Japanese Patent Laid-Open No. 10-077756 Japanese Patent Laid-Open No. 10-102852 Japanese Patent Laid-Open No. 11-006340 JP 2000-166721 A

  The above-mentioned interior lock of the sliding door lock has a structure in which the hook can be operated from the indoor side, and even when the sliding door is open at the time of unlocking, the hook can be swung out to the outside. When tightened, the hook crashes into the outside summoning jar, causing unpleasant noise, and may damage one and / or the other of the impacted members.

  Therefore, conventionally, a trigger device is attached to the inner summing lock, and the mechanism is such that the hook can be swung out only when the summing bowl is polymerized.

  That is, a housekeeper who operates the key does not normally have a trigger device because the housekeeper who operates the key does not open the sliding door with the key inserted into the cylinder lock.

  However, according to the concept of so-called fool-proof, a trigger device must be provided on the outside summit lock in response to an erroneous operation.

  Therefore, the present invention provides an outside summing lock that prevents the unlocking arm from swinging outward when the sliding door is open at the time of unlocking, thereby eliminating the above-described disadvantages. It is aimed.

In order to achieve the above object, an invention according to claim 1 is directed to an outer frame mounted on an outdoor summoning tub, and a guide that extends vertically in the outer frame and is movable in the vertical direction. Rack plate, a cylinder lock with a pinion that engages with the rack plate mounted on the inner cylinder, and a base end that is rotatably supported by a horizontal arm shaft in the outer frame. An arm drive mechanism that is linked to a rack plate that moves up and down by operation of a lock key of a cylinder lock that is selectively swinged outward, and that selectively swings the lock and unlock arm outward. The rack plate is guided so as to be movable between a notch extending in the vertical direction at a side edge at one end portion of the rack plate, and an operating position engaged in the notch and a standby position outside the notch. With a stopper Through the strike plate of the outer frame is movably guided in vertical longitudinal direction strike plate, it is urged forward at the outer person to form a stopper at the inner end, also the front end horizontal projection Yamagata And a trigger rod that moves the stopper to the standby position when the rods that are summed together are superposed .

The outside summit lock according to the present invention configured as described above is configured such that when the sliding door is open at the time of unlocking, the trigger rod is activated and the stopper is engaged in the notch in the operating position. Even if it is turned, the rack plate is hooked on the stopper to prevent the unlocking arm from swinging out. Therefore, it is completely prevented from colliding with other bags due to the swinging and unlocking arm swinging out. It has the expected effect of being able to.

  A trigger device is provided on the outside summon lock, and it is applied when the sliding door is open at the time of unlocking, so that the unlocking arm cannot be shaken out, completely preventing the arm from colliding with other hooks. did it.

An embodiment of the invention described in claim 1 will be described below with reference to the drawings.
As will become apparent later, the present invention can be realized regardless of the structure of the outer summing lock having the rack plate that is moved up and down by the operation of the key combination, and is described in Patent Documents 1 to 4 described above. It can be used for any summon lock.

  However, since the embodiment shown in the figure is an outside summing lock having a new structure, the outside summing lock itself will be briefly described below.

  As shown in FIG. 1 and FIG. 2, the outer summing lock generally indicated by reference numeral 1 includes an outer frame 2 serving as an outer case, and this outer frame 2 is attached to a bag outside the inner chamber of the summoning rod not shown. Has been.

  Above the outer frame 2, a cylinder lock 3 with a key hole facing the outdoor side is mounted, and a pinion 4 is mounted on the inner cylinder of the cylinder lock 3 as shown in FIG.

  The pinion 4 is also engaged with the rack plate 5. As shown in FIGS. 3 and 4, the rack plate 5 extends in the vertical direction along the inner surface of the side plate of the outer frame 2, and integrally connects an arm drive mechanism 11 described later below.

  Then, a key is inserted into the cylinder lock, and the rack key 5 is pushed down by rotating the key from the insertion angle position by a predetermined angle in the clockwise direction, and the unlocking arm 6 (see FIGS. 2 and 5) is watched in FIG. It is rotated in the direction, and an engagement piece 7 (see FIGS. 6 and 7) in the inner frame described later is pushed up and unlocked.

  On the other hand, when the key is rotated counterclockwise, the rack plate 5 is raised, the locking arm 8 is rotated counterclockwise, and the engagement piece 7 is pushed down to lock.

  As shown in FIGS. 2 and 5, the above-described application and unlocking arms 8 and 6 are thick plate lever bodies whose overall shape is a substantially square shape, and each of the base ends is a horizontal arm in the outer frame 2. The shafts 9 are supported so as to be able to rotate independently of each other, and are urged in the direction of being drawn into the outer frame 2 by the elasticity of a torsion coil spring (not shown).

  As shown in FIGS. 2 and 5, the arm driving mechanism 11 of the applying and unlocking arms 8 and 6 is a frame having a U-shaped horizontal section integrally coupled to the lower side of the rack plate 5.

  Then, a push-down step portion 13 with a relief groove 12 is formed on the sleeve portion on the near side in FIG. 5 of both sleeve portions, and a push-up step portion 14 with the relief groove 12 is formed on the opposite sleeve portion, respectively. Each engages with or engages with an engagement pin 15 implanted at the proximal end of the unlocking arm 6 and an engagement pin of a locking arm 8 (not shown) (see FIG. 2).

  Then, as described above, the key is inserted into the key hole of the cylinder lock and is rotated in a predetermined direction, and the rack plate is lowered to rotate the locking arm 8 counterclockwise in the figure, and the engagement piece 7 Press down to lock.

  Note that the cylinder lock in the illustrated embodiment is applied by inserting the key into the key hole, rotating it by a predetermined angle in a predetermined direction in response to the unlocking operation, and then rotating it back by the same angle to lock the key at the key insertion angle position. Operate to pull out.

  Further, by raising the rack plate 5, the unlocking arm 6 is swung out in the clockwise direction, and the engaging piece 7 is pushed up and unlocked. In either case, the arm that is not engaged with the arm drive mechanism 11 is drawn into the outer frame by its biasing force.

  Next, the internal summing lock that forms a sliding door lock in combination with the external summing lock having the above-described configuration is configured as described below.

  That is, in FIG. 6 and FIG. 7, reference numeral 16 indicates an inner frame, which is attached to an indoor summoning tub (not shown) and has a shallow vertically long side (the right side in FIG. 7) opened. A front plate 17 is mounted so as to cover the opening on the outer surface of the box-shaped body.

  Further, below the inner frame is supported by a support shaft 18 so that a front end portion (outer end portion) formed into a bowl shape is rotatable.

  Furthermore, a drive plate 21 extending in the vertical direction and guided so as to be movable in the same direction is disposed in the inner frame 16.

  The drive plate 21 is a member obtained by bending a plate material below a half of the operation window 22 opened in the front plate 17 into a U-shaped cross section, and a rectangular connection above the portion parallel to the front plate 17. The hole 23 is open.

  On the other hand, as shown in FIG. 7, the inner frame 16 is attached to the inner summoning tub in such a manner that the indoor side support block 25 is called by the mounting screws 24, 24 penetrating the inner frame 16.

  An operation member 26 is provided on the indoor side of the support block 25 so as to be movable in the vertical direction. The operation member 26 includes a connection rod 27 having a rectangular cross section and the connection hole 23. It is connected to the drive plate 21 through engagement.

  On the other hand, the upper edge of the front side sleeve plate 21a of the drive plate 21 in FIG. 72 is bent inward to form the horizontal engaging piece 7 facing the operation window 22.

  A driving pin 28 is attached to the lower end portion of the driving plate so as to penetrate the driving plate in the paper surface direction. The driving pin 28 has a cross section formed on the inner end portion of the cam 19 having a dharma. The engagement hole 29 is loosely fitted.

  With the configuration described above, the drive plate 21 is linked to the paddle 19 via the drive pin 28. As shown in FIG. 7, the drive plate 21 is positioned downward by the operation of the operation member 26 or the operation of the key combination. When the hook 19 is swung outward, as shown in FIG. 2, the hook 19 pushes the lid member 31 of the outer summing lock 1 into the outer frame 2 and opens the strike plate 32 without an unnumbered strike. It is inserted into the hole and thus locks the sliding door lock.

  On the other hand, when the drive plate 21 is lifted, the hook 19 is housed in the inner frame 16, so that the inner and outer frames become free from each other, and the sliding door lock is unlocked.

  In addition, although the trigger device shown by the code | symbol 33 in FIG. 7 is provided in the internal summing lock, since this trigger device 33 is not the summary of this invention, further detailed description is abbreviate | omitted.

  Returning to the description of the external summon lock, as shown in FIG. 4, a notch 34 extending in the vertical direction is formed at the rear side edge of one end (upper end) of the rack plate 5.

  A trigger rod 36 (see FIGS. 8 and 10) integrally formed with a stopper 35 in the vicinity of the notch 34 is movable in the front-rear direction (left-right direction in FIGS. 4 and 10) perpendicular to the strike plate 32. Guided.

  Further, as shown in FIG. 9, the trigger rod 36 is formed in a horizontal projection mountain shape as shown in FIG. 9, and as shown in FIG. 4, as shown in FIG. ).

  Therefore, in a normal state where no external force acts on the trigger rod 36, the stopper 35 elastically contacts the notch 34.

  Furthermore, the relative positional relationship between the trigger rod 36 and the rack plate 5 in the vertical direction indicates that when the inner cylinder of the cylinder lock is at the key insertion angle position, that is, the standby angle position, the rack plate at the standby position corresponding to the angular position. It is assumed that the trigger rod 36 is located at the center of the notch 34 in the vertical direction.

  The outside summing lock according to the invention described in claim 1 configured as described above is provided with a chevron at the tip of the indoor summoning bowl and the trigger bowl 36 in the process in which the summing bowl is polymerized by closing the sliding door. The trigger rod 36 is pushed into the outer frame 2 by the wedge action that occurs between the two.

  Then, as apparent from FIGS. 4 and 9, the stopper 35 integrated with the trigger rod moves backward and away from the notch 34 of the rack plate, so that the rack plate 5 can be moved up and down, that is, the locking and unlocking can be performed. It becomes possible.

  On the other hand, when the key is inserted into the key hole of the cylinder lock while the sliding door is open and rotated, the rack plate 5 moves up and down in accordance with the rotation of the key. At this time, the stopper 35 is placed in the notch 34. Since it is engaged, the rack plate 5 is stopped by the stopper and cannot move. In other words, it is impossible to swing out the unlocking and unlocking arms, and the above-described inconvenience can be prevented.
