(1) Lock to which the present invention is applied FIG. 1 is an example of a lock X provided with a state detection device Y for a lock member for a handle cam according to the present invention, in a state where the lock member 13 locks the handle cam member 3. It is a schematic explanatory drawing. When the lock member 13 is engaged with the handle cam member 3, the lock member position detection means 18 can reliably detect a signal indicating the lock state of the handle (not shown).

  First, components of the lock X will be described. This lock X has a long box-like lock box 1 that houses several mechanisms. Although the upper box side of the long lock box 1 is omitted, the front 1a, the back plate 1b, and the rear It is formed with a wall 1c, an upper wall 1d, and a bottom wall 1e. The front 1a can be removed from the back plate 1b, and when the front 1a is removed from the back plate 1b, a rotatable movable frame body 82, which will be described later, provided in the opening of the back plate 1b and a main switching that can be switched in the vertical direction. The tip 66a of the lever 66 can be seen (see FIG. 2). In the present invention, the switching means 65 including the main switching lever 66 and the like is not an essential matter of the invention. The switching means 65 is described in the meaning of understanding the implementation environment of the invention.

  Now, the elongate lock box 1 of this embodiment is attached to the vertical hook c with the narrow width | variety of a door (for example, glass door). Therefore, this lock box 1 is formed corresponding to the width of the narrow vertical hook, for example.

  Next, reference numeral 2 denotes a lock piece (for example, an engagement member referred to as a dead latch, a latch bolt, or a lock bolt) provided in the lock box 1 so as to be able to advance and retract. The lock piece 2 has a handle at the rear end 2a. It has a penetrating or recessed unnumbered engaging portion that engages with the cam member 3. The handle cam member 3 is pivotally supported by a first fixed shaft 4 (a handle shaft in some embodiments) whose base end portion 3a is located below the lock piece 2, and below the base end portion 3a, A short-piece-shaped first engagement portion 3b that engages with the inner and outer protrusions 5 and 6 provided at inner ends of inner and outer operation members (for example, push-pull handles) (not shown) extends radially outward. ing. An arm-shaped second engaging portion 3c extends above the base end portion 3a, and the arm-shaped second engaging portion 3c penetrates the engaging portion of the rear end portion 2a of the lock piece 2 described above. Engage state. And the small roller 7 is rotatably provided in the taper-shaped front-end | tip part 3d which protrudes from the lock piece 2 of the arm-shaped 2nd engaging part 3c.

  Reference numeral 11 denotes a stopper piece for a lock piece supported by a second fixed shaft 12 located slightly above the lock piece 2, and a downward arc-shaped notch-like engagement portion formed on the lower side of the stopper piece 11 for the lock piece. The small roller 7 of the handle cam member 3 is engaged and disengaged.

  Reference numeral 13 denotes a handle cam member locking member pivotally supported on the second fixed shaft 12 in the same manner as the stopper piece 11 for the locking piece. This locking member 13 opens the right thumb and index finger to the left. The lower second engaging portion 13b, which is formed in a suitable L shape and corresponds to the thumb of the right hand when the locking piece 2 is locked or which faces the left and right direction (including the oblique direction), is a handle cam member. The handle cam member 3 is prevented from rotating by engaging with the tapered tip 3d.

  On the other hand, a movable pin 14 that protrudes in the horizontal direction is provided at the upper end portion of the upper first engaging portion 13a corresponding to the index finger or directed upward, and the movable pin 14 is a follower piece to be described later. It engages with the fingertip-shaped lower end 61c of 61. Reference numeral 15 denotes a spring member that always urges the lock member 13 in a direction in which the lock member 13 is engaged (locked) with the handle cam member 3 in a state where the central portion is wound around the second fixed shaft 12.

  Here, for convenience of explanation, with reference to FIG. 1, a brief description will be given of how the above-mentioned stopper piece 11 for a lock piece operates by an operating force of an operating member such as a lever handle or a pushbull handle (not shown). To do.

  In the above configuration, for example, when the outer operating member is operated, the outer projecting piece 6 presses the side surface of the short first engaging portion 3b of the handle cam member 3, and similarly, the inner operating member is operated. Then, the inner protruding piece 5 presses the short-piece-shaped first engaging portion 3 b of the handle cam member 3. In FIG. 1, one of the inner and outer protrusions 5 and 6 is horizontally moved to the left by the operation force of the operation member, whereby the handle cam member 3 is an arrow that is counterclockwise with the first fixed shaft 4 as a fulcrum. It will rotate in the A direction.

  Therefore, as long as the lock member 13 for the handle cam member 3 does not exist, the small roller 7 of the handle cam member 3 slides on the arc-shaped notch engaging portion of the stopper piece 11 for the lock piece, Since the second fixed shaft 12 is pushed upward with the fulcrum as a fulcrum, the engaging tip of the stopper piece 11 for the lock piece is moved upward from the engaged portion formed in a step shape on the upper side of the lock piece 2 in the upward direction of the arrow B. As a result, the handle cam member 3 can rotate in the clockwise direction indicated by the arrow A. As a result, the lock piece 2 moves backward in the direction indicated by the arrow C via the arm-shaped second engaging portion 3c of the handle cam member 3. Is possible.

  However, in the locked state of FIG. 1, the second engaging portion 13 b below the handle cam member locking member 13 engages with the tapered tip portion 3 d of the handle cam member 3 to prevent the rotation of the handle cam member 3. doing. Therefore, in order to change the lock piece 2 from the locked state to the unlocked state, as a precondition, the lock member 13 is locked to the handle cam member 3 by the driving force of an electric drive source (for example, a solenoid) 51 described later. Need to be resolved.

  Therefore, the main part of the present invention and matters related to the main part will be described. In addition, in the internal space of the vertically long lock box 1, a biasing means including a dharma rotating by an operating force on the cylinder lock or the thumb turn side, a power conversion member for converting the dharma's rotational force into a linear motion, and a lock member locked state A large number of members such as a maintenance piece that temporarily supports the elimination of the problem, and a guide means for guiding the maintenance piece are incorporated, but these descriptions are omitted because they are not related to the limiting requirements of the present invention.

(2) Matters Relating to the Main Part of the Present Invention Matter related to the main part of the present invention will be described with reference to FIGS. In the description of the matters related to the main part of the present invention, specific configurations of the electric drive source 51, the drive piece 55 and the driven piece 61 connected to the drive source are disclosed in Patent Document 4, Since it is a well-known matter by description in patent document 5 etc., the detail of this well-known matter is omitted as much as possible, and the difference is pointed out.

  In FIG. 1, FIG. 2, etc., one follower 61 is omitted on the front side of one drive piece 55, while the other follower is omitted on the other side of the drive piece. (Main switching lever and auxiliary switching lever) are drawn, but in order to understand the technical idea of the invention, other driven pieces and switching means are omitted for convenience.

  At the implementation level, for example, as shown in FIG. 6, one drive piece 55 has one driven piece 61 (in this embodiment, the first engagement above the inner and outer lock members 13 on the lower end side). A bifurcated engagement portion that engages with the portions 13a and 13a), or there are inner and outer driven pieces 61 and 61, and there is one driven piece 61 or inner and outer driven pieces 61 and 61. A part of the auxiliary switching levers 70, 70 of the inner and outer switching means enter the side-by-side state in the one driving piece 55 so as to engage with each other.

  Therefore, as shown in FIG. 7, the lock members 13 and 13 with which the inner and outer driven pieces 61 and 61 engage are also independently present inside and outside, and the handle cams with which the inner and outer lock members 13 and 13 are respectively engaged and disengaged. Members 3 and 3 also exist independently inside and outside.

  First, FIG. 2 is a schematic explanatory diagram of the energization locking mode (R mode). On the other hand, FIG. 5 is a schematic explanatory diagram in which the power is turned off and unlocked in the R mode. As described in Patent Document 4, Patent Document 5, and the like, there are modes such as an energization unlocking mode (T mode) in addition to the energization locking mode (R mode). A description will be given by taking the locking mode (R mode) as an example.

  Each mode of the R mode in FIG. 2 and the T mode (not shown) is similar to Patent Document 4 and Patent Document 5 in the “non-energized state” when the electric signal is applied. It shows that the operating rod 52 has expanded and contracted in the direction of the arrow against the spring force of the return compression spring 53.

  Therefore, in the case of the R mode in FIG. 5, when the power is turned off, the operating rod 52 of the drive source 51 expands and contracts in the direction opposite to the arrow direction by the spring force of the return compression spring 53. In the embodiment, the drive source 51 is fixedly installed in a substantially central portion of the internal space of the long box-shaped lock box 1, and the operating rod 52 of the drive source 51 is horizontal to the rear wall 1 c of the lock box 1. It is oriented to the state (difference from Patent Document 4). In addition, Patent Document 4 and the like further refer to the anti-panic mode (A mode), but of course, the A mode switching unit and the like may be added to the embodiment of the present invention.

  Now, the drive source 51 employs an electromagnetic plunger. Of course, a drive motor, a transmission gear, etc. can be used instead of the electromagnetic plunger. As described in Patent Document 4, by applying an electrical signal to the solenoid of the electromagnetic plunger, the operating rod 52 moves a predetermined amount in the horizontal direction. The drive piece 55 (similar to the drive connector 147 in FIG. 11 of Patent Document 4) 55 has a pistol-like overall longitudinal cross-sectional shape, and the connecting portion 55a that protrudes in the lateral direction corresponding to the grip portion is the protrusion of the operating rod 52. Connected to the tip. Therefore, the driving piece 55 cooperates with the operating rod 52 of the driving source 51.

  This drive piece 55 is mainly different from the drive connector 147 of Patent Document 4 in that it is on one side of the upper end of the vertically long drive plate portion (side wall) 55b having the vertical long hole 56 and on the vertical line of the vertical long hole 56. This is the point where the longitudinal groove 57 is formed (see FIG. 3). Further, a relatively large diameter escape hole 58 that allows the drive piece 55 to expand and contract in a horizontal direction by a predetermined amount is formed in communication with the vertical elongated hole 56, and the escape hole 58 is connected to the lateral fixed shaft 60. Is a point that penetrates with play.

  Next, FIG. 3 is an explanatory diagram of the driving piece 55 and the driven piece 61. The driven piece 61 is rotatably supported by a fixed shaft 60 that penetrates the escape hole 57 of the drive piece 55 in a state of being provided side by side with at least one side surface (vertical side surface) of the drive piece 55. Similar to Patent Document 4, the follower piece 61 is formed in a central portion 61a having a shaft hole 62 and an ear portion in the center portion, and a continuous portion 61b having a dog-shaped follower slot 63. And a finger-like lower end portion (corresponding to the connecting claw 161) 61c extending below the continuous portion, this point is substantially the same as the switching cam 159 of FIG. Further, the position is displaced in the horizontal direction together with the drive piece 55 by the drive force of the drive source 51.

  However, the follower piece 61 is different from the switching cam 159 of Patent Document 4 in that the finger-like lower end portion (lower end engaging portion) 61c of the follower piece 61 is directed downward and the handle lock member 13 is moved upwardly. It is a point which engages or links with the movable pin 14 of the 1 engaging part 13a.

  Next, FIG. 4 is an explanatory diagram of the main switching lever 66 and the auxiliary switching lever 70 that constitute the switching means 65. A pair of switching means 65 exists at least for the inside and outside. Therefore, as described above, the inner and outer auxiliary switching levers 70 are provided on both side surfaces of the drive piece 55, for example, via the inner and outer driven pieces 61 (FIG. 6). Note that the size and form of one drive piece 55 is appropriately designed in consideration of the shape and structure of the inner and outer driven pieces.

  4 and 5, the switching means 65 has a rectangular support frame 80 whose tip 66a is directly in the opening formed in the back plate 1b of the lock box 1 or in the opening of the back plate 1b. Is fixedly mounted (embodiment), it is located in the opening 81 of the support frame 80 (indirectly located in the opening of the back plate 1b) and is located in the center or near the center. 66b is a long main switching lever 66 pivotally supported by a horizontal shaft 67, and an auxiliary switching lever 70 linked to the rear end 66c of the main switching lever via a linkage (engagement protrusion, engagement hole). The auxiliary switching lever 70 includes an engaging protrusion 71 that engages with both the driven elongated hole 63 of the driven piece 61 and the vertical elongated hole 56 of the driving piece 55 at the lower end 70a thereof, and the driving piece at the intermediate portion. Guide protrusions engaged with the longitudinal grooves 57 formed on the vertical lines of the 55 vertical elongated holes 56 Each having an association elongated hole 73 to 2 and the upper end. Desirably, the auxiliary switching lever 70 is formed in an angle shape of a substantially right-angled body.

  As shown in FIG. 5, the support frame 80 is provided with a grid-like movable frame body 82 whose upper end is pivotally supported and which selectively supports the front end portion 66a of the switched main switching lever 66. ing. The grid-like movable frame body 82 and the long strip-shaped main switching lever 66 are known matters (Japanese Patent Laid-Open No. 2003-239586). The main difference from the known matter switching levers is the switching means 65 of the present invention. Is a point where a new auxiliary switching lever 70 exists. Note that the click piece 66d provided on the main switching lever 66 and the click-protruding protrusion 85 provided in the lock box 1 are known matters, and thus detailed description thereof is omitted.
