Have you ever used an umbrella more than a year? Every time when raining you have to buy an additional umbrella even though you bought a few days ago, and if that sums up in a year, the amount of them is enormous. The best way to keep your umbrella is to lock it. That’s how I come up with the Lockerella, combining handle and locker. There is a locker that you have to push a button to unlock it. I found a similarity between the button locker and the umbrella handle. Umbrella handle also has button to open the umbrella. That’s why I designed the Lockerella.
