Description

  The present invention relates to an electric lock mounting structure for mounting an electric thumb turn to a door.

  Conventionally, an electric lock mounting structure (hereinafter abbreviated as mounting structure) for mounting an electric thumb turn on a door is known. This electric thumb turn must be firmly attached to the door because it requires crime prevention and load resistance. 8 and 9 show one configuration of such a mounting structure. The attachment structure 101 includes a lock 3 fixed in the internal space of the door 2, a connection adapter 4 having a rotary shaft 41 that opens and closes the lock of the lock 3, an electric thumb turn 5 that rotates the rotary shaft 41 electrically, and a door 2. The mounting bracket 6 attached to the connection adapter 4 in a state of being in contact with the indoor side surface 21 and the spacer 107 that fills the space between the connection adapter 4 and the mounting bracket 6 are provided. A cylinder lock 8 is provided on the outdoor side surface 22 of the door 2 so as to be connected to the lock 3, and the lock of the lock 3 can be opened and closed by a key 81.

  The lock 3 is fixed to a frame (not shown) provided in the door 2, and the dead bolt 31 is made to protrude and retract from the opening 33 of the front plate 32 to perform locking and unlocking. The connection adapter 4 is connected to the lock 3 with a screw (not shown). When the rotating shaft 41 of the connection adapter 4 rotates, the lever (not shown) of the lock 3 moves and causes the dead bolt 31 to appear and disappear from the opening 33.

  The electric thumb turn 5 rotates the rotating shaft 41 by electric power according to a switch (not shown) or a signal from the outside. The mounting bracket 6 has a hole through which the rotary shaft 41 penetrates in the center, and is attached to the connection adapter 4 by a mounting screw 62. The mounting screw 62 passes through the through hole 61 of the mounting bracket 6 and the through hole 1071 of the spacer 107 and is screwed into the screw hole 42 of the connection adapter 4. Thereby, the mounting bracket 6 clamps the door 2 with the connection adapter 4 through the spacer 107. In addition, the mounting bracket 6 bends a portion extending vertically to the indoor side, and has a through hole 63 in the bent portion. The thumb turn fixing screw 64 passes through the through hole 63 and is screwed into the screw hole 51, and the mounting bracket 6 holds the electric thumb turn 5. Thus, by holding the door 2 between the mounting bracket 6 and the connection adapter 4, the electric thumb turn 5 and the door 2 can be prevented from rattling and the electric thumb turn 5 can be firmly attached to the lock 3.

  In such a mounting structure 101, the thickness of the spacer 107 must match the mounting interval length between the connection adapter 4 and the mounting bracket 6. If the thickness of the spacer 107 is large, a gap is generated between the mounting bracket 6 and the indoor side surface 21 of the door 2, and the electric thumb turn 5 cannot be firmly fixed. Further, when the spacer 107 is thin, a space is generated between the mounting bracket 6 and the spacer 107, and the door is deformed when the mounting screw 62 is forcibly tightened by tightening the mounting screw 62 to fix the mounting bracket 6. However, since the thickness of the door 2 varies greatly depending on the door 2, the mounting interval length between the connection adapter 4 and the mounting bracket 6 also varies depending on the door 2. For this reason, it is necessary to prepare spacers 107 having various thicknesses according to the mounting interval length, and it takes time to select the spacer 107 that matches the mounting interval length.

  There is also known a mounting structure in which the spacer is screwed to adjust the mounting interval length between the connection adapter and the mounting bracket. FIG. 10 shows one configuration of such an attachment structure. The connection adapter 4 has a cylindrical fixing portion 43 in which an external screw is formed at the base portion of the rotating shaft 41, and a rotation spacer 173 that is screwed into the external screw of the cylindrical fixing portion 43 is provided. Yes. By rotating the rotation spacer 173, the mounting interval length between the connection adapter 4 and the mounting bracket 6 can be adjusted. However, in this type of mounting structure 101, in order to mount the electric thumb turn 5, the rotating spacer 173 whose position is adjusted by the scale amount is temporarily fixed with the rotation screw 176 and then the connection adapter 4 is attached to the lock 3. Confirm that the position of the rotating spacer 173 is aligned with the indoor side surface 21 of the door 2, then remove the connection adapter 4 from the lock 3, tighten the locking screw 176, and reattach the connection adapter 4 to the lock 3. Therefore, it takes time to adjust the position of the rotating spacer 173.

  Further, a lock mounting structure is known in which a thumb turn is directly attached to a lock without using a spacer (see, for example, Patent Document 1).

However, in the lock mounting structure as shown in Patent Document 1, the thumb turn corresponding to the thickness of the door must be provided, which increases the cost.
