Innovative mechanical system for opening iron security bars in emergencies

Abstract

A mechanical system designed to open iron security bars fixed on windows during emergencies. The system operates through two activation methods: manual and automatic, ensuring rapid escape during fires. It includes a heat-sensitive mechanism that automatically triggers the opening without the need for external power sources. This innovation complies with international fire safety standards and is suitable for retrofitting existing windows or installing in new ones across various building types.

Description

[0001] Innovative Mechanical System for Opening Iron Security Bars in Emergencies

[0002] 1. Detailed Description:

[0003] The invention is a mechanical system designed to quickly and safely open iron security bars fixed on windows during emergencies. The system operates through either manual or automatic activation, ensuring ease of escape without requiring external power sources such as electricity or electromagnetic systems. It automatically activates when exposed to high heat from flames, causing the security bars to open in case of fire.

[0004] 2, The system consists of:

[0005] A metal chassis containing:

[0006] Two internal tension springs (hidden from view).

[0007] A metal wire enclosed within metal pipes, designed according to the required dimensions.

[0008] Two side hinges reinforced with push springs.

[0009] A metal handle connected to the wire, which pulls the springs to release the security bars. The handle can:

[0010] Be left without a lock for manual activation.

[0011] Or include a numbered lock that must be removed before opening.

[0012] Additional Components:

[0013] An emergency box:

[0014] Operates mechanically and automatically when exposed to fire.

[0015] Contains a heat-sensitive combustible element connected to the wire, which releases the security bars without human intervention. A specialized mechanism:

[0016] Includes a metal balance pin attached on one side to the wire (connected to the bars) and on the other side to a combustible rubber strip that retracts the tension spring when burned.

[0017] Operation Mechanism:

[0018] The security bars can be opened through two methods:

[0019] 1. Manual activation using the handle or emergency button.

[0020] 2. Automatic activation when exposed to heat from flames.

[0026] 6. Additional Notes:

[0027] This innovation complies with the recommendations of the National Fire Protection Association (NFPA), providing additional safety for buildings, and is a pioneering solution that meets the Saudi Building Code requirements, Section 310.4 (1101). Additionally, this system aids civil defense teams in accessing burning buildings quickly and effortlessly, eliminating the need to cut security bars with rescue saws or electric saws, thus saving precious time and enhancing the effectiveness of rescue operations.

Claims
