FIELD: equipment used as individual safe. SUBSTANCE: sectional cabinet is mounted on carcass poles with guiding slots for receiving metal shutter movable along slots in vertical plane and adapted for closing safe door opening. Shutter is composed of U-shaped metal links engaged one with another and is loaded with counterweight. Shutter is suspended on driven rotary cylindrical support and is provided with handle and spring-loaded retainer having limiter. Cylindrical support has two disks tangentially adjoining to vertical slots of carcass and mounted on pin within carcass. Cam restrictors for end retainers fastened in guiding slots of door opening are made in the form of horizontal sliders kinematically coupled with shutter locking mechanism. Handle is fixed on lower link of shutter-type door loaded with extension spring. Resilient stops are positioned above handle on door opening cross-piece. Shutter link end bending angle depends on thickness, width, height and radius of supporting disk. Construction allows shutter-type door to be manually opened by vertical displacement along slots, automatically locked and self-adjusted. EFFECT: enhanced reliability in operation, compact construction combined with spaciousness. 2 cl, 4 dwg
