Abstract
A display frame for changing of multiple pictures used as a picture frame or an advertisement billboard, it comprises in an assembly of a framework, multiple pictures, a grating plate and a movably mounted motor; the pictures and the grating plate are assembled in the framework, a leaf of specific shape is driven by the motor to change the positions or angular positions of a picture sheet or the grating plate, thereby effects that the pictures on the grating plate are automatically changed and entirely presented in prolonged times are achieved.
Claims20
A display frame for changing of multiple pictures, said display frame at least comprises in an assembly a framework, a picture sheet, a grating plate and a movably mounted motor;
- said picture sheet includes therein at least two pictures, said picture sheet and the grating plate are assembled in said framework, a leaf of specific fan shape is driven by said motor to change positions or angular positions of said picture sheet and said grating plate, thereby said pictures of said picture sheet on said grating plate are adapted to automatically changing and entirely presenting in prolonged times;
- said display frame is characterized in that:
- said specific fan shaped leaf is composed of two or more than two semicircles of different radii or non semicircular shapes all with same center, when a rotating axle of said motor drives said specific fan shaped leaf to rotate, lengths of arcs of said specific fan shaped leaf of different radii change positions or angular positions of said grating plate, thereby effects that said pictures on said grating plate are alternately changed and entirely presented in prolonged times are achieved.
