The present invention relates to a magnetic closure, particularly for bags, rucksacks, and the like. More particularly, the invention relates to a magnetic closure with a reduced number of components.

As is known, for bags, rucksacks and the like magnetic closures have been known for decades which comprise a male element that can be coupled to a first flap of a bag, for example, and a female element that can be coupled to a second flap of the bag, with at least one magnet arranged at the male element or at the female element and a ferromagnetic element at the other one of said male or female elements.

The coupling between the male element and the female element occurs following the mutual approach of the two flaps to which the male element and the female element are respectively coupled.

However, magnetic closures of the known type have some drawbacks, for example if one wishes to provide an extremely thin closure so that the two flaps essentially fit together.

The aim of the present invention is to provide a magnetic closure, particularly for bags, rucksacks and the like, in which the male element and the female element of the magnetic closure are provided by means of a reduced number of components.

Within this aim, an object of the present invention is to provide a magnetic closure, in which the coupling between the male element and the female element of the magnetic closure provides a magnetic closure of reduced thickness with respect to magnetic closures of the known type.

Another object of the present invention is to provide a magnetic closure in which the male element is prevented from rotating inside the female element.

Another object of the present invention is to provide a magnetic closure that is highly reliable, relatively simple to provide and at competitive costs.

This aim, as well as these and other objects which will become better apparent hereinafter, are achieved by a magnetic closure, particularly for bags, rucksacks and the like, comprising a male element adapted to accommodate a magnet or ferromagnetic element, and a female element, said male element being associable with a first flap of a bag, rucksack or the like, and said female element being associable with a second flap of said bag, rucksack or the like, said male element being associable in a seat formed in said female element, characterized in that said male element comprises an enclosure with a cavity for accommodating said magnet or ferromagnetic element, said enclosure being adapted to mate in a cavity of said female element.

Further characteristics and advantages of the invention will become better apparent from the description of preferred but not exclusive embodiments of the magnetic closure according to the present invention, illustrated by way of nonlimiting example in the accompanying drawings, wherein:

Figure 10 is a transverse sectional view of the magnetic closure of Figures 7, 8 and 9.

With reference to the figures, the magnetic closure according to the invention, designated generally by the reference numeral 1, comprises, in a first embodiment, shown in Figures 1 to 3, a male element 2 and a female element 3. The male element comprises an enclosure provided with a cavity 4 to accommodate a magnet 5. Likewise, the female element can have an enclosure with a cavity 6 that is adapted to accommodate a magnet 7 or a ferromagnetic element. It is of course possible to provide both the male element and the female element with magnets 5 and 7.

As an alternative, the female element can be itself a ferromagnetic element, provided with a cavity and adapted to couple with the magnet of the male element.

The male element is adapted to be applied to a first flap 8 of a bag, rucksack or the like, and the female element is adapted to be applied to a second flap 9 of a bag, rucksack or the like.

The male element 2 has the particularity that the seat 4 for accommodating the magnet or ferromagnetic element enters the female element 3 for coupling between the male element 2 and the female element 3.

The male element 2 is shaped so that the seat 4 for accommodating the magnets 5 or ferromagnetic element is such as to allow the accommodation of the magnet 5 or ferromagnetic element. It is therefore the magnet 5 or ferromagnetic element that passes through the first flap 8 and couples within the female element 3. The female element 3 is provided with a cavity 6 that is formed so as to accommodate the magnet 7 or ferromagnetic element so that it straddles the second flap 9.

If instead the female element is itself the ferromagnetic element, the cavity 6 is not present.

The female element 3 is provided with a cavity 10 for accommodating the male element, said cavity being arranged either flush with the second flap 9 or so as to slightly straddle the second flap 9.

In this manner, the coupling between the male element 2 and the female element 3 allows to have a distance between the flaps 8 and 9 that is extremely reduced and therefore a magnetic closure of reduced thickness.

Both the male element and the female element are constituted by a maximum number of two components.

A sealing ring 11 for the male element and a retention ring 12 for the female element, each constituted by an elastic locking ring which is fitted around the seat 4 of the male element, which protrudes from the first flap 8 and around the seat 6 of the female element that protrudes from the second flap 9, allow to fix and retain the male element and the female element to the first flap 8 and to the second flap 9, respectively, without requiring other fixing elements.

In the first embodiment, shown in Figures 1 to 3, the first flap 8 is such that the seat 4 of the male element 2 is in contact with the flap 8, with the seat 4 of the male element provided with a flange 15 which forms a right angle with the seat 4, so as to accommodate the flap 8.

In the second embodiment, shown in Figures 4 to 6, the flange 15 of the male element 2 is instead provided with a recess 16 which forms a step that accommodates the first flap 8.

In the third embodiment, instead, the flange 15 is provided with a profile that blends with a curvilinear portion with the seat 4 of the male element and consequently accommodates the first flap 8. In this third embodiment, the male element has the outer lower surface provided with at least two protruding portions 20 and 21 which engage in corresponding seats 22 and 23 of the female element 3 so as to prevent a rotation of the male element within the female element when the two elements are mutually coupled.

Both the male element and the female element are provided monolithically as regards the cavity and the corresponding flanges that allow coupling with the flap 8 and the flap 9.

In practice it has been found that the magnetic closure according to the invention achieves fully the intended aim and objects, since can be provided with the male element monolithically as regards the cavity for accommodating the magnet or ferromagnetic element, with retention of the male element by means of an elastic retention ring and, likewise, the female element is provided, as regards the cavity for accommodating the magnet or ferromagnetic element, also monolithically and is retained by means of an elastic ring used in a similar manner for the male element.

The reduced number of components of the magnetic closure is combined with a reduced thickness of said magnetic closure.

The magnetic closure thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

All the details may further be replaced with other technically equivalent elements.

In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to the requirements and the state of the art.
