Abstract: A magnet catcher is used in closing and opening of a door of an audio rack and other cabinets and includes a magnetic stop member mounted on a door. A frame-mounted casing supports a movable member which magnetically retains the stop member when in contact with it. The casing includes a guide recess for guiding a yolk portion of the movable member to permit tilting of the yolk portion. A spring biases the movable member to a position outward of the casing. A rod fixed to the casing has an end guided by the movable member, so as to cause the yolk portion of the movable member to tilt when the door is being opened due to movement of the rod relative to the movable member. As the yolk portion tilts, the magnetic contact area is greatly reduced, and separation of the yolk portion from the stop member is facilitated.

Abstract: A retractable door structure for a storage case including a pair of guide grooves formed from the front end to the back end of the inner surfaces of the case panel, sliding blocks connected to each other by a connecting rod provided in the guide grooves, and a pinion mounted in each of the sliding blocks which is designed to engage with a rack formed in the guide grooves. The door is pivotally held between the sliding blocks by rotary shafts attached to the corners of the door. By means of this structure, the door can be slid inside the case after it is opened and the door is easily pushed in and pulled out of the case since the sliding blocks holding the door slide smoothly in the guide grooves.
