Lift rod apparatus for cordless shades
A lift rod apparatus for cordless shades includes a rod and an anchor plate. The rod has a upper end coupled with a latch member which has two opposing elongated ends and a holding bar spaced from the latch member. The anchor plate has a slot to be passed through by the latch member. The anchor plate can be installed on a cordless shade. The latch member can pass through the slot and be turned for a selected angle for coupling or removing. The rod has a selected length to aid users of not sufficient height to control rolling and extension of the cordless shade. Using of the cordless shade is more convenient.
The present invention relates to a lift rod apparatus for cordless shades and particularly to a lift rod apparatus to control rolling and extension of various types of cordless shades.
BACKGROUND OF THE INVENTION There are numerous types of window coverings on the market, such as blinds, bleated shades, roman shades and the likes. They are mainly installed on doors and windows of houses to block sunshine and be used as adornments. Depending on user's requirements, the general window shades can be divided in cord controlled shades that are rolled and extended through a lift cord and a cordless shade 10 as shown in
When in use for rolling or extending the cordless shade 10, first, user's hand grasps the lower rail 13 and pushes upwards. The control means can automatically retract the fabric shade 12 upward. To extend the cordless shade 10, the hand pulls the lower rail 13 downwards, and the control means can aid extending of the fabric shade. Thus there is no need to provide a lift cord for rolling and extending of the shade.
In practice, user has to grasp the lower rail 13 and exert a force on the fabric shade 12 to perform operation of rolling upwards or extending downward. For users who do not have enough height and cannot reach the lower rail 13 while the fabric shade 12 is lifted to a selected elevation, rolling operation of the shade is difficult. To pull the shade down for extension, users have to rely a chair or stool to reach and grasp the lower rail 13 on the bottom of the fabric shade 12. This creates a lot of troubles and inconveniences. There is still room for improvement.
SUMMARY OF THE INVENTIONTherefore the primary object of the present invention is to provide a lift cord apparatus for cordless shades that is adaptable to various types of cordless shades. It is installed on the bottom of the shades to aid users of not sufficient height to roll and extend the shades.
The lift cord apparatus for cordless shades according to the invention mainly includes a rod and an anchor plate. The rod has a latch member on a upper end. The latch member has two elongated ends and a holding bar on a lower side spaced from the latch member. The holding bar has an axial direction coinciding with the long side of the elongated ends of the latch member. The anchor plate has a coupling portion which has an extension on one side. The extension has a slot to be passed through by the latch member.
By means of the structure set forth above, the anchor plate can be coupled with a cordless shade. The latch member can pass through the slot of the anchor plate and be turned to a selected angle so that the rod and the anchor plate can be coupled or disengaged. With the rod formed in a selected length, it can aid users who do not have a sufficient height to control rolling and extension of the cordless shade. Operation is more convenient.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Please referring to
The rod 20 has a latch member 21 on a upper end that has two opposing elongated ends 211, and a holding bar 22 below the latch member 21 and spaced therefrom at a selected distance. The holding bar 22 has an axial direction coinciding with the long side of the elongated ends 211. The rod 20 further has a handle 23 on a lower side to be grasped by users.
The anchor plate 30 has a coupling portion 31 to couple with the lower rail 43 of the cordless shade 40. The coupling portion 31 has an extension 32 on one side with a slot 321 formed thereon corresponding to the latch member 21. The slot 321 has two opposing sides 321a mating the elongated ends 211 to allow the latch member 21 to pass through the slot 321.
As shown in the drawings, the coupling portion 31 further has a plate 311 with two opposing sides extended upwards to form two side walls 312. The inner sides of the side walls 312 are extended inwards to form flanges 313. The extension 32 is located on an outer side of one side wall 312. Referring to
