Description

  • The invention relates to a closure device for connecting two parts according to the preamble of claim 1.
  • Such a closure device comprises a first closure part and a second closure part. The first closure part can be attached to close the closure device to the second closure part and is held in a closed position on the second closure part. A first engagement projection of the first closure member may be engaged with the second engagement projection in an engagement direction for closing the closure device, and in the closed position is positively engaged with the second engagement projection. On the second closure part, there is further arranged a blocking element which is moved out of a basic position upon engagement of the first closure part with the second closure part by cooperation with the first closure part, so that the first engagement projection can be brought into engagement with the second engagement projection. Upon or after the engagement between the first engagement protrusion and the second engagement protrusion is established, the locking element returns to its home position to lock in the home position the positive engagement of the first engagement protrusion with the second engagement displacement against the engagement direction.
  • At one of the KR 20 1996 009 916 Y1 known closure device, a closure member is attached via a mounting plate to an object. The mounting plate here has openings which can be brought into engagement with engagement projections of the closure part. At the openings spring tongues are provided which elastically dodge when attaching the closure member to the mounting plate and reach after establishing a positive connection of the engagement projections of the closure member with the edge of the openings of the mounting plate back to their normal position to release the engagement protrusions from their in the normal position To lock intervention.
  • At one of the DE 43 12 032 C2 Known closure is arranged on a first closure part, a pin which can be brought into engagement with an engagement recess on a second closure part. When attaching the pin urges a locking element aside, which comes after making the engagement of the pin of the first closure member with the engagement recess of the second closure member back to a normal position in which the engagement of the pin is locked with the engagement recess. To release the pin from the engagement recess, the locking member can be actuated to release the pin and remove it from the engagement recess.
  • There is a need for closure devices that are to close in haptic pleasant, smooth manner, in the closed position a firm grip and thus ensure a secure connection between parts to be joined and also are open in a lighter, more comfortable way.
  • The WO 2008/006355 A2 describes a magnetic buckle, in which a first closure part can be inserted into a second closure part. At the second closure part, a latching lug is arranged on a spring plate, which can be brought into engagement with a latching recess on the first closure part in a closed position of the closure device.
  • US 2004/0107547 also discloses a closure device.
  • Object of the present invention is to provide a closure device that allow easy closing, a firm grip in the closed position and easy opening.
  • This object is achieved by an article having the features of claim 1.
  • Accordingly, in a closure device of the kind set forth in the opening paragraph, magnetic means are provided between the first closure part and the second closure part, which are designed to assist the attachment of the first closure part and the second closure part by providing a magnetic attraction force.
  • The present closure device provides two closure parts in each case an engagement projection with undercut and in particular rigid can be arranged on a base body of the respectively associated closure part. These engagement projections are engaged with each other to close the shutter device, for which purpose the engagement projections have to be moved past each other until the first engagement projection can be positively slid into engagement with the second engagement projection in the engagement direction. In the closed position, the engagement projections provide a firm hold of the closure parts together, so that the closure device can be highly loaded without the closure parts separating from each other.
  • In order to exclude an undesired release of the closure parts from each other in the closed position, a blocking element is additionally provided, which is designed, for example, as an elastic spring tongue arranged on a base body of the second closure part or as a blocking part arranged resiliently on the base body. The locking member deviates in attaching the first closure member to the second closure member such that the first engagement projection of the first closure member can be slid in the engagement direction into engagement with the second engagement projection of the second closure member. When fitting the locking element is thus pushed aside so that the first engagement projection can be guided in engagement with the second engagement projection. During or after production of the engagement, the blocking element returns to its basic position and locks in this basic position the positive engagement of the first engagement projection with the second engagement projection against the engagement direction. The retention of the first engagement projection on the second engagement projection and thus of the first closure part on the second closure part is thus secured, so that the closure device can not be inadvertently opened.
  • In addition, magnetic means are provided, for example in the form of a magnet on the first closure part and a magnet on the second closure part or in the form of a magnet on one of the closure parts and a magnetic armature in the form of a component made of a ferromagnetic material on the other of the closure parts are formed. The magnetic means act between the first closure member and the second closure member by cooperating magnetically attractively upon attachment of the first closure member to the second closure member and thus the first closure member is magnetically supported in engagement with the second closure member is pulled.
  • The magnetic means may in this case be advantageously dimensioned such that the engagement of the first engagement projection with the second engagement projection when applying the Closing parts to each other as far as possible is automatically produced and in particular the avoidance of the locking element when attaching the closure parts to each other in a magnetically assisted manner largely automatically. In this way, an easy-to-close closure is provided, in which the closure parts have to be attached to each other only in a relatively imprecise manner to each other and the actual closure of the closure then largely runs automatically in a magnetically assisted manner.
  • Advantageously, the engagement direction corresponds to a load direction in which, when the closure device is used as intended, a load acts between the closure parts. In particular, in a loaded condition, a load is advantageously applied to the first closure member which pulls the first engagement projection into engagement with the second engagement projection or loads the first engagement projection at least in the engagement direction so that the engagement projection is securely held in engagement with the second engagement projection ,
  • The blocking element can be realized, for example, by a locking tongue arranged on a basic body of the second closure part, which is designed to elastically escape from its basic position when the first closure part is attached to the second closure part in a direction transverse to the engagement direction and returns again during or after the engagement to return to their basic position. The locking tongue is advantageously formed integrally with the base body, for example, produced as a plastic injection molded part, extends in particular in the engagement direction and is designed to be elastically resilient in a direction transverse to the engagement direction. To close the closure device, the first engagement projection or a locking lug provided on the first closure part can be guided along the locking tongue and act on the locking tongue in such a way that the locking tongue is urged resiliently in the direction in which it is elastically configured, such that the first engagement projection is engageable with the second engagement projection. Once the engagement has been made, the locking tongue returns to its basic position in which it blocks the engagement of the first engagement projection with the second engagement projection by acting on the first engagement projection or on a locking lug configured separately on the first closure part. In the direction of engagement, the blocking element is in this case rigid, so not elastic designed, so that the engagement is effectively locked and in particular a movement of the first engagement projection against the engagement direction from the second engagement projection is not readily possible.
  • The blocking element may be configured such that it returns to its basic position when the engagement is made or only after the engagement between the first engagement projection and the second engagement projection is established. For example, the locking element may snap back to its home position as soon as the engagement is made (that is, after engagement fabrication). However, it is also possible that, already during engagement production, the blocking element causes a bias on the first closure part due to its elastic configuration, which presses the first engagement projection in the engagement direction into engagement with the second engagement projection and thus already assists the engagement during the manufacture of the engagement.
  • In the closed position, the first engagement projection of the first closure part is in form-locking engagement with the second engagement projection of the second closure part. In this case, this engagement is blocked by the blocking element in that the blocking element prevents the first closure part and thus also the first engagement projection from moving in the direction of engagement, so that the first engagement projection can not be brought out of engagement with the second engagement projection counter to the engagement direction. To open the closure device, either this blockage can be canceled, wherein different actuation variants for opening are conceivable and possible, or the first engagement projection and the second engagement projection can be disengaged without a separate cancellation of this blockage being necessary.
  • In a first variant, the closure device may comprise an actuating device which is designed to act upon actuation of the blocking element in order to lift the blocking of the engagement between the first engagement projection and the second engagement projection by moving the blocking element from a basic position. By actuating the actuating device, the blocking element is thus pushed aside, so that the path for the first engagement projection or for a locking lug against the engagement direction is released from the second engagement projection and thus the first closure part can be removed from the second closure part.
  • In particular, the actuator may be e.g. be an integral with the locking element executed handle or a separate, movable operating part.
  • In a second variant, an actuating device for opening the closure device can be provided, which is designed to move, when actuated, a locking lug arranged on the first closure part with which the blocking element cooperates in the closed position to block the blocking of the locking lug by moving the blocking lug Canceling engagement between the first engagement projection and the second engagement projection. Thus, not the locking element is moved, but a locking lug on the first closure member, which is moved out of the region of the locking element to cancel the blocking of the movement of the first closure member against the engagement direction relative to the second closure member. By movement of the locking lug thus the movement of the first closure member against the engagement direction is released relative to the second closure member, so that the first closure member can be removed from the second closure member.
  • For example, the actuating device may comprise a lever element, which is arranged pivotably about a pivot axis on the base body of the first closure part. On the lever element, one or more locking engagement elements, in particular in the form of projections in the manner of locking lugs, which are in the closed position lockingly engaged with the locking element on the second closure part and thus the engagement between the first Eingriffsvorspruch the first closure part and the Lock second engagement projection of the second closure member against the direction of engagement. By moving the lever member together with the locking engagement members disposed thereon, the lock can be released by moving the lock engagement members out of their locking position relative to the locking member of the second closure member. By actuating the lever element, the blocking between the first closure part and the second closure part can thus be canceled, so that the first closure part can be moved counter to the engagement direction relative to the second closure part and thus released from the second closure part.
  • The lever element may for example be formed of metal, in particular of a ferromagnetic sheet. This has the advantage that after actuation of the lever element, the lever element can be automatically moved back into an initial position due to the magnetic effect of a magnet arranged on the first closure part, so that the first closure part can in turn be attached to the second closure part for closing the closure device.
  • Additionally or alternatively, it is also conceivable to provide a mechanical spring for biasing the lever element relative to the main body of the first closure part.
  • In an advantageous embodiment, a lever portion is provided on the lever element, which occurs during pivoting of the lever element for opening the closure device in operative connection with the second closure part and a force against the Engagement direction causes the first closure member relative to the second closure member. By means of this lever portion of the opening operation can thus be supported by not only the blocking between the at least one locking engagement element of the lever member and the locking element of the second closure member is released upon actuation of the lever member for opening the closure device, but in addition a force between the closure parts is effected which brings the first closure part and the second closure part out of engagement from each other. For this purpose, upon actuation of the lever element for opening the closure device, the lever section can dip, for example, into an opening in the main body of the second closure part and come into abutment with an edge section of this opening, so that the first closure part is displaced counter to the engagement direction relative to the second closure part.
  • The lever portion of the lever member may also serve to bring about when setting the first closure member to the second closure member, a reset of the lever member to its original position in which the at least one locking engagement element on the lever element in locking engagement with the locking element of the second closure member.
  • A closure device with such an actuating device on the first closure part can in principle also be formed purely mechanically, ie without magnetic means arranged on the first closure part and the second closure part. Such a closure device for detachable connection of two parts can generally have, for example, the following features:
    • a first closure part and a second closure part, wherein the first closure part can be attached to the second closure part in order to close the closure device and is held on the second closure part in a closed position,
    • a first engagement projection of the first closure member and a second engagement projection of the second closure member, wherein the first engagement projection is engageable to close in an engagement direction with the second engagement projection and in the closed position is positively engaged with the second engagement projection;
    • a lock member disposed on the second lock member, which is moved out of a home position upon engagement of the first lock member with the second lock member by cooperating with the first lock member such that the first engagement projection is engageable with the second engagement projection in the engagement direction, and at or after the engagement has been brought back into its basic position, in the basic position the positive engagement of the lock first engagement projection with the second engagement projection against the engagement direction, and
    • an operating device for opening the closure device, which is designed, upon actuation, to move a locking engagement element arranged on the first closure part with which the blocking element cooperates in the closed position to block the engagement between the first engagement projection and the second one by moving the locking engagement element Cancel engagement projection, wherein the actuating device has a pivotable about a pivot axis arranged on a base body of the first closure member lever member on which at least one locking engagement element is arranged for cooperation with the locking element in the closed position.
  • In a third variant, in order to open the closure device, the first closure part as a whole or a part of the first closure part can be moved relative to the second closure part in order to block the engagement between the first engagement projection and the second engagement projection and / or the positive engagement between the first engagement projection and to cancel the second engagement projection. Thus, by moving the first closure member relative to the second closure member, the blocking of the movement of the first closure member against the engagement direction can be removed by moving a locking lug on the first closure member or the engagement projection out of the area of the blocking member by moving the first closure member in this way release movement against the direction of engagement. However, it is also conceivable that by moving the first closure part or the part of the first closure part, the first engagement projection is tangentially moved by displacement, rotation or pivoting out of engagement with the second engagement projection, so that the movement of the engagement of the first engagement projection with the second Engaging projection is canceled. Once the procedure has been lifted, the closure parts can be removed from each other. Also conceivable here is a combination such that both the blocking and the engagement are canceled by moving the first closure part or the part of the first closure part.
  • The movement of the first closure part or of the part of the first closure part for opening the closure device can take place linearly along a straight-line path or else by twisting. In particular, in the first variants, different types of actuators, such as actuation buttons or actuation slide, conceivable and possible. If a plurality of locking lugs are provided on the first closure part, in particular also a plurality of actuating devices are independent of each other can be operated to each affect an associated blocking element or a Sperrnasse possible.
  • An actuating direction, in which the actuating device is for actuating, for example, be directed transversely to the direction of engagement. It is also conceivable, however, for the actuating device to be actuated in an actuating direction which is directed along the direction of engagement (in the direction of engagement or against the direction of engagement). The direction of actuation should be chosen so as to provide a comfortable, application-adapted, user-friendly operation. If the first closure part or part of the first closure part is moved relative to the second closure part in order to open the closure device, it can be provided in another embodiment that a ramp is arranged on the first closure part and / or on the second closure part in that, when moving the first closure part or the part of the first closure part, the first closure part and the second closure part run along the ramp, so that the first closure part is separated from the second closure part in a direction perpendicular to the engagement direction. In particular, the separation can take place counter to a closing direction into which the first closure part for closing the closure device is to be attached approximately to the second closure part. In this closing direction, the magnetic means act attractive, so that at the same time removal of the magnetic means from each other and thus a weakening of the acting magnetic forces is effected by the supported by the ramp separation of the closure parts when opening. This supports a simple, easy, comfortable opening of the closure device.
  • The locking member locks in the closed position, the engagement of the first engagement projection with the second engagement projection, so that the first engagement projection can not be readily brought against the engagement direction disengaged from the second engagement projection. In this case, it can be provided that the blocking element, when a limit force acting on the first closure part counter to the engagement direction is exceeded, cancels the position of the engagement between the first engagement projection and the second engagement projection. For example, this may be provided on the blocking element a slight bevel, which causes when exceeding the limit force that a locking lug or the first engagement projection of the first closure part runs onto the locking element and pushes it aside, so that the first engagement projection against the engagement direction disengaged from the second engagement projection can be brought. The blocking element thus blocks the engagement only in a counter to the direction of engagement directed force, the below the limit force. If the limit force is exceeded, the blocking element is pushed aside, so that the closure device can be opened.
  • Advantageously, the first closure part or / and the second closure part has a run-on slope which is such that when the first closure part is attached to the second closure part in a closing direction different from the engagement direction, the first engagement projection runs onto the second engagement projection and opposes the first closure part the engagement direction is urged until the first engagement projection is engageable with the second engagement projection in the engagement direction. The closing direction is directed, for example, transversely to the direction of engagement. The ramp describes an inclined plane that is at an angle between z. B. 30 ° to 60 °, in particular 45 ° (based on the surface normal of the inclined plane) is directed to the closing direction and the engagement direction. Such a ramp facilitates the attachment of the closure parts together. In particular, when the engagement protrusions are formed as rigid members on a base body of the closure members, the engagement protrusions must be moved past each other for engagement, and it is also necessary to move the first engagement protrusion undercut against the engagement direction far enough relative to the second engagement protrusion. in that the engagement projections with undercut can be brought into engagement with one another. This movement against the direction of engagement is assisted by the ramp on which the closure members slide along each other until the engagement projections are engageable with each other.
  • The ability to close the closure device in a direction deviating from the direction of engagement closing direction is very beneficial in daily use. In the from the DE 43 12 032 C2 For example, known pin closure and engagement recess must be relatively precisely manually engaged in the direction of engagement, which may be difficult in the dark, for example.
    The magnetic means may advantageously be formed by a first magnet of the first closure part and a second magnet of the second closure part. The magnets are advantageously arranged on the closure parts such that they magnetically attract when the first closure part is attached to the second closure part, wherein the first magnet and the second magnet are offset in the closed position - viewed along the engagement direction - such that in the closed position, a magnetic attraction acts on the first closure member in the engagement direction. The magnetic means thus cause a bias between the closure members, which tries to pull the first engagement projection in the engagement direction into engagement with the second engagement projection, and thus magnetically assisting the engagement and also the retention of the first engagement projection in the second engagement projection. Viewed along the engagement direction, the magnet of the first closure part is thus arranged in front of the magnet of the second closure part, so that the magnetic attraction between the magnets has at least one force component in the engagement direction.
  • Basically, the magnetic means act magnetically attracting in a closing direction, which may be directed for example approximately perpendicular to the direction of engagement. Due to the action of the magnetic means, the closure members are thus attracted to each other when being applied in the closing direction, wherein the force action between the magnetic means is such that the first engagement projection of the first closure member is magnetically assisted with the second engagement projection of the second closure member and thus the closing of the closure device in a magnetically assisted manner is largely automatic.
  • The first engagement projection on the first closure part and the second engagement projection on the second closure part are advantageously shaped and arranged in such a way that reinforcement of the engagement results when the closure device is loaded. For example, two engagement projections may be provided on the first closure part and the second closure part, each extending at an acute angle to each other, so that a V-shape results. In this case, the tip of the Vs points in the engagement direction, which preferably also corresponds to the loading direction, so that in the loaded state the grip of the engagement projections of the first closure part in the engagement projections of the second closure part is reinforced.
  • In addition, the V-shape is also advantageous with regard to two further aspects. First, by the V-shaped arrangement, forces deviating from the loading direction within an angle given by the V-shape are advantageously absorbed by the positive engagement between the first engaging projections and the second engaging projections. Second, the V-shape stabilizes such that pivotal forces acting on the closure in the closed position about the closing direction can be absorbed on a comparatively large effective width (compared to the depth of the engaging projections). The effective width here is approximately the width of the V-shaped engagement projections in the loading direction.
  • In principle, however, other shapes of the engagement projections on the first closure part and the second closure part are also conceivable. For example, the first engagement projection and the second engagement projection may each be designed arcuate.
  • The V-shape or arch shape also has the advantage that V-shaped or arcuate engagement protrusions may have improved stability over a simple linear engagement protrusion.
  • It is also conceivable and possible that a plurality of engagement projections are arranged on each closure part, which are offset from each other along the engagement direction. The engagement projections may in this case be arranged in the manner of a row or in the manner of a matrix on the respective closure part, so that a plurality of engagement projections are brought into engagement with each other for closing. The number of blocking elements here does not have to correspond to the number of engaging projections. In principle, a single blocking element for blocking the movement of the first closure part counter to the direction of engagement relative to the second closure part is sufficient. Advantageously, however, it is also possible for a plurality of blocking elements to be present.
  • Engagement projections may also be arranged, for example, periodically or in groups on the closure parts, so that the closure parts can be brought into engagement with one another in different closed positions. In particular, the engagement protrusions may also be realized by groups of V-shaped or arcuate engagement protrusions arranged in the manner of a row or matrix.
  • The advantageous reinforcement of the positive engagement of the engagement projections under a load in the loading direction is a significant functional difference to a conventional buckle, as it is known in a variety of variants for application, among other things to backpacks. The principle of the buckle is precisely defined by the fact that two closure parts in an insertion direction, which is opposite to a direction of loading, are attached to each other. This means that the load capacity of such a closure depends on the stability of necessarily resiliently designed latching elements. In contrast, a closure, in which advantageously the loading direction reinforces the form-locking of two, in particular, rigid engagement sections, offers great safety and high load-bearing capacity. Such a closure is therefore well suited for safety-relevant applications such as helmet caps or seat belts especially for child seats or strollers not only from a technical but also from a user-psychological point of view.
  • In an advantageous embodiment, the first closure part and the second closure part are identical. This results in a particularly simple manufacturability with only one tool, for example by means of plastic injection molding, wherein for closing the closure parts are mirror images of each other and the first engagement projection of the first closure member is brought into engagement with the second engagement projection of the second closure member.
  • In a further embodiment, the first closure part and / or the second closure part is arranged such that it can be sunk down on a housing such that the closure part is at least partially enclosed by the housing in a lowered position and when the first closure part is attached to the second closure part for establishing the engagement between the first engagement projection and the second engagement projection is extended from its retracted position. In the retracted position, the respective closure part is thus at least partially sunk in the housing, so that in particular the engagement projection does not or only partially protrudes outwards. In order to establish the connection of the closure parts, when the closure parts are applied to one another, in particular by the action of the magnetic means between the closure parts, the closure part is extended, so that in the extended position the engagement between the engagement projections is established and the closure device can thus be closed.
  • This is particularly advantageous when it is required that objects are to be brought into positive engagement, which have no disturbing outwardly projecting hooks with the shutter open.
  • The object is also achieved by a buckle for connecting two loaded on train along a load direction straps. Such a buckle comprises
    • a first closure part and a second closure part, wherein the first closure part can be attached to the second closure part in order to close the closure device and is held on the second closure part in a closed position,
    • a first engagement projection of the first closure member and a second engagement projection of the second closure member, the first engagement projection being engageable with the second engagement projection for closing in an engagement direction and being positively engaged with the second engagement projection in the closed position, and
    • a lock member disposed on the second lock member, which is moved from a home position upon engagement of the first lock member to the second lock member by cooperation with the first lock member such that the first engagement projection is engageable with the second engagement projection in the engagement direction; after the engagement has been brought back into its basic position in order to block in the initial position the positive engagement of the first engagement projection with the second engagement projection against the direction of engagement.
  • It is further provided that at the first closure part and / or the second closure part, a Gurtbandaufnahme is arranged for fastening a belt and in a loaded state load forces along a load direction on the closure parts act such that the first closure member in the direction of engagement relative to the second Locking part is charged.
  • Purely functionally corresponds to the buckle of the closure device described above, wherein the buckle can also be configured as a purely mechanical, non-magnetic closure device. Advantageously, however, magnetic means for assisting the closing operation may also be present in the buckle, so that the above-described also applies to the buckle.
  • The buckle is a closure device in which by (releasable) connection of the closure parts to train straps to be loaded are interconnected. The load direction is in this case directed along the engagement direction, so that when pulling the straps of the hold of the closure parts is reinforced and thus the buckle can not be opened easily in the loaded state. The engagement of the closure parts is in this case additionally secured by the blocking element, so that inadvertent release in the loaded or unloaded state is not readily possible.

  • A first embodiment of a closure device 1 is shown in FIG Fig. 1A and 1B such as FIGS. 2A and 2B shown in different perspective views. The closure device 1 has a first closure part 2 and a second closure part 3, which can be attached to each other for closing the closure device 1 in approximately a closing direction X. In a closed position, engagement protrusions 220, 221 of the first closure part 2 mechanically engage with engagement protrusions 320, 321 of the second closure part 3, so that the closure parts 2, 3 are held together by means of the engagement protrusions 220, 221, 320, 321.
  • The first closure part 2 has a main body 20, on which a webbing receptacle 21 is designed for fastening a belt. On the first closure part 2, an engagement means 22 is formed, which is essentially formed by two engagement projections 220, 221, which each extend in a straight line and together form a V-shape. The engagement projections 220, 221 are each formed in the manner of undercuts.
  • The second closure part 3 also has a base body 30 to which a webbing receptacle 31 for attaching a belt is attached. On the second base body 30, an engagement means 32 is formed, the engagement projections 320, 321 which are also formed in the manner of undercuts and in the closed position with the engagement projections 220, 221 of the first closure part 2 are engaged.
  • On the first closure part 2, two locking lugs 23, 24 are formed which project from the latching projections 220, 221 and serve to cooperate with locking elements 33, 34 of the second closure part 3 for locking the closure device 1 in its closed position. The locking elements 33, 34 are formed as elastic locking tongues on the base body 30 of the second closure part 3 and extend tongue-like along an engagement direction Y (see, for example Fig. 1A, 1B and Fig. 5D ) into which the first closure part 2 with its engagement projections 220, 221 is to be brought into engagement with the second closure part 3 with its engagement projections 320, 321.
  • On the second closure part 3, an actuating device 4 in the form of an actuating slide is provided, which is displaceable along the engagement direction Y on the base body 30 and for this purpose the base body 30 with a holding element 41 surrounds (see, eg Fig. 2B ). The actuating device 4 in the form of the actuating slide has actuating lugs 42, 43 which serve to cooperate with the blocking elements 33, 34 in order to actuate the blocking elements 33, 34 for unlocking the closure device 1. The actuation lugs 42, 43 can accumulate on run-up slopes 330, 340 of the locking elements 33, 34 for this purpose, as will be described below. On the actuating device 4 in the form of the actuating slide further guide elements 44 are provided, via which the actuating device 4 is guided on the main body 30 of the second closure part 3.
  • The operation of the closure device 1 will be described below with reference to Fig. 3A to 3G . 4A to 4G and 5A to 5G be explained. Fig. 3A to 3G show top views of the closure device 1, FIGS. 4A to 4G show sectional views along the line CC according to Figs. 3A to 3G and Figs. 5A to 5G show sectional views along the line DD according to Fig. 3A to 3G , The closure device is shown in different positions in the figures, with the figures labeled "A", "B", "C", etc., each representing the same positions.
  • In a starting position, shown in 3A, 4A and 5A , the closure parts 2, 3 are separated from each other. For closing the shutter, the first shutter 2 is attached to the second shutter 3 in a closing direction X, thereby mechanically engaging the engaging protrusions 220, 221, 320, 321 and their shutter parts 2, 3.
  • To assist in setting up and establishing the connection of the closure parts 2, 3, magnets 25, 35 are arranged on the closure parts 2, 3, which, as is apparent from the sectional view according to FIG Fig. 4A assign, with unlike poles on each other, so that a magnetic attraction between the closure parts 2, 3 is effected.
  • When the closure members 2, 3 are fitted to each other in the closing direction X, the engagement projections 220, 221 of the first closure member 2 and the engagement projections 320, 321 of the second closure member 3 with chamfers 222, 322 abut on the engagement projections 220, 221, 320, 321 so that the first closure part 2 is set back against the engagement direction Y with respect to the second closure part 3 until the engagement projections 220, 221 of the first closure part 2 against the engagement projections 320, 321 of the second closure part 3 have passed and the first closure part 2 with its engagement projections 220, 221 in the engagement direction Y can be brought into engagement with the engagement projections 320, 321 of the second closure part 3. This is in Fig.3B, 4B, 5B and 3C, 4C and 5C shown.
  • When the engagement projections 220, 221, 320, 321 have been moved past each other, the second closure member 2 can be displaced in the engagement direction Y toward the second closure member 3 until the engagement projections 220, 221 of the first closure member 2 engage with the engagement projections 320, 321 of the first closure member second closure part 3 are engaged, as in FIGS. 3D, 4D and 5D is shown. When attaching the first closure part 2 to the second closure part 3, the first closure part 2 acts with its locking lugs 23, 24 on the respectively associated locking elements 33, 34, which are deflected elastically from its basic position as a result of Ansetzens and accordingly in a direction transverse to the direction of engagement Y dodge, like this Fig. 5C is apparent. In the closed position, shown in Fig. 5D , the locking lugs 23, 24 are slid along the locking elements 33, 34 and now engage in an opening 341 formed in the engagement direction Y beyond the respectively associated locking element 33, 34. By means of the locking elements 33, 34 which are rigidly formed counter to the engagement direction Y, the engagement of the engagement projections 220, 221 of the first closure part 2 in the engagement projections 320, 321 of the second closure part 3 is thus locked, so that the second closure part 2 is not readily can be moved relative to the engagement direction Y relative to the second closure part 3 and thus the first closure part 2 can not be easily detached from the second closure part 3.
  • When the closure device 1 is loaded as intended in the closed position, forces act along a load direction F between the closure parts 2, 3 (see FIG Fig. 5D ), which can be reliably and resiliently received by the engagement of the engagement projections 220, 221, 320, 321. By means of the locking elements 33, 34 which cooperate with the locking lugs 23, 24, the closure device 1 is additionally secured against unintentional opening.
  • How out Fig. 4D can be seen, the magnets 25, 35 are arranged on the closure parts 2, 3, that they still have an offset along the engagement direction Y to each other in the closed position. Thus, the magnet 35 of the second closure part 3 is arranged along the engagement direction Y behind the magnet 25 of the first closure part 2, so that even in the closed position a magnetic attraction with a component in the engagement direction Y between the closure parts 2, 3 is effected, which results in the first closure part 2 being loaded in the engagement direction Y relative to the second closure part 3 in the closed position, and thus on the one hand the transfer of the first closure part 2 into the closed position and also the maintenance of the first closure part 2 on the second closure part 3 magnetically supported.
  • In order to open the closure device 1, the actuating device 4 is actuated in the form of the actuating slide by the actuating slide 4 is displaced in an operating direction B rectified in the direction of engagement Y relative to the main body 30 of the second closure part 3, as in FIGS. 3E, 4E and 5E is shown. As a result, the operating lugs 42, 43 of the actuating slide 4 run on the ramps 330, 340 of the associated locking elements 33, 34, so that the locking elements 33, 34 are pushed aside transversely to the engagement direction Y, as shown in Fig. 5E is shown. The locking lugs 23, 24 are thus released, and the closure device 1 is unlocked, so that the closure parts 2, 3 can be detached from each other, as in Figs. 3F, 4F, 5F and 3G, 4G, 5G is shown.
  • This embodiment of the actuator is particularly advantageous because a user can perform the two necessary for opening operations (lifting the blocking by the locking piece and canceling the engagement of the engaging projections) with an operation.
  • The closure parts 2, 3 can be designed, for example, in a simple production as plastic injection molded parts. The magnets 25, 35 are attached in this case as additional components, for example formed as neodymium magnets, to the closure parts 2, 3.
  • In principle, the magnets 25, 35 can also be dispensed with in order to provide a purely mechanical closure device 1. In this case, the closure parts 2, 3 are manually attached to each other and bring into engagement with each other.
  • In Fig. 6A . 6B such as Figs. 7A to 7F . 8A-8F and 9A-9F is a further embodiment of a closure device 1 is shown. This closure device 1 has a first closure part 2 and a second closure part 3, each having a base body 20, 30 on which engagement projections 220, 221, 320, 321 are formed. Each closure part 2, 3 carries a Gurtbandaufnahme 21, 31. At the second closure part 3 locking elements 33, 34 are arranged.
  • The operation of the closure device is similar to the previous embodiment, so that reference should be made to the above. In contrast to the embodiment described above, however, an actuating device 4 with two actuating parts 40A, 40B is provided in this embodiment, which are connected to each other via a spring element 45. The actuating device 4 may be designed, for example, in one piece as a plastic part. The actuating device 4 is arranged in a receiving space 200 on the first closure part 2 and is held in the receiving frame 200 via a housing cover 201. (The housing cover 201 is for easy overview in Figs. 7A-7F . 8A-8F and 9A-9F not shown). On each actuating part 40A, 40B a locking lug 400A, 400B is arranged, which in each case passes through a gap 200A, 200B on the main body 20 of the first closure part 2.
  • The operation of the closure device 1 results from Figs. 7A-7F . 8A-8F and 9A-9F in which the closure device 1 is shown in different positions.
  • For closing, the closure parts 2, 3 are attached to each other in a closing direction X, whereby run-up slopes 222, 322 run against each other on the engagement projections 220, 221, 320, 321 and, analogously as described above, the engagement projections 220, 221, 320, 321 abut each other move past (s. Figs. 7A, 8A, 9A ).
  • When attaching the locking lug 400A, 400B, which are in the preparation - due to a caused by the spring member 45, the actuating members 40A, 40B pushing away from each other biasing - in an outer position in the respective associated gap 200A, 200B meet the blocking elements 33rd , 34, so that they are pushed out of their rest position ( Figs. 7B, 8B, 9B ).
  • When the engagement protrusions 220, 221 of the first closure part have passed the engagement protrusions 320, 321 of the second closure part 3 in the closing direction X, the engagement protrusions 220, 221 can be brought into engagement with the engagement protrusions 320, 321 of the second closure part 2 (FIG. Figs. 7C, 8C, 9C ).
  • In the closed position, the engagement projections 220, 221 of the first closure part 2 engage in the engagement projections 320, 321 of the second closure part 3, so that the first closure part 2 is mechanically held on the second closure part 3.
  • As the second closure member is moved in the direction of engagement Y relative to the second closure member 3 for engaging the engagement projections 220, 221, 320, 321, the locking tabs 400A, 400B also move along the respective associated locking members 33, 34. In the closed position, the locking tabs 400A , 400B then in openings 331, 341 beyond the blocking elements 33, 34 (see Fig. 8C ), so that the closure device 1 is locked by means of the locking lugs 400A, 400B and the cooperating with these locking elements 33, 34 and thus the engagement of the engagement projections 220, 221, 320, 321 is secured together.
  • If the closure device 1 is to be opened, then the actuation parts 40A, 40B of the actuation device 4 are pressed toward one another in an actuation direction B (FIG. Figs. 7D, 8D, 9D ). As a result, the locking lugs 400A, 400B arranged on the actuating parts 40A, 40B are moved transversely to the input direction Y out of the region of the blocking elements 33, 34 ( Fig. 9D ), so that the first closure part 2 with the engagement projections 220, 221 arranged thereon can be moved counter to the engagement direction Y relative to the second closure part 3, without this movement being blocked by the blocking elements 33, 34.
  • By the locking lugs 400A, 400B in the associated columns 200A, 200B further pressed towards each other (in the direction of actuation B, see Figs. 7E, 8E, 9E ), the locking lugs 400A, 400B act in the operating direction B on the V-shaped engagement projections 320, 321 of the second closure member 2 and push the first closure member 2 against the engagement direction Y of the second closure member 3 away, so that the release of the closure parts 2, 3 is mechanically supported one another.
  • After unlocking the device and releasing the closure parts 2, 3 from each other, the first closure part 2 can be removed from the second closure part 3 ( Figs. 7F, 8F, 9F ).
  • In the illustrated embodiment, magnetic means 25, 35 are again provided, which magnetically support the attachment of the closure parts 2, 3 to each other in the closing direction X. Reference is made to the comments on the first embodiment according to Fig. 1-5 directed.
  • In the case of Fig. 6-9 described embodiment, the actuator 4 is formed with two separate, independently operable actuators 40A, 40B. These need to open the closure device 1 are moved toward each other along an actuating direction B transverse to the closing direction X and transversely to the direction of engagement Y, thus bringing the locking lugs 400A, 400B out of their blocking position relative to the blocking elements 33, 34.
  • In a further embodiment of a closure device 1, shown in FIG Fig. 10A . 10B such as Figs. 11A-11C and 12A-12C , a first closure part 2 has a first engagement projection 220 and a second closure part 3 has a second engagement projection 320. In addition, a blocking element 33 in the form of a spring tongue, which is connected elastically resiliently to a base body 30 of the second closure part 3, is arranged on a second closure part 3.
  • The operation of the closure device 1 results from Figs. 11A-11C and 12A-12C showing the closure device 1 in different positions.
  • While closing ( Fig. 11A, 12A ), the first closure member 2 is attached in a closing direction X to the second closure member 3, wherein the engagement projections 220, 320 accumulate with run-on slope and thus the first closure member 2 against an engagement direction Y (perpendicular to the closing direction X) is added to the second closure member 3 , In this case, the first engagement projection 220 of the first closure part 2 also acts on the blocking element 33 of the second closure part 3, so that the blocking element 33 deviates approximately in the closing direction X and thus the engagement projection 220 of the first closure part 2 with the input projection 320 of the second closure part 3 can be engaged.
  • Magnets 25, 35 are magnetically supported on the first closure part 2 and the second closure part 3 and magnetically support the attachment of the closure parts 2, 3 to each other and provide a magnetic attraction force for this purpose.
  • In the closed position ( Fig. 11B, 12B ), the engagement projection 220 of the first closure member 2 is positively engaged with the engagement projection 320 of the second closure member 3, as shown in FIG Fig. 12B is shown. In the closed position, the blocking element 33 assumes its basic position in which the blocking element 33 extends along the engagement direction Y and blocks the first engagement projection 220 of the first closure part 2 from moving counter to the engagement direction Y. The engagement projection 220 engages in this case in an opening 331 on the side of the free end of the locking element 33 a.
  • For opening, the first closure part 2 can be displaced into a recess 332 of the second closure part 3 in an opening direction Z directed transversely to the closing direction X and transversely to the engagement direction Y, such that the engagement projection 220 of the first closure part 2 is removed from the area of the blocking element 33 and simultaneously the engagement projection 220 is moved out of engagement with the engagement projection 320. The engagement projection 320 of the second closure part 3 slides in a groove-shaped recess 224 of the first closure part 2 (FIG. Fig. 10A ), so that the engagement projections 220, 320 mutually disengage.
  • As a result of the opening movement of the first closure part 2 in the opening direction Z, the blocking by the blocking element 33 is thus released on the one hand by the engagement projection 220 being removed from the area of the blocking element 33. On the other hand, the engagement between the engagement projections 220, 320 is released, so that the first closure part 2 can be removed not only against the opening direction Y, but also directly opposite to the closing direction X from the second closure part 3.
  • In principle, it is also conceivable that by displacing the second closure part 2 in the opening direction Z only the blocking or only the engagement of the engagement projections 220, 320 is canceled. In the first case, the engagement projection 320 would extend along the entire width of the recess 332. In the second case, the blocking element 33 would extend along the entire width of the recess 332.
  • The operation of the closure device 1 is otherwise similar to the two embodiments described above, so that reference should also be made in the supplement to the above.
  • At another, in FIGS. 13A, 13B such as Figs. 14A-14E and Figs. 15A-15E 1, a closure device 1 has a first closure part 2 and a second closure part 3, each having two engagement projections 220, 221, 320, 321, each of which describes circular arc sections.
  • The first closure part 2 has a pin receptacle 26 into which a pin 36 of the second closure part 3 is inserted when closing the closure device 1. One of the engagement protrusions 220 of the first closure member 2 is disposed inside the trunnion receiver 26, while the other of the engagement protrusions 221 is located on an outer wall of the trunnion receiver 26.
  • The second closure part 3 has a blocking element 33, which is designed as an elastic locking tongue on a base body 30 of the second closure part 3.
  • The operation of the closure device 1 results from Figs. 14A-14E such as Figs. 15A-15E ,
  • For closing, the first closure part 2 is attached in a closing direction X to the second closure part 3. In this case, the engagement projections 220, 221 each run into the associated engagement projections 320, 321 of the second closure part 3 with run-on slopes, so that the first closure part 2 is displaced counter to the engagement direction Y relative to the second closure part 3 (FIG. Figs. 14A, 15A ).
  • When fitting, an engagement projection 220 of the two engagement projections 220, 221 of the first closure part 2 also comes into abutment with the blocking element 33 and pushes this out in the closing direction X from its basic position (FIG. Figs. 14B, 15B ) until the engagement projections 220, 221 engage with each other in the engagement direction Y ( Figs. 14C, 15C and Figs. 14D, 15D ). In the closed position ( Figs. 14D, 15D ), the engaging projections 220, 221, 320, 321 are positively engaged with each other, the engagement of the in Fig. 15D On the left, the engagement projection 220 of the first closure part 2 is secured against the engagement direction Y by the blocking element 33.
  • Like, for example Fig. 15C it can be seen, the locking element 33 is elastically bent during application of the first closure part 2 to the second closure part 3 and thereby biased. This biasing force thereby acts on the engagement projection 220 at least with a force component in the engagement direction Y, so that the contact surfaces between the blocking element 33 and the engagement projection 220 in the prestressed state are no longer parallel but at an angle to each other and engaging the engagement projections 220, 221 in the Engagement direction Y with the engagement projections 320, 321 is supported mechanically due to the spring bias by the blocking element 33. This effect can advantageously be further enhanced in that bevels 333 are provided on the blocking element 33 and / or the engagement projection 220, with which in the prestressed state, the blocking element 33 and the engagement projection 220 abut each other and at least a portion of the bias in one in the Implement direction Y directed force component that supports the engagement.
  • At the closure parts 2, 3, in turn, magnets 25, 35 are arranged, which attract magnetically and support the attachment of the closure parts 2.3 magnetically. For this purpose, reference is also made to the explanations to the preceding embodiments.
  • On the first closure part 2, an actuating device 4 in the form of an elastically connected to a base body 20 of the first closure member 2, integrally formed with the base body 20 actuating element 4 is arranged, which is depressed to open the closure device 1 in a direction along the closing direction X direction of actuation B. in that the actuating element 4 acts on the blocking element 33 and moves it out of a blocking basic position ( Figs. 14E, 15E ). The engagement projection 220 is thus released, so that the first closure part 2 can be moved to the second closure part 3 in a release direction Y 'opposite to the engagement direction Y, and thus the input projections 220, 221, 320, 321 can be disengaged from each other.
  • This is particularly advantageous because a user can perform the two operations necessary for opening (lifting the blocking by the locking piece and canceling the engagement of the engaging projections) with an operation.
  • At another, in FIGS. 16A-16D and 17A-17D and 18A, 18B illustrated embodiment of a closure device 1 are two closure part 2, 3 of identical design to each other and each have two engagement projections 220, 221, 320, 321 on. The fact that the closure parts 2, 3 are formed as identical parts, results in a particularly simple production, because only a tool for producing the closure parts, for example by means of plastic injection molding is required.
  • The closure parts 2, 3 each have a blocking element 27, 33 which, in a closed position of the closure device 1, interacts with an associated engagement projection 320 or 221 of the respective other closure part 3, 2.
  • The operation of the closure device 1 results from FIGS. 16A-16D and 17A-17D ,
  • For closing, the first closure part 2 in the closing direction X is attached to the second closure part 3, whereby the locking elements 27, 33 are moved out of its normal position by cooperation with the engagement projection 320, 221 of the other closure part 3, 2 (see Fig. 17A and 17B ). By the Beideitedrängen the locking elements 27, 33, the engagement projections 220, 221, 320, 321 are engaged with each other by the first closure member 2 is moved in the direction of engagement Y relative to the second closure member 3, until in the closed position ( Fig. 16C, 17C ) the engagement projections 220, 221, 320, 321 are positively engaged with each other. When transferring the engagement projections 220, 221, 320, 321 into the closed position, the blocking elements 27, 33 return to their basic position, in which they block movement of the first closure part 2 against the engagement direction Y relative to the second closure part 3, so that the engagement of the engagement projections 220, 221, 320, 321 against the engagement direction Y is secured.
  • To open the shutter device 1, the first shutter member 2 can be rotated relative to the second shutter member 3 in an operating direction Z, thereby disengaging the engaging projections 220, 221 of the first shutter member 2 in the opening direction Z from the engaging projections 320, 321 of the second shutter member 3 are brought ( Figs. 16D, 17D ). At the same time, the engagement projections 220, 321 come out of the region of the blocking elements 27, 33 in this way, so that the blocking means 27, 33 no longer lock the closure device 1. In the position thus opened, the closure parts 2, 3 can be removed from each other.
  • When opening by turning the first closure part 2 in the opening direction Z relative to the second closure part 3 ramps 280 run on a pedestal 28 of the closure parts 2, 3 on each other (see Fig. 18B in which the first closure part 2 is shown in a separate view; the second closure part 3 is identical). By running the ramps 280 of the closure parts 2, 3 successive the first closure part 2 is opposite to the closing direction X when opening the closure device 1 separated from the second closure part 3, which is advantageous to simultaneously at the same time a weakening of the between the magnets 25, 35 cause the closure parts 2, 3 acting magnetic forces. For opening, the first closure part 2 is rotated approximately at 90 ° relative to the second closure part 3 ( Fig. 16B ). Opening is possible by turning both in the opening direction Z and counter to the opening direction Z, so that the first closure part 2 can be rotated in both directions relative to the second closure part 3.
  • The magnets 25, 35 are advantageously designed as rectangular magnets. As a result, the magnets 25, 35 are aligned on approach so that the closure parts 2, 3 are preferably in the in Figs. 16A-16C, Figs. 17A-17C align shown, aligned position. In a twisting creates a magnetic return torque, especially in a only minor, possibly unintentional deflection the closure parts 2, 3 back into their longitudinal alignment, the closed position corresponding alignment.
  • At another, in Figs. 19A-19F illustrated embodiment of a closure device 1, a first closure part 2 in a closing direction X to a second closure part 3 are recognized. When applying ( Fig. 19A . 19B ) engage engaging projections 220, 320 of the first closure member 2 and the second closure member 3 on each other, so that the engagement projections 220, 320 slide along bevels along each other and the first closure member 2 against an engagement direction Y relative to the second closure member 3 is added. In this case, a blocking element 33 of the second closure part 3 is pushed aside in the closing direction X ( Fig. 19C ) so that the engagement protrusion 220 of the first closure member 2 can be moved past the engagement protrusion 320 of the second closure member 3 until the engagement protrusions 220, 320 can be positively engaged with each other in the engagement direction Y (FIG. Fig. 19D ). In the closed position ( Fig. 19D ), the blocking element 33 is again in its basic position, in which the blocking element 33 acts in a locking manner on the engagement projection 220 of the first closure part 2 and thus secures the engagement of the engagement projections 220, 320 with one another. To open the first closure part 2 can be pivoted together with an object 202 arranged thereon in an opening direction Z. In this case, the engagement projection 220 moves with a rounded portion 223 along an end face of the lock member 33, so that the positive engagement between the engagement projection 220 and the engagement projection 320 against the closing direction X is released and the first closure member against the closing direction X removed from the second closure part 3 can be ( Fig. 19F ).
  • With the in Figs. 19A-19F illustrated embodiment, for example, a pair of glasses (for example, a goggles) or a visor or the like to a helmet (for example, a ski helmet) are attached.
  • At the in Fig. 20 illustrated embodiment of a closure device 1, two identical parts of identical design closure parts 2, 3 each have a plurality of engagement projections 220, 320, which are arranged in series on the respective associated closure part 2, 3. The engagement projections 220, 320 are engaged with each other by fitting the closure members 2, 3 in a closing direction, wherein in the in Fig. 20 illustrated closed position of the maintenance of the engagement projections 220, 320 to each other by two locking elements 27, 33 of the closure parts 2, 3 is secured, so that the engagement of the engagement projections 220, 320 can not be easily canceled.
  • For actuation, the locking elements 27, 33 can be manually operated by being bent out of their locking engagement with the associated engagement projections 320, 220. After moving away the blocking elements 27, 33, the engagement projections 220, 320 can then be moved counter to the direction of engagement Y to each other, so that the closure parts 2, 3 can be separated from each other.
  • In the embodiment according to Fig. 21 are, in modification of the embodiment according to Fig. 20 , in each case a plurality of engagement projections 220, 320 arranged on two closure parts 2, 3 in the manner of a two-dimensional matrix. Again, a locking element 27, 33 is arranged on each closure part 2, 3, so that in the closed position, the engagement of the engagement projections 220, 320 is locked together.
  • Basically, the number of engagement projections 220, 320 on a closure part 2, 3 does not need to match the number of blocking elements 27, 33. Basically, a locking element 27, 33 on a closure part 2, 3 sufficient to lock the engagement of the engagement projections 220, 330 locking, wherein for a secure locking and a plurality of locking elements 27, 33 either on the first closure part 2 or on the second closure part 3 or can be provided on both closure parts 2, 3.
  • At the in Fig. 22A . 22B such as Figs. 23A-23E . 24A - 24E and Figs. 25A-25E illustrated embodiment of a closure device 1, two closure parts 2, 3 are provided, of which a second closure part 3 is arranged to be retractable on a housing 5.
  • A first closure part 2 has engagement projections 220, 221, which are similar to the embodiment according to FIG Fig. 1 to 5 are formed. An actuating device 4 in the form of a pushbutton, which serves to open the closure device 1, is arranged on the first closure part 2. The push button 4 has actuating parts 40A, 40B, which pass through openings 203, 204 on a base body 20 of the first closure part 2 and serve to act on blocking elements 33, 34 of the second closure part 3. The push button 4 has an opening 401, which is in engagement with a magnetic receptacle 250 of the first closure part 3. At the magnet holder 250, a magnet 25 of the first closure part 2 is held.
  • The second closure part 3 also has engagement projections 320, 321. In addition, 3 blocking elements 33, 34 are provided on the second closure part. In that sense, the second is Closure part 3 similar to the second closure part 3 according to the embodiment according to Fig. 1 to 5 ,
  • The second closure part 3 is arranged on a housing 5 and can be displaced in the housing 5 along the closing direction X into which the closure parts 2, 3 can be attached to one another. The housing 5 has a main body 50 with an opening 500, on which a stop 501 for limiting the displacement path of the second closure part 3 is arranged. On the main body 50, a bottom 51 is arranged, on which a magnet 52 is held on a magnet holder 511 (the magnet 52 can also be designed as a ferromagnetic armature).
  • The operation of the closure device 1 will be described below with reference to Figs. 23A-23E . 24A-24E and 25A-25E be explained.
  • In an initial state before closing the closure device 1, the second closure part 3 is in a retracted position within the housing 5 (FIG. Fig. 24A ). In this recessed position, the second closure part 3 is pulled after opening the closure device 1 by the magnet 52 on the bottom 51 of the housing 5 magnetically attractively cooperates with the magnet 35 of the second closure member 3 and thus a magnetic attraction to the second closure member 3 in causes the housing 5 in.
  • If the closure device 1 is to be closed, then the first closure part 2 is brought closer to the housing 5 so that the magnet 25 of the first closure part 2 also approaches the magnet 35 of the second closure part 3. Due to the magnetic attraction between the magnets 25, 35, the second closure part 3 is extended from its retracted position in the housing 5 ( Fig. 24B ), so that the second closure part 3 enters an extended position, in which the first closure part 2 can be brought into engagement with the second closure part 3.
  • The displacement of the second closure part 3 in the housing 5 is limited by the stop 501 on the housing 5 and a stop 37 on the second closure part 3. In the extended position, these stops 501, 37 are in contact with each other, so that the second Closure part 3 is located in a defined position on the housing 5. In this position, at least the engagement projection 320 of the second closure part 3 protrudes from the opening 500 of the housing 5.
  • When the first closure part 2 is attached to the second closure part 3, the engagement projection 220 of the first closure part 2 presses on the blocking element 33 of the second closure part 3 (FIG. Fig. 25B ), so that the blocking element 33 deviates in the closing direction X and the engagement projections 220, 221 of the first closure part 2 engage with the engagement projections 320, 321 ( Figs. 23C, 24C, 25C ).
  • In the closed position ( Figs. 23C, 24C, 25C ) engage the engagement projections 220, 221, 320, 321 then engage each other, wherein the engagement against the engagement direction Y by the locking elements 33, 34 is secured.
  • To open the actuating button 4 is actuated in a direction of closing X rectified actuating direction B, so that actuating parts 40A, 40B act on the respective associated locking elements 33, 34 and push them out of their normal position ( Fig. 25D ). The inhibition of the engagement of the engagement projections 220, 221, 320, 321 is thus canceled, so that the engagement projections 220, 221 can be brought out of engagement with the engagement projections 320, 321 of the second closure part 3 (FIG. Figs. 23E, 24E, 25E ). Out of this state, the closure parts 2, 3 can be released from each other, so that the closure device 1 is opened.
  • At an in Fig. 26A and 26B in two exploded perspective views and in Figs. 27A-27D and 28A-28D shown in different positions embodiment of a closure device 1, two closure parts 2, 3 are provided, which basically in the manner of, for example, based on Fig. 1 to Fig. 5 are each formed and two engagement projections 220, 221, 320, 321, which are V-shaped to each other and in the closed position of the closure device 1 are positively engaged with each other. In this regard, reference should also be made to the preceding description.
  • At the in FIGS. 26 to 28 illustrated embodiment, the first closure part 2 on an actuator 4, which is formed by a lever member 46. The lever element 46 is articulated on two lugs on pins 205, 206 of the base body 20 of the first closure part 2 and about a pivot axis S relative to the base body 20 pivotally. On the lever element 4, two locking lugs 460A, 460B are arranged at a front end remote from the lugs 461 A, 461 B, which engage in the closed position of the closure device 1 with locking elements 33, 34 rigidly formed on the base body 30 of the second closure part 3 stand and in this way lock the positive engagement between the closure parts 2, 3 in the closed position against the engagement direction Y.
  • For attaching the first closure part 2 to the second closure part 3 for closing the closure device 1, the first closure part 2, as in FIG Figs. 27A, 28A represented, in the closing direction X, the second closure part 3 approximated. By magnets 25, 35 on the closure parts 2, 3 (or a magnet on a closure part 2, 3 and a magnetic armature on the other closure part 3, 2), this closing operation is magnetically assisted by the closure parts 2, 3 are magnetically attracted to each other.
  • Meet as in Fig. 27B, 28B shown run-up slopes 222, 322 on the engaging projections 220, 221, 320, 321 on each other and run on each other such that the first closure member 2 is displaced in the opposite direction Y relative to the second closure member 3, so that the first closure member with its engagement projections 220, 221 can slide past the engagement protrusions 320, 321 and engage with the engagement protrusions 320, 321.
  • In the closed position, shown in Figs. 27C, 28C , the engagement projections 220, 221, 320, 321 of the closure parts 2, 3 are positively engaged with each other, so that in particular loads acting in the engagement direction Y between the closure parts 2, 3, can be effectively absorbed.
  • On the main body of the first closure part 2, a web guide 207 is provided which, when the closure parts 2, 3 are engaged, comes into engagement with a groove guide 300 on the base body 30 of the second closure part 3. As a result, the closure parts 2, 3 are defined transversely to the closing direction X and transversely to the engagement direction Y relative to each other, so that a displacement of the closure parts to each other only along the engagement direction Y is possible. The mechanical stability of the closure device 1 is thereby improved.
  • When attaching the closure parts 2, 3 together also meet the locking lugs 460A, 460B on the lever member 46 of the actuator 4 to the rigid locking elements 33, 34 of the second closure member 3. In this case, the lever element 46 initially differs slightly and is pivoted, as in Fig. 28B is pictured. In the closed position, the locking lugs 460A, 460B come to rest in the direction of engagement Y behind the locking elements 33, 34, so that a displacement of the first closure part 2 against the engagement direction Y is locked relative to the second closure part 3, as is apparent from Fig. 28C is apparent. In the Closed position, the closure parts 2, 3 are thus held in the direction of engagement Y positively against each other and locked against the direction of engagement Y relative to each other.
  • To open the lever member 46 is actuated and pivoted thereto in an opening direction Z, as shown in Figs. 27D, 28D is shown. As a result, the locking lugs 460A, 460B reach the lever element 46 from the region of the blocking elements 33, 34 on the second closure part 3, so that the blocking between the closure parts 2, 3 is canceled.
  • In addition, upon actuation of the lever element 46, a lifting section 462 of the lever element 46, which is remote from the locking lugs 460A, 460B, engages with an opening 463 in the base body 30 of the second closure part 3 by acting on an edge section of this opening 310 causes the first closure part 2 against the engagement direction Y, which pushes the second closure part 2 with its engagement projections 220, 221 out of engagement with the engagement projections 320, 321 of the second closure part 3 upon actuation of the lever member 46, as shown in FIG Fig. 28D is shown.
  • The lever element thus serves, on the one hand, to lock the closure parts 2, 3 relative to each other in the closed position and, on the other hand, to support the opening process for separating the closure parts 2, 3 from one another.
  • The lever element 46 may be made, for example, as a metal part, for example as a sheet metal part made of a ferromagnetic material. This has the advantage that a magnet 25 acts on the first closure part 2 attracting to the lever element 46 and brings it into an initial position in which the closure parts 2, 3 can be attached to each other. In this initial position, the locking lugs 460A, 460B on the lever member 46 in a position in which they lock with the locking elements 33, 34 in abutment when the closure parts 2, 3 are attached to each other. Due to the magnetic effect on the lever element 46, the lever element 46 is also held in this position when the closure device 1 is in the closed position, so that the closure parts 2, 3 are locked in their position ( Fig. 28C ).
  • In addition, the lever member 46 may be biased for example via a mechanical spring element relative to the base body 20 of the first closure member 2 in the direction of its initial position, so that the lever member 46 is reset after actuation also due to the mechanical spring action in its initial position.
  • Such a mechanical preload makes sense, in particular, if no magnetic means are provided on the closure parts 2, 3 and the closure device 1 is thus designed purely mechanically or if (only) a magnetic armature is provided on the first closure part 2.
  • The provision of the lever member 46 can also be done by interaction of the lever portion 462 with the second closure member 3 by the lever portion 462 when attaching the closure parts 2, 3 comes into contact with the second closure member 3 while the lever member 46 is returned to its original position.
  • The possible applications for a closure device of the type described here are many. In particular, closure devices of the type described here can be used for connecting two parts, for example for connecting two straps, straps, ropes, cords or the like or as a closure for a bag, a lid, a box, a glove box, or other container. Closures of the type described herein can also be used for connecting other parts, for example for connecting objects to a backpack, a jacket or trousers, as a closure for satchels, for fastening objects to a sports helmet, for attaching mobile phones or computers to brackets, Attachment of accessories such as a bicycle lock on a bicycle or used to connect other parts.
