The present invention relates to an attachable lifter rod apparatus with blind or shade material holder for cordless blinds and shades, and particularly to a lifter rod apparatus to control and extend various types of cordless blinds and shades.
Therefore the primary objective of the present invention is to provide a lifter rod apparatus with blind or shade material holder for cordless blinds or shades that is adaptable to various types of cordless blinds or shades. It is installed on the bottom of the blinds or shades to aid users of not sufficient height to extend and roll the blinds and shades.
The lifter rod apparatus for a cordless blind or shade according to the invention mainly includes two opposing mechanical apparatuses identical in shape and size. Each apparatus consists of a blind or shade material holder which has a dual function as an anchoring plate for the lifter rod, rod hinge, hinge spring pin and rod holder clip to be installed on a cordless blind or shade to the blind or shade's bottom rail.
By means of the structure set forth above, the blind or shade material holder anchoring plate can be coupled with the bottom of the bottom rail of the cordless blind or shade with fastening devices selected from the group consisting of glue, tape and screws. With the blind or shade raised to allow the lifter rods to extend vertically, it then can aid users who do not have sufficient height to control rolling and extension of the cordless blind or shade. When the blind is extended downward, the lifter rods can be collapsed and clipped horizontally under the bottom rail to store and allow the blind or shade to fully extend downward. 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.
There are numerous types of window coverings on the market, such as blinds, pleated shades, roman shades and the like. 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 into cord controlled shades that are rolled and extended through a lift cord and the cordless blind or shade 10 as shown in
When in use for rolling or extending the cordless blind or shade 10, first, user's hands grasp the lower rail 13 and push upwards. The control means can automatically retract the blind or shade 12 upward. To extend the cordless blind or shade 10, the hands pull the lower rail 13 downwards, and the control means can aid extending of the blind or shade. Thus there is no need to provide a lift cord for rolling and extending of the blind or shade.
In practice, user has to grasp the lower rail 13 and exert a force on the blind or 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 blind or shade 12 is lifted to a selected elevation, rolling operation of the blind or shade is difficult. To pull the blind or shade down for extension, users have to rely on a chair or stool to reach and grasp the lower rail 13 on the bottom of the blind or shade 12. This creates a lot of trouble and inconvenience. There is still room for improvement.
