A ~ur~larproof And Wind/Rain Resistant
Assembled Blind
Background of the Invention
Conventional vertical type of blind is composed of
thin slats which are hung on a hook member mounted on a
wheel seat disposed in an upper beam, whereby an
adjusting means installed in the upper beam can be used
to collect, stretch and orientate the slats.
Such simple structure can only provide sun-shading
function while failing to resist wind or rain 30 that it
is apt to be swung by the wind to collide the window and
the dust and rain will aIl enter the house. Moreover,
such collision often cause the damage of the slats and
the window. ~herefore, such blind is unsatisfactory to
the user.
SummarL of the Invention
It is therefore a primary object of this invention
to provide a burglarproof and wind/rain-resistant
assembled blind which can effectively insolate the wind
and rain.
It is a further object of this invention to
provide the above a~smebled blind which can be
extensively adjusted and can be assembled by the user.
~a ~t..~s
According to the above ohjects, the pre~ent
invention includes a fixed guide rail two sides of which
are respectively disposed with dove-tail rails, and arch
support bases formed with corresponding dove-tail lugs.
Ihe support bases are fitted on the fixed guide rail
side by side and a bearing is formed on the support base
for a lower connector of a slat to inAert therein. A
shaft rod of a connector extends downward to engage wlth
a gear meshing with an inner coil rod of the support
base, whereby an adjusting rod can be rotated to adjust
the angle of the slats, two ends of the support base are
formed with an outer step and an inner step the width of
which is equal to that of L-shaped flaps disposed on two
sides of each slat. Ihe width of the inner and outer
steps and the flaps is adjustable to suit various
dimensions of different windows.
