Description

Technical Field

[0001] The invention relates to a connecting device for releasably connecting two components. Background Art

[0002] The connection device comprises: a first connection part, the first connection part having a coupling opening and a first magnetic element; and a second connection part, the second connection part having a coupling section and a second magnetic element. The first connection part and the second connection part can be connected to each other in such a way that the coupling section of the second connection part can be coupled with the coupling opening of the first connection part along a coupling direction, wherein the first magnetic element and the second magnetic element act together magnetically when the first connection part and the second connection part are coupled.

[0003] Such a connecting device can be used, for example, as a closure for clothing. For closing, the connecting parts are brought into contact with each other so that the engagement section of the first connecting part engages with the engagement opening of the second connecting part in the engagement direction, wherein the bringing of the connecting parts into contact with each other is supported magnetically by magnetic elements arranged on the connecting parts.

[0004] In such a connection device, there is usually a demand for simple operation, in particular for opening the connection device. It may be desirable here that an emergency opening can be achieved in the case of an excessive load, so that, for example, the danger caused by improper use is avoided in the case of clothing. Summary of the invention

[0005] The object of the present invention is to provide a connecting device which provides an emergency opening function.

[0006] This object is achieved by a connecting device having the features of the present application.

[0007] Therefore, the joining opening and / or the joining section has a shape that tapers in the joining direction in a cross-sectional plane spanned by the joining direction and a transverse direction extending transversely to the joining direction.

[0008] In particular, the first connecting part can have a first contact surface which at least partially delimits the joining opening, and the second connecting part can have a second contact surface which at least partially delimits the joining section, wherein the first contact surface and the second contact surface face one another in a connection position in which the joining section of the second connecting part engages with the joining opening of the first connecting part. The tapered shape at the joining opening and / or the joining section can be achieved in that at least one contact surface is curved or extends obliquely with respect to the joining direction.

[0009] By configuring the engagement opening and / or the engagement section in a tapered shape along the engagement direction, it is possible to achieve that, under loads transverse to the engagement direction, the connection device can be caused to open. Thus, under loads transverse to the engagement direction that exceed the release force defined by the dimensions of the magnetic element and the design of the engagement opening and the engagement section, the engagement section strikes against the contact surface formed at the engagement opening, so that in the sense of a force deflection, the connection parts are caused to separate from each other in the opposite direction of the engagement. In particular, the contact surfaces at the engagement section and the engagement opening can strike against each other under transverse loads, so that the connection parts are separated from each other in the opposite direction of the engagement, whereby the magnetic force between the connection parts is weakened and the connection parts are thus disengaged from each other.

[0010] At least one of the contact surfaces can be arranged obliquely to the joining direction and can extend, for example, linearly in a cross-sectional plane developed by the joining direction and the transverse direction. Alternatively, the corresponding contact surface can also extend in a curved manner in the cross-sectional plane, so that the joining opening and / or the joining section, for example, has a spherical shape.

[0011] In one configuration, the first contact surface and the second contact surface are each curved or extend at an oblique angle to the joining direction.

[0012] However, it is also conceivable that the first contact surface and the second contact surface are shaped differently. For example, in one configuration, only one of the contact surfaces extends in a curved manner or obliquely relative to the joining direction, while the other contact surface extends along the joining direction.

[0013] The first contact surface can extend circumferentially around the joining opening of the first connection part. The first contact surface thus forms a circumferential surface that surrounds the joining opening around the joining direction. Additionally or alternatively, the second contact surface can extend circumferentially around the joining section of the second connection part, so that the second contact surface forms a side surface that surrounds the joining section around the joining direction. This can result in that in different load directions transverse to the joining direction, for example in any plane extending transverse to the joining direction, emergency opening can be achieved by the contact surfaces colliding with each other.

[0014] The first contact surface of the joint opening and the second contact surface of the joint section can have the same (but complementary) shape, in that the first contact surface and the second contact surface are curved in the same way or extend at the same angle of inclination relative to the joint direction. Under transverse loads, the contact surfaces can collide with each other, so that when a defined release force is exceeded, the connecting parts are separated from each other opposite to the joint direction.

[0015] In one embodiment, at least one structural element is provided at at least one of the contact surfaces, the structural element having at least one surface section that deviates from the curved or inclined extension direction of the contact surface. For example, a structure of the type of projections, teeth, waves or steps can be provided at one contact surface or at both contact surfaces, wherein the corresponding contact surface can be designed, for example, completely in the form of waves or steps or such structural elements can be provided only at subsections of the contact surface. By providing the structural element at one or both contact surfaces, the friction between the contact surfaces under transverse load can be set, so that the release force that must be exceeded in order to separate the connecting parts from each other can be set in a defined manner.

[0016] Additionally or alternatively, the friction between the contact surfaces can be set by the material and its surface properties (structure), for example the roughness.

[0017] For example, the first contact surface and / or the second contact surface can have at least one step and thus be completely or partially stepped. Each step can be formed, for example, in a cross-sectional plane extending through the joining direction and the transverse direction by an end face extending along the joining direction or obliquely to the joining direction and a step extending transversely to or obliquely to the joining direction, wherein in the case of a stepped design of the corresponding contact surface, one step is connected to the end face and one end face is connected to the step.

[0018] The transition between the end face and the platform face can be rounded.

[0019] It is also conceivable to orient the end faces of the contact surfaces in a stepped design in such a way that an undercut results, through which the contact surfaces rest against one another under transverse loads.

[0020] In one embodiment, the joining opening is bounded by the bottom. The first magnetic element of the first connecting part can be arranged in the region of the bottom, for example in that the first magnetic element is accommodated in the center of the joining opening on the housing part forming the bottom. The first contact surface of the first connecting part, viewed opposite to the joining direction, can extend essentially above the bottom, so that the first magnetic element is flush with the bottom or embedded in the bottom and the contact surface protrudes from the bottom opposite to the joining direction.

[0021] In one embodiment, a protruding section opposite to the joining direction is arranged within the joining opening of the first connecting part, which engages into a receiving opening at the joining section of the second connecting part when the joining section engages with the joining opening. The protruding section can, for example, protrude from the bottom of the joining opening opposite to the joining direction and engage into an associated receiving opening at the joining section of the second connecting part when the connecting parts are connected to one another. By means of such a protruding section, the release force that must be exceeded by the transverse load for the purpose of emergency opening can be additionally influenced in that the transverse support of the connecting parts in the connected position is increased.

[0022] On the protruding section and the receiving opening, collision surfaces can be formed which collide with each other under transverse loads, so that the connecting parts can automatically release each other when the transverse load exceeds the release force, in order to provide an emergency opening function in this way.

[0023] In one embodiment, the joining opening and / or the joining section are rounded or polygonal in a cross section transverse to the joining direction. For example, the joining opening and the joining section can have a circular shape and thus be rotationally symmetrical with respect to the joining direction. Alternatively, the joining opening and the joining section can be triangular, quadrilateral, pentagonal or hexagonal, respectively, wherein the joining opening and the joining section preferably have a regular shape with identical edges in a cross section transverse to the joining direction (in a polygonal embodiment).

[0024] In one design, the first connecting part has another engaging section and / or the second connecting part has another engaging opening. The first connecting part and the second connecting part can therefore be connected to another connecting part in a stacked manner, in which the other connecting part is connected to the first connecting part by engaging another engaging section of the first connecting part into the engaging opening of the other connecting part, or the other connecting part is connected to the second connecting part by engaging into another engaging opening of the second connecting part.

[0025] Preferably, the first and second connecting parts are designed as common components at least in the area of ​​the joining section and the joining opening, so that each connecting part can be connected to the other connecting parts in any manner, in that the connecting parts can be arranged below or above the other connecting parts.

[0026] In one embodiment, the first connection part has two first housing parts, which accommodate the first magnetic element between them. The housing parts can be locked to each other, for example, to form the first connection part, wherein a receiving opening is formed between the housing parts for accommodating the first magnetic element, so that in the installed position the first magnetic element is fixed relative to the housing parts. Between the housing parts, an associated first component, for example a textile fabric, can be accommodated, so that the first connection part can be connected to the component via the housing parts.

[0027] Additionally or alternatively, the second connecting part can have two second housing parts, which accommodate the second magnetic element between them. The second housing parts can be locked to each other and together form a receiving opening for the second magnetic element. An associated second component, such as a textile fabric, can be accommodated between the second housing parts, so that the first connecting part can be connected to the component via the housing parts.

[0028] The housing parts can be connected to each other in such a way that they accommodate the respectively associated magnetic element in a sealing manner between them. Via the locking section, for example, a connection can be achieved which surrounds the magnetic element in a moisture-tight manner and thus protects against contamination and moisture.

[0029] Alternatively, it is also conceivable that the first connecting part and / or the second connecting part are formed in one piece, wherein additional fastening elements can be provided in the region of edge sections of the first connecting part or the second connecting part for fastening the connecting part to the respectively associated component.

[0030] In one embodiment, the first connecting part has a first edge section extending around the joint opening for connecting to the first component. Additionally or alternatively, the second connecting part can have a second edge section extending around the joint section for connecting to the second component. Via such an edge section, the respective connecting part can be fixed to the associated component, for example mechanically or chemically, for example by sewing, gluing, welding or riveting.

[0031] If the respective connecting part is composed of two housing parts, the two housing parts can each have an edge section, wherein the associated component can be accommodated between the edge sections and connected to the connecting part via the two edge sections, for example by gluing or riveting.

[0032] In one embodiment, the first connecting part has a first joining section for connecting to the first component, and the second connecting part has a second joining section for connecting to the second component. The first joining section and the second joining section can extend along a common plane extending transversely to the joining direction. This can result in that when the components are loaded relative to each other transversely to the joining direction, the load forces act between the connecting parts in a common plane, so that under transverse loads, a defined force introduction and a defined release are achieved by the collision of the joining sections and the joining opening.

[0033] The first magnetic element and the second magnetic element can be respectively formed by a permanent magnet or a device of multiple permanent magnets, for example. When the connecting parts are placed close to each other, the first magnetic element and the second magnetic element face each other by means of one pole or multiple non-same poles, so that a magnetic attraction is generated between the magnetic elements, thereby magnetically supporting the connection parts to be placed close to each other.

[0034] However, it is also conceivable that one of the magnetic elements at one of the connecting parts is made as a permanent magnet or by an arrangement of multiple permanent magnets, and the magnetic element at the other connecting part is made as a magnetic armature, for example a magnetic armature made of ferromagnetic material, which cooperates with the permanent magnet or the arrangement of permanent magnets in a magnetically attractive manner.

[0035] In one design, the magnetic element holds the connecting parts against each other in the connected position. The connecting parts are held against each other, for example, only via the magnetic element, without any additional mechanical locking between the connecting parts.

[0036] A connection device of the type described can be used in many ways. In particular, the connection device can be used in all articles in which an emergency triggering is desired under a transverse load transverse to the joining direction.

[0037] The connection device can be used, for example, in clothing, especially for children or the elderly or disabled. For example, a connection device of the type described can be used in double-sided clothing, such as double-sided jackets, which can be turned inside out.

[0038] The type of connection device described can typically be used for rope, fabric or belt applications that present a risk of choking and therefore require an emergency opening, such as whistles, bibs, safety belts and restraint harnesses, collars, seat belt systems, helmets, hoods and headbands for clothing, fastening systems for wall panels, organizational systems, workwear and restraint systems, accessory and attachment fastening, neckbands and scarves, cable and belt organization, sleeping bags, shoes, bags and backpacks, etc.

[0039] A plurality of connecting devices can be used in combination in this case in order to enable, for example, a closure along a closure line in a garment, such as a jacket. BRIEF DESCRIPTION OF THE DRAWINGS

[0116] Figures 1A to 1D A first embodiment of a connection device 1 is shown, which has a first connection part 2 and a second connection part 3. Figures 1A to 1D The connecting parts 2 , 3 shown in the connected position in FIG. 1 can be brought against one another along a joining direction E and can be released from one another in a release direction L opposite to the joining direction E.

[0117] Each connecting part 2, 3 has a housing part 20, 30, which forms an edge section 200, 300, via which the respective connecting part 2, 3 can be connected to an associated component, such as a garment. The connecting parts 2, 3 can be designed rotationally symmetrically in the illustrated embodiment and can be manufactured as a universal component, so that the connecting parts 2, 3 can be arranged adjacent to each other in any order. In particular, the connecting part 3 can also be arranged below the connecting part 2 in the joining direction E.

[0118] In the exemplary embodiment shown, each connecting part 2 , 3 has a joining section 22 , 32 which projects in a pin-like manner from the edge section 200 , 300 in the direction of the joining direction E. A joining opening 23 , 33 is formed inside each joining section 22 , 32 .

[0119] exist Figure 1C The joining sections 22 , 32 and the joining openings 23 , 33 taper in the joining direction E, as viewed in a cross-sectional plane shown in FIG. 5 , which extends through the joining direction E and the transverse direction Q (corresponding to the radial direction).

[0120] In order to connect the connecting parts 2, 3 to each other, for example, the connecting part 3 with the connecting section 32 can be inserted into the connecting opening 23 of the connecting part 2, as shown in Figure 1A Combination Figure 1C and 1D In the connected position, the engagement section 32 of the connecting part 3 engages in the engagement opening 23 of the connecting part 2, such as, for example, from Figure 1C Visible in.

[0121] Each connecting part 2, 3 has a magnetic element 24, 34, which is arranged in the area of ​​the bottom 231, 331 of the joining opening 23, 33 of the respectively associated connecting part 2, 3. The magnetic elements 24, 34 act together magnetically when the connecting parts 2, 3 are arranged in the joining direction E, so that the arrangement of the connecting parts 2, 3 against each other is magnetically supported, and preferably automatically when the connecting parts 2, 3 are approached to each other.

[0122] In the connected position, the connecting parts 2, 3 are held magnetically against one another via the magnetic elements 24, 34. No additional locking is present here.

[0123] The magnetic elements 24, 34 can each be formed by a permanent magnet or by an arrangement of permanent magnets. Alternatively, one of the magnetic elements 24, 34 can be formed by a permanent magnet or an arrangement of permanent magnets, while the other magnetic element 34, 24 is formed by a magnetic armature, i.e. a passive element, which however magnetically cooperates with the permanent magnet or the arrangement of permanent magnets.

[0124] Since the connection sections 22, 32 and the connection openings 23, 33 of the connection parts 2, 3 taper in the connection direction E, an emergency opening of the connection device 1 can be achieved by the connection parts 2, 3. Therefore, the connection sections 22, 32 each form a contact surface 220, 320, which is formed by the conical side surface of the corresponding connection section 22, 32. Complementarily to the connection sections 22, 32, the connection openings 23, 33 are each bounded by a conical contact surface 230, 330. The contact surfaces 220, 230, 320, 330 here each extend circumferentially around the connection direction E and are rotationally symmetrical with respect to the connection direction E.

[0125] If the joint portion 3 is as in Figure 1C 3, the conical contact surface 320 of the engagement section 32 abuts against the complementary conical contact surface 230 of the engagement opening 23 of the connection part 2. If a load occurs in a radial transverse direction Q between the connection parts 2, 3, the conical shape of the contact surfaces 230, 320 causes the contact surfaces 230, 320 to collide with each other in the transverse direction Q so that the transverse force is converted into a force in a release direction L opposite to the engagement direction E, so that if the transverse load exceeds the release force predetermined by the size of the magnetic elements 24, 34 and also by the geometrical and frictional properties of the connection parts 2, 3, the connection sides 2, 3 automatically release from each other in the sense of emergency opening.

[0126] Since the connecting parts 2 , 3 are designed as common components, the connecting parts 2 , 3 can be placed next to each other in any order. Therefore, the connecting part 2 can also be inserted into the connection opening 33 of the connecting part 3 by means of the connection section 22 .

[0127] Due to the conical shape of the joining sections 22 , 32 and the joining openings 23 , 33 , a transverse load in any radial direction relative to the joining direction E brings about an emergency opening when a predefined release force is exceeded.

[0128] exist Figures 1A to 1D In the exemplary embodiment shown in , each connecting part 2 , 3 is assigned a single housing part 20 , 30 , in which the corresponding magnetic element 24 , 34 is accommodated.

[0129] exist Figures 1A to 1DIn the embodiment shown in FIG. 1 , the contact surfaces 220 , 230 , 320 , 330 are Figure 1C The cross-sectional planes shown in each case extend obliquely to the joining direction E and have the same inclination angle relative to the joining direction E, for example in the range between 5° and 80°, in particular in the range between 20° and 60°.

[0130] exist Figures 2A to 2E In the embodiments shown in Figures 4A-4D, the connecting parts 2, 3 of the connecting device 1 are formed by two shell parts 20, 21, 30, 31 respectively, which are locked to each other to form the corresponding connecting parts 2, 3 and respectively accommodate the magnetic elements 24, 34 therebetween.

[0131] Each connecting part 2, 3 has an upper housing part 20, 30 and a lower housing part 21, 31. In the installed position, the corresponding magnetic element 24, 34 is received between the housing parts 20, 21, 30, 31 and is held in a receiving opening 211, 311 of the lower housing part 21, 31.

[0132] The upper housing part 20 forms a joining opening 23 , 33 having a contact surface 230 , 330 and a bottom 231 , 331 .

[0133] On the side facing away from the engagement openings 23, 33, the housing parts 20, 30 have circumferential locking sections 201, 301 which engage in a locking manner with circumferential locking sections 212, 312 on the housing sections of the lower housing parts 21, 31 forming the receiving openings 211, 311, in order to connect the housing parts 20, 21, 30, 31 to one another, as for example from Figure 3C and 3D As can be seen in .

[0134] The lower housing parts 21 , 31 each form a joining section 22 , 32 which has a circumferential, conical contact surface 220 , 320 .

[0135] Each shell part 20, 21, 30, 31 forms an edge section 200, 210, 300, 310. Between the edge sections 200, 210, 300, 310 of the shell parts 20, 21, 30, 31 of each connecting part 2, 3, a component, such as a textile fabric of clothing, can be accommodated in order to connect the connecting parts 2, 3 in the described manner to the respectively associated component.

[0136] Regarding the connection and emergency opening functions for connecting parts 2, 3, according to Figures 2A to 2E Embodiments and methods according to 4A-4D Figures 1A to 1DThe embodiments are the same, so reference should be made to the above embodiments.

[0137] At the connection location ( Figures 3A to 3D ), the engaging section 32 of one connecting part 3 engages with the engaging opening 23 of the other connecting part 2, wherein under the lateral load caused by the collision of the contact surfaces 230, 320 with each other, a force deflection is caused along the loosening direction L, thereby being used to separate the connecting parts 2, 3 for emergency opening.

[0138] exist Figures 5A to 5D The embodiments shown in Figure 2A-2E 4A-4D are similar, but differ from the above-mentioned embodiments in that the contact surfaces 220, 230, 320, 330 are each formed in a stepped manner with a step 221, as can be seen in particular from the embodiment according to Figure 5D Each step 221 is formed by a vertical end face 222 and a horizontal terrace 223, wherein each contact surface 220, 230, 320, 330 extends as a whole obliquely to the joining direction E in such a way that it follows an extension direction extending obliquely to the joining direction E and has an average slope of the extension direction.

[0139] In the connected position, the contact surface 320 at the joining section 32 of the connecting part 3 is in contact with the contact surface 230 within the joining opening 23 of the other connecting part 2, as shown in FIG. Figure 5C and 5D By means of the stepped design of the contact surfaces 220, 230, 320, 330, the movability of the contact surfaces 220, 230, 320, 330 relative to one another under transverse loads can be set so that the release force required for emergency opening can be dimensioned.

[0140] As from Figures 6A to 6D As can be seen in , a stepped design can also be achieved here in that the end face 222 of the step 221 on the contact surface 220 , 230 , 320 , 330 extends obliquely to the joining direction E (for example at an angle of between 5° and 20°).

[0141] Alternatively, the end surface 222 is as shown in accordance with Figures 7A to 7D In the exemplary embodiment, undercuts may also be formed in order to make it more difficult or even prevent the contact surfaces 220, 230, 320, 330 from sliding onto each other.

[0142] Alternatively, the transition between the end face 222 of the step 221 and the terrace 223 may be rounded, as in Figures 8A to 8D As in the embodiment of .

[0143] The end face 222 of the step 221 can also be arranged obliquely in this rounded design, such as in Figures 9A to 9D or constitute an undercut, as in the embodiment according to Figures 10A to 10D As in the embodiment of .

[0144] The step 221 forms a structural element on the contact surfaces 220, 230, 320, 330, by means of which a tangential sliding movement of the contact surfaces 220, 230, 320, 330 relative to one another can be set. Such a structural element interrupts the generally inclined extension of the contact surfaces 220, 230, 320, 330. The structural element can extend circumferentially around the contact surfaces 220, 230, 320, 330, as in the step 221 of the above-described exemplary embodiment, but can also be limited in location to one or more circumferential sections.

[0145] Instead of the steps 221 , other structural elements may also be provided, for example in the form of projections, teeth, waves, ribs or the like.

[0146] exist Figures 11A to 11D In the embodiment shown in Figures 1A to 1D Compared to the embodiment of the present invention, a protruding section 232, 332 in the form of a truncated cone is formed in the region of the joining opening 23, 33 of each connecting part 2, 3, which protrudes opposite to the joining direction E and is bounded by a circumferential collision surface 233, 333. Complementarily, a receiving opening 224, 324 is formed on the joining section 22, 32 of each connecting part 2, 3, which is bounded by a circumferential collision surface 225, 325.

[0147] In the connected position, the engagement section 32 of one connecting part 3 engages in the engagement opening 23 of the other connecting part 2, such as from Fig. 11C In this case, the projection 232 engages in the region of the bottom 231 of the engagement opening 23 in the receiving opening 324 on the engagement section 32 , so that the lateral holding of the connecting parts 2 , 3 relative to one another is thereby improved.

[0148] Under lateral loading of the connecting parts 2, 3 relative to one another, the contact surfaces 230, 320 of the joining opening 23 and of the joining section 32 collide with one another, as described above according to Figures 1A to 1D Furthermore, the collision surfaces 233 , 325 of the protruding section 232 and the receiving opening 324 collide with each other, so that an emergency opening function is again obtained.

[0149] As in accordance with Figures 1A to 1D In the exemplary embodiment, the contact surfaces 220 , 230 , 320 , 330 extend obliquely to the joining direction E, so that a conical, tapering shape is obtained at the joining sections 22 , 32 and the joining openings 23 , 33 .

[0150] The collision surfaces 225 , 233 , 325 , 333 are also arranged obliquely to the joining direction E, wherein the collision surfaces 225 , 233 , 325 , 333 have a greater angle to the joining direction E in the exemplary embodiment shown.

[0151] In other respects, according to Figures 11A to 11D Embodiments and basis Figures 1A to 1D The embodiments are functionally identical, so that reference should also be made to the above embodiments.

[0152] exist Figures 12A to 12D In the embodiment shown in FIG. 1 , the connection parts 2 and 3 of the connection device 1 are as in the embodiment according to Figures 1A to 1D As in the exemplary embodiment of the present invention, the housing parts 20, 30 are each formed with a single housing part 20, 30. The housing parts 20, 30 each form an edge section 200, 300, which extends circumferentially around the respectively associated joining opening 23, 33 and via which the associated components 4, 5, for example textile fabrics of clothing, are connected to the corresponding connecting parts 2, 3. The connection can be carried out, for example, mechanically or chemically, for example by gluing, sewing, welding or riveting.

[0153] exist Figures 13A to 13D In the embodiment shown in FIG. 1 , additionally, according to Figures 12A to 12D Compared to the embodiment of , a fixing element 25, 35 in the form of a ring is provided, which is arranged on the side of the respective component 4, 5 facing away from the respective edge section 200, 300, so as to cover the component 4, 5 on the side facing away from the edge section 200, 300 in the described manner and strengthen the connection.

[0154] In the above-described embodiments, the connecting parts 2, 3 are each rotationally symmetrical in their basic shape with conical joining sections 22, 32 and joining openings 23, 33. However, the shaping of the joining sections 22, 32 and joining openings 23, 33 in a cross-sectional plane transverse to the joining direction E is in principle arbitrary and can in particular deviate from rotational symmetry.

[0155] exist Figures 14A to 14D In the embodiment shown in FIG. 1 , the joining sections 22 , 32 and the joining openings 23 , 33 are triangularly shaped in a cross section transverse to the joining direction E. Figures 15A to 15D In the embodiment shown in FIG. 1 , the joining sections 22, 32 and the joining openings 23, 33 are shaped quadrilaterally in a cross section transverse to the joining direction E. Figures 16A to 16D In the embodiment shown in FIG. 1 , the pentagonal shape is formed and Figures 17A to 17D In the embodiment shown in , the polygonal shape is shaped hexagonally. Respectively, the polygonal shape is equilaterally constituted, i.e., has the same side length, which is however not restrictive. Likewise, the side lengths may also be different.

[0156] In principle, any arbitrary, irregular cross-sectional shapes at the joining sections 22 , 32 and the joining openings 23 , 33 are also conceivable and feasible.

[0157] exist Figures 18A to 18D In the embodiment shown in the figure, the connecting section 203, 303 is connected to the edge section 200, 300 of the housing part 20, 30 of the connecting part 2, 3 of the connecting device 1 via the bent offset section 202, 302. Via the offset section 202, 302, the connecting section 203, 303 is arranged relative to the edge section 200, 300 so that the connecting section 203, 303 extends along a common plane. Via the connecting section 203, 303, the connection of the associated components 4, 5, such as textile fabrics of clothing, is carried out. Due to the flush arrangement of the connecting sections 203, 303 relative to each other, a transverse load is carried out in the transverse direction Q in the common plane A, which is introduced via the components 4, 5, and the common plane, for example, passes approximately centrally through the joining opening 23 of the connecting part 2, thereby causing a symmetrical force input.

[0158] In the exemplary embodiments described above, the contact surfaces 220 , 230 , 320 , 330 each extend linearly in a cross-sectional plane spanned by the joining direction E and the transverse direction Q and are arranged obliquely to the joining direction E. However, this is not restrictive.

[0159] Thus, for example, only one of the connecting parts 2, 3 has a conical contact surface 230 at the joining opening 23, as in the embodiment according to Fig.19 As in the embodiment of FIG. 3 , the contact surface 320 at the joining section 32 of the other connecting part 3 extends parallel to the joining direction E.

[0160] The contact surfaces 220, 230, 320, 330 can also be designed to be curved, as is the case in Fig. 20 Thus, the joining sections 22 , 32 and the joining openings 23 , 33 can each have a convex, spherical shape with a curved contact surface 220 , 230 , 320 , 330 .

[0161] The concept on which the invention is based is not limited to the exemplary embodiments described in detail above, but can also be implemented in any desired manner.

[0162] A connection device of the type described can be implemented in many ways, for example on clothing or as a buckle for a belt, etc. In particular, the connection device can be used universally in situations where a fixed connection is desired in the closed position, but with the possibility of emergency opening under lateral loads exceeding a critical force.
