ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lock, and more particularly to an electrical lock device.
2. Description of the Prior Art
Typical electrical lock devices comprise a solenoid device for actuating a plunger to lock the door or to release the door. For some typical electrical lock devices, the plunger may be actuated to lock the door only when it is energized. For other typical electrical lock devices, the plunger may be actuated to lock the door only when it is not energized. The users or the workers have to purchase the correct lock devices.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional electrical lock devices.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an electrical lock device which may be adjusted to lock the door either when the solenoid device is energized or is not energized.
In accordance with one aspect of the invention, there is provided an electrical lock device comprising a housing including a chamber formed therein, a lever pivotally secured to the housing at a pivot shaft, a solenoid device received in the chamber of the housing, and means for adjusting and securing the solenoid device to the housing between a first position where the solenoid device is disengaged from the lever when the solenoid device is energized and a second position where the solenoid device is engaged with the lever when the solenoid device is energized.
The housing includes a first hole and a second hole formed therein, the adjusting and securing means includes a fastener engaged through the first hole of the housing and secured to the solenoid device for securing the solenoid device to the housing at the first position, and engaged through the second hole of the housing and secured to the solenoid device for securing the solenoid device to the housing at the second position The first hole and the second hole of the housing are arranged in a stagger way relative to each other. The solenoid device includes a bracket secured thereto, the bracket includes a first screw hole and a second screw hole formed therein for selectively threading with the fastener.
A guiding means is further provided for guiding the solenoid device to move in the housing and includes an oblong hole formed in the housing, and a knob slidably received in the oblong hole of the housing and secured to the solenoid device for guiding the solenoid device to move in the housing when the knob is slid along the oblong hole of the housing.
The solenoid device includes a plunger slidably received therein, and a block secured to the plunger, the block is caused to engage with the lever and to prevent the lever from being depressed inward of the housing.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
