Abstract
Description
Title of the invention: Shoe upper, its manufacturing method and shoe incorporating such an upper
[0001] The present invention relates to a shoe upper, its manufacturing method and shoe incorporating such an upper.
[0002] It relates in particular to a shoe upper comprising at least one front part, a rear part called a counter, and two quarters arranged opposite each other and each extending from the front part towards the rear part, each quarter being coupled by a connection to the rear part, the connection comprising at least one seam, the rear part of the upper comprising, at least locally, from the outside towards the inside of the upper, a facing and a so-called inner lining assembled to said facing and covering at least partially the inside of said facing.
[0003] It should be noted that the inside of the upper obviously corresponds to the part of the upper capable of coming into contact with the foot when the shoe is worn.
[0004] A shoe upper of the aforementioned type is known. Users' requests are to be able to have their shoes repaired more easily and to be able to personalize their shoes. At the same time, shoe manufacturers are looking for technical solutions to facilitate the reconditioning of shoes, in particular to limit raw material costs.
[0005] An object of the invention is to provide a shoe upper whose design makes it possible to satisfy the requirements of both the user and the manufacturer.
[0006] For this purpose, the invention relates to a shoe upper comprising at least one front part, a rear part called a counter, and two quarters arranged opposite each other and each extending from the front part towards the rear part, each quarter being coupled by a connection to the rear part, the connection comprising at least one seam, the rear part of the upper comprising, at least locally, from the outside towards the inside of the upper, a facing and a lining called an inner lining assembled to said facing and at least partially covering said facing, characterized in that for each quarter,the lining of the rear part extends in projection from the facing of the rear part and from the connection of the rear part to said quarter and comes to partially cover from the outside of said quarter to form a thermal screen for at least partial protection of said quarter and / or a guide to aid in the disassembly of the rear part.
[0007] The connection of the rear part to a quarter is at least one connection of the lining of the rear part to said quarter, this connection being able to further associate the lining of the rear part to the facing of the rear part.. The design of the rear part of the shoe and its connection to the quarters allows easy disassembly of the rear part of the shoe which constitutes a wear or customization part. The fact that a part of the lining which extends in projection from the facing of the rear part comes to cover each quarter allows to protect each quarter during dismantling in particular when a flow of hot air is used to assist in this dismantling. Furthermore, access to the lining of the rear part due to the design of the connection between the rear part and each quarter allows easy separation of the rear part of the quarters, the connection being used as a guide to assist in the separation. Thus, the quarters can be reused for the manufacture of a new upper whose rear part may or may not be aesthetically identical to the one previously removed.A new upper can thus be designed at a reduced cost. The fact that the lining extends beyond the facing of the rear part also gives a bordered appearance to this protruding part of the lining.
[0008] According to one embodiment of the invention, the or at least one of the seams of the connection, which is at least one seam connection, of each quarter to the rear portion comprises at least one hot-melt sewing thread. Thus, heat can be used for the destruction of the connection without risk of damage to the quarters due to the design of the connection between the rear portion and the quarters.
[0009] According to one embodiment of the invention, the upper delimiting an opening for inserting a foot, the or at least one of the seams of the connection of each quarter to the rear part extends from said opening in the direction of an area of the upper intended to be coupled to a sole.
[0010] According to one embodiment of the invention, the facing and the lining of the rear part are assembled together at least by a so-called assembly seam and the or at least one of the assembly seams of the facing of the rear part and of the lining of the rear part extends parallel to the or one of the seams of the connection of each quarter to the rear part.
[0011] According to one embodiment of the invention, the front part of the upper comprises at least one tip and a vamp, the tip comprises, at least locally, from the outside towards the inside of the upper, a facing and a so-called inner lining assembled to said facing and at least partially overlapping said facing, the tip is assembled to the vamp by a connection comprising at least one seam and the lining of said tip extends projecting from the facing of the tip and from the connection of the tip to the vamp and partially overlaps from the outside of said vamp to form a thermal screen for at least partial protection of said vamp and / or a guide to assist in the disassembly of said tip. The connection of the tip to the vamp is at least one connection of the lining of the tip to the vamp, this connection being able to further associate the toe liner to toe facing. The design of the front portion connection similarly allows for easy removal and replacement of the toe, which is the wear part of the front portion of the upper, while retaining the vamp and quarters, which can be reused to design a new upper with a toe that is aesthetically identical or not to the one previously removed.
[0012] According to one embodiment of the invention, the or at least one of the seams of the connection, which is at least one seam connection, from the tip to the vamp comprises at least one hot-melt sewing thread. Thus, heat can be used for the destruction of the connection without risk of damaging the vamp due to the design of the connection between the tip and the vamp.
[0013] The invention also relates to a shoe comprising at least one upper and one sole, characterized in that the upper conforms to that described above.
[0014] The invention also relates to a method for manufacturing a shoe upper comprising at least one front part, a rear part called a counter, and two quarters arranged opposite each other and each extending from the front part towards the rear part, said method comprising, for each quarter, a step of coupling said quarter by a connection to the rear part, the connection comprising at least one seam, the rear part of the upper comprising, at least locally, from the outside towards the inside of the upper, a facing and a lining called an inner lining assembled to said facing and at least partially covering said facing, characterized in that, at the end of the coupling step, for each quarter,the lining of the rear part extends in projection from the facing of the rear part and from the connection of the rear part to said quarter and comes to partially cover from the outside of said quarter to form a thermal screen for at least partial protection of said quarter and / or a guide to aid in the disassembly of the rear part.
[0015] According to one embodiment of the method, the rod conforms to what is described above. Brief description of the drawings
[0016] The invention will be better understood upon reading the following description of exemplary embodiments, with reference to the appended drawings in which:
[0017] [Fig-1] represents a perspective view of a rod according to the invention in the unassembled state of at least part of the elements constituting it;
[0018] [Fig.2] represents a perspective view of a rod according to the invention in the assembled state of at least part of the elements constituting it;
[0019] [Fig.3] represents a perspective view of a shoe incorporating an upper according to the invention;
[0020] [Fig.4] represents a partial schematic sectional view of the connection between a neighborhood and the rear part;
[0021] [Fig.5] represents a partial schematic front view of the connection between a quarter and the rear part.
[0022] As illustrated in [Fig.l], the invention relates to a shoe upper 1 comprising a front part 2, a rear part 3 called a counter and two quarters 4 arranged opposite each other and each extending from the front part towards the rear part 3.
[0023] The rod 1 delimits an opening 6 through which the foot can be inserted inside the rod in the space between the quarters 4. The interior of the rod 1 is formed by the part of the rod intended to be in contact with the foot in the state in which the foot is inserted into the rod.
[0024] This upper 1 is intended to be assembled to a sole 12 to form a shoe 13 in accordance with [Fig. 3]. Each quarter 4 may be made of leather or fabric. The rear part 3 comprises, at least locally, from the outside towards the inside of the upper 1, a facing 31 and a lining 32 called the inner lining assembled to said facing 31 and at least partially covering the facing 31. The facing 31 may be made of leather or fabric. The same applies to the lining 32.
[0025] Each quarter 4 is coupled by a connection 5 to the rear part 3, in particular at least to the lining 32 of the rear part 3. In the example shown in [Fig. 4], each quarter 4 is coupled by a connection 5 to the lining 32, this connection 5 further ensuring a connection of the lining 32 of the rear part 3 to the facing 31 of the rear part 3. This connection 5 comprises at least one seam 51. As illustrated in FIGS. 4 and 5, for each quarter 4, the lining 32 of the rear part 3 extends projecting from the facing 31 of the rear part 3 and projecting from the connection 5 of the rear part 3 to said quarter 4. This part of the lining 32 of the rear part 3, which extends projecting from the facing 31 of the rear part 3 and projecting from the connection 5 of the rear part 3 to said quarter 4, called the protruding part of the lining, is represented by + in [Fig.5].
[0026] This part of the lining 32 of the rear part 3 projecting from the facing 31 of the rear part 3 partially covers the outside of the quarter 4 to form a thermal screen for at least partial protection of the quarter 4 and / or a guide to assist in the disassembly of the rear part 3, as illustrated in figures 4 and 5.
[0027] This projecting part of the lining 32 of the rear part 3 forms a border of the facing 31 of the rear part 3. This projecting part of the lining 32 of the rear part 3 can, like a flap, be moved away from or brought closer to a quarter to which it is coupled by the connection 5. This connection 5 of the rear part 3, in particular of the lining 32 of the rear part 3 to the quarter 4, which comprises at least one seam, can be made with a hot-melt sewing thread 511. The advantage of this solution is that it is sufficient to heat said seam 51 from the outside to obtain the destruction of the connection between rear part 3 and district 4.
[0028] In the example shown in [Fig.2], the connection 5 of each quarter 4 to the rear part 3 comprises a seam 51 which extends from the opening 6 of the upper 1 towards a zone 7 of the upper 1 intended to be coupled to a sole 12.
[0029] In this embodiment, the facing 31 and the lining 32 of the rear part 3 are assembled together at least by a so-called assembly seam 8. This assembly seam 8 of the facing 31 and the lining 32 of the rear part 3 extends parallel to the seam 51 of the connection 5 of each quarter 4 to the rear part 3.
[0030] Thus, the seam 51 of the connection 5 of the rear part 3, in particular at least of the lining 32 of the rear part 3, to the quarter 4, extends between the part of the lining 32 of the rear part 3 projecting from the facing 31 of the rear part 3, and overlapping the quarter 4 to form a border and the seam 8 for assembling the facing 31 and the lining 32 of the rear part 3.
[0031] The breaking of this connection 5 of each quarter 4 to the rear part 3 can be carried out by heating the connection 5 using, for example, a flow of fluid generated outside the rod 1 and oriented from the outside of the rod 1 towards the rod 1 at the level of said connection 5 to generate a fusion or stitching. It is then sufficient to pull on the projecting part of the lining 32 covering the quarter 4 to obtain a separation of the quarter 4 from the rear part 3.
[0032] In this embodiment, the protruding portion of the lining 32 protects the quarter 4 from any damage under the effect of heat. This protruding portion of the lining 32, covering the quarter 4, can also, at the time of a break in the connection 5 by cutting, be used as an element for protecting the quarter 4 when a cutting tool, such as scissors, is used to ensure a break in the connection, as illustrated in [Fig.5].
[0033] This protruding portion of the lining 32 can also be used as a cutting guide when it is moved away from the quarter 4.
[0034] The front part of the upper 1 comprises, for its part, at least one end 9 and a vamp 10. The end 9 comprises at least locally, from the outside towards the inside of the upper 1, a facing 91 and a lining 92 called the inner lining assembled to the facing 91. This lining 92 comes to at least partially cover the facing 91. The end 9 is assembled to the vamp 10 by a connection 11 comprising at least one seam 110. This connection 11 which couples at least the facing 91 of the end 9 to the vamp 10 can further couple the facing 91 of the end 9 to the lining 92 of the end 9. The lining 91 of the end 9 extends projecting from the facing 91 of the end 9 and projecting from the connection 11 of the end 9 to the vamp 10.
[0035] This projecting part of the lining 92 of the end 9 partially covers the outside of the flap 10 to form a thermal protection screen at least partial of the slap 10 and / or a guide to help with disassembly of the end 9.
[0036] In a similar manner to what has been described above, for the rear part 3, the seam 110 of the connection 11 of the toe 9, in particular at least of the lining 92 of the toe 9 to the vamp 10, may comprise a hot-melt sewing thread. This seam 110 of the connection 11 of the toe 9 to the vamp 10 extends transversely to the longitudinal axis of the upper 1 and adjoins the so-called front edge of the vamp 10.
[0037] The facing 91 and the lining 92 of the end 9 can be assembled together by an assembly seam which preferably extends parallel to the seam 110 of the connection 11 of the end 9, in particular at least from the lining 92 of the end 9, to the vamp 10.
[0038] Thus, the seam 110 of the connection 11 between at least the lining 92 of the end 9 and the flap 10 extends between the part of the lining 92 of the end 9 which projects from the facing 91 of the end 9 and overlaps the flap 10 to form a border and the assembly seam of the facing 91 and the lining 92 of the end 9.
[0039] Again in this embodiment, the breaking of the connection 11 between the end 9, in particular the lining 92 of the end 9, and the slap 10, can be carried out using a flow of hot fluid, such as hot air, generated outside the rod and oriented in the direction of the rod and / or using a cutting tool, such as scissors.
[0040] The manufacture of a shoe upper 1, as described above, is carried out easily. Thus, in the coupling step, for each quarter 4, the lining 32 of the rear part 3 extends projecting from the connection 5 of the rear part 3 to the quarter 4, and projecting from the facing of the rear part 3 and comes to partially cover the outside of the quarter 4 to form a thermal screen for at least partial protection of the quarter 4 and / or a guide to assist in dismantling the rear part 3.
[0041] Similarly, at the end of the step of coupling the end 9 to the vamp 10, the lining 92 of the end 9 extends projecting from the connection 11 of the end 9 to the vamp 10 and projecting from the facing 91 of the end 9 and comes to partially cover the exterior of the vamp 10 to form a thermal screen for at least partial protection of the vamp 10 and / or a guide to assist in the assembly of the end 9.
[0042] The dismantling of a shoe 13 equipped with an upper 1, as described above, is therefore carried out easily using a hot fluid and / or a cutting tool. The toe 9 and the rear part 3 can be replaced with a toe and a rear part that are aesthetically identical or not, while the quarters and the vamp are preserved without having been damaged by the dismantling operations.
