ABSTRACT:
An item of wearing apparel for receiving an extremity, such as a ski shoe or boot for receiving a foot, provided with an energy source supplying an energy consuming device, such as a heating device, and a device controlling a supply element of the energy consuming device connected between the energy source and the consumer device. The shoe or boot includes a device for detecting the presence of a foot within the boot so as to allow the opening of the energy supplying element alone when the boot is put on and to automatically cause the closing of this supply element as soon as the boot is removed. The energy consuming device incorporated in the boot can be a heating device of the electric type in which case the device for detecting the presence of the foot in the boot acts on an electric switch connected, between an electric energy source and a heating assembly with heat resistance, or even the type using liquid or gaseous fuel and in this case, the device for detecting the presence of the foot in the boot acting on a device controlling a valve connected between a gas or liquid fuel tank and a heating assembly. Preferably, the device for detecting the presence of the foot in the boot are sensitive to the pressure exerted by the foot on the internal sole of the boot and this detection of the pressure is transmitted mechanically to the device controlling the element for supplying the heating assembly with energy. The boot with an upper according to the invention which can be an alpine or cross-country ski shoe or boot is provided with a heating device which, in the case of the non-limiting embodiment presently described, is of the gas fuel type. However, the invention could be applied in the same manner to a boot provided with an electric or liquid fuel heating device.
