FOOTWEAR ITEM COMPRISING A DEVICE WITH A TUBE FOR STORING INFORMATION OR AN OBJECT

The present invention relates to a footwear item with a device for storing information or an object and a method for producing a footwear item of this kind.

In accordance with a first aspect, the present invention relates to a footwear item including a device for storing information or an object. In accordance with a second aspect, the invention proposes a footwear item capable of receiving a storage device. In accordance with a third aspect, the invention proposes a casing comprising a device for storing information or an object suitable for insertion in a footwear item. In accordance with a fourth aspect, the invention proposes a method for producing a footwear item.

A “footwear item” shall be understood here to mean any style of footwear item (child's, women's, men's), of espadrille, of sandal, of boot, or bare feet.

According to the prior art, there exist footwear items with a housing for a storage module accessible from outside.

Publication WO-A1-9311681 describes a sports footwear item comprising a sole and a receptacle incorporated in the sole and intended to receive and releasably hold a plug-in module in a rail, the plug-in module including a battery and electrical circuit elements.

Publication US-A1-2007260421 describes another example of a footwear item in which a housing element is provided for an electronic module and is accessible from outside the structure of the footwear item, said footwear item also comprising a casing with a removable cover element.

These structures are generally formed by different devices that can be housed in the footwear item and that can be easily fixed to the sole.

However, one criticism of these known footwear items with storage device could be considered the fact that they are not designed to prevent dirt or water from deteriorating the casing, and that they are heavy, bulky and unreliable. For the storage structures, the assembly and disassembly of systems of this kind requires a lot of time. In addition, problems result also in respect of their implementation, because these devices for storing an object are unreliable and are not resistant to the weather, to frost, or to elevated temperatures. In particular, over time, these storage devices can easily detach from the footwear item (in the case of frost or elevated temperatures) or are no longer leak-tight.

Difficulties in respect of implementation manifest in particular for certain storage devices which are not securely fixed to the footwear item or which are not completely leak-tight, which poses certain problems.

In addition, these known devices for storing information or an object in footwear items are relatively easy to open, even for a child. Furthermore, access to the information or the object placed in the known storage devices is not facilitated.

It is therefore clear that there is a need for a system which, to a large extent, makes it possible to overcome the disadvantages encountered in the prior art. One object of the invention is to provide a footwear item comprising a device for storing information or an object.

The invention has a number of objectives:

• • assist individuals in danger or incapable of communicating crucial information at a specific moment (young children, handicapped individuals, individuals who have been involved in an accident resulting in memory loss, unidentified persons, etc.)
  • allow two adults to communicate items and information when the person wearing the footwear items is unable to assist them in this process (young children, handicapped individuals, etc.)
  • protect against potential attacks (deterrent)

The presence of the device for storing information or an object makes it possible to reinforce a feeling of safety for the individual wearing the footwear item.

It is possible to file/store in this device an important object or a paper document containing information (indispensable survival list, identification information), such as

name

date of birth

personal address

blood group

allergy to medicaments and foods

other medical information

contact name and person (family)

doctor's name

hospital information, etc.

other information: tattoos, glasses, specific identifying marks

It is also possible to file/store an important object in this device, such as medicaments, a microchip, a GPS tracker, money, a USB stick, etc.

The problem to be solved is that of overcoming the disadvantages of the prior art mentioned above and finding a footwear item that includes a device for storing information or an object, which device is fixedly connected to the footwear item and is completely leak-tight.

Consequently, one object of the present invention is to provide a footwear item including a discrete device for storing information or an object, which device also offers a high ease of use whilst being very reliable and robust.

Another object of the present invention is to propose a footwear item including a completely leak-tight and robust device for storing information or an object, which device is also easy to open for an adult, but relatively difficult to open for a child.

The present invention makes it possible to simplify the manipulation of the footwear item so as to facilitate the positioning of the device for storing information or an object and so as to easily and fixedly anchor said device in the footwear item whilst also making said device leak-tight and fixed permanently to the footwear item. Another objective of the invention is to facilitate access to the information or the object placed in the storage device.

This objective is achieved, in accordance with the invention, in that the footwear item with device for storing information or object has the features of the characterising part of claim 1.

To this end, in accordance with another aspect, the invention proposes a method for producing a footwear item with a device for storing information or an object which has the features of claim 24.

More particularly, to this end, in accordance with the invention, this goal is achieved by the fact that the footwear item with device for storing information or object comprises a sole including a front part and a rear part, wherein the sole has a hole that opens onto the front part or the rear part of the footwear item, the footwear item comprising a casing inserted into the hole in the sole, said casing comprising a duct suitable for insertion into the hole in the sole, the duct comprising an opening and being fixed in the hole in the sole in order to secure the duct to the sole permanently; and a cover hermetically sealing the opening in the duct such that the casing is leak-tight, the cover including a tube suitable for insertion into the duct via the opening and suitable for allowing the storage of information or an object.

This makes it possible to prevent dirt or water from deteriorating the casing, the cover closing the mouth of the hole in a leak-tight manner whilst said device is easy to open for an adult, but is relatively difficult to open for a child.

In addition, this makes it possible to achieve a robust and leak-tight fixing between the sole and the casing, the anchoring means being designed to make it possible to secure the duct to the sole permanently. The fixing of the cover on the duct results in the creation of a resistance which makes it difficult for a child to remove the cover. This closure system makes it possible to obtain a leak-tight fixing, which is easy to open for an adult, but relatively difficult to open for a child. In addition, this makes it possible to facilitate access to the information or the object placed in the tube of the storing device.

As shown in FIG. 11, if the duct (3) is elongate and octagonal (423) in cross section, the hole (2) in the sole (1) will also be of a corresponding octagonal cross section (422), as will also the cover (424) and the tube (425).

The duct (3) and also the cover (4) can be made on the basis of any sort of impermeable (metal, aluminium, stainless steel, any sort of plastic, carbon, rubber, etc.).

The duct (3) is preferably smooth on the inner face (143) so as to allow the tube incorporating the objects to be easily inserted and removed.

The duct (3) is fixed permanently in the sole (1) of the footwear item by anchoring means.

In accordance with a preferred embodiment of the invention shown in FIG. 12, the outer face of the duct comprises bumps (233) so as to form a means for anchoring the duct (3) in the hole (112, 212) of the sole (1) and so as to make it possible to fix the duct (3) to the sole (1) so as to secure them permanently. These bumps (233) of half-moon shape are open towards the opening of the duct (153) and solid towards the closed part of the duct (353). When the duct (3) is inserted into the hole (2), said duct slides easily as far as the bottom of the hole.

The bumps (233) then block the duct (3) in the hole (2) and prevent it from being removed, such that the duct (3) is permanently joined to the sole (2).

In accordance with the embodiment shown in FIG. 12, the hold of the duct (3) in the hole (2) of the sole (1) can be further reinforced advantageously by glue.

The duct (3) can be fixed, for example to the sole (1), by another adhesive fixing means, cement, soldering, or by other fusing techniques.

In accordance with another preferred embodiment of the invention shown in FIGS. 13 to 15, the outer face of the duct comprises barbs (fins) (333) so as to form a means for anchoring the duct (3) in the hole (112, 212) of the sole (1) and so as to make it possible to fix the duct (3) to the sole (1) so as to secure them permanently. These barbs (333) are suitable for preventing the duct (3) from being removed from the hole (2) after having been inserted thereinto.

As can be seen in FIG. 14, the inner wall (102) of the hole (2) in the sole can be smooth, and only the outer part of the duct (3) contains barbs (333).

As can be seen in FIG. 15, in accordance with another embodiment, the inner wall (202) of the hole (2) contains the same barbs (202), which cooperate with barbs (333) on the outer part of the duct (3) so as to anchor and fix the duct (3) to the sole (1) and so as to secure them permanently.

In accordance with the embodiment shown in FIGS. 14-16, the hold in the hole (2) of the sole (1) can be further reinforced advantageously by glue.

In accordance with another preferred embodiment of the invention shown in FIG. 16, the duct (3) comprises, at the end situated in the vicinity of the bottom of the hole (232), a flexible system formed of a plurality of elements of pointed shape (433), preferably four elements (433). As the duct is inserted into the hole (2), the pointed elements (433), which are flexible, can be depressed inwardly so as to facilitate the insertion thereof into the hole (2). By then inserting a cylinder (not shown) into the duct (3), during the manufacture of the footwear item, the various pointed elements (433) extend outwardly and are wedged in the sole (1) so as to remain blocked there and thus fix the duct (3) to the sole (1), these parts being secured permanently.

In accordance with the embodiment shown in FIG. 16, the hold in the hole (2) of the sole (1) can be further reinforced advantageously by glue.

The anchoring means of the duct (3) in the presented embodiments can be combined with one another.

In accordance with another preferred embodiment of the invention shown in FIG. 17, the duct is smooth (133) and is fixed in the hole (2) of the sole (1) thanks to the glue. The duct (3) and the sole (1) are secured permanently solely by glue.

Description and Fixing of the Cover to the Duct:

FIGS. 18 to 27 show the cover (4) hermetically closing the mouth of the duct (3) so as to allow robust fixing between the cover (4) and the duct (3) and so as to make the casing leak-tight.

The cover (4) preferably comprises a first fixing part, and the duct (3) comprises a second fixing part, the first and second fixing parts being arranged so as to cooperate together.

This makes it possible to obtain a robust and leak-tight fixing between the cover (4) and the duct (3).

In a preferred embodiment of the invention shown in FIG. 18, the cover (4) comprises flexible toric lamellae (114) on the outer face, suitable for cooperating with a duct (3), the inner face of said duct (3) being smooth (143).

The cover (4) comprises flexible toric lamellae (114) on the outer face. By inserting the cover (4) into the duct (3) until the opening of the duct (153) contacts the base of the cover (104), the lamellae (114) can be folded slightly, thus creating a resistance which makes removal of the cover (4) difficult for a child whilst ensuring the tightness of the casing.

In order to remove the cover (4), it is suffice for the person to pull strongly on it by means of a grip (414) situated on the base of the cover (104).

In a preferred embodiment of the invention shown in FIG. 21, the cover (4) is formed by a lever-based closing system (134), suitable for cooperating with a duct (3), the inner face of said duct being smooth (143).

This system (134) comprises a pin (1134) connected between a plate (2134), at the lower base (3134), and a lever (4134), at the head of the rod (5134). An O-ring (6134) made of rubber and a blocking piece (7134) in contact with the opening of the duct (153) are positioned between these two parts. When the closing system (134) is in contact with the opening of the duct (153) and therefore the body of the part (8134) is introduced into the duct (3), by pivoting the lever (4134) through 90 degrees relative to the duct 93), the pad (2134) approaches the blocking piece (7134) and thus compresses the rubber O-ring (6134). The diameter of said O-ring increases and thus tightly blocks the lever-based closing system (134) in the duct (3).

In a preferred embodiment of the invention, shown in FIGS. 19, 20 and 22, the cover (4) comprises a first screw thread on the outer face (214) and the duct (3) comprises a second screw thread on the inner face around the mouth (243) of the duct, so as to correspond to the first screw thread when the cover (4) closes the opening of the duct (153).

The first screw thread (214) screws into the second screw thread (243) when the cover (4) is screwed to the opening (243) and this screwing makes it possible to obtain a leak-tight fixing, which is easy to open for an adult but is relatively difficult to open for a child.

The cover (4) preferably comprises a means (164) for turning the cover (4) relative to the sole (1). This makes the screwing and unscrewing easier. The means (164) for turning the cover relative to the sole comprises a slot (164) intended for the insertion of a coin or a screwdriver.

In a preferred embodiment of the invention shown in FIG. 23, the fixing comprises a bayonet-based closing system (144). The end of the duct (3) contains grooves (443).

The cover comprises two lugs (1144). By coupling the duct (3) and the cover (4) woth bayonet-based closing system (144), the two lugs (1144) are in contact with the grooves (443). By pivoting the cover, the two lugs (1144) are blocked in the grooves (443) so as to allow robust fixing between the cover (4) and the duct (3) and for making the casing leak-tight.

The cover (4), in accordance with the embodiment shown in FIG. 23, preferably comprises a means for turning the cover (4) relative to the sole (1). This makes the screwing and unscrewing easier. The means for turning the cover relative to the sole comprises a slot intended for the insertion of a coin or a screwdriver (164).

In a preferred embodiment of the invention shown in FIGS. 24 and 25, the cover (4) comprises a rim (204) with a first screw thread on the inner face (314), and the duct (213) comprises a second screw thread disposed around the opening on the outer face (343), so as to correspond to the first screw thread when the cover (4) closes the opening of the duct (153), with the duct being slightly longer than the hole in the sole and protruding slightly beyond the outside of the sole (213).

This screwing makes it possible to obtain a robust and leak-tight fixing, which is easy to open for an adult, but relatively difficult to open for a child.

The cover (4), in accordance with the embodiment shown in FIG. 25, preferably comprises a means for turning the cover (4) relative to the sole (1). This makes the screwing and unscrewing easier. The means for turning the cover relative to the sole comprises a slot (164) intended for the insertion of a coin or a screwdriver.

In a preferred embodiment of the invention shown in FIGS. 26-28, the duct (3) is fully inserted into the sole (113). At the opening of the duct (153), the diameter of the hole (132) in the sole is slightly larger than the outer diameter (253) of the hole of the duct so as to accommodate the cover (4) during the screwing.

The cover (4) comprises a rim (204) with a first screw thread on the inner face of the cover (314), and the duct (113) comprises a second screw thread disposed around the mouth of the duct on the outer face (343), so as to correspond to the first screw thread when the cover closes the opening of the duct (153).

This screwing makes it possible to obtain a robust and leak-tight fixing, which is easy to open for an adult, but relatively difficult to open for a child.

The cover (4), in accordance with the embodiment shown in FIG. 27, preferably comprises a means (164) for turning the cover (4) relative to the sole (1). This makes the screwing and unscrewing easier. The means (164) for turning the cover relative to the sole comprises a slot intended for the insertion of a coin or a screwdriver.

The base of the cover (104) which contains the slot advantageously has a diameter of 3 mm larger than that of the body of the cover.

When the cover (4) is screwed to the duct (3), the base of the cover (104) is in contact with the sole (1) and thus prevents any dirt or liquid from penetrating between the sole (1) and the duct (3).

Technical Description of the Tube:

In accordance with the preferred embodiments of the invention shown in FIGS. 7, 18, 19 and 21 to 34, the tube (5) is of elongate form and is suitable for insertion into the duct (3) by being fixed on the base (104) of the cover (4).

The tube (5) is preferably inserted into the hole (2) so as to be removable. It is easier to insert documents or objects into the tube (5), and to remove documents or objects therefrom, when said tube is held in the hand.

So as to be able to insert and fix the tube (5) more easily into the hole (2) in the sole, this hole (2) is associated with a duct (3) that is preferably sealed on one side and open on the other.

In a preferred embodiment of the invention shown in FIGS. 29 to 34, the tube (5) inserted into the duct (3) can be fixed permanently (105) or removably (205) on the base of the cover (104). It can thus be inserted and removed manually from the duct (3) at the same time as the cover (4). The tube (5) and the base of the cover (104) can also be formed in one piece.

When the cover (4) is fixed on the duct (3), the tube (5) fills the inner part of the duct (3) from one end to the other. The duct (3) and the tube (5) preferably have a length between 1.0 and 10.0 cm, more preferably between 3.0 and 7.0 cm, even more preferably between 4.0 and 6.0 cm.

The tube (5) can be made of different materials, such as metal, aluminium, stainless steel, carbon, or a rigid plastics material. The tube (5) preferably can be made of a transparent material so as to be able to see the content thereof.

The tube (5) can be fixed removably (205) to the inner face of the cover (154) so as to be able to be detached if desired.

In a preferred embodiment of the invention shown in FIGS. 31 and 34, the removable fixing comprises a bayonet-type closing system, with bayonets (155, 255) situated on the inner face (215) or on the outer face (115) of the tube (5) depending on whether the groove openings (preferably approximately 0.5 mm tall) are oriented towards the outer face (354) of the cover or towards the inner face (254) of the cover, respectively.

For example, if the grooves (254) are open towards the inner face of the cover, one end of the tube comprises two flat lugs (255) situated outside the tube. By coupling the tube and the cover, the two flat lugs (255) are positioned between the grooves (254).

By pivoting the tube in one direction, the two lugs (255) are accommodated and blocked beneath the grooves (254).

As can be seen in FIG. 30, the tube (5) can be obstructed at its other end by a removable cap (135) so as to close and block the information or objects disposed in the tube (5). The head of this cap (1135) preferably has a diameter slightly larger than its body (2135) so as to be easily removed from the tube (5). This removable cap (135) is suitable for sealing the opening of the open tube (245).

In accordance with another preferred embodiment of the invention shown in FIG. 29, the tube with removable fixing (205) can also be closed by an end face (145) at the opening of the tube so as to obtain a closed tube (145).

The present invention is not in any way limited to the embodiment described by way of example and shown in the drawings. Numerous modifications of the details, shapes and dimensions could be made without departing from the scope of the invention. The present invention has been described with reference to specific embodiments which are purely illustrative and should not be considered limiting. The reference numbers in the claims do not limit the scope thereof.
