FIELD: umbrella for protection of person or group of persons from rain or solar rays, may be used for umbrella-type tents-advertisement carriers. ^ SUBSTANCE: umbrella has spokes for attachment of tent thereto and bushing with slot-type longitudinal cuts provided outside the bushing. Inner ends of spokes are freely inserted at the outside of bushing into its slot-type cuts so that ends of internal ends of spokes are always pressed within slot-type longitudinal cuts to bushing, when tent is open, and are retained within slot-type longitudinal cuts, when tent is closed, owing to tent tensile force. ^ EFFECT: simplified construction and improved accessibility for repair. ^ 6 dwg |
