Thus, by attaching the upper drive unit 35 and the lower drive unit 37 to the grip thumb turn unit 21, the upper thumb turn 31 can be easily electrically driven by the upper motor 53 and the lower thumb turn 33 can be easily electrically driven by the lower motor. It is like that.

  As shown in FIG. 4, in order to attach the grip thumb turn unit 21 to the door indoor surface 19, a pair of upper and lower attachment plates 63 are fixed to the door indoor surface 19. The mounting plate 63 is provided with a through-hole 65 through which the operating shaft (tail piece) of the upper cylinder lock 15 and the lower cylinder lock 17 passes. The mounting plate 63 is provided with a plurality of screw cylinder fixing holes 69 that coincide with the fixing screw cylinder 67 protruding from the existing outdoor grip unit 13. The existing outdoor grip unit 13 is attached to the door chamber outer surface 41 by screwing an outdoor grip fixing screw 71 (see FIG. 7) passed through the screw tube fixing hole 69 from the door indoor surface side to the fixing screw tube 67. Fixed. On the other hand, the grip thumb turn unit 21 is fixed to the door interior surface 19 with screws fixed to a unit fixing piece 73 erected on the mounting plate 63.

  By the way, a bottom plate 75 (see FIG. 5) provided on the door chamber inner surface 19 is overlaid on the communication unit through hole 43 (see FIG. 7) to cover the communication unit through hole 43. A fixing hole 77 and a wiring hole 79 are formed in the bottom plate 75. These fixing hole 77 and wiring hole 79 are smaller than the communication unit through hole 43. A leader cover 81 is fixed to the door side surface of the bottom plate 75 by a fixing screw 83 inserted from the indoor side surface of the bottom plate 75. A control board 61 is accommodated inside the leader cover 81 in a direction perpendicular to the door interior surface 19. The control board 61 is integrated with a communication board (not shown) provided with an antenna unit 85. Control wiring is electrically connected to the control board 61, and the control wiring is led out from the wiring hole 79 to the door interior surface 19 side.

The upper motor 53, the gear train 59, and the operation board 93 are covered with the drive cover 101.

  For example, a die-cast concealing plate 103 (see FIG. 5) is disposed on the door chamber outer surface 41. The concealing plate 103 exposes the antenna unit 85 from the antenna exposing hole 105, thereby allowing the communication unit through hole 43 and the communication unit 39 to be exposed. To close the gap. A plate fixing cylinder 107 protrudes from the back surface of the hidden plate 103, and the plate fixing cylinder 107 is fixed to the bottom plate 75 by a plate fixing screw 109 penetrating the drive cover 101 and the bottom plate 75 from the indoor side. That is, the hidden plate 103 is fixed with the bottom plate 75 sandwiching the door 23. The drive cover 101 is further covered with a unit cover 111. The unit cover 111 is screwed to both the bottom plate 75 and the grip thumb turn unit 21. Accordingly, the bottom plate 75 is screwed to the upper drive unit 35 and is deformed at the time of destruction, but is difficult to drop off, and becomes a barrier to approaching the thumb turn. The lower drive unit 37 is directly screwed to the door interior surface 19 or the grip thumb turn unit 21 regardless of the bottom plate 75.

  As described above, the upper drive unit 35 is attached to the door interior surface 19 via the bottom plate 75, and includes an upper motor 53 that is controlled in operation by the control board 61 and rotates the thumb turn shaft 51.

  The upper drive unit 35 accommodates the control board 61, and the control board 61 is connected to the communication unit 39, the upper motor 53, and the lower motor. The upper drive unit 35 is provided with an indoor side locking / unlocking button 95 connected to the control board 61 so as to be exposed to the indoor side. The control board 61 rotates the upper motor 53 and the lower motor in response to depression of the indoor side locking / unlocking button 95 so that the thumb turn shaft 51 can be rotated in the locking or unlocking direction. In addition, the LED marking part 89 in the vicinity of the indoor side locking / unlocking button 95 is connected to the control board 61, and clearly indicates the locking / unlocking state by the emission color or the like.

  The grip thumb turn unit 21 has a wiring space 113 shown in FIG. In this wiring space 113, a power supply wiring is routed. In the electric thumb turn unit 11, the battery box 47 and the control board 61 are connected by a power supply wiring (not shown), and the control board 61 and the lower motor are connected by a control wiring (not shown). , Local electrical wiring work is no longer necessary.

  In the electric thumb turn unit 11, the member 117 to be detected is attached to the door frame 115 shown in FIG. 3 provided with the door 23 in the vicinity of the grip thumb turn unit 21. On the other hand, the lower drive unit 37 fixed to and integrated with the grip thumb turn unit 21 accommodates a closing detection sensor 119 shown in FIG. 2 that detects the closing by detecting the detected member 117. The door closing sensor 119 is connected to the control board 61 by a control wiring. In this embodiment, the door closing detection sensor 119 is provided in the lower drive unit 37, but the door closing detection sensor 119 may be accommodated in the upper drive unit 35 or the grip thumb turn unit 21.

  Further, a spacer 121 shown in FIG. 8B is provided between the bottom plate 75 and the unit cover 111 so as to be sandwiched. The spacer 121 is sandwiched between the bottom plate 75 and the communication unit 39 in accordance with the thickness of the door 23 so that the communication unit 39 can be raised.

Next, the operation of the electric thumb turn unit 11 having the above configuration will be described.
7 is an exploded perspective view for explaining the assembly of the electric thumb turn unit 11 shown in FIG. 1 to the door 23, FIG. 8A is a perspective view of the communication unit 39 attached to the door 23 having a small thickness, and FIG. FIG. 3 is a perspective view of a communication unit 39 attached to a door 23 having a large thickness.
In the electric thumb turn unit 11, when it is desired to replace the non-electric lock with the electric lock, the existing indoor grip unit is removed. A communication unit through hole 43 shown in FIG. 7 for attaching the communication unit 39 is formed in a slit shape on the door chamber inner surface 19 and the door chamber outer surface 41. This completes the processing of the door 23.

  A grip thumb turn unit 21 integrated with a communication unit 39 is attached to the door chamber inner surface 19. The communication unit 39 including the antenna unit 85 exposed to the door chamber outer surface 41 is inserted into the communication unit through hole 43 formed through the door 23. The communication unit 39 is thinned by arranging the control board 61 that must be accommodated in a direction perpendicular to the door interior surface 19. Thereby, the communication unit through-hole 43 can be formed in a vertically long slit shape.

  Even if the antenna section 85 has a small and small cross-sectional area similar to the communication unit through-hole 43, it protrudes from the outer surface 41 of the door chamber, so that the exposed area is increased and the exposed surface becomes multidirectional. Good antenna performance is ensured. That is, the communication unit through-hole 43 can be formed in an elongated shape without deteriorating the antenna performance. As a result, it is difficult to insert tools and fingers from the outdoor side through the communication unit through-hole 43. Moreover, since the communication unit through-hole 43 is covered with the above-mentioned bottom plate 75 attached to the door indoor surface 19, fireproof performance is ensured.

  The hidden plate 103 is fixed to the door chamber outer surface 41 with the door 23 sandwiched between the bottom plate 75 provided on the door chamber inner surface 19. The hidden plate 103 closes the gap between the communication unit through hole 43 and the communication unit 39, so that the crime prevention strength is increased.

  The thumb turn shaft 51 for inputting the locking / unlocking operation force and the operating piece (not shown) for inputting the latch operation force protruding from the grip thumb turn unit 21 are connected to the lock box in the same manner as the existing indoor side grip unit. Basically, the change to the electric lock is completed so far.

  The new thumb turn shaft 51 connected to the lock box can be rotated by the motor (53) when the meshing member 55 and the output gear 57 are meshed with each other. The rotation of the motor is controlled by the control board 61 to which a locking / unlocking signal is input from the communication unit 39, the indoor locking / unlocking button 95, or the outdoor locking / unlocking button 87. A battery box 47 is accommodated in the grip thumb turn unit 21, and the battery box 47 is connected to the control board 61, the communication unit 39, the motor, and the power supply wiring previously routed inside the grip thumb turn unit 21. This eliminates the need for local wiring work.

  The battery 45 is accommodated in the pedestal 25 of the electric thumb turn unit 11 and arranged outside the door 23. At the same time that the pedestal 25 is attached to the door 23, the installation of the battery 45 is completed, and it is not necessary to secure a new battery accommodating space in the door 23. Accordingly, it is possible to eliminate the hole forming process for the door 23 for recessing the battery box 47 and the like on the door interior surface 19. That is, the strength of the door 23 is not reduced.

  Further, in the electric thumb turn unit 11, the engagement member 55 is provided on the thumb turn shaft 51, which is the same structure as the non-electric lock, and the output gear 57 that engages with the engagement member 55 is exposed to the drive unit. The lock box can be used as it is. Therefore, it is not necessary to replace the existing lock box with the motor built-in lock box, and the electric lock can be easily obtained. In this way, the motor conventionally provided in the lock box can be easily provided outside the lock box.

  Further, in the electric thumb turn unit 11 of the present embodiment, even if the thumb turn increases as a plurality of upper thumb turns 31 and lower thumb turns 33, an upper motor 53 and a lower motor are added to the grip thumb turn unit 21, and these are fed. It is connected in advance by wiring for use. Thereby, it is possible to easily form an electric lock even for a structure having a plurality of cylinders and a plurality of thumb turns with improved crime prevention. Accordingly, it is possible to easily cope with a configuration in which the cylinder lock and the thumb turn are provided on the upper and lower sides and the crime prevention property is enhanced.

  Further, by incorporating the door closing detection sensor 119 in the grip thumb turn unit 21 in advance, installation work and wiring work of the door closing detection sensor 119 at the site are halved only to installation work of the detected member 117. Thereby, the installation work of the closing detection sensor 119 to the door 23 and the wiring work between the closing detection sensor 119 and the control board 61 can be omitted.

  Furthermore, as shown in FIG. 8A, when the spacer 121 is not sandwiched between the bottom plate 75 and the communication unit 39, and when the spacer 121 is sandwiched as shown in FIG. 75, that is, the distance from the door interior surface 19 to the protruding end of the antenna portion 85 can be varied. Thus, even when the same communication unit 39 is attached to the thick door 23A having different thicknesses, the antenna portion 85 is always attached with the predetermined protrusion amount d from the door chamber outer surface 41 by appropriately using the spacer 121. It becomes possible. Thus, in the communication unit for electric locks, the protruding length of the antenna portion 85 can be made constant and the antenna performance can be stabilized by sandwiching the spacer 121 with respect to the doors 23A having different thicknesses.

  Therefore, according to the mounting structure of the communication unit for the electric lock according to the present embodiment, the communication unit through hole 43 through which the communication unit 39 including the antenna unit 85 can pass is a slit shape. Can be reduced. And since this communication unit through-hole 43 is a small through-hole, it becomes possible to suppress the fall of airtightness, without impairing the fireproof performance of the door 23 itself, and waterproof performance largely. Even if the antenna portion is broken, the communication unit through-hole 43 that is the through-hole is slit-like and small, so that the crime prevention performance is not lowered. Further, the processing on the door 23 is small and the design is not deteriorated.

  In the above-described embodiment, the communication unit 39 is provided in the electric lock mainly including the electric thumb turn unit 11 that electrically operates the thumb turn. However, the communication unit 39 is not limited to the electric thumb turn described above. In a so-called electric lock such as a locking / unlocking device in which a motor is built in a lock box or a lock with a surface disposed on a door surface, the same effect as described above can be obtained if the communication unit 39 is provided. Thus, the processing on the door 23 can be reduced.
