選択されている。2. Description of the Related Art Conventionally, an electric lock is attached to a door of a building. Depending on the purpose of the building such as residential, commercial, and welfare facilities, it is a non-energized lock type or an energized lock type. Either lock is selected and attached. The electric lock may be a non-energized lock type or an energized lock type, for example, when it is attached to a door of each room of a hotel,
Anti-panic function (The door can be opened only by operating the inner operating members without operating the thumb turn.)
Since it is desirable to have an electric lock, an electric lock that can open the door is often attached only by turning the lever handle without operating the thumb turn from inside the room. on the other hand,
When installing on the door of a building such as a nursing home or public facilities, it is possible to open the door only by operating the outside operation member without operating the cylinder key from the outside of the room in consideration of disaster prevention. desirable. Therefore, such type of electric lock is attached. As described above, there are various types of electric locks at present, and the electric locks are selected according to the use of the building.

At this time, the drive piece 63 stands up in a substantially vertical state, and the upper end portion 63a thereof is located inside the second engagement portion 47 of the inner and outer engagement arms 41 and 42. Further, since the first engagement portions 46 of the inner and outer engagement arms 41 and 42 are close to the inner and outer drive cams 20 and 21, the inner and outer operation member locking means 35 and 36 are arranged in the inner and outer drive cams 20 and 21. The engaging notches 28 are respectively inserted. At this time, the inner and outer engagement arms 41 and 42 are completely the same as when they are not energized. That is, as shown in FIG. 3, the inner and outer operation member locking means 35 and 36 are inserted into the engagement notches 28 of the inner and outer drive cams 20 and 21, respectively.

Is the opposite of the above, and the operating rod 61 contracts as shown by the arrow. At this time, the driving piece 63 rotates clockwise around the shaft 62 as a fulcrum and is brought into a tilted state. As a result, the upper end portion 63a approaches the bearing portion 45 of the inner and outer engagement arms 41 and 42. Then, the inner and outer engagement arms 41, 42 rotate in opposite directions via the upper end portion 63a, so that the curved second engagement portion 47 and the small protrusion 48 of the first engagement portion 46 move in a direction away from each other. To do. Therefore, the inner and outer operation member locking means 35 and 36 are disengaged from the engagement notches 28 of the inner and outer drive cams 20 and 21. Therefore, the inner and outer operation members 7, 6
The state of blocking (lock) is canceled at the same time.

５１は枢軸１８を基準にして時計方向へと回転する。18 and 19 show the inner switching means 51 when the mode of the electric lock is "non-energized locking type electric lock 1" or "energized locking type electric lock 1". It is each explanation when switching only. As described above, the front plate 4 of the lock box 3 is removed and the opening 11a of the back plate 11 is used regardless of whether it is the lock type when not energized or the lock type when energized.
When the tip end portion 51b of the inner switching means 51 is switched to the lower side by using a doier bar (not shown), the switching means 51 rotates clockwise with respect to the pivot 18.

クされている。Therefore, the rear end portion 51 of the switching means 51
c moves upward. At this time, the engaging claw 55 at the narrow end of the switching means 51 exceeds the click feeling projection 13d. Further, since the inner engagement actuating lever 56 is lifted to the rear end portion 51c of the switching means 51 via the engagement projection 58, the engagement actuating lever 56 is located in the clockwise direction with the fixed shaft 59 as the fulcrum. Rotate a fixed amount. Then, the inner engagement arm 41 rotates clockwise about the central shaft 43 as a fulcrum to a predetermined position. As a result, the inner operating member locking means 35 is disengaged from the engagement notch 28 of the inner drive cam 20 via the small protrusion 48 on the first engagement arm 46 side of the inner engagement arm 41. Therefore, the blocked (locked) state of the inner operating member 7 is eliminated. In this case, the outer operating member 6 is still locked by the outer operating member locking means 36.

の先端部を下方へと切換える。20 and 21, when the mode of the electric lock is "non-energized locking type electric lock 1" or "energized locking type electric lock 1", the outer switching means 52 is used. It is an explanation when only switching is performed. As described above, whether it is the lock type when not energized or the lock type when energized, the front plate 4 of the lock box 3 is removed, and the outside switching means is utilized from the opening 11a of the back plate 11 by using a not-shown doila bar. 52
Switch the tip of the to downward.

である。At the time of this switching, the sliding contact relationship between the engaging claw at the narrow end of the outer switching means and the click sensation projection, the rear end of the outer switching means and the outer engagement operation. When the outer engagement actuating lever rotates counterclockwise around the other fixed shaft as a fulcrum, the outer engagement arm rotates clockwise about the central shaft by a predetermined amount. As a result, the operating mode such as the relationship in which the outer operating member locking means is disengaged from the engaging notch portion of the outer drive cam through the small protrusion on the first engaging arm side of the outer engaging arm is This is the same as the case where the switching means is switched downward.

In this case, the inner operating member 7 is still locked by the inner and outer operating member locking means 35, which is completely opposite to the case of FIG. In this way, by switching the inner / outer operation member mode switching means downward or upward, the inner / outer operation members 6 and 7 can be immediately turned.

る。As is apparent from the above description, the present invention has the following actions and effects. (1) It is possible to provide an electric lock switching device capable of freely switching the operation mode and the mode of the operation member inside and outside with one electric lock. (2) By simply removing the front plate from the lock box, it is possible to easily switch the operation mode of the electric lock and / or the mode of the inner and outer operation members. (3) Switching can be properly performed by reasonably combining the respective operating members. (4) A "click feeling" can sometimes be obtained by switching the lever-shaped switching means. (5) Even if the space between the left and right shafts that pivotally support the respective members is narrowed in order to make the lock box compact, the switching force of, for example, the inner switching means is transmitted to the inner drive cam for the inner operating member. (6) The dead bolt can be smoothly guided.
