Hinge // 2549591

FIELD: construction.

SUBSTANCE: at door opening, flap 4 with bush 1 and ring 6 turns about pin 3. It results in sliding of solid of revolution 10 from locking surface 9 into groove 8 that does not impedes free revolution of bush 1. After opening, door activated by return spring starts closing at turning the flap 4 with bush 1 and ring 6 about pin 3 in reverse direction. Note here that solid of revolution 10 gets onto locking surface 9 to impede door closure. Torque developed by return spring drives solid of revolution 10 over locking surface of resilient beam 7 to strain the latter. Thereafter, solid of revolution starts turning to pass ring 6 with bush 1 relative to pin 3 so that braking moment is developed. Said door presses tightly without noise and against box surface.

EFFECT: simplified design, higher reliability and ease of use.
