  The present invention relates to an alpine or trekking shoe equipped with a source of energy which includes an energy consuming device such as, for example, a heating device. Ski boots are already known in which they are incorporated in order to improve the comfort of the carrier of the heating devices is of the electric type with heating resistor or type h liquid or gaseous fuel which use in this a fuel tank and a burner housed in the shoe Heating devices with liquid or gaseous fuel The advantage over electric devices is that they provide greater autonomy and, over a relatively long period of time, prevent the desired comfort temperature inside the heating system. Heaters using liquid fuels such as as described for example in patents IT 1 136 269 and FR A 2 080 146 c generally include a rechargeable liquid fuel burner which is placed under a heat diffusion plate incorporated in the sole of the shoe so as to extend as close as possible to the foot of the wearer of the shoe Other heating devices that use a Gaseous fuel comprises a gas tank fed through a valve, a catalytic burner, all these elements being also housed completely in the sole of the boot. Such gaseous fuel heaters are described, for example, in the Italian Utility Model 196850. and in international patent application WO86 / 05663. These gas-fueled heating devices are of the type with a reservoir of water, and it is therefore necessary to provide in the sole of the shoe which contains the reservoir an orifice through which the internal gas tank can be connected to a source of heat In general, all the heating devices known to be of the electric or liquid fuel or liquid type have the disadvantage that once heating is started or stopped, this heating can only be obtained by manual intervention of the heater. In other words, the latter must think about cutting the heating when he leaves his shoe and it can obviously happen that he forgets to proceed with this maneuver, which then results in a continuation of the heating of the shoe off a depletion The present invention aims to remedy these disadvantages by providing a shoe provided with means automatically causing the power supply to be cut off as soon as the wearer of the shoe loosens the power supply. stem of this ci For this purpose this alpine ski boot or ran given with a rod provided with means of tightening e of this rod this shoe being equipped with an energy source supplying an energy consuming device such as a heating device and a device com mandant a power supply member of the energy consuming device connected between the energy source and the consumer device is characterized in that it comprises means actuated by the gripping means of the upper of the boot in order to allow the opening of the energy-feeding member only when the upper of the boot is tightened and to automatically cause the closure This power supply device incorporated in the shoe may be a heating device of the electric type and in this case the means actuated by the clamping means of the upper of the shoe act on an electrical switch connected between a source of electrical energy and a heating unit However, in this case, the means actuated by the rod locking means of the boot act on a device commnndant a faucet connected between a gas tank or the fuel liquid and a fuel valve.

The gas cartridge 11 is disposed vertically with its gas outlet port directed downwards.

  the following description we will consider that the meaning

  "Vertical" is the one in which shank 12 extends while in fact the posterior wall of this shank is slightly inclined towards 1 forward. The gas cartridge 11 is connected at its lower end to a supply member 13 constituted by a set forming a valve and regulator including 1 opening and closing control member is constituted by a finger 14 projecting from] the outside of the valve body 13 and movable in a vertical light of this body The finger 14 is pushed down towards the its opening position by a return spring 14a housed inside the valve regulator 13. The control finger 14 of the valve 13 is actuated by a tab 15 forming part of a device 16 for controlling the gas supply This device 16 acts also on a pusher 17 of an igniter 18 for example of the piezoelectric type which Pst -reliee by the electrical conductor 9 h 1 electrode 8 to produce a spark dal The gas supply control device 16 acting on the tap 13 comprises two substantially vertical plates 1 adjacent to each other contained in vertical and longitudinal planes. namely, a relatively small manual control plate 19 and a plate 21 for actuating the valve 13 of greater height extending both above and below the plate 19 The plate 21 of the tap 13. of general shape Rectnnlaire door h is lower the tab 15 s extending under the finger 14 and in contact with it ci The plate 19 manual control has substantially the shape of a C open to I nr rière and it comprises a vertical soul 19a extended b its two ends respectively by two lower wings 19b and upper 19c The lower wing 19b serves i nc tionner the pusher 17 of 1 piezoelectric igniter 18 and is housed between the upper surface of this pusher 17 and an internal projection 22 of the rear wall The upper flange 19c of the manual control plate 19 extends to 1 outside the rear wall of the rod 12, passing through the hob. Through a light 23 elongated in the vertical direction At 1 outer end of this wing 19c is fixed a control button 24 By ail their two plates 19 21 are urged constnmment upwardly by a compression spring 25 bearing on the upper face The two plates 19 and 21 are coupled to each other by means allowing relative vertical movement of the manual control plate 19 with respect to the actuating plate 21. manual control 19 carries two lugs 26 aligned in the vertical direction and which are respec tively involved in lights 27 which are formed in the actuating plate of the valve 21 and which are aligned in the vertical direction The manual control plate 19 also comprises at its upper part a tab 19d extending upwards and acting on a pawl 28 which is articulated on the upper part The pawl 28 is constructed as a lever with two branches extending in the direction of the rear wall of the rod 12. The lower leg 28a of the pawl 28 is located in the plate 21 of the tap around a horizontal and transverse axis 29. is in contact. at its end with an upper end of In actuating lug 19d and the upper branch 28b of this pawl extends upwardly to the rear wall of the rod 12 The pawl 28 is biased in the senni of the needles of a watch by a spring 31 so that its upper branch 28b is pushed constantly towards the rear wall of the rod 12 The ski boot shown in Figure I is provided with means for clamping its rod 12 around the bns of the leg of the skier In this embodiment, these clamping means consist of cables 32 surrounding the upper part of the rod and which are connected to a clamping device of any known type which can be operated manually by the skier. The legs extend behind a portion 33 of the posterior wall of the rod 12 which is cut so as to constitute a movable flap. More particularly, this flap 33 is delimited. by a U-shaped cut, it remains adjacent to the upper part of the posterior wall of the rod 12 and is detached from the remainder of the wall of the rod 12 along its two lateral and vertical edges and its lower edge. zontal and transverse 33rd. this lower edge being intended to constitute an abutment for 1 end of the upper branch 28b of the pawl 28 The flap 33 has on its part o support the cables 32 clamping the lower leg. a thickness going downwards so well

  that the flap 33 has a vertical and longitudinal section.

  substantially the shape of a trapezium whose large base constitutes the lower edge 33a forming a stop of the flap 33. Moreover, this flap 33 is solicited by a spring 34 which tends to

  to push it towards 1 outside In rest position.

  -c that is to say when the rod 12 is not tight around the lower leg of the skier the flap 33 is in the position shown in Figure 3 and in this position its inner face 33b is flush with the face internal of the posterior wall of the rod 12 while its outer face 33c extends outwardly towards 1 outside and downwardly.

  spring 34 of the flap 33 is advantageously constituted

  killed by a spring arched blade which is fixed at its upper end for example by means of a rivet 35 h the upper part of the rear wall of e rod 12 and whose lower arched. concavity turned towards the flap 33 is in abutment against the inner face 33b of the locking flap 33 When the skier. after socking his shoe tightens the rod 12 thereof around his lower leg by means of the cables 32 1 action exerted by these cables 32 on the outer face 33c of the flap 33 causes I depressing this flap 33 to 1 inside the rod in this position the upper branch 28b of the pawl 28 which is in abutment against the lower part of the inner face 33b of the flap 33 is pushed accordingly. slightly inwardly and the gas supply control device 16 is normally in the closed position. The manual control plate 19 is in fact pushed into its upper extreme position by the spring 25 position in which its lower wing

  l9b is in contact with the projection 22.

  Actuation of the valve 13 is also pushed by the spring 25 in the upper extreme position and its lower leg 15 keeps the actuating finger 14 of the valve 13, in its upper extreme position correspon

when closing this faucet.

  If the skier wishes to start the heater. it presses down on the control button 24, which has the effect of causing the two plates 19 and 21 to fall down against the action of the return spring 25. The descent of the tab 15 frees the finger 14 which is then pushed back into the lower opening position by the spring 14a so that the valve 13 opens and the gas can flow towards the burner 3 Temporarily continuing the lowering movement of the control knob 24 beyond the intermediate position to open. the plate 19 pushes by its lower flange 19b the pusher 17 of 1 piezoelectric igniter 18. which then causes the production of a spark to! electrode 8 to turn on the gas After releasing the control knob 24, it is automatically replaced by the action of the return spring 25 in the intermediate open position which is shown in FIG. 1. It is retained in this position because the pawl 28 is then locked. as well as Pst represents on In figure 1I Indeed during the downward movement of the plate 21 d valve actuation 13. the upper branch 28a of the pawl 28 slides on the inner face 33h of the flap 33 and when it arrives just below bottom edge 33n of

2638 6 1 6

  this pawl 28 pivots clockwise about its axis 29 under the action of the spring 31 and 1 upper end of the upper branch 28n of the pawl 28 engages under the lower edge 33a of the flap 33 being thus immobilized by the latter. The key 28 being thus locked its lower branch 28b constitutes a fixed stop against which is applied the upper lug 19d of the plate 19 which prevents the automatic return of the two plates 19 and 21 in the closed position The skier can however cut to any time heating. by pulling the control knob 24 upward In this case the tab 19d forces on the pawl 28 and rotates it counterclockwise about 1 axis 29 thus disengaging the upper branch 28b of the edge 33a of the flap 33 From this moment the two plates 19.21 can automatically slide upwards under the action of the return spring 25 to switch to

  closing position of 1 gas supply.

  From the above description it can be seen that for

  that the pawl 28 can be locked in position and constitute a stop for holding the plates 19 and 21 in the open position of the gas it is necessary that the flap 33 is pressed inside the rod 12. otherwisethat the cables 32 are 12. Therefore, if the skier forgets to cut the heater beforehand when he opens the upper of his shoe the pure neck of the gas supply of the burner 3 is carried out automatically. Indeed the blocking flap 33 which is then

  pushed back to 1 outside as soon as the cables 32 are des-

  tightened under 1 action of its return spring 34. occupies the position shown in Figure 3 in which its inner face 33b is flush with the inner face dre the rear wall of the rod 12 Therefore if the positive dis 16 command 1 of the gas supply had previously been in the open position in which it was retained by the pawl 28 in abutment against the lower edge 33a of the flap 33 the pawl 28 then escapes h the abutment that constitutes the lower edge 33a of the flap 33 this

  which allows the two plates 19 21 to slide automntically upwards under the action of the return spring 25 for

  go to the closed position of] power supply in gnz.

  In the variant embodiment shown in FIGS. 4 and 5, the boot is of the front entry type, and the tightening of the boot shank 12 is produced by means of a cable 36 surrounding the upper part of the boot and which is attached to a boot. pivoting lever 37 provided with several hooks 38 to obtain various degrees of clamping The clamping lever 37 is nrticulé around an axis 39 on an outer clevis 41 which can slide horizontally relative to the wall of the rod 12. L hime A rivet 42 passes through a horizontal slot 43 formed in the fork 41 by a rivet 42 formed in the wall of the rod 12. The rivet 42 is fixed. In the interior of the shaft 12 there is a front end of a support bracelet 44 which extends along the inner face of the shaft 12 '. This support bracelet 44 includes a rear portion 44a which extends beyond the ratchet 28 of the device 16 for controlling the gas supply at this point the rear wall of the rod 12 forms a bead 45 projecting towards the outside and delimits an internal groove 46 whose tranversnal section corresponds to that of the wristband 44. Finally, the rear strap 44a of this bracelet 44 can be slipped into the groove 46. The support bracelet 44 is normally biased towards the rear by a compression spring 47. This spring 47 is housed in a horizontal lumen 48 formed in the front portion of the support bracelet 44 and is supported. at its anterior extremity. on a shoulder 49 protruding into the lumen 48 and from the wall of the rod 12. The spring 47 is supported at its rear end. on the posterior edge of the light 48 When the upper 12 of the boot is tightened on the lower leg of the skier. the crimping lever 37 is applied against the rod 12 as shown in FIG. 5 and in this position its transducer 41 is offset forwards. The forward movement of this clevis 31 is transmitted. by the rivet 42 h the rxtrme front portion of the Support bracelet 44 which is found to be drawn. The rear portion 44e of the support strap 44 is then pulled out of the groove 46 and in this extended position it is located just in front of it against the action of the spring 47. above one end of the upper branch 28b of the pawl 28 to provide a stop allows both the locking of the gas control device 16 gas supply in the open position. as in the cns of the embodiment described above with reference to Figures 1 to 3 If the heater is in operation. the skier loosens his rod 12 forgetting to cut off a gas supply, the loosening of the rod 12. by passage of the lever 37 in the position shown in phantom in Figure 5 causes the release of the support bracelet 44. This bracelet 44 is then pushed back to I under the action of the spring 47 this displacement is rnndu

  possible by the sliding of the rivet 42 in the light 43.

  Due to this movement towards the nrribre the rear part 44a of the support bracelet 44 is retracted into the groove 46 provided in the wall of the rod 12 and due to the deletion of the stop that it constitutes the pawl 28 is released and the plate 21 can then slide upwards in

  closing, by its lug 15 the supply valve 13.
