Definitions
- An object of the present invention is to improve the conditions of maintenance of shoe heels, by allowing the user to carry out this maintenance himself at home, very quickly, by means of removable, self-changeable and interchangeable heels. of the same height.
- Another object is that the pair of shoes be of variable style by the choice of pairs of self-changeable heels of different style in the geometric shape and in the decoration.
- Another object is that the fixing of the heels and / or the bonbouts (ends of wear) is carried out by only intrinsic means.
- Another aim is to ensure that this ease of changing the heels and the heels does not jeopardize the necessary good adhesion of the heel on the heel, and of the heel on the sole.
- Another object is that the fixing means are simple, reliable, and easy to implement, and therefore at a lower cost of tooling and manufacturing.
- the prior art discloses heel designs comprising a support part and a replaceable wear part, elastically connected to the support, as in the patents: U.S. 411,326 / 2,751,694 and U.S. 109,768 / 3,063,168.
- the centralized elastic means is, depending on the variant embodiments, a drilled leaf spring, an annular spring on a tapered support, a spring helical, a tubular spring forming an elastic pin.
- Figure 1 is a rear view of a shoe showing the wear 1 characteristic of a heel. Seen from the back, we can see that the aesthetic state of the heels is particularly visible. To remedy this condition, it is practical to have replacement heels at home that meet a need for immediate improvement of this aesthetic condition, in particular for a careful outing.
- FIG. 2 is an exploded side view, in partial section, of a shoe comprising a special sole including a protrusion 2, forming a heel support designed to assemble a wear heel 3, hollow and removable, and so that there is interpenetration of the sole and heel.
- Said support 2 is in the form of a shoulder tenon 4 comprising concavities 5 "and a cavity 6 containing an elastic means such as a leaf spring 7 including a possibly extended drilling of a nut 8.
- the cavity is closed by a shank 9.
- the flat heel 3 are made of a non-slip material such as an elastomer molded on a central screw 10 forming a tapered means intended to be screwed onto said leaf spring.
- This heel is hollow by a cylindrical mortise 11, the rim of which comprises convex prominences 12 intended to penetrate into the concavities 5, so as to oppose rotation of the heel when the shoe is in use.
- the means 5, 12 constitute rotation brakes by elastic self-locking, the blocking force of which is progressive and increases with each turn of the heel.
- the heel made of a flexible material is stiffened by a frame 13 forming a framework preferably made of a rigid plastic material, for its good application against the sole. By means of screwing the heel, it is easy to assemble and disassemble it repeatedly, with the same quality of application, because of its peripheral rim reinforced by said frame.
- Figure 3 is an elevation view of the wear and removable heel 3 of Fig.2.
- Figure 4 is a rear view and partially in section of a shoe with a high heel, removable and self-changeable, comprising: - a heel support whose external geometric shape is divided into two parts, an upper part 14 for attachment to a insole 15 reinforced with a shank 16, and a tapered lower part 17 forming a tenon for a preferential sliding assembly of the heel 18 on its support, so that the heel is free to abut against the flap of the rod 19 of the shoe, before abutting, possibly, against the support.
- This (14, 17) is also applied against the flap of the upper of the shoe, and against the thinned rear part of an outer sole 20.
- This support comprises therefore a narrowed, substantially cylindrical lower part 17, which may include a low release taper, 1 to 2%, and whose axis is perpendicular to the base of the heel 18.
- the heel support has an external shape which corresponds substantially at the inner cutout of the heel, so that the metal reinforcement 21, of certain pointed heels, also appears in the heel support.
- the tapered part comprises a peripheral notch 22 for the engagement of an annular spring 23.
- the said sliding assembly is completed by means of angular stabilization of the heel, relative to the longitudinal axis of the sole, this means stabilization is effected by interpenetration of the support and the heel, according to the example of a prominence 24 penetrating into a cavity 25 of the heel.
- the heel includes: - a lower cavity in which is engaged forcibly a drusure end 26 (bonbout); - a curved and highly biased rear part 18 unlike the high rear part 27 allowing a lowered heel point on the ground when driving a car where the shoe is tilted backwards due to its position on the pedals control, this lowered fulcrum protecting the rear of the upper of the shoe which, if damaged, cannot be replaced unlike the heel.
- the protrusion 24 will be of different width for another support provided for another heel height.
- the means for centralizing and concentrating the assembly and its fixing are therefore provided by the tapered part 17 of the heel support, and provided by the annular spring 23 limiting said elastic fixing to a single anchoring point.
- Figure 5 is a rear view and partially in section of a shoe without its heel, and according to some variant with respect to fig.4. These variants show the choice between a helical spring 29 surmounted by a nut 30 which are introduced into a cavity of the heel support (14, 31), the annular spring 23 (fig. 4) intended to be engaged in the peripheral notch. 22 of a hollow metal extension 31 forming the tapered part of said support.
- the top of the wide part of the support comprises a concavity 32 allowing a well distributed support on the soles 15, 20, and / or on the flap of the upper 19 of the shoe.
- FIG. 6 is a rear view in partial section of a high heel intended to be assembled with the support of fig.5.
- This heel 33 comprises: - a conical cavity 34; - A recessed cavity 35 for a preferential sliding adjustment with the tapered part 31 of the support fig.5; - The concavity 23 of angular stabilization adjusting with the prominence 24, fig.4. - a lower cavity 36; - a notch 37 which can be bevelled; - notch 28.
- Figure 7 is an elevational and sectional view of a bonbout 41 of a polymeric material molded on the flat head 42 of a rod 43 partially threaded 44 and provided to join a removable and self-changeable heel such as 33 on a support such that (14, 31).
- the rod 43, or the bonbout 41 includes a protrusion (45, 46) designed to engage deeply in the lower cavity 36 of the heel, in order to oppose its accidental release of the support when the bonbout is completely worn .
- the spring 29 is gradually compressed to apply the heel 33 against the soles and / or against the flap of a shoe upper, and apply the bonbout against the heel, so that they interpenetrate with progressive blocking of the rotation of the good tip, due to the prominence 46 penetrating more and more strongly into the notch 37.
- the tensile force of the spring will be sufficient to prevent accidental rotation of the bonbout when using the shoe.
- the means 37, 46 allow a precise and stable position of the bonbout 41.
- Figure 8 is an elevational view in section, of a bonbout 47 secured to a smooth, unthreaded rod 48, unlike the rod 43, fig.7.
- the bottom of the rod may be non-smooth for good attachment of the protrusion 49 projecting from the upper plane of the bonbout.
- Figure 9 is a top view of Fig.8, detailing the prominence 49 of non-circular shape, intended to engage deeply in the cavity 36 of suitable shape, the heel 33, Fig.6, so as to s' to oppose a rotation of the bonbout 47, and to prevent an accidental release of the heel when the said bonbout is completely worn out.
- Figure 10 is an elevational view of a bonbout 50 secured to a rod 51, smooth, hollow and split, the lower part, not smooth, is enclosed by a protrusion 52.
- the rod is réa.lrise in a blade of hardened steel, or in another elastic material, of small thickness, to form a tubular spring with transverse elasticity, and quite flexible.
- the blade may be wound less than one turn and include a slot, or be wound more than one turn and not include a slot.
- the lower, non-smooth part of the rod can be pierced with small transverse holes, for the attachment of the protrusion 32. of the bonbout molded on the rod.
- FIG. 11 is a top view of FIG. 10, detailing a variant form of the protrusion 52. This is circular, but eccentric of the rod 51, and it is designed to engage in the cavity 36 of adapted shape, fig. 6
- FIG. 12 is a partial view, from the side and in section, of an outer sole 54 glued to a shoe upper 19, and the rear part of which is designed to assemble a removable, self-changeable heel, such as the heels 18, 33, fig. 4 and 6.
- the sole 54 includes a difference in thickness 55 for slight embedding of the front edge of an autochangeable heel.
- the arch of the sole is stiffened by a shank 56 which may or may not be integral with a heel support comprising the upper part 14 clamped by a protrusion 58 of the sole 54.
- This protrusion is preferably conical, and possibly non-circular, and it is molded with the sole preferably made of a polymer material.
- this prominent composition 58 enclosing the support (14, 57) takes the external geometric shape of the support (14, 17), (14, 31) of fig.4 and the variant fig.5.
- the advantage of this composition is to simplify the manufacture of the shoe specially designed for the self-changeable heel, by obtaining better positioning and fixing quality of a heel support on the outsole.
- the insole (first fitting) is not necessary, and a single insole can be arranged to serve as a sockliner and to satisfy the interior aesthetics of the shoe.
- the means of connecting a self-changeable heel to its support comprises an annular spring, for example a spiral 59, engaged in a cavity extending the hole 60.
- the fixing by an elastic connection of the heel on its support, is sufficient, the causes the heel to be regularly subjected to a vertical thrust applying it against the outer sole and / or against the flap of the upper of the shoe, each time it presses against the ground.
- the shank 56 and the support (14, 57) can be made in one single piece, monobloc, molded from a polymer material.
- Figure 13 is an elevational view of a support such as (14, 57) fig.12, slightly modified.
- This modification relates to the cavity 61 extending the hole 60.
- This cavity is a cylindrical hole with a diameter smaller than the hole 60, and not containing an elastic means such as an annular spring.
- a tubular spring with transverse elasticity, is provided by the pin 51, fig.10, secured to a bonbout such as 50 extended by the prominence 52.
- the elastic pin is introduced into the support by the hole 60 to be tightened elastically in the hole 61, this tightening temporarily reducing the diameter of a part of the pin by allowing blocking of the heel by the bonbout 50 at the end of the introduction of the pin into the support.
- the top of the support includes a mortise 62 for forcibly engaging a metal shank such as 56, fig.12.
- Figure 14 is a sectional view of a support such as (14, 57) fig.12, comprising: - a projecting rod 63 with transverse elasticity.
- the bonbout such as 47, 50 no longer comprises the rod 48, 51, but only a cavity in the prominence 49, 32 allowing its mounting on the rod 63 after the heel 33 is engaged on the support.
