Definitions

  • the proposed solution relates to a closure device for closing an opening formed between a first closing section and a second closing section.
  • the locking sections can be part of a storage device.
  • a cavity in a hollow body of the storage device can then be closed via the opening closed using the locking device.
  • Such a storage device is intended, for example, to hold an object, for example an electronic object such as a mobile phone, a camera on a tablet or laptop computer or the like, or another object of everyday life, for example a wallet or a means of payment such as a credit card.
  • Such a storage device serves to hold and protect objects, in particular from moisture or dirt or other external influences. This should make it possible to carry the objects in difficult environments, for example when doing water sports, but also at work, for example.
  • Such a hollow body then has a cavity, for example formed between a first wall and a second wall, in which the object to be accommodated in the storage device can be stored.
  • the closure device is then provided, which comprises a first closure part and a second closure part.
  • the first closure part has a first strip body that extends longitudinally along a transverse direction and is arranged on a first closure section of the first wall
  • the second closure part has a second strip body that extends longitudinally along the transverse direction and is arranged on a second closure section of the second wall.
  • the first closure part and the second closure part act together in a magnetically attractive manner such that in a closed position in which the hollow body is closed, the first closure section and the second closure section abut one another.
  • a storage device is known, for example, from EP 2 571 391 B1 known.
  • the first and second closure parts form a closure assembly in a closed position of the closure device, which can be adjusted from a release position to a closed position.
  • the first and second closing sections can be separated from one another again as intended, counter to a magnetic force applied by the first and second closure parts, in order to release the opening.
  • the closure assembly and a third closure part interact in a magnetically attractive manner such that the closure assembly is held in the closed position in which it is not possible to release the opening.
  • the closure assembly must therefore first be adjusted from the closed position to the release position in order to release the opening again.
  • the closure assembly can be adjusted to the closed position, for example, by folding or rolling up the closure assembly at least once, so that the closure assembly is then held in a folded or rolled up closed position with the help of the third closure part.
  • the magnetic safety device between the locking assembly and the third locking part effectively protects the locking device against unintentional opening by the user and allows comparatively easy handling guaranteed, there is a need for further improvement in such a closure device.
  • increased loads on the closure device for example due to increased internal pressure in a cavity closed by the closure device, (increased) shear forces can occur on the closure parts of the closure device, which may cause the closure assembly to be removed from the third closure part and/or the first and second closure sections to be separated from one another.
  • a closure device according to claim 1 represents an improvement in this respect over the solutions known from the prior art.
  • a proposed locking device comprises an additional securing mechanism by which the locking assembly present in a locking position is additionally secured against removal from a locking position.
  • the closure device additionally comprises a third closure part on a first closure section, with which the closure assembly interacts in a magnetically attractive manner in its closed position.
  • the closed position can then be additionally secured mechanically via the additional securing mechanism, so that the securing mechanism prevents the closure assembly from being accidentally removed from the third closure part.
  • a closure device in which the closing sections can be adjusted into the closed position by folding or rolling them at least once and the securing mechanism secures the closure assembly against removal from the closed position it has assumed in this way due to an increased internal pressure in a hollow body closed by the closure device at the opening.
  • a proposed closure device (also independent of a third closure part that interacts with the closure assembly in a magnetically attractive manner) has proven to be advantageous in order to secure a closed position assumed by folding or rolling them at least once against undesired opening when shearing and/or lifting forces act on the first and second closure parts as a result of an increased internal pressure on a hollow body closed by the closure device.
  • An additional securing mechanism can be used to effectively counteract in particular shear forces which act in a central section of the strip bodies of the first and second closure parts in a direction perpendicular to a longitudinal extension of the strip bodies and/or lifting forces which act on the longitudinal end side of the closure assembly and under the effect of which the closure parts tend to move away from one another.
  • the securing mechanism can therefore be designed in particular to counteract a shear force acting between the first and second closure parts, between the closure assembly and a third closure part or between the closure assembly and a wall opposite which the closure assembly is located in the closed position.
  • the proposed solution is based on the basic idea of additionally mechanically securing the locking assembly with the locking sections that are adjacent to one another in the closed position in its closed position against displacement into the release position, at least as long as no release force applied by the user acts on the locking assembly along a specific, predetermined direction of action.
  • This can prevent the locking assembly from being opened unintentionally.
  • the additional securing mechanism can thus be operated manually and thus released in order to be able to adjust the locking assembly back into the release position.
  • the locking assembly remains locked against being adjusted into the release position.
  • the first and second locking parts with their strip bodies thus provide a (possibly sealing) closure on the locking sections, which is mechanically secured by the securing mechanism.
  • Removal from the Locking position against which a mechanical safeguard is provided via the safety mechanism, is therefore understood not only to mean accidental removal by an active user-side attack on the locking device, but in particular (at least partial) removal from the locking position which is due to a load acting on the locking device which is not applied by the user.
  • the first and second closing sections can be folded or rolled up, in particular in that the first and second closing sections and thus the walls comprising the closing sections are bent at least once by 180°, viewed along an extension path in cross section perpendicular to the transverse direction.
  • the strip bodies are arranged on the closing sections and thus act on the closing sections, whereby the closure parts interact in a magnetically attractive manner and the closing sections are thus held magnetically in contact with one another when the first and second closure parts are in their closed position.
  • the first strip body and/or the second strip body can each be formed from a magnetic material, for example by forming the strip bodies from a plastic material, in particular a polymer material, or a silicone material to which a magnetic material in the form of magnetic particles is added.
  • the strip bodies can each accommodate a magnet arrangement made of discrete magnetic elements, so that the strip bodies interact in a magnetically attractive manner through the interaction of the magnet arrangements.
  • each closure part has a permanent magnetic effect, for example by forming the strip bodies with permanent magnetic particles and thus being made from a permanent magnetic material, or by forming the magnet arrangements of the closure parts from an arrangement of permanent magnets.
  • one closure part is also possible for one closure part to be permanently magnetic and the other closure part to act as a ferromagnetic anchor, for example by the ferromagnetically acting closure part having a strip body made of a ferromagnetic material (for example a plastic material to which ferromagnetic particles are added) or having discrete ferromagnetic elements.
  • a ferromagnetic material for example a plastic material to which ferromagnetic particles are added
  • a closure part has a magnet arrangement made up of discrete magnetic elements
  • the discrete magnetic elements can be arranged in a linear fashion along the transverse direction, for example, whereby the discrete magnetic elements can be regularly spaced apart from one another along the transverse direction, for example.
  • a third closure part can also have a third strip body extending along the transverse direction.
  • the third closure part is arranged on an offset section of a first wall that is different from the first closure section.
  • the third closure part can, for example, interact with the first closure part in a magnetically attractive manner in order to hold the closure assembly in the closed position.
  • the third closure part can be arranged spatially offset from the first closure section perpendicular to the transverse direction.
  • the third closure part is thus designed with its third strip body extending parallel to the first strip body of the first closure part, but offset transversely to the first closure part.
  • the third strip body and the first strip body can be in a flat position opposite one another, for example with their surfaces facing one another.
  • the closure parts interact in a magnetically attractive manner, so that the first closure part is held in a defined positional relationship to the third closure part.
  • first strip body and/or the second strip body and/or a third strip body of a third closure part are designed to be elastic.
  • a strip body can have increased rigidity compared to walls of a hollow body on which the closure device is inserted, for example, but is so elastic that it can be bent, in particular about a vertical direction perpendicular to the transverse direction.
  • the securing mechanism can provide an additional connection between the closure assembly and a wall connected to the first closure section and/or between the closure assembly and the third closure part when the closure assembly is in the closed position.
  • a connection between the closure assembly and the third closure part includes, for example, that in the closed position a connection is provided between the first closure part and the third closure part or between the second closure part and the third closure part via the securing mechanism.
  • the additional connection provided via the securing mechanism can be positively locking and designed to absorb shear forces acting on the closure device.
  • the securing mechanism has at least one securing part that secures the locking assembly against removal from the third locking part via a positive locking.
  • the positive locking can basically already exist in the locking position of the locking assembly.
  • a variant is also included in which a positive locking to secure the locking assembly against removal from the third locking part only exists when a certain load acts on the locking device.
  • the securing mechanism has at least two securing parts which interact with one another in a form-fitting manner in the closed position of the locking collar in order to secure the locking assembly against removal from the third locking part.
  • These at least two securing parts can also engage with one another in a form-fitting manner as soon as the locking assembly reaches the closed position or, alternatively, can at least be brought into a relative position in which the form-fitting engagement of the two securing parts in one another is automatically achieved when a load is applied to the locking device.

  • a magnetic element can comprise a permanent magnet which is arranged at a corresponding location on the closure device.
  • the securing part In a securing position in which a securing part of the securing mechanism is positioned under the action of at least one magnetic element, the securing part can already be in positive engagement in order to secure the locking assembly against being adjusted into the release position. However, it can also be provided that the securing part is still in an intermediate position in its securing position, from which the securing part is only displaced into an engagement position under the action of additional load on the locking device, in which the blocking positive engagement then exists.
  • a variant embodiment further provides that the at least one securing part is adjusted into the securing position under the effect of the at least one magnetic element when the closure assembly is transferred into its closed position.

  • the locking assembly is thus folded about the pivot axis parallel to the first spatial direction, for example by approximately 180°.
  • a (resulting) magnetic force for holding the locking assembly in its locking position with respect to the third locking part then acts along a spatial axis that is parallel to a second spatial direction (y) running perpendicular to the first spatial direction.
