of a Blind and the Types Available
you decide if you want to have blinds,
let’s look at what a blind actually is and it’s
origins. The window
blind is a specific type of window covering which is made
with slats of fabric, wood, plastic or metal that adjust by
rotating from an open position to a closed position by allowing
slats to overlap. Metal window blinds are often used outside
of the house or business to protect against theft, temperature,
vision, bad weather and fire. Often external blinds are machine-operated,
rather than hand operated.
The horizontal version uses a thin woven "ladder"
system to suspend the slats and enable slats to be closed
via a rotating drum to which each upper end of the woven ladder
is wrapped and attached. A lift cord allows the blind to be
pulled up and stack tightly to top of window when desired.
Quite simple but very effective!
Of course, you also have the vertical
blind which uses a generally wider slat and has the added
feature of being able to pull a cord to stack the slats together
either to one side or to separate in the centre and stack
on each end. This design of blind
allows rotation of slats by a rotating shaft in the upper
head rail housing which runs through independent geared carriers
that will convert twisting of tilt rail to a rotation of each
individual slat in synchrony. The original vertical blinds
were invented in the United States, in fact, Kansas City,
Missouri, by Edward Bopp and Fredrick Bopp who held the original
patent. The company name at the time was Sun Vertical. In
the 1960s the patent and company was sold.
Finally, the term window
blinds is also sometimes used, somewhat inaccurately,
to describe window coverings generically—in this context
window blinds include almost every type of window covering,
i.e. shutters, roller blinds, roman blinds and of course,
and horizontal blinds.
In summary, you can see there are a lot of choices and may
be a few more than you had thought of.
