发明名称 Arrangement for safe anchoring of a letter receptor
摘要 Arrangement at a letter receptor, which consists of a housing (12) which is attachable as a whole to a door (10) or similarly opened hole. At the housing (12) at least one flap (14, 16) is stored to cover the opening of the letter receptor housing (12), which later is fastened to the door or similar by screws. At that section (30) of the door (10) which holds the screws a perforated plate (32) is arranged with tightly positioned holes (34) that are so positioned in the screw's insertion direction that the screw's (22) threading when fastening to the house (12) intrudes into one of the plate's (32) holes (34). In this way a safe anchorage of the screw (22) in the door's material (30) via the plate (32) is achieved.<IMAGE>
