The pedestal 12 includes a key hole 14 for a cylinder lock, a receiver 15 for reading an ID code (identification signal) of a card key (not shown), an operation button 16, an indicator 17, and the like. In particular, in this embodiment, a battery case 18 that forms the auxiliary power supply 50 is provided.
The auxiliary power supply 50 is formed by setting a dry battery in the battery case 18.

Furthermore, in the electric lock device of this embodiment, as shown in FIG. 1B, a base 22 that supports the inner handle 21 is fixed to the inner surface of the door 13.
The pedestal 22 is a vertically long hollow body having a trapezoidal cross section like the pedestal 12 outside the door. However, the pedestal 22 is formed as a pedestal having a slightly higher height than the pedestal 12.
The pedestal 22 is screwed to the door 13 so as to cover an electric lock device comprising the electric lock 23 and the controller 24 provided on the door 13, and the pedestal 12 has an electric lock device. A battery cover 25b of a battery power source 25 for supplying power to the battery is provided.

The battery power supply 25 has a configuration in which a battery cover 25b forming a part of the base 22 is removed and a dry battery is accommodated in the battery case 25a. In this embodiment, four AA dry batteries are connected in series. It is configured to be stored as.

And a temporary locking latch lock that causes the latch bolt 29 to protrude and enter the strike hole of the strike by operating the handle 11 or 21.

Next, the battery case 18 of the auxiliary power supply 50 that is a feature of the present invention will be described.
As shown in FIGS. 2, 3, and 4, the battery case 18 of the auxiliary power supply 50 is formed in a substantially box shape with a synthetic resin material, and is housed in a lower portion of the base 12 outside the door.
That is, in the lower part of the pedestal 12, rail groove grooves 12 a and 12 b are formed on the upper and lower sides on one side, and guide rails 18 a and 18 b are provided on the upper and lower sides of the battery case 18. The guide rails 18a and 18b are slidably fitted into the rail groove grooves 12a and 12b.

Further, a click mechanism as shown in FIG. 8 is provided at the circular dotted line 30 shown in FIG. 2, and the battery case 18 is held in the storage position by the click mechanism.
As shown in FIG. 8, the click mechanism is provided in the hole 12 c provided on the inner surface of the base 12, the small ball 32 pushed by the spring 31 provided in the hole 12 c, and the battery case 18. The click groove 18c is formed.

Therefore, when the battery case 18 is pulled out, the battery case 18 moves downward (in the direction of the arrow in FIG. 4A) of the base 12 as shown in FIGS.
When the battery case 18 is pulled out, the stopper portions 18f and 18g provided on the restriction plate 18d extending upward from the case are locked by the upper ends of the rail groove grooves 12a and 12b. The drawer is stopped and the battery case 18 is held at the drawer position.

As shown in the figure, the battery case 18 of the present embodiment is configured to accommodate four AA-type dry batteries, similarly to the battery power supply 25 inside the door, but the width of the battery case 18 is sufficient due to the pedestal width. However, the case width is insufficient just by pulling it out, and it is impossible to store AA batteries.
Therefore, the battery case 18 is formed by the case body 33 and the slide case 34, and the slide case 34 is configured to move in the lateral direction (the arrow direction in FIG. 5) as shown in FIG.

By increasing the case width in this way, it becomes possible to store AA batteries.
As shown in the figure, the battery case 18 is provided with four battery housing portions 35a, 35b, 35c, and 35d, and the battery housing portions 35a to 35d are provided with a plus terminal 36a and a minus terminal 36b.

  The positive terminal 36a and the negative terminal 36b are arranged so that four dry batteries accommodated in the battery accommodating portions 35a to 35d are connected in series, and the positive terminal 36a and the battery in the battery accommodating chamber 35a are further connected. An external lead cord 37 is connected to the minus terminal 36b of the storage chamber 35d, and a power feeding circuit for feeding power to the electric lock device including the electric lock 23, the controller 24, the receiver 15 and the like is formed through the cord 37.

The uppermost guide groove 33a and the lowermost guide groove 33a are guide grooves that limit the movement of the sliding projection 34a by shortening the length in order to determine the movement limit of the slide case 34.

The electric lock device formed as described above can be powered by the battery power supply 25 when the stored power of the battery power supply 25 is equal to or higher than a certain level.
Therefore, when the card key is directed to the receiver 15, the ID code of the card key is read and sent to the controller 24.
Since the controller 24 identifies the ID code and enables the electric lock 23 according to the identification result, when the operation button 16 is pushed from outside the door, the locked electric lock 23 is unlocked.

On the other hand, when the stored power of the battery power supply 25 is consumed to a certain level or lower, the electric lock device is in a non-driven state, so the locked door 13 attempts to unlock using the card key. However, the electric lock 23 does not unlock.
In such a case, the key can be unlocked by inserting a key from the key hole 14 and operating the cylinder lock.
However, since the cylinder key may be left in the room and go out, in such a case, if it cannot be unlocked due to exhaustion of the battery power supply 25, the cylinder key is locked out.

Therefore, in the present embodiment, when unlocking from the outside of the door is not possible as described above, the battery case 18 is pulled out, and the dry battery is accommodated in the battery case 18 to form the auxiliary power supply 50.
Therefore, since the auxiliary power supply 50 is connected in parallel to the battery power supply 25 as shown in FIG. 9, in order to supply power instead of the battery power supply 25, the electric lock device can be driven.
As a result, since the electric lock 23 can be unlocked from the outside of the door using the card key, it is possible to solve an emergency problem that the lock is kept locked.

If the auxiliary power supply 50 is used for unlocking, the door 13 can be opened, so that the battery cover 25b of the battery power supply 25 can be opened and the consumed dry battery can be replaced with a new dry battery.
In this case, the dry battery stored in the battery case 18 of the auxiliary power supply 50 is only used temporarily and can be used sufficiently. Therefore, the dry battery taken out from the battery case 18 is replaced with the battery case of the battery power supply 25. It can also be stored in 25a.

As mentioned above, although preferable embodiment was described, this invention can be implemented similarly about the electric lock apparatus which is not provided with the cylinder lock.
Further, the dry batteries that can be stored in the battery case 18 of the auxiliary power supply 50 are the same type and the same number as the dry batteries of the battery power supply 25. It can also be used for dry batteries.

Furthermore, when the width and height of the pedestal 12 can be made sufficiently large, the battery case 18 need not be provided with the slide case 34.
In addition, an electric lock device that includes a portable device that outputs an ID code as a radio signal and uses an output signal of a receiver that receives the radio signal can be similarly implemented.

Even when the auxiliary power supply 50 is used in combination with an electric lock device that converts a household AC100V into a predetermined DC voltage and is used as a DC power source, if the present invention is applied, an emergency such as a power failure will occur. The electric lock device can be driven.
In this case, the auxiliary power supply 50 may determine the number of dry batteries according to the output voltage of the DC power source.

  This can be applied to an electric lock provided for a front door of a building.
