closure device

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.

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. In a closure device known from WO 2008/006357 A2 a locking device is provided for mechanically holding a plug to a housing, 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 magnetic anchor construction is provided, which is a magnetic Attraction force between the plug and the housing for assisting the closing operation of the shutter causes.

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 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 when moving the slider for opening the closure device against tilting relative to the closing direction.

The present invention is based on the idea of providing a guide element on the plug or housing, which supportively acts between the plug and the housing and in particular prevents tilting of the plug in the plug receptacle of the housing when the closure device is opened. 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 advantageously by a For example, cylindrical recess is formed 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 detent spring element may be arranged elastically resiliently on the slider in a first embodiment. 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 slider is such that the detent spring element for producing the connection between the plug and the detent spring element can be urged elastically aside to the closing direction. 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.

The detent spring element can also be realized by the slider itself. For this purpose, the second latching portion may be arranged rigidly on the slide, wherein the slide itself is resiliently biased relative to the housing and formed resiliently about it. To close the first latching portion of the plug runs on the second latching portion of the slider and urges in this way the locking portion - under (slight) movement of the slider against its bias - aside until the first latching portion with the second latching portion engages. 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 the Closing process largely automatically and thus can be done 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 to each other, 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 assembly on the plug and the slide can be such that the magnetic repulsion 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, a magnetic repulsion results, for example, even when magnets that are magnetically attractive with unlike poles in the closed position, are moved when opening tangentially with their opposing pole faces to each other. If the magnets have an at least approximately identical pole shape (ie, the areas with which the poles face substantially the same shape) and the magnets by a certain distance, for example about their width (measured in the opening direction) or something less than their width, along the opening direction shifted 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), there is a magnetic repulsion between the magnets, with a further shift Reaches maximum and then drops slowly. 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 the plug is held in position and guided by guide elements and thus prevented from tilting.

The idea underlying the invention will be explained in more detail below with reference to the embodiments illustrated in the figures. Show it:

FIGS. 1, 2 and 3A to 3D show a closure device 1 which has a plug 2, a housing 3 and a slide 4 which is arranged displaceably on the housing 3.

The closure device 1 is used to connect 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 fastened here to the plug 2, while the other part is connected to the housing 3. In a closed position, shown in Fig. 3B, the plug 2 is held on the housing 3, so that the two parts are connected to each other via the plug 2 and the housing 3. In an open position, shown in Figs. 3A and 3D, the plug 2 and the housing 3 are separated, so that there is no connection between the parts.

In the closure device 1, the plug 2 has a body 20 with a fastening device 23 for tying a part (the fastening device 23 may for example be configured as a thread, to which a fastening part for clamping attachment of a component, such as a lid, a flap or the like are screwed can) and a pin 21 with a latching portion 210 on. With the pin 21, the plug 2 can be inserted into a connector receptacle 30 on the housing 3, so that engages in the closed position of the plug 2 with the pin 21 in the connector receptacle 30 and the latching portion 210 of the pin 21 positively with latching portions 410 of a spring locking element 41 is engaged on the slider 4.

The pin 21 of the plug 2 has a about a closing direction X rotationally symmetrical shape with a circumferential latching portion 210 (see Figs. 1 and 2). With the pin 21, the plug 2 can be inserted into the circular connector receptacle 30 on the housing 3 by the pin 21 in the closing direction X at the plug receptacle 30 is attached and brought into engagement with the latching portions 410 of the spring locking element 41 on the slider 4.

The spring locking element 41 is disposed on a raised, projecting holding element 42 of the slider 4 such that the spring locking element 41 along an opening direction Y, along which the slider is slidably mounted on the housing 3, is fixed to the slider 4, 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 41 1 (see FIGS. 1 and 2), so that the spring locking element 41 can be spread across the closing direction X and opening direction Y such that the plug 21 with the locking portion 210 accumulate on the locking portions 410 of the spring locking element 41 and thereby the latching portions 410 can urge radially outward Shen and thus the pin 21 snaps into engagement with the connector 2 in the closing direction X to the connector receptacle 30 latching with the spring locking element 41 into engagement.

The substantially annular spring locking element 41 is formed as a separate component and arranged on the slider 4. It is also conceivable to design the spring locking element 41 in one piece with the slider 4.

The slider 4 is slidably disposed along the opening direction Y on the housing 3 and guided to a sliding guide 31 of the housing 3.

Shutter 4 assumes the position shown in FIGS. 3A and 3B for closing (see FIG. that the plug 2 can be brought with the pin 21 in engagement with the latching portions 410 of the detent spring element 41 and can stand. In the closed position, the pin 21 is about the circumferential latching portion 210 with the latching portions 410 of the detent spring element 41 positively engages, so that the plug 2 can not be removed against the closing direction X of the housing 3.

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

For opening (see FIG. 3C), the slider 4 can be displaced in an opening direction Y relative to the housing 3. Because the detent spring element 41 is held on the slider 4, the detent spring element 41 is thereby moved together with the slider 4 in the opening direction Y, so that the pin 21 passes through the circumferential opening 41 1 (see FIGS. 1 and 2) of the detent spring element 41 and thereby comes out of engagement with the locking portions 410 of the detent spring element 41.

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

The result is a cycle when using the closure device 1, which can be summarized as follows. First, the closure device 1 is before closing in a position in which the plug 2 and the housing 3 are separated from each other and the slider 4 is in an initial position in which the detent spring element 41 is arranged concentrically to the connector receptacle 30 of the housing, so that the pin 21 of the plug 2 can be latchingly engaged with the detent spring element 41 in engagement.

To close the plug 2 is now recognized in the closing direction X to the connector receptacle 30 so that the pin 21 runs with the circumferential latching portion 210 on the locking portions 410 of the detent spring element 41 and this apart such that the detent spring 41 transversely to the closing direction X and across is spread to the opening direction Y until the pin 21 snaps into engagement with the detent spring element 41.

When attaching the plug 2 to the housing 3, so when engaging the pin 21 with the detent spring element 41, the slider 4 is stationary to the housing 3 and does not move along the opening direction Y. Only the detent spring element 41 is spread to order in this way the latching connection of the plug 2 to the housing 3 produce. In the closed position, shown in Fig. 3B, the plug 2 is held in this manner form-fitting manner to the housing 3. To open the slide 4 is inserted into the opening direction Y in the housing 3, so that the detent spring element 41 au engagement with the pin 21 device by the pin 21 is moved through the circumferential opening 41 1 on the detent spring element 41. When the slide 4 is inserted, as shown in FIG. 3C, the plug 2 can be removed from the housing 3 counter to the closing direction X, so that in the open position, shown in FIG. 3D, the plug 2 and the housing 3 are separated from one another.

This results in an asymmetry between the closing operation and the opening operation of the closure device 1 characterized in that for closing the slide 4 is not moved, but the detent spring element 41 is spread by running the pin 21 with its locking portion 210 on the locking portions 410 of the detent spring element 41. When opening, however, the slider 4 is moved in the opening direction Y to move in this way the locking portion 210 tangentially out of engagement with the locking portions 410 on the detent spring element 41, wherein there is basically no or only a small spreading of the detent spring element 41, but anyway does not come to a running of the locking portion 210 on the locking portions 410 along the closing direction X.

The closure device 1 can be designed as a purely mechanical closure device 1. In this case, the connector 2 must be pressed to close the closure device 1 in the closing direction X in the connector receptacle 30, to bring the pin 21 lockingly with the detent spring element 41 in engagement. 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 which biases the slider 4 in the direction of the starting position shown in FIG. 3A and thus causes after opening the Closing device 1 of the slider 4 returns to the starting position and the plug 2 can thus be brought back into engagement with the detent spring element 41.

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

In an advantageous embodiment, a magnet 22 is arranged on the plug 2 and, in the closed position of the closure device 1, faces a magnet or a magnetic armature 32 in the region of the detent spring element 41 on the slide 4, the magnet 22 on the plug 2 and the magnet or the magnetic armature 32 on the slider 4 cause a magnetic attraction, which magnetically supports the closing movement of the plug 2 in the closing direction X for mechanically engaging the pin 21 with the detent spring element 41. The magnetic forces of the magnet 22 on the one hand and the magnet or the magnetic armature 32 on the other hand can be dimensioned so that the closing process as far as possible when approaching the connector 2 to the connector receptacle 30 automatically by, in particular, the pin 21 with its latching portion 210 largely under Spreading the detent spring element 41 with the latching portions 410 of the detent spring element 41 is pulled into engagement.

On the slide 4, in the embodiment shown in FIGS. 1, 2 and 3A to 3D, a further magnet 34 is arranged, which, however, is not necessarily provided and, insofar, is to be regarded as optional. However, the provision of the further magnet 34 has the advantage that the ejection of the plug 2 for opening the closure device 1 can be magnetically assisted by the magnet 34 is approximated to the magnet 22 on the pin 21 when moving the slider 4 in the opening direction Y , wherein the magnets 34 and 22 point to each other with poles of the same name and thus act magnetically repulsive. In the open position of the slide 4, the magnet 34 is in the region of the plug receptacle 30 and thus below (in the closing direction X) of the magnet 22 of the pin 21, so that a magnetic repulsive force against the closing direction X acts on the plug 2, which tries To eject the plug 2 from the connector receptacle 30. The opening process can thus be done easily and haptic pleasant. A conscious removal of the plug 2 from the connector receptacle 30 is not required.

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

Opposite (closed position) is the vertical components of the attractive force (directed along the closing direction X) maximum, the magnets 22, 32 are centered on 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, the vertical component of the magnetic attraction decreases, and approximately to the point at which the magnets 22, 32 only a small overlap or just no overlap more exhibit. At the same time acts with increasing displacement an increasing moment, which tries to rotate the magnets 22, 32 with their pole faces toward each other. However, this is prevented by guide elements 301, 302 (which will be explained in more detail below).

When this point is exceeded (approximately after displacement of the magnets 22, 32 along the opening direction Y relative to one another by a diameter of the magnets 22, 32), an ejection force against the closing direction X acts on the magnets in the magnets 22, 32 which are held parallel to one another 22 and thus the plug 2. This force increases in a very narrow displacement range with further displacement in the opening direction Y first to and then slowly with increasing displacement again.

If no third magnet 34 is used, the displacement of the slide 4, which leads to a release of the locking and thus to open the closure device 1, advantageously just be dimensioned to a degree in the range of this maximum, so that there is an advantageous ejection effect and Ejecting the plug 2 can be exploited. At the plug receptacle 30, two guide elements 301, 302 are provided which extend in the manner of webs of a top 300 of the housing 3 axially in the direction of shooting X and are arranged on the edge of the connector receptacle 30. The one guide element 301 is arranged on a front side of the plug receptacle 30, viewed in the opening direction Y, and the other guide element 302 on a rear side of the plug receptacle 30. On the one hand, the guide elements 301, 302 serve to guide the plug 2 with its journal 21 when engaging the plug receptacle 30 in the closing direction X into engagement with the detent spring element 41. On the other hand, the guide elements 301, 302 serve to support the pin 21 and thus the plug 2 when moving the slider 4 for opening the precompression device 1 relative to the housing 3, so that the plug 2 can not tilt relative to the housing 3 and the pin 21st is held in a coaxial position to the closing direction X on the housing 3.

Particular importance is attached to the front guide element 301, which supports the pin 21 in particular in a displacement of the slider 4 in the opening direction Y. The background here is that basically the plug 2 and the pin 21 is not moved in a displacement of the slider 4 in the opening direction Y. Due to friction between the latching portions 210, 410 and due to acting between the magnetic means 22, 32, 34 magnetic forces, however, there is a force on the plug 2, which may lead to tilting of the plug 2 in the connector receptacle 30 and thereby optionally could affect a removal of the plug 2. This is prevented by providing the front guide element 301 by pressing the pin 21 in contact with the front guide element 301 when the slide 4 is displaced in the opening direction Y, thereby causing a planar contact with the axially extending front guide element 301 Tilting the plug 2 in the connector receptacle 30 prevents.

The prevention of tilting can have a positive influence on the function in two respects: Firstly, hooking of the plug 2 in the housing 3 during opening can be prevented. Second, an ejection effect can be achieved by using only two magnets 22, 32, which is the stronger the more accurately the plug 2 is guided on the housing 3.

In the illustrated embodiment, in principle, the spring element 35 can be dispensed with as return means for transferring the slider 4 to the initial position after actuation to open. For even the magnetic means 22, 32, 34 act restoring such that the slide 4 is pulled when approaching the pin 21 to the connector receptacle 30 of the housing 3 against the opening direction Y in the direction of the initial position shown in FIG. 3A (the magnetic means 22, 32 on the pin or on the slider 4 attract, the magnetic means 22, 34 repel).

In addition, other restoring means may also be used in principle, for example a pneumatic spring element, or provision may be made on the basis of the force of gravity acting on the slide 4 in a normal use position (for example on a pocket).

The closure device 1 can serve in particular for connecting two straps. Here, on the one hand and on the housing 3 on the other hand, in each case, for example, a fastening device 23, 33 may be arranged in the form of a Gurtbefestigung, which holds a belt clamped to the plug 2 and the housing 3.

If a webbing clamping device is used, for example, a clamping lever 24 may be provided (as for example in the embodiment of the plug 2), which must be solved for jamming holding a webbing. The clamping lever 24 is pivotally mounted on the body 20 via pivot pins 240, which engage in the assembled state of the clamping lever 24 in recesses 230 on the body 20 of the plug 2, about a pivot axis S and is located at a in the closed position facing the housing 3 side of the body 20, so that the clamping lever 24 is disposed in the closed position of the closure device 1 between the plug 2 and the housing 3 and can not be operated for releasing the webbing from the plug 2. In the embodiment of the closure device 1 shown in FIGS. 1, 2 and 3A to 3D, the plug 2 is formed with a fixed pin 21 arranged on the body 20. It is also conceivable and possible here, the pin 21 - as described in German Patent Application 10 2010 044 144.9 - along the closing direction X adjustable to the body 20 to arrange, so that the pin 21 is sunk, for example, in a starting position in the body 20 and only approached to the housing 3, for example, under the action of the magnetic means 22, 32 is extended out of the body 20 to be brought into engagement with the detent spring element 41 on the slider 4 can. The closure device 1 has in the illustrated embodiment, a plug 2 with a single pin 21 and a housing 3 with a single connector receptacle 30. Conceivable and advantageous may be, on a plug. 2 a plurality of pins 21 and correspondingly arranged on a housing 3 a plurality of plug receptacles 30. To open such a closure device 1, a slider can then be provided, which is formed in one piece and can be moved to release the connections of each pin 21 with an associated detent spring element 21 on the associated connector receptacle 30. Instead of a single slider but also several slides can be provided, which are either used individually or coupled together for common operation.

A further exemplary embodiment of a closure device 1 is shown in FIGS. 4A to 4F in different positions of a plug 2, a housing 3 and a slider 4 in a position before closing (FIG. 4A), when closing (FIGS. 4B and 4C) in a single position Closed position (Fig. 4D), when opening (Fig. 4E) and in an open position with separate plug 2 and housing 3 (Fig. 4F). The exemplary embodiment is essentially functionally identical to the exemplary embodiment described above with reference to FIGS. 1 to 3, 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.

Figs. 5A and 5B are separate views of the slider 4 of the embodiment of Figs. 4A to 4F.

In contrast to the embodiment according to FIGS. 1 to 3, in the exemplary embodiment according to FIGS. 4A to 4F, a detent spring element 41 is integrally formed integrally with the slide 4, which can be produced, for example, as a plastic molded part by means of plastic injection molding.

As can be seen from the separate views of FIGS. 5A and 5B, the detent spring element 41 is formed on a body 40 of the slider 4 and is held on the body 40 via a holding portion 414. The detent spring element 41 has two lateral spring sections 417, which converge in a connecting section 416 and are cut free cutouts 415 from the body 40. About the connecting portion 416, the detent spring element 41 is integrally formed on the holding portion 414 and held on this on the body 40. The detent spring element 41 has a recess 413, into which the guide element 301 engages when closing and in the closed position (see FIGS. 4A to 4D in conjunction with FIG. 3A, for example, in which the guide element 301 is shown). The spring sections 417 of the detent spring element 41 follow a circular contour and form the substantially annular detent spring element 41, which is open circumferentially through an opening 41 1, as described above for the exemplary embodiment according to FIGS. 1 to 3. Between the spring portions 417 a receiving opening 412 is formed, in which the plug 2 is held with its pin 21 in the closed position (see FIG. 4D) latching.

The operation of the closure device 1 during closing (FIGS. 4A to 4D) and during opening (FIGS. 4E and 4F) is fundamentally analogous to the exemplary embodiment described above according to FIGS. 1 to 3. In particular, the closure device 1 also has a circulation function the plug 2 is inserted for closing in the closing direction X in the connector receptacle 30 of the housing 3 and latching with the detent spring element 41 of the slider 4 is engaged and moved to open the slide 4 in the opening direction Y, the plug 2 against the closing direction X. removed and then the slide 4 is reset against the opening direction Y, so that the closure device 1 can be closed again. Because the pin 21 of the plug 2 with its latching portion 210 when closing on the latching portions 410 at the spring portions 417 of the detent spring member 414 runs (see FIGS. 4B and 4C), on the one hand, the spring portions 417 pushed transversely to the opening direction Y aside and the detent spring element 41 thereby widened, wherein at the same time the slider 4 moves slightly in the opening direction Y, because the latching portion 210 of the pin 21 runs onto the latching portions 410 in the region adjoining the connecting portion 416 ends of the spring portions 417. Because the detent spring element 41 is not or at least only slightly resilient in the region of the connection of the spring sections 417 with the connecting section 416, the detent spring element 41 can not elastically deflect in the opening direction Y, so that the slider 4 as a whole moves slightly in the opening direction Y, until the latching section 210 snaps into engagement with the latching sections 410 and the shutter device 1 reaches the closed position according to FIG. 4D.

However, the movement of the slider 4 in the opening direction Y is slight and comprises at most the width of the radial projection of the latching portion 410 (ie the way that the detent spring element 41 must dodge so that the latching portions 410 can engage with the latching portion 210). The opening process is essentially analogous to that described above for the embodiment according to FIGS. 1 to 3. It should be noted that opening of the closure device 1 does not take place when the slider 4 is moved in the opening direction Y only by the path that the slider 4 evades when closing. To open a displacement of the slider 4 is required by a distance which is sufficient to bring the pin 21 along the opening direction Y out of engagement with the detent spring element 41, as shown in Fig. 4E. In contrast to the embodiment according to FIGS. 1 to 3, the plug 2 in the embodiment according to FIGS. 4A to 4F and 5A, 5B no clamping lever for belt attachment, but only a fastening device 23 in the form of a Gurtbügels for wrapping with a belt. The design of the belt attachment is basically arbitrary and can also be designed completely different.

A pin 418 (see Fig. 5B) is provided on the slider 4 to define an end position of the slider 4 in the slide guide 31 of the housing 3 when opening.

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

In particular, the trajectory of the slider 4 does not necessarily have to be rectilinear, but may basically have a different, curved shape. Accordingly, the opening direction Y can be curved.

The sliding track can for example lie on a circular path about the closing direction X and thus in a plane perpendicular to the closing direction X. It is also conceivable to arrange the moving track on a circular path about a direction transverse to the closing direction X and transverse to the opening direction Y, so that the sliding track is in the plane defined by the opening direction Y and the closing direction X level. Of course, the slider can also be designed 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.
