Abstract

Door security chain 11 primarily for UPVC doors. A support 4 secured to a wall supports the chain 11 and an alarm 6. The chain has a ring 12 to engage over a door handle and a link 10 attaches to a fixed eye bolt 9 to limit door opening. If the door is forced open then link 10 breaks and allows the chain to pull an alarm activation pin 14. The arrangement does not require holes to be drilled in the door or frame.

Claims (1)

  1. This concept is primarily designed for UPVC doors, although can be
    fitted to any door where the occupant has concern about their safety. Presently door security chains in the main are fitted to wooden doors and are not advised to be fitted to UPVC doors as the screws or bofts can interfere with the locking mechanism, LJPVC doors in the main are quite a flimsy plastic shell and will not support adequately screws or bolts.
