Abstract
A pull out retractable system, such as a vertical blind, which pulls back on a spring system located in a metal core. The metal core has a twisted spring insert that is connected at both ends, and has twisted tension in the middle to allow the retractable motion after pull out. A
safety material is then wrapped around the spring system and is then placed in a casing made of aluminium for strength and support. For ease of movement, a slit is located at one side to allow the material to slide in and out.
The safety material is pulled out and stretched across an area and connected at the other end with hooks and magnets. To release, unhook and the material retracts back into the casing till next use.

Description
DESCRIPTION
Technical Field The invention relates generally to a pull down blind, with a spring tension bar which stores coiled energy. The coiled spring energy is released when the safety material is pulled out and is restored when the safety material is wrapped back up.
Background of the Invention Retractable blinds with a spring coiled bar have been on the market for years. In the common design of the coiled bar there is not enough tension for the material to be pulled out horizontally over an area over feet in length, so a heavier coiled bar is needed to ensure strength and durability.
Disclosure of the Invention Accordingly, an object of the present invention is to provide a new design for a safety barricade utilizing a spring tension bar.
Description of Drawings See attached drawings.

Claims (4)
1. A spring tension device for pull out and retracting.
2. The device, as defined in claim 1 has a spring tension core which allows material to pull out and retract, wrapping itself around the tension core.
3. The device, as defined in claim 2 is then put into and aluminium housing and fastened at the top and bottom to secure the spring tension core. The aluminium housing has a slit along one side so the safety material that is wrapped around the spring tension core can be pulled out and retracted horizontally.
4. The device as defined in Claim 2 where the safety material after being pulled horizontally then connected at the other end by hooks and magnets allowing a safety barricade to exist.
Retract the safety barricade by unhooking the safety material and the material retracts back in to the housing and is wrapped around the spring tension core.
Retract the safety barricade by unhooking the safety material and the material retracts back in to the housing and is wrapped around the spring tension core.
