Description
Technical Field
The present invention relates to improvements in closure systems, particularly for the leather arts and textile industries, and more particularly to improvements in existing magnetic closure devices.
Background
With reference to US4,021,891 and US4,453,294, magnetic closure devices are known which make use of a first magnetizing assembly cooperating with a second assembly made of ferromagnetic material by means of a permanent magnet having a through hole on a ferromagnetic base provided with a protruding central ferromagnetic portion, the protruding portion being located at the center of the through hole of the magnet, the ferromagnetic base and the magnet being fastened to each other by a non-magnetic component, the second assembly having a protruding portion extending axially with respect to its base, the protruding portion being intended for the magnetic coupling of the two assemblies.
When they are perfectly axially aligned, magnetic engagement is achieved. However, with this type of closure, axial alignment of the two components must be performed by the user. In fact, the protruding ferromagnetic part of the second component is inevitably attracted towards the magnets located on the periphery of the central hole of the first component, instead of being attracted towards the central hole of the first component, which should be coupled.
Displacing the two assemblies one after the other to axially position the two assemblies and actuate the closure, results in damage and scratches on the surface of the appearance parts.
With reference to the US patent 3,141,216, another magnetic closure device is also known, which enables axial alignment and closure of the assembly without the aid of the user. This type of closure uses two assemblies, both of which are magnetized with two magnetic rings having axial magnetization, the rings being positioned with opposite poles facing each other when the two assemblies are facing each other. At the centre of each ring there is a projection which extends axially with respect to the base, is set back with respect to the magnetic ring on one component, and, conversely, projects on the other component. This operational constraint, where the two magnets overlap when the assembly is closed, has the major disadvantage of producing a thick and unsightly closure.
There are also hidden magnetic enclosures placed under the surface of an item or accessory or in a liner. These different types of closures have several major drawbacks:
since they are located below the material, they do not produce a magnetic coupling when inserted and therefore do not guarantee an optimal closure, in particular when sheared.
To obtain sufficient magnetic retention, stronger, larger magnets must be used, with the risk of damaging the electronic equipment, credit cards, etc.
Finally, with reference to patent EP 2,490,560, another type of magnetic closure device is known, in which the magnets of each assembly have facing identical poles, one of the two magnets having a through hole for receiving the circular magnet of the opposite assembly when the device is closed, each of the two magnets cooperating with the ferromagnetic part of the opposite assembly, i.e. at the periphery of the cylindrical magnet of the first assembly and at the centre of the magnetic ring of the second assembly.
Although this type of closure enables axial alignment of the automation components, it is still thick since one component cannot be fully inserted into the other, the insertion being only partial.
With this type of closure, the contact of the two components is comprehensive, resulting in premature and rapid wear of the visible part of the magnetic closure.
In fact, the strongest and most wear-resistant ferromagnetic parts do not touch each other. Each ferromagnetic part is in contact with a magnet of the counter-assembly, which is a very fragile component.
Disclosure of Invention
According to the invention, it is understood that a non-magnetic part can be placed to protect and cover the magnets, but that this non-magnetic part will result in the formation of an air gap between each magnet and the ferromagnetic part of the counter-assembly and thus reduce the closing magnetic force.
It is an object of the present invention to provide a magnetic closure device that concentrically interlocks component parts by utilizing self-centering and double insertion of a magnetic assembly.
Another object of the present invention is to enable an assembly to be inserted integrally into another assembly, thus obtaining a very delicate and aesthetically pleasing magnetic device.
Another object of the invention is to guarantee an optimal and consistent magnetic retention of the assembly while using magnets of small dimensions.
Another object of the invention is to obtain the connection of the assemblies via the central ferromagnetic portion of each assembly and avoid contact with the visible parts.
Another object of the invention is to be able to utilize the usual fastening means in the closure of the device.
To this end, according to the invention, there is provided a magnetic closure device by concentric interlocking of the components of two magnetic assemblies, each component of a magnetic assembly being interlocked around a same central axis, the components of a magnetic assembly being proportional and complementary to the components of the other magnetic assembly, each magnetic assembly comprising a permanent magnet having an axial magnetization, said magnets of each of the two assemblies being placed with facing identical poles, said magnetic closure device being intended to removably connect a first surface and a second surface, characterized in that:

-a second ferromagnetic portion in the form of a tubular rod having a thinner portion and a larger portion, said thinner portion being adapted to pass through the second central through hole of the second ferromagnetic base, the ends of said thinner portion being intended to be fitted and fastened to the fastening means of the second magnetic assembly, the other larger portion of the tubular rod forming a second protruding ferromagnetic central portion which covers the second central through hole and extends axially with respect to the surface of the second ferromagnetic base;
-a second permanent magnet with axial magnetization, having a height greater than the height of the second projecting central ferromagnetic portion and having a central through hole, the diameter of said second permanent magnet being smaller than the diameter of the through hole of the first permanent magnet of the first assembly, the diameter of the through hole of said second permanent magnet being greater than the peripheral dimensions of the first and second projecting ferromagnetic portions of the first and second magnetic assemblies, respectively, said second magnet being arranged on the surface of the second ferromagnetic base, extending axially on the periphery of the second projecting portion with respect to the surface of the second ferromagnetic base and projecting from said second projecting central ferromagnetic portion at its center; a first magnetic pole, which is the same as the first magnetic pole of the first permanent magnet of the first magnetic component and is contacted with the surface of the second ferromagnetic base, and the second magnetic pole is axially opposite;

Thanks to the invention, it is possible to insert entirely by the first magnetic assembly, by means of the second magnetic assembly, thus obtaining a closure with self-centering and very thin double insertion.

In the case of flush insertion of the two magnetic assemblies (F, M), the insertion height (H2) of the first magnetic assembly (F) is equal to the sum of the heights (H1, H3) of the two projections (2A, 7A) added to the height (H6) (fig. 14), the height (H6) being the height of the ferromagnetic base (6) and the height of the rear part (10C) of the container (10).
With reference to fig. 16, a magnetic closure device according to another embodiment is shown in a cross-sectional view in an open position, in which the cumulative height (H1, H3) of the two protruding central ferromagnetic portions (2A, 7A) is equal to the insertion height (H4) of the second magnetic assembly (M), providing a double connection of a double insertion accumulation for the magnetic closure device.
The heights (H1, H3) of the projections (2A, 7A) need not be the same.
Referring to fig. 17, a magnetic closure device according to the same embodiment as fig. 16 is shown in a cross-sectional view in a closed position.
The cumulative height (H1, H3) of the two projecting portions (2A, 7A) of the first (F) and second (M) magnetic assemblies is equal to the insertion height (H4) of the second magnetic assembly (M). When the two magnetic assemblies are connected, the upper portion (10B) of the second magnetic assembly (M) is in contact with the surface (1A) of the first ferromagnetic base (1) of the first magnetic assembly (F). In addition to the connection of the two protruding central ferromagnetic portions (2A, 7A) and the double insertion of the second component (M) into the first component (F) and of the first protruding central ferromagnetic portion (2A) into the second magnetic component (M), the second pole (9B) of the second magnet (9) of the second magnetic component (M) is located in the vicinity of the surface (1A) of said first ferromagnetic base (1), so as to generate in addition an additional magnetic attraction force.
With this embodiment, the insertion height (H4) of the first magnetic assembly (F) also remains customizable according to the desired insertion of the second magnetic assembly.
However, in the case where a flush insertion of the magnetic assembly is desired, the insertion height (H2) of the first magnetic assembly (F) is this time equal to the height (H5) of the second magnetic assembly (M) (fig. 14).
With reference to fig. 18, a magnetic closure device according to the invention and according to the same embodiment as fig. 13, 14 and 15 is shown in a sectional view, i.e. with the cumulative height of the protruding ferromagnetic portions (2A, 7A) greater than the insertion height (H4) of the second magnetic component (M) fastened on the article or accessory.
Each of the two magnetic assemblies (F, M) is fastened on a surface (15A, 15) distinct from the article or accessory, facing each other and intended to be approached by each other and removably approached and magnetically retained when the two magnetic assemblies (F, M) are closed.
The magnetic assembly (F, M) is fastened to a surface (15A, 15) of the article or accessory by fastening means 3, 8, respectively. The fastening devices are inserted through a surface (15A, 15) of an article or accessory and each cooperates with a ferromagnetic element (14A, 14), here represented in the form of a ferromagnetic counter-plate, placed below the surface of the article or accessory and adapted to receive a fastening device (3, 8) of a magnetic assembly (F, M).
The fastening device (3, 8) is horizontally folded after insertion of the ferromagnetic elements (14A, 14), so as to fasten the two magnetic assemblies (F, M) to the article or accessory
Thanks to the particular configuration of the magnetic closure device according to the invention, the first magnetic component (F) is adapted to cooperate magnetically with the ferromagnetic element (14), said ferromagnetic element (14) acting as a means of fastening the second magnetic component (M) in opposition, producing an additional magnetic retention of the component.
The ferromagnetic element (14) has an outer diameter greater than the diameter (D9) of the second magnetic assembly (M) (fig. 14) and advantageously has a diameter equal to the diameter (D4) of the first magnet (4) of the first magnetic assembly (F).
In order for the connection between the two magnetic assemblies (F, M) to comprise the connection between the magnet (4) of the first assembly (F) and the ferromagnetic element (14) when the device is closed, the insertion height (H2) (fig. 13) of the first magnetic assembly (F) is equal to the sum of the heights (H1, H3) (fig. 13, 14) of the two projecting central ferromagnetic portions (2A, 7A) and the height (H6) (fig. 14) of the ferromagnetic base (6) of the second magnetic assembly (M) and of the rear portion (10C) of the first container (10).
With reference to fig. 19, a magnetic closure device according to the invention in the closed position according to the same embodiment as in fig. 18 is shown in a sectional view.
Two surfaces (15, 15A) of the article or accessory are removably attached to each other by closing the closure means.
The second magnetic assembly (M) is inserted and magnetically connected to the first magnetic assembly (F) through the outer surfaces (7C, 2C) of the two protruding ferromagnetic portions (7A, 2A) of the second (M) and first (F) magnetic assemblies, respectively.
The insertion height (H2) (fig. 13) of the first magnetic assembly (F) enables the second magnetic assembly (M) to be inserted perfectly and flush when the magnetic device is closed, the upper part of the first container (5B) of the first magnetic assembly (F) contacting the opposite surface (15) of the article or accessory, the second pole (4B) of the first magnet (4) thus being located in the vicinity of the ferromagnetic element (14), a magnetic attraction being generated between the two elements, the first magnet (9) and the ferromagnetic element (14).
The surface of the non-magnetic container and the article or accessory passes the magnetic field of the magnet (9).
With reference to another embodiment, not shown, said ferromagnetic element (14) can also be placed on the surface (15) of the article or accessory, i.e. between the rear base (6B) of the second magnetic assembly (M) and the surface (15) of the article or accessory.
Herein, said ferromagnetic element (14) is not intended to fasten the second magnetic component (M) to an article or an accessory, but is adapted to cooperate with a fastening means (8) of said second magnetic component (M).
With reference to fig. 20, which shows, in a sectional view, another type of embodiment of the same magnetic closure device as in fig. 18 and 19 in the open position, with the difference that:
the ferromagnetic element (14) is replaced by a third permanent magnet (16) with axial magnetization having a first magnetic pole (16A) identical to the first magnetic poles (4A, 9A) of the first (4) and second (9) permanent magnets of the first (F) and second (M) magnetic assemblies, respectively, and a second magnetic pole (9B) identical to the second magnetic poles (4B, 9B) of the first (4) and second (9) permanent magnets of the first (F) and second (M) magnetic assemblies, respectively.
The third permanent magnet (16) is placed under the surface (15) of the article or accessory such that the first pole (16A) is adjacent, i.e. in contact with the surface (15) of the article or accessory, and the second pole (16B) is opposite.
Said third magnet (16) is adapted to cooperate with the fastening means (8) of the second magnetic assembly (M) to fix said second magnetic assembly to the article or accessory and has a diameter greater than the diameter (D9) of the second magnetic assembly (M) (fig. 14).
Advantageously, the diameter of the third permanent magnet (16) is equal to the diameter (D4) of the first permanent magnet (4) (fig. 13).
The insertion height (H2) (fig. 13) of the first magnetic assembly (F) is equal to the sum of the heights (H1, H3) (fig. 13, 14) of the two projecting central ferromagnetic portions (2A, 7A) and of the heights (H6) (fig. 14) of the ferromagnetic base (6) of the second magnetic assembly (M) and of the rear portion (10C) of the first container (10).
Thus, when closing the magnetic means, the second pole (4B) of the first magnet (4) of the first magnetic assembly (F) and the first pole (16A) of the third magnet (16) are brought close to each other, so that between the opposite poles (4B) (16A) of the first permanent magnet (4) and the third permanent magnet (16) of the first magnetic assembly (F), a magnetic attraction is generated on the entire non-magnetic surface of the article or accessory, creating an additional hold for the closing device according to the invention.
With regard to all the different embodiments mentioned above, and in particular with regard to the figures relating to the different embodiments, the magnetic poles are indicated as a non-limiting example, i.e. south "S" refers to the first magnetic pole of the magnet and north "N" refers to the second magnetic pole of the magnet.
The north pole may be placed as a first magnetic pole and the south pole may be placed as a second magnetic pole.
Similarly, as a non-limiting example, the container (5, 10) is fastened by crimping its side walls (5D, 10D) in such a way as to form a fold back (5C, 10C) on the rear base (1B, 6B) of the magnetic assembly.
It will be appreciated that the container may have any particular feature, in particular a small support column, to hold the different component parts of the magnetic assembly.
The magnetic closing means according to the invention are particularly intended to removably connect a first surface and a second surface of an article or an accessory.
In contrast to known magnetic closures, the person skilled in the art will understand that a magnetic closure allows self-centering of the assembly and combines a double insertion, in particular a monolithic insertion, of said assembly, thus proposing a very thin and aesthetic magnetic closure while ensuring optimal retention.
