1. Field of the Invention
The present invention relates to a motorized blind, and more particularly to a motorized blind that is repaired easily and rapidly.
2. Description of the Related Art
A conventional motorized blind comprises a headrail, a plurality of slats mounted on the headrail, an actuating device mounted on the headrail to lift or lower the slats, and a power supply device mounted on the headrail and electrically connected to the actuating device to supply an electric power to the actuating device to lift or lower the slats. However, the battery of the power supply device is mounted in the headrail, so that the battery cannot be removed from the headrail easily and conveniently, thereby causing inconvenience to a user to replace the battery of the power supply device when the electric power is not sufficient.
The primary objective of the present invention is to provide a motorized blind that is repaired easily and rapidly.
Another objective of the present invention is to provide a motorized blind, wherein the battery or the chargeable battery of the power supply device is mounted in the bottom rail, so that the battery or the chargeable battery can be removed from the bottom rail easily and conveniently, thereby facilitating a user replacing the battery or charging the chargeable battery of the power supply device when the electric power is not sufficient.
A further objective of the present invention is to provide a motorized blind, wherein both of the power supply device and the actuating device mounted in the bottom rail, thereby facilitating maintenance of the power supply device and the actuating device.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The power supply device includes a battery box 21 mounted in the bottom rail 4 to receive a battery 22 or a chargeable battery 23, and a conducting drive cord 31 having a first end electrically connected to the battery 22 or the chargeable battery 23 and a second end extended through the battery box 21, the respective through hole 32 of each of the slats 3 and the drive shaft 24 and electrically connected to the actuating device 2 to supply the electric power to the actuating device 2.
The motorized blind further comprises at least one lift cord 33 having a first end secured to the bottom rail 4 and a second end extended through the respective through hole 32 of each of the slats 3 and wound around the drive shaft 24, so that the lift cord 33 is moved by rotation of the drive shaft 24 to lift or lower the slats 3.
The second end of the conducting drive cord 31 is wound around the drive shaft 24, so that the conducting drive cord 31 is moved by rotation of the drive shaft 24 to lift or lower the slats 3. Thus, the conducting drive cord 31 co-operates with the lift cord 33 to lift or lower the slats 3. The contacts of the conducting drive cord 31 and the actuating device 2 adopts the type of the rotor and the electric brush.
As shown in
As shown in
In operation, the actuating device 2 is electrically connected to the battery 22 or the chargeable battery 23 of the power supply device by the conducting drive cord 31 to drive and rotate the drive shaft 24, so that the conducting drive cord 31 and the lift cord 33 are moved by rotation of the drive shaft 24 to lift or lower the slats 3.
As shown in
Referring to
Accordingly, the battery 22 or the chargeable battery 23 of the power supply device is mounted in the bottom rail 4, so that the battery 22 or the chargeable battery 23 can be removed from the bottom rail 4 easily and conveniently, thereby facilitating a user replacing the battery 22 or charging the chargeable battery 23 of the power supply device when the electric power is not sufficient. In addition, both of the power supply device and the actuating device 2 mounted in the bottom rail 4, thereby facilitating maintenance of the power supply device and the actuating device 2.
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 cover such modifications and variations that fall within the true scope of the invention.
