English 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.


Claims

Note: Claims are shown in the official language in which they were submitted.


CLAIMS
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.

CA 02510409 2005-06-03
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.
