This can be a pivoting of the magnifying glass towards the user regardless of whether this holds the magnifying glass in his left or right hand on the handle can be achieved.
• the handle of the magnifying glass pot is shaped so that it touches the footprint with its free Griffend Scheme.
• the Griffend Scheme By resting the Griffend Schemees the handle a more comfortable operation of the magnifying glass can be achieved because any vibrations (starting from shaky hands) are less strongly transmitted to the "fixed" magnifying glass.
• the handle end of the am Lupen emotions arranged handle arranged rollable in the plane of the footprint or support. It means rollable that the Griffend Scheme is shaped so that it forms according to the pivoting over the entire pivoting movement at least one point of contact and / or contact line with the footprint.
• Another measure to achieve a secure state of the stand magnifying glass it is to support at least the edge region of another, pivoted Lupentopfteils on the footprint in at least one pivot position next to the lowermost Lupentopfteil.
• a pivot position can represent, for example, an end position.
• the stand magnifier has an operable with batteries or mains voltage bulb, it is advantageous to provide a charging socket for the introduction of a charging plug or power cord plug.
• This charging plug can be arranged, for example, at the free end of the handle and it is important to ensure that a charging plug inserted into this does not hinder the rolling movement of the handle end on the footprint during the pivoting of the stand magnifier. This is achieved, for example, in that the charging socket with its central longitudinal axis of the magnifier body directed in opposite directions and upwards (obliquely upwards).
