Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door lock device that is applied to the door of each room in, for example, a hotel or the like.

Conventionally, this type of door lock device uses a mechanism that verifies a magnetic card to unlock the electromagnetic lock, but when such a mechanism is adopted, the electromagnetic lock, card reader, electric control unit, etc. A power supply for supplying power to the needle and its power wiring are required, and there are disadvantages such as the needle installation work becomes a major loss and the construction cost becomes expensive.

In order to solve the above problem, the present invention eliminates the need for a power source and its power wiring by providing a power generating means for generating the electric power necessary for opening and closing the lock and an electric storage means for storing the generated electric power in the door. The purpose of this invention is to provide a new door lock device that simplifies the needle installation work and reduces the cost of the work, as well as contributes to power saving.

In order to achieve this purpose, in the present invention, an operating handle is attached to the door, and when the person entering the room rotates the operating handle, a power generation means is activated to generate electric power, and the generated electric power is stored. It is configured to store electricity in stages and supply the necessary power to the electromagnetic lock and electric control unit.

Therefore, according to the present invention, the power necessary for opening and closing the lock can be obtained automatically upon entering the room, so there is no need for a power supply or its power wiring, which simplifies the lock fitting process. It has excellent effects such as reducing construction costs and contributing greatly to power saving.

Embodiments of the present invention will be specifically described below based on the drawings.

FIG. 1 shows the configuration of the door section as seen from the outside. On the outer surface of the door 1, there is a card reader 90 for reading information recorded on a magnetic card A, and a card reader 90 for reading information recorded on a magnetic card A, and a card reader 90 for use in power generation operations, etc., which is a feature of the present invention. An operating knob 1 and a handle 2 are provided.

The operating handle 2 is connected to a locking lever 4 and a power generator 7 via a clutch mechanism 3, as shown in FIGS. 2 and 3.

The clutch mechanism 3 includes a drive gear 30 connected to the operating handle 2, a switching lever 31, an actuating arm 32 connected to the switching lever 31, and a driven gear attached to the tip of the actuating arm 32 and meshing with the driving gear 30. The rotational force of the operating handle 2 is transmitted to either the locking lever 4 or the power generator 7 by switching the switching lever 31.

The locking lever 4 has a rack portion 4 that meshes with the driven gear 33.
1, and constitutes an electromagnetic lock 6 together with a solenoid 5 disposed in the intermediate portion. This electromagnetic lock 6 is in the unlocked state when the plunger 51 of the solenoid 5 is retracted and energized, and the locking lever 4 reciprocates by rotating the operation knob 1 and the handle 2 to open the door. [] When the solenoid 5 is deenergized, the plunger 51 engages in the cut groove 43 provided in the locking lever 4, and the electromagnetic lock 6 is in the locked state. , and the reciprocating movement of the locking lever 4 is prevented.

The power generator (67) sequentially meshes intermediate gears 72, 73, and 74 with the large-diameter gear 71 that meshes with the driven gear 33, and rotates the generator 70 at an increased speed according to these gear ratios.
Generates the power necessary for unlocking.

Electric power generated by the generator 70 is stored in the capacitor 8 via a diode 81, as shown in FIG.

The electric power stored in the capacitor 8 is supplied to the control section 9, and the unlocking signal i from the control section 9 turns on the drive transistor 82, thereby supplying power to the solenoid 5 via the resistor 83.

The control unit 9 reads recorded information on the magnetic card with a reading circuit 92 via a magnetic head 91, and reads this information into a first storage circuit 9.
3. At the same time, this information and the verification data preset in the second storage circuit 94 are extracted and the comparison circuit 9
5, and if the two match, the unlocking signal i is output. Note that the comparison circuit 95 and the first and second storage circuits 93 and 94 can be configured as appropriate circuits, such as being constituted by a microcomputer circuit consisting of a CPU, RAM, and ROM.

Thus, when the person entering the room turns the operating handle 2 after tilting the switching lever 31 to the power generation side, the generator 70 is forcibly rotated to generate electricity, and the generated power is stored in the capacitor 8. Next, when the magnetic card A is set in the card reader 90, the controller 9 operates due to the discharge of the capacitor 8, and performs each operation of reading and verifying the card information.When the card information is determined to be appropriate, the solenoid is activated. 5 is energized, and the electromagnetic lock 6 is unlocked. After that, when the person entering the room moves the switching lever 31 to the opposite side and continues to rotate the operating handle 2, the locking lever 4 retreats and the locking part 42 at the tip escapes from the groove 11, opening the door 1. becomes possible.
