ACCESSORY FOR FOOTWEAR WITH LACES SUITABLE FOR PREVENTING THE UNFASTENING OF THE LACES.
Technical Field v The invention relates to the technical sector for the production of footwear accessories.
Background Art
The majority of footwear on the market is fastened with laces of various kinds. The fastening of footwear by means of laces has for some time been preferred by sportspeople, but presents the problem of having to be held in position during the movement of the foot. The problem of the unfastening of the lace knot is particularly troublesome above all during competitions.
Similar problems are presented by some work footwear, children's footwear or generally those with slightly rigid or smooth laces.
The problem is such that numerous attempts have been to resolve it, but among these the only valid solution until now is that of the double knot.
However, even this solution does not fulfil the necessary functionality nor the characteristics with respect to practicality, cost or limited encumbrance on the shoe, so much so that, in fact, is it standard practice to double knot the laces to prevent them from unfastening, a system that is not always effective or comfortable.
The main limitations of the solutions proposed until now are related to the lack of simplicity with respect to application and usage, given that each time the shoe is removed the lace holding device must be removed or moved from its position. \
The solution proposed reconciles the multiple requirements disclosed above. The invention in question only interferes minimally with the shoe, it does not create problems for the foot, it provides very simple usage, it remains
connected to the shoe when the latter is unlaced or removed and furthermore lends itself to the possibility of aesthetic personalisation, in order to be an accessory with little visual impact on the shoe or vice-versa a decoration and/or an instrument for advertising.
Disclosure of the Invention
The invention consists of a strip of tongue-shaped material, preferably in moulded rubber, having a connecting device (5) in the central area. With respect to the central connecting device, the two opposite parts (8) (7) of the strip are made in such a way that both can be folded towards the centre and can be joined to said device. One of the 1;wo parts has pebbling (10) on one face.
The strip has a suitable form and dimensions to be arranged between the tongue and the laces, the latter already being inserted into the suitable eyelets of the shoe and laced up according to the preferred method.
The positioning can be made with the shoe lasted or not.
The part having the pebbling must be placed by the side of the pin and turned upwards.
The part of the invention turned towards the toe of the foot, must be refolded around one or more of the lace crossings, preferably around the third, and joined to the central connecting device. This operation allows the invention to be held in connection to the shoe also when it is not completely fastened and each time that it is removed. The invention is in this way mounted on the shoe in the "opened" state.
Once the shoe has been fastened completely, namely after having tightened the crossings and knotted the laces in the usual way, in order to use the lace holding function of the invention, the part of the strip directed towards the pin must be folded around the knot or bow and it must also be joined to the central connecting device. The laces, through the part engaged in the knot
and in the bow, remain in this way confined on the interior of the invention, that blocks them and prevents the knot from unfastening. This effect is favoured by the pebbling that comes into contact with the laces. In this way the invention is mounted on the shoe in the "closed" state.
The invention does not present any part that comes into contact with the foot.
The limited encumbrance of the device, together with the possible flexibility and softness characteristics of the chosen material do not compromise the elasticity of the shoe. Its particular shape, its lightness and the strength of the rubber used, allow complete adaptability to the movements of the foot without producing any discomfort.
The device can be made in plastic, rubber, leather, leather textured paper or cloth or with assemblies of two or more of said materials.
With particular reference to Figure 5, a possible practical embodiment of the invention is shown as an example.
The footwear accessory (1) is made in rubber, with a mixture so as to confer on the system the extensibility and rigidity comparable with that of the shoe to which it is applied.
The accessory (1) consists of an elongated body (2) having in its central part, preferably not centred with regards to the two ends, a connecting device (4). Said connecting device is made by means of a mushroom-shaped peg including a head (5) and a shank (6). The shank (6) of the connecting device (4) rests on the elongated body (2) and is integral with it.
The elongated body (2) includes two areas (3) sufficiently flexible to allow the folding of the body itself. The two flexible areas (3) are found on opposite sides with respect to the central connecting device (4).
Two slots (7) and (8) are obtained on the two ends of the elongated body with such dimensions that they can be inserted onto the mushroom-shaped connecting device (4), in the sense that the head (5) can pass through each slot (7 and 8).
The shank (6) of the mushroom-shaped device (4) has a height (H) superior or equal to the total thickness (S1) and (S2) of the elongated body (2), measured in correspondence with the slots (7) and (8).
The shank (6) of the mushroom-shaped device (4) furthermore has a section (9) with an area equal to or lower than that of slots (7) and (8). i
The perimeter of the slot (8) furthest from the peg (4) is, taking into account the elasticity of the material, as a whole lower than the perimeter of the head (5) of the peg (4), in such a way that the head (5) can only pass through the slot (7) by means of a voluntary action.
On part of the surface of the elongated body (2) comprised between the mushroom-shaped device (4) and the slot (7), pebbling (10) is present that has the function of increasing the friction of this part of the surface of the elongated body (2).
The surface (11), placed on the side of the elongated body (2) opposite to that which has the mushroom-shaped peg (4), is coloured and personalized. With particular reference to Figures 1 to .4, one possible application of the invention to a sport shoe is shown as an example.
The accessory (1) is placed on the shoe (30) between the tongue (31) and the laces (32), the mushroom-shaped device (4) projects in correspondence with the third crossing of the laces. The longer side of the elongated body (2) is turned towards the pin with the pebbling turned upwards.
The part turned towards the toe of the foot is refolded (20) around the third crossing and the head (5) of the mushroom-shaped device (4) is forced to pass through the slot (8).
Once the shoe has been fastened (Figure 3) with the knot and the bow (33) over the accessory (1), the part of the elongated body (2) turned towards the pin is refolded around it (21) and the liead (5) of the mushroom-shaped device (4) is forced through the slot (7).
The laces, by means of the part engaged in the knot and in the bow, remain confined on the interior of the invention (22).
Only the lower surface (11) of the accessory (1) remains in view.

A first end, provided with the joining element (8) to the central connecting device, is folded over itself, connecting to said device and remaining steadily blocked in position, containing on its interior at least part of the laces of the shoe not engaged in the knot, thus allowing the locking of the accessory to the laces.
The second end, provided with a joining element (7) to the central connecting device, is folded over itself after which the laces are fastened, including on its
interior said fastening prior to folding, in order then to be joined to the central connecting device (4).
The folding of the first end that allows the locking of the accessory to the laces can be turned downwards or upwards, the attachment of said end to the central connecting device is movable and the connection is removed each time the shoe must be unlaced, or vice-versa when it is restored after the shoe has been fastened.
In the area (3) in which at least one end is folded, workings are provided that facilitate the folding operation.
