LockLatch™ – A clever South African latch invention with “world wide” protection through PCT Applications

August 3, 2016

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 Brazil, 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 on board 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 round, 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, Anthony holds the South African and international patent for LockLatch™, and a hi-tech engineering company manufactures high-quality LockLatches from C304 stainless steel aimed at helping homes, boats and motorhome stay ventilated without compromising on home security or home safety.

Much like the Kreepy Krauly and Pratley Putty, two famous South African inventions, LockLatch is a perfect example of how a simple idea, such as a latch,and a stroke of genius combine in a pressure cooker of necessity. Asked why everyone needs a LockLatch, Anthony says: “Safety! Unfortunately today we need to protect our homes and loved ones and I believe LockLatch is your first line of defense. 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.”

As the name indicates, LockLatch™ is simply a lockable latch that allows you to leave your windows or doors open but locked. Easily used as a window ventilation lock and door latch which can be help improve boat security, motorhome security and home safety while

There are 3 sizes available, all with adjustable gaps: MiniLatch allows an adjustable gap between 1.8 and 3.1 inches the LockLatch with an adjustable gap between 3.6 to 6.7 inches  and the PetLatch (the largest of the 3) with an adjustable gap between 5.7 and 9 inches. LockLatch is a true DIY home security product, is made from C304 stainless steel with a satin finish and fits all doors, sliding doors, windows and hatches horizontally and vertically. LockLatch is quality assured and comes with a lifetime guarantee. LockLatch prevents opportunistic theft and wind damage while providing fresh air, small pet access and peace of mind to protect your home.

In between yacht racing across the Atlantic, playing guitar and flying, Anthony is now living the life of a seasoned inventor in the seaside town of Knysna in South Africa. Anthony promises more inventions in the pipeline and we can’t wait.
