Description

The invention relates to a closure device for connecting two parts according to the preamble of claim 1.

Such a closure device has a plug and a housing with a plug receptacle into which the plug for closing the closure device can be inserted in a closing direction. On the housing, a slider is arranged in a displaceable manner, which can be moved to open the closure device along a direction different from the closing direction opening direction.

Such closure devices are used for example for connecting two straps, as a closure for a bag, a backpack, a suitcase or a box, as a closing device for other covers, such as a glove box, or as a closure for connecting any other parts. One part here is to be connected to the plug and another part to the housing so that a connection of the parts can be made by arranging the plug in the plug receptacle of the housing.

In a closed position of the closure device, the plug is mechanically held on the housing. To open the closure device, the slider can be displaced along the opening direction and thereby the connector can be detached from the housing, so that in an open position of the closure device, the connector is separated from the housing.

At least one guide element is provided, which guides the plug during insertion into the connector receptacle for closing the closure device along the closing direction into the closed position and the plug during displacement of the slider for opening the closure device against tilting relative to the closing direction is supported.

The fact that the opening direction differs from the closing direction is to be understood in the present case that the opening direction does not point along the closing direction, that is, it is not directed in the opposite direction to the closing direction. The opening direction thus has an angle to the closing direction, which differs from 0 ° and 180 °.

The closure device has a detent spring element, which holds the plug in a closed position of the closure device detent on the housing and to open the closure device by moving the slider in the opening direction out of engagement with the plug is movable to release the plug from the housing, so that in an open position of the closure device, the plug is separated from the housing. To open the closure device, the slider is thus moved in the opening direction, thereby moving the detent spring element, which mechanically holds the plug in the closed position on the housing.

In principle, therefore, a movement of the slide relative to the housing and to the plug takes place, which causes the mechanical hold of the plug on the housing to be canceled. During the opening movement of the slide may, for example, due to friction, also come to a force on the plug, which is thus charged relative to the housing and may possibly tilt in the plug receptacle of the housing. This can make it difficult or even impossible to separate the plug from the housing and thus impair the operability of the closure device.

At one of the WO 2008/006357 A2 known locking device is provided for mechanically holding a plug to a housing, a latching device which is formed by a spring locking element on the one of plug and housing and a locking piece on the other of plug and housing. To open the closure device, the plug can be turned, for example, to the housing, so as to bring the latching device from its latching engagement, so that the plug can be removed from the housing. In addition, a magnet-armature construction is provided which causes a magnetic attraction between the plug and the housing to assist the closing operation of the shutter.

Object of the present invention is to provide a closure device available that can be closed in a simple, haptic pleasant way and reopened.

This object is achieved by an article having the features of claim 1.

Accordingly, at least one first electrical contact element and at least one second electrical contact element are arranged on the housing, wherein in the closed position, the at least one first electrical contact element and the at least one second electrical contact element are electrically contacted with each other.

Thus, an electrical contact between the plug and the assembly formed by the housing and the slider displaceable thereon is produced via the closure device.

On the plug on the one hand and the housing or the slider on the other hand, in each case a plurality of contact elements may be provided, so that in the closed position of the closure device a plurality of electrical connections are closed in parallel, so that multi-pole currents between the plug and the assembly of the housing and the slider can be transmitted.

On the plug or the housing, a guide element is arranged, which acts as a support between the plug and the housing and in particular prevents tilting of the plug in the plug receptacle of the housing when opening the closure device. The guide element facilitates one hand, the insertion of the plug into the connector receptacle. On the other hand, the guide element supports the plug in the plug receptacle such that the position of the plug is defined relative to the housing and in particular a tilting of the plug relative to the housing can not be readily done, so as to ensure that after the operation of the Slider to open the closure device of the plug in a simple, haptic pleasant way removed from the connector receptacle and the plug and the housing can thus be separated.

In principle, one or more guide elements can be arranged on the plug and / or the housing at any points, as long as they ensure that the position of the plug is defined relative to the housing in the closed position and thus only an axial movement of the plug relative to the housing along the closing direction is possible.

In an advantageous embodiment, at least one guide element is arranged on the plug receptacle, wherein the plug receptacle is advantageously formed by a cylindrical recess, for example, on the housing. The at least one guide element may be formed in this case by a surface portion of the connector receptacle of the housing, which extends along the closing direction and in the closed position is flat with the plug in abutment. Characterized in that the guide element extends axially along the closing direction, an axial guidance of the plug is made possible with simultaneous fixing in position in the closed position, so that the plug can not tilt in the connector receptacle.

In a further advantageous embodiment, the at least one guide element can be arranged on the housing in such a way that, when the load of the plug acts in the closing direction relative to the housing, the guide element supports the plug. The guide element is thus arranged on one side of the connector receptacle, which is approximated the plug under load in the opening direction, so that the guide element comes under load of the plug in the opening direction in contact with the plug and the plug is supported, so that the plug is not in can tilt the connector receptacle.

The plug may for example have a pin with which the plug can be inserted into the plug receptacle. On the pin, a first latching portion is advantageously arranged, which engages in the closed position with a second latching portion on the housing or the slider detent, so that in the closed position of the plug is held on the pin latching on the housing.

Advantageously, the pin is in the closed position on the at least one guide element, so that the position of the pin is predetermined on the housing in the closed position by one or more guide elements. The one or more guide elements thus serve firstly to guide the pin into the closed position when attaching the plug to the housing and secondly to set and support the position of the plug on the housing in the closed position.

The first latching portion is preferably arranged circumferentially around the closing direction on the pin, so that the plug can be attached to the housing in different rotational positions.

The second latching portion may for example be arranged on a detent spring element which is fastened to the slide. The detent spring element is in this case in a direction transverse to the closing direction resiliently such that it can be spread when closing the closure device in the direction transverse to the closing direction, so that the detent spring element can latchingly engage with the locking portion of the pin. To close the closure device, the plug is inserted with its pin in the connector receptacle, so that the first latching portion of the pin runs onto the second latching portion of the detent spring element and thereby urges the detent spring element so elastically aside until the pin engages latching with the detent spring element.

The detent spring element may for example be integrally formed on the slider. It is also conceivable, however, to arrange the detent spring element as an additional component on the slide, wherein the connection of the detent spring element with the slide is such that the detent spring element for establishing the connection between the Plug and the detent spring element transversely to the closing direction can be elastically pushed aside.

The detent spring element serves to produce a positive connection of the plug with the slider and above with the housing in order to mechanically hold the plug in the closed position on the housing. The detent spring element is designed such that by moving the slider in the opening direction of the positive engagement between the detent spring element and the pin of the plug is canceled, for example by the first locking portion of the pin of the plug and the second locking portion of the detent spring element on the slider by moving the Slider are pushed out of engagement in the opening direction.

In an advantageous embodiment, the detent spring element may be formed by a circumferentially open ring, which engages around the pin of the plug in the closed position at least partially around the closing direction. By moving the slider in the opening direction then the detent spring element is moved out of engagement with the pin of the plug, wherein the detent spring element is moved to the pin so that the pin is brought through the circumferential opening of the detent spring element and out of engagement with the detent spring element.

The plug, in particular the pin of the plug, for example, is substantially rotationally symmetrical about the closing direction. In particular, the pin may be configured cylindrical in its basic form, wherein at a pointing towards the housing end of the pin (based on a proper attachment of the plug to the connector receptacle of the housing), the (first) latching portion is formed and rotates about the pin. This causes the plug in any rotational orientation about the closing direction to the plug receptacle of the housing can be recognized and can be rotatably supported in the closed position on the housing.

The slider is moved to open the shutter in the opening direction relative to the housing. It can be provided that the slider against the opening direction relative to the housing, for example mechanically (resilient), pneumatically, due to the acting gravity or magnetically in the direction of a position in which the plug for closing the closure device can be mechanically connected to the housing, is biased. In this way it can be effected that after the operation of the slide to open the closure device, the slider is automatically returned to a position in which the plug can be brought back into engagement with the housing or a detent spring element on the slide.

In one embodiment, the at least one first contact element is arranged on the pin. The electrical contact is thus made via the pin, which can carry one or more contact elements.

In an alternative embodiment, one or more first contact elements may also be formed on a body of the plug, which is flat in the closed position with a housing portion in Appendix. First contact elements on the body can thus contact second contact elements on the housing section.

In an additional embodiment, on the one hand and / or the slide, on the other hand, magnetic means can be arranged on the plug, which magnetically support the closure of the closure device. The magnetic means are designed to cause a magnetic attraction between the plug and the housing and / or the slider, such that the plug in magnetically assisted manner, advantageously substantially automatically, when approaching the connector receptacle in engagement with the connector receptacle is pulled so that the closing process can largely be done automatically and thus in a haptic pleasant way for a user.

In a concrete embodiment, at least one magnet can be arranged, for example, on the plug and on the slider. The magnets on the plug and the slide can in this case be designed such that they act magnetically attractive when closing the closure device between the plug and the slide and thereby magnetically support the closing of the closure device.

In addition, it can be provided that when moving the slider in the opening direction to open the closure device, the magnetically attracting opposite poles of the magnets of the plug and the slider are removed from each other and poles of the same name of magnets on the plug and the slider are approximated, so that a magnetic repulsive force between the plug and the slider is effected, which acts counter to the closing direction, and magnetically a discharge of the plug from the connector receptacle to the housing.

The magnet arrangement on the plug and on the slide can be such that the magnetic repulsive force is just maximum when the engagement between the plug and the housing (ie, for example, between the pin with its locking portion on the plug and the detent spring element on the slide) is released and the plug can thus be removed.

A magnetic repulsion when opening the closure device can be achieved that magnetically homonymous poles are approximated when moving the slider in the opening direction to each other. However, magnetic repulsion results e.g. even if magnets that are magnetically attractive with unlike poles in the closed position, are moved tangentially with their opposing pole faces to each other when opening. If the magnets have an at least approximately equal pole shape (i.e., the areas with which the poles face each other are substantially equal in shape), and the magnets are moved a certain distance, e.g. approximately their width (measured in the opening direction) or slightly less than their width, along the opening direction relative to each other and the pole faces are held parallel to each other (so that the magnets lie, for example, approximately edge to edge), it follows a magnetic repulsion between the magnets, which reaches a maximum with further displacement and then slowly decreases. A design of the displacement so that the repulsion is close to the maximum, can be advantageous for a light, haptic pleasant ejection of the plug when opening. This due to magnetic repulsion ejection effect occurs all the more, the more accurately held the plug in position and is guided by guide elements and thus prevented from tilting.

If the at least one guide element is arranged on the housing, the at least one second contact element can be arranged on the at least one guide element. The electrical contacting can thus take place via one or more guide elements formed on the housing.

1 . 2 and 3A to 3D show a closure device 1 that have a plug 2 , a housing 3 and a sliding on the housing 3 arranged slide 4 having.

The closure device 1 serves for connecting two parts, for example as a closure for a bag, a backpack or another flap, as a connecting device for connecting two straps or ropes or for connecting two other parts. One part is here at the plug 2 fastened while the other part with the housing 3 connected is. In a closed position, shown in 3B , is the plug 2 on the housing 3 held so over the plug 2 and the case 3 the two parts are connected together. In an open position, shown in 3A and 3D , are the plug 2 and the case 3 separated, so that there is no connection between the parts.

At the closure device 1 has the plug 2 a body 20 with a fastening device 23 for tying a part (the fastening device 23 For example, it can be designed as a thread onto which a fastening part for clamping attachment of a component, for example a cover, a flap or the like can be screwed) and a pin 21 with a resting section 210 on. With the pin 21 can the plug 2 in a plug receptacle 30 on the housing 3 be plugged in, so that in the closed position of the plug 2 with the pin 21 in the plug receptacle 30 engages and with the catch section 210 of the pin 21 positive locking with locking sections 410 a spring locking element 41 on the slider 4 engaged.

The pin 21 of the plug 2 has one to a closing direction X rotationally symmetrical shape with a circumferential locking portion 210 on (see 1 and 2 ). With the pin 21 can the plug 2 in the circular plug receptacle 30 on the housing 3 be plugged in by the pin 21 in the closing direction X to the plug receptacle 30 set and engaged with the locking portions 410 the spring locking element 41 on the slider 4 is brought.

The spring locking element 41 is on a raised, projecting holding element 42 of the slider 4 arranged such that the spring locking element 41 along an opening direction Y , along which the slider on the housing 3 slidably mounted on the slide 4 is fixed, transverse to the closing direction X and opening direction Y but elastically resilient can be spread. The spring locking element 4 is designed to be substantially annular and has circumferentially an opening 411 (please refer 1 and 2 ), so that the spring locking element 41 transverse to the closing direction X and opening direction Y can be spread so that the plug 21 with the resting section 210 on the resting sections 410 the spring locking element 41 accumulate and thereby the resting sections 410 can push radially outward and thus the pin 21 when applying the plug 2 in the closing direction X to the plug receptacle 30 latching with the spring locking element 41 engages in engagement.

The substantially annular spring locking element 41 is designed as a separate component and on the slide 4 arranged. It is also conceivable, the spring locking element 41 integral with the slider 4 embody.

The slider 4 is along an opening direction Y slidable on the housing 3 arranged and on a sliding guide 31 of the housing 3 guided.

The slider 4 takes to closing (see 3A) or in the closed position (see 3B) the closure device 1 in the 3A and 3B shown position in which the detent spring element 41 concentric with the plug receptacle 30 is arranged such that the plug 2 with the pin 21 in engagement with the locking portions 410 the detent spring element 41 can be brought or stand. In the closed position is the pin 21 over the circumferential latching section 210 with the resting sections 410 the detent spring element 41 positively engaged, so that the plug 2 not against the closing direction X from the case 3 can be removed.

It should be noted that the slider 4 along the opening direction Y on the housing 3 guided, along the closing direction X but relative to the case 3 is fixed, so by the engagement of the pin 21 with the detent spring element 41 The plug 2 over the slider 4 against the closing direction X on the housing 3 is held.

To open (see 3C) can the slider 4 in an opening direction Y relative to the housing 3 be moved. Because the detent spring element 41 on the slider 4 is held, the detent spring element 41 along with the slide 4 in the opening direction Y moved, leaving the pin 21 through the circumferential opening 411 (please refer 1 and 2 ) of the detent spring element 41 occurs and thereby disengaged from the locking portions 410 the detent spring element 41 arrives.

In an open position (see 3D) is the detent spring element 41 not (anymore) with the pin 21 of the plug 2 engaged so that the plug 2 not (anymore) against the closing direction X on the housing 3 is held and contrary to the closing direction X from the plug receptacle 30 and thus of the housing 3 can be removed.

It results in a cycle when using the closure device 1 which can be summarized as follows.

First, the closure device lies 1 before closing in a position in which the plug 2 and the case 3 are separated from each other and the slider 4 is in a starting position, in which the detent spring element 41 concentric with the plug receptacle 30 the housing is arranged so that the pin 21 of the plug 2 latching with the detent spring element 41 can be engaged.

To close now the plug 2 in the closing direction X to the plug receptacle 30 set, so that the pin 21 with the circumferential latching section 210 on the resting sections 410 the detent spring element 41 runs up and this presses apart so that the detent spring 41 transverse to the closing direction X and across the opening direction Y is spread until the pin 21 with the detent spring element 41 engages in engagement.

When applying the plug 2 to the housing 3 So when engaging the pin 21 with the detent spring element 41 , is the slider 4 stationary to the housing 3 and does not move along the opening direction Y , Only the detent spring element 41 is spread open, in this way the latching connection of the plug 2 with the housing 3 manufacture.

In the closed position, shown in 3B , the plug becomes 2 in this way form-fitting to the housing 3 held.

To open the slider 4 in the opening direction Y in the case 3 pushed in, so that the detent spring element 41 out of engagement with the pin 21 device by the pin 21 through the circumferential opening 411 on the detent spring element 41 is moved through. With slide inserted 4 , as in 3C shown, the plug can 2 against the closing direction X from the case 3 be removed, so that in the open position, shown in 3D , The plug 2 and the case 3 are separated from each other.

This results in an asymmetry between the closing operation and the opening operation of the closure device 1 in that to close the slide 4 not moved, but the detent spring element 41 by running the pin 21 with his rest section 210 on the resting sections 410 the detent spring element 41 is spread. When opening, on the other hand, the slider 4 in the opening direction Y moved to the latching section in this way 210 tangentially out of engagement with the locking portions 410 on the detent spring element 41 to move, where there is basically no or only a small spreading of the detent spring element 41 In any case, not to a running of the Rastabschnitts 210 on the resting sections 410 along the closing direction X comes.

The closure device 1 can be used as a purely mechanical closure device 1 be designed. In this case, the plug must be 2 for closing the closure device 1 in the closing direction X in the plug receptacle 30 be pressed in to the pin 21 locking with the detent spring element 41 to engage. The opening is then also purely mechanically by moving the slider 4 in the opening direction Y , wherein additionally a restoring mechanical spring element 35 is provided, that the slide 4 in the direction of in 3A illustrated initial position biased and thus causes after opening the closure device 1 the slider 4 returned to the initial position and the plug 2 thus again in engagement with the detent spring element 41 can be brought.

In an advantageous embodiment, the plug 2 , the case 3 and / or the slider 4 magnetic means 22 . 32 . 34 on, which may be configured to support the closing and opening movement. In principle, the magnetic means 22 . 32 . 34 be formed here as magnets or on the one hand as magnets and on the other hand as a magnetic, made of a ferromagnetic material anchor, wherein each magnetic means 22 . 32 . 34 can consist of one or more elements.

At the plug 2 is in an advantageous embodiment, a magnet 22 arranged in the closed position of the closure device 1 a magnet or a magnetic anchor 32 in the region of the detent spring element 41 on the slider 4 facing, where the magnet 22 on the plug 2 and the magnet or the magnetic anchor 32 on the slider 4 cause a magnetic attraction, the closing movement of the plug 2 in the closing direction X for mechanically engaging the pin 21 with the detent spring element 41 magnetically supported. The magnetic forces of the magnet 22 on the one hand and the magnet or the magnetic armature 32 On the other hand, in this case can be dimensioned so that the closing process when approaching the plug 2 to the plug receptacle 30 largely automatically, in particular by the pin 21 with his rest section 210 largely automatically under spreading of the detent spring element 41 with the resting sections 410 the detent spring element 41 is engaged.

On the slider 4 is at the in 1 . 2 and 3A to 3D illustrated embodiment, another magnet 34 However, this is not necessarily provided and, insofar as may be considered optional. Providing the further magnet 34 However, it has the advantage that the ejection of the plug 2 for opening the closure device 1 can be supported magnetically by moving the slider 4 in the opening direction Y the magnet 34 the magnet 22 on the pin 21 is approximated, with the magnets 34 and 22 to face each other with poles of the same name and thus act magnetically repulsive. In the open position of the slider 4 is the magnet 34 in the area of the plug receptacle 30 and thus below (in the closing direction X seen) of the magnet 22 of the pin 21 , so that a magnetic repulsive force against the closing direction X on the plug 2 acts, who tries to plug 2 from the plug receptacle 30 eject. The opening process can thus be done easily and haptic pleasant. A conscious removal of the plug 2 from the plug receptacle 30 not necessary.

• - In Gegenüberlage (Schließstellung) ist die vertikale Komponenten der Anziehungskraft (gerichtet entlang der Schließrichtung X) maximal, die Magnete 22, 32 zentrieren sich übereinander. Es wirken keine Magnetkräfte seitlich in der Ebene senkrecht zur Schließrichtung X.
• - Bei seitlicher Verschiebung des Magneten 32 in die Öffnungsrichtung Y relativ zu dem Magneten 22 nimmt die vertikale Komponente der magnetischen Anziehungskraft ab, und zwar in etwa bis zu dem Punkt, an dem die Magnete 22, 32 nur noch einen geringen Überlapp oder gerade keinen Überlapp mehr aufweisen. Gleichzeitig wirkt mit zunehmender Verschiebung ein zunehmendes Moment, das versucht, die Magnete 22, 32 mit ihren Polflächen aufeinander zu zu drehen. Dies wird jedoch von Führungselementen 301, 302 (die weiter unten noch im Einzelnen erläutert werden) verhindert.
• - Bei Überschreiten dieses Punktes (in etwa nach Verschiebung der Magnete 22, 32 entlang der Öffnungsrichtung Y zueinander um eine dem Durchmesser der Magnete 22, 32 entsprechende Strecke) wirkt bei den planparallel zueinander gehaltenen Magneten 22,32 eine Auswurfkraft entgegen der Schließrichtung X auf den Magneten 22 und damit den Stecker 2. Diese Kraft nimmt in einem sehr engen Verschiebebereich bei weiterer Verschiebung in die Öffnungsrichtung Y zunächst zu und danach mit zunehmender Verschiebung wieder langsam ab.

An ejection effect occurs in the illustrated embodiment, but also without use of the magnet 34 on, which is insofar only optional. Namely the magnets 22 and 32 along the opening direction Y shifted to each other while the facing pole faces of the magnets 22 . 32 held plane-parallel to each other, the result is the following force curve:

• - In opposition (closed position) is the vertical components of the attraction (directed along the closing direction X ) maximum, the magnets 22 . 32 center each other. There are no magnetic forces laterally in the plane perpendicular to the closing direction X ,
• - With lateral displacement of the magnet 32 in the opening direction Y relative to the magnet 22 decreases the vertical component of the magnetic attraction, approximately to the point where the magnets 22 . 32 have only a slight overlap or just no overlap. At the same time, with increasing displacement, an increasing moment acts, which tries to release the magnets 22 . 32 to turn towards each other with their pole faces. However, this is by guiding elements 301 . 302 (which will be explained in more detail below) prevented.
• - When this point is exceeded (approximately after displacement of the magnets 22 . 32 along the opening direction Y to each other by a diameter of the magnets 22 . 32 corresponding distance) acts in the plane-parallel to each other held magnets 22,32 an ejection force against the closing direction X on the magnet 22 and with it the plug 2 , This force decreases in a very narrow displacement range with further displacement in the opening direction Y initially to and then slowly decreasing with increasing shift.

Will not be a third magnet 34 used, the displacement of the slider 4 which leads to a release of the latching and thus to the opening of the closure device 1 leads, advantageously just be dimensioned to a measure in the range of this maximum, so that there is an advantageous ejection effect and to eject the plug 2 can be exploited.

At the plug receptacle 30 are two guiding elements 301 . 302 provided in the manner of webs from a top 300 of the housing 3 axially in the direction of the shooting direction X extend and at the edge of the plug receptacle 30 are arranged. The one guide element 301 is at one - in the opening direction Y seen - front side of the plug receptacle 30 and the other guide element 302 on a rear side of the plug receptacle 30 arranged.

The guide elements 301 . 302 on the one hand serve to the plug 2 with his spigot 21 when attaching to the connector receptacle 30 in the closing direction X in engagement with the detent spring element 41 respectively.

On the other hand serve the guide elements 301 . 302 to the pin 21 and thus the plug 2 when moving the slider 4 for opening the precursor device 1 opposite the housing 3 support, so that the plug 2 not relative to the housing 3 can tilt and the pin 21 in a coaxial position to the closing direction X on the housing 3 is held.

Particular importance is given to the front guide element 301 to that, the pin 21 especially when moving the slider 4 in the opening direction Y supported. Background here is that basically the plug 2 and the pin 21 when moving the slider 4 in the opening direction Y not moved. Due to friction between the locking sections 210 . 410 and due to between the magnetic means 22 . 32 . 34 However, magnetic forces acting there is a force on the plug 2 possibly causing a tilting of the plug 2 in the plug receptacle 30 lead and thereby possibly removing the plug 2 could affect. This is done by providing the front guide element 301 prevented by moving the slider 4 in the opening direction Y the pin 21 in contact with the front guide element 301 pressed and thereby a flat contact with the axially extended, front guide element 301 causes the tilting of the plug 2 in the plug receptacle 30 prevented.

The prevention of tilting can have a positive influence on the function in two respects: Firstly, a catching of the plug 2 in the case 3 be prevented when opening. Second, there may be an ejection effect when using only two magnets 22 . 32 be achieved, the stronger the more accurate the plug 2 on the housing 3 is guided.

In the illustrated embodiment may in principle also on the spring element 35 as return means for transferring the slider 4 be waived in the initial position after the operation to open. Because also the magnetic means 22 . 32 . 34 act resetting such that the slider 4 when approaching the pin 21 to the plug receptacle 30 of the housing 3 against the opening direction Y in the direction of the starting position according to 3A is pulled (the magnetic means 22 . 32 on the pin or on the slide 4 Attract, the magnetic means 22 . 34 bounce off).

In principle, also other restoring means can be used, for example, a pneumatic spring element, or a provision can due to the in a normal use position (eg on a bag) on the slider 4 acting gravity.

The closure device 1 can serve in particular for connecting two straps. This can be done on the plug 2 on the one hand and on the housing 3 on the other hand, for example, a fastening device 23 . 33 be arranged in the form of a belt attachment, a belt clamped to the plug 2 or the housing 3 holds.

If a webbing clamping device is used, then for example a clamping lever can be used 24 be provided (as exemplified in the embodiment of the plug 2 ), which must be solved for jamming holding a webbing. The clamping lever 24 is over pivot pin 240 in the assembled state of the clamping lever 24 in recesses 230 on the body 20 of the plug 2 engage around a pivot axis S swiveling on the body 20 stored and is located at one in the closed position the housing 3 facing side of the body 20 so that the clamping lever 24 in the closed position of the closure device 1 between the plug 2 and the housing 3 is arranged and not for releasing the strap from the plug 2 can be operated.

At the in 1 . 2 and 3A to 3D illustrated embodiment of the closure device 1 is the plug 2 with one on the body 20 arranged, fixed pin 21 educated. Conceivable and possible here is also the pin 21 - like in the German patent application 10 2010 044 144.9 described - along the closing direction X adjustable on the body 20 to arrange, so that the pin 21 for example, in a starting position in the body 20 sunk and only when approaching the housing 3 for example under the action of the magnetic means 22 . 32 out of the body 20 is extended to engage the detent spring element 41 on the slider 4 to be brought.

The closure device 1 has a plug in the illustrated embodiment 2 with a single pin 21 and a housing 3 with a single plug receptacle 30 on. Conceivable and advantageous may be on a plug 2 several cones 21 and corresponding to a housing 3 several plug receptacles 30 to arrange. To open such a closure device 1 can then be provided a slider which is integrally formed and for releasing the connections of each pin 21 with an associated detent spring element 21 at the associated connector receptacle 30 can be moved. Instead of a single slider but also several slides can be provided, which are either used individually or coupled together for common operation.

Another embodiment of a closure device 1 demonstrate 4A to 4F in different positions of a plug 2 , of a housing 3 and a slider 4 in a position before closing ( 4A) , while closing ( 4B and 4C) in a closed position ( 4D) , When opening ( 4E) and in an open position with the plug disconnected 2 and housing 3 ( 4F) , The exemplary embodiment is essentially functionally identical to the above with reference to FIG 1 to 3 described embodiment, so that reference should be made to the above statements. Components of the same function are, as far as appropriate, provided with the same reference numerals.

5A and 5B show separate views of the slider 4 of the embodiment according to 4A to 4F ,

In contrast to the embodiment according to 1 to 3 is in the embodiment according to 4A to 4F a detent spring element 41 in one piece to the slider 4 molded, which can be made for example as a plastic molding by means of plastic injection molding.

As from the separate views according to 5A and 5B can be seen, is the detent spring element 41 to a body 40 of the slider 4 molded and is about a holding section 414 on the body 40 held. The detent spring element 41 has two lateral spring sections 417 on that in a connecting section 416 converge and over free cuts 415 from the body 40 are cut free. About the connection section 416 is the detent spring element 41 to the holding section 414 molded and above this on the body 40 held.

The detent spring element 41 has a recess 413 on, in which the guide element 301 engages when closing and in the closed position (see 4A to 4D in conjunction with Fig. Eg 3A in which the guide element 301 is shown).

The spring sections 417 the detent spring element 41 follow a circular contour and form the substantially annular detent spring element in its shape 41 out, the circumference through an opening 411 is open, as above for the embodiment according to 1 to 3 described. Between the spring sections 417 is a receiving opening 412 formed in which the plug 2 with his spigot 21 in the closed position (see 4D) is held latching.

The operation of the closure device 1 while closing ( 4A to 4D) and when opening ( 4E and 4F) is basically analogous to the embodiment described above 1 to 3 , In particular, also results in the closure device 1 a circulatory function in which the plug 2 to close in the closing direction X in the plug receptacle 30 of the housing 3 inserted and latching with the detent spring element 41 of the slider 4 is engaged and to open the slide 4 in the opening direction Y moved, the plug 2 against the closing direction X removed and then the slide 4 against the opening direction Y is reset so that the shutter device 1 can be closed again.

Because the pin 21 of the plug 2 with his rest section 210 when closing on the locking sections 410 at the spring sections 417 the detent spring element 414 runs up (see 4B and 4C) , on the one hand, the spring sections 417 transverse to the opening direction Y pushed aside and the detent spring element 41 thereby widened, at the same time the slide 4 slightly in the opening direction Y moved because of the resting section 210 of the pin 21 on the resting sections 410 in the area of the connection section 416 subsequent ends of the spring sections 417 runs. Because the detent spring element 41 in the region of the connection of the spring sections 417 with the connecting section 416 is not or at least only slightly resilient, the detent spring element 41 not in the opening direction Y Dodge elastically, so that the slider 4 as a whole slightly in the opening direction Y moves until the latching section 210 with the resting sections 410 snaps into engagement and the closure device 1 in the closed position according to 4D arrives.

The movement of the slider 4 in the opening direction Y but is small and comprises at most the width of the radial projection of the locking portion 410 (So the way, the detent spring element 41 must dodge, so that the rest sections 410 with the resting section 210 can get into engagement).

The opening process is essentially analogous to the preceding embodiment of the embodiment 1 to 3 described. It should be noted that opening the closure device 1 not done when the slider 4 just about the way the slider 4 evades when closing, in the opening direction Y is moved. To open is a sliding of the slider 4 required by a distance that is sufficient to the pin 21 along the opening direction Y out of engagement with the detent spring element 41 to bring, as in 4E shown.

In contrast to the embodiment according to 1 to 3 has the plug 2 in the embodiment according to 4A to 4F and 5A . 5B no clamping lever for Gurtanbringung on, but only a fastening device 23 in the form of a Gurtbügels to entwine with a belt. The design of the belt attachment is basically arbitrary and can also be designed completely different.

A cone 418 (please refer 5B) is on the slider 4 provided to an end position of the slider 4 in the sliding guide 31 of the housing 3 to define when opening.

As in 6A . 6B is shown in the embodiment according to 1 to 3A-3D on the housing 3 a contact element 303 arranged in the closed position ( 6B) with an associated contact element 211 of the plug 21 electrically contacted. In the closed position thus there is an electrical connection between the plug 2 and the housing 3 , so that an electric current between the plug 2 and the housing 3 can be transferred.

In another embodiment of the closure device 1 represented in 7A . 7B to 10 , are on a body 20 of the plug 2 two electrical contact elements 211 arranged such that they in the closed position of the closure device 1 ( 7A . 7B) towards a housing section 304 of the housing 3 wise and with contact elements 303 on the housing section 304 electrically contacted. About the contact elements 211 . 303 Thus, two parallel, electrically separate connections between the plug 2 and the housing 3 created so that different, multi-pole currents (+, -) between the plug 2 and the housing 3 can be transmitted.

• - sämtliche Kontaktelemente 200, 303 paarweise,
• - lediglich ein Paar von Kontaktelementen 200, 303 oder
• - gar keine Kontaktelemente 200, 303 miteinander kontaktiert sein.

11A-11D to 16A . 16B show views of a closure device 1 , the one plug 2 which is attached to a housing 3 with a slider slidably mounted thereon 4 can be recognized. On a body 20 of the plug 2 are, according to the views 11A-11D to 13A-13C several juxtaposed contact elements 200 formed by attaching the housing 3 to the body 20 with contact elements 303 below the housing 3 (please refer 12A) can contact. Depending on the position of the housing 3 on the plug 2 can do this

• - All contact elements 200 . 303 pairs,
• - Only a pair of contact elements 200 . 303 or
• - no contact elements 200 . 303 be contacted each other.

This can, for example, also enable a position detection in order to determine the contacting of the electrical contacts 200 . 303 to the position of the housing 3 on the plug 2 to conclude (background is that in this embodiment, the plug 3 in different, rotated by 90 ° to each other positions on the plug 2 can be set).

At the in 11A-11D to 13A-13C illustrated embodiment may be on the plug 2 and / or the housing 3 basically any formations of contacts 200 . 303 be arranged.

For example, on the body 20 of the plug 2 like this in 14B is shown, two rows of contacts 200 be arranged.

Or it can, like this in 15A . 15B is shown on the housing 3 two rows of contacts 303 and / or on the body 20 of the plug 2 Contacts arranged along a square 200 be arranged.

As in 16A . 16B illustrates the number of contacts 200 . 303 on the plug 2 on the one hand and on the housing 3 on the other hand also be different, with respective arrangement of the contacts 200 . 303 along a row.

The invention is not limited to the embodiments described above, but can also be realized in completely different types of embodiments.

In particular, the sliding track of the slider must 4 not necessarily be configured rectilinear, but may in principle also have a different, curved shape. Accordingly, the opening direction Y be curved.

The sliding track can, for example, on a circular path around the closing direction X lie and thus in a plane perpendicular to the closing direction X ,

It is also conceivable, the track on a circular path about a direction transverse to the closing direction X and across the opening direction Y arrange so that the sliding track in by the opening direction Y and the closing direction X spanned level lies.

Of course, the slider may also be configured to be actuated by applying a tensile force (and not by applying a compressive force, as in the previously described embodiments). The basic operation of the closure device is not changed thereby.
