303 of the connecting part 3. Adjoining the bottom surface 230 is also an insertion opening 232, which is located between the bottom surface 230 and a support section 233 formed in a front region of the base body 20.
[0143] On raised portions 242, 243, engagement projections 240, 241 are arranged, which are rigidly formed with the base body 20 and are arranged above the bottom surface 230 when viewed along a height direction H. In the connected position of the connecting parts 2, 3, an engagement portion 341, which is formed by a circumferential, radially projecting edge of the base portion 300 of the connecting part 3, is received between the bottom surface 230 and the engagement projections 240, 241.
[0144] To the rear of the bottom surface 230, the base body 20 forms a fastening opening 25 in which a magnetic device 21 is arranged for magnetic interaction with the magnetic device 31 of the connecting part 3.
[0145] The connection process of the connecting parts 2, 3, shown in Fig. 17A, 17B bis 20A-20D , proceeds as described above for the embodiment according to Fig. 1 bis 12A-12F has been described.
[0146] For example, the connecting parts 2, 3 are brought closer together along a closing direction X, which is directed along the height direction H, as can be seen from Fig. 17A und 17B The magnetic devices 21, 31 interact in a magnetically attractive manner and pull the connecting parts 2, 3 towards each other along the closing direction X, so that the connecting part 3 runs onto the engagement projections 240, 241 and slides off at the rear ends 246, 247 of the engagement projections 240, 241, as can be seen from Fig. 18A und 18B can be seen. The base section 300 comes into contact with the bottom surface 230 with a rear edge section 304, so that the connecting part 3 slides along a sliding direction A towards the connecting part 2 and the base section 300 is thus moved on the engagement projections 240, 241 until the base section 300 can pass the engagement projections 240, 241 and the connecting part 3 is thus in the position according to Fig. 19A, 19B to the connecting part 2 and the blocking section is held above the recess 231 so that the connecting parts 2, 3 do not hook together prematurely.
[0147] If the base section 300 has been moved past the engagement projections 240, 241 along the closing direction X, the engagement section 341 formed on the base section 300 slides in an engagement direction Y into engagement with the (rigid) engagement projections 240, 241, as in the transition from Fig. 19A, 19B towards Fig. 20A, 20B The blocking element 303 slides into the recess 231, magnetically supported by the magnetic attraction of the magnetic devices 21, 31.
[0148] In the connected position according to Fig. 20A-20D The base section 300 rests with the base surface 302 flat against the bottom surface 230 of the connecting part 2. The blocking element 303 rests in the recess 231. A front edge section 305 of the base section 300 is in contact with the support section 233, wherein the front edge section 305 also rests on a step 234 between the immersion opening 232 and the support section 233, as can be seen from Fig. 19B can be seen. Because the engagement portion 341 formed on the base portion 300 engages with the engagement projections 240, 241, the connecting part 3 is held positively or non-positively on the connecting part 2, wherein the position of the connecting parts 2, 3 is secured by the magnetic devices 21, 31 and, moreover, disengagement counter to the engagement direction Y is blocked by the blocking element 303.
[0149] Due to the rotational symmetry of the connecting part 3, the connecting part 3 can be rotated on the connecting part 2 in the connected position.
[0150] Due to the rotational symmetry, the connecting part 3 can also be arranged in any rotational position on the connecting part 2, which enables a simple, convenient connection of the connecting parts 2, 3 to one another.
[0151] To release the connection 2, 3, the connecting part 3 can be tilted in a tilting plane spanned by the closing direction X and the engagement direction Y to the connecting part 2, with the engagement section 341 formed by the edge of the base section 300 being immersed in the immersion opening 232, analogously to Fig. 19B The blocking of the blocking element 303 in the recess 231 is thus released, so that the connecting parts 2, 3 can be removed from each other.
[0152] In another, in Fig. 21 bis 30A-30D In the illustrated embodiment in the form of a belt strap fastener, a first connecting part 2 has a base body 20 on which a receiving opening 23 is formed. A second connecting part 3 can be attached to the first connecting part 2 by inserting a pin element 340 formed on a base section 300 of a base body 30 of the second connecting part 3 into the receiving opening 23 and engaging it via a circumferential engagement section 341 with an arcuate engagement projection 240 on a wall section of the receiving opening 23 of the first connecting part 2.
[0153] In the illustrated embodiment, a strap 4 is firmly connected to the base body 30 of the connecting part 3 via a fastening section 301 formed on the base section 300. The 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.
[0154] The pin element 340 protrudes from the base surface 302. The pin element 340 has a mushroom shape and carries the engagement portion 341 extending circumferentially around the closing direction X and implementing an engagement device 34. In the illustrated embodiment, the engagement portion 341 is thus spatially separated from the base portion 300 in that the engagement portion 341 is spaced apart from the base portion 300 along the closing direction X.
[0155] In the illustrated embodiment, 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 connecting part 3 is placed on the connecting part 2, so that the connecting part 3 is displaced opposite to the engagement direction Y to the connector part 2 and the engagement section 341 is moved past the engagement projection 240 until the engagement section 341 can be brought into engagement with the engagement section 240 in the engagement direction Y.
[0156] The connecting parts 2, 3 each have a magnetic device 21, 31 (see Fig. 22A, 22B ), which are magnetically attractive to each other along the closing direction X and thus magnetically support the positioning of the connecting parts 2, 3 in the closing direction X.
[0157] In the illustrated embodiment, the disc-shaped base portion 300 projects radially beyond the engagement portion 341 on the pin element 340, as can be seen from Fig. 25A, 25B and 26A-26B is evident.
[0158] When attaching the connecting parts 2, 3 to each other, shown in the sequence according to Fig. 27A, 27B bis 30A-30D , the connecting part 3 is brought closer to the connecting part 2 in the closing direction X, wherein the connecting part 3 can perform a wobbling movement such that first the engagement section 341 with the inclined surface 342 formed thereon comes into contact with the engagement projection 240 in the receiving opening 23, as can be seen from Fig. 28B can be seen, and is moved past the engagement projection 240 by sliding, as is the case in the transition from Fig. 28A, 28B towards Fig. 29A, 29B is evident.
[0159] If the engagement portion 341 has been moved past the engagement projection 240, the engagement portion 341 engages with the engagement projection 240 in the engagement direction Y due to magnetic attraction between the magnet devices 21, 31, so that the connecting parts 2, 3 are in the connected position according to Fig. 30A-30D get there.
[0160] In the connected position, the engagement portion 341 on the pin element 340 engages 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 portion 341 faces a blocking portion 238 in the form of a projection element projecting into the receiving opening 23 in the engagement direction Y. The blocking portion 238 thus 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 portion 341 and the engagement projection 240 is blocked.
[0161] In the connected position, the base portion is in contact with a peripheral outer edge portion 305 with a support portion 233 which is positioned in front of the engagement projection 240 in the engagement direction Y, as shown in Fig. 30B can be seen. Thus, via the support section 233, support is created on the base section 300 in the engagement direction Y, so that when a load is applied between the connecting parts 2, 3, forces along the load direction corresponding to the engagement direction Y are absorbed and dissipated at the support section 233.
[0162] As this also shows Fig. 30B As can be seen, in the region of the support section 233, a form-fitting section 234 in the form of a step is formed, on which the base section 300 rests with the edge section 305 in the closing direction X. The step counteracts a tilting of the base section 300 and thus of the connecting part 3 relative to the connecting part 2 in order to prevent an unintentional release of the connecting parts 2, 3 under load.
[0163] How this Fig. 30B in conjunction with Fig. 29B As can be seen, the step 234 is adjoined by an immersion opening 232, which serves to provide a free space into which the base section 300 can immerse itself when tilted relative to the connecting part 2, 3, as can be seen from Fig. 29B is evident.
[0164] If the connecting parts 2, 3 are to be separated from each other, a user can pull on an actuating section in the form of a tab 40 on the back of the connecting part 3 and thus lift the pin element 340 out of the receiving opening 23 on a side facing away from the engagement projection 240, as can be seen from Fig. 29B can be seen. The base section 300 dips into the insertion opening 232 with a front region facing the support section 233, which facilitates the tilting of the connecting part 3 relative to the connecting part 2 for releasing the connecting parts 2, 3 from one another.
[0165] In the connected position, the support on the step 234 is used, analogous to the initial example according to Fig. 1 bis 12A-12F , counteracts tilting under load. Via the insertion opening 232, a free space is created in an area adjacent to the step 234 opposite to the engagement direction Y, into which the base section 300 can insert with its circumferential edge section when the connecting parts 2, 3 are tilted relative to one another to separate the connection.
[0166] In the Fig. 21 bis 30A-30D In the embodiment shown, the engagement portion 341 is not formed on the disc-shaped base portion 300, but on the pin element 340 protruding from the base portion 300 along the closing direction X, so that the engagement portion 341 is spaced apart from the base portion 300 along the closing direction X and, in addition, the circumferential edge portion 305 of the base portion 300 is arranged radially outside the engagement portion 341.
[0167] The engagement section 341 is thus spatially separated from the base section 300. Furthermore, the establishment of a positive or force-fit connection via the engagement section 341 is functionally separate from the support of the base section 300 on the support section 233 and the positive-fit section 234. This can, for example, promote the support of the base section 300 for load absorption on the support section 233 and also for counteracting tilting via the positive-fit section 234, in that the base section 300 can provide a comparatively large lever arm for support compared to the engagement section 341.
[0168] In the embodiment according to Fig. 21 bis 30A-30D the support section 233 is rigidly formed on the base body 20 of the connecting part 2 by a surface section which extends perpendicular to a direction radial to the closing direction X and is curved in an arc around the closing direction X, as can be seen from Fig. 30B in conjunction with Fig. 24A can be seen. Likewise, the form-fitting section 234 is curved in the shape of the step and thus forms a support for the edge section 305 of the base section 300.
[0169] In a modified, in Fig. 31A-31C In the exemplary embodiment shown, an arcuate support section 233 extending obliquely to the closing direction X jointly fulfills the function of the support section 233 and the form-fitting section 234 of the exemplary embodiment according to Fig. 21 bis 30A-30D . The obliquely extending support section 233 of the embodiment according to Fig. 31A-31C forms a support for an oblique edge section 305 of the base section 300 of the connecting part 3, so that via the support section 233 both a support in the engagement direction Y and a support against tilting, i.e. against a movement of the base section 300 in the front area in the closing direction X, is created.
[0170] Otherwise, the embodiment is as per Fig. 31A-31C identical to the embodiment according to Fig. 21 bis 30A-30D , so reference should also be made to the previous explanations.
[0171] Fig. 32-58 show exemplary uses of a connecting device 1, as described in the embodiments according to Fig. 1-31 has been described.
[0172] A connecting device 1 can be used, for example, on a bag or a backpack, as in Fig. 32-39 The connecting device 1 can be used to connect belt ends ( Fig. 32 ,35 , 36 and 39 ), for connecting straps to a bag body ( Fig. 33, 34 and 38 ) or for closing a lid of a bag or backpack or for attaching an object to the bag or backpack ( Fig. 37 ) serve.
[0173] The connecting device 1 can be used as a closure for a shoe ( Fig. 40 and 41 ), as a closure for pockets on a textile item, for example a jacket or vest ( Fig. 42 ), or as a closure for a medical bandage ( Fig. 43-45 ) serve.
[0174] The connecting device 1 can be used as a closure for a belly bag ( Fig. 46 ) or for a tool belt ( Fig. 47 ) serve.
[0175] 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. 48 ).
[0176] The connecting device 1 can serve as a closure for a strap on a musical instrument, for example a guitar ( Fig. 49 ).
[0177] The connecting device 1 can be used, for example, to attach a strap to a bicycle, for example to a luggage carrier or a basket on a bicycle ( Fig. 50 ).
[0178] The connecting device 1 can also be used as a closure for a helmet ( Fig. 51 ) serve.
[0179] The connecting device 1 can provide a belt closure for lacing an object, for example a mat ( Fig. 52 ).
[0180] The connecting device 1 can also provide a closure for a belt system for stowing luggage in a vehicle, for example a car ( Fig. 53 ).
[0181] 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. 54 ).
[0182] The connecting device 1 can provide a holder for objects on a shelf, for example for key rings on a key shelf ( Fig. 55 ).

[0184] A connecting device 1 can be used as a closure for a wristwatch ( Fig. 57 ) or a bracelet ( Fig. 58 ) serve.
[0185] In all of the above-mentioned applications, the rotatability of the connecting parts 2, 3 solves important aspects of the respective application requirements. Conventional push-in fasteners, which are often used for such applications, are not rotatable.
[0186] Other applications are conceivable and possible.
[0187] The idea underlying the invention is not limited to the embodiments shown, but can also be implemented in other ways.
[0188] In particular, a connecting device of the type described can be used not only as a strap fastener for connecting base ends or as an object fastening device. A connecting device of the type described can be used to connect completely any assemblies to one another. Bezugszeichenliste
