Pleated blind having positioning function
Abstract
A pleated blind includes a blind body having a plurality of
pleated portions each having a pleated edge, and a limit cord
secured to the pleated edges of the pleated portions of the blind
body. When the pleated portions are moved, the maximum distance
between any two adjacent pleated edges of the pleated portions is
limited by the limit cord, so that the open distance of each of the
pleated portions is limited by the limit cord to reach a determined
value. Thus, each of the pleated portions will not be opened
excessively due to improper operation by a user, thereby preventing
either one of the pleated portions from being deformed or distorted
due to an overload so as to enhance the outer appearance of the
pleated blind.

DETAILED DESCRIPTION OF THE INVENTION
[0019] Referring to the drawings and initially to FIG. 1, a pleated
blind in accordance with the preferred embodiment of the present
invention comprises a headrail 4, a blind body 1 mounted on the
headrail 4 and having a plurality of pleated portions 11 each
having a pleated edge 111, a lift cord 3 extended through the
headrail 4 and each of the pleated portions 11 of the blind body 1
to control upward and downward movement of the blind body 1, and a
limit cord 2 secured to the pleated edges 111 of some of the
pleated portions 11 of the blind body 1 to limit a distance between
the pleated edges 111 of the pleated portions 11 of the blind body
1.
[0020] Preferably, the limit cord 2 is secured to the pleated edge
111 of each of the pleated portions 11 of the blind body 1 to limit
a distance between any two adjacent pleated edges 111 of the
pleated portions 11 of the blind body 1.
[0021] In addition, the pleated edge 111 of an uppermost one of the
pleated portions 11 of the blind body 1 is attached to the headrail
4 by the limit cord 2.
[0022] When in use, when the pleated portions 11 of the blind body
1 are moved upward and downward by operation of the lift cord 3,
the maximum distance between any two adjacent pleated edges 111 of
the pleated portions 111 of the blind body 1 is limited by the
limit cord 2, so that the open distance of each of the pleated
portions 11 of the blind body 1 is limited by the limit cord 2 to
reach a determined value.
[0023] Thus, each of the pleated portions 11 of the blind body 1
will not be opened excessively due to improper operation of the
lift cord 3 by a user, thereby preventing either one of the pleated
portions 11 of the blind body 1 from being deformed or distorted
due to an overload.
[0024] As shown in FIG. 1, the pleated edge 111 of each of the
pleated portions 11 of the blind body 1 is serially attached to the
limit cord 2, and the pleated edges 111 of the pleated portions 11
of the blind body 1 are equally spaced from each other by
restriction of the limit cord 2.
[0025] As shown in FIG. 1A, the pleated edge 111 of each of the
pleated portions 11 of the blind body 1 is attached to the limit
cord 2 by sewing.
[0026] As shown in FIG. 1B, the pleated edge 111 of each of the
pleated portions 11 of the blind body 1 is attached to the limit
cord 2 by a high frequency melting process.
[0027] Alternatively, the pleated edge 111 of each of the pleated
portions 11 of the blind body 1 is attached to the limit cord 2 by
an adhesive.
[0028] As shown in FIG. 2, the blind body 1 is supported by a
molding die 5 to facilitate the high frequency melting process of
the pleated edge 111 of each of the pleated portions 11 of the
blind body 1.
[0029] As shown in FIG. 3, the pleated edge 111 of each of the
pleated portions 11 of the blind body 1 is serially attached to the
limit cord 2, and the pleated edges 111 of the pleated portions 11
of the blind body 1 are spaced from each other with different
distances by restriction of the limit cord 2, so that the pleated
portions 11 of the blind body 1 have different pleated angles.
[0030] In addition, the limit cord 2 is serially secured to the
pleated edge 111 of each of the pleated portions 11 of the blind
body 1 in a multi-state manner.
[0031] As shown in FIG. 4, the limit cord 2 is extended into a side
of each of the pleated portions 11 of the blind body 1 to reinforce
the strength between the limit cord 2 and the pleated edge 111 of
each of the pleated portions 11 of the blind body 1.
[0032] As shown in FIG. 5, the pleated portions 11 of the blind
body 1 are divided into several intervals 112 each having a single
pleated edge 111 serially attached to the limit cord 2. The
intervals 112 of the blind body 1 are equally spaced from each
other by restriction of the limit cord 2, and the open distance of
each of the pleated portions 11 in each of the intervals 112 of the
blind body 1 is limited by the limit cord 2 to reach a determined
value.
[0033] Accordingly, when the pleated portions 11 of the blind body
1 are moved upward and downward by operation of the lift cord 3,
the maximum distance between any two adjacent pleated edges 111 of
the pleated portions 11 of the blind body 1 is limited by the limit
cord 2, so that the open distance of each of the pleated portions
11 of the blind body 1 is limited by the limit cord 2 to reach a
determined value. In addition, each of the pleated portions 11 of
the blind body 1 will not be opened excessively due to improper
operation of the lift cord 3 by a user, thereby preventing either
one of the pleated portions 11 of the blind body 1 from being
deformed or distorted due to an overload so as to enhance the outer
appearance of the pleated blind. Further, the limit cord 2 is made
easily and has an inexpensive price, thereby greatly decreasing
cost of fabrication.
[0034] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
