Anti-ligature keyless access control device
An anti-ligature keyless access control device for securing a door comprising a keyless entry cylinder 14 with an electronic cylinder housing 18, a locking cam 22 for actuating locking devices, an electronics receiver module to verify authorisation of a person requesting access, and a rotatable knob 24, and an anti-ligature turn pull 26 and base 28 surrounding the rotatable knob 24 which resists or inhibits ligatures from being attached thereon. The anti-ligature turn pull may be a hemispherical handle with a series of equidistant finger grip recesses 36, preferably in the shape of a tear drop. There may be an extending lip 42 on the base 28 which overlaps the edge of the turn pull 30 creating a continuous surface. The base may overly the outer cover 12 of the locking device. Various manufacturing methods are disclosed such as forms of moulding, 3D printing, and various plastics materials such as polypropylene, which may include an antimicrobial additive and may be coloured. The device may be used in mental health treatment settings or residential care homes and may be retrofitted to existing lock sets.
