UNIVERSAL WINDOW BLIND TRIMMER
This invention relates to a window blind trimmer and more specifically to a
universal
trimmer which is capable of trimming a wide variety of window blinds.
Window blinds are the most popular and economical means for dressing a window.
They
provide an ergonomical and pleasant covering for windows. Window blinds
commonly consist of
a plurality of horizontal slats mounted between a top head rail and a bottom
rail by a plurality of
vertical cords threaded through openings formed in the slats. Two of the cords
located adjacent to
the two sides of the blind commonly provide a pull cord adapted to a pulley
mechanism such that
they are operative for raising the slats and the bottom rail to bundle the
slats beneath and adjacent
to the top head rail so as to open the blind, or lowering the slats to
position evenly spaced from
one another horizontally over the window. The slats may also be turned
horizontally to either
close or open the spacing between them whereby to close or open respectively
the view through
the window. The slats are made in a variety of materials such as plastic,
wood, fabric, fiber
material, or metal. Similarly, the head rail and the bottom rail may also be
made in a variety of
plastic materials or metals.
Due to the variety of sizes of windows, window blinds are commonly produced in
several
standard sizes that conform with windows of some standard sizes. For non-
standard size
windows, a blind slightly larger then the window opening must be custom
trimmed by the vendor
or installer to fit the window. The vertical length of the blind is trimmed by
removing some of
the slats from a blind having a longer vertical length than the window
opening, while the width
of the blinds must be trimmed by cutting off two equal end portions of the
head rail, bottom rail
and slats from a width longer than the window opening so that the blind may
fit inside the
-1-

CA 02568273 2006-11-16
window opening. The head rail and the bottom rail are commonly trimmed by
inserting
individually their ends to be cut into a die provided on a support frame. The
die has an openings
in the shape and size of the cross sectional shape and size of the head rail
and bottom rail and a
shear is activated either pneumatically, electrically, or manually to cut off
the selected end
portions. The slats may then be bundled together with their ends inserted and
mounted firmly
into the trimmer such that the selected end portions may be trimmed off with
an electric rotary
saw or pneumatic shear which are also mounted on the support frame.
Due to the wide variety of shapes and sizes and materials of the head rail and
bottom rail
as well as the slats in the variety of window blinds, it is necessary for the
vendor such as a
building supply store to equip with a plurality of trimming machines with each
machine
dedicated for cutting a different variety of blind. This requires a
considerable amount of floor
space at the vendor for installing and operating the plurality of trimming
machines whereas
vendor's floor space is always at a minimum in order the maximum amount of
floor space may
be used to accommodate a maximum amount of merchandise.
It is a principal object of the present invention to provide a window blind
trimming
machine which is operative for trimming window blinds having head rails,
bottom rails and slats
of a wide variety of shapes and sizes and made of a wide variety of materials.
It is another object of the present invention to provide a window blind
trimming machine
which is simple in structure and requires very little space for installation.
It is another object of the present invention to provide a window blind
trimming machine
which is easy to operate.
It is yet another object of the present invention to provide a window blind
trimming
