Abstract

The invention relates to a system for protecting the toes, which comprises a pair of shoes with certain adaptations so that a removable portable element with a casing can be fitted thereto and removed therefrom easily and quickly, by means of three lower tabs - two side tabs and one front tab - which fit to the sole of the shoe, and two straps - an inner strap and an outer strap - which fasten to the shoe, converting said street shoes into safety shoes and vice versa. The characteristics of both the shoe and the removable element mean that when the casing is fitted, it does not extend beyond the limits of the footprint, and therefore comfort is not compromised when the shoes are worn and the shoes remain aesthetic. The invention also has the flexibility of being able to have a wide range of standardised designs per model and size, which can then be interchanged with each other in order to increase the design options for the user. Said advantages cannot be found all at the same time in any of the current systems that exist today for the same purpose.

Description

CONVERTIBLE SHOE CONVENTIONAL TO SAFETY WITH

CAP

DESCRIPTION

OBJECT OF THE INVENTION

Currently there are people who, due to their activity, need to protect their toes to avoid or lessen some damage if any heavy object accidentally falls. The objective of the present invention is to offer a new portable solution, that is to say that by adding a removable element a pair of common shoes can be transformed with the adjustments that will be seen later, to safety shoes and vice versa and that offers several benefits that They are detailed below and cannot be found together in any of the devices that exist for this purpose today.

The current removable element systems by their characteristics are more suitable for occasional use, that is, in cases of visitors to the risk area that requires immediate protection and who do not have common safety shoes and wear any street shoe, in whose case was not considered important comfort or aesthetics but simply have a quick solution. The toe protection system of the present invention is focused on providing a portable solution but not for occasional use, since in addition to covering its primary protection function, it also focuses on covering the comfort and aesthetic characteristics and more still, it has the flexibility of being able to exchange the components of said shoe system - Removable element so that the user can increase their chances of wearing a pair of safety shoes of different designs.

BACKGROUND

Currently there are safety shoes that have a part commonly called a cap that can be made of steel, plastic or some other material and of different configurations and that is integrated into the shoe above the toes and protects them if by accident some heavy object will fall on them, reducing or avoiding the effect that this impact could have.

It has also been observed that most people find it uncomfortable to wear safety shoes both because they are stiffer and because they are heavier than any common street shoe and that for this reason they avoid using them as much as possible, Even many people choose to wear their safety shoes without putting them on so they can put them on when they arrive at the area where they are needed and in the same way change them for common shoes and without a cap when leaving that place.

In addition to the aforementioned safety shoes with a cap, there are two types of alternate devices that are used for the same purpose which can be placed on several types of footwear, one of them is called toe and which is basically a cap that has Some elements to be placed on the front of the shoe and the other is a rubber cover that covers all or part of the shoes that the user is already wearing, which has the cap integrated (Patent Spanish No. ES2230932 "Toe protection toe" and European Patent EP 2425731 "Safety Overshoe"). In the first case, as it can be used for any type of shoe that the user is already wearing and since these can be of a number of shapes and sizes, the mentioned toe has a very wide shape and size so that most of the shoes fit inside this and as a result it stands out from the shoe being larger than the usual footwear, in addition to being able to ensure it contains elements that go between the sole, the floor and the back of the shoe, making it uncomfortable and cumbersome when walking, in addition that can damage the shoe, fulfilling its function of protection, but without covering the part of comfort, or aesthetics. In the case of the option of cover for the shoe with integrated cap, it comes in sizes and should correspond to the size of the footwear on which it is intended to be used, but as it is wrapped in the shoe it becomes practically larger than the usual footwear, result difficult and uncomfortable when walking, as well as not covering with the aesthetic function and being able to damage the shoe. Since the current removable element devices do not have the comfort or aesthetic feature they are considered more suitable for temporary use and in case of any visitor to the area of risk that requires protection of the toes and that do not have Common safety shoes at that time, in which cases comfort and aesthetics have not been considered important but simply provide a quick protection solution to the toes.

Considering the above, a footwear system has been devised that is convertible, that is to say that it is a conventional shoe and that when required it can be placed a portable complementary part in a relatively easy and fast, turning it into a safety shoe and in the same way it can be removed when it is no longer needed. Said removable element is characterized by containing a bushing and being provided with the appropriate shape and design to fit properly, so that once installed and in position it is contained in the shoe, that is, it does not exceed its dimensions and shapes of the contour of the tread, making it feel like a common and current safety footwear and that when removing this part, it feels and looks like any conventional footwear, thus covering in addition to the foot protection function, the aesthetic and comfort part that Current systems do not have. It should be mentioned that the present invention also has the flexibility of being able to have a large number of designs for all tastes by changing materials, shapes, components, colors and textures, both of its removable element and footwear and being standardized by model and Size can be exchanged at will.

Therefore, this application is intended to protect the shoes named for the present invention, convertible shoes from conventional to safety with a cap and that is a system that has two components, a shoe with the necessary adjustments to contain its other piece called removable element, that is to say that it can be installed and removed depending on how it is required to use and that it has the previously exposed benefits that current devices for the same purpose do not have.

The pieces and characteristic details of these convertible shoes are clearly shown in the following description and in the accompanying drawings. BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF THE INVENTION

Convertible shoes from conventional to safety with a cap to which the present invention refers is a system comprising two components (1,2), the first is a part called removable element (1), which in turn is integrated an element called safety cap (3) and another called a removable element belt (26), the second one is the shoe (2) and it has the characteristics that will be described below in order to properly accommodate and contain the first component mentioned. This removable element (1) may be lined by the part exterior and interior, totally or partially of some coating material, such as fabric, leather, synthetic material or any other and even any combination of these and have any design, such as textures, color, printing or any combination of these This feature has been referred to as the outer part covering (32) for the visible part of the shoe once the removable element (1) is installed and the inner part covering (46) for its part that is not visible once the removable element is installed ( 1) and whose face goes in the direction of the shoe (2), this inner part coating (46) has the primary function of protecting the shoe from contact with the removable element (1) when installing and uninstalling it. In the same way, this removable element (1) may simply not have the outer part cover (32) or the inner part cover (46).

The removable element (1), is provided with three lower tabs (4, 5, 6) one on each side of the shoe, that is on its inner and outer side and which are called, inner lateral lower flange (4) and lower flange external side (5) and the third on the front, called the lower front tab (6). The inner lateral lower flange (4) and the outer lateral inferior flange (5) have a fold towards the inside of the shoe as shown in the details (15 and 16) respectively, which have been called the inner inferior lateral fold (15 ) and external lower lateral fold (16), these folds are housed in an internal lower lateral step (37) and external lower lateral step (38), which is presented in the lower part of the sole of the shoe (35) and runs along the contour of the sole as seen in figure 7 by the points that join the line (41,42 and 43), said fold also has contact with the outer side edge of the sole (18) and inner side edge of the sole (19). Similarly the Lower front flange (6) has a lower front fold (20) that is housed in the lower front step (21) of the sole, intended for this purpose, this fold also has contact with the front edge of the sole (22) as It is shown in fig. 4.

This removable element (1) also has a lower outer contour of the removable element which is represented by an external line that passes through the points (7,8, 9 and 10) and another internal dotted line that passes through the points (11 , 12, 13 and 14) and which is called the lower inner contour of the removable element, the area of this contour will have contact with the upper edge of the sole, as seen in points (23 and 24), which represent only one pair of points in the CC cut of figure 6, this contact can also be seen in fig.l (36), in which an imaginary cut of the bushing (33) of the removable element (1) has been represented, for a better display. The previously described fixings allow that the removable element (1), cannot move upwards, downwards, nor backwards, additionally the removable element (1), contains a hole (25), through which the element's belt passes removable (26) that is already assembled to the removable element (1) and that turns in the form of "U" through said hole (25), this is represented in figure 2 and in figure 8, said element belt Removable (26) contains a seam to the belt (27) to be able to join itself and is also provided with the female part of a snap (28), which will fasten to its counterpart of this, male part of the snap pressure (34), which is already attached to another belt, called the shoe belt (29), which is cooked in turn to the shoe (2), by means of a seam to the shoe (30). This fixation described by means of the belt assembly to the removable element (26) and the belt assembly to the shoe (29), has the function of preventing the movement of the removable element (1) in the forward direction of the shoe (2), this being the last fixation that makes the removable element (1) unable to move from its position when the present system is used in its safety shoe mode as can be seen in figures 1 and 2. In addition to the fixing system previously described, other methods can be used, which are described below but not limited to; instead of the snaps, the female part of the snap (28) and the male part of the snap (34), a hook-and-loop plush sailboat system, buckle system, two closures or zippers or even zippers can be used a single closure or zipper that passes from the inside to the outside of the shoe (2) or vice versa through the top of the removable element (44), could also be replaced by a single belt that contains an elastic element and is simply cooked removable element (1) in its internal part and external part of the shoe (2) and to be placed it must be pulled back using the elastic so that it is positioned on the back of the shoe (45) with some elastic tension ensure that this removable element (1) does not move towards the front of the shoe (2).

Additionally, in figure 2, the removable element (1) can be seen, which, being in its installed position, is above the instep of the shoe (31), illustrated in a dotted line, and can also be seen in fig. 4, 5 and 6, this removable element (1) contains the safety bushing (3) and is the one that will protect the toes. It should be mentioned that the safety bushing (3) as part of the removable element (1) in the previously shown figures has been considered to cover the entire removable element (1), however it can be changed in such a way that the protection part span from the minimum protection zone to the toes of according to the regulations of each entity until it covers the entire removable element (1), the first case is illustrated as an example in a dotted line called the cap boundary line (40), in addition to the removable part (1), it could have some hole or a series of holes in the area shown in fig. 1 identified as an area without a bushing (39) with the purpose of reducing weight or even as one of its aesthetic design configurations, this removable element (1) can also count on a number of shapes and designs to those shown here. , adapting completely or partially to the shape of the shoe as long as it fits and can adapt to the shoe (2) as described above. Even the removable element (1) can be made standardized by model and shoe size, being able to occupy a large number of removable element designs (1) for each shoe model (2) and vice versa.

It has also been considered that the material of both the removable part (1) and the safety bushing (3) can be any and can have any design, such as color, texture or combination thereof, the safety bushing (3) also You can present any configuration developed as long as the characteristics of the regulations in force in safety footwear for the corresponding entity are met.

Finally, it is stipulated that the removable element (1) may or may not have the safety cap (3), in the case of not containing it, the toe protection function would no longer be in force and the objective of the removable element (1) without safety cap (3) would be to have a system that allows to have several designs of footwear changing the removable element (1) standard for size and model to your pair of shoes (2) and vice versa.
