Description

[Detailed description of the invention] Technical field of invention The present invention relates to an electric lock that is unlocked by a card.

<Prior art and its problems> In recent years, electric locks that use cards to unlock and lock doors have become popular. This electric lock is used, for example, in a hotel, a secret room, etc. when a normal key is used to prevent theft from occurring due to someone forgetting to lock the key. Electric locks installed in hotels and confidential rooms like the one above are
The door handle and unlocking mechanism are each unique. However, the unlocking mechanism for many electric locks is attached to the wall adjacent to the door. Therefore, to open the door, first insert the card into the card reader installed in the unlocking mechanism, and after it is determined that it is the correct card and the electric lock is unlocked, you can insert it into the door handle. can.

However, the electric lock described above has the following problems.

1) Because the unlocking mechanism and door handle are largely unique,
It takes two movements to open the door. Unfortunately, this is not easy to operate, especially if you are carrying a lot of luggage.

2) Therefore, if an unlocking mechanism is installed near the door handle to improve operability even a little, electrical wiring will be required to reach the unlocking mechanism, and furthermore, the electrical wiring will be difficult due to the design of the door. Limited. Furthermore, even in this case, the problem of having to make two movements to open the door cannot be solved.

On the other hand, when modifying a door designed to use a key stick method for unlocking and locking so that cards can be used, particularly in recent years, assembling is done in a factory as a wall unit, and then the door is assembled on site. The current situation is that the use of mechanical interlocking systems is increasing in order to reduce the number of construction work required at the site.

<Purpose of the Invention> The unexploded fJA was developed in view of the above-mentioned problems, and its purpose is to integrate the door handle and card reader into a single movement to open and close the door in a single motion, with good operability and control drive. The purpose of the present invention is to provide an economical electric lock that uses a solar cell as a power source and can be used in various places.

<The uninvented electric lock is composed of a card on which various information is recorded, a card reading device that reads information from the card, a power supply that supplies power to the card reading device, etc., and a door surface. On the other hand, spinning! a door handle having a mechanism for fixing the door handle to the door; a fixing means for fixing the door handle to the door; and a means for releasing the door handle fixed to the door when a correct card is read by the card reader; The door handle has a return means for returning the rotated raised door handle to its original position, and the door handle is unlocked when the door handle is rotated and raised, and locked when the door handle is returned to its original position.

According to the present invention consisting of such a W structure, since the magnetic card reading mechanism is provided on the door handle, the door can be opened and closed with one hand and in one movement, and the degree of freedom in the design of the door is increased. It has a great effect. The present invention is also useful for women-only facilities, elderly facilities, medical facilities, and facilities for the disabled because it is suitable for people with low aptitude for mechanization. Furthermore, since the present invention is designed to place the power source on the door and the door handle, there is no need for electrical or communication work during construction. Special K, non-inventive can be used for doors that open and close in sports facilities set up in outdoor locations, event venues where renovation work is frequently performed, temporary studios for news reports such as newspapers and TV, temporary dormitories, etc. .

<Embodiments of the invention> Hereinafter, the invention will be explained in detail based on the drawings.

This is a recess provided on the side of part 0.

FIG. 3 is a control block diagram of an electric lock according to an embodiment of the present invention. In addition, in the figure, Fig. 1 (a), (b), (C
) are given the same reference numerals, and redundant explanation will be omitted.

In the figure, 31 amplifies the signal from the magnetic head 5;
Bit detection unit that performs serial code extraction using a clock, 32
33 is a code detection buffer 7 section that temporarily stores data from which the information recorded on the card 1 is serially coded by the bit detection section 31, and 33 is a code detection buffer 7 section that checks whether the data stored in the code detection section 32 is registered or not. Control is performed according to the time zone of the clock section 34, and under this control, the scanning control section 35 compares the data with the data obtained by scanning the data storage section 36, and if they match, the unlocking electromagnet 10 and the operation are performed. Display section 12
When a match is found in the code matching unit 33, the code matching unit 37 that drives the code matching unit 37 stores the data stored in the code detection buffer unit 32 and the time stamped by the clock unit 34 at that time in the transaction storage unit 38. 39 is a time display section that displays the time indicated by the clock section 34; 40 is a power supply control section 45 that controls a solar cell installed on the door handle 2 based on a signal from the card detection switch 44; 41 or a power supply section that supplies power from a generator 42 and a rectifier 43 provided so as to be interlocked with the door handle 2 to a control section of an electric lock, etc. via a secondary power source 44.

Note that the control section is provided at an arbitrary position such as the door handle 2 or the door 6 side.

Next, the operation of the electric lock having the above configuration will be explained. First, when the card holder inserts the card 1 into the magnetic card insertion slot 3 of the door handle 2, the male card detection switch 4 turns on (detects the card). The power supply control 45, which receives the detection signal from the card detection switch 4, supplies power from the solar cell 41, the generator 42, and the secondary power supply 44 to the control section of the electric lock. By inserting the card 1, the information recorded on the card 1 is read by the magnetic head 5. When the data of this read information matches the data stored in the data storage section 34, the unlocking wL electromagnet 0 operates for a predetermined period of time in response to a signal from the code matching section 33, and the operation display section 13 emits light. . The lock pin that was engaged with the hole 12 of the door hinge 7a is removed, and the door handle 2 becomes rotatable around the hinge shaft 9. Therefore, when the door handle 2 is rotated by the rotation of the hinge shaft 9 against the return spring 19, the toothed pulley 14 on the door handle side rotates, and the toothed pulley 15 on the door side rotates. 16 and rotate. Then, like the toothed pulley 15, the unlocking interlocking shaft 17 rotates, and the straight rod 22, which has the convex portion 21a that fits into the spiral groove 21 of the unlocking interlocking shaft 17, moves in a straight line.
The tip of the lock 24 moves in the direction in which it is pulled out of the wall side recess 30.

Then, when the door handle 2 is rotated until it is stopped by the stopper 18 and brought into the reversed position as shown in FIG. 1(C), the electric lock is
The locking fitting 24 is completely pulled out through the wall side recess 30 and unlocked. Finally, door 6 will be opened. Incidentally, if the stopper 18 is to be unlocked, it may be provided at a position where the door handle 2 and the door 6 form a desired angle.

Next, when the force restraining the door handle 2 is removed, the door handle 2 moves in the opposite direction to the above rotation due to the return spring 19 and returns to its original position. At this time, since the unlocking interlocking shaft 17 also rotates in the opposite direction, the lock fitting 24 engages with the wall side recess 30 again. Moreover, the unlocking electromagnet 10 is turned off after a predetermined period of time.
K to become F.

The lock bin 11 is engaged with the hole 12 of the door hinge 7a by the restoring force of the spring 20. The electric lock will be locked.
