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 here. Then, the cavity in the hollow body of the storage device can be closed via an opening blocked by means of a locking device. Such a storage device is, for example, configured to accommodate objects, such as electronic objects, such as cameras of mobile phones, tablet computers or laptops, or other objects of daily life, such as wallets or payment tools, 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 other external influences. This should enable objects to be carried around in difficult environments, such as in water sports, but also at work or in daily life. In principle, the storage device can also be configured and arranged to accommodate liquids, wherein the liquid can then be introduced into the hollow body and / or taken out from the hollow body via a closable opening.

[0003] The hollow body has a cavity, for example, 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 locking device is provided, which includes at least one first locking component and at least one second locking component. In one embodiment variant, the first locking component has a first strip extending longitudinally in a transverse direction and is arranged at a first closing section of the first wall portion, and the second locking component has a second strip extending longitudinally in a transverse direction and is arranged at a second closing section of the second wall portion. The first and second locking components 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 2 571 391 B1.

[0004] With regard to the operability of the closure device, there is a need for an improved opening mechanism, especially for such storage devices, for example the closure device is designed for child safety and accordingly a child cannot easily gain access to the interior of the storage device. Summary of the invention

[0005] In said aspect, the locking device of claim 1 provides a solution.

[0006] Therefore, a locking device for closing an opening is proposed, the locking device having at least one first locking part and at least one second locking part. The first and second locking parts extend between two longitudinal ends along a longitudinal axis respectively and have sections opposite to each other between the longitudinal ends. The (locking) sections of the first and second locking parts can be shifted into an open position in order to release the opening. In addition, the first and second locking parts act together, for example, magnetically act together or are implemented so that in the closed position of the locking device, the opening is closed and the closing force must be overcome so that the sections of the first and second locking parts are adjusted from the closed position to the open position. In order to shift the (first and second) sections of the first and second locking parts into the open position, the locking device has at least one manually operable opening mechanism, the opening mechanism comprising a first operating element coupled to the first locking part and a second operating element coupled to the second locking part. The first and second operating elements are respectively configured with operating sections, which are arranged at the longitudinal ends of the first locking part or the second locking part to which they belong. Furthermore, in the closed position of the first and second locking parts, the first and second operating elements are in a safety position, from which they can be adjusted into an operating position, wherein by adjusting the first and second operating elements into the operating position, sections of the first and second locking parts can be shifted into the open position.

[0007] In the closed position, the opening can be closed, for example, by sections of the first and second closure elements being brought directly into contact with one another or by a first closure section and a second closure section on which the first and second closure elements are arranged being brought into contact with one another.

[0008] Therefore, the basic idea of ​​the proposed solution is that the opening mechanism is provided with a first and a second operating element coupled to the locking part, via which the locking device can be opened, wherein the operating sections of the first and second operating elements arranged on the longitudinal side are grasped (directly or indirectly) by the user. Here, the possibility of opening the locking device in a targeted manner is provided via the first and second operating sections of at least one opening mechanism, for which the opening force to be applied can be set relatively simply, so that the (adjusting) force to be applied to the first and second operating elements exceeds the minimum force that cannot be easily applied by a child. The direct or indirect force action of the user is here particularly understood to mean that the user manually introduces the adjusting force into the corresponding operating section at the operating section without the intermediate connection of another component for force transmission. Correspondingly, the indirect or indirect force action of the user includes that the force manually applied by the user is introduced into the force transmission element coupled to the operating section and is transmitted to the operating section. For example, in this context, the force transmission element can be a flexible pulling mechanism, such as a rope end, a ring or a belt.

[0009] With the proposed closure device, it is also possible to provide a storage device for accommodating objects which are not only to be arranged in a manner protected from moisture or dirt or other external influences, but are also to be secured against accidental access, in particular by children. Thus, a storage device equipped with the proposed closure device can be provided in particular for accommodating medicines, hobbies, tools, (household) chemicals, cosmetics, objects for self-defense and / or pyrotechnic objects (e.g. flares, weapons, ammunition or fireworks) and not only for accommodating documents, clothing and / or food.

[0010] In principle, the first and second operating elements can be arranged on the corresponding locking part, in particular connected to the locking part, including being fixed to the locking part, in particular being bonded or molded on the locking part, so that the force introduced at the operating section of the operating element can be transmitted to the corresponding (locking) section of the locking part.

[0011] The operating section of the first operating element and / or the operating section of the second operating element can protrude at the longitudinal end of the corresponding first locking part or second locking part, in particular protrude beyond the corresponding longitudinal end of the corresponding first locking part or second locking part. This includes in particular that the operating section protrudes at the corresponding longitudinal end along the longitudinal axis or at an angle to the longitudinal axis.

[0012] The locking device may also include two opening mechanisms, wherein the first opening mechanism has a first pair of first and second operating elements at the first longitudinal ends of the first and second locking parts, and the second opening mechanism has a second pair of first and second operating elements at the second longitudinal ends of the first and second locking parts. The locking device can be configured in principle in this case so that in order to open the locking device in accordance with the regulations, the user must grip both first and second opening mechanisms and must act on the corresponding first and second operating elements. However, it is also conceivable that the user must also selectively grip only the operating element of one opening mechanism in order to cause the locking device to open.

[0013] In the first variant described above, an opening force that overcomes the closing force can only be applied, for example, when both the first and second operating elements of the first opening mechanism and the first and second operating elements of the second opening mechanism are adjusted to the corresponding operating position, in order to shift the sections of the first and second closure parts into the open position. Thus, the closing force applied by the first and second closure parts and the operating elements or the opening force that can be applied thereby are coordinated with each other, so that only when the first and second operating elements are adjusted can a sufficient opening force be applied at both opening mechanisms. Thus, the size of the achievable lever force is preset, for example, by the length of the operating section protruding on the longitudinal side, so that when the operating element is adjusted to its corresponding operating position, the resulting opening force exceeds the closing force. Since it is necessary to operate the two opening mechanisms in order to achieve the adjustment of the sections of the first and second closure parts into the open position and thus to open the closure device, this embodiment variant provides an additional safety device to prevent accidental or undesired opening.

[0014] Alternatively, when adjusting the first and second operating elements, an opening force exceeding the closing force can be applied to one of the opening mechanisms in order to displace the sections of the first and second closure parts into the open position. This also applies to variants in which the closure device has exactly one opening mechanism.

[0015] When adjusting the first and second operating elements from their safety position into their actuation position, they can be adjusted towards each other or at least partially overlap each other, for example. Thus, the operating section of the operating element can be provided, for example, for the application of force on the user's side by means of a thumb and a finger (for example the index finger or the middle finger) of a hand. By pressing together accordingly, the operating elements can then be adjusted towards each other or at least partially overlap each other, for example, in order to cause the locking device to be opened.

[0016] In one embodiment variant of the proposed locking device, after the closing force has been overcome in order to adjust the sections of the first and second locking parts from the closed position toward the open position, a reset force also prevents adjustment or retention into the open position. Under the action of the reset force, the sections of the first and second locking parts automatically shift back into the closed position as soon as a sufficiently high adjustment force is no longer applied. As a result, in this embodiment variant, not only is the locking device only able to be opened after the closing force has been overcome, but further opening is also made difficult, so that even after the closing force has been overcome, a specific (minimum) opening force exceeding a threshold value must be applied in order to open the locking device further and to keep it open. The reset force required for this is brought about towards the closed position, for example magnetically (for example by magnets that repel each other and prevent complete opening of the locking device) and / or by an inherent elastic and / or magnetic or mechanical prestressing of the components of the locking device.

[0017] The first and second operating elements can apply an opening force in their operating position, which inhibits the locking component from being displaced into the closed position. Here, for example, the opening force applied by the first and second operating elements in the operating position acts substantially perpendicularly to the longitudinal axis.

[0018] In one embodiment variant, the first and second operating elements are held to each other in their operating position by a form fit, a friction fit or by means of a magnetic force. For example, the first and second operating elements attract each other by a magnetic force in their operating position. Thus, the magnetic attraction force of the operating element - for example via a magnetic element arranged in the operating section - can cause or at least support the locking of the occupied operating position and the associated open position of the sections of the first and second closure parts. In this way, the closure device can, for example, remain open without having to continue to act on the operating element on the user side.

[0019] For this purpose, the magnetic force by means of which the first and second operating elements are attracted in their actuated position can, for example, act substantially perpendicularly to the longitudinal axis along which the sections of the first and second closure parts (in their closed position) extend. The magnetic force can then also act, for example, parallel to or perpendicularly to the closing axis along which the closing section can be displaced from the closed position into the open position.

[0020] The locking of the assumed operating position can also be achieved by form fit and / or friction fit. In this case, at least one of the operating elements can be designed to be elastically deformable so that in the operating position it is elastically deformed in interaction with the other operating element and a friction fit is generated between the two operating elements or it is locked in an undercut in the manner of a snap-fit ​​between the operating elements or in a hybrid form with a snap-fit ​​form fit, both in an undercut and in a friction fit clamping manner.

[0021] The operating element can be pivoted from its safety position into its actuation position in principle.Thus, the first and second operating elements can be pivoted at the locking device, for example, respectively, about a pivot axis or hinge axis extending perpendicularly to the longitudinal axis.

[0022] In one embodiment variant, at least one opening mechanism can be part of a childproof device of the closure device in order to close the opening securely for children. Thus, a childproof device can be implemented relatively easily with the proposed closure device, since the exercisable opening force can be relatively easily preset via the laterally protruding operating sections of the first and second operating elements. In particular, the opening force can be preset to prevent the closure device from being opened by a child's hand.

[0023] For example, in one embodiment variant, it is proposed that the first and second operating elements can only be adjusted from their safety position to their operating position when an adjustment force exceeding a threshold value is applied. Here, the threshold value can be at least 25N, 30N, 35N, 40 or 50N. Alternatively or in addition, the threshold value can exceed the value of the maximum gripping force that can be applied by 90 percent of children under 52 months. Thus, only by means of an adjustment force exceeding a correspondingly set threshold value can an opening force exceeding the closing force be applied to the sections of the first and second closure parts via the operating element in order to adjust the sections into the open position.

[0024] Furthermore, the magnetic attraction of the first and second closure parts enables, at least for a portion of the closing movement, the first and second closure parts to be adjusted into the closed position in a magnetically supported manner and, in conjunction with this, to close the opening. Under the effect of the magnetic force, the closing sections come to rest against one another again, possibly tightly against one another. This makes closing the opening easier for the user and improves the operability of the closure device of the closure system formed thereby.

[0025] In principle, it is also possible in the proposed locking device that the locking part is preloaded toward the closed position via at least one spring element and / or an elastic locking part. This supports the automatic closing of the locking device. It is possible to cause the preload toward the closed position either by spring preload / elastic preload on the one hand or by magnetic force on the other hand. However, it can also be advantageous to combine the forces. The corresponding preload can act in particular in the first region of the closing stroke to be bridged by the first and second locking parts from the open position to the closed position, in which the magnetic force exerted by the first and second locking parts is not sufficient (only) to cause the adjustment of the locking part into the closed position.

[0026] 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 holding the sections of the first and second closure parts in the open position. Thus, for example, only an actuating force that exceeds the holding force is manually applied to the closure device in order to trigger the automatic adjustment of the closure parts towards the closed position.

[0027] In principle, the locking element is designed to be arranged at the closing section so that the locking element can act on the closing section. Thus, when the first and second locking elements are in their closed position, the locking elements that act together magnetically can hold the closing sections magnetically against each other in the closed position.

[0028] In order to provide magnetic interaction, the first locking part and / or the second locking part can be formed of a magnetic material, for example, in such a way that the locking part is formed of a plastic material, in particular a polymer material, or a silicone material, which is mixed with a magnetic material in the form of magnetic particles. Alternatively, the locking parts can each accommodate a magnetic device consisting of discrete magnetic elements, so that the locking parts act together magnetically by the interaction of the magnetic devices. It is conceivable that each locking part acts permanently magnetically, for example, in such a way that the locking part is formed with permanent magnetic particles and is thus made of a permanent magnetic material, or in such a way that the magnetic devices of the locking parts are respectively formed by a device of a permanent magnet. However, it is also possible that one locking part acts permanently magnetically at least in one section, and the other locking part acts as a ferromagnetic armature in at least one recess. For example, the ferromagnetic locking part comprises a body, which is composed of a 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.

[0029] If the locking element has a magnetic device consisting of discrete magnetic elements, the discrete magnetic elements can be arranged linearly close to each other along the longitudinal axis, for example, wherein the discrete magnetic elements can be regularly spaced relative to each other along the longitudinal 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 and / or are arranged with different sizes and spacings relative to each other.

[0030] In one embodiment, the first closure part and / or the second closure part is formed with at least two (sub) sections, which are connected to each other via a membrane or weakened area located inside and connected to the corresponding closure part. Then, at least two sections can be displaced relative to each other via the weakened area. Therefore, at least two sections or segments are connected to each other via the weakened area in the material constituting the corresponding closure part, for example in the manner of a film hinge, so that when the first and second closure parts 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 cut in the material of the corresponding closure part. If the closure part is formed with at least two sub-sections, which are connected via a membrane located inside and connected to the corresponding closure part, this includes the following variant, in which the first closure part and / or the second closure part has a plurality of sections separated from each other. The sections can be separated along the longitudinal axis, so that the flexible region of the membrane provided with the first closure part or the second closure part can be used as a film hinge.

[0031] Thus, via one or more weakened areas in the locking part, flexibility is introduced in a targeted manner during the manufacture of the corresponding locking part, without the locking part itself having to be manufactured from a flexible or even elastic material (which is of course also possible in principle during the proposed solution). Thus, the corresponding locking part can consist of an inherently rigid material in which sections that can be displaced relative to each other are realized by one or more weakened areas. This includes, in particular, that the first locking part and / or the second locking part comprises a plurality of weakened areas, i.e. more than 2, 3 or 4 weakened areas, so that the corresponding locking part forms a plurality of sections or segments that can be displaced relative to each other. The same applies to separate locking parts that are connected only by means of a membrane located in the interior and connected to the locking section. By reducing the spring elasticity of the locking part by means of the above-mentioned weakened area or separated section, the reset force is reduced and the force required for locking in the operating position is thereby reduced. Thus, when locking in the operating position by means of a magnet, for example, the required magnet size can be reduced.

[0032] In principle, the first and second locking parts can form a locking compound in the closed position, which can be adjusted from a released state into a locked state, in which the first and second closing sections can be separated from each other for releasing the opening, in which the locking compound and the third locking part of the locking device cooperate to keep the locking compound in the locked state. Thus, in the locked state, the first and second locking sections can be present, for example, in a folded or rolled-up state, in particular in such a way that the first and second closing sections and thus the wall of the storage device that may have the closing sections are folded or bent at least once by 180°. Through the interaction of the locking compound and the third locking part, the locking compound is reliably kept in the locked state thus occupied. Thus, an additional safety guarantee for the closed state of the locking device can be provided, because before the first and second locking parts can be displaced from the closed position into the open position, the locking compound must first be transferred from the locked state to the released state.

[0033] In order to provide child safety at the closure device, it may be advantageous for the closure assembly to remain in the closed state. Therefore, when the closure assembly is in the closed state, the closure assembly must first be adjusted into the released state before the closure section can be adjusted into the open position by actuating at least one opening mechanism. Therefore, when the storage device is closed properly via the closure device, a specific operating sequence for opening is required, which cannot be easily carried out by children, in particular by young children.

[0034] For example, the third closure part and the closure assembly can interact in a form-fitting manner, in particular via a snap-fit ​​and / or magnetic attraction, in order to hold the closure assembly in the closed state. In this case, magnetic interaction also includes, for example, interaction of at least one magnetic element of the third closure part with at least one magnetic element of the first or second closure part, via which interaction the first and second closure parts are held in the closed position. The at least one magnetic element of the first or second closure part thus performs 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.

[0035] The locking assembly can be adjusted from a released state into a locked state, for example, about a pivot axis parallel to the first spatial direction, essentially by folding or rolling up the first and second closing sections at least once. A safety force, for example a magnetic force for holding the locking assembly in its locked state relative to the third locking part, then acts, for example, along a spatial axis parallel to a second spatial direction extending perpendicularly to the first spatial direction. As already mentioned above, the locking assembly together with the first and second locking parts present in the closed position can therefore be transferred from a released state into a locked state by pivoting the locking assembly about a pivot axis parallel to the first spatial direction, for example a Cartesian coordinate system relative to the x-direction. Thus, for example, the locking assembly can be folded from a released state into a locked state. Thus, the locking assembly is hereby flipped about a pivot axis parallel to the first spatial direction, for example by approximately 180°. The (generated) magnetic force for holding the closure assembly in its closed state relative to the third closure part then acts along a spatial axis which is parallel to a second spatial direction (y) which runs perpendicularly to the first spatial direction.

[0036] In principle, the third locking part can (also) extend longitudinally along the longitudinal axis, in particular be designed in the form of a strip. In this case, for example, the third locking part is arranged in a section of the first wall of the storage device that is different from the first closing section and is offset. The third locking part can therefore be arranged spatially offset relative to the first closing section, for example perpendicular to the longitudinal axis. In this embodiment variant, the third locking part, for example in the form of a strip, extends parallel to the first locking part in the form of a strip, but is arranged transversely offset relative to the first locking part.

[0037] In principle, the closure device can be provided for closing an opening through which the hollow body can be accessed and / or the closure device can be designed for being arranged on a storage device. A possible hollow body can be bordered, for example, by at least one flexible wall, wherein the closing section is then arranged on or formed on such a flexible wall.

[0038] In one embodiment variant, the first closure part and / or the second closure part are elastically designed at their closure sections and / or the third closure part, or are flexibly designed via one or more weakened regions with (sub)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 provided with the closure device, but are flexible in this case, so that they can be bent, in particular about a vertical direction perpendicular to the longitudinal axis.

[0039] 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 implementation variant of the proposed closure device.

[0040] In one embodiment variant, the first closure part is enclosed, for example, between the inner layer and the outer layer of a first wall part, which surrounds the cavity of the hollow body to be closed by the closure device. Additionally or alternatively, the second closure part can be enclosed between the inner layer and the outer layer of the second wall part of the hollow body. Thus, the corresponding closure part, 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. However, in the closed position, the opening can also be closed, in particular sealed, by the first and second closure parts being directly in contact with each other. Thus, in principle, the closure part can be arranged on the side of the wall part on which the closing sections are in contact with each other in the closed state or on the side of the wall part that is not in contact with each other on the outside in the closed state.

[0041] 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 section of the respective wall is thus integrally formed on the inner layer of the respective wall. In the closed position, the closing sections bear against one another in a planar manner and form a possibly sealed end, so that the hollow body is sealed to the outside (tightly), in particular fluid-tightly, so that no moisture can reach the interior of the hollow body.

[0042] 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 and can be adjusted in its shape for receiving an object. The hollow body is thus designed in the form of a bag by the wall, in such a way that an object, in particular an electronic object such as a mobile phone or another everyday object, can be received and surrounded in a protective manner. Alternatively, the hollow body can be designed for receiving a liquid and thus, for example, as part of a drinking water bag.

[0043] In principle, the first and second walls connected to the first and second closing sections of the proposed closure device can be parts of a continuous wall element. Thus, the first and second walls can be formed in one piece in particular. For example, the first and second walls, which are opposite in cross-sectional view, can be formed by a single one-piece wall element in the form of a blow-molded part.

[0062] Figures 1 to 9 A view of a first embodiment of a storage device 1 is shown, which has a hollow body 10, which is bordered 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 pocket 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, which can flow out via a device arranged at the hollow body 10, for example into a drinking hose connected thereto.

[0063] The walls 101, 102 are connected to one another at parallel side edges spaced apart from 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, and are closed in the region of the upper end by a closure device 2 in such a way that the interior 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 interior 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 flexibly deformed, in particular so that objects can be flexibly accommodated therein or expansion can occur in the hollow body 10 when accommodating a liquid.

[0064] The closure device 2 has three closure components 31, 32, 33. Of the closure components 31, 32, 33, the first closure component 31 is arranged on the closing section 101S of the first wall 101, and the second closure component 32 is arranged on the closing section 102S of the second wall 102, more precisely, the first and second closure components 31, 32 extend at the same height along the vertical direction z on the respectively associated walls 101, 102. The closure components 31, 32 act together magnetically so that the closing sections 101S, 102S, respectively formed by the inner layers of the associated walls 101S, 102S, are flatly and thus tightly abutted against each other in the closed position of the closure device 2 and form the closure assembly 3.

[0065] The third locking member 33 is arranged 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 , starting from the closing section 101S and viewed along the extension path, it is arranged to be laterally offset from the first locking component 31 .

[0066] The locking elements 31 , 32 , 33 are each designed with a strip-shaped locking section 310 , 320 , 330 , which extends along the transverse direction x and thus transversely to the vertical direction z.

[0067] The locking parts 31, 32, 33 are designed to act together magnetically. In the embodiment shown, the locking parts 31, 32, 33 are respectively made of plastic material or silicone material, and a row of permanent magnets is embedded in the plastic material or silicone material. In particular, the discrete magnetic elements 31M, 32M, 33M (of the magnetic device on the locking part side) can be accommodated in one or more of the bar-shaped locking parts 31, 32, 33. The discrete magnetic elements 31M, 32M, 33M are arranged with each other along the transverse direction x, thereby forming a linear array of magnetic elements 31M, 32M or 33M. The locking parts 31, 32, 33 can have poles with different names, so that the locking parts 31, 32, 33 act on each other in pairs by magnetic attraction. The discrete magnetic elements 31M, 32M, 33M of the magnetic device can be formed by discrete permanent magnets, for example, permanent magnets composed of neodymium material. However, it is also conceivable that only one or two of the magnetic devices have discrete permanent magnets, while the other magnetic device(s) are formed by discrete ferromagnetically acting elements.

[0068] Alternatively, for example, only the first locking part 31 can act permanently magnetically, while the other locking parts 32, 33 are designed ferromagnetically, so that the associated locking parts 32, 33 act as magnetic armatures. For example, it is also conceivable that the first and second locking parts 31, 32 are designed permanently magnetically, while the third locking part 33 acts ferromagnetically.

[0069] 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 in contact with 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 section that is offset transversely relative to the closing sections 101S, 102S, such as from Figure 1 This further improves the tightness of the closure device 2 in the closed state. In principle, it is also conceivable that, in order to close the opening, the closure sections 310 , 320 arranged on the inner side at the closing sections 101S, 102S abut against each other.

[0070] By applying an opening force to the locking parts 31, 32, the locking parts 31, 32 can be disengaged from the other third locking part 33 and adjusted to a released state. In the released state, the locking parts 31, 32 can move away from each other along the opening direction y and the closing axis S oriented parallel thereto and 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 ).

[0071] Figures 1 to 3 Different views of a storage device 1 with a locking device 2 in a locked state are shown, in which the locking assembly formed by means of the first and second locking parts 31 and 32 is held on the front side 101A of the (first) wall 101 by means of the third locking part 33 in the locked state. 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 opened release state. In the release state, the closure assembly 3 is opened from the third closure part 33 so that the first and second closure parts 31 and 32 can be moved 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.

[0072] exist Figures 1 to 9 In a variant embodiment, the operating elements 41.1 to 42.2, which are respectively formed - if necessary in one piece - with the associated locking parts 31 and 32, are provided for manually applying an adjusting force in order to move the locking parts 31 and 32 from Figures 4 to 6The closed position illustrated in the figure is adjusted into the open position. Thus, the approach of the operating element 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A or 4B to its actuation position and the accompanying pivoting automatically cause the mutually opposite central locking sections 310, 320 of the first and second closure parts 31 and 32 to be pressed apart from each other. The operating element 41.1, 42.1 or 41.2, 42.2 is provided here for manual force action, so that by manually adjusting the corresponding first and second operating elements 41.1, 42.1 or 41.2, 42.2 from their safety position to the actuation position, the first and second locking sections 310 and 320 - when the closure assembly 3 is in the released state - are adjusted from their closed position into the open position.

[0073] In order to support such an operation of the locking device 2, the strip-shaped locking parts 31, 32 (like the strip-shaped third locking part 33) can be made of an elastic material with a discrete magnetic element 31, 32 or 33 embedded therein, or made of an elastic magnetic material. Alternatively, at least the first and second locking parts 31 and 32 can each consist only of a material that is not flexible per se or at least only limitedly flexible, in particular to support the planar contact of the closing sections 101S, 102S in the closed position of the first and second locking parts 31 and 32, in particular to support the close contact of the closing sections 101S and 102S.

[0074] In order to transfer the locking sections 310, 320 of the two locking parts 31 and 32, two opening mechanisms 4A and 4B are provided on the locking device 2. The opening mechanism 4A or 4B is formed with two pairs of operating elements 41.1, 42.1 or 41.2, 42.2 respectively. The operating elements 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A or 4B correspond to the first and second locking parts 31 and 32 in the closed position. Figures 4 to 6 In the safety position, the locking sections 310, 320 of the locking parts 31 and 32 are spaced apart from each other. Figures 7 to 9 in the open position.

[0075] By providing that the locking device 2 is opened (only) via the paired operating elements 41.1, 42.1 and 41.2, 42.2 of the two opening mechanisms 4A, 4B, the locking device 2 can be easily protected from accidental opening by children. Therefore, the adjustment force required for opening to be applied at the operating elements 41.1, 42.1 or 41.2, 42.2 or at the operating sections protruding respectively on the longitudinal sides of the operating elements can be set so that the adjustment force is above a threshold value that cannot be easily applied by a child's hand. Due to the existing lever ratio, the locking segments 310 and 320 are displaced against the magnetic force that holds the locking segments 310, 320 in the closed position, so that an adjustment force exceeding a defined threshold value is required, which adjustment force typically cannot be applied by a child under a certain age with his or her hands alone. For example, it is provided in this context that the adjustment force to be applied must be higher than 25 N, 30 N, 35 N, 40 N or 50 N and / or the threshold value exceeds the value of the gripping force which can be applied maximally by 90% of children under 52 months.

[0076] Therefore, the opening mechanism 4A, 4B integrates the child safety device into the locking device 2 in order to prevent children from opening the storage device 1 or at least make it difficult for children to open the storage device 1. In this regard, it is also advantageous to keep the locking compound 3 (optionally) in the locked state. Therefore, when the locking compound 3 is in the locked state, before the closing sections 310 and 320 can be adjusted to the open position completely by operating the opening mechanism 4A or 4B or the two opening mechanisms 4A and 4B, the locking compound 3 must first be adjusted to the released state. Therefore, when the storage device 1 is closed via the locking device 2 in accordance with the regulations, a specific operating sequence for opening is required, which cannot be easily implemented by children, especially by young children. But at the same time, the locking device remains easy and intuitive to operate for users of higher age (greater than 52 months).

[0077] In the open position, the two operating elements 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A, 4B of the locking device 2 can act together magnetically to lock the locking sections 310 and 320 in the occupied open position and apply a holding force, which must first be overcome by the user in order to shift the locking parts 31 and 32 toward each other again along the closing axis S and thus close the locking device 2.

[0078] The first operating elements 41.1 and 41.2 of the two opening mechanisms 4A and 4B are respectively associated with the first locking part 31 and fixed or formed thereon. Here, the first operating elements 41.1 and 41.2 respectively protrude beyond the longitudinal ends of the first bar-shaped locking part 31 along the X-axis, which is called the longitudinal axis, along which the first locking section 310 extends. Thereby, each first operating 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 operating elements 42.1, 42.2 of the opening mechanisms 4A, 4B arranged at the second locking part 32 also protrude laterally beyond the end of the second locking part 32 and the lateral edge 102R of the other closing section 102S and thus the other wall 102 of the storage device 1.

[0079] The first and second locking members 31 and 32 correspond to Figures 4 to 6 In the closed position of the opening mechanism 4A or 4B, the laterally protruding operating elements 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A or 4B are bent with the protruding sections about the longitudinal axis or x-direction and are spaced apart from each other. Figures 7 to 9 1, 42.1 and 41.2, 42.2 are pivoted in pairs toward one another, more precisely at the respective closing section 101S or 102S about a pivot axis or hinge axis parallel to the vertical direction z. By means of the pivoting movement, the operating element 41.1, 42.1 or 41.2, 42.2 of the respective open holding mechanism 4A or 4B respectively bridges the adjustment path s until the respective operating element 41.1, 42.1 or 41.2, 42.2 abuts against one another and thus assumes its operating position.

[0080] Currently, the occupation of the operating position is prevented in a magnetically supported manner or by repelling magnets. To this end, each operating element 41.1 to 42.2 has a magnetic element 41M or 42M in a laterally protruding operating section. Here, the magnetic elements 41M, 42M of a pair of operating elements 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A or 4B act together magnetically by attraction or repulsion. Therefore, if the corresponding operating elements 41.1.42.1 or 41.2, 42.2 of the opening mechanism 4A or 4B approach each other to a defined extent, the magnetic force exerted by the magnetic elements 41M, 42M is large enough to automatically adjust the operating elements 41.1, 42.1 or 41.2, 42.2 toward each other to a certain extent. Figures 7 to 9 The visible operating position may make the adjustment difficult, so that the user needs to apply a higher adjustment force or place higher requirements on the motor drive capacity.

[0081] The magnetic attraction force exerted in the actuated position (in the case of magnet attraction polarization) is then also defined as the holding force exerted by the opening mechanism 4A, 4B, which must be overcome on the user side in order to adjust the first and second closure parts 31 and 32 back to the closed position and thus to close the opening O again. The holding force magnetically exerted by the magnets 41M, 42M of the opening mechanism 4A or 4B acts here essentially parallel to the closing axis S and thus along the Y axis or parallel to the Y direction.

[0082] exist Figures 10 to 15 In another embodiment variant of , alternatively designed opening 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.

[0083] In order to ensure that the locking parts 31 and 32 are also bent like the third locking part 33 when the storage device 1 is opened, the locking sections 310, 320, 330 of the locking parts 31, 32, 33 are made of flexible and, if necessary, elastic materials. The locking sections 310, 320, 330 present in the open position are prestressed toward the closed position in the described manner. In order to increase the flexibility of the locking sections 310, 320, 330 or to achieve this only when using less flexible materials, a weakened area in the form of a cutout K can be provided in a targeted manner in a further development. In the area of ​​the corresponding cutout K, the material forming the corresponding locking part 31, 32 or 33 is reduced in a targeted manner, so that the (sub) sections of the corresponding locking parts 31, 32 or 33 are connected in an articulated manner via the cutout K in the manner of a film hinge so as to be displaceable relative to each other.

[0084] Therefore, according to Figures 10 to 15 The improvement plan is Figures 1 to 9 The embodiment variant of provides differently that the flexibility or elasticity required for the flexion of the first and second closure sections 310 and 320 when adjusted into the open position is not (only) provided 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 in each of the first and second closure parts 31 and 32 in the region of the closure sections 310, 320. 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.

[0085] The longitudinally extending operating 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 9Analogously to the exemplary embodiments of the present invention, the magnetic element 41M or 42M on the respective operating element side is arranged at a section of the respective operating element 41 . 1 to 42 . 2 which is bent away from the respective locking part 31 or 32 with respect to the longitudinal axis or x-direction in the closed position.

[0086] In one embodiment variant, the locking section 310 and / or the locking section 320 can be separated from one another at the location of the shown cutout K. The locking sections 310 , 320 are then completely separated from one another in the region of the cutout K. However, in this case, the flexible region of the respective closing section 101S or 102S or the wall 101 or 102 forming the respective closing section can act as a film hinge.

[0087] Fig.16 and Fig.17 According to Figures 1 to 9 The three-dimensional view of the storage device 1 illustrates the use of the operating elements 41.1 to 42.2 for opening the opening mechanism 4A, 4B of the locking device 2. Fig.16 The 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 operating elements 41.2 and 42.2 of the opening mechanism 4B. By pressing together, the operating elements 41.2, 42.2 correspond to Fig.17 When the adjustment stroke s is bridged and thus the spacing between the two protruding operating sections of the operating elements 41.2 and 42.2 is bridged, the operating elements 41.2 and 42.2 are brought closer to each other so that the operating elements abut against each other. With the resulting pivoting movement of the operating elements 41.2, 42.2, the first and second closure sections 310, 320 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.

[0088] Due to the magnetic force applied by the magnetic elements 41M and 42M of the opening 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. Alternatively, it can be provided that the magnetic elements 41M and 42M of a pair of operating elements 41.1, 42.1 or 41.2, 42.2 repel each other. To this end, after the hand H is removed, the closure sections 310, 320 can be additionally supported to move to the closed position and prevent the closure device 2 from being unintentionally held open.

[0089] Fig.18 and Fig.18AThe embodiment variant of also shows two end-side opening mechanisms 4A and 4B, each of which has a pair of operating elements 41.1, 42.1 or 41.2, 42.2, via which the locking parts 31 and 32 can be adjusted into their open position and can be locked. Fig.18A and Fig. 14B An enlarged sectional view of one of the opening mechanisms 4A, 4B is shown in the same manner. Here, the operating 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 The embodiment variant is different, in which the four magnetic elements 411M, 422M; 421M (wherein Figure 8 B) acts along an action axis extending perpendicularly to the closing axis S and thus parallel to the vertical direction z. Therefore, the corresponding magnetic elements 411M, 421M, 422M are at least partially displaced overlapping each other when adjusted to shift the first and second locking parts 31, 32 from their closed position into the open position until the corresponding operating position is occupied. Therefore, each first magnetic element 422M of the operating element is arranged at the end of the corresponding locking part 31 or 32 at a section of the corresponding operating element that at least partially surrounds the corresponding lateral edge 101R, 102R. For this purpose, the second magnetic element 411M or 421M is arranged at a distance at each other operating element, and the first magnetic element 422M of an operating element (only the operating element 42.1 is shown in the figure) acts together with the second magnetic element in the operating position by magnetic attraction for locking the open position. In this way, a sufficiently high magnetic attraction force acts between the first magnetic element and the second magnetic element, for example the magnetic elements 422M, 411M, when the operating elements 41.1, 41.2 or 41.2, 42.2 are displaced toward the operating position, so that the operating elements 41.1, 41.2 or 41.2, 42.2 are automatically further transferred to the operating position and remain in the operating position.

[0090] The first magnetic elements 422M of the operating elements 41.1, 42.1 or 41.2, 42.2 of the opening mechanism 4A, 4B, which are arranged on partially enclosed and thus protruding sections, can also be polarized opposite to each other, so that the first magnetic elements 422M support the operating elements to remain in a safe position in the closed position of the locking parts 31 and 32.

[0091] The first operating element or the second operating 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 locking part 31 or 32 are designed to be offset relative to each other. That is, the first operating element 42.1 is located below the second operating element 42.1 on the first opening mechanism 4A - with respect to the vertical direction z - and can be pivoted, while the first operating element 41.2 is located above the second operating element 42.2 arranged there on the other opening mechanism 4B and can be pivoted.

[0092] In addition, Fig.18 and Fig.18A In a variant embodiment, a strap-shaped gripping section 311 or 321 is also provided on each of the first and second locking parts 31, 32. Here, the corresponding gripping section 311, 321 is provided on the corresponding locking section 311 or 321, for example, molded thereon, and is formed on the locking device 2. Fig.18 In the released state shown in FIG. 3 , the gripping sections 311 and 321 are provided for manual force application by the user to facilitate folding the closure composite 3 from the closed state to the released state. In addition, this can also facilitate the adjustment of the closure sections 310 and 320 from the open position to the closed position.

[0093] exist Figures 19 to 19A In a variant embodiment, each operating element 41.1 to 42.2 is respectively equipped with two magnets 411M, 421M in order to lock the open position of the locking parts 31 and 32 in a magnetically supported manner. Here, each operating element 41.1 to 42.2 has a supporting arm 425, which partially surrounds the lateral edges 101R, 102R at the longitudinal side of the storage device 1. A first magnetic element 421M is respectively provided on the supporting arm 425. In order to shift the first and second locking sections 310, 320 into the open position and thus open the locking device 2, the corresponding supporting arm 425 is in contact with the base 426 of the corresponding other operating element by performing a pivoting movement. The magnetic force exerted by each magnet pair 411M, 421M of the opening holding mechanism 4A or 4B then acts parallel to the closing axis S and thus parallel to the y direction in the occupied operating position.

[0094] Even in Fig.19 and Fig.19AIn the embodiment variant, the operating elements 41.1, 42.1; 42.1, 42.2 are implemented to be rotated relative to each other at the opening mechanisms 4A and 4B of the closure parts 31 or 32, so that, for example, the first operating element 41.1 of the first closure part 31 is located with its supporting arm 425 below the supporting arm 425 of the second operating element 42.1 of the opening and holding mechanism 4A with respect to the vertical direction z, and the first operating element 41.2 of the first closure part 31 is located with its supporting arm 425 above the supporting arm 425 of the second operating element 42.2 of the other opening mechanism 4B. Therefore, the magnetic elements 411M on the base side are also positioned offset with respect to the vertical direction z with respect to the magnetic elements 421M on the supporting arm side of the same operating elements 41.1 to 42.2.

[0095] Fig. 20 and Fig. 20A Another embodiment variant of the locking device 2 is shown, in which the magnetic elements 41M, 42M on the operating element side of the opening mechanism 4A or 4B are at least partially shifted to overlap each other in order to shift the first and second locking sections 310 and 320 from the closed position to the open position. Here, the magnetic elements 41M and 42M of the opening mechanism 4A or 4B that act together are arranged in the head sections of the respective operating elements 41.1 to 42.2 that protrude laterally and are now disc-shaped. In the operating position, the magnetic force exerted by the magnetic element pairs 41M, 42M in order to lock the locking 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.

[0096] 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.
