Apparatus for producing cold principally for the application of cold by contact on the body of living beings

Claim 1

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, constituted by a very small, light apparatus which is easy to take hold of and easy to handle in one hand, comprising a body carrying a very small generator rapidly generating cold within the temperature range of -10°C to -80°C, the surface of application of cold by contact being constituted by the actual surface of the generating element or by an auxiliary surface which is thermally connected to the latter, the cold generating element comprising at least one thermoelement having a Peltier effect and the apparatus also carries means for cooling the hot face of the thermoelement and means for supplying electric current to the generating element including means for connecting and disconnecting said supply of current said apparatus further including a device which acts as a support for the apparatus and which ensures the recharging of the battery through a circuit which is closed by the mere fact that the apparatus is mounted on the support.

Claim 2

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, constituted by a very small, light apparatus which is easy to take hold of and easy to handle in one hand, comprising a body carrying a very small generator rapidly generating cold within the temperature range of -10°C to -80°C, the surface of application of cold by contact being constituted by the actual surface of the generating element or by an auxiliary surface which is thermally connected to the latter, the cold generating element comprising at least one thermoelement having a Peltier effect and the apparatus also carries means for cooling the hot face of the thermoelement and means for supplying electric current to the generating element including means for connecting and disconnecting said supply of current said apparatus further including a device which acts as a support for the apparatus and which ensures the recharging of the battery through a circuit which is closed by the mere fact that the apparatus is mounted on the support.

Claim 3

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, constituted by a very small, light apparatus which is easy to take hold of and easy to handle in one hand, comprising a body carrying a very small generator rapidly generating cold within the temperature range of -10°C to -80°C, the surface of application of cold by contact being constituted by the actual surface of the generating element or by an auxiliary surface which is thermally connected to the latter, said apparatus being disposed inside a case provided with at least one access door and supplied with current by an electric battery provided with a switch, the cold generating element being disposed in the upper part of the case, and at least one thermoconductive plate being disposed in contact with the radiator of the cold generating element, said case being provided with a lid pivoted to the upper part of the case for pivotal movement between a raised position and a closed position, said lid being apertured in such a manner than when said lid is closed, the thermoconductive plate or plates extend through the apertures.

Claim 4

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, constituted by a very small, light apparatus which is easy to take hold of and easy to handle in one hand, comprising a body carrying a very small generator rapidly generating cold within the temperature range of -10°C to -80°C, the surface of application of cold by contact being constituted by the actual surface of the generating element or by an auxiliary surface which is thermally connected to the latter, said apparatus being disposed inside a case provided with at least one access door and supplied with current by an electric battery provided with a switch, the cold generating element being disposed in the upper part of the case, and at least one thermoconductive plate being disposed in contact with the radiator of the cold generating element, said case being provided with a lid pivoted to the upper part of the case for pivotal movement between a raised position and a closed position, said lid being apertured in such a manner than when said lid is closed, the thermoconductive plate or plates extend through the apertures.

Claim 7

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, comprising a body carrying a Peltier thermoelement having a cold face with a cold surface and a hot face, said Peltier element being mounted along the periphery of said body so that said cold surface of said Peltier element is spaced outwardly of all other parts of said body and is directly engageable with the body of the living being to thus apply cold directly thereto, and means for cooling said hot face comprising an air passage having an air inlet opening and an air outlet opening in said body, said passage being in communication with said hot face of said Peltier element, and fan means for moving air through said passage to cool said hot face of said Peltier element.

Claim 8

An apparatus for generating cold, principally for the application of cold by contact on the body of living beings, comprising a body carrying a Peltier thermoelement having a cold face with a cold surface and a hot face, said Peltier element being mounted along the periphery of said body so that said cold surface of said Peltier element is spaced outwardly of all other parts of said body and is directly engageable with the body of the living being to thus apply cold directly thereto, and means for cooling said hot face comprising an air passage having an air inlet opening and an air outlet opening in said body, said passage being in communication with said hot face of said Peltier element, and fan means for moving air through said passage to cool said hot face of said Peltier element.
