Description

  The present invention relates to an electric lock for a joinery, and more particularly to an electric lock for a joinery characterized by a guide mechanism of a drive arm constituting the electric lock.

  Patent Document 1 describes an example of an electric lock for joinery, and the electric lock includes a clutch mechanism. For example, a dead bolt repeats locking and unlocking by an electric force. This patent document 1 has been proposed by the applicant.

  By the way, this type of electric lock has components such as a control unit, a drive motor, a gear transmission means, a clutch mechanism, a drive arm, and a dharma, and the deadbolt moves forward and backward in the manner of operation described below. Repeat locking and unlocking.

  That is, when the drive motor is driven by the control unit, the clutch gear of the clutch mechanism Y rotates in a predetermined direction via the gear transmission means. When the clutch gear rotates in a predetermined direction, for example, a drive arm having an engaging projection that engages with an engaging portion of a clutch plate that constitutes the clutch mechanism Y is pressed in the vertical direction to operate. At this time, the driving force (transmission force) of the driving arm is transmitted to the dharma, and is transmitted to the dead bolt through, for example, the crank arm or not.

  On the other hand, this type of electric lock can be switched from electric to manual operation, and the operation member can be operated to lock and unlock the dead bolt. At this time, the clutch of the clutch mechanism Y acts, and the drive arm can freely move to a predetermined position.

Therefore, in this type of electric lock, it is desired that the engagement protrusion of the drive arm move smoothly regardless of whether the electric force or the manual force is used. However, in Patent Document 1, there is no mention of a guide mechanism that improves the operation of the drive arm. Therefore, it is desirable to have a guide mechanism that makes the drive arm operate well when the drive motor is driven and when the operation means is operated.

  Hereinafter, the best mode for carrying out the present invention shown in FIGS. 1 to 13 will be described.

(1) Main components of the electric lock X First, basic items will be described with reference to FIGS. As shown in FIG. 1, the electric lock X of the present invention includes a control unit 2, a drive motor 3, a gear transmission means 4, a clutch mechanism Y, a drive arm 5, a dharma 6, a crank arm 7, a dead bolt in a lock box 1. 8. A long plate-like guide plate 9 is provided.

  That is, the electric lock X includes a control unit 2 provided in the lock box 1, a drive motor 3 controlled by the control unit 2, a gear transmission unit 4 that transmits a driving force of the drive motor 3, and a transmission power of the gear transmission unit A clutch mechanism Y for transmitting the signal, a drive arm 5 that operates via a clutch member of the clutch mechanism Y, a dharma 6 connected to the drive arm 5, and a dead bolt 8 that moves forward and backward via the crank arm 7 by the driving force of the dharma 6. I have.

  Although the crank arm 7 is not a limiting requirement of the present invention, in the embodiment, the crank arm 7 is interposed between the dharma 6 and the dead bolt 8, and the crank arm 7 is fixed in a horizontal state in the lock box 1. The long plate-like guide plate 9 is interlocked with the dharma 6 via a plurality of movable pins 11 and 12 that engage with the guide portion 10.

  Accordingly, as shown in FIGS. 1 and 10, the control unit 2 is electrically connected with an unnumbered detection means for detecting the position of the dead bolt 8 being applied and unlocked. The drive motor 3 is disposed in the lateral direction, and is driven by being controlled (applying / unlocking voltage applied) by the control unit 2. The gear transmission means 4 includes a plurality of gears, and transmits the driving force of the drive motor 3 to the clutch gear of the clutch mechanism Y. The clutch mechanism Y includes a clutch member that engages with and disengages from the clutch gear (for example, an engaging claw piece, a clutch plate, and a spring member). When the drive plate is driven, the clutch plate that constitutes the clutch member rotates together with the clutch gear. The engagement projection 15 of the drive arm 5 is controlled by the track control means 21 disposed symmetrically on the cam plate 16 via the engagement portion of the clutch plate 36 and the track ( For example, the annular recess 19 is moved cyclically. As a result, Dharma 6 and 7 are interlocked, and the dead bolt 8 repeats locking and unlocking.

  On the other hand, for example, the clutch mechanism Y uses the driving force of the dharma 6 that is rotated by the operating force of an operating member (for example, a key, thumb turn) (not shown) as the clutch gear via the rotation (for example, idle) of the clutch plate 36 of the clutch mechanism Y. Cutting is possible with respect to the (drive motor 3) side.

  Specifically, for example, even when the key is repeatedly operated from locking to unlocking and from unlocking to locking in the normal time, the clutch plate 36 is rotated idly by the drive arm guide mechanism Z including the guide plate 9. Therefore, the clutch gear is not affected by the operating force of the operating member at all.

  In addition, even if the operation is switched from electric to manual operation and the operation member is repeatedly applied and unlocked, the engaging claw pieces do not mesh with the ratchet teeth of the clutch gear, and the clutch plate continues to idle in the same direction. At this time, the engagement protrusion 15 of the drive arm 5 interlocked with the dharma 6 moves on the track of the cam plate 16 while being controlled by the track control means 21 described above. In the present embodiment, the engagement protrusion 15 moves cyclically in the same direction when the drive arm 5 reciprocates by the operation force of the operation member and when the drive arm 5 reciprocates by the drive force of the drive motor 3. At the same time, since the driving arm 5 repeats reciprocating motion in the vertical direction, the electric lock can be repeatedly locked and unlocked via the dharma 6 interlocked with the driving arm 5.

The guide elongated holes 24 and 24 are engaged with each other and connected to the spring member 23.

  Accordingly, the inner side of the other end 22b facing the starting points a and b (stop points a and b) of the engaging protrusions of the respective position displacement guide bars 22 is arranged so that the engaging protrusion 15 is positioned at the starting point. It is formed in an arc 25 so that it can be reliably guided.

  The link means of the one end portion 22a of the position displacement guide bar 22 includes, for example, an engagement small hole 26 formed in the one end portion 22a, and an unnumbered projection shaft that enters the engagement small hole 26 is formed in the cam plate 16. Has been. Further, the linking means of the other end portion 22b is, for example, engaging protrusions 27 and 27 engaged with the guide long holes 24 and 24, respectively. These engaging protrusions 27 and 27 are guide lengths as shown in FIG. It is connected to the spring member 23 through the holes 24 and 24. Therefore, each position displacement guide bar 22 displaces the other end 22b outward and inward with the one end 22a as a fulcrum when the engaging protrusion 15 is cyclically moved in the same direction. To control. Therefore, the engagement protrusion 15 does not deviate from the annular track.

(3) Clutch mechanism Y
Although the specific configuration of the clutch mechanism Y is not a limiting requirement of the present invention, an example of the clutch mechanism Y will be described here with reference to FIGS. 8 and 9 as related matters.

  The clutch mechanism Y of the electric lock has a clutch gear 31 that transmits the driving force of the driving motor 3 controlled by the control unit 2 to the Dharma 6 side. As shown in FIG. 8A, the clutch gear 31 having an unnumbered central axis has a recess 32 formed on the upper surface on one side, and has a predetermined interval on the inner peripheral surface of the recess 32. A plurality of ratchet teeth 33 are formed. A plurality of engaging claw pieces 35 shown in FIG. 8B are incorporated into the recess 32 of the clutch gear 31 so as to be positioned on a concentric circle of the central axis (see FIG. 9). A circular clutch plate that rotates together with the latch gear via a plurality of engaging claw pieces 35 is incorporated into the recess 32. The plurality of engaging claw pieces 35 and the clutch plate are connected to each other through linkage means 35a and engaging small holes 36a.

  In addition, the clutch plate 36 and the engagement claw piece 35 are combined with the clutch gear 31, one end portion of the engagement claw piece 35 is pivotally supported by the clutch plate 36 via the linkage means, and the other end portion is the clutch gear. When the clutch gear 31 receives a driving force from the drive motor 3 side and rotates in a predetermined direction when engaged with and disengaged from the ratchet teeth 33 formed in the recess 32 of the recess 31, as shown in FIG. The clutch plate 36 rotates together with the clutch gear 31 by engaging the other end of the piece 35 with the ratchet teeth 33.

  On the other hand, when the operating force from the Dharma 6 side is transmitted to the clutch plate 36 via the drive arm 5, the other end of each engagement claw piece 35 does not mesh with the ratchet teeth 33, and FIG. ), The clutch plate 36 rotates at least a required amount.

(4) Clutch plate 36 of clutch mechanism Y
As shown in FIGS. 7 and 8, the clutch plate 36 of the clutch mechanism Y has an engaging portion (cam projection) 37 at the peripheral end portion of one side surface, and the engaging portion 37 is engaged with the driving arm 5. The other side of the protrusion 15 is engaged. Therefore, the engagement projection 15 of the drive arm 5 is controlled by the projection portion of the other side portion that engages with the engagement portion 37 of the clutch plate 36 of the clutch mechanism Y and the track control means 21 of the guide mechanism, and the annular track 19. And a projecting portion on one side that moves.

(5) Other Configurations and Actions First, as shown in FIG. 1, the dharma 6 provided with sickle pieces has a plurality of connecting projections in the radially outward direction. One of them is connected to a dharma biasing means 41 that switches and biases in a predetermined direction corresponding to the position position (locking position and unlocking position). The dharma urging means 41 includes an unnumbered bar-shaped connecting rod and an urging spring wound around the connecting rod.

  Next, one end portion 7 a of the crank arm 7 is connected to the first dead movable pin 11 of the hollow deadbolt 8, and the second crank movable pin 12 provided in the intermediate portion of the crank arm 7 is The other end 7 b of the crank arm 7 is engaged with the guide portion 10 of the guide plate 9, and is pivotally attached to the first connection protrusion protruding outward in the radial direction of the dharma 6.

(6) Locking / Unlocking of Dead Bolt 8 As described with reference to FIG. 10, when the clutch plate 36 is rotated by the driving force of the drive motor, the dead bolt 8 repeats locking and unlocking. FIG. 11 is a schematic explanatory view showing that the drive arm 5 reciprocates in the vertical direction by the electric force, and as a result, “the dead bolt 8 repeats locking and unlocking”. On the other hand, FIG. 12 is a schematic explanatory view showing that the drive arm 5 is manually reciprocated in the vertical direction and, as a result, “the dead bolt 8 repeats locking and unlocking”. FIG. 13 is a conceptual diagram showing that the engaging protrusion 15 is guided by the guide mechanism Z and always moves cyclically in the same direction. As is apparent from FIGS. 12 to 13, the control unit 2 of this embodiment controls the drive motor 3 so that the clutch gear 31 repeats rotation in one direction. When the clutch gear 31 rotates in one direction, the clutch plate 36 also rotates in the same direction, whereby the engagement protrusion 15 of the drive arm 5 repeats a circular trajectory by the guide mechanism Z.

  Here, an example of the locus of the engaging protrusion 15 will be described with reference to FIG. At the time of unlocking (when the dead bolt is retracted), the engagement protrusion 15 of the drive arm 5 is at a position a below the track (for example, annular recess) 19, for example.

  Therefore, if a voltage for locking is applied to the driving motor 3 from the control unit 2 that has acquired the locking signal, the driving motor 3 is activated and the driving force is transmitted to the gear transmission means 4. The transmission power of the gear transmission means 4 is transmitted to the clutch gear 31 of the clutch mechanism Y as described above. When the clutch gear 31 rotates in the direction of arrow A shown in FIG. 9A, the clutch plate 36 of the clutch member rotates together with the clutch gear 31 as described above. It moves in the annular recess 19 while being pressed by the engaging portion 37 of the clutch plate 36 and being controlled by the track control means 21 of the guide mechanism Z.

  In other words, the engagement protrusion 15 is controlled by the position displacement guide bar 22 so as not to deviate from the track, and moves to the upper position b. When the drive motor stops, the engagement protrusion 15 stops at the point b. In this embodiment, when locking (when the dead bolt protrudes), the engaging protrusion 15 is at a point b opposite to the point a (see FIG. 11).

  Next, when the unlocking voltage is applied to the drive motor 3 from the controller 2 that has acquired the unlock signal, the drive motor 3 is restarted, and the driving force is the gear transmission means 4 as described above. To be told. At this time, the clutch gear 31 rotates in the same direction (arrow A) as in the case of locking, and the clutch plate 36 also rotates in the same direction A. In other words, the engaging protrusion 15 returns from point b to point a while drawing an arcuate trajectory on the opposite side. Therefore, when the locking and unlocking are repeated, the engagement protrusion 15 is cyclically guided by the guide mechanism Z, and the drive arm 5 repeats the reciprocating motion in the vertical direction.

  FIG. 12 shows locking and unlocking by manual operation force. Manual operating force is transmitted from the Dharma 6 side to the engaging portion 37 of the clutch plate 36 via the engaging protrusion 15 of the drive arm 5.

  When the clutch plate 36 is independently rotated in a predetermined direction, the arcuate outer peripheral surface of the engagement claw piece 35 slides on the arcuate inner peripheral surface of the ratchet teeth 33, so that each engagement claw piece 35 is not shown in FIG. Displaces inwardly against the spring force, with the projection axis as a fulcrum.

  Therefore, the engagement claw at the other end of each engagement claw piece 35 does not mesh with the ratchet teeth 33, and the clutch plate 36 rotates at least by a required amount. At that time, since the engaging projection 15 of the drive arm 5 is guided by the guide mechanism Z, it moves cyclically in a fixed orbit as in the case of application / unlocking by the drive force of the drive motor.

  In the embodiment shown in the embodiment of the invention, the engagement protrusion of the drive arm is used in the meaning of the engagement portion. Further, the clutch mechanism Y is an example, and the present invention is not limited to this. For example, a clutch mechanism of an electric lock (not shown) combines a clutch member in which a clutch plate, an engaging claw piece, and a catch plate for an engaging claw piece are unitized into a recess of the clutch gear. One end of the piece is pivotally supported by the clutch plate via a linkage means, and the other end is engaged with and disengaged from the ratchet teeth formed in the recess of the clutch gear, and the clutch gear receives the driving force from the drive motor side. The clutch plate rotates together with the clutch gear by engaging the other end of the engaging claw piece with the ratchet teeth. On the other hand, the operating force from the dharma side is passed through the drive arm. When transmitted to the clutch plate, the other end portion of the engagement claw piece does not mesh with the ratchet teeth, and the clutch plate rotates at least a required amount.

  The present invention is mainly used in the locksmith and joinery industries.
