DESCRIPTION OF THE INVENTION
[0100] FIGS. 1 to 9 are views of a first embodiment of a storage device 1, which device comprises a hollow body 10 which is bounded by walls 101, 102 and is configured to receive an object, in particular an electronic object such as a mobile telephone, or another object of daily life, for example a wallet or a payment means. For example, the storage device 1 can be a bag or a pouch. The storage device 1 can also be a liquid container, for example a hydration bladder. A liquid is then stored in the hollow body 10, which liquid can flow out via an outlet provided on the hollow body 10, e.g. into a drinking tube connected thereto.
[0101] The walls 101, 102 are interconnected at parallel side edges, remote from one another along a transverse direction x and transverse axis extending in parallel therewith, and at a lower edge along a vertical direction z, for example by welding, adhesive bonding or folding over at one of the mentioned edges, and are to be closed, in the region of an upper end, by a closure device 2 in such a way that an inner volume of the hollow body 10 or a cavity defined thereby is closed in a sealing manner in a closed position of the storage device 1. In principle, each wall 101, 102 can be formed by two layers, of which an inner layer faces towards the inner volume of the hollow body 10, and an outer layer faces towards the outside. The walls 101, 102 are configured to be flexible, such that the hollow body 10 is flexibly deformable, in particular in order to be able to flexibly receive an object therein or to be able to expand when a liquid is received in the hollow body 10.
[0102] The closure device 2 comprises three closure parts 31, 32, 33. Of these closure parts 31, 32, 33, a first closure part 31 is arranged on a closing portion 101S of the first wall 101, while a second closure part 32 is arranged on a closing portion 102S of the second wall 102, and specifically in such a way that the first and second closure parts 31, 32 extend along the vertical direction z at the same height on the respectively associated wall 101, 102. The closure parts 31, 32 interact in a magnetically attracting manner, such that, in the closed position of the closure device 2, the closing portions 101S, 102S, which are in each case formed by the inner layer of the associated wall 101S, 102S, rest flat, and thus in a sealing manner, against one another, and form a closure combination 3.
[0103] A third closure part 33 is arranged on a front side 101A of the wall 101, on a portion of the first wall 101 that is offset with respect to the closing portion 101S of the first wall 101, and, viewed along an extension path proceeding from the closing portion 101S, in the cross section according to FIG. 6, is arranged so as to be transversely offset with respect to the first closure part 31.
[0104] The closure parts 31, 32, 33 are in each case configured in a strip-shaped manner, and extend along the transverse direction x, and thus transversely to the vertical direction z.
[0105] The closure parts 31, 32, 33 are configured to interact in a magnetically attracting manner. In the embodiment shown, the closure parts 31, 32, 33 are in each case produced from a plastics material or a silicone material, in which a series of permanent magnets is embedded. In particular, discrete magnet elements 31M, 32M, 33M (of a magnet arrangement on the closure part side) can be arranged in one or more of the strip-shaped closure parts 31, 32, 33. In this case, the discrete magnet elements 31M, 32M, 33M are lined up along the transverse direction x, and thus form a linear array of magnet elements 31M, 32M or 33M. In this case, the closure parts 31, 32, 33 can have opposite poles, such that the closure parts 31, 32, 33 act on one another in a magnetically attracting manner, in pairs. In an alternative variant, opposite poles can also alternate in an array of magnet elements 31M, 32M or 33M of a closure part. An array of this kind is then provided for interaction with a corresponding opposing array on another closure part 32, 33, 31. The discrete magnet elements 31M, 32M, 33M of the magnet arrangements can in each case be formed by discrete permanent magnets, for example made of a neodymium material. It is also conceivable, however, for just one or two of the magnet arrangements to comprise discrete permanent magnets, while the other magnet arrangement(s) is/are formed of discrete ferromagnetically active elements.
[0106] Alternatively, for example just the first closure part 31 can act in a permanently magnetic manner, while the other closure parts 32, 33 are configured to be ferromagnetic, in particular as ferromagnetic armatures, such that the associated closure parts 32, 33 act as magnetic armatures. It is also conceivable, for example, for the first and second closure parts 31, 32 to be configured to be permanently magnetic, while the third closure part 33 acts ferromagnetically.
[0107] The closing portions 101S, 102S are pushed flat into contact with one another by the first closure part 31 and the second closure part 32, in the present case in such a way that the closing portions 101S, 102S formed by inner layers of the walls 101, 102 rest against one another in the manner of diaphragms and close the hollow body 10 in a sealing manner. The closure combination 3 formed by the closure parts 31, 32 is held in a defined closure position by the third closure part 33, wherein folding of the walls 101, 102 about 180 is brought about in a region between the closing portions 101S, 102S and the portions transversely offset relative to the closing portions 101S, 102S, as is clear from FIG. 1. As a result, the tightness of the closure device 2 in the closure position is further improved.
[0108] The first closure part 31 and the second closure part 32 in each case comprise an actuation portion in the form of a tab-like handle element 310, 320, on which a user can engage. By means of application of a force to the closure parts 31, 32, in particular on the handle elements 310, 320, the closure parts 31, 32 can be released from the further, third closure part 33 and adjusted into a release position. In said release position, the closure parts 31, 32 can be moved away from one another along an opening direction y (and thus at least in portions along a closing axis S in parallel therewith, which is oriented perpendicularly to the transverse axis x and to the vertical direction z), and thus the closing portions 101S, 102S can be separated from one another, such that the interior of the hollow body 10 is accessible via the opening O that is thereby released (cf. by way of example FIGS. 7 and 8A).
[0109] FIGS. 1 to 3 are various views of the storage device 1 having the closure device 2 in the closure position, in which the closure combination, formed by the first and second closure parts 31 and 32, is held in the closure position by means of the third closure part 33 on the front side 101A of the (first) wall 101. FIGS. 4-6 in turn show, in views corresponding to FIGS. 1 to 3, the storage device 1 having 2 the closure device in a folded-out release position. In said release position, the closure combination 3 is folded down from the third closure parts 33, such that the first and second closure parts 31 and 32 are displaceable away from one another, in order to release the opening O to the hollow body 10. FIGS. 7 to 9 show the storage device 1 having the closure device 2 and its first and second closure parts 31 and 32 in the open position. In this case, the views in FIGS. 7 to 9 are in each case rotated about 180 with respect to the views of FIGS. 4 to 6, such that for example FIGS. 7 and 8 each show a rear side 102B of the storage device 1, formed by the other, second wall 102.
[0110] In the open position, the two closure parts 31 and 32 are locked by two hold-open mechanisms 4A and 4B, such that the closure device 2 remains open, and thus the opening O remains accessible, without a user having to permanently apply a force manually to the closure parts 31 and 32. A hold-open mechanism 4A or 4B consequently applies an opening force which at least assists with the first and second closure parts 31, 32 assuming the open position and/or with the locking of the first and second closure parts 31, 32 in the open position. In the present case, a hold-open mechanism 4A or 4B is formed in each case, for this purpose, with two pairs of locking elements 41.1, 42.1 or 41.2, 42.2. In this case, the locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism are provided in each case spaced apart from one another in a rest position, in the closed position of the first and second closure parts 31 and 32 in accordance with FIGS. 4 to 6. When the closure parts 31 and 32 are displaced into the open position of FIGS. 7 to 9, the locking elements 41.1, 42.1 or 41.2, 42.2 are adjusted out of the rest position into a locking position, in which the open position of the closure parts 31 and 32 is locked by the locking elements 41.1 to 42.2, in pairs. For example, two locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A, 4B of the closure device 2 interact magnetically, in order to lock the closure parts 31 and 32 in the assumed open position and to apply a holding force which must first be overcome by a user in order to adjust the closure parts 31 and 32 towards one another again, along the closing axis S, and thus to close the closure device 2.
[0111] In this case, first locking elements 41.1 and 41.2 of the two hold-open mechanisms 4A and 4B are in each case associated with the first closure part 31 and are fixed or shaped thereon. In this case, the first locking elements 41.1 and 41.2 in each case protrude beyond ends of the respective strip-shaped closure part 31 of the x-axis, referred to as the transverse axis, along which the first closure part 31 extends. Thus, each first locking element 41.1, 41.2 protrudes beyond a respective lateral edge 101R of the associated closing portion 101S, and thus of the associated wall 101. Analogously, second locking elements 42.1, 42.2 of the hold-open mechanisms 4A, 4B, which are provided on the second closure part 32, also protrude laterally beyond ends of the second closure part 32 and lateral edges 102R of the other closing portion 102S, and thus of the other wall 102, of the storage device 1.
[0112] In a closed position of the first and second closure parts 31 and 32, corresponding to FIGS. 4 to 6, the laterally protruding locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A or 4B are angled and spaced apart from one another by a protruding portion, with respect to the transverse axis or the x-direction. When the first and second closure parts 31, 32 are transferred into their open position shown in FIGS. 7 to 9, the locking elements 41.1, 42.1 and 41.2, 42.2 are pivoted towards one another in pairs, and specifically about a pivot or hinge axis, in parallel with the vertical direction z, on the respective closing portion 101S or 102S. By means of the pivot movements associated with the opening of the closure device 2, the locking elements 41.1, 42.1 or 41.2, 42.2 of a respective hold-open mechanism 4A or 4B in each case bridge an adjustment path s, until the respective locking elements 41.1, 42.1 or 41.2, 42.2 have come into contact with one another and thus have assumed a locking position.
[0113] The assumption of said locking position is assisted by magnetic force. For this purpose, each locking element 41.1 to 42.2 comprises a magnet element 41M or 42M in the laterally protruding portion. In this case, the magnet elements 41M, 42M of a pair of locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A or 4B interact with one another in a magnetically attracting manner. Consequently, if the respective locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A or 4B are moved towards one another by a defined amount, by opening the closure device 2, the magnetic force applied by the magnet elements 41M, 42M is sufficiently great to automatically adjust the locking elements 41.1, 42.1 or 41.2, 42.2 towards one another, into the locking position visible in FIGS. 7 to 9.
[0114] The holding force applied by the hold-open mechanisms 4A, 4B is then also defined by the applied magnetic attractive force in the locking position, which holding force must be overcome on the user side in order to adjust the first and second closure parts 31 and 32 back in the direction of the closed position, and thus to close the opening O again. In this case, the holding force that is applied magnetically by the magnets 41M, 42M of a hold-open mechanism 4A or 4B acts substantially in parallel with the closing axis S, and thus along the y-axis or in parallel with the y-direction.
[0115] In the case of the storage device shown in FIGS. 1 to 9, an elongate locking element 41.1-42.2 is provided on a respectively associated first or second closure part 31 or 32, without in this case extending over the entire length of the respective closure part 31 or 32, and thus additionally stiffening the respective closure part 31 or 32, apart from a respective lateral end of the respective closure part 31 or 32. Furthermore, in the present case the closure parts 31 and 32 are in each case formed from a material that is inherently non-flexible or at least flexible only to a certain extent, in particular in order to assist with flat contact of the closing portions 101S, 102S in the closed position of the first and second closure parts 31 and 32, in particular in order to assist with sealing contact of the closing portions 101S and 102S. In order to ensure a bulge of the closure parts 31 and 32 as well as of the third closure part 33 when opening the storage device 1, in each case weakening regions in the form of notches K are provided purposely on the closure parts 31, 32, 33. In the region of the respective notches K, the material of which the respective closure part 31, 32 or 33 is formed is purposely reduced, such that portions of the respective closure part 31, 32 or 33 are connected in an articulated manner via a notch K in the manner of a film hinge, and thus so as to be displaceable relative to one another.
[0116] In a variant, it is also possible for a plurality of separate (smaller or shorter) closure parts to be provided in a manner separated from one another in the transverse direction. Said closure parts would then be completely separated from one another in the region of a notch K. In this case, however, a more flexible region of a respective closing portion 101S or 102S or the wall 101 or 102 forming the respective closing portion, could act as a film hinge.
[0117] In a further variant of FIGS. 10 to 18, alternatively configured hold-open mechanisms 4A and 4B are provided. If, here or in the figures explained in greater detail in the following, identical reference signs are used, these also refer to identical components and functional elements.
[0118] For example, the variant of FIGS. 10 to 18 again provides a pair of locking elements 41.1, 42.1 or 41.2, 42.2 in each case, for each hold-open mechanism 4A and 4B, via which locking elements the closure parts 31 and 32 are locked in their open position. Here, too, the locking elements 41.1, 42.1 or 41.2, 42.2 interact in pairs, in a magnetically attracting manner, in order to lock the open position of the closure parts 31 and 32. In contrast to the variant of FIGS. 1 to 9, in this case, in a locking position, magnetic forces of magnet elements 411M, 422M; 412M, 421M on the locking element side act along an effective axis extending perpendicularly to the closing axis S and thus in parallel with the vertical direction z. Thus, in the case of a displacement of the first and second closure parts 31, 32 out of their closed position into the open position, the corresponding magnet elements 411M, 422M and 412M, 421M are then also displaced beyond one another at least in part, until the respective locking position is assumed. For example, in each case one first magnet element 412M or 422M of a locking element is then arranged on an end of the respective closure part 31 or 32, on a portion of the respective locking element that surrounds the respective lateral edges 101R, 102R at least in part. A second magnet element 411M or 421M, with which the first magnet element 422M or 412M interacts, in a magnetically attracting manner, in the locking position for locking the open position, is provided so as to be spaced apart therefrom, on the respective other locking element. In this way, a sufficiently high magnetic attractive force for automatically transferring the locking elements 41.1, 41.2 or 41.2, 42.2 further into the locking position and for holding them in the locking position acts between the first and second magnet elements 412M, 421M and 422M, 411M only by means of a displacement of the locking elements 41.1, 41.2 or 41.2, 42.2 in the direction of the locking position.
[0119] In this case, the first magnet elements 412M, 422M of the locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A, 4B, which magnet elements are arranged on the partially surrounding and thus projecting portions, can also be polarized opposingly to one another, such that the first magnet elements 412M, 422M, in the closed position of the closure parts 31 and 32, assist with holding the locking elements in the rest position.
[0120] The first or second locking elements 41.1, 41.2 (for the first closure part 31) or 42.1, 42.2 (for the second closure part 32), which are associated with a closure part 31 or 32, are configured to be offset from one another in the present case. That is to say that a first locking element 42.1 on the first hold-open mechanism 4A is positioned and pivotable under the second locking element 42.1, based on the vertical direction z, while the first locking element 41.2 on the other hold-open mechanism 4B is arranged and pivotable above the second locking element 42.2 there.
[0121] In particular in a development of the variant of FIGS. 10 to 18, a hold-open mechanism 4A and/or a hold-open mechanism 4B can additionally integrate a latching device, by means of which the locking position assumed by a respective pair of locking elements 41.1, 42.1 or 41.2, 42.2 is additionally secured. For this purpose, a displaceably mounted latching pin (or another form-fitting connection element) is then provided for example on one of the locking elements, which pin can plunge in a form-fitting manner into a latching opening or a latching hole of the other locking element, at least in part, when the locking position is reached. If the locking elements are intended to be adjustable again, relative to one another, and thus the closure parts 31, 32 are intended to be adjustable out of the open position, first of all the latching pin must be pushed or pulled out of the latching opening or the latching hole. Instead of a latching pin in combination with a latching opening or a latching hole, other latching components can of course also be provided (of which at least one is adjustably mounted), by means of which in particular form-fitting and/or force-fitting latching of two locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A, 4B can be achieved.
[0122] The variant of FIGS. 19 to 27 provides hold-open mechanisms 4A, 4B of the closure device 2 in which locking of the closure parts 31 and 32 in their open position takes place not magnetically, but rather purely mechanically. For this purpose, in each case a first locking element 41.1 or 41.2 engages, with a laterally protruding guide web 413, into a curved guide channel 423 of a second locking element 42.1 or 42.2 of the respective hold-open mechanism 4A or 4B. The guide web 413 is guided in the respective guide channel 423, in the case of a displacement of the locking elements 41.1, 42.1 or 41.2, 42.2 out of their rest position and into the locking position. In this way, when the locking position is assumed, a latching element configured in the form of a latching lug 424 on a guide channel wall of the respective guide channel 423 can latch in a form-fitting manner into a latching opening, configured as a latching groove 414, of the associated guide web 413 as soon as the locking position is assumed. Thus, in the variant of FIGS. 19 to 27, the open position of the first and second closure parts 31 and 32 is locked by mechanical latching of the two locking elements 41.1, 42.1 or 41.2, 42.2 of a respective hold-open mechanism 4A and 4B.
[0123] If a sufficiently high actuating force is applied in order to displace the latching lugs 424 out of their respective latching grooves 414, the locking is released and the closure parts 31 and 32 can be brought back into their closed position, along the closing axis S.
[0124] In the variant of FIGS. 28 to 36, each locking element 41.1 to 42.2 is equipped with two magnets 411M, 412M or 421M, 422M in each case, in order to lock the open position of the closure parts 31 and 32 in a manner assisted by magnetic force. In this case, each locking element 41.1 to 42.2 in each case comprises a support arm 425, which in each case surrounds the lateral edges 101R, 102R in part, on a long side of the storage device 1. In each case a first magnet element 412M or 421M is provided on said support arm 425. Upon transfer of the first and second closure parts 31, 32 into the open position, and thus opening of the closure device 2, the respective support arm 425 is brought into contact with a base 426 of the respective other locking element, by performing a pivot movement. A magnetic force applied by a magnet pair 412M, 422M or 411M, 421M, in each case, of a hold-open mechanism 4A or 4B then acts, in the assumed locking position, at an angle relative to the closing axis S and thus at an angle relative to the y-direction, in the present case e.g. at an angle of approximately 45. However, in this embodiment the magnetic force then acts again (as e.g. also in the embodiment of FIGS. 1-9) in a normal plane with respect to a hinge axis, about which the respective locking element 41.1 to 42.2 is pivotable out of the rest position and into the locking position.
[0125] In the case of the variant of FIGS. 28 to 36, too, the locking elements 41.1, 42.1; 42.1, 42.2 on the hold-open mechanisms 4A and 4B of a closure part 31 or 32 are configured to be twisted relative to one another, such that for example a first locking element 41.1 of the first closure part 31 rests on one hold-open mechanism 4A, with respect to the vertical direction z, having its support arm 425 under the support arm 425 of the second locking element 42.1 of said hold-open mechanism 4A, while the first locking element 41.2 of the first closure part 31 rests on the other hold-open mechanism 4B having its support arm 425 above the support arm 425 of the second locking element 42.2 of the other hold-open mechanism 4B. Thus, a base-side magnet element 411M or 421M in each case is then also positioned so as to be offset in each case, relative to a carrier arm-side magnet element 412M or 421M of the same locking element 41.1-42.2, based on the vertical direction z.
[0126] In a deviation from the variant shown in FIGS. 28 to 36, it is of course also possible for a locking element 41.1-42.2in the present case L-shaped in cross sectionto be provided on an opening mechanism 4A or 4B merely on one of the first or second closure parts 31, 32, which locking element is pivotable about a hinge axis in parallel with the spatial direction z, when the closure parts 31, 32 are displaced into their open position. A locking element which interacts with the pivotable locking element and by means of which the open position is then locked can then be formed for example merely by an end portion of a closure part 32, 31 which is opposite the closure part 31 or 32 comprising the pivotable locking element. Consequently, the respective closure part 32 or 31 comprises an integrated locking element comprising the magnet element 411M, with which a magnet element 421M (integrated in the support arm 425) of the pivotable locking element interacts in the locking position.
[0127] FIGS. 37 to 45 show a further variant of a closure device 2, in which locking element-side magnet elements 41M, 42M of a hold-open mechanism 4A or 4B are in each case displaced beyond one another, at least in part, in the case of an adjustment of the first and second closure parts 31 and 32 out of the closed position and into the open position. In this case, magnet elements 41M and 42M of a hold-open mechanism 4A or 4B, which interact with one another, are arranged in a head portion of the respective locking element 41.1-42.2, which head portion in each case projects laterally and in the present case is disc-shaped. Then, in the locking position, a magnetic force applied by a magnet element pair 41M, 42M for locking the closure parts 31 and 32 in their open position again acts perpendicularly to the closing axis S and thus in parallel with the vertical direction z.
[0128] The variant of FIGS. 46 to 54 is a development of the variant of FIGS. 1 to 9. In this case, the hold-open mechanisms 4A and 4B are configured identically. In a deviation from the variant of FIGS. 1 to 9, however, no handle elements 310, 320 are provided on the first and second closure parts 31 and 32, via which handle elements a user can engage on the first and second closure parts 31, 32, in order to adjust the closure parts 31 and 32 between the closed position and the open position. Rather, the variant in FIGS. 46 to 54 provides that the locking elements 41.1-42.2, in each case optionally formed integrally with an associated closure part 31 and 32, are also provided for manual application of an operating force thereon, in order to adjust the closure parts 31 and 32 out of the closed position, shown in FIGS. 49 to 51, and into the open position. Thus, moving together, and associated pivoting, of the locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A or 4B in the direction of their locking position automatically results in the first and second closure parts 31 and 32 being pushed away from one another in their central region. The locking elements 41.1, 42.1 or 41.2, 42.2 of a hold-open mechanism 4A or 4B thus in each case form operating portions for manual force application, such that the first and second closure parts 31 and 32-in the case of a closure combination 3 present in the release position-can be adjusted out of their closed position and into the open position by displacement of the respective first and second locking elements 41.1, 42.1 or 41.2, 42.2 out of their rest position in the direction of the locking position.
[0129] In order to assist such operation of the closure device 2, the strip-shaped closure parts 31, 32 (as well as the third strip-shaped closure part 33) can be produced for example from a resilient material having discrete magnet elements 31, 32 or 33 embedded therein, or from a resilient, magnetic material.
[0130] In a development according to FIGS. 55 to 60, in contrast to the variant of FIGS. 46 to 45 all that is intended is to provide a flexibility or elasticity, required for the bulging of the first and second closure parts 31 and 32 in the case of an adjustment into the open position, not (only) by the material used for the first and second closure parts 31 or 32. Rather, in this case a plurality of notches K extending in parallel with the vertical direction z is provided on each first and second closure part 31, 32. Consequently, in this case the first and second closure parts 31 and 32 are segmented via the notches K. The individual magnet elements 31 or 32 of the closure parts 31, 32 are then arranged in one of the segments in each case.
[0131] In the present case, the elongate locking elements 41.1-42.2 are provided on the end side, on the respective first and second closure part 31, 32. In this case, for example analogously to the embodiment of FIGS. 1 to 9 explained above, a respective locking element-side magnet element 41M or 42M on a portion of the respective locking element 41.1-42.2 that is angled away from the respective closure part 31 or 32, and thus with respect to the transverse axis or the x-direction, in the closed position.
[0132] FIGS. 61 and 62 are perspective views of a storage device 1 according to FIGS. 46 to 54, illustrating the use of the locking elements 41.1-42.2 of the hold-open mechanisms 4A, 4B for opening the closure device 2. In this case, FIGS. 61 shows the storage device 1 having the closure device 2 in the release position, and the first and second closure parts 31 and 32 in the closed position. In this case, a hand H of a user engages with two fingers F1 and F2in the present case thumb and forefingeron the locking elements 41.2 and 42.2 of the hold-open mechanism 4B. By being pressed together, the locking elements 41.2, 42.2 are moved towards one another, in accordance with FIG. 62, bridging the adjustment path s and thus the spacing between the two protruding portions of the locking elements 41.2 and 42.2, such that they come into contact with one another. The pivot movement of the locking elements 41.2, 42.2, caused thereby, is associated with the first and second closure parts 31 and 32 being pushed away from one another at the edge of the opening O, such that the first and second closure parts 31 and 32 are transferred into the open position and the cavity 10 becomes accessible via the opening O. On account of the magnetic forces applied by the magnet elements 41M and 42M of the hold-open mechanisms 4A and 4B, the first and second closure parts 31 and 32 remain in the open position, even if the user removes their hand H from the closure device 2.
[0133] FIG. 63 shows a possible development of the variant of FIGS. 19 to 27, in which an additional unlocking element in the form of an actuation loop 51, 52 is also provided, on each of the hold-open mechanisms 4A, 4B. For example, in a variant of FIGS. 19 to 27, a latching connection comprising the latching lug 424 and the latching groove 414 can in principle be configured such that, in the case of a manually applied force on the closure parts 31 and 32 present in the open position, the latching is released without destruction, and thus the locking is also released. In a possible development, however, it can also be provided, in accordance with FIG. 63, that the corresponding form-fitting latching first has to be released separately by means of a prior, additional force application on the respective hold-open mechanism 4A, 4B. Thus, for example in the present case, it may be necessary to pull on the actuation loop 51 or 52. Said actuation loop 51, 52 is in each case connected to the portion of a locking element 41.1 or 42.2 forming the latching lug 424, such that the latching lug 424 can be brought out of engagement with the respective latching groove by the force application.
[0134] Instead of the actuation loop 51 or 52 shown, of course an unlocking element configured in a different manner can also be provided, for example a rigid ring.
[0135] Alternatively or in addition to the variants explained above, it can also be provided, however, for the first and second closure parts 31 and 32 to be held in the open position by an additional element, for example by a rod attached to the inside of the closure parts 31,32.
[0136] Alternatively or in addition, the closure device 2 can also be configured having a deceleration means. A deceleration means of this kind is then configured to temporally limit the locking in the open position, following a completed transfer of the closure parts 31 and 32 into the open position, before the closure parts 31 and 32 are displaced automatically back into the closed position again, for example under action of a corresponding preload, e.g. a resilient preload, in the direction of the closed position. For example, a corresponding deceleration means can comprise one or more deceleration elements, e.g. in the form of suction cups and/or adhesion elements. Corresponding deceleration elements of the deceleration means can thus apply a holding force that decreases over time. Corresponding deceleration elements can be provided for example on laterally protruding portions of the locking elements 41.1, 42.1 or 41.2, 42.2 which are brought into locking contact with one another with transfer of the locking elements 41.1, 42.1 or 41.2, 42.2 into the locking position, or of the closure parts 31 and 32 into the open position. The holding force applied via said contact then reduces continuously however, or suddenly after a predefined time period has elapsed, if no further force is applied, by the user, to the respective hold-open mechanism 4A or 4B. The first and second closure parts 31 and 32 are thus automatically adjusted back into the closed position as soon as a corresponding restoring force is greater than the decreasing holding force.
[0137] FIGS. 64A-64B, 65A-65D and 66A-66C show a further variant of a pouch-shaped storage device 1 comprising a variant of a proposed closure device 2. In this case, the storage device 1 of FIGS. 64A to 66C is configured as a pouch or bag, which can be worn by a person on the back 102B, via a waist belt 7. An actuation tab 6 is provided on the front side 101A, on the closure device 2. By pulling the actuation tab 6, the closure combination 3 of the closure device 2 can be pulled out of the closure positioncounter to the magnetic force applied by the third closure part 33and into the release position (cf. FIGS. 65A to 65C) and, in the assumed release position, the first and second strip-shaped closure parts 31 and 32 can be transferred into their open position (cf. FIGS. 65D to 65E).
[0138] In this case, the ends of the actuation tab 6 are fixed on the front side 101A, in the region of the third closure part 33, in order to overcome the respective magnetic forces by manually pulling on the actuation tab 6, applying a comparatively low manual force, and thus be able to easily open the storage device 1 on the closure device 2.
[0139] As is illustrated on the basis of FIGS. 66A to 66C, the closure device 2 that is held open by a proposed hold-open mechanism can also be easily closed again, in that the first and second closure parts 31 and 32 are moved sufficiently close to one another in their central region, such that they assume their closed position. Subsequently, the closure combination 3 is folded over, in the closure position, in the direction of the third closure part 33.
[0140] The possibility for simple one-handed opening of the storage device 1, illustrated by the actuation tab 6 (or another handle-like or tab-like actuation element) in the variant of FIGS. 64A to 65E, is furthermore also in principle advantageous without the first and second closure parts 31 and 32 being held in an open position via a hold-open mechanism. For example, the storage device 1 can be opened by a user with a flowing movement-over different movement phases-via the actuation tab 6. By means of pulling on the actuation tab 6, firstly the closure combination 3 can be folded out of the magnetically held closure position and into the release position. Subsequently, in the release position the first and second closure parts 31 and 32, which are held magnetically against one another, can be separated from one another via the actuation tab 6, and transferred out of the closed position and into the open position. Maintaining the open position via a hold-open mechanism can additionally be advantageous in this connection, but is merely optional.
[0141] In a deviation from the storage device 1 shown in FIGS. 64A to 65E, it is furthermore not necessary for a user to engage on the rear side 102B when the storage device 1 has been fixed via the waist belt 7. Instead of a waist belt 7, another type of fastening can furthermore also be provided.
[0142] FIGS. 67A to 69C are various views of a further variant of a pouch-shaped storage device 1 comprising a variant of a proposed closure device 2, which, when the closure device 2 is open, holds the closure device 2 in an open state via a hold-open mechanism.
[0143] In the case of the storage device 1 of FIGS. 67A to 69C, once again an actuation tab 6 is provided on the front side 101A of the storage device 1. In this case, ends of the actuation tab 6 are in each case fastened on an intermediate space between a centrally arranged third closure part 3 and a further third closure part 331 or 332 that is adjacent thereto in each case. In this case, the three third closure parts 331, 33 and 332 are in each case configured in a strip-shaped manner and are provided in succession along the transverse axis.
[0144] As is illustrated in particular on the basis of the partial perspective plan view of FIG. 67C and the enlarged details of FIGS. 68A and 68B, the storage device 1 of FIGS. 67A to 69C comprises a hold-open mechanism 4 having an inner flexible locking element in the form of a (resilient) tensioning cable 40. An intermediate wall 40A is provided in the interior of the storage device 1, by which intermediate wall the inner cavity of the storage device 2 is divided into two compartments I1 and I2, in the present case of approximately the same size. On an upper edge facing the opening O that can be closed by the closure device 2, and thus in the region of an upper edge of the intermediate wall 40A, the tensioning cable 4 is guided inside the intermediate wall 40A. Two mutually opposing (longitudinal) edges of the storage device 1 are connected to one another and preloaded towards one another via the tensioning cable 40, in the interior of the storage device 1. A corresponding tensioning force applied by the tensioning cable 40 then also acts on the first and second closure parts 31, 32, which are interconnected at their ends at said lateral longitudinal edges, such that the first and second closure parts 31, 32 are preloaded into their open position via the tensioned tensioning cable 40. Thus, under action of the tensioned tensioning cable 40 the central region of the first and second strip-shaped closure parts 31 and 32 are pushed outwards, when the magnetic forces, by which the first and second closure parts 31, 32 are held against one another in the closed position, are overcome manually.
[0145] In order to optionally re-tension the tensioning cable 40 and thus be able to readjust a tensioning force applied thereby, a cable portion, here in the form of a cable loop, is guided out of the intermediate wall 40A. When the storage device 1 is open, said cable portion is manually accessible for a user, in accordance with FIG. 68B. A user can then pull on the cable portion with one hand, in order to more strongly tension the tensioning cable 40. In this case, the cable portion that is pulled further out of the intermediate wall 40A by the pulling can be locked via a cable locking means 400, for example in the manner of a cord clamp, in order to maintain the readjusted cable tension. The storage device 1 is closed in accordance with FIGS. 69A to 69C, by approaching the first and second closure parts 31 and 32 towards one another, counter to the tensioning force applied by the tensioning cable 40.
[0146] In the variant of a storage device 1 in accordance with FIGS. 70A and 70B, above all the volume of the storage device 1 is configured differently. This can therefore be, for example, a smaller pouch or a smaller bag. An inner tensioning cable 40 is also provided here as a part of the hold-open mechanism 4, which cable extends in an intermediate wall 40A and can be re-tensioned via a cable locking means 400.
[0147] In a variant of a storage device 1 of FIGS. 71A to 71C, the third closure part 33, via which the closure combination 3 can be magnetically held in the closure position, is not provided on the front side 101A, but rather is arranged within the storage device 1. Furthermore, the third closure part 33 is configured in a divided manner in this case, such that it is formed by two elongate portions which, in the present case, can act as locking elements 330 and 331 of a hold-open mechanism 4 for the open position.
[0148] The two elongate locking elements 330 and 331 of the third closure part 33 directly adjoin one another in the closed position of the first and second closure parts 31, 32 (both in the closure position and in the release position). Thus, the closure combination 3 can be held in the closure position, as has already been explained above, by means of magnet elements arranged in the locking elements 330, 331 of the third closure part 33, and their magnetic interaction with the magnet elements of the first closure part 31.
[0149] When the closure device 2 of a storage device 1 of FIGS. 71A to 71C is opened, the two strip-shaped locking elements 330 and 331, which are in each case connected to a left-hand edge of the storage device, are how displaced relative to one another, however, such that they overlap one another, in accordance with FIG. 71B. In a resulting overlap region UB, in which portions of the locking elements 330 and 331 are opposite one another in an overlapping manner, the magnet elements of the first and second locking elements 330 and 332 act on one another in an attractive manner, such that an overlapping position of the locking elements 330 and 331 is retained. The locking elements 330 and 331 of the third closure part 33, which magnetically attract one another in the overlapping position, thus hold the longitudinal edges of the storage device 1 in a position in which they have been moved towards one another, and thus the first and second closure parts 31, 32, in the currently assumed open position.
[0150] If the closure device 2 is opened further, in that the first and second closure parts 31 and 32 are bulged further outwards, the two locking elements 330 and 331 of the first closure part 33 are thereby shifted relative to one another. The overlap region UB enlarges. This is then also retained in a further opened position, by means of the magnet elements in the overlapping portions of the locking elements 330, 331, which elements attract one another. Closing is possible only by overcoming the magnetic forces, in order to separate the locking elements 330, 331 from one another.
[0151] A hold-open mechanism 4 of FIGS. 72A and 72B is based on a comparable principle. In this case, a hold-open mechanism 4 is provided in the interior of a storage device 1, which hold-open mechanism comprises two locking elements 41.1 and 42.1 which are spaced apart from one another in the closed position of the first and second closure parts 31 and 32. In each case a magnet element 411M or 421M is provided on end pieces of the two inner locking elements 41.1 and 42.1 that face one another. If the two end pieces of the two locking elements 41.1 and 42.1, which end pieces carry the respective magnet elements 411M and 421M, are moved closer to one another upon opening the closure device 2, a connection between the two locking elements 41.1 and 42.1 is established by the magnetic attraction of the two magnet elements 411M and 421M. The interconnected locking elements 41.1 and 42.1 then exert a holding force on the longitudinal edges of the storage device 1, and thus on the first and second closure parts 31, 32 in their open position. A transfer of the first and second closure parts 31, 32 into their closed position is possible only by overcoming the holding force, such that the two locking elements 41.1 and 42.1, which are magnetically fixed to one another, are separated from one another again.
[0152] In the variant of a storage device of FIGS. 73A and 73B, a hold-open mechanism 4 comprising a U-shaped tensioning element, here in the form of a spring element 8, is provided. Said U-shaped spring element 8 extends with a base 8.3 along a lower edge of the storage device 1. Two mutually opposing limbs 8.1 and 8.2 are interconnected via the base 8.3 and extend along the longitudinal side edges of the storage device 1, here within a peripheral edge portion R of the storage device 1. The two limbs 8.1 and 8.2 are preloaded towards one another (cf. also FIG. 73B). In this case, the limbs 8.1, 8.2 end in the region of the upper edge of the storage device 1 that bounds the opening O, such that the preload force of the two limbs 8.1, 8.2 is also transferred to the two closure parts 31 and 32, here in each case again strip-shaped. In this way, the first and second closure parts 31 and 32 strive to bulge outwards in their open position, under action of the preload of the limbs 8.1 and 8.2. In this case, moving the first and second closure parts 31 and 32 closer together in order to assume their closed position is possible only counter to the preload force applied by the limbs 8.1, 8.2, and thus a corresponding holding force. Consequently, after the closure device 2 has been opened, the open position is maintained under action of the two limbs 8.1 and 8.2.
[0153] The same also applies for a variant according to FIGS. 74A and 74B. In this case, a hold-open mechanism 4 comprising two spring (steel) strips 43.1 and 43.2 is provided. The spring strips 43.1 and 43.2 extend, in the present case, along a respective associated closure part 31 or 32, or are an integral component of the respective closure part 31 or 32. In this case, a first spring strip 43.1 is associated with the first closure part 31, while a second spring strip 43.2 is associated with the second closure part 32. Each spring strip 43.1 or 43.2 is preloaded into a bulge direction, and specifically, in the present case, in such a way that the strip-shaped closure parts 31 and 32 are preloaded to an outward bulge in their central region, under action of the spring strips 43.1 and 43.2. Consequently, in order to close the closure device 2 such that the first and second closure parts 31 and 32 assume their closed position, a user must push the central regions of the first and second closure parts 31 and 32 towards one another, counter to the spring forces of the two spring strips 43.1 and 43.2.
[0154] A similar principle is provided in the storage device FIGS. of 75A to 75B. In this case, two spring strips 43.1 and 43.2 are provided as part of two hold-open mechanisms 4A, 4B. A first spring strip 43.1 extends between two, in FIG. 75A left-hand, longitudinal ends of the first and second closure parts 31 and 32. The other spring strip 43.2 in turn extends between two other, right-hand, longitudinal ends of the first and second closure parts 31 and 32.
[0155] The first and second spring strips 43.1 and 43.2 in each case strive to align themselves straight and thus in a manner preloaded into a state in which a respective spring strip 43.1 or 43.2 extends 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 (centrally) and held in this state, bent once, via the magnetic forces of the first and second closure parts 31 and 32 that magnetically attract one another. If said magnetic force is overcome manually, the spring strips 43.1 and 43.2 fold out automatically on account of their respective preload, and thus displace the first and second closure parts 31, 32 into their open position and hold the first and second closure parts 31, 32 in a manner spaced apart from one another, in the open position (cf. FIG. 75B).
[0156] Hold-open mechanisms 4A, 4B corresponding to FIGS. 75A and 75B can be used for example in a storage device of FIGS. 76A and 78B. Said storage device 1 is configured as a rucksack which can be carried on a back by means of two carrying straps T1 and T2.
[0157] In a closed state, two mutually opposing walls of the rucksack 1 of FIGS. 76A to 78B are folded or rolled in. This rolled-together closure position is secured via a closure 9, in accordance with FIGS. 76A to 76C. For this purpose, a securing component 90 interacts with a mating part 91 of the closure 9, on the front side 101A of the rucksack 1. If an optionally magnetically assisted latching between the securing part 90 and the mating part 91 is released, in accordance with FIGS. 77A to 77C the rucksack 1 can be unrolled on its upper side, and as a result the closure device 2 with the closure combination 3 can be transferred into the release position. In the release position, the two first and second closure parts 31 and 32, which are held magnetically in the closed position, can be transferred manually into the open position.
[0158] In the open position, the closure parts 31 and 32 are held via hold-open mechanisms comprising spring strips 43.1, 43.2. Only after overcoming a holding force applied by the spring strips 43.1 and 43.2 can the two first and second closure parts 31 and 32 consequently be moved towards one another again, and thus be transferred into their closed position.
[0159] The concept on which the proposed solution is based is not limited to the embodiments set out above, but rather can also be implemented in an entirely different manner.
