  Hereinafter, the best mode for carrying out the present invention shown in FIGS. 1 to 6 will be described.

(1) Environment for Implementing the Invention FIG. 1 is a schematic explanatory diagram showing the environment for implementing the invention. In FIG. 1, 1 is a door frame that forms an opening of a building, for example, 2 is a receiving bracket attached in a vertical frame on the door end side of the door frame 1, and 3 is an opening / closing body that opens and closes the opening of the door frame 1 (A hinged door or a sliding door) and X are locks attached to the inside or the inner wall surface of the door 3 on the door end side. Y is a counter device for the lock provided in the lock box 4. In this embodiment, the counter device Y is disposed immediately above the dead bolt 5. As is well known, the lock box 4 of the lock X is composed of a case body 4a having a front 4c on the front surface and a case lid 4b for closing one side opening of the case body 4a. The counter device Y is preferably arranged near the dead bolt 5 or the dharma 7.

(2) Main components of the lock X: 5 is a dead bolt that moves forward and backward with reference to the doorway 6 of the front 4c, 7 is a dharma that is a term for those skilled in the art and is rotatably provided on a support seat (not shown), and 8 is a dead bolt 5 A dead stopper 9, disposed in a lower space on the inner end (rear end) side, is disposed between the dead stopper 8 and the dharma 7, and moves the dead stopper 8 in the direction of disengagement. And a pressing member that can be pressed down.

  Thus, on the upper part of the inner end portion of the dead bolt 5, a first engagement convex portion 5a and a second engagement convex portion 5b having an inverted C-shaped inclined surface are formed. A drive arm 7a extending radially outward of the dharma 7 is selectively press-engaged with the uninclined inclined surfaces of the first engagement convex portion 5a and the second engagement convex portion 5b.

  The dead bolt 5 is moved forward and backward by the driving force of the dharma 7 via, for example, a guide pin 11 that engages with an indefinite horizontal guide elongated hole formed on the inner end side of the dead bolt 5. FIG. 1 shows a state in which the dead bolt 5 is locked with the receiving metal fitting 2 by the driving force of the dharma 7. On the other hand, FIG. 2 shows the unlocking time when the dead bolt 5 is retracted into the lock box 4 by the driving force of the dharma 7 (the dharma 7, the dead stopper 8 and the like are omitted).

  Although it is a detailed matter, the base end portion of the dead stopper 8 is pivotally supported by a fixed shaft (reference numeral omitted) and is always urged in a direction in which the dead stopper 8 is engaged with the dead bolt 5. An urging spring (not shown) is provided. The ten-hand-shaped push-down member 9 has one end pivotally supported at the tip of the drive arm 7a and the other end guided by a guide (not shown) provided at the lower part of the lock box. It is biased by a spring (not shown).

  Each drawing explaining the present embodiment is only for explaining the technical idea, and the shape, size, etc. of each constituent member are not in accordance with the actual design drawing. In particular, a claw wheel 16 of the lock counter device Y, which will be described later, a feed engagement piece 18, a single or plural small gears (this embodiment), a shift projection 36 and a shift small gear 37, numbers on the outer periphery, The shape and size (dimensions) of the display rotating body or the like having signs such as symbols and patterns are drawn for convenience of explanation. Therefore, for example, the number of teeth of the internal teeth of the initial rotating body 25 with respect to the number of teeth of the external teeth (10 in the embodiment) of the plurality of small gears 31 and 33 (this embodiment) rotating together with the claw wheel 16. Since (in the embodiment, 100) is very large, the gear ratio between the external teeth of the small gears 31 and 33 and the internal teeth of the initial rotating body 25 is, for example, “sufficient 1” even if it is a schematic diagram in the drawing.

  In addition, in this embodiment, the large-diameter initial rotating body 25 that rotates through the external teeth of the small gears 31 and 33 that cooperate with the ratchet wheel 16 is not a unit number as low as one or ten. It is handled as the number of units. Therefore, the second and subsequent rotating bodies are rotation display boards of thousands or tens of thousands.

(3) Counter device for lock Y is a counter device for lock. This counter device Y is operated via the dead bolt 5 that is operated by the driving force of the dharma 7 (for example, the first embodiment), not via the dead bolt 5 (the fourth embodiment), or is also operated with the dharma 7. 48 is provided with the interlocking means, or the deadholt 5 is provided with the interlocking means (utilization invention including the present invention), and the usage frequency of locking or unlocking of the locking means is counted.

First, as shown in FIG. 1, the opposed support piece 13 having a cross-sectional channel shape is fixed to the inner wall surface of the wide side wall of the case body 4 a, and the pair of opposed support pieces 13 are used to lock and unlock the locking means. The counter case 14 having the display window 14e for displaying the information is fixedly incorporated.
Therefore, the counter case 14 is fixedly positioned in the space portion 12 between the front 4 c of the lock box 4 and the dharma 7 or the space portion 12 directly above the dead bolt 5. Here, “fixed” means that the counter case 14 does not rotate at least in the circumferential direction. When the case lid 4b is removed from the case body 4a, the counter case 14 is supported oppositely on the lock box side. It can be pulled out from the piece 13.

(4) Counter case shaft and rotating body The counter case 14 has a lever-like feed engagement piece 18 pivotally supported on one side wall 14a thereof, and an engagement tooth 16a which engages with and disengages a claw 18a of the feed engagement piece 18. And the toothed wheel 16 of the rotating shaft 22 supported by the one side wall 14a and at least one small gear 33 that cooperates with the rotating shaft 22 and the number of teeth is set larger than that of the small gear 33. A large-diameter initial gear (in the first embodiment or the like, a mark may be provided on the outer periphery of the initial gear) 25 and a plurality of shift means 36 and 37 after the initial gear 25 is rotated. A plurality of counter display rotating bodies 26 to 30 are provided on the fixed shaft 21 of the counter case 14 so as to be rotated in the forward direction so that the display frequency is added.

  A driven means 45 having an operating rod 48 guided by a guide 47 is disposed below the counter case 14 so that the constituent members of the counter case 14 can be operated.

  Here, the shaft and the rotating body mounted on the shaft will be described. Now, in the counter device Y, a fixed shaft 21 is horizontally mounted at the center of opposite side walls (side plates) 14a, 14b of the counter case 14. In the present embodiment, a rotary shaft 22 for a claw wheel is fitted on one end of the fixed shaft 21 (on the right side in FIG. 5). That is, one end portion of the fixed shaft 21 is fixedly supported in a state of being inserted into the rotation shaft 22 for the toothed wheel supported by the shaft hole of the one side wall 14 a of the counter case 14.

  On the other hand, the other end portion (left side in FIG. 5) of the fixed shaft 21 is elastically sandwiched by a bifurcated regulation support plate 23 fixed to the other side wall 14b of the counter case 14 or the inner surface of the bottom wall. The fixed shaft 21 is appropriately fixed by a restriction support plate 23 of the present embodiment, an elastic piece (not shown) fixed to the wall of the counter case 14, a fixing means, and the like. Depending on the design, the restriction support plate 23 may be formed at the end of a cylindrical support member described below.

  Next, 24 is a cylindrical support member fixedly provided in the counter case 14. This cylindrical support member 24 has a function of guiding each rotating body, a function of allowing rotation of the shift projection 36, a function of supporting the shift small gear 37, and a sliding resistance to the display rotating bodies 26 to 30. And the like (described later).

  Next, a plurality of count display rotating bodies (including 25 in some embodiments) 26, 27, 28, 29, and 30 are mounted on the fixed shaft 21 so as to be rotatable in the forward direction.

  On the other hand, on the inner end side of the rotating shaft 22, the number of teeth is set to be smaller (10 in the embodiment) than the number of teeth of the internal teeth 25a of the initial rotating body 25 (100 in the embodiment). A plurality of small gears are arranged. Here, for convenience of explanation, the first fixed gear 31 that is directly fixed to the inner end portion 22a of the rotating shaft 22 is pivotally supported on one side wall 14a of the counter case 14 so as to mesh with the first small gear 31. The second small gear 32, which is pivotally supported on one side wall 14a of the counter case 14 so as to mesh with the second small gear 32, and meshes with the internal teeth 25a of the initial rotating body 25 is a third small gear. It is called gear 33.

  In addition, as shown in FIG. 3, it is the conditions that the ratio of the 1st small gear 31 and the 3rd small gear 33 which cooperate with the ratchet wheel 16 is the same. Further, depending on the design, only one small gear may be used.

  Since the first small gear 31 to the third small gear 33 cooperate with the claw wheel 16 via the rotary shaft 22, when the claw (engaging tooth) 16a of the claw wheel 16 advances by one, The third small gear 33 rotating via the small gear 31 and the intermediate gear 32 also advances one at a time.

  Further, as described above, the internal teeth of the initial rotating body 25 with respect to the external teeth of the small gear 33 that rotates together with the ratchet wheel 16, for example, when the tooth of the small gear 33 advances by one, the initial rotating body 25. Therefore, when the ratchet wheel 16 rotates once, the initial rotating body 25 rotates “tenths of a hundred”. In addition, when the ratchet wheel 16 is rotated ten times, the initial rotating body 25 rotates once (one tenth).

  Therefore, the first display rotator 26 is a thousand unit rotation display board, the second display rotator 27 is a 10,000 unit rotation display board, and the third display rotator 28 is a hundred thousand units. The rotation display plate, the fourth display rotator 29 is a million display unit, and the last display rotator 30 is a million display unit.

  If comprised as mentioned above, the rotation display board 30 of 10 million units is also possible in the range which can utilize the space in the lock box 4. FIG. As described above, depending on the design, the initial rotating body 25 can also be a hundreds of rotation display plates.

(5) Counter case, restriction support piece, support member, etc. Here, the counter case 14, the restriction support piece 23, the cylindrical support member 24, etc. will be described in detail. First, as shown in FIG. 5, the counter case 14 is a hollow drum having a shaft hole at the center of both side walls 14 a and 14 b. Therefore, the reference numeral 14c corresponds to the circumferential trunk portion. As shown in FIG. 3, a pair of engagement protrusions 14d are provided on the left and right sides of the outer surface of the peripheral body portion 14c to slide-engage with the opposing support pieces 13 on the lock box side. The counter case 14 is removably incorporated in the lock box 4 via a pair of left and right engaging protrusions 14d. That is, the counter case 14 is fixedly inserted into the lock box 4 or pulled out via the pair of engaging protrusions 14d.

  Further, as shown in FIG. 4, a display window 14e is formed in a lateral direction at an appropriate portion of the peripheral body portion 14c. From the display window 14e, each number of the display rotating body 26 (right display rotating body in FIG. 5) to the largest rotating body 30 (leftmost rotating body in FIG. 5) is one by one. One looks sideways. Each of these numbers is information indicating the long-term use frequency.

  Next, the regulation support plate 23 will be described. In the present embodiment, the restriction support plate 23 fixes the fixed shaft 21 and restricts the last rotating body 30 having the largest unit. Therefore, the regulation support plate 23 is fixedly incorporated inside the counter case 14 on the side of the other side wall 14b. Thus, the restriction support plate 23 includes an attachment base end portion 23a fixed to the inner wall surface of the other side wall 14b, and an elastic clamping portion 23b extending in a forked manner from the upper end portion of the attachment base end portion 23a. The fixed shaft 21 is fixedly held by an elastic holding portion 23b. In other words, the fixed shaft 21 is horizontally installed in a state where it is fixedly supported by the elastic regulation support plate 23 and the rotary shaft 22 at the center of both side plates 14 a and 14 b of the counter case 14.

Next, the cylindrical support member 24 having a circular opening will be described. As described above, the cylindrical support member 24 has a function of guiding the rotating body, a function of passing the shift projection 36, a function of supporting the shift small gear 37, and a function of giving resistance to the rotating body by the support plate portion 24a.
