The closure device (2) has at least one opening retaining mechanism (4, 4A, 4B) by means of which the first and second closure parts (31, 32) are locked in the open position and which prevents a displacement of the first and second closure parts (31, 32) into the closed position by means of a retaining force.

Description

Technical Field

[0001] The proposed solution relates to a closure device for closing an opening formed between a first closure section and a second closure section. Background Art

[0002] The closing section can be part of a storage device. The cavity in the hollow body of the storage device can then be closed via an opening closed by means of a closing device. Such a storage device is, for example, provided for accommodating objects, such as electronic objects, such as cameras of mobile phones, tablet computers or laptops, etc., or also other objects of daily life, such as wallets or payment institutions, such as credit cards, documents, clothes and / or food. Such a storage device is used to accommodate objects and protect the objects, in particular from moisture or dust or also from other external influences. This should enable objects to be carried around in difficult environments, such as in water sports, but also, for example, at work. In principle, a storage device for accommodating liquids can also be configured and provided, wherein the liquid can then be introduced into the hollow body and / or removed from the hollow body via a closable opening.

[0003] The hollow body has, for example, a cavity formed between a first wall portion and a second wall portion, in which one or more objects or liquids to be accommodated in the storage device can be stored. In order to close the hollow body, a closing device is provided, which includes at least one first closing component and at least one second closing component. In one embodiment variant, the first closing component has a first strip extending in an elongated manner in a transverse direction and is arranged at a first closing section of the first wall portion, and the second closing component has a second strip extending in an elongated manner in a transverse direction and is arranged at a second closing section of the second wall portion. The first closing component and the second closing component act together by magnetic attraction, so that in the closed position in which the hollow body is closed, the first closing section and the second closing section are in contact with each other. Such a storage device is known, for example, from EP 2571 391 B1.

[0004] Although the storage device known from EP 2 571 391 B1 is simple for the user to operate, there is still a need in principle for a storage device or an improved closure device which is improved in this respect. Summary of the invention

[0005] A solution is provided in this regard by a closure device according to claim 1 .

[0006] Therefore, a closure device for closing an opening is proposed, wherein the closure device comprises at least one first closure component and at least one second closure component. The first closure component and the second closure component act together by magnetic attraction so that the opening is closed in the closed position of the closure device, for example, in such a way that the first closure component and the second closure component directly abut against each other, or the first closure section and the second closure section at which the first closure component and the second closure component are arranged directly abut against each other. In addition, the first closure component and the second closure component can be displaced into the open position against the magnetic force applied by the first closure component and the second closure component in order to release the opening. In addition, the proposed closure device has at least one open holding mechanism, via which the first closure component and the second closure component are locked in the open position, and the open holding mechanism prevents the first closure component and the second closure component from being displaced into the closed position by means of an (open) holding force.

[0007] The basic idea of ​​the proposed solution is therefore that the closure device can be held in an open position via at least one opening holding mechanism, without the user having to exert force on the closure device or its closure element for this purpose after the open position has been reached. The closure element is thus held in the open position without the user having to constantly act on the closure element. This makes it possible to facilitate the introduction of objects and / or liquids via the released opening and improves handling.

[0008] Thus, with locking of the open position via the open holding mechanism, the first closure part and the second closure part remain in the occupied open position and can only be transferred from the open position to the closed position again when the holding force is overcome. Thus, a holding force is applied by means of the locking, which holds the first closure part and the second closure part in the open position.

[0009] Furthermore, the magnetic attraction of the first closure part and the second closure part enables, after overcoming the holding force exerted by the open holding mechanism, the first closure part and the second closure part to be adjusted into the closed position in a magnetically supported manner at least for a part of the closing movement and the opening to be closed in this connection. Under the effect of the magnetic force, the closing sections rest against each other again, if necessary sealingly. This makes it easier for the user to close the opening and to keep the opening open with the proposed closure device, and improves the operability of the closure device of the closure system formed thereby.

[0010] In principle, it is also possible in the proposed closure device that the closure part is preloaded toward the closed position via at least one spring element and / or an elastic closure part. This supports the automatic closing of the closure device when the holding force of the opening holding mechanism is overcome. The corresponding preload can act in particular in a first region of the closing path spanned by the first closure part and the second closure part from the open position to the closed position, in which the magnetic force exerted by the first closure part and the second closure part is not sufficient (only) to cause the closure part to be adjusted into the closed position.

[0011] Thus, the automatic adjustment of the closure parts towards the closed position or the corresponding closing force can be provided by one or more spring elements, the magnetic attraction of the first and second closure parts and / or by the elastic design of the closure parts, so that the automatic adjustment of the first and second closure parts towards the closed position takes place after overcoming the holding force exerted by the at least one opening holding mechanism. Thus, for example, an operating force exceeding the holding force must only be applied manually at the closure device in order to unlock the opening holding mechanism and trigger the automatic adjustment of the closure parts towards the closed position.

[0012] Alternatively, in one embodiment variant, a restoring force can be applied by the open-holding mechanism toward the open position at least over a defined portion of the closing path toward the closed position, so that the closure device remains open or is transferred back into the open position even when an actuating force that exceeds the holding force is applied to the open-holding mechanism only briefly and / or in a magnitude that exceeds a threshold value by a large proportion. Therefore, a corresponding actuating force must then be applied, for example, by the user over a longer period of time and / or in a magnitude that exceeds a threshold value by a large proportion, in order to adjust the closure element, which has exceeded a defined dimension and thus a predetermined portion of the (total) closing path, toward the closed position, in order to prevent an automatic restoring of the closure element into the open position.

[0013] In principle, the closure part can be arranged to be arranged at the first closure section and the second closure section, so that the closure part can act on the closure section. Here, the opening can be formed between the first closure section and the second closure section. Therefore, in the open position, the closure sections are separated from each other. In the closed position, in order to close the opening, the first closure part and the second closure part can be in contact with each other, or the first closure part and the second closure part can be arranged there, in particular the first closure section and the second closure section integrated therein can be in contact with each other. Therefore, in the latter case, when the first closure part and the second closure part are in their closed position, the closure parts that act together magnetically can hold the closure sections magnetically in contact with each other in the closed position.

[0014] In order to provide magnetic interaction, the first closure part and / or the second closure part can be formed by magnetic materials respectively, for example, in a manner that the closure part is formed by plastic material, especially polymer material, or silicone material, which is mixed with magnetic material in the form of magnetic particles. Alternatively, the closure part can accommodate magnetic devices composed of discrete magnetic elements respectively, so that the closure parts act together by the interaction of the magnetic devices. It is conceivable that each closure part acts permanently, for example, in a manner that the closure part is constituted to have permanent magnetic particles and is made of permanent magnetic material, or in a manner that the magnetic devices of the closure parts are formed by the devices of permanent magnets respectively. However, it is also feasible that a closure part acts permanently in at least one section, and another closure part acts as a ferromagnetic armature in at least one section. For example, the closure part that acts ferromagnetically comprises a body composed of ferromagnetic material (for example, a plastic material mixed with ferromagnetic particles) or has a discrete ferromagnetic element. In principle, the proposed solution comprises in particular that at least one pair or a plurality of alternating magnetic elements and armatures are provided in one closure part and one or more offset pairs of armatures and magnetic elements are provided in the other closure part.

[0015] If the closure element has a magnetic device consisting of discrete magnetic elements, the discrete magnetic elements can be arranged linearly close to each other along a transverse axis, for example, wherein the discrete magnetic elements can be regularly spaced relative to each other along the transverse axis. However, it is also conceivable and feasible that the discrete magnetic elements are arranged in rows and columns according to a two-dimensional matrix, diagonally offset relative to each other and / or with different sizes and spacings relative to each other.

[0016] In principle, it is preferred that the holding force is preset in a way that can be overcome manually via the opening holding mechanism. Therefore, the proposed closure device configuration and is provided for manual operability, although this is certainly not mandatory. In an implementation variant, for example, it can be proposed that the holding force is not set in a way that can be overcome manually via the opening holding mechanism (first), and the opening holding mechanism includes a locking device, and before the opening holding mechanism allows the first closure part and the second closure part to be adjusted to the closed position again, the locking device must first preferably be manually unlocked. Therefore, as the opening position is reached, not only the opening position is locked, but also locking is also set at the same time, and the locking applies the holding force that resists adjustment. Therefore, in the case of not releasing the locking provided by the locking device, it is no longer possible to cause the first closure part and the second closure part to be adjusted to the closed position, and the locking device will not be irreversibly destroyed, damaged or worn. Therefore, although this improved opening holding mechanism for example requires an additional handle relative to a variant, the holding force applied by the opening holding mechanism in the variant can be overcome by only manually acting on the first closure part and the second closure part so that there is no additional separate displacement of the parts of the opening holding mechanism. However, this makes it possible to more reliably exclude an unintentional adjustment into the closed position.

[0017] The additional locking device can provide, for example, a positive locking of two locking parts which are arranged on two locking elements of the opening holding mechanism.

[0018] The holding force can be applied via at least one form fit, force fit and / or magnetic force. Thus, the first closure part and the second closure part can be locked in the open position via the open holding mechanism in a form fit, force fit and / or magnetic manner. In other words, the open holding mechanism can act in a form fit, force fit and / or magnetic manner to apply the holding force and thereby lock the first closure part and the second closure part in the open position.

[0019] An opening force can be applied via the opening holding mechanism, which at least supports the first closure part and the second closure part to occupy the open position and / or lock the first closure part and the second closure part in the open position. The opening force can be higher, especially maximum, in the open position of the first closure part and the second closure part than in the closed position, so as to support reaching and fixing the open position. In an embodiment variant, for the closed position, the opening holding mechanism is designed to make the opening force of the first closure part and the second closure part lower, especially minimum, than in the open position. In the closed position, the closing force applied by the first closure part and the second closure part, which supports the displacement of the first closure part and the second closure part toward the closed position, can be higher, especially maximum. The closing force is lower again in the open position, especially minimum.

[0020] In one embodiment, the open holding mechanism comprises at least one first locking element and at least one second locking element, wherein the first locking element and the second locking element act together in the open position to lock the first closure part and the second closure part in the open position. Here, the first locking element and the second locking element can act together magnetically, form-fittingly and / or frictionally to achieve locking of the closure part in the open position.

[0021] For example, the first locking element and the second locking element for locking the first closure part and the second closure part in the open position are adjusted from a rest position relative to each other into a locked position over a predetermined adjustment path. This includes in particular that the first locking element and the second locking element are adjusted together as the first closure part and the second closure part are displaced from the closed position into the open position, more precisely from the rest position into their locked position. However, this also includes that the adjustment of the locking element from the rest position into the locked position causes the closure part to be adjusted from the closed position into the open position. It also includes that at least one of the first locking element and the second locking element is arranged at one of the first closure part or the second closure part, in particular is formed there.

[0022] As already described above, the first locking element and the second locking element can act together, for example, magnetically attracting, so that the first closure part and the second closure part are locked in the open position. For example, in the context, the first locking element and the second locking element act together, magnetically attracting, so that the first locking element and the second locking element are automatically transferred to the locked position under the action of the magnetic force. The automatic transfer can depend on that the first locking element and the second locking element adjust the limited amount of at least a predetermined adjustment path relative to each other from their static position toward the locked position. In an embodiment variant, when the first locking element and the second locking element adjust at least half of the adjustment path relative to each other from their static position toward the locked position, especially adjust at least two-thirds of their adjustment path, for example, the locking element is (further) adjusted to the locked position by the magnetic force. Therefore, the first locking element and the second locking element are configured and dimensioned, especially in terms of the position and size of the magnetic element arranged at or in the locking element, so that when the closure device is opened outwardly beyond a limited amount, the locking element automatically adjusts to the locked position of the locked closure part.

[0023] In one embodiment variant, it can be alternatively or supplementally proposed that the magnetic force applied by the first locking element and the second locking element to support the displacement of the first locking element and the second locking element toward the locking position is higher, especially maximum, in the open position of the first closure part and the second closure part than in the closed position, and lower, especially minimum, in the closed position of the first closure part and the second closure part than in the open position, while the magnetic force applied by the first closure part and the second closure part to support the displacement of the first closure part and the second closure part toward the closed position is higher, especially maximum, in the closed position and lower, especially minimum, in the open position. Therefore, in this embodiment variant, the force variation curves of the corresponding (magnetic) closing force and the opening holding force are opposite, so that from the user's perspective, the opening and closing of the closure device are both comfortable and the closure parts are held in the open position and in the closed position with a sufficiently large force.

[0024] For example, the first locking element and the second locking element for locking the first closure part and the second closure part in the open position each have at least one magnetic element. The magnetic elements of the locking elements then act together to keep the locking element in the locked position. Additional magnetic elements may also be provided at at least one locking element in the first locking element and the second locking element. The additional magnetic element may be polarized oppositely to the magnetic element of the additional locking element, so that the magnetic elements of the first locking element and the second locking element repel each other in the static position, thereby (first) preventing the first locking element and the second locking element from shifting toward the locked position until the minimum adjustment path of the first locking element and the second locking element is crossed relative to each other. Therefore, one or more additional magnetic elements of the first locking element and the second locking element can support the static position when the closure device is closed by the locking element.

[0025] Alternatively or in addition, the first locking element and the second locking element can be coupled to the first closure part and the second closure part, in particular fixed or molded thereto, so that when the first closure part and the second closure part are displaced from the closed position into the open position, the first locking element and the second locking element are transferred into the locked position, in which the first locking element and the second locking element act together to lock the first closure part and the second closure part in the open position. For example, the first locking element and the second locking element can be pivoted into the locked position about the pivot axis or hinge axis respectively when the first closure part and the second closure part are displaced into the open position. The adjustment force for displacing the first closure part and the second closure part can be applied (manually) to the closure part and / or the locking element.

[0026] In one embodiment variant, the first locking element has at least one first magnetic element, and the second locking element has at least one second magnetic element. The first magnetic element and the second magnetic element can be displaced toward each other or at least partially over each other as the first locking element and the second locking element are displaced into the locking position. Therefore, the first locking element and the second locking element are implemented together with the first magnetic element and the second magnetic element arranged thereat and are arranged at the closure device so that as the first locking element and the second locking element are displaced from their resting position into the locking position, the displacement movement of the first magnetic element and the second magnetic element is displaced toward each other or at least partially over each other, so that the first magnetic element and the second magnetic element are close to each other and the locking element is kept in its locking position via an applied magnetic force or multiple applied magnetic forces.

[0027] In a first variant, the first magnetic element and the second magnetic element can be displaced towards each other as the first locking element and the second locking element are displaced into the locking position, so that, for example, the first magnetic element and the second magnetic element attract each other with a magnetic force, which acts substantially, in particular exactly parallel to the closing axis in the locking position, along which the first closure part and the second closure part can be displaced from the open position towards each other into the closed position after overcoming the holding force, and / or the magnetic force acts substantially, in particular exactly perpendicularly, to the hinge axis in the locking position, so that the magnetic force can displace the locking element from the rest position into the locking position. In the latter case, the force vector of the magnetic force can therefore lie in a normal plane with respect to the hinge axis and, for example, can also extend at an angle not equal to 90° relative to the closing axis.

[0028] In an alternative embodiment, in which the first magnetic element and the second magnetic element can be displaced at least partially over each other as the first locking element and the second locking element are displaced into the locking position, the first magnetic element and the second magnetic element attract each other with a magnetic force, which in the locking position acts substantially, in particular exactly perpendicularly, to the closing axis along which the first closure part and the second closure part can be displaced from the open position towards each other into the closed position after overcoming the holding force, and / or the magnetic force in the locking position acts substantially, in particular exactly parallel to the hinge axis, so that the locking element can be displaced from the rest position into the locking position. In the latter case, the force vector of the magnetic force can therefore lie in a plane in which the hinge axis also extends.

[0029] Alternatively or in addition to the magnetically supported locking of the first locking element and the second locking element, it can be proposed that the first locking element and the second locking element of the opening holding mechanism are connected to each other in a form-fitting manner in the open position of the first closure part and the second closure part, so as to lock the first closure part and the second closure part in the open position. This includes, for example, the following embodiment variant, wherein the first locking element and the second locking element are locked to each other in the open position of the first closure part and the second closure part, for example in such a way that at least one locking element arranged at a locking element in the locking element engages in a locking opening or another locking element, which is arranged at another locking element. In the locking elements that engage with each other, for example, the locking projections of the locking elements can be locked to each other. Therefore, when the first locking element and the second locking element have occupied their locking position, the elastic or elastically supported locking element, for example, the locking element in the form of a locking projection can be inserted into the locking opening or snapped into the locking opening or locked with another locking projection, so as to mechanically fix the occupied locking position. Here, the latching opening can be configured as a recess or groove on the locking element, for example. In particular, the mechanical locking should currently include a form-fitting connection for locking in the locking position by means of a ball latch or an elastically preloaded adjusting cam.

[0030] In one embodiment, the first closure part and the second closure part can be displaced from the open position towards each other into the closed position after overcoming the holding force applied by the open holding mechanism. The first locking element and the second locking element can be arranged to be arranged at the first closing section and the second closing section, so that at least one first locking element protrudes beyond the edge, preferably the lateral edge, of the first closing section, and at least one second locking element protrudes beyond the corresponding edge, especially the lateral edge, of the second closing section, so that the first locking element and the second locking element are opposite to each other. Therefore, the locking elements of the closure device protrude at the opposite edges of the first closing section and the second closing section, for example, in a transverse direction, along which the closure part extends in the closed position, or at an angle to the transverse direction, and the locking elements act together in the open position of the closure part to keep the closure part in the open position. This makes it easy to access and operate the open holding mechanism. On the other hand, when, for example, an opening force for transferring a closure part into an open position should be introduced at the locking element, the length of the (virtual) rod and thus the length of the lever force transmitted via the locking element can be changed relatively easily over the length of the projection of the locking element.

[0031] In a feasible improvement, the first closure part and the second closure part extend along the transverse axis, respectively, and the first locking element and the second locking element protrude beyond the end of the closure part along the transverse axis by at least one section. Similar to the design scheme of the locking element protruding beyond the lateral edge of the closing section explained above, the advantages of the locking element corresponding to the (lateral) protrusion beyond the end of the closing section can also be obtained.

[0032] In this context, it can also be proposed that the first locking element and the second locking element fix the first closure part and the second closure part in the locked position in the open position in order to lock the first closure part and the second closure part in the open position, and the first locking element and the second locking element each have (in particular constitute) an operating section coupled to the associated closure part for manual force action and are configured to adjust the closure part from its closed position to the open position by - due to an operating force manually applied at the operating section - shifting the first locking element and the second locking element from the rest position toward the locked position. Therefore, in the embodiment variant, an operating section is provided at the locking element, which is configured to apply an operating force in order to adjust the closure part from the closed position to the open position, in which the locking of the closure part is then carried out via the locking element. In this case, in addition to the operating sections of the first closure part and the second closure part, a corresponding operating section on the locking element side can also be provided, via which a manual force action on the closure part for shifting the closure part from the closed position to the open position and / or vice versa is realized or at least simplified. The operating section on the closure part side can be formed, for example, by a tongue-shaped protruding handle section. Alternatively, the operating section on the locking element side forms the only possibility for a prescribed force action arranged at the closure device to shift the first closure part and the second closure part from the closed position into the open position and / or vice versa.

[0033] In one embodiment variant, the first locking element and the second locking element are arranged to be arranged in a cavity that can be entered via an opening. The first end member of the first locking element and the second end member of the second locking element are spaced apart from each other in the closed position and act together in the open position to apply a retaining force. Therefore, in a storage device equipped with the proposed closure device, in the embodiment variant, when the first closure member and the second closure member are in their closed position, the locking element is located inside the cavity and is spaced apart from each other. For example, in the storage device, the first locking element and the second locking element inside are connected to the associated lateral edges of the closing section of the storage device or the section connected thereto, respectively, on the inside. With the opening of the closure device, the first end member and the second end member of the locking element inside the storage device approach so that the first end member and the second end member can act together to apply a retaining force. Therefore, with the transfer to the open position, for example, the first locking element and the second locking element are connected to each other at their first end member and the second end member and remain in the connected state. The connection of the end pieces then counteracts the adjustment of the first and second closure pieces into their closed position, since a force must first be applied (manually) to release the connection between the locking elements at the first and second end pieces.

[0034] For example, at least a first magnetic element and a second magnetic element may be provided at the first end member and the second end member, respectively. The first magnetic element and the second magnetic element of the first end member and the second end member may act together in a magnetically attractive manner in the open position of the first closure member and the second closure member, so as to fix the two end members to each other and thus exert a holding force that prevents the closure device from closing.

[0035] Alternatively or additionally, in the context of the invention, the first closure part and the second closure part extend respectively (in the closed position) along the transverse axis, and the first locking element and the second locking element are arranged to contact each other at their end parts by adjusting from the closed position into the open position, so as to act together, and in the open position, a tensioning force is applied to the end of the closure part arranged laterally along the transverse axis via the first locking element and the second locking element. If the end parts are connected to each other in the open position, the tensioning force that holds the first closure part and the second closure part in the open position is therefore maintained by the locking element with the end parts. Therefore, the tensioning force applied by the locking element in the open position of the first closure part and the second closure part when the end parts act together - if necessary, via the lateral edges of the storage device - acts respectively on the lateral outer ends of the two closure parts extending along the transverse axis. Thereby, for example, the closure part is supported and maintained to bend outwards transversely to the transverse axis via the tensioning force, via which the two closure parts release the opening in their open position.

[0036] In principle, a variant embodiment can propose that a plurality of (at least two) open holding mechanisms are part of the closure device. This then also includes, for example, that two pairs of locking elements are provided at the ends of the closure component spaced apart from each other along the transverse axis.

[0037] The first closing part and / or the second closing part can extend along the transverse axis, in particular extend in a strip shape. Therefore, the first closing part and / or the second closing part can in particular have a strip body extending longitudinally along the transverse axis.

[0038] In one embodiment variant, the first closure part and / or the second closure part is formed with at least two sections, which are connected to each other via a weakened area. The at least two sections can then be displaced relative to each other via the weakened area. Thus, at least two sections or segments are connected to each other via the weakened area in the material forming the corresponding closure part, for example in the manner of a film hinge, so that when the first closure part and the second closure part are adjusted between their closed position and their open position, the at least two sections are displaceable relative to each other - around the hinge axis defined by the weakened area. For example, the weakened area is formed by a cutout in the material of the corresponding closure part.

[0039] If a first closure part and / or a second closure part are provided, they can be separated from one another and separated in the transverse direction so that the flexible region at which the corresponding closure section of the first closure part or the second closure part is arranged can act as a film hinge.

[0040] Thus, flexibility can be introduced in a targeted manner during the production of the respective closure part via one or more weakened areas in the closure part, without the closure part itself having to be produced from a flexible or even elastic material (which is of course also possible in principle in the context of the proposed solution). Thus, the respective closure part can consist of an inherently rigid material in which sections are implemented that can be displaced relative to one another via one or more weakened areas. This includes, in particular, that the first closure part and / or the second closure part comprises a plurality of weakened areas, i.e. more than two, three or four weakened areas, so that the respective closure part forms a plurality of sections or segments that can be displaced relative to one another.

[0041] In another embodiment variant, the first closure part and the second closure part each extend along a transverse axis, and at least one of the opening retention mechanisms comprises a flexible, in particular elastic, locking element for being arranged in a cavity accessible via the opening, wherein the flexible locking element is arranged to apply a tensioning force to the ends of the closure parts arranged laterally along the transverse axis in the open position. In this context, the flexible tensioning element can act on its own at the opposite ends of the first closure part and the second closure part and / or preload at the lateral edges of the storage device, so that the first closure part and the second closure part can be transferred from their open position into the closed position only against the tensioning force applied by the flexible locking element. Therefore, in order to maintain the closed position of the first closure part and the second closure part, at least the tensioning force must always be overcome, via which the first closure part and the second closure part strive to adopt their open position.

[0042] For example, the flexible locking element is provided for being arranged in an intermediate wall section inside the cavity. Thus, in a storage device equipped with this embodiment variant of the proposed closure device, it can be provided that at least two compartments are defined in the storage device via the intermediate wall section in the cavity. The flexible locking element arranged in the intermediate wall section, typically in the region of the upper edge of the intermediate wall section facing the opening, then exerts a retaining force for maintaining the open position of the first closure part and the second closure part.

[0043] In this context, it can also be provided that the flexible locking element can be re-tensioned. Thus, the tensioning force applied by the flexible locking element can be manually readjusted. Thus, for example, a flexible locking element designed as a tensioning cord can be tensioned more strongly at a cord section accessible inside the cavity by manual pulling and locked in a correspondingly more strongly tensioned position via a clamp, in particular in the manner of a cord clamp provided on the garment.

[0044] In another alternative embodiment, a U-shaped tensioning element can be provided at the closure device for applying a holding force in the open position and thus maintaining the open position. Such a U-shaped tensioning element comprises a base and two legs connected to each other via the base, wherein the two legs are preloaded toward each other, and the tensioning element is provided for applying a holding force in the open position via the two legs preloaded toward each other. Thus, the tensioning element can be provided here to allow the first closure part and the second closure part to be adjusted from the open position to the closed position only by overcoming the preload force applied by the two legs. Under the action of the two legs, the first closure part and the second closure part thus strive to occupy and maintain their open position. In order to transfer the first closure part and the second closure part into the closed position, the preload force of the two legs is then manually overcome.

[0045] In one embodiment variant, the U-shaped tensioning element can be formed, for example, by a U-shaped spring element. The legs of the spring element, which are elastically prestressed toward each other and connected to each other via the base, then exert a holding force in the open position. In another embodiment variant, the tensioning element is not formed by a separate component, but, for example, by a U-shaped cavity, which is provided as part of the closure device in the edge of the storage device equipped with the closure device. In this case, the cavity is shaped such that, under the pressure exerted by the pumping cavity, the legs of the U are prestressed toward each other and are therefore pressed toward each other (inwards).

[0046] Another embodiment variant provides at least one spring strip for exerting a holding force, which is prestressed to prevent the first and second closure parts from being adjusted from the open position into the closed position. Such a spring element can, for example, support the (corresponding) curvature of the flexible first or second closure part by curvature transverse to the longitudinal extension direction of the spring strip, by means of which the respective closure part is displaced into the open position when no sufficiently high closing force acts on the first and second closure parts in order to (still) hold them in their closed position. For example, the spring strip can have a raised steel strip or be formed by a raised steel strip.

[0047] In a closure device configured with at least one spring strip, the spring strip can, for example, extend along the first closure part or the second closure part at the first closure part or the second closure part. Alternatively, at least one spring strip can be an integral component of the first closure part or the second closure part.

[0048] In another alternative embodiment, at least one spring strip extends between the end of the first closure part and the opposite end of the second closure part in the open position of the first and second closure parts. Therefore, in the last-mentioned embodiment, the spring strip prestressed toward the open position of the first and second closure parts seeks to space the opposite ends of the first and second closure parts relative to each other and keep them spaced apart. The transfer of the first and second closure parts from their open position to their closed position can again only be prevented by the reset force applied by the at least one spring strip. Until reaching their closed position, in which the first and second closure parts are prevented from resetting, the first and second closure parts thus always automatically assume their open position under the action of one or more spring strips.

[0049] In principle, the first closure part and the second closure part can form a closure composite in the closed position, which can be adjusted from a released state to a closed state, in which the first closure part and the second closure part can be moved away from each other for releasing the opening, in which the closure composite and at least one third closure part of the closure device act together so that the closure composite remains in the closed state. Thus, in the closed state, for example, the first closure section and the second closure section at which the first closure part and the second closure part are arranged are currently folded or rolled up, in particular in such a way that the first closure section and the second closure section and thus the wall of the storage device that may have the closure section are bent or folded at least once by 180°. Via the interaction of the closure composite and the third closure part, the closure composite is reliably maintained in the closed state thus occupied. Thus, an additional fixation of the closed state of the closure device can be provided, because before the first closure part and the second closure part can be displaced from the closed position into the open position, the closure composite must first be transferred from the closed state to the released state.

[0050] For example, the third closure part and the closure composite can interact mechanically, for example in a form-fitting manner, in particular via Velcro and / or magnetic attraction, in order to hold the closure composite in the closed state. In this case, the magnetic interaction also includes, for example, the interaction of at least one magnetic element of the third closure part with at least one magnetic element of the first closure part or the second closure part, via which the first closure part and the second closure part are held in the closed position. The at least one magnetic element of the first closure part or the second closure part thus has a dual function, interacting on the one hand with the magnetic element of the respective other (second or first) closure part and on the other hand with the third closure part.

[0051] The closed composite can be adjusted from the released state to the closed state, for example, around a pivot axis parallel to the first spatial direction, basically by folding or rolling up the first closing section and the second closing section at least once. The safety force, for example, the magnetic force, used to keep the closed composite in its closed state with respect to the third closing part then acts, for example, along a spatial axis, which is parallel to the second spatial direction extending perpendicularly relative to the first spatial direction. As already mentioned above, the closed composite together with the first closing part and the second closing part in the closed position can therefore be transformed from the released state to the closed state by pivoting the closed composite around a pivot axis parallel to the first spatial direction (for example, a Cartesian coordinate system with respect to the x direction). Therefore, for example, the closed composite can be flipped from the released state to the closed state. Therefore, the closed composite is flipped around a pivot axis parallel to the first spatial direction, for example, by about 180°. The (generated) magnetic force used to keep the closed composite in its closed state with respect to the third closing part then acts along a spatial axis, which is parallel to the second spatial direction (y) extending perpendicularly relative to the first spatial direction.

[0052] In principle, the third closure element can (also) extend longitudinally along the transverse axis, in particular be strip-shaped. In this case, for example, the third closure element is arranged in a section of the first wall of the storage device that is different from and offset from the first closing section. Thus, the third closure element can be arranged spatially offset from the first closure element, for example perpendicular to the transverse axis. In this embodiment variant, for example, at least one strip-shaped third closure element extends parallel to the strip-shaped first closure element, but is arranged transversely to the first closure element and offset therefrom.

[0053] In connection with a closure device having a third closure part for fixing the closure assembly in the closed state, it can be provided that the third closure part is provided for being arranged in a cavity accessible via the opening. If the closure assembly interacts magnetically with such an inner third closure part in order to fix the closed state, the corresponding magnetic element is therefore arranged in such a way that magnetic interaction through the wall of the storage device with the closure device is also possible.

[0054] With regard to the first closure part and the second closure part being kept in its open position after the closure composite is transferred to the release state, the third closure part inside can cause dual functions. Therefore, an embodiment variant can be proposed, and the third closure part that is arranged in the cavity is formed by two locking elements that open the holding mechanism. The two locking elements can be displaced relative to each other and overlap each other in the overlapping area when the first closure part and the second closure part are adjusted from the closed position to the open position. In the overlapping area, the sections of the two locking elements then act together and / or form-fit and / or force-fit each other in magnetic attraction, so as to apply a holding force. Therefore, in order to transfer the first closure part and the second closure part from the open position to the closed position, the connection of the first locking element and the second locking element that acts in the overlapping area must first be released again.

[0055] With regard to the magnetic attraction in the overlapping area, for the first-mentioned embodiment variant, it is also possible for the following magnetic elements of the two locking elements of the third closure part to interact with each other, which magnetic elements hold the closure composite in the closed state when the closure device is closed and thus when the closure composite is in the closed state by interacting with the magnetic elements of the first closure part.

[0056] In principle, the closure device can be provided for closing an opening through which the hollow body can be entered and / or the closure device can be provided for being arranged at the storage device. A possible hollow body can be delimited, for example, by at least one flexible wall, wherein the closing section is then arranged at or formed at such a flexible wall.

[0057] In one embodiment variant, the first closure part and / or the second closure part and / or the third closure part are elastically designed or are flexibly designed via one or more weakened regions with sections that can be displaced relative to one another. The closure parts can then have an increased rigidity, for example, relative to the wall of the hollow body on which the closure device is arranged, but are flexible in this case so that they can be bent, in particular about a vertical direction perpendicular to the transverse axis.

[0058] The proposed solution comprises in particular a storage device comprising a hollow body for accommodating at least one object and / or a liquid, wherein the at least one object and / or the liquid can be introduced into the hollow body via an opening which can be closed by an embodiment variant of the proposed closure device.

[0059] In one embodiment variant, the first closing element is enclosed, for example, between the inner layer and the outer layer of a first wall portion, which delimits the cavity of the hollow body to be closed by the closing device. Additionally or alternatively, the second closing element can be enclosed between the inner layer and the outer layer of the second wall portion of the hollow body. Thus, the corresponding closing element, which can be designed, for example, as a solid strip, is located in the intermediate space between the inner layer and the outer layer and is thus enclosed between the inner layer and the outer layer and is covered inwardly by the inner layer and outwardly by the outer layer.

[0060] In one embodiment variant, the first closing section is formed by the inner layer of the first wall and the second closing section is formed by the inner layer of the second wall. The closing sections of the respective wall are thus integrally formed at the inner layer of the respective wall. In the closed position, the closing sections bear against one another in a planar manner and establish a sealing portion which is, if necessary, sealed, so that the hollow body is closed to the outside (sealed), in particular fluid-tightly, so that no moisture can reach the interior of the hollow body. However, in the closed position, the opening can also be closed, in particular sealed, by bringing the first closing part and the second closing part directly into contact with one another. In principle, therefore, the closing parts can be arranged at the side of the wall on which the closing sections bear against one another in the closed state or at the side of the wall on the outside which does not bear against one another in the closed state.

[0061] In one embodiment variant, the first wall and / or the second wall are flexible. In particular, the first wall and the second wall can be flexible and soft, so that the hollow body can be deformed in a flexible, easily deformable manner so that its shape can be adjusted for accommodating objects. The hollow body is thus designed in the manner of a bag by the walls in such a way that objects, in particular electronic objects such as mobile phones or other everyday objects, can be accommodated and enclosed in a protective manner. Alternatively, the hollow body can be designed for accommodating liquids and thus, for example, as part of a drinking water bag.

[0062] In principle, the first wall and the second wall connected to the first closing section and the second closing section of the proposed closure device can be part of a continuous wall element. Thus, the first wall and the second wall can be formed in one piece in particular. For example, the first wall and the second wall, which are opposite in the cross-sectional view, can be formed by a single one-piece wall element in the form of a blow-molded part.

[0099] Figures 1 to 9A view of a first embodiment of a storage device 1 is shown, which has a hollow body 10, which is bounded by walls 101, 102 and is designed to accommodate objects, in particular electronic objects, such as mobile phones or other objects of everyday life, such as wallets or payment instruments. For example, the storage device 1 can be a bag or a bag. The storage device 1 can also be a liquid container, such as a drinking water bag. The liquid is then retained in the hollow body 10 and can flow out via an outlet provided at the hollow body 10, for example into a drinking water hose connected thereto.

[0100] The walls 101, 102 are connected to one another at parallel side edges that abut one another in the transverse direction x and a transverse axis extending parallel thereto and at the lower edge in the vertical direction z, for example by welding, gluing or folding at one of the edges mentioned, and are closed in the region of the upper end by the closure device 2 in such a way that the inner volume of the hollow body 10 or the cavity defined thereby is tightly closed in the closed position of the storage device 1. In principle, each wall 101, 102 can be formed by two layers, wherein the inner layer points to the inner volume of the hollow body 10 and the outer layer points to the outside. The walls 101, 102 are designed to be flexible so that the hollow body 10 can be deformed flexibly, in particular so that objects can be flexibly accommodated therein or expand when a liquid is accommodated in the hollow body 10.

[0101] The closure device 2 has three closure parts 31, 32, 33. Of the closure parts 31, 32, 33, the first closure part 31 is arranged at the closure section 101S of the first wall 101, and the second closure part 32 is arranged at the closure section 102S of the second wall 102, more precisely, the first closure part and the second closure part 31, 32 extend at the same height along the vertical direction z at the respectively associated wall 101, 102. The closure parts 31, 32 act together magnetically so that in the closed position of the closure device 2, the closure sections 101S, 102S formed by the inner layers of the respectively associated wall 101S, 102S are flat and thus sealingly abut against each other and form the closure composite 3.

[0102] The third closing member 33 is disposed at the front side 101A of the wall 101 at a section of the first wall 101 that is offset from the closing section 101S of the first wall 101 and is Figure 6 In the cross section of , as viewed from the closing section 101S along the extension path, it is arranged to be laterally offset from the first closing component 31 .

[0103] The closing elements 31 , 32 , 33 are each strip-shaped and extend along a transverse direction x and thus transversely to the vertical direction z.

[0104] The closure parts 31, 32, 33 are designed to act together magnetically. In the embodiment shown, the closure parts 31, 32, 33 are respectively made of plastic material or silicone material, and a row of permanent magnets are embedded in the plastic material or silicone material. In particular, the discrete magnetic elements 31M, 32M, 33M (of the magnetic device on the closure part side) can be accommodated in one or more closure parts of the strip-shaped closure parts 31, 32, 33. The discrete magnetic elements 31M, 32M, 33M are arranged close to each other along the transverse direction x, thereby forming a linear array of magnetic elements 31M, 32M or 33M. The closure parts 31, 32, 33 can have different poles here, so that the closure parts 31, 32, 33 act magnetically in pairs. In an alternative embodiment, non-same-name poles can also be alternated in the array of magnetic elements 31M, 32M or 33M of the closure parts. Such an array is then provided for cooperating with a corresponding counter-array at the other closure parts 32, 33, 31. The separate magnetic elements 31M, 32M, 33M of the magnetic device can each be formed by a separate permanent magnet, for example a permanent magnet made of a neodymium material. However, it is also conceivable that only one or two of the magnetic devices have separate permanent magnets, while the other one or more magnetic devices are formed by separate ferromagnetically active elements.

[0105] Alternatively, for example, only the first closure part 31 can act permanently magnetically, while the other closure parts 32, 33 are designed ferromagnetically, in particular as ferromagnetic armatures, so that the associated closure parts 32, 33 act as magnetic armatures. For example, it is also conceivable that the first and second closure parts 31, 32 are designed permanently magnetically, while the third closure part 33 acts ferromagnetically.

[0106] The closing sections 101S, 102S are pressed against each other in a planar manner by the first closing part 31 and the second closing part 32, so that the closing sections 101S, 102S formed by the inner layer of the wall parts 101, 102 are pressed against each other in the manner of a membrane and seal the hollow body 10. The closing composite 3 formed by the closing parts 31, 32 is held in a defined closed state by the third closing part 33, wherein the wall parts 101, 102 are folded by 180° in the area between the closing sections 101S, 102S and the sections that are offset transversely to the closing sections 101S, 102S, such as from Figure 1 This also improves the tightness of the closure device 2 in the closed state.

[0107] The first closure part 31 and the second closure part 32 each have a gripping element 310, 320 in the form of a web, on which a user can grip. By applying a force to the closure parts 31, 32, in particular to the gripping elements 310, 320, the closure parts 31, 32 can be released from the other third closure part 33 and adjusted to a released state. In the released state, the closure parts 31, 32 can move away from each other along the opening direction y (and thus at least partially along a closing axis 101S parallel thereto and oriented perpendicular to the transverse direction x and the vertical direction z), so that the closing sections 101S, 102S are separated from each other, so that the interior of the hollow body 10 can be entered through the opening O released thereby (see, for example Figure 7 and Fig. 8A ).

[0108] Figures 1 to 3 Different views of a storage device 1 with a closure device 2 in a closed state are shown, in which a closure assembly formed by first and second closure parts 31 and 32 is held in a closed state by means of a third closure part 33 at the front side 101A of the (first) wall 101. Figures 4 to 6 And with Figures 1 to 3 The same view shows the storage device 1 with the closure device 2 in the open release state. In the release state, the closure composite 3 is lifted off the third closure part 33, so that the first and second closure parts 31 and 32 can be displaced away from each other to release to the opening O of the hollow body 10. Figures 7 to 9 The storage device 1 is shown with the closure device 2 in the open position and its first and second closure parts 31 and 32. Figures 7 to 9 The views are relative to Figures 4 to 6 The view is rotated 180° so that, for example Figure 7 and Figure 8 The rear side 102B of the storage device 1 formed by the further second wall 102 is shown in each case.

[0109] In the open position, the two closure parts 31 and 32 are locked via two open holding mechanisms 4A and 4B, so that the closure device 2 remains open and the opening O remains accessible without the user having to constantly manually apply a force to the closure parts 31 and 32. Therefore, the open holding mechanism 4A or 4B applies an opening force, which at least supports the first and second closure parts 31, 32 to occupy the open position and / or locks the first and second closure parts 31, 32 in the open position. To this end, the open holding mechanism 4A or 4B is currently formed by means of two pairs of locking elements 41.1, 42.1 or 41.2, 42.2, respectively. Here, the locking elements 41.1, 42.1 or 41.2, 42.2 of the open holding mechanism correspond to the closed position of the first and second closure parts 31 and 32, respectively. Figures 4 to 6 In the rest position, the closure members 31 and 32 are spaced apart from each other. Figures 7 to 9 In the open position of the closure device 2, the locking elements 41.1, 42.1 or 41.2, 42.2 are adjusted from the rest position into the locking position, in which the open position of the closure parts 31 and 32 is locked in pairs via the locking elements 41.1 to 42.2. Thus, the two locking elements 41.1, 42.1 or 41.2, 42.2 of the opening and holding mechanism 4A, 4B of the closure device 2 can act together magnetically to lock the closure parts 31 and 32 in the occupied open position and exert a holding force, which must first be overcome by the user in order to displace the closure parts 31 and 32 toward each other again along the closing axis S and thus close the closure device 2.

[0110] The first locking elements 41.1 and 41.2 of the two opening mechanisms 4A and 4B are respectively associated with the first closure part 31 and fixed or formed thereon. Here, the first locking elements 41.1 and 41.2 protrude beyond the end of the corresponding strip-shaped closure part 31 along the X axis, which is called the transverse axis, along which the first closure part 31 extends. Thereby, each first locking element 41.1, 41.2 protrudes beyond the corresponding lateral edge 101R of the associated closing section 101S and thus the wall 101 to which it belongs. Similarly, the second locking elements 42.1, 42.2 of the opening and holding mechanisms 4A, 4B, which are arranged at the second closure part 32, also protrude laterally beyond the end of the second closure part 32 and the lateral edge 102R of the other closing section 102S of the storage device 1 and thus the lateral edge of the other wall 102.

[0111] In the first and second closing parts 31 and 32 corresponding to Figures 4 to 6In the closed position, the laterally protruding locking elements 41.1, 42.1 or 41.2, 42.2 of the opening holding mechanism 4A or 4B are bent with the protruding sections about the transverse axis or x-direction and are spaced apart from each other. Figures 7 to 9 1, 101S or 102S about a pivot axis or hinge axis parallel to the vertical direction z. With the pivoting movement accompanying the opening of the closure device 2, the locking elements 41.1, 42.1 or 41.2, 42.2 of the respective open holding mechanism 4A or 4B respectively cross the adjustment path s until the respective locking elements 41.1, 42.1 or 41.2, 42.2 abut against each other and thus assume their locked position.

[0112] The locking position is assumed with the support of magnetic force. To this end, each locking element 41.1 to 42.2 has a magnetic element 41M or 42M in a laterally protruding section. Here, the magnetic elements 41M, 42M of a pair of locking elements 41.1, 42.1 or 41.2, 42.2 of the opening and holding mechanism 4A or 4B act together by magnetic attraction to each other. Therefore, if the corresponding locking elements 41.1, 42.1 or 41.2, 42.2 of the opening and holding mechanism 4A or 4B approach each other to a defined extent by opening the closure device 2, the magnetic force exerted by the magnetic elements 41M, 42M is large enough so that the locking elements 41.1, 42.1 or 41.2, 42.2 are automatically adjusted towards each other to the position determined by the magnetic elements 41M, 42M. Figures 7 to 9 Visible locked position.

[0113] The magnetic attraction force exerted in the locked position then also defines the holding force exerted by the open holding mechanism 4A, 4B, which must be overcome on the user side in order to adjust the first and second closing parts 31 and 32 back toward the closed position and thus to close the opening O again. The holding force magnetically exerted by the magnets 41M, 42M of the open holding mechanism 4A or 4B acts essentially parallel to the closing axis S and thus along the Y axis or parallel to the Y direction.

[0114] exist Figures 1 to 9In the storage device shown in FIG. 1 , the longitudinally extending locking elements 41.1 to 42.2 are arranged on the respectively associated first or second closure part 31 or 32, but do not extend over the entire length of the respective closure part 31 or 32, so that the respective closure part 31 or 32 is additionally reinforced next to the respective lateral end of the respective closure part 31 or 32. In addition, the current closure parts 31 and 32 are each made of a material that is not flexible per se or is at least only flexible to a limited extent, in particular to support the flat contact of the closure sections 101S, 102S in the closed position of the first and second closure parts 31 and 32, in particular to support the sealing contact of the closure sections 101S and 102S. In order to ensure that the closure parts 31 and 32 and the third closure part 33 are bent when the storage device 1 is opened, a weakened area in the form of a cutout K is provided in a targeted manner on the closure parts 31, 32, 33. In the region of the respective cutout K, the material from which the respective closure element 31 , 32 or 33 is formed is reduced in a targeted manner so that sections of the respective closure element 31 , 32 or 33 are connected via the cutout K in an articulated and thus displaceable manner relative to one another in the manner of a film hinge.

[0115] In an embodiment variant, a plurality of separate (smaller or shorter) closing parts can also be provided separated from one another in the transverse direction. The closing parts are then completely separated from one another in the region of the cutout K. However, the flexible region of the respective closing section 101S or 102S or the wall 101 or 102 forming the respective closing section can then act as a film hinge.

[0116] exist Figures 10 to 18 In another embodiment variant of , alternatively designed opening and holding mechanisms 4A and 4B are provided. Whenever the same reference numerals are used here or in the drawings explained in detail below, the same components and functional elements are also represented in this regard.

[0117] therefore, Figures 10 to 18 The embodiment variant of the invention provides a pair of locking elements 41.1, 42.1 or 41.2, 42.2 for each open holding mechanism 4A and 4B, via which the closure parts 31 and 32 are locked in their open position. Here, the locking elements 41.1, 42.1 or 41.2, 42.2 also interact magnetically in pairs in order to lock the open position of the closure parts 31 and 32. Figures 1 to 9, in which the magnetic force of the magnetic elements 411M, 422M; 412M, 421M on the locking element side in the locked position acts along an action axis extending perpendicular to the closing axis S and thus parallel to the vertical direction z. Therefore, the corresponding magnetic elements 411M, 422M and 412M, 421M are then at least partially displaced over each other when the first and second closing parts 31, 32 are displaced from their closed position to the open position until the corresponding locked position is occupied. Therefore, each first magnetic element 412M or 422M of the locking element is then arranged at the end of the corresponding closing part 31 or 32 at the section of the corresponding locking element that at least partially surrounds the corresponding lateral edge 101R, 102R. The second magnetic element 411M or 421M is arranged at a distance at the other locking element, and the first magnetic element 422M or 412M in the locked position magnetically attracts and acts together with the second magnetic element for locking the open position. In this way, a sufficiently high magnetic attraction acts between the first magnetic element and the second magnetic element 412M, 421M and 422M, 411M by shifting the locking element 41.1, 41.2 or 41.2, 42.2 toward the locking position so that the locking element 41.1, 41.2 or 41.2, 42.2 is automatically further transferred to the locking position and held in the locking position.

[0118] Here, the first magnetic elements 412M, 422M of the locking elements 41.1, 42.1 or 41.2, 42.2 of the opening retaining mechanism 4A, 4B, which are arranged at partially surrounding and thereby protruding sections, can also be polarized oppositely to each other, so that the first magnetic elements 412M, 422M support the locking elements to remain in a stationary position in the closed position of the closure parts 31 and 32.

[0119] The first locking element or the second locking element 41.1, 41.2 (for the first closing part 31) or 42.1, 42.2 (for the second closing part 32) associated with the closing part 31 or 32 are now designed to be offset relative to each other. That is, the first locking element 42.1 is positioned below the second locking element 42.1 at the first opening and holding mechanism 4A - with respect to the vertical direction z - and can be pivoted, while the first locking element 41.2 is above the second locking element 42.2 arranged there at the other opening and holding mechanism 4B and can be pivoted.

[0120] Especially in Figures 10 to 18In a modification of the embodiment variant of the embodiment variant, the open holding mechanism 4A and / or the open holding mechanism 4B can additionally integrate a locking device, by means of which the locking position assumed by the corresponding pair of locking elements 41.1, 42.1 or 41.2, 42.2 is additionally fixed. For this purpose, for example, a movably supported latching pin (or another form-fitting element) is provided at one of the locking elements, which can at least partially sink into the latching opening or latching hole of the other locking element in a form-fitting manner when the locked position is reached. If the locking elements are to be displaced relative to each other again so that the closure parts 31, 32 are moved out of the open position, the latching pin must first be pressed or pulled out of the latching opening or latching hole. Instead of a locking pin combined with a locking opening or a locking hole, of course, another locking component (at least one of which is adjustably supported) can also be provided, by means of which, in particular, a shape-fitting and / or force-fitting locking of the two locking elements 41.1, 42.1 or 41.2, 42.2 of the opening retaining mechanism 4A, 4B can be achieved.

[0121] Figures 19 to 27 A variant embodiment proposes an open holding mechanism 4A, 4B of the closure device 2, in which the locking of the closure parts 31 and 32 in their open position is not performed magnetically, but purely mechanically. To this end, a first locking element 41.1 or 41.2 having a laterally protruding guide tab 413 is respectively engaged in a curved guide channel 423 of a second locking element 42.1 or 42.2 of the corresponding open holding mechanism 4A or 4B. When the locking element 41.1, 42.1 or 41.2, 42.2 is shifted from its rest position to the locked position, the guide tab 413 is guided in the corresponding guide channel 423. In this way, as the locked position is occupied, once the locked position is occupied, the locking element in the form of a locking protrusion 424 on the guide channel wall of the corresponding guide channel 423 can be snapped into the locking opening of the associated guide tab 413, which is configured as a locking groove 414, in a form-fitting manner. Therefore, in Figures 19 to 27 In the embodiment variant, the open positions of the first and second closing parts 31 and 32 are locked by mechanical locking of two locking elements 41.1, 42.1 or 41.2, 42.2 of the corresponding open holding mechanisms 4A and 4B.

[0122] If a sufficiently large actuating force is exerted in order to move the latching projections 424 out of their corresponding latching grooves 414 , the locking is released and the closure parts 31 and 32 can be moved along the closing axis S back into their closed position.

[0123] exist Figures 28 to 36In a variant embodiment, each locking element 41.1 to 42.2 is equipped with two magnets 411M, 412M or 421M, 422M in order to lock the open position of the closure parts 31 and 32 in a magnetically supported manner. Here, each locking element 41.1 to 42.2 has a respective support arm 425, which partially surrounds the lateral edge 101R, 102R at the longitudinal side of the storage device 1. A first magnetic element 412M or 421M is provided on the support arm 425. When the first and second closure parts 31, 32 are transferred into the open position and thus the closure device 2 is opened, the respective support arm 425 comes into contact with the base 426 of the respective other locking element by performing a pivoting movement. In the locked position, the magnetic force exerted by each magnet pair 412M, 422M or 411M, 421M of the opening holding mechanism 4A or 4B acts at an angle relative to the closing axis S and thus at an angle relative to the y direction, in the present case, for example, at an angle of approximately 45°. However, in the embodiments described (e.g. also in Figures 1 to 9 In the embodiment of the present invention, the magnetic force acts again in a normal plane relative to the hinge axis, about which the corresponding locking elements 41.1 to 42.2 can be pivoted from the rest position into the locking position.

[0124] exist Figures 28 to 36 In the embodiment variant, the locking elements 41.1, 42.1; 42.1, 42.2 are also implemented in a twisted manner relative to each other at the opening and holding means 4A and 4B of the closure part 31 or 32, so that, for example, the first locking element 41.1 of the first closure part 31 at the opening and holding means 4A is located with its support arm 425 below the support arm 425 of the second locking element 42.1 of the opening and holding means 4A with respect to the vertical direction z, while the second locking element 41.2 of the first closure part 31 at the other opening and holding means 4B is located with its support arm 425 above the support arm 425 of the second locking element 42.2 of the other opening and holding means 4B. Therefore, the magnetic element 411M or 421M on the base side is also positioned offset relative to the magnetic element 412M or 421M on the support arm side of the same locking element 41.1 to 42.2 with respect to the vertical direction z.

[0125] and Figures 28 to 36In contrast to the embodiment variant shown, it is of course also possible to provide, at the opening holding mechanism 4A or 4B, only one of the first or second closing parts 31, 32 with a locking element 41.1 to 42.2, which is L-shaped in cross section in the present case, and which can be pivoted about a hinge axis parallel to the spatial direction z when the closing part 31, 32 is displaced into its open position. The locking element cooperating with the pivotable locking element and by means of which the open position is then locked can then be formed, for example, only by a section of the end face of the closing part 32, 31, which is opposite to the closing part 31 or 32 having the pivotable locking element. The respective closing part 32 or 31 thus has a locking element integrated with a magnetic element 411M, with which the magnetic element 421M of the pivotable locking element (arranged in the support arm 425) cooperates in the locked position.

[0126] Figures 37 to 45 Another embodiment variant of the closure device 2 is shown, in which the magnetic elements 41M, 42M on the locking element side of the opening holding mechanism 4A or 4B are at least partially displaced one above the other when the first and second closing parts 31 and 32 are adjusted from the closed position to the open position. Here, the magnetic elements 41M and 42M of the opening holding mechanism 4A or 4B that act together are arranged in the head sections of the respective locking elements 41.1 to 42.2 that protrude laterally and are now disc-shaped. In the locked position, the magnetic force exerted by the magnetic element pairs 41M, 42M in order to lock the closing parts 31 and 32 in their open position then acts again perpendicularly to the closing axis S and thus parallel to the vertical direction z.

[0127] Figures 46 to 54 An implementation variant is Figures 1 to 9 Here, the opening and holding mechanisms 4A and 4B are constructed identically. Figures 1 to 9 Unlike the embodiment variant of , no gripping elements 310, 320 are provided on the first and second closure parts 31 and 32, via which the user can grip the first and second closure parts 31 and 32 in order to adjust the closure parts 31 and 32 between the closed position and the open position. More precisely, Figures 46 to 54 A variant embodiment provides that the locking elements 41.1 to 42.2, which are each formed integrally with the associated closure parts 31 and 32, are also provided for manually applying an operating force on the locking elements in order to move the closure parts 31 and 32 from Figures 49 to 512 is adjusted from the closed position illustrated in the figure to the open position. Therefore, the approach of the locking elements 41.1, 42.1 or 41.2, 42.2 of the opening and holding mechanism 4A or 4B to its locked position and the pivoting accompanying this automatically cause the first and second closing parts 31 and 32 to be pressed away from each other in their middle area. Therefore, the locking elements 41.1, 42.1 or 41.2, 42.2 of the opening and holding mechanism 4A or 4B respectively constitute an operating section for manual force action, so that by shifting the corresponding first and second locking elements 41.1, 42.1 or 41.2, 42.2 from their resting position to the locked position, the first and second closing parts 31 and 32 - when the closing composite 3 is in the released state - are adjusted from their closed position to the open position.

[0128] In order to support such operation of the closure device 2, the strip-shaped closure parts 31, 32 (and also the strip-shaped third closure part 33) can be made, for example, of an elastic material having discrete magnetic elements 31, 32 or 33 embedded therein or of an elastic magnetic material.

[0129] In accordance with Figures 55 to 60 In the improvement plan, Figure 46 to Figure 45 The embodiment variant of , however, only provides that the flexibility or elasticity required for the flexion of the first and second closure parts 31 and 32 when adjusted into the open position is not provided (only) by the material used for the first and second closure parts 31 and 32. Rather, a plurality of cutouts K extending parallel to the vertical direction z are provided on each first and second closure part 31 and 32. Thus, the first and second closure parts 31 and 32 are segmented here by the cutouts K. The individual magnetic elements 31 and 32 of the closure parts 31, 32 are then each arranged in one of the segments.

[0130] The longitudinally extending locking elements 41.1 to 42.2 are currently arranged at the end sides of the respective first and second closure parts 31, 32. Figures 1 to 9 Analogously to the exemplary embodiments of , the magnetic element 41M or 42M on the respective locking element side is arranged at a section of the respective locking element 41 . 1 to 42 . 2 which—in the closed position—is bent away from the respective closure part 31 or 32 with respect to the transverse axis or x-direction.

[0131] Fig.61 and Fig.62 According to Figures 46 to 54 The perspective view of the storage device 1 illustrates the use of the locking elements 41.1 to 42.2 for opening the opening and holding mechanism 4A, 4B of the closure device 2. Fig.61The storage device 1 is shown with the closure device 2 in the released state and the first and second closure parts 31 and 32 in the closed position. The user's hand H acts with two fingers F1 and F2, in this case the thumb and the index finger, on the locking elements 41.2 and 42.2 of the opening holding mechanism 4B. By pressing together, the locking elements 41.2, 42.2 correspond to Fig.62 The first and second closure parts 31 and 32 are brought close to each other while crossing the adjustment path s and thus the spacing between the two protruding sections of the locking elements 41.2 and 42.2, so that the locking elements are in contact with each other. Accompanying the pivoting movement of the locking elements 41.2, 42.2 caused thereby, the first and second closure parts 31 and 32 are pressed apart from each other at the edge of the opening O, so that the first and second closure parts 31 and 32 are transferred to the open position and the cavity 10 can be entered through the opening O. Due to the magnetic force exerted by the magnetic elements 41M and 42M of the opening holding mechanism 4A and 4B, the first and second closure parts 31 and 32 remain in the open position even if the user removes the hand H from the closure device 2.

[0132] Fig.63 Show Figures 19 to 27 A possible improvement of the embodiment variant of , in which an additional unlocking element in the form of an actuating ring 51, 52 is also provided at each of the open holding mechanisms 4A, 4B. Figures 19 to 27 In the embodiment variant, the latch connection with the latch projection 424 and the latch groove 414 can be designed in principle so that when a force is manually applied to the closure parts 31 and 32 in the open position, the latch is released without destruction and thus the locking is also released. Fig.63 It can also be provided that the corresponding form-fitting latches must be released individually by a previous additional force action on the corresponding open holding means 4A, 4B. Thus, for example, it may be necessary to pull on the actuating ring 51 or 52. The actuating ring 51, 52 is respectively connected to the section of the locking element 41.1 or 42.2 that forms the latching projection 424, so that the latching projection 424 can be disengaged from the corresponding latching groove by the action of force.

[0133] Instead of the illustrated actuating ring 51 or 52 , it is of course also possible to provide an alternatively designed unlocking element, for example a rigid ring.

[0134] As an alternative or in addition to the embodiment variants explained above, it can also be provided that the first and second closure part 31 and 32 are held in the open position via additional elements, for example via rods attached to the inner sides of the closure parts 31 , 32 .

[0135] Alternatively or in addition, the closure device 2 can also be configured with a delay device. This delay device is then configured to limit the locking in the open position in time after the closure parts 31 and 32 are transferred to the open position, before the closure parts 31 and 32 are automatically shifted back to the closed position again, for example, under the action of a corresponding preload, such as a spring elastic preload, toward the closed position. For example, the corresponding delay device can include one or more delay elements, such as delay elements in the form of a suction cup and / or an adhesive element. Therefore, the corresponding delay element of the delay device can apply a holding force that is reduced in time. The corresponding delay element can be arranged, for example, at a laterally protruding section of the locking element 41.1, 42.1 or 41.2, 42.2, and the delay element contacts each other in a locked manner as the locking element 41.1, 42.1 or 41.2, 42.2 is transferred to the locked position or the closure parts 31 and 32 are transferred to the open position. However, if the user does not apply further force to the corresponding open holding mechanism 4A or 4B, the holding force applied via the contact will be reduced continuously or suddenly after a predetermined duration. Once the corresponding reset force is greater than the reduced holding force, the first and second closure parts 31 and 32 are automatically adjusted to the closed position again.

[0136] FIG. 64A to FIG. 64B , FIG. 65A to FIG. 65D and Figures 66A to 66C A further variant of a bag-shaped storage device 1 is shown with an embodiment variant of the proposed closure device 2. Figures 64A to 66C The storage device 1 is designed as a bag or a bag, which can be worn by a person via a belt 7 on the back side 102B. On the front side 101A, an actuating tab 6 is provided on the closure device 2. By pulling on the actuating tab 6, the closure composite 3 of the closure device 2 can be pulled from the closed state - overcoming the magnetic force applied by means of the third closure part 33 - into the released state (see Figures 65A to 65C ) and in the released state then assumed, the strip-shaped first and second closure parts 31 and 32 are transferred into their open position (see Figures 65D to 65E ).

[0137] The end of the actuating tab 6 is fixed to the front side 101A in the region of the third closure part 33 so that the storage device 1 can be easily opened at the closure device 2 by manually pulling on the actuating tab 6 with relatively little manual force to overcome the corresponding magnetic force.

[0138] As per Figures 66A to 66CAs shown in the diagram, the closure device 2 which has been held open by means of the proposed opening holding mechanism can also be easily closed again by bringing the first and second closure parts 31 and 32 close to each other sufficiently strongly in their middle region so that they assume their closed position. Subsequently, the closure composite 3 is folded toward the third closure part 33 in the closed state.

[0139] In addition, Figures 64A to 65E The feasibility of simply opening the storage device 1 with one hand by means of the operating tab 6 (or another handle-shaped or tab-shaped operating element) in the embodiment variant is also advantageous in principle, the first closure part and the second closure part 31 and 32 are not held in the open position via the opening holding mechanism. Therefore, the storage device 1 can be opened by the user via the operating tab 6 with the help of a smooth movement - back and forth in different movement phases. By pulling on the operating tab 6, the closure composite 3 can first be flipped from the magnetically held closed state to the released state. Subsequently, in the released state, the first and second closure parts 31 and 32 that are magnetically held to each other can be separated from each other via the operating tab 6 and transferred from the closed position to the open position. In this context, maintaining the open position via the opening holding mechanism can be additionally advantageous, but is only optional.

[0140] In addition, Figures 64A to 65E Unlike the storage device 1 shown in FIG. 1 , the user is not obliged to act on the back side 102B when the storage device 1 is secured via the waist belt 7. Furthermore, another type of fastening may also be provided instead of the waist belt 7.

[0141] Figures 67A to 69C A further embodiment variant of a bag-shaped storage device 1 is shown in different views with an embodiment variant of the proposed closure device 2 which, when the closure device 2 is opened, holds the closure device 2 in the open state via an opening retention mechanism.

[0142] exist Figures 67A to 69C In the storage device 1 of FIG. 1 , the actuating tab 6 is re-arranged at the front side 101A of the storage device 1. Here, the ends of the actuating tab 6 are respectively fastened at the intermediate space between the centrally arranged third closure part 3 and the respectively adjacent other third closure part 331 or 332. The three third closure parts 331, 33 and 332 are respectively designed in strip shape and are arranged one after another along the transverse axis.

[0143] In particular, according to Fig.67C A partial three-dimensional top view and Fig.68A and Fig.68B As shown in the enlarged view, Figures 67A to 69CThe storage device 1 of the present invention has an open holding mechanism 4, which has an internal flexible locking element in the form of an (elastic) tensioning cord 40. An intermediate wall 40A is provided inside the storage device 1, via which the internal cavity of the storage device 2 is divided into two - in the present case approximately equal - compartments I1 and I2. The tensioning cord 4 is guided inside the intermediate wall 40A at the upper edge facing the opening O that can be closed by the closing device 2, thus in the region of the upper edge of the intermediate wall 40A. Inside the storage device 1, two mutually opposite (longitudinal) edges of the storage device 1 are connected to each other via the tensioning cord 40 and pretensioned toward each other. The corresponding tensioning force applied by the tensioning cord 40 then also acts on the first closure part 31 and the second closure part 32 connected to each other at the end sides at the lateral longitudinal edges, so that the first closure part 31 and the second closure part 32 are pretensioned into their open position via the tensioned tensioning cord 40. Thus, under the action of the tensioned tensioning cord 40 , the middle regions of the strip-shaped first and second closure parts 31 and 32 are pressed outward when the magnetic force by which the first and second closure parts 31 , 32 are held against each other in the closed position is manually overcome.

[0144] In order to re-tension the tensioning cord 40 if necessary and thus to be able to readjust the tensioning force applied thereto, a cord section in the form of a cord loop is guided out of the intermediate wall 40A. When the storage device 1 is opened, the cord section corresponds to the user. Fig.68B The user can then pull with one hand on the rope section in order to strongly tension the tensioning rope 40. By pulling the rope section that is pulled further out of the intermediate wall 40A, it can be locked here via the rope locking device 400, for example in the manner of a rope clamp, in order to maintain the adjusted rope tension. Closing of the storage device 1 corresponds to Figures 69A to 69C The approach of the first and second closure elements 31 and 32 to one another takes place counter to the tensioning force exerted by the tensioning cable 40 .

[0145] In the corresponding Fig.70A and Fig.70B In the embodiment variant of the storage device 1, the volume of the storage device 1 is designed differently. Thus, for example, a smaller bag or a smaller package is possible. As part of the opening holding mechanism 4, an internal tensioning cord 40 is also provided here, which runs in the intermediate wall section 40A and can be re-tensioned via a cord locking device 400.

[0146] exist Figures 71A to 71CIn a variant embodiment of the storage device 1, the third closure element 33 is not arranged at the front side 101A, but is arranged inside the storage device 1, via which the closure composite 3 can be magnetically held in the closed state. In addition, the third closure element 33 is designed separately here, so that it is composed of two longitudinally extending sections, which can act as locking elements 330 and 331 of the open holding mechanism 4 for the open position.

[0147] The two longitudinally extending locking elements 330 and 331 of the third closure part 33 directly adjoin each other in the closed position of the first and second closure parts 31, 32 (both in the closed state and in the released state). The closure composite 3 can thus be held in the closed state via the magnetic elements arranged in the locking elements 330, 331 of the third closure part 33 and their magnetic interaction with the magnetic elements of the first closure part 31, as has been explained above.

[0148] However, in Figures 71A to 71C When the closure device 2 of the storage device 1 is opened, the two strip-shaped locking elements 330 and 331 connected to the left edge of the storage device are now displaced relative to each other, so that the locking elements correspond to Fig.71B Overlap with each other. In the resulting overlapping area UB in which the sections of the locking elements 330 and 331 are arranged opposite to each other in an overlapping manner, the magnetic elements of the first and second locking elements 330 and 332 act in an attractive manner to each other, so that the overlapping position of the locking elements 330 and 331 is maintained. Therefore, the locking elements 330 and 331 of the third closure part 33, which are magnetically attracted to each other in the overlapping position, hold the longitudinal edges of the storage device 1 in a position close to each other, thereby holding the first and second closure parts 31, 32 in the currently occupied open position.

[0149] If the closure device 2 is opened further, in that the first and second closure parts 31 and 32 are more strongly arched outward, the two locking elements 330 and 331 of the first closure part 33 are displaced relative to each other. The overlapping area UB increases. By the magnetic elements that attract each other in the overlapping sections of the locking elements 330, 331, the magnetic elements are then also maintained in a further opened position. Closing is only possible when the magnetic force is overcome in order to separate the locking elements 330, 331 from each other.

[0150] Fig.72A and Fig.72BThe holding-open mechanism 4 of the storage device 1 is based on a similar principle. Here, an opening holding mechanism 4 is provided in the interior of the storage device 1, and the opening holding mechanism has two locking elements 41.1 and 42.1 spaced relative to each other in the closed position of the first closure part 31 and the second closure part 32. Magnetic elements 411M or 421M are respectively provided at the end parts facing each other of the two locking elements 41.1 and 42.1 in the interior. If the two end parts of the two locking elements 41.1 and 42.1 carrying the corresponding magnetic elements 411M and 421M approach each other when the closure device 2 is opened, the connection between the two locking elements 41.1 and 42.1 is established by the magnetic attraction of the two magnetic elements 411M and 421M. As a result, the locking elements 41.1 and 42.1 connected to each other exert a holding force at the longitudinal edges of the storage device 1, thereby exerting it on the first and second closure parts 31, 32 in its open position. The transfer of the first and second closure part 31 , 32 into their closed position is only possible by overcoming the holding force, so that the two magnetically fixed locking elements 41 . 1 and 42 . 1 are separated from each other again.

[0151] exist Fig.73A and Fig.73B In a variant embodiment of the storage device of , an open holding mechanism 4 is provided which has a U-shaped tensioning element, in this case in the form of a spring element 8. The U-shaped spring element 8 extends with a base 8.3 along the lower edge of the storage device 1. Two legs 8.1 and 8.2 lying opposite one another are connected to one another via the base 8.3 and extend along the edge of the longitudinal side of the storage device 1, in this case in the surrounding edge section R of the storage device 1. The two legs 8.1 and 8.2 are prestressed toward one another (see also Fig.73B ). Here, the legs 8.1, 8.2 end in the region of the upper edge of the storage device 1 that forms the edge of the opening O, so that the preload force of the two legs 8.1, 8.2 is also transmitted to the two closure parts 31 and 32, which are again strip-shaped. Under the effect of the preload of the legs 8.1 and 8.2, the first and second closure parts 31 and 32 try to bend outwards in their open position. Therefore, it is only possible to overcome the preload force applied by the legs 8.1, 8.2 and the corresponding holding force in order to approach the first and second closure parts 31 and 32 to their closed position. Therefore, after the closure device 2 is opened, the open position is maintained under the effect of the two legs 8.1 and 8.2.

[0152] The same applies to the corresponding Fig.74A and Fig.74BImplementation variant. Here, an open holding mechanism 4 having two spring (steel) strips 43.1 and 43.2 is provided. The spring strips 43.1 and 43.2 extend along the corresponding associated closure parts 31 or 32 or are integrated components of the corresponding closure parts 31 or 32. The first spring strip 43.1 is associated with the first closure part 31, and the second spring strip 43.2 is associated with the second closure part 32. Each spring strip 43.1 or 43.2 is prestressed in the direction of the camber, more precisely, in the following manner, so that under the action of the spring strips 43.1 and 43.2, the strip-shaped closure parts 31 and 32 are prestressed outwardly in their middle areas to form an camber. Therefore, in order to close the closure device 2 so that the first closure part 31 and the second closure part 32 occupy their closed position, the user must overcome the spring force of the two spring strips 43.1 and 43.2 and press the middle areas of the first closure part 31 and the second closure part 32 onto each other.

[0153] exist FIG. 75A to FIG. 75B A similar principle is proposed in the storage device of FIG. Here, two spring bands 43.1 and 43.2 are provided as part of two open holding mechanisms 4A, 4B. The first spring band 43.1 is arranged between the first and second closing parts 31 and 32. Fig.75A Another spring strip 43.2 in turn extends between the other right longitudinal ends of the first and second closure parts 31 and 32.

[0154] The first and second spring strips 43.1 and 43.2 are each intended to be oriented straight and thus prestressed into a state in which the corresponding spring strip 43.1 or 43.2 is stretched in a straight line. In the closed position of the first and second closure parts 31, 32, the two spring strips 43.1 and 43.2 are each bent once (centered) and in the once bent state are held by the magnetic force of the first and second closure parts 31 and 32 that are magnetically attracted to each other. If the magnetic force is manually overcome, the spring strips 43.1 and 43.2 automatically flip over due to their respective prestressing forces, whereby the first closure part 31 and the second closure part 32 are shifted into their open position and the first closure part 31 and the second closure part 32 are held in the open position spaced apart from each other (see Fig.75B ).

[0155] For example, in Fig.76A and Fig.78B The storage device can be used to Fig.75A and Fig.75B The storage device 1 is configured as a backpack that can be carried on the back via two carrying straps T1 and T2.

[0156] In the closed state, Figures 76A to 78B The two opposite walls of the backpack 1 are folded or rolled up. The corresponding Figures 76A to 76C To this end, the fixing member 90 cooperates with the counterpart 91 of the closure member 9 at the front side 101A of the backpack 1. If the locking, which may be magnetically supported, between the fixing member 90 and the counterpart 91 is released, the bag 1 can be closed. Figures 77A to 77C The backpack 1 is unfolded at its upper side so that the closure device 2 together with the closure assembly 3 is transferred to the released state. In the released state, the two first and second closure parts 31 and 32 held magnetically in the closed position can be transferred manually to the open position.

[0157] In the open position, the closure parts 31 and 32 are held by an open holding mechanism having spring strips 43.1, 43.2. Only after overcoming the holding force applied by the spring strips 43.1 and 43.2, the two first closure parts 31 and the second closure parts 32 are thus moved closer to each other again and transferred to their closed positions.

[0158] The concept on which the proposed solution is based is not restricted to the exemplary embodiments described above, but can also be realized in completely different ways.
