ABSTRACT:
A device for preventing inadvertent pressing of push button keys of an article, including an upper cover means, a turning axle means, and a pivot joint means. When an upper cover plate of the upper cover means is lifted, pointed portions of two curved projections of a relay axle of the turning axle means will displace along end recesses to pointed portions of two curved ends, so that the relay axle presses a retractable spring and displace radially in a transverse direction, so that its end wings extend into a wing chamber while two side wings extend into an end chamber. When the pointed portions of the two curved projections pass over the pointed portions of the two curved ends, since the pointed portions of the curved projections lose support thereof, they turn axially along the end recesses by means of the resilience of the spring until being positioned. Hence, the upper cover plate can automatically be uplifted about a certain angle to facilitate pressing of the push button keys.
