Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-panic electric lock attached to a door of a guest room of a hotel, for example.

[0002]

2. Description of the Related Art Conventionally, an example of an electric lock attached to a door of a guest room of a hotel is described in Japanese Utility Model Publication No. 4-19180.

In this embodiment, basically, an inner and outer drive cams respectively connected to an inner handle and an outer handle are rotatably provided on a lock case, and these inner and outer drive cams are
Each can rotate independently. The lock case is provided with a combination of a plurality of members and is provided with locking / unlocking means for restricting only the rotation of the outer rotating member, and the lock case is electrically connected to the control device, and A solenoid for driving the locking / unlocking means is incorporated.

In this embodiment, when the door is closed,
Immediately, the solenoid is actuated based on the locking signal from the control device, whereby the locked state is held with respect to the handle on the outdoor side. However, since the indoor rotation member is mechanically always in the unlocked state, when the indoor handle is rotated, the retractable member retracts into the front of the lock case. Therefore, when viewed from the indoor side, even if the retractable member is locked from the outdoor side by the operation of the solenoid (the solenoid is operated, the inner handle can be rotated from the indoor side to freely unlock the retractable member. It is).

However, this type of embodiment has the following problems. Since the solenoid and the rotating body (member that rotates by key operation) to which the cylinder lock is attached are not interlocked with each other, even if an attempt is made to lock / unlock with a normal key from the outside for some reason, it cannot be done. Immediately after closing the door, the solenoid is activated and the retractable member is locked. Therefore, for some reason, it is not possible to satisfy the demand that the retractable member be held in the unlocked state not only from the indoor side but also from the outdoor side for a desired time.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional drawbacks, the present invention solves the above-mentioned drawbacks and can sufficiently satisfy the above-mentioned requirements. Furthermore, an electric lock can be locked from the indoor side. To provide an anti-panic type electric lock that can discriminate whether or not it is in a state, and in addition, can lock and unlock the retractable member from inside and outside by rational means even if the number of constituent parts is minimized. Is.

[0007]

According to the anti-panic type electric lock of the present invention, an anti-support is provided for the inner drive cam 65 for the inner handle and the outer drive cam 66 for the outer handle in the lock case 1 so that they can rotate independently of each other. In the panic type electric lock, the lock case 1 is provided with a rotating body 15 which is rotated by operating a key 91, and a sliding pressing piece 20 fixed to an operating rod 18 of an electric actuator 16 is connected to the rotating body 15. ,
On the other hand, when the outer handle 97 is operated, the driving force of the outer drive cam 66 is transmitted to the operating lever 36 that engages with the retractable member 3 via the outer engagement piece 47 that can be engaged with and disengaged from the outer driven engagement plate 56. Each of these members 56 and 47 is appropriately combined with the lock body 1, and the driving force of the rotating body 15 or the operating rod 18 of the electric actuator 16 between the outer locking piece 47 and the slide pressing piece 20 is provided. It is characterized by pivotally supporting the restricting piece 30 which is rotated by the expansion and contraction motion to engage and disengage the outer locking piece 47 with the outer driven engagement plate 56.

[0008]

First, when the rotating body is at the locking position, the locking / unlocking identification portion showing the locking can be seen from the indoor side through the identification window of the cap. In this case, the outer locking piece is separated from the outer driven engagement plate by the spring force of the outer opening spring. Therefore, even if the outer grip is rotated, the outer drive cam rotates slightly, but the actuating lever does not rotate via the outer locking piece, and the retractable member cannot be unlocked.

Next, when the rotating body rotates in the unlocking direction by the key operation, the outer locking piece engages with the outer driven engagement plate. In this case, when the outer drive cam is rotated by the outer handle, the driving force of the outer drive cam is transmitted to each member, and the retractable member retracts into the lock case. When the unlock signal is sent from the control device, the operating rod of the electric actuator extends and the outer locking piece engages with the outer driven engagement plate.

In this way, when the rotating body is rotated in the unlocking direction by the mechanical unlocking operation by the key or the electrical unlocking operation, the regulating piece is pushed and rotated by the slide pressing piece, and the outer locking piece is rotated. Engages the outer driven engagement plate.

However, even if the door is closed, the unlocked state is maintained unless a locking signal is sent from the locking operation / control device to the electric actuator by the key.
Therefore, as long as the outer handle holds the unlocked state and the outer handle rotates the outer drive cam in the direction of arrow E (clockwise), the actuating lever rotates through the outer driven engagement plate and the outer locking piece, and the stopper is rotated. The retractable member can be retracted into the lock case 1 while being pushed up by the engaging head. Therefore, to this extent, the electric lock can be said to be anti-panic from both inside and outside.

Has been formed. Reference numeral 96 is an inner handle such as a knob or lever, and 97 is an outer handle.

Next, in the above-mentioned structure, the operation state of the main part based on the object of the present invention will be described.

First, in FIG. 1, the rotating body 15 is in the locked position. In this case, as shown in FIG. 11, the locking / unlocking identification portion 90a (color indicating locking, etc.) can be seen through the identification window 94 of the cap 92 from the indoor side. The operating rod 18 of the electric actuator 16 that is interlocked with the rotating body 15 is contracted. In this case, the electric actuator 16 is in the non-energized state, and the operating rod 18 is contracted in accordance with the polarity of the magnetic body contained therein. The slide pressing piece 20 is located on the right side of the lock case 1, and the outer locking piece 47 is separated from the outer driven engagement plate 56 by the spring force of the outer opening spring 49. The restriction piece 30 for the outer locking piece is pushed up by the arcuate contact portion 47b of the outer locking piece 47 and is in a tilted state.

Therefore, even if the outer handle 97 is rotated, the operating lever 36 does not rotate via the outer locking piece 47, and the retractable member 3 cannot be unlocked.

By the way, in the above case, when the outer grip 97 is rotated, the outer drive cam 66 rotates clockwise as shown in FIG. 10, and the collision portion 69 strikes the receiving piece 70. Therefore, the driving force of the outer drive cam 66 is stopped there, and an unreasonable force does not act on the outer driven engagement plate 56.

Next, in FIG. 2, as viewed from the outside of the room, the rotating body 15 is rotated in the unlocking direction shown by the arrow A by operating the key 91, and as a result, the outer locking piece 47 is engaged with the outer driven engagement plate 56. It shows the state. In this case, the outer handle 97 is used to drive the outer drive cam
When 6 is rotated, the driving force of the outer drive cam 66 is transmitted to each member, and the retractable member 3 retracts into the lock case 1.

That is, when the rotating body 15 rotates in the arrow A (counterclockwise direction), the connecting piece 21 rotates in the arrow B direction (clockwise direction) around the first fixed shaft 23 as a fulcrum. Then, the slide pressing piece 20 is pushed to the left by the movable engaging pin 25 that moves in the vertical guide elongated hole 24, and the fixed guide pin 2
While being guided by 6, slide in the direction of arrow C (left side). At this time, the operating rod 18 of the electric actuator 16 extends, but the electric actuator 16 itself remains in the non-energized state.

The electric actuator 16 is energized when the unlock signal is sent from the control device, and the operating rod 18 extends. Then, the operation modes of the above respective members are the same.

As described above, when the rotating body 15 is rotated in the unlocking direction by the mechanical unlocking operation by the key 91 or the electrical unlocking operation, the regulating piece 30 is pushed by the pushing portion 20c of the slide pushing piece 20. , And rotates in the direction of arrow D (counterclockwise) about the second fixed shaft 31. As a result, the outer engagement piece 47 rotates downward (clockwise) against the spring force of the outer opening spring 49, and the engagement portion 47c engages with the arc-shaped engagement portion 58 of the outer driven engagement plate 56. .

Therefore, even if the door 93 is closed, the unlocked state is maintained unless the locking operation is performed by the key 91 or the locking signal is not sent from the control device to the electric actuator 16. Therefore, when the outer handle 97 rotates the outer drive cam 66 in the arrow E direction (clockwise direction), the operating lever 36 rotates about the third fixed shaft 37 as a fulcrum via the outer driven engagement plate 56 and the outer locking piece 47. And stopper 13
Is rotated in the direction of arrow F (clockwise) while being pushed up by its engaging head portion 38. As a result, the retractable member 3 retracts into the lock case 1.

[0054]

As is apparent from the above description, in the present invention, when the rotating body is rotated in the unlocking direction by the mechanical unlocking operation by the key or the electrical unlocking operation,
The restricting piece is pushed by the slide pressing piece to rotate, and the outer locking piece engages with the outer driven engagement plate. This unlocked state is maintained even if the door is closed, unless a locking operation is performed by a key and / or a locking signal is sent from the control device to the electric actuator. Therefore, as long as the unlocked state is retained,
The retractable member can be freely retracted into the lock case 1 by rotating the outer handle, and as long as this is the case, the electric lock is anti-panic from both inside and outside. Therefore, the drawbacks described in the section of the prior art can be solved, and the conventional requirements can be sufficiently satisfied.
