Definitions
- the subject of the present invention is a method and a heating device for thermoforming the interior of a shoe with a rigid external upper.
- such shoes such as for example ski boots, or even mountain boots, ice skating shoes, inline skating shoes, etc.
- an external upper generally constituted by a shell made of rigid plastic material but which can also be made of thick and rigid leather for mountain boots for example, which must ensure that the foot-ankle assembly is held, and in particular avoid twisting the ankle, and allow good transmission forces exerted by the foot, either for driving the ski or the gliding member, or for holding on a slope for walking in the mountains
- an inner lining generally consisting of a removable liner, and made of more flexible materials such as foam.
- thermoformable material such as polyethylene which once brought to a temperature of approximately 120 °. -140 ° can be conformed to both the user's foot and the outer shell, until it perfectly matches the shape of the user's foot
- JP 246 876 Other solutions, proposed for example by JP 246 876, consist in heating the interior lining after having removed it from the boot, that is to say simultaneously by the interior and the exterior after having placed it in an appropriate heating enclosure. , or only from the outside, until it reaches the uniform thermoforming temperature, of the order of 120 ° -140 °, desired
- heaters generally constituted by a pipe sending hot air inside the ski boots, in order to dry them or to warm them slightly before use.
- Such devices are not designed for a temperature above 40 ° and could not be applied directly to a thermoforming of interior linings at a temperature of the order of 120 ° -140 ° without risk of damaging them.
- the object of the present invention is therefore to remedy these drawbacks and to propose an improved method and device for heating the inner linings of shoes which allows them to thermoform while being of reduced cost and size, easy and quick to implement, and without imposing long, tedious manipulations, and likely to introduce errors.
- this method allows a very simple and very rapid implementation because it imposes no manipulation, exit, reentry, inside the shoe of the interior lining. It is also compatible with a lining fixed inside the shoe. Finally, it has been observed, in a way that is not obvious a priori, that direct heating of the lining arranged inside the boot does not risk damaging or softening the outer upper of the latter, since the temperature obtained outside of this lining does not in fact exceed 80 ° C. for a thermoforming temperature of the order of 130 ° C.
- the method also consists in placing the shoe flat and upside down with respect to the hot air distribution system, so that the heat remains trapped inside the shoe.
- the hot air which always tends to rise, remains trapped in the areas of the heel / instep of the shoe which are found because of this position most in height and one therefore obtains a more homogeneous and constant heating temperature in these zones which are precisely the most sensitive zones and to be thermoformed.
- the heating device for implementing the method according to the invention comprises:
- the means for positioning the nozzle inside the shoe consist of a seat capable of receiving the upper of the shoe.
- the seat thus guarantees the fitting, upside down, of the shoe. that is to say with its thermoforming zones located the highest.
- the means for positioning the nozzle inside the shoe also include a stop limiting the introduction of the latter inside the shoe, and participating in the positioning of the nozzle at the inside the shoe, this stop constituting moreover means for closing the opening of the upper of the shoe between this nozzle and the rear part of the upper, so as to channel the hot air on the neck part of foot / tongue of the interior trim.
- FIG. 1 is a perspective view of a heating device according to the invention in use with a ski boot
- FIG. 2 is a sectional view along ll-ll of FIG. 1,
- FIG. 3 is a sectional view along lll-lll of Figure 1.
- the heating device according to the invention of Figures 1 to 3 is shown in use with alpine ski boots, it is of course not limited to such an application and can be designed and used with any other type of boot having a rigid outer rod, not necessarily made of plastic and which may be, for example, very thick and rigid leather for a walking / hiking shoe, and an inner lining of comfort, fixed or removable, at least partially thermoformable.
- the heating device 1 appears externally as a kind of fairly flat box and of substantially paralepiped shape intended to be placed flat by its underside 1b on a ho ⁇ zontale surface.
- This device has on its upper face 1a two elongated and curved depressions 2, and each intended to constitute a seat for receiving and supporting a shoe 11.
- the profile of the seat of each shoe is designed so as to provide stable support for the shoe placed upside down, heel upwards, the shoe being in fact supported on the seat 2 by its upper 12, ie its upper part of the foot / instep.
- the profile of the seat 2 corresponds to an average profile of the upper of the shoe as a function of the sizes and possibly of the shoe model. The important thing is to obtain stable support for the shoe in this inverted position.
- each seat 2 is also provided a depression 3 of substantially rectangular shape intended to receive and serve as housing for each of the heating nozzles 4, outside the periods of use and for transport.
- Each heating nozzle 4 is constituted by a slightly curved tube at its free end 4a to adapt to the internal shape of the shoe.
- the curve of this tube can be modified according to the type of shoe to be thermoformed.
- each nozzle is provided over its entire length with external peripheral fins or grooves 5 intended to allow a more homogeneous diffusion outside the nozzle of the hot air circulating outside this, and also to avoid the risk of burns when gripping the nozzle, even in the event of hot air blowing.
- These nozzles 4 may have a circular or rectangular section.
- each nozzle is closed at its free end 4a, but is provided near this end with at least two diametrically opposite openings 6.
- openings can be arranged so as to be located opposite the heel and instep parts 13 of the lining of the shoe made of thermoformable material. They can also be arranged at 90 ° relative to the arrangement shown so as to heat more particularly the lateral zones, corresponding to the malleoli of the foot, of the shoe also made of thermoformable material.
- the closure of the nozzle 4 at its free end 4a is particularly important to avoid deterioration of the outer sole part 15 of the lining by hot air, in particular when the latter is not made of thermoformable material or when the shoe is threaded too far on the nozzle 4.
- the nozzle would be shaped so as to send hot air uniformly over the surface of this insole.
- Another opening 7 is also provided on each nozzle so as to be opposite the tongue portion 14 of the lining of the shoe.
- each nozzle is connected at its other end 4b to a pipe 8 for supplying hot air.
- each nozzle has at its upper part a half cone 10 intended to cooperate with the upper end 16 of the shoe to limit the penetration of said nozzle inside the shoe.
- This half cone 10 is in the example shown consisting of a series of three half discs 10a each corresponding to the upper half opening of a shoe according to extreme and median sizes.
- the smallest disc 10a corresponds to a small size and the largest disc corresponds to a large size.
- the cone 10 could be produced in another way, it could also be replaced by other abutment means constituted for example by a rod of adjustable length, not shown in the drawing, at the free end 4a of nozzle and cooperating with the bottom 15 of the shoe to maintain the desired spacing between the latter and the nozzle 4.
- the cone 10 also has the additional advantage of closing the upper half-opening of the shoe, that is to say the opening part of the shoe disposed between the rear of this shoe and the nozzle, and therefore prevent hot air from escaping through this opening.
- the hot air can only come out from below the nozzle 4 and a privileged direction of air circulation, represented by the arrows 20, is created in the heel / instep area, malleoli of the shoe and along the tongue 14 of the shoe.
- Such a construction therefore optimizes the use of hot air and the speed and quality of heating.
- the cone 10 also participates in the maintenance of each shoe on its seat 2 and in the correct positioning of the nozzle inside the latter by adapting to the contour of the rear half-opening of the shoe.
- Figure 2 shows the desired optimal positioning of the nozzle inside a shoe, namely relatively centered relative to the inner lining thereof.
- an elastic stop such as a blade / spring (not shown in the drawing), could be provided on the lower part of the nozzle, that is to say opposite the cone 10, to cooperate with the instep / tongue part of the trim and perfectly guarantee the desired positioning of the nozzle.
- FIG. 3 shows more particularly the supply of hot air to each nozzle 4.
- This supply occurs from a source of hot air 18, of a type known per se and not described further on, and producing air hot at a temperature between 120 ° and 140 °, and preferably at 130 ° C.
- This hot air is channeled through a pipe 17 which is connected to the supply pipe 8 of the nozzles 4.
- a switch 21 placed on the upper face 1a of the device makes it possible to start / stop the heating device.
- Each of the nozzles 4 is mounted directly on the tubing and communicates with the interior thereof by an opening 8a.
- each nozzle 4 is mounted with a possibility of relative pivoting on the tube 8, stops 19 provided on the upper part 1a of the heating device limiting the pivoting angle of these nozzles.
- This pivoting in fact allows a certain movement of the nozzles in order to facilitate their positioning inside each shoe, and their adaptation to the different sizes.
- thermoforming of shoe lining not limited to a removable interior lining, such as the methods known up to now and can therefore be used for thermoforming fixed interior trim.
- thermoforming of the heel / instep and perimeter zone of an inner lining which are the preferred thermoforming zones. It could obviously be adapted to other thermoforming zones.
