DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock for a door which can regulate the opening and closing of a door of a vending machine and can be operated remotely.

[0002]

2. Description of the Related Art For example, the surface of a vending machine door (front wall).
Is provided with a coin slot for general users to purchase products and a plurality of selection buttons for the products. Further, a door lock for an administrator is provided on the surface of the door. Generally, a cylinder lock is used as the door lock, and a locking tongue is fixed to the rear end of the cylinder lock. The locking tongue is provided at an upper end and a lower end of the door via a connecting rod, and is connected to upper and lower lock members that protrude and disappear from the upper end and the lower end. When the cylinder lock is locked, the upper and lower lock members protrude from the upper and lower ends of the door and are engaged with the vending machine main body, so that the door cannot be opened.

In such a state, when the administrator rotates the locking tongue in the unlocking direction with the key inserted into the keyhole of the cylinder lock, the upper and lower locking members are immersed in the upper and lower ends of the door. Become. Therefore, the door can be opened,
The manager can replenish the product.

By the way, in order for the upper and lower lock members to protrude and retract, it is necessary to apply a very large force to the key.
Generally, a door lock is provided with a handle that can be operated by unlocking.

[0005] Since the vending machine is arranged at a storefront facing the road, it is necessary to take measures to prevent the handle from interfering with or mischieving a passerby. Therefore, from this fact, a door lock mainly having a drawer-type handle which is normally immersed in the surface of the door and protrudes from the surface of the door when the administrator unlocks the door so that the door can be opened and closed is mainly used. (63-1)
2274, Japanese Utility Model Laid-Open No. 3-21185, etc.).

However, there is a risk that the cylinder lock provided on the handle will be illegally unlocked or destroyed during the night when traffic is lost. In some cases, an electric lock for a door is used (see Japanese Patent Application Laid-Open No. 2-146991).

[0007] Based on the above technology, the applicant of the present invention unlocks with the password input by the administrator,
There has been proposed an electric lock for a door in which the handle is projected and the door can be opened by unlocking the door (see Japanese Patent Application Laid-Open No. Hei 8-218693 (filed on Feb. 17, 1995). The door electric lock by the applicant of the present application assumes that the door electric lock breaks down, and has an emergency unlocking mechanism (mechanical unlocking means) that can mechanically unlock the door. ing.

To explain the emergency unlocking mechanism, the door lock is provided with an emergency unlocking slide plate capable of moving a pair of latches for preventing the handle from projecting to a position where the handle can be projected. ing. The slide plate for emergency unlocking is driven by rotating a rotating disk provided on the electric lock for the door. on the other hand,
On the door of the vending machine, a cylinder lock for emergency unlocking is provided at a position apart from the electric lock for the door, and the rotor of the cylinder lock is provided with a locking tongue that rotates together with the rotor. . The locking tongue is connected to the rotating disk via a rod-like connecting rod. Therefore, when the administrator operates the emergency unlocking cylinder lock, the rotating disk is rotated and the slide plate is driven. It can be unlocked.

[0009]

By the way, taking the above-mentioned electric lock for a door by the applicant of the present invention as an example, after the electric lock for the door is attached to the door, for example, a power supply for a period until installation of a vending machine is obtained. This is very useful when the emergency unlocking mechanism has to be unlocked in a place where it is not necessary to operate the emergency unlocking mechanism via the cylinder lock.

However, there is a possibility that unauthorized unlocking or the like may be performed not for the electric lock for the door itself but for the cylinder lock for emergency unlocking.

Incidentally, the electric lock for the door hardly breaks down in normal use, and the possibility of operating the cylinder lock after installing the vending machine to release the emergency lock is very low. In addition, the provision of the cylinder lock or the like naturally affects the cost.

[0012] The present invention has been made in view of the above-described circumstances, and minimizes cost increase, has high antitheft properties, and can be mechanically unlocked as needed until installation. It is an object to provide an electric lock for a door.

The claw 56 is a member that restricts the slider 7 from moving in the unlocking direction when any impact is applied to the door lock (the anti-theft property is improved).

In the above configuration, the operation of the door electric lock will be described (the electric unlocking will be described first, and then the mechanical unlocking will be described).

At the time of locking, the handle 3 is immersed in the case 1 as shown in FIG. Further, as shown in FIG. 3, the motor cam 54 is at the initial position, and the slider 7 is urged by the compression spring 47 to
One end protrudes from 4 and is in contact with the motor cam 54. Further, the claw portion 68 of the claw 56 is engaged with the concave portion 48 (see FIG. 6) of the slider 7 to restrict the movement of the slider 7. In this state, since the one end of the slider 7 protrudes, the latches 5 cannot move inward and are engaged with the engaging recesses 15.

A gap D exists between the handle 3 and the rotary bush 2 as shown in FIG.
Can be pushed in the immersion direction by the gap D.

Next, at the time of unlocking, when the unlocking signal is received via the antenna 13 (see FIG. 2) by being remotely operated by a remote control switch or the like (not shown), the control unit (not shown) operates the motor. Then, the door electric lock is unlocked.

That is, as shown in FIG. 7, when the motor cam 54 first rotates in the direction of the arrow due to the operation of the motor, the claw 56 is pushed by the contact portion 58 of the motor cam 54 to rotate, and the slider 56 is rotated. The engagement between 7 and the claw 56 is released. At this time, since the slider 7 is in contact with the first arc portion 59 of the motor cam 54, the slider 7 is not driven.

When the motor cam 54 further rotates in the direction of the arrow and rotates to the position shown in FIG. 8, one end of the slider 7 is moved to the slider opening 24 by the second arc portion 60 of the motor cam 54. Pushed up to. In addition, the restriction release position of the slider 7 coincides with the locus drawn by the movement of the protrusion 44 of the latch 5. At this time, since the urging force of the spring 4 (see FIG. 2) is indirectly applied to the latches 5, 5, the latches 5, 5 do not move in the detaching direction.

In this state, as shown in FIG. 9, the handle 3 is moved in the direction of the arrow P to the clearance D (see FIG. 4).
When the latches 5 and 5 are pushed in,
Are in a non-contact state in the direction in which the urging force of the spring 4 acts. That is, the biasing force of the spring 4 is not applied to the latches 5 and 5.

Then, as shown in FIGS. 10 and 11, the latches 5, 5 are pulled toward each other to
Leave from 5 and 15. That is, since the protrusion 44 of the latch 5 enters the depression 51 (see FIG. 11) of the slider 7, the latch 5 is separated from the engagement recess 15.

Thus, as shown in FIGS. 12 and 13, the handle 3 projects from the surface of the case 1, and the door 8 can be opened.

At this time, the control unit (not shown) generates a control signal to return the motor cam 54 and the claw 56 to the initial positions shown in FIG. 2 after a predetermined time has elapsed.

Subsequently, when the door is closed and locked, since the motor cam 54 and the claw 56 have already returned to the initial positions as described above, the locking is completed only by immersing the handle 3 (FIG. 3 etc.).

That is, when the handle 3 is immersed in the case 1, the slider 7 is urged by the urging force of the compression spring 47 and moves to the motor cam 54 side. Then, claw 5
6 slightly rotates against the urging force of the spring 70 due to its tip shape. When the claw 56 returns, the claw portion 68 and the concave portion 4
8 (see FIG. 6) are engaged. On the other hand, with the movement of the slider 7, the latches 5, 5 move in the direction away from each other (as described above, because the urging force of the compression spring 47 is larger than the urging force of the tension spring 41), and the engagement recesses 15, 15 are formed. Be involved. Thus, the locking is completed.

Next, the unlocking when there is no power supply before the vending machine installation and the emergency unlocking will be described.

In FIG. 1, the administrator operates the operation ring 102.
When the operation member 100 is pulled in the direction of the arrow, the lock is released. That is, as shown in FIG. 14, when the emergency cam 55 at the initial position is rotated to the position shown in FIG. 15, the slider 7 is driven and unlocked in the same manner as the unlocking operation described above. become.

In addition, it goes without saying that the present invention can be variously modified and implemented without departing from the gist of the present invention.
