Properties which face onto the street are often troubled by having bicycles, motorcycles, dogs and even protesters chained to their railings. This makes the place untidy, especially as some of these cables and chains are ultra-resistant to cutting and removal.
Today’s invention offers a new railing design which consists of a set of tapering metal ‘blades’ with rounded tops (these would actually be each shaped like half a French stick, split longitudinally and then hollowed out). They would protect people from falling into the basement below, or banging into the windows behind, but would also allow anything chained around them to be lifted clear and removed.
The tapering profile used makes leaving anything attached to these rails obviously insecure and liable to be ‘liberated’ by the building’s owner or any passing thief.
