A sportsboard locking apparatus for securing sportsboard from theft includes a simple, multiple element apparatus which engages elements of a standard sportsboard and further provides for a method by which the sportsboard may be secured to a stationary article avoiding theft. The apparatus operates simply with few moving parts and fits standard sportsboard designs. A cross bar is intimate to the sportsboard's body and located within a cylindrical cup which is recessed below the sportsboard's outer surface, the cross bar being securely fixed to the board's core structure. The apparatus incorporates a hooked element which surrounds the crossbar and a pin element which encloses the cross bar within a space formed between pin and hook element's engagement end. While the hook and pin elements enclose the cross bar below the sportsboard's outer surface, the apparatus's elements positioned above the sportsboard's outer surface insure firm, secure engagement between apparatus and sportsboard. Importantly, the apparatus elements above the outer surface of the sportsboard are free to rotate or spin independent of the hook element and about the pin element's axis without affecting the engagement between apparatus and sportsboard. The apparatus engaged sportsboard may be secured to a stationary article to prevent the sportsboard's unauthorized movement utilizing padlock and security cable elements.

An apparatus according to claim 13, wherein the controller further has a nonvolatile data storage unit and twenty-fourth control means which stores control data about the control that the controller has performed, into the nonvolatile data storage unit when the preset time for the twenty-third control means elapses. 15. An apparatus according to claim 13, wherein the controller has a twenty-fifth control means, which performs a pressure balance control to balance refrigerant pressures at high- and low-pressure sides of the refrigerating cycle during the preset time the twenty-third control means elapses. 16. An apparatus according to claim 13, wherein the controller further has a twenty-sixth control means, which lowers the output frequency of the switching circuit to a preset value when the power supply for the switching circuit is switched, in spite of the control performed by the twenty-second control means. 17. An apparatus according to claim 13, wherein the twenty-second control means controls the switching circuit in accordance with the temperature detected by the intra-chamber temperature sensor, controls the output voltage and output frequency of the switching circuit and switches a control pattern of the output voltage and output frequency in accordance with whether the power supply of the switching circuit is the generator, the commercial power supply or the storage battery unit, and the controller further has twenty-sixth control means and twenty-seventh control means, said twenty-sixth control means being designed to lower the output frequency of the switching circuit to a preset value when the power supply for the switching circuit is switched, in spite of the control performed by the twenty-second control means, and said twenty-seventh control means being designed to change the output voltage of the switching circuit so that the output frequency of the switching circuit may remains at the preset value when the twenty-sixth control means lowers the output frequency of the switching circuit, though the control pattern of the twenty-second control means is switched. 18. An apparatus according to claim 13, wherein the twenty-second control means renders the rate of changin
