ABSTRACT:
An improved tilting device for an umbrella includes an elongate connecting member connected to a control block, an upper bending head connected to an upper rod, and a lower bending head connected to a lower rod. The elongate connecting member has a pivot hole at the lower end. The upper bending head has a pair of downward extending plates each having a pinhole and an inclined slot. A spring member is mounted around the control block and the elongate connecting member. Each lateral side of the lower bending head is formed with a pinhole and an obtuse angular-shaped guide slot. The upper bending head is connected to the lower bending head and fixed in position by a pin. The lower end of the elongate connecting member is connected to the combination of the upper and lower bending head by a displacing pin extending through the guide slots, the inclined slots and the pivot hole. The upper and lower rods of the umbrella are connected and tiltable by the tilting device when a pull cord is pulled via three guide wheels to cause a runner to move upwards upon rotation of a crank handle; when the handle is further rotated, the control block is lowered along the upper rod and in the meantime, the connecting member together with the displacing pin moves along the guide slots of the lower bending head hence making the upper bending head to rotate about the pin.
