| 摘要 | A disposable umbrella includes a staff having an upper end and a lower end suitable for gripping by a user. A fixed collar is mounted on the upper end of the staff. A plurality of main struts are pivotably attached to the fixed collar and extend radially from the fixed collar. The main struts are movable from collapsed positions, wherein the main struts extend generally parallel to the staff, to open positions, wherein the main struts extend outwardly from the staff. A waterproof film is fixed to the main struts, such as by adhesive, and extends generally from the staff to the extended ends of the main struts. A slidable collar has a bore therethrough and is slidably mounted for movement along the staff. A plurality of actuating struts are provided, the actuating struts having an inner ends pivotably attached to the slidable collar and outers end pivotably attached to associated main struts so that movement of the collar along the staff towards the upper end of the staff causes the main struts to move out to their open positions. A latch is provided for selectively holding the slidable collar in a predetermined position on the staff to thereby hold the main struts in the open position, or releasing the slidable collar to allow movement of the slidable collar towards the lower end. The staff, collars, struts, waterproof film and latch are all formed of bio-degradable materials. In this way the umbrella may be disposed of without harming the environment. | ||||||
