They say that necessity is the mother of all invention and in the case of South African inventor, Anthony Bairos, this couldn’t be truer.

Some time ago while sailing along the North East Coast of Venezuela, Anthony frequently moored in marinas where he experienced a spate of burglaries and poor marine security as a result of keeping his yacht hatch open for ventilation when going ashore.

As Anthony lay annoyed on his bunk he dreamed up a lockable latch that would allow him to ventilate his yacht while protecting it from long fingers. This led to the birth of the very first LockLatch™, which was made onboard as part of his boat security system.

Back on SA shores, Anthony fell in love with a sausage dog called Toll-free. Less in love with having to get up every 5 minutes to let Toll-free out, he realized that the very same lockable latch that kept his yacht safe and ventilated could keep the door open whilst remaining locked. Ultimately making it an ideal pet door alternative. This time around, his unrefined version generated much interest from friends and family who were so impressed that Anthony knocked out a few proto-typish versions and asked them to try it out in order to confirm his need to apply for a patent.

Anthony never intentionally decided to become an inventor but kept improving his lockable latch invention. After coining the name LockLatch, Anthony knew he was onto a good thing. He sought out a pro to help him and found a bearded, bespectacled 85-year-old serial inventor who lived from his many inventions and was ready to mentor him. Showing Anthony the ropes and teaching him the discipline of how to turn his idea into a real marketable product included costing, market and materials, research, manufacturing systems and patenting – a process Anthony describes as long, arduous and enlightening.

Today, LockLatch [Pty] Ltd holds the South African and international patent for the LockLatch™ range, and they are manufactured by a hi-tech engineering firm in Howick, KwaZulu Natal, with each LockLatch produced helping homes, offices, hotels, institutions, boats and motorhomes stay ventilated without compromising on home security or home safety.

Apart from that, fresh air, especially along the coast, should be enjoyed and LockLatch allows you to keep your windows open for ventilation whilst also protecting it from the wind.”
