Description

Title of the invention: Modular shoe

[0001] The invention relates to a modular shoe having several possible uses. Previous Art

[0002] There are different types of modular shoes in the state of the art which most often make it possible to meet two different needs of the user during the day.

[0003] In particular, there are documents which aim to solve the following technical problem: making shoes whose rear part in contact with the heel can be opened to ventilate the interior which sometimes becomes damp during a long outing.

[0004] For example, the shoe described in JP 2005296327 has a rear heel portion that can be engaged or disengaged in a shoe body.

[0005] In the case of walking, the rear heel portion is fixed on the rear of the shoe body, and the shoe is used as a conventional shoe.

[0006] When the walker wishes to air his feet, the counter can easily be pivoted and attached to the upper part of the shoe, and the shoe then allows clearance of the heel.

[0007] In this situation, the counter attaches at the instep to the upper part of the shoe body, allowing the shoe to be held securely during use, and preventing its loss without requiring a separate counter storage accessory such as a bag.

[0008] This modular shoe, although practical, has a limitation: it is only the counter that pivots, not allowing, for example, ventilation of the lateral parts of the foot.

[0009] Furthermore, it is limited to two different uses.

[0010] Finally, only one sports shoe is described in this document JP 2005296327.

[0011] It is appropriate to propose a modular shoe for all types of shoes such as sneakers, tennis shoes, city shoes, moccasins, and which would give more possibilities of uses.

[0012] It is the object of the present invention to propose a modular shoe which makes it possible to respond to many more different situations. Description of the invention

[0013] The objective of the present invention is to provide a practical shoe, easy to put on and take off, having an aesthetic appeal while maintaining great comfort.

[0014] It allows three uses to be provided to customers in a single product.

[0015] The three possible uses are as follows: a first use “standard shoe”; a second use “mule” with complete relief of the heel; a third use “mule with adjustable strap” which allows the ankle to be held by an adjustable strap after having transformed the shoe into a mule.

[0016] For example, according to the invention, when the modular shoe is a city shoe such as a moccasin or a Richelieu shoe, Derby etc., it can be worn as a city shoe during the day and transformed into a mule in the evening to lighten the feet, the walk and allow the feet to breathe.

[0017] For example, according to the invention, when the modular shoe is a sports or casual shoe such as a tennis shoe, sneakers, a mountain shoe, it can adapt to different walking styles during the day and go for example from the city to the beach or from the city to the mountains, or from the mountains to the beach.

[0018] The modular shoe according to the invention can adapt to weather conditions, whether rain or sun.

[0019] In addition, the modular shoe according to the invention can be put on quickly and partially in order to save time, for example when taking out the trash or getting the mail, without crushing the counter.

[0020] The present invention relates more specifically to a modular shoe having a wear sole, a front half attached to the wear sole and covering the front of the foot, and a rear half pivoting relative to the front half, the front half comprising: a front part and a tongue, the pivoting rear half comprising two elements pivoting relative to the front half: a rear part which allows rear support of the foot and which surrounds the rear of the foot, and an adjustable strap allowing rear support of the ankle by tightening and which is located outside the rear part.

[0062] The present description describes, for illustrative and non-limiting purposes, a first embodiment with two pivoting fins as the rear part and a second embodiment with a single piece as the rear part, and several types of means for fixing these rear parts as well as several types of means for guiding and holding these rear parts.

[0063] It goes without saying that these types of means for fixing these rear parts as well as these types of means for guiding and holding these rear parts described with the first embodiment can quite easily be applied to the second embodiment and vice versa.

[0064] Furthermore, it goes without saying that other types of means for fixing these rear parts, as well as other types of means for guiding and holding these rear parts could be envisaged and that this description is not intended to be exhaustive but simply illustrative of the modular shoe according to the invention. Detailed description of the invention

[0065] The present invention relates to a modular shoe 1 having a wear sole 2, a front half 3 covering the front part of the foot (in particular the instep, the metatarsus, the toes) and fixed to the wear sole 2, and a rear half surrounding the back of the foot and in particular the ankle and the heel.

[0066] The rear half pivots relative to the front half 3 at a zone 4 called the middle zone of the shoe.

[0067] The outsole 2 is of length equal to or greater than the sum of the length of the front half 3 and the length of the rear half.

[0068] The length of the front half 3 is equal to or greater than that of the rear half.

[0069] A comfort sole can be simply superimposed on the outsole 2 without fit together and is not shown in the figures, for simplification. There may be one on all types of shoes, whether they are shoes with high outer soles, or with classic outer soles that are not high.

[0070] The invention is suitable for any type of shoe given all the production possibilities it offers.

[0071] It can be adapted to city shoes such as loafers, classic shoes like Richelieu shoes, Derby shoes etc...

[0072] It can be adapted to sports, casual or other shoes such as tennis shoes, golf shoes, bowling shoes, sneakers, mountain shoes etc.

[0073] It can be a high, normal, low shoe, with or without openings, etc.

[0074] Front and rear halves

[0075] The front half 3 comprises: a front part 3A including the vamp and the toe, and a central part 3B, such as a shoe tongue.

[0076] This front half 3 is little modified in the invention which essentially modifies the pivoting rear half and adapts the front half 3 to these modifications.

[0077] The rear half comprises two elements pivoting relative to the front half 3, around two axes of rotation 7 located at the level of the median zone 4: a rear part 5 which allows the rear of the foot to be held, and an adjustable strap 6 which allows the rear of the ankle to be held by tightening and which is located outside the rear part 5.

[0078] The rear part 5 forms the counter and the two left and right quarters (or two left and right quarter wings) of the shoe.

[0079] Thus, in certain embodiments, the invention can avoid having to produce all these parts separately (in particular the counter, the two quarters and the two quarter wings) and then assemble them, as is the case for many current shoes.

[0080] In other words, in these embodiments, the rear part 5 is the equivalent of the buttress, the two quarters and the two quarter wings.

[0081] In other embodiments, on the contrary, the rear half is made up of the sewn assembly, or other, of all these pieces made separately from each other.

[0082] Furthermore, the rear part 5 and / or the adjustable strap 6 are either permanently fixed to the modular shoe 1, or can be detachable from the modular shoe 1 and therefore can be removed if the user wants to use the modular shoe 1 only with the front half 3 and the outsole 2 in “mule” mode without the rear part 5 and / or without the adjustable strap 6.

[0083] The rear part 5 may have the same height as that of the front part 3A, and has its two front end edges in contact with the latter.

[0084] The rear part 5 and the adjustable strap 6 each pivot from a low position for holding the foot to a high position above the central part 3B or resting on the central part 3B, around two axes of rotation 7 placed on either side of the central part 3B on the front half 3 and / or on the outsole 2 of the shoe so as to allow the modular shoe 1 to have three different uses, as described in figures 1A to 1C which illustrate the kinematics of the modular shoe 1 according to the invention.

[0085] A first “standard shoe” use is carried out when the rear part 5 and the adjustable strap 6 are in the low position, the rear part 5 being in support or contact by its lower end edge on the outsole 2, as illustrated in [Fig. 1A],

[0086] In other words, the front half 3 and the rear part 5 by a lower end edge are supported on the outsole 2.

[0087] Indeed, the rear part 5 enters by its lower end over a certain height and along its entire circumference into the interior volume V of the shoe, the volume V being defined as a part of the volume which receives the rear of the foot when the user puts on the shoe.

[0088] The strap 6 remains outside the shoe.

[0089] A second “mule” use with heel relief is achieved when the rear part 5 and the adjustable strap 6 are in the high position above or resting on top of the front half 3, in particular the central part 3B, as illustrated in [Fig.IB],

[0090] A third use “mule with adjustable strap” with ankle support, is carried out when the adjustable strap 6 is in the low position and supported by tightening on the ankle and the rear part 5 is in the high position above or supported on the top of the front half 3, in particular of the central part 3B as illustrated in [Fig.lC],

[0091] Rear part

[0092] The rear part 5 may have a means 8 for securing the adjustable strap 6 which encircles or surrounds the entire rear part 5 between the two axes of rotation 7, as illustrated in FIGS. 2A to 4B.

[0093] The securing means 8 may comprise one or more loops for the adjustable strap 6, which makes it possible to guide the latter relative to the rear part 5.

[0094] The rear part 5 may have a strip of material 9 which allows it to be held by friction inside the outsole 2 along the inner periphery of the latter.

[0095] For example, it could be a rubber grip (a rubber strip on the lower edge of what could correspond to the wings of quarters and counter). The material is rubber for better contact with the sole of the shoe and to achieve optimal friction.

[0096] In a first embodiment of the rear part 5, the rear part 5 is formed from a single piece 5A which pivots around two axes of rotation 7, as illustrated in Figures 4A to 4B, and in Figures 1A to 1C which illustrate the kinematics of the modular shoe 1 without detailing the rear part 5.

[0097] In a second embodiment, the rear part 5 is formed of two fins 5B rigid ones which each pivot about an axis of rotation, and which are fixed to each other in a removable manner, as illustrated in Figures 2A to 3D and in Figures 1A to 1C.

[0098] The rigid fins 5B can be fixed to each other in a removable manner by any means such as a self-gripping adhesive strip 10 and / or by press studs 11.

[0099] They can therefore pivot together or independently of each other.

[0100] Thus, for example, thanks to this embodiment of the two fins 5B, it is possible to maintain one's foot in the modular shoe 1, while pivoting each of the fins 5B on either side of the foot around the two axes of rotation 7, the adjustable strap 6 being removed from the securing means 8 so as not to hinder the independent rotation of the fins around the foot, while being able to pivot around an axis of rotation 7.

[0101] Doubling the attachment between the two rigid fins 5B makes it possible to avoid release of the two fins 5B and to allow attachment to the outsole 2 of quality by these double attachment means of the two fins 5B.

[0102] Adjustable strap

[0103] In a first embodiment, the strap can be continuously adjustable to achieve continuous tightening, as illustrated in [Fig.4A].

[0104] In other words, it has a perfectly adjustable tightening so that the rear part 5 of the modular shoe 1 according to the invention can properly fit the shape of the rear part of the foot.

[0105] For example, the adjustable strap 6 is tightened using a self-gripping adhesive strip 12, which passes through a loop 12A to allow the rear part 5A to be tightened as desired depending on the dimensions of the user's foot and to ensure adequate support of the foot in the modular shoe 1.

[0106] In a second embodiment, the adjustable strap 6 is tightened using a tightening means with a so-called punctual or discontinuous adjustment with one or more notches 13B, as illustrated in FIGS. 2A to 3D.

[0107] For example, the adjustable strap 6 passes through a buckle 13C and is tightened with a notch 13B and perforations 13A.

[0108] The adjustable strap 6 can, for example, be seen as a belt in this second embodiment.

[0109] It may have a first pivoting part around a first axis of rotation 7, for example a strip, which will be partially folded back on itself to ensure the desired tightening.

[0110] Indeed, on the second axis of rotation 7, there may be another part independent of the first part such as a loop 13C with a notch 13B in which the band will pass to allow it to fold back on itself and exert its tightening, the notch 13B entering and cooperating with a perforation 13A of the strip to fix the tightening length of the adjustable strap 6. [YES] Positioning of rotation axes

[0112] Advantageously, as already described, the invention has two axes of rotation 7 or pivots.

[0113] The two axes of rotation 7 are located on the front part 3A of the front half 3 and / or on the outsole 2, in the zone 4 called the middle zone of the shoe.

[0114] The two axes of rotation 7 may be located symmetrically with respect to each other on the front part 3A and / or the outsole 2 of the modular shoe 1.

[0115] Advantageously, the axes of rotation 7 are the same for the rear part 5 and for the adjustable strap 6, which simplifies the manufacture of the shoe and makes it easier to switch from “standard shoe” use to “mule” use by a single rotation of the rear part 5 and the strap 6 capable of being secured to the rear part 5.

[0116] In a first embodiment of the invention, the rotation axes 7 are positioned on the outsole 2 and / or the front part 3A, and the length L of the rear part 5 is dimensioned relative to the height h of the central part 3B, so that the rear part 5 and the strap 6 are above the central part 3B in the high position after their rotation.

[0117] In this case, tightening the adjustable strap 6 when the strap 6 and the rear part 5 are above the central part 3B in the second “mule” use makes it possible to move the rear part 5 to bring it into upper support on the central part 3B so that the rear part 5 matches the shape of the central part 3B. The strap may or may not be in the securing means 8 of the rear part 5.

[0118] Continuous tightening is particularly suitable for this embodiment, because it allows the rear part 5 to fit the central part 3B and the front part 3A, the mechanical stress exerted by the strap 6 on the rear part 5 allowing the rear part 5 to move and deform in an adjusted manner when pressing on the central part 3B.

[0119] Thus, the rear part 5 does not hinder the user of the modular shoe 1 when walking.

[0120] In a second embodiment of the invention, the rotation axes 7 are positioned on the outsole 2 and / or the front part 3A, the length L of the rear part 5 is dimensioned relative to the height h of the central part 3B so that the rear part 5 is in upper support on the central part 3B and takes the shape of the central part 3B directly after its rotation in the second use “mule” and in the third use “mule with adjustable strap”.

[0121] Thus, the rear part 5 does not hinder the user of the modular shoe 1 when walking in these uses.

[0122] The length L of the rear part 5 which is the distance between an axis of rotation 7 and the rear end of the rear part 5 can be equal, for example, to the height h of the central part 3B, these dimensions being represented in [Fig.lA].

[0123] In a third embodiment not shown, the modular shoe may have attachment means, located on the front part 3A or on the central part 3B, of the rear part and / or of the strap 6 in the high position, so as to avoid discomfort for the user when walking in the second use “mule” and in the third use “mule with adjustable strap”.

[0124] Means of attachment to the outsole

[0125] The modular shoe 1 may have different types of means for fixing the rear part 5 to the outsole 2.

[0126] For example, by way of illustration but not limitation, a first type of fixing means may have a rod 14 housed in (or on) the rear part 5, and an end part 14A projecting from the rod 14 intended to enter / exit after rotation in a housing or recess 15 of the outsole 2, to lock / unlock the fixing of the rear part 5 in the outsole 2, as illustrated in FIGS. 2A to 3A.

[0127] More precisely, the rod 14 is arranged on a first fin 5B, for example on a female self-gripping element 10, and its end portion 14A passes through an opening 14B located opposite in the second fin 5B, for example on a male self-gripping element 10, to be housed in the recess 15.

[0128] The recess 15 may be located inside the “rear heel” of the outsole 2.

[0129] Thus, these elements make it possible to fix the single element 5A of the rear part 5 or the two fins 5B of the rear part 5 already attached to each other for example by the self-adhesive strip 10 and / or the press studs 11, to the outsole 2.

[0130] It is possible to put a metal part at the level of the opening 14B on the second wing of quarter 5B.

[0131] In other words, the fixing means can be considered as being a so-called key system, located on the buttress of the rear part 5, and which cooperates with the outsole 2.

[0132] This key system can be considered as a system for locking the end 14A of the rod 14 or bit using a lock or recess 15 located on the rear of the outsole 2.

[0133] When the bit is locked or fitted into the recess 15, the parts: outsole 2 and the two quarter wings 5B or the single part 5A will be locked to the outsole 2 and held together.

[0134] The rod 14 of the key may have, for example, steel wires sheathed in material plastic, for example polyvinyl chloride, which does not deform with a metal material type bit.

[0135] For example, by way of illustration but not limitation, a second type of vertical fixing means may have a strap 16 fixed to an external wall of the rear part 5, as shown in FIGS. 3C and 3D.

[0136] This strap 16 can pass into a non-through housing 17 to be wound around a rod 18 or hook, fixed in or on a rear part 5 of the outsole 2, for example in the heel of the outsole 2, as shown in Figures 3C and 3D.

[0137] The strap 16 may have male and female attachment or fixing means, for example a self-adhesive strip, arranged to face each other and attach once a length such that half of the strap 16 is slid around the rod 18 or hook, turned and folded back on itself.

[0138] The user can adjust the length of the strap 16 which is folded when closing the attachment or fixing means, as desired.

[0139] In another embodiment, it is also possible to arrange this rod 18 outside the outsole 2 on the rear outer wall of the heel and to slide, turn and fold the strap 16 around this rod 18, to arrange the male and female fixing means of the strap 16 opposite each other.

[0140] In another embodiment, it is obviously possible to make a through hole in the outsole 2 to allow the strap 16 to pass towards the outside of the shoe through the through hole so as to fold the strap back on itself after passing through the through hole of one half of the strap, which avoids the use of a rod or hook.

[0141] In a third type of attachment of the rear part 5A to the outsole 2, illustrated in [Fig.4A], a quarter-turn attachment system 22 is provided.

[0142] In a fourth type of attachment of the rear part 5A to the outsole 2, illustrated in [Fig.4A], the attachment means have a hook 23 attached to a lower end of the rear part 5A and cooperating with a rod 24 located in a recess in the heel of the outsole.

[0143] Means for guiding and holding the rear part

[0144] The modular shoe 1 may have means for guiding and holding the rear part 5, when the latter is tilted from front to back when the user wishes to switch from “mule” use to “standard shoe” use.

[0145] These guiding and holding means are located on the outsole 2 and complement the fixing means previously described to ensure good holding of the rear part 5 to the outsole 2.

[0146] They may include a groove 19 or cavity illustrated in [Fig.3B].

[0147] This groove 19 is located in the outsole 2 between an upper part 19A possible of outsole 2 and a 19B base of outsole 2.

[0148] This groove 19 allows the fins 5B or the single part 5A which can constitute the rear part 5 to be held in place, by clamping or friction.

[0149] Its thickness and height are configured to hold the rear part 5 straight in “standard shoe” use.

[0150] Its thickness may correspond substantially to the thickness of the rear part 5.

[0151] This groove 19 can be made on all types of shoes.

[0152] It helps to preserve the waterproofness of the shoes.

[0153] These guiding and holding means may also have other elements for guiding and holding the rear part 5, on the outsole 2 and intended to cooperate with slots 21 located in the rear part 5.
