  • Other features and advantages of the invention will become apparent on reading the following detailed description of embodiments of the invention, given by way of example only and with reference to the drawings.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows diagrammatically a sectional view of a shoe.
  • FIG. 2 shows diagrammatically an example of a sole assembly that can be implemented in the shoe of FIG. 1.
  • FIG. 3 shows diagrammatically a detail of an exemplary sole assembly which can be implemented in the shoe of FIG. 1.
  • FIG. 4 shows diagrammatically a detail of the securing of a shoe upper on the sole assembly shown partially in FIG. 3.
  • DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
  • FIG. 1 shows a shoe 10 having a sole assembly 12 and a shoe upper 9.
  • As shown in FIG. 1, the sole assembly 12 comprises two frame members 1, 2, namely a lower frame member 1 and upper frame member 2. The two frame members 1 and 2 are located one above the other. That is to say that when the shoe 10 is worn, the upper frame member 2 is disposed above the lower frame member 1. The two frame members 1, 2 are substantially of the same length.
  • Outsoles 7, 8 may conventionally be mounted on the lower frame member 1. These outsoles 7, 8 are wear parts that can be relocated when worn, to extend the life of the shoe 10. The outsoles 7, 8 may also have a non-slip function. The outsoles 7, 8 are formed by inserts fixed on and below the lower frame member 1. These outsoles 7, 8 may especially be of natural or synthetic rubber. Outsoles 7, 8 can be adhesive bonded on the bottom frame member 1. According to a preferred embodiment, the outsoles are fixed to the bottom of bottom frame member 1 by means of pins integral with the outsoles and tightly received in holes of complementary shape formed in the lower frame member 1.
  • Furthermore, a first anti-shock comfort padding 6 may be fixed to the upper frame member 2.
  • The two upper 1 and lower 2 frame members are made of any material known to those skilled in the art as being suitable for the manufacture of a conventional sole. Thus, the lower frame member 1 and upper frame member 2 may in particular be made of wood or compressed chipboard derivatives thereof, of metal such as aluminum or other light alloys, of plastics material, of resin material or of compressed fibers. These materials have sufficient rigidity to ensure a secure fit and stability for the wearer of the sole in a shoe provided with the sole assembly. The choice of a plastics material allows the two lower and upper frame member to be produced by molding.
  • In one embodiment, the upper frame member 2 is made of metal by stamping. The upper frame member 2 has in this case a thickness of the order of a few tenths of a millimeter, particularly a thickness between 4 and 5 tenths of a millimeter. Such a frame member 2 is lightweight, and has high rigidity and ease of installation.
  • The two upper 1 and lower 2 frame members are also articulated relative to each other. Thus, the upper frame member 2 has at least one degree of freedom in rotation about an axis perpendicular to the plane of FIG. 1 relative to the lower frame member 1. As illustrated in the drawings, the two frame members are articulated at the area for receiving that part of the foot corresponding to the base of the metatarsal bone.
  • The articulated mounting of the two frame members 1, 2 relative to each other improves the comfort of the user, while ensuring a function of elevation of the wearer. Indeed, as a result of the wearer putting his or her weight forward, the rear of the upper frame member is raised, providing the wearer with the same effect as a heel, for example. The weight of such a sole assembly is also reduced relative to a conventional platform sole, which is solid. Furthermore, the degree of freedom between the lower frame member 1 and upper frame member 2 allows the upper frame member 2 to remain in contact with the foot of the wearer of the shoe 10 during walking.
  • The articulation of the frame members 1, 2 is achieved in the example of FIG. 1, by means of a component 5. Component 5 comprises two cylinders 51, 52. Cylinder 51 is received in a complementary housing 11 formed in the lower frame member 1. The other cylinder 52 is received in a complementary housing 21. In FIG. 1, the two cylinders 51, 52 are of circular cross-section to ensure the articulation of the upper frame member 2 relative to the lower frame member 1.
  • It should however be noted that by the term cylinder we mean a surface defined by a closed curve and a direction of extension. Thus, a cylinder is a priori of any section. It is sufficient a priori for one of the two cylinders 51, 52 to be of circular cross-section to ensure the articulation of the upper frame member 2 relative to the lower frame member 1.
  • The cylindrical shape also allows easy mounting of component 5 in the two housings 11, 21 by introducing it with a translatory movement from one side of the two frame members.
  • The component 5 is preferably made of a synthetic rubber or natural rubber to permit cushioning of the movement of the two frame members one relative to the other.
  • In this case, the component 5 can, in the embodiment illustrated in FIG. 2, also form a tongue 53 disposed between the lower frame member 1 and upper frame member 2, to improve the cushioning provided by the component 5 between the two frame members 1, 2.
  • To limit the amount of movement of the upper frame member 2 relative to the lower frame member 1, in the example of FIG. 1 means for damping/limiting movement, notably pivoting, of one frame member relative to the other are provided. In the example of FIG. 1, these movement damping means are in the form of two pieces of resilient material 3, 4 interposed between the lower frame member 1 and upper frame member 2. The resilient material is for example of synthetic rubber or natural rubber. Obviously, other movement damping means may be implemented such as pouches of fluid, particularly viscous fluid. In addition to limiting the displacement of the upper frame member 2 relative to the lower frame member 1, the movement damping means are able to damp the pivoting movements of the upper frame member 2 relative to the lower frame member 1. For example, when the foot lands on the ground, the movement damping means—in this case the pieces of resilient material 3, 4—damp/limit the pivoting of the upper frame member 2 relative to the lower frame member 1. This further increases comfort for the wearer.
  • The two pieces of resilient material 3, 4 are here arranged one at each side of the articulation between the lower frame member 1 and upper frame member 2, to facilitate assembly of the sole assembly 12 and ensure the holding in position of the two pieces of resilient material, deflection of the upper frame member 2 relative to the lower frame member 1 being limited at both sides by the pieces of resilient material.
  • It should be noted here that by choosing pieces of resilient material 3, 4 of varying sizes, it is possible to change the height of the wearer's heel and thus it is possible to boost the height of the wearer of the shoe 10 to a greater of lesser degree.
  • To ensure the positioning of the pieces of resilient material, they are received in recesses of complementary shape formed respectively in the lower frame member 1 and/or upper frame member 2. In view of this requirement and for ease of manufacture of sole assembly 12, the pieces of resilient material 3, 4 have a ball shape and are received in dome-shaped or spheroidal cuplike housings.
  • It should be noted that the sole assembly 12 as described above has the advantage of being able to be mounted/removed without special tools. This facilitates the replacement of components of the sole assembly 12.
  • To assemble this sole assembly 12, it is sufficient to introduce component 5 by sliding it into two suitable housings respectively of lower frame member 1 and upper frame member 2. After this, one of the two pieces of resilient material, where appropriate in a recess of corresponding shape, is fitted. Fitting is facilitated by the absence of the second piece of resilient material, which allows the lower frame member 1 and upper frame member 2 to be pivoted one with respect to the other, in order to fit the piece of resilient material. A force is then exerted on the upper frame member 2 and/or on the lower frame member 1 at the piece of resilient material which has already been fitted, to clear a sufficient space for fitting the second piece of resilient material.
  • Assembly of the sole may continue by securing the shoe upper 9 onto the sole assembly 12 to form a shoe. For this, means for securing the shoe upper on the sole assembly are implemented. The securing means for the shoe upper can in particular consist of staples, glue or nails.
  • According to a particularly advantageous embodiment, the securing means of the shoe upper on the sole assembly are attachable and detachable, preferably manually. This makes it possible to assemble a shoe without special tools. Furthermore, this may enable the sole assembly and/or the shoe upper to be replaced one independently of the other. Such securing means are, for example, snaps, a zipper or lacings.
  • FIGS. 3 and 4 illustrate an example of means for securing the shoe upper 9 of sole assembly 12, more particularly on the upper frame member 2.
  • According to this example, metal plates 101, 102, 103 are fixed to the upper frame member 2. In this case, these metal plates 101, 102, 103 are nailed to the upper frame member 2, the frame member 102 being made of wood. Of course, other securing means of the plates 101, 102, 103 onto the upper frame member can be considered such as for example glue. The plates 101, 102, 103 may also be attached by insert molding the upper frame member 102, when the latter is made of plastic material, in particular EVA (Ethylene-vinyl acetate).
  • The plates 101, 102, 103 have holes 104 which are located opposite housing 105 formed in the upper frame member 2. The holes 104 are adapted to receive screws 106. Preferably, the screws 106 are quarter-turn screws to allow rapid assembly and dismantling.
  • These quarter-turn screws make it possible to trap or pinch flanges of shoe upper 9 between the metal plate 103 and the head of screw 106. A washer 107 may be interposed between the head of the screw 106 and the shoe upper 9 to prevent unintended loosening of the shoe upper.
  • Of course, the present invention is not limited to the embodiments described above by way of example. The invention on the contrary covers many variations of these embodiments that are accessible to those skilled in the art.
  • For example, one of the two frame members of the sole assembly may include a projection (or protrusion or bead) of a circular-cylindrical shape or having at least a portion of circular section designed to be received in a housing of complementary shape formed in the other of the two frame members to permit articulation of the two frame members one relative to the other.
  • The invention also relates to a ready-to-assemble unit (or kit) comprising the necessary elements to produce the sole assembly as described above and to a ready-to-assemble kit comprising the elements necessary for producing a shoe comprising the sole assembly, a shoe upper and means for securing the shoe upper on the sole assembly.
