Publication number: 20160193488Abstract: A curtain is wound on a roller (2), provided in a head box (4), mounted in a ceiling (6). The curtain is also provided with a bottom bar (10). When the curtain is drawn up onto the roller, the bottom bar (10) can be used to close the head box (4). When deployed the bottom bar provides stability to the descending curtain, and in full deployment rests on the floor. The curtain is provided with additional strips (30) of fabric, to allow ease of roll up onto the roller. The strip(s) arc attached at their top end only, to the curtain. Typically this will be by sewing (32), but also may be rivets or other form of heat resistant connection. The strip(s) are also connected to the bottom bar. A cable (34) is attached to the strip(s), usually through a rivet, but any other form of secure attachment may be used. The cable is then connected to the bottom bar, via a spring (36). This connects to keep the strip(s) in tension, to enable ease of rolling of the curtain.Type: ApplicationFiled: March 5, 2014Publication date: July 7, 2016Applicant: COOPERS FIRE LIMITEDInventor: Andrew Cooper

Publication number: 20090310264Abstract: A fire or smoke barrier 1 has a curtain 2 deployed from a motorised roller 3 mounted in a head box 4. Remote from the head box and connected to the motor via a cable 5 is a motor controller circuit 6. A short circuit protection circuit 9 is connected to the motor within the roller at the motor end of the cable 5. On the motor side of the circuit 9 is a retarder circuit 10 connected across the motor terminals. The short circuit circuit comprises a pair of relays 11, 12, arranged with their normally open contacts 111,121 arranged in parallel. A drive voltage one 11 of the relays has its winding 112 across the input lines 14 of the circuit and the emf one 12 of the relays has its winding 122 across the output lines 15 of the circuit. The input lines 14 are connected to the cable lines 51,52 and the output lines 15 are connected to the motor terminals 16, via the retarder 10.Type: ApplicationFiled: June 12, 2009Publication date: December 17, 2009Applicant: Coopers Fire LimitedInventors: Andrew Paul Cooper, Victoria Louise Ford
