Description
FIELD OF THE INVENTION
[0001] The present invention relates to an operation wand for
curtains and the wand is connected to a transverse bar at a lower
end of the curtain and can be horizontally positioned.
BACKGROUND OF THE INVENTION
[0002] A conventional curtain assembly 5 includes a driving
mechanism 51 located at a top of the curtain and a lift cord is
connected with the driving mechanism 51 and hangs on one side of
the curtain 50. The user pulls the lift cord 52 to lift the curtain
to a desired height. The lift cord 52 just hangs on one side of the
curtain 50 so that it swings and hits the wall by wind to generate
frequent noise.
[0003] The present invention intends to provide an operation wand
assembly which is pivotably connected to a transverse bar connected
to the lower end of the curtain so as to lift or lower the curtain
by pushing or pulling the operation wand. The operation wand can be
positioned horizontally and does not affect by wind.
SUMMARY OF THE INVENTION
[0004] The present invention relates to an operation wand assembly
for curtains and comprises a transverse bar connected to a lower
end of the curtain and two end members are connected to two ends of
the transverse bar. One of the end members includes a hook
extending therefrom. An operation wand has an end pivotably
connected to the transverse bar and can be removably positioned in
the hook.
[0005] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a perspective view to show the operation wand
connected to the transverse bar of the curtain of the present
invention;
[0007] FIG. 2 is an exploded view to show the operation wand
assembly of the present invention;
[0008] FIG. 3 is a cross sectional view to show the two end members
connected to the transverse bar;
[0009] FIG. 4 shows that the operation wand is positioned
horizontally in the hook;
[0010] FIG. 5 shows the curtain is lifted to a higher position,
and
[0011] FIG. 6 shows a conventional curtain with lift cord.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Referring to FIGS. 1 to 3, the operation wand assembly for
curtains of the present invention comprises a transverse bar 1
connected to a lower end of the curtain 10 and the transverse bar 1
is a hollow tube with two open ends. Two end members 13 each
include an insertion 132 extending from an end plate 131. The
insertions 132 are inserted into the two open ends of the
transverse bar 1 and each of the insertions 132 includes a slot
1321 defined axially therein so as to define two parts which are
pushed inward to narrow the slot 1321 when inserting into the two
open ends of the transverse bar 1, the two parts generate an
outward force to contact against the inner wall of the transverse
bar 10. A protrusion 1322 extends radially from one of the two
parts of each of the insertions 132 and each of the protrusions
1322 includes an inclined surface 1323 defined in a distal end
thereof. The transverse bar 1 includes two holes 11 defined through
a wall thereof and the two protrusions 1322 extend through the two
holes 11 to position the end members 13. The user may easily push
the protrusions 1322 inward to remove the end members 13 out from
the two open ends of the transverse bar 1. One of the end members
13 includes a hook 4 extending therefrom.
[0013] A sleeve 31 has a polygonal inner surface which is mounted
to the transverse bar 1 which has a polygonal outer surface, a
C-shaped member 32 has two ends thereof connected to two ends of
the sleeve 31. An operation wand 2 has through hole 21 defined
through an end thereof and a ring 22 is connected to the through
hole 21. The C-shaped member 32 extends through the ring 22 such
that the operation wand 2 can be freely pivoted. Two collars 12 are
mounted to the transverse bar 1 and two cords connected between the
collars 12 and a fixed top case on a top end of the curtain 10. The
cords ensure the transverse bar 1 to be positioned
horizontally.
[0014] As shown in FIG. 4, the operation wand 2 can be removably
positioned in the hook 4 horizontally when not use. The horizontal
position also reduces the affection by wind to the operation wand
2. Referring to FIG. 5, the user can conveniently push the
operation wand 2 to lift the curtain 10 or pull the operation wand
2 to lower the curtain 10. Because the operation wand 2 is located
at the lower end of the curtain 10 so that even a short user can
access the operation wand 2.
[0015] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
